I told him I would never want to jack-off with another guy.
One night when I was about 13, I slept over at my best friend Billy's house. We were talking about how many girls we were going to fuck when we got older and were starting to get ourselves very excited when he asked me if I had ever jacked off with another guy. I told him that I would never want to do that. He told me not to knock it if I had never tried it. He admitted to me that another older friend of his and he had jacked off once together. I asked him what it was like and he said 'It was really cool and asked me if I would like to try it?' I didn't think that I did, but noticed that my cock was getting very hard, and so I said that he could go ahead and jack off in front of me if he wanted to. He instantly pulled out his very hard cock and began to rub it in front of me. Before I knew what I was doing, I reached down and touched my own cock through my underpants and before long we were reaching for each others cocks in the dark.
His cock was much bigger and hairier than mine and it was already very hard. He had some oil under his bed and brought it out and put it on both of our penises. Soon he started rubbing mine up and down and I did the same to him. He started kissing my cheek and telling me how much he loved what I was doing to him and I did the same. I knew I was about to come and knew that I wouldn't be able to stop myself.
Before I knew it, I was coming all over his leg. I kept rubbing his cock as he also began to come on my leg too. It was the wildest thing I had ever experienced in my life and I decided that I had to try this again.
All of a sudden, his mother knocked on the door and told us to stop making so much noise and go to bed. We quickly pulled the covers up and told her that we would. We smiled at each other. I told him that I would have rather done that with a girl, but told him it had been great with him anyway. He agreed and soon we were both fast asleep.
We had many other nights together during our teens, but this was the first.
