Spending time on the school rooftop became an extraordinary experience unlike my usual daily routine. With the strong wind blowing, my skirt flapped wide open, giving me a close-up view of Yumi Nijimura, a girl from another class standing right beside me. The moment I saw her panties clearly, I felt an unprecedented thrill. Supported by adult strength, I was able to enjoy the real sight up close—an incredibly irresistible experience. Still, I can't believe I'm only twenty years old and already felt such intense excitement; even now, I'm completely satisfied. I'm actually a little anxious about what could possibly surpass this experience in the future.
