The night had come quickly for Twilight and her friends as she, Pinkie, Applejack and Rainbow Dash all made it to Rarity's boutique.
"I can't wait for this slumber party girls!" Pinkie chirped excitedly as she opened the front door. As the four girls walked in, Fluttershy looked up from her seat on an ottoman by a rack of dresses.
"You girls made it!" Fluttershy happily said as she struggled to get up. With one hand on her belly and the other being used to lift herself from her seat, she slowly stood up and trotted over to try and hug Twilight, who had to lean forward to hug otherwise their bellies would keep them apart. "Sorry, it's just so cumbersome with my baby belly."
"No problem, Fluttershy. We're all in the same boat, remember?" Twilight reminded her. True to her word, the girls were all indeed heavily pregnant. Such a coincidence that all their boyfriends got them teen pregnant all around the same week.
"I wish I wasn't. The soccer team has been sloppy since I got knocked up!" Dash complained, patting her stomach.
"I don't mind it at all! It feels super duper great!" Pinkie, who was wearing a graphic tee that read "Future Party Animal on board", disagreed.
"By the way, Fluttershy, has mah big brother been keep in' his promise since he knocked y'all up?" Applejack asked.
"Of course. He checks up in me everyday after school, sometimes even spending the night if my parents aren't home." Fluttershy said, looking lovingly down at her belly. "The twins are going to have a wonderful father..."
"Did I hear that everybody's hear?" Rarity's voice rang from the back room.
"Oh yeah! Coming Rarity!" Twilight called as she and the girls walked towards the back room. The girls were surprised to see the entire back area of the shop redecorated to fit the needs for a slumber party. The storage racks were moved out of the way of a carpeted area Rarity had set up with enough inflatable mattresses for all of them, a snack table and cooler, and a lounger which Rarity, dressed in a long teal nightgown, was already taking place while she soaked her feet in a bath of warm water.
"Nice set up, Rare." Applejack complimented.
"Oh, it's nothing. Just a little something Thunderlane set up for his beauty queen." Rarity blushed, batting her eyelashes for effect.
"Less talking, more SLUMBER PARTAYING!" Pinkie shouted, pulling a boom box out of nowhere and playing Ke$ha at a loud volume as the girls got prepared for the night.
An hour had passed and the girls were having a grand time. All of them had changed into some night clothes to sleep in. Rainbow Dash, dressed in a multicolored tank top and a pair of short shorts that looked like a pair of briefs under her large pregnant belly, had propped herself up with a couple pillows on the edge of the carpet closest to the door, drinking some soda. Fluttershy, who had a see-through, purple nightgown on over a pair of matching bra and panties, was blushing as Rarity continued to comment on how good she looked. Meanwhile, Pinkie, who brought only an extra large tee with a Transformers symbol on it and an extra pair of panties, was playing a card game with Applejack and Twilight. Twilight was wearing a sky blue V-neck that showed the top of her purple-tinted bosom and part if her black bra and a pair of black shorts. Applejack was wearing only a grey tank top and matching pair of yoga pants which showed off her backside and hips extremely well.
"This is pretty fun, girls." Twilight said, cleaning up the cards and placing the deck back in its casing.
"Are you kidding?? This is the best time I've ever had!" Pinkie said, jumping up and down, her boobs and belly jiggling as she did so.
"Careful, Pinkie. Y'all are carrying' precious cargo in there, ya know." Applejack reminded her as she got up slowly to get to the snack table.
"Ah she's fine, AJ." Dash jumped in, leaning up. "Quit being such a worry-uh oh." she started to say before quickly stopping and placing a hand on her belly.
All the gazes in the room turned to Dash, who's stomach started gurgling loud enough for everyone to hear.
"Are you ok, Dash?" Twilight asked.
"Is something wrong, darling?" Rarity chimed in.
"I-Im not sure..." Dash said before the gurgling and groaning got louder and she let out a long belch. "Oh, now Im fine."
"Ugh! How unladylike!" Rarity exclaimed as the stench of her friend's burp filled the air.
