Mistress Iside had an annoying slave, and she felt that she had to dominate him and teach him a lesson. It had to be a lesson that no one had ever taught him before so she turned him into a human toilet, and she forced him to eat her poo. She was sure that he would sit up and take notice and change like she expected him to, after he ate her poo.
When this guy backstabbed mistress Iside, he did not believe that she would find out but she did. And when she did, she also did something he never expected which was to turn him into a human toilet. He was forced to eat her shit and to drink her pee. It was cruel and brutal for him but he had no choice other than to eat the shit as directed.
