Spoiled and dominant. Thats Princess Serena! No matter if its gifts or money, the princess is used to getting everything she wants and if she doesnt get it immediately, she uses unfair means against you to get it. Just like now! She knows that you cant resist her perfect ass and thats exactly why shes showing it you in short jeans pants now. Princess Serena knows what power her ass has on your compliance and thus makes you completely will-less. You now function according to her rules and Princess Serena gets what she wants. She gets some money out of you, but is that enough for her?
