A smile playing on his face, as he could feel his slow teasing thrusts getting their desired from his secret mystery partner.  As he could feel her pushing back towards him, wanting to be fucked more and harder.  Thinking to himself, who was he to deny this little double brother fucked sexy smooth skinned girl what she was craving right now.  So taking a firm grip of her hips, he pulled back so his cock nearly slipped right out of her.  Before driving in deep and hard.  Feeling her tight wet pussy taking his big hard cock.  Driving in again, over and over again.  Letting out a small animal like grunt from the effort as he fucked her hard.
