After a fairly uninspired three-year period, Nikkatsu studio director Shogoro Nishimura returned to form with this entertaining softcore melodrama about a college student named Kiyoshi (Tsuyoshi Naito) who lusts after the daughters of the bookstore where he works. He rapes the older one, Mioko (Yuki Kazamatsuri), but she doesn't really mind because she thinks he's cute. He helps her younger sister, Masako (Chie Yamaguchi), get an abortion, a favor which is rewarded with sex. Eventually, Kiyoshi really gets his fantasies fulfilled when he sleeps with both sisters at once. Nishimura's skill with actors and the story's strong wish-fulfillment elements resulted in two sequels, both directed by Yasuaki Uegaki.
