I realize the OP of this may or may not be female, and it’s fantasy, but I’ll give a different perspective on this as a couple who tried it.
1. As someone else mentioned, there’s a huge risk to guys doing it public, with the exception of the complete pervert, it’s not likely to happen. If you want to do it in full public, make sure you have it arranged with the guy first.
2. If it’s something you want to try with complete strangers, go to an adult theater, just be prepared.
Our perspective on it. For several years, I’d often peruse porn on my laptop at night, the wife would cuddle up and watch with me.
In 2019 I stumbled on a porn series called “Cinema Gropers”, it’s obviously staged videos of women being groped in a cinema setting by supposed strangers. The wife and I would watch these videos then have sex, it was obvious she was getting turned on by them.
I asked her if she’d try that, allow herself to be groped by strangers. She said maybe. A few weeks later, we were at a local adult book store that had an arcade and theaters attached. We didn’t do it then, but it set the stage.
A couple weeks later, we discussed it, decided to try it. She wore her skin tight pleather pants and a loose sweater without a bra. We went out for brunch first, she had a ******* with to ease her nerves.
When we went to the theater, we wandered the store first, then bought tickets. They had 4 regular theaters, 1 showed only gay porn, 2 showed different heterosexual porn, and 1 showed trans porn. We went in each screen for a few minutes, then settled on one regular porn movie.
There were 6 or 7 guys in the theater, she and I stood to the side for a few minutes, then sat down. She tried to relax, her hand on my leg. After a few minutes she squeezed my leg, I glanced over and saw a guy seated behind her touching her shoulder, moving her sweater aside. When we didn’t stop him, he came over and sat beside her. He then played more, started to grope her breasts over her sweater, then got bold and pulled it down and started to suck her breast. She was freaked out, but keeping it together. Then the guy got aggressive, first he tried to put her hand on his cock, she pulled back, then he tried to rub her pussy over her pants, she said not yet, he then went under her sweater to play with her other breast, then suddenly tried to go down her pants. She said stop, he didn’t, I had to intervene, she jumped up and left and wouldn’t go back in. That place went out of business during Covid.
Last year, we went to a different place, it only has booths and two small theaters. At first she was ok, but a couple guys were “aggressively staring” at her in the small theater we were in, making her really nervous. We walked around, looking for a booth that didn’t have a gloryhole, she was wearing a sundress, so her ass got felt up a few times. The first booth we went in had a hole, she was ok at first, then a guy reached through to touch her, making really lewd comments, she slapped his hand away and rushed out. We then went to a different booth without a hole, a couple guys tried to push their way in with us. We haven’t been back.
That’s the real risk with adult theaters or arcades, guys being too pushy or aggressive and not understanding limits.
Just our thoughts.
