Part 1

Twilight Sparkle was working hard in her lab on her latest invention. Before her stood a large, metallic ring. It was 10’ tall and 10’ wide. Twilight was putting the finishing touches on the control panel when her dog Spike walked in. His eyes went wide as soon as he saw Twilight’s newest creation.

“Um, Twilight? What is that?” Spike asked.

Twilight looked over at Spike and removed her goggles. She then put back on her glasses.

“This is my latest creation, Spike. I call it The Portal 2.0”

Spike raised an eyebrow. “This is what you’ve been doing with your time instead of taking me to the dog park?”

Twilight scratched the back of her head as she made an uneasy smile. “Yeah, sorry about that.”

“What do you need another portal for? Isn’t there already one in the statue in front of the high school?”

“Yeah, but that portal only leads to Equestria. And so does the one on the island that I told you about. My Portal 2.0 will allow me to travel to realms beyond Equestria. Who knows? I might even make first contact with another species!”

“Twilight, I have a really bad feeling about this.” Spike said with a whimper.

Twilight knelt down in front of Spike and rubbed his head.

“Spike, I’ll be fine! Besides, I've been through some weird things before. Remember when I became Midnight Sparkle?”

“That’s what I’m worried about, Twilight. What if something like that happens again?”

“It won’t. And besides, I was helped by my friends last time. They will surely do the same thing again if something bad happens.”

“I hope you’re right.” Spike said with a sigh.

Twilight stood up and walked over to her computer. After typing in some calculations, she then walked over to the control panel for The Portal 2.0 and turned it on. The device powered on, giving off a loud hum. A bright, white light then appeared in the center of The Portal 2.0 and expanded to encompass the interior of the ring.

Twilight stood in front of it. “Spike! It's working! This is incredible!”

Spike whimpered and backed away. He had a bad feeling.

The white light then turned to a shade of purple. Twilight could not stop looking at it. She felt strongly drawn to it. Twilight then walked up to the purple light and touched it. A second later, she was sucked into it.

“Twilight!” Spike cried out.

A few seconds later, Twilight reemerged from The Portal 2.0. Her hair was no longer tied up in a bun. It flowed freely down her back. Twilight also didn’t have her glasses on, and her eyes were shut. When she opened them, they were glazed over with the same purple color as the portal.

“Twilight, are you alright?” Spike asked.

“Twilight…isn’t…here.” She responded with a wicked smile. She then rubbed herself all over. “Mmm, it feels so good to have a physical body!”

Spike shook with fear. “Who are you?! What have you done with Twilight?!”

“You’re Twilight is no more. I control this body now.”

Spike let out a growl.

“Bad dog.” The girl that used to be Twilight reached out her hand. A purple tendril emerged from her palm and swiped at Spike. Spike dodge out of the way as the tendril cut a nearby table in half. Spike then ran as fast as he could out of the lab and out of the house.

“I need to find help!” Spike thought to himself.

The next day at school everyone was in the hallway chatting and getting ready for class when Twilight burst in. Everyone was immediately taken aback by her new, sexy look. Twilight wore a purple jacket with a matching mini skirt. She also wore a black tank top that showed her belly and knee high purple boots with jagged black stripes. Twilight also wore a pair of purple tinted sunglasses.

Rarity and Sunset approached her. “Woah, Twilight! I’m impressed with the new look!” Rarity said.

Twilight flipped her hair and grinned. “Thank you. I just felt like doing something different.”

Twilight was then approached by Timber Spruce. “Twilight, you are looking good!”

“I’m glad that you like it.” Twilight then leaned in close and whispered in Timber’s ear as she traced her finger across his chest. “How about I give you a more personal look in private?”

“But Twilight, class is about to start.”

“Be a little adventurous. Besides, nobody has to know.”

The bell then rang and everyone headed for class. “Alright. But just for a few minutes, alright?”

Twilight kissed Timber. “You won’t regret it.”

Twilight then dragged Timber into the janitor’s closet and shut the door. “Are you ready for your personal look?”

“You bet!” Timber replied with a big smile.

Twilight then removed her sunglasses to reveal her purple tinted eyes. Timber was instantly freaked out.

“Twilight! What the Hell is going on?!”

