Kuriyama Rio plays a beloved wife who is offered to her ruthless boss for a "one-month rental." Amid a power dynamic where she cannot refuse, her boss repeatedly violates her relentlessly every night. At first, she sheds tears thinking of her husband, but as his virile thrusts consume her reason, she gradually opens her legs and yearns for creampies. Only uncensored footage can capture the vividness of the process as her dignity is dismantled by the defilement and she is reduced to a "shared urinal." The expression on her face as she chews on another man's seed in her womb, away from her husband, is the height of immorality. Over the course of a month, she is completely remade.
