My beloved mother is having an affair. After witnessing a shocking scene that cannot be explained away, what was born inside Daisuke's heart was not anger or sadness, but a dark sense of possessiveness. A violent crime committed in order to make the mother his own. Strangulation, Irama, and forceful insemination. The mother, dominated by irresistible pleasure, finally begins to automatically convert even pain into pleasure... Before I knew it, I had been reborn as a fine Onapet.
