The submissive's eyes dart nervously between his mistress's stern gaze and his throbbing cock. She demands he stroke faster, harder, until he's on the brink of orgasm. "Cum in your own mouth," she orders, her voice cold and commanding. The submissive, trembling, tries to aim his cock at his open mouth, but his hands are shaking too much. His mistress tuts in disapproval, pushing his head down with her foot, forcing his face closer to his cock. "Again," she commands, as he struggles to comply with her humiliating, yet thrilling, orders.
