Chapter 1: Control

In the small darkness of the lights of a lab, mixes of many things; scientific ingredients that no one would be able to pronounce except for one person... Twlight Sparkle, the only one diving so deep into researches that could potentially create something unspeakeable for many.

Inside a glass container there is a strange substance that has the mixes of red and black that never mix between each other. Twilight had a small gap open on the container and with carefull approached an electrode to the substance and shocked it for a breef period of time, just to close the container after it. After that she placed the container on a table and approached a finger to one of the borders... the substance, reacted and displaced towards where her finger was. Twilight smiled after seeing her success.

"It's alive..." She mumbled. "IT'S ALIVE, YES!" Screamed all over her lab and jumped of happiness all around the table. "It took me nearly two months, but i finally have done it" Then her joy was suddenly cut by the door bell.

Sunset Shimmer was just waiting for Twilight to open the door, they were suposed to meet at a cafeteria... about an hour ago, Sunset was just tired of waiting so she came to Twilight's house. Just a few minutes it's what Twilight took to open the door for Sunset.

"Better later than never, i've been waiting for you for a long time, Twilight" Sunset's voice had obvious upset tones. "What where you doing?"

"Oh... it was today?" She literally admited that she forgot. "My bad Sunset, sorry. It's just i've been working on something very important" She showed the container to Sunset.

"It's... Watermelon chewing gum?" Sunset joked about it's colours, makign Twilight raise an eyebrowse. "I'm sorry... haha, it's just that it looks a bit silly. What is it anyways?" Sunset said it between small giggles

"Very funny, this is an actual life form that took me long to create. I still have to find a solution to some weaknesses it has like loud sounds and fire but i think with this i can make something to help with modern medicine" Twilight explained to Sunset, who did not understood any of the words Twilight said, but she looked so happy that didn't wanted to interrupt her; except for one little thing.

"Hey Twilight, i'm sorry to interrupt you... but i need to use your..."

"Say no more" Twilight placed the container on the table. "First door on the left, i'm sure you remember"

"Thank you" Sunset run throwing her bag in the table, opening when it landed; spreading all of her things all over the table. Meanwhile Sunset was in the bathroom, Twilight cleaned all the mess Sunset did putting all her things inside the bag. "Twilight, i may have to go just as i get out of here. I have to study for something"

"I can help you if you need" Twilight offered herself, not paying attention for a second on what she was putting inside the bag; so she put inside the container without realizing. "You know i'm a great studying pal"

Sunset went out of the bathroom and grabbed her bag. "I'm thankfull, but this is out of your reach. I guess you do know about programing related to gaming?" Sunset asked but Twilight just negated with her head. "I knew so, see you later... and by the way, i would take a shower; your lab clothes smell a bit" Twilight checked as soon as Sunset leaved the house, shutting the door behind her.

"She's right... well then; today i made a good work. I'll take that shower and go to sleep" Twilight went directly to the upper floor, still not realizing what she have done.

It's almost 12 Am, Sunset is still studying but her eyes can barely stay open towards the bright screen with the multiple lines of code. It was not ok to keep studying so she shutted down the computer and after a small rest on her arms she standed up and put on her pijamas. On her way to the bed she accidentally dropped her bag making again to all the things inside to spread over the floor.

"Ugh... i'll clean it tomorrow... now i need some rest..." She walked slowly to her bed and just fell straight to it sinking into the mattress and almost falling asleep as soon as she changed to a better position.

Hours passed, something is moving underneath Sunset's bed, slowly getting closer to the mattress... it was that strange substance that finally reached the top of the bed, it crawls slowly closer to Sunset until it reached her feet. Sunset was wearing sock, but the substance did not cared about it covering it and pierced the fabric as if as a liquid it was... touching Sunset's foot.

The warmth of Sunset's body made the substance grow and climb up the leg; Sunset was feeling it, but as she was just tired she just started dreaming about someone touching her shamelessly. As soon as it reached her pussy, it went inside spreading too on her insides and the other leg; Sunset started moaning.

The thing could be seen moving upwards Sunset's body, the pijamas were moving as it were going up and inside every hole it encounters on it's way; at that moment... her asshole. Sunset's moanings were getting louder as it kept growing, covering her breasts competely, reaching her arms and growing on them; making Sunset grab onto the sheets and make even louder moans. It reached the face, as soon as Sunset opened her mouth again it crawled inside it, spreading even more on her insides; Sunset's body arched of pleasure and squirting all over her bed... finally the thing covered her whole head and with all the spreading on Sunset's insided it took control over her brain.

She stopped squirting and arching, the thing molded itself as Sunset's body, but also making some other changes on her that no one could see until it would like to. The eyes opened, it walked down the bed and faced itself into a mirror... when the light was turned on, it was still Sunset's body... but not Sunset's mind, the thing was still crawling on her face makin space to look itself on the mirror.

"We... look... great!" It said with Sunset's voice, it took off Sunset's pijamas and rubbed her hands on the body. "Such strong feelings, she has the perfect feelings for me... or she had them, but they're still here; with us" The thing giggled while still admiring the body it took control over. "What's this? Friends? One is our creator... well then, we think we can get a bit selfish and spread myself a little bit more" Claimed as it's goal, just to then start laughing as loud as it could... Twilight, what have you done?

Author's Note

For some reason Marvel is not a crossover; this was initially an idea for a Symbiote story but since that wasn't a part of the things i could chose from, well i made it a mistake made by Twilight. This will be a shorter story, with just the chapters i have planned. I hope i can develop it a bit more.

