Discovery and Transformation part 1

"So why are we looking in the old royal library again?" A cyan blue pegasus asked as she looked at a set of books from a high shelf.

"Because the princess's asked us to get an item that was forgotten here and needs to be brought to the palace before anypony else finds it." A lavender unicorn said as she searched through the library.

"And tell me again what the item that we're looking for looks like again, Twilight." The cyan blue pegasus said again.

"Its in a burlap sack and no matter what its not to be opened, got it Rainbow Dash?" Twilight said with clear frustration.

"Yeah I got it." Rainbow Dash said as she noticed a small notch in the wood. "What's this?" Rainbow muttered to herself as she looked at it closer, as she touched it with her hoof and as soon as it was touched the grain parted and revealed a book that was entitled as Daring Do and the Cursed Book. I think I found it, but for some reason I feel like I shouldn't tell Twilight, not yet anyhow. But it seems like it’s calling out to me. As Rainbow Dash was thinking her hoof was absent mindedly moving towards the book, and before she knew what was going on she had the book in her hooves and had opened it reading a few paragraphs. Strange it seems that I can read it but I've never seen this language before.

"Let me see that book."

"What?" Rainbow asked as she was shaken from her thoughts and back to the real world.

"Let me see that book." Twilight said as she used her magic to take the book from Rainbows hooves and looked at the cover.

“Okay now that you’ve looked at it can I get it back now?” Rainbow asked impatiently.

“Fine here.” Twilight said as she gave the book back to Rainbow Dash.

“Thanks! Now can we go home whatever it is we’re looking for obviously isn’t here.”

“Fine we can go. It isn’t here.” Twilight said as she examined another shelf of books.

“Okay. I’ll race you!” Rainbow said as she started to fly out of the old castle. After Rainbow Dash was outside the building started to fall apart. Oh horseapples. Rainbow Dash raced back into the building and found Twilight stuck under a large marble pillar that had fallen on her legs.

“Rainbow Dash help me!” Twilight yelled as another pillar started to fall where her head was. Twilight covered her head and waited
for the pillar to kill her, but it didn’t come, all she heard was a cracking sound and grunts of pain. Slowly opening her eyes she saw Rainbow Dash standing over her with pillars falling on her back, rocks falling down onto rainbows head, and blood dripping from her mouth. “Rainbow Dash, you're-” Before Twilight could finish her sentence Rainbow leaned down and grabbed her by the back of her neck and dragged her out. After a few minutes Rainbow Dash was only a few feet away from getting out of the building, when three more pillars started to block their escape route. Calling up her strength she threw Twilight outside as the building crumbled on top of her. “Rainbow Dash!” Twilight yelled as she noticed that her friend was still under all the rubble of the building. Twilight tried to get up to find her friend but her legs were broken. Twilight then decided to try and drag herself over to the rubble. When Twilight started to drag herself the rubble started to shake and move as Rainbow Dash stood up from the rubble unscaythed.

“Aw man that shit hurt, but lets get you to the hospital.” Rainbow Dash bent over and grabbed Twilight and took her to the hospital.

“Wait what about you? Your back is broke and you're badly hurt.” Twilight asked as she noticed Rainbow limping slightly.

“I’m fine you need medical help more than me so shut up and let me get you to the hospital!” After a few hours of bickering the two ponies arrived at the hospital.

“What happened to her?” The pony at the front desk asked as she saw Twilight come in gravely injured.

“We were doing something for the princess and the building we were in collapsed.” Rainbow Dash explained everything from when she had rescued Twilight.

“Okay get her to the E.R. and we need to look at you as well.” A nurse spoke as Twilight was taken to the back.

“No you don’t. I’m fine just a little sore thats all.” Rainbow said.

“Im sorry Ms. Dash, but please let us just do an X-ray to be on the safe side.” The nurse pleaded.

“Fine, but I guarantee you that I’m fine.” Rainbow said with a sigh of irritation.

“Okay, thank you for letting us do our job.” The nurse said as she scanned Rainbows body.

“Rainbow Dash you have five broken ribs, your back was broken in fifteen different places, some internal bleeding and hemorrhaging. We’re gonna keep you here until your body is completely healed. We will give you the same room you always stay in.” The nurse spoke with a certain awe struck tone.

“Uh! No you won’t because I’m not hurt and to keep me here you’ll need to strap me down in the bed before I stay here when I’m not hurt.” Rainbow said as she crossed her fore hooves.

“Rainbow Dash look at these X-rays of your body you can clearly see all the brakes and everything so stop being a little foal and stay here until you are fully healed. we will even give you magic healing to speed it up alright?” The nurse was starting to get irritated.

