Mistress Simay did not want an ignorant guy working with her. So she chose to punish the guy so as to make him do something about it. The mistress went out of her way to make the guy eat her shit as well as drink her pee so that he knew how serious she was about the whole thing. And that is how he changed as he knew she would not relent.
Mistress Simay does not like irrational people and when she noticed that this guy was, he had to be punished. She made sure it was the kind of punishment he would never forget in his life and she did so using her shit. He cried and wished he had not pissed her off but it was too late at that point. He had no choice but to do what she wanted.
