When I was a youngster, perpetually horny, I worked at a manufacturing plant after school. Mostly just sweeping and cleaning and such.
I found a refrigerator box that was empty and hadn't been broken down yet. Seeing nobody around, I lifted it up and slid inside it.
I jerked off and sprayed my cum all over the inside of it while people were walking past and going about their work.
Once it sounded like no one was around, I slipped back out of it and carried on like nothing had happened.
Did that several times over the couple of years I worked there. Never got caught, thankfully.
Made for some good jerkoff sessions tho. All it would have took was for someone to decide it was time to break the box down, but everybody seemed too busy to worry about that.
A few times, I even took my broom with me and eased the handle up my ass while jerking off. That was difficult to maneuver without making any noise, but well worth it

 

Probably the riskiest and I was caught was at a car wash. One of those self serv drive up.

The lady in the car next to me was bent over sweeping her car out with her ass in the air and was wearing a pair of pink shorts that said “juicy” on them. I’m sure everyone remembers those. Well I enjoyed the view and started stroking. She stood up saw what was doing. Smiled and when back to her cleaning, and flashed her pussy. Damn I exploded and wasn’t sure what to do so I just left

 

Jerked off inside a rail car at a rice mill

 

I had some girlfriends over and we were smoking and drinking and I had my ex come over and put on a show for us.

 

Was when I was staying over at a female cousins house. I was on the floor of her bedroom and I was jerking off under the covers and she asked if I was doing anything and I said no. She rolled over on her bed looked down and pulled the covers off before I knew it. She was like yeah Right your doing nothing and next thing I knew I came so hard

 

That sounds so fucking hot! What would you have done had you gotten caught? What would you have done so I would keep your secret?

 

I did it during the SATs many many years ago. Also did it a few times IN class around middle school, (ofcourse in the bathroom a few times but IN class too). Yeah I was outrageously horny as a youngster. Still want to explore public sex with a partner though, I guess I have fucked in a car several times when I owned a tinted van lol.

 

I jack off outside all the time I love to stroke it in front of females. I find random one and strip naked and stoke the hell out of my cock for them or ill go to Walmart in the changing room strip and stroke it . I've done it drive just pull up beside them driving down the road ,at a stop light ,or in the parking lots some time lol. I love it it's a rush when you got a hot random chick watching you explode all over yourself lol

 

Every public restroom I've ever had sex with another guy in, there have been a lot.

 

A place I've found to be quite exciting has been pools/saunas/hot tubs in apartment buildings I've lived in. The first was when I was in my late teens and I had a job where I worked until about 2am. Coming in from the parking garage I'd always pass the big floor-to-ceiling windows looking into the fitness area. Of course there was never anyone in there at that hour, and in the beginning I'd go upstairs, get my swimsuit and go back down to the hot tub. Later I wouldn't bother with the swimsuit and would use my underwear. It always made me really excited sitting there where anyone could see me, so I'd always take off my suit and sit there naked, often using the jets to cum. It always made me pretty horny thinking that anyone walking past those big windows could see me, and might come in to see what I was doing. No one did, and the risk was pretty slim, but it was fun anyway.

Another building I lived in had a pool and a sauna. I'd go down in the evenings, and it was really rare that there was ever anyone else there. I'd often swim in the pool in just bikini underwear, and if I hadn't heard anyone in a while I'd take them off. It was quite plausible that someone might come along, so initially I'd just keep them in my hand while I swam, but I'd sometimes get more daring, leaving them floating at one end of the pool while I swam to the other, or throwing them out so I'd have to get out of the pool to retrieve them. I'd masturbate in the pool, often using the warm inlet jet, or just sitting on the stairs stroking. I'd also go into the sauna nude, doing similar things with my underwear as in the pool. I'd bring them in and have them near me initially, and later getting more daring with how far away from me I'd leave them, sometimes even leaving them in the changing room. A few times someone came along while I was in the pool but I could always hear them coming before they got there and I had time to put my little bikini underwear on. Once I got caught in the sauna by the building super, and luckily that time I had a towel with me that I flopped over my lap. I don't remember getting caught naked there, but there were a few close calls and lots of really fun and exciting times.

 

Wife was selling sex toys and had a sales " party" at our house. They were giggling n drinking and when I cut through I was asked to stay. Oh could he show us what this or that was for? I ended up naked in a group of drunk horny older women. They wanted me to stroke for them and wife was already naked " demonstrating " one of those double dildos on herself. Soon it was hands or mouths on my cock. I'm sure if they were sober it would not have happened that way ( thank god I bought the good stuff). I ended up fucking a couple of them and wife made great sales that afternoon. Room full of women using dildos
