Himari neesan, the girl next door I used to know, returned to our rural hometown after a long absence, now with a slightly gyaru style. At first, I was taken aback by how much her appearance had changed, but my heart started pounding as I realized she'd matured into a stunning, elegant woman. When she found out I was still a cherry boy, she treated me kindly just like she used to, began talking about sex, and even taught me about it. Through these experiences, I had my first unforgettable encounter—an extraordinary moment I'll never forget.
