knock out the old man

You approach stealthy, and you land a powerful hit with the iron bar on the head of the old man, he falls on the floor, and the nurse quickly shoots you with a tranquilizer gun.

You listen to the explosion, and you notice the dart in your chest. After that, you fall asleep.

You wake up immobilized in a gynecological chair. You are gagged, and you feel something between your legs, discomfort in your ass, in your belly, and also a constant urge to pee and to poo... fresh air inside your vagina. What's happening?

You notice the nurse taking some samples inside your vagina, you can't believe that you are watching. There is a huge enema bag connected to your ass, and another connecter to your urethra, and a big speculum keeps your pussy open... you feel your belly and bladder full of warm water.

Your pulse rises uncontrollably, and the beeping sound in the machines sounds an alarm. You begin to hyperventilate... but the nurse applies some medicine inside your pussy and you immediately relax. The alarm stops, and you breathe softly through your nose.

The nurse explains that the doctor is dead, but she has some personal ambitions, learning more about the female orgasm related to the capacity of the colon and the bladder. With some **** and touching the right spots she will make you orgasm when you are dying to go to the toilet.
You are too weak and dizzy to resist, but you experience a terrible fear and horror in this chair.

Exposed and helpless, you are just a test subject for the nurse, he increases the flow of the enema bag, and you are filled with water, as she said, you are dying to go to the toilet, you never felt that before... moaning is pain and discomfort, you try to beg her, but your beggings are muffled by the gag.

The nurse touches certain points inside your vagina with a steel wand, you think that you are going to make a mess, and you are ****, suddenly, without warning the magic happens! your clitoris starts to palpitate, and despite the horror, the humiliation, and the uncomfortable full sensation on your belly and bladder, you cum like never before.

She uses some big cotton swabs to take samples and kisses you on the forehead, she connects a huge empty bag to your urethra and another one to your ass, and you empty your bowels and bladder inside them.
The nurse explains that you must rest, tomorrow she wants to test with a higher volume. With practice, she wants you to hold 1000ml in your bladder and 6000ml in your colon before the orgasm.

**** and horrified, you can't sleep thinking about this.
Unfortunately, you never return to your world, and you finish your days as a test subject with the nurse.
