Kimajime na Yuutousei wa, Sensei dake no Mesu ni Naritai.

Takako Fujii is the pride of the school's kendo club—a brilliant, tall, and strikingly beautiful student admired by her peers for her cool demeanor. To her coach, however, she is simply a dedicated and endearing pupil. That perception shatters when Fujii privately confesses her romantic feelings for him. Knowing that a relationship between a teacher and student is strictly forbidden, he devises a misguided plan to discourage her without causing emotional harm. He shows her explicit adult videos, hoping the shock will make her abandon her infatuation. When she abruptly flees, he believes his strategy has worked. Anxious about potential harassment accusations, he is stunned when Fujii summons him again the very next day. Instead of anger, he finds her waiting in an empty classroom, calmly removing her uniform to reveal provocative lingerie modeled after the actresses from the video. She declares her determination to become exactly the kind of woman he desires. Overwhelmed by her earnest devotion and unable to resist, their encounter quickly escalates into a forceful and intense sexual experience. Yet Fujii remains entirely undeterred, continuing to seduce him with growing boldness until he finally surrenders completely to her passionate affection and alluring body.
