Aika works in the audit department of a pharmaceutical company and discovers a serious mistake made by her husband in development. While trying to keep it from becoming a scandal, she is exploited by a vile boss who once wanted her and is drugged with aphrodisiacs. Her body is altered into a state of extreme sensitivity where even a touch arouses her, yet love for her husband keeps her enduring the abuse without surrendering her heart. But the boss alternates slow, relentless teasing with brutal attacks until she passes her limit, leaving her entire body so hypersensitive that every inch feels even more responsive than her clitoris.
