My husband went on a business trip for a month. Ayumu, the daughter-in-law who was supposed to take care of her father-in-law. Sex of a brutal father-in-law who gradually wakes up in a joint life with a young woman. A forbidden carnal life beyond age begins. They let me eat rice mouth-to-mouth, urinate on me, and even in the shower... if I show my love, I'll be inserted!
