Flutterbat Returns and Only Twilight is Pleased
Sometimes - a lot of the time, Fluttershy really wished that Twilight would ask and respect her consent when it came to her experiments. She wouldn’t. She knew that. They didn’t call her a “Mad Scientist” for nothing. At one point in her life, Fluttershy might have defended Twilight from that title. But no more.
The last one was… well it was no more brutal than usual but the fact that it had to include her was the last straw!
She used magic to force Flutterbat back to the surface and then set up the Apple family as “test subjects”. To see if her instincts would see them as apples. Big Mac was the control. The most apple-like. He was put under heavy tranquilization. The other three were hung and… the less said about how they were treated the better.
What was discovered was that her “other side” could differentiate ponies from apples. But it still pushed her to drain them all the same. Mac was drained in… two ways which had unforeseen side effects.
She looked between her legs and sighed. She was luckily tall for a mare so it didn’t look so out of place, but, lo and behold between her legs sat flaccid and currently unexcited was Big Mac’s Cock and balls. It wasn’t just exactly like them. It was them. She was conscious of the entire “experiment” and distinctly remembered pulling away from him. Pussy dripping with copious amounts of cum while his blood dripped from her lips and as she pulled off him, his cock disappeared and reappeared on her crotch.
She would then proceed to use that very cock on every one of the Apple family. Mac’s barely alive body included.
It was so embarrassing! Luckily most of them were in various stages of unconsciousness but she couldn’t look Apple Bloom in the eyes for a while.
At least Twilight was able to bring everyone back to normal for the most part though… according to AJ Mac was noticeably smaller now. Another long term side effect of it was Fluttershy herself. She kept the dick, the fangs and her ears were more fluffy now. Even one of the butterflies of her cutie mark had stayed a bat! She’d more or less merged with the Flutterbat side of herself now and she could feel or, hear that side of her pressing urges on her. The desire to drain others and herself into others.
Luckily, when she’s not being outright insane or cruel, sometimes Twilight has good ideas. So she offered an idea that Fluttershy donate her seed. There wasn’t so much she could really do for blood at the moment but donating her seed did some good at the moment. She was also sure that Twilight was tracking those who ended up with her donations to see if the foals ended up looking like her or Big Mac.
She’d sent in a … few gallons in the last week or so and so far she felt far better and not only that, it was a pretty good bit of side income! Too bad they banned her from further donations until they finish using what they have currently. It was understandable, to be fair.
She stretched and cracked her neck. It was time to get up for the day and -
She felt a rush of arousal suddenly. Far more than she had any reason to. It was like watching someone stripteasing right in front of her. She could feel arousal drip down her inner thighs and the weight between her legs grew. She was getting hard faster than she’d ever done before. It was insane.
Not only that, it was getting more and more intense. She could feel her body throb. She fell to the ground, one forehoof went between her legs while a soft downy wing wrapped around it and began stroking herself like mad. She didn’t know what was going on. All she knew was that she was more aroused than she’d ever been before. It reminded her of when she was inside of the Apple family. But her senses were dulled then. She remembered everything but her memories of how it felt were a little screwy.
It didn’t take long for her to scream aloud as she made a mess of her bed. She panted and moaned as each of the aftershocks went through her body.
She didn't know what caused it, she didn't know why it happened now. All she knew was that it felt amazing and Twilight probably had something to do with it or at least knew something.
Fluttershy was humming as she worked on her garden. It was a nice, simple chore that didn't involve any ponies. She didn't have to face anyone or risk seeing any of the Apples and remember how attractive they looked hanging from the rafters, slowly turning purple like ripening fruit.
No! That wasn't her! That was the bat! Dammit. It'd only been a couple of weeks. She still couldn't get those horrid thoughts out of her head. Worse yet they were more and more casually popping into her mind as if she was becoming numb to them.
"Fluttershy! Just the mare I was looking for!"
Fluttershy jumped for two reasons. One was the more universally understandable fact that she was surprised. The second was more only understood in Ponyville and to a lesser extent, Canterlot. That was the fact that Twilight was looking for her.
"Y-yes? Can I help you Twilight?" She asked, gulping in the hope it wasn't another experiment. She'd already bit her tongue and sat wrong more times than she could count since the last one. She didn't want any more changes.
