Take the brush first

When you touch the brush, snakes burst from your hair, slithering down your shoulders.
You struggle to comprehend what has just happened. With horror, you realize that your hair has become an extension of their green bodies, an eldrich curse!
It's strange, but the heads of the snakes are like plants... or... wait... like cocks?

A big one twists around your body and pokes your ass, you try to grab it, but it's slippery. Powerless, you try to hold it, but the snake impales your ass as your scream in pain. You feel the cold, plant-like snake invading your inside deeper and deeper... the pain is unbearable.
Alarmed by your screams the nun praying at the end of the room calls for help.

They found you on the floor, with no more strength to fight or even stand up, begging the nuns for help.

They explain "You have awakened the parasite. He will feed from your bowels, we will provide you plenty of food until he flourishes." Your stomach churns, you feel hopeless... you are going to die? they read the fear from your face and say "You can survive, some people did it when the time comes, the tentacle will get out from your ass, and you will expel the seed" You panic, crying, thinking about your miserable life, but they continue. "It's big as a watermelon, but we will prepare our best nurses to save your life, there is a story about a nun who survived the birth, but her legs were paralyzed and she had to wear diapers for the rest of her life... but she was brave and survived! now you can only rest and eat."

You can't endure the information, your vision blurs, you want to puke... and you finally faint.
The next months were terrible, full of pain, discomfort, and horror, as your belly grows more and more, you start to accept that you will not survive this.

One day, when your belly is about to burst, you feel a sharp pain in your ass and belly, after a few minutes, you are surrounded by nurses, the time comes...
The next part is too strong to describe, but when the huge watermelon is out of your ass, you are too weak and you lose too much blood and energy to survive this gore, traumatic experience.

THE END
Watermelon birth ending
