There was a time in my undergrad, not that long ago, when I went to the lockerroom after a run. In order to get to the pool you had to walk past the shower stalls. For some reason, there were no curtains on most of the stalls. I admit sometimes I went to "check" the pool times, so I had to walk past the showers. Sometimes you'd get a glimpse of a hot jock that way, but usually just his bum because guys would tend to face toward the wall behind them in modesty.

But anyway, this one time I'm talking about, I was in the nearby bathroom washing my hands at the faucet when this really hot jock came out from the showers around the corner, buck naked and dripping wet and a little embarassed. It seems he had forgot his towel altogether, so he came in to get some paper towels to dry off with instead, of which he needed many. When he saw me there he laughed about it akwardly, "hey man, don't have a spare towel?" I really didn't.  I washed my hands much longer than needed. Using the mirror right there I could see every inch of him while he dried off with the paper towels, floppy cock and all. I went to the airdryers behind so that I could see his ass while he was bending to dry his calves, which is just such a great angle. It was one of those bums that has just the right line of hair running up the crack. He probably did not realize how much he was being enjoyed.
