I'm not quite sure how long this will be, but here it goes:
I've always fantasized about being strapped for cash and finding a paid medical study.
Once there, I'm asked a series of humiliating questions. Then, I am required to completely undress. When I ask for a gown, they quickly snap that this study does not permit gowns.
I'm then led from the interview room, naked, to the examination room. I'm then told to lie on the table and my knees are placed into the crutches and strapped down. They soon move to my arms to restrain them and I start to protest out of shock. That leads to them attempting to pry my mouth open with a dental gag, but I refuse to open my mouth, so they pinch my nose and eventually, I have to breathe and that's when they make their move.
I am now restrained, gagged and completely exposed.
Then, a younger male, around 32, walks in and introduces himself as the doctor performing these tests today.
It starts off with a rather painful, but exhilarating breast exam that ends with two clamps being placed on my nipples. He then moves to between my legs and asks me if I'm ready for some painful pleasure. My eyes grow large, but all I can do is nod thanks to the dental gag.
He holds up a speculum so I can see. He mentions that it's been kept in a freezer in order to test my internal reactions to cold stimuli.
He gingerly touches my body before quickly ramming the speculum into me. I can feel my vaginal walls tightening immensely around the cold steel. I release some sounds from behind my gag and I throw my head back all while my vagina is having its own party. The doctor is furiously taking notes and examining all of my reactions. He then produces two ice cubes and hold them on my aching, alert nipples. The ice burns terribly, but I can do nothing to stop that.
Thinking I was close to done, I am quickly informed that we had just begun.
Numerous tests were performed with cold stimuli, warm/hot stimuli and sometimes, a combination of the two. I achieve many orgasms and due to the nature of the study, I have to return every day for a week.
