The Flutterbat

“D-doing what?” Shining blinked, then his gaze fell on the condoms on the floor. “Whoa uh… and she’s okay with that?”

“Of course I am,” said Twilight dreamily. “I asked for it. I think? Mmmm…” Her eyes drifted down to her brother’s dick. It was above average, though not as massive as Fluttershy’s. Still, it was her brother’s cock, and that added prime kink factor.

Shining gulped when he saw his sisters line-of-sight and took a step back. He had probably not hidden it because he didn’t expect her to look down. Fluttershy licked at her neck once more, slipping her nightie over Twilight’s head, quickly dropping her bra and panties all the way to the floor to leave her nude.

She whispered in Twilight’s ear, “Fuck him, hard.”

“Mmm, that’s a good idea,” Twilight panted. “Glad I thought of it.”

“W-what’s a good id-” Shining started.

Twilight turned and pushed into Shining’s room suddenly, laying a deep kiss on his mouth. His eyes widened, taken off-guard at his nude sister kissing him. She pushed her equally nude brother back onto the bed.

“Mmm, no chromo,” Twilight purred as she climbed atop him.

Fluttershy strutted in, not needing to turn the light on to see what was going on. Cadance was sitting on the bed next to where Shining landed, but didn’t seem upset. In fact, she giggled when Twilight jumped him. Probably not having caught the previous conversation, she pulled a condom off the strip with clear intent to give it to him for fucking his sister.

“Aw, you’re such an accommodating fiancée,” giggled Fluttershy as she shucked off her own nightie, leaving that and her underwear in a trail as she walked to the bed.

“D-did you put her up to this?” Shining asked Cadance. “After I told you about my fantasy?”

“Nope,” Cadance giggled. “Looks like she had the same one. Go on and do her, we’ll say siblings don’t count as cheating.”

“Do I count?” Fluttershy purred, nabbing the condom away just as Shining was going to grab it. She said to Shining. “Would you do me a favor and fuck her in the ass first? I want to give my sperm a good head start before anyone else expels a load in her baby maker.”

“Wait, she let you cream in her bareback?” Cadance blinked, then smirked. “Well, you’re not at my school anymore, Twilight, so you won’t get a lecture on how bad of an idea that was. Honestly, I feel like a hypocrite every time I get onto someone for anything sexy.” She glanced in Shining’s direction, good fiancée that she was, and asked. “But even up the rear, you really should…”

Cadance trailed off as Fluttershy flicked the light switch on. Fluttershy didn’t realize for a few moments that she’d done it with her tail, or that she even had a long demoic tail now. Cadance didn’t notice either, her eyes frozen on Fluttershy’s shaft, watching it throb, slick with pussy juice. Her mouth fell open, literally drooling at what she saw.

“It’s massive!” Cadance gasped, reaching out to run her fingers over it, tugging as if to verify that it was real. “How did you ever hide this monster? How do you get hard without passing out from blood loss? Oh um… it’s okay to fondle right? What was your name again? I don’t think Twilight introduced us.”

“It’s very okay,” purred Fluttershy, petting Cadance’s face. “Names aren’t important, and I think he wants more than fondled.”

“Well, stranger-sex is kinky,” winked Cadance; Fluttershy figured she had a naughty side, but she still turned to Shining to ask permission. “It okay if I get pounded by the trap?” She added as she looked back at Fluttershy with a blush. “No offense.”

“Mm, none taken,” Fluttershy said. Cadance had no idea what a trap it really was. It occurred to Fluttershy that if she proceeded, she’d technically be a serial killer at that point, but it wasn’t like she wasn’t doing them all a favor at the same time.

“I can’t really say no when I’m about to bang my sister next to you,” Shining moaned, not taking his eyes off Twilight to realize how massive his potential competition was.

Twilight’s eagerness was more than just following Fluttershy’s suggestion. She could tell Twilight had wanted to smack bellies with her brother for quite some time. As he panted and massaged her breasts, she pushed herself down onto him, trying to impale her rear entry as soon as she could. She grunted in frustration, then belated realized it was a lubrication issue.

