One

I met Jenny when we were freshmen in high school. We were both fifteen. I had just moved into the city, so didn't know anyone. We both lived close to the high school, and ended up walking in the same direction for a while, and she was in a couple of my classes. We became friends quickly.

I was attracted to her almost at once, but was nervous about trying anything more than friendship. Jenny was beautiful, long blond hair, sparking blue eyes, and a body to die for. She had little dimples in her cheeks when she smiled. I was smitten.

However, it took me until after the first of the year to ask her out. It was late January, and I asked her to go to a movie with me that Friday night. "I was wondering what you've been waiting for," she said with a laugh, as she agreed to go.

We had a great time. I held her hand walking to the movie theater, and she snuggled up to me as we watched the film. We went for a burger afterwards. It was wonderful. The only weird thing was that she wouldn't let me walk her all the way home. She said, "You can't come to my house until I know you better." That made me a bit curious. However, she wrapped her arms around me and gave me a huge kiss after she said it, so I didn't care much.

This went on for a little over a month. We went out every weekend, seeing a movie, or going to a dance at school, or something. We went to the mall a couple times. Every time ended with her making me stop a couple blocks from her house, and wrapping me up in a hug and a big kiss.

March fifth was my sixteenth birthday, which was on a Saturday. I had a party planned, and Jenny was going to be there, but we went out, just the two of us, that Friday night. After the movie, she told me to walk her home.

"OK, I want to take you to my house. I have to know that I have your trust, though."

"You know I do," I told her.

"I have my parents' approval to bring you home, because they want to meet you. Plus, I like you, a whole lot, so you have to know what you're getting in to."

"What... ?"

"Don't say anything. Listen to me. I need your promise. You're going to see things at my house that you will find very strange. If you can't deal with that, I understand—that's why I wanted to find out now, before I really fell for you. But you have to promise me not to tell a single soul what you see."

"I promise."

She stopped, and looked at me. "I mean it. This is important. Lots of people could get into lots of trouble if this gets out."

"OK. I promise, Jenny."

"Good. This is my house." She walked to the front door, and led me in.

I walked in the front foyer, not noticing anything unusual. Then Jenny led me into the living room. I couldn't help but stare.

There was a woman on the couch, stark naked. Her legs were spread—and there was a guy with his face buried in between them! She was moaning, and thrashing around. She had heard the door close, so she opened her eyes.

"Hello, dear! Tommy, stop for a second." The guy between her legs pulled out, and I recognized Tommy Pelham. He was a guy from school, one that I didn't particularly like, but he was my age! And this woman looked old enough to be...

"David, this is my mother," Jenny said.

"Hi, David! Nice to finally meet you after hearing about you for three months!"

"Uh, nice to meet you too, Mrs. Keltner."

She laughed. She had a very pleasant laugh. "Jenny didn't warn you, did she?"

"Not about anything specific, no."

"I thought so. You blush wonderfully." That made me blush more. "Don't worry about it. Jenny will explain. Enjoy yourself." And she pulled Tommy back between her legs.

"C'mon," Jenny said, taking my hand. She led me to the kitchen. There we found a man, naked, standing behind a woman, naked, who was bent over the kitchen table.

"Dad, hold up a minute!" The man stopped his movement towards the woman. "This is David," Jenny said.

"Nice to meet you." He just waved. "He's sworn to secrecy?" he asked Jenny.

"Yes," Jenny said.

"People could go to jail if this gets out, David. We've had outsiders before, but we have to be cautious. Jenny likes you a lot, though, so her mother and I consented to let you know what her family life was like. This is all consensual. Jenny will explain more, I'm sure. But this is a closely guarded secret." His voice was kind but stern, which was rather incongruous coming from a stark-naked man with an equally stark-naked woman bent over waiting for him. I understood, though, that this could never get out.

"I understand, sir. I need Jenny to tell me more about this, but I don't want to hurt her, ever, for any reason."

He smiled. "Good. Enjoy yourself." And, with that, he gripped his cock and started to enter the woman.

Jenny smiled at me, then took my hand and led me out of the kitchen. She went to the staircase, and led me up. We walked past a bedroom, with the door open, and heard moaning inside. Jenny peeked in, then motioned me. I saw an older guy and a girl younger than Jenny going at it. The girl was on her back, spread eagled, as the guy pumped in and out of her.

"That's my older brother Eric. He's 22. And that's my little sister Melissa. She's 14."

Brothers and sisters? 14 year olds getting laid? What had I stumbled into?

