[Toufu Majin] Kukkiri! Washinren [Machine Translated]

A summer outing goes hilariously off-script when Mukogawa admits she forgot her underwear at home, treating her classmates to an unobstructed view of her crisp tan lines and bare bottom every time her sundress flutters up. Curious Hirota-kun crouches in for a wide-eyed inspection of everything down there, marveling at the view until the bulge in his shorts betrays him and turns him into the one being teased. What starts as accidental exposure snowballs into a dare-tinged invitation to see even more, closing on giggly bickering over whether his pee-pee is standing up again.
