Masumi, a plump, busty mature woman in her fifties, married for 25 years, kills her husband Dango in a motel room. After the funeral, she and Dango's mother Junko are left behind to mourn her late husband. Then, men claiming to be solar panel contractors come to collect the accounts receivable for the large number of solar panels Dango ordered. Masumi, a widow, cannot pay such a large sum, so the two unscrupulous contractors attack her, raping her in front of her son and grandmother, and filming the live performance. They then threaten to sell the widow Masumi as a sex slave through the overseas mafia to a European bourgeois who loves Japanese mature women, and even get her son to rape his mother. This 230-minute work features 11 scenes of lustful widows in their sixties, fifties, forties, and thirties, whose lustful widows are hidden in black mourning clothes. This is a high-quality adult entertainment piece that will soothe men's bodies as the new school year begins.
