A Flirting Workshop with My Sister

She’s such a flirter! And then she starts flirting with me.

I published this story on 2/7/22. My original plan for the story was for it to be about fifty percent bigger than what I published. However, the final sex scene wasn't working, I knew I needed to rewrite it, but I wanted to be finished with the story and was out of ideas. So, I decided to end the story the first place I could and cut everything beyond that. I got a lot of negative comments on the ending of the story. I took this and all my other stories down in January 2023.

As I was preparing this story for republishing, I thought about changing the minor character Dmitri's home country from Ukraine to Belarus. Sadly, my lines "Things are very unstable in Ukraine. No one feels safe. Much better to take what money you can and move to America" were very prophetic. In the end, I decided to not make the change.

For republishing this story, I've decided to restore what I had cut out before. Since I originally published it, I've come up with ideas for the final sex scene that I like better than what I had. The original version was like most of my stories in that it ended right after the brother and sister had sex for the first time. This version will be unique for me in that it explores how Eli and Z handle being a couple. This version will be one of my longest stories.

We were interrupted by a knock at my dorm room door. "Come in!" I yelled. I hoped it wasn't who I thought it was.

"Hi, Eli!" said my freshman sister Z in a slightly higher-than-normal tone. I rolled my eyes and groaned inwardly before turning in my chair.

"Hi, Z," I said with my voice full of annoyance. "What are you doing here?"

Z ignored my reaction, instead offering her hand to Landon, the friend I was studying with. "I'm Z," she said with friendliness turned up to ten. "Eli's little sister." Landon stood up from my bed and shook her hand. Landon and I were both sophomores. Z leaned forward to Landon and said conspiratorially, "Mom has me check in with Eli regularly so he can keep an eye on me."

"Hi! I'm...um...Landon. Landon Chu." Landon was acting like a pretty girl had never introduced herself to him before. This was going to be bad.

Z looked at the book Landon had set on the bed. "Are you studying Organic Chemistry?" My sister chewed her gum as she waited for Landon's answer.

"Yes."

Z tilted her head slightly as she looked at Landon. I knew exactly what she was going to say. "Is that the chemistry between males and females?" She had used that line before on my friends.

"Well, um, it...it could be." Landon was totally flustered. I had warned Landon that my sister might drop by, and, if she did, she would flirt with him even though she had no interest in him. My warning him obviously did no good. "I mean I guess it could be, but that's not what we're studying now."

I said with a little heat. "We're studying. I have a lot of studying to do. What do you want?"

Z pretended not to hear me. She asked Landon, "Are you a pre-med major too?" She looked at him adoringly with her blue eyes wide as she chewed her gum and twirled some of her shoulder-length blond hair around her right index finger.

"Yes. Yes, I am." Landon was probably the smartest guy I knew, and he sounded like his brain was mush under her spell.

"I could never be a pre-med major," Z said as she twisted her body slightly back and forth. "I could never learn all the stuff you have to learn." Z's movement drew Landon's attention to the silly mathematical formula on her T-shirt. The formula was Distance Raptor divided by Time Raptor equals Veloci Raptor. The last two words were printed over a black velociraptor that covered most of Z's left breast. Landon was quiet for a moment as he read the shirt.

Z said, "They're 34 C's."

Landon said in a surprised tone, "What?"

"They're 34 C's. You were staring at my chest, so I thought you were trying to guess my bra size."

Landon had a horrified look on his face. "No," he said as he shook his head back and forth quickly. "No. I wasn't--"

"You thought they're a different size?"

Landon was on the verge of panic. He almost shouted, "I was just reading your shirt!"

"Oh, okay." Z went back to chewing her gum, twirling her hair, and twisting gently back and forth. She was wearing a short, white cotton skirt. No one wore a short skirt in the dorm except Z, and I think she only wore them when she came to visit me. The skirt swished back and forth, drawing my and Landon's eyes to Z's legs. She had great legs, still well-tanned after spending a lot of this summer sunning.

I said loudly, "WHAT DO YOU WANT, Z?"

"I thought I'd drop by and say hi." Z turned back to Landon. "You must be awfully smart." She said that with awe in her voice. She was very smart herself, with an SAT better than mine. "Eli is super smart, and he's asking you for help with homework."

Landon turned three shades of red. "Well, I, um...well, I am..."

"You said hi, so you can leave now," I said loudly. I was tempted to call my sister by her first name, which she hated. "Z" came from our last name, Zajaczkowski. I took a moment to collect myself. I said firmly, "I have a lot of studying to do."

Z gave me a cute, exaggerated frown. It was so funny looking that I felt my anger leave me. "I was enjoying talking with Landon." She turned to him and stuck out her hand. "It was nice meeting you, Landon."

Landon pumped her hand enthusiastically. "It was nice meeting you."

Z turned and headed toward the door, swaying her hips a little more than normal as she walked. She opened the door, turned, waved goodbye to Landon with just her fingers, and then closed the door.

Landon turned to me. "WOW! Your sister is amazing."

"She's annoying as hell. She pulls this shit all the time."

"Do you think...she'd go out with me if I asked her?"

"No. If you talked to her again without me around, she'd be friendly but would cut the conversation short. 'Hi, Landon. Nice to see ya. How is Organic going? Gotta go!'"

Landon was disappointed by this but then seemed to brush it aside. "She seemed to really like me."

I was getting frustrated. "This is why her visits drive me nuts. She drops by, flirts for a little while, and then leaves me to give the guy the bad news. She likes you as an acquaintance. The way she acted just now is how she acts around all my friends. When Dimitri is here when she drops by, I need to wipe down all the furniture because of his drooling. He's asked her out several times. She doesn't ever say no, but she never says yes."

"Can you tell me her room number? I'd like to talk to her."

Landon was not getting it. My sister was only interested in flirting with him. As much as my sister pissed me off, I was protective of her. I didn't want my friends showing up at her dorm room to pursue a relationship I knew she wasn't interested in. "I'm not going to tell you. We need to study Organic, remember? These last few problems are butt kickers."

Sadly, Landon was useless for the last few problems, and I solved them myself. It would have been a lot faster if we had worked together on them, but Landon couldn't stop thinking of my sister. I was sure the vision of her shapely butt covered by her short white skirt was now etched into Landon's brain.

* * * *

The next day, I knocked on my sister's door. Z yelled, "Enter!"

I walked in and said to Z's roommate, "Bella, would you mind if I talked with Z alone for a while?"

Bella shot a look at Z to make sure it was okay, and then said, "Sure. No problem." She carried the book she was reading with her as she left the room.

Once Bella was gone, Z turned to me and said, "Hey, big brother! Great to see you over here in the less desirable side of town." My sister was in a Freshman dorm. "Are you here to keep an eye on me like Mom asked you to?"

I ground my teeth slightly. "I came down here to ask, 'What the hell is going on with you?'"

Z was sitting in her chair with her feet up and her arms wrapped around her legs. As I moved to her bed, she said, "Me? Nothing. Studying my ass off. Engineering ain't no walk in the park. For a study break, I occasionally visit you. I like your friends a lot."

I sat down on the bed. I was so frustrated that I didn't know where to begin. "Why do you always flirt with my friends? You were never like this. What happened to my nerdy little sister?"

Z laughed. "Ah, that. Yeah, you deserve to know what happened. You remember Katharine Newton?"

I smiled. "Of course. She came over all the time." Katharine was a cheerleader who liked working with Z on school projects. She was one of the prettiest girls in my high school with long brown hair and a gorgeous smile.

"She was a big flirter, right?"

"Right. She flirted with me every time she came over. Just a little, but enough to get me revved up. She'd make me feel like she was that close to throwing herself at me."

"Well at the beginning of last year, she went to a party hosted by one of the younger cheerleaders, Kylie. Kylie's big brother Tyler was there, and he was very cute. Becki Davis had met him several times before and was really interested in him. Katharine got to the party before Becki and started flirting with Tyler. Nothing serious as she had a boyfriend, but she enjoys flirting, and Tyler ate it up. Becki got there, and Tyler ignored her to talk with Katharine. Katharine figured out what was going on and left the party early, so Becki could have his attention. The next day at school, Becki was furious with Katharine. They had never gotten along well, and they had lots of little conflicts over the years. They got into a shouting match in front of a lot of people. Eventually, Katharine got kicked out of the football player and cheerleader clique."

"Wow!"

"After she got kicked out, she began hanging out with me. One day, I complained to her that guys were never interested in me because I was so smart in math and sciences, and she said, 'Let's change that'. She did a complete makeover of me. She got me on a cheerleader diet and a cheerleader workout program. She helped me buy a new wardrobe. She got me a new hairstyle," Z swung her hair slightly, "She taught me how to brighten my hair color and what product to use to improve its fullness and shine. She taught me about makeup. She guided me through smile practice."

"Smile practice?"

"Yeah. Sitting in front of a mirror and practicing smiling. For an hour. Everyone in cheer must do it. They have to have a smile on their face for an entire football game. Not smiling when you're performing is a serious no-no."

"So they sit in front of a mirror and smile for an hour?" That sounded worse than watching paint dry.

"Yes. They practice one smile. Katharine taught me a variety of smiles. A happy smile." Z smiled. "A sexy smile." A slightly different smile that did hint at naughty thoughts. "A grin." Another slightly different smile that hinted she was laughing. "The right smile for every moment. You know how I used to hate having my picture taken?" Z used to get pissed off whenever our parents tried to take a picture of her. "It was because I could never make a smile on demand. Now, I can. I was very surprised by what Katharine taught me. It was like there was a whole world of practical knowledge that the cheerleaders kept a secret from the non-cheerleaders like me."

I had to admit that my sister was very attractive now. I had never paid much attention to how my sister looked until she started flirting with my friends, but I had known vaguely last Christmas that she had lost weight and looked better.

"And she taught me how to flirt. Katharine loves flirting and was thrilled to have an eager pupil. She had me practice initially with Becki's boyfriend. I never got him to break up with her, but I made Becki so angry. She'd tear into Katharine before or after practice, and Katharine would pretend she didn't know what Becki was talking about. I eventually flirted with a guy I really liked, and he asked me out. I was so excited."

"Brett?"

"Someone else. And then I learned the downside to flirting. He never took me seriously, even though I was one of the smartest people at our school. It was like flirting made me a bimbo in his mind, and I could never overcome that stigma. I eventually dumped him. Brett started giving me attention. Katharine coached me through how to encourage him, but not encourage him too much. He eventually asked me out, and I had a good time dating him. He always treated me how I wanted to be treated."

Brett had seemed like a nice guy. I had assumed her losing weight, wearing prettier clothes, and having a new hairstyle were due to Brett. When she broke up with him just before going off to college, I had expected her to revert to her pre-Brett self.

"Great. You know how to get a boyfriend. Now, go get one and stop flirting with my friends."

"I'm working on it. I'm getting to know my classmates. My classes are so huge that it's taking a while. The guys who talk to me now are aggressive jerks. It takes a while to get to know the type of guy I want to date."

"Fine. Flirt with your classmates then instead of my friends."

Z shook her head. "No."

"No?"

"No."

"Why not?"

"Two reasons. First, if I flirt with a nice guy that later I want to date, he's never going to respect me because I flirted with him first. Second, flirting can turn scary if the guy takes it as a message that I'm a slut he can use as he wants. I need to have someone close by that I trust to get me out of a scary situation."

My stomach suddenly dropped. I could see what Z was leading up to.

"Your room is the only place I feel safe to flirt," she continued. "I know your friends are going to be nice guys, and you're there in case anything goes wrong."

This was not how I expected this to go. Z had me on the defensive now. "It could still go wrong. They could accost you in some hallway when I'm not around."

Z arched an eyebrow. "Did you tell Landon that I wasn't serious when I flirted with him? Did Landon ask for my room number, and you refused to give it to him?"

I clamped my teeth together. It was like Z could see right through me. I felt like I was losing this fight. "So, you're taking advantage of the fact that I'm a good big brother?"

Z got up, sat down next to me on the bed, and put her arm around my shoulders. "You're right. I am taking advantage of the fact that you're a great big brother." She was speaking slowly; her voice full of honesty. "I know you'll do your best to take care of me. As much grief as I've given you about Mom telling you to look after me, I'm glad that you are. This big university is a scary place for a girl not raised in the city." Our town was the biggest for miles around, yet it was only modest-sized. "I know I should have asked about this before, but I thought you would say no. Would you please let me flirt with your friends when I'm with you?"

"I don't think it's a nice thing to do to my friends."

Z smirked. "You don't think Landon enjoyed my flirting with him? Do you think a pretty girl had ever flirted with him before?"

I didn't say anything, but we both knew from Landon's reaction that he had never had a pretty girl walk up and flirt with him like Z had done.

"Landon seemed like a nice guy," Z continued. "I'm sure he'll marry some wonderful doctor someday, but I doubt she'll be as pretty as I am. I gave him a thrill he'll remember for the rest of his life."

I thought back over Landon talking to me. He had been thrilled. I had warned him, and I still had to talk him down after Z had flirted with him. He hadn't been angry. It was like...for a few minutes he had been like a movie star or a high school quarterback. It had been an emotional high that I could see him not forgetting.

As for him marrying a fellow doctor, doctors had by far the highest rate of intermarriage. There were some nice-looking girls in our classes, but none who could hold a candle to Z. As Landon was average-looking, he'd probably date average-looking pre-meds and then average-looking med students, and eventually marry an average-looking doctor. He knew it as well as I did. So, Z was indeed probably the prettiest girl who'd flirt with him in his life.

Had any of my friends been angry with Z at any point? None that I remembered. All of them had similar reactions as Landon. The few she had flirted with multiple times had been just as eager to flirt with her the later times as they did the first time.

"Your flirting is great for you, and I have to agree that my friends seem to enjoy it, but it really sucks for me. You left Landon so distracted that he was absolutely no help on the Organic homework. I had a huge amount of homework yesterday and stayed up later than I planned to get it all done."

Z said in almost a little girl voice, "Do you like me visiting you? You never come here to visit me."

I closed my eyes and ground my teeth. Now she was making me feel guilty. "Yes, I like you visiting me. I like seeing you're doing okay. I never come to visit you because I'm always up to my eyeballs in schoolwork. I wish you'd visit me when no one else is there."

"That'd be so boring. You know I'm normally a terrible conversationalist. It's a lot more fun visiting you when you've got friends over. It didn't take me very long to figure out when you were most likely to be studying with a friend, and that's when I dropped by to let you know I'm doing okay."

"And to have fun flirting with my friends."

Z laughed softly. "True. But not just fun - I did enjoy talking with Landon. All of your friends are nice guys."

This was so frustrating. Z wasn't getting how much of a pain her visits could be. "I'm glad you think my friends are nice, but there are times when I don't want you flirting with them, like yesterday."

Z nodded. "How about this - when I come in, if you rap twice on your desk, I'll not flirt and leave as quickly as I politely can?"

I thought that over. "That'd be fine." Even though Z drove me nuts at times, we got along well. I respected how hard she worked and how smart she was. I felt like she looked up to me, which made it hard to be mean to her or tell her no.

"Great!" Z gave me a big hug. "Thanks, Eli, for being so understanding."

"As you never tell me anything when you come to see me, how are you doing?"

"Doing great. I'm acing all of my classes."

"How do you like Bella?"

"She's okay. Not a friend, not annoying."

Now that Z had gotten what she wanted, she was back to her usual non-chatty self. Her giving short answers to my questions was pretty typical of her, which made her flirting even more unusual. "Speaking of Katharine, have you heard from her recently?"

"I text her all the time."

"Tell her I said 'Hi'. How's she doing?"

"Doing fine. Driving the guys at her college crazy."

"Have you heard from Brett?"

Z shook her head sadly. "He was really upset when I broke up with him before I left for college. He wanted to keep dating."

"How did--"

"I don't want to talk about him."

"Okay." I felt drained from our conversation, so I decided to leave. "I need to get back to studying." I gave Z a side hug and then stood up. "Please visit often. I do enjoy seeing you. Feel free to join me and my friends for lunch or dinner."

"I'll do that."

* * * *

Once Eli left, Z pulled out her phone and started texting with Katharine.

Z> E talked to me. He doesn't like me flirting with his friends

K> He's jealous you don't flirt with him

Z> K! He's my brother!

K> Guys hate it when a girl flirts with everyone but him

Z> He didn't like that I was distracting his friends from studying

K> But they study all the time!

Z> LOL! I know. I promised not to flirt when he has to get some studying done
K> You'll have to be bolder when you do flirt

Z> I'm so bold now

K> You can be a lot bolder. Show them your boobs!

Z> Stop it! You're so evil

* * * *

A few days later, my roommate Dimitri and I were comparing how we did on our first major exam when Z dropped by. She was wearing a dark blue short skirt and a white shirt that was almost like a gym shirt; a thin amount of material on her shoulders and lots of open space around her armpits. I could see on top the straps of her black bra and through the arm holes the sides of it. When she came in, she went straight to Dimitri. "How'd you do on your test?"

"Very well," Dimitri said with his heavy Ukrainian accent. "Better than your brother."

"That's wonderful!" Z gave Dimitri a little hug. "You'll be a great doctor someday. And I'll be able to say I knew you back when you were a lowly pre-med student. Have you told your parents?"

"No. I will talk to them middle of next month." It was late September. "I do not talk to them about the good tests, so I do not have to talk to them about the bad tests."

"Well, you can talk to me about the good tests. I take it that it was very hard."

Dimitri told her about the test; how many of the questions were very tricky, and that you had to know the material inside and out. I could tell he was eating up Z paying attention to him.

After they had finished discussing the test, Dimitri said, "Z, I would like for you to do something."

"What's that?"

"On Friday, I will have some friends over to watch a movie. An old action adventure. We drink a little bit, we make fun of the stupid things in the movie, and we have a good time. Would you please join us?"

"Oh, I thought you were going to give me a present." Z winked at Dimitri like she was joking. She then looked at me for confirmation I'll be there to have her back.

"I'll be there. Landon should be there. You've met Rob. He should be there too."

Z said to Dimitri, "I would love to join you. What time?"

"Nine." Dimitri turned and opened a drawer in his desk. "And I do have a present for you." He pulled out a box and handed it to Z.

"Victoria's Secret? You shouldn't have."

Victoria's Secret? What the fuck? Why was my roommate buying lingerie for my sister?

"Bah!" Dimitri waved away Z's protest. "My parents give me lots of money. They will be happy to know I spend some on a pretty girl."

Z gave Dimitri an indulgent smile. Dimitri handed her a pocket knife, and she opened the box. "A bra," Z said as she lifted it out of the box.

"34C. I remember. Blue, like the color of your eyes." He took the box from Z. "Try it on. If it not fit, I will send it back and get one that does."

Z looked at Dimitri like she was struggling with whether she should accept this present or not. I hoped she wouldn't. She had dropped a hint earlier about Dimitri buying her a present, but a bra was not what I was expecting him to give her.

To my disappointment, Z said, "Okay." She turned and went to our closet, opening its door. I assumed she would go in it and change, but, instead, she hung the new bra on the outside doorknob. She grabbed her shirt and pulled it over her head while her back was to us. She reached up and hung the shirt on the top of the closet door. Once her back was to us again, Z reached behind her and undid her bra. I turned to Dimitri, and his jaw had dropped. From the way he looked, I wondered if I was going to need to perform CPR on him.

Z's breasts were bare, and I could see the tiniest amount of side boob as she swapped bras on the doorknob. I was outraged by Dimitri giving her the bra and her now putting it on in front of us, but, at the same time, I couldn't turn away from watching her. Z's upper half did look great. She quickly put the new bra on. She spent a few moments tugging and pulling. "The material feels nice. Very good construction. Fits me well." She grabbed her shirt, pulled it on, and then turned to face us. "Thank you, Dimitri." Z walked over and gave him a gentle kiss on the cheek. "It was sweet of you to give me a present."

"Okay." Dimitri looked very happy. Z's little show had been well worth his money.

Z put her old bra into the box. "Gotta go. I'll be here Friday at nine. Bye!"

"Bye!" Dimitri and I said.

Once the door was closed, Dimitri turned to me and said, "What a woman!"

"What the hell, Dimitri! Why did you buy her a bra? Why didn't you buy her something more reasonable, like a box of chocolates?"

Dimitri chuckled, which pissed me off even more. He then tapped the side of his head with his finger. "My father told me once to always be sure that the person you are giving a present to wants whatever you are giving them. Nothing offends more than giving someone a present they do not want. It tells them that you have not paid attention to them."

"What does this have to do with buying my sister a bra?"

"You said I should have bought her a box of chocolates. I thought of that. But then I remembered when she eats with us, she never eats a dessert. She eats low-calorie food to keep her weight down. She never talks about it, but she does it. She would not want a box of chocolates."

I had to admit what Dimitri said made sense. "You could have bought her a Diet Coke."

Dimitri laughed and shook his head. "I have too much money for that to be a good gift. It would be another insult." I could see that. "I thought of buying her a bottle of excellent vodka." He let that hang for a few moments.

"But she doesn't drink vodka."

"I thought of a bottle of wine."

"Same thing."

"I thought about perfume, but I don't know what perfume she likes or even if she wears it. Then I thought about a shirt. She has so many funny shirts. But I don't know what she would think is funny. I don't know her size." He tapped the side of his head again. "But I knew the size of one piece of clothing she wears. She was quite proud when she told me. So why not? And she liked it." A beatific look filled his face.

I wanted to punch Dimitri in the stomach. It always annoyed me when Z ignored me to flirt with my friends, but today really, really upset me. "Doesn't it bother you that she's just flirting with you and isn't interested in you?"

"She likes me." Dimitri smiled widely. "She would not ask so much about my test if she did not like me. She does not like me as a boyfriend. She likes me as a man." Dimitri stood up. "When she told me I would be a great doctor someday, she made me feel like a big man." He puffed up his chest and swung his arms in front of him in an exaggerated motion as he marched around the room for several steps.

"You know, instead of flirting with Z, you could hook up with one of the women in our classes."

Dimitri sat down. "Bah!" he said while waving his arms dismissively. "The females in our classes are not women. They are like you and me, except they have no penis. They do not know how to make a man feel like a man." He pointed in the direction of our closet. "When she took off her shirt and bra, I saw one of the most beautiful sights in the world. If one of the females in our class took off her clothes in front of me, I would say to put them back on." He held up his hand as to block the view. "I would not want to see that."

"Several of our classmates look good naked." I knew from personal experience.

"But they do not know how to make me want to see them naked. It would be like a patient visiting me as a doctor. 'Doctor Dimitri, I have removed my clothes. Let's start the procedure.' When Z had nothing on, I wanted to beg her to turn around. I wanted to drop to my knees and beg her. I did not because I knew she would not turn around even if I begged." Dimitri turned pensive for a few moments. "I am glad she does not like me as a boyfriend. I would be a bad boyfriend. Study too much. She deserves to be taken out to the best restaurants all the time. I would not be able to do that. I am happy to be her friend. She is a very good friend to me." Dmitri smiled broadly. "She knows how to make me very, very happy."

* * * *

Friday night at nine, Z came into our room. She was wearing shorts instead of her usual short skirt. She was wearing a T-shirt that she had cropped about six inches below her breasts.

"Hey, Z," I said. "Come on in. I don't think you've met Vivek." She shook hands. Vivek's eyes were mostly on her top. The material in front dropped straight down from her bust line, and the gap between her shirt and her bare stomach emphasized how much her breasts stuck out from her chest.

I walked over to the door and locked it. "You can serve the drinks, Rob." Having alcohol in the dorms was very forbidden, so we didn't start drinking until everyone was there. I didn't know how Rob got the liquor as he was nineteen. But as his parents were both doctors, he had the money to acquire liquor, laws be damned.

Landon's parents were also both doctors. Dimitri's parents were wealthy Ukrainians. I knew very little about Vivek's parents other than they were immigrants.

Rob said, "Tonight's drink is rum and coke." Every movie night, Rob served up a different mixed drink. Landon had brought several food platters. Vivek had some food delivered from Domino's. As the poor mouse of the group, I had contributed only a couple of bags of chips.

I took a plastic cup from Rob and handed it to Z. "We only drink enough to get buzzed. Nobody gets drunk. Eat as you drink. Don't be afraid to ask for straight coke."

Rob added, "And if I think anyone is getting drunk, I'll give them straight coke."

Dimitri had a workstation computer with a huge monitor which was what we were going to watch the movie on. I sat down in the middle of my bed, so I had to turn a little to my right to see the movie. Z sat down to my left, between me and the wall. Once everyone had a drink and some food, Dimitri said, "Tonight, we watch the Stallone movie, 'Cliffhanger'. Have any of you seen it?"

