The room is filled with the sound of running water and the scent of urine, a heady mix that only serves to heighten the solo performer's arousal. He's already coated in his own piss, his body slick and shiny, his cock standing at attention. With a groan, he begins to stroke himself, his hand moving up and down his shaft in a steady rhythm. The sound of his hand on his cock fills the room, a symphony of pleasure that only he can hear. His body tenses, his breath coming in short gasps, and then, with a final cry, he comes, his cum mixing with the piss already coating his body, a testament to his solo indulgence.
