This mistress wanted to turn her slave into a human toilet paper and she did it by forcing him to lick her asshole clean. She had made him eat her shit and when he was done, he thought the ordeal was over. But he was mistaken as she made him lick her asshole clean and he was only allowed to go when she inspected her anus and found out it was as clean as she wanted.
When this mistress was told that this guy was behind her woes, she could not wait to teach him a lesson. She lured him to her house where she turned him into a human toilet. She had fun making him eat her shit and she had him do nasty things for her. She even took a video of it as evidence to blackmail him later on because she was not yet done with him.
This mistress was horrified to learn that her slave had been recording her taking a shower. She was pissed that he had a pervert in the house and she had to deal with him accordingly. She used her shit to send a message to him that it had to stop and he had to hand over all the footage he had to her. He did so after eating her poo.
