Lady Dominika had supported her boyfriend with his hustle and when he made money, he acted like he had done it all by himself. She did not like that very much and she had to put him in his place. This was done by shitting on him and it was gross as he had to eat her shit as well as lick her ass clean. He was brought down to earth with that action.
Lady Dominika wanted to scare this guy and she did it with her poo. She had to make sure that she succeeded in what she did and that is why she settled on poo since she was sure that he had never experienced that before. He was scared of her when he realized that that was what she was planning to do. He never expected that but he could not do anything about it.
Lady Dominika wanted this guy to learn that he could not go around making fun of people and hope to get away with it. She was hurt by a joke he made about her body and she waited until she had cornered him to make sure that she punished him. The mistress went and took a shit then went to him and had him lick her asshole clean. He was her human toilet.