Jenny grabbed my hand again, and led me into the next bedroom. "This is mine." She sat on the bed, and motioned for me to sit on it, too. "So, how shocked are you?" she asked me with a twinkle in her eye.

"Uh, very."

"It's us and the Pelhams. They live next door, you know. Our families all have sex together, and with each other. You just saw my brother Eric, right? He took my virginity when I was 11."

"My God."

"Yeah, most of the world thinks it's wrong, or sick. For us, it's normal. I've had sex with every male member of my family, and of the Pelhams." She giggled. "And some of the female ones, too. It's all voluntary. When we're thirteen, we have to sign The Agreement, but there's ways to get out of that, and exceptions to it, too. My sister Vicki, she's twenty, she got out of it for three years."

"The Agreement?" I asked.

"It's sort of a contract. It governs our behavior in the two family unit. For instance, only in certain instances can I turn down sex, with any member of the two families."

"You have to have sex?"

"Well, some of the instances are pretty broad. My room is my own space. You have to be invited in here. If I'm in here, I'm not 'fair game.'" She giggled. "Of course, getting here is sometimes an adventure."

"But, what if there's one person, or a couple, that you just don't want to go to bed with?"

Her eyes got a little clouded over at that. "I'm not allowed to do that. We're a collective."

"Oh." I was overwhelmed. "What about sex with people outside of the Agreement?"

"Allowed. Encouraged. Given wide berth when it comes to the Agreement—nobody was allowed to approach me today, because I was bringing an outsider in. It has to be done here, though. I have complete privacy in this room, but, I couldn't, like, go to your house. It has to be done in this house, or in the Pelham's, but I don't have my own room over there."

Light suddenly dawned. "You mean ... you brought me here because..."

She giggled. "Yes, I brought you here because I want you to fuck me silly."

Three

This was completely unexpected. I had never even done more than kiss her. And now she wanted me to ... to...

I was a virgin.

"You're blushing!" She noticed. "You're not a virgin, are you?"

"No." I lied. I didn't feel like admitting it to someone that had lost her virginity at eleven. But I hedged it, because she could tell I was nervous. "I'm not that experienced, though."

"That's OK." She leaned over to me and kissed me. "I don't mind." She kissed me again, while rubbing her hands up and down my chest. "I've been told that, well, I'm rather easy to satisfy." She giggled.

I sat for a minute, to clear my mind. Not only was I a virgin, I was completely inexperienced. When I took off her shirt, that would be the first time I ever saw ... well, you know. I had to think. I had been prepared for this, I needed to remember my lessons. If I did, she'd probably not guess just how inexperienced I really was.

Y'see, my parents are kind of weird. Dad, especially. The sex education I got at home, most kids would have begged for. I didn't just get the mechanics, plus all the warnings about diseases and pregnancy. My Dad made sure I learned what sex was really like. I got instructional videos and everything. Dad told me that, his first couple of times, he didn't know how to please a woman and that, because of that, they were disasters. He had to figure out how to please a woman by himself. He didn't want that to happen to me. He thought it was important. "If you decide you're going to have sex, do it right," he said. It was very tolerant and open—especially considering my younger sister, who was 12, was starting to get the same kind of thing—but, like I said, a bit weird.

Of course, I was sitting here with a girl who had been to bed with every member of two families, one of them her own, so who was I to judge weird?

And she was waiting for me. I reached over, and started pulling on the bottom of her shirt. She helped me. I got the bra off, myself.

She took my breath away. Her tits were ... perfect.

I touched them. I gripped one with one hand, while I played with the nipple on the other one with the other hand, desperately trying to remember those instructional videos. It seemed to be working, because she was all red, and gasping.

After a while of this, she reached out for my shirt. I disengaged so she could slip it off. And then she went for my pants. I helped her get them off. How I even had the wherewithal to do that I couldn't tell you. The next thing I knew, her hand was on my dick.

Oh my God.

"Oooh, very nice," she giggled, as she ran her hand up and down it. Boy, did it feel a lot better than my hand. And if she kept it up, she was going to find out just how inexperienced I was. Cumming in thirty seconds from your very first handjob tends to give that away.

I needed something to occupy myself, and in a hurry. That was easy, once I thought about it—her pants were still on.

"Hold up a minute," I said, as calmly as I was able. Your turn." I reached for the snap of her pants. She smiled, and raised her ass so I could slip her jeans and panties over it. She kicked them off, and there she was, stark naked, smiling at me.

Oh, she was heavenly.

