Mistress Jenny was bored and since she did not have much to do, she felt that it was a great way to spend her time if she mind fucked this guy and dominated him for fun. The mistress did not want anything from him and all she was doing was having fun at his expense. She did not really care what the guy felt as she did not do anything bad to him.
Princess Kate had gotten huge favors from this guy. And she knew he expected to fuck her in return. But she was not ready to do that. So she used her mind fucking prowess to make him believe that they had fucked. She even took videos that she edited to make them suit her narrative. And to make him cum, she jerked him off. He loved that they had fucked although he did not remember much.
