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.
