Shock Treatment.

A warning from the producers: This film portrays realistic and authentic BDSM and fetish sex. These are not actors, but experienced BDSM players doing what they love to do. This is hardcore extreme sex at its most raw and most realistic, and should be viewed only by those that can handle it. In the DVD's bonus features co-star and co-director Tony Buff talks with Derek Da Silva, Element and Mitch Colby in three enlightening interviews that stress the importance of safe and consensual BDSM play.
