Same here. I came back from drinking to my college dorm late one night (or should I say very early one morning) and went to our communal bathroom in our dorm to take a piss. I heard someone in the showers and couldn't imagine anyone taking at shower at that hour so I peeked around the corner to the shower area. We had gang showers with three shower heads on the wall and no privacy separations, just one shower room. One of the hot guys who was rather shy was leaning up against the wall jerking off. He was so into it he didn't notice me peeking. I stepped back tore my clothes off and threw them in a toilet stall then stepped into the showers with my own raging hard on. He about freaked out, but I grabbed him and said there was no shame as it was a natural thing for guys to do and all of us do it. I told him I had come back there to do the same thing only I wasn't expecting any company. I told him we might as well get off together. It was so fucking hot watching him jerk his big dick and I was shooting in no time. He watched me intently as I came. I told him that would always be our little secret, but when I would see him in the hall sometime, I would wink at him and ask him if this would be a good night for a shower. We became regular jerk off buddies. I would make it kind of a "bro" game, like who could shoot the quickest, who could shoot the farthest and every once in awhile we would help each other out stroking each other for a little bit, but never to the point where it appeared we were both into each other instead of the act. I had some really hot times watching him get off with me right beside him doing the same thing. If he only knew. Wow, makes me hard again just thinking about him.
