Yuka Yoshizaki, 38 years old. A part-time bookstore clerk and a mother of one child who has been married for 8 years. During her school days, Yoshizaki devoted herself to naginata from junior high to high school. 'I had a tough and old-fashioned way of thinking, so I never thought about having an affair... When I was first betrayed by my husband, I got so angry that I ended up playing around with a matchmaking site. Then I got hooked more than I imagined (laughs).' Having tasted the pleasure of infidelity, she decided to apply for more stimulation. 'I want to feel even better!' A refreshing smile of a martial arts-loving, naughty wife with a core of a single blade, please take a look!!
