When this guy backstabbed mistress Iside, he did not believe that she would find out but she did. And when she did, she also did something he never expected which was to turn him into a human toilet. He was forced to eat her shit and to drink her pee. It was cruel and brutal for him but he had no choice other than to eat the shit as directed.
This guy was too nosy for mistress Iside and she chose to deal with him by trampling and dominating him. The mistress went ahead to dominate him with her shit and made him eat it and then wash it down with her poo. And that is how the mistress made the guy stop being nosy as he felt it did not pay but rather brought him a lot of misery.
