Mistress Evgenia found this guy to be gullible and she knew that she could easily make him a paypig. So she turned him into a findom slave by teasing him a bit and controlling him. She used her sexiness and naughtiness on him. And since he was not used to having such hot women with him, it was easy for her to turn him into a financial slave and dominate him financially.
Mistress Evgenia and mistress Sandra did not know this guy but that did not stop them from humiliating him for their own fun. The mistresses did not care what the guy felt. All they had to do was to trample and dominate him and they did it with their feet. They noticed he was gullible and they told him he would be free to go if he bought his freedom. He did.