“No I’m not hurt in any way so I’m not staying, you bitch ass whore.” Rainbow said as she turned to walk out the room.

The nurse looked in shock “I am not a bitch ass whore my name is Redheart and you better call me as such do you understand me?" Redheart said shocked by what one of her patients had just called her.

“Yeah whatever bitch ass whore.” I could skin you right here and now if I wanted to. Wait where did that come from? Probably doesn’t mean anything.

“I don’t care what you say Ms. Dash you're staying here until you're better and to help me on this I sent word to your friends to come in.” Redheart stated as Fluttershy, Applejack, Rarity, and Pinkie Pie came into the room.

“Why? I’m not hurt at all!” Rainbow tried to make a run for it, but Applejack grabbed her with her trusty rope and threw her onto the bed hog tieing her

"Now sugarcube we're only doing this for your own good. I promise you that you will be out of here in no time." Applejack said as Rainbow looked at her with eyes full of boiling rage and hate.

Watch me eat that flesh off your redneck ass right after I'm done plowing it into the ground with my huge throbbing shaft bitch. Wait where the hell did that come from?

“Fine I’ll stay but only for today.” Rainbow said as she rolled her eyes.
Rarity shook her head.

"No Rainbow dear you need to stay here for at least a week.”

“Fine but when I say I’m leaving I mean it.” Rainbow stated without much room for argument.

“You're as stubborn as a mule.” Applejack joked.

Pinkie nodded "I should know!"

After three days Rainbow had decided she had enough and got out of bed to leave. “Where are you going Ms. Dash?” Her personal nurse asked.

“I’m leaving, and there’s nothing you can do to stop me.” Rainbow said as she turned to move out the door when she was tackled to the ground a was being strapped back to the bed.

Twilight walked into the room "Rainbow this is for your own good. If you would have taken the magic medicine like I did you could've been out by tomorrow morning"

“Like hell I’m gonna stay here without a reason to stay.” Rainbow yelled as the hospital staff tried to strap her to the bed. After a brief struggle Rainbow was able to move her left hoof and was swinging it around and knocking the staff members away one by one. Before Rainbow could get up after all the staff was off of her, a big strong stallion jumped on her to hold her still. Getting her fore hooves free she grabbed the stallion by the back of the neck and sunk her teeth into his neck piercing the skin and digging into the muscle. The stallion let out a scream of pain as Rainbow pulled back pulling the muscle with her mouth until it ripped off, leaving a big hole in the stallion’s neck bleeding freely, before kicking him over to the door. Seeing this Twilight ran out the door and tried to close it but the stallion's head fell between the door and the wall lifeless. Twilight was able to get the stallion’s head out of the way and closed the door before locking it. She looked through the keyhole and saw Rainbow Dash walking up to her personal nurse who was cowering in the corner of the room.

“P-p-please d-d-don’t hurt m-m-m-m-me.” The nurse stuttered.

“Oh don’t worry this will only hurt a lot for you but I won’t feel a thing. Now name how you die at the hooves of one of your patients.” Rainbow said as she got face to face with the nurse and snickered.

“I-I-I d-don’t want t-t-to d-d-die.” The nurse stuttered as Rainbow got up closer and pinned her to the floor and pressed her body on top of hers. As the nurse cowered she felt something touch her between her legs.

“Well to bad because you should have just let me go when I said so.” At that moment a big red pony with bat wings and four horns came in through the window and was absorbed into Rainbow Dash.When the strange entity was absorbed into Rainbow she fell over and started to yell in pain. Her hooves moved to her head as the voice got stronger and stronger. She flew out the window and into the sky. As she flew her body started to change rapidly. Her wings morphed into demon like wings and her forehead started to grow four small horns. Her fur slowly changing into a blood red color and razor sharp teeth grew in pushing out her old ones out. As she morphed she was also losing altitude and was gonna crash. The last thing Rainbow knew was that she hit the ground with enough force to break a new castle.

The worrisome dream

Rainbow woke with a start, completely drench in sweat and panting heavily. Taking a look around the dark room slowly letting her eyes adjust to the dark, she noticed that she was in the hospital. Her head pulsated with a migraine as Rainbow sat up in the bed.

"Fuck. My head." Rainbow grunted as she tried to clear her mind. Getting out of bed she trotted to the bathroom to splash her face. After she dried her face she looked in the mirror. What she saw made her gasp and stumble back.

