Not Dating My Sister
In helping her BFF, we helped ourselves.
This story was inspired by Vegas Wedding but has little in common with it.

"Matt, I need a really big favor from you," my sister Becky said.

My spider-sense started tingling. Becky was going to ask me to do something I definitely didn't want to do. It had lightly tingled when Becky invited me to her apartment for dinner, and now it was tingling big time.

"What? You need help moving someone into your apartment?"

"No. I wish it were that." Becky looked down distractedly. We were sitting at her dining table after having eaten dinner. "Though it might turn into that." She waved her hand in front of her. "No, I don't know how it'll turn out." She looked back at me. "It's about Summer. Or more correctly, it's about Steve."

Summer was Becky's best friend since her freshman year. She was married to Steve.

"What about Steve?"

"He's cheating on her. I saw him in a restaurant with a woman, being very friendly with her - very friendly - on a night when he told Summer he'd be working late."

"That's awful." My gut twisted. I liked Summer, and this was awful to have happened to her. "They haven't been married very long."

"A few months until their third anniversary."

"Wow!" I shook my head. I couldn't imagine cheating on a girlfriend or wife, and I really couldn't imagine cheating on a wife so soon. No 'we drifted apart over time' excuse.

"Summer needs to be told. She needs to get out of her marriage as quickly as possible. But..." Becky paused. "Here's the thing - I can't be the one to tell her."

"What do you mean?" Becky was the one who saw Steve. How could she not be the one to tell Summer?

"You see...I've done a lot of googling since I saw Steve with the woman, and what I've learned is that the person who tells Summer is likely to have their relationship with her ruined. Summer's first reaction will be to not believe them and to think that they are telling her a bunch of lies out of spite. I don't want my relationship with Summer ruined. In fact, she'll badly need me once she accepts that Steve is cheating on her."

Danger! Danger! Danger!

Becky leaned close to me. "So, I want you to tell her about Steve cheating on her."

"Whoa! Whoa! Whoa! Why me? Why not someone else?"

"You are the perfect person to tell Summer. You know Steve well enough to recognize him, but you rarely see Summer, so it won't bother you if telling her ruins your relationship with her. Summer visits me every Wednesday evening, and you can drop by this Wednesday, pull her aside, and tell her the news. I don't know anyone else I could have casually meet with Summer to tell her the news. And Summer knows you well enough to know that you are a nice, honest guy who wouldn't tell her a bunch of lies for shits and giggles."

I thought that over. I couldn't see any weaknesses in her argument. "I don't want to do it."

"I know you don't. I know you're a very non-confrontational person. But it needs to be done. I'm not asking you to do this for Summer. I'm asking you to do it for me."

I drummed my fingers on the table. I really, really didn't want to be the one to tell Summer, but I agreed with Becky that if Steve was cheating on Summer then she needed to be told as soon as possible.

"Give me the details. Convince me that you aren't making a mountain out of a molehill."

"Okay. I was out on a date with a guy. He took me to a restaurant I normally didn't go to. As we were walking to our table, I saw Steve and a woman at another table. They were sitting very close together. It was yesterday, Wednesday, which is Steve's day to work late as Summer normally comes over to visit me."

"Why were you out on a date instead of having Summer over?"

"Because yesterday was the only evening we could both be free for a couple of weeks."

"Who was the guy?"

"John Mascorro. Not that it matters as the date was a fizzle. I met him through a dating app." My sister was in a long dry spell in terms of dating. "Okay. So I sit down, and I'm filled with uncertainty. Was that really Steve? Was he out with a cousin or something? After we ordered our drinks, I told my date I was going to the bathroom. As I came back, I took a detour to walk right behind Steve and then to our table. As soon as Steve came into sight, I saw that he was holding hands with the woman. As I was walking toward them, he kissed her. I slowed down as I passed their table and heard Steve's voice. So it was definitely him."

That did sound very incriminating.

"After we ordered, I showed John a picture of Steve and told him where Steve was sitting. I gave him my phone and had him take a picture of Steve and the woman."

Becky pulled up a picture on her phone and showed me. It wasn't a great picture, but it did look like Steve sitting at a restaurant table with a woman.

"I later went to the bar and took a zoomed-in picture of them" - which Becky showed me - "and made a video of them" - which Becky played for me. "Like I said, the date was a fizzle. When I got home, I called Summer and told her about the date. I asked her if she and Steve had taken advantage of her not being able to visit me to do something special, and she told me Steve had worked late as he usually did on Wednesdays."

I was convinced. Summer needed to know.

"Why was the date a fizzle?"

I didn't understand why Becky was so unsuccessful romantically. She was 5'6" with pretty blue eyes and dark blond hair that tumbled down past her shoulders. She had a strong nose and full lips. She had no trouble getting dates, but she always seemed disappointed in the ones she had.

"John lied about his height in the app. I'm sure he lied about his salary. He squawked a lot about taking the picture of Steve and the woman. He bragged a lot to try to impress me, but I didn't know how much to believe as I already knew he was a liar."

Lying got John the date with Becky, but lying kept the date with Becky from being successful. Lesson learned.

"So, how would this work?"

"Saturday, let's have dinner at the same restaurant. I'll walk you through everything there. Wednesday, you come over to my apartment after dinner when Summer will be here." Becky got up, got a magazine, and returned. "You want some ideas on how to decorate your apartment."

"I like how my apartment is decorated." It was a studio apartment, and I was fine with its bare walls.

My sister rolled her eyes. "Your apartment needs more than just furniture." Becky pointed to the magazine. "Find a couple of rooms you like. Take some pictures of your apartment and then ask us about how you could make your apartment look like what's in the magazine. After we've discussed that for a while, ask Summer if you could talk to her alone for a few minutes. You tell her what I just told you and then leave. I'll tell you later what happened."

* * * *

A week later, Becky called me. I had shared the information about Steve the prior night.

"How did it go?" I asked.

"She's spending today looking for a divorce lawyer and this weekend she's moving out. She didn't believe you at first. She didn't want to believe you. I suggested she go to Steve's work and see if his car was there."

"As it should be if he was working late. But it wasn't."

"Nope. So she called Steve, told him that she had picked up some cookies, and asked him to come down and take a snack break with her."

"Oh my god. And he couldn't."

"You got it. He had finished work early and had gone to a bar with a colleague to celebrate finishing a big project. Of course, he hemmed and hawed while coming up with that story. Steve added that he'd leave the bar in a little bit and meet Summer at home."

"Oh, man. I feel so bad, and I'm hearing it secondhand."

"When they were both home, Summer demanded that Steve unlock his phone and give it to her. He tried to weasel out of doing so, but when Summer insisted, he confessed to having an affair with a coworker. A divorced woman with two small kids. It had started at first with him trying to cheer her up because she was having such a hard time. But it wasn't serious, and he still loved Summer and wanted to be with her forever."

"And that didn't go over well."

"She slapped him and then packed up some clothes and spent the night here."

"Well, tell her I'm sorry how everything turned out."

"How about you tell her Saturday? We could use your help in moving her out. Her brother is coming into town late Friday, but more hands would help as we want to get her out of her old apartment as quickly as possible."

"She's not mad at me?"

"No. She's very thankful you told her."

"See! You could have told her."

"I think not. I think it was best the way we did it. I could be the impartial sounding board as she discussed whether to believe you or not."

"Okay. I'll be at your place Saturday morning."

* * * *

"Why so damn early?" groaned Summer's brother when I came into Becky's apartment.

Becky replied, "Because Matt just got off his shift and normally would go home and go to sleep. Matt, this is Kevin, Summer's brother."

Kevin stood up from the floor and shook my hand. Hard. Unnecessarily hard. "Actually, I'm Summer's half-brother. But I consider our blended family my family, and I've always called Summer my sister."

Kevin was tall, probably six inches taller than my 5'10", with short, curly dark brown hair. His body suggested he had played football or basketball in high school, maybe at college.

"Shift work, huh? What do you do?" asked Kevin.

"MRI Technician at a downtown hospital. I work seven pm to seven am four days a week, and I'll pick up an extra shift now and then."

"How much do you make?"

"Enough that I can afford to live in a studio apartment by myself. Still paying off the student loans."

"Want to work in Sales?"

I was surprised to be asked this. "No. No interest."

"I'm the sales manager for a company that sells on-premise scrubs cleaning equipment to hospitals. At the end of your shift, you throw your scrubs into a chute. The next day, scan your badge and the machine spits it out to you all clean and treated to minimize lint. We reduce the amount of lint floating around critical parts of the hospital."

"That's nice."

Summer came out of what was now her bedroom. "I'm ready to go." She was gorgeous even with no makeup on; tall, curvy with full dark brown eyebrows, brown eyes, luscious red lips, and long brown hair that hung down in a ponytail.

* * * *

The day before, Kevin had rented a moving truck near his work and had driven it the two-and-a-half hours over to Becky's place. I rode with him from Becky's to Summer and Steve's apartment. Kevin dominated our conversation.

"How did you get to be an MRI tech?"

"Got a healthcare associates at community college, worked as an X-ray tech for two years, and then went to MRI school for eighteen months."

"How do you like it?"

"It's good, better than being an X-ray tech. A lot of standing on my feet. Going into an MRI is a scary thing, so I spend a lot of time reassuring people while I get them properly positioned to be scanned. I wish that I had better shifts, but I'm the bottom man in terms of seniority."

"Steve's an idiot. Summer is everything you could want in a woman - great looks, a good personality, and a good job. She won't be on the market for long. Every guy in town will want to ask her out."

Kevin paused as if he wanted confirmation from me. I said, "I like Summer. I'm sorry this happened to her."

"Yeah. Cheaters are idiots. My birth dad is on wife number four. Cheated on my mom while she was pregnant with me. I was born between Mom filing for divorce and the divorce taking effect. He cheated on wives number two and three. When it was convenient for him, I'd spend the summer with him. Even as a kid, I could tell Dad's eyes were roaming despite being married. I guess some guys are never satisfied and have to prove that they are still attractive to women even after they are married. My mom is a great wife. It didn't take her long to find a guy who appreciated what a great woman she was, and they've been happily married for twenty-eight years. I call my mom's husband 'Dad' because he's been a father to me, unlike my birth dad. Dad is a caring guy who loves his kids. I think that's what every man should aspire to be."

Kevin talked on and on. He told me about his job, his car (a Porsche), and his last three girlfriends.

"Why did Becky have a spare bedroom?"

"Her roommate moved in with her boyfriend two months ago. Becky couldn't find anyone she liked as a replacement roommate. She makes enough that getting a roommate wasn't an urgent need for her. Worked out nicely for both her and Summer."

"You dating anyone?"

"No."

"How come? A good-looking guy like you? You're not gay, are you? Not that there's anything wrong with being gay."

I was fairly good-looking with a charming smile, light brown hair in a professional cut, brown eyes, and a slim body of average height, but I wouldn't consider myself hot or handsome. Women didn't throw themselves at me. "I'm not gay. I'm new to the city as I moved here six months ago after graduating from MRI school in Florida. Working the shifts I do, it's hard to meet new people." It didn't help that I was introverted.

"If you had more money, I'd take you to a strip club. Strippers are always looking for a new boyfriend who'll spend money on them. Every guy should date a stripper at some point."

"Thanks." I hoped Thanks was the appropriate response. A stripper wasn't what I was looking for as a girlfriend.

* * * *

We arrived at Summer's apartment and loaded up everything she was taking. We took most of the furniture, leaving the waterbed, the dining table, and the TV. We took everything out of the kitchen. We took all of Summer's clothes and bathroom stuff. Steve wasn't there; Summer didn't want to see him again unless she was with an attorney.

After we had hauled all of Summer's stuff up into Becky's apartment, I was feeling woozy. Becky said, "Go to sleep in my bed. Then you can spend the evening with us."

At seven, Becky came into her bedroom and woke me. "We're ordering dinner. Thai." She handed me her tablet. "Kevin's paying. Pick what you want."

I selected my order and then said, "I'll pick it up."

"Are you sure? Kevin's fine with paying delivery."

"If Kevin can pay for dinner, I can pick it up."

"While you were asleep, Summer, Kevin, and I got a king-sized bed for Summer at Ikea, brought it home, and set it up. I hope we didn't wake you while we were doing it."

"You didn't. I slept like a baby."

Becky left. I got up, dressed, and went to pick up the food. We had a nice dinner, and then sat around the table and talked. Kevin and Becky did most of the talking. I think Summer didn't want to talk because she was still in shock about her life being turned upside down.

At midnight, Kevin announced, "It's time for bed."

Summer said, "Sleep in my bed, Kevin. I'll sleep on the couch out here. It's too small for you."

Actually, there were now two couches in the living room, the second one from Summer's place. Both were too small for someone as big as Kevin to sleep comfortably.

"Okay," said Kevin. He winked at Summer. "You don't have to twist my arm."

Kevin and Summer went into her bedroom. Becky said, "You okay?"

"I'm fine. I had a good evening."

"You were quiet this evening," said Becky in concernedly. At twenty-seven, she was three years older than me. We hadn't gotten along great when we were younger, but, after she went off to college, she stopped being bossy and started showing genuine interest in me. She would regularly check to see if I was doing okay, and, if I admitted I was having some sort of problem, she'd try to be helpful with advice.

"I'm usually quiet in groups, particularly with people I don't know well like Kevin and Summer." I stood up. "I'll go home now."

"You don't have to. You can sleep in my bed, and I'll sleep out here with Summer. It'd be like a sleepover for us."

I smiled. "I'm not ready to sleep. Won't be until eight. I've got to keep on this sleep schedule. Everyone tells me that if you get off your sleep schedule for even one day, you'll feel like crap for a week. Besides, my online friends in Japan will wonder why I'm missing."

"Okay," said Becky tenderly as she hugged me. "Thanks for everything. Thanks for telling Summer. Thanks for keeping what I told you a secret. Thanks for helping out today."

"No problem."

* * * *

Two and a half weeks later, Becky called me. "I have a favor to ask of you."

"Oh, God! Not again!"

Becky laughed. "This isn't a bad one. Hopefully, it'll be a lot of fun. Summer has been struggling since she moved out, which isn't too big of a surprise. She's been spending all of her free time cooped up in the apartment. I've been doing the shopping for both of us. Kevin has visited every weekend, and he suggested that we do something fun this Saturday. Are you working?"

"No."

"Kevin wants to do something simple - go to a restaurant and then come home and watch a movie. It won't be a date; just an evening out with friends. He thinks he can talk Summer into doing it if he presents it as a date-lite between him and me, with you and Summer going along for company."

A date-lite? What did that mean? "Do you like Kevin?"

"Umm, no. He's not my type. But we both care a lot for Summer, and I want to see her start getting out. Summer likes you. Not dating-like though. Not that I think she's ready to date yet. Steve cheating on her has really done a number on her."

"I'm your huckleberry. I'll come over Saturday after I wake up."

* * * *

We rode out to dinner in Kevin's Porsche. There was not a lot of legroom in the back seat, so I sat in the passenger seat and the girls squeezed into the back. Kevin spent the drive telling me about how awesome the Porsche was. It has a manual transmission.

"Do you know how to drive stick?" Kevin asked me.

"No."

"You should. Every man should know how to drive stick. You don't really drive unless you're driving stick."

We went to Summer's favorite restaurant, an Italian place. We got a booth with the girls on the inside and Kevin and me on the outside. After we sat down, Kevin ordered a Godfather (whatever that is), and the girls got white wine. When the waiter asked what I wanted, I said, "Water."

Kevin said, "Go ahead and order what you want. I'm paying."

"I want water. I don't drink."

After the waiter left, Kevin said, "How can any red-blooded American male not drink?"

I shrugged. "While I was an X-ray tech, I dated a girl who didn't drink, so I stopped drinking. Saved a ton on dates. After we broke up, I didn't resume drinking."

"Why'd you break up?" asked Kevin.

"I moved to Florida for MRI school. There aren't many MRI schools in the US, so I couldn't go to school locally."

Kevin got a Tuscan steak. The girls split a Chicken Pesto pizza. I got the three-cheese tortellini with lump crab in a light Cajun cream sauce, which was excellent. I shared some with Summer, who was sitting next to me. Kevin did the most talking, and Becky talked almost as much. Summer and I mostly listened. It didn't feel at all like a date between Summer and me, which I was fine with as she was way out of my league. I could see it being a testing-the-waters date between Kevin and Becky.

Kevin insisted on picking up the tab. He strongly gave me the feeling that paying for meals was a part of his shtick, showing off how much money he makes. He wore a Rolex. He talked a lot about expensive meals he had while traveling for business. I didn't find his shtick impressive. If the cost of eating expensive meals was constant travel, then the cost was too high for me. I was fine with dinner at Shoney's or Chili's.
On the drive back home, Kevin had Becky sit in the passenger seat. Summer and I squeezed ourselves into the back seat. As we drove off, Kevin started telling his spiel to Becky about how great of a car his Porsche was.

I said to Summer quietly, "Good choice of restaurants."

Summer shook her head and said sadly, "We shouldn't have gone there."

"Why? The food was great. It had a good atmosphere. I thought all of us had a good time."

"It's a great restaurant, but I kept thinking about different times I had been there with Steve." Summer seemed to be drifting into a bad place.

"Well next time, we'll have to go to a classy restaurant that Steve never took you to. How about Hooters?"

Summer chuckled. "Steve never took me to Hooters."

"Twin Peaks?"

Summer chuckled some more. "Not there either."

I proceeded to name all the breastaurants I could think of. Summer eventually started smiling again.

When I ran out of names, Summer asked, "How many of those have you eaten at?"

"Not many. I only go to one of those places if the guys I'm going out with decide to go there. Every time I go, it's young women with spray-on tans flirting with guys they don't give a shit about to get bigger tips. It's not America at its finest."

Summer gave me a pleased look and then patted my hand. "You're a sweet guy. I'm sorry that I've not been a good date."

"This wasn't a date. At least not for you and me. Maybe for..." I pointed my thumb toward the front of the car. "It was a dinner out with friends for me, and a good one," I said as I smiled at Summer.

"Thanks," said Summer, who returned my smile.

We were quiet for the rest of the drive home. At the apartment, the two couches were in a 'V' in front of the TV, with the point of the 'V' the farthest from the TV. Summer and I sat down on one couch close to the point, and Kevin and Becky sat down on the other couch close to us. Neither couch was large enough for all four of us to sit on. This way, each couple had their own couch to spread out on.

"How about a Rom-Com?" asked Kevin.

The rest of us agreed. Kevin found one, and we all said it sounded fine.

I was on my couch's left edge with Summer to my right. I wasn't planning on making a move on Summer during the movie. Again, she was out of my league, and, as Becky had said, she probably wasn't ready for dating yet. We'd watch the movies as friends. I wondered if Kevin would try to make a move on Becky during the movie.

Ten minutes into the movie, Summer started crying. I didn't hear her cry. I looked over and saw tears running down her cheeks. I asked quietly, "What's wrong?"

"Steve and I watched this movie once."

Kevin was on the far side of Becky from us. He must have heard Summer and I talking, because he asked, "What's up?"

"Nothing," said Summer. "Enjoy the movie."

Kevin got up and came over to Summer and me. "What's wrong?"

"It's a movie Steve and I watched."

"We'll watch something else."

"No. You've already started watching this movie, and it's a good one. I don't want to search for a Rom-Com that I haven't watched with Steve. That'll be just as bad as watching this one."

Kevin said to me, "Take my place."

I got off the couch, and Kevin sat down next to Summer and engulfed her in his arms. "It'll be okay," I heard him say quietly. "I'll be here with you as you watch the movie."

Becky waved to me, and I sat down next to her. Kevin resumed the movie, and the four of us watched it. I also watched Kevin and Summer. Throughout most of the movie, she leaned into him as he slowly rocked her. Eventually, they switched to Kevin putting his arm over Summer's shoulders while she put her head on his chest next to his shoulder and they held hands.

When the credits rolled, Kevin stopped the movie and stood up. "Anyone want something to drink?"

"Coke Zero, please," said Becky.

Kevin turned to Summer and said concernedly, "Coke Zero for you?"

"Yes, please."

I said, "I'll have some water."

As Kevin walked into the kitchen, he said over his shoulder, "Sure you don't want a beer? That's what I'm having."

"No."

When Kevin returned from the kitchen, he moved his head to indicate that I should move back to the other couch. I stood up, and he handed me a Coke Zero and a bottle of water. As I moved over toward Summer, I noticed that Kevin was moving to the other side of the couch from where Becky and I had watched the movie together. Becky moved down with him. Summer started scooting down, so I walked to the far end of our couch. Now, there were probably a dozen feet between each couple, though we could still see each other easily.

I handed Summer her can of Coke Zero and sat down next to her.

"Thanks. I'm feeling better."

"I'm glad to hear that," I said as I twisted off the top of the water bottle.

"Had you seen that movie before?"

"No. I haven't seen a lot of Rom-Coms."

"What did you think about it?"

Summer and I talked quietly about the movie while Kevin and Becky apparently did the same opposite of us. After a while, Kevin put his arm over Becky's shoulders. A few minutes after that, Summer said, "Look. If my brother can put his arm over my shoulders, so can you."

"Oh. Okay." I put my right arm over Summer's shoulders, and we continued talking.

Once Summer and I had finished our drinks, I took our empties into the kitchen and tossed them into the recycling. When I came back and sat down next to Summer, she took my hand and said quietly, "When Kevin proposed this double date, I think he was somewhat serious about dating Becky. He likes her. She's much different from anyone he's dated. And Becky hasn't had a date she's really enjoyed in a long time. So I'm hoping for a little 'Monkey see, monkey do'."

"I'm fine with that," I said as I squeezed Summer's hand.

I wondered if our holding hands was to catch me up to what her brother had done. Was it a way of downplaying that she and her brother had cuddled most of the movie? I had never seen a brother and sister cuddle like that. I had certainly never cuddled with Becky.

I didn't give much thought as to why Summer was encouraging me to cuddle with her, as my thoughts were on enjoying cuddling with a gorgeous woman, which I had not imagined happening at all. I hadn't done anything with a woman since I had moved here. It felt good being with Summer.

Much later, Kevin stood up. "It's midnight. Time for bed or else we'll turn into pumpkins."

I stood up and said, "I'll go home."

Kevin and Summer went into Summer's bedroom. Becky walked me to the door. "Thanks for coming tonight." She asked in a voice full of concern, "How was Summer?"

"She was good. She felt a lot better after watching the movie." I felt it best to not mention that she had watched most of it with Kevin.

"It's just..."

"I didn't make a move on her. She's the one who asked me to put my arm over her shoulders. She's the one who took my hand. She seemed to have a good time talking with me. She seemed relaxed."

"Good," said Becky in a relieved voice.

"I don't think it was a date. I think she wanted to have a quiet, romantic time this evening to help forget Steve, and I was there. But if she wants to do it again, sign me up."

Becky smiled. "Come over tomorrow when you wake up?"

"How about this? I'll come over tomorrow morning at eight with bagels. I'll sleep here, and then I'll spend the evening here."

"I like that. See you in the morning."

* * * *

Sunday was pleasant with Kevin, Summer, and Becky. Summer didn't give me any sign that she wanted any physical affection, so I didn't try anything. However, she seemed much more upbeat than she had at the restaurant. We both talked more than we had last night. Nothing happened between Kevin and Becky.

Monday afternoon, I did an hour workout in my complex's gym. I didn't think anything would happen between Summer and me, but it wouldn't hurt to get in better shape. If not for Summer, then for the next girl.

I didn't work on Tuesdays, so I went over to Becky and Summer's for dinner. After dinner, I asked Summer, "If you don't mind me asking, how is the divorce going?"

