When I was in college, I got fucked in a botanical garden after hours by a security guard. Very atmospheric.
My ex also had me suck him off in the car on a long road trip, parked at in an empty church parking lot. He also tried to fuck me in a random shady bar bathroom in the French Quarter of New Orleans, but that felt a little too scary.
At the peak of a bridge on the pedestrian walkway at late evening. We were “snuggling” while enjoying the view, leaning against the handrail. She had a skirt on making things easier. Best part is it wasn’t planned. Just happened spontaneously in the moment.
