A pure and innocent-looking high school girl, Kana, works part-time at a library. Despite her intellectual aura, she has a slightly sadistic inner self. She targets a middle-aged university professor, seduces him, and thoroughly serves him. She gives him a passionate blowjob, not letting a single drop of semen escape, and squeezes out his semen with her pussy. Restraining the middle-aged man and playing with him as she pleases is Kana's joy.
