Hina joins a company as a new employee, the only female among male staff. Desperate for money to protect her younger brother, she borrows 5 million yen without collateral. As repayment, she is trapped in a setup rape scheme, her delicate body impaled by an extremely thick cock, crying out in pain and tears. Forced blowjobs and consecutive rapes follow, culminating in 20 consecutive creampie orgasms, turning the company welcome party into a destructive finale.
