[ROYD-093] I was seduced by my older sister who became a gal and had an erection. Himari Kinoshita (Censored)

Himari-neechan, who used to live in the neighborhood, became a little gal and came back to the countryside for the first time in a while. The appearance has changed so much that I was confused at first, but I'm thrilled that I've become a beautiful adult woman. When Himari-neechan knew that I was still a virgin, she taught me a lot of naughty things like in the past. It was my first experience that I will never forget.
