After suspecting his wife's strange behavior, the husband discovers the truth through a hidden recorder.




















Kiriko has a past where she was violated by her stepbrother eight years ago and experienced an orgasm. A chance reunion changed her fate. Her stepbrother's words, 'I can't forget that time,' reminded her of the fact that even though she was pinned down and taken roughly, she had cried out, 'Ah, it feels so good!' That illicit pleasure came rushing back vividly. Kiriko opens herself up to him. The fleeting sex that follows—a mature woman indulging in momentary pleasure without a thought for her husband's suffering—is maximum excitement. I give high marks to Kiriko Nio's seductive performance.
*This is a work in which a wife is cuckolded by her younger brother without her husband's knowledge. The story of the wife gradually becoming attracted to her younger brother is a familiar development, but I think it's well-written. However, I felt that the scene in which the husband set up a voice recorder because his wife's behavior was suspicious was not used effectively. Furthermore, I didn't even feel it was necessary for my husband to appear.
