A younger brother living with his older brother and sister-in-law. Recently, the sister-in-law has been worried because her husband comes home late from work. The younger brother has feelings for his sister-in-law, who says to him, 'Can I come into your room? I want to talk about something.' The younger brother sets up a camera in the room and waits. Starting today, the older brother is on a business trip. They drink alcohol while having an honest talk. The sister-in-law also suspects this business trip. The younger brother kindly listens to her. Both of them get drunk and end up having sex. The younger brother also secretly films them in the bathroom and kitchen. The next morning, the younger brother says, 'For memories...' and, excited by her mature and voluptuous body, he records their sex and ejaculates inside her extensively.