None of us had. It was normally at this point that Vivek asked if there was any nudity in the movie. He didn't tonight. He was standing to Z's left. I said, "Vivek, you can't see the screen very well from there. Go sit at my desk." He seemed reluctant to give up his proximity to Z but eventually made the move.

The first scene was a downer as a friend of Stallone's slipped out of his hands and fell to her death. Then the movie had a long mid-air heist scene that we hooted and howled at. Dimitri stopped the movie several times during that scene so we could talk at length about how stupid it was. "The air traffic controllers really don't notice a plane pulling alongside another plane?" "Don't they realize that when a plane is flying at 500 mph, that means the air is blowing outside at 500 mph?" We are all laughing so hard at how fake and stupid it was.

Z was mostly quiet. She made some comments to the bad guy's girlfriend - "He's going to throw you under the bus!" - but not much more. However, her presence changed the atmosphere. Nobody used any bad language. When one of my friends made a good joke, he'd look to see if Z laughed. The quality of humor and conversation seemed better; like the guys were trying their best to impress her.

It was close to midnight when the credits started. After I helped clean up for a bit, I said, "I'm going to walk Z home."

Z said, "Dimitri, thanks for inviting me. I had a great time."

"We will watch another movie tomorrow night. Do you want to join us?"

"Sure. Should I bring something?"

"No," was the response from all the guys except me. Dimitri added, "We have too much as it is."

"Okay," said Z. "See you tomorrow night."

When Z and I got into the empty elevator, she asked, "You didn't want me to flirt with Vivek?"

"Correct. I was afraid he wouldn't accept my telling him you weren't serious." Z nodded. "Did you have a good time?"

"Yes. I've never hung out with a group of guys before. When I hang out with a group of girls, the conversation always moves faster than I can keep up with. It's very frustrating. I'm a nerd. I do fine one-on-one, but I've always floundered in groups. But I didn't feel like I had to be funny or entertaining tonight. I felt like your friends just wanted me to hang out with them. And that was really nice."

We were in the lobby now and making our way out the door. We didn't say anything in the public area, but we resumed our conversation once we were outside. Z asked, "Do you not like Vivek?"

"Vivek is okay. He tells a lot of jokes, but I don't find his humor funny. But Landon, Rob, and Dimitri do. And he wants to watch movies with us, whereas most of our classmates want to do other things on their weekend nights."

"Why don't you find his jokes funny?"

"Most of them are about his parents pressuring him to succeed. They call him whenever he gets a test back and demand he explain why he didn't get a 100. A 99 isn't good enough for them. Landon, Rob, and Dimitri are under huge pressure from their parents. Come back with a near 4.0 or don't come back. They find his reenactments of his parents' phone calls hilarious. I don't because Mom and Dad don't pressure me that way."

When we approached a park bench, Z said, "Let's sit for a bit." Once we were seated, she asked, "You don't feel pressure from Mom and Dad? You're living their dream. You can't expect me to believe there's no pressure."

My parents had been pre-med majors at this same university. Both had come oh-so-close to making it into med school, but an inch is the same as a mile when you don't make the cut. Mom continued pursuing her dream of helping patients and became a physician's assistant. Dad had become a pharmaceutical sales rep. Dad had been a year ahead of Mom in college, and though they had known each other during their college years, they had never dated and hadn't kept in touch after Dad graduated. But they had kept in touch with a mutual friend. When Dad got transferred to the city where Mom was living, the mutual friend suggested he get in touch with her. And the rest is history. When I was born, my parents moved to my mom's parents' town so my grandparents could help watch me. Dad now taught high school Biology and Chemistry.

"The pressure they've put on me is to bail on pre-med. They wanted me to go into engineering."

Z's eyes went wide. "I didn't know that."

"Publicly, they support my decision to go pre-med. Privately, they tried to talk me out of it. They know how much of a gamble pre-med is, how hard you have to work, and how disappointing it is to come up short. But it's my dream, and I think I can make it."

Z brightened. "And I think you can make it. Dimitri, Landon, and Rob think you can make it. I can tell by the way they talk to you."

I smiled. "Thanks." That made me feel good. "You don't have to come to the watch party tomorrow. You can hang out with your classmates or dorm friends."

"I much prefer hanging out with you and your friends." She paused for a moment. "I have a tough time reading people here. I'm used to being with friends I've known for a long time. When I'm with you and your friends, I use you as my reference. I could tell not to flirt with Vivek because of how you acted. I knew it was okay to accept drinks from Rob because you gave your okay. I can use you to triangulate their responses. When I'm in my classes or my dorm, I have no idea what people think of me. I'm a quiet wallflower."

"Z..."

"And I want to get better! I want to learn to read people better. I want to learn how to say witty things in groups. And I can learn those things much faster hanging out with you and your friends. I didn't just have a good time tonight; I grew as a person. So I definitely want to attend tomorrow."

Having had her say, Z stood up, and we continued to her dorm. When we got there, she said, "Thanks for the wonderful evening."

"Thank Dimitri. He's the one who invited you."

"I only went because you'd be there. I only drank because you were there. I only felt safe enough to relax and enjoy myself because I was sitting next to you. You are why I had a wonderful evening. Thanks."

That made me feel warm all over. It had been a great night for me as well, mostly because of my sister.

Z turned and walked into her dorm. I watched her until she got into an elevator. I hadn't gotten along with my sister in high school. We had fought, although not that often. Once I started dating, I was grumpy when I spent my free time with her because that meant I wasn't spending my free time with a girl. She had had her friends and her life, and I had had mine. I hadn't really cared or thought about her.

I cared and thought about her now.

* * * *

Z> I'm back

K> How was the party?

Z> Fun. Relaxing. I was buzzed most of the time

K> Pot or booze?

Z> Booze

K> How many guys were there?

Z> Five, including E

K> How many did you flirt with?

Z> None. I can't flirt with a guy in front of other guys

K> Sure you can. It's great fun! You can get them all eating out of your hand

Z> You can

K> You can too. I'll teach you

* * * *

Every weekend, Z attended both the Friday and Saturday movie-watching parties. Dimitri and I were always there, the rest missed occasionally. Z steadily found her voice. Her little niche was making fun of the female characters who did little but scream and need to be rescued. When there was any nudity, she'd tell us what she thought how many stars the sixteen-year-old boys who watched the movie in the theaters would give that scene. And she'd flirt with the guys. Landon had traveled a lot, so when there was a scene in some city or country that Landon had been to, she'd say, "Let's ask our international traveler if that was accurate." Rob was a big history buff and also was a rock climber. She would play those up when she could. She even flirted a little with Vivek, calling him "Big B". Vivek's last name began with 'B', and there's a famous Indian actor who goes by "Big B" that Z said Vivek looked like a younger version of. How she found out about that I had no idea. Dimitri is 6'1" - the same height as me - but he's much wider than me and built like an offensive lineman. She'd tell him he could have done that action scene better than the puny male star.

And then it was the last movie-watching party before Thanksgiving break. Vivek wasn't there. School was closed for all of Thanksgiving week, so there'd be two weekends with no movie-watching party. As we were getting our drinks and food before the start of the movie, Landon asked Z, "What is your first name? I've wondered since I met you."

"It's a nice but boring name. I much prefer Z."

Rob said, "We like calling you Z. It's a cool nickname. But we'd still like to know your first name."

"If I tell it to you, you'll think I'm stupid for not using it."

The guys opened their mouths to protest. But before they could say anything, Z waved her hand in front of her to silence them. She asked, "Do you promise to not tell anyone?"

"Yes!" they all said.

"Okay. It's Emily. I'm Emily Annette Zajaczkowski. When I was in kindergarten, there were two other Emilys. The school policy was when there were multiple kids with the same first name to call each student by their first and last name. But no one could pronounce my last name, so I was Emily Z. My classmates eventually dropped the Emily and just called me Z. I liked Z because there were so many Emilys, but there wasn't any girl who used just her last initial as her name. I've gone by Z ever since. That's my story. Pretty silly, huh?"

The guys took turns saying nice things about my sister. "Emily is a pretty name."
"A pretty name for a pretty girl."

"Z suits you better. It's a little mysterious and definitely unique."

"You are unique, Z."

"Unique. And wonderful."

"Definitely wonderful."

"Hear! Hear!" said Landon. He raised his plastic cup. "To Z, who is wonderful and unique. We all vow that her first name will never pass our lips again."

Everyone raised their drink and said, "Hear! Hear!" We all drank in her honor.

Z was blushing. She was obviously touched by all the nice words. "And all of you are unique and wonderful. Big group hug." She grabbed my arm and pulled me into the hug. We hugged each other for a good 20-30 seconds.

Normally, we were very harsh on the movie, ripping it with all the gusto we could. But not tonight. It was like all of us were too happy to think of something mean to say.

* * * *

Thursday, Z dropped by in the afternoon. With the cooler weather, she was dressed in jeans and a long-sleeved T-shirt. As usual, she went straight to Dimitri. "Good luck on your tests tomorrow."

"Thanks."

Z said to me, "And good luck to you too."

I rolled my eyes. "Thanks for noticing I still exist."

"I know you exist. You're driving me home tomorrow as soon as I'm done with my last class." Z turned back to Dimitri. "Excited about seeing your parents?"

"Yes. We will have a good time in San Diego. Did you get back your Calculus test today?"

"Yes." Z brought her hand to her face and gave Dimitri a shy look.

"How did you do?"

"Oh, I got a 100."

Dimitri smiled widely and said to me, "Your sister is smart. Very smart. And a very good student." Dimitri opened a desk drawer and pulled out a box. "Such a good student deserves a reward."

Z put her hand on her hip. "Dimitri," she said in a mildly scolding tone, "One present was more than enough."

"I will see you only a little bit tomorrow before I leave for my flight, then I will not see you for nine days. I give you something to remind you of me while you are away."

Z gave him a mildly displeased look, and then said "Okay," as she reached for the box. "Victoria's Secret again." She sat down on my bed. The tape on the box had already been cut through, so Z quickly opened it. She pulled out a bra that was black with white polka dots and held it up for a moment. "Nice pattern". She set it next to her and pulled out of the box a pair of panties with the same pattern. She held them up longer, inspecting them. "Not much material." They had a decent-sized triangle in the front, but a tiny triangle in the back. She put the panties back in the box and held the bra up for a longer inspection. Its back looked something like a sports bra. "Look at the cups," she said to Dimitri. "They have less material than usual. It'd show off a lot more boob than a normal bra would." She put the bra back into the box, stood up, and faced Dimitri with her hand on her hip. "Do you think I'd wear lingerie this revealing?"

Dimitri couldn't meet Z's gaze. As he was looking down, he said, "They looked very nice on the website."

Z arched an eyebrow. "What would your parents think of you buying your roommate's sister such sexy lingerie?"

Dimitri looked proudly at Z. "If they knew how much my roommate's sister makes me want to study - I must do well on my next test so I can make Z smile when she asks my test score - they would tell me to buy you everything for sale at Victoria's Secret."

Z smiled, accepting defeat. Z took the box and walked toward the closet. I watched to see if she'd do a reprise of the last time she tried on a bra from Dimitri, but she went into the closet this time. I looked at Dimitri. He looked disappointed. He gave me a shrug. I was surprised to find that I too was disappointed. I knew the show would have been for Dimitri, but I would have gotten to watch. It had been a while since I had seen a girl half-naked, and my sister had a nice body. Not that I was checking out my sister or wanting to see her half-naked. Okay, I did want to see her half-naked, but I didn't WANT to see her half-naked.

I had gotten over my jealousy of Z flirting with my friends. Yes, part of me still wished she paid more attention to me when she dropped by for visits. But it was me who got to have long talks with her as I walked her back to her dorm after movie nights. What my friends got was flirting and no conversations of real substance. It was like Z was keeping them at a particular emotional distance. I got to see the real Z while my friends only got to see Z in her flirting mode. I liked the real Z, and our conversations at the end of movie nights were the highlights of my week. My friends were jealous that I was the one who got to walk Z back to her dorm and not them.

The closet door opened, and mine and Dimitri's heads whipped in its direction. Z jumped out from behind the door, facing away from us. She was wearing only the panties and the bra. The panties were basically a thong, with a small triangle of fabric at the top of her ass crack. We could see all of her well-rounded ass. The bra showed off her lean, long back. Z wiggled her butt for a few seconds and then jumped back behind the closet door. We heard her laugh as she closed the door.

Dimitri and I looked at each other stunned. Had we really seen that vision of feminine beauty? Neither of us could believe that Z had done what she did.

We both sat in our desk chairs in silence. A minute later, the closet door opened, and Z walked out in her jeans and T-shirt, carrying her shoes. She gave Dimitri a saucy grin. "They fit. Thank you, Dimitri." Dimitri didn't respond. I guessed he was still in shock. "So, what are you going to do in San Diego?"

Dimitri shook his head as to clear his thoughts. "I do not know. My mother sent me the airplane ticket Monday. That is all I know."

Z was tying her shoes. "I've never been to San Diego. The pictures I've seen are very pretty. They have a great zoo there. I'm envious." She chatted with Dimitri for a few more minutes. "Be here when I come over after my classes. I want to say goodbye to you."

"And I want to say goodbye to you."

Once she was gone, Dimitri turned to me. "I tell you a secret. You no tell Z, okay?"

"Okay."

"My parents are bringing my girlfriend with them."

"You have a girlfriend?" Dimitri had never mentioned a girlfriend before.

"Sofia. She was my girlfriend before I leave for college. When I leave, I say goodbye to her. I do not expect to see her again. Last October, my parents tell me we are going to Disney World in November, and Sofia will be there. We had a good time. It was like I never said goodbye."

"Why didn't you tell people about her?"

A pained look came across Dimitri's face. "My life is in America now. I go to med school. I become an American citizen. Why not marry an American? But my parents want me to marry a Ukrainian. Sofia's father is my father's biggest customer."

"And your parents are paying for your college..."

"My parents pay for everything." Dimitri made a sweeping gesture. "I tell them what I told you about our female classmates, they are happy and give me money. When they see me with Sofia, they are happy and give me money. If I told them about Z, they would be very unhappy."

"And if they are unhappy, they may stop giving you money."

Dimitri nodded. "If I marry Sofia, her whole family can move to America. Things are very unstable in Ukraine. No one feels safe. Much better to take what money you can and move to America. If my parents tell me in San Diego that I must marry Sofia, I will marry Sofia. And she will be a good wife." Dimitri let out a sigh. "But this time when I am in bed with Sofia, I will be thinking of Z."

Z> What?

K> A favor for a friend. E will enjoy it

* * * *

I got a text message from Z: On my way. Will say goodbye to Landon and Rob before going to your room

I checked once again that I had everything packed. I didn't like having nothing to do. The adrenaline was still pumping through my body from the back-to-back tests I had taken. I felt I had done well, but I wouldn't know for over a week. I thought about starting a conversation with Dimitri, but I couldn't think of anything to say. We had already discussed how we thought we had done on our tests. He didn't know anything about what he would do in San Diego, other than boink Sofia. He was packed and would catch a ride to the airport in fifteen minutes. He also looked too pumped up to do anything but wait for Z. He kept looking at the door longingly.

Dimitri finally asked me, "What is there to do in your town?"

"Not much. See friends. Go to Walmart and do my Christmas shopping. Put up Christmas decorations. I won't be spending a huge amount of time with my parents as they will be working Monday, Tuesday, and Wednesday." The school district was off only Thanksgiving and Black Friday. "The doctor my mom works for will be on vacation the whole week with his family, so my mom will be seeing all of his patients. Z and I will take care of his house while he's gone. Seeing friends is the most interesting thing."

"You go ride horses? You shoot guns?"

I laughed. "No, nothing like that. Our neighborhood is a lot like the neighborhoods around here. Just fewer businesses to drive to." I checked my phone. It had been a while since Z had sent her message. She was taking her sweet time saying goodbye to Rob and Landon.

Then Z came in through our door. She was wearing a royal blue tank top with spaghetti straps and bright purple leopard print leggings. I had seen neither before. They didn't really go together. Z normally dressed with better style than that. She dropped her bags by the door.

Z went straight to Dimitri. "All set for your trip?"

"Yes. You have a good time with your parents."

"And you have a great time in San Diego." Z dropped the pitch of her voice. "You know Dimitri, you're very special to me." She reached up with her right hand and grabbed the left spaghetti strap. "I'll miss you a lot these next nine days." Z pulled the spaghetti strap down, so it was down on her arm. Her eyes were locked on Dimitri's as she did so. The black strap of her bra was now clearly visible as well as the top of the cup. It was the bra Dimitri had given her yesterday. Z said huskily, "I'll think about you all the time while I'm alone at home." She grabbed the bra strap and pulled it to just below the top of her shoulder. "Poor, poor me all alone in my boring hometown." She pulled the bra strap down next to the spaghetti strap. "I want you to think about me while you're in San Diego." Dimitri had a deer-in-the-headlights look as he stared at Z's upper left chest. Z said even more sultrily, "Promise me you'll think about me in San Diego." She pulled the spaghetti strap down further, exposing more of her bra.

Dimitri stood there as if he was made out of stone for a few moments, and then he said, "Yes, yes. I will think about you."

"Wonderful." Z stretched the word out, filling it full of promise of reward.

Z moved forward and hugged Dimitri. As she did so, she used her left hand to deftly pull her bra and spaghetti strap back into place. I was amazed at how she could expertly maneuver the two straps without looking at them.

Z pulled back from the hug and turned toward me. "Ready to go?"

"Been ready for a while."

I grabbed my two bags and headed toward the door. When we got close to the door, Z turned back to Dimitri. "Remember your promise."

"I will think of you, Z. All the time. All...the...time."

Z gave him a sultry grin and then turned, grabbed her bags, and joined me in heading out the door.

The last glimpse I had of Dimitri, he looked dazed and confused as he waved gently to us.

* * * *

When we got in the elevator, Z said, "I can't believe I did that. Man, my heart is pounding. That was so crazy."

"That was quite a goodbye."

Z shook her head in disbelief. "It was all Katharine's idea. I can't believe she talked me into doing it. That was so over the top."

I smiled. "It was."

"And that was the least scary one. I gave Landon and Rob the same goodbye."

"You did?"

The elevator doors opened, and some students got in. Z and I were quiet until we got outside my dorm. Z reached into one of her bags and pulled out a jacket. Once we were away from the other students, I asked, "You gave Landon and Rob the same goodbye?"

"Yeah. I've never flirted with them before without you around. I was terrified they wouldn't let me pull away from the hug. But they did."

We hiked in silence for a while. I was absorbing that Katharine had pushed Z to give such a dramatic goodbye to my three best friends. What else had Katharine pushed Z to do?

I said, "It's a little cold for that outfit." I couldn't resist adding. "And it's a pretty wild combination."

Z smiled at me. "Landon gave me the top Tuesday, and Rob gave me the leggings Wednesday." I laughed. "I was afraid my roommate would say something to Rob about Landon's gift."

"And you're wearing the bra Dimitri gave you yesterday." I couldn't help grinning. "Are you wearing the panties too?"

Z looked down in embarrassment. "Yes. I don't like how they feel, but Katharine told me I should get used to that style of panties. So, I'm giving them a try."

"If you don't like how they feel, why wear them?"

"Katharine said guys love it when a girl wears these type of panties."

"How will they know what type of panties you're wearing?"

Z looked away embarrassed again. "What they will notice is the lack of a pantie line when I wear yoga pants."

"But you don't have any yoga pants."

"Katharine is giving me some this week as an early Christmas present." After a couple of beats, Z added, "When we were discussing what I'd do for my goodbye, she suggested that, while I was hugging Dimitri, I whisper into his ear that I was wearing the panties he gave me. I felt that was too much."

Oh, God. I could only imagine what that'd do to his heart rate. I had to admit that talking about those panties had me thinking of how fine Z's ass looked in them. "You shouldn't have modeled those panties in front of me."

"You're right. I screwed up. I'm sorry. Katharine and I had talked about what I should do if Dimitri gave me a bra and pantie set, and what I did was what we had agreed on. I had assumed the panties would be normal, and what you'd see was like me wearing a bikini. I didn't adjust the plan for the type of panties he gave me. I should have gone with what I did when Dimitri gave me the bra."

I was surprised by these revelations. "Was that also something Katharine told you to do?"

Again, Z looked embarrassed. "Yes. She prepped me for receiving different types of presents. I thought she was crazy when she brought up the idea that one of your friends would give me a gift. And then Dimitri gave me the bra, and I just followed what Katharine had told me to do."

We arrived at my car. We threw our big bags into the trunk and our small bags into the back seat. I started the car, and we were off on the three-hour drive home.

Z said, "It's really funny. Katharine is the first close female friend I've had since I was ten. I had assumed we'd drift apart when college started, but we've grown closer. We talk all the time. She loves that I'm flirting with your friends. It's what we talk about the most. Last night, we spent an hour on video chat; Katharine watching me as I practiced saying goodbye in front of the mirror. Everything I did was Katharine's idea; what I said and how I said it. I did it over and over until she was satisfied that I had it down perfectly. And we cracked jokes the whole time. It was a lot of fun. I'm looking forward to spending a lot of this week with her."

* * * *

Once the conversation between Z and Eli died down, Z pulled out her phone.

K> How did it go?

Z> I nailed it all three times

K> And how did they take it?

Z> All three's eyes were HUGE as they promised me they'd think of me

K> Hehehe

Z> It was like I was breaking their hearts

K> You were, girl. Did L and R behave?

Z> Yes. It was so scary with them

K> You have your guys trained well :)

Z> I still can't believe you talked me into doing that

K> You loved it. Admit it

Z> My heart was pounding after each goodbye

K> Of course. That's part of why you loved it so much

Z> You're so evil

K> Just talking you into doing what you want to do

Z> Next time, not so crazy. Okay?

K> Well see. Have you talked to E about Sunday yet?

Z> No

K> Do it. He's vital

Z> What are we doing?

K> Sleepover at your place. G and maybe some of her friends

Z> So why E?

K> I want to do something nice for G. E is a part of that

Z> What?

K> Not sure yet. G wants everything and wants nothing

Z> That must drive you nuts

K> It does. It reminds me why you're my BFF

Z> :)

K> Talk to E. Get him to agree. Tell him I promise to give him a big kiss when it's done

* * * *

When Z set her phone down, I asked, "Texting Katharine?"

"Yes."

Z didn't seem to want to discuss it, so I asked, "Are you interested in dating Landon, Dimitri, or Rob?"

Z perked up. "Oh, no. I don't want to date them at all. It'd be a disaster if I dated one of them."

"How so?"

"In two ways. First, I'd be a big disappointment to them. When I talk to them, I'm this flirty, confident, aggressive girl. I enjoy being that way, but I can only keep it up for a little while. And then I'm back to quiet, nerdy me. Everyday me isn't who they want to date."

"They might."

"Even if they did, there's problem number two. If I started dating one of them, then my friendship with the other two would fall apart. I don't want that. I really enjoy being friends with all three of them. I love flirting with them. They're my guys, and I'm their sweetheart. I struggled for a while to come up with what I am to them. I've decided I'm their sweetheart. Someone they like and who is very special to them, that they have some desire for, but who they'll never date."

"You think it'll work long-term that way?"

"I hope so." Z twisted in her seat. "You know what really endears them to me?"

"What?"

"That they ask how I'm doing on my tests. I see how hard you four study. In high school, it was always implied that I should let the guys get the top test scores. It hurt their egos that a girl was besting them. With my guys, they're always pushing me to do my best, to get a hundred on everything. I loved being pushed. I want to be the best damn engineering student at our university, and I may make it with their encouragement."
That made me feel warm all over. I respected how Z knew what she wanted and was eager to go after it. She had her weaknesses, but she was working hard on improving them. There was a fearlessness to her.

Z added, "There are a few guys in my classes and in my dorms who I've gotten friendly with. I can't imagine dating any of them either. If I had a boyfriend, then things would fall apart with my guys. If one of my guys got a girlfriend, I'd stop being their sweetheart. I'd start seriously flirting with one of your other friends and try to convince them to join the movie-watching nights."

It bothered me that my sister was giving up dating for my friends. "You could get a boyfriend. Just don't tell Dimitri, Rob, and Landon about him."

Z snorted. "And not go out with my boyfriend on Friday and Saturday nights?"

"Well, maybe he goes home on Friday afternoon to work five shifts over the weekend at some fast-food place to pay for his college."

I could practically hear Z roll her eyes. "I haven't met any guys with a crazy schedule like that. And I couldn't lie to my guys about not having a boyfriend. They'd see me holding hands with him someday."

"Well, if he was your secret boyfriend..." I decided to let the subject drop. My suggestion was weak, and I couldn't think of a better one.

