Mistress Mysteria was raised as a spoiled child. She always has someone waiting on her and was very spoiled. Since she had grown, her slaves waited on her. She loves ordering them around and severely punishes them when they disobey her. She had told her slave to clean up the kitchen, but when she went to check the found the kitchen still dirty. She was very mad and called the slave she had instructed to clean to come. She ordered him to lie down and began crushing him with her full weight.
Madam Mysteria felt that facesitting this guy was not enough. She had to do something extra and that is why she chose to facesit him and then farted on him. She wanted the facesitting to be painful and thereafter, together with her farts, to choke him. That is what happened and the poor guy learned never to take her for granted or to assume things when it came to her.
