A Week at the Lake with My Sister

It was a normal family vacation until...

In 2018, I published "A Week at the Lake with My Sister". It was the longest story I had written at over 53K words, so I decided to split it up into five chapters. I made some poor plotting choices, particularly in chapter 4. As a consequence, I received a lot of negative comments on the last two chapters. But the story was published, I learned my lessons from it, and I moved on.

I read every comment I receive, and, as the years went by, I came to dread getting new comments on chapter 4 as they were almost always very critical. I thought about taking down the whole series, but I didn't want to take down that much work, and I did get some enjoyable comments on it. A reader convinced me to rewrite the story to fix the poor plotting choices. I decided to not change the first three chapters, so the new version would be an alternative reality to the original chapters 4 and 5. One decision would be different, and that would lead to a very different story. For a while, I was thinking I'd publish two new chapters (4A and 5A) and revise the original chapters 4 and 5 to say that there were now alternative versions of those chapters the reader should probably read first. Later, I decided that if I published alternative versions of chapters 4 and 5, very few people would read them. I decided if I was going to take the time to rewrite six pages of story, I'd republish the whole thing as a stand-alone story so all that work would get read. I did that in 2022. That version was longer than the original at 62K words.

After I published that version, I exchanged PM's with a reader about the story, that reader convinced me that the story needed an epilogue, but I wasn't going to publish a 5K word sequel to a 62K word story.

I took all of my stories down at the beginning of 2023, and I'm taking advantage of republishing them to add an epilogue to this story, taking the word count up to 67K.

"You want me to do what?" I asked my sister Kaitlyn in surprise.

"Please, Brandon. Please date Joanna for the summer." Joanna was her long-time best friend. "I think you'll have a great time together, and she really needs to date a better class of guy. It would mean so much to me."

I knew I should have suspected something when Kaitlyn had baked my favorite cake this afternoon. She had waited until I had eaten a big slice before asking. "Joann is nice, and I like her, but we've never clicked. And she can find a boyfriend quite easily on her own."

Kaitlyn sighed. "Yeah, she can, but she always finds the wrong kind of guy." I knew what was coming. "The good-looking, super-confident guys with a lot of money that turn out to be jerks. The last one really did a number on her."

"What did he do?" I did like Joanna as a friend, and I didn't like hearing a guy had hurt her.

"He introduced her to coke." Kaitlyn's anger rose as she spoke. "Then she caught him cheating on her; he apologized and said it was a terrible mistake; she took him back; and when she caught him cheating on her again, he totally blamed her for his cheating."

My jaw dropped. "How could it be her fault?"

"She had gotten flabby; she wasn't giving him enough sex; she was just using him for the coke, and he had wised up." Kaitlyn had counted off on her fingers as she had gone through the list. "All bullshit, but it's destroyed her self-confidence."

"Asshole." I hated guys who treated girls like shit.

"Exactly. He's the worst guy she's dated, but she keeps dating losers like him. That's why I want you to date her for the summer."

I stalled by asking, "Do you know the difference between a porcupine and a BMW?"

Kaitlyn gave me a little grin. "No."

"With the porcupine, the prick is on the outside."

Kaitlyn laughed. "Too true. At least it's been too true for Joanna." Kaitlyn frowned slightly. "Look, Brandon, I know you two have never clicked, but just for the summer, could you do it? It's not like you've got a lot of other options, do you?"

I had broken up with my last girlfriend a little over a month ago. In the three years since I had graduated, I had lost touch with most of my friends from high school. I didn't know a single girl I could ask out now that I was home for the summer. I liked Joanna, and I'd love to have a girlfriend for the summer, but...

"Even though I have a lot of fun with Joanna when she's with you, I've never been able to keep a conversation going with her when it's just the two of us."

Kaitlyn said, "It's because you intimidate her." I snorted. "Seriously. She's always had a big crush on you. She would talk with me all the time about you. I think she's wanted you to like her so much that she's never been able to relax around you. I think you'll have a lot of fun with her once she gets used to being with you."

I had always suspected Joanna had a crush on me, and what Kaitlyn said sounded plausible. Why not give her a chance?

But before I could say anything, Kaitlyn said, "How about this, Brandon; the three of us will go out. If you're having a good time, then act like it's a date. I won't mind being a third wheel."

That was an interesting idea. "What about Paul?" Paul was Kaitlyn's boyfriend. As Kaitlyn and I attended the same university, I had met him briefly a couple of times. He lived three hours away and would be visiting on weekends.

"I don't want to double-date. When Paul's here, I want to be totally focused on him. But during the week, you, Joanna, and I could go out."

"I'd be up for the three of us going out," I added to keep expectations reasonable, "No promises, but I'll give Joanna a chance."

* * * *

Tuesday, Joanna was waiting outside of her apartment building. I hadn't seen her in a long time as she could only afford to go to the local community college, but she looked as good as I remembered her; black hair that came down below her shoulders, dark brown eyes, dark eyebrows, dark lashes that boldly stood out against her light olive complexion, and lips on the thin side that formed a pretty smile when she saw us pull up. She was wearing a white tank top that showed off her nice upper body. Her tits were on the small side but fit her slim figure. Sexy legs extended below her light blue shorts. Joanna had played volleyball in high school and had had a firm body. She wasn't in that same shape, but she still looked damn good to me. How a guy could call her flabby was beyond me.

Kaitlyn got out of the passenger seat and got in the back seat so Joanna could sit next to me. When Joanna got in the car, she said, "Hey Brandon. Long time, no see."

"Ditto. You look great. Are college and work treating you well?"

"I love my job. School's okay. Classes are too easy, and there are some spooky kids in my classes."

As I headed toward the mall, Joanna told me about her college experience. On the way, my phone rang. When I checked it, I saw that the Caller ID was "United States," so I sent it to voice mail.

"Who was that?" Joanna asked. "The girl you're going to go out with after you drop me off?" She tried to make it sound like she was teasing, but it was too barbed and insecure.

Not a great start to a date. "This girl who works at a furniture store. She keeps calling me even though I've told her time and time again that all I was looking for was one nightstand."

Kaitlyn snorted and then cracked up. Joanna joined in laughing, and the tension diffused.

We went to the mall, had dinner, and shopped for a while. As I expected, Joanna and I didn't talk much directly to each other. Instead, she and Kaitlyn would talk, and I'd jump in occasionally; or Kaitlyn and I would talk, and Joanna would jump in occasionally. Still, it was a lot of fun.

We went to a movie, where Kaitlyn had me sit in the middle. About halfway through, Kaitlyn jabbed me in the ribs with her elbow, and I took that as a hint to hold Joanna's hand. When I took it, Joanna gave my hand a squeeze. After the movie was over, we walked hand-in-hand as we exited the theater.

On the way to my car, Kaitlyn asked, "How about I drive, and you two sit in back?"

I looked at Joanna, who nodded. "Okay." I reviewed how the date went, as we continued walking to my car. I had had fun, but only because Kaitlyn was along. I decided tentatively that I'd like to go out with Joanna again, but only if Kaitlyn went with us.

Kaitlyn said, "How about we go back to our house?"

Joanna said, "Your parents are probably getting ready for bed."

Kaitlyn replied, "They're always happy to see you."

I suspected that if Joanna went to our house, Kaitlyn would push for her to spend the night with me. It was way too early for that. "Let's take Joanna home."

Kaitlyn gave me a look that could have melted paint as I gave her my keys. I held the door open for Joanna to sit in the backseat, and then went around the car to join her. We held hands on the drive back to her apartment while we talked to Kaitlyn about the movie. When we got to her apartment building, I got out, opened the door for her, and gave her a goodnight kiss. Kaitlyn moved over to the passenger seat, and I got in behind the wheel.

Kaitlyn said, "You could have done more."

I raised my hand in a what-were-you-expecting? gesture. "Maybe I could have, but I'm fine with how the evening went. I had a good time, and we had no awkward moments."

"It's that...she's agreed to be your girlfriend for the summer. You didn't give her a chance to be."

"We've gone on one date. It's too early to talk about her being my girlfriend."

"I asked you to date Joanna for the summer. The whole summer. That's what you agreed to."

"What? No." I shook my head. "I didn't agree to her being my girlfriend for the whole summer. I only agreed to go out with her. One date at a time, and no promises as to how long I'll date her."

"Well...I want her to go to the lake with us. And that's in five weeks."

Dad's family owned a cabin on a lake five hours away from us. It was a small, three-bedroom place that in years past we visited several times each summer. This year, because of my job, we'd only spend one full week there.

"Is Paul going to the lake with us?" I asked.

"Yes. Mom and Dad have already approved it. And I can tell you from personal experience it's no fun being single at the lake when your sibling has their significant other."

Yeah, it had sucked for Kaitlyn the last two years. She had had to go with my parents in the evening when they had taken a walk to give me and my girlfriend privacy.

"Maybe Joanna won't want to go to the lake."

"She's already asked for the time off." Joanna had gotten a job at an insurance office after high school and had gotten Kaitlyn a job there for the summer. "I've convinced her that she needs to get used to having a good guy as a boyfriend, so she's ready to be your girlfriend. That includes sex."

I laughed. "Because I'm a good guy, I'm not going to push her to have sex before she's ready."

Kaitlyn flashed me a you're-an-idiot look. "She's ready. If you had taken her to our house, you could have made love tonight. She loves sex, and she's hot for you."

I shook my head in amazement. "Well, I'm not ready to have sex yet. I feel like I'm still getting to know her."

Kaitlyn snorted. "She's been my best friend for six years. She's been constantly at our house that whole time. You've spent lots of time with her."

"I've known her as your friend but not as someone I was interested in. I need to warm up to her."

I didn't know what Kaitlyn wanted from me. I had told her upfront that I wasn't wild about Joanna. Just because she had talked Joanna into that it'd be a good experience to have me as a boyfriend didn't mean it'd work well for us to jump into bed together. I wasn't looking for sex; I was looking for a relationship in which sex happily fit. It takes time to build that kind of relationship. How could Kaitlyn not understand that?

* * * *

The next day was the first day of my summer job; one Dad had gotten me at a golf course where he regularly played. I was going to be working eight-to-five, Wednesday-to-Sunday.

After work, I went home and cleaned up for another night out with Kaitlyn and Joanna. When I got in the car with Kaitlyn, she asked, "How was work?"

"Okay. I spent the morning driving golf carts from the barn to where golfers drive off in them. Once things slowed down there, I went with a groundskeeper to trim bushes on the course and to haul trimmings. For the last two hours, I drove golf carts from where the golfers dropped them off to the back side of the barn, washed them off, and put them away. My boss told me to run whenever I went to or from the barn, and I did."

"Sounds like a lot of running."

"A lot of hard work. I'm tired. You and Joanna are going to crush me tonight."

Kaitlyn laughed.

We picked up Joanna and went to play tennis. Kaitlyn and I had been on the tennis team in high school and Joanna had learned to play from hanging around with Kaitlyn. Joanna and Kaitlyn were on one side and I was on the other. Facing them both, I couldn't help noticing the contrast between the two. Both were pretty, but in very different ways. Kaitlyn had lightly-freckled pale skin, brilliant blue eyes, and honey-brown long hair that was braided into a ponytail. She was much curvier than Joanna, with broader shoulders, an ample bust and wider hips. I enjoyed watching both of them bounce around the court. I was the better player, but I was tired and had to cover more court so they won 6-1, 6-2, 6-1.

Afterward, the three of us sat down at a picnic table close to the courts. I held Joanna's hand while we talked. After five minutes, Kaitlyn said, "I'm going to go for a walk."

Once Kaitlyn was out of earshot, I asked Joanna, "So what do you think of us dating?"

"If Kaitlyn hadn't pressured you into doing it, I'd be loving it." She shrugged her shoulders, implying she wasn't loving it. "But she's right that I need to date better guys and all the girls you dated while I was in high school said you were a really good boyfriend."

"They told you that?" I asked incredulously.

"Yeah. Well, all the girls you dated were good friends of mine!"

I thought back to the girls I had dated. They had all been friends of Kaitlyn, which made them friends of Joanna as well. "Well, I can't help it that my sister kept bringing home girls I got along well with."

"But you never got along well with me." It was a statement of fact.

I needed to turn this around. "I wasn't the type of guy you were looking for and I didn't see any point in giving you unwanted interest." I had said that matter-of-factly, but then I said more positively, "We're getting along fine now."

I leaned forward and kissed Joanna. She smiled and her eyes twinkled. I waited for her to initiate the next kiss. She did, and we kissed gently for the next few minutes.

I asked, "How's your mom doing?"

Joanna sighed. "She's dating another loser and I'm afraid she's getting close to inviting him to move in."

"Why is he a loser?"

"He's like so many of the guys my mom has been involved with -- can't commit to a relationship. He'll live with Mom for a couple of years and then drift on out. Mom's saying 'This time it'll be different', but it never is. At least I'm old enough that he doesn't have to pretend he's going to be my dad. I hated that." It must have been tough having father-figures appear and disappear. "But if he moves in, I'm moving out."

Joanna's body language was weird. When Kaitlyn had been with us, she had been relaxed and had talked lightly and carefree. Now, she was tense and uneasy. It was like she felt that she had to say something about her mom because I had asked, but she wasn't comfortable talking to me about her.

I asked, "Where would you move to?"

"I don't know. Kaitlyn and I have talked about subletting a place for the rest of the summer. I told her that I didn't want her spending money on rent just to help me, but she said Paul's not comfortable with staying at your parents', so he'd probably help with the rent if we got a place."

"Why isn't he comfortable staying at my parents'?"

"Because it's weird. What parents let their kids have people spend the night with them?"

I was a little surprised by her question. "Don't you know the story behind that?"

"Vaguely. It had something to do with Chelsea." Chelsea had been one of my high school girlfriends.

"Well, it really starts with my two cousins, Piper and Reagan."

Joanna searched her memory. "I don't think I've met them. Kaitlyn hasn't mentioned them much."

"They're much older than her. Piper is five years older than me, and Reagan is two years older. We'd do things with them at the lake house during the summer, but we were never close because of the age difference. They're my dad's brother's daughters and my dad's brother's family used the lake house like we did until Piper's summer before her senior year in high school."

"What happened then?"

"Piper had a serious boyfriend. My aunt and uncle were planning on spending two weeks at the lake house, and she didn't want to be apart from him that long. Her family forced her to go, and she whined and moped the whole two weeks. When she graduated from high school, she moved in with her boyfriend and hasn't been to the lake house since."

"Ouch!" said Joanna sympathetically.

"It gets worse. The summer before Reagan's senior year, she had a serious boyfriend and didn't want to go to the lake house. My aunt and uncle said she could bring her boyfriend to the lake house, and she seemed fine with that. But then my aunt and uncle wouldn't give her and her boyfriend any privacy. Reagan wanted to sleep with her boyfriend, and her parents said no. Reagan and her boyfriend fought with my aunt and uncle for the whole two weeks. Once Reagan graduated from high school, she moved in with her boyfriend and hasn't been to the lake house since."

"Double ouch! Do your aunt and uncle still go to the lake house?"

"Well, after a rough couple of years, everyone seems to have patched things up. They're going to the lake house for a long Fourth of July, and my cousins will be there with their boyfriends."

"That's good."

I nodded my head. "It is. My parents have been really upset about the situation. Kids pull away from their parents, but I don't think any parent wants their kid to pull away that hard and that fast. My parents sure don't." My parents loved spending time with Kaitlyn and me. "So that's the background. The summer before my senior year of high school, I'm dating Chelsea and I don't want to go to the lake house for two weeks."

"That must have frightened your parents. They'd seen that horror movie twice already."

"They knew it was coming, so they were prepared."

Joanna crinkled her nose. "But you went, didn't you? I went with Kaitlyn that summer, and Chelsea didn't come."

"Yeah. I went because my parents offered me a deal: if I went to the lake house that summer and continued doing family trips; then when I turned eighteen and became an adult, they'd respect my right to have privacy with my adult girlfriend. That meant I could have girls spend the night and take them to the lake house with me."

"So you forced them into letting you have girls sleep over?"

I made an unhappy face. Joanna's face fell, like she was kicking herself for saying something that made me unhappy. "I wouldn't say force. If they had said I had to go to the lake house, I would have moped a little, but I wouldn't have taken it as badly as Piper did. But my parents didn't want to risk it. A lot of other parents give my parents grief for the deal, but my parents push back with that they think they are more involved with my life because of it." I smiled. "I like it. I don't have to pretend I'm not having sex with a girl, and I don't have to struggle to find someplace where we can be alone. I wouldn't bring a one-night-stand home, but I'm not a one-night-stand kind of guy. I don't know if I would have come home for the summer without it. It's worked so well for me that my parents gave Kaitlyn the same deal." Joanna nodded in understanding. "My parents seem to genuinely enjoy it when Kaitlyn or I have someone spend the night as they want to get to know well the people we're dating. So there's no reason for Paul to feel uncomfortable about staying at our house."
"I'd find it uncomfortable. And he's got a lot of money. His dad owns a good-sized business and puts a LOT of money into Paul's checking account each month. Paul is working for his dad for the summer, so he has even more money. I think that's his main appeal to Kaitlyn -- he spends a lot of money on her."

"He does?"

Joanna wouldn't look at me when she talked. When she was done talking, she'd sneak a peek at me. I wished she would be like she was when Kaitlyn was with us.

"Yeah. Don't get me wrong -- she's not dating him just because he spends a lot of money on her. He sounds very sweet. She loves him; not I-want-to-marry-him love but I-really-want-to-see-where-this-goes love." Joanna paused and sneaked a peek at me to gauge my reaction. "If Paul won't help with the rent, Kaitlyn said she'd tried to convince your parents to let me live with them. She's such a great friend. Has Kaitlyn told you we're going to get an apartment together in the fall?"

This was big news. "No."

"I got a big raise at work for my one-year anniversary, so I can afford to change schools now instead of waiting another year. Everything had seemed set until Mom said something about her loser moving in."

I squeezed Joanna's hand. "I wish you luck." We weren't far enough along in our relationship for me to offer more than that.

She leaned forward and we had another round of kissing. Once we started kissing, she relaxed and went back to having positive body language. She was a good kisser with soft lips that she used in a variety of ways. Because we were in a public place, I didn't feel comfortable Frenching and apparently neither did Joanna. We stopped after a few minutes and went back to holding hands.

We discussed our plans for the weekend. Our kissing had relaxed her some, but she was still uncomfortable. We hit a lull in our conversation, which lasted until Kaitlyn came around the corner of the tennis courts. The look on her face showed disappointment, like she was expecting to find us fucking on the grass.

When we got in the car, Kaitlyn asked, "Do you want to go back to our house?"

Again, I had the feeling that Kaitlyn was trying to get Joanna to spend the night with me. "No. Let's drop Joanna off and go home. I'm exhausted and just want to go to sleep."

Joanna and I snuggled in the back of the car while Kaitlyn drove us to her apartment. Joanna was much more aggressive than at the tennis courts and had me hard most of the drive. I decided she wasn't comfortable chatting with me, but she was very comfortable making out with me. After I kissed Joanna goodnight, I took over driving. Kaitlyn's silence told me she had expected me to do more with Joanna.

I said, "I had fun tonight. Thanks for coming along. Having fun with you tonight made me regret that I didn't visit you very often at college."

Kaitlyn softened immediately. "That's okay. You were busy, and I wanted to make my own life."

"You're a fun person to be with. Joanna is a lot more fun when she's with you. You're probably wanting me to go out with just her from now on, but I think all of us will have more fun if we keep going out together." I paused to emphasize my next point. "And fun is what I'm looking for with Joanna right now."

I felt like going slow was the right thing. From what I understood, Joanna was drawn to guys who wanted to get into her pants right away, and I was showing her that we should establish a relationship that makes her want to have sex before we actually have sex.

Kaitlyn was quiet for a while and then said, "You know, you used to be such a big presence in my life. You dated my friends, you flirted with them when you weren't dating, you gave me rides everywhere, and you helped me with my homework. And then you were gone, off to college. Hanging out with you and Joanna makes me realize how big of a void your absence created in my life."

"But you had your boyfriends. And now you have Paul."

Kaitlyn brightened. "I do have Paul."

* * * *

Thursday night, the three of us did the grocery shopping for the week for the two families. I started "accidentally" bumping and rubbing against Joanna, and she quickly got into doing the same. She and I giggled a lot, and Kaitlyn would roll her eyes whenever we got a little carried away.

On the way to Joanna's apartment, I asked Kaitlyn, "Looking forward to seeing Paul?" He'd be arriving tomorrow for the weekend.

"You bet. I've missed him a lot. He's very sweet and he constantly does nice things for me. This week alone, he's sent me two 'I love you' cards and a small box of chocolates. He makes me feel so loved."

"Sounds like a great guy. What's his major?"

"Electrical Engineering. We had calculus together spring semester. He sat next to me on the first day of class and introduced himself, and we hit it off. Two weeks later, we went on our first date, and we've been together ever since."

* * * *

Friday, Joanna came home from work with Kaitlyn and stayed to meet Paul. I could tell Paul's large physical presence surprised Joanna; he was probably 6'3" and very wide. I'm 6'1" and looked small next to him. His shaved head added to his intimidating physical presence.

We spent the evening talking, getting to know Paul. I had expected him to brag about how he liked to kill alligators with his bare hands, but it turned out he was a big nerd. He loved talking about sci-fi movies and the latest electronic gadgets, and proudly showed off his brand-new top-of-the-line iPhone like a proud father shows off his baby.

At ten, Joanna announced it was time for me to take her home.

Kaitlyn said, "You can spend the night, Joanna."

She shook her head. "I didn't bring any of my stuff."

We all knew that Kaitlyn had everything Joanna would need, but I was fine with her not staying. I was getting pretty sweet on her and was ready to have sex, but I wanted her to pick the time and place.

As I drove Joanna home, I said, "I had fun tonight. I wish you had spent the night, but there's no rush."

Joanna squeezed my hand. "Thanks. I had fun too. Listen -- tomorrow night, Mom and her loser might go out for the evening. They won't decide until the last minute, so stay flexible, okay?"

I smiled at what she was suggesting. "Okay."

"And don't tell Kaitlyn I told you to stay flexible."

* * * *

Saturday was nuts at work. Saturday is the busiest day of the week for a golf course and since it was a perfect day, the golfers never stopped coming. I spent almost the whole day working the golf carts.

When I got home, Paul and Kaitlyn were about to leave for the evening.

Paul asked, "Are you going out with Joanna later?"

"No. She's busy with her mom. After dinner, I'll go over to a friend's house to play Fortnite. Do you play Fortnite?"

"A little. I mainly play Total Galactic War."

"That's a mobile game, right?"

Paul's eyes lit up. "Have you played it?"

"No."

"It's a great game." He described it enthusiastically while Kaitlyn crossed her arms and rolled her eyes. I got the feeling she had heard this spiel many times. I enjoyed playing computer games and I was never as enthusiastic about a game as Paul was about his.

When Paul paused to think of how to describe a game feature, Kaitlyn grabbed his arm and pulled him toward the door. "You boys can talk more about the game tomorrow." And then they were gone.

* * * *

While I was having dinner, I got a text from Joanna. Call me when you leave the house.

When I got in my car, I called Joanna.

"Hey, Brandon."

"Hey, Joanna."

"My mom has gone out with her loser. I've got the apartment to myself for a few hours. Come on over."

"Will do."

I called my friend to say something had come up and I couldn't make it over for Fortnite. I drove over to Joanna's, and when I entered her apartment, she said, "Let's go to my bedroom."

I shook my head. "No, not yet. Let's start out here."

I took Joanna's hand and led her over to the dining room where I had her sit down in a chair. I said, "Do you know you have a beautiful neck?" I bent forward and kissed it lightly. She sucked in her breath. I worked my way down her neck, the kisses occasionally turning into soft nibbles as I stroked her arms. I heard her breath quicken as I did. Joanna was wearing a light blue tank top that exposed most of her shoulders and I kissed my way across her right shoulder.

I went slow -- as slow as I could stand -- and drove Joanna's lust steadily up to a fever pitch. When I was done, we moved to her bedroom where I slowly undressed her, covering her body with kisses, licks and nibbles. When my tongue touched her pussy, she came for the first time. I made her cum again before I slowly fucked her. When I filled her pussy a second time, she was glass-eyed.

"That was the best sex I've ever had," said Joanna as I lay on my side next to her, holding her hand.

I kissed her and said, "Perfect. I wanted to make our first time special." I brought her hand to my lips and kissed it. "Ready to cuddle?"

"Oh, yes."

I lay down on my back in Joanna's bed, and she put her head on my shoulder. She said, "I liked going slow. A guy has never gone that slow with me."

"I like going slow. The more you enjoy it, the more I enjoy it; and the more time we spend getting each other excited makes the finale more pleasurable for me. I don't like rushing anything about being with a girl."

Joanna smiled at me and then said, "Well, Kaitlyn is in a big rush." I laughed. "You're not going to tell her about this, are you?"

"Not if you don't want me to."

"I don't want you to. I know she's trying to be helpful, but I wish she wasn't so bossy."

"My sister? Bossy?" I guffawed and Joanna joined in.

"Seriously," said Joanna. "The only reason you're here tonight is she badgered both of us into agreeing to be a couple for the summer."

I didn't like Joanna's last sentence. "I'm here because I want to be. And I want you to spend the night with me at my house."

Joanna got off my chest and looked me in the eye. "Are you sure your parents would be okay with me spending the night in your bedroom?"

"Absolutely. I told you about the deal. And as they like you a lot, I suspect they'd let you spend the night with me even if the deal wasn't in place."

Joanna put her head back on her shoulder. "I still can't."

"Why not?"

"Why? Well...I'd have to get permission from my mom, and she and I never discuss sex. We act like neither of us has sex. She got me an IUD when I was fifteen and that's it. She's probably over at her loser's place right now getting fucked. She never brings her men here until they're moving in, and then she acts like they never fuck."

I shrugged. "You've slept over at our house a million times. Tell her you're sleeping over again."

Joanna shook her head. "I could do that, but...if I spent the night with you, it'd be like a public declaration that you're my boyfriend, and you're not."

I was shocked by her statement. "I am your boyfriend."

"Oh, I know. I agreed to it; you agreed to it. But we're only acting like we're boyfriend and girlfriend. Then it'll be all over at the end of the summer."

I realized Kaitlyn pushing us together so hard had caused a massive negative side effect. "Did you want to make love tonight?"

"I had agreed to do it."

Not the answer I wanted to hear. "Before I entered you, did you want me to fuck you?"

Joanna blushed lightly. "Yes."

"And I wanted to fuck you. Do you want to make love with me again some other day?"

Again, Joanna blushed. "Yes."

I gave her a gentle hug. "In my book, that makes us boyfriend and girlfriend."

* * * *

The Saturday before we were to leave for the lake, I was over at Joanna's again. Sex had changed considerably between us. The first time, Joanna had been passive, letting me do what I wanted. Now, she was much more aggressive. Tonight, as soon as I got in the door, she pulled down my shorts, pushed me onto the couch and sucked me off. After I had cum, I started to get up to go to her bedroom, but instead Joanna threw a towel on the couch and told me to eat her pussy there. I expected us to go to her bedroom after I had made her cum, but instead Joanna had me sit up, and then she straddled my lap and bounced up and down on my cock until I came. We kissed for a while as she continued to sit on my lap, our juices slowly leaking out and on to me.

"You're such a naughty girl," I said.

Joanna smiled. "I wanted to do something different. I like different." She liked different positions, but this was our first time in a different room.

"I loved different," I said with a big smile. Joanna kissed me. "But you weren't just naughty tonight. You were very naughty Thursday, going braless while we played tennis." Joanna chortled. "You kept distracting me with your bouncing tits. That was very unfair."

Joanna laughed some more. "Kaitlyn dared me to do it."

"Did she dare you to flash me as well?"

Joanna cracked up. "Yes, she did. Then she dared me to put your hand on my tits on the drive back to the apartment. I told her I didn't want to go that far with you. You should have seen the face she made." Joanna roared with laughter. "She was practically pulling her hair out. I love that she has no idea we're fucking."

"Well, she'll know Wednesday when you sleep over." I had finally convinced Joanna to spend the night with me as a dry run for the week at the lake.

"You haven't told her I'm going to sleep over, right?"

"Right." Per Joanna's instructions.

"I'm going to let her talk me into it at work on Tuesday." She gave me a big wink. "But we're only going to sleep together. Maybe I'll let you feel my tits. But the panties are going to stay on." Joanna roared with laughter again and then gave me a kiss. "I'm having so much fun with you."

"And I with you." Fun was the word we had settled on to describe our feelings for each other. It was too early to use love. It had taken several weeks, but Joanna had finally got comfortable talking with me. She liked to tease and act saucy, and she was getting a big kick out of having sex with me behind Kaitlyn's back.

I said, "Let's go to your bedroom for round two."

Joanna pulled off my cock and pushed the towel against her pussy. When she had cleaned herself, she handed me the towel and I wiped off.

I got up and we headed toward her bedroom. Joanna said, "Let me get another towel." She winked at me. "It's a good thing I do all the laundry."

I was lying on my side on her bed when she came in. She lay down next to me and asked, "Do you like me, Brandon?"

Was this a trick question? Of course I liked Joanna. "I like you a lot, Joanna. You're very special to me. I'm very glad we're dating. You're my naughty girl." Was she wanting me to us the 'L' word? I was getting close to telling Joanna that I loved her, but I wasn't quite there yet. I didn't want to overstate my feelings or my commitment to her.

Joanna was quiet, like she was waiting for me to say more. I didn't have anything more to say. Then she pushed me on to my back. She wrapped her hand around my soft cock and said, "There's one way I'll never be naughty."

"How's that?"

"I'll never have a threesome with you and Kaitlyn."

I laughed. "I'd never expect you too."

"Almost every boyfriend I've had has asked me to arrange a threesome with Kaitlyn."

"Seriously?" Joanna nodded. "That's terrible!"

"It is! Why would I arrange for my best friend to have sex with my boyfriend? He's my boyfriend! I don't want to share."

"As you should." Then I had a wicked thought. "Though seeing some girl-girl action between you and Kaitlyn would be hot."

Joanna's eyes narrowed. "Don't go there. We're both heterosexuals. If we were open to a sexual relationship, we'd have done it long ago. How would you respond if I told you I want a threesome with you and one of your buddies, and I want to see some guy-guy action during it?"

I snorted. "I'd gently decline the opportunity."

"So you want to see your sister naked having sex?"

I was instantly mortified. "Of course not. It's just that..."

Joanna laughed at my embarrassment. "You were thinking about it being hot to see me with another woman, and not the woman you were suggesting?"

I was thankful she had offered me a way out of my faux pas. "Exactly."

Joanna nodded. "But seriously, asking for a threesome is the kiss of death for a relationship. It tells me he only thinks of me as a provider of sex."

I kind of felt like this was a test, that Joanna was keeping her hand on my cock to see if a talk of a threesome would get me hard. She continued to grasp my cock lightly in a non-exciting way. Time to try to get myself out of this test. "I'm sorry I suggested the girl-girl action between you and Kaitlyn. I only want to be with you. And joking about you and Kaitlyn was particularly poor taste as she's my sister and she's very happy with Paul."

Joanna cocked her head. "Are you sure?"

Sure about what? "They're very happy whenever I see them."

"How much time do you spend with them?"

I wasn't prepared for this line of questioning. Kaitlyn and Paul were obviously happy together. Paul traveled a long way every weekend to see Kaitlyn. They slept together Friday and Saturday night. I assumed they fucked like bunnies on both of those nights.

I said, "Look, you told me that Kaitlyn loved him."

"I know. Does she act like she's in love with him when you're with them?"

I was stunned by this development. "I see them only a little before they go out for the evening." I left for work before they got up. "How much time do you spend with them?"

"None. But she sounds different now when she talks about him. She liked him a lot more at college."

"Has she told you anything about their relationship changing for the worse?"

Joanna shook her head. "No, but Kaitlyn never says anything negative about a boyfriend while she's dating him. After she's broken up with him, she tells me everything."

I wasn't comfortable talking about how my sister might not be as in love with her boyfriend as it appeared. I wanted her to be happy. "I'm going to think she's in love with him until I see otherwise."

Joanna smiled. She still held my cock loosely in her hand. "Do you know who I think she has the hots for?"

"Besides Paul? No one."

Joanna smiled bigger. "You."

"Me?" I chortled. "No way."

"You should have heard her when she suggested to me I have you as my summer boyfriend. Boy, did she ever sing your praises. 'Every girlfriend he's had has said he's a great boyfriend.'"

Suddenly, I felt very defensive. I couldn't help but play down her statement. I shrugged and said, "Well, it's true."

"She's much more excited and animated talking about how you're a great boyfriend than she is when she talks about Paul."

Why the hell was Joanna bringing this up? I had an attractive sister, but she was my sister. There was no way she'd have any interest in me. "That doesn't mean anything."

Joanna gave me a knowing smile. "Kaitlyn closely monitored your relationship with your girlfriends. She knew when you two started fucking based on how your girlfriend replied when she asked, 'How was last night?' Kaitlyn would spend hours discussing with me the body language and word choices of your current girlfriend and your prior girlfriends. Your girlfriends' smiles always got really big after you started fucking; and after you broke up with them, their smiles were never as big with their later boyfriends."

Joanna liked to tease, but this was not a topic that was appropriate to tease about. She had me flustered and angry. I tried to shut down her teasing by saying, "You're lying."

Joanna shook her head and crossed her heart with her left hand while continuing to hold my cock with her right. "God's truth." She stroked my cock, which was now semi-hard. She smiled and looked at my cock. "Well, hello there." Even though I was flustered, I could feel my excitement rising. "You were soft until we started talking about your sister."
I felt even more flustered. "Just my natural recovery."

Joanna stroked my cock until I was hard, then she gave me her knowing smile again. "I think I know why it's so important to Kaitlyn that we fuck. She sees me as her surrogate, and this summer is the one chance for her surrogate to fuck you."

"That's bullshit, Joanna."

Joanna laughed mockingly. Then she surprised me by lying face down on the bed while hiking her ass up into doggie-style position. She looked back at me, gave me her knowing smile and said, "Fuck me, Brandon. Make your sister happy yet jealous."

I pounded Joanna hard and fast. I didn't enjoy fucking her like I normally did as I couldn't focus very well. When we were done, I said, "Please don't tease me about Kaitlyn again, okay?" It wasn't a suggestion.

Joanna put her hand softly on my chest and said contritely, "I'm sorry, Brandon. I went too far. Kaitlyn likes me teasing her about you, and I thought you might be the same."

I felt my anger melting. "I'm not."

I was lying on my back on the bed, and Joanna was lying on her side facing me. She leaned forward and kissed me lightly on the cheek. It was a soft kiss filled with affection. At the same time, she pressed her tits into me, stirring up my lust for her.

Joanna said softly, "I know I should promise to not tease you again about Kaitlyn."

When the promise didn't come, I said, "But you're not going to."

Joanna said huskily, "I don't know if my having you as my boyfriend makes Kaitlyn jealous, but it excites me to think it does." Joanna gave me a kiss filled with the promise of lots of hot sex. "You want me to get excited, don't you?"

I decided I had overreacted. If a harmless fantasy got her excited, I'd be stupid to put an end to it. "Yes, I want you to get excited."

Joanna gave me another long, soft kiss. "So it's okay if I tease you a little about Kaitlyn?"

I turned my head as Joanna moved to give me another kiss, so we'd kiss on the lips. She was such a good kisser; she knew how to use timing and pressure to communicate so much. I surrendered. "A little's okay."

"When I tease you about Kaitlyn, I'll be sure to make it up to you." Then she kissed me on the lips while pressing her naked body against mine.

* * * *

Saturday morning of our week at the lake was my first extended time with Paul, and he seemed very much the great guy Kaitlyn described. Mom got us up at six and, while Kaitlyn, Joanna, and I were yawning and slow to move around, Paul was hauling out to our minivan whatever he could find that was ready to go. When there wasn't anything to haul out, he was asking my mom what else he could do. Once we left home, we stopped at a gas station to fill up and grab a quick, hot breakfast, and Paul insisted on paying for everything.

In the minivan, Dad and Mom were in the driver and passenger seats. Paul was behind Dad and started playing on his tablet once we left the gas station. Kaitlyn was behind Mom. The third row of seats could be folded up or down and we had the right two-thirds as a bench seat. That's were Joanna and I were, snuggled together with my left arm draped across her shoulder. I had a warm, contented feeling. Joanna and I had had a great time Wednesday night, chatting with Kaitlyn and my parents while watching a DVD. After we had retreated to my bedroom, we had spent a lot of time kissing and talking quietly, did a quiet 69 and then cuddled naked until we fell asleep. Last night was also wonderful.

Kaitlyn turned and looked at Joanna, then used eyebrow raises and lip movements to apparently ask why Joanna and I hadn't fucked last night. I watched Joanna use similar facial movements to blame me for not consummating our relationship in our house. The truth was that Joanna had been the one who had wanted to do only oral, and the thought of pulling yet another one on her best friend had fired her up to give me the most pleasure possible without making much noise. I had been quite satisfied with being sucked off twice.

After I thought Joanna had had enough fun silently teasing Kaitlyn, I said, "I got hit by a golf ball yesterday at work."

Kaitlyn asked, "You did? Were you standing in a fairway?"

"No! I was in the trees, spraying herbicide on poison ivy. I was spraying away when suddenly I was whacked in the back just below my right shoulder blade."

Kaitlyn showed her compassion for her big brother by laughing at my pain. "That sounds like it hurt."

"It did! I did the man-that-hurts-like-hell dance for a few minutes then this golfer called to me, 'Have you seen a Titleist number five ball around?' It had been his ball that hit me. I wanted to throw the damn thing at him. I hope he got poison ivy from it."

I loved my job, except for the golfers.

Joanna, Kaitlyn, and I talked as Dad drove on and on. At one point, Joanna said, "I'm kind of cold. Is there a blanket I could put over me?"

