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

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 in 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, to Boston, New York, Miami, and Rome.
