Akemi, Minako's only daughter, is pregnant. After the baby is born, it will be difficult for the family to go out together, so her daughter and son-in-law invite her to take a "family trip" before the baby is born. Minako is grateful to Akemi's husband, Shinji, for his consideration, and soothes her fatigue by soaking in the hot springs. That night, after Shinji puts the pregnant Akemi to bed first, Minako and Shinji drink together. How much time has passed? Shinji is seen looking at the completely drunk Minako as if licking her all over.
