At first, Hinata treats him lightly, but over the course of a month, he is conveyed with an aura of likes and dislikes, and their hearts grow closer. While his father is away on a business trip, he sleeps in the sun at night, and his son gets scolded by his mother, but he gets a breastfeeding handjob saying, "I can't help it." The next day, what did the mother do when her son asked her to let her have sex with the momentum of kneeling down on the ground?
