Personally, I usually find the idea of public restroom (i.e. parks, train stations, airports, etc.) sex to be unappealing. Nightclub restroom sex, on the other hand, is a different matter. I recommend the Ladies' handicap, as it is usually the largest, and has all those railings for both of you to hold onto while you are pounding hard.
But I digress... There was one episode of public restroom sex, which while it was truly disgusting, was somehow very, very hot for me. In the old days, there was a notorious public restroom, or "cottage," on the Midsummer Common in Cambridge, England, near the roundabout intersection of Victoria Avenue and Maids Causeway. (Years ago, it was replaced by this futuristic football-shaped pay-toilet facility, presumably in response to the sexual activity at the old cottage.) As it happened, I was frequently in Cambridge on business, and would get lonely. Despite my aversion to restroom sex, the cottage was always a reliable place for a quick BJ or other emergency draining of the balls, so I would swing by as the need arose, despite the slovenly nature of the place.
One evening, in need of a BJ, I entered the cottage and proceeded to take a hard beer piss at the floor-length gang urinal. This skinhead in bleachers walks in, sees me, opens his eyes wide, and says "Oi, mate! Could you fuck me?" So we made our way to one of the stalls, which were quite private, as the walls were concrete, and the heavy metal door extended floor to ceiling, like a regular room door. The stall, however, was absolutely disgusting filthy. The was litter and god knows what all over the floor, including a number of spent syringes. Indeterminate liquids had dribbled down the walls. The toilet was filthy. The skinhead lowered the smeary black toilet seat, at which point I observed that there was a big clump of, um, most likely shit adhering to the wall directly above the bowl. I was going to suggest that we use the other stall, but he was already bent over, gripping the filthy toilet, bleachers down around his knees. His hole seemed decent and clean, unlike the surroundings, so I pulled on a rubber, spat out a big wet gob to lube it, and plowed in.
I have a big, thick dick, and fuck hard. As such, I was driving his whole body forward with each thrust, as he supported his weight on his arms above the filthy toilet. It was at that point I noticed I was driving him forward to the point where his face was approaching just millimeters (and perhaps sometimes closer) from the clump on the wall. I didn't know if I should be repulsed, or turned on. Apparently it worked for him, however, as after a few minutes his hole tightened around my cock in a death grip, and his whole body shuddered violently as his pumped out his load. I waited for the spasms to stop, then pulled out. He stood up, revealing the dirty black toilet seat, now thoroughly decorated with white streamers and pearls of his copious seed, and his cock still dripping more of the same onto the floor. I pulled off the greasy XXL condom, and tossed it onto the floor among the other detritus. I surveyed the stall as I buttoned up and opened the door. It was a scene of total destruction, punctuated by obvious sexual excess. I felt quite satisfied, even though I did not unload myself.
