My husband's single assignment is unbearably painful for my wife, Yumi, who is in the prime of her life, and I have a relationship with another man before the year is over. However, his neighbor, Koichi, who enjoys watching it secretly, comes up with a plan with his bad friends... One day, Koichi, who visited her Yumi, entwined Yumi with a special restraint without telling her or not, and trampled her plump body. Yumi is deprived of her freedom and continues to be a toy for bad boys, and her body and mind are eroded by her humiliation and pleasure every day.
