Cindy and Donna (1970)

Seventeen-year old Cindy is in awe of big sister, Donna’s sexual exploits, but she just doesn’t get it. Whether she’s spying on Donna, parked and “makin’ it” in the driveway with her boyfriend, or watching her bang dear ol’ stepdad, Cindy is curious but timid. But “don’t be afraid, Cindy” instructs the dreamy, ballady, canned-cheese 70s soundtrack, as Cindy inches her way toward womanhood.
