Rarity lay in her fancy bed unable to move or scream out loud from the intense itching coming from her cooch. All she could think of was scratching the inside of her marehood, but she could not move a single muscle. It seemed whatever that was ailing her turned off her nervous system. Her pussy was itching like wildfire spreading all over a doomed forest. Rarity continued to lay in her bed, her face cringing from the intensity of it.
She had tried to scream before when she woke up with the sensation, yet she could not make a single sound. She could feel her body itch all over slowly and gradually until it became unbearable. Tears poured down from her eyes as the itching did not stop its campaign. Soon she waited and continued to feel the itch almost posses her that she could barely feel her marehood any longer. It seemed that there was something going on inside, but she could not explain it.
Rarity then heard a voice coming from the stairs up to her room. It sounded like Sweetie Belle's singing, it stirred Rarities hope that she would be saved. The door slowly creaked open to find a smiling Sweetie Belle opening the door to check on her sister. At the sight of her sister so motionless and quiet, she interpreted it as something wrong.
"Rarity? Is everything all right?" said Sweetie Belle. Her eyes agape from worry of her sister.
Sweetie Belle trotted up to her sister's bed to notice that she was crying without making a sound.
"Rarity! Why can't you talk? Whats wrong?"
Rarity positioned her eyes to look down at her pelvis in hopes that Sweetie Belle would scratch the itch.
"Is it something down here? let me uncover the mattress and see..."
Sweetie Belle uncovered the mattress and jumped back from the miasma of black that emanated from the hole. Sweetie Belle closed her eyes, her iris burning and her tear ducts leaking from the disgusting stench. She opened here eyes to see the vagina with two black eyes and what seemed to be lips protruding from the vagina.
"Why hello there young filly! What brings you to these bed chambers!" said the vagina. It's face absolutely happy to see someone other than darkness under those covers. "I am quite thankful for you getting rid of those dreadful covers!"
Sweetie Belle looked upon the talking vagina and screamed as if it was the end of days. Her scream resounded all the way to Sugar Cube Corner and no one took heed of it. Sweetie Belle after her loud and long scream, paused in shock to look at the vagina in horror.
"Oh I am sorry good filly! Did something scare you? Maybe I can fight off whoever the scoundrel is who dared to hurt someone as young as yourself." said the Vagina. The Vagina smiled at Sweetie Belle's shocked expression. "Will you be needing anything young lady to help with whatever scared you? Or will you be just fine?"
"Y-you c-c-can talk?" said Sweetie Belle.
"Why of course I can talk! I have been jib jabbering for a quite a while."
"Wha... What are you!?"
"Well I guess an introduction is in order! My name is Hemotejofan or Hemo for short. I am known as quite a gentlemen in the virus circles! You should meet my good friend Yersinia Pestis or what you ponies like to name him.... The Bubonic Plague?"
"What have you done to my sister!?" screamed Sweetie Belle.
"Oh not to worry! Your dear sister is just fine! She will die, but she will serve a good purpose." said Hemo as cheerily as ever. "We will mold as one and become a new entity of disease and pony! It will be something interesting don't you think?"
"No! I won't let you!"
"Ah, but you don't have much of a choice. If you lay a hoof on me then I will kill your sister, but if you go ask for help then I will kill your sister! Well.. If you do anything either way I will kill her. So there really is no point my dear filly."
"Wha... no... why are you doing this!?"
"Just an idea that me and an old chap thought of! It would be something interesting to do other than infecting ponies all day and killing them! Now don't you think thats something better?"
Sweetie Belle stood there shocked not knowing what to do, all she could do was freeze in fear.
"Oh don't be like that young filly! Here is something to look forward to! the Transformation is about to start!"
Rarities body then began to expand from her stomach, her eyes closed as she breathed her final breath. Her entire face flattened as the disease sucked her insides into a big ball of flesh protruding from the stomach. All that was left was skin, the ball expanded and broke through the epidermis showing a mass of black. Fleshy arms began to protrude out of the floating ball and a head grew out of it's top base. It all looked similarly like a horse, but shaped more-so like Rarity herself.
The fleshy tail sprung up from the hind quarters of the ball and shaped up to become a sort of sharp tail. Her mane was similar to her counterpart, but was different in that it was sharper and dust emanating from the hair. Eyes protruded from the mass of flesh and the whole pony solidified.
The Disgusting Pony pulled its mouth, ripping it apart from the roof and bottom of the snout creating a mouth.
"I am complete!" said The Disgusting Pony.
"Rarity is-s-s that you...?
The Disgusting Pony pulled its tail aggressively, ready to strike the little filly before her. Sweetie Belle was pierced instantaneously and filled with virus gook that would have transformed her like Rarity. Yet, something was not right, it seemed that Sweetie Belle had developed and immunity to the disease and was unaffected. Anti-bodies traveled through the Disgusting Ponie's body and began to convert everything back.
the Disgusting Pony screamed in pain as it felt its disease fused body become cleansed by Sweetie Belle's anti-bodies. Rarity had returned to her form leaving Hemo gone forever from her body. Sweetie Belle seeing her unconscious sister lay on the ground limp hurried to caress her body and sobbed until she awoke. Rarity awoke from her slumber to feel Sweetie Belle's body tighten hers.
"What happened Sweety? I thought I died!" said Rarity as she stirred.
"It doesn't matter... as long as I have you still here! It all doesn't matter! I don't ever want to lose you again!"
"It's alright Sweetie Belle! This time I will stay the hell away from benches! I'll make sure to stay more safe."
Rarity vowed to never sit on a bench ever again and Sweetie Belle soon got Horse A.I.D.S..
The End.
