My identical step-sister who normally helps my step-dad with his porn business (and fucks him regularly) is out of town for the weekend. I got the chance to help him, and got to see the sexy model he was working with get fucked. Their shoot gets interrupted and so I decide to give him his step-father's day gift -- ME. It's my first time ever with a man, and his thick dick nearly breaks me, and gives me a massive load in my face. In the end I think I'm definitely the new favorite step-daughter. I think dick is definitely for me.
