This happened about 7 years ago. I only get off on true/or first time stories.
We have a few porn stores in the area, 3 of which in Portsmouth (NH) have movie booths. I've liked getting off in those filthy booths since college. Having first discovered these dark seedy places in college, I got a certain dry mouth, a horny feeling low down that every once in a while I need to satisfy. Every once in a while I'd drive up and pick a place to go in to. The place called the Fifth Wheel was my favorite, don't know exactly why. Perhaps it was more secluded than the others.
Really, I was scared to even glance at the people sometimes standing around and didn't understand the rules. I'd find a booth, pop in some tokens and scan for something I liked. Usually, this was guys fucking. I'd pull my pants down and lube myself with spit. The door was never locked but nobody ever tried to come in and I don't know what I would have done anyway. I'd stroke myself and play with by chest and ass, then blow my wad in the corner, adding my jism to the mess.
Everything changed when the next time I went, the doors had been taken down leaving the booths somewhat exposed for anyone walking down to see (who are these assholes that force these things?).
Well, the idea of being watched excited me but getting caught by a pig wasn't a good plan. In the end, I was so horny and the place was so empty that I took a chance in the last booth. I figured I'd have time to button up if somebody came by.
With no door to hide behind, I pulled my pants down a little and pulled out my hard prick, put in some tokens, and began to beat off. Then I noticed that in the darkness of an opposite booth was another guy, cock out, watching me while he stroked. I'd just hadn't seen him before. He was just watching me and after being startled I didn't feel threatened, seeing that he was getting off too. So I didn't stop and kept right on stoking, hard as stone and way turned on. I guess he took this as an invitation and he came over and asked if he could join me. After years of nothing ever happening, the bastards that removed the doors were actually helping me have my first guy-guy experience.
He was my size, a little older and heavier I think (to my 125lbs of lean skinniness). I wanted to touch his cock and reached for it. It was hard and slippery from spit, just like mine. It was natural, I squatted down and looked at it, then licked it, then tried to suck it into my mouth. He moaned really softly for a moment and I tried like hell to suck that cock as far down my throat as I could. What a feeling. I sucked him for a bit, I think pretty well for a novice, when he pulled his cock out and said he really wanted to suck on me. I pulled my shirt way up and had my pants almost off, basically as naked as one would dare to give him access. I though I'd gone to heaven when he sucked my cock into his mouth and rubbed my stomach and ass. He pushed and pulled me until I was slowly fucking his face when I felt the best come of my life well up. I was shaking like a leaf, and I exploded into his mouth, he wanted me to, and he sucked me until there wasn't anything left. I remember he stood up stoking his cock and blew his load. After a moment he pulled up his pants, as did I. We said good bye and that was it. I've never had a better orgasm.