"Well, I just wanted to see if there was anything going on! Any changes or anything? Just a follow up really." Twilight said casually as if she hadn't permanently inconvenienced her friend just for her curiosity.
Shy huffed a little but smiled. "No. There really hasn't been anything new or-" Oh no. She could feel it again.
"Oooh~ pupil dilation. They're even going back to suits. Interesting. What do you feel right now?" She asked as she circled around Fluttershy.
Shy was glad she was in the privacy of her own home as the arousal hit her full force. It was just like last night. Sudden, overwhelming arousal.
"Oh! An erection. With the speed it's growing at, you must be light headed. Excuse me." She said as she lifted Shy's tail without waiting for a reply. "Yup. Full body arousal. Fascinating."
Shy's mind was a blur. She wanted to do something. Anything. "If- if you're going to lift my tail at least take care of it." She managed to growl- yes, growl out.
"Increased aggression." Twilight added as her horn lit and a moment later Shy moaned as her mad scientist of a "friend" pushed a magically created strap on into her.
She felt her tongue fall from her mouth as she simply sat there, letting Twilight thrust into her. It wouldn't take long. She knew that much. It did take a tiny bit longer than the last time though as Fluttershy screamed and fertilized her garden with a different kind of seed.
Twilight hummed and got rid of the toy "If I may?" She formed it like a question but she didn't wait for an answer as she levitated Shy and fondled her package. "Fascinating. It seems like your body is slowly accepting your appendage!"
"You… you really like that word…" She grumbled, too tired to keep her thoughts to herself.
"It's a good word! Anyway!" With a little magic she summoned a clipboard and smiled.
Shy looked down between her legs as she was still hanging in the air and sure enough she could see a little bit of yellow starting to peek from the bottom of the balls - her balls, since it seemed she'd be stuck with them if her body was starting to accept it.
"So it seems that your body goes through a massive amount of pleasure when you impregnate someone. Even through a donation! That's really interesting. I'm going to have to look into a link between incubi and vamponies at some point."
"Wha- what?" Shy asked as she became more coherent. The dripping cock that'd been starting to retract throbbed at the thought of impregnation.
Twilight hummed and turned the clipboard around. On it was a long list. On top was "GA" with an "x" next to it and then "AJ" and "AB" with her new cutie mark next to it. Then below that was a long list of dates and there were two spots that had her cutie mark next to it.
"You see, I enchanted the seals of your donations so my list would be updated each time they were used and it seems you know pretty well when they are too!" She said excitedly.
Fluttershy sighed "You know trespassing is a crime right?" She offered weakly. She gulped as she looked at the list again. She really tried to ignore the top but it was staring her in the face. She would probably notice those two carrying more weight in a few months. She hated that the thought made her throb even harder.
"I'll check in after each update." Twilight continued, ignoring her crimes, not that anyone cared much about crimes anymore. After Luna came back Equestria went through such a drastic shift into the absolutely depraved and somehow, everyone, Fluttershy herself, mostly accepted it, even if they still complained and tried to press charges.
"Can you put me down now?" Fluttershy asked, a little embarrassed by the fact her shaft was still swaying as she floated in the air instead of retracting properly.
"Of course!" Thankfully, Twilight may have become one of the more depraved, due possibly to her proximity to the royal sisters but she was still Twilight to an extent. She gently set the Pegasi down. "Just take care of yourself and drink a lot of water. You never know when a donation will get used after all!"
Shy took a calming breath "of course. Thank you for the warning Twilight. That's so nice of you to worry. Even if you…you know… did cause this… after all." Shy wasn't usually snarky. But she could be when annoyed. Especially after the things she'd seen and gone through.
"What are friends for? I gonna go though! I'm running an experiment with Rarity! I want to find out if turning her into a dragon will give her enough greed to eviscerate Spike!"
"That's… horrible!"
"Isn't it though?! Science is amazing!"
Fluttershy watched as Twilight popped out of the area and sighed. What had the world become? And why was she only worried that Rarity would complain about it during their spa day instead of the fact she might kill Spike? He'd get brought back of course, but still!
She shook her head and got back to her garden, trying to ignore when her shaft swung against the leafy greens below.
It'd been a year. A full year of random erections. Spontaneous stiffies. Awkward arousal. Twilight of course had been fascinated by the changes.
