I have just finished school and I am relaxing on the sofa reading my book, I ask you nicely if I can go to a party this weekend. The answer is no, so i decide to take matters into my own hands. I sit back on the sofa and let you my short school skirt lift up, revealing I am not wearing any panties. I can see you getting hard at the sight of my tight shaved pussy, so I decide to make you a deal. I show off my pussy and play in front of you while you wank your cock, and I can go to the party. Of course you can't say no, what a dirty pervert you are, wanking over your own stepdaughter!
