Mistress Kim needed to scare the shit out of this guy and that is exactly what she did. She ensured that the guy learned his lesson and that he did things her way. That is why she opted to trample and make him lick her feet. He was scared at what she did to him and he learned to avoid her because he did not want to piss her off.
Goddess Yasemin used her sexy feet and thighs to tease her slave. She did not want to fuck him but rather, she was getting him turned on so that she could teach him how to jerk off like a pro. She had him follow her instructions and she had a great time and one of the best climaxes he had ever had. He now knew how to do it whenever he was horny.
