Waka has been married and living with her husband with her father-in-law for three years. She is always happy except... Her husband doesn't like having children and doesn't like sex. Since knowing this, Waka has always felt depressed, she wants to have children as well as her sexual desire is very high. Now neither of her husbands wanted to satisfy her. Seeing his daughter-in-law's appearance, his father-in-law kindly asked him and shared his feelings with her. Accidentally dropping her underwear, she discovered that her father-in-law had picked it up and used it to masturbate. From that moment on, she came up with a bold and extremely wrong thought... Seducing father-in-law! Although he was extremely confused at first when his daughter-in-law approached, his beautiful face and charming body in see-through pajamas made him quickly forget everything and rushed to enjoy sexual pleasure with his daughter-in-law. They made love to each other almost every day until Waka got pregnant...
