Twilight merges Fluttershy and Flutterbat. But Shy has no control as she conducts a macabre experiment. (Death, amputation, blood, futa, rape, dark shit.)

Twilight loves experiments. No one else used to mind all that much. But things all across Equestria changed once Luna returned. Things got... strange. Mostly lewd. No one knew why but the entire kingdom changed.

Twilight included.

Unfortunately, her experiments weren't as lewd in nature. They were cruel.

As such, when Fluttershy visited her at the Apple Family farm one night and was suddenly hit with a spell and heard the word "experiment" she knew it couldn't be anything good.

A side to the Flutterbat returns story. Doesn't really begin or end well. Pretty much just dark porn.

Blood drinking, rape, amputation, death of an old mare, futa. Impregnation. Dark Bs. It's whatev. In this AU of Equestria after Luna's return, the CMC aren't children. Because she wasn't in the pic that inspired this either.

Fluttershy REALLY Hates Her Experiments

Fluttershy didn’t know what spell Twilight cast on her. All she knew is that her mind was extremely foggy. “What- What did you do?” She panted out, glazed eyes looking at her more than slightly mad friend.

Twilight waved a hoof and smiled “Just a little thing. We need everyone for this experiment and, honestly, you're not the one I need for it. It’s the other you.” Twilight explained, causing Fluttershy to flinch.

She was confused for a moment as Twilight said that. The other her? Who could she mean? But then her mind, for a quick moment thought of how badly she wanted a nice juicy apple and it clicked. “The- The bat? You want- why?! Why would you do this?!”

Twilight giggled “Because I need the information, you silly filly. I wanted to do an experiment involving Flutterbat but I needed you to do it. Honestly though, I’d rather keep that side of you around so I’m hoping that it’ll become semi-permanent.

Fluttershy was horrified - she wasn’t that surprised anymore. But, horrified. The fact that Twilight wanted her to - to merge with the bat side was… well it wasn’t something she wanted to do whatsoever! She wanted to just leave but her body wasn’t listening to her. She felt Twilight’s magic pushing her forward.

“Alright! I have everything ready for you inside! The Apple family were kind enough to join us for this experiment.” She explained but Fluttershy had the distinct feeling that they were asked as clearly as Fluttershy herself was. That is to say, they weren’t.

Her suspicions were clarified when she was pushed into the room and saw the Apple family. That feeling only lasted a moment until she was hit with a wave of stranger feelings.First and foremost was horror and disgust.

On the couch was Big Mac. Seemingly asleep but she doubted it was anything so light as sleep. He was completely naked and drooling a little. There was nothing too bad about that in itself but that’s where it ended. To the side the rest of the family were hanging from the rafters. Granny’s eyes had already rolled back, and she wasn’t breathing. She was dead. Next to her was AJ and Apple Bloom. Their limbs were gone. Left as bloody stumps. The fact they weren’t bleeding more was probably due to Twilight. AJ was still. Alive but breathing shallowly while Apple Bloom was still struggling. Eyes wide. They both had tears falling from their eyes and their tongues hanging out.

It was a horrific scene, yet Fluttershy couldn’t stop the thoughts from popping into her head about how the way they slowly changed color made them look like ripening fruits. So tender and ripe for draining. She was pulled from the scene as Twilight spoke up again.

“The experiment is to see how Flutterbat reacts to the Apple family looking like, well, Apples! I want to see if she’ll try to drain them. Big Mac already looks the most like an Apple so he’s the control. He’s tranquilized heavily so he’ll sleep through the whole thing. So, we’ll start with him.”

“Th- this is… h-horrrrib…” she tried to speak but words were becoming difficult. She was drooling. Salivating over the amputated torsos of her friends! She really was a monster.

Twilight didn’t listen as she pushed Fluttershy towards Big Mac and smiled as the pegasi reached out on her own. Her eyes had narrowed, turned to slits and her words had stopped. Shy had lost to the bat.

Fluttershy was still there though. Inside, watching as she lost control of her body. She watched as she climbed on top of Big Mac and ground herself against him. She could feel his shaft grow against her underside. He was big. The entire town knew it. It was why his name was so fitting. Though she dearly hoped his parents hadn’t named him because of his dick size.

She could hear scribbling, but she couldn’t move her head to see it. It was probably Twilight taking notes. She was getting really angry right now. But then she felt Mac’s flare press against her pussy. It was thick. Wonderfully so. With a growl her body lowered. She felt so full! More than any of her toys! Way more than that one time she got caught by the pack of timberwolves!

