Miu's happy engagement is shattered when her older boss imprisons her in his foul-smelling trash-filled room. Restrained and exposed on filthy bedding, she tearfully begs him to stop, but he ignores every refusal and pounds her mercilessly with his dirty cock. Her resistance gradually fades as she begins responding to sensations her fiancé's gentle sex never gave her—the brutal mating that reaches deep inside her. Repeated violent creampies leave her mind melting with pleasure until she says she may be happier this way. Dressed in a uniform and ordered to serve, she ultimately chooses life as his captive sex toy, conquered by pleasure into complete obedience.