A pony that looked like her, but clearly wasn't was staring at her with an evil smile that revealed sharp filed teeth, the mane and coat of this pony was much darker, her eyes were solid black except for a red pupil. The mare placed her hooves on the mirror and started to push through the glass as it rippled like water. The mare kept pushing through the mirror, now half of her body was through the mirror and she had her eyes locked on Rainbow as she cowered in the corner.

Rainbow tried to move, but she couldn't. She couldn't feel her hooves, and looking down at her hooves made her even more terrified.

She could see right through her own hooves. The sound of glass breaking drew her back to the mare from the mirror. She was now standing in front of her. Looking at her with those blood red pupils. Smiling at her with those filed teeth. The mare's large cock barely touching the ground.

Rainbow's eyes widened when the cock twitched. Rainbow tried to scream as the bathroom door was smashed in, but no sound came out.

A big red stallion with bat wings and four horns stepped through the door staring at Rainbow before passionately kissing the mare from the mirror. Rainbow Dash screamed as she fading away.

"AHHH!" Rainbow screamed as she jerked up right in her bed. Her head was aching, almost like somepony was hammering her head. "Oww." Rainbow rubbed her temples trying to ease the pain.

"Your head hurts? Well I wonder why?" a voice said as Rainbow heard the sounds of hooves coming her way. "Maybe I should help you feel better." a door swung open and a pony stepped forward. The sudden bright light caused her to squeeze her eyes shut and reel a bit. As the light died down Rainbow saw the mare from her nightmare. She was wearing a bloodstained nurse's outfit.

"No, it can't be. You're not real. I must be dreaming." Rainbow said as she felt thick leather straps wrap around her barrel and pull her to the bed.

"No, you're not dreaming. You're really bout to be replaced with me." the mare said as she smacked Rainbow with enough force to knock a tooth out. "You're time is up." the mare struck Rainbow in the stomach causing her to groan in pain. "But don't worry, I'll take care of your body." the mare said seductively as she started to rub Rainbows pussy causing her to moan in pleasure.

"W-why?" Rainbow stuttered as the mare massaged her clit. Rainbow couldn't see the mare lower her head to the pussy of the athletic cyan blue pegasus.

"Why what?" the mare said as she ran her tongue along the wet lips between Rainbows toned legs ellicting moans from her as the mare latched onto her clit and sucked hard.

"Aahh!" Rainbow screamed arching her back, fighting against her orgasm.

"About to cum already, not good. I'm not even close to cumming." the mare said seductively. "Oh well. I'll just have to teach you a lesson in respect." she said licking and sucking on Rainbow's pussy.

"Aahh!!" Rainbow moaned loudly as she started cumming.

WTF is happening to me?!

Rainbow woke up as she was squirming and squirting on her bed. "Oh no." Rainbow moaned her face cherry red. As she went to get up she felt something touch her barrel and press against her legs. Looking down she saw the monster of a dick she was packing. Unsure of wether it was the dream or something else, Rainbow couldn't help but careen her neck and lightly lick the head.

The little action caused her to moan as she swirled her tongue around the head of it.

What the fuck am I doing?! I know that I'm sucking on a dick that I have never had, but it just feels natural, right, I want to taste... Rainbows thoughts were cut short as she tasted the salty taste of pre. It was intoxicating, it sent her mind into a daze, all she could think about was getting a taste of the cum. Without taking the dick out of her mouth, Rainbow rolled over and raised her flank as she pushed more of the dick in her mouth.

As her pussy clenched and squirted, Rainbow sucked on her new dick and slowly stroked her dick.

It wasn't long before she felt a burning sensation in her groin. It felt odd but familiar at the same time. It wasn't until she felt cum shooting into the back of her throat did she realize what the burning was.

Mmm. So warm, and creamy, I love it. If I had known that a stallion could produce something like this, I would have taken Rarity up on that offer. I wonder if Big Mac tastes like this. Rainbow moaned as she felt her stomach start to buldge a bit causing her to pull it out and let her face and chest get coated with cum. For the next few minutes, Rainbow was laying there as she covered her body in her own cum. "That was. So awesome."

Rainbow sighed contently as she slowly drifted off to sleep, before a knock on the door snapped her awake again.

"Rainbow, darling? Are you in there?" Rainbow instantly recognized the voice as Rarity's. Perfect. She's such a slut, maybe I can make her take this inside her slutty body.

My slutty Rarity

"Yeah just give me a minute!" Rainbow said getting up and cleaning up a bit before answering the door. "Hey Rarity. Come in." Rainbow stepped aside and allowed the shapely white unicorn to come in. I can't wait to plow that fat ass and sweet little pussy.

"Darling, is there a horny stallion in here?" Rarity asked scrunching her nose as the overpowering sent of stallion hit her.