"Well. We've split up the assets already. Steve's not fighting it in any way. However, our state has a mandatory waiting period before people can divorce. Many people change their minds during the waiting period and reconcile. So, we can't divorce until we're through that. And my lawyer keeps warning me to be prepared for it to turn nasty at any moment. Divorces are incredibly stressful, and one little thing can set people off, making them act completely irrational. Hopefully, that won't happen, but I'm prepared in case it does happen."

"Sounds wise," I said. "Hope for the best; plan for the worst."

It was a pleasant evening, but I didn't see any magic happening between Summer and me. I enjoyed talking with Becky far more than Summer.

Thursday, Becky called. "Kevin is coming in again. He and Summer want to again go out for dinner on Saturday and watch a movie at home. Would you be okay with that?"

"Sure, but some changes this time. The Porsche isn't a good car for four people. How 'bout we take your Accord? And as I'm not drinking, I drive."

"I agree with you about the Porsche. I'll propose that."

"Okay. I'll pay for the four dinners. Kevin can pay the bar tab."

Becky chuckled. "Not letting Kevin show off this time?"

"I'm sure he'll show off in some way."

"True. If they don't agree to those, I'll call you back. Otherwise, see you Saturday."

"See you then."

Friday, I worked out again. There might not be magic between Summer and me, but, hopefully, dating-as-friends was something we could do. I was looking forward to cuddling with a gorgeous woman once again.

* * * *

Saturday, we went to a restaurant none of us had been to before. It served New Mexican cuisine, as in it served food popular in the state of New Mexico. When we placed our food orders, I told the server, "The meals are on a separate check from the drinks, and bring that to me." Kevin frowned for a moment. Had he planned on paying for everything despite me telling Becky that I was picking up the meals? I had thought that paying for the girls' drinks would have been macho enough for him.

That was the only awkward moment of the dinner. As I was getting more comfortable with Kevin and Summer, I talked more. Summer talked more also. We capped off the meal with sopapillas for dessert, which were delicious.

As we walked from Becky's car toward Becky and Summer's apartment, Becky had us lag behind Summer and Kevin. Once there was some space, she said, "Summer asked for a favor today."

"What?"

"She wants to watch the movie with Kevin again."

"When you say 'watch the movie with Kevin again', do you mean watch the movie with Kevin like you and I watched the movie? Or like she and Kevin watched the movie?"

Becky stopped and turned to face me. "You saw how weepy she was last week when we started watching the movie. That's how she's been almost every day since she moved in. Steve cheating on her out of nowhere has been brutal on her. Everything reminds her of Steve and the life she thought she'd have with him. She's been wondering constantly what she did wrong and if she can ever trust a guy again. You saw how much happier she was after she watched the movie with Kevin like she did. She's excited about watching the movie tonight. She hasn't been excited about anything since she moved in."

I felt bad. I hadn't been around Summer every day like Becky has been. I had no idea what Summer had been like. I said grudgingly, "She was feeling better after the movie was over."

"And you enjoyed her feeling better, didn't you? You smiled a lot while cuddling with her."

I could believe that I had smiled a lot. Cuddling with Summer had been such a pleasant surprise. She was very sweet and oh so gorgeous.

Becky added, "So, we swap dates before the movie, go along with Kevin and Summer having a good time together as they watch the movie, and Summer will be in a good mood for you when the movie is over. You'd be okay with that, wouldn't you?"

Yeah, I'd be more than okay with cuddling with Summer again. "Okay. I'll ignore them during the movie."

"Well, that's good, but it's not THE FAVOR. She felt awkward with us seeing her and Kevin cuddling. So, she asked that we mirror what they do."

"Say what?" Was my sister asking me to do what I thought she was asking?

"It would only be putting your arm over my shoulder--"

"No. Absolutely not."

"What was the bad result of Kevin and Summer doing what they did last week? Did they blow up? Did they become sex-crazed freaks? Were they all over each other Sunday?"

I sighed. "No."

"They didn't do much. I had friends do much more in middle school. And nobody will ever know. Last week, Summer was affectionate with Kevin, which helped her forget about Steve. Now, she feels vulnerable about having done that because you or I might tell someone what we saw them do. If we do what they do, then she'll be safe from us ever talking. Mutually Assured Destruction if anyone tells."

Cuddling with my sister seemed so wrong to me, but the way Becky laid things out made it seem reasonable. "I don't know."

"It will only be putting your arm over my shoulder and holding my hand, and it will only be during the movie. After the movie ends, you'll go to Summer. You want her to be in a good mood when you go to her, don't you? And the next morning, we'll pretend it never happened."

It still seemed wrong to me. At the same time, I knew Becky would keep arguing with me until I gave in. It was too important to her to accept defeat. "I trust you, Becky. If you're okay with it, I'm okay with it."

* * * *

Summer picked the Rom-Com this time. The layout was me, Becky, the space between the couches, Kevin, and Summer. Once the opening credits started, Kevin had his arm over Summer's shoulders and was holding her hand.

I looked at Becky. It was our last chance to back out. She shrugged at me. I put my arm over her shoulders and held her hand. It felt very...I don't know. Odd? Odd but nice? I liked Becky. She was an attractive woman. Not as gorgeous as Summer, but still damn attractive. Better looking than any girl I had dated. My body didn't care that the girl I was cuddling with was my sister. It had the same reaction as when I had done it with Summer.

About a third of the way into the movie, Kevin and Summer changed positions, twisting to partially face each other. Summer put her legs over Kevin's right leg. Kevin wrapped his arms around Summer. She put her head on his chest close to his shoulder.

I looked at Becky. She shrugged, and we moved into the same position. My heart started beating faster. It was amazing holding my sister like this. It hit me how beautiful and desirable she was. When Kevin and Summer went back to how they had been initially, I was glad to change positions.

The movie was a good Rom-Com that left you wanting to fall in love with someone. And here I was, holding hands with my sister. Not someone I should want to fall in love with. Regardless of how wonderful she was.

When the final credits started, I expected Kevin to get up. Instead, he moved him and Summer back into the position where she had her legs over one of his. Kevin kissed her. And kissed her again. And again.

I looked at Becky. We had not discussed kissing. She looked as surprised as me. We didn't want to go there, right? I thought at her.

And then Becky turned to me and kissed me. It was a slow, soft kiss. My heart felt like it exploded. Electricity flowed through my body. This was so wrong, but it felt so right. I met her for the next kiss. And the next kiss...

Kevin stood up. "What drinks do people want? Two Coke Zeros and a bottle of water again?"

Becky and I moved away from each other like we had been caught doing something we knew we shouldn't be doing. Which we were.

"Yes, please," said Becky.

I gave Kevin a thumbs up. I didn't think my voice would work.

While Kevin was in the kitchen, I unsteadily stood up and moved over to the other couch. Summer slid down to the other end. I stood waiting until Kevin handed me the bottle of water and the can of Coke Zero. I sat down next to Summer and handed her the can. Instead of opening it, she kissed me; a slow, soft kiss like Becky had initially given me.

"Thanks," said Summer softly after the kiss ended. "Thanks for going along. Do you remember when I told you about my lawyer warning me that people in a divorce act irrationally?"

I nodded.

"That was irrational. But it was wonderful. Kevin is so big and strong; it feels like he's lifting all my burdens off me. I'm much happier now."

Summer kissed me again. We kissed for a long time. The kisses were wonderful, but they didn't have the emotional impact of Becky's kisses. But they were still wonderful.

We took a break and discretely watched Kevin and Becky kiss on the next couch while sipping our drinks. After a while, we turned back to face each other.

"What did you think of the movie?" asked Summer.

I reached out and took her free hand. "I liked it. It was good. At the end, it made me want to fall in love with someone."

"The same for me. And it made me want to kiss Kevin; release with him that feeling of wanting to fall in love with someone. It was wonderful. He's been so good to me. He and Becky. They've gotten me through a very rough time. And now, I'm feeling happy again."

With that, Summer came in for another kiss. We had a short kissing session, drank some, kissed some more, and then finished our drinks. I took the can and bottle to the recycling in the kitchen, and, as I came back, I saw that Kevin was kissing Becky's neck while squeezing one of her tits.

I sat back down with Summer, and we resumed kissing. I brought my hand to one of her big tits, but before I could squeeze it, she moved my hand away. She said, "Not tonight. Tonight, I just want to kiss."

"Okay."

We resumed kissing.

Eventually, Kevin stood up and announced, "It's midnight. Time for bed or else we'll turn into pumpkins."

"Bring us bagels in the morning again?" Summer asked.

"Sure."

Summer kissed me while squeezing my hand. "You're the sweetest guy. I had a great night tonight."

Summer and Kevin went off to her bedroom to get ready for bed. Becky walked me to the door. "You okay?" she asked.

My feelings were swirling all around my head. I let them settle for a moment before saying, "Yeah. Yeah, I am." I had an odd thought. "It felt a little wrong for me to put my arm over your shoulders. You're the big sister. You're the one who's looked out for me. I don't think it works as well for us as it does for Summer and Kevin."

Becky nodded. "I'll think about that." She kissed me on the lips. "See you in a while."

* * * *

Sunday, we again reverted to being just friends again. The only difference this Sunday from the prior week was that both Kevin and I got pecks on the lips from both girls when we left.

Kevin said, "Let's do it again next Saturday," as he headed out the door.

Monday, Becky called me at five. "Have you had dinner yet?"

"No."

"I'll pick us up some sandwiches at Subway and come over to your apartment."

About an hour later, Becky came into my apartment. We had keys to each other's apartment. Our parents, who lived in the same city, also had keys to our apartments.

As we ate, Becky said, "I want to make sure you're on the same page as the rest of us. This is all temporary. One day, hopefully soon, Summer will feel like her old self. When she does, Kevin won't need to come visit every weekend. No more dinner and watching movies in the apartment. Summer won't be your girlfriend. She likes you, but she wants to remain friends with you. I'd like you to keep coming over on Tuesday nights. So don't worry about what happened Saturday night. Pretend like it didn't happen."
"Okay." Becky hadn't mentioned us making out, but I felt that that was what she was really talking about. I shouldn't worry about what we did and should pretend that it hadn't happened. "You said Kevin wasn't your type, but you two seemed to be going at it hard Saturday."

Becky frowned. "It's complicated."

"I work on a complicated machine all day. I can handle being told about complicated things."

Becky frowned some more. "Kevin is close to being a macho guy archetype. He's big, strong and handsome. He's self-confident almost to the point of being a jerk. He makes a lot of money, and lets you know he makes a lot of money. He's very much into conspicuous consumption. The first time he drove me in his Porsche, he spent the whole time punching it and taking tight turns. It was like an amusement park ride. One of my conditions on all four of us going out was that he wouldn't do that to us."

I chuckled. "Thanks."

"I feel like..." Becky thought seriously for a few moments. "I feel like TV and movies portray guys like him as what every woman should want. So many guys I've met through dating apps want to be like Kevin, but Kevin actually pulls it off. But Kevin has more depth to him. He's very loyal to Summer and has made a lot of sacrifices to be with her in her time of need. And frankly, I don't think my friendship with her would have survived this period without him."

"What do you mean?"

"Summer cried all the time. She'd hold herself together at work, and then come home and let all the unhappiness out. It was draining me just being in the room with her. Friday, Kevin would show up, and he wouldn't let her cry. He'd take her for long walks in the park. He did jigsaw puzzles with her. I could recover while he was here and be ready for Summer-duty once he left. So, he's a nice guy despite dancing on the edge of being a stuck-up prick. And he has that appeal that society has programmed me to want, so I enjoyed letting him have his way with me for a bit. And as you and Summer were snogging away, I didn't feel like suggesting that he and I do a jigsaw puzzle."

I snickered. "Yeah, we were."

"And you'll probably be snogging with her again this Saturday. But don't fall in love with her. Because she's gorgeous, she's easy to fall in love with. I don't want things to be awkward between you two once she's back to her old self."

I didn't want to talk about Summer anymore. "So what kind of guy is your type?"

"I want a guy who is open and honest. That's even more important to me after seeing Steve hurt Summer. That's always been important to me. From this episode, I've learned two more things I want in a guy."

"Which are?"

"I want someone loyal to me like Kevin is loyal to Summer. And I want a guy who'll trust me enough to do something they don't want to do because I say it needs to be done. But how do I tell if a guy has those things? Summer thought Steve was honest, loyal, and faithful right up until she discovered he wasn't."

"That is tough."

"I'm an attractive woman, and guys are always trying to impress me. But they almost always come across as fake when they do. Like the guy who lied about his height. I also have too many choices. My inbox on my dating app is always full. I pick one guy to go out with, delete the rest, and it fills back up again. Why date a guy again when he comes across as not quite honest and I can easily find someone else to date? Summer says I'm way too picky."

I thought about saying You are too picky, but thought better of it.

"Hey, tomorrow," said Becky perkily. "Instead of you coming over for dinner, we'll go clothes shopping in the mall."

"What do you mean 'we', Kemosabe."

"Summer is going to throw away all of her non-work blouses and buy new ones. All the old ones have memories of Steve associated with them. She wants your opinion on the blouses she's going to buy."

"My opinion is that she'll look great in anything, and both of you have far better taste in clothes than I do."

"Come on. It's the first time she's wanted to shop since she moved in. What would you do if you didn't go shopping with us?"

Becky had me there. "Not much."

"Meet us at our apartment tomorrow, and you'll drive us in my car."

"Okay."

* * * *

One thing about my job was that there were a lot of slow times. At the beginning of my shifts, I clear up the backlog of planned MRIs. The schedule always got pushed back because of emergency scans. After that, it was only emergency cases. The MRI equipment costs a fortune to buy and operate, and the hospital charges big bucks for each MRI scan, so it financially makes sense to have someone standing around in case someone needs an emergency MRI scan in the middle of the night. Wednesday night, my thoughts were all about the coming Saturday. Blouse shopping had been fun with Becky and Summer, but I think a big part of the fun was the anticipation of making out again Saturday. I felt with Summer, I had moved over the line into the 'friend with benefits' subpart of Friend Zone, and she liked that I was her friend with benefits. All our conversations while shopping had a feeling of flirting. It made my opinion important to her.

I kept remembering Summer saying 'Not tonight' when I had put my hand on her big tit. She hadn't said 'We're not doing that'. She hadn't seemed upset that I did it. She had given me the feeling that we would do that later. Would Saturday be when she let me?

And then there was Becky. We had kissed last Saturday. Would we kiss again this Saturday? More than what we did last time? What did that make me? A brother with benefits?

Or would we not kiss again? Monday, Becky hadn't discussed us kissing and cuddling. Why not?

Why hadn't I brought it up? I knew the answer - it was uncomfortable to discuss. I knew it was wrong and that we shouldn't do it. But I came back to what Becky had told me as we walked to her apartment last Saturday. Did it make us blow up? Did we become sex-crazed freaks? Were we all over each other Sunday? No. As Becky had said, this was all temporary, and we both knew it was temporary. One day, hopefully soon, Summer would feel like her old self, and Becky and I would stop making out and pretend that it never happened.

Did that make it okay that I was anticipating making out with Becky as much if not more than making out with Summer?

* * * *

Saturday morning as I was driving home from work, I got a call from a phone number I didn't recognize. "Matt."

"Hey, Matt! This is Kevin. Is it okay to talk?"

"Sure."

"Could you wake up early this afternoon? Call me when you wake up, and I'll pick you up at your apartment."

"How come?"

"I want to go car shopping, and I'd like you to go with me."

Did I want to go car shopping with Kevin? No. I had no idea why Kevin would want me to go car shopping with him. But he asked, and I wasn't going to be rude and tell him no.

"Sure. I'll call you when I get up."

By three, we were driving in Kevin's Porsche. "I'm looking to buy a Mercedes. I want to try them out today, and I'll buy one later from a dealership close to where I live."

"Okay."

"Would you like to buy this baby?" Kevin patted the dashboard. "It's a lot nicer than your crappy Mustang." He laughed. "I know. It's way out of your price range."

Kevin was so annoying. "Yeah. This car costs way too much for me to buy."

"Hey. I understand why you paid for the dinners last week, but you don't have to. I make more than enough to pay for everything. You don't have to go into debt to try to keep up with me."

I was done with this bullshit. "How much do you think I make?"

Kevin shot a fearful look at me. He knew he had screwed up. "$30K? $40K?"

"With my shift differential, I make $2400 a week."

"Shit! I had no idea."

"In a couple of months, I'll pay off the last of my student loans, and then I'll be debt-free. And that's with me sticking the max I can into my 401K. My Mustang isn't great, but it's paid for. I could buy this Porsche from you, but I don't want to buy this fucking Porsche."

"Sorry." A few moments later, Kevin added. "You must think I'm an asshole. Well, I am an asshole. But I'm trying to do better. That's why I wanted you to go with me today. Let me tell you what's going on with me." He shifted gears. "Steve cheating on Summer hit me hard. It freaked me out. Steve and I were bros. We got along great. I told you about my birth dad, right? On wife number four? For a while now, I've worried that 'Like father, like son'. Out of college, I got a job in Sales and was a success right away. Since then, I've started acting more and more like my dad acted when I was young. I said Steve was an idiot, but I also totally understand why he did what he did. He had one trophy on the shelf, and he wanted another one. Summer wouldn't find out, so no harm, no foul. Part of the reason I've been so supportive of Summer is to scare myself straight." He waved his hand. "Well, not straight. I'm as straight as straight can be. But you get what I mean."

I did not expect anything like this from Kevin. "Have you ever cheated on anyone?"

"Not really, but...when I was a salesman, I'd take customers to strip clubs all the time. I'd pay for them to have a lap dance, and I'd have a lap dance. Good, clean fun. My girlfriend that I was living with would never know. Now that I'm a sales manager for this company, I don't do that. I typically work on the big sales where I have to persuade a VP of a hospital chain, and they aren't into strip clubs. But I still travel a lot, and I have a girlfriend here and a girlfriend there. Nothing serious. I spend a lot of money on them, and they let me fuck them." Kevin pounded the dashboard. "Jesus Christ! Listen to me! I'm thirty years old, and I'm talking about the chicks I boink! God, I need to grow up. Shit, you're how old?"

"Twenty-four."

"Twenty-four, and you're more mature than I am. But being with Summer and Becky is maturing me. Or it's making me want to mature. I've realized that I'm too fucking old to be trying to impress women with my Porsche. And that's all it's good for. It's fucking awful to take four people in." Kevin pointed at himself. "I want to drive us to the restaurant on Saturdays, but the three of you have rightly vetoed that because you don't want to have to shoehorn yourselves into its backseat. So, I want to buy a Mercedes with plenty of room for four. It has to be something nice like a Mercedes. I have to impress people. It's part of my job."

"Okay." Seemed to me as an excuse for spending a lot more on a car than he needed to.

"The whole point of telling you this is I like Becky. I like her a lot. She's completely different from any girl I've dated. I've realized that I never respected any of my prior girlfriends. I respect the hell out of Becky. We're all doing fun and games right now. I'm enjoying it, and it's helping Summer a lot. But I'm hoping things will turn more serious between Becky and me." Kevin waved his hand in front of himself. "I'm trying to become the type of guy that Becky would want to go out with." He looked at me. "Maybe it won't work out. But by being with Summer and Becky, I've realized that it's time for me to start dating seriously. If you had asked me when I was twenty when I wanted to have kids, I would have said before I was thirty. It's time for me to grow up, to stop behaving like my birth dad and Steve, to date a quality girl like Becky, and then settle down and start a family. You talk a lot with Becky, and I don't want you ruining my chances with her by telling her I'm an immature asshole that she should stay far away from."

"Okay."

Should I tell Kevin what Becky said about him? What did Becky say about him? Now that I look back on it, what she said was either contradictory or unclear.

I didn't know what to make of Kevin. Maybe Becky had nailed it when she said that he's a nice guy despite dancing on the edge of being a stuck-up prick, and now he's trying to move away from that edge.

* * * *

We went to dinner at a Benihana. Our chef put on quite a show. For most of the meal, Kevin talked about how he liked the different Mercedes models and what other car shopping he wanted to do. He used me as his backup witness. He made a big deal of paying for the whole check. Still, I was getting used to his antics and was gradually warming toward him.

Back in the apartment, Summer picked out another Rom-Com, and we went to our now usual spots. I put my arm over Becky's shoulders, and she took my hand.

About a third into the movie, Kevin and Summer started kissing. I doubted they'd pay much attention to the movie from then on.

Becky said, "Let's try a new position. Stand up."

I stood up. She slid to the end of the couch close to the other siblings, turned sideways, and put one leg along the back of the couch and one leg on the floor. "Sit down here," Becky said, indicating the spot between her legs. I sat down, and she pulled me back into her so my head was on her shoulder. She put her hands on my chest and said in my ear, "May Big Sis play with your nipples?"

I nodded.

Becky began playing with my nipples. I could hear Kevin and Summer kissing. I turned my head to see them, and Becky leaned down and kissed me. We kissed as she continued playing with my nipples. She circled them with her fingers; she pinched them gently between her fingers; and she pinched them hard between her thumb and index finger. My nipples were rock hard.

When Becky and I took a break from kissing, she whispered in my ear, "Do you like Big Sis playing with your nipples?"

"I do."

"Do you like Big Sis doing this?" Becky leaned down and bit gently on my neck. Electricity shot through my body, and my cock strained against my pants. The movie was long forgotten. God, this was so hot. I loved her being aggressive like this. I loved her calling herself 'Big Sis'. Becky continued nibbling on my neck, and then she moved my head so she could come in for another kiss. I got a glimpse of Summer and Kevin, and they were tongue-wrestling while Kevin squeezed her big breasts.

Becky pressed her tongue against my lips and then slipped it into my mouth. As we Frenched, she played with my nipples again. Now that they were rock hard, she spent a lot of time running her fingers from their base to their tips. My sister was so freaking hot. I had had no idea.

We alternated kissing and Becky nibbling on me. She nibbled on my ear for a while. She would roam her hands over my chest for a while and then come back to my nipples. I was so hard. I felt like my pants were going to burst.

Then I heard music, and I realized it was the song for the final credits. I sat back up. Kevin reached over, turned off the TV, and stood up. "Usual drinks?"

We all nodded.

I looked at Becky, and she looked at me sheepishly. We both knew what we had done was wrong, but we both had loved it, and we both knew we would do it again next Saturday.

I stood up and moved over to Summer, who had slid down to the far end as usual. I asked her, "Happy?"

"Very happy."

Kevin handed me our usual drinks, and I sat down next to Summer. She greeted me with a kiss. We sat our drinks aside and continued kissing. I pushed my tongue into her mouth, and we were Frenching. At one point, she lifted my hand and set it on her breast. I happily squeezed. However, it made me wonder - did Summer want to do each first step with her half-brother first before doing it with me? Not that I was complaining.

Summer's tits were great. Easily the biggest I've ever felt. It was great making out with Summer. But...it lacked the excitement of making out with Becky. I enjoyed Becky being in charge. And even thinking about her saying 'Big Sis' sent an erotic thrill through my body. But it was the best make-out in my life besides the last make-out with my sister.

We took a break for drinks. I confessed, "I didn't see much of the movie."

Summer laughed. It was the happiest I had heard her sound since she moved in with Becky. "I suspected that we wouldn't, so I picked a movie I had seen before. When did you stop paying attention?" I told her where I stopped watching the moving and, while we drank, she told me what I had missed. After we had drunk enough, we went back to making out.

Summer and I alternated making out and drinking. As we drank, we would discretely watch Becky and Kevin. When we had finished our drinks, Becky had her shirt and bra off, and Kevin was sucking on her tits. I wondered - was the cycle that Becky and Kevin would do it first, then Summer would do it with Kevin, and then she would do it with me? Would I be sucking on Summer's tits next Saturday? What would I do with Becky?

At midnight, the festivities stopped as usual. Kevin and Summer went off to her bedroom. Becky walked me to the door. She asked, "You okay?"

