Gotta love those dark assholes (just wish that this chick had shaved her snatch -- I don't like the pubic hair).

The asshole on this red-headed wench isn't quite as pigmented as one might hope, but still...

I wish the pigmented area were a bit bigger on this chick (and I wish there were some close-up shots of her anus), but the girl is good-looking, and the photographs have some artistic value.

 Does anyone know her name and where else we could find her?