After a while of listening to the music, Z asked, "Can I ask you something personal? I don't know if you can answer it, but it's something that's been bothering me."

"Shoot."

"When Katharine was a cheerleader, she and some other girls would get together with an equal number of football players, and they'd have a sex party. She did that numerous times. Sometimes she'll bring that up. She'll tell me that in twenty years, we'll both be married with kids, living a boring life like our parents do now. She'll have those crazy memories to look back on and smile. All I'll have is my relationships with the loser and Brett. That's one of her justifications for pushing me to do more than I'm comfortable with. 'Make some memories for twenty years from now.' Do you think I'll regret when I'm older not having done crazy stuff in high school?"

I thought over her question for a while. "I can't tell you what you or I will think in twenty years. But I think I know the answer. Pre-med is really stressful, right? Well, all of us pre-med students need to have a way of blowing off steam to keep us sane. Friday and Saturday nights are usually our only chances to let go and do something fun."

"Like movie-watching nights."

I nodded. "Probably the most common way of blowing off steam is binge drinking."

"But Mom and Dad told you many, many times to not do that. They told you about lots of people who developed permanent drinking problems from that. You don't binge drink, do you?"

"I did once. So many of my friends told me binge-drinking stories that I had to try it. I did not enjoy throwing up. They had made it sound almost fun. It was miserable." I shook my head at the recollection. "But back to my point - probably the second most common way of blowing off steam is hooking up. Do all the sex you can do for a night or two, and then go back to being friends. I hooked up last fall. Landon did, too."

"You did? I guess I shouldn't be surprised. People have mentioned to me about pre-meds hooking up when I've talked about hanging out with you and my guys. What did Rob and Dimitri do?"

"Dimitri did binge drinking. He'd show us Americans how Ukrainians can drink so much more than us. Rob really enjoys bartending. He'd bartend parties and hook up with girls at the end of the party."

"Did all of you do that the whole year, or just last fall?"

"Let me give you the full timeline. That was how the fall semester started. Then at the beginning of November, Landon started hooking up with only one girl. They kind of became a couple. That inspired me to find a girlfriend, Tracie. Dimitri continued binge drinking, and Rob continued his bartending. Two weeks before spring break, Landon asked his girl to come home with him. She told him she didn't want to; that it wasn't a serious relationship, and that she wanted to be able to walk away from it at any time with no hard feelings. Landon thought they were more serious than that. They broke up a week later, and he started binge drinking with Dimitri."

"Poor Landon."

"Yeah. Then in April, Dimitri woke up on a Wednesday morning with a massive hangover and no memory of what had happened the previous night. It scared the hell out of him. He realized his binge drinking was getting to be a problem, and that he had to give it up. He came to me. As he had never seen me drunk, he begged me to do something with him on Friday and Saturday nights to keep him from drinking. As I could see the writing on the wall with Tracie, I broke up with her and started going to the movies with Dimitri. By the end of the school year, we had run out of movies we wanted to see. And then we went home for the summer."

"How did you meet Tracie?"

"She lived down the hall from me. We'd talk whenever we ran into each other. She was nice and good-looking. An art history major. I started eating meals with her. And then we were a couple."

"Why did you break up?"

"Because after a while, she stopped enjoying being my girlfriend. Things started great. She was very supportive. She'd do my laundry and buy things for me at the store. I think she might have been looking for the M-R-S degree. My top three priorities at school are my classes, my classes, and my classes. When she never broke into the top three, she started souring on the relationship." I swallowed. I still didn't like how I had treated her. "Being a pre-med student is something like being an Olympic athlete. You've got only one chance at success. You can never break training. You can never let yourself get the least bit behind. You have to nail every test and assignment. There's no margin for doing just okay. And that doesn't leave time to be the type of boyfriend I want to be." One of the many things I didn't like about being a pre-med. "But I brought this up to tell you about hooking up. As I'm one of the better-looking pre-med guys, I got a lot of attention from my female classmates. I had no problem hooking up every weekend. I wound up having sex with twelve different girls during the fall semester, all of them very smart and good-looking."

"Sounds impressive."

"I think so. But when I think about being with a girl, I think about Madison." Madison was my girlfriend my junior year of high school. "I loved her, and she loved me. We'd cuddle and talk on her bed, and it was like magic gold letters would appear over our heads spelling out 'forever'. It's nice that I've punched the 'Had sex with twelve different smart, good-looking girls in one semester' square on my lifetime achievement card. It came up a few times last summer when I was talking with friends back home. But already, I reminisce more about Madison than all of those girls combined." Man, I still missed Madison. "If you're the type of person I think you are, then if Katharine had invited you to some of her sex parties, twenty years from now you'd think much more about Brett than those parties."

Z was quiet for a while. "Thanks. That answers my question. And I like that answer." She reached over and squeezed my hand. "Have you talked with Madison recently?"

"I emailed her at the start of last school year, asking how she was liking school. She goes to UCF." At the end of my junior year, her dad had gotten a promotion that required moving to Miami. She had moved as soon as the school year ended. "We don't have anything in common anymore."

"Brett...wanted to keep dating. He wanted me to come home every weekend."

"It wouldn't have worked." Madison and I had tried to keep our relationship going. After four months of growing frustration and drifting apart, she told me she had been asked out and was moving on.

"I told him about you and Madison. He said we would be different." Z crossed her arms. "It was really hard to break up with Brett. He loved me just as I was, with all my nerdy ways. He didn't want me to change. He wanted to keep doing the same things. I would have been happy..." Z let out a long sigh. "But I wanted to change."

I asked gingerly, "Will you see him this week?"

"No. The things I've enjoyed the most at school he probably doesn't want to hear about. He was a great guy for a certain time in my life, but I've changed."

"I'm glad you've changed. You're pretty cool to hang out with now."

"Thanks. Back to my guys. How did the movie-watching group come to be?"

"Landon, Rob, Dimitri, and I have always been friends. Over the summer, Dimitri came up with the idea of movie-watching nights in our room. I don't know what happened to Landon over the summer, but he had sworn off binge drinking when he came back. So, he was in. They asked Vivek to join as he tells lots of jokes. At the start of the year, Rob was still bartending at parties, but he was getting bored with it. When we kept telling him about how much fun we were having watching movies, he said he'd join us if he could do bartending for us. We agreed. And then Dimitri asked you to join."

"When Rob misses, is he bartending at a party?"

"Yes. When Landon or Vivek miss, they're hooking up with someone."

"But you never miss."

"If I said I was going to miss, would you go?"

"No."

"And if you're not there, my friends would be very disappointed. When you're comfortable enough with my friends to go without me being there, I'll start hooking up again."

We took a break from talking. After a while, I stopped at a convenience store so Z and I could use the bathrooms and buy some snacks. When we got back into the car, Z said, "I have a favor to ask of you. Let me give you the background before I ask it." Z took a big breath. "I told you that Katharine got kicked out of the cheerleader and football player clique. She totally deserved it. She enjoyed causing problems and starting fights by flirting with guys. But she was still a cheerleader; from what she says the most knowledgeable one. As much as the other senior cheerleaders may have hated her, they had to keep working with her."

"Sounds lovely." I was not a drama person, and this sounded like lots of drama.

"It was. You remember Giselle Parker?"

I nodded. "Classmate of yours. Very cute, with curly red hair and lots of freckles. Moved to our town just before her freshman year. Before I could strike up a conversation with her, she had a boyfriend. She dated him for two years. By the time I heard she had broken up with him, she had another boyfriend. She was still dating him when I graduated."

"She was the go-between between Katharine and the other cheerleaders. She's a caring, sweet person that Katharine always got along well with."

"Did she go to any of Katharine's cheerleaders-and-football-player parties?"

"I doubt it. She was very devoted to her boyfriend. And he was devoted to her. They dated past graduation and decided to stay together despite going to different colleges."

I decided to double back. "Did you know that Katharine had deserved to be kicked out of the cheerleaders-and-football-player clique?"

"No. I was oblivious to all the stuff. Katharine blamed Becki, and that was good enough for me. But after a while, I figured out that the only reason Katharine was teaching me all this stuff was for me to cause Becki grief by flirting with her boyfriend."

"Did you stop flirting with him then?"

"No. This will sound awful, but I was willing to do my best to hurt Becki if that was what it took to keep Katharine teaching me about guys. I was so sick and tired of getting nowhere with guys. When I told Katharine she was evil for pushing me to try to break up Becki and her boyfriend, she'd laugh and say it was true."

I rolled my eyes. As a no-drama person, that kind of stuff had no appeal to me. "And she's your best friend now."

"Yeah. When Becki's boyfriend told me that he knew what I was up to and that he didn't want to talk to me again, I assumed my tutoring from Katharine was over. But she said, 'Let's find another guy for you to flirt with'. Neither of us had had a close female friend in a while. Making the high school cheer team is very competitive, so Katharine always looked at her fellow cheerleaders as competitors. Dating for her was a competition with the other cheerleaders for star football players and guys with nice cars. I never competed with her. She liked showing off how much she knew to the smartest girl in school. She loves talking me into doing things I don't think I should do. It's almost a game now between us - she'll pitch some idea, I'll say no, and she'll eventually talk me into it."

"But she didn't talk you into whispering into Dimitri's ear that you were wearing the panties he gave you."

"She didn't really try. She can read me very well and knows when I'm willing to be convinced and when I'm not. She reads almost everyone well, which is why she's so good at flirting."

I could see why that'd be important. "Back to Giselle."

"Katharine has kept in touch with her. Two weeks ago, she broke up with her boyfriend and has been down ever since. I've been encouraging Katharine to be more empathetic, so she decided to do something over Thanksgiving to cheer Giselle up."

"That's nice of her."

"It is. It's going to be a sleepover at our house on Sunday night."

I wrinkled my brow. "Shouldn't it be at Katharine or Giselle's house?"

"Giselle's parents have heard enough stories about Katharine that Giselle doesn't think they'd agree to a sleepover with her. Giselle told her parents that I'm rocking all my classes right now and that I've helped her a few times with her homework. So, the sleepover is about getting to know me better and finding out how I do so well in my classes. Katharine's presence is never to get back to Giselle or her friends' parents."

"Okay. No threat from me on that."

"Also, Katharine has a plan that requires it to be at our house. Or maybe multiple plans. At least one of those plans requires your participation."

"Me?" I was surprised. "I've never had a conversation with Giselle."

Z raised her hands in a 'who knows?' gesture. "Katharine wants you available to be at the sleepover. She says she can't tell me what she's planning because Giselle is being wishy-washy. I think there's more to it than that." Z crossed her arms and frowned. "I hate asking you to write Katharine a blank check for Sunday night, but Giselle is a really nice person, and I'd like for Katharine to pull something off that lifted her spirits."

"Tell Katharine that I'll go along with whatever she comes up with." This was a no-brainer. An evening with Katharine AND Giselle? I'd be a fool to turn that down, even if I didn't know exactly what would happen.

Z said, "Thanks. I so appreciate you being such a good sport for my friend."

"No problem."

* * * *

Sunday morning, we had cinnamon rolls and orange juice for breakfast. It was a nice family meal. Z and I told our parents several stories from movie-watching parties. The alcohol and Z's flirting didn't get mentioned, but the jokes and camaraderie did.

I loved my parents. They treated Z and me as adults. They were proud of how well we were doing academically. They had high standards for us, but they weren't overbearing about it. Rather than tell us what to do, they'd tell us what they thought worked and what didn't, and let us make our own decisions.

After breakfast, Z and I got in my car. The doctor my mom worked for, Dr. Harrington, had hired us to take care of their dog Bart. Z said, "I got an update from Katharine. Giselle, Laurie Hughes, and Valerie Collins will be sleeping over."

"Laurie Hughes sounds familiar, but I can't picture her. I'm drawing a blank on Valerie Collins."

"Laurie was in several of my classes. She seemed nice. I can't tell you anything more about her. Valerie is a senior in high school. I don't know her."

"Okay."

"Katharine is going to give them a flirting workshop once Mom and Dad go to bed at ten."

"A flirting workshop?" I guessed I should have seen this coming. Katharine had enjoyed teaching Z to flirt so much that her teaching a flirting workshop made perfect sense.

"Yes. Giselle, Laurie, and Valerie will take turns flirting with you while Katharine and I watch. We will then advise them on how to flirt better. Katharine hopes that after watching me flirt with your friends so much, you'd know how to handle flirts. She wants you to be out of the house when the girls arrive and come home at exactly 10:30. Nothing is to be taken seriously. Everything that happens tonight is top secret and not to be discussed with people who weren't there. You are to be a perfect gentleman. Do you agree to all that?"

"Do I have a choice? If I don't agree, the workshop doesn't happen."

"No, you don't. You gave Katharine a blank check Friday, and she's cashing it tonight. Giselle really likes the idea of learning how to flirt. She feels unprepared for dealing with guys now that she's unattached. She's only dated her two boyfriends, and both times they were going steady after the first date. But though she likes the idea of learning how to flirt, she thinks she'll be uncomfortable flirting and seeing other people flirt."

"Sounds like a tough needle to thread."

"And you will have to thread it," Z said earnestly. "You will make or break tonight. Katharine says for you to be encouraging and to make it fun. She asks that you please put the fun of Giselle, Laurie, and Valerie in front of your own."

"Why does Katharine think I can thread that needle? I've talked with her some, but it's mainly been flirting with her before or after she studied with you. She's putting a lot of faith in me."

"I've told her lots about you. She likes how you've been so supportive of me, making flirting with your friends and movie nights fun for me. You like girls but aren't a horndog. You're good-looking, but not stuck up about it. You're very long-term focused, so you won't try to take advantage of a special party. As I said, you're used to flirting and know not to take it seriously. She said you're the only guy she'd feel comfortable making the star of a flirting workshop."

I smiled at all the praise. "Okay. I'll do my best."

* * * *

At nine, I went over to the Harringtons'. I took Bart on a long, slow walk, letting him stop and smell things to his heart's content. As I did, I thought about the flirting workshop; more specifically me and the girls at the flirting workshop. Wouldn't it be great if one of the girls at the flirting workshop became my girlfriend? This morning when Z and I had gotten home after taking care of Bart, we had pulled out her last yearbook to look up Laurie and Valerie. They both looked pretty, though not as pretty as Giselle and Katharine. Valerie played forward on the basketball team and was tall. I guessed that Laurie and Valerie were also unattached. A flirting workshop would be a great way to get to know several attractive girls.

I badly wanted a girlfriend. I badly wanted to be in love with someone. Regular sex would be nice, but it wasn't my top priority. I had loved being in love with Madison and having her be in love with me. It made me feel on top of the world. I hadn't felt that way since she moved away.

"What do you think, Bart? Could one of the girls at the workshop become my girlfriend?"

Bart didn't seem to think much of the idea. Sadly, I had to admit he was right. None of them went to the same school as me, I didn't want a long-distance relationship, and there wasn't enough time during this break to even start a relationship.

If I was going to have a girlfriend, it'd be one of my fellow pre-med majors. But it was very risky to get emotionally involved with a pre-med major. So many pre-med majors wouldn't make it, and it was painful to watch those who weren't quite good enough slowly admit defeat. My roommate my freshman year had been a pre-med major, full of confidence that he'd become a doctor one day. We had hit it off and had spent most of our free time together. But as we had progressed further into chemistry, he had struggled more and more. "Struggle" isn't the right word - he had been good at chemistry, but you had to be great at it to make it as a pre-med. I had given him some help, but I hadn't been able to spend a lot of time helping him as I had to keep on top of all of my classes. He eventually admitted defeat and changed majors. I didn't see him anymore. If Dimitri hadn't stopped his binge drinking, I wouldn't see him anymore. Any of my fellow students at any time could run head on into the one required subject that they aren't great at and be forced to give up their dream. Or they could crack under the stress. Or burnout. It was best for me to not get too close to anyone, for fear that if they went down, they'd take me with them.
I sighed. As much as I wanted a girlfriend, I couldn't see it happening anytime soon.

* * * *

I got back home at 10:15. The shirt I was wearing was appropriate for playing with Bart and taking him for a long walk, but I thought I should change into something nicer for the flirting workshop. I slipped in the back door and checked out the living room. No one was there. When you came out of the kitchen into the living room, to the right was what was supposed to be a formal dining room and was now Mom's teleworking office. That was where the girls were going to sleep. It was clear. I couldn't hear anyone, but Z had told me that they would be in the kitchen when I got home. Mom and Dad had gone to bed at ten as they always do when the next day was a workday. I walked around the edge of the living room and walked through what we called the 'back hallway' but was actually a narrow space between the stairs and the living room wall. I came to the stairs up to the second floor where Z and I had our bedrooms. I looked up and saw a wondrous sight.

Two girls were two-thirds up the flight of stairs, facing upwards. Both were wearing short shirts and thong panties that left most of their marvelous asses exposed.

Katharine said something upwards in a quiet voice that I couldn't make out. I guessed that Katharine was trying to keep my parents from hearing what she said.

I heard a voice that I didn't recognize answered back quietly, "Look, tonight's top secret." It was a struggle to make out the words. "Not a word of this is to get back to my mom and dad, right?"

I didn't catch Katharine's reply.

"Then I want to go braless," continued the quiet voice from above. "I've never gone braless around a guy before."

Katharine was wearing a pink nightshirt and white thong panties. Her long, straight brown hair reached almost to her waist. The other girl had to be Laurie as Giselle was short and a redhead, and this girl had short blond hair and was about Katharine's height. She was wearing a teal nightshirt and her thong panties were black with a white stripe on top. Her hand was on her hip, and I could see her bright pink nail polish. Z and my female classmates didn't wear nail polish, so I liked the novelty of seeing it.

Katharine said quite a bit to the girl upstairs. Laurie continued to stand quietly on the right side of the stairs, looking up with her hand on the banister. She and Katharine had very nice legs; smooth and firm. Her legs were a little thinner than Katharine's.

Katharine and the girl upstairs continued talking. I stopped paying attention to their conservation, somewhat because I could barely hear only half of it, but mostly because I was focused on the two gorgeous butts in front of me. I found this view of Katharine and Laurie incredibly hot. I really wanted to push both over, pull down their thongs, and fuck them right there. I had a major woodie.

I eventually decided I was pressing my luck and moved away from the stairs. I retraced my steps and slipped out the back door. I waited until 10:30 and re-entered. This time, I headed straight toward the kitchen. Z was standing guard in front of the doorway to the kitchen, and -- in a major surprise to me -- she was wearing a teal nightshirt. She hadn't...no, Laurie had to also be wearing a teal nightshirt.

Z said to me, "Go to the playroom," and then said to the kitchen, "Eli is here." I noticed her fingernails were bright pink. I moved to the playroom.

Katharine came out of the kitchen, followed by the other three girls. She led everyone to the playroom.

"Hi, Eli," Katharine said in her trademark half-sultry tone she used for greetings. In a normal tone, she said, "Let me introduce everyone." As Katharine introduced me to everyone, I couldn't help noticing that the five girls were all wearing the same style of nightshirt -- a V-neck top, a tapered middle, and a slightly flared bottom that ended a few inches below their crotch. All of the girls looked hot in the nightshirts. The color was different for each girl, so only Z had a teal nightshirt. All of the girls had their nails painted bright pink.

Katharine noticed me looking at the nightshirts. "I had a bunch of Victoria's Secret gift cards, so I decided to spend some of them. We went to Victoria's Secret this afternoon."

Several girls giggled. Valerie said unhappily, "I didn't get to go." By this time, I had placed Valerie as the girl upstairs that Katharine had been talking to.

"But you gave me your measurements," said Katharine, "so I got you your nightshirt." Katharine then chuckled at nothing obvious. Was she chuckling about buying all the girls thong panties as well?

Katharine saved me from thinking more about that by reciting the rules for tonight, and then she said to Z, "Tell us about Eli."

Z smiled at me as she moved next to me. My returning smile was a little forced as I was feeling guilty for the impure thoughts I had had about my sister ten minutes ago. But I hadn't known it was her!

"Eli is a sophomore pre-med student at our state's premier public university. With his grades so far, he's on the path to making it to med school. He spends most of his time studying. On Friday and Saturday nights, he and a few of his friends watch old action movies, making fun of the plot holes and the bad acting. When he was young, he wanted to be an astronaut. He started an astronomy club in high school and was president all four years. He is a dog person, and last year when we had to put our dog to sleep, he came home from school to be there and cried while he held Mr. Buttons in his arms that last time. When he has free time, he reads non-fiction or science fiction."

Z looked at Katharine, who said, "That should be enough. But you left out one thing -- Eli's unattached. He hasn't dated anyone this school year." Katharine looked at me. "Is there anything you don't want to be asked about?"

I thought for a moment. "Not really."

Z said, "Don't ask him about pre-med or how he likes his classes. He doesn't want to talk about school while he's on vacation."

Katharine nodded. She turned toward Z, and it was like some secret message went between them. Z stepped forward as Katharine said to the other girls, "Z will demonstrate what you should try to do in the first round." Katharine then said to me, "Stand in front of the pool table." I moved in front of the narrow end. Z moved to the other side of the pool table and turned to face me. I backed up to the other edge of the pool table. Katharine formed the girls into a line. The pool table provided a backdrop to our little stage, with the other girls facing us as our audience. Katharine was off to the right of the line, about halfway between the line and Z, allowing her to keep an eye on everyone. She said to Z, "Start."

"Hey, Eli," Z said in a warm, friendly tone. She looked me directly in the eye and smiled broadly. "Katharine and I were talking about going somewhere for Spring Break. Somewhere far from here. What's the farthest you've gone for a vacation?"

"Stop!", said Katharine. She said to the line of girls, "Z didn't just blurt out her conversation-starting question. She set it up so that asking it would seem natural. She also didn't ask about Eli's favorite vacation. Asking about what is your favorite something is not a good conversation starter as typically most people don't have a clear favorite. The farthest Eli has gone has a clear answer that Eli should know off the top of his head." Katharine looked back at me. "Continue as if I didn't interrupt you."

Now that Katharine had pointed out how good of a job Z had done with her conversation, I was impressed. I suspected I seriously underestimated the amount of skill it took to be a good flirter.

I faced Z again and got back into a conversational pose. "Orlando. We went to Disney World when I was six and when I was eleven."

"Do you remember much from the first trip?"

"Some." I laughed. "I mainly remember how annoying my little sister was. She always wanted to go to character meet-and-greets, and I wanted to go on the rides."

"What were the rides you went on?" Z wisely sidestepped my criticism of her.

I talked about the rides I had enjoyed the most when I was six. I didn't think about that Disney World trip very often, instead thinking of the trip when I was older. Z had a certain innocence as she talked to me like she had never been to Disney World before and my adventures there were something novel and exciting for her. She kept me pulling out memories.

Katharine suddenly said, "That's enough." She turned to the girls in line. "Does that give you an idea of what I'm asking you to do?" The girls all nodded their heads. "Let's go into the kitchen and brainstorm plans for you." Katharine turned to me. "Go play some pool. We'll be back in a little while."

* * * *

Once the girls were gone, I sat down in one of the straight-back chairs along the wall and read. The playroom felt unusually empty; it was not a room I had ever read in. It was a room for having fun in. Z and I had kept our toys in the playroom when we were kids. Z had had an elaborate mini-kitchen when she was a little girl. As we got older and stopped playing with toys, Dad bought a pool table. He and I had played a lot of pool this weekend. Sometimes Mom and/or Z would join in. Despite Katharine's suggestion, I didn't play pool now -- I didn't want the sound drawing Mom or Dad out of their bedroom.

Lots of laughter was coming from the kitchen. After ten or fifteen minutes, the girls came out with Katharine in the lead. She said to me, "Each girl will talk to you for five minutes. Let them drive the conversation. Let them ask the questions and discuss what they want to discuss. This is about them practicing flirting with you. And remember the rules."

Laurie stepped forward and moved to the far side of the pool table. She was short -- maybe 5'4" -- and had blond hair, a shade or two darker than Z's. Her nightshirt was a light purple, which didn't do much for her. She said, "Hey, Eli. There was something I always wondered about you. You took classes from your dad, right?"

"A class every year."

"You got great grades in those classes, right?"

"Yes."

As I was much taller than Laurie, I had to look down to talk to her. The V-neck of her nightshirt showed a lot of chest skin. She wasn't well-endowed, but it was like her tits were calling to me: Look at us! Check us out!

"I never heard anyone accuse your dad of favoring you. If anything, he was harder on you than anyone else. You earned those grades by working hard." No one had ever mentioned this to me. I had to admit it made me feel good. "What was it like to be taught by your dad?"

