Rina, a high school girl from private K High, is an innocent and naive JK who knows nothing about the ways of the world. Under the pretext of a health examination, she's lured into a consultation room using an unusual pickup method that's gaining attention as an effective approach in today's society. Her fair skin and pink nipples make her the perfect representation of a desirable JK physique. Her slender frame and straightforward personality give off a student council president vibe. The examination covers every part of her body—mouth, tongue, breasts, pussy, and even her anus—causing her cheeks to flush deeper red with each passing moment. The way she looks at the doctor with teary eyes carries a strangely poignant atmosphere. She might even be slightly aroused. Riding that sensation, her mouth and pussy are filled with cock, and she goes at it fiercely, her delicate body trembling as if it might break. Shaking uncontrollably from the waves of first-time pleasure, she cums over and over. Finally, it ends with a creampie—the most beneficial for health and an effective measure against Japan's declining birthrate.