"Nice one, Girl!" AJ smiled, bending down and slapping fives with the rainbow-haired teen mom-to-be.
"Yeah it was! Junior thinks so too, dontcha kiddo?" Rainbow Dash asked her stomach, which gave a kick back in response. "That's a yes."
As if on synch, all the girls also placed hands on their stomachs, feeling kicks from their own bellies.
"That's so weird. Every time one of our little ones kick, they all kick." Fluttershy said aloud.
"Yeah, I never got that either. Feels so cool though." Rainbow smiled, rubbing her bulge.
"I betcha it feels even cooler with more than one kid." AJ suggested, looking at Fluttershy, then Twilight. Out of all of them, they were the only two having twins, Twilight just learning the other day her and Flash Sentry's would both be girls while Fluttershy and Big Mac were having one of each.
"Not really....It's just more kicking." Fluttershy answered.
"Still, I bet it feels even better." Rarity added. "It's too bad I can't find out for myself."
"Actually, Rarity, I have a way you can." Twilight spoke up, waddling over to her knapsack and fishing out a small hardcover book and showing her friends.
"Magical Prenatal Studies?" AJ read the title aloud.
"Since Im really into magic, I found this at the town book store the other day. It's a lot of different magical stuff I could do while one of us is pregnant." Twilight explained.
"Like what?" Rarity asked.
"Well, I could see inside your stomachs if I wanted to." Twilight said, raising a hand in front of Applejack's belly and generating some magic. Slowly, a faded image of an unborn baby inside of Applejack's exposed midsection came into everyone's view, while Applejack looked at her unborn daughter in amazement.
"Oh, she's got the Apple family hair!" Applejack beamed, looking down at herself .
"What else can you do?" Rainbow Dash asked, getting into a kneeling position with one hand on her back.
"For one, give temporary back pain relief." Twilight said, snapping her fingers. Almost immediately, all the girl's backs felt much less sore.
"Woah! Cool!" Pinkie said, bending over backwards , exposing her naked boobs and belly as her shirt fell over her head.
"Pinkie, please cover yourself!" Rarity pleaded as the party girl refitted her nightshirt.
"The rest are just temporary symptom reliefs, and then there's this." Twilight said, holding up the book, pointing at a page that read, "Fetal Multiplication".
"What the heck does that mean?" Applejack asked.
"It means, I could make temporary clones of unborn babies in anybody who's pregnant!" Twilight explained.
"Does it hurt?" Fluttershy asked
"Well, your skin stretching out a little more is sort of uncomfortable, but it shouldn't be painful." Twilight reassured her. "I've tested it myself. The most I can go is four kids."
"May I have a try at this?" Rarity asked.
"Do me next! Do me next!" Pinkie chanted.
"Sure! I'll do it for all of you!" Twilight agreed, walking up to Rarity, who excitedly tossed herself into the lounger. "For this to work, I need to be touching your bare belly."
Rarity slowly pulled up her nightgown, revealing her belly and a frilly pair of white lace panties. Twilight slowly placed a glowing hand on her friend's stomach. Rarity felt a tingling sensation inside her as Twilight touched her, and slowly felt her belly and hips widen and breasts began to push outward. After about half a minute, Twilight pulled her hand away and recast the x-ray spell. Rarity was amazed to see two babies inside herself instead of one.
"Oh my gosh! It worked! Im pregnant with twins!" Rarity squealed.
"Of course, you know it's temporary right?"Twilight reminded her.
"My turn!" Pinkie said, bumping her off-balance with her bare belly, which was so close to her, Twilight simply needed to turn her hand at a slight angle to touch Pinkie's tummy. She shivered with excitement as her belly grew outward to the size of twin-pregnancy. She then did the same for Applejack, then Rainbow Dash.
"Ah feel a bit bigger, what about you gals?" Applejack asked, gasping as two sets of kicks in synch with each other prodded against her side.
Sure enough, all of them, including Twilight and Fluttershy who were already pregnant with twins, felt the same ammount of kicks as their cowgirl friend did.
"That's so amazing." Rarity said, visibly astonished."
