Forbidden Love Game

Quite the kinky little ride. To expand on the synopsis, the couple are brother and sister and are running away to consummate their love, and the teacher picks them up and keeps them prisoner in his isolated mansion. Sub/dom, sexually-tinged games ensue. How did Moulder-Browh end up in this? He clearly isn't speaking his own Spanish, and he's a lousy actor (the rest are just fine). It's hard to tell if this is meant as commentary on dictatorship. I suspect/hope not--it's too silly to manage it .