Instructional videos, remember, dummy, I said to myself. I moved my hand down between her legs—she obligingly spread them for me. She was sitting facing me. I reached down and rubbed my hand up and down her pussy. Boy, was she wet. I guess I excited her. That was a nice thought. I probed where I thought her opening should be, and I found it, right off. The videos were proving to be a big help. I slipped my finger in her, and started moving it back and forth. "Oh, David, yes..." she whispered. I took my other hand and went for her clit, hoping I'd know it when I found it. Her stiffening and barking "OH!" when I found a little nub let me know I had hit paydirt.

I rubbed her clit while I slipped my finger in and out of her. "Oh David, Oh David, oh David!" she cried, and then she went all stiff, and I felt her pussy clenching on my finger. Her face was all red, her eyes were closed, and her mouth was wide open, with low moans coming out of it. I stopped my hands and watched her regain her breath.

"Wow!" she said. "That was great! You're really good at that." Wow, I thought. My first time, and I was being told I was great by a girl who definitely had a basis of comparison.

I just looked at her, as she smiled at me, and then I decided there was something I wanted to try. I pushed her down, so she was lying on the bed. She looked at me questioningly. I just smiled at her, then crawled down between her legs. Now that I had figured out where her clit was, I went right for it with my tongue.

"OH DAVID!" she yelled, and immediately started gasping. "WOW! WOW! WOW!" It seemed like she was really enjoying this. She wrapped her legs around my head and yanked me in closer. "YES! YES! YES! YES! OH DAVID YESSSSSSSSSSSS!!!" she screamed, and then she went stiff again.

"Jesus Christ, that was fantastic!" she said.

"Thanks," I said, pleased.

"My turn!" She reached over and engulfed my prick in her mouth.

"OH JESUS!" I yelled. Not to my surprise, I didn't last long—I didn't even have a chance to warn her, before I started spurting into her mouth. She didn't seem to mind, and swallowed every drop.

"Sorry," I said.

"For what? I don't mind drinking cum. In fact, I kind of like it. I didn't expect it quite so soon, though," she giggled.

"Well, that was my first time for that. Lots of girls won't do that, even if they'll do other things," I said, not exactly lying.

"True." She looked down in between my legs. "Look at that! You're still hard! Oh, goody!" She lay back down on the bed, and spread her legs. "Don't worry, David. With all the sex that goes on around here, we get checked out regularly, and I'm on the pill. I'm as safe as can be. Fuck me now, please?"

So I did. I climbed on top of her, grabbed my cock, and aimed it at her pussy. I drove it into her. It felt fantastic. "OH YES!" she yelled, as I started moving back and forth inside her.

How I didn't cum in her in twenty seconds is completely beyond me—the blowjob must have made it less urgent, or something—but I managed to fuck her for a lot longer than I would have expected. It was stupendous. She wrapped her legs around my hips and grabbed my waist as she thrust up at me every time I pushed into her. She was groaning and gasping, shouting stuff like "OH YEAH! FUCK ME! OH GOD FUCK ME!" the whole time. I lasted long enough for her to cum again—and the feeling of her orgasming pussy clamping down on my cock was all I needed,

"David, you are wonderful," she breathed up at me after we were done. "Your previous girlfriends were very lucky—how on earth they didn't hold on to you is beyond me." I didn't say anything, just blushed at her.

Four

She came to my party the next day, and then, afterwards, we slipped back to her house and went at it again. A couple of afternoons the next week, and then that Saturday night, found me up in her room fucking her silly.

I was in heaven. I already knew I liked this girl, a lot, before we ever had sex—but the sex just made it better. At that point, I even liked the whole Agreement thing—it certainly had made her enthusiastic and appreciative in bed. What she did when I wasn't there didn't concern me so much at that point.

That started to change the following week—but, at first, I didn't mind that either, because there were other benefits. I went over to her house that Tuesday afternoon; but, before we made it to her room, we were confronted by Tommy Pelham. He grabbed Jenny. "Come on, you know the rules."

Jenny looked at me and said, "I'm sorry, Dave, they are the rules. I have to go with him. I'd like you to wait, if you're willing. Oh, and if anyone approaches you, you don't have to go with them, but you're free to, if you want."

I was shocked at that. "You mean if someone else here wants me to have sex..."

"You can, if you want. In fact, I think my little sister Melissa is very interested. I told her how good you were." She giggled, and followed Tommy into a room somewhere.

"She's right," I heard from behind me. It was Melissa. "She told me you knew your way around a girl better than anyone in this house. I'd like to see, if you want."

Jesus, what have I stumbled into? I thought, for not the first time. Here was my girlfriend, going off to have sex with another guy, but her fourteen-year-old sister was proposing I have sex with her.
