"My boyfriends have often told me that my nipples are erotic," said Akina Kataoka, a 36-year-old full-time housewife who spends her days comfortably surrounded by her husband who has been married for 10 years and an 8-year-old boy. Akina says that she enjoys masturbating 15 times a week, but she says that she is not satisfied with sex with her husband once or twice a month. "Masturbation while watching an AV where a married woman is being nipple tormented is exceptional (laughs)."
