I went through a gallery or two of BP's. Well, I only have an educated guess, but Mediterranean sounds very possible. I'd say that in a photo like this one, she looks more Greek than black. Not a "classic" Greek look though. For me, classic Greek is Tori Welles. I don't know that Tori is Greek, but I'd truly be shocked if she isn't.
Of course, BP could be a mix... which makes things a lot tougher.
Damn, I can't believe I forgot Anna Amore, Dominique Simone, Persia and Heather Hunter since growing up they were mostly the ones I watched, along with Ebony Ayes. There was another one who was another favorite of mine, but I totatly forgot her. Looks like I'll have to go through all the porn sites to find her.
