Mutual Sex Education

Our two families were friends from before I was born. Our Dads were buddies from the time they were kids and their wives seemed to get along great. Each family had three kids. I was the oldest in mine so we were boy, girl, boy. DiDi was the oldest in hers, which went girl, boy, girl. DiDi, real name Diane, was three weeks older than me. From what I’ve heard, we often shared a crib together as infants and were always paired off as the two families got together. And we got together a lot. We even took summer vacations together. I guess our younger siblings paired off, too; each time boy-girl. But I never paid much attention to them except when DiDi and I were forced to baby sit them.

I was always bigger and stronger, DiDi was always smarter — well, that’s not right, we both did well at school. As I think about it, I guess she was more of the leader, the one that came up with ideas.

Anyway, this year we’re both eighteen, both have graduated from high school. Our families are going back to the same place we’ve been to for several years. Except last year. I’m not sure why but we didn’t vacation together last year. In fact I haven’t seen DiDi for more than a year. We’re spending a month at this farm house. Used to be a real farm house. Now it’s rented out to people like us, I guess. It has a small lake, or big pond, right there. Good for swimming. It also has an old barn, although it’s not used for much now. Perhaps as a garage sometimes. The three boys get one bedroom, the three girls another one and the parents each get a bedroom. The girls have a bathroom, the boys have one and each of the parents bedrooms has one. It has a big porch and I remember our mothers sitting out there a lot, relaxing and talking, rid of us kids, who are most likely swimming or hiking through the scraggly woods. Our Dads commute from town for two weeks then spend two weeks with us.

So, this year, my family gets there first. We’re all unpacked and sorted out by the time the other family arrives. My Mom calls me to help unpack the others. I’m in my bathing suit. I have to admit, I’m showing off a little. I’m built. I’ve played football and basketball and I’m in good shape. I’ve grown the last couple years and am now six foot one. The last time we were all together, I was probably four or five inches shorter and 30 pounds lighter. So I go outside, off the front porch to their car.

DiDi gets out. She’s wearing shorts — short, tight, shorts — and a halter top. She’s grown a lot, too. She could be a Playboy centerfold. Really built. Real breasts. I mean, noticeable breasts. Great legs. Solid, round butt. And cuter than ever. I started to get a hard on just looking at her.

“Hi, Mike,” she says, smiling and moving fast towards me.

“DiDi,” I say, “Wow, you’re gorgeous!”

She smiles even more and comes to me and puts her hand on my stomach and sort of rubs it and then slides it up onto my chest. “You’re pretty gorgeous yourself,” she says, “You must work out.”

I don’t know what to do. I’ve got a full boner and it shows when you’re just in a bathing suit — boxer type suit. “I’m really glad to see you,”I say. Then quickly, “I better help carry in your luggage.” Truth is, I needed to hold something in front of me to hide this hard-on. I managed to get a couple bags with DiDi sort of following me, still touching me, almost rubbing my bare chest and then my back.

“I’ve been looking forward to seeing you again, Mike,” she says. “It’s been a while.”

As I hide my embarrassment with a suitcase, we talk and agree that as soon as she changes, we’ll meet down at the lake. Meanwhile, our Moms and Dads are all talking to one another and our brothers and sisters are all talking to one another. DiDi follows me into the house as I carry the bags upstairs and put them in the right rooms. She grinning real big and I’m pretty sure she’s seen my boner. I just can’t manage to hide it.

“See you in a minute down at the lake,” she says as she starts into her room. She reaches behind her to untie her halter top and I’m almost positive I manage to get a glimpse of the side of a bare breast as she went into the room. If it was possible, my boner got bigger and harder.

I got a big beach towel and held it in front of me as I went down to the beach. Well, it’s not a beach. It’s a clear dirt area that’s on the edge of the little lake. There’s a float about 50 yards out. I lay down my towel and go into the water deep enough to hide my erection. In no time the four younger kids come running down noisily, paired as DiDi and I are, boy and girl. One pair is now 16, one 14. I thought to myself that this is close to the last year they can be buddies like DiDi and I always were. But I know that we can never be the same again. I don’t know what’s going to happen but it isn’t going to be like it used to be.

Then here she comes, running. She has on the briefest bathing suit the law must allow and is almost popping out of it all over. Her breasts are bouncing. The bottom is moving with every step and I’m sure I’m seeing some pubic hair with each movement. God, she’s the most gorgeous female I’ve ever seen. We both have dark hair and brown eyes but her skin is close to white; often pink as she gets excited or worked up. I’m slightly darker. Not really dark at all but just not as white as her. She drops her towel and continues to run right into the water, right at me. She starts taking high steps, leaping slightly through the shallow water, and when she gets a few feet away she leaps onto me, knocking me over.

