'Schoolgirl Hitchhikers' (1973) – Jean Rollin.

Uncommonly handsome couple Monica (Joëlle Coeur) and Jackie (Gilda Arancio) make for two expressly delectable nubiles who are currently trekking across the no less breathtaking French countryside, exhausted after their long walk, they happily discover a rather grand-looking, somewhat isolated country house, seemingly empty, Monika and Jackie gleefully Goldilocks their way inside soon finding a bed to begin their fulsome frolics! Colourfully, and with pleasing alacrity, director Jean Rollin dispenses with the tawdry business of exposition, zestfully replacing filigree plot with a sublimely sensuous sequence of sinfully supple sapphic congress, wherein our two picture perky, perfectly pale-skinned, long wondering waifs slink sensually into one another's slender arms. A little time after their unhurried, amorously explicit interlude has concluded, the still needful Monica restlessly goes to the porch for a soothing smoke, only to somewhat less than anxiously discover that they are no longer quite alone, since they have inadvertently sheltered in small-time hood Fred's (Willy Braque) secluded hideaway, and after the majestically moustachioed Fred, Monika and Jackie proceed to ménage a trois with laudable energy, Jean Rollin turns up the grindhouse heat with additional lashings of gratuitous gun-play, titillating bouts of torture, exceedingly phat-sounding drum breaks, and the forceful introduction of a tooled-up private dick, 'Schoolgirl Hitchhikers' is a luridly episodic delight, while, perhaps, one of the more, shall we say, roughly hewn gems in maestro Jean Rollin's mercurial, multi-faced genre oeuvre, but enjoyed as a B-Movie bite of vintage saucy smut, it's pretty flawless! And rabid Rollin fans will most certainly enjoy the great man's audaciously Red-turtle-necked cameo at the very end!
