A wife's fetish-driven command turns her husband into a willing cuckold, his humiliation a aphrodisiac. He watches, helpless, as she's taken by a massive, black cock, his own inactivity a cruel, exciting contrast. She uses him, making him service her, licking her soles, as she's filled, her moans of pleasure a stark reminder of his lack. In the end, she forces him to drink the bull's cum, her dominance complete, his subservience absolute.
