First time in an ABS:
It was 1980, I was a tall, thin, 18 yr old Marine stationed in San Diego. This was back when you could drink at 18 and there was no random drug testing. I spent one of my first nights there wandering around downtown in a pot and alcohol induced haze. I was eyeing the prostitutes but didn't think I had enough money for them, since I'd already dropped most of my cash in the strip joints. I made my way into an adult bookstore with a flashing "peep shows" sign. This was back in the day when each booth had it's own movie playing. it was so long ago that I don't remember what movie I selected, other than it was for sure a hetero sexual one, as I had surely never thought of man on man sex at that time. While I don't remember the movie playing, I surely have never forgotten what happened next!
I settled into a very comfortably sized booth, with a bench facing the video screen, and inserted my tokens. Thinking I had locked the door, I dropped my shorts to my ankles, sat on the bench and began stroking my 7" now hard cock. I was so high and buzzed that I didn't even notice the door opening, but a man immediately is on his knees between my legs and takes me into his mouth. In my buzzed state I must have somehow forgotten to lock the door!! At this stage of my life I'd only had sex with one girl, and never had gotten a blowjob. It all happened so fast that I didn't even have time to say "stop I'm not gay". All I knew was that I'm feeling something more pleasurable than I've ever experienced, he was maybe in his 40s, physically fit, clean shaven and his mouth was like velvet. With my balls getting gently squeezed in one hand, he was easily able to take every inch of my cock in his mouth. He slowly worked his way to the base, and I could feel his tongue flicking on my balls. As he slowly bobbed his head up and down, my swollen cock glistened with his saliva. I'm sure that within minutes I was about to have the most incredible orgasm of my young life. He must have felt in cumming... because he grabbed my balls and buried his head on my lap and I pulsated stream after stream of hot cum while feeling my cock at the back of his throat. He drained every drop from my hard cock, looked up and smiled and said thank you and slipped out the door.