"You can say that." Rainbow said as she licked her lips. "Hey Rarity?"

"Yes darling? What is it?" Rarity asked not turning around.

"I'm ready to take you up on your offer. The one about you teaching me how to please a stallion."

"Oh that's great news, darling! I thought you would never ask!" Rarity exclaimed as she hugged the prismatic mare.

Rainbow smiled lustfully and pushed her to the floor.

"Let's get started then." Rainbow said as Rarity finally sees the source of the smell.

"Dear Celestia! What in Tartarus is that!" Rarity exclaimed her eyes widening.

"It's the dick you'll be sucking and fucking. Now get to work my slutty Rarity." Rainbow said as she moved to Rarity's mouth.

Rarity inhaled the musk from the dick that rested upon her face. It drove her crazy with lust. She stuck her tounge out and lapped at the balls working her way up to the glistening tip. The taste of her friends pre was what drove her to act completely on her primal desires and suck on the thick dick. Sliding in down her throat and deepthroating it in one go. Rainbow and Rarity moaned as Rarity started to bob her head in an instant rhythm.

"You really are a slut Rarity. Knowing how to expertly deepthroat my dick without gagging." Rainbow moaned softly and bucked her hips harshly.

Rarity didn't hear a word as she kept sucking harder. Or so Rainbow thought. Rarity removed the dick with a wet pop and started stroking it and licking it.

"Yes I'm such a slut. Let me be your slut. Fuck me. Please." Rarity begged with lidded eyes. "Please Daddy." Rainbow put a hoof behind her head and shoved her dick back into Raritys throat before bucking her hips harshly.

"Suck my fucking dick you slut." Rainbow said as she shoved Raritys head to her base and started cumming.

Author's Note

I know Raritys actions are not very believeable, but I'm sticking with it. Once it gets published, it isn't getting changed. You can't do that with real world stories, ones that are in books. So I'm going to do it like that.

Prolouge

"Why are we hiding this again big sis." Luna asked a Celestia as she put a burlap sack in a secret area in the library at the Royal Palace.

"Because this puts a curse on anypony who opens it, and it can't be destroyed, so we're hiding it in the library so no more of our subjects are killed by it, okay Luna?" Celestia said as she put the item into a little vault at the back of the library.

"Who even made that thing?" Luna asked as the two alicorns trotted away.

"Nopony knows. It was found three years ago by our father. When he found it and took it from an old temple he started to have crazy dreams and bad thoughts. After the first week he was able to fight the curse by holding on to what was dear to him. But after that week the curse overthrew him and his friends started to disappear without a trace. After a month the local police found him with one of his friends following him into an alley, so they started to follow them to an old abandoned meat factory, where everypony that went missing was found dead. So the police had to kill him before he killed anypony else."

"So that's why we're hiding it the royal library's book vault?" Luna was starting to get confused again.

"Yes Luna that's why we're hiding the book, so that Nopony can ever get hurt again." Celestia said with a sigh of irritation.

"Okay, one more question, why don't we just throw it in the Everfree Forest?"

"Because I don't want Zecora finding it and getting cursed by it."

"Okay."

"Then lets just hope that nopony finds the vault."

"Agreed."

Transformation part 2

Rainbow spasmed there in the grass, tossing and turning as she clutched her head screaming in agony. "What's happening to me?!" Rainbow screamed arching her back.

Just relax and enjoy the ride, Rainbow Dash.

"What? Who-who are you and what do you want from me?!" Rainbow asked the voice she just heard.

I'm the entity that you released from his prison when you read from the book. As for what I want, I want to curse the entire world. As we speak I'm taking over your body, mind, and soul while, at the same time, making changes to your thoughts and anatomy. I'm pretty sure you have noticed the thoughts. Soon I'll be in complete control of your body, and when that happens, I'll take over this pathetic world.

"Why did you wait until now to do this?" Rainbow spasmmed arching her back and gritting through her teeth.

I had to wait until you made your first kill and tasted the blood of the victim. When you killed that stallion you allowed me to enter. Now with the help of your athletic build I can finally get my revenge. Now just relax and enjoy the rest of what is you while you still can.

As the voice laughed manaicaly Rainbows body made its final changes. Her eyes changed to the darkest black with a red pupil in each eye, her muscles became even more defined and bigger, her coat became a darker blue as her mane and tail faded in color brightness, and a set of balls and a 20 inch member grew.

"N-no! I-I-I won't let y-you get away with this! I-I-I will fight back!"

It's too late for that Rainbow. You're now under my curse. You'll no longer be known as Rainbow Dash, you're now Dark Rainbow.