Not feeling like going to get any, instead Twilight pushed him into her well-used slit to get him nice and slick. He groaned at suddenly feeling the inside of his sisters most intimate area, rubbing her body up and down. She dug her nails into his chest as she pulled all the way off after a few strokes, then guided his shaft to her hind entry again with one hand and sat back on it.

Shining seemed stunned at how effortlessly she took him into her virgin ass, shoving herself downward with inhuman strength until her cheeks smacked against his balls. She gripped his thighs around him, drooling on his chest as she began rolling her hips, impaling herself on her sibling’s cock with fervor. Shining rolled his eyes back at the tightness, rubbing his hands up to her breasts and squeezing.

“Are those electronic cosplay ears? They’re moving.” Cadance asked Fluttershy, getting on all fours on the bed, facing away from her. Fluttershy pushed her forward so that their penetration would be right beside Shining’s face, but took a while to realize what she meant.

“Something like that,” Fluttershy said, feeling the bat ears that had sprang upon her head.

“This is gonna stretch me so much better than Shining’s,” Cadance purred as she reached between her legs to grasp Flutterhy’s shaft in her agile fingers, licking her lips. She then realized what she said and checked to see if Shining heard.

“Can’t believe I’m finally fucking my little sis,” Shining panted, quite distracted as he gripped her hips and pounded his hips upwards. “Your asshole is amazing Twilly, I’d have came already if I hadn’t already gotten off twice tonight.”

“I should have let you inside me years ago,” said Twilight, salivating all over her own breasts as Shining watched them bounce hypnotically. She leaned forward to kiss him, almost choking him with her slowly lengthening tongue. She added between slurping kisses. “Let’s fuck Mommy and Daddy tonight too.”

“I don’t think they’d be up for it,” chuckled Shining. “I’d be all over it if they were though.” Fluttershy was sure they’d get to them later.

Fluttershy was about to plunge into Cadance when she realized the silly girl had opened the condom packet and was putting one on her.

“Oh no you don’t,” Fluttershy moved down against her, grasping her breasts in both hands and going for her neck.

Cadance arched her back at the sudden bite, shivering at the realization of how cold Fluttershy’s main body was compared to her shaft, but didn’t try to buck her off. Fluttershy enjoyed the lady’s taste, but at the same time thought it was a shame that she’d gotten to her 20s without having been made pregnant even once, and the same for Shining at not having made anyone pregnant. Now Shining had lost his chance and his fiancée was Fluttershy’s to knock up.

Fluttershy pushed Cadance’s hand off her shaft with one hand as the other squeezed her breast again, sliding a fingernail along her own length to slice the rubber off her cock. With her back arched due to the biting, Cadance didn’t realize that it’d been torn off until Fluttershy sank her dick into Cadance’s love oven. Fluttershy shivered in delight as easily the most experienced pussy she’d had so far slid over her shaft and convulsed in a deluge of milking motions.

Cadance squealed in delight, but it was a good dozen strokes in before Cadance put together that it felt so good because it was bare. She was feeling the curves of a proper dick inside her for the first time.

“I’ve never been so full… wait… y-you took it off,” Cadance panted as if Fluttershy might not have realized.

“Of course I did,” purred Fluttershy, getting better still at talking with her mouth full. “At your request; you wanted to cuckold your small-dicked fiancée.”

“I-I did?” Cadance panted, but despite her reluctance rolled her hips back against Fluttershy. Fluttershy’s balls swung and slapped Cadance’s bare belly with each long stroke of her hips, plowing into another fertile field and feeling no less able to fertilize it even after several orgasms.

“Mm-hm,” Fluttershy assured. “Remember? You told me you wanted impregnated by a more worthy cock in front of him.”

“O-of course,” Cadance drooled on the bed and gripped the sheets as Fluttershy squeezed and twisted at her larger breasts.

Shining still hadn’t noticed, smacking lips with Twilight as he jackhammered his hips up against her, her pussy drooling a puddle of Fluttershy’s cum on his belly as he did. Twilight though was more perceptive, reaching one hand over to grasp at Cadance’s breast, likely wanting to feel another heart stop.

“That’s right,” purred Fluttershy to Cadance. “Now raise one leg to make sure he can watch me fill the hole he’s never felt bareback.”

