Sounds like a Crime Investigation Lab.
Donīt leave your fluids - they are on to you.
The most exciting thing ever asked of me in my line of work was in med school. We were teached how to perform a rectoscopy - basically putting a short pipe up the arse to have a peak whats going on up there. We are a dozen pupils mixed gender. The doc asks us to team up in pairs. I got lucky, hooked up with a lovely brunette. My pal didnīt. He got a nerdy looking guy that ended up throwing up during the procedure.
I made a total idiot out of myself. Nervous and shaky - brunette on all four. Managed to enter her rectum rather smoothly. She jerked a bit but didnīt say anything. So then its her turn. Very smooth. With the rectoscop safely tucked up my arse, she asks if I am alright. I go - thank you it feels just fine... duh.
You wanna hear the story from when we trained to perform vaginal examinations in group with young women hired by the University to let us train on them..?
