Madame Ellen understood how hard the parents of this student worked hard to put him through college and she did not like how and why he was taking his studies for granted. So she had to get to him and make him change course. So she used her shit to do it and the student had to eat her shit as well as drink her pee. He had no choice but to do it all.
Madame Ellen learned that her slave was forgetful and she knew that she had to do something about it. She had tried to give him a chance to prove her wrong but he did not. So she turned him into a human toilet and she forced him to eat her shit as well as drink her pee. And when she was done, the mistress knew he would never forget anything.
Madame Ellen wanted to shit on this loser and she did it in a way that he did not expect. The mistress made sure that she ate her shit and drank her pee. He was humiliated and he was degraded but he was too scared to do anything as she was worried about what he was willing to do to him if he refused to do what she asked him.
Madame Ellen felt that her slave was being insubordinate and she was not going to allow it. She had to stamp out that bad behavior and nip it in the bud before it grew. So she used her scat and piss fetish to do it. He was turned into a human toilet and had to eat her shit and drink her urine before she let him go. He never messed again.
Madame Ellen did not like how her lawyer handled her case. She felt that he had to do it a little bit better than he had been doing. So she used her shit and piss to punish him. She knew it was cruel, humiliating, and downright degrading but that is what she wanted and that is what drew her to it. So she made sure he was her human toilet.
Madame Ellen gave her slave an assignment but she did not give him any room for error. She wanted him to do the assignment perfectly and when he did not, she had no choice but to punish him. She made it a humiliating affair as she had him lick her toes first and then she got him to drink her pee and finally to eat her shit. It was degrading but he deserved it.
Madame Ellen was not amused with how she was treated by this loser and she had to make sure everything changed. The mistress used her shit as well as her pee to make sure he changed. She did not want him to do that again and he had no choice but to do things her way. The mistress watched as the guy got degraded and defeated until he gave in.
