Twilight invites the Cutie Mark Crusaders over so she can test a new spell on some eager fillies, and they all get much more than they bargained for.

Twilight has a new spell that's almost ready to show to the princesses, one designed to grant mares a package fit for a stallion. Only problem is all non-battle spells need to be tested on foals first to determine their safety and effectiveness. Luckily Ponyville has three little fillies who are all too eager to try new things!

Note: I haven't been keeping up with the show since S4 so for the sake of not wanting to portray things too inaccurately (even if this is self-indulgent smut) this takes place around season 2, pre-Alicorn Twilight and pre-Cutie-Marked Crusaders.

CONTENT WARNINGS
All chapters contain, to at least some degree: Foalcon, futanari, transformation, and casual nudity (like the show, ponies only wear anything more than a hat on special occassions, but unlike the show they've got genitals)
Scootaloo's chapter focuses on the transformation itself and her building orgasm and contains musk and an accidental facial
Apple Bloom's chapter focuses on her giant schlong and excessive precum and contains penis awe, precum leaking and collection, and the closest thing to sex this story has (a hindhoofjob, autofellatio, and frotting as they explore their new anatomy)
Sweetie Belle's chapter focuses on her internal thoughts and mild humiliation and contains reluctance, light SPH (small penis humiliation), and a continuation of the playful exploration from the previous chapter

Arrival

Twilight perked up from her reading at the sound of a hoof tapping on wood and hopped out of her bed on the loft to answer it. The three young blank flanks were at the door, ready for another try at getting their cutie mark. “Thanks for coming to help me today girls! I have a brand new spell I’ve been working on that's just about ready for publishing! Only thing is it hasn't been tested on a foal yet."

“The pleasure’s ours Miss Sparkle!” Applebloom said with unbridled enthusiasm. Scootaloo and Sweetie Belle nodded and gave a playful salute.

“So what is it exactly we’re testing this time?” Sweetie asked with just a hint of derisiveness in her tone. Despite being a unicorn herself, she was a bit reluctant to do any magical favors for Twilight since the Want It, Need It incident. To her, magic was best used for simple levitation, like she and Rarity used around the boutique. Still, she wasn't one to miss out on an opportunity for a Cutie Mark.

A sly smirk spread across Twilight's face, and she blushed. "Well you see, it's not exactly a spell for foals, but of course we all know foals are gonna get their hands on it anyway. Normally there are some specially trained little ones the princesses can call on for this task but I assured Celestia I knew just the fillies, even if they lacked the training. Do you understand?" The trio nodded, eager as always to not only try earning their marks, but to show their maturity as well.

And so Twilight reared up on her hind hooves, balancing on two legs as best she could, and showed off the fruits of her laborious research. Below her petite breasts sat a package fit for a stallion. A deep, dark, plum color, the velvety skin of her sack was pulled tight around two egg-sized testes. Just above, a wrinkled sheath, shiny with sweat. The flat head of her shaft, along with a couple inches below it, were exposed as Twilight reveled in showing off but tried to restrain herself from letting it all out. Her cock was a slightly lighter purple than her sheath and balls, and a bead of precum had formed at the tip and was slowly sliding down the length. The Cutie Mark Crusaders looked on in amazement at the biological marvel before them, stunned by the prospect of getting ones of their own. Twilight's new additions jiggled as she struggled to steady herself, until she eventually lost her balance and fell back to the floor with a loud clack of her horseshoes, her balls thrust into a forward swing by the sudden motion. She gasped in a mixture of pleasure and pain as they slapped against her breasts, still not used to how much they swayed or how sensitive they were. She'd only activated the spell on herself the previous night, and after testing the goods a time or three, promptly passed out.

“So, who wants to go first?"

Scootaloo - Ready to Ride

There was much um-ing and ah-ing as the trio came to terms with what they were just shown and what they were about to have done to them. Sweetie Belle shuffled on her hooves anxiously, always thinking of herself as a prim and proper lady, while Apple Bloom drooled and tried to sneak some more peeks at Twilight's new gear. Finally, Scootaloo raised one hoof and stepped forward, her wings twitching with anticipation.

