Yamada is hospitalized after breaking both of his hands. He has a "chronic disease" that causes severe pain in his testicles if he does not ejaculate at least once every three hours. While in the hospital, he is unable to use his hands and the nurses in the ward are in charge of his "treatment". However, this hospital is rumored to be a hellish place with nurses of the worst character...! The second nurse with the worst personality is the insidious nurse, Krokawa. Yamada is asked for his "sincerity" in return for the sperming treatment and he is undeniably used for Krokawa's nasty revenge act. Yamada is squeezed by a masturbator-mounted dick and ejaculates a lot inside Tachibana's private locker. Kurokawa treats Yamada, who has fallen as far as he has fallen, as a "scab buddy". "I wonder if 'scumbag pervert dick' and 'scumbag pussy' go together...?"
