When this mistress realized that she needed to dominate this guy, she did it with her hypnosis fetish. The mistress had to make sure that she had teased him and gotten control over him so that she could do what she wanted to him. She was sure he was powerless over her and that is why she did what she did to him. And she managed to achieve all she wanted to.
This mistress did not want to go through the whole process of applying for a raise and having to justify it when she could just hypnotize her boss and have it in a second. And that is what she did after she had found out her boss liked to secretly check out her ass. She teased him with her ass, her pussy and her tits and she got what she wanted without having to give up the cookie.
