Bank clerk Arisa overhears a conversation one day between her branch manager and a man who was denied a loan. Eavesdropping, she realizes the manager is involved in a secret money deal with the man. To silence her, she is gagged and forcibly silenced on the spot. One month later, armed men storm the bank, taking hostages. In exchange for their release, they demand Arisa perform degrading acts. Forced to sink her hips onto their fingers and made to move against her will, Arisa reaches climax. In the end, a chaotic gangbang ensues, culminating in consecutive creampie orgasms from all of them.
