Last summer I attended a three-week workshop at a large university. To cut costs, I shared a dorm room with a nice guy from Princeton. He's one of those guys who always looks good without ever trying. We teased him mercilessly about his outfits. He even changed his watchband each day to match his shirt.
They worked us hard each day, and I slept like a baby most nights. One night, however, I woke up for some reason and I could hear my roommate's heavy breathing. As luck would have it, his bed was near the window and the moon shone brightly. I could see that he had pushed down his covers and was stroking his cock. It didn't take him long. His breathing became irregular and I could see his cum sparkle in the moonlight as he stroked to orgasm.
He fell asleep-at least I think he was asleep-soon thereafter. Then it was my turn to work my dick. It felt so good to cum knowing my roommate might catch me. I wiped up the sperm with a pair of boxers and immediately fell asleep.
