Kanata, a nurse with a youthful face and a petite figure, is secretly seducing married patients in the late-night ward, increasing her pool of adulterous partners. Whenever a new patient arrives, she checks if they're married or have a big cock, then uses the guise of a diagnosis to give them a suggestive examination, leading to forbidden encounters. Despite her innocent appearance, her 170cm tall frame allows her to dominate and devour these men with her insatiable lust, engaging in passionate, uninhibited sex with them.
