Kayoko has a plump, sexy body and is chronically sexually frustrated. She is not satisfied with sex with her husband, and even flirts with her father-in-law, who lives with her, and devours his dick. When a single man comes to say hello after moving, she seduces him even though they just met, and tries to make him ready to have sex anytime. She also secretly sucks the dick of her husband's colleague, a sexually-crazed housewife monster.
