Well, it's your first time and I hope you're ready for your medical exam today, it is vital we give you an anal probe to make sure everything is functioning properly in your rectal area! Please just remove your clothes, and you will need to have your anus facing us so we are able to probe. I'm going to bring in my lovely assistants too to help out. You do seem to be enjoying it a bit too much though, I'd like to remind you you're here for your medical check not your own enjoyment.
