I think the first one I went totally nuts for was Taylor Hayes. Her insane enthusiasm for sucking cock and fucking just blew me away - and she was a doe-eyed babe, to boot!!
I think just a bit later it was Chasey Lain, but now I'm not so sure why. Her face is pretty nice, but her bod seems way too fake and bland to me.
Also, then Anita Blond and Dahlia Gray(Grey?), even though I don't think Dahlia ever did any boy-girl stuff - sadly.
