This mistress was not about to deal with an uncouth slave. She had to punish him and she used her big ass to do it. She smothered him with her big ass and she forced him to lick and smell her ass after she was done smother him and facesitting him. It was painful and humiliating but he deserved it and he promised her that he would stop his uncouth behavior.
This mistress is blessed with a big ass and she knows how to use it for whatever she wants. But today she did not want anything from anyone. All that she wanted was to humiliate this guy because he had pissed her off. So she taught him a lesson by using it to smother him and degrade him like never before. He cried but she was not moved by any of his tears.