Physically the shaft was completely pink with those once heavy blackish-red balls now a dark shade of leathery yellow.
The biggest change that had frustrated Fluttershy to no end was the fact that each time one of her donations was used it took longer to get off on her own. She almost lost her mind last time. Even thinking about Applejack and Apple Bloom in the last few months of their eleven month pregnancy with their heavy bellies barely pushed her past the edge she needed. Then they had their foals. Knowing that they had her foals was so erotic in it’s own right but it didn’t help her get off any more.0.
She could hear it in the back of her mind. The bat's instincts told her that she needed a pony next time. That she'd just end up sore, tired and painfully aroused if she didn't. She'd avoid ponies completely if she could but she had no clue when it would happen. One month there were none and the next it was every other day. It was completely without a rhythm outside of happening during business hours.
She sighed and shook her head. There was a very good reason to hide in her home and never come out again and honestly it sounded very ideal. But…if she was being honest over the last year she'd become more and more desensitized to her body and how the world had become.
She remembered the last public speech the princesses gave. Everyone was confused when only Luna was speaking until about halfway when Celestia got out from under the podium, face coated in what everyone by now knew was Luna's unique jet black seed.
When Luna stepped to the side and let her dress drop she didn't even try to hide the tent in it, nor how she then reached under the podium and between Celestia's legs.
The princess of the sun gasped and moaned through the entire speech before screaming Luna's name at the end.
It barely made a mention in the newspaper outside of how nice of a show of sisterly affection it was.
Fluttershy looked up and smiled a little as she saw her longtime friend. "Hello Rarity. I hope I'm not late. I was worried about my…issue."
Rarity had been changed by Twilight's experiments as well. Now sporting a mouth of teeth strong and sharp enough to gnaw through gems and some tasteful patches of white with purple scales with purple edges between her fur. There was also her horns which curled as gracefully as her mane. She often said that she enjoyed that she didn't have to worry about styling them at least.
She waved a good "Oh, pish-posh. Don't worry about a thing dear. We've all run into unexpected issues in the last few years. Applejack and her sister have foals, I'm, well, as you can see, Rainbow Dash seems to manage to get herself killed every other day somehow, pinkie is made of slime and I won't be so rude as to talk about your issue."
Shy nodded softly and nuzzled her friend "Thank you for understanding Rarity." Neither she nor AJ had mentioned about how the pregnancy happened. Most just assume it was her brother. Even though both AJ and Applebloom’s foals were light colored pegasi with light colored manes. AJ hadn’t approached her about it and it seemed that Big Mac had taken up the position of father.
"Any time darling. Now then. We have a spa date and we shan't be late."
Shy giggled "lead the way. Did they get that scale polish you requested?"
Rarity grinned."They did! I talked to Aloe yesterday." Rarity never hid her changes. She was horrified but confident. She found herself beautiful and maybe it was a coping method to start but now she seemed to have truly accepted it. Her confidence was partially what helped Fluttershy stop herself from holding herself up in her home all year.
The two ponies laid back in the water, simply relaxing and enjoying themselves. Nothing strange had happened. No one died, no one got fucked - though she did notice the spa sisters share a kiss or two here or there but they did their jobs so she wasn't going to say anything - it was just a normal, simple, relaxing visit.
"A spa date was exactly what I needed." Fluttershy mumbled
Rarity giggled "You say that every week dear. But I agree every week so I suppose I can't say much." She admitted.
Fluttershy hummed as she leaned over a little, surprising herself as she found Rarity's scaled shoulder right there. "Oh! I'm sorry! I must have moved. I'll just-"
"No, no! I moved." Rarity admitted as she got even closer and used a gentle bit of magic to lay Fluttershy's head against the well polished scales again. "We've known each other for quite some time and I've been thinking about this for over a year now." Rarity began
Fluttershy blushed a little and smiled bashfully, only for her eyes to suddenly narrow as she felt that annoyingly familiar feeling hit her. The voice in her head was stronger than ever. Her hooves and wings wouldn't be enough. They would never be enough again.
Rarity hasn't noticed yet as she continued, a light dusting of red on her face. "I- I suppose you may be confused. After all my talk of a prince and the like, I did some - a lot of thinking and-"
She could feel the blood in her body rapidly redirect. It knew what it wanted to do, she knew what it wanted to do. The only one who didn't was Rarity. Who was still talking about what sounded like a confession and this could NOT be at worse timing!
