Was jerked off on top of a building in the city by a buddy. Squirted on the pavement below.

Junior high art class.

In my army days I was stationed near Venice, Italy and one day on a very crowded bus to the Lido I was backed up in a rear corner of the bus and a young Italian man was behind me in loose shorts. With the swaying of the bus I felt his hard cock on my ass. He didn´t seem to be trying to avoid the encounter so I reached around behind me and with my hand in his shorts began to stroke his fine dick. Well, sadly, the bus ride wasn´t that far and I had to stop. As we left the bus he winked and we went our separate ways. Fond memories remain today.

I once had in a group shower in a gym while others were in there to it made me so horny looking at all the dick around me I came straight away
No one even looked
So I tried it the next time I was in there aswel and caught a guy having a wank will looking at me having a wank so we waited until everyone was gone and helped each other wank off

Ihave jacked off in public restrooms, while driving, in the woods at the park, in my sisterinlaws kitchen, roadside rest stops, at my desk at work, on the coutch at home while wife watched, wife jacked me off in a bar, i just love to jackoff in public places.

I've done it while driving and in a storage unit.

My GF at the time jacked me off in a cemetery once. And yes I ate her pussy. We didnt have time to fuck that afternoon or we would have done that too.

When I was 18 my then gf gave me a blow job and jerked me off while my mom was driving me back to college. I asked my mom to turn the music up so she could not hear the slurping noises,

I jerked in a crowded bus and my cum drenched the butt of a woman standing infront of me wearing a saree.

On the roof of a catholic church.

In high school, a girl I met at the State Fair jerked me off on the Ferris Wheel. That was pretty strange I think.

Along side a dock at night

I jerked off in a hot tub at a camp ground while two women were sitting about 20 feet from me. I pulled my swim trunks all the way off so I was completely naked in there, as they looked my way a few times it got me excited and I blew my load hard. As I finished they climbed in the hot tub sitting on the other side of me. Still with a hard on from the thrill of it one of them said what is that white stuff floating around.

The church office I worked at for a few years. Had a few close calls, positive the pastor caught me once

That must have been quite an explosion under the desk in English class for the original poster as his account has exploded and he has closed it.
On a more edifying topic the mention of the English class is interesting in itself. Going by the atrocious grammar, spelling and punctuation of kids nowadays the question can be raised as to whether English and literacy are taught in schools any more.

In my church basement

not weird but wanking at work is a favourite for me, you get the enjoyment and get paid for it

I did it in the whirlpool tub in the locker room in high school after practice while others were all around. But with the water moving nobody could tell I was doing it. That was pretty damn exciting
