Mistress, adorned in black latex, teases her submissive with a sleek, pink vibrator. She traces its buzzing tip along his trembling thighs, pausing at his throbbing erection. "Beg for it," she commands, as he whimpers, desperate for her to touch him. She obliges, running the vibrator along his length, making him squirm and moan. His pleasure is hers to control, and she revels in every shudder.
