True story that took place at my old gym, I've left there now as the prices have risen and I can't justify the expense any more.

After working out I always like to go for a dip in the jacuzzi, heading back to the locker room I stripped off and went for a shower. I'm one of those guys that shrinks after a workout so my admittedly small penis was barely more than an acorn. I was naked this time, sometimes if it's busy I wrap a towel around but if it's quiet I try not to get the towel sweaty.

I stepped into the shower cubicle and hung my towel over the door, noticing a guy was next to me in the adjacent stall. With the frosted glass all you can see normally is a pinkish blur, especially in the area where I live, but this was a black guy and his dark skin stood out against the pale marble. No big deal but when he turned sideways I could see his erection through the glass, I'm sure this happens all the time and I sometimes get a boner but it's not noticable.

I felt self-conscious but couldn't stop staring, it was big, not huge like a porn star but very much larger than mine, I could feel myself getting aroused. I don't think he knew I could see him but he started to stroke it, it must have been a few minutes while I held my breath before he stopped and left the shower.

I had to wait for my erection to disappear before I left the shower, I looked out for him but didn't see him again, anyway, true story, wish it had progressed but I doubt he'd be interested in a small dick cuck like me.