She bounced her hips, taking more and more of him in. She could feel her insides stretching to accept it all. There was some pain, but it was as if her body simply turned it down after a couple moments. She could feel the intensity lower. She wasn’t sure if that was her or Twilight’s doing.

Soon she was hilted. She could feel her belly pushed out by its size. It was as massive inside of her as it felt. But she could still feel that she needed more. Something that a dick couldn’t give. Then her head shot down at Mac’s neck, fangs catching a vein with ease as she pumped her hips. She tasted the coppery liquid move down her throat and she hated the fact that her mind had decided it was delicious instead of disgusting. She wanted more even as she wanted it to stop.

The blood flowing down her throat made her body burn in the most delightful way. It was like what she imagined draining a zap apple of its juice would be like. Her entire body felt like it was on fire. Her hips moved faster, and she wrapped her forehooves around his neck and pushed her teeth deeper. She wanted more!

She moved her hips more. Starting to add some angles into her movements as she continued to drink down more and more of the delicious red liquid. She was in bliss and while she did still hate it, it was hard to focus on that hate when she could still feel everything.

Soon, she felt it. Both his blood flow started to slow down, and it cock started to throb harder than before. She knew what was coming and let out a guttural scream as she pulled from his neck as her insides were painted white. She’d drained him in two different ways. She moaned as she felt each throb accompanied with another little bit of weight inside of her. It was so warm inside of her. The opposite of course, was Mac, who was cold and what bit of blood had kept him hard was starting to flow into the rest of his body.

She pulled off but it felt… odd. Her body didn’t bother looking. It probably knew what was going on, purely by instinct already. But she could feel her crotch was heavier and in the split-second glimpse of Big Mac she got before her body turned away, she was confused that she couldn’t see any of his package. Not even his flagging shaft was left. He didn’t get soft that quickly, did he?

Then she realized where her body was going next. She really wished she had control as it went directly for Granny, whose body was closest. But then it stopped. For a moment she thought it had listened to her before it suddenly leaped up and dug its fangs into the corpse's neck. But nothing happened. Without any blood flow, no blood was coming towards her. Her body bit harder and harder, eventually biting out a chunk of granny’s neck itself where it was finally able to get some blood. But there wasn’t enough. It seemed to quickly lose interest in the rotten fruit and eyed the two still living fruits. AJ had turned more purple since they’d started, and her body jumped up.

AJ’s blood was a little different. It was like it had a kick to it. It was just as delicious though! But there was something else going on. She could feel something strange on her crotch. A throbbing weight that was grinding against AJ’s pussy. Her body pulled back from feeding for a moment just to look down, which showed Shy where Mac’s package had gone. Jutting from her crotch was a massive red shaft and she imagined his heavy dark red, leathery balls were just below.

Her body used that moment to aim before it let out a moan that was mirrored by Shy inside. She could feel as the cock pushed into her friend. Forcing itself deeper and deeper with ease. As if it’d been made for Mac. Or at least molded for it. Why was all this happening? Why couldn’t they just use actual fruit for experiments?! Why did she grow a dick?! Why was that dick stolen from Big Mac?! Why did it all feel so good?!

She bit back down on AJ’s neck as she wrapped her limbs and wings around her, and her hips started to move. She could feel a small bit of resistance. Maybe a depth that Mac never wanted to push due to hurting her. But the bat didn’t care about such things and simply slammed at the barrier. Again, and again until it slowly started to allow entry. She could hear AJ’s wheezing cries and whimpers right next to her. They were so weak though. But she felt so good around her cock that it was hard to focus on caring. She thrust as hard as she could, battering away at her insides as she felt the warm blood fill her mouth. It was absolutely euphoric.

Then AJ’s movements stopped completely. She stopped making noises. The blood flow slowed down. She heard scratching from the side “Applejack died at…” She tuned out the rest. AJ had died while she was doing this, and she was still going! Her body wasn’t letting up. AJ was still warm, there was still delicious blood and a warm hole. She could feel those were all that mattered.

Thrusting away at a corpse did take away from the pleasure she was feeling earlier. She was horrified at how little it took away though. If she’d been at home, in private she’d have a hoof between her hind legs going at it like mad. Maybe even if she wasn’t in private!

She kept moving, thrusting her hips and fucking the dead body of her friend and she wished she found that more disgusting than she did.

