Shizuka Miwa, 33 years old, married for seven years. Working as a freelance web designer and mother to one child, she has a charming personality with a radiant smile and incredible charisma. Standing at 158 cm with voluptuous I-cup breasts, her stunning figure makes her highly desirable, yet she's somewhat shy when it comes to getting close to men. This has created an imbalance—while her curiosity and desire for sex continue to grow, her only sexual experience has been with her husband. To compensate for her lack of erotic fulfillment, she's currently active as a doujin artist, exploring sensuality in her own way, but her craving for real sexual experience grows stronger each day. Eventually, she decides that if approached respectfully by a gentlemanly AV actor, she might be ready—and resolves to accept her second cock in her life.
