Renee Fern followed the traditional progression of models expanding their heat levels and boundaries. She started with nudity, then did girl-girls (with Russian Kathy and Annette Christianson) and played with cock-shaped vibrators. In other words, toys but no boys. In the girl-girls, there was mutual spreading of pussies and licking of nipples but no lip-to-lip, old-fashioned kissing. This is one of the odd things about porn which has been discussed many times on porn forums and in adult magazines. After her adult modeling, Renee became a fashion and clothing model.
