This thread reminded me of a memory I had not thought of in a while. When I was a young man, I was excused off a gym session --I forget why-- and I got tired of watching the class, so I went into the empty locker room with nothing in mind but pure wondering boredom... once I got there, realizing how still everything was, I went to the gang shower and pumped up a young man's pent up load. It was hot realizing I had been there with my mates so many times, and that potentially I could be caught. Good time
Aside, I do often jerk off at the gym showers (cubes), and yes I do clean up. Its just such a great way to relax and end up a hard workout.
Twice --both time with the same young man, who I don't know--, I have jerked off across the corridor: he's always started it, leaving his curtain about a foot open, jerking off, eyeing me, and I've returned the favor. At least one time guys going to shower cubes further down the hall must have seen us jerking - no evident rection but who knows what they did in their shower stall out of my sight
