A younger brother living with his older brother and his wife. Recently, he is told by his brother's wife, who is worried about his brother's late work hours, that she has something to consult with him. The younger brother, who has feelings for his brother's wife, sets up a camera and waits in the room. It seems his brother is going on a business trip from today. While drinking and talking, his brother's wife gets drunk and clings to her younger brother, who is kindly listening to her consultation. When the younger brother rubs his brother's wife's voluptuous breasts, she feels something and has sex with him in a drunken haze. In the bathroom, they engage in a husband-and-wife-like playful play. The next morning is a self-shot creampie sex. This is a secretly filmed & self-shot post.
