A happy marriage collapses when the husband’s trusted moneylender friend betrays him, leaves him buried in debt, and drives his company into bankruptcy. Desperate to restore their former life, Mahiro secretly meets the lender. He demands that she become his woman every weekend if she wants her husband saved. Believing she can endure anything for the man she loves, she offers her body and begins a cycle of degrading weekends as his substitute sex slave, repeatedly creampied until pregnancy.