Chapter 2: Flying Feel

"Remember, we must not be found. When we're in sight of others we must act like nothing happens" The thing said to itself before focusing to make clothes, something more fitting with it's mission of spreading... it choosed, leather boots, red lace stockings with garters, an almost non existant skirt, no underwear and finally a black leather jacket with another red shirt. "Now we're gonna catch some of those friends with this, for sure... time to catch a prey!"

It stepped out of Sunset's house, the feel of the air and the sun on the skin made it feel comfortable but also hungrier for pleasure and power, the only thing that it wants for living and for feeding. It knows what it wants and knows exactly how to get them; as it watched on Sunset's memories about her friends and what they do and like to do.... it will use those memories for itself.

It was walking down, checking Sunset's phone to see who was it going to catch first. It had an idea, but had to make sure that no one could find it spreading itself on more alive beings.

"Sunset!" Twilight yelled from behind. "Good morning! How was your study session"

"It were great, but felt tired and went to sleep very soon. You know boring studying things" Sunset answered, trying to keep it cool and disguising it was the thing that was talking for her; not that she has another choice but let it have the full control.

"Well, at least you have it under control" Twilight answered before checking Sunset up and down. "Wow, Sunset; i didn't knew you liked this kind of clothing. Isn't it a bit too... revealing"

Sunset cleared her throat. "Listen, Twilight; sometimes a woman just wants to show her true self and this is my way to show my own self to the world" Said with a convincing tone and a small wave of her hips. Twilight watched those hips wave, before her phone rang, to amke her check who was.

"Oh sorry, i have to go. I have to go see my brother and Cadance; see ya later" Twilight waved and run away, Sunset waved back but her face changed to a full annoyed face.

"We fucking hate you" It said before going back to the phone and look for it's prey; who already was selected as soon as she checked the phone again. As it has control over Sunset's body now it can move faster and can last longer on running, basically can't get tired anytime soon; and with that as a blink it reached it's destination and knocked at the door... staying there until it's prey opens the door.

The door opened slowly, letting the sun go in even more slower. "Sunset?... why are you here? it's.... too early" Fluttershy said between yawns, she was only wearing a shirt with her right shoulder completely uncovered, her nipples were visible through the shirt and also pink panties were at sight.

"Sorry i came without saying anything, but i need some help with something and i was hoping you could help me out" Sunset's voice was calmed, enough to make Fluttershy want to help; but that was not needed as the girl was practically recently awake.

"Well ok... come in, but... i may not make too much attention to you" She letted Sunset go in and shutted the door; it looked at Fluttershy's body from head to toe and licked her lips. Fluttershy yawned again. "So... what do you need help with?"

"We need help with..." it grabbed Fluttershy from the crotch and then the shoulder and pulled her closer to it. "... this!" Fluttersy felt the grab and that woke her up instantly. Fluttershy turned her head a bit and looked at Sunset, who's clothes were changing from what she was wearing to what it looked like a red and black latex body suit with her teeth more sharpen than before, as it could be seen as it was smiling... wide open.

"S-S-Sunset?!" She was petrified with fear, that was not her friend; she could tell about it, it's strength was not normal. In just a blink she was pushed against the floor with Sunset at top of her with a menacing look in the eyes. "Y-you're not Sunset... what do you want from me?" Fluttershy asked, trying to force herself out of the control of the thing.

"Sunset is here, with us. Don't worry, i won't hurt you... i just want a kiss" It leaned it's head closer to Fluttershy's; who just wanted to look away but couldn't... Sunset's body reached to kiss her, Fluttershy did not follow the kiss as she was being forced to do it. Then, Fluttershy felt something pushing to her mouth, it was a tongue that it was making it's way through the lips, Fluttershy thought that it would only play with her mouth, but no... the tongue continues the way to her throat until Fluttershy was starting to choke. It leaned the head up and with that the tongue came out of Fluttershy's mouth who coughed hardly. "Tasty... yes, you will have a good use to our plan" It claimed looking at her

Fluttershy kept coughing a little more, and then she felt like she was flying. When she recovered a bit saw that the thing had some sort of tentacles attached to the ceiling to make them go up, then it put 2 more tentacle things on her wrists and ankles and ripped her clothes exposing her body. "P-please... just let me go" Fluttershy asked but her voice wasn't strong enough to make it stop... not at all.

"Cease your fight, we'll take control on you. Forget about all..." It prepared it's crotch and placed it against Fluttershy's "... and feel like you're flying" It started to rub both of their pussies together, as fast as it could; making Fluttershy's body feel warmer; it started spreading on Fluttershy's body, inside her pussy and up her waist, slowly crawling to the scared woman's mouth, she saw it getting closer keeping her mouth closed as much as she could... until a moan escaped her mouth, with that open, it went inside her mouth; now it could reach her braind and submit her.

As it started to take control over Fluttershy, her body shakes for a brief period of time until it stopped. The tentacles that were keeping her wrists, detached freeing them; the first thing she made when having her hands free was holding her breasts squishing them. She also got the same sharp shaped teeth and long tongue, they both looked at each other's eyes and kissed while introducing each other's tongue inside their mouths and throats. As it was also inside Fluttershy's body, she was now able to not choke, so she could have it as deep as humans can't take it, that heat she was feeling helped for it to cover all of her body... once she had it covering completely, both of them squirted and screamed of pleasure.

