Better to live as a hermit

Nope! I'm not doing this! you think to yourself, and you proceed to go inside the forest. To live a life of complete freedom as they say.

For the first few days, things go relatively well. You make a couple traps, catch some animals, eat some fruits, sleep by the campfire. Then at the start of the second week you start vomiting blue. You experience intense stomach pain, with a severance that increases by the hour. Afraid, you go to the town's square to get some help. Then you start vomiting again, and you collapse on the ground soon after.

"We will have to inject her with the brain altering nanites. That is our only option," you hear the doctor say as you are brought to the infirmary room, all strapped down, biting on a cock gag that was impromptu placed in your mouth.

He is lying. You are sure of it. He only wants to alter your brain to exploit you. Alas: there is nothing you can do, as you are held down by two other men, your body injected with the damned serum.

In the end, what you predicted becomes true. The doctor decides to keep you as his ****, your body serving as a compensation for the nanites. At night, you are with him, pleasing his every desire. At daytime, you are at the fuck-all-you-like, countless guests lined up against your bound form. A small mercy perhaps, that you do this willingly. Once the nanites finished with your brain, sex truly became the cornerstone of your existence. And the rougher it is the better!

BAD END: DOCTOR'S ORDERS
