The first time I met her, I thought she might be a new type of paid escort. But she was surprisingly cute, and realizing I might never get another chance to be with a real schoolgirl, I decided to spend the night with her at a hotel. However, by morning, she had vanished without a trace. A few days later, I ran into her again by chance—but this time her appearance was completely different. She wore a neat three-braided sailor uniform with black tights, looking utterly innocent and pure. Yet her true nature soon revealed itself: she was an extreme masochist. Despite her serious demeanor, she moaned, "Ah~ I'm cumming again... It's okay... Don't hold back, creampie me..." The stark contrast between her prim appearance and her filthy talk became the most arousing trait, making her charm all the more irresistible.