Fluttershy was still herself, just a puppet under the control of the thing that controls Sunset, it grabbed Fluttershy from the chinn gently and looked into her eyes. "You will not spread to others, you will listen to my call. We're the only ones that will spread... so you will still act like you always do, but a little more hot than before. Understood?"

"I understand" As she answered, both of them were back in the floor, it turned her clothes back to the stockings and leather boots and jacket, Fluttershy stayed with her new form a bit longer and pleased herself a bit more. Then it left the house and walked back to home so could plan the next move.

"Maybe being this aggresive is not ok" it thought to itself. "Maybe for the next one i can use some other tricks" With one down, it gained a bit more power and after this encounter now also knows what it has to do to not call attention even more

Chapter 3: Let it Rain Over Us

With one down under it's control, it immediately started to look for its next prey and had one in mind. About 3 PM she reached her destination but this time she didn't needed to ring the door bell as it's prey came out almost as she put a foot in her front door.

"Well look at that, Sunset's here" Applejack grabbed her by the shoulders. "Just the girl i needed, come in"

"Umm..." Before she could answer, Applejack pulled her inside the house. She made Sunset sit in a couch, and quickly went to the kitchen. "Aj? What did you said you needed me for?" She asked, higly confused about what was happening. Applejack returned with two bottles in hand and placed them on the table in front of them, Sunset grabbed one and gave a quick smell to it recognizing the esence. "This is an alcoholic drink?"

"It sure is, since i'm currently alone here i guessed this was the best way to spend the day" Applejack looked at Sunset deep in her eyes. "Just two girls and two bottles of cold but a bit acoholic drink, wadaya say? Pretty good plan i had"

For a moment it gulped, it knew that Sunset had a low tolerance to alcohol but didn't knew how would affect it now that has the control over the body and mind. It saw Applejack drinking almost half of the bottle in one go, it was not bigger than a soda bottle but it was alcohol so it was a bit harder to drink it. "Ok... here i go" It said before grabbing the bottle and slowly drinking it's content until reaching the same point as Applejack.

"Takin' it slowly? Is it to strong for ya?" Applejack teased Sunset.

"Strong? Ha, not... not at all. This is nothing for me" It answered trying to look tough. "Like drinking water"

Applejack smirked for a second. "Ok then, i think i should bring the strong weapon" She lead the way to a room, and opened a small drawer where she pulls out a bigger bottle of alcoholic apple cider. "Say hello to the Blacksmith, it's called this way because one drink of this is like being hit by hammer" Applejack claimed while it gulped one more time after seeing it and the ammount of alcohol it had. "What? Are ya scared?"

It took it personal "You dare to challenge us... me? Fill me a cup" It asked with a slight anger tone in the voice. Applejack did not filled just a cup, but two cups; one for each. They both grabbed the cup and take drank it in one go.

As Applejack said, it was like a hammer, and with that she felt a bit bad; her body felt really hot and placed a hand on her crotch. "W-what? Just from that?" Applejack wanted to go to the bathroom but Sunset's hand grabbed her. "What in the... Sunset?!"

"Hello there big butt!!" Sunset's face was completely red and it's eyes looking at Applejacks butt. It raised AJ's skirt revealing pure white panties. "It looks tasty" especially between these thighs you have"

"S-sunset, cut that... i need to... pee; i can't do it here" Applejack tried to make Sunset stop, but she quickly saw that she was actually really drunk, like it drank the whole bottle. She had no strength to push her away because all of her focus was in her crotch, keeping the pee inside of her. Applejack gave up, she knew it was nonsense to fight with someone that is drunk because they act like knucleheads. "F-fine... do whatever ya please, but if we make a mess you're goin' to be the one cleanin' it later"

"Oh, don't worry..." Sunset's clothes were starting to disappear in slimy strings meanwhile pulling down Aj's panties. "... we got it covered" Applejack didn't say Sunset's clothes disappear so she had no clue but was embarrased; then it started to lick Applejack's pussy from behind.

Applejack's pussy was highly sensitive, holding it in was making her crotch zone a very tingly area. her cheeks were turning more reddish as Sunset kept licking her. But then, Aj's body started to shake for a brief moment, it was about to come out. "S-sunset; it's comming out... i can't hold it"

"It's ok, let it rain over us!" Sunset prepared and opened the mouth, and then Applejack started peeing on Sunset's body. That warmth was it needed to unleash the power, with both it's hands; Sunset grabbed Applejack's hips and sticked her tongues inside her pussy while she was still peing. Applejack stopped peeing but it already infected her insides and now that it's warm it is starting to spread inside Applejack's body.

"What is this... feeling?" Applejack felt it growing inside of her; slowly heating up her body. "I need to get undressed" She took all of her clothes off, but the heat was not stopping. Her hand moved by itself to her pussy and started fingering herself, when she looked back at Sunset she saw her with the red and black slimy strings covering her body slowly. "What have ya done? I don't want this! This feels wrong" Applejack had thre fingers inside her pussy, she said that it felt wrong but she was indeed enjoying that.

Sunset put Applejack against her back on the wall. "Kiss us naughty girl" It claimed, opening it's mouth and showing the long tongue. Applejack couldn't think and opened her mouth, the tongue went inside Applejack's mouth and throat making her eyes to roll blank; as soon as Sunset's breasts touched Aj's it started spreading on her body, slowly taking control, slowly gaining another puppet until then.... Applejack's body and mind were no longer of herself. "Such a tasty prey you were and oh... what's this? Interesting memories you have"

Applejack now was like the thing, just like Fluttershy, sharper teeth and long tongue, with the slimy thing able to turn into her normal clothing. "What is yar command?" Applejacks asked, while still maturbating over the heat she was feeling.

