Follow her out of the room and try to escape

You slowly wake up, you feel the cold floor with your naked feet, the voice lied to you, the place is empty, the nurse enters a room with a sign that says "Lab"
You follow a long corridor with an exit sign, and you arrive at a locked door, a doctor notices your presence, and you try to run, but you listen to a loud sound, a pinch in your butt, and you faint, the last thing that you remember is the hard cold floor on your face.

You wake up on a stretcher, in a white sterile room, with a pillow under your waist, and throw nurses with rubber gloves at your side.
Lying helplessly on the stretcher, the room spins around you. They secure a thick hose with lubricant in your ass. The hose is connected to a huge enema bag. You don't feel pain, but as the liquid begins to flow, you feel a warm sensation on your belly, your insides slowly expanding, a bloating pressure that grows...

You try to move, but the sedatives are too strong, you can just lift your body with your weak arms, and you can't move your legs or any other part of your body, you just feel the warm fluid invading your insides.

"Looks like we have a little wriggler" one nurse says with a smile, watching as you struggle against the ****'s paralyzing effects. Meanwhile, the other nurse checks the flow of the enema, ensuring it's just right. "The enema is huge and prepared for special patients who want to escape, I can assure you that when the whole enema is inside you, you won't be able to walk, but don't worry, we will assist you from now on" and she points a wheelchair in the other side of the room.

You moan in pain, you try to say something, but your tongue is numb, and you just babble...

"Shhh... Just relax and let the medicine do its work." The first nurse says grabbing your butt.

As your belly distends more and more, the pain is unbearable, you think that you are going to explode... no matter how hard you push, not a single drop of enema comes out from your ass.

"You really should have thought twice before trying to escape" the first nurse says. "This is what happens when you don't follow the rules."
She smiles when the first tears come out of your eyes. "Just a bit more darling, I promise that you will survive."

When the enema bag is empty, they secure a huge buttplug inside your ass, when you feel it inside you, they push a button and it starts to inflate, and you think that your ass is going to tear apart.
The nurses help you sit up, you feel a terrible pain and you moan as you adjust to the new, swollen state of your belly. The reflection of your distended belly in a mirror amplifies your humiliation and embarrassment.

"Don't worry, you'll get used to it" one nurse rubs your belly as she helps you into a wheelchair. The other nurse agrees "You will produce more semen and no more escape attempts, it's painful at first, but trust me, after a few days you are going to be fine"

The nurses ignore your moans and distress, they begin to wheel you towards the lab.

Entering the lab, with horror, you notice other men and women, with large bellies, all of them in wheelchairs as you.
"You are not the first one trying to escape darling, you are not special" the nurse says with an evil smile.

The nurses position the wheelchair next to a large, intimidating machine, and connect your penis to a milking device.
They explain that you must get used to the feeling because every 24 hours they will empty your belly and replace it with a new enema.

Despite the terror, there's an odd sense of resignation. This is your life now, and you must learn to endure it. You finish your days sedated, watching the numbers of the extracted semen, how many fluids are inside your body, your temperature, and your heartbeat.

THE END
Bad End: Full belly livestock
