12. LIES (1999)

OK, so we have a 38-year-old sculptor and an 18-year-old student meeting in a motel to engage in hardcore sexual intercourse. We’ve all seen that, and there’s nothing too crazy about it, right? But wait, it’s not just fellatio and anal; it’s a sadomasochistic relationship, which involves brutal beatings and spankings.

Over the course of two hours, we’re shown more sex than you'd see in most porn flicks; interestingly enough, Lies was made in Korea only a few years after its censorship liberalization. Don't watch this with your significant other, unless she's into that sort of thing.