We kept a blanket in the minivan for such occasions. Kaitlyn gave it to Joanna, and she put it over her and most of me, tucking one end behind her left shoulder. Once the blanket was over her, Joanna grabbed my right hand and pulled it across to her. She slipped it under her t-shirt and pushed it upwards. She said quietly to me, "Help keep me warm, Brandon."

I knew what she wanted as Joanna hadn't worn a bra this morning. I looked over at Paul and he was totally engrossed in his game. Mom couldn't see us, and the blanket would probably prevent Dad from being able to see us in the rear-view mirror. Kaitlyn, on the other hand, would definitely know what I was doing. I raised my hand up and cupped Joanna's tit.

Joanna smiled at me and then said to Kaitlyn, "He's such a good boyfriend. I'm so glad you suggested we date this summer."

I glanced at Kaitlyn. She rolled her eyes and said, "I thought you'd have a good time together."

Joanna pushed her tit into my hand and said, "We have a great time together."

For the next twenty minutes, I felt up Joanna while she talked with Kaitlyn. I put my head on her shoulder and slumped against her, so hopefully it looked to Dad like I was snoozing while leaning against her. I didn't feel very guilty about what I was doing as Kaitlyn had wanted Joanna and me to do this when she had driven us back to Joanna's apartment after tennis. When I finally stopped, Joanna gave me a kiss, and then turned to Kaitlyn. "He listens so well to me." Kaitlyn rolled her eyes but didn't say anything.

The three of us kept talking until Paul suddenly stretched. He announced to no one in particular, "Out of energy". He turned to Kaitlyn and said, "How you doin', Babe?"

"Doin' fine. Been talking with Joanna and Brandon."

Paul asked my dad, "How much further?"

"About an hour."

"Oh, Okay. Joanna, trade places with me please?"

Somehow, Joanna and Paul managed to swap spots in our cramped minivan. Paul had a hold of his tablet. "Let me show you Total Galactic War."

Paul walked me through all the features of it. He was a leader of one of the top alliances in the game, with members all over the world. He showed me screen after screen, with lots of detailed statistics about units and buildings. He discussed strategy and tactics with me. He showed me videos of battles he had fought. The back seat had been cozy for Joanna and me, and now I felt like Paul was practically sitting on my lap. Paul was oblivious to my discomfort and lack of interest. I occasionally sneaked a peek at Kaitlyn, and she'd silently laugh and roll her eyes. Paul talked enthusiastically about the game all the way to the lake house. I had never been so thankful to reach it.

* * * *

After lunch, the six of us went out in the ski boat. Dad drove and Mom was in the seat next to him. Behind those two seats were two benches. Joanna and I were on one bench, and we were facing Kaitlyn and Paul on the other. The boat was twenty-some years old and didn't have the wakeboarding hardware that newer boats had, but it was great for water skiing. As we raced across to Dad's favorite place to ski, I couldn't help checking out my sister. She was wearing a very sexy bikini; the top was purple, and the cups had a slanting cut that showed quite a bit of boob flesh. The top also looked like it compressed Kaitlyn's boobs upwards like a push-up bra. The bikini bottoms were black and low cut with a single wide purple band across the top. It looked expensive to me. I tried not to look at her, but there wasn't much else to look at.

Finally, to cover my checking her out, I asked, "That bikini. What's the material?" I had to yell to be heard over the wind and the engine.

"Neoprene," yelled back Kaitlyn. "It's specially designed for water skiing."

Paul yelled, "I bought it for her." His arm was around Kaitlyn's shoulders possessively. "I like to buy her things she looks sexy in."

I looked over at Mom and Dad as I wasn't sure how they'd react to Paul's announcement. They were facing forward, scanning the water in front of us. I guessed they couldn't make out what we were saying over the wind and the engine roar.

Joanna yelled, "He buys her lingerie."

A surprised look came over Paul's face before nodding in agreement. "I buy her something every Sunday night when I get home and have it sent to her. Then I spend the week imagining how good she'll look in it." A lustful, goofy grin crossed his face.

Joanna replied, "She gives us girls at the office a fashion show every Friday."

Paul laughed while Kaitlyn blushed. "She does?"

"Yes. She unbuttons her blouse, opens it up and shows off the top half. Then she describes the bottom half."

Paul looked at Kaitlyn, and she gave a small shrug, admitting to it. Paul said, "You never told me." Kaitlyn talked quietly to Paul for a few moments. He grinned hugely and squeezed Kaitlyn. He basked for a few minutes in the glow of Kaitlyn showing off his lingerie purchases to her co-workers.

Paul leaned forward and yelled to me, "You should buy Joanna some lingerie. Expensive, sexy stuff. Then she'll fuck you."

Kaitlyn whacked Paul and pulled him back. Paul looked at her and saw she was angry. She clearly felt Paul's last comment was over the line.

And it was. I wasn't going to buy Joanna expensive lingerie. I didn't have that kind of money. I had never bought any of my girlfriends lingerie. A shirt or sweater for Christmas or her birthday, yes. Lingerie or bikinis, no.

I looked at Joanna. She had an unreadable look on her face. Did she want me to buy her lingerie? Was that why she had brought up Kaitlyn's fashion shows? Bringing them up had made Paul a very happy man.

Kaitlyn whacking Paul hadn't been the act of someone in love. She hadn't acted lovey-dovey with Paul at all today. She had acted instead like someone on the downside of their relationship, still caring but very much aware of the other's faults.

* * * *

We spent the day skiing. My family were all excellent water skiers. Joanna had come to the lake several times and had gotten pretty good. Paul hadn't skied much so he was the least skilled. However, he took every fall with good humor and enjoyed skiing as much as the rest of us. When Mom or Dad skied, I steered the boat while Kaitlyn was the lookout. Dad had two rules about water skiing: no alcohol when going out on the water and always having a lookout as the driver had to continuously scan the lake for other watercraft. Sadly, far too many other ski boats were driven by incredibly self-absorbed, obnoxious, and rude jerks. And far too many people were buzzed while operating high-speed watercraft.

Around six, we arrived back at the lake house. My grandfather had bought this land when my dad was a young boy, and the place where he had wanted the lake house would get covered by the lake whenever there was an exceptionally heavy rainy season. So Grandpa had the lake house built on stilts. The ground level was a covered staircase that led to the lake house proper. The staircase landing was a mudroom with a washer and a dryer and was where we stored the stuff from the boat. The second floor had an open area for the living room, dining room, and kitchen. Four doors went off from the living room to the three bedrooms and the only bathroom. A deck wrapped around three sides of the living area, and a grill was on the deck right outside the kitchen. The view of the lake from the deck was spectacular.

Once we were all upstairs, Dad said to Paul, "Our tradition is the men cook dinner, and the women clean up; then the women cook breakfast, and the men clean up."

Paul said, "I don't know anything about cooking. I'd be no help to you." He picked up his tablet.

Dad said, "You can help me with the grilling."

"I don't know anything about grilling. I'd be useless. Could we have dinner delivered?"

Dad chuckled. It was a forced chuckle to cover his rising anger. "We're out in the boonies. Nobody delivers out here. Besides, we've already bought the food."

Paul said, "I'm a big guy and all I'd do is get in your way. I know you're willing to try to teach me, but I'm not going to be a good student because I don't want to learn how to cook. My dad and I never cook. I'm sorry."

Paul turned on his tablet while plunking down on the couch. Dad's face was bright red and I was afraid he was about to say something ugly.

Joanna rushed over to Dad, put her arm around him, and said soothingly, "It's the same way at my house. My mom never cooks. All she taught me was how to microwave." Joanna looked at Mom. "You've taught me everything I know about cooking." Mom beamed at the compliment.

Kaitlyn went to the other side of Dad and hugged him. She said, "I'll help," in an obvious attempt to defuse the situation.

I said to Kaitlyn, "Don't worry about it. Dad and I can handle it." I turned to Dad. "We're a good team, aren't we?"

Dad had swallowed his anger by now. He smiled and said, "Yes we are, Son."

* * * *

While Dad and I prepared dinner, the women took turns showering. Dad and I grilled up bacon-wrapped filet mignon and some veggies. It tasted great, but the dinners always tasted great at the lake house. After dinner, the men took turns showering while the women cleaned up. Once that was all done, we sat on the deck and talked while watching Joanna braid Kaitlyn's hair. Joanna had been braiding Kaitlyn's hair for almost as long as they had been friends. She had said Kaitlyn had the perfect hair for braiding. Ironically, Joanna preferred to have her hair down most of the time, so Kaitlyn rarely had a chance to return the favor. Joanna spent a lot of time shaping and teasing Kaitlyn's hair into the right condition, and then her hands were a blur as she weaved the hair into a braid. Kaitlyn turned around and showed off the braid.

Paul was stunned by Joanna's hair-weaving magic. He stood up to admire it. "That's amazing! It looks so beautiful, and you did it so fast! I've never seen anything like that before." He looked at Kaitlyn. "Your hair looks fantastic."

I knew this style was called a Dutch braid as the braided part of Kaitlyn's hair stood on top of the rest of her hair, which was pulled tight in the back. Joanna knew many different ways of braiding Kaitlyn's hair, and my favorite was when she'd make braids all around Kaitlyn's head, so the braids looked like a crown.

Kaitlyn smiled happily before looking at Joanna appreciatively. Joanna looked down, embarrassed by all the praise.

I said, "In Ohio, Joanna would have to attend beauty school for 450 hours before she could get a job braiding hair."

"450 hours?" Paul asked incredulously.

"Yeah. Becoming a cop requires 580 hours of training. Ohio is a lot more worried about bad hair-braiders than bad cops."

* * * *

At nine, Mom and Dad said, "Have fun kids" and left for a walk. Based on prior years, they'd be back at ten, and they'd expect us to be in bed then. Once they were back, we were to do nothing more than quietly cuddle and kiss.

As soon as the door closed, Kaitlyn took Paul's hand and led him to their bedroom. I smiled at Joanna, took her hand and led her to our bedroom. Joanna and I stripped off our clothes. Joanna laid out a nightshirt to wear later. We lay down on the bed and kissed softly while running our hands over each other's bodies. I pushed my tongue forward and Joanna opened her mouth to receive it. I brought my hand to her tit...

...when Kaitlyn started making loud "Oh!" sounds. The walls were thin, and it sounded almost like she was in the same room as us. The sound of my sister moaning her pleasure broke the mood for me. I continued with the kisses and strokes, but the constant "Oh! Oh! Oh!" kept distracting me and I couldn't get into it. Finally, I gave up and said, "Let's go to the couch. We'll be more comfortable there."

Joanna said, "Your sister is going to be pissed we aren't making noises like they are."

I sat up, grabbed my underwear, and tossed Joanna her panties and nightshirt. As I pulled on my shorts, I said, "Pissing off sisters is a part of the job description of a brother."

I led Joanna to the couch and had her lean against me. I slowly kissed her shoulders. Kaitlyn stopped moaning, and I started getting back in the mood. Then the thumping began. Thump! Thump! Thump! And of course, Kaitlyn oh'ed in time with the thumps. Joanna rolled her eyes at the thumping sound. It was so damn embarrassing; I felt embarrassed for Kaitlyn and Paul. The thumping sound lasted several minutes and once it was done, I whispered to Joanna, "We're not doing anything tonight. I'll get us some privacy tomorrow." Joanna moved her head slightly up and down in a sign that I took to be more disappointment than agreement.

I pulled her into a hug and wrapped my arms around her. "I'll make it up to you tomorrow, I promise." I gave Joanna a light squeeze.

That was when I heard the door open. I turned to see Kaitlyn in a nightshirt stomp over to in front of us. "What the hell are you two doing?"

I said, "Ummm..."

"Or more correctly, why aren't you doing what you should be doing?"

"You two were so loud..."

"What the hell!" Kaitlyn's eyes blazed. "We were fucking! Did you expect us to fuck quietly!"

Joanna wasn't saying a word and was looking off into space. I said, "Well, no but..."

"You knew Paul and I fucked, right? You've heard us fuck back at our house, right?"

"It wasn't nearly as loud there."

"Well, we're not fucking now. You and Joanna have thirty minutes before Mom and Dad get back."

I liked to go slow and I wasn't sure we'd be done in thirty minutes. I didn't want to rush through our first lovemaking session at the lake house. "I'm not in the mood now."

"MEN!" Kaitlyn yelled and then stomped off to her bedroom, slamming the door.

Joanna said, "I told you she'd be pissed."

I chuckled. "You did. You know Kaitlyn well." I shook my head in frustration and disbelief. This was the first time Kaitlyn had brought a guy to the lake house. In the past, she had gone on the walk with Mom and Dad. I hadn't considered the privacy issues of both couples wanting to make love at the same time.

I decided to do what I could to salvage the evening. I put my arm around Joanna, and we kissed gently for a while. I said quietly, "You were very naughty this morning in the minivan." Joanna's eyes lit up and she chuckled. "Were you teasing Kaitlyn?"

"Yes. Thanks for going along. It got me soooo excited."

I felt bad again. "I'm sorry, Jo--"

"Hey! Hey! It's okay. If you're not in the mood, you're not in the mood. I don't want you to force anything. There'll be nights when I'm not in the mood, and I know you'll respect that."

"Thanks, Joanna."

"I really like that you don't pressure me, that it's always my choice to have sex and not my duty. I wish my other boyfriends had been that way."

I smiled. "So, you like having me as your boyfriend?"

There was a pause, and then Joanna said, "I like dating you." I was disappointed that Joanna hadn't embraced having me as her boyfriend. But before I could get upset, Joanna distracted me by raising her hand to my head. She said, "I really like your hair," as she ran her fingers through my dark brown hair. "It's a good length and I like how you get it cut." She moved her hand down and started running a finger over my eyebrows. "And I like your eyebrows. They're a good size and shape."
"I want to grow a unibrow, but my eyebrow follicles keep not cooperating."

Joanna snorted, and then started making circles around each of my eyes with her finger. "You have beautiful eyes." My eyes were blue like Kaitlyn's, but not quite as brilliant.

"Thanks."

Joanna started rubbing my nose with her finger. "I like your nose. It's not too big or too small."

"The best nose is the one you don't notice." That earned a little grin.

Joanna started circling around my lips with her finger. "I really like your smile. It's a handsome smile, and I like that you smile a lot. And I like that you say a lot of fun things. Sometimes silly, sometimes funny." Joanna dropped her finger, so it made circles around my heart. "And I like that you make me feel like I'm a lot of fun to be with."

"You are a lot of fun to be with. If I had known how much fun you'd be to date, I would have started dating you long ago."

Joanna leaned in for a kiss. When we were done kissing, she said, "Tomorrow, get us some privacy so we can have some fun."

* * * *

I didn't sleep well that night because I was angry at Kaitlyn and her antics. It was none of her damn business what Joanna and I did. And I was angry at Joanna for hiding the fact that we were lovers from Kaitlyn, which had prompted her antics. Finally, I was angry at myself. If I had been able to ignore the sounds of Paul and Kaitlyn having sex, then the hiding would be over, and Kaitlyn would have been happy instead of pissed. I was the person mostly at fault for how things had turned out. I decided on a plan to make things right -- during the next afternoon session, Joanna and I would stay in the lake house while everyone else went out on the lake.

I groaned when I heard the knock on our door. It was 6:30, time for Joanna to get up and help make breakfast. She threw on her nightshirt and slipped out. I dozed off, to be awakened a little later by the announcement that breakfast was ready.

When breakfast was over, I was concerned Paul would balk at helping to clean up, but it was quite the opposite -- he cleared the table all by himself and loaded everything close to the dishwasher into it. Of the four young adults, he was the only one in a good mood.

While we were changing into our swimwear, a front started coming in. No rain had been in the forecast when we had checked yesterday morning, but it sure looked like rain was coming now. The wind blew hard, black clouds rolled in, lightning flashed, thunder boomed, and rain began to fall in buckets.

The lake house wasn't a lot of fun when it rained. We had satellite, a game system and a number of DVD's, but sitting around got old after a few hours. Normally when it rained, we'd go shopping at the wide spot in the road that was the nearest town, but, as we had arrived yesterday, there wasn't anything to shop for.

Another downside of the rain was that any idea of Joanna and I getting some private time went out the window. I felt rotten about having to break a promise, and Joanna didn't seem too happy with me when I told her I wouldn't be making it up to her today.

After lunch, Mom and Dad took their traditional nap. On non-rain days, Mom and Dad kicked us out of the lake house so they could "nap better". When we were kids, we'd go to a nearby lake house and play with other kids. When I was fourteen, I realized nap time was when Mom and Dad made love. When it rained like today, Mom and Dad still took a nap but made no noises and told us to be quiet.

When Mom and Dad went to their bedroom, Paul went to his bedroom and closed the door. Kaitlyn turned to Joanna and said, "Let's go to your bedroom and talk."

I asked, "About what?"

Joanna said, "Girl talk," as she was already moving toward our bedroom.

I sighed. "Let me get something to read first." I grabbed an old novel I kept in my bedroom and read it on the couch for the next hour.

* * * *

When Mom and Dad got up, I played video games with Paul and Kaitlyn while Joanna read a novel. When we finished one game, I asked, "Anyone interested in going for a walk in the rain?"

Joanna said, "If you don't mind, I'd prefer to keep reading."

Kaitlyn said, "I'll go."

No one else was interested, so Kaitlyn and I went. It was a warm rain, so Kaitlyn and I wore swimwear, and each of us carried an umbrella. We wandered along the lake shore and talked about different memories of prior trips to the lake. Then Kaitlyn asked me, "How are things between you and Joanna?"

"Good."

Kaitlyn gave me a 'don't-give-me-that-shit' look. "Care to expand on that?"

"Not really."

We walked for a bit more. Then Kaitlyn said, "Please."

"Please what?"

"Please tell me more about what's going on between you and Joanna. She's my best friend, I think your dating her is really good for her, and I want to know more about how it's working out."

I sighed. I wanted to tell Kaitlyn that it was none of her business, but Joanna was her business. "I'll make you a deal. I'll tell you more about Joanna and me if you tell me what your girl talk with Joanna was about."

"A deal?" asked Kaitlyn disgustedly. "You want to make a deal?"

I gave her a little smirk. "I do."

"Oh, okay," she said resignedly. Then added, "It was about our plans for tonight."

"Which are?"

Kaitlyn didn't reply for a while, and then said, "Offer me another deal."

I chuckled before wondering what the plans could be. "How about this; I'll tell you more about Joanna and me if you tell me why you and Joanna are such great friends."

"Okay, but only if you go first!"

I laughed. I never knew how seriously to take what I considered to be Kaitlyn's overreactions. I suspected she was quite fine with the second deal but didn't want to show it.

I said, "When you're not around, I've been trying to convince Joanna to relax, to be the way she wants to be and do what she wants to do. I think she's been afraid that if she does something wrong, I'll get upset and break up with her. I feel like I'm finally starting to see the real Joanna and she's a lot of fun. Very unpredictable, in a good way. Very impish, but not in a bad way. I'm very happy you talked me into going out with her. I'm not sure what will happen long term. Your turn."

"Okay. Joanna and I are such great friends because we always support each other and never judge each other." Kaitlyn sighed. "So many people dump on her because of her failed relationships. I'm the opposite -- every time she's started dating someone, I've been supportive of her choice, and I've tried to give her advice on how to make it work. Every time she's broken up with a guy, I've said you did your best, learn from it and move on."

"Why?"

"Why?" Kaitlyn countered in surprise.

"How can you keep being supportive of her when she keeps making the same mistakes?"

"Well, it's..." A big sigh. "I'm the same way. I'm drawn to guys I can easily manipulate, even though I lose all respect for them once I manipulate them. I keep saying I'll date better, but I don't. I'm an awful person."

I laughed, and then I realized that Kaitlyn was being serious. "You're not an awful person. You're a very caring person."

Another long sigh. "Thanks for saying that. I do care. I want the people around me to be happy. I'd do anything to help Joanna be happy. It's just that...I try too hard at times. Like last night -- I shouldn't have blown up at you. I'm sorry I did. Joanna is so much happier and self-confident now because of how you treat her. You two are going in the right direction, but I can't resist the urge to push you two along."

"So after lunch, you asked Joanna to have a talk, and then you and Joanna came up with a plan for getting me to make love to her tonight?"

Kaitlyn sighed. "Yeah. Stupid, right? I should just leave well enough alone. But I can't. It's too important to me." She added pleadingly, "Please go along. It'll be a lot of fun, and I think it'll be a wonderful experience for my best friend."

I was going to go along. After last night's fiasco, I was ready for Joanna to take charge, even if Kaitlyn was prompting her on what to do. But I couldn't admit that to my sister. Instead, I gave a half-shrug. "We'll see what happens."

"You're such a shit at times," Kaitlyn said, in an almost respectful tone.

I decided to change the subject. "Let's head back."

"Okay."

We were quiet for a little bit. I said, "I hope your plan for tonight doesn't involve me feeling up Joanna in front of you. Didn't that bother you?"

Kaitlyn shook her head. "If it had been anyone else, I would have told them they were behaving inappropriately. But because it was Joanna, I went along with it and embraced that she was having fun at my expense."

I smiled at the memory. "It was fun."

"I don't judge her, and she doesn't judge me. It's great having a friend who doesn't judge me. I've told her things that would freak out anyone else..." Was she thinking about all the hours she had spent discussing me? "...but she accepts that that's the way I am. She teases me about those things, and I like that she teases me because it tells me she really does accept me as I am."

That fit everything I had seen of the two of them. Then something struck me from what she had said. "Do you manipulate Paul?"

"If I tell you, will you promise to go along with the plan for tonight?"

I laughed again. "I promise to do whatever Joanna and I enthusiastically agree to do."

"Again, you're such a shit." The way she said it made it almost sound like a compliment. "He's not easy for me to manipulate. The things I'd typically manipulate a guy for -- fancy dinners, clothes, lingerie -- Paul gives to me openhandedly just for being his girlfriend. He's happy being a big nerd who loves his toys and his game; and he's not open to changing. I respect him for standing his ground with me. He's very much a stereotypical guy in that as long as we have sex regularly, he's thrilled to have me as his girlfriend. But I don't consider having sex with him manipulating him as we both enjoy it a lot. He's not the most socially aware guy, and he'll occasionally say something really stupid, but, like me, he wants the people around him to be happy, and he'll do what he can to make them happy. What he thinks to do is spend money as he has so much."

"So you're happy with Paul?"

"I didn't say that," Kaitlyn said sharply. "I like that I can't manipulate Paul. It keeps me from doing destructive behavior. I don't like that I can't manipulate Paul because he's bullheaded."

Kaitlyn was sounding down on herself again. "You don't manipulate me."

"Only because you're so hard to manipulate. I tried to think of ways to manipulate you into going out with Joanna, but I struck out. I finally basically begged you to do it. You've been driving me crazy all summer because you keep ignoring my advice and have gone so slow with Joanna. I want her to experience what having a caring lover is like." Her concern for Joanna was touching. "Trying to push you into doing something is like trying to push a brick wall." I laughed. "I wished I could date a guy like you, who I can't manipulate because he's got great principles and sticks to them."

That was a punch to the gut. A long silence followed. I didn't know what to say. After a while, Kaitlyn said, "Thanks for dating Joanna. And thanks for inviting me to go along with you two. It's been a lot of fun. You're a really good person, Brandon."

The way Kaitlyn said that, I felt like she was crushing on me. Joanna had told me that Kaitlyn had the hots for me. I had never gotten that vibe from her before, but I was getting it now.

I'm being stupid. Kaitlyn had a boyfriend, and she was doing her best to set me up with her best friend. I was her brother. I wasn't even on her radar.

The ensuing silence and her comments pushed me to consider some uncomfortable thoughts. Did I think of Kaitlyn in non-brotherly ways? Did I have something of a crush on her?

I respected Kaitlyn. She was smart, competent, and effective. She enjoyed teasing and being teased. She never got too bent out of shape and forgave things as soon as I said I was sorry. She knew how to keep private what should be private. Unlike most brothers, I felt like I could let down my guard around her and just have fun. So many of the girls I had dated had seemed shallow compared to her. If I had met someone like Kaitlyn at college, I would have definitely asked her out.

But she was my sister. And that was that.

* * * *

The rain let up in time for us to grill dinner outside. While Dad and I were prepping the food, Paul came into the kitchen and said, "Sorry about yesterday. I'd be useless in the kitchen, but I know how to do laundry, so I'll do all the laundry. I'd just get in your way here." Then he left the kitchen and joined the girls.

A little while later while Dad and I were out at the grill, Kaitlyn came out and joined us. She said, "I apologize for Paul. I didn't know he'd do this."

Dad said, "I'm disappointed he's not willing to try to learn how to cook. Your mom and I think everyone should learn how to cook."

Kaitlyn sighed. "It's not about learning how to cook. He'd be fine learning how to cook. It's about his game. He gets a certain amount of energy per hour and after several hours, his energy reaches capacity, and he stops getting more. When he gets in from skiing, he wants to play his game. He chose to do the laundry instead of helping with cooking because it fits his gaming schedule." Kaitlyn looked very unhappy. "Do you want me to help out with dinner from now on?"

I said, "Don't worry about it. Dad and I have everything under control." Dad nodded his head in agreement. I preferred taking on Paul's responsibilities to shifting them to Kaitlyn, and Dad seemed to be of the same mind.

* * * *

When Mom and Dad left for their walk, Kaitlyn and Joanna immediately stood up. We had been playing a video game before Mom and Dad left and were seated around the coffee table. Kaitlyn went to the dining table and turned one of the dining chairs, so it faced the living room area. She said to Paul, "Come sit here."

Paul looked at me, shrugged, and went over to Kaitlyn.

In the meantime, Joanna had one of the high-back chairs in the living area turned so it was facing Kaitlyn's chair. It was like the dining chairs except it had a padded seat. She said to me, "Come sit here."

I snorted. "Yes, boss."

Once I was seated, Kaitlyn said, "Stay there, boys. We'll be back shortly." Then she and Joanna went into Kaitlyn's bedroom.

Paul said, "They're planning something."

No shit, Sherlock. "I have no idea what."

Paul raised his beer and said, "Well, hopefully, I can finish my beer first."

As there hadn't been much to do today, we had been drinking steadily all day, and all four of us were feeling no pain. Paul and I sipped our beers and waited. He and I were dressed as the men always dressed in the evening at the lake house -- t-shirt, shorts and no footwear.

I heard the bedroom door open, I turned toward it and my breath was taken away. Kaitlyn sauntered out wearing only a bright purple lacy bra and matching panties. They provided a great contrast to her pale skin and emphasized her wonderful curves. Her honey-brown hair was braided down the right side of her head and ended in a wide braid that rested on her right shoulder. Paul whistled at her as she entered the space between Paul and me.

Behind Kaitlyn was Joanna in a yellow lacy bra and light-yellow panties. She didn't look nearly as amazing as Kaitlyn, since the bra didn't match her panties. Also, the bra was the better-endowed Kaitlyn's, and, as Joanna's tits didn't fill the cups, it emphasized she was less endowed. Still, the yellow bra looked great against her light olive skin. It was a hot little fashion show the two girls were giving us.

When Joanna caught up to Kaitlyn, she turned and came over to me while Kaitlyn walked toward Paul. I couldn't help checking out Kaitlyn's nicely rounded ass as she made the walk. When Joanna reached me, she sat down on my lap and gave me a kiss. I kissed her back. As we continued kissing, I could hear the sounds of Kaitlyn and Paul kissing in the background. Knowing they could hear Joanna and me kiss made kissing her even hotter than normal.

Kaitlyn called over, "Joanna, do this!" Joanna and I turned to watch. Kaitlyn kissed Paul aggressively, ramming her tongue into his mouth. Kaitlyn moaned loudly as their tongues dueled.

Joanna grabbed my chin, turned my face toward her, and lowered her mouth toward mine. I opened my mouth and happily accepted her tongue. My head spun as we Frenched to the sounds of Kaitlyn and Paul's slurping. Clearly, we were following the plan Joanna and Kaitlyn had come up with this afternoon. I found the mutual make-out session insanely hot -- my cock was rock hard in my shorts. What more did they have planned?

Joanna ended our kiss and turned toward Kaitlyn and Paul. My gaze followed hers. Paul's hands were covering Kaitlyn's tits and squeezing them through her bra. Joanna grabbed my hands and lifted them toward her tits. I cupped them, feeling their weight through the silky lace of Kaitlyn's bra. Joanna resumed kissing me.

It took me a moment to realize what I was doing -- I was squeezing my girlfriend's tits in front of my sister and her boyfriend. The alcohol had me addled. I was enjoying the mutual make-out session, but groping Joanna was a little more than I wanted to do in front of Paul and Kaitlyn. Then I had an idea.

While I kissed Joanna, I pushed her off my lap and guided her to sit down. I broke the kiss to move behind her. Once I was behind her, I moved her hair out of the way and lightly kissed her neck. I slowly kissed down her neck, adding occasional nibbles. I continued across her shoulder. When I reached the bra strap, I looked across the room.

I was surprised to see Kaitlyn looking at me with her mouth open. She was holding Paul's hands in her lap. Kaitlyn said, "That looks wonderful."

Joanna said sultrily, "Oh, it is. Each little kiss gives me a shiver. He's got me so hot."

Kaitlyn turned toward Paul. "Would you do that please?"

A look of horror came across Paul's face. "I don't know how."

Kaitlyn said, "You need to learn." Her tone spoke of frustration with Paul.

Joanna said, "Brandon, kiss the rest of my shoulder."

I resumed kissing along the top of Joanna's shoulder, going extra far before stopping. I looked back over at Kaitlyn and Paul. Joanna said, "Paul, your turn."

Paul said defensively, "I...I...I--"

"Let's trade places, Kaitlyn," Joanna said as she stood up. "Paul, you can watch what Brandon does and learn."

Paul's refusal to try to kiss Kaitlyn's neck and shoulder had ruined the mood. Kaitlyn gave me a nervous smile as she crossed the room. I smiled back and couldn't help but notice how fine she looked in her purple bra and panties. I looked across the room and saw that Joanna was sitting on Paul's lap. I expected Paul to complain, but he seemed resigned to being given a lesson. I didn't want to kiss and nibble on my sister as I had done with Joanna, but I felt like I had to or the mood would stay ruined.

Kaitlyn's braid already had her hair out of the way. I leaned forward and kissed her neck softly. Kaitlyn gasped. I felt like there had been almost a spark of electricity between us. I moved a little and softly kissed again. Another gasp. I moved a bit further down and lightly nibbled. Kaitlyn gasped louder than the first time I had kissed her. This was so fucking hot -- kissing my sister like this in front of her boyfriend and my girlfriend. With every kiss, I expected a shout of "That's enough!" but none came.

I put my hands on Kaitlyn's upper arms to balance myself as I continued to kiss and nibble. Her skin felt good in my hands. I loved Kaitlyn's smell; it was the same shampoo that Joanna had used that evening, but it smelled better on Kaitlyn. Kaitlyn's breath was very ragged. I had given neck nibbles to several girls, and none had reacted this strongly. I had gotten the vibe during our walk that Kaitlyn had the hots for me. The vibe was now much stronger as she was definitely getting off to my kisses. I was amazingly hard. I was glad the chair blocked my hard-on from Joanna's view.
By the time I reached the bra strap, I could smell Kaitlyn's excitement. It made me realize how far over the line was what I had done. I stopped immediately and looked across the room. Joanna had a smile on her face and seemed to be laughing lightly. Paul was holding her lightly and seemed to be talking to her instead of trying to learn what I was doing.

Kaitlyn shot up out of the chair and said loudly to Paul, "Let's go to our bedroom. Now." She held out her hand for Paul. Paul gave her an eager smile as he quickly crossed the room to her. They walked into their bedroom and slammed the door.

I saw movement and turned to see Joanna throw a towel over the couch. The bra was gone, and she quickly slipped off her panties. She lay down on the couch and said, "Eat me, Brandon."

I lay chest-down on the couch in front of Joanna as she spread her legs wide. I worked my tongue up and down her slit, getting her warmed up. Then I heard the first "Oh!" from Kaitlyn. Joanna put her hands on the side of my head and said, "Keep going, Brandon."

I did. I was so horny that I was definitely not going to stop. I was going to fuck Joanna as soon as I made her cum. I was going to give her a pounding tonight.

I danced my tongue up and down beside her clit. Joanna quietly gasped her pleasure. I adjusted the timing of my licks, so she gasped at the same time as Kaitlyn. Kaitlyn's loud moans came clearly through the wall, so it was like I licked Joanna to pleasure Kaitlyn.

Kaitlyn's moans suddenly stopped. I kept on lapping Joanna's pussy, giving her clit special attention. I could hear her deep breaths now.

Thump! Kaitlyn and Paul were fucking now. Thump! Thump! Thump! I wanted to join them. I wanted to fuck Joanna silly. I continued working her clit until she quietly came. I could barely hear her over the sounds of Paul and Kaitlyn fucking.

When Joanna recovered, I climbed above her and guided my cock to her pussy. Normally, I let her guide me in, but tonight I wanted to fuck so bad that I guided myself to her hole. A push, a push, and a third push, and I was buried all the way in. Then I started fucking her hard, pounding her furiously. Now, I could shut out the sound of Kaitlyn and Paul fucking. I was totally focused on slamming into Joanna. I desperately needed to release the sexual tension by cumming in her. I fucked her like a dog fucks a bitch in heat until I exploded into her so hard that I saw stars.

When I was finished, I collapsed onto Joanna. She hugged me tight and laughed lightly in my ear. "So mine and Kaitlyn's plan worked for you?" She laughed some more. I joined in. As no sound of sex was coming from the other room, I could hear her clearly now.

I said, "So what exactly was your plan?"

"That reminds me," she said as she pushed on my chest to get me off of her. I pulled out of her and got off of the couch. She sat up and knocked three times on the wall to Kaitlyn's bedroom. Joanna looked at me and smiled. "That's the signal we fucked. We don't want Kaitlyn storming back out here."

I used a corner of the towel to clean the juices off my cock. Joanna took the towel in one hand and my hand in her other before leading me to our bedroom. I pulled back the covers and we got into bed. We lay on our sides facing each other. I stroked her face and said, "Your plan?"

"Oh, yeah! Well, I told Kaitlyn that last night they were so loud while we were in the middle of foreplay that it took you out of the mood. And I expected the same thing to happen tonight if we didn't do anything different. I suggested they slow down so we'd be the first ones to start having sex. Kaitlyn said she didn't think she could get Paul to slow down enough. So she came up with the idea of us doing foreplay together as a way of getting both couples on the same timeline. Once the foreplay was done, I was to have you eat me and then fuck right away." Joanna gave me a naughty grin. "The noise didn't seem to bother you this time."

"No, it didn't. If anything, it made the sex better for me. And for you?"

"The same. It was like they were cheering us on."

"How far were we supposed to go out there?"

"Kisses and feels. We were supposed to do lots of kissing, but Paul went almost right away for the feels." A concerned look came across her face. "Kaitlyn looked so sad as she watched you give me neck kisses. I hope you didn't mind me having you do the same for her."

"I was fine with it. It was Paul I was worried about. I was afraid he'd get angrily jealous even though I wasn't kissing Kaitlyn on the lips or feeling her up."

"Exactly! I kept telling Paul that while you were kissing Kaitlyn. He wanted to switch back and make out more, but Kaitlyn had other ideas."

I laughed. "She did. It was funny to hear her say 'Now' and to see Paul hustle to obey." We both laughed. I kissed Joanna and my feelings for her swelled. I was tempted to tell her that I loved her. With my other girlfriends, they had said, "I love you" before I was ready to say it. I wasn't certain Joanna was ready to hear me say it, so I didn't.

Instead, I made a circle around Joanna's tit and said, "I think we have time for another round."

"Oh no. Paul is a one-and-done guy and I promised Kaitlyn we wouldn't do a second round."

I arched my eyebrow. "Where was this consideration for the other couple last night?"

Joanna chuckled. "We didn't ask for any consideration then. Kaitlyn did today." Joanna moved close to me, pressing her body against mine as she kissed me sensually. "But I could suck you off if you promise to not make a sound."

* * * *

I didn't sleep well again. This time, I kept waking up to my mind replaying me kissing Kaitlyn. Once again, I felt the texture of her skin on my lips, and I heard her gasps. I was hard all night long.

* * * * Chapter 2 * * * *

To save me some comments and PM's: I've always heard people use "laying out" for sunning. It's apparently an American-only phrase. I know that's grammatically incorrect, but it's what sounds natural to me.

The next day, Monday, was beautiful for water skiing, and we had a great morning session. When Mom or Dad skied, Joanna sat next to me, and Kaitlyn taught her how to be a good lookout.

After lunch, it was nap time for Mom and Dad, which meant the rest of us had to hang out somewhere else for at least an hour. What Kaitlyn and I usually did was lay out on chaise lounges that were halfway between the lake house and the lake. While Mom and Dad cleaned up, Joanna and Kaitlyn went into their bedrooms to change into sunning bikinis. The difference in how busty Joanna and Kaitlyn were was even more obvious when they were in these bikinis. Still, Joanna looked good.

Once we left the lake house, Joanna, Kaitlyn, and I went to the chaise lounges while Paul went over to a hammock in the shade with his tablet. We sprayed sunscreen on each other and then lay down. As I hadn't slept well the last two nights, I was soon fast asleep.

"...to you?" I heard Kaitlyn say quietly.

"Oh, yes. He's done it a couple of times," Joanna replied, also quietly. It was like my subconscious had heard I was being discussed and had woken me up. I continued to act asleep. "The first time he did it was before we fucked for the first time."

Kaitlyn gasped. "You've been fucking?"

Joanna snickered quietly. I thought they were being quiet to not wake me. "For weeks."

"Slut! Why didn't you tell me?"

"Because it was so fun seeing you get bent out of shape. Consider it revenge for all the fashion shows at work."

"Revenge? Did my showing off what lingerie I was wearing bother you?"

