Tenma is an outstanding female student in the class with excellent academic achievements plus a hot body, so she is loved by almost everyone, especially male students and volleyball teachers. One time, when she was changing clothes in her room, she accidentally saw the volleyball teacher standing right outside the door. He scolded her for being bad at her subject and asked her to go to a private room to practice again. Tenma didn't know what else to do but follow, practicing with him while making sensitive movements touching her body, until she couldn't stand it anymore and was unable to resist the teacher's strength. That damn teacher. He raped Nakano mercilessly.
