Mistress Evgenia and mistress Sandra are close. That is why mistress Evgenia went out of her way to teach her friend how to make money when she got in debt and she was in a bad place financially. The mistress had a loser who she dominated financially so as to show her friend how to do it. And given how mistress Sandra was hot, mistress Evgenia knew she would not have a hard time getting pay slaves.
Mistress Evgenia wanted her friend to learn how to dominate paypigs so she showed her friend practically. As the paypig licked her soles and he did what the mistress asked him to do, her friend learned on what to do and had some of her own ideas of what to make him do and she had him do it when her turn to dominate him came. She became a pro in a short period of time.
This guy brokered a deal mistress Evgenia was involved in but he did not want to give her the cut that she wanted and that she deserved. So she knew it was up to her to get what was due to her. So she used her findom fetish to get it. The mistress stripped him naked and dominated him before she made him give her what she deserved to get.
