Mari is 33 years old. She has been married for 8 years. During her student days, she was shy and had an interest in sexual things but generally belonged to the serious group. Her first experience was in the summer of her freshman year of college. After marriage, she hasn't been blessed with children, which has made her dislike having sex with her husband, and recently she's been feeling unenthusiastic. Now that she's over 30, she wants to try various experiences... but it's just a growing desire.
