A femdom mistress delights in cuckolding her submissive partner, training him to serve her every need while she's thoroughly fucked by a powerful, hung stud. She parades her lover's replacement in front of him, making him worship his replacement's cock before making him watch, powerless, as she's pounded from behind, her body shaking with pleasure. The cuckold's humiliation is complete as he's forced to clean the bull's cum from his mistress's used pussy.
