Goddess Nemesis had tried to guide her junior the best way she knew how but it was becoming difficult and hard for her because she did not feel like he was listening or following her instructions. The mistress had to dominate him and she did so using her femdom toilet. The guy had no choice but to eat her poo and drink her pee before she was done with him.
Goddess Nemesis wanted to facesit this guy and that is why she had to do what she did to him. The mistress chose to use her femdom toilet to degrade as well as torture him and that is exactly what she did to him. The mistress had to make sure he knew how to eat poo and by the time she was done with him he had learned to eat shit like a pro.
This guy was too idle for this mistress and she wanted to ensure that he learned to let go and to do things the way he needed to do them. That is why the mistress had to make sure that she humiliated him so that he would learn from his mistake. He learned after the mistress invited her friend over and the two of them made him a human toilet.
