It’s easy if you include out-and-out porn films like Debbie does Dallas etc., but from mainstream films, yes, Jane Fonda was always fuckably erotic, and in particular as the prostitute in Klute as mentioned. My other favourite lady of that era was Catherine Deneuve (who still looks great today in her late ‘70s, if a little fuller in the face), and especially as the part-time prostitute in Belle de Jour. Mainstream soft porn films like The Story of O back in 1975 were also good. I’d have fucked the delectably submissive Corinne Cléry any time.
But coming back to porn films, Terri Hall in The Story of Joanna, also from 1975, has some great S&M scenes. Not too graphic by today’s standards, maybe, but her being triple-penetrated!.........
