A trembling slave, under the watchful gaze of his femdom mistress, follows her every instruction. She orders him to pleasure himself, his hand moving frantically over his throbbing cock. As he nears climax, she barks, "Stop!" His body convulses, but he holds back. She makes him lean down, licking her heels clean, the taste of her leather boots mingling with his pre-cum. Finally, she permits him to cum, but only into a glass. With a mix of disgust and arousal, he downs every last drop, pleasing his mistress and reinforcing his submissive role.
