My gifted student, Miyu Aizawa, lost her parents in a tragic accident. The shock of seeing their altered state caused her to lose her memories, and her cognitive functions regressed to a childish level. Yes, it was "age regression." I had heard of it, but I never expected to see it in person. With no other relatives, I, her homeroom teacher, had to take care of her for a while. There was no trace left of the honor student she once was; she would crawl around with her bare ass exposed, moving wherever she pleased and wetting herself anywhere. Even though I knew it was absolutely wrong, it didn't take long for my reason to crumble before her cute face and erotic big ass. In this ultimate act of immoral sex, I couldn't stop my hips from pounding.
