Rio Ishihara, 27, is a perpetually cheerful wife whose innocent smile hides an unexpected fantasy: she enjoys searching for rape-themed porn and wants to act out consensual forced-sex role-play, though she firmly rejects the real thing. Married for four years, she raises a child while working in the office of a massive distribution center. Frustrated by how rarely she and her husband have sex since childbirth, she finally enters the porn world she has long watched from afar. Her sweet smile and dirty fantasies make an irresistible contrast.
