Mistress Maryan wanted to degrade this guy and she did it in a way she knew would take him by surprise. She turned the guy into a human toilet and she forced him to eat her poo as well as to drink her pee. The guy never wanted to do anything like that, but he was not given an alternative. He had to eat it from the floor after she was done shitting.
This guy talked too much and mistress Maryan was fed up with him. She wanted to find a way to deal with him and that is when she chose to dominate and humiliate him like he had never been before. The mistress cruelly used her shit to degrade him by making him eat her poo so that he would learn to shut up and not talk too much. He never did it again.
Mistress Maryan wanted to try scat fetish and she knew this guy wanted to have sex with her. So she told him she would do it only if he agreed to eat her shit. The guy thought long and hard and he agreed to do it. He ate her shit and when he was done, he fucked her like she had never been fucked before. They each got what they wanted.
