In a clinical setting, a dominant woman commands her submissive partner to dress in riding gear and assume a horse-like stance. She wields a riding crop, striking his thighs and ass, leaving red welts. He groans, his cock straining against his jodhpurs. She orders him to piss, and he releases a stream onto the floor. She makes him lick it up, then forces him to his knees, unzipping her pants to reveal her bare pussy. She smears his piss onto her clit, rubbing it in as he watches, helpless and aroused. She then shoves his face into her crotch, making him lick and taste his own piss mixed with her arousal.
