Lady Demona felt that her rent was too much and she had to find a way to avoid paying it but still live in the same place. She loved the place and she did not want to move out. So she seduced her landlord and since she was hot and naughty, she hypnotized her landlord and made him think she had paid her rent. And that is how she avoided paying rent.
Lady Demona was asked by some girls to teach them about hypnosis and she did it enthusiastically because she is one of the best in the business. The mistress felt that she had to teach them how it was done as a succession strategy. So the mistress gave it her best and trained them to be awesome like her and how to manipulate people using total control and brainwashing them.
Lady Demona did not have anything she wanted from this loser as she hypnotized him. She was just bored and was trying to have fun at his expense. And that is what she did because he could not resist her since she was hot and naughty. The mistress easily hypnotized him and once she had control over him, she had fun manipulating him and playing with him as she wished.
