Mistress Ludovica had been misled by this guy, and she did not like that. She took offense at what he had done, and she knew that she had to find a way to dominate as well as degrade the guy, and she did so. It was not as easy as the guy thought. What she did was to make sure that he ate her shit and that he drank her pee before she let him go.
This mistress felt bad that this slave who she had tried to help was misusing her stuff. She had to show him what she does to people like him and she made sure it was painful and humiliating as well as degrading. The mistress took a shit on the slave and she forced him to eat her poo as well as drink her urine. He never misused her stuff again.
