Brother returns home after deciding on his solo assignment at work. His wife, Hibari-san, remains alone. One day, she visits my room. It turns out that brother and I share the same perverted interests; we had somehow known about the explicit contents of the videos we watched together.

Their sexual encounters began as a means to alleviate their loneliness, with Hibari-san taking full advantage of me.
