Ricordi di notte
This is one of Karin Schubert's first 'proper' hardcore pornographic films, if not the first (I am not counting her non-simulated sex scene in Black Emanuelle). We are constantly reminded of this, because many of the sex scenes that don't involve Karin in persona are inter-cut with shots of her watching from the side. This does not serve any real plot purposes, it's just the director shouting at his audience 'Hey, it's Karin! In a porn flick!'.