"Hell yeah! 'See what expensive lingerie my boyfriend bought me this week.' You know I don't have anything like that. All my underwear I buy on sale at Wal-Mart."

"I should have known, Joanna. I'm sorry. Forgive me?"

"Sure. Forgive me?"

Kaitlyn laughed. "Sure. Even?"

"Even."

There was a pause. I started to drift back to sleep but perked up again when Kaitlyn said, "Did it bother you when Brandon kissed me?"

"No," said Joanna like it was obvious. "It was my suggestion."

"Would you...would you mind if he did it again tonight?"

I had conflicting feelings about kissing and nibbling on my sister. Part of me thought it was wrong, but it was easy to dismiss that as no one else had been upset about me doing it. What I eventually settled on that it was a stupid thing to have done, but I had done stupid things before and would do stupid things again, particularly after a few beers, so there was no point worrying about it.

Joanna asked, "What would Paul think of that?"

"After we had sex last night, he made a joke about me liking my brother kissing on me too much. I told him that he'd better hope that Brandon did it again as he wasn't putting me in the mood for sex."

"Ouch!"

Kaitlyn said in an angry hiss, "Yeah." Then her voice cooled. "Paul's not going to do anything that could result in him being cut off." She sighed. "And I don't want to cut him off as it'll ruin the vacation for everyone else. But I can't count on him to put me in the mood. He's not good with foreplay; he always wants to go straight to sex."

"And Brandon kissing on you certainly put you in the mood." Joanna cackled quietly. "So you want to do tonight like we did last night?"

"Yes."

"Last night was fun. I've never done anything like that before but would enjoy doing it again." Then in a teasing tone, "I'm okay with lending my awesome boyfriend to you for a few minutes."

"Thanks," said Kaitlyn gratefully. After a few moments, she added, "Brandon's been a good boyfriend for you."

"A good mercy boyfriend."

Kaitlyn sighed. "He's not doing anything with you because I've asked him to. He wouldn't make love to you unless he cares for you. He genuinely likes you, Joanna."

"Then why does he always go out with both of us instead of just me?" Because we all have more fun when it's all three of us, and Kaitlyn doesn't mind being a third wheel. "Why didn't he spend more money on me? Take me to nice restaurants? Buy me nice lingerie?" Because I'm a struggling college student working a minimum wage job. "Why did you keep pushing him to make love to me?"

After a long pause, Kaitlyn said in a pained tone, "Brandon doesn't spend lots of money on his girlfriends. He shows his affection in other ways. And you can tell he cares for you in the way he looks at you and pays attention to you. Every girlfriend he's had has enjoyed having him as a lover. I wanted you to have a very positive lovemaking experience." Kaitlyn's tone lightened up. "Am I your best friend or what?"

"You are my best friend," replied Joanna with warmth in her voice. "Have been for years."

The girls moved on to subjects I wasn't interested in. I was angered and frustrated that Joanna still considered me a mercy boyfriend. What did I have to do to convince her that I cared for her? I had been as loving and as affectionate with her as I had been with any other girlfriend. I was suddenly very glad I hadn't said "I love you" last night. She probably would have not returned it, which would have made things very awkward.

* * * *

In the afternoon, we went jet skiing. While Joanna and I were riding a two-person jet ski, she told me about Kaitlyn's request.

I said, "Aren't you bothered by me lightly making out with my sister?"

"No! It was my idea. It was harmless fun. Last night was a lot of harmless but very exciting fun. Kaitlyn and I want to do it again."

I felt it was a stupid thing to do, that we could wind up embarrassed about it. But having a group make-out party twice was no more embarrassing than doing it once. "Okay."

* * * *

After jet skiing, we had a wonderful dinner and an enjoyable post-dinner conversation. When Mom and Dad left, Kaitlyn said, "Chairs like last time" before she and Joanna disappeared into her bedroom. I felt apprehensive. Though I had enjoyed last night, I couldn't shake the feeling it had been wrong. I felt like tonight was going to be more wrong since we were sober, and I knew I was going to be lightly making out with my sister in front of my girlfriend and her boyfriend.

Paul said, "I wonder what they'll wear tonight."

I shrugged. I tried to convince myself that seeing Kaitlyn in a bra and panties was just like seeing her in a bikini, but I failed -- bra and panties felt forbidden, which made seeing her in them very exciting. Then I shook my head; we were going to have some harmless but exciting fun, just like Joanna said. No one would get angry; nothing to feel embarrassed about.

The door opened and I turned to see the girls come into the room. Joanna led this time, dressed in the same bra and panties as last time.

Paul said, "Nice. My favorites."

Once I got a good look at Kaitlyn, I could see why the bra and panties were his favorites. They were a dark blue which looked great against Kaitlyn's skin. The bra had a circle close to Kaitlyn's neck, a circle beneath her breasts and a clear mesh connecting the two circles that had a plunging 'V' in the middle. The mesh lightly held her breasts, and they shifted noticeably as she walked. The mesh had stars scattered across, two of which strategically covered Kaitlyn's nipples. I could see all of her tits except where the stars were. The panties had an inch-wide ribbon of silk across the top with lace beneath. Right in the middle, the lace was missing and instead there was a deep V that must end just above her pussy. Any doubts about whether Kaitlyn shaved were gone. She looked sexy as hell in her outfit. Kaitlyn knew how to strut her stuff, and she oozed sexuality as she sashayed.

When the girls reached the space between Paul and me, they again stopped for a moment before Joanna walked sultrily toward me as Kaitlyn did the same toward Paul. I smiled at Joanna. She did look sexy as she walked toward me, even if she was the moon to Kaitlyn's sun.

I was ready with a kiss when Joanna slipped into my lap. After our first kiss, Joanna moved forward and whispered into my ear, "Lots of kisses tonight" before kissing along my jawline back to my mouth.

I was happy to comply. I loved kissing her. She had soft, full lips that felt great against mine. After a few kisses, I heard Kaitlyn say, "Not yet, Paul". I tilted my head enough so I could look over and I saw Kaitlyn pulling Paul's hands down from her tits. I sympathized with Paul -- how could Kaitlyn expect him to keep his hands off her tits when she was wearing that bra?

I pushed Kaitlyn and Paul out of my mind and concentrated on kissing Joanna. We kept kissing on the lips, but in slightly different ways that made the kisses hotter and hotter. Sometimes she'd grab my bottom lip between her lips as I pulled away. Sometimes I did the same to her. Sometimes I'd run my tongue over her lip as soon as the kiss ended. The whole time we were kissing, I kept thinking of Kaitlyn and Paul doing the same thing on the other side of the room. I heard another, "Not yet, Paul", but I was so into kissing Joanna that I didn't look this time. She was more aggressive in her kisses tonight than normal, like kissing in front of Kaitlyn and Paul was getting her extra excited.

I heard Kaitlyn say, "Stay here and, in a little bit, we'll go to our bedroom." I stopped kissing Joanna; she got up and walked toward Paul. I got up too, making room for Kaitlyn to sit down. As soon as she was seated, I kissed her neck. She let out a small gasp and grabbed my hands, pulling them to the bottom of her rib cage. As I did the kissing and nibbling, I moved my hands slowly in circles. To my surprise, Kaitlyn reacted more strongly tonight than she had last night, getting much more into the kisses and nibbles.

While I was kissing along Kaitlyn's shoulder, I looked across the room. Joanna was seated on Paul's lap, and Paul was running his hands up her arms to her exposed shoulders. Joanna gave me a smile. Paul looked bored. I kept kissing along Kaitlyn's shoulder. This time, I kept kissing once I crossed her bra strap and kissed all the way to the end of her shoulder. When I was done, I stood up.

Joanna was the one who got up immediately this time. She took a few sensual steps toward me with a big smile on her face before reaching behind her and undoing her bra. She kept her eyes on my face as she peeled the bra off her and tossed it aside. When she reached us, Kaitlyn got out of the chair and left my vision as I stared at Joanna in amazement. Joanna rotated the chair ninety degrees and ordered, "Sit down." I sat down in the chair. Joanna immediately straddled my lap. She grabbed my head in both hands and said loudly, "Suck it!" as she guided my mouth to her tit. Her nipple was already hard before it entered my mouth. I sucked gently as I grabbed Joanna's ass firmly in my hands. This was so fucking insane. Last night had been crazy, but this was even crazier.

I happily sucked on Joanna's tit while squeezing her ass until she pushed back on my head. She guided to me her other tit, and I greedily sucked on it too. Last night had been hot, but tonight was far hotter. I wondered -- had tit-sucking been a part of the plan? Something they had decided on while they were in the bedroom changing into bras and panties? Joanna had walked toward me topless with total assurance.

Joanna pushed back on my head and again I let go of her tit. She guided my mouth back to her first tit, and at the same time, shifted toward Paul and Kaitlyn so I could see them easily. Kaitlyn's bra was off, and Paul was furiously sucking on the right tit, which was closest to us. I was shocked to see Kaitlyn was red-faced with anger. What was she so angry about? Were the guys frolicking on second base in front of the other couple too much for her? Was Paul doing something that made her angry?

Joanna said loud enough for Paul and Kaitlyn to hear, "Paul said it was boring to watch you kiss on Kaitlyn. He asked me to do something he'd find exciting. Do you find this exciting, Paul?" Paul nodded his head vigorously while continuing to suck on Kaitlyn's tit. Joanna laughed. She ran her hands through my hair and said quietly to me, "I hope you find this exciting. I find it very exciting."

Joanna twisted my head gently, so I was looking at Paul and Kaitlyn again. Anger was gone from Kaitlyn's face and it was replaced by something I couldn't place, but it wasn't pleasure. Paul was sucking on the left tit now, giving me an unobstructed side view of the right one. I had known my sister was well-endowed, but it still shocked me to see exactly how well-endowed she was, how proudly her tit stood out on her chest. Her areola was a light brown and looked larger than average in size. Her nipple was completely erect.

Joanna said quietly to me, "I think Kaitlyn wants you to look at her tits. I bet it's making her very excited. I'm sure she's jealous that you're sucking on my tits instead of hers." Joanna added gleefully, "I love making her jealous."

After I had suckled on Joanna for a bit, I couldn't resist looking back over at Kaitlyn and Paul. Paul was mouthing her left tit again while Kaitlyn was looking at me. We locked gazes. As we continued to stare at each other, I saw out of the corner of my eye Paul bringing up his hand to Kaitlyn's near tit. He started playing with the nipple, running his finger around it and tweaking it. It was like he was showing it off to me. The whole time, Kaitlyn moaned as lust filled her face.

Joanna said loudly, "What are you going to do tonight to your naughty girl, Brandon? Are you going to give me a hard fucking?" Hell yes! An odd look came over Kaitlyn's face. "How are you going to fuck me? Doggie-style? Doggie-style on the couch?" I didn't care where or how we fucked so long as we fucked. I had never wanted to fuck so badly in all my life. I couldn't wait to get my cock in Joanna's pussy. The odd look on Kaitlyn's face became one of longing. "How about you throw me over the arm of the couch and take me there? Would you like to do that?" Kaitlyn appeared to whimper, like she wanted me to throw her instead of Joanna over the arm of the couch and fuck her.
Kaitlyn pulled Paul off her tit. She jumped off the chair, so she was facing Joanna and me, giving me a good look at her tits. Joanna got up and faced Paul and Kaitlyn. Kaitlyn grabbed Paul's hand as she said, "Let's go!" and pulled him toward the bedroom. Paul took a good look at Joanna's tits before running off. We watched them cross the room to the bedroom and slam the door.

Once the door was closed, Joanna pulled off her panties. She walked quickly toward the couch and lay face down over the arm. "Fuck me, Brandon."

I was right behind her. I pulled off my shorts and quickly guided my cock into her hole. As she was bent way forward over the couch arm, her ass was way high in the air. As I made my initial push, I discovered Joanna was already very wet. I pulled back and then pushed my cock all the way in.

"Oh yes!" hissed Joanna. After I pulled back again, I slammed into her. "That's it! Fuck your naughty girl." I did, my body slapping loudly against hers each time I thrust into her.

"Oh, yes. I've been so naughty," Joanna mumbled into the couch.

"Does my naughty girl want a good, hard fucking?"

"Oh, yeah! Fuck me, Brandon. I want it bad."

I gave Joanna her wish, fucking her as hard as I could. The first time I had called her naughty, it had been just another way of teasing her, but I had known then that she liked being called naughty. Tonight, she had taken naughty to a whole new level, and I could tell she had found it very exciting. It had excited all four of us. I wasn't certain what I thought about Joanna enjoying being naughty, but I was too focused on fucking her silly to give it much thought.

It wasn't long before I could feel myself cumming. "Here it comes, my naughty girl."

"Give it to me. Give it to your naughty girl."

I pulled back once more before slamming into Joanna, firing a massive load deep into her pussy. I shuddered with pleasure as all of the sexual tension that had built during our joint make-out session was finally released.

It took me a bit to catch my breath. I was sweaty all over. I savored our fuck for a while before saying, "That was awesome, Joanna."

Joanna looked back at me and gave me a big smile. "I loved it too."

Joanna reached over to a towel on the coffee table and did her best to throw it to me. I pulled out and used the towel to absorb our juices. Joanna moved off the couch while holding the towel and pointed for me to sit down on the couch. I had a good idea of what she wanted, so I sat down on the edge. Joanna lay down with her head in my lap. She let the towel drop, exposing her pussy. "Now make me cum."

As I reached my hand toward her pussy, the thumps of Paul and Kaitlyn fucking started, with Kaitlyn moaning in time.

Joanna said, "Make me cum with your sister."

I slid my finger between her pussy lips and rubbed against her clit. Joanna hissed. I rubbed some more, and she was panting. She soon matched her pants with Kaitlyn's moans. I again had the feeling that I was making Kaitlyn moan as I fingered Joanna.

Joanna came before they finished fucking. After she caught her breath, she said, "Let's fuck in our bedroom."

We fucked with Joanna on top. The whole time we fucked, she'd occasionally mutter, "Fuck your naughty girl."

* * *

The next morning, Tuesday, I was awakened by Joanna amorously snuggling on me. Based upon the amount of light in the room, I'd guess we had fifteen to thirty minutes before Mom would knock on our door. Joanna and I couldn't have sex, but we could quietly make out. I tilted her head up with my hand and kissed her. The kiss morphed into a long, smoldering one.

Joanna said, "I had a great time last night. Did you?"

"Yes. It was crazy, but it was also crazy hot. You were incredible, my naughty girl."

Joanna smiled. "So you're not angry at me for being naughty?"

"No."

Joanna moved in for another kiss, which turned into another long, smoldering one. Joanna stroked my morning wood, making it even harder.

I said, "This is making me want to pee."

Joanna snorted. "Then go pee." She added sultrily, "I'll be lying naked on your bed when you get back." Joanna wore only panties when she slept with me, which meant she'd strip them off while I was gone.

I pulled on some shorts, went to the bathroom and came back. During my walk, I decided to discuss something with Joanna that was bothering me.

When I got back in the bedroom, the covers on the bed were thrown back and Joanna was lying naked on her back on a t-shirt. She wiggled her finger at me in a come here gesture. As I slid into bed next to her, I said, "Let's talk for a bit."

Joanna stretched sensuously like a cat and said, "Okay". She grabbed my hand and pulled it toward her pussy. "Talk."

"Do you think we crossed a line last night we shouldn't have? It was one thing for us to kiss and grope in front of each other but having the guys suck on tits is quite another." Particularly as I had watched my own sister getting her tits sucked.

Joanna maneuvered my index finger between her pussy lips and pushed up against it as she said, "It was a lot of fun, no one got angry or jealous, and all of us were hot and horny when we were done. I want to do it more. I think Paul and Kaitlyn want to do it more."

"Paul got to see your tits." I wasn't exactly jealous, but I would have preferred to keep Joanna's charms to myself.

"That was the point. He wanted me to make things more exciting, and I did by letting him watch us. Was it exciting for you to see Kaitlyn's tits?"

I struggled for an answer before getting distracted by Joanna moving her hips up and down, causing my finger to slide between her pussy lips. "Joanna," I said disapprovingly. She knew the rule about no-sex while my parents were around.

Joanna gave me a sexy smile. "I'll be quiet. I'm always quiet." She chuckled. "Unlike your sister."

I gave in. I lightly pressed down with my finger, stimulating the area around Joanna's clit.

Joanna said sultrily, "Was it exciting for you to see Kaitlyn's tits?"

Again, I said disapprovingly, "Joanna."

"Brandon, I won't judge you for your answer. Tonight, I want to do something like we did last night, and I want feedback as to what worked for you. Was it exciting for you to see Kaitlyn's tits?"

"Yes." I had loved seeing Kaitlyn's tits. They were the most beautiful ones I had ever seen -- just the right shape and size; wonderful skin; her areola were the right shape and color; the way they sat proudly on her chest. I was uncomfortable with how much I had enjoyed seeing them.

Joanna asked, "Did you mind my sharing you with Kaitlyn?"

"No." I had enjoyed it.

Joanna was pushing hard against my finger now and her breath was getting ragged. She said, "Good. I think my sharing makes her even more jealous." She went back to breathing deeply. I worked her clit as she liked, pushing her closer and closer. The only sound was Joanna's breaths -- she didn't moan or say anything. I surveyed Joanna as I pushed her closer to the edge; she was a beautiful, fun, sexy, naughty girl who knew how to make sex incredibly hot, and I was lucky to have her as my girlfriend. I moved my finger faster and faster, pushing her higher and higher. After a few minutes, Joanna clamped down on my hand with her thighs as she quietly came. Seeing her cum filled me with happiness.

Joanna pulled me to her. As she kissed me, she wrapped her hand around my dick. We kissed quietly yet passionately as she stroked me. She broke off the kisses and shifted to take my cock into her mouth when there was a knock on the door. Joanna gave my cock a quick kiss on its head and said, "I'll make it up to you later."

* * * *

Over breakfast, Kaitlyn suggested we go jet skiing this morning, and everyone else agreed. The cabin had two of the small one-person jet skis that you stood up on and two of the larger, two-person jet skis that you sat down on. After breakfast, Mom and Dad led the way down to the boat house where the jet skis were stored. Kaitlyn and I were right behind them, and the four of us were talking about what parts of the lake to avoid. When we got to the boat house, I turned and saw that Joanna and Paul were well behind us. They were engrossed in conversation as they slowly walked toward us. I had a bad feeling about them talking that way.

Kaitlyn said to me, "What do you want to start on?" I had turned to face Kaitlyn. "A small one or a big one? I think we should rotate the different jet skis among us, so everybody gets a turn driving each type."

I didn't answer as I was distracted by Kaitlyn's bikini top -- it was kind of a cross between the traditional bikini top and a crop top shirt. There was something about how Kaitlyn's tits pushed out their covering that emphasized their size. At the top center of her top was a peek-a-boo hole which gave me an enticing view of the top of Kaitlyn's tits.

Kaitlyn said, "What do you think of my top? It's new. I love how it feels and how it holds the girls in place." Kaitlyn shook her tits at me. It took every bit of restraint to keep my jaw from hitting the ground. "See? They barely moved."

I stood stunned for I don't know how long. I snapped out of it when Dad drove one of the big jet skis around to where we were and yelled, "Come on, kids. Let's go!"

* * * *

We spent the morning jet skiing, and all had a blast. We kept somewhat together, the two couples on the big jet skis regularly racing against each other, and the two people on the small jet skis doing likewise.

At one point, Joanna was driving a big jet ski while I held on to her. I asked her, "What were you and Paul talking about on the way to the boat house?"

"He thanked me for making last night exciting for him. And he asked me to arrange with Kaitlyn to do something similar tonight."

She seemed defensive, which annoyed me. Finally, I shook it off; I was making a mountain out of a molehill.

* * * *

After lunch, Kaitlyn, Joanna and I went to the chaise lounges while Paul headed to the hammock. The girls were wearing tiny bikinis, the same ones they had been wearing yesterday. Seeing them wearing so little was affecting me more today. After I had put sunscreen on Joanna's back, Kaitlyn said, "Would you please put sunscreen on mine? Paul's busy."

"I'll spray it on you."

"No one brought the spray," said Kaitlyn. "All we've got is lotion."

I had never applied sunscreen lotion to Kaitlyn before. I looked up at the hammock, and Paul was completely focused on his tablet. I glanced at Joanna, and she was already lying down with her eyes closed. Why not?

I squirted some of the sunscreen on to my hands and applied it to Kaitlyn's back. She pressed lightly back into my hands as I did so. Her skin felt so good and looked flawless. I was glad no one was looking at me because I had a massive hard-on. I applied the sunscreen as quickly as I could and when I was done, Kaitlyn said thanks. I arranged myself the best I could and lay down next to them.

The three of us chatted for a little bit about how much fun the morning had been, and then Kaitlyn dropped a bombshell -- "I'm thinking of breaking up with Paul when the week's over."

"You are?" I said. I discreetly looked up at Paul. There was no sign he had heard his name.

"Yeah. He's a great guy and I've loved dating him, but he drives me crazy at times. Last night was kind of the last straw."

My emotions churned in confusion. I couldn't tell if I was disappointed, sad, or happy that Kaitlyn was so close to breaking up. She hadn't announced she was definitely breaking up with Paul, so I interpreted her comment as a request for us to try to talk her out of it.

Joanna said, "Are you talking about him going for your tits while you were kissing?"

"No, though I was annoyed that I had to tell him twice to stop. This is probably TMI, but Paul is unimaginative about sex. When we're alone, he wants me to go down on him, then he does oral on me, followed by us fucking. He's good at oral -- he always makes me cum -- and he's a good fuck, but I'm tired of it being always the same. Last night, I wanted to skip the blowjob and go straight to him eating me out. I was ready to cum right away and fuck. But no -- I had to blow him first."

This was TMI, and I was a little shocked that Kaitlyn would graphically describe her sex life with Paul. But it was obviously bothering her.

Kaitlyn continued, "Paul is so different than any other guy I've dated. I've never had a guy shower me with gifts. And I loved it at first. I loved all the sexy clothes he bought me; I loved going to the expensive restaurants. But now monotony has set in. It's the same kind of gifts and the same kind of sex. My god, my closet is full of sexy dresses and expensive lingerie! I actually prefer it now when he sends a card." Kaitlyn was in the middle and turned toward Joanna. "I think that's why I put on the fashion shows at work; to get me excited about the latest lingerie Paul had sent me. I'm sorry it offended you."

"Forget it. I've already forgiven you."

"You're the best, Joanna," said Kaitlyn. "But back to Paul -- he's also too eager to have sex when we're alone. I kiss him and he starts pawing at my tits, just like he did last night. It was nice that I got him to slow down for a while. Last night's foreplay really had me fired up and I was so ready to fuck when we went to our bedroom." She paused for a moment. Picturing my sister being fired up to fuck made my head spin. "By the way, Paul wants the couch tonight." Joanna lightly laughed. "He somehow seems to have gotten the idea of fucking me over the arm of the couch." Joanna laughed some more.

The three of us were quiet for a little bit. I tried to process how I felt about Kaitlyn breaking up with Paul, but I kept coming back to Kaitlyn being fired up from last night's foreplay. A big part of the foreplay was me kissing and nibbling on her neck, and us locking eyes during the tit sucking. Was that what had gotten her so fired up? Was she trying to tell Joanna or me that her I-don't-know-what-to-call-it with me had gotten her so hot? The possibilities made my head swim.

Joanna finally said, "What if Paul learned to slow down? Would that make a difference?"

Kaitlyn shrugged. "Possibly. If he learned to slow down, I might be willing to keep going. And if he learned to be more creative. As I said, he's a considerate, caring guy. Why? Do you have an idea?"

"Somewhat. But first -- no bra and panties tonight. I'm tired of wearing a bra that is too big for me and makes my tits look tiny." Joanna turned to me. "Brandon, go jet ski. Kaitlyn and I need to have a serious girl talk."

* * * *

After lunch, we went skiing. When we got on the ski boat, Kaitlyn surprised me by sitting down next to me, forcing Joanna to sit next to Paul. It was far easier with all the noise to talk to the person next to you, so I talked with Kaitlyn. She was in a great mood, smiling a lot and laughing easily. Her "girl talk" with Joanna must have gone well. I kept an eye on Joanna and Paul while they talked. Paul was nodding his head a lot and occasionally would have a huge grin. I guessed their conversation was a part of whatever plan Joanna and Kaitlyn had come up with.

At one point, I asked Kaitlyn, "So what do you and Joanna have planned for tonight?"

She gave me a nervous smile. "Joanna wants it to be a surprise. It'll be fun. Go along with it, please?"

"What if I don't?"

"It depends on Paul. He's looking forward to having another night like last night. He told me so on the way to the ski boat. I don't know how he'll handle the disappointment of just being with me. Nothing could happen. Literally nothing could happen in our bedroom." The way Kaitlyn said it, I pictured them spending the night on opposite sides of the room, staring icily at each other. "Or we could have a big fight and break up."

"Are you that close to breaking up?"

"We were the first night here. Since we started having our little parties, we've pulled back from that brink."

I was torn. Last night, we had moved beyond what I was comfortable with, and I felt like tonight we'd keep moving past that line. I could say no, take Joanna into our bedroom, and everything might turn out fine. Or Kaitlyn and Paul could have a big fight, and we'd have a very ugly situation on all our hands. I decided it wasn't worth the risk. "Okay. I'll go along."

* * * *

When we got back to the lake house, Dad and I started working on dinner while Paul lolled on the couch with his tablet. As Dad and I made dinner, I noticed that, while Mom was showering, the girls went to Kaitlyn's bedroom and closed the door.

When Mom and Dad left, the girls disappeared into Kaitlyn's bedroom as I expected. Paul and I moved our chairs into their usual spots. Paul rubbed his hands in anticipation, so he must have had some idea of what was coming.

The door opened, and Paul and I turned to look at the girls. They were wearing terry cloth short-shorts and t-shirts they had cut off so we could see the bottom inch of their tits. As they walked, I was mesmerized by the sight of Kaitlyn's tits as they wobbled. Her t-shirt was thin so I could easily make out her nipple pressing against the material.

Kaitlyn was in the lead, and she stopped in the usual spot. When Joanna caught up to her, I was stunned to see Kaitlyn turn toward me. My eyes were wide in disbelief as she crossed the distance to me. She straddled my lap on the chair just like Joanna had always done. She said softly, "Joanna is going to teach Paul to keep his hands off her tits," and then her lips were descending toward mine. They seemed to move in slow motion for the last few inches. Did I want to kiss my sister? Should I stop her? I was frozen in place as her lips brushed mine. Electricity shot through me like I had been zapped by ten thousand volts. My heart was pounding in my chest. Kaitlyn had kissed me! The next kiss was a solid plant on my lips. Her lips felt so soft on mine. The kiss, combined with her sexy outfit, was intoxicating. I offered no resistance as Kaitlyn kissed me again and again.

I started kissing back. Passion rose within me as the surprise wore off, and I got into kissing Kaitlyn. She was beautiful, fun, sexy and smart. I had never thought about kissing her, but now I realized how much I had wanted to. Our kisses got steadily longer and more playful, with our lips grabbing and pulling. My hands moved up and down her smooth back, caressing her firm muscles. I stuck out my tongue and licked her lip. Kaitlyn pulled back and shook her head no before coming forward for another kiss. I took it that the rule for this part was no tongue in our kisses.

I don't know how long we kissed, but it seemed like an eternity. Each kiss was an experience I savored. As soon as a kiss ended, I replayed it over in my mind in the fraction of the second before the next kiss started.

I heard Joanna say, "You've been a good boy," and Kaitlyn stopped kissing me. I felt dazed, like the experience of kissing my sister was more than I could process. Kaitlyn smiled at me, turned and walked over to Paul, passing Joanna on the way.

As soon as Joanna was in my lap, she kissed me hard and pushed her tongue into my mouth. I quickly responded. Kissing Joanna wasn't new and exciting-because-it's-taboo like kissing Kaitlyn was, but Joanna made it hot by kissing me with such passion. My heart continued to pound. Joanna grabbed my hands which were on her back like they had been with Kaitlyn and she pushed them down. I dropped them down to her ass and squeezed; Joanna was wearing no panties. Joanna responded by rubbing her tits against my chest. We kissed in lots of different ways, sometimes with tongue and sometimes not but always frantically, like our kisses couldn't fully express our excitement for each other.
Eventually, I heard Kaitlyn say, "Switch back." Joanna hopped off my lap while continuing our last French kiss as she slowly pulled away. During our last kiss, I heard Kaitlyn say, "You were a very good boy." When Joanna broke off our last kiss, she headed toward Paul, and Kaitlyn was almost back to me. She said, "Neck nibbles."

I got up, and Kaitlyn sat down. I kissed her neck lightly, and she moaned. Again, she really got into my kisses and nibbles, moving to give me better access and then melting and moaning as I used my mouth on her skin. I felt like our kissing earlier had her more fired up for this than she had been last night. As I kissed and nibbled, I struggled with how much Kaitlyn and I were enjoying this; I knew we shouldn't be enjoying this as much as we were, but everyone else was fine with it so I didn't see any reason to hold back. But the internal struggle left me feeling dazed.

I kissed and nibbled my way down Kaitlyn's neck and toward her shoulder. I had to pull the shirt collar to the side to access her shoulder. I was so damn horny and couldn't wait to fuck Joanna silly. When I had kissed all of Kaitlyn's shoulder that I could reach, I looked over at Paul and Joanna. Joanna was lolled against Paul with her head resting on his shoulder. Paul's hands were lightly stroking her stomach. I realized then that with the crop top, Paul could have easily felt Joanna's tits while I was busy with Kaitlyn.

Joanna jumped up and held out her hand. "Come on, Brandon. They've got the couch tonight."

Sex with Joanna was incredibly hot as both of us were so fired up. It was like a wrestling match except we were co-joined in the middle. When we were done, I was physically and emotionally spent.

* * * * Chapter 3 * * * *

Wednesday, Joanna woke me by snuggling on me. When she saw I was awake, she gave me a kiss. "Had fun last night?"

"Mostly," I said with little enthusiasm. First thing in the morning was when I felt the worst about our evening activities. Joanna obviously didn't share my regrets or concerns. But then again, she wasn't making out with a sibling.

Joanna smiled. "I had fun kissing Paul. I hope that doesn't bother you. It wasn't anything serious to me, just some naughty fun. And it was what Kaitlyn asked me to do to try to improve things with Paul."

"How is you kissing Paul going to improve things between her and him?" The four us of switching for kisses wasn't sitting well in my stomach.

"Kaitlyn can't get him to listen to her about slowing down, but he listened to me. So now hopefully he'll go more slowly with Kaitlyn."

I didn't want it to make sense, but it did.

Joanna waited, as if she was expecting me to make a similar remark about kissing Kaitlyn. When I didn't make one, she said, "Look, I'm not going to judge you or Kaitlyn for what you did last night. I wouldn't have felt good about kissing Paul if you hadn't been kissing Kaitlyn. I would have felt like I was cheating on you. If it's not even, it's not fair." Joanna's face lightened. "An important part of my friendship with Kaitlyn is that we don't judge each other. She's okay with whatever I do; and I'm okay with whatever she does, including kissing you. And you did get her worked up with your kisses, which was the goal of last night." Joanna chuckled. "I could tell she didn't want to stop kissing you. But she had to because you're mine, all mine." Joanna chuckled some more.

Kaitlyn had been so eager to kiss me. And it had been so damn good kissing her...

I asked, "You're not going to tell anyone I kissed Kaitlyn, are you?"

Joanna snorted. "Of course not. I'd do nothing to hurt Kaitlyn. And when I talked about the plan with Paul on the boat yesterday, I made him promise to never tell anyone. Did you enjoy it?"

"What?"

"Kissing Kaitlyn, you idiot!" Joanna said with a smirk.

I didn't want to tell her yes, but I didn't want to lie. I went with downplaying the truth. "It was enjoyable. I would have never done it on my own, but I didn't mind it when she kissed me."

"The whole evening was enjoyable. I'm looking forward to doing it again tonight."

* * * *

We did jet skis after breakfast. At one point, Kaitlyn suggested she ride with me and Joanna ride with Paul. Once we were away from the others, Kaitlyn said, "Thanks for going along with everything last night. I think it was a good lesson for Paul. He was more flexible about having sex last night than he usually is. I hope you aren't upset about Joanna kissing Paul."

"I'm not. I'm not comfortable with it, but I understand why we did it. Joanna enjoyed it. She views it as innocent fun."

"Good." Kaitlyn gave me a squeeze. "Stop for a minute. I want to get wet."

I brought the jet ski to a stop. Kaitlyn jumped into the water and swam around for a minute. She then came over to the jet ski, put her hand on it, and looked up at me. I asked her, "What does Paul think of what you and I did last night?"

"He didn't say. He probably thinks it was disgusting and weird." Understandably so. "Was he bothered by it? I don't know. He's a very simple guy; as long as he can play his game and have sex, he's happy. I can tell he's enjoyed the fashion shows, and that he liked kissing Joanna. And we had awesome sex last night, which made him very happy. Did you and Joanna have awesome sex?"

I blushed a little. "We did."

"Great! Paul was probably too focused last night on having a good time with Joanna to have a reaction to you and me. And I don't think he'll say anything negative for fear that all of his fun at night will come to an end."

All of that made sense. Kaitlyn then did something I've seen girls do countless times - pull her top out for whatever reason. This time when she did it, she gave me a brief view of her tits. She was looking at her top when she did it, so she may not have realized I could see her tits. Or maybe she didn't think my seeing her tits briefly was a big deal after I had gotten a good look at them the other night. Part of me felt that I shouldn't look, but I couldn't resist looking as she had sensational tits. Her show was another one of the things that shouldn't happen that whose happening made my head spin.

I asked, "Are you thinking better about Paul after last night?"

"Too early to say. Paul is the first boyfriend that I've accepted as he is. Despite his flaws, he's a good boyfriend. But he's not a great boyfriend. If I knew of a guy who I thought would make a great boyfriend, I'd dump Paul in a heartbeat. What I don't want to do is dump Paul and then date a guy that I can manipulate without really trying."

"You're that manipulative?"

"I don't know if I'm so manipulative or if I'm so good at it." Kaitlyn's face turned very serious. "I've learned the hard way that you can't trick someone into being a better person, or into making the right life decision. I can't change people; they'll only change when they want to change. I've felt much better about myself since I started dating Paul because I haven't tried to change him. And I was open and honest with you and Joanna about why I wanted you two to date."

"Manipulating us into dating would have been bad."

"You say that, and I see how much happier Joanna is now that she's dating you. I took a big risk in asking you to date her."

Was she saying that manipulating was a good thing? "We would have figured out eventually that you had manipulated us, we would have been pissed at you and it would have hurt our relationship."

"And your relationship is great without me doing any manipulation?" That smarted. I opened my mouth to rebut her comment, but I couldn't think of one. Kaitlyn then said, "I used to think in too many cases that the ends justified the means. Or maybe I used to enjoy manipulating people more than I do now. I don't like it when I do it now."

"So don't."

Kaitlyn laughed. "Good suggestion. I try. Then things don't happen the way I want them to happen. Look at you and Joanna. Joanna won't accept that you're dating her because you want to. She thinks you're only doing it because of me. That drives me crazy as I think you're a great couple. It's the type of situation where I'm tempted to accept the ends justifying the means." Again, I had the feeling that she was a lot deeper than most other girls. She shook her head. "I wish now I could have had her come over when you were home, had you two hit it off, and then you decided to go out on your own."

"But that wouldn't have happened. I wouldn't have dated Joanna if you hadn't asked me to."

"Yeah. It's just that...I've come to realize that Joanna needs to make her own choices. Even if I'm totally certain about what she should do next, I need to let her come up with the idea on her own. Hopefully, at some point, she'll choose to let herself fall in love with you."

Another painful topic. "I hope so, too." But I had no idea when that would happen.

"Thanks for not judging me. I think there aren't many guys a girl could tell that she's very manipulative, and they'd not judge her for it. I haven't told Paul about my habit of manipulating."

I shrugged. "If I got angry at you, how could I date your friends?" Kaitlyn giggled. "Seriously, I've been hanging out with two non-judgmental women this summer, so I'm learning to be non-judgmental."

Kaitlyn climbed out of the water. When she got back up, I asked, "Don't you think it's weird for me to be getting you excited every night?"

Kaitlyn shook her head sadly, "I think it says more about how bad things have gotten between Paul and me that I find innocent kisses from you much more exciting than what foreplay he does." Kaitlyn grinned. "We're all having fun. For whatever reason, it's like we've all gotten blank checks, during that one hour, to have fun like we'll never have anywhere else. I'm never going to kiss you at home. Joanna is never going to kiss Paul after this week. I like the freedom we've been having, and I'm looking forward to more freedom tonight."

* * * *

When Kaitlyn and I finally got back to the rest of the group, Mom and Dad gave us disapproving looks for being gone so long. We were supposed to swap jet skis every twenty minutes or so, and Kaitlyn and I had delayed this swap. Paul and I hopped on the small jet skis and raced each other. We played for a while longer before heading back for lunch. The rest of the day was pleasant and completely normal. The only slightly unusual thing was that after dinner Paul volunteered to do all the laundry, and Kaitlyn asked Joanna to help him to make sure "he washes the girly stuff correctly".

I found the normality of it all disturbing. I had kissed my sister last night. I was going to kiss her again tonight. I felt like people should be acting differently because of it, but no one was.

As soon as Mom and Dad left, the girls went into Kaitlyn's bedroom. Paul and I got the chairs into position and sat down. I asked, "Did you have fun today?"

"I did". Paul winked at me. "And I'm hoping for even more fun tonight."

The door to the bedroom opened, and the girls came out again in crop tops and terry cloth shorts. Everything was basically a repeat of the night before - Kaitlyn came to me for kisses, Joanna came for French kisses, and Kaitlyn came back for neck nibbles. When I reached my usual stopping point, I looked up and saw Joanna lolling against Paul again. There was something about their familiarity that bothered me.

