Princess Serena did not like how her ex was bothering her but then she realized that he could be useful to her financially so she turned him into a financial slave. She did not do any of the things she did with him prior to breaking up with him but he had a new role in her life to be her human atm. The only thing he enjoyed was being teased and denied.
Princess Serena was concerned about how low her bank balance had gotten and she wanted to do something about it. The mistress felt that she needed to make sure that she had more money in her account for the many things she wanted to do. So she went to her paypigs and she unleashed her charm like they had never seen before and then she laughed all the way to the bank.
