Mistress Nemezis had tried to look away as this guy annoyed the crap out of her and others. The guy was given hints that he was annoying but he seemed to enjoy the effect he had on other people. The mistress did not like that very much and she felt that she had to do something since no one else seemed to do it. So she took him aside and she made him eat shit.
When this guy chose to do things that this mistress did not agree with, he did not know that he had brought a lot of problems to himself. He was smothered with her ass but that was not all. The mistress also forced him to eat her shit as well as drink her urine. Before he was done and was allowed to leave, he was made to lick her asshole.
This mistress had a new associate but he was indecisive and she did not like that about him. He was not a good fit for his role on account of that but he had already gotten that position and she wanted to give him another chance instead of firing him. So she scared him with poo which he had to eat for him to get out of his indecisiveness and do things as well as she expected.
Mistress Nemezis was shocked that her contractor had gone rogue. He was doing things she did not ask him to do and he was also taking shortcuts. He was taking advantage of the fact that she was busy and could not be there to supervise everything he did. She was so pissed that she had to punish him and make him redo all the work he had done. So she pooped on him and had him eat it all.
This slave was too loud for this mistress and she had to do something to him. She sat down and thought about it and she settled on shitting on him. The mistress did not want to dwell on the same issue for a lot of time and she wanted a punishment that would do the trick once and for all. That is why she settled on scat femdom and she used it to make him learn not to be loud.
