Bound and helpless, the slave is made to worship his mistress's ass, licking and kissing it until she commands him to eat it. He buries his face in her crack, his tongue probing her hole as she grinds against him. She then pisses all over his face, making him drink every drop. Once she's satisfied, she moves onto his ass, stuffing it with her strapon, pounding him mercilessly. She pulls him up, his ass leaking her cum, and makes him kiss her, tasting his own degradation on her lips. She laughs, "You're my piss-drinking, ass-eating slave now."
