Chloe is my number one, hands down. She's gorgeous and has some of the biggest and most beautiful breasts I've ever seen. Also, she has an incredible body otherwise. Great ass and legs. Not everyone likes muscular, defined "soccer girl" legs, but I love them. Here's a great example of what I'm talking about.
EDIT: Oh yeah, and I also love the fact that she actually has pubic hair. When I say I like natural, I mean it.
