A male secretly gives a diuretic to a female student he found in the park after school. Driven by an urgent need to urinate, she heads to the toilet but finds it unusable! Reluctantly, she moves to some bushes to relieve herself when suddenly, her vagina is exposed and immobilized!! Unable to move, she desperately tries to hold it in! But resistance is futile as her face flushes red with shame and she humiliatingly wets herself! Her sanity shatters as she repeatedly spreads the ecstasy and goes mad!!!
