Nikki Fritz is indeed the best soft-core actress (Or Erotic Thriller to be technical). She is absolutely fabulous. The lesbian scene with LeAnna Scott on NightCap is a favorite. It's funny because if you watch a lot of the soft core flicks from the mid 90's Nikki is in a bunch of them in small roles and you can't really even tell it's her.
I always liked Shauna O'Brien until she got the enormous implants. They were great initially but the luster wore off quickly.
I miss Athena Massey who definitely should have done a lot more in the mid/late 90s. I have no idea what happened to her. I think she got married and had kids but I'm not sure.
I'm probably dating myself with these names but Julie Strain, Rochelle Swanson,Shannon Whirry, Julie K. Smith were all favorites.
