This is actually a true story about the first time I had sex with another guy. I had been friends with a guy named Sean who lived across the street from me. He was a couple months older than me so he was already eighteen by the time my birthday came around in August.
I had fantasized about having sex with guys but I never fantasized about him until the night after my eighteenth birthday when we were outside jumping on a neighbor's trampoline. During the day, there were always tons of kids playing on and around the trampoline, but it was late and most of them were heading off to bed. Since it was just the two of us, and the trampoline was placed at the end of the our neighbor's open back yard, we actually had a lot of privacy. So when I told Sean I had to take a piss, he said he did too and we should just do it outside. We jumped off the tramp and I quickly began relieving myself. I didn't look at him, partly because I didn't feel attracted to him at the time, but partly out of shyness too. But he obviously wasn't as shy.
"Wow, you're bigger than I thought!" he exclaimed when I unzipped.
"Yeah, bigger than you!" I joked and we laughed together.
We finished taking a piss and jumped back on the tramp. I didn't think anything more about his comment, and we talked about school starting soon and other things when he asked me a question that started me thinking.
"Hey, do you want to go over to my house? I just found one of my brother's porn tapes and I want to check it out."
"Sure, I'm game," I replied. I had never seen a porn movie before, but I had several men's magazines stashed away, one of them being a Penthouse. I loved the letters in that magazine, and one in particular actually got me to start fantasizing about guys. It was about two female friends who get turned on watching each other undress and coupled with the lesbian pictorial in the magazine, it turned me on more than anything I had ever read or imagined before. Then one day, I thought of putting myself into the story, and naturally my "friend" in the story would have to be a guy. So I imagined doing some of the same things with my friend that the two women had done together, undressing in front of each other, getting turned on, then coming by rubbing against each other.
