I was in bed with another guy. Our college student group had just finished a two-month tour and on our last night before returning home, we stayed in a motel. Two beds and four guys to a room, so an old roomie and I took one bed.
When we had roomed together, nothing ever happened between us. He'd make some comments on occasion, but nothing terribly far out of the ordinary for a guy. But this night turned out differently.
I slept deeply, more so than usual, since I was exhausted from the tour. In the middle of the night, I awoke to a strange hand in my underwear stroking my cock, which was already hard and pulsing to his touch.
At first, I was scared. Never had anybody touched my cock but me. I had no warning, no preparation. Here I was in bed suddenly with a hand on my cock, and two other guys in a bed beside us who'd likely not approve of what was happening.