I talked about what it was like to be taught by my dad. Laurie talked about taking an intro science class from him and how she liked him as a teacher. We talked about his teaching style. The whole time, I kept thinking: Don't stare at her boobs. Don't stare at her boobs. Then, mercifully, time was up. A pleasant conversation. If it had happened at a party, I would have enjoyed it, but not enough that I'd seek to have another one-on-one conversation with her later.

Laurie joined the line and Giselle took the spot opposite of me. Her red hair tumbled down in curls onto her shoulders. She was very curvy, which the nightshirt brought out. Still, her face was her best feature, and her black nightshirt put the focus on that. She had a dimple in each cheek, lots of freckles, and looked 15 instead of 18. She had such an air of wholesome cuteness about her. She was quite short, a couple of inches shorter than Laurie, so I got a good look down into the V-cut of her nightshirt and enjoyed the view. Don't stare at her boobs. Don't stare at her boobs.

"Hi, Eli."

"Hi, Giselle."

"You know, I don't think I've ever talked with you before." Giselle seemed uncomfortable. Was she shy?

"I don't remember having talked with you, either."

I waited for Giselle to say the next thing. I wanted to fill the silence in the conversation, but I remembered that Katharine wanted me to let the girl drive the conversation.

Giselle asked timidly, "What was the breed of your dog?"

"He was a mutt. My parents got him at the pound. He was about the size of a German shepherd."

"We have two dogs. Dachshunds. They're lots of fun."

I was tempted to ask about her dogs, but I knew that wasn't my role. Giselle finally asked, "What was your favorite thing to do with your dog?"

"To take him with me when I went to look at the stars. My dad and I would go someplace well away from buildings, so there wouldn't be any light. He loved exploring new places."

Giselle smiled. "Did he bark and jump around?"

I laughed at the memory. "Oh, yes. And he would race around whatever field we were set up in, smelling this tree and that rock."

Giselle's eyes lit up. She was amazingly cute. She straightened her back, and her big tits seemed to swell. Don't stare at her boobs. Don't stare at her boobs. "Did you take him on hikes or long walks?"

She got me telling Mr. Buttons story after Mr. Buttons story. Then I started feeling my eyes getting wet. Soon, tears were streaming down my cheeks. I had to stop. "I'm sorry. I still miss Mr. Buttons."

Giselle took a few steps forward and hugged me. "It's okay. It's perfectly understandable that you'd still miss a dog that you loved."

Tears kept pouring down my face. I was embarrassed about crying in front of so many people. "It was his time. He was in such pain at the end. He was a great dog, but it's time for me to let him go."

Giselle continued hugging me, pressing her head into my chest. "But you should never let go of his memories. He's still alive in your heart, and he's still bringing you joy."

I patted Giselle lightly to express my thanks for her support. She held onto me, giving me time to stop crying. After a while, she looked up at me to see how I was doing. She smiled at me and asked, "Feeling better?"

"Yeah. I'm sorry I interrupted your flirting practice."

"Don't think anything of it." She hugged me harder, putting her head against my chest. I wrapped my arms around her back. "A guy being honestly emotional really appeals to me. If you went to the same college as me, I'd definitely be looking to get to know you better." Giselle leaned back to look up at me. "That, and you're good-looking, and several of my friends tell me you're a very nice guy." She smiled at me, which tore a hole through my heart. "I think I've done enough flirting for now."

Giselle moved back into line. Katharine wiggled her finger at me and said gently, almost mockingly, "Remember the rules. You aren't supposed to hug anyone."

I smiled at the ridiculousness of her comment. "Okay. I'll do better from now on."

Giselle called out, "I liked the hug!" The girls behind Katharine laughed.

I wiped my eyes with my shirt sleeve. I took a deep breath and said to Katharine, "I'm ready for Valerie."

Katharine said to Valerie, "You go."

Valerie moved opposite of me, doing a jump stop into place. She was tall, only two or three inches shorter than my six feet. The gray of her nightshirt suited her -- she was a big, tough girl. She had short dark brown hair. With me looking straight into her face, I hoped I wouldn't be tempted to look at her boobs. But she was definitely braless; her good-sized tits wobbled against the material of her nightshirt. And her nipples were sticking out like gumdrop candies. Was she cold? She might be that cold if we were in a meat locker. I was more distracted by her tits than Giselle's.

"Hey, Eli," she said confidently. "I hear you wanted to be an astronaut when you were little. Are you still thinking of doing it once you become a doctor?"

"I've looked into it. I'd love to be an astronaut, but I'll have a boatload of debt once I get out of residency."

"What kind of physical shape would you have to be in to become an astronaut?"

We talked about what it would take for me to qualify for astronaut training. She stood closer to me than the other two girls had; kind of on the edge of socially acceptable closeness. More enjoyable than talking with Laurie, but not as enjoyable as talking with Giselle.

Katharine ended my conversation with Valerie and moved to the other end of the pool table. "Hi, Eli."

I couldn't help smiling at Katharine. I liked her. "Hi, Katharine."

"I wanted to thank you for making the time to do this workshop. I'm sure you're crazy busy with your studies and probably brought a ton of homework home with you."

"Not a ton, but I do have homework this week."

Katharine moved closer to me. "It's kind of inspiring to me that somebody I've known for years, the son of one of my school teachers, is going to be a doctor someday. I'm sure you'll be a great doctor. I love how humble and grounded you are, even though you'll be making a lot of money in the not-too-distant future."

I hadn't been expecting this kind of praise. I looked down and shuffled my feet. "Thanks."

Katharine grabbed my upper arm and turned me toward the other girls. "That's how I typically flirt with a guy. I pump up his ego." Katharine let go of my arm and stepped forward. "The thing with that type of flirting is that I learned nothing about Eli. We all wear masks, and I played to Eli's mask as a pre-med student from my hometown. I stayed behind my mask the whole time. That leads to very shallow relationships. Which is fine for me, as I love shallow, disposable relationships." Katharine gestured toward Giselle. "But I don't think that's what you want." Giselle nodded. "So, what I'm trying to teach tonight is to use flirting techniques to get the guy to lower his defenses, and then to use conversational skills to get behind his mask." The girls nodded. "I've learned more about Eli during this round than I've learned in years of flirting with him." Katharine moved to her normal spot while beckoning Z to come forward. "Z will demonstrate what you're to try for in the next round."

Z moved into position. "You've told me that you went on a ski trip with some friends last Christmas break. Where did you go?"

I started talking about my ski trip with Tracie and some of her friends. As I considered a lot that happened on the trip to be personal, I was far less open this time. But Z was able to keep the conversation going. Z was more animated this turn as she listened and talked, giving a stronger impression that she enjoyed talking to me. When I talked about skiing with one of Tracie's friends for a few runs, Z said, "I like a guy who can make friends so quickly." When I talked about snow tubing, Z said, "I'd love to go tubing like that sometime." The way she said that sounded like it was a big hint for me to ask her tubing sometime. When I talked about us playing games in our rooms as we couldn't go to a bar, Z said, "I'd be fine on passing up the bar too but would have preferred a long walk through the snow." Again, it sounded like a hint to ask her to go for a long walk through the snow sometime.

It was weird talking to Z like this, as a potential date instead of as a sister. I started looking at Z that way. With her blue eyes and blond hair, she was just as pretty as Katharine and Giselle. She was an odd mix of shy innocence and Katharine's flirty brazenness. She was letting me know she wanted to go for a long walk at night sometimes with me, but, unlike Katherine, she didn't have any experience going for a long walk at night with a guy.

Katharine ended our conversation with a simple, "Thanks, Eli. You were quite the gentleman. We're going to the kitchen and talk things over. Stay here. When we come out again, you'll have the exact same conversations. Please try to act like you did the first time." Katharine turned toward the girls and shooed them toward the kitchen. She asked me over her shoulder, "Do you know what a gentleman is?" When I didn't answer, she added, "Someone who tries to not be obvious when he stares at a girl's boobs." All of the girls laughed. Katharine winked at me. I could feel my face get hot. I was sure I was bright red.
* * * *

I thought about what Katharine had said while the girls talked in the kitchen. I felt like a big reason why I had burned out on hookups was that I could never drop my mask during them. After the weekend was over, we'd go back to being fellow students. I would have never cried over Mr. Buttons during a hookup for fear that the story would have been shared with every pre-med student. I couldn't even say which pre-med guys I didn't like because the girl I was hooking up with could be hooking up with them the next weekend.

I thought about my talk with Giselle and how she had torn a hole in my heart. I realized it was because I missed having a girlfriend that I was very close to, who'd tell me that everything's okay when I'm down. There were so many times when I was down, but I always hid that from everyone. So many times when I questioned if I wanted to keep doing pre-med, or if all the sacrifice would be worth it in the end. Z was the only person around whom I let my mask down, and then I let it down only so far.

* * * *

The second round was much like the first. Same order, same conversations. There were a lot of minor changes though. The girls complimented me more. When Laurie talked to me, she said, "I like guys with integrity" and "Guys who everyone respects really appeal to me." Giselle said something similar, "I much prefer to date someone who's a dog lover." When she said, "I'd love to go along when a guy takes his dog on a long walk," I was tempted to say, "I'll be taking Bart for a long walk tomorrow night." What Katharine taught them wasn't a straight out "I like you", but I as a guy couldn't help connecting the dots while giving the girl plausible deniability. If I rejected Laurie's advances to me (the likely outcome), there'd be no loss of face, as she never came right out and said she liked me.

Valerie started doing something similar. Again, she stood closer to me than the other girls and did little things to emphasize that she was braless. At one point, she said, "I'd like to go for long walks with a guy who's keeping in shape. Like you." She then twisted while lifting her nightshirt to show me a butt cheek. "I want to keep this firm."

I laughed, turned to Katharine, and said, "She's being so over the top that if we had been alone, I would have thought seriously about testing how firm her glute is."

Katharine made an unhappy face and then stepped forward. "Valerie, what I'm trying to teach here is how to use your conversation skills and your body language to grab a guy's attention. Once you have his attention, he's going to check out your physical assets." Katharine moved next to me and turned so she could talk to both Valerie and the other girls. "But this brings up an important point. A guy should never touch your breasts, butt, or crotch without your permission. There is nothing that you can wear, say, or do that makes it okay for him to do so. But guys will still do it. And when they do it, it's really important to take control of the situation immediately. Valerie, go back in line." Valerie moved back in line and Katharine moved to where she had been standing. "Eli, when I say what Valerie said, I want you to test how firm my glute is."

Holy shit! Katharine was asking me to squeeze her ass? Good god! How many guys in my high school had dreamed of doing that?

"I'd like to go for long walks with a guy like you who's keeping in shape." She did the same twisting and lifting of her nightshirt. "I want to keep this nice and firm."

I reached forward and gave her butt -- that I had lusted for mightily a little earlier -- a good squeeze.

Katharine grabbed my hand and pushed it away firmly while saying in an even tone, "Eli, I'm not ready to let you do that. Maybe someday when I know you better, but today is not that day. I'll let you know when I want you to do that." She didn't step back, but instead firmly stood her ground. "How did that make you feel?"

I thought for a moment about the impact of her words on me. "That I had done wrong; that I had overstepped. You still liked me, and if I did the smart thing and apologized, there was a chance you'd give me permission someday to do that."

"Great. That's what I'm hoping for." She turned to the girls. "And that's the response you should get. If the guy gets angry or starts blaming you for his actions, get out of there. If you think you can safely run out of the room, run. If you don't, do something like this." Katharine turned back to me. "Oh, Eli." Katharine moved closer to me. "Don't get angry." She suddenly jerked up her knee, stopping just short of my crotch. She turned back to the girls. "Do that and then get the hell out of there, and don't feel guilty about it. You're keeping him from doing anything worse." Katharine turned back to me. "Let's do that again."

Did Katharine just ask me to squeeze her ass again? Had I won the fucking lottery?

Katharine said her line, I grabbed a nice amount of ass, and then she pushed my hand away again while repeating her line. She turned to the girls and said, "Don't push the hand too hard or too far away. Push it just far enough away to make your point. Most of the gropes I get are not straight grabs like Eli did. The guy slides by me and gropes as he goes. Or he'll put his arm around my waist as a friendly side hug and then drop down for a squeeze. Sometimes I let gropes go, but I hate it when I do because I feel that encourages more gropes. When I do react, I try to make it not be a big deal; just me conversationally letting the guy know that he overstepped. Don't give the groper a chance to play the victim, which he will probably do if you overreact." Katharine turned to me. "Let's do the same thing, except this time grab my boob."

Jesus Christ! Was today my lucky day or what?

"Katharine, I've always found you so attractive." And I gave her tit a squeeze with my right hand.

Katharine smiled at me while grabbing my right wrist with both hands and bringing it down close to my side. "Eli, I'm glad you find me attractive, but I'm not ready for that step. Maybe some other day. I'll let you know when I am." Katharine turned to the girls and said, "If any guy does that to you, it's uncalled for, and he should permanently go on your Jerk list. But it's important to keep calm. Seize control of the situation, let him know what he did was inappropriate but don't do anything that will cause him to panic or overreact." Katharine took a step forward. "This is very important. As this is a safe space tonight, I'd suggest you let Eli touch you inappropriately during your next talk with him so you can practice how to react in such a situation. I can understand if you don't want to, but I feel like I should give you the opportunity."

Really? Katharine was trying to convince the girls to let me cop a feel?

Giselle said, "I've been groped enough times that I don't need the practice, but, Valerie and Laurie, what Katharine said is so important to learn, and I'd recommend you practice how to deal with this type of situation if you haven't before."

There was silence for a few moments, and then Laurie said, "I had something like that happen to me once, and I really mishandled it. I let the guy get away with it and afterward blamed myself. I'd like to practice taking control of such a situation."

Valerie said, "I'd be fine with practicing with Eli. I'd like to do our talk again, and we can do it then." She resumed her spot in front of the pool table.

"Eli, don't do it when Valerie is expecting it," said Katharine. "Catch her by surprise."

I nodded. I stepped out of my usual spot and said, "I'd like to make one thing clear - no kneeing me in the crotch. I don't want to be doing the rest of this workshop in falsetto."

The girls laughed as I returned to my usual position.

Valerie restarted our conversation, and I said what I had said before. About fifteen seconds before Valerie got to where she had shown me her glute, I reached out and squeezed her tit, which had been tempting me all evening by bouncing around in front of my face. Valerie froze for a few seconds, and then she grabbed my hand and pulled it away while saying something akin to what Katharine had said. And then she continued on with our conversation normally.

Valerie moved back in line, and Z moved opposite of me. I knew she'd demonstrate what the other girls were to try for the next round.

"Eli, I was thinking of watching a movie tomorrow. What movies have you seen recently, and what did you think of them?"

I started talking about the movies I had gone to see in the theater last summer. I didn't think the movies we had watched on movie night counted for what she was asking. As we talked, Z went into the full flirting mode she did with "her guys". She cocked her head cutely as she listened to me, she played with her hair, she touched me frequently as we talked, she even threw in a double entendre. I was feeling for the first time her ability to turn the minds of guys into mush. Even though I knew Z didn't mean it, even though Z was my sister and therefore off-limits, it was getting to me.

At some point, I had a horrible thought. Katharine had asked me to grope the girls to give them experience in handling being groped. She didn't mean for me to grope Z, did she? She hadn't asked Z if she wanted me to grope her or not. But Katharine hadn't asked the other girls either. They had responded, and Z hadn't. Z didn't want me to grope her, right? She was my sister, and I shouldn't grope her, right? But the more she flirted with me, the more I wanted to reach out and squeeze one of her tits.

Thankfully, Katharine put an end to Z's flirting. Katharine said to the girls, "I feel all of you made a lot of progress from the first round. Let's go in the kitchen and talk some more." As she herded the girls into the kitchen, Katharine threw me an over-the-shoulder wink and then swung her hips wildly as she finished her walk into the kitchen. Man, she knew how to press my buttons while keeping it fun.

* * * *

I looked up from my book to see Valerie enter the playroom. I stood up, pointed, and said, "The bathroom is over there."

"I came out here to talk to you. First off, this has been a lot of fun, and you've been great. I wanted to thank you for letting me know I had gone too far. My dad is the associate pastor at First Baptist. My parents have never let me have a chance to not walk the walk if you catch my drift. The only dates I've been on have been chaperoned group dates. No way could I have gone to Victoria's Secret with the rest of the girls. I had a boyfriend for six months, and we did almost nothing."

Valerie stepped right next to me and smiled at me. I was a little surprised but decided to see what happened. She gave me a short kiss on the lips, and then she leaned into me. My arms seemed to naturally wrap around her. She put her head on my shoulder. I had never hugged a girl this tall before.

Valerie said, "Okay, now we've done more than my boyfriend and I ever did." I expected Valerie to pull out of arms, but she kept her head on my shoulder. "Like I said, all my experience with boys has been in very controlled circumstances. Knowing that whatever I did tonight wouldn't get back to my parents, I decided to have a bunch of fun that I can't normally. And I went a little too wild."

Damn, she felt good in my arms. "Well, after tonight you'll have a better gauge of what you can and can't do."

"True. The biggest revelation tonight for me has been Katharine showing us how to handle being groped. I've always been told that I should always dress conservatively, or some guy will grab my butt, and I'll be traumatized. That if I flirted, some guy might grab my boobs, and I'd be scarred for life. Katharine saying that being groped is unpleasant but something that I can handle when it happens was a huge shock to me. It was also shocking to me that Giselle had been groped a lot. If there's anyone who's not led a guy on, it's Giselle. But it wasn't this horrible, life-shattering experience for her either."

For someone without a lot of experience, she certainly knew how to make an impression on a guy. Her unbounded tits were pressed firmly into my chest. For like the hundredth time tonight, I was hard. "I know this will sound crazy, but I want you to grope me every time we have a conversation. Squeeze my butt. Grab both of my boobs. Catch me by surprise. I want you to help me overcome my fear of being groped. Because if I don't overcome that fear, I'll never put to use what Katharine is teaching us." Valerie pulled out of my arms, took a step back, and looked me in the eye. "Will you do that for me?"

It would be tough to say no to almost any request. But to grope her? "Sure."

"Thanks. I'll tell everyone what I told you." Valerie turned and walked toward the kitchen. She stopped and turned back toward me. "Besides, I like you groping me." And then she walked back into the kitchen.

* * * *

The third round started like the first round. This time, Laurie asked me about Mr. Buttons. Laurie's family had a rescue greyhound, whom Laurie missed a lot while at college. We alternated telling dog stories, so I had time to recover my composure after each Mr. Buttons story. She seemed on much surer footing talking about dogs. The main difference this time was her touching me with her finger every so often to get my attention or reinforce her point. I was enjoying this conversation so much more that I hated to interrupt it by groping her. I went ahead and grabbed her tit as gently as I could. It took her a moment to react. "Eli, we're friends," she said as she took my hand. She sounded very disappointed in me. "That's not something a friend should do. You've really hurt my feelings. Please never do that again. But we're still friends." I felt terrible for what I had done. She resumed the conversation, but I was rattled.

When Katharine called time, I said, "I'm sorry, Laurie. I didn't know it'd bother you that much."

"Oh, don't worry about it," Laurie said, smiling at me. "This time didn't bother me. It was the first time that bothered me. I didn't say anything that time. It feels good to have said something this time."

Giselle moved opposite of me. Giselle asked me about the difference between fantasy and science fiction. She had read The Chronicles of Narnia and The Lord of the Rings series. Her knowledge of science fiction was basically Star Wars. I explained what I thought the difference was between fantasy and science fiction, and the type of science fiction I liked. She was much more comfortable this time initiating and controlling the conversation. It was still a huge battle for me to not stare at her tits. It was a good conversation. When she said, "I like spending an evening with my guy reading on the couch," I wanted to volunteer to come over to her house with my book the next night. Would I talk to her again after tonight?

Then it was Valerie's turn. "Hi, Eli."

I felt she had cheated by getting a bonus flirting session while everyone else was in the kitchen. I decided to make this one a challenge. "Not right now, Valerie." I put my hands to my head. "I've got so much homework to do."

A confused look came over Valerie's face. She kept on her script. "I wanted to tell you how much--"

"I don't want to talk. I'm buried right now. I've got three tests when I get back to school."

Valerie stood there with her mouth open. She turned to Katharine, who leaped into action. "I'm sorry to hear that. You're really tense, right?"

I watched Katharine grab one of the straight-back chairs. I said, "Yeah. I've got so much homework to do." I couldn't keep up my conversation. Katharine put the chair in front of me so that it faced me. What was she up to?

"Sit down for a minute. Let me see what I can do about that tension."

I sat down on the chair facing its back with the girls beyond. As soon as I sat down, Katharine began kneading my back muscles. "Oh, I can feel that tension." She pressed a couple of spots, and relief flowed through my back. I guessed that reading my book hunched over had caused my back to stiffen. Katharine's fingers were like magic; they seemed to know where every stiff spot was and just the right amount of pressure to relax it.

Katharine said to the girls, "When you go to talk to a guy, you should have a script of what to say in your head. But pay attention to how he reacts. When you're flirting, the message you're trying to deliver is that you will meet all his needs if he can win your heart." Katharine's fingers continued to work their magic. I could feel myself getting floppy. "What I've been teaching you is how to be his cheerleader. Once you've got his attention, it's easy to convince him that you're his sex goddess - Giselle asked me to not teach about that. But sometimes, what the guy wants is a mother. Some guys, if you tell him that you'll give him a massage like this every time he comes home, and then you'll serve him a home-cooked meal, he's thinking about marriage." The girls laughed. "It's important to figure out quickly what needs are most important to him. For Eli, I think that while sex and cheerleading are important, being his best friend would be the most important thing." My jaw dropped. How did she figure that out? And it was right on the money. "I'm a rotten best friend and a terrible mother, so I know to put off guys who are looking for those two things, even if they think I'm the woman of their dreams." Katharine gave my shoulders a final squeeze. "Feel better?"

"I do. Thanks."

"Now, let Valerie practice what she's learned."

I stood up and moved into position. Valerie's nipples were still poking out proudly. She said, "As I was saying, I've always admired your T-shirt collection." Half of my t-shirts had astronomy stuff on them, and the other half were from places I had been. I was wearing a black shirt with a drawing of Saturn on it and Saturn facts beneath the drawing. I talked about my shirt and other shirts I particularly liked. I had the suspicion that Valerie hadn't known me from Adam in high school, so hadn't admired my T-shirt collection, but she was faking it very well.

At one point, I said, "I like your nightshirt. The material is attractive and looks comfortable." I pointed at her chest. "What's that?"

Valerie looked down at her shirt. I brought both my hands up and went for her tits. With both thumbs, I played with her big, protruding nipples that had been driving me nuts all night. Valerie grabbed my hands and pushed them down while giving her little speech. When she was done, she gave me a big grin. Once again, I was hard. Valerie resumed her conversation, and, eventually, Katharine said, "Stop".

Z came out to demonstrate for the next round. As Z had seemed to go all out last time, I wondered what she'd do this time. This time, Z asked me about good restaurants close to campus. She kept the flirting down to the level of the second round, but this time she told me what she was looking for in dates or a relationship as she flirted with me. "When I'm out on a date, I prefer eating somewhere fun instead of fancy." "Once I have a boyfriend, I'd let him pick the restaurant we'd go to." "I like to share meals on a date, so I like that they have several items that would appeal to both me and the guy I'm with." "I'm the type of girl who likes to pay her share when we go out, which would be a good thing at a restaurant that expensive."

When Z was done, Katharine started herding the girls toward the kitchen. Valerie was the last one to move. She caught my eye and then puffed out her chest, flaunting her still-hard nipples. She gave me a grin and walked toward the kitchen. Again, Katharine gave me an over-the-shoulder wink just before she disappeared. I picked up my book, but I was in no mood to read.
* * * *

As I sat in the chair, I kept chuckling about Valerie - her innocent eagerness, her wanting to be bad now that she could do so without it getting back to her parents. Her conversations hadn't been very interesting, so I had no interest in her beyond making out. But making out was fun.

I had to admit that the flirting workshop so far was a lot more fun than I had thought it would be. I felt like I had gotten to know Giselle, Valerie, and Laurie much faster than I normally would, and I liked all three of them. I had flirted with Katharine a lot over the years, and she was taking that flirting to another level. I still couldn't believe that I had groped her ass and boob. She was coming on to me much more than she ever had before. But I had the feeling she was just yanking my chain. Maybe she was upping the level of flirting as a way of thanking me for going along so well with the flirting workshop?

But as much fun as the workshop had been, it was becoming repetitive. Hopefully not too many more rounds.

