Subdola ossessione

A middle aged lesbian pedophile teacher at a boarding school grooms a straight underage female pupil.

She showers her with gifts to gain her trust her, and graduarly starts behaving more and more inappropriately, giving her birth control pills, phone, a key to her apartment, Pretending to be her friend, when all she's really doing is thinking of raping her.

All through the film teacher has a creepy look on her face, watching the student in a gross way. I guess the moral of the story is that sexual predators come in all forms. Not worth watching if that sort of thing grosses you out.
