There are patrons at many ABS/GH venues that network with owners/staff who text or call an 'alert' when there is female/couple traffic. Same holds true for certain other visitors; twinks or femmes...
There are so few venues now, anywhere I know of, that have actual gloryholes. Between culture wars, aggressive law enforcement, and the pandemic, very few of these venues seem to have survived. In our region, the places that are still going have tried varied approaches to broadening their clientele. Some have large, private booths that will accomodate 3 - 4 people and still have room to move. Some have small, open-seating theatre spaces, or spaces with lounge furniture for public play. At least one we visited had private rooms, by the hour, six hour max, sort of gay sauna style.
Glory holes are closed in my city. A few adult bookstores have theaters along with the arcades. The arcade booths are small. Theaters are better, but are hit and miss regarding m-f couples. More likely you will find men who want to give or receive oral, sometimes anal. M-F couples and even single women going to the theaters was more common before Covid, but has mostly tapered off now. I know that at one theater, one guy used to hang in the parking lot to see if a m-f couple or a woman entered the theater. Then he would pay to enter, but not before. One time when he arrived at the place, he asked the clerk if there were any women or m-f couples in the theater. Clerk said no, so the guy went outside to the parking lot. I would not be surprised if there was an alert network to inform friends when women were there.
I sometimes thought that some of the women and "couples" at the theater were prostitutes paid by management to drum up business. One time, a black guy who was a regular patron came there with 2 women who looked like pros. They gave him oral and everyone applauded when it was over. They then left. I think the hope of seeing women or couples at the theater helped increase the number of guys paying to enter.
There were real m-f couples that went, still are but not as many. The men at the theater would follow them all over the theater, never give them a chance to feel comfortable. It was like a pack of dogs crowding around a piece of meat. Some couples might have been ok with it, but others become uncomfortable and left.
Once, a married couple was there. The same black guy that I mentioned was there. It almost seemed like an arranged meeting, but I'm not sure. Husband stood by to keep the other guys away while the wife opened her blouse for the black guy to caress her breasts. Nothing more happened and the couple left. I saw the black guy in the parking lot and asked him about her. He said that she was a nice woman, but I couldn't get any more information from him. Don't know if she was having sex with him regularly or they just met for him to fondle her in front of hubby. She was pretty, middle aged, appeared like a conservative MILF, and looked very desirable.
Here is one of the craziest things I saw. A younger couple came in during the afternoon. There were not many guys there. The young guy bent her over a seat and f--- her some. She then shouts to us that if a guy gives her money, even one dollar she will give or let him f--- her. I don't think she was a prostitute. I think she had some kink where she wanted a payment, even as little as one dollar. She was really pretty. No one took up her offer. I wondered if it was a police sting to arrest men for soliciting, although her boyfriend screwing her would been an odd part of a police sting. One of my buddies said to me, "Why pay her anything when you can easily get oral or anal for free from any of the men." So true.
Another time, a m-f married couple was there. They were middle age or older. She ended up removing her loose dress and letting a black guy f--- her from behind. (Not the same black guy I mentioned earlier.) She turned her head around around and thanked her husband for letting her do it as the black guy pounded her. I thought that was the best part. Anyway, when the black guy was done, she put the dress back on and sat down next to a younger black guy. He tried to caress her leg and she freaked out. Said something like "that's enough, I'm not putting up with this." And she and husband stormed out. She had just been naked and had sex with black guy #1, but then gets angry when another guy caresses her leg. Strange.
The was a m-f couple that frequently went. The guy was either from India or the Philippines. She appeared Chinese or from Southeast Asia. He had a bag of condoms that he gave to all the guys that wanted to have sex with her. She calmly took them. As for the guy, he wanted men to give him oral. Interesting m-f couple to say the least. She was really pretty, mature, again appeared like a conservative MILF.
There was a woman, I think married to one of the guys in a group of men who escorted her into the theater. She and the group were regulars on the weekend nights. The group included the black guy I mentioned above and parking lot guy. She dressed in lingerie. She was tall and thin with small breasts that had dark aureolas and nice nipples. Bleached blond, mature, once again could be a conservative MILF in everyday life. Anyway, the guy who I think was her husband masturbated on her leg. When he finished, everyone applauded. Again, I had to wonder if they were paid to do this. One of my buddies told me they were a real married couple and that she would go to the parking lot and let any guy have sex with her as long as he used a condom. No payment required from the men. But, did the ABS/theater owner pay her? Wow. By the way, the owner of this particular theater used to produce "amateur" porn.
A woman used to go to the theater alone, but be in cell phone contact with her husband. She would describe everything that guys were doing with her. One of my buddies warned me to be careful as he thought she was full of STDs.
I even heard, but never saw, of two women who would go to the theater late on a weekend night, like around 2 am. They would lie on the floor and have all the guys stroke over them and dump spunk on top of them.
Unfortunately, those days seem over in SoCal. If I had known about these places when I was young, I would have tested girlfriends out by bringing them there for a trial run. If they were slutty and kinky enough, I would have deemed them proper for a long-term relationship. Hindsight is always so clear.