Paul called out, "Keep going!" and laughed. What an ass! I couldn't believe he wanted me to continue to make out with his girlfriend.

Then I had an idea - I'd get back at Paul by driving his girlfriend crazy. Suddenly, I wanted Kaitlyn to dump him in the worst way. I'd get Kaitlyn super-excited so the next time she was with the big doofus, she'd be so frustrated with his pathetic foreplay that she'd kick him to the curb.

I moved back up to Kaitlyn's neck and started kissing upwards from about halfway up. When I got close to her ear, I gently nibbled on her earlobe.

"Oh my God!" gasped Kaitlyn.

I inwardly smiled. I nibbled a few more times on her earlobe while I listened to her breathing quicken.

Kaitlyn gushed, "You're giving me goose bumps!" She sounded shocked at how much I was exciting her.

I blew softly in her ear and got another gasp. I went back for another nibble when I heard Paul say to me, "Check out her nipple!"

I looked down, and it was easy to see through Kaitlyn's thin crop top that her right nipple was completely erect. There was something about clearly seeing the outline of her nipple and that it was so stimulated because of me that greatly excited me. It looked so perfect, so inviting...

Paul said to me, "Go ahead and feel it."

I looked over and Paul had his hands on Joanna's tits under her crop top. Part of me was instantly jealous, but then it was like my hands moved on their own accord to slip under Kaitlyn's crop top. I gently cupped her tits and...

...I completely forget about everything in the world except Kaitlyn's tits. They felt perfect in my hands - just the right shape, the right size, and the right amount of heft. I savored their perfect-skin smoothness as my hands moved over them. I heard Kaitlyn suck in her breath. Initially, her left nipple wasn't fully erect like the right, but I quickly got it erect by tweaking it with my fingers. I felt like a kid in a candy store - that wasn't quite right, but it was close; I had the feeling that I had free reign to hold and squeeze something that I had deeply wanted to touch but had thought I never would. I had admired my sister's tits for years, and now I had my hands on them with her approval, and apparently the approval of her boyfriend and my girlfriend.

Kaitlyn turned and looked up at me, an inviting look on her face. I felt like I was falling as my lips moved slowly toward her. Down, down, down I slowly went until my lips touched hers.

My lips had barely touched hers before Kaitlyn pushed her tongue into my mouth. I opened my mouth wide and let her tongue in as I continued to squeeze her tits. This was so hot, so crazy; to be Frenching my sister like this. And she wanted it; she totally wanted me doing this - her tongue was dueling mine fiercely; she was pressing her tits into my hands; she was moaning every time I squeezed or tweaked. I was totally inflamed with lust, and I needed to fuck. I needed to fuck right now.

I broke off the kiss and looked over at Joanna and Paul. They were Frenching and groping like Kaitlyn and I were. Joanna must have noticed me looking at them as she broke off their kiss and stood up. She grabbed her crop top, pulled it over her head and threw it aside. She grinned mightily as she walked toward me while swaying her hips sexily. When she reached me, she took my hand and pulled me toward the couch. When we got to the couch, she pushed me to lie down the length of the couch on my back. She grabbed her shorts and slowly pulled them down while wiggling her ass. It was a crazy sex show. I stared at her neatly trimmed, dark brown bush while she slowly pushed her shorts to the floor.

Joanna stepped out of the shorts and climbed on to couch on her knees. She straddled my face and commanded, "Eat me." I stuck my tongue upward and parted her pussy lips. Her pussy was full of moisture - the wettest I could remember her being. I ran my tongue up and down the full length of her pussy, exploring how wet she was. I liked Joanna's taste and slurped up her juices as quickly as I could. I brought my hands up to cup Joanna's ass to help her balance. I'd done oral sex on Joanna many times, but this was the first time she had ever sat on my face like this.

As I slurped, I suddenly heard Kaitlyn's voice say, "Fuck, yeah!" Based on the loudness, she was close by - definitely not in her bedroom. With Joanna's legs pressed lightly against my ears, it was hard to place where the sound had come from. I gave Joanna a couple more licks before I heard Kaitlyn say, "That's it! God, yes. Lick me, Paul! I'm so damn wet!"

I pictured this part of the living room - the coffee table to my right was the center of the furniture here. Above my head was the TV and on the opposite side of the TV were two comfy chairs that had low, U-shaped backs and thick cushions to sit on. It was from there that I decided I was hearing Kaitlyn. Knowing that my sister was having oral sex and was probably naked so close to me drove me wild. I redoubled my efforts to make Joanna cum.

I made a series of quick licks around Joanna's clit as Kaitlyn continued to moan. I had no idea how I was doing as this was a new position, and I couldn't hear Joanna's breathing over Kaitlyn's loud moans. I took a break from focusing on eating Joanna out to look upwards. She was holding her upper body straight, and her body seemed so long from this angle. She had her right arm on the couch back to help her keep her balance. Her small tits really stood out from her chest. I took a mental picture and stored it away as one of life's precious memories before I returned my focus to making her cum.

As my tongue danced around Joanna's clit, I listened to Kaitlyn continue to moan. The two couples having sex like this was incredibly crazy; like something out of a porn movie. What would Joanna do once I made her cum? Would she fuck me in front of Paul and Kaitlyn?

Kaitlyn's moans got even louder. "Oh! Oh! Oh!" It was incredibly erotic to hear my sister's cries of ecstasy. She sounded close to cumming. I had no idea how close Joanna was, so I continued frantically working her clit.

I heard Kaitlyn yell, "Yes!" and then she was quiet. A few moments later, I heard movement from that part of the room. Were they going to fuck in the chair right next to us? Then I heard them moving away from us and the door to the bedroom close. Shortly after that, Joanna came, flooding my face with her juices.

After Joanna clambered off me, I sat up. Joanna grabbed her clothes off the floor and said, "Let's go to our bedroom." I noticed Kaitlyn and Paul's clothes were still strewn all over the floor. Joanna smiled and said, "They'll have to pick them up later."

* * * *

The next morning Thursday, I was awakened by the sound of someone entering our bedroom. I looked up to see it was Kaitlyn, dressed in her crop top and shorts from last night. Joanna was snuggled against me on the wall side, so I had an unobstructed view of Kaitlyn.

Once Kaitlyn saw I was awake, she said quietly, "Good morning!"

I shook my head. What was Kaitlyn doing in my room? She had never come into my room when I was with a girlfriend before. From the light, it was probably ten minutes before Mom would knock on our doors. As much as I loved my sister, I didn't want her to see me and my girlfriend in bed naked. It bothered me that another social rule was being broken. "What are you doing here, Kaitlyn?"

I noticed Kaitlyn had something in her hand, which she dropped on the floor. Joanna was awake now, and she partially sat up so she could see.

Kaitlyn said, "Last night, Paul got a look at Joanna's naked backside. I want to keep things even." With that, she turned around. She grabbed her crop top, pulled it off and dropped it on the floor. She grabbed her shorts and pulled them slowly down while sexily wiggling her ass like Joanna had done the night before. Joanna laughed good-naturedly. I admired Kaitlyn's beautiful ass as she put on her show. She was a curvy girl and had a full, nicely-rounded ass. Her firm ass cheeks practically begged to be squeezed. Kaitlyn has to be the sexiest woman in the world. Eventually, Kaitlyn was squatting on the ground. There was enough light that I could see her stepping into something. Then she was moving upwards, swinging her ass side-to-side again, as she slowly pulled up her bikini bottoms. When she reached her full height, she pulled the bottoms into position. In her hand was her top, which she quickly put on while continuing to face away from us. She gave us a look over her shoulder, smiled, and said, "See ya soon."
Joanna said, "Kaitlyn! I'd like to have a long talk with Brandon. Could you cover for me at breakfast?"

"Sure. Talk as long as you want." And then Kaitlyn slipped out the door.

I looked at Joanna. I was curious as to what she wanted to have a long talk about. Last night, we had crashed right away after we had fucked, so there hadn't been a chance to talk.

Joanna said, "I want to talk about last night. It went waaay further than I was expecting. While you were kissing on Kaitlyn's neck and shoulders, Paul asked me several times if he could feel my tits. I said no, that we could only do what you and Kaitlyn were doing. Paul told you to feel Kaitlyn's tits so he could feel mine. He was happy when he saw you kiss Kaitlyn as that meant he could kiss me. Everything had me so excited I had to have sex right there and then."

So Paul had been more than fine about what Kaitlyn and I had done. Probably thought it creepy but was happy to ignore what we were doing if he could do what he wanted with Joanna. I was not in a happy mood.

Joanna smiled at me. "I've said it before, and I'll say it again; it was all harmless fun. This morning, I wanted to tell you why I think that. I have three reasons, the most important of which is you're my guy; you're the one I want to have sex with, the one I want to sleep with, the one I want to wake up with, the one I want to have fun with." That made me feel warm all over. Joanna had never declared her affection for me so strongly before. "Reason number two is that I trust you and Kaitlyn. You aren't going to do anything to hurt me. Hopefully, you trust me to not do anything that hurts you."

I liked how this talk was going. "I do, Joanna." And then I asked, "Do you trust Paul?"

Joanna chuckled. "No. Well, sort of. I think he'll keep his word, but he's very aggressive about making out and will push things if he sees an opportunity to do so."

"Like last night."

"Yes. I'm glad you were there to keep him from going too far. But it doesn't really matter as he'll be out of the picture soon."

"Oh really?"

"Yeah. I watched him and Kaitlyn, and he doesn't excite her at all. I think she'd dump him this morning if there was some convenient way of sending him home. But there isn't, so she'll try to make their relationship last until we get home."

I nodded. That made sense, and I was glad that Kaitlyn would dump Paul soon.

Joanna said, "This week has been a perfect storm. I think whatever you and Kaitlyn do is harmless because I trust you, and I think whatever Paul and I do is harmless because I probably won't see him again after this week. And I think it's important that we switch partners up so Kaitlyn can be happy as she keeps their relationship on life support." Joanna smiled. "I like alternating as I have fun with Paul, and then I have even more fun with you."

I smiled at that.

Joanna tapped her finger on my chest and said in a light but commanding voice, "So don't expect anything like this to happen again. You're to never kiss another girl besides Kaitlyn, and you can only kiss her for the rest of this week. After that, you're my guy full-time. Understood?"

Exactly what I wanted to hear. I kissed Joanna and then said, "Understood."

"Good." Joanna smiled. "There's something else I wanted to discuss. The other day, when Kaitlyn was discussing how Paul bought her so much stuff, it probably sounded very mercenary to you; like she's only dating him for the money he spends on her. And now that she has so much stuff, she's lost interest in him."

I thought back to the moment. "It did sound that way."

"There are two reasons why a girl wants a guy to spend money on her. One is that she wants to raise her lifestyle. I've done that. I hate being poor relative to all of my friends. I've dated guys primarily because I wanted them to spend money on me."

"And they were jerks."

"The ones I dated were. But there are nice guys who are happy to spend money on you. There's a reason why young women marry rich guys who are old enough to be their fathers - financial security has a lot of appeal in a world where men have more wealth than women. If I dated someone like Paul, his willingness to spend money would go a long way toward keeping me happy. But I don't think that's what Kaitlyn is looking for."

This was interesting. "What is she looking for then?"

"I think she views Paul spending money on her as a sign of affection, and she's looking for an openly-affectionate guy. They have this great synergy in that he likes buying her sexy clothes, and she likes dressing up sexy for him. The Friday Paul was arriving to spend his first weekend, Kaitlyn was so excited about dressing up sexy for him that she couldn't resist sharing with the rest of us at the office. That was her first fashion show there." I wished I had seen it. "But Kaitlyn doesn't need expensive clothes to dress sexy. You saw that last night."

"I did. She looked very hot last night." I belatedly added, "And so did you."

Joanna rolled her eyes slightly. "So her not being excited about Paul now isn't due to how full her closet is." Joanna looked thoughtful. "Something has changed since the end of college. Any idea what?"

"No." I was a little surprised our conversation had taken this turn. "I spent very little time with them at school."

Joanna sighed. "Well, Kaitlyn will probably tell me everything next week." She started climbing over me. "Time to go help make breakfast." Once she was out of bed, she threw on her nightshirt and said, "I'm so happy now. I wish Kaitlyn was happy with me." And then she left.

I lay on the bed, thinking about our conversation. A weird side effect of our group make-out sessions seemed to be that Joanna was much happier with our relationship, much closer to saying 'I love you.' Was it because the sessions required me to trust her so much? Whatever it was, I felt good about last night's session even though Kaitlyn and I had gone way, way over the line. If everyone else was fine with it, why shouldn't I be?

When I came out for breakfast, Mom gave me a concerned look. Was she worried about Joanna and me having a long talk? Or did she suspect what the four of us were doing during her and Dad's walk?

During the morning's water skiing, Kaitlyn and Joanna regularly changed sides of the boat, and we guys almost always talked with whoever was sitting next to them. Kaitlyn was very happy when she talked with me. She didn't look happy when she was talking with Paul.

When the morning's water skiing was done, Kaitlyn had Joanna stay behind as the rest of us headed up to lunch. When the girls came into the lake house, they were giggling. Shortly thereafter, Kaitlyn told Mom that she and Joanna were going to go shopping after lunch and asked what was needed from the store. After Mom ate, she made a list and went over it with Kaitlyn.

I asked Kaitlyn, "Can I come with you?"

She gave me a smirk, and said, "No. It's a girls' shopping trip."

Once we were all done eating, I walked Joanna down to the minivan. She got in the passenger side, lowered the window, and said with an impish grin, "We're going to do some naughty shopping." She gave me a kiss, and then she and Kaitlyn were gone.

* * * *

The afternoon wasn't much fun without the girls as I was beginning to loathe Paul. The girls didn't get back until almost time to make dinner. Over dinner, they were all giggles. Or Kaitlyn was all giggles - Joanna swung from giggling to being nervous or anxious. But both were giggling madly when they went to Kaitlyn's bedroom after Mom and Dad had left. Paul and I waited impatiently for the girls to come out as we didn't have anything to say to each other. As every other night, Paul and I were wearing shirts, shorts and no shoes.

The door opened, and I turned to see Joanna stride out. She was wearing white high heel shoes; red panties that were cut low at her crotch and high on her waist; a shiny, plastic black belt; and the only thing above the belt was a raspberry-colored beret. She looked super-hot. And then Kaitlyn came out behind her dressed the same and turned the hotness up to eleven. She had great tits and just a sexy air about her. Watching her walk had me rock hard.

Joanna and Kaitlyn walked to in-between Paul and me as usual, and I was mildly surprised when Joanna turned toward me. I heard Kaitlyn say to Paul, "Be a good boy and you'll get your reward later." And then Joanna was on my lap.

Joanna kissed me on the lips, and our kisses quickly became very hot; short kisses with lots of passion. It was weird that kissing my girlfriend was now a hot, novel experience, but this week was weird. I had no idea of what the limits were. With the way the girls were dressed, we were clearly getting crazy tonight, beyond what we had done before. I decided to stay with the same limits as the first round last night.

After a few minutes of kisses, I stopped and leaned Joanna back from me. I said, "What a naughty outfit." Joanna wore high heels to work, but she'd never worn them on a date with me. The panties and belt were gaudy and looked cheaply made. I suspected the girls tried to spend as little as possible on their outfits and had picked clothes they felt they would look equally good in.

Joanna blushed a little. "You like it?"

"I love it. You look so hot in it, so very naughty." Joanna beamed in pleasure. "You like being my naughty girl, don't you?"

"I like being naughty."

"You look good enough to eat," I said as I moved my mouth slowly toward her tit.

"Not yet," said Joanna as she intercepted my head and brought my mouth up for another kiss.

We kissed for probably another minute before Joanna stood up. She turned and walked across to Paul, and Kaitlyn walked across to me. If Joanna looked hot, then Kaitlyn was on fire. The belt around her waist and the high-cut red panties emphasized her narrow waist and curvy hips. Her perfect tits swung gently side to side as she sashayed over to me. My opinion that my sister was the sexiest woman in the world was reconfirmed.

Once Kaitlyn was on my lap, she leaned back to give me a good look at her. "You like?"

"I like. You're an incredibly sexy woman. You could make a blind man see dressed like that."

Kaitlyn laughed before coming in for a kiss. During our next kiss, I pushed my tongue forward between her lips and she eagerly opened her mouth to accept it, moaning once my tongue was in her mouth. I had been unprepared for Frenching with my sister last night, but I was ready and eager tonight. I knew it was wrong; I knew I shouldn't, but the other three were pushing me to do it and - damn it! - I wanted to do it. I loved it - I loved holding Kaitlyn close, the feel of her skin and most of all the sensation of our tongues frolicking together while our mouths were locked. I had never enjoyed kissing someone so much before. The kissing had my cock almost painfully hard. The wickedness of passionately kissing my sister in front of my girlfriend and her boyfriend while my parents were blissfully gone on a walk was driving me crazy. It was sick, weird and immoral, but it was also incredibly erotic.

Kaitlyn shifted her weight as she kissed me so that my cock was now pressing against her pantie-covered pussy. Had she intended that? No, she couldn't have intended that as this round was to be kissing with nothing sexual.

Then Kaitlyn shifted her weight again, rocking her hips forward to press more of my cock against her pussy. And then she rocked back, relieving the pressure. She continued lightly rocking back-and-forth as we frantically kissed. When I had thought kissing my sister was as hot as it could get, she managed to turn it up hotter.

Kaitlyn stood up suddenly. I could have kissed her for hours, but I knew she and Joanna had a plan for the evening. Were they even bothering to try to teach Paul better foreplay technique? I watched Kaitlyn's ass as she swung it slightly back-and-forth on the way back to Paul. The panties covered about half of her ass cheek, providing some shaping to an ass with great shape.

When Joanna straddled my lap, she said, "Hands, no mouth." I assumed she was stating the rules for how I could touch her tits.

"May I kiss?"

"You certainly may," said Joanna as she lowered her mouth toward mine. As we kissed, I brought my hands up, cupped her tits and gave them a light squeeze. We did a series of soft kisses that ended in loud smacks as I gently explored her tits. I didn't know if Frenching was permitted during this part, so I decided to let Joanna initiate any tongue. When I squeezed her nipples between my fingers, Joanna pushed her tongue against my lips. I brought my tongue forward and met her tongue outside of my mouth. We had a sort of sword fight with our tongues (a tongue fight?). It was silly and childish, and a lot of fun. After the extreme sexual intensity of making out with Kaitlyn, it was good to have fun. I felt a swell of affection for Joanna - she really was a great girlfriend.

I stopped the tongue fight, moved my hands aside and said, "You have wonderful tits."

"Kaitlyn's are better." Joanna was obviously bothered by her best friend's anatomical superiority.

"So? She has wonderful tits, and you have wonderful tits; just different types of wonderfulness. And your tits suit my naughty girl."

Joanna stood up. "Thanks." There was more sadness in her voice than happiness. I smiled at her, trying to show her how happy I was to have her as my girlfriend. I watched her as she walked over toward Paul. She had great legs - better than Kaitlyn's - and they looked even better in the high heels. She had a very nice ass. A little before she got to Paul, Joanna looked back and saw me looking at her.

Kaitlyn was by my side. To my surprise, she didn't hop on my lap. Instead, she looked back at Joanna and smiled; then turned back to me and said, "Stand up."

I stood up and looked over to see that Paul was doing the same.

Kaitlyn grabbed the bottom of my shirt and pulled it upwards. I bent forward so she could take it off me more easily. Once the shirt was off of my head, I looked over and saw Joanna doing the same to Paul. The girls dropped to their knees while looking at each other. They nodded to each other and turned back to their man. I looked down to see Kaitlyn grab my shorts and pull them down. She grabbed my boxers and pulled them down too. As I stepped out of them, I looked over and saw that Paul was naked like I was.

Kaitlyn stood up while pressing me back onto the chair. Once I was seated, she straddled my lap and kissed me hard on the lips. As soon as her tongue was in my mouth, I squeezed her tits. The sexual intensity was back up to eleven. Kaitlyn broke off the kiss, put her hands behind my head and hissed, "Suck them!" as she pulled my mouth to her nipple. Kaitlyn moaned as soon as I started sucking. I felt like a starving baby who was desperate to nurse.

"That's it, Brandon. Suck on my tit." Kaitlyn ran her fingers through my hair as she kept up a quiet monologue. "It feels so good. I've been wanting you to suck on my tits since I watched you suck on Joanna's tits while Paul slobbered on mine." Her fingers running over my scalp were giving me thrills. "Oh, yeah. I so like that." I stopped sucking on Kaitlyn's tit and instead kissed around her nipple, giving a little suck with each kiss. "Damn that feels good, you sneaky bastard. You don't know what you do to me, Brandon. I love it. I love the feel of your mouth on my tit. Time to suck on the other one." Kaitlyn shifted me to her left tit. "You've got me so excited, Brandon. I'm probably sopping wet."

Kaitlyn shifted her position and again my cock was pressed against her pussy. She started rocking her hips back and forth, grinding her pussy against my cock as I sucked on her tit; only the thin material of her flimsy panties was keeping us from having sex.

Kaitlyn said in a quiet voice full of passion, "I want to fuck you, Brandon. I want to feel your dick inside of me. I want you to make me moan, make me scream. I want you to cum inside of me, to fill me with your cum."

I couldn't take it anymore. I pushed Kaitlyn off of me and stood up. I had to end it now or I'd be throwing Kaitlyn down on the couch and ripping her panties off. I looked over at Joanna and Paul - Paul was slobbering on her tits enthusiastically while Joanna was running her fingers through his hair. It took me a moment to catch my breath enough to say, "Joanna, let's go to our bedroom."

I held my hand out to Joanna as I started walking toward our bedroom. She hopped off of Paul and walked quickly over to join me. I couldn't look at Kaitlyn - she had pushed me past what I could take from her, and I had to get away.

Once I had closed the door, Joanna dragged me by my cock over to the bed. She sat down on it and took my cock into her mouth while I stood. She bobbed two or three times before I exploded in her mouth. I came and came and came. I didn't know I could make so much cum. Joanna kept bobbing her head, sucking it all down.

Once I was spent, Joanna moved back on the bed and started removing what little she was wearing. "Someone was excited. Did you have fun with Kaitlyn tonight?"

I saw no point in denying it. "I did. That was crazy. Too crazy. Did you have fun with Paul?"

Joanna was naked now, and she patted on the bed for me to join her. "I did. I was very naughty with Paul tonight. He wants to fuck me. Do you want to fuck Kaitlyn?"

I felt like a huge pit had opened up in front of me. That was the obvious direction our make-out sessions were going. And Kaitlyn had enthusiastically endorsed the idea of me fucking her. "I can't, Joanna. She's my sister." I closed my eyes. It was painful to think this hard about the subject. "It's wrong. And what if our parents found out? Or people at--"

Joanna put her hand on my leg and said, "Relax. I'm not asking you to fuck Kaitlyn. She and I agreed before tonight that we'd never have sex with someone who wasn't our boyfriend; no oral either way and no fucking. Tonight was probably as far as we'll ever go." Joanna's hand slipped up my leg and grasped my cock. "So I'm asking you a hypothetical question; do you want to fuck Kaitlyn?" My cock started stiffening as she stroked it up and down. "Do you wish you could fuck Kaitlyn, even though you can't because she's not your girlfriend?"

I couldn't avoid the truth. "Yes, I wish I could fuck Kaitlyn. I'll never do it, but I definitely want to do it."

Joanna released my cock and swung her body over mine. I was lying on my back and now her crotch was on top of mine.

I asked, "Are you happy with that answer?"

Joanna positioned her pussy lips on top of my cock and started sliding back and forth on my cock. She looked down at me and smiled. "I am. I'm glad you're so honest with me." Joanna partially sat up, putting her hands on my chest and leaning on me so she could slide her pussy more easily up and down my cock. I was completely hard again. She just smiled at me as she continued gliding her pussy back and forth. And then she stopped gliding and rose up on one leg. She grabbed my cock and guided it to her pussy before slowly sinking down on it.

Once I was fully embedded in her, Joanna said, "Now fuck me like you want to fuck Kaitlyn."

* * * * Chapter 4 * * * *

I drifted through Friday morning. My sister had told me in no uncertain terms she wanted to fuck me, my girlfriend had weaseled out of me that I wished I could fuck my sister, and they were all smiles and laughter this morning. Paul was all smiles too, laughing and cutting up with them.

We water skied, and I skied miserably when I was out on the water. When Mom or Dad skied, thankfully Kaitlyn steered with Joanna as lookout as I would have been a nautical hazard. I mostly stayed close to the lookout seat though facing away so Mom couldn't see my face, and I did my best to look cheerful while my brain struggled to process last night. What stuck out was how much more aggressive Kaitlyn had been. Before last night, I could write off everything Kaitlyn and I had done as innocent fun. There was nothing innocent in how she had acted last night. I tried to think of reasons for the change and came up with nothing.
But had anything changed? Joanna was still my girlfriend; she had made it clear she wasn't going to have sex with Paul and had said Kaitlyn had agreed to not have sex with me. But Kaitlyn last night had made it abundantly clear she wanted us to fuck. Kaitlyn and Joanna had spent the whole afternoon together. Had they miscommunicated?

I did feel like one thing had changed. When one of the girls was skiing and Mom and Dad were steering and doing lookout, Paul boldly flirted with the other girl, particularly Joanna. I couldn't hear what he said over the engine noise, but there was no mistaking how he looked at them and how much he enjoyed flirting with them.

Joanna checked with me occasionally, but Kaitlyn spent more time sitting next to me. She didn't say anything; she just put her hand on me in a way so that Mom and Dad couldn't see. Her touch thrilled me. Deep down, I knew I couldn't resist Kaitlyn. My desire for her had been building steadily through the week. She was the sexiest woman I knew. If an opportunity came up for us to fuck and Joanna didn't stop us, Kaitlyn and I would do what she wanted. At the same time, she was my sister, and I knew we shouldn't have sex. Especially because Joanna and Paul would know what we did. What if Paul got jealous and went to my parents? That'd make our lives a mess.

How would Joanna respond to Kaitlyn and me fucking? Would it be the end of our relationship? She had seemed almost happy when I said I wished I could fuck Kaitlyn. Why would my girlfriend want me to fuck her best friend, my sister? Was it that she got off on the idea of a brother having such immoral desires for his sister? Or was there something else? I had the feeling Joanna and Kaitlyn were working together to get Kaitlyn and me in bed, and it was only a matter of time before it happened.

For lunch, I made a sandwich, wandered out onto the deck and made for a far corner. I wanted to be alone so I could pull my thoughts together enough that when Mom and Dad "napped", I could have an intelligent conversation with Kaitlyn and Joanna about what was going on.

To my surprise, Mom came out of the lake house and sat down next to me with her lunch. We chitchatted for a while, and I did my best to act normal.

Finally, Mom said, "What's wrong, Brandon?"

"Wrong, Mom?"

"You've been acting out of sorts this morning. What's wrong?"

Your daughter wants to fuck me, I'm probably going to let her, and I think my girlfriend is okay with the idea. But other than that, everything's normal.

"I don't know, Mom. I think I'm worn down. I do a lot of physical work at the golf course, and I've been out on the water constantly since we've been here. Maybe I should take a big nap this afternoon while the rest of you water ski."

"Don't lie to me, honey. I know something's going on."

Oh shit! Does she suspect what we've been doing at night? I had to say something was wrong, but what?

I sighed and shook my head to give me time to come up with something, and then said, "I don't get along well with Paul."

"You haven't been upset for two days because of Paul."

True. As I didn't know exactly what Mom had observed/figured out, I decided the best course of action was to keep my mouth shut. I shrugged and picked up my sandwich.

Mom said, "You're upset about Joanna, aren't you?"

My eyes widened. Did Mom suspect what Joanna and Paul had been doing? If she did, she probably suspected what Kaitlyn and I were doing. I decided to hedge the best I could. "Yeah. Things have been different between us the last few days."

"Oh, Honey," Mom said in an 'it-hurts-me-more-than-it-hurts-you' tone. "I had worried Kaitlyn and Paul might break up during this week, but you and Joanna breaking up hadn't crossed my mind."

"I don't think we're breaking up." We'd happily fucked last night.

"You two are pulling away from each other. Look Honey, being together constantly for a week is very stressful, particularly when you're with the same people and are doing the same things day after day. Don't rush to any decisions."

You have no idea what you're talking about.

Mom continued in her concerned mom voice, "I've known Joanna for years, and I think the world of her. She's grown up in a very difficult situation, and, given that, she's amazingly well-adjusted. She's overcome a lot of challenges, and I admire her resilience, but she's going to have struggles you can't understand because you've grown up in a stable, loving family."

Someone who grew up in that same stable, loving family wants to fuck me.

"Love is all fireworks at your age. But when the fireworks dim, real love is work."

Fireworks with Kaitlyn. What an awesome image!

"There are days when I don't like your father, even though I still love him. Love is a choice; it's deciding every day to be totally committed to your other. I see Joanna as the type of person who can do that."

You have no fucking idea what you're talking about.

"What I'm saying is she's worth persevering for. Give her a second chance, and a third chance, and a fourth chance before you decide to do anything you might regret later. Okay?"

"Okay, Mom." I'll go back now to thinking about fucking my sister.

Mom stood up and smiled at me, her motherly message delivered. She went back into the lake house, leaving me to my thoughts.

I didn't have much time with them as Kaitlyn immediately came out after Mom went in. She sat down in the chair that Mom had occupied moments ago. "What did Mom say to you?"

"She's concerned because I haven't been my normal self recently."

Kaitlyn reached out and gave my hand a squeeze. "You're having a hard time with what we've been doing at night, and I admire you for that. So many guys would be 'The more making out the better'. Paul is certainly that way. But you're not comfortable making out with someone you're not committed to, are you?"

I was so thankful that Kaitlyn understood. "No, I'm not."

"Well, tonight is our last time since tomorrow night we have the big campfire." Our family tradition was that on the last night of vacation, we'd have a beach campfire where we'd tell stories, roast marshmallows and make s'mores. It was an evening of family fun.

"Last night," I said. What would happen tonight? Would Kaitlyn and I fuck?

"When I told you last night that I wanted you to fuck me, what did you think of that? Did it appeal to you?"

My thoughts were instantly scrambled as I both wanted to fuck Kaitlyn and was repulsed by the idea. I once again wrestled with my desire and my disgust at my desire. What kind of guy wants to fuck his sister? Particularly when he's got a girlfriend?

"Kaitlyn, I'm your brother."

Kaitlyn gave me a small, knowing smile. "And I'm your sister. Last night, did the idea of fucking me appeal to you?"

Why was Kaitlyn asking me this now? What was the point? It wasn't like we were going to fuck while Mom and Dad were "napping".

I had the feeling she was going to keep asking me until I answered her. I tried to think of an answer that wasn't really an answer, but I realized that Kaitlyn wouldn't accept one of those.

"Yes, it appealed to me. But I'm still Joanna's boyfriend."

Kaitlyn patted my arm. "You are. And you're a great boyfriend to her. I wish to God I had a boyfriend like you." Kaitlyn had a wistful look on her face. Then she pulled back her hand as her face turned serious. "Which is why I came out here. I told Paul to wait for me in our room. When I leave you, I'll go in and break up with him. I'll tell him that he needs to pack up his stuff, and that you'll take him back to our house."

"Holy shit!" I just about had a heart attack. This was not the news I was expecting. This was absolutely not the news I was expecting. "I didn't see this coming."

"I've told you that I had almost had it with Paul. This morning, I decided to pull the plug." Kaitlyn leaned forward. "You have to take him home. If Dad or Mom go with you, Paul will probably blab about what we did during their walks. I don't want Mom and Dad to ever know about that. So I'll go into our bedroom, give him the news, and then I'll come out and you go in. I'll tell Mom and Dad. You need to get Paul out of here as quickly and gracefully as possible."

I was stunned. Nothing in how Kaitlyn had acted on the boat had foreshadowed this. Well, she had kept her conversations with Paul brief and had spent as much time with me as with him. But they hadn't argued. She hadn't seemed mad at him. And now, BOOM!, she was sending him home.

"Does Joanna know you're breaking up with Paul and are sending him home?"

"Yes. We had a private chat while Mom made breakfast, and I discussed the possibility with her then. When we were clearing the dishes after lunch, I let her know I was going to do it."

The shock was wearing off, and though I was surprised by the decision, I liked it. Kaitlyn wanted to get Paul out of here as quickly as possible, and I could see the wisdom in that. "Okay. Let's do it."

We stood up and went inside. I dumped the remains of my lunch in the trash and put my dish into the dishwasher. I walked over to Kaitlyn's bedroom door. When she came out, I went in.

After I closed the door, I looked at Paul. He was sitting on the bed with his hands on his head, stunned. "Do you know what Kaitlyn just told me?"

"That she's broken up with you, that she wants you to gather all your belongings and for me to take you home."

"Why? Why did she break up with me? She told me it was because of Total Galactic War. I've been playing it since before I met her. Why dump me now? We had a blast last night. We had a good time skiing this morning. Why now?"

I walked over and sat down in the one chair in the room. "I don't know. The more I know about women, the more I know that I don't know anything about women."

Paul laughed bitterly. "Truth. It was so good between Kaitlyn and me at college. And things have steadily fallen apart this summer. But I haven't changed, and she hasn't changed." He raised his hands. "What went wrong?"

"She hasn't told me anything." Bullshit, but it wasn't my job to tell Paul about his romantic failings. "But it doesn't matter. She's declared it's over. Time to pack up and move on. There'll be another girl. A good-looking guy like you will have another girlfriend in no time."

Paul grunted. He didn't seem in the mood for the plenty-of-fish-in-the-sea talk. "Joanna..."

He looked at me. He seemed to realize that I was the wrong person to discuss any possible outreach to Joanna. She was my girl, and I was glad things had gone no further between her and Paul than they had. They had gone too far, but they had gone too far between Kaitlyn and me as well.

"Let's get you home. It's been fun having you here, but you're Kaitlyn's guest, and I'm not going to argue with her about having you stay longer."

Paul sat there for a while thinking. Once again, I was very aware of our difference in size. If he wanted to vent his anger by beating the shit out of me, I was certain he could. I was not happy being put in this role by Kaitlyn. The things you do for family.

Then Paul shrugged. He got off the bed, grabbed his duffle bag and started loading clothes into it. "Tonight, I thought I'd get to see you and Kaitlyn fuck."

"She's my sister."

Paul's eyes lit up. "That's why I wanted to see the two of you fuck. A brother and sister fucking. It happens all the time in porn videos, but never in real life."

The way he said that, I expected him to add, It would have been something to tell my grandkids.

I decided silence was the best answer. I too had thought he'd get to see Kaitlyn and me fuck tonight. That was what everything pointed to.

Why had Kaitlyn asked me minutes ago if the idea of fucking her had appealed to me last night? By the time I drive home and back, it'll be after Mom and Dad have finished their walk. And tomorrow night, we wouldn't do anything because of the campfire. And then we'd be home. It made no sense. The more I knew about women, the more I knew that I don't know anything about women.

Paul had his stuff packed up. He picked up his duffle bag, and we left the room. Only Mom and Dad were visible when we came out. Dad looked like he was ready to join me in subduing Paul. I walked over to Dad, and he wordlessly handed me the keys. Paul and I went down the stairs, got in the minivan and headed home.

* * * *

For most of the drive, Paul told me about Total Galactic War. It was almost as exciting as listening to paint dry. But I'd rather listen to him talk about that instead of how my bitch sister had done him wrong.

After a couple of hours, we stopped at a convenience store. We bought sodas and snacks and got back into the minivan.

As I pulled out of the parking spot, Paul said, "I was going to fuck Joanna tonight, and I was going to get see a brother fuck his sister."

"No, that wasn't going to happen."

"Bullshit! I saw how Kaitlyn has been looking at you. And how you've been looking at her. You both want to fuck."

"I admit that Kaitlyn and I went well past what a brother and sister should do, but we did what we did because she and Joanna kept swapping back and forth. But Joanna told me last night that she and Kaitlyn had agreed that last night was as far as they would go. No fucking, no oral sex except with their boyfriend. Joanna likes being naughty, but not that naughty."

Paul grunted. It wasn't the answer he wanted to hear.

I asked, "Did Kaitlyn say anything to make you think she and I would fuck tonight?"

I heard Paul exhale angrily. "No," he said bitterly. "She told me the 'no fucking, no oral sex except with their boyfriend' too last night." He fumed quietly. "But you and her last night..."

"That's why you make rules ahead of time. We followed them last night, and we would have followed them tonight."

Paul was silent after that, but eventually started telling me about Total Galactic War. He was still telling me about it when we got to our house. I watched him put his duffle bag into his car and drive off, and then I headed back to the lake house.

* * * *

As I drove, I got angry. I had been so nice to Paul on the drive back to our house for fear that if I made him angry, he'd tell people about what Kaitlyn and I had done. I should have let him know that I thought he was a big jerk and that he deserved to be dumped by my sister.

And I was angry about what he had done with Joanna. She was mine. No one else should kiss her or suck on her tits. I shouldn't have let that happen. I had let it happen so I could do the same with Kaitlyn, but I shouldn't have been doing that either. Doing so left us vulnerable to blackmail from Paul.

I took a deep breath. "I'm sexually attracted to my sister. She's the sexiest person I know. I'd love to fuck her." There, I had said it. That was the truth I had been avoiding. And because I had been avoiding it, I hadn't been thinking straight. Now that I had set that down on the table, I could deal with it. And I had to deal with it. Kaitlyn wasn't going away. She was still Joanna's best friend and was going to spend a lot of time with us.

One thing I didn't understand was why Joanna had been so accepting of me making out with Kaitlyn. Didn't she feel possessive of me like I felt possessive of her? Why didn't it bother her that I made out with Kaitlyn as it bothered me that Paul made out with her? Was Joanna the kind of person that would want to swap with other couples? Was she into having casual sex with some guy so long as it didn't threaten our relationship?