In the middle of the library was a horizontal bar supported on two poles, each of which had multiple notches in them for placing the bar at different heights. “Alright then, just put your forehooves up over the bar and relax." Twilight instructed. "I should warn you this spell's a bit more intimate than you may be used to. You might feel a slight prickling sensation... Ahem, so to speak!”

Scootaloo did as she was told, and after some minor adjustments, her head was lifted in a position that was both comfortable and gave Twilight - and the other two Crusaders - a proper view. A purple glow surrounded the space between Scootaloo’s budding teats and her virgin pussy, heating the air around her groin as though a cloud of steam was gathering underneath her. The blob of arcane energy pulsated around in a massaging motion as Twilight sharpened her focus. She needed time to warm up - after all, this was only the second time she'd tried manifesting a new manhood. The massage also served to relax Scootaloo in body and mind, making her more susceptible to the changes. She closed her eyes and took deep breaths as two small bumps started to form just above her clit. Pressure built within as these new orbs swelled inside her body, almost painfully, like a stomach cramp. Once they reached a sufficient size Twilight used her magic to stroke downward, stretching the flesh out to make a roomy pouch for them. Her wings shuddered with shock and pleasure when her still unfamiliar testes slid into their new home with ease. This sack, her ballsack, was practically devoid of fur, exposing her mahogany brown skin.

“Mhm, I see, I see.” With magic still pulsating around Scootaloo’s nethers, Twilight quickly marked down some notes on her clipboard. “All working as expected so far! Any questions?” Scootaloo and Sweetie Belle shook their heads, while Applebloom continued to watch intently with envy. The balls now in place Twilight continued swirling her magic around them to refine their shape and size.

All the while Scootaloo was feeling increasingly horny. The ethereal cloud of magenta running across her skin felt amazing, like a loving mother's tongue. She bit her lip in a vain attempt of stifling a moan, but the soft squishy sounds of her clit's rhythmic winking betrayed her. Twilight smiled. "Perhaps it's working a little too well. I think the more intimate nature of this casting method may be a little much for a filly." She jotted down some more notes as she continued.

"This is a little technique I picked up from Zecora called fleshcraft. It really helps to define all those nooks and crannies," she said as she added a small crease to the center of the sack, defining the pendulous balls in their separate chambers. She continued to infodump about the magics at play as she worked. "Normally this would be done with a cream of some kind, but the alchemical processes of zebra magic adapt quite easily into the unicorns' arcane techniques. And the best part is that it takes the wants of the target's subconscious into account as well as genetics, so not only can it provide more customization, but there's also less chance of funny business from the caster. It's very much a spell for pleasure, as opposed to most transformation magics which were designed for the sake of quick disguises or incapacitating enemies."

Twilight rambled on, ignoring Scootaloo's quickening breath and loudening whimpers. As the volume increased it became harder to brush off, though, so she decided to check in. "How do you feel about this so far? Need me to stop?" Scootaloo shook her head again as her wings quivered. With a final flourish of magic swirling around them, the pair of balls settled into a modest chestnut size, fairly average for a colt of her age. When the magic receded, her balls immediately became rather cold, and just as quickly as they descended, the skin tightened around them and became smooth. "Alright then," Twilight grinned. "Time for the main event."

Twilight's magic swished up to where the ballsack connected to the groin and formed a ring just ahead of it. It glowed brighter and swirled around the ring, leaving a trail of light and gradually extruding out a sheath. She knelt to the floor and stuck her head under the filly's belly to get a closer look at her work. Immediately she noticed the sweet and savory odor of a stallion ready to rut wafting around her head, emanating from Scootaloo's balls. "Woof..." Twilight said under her breath, immediately clearing her throat to obscure the embarrassing utterance. The air was thick with heavy musk, and she couldn't hide the effect it was having on her as it assaulted her senses. Scootaloo must be in heat - she thought - perhaps her first. She hoped this temporary alteration to her sex wouldn't interfere too much and embarrass the filly, though at the same time, it would be valuable for scientific inquiry. The sack had quickly developed a sheen of sweat which highlighted its contours, and Twilight couldn't help but take pride in her craft. Or maybe that was just her arousal from taking in the intoxicating scent. Regardless, she quite liked the look of them. "Ahem, i-it's a lot like pottery, you know." She said in a vain attempt to distract herself. "Perhaps you should try getting a cutie mark for that too if spell-testing doesn't work out"

