It was GYM day at the school I go to...(All boys High School) Normally we would have to bring our Gym clothes in another bag and change in the locker rooms. I try to change quickly because my penis gets a hard-on rather quick once I'm in underwear or naked. I was the last one in the locker room because I had to talk to the coach real quick.
When I pulled down my gym shorts I had a raging hard on and it was really noticeable. When I went to reach for my pants in the locker someone said 'Want help with that down there'. When I turned around it was a kid from my class.
He reached for my hard on and brought me to the showers. He rubbed my cock a bit and then went for my waist and said 'May I?'. I said sure and he slowly took of my Boxer-briefs revealing my hard 7' cock.
He started to beat it and it felt really good.
I came a huge load on his face and his chest. I helped him clean up and gave me a quick kiss and said 'I enjoyed it a lot and want more soon'
