AmateurMates presents Biflatmate, a bisexual gay stud with a fetish for water sports. Stuck at his desk, his white skin flushes as he feels his bladder about to burst. He sheds his clothes, revealing his circumcised, fat cock, and begins to relieve himself into a bottle. His roommate captures the intimate moment, with Biflatmate's gay encouragement filling the room. His feet, clad in sandals, shift uncomfortably as he empties himself, his pale skin glistening with sweat.