"I'm great."

A mischievous smile came to Becky's lips. "Did you like Big Sis being in charge?"

"I LOVED Big Sis being in charge."

"I loved it too."

Becky leaned forward and kissed me. She took my hand and kept kissing me. We kissed until we heard Summer come out of her bedroom to sleep on the couch.

Becky broke off the kiss and squeezed my hand. "Be safe and see you in a few hours."

* * * *

Monday a little before dinner time, I got a call from Summer. After the initial greetings, she asked, "Would you do me a favor? Actually, it's a favor for Kevin."

"What?"

"Could you swap shifts so you have Friday off? He'd like you to be there when he comes in Friday."

"Why?"

"It's a surprise. For Becky. Don't tell her about it."

If it was for Becky, I wanted to be there. "It's short notice, but I'll do my best. How are you feeling?"

"Better!" said Summer perkily. "So much better. Thursday, Becky and I will go to a Bunco night."

"Bunco?"

"It's a dice-rolling game. It's an excuse for a bunch of women to get together to talk and drink wine. People will want to know how my divorce is going. And about why I am getting a divorce. I've not done anything social like this because I haven't felt strong enough to discuss what Steve did, but now I do."

"That's great!"

We talked for a little more and then hung up. I called around and got a co-worker to agree to work Friday for me.

As I ate dinner, I thought about what Summer had said. Why would Kevin want me to be there Friday night? What kind of surprise did he have for Becky? Nothing came to mind.

It was good news that Summer was feeling so much better. It was bad news because it meant we were moving closer to the end of Saturday nights. I knew that they were coming to an end. They were only okay because they were coming to an end. But I didn't want the end to come anytime soon.

* * * *

Friday night, Kevin and I texted each other to arrange that I'd arrive only a few minutes before him. As I opened the door to Becky and Summer's apartment, I called out, "Hey! Hey! Hey!" I walked into the living room. Summer and Becky gave me a friendly hug. No kisses. Very normal.

I said, "Sorry I couldn't go clothes shopping with you Tuesday, but someone wanted to switch shifts."

Becky said, "We didn't go clothes shopping."

Summer added in a teasing tone, "But we will in a few weeks. My clothes closet is still almost empty, and, as I don't have the money to refill it all once, we'll be going blouse shopping probably once a month for quite some time."

I rolled my eyes dramatically. "Ooooh, lucky me."

The girls laughed and then they started telling me about their Bunco night. They were interrupted by a knock on the door.

"That's Kevin," said Summer. She flicked her hand at Becky. "Go answer it."

Becky got up and went to the door. As she was walking to the door, Summer indicated that we should follow her. Becky opened the door for Kevin, and, when he came in, he was carrying his usual duffel bag of clothes in one hand and a large box in the other. The box was probably three feet by two feet by four inches, and it had a ribbon and a big bow. Kevin held it behind his back but couldn't hide it much.
Kevin dropped his duffel bag and said earnestly to Becky, "Becky, you're an amazing woman. You're smart, good-looking, and very loving. Summer couldn't have a better friend than you. And...whenever I leave here, I think about you all the time. Would you be my girlfriend?"

I was shocked by Kevin's question, and Becky looked shocked too. She stood there for a while with her hands clasped in front of her and blinked her eyes several times. Finally, she said, "Kevin, you visiting every weekend is only for a short time. Soon, Summer will be feeling well enough that you won't need to."

"Well, until I stop visiting every weekend, I'd like you to be my girlfriend."

"Kevin..." Becky looked like she was having trouble processing it all. "Look, Kevin, I'm not going to jump into bed with you this weekend."

"I'm fine with that. I'm fine with things not changing very much between us. It wouldn't be fair to Summer and Matt for us to go into your bedroom for long periods, leaving them without their expected company."

I was surprised with how well Kevin was taking Becky's not jumping at the offer.

"How about this," said Kevin. "Take until we leave for the restaurant tomorrow to decide. If you say yes, then it'll truly be a date for you and me. I'll drive your car to the restaurant." Kevin pulled the box from behind his back. "And I'd like you to wear this dress tomorrow night."

"Kevin..."

"The dress is yours, whether you accept being my girlfriend or not. Summer gave me your size, so hopefully it'll fit you. I know you never know until you actually try it on."

Becky took the box. She seemed overwhelmed by everything. She said, "Okay. Give me time to think about it. I'll decide before we leave for the restaurant tomorrow."

* * * *

When I came into Becky and Summer's apartment late the next afternoon, Becky and Kevin were holding hands on one of the couches; the one they always wound up on after the movie was over.

"Guess who decided to be my girlfriend!" said Kevin.

"Congrats!"

I wasn't surprised that Becky had agreed to be Kevin's girlfriend. She had let Kevin suck on her tits last week. She found him annoying at times, but she also liked him. Why not see where things go? It's not like she was having much luck dating the guys she had been dating.

Becky released Kevin's hand and stood up. "Matt, let's talk in my bedroom for a few minutes."

"Okay."

We walked into Becky's bedroom, and she closed the door behind us and indicated to sit on the bed. "I want to talk about what we'll do when we get back to the apartment after dinner."

"Okay."

"I talked with Summer, and I told her that what we did last week would be inappropriate for this week given that I'm now Kevin's girlfriend. Not that it was appropriate for siblings to do in the first place."

Disappointment filled me, and then I shook it off. Becky was my sister, and she was absolutely right in that we've been doing far more than siblings should do.

"What we'll do tonight," said Becky, "is we'll watch the movie with our sibling, but we'll only hold hands this time. Summer says that watching the movie with Kevin will help her feel better. Once the movie is over, the siblings will talk for a while, and then Summer wants to do like last week with you coming over to her and Kevin going over to me. I'm not wild about that. I'm fine with kissing in front of other people but not more than that."

"You did a lot more than kiss in front of Summer and me."

"I know." Becky sighed. "Passion got the better part of me. Back to my point - I'm planning on doing tonight what I did last week, maybe a little more, but I'm not comfortable doing that in front of you and Summer."

"What did Summer think of seeing what you and Kevin did?"

"She liked seeing it. I think it was her idea that Kevin ask me to be his girlfriend."

"Really?"

"I think that's progress. If she's thinking about Kevin and me, she's not thinking about Steve. And she's hated all of Kevin's other girlfriends. They were all bimbos or strippers. And Summer said she'll be much more into having fun with you if she can somewhat mirror Kevin and me." Becky crossed her arms. "I guess what I'm saying is that I'd rather you and Summer not see what I do with Kevin tonight, but I'm going to do it anyway, and I felt like whining about it to you."

I laughed. "Okay. I won't look. Much." I laughed again.

"Asshole." Becky dropped her arms. "Let's get back out there."

* * * *

45 minutes before our reservation, Becky announced, "I'll go change."

Kevin turned to Summer, "Do you want to put on something nicer?" She was wearing one of her new blouses, a fuzzy cotton blouse with large white and blue horizontal stripes, and a pair of jeans that showed off her figure without being too tight.

"No." Summer didn't sound happy.

"Okay."

Kevin was wearing a polo shirt and Dockers. I was wearing a T-shirt and jeans.

A little while later, Becky came out wearing a stunning red satin dress. The top of the dress looked something like a corset with spaghetti straps and lots of lace, the center hugged her hips tightly, and the bottom flowed down to her ankles and had a slit on the side that showed off one of her legs. She was wearing red high-heels to finish the look.

"Wow!" said Kevin as he got up, went over to Becky, and kissed her. "You're a knock-out in that dress." He was right. Becky looked like a model. She had put on makeup that really brought out her good looks.

Becky blushed lightly. "Thanks for giving it to me."

"It's my pleasure. It really is." Kevin turned to me and handed me his camera. "Would you take a picture of us?"

"Sure."

Kevin put his arm around Becky's waist and smiled.

"You make a great couple," said Summer.

Becky smiled...proudly? Like she knew she looked damn fine in that dress and was proud of the fact? It was the happiest I had seen her look with Kevin. I took several pictures of them before handing Kevin back his phone.

We left the apartment, and Kevin drove Becky's car to the restaurant. He told her, "Now that you're my girlfriend, I want to get your opinion before I buy my new car."

Kevin had me take pictures of him and Becky outside the restaurant. As they posed, Becky drew several looks. Again, Becky smiled her proud smile. The four of us sat down in a booth as we always did with the girls on the inside and Kevin next to Becky.

We fell into our usual ordering habits. Becky and Summer were negotiating what meal they would share. Kevin would order the most expensive steak. He'd give his salad to Becky, so both Becky and Summer would have a salad with their meal. I was more of a wild card. I always ordered what I'd order if I was by myself, even though Kevin was paying.

Once I chose my selection, I was suddenly hit with the question of how Becky being Kevin's girlfriend would change tonight. Would we even do the sibling time during the movie? Would we even do the movie? Would Summer and I do a jigsaw puzzle on the dining room table while Kevin and Becky spent time behind the door to her bedroom? If Becky had let Kevin suck her tits before she was his girlfriend, how much more would she let him do tonight?

After we ordered our food, Kevin said, "Oh, by the way, I arranged to work remotely Monday. Brought my laptop. So I'll be sleeping here Sunday night."

A flash of anger went across Becky's face, and then she asked in a dangerously calm voice, "Summer and Matt, could you give Kevin and me some minutes alone?"

Taking the hint, I said to Summer, "Let's go for a walk."

Once we got outside, we started walking around the restaurant. We discussed how the exterior of the restaurant was trying to impart a certain ambiance.

Summer said in a slightly dazed manner. "When Kevin brought up asking Becky to be his girlfriend, I encouraged him to do so. I thought Becky would be thrilled to be his girlfriend. Kevin's such a great guy. They've gotten along so well. And, you know...after movie time..."

If a girl let me suck on her tits, I'd assume she wants to be my girlfriend.

"Has Becky talked to you about how all this is temporary?" I looked around to make sure that no one could hear us. "That it doesn't matter what you do with Kevin and what I do with her because it'll come to an end soon?"

"Yes."

"So I think Becky is afraid that Kevin is expecting something long-term when it's important to Becky that it be short-term."

"Do you want everything to be short-term?"

"I...ummm."

"Let me put that differently. Some of it will be long-term. Becky and I have already agreed that we will keep getting together with you on Tuesdays. Why not add to that her being Kevin's girlfriend?"

I didn't answer right away. Instead, Summer and I walked slowly a little further around the restaurant. I liked being with Summer. I felt like she was fine with me not talking for a while. Rather than being an awkward silence, it was a companionable silence.

"Let's say...let's say that Becky was thrilled about being Kevin's girlfriend. That last night, she had him sleep with her. That tonight, as soon as we get back to the apartment, they retreat to her bedroom while you and I put together jigsaw puzzles. Would you like that?"

Summer sucked in her breath; a look of shock on her face. This was something she hadn't considered. "No," she said softly.

"Maybe Becky needs to keep some distance between her and Kevin, so there's space for Kevin to do the things that help you out so much. You're not ready yet for those things to end, are you?"

"No," said Summer slowly. "No, I'm not."

"Maybe once you're fully over Steve, she'll fully throw herself into a relationship with Kevin."

I doubted it. Becky didn't seem wild about Kevin. She had said he wasn't her type. I had the feeling that, before this weekend, she was fine with killing time with Kevin until Summer was fully over Steve. Now, Kevin was trying to elevate things to a level that Becky wasn't comfortable with.

"Let's go back inside," I said.

Back inside the restaurant, Kevin waived us over. Once Summer and I were seated, he said, "Sorry about that. Did you have a nice walk?"

"We did," said Summer. "Matt is good company. I was hoping our food would be waiting for us."

"I think it's coming now," said Kevin as he pointed to our server carrying a food tray.

After we all had our food, Kevin handed me his phone again. "Take a picture of us with our dinner." Kevin put his arm around Becky and smiled. Becky's smile looked a little forced this time. After taking several pictures, I handed Kevin back his phone. He started tapping away on his phone.

"What are you doing?" asked Summer.

"Sending pictures to Mom and Dad."

Kevin punched away and then set his phone down. He said to me, "I'm paying for everything tonight."

"Sure. Your turn."

We ate our dinners, talking as we did. Kevin and Becky were quieter than normal.

When she was done with her meal, Summer said to me, "May I go to the bathroom?"

"Of course." I got out so she could get out.

When I sat back down, Kevin asked me, "What do you think of Summer?"

My eyes widened. I felt like that was a leading question, and I didn't like where it was leading. I knew I had no chance with Summer and that I had lucked into what I had done with her so far.

"I like her a lot. I'm glad that I've been able to help with her getting over Steve, and I'll continue doing that." And if that meant making out some more with her and my sister, so be it.

"You've been great with her," said Becky. "She's very comfortable with you."

Kevin's phone chirped, and he checked it. He started tapping away on it, ignoring Becky and me. Becky looked like she found this rude.

Summer came back and asked me to slide over. I did and was sitting across from Becky.

"Summer, I got a reply from Mom and Dad," said Kevin as he held out his phone so she could see it. "They want to know if the girl in the picture is really your best friend Becky." He then showed the text to Becky. "When I told them that you were, they said they liked her and were proud that she's my girlfriend." He gave us all a big, relaxed smile. "They've never liked any of my girlfriends before." He set down his phone. "Which isn't too shocking as half of them have been strippers."

"Have you narrowed down your choices for your next car?" Summer asked Kevin.

They began discussing Kevin's latest thoughts on car shopping. Becky and I weren't interested in hearing yet again about Kevin's car opinions, so I asked Becky about her work. She was a project manager for capital projects for a big corporation. She was managing a three-year, $6 million project. It was still early, but she could already see problems. She was in the uncomfortable position of being responsible for the project without anyone answering to her. She told me about the problems she could see and how she was trying to persuade people to address them early.

Becky looked so beautiful. I hadn't seen her so dressed up since prom. She was far more beautiful now with her maturity and competency giving her so much depth and dignity.

The change in seating positions was minor, but it greatly changed the mood. After we had talked separately for a while, we joined back into one big conversation. I knew Summer and Kevin well enough now that I felt comfortable talking more. Summer talked more than what she had in past dinners. Kevin was less dominating and made more funny comments. By the time Kevin had paid, we were all in our usual good mood. As we walked to the car with Kevin holding hands with Becky in front of Summer and me, I again wondered what would happen when we got back to the apartment.

* * * *

When we got in the apartment, Becky said to Summer, "Find a movie while I change into something more comfortable."

Summer grabbed the remote and started flipping through the movie choices. Kevin sat down next to her. I sat down on the other couch and waited for Becky to join me. Becky came out of her bedroom wearing a T-shirt and sweatpants. Her tits swayed more than usual, so she must not be wearing a bra. She turned off the lights, saying, "I want it to be more romantic tonight." When she joined me on the couch, I took her hand while Summer started the movie.

All four of us were good during the movie; no kissing or anything else. When it was over, Summer stopped it, and I turned to Becky. "What did you think?"

"It was a good Rom-Com, funny in parts and leaving me in a romantic mood. I'm looking forward to Kevin coming over here."

I heard a kiss from Kevin and Summer's couch. I turned to see that they were turned toward each other and were holding both hands as they went in for another kiss. I turned back to Becky and said, "Looks like they are going to do more than talk."

Becky frowned. "Summer didn't say anything about this."

"Are you surprised? She's kissed him every other movie night."

"I am." Becky sighed. "But not too much."

Kevin and Summer were kissing steadily. I asked Becky, "Do you want to mirror them? Keep Summer from feeling bad about kissing her half-brother?"

"Do you want to?"

I knew I shouldn't, but I did. "Yes," I said as I took Becky's other hand.

Becky leaned in and kissed me. We quickly started kissing continuously. When I slipped my tongue into Becky's mouth, she pulled back and said, "I'm Kevin's girlfriend. We're only going to kiss. No feels." Becky moved forward and we resumed kissing.

After a while, I turned my head and glanced at Kevin and Summer. They were Frenching madly while Kevin was squeezing her tits through her blouse with both hands. I was strongly tempted to squeeze Becky's tits. We should keep up with Kevin and Summer, right? But I didn't - Becky had laid out what she wanted to do, and I'd respect that.

Our kissing went on and on as Becky and I slid our hands over each other's bodies, always avoiding the sexual places. I wondered how much longer this 'siblings talking' phase was going to go on.

Becky pulled back from kissing me and said in a rush, "I want to play with your nipples. Leave mine alone." Before I could answer, she had put both her hands on my chest with the centers of her palms over my nipples. She started rubbing her hands on my chest in circles, lightly stimulating my nipples. I checked in on Kevin and Summer. Summer was topless, and they were kissing frantically as Kevin mauled her tits. Was Becky aware of what her boyfriend was doing with his half-sister? Did the fact that they were half-siblings make it okay, whereas it'd be wrong for Becky and I to do the same?

Becky wrapped her hands around my neck and pulled me in for another kiss. Once we were kissing, she dropped a hand down to play with my nipple. Kissing Becky was so hot and intense.

After Becky had alternated playing with each nipple for a while as we kissed, she said, "Take off your shirt. I can't take off my shirt, but guys can always take off their shirts."

I whipped off my shirt, and Becky started sucking on my left nipple. I said, "Does Big Sis like my nipples?"

"Big Sis looooves your nipples." Becky switched to my right nipple, and I ran my fingers through her hair as she sucked on my nipple. She then shot up and hungrily kissed me, quickly ramming her tongue into my mouth. Could I squeeze Becky's ass? Would it be okay if squeezed Becky's ass? I so wanted to squeeze Becky's ass. I didn't squeeze Becky's ass.

I had no idea what time it was. I felt like I had kissed Becky a million times but for only a few minutes. If we were in the backseat of a car right now, all the windows would be fogged. Becky and I were so passionately making out. My cock was rock hard. I had never felt so excited with a girl. I took another look at Kevin and Summer. The topless Summer was lying on her back on the full length of the couch, and Kevin was on top of her sucking on her tits while she ran her fingers through his hair.

After a while, I heard Summer and Kevin intensely whispering. Were we finally reaching the end of the 'siblings talking' phase? I kissed Becky with even more abandon, trying to get in as many hot kisses as I could before it came to an end.

I heard Kevin stand up and make a polite cough. Becky and I stopped kissing and turned toward him. I was holding one of Becky's hands and didn't feel like letting it go.

Kevin said awkwardly, "I screwed up tonight. It's time for bed, and I never moved over to Becky's couch like we planned. I'm sorry." He swallowed. "Also, Summer doesn't sleep that well on the couch, so she's going to sleep in her own bed tonight. It's big enough for both of us. We won't do anything we didn't do out here."

With that Summer and Kevin walked into Summer's bedroom and closed the door.

"Well, fuck it!" said Becky. "If he can make out with Summer in her bedroom, we can make out too." She grabbed my hand and looked around. "Move into the corner of the couch and place yourself so I can lean back into you."

I moved so that one leg was on the floor and one leg was along the back of the couch. Becky spun so her back was toward me and scooted back until her shoulders were resting across my chest.

"Big Sis wants you to play with her nipples now."

I put my hands on Becky's tits and squeezed gently. I moved my fingers so that Becky's nipples were between two of them and brought those fingers together to gently squeeze Becky's nipples.

"Oh, yeah. That's what Big Sis wants."

Becky kissed me, and, after a few moments, slipped her tongue into my mouth. We Frenched as I explored Becky's marvelous tits. They felt better than Summer's because I was feeling the tits through only a shirt as compared to a shirt and bra. And, though Summer was more gorgeous than Becky, Becky was hotter. Much, much hotter. Making out with her was utterly amazing.

"Put your hands under my shirt," commanded Becky with almost an ache in her voice.
I brought my hands down Becky's body as she lifted up her shirt. As I slipped my hands under her shirt, Becky said, "As I'm your sister and Kevin's girlfriend, this is as far as I can go."

"That's okay," I said as I squeezed Becky's tits with my hands. They felt so great in my hands. The perfect size and shape. I nibbled on Becky's neck as I circled her nipples with my fingers.

"Big Sis loves this," panted Becky. "You make me so hot." We resumed kissing. The intensity of our kissing had dropped to zero after Kevin made his announcement, but now was ramping back up again.

Becky's shirt steadily crawled up as we frantically made out. We alternated sloppily kissing with my nibbling on her neck and ear, all the while groping her tits while playing with her nipples.

"God, you make me so fucking hot," said Becky as she started to slowly sit up. I pulled my hands out from beneath her shirt. She stood up and pointed to the center of the couch. "Sit there." As I slid over, Becky pulled off her T-shirt. Once I was in place, she got on the couch and straddled me. "Big Sis wants you to suck on her tits."

I didn't have to be asked twice. I immediately latched on to one of Becky's tits and started sucking.

"That's it. Now squeeze Big Sis's ass."

I moved my hands to Becky's ass and squeezed with both hands as I continued sucking on her tit.

"Oh, yes. That's what Big Sis wants. That feels so good."

Becky ran her fingers through my hair as I continued to suck on her tit and squeeze her ass. My hand was on the outside of her sweatpants. I thought about slipping my hands inside her sweatpants but decided to do only what Becky told me to do. That's what I had been doing, and it was working great.

When Becky moved my head over to her other tit, I greedily sucked on it. I loved my sister's tits. Summer's tits were bigger, but they had more of a sag. Becky's tits were perfect.

"This feels so amazing," said Becky. "You get me so hot. We had better stop here, or I might not be able to stop."

Becky climbed off me and picked up her shirt. She asked me, "Stay the night? There's no Summer out here to bother you."

I shook my head. "But there's nothing to do here."

"You could play on your phone."

"Not for seven hours." I raised my hand in a stop sign. "How 'bout I tuck you in?"

Becky frowned and said in defeat, "Okay."

We went into Becky's bedroom and closed the door. Becky went to her closet. "Don't look," she said to me.

I turned away from her. I heard Becky take off her sweatpants.

"Silly, I know," said Becky. "But Kevin hasn't seen me in panties yet, and I feel like I shouldn't let you see something I haven't let him see. You can turn around."

I turned around, and Becky was in an extra large T-shirt with her college name and logo on it.

"Let's get into bed," said Becky. "It's been a long day."

Becky got into her queen bed and laid down on her back in the middle. She pulled back the covers on the side I was closest to. "Would you mind?" Becky asked. "If you put your head on my shoulder instead of the other way around?"

"Sure. Whatever you want."

I laid down next to Becky and then scotched up until I could put my head on her shoulder. She started running her fingers through my hair.

"Becky, you're always so strong. For both Summer and me. But are you doing okay?"

Becky sighed. "I don't know. I think so. But I don't know what the hell I'm doing."

"What do you mean?"

"Let's take Kevin. The elephant in the room. I'm not that wild about him. He seems much more into me than I am into him. But I like him. I loved wearing that dress tonight. I loved him being wowed by how I looked in it. I loved him wanting to have pictures taken with me. And standing next to him with his arm around me, it felt really good. As I've told you, I feel like society has programmed women to want that, and I was surprised by how much I enjoyed it."

"But then..."

"But then, he over-presumed. I'm not some college-age girl who is so impressed by his Porsche, his Rolex, and his paying for everything that I'll let him do whatever he wants. It's fine that he's staying over Sunday. But what if I had planned on working remotely Monday? There's only one large table in the apartment, and I don't think the dining table is big enough for him and me to share. But the biggest thing was the lack of respect. He should have talked to me about staying over an extra night instead of assuming I'd be okay with it." Becky sighed. "I probably came down too hard on him. I told him that we weren't sleeping together Sunday night. And then I told him we weren't sleeping together tonight. I told him to give me time to get used to being his girlfriend."

"It sounds like your relationship is physically ahead of where you are emotionally."

