When this mistress realized that she was dealing with a gullible guy, she knew that the best cause of action was to make the guy her money slave. She wanted to dominate him financially and since he looked loaded, she did not hesitate to do so. The mistress teased him with her hot and sexy body and he was turned on and hooked on her like she had predicted he would.
Once this mistress had dominated this guy financially, she thought it would be good for her to entertainment him a little so as to soften the financial blow he had taken from her. And that is why she wore her bikini and she used it to show off her body and to make him want her and to basically entertain her for about an hour before she let him go.
This mistress needed to better her life and she chose to do it by investing. However, the money she was investing was not really hers. She got it from her money slave and she used financial slavery to get the money to invest. She built a good portfolio over time as she continued to have fun with her money slaves who found her irresistible and tried to please her in any way they could.
