Sumi Kurokawa, the homeroom teacher, had always been a serious and kind presence. But recently, I became aware of the allure of her hips, stirring hidden emotions within me. The class trip became the turning point—her usual calm demeanor vanished as she began seducing me, repeatedly grinding her hips against me. Over the course of three days, she made me creampie her again and again, a desire that refused to subside. Caught in the complex roles of teacher and student, and her being a married woman, the intense emotions of adolescence surged, creating an unforgettable, heart-racing experience.