Fluttershy pulled Cadance’s right leg forward and pulled it up as far as the flexible lady could to make sure Shining could see. Shining hadn’t heard their conversation, but he noticed when Cadance’s cunt honey splattered on his face, slung by Fluttershy’s meaty ball sack and splashing from the impact of wet flesh. He looked over to find his fiancée’s cunt milking a bare dick that wasn’t his own, getting a good look at the shaft for the first time.

“Fuck that’s big,” even Shining had to note, but added. “Uh guys? Condom?”

“Mmm, we’re not using one,” Fluttershy told him. “I was going to, but Cadance insisted otherwise, didn’t you, sweet should-be-a-milf-by-now?”

“Oh yes,” Cadance drooled against her pillow as she clenched two handfuls of blanket. “Watch my womb painted white inside by a girl I don’t know...”

“That’s right,” purred Fluttershy as Cadance fit what she’d been told into her own narrative. “I knocked up your sister, now I’m going to knock up your fiancée too. You’re going to watch, and you’re going to love it.”

“Yes,” Cadance drooled. “You’ve never felt my bare cunt with your tiny dick, I refused to ditch the condom with you, but now I have one that’s worth my time. Does that turn you on, you cuckold?”

“F-fuck yes,” Shining groaned, staring at her vulva as they stretched wide, flicking over every curve and veing of Fluttershy’s shaft. “I don’t even know why… fuck…”

Fluttershy wondered if Shining was just drunk from her influence too, or if figuring out people’s kinks was a vampire power. Then again, maybe it wasn’t hard to assume a guy that dates a hot and easy woman was into it.

Shining was definitely into it, because seconds later he was blowing his load into Twilight’s rear. He grasped her chest as he did, slurping at one of her nipples, but never taking his eyes off Cadance’s overstretched pussy.

“Love you Twilly,” he grunted. “Oh, gonna fuck you every day from now on if I can.”

“I love you too, brother,” purred Twilight, grasping one of his hands in her hand that wasn’t feeling up Cadance. “But you’re still a shitty lay compared to Fluttershy. Come on, feel this superior specimen.” She moved his hand to Fluttershy’s balls, and he massaged at the sack.

“Did you think you’d be the first to have me bareback?” Cadance gagged a bit, overcome with dizziness and not realizing she was on the cusp of death. “But Fluttershy… twice the man… you… oooh.”

“Hear that, brother?” Twilight said as she continued to rock her hips against her brother’s spent dick. “Someone with tits is more of a man that you are; how pathetic.”

“Yeah, cum inside her,” Shining shivered and felt the bulge in her belly as the shape of Fluttershy’s rod moved in and out. “Every time I look at someone else’s kid I’m raising, I’ll remember how inadequate I am.”

As Twilight and Shining spoke, Cadance was shaking violently, convulsing and gagging for a few long seconds. Twilight moaned as she felt Cadance’s heart stop, grinning widely as her body shivered and reanimated.

“Mm, so fascinating,” said Twilight. “I’ll definitely be writing some research papers on this.”

Fluttershy blew her load while Cadance lay still, then Cadance awoke to the burst of fertile juice into her womb. There was no less than there was for Rarity and Twilight, Fluttershy never seeming to run out,

“Gods, you cum like five times more than me,” Shining had joined in cucking himself at this point.

“Hold him, girls,” said Fluttershy as she extracted herself, letting Shining see her moist shaft as she did. “Take him up the pussy now if you’d like, Twilight. Even the worst lay deserves his sister’s bare pussy… which reminds me, I’ll need to hunt down Zephyr later, maybe with Dashie to give him a special treat.”

“Oh fuck yes, Twilly, I’ve wanted your pussy for so long,” Shining panted. “This is all so wrong! I love it!”

Twilight pulled him into a sitting position, sliding off his meat in one hole and seamlessly pushing in on the other, panted as she did so. She shivered, clearly liking his equipment even if currently unable to admit it for cuckolding purposes. Shining showed no resistance as the other two femmes gathered around, though he shivered a little when Fluttershy leaned in.

