25-year-old K from Osaka, previously married with no children. Her experience with men has been extremely limited, and she was deeply unsatisfied with her sex life during marriage. She particularly complained about sex being nothing more than "just penetration" and was highly dissatisfied with her husband's small penis size. Gentle and composed by nature, she speaks softly, but has the unusual trait of letting out an abnormally high-pitched voice when reaching orgasm. This video features a total of five married women including her, each possessing unique charm and individuality.
