Steam billows from the grimy bathroom floor, a symphony of dripping faucets and echoing coughs creating a cacophony of sound. Our pervert slips into an empty stall, the door barely latching behind him. His breath hitches as he pulls out his throbbing cock, already slick with anticipation. He spits into his palm, the sound of his hand working his shaft echoing in the small space. The scent of piss and soap fills his nostrils, heightening his arousal. He can hear the muffled voices outside, oblivious to his filthy act. He's on the edge, ready to release, when the door creaks open, revealing a shocked onlooker. He grins, inviting them to join his disgusting delight.
