Mistress Katherine had nothing to do with this slave as she felt that he was too careless for her. She had to make sure that things changed and that he learned to do things better than he had been doing them. She chose to use her femdom toilet to degrade and humiliate him before she let him go. He thought he was dreaming but he was not and he had to eat poo.
Mistress Katherine likes to be feared and that is why she had to do what she did to this slave. She had him lick her shit and lick her asshole as well. She wanted him to know that she would do it again and that she would do even worse things to him. That is how he learned that she was not one to mess with and he changed his ways.
Mistress Katherine wanted her boyfriend to learn that he could not just lie in bed all day and wait for her to bring him food as he watched movies and played video games. She wanted him to help her and when he did not, she had to punish him and she did so with her shit. He had to eat her poo and drink her pee before she was done.
Mistress Katherine had watched people get their asses and their assholes licked and she wanted to get that experience. She did not have anyone to do that to her and she chose to pay someone to do it for her. She got this guy who agreed and he got down to business and she loved everything he did and how it felt. He had her ass licked so good that she had an orgasm.
