The stern mistress, clad in latex and lace, towers over her cowering slave. "Surrender to my will," she demands, her voice dripping with authority. She runs a gloved finger along his quivering lip, causing him to tremble. She seizes his hair, forcing his head back, and begins her lesson. She clamps his nipples, twisting them cruelly, making him gasp. She orders him to her feet, his hands bound behind his back, and attaches a weighted chain to his balls, causing him to wince. She parades him around, his humiliation complete, before subjecting him to a relentless session of electric shocks, his screams of pain music to her ears. She relishes his suffering, her own arousal growing with each of his cries.
