I have a very fond memory of fucking a lover over a decade ago on a pedestrian overpass over a major road in my city.
It was night, and there were no lights on that overpass at the time. She and I had been dabbling in public sex, and when we saw how few people there were in the park I pressed her up against the railing of the overpass.
Hundreds of cars were passing under us, but we didn’t care. We haphazardly got out clothes out of the way, her taking off one pant leg and fucked exactly as you described. It was so stimulating, thinking about what those drivers could see if they looked up and scrutinized our movements.
I made her cum early that night and she was a convulser. It sent me into orgasm but her shaking made me slip loose prematurely, and I ended up covering her pussy in my spunk instead of filling it up as I had intended.
