I'm more of a mouth/teeth fetish guy, but like a good biting video.
Eliza Divine, some of the sexiest teeth around. This is a sample of her biting a guys fingers. One of my favorites because you can really see her teeth in this vid. Her C4S store is All things Fetish. BTW, my VLC doesn't like this clip but all others play it fine. And clip is called Tooth and Nail, I think.
