Mistress Fan wanted to rehabilitate this guy so she gave him a job in her house. But it was not easy for him to stop his thieving ways so she had to make him stop and she did it with her high heel trampling and she topped it off with her shit fetish. He had to eat her shit and wash it down with her pee and that changed him.
Goddess Wu had had a talk with this guy and she knew that he would back her up when the issue came up before the board. But he did not and she was left to defend herself alone. She managed to do it and she evaded sanctions. But she had to make sure the guy would never do what he had done again. And she did so by shitting on him and making sure he ate all of her shit.
Mistress Zhan laughed at her boyfriend as she dominated and humiliated him. He had pissed her off and she did not want him anymore. She had tried her best to put up with him but she had reached a breaking point and so she shit on him then chased him away. He was shocked at the turn of events but she did not care about what he felt or what he did.
Mistress Rin and mistress Yan wanted to show this loser that he did not have any power in their house. He was just a slave who needed to follow orders and do as he was instructed. He had tried to take some power but they did not allow it. Instead, the mistresses forced him to eat their shit and warn him of worse consequences if he ever did it again.
