Lady Phoenix had an issue with the way this guy handled her assignemts. She felt that he had to be tamed and punished so that he did not repeat his mistake. So she went out of her way to facesit on him. But that was not enough. She farted on him and made sure he nearly choked before she felt it was enough. He promised her he would never repeat his mistake.
Lady Phoenix is a BBW mistress and she was being bothered by this guy who kept making comments about her weight. She wanted to shut him up and she did so using her farts. She farted on him and forced him to smell her farts. And she had the help of her BBW friend who also did the same to him. He never made any comments about them ever again.
