I was thirteen at the time
When I was thirteen, I had a certain group of kids who I hung out with. There were four of us in total: Ryan, Joel, Jared, and myself. Jared and I were always the closest of the four of us because he lived right around the corner from me. Even when the others weren't about the two of us would hang out.
One time the four of us decided to play truth or dare. It started off as stupid things, like take off your shirt or your pants, or squeeze his nipple, but then we took it to the next level. I dared Jared to take off his pants and his boxers, and he did. Then it was his turn. Instead of going to someone else, he dared me to take off my pants and underwear. So now Ryan and Joel were fully clothed and Jared and I had no pants on.
After a few more rounds, Joel dared me to go underneath my fold out futon couch and to touch Jared's dick. We both went underneath it and I touched him. Then I dared him to jerk me off for ten seconds. Now, when your under my couch, you can't see outside and no one else can see you. So he started to jerk me off and after ten seconds he just kept going. I told him his ten seconds were up but he said he didn't mind. He kept going and on his next turn he dared me to jerk him off.
We sat under that couch and jerked each other off and kept playing the game with Ryan and Joel. Neither of them had any idea what was going on. His pale, throbbing cock felt amazing in my hand. I had never felt anything like the way his hand felt on me before. We were working in a rhythm together and his body started jerking all over. He sped up and I felt myself about to come. At almost the exact same moment we both came all over each other. Our semen lay there mixing on both of our chests and I rubbed it all over his lower stomach and pubic area. He did the same to me. The game ended and soon all three of them went home.
Since he lived right around the corner he came over by himself all the time, and we would play truth or dare just the two of us. This was our excuse to just sit around and jerk each other off.
The next week he invited me to sleep over at his house.
