A married woman who has been married for two years, Ichika. At first, she was good with her husband, Mitsuru, but recently, due to the stress of her work, there was no night activity, and Ichika’s body was terribly aching. Her father-in-law sees through her loneliness and asks her for advice… Despite her singleness, her father-in-law, who had a secret admiration for her Ichika, took advantage of her weakness and pushed her down at once. Her Ichika’s body, which was groped for the first time in a long time, can not resist her pleasure, and she accepts it as it is. Of course, her father-in-law’s desire, which occupied her taste, could not be satisfied at once.