“You will feed the darkness.” The purple tendril then re-emerged from Twilight’s hand and stuck its way into Timber. His body began to quiver as it turned into a purple goo.

“What’s happening to me?!”

Twilight placed her finger on Timber’s lips. “Shh, just relax.”

Once Timber had fully turned into purple goo, Twilight sucked him up through her tendril. All that remained were Timber’s clothes in a pile on the floor.

Twilight put her sunglasses back on and rubbed her belly. She then let out a light burp. “Ahh, Timber juice.”

At lunch Twilight sat down with the others. “Hey Twilight, where’s Timber Spruce?” Rainbow Dash asked. “Nobody has seen him since this morning.”

“He had an emergency at Camp Everfree that he had to attend to.” Twilight replied.

The girls didn’t know what to think. A feeling of unease flowed through all of them. As they ate their lunches, they noticed that Twilight wasn’t eating anything.

“Aren’t you hungry, darling?” Rarity asked.

“I already had a big meal.” Twilight replied with a creepy smile.

This caused the girls to feel even more worried.

Part 2

Later that day Rainbow Dash finished up soccer practice with the rest of the team. She helped to put away the equipment, so that made her the last one in the locker room. Rainbow Dash was taking a shower when she heard a noise behind her.

“Hello? Who’s there?” She asked as she turned around. Rainbow Dash was surprised to see Twilight. “Twilight? What are you doing here?”

Twilight walked gingerly towards Rainbow Dash. “I was just walking around, and I noticed that you’re the only one left in the locker room.”

Rainbow Dash turned off the water from the shower. “Yeah, so?”

“I was hoping that we could have some private time.” Twilight now stood face to face with Rainbow Dash.

“Twilight, I know what you’re thinking and I’m not interested. I’m dating Fluttershy.”

Twilight placed her hand against the tile wall. “She doesn’t have to know. Now, look into my eyes.” Twilight then removed her sunglasses and showed Rainbow Dash her glazed over purple eyes.

“Holy Shit!” Rainbow Dash yelled. “What happened to your eyes?!”

“They have seen eternity, and true power. Now look closer.”

Rainbow Dash tried to look away, but she couldn’t. Twilight’s gaze had her trapped. She tried to move, but it was like Twilight had her whole body tied up.

“Now, get ready for some fun.” Twilight then kissed Rainbow Dash on the lips. Rainbow Dash could feel a slight tinge of excitement as soon as her lips touched Twilight’s.

Twilight moved down and put her hands on Rainbow Dash’s breasts. Twilight then proceeded to massage them tenderly. Rainbow Dash let out a soft moan of pleasure. Twilight pushed her breasts together and sucked on the two of them at the same time. Rainbow Dash’s breathing intensified.

Twilight then got on her knees and leaned in towards Rainbow Dash’s exposed pussy. She licked it, which sent shivers up Rainbow Dash’s spine. Twilight also stuck her tongue into her pussy and wiggled it around.

“Hmm, don’t stop.” Rainbow Dash said quietly.

Twilight tickled Rainbow Dash’s clit with the tip of her nose, while also using her tongue to press down on Rainbow Dash’s G spot. The two combined sensations were too much for Rainbow Dash to contain, and she climaxed hard.

“Fuck! Fuck! Fuck yes!!!” Rainbow Dash shouted.

Twilight stood up and looked at Rainbow Dash with a wicked smile. “I can see that you enjoyed that. Then you’re going to enjoy this as well.” Twilight then opened the palm of her hand and the purple tendril came out. It then entered Rainbow Dash’s belly button and began filling her with a strange liquid.

“What are you doing?!” Rainbow Dash shouted with panic in her voice.

“I’m helping you to embrace the darkness.”

Rainbow Dash could feel the liquid filling up inside of her body. It felt weird, like it was erasing her insides and replacing them with something new. The liquid soon made its way up to her head. A purple tint covered her eyes, showing her things she had never seen before. Things from beyond.

Rainbow Dash’s brain then began to change. Mentally, she felt like she was being painted into a corner. Everything that she knew and everything that made her Rainbow Dash was being erased. Rainbow Dash had nowhere else to go. She closed her eyes and cried as the end approached.

