I was around 26 or so. Married. Wife was out of town and I was working late. It had been a few days since I had a chance to even jack off, so I was overdue to blow a load. Decided to visit the local adult bookstore on my way home to visit the video arcade and stroke out a quick load. The only booth available was one with a gloryhole, although that wasn't what I was looking for.
I slipped money into the machine, found a video, unzipped and started jerking my cock. I noticed movement in the next booth through the gloryhole, so I decided to peek in. It was another married guy, white, around 35 or so. He was standing up, pants around his ankles, slowly stroking to a bi video. He had a nice cock, about 7 inches or so, cut. Big balls. Thick pubes.
He must have noticed movement on my side of the wall, because he turned to face the hole. He just stood there for a few moments, and I watched him jack off slowly but deliberately. He was putting on a show, and I definitely enjoyed it. I knew I had bi inclinations, so I had read up on gloryhole etiquette, but had never had the courage to do anything about it until then.
I slipped my left hand through the hole, making sure he could see my wedding ring, and then withdrew. He slid his cock through the hole and I decided I'd give it a go. I took his cock into my mouth and started bobbing up and down. He slowly thrust his hips back and forth, and it wasn't long before he shot his load. In fact, he came rather quickly, which I didn't mind.
His cum was warm, a mixture of salty and sweet. It wasn't a big load ... I suspect he had already cum once, earlier, although it didn't taste or smell like he had. Either way, I couldn't bring myself to swallow, being my first time, but I remember feeling very satisfied that I did it. It was like losing my virginity again.
He pulled out of the hole, bent over to pull up his underwear (blue briefs, as I recall) and pants. He watched with fascination as he tucked his cock away, buttoned and zipped, and left the booth. Only then did I actually finish what I actually started ... I sat back in the chair, gave myself about a dozen quick strokes, and made a cummy mess on my shirt.
Then I went home, took a shower and jerked off about three more times.
