Ayako was hired as a housekeeper to take care of her son Atsushi while her father was posted overseas. A few months after she started working... Atsushi, who brought her lover home, was planning to have sex with him for the first time, but he was worried because he couldn't get excited when he saw her lover's pants. One day, when Ayako was sweeping her garden, her skirt was blown up by a strong wind. Since then, Ayako thought that she could solve Atsushi's "sexual worries" by showing her panties.