Scootaloo's head vibrated up and down in agreement as she struggled to reply. "Mm-m-ayb-be!"

The shaft continued to come out, and as it did, an unwavering erection revealed itself. A deep mahogany brown, nearly black, Scootaloo's new member was on the average side for a colt at around 8 inches. It was a little bit thin, but the way it flared out more than made up for that. As of yet though it was a perfectly smooth rod of meat, lacking much of anything to make it a proper dick. Twilight's magic ran up and down the length sensually to remedy this, incidentally jerking her off in the process. She got to work on adding features, starting with the medial ring. Scootaloo started to buck into the glowing ring, hind hooves tapping on the hardwood floor as she tried to contain herself. Her new cock started to pulse wildly, Scootaloo slapping it against her belly. Twilight knew what this meant, but made the mistake of thinking Scootaloo could hold it. Ignoring the twitching she persisted and got to work on shaping the tip.

Suddenly, it all had to be let loose. As the finishing details on her flare were being added - the most sensitive piece - Scootaloo had her first orgasm as a futa filly. She suddenly thrust forward and drove her cock up the bridge of Twilight's nose, leaving her balls right at her nostrils and forcing her to huff their scent. Thick ropes of cum squirted out without warning across Twilight's face. They streaked in her mane and splashed all over her fur. She had to close one eye quickly to avoid a shocking sting, and a few strands dangled down over her snout. The unicorn's face took on a shocked expression, mouth agape, but it was quickly replaced by a smile trying to suppress giggles.

Scootaloo, however, was mortified. "I'm so sorry Miss Twi!" She slurred out in her post-nut haze. Her cock was still pushing out the last of its semen, pulsing up and down and tapping Twilight on the nose. Still yet, more cum dribbled out straight into her fur.

Twilight licked her lips of the virile seed before she levitated a nearby hoof towel to wipe herself clean. She was prepared for this to happen with at least one of them, but she wasn't expecting it to be so hot! The taste of Scootaloo's cum lived up to the smells - salty, sweet, and smooth. She was getting dizzy with lust and couldn't help herself much longer. "D-don't worry about it, I know from experience this procedure can be a little intense! Here, let me get you cleaned up." Without giving Scootaloo the opportunity to question what was to happen next, she took her shaft into her mouth from the side and slid her lips up the length. This coaxed out the last drops, which she resisted consuming to instead capture in a vial for later research. Scootaloo nearly collapsed - she would have were it not for the beam she was held up by. "Mmm, good girl, you've been a very good test subject!" Twilight commended the filly as she let her off the bar and sent her back to her friends with a slap on the rump.

"So, who's next?"

Apple Bloom - The Big Apple

“Me next, me next!” Apple Bloom jumped in place with glee. Seeing the half-lidded expression on Scootaloo's face, she knew she was in for something fun.

Twilight had a glint in her eye, happy to see the enthusiasm come back out. “Alright my eager little helper, hooves up just like Scoots did.”

The process began much like before, with two bumps slowly expanding beneath Apple Bloom's teats. Her breasts were slightly larger than Scootaloo's, the Apple family being notoriously endowed. Twilight wondered how that would affect the spell. As the balls quickly plopped out into the sack, they stretched the skin tight as they grew slightly faster than the flesh around them. Apple Bloom winced, and Twilight quickly made efforts to speed up the growth of the sack. "Sorry. I'm still getting the hang of this." She took some more notes, immediately taking notice of the size disparity between Apple Bloom's testicles versus Scootaloo's and her own. Her attention divided, the pair of balls continued growing unchecked, pulsing with purple energy from within. By the time she looked back they'd grown to the size of grapefruits. Apple Bloom's scrotum now hung low, dangling nearly to her knees, and its fur never thinned, instead leaving it covered in the same fluffy coat as the rest of her.

