This summer was so hot... When I returned to my hometown for the first time in a long while, the one who greeted me was Saki-oneechan, who lives next door. She had transformed from the girl I used to play with as a child into a mature, alluring woman. As we reminisced about the past and played with hand-clapping songs, I, who had touched Saki-oneechan's body, could no longer hold back and unconsciously hugged her tightly.
