When I was in Berlin last summer, I lived in a hotel which had those little balconies, just big enough to stand on. They were just separated from the ones of the other rooms with an iron railing, which also faced the street, which was mainly deserted at night.
So once after a sightseeing tour when I was so horny, I decided to jack off. But after a few minutes on the bed, I got bored by it, so I decided to just take the chance and try something new.
I put my boxers back on and stood on the balcony (second floor) shirtless. After a few seconds, I felt really comfortable. So I slipped off my boxers, to free my raging hardon. Everybody in the street could see me completely naked, as there was a lantern nearby.
I put my dick on top of the railing and just began stroking. Sometimes a few cars passed by, which got me really going. But then, there were two young men walking directly on the pavement in front of the hotel, which got me over the edge. I spurted my cum all over the pavement, with the two guys looking at me with big eyes. After that, I felt so good and just laid on my bed and fell asleep.
