Lady Karame likes to give to charity and she likes the glory that comes with it. But she also knows that it is not easy making good money in order to have enough left to give away. And that is why she chose to use her money slave fetish to do it. She financially dominated her slaves and she used part of that money to give to charity. And that is how she never felt bad about her findom fetish.
Lady Karame found out that this guy was interested in her and she knew she had found herself another pay slave. So she put on her charm and she got him recruited as one of her human credit cards. She dedicated some time to getting to knowing him and to charming because she knew all that information would come in handy later on when she needed him to pay her.
