[NippatsuKokuhou (Kaneko Ken)] Peeking girls at boy's restrooms

Schoolgirls have found the perfect vantage point through the gaps of the boys' restroom, and they waste no time putting it to use—giggling as they watch their classmates pee, then trading gossip about who measured up and who fell hilariously short. One unlucky boy becomes their favorite subject, his tiny, foreskin-buried equipment dissected in merciless detail beside a well-hung classmate's far more impressive specimen, all while the girls insist it's just 'a learning experience.' Curious, cruel, and completely shameless, these peeking girls turn an ordinary trip to the urinal into a gauntlet of pure embarrassment.
