Starting with intense urges to pee, the girls are forced to hold it in front of an unmanned camera in this uniquely structured release. Under the rule that they can finally urinate when the timer goes off, they struggle desperately to endure. Each girl's reaction is different, showcasing their individual personalities in fascinating ways. When the timer finally rings, a new one appears (+16 minutes), but unaware of this extension, they continue holding as before. Their shocked reactions upon discovering the new timer are striking and make for compelling viewing—just as they begin to relax, they're once again forced to endure, cursing their fate. Those who successfully hold are measured for urine output, with bladder distension also recorded. In this installment, three girls ended up accidentally peeing themselves. Excretion House.
