The private rooms in the girls' school toilet are full! A record of 55 JKs who couldn't hold it in right in front of the toilet and urinated in large quantities! "Oh... I can't take it anymore... It's coming out..." The schoolgirls, whose bladders have burst, squirt large amounts of urine with both legs shaking! Once it starts, the toilet is flooded with JK's holy water that can't be stopped! Is it a coincidence? Is it a prank? A lot of footage of incontinent schoolgirls captured by a high-performance hidden camera is included!