"Before I get into that, let me say that by the time we got into the restaurant, I had decided to give Kevin a real chance. But...one of the stories you hear about women in abusive relationships is that when they started falling for a flawed guy, they said, 'I can change him'. But they never get him to change in the early years of their relationship, and then, after a couple of kids, it was too late. I want to give Kevin a chance, but he's got to change if we're going to work long-term. So that's why I came down so hard on him. And that's why he's sleeping with Summer instead of me."

"Are you jealous of him and Summer?"

"A little. I know that Summer needs him. She's talked to me about how his strength allows her to dump all her feelings of insecurity on him. After every Saturday night, I can see her blossoming more and getting closer to the Summer I knew before Steve crapped all over her. And at this point, I don't see Kevin and me working long-term. Again, I see all of this being short-term. One day, Summer will say she's fully over Steve, and if things aren't better between Kevin and me then, we'll break up. But I will try my best to get my relationship with Kevin working well before that happens, so hopefully we will continue long-term. There's lots and lots of good to Kevin, and he seems to earnestly want to change to be a more respectful boyfriend. And his over-presuming isn't all his fault as I'm confusing the hell out of him by agreeing to do more physically than I'm comfortable doing emotionally."

"Like last week."

Becky sighed. "Like last week."

"Well, whatever you decide to do about Kevin, I'll support you."

"Thanks. Tomorrow morning, you may not want to come back here with bagels. I'm going to read Kevin the Riot Act as soon as he gets up."

"How about this? I'll buy bagels and then after breakfast suggest Summer go for a walk with me."

"That would be perfect."

"Now, enough talking and start unwinding. My online friends in Japan are waiting for me."

Becky chuckled and went back to her running her fingers through my hair. And then she stopped doing that. A little while later, her hand on my shoulder dropped off me. I gave her a little while longer to fall deeper asleep before slipping out.

* * * *

The next morning, Becky and I were eating bagels when Summer and Kevin came out of Summer's bedroom. Kevin made a beeline for Becky and said, "I totally screwed up last night. I'm sorry. Please give me another chance. Tonight, let's watch a movie of your choice, and I'll sit with you through the whole movie and afterward. No getting distracted tonight. Would you please give me another chance and do that?"

Becky sighed. "Let's do that." She pointed her finger at Kevin and said sternly, "But another bullshit move like last night, and we're done."

"Understood. And thanks." Kevin started walking toward the refrigerator. "Can I get you something to drink?"

"No," said Becky. "I'm fine."

Summer hugged me from behind and said, "Thanks for buying these."

"Glad to."

Kevin asked me, "Are these from the most convenient bagel place or the best bagel place."

"Most convenient. I couldn't tell what is the best bagel place."

"Neither could I," said Kevin as he turned to Becky. "Do you have any opinions on bagel shops?"

I stayed until everyone was finished with breakfast. Kevin was doing his best to work himself back into Becky's good graces. "See you all in a while," I said as I headed to Becky's bedroom and sleep.

* * * *

When I came out after sleeping, Kevin said, "I've bought a car. A top-of-the-line Mercedes. Let's go for a ride, and I'll show it to you. I've been meaning to go shopping for some microbrewery beers."

I didn't want to go for a ride in his car. I didn't want to go shopping for beer. But I had the feeling that Kevin wanted to talk to me alone, so I agreed to go.

We got in Kevin's car, and he started driving to the store. As he drove, he pointed out the features of the car. He suddenly said, "You don't care, do you?"

"No."

Kevin laughed. "Thanks for humoring me. At the dealership when I showed Becky the first car, I could tell she didn't care. I asked her, 'Is there anything you'd like in the car I buy?' And she told me, 'Buy what you want.' She's really good for me. Money isn't going to impress her. Being considerate is going to impress her. What do you think of us dating?"

"Nothing for me to think about. It's her life."

"I wanted to tell you to not worry about me being jealous of you and her. I'm fine with it as long as it's about what Summer and I are doing. Fair's fair."

I felt my face get warm. I felt ashamed of what I had done with Becky, my sister and Kevin's girlfriend. His being cool with it didn't make it right. And would he be cool with what Becky and I did after he went into the bedroom with Summer?

"You should ask Summer to be your girlfriend," said Kevin. "I think she'd agree to it."

"I won't ask Summer to be my girlfriend."

"Why not? She's gorgeous. Don't tell me you don't want to fuck her hot bod."

I gritted my teeth. "Because...she's my friend. I really like her. So, I don't want to be her rebound boyfriend. She's going through a hard time, and I could see her thinking having a new boyfriend would help her get over Steve, but then she'd be in a relationship that she'd get bored of quickly. We get along great as friends. I don't think we'd get along great as a boyfriend-girlfriend. She's too far out of my league. If a few months after she decides she's over Steve she's giving me signs that she wants to go out on a date, I'll ask her. But I don't think that will happen. She'll find a guy more at her level, and we'll stay friends.

Kevin said in disbelief, "You're passing up a chance to be with my sister because you want to be her friend?"

"Correct."

Kevin shook his head and then started talking about beers. I didn't care, but I did my best to pay attention. I did appreciate that Kevin went out of his way to let me know that Summer was open to being my girlfriend. And I was glad to not be discussing Becky or Summer.

* * * *

The girls made us dinner. While they were cooking it, Summer took a break and went into her bedroom with Kevin for a few minutes. I sat on the couch and played on my phone. Once dinner was ready, we all sat at the dining table and ate. The food was good, and Kevin and Becky seemed to have made up and were getting along well.

After dinner, we moved to the couches. As Becky was searching for a movie, I asked Summer, "How are you doing?"

"Doing great!"

"Are you progressively getting over Steve?"

"I don't want to talk about that now. Maybe later."

Becky chose yet another Rom-Com. Kevin and Becky held hands while watching it, and, to my surprise, Summer took my hand.

When the final credits started rolling, Kevin kissed Becky. When they kept kissing, I grabbed the remote and turned off the TV. I turned and faced Summer, who had a smile on her face. She said, "I feel like being kissed."

I was in a romantic mood from the movie, so I smiled back at her and said, "I feel like kissing you."

We both leaned forward and kissed gently. Summer took my hand, and we kissed again. I took her free hand, and we kissed a few more times.

"Would you get me something to drink please?" asked Summer.

"Sure."

I got up and thought about asking Kevin and Becky if they wanted to drink. I looked at them snogging and decided they wouldn't appreciate me interrupting them. I got Summer a Coke Zero and me a water. I returned to the living room, handed Summer her can, and sat down next to her.

Summer popped her drink and, after a sip, said, "You asked me earlier how I was doing. I'm getting better. I didn't cry this week, which is a first. Bunco was exhausting but fun, and Becky and I are going again next Thursday. You see me at my best as Saturdays and Sundays are my good days, but Wednesdays are still bad for me." Summer took another sip before setting her drink on the end table. "Enough about me. Let's get back to kissing."

I chuckled, set my drink on the end table next to me, and leaned forward to kiss Summer. We kissed for a while. Our kisses didn't have much passion but were still pleasurable.

Summer stopped kissing me, reached back for the Coke Zero, and, after a drink, asked me, "What did you think of the movie?"

"It was good."

"Put your arm around me, and let's discuss it."

Summer and I both turned so our backs were against the couch back, and I put my arm over her shoulders. She put her left hand on my thigh, and we discussed the movie. We also watched Kevin and Becky. Kevin had his hand inside of Becky's shirt as they Frenched.

Summer and I alternated kissing with talking and drinking. It was very relaxed and companionable. After we finished our drinks, I took the containers to the kitchen. When I came out of the kitchen, I saw that Becky was topless and Kevin was sucking on her tits.

When I returned to Summer, we started making out more aggressively. When she pushed her tongue into my mouth, I put a hand on her tit and squeezed it. The passion was steadily rising, but making out with Summer didn't have the same intensity as making out with Becky. It was Summer and I having fun. We were friends with benefits, though I wondered if there would be new benefits tonight.

After a while, Summer and I took another break. Again, I put my arm over her shoulders and took her free hand. We both looked at Kevin and Becky. Becky's head bobbing up and down on Kevin's cock.

Summer said, "Wow! I want them to get along, but I wasn't expecting them to be getting along that well." She sounded a little angry to me.

"We shouldn't watch."

"True. We should be doing things for them to watch."

Summer pulled off her shirt, removed her bra, and set both of them next to her. She turned toward me, crooked her finger at me, and said, "Come here."

I moved forward, and Summer guided my mouth to her tit. I quickly latched on one while squeezing the other. Summed sighed deeply and then ran her fingers through my hair. I'd never be Summer's boyfriend, but being her friend with benefits was pretty damn good.

I was still sucking on Summer's tits when Kevin announced, "We're going to bed."

Summer pushed me lightly away from her and said, "Time for bed for me as well."

As I watched Becky and Kevin go into her bedroom, I was a little surprised. Becky had told him that he wasn't sleeping with her on Sunday night. But the alternative was Kevin sleeping with Summer, and Becky had apparently decided she preferred her boyfriend to sleep with her instead of his half-sister.

Summer grabbed her shirt and bra, and we held hands as we walked to her bedroom door. "I had fun tonight," she said. "It felt very healthy for me. Thanks. Thanks for being such a great friend; and thanks for being so understanding; and thanks for not judging me for my irrationalities."

Summer kissed me and then went into her bedroom and closed the door.

Tuesday as I was eating breakfast, I got a call from Summer. "Hey! I've decided to sell all my furniture from the apartment. They don't remind me a lot of Steve, but enough that I want to move them on. Could you please join Becky and me at Ikea tonight for dinner and to do some furniture shopping? I want to get an estimate for how much it'd be to replace all my furniture."

"Sure, Summer." Tuesday seemed to be becoming our shopping together evening.

"Would six work?"

"Works for me."

* * * *

We ordered our meals from the cafeteria in Ikea and sat down to eat. "I'm not going to sell the couch," said Summer, who then blushed lightly. All of us were a little chagrined for a moment. The two couches were important, but what we did on them wasn't to be discussed.

Summer talked about what furniture she wanted to sell and what she was thinking of for replacements. "I don't want to spend too much on new furniture."

"Matt," said Becky in an I-want-to-talk-about-something-else tone. "Could you bring your Xbox to the apartment Saturday so you could spend the night?"

"No, Becky. It's not just my Xbox. I'd want my PC as well."

"You could bring your laptop," said Becky.

"I have a laptop, but I don't use it."

"Why not? What's the difference?"

"My laptop is fine for office stuff, but my desktop is much better for gaming because it has a far better graphics card. It, my Xbox, and all their accessories would be a lot of stuff. I don't want to haul it all to your apartment and then haul it all back again."

"Why don't you move in with us?" asked Summer.

"What?"

"Move in with us," said Summer.

"Are you literally suggesting that I move into your apartment full-time, just so I don't have to drive home when I'm there late?"

Summer sighed. "Let me be honest. I'm deeply in debt right now. Steve and I had run up a lot of bills, and I've added the cost of the divorce to that. I want to replace the furniture from my old apartment, but I really don't have the money to do it. Matt, Kevin said that he was impressed by your furniture when he visited your apartment." When my grandmother died, Becky and I both inherited a lot of furniture. "If we were to share my bedroom, my rent would get cut in half. I could sell my old furniture and then have whole new furniture. I don't see any big problems with you sharing my bed as we sleep at different times of the day.

"What about my PC?"

"We'll have to figure out a space for it." Summer got more animated. "I think you living with us would hardly be noticeable. We'd have breakfast together, and then you'd sleep in my bed while we're at work. In the evening, we might see you a little bit before you leave for work."

"What about--"

"There isn't any harm in trying," said Summer, cutting me off. "Bring some of your stuff over Saturday, and we'll see how it goes."

I turned to Becky. "What do you think?"

"It kills a lot of birds with one stone. I've known that Summer has been struggling financially and have wanted to help, but haven't been able to think of anything short of giving her money. I agree that I don't think you moving in will cause any waves. Kevin moving in would be completely different. I don't like you driving late at night on Saturdays with all the drunks on the streets. I'm fine with trying and seeing how it goes."

"Listen," I said. "You two go shopping, and leave me here to think about it for a while."

"Okay," the girls both said. As they were done eating, they got up and left.

I remembered Kevin Sunday asking if I wanted Summer to be my girlfriend. Of course I did! Did I want to fuck Summer? Absolutely! Since our foursome evening out, it's what I've been constantly thinking about. I had a plan and was working to make those things happen.

I was confident that I was firmly entrenched in Summer's Friend Zone, though in the 'friends with benefits' subpart, and I was content to stay there for now. Just thinking about sucking on Summer's tits made me feel ten feet tall. And a possible added bonus to being 'friends with benefits' with Summer was that I was getting 'benefits' from my sister as well. I knew I shouldn't want 'benefits' from my sister, but they were both hot as fuck. I would only try to advance my current relationship with Summer when I was confident that I'd succeed. It would totally suck to make a move on Summer, maybe get a couple of weeks of sex, and then have her dump me and lose being with both her and Becky.
My plan was to exploit the time I was spending with Summer to get to know her a lot better. I had a document on my computer of her likes and dislikes. I knew she liked Rom-Com's, so I had been watching YouTube videos on what made a Rom-Com good and what made a Rom-Com bad. Saturday on the drive to the restaurant, Summer and I had discussed Rom-Com's, and it was the most lively conversation we had ever had.

But I need a half-dozen more common interests like that before I'd feel comfortable with trying to make Summer my girlfriend. I was thinking of starting to drink a beer at restaurants when everyone else was drinking but hadn't thought of any way of making it happen. I had added to my Summer document some research on the best beers they serve in restaurants. I didn't want to drink the cheap goat piss I had drunk in college before I met the girl that I had stopped drinking for.

Given my goals, moving into Summer's bedroom seemed too good to be true. Was there some catch I was missing? Was Summer going to kick me out after a short time and take my furniture? Were Becky and Summer going to murder me for insurance money?

I couldn't see any catches. Financially helping Summer was a winner. 'You need to change clothes while I'm in bed? Go right ahead, Summer.' Establishing that we could live comfortably together would make convincing her to live with me as my girlfriend easier. Moving in seemed all upside.

I took a deep breath. So, I'd agree to move into Summer's bedroom. But I wouldn't seem eager to move in. 'It would be nice not having to drive home late at night. It's worth a try.' That was the ticket.

* * * *

Friday as I was driving home, Summer called me. "We're all set for moving you in. I'll move the furniture I want to sell over to your place. I'll feel better about letting people into your empty apartment than into my apartment."

"That's fine."

"And tomorrow," said Summer anxiously, "instead of driving straight to your apartment from work, could you meet me at a park for a walk? Not a long walk; say a half-hour."

"I'd like that."

We made the arrangements and then hung up.

I wondered where things were going between Summer and me. She had suggested that I move in with her and Becky, and now she wanted a private walk with me. Making out with her Sunday had felt so good. God, I'd love to be her boyfriend. But Sunday night hadn't made me feel that our relationship was close to moving beyond friends-with-benefits.

* * * *

Early Saturday morning, I pulled into a spot next to Summer's car. We were at a neighborhood park close to my apartment. We both got out of our cars and exchanged Good Morning's. The park had a big cement path around its edges, and Summer and I joined the several walkers on it.

"Thanks for coming. I wanted to talk before tonight."

"Okay."

"First off, I had another good week. Bunco was less exhausting and more fun."

"Was Wednesday still a bad day?"

"Sadly, it was. It was the day I visited with Becky and Steve cheated on me. Steve paid the bills, so I never looked at our credit card statements. After I filed for divorce, I got a copy of our statements, and there were charges at a restaurant every Wednesday for months before you saw him."

Before Becky saw him. I felt bad for a moment about having lied to Summer about that.

"On Wednesdays," said Summer, "I spend the evening curled up on the couch under a blanket. Being with Becky reminds me of Steve, but I don't feel like doing anything outside of the apartment. Or do anything period."

"I'm sorry to hear that."

"It's okay. I'm making progress. And that's what I wanted to talk to you about. First off, Sunday night was great. It really lifted my spirits. To explain why, I have to admit that I asked Kevin to suggest to you that you ask me to be your girlfriend. I was surprised when you said you wouldn't, but I loved your reasons for why you wouldn't. It makes me trust you so much more. And it also made Sunday night so special. So many times, I've heard women say that their boyfriend or husband is their best friend. I never experienced that with Steve. I got to experience that some Sunday, and that filled needs that I didn't know I had."

Summer and I were walking briskly now and passed a middle-aged woman who was walking her dog.

"I asked you here to do two things for me," said Summer. "I'm happy that Kevin and Becky are a couple. Still, it tears me up some to see them holding hands, hugging, or kissing. I miss doing that with Steve. They aren't excessively affectionate, and I think it's good for their relationship to be affectionate. So, after we had such a good time Sunday night, I started thinking about us being physically affectionate like they are. It would be us expressing our warm friendship for each other."

"Seriously?" I had never heard of anything like this.

"Yes. We wouldn't do it when it's just you, me, and Becky. But we would do it when it's just you and me and when it's all four of us. And let's be honest, Becky and Kevin's relationship is still less than rock solid. I think if we were physically affectionate in front of them that would encourage them to be more physically affectionate."

"What exactly are you talking about? Holding hands when we're sitting together?"

"Yes. Hugs and kisses when we say hello and goodbye. Only in the apartment - I'm not into public affection."

"Okay." I thought that over. I felt like someone was offering to give me a thousand dollars. What were the strings that were attached? I didn't see any. "I could do that." I decided I needed to be more positive than that. "I'd like to do that."

"Great."

"Do you want me to buy you a dress to wear to dinner Saturday?"

"No. Absolutely not. I don't like drawing attention to myself in public. I'd feel very uncomfortable wearing a dress like Becky has worn."

"Okay." That was a relief.

"I think something that also made Sunday night so great for me was Saturday night. Being affectionate with Kevin fulfilled my biggest needs. He's so much like an upgraded version of Steve. So, after having my biggest needs fulfilled, I was more aware of my other needs that you fulfilled on Sunday night."

I felt queasy. I didn't like to think about Saturday night. What Summer and Kevin did was wrong. What Becky and I did was wrong.

"I asked Becky if we could do Saturday and Sunday nights like last weekend, and she turned me down. She wants tonight and tomorrow night to be like Sunday night. If you could convince her to do it tonight like last Saturday, I'd greatly appreciate it."

Suddenly, I saw the strings.

"I...um...if it comes up, I'll see what I can do."

"Thanks."

We were coming back around to our cars. Summer said, "I should let you get to sleep." We closed the distance to our cars, and Summer veered off to her car. No hug or kiss goodbye this time. "See you in a few hours," she said.

"See you then."

* * * *

Later that afternoon, I woke up to Becky, Summer and Kevin bringing the furniture Summer wanted to sell into my apartment. Summer greeted me with a small kiss, and then the four of us loaded up my Xbox, my PC, and several pieces of my furniture into the moving truck. Becky had rented the truck, and she and I rode over in it to her and Summer's apartment.

"Kevin gave me another dress last night," said Becky.

"Another sexy one?"

"Yes. And he slept with me last night. But we just slept."

"Just slept?" I asked lightly.

"Well, we did more than sleep, but we didn't make love. I'm not ready for that yet."

"Okay."

"He called me Thursday and asked if he could spend Sunday night at our apartment and work remotely Monday. I agreed to that."

"So you're getting along better?"

"Yes, but we've still got far to go. He didn't want me to drive the truck, but he didn't want me to drive his Mercedes. And then he wanted Summer to drive the truck so I could ride with him in his Mercedes." Becky shook her head. "He drives me crazy at times."

I chuckled. "I can believe that."

"Summer asked me if we could do tonight like we did last Saturday. I told her no..."

Here was my opportunity to do what Summer had asked me to do. "And you're having second thoughts about that?"

"Last night, Kevin and I did quite a bit in my bed, and then, this morning as soon as Summer left to go for a walk with you, Kevin was all over me. And Summer was quite adamant that another Saturday night with Kevin would help her keep making progress."

Becky sounded like she was on the edge, and that I could easily push her off one way or another. Did I want to make out again with my sister? It was wrong. It was absolutely wrong.

"I think Summer has made enough progress to know what helps her and what doesn't. It's great to see how much happier she is now. I'm for tonight being like last Saturday."

"Okay. I'll let her know."

Becky and I chatted about usual stuff until we got to her apartment. The four of us got my stuff into the apartment and put everything away, and then Becky drove the truck back. Becky and Summer had assigned me a corner for my PC desk. Once I had it set up, I could barely roll my chair back far enough to get into it, but I felt that I had enough space to use my computer. Summer and I divvied up the closet and dresser space so that both of us were able to get all of our clothes put away. So far, so good on moving in.

After Becky came back, she changed into the new dress. She looked stunning when she came out of her bedroom. The dress was sky blue with a plunging neckline that showed a lot of boobflesh. I couldn't see how she could be wearing a bra.

Kevin showered Becky with compliments, and she ate them up. Again, he had me take pictures of him and her. Kevin drove us in his Mercedes to the restaurant, where I again took pictures of him and Becky. And then, to my surprise, Kevin asked a stranger to take a picture of all four of us. Kevin moved us so that he was in between Summer and Becky and I was on the other side of Summer. Kevin had both of his women next to him. We smiled as the person took a couple of pictures after which Kevin thanked him. Part of my smile was from the fact that I'd be getting lots of "benefits" from Kevin's women either tonight or tomorrow night.

When we got to our booth, Summer indicated that I should get in first. I was seated across from Becky and thought she looked beautiful. "You look great tonight."

"Thank you."

Over dinner, Becky talked to me a lot, and Summer talked to Kevin a lot. It felt like Becky was my date more than Kevin's, despite that Kevin and Becky held hands a lot.

Back in the apartment, Becky changed into sweatpants and a T-shirt but no bra while Summer picked out the movie. Becky turned out the lights and joined me on the couch. We held hands while we watched the movie, and Kevin and Summer did the same.

Once the final credits started, Summer and Kevin were kissing. I turned off the TV and turned to kiss Becky. She was ready and eager to kiss. Ten minutes later, Summer lost her top. Twenty minutes later, Becky lost hers. No holding back tonight. It was so hot and crazy with Becky. I'd do similar things tomorrow with Summer, but my heart didn't pound in my chest when I was with Summer like it did with Becky.

The action between Becky and me steadily ramped up. While she straddled my lap and had me suck on her tits and squeeze her ass, I checked on Kevin and Summer - Summer was giving Kevin a blowjob. I guessed that once Kevin came, he and Summer would adjourn for the night. I moved my face to between Becky's tits, puckered my lips, and then wiggled my face as fast I could, smearing saliva all over Becky's tits. She laughed.

"You nimrod!"

"But you love your nimrod, don't you."

Becky looked at me seriously. "I do love my nimrod." She kissed me gently.

We were kissing gently like that when Kevin announced, "Summer and I are going to bed."

Becky turned and waved goodbye to them before slipping off my lap and nodding her head in the direction of her bedroom. We got off the couch and walked hand-in-hand into her bedroom. Becky had me look away while she changed into a nightshirt. We then got into her bed with my head on her chest by her shoulder.

"I'm glad you're not driving back to your apartment tonight," said Becky.

"I am too." I added, "You looked great tonight. Kevin gave you lots of compliments, and I second all of them. Dressing up nice like that really suits you."

"Thanks." After a pause, "I think I know what Summer's plan is."

"What is it?" I was curious.

"Let's be honest. Summer is head over heels in love with Kevin. They're probably fucking right now. He's replaced Steve in her life. So I'm thinking Summer is planning on moving out and into an apartment with Kevin. By inviting you to live with us, she's setting it up so I won't have an empty bedroom to pay for. So, whatever hassle it is sharing a bedroom with Summer, keep in mind that it's probably just temporary. Would you be fine living with only me?"

"Yeah. Definitely."