Apple Bloom rocked her hips side to side excitedly, feeling her pendulous sack slap back and forth between her thighs with a dull plap each time. Twilight's eyes got wide, and her magic flickered as her concentration was broken. "I-, um... think that's enough of that." Twilight said, reaching out a hoof to examine her handiwork. She lifted the weighty, egg-shaped orbs, and traced along the prominent vein that adorned each one. "Let's see what else you have in store."

Twilight made short work of forming the sheath, stretching it outward from the center like she was sculpting a vase. Its color, she noted, was split between brown and tan, and much to her surprise the width settled to about the same as Apple Bloom's hoof. The floating magical essence once again went inside the sheath, but rather than disappear it stayed perfectly visible in the gaping hole. This time for the cock she decided to work on the details as they came out, rather than apply them once a featureless tube had formed. First came the flare, which immediately started to stretch out the sheath as it formed. Its broad, spade shaped top quickly took shape, and details like the urethra and nubbed edges quickly followed. It wasn't long before it exited from its confines with a wet pop. As it did, a bead of precum was flung onto the floor, with another string waiting to fall from the tip.

"Oh, do be careful not to drip on the floor too much, Spike'll have to mop all that up. Actually..." Twilight's voice trailed off, and she cut off her magic and ran to her kitchenette. She soon returned with a large glass bowl, which she placed on the floor beneath Apple Bloom after wiping up the small splatters of clear, slimy fluid. Once she was sure there'd be no more mess, she continued, extruding out the shaft. Each time she grabbed it by the base and slowly stroked downward, another quarter inch appeared, and much to her surprise, another dribble of precum came out. Apple Bloom moaned in subdued bliss each time. It took until inch six to reach the medial ring, which once completed formed a sizable ridge as wide as a fully engorged flare.

"Wow, that's where you put the ring?" Sweetie Belle cried out in amazement. This was far different looking than what she'd seen in her schoolbooks. She never imagined they could be so big.

Twilight nodded, but seemed confused. "Yeah, I can feel there's a lot more left."

Apple Bloom's fat maredick continued to snake out of its sheath, bit by bit, dangling freely between her legs. Its coloration was mottled brown and tan, with large splotches of the lighter hue covering the top third, a patch on the side, and little speckles around the rest like splattered paint. By the time it was done, it was nearly touching the surface of the collected precum in the bowl. That is to say it was nearly as long as her legs, and considering she stood at just under 3 feet, that meant it settled in at around 14 inches. "Sweet Celestia. Looks like you take after your brother." Twilight commented.

"Apple must not fall too far from the tree!" Scootaloo shouted, always the jokester of the bunch. She and Sweetie Belle stood back watching in awe as inch after inch of thick piebald flesh emerged from their friend. Apple Bloom blushed and covered her face with a hoof, secretly enjoying all the attention. In all honesty she'd always been amazed and a little jealous of Big Mac. That fact, combined with her gifted lineage, Twilight's expectations of what it would look like, and Twilight's arousal from Scootaloo's musk subconsciously influencing her magic all added up to a cock fit to rival his, even at her diminutive size. She flexed it with pride, flinging yet more pre onto Twilight's nose, which she casually licked off without saying a word.

"I think that's about enough for you little missy. Go on over and stand with Scootaloo." Twilight said as she retrieved the half-full bowl and set it on the table with the vial of Scootaloo's cum. "And ah, this sample should be more than enough, but if you'd care to... finish, that'd be helpful. Just try to keep it tidy." As she spoke she looked into the kitchen and levitated another slightly smaller bowl to the main room for the job. She hoped it'd be big enough, or she'd have to do a lot of cleaning or a lot of explaining.

