In a small family in the suburbs of the city, there is a young couple living with their extended family. To outsiders, they may seem like a happy and cheerful family, but little do they know that there are many other mysteries hidden deep inside. The husband is unfortunately impotent, while the young wife is in her prime and always craving sexual intimacy. Sometimes, when the husband "finishes early," she has to watch adult movies online and masturbate to satisfy her desires. Of course, the older brother knows that his sister-in-law is lacking something, and he is just waiting for the right opportunity to make his move.
