Two anonymous men, unseen faces obscured by shadows, meet in a seedy bathroom. The taller, beefier one pins his partner against the grimy wall, his massive cock already throbbing with anticipation. He spits in his hand, lubing up his bare dick, and pushes his partner's legs apart. With a grunt, he buries himself deep in the other man's ass, fucking him hard and fast. The bottom moans, his own cock twitching as he's pounded, begging for more. The top, enraged with lust, grabs a bottle of piss from the floor and splashes it onto his partner's back, using the liquid to slick up his ass even more. He fucks the piss right out of him, the room filling with the sounds of their wet, slapping flesh and the bottom's desperate cries.
