Project two of verifying whether women really lose bladder control easily! A hands-on production focusing on whether urine leaks when sneezing while holding in pee as tightly as possible. The results are shocking and yield incredibly interesting discoveries. As Koyori uses a tissue to trigger a sneeze, her beautiful face contorts like a gag manga character, drooling "hebu-shi" while liquid sprays out from her urethra, soaking her underwear. The urine spurts out with a splash, drips down slowly—each leakage different, all depicted with striking realism. As the urge grows harder to bear, some girls end up fully wetting themselves, others leak freely even before sneezing, eventually losing sight of the experiment's original purpose. Thus, a crazy work testing "mild incontinence" is completed! An idol-level older woman. After some introductory talk about sneezing, she straddles the chair and the test begins! Unable to sneeze on command, she struggles intensely, yet unleashes surprisingly loud, powerful sneezes that contrast sharply with her appearance. At that moment, what happens to her crotch!? Ms. Rin ends up urinating during her sneeze—exactly the opposite of the intended test. She herself sadly explains the reason why. A perky, intelligent office lady. Despite her intellect, she opens her mouth blankly and unleashes violent sneezes. With each one, the stain on her crotch spreads wider, eventually running down the chair... A busty, seductive beauty resembling Aya○. As her drool-inducing, forceful sneezes continue, the wet stain creeps from her crotch to her back and entire body, spreading until it forms a puddle beneath her, overflowing from the chair!?
