Princess Deh paid her slave well. And since he knew how to save money, he had more money than she did today as she was broke and had spent all the money she had. The money she was waiting for had not yet come and she needed some money to last her a few days. So the sly mistress financially dominated her slave and she made some money from him.
Mistress Isabella had done a lot for her ex. She had spent a lot of money on him when he was broke. But when he got a good job, he dumped her. She accepted it but before she was done with him fully, she financially dominated him and she got some of what she had spent on him. She knew him well so it was easy to lure him for her plan.
