This happened to me the other day. I couldn't believe it. I am seventeen years old, blonde hair, blue eyes, muscular and athletic.
I was playing hockey in the morning with a bunch of other guys from around, nothing too serious, just a quick game of shinny. The pace picked up and by the end I was drenched with sweat, like everyone else. The arena we were at was large, and we were the only ones there, except for one other guy. So we undressed and hit the showers. There were four in our room, right next to each other without curtains or anything.
So as I'm showering, I notice the guy next to me, who was 14, staring at my cock, which is about seven and a half inches and five round. It was semi erect because it always is when I'm naked in public. The two other guys also noticed that this guy was staring at me, they were 16 and 17. They started bugging him. Then they decide that since he likes looking so much that he should do us all a favour and jerk us off. He thought that sounded good. So he starts with the 16 year old, and me and the other guy start pumping ourselves. The other guys in the room start complaining that we are taking a while so we decide to finish up outside of the showers. The room was still fairly full, maybe six or so other guys, so we continued with our fun and they decided to join in. So the 10 of us are going at it, and in walks the manager to tell us our time was up.
He was 27 or so, very hot, not that I'm gay, I just noticed. At first he got kind of mad, but then someone told him to join in. Everyone stopped what they were doing and looked at him. He paused for a few seconds and then agreed, so he peeled of his shirt revealing his abs and then the 14 year old runs over, opens his jeans and rips down his pants. There he is, standing there with 10 naked guys at least 10 years younger with nothing but white briefs on. They were tight and revealed his huge bulge. I decided that they too needed to come off and pulled them down. We all messed around and half an hour later we decide to call it quits. That was the most exciting time I ever had in a locker room.
