"The first time I masturbated was when I was a student, so it's been 30 years (laughs)" Shiori Maezono, 40 years old.When she was itchy and fiddling with her, she felt better and it seemed that it had become a daily routine.She didn't know it was called masturbation until she was in middle school.Even after she got married, she kept secretly hiding from her husband.She originally had a strong libido, but it increased even more after she gave birth.Because of her strangely serious personality, she had been unable to cheat on her until now, but at the age of 40, she took the plunge and decided to appear.A full-time housewife who has been married for 12 years and a mother of two boys, continues to knead her clitoris in her first unfaithfulness and exposes her dementia.
