Desperate to restore their old life, his wife decides that she alone will endure the consequences and obeys the moneylender's order to surrender her body. Thus begins a degrading two-day hot-spring trip where a cruel, insatiable man treats her as a compliant human sex toy and repeatedly creampies her, refusing to stop until she is pregnant.
