Sexless and desperate for excitement, married Kana and her friend Rena fall into shoplifting on a reckless impulse. One day a convenience-store employee catches them and takes them into the back room, threatening, “If you don’t want your families to know, take off your clothes.” They reluctantly undress, revealing breasts even larger than he imagined. The manager swallows hard and begins roughly kneading both women’s massive tits, using blackmail to force the two wives into obedience and turn them into his personal double-breast sex toys.
