Step Daughter Dares Me Not To Get Hard

My step-daughter, Gracie, is becoming obsessed with anal sex lately! She wants it from me all the time, and she tries to convince me to have sex on the living room couch this time. She strips for me and then she starts to give me a blowjob again. Then she hops on the couch in the doggystyle position and she shakes her ass for me. She asks me which hole I want to fuck this time! I want to fuck her ass today! After a few minutes in the doggystyle position, she lies down on the couch in the missionary position and I fuck her ass while she is lying on her back. She hops on top of my cock next and she rides my cock with her ass. When I get close to cumming, I have her get down on her knees and I jerk my cock off all over her face. Just like I promised her last time!
