My neighbor, Himari nee-san, had always been kind and taken care of me. Growing up in a single-parent household, she was a pillar of emotional support. Back in school days, whenever my parents came home late, I'd wait for Himari nee-san to come stay over. She was mature, gentle, and thoughtful—someone I deeply relied on during adolescence. But gradually, her increasingly womanly presence began stirring unfamiliar feelings inside me. Today, once again, my mom was coming home late, so Himari nee-san was due to visit. She always flaunted her big ass, teasing me without mercy. In the time spent with this older school girl, my virginity was easily taken. I touched every part of her body and experienced sex for the first time. Now I had something to brag about at school. This first experience with an older JK was a major milestone in my life.
