The Breastford Wives (2007)

Young married couple Rob and Laura move to the peaceful, friendly town of Breastford and right away are made to feel at home by the welcoming members of the Breastford Womens Association. They soon realize that something is amiss, and they discover the reason: Doc Brady, the town's mayor, has invented a device that, at the push of a button, turns women into insatiable, sex-crazed robots.
