St. Madonna Hospital is renowned as a place dedicated to preserving precious human lives, yet within its walls, male and female desires run rampant. Dr. Reiko (Jun Kusanagi) dedicates her own body to training residents through hands-on instruction. Meanwhile, Mika (Misuzu Shiratori) and Kumiko (Maki Tomoda) spend their days relieving stress with cock. Long-term patient Tomoyo (Chisato Shoda), anxious about her extended stay, seeks emotional escape through affairs with doctors. Under the guise of special treatment, wild orgies erupt where soaking wet pussy is violently penetrated with cock injections. A powerhouse production featuring four stunning actresses delivering an intense, no-holds-barred performance set within the hospital.