"The same as the other puppet i have. Don't do anything, act like normal; we will call you when needed" Then the thing feeled a sudden headache, the alcohol stopped to make effect; the quickest hangover ever. "We should clean this and rest... tomorrow i'll get my next prey and it's thanks to you that now i want her" It smiled wide open showing her shapt teeth.

Later that night in Twilight's lab...

She's nervous, looking everywhere around the lab looking for her expertiment; but nowhere to be found.

"Oh no... Where is it?! I haven't tested it yet" She kept repeating to herself, thinking that saying that will help her to find it quicker. Then she looked to a window with the almost full moon in the sky. "If that is outside... then i'll better hurry and find it before it causes troubles. Dang it, next time i have to test more the stuff i make before losing them"

Chapter 4: Rougher, Faster...

The following day, Sunset's body has recovered completely from the hangover it had after drinking that small cup of 'The Blacksmith'.... never again, it's what it thought to itself. Today was another day, but the same clothes were chosen for today; it had a plan on someone thanks to Applejack memories she read after taking control over her. One final look into the mirror checking how hot it looked and steped out of the house looking for it's next prey.

The sounds of steps, running down the streets are everyday's sounds; athletes doing their daily routine to have an overall healthy lifestyle. One certain runner has ended her routine and sat at a bench to take a deep drink of her water can, drinking most of it as possible in one go. "hah... now that's what i call dashing! Heh, i'm good at this" Rainbow Dash showed off to herself even when no one was around to hear what she said. "And... i'm talking to myself again"

"Well, not exactly to yourself alone" Sunset arrived from behind, almost like she did no sounds when stepping closer. "Did i catch you in a bad moment?"

"Oh hey Sunshim! You didn't. I just finished my morning routine, take a seat with me" She offered to Sunset, while cleaning a bit of her sweat with her arm. Sunset sat aside Rainbow Dash, who's skin was shiny with all her sweat running down her blueish skin. "So, you got anything new happening in your life?"

"Well, there is actually... one thing i've been wondering lately"

"Ooh... tell me about it. I want to hear it" Rainbow Dash took another drink from her water can.

"Ok... what's the feeling of kissing another woman?" Sunset said making Dash water go into the wrong duct making her cough and look at Sunset with the corner of her eye.

Rainbow Dash laughed nervous and cleaned once more the sweat from her forehead. "How am i gonna know?... I just... kissed guys and... i haven't done with women" She claimed before giggling again nervous and drinking a bit of water; it was very obvious that she did it before but for some reason is trying to hide it. But then Sunset leaned closer to Rainbow's face.

"Would you like to try with me?" She said to Dash directly into her ear, making the sporty girl to blush a lot. "Or is that... you don't find me attractive?"

"Is not that... you're very attractive; but we can't just kiss here all of sudden" Rainbow Dash was caught off guard, she wasn't expecting that from Sunset at all; but after checking her new outfit she kinda couldn't take her eyes off her... she was eating Sunset's body with her eyes. "Well, you know my place is close... so... i guess we can go there and do things"

"I like that idea" It smiled, it got what it wanted. Reading Applejack's memories were the best thing she could do, as now she knows that Rainbow Dash despite being tough she likes to be dominated by other women. They went to Dash's place, and went inside as quick as they arrived, once inside the house was looking really dark as the blinds were still not open.

Rainbow Dash closed the door behind her and walked closer to Sunset, who she grabbed from her cheeks and made her look into her eyes. It noticed that Rainbow Dash had her eyes slightly closed and a feeling of lust were growing inside of her. "You're mean, Sunset" She said with a sensual voice and holding her from the waist with one hand. "These clothes you wear... you knew exactly what you were going for, didn't you?"

"Dash? Are you ok? This is a bit-" Sunset got interrupted by Rainbow Dash, she was kissing it and holding her close to her body. It wanted to take the iniciative and submit her; but Dash were the one that took the lead, kissing and groping one of Sunset's breasts. She stopped to take some air and started to undress throwing her sweaty clothes into a chair that was there close to them.

She was only with her panties left, she took them off slowly and once they were off she placed them on Sunset's face; with it's nose placed where the crotch were. "Give it a good smell, meanwhile i may make sure that you also feel good" She kneeled before Sunset, running her hands down her body and pulling up the skirt Sunset had, revealing the sweet pussy. "Hello there sweetie, time to eat" Rainbow Dash did not waste any more time and started to lick that pussy provoking Sunset to moan.

It was astonished by Dash's performance, it's what it expected from another possible puppet, but it wanted the control; it wanted to take control over her. So with a push it made Dash lay on the ground on her back, then it placed on top of her and taking off it's face the panties. "You... have no idea what you've run into" It leaned over and started licking Rainbow's body, tasting the sweat she still had on her body, her belly, her breasts and her neck. It smiled with it's sharp teeth to Rainbow Dash and changing her clothes to her ussual slimy body-suit. "Tell me Dash, if we came closer to you looking like this... what would have you done?"

"Wow, is that some sort of equestrian magic?" Dash asked blinded by it's lust

"Huh?"

