Underground Married Woman Torture and Rape Butt Club ~ A dangerous bet fought over plump bodies ~

One day, Yukari goes to the beach with her husband and drinks alcohol at a bar and loses consciousness. When Yukari wakes up, an unknown man in black is standing there. That's right, her husband, who owed a large amount of money, offered Yukari to a dark organization in exchange. And where Yukari is taken, there are Naho and Mari, who live as gambling pawns in the underground gambling "Tojiri-kai" held in the basement of a warehouse at the port, and they say, ``Hell begins tomorrow.''
