In the early 70s Adult Bookstores in my home town were thriving. I ventured in too watch some porn a couple of times but only jerked myself off to the videos.
One afternoon, place was busy so ended up in a booth with a hole in the wall, now I new what it was for but had never tried one, as I sat there looking a porn a finger popped through the hole, so I pulled my cock out and poked it throught he hole. A mouth quickly surrounded it and I did not last very long.
I found that very exciting so thought I would try it again another day. It was middle of the week, I was working nights so came in a little early and headed to the my favorite bookstore.
As I enjoyed some porn there seemed not be be any action, so I peeked through hole to see guy jacking off, since my first adventure I poked my finger through the hole and next thing I new a nice cock came through the hole.
I started sucking it and could feel the guy fucking my mouth, shortly there after I could feel him cum, it was very tasty and I was officially hooked to glory holes.
The excitement of sucking some strangers cock, unknown to you was intense. So I hung around and watched some more porn and soon I heard the door open, it sounded by the laughter and stuff that there was more than one guy in the booth, after a few minutes I looked through hole and saw a young guy sucking another man, I watched for a few minutes and then put my finger through the hole.
Shortly thereafter, a cock slid through and I started sucking it, after a minute or two he pulled out and another, larger cock came through, I started sucking it and was really surprised when I could feel the other guy was fucking him as I was sucking him. He started groaning and I new he was ready to cum so I started sucking faster. After he came, I could hear the other guy grunting and new he had cum, wow, much more than I expected.
I continued to go to the bookstore more often and became friends with the clerk, he would tell me when I best times to come in were and we even enjoyed each others company. Being bisexual, I usually watched hetero porn, but he got me turned on to gay porn, I fantasized about some of those well hung men.
On several occasions what started out as a hidden blow job turned into an afternoon delight at a person house or apartment, I was only in my early 20s and found 40s and 50s men enjoyed my company, I also enjoyed theirs. I even got fucked in one of the booths, and not being able to lock them was sort of a turn on, the door opened a number of times when I was in action and made me even more excited.
