Mistress April, clad in latex, dominates her ebony slave Rosie in an intense gym BDSM session. Rosie, bound and helpless, is subjected to a rigorous workout, her big tits bouncing as she's made to perform strenuous exercises. April teases Rosie's pussy with a dildo before pegging her, stretching her tight asshole. Rosie moans in pleasure-pain, her body glistening with sweat as she's caned and beaten, her slave training culminating in a humiliating anal fucking.
