Refuse the treatment

You gently refuse the treatment and ask the nurse for any other options.
The nurse puts the syringe on the table and explains that she can arrange something, it can be a challenge for you, but it can be a bit painful.

The nurse leads the way, two silent guards escort you. A metal door opens, revealing an elevator. You descend into the depths fo the hospital.
You are now in a corridor lined with examination rooms, each revealing a different horror.

You start to walk, in the first room, poor girls are chained to the walls, their eyes are hollow, without hope, and their bodies are marked. You listen to their whispers asking for help and muffled sobs... This is a nightmare!

The nurse detects your fear, she places a gentle hand on your shoulder. "You’re a collaborative one, as long as you behave, you’ll be treated well here"
You nod your head, and you continue to watch the horrors inside the different rooms.

In the next room, a girl with pigtails squirms on a gynecological chair, her wrists and ankles are cuffed. You can't believe the size of her belly, is she pregnant? A nurse stands beside her, controlling a large nozzle connected to an enema bag filled with a soapy solution. The girl is **** observing the growing distension of her belly.

And the other rooms are worse, but you don't want to look and know the details, the huge speculums, the brutal tortures, the tools used on their bodies... it's too intense... You just look at the floor thinking about how to escape.
You arrive at a secret entrance, the training room. Obedient girls are waiting, dressed in leather, they have their nipples pierced and you notice that one of them is fighting against a terrible gag reflex... what do they have in their mouths? this is insane!!

The nurse guides you upstairs, to a place that looks like a gym. She gives you new sports clothes and a large anal toy.
She explains that you and the other new girls will start the training, and later you can decide what to do, they will treat you like a guest, but you have to collaborate and follow their orders.
Humiliated, you put some lube and insert the anal toy in your ass, it takes a while because it's big and it hurts. The tight sport clothes have a big hole, exposing your intimate parts.
You and the two other girls are instructed to begin with sit-ups, it's hard because of the pressure and pain inside your ass.
Next, jumps, you are sweated, but you have to survive and find a way to escape.
Finally, you’re told to make squats, the pain in your legs is nothing compared to the anal stretching, you have to clench your ass and endure, the silent threat of the punishments keeps you moving.

The nurse orders you to squat, one by one, she takes off the toy from your insides. She takes a look and says that you need a deep cleaning. She connects a machine and orders you to don't move.

The cleaning brush works deep inside your ass, it's soft but big and painful. You don't dare to move and the other girls also obey.

The nurse is happy with your performance, and she escorts you to another room.
She explains that you are amazing, and you can decide what to do. After that, you will be free to go, and this will be over.

The first option is to keep your virginity and test a new artificial insemination procedure.
The second option is to make some modifications to your pussy, but unfortunately, you will lose your virginity during the invasive process.

Both options are bad, but you have to choose something and gain some time.
