Dr. Aoi, a skilled internal medicine doctor known for her mental care and trusted by her colleagues, finds herself under scrutiny from some patients. By nightfall, she transforms into a lustful nurse who visits hospital rooms seeking young men's cocks to satisfy her insatiable desires. Her actions are crude and depraved, leaving victims either riding rough cowgirl positions or shooting their loads through intense sucking blowjobs... Tonight, once again, her footsteps echo throughout the ward as she seeks new prey.

患者に寄り添いながら精神的なケアをこなし、同僚医師たちの信頼も厚い有能な内科医の葵。しかし一部の患者からは警戒の目で見られている。彼女は深夜になると病室を訪れ、若い男たちのチンポを貪る痴女医に変貌していた。昼間の医者と同一人物とは思えぬ、下品でエグい責めの数々。ある者は強●勃起させられて強引な騎乗位で果て、ある者は強烈な吸引フェラで大量に射精させられる…。今夜も彼女の足音が、病棟内に響きわたる。
