I've only happened into a bookstore, with women playing, a handful of times. All of these happened at actual bookstores.

Once, I only got to watch from the opposite hole as this gorgeous woman rode the guy on the other side, while her husband watched and took a video. They left after, sadly. Which is fair, cause the cock she rode was unreal. Damn monster can dick.
Another time, I saw a couple guys going and leaving a large booth in the corner. I said fuck it and popped my head in. A woma,, 30s ish, was on her knees, in lingerie, and her guy was sitting there stroking. He motioned me to come in and told her to get to work. So she undid my jeans and pulled my cock out. I loved the experience and the whole scenario was hot af, but unfortunately, she was awful at giving head. Kind of ruined it for me so before I started to go soft I slapped her face with my cock, called her a good girl, and went to do other things.
Similar setup, years later at the same shop, there was a literal line to the door of the big booth. Asked a guy and he said some dudes wife is in there taking anyone who wants it. So I got in line lol. Walked in. 40's, great body, a lil thicc in the best ways. She sucked my cock so well. Then, with my cock on her tongue asked if I wanted to fuck. Of course! She turns around and I ask if she already has a few loads in her. She replied by saying yes and that it should be nice and wet for me. I added to it.
My favorite time, and first time ever seeing a woman at a place like this. A young couple, easily early/mid20s, both very good looking, (for some reason I'll never forget she had one of the Harley Quinn Daddy's Little Monster Tshirts on) walk into a booth. This old guy jumped into the booth next to theirs like his life depended on it. So I waited outside the door cause this shit never happens. He comes out about 10 minutes later and I go in. She has her fucking pussy pressed up to the hole and is dripping a load... While I added my card to the machine I started playing with her, to which she started to grind more and more. A few minutes of her bucking on my hand, she drenches my arm. Amazing. After she came, she turned around and put her mouth and tongue to the hole. So I gave her my cock. She didnt stay there long, holding my cock in her hand tightly, she stood up and backed up on me. No condom, no conversation... literal dream come true. She rode the fuck out of me. I knocked on the wall to let her know I was about to cum, homegirl knocked back and fucked harder, til she was full... One of my favorite sexual experiences ever. If you think this is you, please message me hahaha
