As you enter the room, you are surprised, the place is clean, with a well-maintained stretcher, and... wait...
The flickering lights reveal disturbing pictures on the wall, the overstretched pussies of the patients make your stomach churn, they are full of piercings and they look unnaturally big.
Also, you notice huge dildos, plugs, and other creepy instruments to stretch their vaginal cavities. The pictures of the walls are tagged with days, following the process from day 1, with a pierced pussy, to day 20, when it looks like a disgusting meat cavern.
Full of fear, you try to step out of this creepy place... but you smell something strange, like the scent of flowers or candy, before you can think, you fall asleep on the floor.

You wake up on the stretcher, 4 nurses around you, the firm hands of the nurses hold you in place frightened, you try to escape, but your body is extremely weak and heavy, they help you to sit down on the stretcher. You feel a terrible pain between your legs, and when you look down, you immediately panic, and your heart pumps fast, very fast, full of fear. Your breasts are now large, like huge balloons, and your pussy is full of piercings, and on the wall, you can see a picture of your body, your face, and your pussy tagged with "Day 1"... with the strength of the adrenaline, you try to get free, but you faint from the effort and the stress.

You wake up again, and the pain between your legs is unbearable. A nurse is caressing your forehead and asking you to sit down, slowly. You try to speak, but you just drool and babble. Another nurse unplugs your pussy, you moan in pain but feel relief.
One nurse helps you to sit down on the stretcher, while another gently puts some healing cream on your stretched pussy. You notice a huge dildo at your side, covered with your pussy juices... that thing was inside you??
"It’s alright, take this slowly" one says, her voice is nice, treating you like a poor girl in pain.
You start to cry, you can't believe what's happening...
"There’s no need for those little tears, shh." she says caressing your hair "In only 20 days you will have a gorgeous pussy, you will see." The nurse points to the wall, it's already a picture of your pussy on day 2, more stretched.

Day after day, the exercises and the training of your hole are difficult, you can endure the pain thanks to the powerful sedatives, but you don't have any hope to escape... with sadness and resignation, you follow their orders.

There is a forbidden tale that tells about the cruel treatment of the nurses, how the normal pussy of the girl trapped in the upside-down becomes a meat cavern. But this is another story, for another day.

THE END
Meat cavern ending

Task: Cover a table with a towel and insert a huge dildo in your pussy, or a safe insertable object, something challenging and painful, use abundant lube. Put on clothespins on your labia major and wear a filled bra to simulate your huge breasts. Close your eyes and wait 5 minutes. Pretend to wake up, act weak and sedated. Imagine your disgrace, look at your pussy and act frightened. Pretend to faint because of the trauma. Close your eyes and rest for 5 more minutes. Wake up again, acting sedated, caress your forehead, and imagine the nurse. Sit down and drool over yourself. Unplug your pussy, moan with relief and pain. Use a big sock on the dildo, like a condom, and cover it with a real condom, lube it, and insert it again, will be wider and more painful. Slowly move it to stretch your pussy for 5 minutes. Cum during the process looking at the pictures of the meat caverns and think that soon you will be like them. Pretend to faint again... think that it's just the beginning and this will be a nightmare.