"Are you gonna use those powers on me or what?" Rainbow Dash spread her legs for Sunset and her eyes were just saying 'Fuck me'. It really wasn't expecting this turn of events, but was happy to see that she was willing to be taken by it's powers; with the permisson of Dash it started to rub both of their pussies together while using it's long tongue to wrap it around her
breasts. "Fuck yes! That's what i've been waiting for... go rougher"

"Your wish is our command" Sunset's body moved faster and pushed harder against her pussy and grabbing her legs so she could do it way faster than with its hips. Then the thing remembered something, a thing that it could do. With a little bit of concentration it managed to create a hard, meaty and throbing cock with it's slimy substance... calling the attention of Rainbow Dash. "You want it, it's yours... but you'll have to submit completely to us"

"Oh i will, i will submit" She said while getting closer to the cock and use her hands to care it with the eyes not losing any details from it. "So big, so... perfect. I want it so badly inside my pussy" Rainbow Dash sat on her couch with her legs spread and holding them with both hands inviting Sunset to go in. It walked closer and rubbed the tip on Dash's pussy, noticing it was wet enough it pushed inside. "Ahhh!" Dash moaned after feeling it going inside.

The thing moved it's hips as fast as it could do, making Raimbow Dash moan with each thrust. It was certainly tight, but lubbed enough with the pussy juices so it can go in and out very easy. The sounds of the wet pussy being pierced by that cock filled the room alongisde Rainbow's constant moaning. The thing was also moaning loudly, the feeling of a having cock was something that Sunset didn't experienced, either having one inside or having one that was of herlself.

Each thrust helped for it to spread inside Rainbow Dash, her body was not trying to fight back as the lust took over her really quick, it was spereading quick in her insides as the lust and warmth of her body was already perfect. The thing felt all the pleasure enough to feel like cumming, so it faked a cumshot inside Rainbow Dash's womb.

As soon as the cock was pulled out of Dash's pussy, it started to grow outside of her body; she was still horny about all. "S-sunset, could you please repeat that but on my butt?" She turned around and raised her butt.

"Of course, how to not please you more?" It rubbed again the tip against the butthole and saw the slimy thing covering up higher on Dash's body, it waited for a moment until it started to push it. "And... now!" Pushed inside, made Rainbow Dash to open the mouth making it crawl inside her mouth and spread more inside and got to reach once more the brain.

Rainbow Dash pulled out her now longer tongue and kept moaning louder and started to squirt all over the floor thanks to the feeling of the cock inside her butt. It thrusted even faster and faked another cumshot inside of her. "T-this is not enough... can we continue for a bit longer?"

"Of course, we'll please you as you need. Then we will tell you what your orders will be" They both prepared for many more hours of pleasuring, symbiotic sex... the next prey could wait, it had to please one really horny puppet for as long as possible.

Chapter 5: Bunny Bounces

After many hours of pleasuring Rainbow Dash and giving the instructions it gave to Applejack and Fluttershy too; now wlaks looking for the next prey. Surely wasn't expecting dash to be such naughty girl when it comes to do sex, but what about the one that is always wearing fancy clothes? The one that is always doing new outfits for their friends over and over, acting like a lady in front of others but secretly may be very naughty and slutty... probably.

It went directly to Rarity's place and rang the door bell; checked the phone to pretend that was doing something important with it. The door slightly opened making a cracking noise. "Sunset... come in, quick!" Rarity said from inside, Sunset went inside and closed the door, as soon as she put her eyes on Rarity the only thing she could look at were at her long slender legs covered in black pantyhose; Rarity was wearing a bunny suit that looked sexy on her.

"Rarity... why are you wearing that?" Sunset asked just to be polite and to know the reasoning behind Rarity's strange clothing.

"Long story short... laundry" She said before taking a seat on a chair and crossing her legs, when she did that the fabric of the pantyhose made a sound that made Sunset enchanted for them. "What can i do for you, darling? I hope it's something i can do while wearing this, because i don't have any other useful clothes"

"Don't worry Rarity, you won't need to change" That was the moment the thing started to plan what to do. "In fact, you're dressed perfectly. Have you heard what people say about bunnies?"

"That they're cute and that they eat really funny?" Rarity answered clueles, sometimes she does this.

"No, Rarity" It placed two of it's slimy strings in Rarity's wrists, she didn't expected that and Sunset's voice tone was kinda scary for her. "They say, bunnies have a really high sex drive... and we're going to find that out" It smiled showing Rarity's the sharp teeth, which definetly scared her out.

"W-what?! No!! You can't do that" Rarity tried to make Sunset rethink, but she didn't knew is that Sunset weren't the one in control, it removed Rarity's heels uncovering her feet that were covered with the pantyhose. It used it's longue tongue to lick both of the fabric covered feet at the same time. "Ugh... that's disgusting! Wetting pantyhose with saliva? You could have used water!" She spoke her truth, she didn't liked Sunset licking her feet, but the thing didn't cared and kept licking them for a few more seconds.

After licking her feet, she stopped and changed the clothes in front of Rarity, to it's slimy bodysuit and it's fake cock throbbing for the excitement of going in. It pushed it against Rarity's lips, but she turned around her face; but with both hands it grabbed Rarity's face and forced the cock inside her mouth provoking tears to ruin her make up. "Yes! We're pleased by this" it claimed while thrusting the hips, Rarity were doing gagging sounds; she wasn't understanding what was happening but she certainly didn't liked it.

It pulled out the cock out of Rarity's mouth, who coughed. "You... monster!" Rarity claimed with anger before looking back at the thing. "Doing this to a lady; where are the manners?"