Would Becky and I have nights like tonight if Summer moved out? I doubted it. With Kevin and Summer making out on the next couch, it was natural for Becky and I to make out. I couldn't see us choosing to make out if it was just the two of us. We both knew it'd be wrong to do, and we wouldn't get past that sense of wrongness by ourselves.

"So you're dating Kevin even though you know Summer is head over heels for him? And he seems equally enamored of her?"

"Yes. Dating Kevin was a lot of fun tonight. It surprised me how much I enjoyed the date. I loved him buying me an expensive dress and then oohing and aahing when I wore it. I enjoyed getting all dolled up for him and him telling me how great I looked. I enjoyed riding in his fancy car. It gave me a thrill when he put his arm around me for pictures in front of the restaurant."

I was filled with envy. I knew I'd never do that with a girl. It wasn't me. If Summer became my girlfriend, I'd never do it with her - it wasn't her.

"But after we ordered our food," said Becky. "Summer reeled Kevin back. She let him have fun with me for a while, but then it was time to be with her."

"And now, they're probably fucking."

"And I'm fine with that. I had a great time after the movie, better than if I had been with Kevin."

"I had a great time too." I turned, moved up to kiss Becky, and then went back to my spot. "Kevin can be such a manly, macho ass at times, so I have to admit that being with you was made sweeter by knowing that I was sucking on his date's tits right in front of him. I felt like I was cutting him down to size."

Becky laughed. A few moments later, she asked nervously, "Were you...good with what we did tonight? Did you want to do more?"

"No. I'm fine with whatever you want to do."

"I'm thinking about freezing things for both you and Kevin. The next step for Kevin and me is to make love. And that would be fun, we're consenting adults, I'm on birth control, and all that bullshit. But he's in love with Summer and not me. She's the one he should be making love to. And...I don't want to do the next step with you as I think I shouldn't give my brother a blowjob. That's sex. That's incest. It's a line I don't think we should cross."

"Okay." I thought about pointing out that Kevin and Summer didn't seem to have any problem crossing that line, but decided against it. We had to make our own decisions. The old 'If someone jumped off a bridge, would you jump too?' line came to mind.

A thought came to me. "Do you think that tomorrow night, we should pair up like we did tonight instead of you being with Kevin and me with Summer?"

"I don't think so. I'd be fine with that if tomorrow night Summer declared that she and Kevin are in love and want to be together, but I don't think she's ready to do that. That would be a huge step; to declare that you're in love with your sibling. She may not have admitted it to herself yet. I think she's more comfortable pretending that they are only close siblings and that she only needs Saturday night with him. And you enjoy being with Summer, don't you?"

"Yes."

"You should be with her and not your sister. So have fun with her unless she declares she wants to be with Kevin."

"Okay." I felt disappointed but knew I shouldn't be. Summer was gorgeous. Summer was not related to me. But Summer was only a friend and didn't make my blood boil.

"Long day," said Becky.

"It was."

"But I am not sleepy. My heart is still pounding. Could we do some slow kissing? Nothing exciting? Something to bide the time until I'm sleepy?"

I moved off her shoulder so Becky could move to face me. "I'm your huckleberry."

* * * *

Sunday was nice. Summer and I spent the time before dinner sitting on the couch holding hands and talking, while Becky and Kevin did the same thing on the other couch. Becky let Kevin pick the movie, so we watched a Marvel movie.

After the movie, I started making out with Summer. This time, I watched for how interested Summer was in what Kevin and Becky were doing. And she did regularly check on them. Kevin was making out with Becky enthusiastically. Summer was not as enthusiastic with me, but I didn't expect her to be - she was my friend-with-benefits. It was fun and relaxed with her, and we progressed slowly. I hoped for a blowjob, but no such luck. Kevin got a blowjob and ate out Becky, and then they headed off to Becky's bedroom to go to sleep. Summer went to her bedroom at the same time, leaving me with a painful hard-on. I gave everyone some time to go to sleep before jerking off to porn.

* * * *

As Summer had predicted, living with Becky and Summer wasn't much different than living by myself. I'd see them for ten to twenty minutes in the morning and for fifteen to forty-five minutes in the evening. Becky was usually the first to leave for work and the last to get home. I wasn't a messy person and tried to adjust myself to Becky and Summer's level of cleanliness. Tuesday night became cleaning night with all three of us pitching in. The girls told me what to clean, and I cleaned it.

For the next two weekends, we ran back what we had done the weekend of my moving in. Friday night, Kevin would give Becky a new sexy dress. Saturday morning, Summer and I would meet somewhere for a walk. A hike actually, as Summer preferred something more vigorous than walking and I had found a park not too far away with hiking trails. Saturday night, Becky would get all dressed up, and the four of us would go out to eat. Kevin insisted on paying for dinner, saying that I'd be picking up bagels. Saturday night after dinner was sibling's night. Summer and Kevin did oral sex on each other; Becky and I didn't. Sunday night was couple's night. Becky and Kevin did oral sex on each other. Summer and I didn't.

I began to doubt Becky being right about Summer and Kevin. Summer was growing more enthusiastic in our Sunday sessions and was paying less attention to Kevin and Becky. She seemed happy that Becky and Kevin were a couple. I didn't see any signs that Summer was about to announce that she would be moving out into an apartment with Kevin. When Becky had told me that Summer was head over heels for Kevin, I had stopped updating my document on Summer. Now, I had resumed working on it. I was starting to have glimmers of hope that Summer might be my girlfriend someday.

The next weekend was going much the same. Saturday morning, Summer and I were hiking. We were well back into the park and were at a spot that had some rocks that could be sat on. I said, "Let's sit for a while."

"Okay."

I took Summer's hand. As we were alone, I hoped she wouldn't mind. She then squeezed mine, reassuring me.

"I'd like to talk about us," I began. "Or more correctly, about you and Kevin. The night after Becky's second date with Kevin, she told me that she thought you were head over heels in love with him. Are you?"
Summer sighed. "Fair enough. Before I answer that, let me give you some background."

"Okay."

"When you walked out of the room after telling me that you had seen Steve with a woman at a restaurant, I couldn't think. I was just overwhelmed. I went and talked with Becky, and she told me what to do. I did what she said, and Steve confessed to cheating on me. My mind shut down at that point other than telling me to call Kevin. Kevin and Becky did all my thinking for me for a while. When I did try to think, my thoughts were 'Why did Steve feel he had to be with another woman when he had me?' and 'What had I done wrong that led to my marriage failing?' It was not pleasant to think then."

I stood up, moved to Summer, and wrapped her up in a hug. "I'm so sorry, Summer." I held her tight for a while.

Summer pulled back with tears in her eyes. "You have nothing to feel sorry for. It was horrible, but it was all for the best. A month before that, I had talked to Steve about starting a family. We agreed that we needed to get in a better place financially before having kids. So, I'm very glad to have found out about Steve cheating on me before we had kids." She waved her hand in a no-more gesture. "When Kevin and Becky went on their first date, I was still not thinking clearly. I was totally surprised when you told me that if Becky hit it off with Kevin like I thought she would, Kevin would cut me off to be with her. It made total sense, but I hadn't considered it. And it totally shocked me. I didn't want that to happen. I needed Kevin. I needed his love and his strength. I wanted to cuddle and kiss with Kevin for the rest of my life. Again, I wasn't thinking clearly at this time. I was just reacting, and my reaction was that I needed to take Kevin away from Becky so he'd be there to support me."

"Wow!"

"So when I came back from the bathroom, I had you moved over so I'd be across from Kevin. And I started working on taking Kevin away from Becky. Kevin is vain, and I fed his ego for the rest of dinner. Once the movie was over, I made my move on Kevin. I kissed him and kept kissing him. When I pushed my tongue into his mouth, he responded as I hoped. Again, I wasn't thinking. I let my feelings for Kevin go, and we were soon making out like crazy. Yes, I was a total shit to my best friend, but it didn't matter as I was head over heels in love with Kevin. I convinced him to tell Becky that he was spending the night with me. I was floating on a cloud when we walked into my bedroom."

"Did you make love that night?"

"No. Good thing. When we went into my bedroom, I wanted to. I told Kevin that I loved him and that I wanted him in my life forever. I wanted him to dump Becky and be solely with me. But then Kevin dumped cold water on everything. He pointed out that he had just told our parents that Becky was now his girlfriend. Him dumping Becky the next day would raise all sorts of red flags. And Becky would also probably tell him to stop coming to visit. The only way he could be solely with me was for me to quit my job and move in with him. Again, that would raise too many red flags. I realized that I had screwed up, that I had acted without thinking, and now I was in danger of ruining everything. Kevin said that we'd have to wait for a while before we could be together. We'd have to plan everything out before we made any moves to do that. In the meantime, we'd have to patch things up with Becky. In the morning, he'd apologize to her and hope that she'd forgive him. I suggested that he propose that Saturday and Sunday nights go back to how they had initially been - me starting with Kevin and then switching to you. But Kevin didn't think he could get Becky to take him back unless he promised to be completely hers all day Sunday."

"And she barely took him back with that."

"Yeah. I wasn't thinking clearly at all then. I told Kevin to tell you that you should ask me to be your girlfriend. I thought if Kevin was dating Becky, I should be dating you. He was dubious but agreed. I think he didn't want to keep telling me no. But it was a bad idea, and thankfully you rejected it. By that time, I was out of the mood to make love. I was too worried about Becky rejecting Kevin's apology and saying that she didn't want him to visit again."

"All right."

"So coming into Sunday night, I was head over heels in love with Kevin. Over the day, I came up with the plan that I would get you and Becky to make out and have sex, and then Kevin and I could suggest that you two become a permanent couple and we become a permanent couple."

"That's a crazy plan."

"I know. And then that night, Kevin made out with Becky much like he made out with me. That shocked me. I thought he'd be with Becky like I was with you. I had fun being with you, but it was having fun and not expressing my love like it was with Kevin."

I squeezed Summer's hand. "It was fun for me too."

"Tuesday at Ikea, I jumped at the opportunity to have you move in with us. That would mean more time for you and Becky to fall in love."

"Again, another crazy plan."

"Yeah. I was all emotions at the time. I may have suggested it for the wrong reasons, but it has worked out well. I like you living with us."

"Thanks."

"The good thing about this time was that I finally had hope again. I felt desirable again. I started coming out of my depression. The planning was clearing out the cobwebs in my head. I was thinking more clearly. On Kevin's second date with Becky, I realized that he needed to date Becky; that he needed to have a girlfriend to boast about. He would never be able to boast about me. And those boasts would quickly turn hollow for him if he didn't have some kind of sex with Becky. And then the next night as he was as enthusiastic with Becky as he had been with me, I realized he wanted to fuck us both. Yes, he loved me, but the idea of having two women greatly appealed to his ego. And again, he needs to be able to brag about fucking someone."

"Geez."

"So I stopped being head over heels in love with Kevin. Do I love him? Yes. He's everything that Steve was and a whole lot more, and I married Steve. Do I think I can make a relationship work with him? I'm not sure. I think a lot about telling him to be exclusive with Becky. He and Becky can have a life together much more than he and I can. But I'm not ready to give Kevin up yet, so my plan now is to keep doing what we've been doing. Are you enjoying being with Becky?"

I didn't want to discuss my relationship with Becky, but after Summer was so honest with me, I felt I needed to reciprocate. "Yes. Very much. I prefer Saturday nights to Sunday nights."

"Are you thinking about going long-term?"

"No. We're content to keep doing as we've been doing. Are you and Kevin fucking?"

"No. I don't want to make love until I think I can make a relationship work with him. Are he and Becky fucking?"

"I don't think so."

"Could you find out for sure for me, please? It would mean a lot to me." When I hesitated, Summer added. "You can tell her everything I've told you before you ask her."

"I'll ask. No promises."

"I can't ask for more than that." Summer stood up and pulled me into a hug. "You're the sweetest guy I've ever known. I'm so glad you're in my life." She kissed me.

"I'm glad you're in my life."

Summer turned and took a step. "Ready to hike back to the car?"

"Sure."

* * * *

After my talk with Summer, I had more hope that she'd eventually become my girlfriend; that things would blow up with Kevin or Kevin and Becky would decide that they were now in love enough that they wanted to be exclusive. And then I'd be there to help her get over Kevin.

Consequently, I felt less and less willing to risk what I already had. I was already getting most of the benefits of having a girlfriend except for sex. And I was getting hot fun with Becky on top of that. Should I ask Summer to start giving me blowjobs? My nudges hadn't gotten her to do anything, and I suspected asking her outright would fail. Apparently, 'friends with benefits' with Summer didn't include oral sex as a benefit. For the time being, jacking off to porn after everyone was asleep would have to satisfy me. I had always liked MFF videos, and now that was all I'd watch, imagining it was Becky and Summer with me.

The next Saturday, Becky and I were on the couch after Kevin and Summer had gone to bed. What Becky and I had been doing lately was to start slowing down when Kevin went down on Summer. We knew that it wouldn't be too long after that until Kevin and Summer went to bed, and we would follow shortly thereafter. In bed, Becky and I would talk for a bit, kiss gently for a bit, and then we'd cuddle up and she'd drift off to sleep. But tonight, Becky had kept up the hot action until Kevin announced that he and Summer were going to bed.

Becky and I waved to Summer and Kevin as they walked hand-in-hand to Summer's bedroom. Once their door was closed, I pounced on Becky's tits, sucking on one as I squeezed the other. As I feasted on her tits, Becky slowly slid across the couch while slowly leaning back until her back was against the armrest. She had one leg along the back of the couch, the other on the floor, her arms wrapped around me, and her hands cradling my head as I licked circles around her nipples.

"Big Sister loves this. Keep it up."

After I had attacked her tits for a while, Becky counterattacked, pulling my head up into a passionate kiss and making me lean back. I put one hand on the couch to keep my balance and put my other down on her ass. When I squeezed Becky's ass, she shifted into a kneeling position and kissed me more frantically.

I couldn't help wondering if Becky and I were going to give in to our passion for each other. If Becky peeled off her panties, I knew I'd fuck her. I'd fuck her and absolutely love it, as wrong as it was.

Becky suddenly pulled back. She nodded her head in the direction of Summer's bedroom. "Do you think they'll fuck tonight?"

"I doubt it." I'd rather think about Becky and I fucking. "Did she give you any indication this week that they'd fuck?"

"No. But I did tell her yesterday that I thought it was unfair that she wasn't taking care of this." Becky put her hand on my cock, much to my shock and surprise. "Kevin is getting taken care of by both her and me, and no one is taking care of you."

Becky rubbed her hand up and down my cock through my jeans. It felt fantastic. I was so hard.

"What did she say?" I asked.

"That she was doing with you what she was comfortable doing and that you seemed to enjoy it. Are you going to ask her to be your girlfriend?"

"No." My cock was straining against my jeans. It was leaping up against Becky's hand every time she started a stroke.

"How come?"

"Because once she feels up to dating, she would dump me and start dating the type of guy she likes. Do you think she's getting close to declaring she's over Steve?"

"Wednesdays are still bad days for her. Otherwise, I think she is."

I was afraid I might come in my pants. "So, Summer and I are going to remain 'friends with benefits', and blowjobs aren't one of the benefits." It was hard to dispassionately talk about Summer with Becky rubbing my cock.

"It's not fair. You must be in pain tonight."

I had no idea where this was going, but I wanted to keep it going. "He's uncomfortable."

Becky stroked my cock again. "I think he'd be more comfortable if you took off those jeans."

I reached for my zipper. "No doubt." I unzipped my jeans and pulled them down to my ankles.

"Summer should be taking care of him," said Becky as she stroked my cock through my underwear. She then slipped her hand under the waistband and gripped my cock. "Pull down your underwear."

I pulled down my underwear to my jeans.

"He's so big and hard," cooed Becky. "He definitely needs someone to take care of him." She slid her fingers gently up and down my cock's length. "Would you like Big Sister to take care of this problem?"

"I would love Big Sister to take care of this problem."

"Would you like a handjob or a blowjob?"

I thought back to Becky saying that we wouldn't do oral sex with each other because that was incest. "Blowjob." Frankly, I didn't care if this was incest.

"That would make things more fair. I want to get a little more comfortable before I do that."

Becky slipped off her shorts and then knelt on the couch while keeping a hold of my cock. She leaned forward until she slid her mouth down my shaft. I moaned. She slid her mouth back up and said, "That sounded like someone in need of relief."

I guessed that Becky was justifying giving me a blowjob by saying that, as my big sister, she needed to give me relief. I decided to encourage that train of thought. "I'm badly in need of relief."

Becky made a circle with her hand and slid it from the wet portion of my shaft to the dry portion to get it all wet. "I'm going to give you a basic blowjob. Just something to give you relief."

"I'm good with that."

Becky took my cock back into her mouth and started slowly bobbing up and down on it. I put my hand on her naked back and began rubbing gently in circles to encourage her. Becky's tits were hanging down enticingly.

"Try to come as quickly as you can," said Becky as she took a break from bobbing on my cock. "Summer should be the one doing this."

"You're right. She should be." But if given a choice, I'd prefer Becky to be the one doing it. Being with Becky was so much hotter than being with Summer.

Becky ran her hand up and down my cock and then took it back into her mouth and resumed bobbing up and down on it.

I watched Becky's head action for a while before looking down her body to her panty-covered ass. I realized that she had taken off her shorts for a reason. I slid my hand down her back while leaning toward her ass until I had an ass cheek cupped in my hand. I checked to see how Becky responded to my hand. She didn't do anything other than continue bobbing her head up and down. I gave her ass a squeeze through her cotton panties. No reaction. I was not too surprised as I had squeezed Becky's ass numerous times just a little while ago, but that was always through her sweatpants.

"Enjoying yourself?" said Becky as she took a break.

"This is wonderful," I said. When she had first stopped, I felt like a kid caught with his hand in the cookie jar, but then Becky didn't say anything about me squeezing her ass. I gave her ass another squeeze. "You're the best big sister."

"Someone has to look after you."

Becky dived back onto my cock. I gave her ass another squeeze. And then I wondered - why not?

I slipped my hand under the waistband of Becky's panties and kept sliding it forward until I had cupped her bare ass in my hand. Becky bobbed her head up and down even faster. God, her butt felt so good in my hand. I squeezed her bare ass, and that push me over the edge. I started coming, spurting big jets into my sister's mouth. She stopped bobbing and instead sucked my cum down. I shot more and more cum into her mouth, and she took it all.

When I was done coming, I pulled my hand out of Becky's panties. "Thanks."

"You're welcome. Now, let's go to bed."

We walked to Becky's bedroom, brushed our teeth in her bathroom, and got into bed. There, we alternated kissing and talking. After a while, she pushed my head against her chest. I stayed there quietly until she drifted off. I then got up and left the room.

* * * *

The next Saturday as everyone was placing their drink order, Summer asked me, "Why not try a beer?"

"Why not?" I asked the waiter, "What beers do you have?" He went through their list, and I picked one that was on my list of recommended beer brands.

After the waiter left, Kevin said, "Color me surprised."

I shrugged and looked at Summer. "I stopped drinking because of one girlfriend. It's not surprising that I'd start back because of another girlfriend." I smiled. "Or near girlfriend."

"Mid-girlfriend?" replied Summer. "Midway between a girlfriend and a friend."

"I like that."

I took Summer's hand under the table and squeezed it. Every week, I felt closer and more comfortable with Summer. But every week, I felt closer and more comfortable with Becky. And I hadn't gotten any signs from Summer that she wanted to be anything more than my mid-girlfriend.

* * * *

That night after Kevin and Summer had gone to sleep, Becky and I remained on the couch. She rubbed my cock through my jeans and asked, "Need relief again tonight?"

"I do." I took off my jeans. Becky took off her shorts and was down to her panties again. "Would you prefer to do this in your bedroom?"

"I'm not worried about Kevin catching us. He does much more with Summer. I know that Summer told you that they aren't fucking, but I suspect they will succumb to temptation at some point."

"Will you and Kevin fuck soon?"

Becky thought for a moment. "I don't know. I know he loves Summer and not me, but I feel that he does care for me. Maybe someday we'll succumb to temptation."

"After you do me, do you want me to do you?"

"No. I don't need sexual relief. You do. Summer should be the one to give it to you, but I'll step up because she won't."

"Okay."

Becky gave me another great blowjob while I squeezed her ass under her panties. If Summer was my mid-girlfriend, what was Becky?

* * * *

Sunday night, I was kissing Summer after the movie again. It was great, but, at the same time, it felt so tame. This was dog bites man. Saturday night was man bites dog.

Summer gave me her I'm-ready-for-the-next-step smile and started removing her blouse. Soon, I'd be sucking on her glorious tits. I looked over, and Kevin was already sucking on Becky's tits. Did Kevin feel the same as me? Was sucking on Becky's tits a delight, but paled in comparison to sucking on Summer's tits?

I was holding Summer's hand now, and we were talking. We were in our cycle of talking, then kissing, and then my sucking on her tits. Kevin was eating out Becky. I wished I could do that. I wished I could make my sister squirm in pleasure until she came on my face. But not yet.

Leaning forward, I kissed Summer. In each cycle, we would ramp up anew. We started with gentle kisses, kissed more passionately, Frenched, I'd squeeze her tits while we Frenched, I'd switch to sucking on her tits, and then we'd take a break and talk again. As we kissed, I thought about Kevin eating out Summer. It was wrong, but it was so hot to watch. It was like a porn video where half-siblings have sex but in real life. I felt my passion rising with Summer, not because of us kissing, but because I was thinking of her and Kevin. How much longer until they succumbed to temptation? I felt like they were the most likely to take the next step forward. Would they fuck in front of Becky and me? That would be so hot.

I pushed my tongue into Summer's mouth and reached for her tit. Thinking about her and Kevin fucking was getting me very hot. I'd come hard when I watched porn tonight. What if Kevin got Summer pregnant? What would they do? Kevin wanted to be a dad. Would Summer move in with Kevin? Would they secretly get married?

God, I wished Summer would give me a blowjob, but I knew that wasn't going to happen. Even more, I wished Becky would sneak in another blowjob. I'd love it if she tucked Kevin into bed, came out, gave me a blowjob, and went back to bed. But I knew it would be just me and my hand tonight.

* * * *

Tuesday afternoon, Summer surprised me by coming home at four. "Would you do me a favor, Matt? Would you call the cable company for me, please? The cable service in Steve's apartment is in my name, and every time I've tried to cancel it, I haven't been able to. The first time, I wasn't prepared for how long I had to be on hold. The second time when I got to someone, they wanted me to talk to someone else before canceling the service, and I wasn't prepared for that much time. And of course, I can only call them during business hours when I should be doing work. And on top of it all, I know I'll have to get the cable company's equipment from Steve, and I'm dreading doing that. Would you do it all for me, please? Including getting the equipment from Steve? Please, please, please?"
I smiled at how desperately Summer wanted me to handle this. "Sure."

Summer whipped out her phone. "Let me text my lawyer to arrange with Steve's lawyer you're coming over to pick up the cable equipment." She punched away for a while. "Done. Let me call the cable company." She called the number and handed me her phone. I put her phone on speaker while I played a game on my phone. Wait times are longer than normal because of unusually high call volume. What utter bullshit. Wait times were long to discourage people from canceling their cable service.

I finally got to someone, and I explained that I was canceling Summer's cable service. Summer got on to say that she was Summer, and she approved of me acting for her. That got us put into another phone queue. I finally was connected to a Retention Specialist who started offering deal after deal to try to convince me to not cancel the Service. I patiently turned each of them down. "No, I don't want Disney Plus for free for three months." Another long wait in a phone queue, and then, after much jumping through hoops, the cable service was provisionally canceled.

"You will continue to be billed for the service until we've received our equipment back," said the representative.

"Understood."

When I hung up, Summer gave me a big hug. "Thank you! Thank you! Thank you!"