"You said we could go bigger, right?" Rainbow asked.
"Does this answer your question?" Twilight said, pressing a hand to the center of her belly for a good minute and a half. She bit her lip as the growth started to push her shirt up, her panty lining just barely peaking over her waistband. She began to blush and moan as a creaking sound came from her growing belly before she finally pulled her hand away and fell to her knees, panting and rubbing her belly. "Q-quintuplets. A new personal best."
"Wow, Twi! Y'all are bigger than any of us!" Applejack exclaimed as she kneeled down and patted her friend's belly.
"Yeah. Every thirty seconds the spell is in effect, another clone fetus forms." Twilight explained.
"I have an idea! Let's start a contest to see how big we can get!" Rainbow Dash suggested.
"Does everything hafta be a contest with ya?" Applejack said, raising an eyebrow.
"Actually, I would like to see how much my tummy could hold." Fluttershy said.
"I bet I could beat all of you! Hit me, Twi!" Pinkie shouted, thrusting her bulging belly at Twilight. After about two and a half minutes, Pinkie started moaning. "Okay, too full. That's enough." she said, backing away, almost doubling over as she was getting used to the new weight of her huge stomach.
"Let's see..." Rainbow mumbled as she quickly drew up a chart to see who could last the longest. "If you already had twins, and lasted two minutes, thirty seconds...that's seven babies in your belly now, Pinkie!"
"Wowee! It feels like there's a party IN my belly!" Pinkie giggled as her clone babies all kicked around, causing her entire belly to jiggle uncontrollably. Meanwhile, Dash went ahead and marked Twilight down for her quints.
"So who wants to go next?" Twilight asked.
"I'll go now, darling." Rarity offered, helping Twilight up and sitting her onto the ottoman in front of the lounger. She moved the night gown away from her stomach as Twilight put a hand to it. Rarity blushed as the pleasurable tingling sensation built up inside her and her tummy began to grow. She lasted to the point her nightgown lifted up high enough to go from knee-high, to the point it showed the bottom of her belly and belly button. Her hips widened as well, tightening the grip her lace panties held over her buttocks and womanhood. She began to groan as her belly creaked and grew just past the size Twilight's was.
"Okay, stop! Im getting stretch marks!" She cried as she batted Twilight's hand away and caressed her bloated belly. "How did I do?"
"Two minutes. That's a total of six kids in there now." Rainbow announced.
"Oh darn. I couldn't beat Pinkie." Rarity whined.
"You could go again if you wanted."Twilight offered.
"Not until the rest of us go first!" Rainbow protested. "Let me go next, Twilight!"
"Sure, Rainbow." Twilight said as the athlete waddled over and leaned up against the wall next to Twilight, cradling her pregnant belly in her hands. Twilight began the spell, as everyone watched Rainbow's belly grow, pushing her tank top up and her shorts down.
"Triplets...quads...q-quints..." Rainbow muttered to herself at every thirty second interval, shutting her eyes and biting her lip after a minute. "Six k-kids....Se-seven..." she stuttered as she began to turn red as her belly creaked loudly. "Ooooh...okay okay stop!" she cried, tipping forward slightly. "That's...eight...kids." she panted.
"Well great job there, OctoDash." Applejack joked.
"H-hey! I'd like to see you do better!" Dash challenged the cowgirl.
"Alright then, but don't start cryin' if Ah beat ya." Applejack said, wobbling up to Twilight. "Go on, hon."
Twilight nodded, and put a hand to Applejack's stomach. Everyone watched in awe as she bloated even bigger than Pinkie and Rainbow, her tank top filling up with her equally expanding breasts and her yoga pants drawing tight around her widening hips. "K-keep it goin'." the cowgirl panted, her belly moaning from the strain it was under. " Alright, stop it." Applejack finally said, pulling the hand away. As she went to sit down, a ripping sound came from her pants, which tore from both hips, exposing her bare naked behind, causing her to turn as red as her older brother.
"D-don't look at me! " AJ scrambles as she wrapped a sheet around her backside.
"Relax, AJ. We're looking at your gut, not your ass." Rainbow joked. "So you're in the lead now! Three minutes with nine babies!"
