Gianna, but they are all curvy Goddesses ...
First off, you've picked an excellent set of very curvy women -- especially Gianna and Sarah Jay.
I have to pick Gianna Michaels, not merely because she has the most natural set of curves all-around, but because she reminds me of actress Nikki Cox from the neck up, only she is even more beautiful (and a hotter, darker brunette). I could melt in those eyes all day, and that's before I get to experience her body!
Now Sarah Jay is also very curvy, and I'm more than willing to look past her enhanced breasts to see her overly-curved form -- front and side. I almost totally lost it to her "no hands tit-fuck" video, where the guy just starts unloading as she's hanging those puppies all over his manhood. But she's even better when mounted on a rod or just showing off that body.
I'm not trying to take away from Ava Devine, especially since she has a mouth that just makes a man cry and act like a child. She is one sweet looking brunette, but I don't find her curves quite as extreme all-around as Gianna or Sarah. But she is still beautiful nonetheless, and I'd be lucky to have such a beauty on my arm (let alone atop of my rod).
(and yes, that's a "Big G" because only women who are made in the image of God Herself's own image can have such fine curves!)
