This mistress needed to be fucked properly and she did not get that from this guy. That is why she went out of her way to dominate him and humiliate him for what he did. She did not want to continue demanding that from him. What she did is to punish him for not doing it and she used her facesitting fetish to do it. He was humiliated and he cried as she did it.
This mistress knew she had to teach this loser a lesson and she did it with her facesitting. But she felt that facesitting was not enough for him and she did something else. She went ahead and she used her feet to ballbust him and that was when she felt that he had gotten the punishment that he deserved and she let him go. He never messed with her after that.