I didn't think so. I more had the feeling that Joanna was willing to do what she did with Paul as a favor to Kaitlyn, so Kaitlyn could do the same with me. Joanna seemed to enjoy my making out with Kaitlyn and had encouraged me to do so. This led me back to wondering why she was so accepting of me making out with Kaitlyn. Was Joanna thinking she was giving me what I wanted? She could tell that Kaitlyn and I were sexually attracted to each other. Was she thinking she was doing me a favor by letting me act on that attraction while at the lake house? Then her making out with Paul was a sacrifice she was willing to make so that both Kaitlyn and I could have what we wanted.

I hadn't communicated well with Joanna, whereas she and Kaitlyn seemed to know what the other was thinking. And Kaitlyn had used that to get what she wanted, which was to make out madly with me and to get me to the point where I wanted to fuck her.

Did Kaitlyn want me to fuck her? Or was what she wanted was that I wanted to fuck her? Was that the conquest she was looking for? That she could get even her brother to want to fuck her? Was that why she asked me this morning if I wanted to fuck her last night?

That made a lot of sense. It was consistent with Joanna saying that she wouldn't fuck or have oral sex with Paul. Kaitlyn had wanted to see just how wild she could drive me, and Joanna had gone along as she thought it'd be harmless fun I'd enjoy. If Kaitlyn hadn't sent Paul home, then tonight she and I would have gone right up to the edge of having sex; she would have driven me so wild that I would have wanted to go all the way, and then Kaitlyn would have stopped me. And after that, she'd be able to hold over me that I had wanted to fuck her, but she hadn't let me.

What did I think of Joanna planning things with Kaitlyn behind my back? I was uncertain. Joanna liked surprising me with her naughtiness, and I had enjoyed her surprises. If Joanna thought that letting me and Kaitlyn make out was a way of making both of us happy, then her planning things with Kaitlyn was a good thing. But I felt like Joanna and Kaitlyn had planned to do much more tonight than last night, and I was curious about exactly what they had planned. I'd ask Joanna when I got to the lake house.

I was tired of Kaitlyn's games. Yes, I had enjoyed kissing her and sucking on her tits. If we were the only two people in the world, I'd love to be her boyfriend and to fuck her every night. But we weren't, so our relationship had no future. All that physical pleasure just wound up leaving me confused, and now I was angry that Paul got to do the same things with Joanna. No more of that. When I got to the lake house, I'd tell Joanna that she was mine and I wanted only to be with her. If Kaitlyn tried to play up to me again, I'd tell her no and get Joanna to help make her stop.

* * * *

When I got to the lake house, everyone was still up but headed to bed immediately. Joanna and I got into bed with me on my back and Joanna on her side, snuggling up to me. I asked her quietly, "Why did Kaitlyn break up with Paul today?"

"I don't know. She refused to say."

"You two had a plan for today. What was it?"

"To play things by ear." Joanna nibbled my ear.

"Kaitlyn told Paul last night that there'd be no fucking, no oral sex except with a boyfriend. You told me that too."

Joanna tweaked one of my nipples with her finger. "That's what we agreed to yesterday when we went to town."

I had the feeling that Joanna and Kaitlyn had agreed to far more than that.

Joanna kissed me, scattering my thoughts. She rubbed her body against mine as she said, "I've missed you."

"I've missed--"

Joanna kissed me again, more passionately this time. Her hand went to my cock, which was beginning to stir.

"Joanna," I said that like a parent addressing a misbehaving child. "We shouldn't. You know the rules."

Joanna slipped off her panties. "You expect your naughty girl to follow the rules?"

I didn't have a good rebuttal to that. I wanted my naughty girl to not follow the rules. When she pulled on my boxers, I lifted my butt up so she could take them off me. I said, "We'll have to be quiet."

Joanna flashed me a smile, savoring my surrender to her. "Of course."
We weren't quiet, but we weren't loud. When we were done, I was laying on my back again with Joanna's head on my shoulder. I was happy. Very, very happy. It felt so good being with Joanna. She was unpredictable and never boring. It was like now that Kaitlyn had been taken off the table, I realized how perfect Joanna was for me.

I said, "I love you."

Joanna gave me a kiss on the cheek. "I love you too." She said it almost condescendingly.

"I'm serious, Joanna. I love you, and I want to be with you. I want to be with you for more than just the summer. You're fun to be with, I'm really comfortable with you, and you make me very happy. I want to see where our relationship goes long-term."

I expected Joanna to say something similar back to me. Instead, after a few moments, I heard a sob. I twisted around, so I could see Joanna's face, and I saw tears running down it. She said, "I never expected you'd say something like that to me." She threw herself on top of me and hugged me. "I love you, Brandon."

"I didn't mean to make you cry."

"Don't worry. These are good tears."

"So you are very happy?"

"Yes, Brandon. I'm very happy."

"Good, because I want to make you happy all the time." I guided Joanna's head back to my shoulder. "I love you." I felt her tears on my skin, but she didn't continue to cry. We drifted off to sleep.

* * * *

The next morning was Saturday, and we went out on the jet skis. Kaitlyn, Joanna and I took the big jet skis. We rotated around. When I was with Kaitlyn, nothing special happened. It was great that there wasn't any drama, that it was just the three of us having fun.

After lunch, Kaitlyn, Joanna and I made our way down to the chaise lounges. Joanna was in the center, holding my hand. She said to Kaitlyn, "Last night, Brandon told me the 'L' word."

Kaitlyn asked innocently, "Lesbian?"

Joanna cracked up. "No, he told me that he loved me."

"Congratulations. I told you two that you were a great couple."

I added, "And she told me that she loved me. It didn't take too much begging to get her to say it."

Joanna poked me in the ribs. "I told you I loved you right after you told me."

We lay down on the chaise lounges with Joanna in the center. I looked over her to ask Kaitlyn, "Why did you really break up with Paul yesterday after lunch? He said you told him that it was because of the game, but he's played the game the whole time he's dated you."

"That's probably true. But there's a huge 'but'. When we dated at college, we both lived in the dorms with roommates who never went home. When Paul's roommate would be gone for a while, we'd go over to his room for sex, and then I'd come back to my room. When my roommate would be gone for a while, Paul came over to my room. Sometimes, we'd ask one of our roommates to give us a couple of hours of privacy. We never slept together. I knew Paul played the game, but he always played it when we were apart."

That sounded reasonable.

"When Paul spent the night at our house the first time, we had sex and then I expected us to cuddle until we fell asleep. Instead, Paul pulled out his tablet and started playing his game. It bothered me. I really wanted to cuddle. I eventually rolled over and went to sleep."

I could see why that'd be disappointing. Cuddling time after sex was when I felt my most lovey-dovey. During the rosy post-sex glow last night was when I told Joanna I loved her.

"First thing the next morning Paul reached for his tablet and started playing his game. No good-morning kiss. No cuddling. Certainly no interest in morning sex. It bothered me. Not earth-shattering, but it bothered me. That weekend was the first time I was with Paul continuously, and I finally saw how much time he spent on his game. And it was way too much. Spending time playing the game was more important than spending time with me. I realized that at school he hadn't spent as much time with me as I had wanted not because he was studying but because he was playing his game." Kaitlyn sighed in frustration. "I really enjoyed being with Paul when he was focused on me. But I grew to hate being with him when he played his game."

Joanna said, "And his game addiction was a huge problem this week. He kept pulling away to play when the rest of us obviously disapproved of him doing so."

"You're right," Kaitlyn said. "I had told him before the trip that things had been going downhill for us all summer, and that we needed to recapture the magic this week. But his game addiction upset me more this week than ever before."

"Why not ride it out for the few days left?" I asked. "Why end it after lunch yesterday?" Why ask me if fucking her appealed to me?

"Thursday night, I had a great time. I was so in the mood when Paul and I went to our bedroom. We had great sex. And then, he didn't reach for his tablet right away after we were done. The first time ever. And he didn't reach for it because he wanted to know if Brandon and I were going to fuck the next night. I told him that Joanna and I had agreed that we would only fuck or have oral sex with our boyfriends. He wouldn't let it go. He kept saying, 'I know you want to fuck Brandon and that Brandon wants to fuck you.' It really pissed me off. I eventually told him to shut up and play his stupid game."

Ouch! That was consistent with what Paul had told me in the car. He had seemed obsessed with the idea of watching me and Kaitlyn have sex.

"As I went to sleep, I thought about breaking up with Paul the next morning. But breaking up with him would ruin the day for everyone. I decided to try to make it work for the few days that were left. But on the boat, he kept bringing up that he wanted to see Brandon and me fuck. I kept trying to laugh it off and change the subject, but it didn't work."

Joanna said, "He kept telling me how much he looked forward to fucking me that night. We had made that rule, but I didn't know if the two of you wanted to set it aside for the last night. So I didn't tell Paul no, and I didn't tell him yes."

"On the boat, I decided to pull the plug on everything," said Kaitlyn. "I had some plans for last night, but they weren't going to work with Paul wanting to fuck Joanna while watching Brandon and me fuck. Rather than have a disastrous evening, I decided to send Paul home." Kaitlyn got up and came over to me with arms open. I sat up, and she hugged me. "Thanks for handling that yesterday. Any problems?"

"Not really. I was surprised that Paul hadn't been angrier. I was expecting him to lash out at least somewhat, and he didn't."

Kaitlyn said, "I think it's because he knows he's addicted to the game, and his addiction was what ruined our relationship. He probably didn't want to talk about that, but I think it's why he was as willing as he was to accept being sent home."

I nodded. That all made sense. But I felt like something was missing, that Kaitlyn was holding back on me. I was sure that every word she told me was true, but what she had left out would have told a different story.

Joanna was sitting up too now. Kaitlyn sat down next to her and gave her a side hug. "And thanks for your support this week."

Joanna patted Kaitlyn's arm. "No problem. If it wasn't for you, I wouldn't have Brandon as a boyfriend who loves me."

Kaitlyn ended the hug and brought her hands together in front of her in a let's-talk-business position. "Now that you're in love, I think you two should sublet an apartment for the rest of the summer."

"What?" I said. "We just said 'I love you' last night. That's way too fast, Kaitlyn."

"I know it sounds fast, but if you're going to live together this summer, you should do so now. If you wait longer, you'll probably miss the chance to do so. You will live with Joanna this fall at college, right?"

I hadn't considered it. "The last I heard, the plan for college was you and Joanna getting a two-bedroom apartment together. I'd get an apartment with a friend. I'm fine with that plan."

Kaitlyn gave me one of her you're-being-stupid looks. "And how long until you spend the night with Joanna? Probably the first night, right? How long until you're spending all your nights with Joanna? Two months? A month? And then you'd be stuck paying for an apartment that you aren't using. It'd be a huge waste of money."

"I told Joanna I loved her last night. I'm not ready to commit to living together yet. I want more time together before taking that step."

Kaitlyn looked frustrated. "You have to plan to succeed. You have to take the leap of faith that you and Joanna will make it as a couple for you and Joanna to make it as a couple. Money will be tight for the two of you. Her mom gives her no financial support. If Joanna has an unexpected expense, she has nothing to fall back on. Financial struggles are the kiss of death for most relationships. To put you and Joanna in the best financial situation, you need to commit now to living with her in the fall. You need to assume that your love will grow over the summer for your love to be able to grow in the fall."

I thought over what Kaitlyn said. It was a lot to process, but it also made a lot of sense. I was not one who thought a lot about the future. I was content to let things develop at their own pace. But getting an apartment and then not using it made no sense. Money would be tight, and apartments were expensive.

I looked at Joanna. She had her head down. I could tell she wasn't going to interrupt. It was up to me to make the first move about living together, just like it had been up to me to say 'I love you' first.

"What do you think, Joanna? Would you like to live with me this fall?"

Joanna smiled widely. "I'd love to live with you this fall."

Kaitlyn said, "That's wonderful. But I still think you should sublet an apartment this summer."

"Why would we get an apartment this summer?" I asked. I felt myself getting angry. Kaitlyn was pushing too much. Having Joanna and me commit to living together in the fall should have been enough for her.

"Because if you're going to live together this fall, you might as well start living together now where you can get a lot of support for setting up a household. Mom and Dad have lots of dishes and linens that they'd be willing to lend. You'll have the time to go to yard sales to look for stuff."

I said, "Us living together now is too fast."

"Setting that aside, why not?"

"I'm not setting that aside. It's too fast. Mom and Dad aren't going to accept it. Joanna's mom isn't going to accept it. It will be a big enough shock to them when we tell them that we are planning on living together in the fall."

Kaitlyn raised her eyebrows. "Do you really think Joanna's mom will give a flip if she moves in with some guy?"

Joanna said, "No. She won't." I was a little surprised she had chimed in, as this talk had mostly been an argument between Kaitlyn and me. "She'll be unhappy that I won't be around to do the cleaning and laundry, she'll miss the two hundred a month I pay toward rent, but that's it." Joanna thought for a moment. "I like the idea of living with Brandon now, but your parents won't approve of it. And we'd really need their support to move in."

"My mom loves you, Joanna. She's thrilled you're dating Brandon. She's not going to disapprove of you two moving in together. She and Dad will support you two in doing so." Kaitlyn leaned forward. "Let me tell you something that happened earlier this summer. Paul didn't like staying at my parents' house. He asked me about getting an apartment for the two of us. He'd pay two-thirds of the rent. I talked to Mom about it. She wasn't thrilled about it, but she said I was an adult and could make my own decisions. As Mom and Dad only pay a fixed amount of my college expenses, the net result of my getting an apartment with Paul would have been that I'd wind up owing more on my student loans when I graduate. I looked into doing it. What Paul and I would have done is take over someone's lease. It happens all the time. There's even a section of Craiglists for doing so. I didn't do it because I didn't want to spend the money to be alone in an apartment most of the week. If Mom was fine with me living with Paul for the rest of the summer, she'll be totally fine with you and Brandon living together for the rest of the summer."

I said, "I'm not convinced."

"You two have been basically living together this week," added Kaitlyn. "Have you seen anything from Mom and Dad to indicate that they don't one hundred percent approve of you and Joanna being together?"

Kaitlyn was right - Joanna and I had effectively been living together this week, and my parents had been totally cool with it.

"Why not have Joanna live with me in my bedroom for the rest of the summer? We wouldn't have to pay rent that way. I'm pretty sure Mom and Dad would say yes. They were okay with Paul living with us on the weekends."

Kaitlyn said, "Yeah, Mom and Dad would probably be fine with it, but Joanna's mom won't believe that Mom and Dad are fine with it. She'll think that Joanna hates living with her and begged our parents to let her move in."

Joanna said, "That's exactly how she'd take it. I think she'd be fine with me moving into an apartment with Brandon, but not into his parent's house. I love my mom. She's not the best mom in the world, but she loves me, and she's done the best for me that she can. I'm not going to do anything she'd take as an insult."

I wasn't going to let Kaitlyn win this argument. She had played too many games with me this week. I felt like she had a hidden agenda; that she wasn't just arguing for what she thought would be best for Joanna, and that the three of us living together was something she'd directly benefit from, but she wasn't saying how.

"Joanna and I don't have the money to live together this summer. We need to save all our money for the fall. You said so yourself. The better financial shape we're in when we move in together, the more likely living together will be successful. If we lived together this summer, that would mean that Joanna would have to come up with her share of a security deposit and one month's rent on TWO apartments." I turned to Joanna. "Have you saved up that much money?"

"I have. I've saved up quite a bit."

That was a deflating answer. I thought of the old maxim that a lawyer should never ask a question in court they don't know the answer to.

"How about this," said Kaitlyn. "To cut Joanna's share of the summer apartment, I'll live with you and her. We'll get a two-bedroom apartment. Then as she is using one-half of one bedroom, she'll only pay twenty-five percent of the rent. Brandon, you and I will pay the rest."

I countered with, "Where are you and I going to get the money to live with Joanna for the summer? Doesn't it make more sense for us to live at home and save our money for when we get to college?"

"I wasn't willing to spend the money to have an apartment with Paul for the summer. I'm willing to spend the money for you and Joanna to live together. And I think it'll be a lot of fun living with you. Are you willing to spend the money to live with Joanna for the rest of the summer?"

Kaitlyn had put me in a position where I'd be a bad guy to say no; where it'd look like I loved Joanna less than Kaitlyn did. I didn't like it. I felt like Kaitlyn was manipulating me.

"I still think the best plan is for all three of us to live at our homes and save our money for the fall."

* * * *

That night was our traditional campfire, and I opened the campfire by telling everyone that I loved Joanna and was planning on living with her at college. Mom ran over and hugged her. To say Mom and Dad responded positively would be an understatement. We spent a lot of time talking about our plans for college.

We took turns sharing memories as we roasted marshmallows and made s'mores. We made fun of Paul quite a bit. Joanna didn't share as much as the rest of us. As we were wrapping up our stories, Joanna said, "Thanks for making me feel like a part of your family."

Mom went over and hugged Joanna again. "I hope someday you are part of our family."

When Mom released her, I pulled Joanna into a hug from behind.

Kaitlyn said to Mom, "You're obviously okay with Joanna and Brandon living together this fall. We discussed a bit about the three of us living together this summer. It was just a discussion, but Brandon and Joanna wouldn't want to live together this summer without your approval. Would you be okay with that?"

Mom shrugged. "You're adults; you can do as you want. There's not a big difference between you living together this summer versus this fall."

I was ticked that Kaitlyn had brought this up. "It was just a discussion. We have no plans to live together this summer."

* * * *

After breakfast the next morning, we put all of the aquatic equipment into the boat house. We cleaned up the lake house for whoever used it next while loading up the minivan and then headed out.

As there was nothing else to talk about, the five of us discussed Joanna and I living together this fall; where we'd get the furniture and the other things we needed for the apartment. Mom volunteered to lend us plates, silverware, and cookware.

Joanna said, "I want to do the cooking!"

"Joanna," said Kaitlyn, "You've learned how to get out the ingredients and how to cut things up, but have you ever made a meal from a recipe before?"

"No. But I want to learn." She looked at my mom. "I feel like a good wife should know how to cook. And I intend to be a good wife someday."

We got home in the afternoon. Once the minivan was unloaded, I took Joanna to her apartment and dropped her off. "Do you want to go out for dinner?"

"No. I want to spend the evening with my mom. I'll see you Monday night."

I kissed Joanna. "See you then."

Once I got back to the house, I put my stuff away and then went to Kaitlyn's bedroom. I closed the door as I entered. It was unusual for Kaitlyn or me to close our doors, but I didn't want our parents to hear this conversation. "Kaitlyn, I'd like to talk to you about our week at the lake house."

Kaitlyn pointed me to sit down on her bed. She sat down in her chair and said, "Let me start this by apologizing. I lied to you at the lake house. I was very selfish this week. I hope I didn't damage your relationship with Joanna, and I'm very glad it ended with you two deciding to live together in the fall."

I was surprised. I had intended to talk about how we went way over the line while Mom and Dad took their nightly walk. "When did you lie to me?"

"Let me back up a bit. When you kissed my neck Sunday night, it was electric. A kiss had never affected me that strongly before. I loved it. I absolutely loved it. And I wanted more. I've always had something of a crush on you, and your kissing me blew that crush up. When Paul made love to me that night, I imagined it was you. And I wanted it to be you. I was done with Paul at that moment. I should have sent him home the next morning."

"But you didn't."

"I didn't think of it. Before the trip, I was leaning toward giving Paul one last chance and then breaking up with him after the trip if things didn't improve. After you kissed my neck, I decided to definitely break up with him after the week. So I put on my sexiest bikini and showed off my tits to you. I loved doing that. After lunch, I asked Joanna if she'd be okay with you kissing me again, and she said she was. That night, I wore my sexiest bra and panties for you. As Joanna and I changed, I joked about her and I taking our tops off after you had kissed my neck and showing you and Paul our tits to really get you two fired up. Joanna laughed, but I think she knew that's what I wanted to do."

"And we did that."

"And I loved it. I loved showing you my tits. And you seemed to love seeing my tits. I felt like you felt toward me like I felt toward you, but you weren't willing to embrace those feelings like I was. And I wanted to explore those feelings more. I wanted to kiss you. So the next day, I intentionally didn't bring the sunscreen spray, so I could ask you to apply lotion to me. I loved the feel of your hands on me. And then I told my first lie - that I was thinking of breaking up with Paul at the end of the week. I acted like it was a possibility and not a certainty. I got Joanna to suggest her helping to teach Paul to slow down. I didn't care about teaching Paul anything. It was all an excuse so I could kiss you."
"And we kissed."

"And it was awesome. I never enjoyed kissing a guy that much. The whole time that night I had sex with Paul, I imagined it was you. I began thinking about you and me being boyfriend-girlfriend. It was all I could think about. The next day, I dropped a bunch of hints to you that I wanted to be your girlfriend. You didn't seem to pick up on any."

"That was Wednesday, right?"

"Yes."

"Yeah, I didn't pick up on any hints that you wanted me to be your girlfriend."

"That night, I joked to Joanna about letting the other guy feel our tits. Again, I think she knew I wasn't joking. She got Paul to tell you to feel my tits. And I was in heaven. Kissing you while you touched my tits was the most erotic thing ever. And I wanted you as my boyfriend even more."

Replaying the week had me hard. It was interesting hearing Kaitlyn's side of it. "What did Joanna think of us making out? What she'd think about making out with Paul?"

"She was fine with us making out." Kaitlyn paused for a bit. "You have to realize that Joanna and I have been close for a very long time. So now, we don't have to say a lot. She knew I had a crush on you. She knew I was enjoying kissing you. I think she knew I was lying when I was lying, and that what I really wanted to do was make out with you. So we didn't really talk about it. She loved dressing up sexily. She enjoyed planning what we were going to do each night. I'd make a joke about what I wanted to do, and then she'd let me do it. She even worked to make it happen. She wanted me to do what made me happy, and she trusted me to not hurt her in doing so. So we didn't really talk about you and me making out." That made some sense. "As for making out with Paul, we didn't discuss that either. I think she liked it, but she liked it because it was a piece in a larger whole. It was part of being naughty and letting me have what I wanted. Paul was very nice to her, but she vastly preferred you to him."

"Okay. Then on Thursday?"

"On Thursday-" Kaitlyn's phone rang. She looked at it, and I could see that it was Joanna calling. Kaitlyn answered it with, "Hey! Brandon and I are talking about the fun the three of us had at the lake." Kaitlyn listened and her face quickly turned serious. She nodded her head a couple of times. "That was the right thing to tell her." She listened some more. "Of course. We'll do it. I'll talk to Brandon. I hope he'll agree, but if he doesn't, we'll go forward with just you and me." Kaitlyn listened some more. She was smiling now. "You'd do the same for me." Kaitlyn listened for a bit more. "Let me go." A brief listen. "Bye."

Kaitlyn set her phone down and looked over at me. "Big news. The guy her mom has been dating moved in while we were at the lake house. He's a little creepy, and Joanna is not comfortable living there with him. So she wants to sublet an apartment for the summer. Our plan was always that if he moved in, we'd get an apartment. She told her mom about you telling her that you loved her and that you wanted to live with her. She then told her mom that you wanted her to live with you right away, and that you were looking for a summer sublet for the three of us."

"Basically what I rejected yesterday."

"Yeah, but things have changed. She needs to move out. If you don't want to live with us, that's okay; we'll just say that you are. It's not like her mom will check. You're just an excuse, so she can gracefully move out. She wants this relationship to work for her mom. Life is so much better for her when there's two paychecks coming into the household. Joanna and her mom have been living life on the edge for the last two years. Lots of dinners of beans and rice. Driving as little as possible because there's no money to fix the car if there's car trouble. Shopping at Goodwill and sewing their work clothes. Or not having any new work clothes. If all the guy does is pay half the rent and groceries, it'd make a huge difference. And this guy is fifty, so maybe he's ready to settle down and behave."

"Why does Joanna need to move out?"

"She had to beat off several assaults from her mom's prior boyfriend. Whenever she thought her mom might leave her alone with that loser, she'd figure out a way to get out of the apartment before her mom left. She spent a huge amount of time doing homework over here. I'd suggest we'd go shopping whenever she'd say a certain code word. It was a very, very scary time for her. This guy may never make a move on her, but the idea of being alone in the apartment with him brings back all the trauma of living with the prior boyfriend."

That sounded absolutely awful. "Okay. I guess we'll be living with Joanna as soon as possible."

"That's great. Kaitlyn made a pushing gesture with her hands. "Setting all that aside, I think her living with you this summer is the best thing for hers and your relationship."

I furrowed my brow. "Why do you think that?"

"Look, you told her that you loved her, and I think that's great. It made her very happy. But she's had lots of guys tell her that they loved her. She needs to hear a lot more than words. She needs to see commitment. She's never had a guy who was committed to her. Her dad disappeared before she was two. All of her mom's boyfriends haven't stuck around for very long. Her boyfriends haven't lasted. My theory at the beginning of the summer was that when she didn't feel like her boyfriend wasn't committing to her, she'd start doing self-defeating behavior. That's why I pushed so early for you to agree to take her to the lake house."

I was confused. "Why was agreeing to take her to the lake house such a big deal?"

"Because it showed that you were committed to her; that you weren't going to drop her after a month. It also showed you were proud enough of having her as your girlfriend that you were willing to have her spend a week with our parents. The Friday that Paul came to our house for the first time, we talked about going to the lake house that evening. That was the first time you talked about her going to the lake house with you, wasn't it?"

I thought back. "I think so."

"The next Monday on the drive to work, I could tell a big difference with Joanna. At some point, she brought up that you were only dating her because I had forced you into it and that you didn't really like her; that you were just looking to have sex with her. She's had similar conversations with me about other boyfriends. In those conversations, I could see her feeling of self-worth plunge. But this time, I could push back. This time, I could say you were committed to her and proud to have her as a girlfriend. She pooh-poohed what I was saying, but I could see it affecting her. Telling our parents that you were committed to bringing her to the lake house raised her self-confidence and her feeling of self-worth."

I thought back to that time. "The next night after that was when we made love for the first time. She initiated it. I told her for the first time that night that I was her boyfriend. Our relationship really took off after that."

Kaitlyn nodded. "And she's been the happiest she's ever been since. She had a tangible commitment from you throughout this week, and I think she needed a new commitment from you to keep her feeling of self-worth up. If you had just said 'I love you' for the rest of the summer with no new commitment, she'd think you're only saying that to have sex with her, as her other boyfriends had done."

"So you pushed me to commit to living with her this fall."

"Yes. At the lake house, she was still struggling with her self-worth. She still didn't think she was good enough for you to date her long-term. Telling her 'I love you' in no uncertain terms boosted her self-worth. But you committing to living with her this fall and telling our parents that you loved her and were going to live with her this fall really pushed up her self-worth. She knows you really love her now. She wouldn't have told her mom that you had asked her to live with you as soon as possible if she didn't think you'd back her up on that."

"So why this summer? Shouldn't committing to live together this fall be good enough?"

"It probably would be. But I think living together now will really cement in Joanna's head that you love her and are fully committed to her. You could have always backed out on living together this fall."

It was very odd having a conversation with my sister about how much Joanna loved me. I wasn't the greatest at having relationship discussions, but one would think that Joanna should be telling me this stuff. And speaking of Joanna telling me stuff... "Why didn't Joanna call me tonight instead of calling you?"

"Several reasons. Joanna isn't confrontational. She wasn't going to call you up and say she told her mom that the three of us were going to do what you rejected yesterday. She wanted me to convince you to do it. And that convincing involved discussing her mom's last loser, which is something she hates discussing. She probably wanted to keep the conversation brief, so she could get back to spending time with her mom and her boyfriend. She could do that with me, but not with you. And she trusts my judgment. She wanted to hear me agree that what she did was the right thing to do."

"Amazing." I shook my head. It was stunning to have Kaitlyn pull back the curtain and show just how close she and Joanna were and how her and Joanna's relationship worked. "You don't have to live with us."

"Joanna has already told her mom that the three of us will live together. I don't want to change from that. And I think a quarter of the rent is all Joanna can afford."

I thought that over. "That makes sense. Now, where were you in your telling me about what happened from your point of view at the lake house? Thursday?"

"Thursday. That was the day we went shopping. I was on such a high that day. The prior night, the four of us had had sex in the same room. While Paul was going down on me, it was easy to imagine you doing it to me with you being right there. The crazy dream of having you as my boyfriend was really strong. During the shopping trip was the first time I discussed with Joanna my feelings for you. And I got very selfish. Up to that point, Joanna had been fine with going along with me having fun with you. At shopping, I got her to agree with something I realize now she wasn't comfortable with. We agreed we'd never have sex with someone who wasn't our boyfriend; no oral either way and no fucking. But that gave me a huge amount of freedom in what I could do with you. And I was very confident that whatever I wanted to do, you'd want to do it too. I was so crazy about you that I was prepared to take advantage of my best friend's trust in me. And then Thursday night was a blast. I told you that I wanted to fuck you; that I wanted to feel you cum inside of me. And you didn't reject that. I could tell you wanted it too. I was on such a high after I told you that."

Kaitlyn was quiet after that, apparently reliving that high. I said, "And then...?"

"And then, Paul wanted to go into our bedroom and fuck. I didn't want to go. I didn't want to fuck him. I didn't want to touch him. I wanted you and only you. But I had to fuck him, and I did. And Paul was an ass that night. Afterward, I realized that I had gotten myself into a terrible place. I had just fucked a guy I now loathed and wanted out of my life. But I couldn't get him out of my life. I had to have him as my boyfriend to participate in naughty time while Mom and Dad did their evening walk. Yes, at the next naughty time, I could probably whip you up into such a frenzy of lust that you'd fuck me. But at what cost? If I fucked you, that meant Paul would fuck Joanna. Would you ever forgive her for that? The only thing I wanted was you as my boyfriend, but you hadn't shown any interest in being my boyfriend. And for you to be my boyfriend, that would mean Joanna giving you up as her boyfriend, and that would be bad for her as you were such a good boyfriend to her. Paul, the guy I loathed, had already seen me doing things with my brother that would be very embarrassing if it got out. Did I want him to see me fuck you? Did I want my best friend to fuck such a loser?"

Kaitlyn stopped talking, leaned back in her chair and folded her arms. "As much as I wanted you, the cost was too high. Over the morning, I decided to give up on it. And once I decided to give up on it, I didn't want Paul around. So I had you take him home. And I felt really guilty; not about anything we did - we're adults, and we both consented - but about taking advantage of Joanna's trust in me and possibly hurting her relationship with you." Kaitlyn rolled her chair over to me while leaning forward so she could put her hands on my knees. "Don't blame Joanna for anything she did with Paul. It was all my fault. She'll never do anything like that again because I'll never put her in a position where she needs to do something like that for my happiness. Please say you will."

I smiled. Kaitlyn's love for Joanna was touching. "I won't blame Joanna."

"Great. And once again, I'm sorry I lied to you and deceived you. I'm not sorry about anything I did with you. I loved it, and I think you enjoyed it. If I had the chance, I'd do it all over again."

I didn't know what to say to that. I was beginning to accept that I had loved making out with my sister too, but I wasn't ready to say that out loud. If I had the chance, would I do it all over again? Maybe.

Kaitlyn said, "How about this? You start searching for subleases. I'll go tell Mom and Dad the news about us living together this summer. Or would you prefer something else?"

I stood up. "No, that'll be fine."

* * * *

In my bedroom, I hit Craigslist and searched for sublets. I set a price range based on the apartments near my college. I found several sublet ads that were fully furnished and out of our price range. There were two ads for apartments in apartment complexes; one was for a nine-month sublease and the other was for a six-month sublease. Too long for us. The only ad that looked like it could work for us was a house undergoing major renovations. Only the two upstairs bedrooms and the kitchen were not under construction. It had a pool in the backyard and a nice patio. It was furnished, which would save us from having to buy furniture now. Contractors would be working on the house during the day. Seeing nothing better, I replied to the ad.

I gave Joanna a call. "Hey. I hear you want to live with me."

"I do."

"That's great, because I want to live with you." I told her about my search.

"That would do. I like the backyard pool and the patio. I'd like to spend a lot of our evenings just hanging out."

"I'd like that too."

"I'm sorry--"

"Don't be. There are a lot of good points about us living together now. I wasn't in the mood to let Kaitlyn push me as far as she wanted to, so I wasn't open to the idea of living with you this summer. I like the idea now. But it'll probably take a week to secure a place. Are you okay there? Or do you want to move in with me in my bedroom until we find an apartment?"

"I think I'm fine. I've got a good reason to spend every evening with you. I don't want it to be obvious that I don't want to live with Mom and her loser. Mom was surprised when I told her you wanted us to live together right away, but she accepted it. That being said, I'd like to move in this weekend."

"Okay. I'll do my best."

* * * *

The next morning, Kaitlyn and Joanna had an important conversation I'd hear about much later as they drove to work in Kaitlyn's car.

Joanna said, "Okay. Thursday afternoon when we went shopping, you talked me into being open about switching boyfriends. Thursday night was to be a test run. Everybody had a great time Thursday night. And then Friday morning, you told me you were having second thoughts about the switch. You told me to be friendly and flirty with Paul, and to tell you if he talked about being my boyfriend."

"And all he talked about was fucking you and seeing Brandon and me fuck."

"Yes. So you had Brandon take him home. Let me be clear - I'm very glad we didn't switch. I was very iffy about the switch but was willing to trust you. Then when Brandon got back to the lake house, he told me that he loved me, and it's been like a dream ever since. But what happened late Thursday night so that you called off the switch and instead sent Paul home?"

Kaitlyn sighed. "To be honest, exactly what I told you and Brandon. I had talked you into switching boyfriends. I thought that would be the hardest part of making the switch happen. Thursday night, it was electric between Brandon and me, so I was sure he'd go for the switch. It just came down to Paul. I felt he knew it was over between us. I had set him up with a replacement girlfriend. I even got him to sample the goods, so to speak. He was all fired up when we got to the bedroom. When we were done, all he had to say was that he wanted you, and we'd make the switch. I had lots of different conversation lines worked up. Hopefully, he'd see the obvious and say as he and I were about to break up, he wanted you to be his girlfriend. If instead he said that he wanted to fuck you, I'd say that you were only interested in fucking your boyfriend. And then I'd lead Paul to ask if you and I would switch boyfriends so he could fuck you. Etc, etc. But when we were done fucking, all Paul wanted to talk about was me fucking Brandon. That was not what I thought he'd want to talk about. It was not what I wanted to talk about. I didn't want to admit that I desperately wanted my brother as my boyfriend. I wanted it to be that I arranged for Paul to be with you, and that Brandon and I would be left together."

"We'd know that you were lovers, but we'd pretend to not know it."

"Exactly. You don't discuss a brother and sister being lovers in polite conversation. But Paul didn't get it. He didn't get that I was offering him a new girlfriend, but he had to show he wanted her. It was all about Brandon and me. That put me on the defensive, and Paul kept me on the defensive. Finally, I told him I didn't want to talk to him anymore, so he should play his stupid game."

"Then why didn't you tell me in the morning that everything was off?"

"Because I had come so close!" Kaitlyn slammed the steering wheel with her fist. "I wanted Brandon! I hoped Paul would come to his senses overnight, that he'd realize how great of a girlfriend you'd be." Kaitlyn touched Joanna's arm reassuringly. "I was not going to initiate the switch unless I was absolutely sure you'd be happy with Paul. Paul had to want you. He had to want to make you happy. He had to want to treat you the way you deserved to be treated. But he never said that. The whole morning on the boat, it was like he thought we'd swap partners when it came time for sex that night, and then I'd be his girlfriend again. The big dolt. I was so done with him. The only reason I hadn't sent him home sooner was because I needed him to be around. Once I knew he wouldn't cooperate, I had Brandon take him home." Kaitlyn came to a stop at a light and caught her breath. "I've come to realize that my plan not only was selfish but wouldn't work. It was way too dependent on Paul. So, I'm glad we didn't switch. Were you willing to switch with me just because you trusted me?"

"No. Well, sort of. The big thing was I felt that Brandon considered our relationship to be only for the summer. If I switched with you, then I'd be in a long-term relationship with Paul. And you'd be in a long-term relationship with Brandon. So I felt bad about agreeing to switch to Paul without breaking up with Brandon, but we'd all end up in the long-term relationships we wanted by doing so. Paul wouldn't be a great boyfriend like Brandon, but he'd be a good boyfriend. And I felt I was deserving of a good but not great boyfriend, so that was more likely to work long-term for me."
"You thought Paul would be a good boyfriend because I hadn't told you about his gaming addiction."

"Yeah. Not nice of you to leave that out."

"I know this will sound crazy, but I was going to take care of you. When you found out about Paul's gaming addiction and soured on him as I had done, I was going to offer to share Brandon with you. We'd share him equally. I know that sounds crazy, but I needed you to be Brandon's girlfriend. If Brandon and I were constantly going out just the two of us, it'd be weird. Particularly as we wouldn't be dating anyone else when we easily could. And it's really important to me that Brandon and I go to movies, restaurants, concerts, etc. But it wouldn't be weird if I tagged along with Brandon and his girlfriend who was my long-time best friend. That was my end game - sharing Brandon with you. It'd be a bitch getting Paul out of the picture, and you'd have to put up with his bullshit for probably the whole summer, but you're such a great friend I thought you'd be willing to do it."

Joanna laughed. "I don't know if I'm that great of a friend."

"I know. I can be absolutely evil at times. No way I should have expected you to do that. I'm glad I came to my senses and sent Paul home instead of initiating the swap. Things between you and Brandon have worked out great ever since. You're now quite the happy couple."

"We are," said Joanna dreamily. Then she asked with concern, "You're not going to tell Brandon we agreed to swap boyfriends, are you?"

"Of course not! Brandon doesn't need to know about that. I've learned my lesson from last week - I'll never do anything again to hurt your relationship with Brandon. My friendship with you is the anchor of my life. It makes me happy to see you happy, and Brandon makes you happy. I think I'll enjoy living with you and Brandon because I'll get to see how happy you are together every day."

"And it makes me happy to see you happy."

