New nurse Yui Tenma is a clumsy girl who doesn't seem particularly competent at her job. Yet, surprisingly, she enjoys immense popularity among male patients. The secret lies in her absolutely erotic and cute body, and her special care techniques designed to pleasure patients. During meal assistance, she feeds patients mouth-to-mouth, turning it into passionate kissing that excites them—leading inevitably to sex as her "responsibility." When aroused during duty, she relieves her own cravings with squirting masturbation in the examination room. For insomniac patients, she provides handjob and blowjob treatments to help them reach a peaceful, sage-like calm. To entertain bored patients, she suggests king's game, happily obeying commands that lead to tit exposure, anal inspection, and toy play. When perverted patients come to the nurse station, she handles them with aggressive female-led sex. No matter where she is, Yui's presence always draws attention.