* * * *

The girls came out, and Laurie assumed the position. What she slipped into her conversation was that she wanted a guy who would do fun things with her like go to the movies and play party video games. Giselle was up and what she wanted was a guy who wants a long-term relationship where he spends a lot of time hanging out with her. I wasn't surprised. Valerie wanted a guy to have fun with while keeping their relationship secret from her parents. Valerie's "fun" to me had little in common with Laurie's "fun". The one big change in behavior was the girls did things with the hair as they talked to me; fluffing their hair, running their hands through the hair, tossing their hair, playing with the hair, chewing their hair.

When Valerie and I were talking, I went to grab her ass. She saw it coming and twisted slightly so I could get a better angle. She did her speech and then continued on. I peeked at the girls to see what they thought of us. I could see Z standing behind the rest of the girls with her arms crossed. She looked very unhappy.

When Valerie was done, Z didn't give a demonstration this time. The girls went back into the kitchen, and I closed my eyes and relaxed. I was worn down and wanted to regain my energy for the next round. I let my thoughts drift for a while, and they kept coming back to the image of Katharine and Z on the stairs. To get that off my mind, I considered the girls in the workshop. Laurie was nice but didn't excite me. Valerie made me feel guilty. Showing a sheltered virgin the joy of earthly pleasures was very appealing, but we had nothing in common besides the desire to make out madly, and I didn't want to be the guy who goes as far as he can with a girl and then leaves with no intention of seeing her again. I liked Giselle. I felt like she was the opposite of Katharine; someone who didn't have much of a mask. But I didn't see anything happening between us. I had the feeling that she was looking for strictly a long-term relationship, so she'd pass on me. She was more of a nice fantasy than a serious interest.

And then there was Katharine. My, oh my, Katharine. I had a major crush on her my senior year of high school. Her every visit to our house had been sweet torture. I had kept waiting for her to give me a sign that she was interested in me, that I wasn't just the guy she flirted with before she started studying with Z. But she never did. This evening reminded me why I had always been in lust with her. She was the same as she had always been - gorgeous with this immense presence. I was happy to spend time with her again. But I no longer had a crush on her. I thought about why. What I eventually came up with was Katharine hadn't changed, but I had. I was no longer a small-town boy enraptured with one of the prettiest girls in school. I was a pre-med major now. Pre-med was my universe. I spent almost all of my time in my pre-med classes, studying for my pre-med classes, or talking with my pre-med friends about our pre-med classes. Katharine wasn't a part of my pre-med universe, so she didn't fit into my life. Her beauty and presence didn't touch me anymore; there was now a distance between us that hadn't been there in high school. She was now akin to an actress on a movie screen; I admired her beauty and presence but knew it wasn't for me.

Also, she had said a couple of things that made it clear she wasn't the type of girl I wanted to date. Despite the years of us flirting, I didn't know much about her beyond she was an expert at pushing my buttons. Tonight, she had come across as so smart, so knowledgeable. Then I remembered Z telling me that if she were to date one of my friends, they'd be disappointed with her as they only saw what she wanted to show them and not the real her. Would Katharine keep her mask up if we were to date this week? Probably, I realized. Suddenly, dating Katharine was much less appealing. If anything were to happen between us, it'd be a shallow bit of frolicking. Still, it'd probably be damn awesome shallow frolicking.

How would this workshop change my relationship with Katharine? I saw her regularly because she was Z's best friend. I couldn't picture her acting significantly different than she always had. She'd return to being someone I enjoyed flirting with, to being my favorite sex fantasy, and to being someone I'd never seriously consider as a girlfriend.

What about Z? If she wasn't my sister, where would she fit in compared with the other girls? I had a more complete relationship with Z. Katharine had been totally right when she said that sex and cheerleading were important to me, but being my best friend was the most important thing to me. Z was already filling the female best friend role. We talked a lot about school and my friends. She was good friends with my best friends. She had all the traits I admired in a woman - attractive, smart, hardworking, and excelling in a difficult academic field. She spent enough time with pre-meds to understand the pre-med life and to talk the pre-med talk, but she wasn't feeling the pressures that pre-meds felt. She was enjoying excelling in her classes and shared that joy with me and my friends. And if she hit a little hiccup, she wouldn't crash and burn in Engineering. She'll be there for the distance. She's the one female I'd feel safe building my life around, even if it was a modest sibling relationship.

I was still shaken by how much I had wanted her when she was on the stairs. Had my subconscious known it was Z? Had I been lusting for my sister for a while, and because I could justify not recognizing her my mind went wild with sexual fantasies about her?

Would this workshop change my relationship with Z? I had been impressed by her performance. She had demonstrated a conversational agility I hadn't known she possessed. I hadn't looked to her for an interesting conversation, but I would now. This workshop would give us a special memory, an additional bond, and a pleasant secret to re-share. I could see us discussing it in the future when it was only the two of us, comparing things that just happened to what happened during the workshop. This workshop really opened my eyes to what an attractive woman Z was.

I really liked my sister. I was glad she spent a lot of time with me and my friends so far this year. I almost wished Z wasn't my sister.

* * * *

Katharine led the girls out, saying, "Last round. Each conversation will be ten minutes. Each girl will use both topics she discussed with you earlier and in general use everything they've learned tonight."

Discussing the same things over again didn't make for the most stimulating conversation, but it was interesting to see the improvement in their flirting. Surprisingly, Laurie was the best flirter of the three. Giselle was the one I wanted to date the most, primarily because of how cute and sexy she was. I didn't try to grope Valerie this time. I didn't think I could surprise her, and the recollection of the unhappy Z deterred me.

And then it was over. Katharine said, "Each girl would like to thank you, Eli."

The girls were in a line, so I stood in front of Laurie. She said, "Thanks Eli for a great evening." She gave me a brief, friendly hug. "I really enjoyed talking with you."

"I enjoyed talking with you too. It was good to get to know you."

I moved in front of Giselle. She hugged me right away. "Thanks for doing this. This did wonders for my confidence. And it was a blast."

"I had a blast talking with you." Giselle ended the hug and stepped back.

I moved in front of Valerie. She said, "My eighteenth birthday was two weeks ago, and this was the best birthday present ever." She hugged me and said quietly to me, "I'd love to see you some more this week."

"You were a lot of fun to talk with." Valerie stepped back into line.

I said to the three girls. "Thanks for being such pleasant company. This has been the most enjoyable evening I've had in a long, long time." I turned to Katharine, who had moved next to me. "And thanks for asking me to participate."

"Let me thank you for doing such a great job." Katharine kissed me, her warm lips pressing firmly against mine. My arms automatically went around her. After a few moments, she pushed her tongue against my lip and then gently into my mouth. I was too surprised and overwhelmed to do anything. Katharine pulled her tongue back, held the kiss for a second more, and stepped back, leaving me partially stunned. She smiled at me and said, "We're going to keep talking down here. Go up to bed."

I nodded, shook my head to clear it, and walked over to the stairs. I gave everyone a final wave goodbye and headed up.

Once in my room, I got naked. I grabbed some baby lotion and a tissue and started stroking my mostly hard cock. It quickly reached full attention and stroking it felt much better than normal. I thought over the things that happened tonight, and I came quickly. The thing I was thinking about as I came was Katharine and Z on the stairs.

* * * *

My alarm went off at seven the next morning. I could have slept later, but I had promised my parents I'd help make breakfast. I got dressed and headed downstairs.

When I moved off the stairs, I could see my parents cooking in the kitchen and the five girls slowly waking up in Mom's office. They were all dressed in nightshirts that were much longer, looser, and thicker than what they had worn last night. I decided to cut off Valerie from trying anymore to get me to ask her out. I walked over to where Valerie, Laurie, and Giselle were lying on the floor, got down on my haunches, and said, "Katharine asked me to participate in her workshop to make a special evening for Giselle. She didn't do it so I could hit on any of you. I feel like you all made yourselves vulnerable to me last night, and for me to try to go out with one of you would be taking advantage of that. So, I won't ask for anyone's phone number nor will I give out mine. Thanks again for a fantastic time."

I got up before they could react and joined my parents in the kitchen. They were cooking scrambled eggs and bacon. I took over the cooking, so they could eat. Once my parents finished eating, they took off. The girls came in and took over the dining room table. Valerie looked unhappy. Katharine gave me a sly grin and a wink. I served them eggs and bacon. I then cooked an omelet and ate it next to the stove. During that time, I'd occasionally make eye contact with one of the girls. They always smiled at me and returned to their conversation. The flirting workshop was already a happy secret; a pleasant memory that was never to be discussed.

At nine, I came down the stairs. Katharine was at the door, talking with Z. A quick check revealed she was the last girl to leave. Katharine gave me a quick wave, said goodbye to Z, and then was out the door.

I said to Z, "You don't have to go over to the Harringtons'. I'll take care of everything."

"No. I want to go."

"Okay. Change and we'll go."

We got in my car and drove over. I asked Z, "How much sleep did you get last night?"

"None. All of us girls talked for a while, and then Katharine and I talked after the rest went to sleep. I'll crash when we get back."

"What did everyone think of the workshop?"

"They loved it. Giselle was feeling lost at college, a small-town girl at a big school. Like me, she's having a tough time making friends. And then her long-time boyfriend dumped her. She was feeling down, and now she feels much better." I was glad to hear that. "Valerie was very disappointed when you announced you wouldn't date anyone. She had already talked with Giselle about providing cover when she spent time with you."

I wasn't too surprised by that. Had I made the right decision? I thought so.

"Last night, the other girls talked about what they are looking for in a boyfriend. What are you looking for?"

Z took a big breath. "I'm like Katharine in some ways but not in others. Katharine wants a boyfriend who'll let her do whatever she wants and who trusts her to make things okay. I'm very much like that. I feel like I'm growing a lot at college, and a large part of that is because Katharine talks me into doing things I'm uncomfortable doing. My social skills and self-confidence have improved dramatically. I want the freedom to keep doing new things, to change and grow."

"Okay."

"I can tell you're interested in Katharine. If you dated her, could you handle allowing her to do whatever she wants?"

I thought for a bit. "I like Katharine, but I don't see us dating. There isn't enough time for us to date now. When Dad gets off work Wednesday, we'll be spending the rest of our time home with family. That means I'd have at most two and a half days to be with Katharine. And then I'll be back at college with finals coming up soon."

"If you had a chance at dating someone like Katharine at college, could you handle allowing her to do whatever she wants?"

I frowned. "There's no one like Katharine. Everyone is unique, and she's more unique than most." I thought for a bit. "But I can see letting my girlfriend at college do whatever she wants to a certain degree. I spend so much of my time studying that she'll have to have a life of her own. But when it comes to the weekend, I'd expect to be her top priority, and she'd be mine."

Z nodded. "Katharine doesn't want a serious relationship. She's not looking to fall deeply in love or be heavily committed. When it stops being fun with a guy, she moves on to the next. I convinced her that when she got to college to slow down, date a few guys to figure out who she wants to commit to, and then try to make that relationship work. Now she's dating three guys at the same time while flirting with a few more."

I laughed. "She's repeatedly punching the 'dating three guys at once' square on her lifetime achievement card. Very impressive."

"I think she's much happier just dating. She likes having fun with lots of different guys. I'm the complete opposite of that. If I date a guy, I want us to fall quickly in love and to be totally committed to each other. Where are you on that scale?"

"I'm at the same end as you." Thinking of Katharine made me shake my head. "It's so surprising to me that you're best friends. I see you and Giselle as having more in common."

"When I was struggling, Katharine saw in me what I could be. No one else did. And she helped me become the person I want to be. We forged a bond over the last year that I'll never have with anyone else. I can tell Katharine anything, and she can tell me anything. No judgment, only support."

"Wow. That's great. I've never felt like that with any of my male friends." But that didn't answer my question. "But what do you have in common? What do you talk about?"

"Boys." Z laughed. "I've been raised to be a good girl. If I was best friends with Giselle, we'd have pleasant conversations about how our very proper relationships were going. But Katharine knows I have a bad girl streak in me. So, my talks with Katharine about boys are completely different from what I'd have with Giselle. Katharine is always telling me about what bad things she's doing with boys, and she's always pushing me to do crazy things."

"And you do the crazy things."

"Yeah. It's like when Katharine dares me to do it, I can't resist the dare." She thought for a moment. "Doing the crazy things makes me feel so alive. But Katharine has to dare me. If I were to do a crazy thing on my own, I'd just feel stupid." Z suddenly changed the topic. "Why not go out with Valerie? You don't have anything planned for the next few days, and she seemed totally up for a brief, hot fling."

"Because I'm looking for something long-term. I'm looking for something where I could be me. With Valerie, it'd be all about making out, and, as Katharine said, I'm looking much more for a best friend." I had another thought. "I think we'd both be disappointed if we dated. I don't see us having that much in common, and the date wouldn't live up to the magic of last night. This way, we'll always have what might have been. Same for Giselle and Laurie." I thought about Z and my friends. "I can see now why you don't want to date Dimitri, Rob, or Landon. You've had enough fun with them that there's a certain magic in those relationships, but it's so hard to have a happy romance when you're pre-med, so you'd be disappointed if you actually dated them."

Z's phone played its message-received music. Z picked it up and read the message. "It's from Katharine. Giselle is very glad you told Valerie you wouldn't date her as she was very uncomfortable about Valerie pressing her to provide cover."

"Okay. That's good. I liked Giselle, and I'd rather make her happy over Valerie. I was impressed at how she handled my crying over Mr. Buttons."

"Giselle is a super-nice person."

Z told me Giselle stories until we arrived at the Harringtons' house. They had a ten-foot fence around their big backyard and an eight-foot gate in their driveway. I pulled into their driveway, pushed the remote to make the gate open, and then drove around to the back and parked outside of their garage. We got out and walked around the corner to their covered porch, which was thirty feet wide and twenty feet deep. The right side of the porch had a door that led into the kitchen. The middle was patio furniture. On the left was a hot tub. To the left of the hot tub was a door to the master bedroom.

I had spent many an evening on this porch. Dr. Harrington's youngest son Rand was my age. We had been on lots of sports teams together when we were young. During those years, my family had regularly come over, and Dr. Harrington would grill us dinner while Rand and I had taken turns throwing a tennis ball for Bart to fetch. During my high school years, I had continued to visit regularly. Rand and I would talk about being pre-med majors and eventually doctors. Rand was now studying pre-med at a prestigious private university.

I said to Z, "Dr. Harrington is why I'm going to be a doctor."

"Did he say something that inspired you to be a doctor?"

I smirked. "Actually, he tried to talk me out of going pre-med. Mom arranged the talk. He told me that its long hours, insurance companies make your life hell, and the money isn't what people think because of all the debt racked up in getting through college and med school."

"So, what was it if it wasn't something he said?"

Z unlocked the kitchen door, and Bart came charging out. As Bart was twelve, his charge wasn't as fast as it used to be. He went straight to me, and I started petting him. "Who's the good boy? Who's the good boy?"

As I was petting Bart, Z went into the house. I'd spend the stay in the backyard with Bart as Z took care of everything in the house. I knew she'd disarm the alarm, mix some meds into Bart's dog food, set that down for him, and then go water some plants.
After a few pets, Bart jogged off to do his business. It was a brisk morning, so Bart wouldn't want to stay outside too long. He came back for some more pets, and then he went off to make sure the backyard smelled the same as yesterday. I smiled as I watched him. The autumn air smelled good to me.

Z came out and said to me, "So what did Dr. Harrington do to make you want to be a doctor?"

"It wasn't what he did. It's how everyone treats him. Everyone respects him and looks up to him. Dad's GPA as a pre-med major was just a little lower than his, and Dad doesn't get any professional respect in comparison. When I was a little kid, I could see the difference in how people treated Dr. Harrington and Dad. I want people to treat me like they treat Dr. Harrington."

Z walked over to the hot tub. "Did they drain the water before they left? Or might it freeze tonight?"

"I doubt they'd drain it for a week's vacation." I grabbed the top and started lifting it off. "The water is probably heated and kept circulating so it won't freeze." I eventually got the top off and stuck my hand in the water. "It's warm."

Z stuck her hand in too. "It is. Feels nice on a cool morning like this."

Bart came back. I gave him some more pets. "You ready to go inside, boy? Have you had enough fun outside for now?" I'd come back this evening and take him for a walk.

Bart walked to the kitchen door. I let him in, following behind. I looked up at the security camera. There was a camera inside at every door and several outside covering the door. There wasn't one on the covered porch. I turned on the alarm, went outside, and locked the door. I turned to see Z standing in front of the hot tub, looking at it.

I joined Z in front of the hot tub. "At night, Dr. And Mrs. Harrington like to wind down in the hot tub and then slip off to their bedroom."

"It looks inviting. Have you been in it before?"

"A few times with Rand." We had spent the whole time fantasizing about which babes we'd want in the hot tub with us. "Have you ever been in a hot tub?"

"No."

"They're nice for relaxing and talking. At least this one is. It's really big." It was about fifteen feet wide, eight feet across, and over four feet high. "It's a swim spa. Mrs. Harrington can use it for swimming workouts as it has jets that create a current strong enough that she swims in place. But it's also got seating and other hot tub features." I was curious as to what Z was going to do. We'd been taking care of Bart when the Harringtons were out of town since they got this three years ago, and she'd never exhibited any interest in it. Why now?

Z splashed her hand in the water a few times. "I'd like to go in," she said with a lot of longing in her voice. "It'd be nice to relax for a little bit before heading home to sleep, but I don't have a suit."

If she really wanted to go in, I wouldn't stop her. "You could get in naked. I wouldn't look."

"Is there some way we could talk comfortably without you seeing me naked? Maybe you could sit in a patio chair?"

"You could turn the jacuzzi jets on. They generate a lot of bubbles. I won't be able to see under the water." Z gave me a questioning look. "Try it. If you don't think the bubbles provide enough coverage, I'll sit in a patio chair. But I'd rather be close to the warmth of the hot tub."

"How do I turn on the jets?" I showed her the controls. "Okay. Turn your back."

I turned away from the hot tub. I heard Z shed her clothes, get into the hot tub, and start the jets. I asked, "What do you think?"

"I think this is fine."

I opened the duffel bag full of towels the Harringtons kept next to the hot tub. There was a padded bench on the sides of the hot tub next to the house so people could sit on the bench and dangle their feet in the water. Z's clothes were on that bench, and I tossed a towel on top of them. It would be chilly drying off and changing back into her clothes.

In the corners of the left side of the hot tub were two seats. Z was slouched down in one of the seats, so her boobs were underwater. I couldn't see them because of the bubbles. Z had her arms along the edge of the hot tub. She had a contented smile on her face. "This feels wonderful. Very relaxing." I was envious.

I stood next to the hot tub, close to Z but facing the far end. If she sat up suddenly, I shouldn't be able to see anything. I had never been with Z when she was naked before. I wouldn't try to see her naked, I didn't think she'd let me see her naked, but, honestly, I'd be fine with seeing her naked. I had seen her show off her body twice to Dimitri, and nothing awful had happened. After seeing her on the stairs last night, I wouldn't mind seeing more. Also, I was curious about what Z was going to do now that she was naked in the hot tub.

Z asked languidly, "Am I your best friend?"

"What?"

"Am I your best friend?"

Her question was so out of the blue that I wasn't sure she had really asked it the first time. I thought it over and said, "You're my best female friend."

Z swept her hands through the water a couple of times. "I'd say you and Katharine are both my best friends, but in very different ways. You're the more relaxing one to be with. With Katharine, she's always pushing me. We're pushing each other, actually. With you, it's about having a good time. I learn a lot from you, but you never push me to learn. I feel safe doing daring things around you."

"Like getting naked in a hot tub?"

"Like getting naked in a hot tub. Now, I'm glad I did it. Am I your best friend of either gender?"

This question made me uncomfortable. I didn't want to think about whether my sister was my best friend or not. Sisters weren't supposed to be best friends. Still... "I'd say you're my best friend."

"Are you getting cold standing there?"

I shrugged. "It's not all that cold."

"It's a lot warmer in here. Why don't you join me?"

Z relaxing in the warm water had looked appealing. "Sure. Don't look."

Z put her hand over her eyes. I got another towel out of the duffel bag, stripped down, and got in. The hot tub had underwater ledges for sitting on the long sides, and I sat down on one on the far end from Z. I couldn't see Z's boobs as she was in the water up to her neck.

Z said, "Come closer."

I moved to the end of the ledge closest to Z and angled away from her. She asked, "You okay?"

"I'm fine. As you said, the water feels good."

We sat contentedly for a while. There was no rush - Mom and Dad wouldn't be home for hours, and I had nothing planned for the day. Maybe some Christmas shopping.

Z asked, "Do you ever get jealous when I flirt with your friends in front of you? Katharine once said that you complained about my flirting with them because you were jealous."

"No. It bothers me that you come over to see me and then barely talk to me."

"I was always talking to you when I flirted with your friends. I told them all the news I had. I didn't see any point in telling you too what I had told them."

I could see her point, but it still annoyed me that I had never been the person she had talked to. "Were you jealous last night?"

"In a way. I got angry when Valerie showed you her butt. I didn't like how aggressive she was with you. She was invited to learn how to flirt, and she was only invited because Giselle wanted company while learning how to flirt."

"So, you weren't jealous of Giselle, Laurie, or Katharine?"

"No."

"I did a lot more with Katharine than I did with Valerie."

Z laughed. I was tempted to look at her, but I was afraid I'd accidentally see her boobs, so I continued looking at the other end of the hot tub. "I knew Katharine wasn't serious. She'd talk with me before she did anything serious with you."

"And she didn't?"

"You're out of luck with Katharine."

I wasn't surprised. A little disappointed, but not much. "I groped Valerie and Laurie so they could practice handling those situations. Had you wanted me to grope you?" Had my sister wanted me to squeeze her tits or ass?

"Yes and no. I'd like to practice handling those types of situations, and if it had been just Katharine there, I would have asked you to. But not in front of the other girls."

"I don't know if I'd be comfortable doing it in front of Katharine. You trust her not to tell anyone I groped you?"

"Absolutely. She's a great best friend. One reason I've been slow to make friends at school is that I spend so much time communicating with her. The one time in our friendship we didn't have much to talk about was when I was dating Brett. I didn't want her talking me into doing anything crazy with him, and she seemed uncomfortable hearing about how happy Brett made me. Our conversations were very superficial during that time. But if I had a secret boyfriend like you suggested on the drive home, I think that wouldn't affect my friendship with Katharine. She could still talk me into doing crazy things with guys other than my secret boyfriend."

"Secret boyfriend? I wasn't serious when I suggested that."

I heard Z move off her seat. A few moments later, she was floating in front of me with the water at her neck. The bubbles did cover up her body below the surface, but I could faintly make out some skin. I knew her breasts were floating bare a few feet away from me. Z reached forward, grabbed my hand, and pulled me forward. I moved off the ledge and was now in the center of the hot tub with Z. The water was about four feet deep here. I bent my knees, so my head was just above the water. Z and I were now about two feet apart. I couldn't see anything, but I knew that we were so close and naked.

"Let's practice you groping my boob."

"We're naked!"

"So what? No one will know. And if we don't practice it now, we may well forget to practice it later."

I was torn. I knew I shouldn't do it. But Z had made a good point for doing it now. And even though it was wrong for me to feel up my sister, I did want her to have the practice of handling that situation. Was feeling her up while she was naked all that worse than feeling her up dressed?

"Okay. Let's do it."

Even though I couldn't see Z's boobs, I had a good idea of where they were. I extended my right hand and lightly cupped one.

Z raised her hands slightly out of the water. "Oh my," Z said in a bored tone as she moved her hands slowly back and forth, "Someone is squeezing my boob. What shall I do?"

I let go of Z's boob and rolled my eyes.

Z said over-enthusiastically, "How did I do?"

I shook my head. "That was not anywhere close to what Katharine taught you to say."

"You have to do it when I'm not expecting it. Back to you and Katharine. For someone uninterested in dating her, you spent a long time checking her out on the stairs last night."

Did Z know? She hadn't reacted to my presence. "I'm not sure what you mean."

"I heard someone coming down the back hallway and knew it had to be you. The girls would have walked across the front of the living room. And they would have said something instead of standing there silently. Why did you spend so long checking her out if you aren't interested in her? Or were you checking me out instead?"

I was busted. "I didn't know it was you. You were wearing a nightshirt I had never seen you in before, and you had nail polish on which I hadn't seen you use before."

"Who did you check out more, me or Katharine?"

"You. You were closer. I thought you were Laurie." I decided to change the subject. "I've never been in a hot tub naked with a girl before."

Z giggled. "Me neither. Or with a guy." We both laughed, but it felt kind of forced. Was there some sexual tension between us? "Another square punched on our lifetime achievement cards."

I nodded. "Twenty years from now, you'll be able to tell your friends at Bunco Night about it."

"I couldn't tell them it was my brother I was naked with."

"You could tell them it was your secret boyfriend."