"And right now, I'm happy Paul is out of my life. The evenings at the lake were a lot of fun, but it sucked being with him all the rest of the time. It's great not having that drama anymore."

"I really enjoyed those evenings. I also enjoyed planning them with you, deciding with you what sexy clothes we'd wear, and getting dressed up."

"And braiding my hair! You came up with the best braiding designs."

"Thanks. And I enjoyed that too." Joanna was silent for a moment. "I think part of the reason I was willing to swap for Paul was that making out with him was so hot, but now I realize that why making out with him was so hot was the mood in the room; you were totally into making out with Brandon, and it was infectious. I doubt I would have enjoyed making out with Paul if we had been in separate rooms."

"Yeah, it was hot with all four of us making out in front of each other. What gave me the courage to make out with Brandon as I did was that I knew you were fine with it. Brandon resisted, and it was hot breaking through his resistance, but I wouldn't have been able to break through his resistance if you hadn't been there letting him know you were okay with it."

"I wish we had done it one more night," said Joanna wistfully. "Did you consider not sending Paul home so we could have had a replay of Thursday night on Friday?"

Kaitlyn made an awkward face. "Not really. I was too done with Paul. And if I had made out with Brandon again, I was going to fuck him. Which would have been fine if he was my boyfriend and you were Paul's girlfriend, but it wouldn't have been fine for Paul to fuck you if you were Brandon's girlfriend. So even a scenario where we made out for a while and then went to bedrooms so Paul couldn't see exactly what Brandon and I did wouldn't have worked."

"You're right. That wouldn't have worked."

When I got up, the people who posted the ad had responded to my reply, and I filled out their paperwork. I regularly refreshed the page all day and eventually something closer to what we wanted popped up. It was a little more than the budget I had set and was kind of out in the exurbs, but it looked like a nice, fairly new complex and the sublease expired at the end of August. I replied to the ad. I eventually got a response and made an appointment to see the apartment that evening.

Joanna, Kaitlyn and I went out to see the apartment. As we drove, we discussed how we were going to split up the responsibilities. Kaitlyn asked Joanna, "What do you want to do?"

"I want to do the cooking, pay the bills, make the shopping list, and keep the calendar for the apartment."

Kaitlyn asked me, "Do you want to do any of those things?"

"No."

"Fine. I think that's a lot. So how about Brandon and I try splitting the rest? We should make up a list of all the responsibilities and make sure that they are all assigned fairly evenly."

"Okay," I said.

Kaitlyn had a pad. She and Joanna brainstormed on responsibilities. I drove and listened.

When we got to the apartment, a woman in her twenties opened the door. "Come in. I'm Collette. And this is my son, Trevor." Her son looked three years old. She walked us around the apartment. "I broke up with my boyfriend this weekend, and he's moved out. I can't afford this apartment on my own, so I'm going to move in with my mom."

The apartment was nice. It looked only a few years old with marble counters and a well-laid-out kitchen. The master bedroom had its own bath. The second bedroom was an adequate size, and the second bathroom was down the hall from it. It was on the third floor and had a view of the parking lot.

Collette said as she showed us around, "The complex has very nice amenities. It's got two pools. One is family-oriented with a big shallow end and an outdoor kitchen. The other is for adults. There's a large fitness center and a nice clubhouse. They host events at the clubhouse regularly."

I looked at Joanna and Kaitlyn. Both of them had been nodding positively the whole time we walked through the apartment. I said, "I like it. What do you think?"

"I like it too."

"It's what we're looking for."

We made the arrangements with Collette. She'd arrange with the office for us to take over the sublease. We'd come up Saturday morning and sign all the paperwork at the office. She'd start moving out after that. She hoped to be out by Saturday afternoon. She'd then give us the keys, and we could move in.

As we walked out to the car, Joanna started bouncing for joy. "It's happening. It's actually happening." She kissed me. "We're going to be living in a place of our own."

* * * *

I got Saturday off from work. Dad rented a U-Haul while Kaitlyn, Joanna and I went to sign the paperwork to take over the lease. When everyone got back, we cleared almost everything out of Kaitlyn and my bedrooms. Once we had that done, we drove over to Joanna's apartment and got her stuff, which was mostly clothes. We drove back to our house and waited for Collette to call. Mom kept saying, "I'll miss you two so much" and "Your bedrooms look so sad now".

I said, "If you'd like, Mom, the three of us will come over for dinner once a week."

"You would?"

Kaitlyn said, "That's a great idea."

Joanna added, "I can show you what I've learned about cooking, and you can give me more lessons."

We quickly settled on Sunday night for us to come over for dinner.

When Collette called, the five of us went over to our new apartment. Mom and Joanna organized the kitchen while the rest of us concentrated on the bedrooms. We didn't have any furniture for the living room or dining room, but we'd buy that eventually. We ate delivered pizza as we worked. A little after nine, we had things well enough in hand that we wished my parents goodbye. Joanna and I put things away in our bedroom and bathroom until ten.

I said, "I'm tired."

"Me too."

"Let's go say goodnight to Kaitlyn and then hit the sack."

We went over to Kaitlyn's bedroom and each gave her a hug before heading back to our bedroom. I stripped down to my boxers. Joanna stripped down to her panties and put on a nightshirt. Would we make love tonight?

When we got into bed, I said, "Is my naughty girl happy to be sleeping with me again?"

"I'm too tired to be naughty tonight." Joanna crawled over next to me and put her head on my shoulder. "But I'm very happy to sleep with you tonight. This is like a dream come true for me." She kissed me on the cheek. "I love you."

I kissed her on the lips. "I love you too."

We cuddled a little more before drifting off to sleep.

* * * *

Sunday, I went back to work. While I was working, Joanna and Kaitlyn bought a used dining set and a couch. When I got off work, the three of us had dinner with my parents. That night, Joanna and I made love for the first time in our new place.

Over the next week, we did a variety of things, always all three of us. Monday, we went to the adult-oriented pool, swam and talked to some other adults. Tuesday, we used the fitness center. Wednesday, we went out to a movie. Thursday, we used the fitness center again. Friday, we went back to the pool. We spent a lot of time during the week sitting around the dining room table with our electronic amusements, talking and relaxing. It was very comfortable living together.

Saturday, Joanna had dinner waiting when I got home from work. It was a pasta, ground beef and tomato casserole that was one of my mom's old reliables. Kaitlyn made salads and biscuits. It was a good dinner. Afterward, we went to the pool and relaxed for a while. On the way back, Joanna said to Kaitlyn, "We might as well leave our bikini tops on and just change into shorts. I'll wear those terry cloth short-shorts if you do too."

"Sure."

We changed and headed to the dining room table as usual. Joanna got there first. She took two of the chairs and put them facing each other about six feet apart. She sat down in one as she indicated to Kaitlyn that she should sit down in the other. She then said to me, "Your naughty girl would like you to kiss her neck and shoulders tonight."

Suddenly, my heart was pounding in my chest. Joanna and Kaitlyn were dressed the same, just like the nights at the lake house. And now Joanna was asking me to kiss her neck in front of Kaitlyn, just like at the lake house. What was Joanna planning? She wasn't planning on doing something like at the lake house, was she?

I moved behind her and kissed down the right side of her neck and then across her right shoulder. I could taste the pool water on her as I did so. It was a struggle to go slowly. I wanted to see what Joanna had in mind. By saying naughty girl, she implied that she wanted to do something naughty tonight. She was going to want me to kiss Kaitlyn's neck and shoulders like I was kissing her, right?

When I got to the end of her right shoulder, Joanna said, "Now go do the same for Kaitlyn."

I looked at Kaitlyn as I walked over toward her. She had a look of anxiety and confusion. I guessed that Joanna hadn't told her what she was planning.

I pushed Kaitlyn's hair aside and kissed her neck. She gasped like the first time I had done it. I kissed a little lower on her neck and then again a little lower. I felt that sexual electricity between us beginning to build. I could taste the pool water on her too. It was good to feel her skin again with my lips.

Joanna asked, "Are you enjoying that, my best friend?"

Kaitlyn said in a controlled manner, "Yes."

"How much?"

I was kissing along Kaitlyn's shoulder now. She said a little angrily, "I love it, okay? I've loved it every time Brandon has done it to me."

When I reached the end of Kaitlyn's shoulder, I looked over at Joanna. She waved me back. I walked over to behind her. She said, "Take off my top, Brandon," as she raised her arms. I grabbed her bikini top and pulled it upward. I took it off her and dropped the damp top onto the floor. "Now play with my nipples while you do the other side."

I moved Joanna's hair and kissed down the left side of her neck. I brought my hands around in front of her and put them on her tits. As I reached the nape of her neck, I squeezed her nipples between my fingers. Joanna sucked in her breath. "That feels so good. It feels good to be naughty again. I like being naughty."

I slowly kissed along her shoulder, wondering how naughty Joanna wanted to be tonight.

Joanna reached up and scratched my head as she said, "I'm going to tell you both a secret tonight. You'll both probably think I'm a terrible person. I'm not as innocent as I seem."

When I reached the end of her shoulder, I started walking toward Kaitlyn. She had a hungry look now. I thought back to the last time we had had naughty time at the lake house, when Kaitlyn had told me she wanted to fuck me. She looked like she wanted me again.

When I got to Kaitlyn, she raised her arms in the air. I grabbed her bikini top and pulled it off of her. She dropped her arms, and I moved to her neck. As I did the first kiss, I cupped her tits with my hands. They felt so big in my hands. I loved their shape and feel. It was wonderful to feel them again.

Kaitlyn moaned as I kissed down her neck and squeezed her tits. She was allowing herself to get much more into it this time.

Joanna said, "The first time I went to your house, I thought it was the best house in the world. It was the kind of house I wished I had grown up in. And I loved your mom. I loved how she treated me. I was over with three other girls, each of whom had been over to your house lots of times. I was so envious of them. I wanted to come to your house all the time. I wanted to be your best friend. But how could I? I was this nothing-special poor kid."

I was torn. I wanted to hear what Joanna had to say. I felt she was sharing something important. But at the same time, I wanted to concentrate on kissing Kaitlyn and feeling her tits. When Paul had gone home, I had assumed the naughtiness was over, and I'd never get to touch Kaitlyn again like this. But now I was, and I was enjoying it immensely.

"And I became your best friend. Aren't I your best friend?"

I was almost at the end of Kaitlyn's shoulder now. She answered dreamily, "You are my best friend."

I finished kissing Kaitlyn and started walking over to Joanna. She got up and stood next to her chair, facing away from me. When I got to her, she said, "Get to your knees, Brandon." I dropped to my knees. "Now pull down my shorts slowly."

I grabbed her terry cloth short-shorts and slowly pulled them down. As I did, Joanna sexily wiggled her ass back and forth. She was having fun. She was enjoying driving me crazy.

"You're so naughty, Joanna."

Joanna laughed as I stood up. "I am. I'm totally naughty." She indicated I should sit down in the chair. Once I sat down, she straddled my lap and said, "Suck on my tits, Brandon." I latched onto on her nipple. "Now squeeze my ass." I squeezed her ass with both hands as I sucked on her nipple. Joanna ran her fingers through my hair. "That feels so good. You're the best lover I've ever had, Brandon. You know how to touch me, how to get me excited." She continued running her fingers through my hair. I switched nipples. "But being naughty makes it all so much more exciting for me. I love being your naughty girl."

I continued sucking on Joanna's nipple while squeezing her sweet ass. And then Joanna pulled my head back, saying, "Kaitlyn's turn."

Joanna got off of me, and I walked over to Kaitlyn. She was standing next to her chair with her back to me, just like Joanna had. I got down on my knees and slowly pulled down her short-shorts. As I did, she swayed her hips sexily. When Joanna had wiggled her hips, it had been silly fun. With Kaitlyn, it was an erotic show.

Once Kaitlyn had stepped out of her shorts, Joanna said, "Kaitlyn, Brandon is overdressed. Would you please take off his shorts?"

Wordlessly, Kaitlyn dropped to her knees in front of me. She grabbed my shorts and slowly pulled them down. The whole time, she stared at my rock-hard cock that was a few inches in front of her. The last time at the lake house, she had said she wanted my cock inside of her. And she wanted me to cum inside of her. I had no doubt that was still her desire.

Once my shorts were off, I sat down on the chair. Kaitlyn immediately straddled me. I sucked her hard nipple into my mouth while I squeezed her firm, well-rounded ass.

Joanna said, "After that first visit. I tried to spend as much time as I could with Kaitlyn. But she wasn't that interested in me. And why should she? And then one day, it happened. She said something about you, Brandon. Something like, 'He's so good-looking. No wonder he always has a girlfriend.' She was immediately embarrassed by it. She added, 'But he's such a jerk at times.' I could tell she didn't really mean the last part; it was just something to deflect away from that she thought her brother was very good-looking. After we parted ways, I thought and thought about it. And I came up with a plan. I'd regularly ask her about you. I'd try to get her to say complimentary things about you. And I'd let her know that I thought that was fine. I'd be the one friend she could talk about her brother with. That was how I could get Kaitlyn to want to talk to me."

Again, I was torn between wanting to pay attention to Joanna's story and to focus on enjoying Kaitlyn's body. Was this a one-time thing? Was this the last time I'd get to suck on Kaitlyn's tits and squeeze her ass? Did I want it to be the last time? I loved Joanna, and I wanted to be with her forever. But I also loved Kaitlyn and lusted for her.

Joanna said, "My turn."

Kaitlyn got off of me. I stood up and walked over toward Joanna, who was standing in front of her chair. She said, "Get down on your knees and take off my panties."

I dropped to my knees, grabbed Joanna's panties and slowly pulled them down. I'd lived with Joanna for a week now, but there was still something magically about seeing her pussy. I could smell her sexual excitement. Yet at the same time, what most filled my head was the prospect of seeing my sister's pussy this close very soon.

After Joanna stepped out of her panties, she sat down on the edge of the chair and spread her legs wide. "Eat me, Brandon." I shuffled over to Joanna and brought my mouth to her pussy. I parted her pussy lips with my tongue and took a lick. I was not surprised to find that she was very wet.

"That's it, Brandon. Show your sister what a great pussylicker you are. Make her jealous that you're eating me out and not her. You know she wants you to lick her pussy like this."

I attacked Joanna with relish. I slurped up her juices as quickly as I could. I had learned the subtle signs she gave to express her sexual pleasure, and she was giving off a lot of them. And the more my tongue pleased her, the more I wanted to give her more pleasure. At the same time, I wondered what was next. Was I going to eat out Kaitlyn? I had never gone that far with her. Why would Joanna want me to go that far now? But it would be almost cruel of Joanna to leave Kaitlyn high and dry after having her watch me pleasure her.

When I shifted my focus to her clit, Joanna responded by running her fingers through my hair. I continued my feverish assault until she suddenly clamped my head with both hands. She quietly came as I slowed my tongue work. I could feel that my face was coated with her juices.

I stood up, and, to my surprise, so did Joanna. She gave me a small push. "Go on. It's Kaitlyn's turn."

Kaitlyn was standing also. I walked over to her and dropped to my knees. I had hoped Kaitlyn would be wearing some sexy panties, but she was wearing a plain pink, cotton pair. Another sign that tonight had been a complete surprise to her. I grabbed her panties and began pulling them down. Kaitlyn's bush was much more trimmed back than Joanna's and a lighter shade of brown. I couldn't smell her excitement, but that wasn't surprising as my face was coated with Joanna's juices.
Joanna's voice right behind me startled me. "Kaitlyn, Brandon is the only one who's not naked. Would you remedy that please?"

As Kaitlyn and I switched positions, Joanna walked away from us. Joanna said, "My plan for getting Kaitlyn to talk to me worked great. I was surprised at how well it worked. In no time, Kaitlyn was frequently inviting me over to talk about you, Brandon. I knew she had feelings for you, and I did everything in my power to encourage them. The more she crushed on you, the more she valued my friendship. She became my champion, taking me to almost all the gatherings she was invited to. When my relationships turned disastrous, she was always there to pick me up."

While Joanna said that, Kaitlyn had slowly pulled down my boxers. She alternated between looking at my hard cock and looking up at me with a big smile on her face. Once I stepped out of my boxers, I took her hand and helped her up off the floor and onto the chair.

Joanna was now standing behind Kaitlyn's chair. She said to me, "Go ahead. Go down on my best friend. Make her happy." Then to Kaitlyn, "This is what you want. All those times we talked about Brandon. You wanted him to make you cum, didn't you?" Kaitlyn spread her legs wide as I moved close to her pussy. I saw Joanna had a comb in her hand, and she started combing Kaitlyn's hair. "And I encouraged her to want that. So it's really on me that she so badly wants you."

I looked up at Kaitlyn and took a moment to admire her beauty. She had a light tan now, so the paleness of her crotch and tits provided an interesting contrast. I loved her curves, her smooth skin, her ample tits, her pretty face, and her gorgeous hair. I gave her a smile of appreciation and moved my mouth to her pussy.

I parted Kaitlyn's pussy lips and took my first taste of her juices, causing her to moan loudly. I liked Kaitlyn's taste; it was slightly lighter than Joanna's. I slowly explored her pussy with my tongue while listening to how she reacted. She was so much louder than Joanna. Several times at the lake house, I had felt like I had been making Kaitlyn moan when I was having sex with Joanna, but it was much, much better now that I knew Kaitlyn's every moan really was because of me.

Incredibly, Joanna continued talking while I ate out my sister in front of her. "When Kaitlyn asked you to ask me out, I knew I didn't have a chance with you, that our relationship would last only for the summer like you promised Kaitlyn. And then to my surprise, we started having a lot of fun together. But I always felt like I was just a fun girl to you; that you never took me seriously. You never talked about your feelings with me or the future. So at the lake house, I found myself encouraging you to be involved with your sister. It was like I wanted to see if what worked with Kaitlyn would work with you. I suggested you kiss on Kaitlyn's neck and shoulder as a lesson for Paul. Kaitlyn loved you doing that, as I knew she would, but you enjoyed it too. But you didn't want to admit you enjoyed it."

I licked down Kaitlyn's pussy, concentrating on the outer lips. Her slightly rough skin felt good on my tongue. I planned to drive her wild by licking every inch of her pussy before making her cum. When I reached the bottom of her pussy, I lapped up the flood of juices she was producing. I moved over to the other lip and slowly licked my way up. When I got to the top, I teased her clit for a little while, testing Kaitlyn's response to different ways of stimulating her clit with my tongue. Kaitlyn had her hands on my head and ran her fingers through my hair as she continued to loudly moan.

"Kaitlyn wanted to do more with you, and I let her talk me into it. I could tell how much you were attracted to her, which made me a little jealous. But I felt like you really paid attention to what I said for the first time as you struggled with your emotions. And you were appreciative that I didn't judge you for what you did with Kaitlyn. I felt your feelings for me deepened because I was okay with you having feelings for Kaitlyn."

I made another lap around Kaitlyn's pussy and went back to her clit. Kaitlyn was moaning constantly now. She seemed to react the strongest when I licked the left side of her clit. Her hands were off my head now as she lay back and enjoyed me tonguing her closer and closer to an orgasm. She seemed in heaven.

"I didn't know how things would play out. After the week, would you go back to treating me as just your fun girl? Or was this the start of a new phase in our relationship? I let Kaitlyn talk me into escalating things to find out."

I looked up at Joanna. She was combing Kaitlyn's hair, like she had done so many times before. There was something crazy about her doing such a mundane thing while I ate out my sister as Joanna spilled secrets. I made another lap around Kaitlyn's pussy before deciding the outer lips were stimulated enough, and it was time to focus on her clit.

"And then Kaitlyn sent Paul home, and you told me that you loved me. And the way you told me that made it clear that I wasn't just your fun girl, but someone you wanted to be with long-term. And then Kaitlyn brought up us living together. You surprised me by saying you wanted to live with me at college. I was so happy."

I danced the tip of my tongue around the left side of Kaitlyn's clit, trying different angles to see how she'd respond. She seemed to respond enthusiastically to everything I did. "Oh! Oh! Oh!" I suspected she was close to cumming.

"I got everything I wanted, thanks to my best friend. But my best friend still didn't get what she wanted most."

Kaitlyn gripped my head suddenly. I continued to flick her clit as she let out a massive "YYYEEEEESSS!" She bucked her crotch erratically as she came. I had made my sister cum! I stopped my licking but kept my face in her pussy as she continued to spasm. When she stopped, I pulled back and sat on my haunches. I looked up and saw a euphoric look on Kaitlyn's face. I smiled. She said, "That was incredible."

Joanna continued combing Kaitlyn's hair like nothing out of the ordinary was going on. "I know both of you love each other, and I know both of you love me. And I think my acceptance of you loving each other has made you two love me more." Joanna stopped combing Kaitlyn's hair. She tucked the comb under one of her arms and quickly braided Kaitlyn's hair. She formed it into a complex design that looked like a crown on the front and sides, and a waterfall in the back. It was like Joanna wanted Kaitlyn to look her most gorgeous. Joanna looked down at me and said, "I'm going to our bedroom. Give my best friend what she wants the most in the world. And then come to bed with me."

Joanna walked off. I stood up and took Kaitlyn's hand. She stood up and asked, "Do you want to do this?"

"Yes. You're my sister, but you're also a beautiful woman that I love. I enjoy being with you. You're great to live with. I very much want to know what it's like to make love to you."

Kaitlyn smiled, and we walked hand in hand toward her bedroom. When we got there, I pulled back the covers as she got out a beach towel. Once she had spread the towel out, she said, "I want to be on top."

"Okay."

I laid down on my back. Kaitlyn clambered over me, positioning my cock between her pussy lips. She then put her hands outside each of my shoulders and slowly lowered her head until our lips met. As we kissed, Kaitlyn pulled her hips forward and back, sliding her pussy along my cock. I could feel her wetness coating my cock as she did so. My desire to fuck my sister had been building since it seemed like a possibility when Joanna told me to kiss her neck. I had thought I couldn't want Kaitlyn much more when I professed my love for her, but she was driving my lust higher and higher as she slid her pussy along my cock.

Kaitlyn reached back with one hand guided my cock inside of her. She slid back again, and this time my cock went deep within her. She felt amazing. She was so wet and yet so tight. I loved it as every inch slid into her until I was buried completely inside of her.

Kaitlyn pushed herself up, shifted her position, and kept straightening until she was upright with her hands behind her head, elbows high and to the side. She thrust out her chest for me to admire.

I said, "You look like a goddess."

Kaitlyn smiled, and held the position for a few moments before leaning forward while putting her hands on my shoulders. She whispered softly in my ear, "Fuck your goddess."

I had been keeping my hands lightly on Kaitlyn's ass, but now I firmly grabbed her and bounced her up and down on my cock. I was fucking Kaitlyn! Every time I thrust into her, she moaned huskily. When she had told me at the lake house that she wanted to fuck me, it had freaked me out. It had been too much too fast for me to handle. And then the opportunity seemed to have passed by when she had sent Paul home. But I hadn't forgotten what she had said. I had thought about it regularly at work and when she was wearing a bikini at the pool. I didn't think I'd fuck her - I had no intention of making a move on her and would have rejected any move she made on me - but I grew to accept that it was something I wanted and would enjoy. And now, thanks to Joanna, I was doing it.

Kaitlyn leaned forward, brought her hands down to outside my shoulders and supported her upper body as I fucked her at a different angle. I was sliding my cock in and out of her slick, grasping pussy, and it was heaven. I loved listening to Kaitlyn loudly moan as she impaled herself. As we fucked, her perfect tits danced up and down wildly. I couldn't take my eyes off of them.

Kaitlyn noticed me staring at her tits. "You like?"

"I love. Sit up straight for a moment."

Kaitlyn sat straight up in her goddess pose and held that position. She was so fucking beautiful. I reached up and took her tits in my hands, squeezing them lightly. They were still a wonder to me, and I still had difficulty believing that I was holding them.

Kaitlyn suddenly leaned forward, resuming her position just above my body. My hands automatically resumed their position gripping her ass, and I was sliding her up and down on my cock again. She said, "Joanna said for you to give me what I wanted most in the world. And that was for you to fuck me."

I smiled. "Aye aye, Captain."

After a few more thrusts, Kaitlyn said, "Dear God, it feels so good. I've wanted this for so long, and it's as good as I'd hoped it'd be."

Girl-on-top was not my favorite position. I could tell I was getting close to cumming, and I didn't like cumming in that position. "Mind if we switch positions?"

"Not at all."

Kaitlyn got off of me.

"Doggie-style?" I suggested.

"Sounds great."

Kaitlyn dropped to her hands and knees. I moved behind her. "I want to be looking at your gorgeous ass when I cum in you."

"You think I have a gorgeous ass?" Kaitlyn said as she looked back at me.

I slid my cock into Kaitlyn. "I think all of your body is gorgeous."

Kaitlyn looked forward again. "Fuck me, Brandon. Fuck me like I've always wanted you to."

I grabbed Kaitlyn by the waist and started fucking her. She slammed her ass back to meet each of my thrusts. Our speed picked up and soon I was pounding Kaitlyn as hard as I could. I didn't know if it was the position or what, but Kaitlyn talked to me now instead of just moaning.

"God yes! God yes! It feels so good. Fuck me, Brandon. Fuck your sister. Give it to me. Give it to me hard. Uh! Uh! Uh! Like that! Fuck me like that!"

I fucked Kaitlyn with everything I had. She was an incredible woman and an incredible sex partner. It felt so great to be fucking her, to hold her firm ass as I thrust into her over and over. My heart was pounding with exertion and excitement.

"Oh, God! Oh, God! I love it! I love it!"

I loved it too. The pleasure was so intense that I knew I wasn't going to last much longer. I continued fucking Kaitlyn hard, savoring every thrust. Kaitlyn stopped talking and was now only making low grunts. We were both soaked with sweat. I could feel myself getting closer and closer to the edge. Finally, I went over. I felt an explosion of pleasure, and I was cumming in Kaitlyn. I felt so good to squirt load after load into her. I slowed steadily as each spurt got smaller until I finally stopped. I collapsed, leaning gently on Kaitlyn's back while keeping my cock inside of her.

"That was incredible," I panted out.

"I loved it. I loved every second of it."

"I love you, Kaitlyn."

"I love you too, Brandon."

I stood up, pulled out of Kaitlyn, and flopped down on my back on her bed. "Tired. That was a hard fuck."

Kaitlyn stretched her legs out and stayed on her stomach. She raised herself up and gave me a kiss. "Thanks. For giving me what I wanted most."

"I wanted it too."

"I'm glad. But I've wanted it for years. Have you?"

"No." I shook my head. "Only since last week."

"I'm glad you wanted me. And I'm immensely grateful to Joanna for letting us have this time together." Kaitlyn pulled back and rolled onto her side. "And speaking of your girlfriend, you should go to her. I don't want you to overstay."

"Okay."

I gave Kaitlyn another kiss on the lips, climbed off the bed and staggered off. In the living room, I noticed that mine and Joanna's clothes were gone. I opened the door to our bedroom and walked in. Joanna was reading her tablet on our bed naked. "Did you have fun?" she asked.

"Yes."

"Good. Now fuck me like you fucked your sister."

* * * * Chapter 5 * * * *

The next morning, I woke up lying on my back. Joanna in the night had rolled off my shoulder like she had been doing and was asleep on her side next to me. I gently reached out and guided her to put her head back on my shoulder. "I love you," I said.

"I love you too." Joanna kissed me on the cheek before snuggling into me.

"Are you okay with last night?" I asked gingerly.

"Yes. It was my choice. The bigger question is are you okay with last night?"

"I think so." My thoughts swirled, but not nearly as much as at the lake house. "Kaitlyn and I are adults. We did what we wanted to do. Everything was consensual. Hopefully, it won't ruin our relationship or damage my relationship with you."

"I don't think it'll damage our relationship. Quite the opposite. Do you love me more for letting you have last night?"

I squeezed Joanna. "I do. I think I do."

"I don't think you have a fixed amount of love, and that if you love Kaitlyn more, then you'll love me less. You can love me more while loving Kaitlyn more. So, I'm hoping last night will strengthen all our relationships. But we'll have to wait and see on that."

"Yeah. We'll have to wait and see." I laid there in a kind of awe over last night. That Joanna would let me and encourage me to have sex with another woman. That sex would be so great with Kaitlyn. I knew it was wrong in many ways, and yet it had felt so right. And all those thoughts kept circling back to one question that I eventually asked Joanna. "Will you let Kaitlyn and me do that again?"

"Maybe. I'll have to see how it goes." Joanna moved off of my shoulder and moved back a bit, so she was lying on her side facing me. "I really enjoyed the nights at the lake house. The sex on those nights was extra special. I'm thinking about doing something similar this summer, but only once every week or two. What do you think of that?"

"Sounds awesome." How could I not like it?

Joanna moved back to put her head on my shoulder. "I'll talk to Kaitlyn about it. I want to see how things go between the three of us for a while before committing to anything."

"Okay."

"Now, I want to sleep some more."

I kissed Joanna on the forehead. "I love you." I ran my fingers through her hair until she dropped off to sleep, and then I went back to sleep too.

* * * *

Joanna took first shower, so she was talking with Kaitlyn when I came out for breakfast. I made a couple of toaster strudels before sitting down at the dining table with them. It was like everything had changed and yet nothing had changed. We didn't mention last night. Instead, we talked like we normally talked, and then I rushed off for work. As I worked, I wondered what Joanna and Kaitlyn were talking about. And I remembered making love to Kaitlyn last night. It had been special. It had been very, very special. At the same time, it didn't keep me from wanting to make love to Joanna. The more I thought about it, the more I liked Joanna's idea of having a night like at the lake house occasionally. Not often enough to disrupt Joanna's and my relationship, but often enough that I wouldn't feel tempted to do something with Kaitlyn without Joanna's approval.

Tuesday night, I was on the couch playing a game on my phone. Kaitlyn came out and said to Joanna, "Got the shopping list ready?"

"Here it is."

Kaitlyn said to me, "Let's go shopping."

When I started driving, I said, "You were right at the lake house when you said Joanna and I should live together this summer. It's worked out great. Joanna has been super easy to live with. We've had a few problems, but they haven't been big. It's good dealing with those initial problems now while the stress is low and not at college when Joanna and I both have papers due. I hope you're not angry that I rejected your suggestion."

"No, I'm not angry at all. Do you mind if I talk about my feelings for you? That I love you and am sexually attracted to you?"

I thought for a moment. I was slightly uncomfortable with the idea of talking about our feelings and our being sexually attracted to each other but decided it was stupid to not discuss them. "I don't mind. Joanna knows we love each other and are sexually attracted to each other. I don't see why we can't discuss it."

"Okay, so I wasn't angry that you argued with me. In fact, it got me quite hot. I loved that you weren't letting me have my way, that you weren't letting me manipulate you into accepting something you didn't want. I always want you to push back when you disagree with me. Your willingness to do so is one of the reasons I'm so attracted to you."

"I'll keep that in mind." I laughed. "This is all so crazy. Here I am talking with my sister about how we love each other and what attracts me to you, and I know my girlfriend is okay with it. Is this really fine? Is this going to blow up some day?"

"Well..."

"Let me ask you about something else before you answer that. Were you surprised by what happened Saturday?"

"Yes and no. Did I have any idea Joanna would do that? No. But her giving me what she knew I wanted didn't surprise me. That's the way we are - we do things for each other."

"Did anything she said surprise you?"

"Yes. I had no idea she had used you to become my best friend. But that doesn't matter to me as she's my best friend for a mountain of reasons. I'm glad she's accepting of you and me, regardless of how she started down that path. And it surprised me that she had encouraged you and me at the lake house as a way of deepening your relationship."

"I was surprised by those things, but the biggest surprise to me was that she was so okay with us loving each other, and in fact that she saw that as a good thing. The next morning, she told me she didn't think I had a fixed amount of love, so that loving you more didn't mean I would love her less."

"That's my hope too. Have you heard of the TV show, 'Seeking Sister Wife'?"

"No."

"I came across it when I was looking for ideas of how the three of us could get along living together. I watched some clips, and I felt so sad for the women. For the two families I watched clips of, it was like the guy went out one day and happened to pick up a second wife. If one of my boyfriends had picked up a second girlfriend while he was out, I would have dumped him as soon as he introduced her. And the two wives had the same roles, being the stay-at-home mom. Once the second wife moved in, the first wife was redundant. There didn't seem to be anything in it for the first wife about having a second wife. It was all about the guy wanting another woman to fuck."
"Okay." It sounded like a show that wouldn't appeal to me.

"It really affected me. I was like, 'Joanna and I aren't going to be like this.' So I've tried hard to be complementary to Joanna and not redundant. Joanna has her role, I have my role, and there's little overlap. If Joanna and I were both to cook, then there would be competition about which of us cooked better. And there'd be arguments about how to organize the kitchen. So I've let Joanna own the kitchen, and I've encouraged you to help her cook so that cooking will be your time together. I go do other things while she's cooking. Making the beds and doing grocery shopping are the things we do together. And they're also things that Joanna doesn't want to do. So my presence in the household makes Joanna's life better, and Joanna's presence in the household makes my life better. So you can love Joanna for who she is and what she does, and you can love me for who I am and what I do, and not feel conflicted because Joanna and I have different roles and don't compete."

I hadn't noticed that Joanna and Kaitlyn had different roles, but now that Kaitlyn pointed it out, I knew it was true. "And part of Joanna's role is to be my girlfriend."

"True. One of the things I realized at the lake house is that I can't be your girlfriend. And as she's your girlfriend, you are to be faithful to her. She gets to decide if she wants to share you with me. And I need to build her trust in me that I'll never do anything with you she hasn't given her approval to."

I turned that over. "I'm really happy, and it's easiest to give Joanna all the credit as she is my girlfriend. I'm having good time after good time with her. Every day, I feel more and more compatible with her. I feel I'm falling more and more in love with her. But you're there too. I'm having good time after good time with you. Every day, I feel more and more compatible with you. I also have that feeling of falling more and more in love with you. But because you're not my girlfriend, it's easy to not think about that."

"I'm glad to hear that you feel like you're falling more and more in love with me as I feel like I'm falling more and more in love with you."

"Where is this going?"

"We'll see." I had the feeling Kaitlyn knew where she wanted it to go but didn't want to say.

"Are you going to live with me and Joanna in the fall?"

"I think it's too early to decide."

There was something to waiting, but I felt like Kaitlyn had already decided and was just being cagey.

* * * *

Over the next week, I realized that there was quite a bit of sexual tension between Kaitlyn and me. Joanna had to have seen it. Having sex with Kaitlyn had discharged it for a while, but by Saturday I could feel it building again. Nothing too overt; just an occasional subtle sign from Kaitlyn that she wanted me, and I'm sure I made the occasional subtle sign that I wanted her. But otherwise, the week didn't feel any different than the week before. I still loved Joanna and did my best to show it every day. I still enjoyed spending time with Kaitlyn, sometimes alone like when we made the beds together, but most commonly while we were with Joanna. If anything, I got along with both of them better.

Sunday night as Joanna and I were cuddling after sex, she said, "Tomorrow, Kaitlyn and I will start planning something special for next weekend. Some fun to discuss as we drive to work."

"I'll look forward to next weekend."

As the week progressed, Joanna and Kaitlyn got increasingly giggly. Kaitlyn had taken Mom's sewing machine, and Friday evening I heard sewing sounds behind the closed door to Kaitlyn's bedroom. Saturday morning, Joanna finally gave me a clue. "We're going out to a Polynesian restaurant tonight."

"Okay." A surprising thing about Joanna was that she liked to try ethnic restaurants she had never eaten in before. "What do they serve at a Polynesian restaurant?"

Kaitlyn said, "Polynesian food, Silly." Both girls laughed uproariously.

Joanna said, "And don't look it up. Let it be a surprise."

"Tonight is going to be lots of surprises," added Kaitlyn. "We're counting on you being a good sport and going along with them as they happen."

"I'll be a good sport." It was easy to be a good sport when I knew that playing along would result in a night of hot making out and even hotter sex. "Off to work."

"Call when you leave work," said Joanna. "And when you get here, go straight to our bathroom and take a shower. The clothes you are going to wear will be laid out on the bed."

When my workday was over, I did just as I was instructed. I didn't see Joanna or Kaitlyn as I crossed from the apartment door to my bedroom. I stopped and looked at the clothes. It was a normal pair of jean shorts and a bright green shirt that I hadn't seen before. The material was cotton and had a wild print of flowers of different sizes. It was so bright; I'd be like a walking neon sign.

I showered and put my clothes on. My hands trembled as I buttoned up my shirt. I was very excited for tonight and wondered what the girls had planned.

When I stepped out of the bedroom, Kaitlyn and Joanna were doing something at the dining table. They were both wearing blouses made from the same print as mine but in different colors. Kaitlyn's was a bright blue, and Joanna's was a bright orange. I said, "I'm ready to go."

"Just a minute", said Kaitlyn. "Joanna is almost done."

Joanna did something and then lifted up a string that had several flowers on it. Kaitlyn took the string and lifted it over Joanna's head. I realized that the string was a loop with flowers on the bottom. As I got close, I could see that the blouses Kaitlyn and Joanna were open in the front, something like a vest. Below their blouses, each was wearing a white, knee-length skirt. As I got a closer look at the front of their blouses, I could see that each was wearing several strings of flowers in the open area in the front of their blouse. Neither was wearing a bra, so the flowers were the only coverage of the middle of their chests. With both of them, I could clearly see the side of their tits, about a quarter of each one.

Joanna and Kaitlyn turned to me and stood up straight to model their outfits. Kaitlyn's hair was braided with flowers occasionally worked in. "What do you think?" asked Joanna.

"You're beautiful. Both of you are beautiful. And sexy. Are you wearing anything under those blouses?"

Kaitlyn opened her blouse quickly, giving me a flash of her naked tit. "Nothing," she said with a big smile.

Joanna said, "You'll have to do almost everything for us tonight, so we can keep our blouses closed."

I didn't know how this would work, but it sounded like an intriguing night.

