If your wife and children don't play, leave it to dad

Do you know what makes family happiness easily lost? That is the issue of sex in marriage and Mari Takasugi in this movie married a husband who did not care about that at all, just forever going to work and then coming back to sleep.
Her father-in-law knew about this so he was determined to help her. They both took advantage of the time when her husband often went out to smoke (he was very addicted to smoking), in just 5 minutes they did it. Their love for each other was extremely intense until her father-in-law shot semen, and every day, the affair continued.
