Pony Girl: At the Ranch 1986 on netflix

Young women are being kidnapped by a rich sleazebag and his goons and are taken to a farm. At night they are forced to sleep on a barn floor. During the day, they are at the mercy of a sadistic dominatrix who dresses in leather outfits and forces them to behave like horses. This video uses footage from Pony Girl (1985) and Pony Girl Number Two (1985), with Traci Lords edited out of the proceedings despite the fact there’s no X-rated material in the original tapes.
