To raise money for filming a gang rape video, the voluptuous, busty office lady Hamabe Shiori (GVH-691) stripped naked.

The seemingly gentle and unassuming office lady, Shiori, is dragged to a bar by her friends, but becomes infatuated with the handsome waiter, Yuuji, and gradually starts going to the bar alone. With a meager income, Shiori even cancels her fixed-term deposit to continue going to the bar, only to find herself burdened with insurmountable debt… She is forced to engage in public sex amidst the insults of other men, and all her actions are filmed, turning her into a pitiful, impoverished office lady, used as a sex slave.
