What I can remember about it is that they were teacher and student?Or at least younger-older relationship. At the start, the young one is the sadist one and kepts the old one in a big cage, the masochist was looking for someone that would never leave him ,not break and 'submit' no matter what, cause his other partners always ended up submitting their masochistic side, then shows his true colors and kidnaps the young one and they switch roles and something like that the young one ends up being "the one" that would never surrender
