Crissy Moran used to be my favorite. Granted, she may have fake boobies, but she's got great skin, a GORGEOUS face, and one of the NICEST asses I've ever seen. Also, she's one of the few who actually seemed to be enjoying the sex she's having on screen.
Unfortunately, like a lot of porn stars, she "found god" and doesn't do the nasty for my pleasure anymore :-(
