This guy tried to bully this mistress but he realized that he had messed with the wrong lady as she was not going to let him try to bully her. She also knew he bullied others and she did not want that to be a thing. So she ball kicked him hard so that he stopped being a bully altogether. It worked and he never bullied anyone else again after that.
This student was a nuisance to this mistress and she did not want to keep entertaining him. So she went out of her way to punish him by ballbusting him since she was fed up with his behavior and she felt he had to change. He wished he had not messed with her but it was too late and he had to face the music. The painful punishment did its work and reformed him.
This mistress had been lied to by this mistress so many times that she felt it was a habit that needed to be broken. And she did not want to sit back and expect someone else to take care of it for her. So she took care of it herself by ball torturing the guy. She wanted the pain to get to him and teach him never to lie again.
