Weirdest J/O is one I've already mentioned in another thread:
I was working as a security guard in a really tall office block - like, 30 storeys.
I was on the night shift and doing a patrol. The building was empty. I went to the top of the stairwell, pulled down my trousers and pants, knealt on the floor, pointing my cock through the railings.
I jerked off until I came through the gap, my sperm flying through and falling all the way down the 30 storeys and splatting on the floor at the bottom.
That was fun!
I've also J/O'd in plane and train toilets ... but once I got really close to orgasm by stroking under a blanket right in the aeroplane cabin with people all around.
But I had to go to the toilet to cum cos I had no way of controlling the mess
I like to think no one knew what I'd done, but the "walk of shame" back to my seat, with a bulge still in my pants and myc cheeks still flushed was gnarly! lol
Those stories seem tame compared to some of you guys! I need to think of new weird J/O locations!
