To be honest, I was shocked by the intensity of this woman's sexual desire. Contrary to the image of an older "aunt" figure, she had a masochistic side and always obediently followed my instructions. Our relationship continued even after I entered school, and she always prioritized me. Before she got married, we frequently met at friends' houses, or went out together, spending time at my place or love hotels. We saw each other as naturally as any regular couple. I took this relationship for granted—until one day, a sudden event occurred, and everything changed.