Z smiled. "I could. How did you not know it was me on the stairs? Yeah, I was wearing something you hadn't seen before, but my hair was the same. How many times have you seen me from the bottom go up the stairs?"

I didn't want to answer that. I had to have known and had just suppressed the knowledge to make it okay for me to want Z so much. Instead, I asked, "Why did you stand there unmoving if you knew I was at the bottom of the stairs checking out you and Katharine?"

"If you wanted to ogle Katharine, I didn't want to stop you. And...this is going to sound terrible, but I'm very insecure. I wanted you to check me out and like what you saw. The whole time you were down there, I imagined you were looking at me and smiling at what you saw. That made me feel really good."

"I liked what I saw very much. You're beautiful, Z."

Z looked down bashfully. "Thanks."

I brought my hand forward and cupped her breast again. Z's head snapped up, and she stared at me, but she didn't say anything. Her boob had felt good in my hand - a nice size and shape, a decent heft with smooth skin. I could feel her hard nipple against the palm of my hand. Z continued to stare at me intently. I could feel my heart pounding in my chest. We stared at each other for who knows how long; it seemed forever but when Z grabbed my wrist and pulled my hand away, it seemed not nearly long enough.

"I'm not ready for you to do that, Eli," said Z in a husky tone. She looked serious but not angry. "We aren't there in our relationship. Yet. Wait for me to tell you to touch me."

Then Z smiled, lighting up her face. She moved toward me. "Thanks for doing that with me." Z gave me a short thank-you kiss on the lips. She pulled back and gave me an impish grin. "Now, let's practice you grabbing my butt."

I couldn't answer Z. I was trying to tell myself that Z's kiss wasn't a big deal, just a little thank-you kiss. But my body had felt like lightning had struck it as we had kissed. Before the kiss, my heart was still pounding from feeling Z's tit. Now, it was pounding even harder in my chest.

Z moved to my right and turned her body, so it was at a right angle to mine to allow me to easily grab her butt. She turned her head to look at me and raised an eyebrow to remind me that I needed to answer her.

"Sure. It'd be good for us to practice that too."

Z gave me a pleased smile. "I love you, Eli. You make me feel so safe. There's no one else I'd practice with."

Z looked down slightly abashed. We didn't say anything for a few moments. It was like Z wanted what she had said to fully sink it with me.

"I love you too, Z." Z's silence had pressured me into saying that. I had told Z I love you several times before, typically when she was down, but this time felt very different.

Z said, "I enjoyed flirting with you last night. I had often wondered what it'd be like to flirt with you. I've never flirted with you like I flirt with my guys because you're my brother, but Katharine wanted me to demonstrate how to flirt and told me to pretend you weren't my brother. Did you enjoy flirting with me?"

"Yes." When I had gotten into the hot tub, it had been easy to block out that Z was naked. Now, I was very aware that my sister was naked under the water only a few feet away from me. "It has always made me mad when guys let you turn their brains to mush, but I now understand how hard it is to not be overwhelmed when you're pulling out all the stops. You know so many ways of pressing guys' buttons. Both you and Katharine. Both of you were driving me crazy. The other girls didn't come close to affecting me like you two did."

I grabbed Z's butt and squeezed. Z didn't show any surprise. Instead, she closed her eyes and tilted her head back a little as I continued to release and squeeze. Z's ass felt wonderful, so firm and full. My hand slipped around on her wet skin as I groped her.

Finally, Z opened her eyes, grabbed my hand, and pushed it away. "I'm not ready for you to do that, Eli. Maybe soon. Maybe very, very soon. But not right now."

Z's answer made me feel that we were drifting toward something. Everything so far I could rationalize as being acceptable for a close brother and sister to do. I had enjoyed the drift so far and was curious about how much farther Z wanted to go. But what were we drifting to?

Z moved to me and kissed me on the lips. This one was longer than the first thank-you kiss. Her warm lips felt wonderful on mine. This kiss was much more enticing, hinting at so much more we could do.

When Z pulled away, she said, "Thanks again, but I didn't respond well that time. I was much too slow to react. I think we need to practice some more. Use both hands next time."

Z moved directly in front of me and then turned around so her back was to me. She said over her shoulder, "I've given a lot of thought to your secret-boyfriend idea. At school, my secret boyfriend and I would continue to act as we always have. I'd tell my guys that I want to do their laundry to show them how much they mean to me and that I wasn't just toying with them. But doing their laundry would really be an excuse to spend more time in my secret boyfriend's dorm room. I'd start some laundry for one of my guys when I knew my secret boyfriend would be in his room without his roommate. That would be our time to be a couple. Even then, we'd mainly study with occasional hugs, kisses, and chatting about how much we loved each other. We'd play it very safe. No taking off clothes at school. We'd keep our passion burning at a low level until we could get safely alone."

Was Z proposing what I thought she was proposing? "Well, good luck finding a secret boyfriend."

Z stood and dove into the hot tub, flashing a bit of butt as she did. She swam down to the far end of the hot tub, popped up there, dove down under the water, and swam to the end of the hot tub to my left. When she got there, she climbed into one of the corner seats. She slumped down again, but not as much as before. I could see the top rise of her tits, with just how much depending on the bubbles of the jets.

Z said, "It'll be hard to find a secret boyfriend. He'll have to be a very special kind of guy. Someone who'll be able to accept that I was going to do what I wanted. Someone who trusted me completely. Someone who'd be totally committed to me, and I'd be committed to him. Someone who'd be my best friend, and I'd be theirs."

It really did sound like Z was proposing what I thought she was proposing.

Z dove into the hot tub again, swam to the far end, turned around, and headed back. As she did so, I thought over what she had said. It was a recapitulation of our discussion this morning. She was implying that I was her ideal boyfriend and she was my ideal girlfriend. I wanted to deny that, but it was what we had both said. I had certainly meant what I had said, and I felt she had meant what she had said.

When Z reached the end to my left, she turned to face me. She dropped down into the water before resurfacing close to in front of me with her head just above the water. She wiped the water away from her face and then moved toward me. I was still too stunned by her proposing we be secret boyfriend-girlfriend that all I could do was watch her. When her face was next to mine, she said, "I like kissing you." Z pressed her lips more firmly against mine this time. I could feel my resistance crumbling. This was our longest kiss yet. Kissing her felt so right, though I knew it was so wrong.

When the kiss ended, I said, "Z...We're--"

"You're already my secret boyfriend at school to a certain extent. We spend every Friday and Saturday night together. Our talks as we walk back to my dorm are the highlights of my week. All my good friends are your friends. When I flirt with your friends, I'm also flirting with you. When I stripped to half-naked after Dimitri gave me the bra, I was doing it for you as much as him. I wouldn't have put on those panties if you weren't out there. I wanted you to see me in them. I'm happy at school because of you. I want to change that only a small amount. It's only when we can get privacy like today that I want to change our relationship."
I realized that what Z had said was true; that I had been drifting into the secret boyfriend role for a while now. It had been so natural that I hadn't given it a thought, but it had happened. I had never considered hooking up on a Friday or Saturday night because I had a date with my sister. All Z was proposing was to accept what was already there.

Z kissed me again. As she kissed me, she grabbed my arms and then slid her hands down my arms to my hands. She slipped her fingers between mine and squeezed. We stayed like that for a few moments before Z ended the kiss.

"When I'm safely alone with my secret boyfriend, we'd make love and cuddle. My secret boyfriend would tell me that he loves me, that he thinks I'm wonderful and the best girlfriend ever. Lots of kisses and touches. There'd be a lot of sex, but also a lot of romance. When it was done, we'd have a feeling of love strong enough to tide us over until the next time we could be safely alone again."

Part of me longed for that. I wanted a girlfriend, Z was offering to be mine, and she was everything I wanted in a woman. And she was also my sister.

"Z, you don't think this would really work, do you?"

"Eli, you've forgotten groping practice."

Z kissed me once more, and as she did, she brought my hands up to her chest and placed them on her tits. They nicely filled my hands. Z kissed me more intensely as I squeezed her tits, feeling her hard nipples between my fingers. The pleasure was intense. This was heaven. Kissing a girl had never felt this good, this right.

After we had kissed for a good while, Z pulled away. She grabbed my hands and pulled them down. "I love you, Eli, but I am not ready for us to do that. I'm glad you want to touch me that way, but it's too soon." Z gave me a pleased smile. "I don't think we need to practice anymore."

"I agree." I took Z's last sentence to mean that now was the time for me to decide. But I wasn't ready yet to agree to be her secret boyfriend.

Z said, "I like kissing you. Do you like kissing me?"

Z moved her head toward mine. I couldn't resist. "Yes, I like kissing you."

Z kissed me yet again. As we kissed, Z resumed holding my hands, though more energetically this time. Sometimes she'd push my hand into a cup and put her hand into it. Sometimes she'd make a cup with her hand and push my hand inside of it. Eventually, I moved my hands with hers, making the cup and filling her cup without her prompting. We added to that, just sliding our hands over the other's. We constantly changed our grips without losing touch. It was very tame and at the same time very erotic.

I wanted to talk more, so I ended the kiss, grabbed Z's hands, and floated backward toward the corner seat closest to the Harringtons' bedroom. It felt good to straighten my legs after having them bent for so long. As I moved, I thought about what Z had said. She had followed a lot of the advice that Katharine had given during the flirting workshop. She had never explicitly asked me to be her secret boyfriend. It was still an abstract idea. She still had plausible deniability. And it was easier to discuss as an abstract idea. Z had also laid out in detail what she was expecting from me as her secret boyfriend and how she saw it working. With every other girl I had been with, I had had no idea of the kind of relationship I'd have with her when I first kissed her.

I let go of Z's hands and got up on the seat. Z stayed in the water facing me, putting her hands on my knees. I looked down on Z and said, "This secret boyfriend thing sounds crazy to me, like something out of a novel. You're beautiful, fun, and smart. You know how to flirt. Guys must talk to you all the time in your classes and your dorm. Why not one of them as a regular boyfriend?"

Rather than answer, Z turned around. She put her hands on my knees to press them together and then lifted herself into a sitting position on my knees. She leaned back so that her head was resting on the top of my chest. Her tits were now at the waterline, her nipples poking out of the water; bubbles regularly popped against them. Z grabbed my hands, squeezed them, and brought them to her sides.

"The only time I feel comfortable, the only time I feel like I can be who I want to be, is when I'm with you or Katharine. Yes, guys talk to me in my classes and at my dorm, and I know how to have a good conversation with them. But I never can read them well enough that I can feel comfortable in those situations. Sometimes I feel like I've said something wrong. Too often, I feel like they take what I say as approval to come on to me too strongly."

I could hear the frustration in Z's voice. I squeezed her hands reassuringly.

"Eli, this is what I want. This is what I think will make me happy and will make you happy. Don't tell me you're happy as you are now - not having any kind of romantic relationship. You want a girlfriend; I want a boyfriend; and we can't have a normal romantic relationship at school because of the life we've chosen. But we can still have a satisfying romantic relationship. I love you, Eli. Please tell me that you love me, that you want to be my secret boyfriend. Make me happy; make us both happy."

I couldn't tell her no after that. She had put all of her cards on the table, and they all made sense. I slid my hands under Z's and crossed our arms across her stomach. "I love you, Z." I gave her a light squeeze. "And I'd be proud to be your secret boyfriend." I added teasingly, "What do you want me to do now that we have some privacy? Kiss you?" I kissed Z on the cheek. "I like kissing you."

"More than that."

"Nibble on your ear?" I nibbled lightly on Z's ear. She shivered in delight.

"I like that. But I want more."

I teased Z some more with "Do you want me to whisper in your ear that I love you, that you're beautiful, and that I'm so happy being with you."

Z said huskily, "Yes, but more than that."

"Do you want me to ask you to do my laundry when we get back to the dorms?"

Z cracked up, and I joined in. I put my hands on the sides of her waist to help keep her balanced on my lap. When she stopped laughing, she said, "No. I'm not doing your laundry. I'm your secret girlfriend." I chuckled at that.

I moved my hands upwards, sliding along Z's smooth, wet skin. I also moved them forward so that they'd eventually cup Z's breasts. Z did nothing to stop me. Did I really want to take the next step? Did I really want to cross the line into being Z's boyfriend? I stopped my hands just below Z's breasts.

This would be such a dramatic change. But it was a change Z apparently wanted, and I was wanting more and more as we went along.

I decided to go slow, to give each of us a chance to back out. I said softly to Z, "I shouldn't do this." I brought my hands up to her tits, cupping them. They filled my hands. It felt magical to hold them. I hadn't realized how much I wanted to hold them until I was doing it. "But if you want me to do this, I'll keep doing this. Do you want me to do this?"

Z said dreamily, "I want you to do this. I love you, Eli."

"I love you, Z."

I squeezed Z's tits and then tweaked her hard nipples. I rubbed my hands in a gentle circle over Z's breasts as I gave her neck a little nip. Z began to slowly turn her head, so I moved mine to give her space. Z kissed me on the lips. It was a little awkward for her as she was turning her head so much. I moved my hands downward from her tits, sliding my hands down her sides. After a few kisses, she turned her head forward and pressed her cheek against mine. I slid my hands back up to her tits and squeezed them briefly, before starting another cycle.

We held that position for a while - Z leaning back on me, her cheek against mine as my hands roamed from her tits to her waist, getting used to her body. My becoming Z's secret boyfriend was a huge adjustment, so I wanted to slowly get used to touching her freely, and Z seemed fine with that. Z breathed deeply as she let me do what I wanted. The more my hands roamed, the more I wanted Z. How long had I wanted Z? From the time I saw her on the stairs? From the time she shook her sweet ass at me in the sexy panties Dimitri had given her? From before that?

I had fought it. I had thought she didn't want me, her brother. I had felt it was wrong. But now...now it felt so right.

I teasingly asked Z, "Is this all you want to do? Kissing and this?"

"I'm enjoying this. I'm in no rush. Touch more of me while we continue to sit here."

I brought my hands down Z's side, but this time instead of stopping at her waist, I kept going down the outside of Z's thighs as far as I could go. Then I moved my hands to inside Z's thighs. She opened her legs slightly for me. I brought my hands back up to squeeze her tits and to play with her nipples. When I moved my hands out to her sides, I twisted Z a little bit so I could kiss her on the lips for several seconds before starting the cycle again.

My desire for Z continued to climb. My cock was hard and erect. My little head was telling me that he wanted to have fun, that Z was the perfect woman to fuck. I was now ready to make the moves to make that happen.

I teasingly asked Z, "Is this all you want to do? Kissing and petting?"

"More than kissing and petting."

I swiftly brought my hands up and grabbed Z at the armpits. I lifted her out of the water and set her on the edge of the hot tub in the space between the two seats. I moved around her leg and brought my face to her pussy. I parted her lips and took a little lick. I looked up at Z. "Is this what you wanted?"

Z was leaning back resting on her hands behind her. She brought one hand forward and ran it through my hair. "I want this. I want this very much."

I returned my focus to Z's pussy. I couldn't tell much about her blondish bush because it was soaked. I wrapped my arms around her hips and parted her lips with my tongue again. I licked the bottom of Z's pussy, and she let out a loud groan. I couldn't tell how wet Z was because of the hot tub water, and the water also distorted Z's taste. I worked my way up, licking Z's pussy with the tip of my tongue. When I reached the top, I spent some time swirling around Z's clit. Z moaned and spread her legs more.

I moved back to the bottom and worked again up to the top. Z's breaths steadily deepened. When I got to the top, Z ran her fingers through my hair as I teased her clit. "That's it, Eli. That feels so good."

Leaving her clit, I slipped my tongue into her canal, lapping up the juices she was producing. Z had a tangy taste that suited her. Z put a hand on the back of my head, pulling my face closer to her as I fucked her with my tongue. Z moaned again. "God, yes, Eli! That's wonderful."

My face was getting coated with my sister's juices. I didn't mind as I knew I could wash them off easily. After a minute or two of tongue-fucking my sister, I moved back up to her clit. I felt like Z was sufficiently sexually excited, and it was time to make her come.

After a few licks of Z's clit, she suddenly pushed my head back. "I'm getting cold." She slid back into the water, came into my arms, and gave me a short, passionate kiss. "And I'm ready." I took that to mean she was ready to make love.

I lifted Z into one of the corner seats. "Young lady, you're going to come whether you like it or not." I kissed her as I brought my right hand to her pussy. I was glad she was so excited about making love that she wanted to do it now, but I wanted our first fuck to be the best that it could be, and I knew she'd enjoy it more if she came first.

Z spread her legs to give my hand better access. After I ended the kiss, she smiled at me and said, "Well, if you're going to put it that way."

I spread her pussy lips with my finger and went for her clit. I began rubbing the area around her clit. "Let me know where you like it best."

Z was already taking deep breaths. "Work all around for now. Later, just on the right side."

Z had her head pressed against the edge of the hot tub and her butt on the edge of the seat. Her tits were just above the water. I took her nipple in my mouth and sucked on it as I continued to work her clit. Z's breaths continued getting deeper. I could only reach her one tit, and I was working it over the best I could; sucking, kissing, and licking.

Z suddenly grabbed my head and pressed it hard against her chest. I felt her shudder. I continued working her clit as she came. A warm feeling came over me. I had made my wonderful sister come.

I moved my hand away from Z but kept my head pressed against her chest. She said dreamily, "That was wonderful."

"I'm glad I made you happy."

Z kissed the top of my head and then pushed me off of her. "There's another way I want you to make me happy..."

I moved out into the hot tub. "Oh really?" I asked teasingly. "What way would that be?"

"Your tongue felt good in a certain place earlier, but I want something else there now."

I grabbed Z's foot and guided myself around it, so I was now between her legs. "You want something else in your ear?"

Z giggled. "You didn't stick your tongue in my ear."

I put my hands on Z's legs and moved toward her. Part of me still couldn't believe this was happening, that this wasn't just a game we'd stop at any moment. Another part of me wanted me to stop, to not take the next step with my sister. I pushed those feelings away - Z and I had gone too far to turn back now. I had accepted that this was something both of us wanted and would make both of us happier.

Bending forward, I gave Z a quick kiss. Her face reflected the anxiety I felt - mild but definitely there. I assessed the height of my crotch relative to Z's and decided that they were close enough that this would work. I brought my cock close to Z's pussy. Z wrapped her hand around my hard-on and guided it toward her. Her hand felt amazing. My whole body shivered. This wasn't a hookup with some random girl. This was my sister, and this fuck would change our lives. I leaned forward and kissed Z as my cock entered her. "I love you."

"I love you, too."

Z locked her eyes on mine, and then pressed her feet against my butt, pushing me forward. We kept our eyes locked as my cock slowly slid forward into Z's slick vagina. Even though Z was well-lubricated, my cock felt a lot of resistance as it moved forward. Z's feet on my butt continued pressing me forward, and inch after inch entered her. Every inch felt like heaven. And then my crotch was pressed against Z's. I was buried all the way inside of my sister.

Z held me there and said, "That's it. I'm your girlfriend now. Make love to your girlfriend. And go slow, please. I want to savor this."

I slowly pulled back, enjoying the tight grip of Z's pussy on my cock. When only my crown was left inside of Z, I slowly pushed forward until once more my crotch was pressed against her. I pulled back and moved forward again. I really wanted to slam into Z but went slow as she requested. Going slow was sweet torture.

Z said, "Let me move over some."

She put her arms along the edge of the hot tub and moved off the seat into the empty area between the seats. Her head was resting on the tub edge, and her ass was floating free in the water. She was being held up by her legs that were wrapped around me. I was standing, with my upper chest out of the water.

I grabbed Z by the waist and slowly fucked her. Her eyes were closed, and her mouth formed a little 'O'. I slowly pumped my cock in and out of my sister. She moved herself down, so I bent forward a little bit and entered her at a slightly downward angle.

"That's it, Eli. Go slow and at that angle. That feels amazing."

Z felt amazing. I had always liked doggie style because I could grip the girl by the waist and fuck her like a bitch in heat. With me grabbing Z's waist, I had the same feeling of control, of power. But now, I could watch her beautiful face as I fucked her, watch her quietly moan out her pleasure on every stroke.

I sped up a little bit, and Z and I fell into a good rhythm. Z swung her hips forward as I thrust forward, both of us eager for me to fully penetrate her. The pool made a splashing sound every time I thrust forward and every time I pulled back. If anyone had been at home, they would have known what we were doing. This fuck felt very different from every other fuck I've done - fucking while standing in warm water, the water resisting my every movement. I'd always remember this fuck, for both who I was fucking and how different it felt.

"This feels so great, Z."

"This is the best, Eli."

I knew I was getting close to coming. I felt coated with sweat, and Z looked sweaty as well. I allowed myself to speed up. Every time I pulled back, I couldn't wait to thrust my cock deep into Z again. Z's feet were now down to the top of the back of my thighs. She was using them to goad me to thrust deeper and deeper each time.

Fucking Z felt so good, so right. I loved her, and I wanted to make her happy. And I was making her happy, in the most basic way. I knew this wouldn't be a one-time thing, that we'd make love again and again. We were committed to making each other happy now, in many different ways. But making love would be something we'd return to again and again.

And then I was coming. I plunged forward as far as I could, to get as deep into Z as possible. Pleasure filled my body as blast after blast of cum went into my sister. This felt so wonderful, so right. I drained myself into Z.

I stayed like that for a few moments, catching my breath. Then I grabbed Z by her upper back and pulled her upright next to me as I lowered us into the water. My mostly limp cock was still inside of Z. When Z's smiling face was right in front of mine, I said, "I love you," and gave her a long, sensual kiss.

When the kiss was done, Z said, "I love you too."

"This is where I usually cuddle and talk for a long time, but if we do that we'll turn into prunes."

Z giggled. "Let's get out then. You can cuddle me when you tuck me into bed at home. I'm feeling that I didn't get any sleep."

"Sleep with me tonight?"

"Yes!" Z gave me a big smile. "But in my bed, okay?"

"Okay."

"I'll look forward to it the rest of the day."

"Same for me."

* * * *

Z dressed quickly, but she made sure that Eli finished ahead of her. She said to Eli, "Spread the towels out on the deck to dry. You can put them away tonight."

As Eli did that, Z powered up the display of her phone which she had muted while preparing Bart's food. There was a short text from Katharine, Success?

As Eli put the cover back onto the hot tub, Z replied, Your plan worked perfectly.

* * * *

Z held my hand as we walked to the edge of the enclosed patio, but I dropped it there. "Security cameras."

As I walked to my car, I was filled with doubts and guilt. What the fuck had I done? I had wanted Z. I had been consumed with lust for Z. After all the flirting and groping of last night, I was ready to fuck almost anyone. Yeah, the sex had been great with Z. But now...I felt so stupid for giving in to my desire. This wasn't going to work. Being a pre-med student was death to relationships. Pre-med students didn't hook up because they preferred that to dating; they did it because they didn't have the time or energy to make a relationship work. When I inevitably broke up with Z, I'd hurt her badly, and I didn't want to do that. And then...she'd still be my sister. I'd still see her regularly at home. I'd still see her regularly for the rest of her life. And for the rest of her life, she'd be my ex-girlfriend. I didn't want that.

We got in my car and started driving home. I kept kicking myself for what I had done. A relationship without sex for months? Seeing each other every day and doing nothing more than hugging and kissing? That was nuts. I didn't know of anyone who had a relationship like that.
"Landon sent me this," said Z as she showed me a selfie of Landon on a mountain bike in the woods somewhere.

"Nice," I said after I barely looked at the picture.

What if after Z and I break up, Mom notices that awkwardness between us and asks Z what's going on? And Z tells her? What would my parents think of me? That I was some kind of monster?

A little bit later, Z showed me a pic Rob had sent her. I said, "Cool," after glancing at it.

Z asked, "You okay? You're very quiet."

"It's a big change." I felt like I shouldn't share my doubts. It was too late to say Maybe we shouldn't have done that.

"Yeah. It is." I felt Z could tell I was having doubts. "I should have told you that I have an IUD. So we don't have to worry about that."

I kicked myself yet again. I was so hot to trot that I forgot to ask an incredibly important question. Knocking up my sister would have been a disaster.

I felt like I needed to express my doubts to some degree. "Should we have talked about it more?"

"I don't think it's something you can discuss rationally; make a list of pros and cons about. We either loved each other enough to take that step or we didn't. "

We had taken that step. Time to try to make the best of it. I squeezed Z's hand. "I love you, Z."

"I love you, too."

The doubts and guilt were still there, but Z had beaten them back some. We were quiet for the rest of the drive to our house. Once we were inside, Z took my hand and together we went up the stairs to Z's room.

Z started stripping down. She said to me, "Take your clothes off," and I followed suit. I didn't know what was going to happen.

