A story centered around urination while wearing diapers. This film portrays the real-life experiences of four women facing embarrassing situations in public—such as in movie theaters, elevators, trains, and restrooms—where urinating or wetting themselves is strictly forbidden. Thanks to wearing diapers, they miraculously avoid disaster. The video captures their realistic struggles of holding in urine, the squishy swelling of diapers absorbing urine, and the secret thrill and humiliation of discreetly peeing in public. Four women who successfully avoid accidents all think, "Thank goodness I was wearing a diaper!" [Elevator Episode 1] A woman feels relieved when she notices a fellow passenger has a diaper, but fails to put it on properly, causing urine to leak out through gaps. [Movie Theater Episode] A bladder-sensitive gyaru changes into a diaper before taking her seat, but the volume of urine exceeds capacity, soaking through and wetting the seat. [Elevator Episode 2] A woman narrowly avoids incontinence during a trip by using a portable diaper—raising the question: why carry one? Could it be she still wets the bed? [Train Episode] A beautiful woman rides a quiet train, her diaper swollen to the brink of bursting, yet she exits without anyone discovering her secret.
