In the town where I grew up there was an infamous adult theater. It was an old neighborhood movie house but after the advent of television, it was converted to an xxx movie house. I always wanted to go to see what happened there, and friends told stories about old men in trench coats. I was terrified to enter. For one thing I didn't want anyone to see me going in. Shortly after my 19th birthday I finally worked up the courage. On a week night at about 7:00 I bought a ticket and entered.
The place was so dark that my eyes took several minutes to adjust. As I hesitated near the back, shapes of men slowly came into view. The rear row was almost filled and as I looked I could see that almost everyone in the back row was masturbating. The image was arousing but scary for me so I wandered up a few aisles and took a seat in a row by myself.
Long before I sat down I had a raging erection. I'm not sure what was sexier, the movie on the screen or the activities of the men around me. Trying to be subtle. I opened my fly and began to touch myself. As I watched, I began to notice that the front row was also filled. I stood and moved closer to the front so that I could see, and also became bolder, taking my penis out of my pants. After a few moments an older man sat next to me. I quickly hid my penis, but he knew what I had been doing. He took his penis out and began masturbating and signaled for me to do the same. Following his lead I took my penis back out and began to stroke myself slowly. As I did he moved closer to me to watch and then touched my thigh with his hand.
The whole thing was just too sexy and I lost control, squirting my load all over myself. He leaned into me and laughed telling me that I was going to have to learn how to last a bit longer if I was ever going to satisfy a woman.
I got up and rushed to the mens room to clean myself and then left the theater with a terrible mess on the front of my pants. I told myself as I left that I would never do that again.
