A well-behaved girl who never utters a word, wouldn't she be completely compliant to whatever the teacher does? Even when the shy library committee member is violated by the teacher, she still experiences multiple orgasms. (SONE-411)

A bookworm, always alone at school, a girl with a heart always in the library. One day, she had a lewd fantasy about the teacher's lewd gaze. When they were alone in the library, the teacher suddenly attacked her. Although she resisted slightly, she was still violated. She couldn't forget the pleasure she felt then, and when she called out to the teacher, she kissed him willingly. From then on, the middle-aged teacher and the timid female student began a despicable sexual relationship.
