When I was in basic training for the Army in 2000, I generally liked to wait until after "lights out" to shower for the simple fact our drill sergeant went home (unlike most others). This afforded me the chance to take my time and enjoy the hot water (at 21 I was older than most of the other guys and needed the recuperation from sore muscles). On very rare occasions, this also afforded me the chance to rub one out as well. Our shower bay had 4 heads along each wall, each one separated by a wall about 4 feet high, with no curtain. Well eventually some of the younger guys "caught on" to why my "old ass" waited until late to shower, so it wasn't uncommon for other guys to come in. One night toward the end of basic, I knew it was going to be one of the times I jerked off, so I waited a little later than normal and when I went in, I purposefully took the last shower stall on the right. About halfway through my shower and right as I started to get hard I heard someone come in and take the stall directly opposite me, which I not only thought was really odd, but I was mortified. When I finally got the courage to turn around (still semi hard), I noticed this gorgeous bi-racial guy opposite me, facing me, and soaping up and stroking his damn near fully hard 9" dick while looking directly at me; and he had a damn nice ripped body. I'm more gay than straight, but I was so terrified, all I did was turn my chicken shit ass around and acted like I didn't see it. To this day I still regret it.
