Yumeko Jabami, a tight-assed high school student, loses a bet to a gang of perverted delinquents. As punishment, she is forced to perform various degrading acts, including sucking their cocks and spreading her legs for rough sex. Her virgin pussy is brutally penetrated by huge cocks, causing her intense pain but also an unexpected pleasure. The delinquents take turns fucking her tight hole until they are all satisfied, leaving her covered in cum and begging for more. Finally, one of them shoots his load deep inside her womb, causing a messy creampie. Exhausted and humiliated, Yumeko is left sobbing as the delinquents laugh and walk away.
