Younger than me at the time, her sexual desire during this period far exceeded my imagination. She had a submissive personality and obediently followed every word I said. Our relationship continued even after I advanced to higher education; before she got married, we frequently met at friends' houses. We regularly went out together, and she actively came to see me at my place or at love hotels. We built our relationship naturally, just like an ordinary couple. Back then, I was innocent and simply enjoyed everything without thinking. But one day, a major incident suddenly occurred.
