I've done it on the train a few times but the riskiest was probably on the couch in someone's living room where I was supposed to sleep after a birthday party.

In train toilet cubicles many times
Riskiest though is the top deck of a bus and once on a coach

A hotel balcony overlooking a busy high street. The balcony was 5, possibly 6 stories up and when I came it was over the rail onto the street below.

Nice 👍 perving on passers by?

At a friends place after they went out for a quick stroll. Almost made a mess.

In my car staring at a hot blonde in the car beside mine.

Middlesbrough

In the library when I was in school, sitting in the back study area. The potential of getting caught was so exciting that I came very quickly, blasting my load onto the floor under the desk.

A little too high to perv but the exposure was exhilarating.

Love wanking in different places. 1. Toilet cubicle. 2. Many years ago at my girlfriend's parents house I would go to the bathroom and have a one minute wank then go back to the lounge. Did this s of times. 3. Standing at the bedroom window watching for our hot postal lady doing her rounds and try to cum just as she walked up our path. 4. Swimming pool changing cubicle. 5. Sitting waiting for my wife to come out of her work and wanking in the car with my hand in my pants and cumming in my parts. 6. In my parents lounge after they had gone to bed,very often. 7. In my bedroom but with the door open and my sister in the next room. Went wrong, or right, a few times and I got caught. 8. At the bedroom window watching some hot women sunbathing in their garden. 9. My girlfriend of the time dared me to wank off while we were waiting for her landlord to turn up when she was moving out of her flat. I wanked in the lounge as she watched and the front door was wide open. Cummed a big mess on the carpet, do nice. 10. In the middle of the night living at home with my parents, would wake up, go for a piss and then sit and wank off in the bathroom with the door wide open. Went wrong, or right, ages times and got caught. So much fun.

In my sister's bedroom totally naked whist she was downstairs.

at work, many times, with the front door unlocked. Twice had people come in so i had to pull my chair real close to my desk so they wouldn't see anything.

my profile pic is at work.

In the middle of a mountain road late at night, stark naked. I'd locked my clothes in the trunk of my car, so I would have been unable to get them on in time if anybody saw me. The risk was a huge turn-on.

In the middle of an Interstate, cars passing, horns honking and even a few stopped to take pics. Pumped out a load then ran away before the constables got to the area, but not before a lot of people saw me.
