Changing Room Wank

I went to a large English boarding school, in the south of England. Understandably, the changing rooms were testosterone fuelled madhouses, especially during the younger years. There was one particular boy, Sam, who I'd always been a bit attracted to, and he often got a hard-on in the showers, which often set me off. Sam was small and quite a late developer, but with a cute face and a little bit of puppy fat.

One day before football, we were the last two left in the changing rooms, and I deliberately lingered with not much on, whilst casually fiddling with my penis in a typically pre-pubescent manner. Sam kept looking at me, keeping his towel draped suspiciously over his front. I Made some nervous reference to wanking, to break the obvious tension, saying I could do with one. He dropped his towel to reveal a significant bulge in his pants, then said something along the lines of 'I could do with one too.'

Nervously, I pulled the front of my shorts down and started fiddling with my stiff little member, which he just looked at, eyes wide. Slowly, he came round, and pulled his boxers clean off, standing in the middle of the changing rooms with a boner-albeit a small one, at only about four inches. We moved into the toilet area and stood by the urinals, him moaning fakely and me pumping away, transfixed by his disproportionately large balls. After barely a minute, I shot a load into the urinal, which he was amazed by, as he had apparently never come before. We had a number of experiences after that.
