Stepdaughter shows pretty tits and ass and started rubbing daddy's cock

My mom has been such a bitch lately. I'm 18 and she gave me a curfew! What the hell? So I went to my step-dad who has a ton of money and is constantly getting boners when I walk around the house. I've always thought he was kind of hot. I knew I could get him to give me money for my own apartment if I was a good girl and gave him exactly what he wanted, to finally be the slutty little girl he thinks about when he jerks off next to my bitch mom at night.
It wasn't hard to strike up the deal. I told him I wanted to move out, showed him my pretty tits and ass and started rubbing his cock through his pants. He was instantly hard. I straddled him stroking his fat dick, took off my shirt and showed him my ass. Then sat down right on top of him and stroked his cock like a good baby girl until he came the biggest load in my pretty little hands. I got my apartment he got to cum. It was a really win-win situation.
