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.
Mistress Akemy and her friend mistress Scarlet wanted to teach this guy never to mess with them and that is why they chose to use their asses as well as their farts to do it. They went ahead to force him to lie down and lick their asses including their assholes. And then he had to smell their farts. It was degrading but he had no choice or say in the matter.
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.
