Mistress Venus did not want to spend a lot of time convincing her pay slave to give her money. She did not want to also turn him on and do naughty things for him. So she hypnotized him to get her way. She wore her naughty lingerie and she teased him and she got him hypnotized and then she took total control of him and used that chance to financially dominate him.
Lady Vivian wanted to test whether her tits could be used for hypnosis and whether she could also financially dominate with them. She got a guy who had not had sex in ages so he was easily aroused. She played with her tits and she used them to turn him on. She financially dominated him without him even knowing that she was doing it. She made him cum but she also got good money out of it.
