This mistress has a big ass and she loves to use it to dominate as well as humiliate. That is why she had to dominate him and do it in a way that he had never experienced before. The mistress went out of her way to teach the guy never to mess with her and he got the message as he choked under her facesitting and her stinky and smelly farts.
When this mistress noticed that she was dealing with a compulsive liar, she had to dominate him and she did this with her farting femdom. She chose to turn the guy into a fart slave and to force him to not only smell her farts, but to also endure her facesitting as well as lick her ass while at it. It was humiliating but the guy knew that he had to do it.
When it comes to wanting to have her way, this mistress is one of the best. She loves to dominate people and to make them do what she wants. She wanted concurrence with him on a certain matter and since she was not getting it, she felt that she had to force him to do it. She did so using her farts and she got what she wanted at the end of the day.
This slave was perpetually late and this mistress did not want to keep forgiving him as he did not look like he wanted to change. So she had no option other than punishing him and she used her farts to do it. That was to be a warning to him that she would not tolerate his behavior and if he messed up again, she would do something worse and he would only have himself to blame.
