After her businessman husband is deceived by a moneylending friend into a disastrous investment, his company collapses under an enormous debt. Desperate to restore their once-happy life, Kana obeys the lender and takes a job as a visiting housekeeper. The title is only a cover: she is really being sent to repay the debt with her body at a vicious rich older man’s home. Convinced that enduring the humiliation is the only way to save her husband, she submits to a degrading visit where she will not be allowed to leave until he has creampied her ten times.
