Himari's older sister, who used to live in the neighborhood, became a little gal and returned to the countryside for the first time in a long time. - Her appearance has changed so much that she was confused at first, but more than that, she was thrilled that she had become a beautiful adult woman. When Himari's sister found out that I was still a virgin, she was gentle like she used to be and taught me various naughty things. It was a first experience that I will never forget.
