After taking a suspicious penis enlargement supplement online, a man finds himself with a non-stop erection. Rushed to the hospital, he's shocked to discover that his attending physician is Aya, his ex-girlfriend with whom he shared incredible physical chemistry. Despite her initial tsundere demeanor, claiming it's "just treatment" as she performs manual release, Aya's own desires are evident from her increasingly aroused state due to continuous night shifts. He begins to secretly call her away to the large ward and examination room at night, where their hidden encounters escalate. Initially reluctant, Aya gradually transforms into a sexual monster, leading to intense, all-night sessions. Being constantly pleasured by his ex-girlfriend, with whom he has perfect chemistry, proves to be an unparalleled experience.
