I have always had a fetish of a Nurse seeing me nude, maybe because it is probably the safest place to be exposed.
Public streets or places like that can mean a jail sentence.
So, I go get checked out a lot, but most are rather careful, I suspect they have seen a few guys like me before.
Recently I went to the Urology clinic out in the valley, the complaint was a burning sensation when I took a pee. Without fail, that one gets them to take a look at least.
Sure enough, first it was give them a sample in the little room, then they took me to a small office and handed me a gown. In came this Nurse, followed by what I guess is her intern, that one looked to be about 20, the Nurse easily 40 or so.
The nurse checked me, actually pulled back my foreskin, and took her sweet time as I stood her holding the gown up. Then she told the intern to get a sample, the intern came over and used a Q-tip, pushed it in the end of my dick while holding me with the other hand, by then I was 90% erect.
She giggled, then said that "This is sure easier when they are firm like this."
Then she gave me a little squeeze, winked, and they left.
