Sayuri comes to Tokyo to support her pregnant adult daughter. The husband is trapped in a cold war with his wife and forbidden from drinking or even masturbating, yet he resists his mother-in-law's mature allure. One night he confides his work and marital troubles. Sayuri strokes his head, lets him lean on her, then apologizes for the hardship her daughter has caused while reaching toward his painfully swollen crotch—leading to repeated breeding sex.
