The Beautiful Butt Komachi Contest is held every year in a small town. The 6th winner, Miou, is the woman Shota, a butt-loving boy, admires. One day, Shota meets Miou by chance and gets her autograph. He's so happy that he follows her and finds out her address. He then breaks in... and using his privilege as a Ko○mo, he gets carried away and starts playing pranks! His dick can't stop getting horny at her firm, thick butt that even Ko○mo finds fascinating!
