Well there's Diddy (Diddilicous, Diddy Does it etc.) Kirsten (Kirsten's Room/Kirsten's Bedroom) Reanna May (I recon being fondled and fingered in your pussy by the camera man counts as HC )(various sites) and I guess Katie from Katiesworld. That's how far my memory stretches right now.
BTW if we're thinking of the same Karen, she did HC before she did her NN site go figure
2 of the girls who were on the old MXPhoto site with Reanna went on to do hardcore. Lonnie uses the name Lonnie Waters when she's doing porn. (Dunno if she is still making any new stuff, her website at lonniewaters.com is still up). Monica went by Boo D. Licious (who makes up that shit?) during her time as a porno actress, though I know she's retired.
I'd really love to see a MXPhoto reunion, with the porn girls bringing Reanna over to the darkside. I'd join that site pretty fast.
I think this thread is drifting. Personally I am really looking for girls that get a dick or at least a dildo inserted on film, not the topless stuff. Otherwise we can have over 50% of girls that were NN when they started.
Pornstar Charlie Laine was a teen tease NN model on the Photostudio 17 site way back in the day, before she hit legal and went on to hardcore. Her NN days were a while ago, but that's where she was first seen when she wasn't yet 18.
