No matter how much air I inhaled, it felt like oxygen wasn't getting into my lungs... Love, sex, worries about the future. My youth was filled with endless worries. You were always smiling, dazzling like Natsuzora... But I saw you once. You had a sad expression on your face in an empty classroom after school... "You look good with that ponytail" was the only thing I ever said to you. You loosened your lips and left with a smile. Back then, with the beautiful girl in uniform... During lunch break, the girl who fell asleep in the nurse's office... a daytime lewd crawl. After school, with that girl gazing at the school grounds... classroom sex.
