A couple years ago on st Patrick's day I was our at the bar, had been pre drinking so had already drank alot.
We were waiting in line to get in when all those drinks started to weigh on my bladder
I was bursting, and I could feel the piss creeping up to the tip of my cock, so I left my friends in line and went in search of an alley
Luck was not with me, the best I could find was an alcove in a store front
I stepped and pulled out my cock. One of the best pisses of my life. It sprayed hard against the brick wall and ran down and out to the sidewalk.
