Mistress Samantha wanted to communicate with this guy but he did not respond to her the way she wanted. She was fed up with him and she had to come up with a way to deal with him. The mistress chose to use her shit to do it and it was painful for him as she had him eat her shit as well as drink her pee. It worked out.
Mistress Samantha had a troublesome slave and she had tried her best to talk to him and to have him change but he did not. She was so disappointed in him that she had to teach him a lesson and she did this using her shit. The slave had to eat it for him to know and understand how disappointed she was at him and at how troublesome he was.
