At the prestigious St. Brunhilde Academy, an elite cadre of female knights upholds a strict code of purity and discipline. Their world is turned upside down by the arrival of the 'Junpaku no Panty'—cursed white panties that, once worn, unlock immense power at the cost of the wearer's sexual inhibition. The series follows these once-chaste warriors as they succumb to overwhelming lust. Each episode explores a new girl's corruption, showcasing explicit scenes of frantic masturbation as they discover their own bodies, followed by intense, sweat-drenched lesbian orgies with their fellow knights. The panties force them into a state of perpetual heat, leading to graphic scenes where they fuck each other's cunts with their fingers, scissor until they scream with pleasure, and eagerly lick the dripping juices from one another's thighs. The plot revels in their transformation from noble knights to insatiable nymphos, documenting their descent into pure carnal debauchery, with every scene animated inloving detail to capture their ecstatic, cum-smeared faces and writhing bodies.
