Found this available in DVD. I had no idea what to expect. The blackmail plot was pretty implausible. Whether by original casting or the passage of time, the "girls" looked far more like college age, than high school. So no real exploitation in that aspect. This had good, crisp, black and white photography and struck me as a missing link, somewhere between THE KNACK (And How To Get It) (1965-UK) and FASTER PUSSYCAT KILL KILL (1965). One woman's outfit reminded me of Tura Satana from PUSSYCAT. I wonder in which order they all were made? There's some pretty brisk nudity and sex, but all soft core. That said, it's a great timepiece, I'm glad I saw it and would give it three stars.
