Since bringing his wife home, the husband has had a bad feeling about some things in the family. Unfortunately, his intuition was completely correct when the despicable father-in-law always kept an eye on his beautiful daughter-in-law, Hoshi - his wife. The old man always secretly peeked at her moments of vulnerability to reveal his enticing large buttocks, and it was precisely this oversight that led to many unforeseen events. One day, when the husband left for work early, leaving only the two fathers and daughters at home, thinking the opportunity was too good to miss, the old man entered the room, dragged his daughter-in-law out, and raped her. Due to her timid personality and petite figure, she could do nothing but endure this despicable act by the old man. Yet, even so, unable to satisfy the lust within him, the unfortunate fate of the daughter-in-law still lies ahead before having to live with the perverted father-in-law.
