This mistress knew that this guy troublesome and would not agree to do what she wanted unless she made him do it. So she did not hesitate to trample his face as painfully as she could with her bare feet. And when she was done, she made him drink her pee. The pain she had inflicted on him made him agree to do what she asked him despite how cruel and humiliating it was.
Mistress BlackDiamoond was horny and she found herself masturbating in the livingroom. She even used a dildo and when she realized her slave was watching her, she was pissed and she had to punish him. She used an improvised funnel to pee into his mouth and she forced him to lick it. She made sure that by the time she was done with him, he had drunk several liters of pee.