We got into Kaitlyn's car; she was driving, and Joanna and I got in the back seat. As soon as we were buckled in, Joanna took my hand and slipped it under her blouse. "You have to keep your hand below the flowers. Can't have you damaging them."

As I ran my hand over her bare stomach, I said, "You're so naughty."

Joanna laughed. "And you love your naughty girl?"

"I very much love my naughty girl."

We made out the whole drive to the Polynesian restaurant. When we stopped, Joanna unbuckled her seat belt and then opened her blouse wide open to show me her whole chest. She quickly closed it and laughed. I got out of the car and went around to her door. When I opened it, she flashed me again before getting out. Kaitlyn was still sitting in the driver's seat. When I opened her door, she flashed me too before getting out.

I adjusted my hard cock as we walked away from the car. There wasn't anyone outside the restaurant. When I opened the doors, there were several groups waiting to be seated. I could see the eyes of several guys go wide when they got a look at Joanna and Kaitlyn. Kaitlyn went over to the hostess and told her that we had reservations. We were quickly seated. Normally at restaurants, Joanna sat to my right and Kaitlyn to my left, and I'd hold Joanna's hand on the table to make it clear that she was my girlfriend. This time, Kaitlyn sat across from me, and Joanna didn't hold my hand as she was keeping her blouse closed. We had Pot Stickers as an appetizer, and then the girls split a Maui Pineapple Chicken while I had a Kalua Pork. I sampled the girls' plate, and they sampled mine. The food was good. Not a restaurant I would have chosen, but it was good while being different. The girls were on their best behavior inside the restaurant, with no flashing and a concerted effort to keep their blouses from getting too open. Still, it was quite distracting to look across at Kaitlyn and see so much bare tit, and the angle I had with Joanna meant I could frequently get dark glimpses of her whole right tit. I was hard the whole meal.

When we were outside after the meal, I said, "Every guy had their eyes on you two the whole time we were in there."

Joanna and Kaitlyn laughed. I took Joanna's hand as we walked toward the car. The parking lot was dark with no one in sight, so I wasn't worried about accidental exposures now. Joanna and Kaitlyn talked about the many times guys had eating failures as they stared at them and also the many dirty looks women gave their men. They had very much enjoyed themselves.

"You two are so naughty," I said as we approached the car.

"We're about to get naughtier," said Joanna as she took the keys from Kaitlyn. I opened the driver's door for her, and she gave me a big flash once she sat down. I opened the door behind her for Kaitlyn, and she too gave me a big flash once she sat down. I went around to the other side and got in with Kaitlyn. Once I had my seatbelt on, I turned toward Kaitlyn. She took my hand and slipped it under her blouse. She said, "You don't have to worry about damaging the flowers now," as she bent forward to kiss me.

* * * *

I held open the door to our apartment, and the girls slipped in. I followed after them and closed the door. They smiled at each other as they moved over to halfway between the couch and the dining table. When I joined them, Joanna positioned me between her and Kaitlyn with me facing her. "You are overdressed," she said. She began unbuttoning my shirt. "Don't use your hands until we tell you to. Just stand there."

Once Joanna had my shirt unbuttoned, she opened it. I felt Kaitlyn take it off my shoulders and pull it off me. Joanna said, "The big spin begins." She moved to my left and Kaitlyn moved in front of me from my right.

Kaitlyn dropped to her knees in front of me. "Have you had a good time so far?" she asked sultrily while undoing my shorts.

"I've had a great time so far."

I could feel both Joanna and Kaitlyn grab my shorts and pull them down.

"Good," said Kaitlyn. "Joanna and I will try to keep that up." As Kaitlyn stood up, she slid her hand up my hard cock. "And you keep this up too." When she was fully standing, she said seductively, "Kiss me. And remember, no hands."

I leaned forward and kissed Kaitlyn while keeping my hands at my side. I so wanted to cup her tits again like I had in the car, but I knew to follow the rules. The girls were apparently going to do their best to drive me crazy before we had sex.

As I kissed Kaitlyn, I felt Joanna rub her butt against mine. She rubbed it side-to-side a few times, and then she circled her butt around mine twice. God, that was hot. It was amazing to feel one pressed against me sexually while the other kissed me. When Joanna removed her butt from mine, Kaitlyn stopped kissing me. She moved around me as Joanna moved in front of me. I could see that Joanna had taken off her skirt and was now wearing only white cotton panties below her blouse. She had spread the blouse further open so I could now see about half of each tit. Joanna put her hands on the side of my chest and asked, "Do you love your naughty girl?"

I smiled at her. "I love my naughty girl very much."

Joanna kissed me, and then rubbed her hands over my chest as we continued to kiss. I felt Kaitlyn press her butt against mine. As Joanna had done, Kaitlyn rubbed her butt side-to-side and then in a circle. When Kaitlyn moved her butt away from mine, the girls switched positions. Kaitlyn too had removed her skirt and was now wearing only white cotton panties below her blouse. She too had spread the blouse further open. She too put her hands on the side of my chest. "Do you love me, Brandon?"

"I love you very much." It was the first time that I had told Kaitlyn I loved her in front of Joanna. It was a little uncomfortable, but Joanna knew that I loved Kaitlyn. Then I realized that Joanna had set it up so I'd tell Kaitlyn 'I love you' in front of her.

Kaitlyn smiled and kissed me. As we kissed, I felt Joanna's bare tits press against my back. Joanna kissed my back and rubbed her hands across it while dragging her tits slowly all over it. I was in sensory overload. When Joanna lifted her tits from my back, Kaitlyn ended the kisses and moved behind me. When Joanna moved in front of me, I could see the flower strings were gone. The blouse was now wide open and the top of it was partially down her shoulders. There was no sign that Joanna was angry with me for saying I loved Kaitlyn. In fact, she looked extremely happy.

"You're so beautiful," I said.

Joanna smiled, took my hands and lifted them to her tits as she kissed me. As we kissed, I felt Kaitlyn press her bare tits against my back. It was such a weird feeling, to be holding one set of tits while feeling another pressed into me. But it was also an absolutely wonderful feeling. When Kaitlyn took her tits off of me, the girls changed positions again. Kaitlyn also had removed the flower strings and had her blouse as Joanna had had.

"You're so beautiful," I told her. I was such a lucky guy to have two beautiful, wonderful women in love with me and okay with me having sex with the other.

As I kissed Kaitlyn, I felt Joanna press her back against me. It was kind of an odd feeling, her sliding her back all over mine. I cupped Kaitlyn's tits and played with her nipples as Joanna moved her back up and down mine. Again, sensory overload. At the same time, I was thinking we were getting close to the end of this phase. What would happen next?

When Joanna moved her back off mine, Kaitlyn moved to the back as Joanna moved in front of me. As I expected, she was wearing only her panties now. "Like what you see?" she asked.

"Very much so."

"You are to use your hands now below my tits."

I dropped my hands to Joanna's waist and held her firmly. "This has been so special and memorable for me. I hope it's been that way for you."

"It has! I'm really happy with how it has turned out."

Joanna kissed me. I dropped my hands down and squeezed her ass as we kissed. Kaitlyn began pressing her back against mine. I slipped my hands into Joanna's panties to squeeze her ass directly. She kissed me more vigorously. As I kissed and groped, I couldn't help wondering what the next thing would be. I couldn't think of what Joanna could press into me from behind.

Kaitlyn pulled her back off of me and the girls changed positions again. Kaitlyn too was only in her panties. She too asked me, "Like what you see?"

"Very much so."

I dropped my hands down and squeezed Kaitlyn's ass as we kissed. I felt Joanna lightly pushing me toward Kaitlyn's bedroom. Kaitlyn and I slowly walked that way while kissing. Once we were in Kaitlyn's bedroom, Joanna said, "See you in a while, Brandon," and closed the door.

Kaitlyn grabbed my hand and pulled me over to the bed. "If you're anything like me, you're ready to cum." She sat down on the bed and pulled down my boxers. Once my boxers were off me, she grabbed my cock and guided it to her mouth. The warmth and wetness of her mouth felt wonderful. She slid her lips down my cock and then back up again, sending waves of pleasure through my body. She bobbed a few more times, and it was too much.

"I'm cumming," I warned her.

Kaitlyn kept bobbing until I was shooting jet after jet of hot spunk down her throat. Kaitlyn never slowed, and quickly sucked down my full load. Once I was drained, Kaitlyn released my cock and scooted back onto the bed. I noticed that the covers were pulled down and a towel was on the bed. Kaitlyn quickly yanked off her panties and said, "Now my turn." I moved to give her oral sex, but she grabbed my hand and brought it to her pussy. "Like that."

I slipped my fingers inside her pussy lips and found her soaking wet. Kaitlyn grabbed my chest and yanked me next to her. She kissed me frantically as I worked her clit, and then she threw herself back on the bed. "Yes! Oh, God! Yes! Oh! Oh!" I worked her clit hard and fast. "Oh, God! Oh, God!" Kaitlyn arched her back. "YEEESSS!"

I worked her clit for a little bit more before letting her finish cumming. Once she resumed breathing normally, Kaitlyn said, "Fuck me, Brandon. Fuck me good and hard. I want you so bad."

I moved between Kaitlyn's legs. She grabbed my cock and guided it inside of her. I slid in part way, pulled back and then slid all the way in as Kaitlyn raised her crotch to meet mine. Kaitlin rotated her hips and raised her legs, so her feet were up in the air. I was fucking her almost straight down. Slam! Slam! Slam! Slam! Slam! Each time I fucked her, I'd press Kaitlyn into the bed, and each time, I'd pulled back, she'd almost bounce off the bed. I had never fucked a girl from this angle before. And both Kaitlyn and I were fucking frantically. My heart was pounding with the exertion of fucking her so hard.

To take a quick break, I bent forward and kissed my sister. Kaitlyn grabbed a hold of my lower lip and held it as I slowly pulled back from her. She released it just as it was about to pull out of her mouth.

"I love you so much, Brandon."

"I love you too, Kaitlyn."

"You feel so good inside of me. I've wanted to fuck you for so long, and it feels so right now that we're doing it."

I went back to fucking Kaitlyn. I moved my arms inside her legs so she could rest her legs on them. Another angle that I had never fucked in before. I was looking down now into my sister's beautiful face as I fucked. She had a look of pure bliss as I pounded her. Looking lower, I could see her big tits bouncing around. God, she had great tits. But now wasn't the time for admiring them. Now was the time for fucking.

It did feel good being inside my sister. I knew it was wrong, but it felt so right. She loved me, I loved her, and we were expressing our love the way God intended. With this angle, Kaitlyn didn't bounce off the bed as much, but the bed sure did shake and squeak. Every stroke filled me with pleasure. Every stroke made Kaitlyn moan loudly.

"This can't be wrong," said Kaitlyn.

"This isn't wrong."

"I'm yours, Brandon. Take me."

Kaitlyn lifted her legs higher and again I was fucking her straight down. I loved the feeling of bouncing her off the bed. I felt so damn powerful. I slammed Kaitlyn over and over, and then I felt my balls tingle. I was going to cum in my sister again. She was mine, and I was going to fill her pussy to show that she was.

I started cumming. I pushed forward one more time, pinning Kaitlyn to the bed as I shot into her again and again. I was breathing hard as I finished pumping Kaitlyn full of my cum. We held that position with Kaitlyn's legs in the air as we caught our breath, and then Kaitlyn slowly lowered her legs.

"That was incredible," I said.

"It was. God, I wanted that."

I kissed Kaitlyn. "You're an amazing fuck."

"Thanks. And you're pretty awesome yourself."

I pulled out and collapsed on the bed next to Kaitlyn. I was still trying to catch my breath. Once I did, I asked, "Can we talk for a bit?"

"Sure. That was so quick, I don't think Joanna would mind if we talked for a while."

Kaitlyn and I rolled on to our sides, so we were facing each other. I said, "I love you."
Kaitlyn kissed me. "I love you too."

"How will this work long-term?" I asked Kaitlyn this once already, she had dodged answering it, but I always kept coming back to it.

"Long-term, you and Joanna will be very happy together. You've been great for her, and I think she's been really good for you. You two have gotten along far, far better than I had dreamed when I first suggested you date her. I love the idea of you two marrying someday."

"Okay. But it's way too early to talk about marriage."

"I know you're not into thinking about the future much. Joanna is, and I'm even more than Joanna is. We've talked about you two getting married, buying a house, how long she wants to teach before you start a family, and her being a stay-at-home mom once you have kids." Joanna was going to be an elementary school teacher. "I'm not trying to press you into committing to anything, I'm just trying to give you an idea of how committed I am to you and Joanna being a happy couple long-term and also to let you know the kind of conversations Joanna and I have. Anyway, I've been enjoying living with you and Joanna. I'll like to do things with either of you and with both of you. And I like working with Joanna to strengthen her relationship with you."

I furrowed my brow. "You haven't had to do anything because Joanna and I have gotten along great."

Kaitlyn rolled her eyes. "You're such an idiot at times," she said patronizingly. "The first week we moved in, Joanna prepared a calendar for the week and posted it on the refrigerator. She knew she wouldn't be good at asking you to do things around the apartment, so her plan was she'd post weekly a calendar of when you were to do what chore, and you'd follow that. But you ignored the calendar and didn't do the first chore you had agreed to do when she had scheduled you to do it."

"What was the chore?"

"Clean your bathroom. She asked you to do it, you said you'd do it in a little bit after you got to a good stopping point in your game, and then you didn't do it. Joanna ended up cleaning the bathroom herself. She was really upset about it. She felt like you had broken your promise to do the chores you had agreed to in the first week of living with her."

I thought back to that day. It had happened like Kaitlyn said. I had thanked Joanna for cleaning the bathroom and hadn't thought any more about it. I hadn't noticed that Joanna was upset about anything.

"Since then, my job is to make sure you pay attention to the calendar and that you do the chores you've agreed to do in a way that's acceptable to Joanna." When it was time to clean the bathrooms, Kaitlyn has told me 'Time to clean the bathroom' and then has checked on how good of a job I've done after she was done cleaning her bathroom.

"Okay. I screwed that up. But I wasn't asking about what will happen with Joanna and me long-term. I was asking about what will happen with you and me long-term."

"You know what I've liked most about this summer?"

"No idea."

"I told you that at the lake house, I became obsessed with the idea of you being my boyfriend. It was a stupid idea for many reasons, one of which was that we'd have to commit to being boyfriend-girlfriend without any idea if it'd work. Even though we've gotten along great as siblings, we might have been awful as a romantic couple. What I've liked most about this summer is that I feel like it's been a dry run of us being boyfriend-girlfriend. There isn't much difference between how you treat Joanna and me until bedtime. And the two times Joanna has let us be together, you've treated me very much like a girlfriend. And I've really enjoyed that. We love each other, we've told each other that we love each other, and we're comfortable now with that we love each other and that we're sexually attracted to each other. I feel that if you had become my boyfriend, we would be a very happy couple now."

"But I didn't become your boyfriend. Joanna remained my girlfriend, and she still is."

Kaitlyn reached out and stroked my chest. "And she's what's important now. I know that isn't much of an answer, but it's the only one I have."

* * * *

By this time, we had made friends with some people in the apartment complex. Tuesday, we had a couple a few years older than us over for dinner. We had a good time. They had been living together for almost a year. When we told them about how we divided our household chores, she made some snipes about him not doing enough around the apartment. I felt like Joanna and I got along much better than they did. And Kaitlyn and I got along much better than they did. The whole time they were over, I kept telling myself, Don't act like you're in love with Kaitlyn. It was kind of eye-opening to me just how much I treated Kaitlyn like a girlfriend instead of like my sister.

Friday, we went to a party at an apartment in our complex. We knew some of the people and met quite a few we didn't know. Whenever I looked over at Kaitlyn, at least two guys were in the group she was in. The guys changed regularly through the evening. It was a struggle all evening to not go over to wherever Kaitlyn was and try to drive off the guys she was talking to.

Over the week, I continued to have the feeling that I was falling more and more in love with both Joanna and Kaitlyn. I thought several times about Kaitlyn saying that I treated her like a girlfriend. I saw that now. And I saw that Joanna was fine with it. She didn't expect me to treat her differently than Kaitlyn. We were three equals, contributing equally and making decisions jointly. All three of us were comfortable living together.

The whole week, I kept wondering how this will work long-term. One night while Joanna and I were making dinner, I asked her, "Have you asked Kaitlyn whether she wants to live with us in the fall?"

"A couple of times," Joanna said as she continued to cook.

"What did she say?"

"It's too early to decide."

"What do you think of that?"

"I agree."

It upset me somewhat that she seemed to be taking this so lightly. "Why do you agree?"

Joanna stopped cooking and looked sharply at me. "It's a hard decision, okay? And a big one. Give it time."

Joanna went back to cooking. The way she had said that, it was like she had to make the hard decision, not Kaitlyn.

* * * *

Saturday night after dinner, Joanna said, "Wait on the couch," and then she and Kaitlyn went into Kaitlyn's bedroom. I sat on the couch wondering what would happen tonight. Why the couch tonight? How would they alternate while I was on the couch?

Joanna and Kaitlyn came out of the bedroom wearing short black skirts and fitted white dress shirts. The shirts were tied off below their tits, exposing their midriffs. They looked like two dancers from Britney Spears' "Baby One More Time" video. In fact, Joanna started some music on her phone and "Baby One More Time" came through the speakers of our stereo. Joanna moved in front of me and danced sexily while singing to the song. She stood over me and shook her chest, and it was obvious she wasn't wearing a bra. She danced like that until she sang "Hit me baby one more time," and then she jumped out of the way and Kaitlyn moved in front of me.

Kaitlyn danced sexily in front of me, and she too obviously wasn't wearing a bra. She danced until the chorus, when she switched with Joanna. The girls alternated dancing sexily in front of me. Eventually, Joanna pulled up her skirt to reveal thong panties. Kaitlyn upped things even more by straddling me and shimmying her chest right in front of me. When Kaitlyn climbed off me, Joanna climbed on me. She rubbed her crotch against mine. Kaitlyn said, "Keep your hands by your side." The girls kept taking turns. After a while, they had me stand up, stripped me naked and had me sit back down on the couch again. Both girls took off their panties and "danced" with their bare pussy pressed against my cock. When Joanna was on top of me, she untied her shirt to reveal her tits. She shook those to the music as she rocked her pussy on my cock. Kaitlyn disappeared for a little bit before returning with a beach towel which she spread out on the couch next to me. I guessed I'd fuck Kaitlyn on the couch tonight before joining Joanna in our bedroom. Joanna hopped off me and Kaitlyn climbed on. She untied her shirt and rubbed her tits against me as she swayed to the music. I saw behind her Joanna take off her shirt. When Kaitlyn hopped off, Joanna had me move over to the center of the towel. To my surprise, Kaitlyn walked off.

Joanna straddled me. "Use your hands now," she said. I slipped my hands under her skirt and gripped her ass in my hands. Her pussy was pressed against my cock. I helped her slide her pussy up and down my cock a few times. "Are you ready to fuck your naughty girl?" she asked. She didn't wait for an answer and instead impaled herself on my cock. We fucked like that for a while, and then I pulled her off me and flipped her, so she was lying over the armrest of the couch. I fucked her doggie-style there.

"This reminds me of the lake house," I said. "That was such a great fuck. It was my favorite fuck of the whole week."

Joanna was meeting my every thrust. "Yeah, that was so naughty. I love being naughty."

A few more thrusts, and I was cumming into Joanna. When I finally pulled out, Joanna said, "Wipe yourself and then go to Kaitlyn. You're sleeping with her tonight."

"I am?" It was somewhat obvious that that was the plan, but I was surprised that Joanna would agree to me spending the night with my sister. It had seemed very important to Joanna that I sleep with her after having had sex with Kaitlyn.

"Yes. Kaitlyn asked nicely if you could sleep with her, so I said yes." Joanna kissed me. "Now go make her happy."

* * * *

Monday after dinner, Kaitlyn said, "I need to have a serious talk with Joanna. Would you mind going to the pool for a while?"

This sounded ominous to me. I looked at Joanna and she said, "Go. I think I know what Kaitlyn wants to discuss."

I hung out at the pool until I got a text from Joanna asking me to come back. When I did, Joanna and Kaitlyn were sitting at the dining table. Both looked serious, but neither looked angry. I sat down at the table.

Kaitlyn turned to Joanna. "How do you want to handle this?"

"You had a good sales pitch for your proposal. Give it to Brandon."

Kaitlyn turned to me. "You and Joanna have asked whether I want to live with the two of you this fall. I've loved living with both of you. I love you both so much." She gestured toward Joanna. "I greatly appreciate Joanna sharing you with me." Kaitlyn brought her hands back in front of her. "But I don't want it to be like this in the fall. I don't want it to be only once a week with you. I don't want to be the girl on the side. If I'm going to live with you two this fall, I want it to be with Joanna and me sharing you equally, and you being equally committed to us."

"Kaitlyn..."

"Let her finish," said Joanna.

Kaitlyn looked at Joanna gratefully. "I want to be able to build my life around you as much as Joanna does." Kaitlyn raised her hand and faced me. "I know this sounds crazy to you. Let me say first that my dreams are the same as Joanna's dreams. I want you two to get married. I want the three of us to buy a house around the time that Joanna wants to buy a house. I want you and Joanna to start a family around the time that she wants to start a family."

I decided to double-check that. "Are those your dreams, Joanna?"

"Yes."

Kaitlyn continued. "But not only are our dreams the same, they depend on both of us contributing to making them happen. You and Joanna won't make enough to buy the kind of house Joanna wants when she wants it. But the three of us can. When you and Joanna start a family, you'll struggle to live on just your salary. But it wouldn't be bad if our family was living off of your and my salaries. I haven't talked to you about my dreams, but I'm very ambitious about my career. But I don't want the loneliness of the single, ambitious young professional life. I want to be able to come home after a long day and talk to you and Joanna about it. I want home-cooked meals, even if I work late. I don't have to worry that this is my night to cook dinner when my boss suddenly drops a big project on me. I want to be able to take long business trips and not have my guy get frustrated about sleeping alone. I may not have kids, or I'll at least wait until my forties as having children sets a woman's career back so much, but I want to be involved in raising children earlier than that. I'd be thrilled to help raise a little niece and nephew, but not have the main responsibility for raising them. So I'm proposing that you and Joanna make me an equal to Joanna. In return, I'll give you two my full financial support, which will enable you and Joanna to live the life you want to live." Kaitlyn looked at Joanna. "Did I cover everything?"

"You didn't say how this would work."

"True." Kaitlyn turned back to me. "This summer would continue as it has been, with us having fun together on Friday or Saturday night, and you then sleeping with me. Once we move into our new apartment at college, we'll start sharing you equally. You'll spend two nights with me and then two nights with Joanna. Breakfast would mark the transition from one of us being your girl to the other. When it's my turn, you treat me like you treat Joanna. You can still hug, kiss and say 'I love you' to Joanna, but only short displays of affection. And when it's Joanna's turn, vice versa. Whenever we go out, regardless of who you're sleeping with, Joanna is your girlfriend, and we're very public about it. Let's say we're going out to dinner and a movie on my night. You and I would pick the restaurant and the movie. When we walk out the door, you're with Joanna until we walk back in the door, and then you're with me. We'll have some practice runs this summer to work out the details. I don't want to rush into the sharing, and I want all of us to work out as many of the kinks as possible before we start. At the same time, starting to share when our schedules all change because of school makes a lot of sense to me." Kaitlyn looked again at Joanna. "Anything else?"

"I think that's it."

I asked, "What if Joanna and I don't agree to your proposal?"

"I don't know. Maybe we'll continue on as we have, and I'll bring it up again later? Maybe I'll share an apartment with you in the fall, but I'd look for a boyfriend? Maybe I'll plan to live on my own in the fall? Depends on how you react to the proposal." Kaitlyn reached out and took my hand. "Remember the last time you asked me how you and I were going to work long-term? You knew then that what we're doing now won't continue to work. The only thing I think will work long-term is for Joanna and me to share you equally, and for you to be equally committed to each of us."

Joanna said to Kaitlyn, "I think it's best if you let Brandon and I discuss your proposal alone."

Kaitlyn released my hand and stood up. "Okay. I'll go for a walk around the apartment complex."

Joanna and I were quiet as we watched Kaitlyn leave the apartment. Once she was gone, I said, "Well, that was a bomb." I shook my head. "What did Kaitlyn say to you while I was at the pool?"

"Pretty much the same thing she just told you. She wanted to make sure I was open to what she was going to propose before she pitched it to you. She thought it was early to make the proposal, but she would like to lock up an apartment for the Fall soon. So we discussed if she should make her proposal now or wait a week or two."

"So you were okay with Kaitlyn suggesting you share me equally with her?"

"Let's go sit down on the couch."

Joanna and I got up and went over to the couch. When we sat down there, my arm automatically went over her shoulder. Joanna was quiet for a bit. "I love you, Brandon. You're the one I want to be with, and I want to be with you forever." I felt like this was a preamble for bad news. "There's something I need to tell you. I've been thinking about not telling you, but things won't make sense unless I tell you." I wondered what could be this bad. "When we were at the lake house, Kaitlyn talked me into dumping you for Paul so she could have you as her boyfriend."

"What?" I asked in shock. I took my arm from Joanna's shoulders.

"This was when I thought you were only dating me for the summer. I would date Paul through the summer and into the fall. At the time, I didn't feel like I was good enough to be your girlfriend long-term. I felt that Paul was more my level. And Kaitlyn had been my best friend for years, so I was far more loyal to her than to you. I had encouraged her for years to want you, so I couldn't deny her when she asked to swap boyfriends."

"But you didn't."

"We were supposed to swap during nap time on Thursday, but right after lunch she broke up with Paul instead. And I'm very glad she did."

"Hold it. How was this supposed to work? During nap time, you were going to tell me that you preferred Paul to me, so I should date Kaitlyn instead? When were you going to get Paul to agree to this?"

Joanna sighed. "Paul always went straight to the hammock when we went downstairs at nap time. Kaitlyn would keep you in the mud room. I'd go to Paul and tell him that Kaitlyn was breaking up with him. I'd suck his cock and tell him he was my boyfriend now. And then I'd return to the mud room. I'd tell you and Kaitlyn what I had done, and Kaitlyn would do to you what I described doing with Paul."

"So your cheating on me and then breaking up with me was supposed to put me in the mood to have Kaitlyn as my girlfriend? What if I didn't want to have anything to do with either of you after that?"

"It was a really bad plan. Kaitlyn was so crazy about you that she wasn't thinking straight. The rest of her plan was for you and I to continue to date in public as well as her and Paul, but secretly she and you would be a couple, and Paul and I would be a couple. And then at some point, I'd publicly break up with you and start dating Paul. I don't know what you and Kaitlyn were supposed to do publicly. But then it turns out that Kaitlyn knew I wouldn't like dating Paul because of his gaming addiction, so maybe I was supposed to break up with him privately and Kaitlyn would break up with him publicly? And I don't know how Kaitlyn was going to keep Paul from telling everyone that she and you were having sex. It was a really awful plan."

"It was." I stood up and crossed my arms. "I can't believe you'd agree to cheat on me and dump me for that loser."

"I knew you'd react this way if I ever told you about what I agreed to do. I'm only telling you this because I think you need to know for what I'm going to tell you next. Please sit down."

I stood there for a while and glared at Joanna. I couldn't believe she'd agree to betray me like that. But eventually, I sat back down on the couch, crossing my arms again.

"The reason I told you about Kaitlyn's plan for us to switch boyfriends was that I confronted her the Monday after we got back during our drive to work about not warning me that Paul was addicted to his game. She had built Paul up as the perfect guy for me, and I was pissed she had left out that detail. And she told me she would have taken care of me, and her plan was once I broke up with Paul, she'd share you equally with me. She added that she needed me to be your girlfriend to cover up the fact that she was involved with you. She'd go out to dinner and movies with you, but as a tag-along with you and me. I didn't think too much of it at the time. It was all kind of bizarre, and I felt like it was Kaitlyn trying to smooth things over with me. But after I shared you with her the first time, she started talking to me about my dreams, and I realized her plan was still to share you equally with me, but just how it came about would be different. She'd convince me that sharing you equally with her was the best way to achieve my dreams." Joanna wrung her hands. "I'm sorry I agreed to Kaitlyn's plan. I can't tell you how happy I am that she broke up with Paul instead of asking me to go through with it. I thought you'd be happier with Kaitlyn than me. Would you please forgive me?"
I let out a big breath. Joanna hadn't actually cheated on me. It had been Kaitlyn's plan, not hers. She thought by following Kaitlyn's plan, she'd make me happier. She had chosen to tell me this because she thought it was important for me to know. "Yes, I forgive you."

Joanna reached out, took my hand and pulled it between us. She looked at me with puppy dog eyes. I couldn't continue with my anger. I smiled at her and squeezed her hand.

"Back to Kaitlyn," Joanna said. "I think that's why she pushed so hard to have the three of us live together this summer. She saw it as her chance to convince both of us to include her fully into our relationship. And since we have started living together, she has tried to make herself integral to you and me happily living together. We've split the work up three ways, with me doing only what I want to do. She's taken on the role of reminding you to do the chores you've agreed to, knowing that's something I'd have a tough time doing. And her contributing to the apartment expense has made living together affordable for you and me."

"But she didn't convince you to share me equally with you, did she?"

Joanna raised her hands in a what-can-I-say gesture. "She did. She knows my weaknesses. She knows living in a house is hugely important to me. Living in an apartment is how I define being poor, and I don't want to live poor once I start working. I know how much I'll make as an elementary school teacher, I've run the numbers, and it'd take you having a great-paying job for us to be able to buy a house within a few years of my starting teaching. But it'd be easy for all three of us to buy a house a couple of years after I start teaching. I really want to be a stay-at-home mom like your mom, and again, it'd be very hard to do without Kaitlyn but relatively easy to do with her. I don't want to have to wait until I'm in my late thirties to buy a house and start a family. Children are very important to me. And most importantly, Kaitlyn has spent the time we've lived together showing she can make sharing you work at the once-a-week level, so I'm not fearful about going to equally sharing." Joanna took my hand again. "So what do you think about Kaitlyn's proposal?"

I had assumed Joanna would say no, so I'd say no. But Joanna was a yes, so was I a yes? "I don't know, Joanna. Finding out Kaitlyn talked you into cheating on me and dumping me for Paul doesn't make it any easier. She's manipulating us, and I hate being manipulated."

"She's not manipulating us. She's putting her cards on the table. She's trying to persuade us with facts. I trust she'll do everything in her power to make my dreams come true. I feel much more confident that my dreams will come true if I share you with Kaitlyn than if I don't. I very much want to live my life with you, but I also want to live my life with Kaitlyn. We're so close, I want to continue this closeness, and I think we will under Kaitlyn's proposal. So I want to share you with Kaitlyn. You don't have to commit to doing it now, but at some point, you'll have to decide on it. What do you think?"

What did I think? I stopped for a moment to clear my head. I put away my anger over Kaitlyn talking Joanna into cheating on me and dumping me. I put away my initial rejection of the idea as being too weird to work. Would I like to be shared by two beautiful, wonderful women that I loved and who loved me? Of course I would. I was very happy with where things were now, and I didn't like the risk of something new. Punting on the choice until later was appealing. But I thought about Joanna saying she wanted to live her life with both Kaitlyn and me. I wanted a life living with both Kaitlyn and Joanna. I didn't want Kaitlyn to return to being just my sister. And what we were doing now wasn't stable. I could see that only loving Joanna and Kaitlyn equally would work long-term.

"I think we should tell Kaitlyn that we accept her proposal."

* * * *

It was the Saturday before school started, and it had been a stressful day moving all our stuff into our new apartment, but there had been an excitement all day about how we would celebrate being in our new home. As always, Kaitlyn and Joanna had given me only small hints about what they had planned for fun time. And they hadn't given me any idea as to who I was sleeping with tonight. We had ordered pizza delivery for dinner and had eaten as we put things away. Once the pizza was gone, the girls had retreated to Kaitlyn's bedroom. I sat on the couch and waited for them to come out.

I heard the door open, and I looked up to see Kaitlyn and Joanna walk out. They were identically dressed, wearing high heels, stockings, a garter belt and a smile. Kaitlyn's stockings and garter belt were a royal blue whereas Joanna's were a bright orange that looked better on her darker skin. Kaitlyn had her hair braided like the first time we had made love - a crown on the front and sides, and a waterfall in the back - but this time with royal blue and orange silk ribbons in her hair. Joanna's hair was braided in a simple crown, the first time she had had it braided since we had started dating, and she also had royal blue and orange silk ribbons in her hair.

I looked over Kaitlyn and Joanna, savoring their beauty. "You two look so beautiful. I'm the luckiest guy in the world."

Kaitlyn said, "You are," and both girls laughed.

"You two look good enough to eat."

"Promises, promises," said Kaitlyn.

Joanna laughed and added, "You're overdressed," and started pulling down my shorts. Kaitlyn started pulling up my shirt.

I laughed. "I am."

Once the girls got me naked, they pulled me over toward the couch. They were sitting on it, and I was standing between them.

Joanna said, "We're going to try something new."

Kaitlyn eased my cock into her mouth, taking about half my soft length in.

I asked Joanna, "Something naughty?"

Joanna smiled while Kaitlyn slowly pulled her head backward, running her marvelous lips down my cock until it was freed from her mouth. "Something very naughty," Joanna said before moving her head toward my rapidly hardening cock. To my surprise, Kaitlyn guided my cock into Joanna's mouth. This was the first time they had alternated while giving head.

Kaitlyn said, "I know we spent the last few weeks working out the rules for when we started sharing equally, but we're going to change some of the rules." The rule that the girl I wasn't going to sleep with had minimal physical contact with me was clearly out the window for at least tonight.

Kaitlyn watched Joanna suck my cock, and when it came clear of Joanna's mouth, Joanna held it out for Kaitlyn. Kaitlyn paused for a moment.

Joanna said to me, "There's a natural revulsion to taking someone's saliva into your mouth. We hadn't realized that when we discussed doing this." She turned to Kaitlyn. "It wasn't that bad once I got him in my mouth."

Kaitlyn looked at Joanna for encouragement, and then to my cock. She opened her mouth wide and took my cock in. Once my cock was fully in her mouth, I said, "You two are amazing."

Joanna smirked. "And naughty."

In the last three weeks, we had done several dry runs of the girls sharing me equally, so I thought I knew what to expect tonight. But I should have expected Joanna to come up with a curve ball.

I asked, "So what are the rule changes?"

Kaitlyn pushed my cock into Joanna's mouth. She said, "We haven't completely decided. But we have decided to surprise you with them." Her eyes twinkled.

One of the things I had learned to accept was that the girls were in charge. They had to deal with the natural jealousy that should tear any sharing relationship apart. It was pretty damn easy for me to be with whoever I was assigned to at the moment.

The girls alternated sucking my cock, taking it deeper and deeper into their mouths each time. They grew more comfortable with going after each other and soon developed a pretty good rhythm. Finally, I said, "I'm wanting to cum someplace besides a mouth."

Joanna smirked. "Are you saying you want to fuck someone?"

"Hell yeah. I haven't fucked anyone in days." The girls had wanted tonight to be special, so they had cut me off for the last few days.

The girls stood up, Joanna grabbed my cock and led me toward her bedroom while Kaitlyn followed along behind. When I got to the bedroom, the covers were pulled back on the bed and a beach towel was lying in the center. I had never fucked Joanna or Kaitlyn in front of the other - I had always gone with one of them into their bedroom and closed the door - so this was definitely a rule change. I wondered how things would play out.

As we got to the bed, Kaitlyn asked Joanna, "Do you want me to go first?"

"No. I've got something special I'm looking forward to trying." Joanna moved into the center of the bed and opened her legs. "You said I looked good enough to eat."

I climbed on the bed. "And you still do."

I moved into position and took my first lick of Joanna's pussy. I then felt Kaitlyn's hand on my back. As she rubbed it, Kaitlyn said, "Give my best friend a good licking." 'My best friend' had become Joanna and Kaitlyn's favorite way of referring to each other whenever it involved sex.

I went to town on Joanna's pussy. She was wetter and more responsive than our usual nights in bed, but not as wet and responsive as on our usual fun nights. But I wasn't complaining about what we had done for our warm-up. As I licked on Joanna's pussy, Kaitlyn stroked my back and made the occasional encouragement. It was an odd feeling, having Kaitlyn rooting me on to make Joanna cum.

And then Joanna was cumming. As always, she came quietly. When I moved my head away from her pussy. My face was coated with her juices, so I wiped it on the towel. I moved to fuck her in the missionary position. If Joanna wanted another position, now was when she'd let me know. She didn't say anything, but instead rotated her hips back and brought her legs up so they rested on my shoulders. She said, "I thought I'd try a new position for our first fuck in our new apartment."

I said, "You're such a naughty girl." Joanna smirked. "I've never had sex like this before." Joanna laughed silently. "And you're beautiful. I like your hair braided like that."

Joanna looked down bashfully. "Thanks."

I guided my cock to Joanna's pussy, and I was in her. I started fucking her slowly. Having her legs on my shoulders meant I was fucking her at an unusual angle. Fucking in this position wasn't very different from fucking in the missionary position, but it was different enough to be fun.

I saw some movement and looked over to see Kaitlyn take Joanna's hand. I looked at Kaitlyn; and she gave me a smile, letting me know she approved of me fucking her best friend.

Joanna looked over at Kaitlyn and said, "Cum with us."

Kaitlyn shifted position so she could spread her legs wide comfortably. Soon she was rubbing her pussy with her right hand as she held Joanna's hand with her left. Once she started that, I looked back at Joanna, and she gave me a smile.

I said to Joanna, "I love you." As I had allowed my love for Kaitlyn to grow unconstrained, I felt like I loved Joanna even more. I definitely didn't have a fixed amount of love. If anything, the more I loved, the more love I had to give.