Twilight withdrew the tendril when the process was complete. “How do you feel?”

Rainbow Dash opened her eyes. They were the same as Twilight’s, covered in a purple shade. “I feel so good!” She said as she felt up her body.

Twilight nodded. “Welcome to the darkness, sister.”

Part 3

When school let out Fluttershy walked out and looked around for Rainbow Dash. The two of them usually walked each other home. Fluttershy then heard someone calling out her name.

“Fluttershy! Over here!”

Fluttershy looked around and saw Spike hiding in the bushes. She walked over and knelt down beside him.

“Spike, what’s going on? Why aren’t you with Twilight?”

Spike was shivering with fear. “Something happened in Twilight’s lab last night. She was trying to create a portal that would lead to different dimensions besides Equestria. She succeeded, but when she went through the portal she came back different.”

“Different how?”

“It wasn’t her! It was like something else had taken over her body. Something evil! Have you seen her acting strange today?”

Fluttershy thought for a second. “Well, Twilight was wearing clothing that was a lot more sexual than she usually wears. She also acted kind of funny, more seductive. And she had on a pair of sunglasses all day.”

“That must be to disguise her eyes. They’re glazed over with a weird, purple tint.”

“If what you’re saying is true Spike, then what are we going to do?”

“We have to gather the others. Who knows what this evil Twilight has planned.”

Fluttershy picked up Spike and put him in her backpack. Before she walked away, Fluttershy tried calling Rainbow Dash. A worried look then came over her face.

“What’s wrong?”

“Rainbow Dash isn’t answering. She always answers her phone. I’ll send her a text telling her to meet up with me and the others at my house.”

Later, Twilight and Rainbow Dash arrived back at Twilight’s home. Shining Armor was waiting for her.

“Twilight, why are you so late? And why is Rainbow Dash with you?”

Twilight waved her hand at Shining. “Calm down, Shining. Rainbow Dash and I were just having some girl time.”

Shining looked at Twilight and Rainbow Dash suspiciously. “Why are the two of you wearing sunglasses?”

“It’s the latest fashion trend.” Rainbow Dash replied.

Cadence then came in from the other room. “Twilight, there’s a weird humming noise coming from your lab.”

“It’s nothing dangerous. Just my latest experiment.”

“Still, I want you to be careful.” Cadence had a look of worry on her face.

“There is nothing to worry about. Everything will be complete by the time mom and dad come home from vacation.”

Rainbow Dash then walked over to Cadence. “Why do you seem tense?”

Cadence let out a deep sigh. “I just have so much work going on right now at Crystal Prep. Principal Cinch is running me ragged.”

Rainbow Dash looked over at Twilight. They both smiled and nodded at each other.

“You know Cadence, I know a massage technique that will change you forever.” Rainbow Dash said.

“Well, alright. I’ll give it a shot.”

Rainbow Dash then began massaging Cadence’s shoulders.

“How do you feel?” Rainbow Dash asked.

“Mmm, I feel good.”

“And you’re about to feel even better.” Rainbow Dash then opened the palm of her hand and a purple tendril came out. She then placed her hand over Cadence’s mouth, and the tendril began to pump purple fluid down her throat.

“What the fuck are you doing?!” Shining yelled. He tried to rush over to Cadence, but Twilight stopped him by grabbing his arms. Shining tried to fight free, but Twilight was just too strong.

Cadence shook violently as Rainbow Dash filled her up with the purple fluid. Her eyes rolled up into the back of her head, and eventually they glazed over with the purple tint.

Once the takeover was complete, Rainbow Dash released Cadence from her grip. “So, what do you think?” Rainbow Dash asked.

Cadence looked over her body and made a sinister smile. “I love it! This body will do perfectly.” Cadence then looked over at Shining. “And it’s time to give it some energy.”

Cadence then walked up to Shining. “Cadence, what are you doing?!”

“Shh, your body will fuel the power that will rule this world.” Cadence then opened up her hand to reveal a purple tendril of her own. It moved like a snake across Shining’s face and down his throat. His skin then turned purple, and his body deflated like a balloon.

“GAAAAHHHHH!!!!!” Shining garbled loudly as he was devoured. Just like with Timber Spruce, there was nothing left but a pile of his clothes on the floor.

