Schoolgirl SAKI was living an ordinary life focused on her studies when one day she was suddenly attacked and abducted by a group of men. Taken to an abandoned underground warehouse, she was hung up and left immobilized with fear. Her underwear pulled down, her genitals touched by the men, she fell into utter despair. Yet SAKI refused to give in. Attempting to resist with fierce determination, she was instead subjected to hellish torment with a vibrator. Her entire body tightly bound and strapped to a chair, she lost all freedom and was reduced to nothing more than a plaything for their pleasure. The transformation in SAKI's demeanor and emotions throughout this ordeal forms the core focus of this work.