Z stripped to her panties and then put on the v-neck nightshirt from last night. "When Katharine bought this for me, I thought I'd only wear it at the workshop. Now, I think I might wear it regularly." Z gave me a coy smile.

I had stripped down to my underwear. Z pulled back the covers and got into her bed. I joined her. She guided me to lie on my back, and she put her head on my shoulder. She gave me a quick kiss on the cheek and said, "I love you."

"I love you too."

I started running my fingers through her hair. I hoped Z found it soothing. I did. Holding Z like this made me feel warm and happy. There was nothing sexual about it, only love. Suddenly, a loving relationship with very little sex didn't seem so far-fetched.

Could we have done a trial run of me being her secret boyfriend? Just doing kissing, hugging, and this? See if we liked it and could handle the secrecy?

I thought about it for a little bit and decided it would have been worse than what we had done. Z and I were both sexually experienced. A G-rated relationship would have felt very shallow, and one of us saying that we didn't want to continue would have been as painful a rejection as if I were to say that now.

It didn't take Z long to fall asleep. I cuddled with her until I started feeling painfully stiff. I slowly slipped out of bed, managing to keep Z asleep. I pulled up the covers over her. I gathered my clothes and quietly exited her room.

* * * *

I called my best friend from high school Seth and asked if I could come over. We talked for a while, went out for lunch, and then went back to his house to talk some more. Seth was pissed about spending a week at home. He had a girlfriend at college and hated being apart for a week. They were serious, but not serious serious. He hated being back in our smallish town and felt trapped in a cage. He loved being what I considered to be a normal student in the dorms, so home held no appeal for him. I was thrilled to be home. I loved getting totally away from my pre-med studies. Saturday night, Dad and I had spent several hours in a remote field studying the heavens. That was something I couldn't do at college. Then last night was the flirting workshop. And this morning...

Around four, I headed home. I doubted I'd visit Seth again. We had once been so close but now were too different.

Z was in the shower when I came home. It felt very weird to step into the bathroom while she was in there. It was something so forbidden that it was hard to break the taboo. Z gave me a wet kiss, and I went downstairs to wait for her.

When Z came down, we sat on the couch together holding hands. I told her about my visit with Seth. We talked about our plans for the evening. After dinner, I'd go over to walk Bart, and Katharine would come here to visit. Z emphasized that we need to keep on our typical schedule - no spending extra time together. We talked about what we felt was safe to do tonight after Mom and Dad went to bed. Mom and Dad almost never came upstairs. A family joke was that they'd board up the stairway when Z and I moved out for good. But Z and I decided to play it safe and make no rhythmic bed sounds that they may be tempted to investigate.

On a weekday, Dad usually got home a little before five. With Mom covering all of Dr. Harrington's appointments, she'd work until all the patients had been seen however long that'd take. When Dad got home, I was reading my book in the living room. Z was upstairs.

"Hey, Eli! Play some pool?"

"Sure."

As Dad and I played pool, we talked about our days. Needless to say, I didn't tell him that Z and I had awesome sex in the Harringtons' hot tub. But I did wonder how he would react if I did tell him. Throw me out of the house? Make me promise to never do that with Z again? Call the cops?

After fifteen minutes of playing pool, Dad said, "Time to start on dinner." He did most of the cooking.

"What are we having?"

"Eggplant parmigiana." Z's favorite dish.

"You want help with that?"

"Sure."

Dad got out the recipe, and I started getting out of the ingredients. Dad asked me, "Where's Z?"

"Upstairs."

"Doing what?"

I made a 'who knows' gesture.

"How are you two getting along at college?"

I fucking hated lying to my dad. "Okay. She's friends with a few of my friends. I see her regularly, but I'm so busy studying that I don't have much time to talk with her."

"Good to hear. Your mom was afraid she wouldn't make friends at college. She's glad you're there to take care of her."

Man, I felt like dog shit. Mom should have seen me taking care of Z this morning.

I got all the ingredients out and opened all the cans. Having done all I could, I went back out to the living room and read my book. After a while, Dad came out, and we played pool. While we were playing, Z came down. She told me the latest she had heard from Landon and Rob.

After a while, Dad said, "Time to for the next step of the eggplant parmigiana." Z and I trooped behind him into the kitchen. Z and I breaded the eggplant slices, and Dad fried them. Z and I hung out in the kitchen with him as he finished getting the eggplant parmigiana ready to go into the oven. He'd pop it in when Mom called to say she was heading home.

Dad and I resumed playing pool. Z went upstairs. After a while, Mom called Dad. I went into the kitchen and put the eggplant parmigiana into the oven. Dad came in and pulled out a bottle of wine from the small wine rack on the counter. He said, "I think some red wine for tonight," as he proudly displayed the bottle. He gave me a wink. As he grabbed wine glasses, he said, "I think you and Z are old enough to have a glass too."

Dad and I played pool until Mom came home. She staggered through the back door. "God, what a day. I'm exhausted. I'm ready to collapse."

I happened to glance over at Dad, and he was crestfallen. I guessed he was hoping to get lucky tonight and now knew it wasn't happening.

Z came downstairs, and the family moved to the kitchen table. We made small talk until the eggplant parmigiana was done.

After a few bites, I said, "This is incredible, Dad. Thanks so much for making it."

Z added, "Ditto. It's so great to have your cooking after having to subsist on dorm food."

Dad gave us his aw-shucks look.

I stuffed myself silly and then went over to take Bart on his walk. As we walked, I told him about Z and me, and how I already hated hiding our relationship from our parents. Bart's message for me was to stop bitching and smell the mailbox posts.

* * * *

At 9:30, Z and Katharine came down the stairs. I took a break from playing pool with Dad to talk with Katharine.

"Hey, Katharine."

"Hey, Eli. Bored out of your gourd yet?"

"How could I be bored with you in town?"

Katharine smirked. Z left us and headed toward the couch where Mom was. Katharine moved her head to indicate she wanted us to move to the 'back hallway'. Once we did, she turned serious and said quietly, "Remember - not a word about last night."

I nodded. Keeping my voice low, I added, "I visited Seth this afternoon and didn't mention it." I gave Katharine a grin. "If I had told him that you told me to cop a couple of feels and then you frenched me, he wouldn't have believed me."

Katharine gave me a big smile. She grabbed a strand of her hair and started twisting it around her finger. She looked slyly at me and said, "If you get me alone sometime, I may let you do more." She gave me a coy look. "Does the no-dating edict of this morning apply to me too?"

I knew she wouldn't date me and was trying to bait me into asking her out. I said, "What I learned from last night is to let you do what you want to do."

Katharine laughed a deep, sexy laugh. It was more a come-on than an expression that she found what I had said funny. She arched her eyebrows and said, "What if what I want to do is to break your heart?"

"You've broken it a thousand times already. What's one more?"

Katharine gave me a warm smile like I had passed a test and she was giving me her approval. She then gave me a quick kiss on the lips, walked to the door, said bye to Z, and left.

Z was sitting on the couch with Mom and watching whatever show she was watching. I looked at Z as I walked toward the playroom to make sure she was okay with my flirting with Katharine. She smiled at me to let me know she was okay with it. In the playroom, I picked up my cue and started sizing up the table.

Dad asked, "What was that between you and Katharine?"

"We were just saying 'Hi'."

Much better for Dad to be wondering what was going on between me and Katharine than to be wondering what was going on between me and Z.

* * * *

At ten, Dad announced, "Time for bed." Mom turned off the TV. Z headed upstairs. Dad put his pool cue up and walked over toward the couch where Mom was now standing. "How are you feeling, Honey?"

"Refreshed after such a marvelous meal." Mom kissed Dad and then walked with a little swing in her hips to their bedroom. Maybe Dad would get lucky tonight.

I wanted to rush up the stairs to Z's bedroom. Even with Mom and Dad gone to bed, I knew I shouldn't do that. They'd hear my footsteps on the stairs. What did I normally do in this situation? I disliked having to think about what was normal. I wanted to give Mom and Dad plenty of time to settle down for the night before going to Z's bedroom. I decided to eat some ice cream.

* * * *

At 10:30, I walked as quietly as I could into Z's bedroom. She was already in bed. She pulled back the covers for me to join her. She was wearing her V-neck nightshirt. I was wearing my usual sweatpants. I kissed her, and we started talking.

Z said, "I was totally fine with you flirting with Katharine. It's what you normally do, and we have to keep things normal."

We continued talking and kissing. Then mostly kissing as our hands roamed. Z tossed the nightshirt. I lost the sweatpants. I removed Z's panties and then ate her out while trying to make no noise. I wanted to fuck her. I wanted to fuck her until she screamed out my name. But instead, Z quietly gave me a blowjob. She was inexperienced, but I came and she swallowed, so a good blowjob in my book.

I had actually liked that Z had been inexperienced about giving head. This was about love, not sex. If it was about sex, it wouldn't work. Z had done what she thought would make me happy because she loved me. And that made me love her even more.

After lots of kisses and I-love-you's, we both got on our left sides and Z spooned against me. I was naked and she was wearing her panties. Her skin felt so good pressed to mine.

A lot of the doubts were gone. Mom and Dad tonight had reminded me of when I had dated Tracie - I had almost never been in the mood during the middle of the week. I was just mentally and emotionally exhausted from studying. I felt bad about that. Now with Z, I wouldn't have to worry about that. When I was working my butt off, we couldn't have sex. But when I was away from school and ready to make up for lost time, Z would be there for me.

It was worth it; all of the lies and misleading of my parents. I didn't like doing it, but it was the price of heaven.

* * * *

Tuesday morning, Z woke up first. She normally took the first shower. I went across to my room and dozed in my bed while Z showered.

After we had taken care of Bart, we went back to our house and Z's bed. We cuddled and kissed; made love; cuddled, kissed, and talked; and then had a long, slow lovemaking session. When we were done, I was totally satisfied. I laid on my back with an arm around Z, who had her head on my shoulder.

"I love you," I said.

"I love you too."

"I could definitely get used to this. Sadly, we won't have too many more chances to do this before we go back to college."

"True, but I didn't wanted to be your girlfriend for the sex. The sex is great, but the feeling of being loved by you is far more important to me."

I kissed Z's forehead. "And the feeling of being loved by you is the most important thing to me."

Z kissed me. "We shouldn't spend all day in bed. Katharine has some adventure in mind."

"Okay."

* * * *

After lunch, I went to Walmart to look for Christmas ideas. I ran into Giselle there. She was wearing jeans, a loose sweatshirt, and a baseball cap. It was like she was playing down her good looks.

"Aren't you Z's brother?" she asked me, feigning to barely know me.

"I am. You were at the sleepover Sunday, weren't you? I only saw you for a moment."

"I was. Z said you were a pre-med student."

We pretended to introduce ourselves. Giselle had also come to Walmart to Christmas shop. We wandered around the store, bouncing ideas off each other. I had the feeling, that like me, she was more killing time than Christmas shopping. She told me about her family and her dogs. I told her about my parents. We talked about college. Giselle was a pleasure to talk with; someone I instantly trusted.

When we had seen all we wanted to see in Walmart, we drove over to McDonalds, ordered a snack, and ate it in my car.

"Thanks again for doing the flirting workshop," said Giselle.

"It was a lot of fun. At least for me."

"I wouldn't say it was fun for me, but it was very interesting. Katharine makes flirting look so easy, and it was quite eye-opening to hear how much thought she's put into it." After a pause. "And it was fascinating to see how much Z has changed. In high school, she had been a quiet nerd; okay to talk to one-on-one but didn't say a word in a group. Now, she's much more outgoing and self-confident. I could never pull off flirting like she did in the workshop." Giselle sighed. "Z has grown so much. I'm envious."

That made me feel good. Yes, Z had grown so much. Now, she was beautiful, confident young woman and a great secret girlfriend.

Giselle added, "And Katharine has grown so much too."

I was surprised by that. "What do you mean?"

"Sunday, Laurie, Katharine, Z and I went to the mall. On the ride, Katharine was very different than she had been in high school. She was so much more thoughtful and considerate. One the ride, she was funny and having a lot of fun, which wasn't too different than high school. But so much of that was playing off of Z. They're such close friends, and you can tell they both think the world of each other. Katharine had no close friends on the cheerleading squad. Occasionally, Z would say something to Katharine like 'We need to include Laurie more' and 'It's Giselle's special day', and Katharine would change how she was acting. It was like she trusted Z to be her conscience, that she wanted to act in a way that Z would approve of."

I had seen enough of Katharine and Z together to verify what Giselle was saying. "Z does think the world of Katharine."

"Tomorrow morning, I'm having them over to my house. My parents do not like Katharine. They're close friends with Becki Davis' parents, and Becki told them every bad story about Katharine that she could. After I broke up with my boyfriend, Becki called me a couple of times. It was all 'he wasn't part of God's plan for you' bullshit that didn't help at all. Katharine told me that I was better off without that loser, and she'd teach me at Thanksgiving how to get a much better boyfriend. She got me to laugh, and she boosted my spirits far more than anyone else. So tomorrow, I'm telling my parents that Katharine and Z are good friends of mine that I'm going to spend time with, whether they like it or not."

"I hope all three of you have a good time." It was surprising to me that Z and Katharine had earned such backing from Giselle.

"Valerie is still majorly bummed you said you wouldn't date her. She really wanted to date you. She'll be even more bummed when I tell her about us spending the afternoon together."

"There wasn't enough time to make it work. And there was no guarantee she could have gotten free to see me."

"True. She wanted me to lie to my parents and hers, and I didn't want to do that. Thankfully, you saved me from that." Giselle sighed. "Speaking of my parents, I need to get home before they start wondering what happened to me." Giselle gave me a warm smile. "It was great talking with you, Eli."

"It was great talking with you."

Giselle got out of my car and got into hers, and then I drove home.

* * * *

That night, I was up in my room reading when I heard door slams. Mom and Dad were already in bed. I came down the stairs to see Z and Katharine coming in the front door.

"Hey, Z. Hey, Katharine. What have you two been up to?"

Katharine said, "We went to the mall. I bought Z some things at Victoria's Secret. And then we talked about how she could let your friends 'accidentally' see her in them."

I looked over at Z, and she was blushing. I turned back to Katharine. "Did you buy anything for you?"

"A couple of things," she said coyly. "I already have so much."

"Let me know if you ever want to model them for me. I'd be happy to give you my opinion on how you look in them."

Katharine made a face like she had bitten a lemon. "Modeling lingerie for a guy? How droll. That wouldn't be any fun." She moved closer to me and said quietly, "Lingerie is for teasing, not modeling. Giving a guy a peek will drive him nuts far more than giving him a full view. And if he thinks you're accidentally letting him see it..." She gave me a knowing smile and then moved even closer and whispered in my ear. "Like wearing thong panties under a short nightshirt and then standing on stairs above him."

My eyes went wide at discovering that Katharine had known all along.

Katharine kissed me gently on the lips. She sultrily, "Goodnight, Eli." Then she turned to Z and said brightly, "'Night, Z."

Once Katharine left, Z and I went up the stairs to her bedroom. I asked, "Are you going to show me what you got?"

"Not tonight. Katharine has it. She's holding it hostage, so I'll see her again before we leave."

"Well, you'll see her tomorrow." I told her about running into Giselle. "Don't spend too much time at Giselle's tomorrow. Tomorrow afternoon is our last chance to make love before Christmas break."

Z kissed me. "I know. Don't worry. I'll be back in plenty of time. I want our last time to be special. Now, go change into your sweatpants."
I changed into my sweatpants. When I got back into Z's bedroom, she was wearing her V-neck nightshirt. We got into bed. Z had me lie on my back so she could put her head on my shoulder. We kissed and cuddled for a while, and then Z moved to on her side and I did the same. She spooned against me as I held her close. No oral sex tonight, which I was fine with as I was still satisfied from this morning.

As I held Z, a warm happiness filled me. After almost two days of being lovers, I had come to realize that I would always feel guilt and doubt; that there would always be moments of awkwardness and frustration. I needed those, so I wouldn't do anything stupid and reveal our secrets. There'd always be the chance that our relationship would fail, and then we'd have an awkward breakup. But I was glad we had taken this step. The only way to know if our relationship would work was to try it. What-might-have-been was very unsatisfying for Valerie. If I had said no to Z, I think I would have found that decision equally unsatisfying. Now that we had embraced our love for each other, I had never been happier.

* * * *

The next morning, Z went to Giselle's after we had taken care of Bart. I envied her having friends at home to spend time with like Katharine and Giselle. Having talked with Seth, there wasn't anyone else I wanted to spend time with. I read for a while and then took a nap. It was nice to nap, to do nothing instead of studying. Yeah, it'd be nice to spend time with friends, but it was also nice to recharge my batteries by lazing around the house and making love to Z. I needed to recharge because, once I got back to school, it would be work, work, work until finals were done. Yes, Z and I wouldn't be able to make love while we were back at school, but I wouldn't have time to do so anyway.

A little after noon, I get a text from Z. Katharine wants to come in and say hi.

I was waiting by the door when Z and Katharine came in. Both of them were wearing a long sweatshirt and jeans.

"Hi, Z. Hi, Katharine."

Katharine came over and took my hand. "Hi, Eli." She drew me over to the stairs. Our stairs had a flared bottom. Katharine got on the first step off the left of center and turned to face me. She positioned me on the floor in the middle of the stairs. "Did you miss me?"

"Not really." I had seen her last night.

Katharine laughed while keeping hold of my hand. Z stepped onto the first stair but to my right. Katharine said, "Z and I are wearing the same outfit." She smiled at me.

That made no sense. Yes, they were wearing sweatshirts and jeans, but the sweatshirts and jeans were different.

Katharine put her hands on my shoulders and kissed me. It was similar to the other kisses she had given me since the flirting workshop, but I wasn't comfortable with her being this affectionate with me in front of Z. Katharine seemed to be enjoying my discomfort. She said, "At one point late, late Sunday night, I was planning on not leaving Monday morning. Once Giselle and Laurie left, I was going to take you upstairs to your bedroom and fuck your brains out."

I had no idea why Katharine was telling me this. I decided to brush it off. "Wouldn't have worked. I had to go feed Bart."

Katharine laughed again while keeping her hands on my shoulders. She seemed to be laughing at the thought that I'd be able to resist her. "Z could have handled feeding Bart by herself for one day."

Katharine kissed me again, this time a few seconds longer than a friendly kiss on the lips. Would I have turned her down if Monday morning she had taken my hand and said Let's go upstairs? Almost certainly not.

I asked, "Why didn't you?"

Katharine smiled at me and then gave me an even longer kiss. Damn, she was hot. She had me rock hard. I couldn't wait for her to leave so I could go upstairs with Z. But Katharine seemed in no hurry to go. She said, "You know." I didn't. She gave me a short kiss. "Since Monday morning, have you been kissing anyone but me?" She gave me a coy look.

"No. I've only kissed you."

Katharine laughed once more. "A handsome young man like yourself should be doing more kissing than that." With her hands on my shoulders, she twisted me toward Z. "Like with your sister."

Z moved toward me. "Katharine knows all about us." Z put her hands on my shoulders as Katharine withdrew hers and then kissed me.

"You have me to thank for Z being your girlfriend," said Katharine. "She never would have done it without me pushing her."

Shock and disbelief came over me. Katharine knew about Z and me, and Z was fine with that? I didn't want anyone to know. Our love was the deepest, darkest secret imaginable to me. Z was my girlfriend because of Katharine? Z was my girlfriend because I had found her irresistible in the hot tub.

Z kissed me again, a few seconds longer than the first time. I didn't respond at first, but I gradually returned the kiss. Kissing Z felt so good.

Katharine continued, "After a couple of weeks of movie nights, I noticed Z was talking differently about you. She talked about Dimitri, Landon, and Rob like they were really nice guys. But she sounded all dreamy when she talked about you."

While Katharine had been talking, Z had given me a longish kiss and a short kiss. She said to Katharine. "I think we're caught up." She turned me toward Katharine as she said, "I had no idea I was exposing my feelings toward you. Or that I had feelings toward you."

I was still a little bit in shock, but my disbelief was wearing off. I had known that Z and Katharine were close, but I hadn't appreciated how close. They were working hand in glove now. I would have thought that Z wouldn't want me to kiss anyone, but she was obviously on-board with Katharine kissing me now. Suddenness of everything was jamming all my mental circuits.

Katharine kissed me. I hated to admit it, but she was a better kisser than Z. When she kissed me, hormones started flooding my system. Katharine looked me in the eye. "I'm an evil person, and the idea of bringing a brother and sister together thrilled me to no end." She kissed me, slipping her tongue into my mouth. I knew now that if she had wanted me Monday morning, there was no way I could have resisted her. She was too damn sexy and knew too well how to press my buttons. Part of me thought I shouldn't be doing this in front of Z. But as Z obviously approved of what I was doing with Katharine, that objection was easy to ignore.

When Katharine was done kissing me, Z put her hands on my shoulders, and I turned to face her. As the girls were only a few feet apart, it was easy to face one and then the other. Z kissed me. I heard Katharine unzipping something. The girls were far enough apart that I couldn't see one while I was kissing the other.

Katharine said, "So I came up with the idea of a flirting workshop. It seemed like the perfect thing." I could hear Katharine doing what sounded like pushing down her jeans. "If Z's feelings toward you were like I thought, she'd be so jealous that I could talk her into admitting she loved you and should make a move on you." It sounded like Katharine was pulling a leg out of her jeans. "And you'd be so horny from all the flirting that you'd offer her little resistance."

While Katharine was talking, Z was kissing me. At one point, I put my hands on Z's waist with the intention of bringing them up to her tits. Z pushed them off her. Then she slipped her tongue into my mouth and we Frenched. I realized that Z was mirroring what Katharine did. This kissing session went longer than what I had done with Katharine, but Katharine apparently needed the extra time to take her jeans off.

Katharine continued. "The flirting workshop got off to a great start. I heard you coming around to come up the stairs. I wanted to give you a long look at your hot sister. I was fine with Valerie going braless, but I knew having her try on the sleep shirt braless and with a bra would give you lots of time to check out your sister. And then I stretched things out by talking to her about basketball. I loved giving you a show. I was sure Z knew you were down there, and I was happy to see her going along with giving you a show. It gave me a lot of hope for my plan."

Z pulled back. When she turned me toward Katharine, I couldn't help noticing that Katharine was wearing white stockings that were attached to garters that came out from underneath her sweatshirt, which was now pulled down to over her hips. Katharine was smiling at me when I finally looked up at her face. She said, "Still no touching, only kissing. I'm having a great time." She put her hands on my shoulders and guided me into another French kiss. I realized that I wouldn't be able to touch Z's wonderful body until Katharine let me touch hers. Would she let me?

Z picked up the story by saying, "And boy, was I jealous." I could hear her unzipping her jeans. "Especially of that stupid bitch Valerie. Who was she to come on so strong to you?" I heard Z taking her jeans off. Z didn't say anything for a while as she wrestled with her jeans, while my tongue wrestled with Katharine's. "It was really hard for me to stay pleasant and helpful toward her. Giselle and Laurie bothered me, but not nearly as much as Valerie. I was really glad you didn't grope her during that last session."

The shock had worn off now. I was seeing how Katharine had been behind Z and me getting together, so, of course, Katharine knew about us. Z seemed confident that Katharine knowing wouldn't be a problem. As I trusted Z, I was content now to go along with whatever she and Katharine had planned.

Katharine ended the kiss and turned me toward Z. Z too was wearing white stockings that were attached to garters that came out from underneath her sweatshirt. Katharine said, "I told you Z and I were wearing the same outfit. Or more accurately, the same lingerie."

Z pulled me toward her and gave me a passionate French kiss. It was so hard to keep my hands by my sides. I wanted to explore under that sweatshirt. What was the rest of the outfit she and Katharine were wearing?

Katharine grabbed my belt and undid it. "I had told Z I was going to give you a big kiss at the end of the workshop, but she didn't pass that tidbit along. I think she didn't want me to do that." She unzipped my pants. "I really enjoyed kissing you. You were marvelous during the workshop. All the girls wanted you. And I got to kiss you in front of them all." Katharine let out another evil laugh.

When Z stopped kissing me, Katharine turned me so I faced away from the stairs. Katharine said, "Kick off your shoes." I kicked them off. Katharine turned me so I was facing her. She said, "Last time of no hands." And then she was French kissing me.

Z said, "After the workshop, all of us girls talked for two more hours, and then we settled down to go to sleep." Z grabbed my jeans and started pulling them down. "When everyone was asleep, Katharine woke me and said to come with her. She told me that she wanted to talk to me about you." Z had pulled my jeans down to my ankles. She helped me step out of them as I continued to kiss Katharine.

