Mistress Ludovica wanted to take advantage of the fact that this guy had pissed her off to try scat fetish while punishing him. She had always wanted to try it, but she did not have the opportunity. She got the chance now, and she had to make use of it. That is why she turned the guy into a shit slave, and she fed him poo as well as had him drink pee.
This guy had thought that it was his luckiest day. He thought that he was going to have fun with all these mistresses but unknown to him, the mistresses were out to dominate and to have fun at his expense. And it was not the kind of fun he expected and wished for. They wanted to shit on him and they also wanted him to eat their shit so they made him do it.
Mistress Ludovica had to punish this guy and she did it because he was deceitful. She had to stop that deceit and she did it with her shit. She forced him to endure the pain and humiliation of eating her shit and drinking her pee. The guy never wanted to feel that again or to go through that again so he changed his ways like she wanted him to do.
Mistress Ludovica needed to make sure that she taught this guy a lesson but she did not know what to do. She was not sure as she had many ideas but she had not narrowed down to one. She sat down and thought about it then settled on trying scat femdom on him. The scat fetish turned out to be more fun than she had ever thought it could be.
Mistress Ludovica did not like the means this guy was employing to try and beat her in business. She did not mind a clean fight and competition but if he was going to play dirty, then she was the queen of dirty. That is why she chose to use her shit to do it. The mistress made sure that he ate her shit and that he drank her pee before she was done with him.