Another guttural noise as she came and flooded AJ’s insides with seed. It was different than before. Her orgasm while riding Mac was really good but this one was… strangely better. Not in the stupid idea that a male orgasm was better. She doubted that by far. But there was something else. Some other things about it that made it feel amazing. It wasn’t pure pleasure from her cock, nor was it the pleasure from her pussy as she came from there too. It was just full body pleasure caused by something else. But she didn’t focus on that for very long.

The bat didn’t allow a single rope to stay outside. She noticed a small glow come from AJ’s body and then her body pulled back and pulled out. Her cock flopping out and swinging from between her legs as cum dripped from AJ’s body but… she was breathing now! Very weakly but still! Then there was something else. She saw her cutie mark on AJ’s belly. No. Wait. Not hers. The bats. But… it wasn’t that either. There were two butterflies and a bat. It was like Twilight had wanted. Her sides had mixed. She had impregnated her friend.

But her body didn’t linger on that as her cock throbbed and grew again as it put its eyes on Apple Bloom. The youngest (But still legal) Apple was still struggling. She still had air somehow and hadn’t changed that much. But the way she hung and the way she was changing was still hitting that instinctual desire to drain fruits… and breed.

She hadn’t realized it before, but that desire was strong. Very strong. She wanted to put foals into Apple Bloom. As her body jumped forward at the mare and since she was already hard, she simply shoved herself inside the incredibly tight hole. AJ had been perfectly molded for Mac’s cock. Apple Bloom though? She was tight. Clearly, she wasn’t as active as her elder sister. But her body didn’t care as he thrust like mad. Forcing harder, which caused Apple Bloom to struggle even harder. She could feel herself stretching the mare out.

Then she finally bit down. Apple Bloom’s blood was the smoothest of them all, with a tiny bite to the end of each gulp. A small part of her wondered if everyone’s blood was so uniquely delicious. She was sure she’d have to push away all these thoughts afterwards or she’d feel horrible.

But, in the moment she felt too much pleasure to care. The deliciousness of the blood, the tightness of Apple Bloom and how smoothly it moved thanks to how much cum her cock was coated in. It was all just so good. Just like her sister, Bloom’s body was soon wrapped up by Shy’s body’s wings and limbs as her thrusts got faster and went deeper. Shy could feel the bulge on Bloom’s body pressing against her wings. She was the smallest of the Apples outside of granny. Which was fair since the rest of them were pretty large. It didn’t matter though. She continued to thrust just as hard. Her body wanted to bury every inch of Mac’s dick inside his other sister too. So that’s exactly what she did. With a lewd slap she felt the last bit of her cock push inside and Bloom’s pussy clench tighter around it. Bloom was cumming.

She cooed and growled as she pumped her hips in long, brutally hard thrusts. Hopefully Bloom wouldn’t die for a moment like AJ had. At the least that had shown that Twilight was willing to bring them all back if it happened.

Shy was a little surprised when her head pulled back and aghast as it licked up Bloom’s tears. The bat side was just sadistic.

More thrusting, more blood. Delicious, pleasurable and horrible in equal measures but she couldn’t help herself in a literal, physical sense and… even if she was suddenly able to control herself, she wasn’t sure if she’d be able to stop at all.

She moaned as her belly felt so full of blood. It was delicious. Just as good as fruit juice. In her mind though, they were one and the same. Interchangeable honestly.

She heard Bloom’s breathing start to get more and more uneven. She was probably starting to lose her mind. Pain, pleasure, a lack of oxygen and losing blood. All of that together, it was understandable. Shy’s own mind had become a muddled mess of itself. The fact she wasn’t absolutely horrified at what she was doing and seeing was proof enough of that.

She could feel it again. That building pressure. Her flare swelling as her balls pulled up towards her body. She knew what was going to happen and the moment it started she felt that same full body pleasure from earlier. It was hard to explain it more than that. It was just pure pleasure.

She felt it as she flooded yet another Apple with seed and she came as well. She felt the smallest young adult Apple’s belly start to bulge out under her wings and legs. Just knowing how much cum she was forcing into her was something else. Either Big Mac had enough cum to impregnate the entire town, or something about her body had caused it. She didn’t know and Shy doubted either side of her really cared at the moment.

Her body pulled away, blood dripping from her lips as she saw the mark on Apple Bloom’s belly too. But her cock still throbbed. Her instincts still needed more. They demanded more. Her body turned back towards granny and Fluttershy’s metaphorical stomach dropped. She really, really hated Twilight’s experiments.