Correction. It could. But she really didn't want to think of those possibilities.
Still! She could feel it. It was like she'd just edged herself for hours. Instant blue balls. It hurt and ached. She knew what the only thing that would bring relief was and she hated how she could feel her self control fray.
The more of her pink shaft that rapidly spilled from her yellow sheath, the weaker her control was. She tried to control her breathing. To focus on anything else. But this room specifically had very little else to focus on.
So her eyes soon went back to Rarity. They hungrily ate her body and soon settled on her neck which was covered in her beautiful scales. As Fluttershy's shaft broke water her last somewhat innocent thought was that she was thankful that she probably wouldn't be able to bite through those.
"So…what I'm saying, through all of my rambling is…would you go out with me?" Rarity asked with a heavy exhale as she looked over at her friend who's now slit eyes had turned so thin they may as well be the side profile of paper.
She gulped and let her eyes move downwards. "D- darling?" She muttered before finally landing on the behemoth that once was between Big Mac's legs. Actually, she swore it was bigger than it had been when it was on Mac.
She gulped and sighed as she realized what was going to happen. She could use magic but she didn't want to hurt Fluttershy and she partially expected that Twilight would forcefully stop her from doing so out of curiosity anyway. "I swear. I'm going to bite Twilight's throat out." She grumbled before her crush jumped her, pinning her against the edge of the pool and knocking the air out of her as her fangs crashed hard against Ratity's scales and thankfully failed to penetrate them. A welcome outcome compared to the pain she felt between her hind legs.
"Fluttershy! Please stop! We can enjoy ourselves normally another time! Please! It hurts!" Rarity cried out as Fluttershy simply humped away, forcing more and more into her. "You're not yourself!"
She was right. Fluttershy had completely lost herself to her instincts. This probably wasn’t how Rarity had expected her confession to go as she felt tears fall from her eyes. She’d taken her fair share of large sizes. Partners and toys but they were always much more gentle. This hurt! Shy wasn’t taking a single bit of care for her. Treating her body like it belonged to her and Rarity… was getting a little turned on by that.
She didn’t know why! It wasn’t as if she wanted to go into a bar and tell the rudest, meanest patron to treat her like a piece of trash. But for some reason the idea of Fluttershy acting like an animal in heat, claiming her as brutally as possible as getting her just wet enough to allow it inside (water alone was a poor lubricator after all).
Rarity continued to cry and scream but soon moans and gasps started to make their way into the noises she was making. She could feel her insides being abused. She knew all too well from some of Twilight’s… other experiments, that this kind of abuse should probably kill her. It seemed that her insides had been strengthened by her changes. It probably shouldn’t surprise her that with how aggressive dragons were that they apparently fucked so brutally that their insides needed to be stronger than normal.
Shy continued to knaw at Rarity’s neck, trying to pierce through her scales as she raped her friend. Even though her body felt like it was right on the edge of cumming, she wasn’t getting there fast. No, she was thoroughly going to fuck Rarity. She was long gone as she felt Rarity’s tight marehood around her cock. Growling like a true animal.
“Ah, Nn~ Mm~” Rarity had fully moved past her screams. Even though she still had tear tracks on her face, she’d fully accepted this new discovery about herself. It hurt so badly. But it felt so good at the same time. It felt so good to be treated so badly by Fluttershy.
Rarity’s eyes widened as she felt her scales break. “Yes, Darling! YES~!” Fluttershy’s fangs stabbed into her neck. Luckily, thanks to the thickness of her scales, her fangs didn’t get as deep as they could have. But more importantly from the blood flowing from her neck was the seed flowing into her womb, everywhere else and then into the pool. She could just imagine that massive pink shaft throbbing as it pumped load after load into her body. She wondered if she could convince Fluttershy to abuse her throat next time so she could watch it throb properly?
It felt like it took ages and Rarity’s belly looked like AJ’s did a couple months ago. She panted and looked back at Fluttershy. The mare’s eyes were a little better but her breathing was still ragged and heavy. “F-Fluttershy?”
The next thing Rarity knew she was forced under the water. Her eyes went wide as Fluttershy sat down on her face. An unspoken order for the fashionista to eat her out if she didn’t want to suffocate.
