When it comes to torturing people who piss her off, this mistress is probably one of the best out there. She wanted to torture and to humiliate this guy and she did it with her big ass as well as with her shit. She fed him her poo and laughed at him as he did her thing and she did not need to warn him as she knew he would never do it again.
When this mistress got fed up with how her boyfriend acted, she knew it was time to stop being understanding and to take action against him. That was the only way she was going to change him and she made sure that she got what she wanted out of him by shitting on him. Once he was turned into a human toilet, he did not have the strength to continue being a disappointment.
