The days of sleeping with my best friend

His wife was suddenly busy with work and had to return home quickly, so the guy in this movie told his wife to stay at his best friend Yuna Ogura's house so that someone could take care of the food and not have to feel sad about living alone. Because she trusted her husband and knew that they had known each other since childhood and had been close friends for a long time, she felt secure in going. But unexpectedly, for her husband who still has no thoughts about cuckolding her, despite being faithful, his best friend is extremely lewd… In the end, after 10 days of sleeping together, her best friend was pregnant.
