A specially modified public toilet is secretly installed in a hidden location, disguised to appear as if no toilet exists there! When amateur gyaru girls sneak in, thinking they're alone, they're ambushed with mischievous pranks. Unaware of the hidden cameras, bikini-clad girls expose themselves while changing clothes, urinating, or removing body hair—moments meant to be private. The moment they sit on the toilet, special mechanisms activate, completely sealing off any escape route. Watch as hands, vibrators, and even a cock emerge from inside the toilet and from within the walls, tormenting the screaming, crying girls.
