OFSD-034 I'll take the whole parasitic lowlife family, wife and daughter included.

A low-class family parasitizing on a rich family! This low-class family fabricates a traffic accident, exploits the weakness, and invades the rich family's home. They enjoy comfortable housing and meals... eventually even seducing the beautiful wife and sisters!! The wealthy Matsumura family consists of a father, mother, two daughters, and a son, totaling five members… The free and affluent life suddenly changed because the father caused a traffic accident! From there, everything changed drastically like rolling downhill! The poor and vulgar Narijima family, who we took in after the accident, started to impose themselves on us. Although our physical relationship was fading, my beloved wife was taken by the other man right before my eyes. My eldest daughter Misuzu and second daughter Ai were treated like sex toys, and even my son Shinji was devoured by the Narijima family's slutty eldest daughter. And even such an abnormal situation gradually became the usual, unremarkable daily life. My wife and daughter were dominated by lust, transforming into wanton women of their own accord! Our Matsumura family was completely falling apart...