The thing grabbed Rarity by the cheeks. "You tell us about manners while dressed like this?" Inmediatly after, it laid on the gorund on it's back and placed Rarity at top of the cock; the suit created two strings that grabbed her by the thighs and pulled her down to the tip of the cock. "Come on bunny girl, bounce for us"

"No... please... Don't..." She was still being pulled down until it went inside, ignoring the clothes she was wearing; more tears were going down her face and... one moan? Rarity covered her mouth with her hands, she couldn't have enjoyed that.; but her body was infected already, making changes on her and her thoughts. The thing were moving it's hips making Rarity bounce constantly on the big cock that was reaching her womb, Rarity's eyes were showing fear and her body were heating more and more as for each thrust.

The thing's thrustings made Rarity's whole body bounce, like little bunny bounces; which cause Rarity's breasts to get exposed out of the bunny suit. It went faster with each hip thrust until finally faking the cumshot and making Rarity's mind to go blank for a moment, a few seconds later the slimy thing crawled out of her pussy and started spreading on Rarity's body; which made her recover and feel good, great and in full shape for more; with her new granted long tongue she wrapped it around the cock and licked it. "You want more of us little bunny?"

"Yes... i want more" She got on top and rode the cock by herself, each jump she made was making her even hornier; with the new slimy bodysuit her boobs looked like they were bouncier than before. Rarity started to play with it's boobs while not stoping from moving her hips up and down; they both were moaning filling the room with their screams and wetty sounds. They continued until Rarity squirted all over the thing, they kissed for shuting their noises and because kissing is another way to keep their warmth.

It explained what her plan is, another puppet joined and it feels powerful and lustful; needs one more puppet and it's lust would be unstopable, enough to submit anyone under it's power by just a simple kiss or thrust of her genitalia. Just needs to text the right person and set everything for the big day... or night

Chapter 6: The Sleepover

The sweet smell of a recently baked cake filled a room; it as ready a cake that took nearly some minutes to make; classic Pinkie Pie things, baking something in about a few minutes even if it should take some more time. Pinkie then got a text from Sunset; the reason... a Sleepover at her place. Pinkie went directly into sleepover mode, grabbing snacks and some movies for the night; she will make sure that in that night no one sleeps... and that is kinda Sunset's or the thing's plan.

Later as soon as the night came in, Pinkie arrived at Sunset's place and rang the door bell. Sunset opened the door as soon as it rang leaving full view of the party girl with a very wide smile on her face. "I'm here, now we can start the thing!"

"You're on time, everyone's upstairs. Come in! Feel like home!" It invited Pinkie with a small smile not showing the sharp teeth. Pinkie came inside and went upstairs to Sunset's bedroom, indeed she found everyone there but Twilight who there was no sight of her anywhere.

"Sunset, where's Twilight?" Pinkie asked

"She's bussy, scientific stuff that she has to do"

"But she could be having fun with us...." Pinkie got a bit sad from it, but recovered quick. "I'll call her over"

"NO!" It screamed, making Pinkie suspect a bit. "Sorry for that scream, we did called her but she insisted on not comming; what she's doing it's really important for her"

"Oh, i see. Ok then; if it's that important then let's have fun! I bringged a lot of snacks" She run where all her friends were and sat alongside them, but she didn't had a clue that none of them were as they used to be. It smiled and showed the sharp teeth to then lick her lips; to not call the attention it joined all of them with the snacks, the movies and the music.

Most of the time were laughs and jokes, some good and some really bad. There was fun, but not all the fun that was intended. A strange aura filled the room, but Pinkie didn't noticed by all her laughs and jokes. "Girls, i think it is time for our especial 'fun' plan. What do you say?" It claimed, all girls nod except Pinkie who didn't knew what that especial fun plan was... until she heard a smooch, Rainbow Dash and Applejack were kissing just right next to her and rubbing their boddies from outside of the clothes.

Another smooch started, Fluttershy and Rarity were doing the same thing as Dash and AJ; Pinkie turned red as she wasn't expecting this to be that kind of Sleepover; she hold her cheeks a bit embarrased of the scene she was involved into. She leaned a bit back and the back of her head hit something squishi and bouncy... Sunset's boobs. "S-sunset...?! You didn't told me about what kind of Sleepover this was"

"Are you disapointed?" It run her hands down on Pinkie's body until reaching her boobs and squishing them.

"N-no... but... you could have... told... m-Ahh" Pinkie moaned after feeling Sunset's hands on her. It pulled her head a bit more so they both could kiss, Pinkie closed her eyes to feel that heavenly made kiss. As soon as she closed her eyes, everyone's clothing started to disappear on red slimy strings and transforming into the slimy bodysuit. Pinkie felt something o her knees and wrists that prevented her from moving, when it stopped kissing her Pinkie saw the truth... everyone covered in a strange slime suit, sharp teeth and inhumanly longe tongues. "W-what is this?!" Pinkie asked.

"Don't worry darling, just submit to it" Rarity said before holding on Pinkie's right leg.

"Yeah, this is something we all love now" Fluttershy hold into the other leg.

"You've got ti feel it Pinkie, it's great" Rainbow Dash kissed PInkie's neck.

"Ya just need to... relax and get warmer" Applejack standed at top of Pinkie and after rubbing a bit her pussy, she started peeing on Pinkie's pijamas; making sure that if she wasn't wet naturally... she would be wet and ready.

