First week of April. A young lady who just graduated from high school in Ikebukuro and is out in her "last uniform" during spring break is approached by a fashion magazine and asked to answer a questionnaire for a sex feature. In the Mirror Van, a real esthetician demonstrates a "ball pack" by saying, "Doesn't a penis smell? 80% of this smell comes from the balls." The innocent girl is shy but her eyes are glued to the stiff, erect adult dick, so she whispers, "Would you like to try it?" and lets him touch her balls... Will the heat of the dick stimulate her lust hormones and even allow her to have creampie sex?
