I've always had the fantasy of a doctor walking in, while i'm nude with my ass in the air.
He first inserts a thermometer into my rectum to record my temperature. While the thermometer is working, he reaches down to my penis, and grasps it, pointing it into a cup, instructing me to urinate so that he can collect a urine sample, while my ass is still in the air.
After i embarassingly urinate into the cup, he sets it aside, and retrieve the thermometer from inside me. He says I'm running a fever, and proceeds to probe me with his fingers, to check for any impacted stools. He proceeds to inform me that I need an enema.
After he lubes me and inserts the hose, and begins the enema, he begins to examine my testicles, and then proceeds to rub oil over my body, while I am still on all fours, with my ass in the air, water flowing into me.
His hands glide under me, rubbing oil on my belly as he gently squeezes me, as my tummy grows larger.
Once the bag empties, he removes the hose from inside me, and plugs me, telling me I must hold it for 10-15 minutes.
As I struggle to hold it, he grasps my penis again, and proceeds to milk me for a semen sample, in my embarrassing, vulnerable position. After collecting the sample, he guides me to the restroom, and removes the plug, allowing me to release.
After another enema or two, until I'm "all clear", he begins the second half of the examination, in which he probes me with different toys, measuring the depth that they go inside me, and also measuring the elasticity of my hole, as well as testing my strength by making me push out the various toys that go in.
More semen and urine samples are collected from me, with each new toy that is pushed inside of me.
After the doctor deems enough tests have been run, I am given a clean bill of health, and a follow up appointment is scheduled....