"No problem. You got a text while I was on the phone." I handed her back her phone.

"Oh! My lawyer said that Steve will be home at seven tonight for you to pick up the equipment." Summer looked at me anxiously. "You're okay with doing that?"

"Sure."

"Don't get in a fight with him."

I smiled. "I won't."

"I know Kevin would."

I shook my head. "Look. Every day, I deal with people who are scared and anxious. I get them to calm down, to get into the proper position, and then go into this big, scary machine and not move for a long time. I can handle dealing with Steve."

"Okay. I'll start making dinner."

At seven on the dot, I knocked on the door to Summer's old apartment. Steve opened the door and said, "Come in." Steve didn't recognize me at first. "You're..."

"Becky's little brother. She occasionally sticks me with running her errands for her." I had decided to pretend that I wasn't close to either Summer or Becky.

I looked around the apartment. It was no longer the neat apartment it had been when I had helped Summer move out. Now, bags, papers, and bottles were everywhere. The floor looked like it hadn't been vacuumed since I was here.

"Nice apartment," I said. "Much better than the little studio I'm in. Beautiful complex."

"Thanks. I wanted to give Summer the best place to live in. How is she doing?"

"Becky didn't say. Just told me to come here at seven to get the cable equipment."

"When the question of the cable service first came up, I offered to have Summer come over, we get on the phone together with the cable company, and I'd tell them to put the service in my name. But she refused. She didn't want to come here."

"That was nice of you," I said as I walked over to the TV. "Would have saved me a trip over here." What would have been truly nice of him was to have pulled the cable gear and had it waiting in a box for me.

"She's been so unreasonable this whole time," continued Steve. "Refusing to meet with me to discuss things. Refusing to do counseling. I want to stay married. I apologized for what I did."

"Women are as women are."

"Hopefully, she'll come to her senses."

I found the box. I had looked up what it looked like before I came over. It was in a low, wide entertainment center on the bottom.

I said, "She might. You never know about women," as I lay down on the floor.

"Want a beer?"

"Sure."

Steve went and got us a beer each while I sat up. As he handed me my beer, he asked, "What do you do?"

"Imaging tech for a downtown hospital. I work from seven pm to seven am four nights a week."

"That's right! You went to a special school in Florida for a while."

"I did."

"Wow. Working those hours must be rough."

"It's when I can get work. With shift differential, the pay is pretty decent. Remind me what you do?"

Steve told me about his job. Or more correctly, bragged to me about his job. I did my best to act impressed. And then he got to his car, a BMW.

"Does it have a manual transmission?" I asked.

"Of course."

"I don't know how to drive stick."

"You should. Every man should know how to drive stick. You don't really drive unless you're driving stick. Want another beer?"

"Sure."

Steve was so like Kevin. Having spent so much time with Kevin, I knew how to play into him and win his confidence.

"The only reason Summer and I haven't gotten back together is Becky," said Steve after he finished his second beer. "She's the one who turned Summer against me." And your cheating on her didn't? "Becky doesn't want to see Summer happily married to a guy because she can't keep a boyfriend. I think the longest she's had a boyfriend in the years I've known her is three months."

Sadly, that matched my recollection. I polished off my second beer, set it on the coffee table, and said, "Yeah, her boyfriends don't last." I turned back to the cable box.

"She's probably bisexual but prefers women. Dates guys when she's in the mood for a fuck, but drops them when she's had her fill."

My first reaction was to turn and tell Steve he was crazy, but I stopped myself. I said casually, "I've never seen anything to indicate that my sister isn't straight."

I couldn't pull the box all the way out of the entertainment center. I reached behind it and started unscrewing the cables that were connected to it.

"You're family. She probably wants to keep the fact that she's bi a secret from you and the rest of her family."

"Could be," I said while resisting the temptation to roll my eyes.

"I don't know how she is with you, but with me, she's a real ballbuster. I don't think she can handle real men. I work with a couple of women like that. Ballbusters who keep secret that they are batting for the other team. Do you know any women like that?"

"I work at a hospital. We have every type of dysfunctional person working there." Steve chuckled. "I just keep my head down and do my job."

"Smart. Say anything, and HR will walk you out the door so fast you're head will spin."

"You got it."

Steve had been sitting on the couch while we drank our beers. Now, he came over to me, knelt, and said, "I'm sure Becky and Summer are more than friends, if you get my drift."

Does this asshole really think that Becky and Summer have been lovers for years? "I find that hard to believe."

"It's not. They're thick as thieves. Summer had to spend every Wednesday with Becky. I don't think that was to discuss the latest celebrity gossip."

My understanding was that Summer spending Wednesdays with Becky was an agreed-on thing - Steve would have an evening that he could work as late as he needed, and Summer would get to spend time with her long-time best friend. Was Steve misremembering that?

"Were you okay with Summer spending Wednesdays with Becky?"

"Yeah. Even after I started suspecting that she and Becky were more than friends. I hoped that Summer would come out and admit it. I gave her a couple of hints of what I suspected, but she ignored those. I would have been fine with Summer spending one Wednesday over at Becky's and then the next Wednesday, Becky coming over here for a threesome."

This guy has watched too much porn.

"After a while," said Steve. "I arranged to have some fun of my own on Wednesdays. To keep us even. Nothing serious. Nothing long-term like what Summer had with Becky."

I had everything disconnected from the back of the cable box and pulled it out. I just needed to get the power supply and then I could head home.

"So you were open to working things out with Summer about Becky?"

"I'm still open."

I followed the power cord from the box to where the power converter was plugged in.

Steve added, "Yeah, if both of them came over for a threesome, everything would be forgiven. No more seeking out fun of my own on Wednesdays."

"Provided Becky comes over for threesomes regularly."

I set the power supply on top of the cable box and stood up.

"You got it," said Steve. "I'm a reasonable guy."

I shook Steve's hand. "You seem reasonable to me. Hopefully, you and Summer can work things out."

* * * *

Back in the apartment, I recounted to Becky and Summer my time at Steve's apartment. Summer's jaw kept dropping. Becky alternated between dropping her jaw and laughing uproariously.

When I finished, Becky said, "So Summer and I just have to go over there for a threesome, and everything will be forgiven?"

I nodded my head, "Steve's a reasonable guy." Becky burst out laughing.

Summer had a shocked look on her face. "So Steve didn't express the least regret for cheating on me?"

"He thought you were cheating on him."

Becky asked Summer, "Did he ever say anything to you about us possibly being lovers?"

Summer looked dazed. "No. Not that I remember. If anything, he encouraged me to visit you when he had to work late. He didn't want me to spend my evenings alone in the apartment, and he didn't want me going out by myself."

"It was all bullshit to justify cheating on you. If you had gone over to talk with him, he would have said all the right things. In counseling, he would have said all the right things. He would have continued to encourage you to visit me, and then used that as a justification to cheat on you again."

I said in a fake sad tone, "So no threesomes for Steve then." Becky laughed.

Summer said, "Well, maybe he can talk his current girl into a threesome. I was never going to have a threesome with him."

Becky said, "You know Kevin badly wants a threesome with you and me."

"Well, Kevin is out of luck," said Summer indignantly. "I'm only fine with him being with you when I'm with Matt. He's never going to get both of us."

"Never say never, but it'll only happen if we want to do it," said Becky. "I'm sorry to get you worked up. Let's watch a show and chill until bedtime."

* * * *

I held Summer's hand as we watched a couple of shows on TV. Summer wasn't that into them - I think she was processing all my revelations about Steve. But she seemed in a good mood when she went off to bed.

Becky got ready for bed, and I joined her. We were in our usual position for talking at bedtime with my head on her shoulder.

"I can't believe you got Steve to say all those things."

"He was a lonely guy with a non-critical audience. After a couple of beers, he was ready to tell his side of the story. In his mind, he's not the bad guy. You're the real villain."

"Which is crazy. But I'm glad you got him to say what he said and then told Summer what he said."

A concern came over me. "Was Summer thinking of getting back together with Steve?"

"He was saying all the right things through his lawyer. Once, she floated the idea that Kevin and I date exclusively, and she go back to Steve. I didn't like the idea of her going back to Steve, so I told her that I didn't want her to patch things up with Steve just so that Kevin and I could be together."

"Well, now that's never going to happen."

"I know." Becky sighed. "I kept thinking that this madness was temporary. First, it was Summer would get over Steve and Kevin would stop coming over. Then it was Summer was going to move in with Kevin. And recently, it was Summer would go back to Steve and Kevin and I would become exclusive. But now that's gone. At the same time, I know this madness isn't stable. It's going to blow up in our faces sometime. We just don't know when."

I knitted my brows. "Are you unhappy with our weekends? Do you want to stop dating Kevin?"

"No. But I know something bad is going to happen. What if Mom and Dad drop by some Sunday morning to drop something off while Kevin and Summer are still in bed? They have the keys to our apartment. They could just walk in."

"But they wouldn't. They'd let us know if they were coming over. And on Sunday mornings, they are going to church. And they always just barely make it on time as it is."

"Something bad like that will happen."

"It's possible. The most likely thing is that one of our relationships will change, and that will take us out of what has been stable. Kevin and Summer will make love. Or you and Kevin will make love. I'm sure Kevin is desperate to fuck someone soon."

Becky laughed. "We'll see. Summer seems to keep Kevin on a short leash."

"Is there something else bothering you?"

"Steve's idea of me being a secretly bisexual ballbuster actually didn't sound that crazy to me. I think several guys at work view me as a ballbuster and suspect that I'm secretly gay. As Steve said, I've not been able to keep boyfriends."

"You've been fine. You've been able to go out on dates anytime you want. It's not like your social life consists of chatting with a bunch of single dudes in Japan."

Becky snickered. "Yeah, that would absolutely suck."

I wanted to reassure Becky, so I added. "You've not been ready for a long-term relationship. You've been busy building a quite successful career. You've needed the freedom to work late when you needed to and travel when it was best. A long-term boyfriend would have shackled your career. Probably the guys at your work who view you as a secretly gay ballbuster long to be your boyfriend and are angry that you've not given them a chance."

Becky ran her fingers through my hair. "You're probably right."

"And you're dating Kevin."

"Let's be honest, the only reason Kevin is still dating me is that I let him be with Summer. Though he tells me he's very happy to have me as his girlfriend. I think part of my appeal to Kevin is that he's the man who's tamed the shrew." Becky chuckled. "Remember how you told me once that being with me was made sweeter by knowing that you were sucking on Kevin's date's tits right in front of him? When the movie ends on Saturday night, I always think, 'So Kevin, you think you have this shrew tamed. Let me show you how wrong you are.' She laughed for a bit and then sighed. "As this madness continues, the more and more I don't want it to end. I've come to love talking to you in bed. And I'm happier with Kevin than any boyfriend I can remember."

"I'm happy with how things are. I fear that if I try to change anything, it'll all come to an end. Let's just keep it going."

* * * *

Wednesday afternoon, I was awakened by the sound of someone coming into my bedroom.

"It's me," said Summer.

Oh, and it was her bedroom too. I was on my side facing away from the door. I looked at the clock. It was a little after three. "What are you doing here?"

Summer slipped into the bed. "I decided to do something different for Wednesday. I came home early from work to take a nap with you, and then I'll make up the time missed by working tonight."

"Uh..."

"Come on. Let's nap, and we'll talk later."

Summer put her hand on my stomach and encouraged me to go back onto my side. Why not? I rolled back to my side. Summer slid up next to me. My eyes went wide when I felt her bare breasts press against my back.

"Relax and nap," said Summer soothingly as she rested her elbow on my side and put her hand on my chest.

I didn't think at first I could go back to sleep with Summer's bare tits pressed into my back. But I had sucked on those tits, so this wasn't terribly new. I calmed down and then drifted off.

* * * *

When I woke up, Summer was still pressed against my back. I slid forward while twisting so that I was lying on my back.

Summer leaned forward and kissed me. "Sleep well?"

"Surprisingly well."

"That was nice." Summer moved her hand to my stomach and started rubbing it softly. "You know, Wednesday has always been my bad day. I've been thinking about doing something different. You dealing with Steve yesterday made me appreciate how much I enjoy living with you."

"And I'm the sweetest guy you've ever known," I said with a little bitterness.

"And I had an idea," said Summer ignoring me. "I decided to leave work early, come home, nap with you, have some fun with you." Summer moved her hand lower to just above my underwear. "And then I'll make up for the hours off by working remotely tonight."

"Have some fun?"

Summer slid her hand under the waistband of my underwear as she moved her lips close to mine. She said in a sultry whisper, "I so enjoy our Sundays, and I'm ready to do more."

We kissed as Summer gently stroked my cock. Would I finally get some action from Summer? I raised my butt and slid my underwear down as far as I could. Summer stroked my cock a few more times and then ended our kiss to throw the covers back. She helped me take my underwear off.

Summer laid down on top of me and pressed her pussy against my cock. She was wearing only black cotton panties. She said, "I've really been torn. I'm in love with Kevin, so it wouldn't be fair to say that I want to be your girlfriend. And I didn't want to go beyond what we were doing unless I was your girlfriend. But I want to be more than your mid-girlfriend."

Summer shifted her legs so that she was kneeling on top of me. She took my hands and brought them to her tits. I squeezed them.

"What do you want?" I asked.

Summer laughed bitterly. "I want lots of things." She lowered her head until her face was close to mine. "Do you want to hear what I really want?"

"Yes."

"I want you to fuck Becky. I want Kevin to fuck me. You and Becky on one couch, and Kevin and I on the other. I want to do it. I know all of us want to do it. Let's jump over the cliff together." Summer ground her pussy against my cock. "And the next night, I want you to fuck me while Kevin fucks Becky." Summer straightened. I kept my hands on her tits as she did. "It would be okay for you to fuck me if Kevin was fucking Becky."

"Do you really want me to fuck you?" I asked incredulously.

"Yes. Last night, remember how Becky brought up that Kevin wanted a threesome with her and me, and I said that I was only okay with him being with her if I was with you? Later when I was laying in bed, I realized that I wanted you in my life forever like I want Kevin in my life forever. You're the perfect compliment to Kevin. You make me feel loved in ways he doesn't. You make it acceptable to me for Becky to be his girlfriend. That was when I got the idea of spending Wednesday afternoons with you. That would make things even for Kevin spending Saturday mornings with Becky."

Summer dropped down so that her face was close to mine again. "Also, I miss being fucked. Steve didn't cheat on me because we didn't fuck enough. We fucked two or three times a week. I then gave it up cold turkey. I'm so ready to fuck again." Summer rubbed her pussy against my cock. "We all want it. I want you to fuck me. I want Kevin to fuck me. I want Kevin to fuck me one night, and you fuck me the next." Summer leaned back up and rotated her hips in a circle as she ground her pussy on my cock. "Is that clear enough?"

"Yes."

"Would you like that? Would you like to fuck both Becky and me regularly?"

I brought my hands behind Summer and squeezed her ass. "I'd love to fuck both you and Becky regularly. But I don't see Becky ever fucking me. Why don't you keep things simple, fuck Kevin who you love, and not worry about Becky and me?"

Summer slid off me and laid down on her side next to me. "Okay. Let me explain why only Kevin and me fucking won't work." Summer took my hand. "Kevin is a very aggressive guy. He wants to fuck Becky. He feels he should be fucking Becky because she's his girlfriend. The only reason he hasn't tried to fuck Becky is that I've told him that if he fucks her before he fucks me, I'll cut his balls off."
I chuckled.

"Kevin wants to fuck me too," said Summer. "I don't want to fuck until I'm sure our relationship will work long-term. Kevin wants to fuck now and worry about long-term tomorrow."

"That sounds like Kevin."

"Let's say that I give in on Saturday. We fuck in front of you and Becky. What will happen on Sunday?"

I quickly added two plus two. "Kevin will try to fuck Becky."

"Almost as certain as the sun rising in the East. So let's game this out. Option number one is that Becky refuses Kevin. What happens then?"

I had an inkling, but I knew Summer had better insight. "You tell me."

"Kevin is pissed. He thinks he should be fucking his girlfriend. He'll express his frustration around Becky, and Becky won't take any of his shit. They'll break up. And because Kevin is Kevin, he'll have to find a new girlfriend. Some hot chick that he can show everyone pictures of. I'm fine with Becky being his girlfriend, but anyone else is unacceptable. Kevin and I then break up."

"Okay. That makes sense. But I think Becky is most likely to agree."

"Let's say that she does. So Kevin is now fucking Becky and me in front of you, and you aren't fucking anyone. And Kevin being Kevin lets you know that he's fucking both Becky and me, and you're stuck in the Friend Zone. I think after a while, you'd decide you've had enough; that you'll go find a girl who loves you and appreciates you. You move out. And without you to counterbalance Kevin, his relationships with both Becky and me nosedive."

Summer moved back to lying on her side. "Kevin is like a big baby," she said. "Becky or I have to constantly pay attention to him. You don't need us to pay attention to you. But just because we aren't constantly paying attention to you doesn't mean we don't enjoy being with you. I understand that you don't want me to be your girlfriend because I'm in love with Kevin, but that doesn't mean I can't show you and tell you how much you mean to me. And speaking of that." Summer crawled over my leg and lay down between my legs. She grabbed my cock by its base and gave it a lick.

"Why don't you and I fuck?" I said teasingly. I hoped it sounded teasingly. Would Summer take seriously the idea of us fucking?

Summer licked all around the head of my cock like it was an ice cream cone. Looking back up at me, she said, "First off, Kevin is going to fuck me before you, just like he's going to fuck me before he fucks Becky." She took several inches of my cock into her mouth and then slowly raised her head while sucking hard. "Secondly, I'd have to be your girlfriend for you to fuck me, and I know you don't want me as your girlfriend. You've already rejected that idea."

"I'd love for you to be my girlfriend."

Summer gave my cock a lick from its base to its head. "Would you really like me to be your girlfriend? Even though I'm in love with Kevin?"

"Would you really like to be my girlfriend? Even though I prefer Saturday night with Becky to Sunday night with you?"

"Touché."

While keeping a grip on the base of my cock, Summer crawled over my legs and moved so that her knees were near my chest. She then took my cock into her mouth. As she slid her lips down my shaft, she reached back and started pulling her panties down. I grabbed her panties and helped her take them off as she continued sucking my cock.

Once she was naked, Summer moved between my legs again. She looked up at me as she slowly swallowed most of my cock and equally slowly slid her lips up my shaft. She then released my cock from her mouth while keeping a grip on the base.

Summer asked, "Seriously, do you want to be my boyfriend? You rejected me once, and I don't see why you would change your mind."

"I rejected you because I was in your Friend Zone. Now, what I hear you saying is that you're not putting limits on our relationship and are willing to see where it goes."

Summer dropped her mouth down my shaft and leisurely bobbed a couple of times. I had the feeling she was more focused on thinking than sucking my cock, but her sucking of my cock felt pretty damn good.

Suddenly, Summer released my cock and scrambled up me until she was kneeling on my crotch again. She pressed her now naked pussy directly against my cock with her pussy lips against it. She grabbed my hands and brought them to her tits. "I want to be your girlfriend." Summer started sliding her pussy up and down my cock just a little distance. "I want you in my life forever. No limits on our relationship. I want to see where it goes."

Summer lowered herself down while grabbing my wrists. She pinned them on the bed while holding her face close to mine. "And I want you to fuck me. I want you to make me scream. But you have to fuck Becky first. Promise me that you'll try to convince Becky to fuck you, and I'll be your girlfriend. All I'm asking is that you try. And you understand that Kevin will fuck me before you do."

"I promise."

Summer kissed me and kept kissing me while sliding her pussy up and down my cock. This was the most passionate she had ever kissed me. I felt my blood began to boil. It was the first time I really felt serius lust for Summer.

When she broke the kiss, Summer scrambled between my legs again and gripped my cock by the base. "Let's keep this thing from making a mess, shall we?" Summer dropped her mouth down my shaft and started bobbing on my cock.

"That feels so good," I moaned.

Summer looked up at me with a smile in her eyes. She was the best cocksucker of any girl I had dated. She alternated bobbing on my cock with licking it in different ways while regularly looking at me. She was a gorgeous woman. I felt like today was the first time she was being sexy with me, and she was very sexy when she was being sexy.

I rubbed Summer's shoulders and ran my fingers through her hair as her lips and tongue continued to work magic on me. "I'm about to come..." I warned Summer. She didn't slow down in bobbing her head up and down. I exploded, shooting spurt after spurt into her mouth. Summer sucked them all down.

When I was done coming, Summer moved back to lying on her side next to me. She kissed me and asked, "Did your girlfriend give you a good blowjob?"

"My girlfriend gave me a great one."

"Can you get a night off before Saturday so you can talk with Becky? I'd love for us to all make love on Saturday night."

"I think Becky will say no." I didn't want Summer to get her hopes up.

"Don't be so sure. Remember, I've seen you and Becky making out. She gets a lot more excited with you than she does with Kevin."

"Well..."

"And Sunday, she's in a much better mood than she's in on Saturday. On Sunday, she lets slide things she'd jump on Kevin for on Saturday." Summer rubbed her hand in a circle on my stomach. "Becky is the type who sees all the downsides to everything. She'll decide against doing something because it's too risky even though she wants to do it. She then hopes someone will talk her into doing it. That way, she's not responsible for taking the risk. And she's easy to talk into doing what she wants to do. I think you can do it."

Summer seemed too optimistic. "I don't know."

"I knew she wanted to date Kevin, but she kept seeing all the downsides. However, it was easy for me to talk her into dating him. And then she didn't want it to be siblings night on the Saturday after her first date with Kevin. Did you have any problem talking her into that?"

I thought back. "No. Not really." Then I thought of something. "She's been giving me blowjobs on Saturday night."

"Really? When?"

"After you and Kevin go to your bedroom. We stay out on the couch, and she goes down on me."

"Let me guess. She blames me for having to give you a blowjob."

I looked at Summer in amazement. "She does."

"I love Becky to death. She's been the best best-friend ever. But she's picky as hell and always holds back. She can never let herself go and be happy. I'd be fine with her blaming me the whole time she has her feet in the air with you. Try, and I think you'll be surprised at how easy she is to talk into taking the next step."

I wasn't sure, but I wasn't as negative about the idea now. It was worth trying.

I kissed Summer and said, "Time to go down on my girlfriend."

* * * *

I managed to swap shifts to get Thursday night off. Summer was the first one home as usual. "Hey, girlfriend! How you doin'?"

"Doing great," Summer said as she kissed me. "Talk with me as I change."

"Okay."

Once we got into our bedroom, Summer started removing her work clothes. She said, "I called Kevin last night and told him I'm your girlfriend."

I had a moment of anxiety. "What did he think of that?"

"He's fine with it, but he's going to fuck me Saturday night. Which I'm fine with. It's time."

Summer hung up her shirt. She was wearing a boring, peach-colored bra and somehow managed to look great in it. I still couldn't believe this gorgeous woman was now my girlfriend.

As she reached for a T-shirt, Summer asked me, "I don't think I ever asked you yesterday if you want to make love with Becky. Do you?"

"Do I want to? Yes. But I want a lot of things." I thought for a moment. "I'd say that my relationship with Becky is far more important to me than making love with her. I won't pressure her into making love. I'll say that you asked me to discuss it with her and see how she reacts."

Summer started removing her skirt. "That's sweet. I don't know if it's the right approach." She frowned. "Oh, it is the right approach in terms of respecting her. I don't know if it's the right approach in terms of talking her into doing what she wants to do. Would you mind if I talked with her a bit before I leave you two to have a serious discussion?"

"No. That sounds fine."

Summer was down to her panties. She walked over to where I was sitting on the bed, kissed me, and said, "You're the sweetest guy I've ever known."

* * * *

When Becky got home, she said to me, "Hey! You're here! That's a surprise."

