Seiko is a 38-year-old housewife. In fact, until she met her husband, she was only interested in 2D characters and was an otaku. As fellow otaku, they hit it off, and she devoted her mistress, which had been complicated until she was 35, to her husband, but perhaps because they both had no experience, they were unable to exceed his expectations. This complicated wife, who wants to know the true pleasure of sex, once again has her true first experience!!
