ステップパパの背中を引っ掻いて、ステップママに言わないでください

I am a girl asking my step-daddy if I can go out, he says yes but ask me to scratch his back first. He likes it and it makes him horny, he starts jerking his cock, I am shocked to see his big cock. He wants to cum and asks to see my ass then he wants to put it in my tight pussy, under slight protest he fucks me stands up from behind, and shoots his load on my pussy, I want to see it and taste it, then he has me clean his cock with my mouth. Then he let me stay out later than I am supposed to and we agree not to tell StepMom.
