Adult student role-play. The second entry in Otona Teikoku's popular adult comic series receives a live-action adaptation. At a spring entrance ceremony, Shinya falls for his new classmate Sumire, a quiet adult student with a cute, delicate face and huge tits visible beneath her uniform. She barely reacts even when he touches her breasts and offers no resistance, marking the start of a new term in which he takes every liberty with her.
