Yes I'm a Doctor, I took a weekend Course

Poor johnny is a bit perplexed, laying naked on the medical bench with his feet in stirrups.  "This is weird, I've never been told to get in a position like this at a Doctors office before" he says just as the Doctor walks in.   Dr. Bella is wearing a mask and asks the patient what his problem is.  He says he is having ED problems and thinks it is as a result of blunt force trauma to his testicles.  The Doctor holds a stethoscope to his chest and says his heart seems to be racing.  "Well I'm a bit confused because...", the Doctor cuts him off and replies, "Confused, do you have a fever or is it just regular male confusion?"  He says he's just never been in a Doctors office like this before.  She removes her mask and the slaves eyes open and he asks her "Do you have a sister?"  She explains she is an only child and he then recognizes her as Lady Bellatrix the one who ball busted him yesterday.  Lady Bellatrix says he has been lured to this office because what he needs is a Dominatrix, not a Doctor.

She takes his balls into her hands and squeezes them and says she will be doing some medical experiments on him to see if they can cure his problem.  Bellatrix tells johnny she was concerned he might be tipped off by the unusual office but then realized he is just a dumb man and would probably just do as told.  She slaps his balls and twists his cock.  "Why are you even worried about getting an erection, anyway?" she asks him adding "No one cares about your erection."  She then reaches for a set of sounding devices and sets them on his stomach.  "I want you to put your concerns aside, I do have some medical education" she tells him, continuing "I took a weekend course a few weeks ago, I might have been a little drunk at the time, but you should be fine."  She then explains the main thing she learned was to just take a medal sounds and ram it up a slaves urethra.  "I find formal education to be a bit overrated", she continues.  Johnny groans in fear of what lies ahead.  After a good sounding, first with a small tool and then a bigger one, and stroking of his dick, his erectile dysfunction magically disappears.  Lady Bellatrix throws in talk of some gay activities like him being rented out to biker gangs or the male Doctor Julio coming in and having his way with him so maybe that was the cure, who knows.  "It is rather unconventional in a medical office but Dr. Julio and I have been fucking on our lunch break for years" she tells johnny.  As his treatment nears an end and an even bigger sound is inserted Bellatrix says in time she might be able to fist his urethra or just pull out his butt plug and stick that in his dick.  There will be no coming today though as she wants him to go from this treatment right to a gay sauna and suck off several guys to see how his cock reacts.  "Come back an hour early next week for your visit, with photos from tonight, you can wait in the waiting room", she says.  The camera zooms down to show there's a cage built into the bench aka the waiting room. Poor johnny!