"Girls, please... don't be so rude with her" It said, it was crawling on the ceiling and slowly descended in front of Pinkie Pie, Rarity and Fluttershy kept Pinkie's legs spreaded. It created it's fake cock, but now it was even bigger than before, reaching Sunset's cleavage; it walked closer to Pinkie and once it was on it's reach... they ripped her clothes out of her body exposing her pussy. "Now, that's welcoming"

"W-wait... there's no way that would fit at all! Stop please!" Pinkie begged

"We've seen you pulling bigger stuff from your hair... this will be nothing for you; trust us" It pushed it's way inside Pinkie's pussy, not a sound from her mouth but every inch it was going inside... the more Pinkie's body were arching. It kept pushing inside until locking itself inside Pinkie's womb. "Let's get this going" It started to thrust it's hips against Pinkie's crotch slowly to not hurt her.

Pinkie didn't said anything, her mind was blank, just a few tears down her cheeks; it felt painful but for some reason now it was feeling more pleasuring. Meanwhile it was thrusting it's cock, the rest were using her tongues to lick Pinkie's body taking care of the sweat she had; all those licks made her body be covered in saliva making it shine and be slippery. It leaned over and rub it's breasts on Pinkie's body until the nipples were tocuhing each other.

"Kiss us, party girl" It asked opening the mouth and sticking the tongue out. Pinkie gave up and opened her mouth, it kissed her and introduced the tongue as deep as it could inside Pinkie's throat. The thrusts became more aggresive, faster and ready to spread inside of her; so it moved as fast as possible and faked one last final cumshot filling her womb. It pulled out so it could spread on her body, and it did... crawling out of her pussy, covering both her legs, her belly, her arms, breasts and going inside her moth to take control of the brain... once done she let out all the moans she repressed while getting fucked and even squirting hard although the cock was no longer inside of her. "Yes, this is what we wanted... just a bunch of horny women, lusting and craving for more and more pleasure... well then. Let's have the most pleasuring orgy we could ever do"

It claimed, everyone were feeling their bodies getting warmer and warmer; nothing but lust in their thoughts and them just needing pleasure to live and to give their lifes for; they all crawled around the thing and standed with their asses up ready to take everything.

A car stops outside of Sunset's house, and inside is Twilight Sparkle who brings a big backbag and her most serious face ever. She closed the car and standed in front of the house before taking a deep breath. "Ok, show me what you got... you slimy failed experiment" Twilight walked closer and placed a hand on the door and opened it slowly; this has to end...

Chapter 7 (Final): Bring it on!

Just a few days back...

Twilight is taking a shower, the hard work of making a fully functional experiment made her forget about things like the meet up she had with Sunset or to take care of her sweat, so now she's taking care of one of the things she had on a to-do list. She used the shower to pee a bit, and no one was going to say to her to not do that; it was refresing, but another thing was on Twilight's mind... Sunset, her and how the skirt she wears makes her thighs look big.

"S-sunset..." She moaned her name as she started to sub her pussy with her middle finger. "Why you have to look that hot?" Twilight's body were heating up imagining that was Sunset who was touching her pussy lips and clit, moaning a bit more and letting lust grow on her. Then her phone started to ring, snapping her out of her erotic fantasy. "Twilight Sparkle, you should stop fantasizing about these things in the shower" She though to herself before stepping out of the shower to answer the phone.

The next day, Twilight is walking on the streets going straight to her brother's house; it's been a few weeks since they last seen each other. On her way she spots Sunset, walking with stange clothing: a leather jakcet, a very short skirt and stockings... lace stockings? Twilight knew Sunset would never wear something like that; but she looked hot and for Twilight's eyes she would love to be dommed by her wearing that outfit. She sprinted a bit closer to Sunset. "Sunset!" Twilight yelled from Sunset's behind. "Good morning! How was your study session" Sunset stopped looking at her phone and looked at Twilight.

"It were great, but felt tired and went to sleep very soon. You know boring studying things" Sunset answered.

"Well, at least you have it under control" Twilight answered before checking Sunset up and down once again. "Wow, Sunset; i didn't knew you liked this kind of clothing. Isn't it a bit too... revealing" Twilight really didn't wanted to ask about Sunset's clothing, but it could be a chance to get her to do something with who she had a crush on.

Sunset cleared her throat. "Listen, Twilight; sometimes a woman just wants to show her true self and this is my way to show my own self to the world" Sunset answered with a convincing tone and a small wave of her hips. Twilight watched those hips wave distracting her for a brief moment, before her phone rang, to make her check who was calling her.

"Oh sorry, i have to go. I have to go see my brother and Cadance; see ya later" Twilight waved and run away answering to her phone. "Fuck, Sunset... you can't dress like that without wanting me to check you out; you sexy bitch just take me to your bed" She thought to herself while going on her way.

Later that night...

Papers flying, drawers being open and a lab full of desperation. "Oh no... Where is it?! I haven't tested it yet" She kept repeating to herself, thinking that saying that will help her to find it quicker. Then she looked to a window with the almost full moon in the sky. "If that is outside... then i'll better hurry and find it before it causes troubles. Dang it, next time i have to test more the stuff i make before losing them". She prepared everything for the research on the next day, there was no time to lose.

Twilight started looking for the experiment, but no clue where to find it; the streets, parks, nearby houses to Twilight's house but no... nowhere to find it. When walking close to Rainbow Dash's house, she heard something comming from inside, when she peeked from the window; she saw Rainbow Dash screaming of pleasure while being taken by... Sunset with a latex bodysuit? No, Twilight recognized the colours from that clothing... it was the experiment taking control over Sunset's body and despite how good and sexy she looked for Twilight's eyes with it on she couldn't let it do of more of that.

