Naomi's ass...
Later in the vid, he DOES put it to her ass. And the way she gyrates, I'm surprised she doesn't just rip the guys dick off!
I recommend anything Naomi is in.
However, apparently she has been hittin the gym, and is on some Hollywood diet (starvation?). So if you see her recent "work" she is much thinner, and her ass is not so out of this world awesome. But she is totally buffed! Of course, some may find that she has crossed right into their "territory"...
