Goddess Saffron had borrowed some money from this guy. When it was due for payment, she turned him into her human credit card using her findom fetish and she was able to get money from him which she used to pay him back. In essence, he had paid himself back but she did not look at it that way since she had expended time and effort to get the money from him.
Goddess Saffron does not like stingy guys and this guy was one. He was trying to seduce her but when she realized he was stingy, she had to do something about it and she settled on dominating him financially because that was what he would feel the most. So she made him her financial slave and he cried and begged her not to do it but she did not listen to him.