Summer and I stood up from the couch. I said, "We've got some big news to tell you."

"What?"

I held up Summer's hand that I was holding. "We are now boyfriend and girlfriend."

"Really! That's great! Congrats."

Becky gave us each a hug. She seemed genuinely happy for us. Then she asked, "Have you told Kevin yet?"

"Last night," said Summer.

"What did he say?"

"He's happy for us. And he wants to make love to me on Saturday, which I'm fine with. It's time. I'd really, really like for you and Matt to make love at the same time."

Becky frowned. "I don't think you realize how big of a step you are talking about taking."

Summer said, "I know that half-siblings like Kevin and me shouldn't make love, and full siblings like you and Matt--"

"That's not what I'm talking about," said Becky, cutting Summer off. "Let's sit down at the dining table."

We all sat down at the dining table.

Becky asked Summer, "And what do you want to have happen on Sunday night?"

Summer took a big breath. "I want to make love with Matt while you and Kevin make love."

Becky shook her head. "What you are talking about is nothing like the first time you and Steve made love. It would be like that in that all of us are strongly attracted to each other, but with Steve, it was just another step in the progression of a relationship that you could have bailed out on at any time. What you are talking about is making a romantic square." Becky held up her hands and made a square with her thumbs and index fingers. "Once we form that square, none of us can bail out of it without hurting everyone else. If you break up with Matt, that hurts Kevin and me. If I break up with Kevin, that hurts you and Matt. If we do Saturday and Sunday like you want, then you have to eventually marry Matt and I have to eventually marry Kevin. Anything short of that, and we all end up hurting each other. Are you ready to commit to marrying Matt?"

I felt my jaw drop. I looked at Summer, and she too looked shocked by what Becky had said. But Summer quickly pulled herself together.

"When Matt and I were talking yesterday, one of the things we stipulated before agreeing to be boyfriend-girlfriend was that there wouldn't be any limits on our relationship. We didn't discuss marriage, but I realize now that that was what we implied. I'm good with saying that marrying Matt is something I want to work toward." Summer turned toward me. "What are your thoughts, Matt?"

Was this gorgeous, wonderful woman really open to marrying me? She was saying the right things, but I couldn't fully accept it at the moment. "We did agree to not put any limits on our relationship. I'd love to work toward marrying someday."

Summer turned back toward Becky. "Let's put all of our cards on the table. I'm in love with Kevin. I want to be his girl forever. I want Matt in my life forever and am happy to work toward marrying him. Let me put Kevin's cards on the table. He's in love with me and wants to be my guy forever. He's thrilled to be dating you, and I'm sure he'll agree to the idea of working toward marrying you." Summer turned to me. "Matt, put your cards on the table."

"Summer, you and Kevin are much further along in your relationships than I am. You only became my girlfriend yesterday. I'm thrilled that you are and want to work toward marrying you someday." I turned toward Becky. "With Becky, my relationship with her is more important than making love. I'm fine with whatever she wants to do."

Summer turned toward Becky. "You're the one who's been cagey about where you stand. Time to put your cards on the table."

Becky sighed. "Summer, how do you know that Kevin won't ever cheat on you? He's a lot like Steve."

Summer leaned her head a little to the side as she thought. "I've discussed this with Kevin. What's to keep him from hooking up with some woman while he's traveling for business? He travels two or three days every week."

"What did he say to that?" asked Becky.

"He said that he's matured a lot dating you. Now, women that he could impress by spending money don't appeal to him. He's also realized that his dad never cared much about any of his marriages. He was fine with putting them at risk. His dad had to know that he'd be caught if he kept cheating, and yet he kept cheating. Kevin has realized that his dad's attitude was 'Maybe the next marriage will be better'. To Kevin, being with you and me is the best he'll ever find because he knows that he'll never find two women who he respects and who are fine with him being with both of them. So he's promised me that he'll never put what he has with you and me at risk. And his actions have been consistent with that. He calls me every night when he's on the road. And he calls you too, right?"

"He does," said Becky with a slightly defeated look on her face.

"Look," said Summer to Becky. "I get that this is a big risk. But there are no safe relationships. I thought I did everything right with Steve. I thought I was a great wife to him. And he cheated on me before we got to our third anniversary. What we've been doing has made both Kevin and me the happiest we've been in our lives. We think taking the next step will make us even happier. We think the benefits of taking that step outweigh the risks."

Becky didn't respond to that. Instead, she looked away from us and drummed her fingers.

Summer said, "Where do you stand with Matt? How strong would that side of the square be?"

"Let me discuss that with Matt alone," said Becky. She stood up, and Summer and I did the same. Becky moved over to the couch, and Summer headed to her room.

"Let me know what you decide," said Summer before closing her door.

I sat down next to Becky on the couch.

Becky asked, "What are your thoughts on Summer, Kevin, and me?"

"Why don't you go first?"

"Because I'm the big sister, and I want you to go first."

I laughed. "Okay." I thought for a moment. "Before yesterday, I was in a similar place with both you and Summer; I was in the Friends Zone, but the part of the Friends Zone that has benefits. I preferred making out with you to making out with Summer, but, with Summer, I had hope that she might want to be my girlfriend someday, whereas you had made it clear that you didn't want to become more involved and were only giving me blowjobs until Summer started doing that."

"Did you feel that what you and I did was wrong?"

I scrunched up my face. "Yes, but..." I shrugged. "We had reasons for doing it, it was a lot of fun, and it didn't seem to hurt your relationship with Kevin. We both knew upfront that it wouldn't lead to us being an exclusive couple, and we've always been prepared for it to end."

"What do you think of Kevin?"

"He's okay. We get along well. Actually, we get along surprisingly well considering how much I make out with his girlfriend in front of him."

Becky nodded.

"Anything more?" I asked.

"I can't think of anything." Becky shifted. "I feel like I've been the Big Sister to all three of you. When Summer crashed my date, it was clear to me that she was infatuated with Kevin. My goal with her was to get her to slow down, not make any major commitments, and to hopefully get her infatuation with Kevin to grow into love. I was glad when she spent time with you as your mid-girlfriend. I felt that helped her with slowing down with Kevin and being a friend to him rather than just being overwhelmed by him. I was disappointed that she didn't give you more benefits."

I was disappointed too. I asked, "Did you enjoy Saturday nights with me?"

"I freaking loved Saturday nights with you. After being with Kevin on the date, I was ready to be in charge. And you let me be in charge. You let me be Big Sister. And I found that so freaking hot." She sighed for a moment. "I loved giving you blowjobs. Complaining about Summer not taking care of you was an excuse to do what I wanted. I loved making you moan. I loved making you come. And it made our talks in my bed afterward so much more poignant."

I was blown away by this. I had no idea she had enjoyed giving me blowjobs so much. "You could have let me know..."

"I was afraid that if I let you know, then you'd start trying to move us on to making love, and I was already struggling to not do that. I came so close to fucking you the night of my first date with Kevin. And every Saturday after that, I was tempted to fuck you. I loved that it was my choice; that you weren't pressing me to fuck you. But at the same time, I hated that it was my choice. I knew it was so wrong, but I also knew how easily I could make it happen. The reason I didn't let you eat me was that I knew that if I did, I'd have made you fuck me."

This was so amazing to me. But at the same time... "Why didn't you give into temptation? We could have fucked in your bedroom on Saturday night, and Kevin and Becky wouldn't have known."

"Oh, they would have figured it out. We would have looked at each other differently. We would have acted differently. And I don't think Kevin would have taken it well; his girlfriend fucking someone else. I've never worried about you and me. I've always worried about Kevin and about you and Summer. I felt like if we made love too soon, the rest of the romantic square would break apart."

"I can see that it would have been unlikely we could have kept it a secret for long." I took Becky's hand. "I want Saturday to be the start of you being my girl; my romantic partner. You're amazing, and I love talking with you and being with you. Sex with you is the best I've ever had because you're so hot when we make out. I like being with Summer, but I know I'll never be the number one in her life. I want you to be the number one in my life and for me to be the number one in your life."

Becky turned and kissed me. "I want to be your girl. You're pretty amazing yourself. No guy has ever gotten me so hot. And you're so easy to be with. Be with; talk with; do things with. I want to be the number one in your life and for you to be the number one in my life."
We kissed. And we kissed and kissed. It was wonderful knowing she felt toward me how I felt toward her. Tonight was so unbelievable. First, Summer said she wanted to work toward marrying me, and now Becky wants to be my girl. This was beyond a dream come true for me - I never would have dared to dream so big.

Becky broke off our kisses. She smiled and said, "I think we've put all of our cards down on the table. But what do we want to do? Not just Saturday night, but long-term?"

I put my arm over Becky's shoulders again and took her hand. "Do I want us to be exclusive? Yes. Do I think it would work? No. I think at least publicly, you and Kevin have to be a couple, and Summer and I have to be a couple. Summer strongly believes that for Kevin to be happy long-term as your boyfriend, he has to make love to you regularly."

"I don't think any of us can fake being a couple. You and Summer need to love each other. Kevin and I need to love each other. I'll love Kevin in a different way than you. And you'll love Summer in a different way than me." Becky paused for a moment. "Something that came up when I was researching cheating is that your mind makes you fall in love with the one you fuck. If we're going to make our romantic square work, I need to make love regularly with both you and Kevin. And you need to make love regularly with both me and Summer."

I laughed. "That sounds so crazy."

"I knew this day was coming. I thought it wouldn't happen for a while. I thought it would take you and Summer longer to raise your relationship to the point where you'd want to get married someday. I didn't want to rush it because I was worried about Kevin cheating on Summer and me in the future. But I came to accept doing what it'd take to make the romantic square work. And I'm super excited about becoming your girl."

* * * *

Saturday night, Becky came out of her bedroom wearing a purple dress that had an outer layer that was all lace and sequins. There was almost no material above her bust - instead of shoulder straps, it had straps that went horizontal to her arms. Becky twirled in front of us and the bottom of the dress floated away from her legs. The dress emphasized her narrow waist and full hips. Becky wasn't as curvy as Summer, but she still had wonderful curves.

Kevin said, "I'm going to marry that beautiful woman someday."

Becky replied, "I'll give you a big kiss after the pictures."

Kevin put his arm behind Becky as they posed for me to take a picture of them with his camera. I took three and lowered the phone.

"You look so beautiful," said Kevin as he wrapped his arms around Becky. They lovingly kissed.

"We need to go or we'll be late for our reservation," said Summer.

Kevin and Becky walked hand-in-hand toward the door. Summer and I fell in behind them, and I took her hand. We had decided to keep doing things as much as possible as we had been doing things. Don't change what works. The only difference so far was that Kevin slept with Summer last night. Kevin and Becky had their usual Saturday morning private time this morning but didn't fuck. Our first lovemaking would happen tonight after we finished the movie.

On the drive to the restaurant, Becky was extra playful with Kevin. "My boyfriend brought up the 'M' word. Is he hoping to get lucky tonight?"

We all chuckled at that.

"Oh, yes," said Kevin. "I'm definitely hoping to get lucky tonight." He turned his head. "How about you, Matt? Are you looking to get lucky tonight?"

"I am."

"By the way, you have an absolutely gorgeous girlfriend. You're a very lucky man."

Summer and I were holding hands in the backseat. We turned toward each other and smiled. I squeezed her hand. "I am a very lucky man."

I took pictures of Kevin and Becky in front of the restaurant. When we were seated at our table, we did the usual thing where I sat across from Becky. I leaned forward and said to her, "You look so beautiful tonight. Kevin is very lucky to have you as his girlfriend."

We chatted amiably through the meal. There was extra electricity as we did. Anticipation was in the air. We all knew that tonight we would do what we've been wanting to do. We talked as a group for most of the meal instead of our usual breaking into two talking couples. I felt like we all were leaning into making our romantic square together.

When we got into the apartment, Becky said, "Everyone change clothes. The dress code for movie time is T-shirt and shorts with no underwear, no shoes, and no socks." She and Kevin went into her bedroom while Summer and I went into ours. We had decided that I'd continue to keep my clothes in Summer's bedroom and sleep there. Eventually, we'd get a three-bedroom apartment, Kevin would officially move in with us, and the third bedroom would be his office and where he kept his clothes. Becky's closet was almost full, and Kevin kept giving her expensive dresses to add to it.

I stripped down while watching Summer strip. She was a damn fine woman. Kevin was lucky to have her as his girl. And I was lucky to have her as my girlfriend.

I finished dressing before Summer and stood waiting for her. Once she was dressed, she came over and kissed me. "I hope you have a great time tonight."

"Thanks. Same to you."

I did want Summer to have a great time tonight. I knew that tonight was the fulfillment of what she had been dreaming about for a while. I wanted Summer happy, I was thrilled that part of her happiness would come from being with me tomorrow night, but I was accepting that a bigger part of her happiness would come from being with Kevin tonight. Just like the bigger part of my happiness would come from being with Becky.

We went out and sat down on separate couches. Summer started looking for a Rom-Com to watch. Kevin and Becky came out of her bedroom, and Becky sat down on "our" couch next to me. As I put my arm over her shoulders and took her hand, we kissed. I said, "You looked so beautiful in that dress."

Becky smiled bashfully. "Thanks."

Summer started the Rom-Com, and we quietly watched. At one point when the movie got slow, Kevin and Summer started kissing.

"Hey! No starting early!" said Becky.

We all laughed, and Kevin and Summer stopped kissing.

The anticipation almost got painful toward the end of the movie. As soon as the final credits started, I saw Kevin attack Summer. Becky and I started kissing. When I tried to push my tongue into Becky's mouth, she stopped me.

"Let Big Sister be in charge. Move so that you are against the couch arm and take off your shirt."

"Okay." Once I did so, Becky moved forward and sucked gently on my nipple.

"Like that?" Becky asked me as she looked up at me with a smile.

"I do." Though I liked making Becky happy even more.

Becky sucked on my other nipple for a little bit before spinning around and leaning back against me. She twisted her head back and leaned upward. I leaned down, and we were kissing. Becky took my hands and guided them under her shirt. She then lifted her shirt up so I could bring my hands up to cup her breasts. We kissed languidly as I squeezed Becky's tits and played with her nipples.

We heard a sound and both looked over at Kevin and Summer. Kevin was seated on the couch and was loudly kissing a standing naked Summer all over her crotch area. He stopped, looked up at her, and said, "I've been waiting for this night for so long."

Summer ruffled his hair and said, "I've been waiting for so long too."

Becky looked back at me and said, "Let's move to the other side of the couch."

As we exchanged ends, Becky stripped off her shirt. Again, I put my back against the arm of the couch, and Becky leaned back against me. From this end, we had a clear view of Kevin and Summer. Summer was kneeling between Kevin's legs and licking his cock.

Becky whispered to me, "She's finally getting the man she desperately wanted."

"And you don't desperately want me?"

"I want you," said Becky as she kissed me. "But it's been different between Summer and me."

"How so?" I asked as I gently played with Becky's nipples.

"She started with being madly in love with Kevin and desperately wanting him. She's come down from there, become more aware of Kevin's flaws and the problems in being his girl, and her love for him has matured. Whereas I fought feeling anything for you at the beginning but eventually accepted that you make me happy in a way no one else can."

Becky took my right hand from her tit and moved it downward. She set it on her stomach just above her shorts. She then raised her butt and slid her shorts down to her knees. The whole time, both Becky and I watched Summer and Kevin. Kevin was rubbing Summer's shoulders as she orally pleasured him. She was drawing out the blowjob, constantly varying the action. Becky grabbed my hand and moved it down to her pussy.

"Make me happy," Becky whispered to me.

I parted my sister's pussy lips and slipped my finger inside. I quickly found her clit, made a gentle circle around it with the tip of my finger, and then moved lower. I slowly explored all of Becky's pussy while coating my finger in her juices. While doing all that, I continued to watch Summer and Kevin. Summer was now getting serious about the blowjob, bobbing her head up and down on Kevin's cock. Kevin had his eyes closed and his head bent backward to rest against the back of the couch.

"Taking notes?" I whispered teasingly to Becky.

"More it's making me happy to see them happy. Summer in particular. Life was very unfair to her. And seeing how happy they make each other makes me feel better about what all four of us have committed to." Becky kicked her shorts down so they were only on one foot. "Keep working your Big Sister's pussy. I'll let you know when I want you to start rubbing my clit."

Becky tilted her head up, and we started kissing as I continued to move my finger up and down her pussy. She was very wet now, and my cock was rock hard as it poked into her lower back. Soon, it would be poking Becky in a much nicer place...

"I'm coming!" cried Kevin.

Summer kept her head bobbing up and down as presumably Kevin was draining his balls down her throat. She gradually slowed and finally stopped.

"Start rubbing my clit," said Becky.

I brought my finger up to her clit and started making circles around it.

"Like that for now. The right spot moves around. I'll tell you where it is as I get closer to coming."

"Okay."

I listened to Becky's breathing as I made slow circles around her clit. Kevin and Summer were now lying next to each other on their couch, kissing and whispering. They looked very much in love.

"Right side on top," said Becky.

I moved my finger to that part of Becky's clit and rubbed it a little firmly.

"Oh, yeah. Right there. A little harder."

Kevin and Summer turned so that Summer was lying in front of Kevin with her back against his front. Kevin had his head raised and rested in his hand while his other hand was draped over Summer. They both were watching us.

"Left side, center," said Becky between pants.

I moved my fingertip there and rubbed more firmly.

"A little lower. There! Right there!"

I continued firmly rubbing Becky's clit as I watched Kevin and Summer watch us. It was weird having them watch us, but Becky and I had been watching them not long ago. Kevin was probably recovering after that excellent blowjob.

"So good!" cried Becky as she pushed her body harder back against mine. Her pants got deeper and deeper, and then she was bucking against my hand. I kept up the pressure against her clit. Becky suddenly curled into a ball while tilting toward the back of the couch. Her thighs squeezed my hand hard, so I stopped moving my finger. I cradled my sister with my left arm as she continued coming.

Many moments later, Becky relaxed. She turned so she was on her hands and knees and climbed up to kiss me. "That was so good." She then spun around and flopped back against me like a rag doll.

Kevin was now between Summer's legs, eating her out. Summer gave us a quick smile and a wave and then went back to running her fingers through Kevin's hair.

Becky said, "Sit upright in the middle of the couch." I moved as she told me. Becky straddled me. "Squeeze my ass while you suck on my tits."

It was easy to suck on Becky's tits as she was keeping high up on her knees. I took one nipple into my mouth and sucked on it while I squeezed her ass with both hands.

"You make me so hot," panted Becky. "I want to keep making out like this until I can't take it anymore and I need you to fuck me."

I was fine with that. Totally fine with that. As Becky hadn't given me a blowjob, we were ahead of Kevin and Summer, and I wanted us to finish about the same time. The four of us had agreed this morning that we'd fuck in front of each other and, once the fucks were finished, we'd adjourn to the bedrooms where the couples could continue having fun in private.

"That feels so good!" moaned Becky. As I sucked on her tit, she wiggled her stomach back and forth, rubbing her pussy against me briefly. God, I wanted to fuck her. I wanted to grab her by her hips and slam her down on my hard cock. But I knew that was coming and also knew that the longer we waited, the better it would be.

I peeked around Becky to check on Kevin and Summer. Summer had her legs over Kevin's shoulders and was slumped against the couch with her eyes closed and her mouth open. She looked like she'd be coming soon.

Becky grabbed my head and moved it to her other nipple. "Make little sucks all around my circle. Find the sensitive spots."

I moved my lips to Becky's tit just outside the areola and sucked lightly on the boobflesh. I then moved a little counterclockwise and sucked again.

"That's a good spot!" cried Becky as she wrapped my head with her hands. "Suck there some more."

I sucked on that spot for several moments until Becky moved my head to continue on its circle. I continued sucking on her tit, finding another sensitive spot, moved over to her other tit, and found three sensitive spots there.

Kevin said loudly, "Oh, yeah, Summer. You're mine now."

Becky and I turned to see Kevin fucking Summer. Summer had her feet up on Kevin's shoulders.

"That looks like fun," said Becky. "We can do that later. But for now..." She grabbed my cock. "Are you ready to fuck Kevin's girlfriend and future wife? Before he does?" She grinned.

I smiled back at Becky. "You'll never be tamed, will you?"

"No." Becky moved my cock to her entrance. "Can you love an untamable woman?"

"I can."

Becky put the head of my cock inside of her and lowered herself down. I grabbed her ass with both hands to help support her weight. Becky dropped herself a little more, and then a little more, and then she lowered herself all the way down so that I was fully inside of her.

"Since that first time I straddled your lap and you sucked on my tits and squeezed my ass, I've wanted to fuck you this way. I've thought about it so often." Becky wiggled her crotch in a circle on my crotch. "You feel so good inside of me."

"I love you, Becky. You're so amazing."

Becky looked down at me briefly. "I love you too."

We kissed. As we kissed, Becky ground her crotch against mine in small circles.

"Fuck me!" cried Becky as we broke our kiss.

I had an ass cheek in each hand and lifted her up. Becky lifted herself too until only the head of my cock was inside of her, and then she dropped herself down. As she did, her tits flopped and bounced in front of me.

"It feels so good being inside of you," I said.

"It feels good having you inside of me."

Becky and I lifted her up, and she dropped herself down. We lifted her up, and she dropped herself down. We developed a slow, steady rhythm. As I would lift Becky, I'd squeeze her ass with both hands. I had only fucked on a bed before and nothing like this position before. This felt amazing. It was so hot seeing Becky's tits bounce in front of me as we fucked.

Suddenly, Becky stopped fucking me and kissed me instead. I had been close to coming, but my ardor cooled as we kissed. Becky ended the kissing and turned to look at Kevin and Summer. Kevin was fucking Summer in the missionary position on the couch, and Summer had her legs wrapped around his legs. Becky looked at me, smiled, and we resumed fucking.

Soon, Becky and I were back into the slow, steady rhythm. Becky closed her eyes as she bounced up and down on my cock. I continued squeezing her marvelous ass on every upstroke.

Again, Becky stopped fucking me to kiss me. "Can you slide forward some?"

"Sure."

I moved my butt to the edge of the couch while Becky crab-walked backward to keep my cock inside of her. She resumed kissing me, stroking her hands down my shoulders and forearms as she did. I ran my hands up her back, then down her back to her ass, which I gave a playful squeeze, and then back up again.

When we broke our kissing, we looked at Kevin and Summer. Summer was bent over the couch arm closest to us, and Kevin was fucking her doggie-style. Summer smiled at us and gave us a brief wave before grabbing the couch arm again.

Becky and I resumed fucking. Now that I was slouched down, the angle was different. Becky grabbed the back of the couch with both hands to help propel her up and down my cock. Her tits swung back and forth above me like two large pendulums.

"Are you ready to come inside me?" asked Becky. "To truly make us a couple?"

"I am. The first step down the road to forever."

Becky moved her feet so that they were inside my thighs. With her better leverage, she increased our rhythm. I spread my thighs wider and grabbed Becky on each side just below her waist. Becky kissed me while we fucked more quickly. She made a humming/moaning sound as we kissed. Then we ended the kiss and both gasped for air. We were fucking frantically now. I was slamming Becky up and down my cock with my hands as fast as I could.

"I'm about..."

"Fill me, Matt."

Pleasure overwhelmed me, and I came. I came hard, firing spurt after spurt deep inside my sister. God, it felt so wonderful; so right. We were committed now. No turning back.

We heard clapping, and Becky and I turned to see Summer clapping with a big smile on her face. She was sitting on the couch, and Kevin was sitting next to her. "That was wonderful!" she said cheerfully.

Kevin gave us a 'what-can-you-do' grin and stood up. "Come on, Summer. Time for bed." Kevin looked at us and winked. "But not necessarily sleep."

