Kataoka Mayu (28 years old, housewife), whose natural H-cup breasts are clearly visible through her white sweater, patiently waits at home every day for her husband to come home. Meanwhile, Yoshida Erika (32 years old, housewife), with her natural personality and slightly saggy F-cup breasts and her tendency to "take whoever comes," lives a loose life, grabbing the dick of her next-door neighbor, Kataoka's husband, without a shred of guilt. So begins a sloppy love-hate drama as the two neighbors compete for each other's husbands!
