A younger brother living with his older brother's couple. Recently, the sister-in-law, who has been worried about her husband coming home late, asks him for advice. The younger brother, who has feelings for his sister-in-law, sets up a camera and waits in the room. Starting today, his older brother seems to be on a business trip. The sister-in-law, who loves drinking, spews insults about her husband after getting drunk and leans on the kind younger brother who listens to her problems. He gropes her ample breasts and steals a kiss, and they end up having sex in their drunken state. That night they share a bed, and the next morning they have sex while being recorded. This video captures his sister-in-law's lewd behavior and has been posted online.
