"Need a piss, mate?" A casual greeting in a filthy public restroom belies the filthy desires about to unfold. Two homeless men, rough and rugged, catch each other's eye in the mirror. One smirks, unzipping his soiled jeans to reveal a hardening cock. The other, intrigued, joins in, pulling out his own thick, veiny member. They stand side by side, jerking off, grunts echoing off the cold, tile walls. The smell of urine and sweat mingles with the heady scent of their pre-cum, creating a potent, dirty symphony of gay cruising.
