Buster and Billie (1974)

Synopsis
In this coming-of-age movie from 1974 that mines the same territory as Summer of '42 and Class of '44, Joan Goodfellow plays Billie, an obliging blonde more than willing to dispense sexual favors for a group of horny high schoolers in rural Georgia of 1948. The only member of the high school group that doesn't seek out Billie is Buster (Jan-Michael Vincent), who is faithful to his fiancee, Margie (Pamela Sue Martin). But when Margie insists on preserving her virginity until their wedding day, Buster joins the crowd and seeks out Billie himself. Buster is so taken with her that he begins to openly date her. Because of their relationship, Billie has changed but the townspeople and the high school students react with disdain when they see Buster and Billie holding hands. The disdain turns to hate, then to violence. ~ Paul Brenner, All Movie Guide
