A husband who recently began living with his wife's mother, Reo, accidentally catches her changing. He'd always found Reo's voluptuous figure attractive. Despite feeling guilty, his curiosity gets the better of him. Reo's corrective underwear, worn to address middle-aged weight gain, is stretched tight, accentuating her heavy breasts and shapely buttocks, making them appear as if they might burst out. Overwhelmed by her unexpected sensuality, the husband becomes aroused and spends the night looking for an opportunity to act on his desires.
