Gaywolf, the renowned pup trainer, pushes Mastino's limits in this intense BDSM session. Bound in leather, Mastino's exposed body shivers as Gaywolf drizzles warm urine over his skin, the scent of ammonia filling the air. Mastino's petplay role is evident as he laps up the golden liquid, his body writhing in a mix of pleasure and humiliation. The session intensifies as Gaywolf uses a catheter, filling Mastino's bladder before releasing the warm stream, testing his puppy's control.