I was really getting into fucking Joanna now. I definitely liked this angle, the way I towered over Joanna which made me feel more physically dominating than in missionary. Joanna and I were panting now in time to the sound of the bed rocking. Kaitlyn was moaning lightly as she jilled herself. Joanna looked up at me and said, "A little sound...pant...track for...pant...our fuck."

I chuckled lightly and replied, "You're so naughty."

I could tell Joanna was getting turned on by having me fuck her while Kaitlyn masturbated next to us. I adjusted our rhythm to match Kaitlyn's moans. I said, "I love fucking you," while continuing to steadily thrust in and out of her. I did love fucking Joanna. I loved her creative and adventurous nature. Sex would never be boring with her.

Joanna said, "I can't hold this anymore," and moved her legs down from my shoulders. I stopped for a moment, so she could shift into the missionary position. Once she did, she asked me, "Or would you prefer doggie-style?"

Ever since I had fucked Joanna over the arm of the couch at the lake house, doggie-style was my favorite position. "Yeah."

I pulled back, slid out of Joanna, and grabbed her waist. With her help, I flipped her over onto her hands and knees. She raised her ass up high for me to mount her and then suddenly reached out to grab Kaitlyn's hand. Kaitlyn continued jilling herself, her moans getting steadily louder.

I slid my cock all the way into Joanna's sopping pussy. I grabbed her waist and started hammering her.

Joanna turned back to look at me, and said, "Cum with Kaitlyn."

I had been getting close to cumming, but I could tell from Kaitlyn's moans that she was a few minutes away. I slowed my assault on Joanna and began doing times tables in my head to distract me. It wasn't much of a distraction - I loved the feeling of Joanna's slick pussy as it grasped my cock while I slid in and out of her; I loved holding her wonderful body and looking at her great legs.

I varied my pace, sometimes going slow and sometimes pounding Joanna. The variety kept up my enjoyment while distracting me enough that I kept my orgasm slightly distant. I listened to Kaitlyn while staring at Joanna's smooth, well-toned back.

I heard Kaitlyn's moans reach a crescendo. I grabbed Joanna firmly and hammered her hard until I went over the edge. My first spurt shot into Joanna as I heard Kaitlyn make the gasp she did when she was cumming. I steadily filled Joanna with my cum as Kaitlyn came while holding hands with Joanna.

When I finished, I pulled out of Joanna and lay down between her and Kaitlyn. Our first threesome fuck had been awesome, both physically and emotionally satisfying. I felt drained but also on cloud nine. I couldn't picture it getting better than this.

I lifted myself up, looked to my left and right and saw that both girls were lying on their backs. I got on my hands and knees and bent over Joanna to give her a soft kiss before moving over to Kaitlyn to give her the same. I alternated kissing the girls, enjoying the subtle differences between their lips and kissing technique.

Joanna said, "Lie on your back." She gave me a wicked little grin, so I knew she had something fun in mind. I lay down, wondering what she had planned.

Joanna got on her hands and knees and moved so her chest was over mine. She gave me her mischievous grin before lowering herself, so her nipples lightly touched my chest. A thrill shot through me. Joanna slowly dragged her nipples about a foot down my chest. Her nipples moving across me like that felt incredibly erotic, and I let out a long sigh while she did it. Joanna sat up and gave me her I'm-so-naughty look before saying to Kaitlyn, "Your turn."

Kaitlyn moved to dangle her tits over my chest, and, as she did so, I admired her awesome tits. They looked even bigger as she dangled them. She slowly lowered herself until her nipples touched me, and another thrill shot through me. Kaitlyn looked up at me and gave me a sexy smile. She dragged her nipples lightly over my chest, which felt even better than when Joanna had done it. She backed away for Joanna to go next.

Joanna moved her tits over my chest again, but this time starting low on my chest. She dragged them upward until she reached almost the top of my pecs where she lifted them off my chest. Instead of sitting up, she continued upwards until a nipple was right over my mouth. She slowly lowered herself as I opened my mouth wide. Once her tit was well within my mouth, I grabbed it with my lips and sucked on it. She let me suck on it for a few seconds before sitting down next to me.

As soon as Joanna sat down, Kaitlyn moved to dangle her tits over my chest. While she was doing so, Joanna grasped my now-firming cock. As Kaitlyn dragged her nipples up my chest, Joanna stroked my cock. Jesus, did that feel great! Kaitlyn moved upwards and dangled her tit over my mouth. I again opened my mouth wide. She lowered her tit into my mouth, but when I went to suck on it, she pulled it out of my mouth and chuckled. She dragged her nipple along my lips until I opened my mouth again. The whole time she was doing this, Joanna was stroking my cock. I opened my mouth again, Kaitlyn lowered her tit into it, and this time she let me close my mouth on it. I sucked on her tit as Joanna's hand steadily slid up and down my cock. I had had vague ideas about what a threesome with Joanna and Kaitlyn would be like, but so far it had vastly exceeded my limited imagination.

Joanna said as she held my now stiff cock, "He's ready to fuck again."

I moved so Kaitlyn could lie down on her back in the center of the bed. She preferred the missionary position. She spread her legs and said, "Fuck me." The way she said it was incredibly sexy. My sister was such a sexy woman, and now I'd be making love to her often. We wouldn't be making love every day, but what couple did?

I moved into position, and as I did, Joanna grabbed my cock. "Let me help you two be naughty." She guided it to Kaitlyn's pussy. Joanna seemed to be enjoying watching me make love with Kaitlyn.

I pushed a little way in. I pulled back and pushed a little further in. "Like that, Brandon," Kaitlyn said lustily. She wrapped her legs around mine, pulling me deeper into her on the next thrust. "So good," Kaitlyn moaned. She was great at letting me know how much she enjoyed fucking me.

One more thrust and my full length was inside of Kaitlyn. Kaitlyn held me all the way in her with her legs. Her beautiful blue eyes looked deep into mine. She said, "Fuck me," and I felt her legs relax.

I did as Kaitlyn asked, starting slow. I hadn't fucked her for a week, so it felt good to be back inside her. Her pussy gripped my cock like a soft glove, making every inch that moved in her so pleasurable, not that her pussy felt so different from Joanna's. It was more her sexual presence, the way she could make the simplest thing sexy, that made fucking her so special.

I thrust into Kaitlyn and pulled back; I thrust and pulled back; her legs pulling me harder into her on every thrust.

A small movement drew my attention to Kaitlyn's hand, and I noticed Joanna was holding it. I looked at Joanna, and she smiled at me. She said, "Kaitlyn, I must be the best best-friend ever, since it makes me so happy to see my boyfriend fucking you."

Kaitlyn squeezed Joanna's hand. "You are the best best-friend ever. Are you going to be happy to watch Brandon fuck me when he's your husband?"

Joanna chuckled. "When he's my husband?"

"Oh, yes. He's going to marry you."

I stopped fucking Kaitlyn and shook my head. My manipulative sister was in action again.

Kaitlyn said, "I hope you don't mind if I continue to live with the two of you after you get married."

Joanna laughed. "I'd love for you to live with us after we get married. But Brandon..."

Kaitlyn looked at me, daring me to say something. When I didn't, she said, "Mom's hinted to me a couple of times she'd like you and Joanna to get married someday. I've wanted you two to get married since I saw how cute of a couple you two made. So give it up, you're outvoted."

I snickered. My manipulative sister was pushing things along again. Marriage hadn't crossed my mind. Then I realized that moving in with Joanna was my last big commitment to her, and I should do a new, bigger commitment so that Joanna won't fall into thinking my I-love-you's are just empty words. And I was ready to make a new, bigger commitment to her.

I said to Joanna, "Would you marry me?"
She said in a teasing tone, "I don't know, Brandon. We're so young and we haven't dated all that long. It's rushing things." She turned to Kaitlyn and asked, "Would you be my maid of honor?"

"Of course!"

Joanna looked back at me and smirked. "In that case, I'd love to marry you." Joanna moved toward me and kissed me gently. "Now give my best friend the good fucking she deserves." I pulled back and thrust into Kaitlyn, who moaned in delight. I felt Joanna put her hand on my lower back, and she lightly pushed me forward as I plunged into Kaitlyn. "Fuck her, Brandon. Let me show her how happy it makes me to see you make love to her." Kaitlyn pulled me into her extra hard as Joanna said that, like Joanna declaring her approval of my fucking Kaitlyn made her extra excited.

The talk of marriage had thrown me off for a bit, but now Kaitlyn and I had a great rhythm going. She was pushing her ass off the bed to meet my every thrust, moaning loudly every time. The bed was really rocking now. I happily looked down at my sister as I fucked her. She was so beautiful and sexy. I loved looking at her as I fucked her. And I loved how she was loud and enthusiastic as we fucked.

As I fucked Kaitlyn, I thought about why Kaitlyn would want Joanna and me to marry so much. I could never legally marry Kaitlyn. Marrying someone who agreed to let us be lovers was as permanent as our relationship would ever be. So my proposing to Joanna had made both of them feel more comfortable that I was fully committed to them. I suddenly pictured Kaitlyn coming to mine and Joanna's hotel room on our wedding night, and me reciting with her the same vows that I had recited with Joanna.

Kaitlyn moaned, "Oh, yeah. Oh, yeah." Joanna lay down next to her and they held hands again. There was something about them holding hands that convinced me our ménage à trois would work long-term. I loved them both though they were very different people, and I'd do anything to keep both of them happy. Though it was early to talk about marriage, I knew marriage was almost a certainty.

Joanna reached out and ran her hand along my side. She started lightly pushing me downward on each down stroke and running her hands up and down my backside until I was ready for the next push. Fucking Kaitlyn was awesome in and of itself, and Joanna running her hand over my body was turning the pleasure up to eleven. Sex had never felt this good.

"It feels so good, Brandon. Keep fucking me like that."

It didn't feel good - it felt incredible. As I had already cum, I'd be able to keep fucking for a while. I snuck a look at Joanna, and she was watching us with a happy, slightly excited expression. She continued stroking my backside to encourage me. I thought about a hat trick but decided that wouldn't be fair. And there was no way I'd be able to fuck four times in an evening.

Kaitlyn said, "Faster, Brandon. Faster!"

Her words pushed up my excitement level. It felt so goooood! As I was already fucking Kaitlyn fast and hard, I took her words as encouragement and not as instruction. She always knew exactly what to say to push my buttons. I shifted up higher, so I'd have a little more power to my thrusts. I plunged into Kaitlyn harder than before. She tossed her head back and forth with her eyes closed, her face filled with lusty pleasure. She looked so damn sexy. What made fucking her so incredible was how she was able to communicate how much she enjoyed it.

"Like that! Fuck me like that!"

I continued fucking Kaitlyn hard and fast. Now instead of raising her crotch to meet my thrust, Kaitlyn egged me on by using her legs to pull me harder into her. I was really slamming her now. She was such a great fuck.

Once more, Kaitlyn gushed, "You're so good, Brandon! Soooo goood!" The way she had huskily held her vowels shot a thrill through me.

The excitement was too much. Pleasure swept over me as I started cumming into my sister. A huge smile filled her face as she felt my first spurt explode inside of her. I fired shot after shot into her, a surprisingly big load given I had cum already.

I bent forward and kissed Kaitlyn as I savored the feeling of my cock slowly shrinking inside of her. I was exhausted and spent, but incredibly happy. I pulled out of Kaitlyn and collapsed on my back on the bed. Kaitlyn and I used the towel to clean up our sex juices. After she tossed the towel onto the floor, the girls settled down on each of my sides with their heads on my shoulders. I felt them hold hands and then rest their hands on my stomach. This felt so right as the way to start the next phase in our life; they had shared me as the way to kick off sharing me equally.

I said, "I love you both."

Both girls said at the same time, "We both love you," and then laughed.

I'm the luckiest guy in the world.

Epilogue
Fifteen years later, from Kaitlyn's point of view
I came out of the bathroom of the convenience store and headed toward the front door. As I walked, I saw my brother Brandon supervising my seven-year-old niece Julie and my four-year-old nephew Benjamin as they looked at candy. We had several more hours to drive to the new-and-improved lake house, and candy would help the kids pass the time. Julie saw me and said, "Auntie!" excitedly as she held up the candy she was going to buy. Benjamin did the same. I smiled at them. They were so cute, and I loved them so much. I waved to them and kept going.

I came out the door, walked to the grassy area around the corner from the entrance, and took from Joanna the leash to Squire, their two-year-old black lab. "Tag," she said as I took it.

"Come on, Squire," I said excitedly to the dog. "Let's go for a walk!"

He bounded up and down happily before heading off.

Mom said, "I'll go with you."

"Great," I said, even though I didn't think it was great. "It'll be nice to have company."

Shortly after we started walking, Mom asked, "How did the big meeting go?"

I shook my head. "Good, and yet it sucked." I was a director for a big management consulting company and was angling to become a partner. Yesterday (Friday), all of the women directors, managers, and project leads in our region got together for a day. It was my big opportunity to show my ability to inspire younger female managers. "I feel so fake talking with other women. I'm supposed to convince them that they can work their butts off at our company and have a wonderful personal life at the same time. And I do have a wonderful personal life. But my personal life is so far from what their life is like that describing my personal life to them is not helpful. I live with my brother and his wife, who is my long-time best friend, in the house we co-own, and on weekends I am a soccer mom to their two kids, who I love like they're my own. No one has a setup remotely like that. Instead, they're all miserable. And I know they're all miserable. It's baked into 100% travel jobs. So I feel bad for telling them about how happy I am."

"They're not all miserable, are they?"

"The ones who are lesbians and have a partner at home aren't miserable. All of the straight ones are. Particularly the single ones."

"Your life can't be so different than the other straight women."

"It is. Let me give you a simple example - home cooking. After eating out the whole week, every 100% travel consultant wants to have a home-cooked meal when they come home. For guys who have a wife or girlfriend at home, she'll cook them home-cooked meals. Joanna makes me a home-cooked dinner Saturday, and you make me a home-cooked dinner on Sunday. Joanna frequently makes me lunch on Saturday and Sunday. So when I go back to the client's site, I'm ready for another five days of ordered meals. For straight women, none that I know of have a husband or boyfriend who'll cook them dinner. The vast majority of the time, if they want a home-cooked meal, they have to cook it themselves. They don't have the energy to do that, but they don't want to order another meal. So a lot of them eat crap the whole weekend." I shook my head. "And it's like that down the line. Women, particularly single women, try to pack a whole week's worth of domestic responsibilities into a weekend, and they just can't do it. They wind up miserable. Whereas I only have a few domestic responsibilities to do on the weekend, all of which I enjoy."

I knew Mom was unhappy about my life, and I was wondering when she'd get around to expressing it. Again.

"I think it's great that Joanna does so much for you. And I'm glad you enjoy spending time with Julie and Benjamin." I knew what was coming next. "But you need to spend time away from all of them. Establish your own life. Date someone. You're thirty-four. It's time for you to settle down with someone. Your biological clock is ticking. I want more grandkids."

Boom! There it was. Again. "I'm aware of how old I am. I've been busy building a successful career. If I had settled down with a guy, I wouldn't have had a baby by now. But I think I've finally reached the point in my career where I could have a baby without setting my career back. I don't think I need to find someone to settle down with to have a kid. In fact, I think I'm much better off having a baby while I'm living with Joanna and Brandon."

My mom took in a big breath. This was not the answer she was expecting. I had only recently had discussions with Joanna and Brandon about having a baby and hadn't shared with Mom what we had agreed to.

"What do you mean?" Mom asked slightly indignantly.

"When I have my baby, assuming I can get pregnant, Joanna will raise him or her when I'm on the road, just like she raised hers. I won't have to quit work. I won't have to stop doing 100% travel. If I were married to Bill 100% Travel Consultant, I'd have to quit my company before I make partner, and partner is where you make the big bucks. I'd get a local job so I wouldn't have to travel, and I'd put my kid into daycare. And they'd get sick all the time - I've heard the horror stories. The only way to not do that is to marry a househusband, and they don't interest me. I can't respect a guy who wants to be a stay-at-home dad. Joanna is a great mom, we agree on how to raise kids, and we'd split raising my kid just like we split raising her kids."

I looked at Mom, and she was frowning. I had hit a sore point. She didn't like Joanna and me splitting raising her kids.

"I think what you and Joanna do is weird. It makes me very uncomfortable."

"Joanna spends all of her week watching Julie and Benjamin. When Saturday morning comes around, she's ready for a break. And I'm ready to spend lots of time with my niece and nephew. So I step into the soccer mom role and let Joanna do what she wants. She likes being more like a grandma on the weekends. And I love being a parent to Julie and Benjamin."

"So the kids are with you and Brandon on the drive to the lake house, and Joanna is riding with us."

"Yeah. She's exhausted by Saturday morning from watching the kids, so Brandon and I take them everywhere on the weekends, letting Joanna recover. Including this trip. And on Sunday evenings when I leave, she's ready again to be a full-time mom."

"She's not exhausted by Saturday morning with Julie in school now."

"She's not exhausted as she used to be; they aren't as draining now that they are older. But it's summertime, and she has both kids full-time again. By Saturday, she's ready for a break."

We had had this discussion many times, and Mom never got more comfortable with our setup.

Tonight, she was going to get a lot more uncomfortable.

* * * *

"Wow!" I said as the lake house came into sight. Brandon and I had paid for the old lake house to be torn down and a new house built in its place. The new house was built on stilts like the old one, but that was the only obvious commonality. It was much bigger and its glass-and-wood-wall look was much more modern and appealing. Brandon had come out several times to check on its construction, but this trip was the first time for everyone else.

We parked the cars underneath the house and started pulling out boxes. Before the old lake house was torn down, we had boxed everything useful in it and stored it at our house. It was time to carry all the boxes into the new lake house. All the adults grabbed a box and climbed up the new, grander stairs.

Brandon unlocked the door at the top, and we all said "Wow!" as we walked in. The new lake house was beautiful. It had a large grand room in the center with five doors and a doorway leading off. The doors led to bedrooms, each of which had a large window. The doorway led to the kitchen. The side of the house facing the lake was all windows and glass doors. The dining area was just inside the glass doors, meaning we'd have a gorgeous view as we ate. The lake house still had a big wrap-around deck, but it was set lower than the floor of the house so it wouldn't obstruct the view.

"This is amazing!" said Mom.

"They did a marvelous job," said Dad.

Brandon said, "It cost a pretty penny. Now that you've seen it, I hope you understand why Kaitlyn and I wanted the title to the property before we sunk this much money into it."

"I was totally fine signing over the title to you," said Dad. "I wanted this house to continue in the family. And I'm thrilled you and Kaitlyn were willing to invest the money to turn this place into something spectacular. You two taking ownership of it before investing a lot of money into it makes total sense. Your aunt and uncle were in total agreement in turning the title over to you two. They'll be thrilled at how nice this place is now. It was so showing its age at the end."

"Oh, that kitchen." Mom shivered. "It still had the original appliances."

We moved into the kitchen and everyone oohed and aahed over the shiny appliances and the big work area.

Brandon said, "Enough gawking. We've got a lot to do before it's time to tuck the kids in bed."

* * * *

Once I had tucked Julie into bed, I joined the rest of the adults at the dining table. Joanna gave me a brief look and a slightly forced smile. I could tell she had done her best to be a good hostess and to put Mom and Dad in the best mood possible.

Brandon was sitting at the head of the table, with Dad to his right and Mom to his left. Joanna and I moved to stand behind his chair. It was time for Brandon to deliver the speech that we had all agreed to.

"We have some big news to tell you. You might already know or suspect this, but it's time to get it out in the open. I won't beat around the bush." He took Joanna's hand. "Joanna and I are happily married." He took my hand in his other hand. "After mine and Joanna's wedding, we did a similar service to marry Kaitlyn to me. We consider Kaitlyn also to be my wife and also a parent of Julie and Benjamin. Kaitlyn and Joanna have shared me since the three of us rented an apartment together at college. The way they share me now is that when Kaitlyn is home, she's my wife and the mother of my kids. When she's traveling, Joanna is my wife and the mother of my kids. This week, Kaitlyn will be my wife. She'll be sleeping with me at night and at nap time." Brandon squeezed my hand.

Mom and Dad's mouths were open. Finally, Mom said, "You aren't serious, are you?"

"We're very serious," said Brandon. "In a little while, Kaitlyn and I will adjourn to the master bedroom for the night."

"Come on," said Dad. "This is nonsense talk." Dad looked at Mom. "Don't you agree, Stacy?"

"Absolutely, JR."

"It's not nonsense talk," said Joanna. "It's how we've been living. And we're very, very happy living this way."

Mom asked Joanna, "Why would you share Brandon with Kaitlyn? Don't you love him? Don't you want him for yourself?"

"I love Brandon very much. We have a wonderful life together. And we have this wonderful life together because of the money Kaitlyn makes. She shares all she makes with us, and, in return, I share Brandon with her. She has the career she's always wanted, and I get to be a stay-at-home mom in a beautiful house like I always wanted. By sharing Brandon, we each get the life we want."

Mom replied, "Sharing your husband can't possibly be the life you want."

Joanna shrugged. "It's easy sharing Brandon now. Two nights a week, I sleep by myself and get to sleep in. I actually look forward to it. Brandon and I make love once a week on Sunday afternoons when Kaitlyn takes the kids to the park. If she didn't live with us, we wouldn't make love any more often and possibly even less as I'd be so tired."

Squire pushed his head under my free hand. I started petting him. Brandon, Joanna, and I had decided it was best if Brandon did the initial announcement and Joanna then present the advantages of our double marriage. We kept going with that plan.

Dad said gruffly, "So it was difficult at some point."

Joanna replied, "I wouldn't say difficult. There were definitely some days when it was Kaitlyn's turn and I wanted Brandon with me. It wasn't until Kaitlyn started working as a management consultant that I saw the big benefits of the three of us living as one. But all three of us have always communicated well and did all we could to make it work. And now, I can't imagine not having Kaitlyn as a fellow wife."

Mom asked, "What do Julie and Benjamin think of this? It must be terrible for them."

"It's what they've grown up with," said Joanna. "We've never hidden from them that Brandon sleeps with Kaitlyn when she's home. When we took the cruise last fall, Julie asked me about it. Brandon and Kaitlyn were staying in one cabin, and I was staying in the adjoining cabin with her and Benjamin. I told her then that Auntie and her dad were married, so it was okay for them to sleep together. I told her she can't tell anyone else that they are married as it was a secret. She seemed fine with that answer. And they like Kaitlyn taking over as their mother when she's home. They're tired of me bossing them around by Saturday morning, and I'm ready to not boss them around. Kaitlyn and I constantly discuss how we parent, so there's no difference in rules when she's being their mom compared to me."

Dad asked Brandon, "What do you think of it?"

"I love being married to both Joanna and Kaitlyn. I love them both. Kaitlyn's income lets me focus on being a good dad and husband. Because I leave at five and don't work weekends, I know I'll never be made a manager. And I'm fine with that. I feel like the luckiest guy in the world."

Mom turned to me. "You could get any guy you wanted. Why would you want to have your brother as your...guy." The last was said with disgust. She obviously wasn't accepting Brandon as my husband.

"I fell in love with Brandon. That week fifteen years ago when we were here with Paul, Brandon kissed my shoulders and neck to show Paul the foreplay he did with Joanna. Since then, he's been the only guy I've ever wanted. I know I shouldn't want to be married to my brother, but I do. He's been a great boyfriend and now husband. Building a life with him and Joanna has made my friendship stronger with her. I love the life I have now. I love my job, and I love being a mom to Julie and Benjamin. By sharing Brandon with Joanna, I get to do both. I wouldn't be able to do that if I was married to any other guy."

Mom and Dad looked at each other. They both looked very unhappy. Dad said to Mom, "This is bullshit, Stacy." He turned back to us and said, "If you're asking us to approve of this, we don't."

Brandon said, "We aren't. We own the lake house. We don't need your financial support. It's great having Sunday dinner with you every week, but we'll be fine if you want to discontinue it. If Kaitlyn and I sleeping together makes you uncomfortable, you can get in your car and go. It'll make us sad if you leave, but we'll still have a great time without you. The kids are looking forward to spending the week with you."
When we discussed this, we made the decision that we wouldn't ask Mom and Dad for approval. The best we could hope for was acceptance. Our hope was that they'd stick around to be with their grandkids.

Mom and Dad looked at each other, now with anger as well as unhappiness. Dad stood up. "Your mother and I will discuss this more in our bedroom."

Mom stood up, and the two of them walked off to their bedroom, closing their door loudly.

"At least they're still here," I said.

Joanna shrugged. "None of us expected them to take it well."

Brandon said sadly, "No, none of us did."

* * * *

Brandon and I were too upset about Mom and Dad to make love that night. In the morning, we got up early to get up before the kids got up. We started on breakfast for everyone. Mom and Dad came out of their bedroom after Benjamin loudly exited his. Mom and Dad continued to look unhappy, but they didn't say anything about Brandon and me. Instead, they focused on Benjamin and, after she came out, Julie. Joanna joined us a little later.

Joanna, Brandon, and I did our best to act like nothing was different, and that seemed to work pretty well. After breakfast, we took the ski boat out and had the kids ride in a "towable tube". It was more like a bright orange couch that we could strap the kids in. They loved it. Brandon and Joanna took turns skiing, and then the kids took another ride in the towable tube. As the morning progressed, Mom and Dad were in a better and better mood. We knew they'd be very unhappy with Joanna, Brandon, and me, but we had hoped that having fun with their grandkids would make staying angry hard. Our plan seemed to be working.

When we went in for lunch. I supervised Julie making grilled cheese sandwiches for her and Benjamin while Mom and Joanna cooked the meal for the rest of us. Once lunch was over, Joanna took Squire and the kids down the stairs while Brandon and I waved goodbye to them. Mom and Dad walked toward the door out with grim, unhappy looks on their faces, but didn't say anything to Brandon or me as they exited the lake house.

* * * *

Joanna took Benjamin with her as she went for a walk with Squire. There was a picnic table halfway between the lake house and the lake with a large pavilion tent around it to provide shade. Julie made a beeline for that. She was carrying a sticker book, a coloring book, and some crayons. Her grandfather went to lie down in a hammock. Her grandmother Stacy followed along and sat down next to her. Stacy saw this as her big opportunity to talk with Julie about what a terrible thing Brandon and Kaitlyn were doing. "Auntie and your dad stayed behind," she said to Julie to bring up the topic.

"Uh-huh. They told me they would." Julie smiled brightly. "Did you know that this fall I'm going to fly to New York City and meet Auntie there? I'm going to go when the school has a four-day weekend for teacher training. It'll be just the two of us. We're going to stay in a super nice hotel downtown, and we're going to see the Statue of Liberty, and we're going to a play on Broadway, and we'll take the subway everywhere!"

Stacy did know about that, but it wasn't what she wanted to talk about. When Stacy didn't respond, Julie went back to her sticker book. Stacy waited a bit until the trip to New York was no longer in the air and then asked, "Do you and Benjamin ever nap in the same bed together?"

"No!" said Julie in a tone that dismissed the idea as stupid. Julie didn't look up as she was busy putting a Disney princess into her book.

"It's not right for your dad and his sister to nap together."

"They told me they'd be napping together this week," Julie said matter-of-factly.

"And your mom told you that they were married."

Julie looked up from her sticker book. "That's a secret. Mom told me to never tell anyone. Benjamin doesn't know. He's not old enough to keep secrets."

"They're keeping it a secret because it's wrong for a brother and a sister to marry."

"I'm glad they're married," said Julie in a slightly defiant tone. "That means Auntie will live with us forever." She grinned widely. "I love Auntie. None of my friends have an Auntie." Julie moved to face Stacy more directly. "Some of them have aunts, of course, but no Aunties. An aunt who lives with them." Julie made a pooh-pooh gesture with her hand. "I have one friend who has an aunt who lives with her. But she lives with them because she doesn't have a job. She's not like Auntie, who chooses to live with us. My friends are envious that I have an Auntie who takes me to so many places and spends so much time with me."

Stacy was taken aback by this. It wasn't the answer she wanted to hear. She tried to get the conversation back on track by asking, "You wouldn't marry your brother, would you?"

Julie laughed. "Of course not. Benjamin is gross. Did you know that dogs will eat their own poop? I can picture Benjamin eating his own poop." Julie leaned forward. "Dad is Auntie's older brother. He's not gross. He always treats her nicely. He never says anything mean to her." Julie leaned back. "Not that he says anything mean to Mom. But I've heard other dads say mean things to other moms."

Julie returned to her sticker book. Stacy felt stymied. She hadn't gotten through to Julie at all.

"When I grow up," said Julie after she unpeeled a sticker, "I want to be just like Auntie. Traveling the country, talking to important business people." Julie placed the sticker. "Also, I want a baby sister." She looked back up at Stacy. "I really want a baby sister. But Mom says that she doesn't want to have another baby. She has two kids and doesn't want to go through being pregnant again."

Stacy wasn't surprised by this news as Joanna had said the same thing to her. Stacy said the same thing she always said when Julie brought up the topic of wanting a baby sister, which she had done many times in the last few years. "You have a baby brother."

Julie frowned. "He's not a baby, and he's not a girl. I want a sister to play Barbies with. Someone to watch Frozen with. Benjamin hates Frozen. Someone I can braid their hair like Mom braids Auntie's hair."

Stacy sighed. She had had this conversation many times with Julie. "Your mother doesn't want another baby, so that's that."

"But what if Auntie and Dad make a baby? Wouldn't she be my little sister?"

"Well...err." Stacy didn't want to get into the distinction between half-sisters and sisters. She didn't want to think at all about Kaitlyn and Brandon having a baby.

"Wouldn't it be wonderful if they had a baby girl?" Julie's face was filled with joy.

Stacy was disgusted by the idea of Kaitlyn having Brandon's baby, but she couldn't bring herself to rain on Julie's parade. "Don't count on such a thing happening."

Julie nodded her head. "They might have a boy instead." She returned to her sticker book and pulled out another sticker. "But it would be wonderful if they had a girl."

* * * *

After everyone left, Brandon took my hand and we walked to our bedroom. I went to the window and peered out to see Joanna and Benjamin walking Squire. One child found, I looked for Julie until I spotted her partially hidden under the pavilion on the picnic table. I then saw Mom sitting next to her. I froze for an instant. I knew Mom would try to persuade Julie that Brandon and me being married was wrong.

Brandon came up behind me and leaned into me as he looked where I was looking. "Mom is talking with Julie. Good. I feel like Mom and Dad are acquiescing about you and me being married, but not accepting it. I think Julie is the only one who can persuade them to accept us." Brandon squeezed my shoulders. "She loves her Auntie and is thrilled that we're married."

"You don't think..." I said cautiously.

"I think it's a risk we have to take. Julie loves you as a parent, and I don't see one talk with Mom changing that."

I looked back at Brandon and smiled at him to show my appreciation for his reassurance. "Then we should start working on that baby sister she wants so badly."

Brandon chuckled and stepped away from me. I checked on Benjamin once more and saw that he was having fun with a stick.

When I turned from the window, I saw that Brandon had a chair pulled out for me. "Have a seat," he said. I couldn't help smiling as I sat down in the chair, even though I felt time pressure - I wanted to complete our "nap" before Joanna and Benjamin got back. I felt butterflies in my stomach at the whole prospect of trying to make a baby.

Once I was seated, Brandon moved my hair out of the way and lightly kissed my neck. Despite how many times Brandon had done this, it still gave me shivers down my spine. Brandon said, "It was fifteen years ago today that I kissed your neck for the first time," and then started kissing slowly down my neck.

I replied, "I loved it then, and I still love it now. It was..." I thought back to that night. "I had never experienced anything like it. It filled me completely with lust." I could feel my nipples hardening from the sexual electricity Brandon's kisses were generating. "I wanted you. I wanted you far more than I had ever wanted any other guy. I had always thought highly of you and had been somewhat attracted to you, but once you started kissing me, I knew I had to have you."

Brandon had reached the bottom of my neck and started moving along my shoulder. When he reached my bikini strap, he started pulling it aside. I stopped him by grabbing my bikini top and pulling it off over my head. Brandon gave me another kiss as he brought his hands around to cup my tits. "You did get me," said Brandon. He resumed kissing along my shoulder. "And now you are my wife."

"I feel much more like your wife now that we've told Mom and Dad." Brandon had reached the end of my shoulder and was now kissing his way back toward my neck. "It was great today acting like your wife in front of someone besides Joanna. Mom and Dad were unhappy about it, but they accepted it, however grudgingly."

"They did. I don't think they'll ever be happy about it, but, hopefully, they'll learn not to be unhappy about it."

"I hope so too." I stood up and moved toward the bed. "And hopefully they won't go nuts when I tell them I'm pregnant with your baby."

"Well, I have to get you pregnant first."

I got a towel out of a drawer while Brandon pulled back the covers. "My gynecologist has done everything she can to prep me to get pregnant this week. I told her I'd be spending a week with an old friend and wanted to get pregnant by him."

Brandon chuckled. "I guess you could describe me as an old friend."

I stripped off my bikini bottoms, grabbed a tube of fertility-friendly lubricant from the nightstand drawer, and moved onto the bed. I laid down on my back and started applying the lubricant to my pussy.

"No foreplay?" asked Brandon.

"The neck and shoulder kisses have me ready. And I want to get to the babymaking."

Brandon moved between my legs. I grabbed his cock and guided it to my vagina. "I love you," said Brandon as he entered me. I loved how his cock felt inside of me, filling me.

"Go slow," I said. The lubricant wasn't as good as my natural lubrication after orgasming.

Brandon pushed forward slowly, pulled back, pushed forward slowly further, pulled back, and then pushed forward until his crotch pressed against mine.

I wrapped my legs around Brandon so he could not pull back. I asked, "Are you absolutely sure you want to knock me up?"

"Absolutely sure."

I loosed my legs so Brandon could fuck me, and he started doing so.

I had never really felt like Brandon's wife. Joanna had the ring. Joanna called Brandon "my husband" to everyone we met. And Joanna had conceived two kids with Brandon. I loved Julie and Benjamin, but being with them made me want to have my own kid even more. My kid to raise with Brandon. Being Brandon's wife openly in front of my parents had made being Brandon's wife feel much more real to me, but I knew I'd never really feel like Brandon's wife until I was holding our baby in the delivery room with Brandon smiling next to me.

"Fuck me, Brandon. Fuck your wife."

Brandon thrust forward harder, filling me with his manliness. I moaned an "Oh!" as he did so. I had my legs wrapped around the back of Brandon's legs so I could encourage him to thrust hard into me. I loved Brandon fucking me. He didn't rush. He put my pleasure before his own, knowing that a worked-up me was hot as hell in bed.

I rubbed my hands over Brandon's chest as he continued fucking me. Thrust! Thrust! Thrust! "Oh! Oh! Oh!" I moved my hands to grab his forearms and squeezed. "This feels so good."

"This feels so right," Brandon replied.

I smiled. How could something that feels this right be wrong?

I moved my legs away from the back of Brandon's legs and then raised my right leg and put it on his shoulder. Brandon grabbed my right thigh with both hands. While I was doing that, I moved my left leg so it was off to the left of my body, spreading myself out as much as possible for Brandon. Brandon started really pummeling me in this position. And I loved it.

I grabbed both of my thighs close to my groin and pulled on them to spread as much as possible. I wanted Brandon to have a good look at my pussy.

"See this pussy. You're going to put a baby in it this week. And then the belly above it is going to swell as our baby grows. Do you want that, Brandon?"

Brandon didn't slow his pummeling of me. "I want that. I want you to have my baby, Kaitlyn."

I moved my hands back onto Brandon's chest. His skin was hot as I continued to rub it. Brandon continued pummeling me. If anything, he was slamming me harder now than before I mentioned his baby swelling inside of me. Whatever doubt I had about Brandon wanting to truly make me his wife by impregnating me was gone.

"I love you, Brandon."

"I love you, my wife."

I dropped my leg down, and we switched back to the missionary position. Again, I wrapped my legs around Brandon the back of Brandon's legs. Brandon fucked me more slowly, more lovingly. I looked up at Brandon's face and could see the pleasure my fucking him gave him. I closed my eyes and relaxed, savoring the pleasure. I knew Brandon would come soon. I knew he'd fill my unprotected vagina with his sperm and they'd begin swimming their way toward the egg that I'd probably drop tonight.

Brandon cried out, and I felt him coming. I felt the warm spurts shooting into me. I used my legs to pull him further into me as he continued pumping sperm into me, trapping him deep within me. I wanted all of his sperm to be inside of me.

"I love you," said Brandon.

"I love you, too."

A warm glow filled me. This was everything I wanted. I had the life I wanted, except for one thing. And now, I was very close to having that one thing.

The week at the lake was absolutely wonderful. That I was Brandon's wife was never mentioned again when my parents were around, just as my sleeping and "napping" with Brandon was never discussed. Not discussing it seemed to be my parents' way of accepting that I was Brandon's wife, and I was fine with that.

Too soon, it was time to fill up the cars and leave the lake house. Too soon, I was flying on a plane to the client's site. That week had a special anxiety. Was I? Was I?

When I got home late Friday night, a pregnancy test and a timer were waiting for me on the counter of the master bathroom. I peed where I should and then went and snuggled with Brandon while telling him about my week. When the timer went off, I looked at the pregnancy test. Positive.

Eight months later, I had Harper. Brandon, my loving husband, was with me all the way through my delivery. Shortly after the baby was born, Joanna, Julie, Benjamin, and my parents visited. Julie was absolutely thrilled to have a little sister. Benjamin got bored quickly. My parents oohed and aahed over Harper as they had done with their first two grandkids. After a while, I told everyone that I needed a nap. Joanna gave Harper to Julie to carry to the nursery. Joanna and Dad walked on each side of Julie to make sure nothing bad happened. Benjamin followed them out. It was now just Brandon, Mom, and me in the room. Mom told me and Brandon, "Your father and I still disapprove of you two considering yourself married, but now that you have a child together, we think you should stay together."

I smiled. I was too tired to do anything else. As tired as I was, what I mainly felt was happy. I was very, very happy.
