As a young man, I had discovered many men went to public restrooms and masturbated while other men watched. Often times this was done through peep holes in the walls separating the stalls. Older restrooms would not have doors to the stalls. Sometimes men would masturbate at the urinals.
I knew some men would play with another man's penis, either jacking him off or sucking him off. Since I wasn't queer, I wasn't touching or letting anyone put their hands on me. I did notice however, when I let another man watch me jack off, I came much harder than normal, but not as hard as I came after watching another man jack off for me. Me queer? Pretty naive, wasn't I?
I was a freshly minted PFC in the Army assigned to a Military Police unit in Germany. While others in my unit went down to GI Jungle to piss their money away on the bar girls, I went to one of the parks I had found where men freely cruised one another. I'm sure things could have gotten sketchy, but hey, I was young and invincible. I was also six and a half feet tall and weighed 235 muscular pounds.
At nineteen, I could easily spend three or four hours in the park watching and being watched. I could probably cum at least that many times.
The military in the 70's took a hard stance on homosexuals in the ranks and actively ran stings on various bars and parks in the area to try and bust those service members. Our unit would be notified when and where most of these stings were occurring so that we could process and transport the offenders. I would check the postings before going out on my own.
It started out as usual, I was sitting in the open stall furthest from the door. A man in his early thirties came in, walked to the urinals and noticed me in the stall. He turned away from me, unzipped acting like he was going to pee. He did not keep the illusion going, instead turning to his left so that I could see he was stroking a fat, yet still flaccid, circumcised penis. I sat up straight, exposing my erection to him so he could see that I was willing to enjoy the show. At this he turned fully toward me. I leaned back, spread my legs apart, and matched his strokes with my own. He then walked towards the stall on my right. Other guys had done that before. It allowed them to step into the stall in case anyone opened the door. Where everyone else would have been more in front of my stall so we could continue watching each other, this man had disappeared from my view. I leaned forward to see where he had gone.
Well, damn. The man had not entered his stall, instead he stopped just short and had turned towards me. When I leaned forward, it put his penis less than a foot from my face. He hadn't grown hard yet although his penis had inflated enough to remove any wrinkles. I did not move away, instead, I turned my head to the right, to face directly at his penis. Truth time for me coming right up.
