The History of BDSM

IMDB

My Mistress is a 2014 Australian drama film. A teenage boy, struggling after the death of his father, forms a relationship with a lonely older woman who turns out to be a pro-dominatrix. 

Despite the title and the promotional images, My Mistress is not primarily about a BDSM relationship. It belongs in the category of films about the male fantasy of being initiated in sex by an older attractive woman. E.g. Private Lessons (1981), Class (1983), My Tutor (1983), They’re Playing with Fire (1984), and even Weird Science (1985). Right away, we’re getting into some difficult areas about consent and double-standards about sex between younger men and older women. (For the record, the age of consent in most of Australia is 16.)

Charlie, a teenage boy, aimlessly bikes around his neighborhood. He sees an older woman with a French accent, Maggie, move into a house nearby. He returns home, only to find his father has committed suicide. Soon after that, he learns his mother has been having an affair. 

Distraught, Charlie forms a casual relationship with Maggie. He bikes to her house and goes inside. He goes upstairs to find her playroom where she is in full dominatrix dress and in mid-session with a man. He runs off.