"I have to stop it... but it's been a day since i lost it" She though to herself. "If it's been a day, then the probability of it spreading to other individuals may be high... so i can't take care of one of them or it could sense it; i need all of them in one place; but how?" She knew that because of earlier attempts that despite failing she got some notes.

Close to the night, Twilight is still thinking about how she can solve this huge problem; doesn't know how big it could spread if given the chance. Then she got a text from Pinkie Pie, she said that everyone was there and was insisted on not contacting her; but she did as soon as had a moment alone in the bathroom; that's it, that's the right moment to act and to stop it from doing more damage to her friends or worse.

Twilight's car stops outside of Sunset's house, and Twilight brings a big backbag and her most serious face ever. She closed the car and standed in front of the house before taking a deep breath. "Ok, show me what you got... you slimy failed experiment" Twilight walked closer and placed a hand on the door and opened it slowly; this has to end... inside, almost silence; just the sound of moans filling the whole house, Twilight walked cautiously to not call the attention and all the ay up to Sunset's bedroom... as soon as she got vision of the room, she got shocked by the image.

All of her friends were covered by the slimy thing, lust were all over their minds fucking each other like nothing else matters. Sunset was at top of all of them masturbating the fake cock and in some ocassions peeing all over the girls. It spotted Twilight observing the scene completely blushed. "Oh!? It looks like we have an unexpected visitor" It said walking closer to Twilight undoing the cock just to show pussy lips as she would be naked. "Like what you see on us?"

"You took control over my friends, i should have never created you" Twilight confroted it, still her face was bright red as she couldn't take away her eyes from Sunset's pussy lips and breasts. "I'm going to end this"

"Oh really? How do you want to end this?" It used both hands to bounce the Breasts, Twilight's eyes looked at them instantly. She couldn't really concentrate and her body was getting hot and wet every second she stared at it, she had to fight the urge, but her mind had another plan.

"Ok... i won't fight" She said out loud to the thing with her voice slightly shy. "But could you at least let me... dress appropriately for this?"

"Sure... get yourself confortable for us; for all of us" It was really confident, it would have control over the whole group of friends. Twilight changed from clothes, she was wearing purplish stockings and a see through top and no underwear, her pussy was exposed; she was holding her hands on her back and her eyes weren't able to look at Sunset. "Look at you, what a cutie in those clothes" It claimed with everyone behind Sunset.

"I... have a suggestion, would it be possible?" Twilight asked and it answered with a simple nod. Twilight changed her face from shy... to pure anger. "Leave my friends.... ALONE!!!" She activated something with her phone, that was holding with both her hands on her back, the speakers on Sunset's bedroom started to do a very uncomfortable sound it wided it's eyes after hearing that awfull sound and noticing Twilight had ear plugs.

"You... bitch... tricked us?!" They all fell to the grounds as the sound was getting more and more intenset, but it negated to not fight, it standed up as it was slowly falling off Sunset's body and her friends, getting out of their bodies and merging on a pile on a side of the room. It leaved all of their bodies. "T-Twilighit..." Sunset spoke. "What is going... on?" She fainted on the ground.

"Don't worry Sunset, i'll take care of this" Twilight grabbed a device from the backbag she bringed and activated it. "You won't hurt anyone again" She threw it to the pile and it combusted quick leaving nothing behind.

It was finally over...

Epilogue

Sunset woke up slowly, her head was turning and her whole body felt like she was drunk for a week. Twilight was there taking care of her andher friends. Sunset was covering with a sheet and sat to have a better view on Twilight.

"T-twilight" She called the attention of the science girl. "I'm... sorry i caused such a mess and mind controlled them. I feel dirty after all that"

"Sunset, it was not yar fault" Applejack sat too. "Ya weren't the one in control and it was that strange thing the one that made you... and us do all that kind of stuff..." Applejack realized that she got her pee drinked, with that image inside her mind she just covered her face with her hat and didn't said anything else.

"Indeed you don't need to apologize, darling. We just got something we weren't expecting at all"

"We certainly weren't expeting that... at all. How embarrasing the things we did" Fluttershy covered also her face, while Rainbow Dash wistled to hide that she did it because she wanted it to and no because of mind control, she really was turned on by all that. Meanwhile Pinkie was just sleeping, deeply, as she was the most recently controlled she didn't had anything to worry about.

"Sunset... all of this happened because of me and my stupid impulse of creating things" Twilight sat in front of Sunset and looked into her eyes. "I created that monster and took contrl over you and made you act like a sexual predator with insatiable sexual desire. I'm really sorry"

"Twilight" Sunset letted go the sheet she was holding, showing her naked body and placing her hands on Twilight's shoulders. "You the most brilliant woman i've ever met and you did what you thought it could be a great discovery. I'm not mad, just a bit ashamed of myself" As soon as Sunset finished that sentence, she looked away from Twilight and fixed her hair a bit to lead the attention to something else. "Speaking of ashamed... how are you not ashamed of wearing something like that?"

"Huh?" Twilight looked down, she was still with the see through top that showed her nipples, the stockings and the absence of underwear that would cover her pussy. Her face turned way too red after noticing that she didn't changed her clothing after taking care of the thing. "I... i can explain!" She said with a very nervous voice tone.

Twilight started explaining everything while Sunset was just listening, also being naked but she didn't noticed at all. Outside of the house, the sound of the crickets fill the calm of the night under the shine of the moonlight and the starlights... but something is coming out of a bush, a little portion of the slimy thing has survived... it knows it can't go again with them, as soon as it tries to take control on any of them will alarm them and make story repeat itself; it's crawling slowly... it will find another host to spread it's lust again...
