Yukah, a serious female college student, was not satisfied with sex, but then an event occurred that shattered her values about sex. Akikawa, a friend of her father who had been her tutor when she was young, got drunk and attacked Yuka, who was growing into an adult's body.

From that day on, she became hypersensitive, aroused just by seeing older men.
