Saori Fujimori, who graduated from university this year, dreams of becoming an elementary school teacher next year. At just 20 years old, she is pure and serious by nature. She has had only one boyfriend in the past, with whom she experienced foreplay but never intercourse. After their breakup, she continued to feel a desire to have sex, but her earnest personality prevented her from taking the step. Now on the verge of starting her career, she strongly feels the need to experience it once more—and expresses her wish to lose her virginity in an AV. Despite her tense and stiff expression at first, she successfully loses her virginity and gradually begins to show a more sensual side. Mixed emotions of pain and the novelty of first-time experiences bring tears to her eyes—not from regret, but from joy. She also discovers pleasure through using a sex toy for the first time, meeting a new side of herself through these various experiences.
