I witness a beautiful wife, Nao, who is suffering from a nightless life, and her husband is sensual. Knowing that her husband, who does not hold herself for half a year, is not impossible, she lost her sexual desire as well as her self-confidence. One afternoon, when she raised her face while rubbing her crotch alone, her eyes met through the window with her middle-aged neighbor, Shirai, who appeared in the moving greeting. The two who should never have met will have a relationship that makes them sweaty after witnessing this masturbation.