Katharine suddenly ended the kiss and twisted me toward Z. I guessed that Katharine wanted to tell this part of the story. She grabbed my T-shirt and pulled it over my head, leaving me in front of Z with just socks and underwear on. Katharine said, "I started by saying how wonderful you were that evening. And Z lit up."

Z smiled at me. It just melted me. I loved her so much. We kissed.

"To me," said Katharine, "it was obvious that she was crazy about you. We talked about you for quite a while. And then I said I was thinking of making a move on you, but I didn't want to do it if Z didn't agree to it. I liked you, but not enough to hurt my friendship with Z. But if Z was okay with it, I'd stay after the other girls left, and then I'd go up to your bedroom with you."

Z and I continued to kiss after Katharine stopped talking. This kiss was less passionate and more tender. I thought over what Katharine had said. This must be what she was talking about right after she kissed me the first time.

When the kiss ended, Z turned me toward Katharine. Katharine said, "Hands only on the outside of the sweatshirt and only in the back." I put my hands on her ass as Katharine put her hands on my shoulders. She moaned lightly as my hands gently roamed. Katharine kissed me.

Z said, "We talked about how the workshop went after that. But the whole time, I felt worse and worse about agreeing with Katharine going off with you. I eventually told Katharine that I'd prefer that she not pursue you, that it would upset me if she did."

Katharine and Z's bodies looked very similar with them dressed as they were. Katharine was probably an inch taller than Z's 5'8". As Z had talked, Katherine had alternated kisses and small moans. Even through her sweatshirt, her ass felt fantastic in my hands. How much further would this go?

With the way Z had stopped, I could tell it was time for Katharine to continue the story. I moved on my own to Z. As I was moving, Katharine said, "That was when I told Z that I thought she was in love with you."

Z gave me a quick kiss and said, "I, of course, denied it. I loved you only as a brother." She kissed me. My hands went to her ass. Through the sweatshirt, it felt the same as Katharine's. As I was familiar with Z's behind, I could have been more aggressive than with Katharine, but I decided to gently rub Z's ass as I had with Katharine.

"I told her that I was her best friend," said Katharine, "and she could tell me anything; that I wouldn't judge her."

Z stopped kissing me to say, "I still denied it." And then we went back to kissing.

"I told Z that instead of arguing about whether she was in love with you or not, let's discuss what would happen if you and Z were a couple. I asked her to imagine what it'd be like if you were secretly a couple when you returned to college."

Z stopped kissing me, so I turned to Katharine. Katharine said, "Hands can go under the sweatshirt, but only in the back and only below the waist."

I put my hands under Katharine's sweatshirt and immediately felt bare ass. She had no panties on! I said to her as I squeezed her ass cheeks, "I like your panties."

Katharine gave me a knowing smile. "Then you'll love the matching bra."

I laughed and then kissed her. I still didn't know what was going to happen, but I was guessing the sweatshirt was going to come off, and I'd see Katharine in only a garter belt and stockings. What would happen after that?

Z said, "I told Katharine about you saying that I needed a secret boyfriend. I meant it as a joke, but then I realized that having you as my secret boyfriend would work perfectly. The more we discussed it, the more I wanted it. Once I started talking about having you as my boyfriend, I realized that Katharine was right; that I was in love with you. But I didn't think you were in love with me. I thought you'd make a date with Valerie. And even if you didn't, you would reject any kind of advance from me."

Katharine and I were kissing hot and heavy as I squeezed her marvelous ass. Her body was lightly pressed against mine. It was like a dream come true. How many times had I wished I could do something like this with her? How many guys at my high school had wished they could do something like this with her?

Katharine broke off the kiss and said, "When I thought of this, I didn't imagine it'd be this good."

Z said tartly, "So you admit that you were the one who thought of this."

Katharine replied, "I had thought of this before you brought it up. But you were the one that brought it up."

Z put her hand on her hip. "After you dropped some big damn hints that you wanted to do this."

I grabbed Z and kissed her. I didn't care to hear the girls argue. It sounded like this was an ongoing argument with no resolution in sight.

Z put up a little resistance when I first started kissing her, but she quickly got into it. Over and over, I'd put my hands on the back of her upper thighs and then slowly bring them up to her ass where I'd cup her cheeks, give them a little rub, and then a final squeeze before dropping my hands down again. I had some familiarity with my sister's body, but I still very much enjoyed exploring it. I was so ready to fuck her. I didn't know if I'd fuck Katharine, but I knew I'd fuck Z, and I was eager to do so again.

Katharine said, "I told Z to not give up hope. I told her that Valerie had been making all the advances and that you were just going along. I told her that Valerie was being too easy, so I thought you'd pass on her. You hadn't shown any interest in Laurie, and Giselle was a long-term investment that you wouldn't have the time for. I suggested we plan how Z could seduce you, and just hope that she'd get the opportunity to do so. We brainstormed how to do it in this house, but I felt like there weren't any good ways to lead you on here as you two had spent your whole life here. Z brought up the Harringtons' house, and when she mentioned their big hot tub, I thought it would be perfect. I coached her on how to bring up the hot tub, how to get the two of you naked into the hot tub, and what to do after that. We probably talked a good two hours about it."

Z pulled back from me and said, "And it worked. And it was wonderful. It was absolutely incredible." She kissed me again, then turned me toward Katharine.

When I got to Katharine, her arms were in the air at like a 45-degree angle from her body. She said, "Time for the unveiling."

I grabbed the end of each sleeve and pulled the sweatshirt slowly up her body. As the bottom rose, Katharine's pussy came into view. I expected Katharine to have a shaved pussy, but she actually had a good size bush. Dark brown. A few moments later, a white garter belt came into view. Then Katharine's firm stomach. The sweatshirt stuck on her boobs for a moment, and then slipped upward suddenly, revealing them in all their glory. Her boobs bounced a couple of times once they were freed. They were large; larger than Z's, and I found Z's tits wonderfully large. Would the girls let me touch them? I very much wanted to.

The sweatshirt finished coming off quickly after that. I tossed it aside and moved toward Katharine.

"Hands stay in back below the waist," said Katharine. "You can press your chest against mine, but don't press too much." She gave me a wicked grin. "We're saving the good stuff for when we go upstairs."

Katharine kissed me, wrapping her arms around my neck. My hands naturally found their way to her ass. Katharine's large boobs pressed firmly against my chest. I loved the feel of them. I had thought before that our kissing had been hot and heavy, but it was scorching now.

Z said, "Before we were done, Katharine had texted me asking if I had been successful. I didn't see any point in lying to her. I told her how great it had been. How you had started telling me 'I love you' right away. I told her about how I fell asleep on your shoulder. That I felt like I had made the right decision. And I was very, very happy." Z reached out and stroked my back.

It was really weird to be madly making out with Katharine while Z talked about how hard she and I had fallen for each other. Where was this going? Why was she okay with Katharine and I making out like this?

Z said, "And then Katharine started talking about how I should reward her for talking me into trying with you. And then Katharine started kissing you and flirting hard with you, in case I wasn't bright enough to pick up on her hints."

Katharine pushed me away and turned me toward Z. "We wouldn't be having this discussion if you hadn't made me promise to not have sex at college."

As Z raised her arms like Katharine had, she gave Katharine a disgusted look. "I had you promise that you'd wait to have sex with your boyfriend. How was I to know that you'd only want to date guys at college?"
I grabbed the end of Z's sleeves and started pulling the sweatshirt off of her.

Katharine said, "You know I'm terrible at relationships; that I much prefer dating to having a boyfriend."

Z's blond bush came into view and then her garter belt.

"Which is why I made you promise that you'd wait until you had a boyfriend to have sex," said Z tartly. "That was to encourage you to work on getting better at relationships."

"If there were more guys like Eli, I'd have a boyfriend. Eli is not one of those idiots that, when I talk to them, act like a girl has never talked to them before." Katharine's voice had turned bitter. "Or even worse, one of those guys who think that because I show the slightest bit of aggressiveness that 'I want it', and it's their rightful duty to give it to me."

I continued raising Z's sweatshirt as Katharine paused for a bit. Z's tits came bouncing out of it. They were marvelous tits that I loved to feel and suck on.

Katharine said almost tenderly, "He understands that I'm just having fun. That all of the girls last night were just having fun. That us flirting with him was a compliment; us showing interest in him; us opening a relationship with him to see what he'll do with it."

I finished pulling the sweatshirt off Z. Katharine pushed me toward her. "Go kiss your sister." I almost laughed. Then I was next to Z. I took her hands in mine and looked into her eyes for a moment. All I saw there was love. I kissed her, feeling the love she had for me through her mouth and tongue. My hands slipped down to her ass. Z pressed herself firmly against me, much more so than Katharine had done.

"Hate is not the opposite of love," said Katharine. "Apathy is. Flirting is the opposite of apathy. It pisses me off so much that people can't understand that."

I continued kissing Z. My interest in what Katharine was saying waned. I wanted to pick Z up in my arms, carry her upstairs, throw her down in her bed, and make love to her. Again, I had no idea how Katharine fit into Z's plans for this afternoon.

"Anyway, Z and I have been having lots of disagreements about who said what when. Eventually through all the misunderstandings and miscommunications, what we agreed upon was that this afternoon, you and Z would have sex per my directions, and then you and I would have sex per her directions. I had already promised to never tell a soul about you and Z. But in return for her inviting me into your bedroom, I'll double-cross-my-heart promise to never tell anyone about you and Z, and I'll stop giving her grief about a bunch of minor shit."

So that was what the plan was. Wow! That explains why Z was willing to let me make out with Katharine here at the bottom of the stairs. This has been just a warm-up. But this had been all decided on by the two of them.

I broke the kiss with Z. I found her hands with mine and turned toward Katharine. "Does Z know what you're planning on directing us to do?"

"Yes." Katharine smiled evilly. "I've already told her exactly what I want her to do. She's been vague about what she wants me to do."

And then Katharine giggled. She said to me, "Stay there." She started up the stairs, and Z went with her. They went two-thirds up the stairs and stopped. They struck poses like they had on the night of the flirting workshop. Their legs looked great in the white stockings, and the garter belts perfectly framed their asses.

Kaitlin asked, "Look familiar?"

The girls cracked up and then quickly climbed the rest of the stairs.

* * * *

When I got to Z's bedroom, Z and Katharine were sitting on the bed side-by-side facing me. "Take off your socks and underwear," commanded Katharine.

As I stripped off my socks and underwear, I admired the beauty of Z and Katharine. Both were pretty and both had great bodies. Z's blond hair and light complexion contrasted with Katharine's dark brown hair and darker complexion. Katharine had an aura of dominance and pride - she knew she was beautiful, and everything was going according to her plans. Z looked meek in comparison but also content with what was happening.

Once I was naked, Katharine said, "Come here."

I walked over to in front of Katharine. She tilted her head up, and I leaned down and kissed her. She grabbed my hands and put them on her tits. I squeezed them, admiring their large size. Katharine kissed me slowly, letting me concentrate on her tits. They felt wonderful in my hands. How many times had I fantasized about doing this? How many hours had guys in my high school spent fantasizing about doing this? I gently explored them in a state of wonder.

After a few minutes, Katharine ended the kiss. She pushed me lightly toward Z. I stepped in front of her as she tilted her head up for a kiss. As I kissed her, I reached for her tits. They were already becoming familiar to me. I had a sense of ownership for them - Z was mine, and so were her tits. My feeling of love for Z swelled as we kissed and I groped.

When Z ended the kiss, Katharine slid even closer to her, practically touching Z. Katharine reached out her hands. I gave her mine. She grabbed my upper arms instead and pulled me toward her. She then reached up, grabbed my head, and guided it to her left nipple, which was the nipple on the far side of Z. Katharine ran her fingers through my hair as she had me suck on her tit. It felt magnificent in my mouth. After a half a minute, she moved me to her other tit. After I had sucked on Katharine's right tit for a while, she put her hands on me to move me toward Z. Z's hand then replaced Katharine's as she guided me to her left tit. I sucked on that tit for a while and then moved over to her right tit. It was amazing to have four gorgeous tits lined up for me to suck. As I sucked on Z's, I couldn't help wondering what would happen next.

When I had sucked on it as long as I had sucked on the others, Z's hands steered me back to Katharine. I did another pass, sucking on all four tits. And then a third pass. It was so awesome. I felt like I had died and gone to heaven.

"Let's get this party started," said Katharine as I finished sucking on Z's right tit for the third time. "Sit down on the bed, Eli." Katharine lay down on the bed on her side and moved back so that I could sit down in the middle of the side of the bed facing outward. Once I was seated, Katharine moved up to press her body against mine.

"Just like I told you to," said Katharine to Z.

Z dropped to her knees in front of me and then grabbed my cock. "I love your cock," she said as she kissed its head lovingly. She gave me a sexy look as she licked down the side of my shaft. "I love how it feels against my tongue," she said sultrily. She licked up the other side. "I love how big it is."

Katharine ran her hand across my shoulders. I turned a little and saw that she was watching Z intently.

Z opened her mouth and dropped it down on my cock. She then slowly pulled her head up, her tight lips making me shiver in delight. When she reached the top of my cock, she looked at me with her big, beautiful blue eyes and kept them locked on mine as she dove down on my cock again. She continued to keep her eyes on me as she slid her lips up and down my cock several times. She then let my cock pop out of her mouth.

"Such a yummy cock," said Z. She gave my shaft a big lick while looking at me. "I love the taste of it."

This was not how Z ever talked. "Katharine," I said like a question.

"I told her to be your little slut for one time," said Katharine. "Enjoy it."

"Okay." It was kind of fun.

I quickly switched my focus back to Z. Her lips were tight around my cock again as she pulled her head slowly up. She somehow managed to look up at me and give me a wink.

"That's it, Z," added Katharine. "Worship his cock, but do it slowly so he doesn't come."

Z put her mouth on the side of my cock and ran her lips up and down the length of my shaft while tickling it with her tongue.

"I do worship his cock," said Z sultrily. She seemed to be getting more and more into being my little slut. "I love how it feels inside of me. It makes me so happy."

Katherine snickered as Z took my cock deep into her mouth again. Z looked deep into my eyes and then slowly moved her mouth up and down my cock.

"She looks so beautiful," said Katharine. "And so happy." Katharine crooked her finger at Z. "Enough cock worshiping. Let's get you closer to getting fucked."

Z got off the floor and climbed onto the bed.

"Lie down on your back in the middle of the bed," said Katharine.

Z did as Katharine commanded.

Katharine said to me. "Get her off with your hand. I want to talk to you while you're doing that."

I kissed Z. "You okay with doing that?"

"Yes," Z said like that was a silly question.

I put my right hand on Z a little below her tits and started sliding it towards her crotch.

"I love how you touch me, Eli. It fills me with such excitement. I come so fast with you."

"Enough," said Katharine. "Focus on coming. I want to see you and Eli fuck."

I slid my fingers through Z's bush and then parted her pussy lips with my index finger. Z hissed. I made a quick circle around her clit and then ran my finger down the length of the right side of her pussy.

Katharine said to me, "Z has told you that I used to have sex parties with two other girls and three football players. After the first time I did, girls would come up to me and ask if they could be in the next party. Fucking a football starter was a big dream for these girls. But when we started having sex, these girls would say nothing about how excited they were about fulfilling their dreams. It used to make me so mad." Katharine said to Z, "This is your big dream, isn't it? For Eli to get you off and then fuck you."

Z smiled blissfully. "Yes."

My finger was back up to the top of Z's pussy, and I was making lazy circles around Z's clit. She had her eyes closed with a look of pleasure on her face.

Katharine turned back to me. "That's why I wanted Z this one time to be very explicit about telling you how much she enjoys sex with you. She really does love you tremendously and loves having sex with you." Katharine was lying out on the bed on the other side of Z from me. "When I first thought about bringing you and Z together, I confess that I did not have the best intentions. But now, I feel very proud about having contributed to my best friend being in a relationship that makes her so happy."

That made me feel very warm inside.

"If there's anything I can do to support you two, let me know. Be that getting you more privacy or covering for you."

"Thanks," I said. I really meant it. Katharine had always been so different, so much more flamboyant than everyone else that I never knew what I to think of her. Now, I realized how supportive of Z she was and how important that support was to the success so far of my and Z's relationship.

I turned my focus back to Z. I began working her clit in earnest, rubbing its right side a little harder. Z's eyes were closed, and her mouth was slightly parted. I rubbed my finger up and down the right side of Z's clit, gradually increasing the pressure. The look of pleasure on Z's face gradually increased. She suddenly said, "Yes! Yes!" and then she began shuddering. I stopped rubbing my finger. My sister spent several moments coming and then relaxed her body.

I kissed Z and asked, "Ready?"

Z grabbed my cock as I started to move between her legs. "I'm ready to have this wonderful cock inside of me again."

Katharine asked Z, "Are you excited about being fucked your big brother?"

"I'm excited about being made love to by the person who loves for the way I am."

Z spread her legs and guided my cock to her pussy. Once the head of my cock was inside of her, I pushed forward. I noticed that Katharine was lying on her back next to Z, her legs open and her hand at her pussy.

"This is so hot," said Katharine as she pleasured herself.

I returned my gaze to Z. I said, "I love you," as I continued working my cock deep into her.

"I love you, too."

"Kiss your sister," hissed Katharine.

I thrust forward, burying my cock all the way inside of Z. I then bent down and gave Z a slow, loving kiss.

When I straightened up, Z said, "Fuck me!" She turned her head to look at Katharine and then looked back at me. "Fuck me, big brother. Fuck your little sister."

Z's dirty talk excited me, and it seemed to excite her too. Later when Katharine wasn't here, I'd tell her how much I loved it, and, hopefully, she'd do it regularly from now on.

I pulled back and then started to fuck Z slowly. I glanced over at Katharine, and she was rubbing her pussy hard. Z's words seemed to have pushed her excitement to a new level.

I slowly picked up the pace. I was on my knees with my body mostly erect. I knew with all the stimulation from Z and Katharine's show and Z sucking my cock that I wouldn't last long, but I wanted to last as long as I could for Z. In this position, it was easy to keep things slow.

"Z, put your right foot on his shoulder," said Katharine.

Z did as instructed. Doing so resulted in Z rotating slightly to her left. Her other leg was bent around my right knee. I wrapped my hands around Z's thigh to help her leg up. I continued slowly fucking Z.

"Have you ever fucked in this position before?" Katharine asked Z.

"No."

"Good. Your big brother should be your first in as many ways as possible."

I smiled as I thrust into Z again. Z's eyes were slit now, and she didn't appear to be looking at anything in particular. I looked over at Katharine, and she was rubbing her pussy furiously while thrashing her head around.

I pushed Z's leg aside and moved over her into the missionary position. I increased the speed of my fucking her. I felt Z put her feet on my butt, and they started helping me thrust into her.

Z looked up at me and smiled. "Come in me. I love it when you come in me, big brother."

I had been close, and Z's words put me over the edge. I exploded, blasting a massive spurt of cum into Z. I looked over at Katharine. She was no longer pleasuring herself. She smiled at me as I continued coming in Z.

"Fill her up, Eli," Katharine said lazily. "Fill up your little sister with your cum."

I smiled at Katharine during my last few spurts.

When I was done coming, I bent down and kissed Z. "I love you."

"I love you, too."

I pulled out of Z and stood up on my knees. Z rolled to the side away from Katharine.

Katharine said, "Lie down on your back. Let me get you hard, and then you fuck me."

"Don't you want me to make you come?"

"I've already come. I'm ready to fuck. It was so hot watching you and Z."

I lay down on my back and put my head on a pillow. Katharine knelt next to my chest and then bent over to take my cock into her mouth. She started using her lips, tongue, and hand in amazing ways. She was far better than Z at giving head.

Z said, "Eli, it's my choice how you make love to Katharine. I want you to do it to her like you did it to me yesterday morning. I want you to make love to her, not fuck her. Say the same kind of things to her that you said to me. Understand?"

I thought over what Z said. I think I knew what she was hinting at, but I wouldn't know for sure until I started making love to Katharine. "I think so."

Katharine had me hard in no time. Z said to her, "Missionary."

As I moved aside so that Katharine could take my place, she said, "That'll be boring."

Z gave Katharine a knowing smile and then looked meaningfully at me. "Like yesterday morning."

Katharine began to spread her legs for me to move between them. Instead, I lay down next to her. "Katharine," I said warmly as I put my hand on her stomach. "You're so beautiful..."

"That's why you want to fuck me."

"And so amazing," I added, ignoring her interruption. I slid my hand up her side, avoiding her tits. "It makes me so happy to be with you."

Katharine frowned like she was unhappy with me for saying nice things to her.

I moved forward and kissed her gently. A long, soft kiss.

"Now are you ready to fuck me?" asked Katharine impatiently. I almost chuckled.

I stood up and started moving between Katharine's legs.

"I've been looking forward to this fuck all day," said Katharine. "I can't wait to feel your cock inside of me. I've been thinking about fucking you since I thought of getting you and Z together."

I was between Katharine's legs now and moving over her. She grabbed my cock.

"Fuck me hard. I love it when I'm fucked hard."

I continued moving upward. Katharine tried to guide my cock into her pussy, but I moved too high up for her to do that.

"Hey-" said Katharine.

I cut her off with a gentle kiss. And then another. When she tried to push her tongue into my mouth, I blocked it. I gave her two more gentle, romantic kisses.

When I pulled back, I gave Katharine my warmest smile. She looked - I don't know. Angry? Confused? It was like the hard shell she always kept around her was cracking.

"You're amazing, Katharine. You're beautiful too, but I want to make love to you because you're amazing."

For once, Katharine didn't seem to know what to say or do. She still had her hand around my cock, but she was gripping it lightly now. I moved down, and when my cock was back to close to Katharine's pussy, she sprang into action. She guided my cock into her pussy and said, "No more of this talking bullshit. Let's get down to fucking."

I thrust forward. Katharine put her feet on my butt and pushed me forward so that my cock was buried all the way inside of her. But instead of fucking Katharine, I leaned down, kissed her, and said, "This is a very special moment for me."

Katharine's eyes flashed angrily. "Dammit! This is a very special moment for me too."

I glanced at Z, and she was smiling at me. I looked back at Katharine, and her usual air of control was gone. When I had almost pulled out of her, I thrust forward slowly again. Katharine pressed her feet hard on my butt to make me thrust harder, but I resisted them.

When I was all the way inside of Katharine again, I said, "You look so beautiful lying there."

"Thanks," she said in almost an embarrassed tone before giving me a little smile.

I made love to Katharine slowly. She stopped trying to make me go faster with her feet. Instead, she slid them down to behind my thighs and gently caressed me with them as I made love to her. As I did, her face relaxed. She began lovingly moving her hands up my arms and across her chest. Every three or four strokes, I'd tell her that she was amazing or special or beautiful. Each time, she smiled, and each smile was bigger than the time before.

I bent down and kissed Katharine. This time, she kissed me back tenderly and lovingly. I resumed making love to her, picking up the pace. She moved her feet a little further up my thighs. She had accepted that I was going to set the pace of our fucking.

We fucked for a good while. I steadily picked up the pace. When I felt I was close, I said, "I'm almost there. Come with me, Katharine." She closed her eyes in concentration and slightly parted her mouth. I slowed my pace again as I got in my last few strokes. Third stroke, fourth stroke, fifth stroke.

I saw Katharine start to shudder as I began the next stroke. I pushed all the way and came, releasing spurt after spurt inside of her. It felt wonderful. It had been a great fuck.

I lowered myself until my lips were almost touching Katharine's. "You're amazing, and I'll always remember this."

We kissed a tender, loving kiss. When it ended, Katharine said in a quiet, soft voice, "I'll always remember this too."

I straightened my arms, pulled out of Katharine, and then rolled over to Z. She had been on her side watching us, and I rolled so that my back was now against her front. I twisted my head and kissed Z. "Thanks for letting me do that."
"And now you're back to being mine."

"I was always yours. You just lent me to Katharine for a while."

Z smiled and kissed me again. She then said to Katharine, "Did you enjoy that?"

Katharine gave a little sigh. "I enjoyed that a lot."

"It's great making love with someone who thinks you're special." Z squeezed me.

Katharine asked timidly, "Could we..."

"Could we do this again?" said Z, finishing Katharine's question.

Katharine nodded.

I knew that was between the two friends. I was fine with Z being the only person I ever made love to again, but I wouldn't mind making love to Katharine again.

"At Christmas time," said Z. "And on one condition."

"What's that?" asked Katharine.

"You have at least a three point five GPA for the semester."

Katharine looked confused. "Why?"

"So you can transfer to my college and be my roommate next fall."

Katharine burst out laughing. "And so, the student teaches the master."
