Harley Davis is my favorite, by far.
Close second is Presley Maddox...guess you could say I have a thing for white girls with short black/dark hair.
I also love Gina Ryder, Rachel Starr, Lela Star.
Can't forget the straight up blondes that seem to aim for the Milf set....Jill Kelly, Nina Hartley, some Kat Kleevage, and a few others.
The Asian set, like Ava Devine, Lily Thai, Veronica Lynn.
Black chicks like Candace Von and Jada Fire (some of her stuff).
The mulatto bunch, Havana Ginger, Alexis Silver.
And honorable mention: Carmella Bing, Shyla Stylez, Gauge, Daisy Marie, Phoenix Marie, many of the girls from the "Exploited College Girls" series including Tiffany, Lisa Ann, and well....I think I gotta check out some of those sites now....
