This happened when I was 14, now I am in my late twenties. Me and my friend Dave were sleeping over at Tommy's house. They were also 14. After some late night TV we decided to go to bed. After some chatting about girls, Tommy delcared that he had a major hardon and needed to do something about it.
Me and Dave played dumb as if we didn't understand. In seconds Tommy stands up and drops his grey boxer-briefs to reveal a cock that made our mouth's drop. This guy had an uncut cock that was at least 7.5 inches long and 6 inches thick. He started right away and pulled the foreskin back to reveal a mushroom head covered with precum. In seconds, me and Dave followed. Dave showed his cock and started jerking. He was about 6 inches and uncut which was a little smaller that my 6.5 inch uncut cock.
Over the next ten minutes we jerked and pulled and played with our dicks and balls, until a wave a orgasms hit the room. Dave was first and shot his load on his tummy and chest. Next was Tommy. He pumped his massive foreskin like nothing else and unloaded white jism all over the two of us, which set me off and I came all over my chest. After we cleaned up we agreed that it was fun and dedicated ourselves to a regular circle jerk.
