My first wife and I were both on the exhibitionist side, and decided one of these theaters would be fun. We found one through some friends, it was in a run down part of town but it was pretty much anything goes inside.
At first we started with the booths. We'd squeeze in, she used to wear these one piece outfits with no underwear. As we watched the dirty videos I'd start by undoing the clasp in back and rubbing her back. Eventually I'd slide the front down, exposing her tits, and playing with them. When she started to move her hips back and forth I knew she was ready, and I'd slide her outfit down and off. Fully nude now I'd reach around and play with her until she came. She'd then get down on her knees, pull out my dick, and either blow me, tit fuck, or most often a hand job.
We did that for a while, then I convinced her to try out the bigger theaters in the back. For 20 bucks you could go in and stay as long as you wanted. There was a long hallway with four theaters, the biggest wasn't labeled, but was anything goes. There were three smaller ones that did have signs, "Couples only", "Ladies only", and "Men only". The only thing they would kick you out for is being in a theater you weren't supposed to be, i.e. a guy in the womans only room.
As I said, this place was anything goes. It wasn't unusual to see people going from one theater to another fully nude. The hall was piled up with peoples clothing, as were the back rows of the theaters. We started with the couples room, sat in a back corner, there were never many couples in there, I think 4 others was the most we ever saw. I worked her clothing off, she got mine off, the first few times we masturbated each other, but got to where sometimes we'd actually go all the way.
It got to where she so got off on the exhibitionist part of the action we'd get naked in the hall like so many others. Sometimes we'd split up, she'd go in the ladies only, I'd go in the men only, we'd have fun masturbating then join each other in the hall and share the fun we'd just had. We'd get turned on and go into the couples room for more fun. Sometimes during the week when I was at work, she'd go by herself to the ladies only area, usually in the morning. She said there was rarely anyone else there, although she would see a few regulars. A few she became very friendly with.
Fast forward some years, shortly after moving to my current city first wife and I separated, then divorced. I found a local ABS I liked and used to visit fairly often. It wasn't divided up like the one I used to go to, this one had one theater, but like the one back home it was very much anything goes. Most guys left their clothes near the entryway and enjoyed naked fun. Mostly it was guys solo or giving each other hand jobs, you'd see blow jobs as well, and on rare occasion full out guy-guy sex. I only saw a woman in there once, she was wanting to be the center of a circle jerk. Boy did we soak her down.
I had a weird job schedule, so was often able to go there during the day, when there were just a few other guys in there. Those were my favorite times, as I could enjoy solo pleasure if I wanted, but could easily hook up with another guy. There was one fellow who was a regular, he and I often jacked each other, or sucked each other off. We even got to be friends and saw each other away from the theater.
Sadly the internet killed off most of these places, they all seem to have closed. I suspect the cops had something to do with it too, there was a "decency" push a while back that tried to "clean up our city". LOL. If only they knew how dirty it was behind closed doors.