We’ve always played in the water, pushing each other under, almost wrestling. So, I roll under her and reach around and grab her. She twists and has hold of my bathing suit. Then I realize two things. One, she’s about to pull my bathing suit off and, two, I have one hand holding onto one of her full, lovely breasts. I let go and grab my suit to make sure it stays on. She laughs and pushes in deeper and starts to swim to the float. I catch up just as she gets there. We’re in the water, facing one another, holding on to the float with one hand. She looks at me and laughs lightly and puts one hand on my waist.

“I almost had you,” she says, smiling.

“Yeah, well I would have had you except you were pulling my bathing suit off,” I reply.

“Well, I haven’t seen you naked for a couple years,” she replies, grinning even bigger.

I look at her for a moment and swallow, trying to get up nerve. “DiDi, you’ve always been my buddy, my best friend. My best girl friend, anyway. But I think it’s all changed. We’re too grown up. You’re a very sexy girl now.”

“Well, I’m glad you think so but so what? ”

“Well, uh, ” I stumbled, looking at her and trying to think what to say. “Do you ever think of sex? ”

“Yeah,” she says, still grinning.

“I mean male-female sex, sex between people.”

“Well, yeah. A lot.”

“Me, too. Almost all the time. I watch things on the Internet.”

“Me too. I’ve seen guys and girls doing just about everything they can with each other and I read stories about it, too.”

“Well, doesn’t it make you sort of, uh, want to do stuff like that yourself?”

“Certainly. Yeah.”

“Well, have you? I mean have you, uh, fucked a guy?”

“No but I sure want to. How about you? Have you ever done it with a girl?”

“No. I don’t know why. I want to but I think maybe I’m scared a little. I mean, I don’t know what to do and I don’t want to mess up.”

“Yeah, me too. It would be embarrassing.”

“But see, that’s what’s wrong now. I can’t just be a buddy I don’t think. When I look at you I think of sex. I mean, I’d rather be naked with you somewhere, in a bed or up in the hay loft maybe, than down here just being a buddy.”

She looks at me a moment and I wonder if I had just lost a friend. We’d known each other our whole lives and I thought I could say almost anything to her but maybe I went too far this time. “Yeah,” she says, still grinning. “We can learn from each other. The hay loft sounds about right. Bring your towel,” she adds as she turns and starts swimming to the shore.

She scoops up her towel and runs towards the barn. After a delay caused by shock, I go after her, get my towel and run, too. The hay loft doesn’t have any hay. The barn hasn’t been part of a real farm for years. It’s just a partial second story, a bare floor. I climb the ladder built into the barn and watch her solid, round butt move as she climbs ahead of me. She looks around and goes over to one side and puts her towel down, spread out. I put mine next to hers. We look at one another and she steps to me, puts her arms around me and the next thing we’re holding each other and kissing. I’d never kissed a girl exactly like this. Her lips move some and then her tongue shoves itself into my mouth. So I do the same to her. It’s almost like sex already, just kissing.

“Mike, you’re really good,” she said as she steps back, keeping both arms on my waist. “Well, she then says, looking me directly, “I guess we might as well get naked, huh?” She reaches behind her and unfastens her bra and those beautiful, pink, full breasts almost explode out, free and loose. Big, dark red, sort of maroon, nipples are staring at me. I think I just stared back. “You too, Mike.” She then starts pulling her bathing suit bottom down, bending over and stepping out of it. I quickly do the same and my huge boner jumps out, stiff and straight. ”

“I’ve never seen a guy naked before,” she says. “Never seen a real live penis. Can I touch it?”

“Uh, sure DiDi, whatever you want.” She steps close to me again and puts her hand on the side of my cock and sort of strokes it a little, then wraps her fingers around it.

She’s looking at it and then looks me in the face as she holds it. “Wow,” she says. “It’s pretty big, isn’t it. And sort of alive or something.” Then she backs up some and sort of pulls me by my cock towards the towels. She lets go and lays down on her towel so I lay on mine, facing her and we’re hugging each other and kissing again. I feel her breasts against me. I run my h ands down her back onto her butt. Boy, it feels great. Solid but with some give to it. I can feel my cock pushing into her abdomen. She ‘s doing the same to me, feeling my butt and licking the inside of my mouth. Her whole bottom starts squirming against me. I think she’s rubbing her body against my cock.
