My first college roommate was a guy I knew from back home. Our rooms were small. For the first few nights I tried to j o with a minimum a noise and the restraint actually added to the excitement of it at first. I could tell he was sometimes jacking off too so one night into the second week I said quietly into the darkness between our beds "I'm going to whoop it up here for a while. I hope you don't mind." He answered right away "I'm right with you" and from then on we were open about it.
I thought he was straight. I still think that for him it was "situational" but after about a month he asked me if he could feel my hard dick and so I felt his, too. It was the first time I felt another man's dick and to tell the truth it didn't do much for me. He was circumcised very tight and I was afraid I was going to hurt him but he showed me what he liked and I tried to oblige. I'm not sure I got it right but I wiped plenty of his cum off my hand over the next few months. Some time before Christmas while I was jacking off alone one night he came over to my bed and knelt beside it and leaned over and took my dick in his mouth and gave me my first blow job. We kept it up all year though both of us had girl friends. It was a church college and there would have been hell to pay if anyone had the least suspicion about us.
The next year I had a different roommate who was a couple years older than me and who I never even hung around with. We had a big room and our beds were far apart. One night when I was quietly jacking, trying to be discrete, I felt him looking at me and when I peered across the dark room I could make out that he was holding his head up with his arm and hand, looking at me in the mostly dark room and quietly stroking his own dick. I just pretended I didn't see him and hung in there, edging and holding back for probably 40 min. When I finally came he came too. He was "straight", never admitted verbally that he even jacked off, but he developed a kind of fixation on me and I never knew why. He always followed my lead. If I stayed up late, or stayed out, he'd wait til I came in and went to bed to go himself. Lights out and he'd wait in very pregnant silence for me to stir, to turn, to breathe steady, and then give my dick a tentative touch. He was always following my lead and I know he got off on watching me. One night I stirred awake in the middle of the night and he was standing by my bed with his jockey shorts down to mid-thigh, looking at me, pointing his dick at me and jacking off. That seemed kind of creepy and I wanted to move anyhow so I found an apartment of my own. Neither of us ever mentioned out loud that at least every other night we jacked off to the same rhythm in the same room.
