In a dimly lit, opulent dungeon, a woman of power and poise, known only as Mistress, commands her submissive to stand before her. She, clad in leather and lace, orders him to stroke his cock while she watches, her eyes gleaming with sadistic pleasure. As his breathing grows ragged, she commands him to open his mouth, her tone brooking no argument. He obeys, and she guides his cock to his own lips, ordering him to cum, to "fill his own mouth with his worthless seed." He hesitates, but her stern gaze pushes him on, and he does as told, cum filling his mouth. She then commands him to swallow, her voice laced with satisfaction as he complies.
