Mistress Nica does not like to negotiate with people who disrespect her. When this guy did, he had to pay the price and that is why she used her pee to punish him. He was forced to be her human toilet and she also used him as a human ashtray at the same time. He was warned that if he did not cooperate, he would be turned into a shit slave.
Mistress Nica did not like the fact that this guy was too horny. She had to make him realize that he had to get a life and know what there was more to life than sex. So she facesat on him and she had him drink her pee in addition to licking her clit and the soles of her feet. The humiliation made the poor guy rethinking his life choices.
Mistress Nica does not like people who are slow and that is why she had to punish this one. She was pissed at him and she made sure that he would never do any of that nonsense again. So the mistress peed on him and when she was done, she went to her hot tub and she enjoyed herself as he watched and rubbed her feet. He never wanted that again so he changed.
Mistress Nica wanted to show this guy that she was not the sort of person to mess with and then hope to get the chance to do it again. He had pissed her off and she had let it go. But he tried to do it again and this time she did not lt him. She chained him and she peed on him to send a cruel warning to him.
