Mistress Dula wanted to make sure that this guy learned not to mess up and inconvenience her the way he had done. So she invited her friend to help her punish him and the two of them had a great time doing it. They had him eat shit as well as drink pee and he did not have a say in the matter. He only had to do what he was told.
Mistress Dula does not like to be ignored and when this guy ignored her, she had to punish him for it. She did this with her human toilet fetish and she dominated him in a way he had never felt before. It was brutal and cruel as he ate her shit and she kicked him in the nuts as she had him eat her poo. He could not believe it.
Mistress Dula did not want to let this loser waste any of her time. She felt that it was important to show him what she was willing to do to anyone who pissed her off. That is why she chose to use her human toilet fetish to deal with him. He was turned into a human toilet and he had o eat her poo and drink her pee. It worked.
