A childhood classmate who once mocked her small breasts is admitted to the hospital, and the now-busty, dominant nurse begins five days of revenge. He initially thinks his fantasy has come true, but her edging cowgirl rides and cruel ejaculation-control games turn it into a nightmare. She repeatedly gets his pathetic cock hard, takes it bare, and stops just before release, leaving him in agony. No creampie sex is allowed until his cock is completely broken—this nurse is no angel in white, but an irresistible little devil.
