In the dimly lit bathroom, a man enters, his eyes scanning the room until they land on the toilet. He's not here for the typical reasons; he's here for the thrill. The cool tiles against his skin and the distant hum of the city outside create a unique, tingling sensation. He unzips, his pants falling to the floor, and takes a seat. The cold ceramic against his ass sends a shiver up his spine as he begins to stroke, his breath quickening with each passing moment.
