In a dimly lit room, a man kneels, his hands bound behind his back, eyes downcast. His mistress, clad in leather, circles him like a predator. She commands, "Prove yourself." He nods, lips sealed tight. She starts with a hard slap across his face, then moves to his chest, leaving red handprints. She orders him to crawl, which he does, humiliated yet aroused. She sits on a chair, spreading her legs, "Lick." He complies, his tongue flicking out, tasting her, earning another command, "Harder." He obeys, his devotion to her dominance absolute.
