Back when I was about 16 or 17 I used to seek out adult bookstores. Most of them were downtown so it was pretty convenient to masturbate over my new purchases in the mens room of one of the big downtown department stores. After making my purchase at the book store I would have to almost run to the store's bathroom because I had to take care of my raging hardon. This particular store had three of those old fashioned urinals that you could practically walk in. And on this particular day it was crowded. The urinals were taken and so were the two stalls. I had no choice but to wait. I had one hand in my pocket squeezing my dick. I really needed to blow, so I was going to take either a stall or a urinal whichever became available first. It took me a while to realize that all three of the men at the urinals were masturbating. Just then in walks another man. Everyone at the urinals froze... who knows, this new guy might be a cop. He waited a bit and subtly, started rubbing the front of his pants. One of the men at the urinals who had glanced back, turned sideways so we could all see his exposed hard dick. This new guy unzipped his pants and started masturbating right next to me. The guys at the urinals all started to jerk each other off. I couldn't take it any more. My dick was so hard it hurt. I pulled my cock out and started stroking. Now, all of us were facing each other and pulling on our cocks as fast and as hard as we could. The stall door opened and out came another two guys. God knows what they had been doing in there, but they seemed content to just watch us. We were jacking each other off, first one then the other. Everyone started cumming. I wasn't the first to blow but when I did I almost fainted it felt so good.

I'd come back often and have some nice sessions with one or two guys, but never was it ever like that again.