* * * *

Three years later
I walked into our house carrying the mail and closed the door behind me. I started opening it; bills would go to Becky and everything else would go to Summer. One piece of junk mail addressed to "Resident, 1792 Oak Cliff Drive" made me smile. There were no oaks in our neighborhood or near it. There were no cliffs in our neighborhood or near it. Our street name was a marketing fib. I smiled at that. We weren't the only ones who regularly fibbed to people.

Once I was done with the mail, I still had some time to kill as Becky hadn't come out of her bedroom yet. Publicly, it was her and Kevin's bedroom, but Kevin only slept it in on Sunday nights. I slept in it the other six nights.

I was very thankful to be working days now. I was working 7 am to 3:30 pm five days a week, which was a huge improvement. Two of those days were Saturday and Sunday, but that didn't change the amount of time I was with Becky on the weekends because I used to be asleep during those hours.

Kevin had gotten a VP of Sales and Marketing job at a local company. He didn't travel as much as he used to, but many of his trips were now international. He was traveling now.

I wandered over to one of my favorite parts of the house - the fireplace in the great room. On the right was Kevin and Becky's wedding picture, and on the left was mine and Summer's wedding picture. We had originally talked about having a double wedding, but each set of parents wanted to host a wedding. So on the Saturday of Memorial Day weekend a little over a year ago, Kevin and Becky got married in Kevin and Summer's parents' church. Two days later, Summer and I got married in my parents' church. At the time, two different weddings seemed a waste, but now I was glad that we did that as it gave each couple their own set of special memories.
The door to Becky's bedroom opened, and Becky came out. "Happy Birthday!" she said as she kissed me.

"Thanks." I stepped back and looked Becky over. "You look great." She did in her dark blue dress. Kevin bought her more conservative dresses now. No plunging necklines or splits in the gown to show off legs. This dress did hug her body tightly and show off her wonderful curves. It had shoulder pads and long sleeves, which made Becky capable of wrestling bears.

"I like this dress," said Becky as she slowly turned around in front of me to show it off. "Too bad I may not be able to wear it much longer." Becky finished her circle. "Having a baby changes a woman's body."

"That's getting a little ahead of yourself. You aren't even pregnant yet."

"Hopefully, I'll be soon."

The four of us had agreed that this would be the last cycle that Becky and Summer would be on birth control.

"Hopefully, you will be." I nodded my head toward the stairs. "Let's go get Summer."

We took the stairs down to the basement. At the bottom of the stairs, I could have turned left and gone into the garage. But I turned right into the studio living area that was publicly where Summer and I lived. I only slept one night a week there. When the four of us had first started discussing buying housing, we had thought we would buy two houses next to each other and the guys would slip through the backyard to the house they would spend the night in. But then Becky had found this place, and all of us thought it was perfect. It was a two-story house on a sloping lot with a basement, and each floor was quite large. The first floor had the master suite, the kitchen, and a great room. Upstairs was a media room and several bedrooms, one of which was an office for Kevin and another was an office for Becky. When we wanted to be together, we could easily do so. When we wanted privacy, we could easily do that too. And it was easy for the guys to discretely go to their bedroom of choice.

"Hey, Gorgeous," I said to Summer. "Here's the mail. Nothing looked interesting." I stepped back and admired Summer. "You look great in that dress." She was wearing a long, light-blue dress that made her blond hair stand out.

"Thanks. You look nice, too."

"Thanks."

I was wearing a suit and tie. We were going to a very nice restaurant to celebrate my birthday, so all of us were dressed up tonight.

"Let's go," I added.

We got into the Mercedes. Summer, my wife, got into the passenger seat. Becky, my other wife, sat in the back. On the drive to the restaurant, Becky leaned into the space between the two front seats, and the three of us had a pleasant conversation. I always enjoyed driving the Mercedes. Kevin viewed it as HIS car, but the rest of us viewed it as OUR car. I always enjoyed establishing my right to drive it.

"I'm so ready to be pregnant," said Summer. Becky and I laughed. "I was all up for being six months pregnant when I married." Summer had been outvoted on the timing of starting our families, three to one. "But you guys had a point that I've only come to realize."

"What's that?" asked Becky.

"I love our sex lives. But it's amazing that we're able to have sex four times a week every week after three years. Steve and I had dropped down to two or three times a week after a few years."

"You have a great point there," said Becky.

"I've been fine with four times a week," I added innocently.

Summer shoved me lightly on the shoulder. "Of course, you're okay with it. You're a guy. Kevin would like more than four times a week."

"I too have been surprised how well we've been able to keep up that pace," said Becky.

"I think it's because it's different every time during the week," said Summer. "Once with Kevin as part of a group, once with Kevin in private, once with Matt as part of a group, and once with Matt in private. With Steve, it was always the same - the two of us making love in our bed. I think the constant variety has kept up my appetite for sex. But back to my point - I think it's been good that we've had several years of lots of great sex. I am doubtful we'll be able to keep up the pace once the babies arrive, so I'm concerned about what that will mean for us."

"I agree," said Becky.

I said, "We'll cross that bridge when we get to it." I was not into worrying about things that might happen in the future.

We moved on to different topics for the rest of the drive. We then had a pleasant dinner and drove home. At home, we all went into Becky's bedroom.

"How are we going to do this?" I asked.

For my last birthday, the girls gave me an MFF threesome. They also gave Kevin one on his last birthday. Last year, they had been very tentative through the whole thing. I guessed that they had a better idea of what they wanted to do this time.

"First off," said Becky. "You take our dresses off us." She moved so that her back was in front of me.

"There's a surprise under Becky's dress," said Summer teasingly.

I grabbed the zipper and pulled it down. As Becky's back became exposed, I could see that she was wearing high-end lingerie - a black bra and a black corset.

Becky slipped her arms out of the dress and let it fall to the floor. She was wearing black panties that had only three straps in the back. Below that, she was wearing black stockings that were connected to her corset by black straps. She twisted her head to look at me. "You like?"

Becky looked sexy as hell. "I like very much, my wife."

When it was just the three of us at home, I called both Becky and Summer 'my wife'. I loved them both and was committed to them both. The only difference between Summer and Becky was a piece of paper.

Becky stepped out of the dress and turned around to model her lingerie for a moment. The panties had a small triangle over her pussy. Becky then bent down, picked up the dress, and moved out of the way for Summer to take her place in front of me.

"Similar surprise?" I asked.

"Unzip me and see," teased Summer.

When I unzipped Summer, I saw that she was wearing a taller black corset that had a bra incorporated in it. When she slipped out of the dress and let it fall to the floor, I saw that she was wearing the same black panties and black stockings as Becky. When she stepped out of the dress and turned around to model her lingerie, I saw that Summer's corset had only demi-cups that supported her large breasts but left the nipple and above marvelously exposed. She looked so fucking gorgeous.

"You like?" asked Summer.

"Very much so, my wife."

"You're overdressed," said Becky as she moved her hands toward my tie. My wives quickly undressed me and moved me toward the bed. Summer sat down on the bed and took my cock in her hand while Becky and I stood next to her. Becky started kissing me while rubbing her hands over my chest. Summer played with my cock for a little bit and then took it deeply into her mouth. She was so good at giving head. Becky didn't care for it much, but Summer loved it, much to my satisfaction. I put one hand on Summer's shoulder to help balance myself and rubbed Becky's stomach with the other.

One rule we had was that Kevin and I never discussed sex. What he enjoyed and what he did when he was alone with one of the girls was his business, and what I enjoyed and what I did was my business. So I didn't know if Kevin enjoyed Summer giving him head, though I had a strong guess that he did.

I pushed my tongue into Becky's mouth and brought my hand up from her stomach to squeeze her tit through her bra. Summer continued giving me head, sometimes sucking my cock and sometimes licking it. This was so good and so hot. Becky reached behind her, undid her bra, and tossed it aside. I then squeezed her tits one at a time directly.

Summer suddenly said, "Switch." She stood up, and Becky sat down on the bed. I kissed Summer while Becky gripped my cock and then started sucking on it. Like last time, I put one hand on Becky's shoulder for balance while I squeezed Summer's tits with the other. Damn, this was 'died and gone to heaven' wonderful. The corset's presentation of Summer's tits made them look amazing. I still had troubles believing that I had married this gorgeous woman. And that Becky was just as into me as I was into her. I loved my girls, and I loved making out with both of them like this. The girls had decided they would do this just once a year, but I wished they'd do it more often.

We continued making out until Becky said, "Next step."

Summer pulled back and gestured for me to lie down on the bed. The covers were already pulled down, and a beach towel was on the bed. "Lie down on your back," she said. As I clambered onto the bed, she asked me, "Have you decided?"

"Oh, God. Not this again," said Becky.

"No," I replied. "No point in deciding until I need to, which isn't for two weeks."

"Just checking."

I got on my back in the center of the bed. Becky lay down on my left, and Summer lay down on my right. Once we were in position, Becky gently grabbed my shoulder and turned me toward her until I was close enough for her to kiss me. Summer scooted up to press her tits into my back. She ran her hand up my forearm and up to my head, where she started running her fingers through my hair.

Summer said, "I always enjoy seeing you two kiss. I never feel jealous about it. I'm so glad you found in Becky that same kind of love I found in Kevin."

Becky and I snogged for a good long while until she pushed me gently away. I did a one-eighty and started kissing Summer. Becky moved close and pressed her tits into my back. She then started stroking my forearm and shoulder.

"I always feel some jealousy," said Becky as she pressed her tits more firmly into me. "I trust you two, so it's not bad. But I always have a feeling of relief when Matt comes back to me after he's been with you."

Summer and I snogged for as long as Becky and I had done while Becky ran her hand with the lightest of touches all over my body. When we broke, Summer smiled at me and then gave me a quick kiss. "I love you," she said.

"I love you, too."

"Move along, Summer," Becky chided playfully. "We don't have all night."

Summer removed her black panties, so now she was wearing only the black corset and the black stockings. She moved onto her knees as she replied to Becky playfully, "What? Do you have a movie you want to watch tonight?" Summer walked on her knees toward my head. She looked so damn sexy in the black corset and stockings and with her tits practically on a platter.

"I don't want Matt falling asleep when it's my turn."

Summer snorted. "Oh, I think we'll make it exciting enough to keep him awake." She then grabbed the headboard of the bed and straddled my face. "You know, Becky, if we do your plan, you'll have to give up Matt for quite some time."

"Oh, God. Not this."

Summer wanted that, once the girls were off birth control, she'd only make love to Kevin and Becky would only make love to me until both of them were pregnant. Becky wanted that she'd only make love to Kevin and Summer would only make love to me.

I cupped Summer's full ass in my hands, thrust my tongue forward, and parted Summer's pussy lips. I began licking her pussy with the tip of my tongue.

"Like I said before," said Becky. "There's a greater risk of birth defects if do your plan. But I mainly oppose it because there's so much genetic testing nowadays, and genetic testing will only become more common. What if our son's wife wants our son and her to get genetic tests to see their ancestry? Then only my relatives would show up as being related to him."

The girls weren't arguing with each other; they were making their case to me. Kevin wanted us to continue as we have been doing and let the best sperm get the girls pregnant. I was to be the deciding vote.

I didn't want to discuss the subject. Feelings would get hurt, and I was in no rush to do that. I'd start thinking about it when a decision needed to be made and not a moment sooner.

Instead, I began lapping up the sweet nectar in Summer's pussy. As I did, I felt Becky licking and kissing my cock while gently stroking it with her hand, all of which felt great. I was in no hurry to get Summer off as I enjoyed eating her out and I was enjoying what Becky was doing to me.

"Matt, I love what your tongue is doing to me," cooed Summer. She loved both giving and receiving oral sex.

"He is really good with his tongue," said Becky. "He knows how to get me hot and then how to finish me off."

"I like how he goes slow." Summer let out a low moan. "Oh, yeah. Keep that up."

I wondered if the comments about how good I was at pussy-eating were implied criticisms of Kevin. Again, the rule was no discussion about how the other was at sex, but I couldn't help but picture Kevin as being too impatient to get to the fucking to be good at pussy-eating.

I darted my tongue inside Summer's pussy to get some more nectar, and Summer shuddered. After a quick taste, I went back to working my tongue up and down the inside of Summer's pussy lips, I felt her juices coating my face.

Becky took my cock inside her mouth and slowly bobbed down and up. I moaned into Summer's pussy. I was now more than ready to start fucking, so I moved my tongue up to Summer's clit. I made a circle around her clit.

"Oh, yeah!" cried Summer.

I started making the alphabet on top of it. A...B...C...D...

"Oh!...Oh!...Oh!"

I sucked on Summer's clit, and that sent her over the edge. She made a strangled half-cry as she bucked on top of me. I kept a firm grip on her ass she did. Becky removed her mouth from my cock and gripped it firmly by its base as I assumed she was watching her best friend come.

When Summer was done coming, she slumped forward, holding herself upright by keeping ahold of the headboard. I gave her ass a gentle squeeze. After a few moments, she swung off me. "What position do you want?" she asked as she did so.

"Doggie-style."

Summer quickly moved onto her knees in the center of the bed and I moved behind her. I took a moment to appreciate the marvelous ass that was in front of me. Above was the black corset and below it were the black stockings. A black garter strap on each side connected them.

Becky grabbed my cock and guided it to Summer's pussy while I gripped Summer's hips. Once the head of my cock was inside of Summer, I pushed forward.

"Yeeesss!" moaned Summer as she arched her back.

"Fuck her, Matt," ordered Becky. "Fuck my best friend."

I plunged deeper into Summer, sliding through her slick warmth. Once my cock was halfway into her, I pulled back until my cock was almost out of her. Becky put her hand on my ass and gently pressed me forward as I thrust into Summer again. I stopped, pulled back, and, once again, Becky pushed me forward. This time, I didn't stop until my cock was buried completely in Summer.

"Like that?" asked Becky of Summer.

"Love it!"

I started fucking Summer slowly.

"You like fucking your wife?" asked Becky.

"Of course."

The question struck me as odd. Becky never referred to Summer as my wife. Doing so emphasized that Summer's relationship with me was different than my relationship with her, which we all avoided doing.

I was getting more and more into fucking Summer. She was rocking her ass back to meet my thrusts. She looked so hot in the black corset and stockings.

Becky moved next to me on her knees and started running her hand all over my back. She nibbled on my ear lobe briefly and then said quietly and sultrily into my ear, "Next month, you'll get to fuck her the whole month. And, hopefully, you'll get her pregnant. You'll make her big tits even bigger."

Talking about knocking up Summer made electricity flow up and down my spine. Did I want to knock up this gorgeous woman I was fucking? Hell, yeah.

Becky put her hand on my butt and pushed me gently forward as I thrust into Summer. "I want you to get her pregnant, Matt. I want you to put your baby inside of her." Becky then nibbled on my neck while continuing to push me deeper and deeper into Summer.

Becky suddenly said to Summer, "Do you want help coming on your husband's cock?"

Summer fucked me for a couple more cycles and then stopped moving. "Sure." She moved forward so I came out of her and flipped over onto her back. "I'd love to come while Matt is fucking me."

Becky grabbed my cock and guided it to Summer's entrance. Once my cock was inside of Summer, Becky lay down beside Summer while moving her hand to the top of Summer's crotch. I stayed upright with my knees spread wide as I plunged into and out of Summer, Becky slipped her finger inside of Summer's pussy lips and apparently to her clit.

"Tell me where you want me to rub," said Becky.

"That side but lower."

We hadn't done this the last time we had a threesome. Was it something they had done with Kevin? I wasn't going to ask. Instead, I concentrated on fucking my gorgeous wife, watching her big tits bounce as I fucked her.

"Oh, yeah! Oh, yeah!" cried Summer. "Right there."

Summer brought up her leg that was opposite of Becky and put her foot onto my shoulder. While she did that, she rotated her crotch toward Becky. Becky continued rubbing Summer's clit in tight circles. The race was on - would Summer or I come first?

I closed my eyes to try to reduce the stimulus. Watching Becky working Summer's clit was so hot. To my knowledge, Becky and Summer hadn't touched either romantically or sexually before.

"Uh! Uh! Uh!" called out Summer as I continued fucking her. Her pussy felt so good. I knew I wouldn't last much longer.

"YES!" cried Summer as I felt her pussy start spasming on my cock. I opened my eyes to watch Summer open her mouth in a wordless scream. I continued thrusting in and out of her as she came.

Becky took her hand away from Summer. I bent forward and put my hands on either side of Summer's arms in the missionary position. I started pounding her hard. I surrendered myself to the pleasure and shortly was coming myself.

Becky was sitting next to me, rubbing her hand over my back. When I started coming, she said, "Yes. Yes. That's right. Fill her up, Matt, with your potent sperm."

I stopped moving and enjoyed the sensation of the last few spurts inside of Summer. Once that was done, I bent down and kissed Summer. "I love you."

"I love you too."

I pulled out and rolled over so I was lying on Summer's side facing her. Becky hopped off the bed and came around to the other side while Summer moved away from me. Soon, I was lying in the center of the bed. Becky lay down to my left. Summer put her hands on me and twisted me to face Becky, who started kissing me. As Becky and I did a series of gentle kisses, Summer reached down and began stroking my limp cock. It would take me a bit to recover.

Becky quickly escalated the intensity of our kisses, and soon we were Frenching. Summer played with my nipples as she lightly pressed her tits against my back.

Pulling away from me, Becky said, "Eat me, Matt." She stripped off her panties and began moving toward the center of the bed. She looked hot with her exposed tits, her black corset, and her black stockings. I got on my knees and moved down the bed to make room for her. Once Becky was lying on her back in the middle of the bed, I lay down between her legs, took her ass cheeks into my hands, and brought my mouth to her pussy. Becky bent her legs and put her feet outside of my shoulders. I parted her pussy lips and began lapping up Becky's juices. She was quite wet. I slipped my tongue inside of her vagina to get some more juices.

"Oooh!" said Becky.

I kept licking Becky's pussy. She liked me to lick her pussy all over for a while before going to her clit.

Becky said to Summer, "Would you help me?"

"Sure."

Summer moved her hand to above Becky's slit and slipped a finger inside. Summer said to me, "I'll work her clit. You stay below that."
Again, I wondered if the girls had discussed things they wanted to try during our threesome.

I licked both sides of Becky's pussy while Summer rubbed her clit. Becky made moaning sounds. When I pushed my tongue inside of her again, she said, "That's it. Fuck me with your tongue."

I curled my tongue and made it as firm as I could and then pushed it into Becky. I pulled back and push forward again, fucking Becky with my tongue like it was a little cock. In the meantime, I could tell that Summer was rubbing Becky's clit.

"Jesus! This feels great!" cried Becky.

I redoubled my efforts to fuck Becky with my tongue. I couldn't penetrate very far, so I tried to make up for that with frequency. Becky was moaning up a storm. After not too long, she clamped my head hard with her thighs as she came. I stopped tongue-fucking her and waited. Not much later, she relaxed and opened up her legs.

"You ready to fuck me?" asked Becky with a wicked smile on her face. She was taking charge of our fucking as usual.

"Yes!"

"Lie on your back then."

Becky and I exchanged positions. Once I was lying on my back, she straddled my crotch. She looked so great in the black corset and stockings. "You ready to give me a thorough fucking?" she asked. "To make me come?"

"Yes!" I had come not long ago, but she was getting me all excited again.

Becky grabbed my cock and guided it into her. Once I was inside of her, she slowly let herself down on my cock. "Oh, yeah, Matt. I love fucking you." She let herself down more until my cock was fully buried inside of her. She then started rocking her hips while keeping mostly upright, moving my cock slowly inside of her a small amount while grinding on me.

"You're so damn sexy, Becky." Her black corset added to her natural hotness. I loved seeing her tits, and I felt the urge to touch them. I moved my hands up and cupped her tits while she continued to rock and grind on me.

"Pinch my nipples, Matt."

I squeezed Becky's nipples between my fingers as I squeezed her breasts. She closed her eyes as I did that.

"Get me hotter, Matt."

I took my hands off her tits and gripped her nipples with my index fingers and thumbs and squeezed lightly. Becky loved having her nipples played with. I then cupped her tits and squeezed her nipples between my fingers. I alternated squeezing and pinching Becky's nipples as she continued to rock and grind on me until she suddenly bent forward so her face was a little above mine.

"Fuck me, Matt!"

I grabbed Becky's ass and began moving her up and down on my cock while Becky raised and lowered herself. We were quickly in a great fucking rhythm. Becky lightly bit her lip, a look of pure sexual bliss on her face. She was such a great fuck.

To get a better grip, I moved my hands up from Becky's ass to the side of her waist. Now, I could thrust up into her better. Becky changed her position slightly so she could better receive my thrusts.

Summer had been sitting close to us on the bed watching us, but now she moved onto her knees. She grabbed Becky's ass with her hands and started slamming Becky down onto my cock.

"Fuck that pussy, Matt," said Summer. "Fuck your sister's hot pussy. It's your favorite pussy to fuck, isn't it?"

Summer helped us fuck for a little more and then she crawled backward up the bed. She started rubbing her hands in big circles around my nipples. She eventually moved so that her head was close to my ear.

"Fucking Becky is the best, isn't it Matt," Summer said softly in my ear. "She's a much hotter fuck than I am." Summer squeezed my nipples between her fingers.

I groaned. I had slowed some, a little tired from my earlier fuck, but Becky was still going strong. She was riding me hard and fast. And then she leaned forward. Summer withdrew her hands from my chest to give Becky room. Becky kissed me, and, while we kissed, she did her humming/moaning sound she made when we kissed as we fucked.

Becky broke off the kiss and resumed riding me. I switched my hands back down to her ass and continued to help her move up and down.

Summer said quietly in my ear, "Imagine how much hotter fucking her will be once she's off birth control." I groaned again. "Don't pay attention to what she says; she's madly in love with you and wants your baby. She wants you to knock her up. Don't you want to knock her up?"

I felt a drip fall on me. Sweat from Becky. Sweat was running down from her hair and was coating her face. But she didn't slow. She kept riding me hard. Had she heard what Summer said?

Then Becky suddenly stopped. "Matt!" she cried as I felt her pussy spasm on my cock. Becky looked straight ahead with a glazed look in her eyes. I reached up and cupped her tits, both to provide her better balance as she came and because I loved feeling her tits.

We held that position for several moments, and then Becky looked down at me and smiled. She resumed riding me, and I dropped my hands back to her ass to help her do so.

Summer put her hands on my chest and started running her fingers through my chest hairs. She said softly in my ear, "You two make such a great couple. And you'll make great parents. Parents to your baby." Summer pinched my nipples. "Are you ready to come in Becky? Just like you will next month? But next month, you'll be getting her pregnant when you come in her."

The thought of knocking up Becky pushed me over the edge. I was coming. I felt the first spurt moving up my cock and into Becky.

Becky stopped moving. She put her hands on my chest to hold herself as spurt after spurt shot into her. She closed her eyes to savor the feel of my coming inside of her.

Once I was done coming, Becky leaned forward, kissed me, and said, "I love you."

"I love you too."

Becky climbed off me. Shortly thereafter, they got off the bed, took off the corsets and stockings, and changed into cotton panties. I wiped myself with the towel and tossed it into the dirty clothes. My wives climbed back into the bed as I lay down on my back. Becky put her head on my right shoulder, and Summer put her head on my left. I put my arms around them and pulled them into me as a hug.

I let out a contented sigh, and then my thoughts turned to the decision I would soon have to make. Did I want to knock up Becky? Absolutely. But I also wanted to make her happy, which would mean knocking up Summer instead of her. Did I want to knock up Summer? Absolutely. That was the thing - I wanted to knock up both of my wives. I could go along with Kevin's idea and hope that my sperm did the job with both Becky and Summer, but I'd never know if it did.

Tough decision.
