Madame Ellen needed to find a way to deal with this guy and she did it in a way no one expected her to do. The mistress cruelly forced the guy to become her human toilet. He had no say in the matter and all he was required to do was to follow her instructions. He was powerless to do anything about it. He just had to eat her shit and drink her pee.
Madame Ellen came home and found that her slave had not prepared lunch. He was busy watching movies and relaxing when he knew he had some responsibilities and chores he had not yet done. She was so pissed that she took a shit on a plate and she fed it to him. That was how he knew never to fail in his duties as she would not let him get away with it.
Madame Ellen does not like to physically hurt people. That is why she did not whip or trample her slave when he misbehaved. She had to come up with a way to punish and dominate him. And she did so using her scat fetish. He was turned into a toilet slave and he had to eat her shit. She used an improvised toilet seat to do that to the slave.
This guy disobeyed madame Ellen and he was shocked at what she did to him. The mistress used her shit to punish him. He was made to first of all jerk off without any stimulation and without any lube before she made him her human toilet and she forced him to eat her shit and drink her pee. He tried to beg for mercy but none was shown to him.
