There was a tradition in that club of thoroughly violating female members and turning them into sex slaves. A new member, An, is bound and repeatedly violated almost every day. In the sports storage room, she is tied up, stripped naked, and humiliated. Unable to refuse the abuse from the coach and seniors. An cannot confide in anyone and endures in silence. "I can't take it anymore..." Eventually, even the newcomers violate An, and her hellish days continue endlessly.
