Stay in the tunnel

You stay in the tunnel, observing the movements of a nurse who is patrolling the area, however, the doctor follows your body fluids through the tunnel and he finds you.

You run, but he shoots you with a tranquilizer gun a few times, a shot impacts your butt, and you try to run to the fence, but when you feel the cold metal in your hands, you start to fall asleep.

The doctor carries your body and hides his mistake. He sedates you and starts a complex surgery, to be sure that you will never escape again.
You are in a gynecological chair, and he installs a small device on your womb to release hormones that affect your brain and sexual desire, it also generates terrible pain when you walk outside his office or you try to do something hostile to another person or you try to harm yourself.

After some failed attempts, you are on the floor, begging for mercy because of the pain, and you understand that you have to try to live here.
The sexual desire is difficult to manage, and you masturbate every night, but your fingers are not enough... you don't know anything about the hormones, and you think that it's just a side effect of your captivity.

Slowly, you start to talk to the doctor and cultivate a relationship of mutual respect. He lets you read, watch the TV and even help him with some basic research.
But one day, you can't endure anymore, you take off your clothes and walk to his room, you knock on his door, ready to confess that you need a cock and you are ready to do anything.

You finish your days degraded, doing whatever he wants to have a cock between your legs... you never tried to escape again, because you know that is impossible, and you get used to your new nymphomaniac life.
