A happy marriage collapses when the husband's trusted moneylender friend betrays him, burying his company in debt and forcing it into bankruptcy. Desperate to restore their life, Ikumi secretly meets the lender. He tells her that if she wants her husband saved, she must become his woman every weekend. Believing she can endure anything for the man she loves, she offers her body, beginning a humiliating series of weekends in which the insatiable older man repeatedly creampies her and refuses to stop until she becomes pregnant.
