Yukie, who had caused a traffic accident, was demanded an outrageous settlement by Taketo, the son of Nogawa Industries' president. Unable to pay, Yukie reluctantly offered her body as compensation, but it was all part of Taketo's sinister plot. Nogawa, Taketo's father, used Yukie's affair as leverage to coerce Rumi, and even targeted Tomoko... What fate awaits the mother and daughters who have fallen into their trap?

Taketo's father, President Nogawa, invades Yukie's home, still craving the flesh of Yukie and Rumi. Despite the dire situation, Yukie is tormented by her youthful desires, while Rumi trembles with pleasure at the cunning techniques used on her. As they watch their mother and sister being defiled with a mixture of shame and ecstasy, Tomoko also begins to stir with lust. Is this the fate of those who are bound by lascivious blood?

The humiliation inflicted upon Yukie and Rumi knows no bounds, and eventually, even Tomoko loses her virginity to President Nogawa's schemes. The sisters, now completely enthralled by sex, indulge in each other's bodies, seeking even greater pleasure. Amidst this debauched feast, Yumi, President Nogawa's secretary, plots her revenge against him...

Taketo's still living with the Nogawa family, and things have gotten pretty twisted. He's been having sex with Yukie and Rumi, and they're all just trying to navigate this messed-up situation. Then Kunihiko, the father, comes back from his business trip overseas, and it's clear he's got some desires of his own - especially when it comes to his daughters... Tomoko's trying to hold on to some sense of normalcy, but her body's craving something more. Meanwhile, Yukie's still devoted to her husband, even though he's not exactly capable of satisfying her anymore... As the family tries to figure out what's going on, things start to fall apart...

Kunihiko's furious when he finds out about Taketo's relationships with his daughters, but it turns out he's got some secrets of his own - like how he's been lusting after Tomoko for years. When she finally makes a move on him, he can't resist, and they end up having sex... Kunihiko's wracked with guilt afterwards, but then Yukie and the others propose that they all just start sleeping together to make things easier...
