Cosmo finds himself in a world of pain and humiliation as Yara Frei, his merciless mistress, turns him into her human toilet. Bound tightly in bondage, Cosmo's body is a canvas for Yara's pleasure. She sits on his face, her pussy grinding against his nose and mouth, forcing him to inhale her scent and taste her juices. Cosmo's struggles only earn him a taste of Yara's piss, as she trains him to be her perfect, obedient toilet slave, ready to serve her every need.
