Okay, pretty long list but any or all of the following:

>Old Doctor. Maybe have another one in the room to humiliate her more. The older the doctor the better. I think its great when the doctor is trying hard not to get aroused but can't help it. I love when his hands shake and he stutters a bit. Make even comical. The doctor should also laugh evil-ly and moan more.
> School girl outfits. Very embarassed to undress. Begging and pleading / humiliation. Threats to call home if she doesn't comply with all commands
> Focus on patient slowly undressing while doctor watches - laughs pervertedly and makes comments
> Large natural breasts (DD+). The doctor should force her to jiggle and bounce them. More movement under the guise of medical "tests"
> tickling in exam - especially breasts and ass
> spanking in exam
> Foot licking - licking everywhere
> Blowjobs / ream jobs on the doctor

Themes:
> prison theme exam / Old German SS?
> one where the girl has a fetish for dirty old men and actually tries to turn him on and he tries to maintain his composure
> grandfather in the room during exam getting off on the exam and maybe assisting, maybe he spanks her when she doesn't obey doctor's orders
> hypnosis
