Two strangers meet on a bustling city bus, their eyes locked, a silent understanding passing between them. One is a strapping lad with an uncut cock tenting his jeans, the other a smooth, eager bottom. They slip into the back, away from prying eyes, as the bus lurches forward. The top unzips, pulling out his substantial length, and begins to piss, the stream arcing onto the floor. The bottom, entranced, drops to his knees, licking the urine from the floor before taking the still-hard cock into his mouth. They switch places, the bottom now pissing, the top hungrily lapping it up before fingering the piss-soaked hole, readying it for his uncut dick.