"Wow...Ma granny would've flipped even harder if'n Ah was really pregnant with nine young'ins." AJ smiled, patting her stomach.
"Ok, you're up, Fluttershy." Rarity said, looking at the only girl in the room who hasn't bloated herself yet.
"Oh um...I don't think I could get any bigger than you all." Fluttershy said bashfully.
"Doesn't hurt to try." Dash said, quickly grabbing Twilight's hand and planting it on Fluttershy's baby bump. She yelped as she felt the tingling sensation, followed by her belly pushing out further and further. Fluttershy stood her ground, letting out quiet moans and squeaks as she passed octuplet size. Her belly was coated in stretch marks and her navel began throbbing as her moans drew out longer and belly grew even bigger than AJ's. Her breasts and butt also grew as her naturally C-sized breasts grew to triple D's, bursting the front hook of her bra. Her panties popped off as she passed AJ's size, exposing her ass and all its glory to her friends watching from behind.
"Okay! Okay! STOOOOP!" Fluttershy gasped as Twilight quickly pulled her hand away. The extremely bloated girl fell to her knees, resting her head atop her massive belly, taking deep breaths.
"Fluttershy are you okay?" Twilight asked, putting a hand on her shoulder.
"I...Im okay." she said between panting.
"That was amazing, Fluttershy! You got WAAAAY bigger than AJ!" Pinkie excitedly shouted.
"I lost count. How long did she last?" Rainbow asked. To answer her question, Twilight used the x-ray spell on Fluttershy. Between her bloated breasts, barely being held in her see though nightgown's bra, plus the stretched out panties, Fluttershy and the others gasped to see fifteen babies inside her.
"FIFTEEN??!?!? Damn, Fluttershy! Didn't know you could hold even five!" Rainbow said, shocked beyond belief.
"Twilight...um... Remember when we started this, and Rarity asked if it felt better with the more babies kicking inside?" Fluttershy asked, placing a hand on her tummy.
"Yeah, why?" Twilight asked.
"Well...She was right...but so does this." Fluttershy smiled as she placed her belly up to Twilight's much smaller belly. Both passengers of both bellies began thumping and kicking into each other. Then, all of a sudden, Fluttershy pulled Twilight forward, planting a big kiss on her lips.
"Wh-what the???" Applejack studdered.
Going from wide eyed and confused to accepting it, Twilight placed her full weight on top of Fluttershy's belly, saddling it like she was riding a horse, wrapping her arms around Fluttershy and returning the kiss, grinding against the top of her belly.
"I-I don't know why...but Im getting in on this!" Dash gasped, throwing herself into the orgy, motor boating between Twilight and Fluttershy's breasts, then joining in the other two's make out session.
Next thing she knew, Pinkie had rushed over, putting Fluttershy into a hug from behind as the mother of fifteen sat atop her belly, only to rest her enlarged thighs and back against the top of Pinkie's stomach, then putting an arm around Pinkie's head as the party girl nipped at her neck sensually.
Applejack suddenly felt the lust as well, and dragged her belly to the center of the carpet and began resting the front of her belly against the front of Fluttershy's, while simultaneously using her teeth to rip off Twilight's shorts, revealing a hot pink thong between her and Twilight's ass. Disregarding the underwear, Applejack shoved her face into it, motor boating between the cheeks and causing Twilight to arch her back and let out a moan of ecstasy.
"Okay... Screw stretch marks!" Rarity shouted as she ran to Fluttershy's other side, grabbing one of Twilight's hands and placing it on top of her belly, making it bloat until she was as pregnant as Applejack, who noticed Rarity's growing figure and ceased stratling Twilight's backside to let Rarity sit atop her belly, shoving her face into the fancy girl's womanhood as Rarity grinded on Twilight's ass.
With all six girls touching and going in sanely horny, the kicking was felt by all, growing quicker as the girls drew closer and closer to the climax.
"Oh...Oh God.Im almost th-there!" Pinkie cried out.
