Recently, Makoto has been sexually frustrated due to the lack of nighttime activities with her husband. Her body, filled with pent-up desire, begins to crave her cohabiting father-in-law, and she starts to provoke him in daily life. When helping him change clothes, she deliberately shows her cleavage or sticks out her butt to show her underwear. The father-in-law also gradually becomes aroused, and the two begin to desire each other.
