My girlfriend and I were rollerblading (1996) in the high school parking lot and this kid who always followed her around like a puppy was annoying her. She had me sit down and she sat on my lap while she got me inside her and started riding me. As he came near, she lifted her skirt so he could see what was happening, and he ran off, shocked.
So, got ridden on school property while in Rollerblades by my GF who was also in Rollerblades.
Only slightly more tame was when we went outside at a party and had sex on a little hill in the garden of what we thought was the back yard, but turned out to be the front yard with dog walkers going by. Both party goers and pedestrians were cheering us on when we realized we weren't exactly private (which was our intention for slipping outside). Tame because at least it was dark outside, but perhaps less tame because we were drunk and thought we were "alone" at first.
My first kinky GF was a highly experienced community kinkster while I was this vanilla nerd. She connected me with her ex Mistress who provided kink mentoring so I could be the Dom my GF wanted and needed. But it was hard for me. About seven months into our relationship the Mistress tasked me with walking my GF leashed through Kenmore Square on a Saturday night when nightlife was popping. She was dressed in fetidh gear and collared while I wore a suit.
And oh yeah, eyes turned toward us from all over the street.
It was harrowing and embarrassing for me. Which was the point. To get me to confront those feelings, control them in public, and walk tall.
I should add, many community kinksters these days would consider a public display like that to have violated everyone else on the street because they didn't consent to see it. But back then (late 90s), the kink community didn't hold such views.
I think that's a North American thing, because just before Covid I saw a leached woman being walked along the Champs Elysees in Paris. Nobody batted an eye. Lol
My wife and I love going to the nearest local taboo show.
This year she was visibly showing with her pregnancy bump, but decided tomwear her leather top, kink heels, hobble skirt, and top it off with a pink collar and leash.
She wore the leash and collar through the link convention, getting lots of appreciation and looks. At the end of the con she wanted me to walk her back to the car, a 10 minute walk through downtown in public.
Couple of dog whistles, lots of glances. Was really fun.
I was hiking with my partner and we weren't into the hike but into one another. So we hiked a little bit off the trail and got it on. The situation had me so turned on that when I came I roared like a wild animal. I wonder what sort of animal the other hikers nearby thought they were hearing. ;)
Had sex covertly on a public beach while there were still people there. More than once. We're just so horny for each other when we're in our swim wear that we can't help ourselves
While on a roadtrip with my bf, I got naked and fingered myself in the passenger seat while he was driving. We later stopped and had sex in the backseat on the side of the highway.
It depends on what you call "in public": discreet/risky sex in public places, or sex in front of others in dedicated places?
In the first case, I had sex in a car in the parking lot of the university, on a friday evening after class. An other time it was in a vineyard (she started to wank me while I drove. Safety first, I found a place to park the car on the side of the road). I fingered her at the beach, and some other day she gave me a handjob at the movie theater.
If you talk about dedicated places, I've done naughty things at the local gay sauna (I'm bi, in an open relationship).
The most nsfw was probably a foursome in the steam room. It started as a regular 1+1, and other guys joined the band, one after the other. That was fun.
The wife and I had sex on the beach. It was early in the morning, so nobody was there, but shortly after the big finale, the dog walkers started their rounds. We took some photos and then left.
