My favorites are Suzie Q, Marie, Aria Giovonni and Axelle Parker. I can't pick just one overall because these five are tops for different reasons.
Suzie Q: Great face, great body, amazing movies.
Marie: Very hot overall and a very dirty girl.
Aria Giovonni: Seriously, do I need to explain? Wow!
Axelle Parker: Very hot overall, very dirty, very seductive
Lucianna: She's just so damn beautiful and natural looking
I have one least-favorite and that's Felina. She is the only model I disable and the only 0-star rating I've given. She is just so fake in every way I can't even look at her. That boob job is just *****. No offense to any of her fans, I'm not criticizing your tastes.
