20 BDSM Movies More Provocative Than Fifty Shades Of Grey

8. Story Of O

Released the same year as Maîtresse, the 1975 French-German co-production The Story Of O was similarly refused a release from the BBFC, although it was eventually passed in 2000. An extract from the synopsis of the plot from Wikipedia tells you all you need to know about why the film caused such controversy: "O is taught to be constantly available for oral, vaginal, and anal intercourse. She is regularly stripped, blindfolded, chained and whipped; her anus is widened by increasingly large plugs; her labium is pierced and her buttocks are branded." Understandably, The Story Of O has become something of a classic for fans of BDSM.
