Before I get into my FANTASY, would the safety police please note that this is fantasy and would be extremely dangerous and probably illegal to attempt.
My fantasy involves pharmaceutical restraint. As I'm prepared for some invasive procedures, an IV is started and some of the paralytic agents used in surgery are administered. I loose control of my muscles and my ability to breathe. A breathing tube is placed to keep me alive. I'm wide awake.
There are mirrors so I can watch as things are done, and the entire process is being video taped for later review. My gown is removed. I'm completely naked on the operating table. My body is shaved from neck to toes. My legs are raised and spread to allow shaving of my groin and perineum. Yes, I'm turned face down to shave my back.
Body measurements are taken - detailed, every bit and part are fondled and measured. The staff discusses my body in a very impersonal manner. Electrical stimulus is used to test my muscles and other reactions.
There are multiple procedures scheduled, urodynamics, a rigid cystoscopy, barium enema, full colonoscopy, gastroscopy and more. No anesthesia is used. I feel everything. The staff treats me like a simple hunk of meat.
After they're done, they add something to the IV and I become unconscious.
I wake up naked and uncovered, alone in a hospital room. There's a TV and a remote. As I regain my senses, everything is sore. I reach for the remote and get to watch the show that I'm the star of. I'm amazed by the finale, completed while I'm unconscious.