Apple Bloom returned to her place by the door and started trying to get her hefty member hard. The sheer weight of it made that pretty difficult, but Scootaloo was happy to help. She laid down on the floor underneath and started to play with the cock with her hind hooves. She batted it around awkwardly for a while but it soon stiffened up enough to grip and stroke. It swung upward and back down rhythmically as it reached full mast, gaining a couple inches, and dripped a line of its warm precum down the middle of her body. Not just her belly and chest, she realized - it also painted down her own hard horsecock, adding to the already shining sheen it seemed to permanently have. She reached a front hoof down to stroke it. Her mouth opened as she felt her breath quickening.

Apple Bloom's cock now drooped down in her face, and the flare swelled intimidatingly as a drop of pre fell on her tongue. "H-hey, watch it!" She said teasingly through laughter. Now that it was hard, Scootaloo could easily push Apple Bloom's dick up against her belly, where it proved long enough to nearly pass her chest. With a little stretching, Apple Bloom could simply look down and lick the head to prevent any more leakage, savoring the salty juices. Meanwhile Scootaloo humped upwards, grinding her lubed up dick against the one twice its size above her.

Twilight smiled at the pair as she watched them enthusiastically enjoy themselves, but her mindless voyeurism was interrupted by seeing a hint of white in her peripheral vision. "Oh! I'm so sorry Sweetie, I didn't forget about you. Step on up!"

Sweetie Belle - Precious Pearls

Sweetie shuffled on her hooves as Apple Bloom returned to her spot by the shelf with her and Scootaloo, knowing what would come next. Though she was happy for the delay, and the show, as she too was enraptured by the performance the pair beside her was putting on. She jumped as Twilight called once more for her attention "Sweetie Belle? Come on up, it's getting late."

With a nervous look in her eyes, Sweetie Belle walked up to the adjustable bar and put her hooves up. Noticing they rested above her head, Twilight brought the bar down a couple notches to make her more comfortable. With that, she was prepared to complete the final spell of the evening, which she was more than grateful for as this spell proved to be quite taxing. Most spells tended to be on the first draft.

Twilight had gotten more than enough practice by now to speed the spell along and have them on their way by sundown. Once she centered her focus on the biological signature, Sweetie's balls dropped down almost immediately. Though, despite forming quickly, they took quite a while to actually grow, and didn't quite make it to matching Scootaloo's. Wispy snow white fur over the pink flesh of her scrotum lent it a pearly pastel hue, fitting for the little marbles within.

Next as always came the penis itself, a bubblegum pink rod proudly emerging from a dull gray sheath. It began fairly thick, just thicker than Scootaloo's, and started to grow inch by inch as usual. However, as Twilight worked she struggled to get the features to come through. The medial ring would only grow to a dull ridge, and the flare rounded forward and outward more than the others, but didn't add much width.

Then, without warning, the magic fizzled out in a shower of lavender sparks. Sweetie squeaked as an electric vibration ran through her new appendage. It slapped against her belly, or rather, right between her flat breasts. The magical equivalent of a short circuit rebounded and sent shudders down Twilight's body as well. She furrowed her brow. "Hrm, that's odd." She said to nobody in particular. She tried again, but still the magic refused to finish the job. It fizzled once more sending an electrical pulse down the length of the shaft, which caused Sweetie Belle's knees to buckle and a small squirt of fluid to spray from her pussy.

Twilight started to flip through her papers, checking over her formulas and scrawling down notes while muttering to herself. "Am I low on energy? Is she resisting the spell? Is she too young? Think, Sparkle..."

"Wh... what's wrong?" Sweetie asked with shaky breath, concerned for what magical mishap may have befallen her this time. Her concerns weren't helped by the unmistakable sound of Scootaloo - still on the floor but taking a break from servicing A.B. to take a peek - snickering behind her.

