Mistress Wu loves to humiliate and to make adults cry. This girl had messed with her and it was time to make her learn that she was not to mess with. She had given her a warning but she had ignored it and she knew that she was not to blame. He had to blame himself for what she was about to do to him which was to facesit on her and lick her asshole clean.
Mistress Wu was owed money by this girl and she wanted it back. She did not want to let her get away with not paying her. She had given her more than enough time to pay her back but she was trying to dodge her instead of paying her or being straightforward with her. So she facesat on her and she forced her to eat her ass, lick her asshole as well as smell her farts.
