Mistress Jenny had a lot of debts. And she also had the ability to pay them but she was not good at that. She was lazy when it came to servicing her debts and she was nearly auctioned as a result. When she realized things were that bad, she chose to use findom fetish to get herself out of the mess. So she turned a few guys into her human credit cards and serviced her debts.
Mistress Jenny had a massive project to carry out. She wanted a good amount of money to carry it out and she did it using the money she got from this loser. She financially dominated him and she made sure she got all she could from him. She then went to a different loser and she got more money from him. She combined all the money she had gotten from all the slaves and that is how she financially dominated them and financed her project.
