A literature-loving girl working at a university library appears plain and demure at first glance, but beneath her modest exterior lies a deeply impulsive nature. She visits the home of her beloved elderly professor under the pretense of studying rare, hard-to-find books, but her true intention is what lies deep within the professor's body. When the professor confesses his love, she strips naked before him, visibly flustered, and begins to seduce him. Though he struggles with the ethics of engaging with a student, he cannot resist her advances. The girl transforms into a snake-like seductress, stripping his clothes and taking his cock into her mouth. The professor's rationality dissolves as she engulfs his cock with her wet pussy, riding him wildly despite his age. Overcome by her youthful lust, the professor exerts himself to the fullest, eventually filling her young pussy with his sperm. The next day, the literature girl returns to the professor, seemingly embarrassed, and passionately declares her intense love for him.
