One of my first jobs as a doctor was working at the County Hospital, and being assigned wherever they needed someone that day.
I got assigned to the GYN clinic a lot, and eventually learned it was because most of the staff were MALE (like me) and most of them did not want to work in that clinic - because their wives believed the patients were almost all hookers. There were a lot of hookers, but mostly "call girls" who were prostitutes that had regular clients and actually had a list of contact info in case they ever got an STD, which did happen but not as much as I would have thought.
After a few weeks of examining and treating women with gonorrhea and trichomonas (pronounced TRICK in slang talk), I realized that I could actually differentiate the microscopic diagnosis by smelling the sick cunt up close.
I started tasting the cunts that did not smell sick- especially the ones that smelled SEXY. I have always had a good sense of smell, and the smell of healthy pussy has always been a huge turn-on for me.
Although I started by "tasting" my fingers, which were in rubber gloves, I eventually decided that tasting "the source" made a lot more sense. For one thing it was a lot sexier for me to get right down in her cunt, and it was rewarding to hear most of the women sigh and quiver as my tongue ran up their vagina, labia and clitoris.
Of course I would warn them first that I was taking a sample of their vaginal secretions - which I was doing! And I would always ask "did that hurt?" and enjoyed the fact that although about half just said "No", the other half would say, "Not at all, it actually felt really good... can you do that again?"
I never had any of them "complain" - even though I am certain that they realized that was my tongue. I was hidden behind the sheet that draped over their raised spread knees, and had my left hand pressing on that side of the vulva to steady my head so that ONLY my tongue made contact with the vulva, not my chin or forehead- which might have allowed women to know that my face was right up in her pussy. And I did not let my warm breath be a giveaway either.
I realize there was a risk of infection- but actually not very much because I smelled the disease in almost ever case- and did not lick sick pussys. Eventually I realized that there were distinct differences in how pussy tastes- all separate from the different smells. Please realize that a woman who has terrible hygiene will contaminate her own cunt with feces when wiping, or allowing sex partners to use her asshole then switch to her cunt...
I did not bother with tasting those because I could already smell the shit.
Now that you know about my nasty ethics, you can understand what my STORY is about. One of the nurses in the GYN clinic, who knew that I am married, managed to look in on me while performing a pelvic exam- and she had looked from the adjacent area, not from behind me... so she could see my face right up in that pussy, and probably saw my tongue work up across the clit.
