Seiko Shirakawa Seiko, 38, is a full-time housewife. In fact, Seiko, an otaku who only loved two-dimensional characters until she met her current husband, hit it off as a fellow otaku and thought, "This is the one!" She devoted her precious chastity, which she had been complicated with until she was 35, to her husband, but perhaps because they were virgin couples with no experience, they were unable to exceed the anticipation of 35 years... "I couldn't get past the pleasure of masturbation at all, and I was like, 'Huh, is this what sex is like?!'" It was also a tragedy brought about by her insatiable pursuit and obsession with the pleasure of masturbation, which is rare for women. "I know that it's knowledge I've acquired from AV and erotic manga, but I know that it should definitely feel even better. But I don't think I can expect anything from my indifferent husband..." This complicated wife, who wants to know the true pleasure of sex, once again has her true first experience!
