Growing up In St Catharines I became aware in my 20's of the Pine St Cinema in Niagara Falls New York. I found out about it because it was only a few doors down form Pete's Market house that way back then was a really good steak house/butcher. The first few times I saw it I was unaware that it showed porn movies but one time I ended up parking past the theater and as I passed seeing the signs for the movies showing realized it was an "adult" theater.
After I had had my dinner and a couple of drinks I went into the show. Like most porn theaters the clientele was overwhelmingly male but there were also a few women there with their husbands, boyfriends whatever. The layout was a little odd because they had a section of booths at the front of the theater when you went in and so on entering the main room the left half was blocked off for about 10 rows but then opened up. The right side had rows about 6 seats wide for the first 10 rows and then the aisle split the seating for the rest of the way down to the screen.
As my eyes became accustomed to the dark it became clear that the back rows on either the right or left side were populated pretty much entirely by men although certainly not crowded and that a few of these men were sitting beside each other closer than was needed because for the numbers. Further snooping made it clear that some of them were getting hand jobs from their neighbours and some were even getting blown. Altogether it was my kind of place.
I moved down to the left side of the theater and sat in the second last row there over against the wall. There were a couple of guys behind me to my right from where I was sitting and as a split my attention between the porn on the screen and them it became clear that the one was jerking the other guy off slowly and then I saw him lean over and start sucking him.
The action wasn't really overt everyone was being fairly discreet about what was going on and I was soon hard as a rock wondering if I was going to find any action that night.
About then a couple, male and female came into my row and I was a bit surprised that they sat right beside me with the woman between her husband and me. They were probably mid 30's and she was quite pretty without being a real beauty. She had on a mini skirt which was pretty common at the time and a blouse over it. Nice legs and nice tits and a well made up face. Her blond hair was obviously bleached but her perfume was nice and the 2 of them settled in and seemed to be engrossed in the movie.
As we sat there her arm brushed against mine at the arm rest and not knowing what else to do I moved mine and surrendered it to her. I started paying attention to the show when I realized that her leg was now pushing against mine gently and so again I moved over a bit to give her more room at the same time thinking it was a bit much her sitting down and then inching into my space. A few moments later I felt her leg against mine again and this time looked down and realized her knees were about 5 inches apart as she sat there. It was also plain to see that her husband was stroking the inside of her right leg between her knee and the hem of her skirt. She noticed me looking and just spread her legs a little more. That seemed to be a signal for him to run his hand up a little farther between her legs. Suddenly I was very interested instead of bothered by her encroaching on my seating area.
They went on like that for a few minutes and then I felt her hand brush my knee as he continued stroking her other leg. She looked at me and smiled and brushed over my knee again. By now I could easily feel the heat of her lag against mine and then she slid her hand up the top of my thigh back down near my knee and then up the inside of my thigh till the side of her hand was wedged against my stiffening cock. When she felt that she moved her hand over my cock and gave it a firm squeeze and at the same time turned to me and asked if I minded. I certainly did not.
