Kanzen naru shiiku: akai satsui AKA Perfect Education6 (2004) - Koji Wakamatsu

Cult director Koji Wakamatsu (famous abroad for titles such as "Go, Go Second Time Virgin") returns to helm the sixth in this perversely entertaining series. A Kabukicho gigolo with a gambling debt Mikio Osawa agrees to bump off a rich wife's husband for a bundle of cash, but botches the hit. On the run in the snow-covered hills of northern Japan, he holes up in a shuttered, deserted house. But the house is not empty: a timid, traumatized girl Mika Ito lives there, in the thrall of a sick, hot-tempered trucker Shiro Sano who has kept her there since she was a tiny girl. Osawa tries hard but looks out of his depth here, as veteran Sano and 23-year-old ingenue Ito build an all-too-believable, monstrous relationship as sadistic paternal pervert and terrified tremulous child. File under guilty pleasure.

Szamanka (1996) - Andrzej Zulawski

From IMDB:
Director Andrzej Zulawski's adaptation of Manuela Gretkowska's controversial screenplay tells the story of an anthropology professor Michal's (Boguslaw Linda) who as the movie progresses develops two overwhelming obsessions. The first one is a mummified, 3,000 year-old, perfectly preserved body of a Shaman he and his colleagues have recently dragged out of a swamp, and the second – an enigmatic student (Iwona Petry) he meets by chance at Krakow Railway Station. In exactly a minute after they meet, they have passionate but joyless sex "The Last Tango in Paris" style. The girl whose name we'll never learn has been known as "The Italian" – she is not an Italian, she just used to work at the Italian Restaurant and make the best Pizza in town (or so she says). She emits some primitive, dangerous sexuality - she is unpredictable, swift and reckless. Very soon she and the professor are engaged in the affair that grows dark and explicit...
