Shion, a student at a prestigious girls' academy, was raised as a pampered daughter in a wealthy family, lacking nothing in life. However, after her father's business collapses and he falls into debt with loan sharks, a corrupt lender sees an opportunity. Learning the family has no money left, he sets his sights on Shion's young, well-developed busty body as collateral. Tightly bound with hemp rope, her swollen breasts constricted, Shion endures cruel, degrading torture, shedding tears of despair. The pure, innocent young lady falls under the control of beasts, her big breasts trembling with each movement—a true embodiment of the aesthetics of destruction.
