This live-action adaptation of Tokumori Hanten’s popular 55,000-copy story follows a woman who was raised in sexual slavery and can only find value in making men ejaculate. After buying her freedom partly out of pity and partly because he needs help at home, a man begins living with her. She clumsily tries to repay him with the only skills she knows, relentlessly arousing and draining him despite his reluctance. As they share a home and she encounters genuine kindness, she gradually begins to see herself as a person rather than a tool, even while leaving him emptied night after night.
