Kinkorama (1976)

The plotline finds Cindy "frigid," so Dr. Gloria Leonard puts in a tape to thaw her out. The tape consists of Euro loops with a voice-over by a doctor with the worst German accent since Hogan's Heroes. These loops are the most depraved, kinky, slimy kind of Euro-trash sleaze that appealed to the Times Square crowd, which reveled in this type of stuff. The loops showcase sex acts so dirty and disgusting that you can almost catch the scent of unwashed pussy and manly body odor wafting off the screen. Of course, the frigid Cindy thaws out a little more with each act of perversion she watches.