“Let’s drain him together,” cooed Fluttershy. She tugged him up to her knees, pushing her cock tip against his posterior as well, lubricated by his fiancée’s juices.

“Uh, I’m not bi,” chuckled Shining nervously.

“Well, technically she’s not a guy, so…” giggled Twilight.

“You’ll be everything when I’m done with you,” purred Fluttershy. “Besides, what’s a better way to cuck you than to fuck you up the asshole with your girlfriend’s pussy juice as lube?”

Fluttershy sank her teeth in first, giving her fangs a moment to release the pleasurable hormones into him before ramming with her hips. He started to protest again, but what he assumed would hurt felt like pure heaven as he felt his own bottom stretched out. He shivered and squealed, his hips rocking back and forth to push into his sister and then Fluttershy to push into him.

Twilight bit down on the other side of his neck, the nerd not needing the instinct to know exactly where proper the artery was. Cadance still hadn’t been told she was a vampire, only knowing that she felt the need to follow Fluttershy’s commands, but quickly caught on. She couldn’t get in good on his neck, so took the wrist of the hand that had been groping Twilight and bit there.

Soon the sound of their collective slurping competed with the slapping of bodies as Twilight and Fluttershy played pelvis ping-pong with his hips. Shining realized something was up, but didn’t care. Whatever it was, it involved him plowing his sister in every hole and he was fine with that.

“We’re not going to sparkle, right?” Cadance asked, still slurping, but slightly concerned as she put two and two together.

“We won’t,” Fluttershy grinned. “Not unless you count glistening with sweat, we’ll be doing a lot of fucking… don’t ask why we sweat in our condition. I have no idea how this works, to be honest.”

“Thank goodness,” Twilight said, happy she was going to get to figure it out herself.

Even though he was drained faster, Shining still shuddered with orgasmic bliss as he passed over. It made Fluttershy wonder if it was actually the dying via a vampire bat that got them off rather than the sex. She’d have to test that out sometime, but tonight she wasn’t leaving any guest unfucked.

Fluttershy took a bit longer, so Twilight and Cadance continued to hold him as Fluttershy dug her fingernails into his behind. She noticed that even her nails were slowly reshaping into claws as she pounded his ass.

“Will his dick grow?” Cadance asked hopefully.

“Probably,” smirked Fluttershy. “Maybe not as big as mine, but it certainly can’t get smaller.”

Fluttershy was glad she was delayed in her own orgasm this time, because it getting drained by a vampire and two thralls at once had another effect in that it sped up the transformation of all involved. For Twilight and Cadance, it meant the lengthening of tails and some small ear growth, as well as a bit of a nub that would probably become a cock eventually.

With Shining, Fluttershy felt something more. She could feel his insides churning as she pounded her ass, and felt her balls slap against a wet hole as a pussy formed behind his balls, much like Fluttershy had even if no one had noticed.

Fluttershy grinned. Knocking him up with the same cock that cucked him seemed very appropriate, so she withdrew from his ass with a lewd slurp and rammed his newly forming female bits before they was even done forming. She felt her shaft push apart his insides deeper as it lengthened and began to form his womb.

Shining squealed more as he suddenly found out he had a pussy now in the best way possible, by getting it impregnated seconds later. Fluttershy groaned, expelling another hot load into his new nethers, shaking violently as she did so. She felt nubs on her back twitch, realizing that wings were now forming there as well.

“That’s it, take my seed, bitch,” Fluttershy groaned, finally feeling like she’d fully ‘fit’ into her new role. “Cadance, maybe you should give him some bare pussy for being such a good boy; just remember who owns both your bits. Me and Twilight are going to finish off the other girls, then we can all go to their parents’ room together.”

“Sounds like a plan,” Cadance purred, pulling the confused Shining out from between them, separating from both with a pair of wet squelches.

“Oh, and explain it to him,” Fluttershy instructed, grabbing Twilight by the hand and jumping off the bed. Her tail swished behind her as she led Twilight out of the room.

“Bye big bro, fuck ya later,” Twilight smiled and waved.

“Explain?” Cadance seemed unsure. “I don’t actually know-”

Fluttershy closed the door, leaving her to wing it. It wasn’t like Fluttershy understood much more.
