In the sterile, clinical setting, Nurse Domina commands her slave, "Bitch, you're mine to use." She straps on a colossal, veined dildo, her eyes gleaming with dominance. The slave, bound and gagged, trembles in anticipation. The nurse runs the dildo along her slave's lips, forcing him to worship it. She then positions him on all fours, slapping his ass before plunging the strapon deep inside him, pegging him with fierce, relentless strokes. The slave's muffled moans fill the room as his mistress trains him, using him for her pleasure.
