Vivianne and Ashlyn, curvaceous teens, find themselves at the mercy of their stepdad, Peter. Ignoring their disinterest, he indulges in his twisted free-use tactics. Vivianne, thick and luscious, is first to feel his unwanted attention, her protests unheeded as he uses her whenever he pleases. Ashlyn, equally enticing, is next, her attempts to avoid him futile. Together, they fantasize about a normal family life, but their reality is a taboo, fucked-up dynamic where they're always available for Peter's gratification.
