The Petting: Suttekamu.

The man, a self-proclaimed "detective", makes a living selling used school uniforms, which were popular at the time. A young girl named Lisa comes to sell her sailor uniforms, but the detective says he'll raise the price if she lets him film her petting and fellatio, and Lisa agrees. The detective also runs a "breakup agency." One day, an elegant young wife, Harue, comes to him to ask for an investigation into her husband, Masayuki's, infidelity. A world of infidelity and passion unfolds with the detective at its center. Directed by Hashiguchi Takuaki from a screenplay by Nazono Tou Hankojin, this must-see work delves into the sexual lives of men and women who are not satisfied with normality.
