Mio Kimijima, a beautiful wife, started thinking about having children calmly in her marriage in the housing complex. However, instead of making a child, she was hesitant to work at night, and her husband’s attitude led her to have daily sexual desires, and she occasionally comforted herself. One afternoon, while lifting her face while caressing her sensitive areas, she saw her middle-aged neighbor Takeshita, who appeared in an emotional greeting, through the window. The two, who should never have met, would develop a relationship that made them sweat buckets after witnessing this act of masturbation.
