The mistress's voice is a whip, sharp and commanding, as she orders her sub to pleasure himself. He tentatively grips his throbbing cock, eyes locked on her, seeking approval. She sneers, "Faster," and he obeys, his strokes becoming frantic. She leans in, her breath hot on his ear, "You like this, don't you? Being used, being humiliated?" He moans, lost in the degrading pleasure, his body betraying his mind as he hurtles towards orgasm, only to be cruelly stopped by her cruel, delightful command.
