This guy was too nosy and these mistresses felt that they had to dominate and torture him. That is why they chose to use their asses to do it. He was turned into an ass slave and he was forced to endure the facesitting he was subjected to. He cried and begged them for mercy but they ignored him and they went ahead to trample the shit out of him.
Lady Tassia is the kind of person who loves to get even and she does it all the time. Today she felt that she had to torture this guy and make him do the kind of things he had never done before. He had to learn his lesson the hard way and that is why the mistress had to facesit him and also make him smell her stinky farts besides peeing on him and making him drink the pee.
