Martin and I became friends while we were both theater students in college. Martin and I had just become roommates after graduating. My only sexual experience, to that point, had been with girls. Martin had admitted to having a drunken fling with a guy before, but he too had otherwise only been with girls.
We were in a cheap 2-bedroom apartment, and between us, we shared a TV and VCR in the living room. When I entered the apartment one evening, I had obviously caught Martin getting off to a porno tape he had rented. He was embarrassed, but I shook it off. I added that I wouldn't mind seeing the video with him.
I sat down on the other end of the couch, and Martin took the tape off pause. The couple on the screen went through all the usual porno positions until the "script" had the woman's husband walk in on them. After a minute of terrible acting, the three of them were naked, and the husband made it a 3-way.
At first, all physical contact was limited to guy_girl. I have to admit that as bad as the acting was, the "actors" were gorgeous. Then it happened. The husband mounted his wife, and the other guy positioned himself so that he could lick the length of the husband's cock as he slowly slipped in and out of his wife. I was shocked as I had not witnessed a gay sex act live or on video before.
I couldn't believe that I got hard as a rock watching the video, and it became apparent that Martin was studying me for my reaction. He was encouraged that I had an erection instead of running from the room, so he decided to take things a step further. He pulled his cock out of his pants and started stroking himself.
At that same time, the husband withdrew his hard-on from his wife and repositioned himself to fuck the other guy's throat. I couldn't believe I was watching two guys going at it with the woman wondering what was going on below out of her sight. My mind was racing with thoughts I'd never had before. The biggest revelation was, "Of course, a guy can suck cock better than a girl. He knows exactly what to do."
No sooner had I opened my mind to gay sex, Martin said, "Look at that! The guy knows how to suck a cock!" And so I freed my erection from my pants, and we both took in the gay scene stroking our cocks in rhythm with each other's movements.
I couldn't hold back, and I shot cum everywhere. Some of it spurted to the side and landed on Martin's arm. He stopped stroking himself to wipe it off with his finger. And then my view of gay sex changed again. He began sucking on his finger while he looked at me with a wicked smile. I immediately went from "I am really not sure about this" to "I want to suck this guy's cock and see what it's like when he cums in my mouth."
It was as if Martin could read my mind. He didn't say a word, but he started removing the clothes he still had on. I followed his lead. There was Martin with a magnificent hard-on waving like a flagpole, his legs spread apart and signaling for me to kneel in front of him. He didn't need to ask twice.
When I got positioned in front of him, I started doing all the things I had wished girls would have done when giving me head. I cupped and caressed his hairy balls with my left hand while grabbing his manhood with my right. My mouth stroked his cock, matching my hand movements as my tongue went crazy over the head of his cock. I worked his manhood with a pent-up fury I didn't know was inside of me. His involuntary moans turned quickly to gasps, and then all he could say was, "oh God, oh God, oh God" until he gave me his load. He yelled and grunted as his cock erupted down my throat. I was doing my best to keep working him for all I was worth while trying to swallow. The torrent of his cum escaped my lips and spilled down my hands and his cock. I'd never felt so sexy in my whole life. I was in heaven.
