Dawn was my favorite cousin and had been since we were little kids growing up in Maryland. We just clicked, always did. If she was around, even a dull weekend get together with our relatives was fun. She was a tomboy and liked to do things outside so we would ride ponies in granddad's pasture and climb trees, look for frogs and all those fun things you did in the country place we grew up in. I was so comfortable with her that I pretty much forgot that she was a girl.
We ended up going to separate high schools and then off to college and didn't see much of each other for a few years except at Christmas time. She spent her summers in a beach town in Maryland where she waited tables, and I spent mine working in New England where I went to school. One summer I decided to work in my dad's campground business at home and to my delight Dawn had decided to stick around to take some courses at a nearby junior college. So, we started to hang out together. She took tennis lessons in the early morning so I would meet her over lunchtimes or after work to play tennis and then go party in town. It was so much fun because it was so non-threatening to be with her, I could be myself and talk about other girls and she would talk about problems with her out of town boyfriend. It was all so easy and maybe that's why I enjoyed it so much...and there was something there sometimes, I could feel it. Maybe it was our common observations about people, our fondness for sick jokes, I don't know, but every once in awhile I would look at her and wonder what it would be like to like to be sexually involved. At first, when I had these thoughts, I would quickly try to think about something else. It was strange to think that I was imagining sex with my cousin; after all it was like she was my sister. I couldn't help but wonder if she saw me look at her that way and if she had those thoughts about me, too.
One of the events of the summer was my brother's wedding in his fiancΓ©'s hometown in Pennsylvania. Since so many friends and relatives of ours were going, a bunch of us decided to rent a house close by for the fun and convenience of it. After the wedding, there was a huge party and we were all very hammered by the time the bride and groom took off and everyone else wandered away. Somehow the very drunken crowd all ended up at the house and since we were still wired from the party, someone suggested we go night swimming in the pool. Nobody bothered grabbing their swimming suits, we all just grabbed beers and went. One of the nimbler partiers in the group climbed the fence and unlocked the gate from the inside. Soon, everyone was down to their underwear or less and swimming in the pool. Dawn was modest and a little reluctant to undress all the way, as was I. So, out of the corner of my eye, I watched her strip to her underwear and dive in. She had a tight little body for her 5'1 frame, firm breasts and athletic legs.
I had only seen her in tennis shorts before so this was a new and, uh, very enjoyable visual for me. I got down to my boxers and went in after her. We had a great time splashing around in the pool, throwing each other in and pushing people off the board. I found myself looking at her wonderful body as we played and trying not to get a hard-on. Dawn's bra could not hide the top of her aureoles or her long nipples that stuck out, excited by the cold water of the pool. Her thin panties defined the lips of her labia and the dark brown hair of her pubic mound. I couldn't keep my eyes off her as we laughed and enjoyed a beer by the poolside. Even with a buzz on I could tell she knew I was looking at her...and she liked it. Soon, it got too cold and we all went back to the house
Since it was all a big party house with too few bedrooms, the couples got the bedrooms and rest of us had to be content with folding couches, blow up mattresses and sleeping bags on the floor. Dawn had changed now and was wearing a T-shirt and panties for bed. She came over and put her sleeping bag on a huge queen size fold out couch in the main party room. A few other people scattered their bags in other parts of the room and I put my sleeping bag on the floor beside. As she unfolded her sleeping bag, she said the floor looked uncomfortable and I could share the big bed with her as long as I remembered to stay on my side. She laughed as she said this but her voice sounded inviting and sexual, something I hadn't felt until tonight. I tried to be non-chalant but the truth was that I was highly aroused by her smell, the feel of her skin, her soft hair and the fact that I had a crush on her. I sensed Dawn was aroused, too, and was trying just as hard to hide it. She said it was cold and so why not spread our sleeping bags out top and bottom like blankets? I agreed and undid mine and we put them down. Then we got in on opposite sides of the foldout sofa
