Needing a housekeeper for his brother Ginji, who was injured in an accident, younger brother Natsuya hires a maid. The woman who arrives, Yumi, is a sweet, somewhat clingy, and irresistibly sexy beauty. Ginji quickly succumbs to temptation, restraining and toying with her as his uncontrollable desires take over. Yumi offers no resistance, surrendering completely to his lust. When Natsuya discovers what's happening, he too joins in, the brothers competing for Yumi's voluptuous body. Again and again, she is taken before both men, yet her face shows no sign of pain—only a subtle, intoxicating pleasure that only heightens their arousal.
