In a public toilet stall, Yara Frei, the ultimate humiliatrix, trains her eager piss-drinker. She struts in, heels clicking, commanding her sub to follow. He watches, entranced, as she hikes up her skirt, revealing her bare, perfect ass. She orders him to worship it, grinding against his face until he's a desperate, drooling mess. Then, with a wicked smile, she sits, filling the toilet with her piss. He eagerly laps it up, his humiliation complete, his devotion to Yara absolute.
