From a play doctor/fantasy perspective…
I think it’s about both control and exposure.
When she’s laying there, posed in such a vulnerable position, presenting herself for me to do as I will. Already she’s exposed, but the speculum takes it to a new level. Not only is she now even more vulnerable, being held open, but the act of opening the speculum exposes her very most intimate place, a place visible only to her doctor.
And the control aspect is important as well. It’s up to me, as the doctor, to choose how gently - or not - I insert it. Do I insert it slow and smooth, angled down, make it as easy as possible? Do I speed it up, possibly triggering those muscle contractions? Do I aim it a bit higher so it scrapes against her anterior wall and those sensitive places, her g-spot, her urethra? Has she been a good girl, or a difficult patient? It’s all in my control, do I open it just wide enough, or shall we see just how wide it goes? I’m finished now, or am I? It’s only been stretching her a few minutes, maybe I’ll leave it wide open for a while longer while I prepare my instruments or whatever I need for the next part of her exam.
(Of course, this is all under the guise of fantasy and isn’t meant to be anything besides the idea of dominance and control applied to medfet! Always play safely and with consent!)
