Just to name a few pornstars I'd like to come back:
Farrah - One of my very first favorites, and unfortunately probably also the one I've seen the least of.
Dasha - another big favorite with me, and for nearly as long as Farrah. Simply amazing to watch in both pictures and movies.
Sydnee Steele - I've known her for as long as I've been watching porn/adult films. She wasn't a favorite when I first discovered her, but lately I've begun to really like her work.
J.R. Carrington - I haven't actually known her for many years, but I've loved to watch her in action ever since I first saw her. I'm still amazed at how much she seems to enjoy it in the movies I've seen. Stunning blonde, and one of the greatest performers IMHO.
