Early April. A girl who just graduated from high school in Ikebukuro and is spending her spring break out in her "last uniform" is picked up with "Would you mind answering a survey for a sex feature in a fashion magazine?" In the car, she is told "Doesn't a penis smell? 80% of this smell comes from the testicles," and a real esthetician demonstrates a "testicle pack." With a huge, fully erect adult penis, the shy, innocent girl's eyes are glued to it, and she is whispered "Want to try it?" and allowed to touch the testicles... Will she allow herself to be stimulated by the heat of the penis, causing her to be in heat, and even agree to unprotected sex?