"M-me t-t-oo...AhA...ohhhhhh!" Rarity agreed, moaning as AJ's tounge went places it never went before. Meanwhile, AJ rubbed her cooch against Fluttershy's now- outie belly button, achieving penetration and continuing to hump it.c"Ah-ohh my-Ah cant hold it m...much longer!" She yelled from underneath Rarity's belly.
Dash, who was dry humping the back of her own stomach as she made out with Twilight, managed to reach down with her left arm and pleasure herself as she continued making out. "D-don't stop! Don't EVER stop!" she cried.
"Ah...AGH...AHHHH.... I'm just...about..." Fluttershy bit her lip.
"H-hold on, " Twilight said, setting up the spell in both hands, feeling even more bloated than ever as her size pushed Fluttershy's belly out from under her, then caressing her own belly with seventeen kids inside.
"I...win!" She panted as all of the sudden, all the girls' moaned in discomfort as their bellies groaned and gurgled, then pressed outward until they were the same size as Twilight. That just made them even more hotter, as their cries of pleasure got more and more high pitched as waves of ecstasy pulsed through them until a simultaneous orgasm caused them all to cry out from the tops of their lungs. A pool of secretions and mung pooled underneath each girl as they fell on their backs, panting and sweating.
For clothing, all that was left on the six was scarce. Fluttershy's nightgown had went from waist length to the point it looked like a see- through sports bra. Her real bra had snapped back in her original growth spurt, but was held tight between the nightgown tightened to extremeties by her breasts. Pinkie's panties tore during the orgy, and all that was left was her now snugly fitting t-shirt, coming to rest halfway up her exposed boob flesh. Rarity was virtually naked, as all that remained were the torn straps of her lace bra which found it impossible to hold her growing figure in any longer. Rainbow Dash and Applejack's bras were able to hold on, but only barely. Dash's bra was on the brink of bursting, and her boxer shorts which she wore underneath her regular pajama shorts now looked like a pair of briefs a few sizes too small on her now expanded waist and ass. AJ's rack somehow didn't grow as much as the others, and was able to remain inside her bra, although the edges of her nipples poked around the cups. Twilight ended up taking the least loss to her nighttime wardrobe and was left a pair of socks, elastic panties and matching bra that somehow held on throughout all the fun.
"Oh my...I don't know who made that spell...but it was amazing..." Rarity gasped, rubbing her enormous stomach.
"Ah can't agree more even if ah tried." AJ agreed, struggling to lean herself up against a nearby wall, allowing her massive belly to rest in her naked lap.
Twilight, curious as ever, looked at the page of her book with the spell on it again. "Well that explains a lot." she said in a low voice.
"What is it?" Fluttershy asked, trying her best to get into a kneeling position with her belly in the way.
"I must've never read this part." Twilight answered before reading aloud from the book. "Note to users of this spell: use caution, as the fetal cloning spell can double as an afrodesiac to same-gender targets after prolonged use."
"Afro-wha?" Rainbow spoke up, after finally calming her breathing from the climax.
"It's what made...that thing we just did happen." Fluttershy said quietly, blushing until her skin was as red as the boy who knocked her up in the first place.
"Well...I'm not complaining." Pinkie said, giving her tummy a rub. "That was the best I've ever had! We should do this every week until our kids are born!"
"Pinkie, I don't know if we could handle that.... " Rainbow started before pausing as each of the seventeen babies inside her started kicking. "Oh who am I kidding? This is too good to...do...only once!" she finished between kicks.
"Then ah guess it's settled. We'll do this every Friday night up until our due dates." AJ announced.
"Fine by me." Twilight agreed, followed by concurring remarks all around.
"So Twilight, how long did the book say these bellies last?" Rarity asked looking at her new size in a mirror. "I can't go out in public looking like a pregnant whale."
"Ditto." Dash agreed. "It feels awsome, but Soarin would flip if he saw His kid somehow ended up THIS big inside me."
"Don't worry, it dissipates after sunrise." Twilight answered, waddling up beside her, and feeling her belly. She then overlooked the girls with a 'Come Hither' look on her face. "Now...who's up for round two?"
