"If I had to choose between kissing without sex and sex without kissing, I might choose kissing without sex..." says Ryoko Izumi, 56, a full-time housewife who loves kissing so much. She is a mature wife who is now in her 30th year of marriage and living a carefree life. "Even if I get older and can no longer have sex, I want to continue kissing... That's how much I love kissing (laughs)." Ryoko still makes love to her husband once a week, but she is getting tired of the sex with him, which has become less intense compared to before. She wants to experience a more sticky, intense, melting erotic relationship between a man and a woman, so today we will be following our instincts to the fullest.
