This mistress likes to have a slave who cooperates. This slave was uncooperative and she did not like that. She tried to talk to him to see if he would change but he did not and that pissed her off as he did not seem to know his place. So she forcefully made him know his place. The mistress made him eat her poo and when he was done, he became cooperative.
