Avery Cristie Leaks

I'm on a road trip with my superhot stepsister Avery. I always noticed how pretty she was and she's always had a perfect body, but I never really thought about it. Or maybe I kept the thoughts in the back of my head. When she comes out of the bathroom in a loose shirt and red panties I know it is going to be a long night. I try to just rest but I can't. Then she roles over and her foot brushes right up against my hardon. Fuck, I don't know what gives me the balls to do it, but I reach over to her and she opens her eyes staring right at me...
