In this adult school role-play, a delinquent girl advertises unlimited use of Yuria's mouth for just 500 yen. After fleeing a compensated-date scheme, Yuria is turned into a near-free subscription sex toy for the men in her class. Delinquents ram her throat in a bathroom, laugh, and photograph her gagging, drool-covered face. Even the teacher she expects to help uses her throat like a sex toy. The gangbang escalates until both her mouth and pussy are violated amid violent gagging sounds.
