Follows on slightly from "Need to be bred", no doggy dildo in this video, but reference to Rex. I sneak into my step brother's room, its that time of the month again and I am so horny. I see his big morning wood under the blanket. I open my legs and show him the big creampie that rex just gave me, but I am still not satisfied, I suck my step brother's big hard morning wood while he lays in bed. I then get on top of him and ride his big hard cock, showing him a new position we haven't done before. I then lay back and let him fuck me missionary until he gives me a nice big creampie! My step brother is such a good learner :P