Rarity obviously didn’t want to suffocate and she also felt like she’d enjoy the taste of what was on offer, even if it was going to have a lot of mineral water and cum mixed.
With that in mind, Rarity got to work. Quickly sticking her tongue out and getting a mouthful of water in return. This was going to be rough. She glanced up through the cloudy water and around the massive cock that was bobbing above at Fluttershy’s face. She looked so vicious. So unlike Fluttershy but that in itself was so arousing. It only spurred Rarity to work harder to get the mare off.
Fluttershy for her part simply ground her pussy harder into Rarity’s face as the mare struggled for both air and to pleasure the mare above her both physically and sexually.
Fluttershy watched with an elation she couldn’t understand as Rarity struggled and her face started to change color which got Fluttershy off even more. It was that innate desire for fruit. Though the fact she wasn't fang deep in her neck showed that at some point the priorities had changed a little. Fluttershy could still feel that desire to feed but pleasure had overpowered it.
Rarity was both terrified and more turned on than she'd ever been. She was drowning. Actually drowning while eating pussy. She be happy to go out this way, if only because she knew that Twilight could bring her back. She wouldn't want this written on her tombstone of course!
She could feel Fluttershy's grinding intensify as the edges of her sight went dark and in the next moment her hind legs clamped painfully against the sides of her head and while she couldn't hear it, Rarity was sure her friend turned attacker was screaming in pleasure.
She lost more and more of her sight as her thoughts became hazy. This might be it. She didn't even notice the legs pulling away from her head or her body being moved until she was suddenly able to breath again.
She would never admit just how much water she ended up throwing up a moment later. A part of her wondered how much was actually water and how much was from Fluttershy herself.
"Oh my goodness! I'm so sorry!" Fluttershy, having finally come back to her senses whimpered, tears falling from her face as she tried to ignore the still half hard shaft. "I- I just- I couldn't- a- and then- and you-"
Rarity rolled into her back and smiled as are gently set a hoof against Shy's lips "Shh. Darling, if anything I must thank you."
"What?"
"You see, you've - how do I put this - awakened something in me." Rarity admitted. "I don't know how much you may remember from earlier but before you oh so, brutally raped me and nearly drowned me - " Rarity shivered with a little moan " - I was confessing my feelings for you. If you'd still have me I'd love to give you an outlet for your aggressive side. If you and the Flutterbat side are truly one now then it's only right."
"Oh. That's uhm, that's very nice of you Rarity. I would love to if you'd be willing after you… look down."
Rarity raised a brow and did just that "Well, it is quite nice but I don't see what-" pulling her eyes away from the growing cock under Fluttershy, Rarity noticed something pink on her lower abdomen. Two butterflies and a bat. "Ah." She sighed and giggled. "You know what? This is fine. I'm fine with this."
"R- really?" Fluttershy asked, sounding surprised, cock visibly throbbing again.
Rarity smirked and gently rubbed the pregnancy mark. "Mmm~ yes. I'd be quite happy to carry your foals. I'd be even happier to date you of course."
"O-oh! Yes! Yes of course!"
"What are your findings?" Luna asked as she held her sister's head down. She'd long since changed color and lost consciousness. It was just a matter of time now.
"It was surprising! The gaining of a phallus was unexpected but the desires were just like what you explained. Blood, breeding a love of fruit and even your suffocation kink!"
Luna chuckled and moaned as she moved Tia's unconscious head a bit more "Mmm~ how my genetics ended up passed through bat's of all things, I'll never know but I do find it hilarious that your shy little friend is the one who ended up as one of my family." She said with another moan as she came, groaning as she slammed Tia's snout against her crotch again and again.
A moment later, Celestia disappeared into whisps of sunlight and the last few ropes of Luna's orgasm ended up flying into Twilight's face. Luna scowled and shrugged "Sister always died too easily. I'll do some of her paperwork to make up for it." She grumbled as she stood and looked back at Twilight who'd already licked her face clean. "What is your next experiment?"
"Well I was thinking about adjusting Pinkie's instincts as a slime. Hopefully she'll absorb one of the cakes and I can see how well it works!"
"You're a twisted mare after my own heart."
Author's Note
This was kinda messy and was more focused on the fetish than the action.
But I'm done with it so, eh.
