How Did a Nice Girl Like You Get Into This Business?(1970)

Original title: Mir hat es immer Spaß gemacht

Playboy magazine darling (and one-time playmate of Hugh Hefner) Barbi Benton is Naughty Cheerleader Lynne Keefe, a small-town, small-brained babe who gets caught up big-time in the sex business. As a high school cheerleader who can really twirl a baton back in hometown Scranton, Lynne gets knocked up by a horny hunk on a motorcycle who then dumps her, sending her into a sexual spiral that takes her to The Catskills, Boston, New York, Miami and Rome.
