Mutsumi Matsuoka, a 44-year-old woman who supports her family as a part-time knitter. She gives off a pure and innocent vibe, and for good reason. Her life has been largely devoid of sexual experiences. She remained a virgin until she met her husband at the age of 27. After their marriage and subsequent pregnancy, their intimate life came to a standstill. She has never cheated and her total number of sexual encounters is a mere five. After 16 years of abstinence, she finds herself in her mid-40s, blissfully unaware of the pleasures of a man's cock. Driven by the desire not to end her life as a woman, she decides to make her debut in the adult film industry. This nearly virginal wife embarks on her first grand adventure to discover the joys of womanhood.
