There’s a sexy film series from Australia that if you don’t know about you should. It all began with Alvin Purple (1973), which features a slew of sexy nudists, none more desirable than Kris McQuade, a fiery redhead who has gone on to fame and fortune on the Down Under boob tube but first showed her boobs here. She even showed up (and just plain showed) for the sequel, Alvin Rides Again (1974), where Kris continued her full-frontal streak and sadly ended it. But since fifty is the new thirty, Mr. Skin would love to see her mature mams again.
