Mistress Roberta had broken up with her boyfriend and now that they were exes, he thought that she was still the same girl he knew. He tried to use her and to blackmail her but he realized the ground had shifted when she used her shit to scare him and tell him that the next time he tried any nonsense on her, she would make him eat her shit and swallow it.
Mistress Roberta found out about shit fetish and she knew she had found the best way to punish anyone who messed with her. She had an easier time with her slave and anytime he messed up, all she had to do was to shit on him. He dreaded it and was degraded by it so he tried his best to make sure he did not piss her off so as not to be shit on.
Mistress Roberta had had an expensive meal and her slave was feeling bad that he had not been invited to the dinner. She decided to share with him the meal she had had but she had to do it in a very different manner. She shit on a plate and she forced him to eat it. The slave tried to refuse but the mistress would have none of it. He ate it.
