Nagisa Shinohara loses her husband, but not her sex drive, and spends her days masturbating while thinking of him. When her brother-in-law approaches her, she initially refuses to betray the memory of her marriage, yet her body responds honestly to his lingering caresses. Aroused beyond restraint, she is pounded throughout the home filled with memories of her husband and ultimately allows her brother-in-law to creampie her, climaxing even harder because she knows the affair is forbidden.