Twilight looked at her sisters and smiled. “Soon our family will be complete.”

Part 4

Rarity, AppleJack, Pinkie Pie, and Sunset all met up at Fluttershy’s house. Once they were all together, Spike told them everything that had happened.

“So, Twilight has become Midnight Sparkle again?” AppleJack asked.

Sunset shook her head. “No, this sounds different. From what Spike has told us this isn’t even Twilight. It appears to be something that has possessed her body.”

“And I still can’t get into contact with Rainbow Dash.” Fluttershy said. “I even called her parents, and they told me that she hasn’t come home. I think the two are connected.”

“Ugh! Ever since magic entered our lives nothing but weird stuff has happened.” Rarity said.

Suddenly, the doorbell rang. Fluttershy got up and opened the door. Gloriosa Daisy was waiting on the other side.

“Gloriosa? What are you doing here?” Fluttershy asked.

“I’m looking for Timber Spruce. He never came back to the camp after school let out.”

The other girls came to the door with concerned looks on their faces. “Twilight told us that he was going to the camp.” AppleJack said.

Gloriosa shook her head. “Something isn’t right. Why would Twilight lie?”

Fluttershy then told Glorisoa everything that Spike had told her.

“We need to go over and confront Twilight. Or whatever this thing is.” Sunset said.

The girls then went over to Twilight’s house. Fluttershy rang the doorbell and Twilight answered. As soon as Spike saw her, he growled.

“Oh hey guys! I see you found Spike.”

Fluttershy held Spike back as Sunset and Gloriosa and Sunset stepped forward.

“Twilight, we need to have a word with you.” Sunset said. “You’ve been acting kind of weird today.”

“Well then, come inside and let’s talk.” Twilight stepped aside and let the girls in. They instantly saw Rainbow Dash and Cadence standing side by side. They were both wearing sunglasses.

Fluttershy rushed up to Rainbow Dash. “Rainbow Dash, where have you been? Why didn’t you answer your phone?”

“Let’s just say that Twilight and I were having some fun.” Rainbow Dash said with a wicked smile.

Rarity looked around. “Twilight, where is Shining Armor?”

“I ate him.” Cadence said with a giggle. Cadence, Twilight, and Rainbow Dash all removed their sunglasses to expose their purple eyes.

“Much like how I ate Timber Spruce. He tasted like candy.” Twilight said.

“I told you this wasn’t Twilight!” Spike yelled.

Twilight then walked around the room with her hands on her hips. “You really should listen to that dog. The Twilight Sparkle, Rainbow Dash, and Cadence you know are no more. Their bodies belong to us now. Soon The darkness will consume this world, and all of you will be a part of it.”

“So join us, or die.” Cadence said.

“There is no way we’re letting some monsters like you take over this world!” AppleJack shouted.

“You’ve made your choice then.” Rainbow Dash then released a purple tendril from her hand. She aimed it at AppleJack and cracked it like a whip. A second later, there was a spray of blood and AppleJack slowly split in two.

“APPLEJACK!” Rarity said with a blood curdling scream.

“RUN!” Pinkie Pie shouted. The girls then turned to run out of the house. Cadence used her tendril to strike Gloriosa in the back of the neck. Gloriosa was then lifted up into the air. Her eyes rolled back as the purple tint covered them.

As the girls rushed out of Twilight’s house, Sunset tripped and fell.

“Sunset!” Fluttershy called back.

Sunset got up to her hands and knees. “Go! Get to Princess Twilight! Only she can hel-”

Twilight then emerged behind Sunset. She sent her purple tendril right up Sunset’s ass. Sunset inhaled sharply as a thick goo dripped from her mouth.

Fluttershy, Rarity, Pinkie Pie, and Spike were all able to get away. Twilight, Cadence, and Rainbow Dash Joined Sunset and Gloriosa on the front lawn.

“How do you like your bodies?” Twilight asked.

Both Sunset and Gloriosa felt up their bodies and smiled.

“These are perfect!” Gloriosa said.

“Nothing will stop us from bringing the darkness!.” Sunset said. All of the girls then smiled as their purple eyes glowed in the night.
