When I was a first-year high school student, I had my first experience with an upperclassman from the track team. After practice ended, we kissed in the empty club room, then lay together on the floor and had sex. It hurt a little since it was my first time, but I was really happy. Though I was nervous and anxious at first, feeling his warmth made me genuinely enjoy every moment. That unforgettable instant still remains vivid in my heart.
