A predatory, big-titted proctologist believes any man who cannot cum anally needs to be remade, body and mind. Her patient undergoes a humiliating first anal display, an enema stay with rimming, fingering, and handjobs, then careful anal stretching with manual and powered tools. After enduring the daily exams, he receives upside-down handjobs and creampie sex. Finally, the doctor gives her chosen patient an exclusive strap-on examination, repeatedly penetrating his ass until he drools, makes a helpless orgasm face, and becomes her obedient pet.
