Akari lives a comfortable and unrestricted married life with her kind husband. However, she has one complaint: living with her lewd father-in-law. When Akari falls asleep from exhaustion during the times when her husband is not home, her father-in-law finds her and gazes at her firm breasts and glossy black thicket. The father-in-law, having seen his daughter-in-law's private parts, turns into a beast in heat and sets his sights on the young female living under the same roof.