"Oh nothing! Nothing. These results are just a bit uh... Underwhelming." Twilight said, quickly turning her attention to the filly to save face. She explained the situation as she brought a mirror over for her to see. "It's not bad for a foal, let alone a filly obviously, just not what I was expecting. Perhaps you're a late bloomer, or your lineage runs a bit small, or your femininity made the spell not take as well. Like I said, it does take into account the target's desires as well." Twilight rambled with a nervous energy, trying to cheer up the filly and brainstorm possibilities to prevent that from happening again. "Regardless, I'll be sure to make the spell compatible with a more basic growth spell in the next iteration"

As she gazed at her reflection, Sweetie's mouth dropped open to be quickly covered by a hoof. Sure enough, sitting tight to her body was a downright miniscule pair of balls, no larger than a couple of gumballs. Similarly the little speck of pink she could see was comparable to a fun-sized candy bar. Even Button Mash, who she certainly didn't get with for his meat, was slightly larger than her. She didn't start the day wanting this, and she knew it was temporary, but she still came out of it disappointed. A deep blush crossed her face, and she tucked her tail to hide her shame from her friends. Its well conditioned hairs tickled both her female and male anatomy, forcing meek moans past her lips.

Twilight noticed Sweetie's discomfort and tried to be assuring. "Oh, it's nothing to be ashamed of Sweetie Belle! It works all the same, I would imagine." Despite her best efforts, though, she struggled to meet Sweetie in the eyes with the display just over her shoulders. 'Why should they get to have all the fun?' She thought. Scootaloo's hypnotic musk and Apple Bloom's stunning size had really done a number on her, and it was getting harder to hide. "Why don't we find out?" She asked, as she slithered down below Sweetie's belly and popped the petite pink popsicle into her mouth.

Sweetie Belle jolted with a yelp. She was no virgin, but this felt far different than she could have imagined. The sensation of being engulfed in something so warm and wet was nearly as good as the sensation of being filled. And her size, while disappointing, made the plush tongue gliding side to side underneath her filly dick feel even bigger and more pillowy. Twilight expertly sucked on the member like she'd studied and practiced, taking it to the sheath with ease. Plenty of room to spare, she went further, engulfing the balls into her mouth as well. Some gentle nibbles and prideful hums later, Sweetie Belle was quivering up a storm and struggling to stay grounded. Her clit winked uncontrollably and Twilight tasted the first drops of her salty reward. It wasn't long before she finally came, and her hind hooves lifted up off the floor, leaving her supported only by the bar. Her eyes shut tight and mouth opened wide, but no sound emerged but a raspy gasp. Down lower, though, her legs twitched at either side of Twilight's head, and juices from her marehood ran down her legs in torrents. Twilight moaned, finally satisfied to get the cum she so craved. After all this her own plum-colored shaft was raring to go - she'd have to take care of that later before getting rid of it.

Across the room, Scootaloo was kneading Apple Bloom's sack with her hind hooves while using her front hooves to stroke it up and down, in time with the pace of her simultaneously humping it. She held her mouth open and was trying her best to catch the near constant stream of pre, but some inevitably fell on her face and became caked in her mane. To the untrained eye one might think she was worshipping it, but they were just two kids exploring their bodies and having fun.

"Buck, Ah'm gunna..." Apple Bloom's accent heightened in the moments before her orgasm. Meanwhile, with her mouth still full of Sweetie seed, Twilight's eyes shot open in shock.

"Mmh! Uh-uh!" Twilight exclaimed through a mouthful of cum. She was so preoccupied with Sweetie Belle she'd forgotten the ticking time bomb that was about to repaint the library at any second. Her horn's magic flickered to life and shot a bolt straight for the ropes of milky filly cream shooting from Apple Bloom and Scootaloo's cocks, desperate to save the floor from a sticky demise. Two orbs of energy collected the cum from each of them as they spurted out in tandem. They finished shortly, with Apple Bloom lasting a fair bit longer until she collapsed onto her spent partner, whose dick remained at attention despite all odds.

Twilight drifted the magenta orbs, now full of swirling white goo, over to the table and poured them carefully into containers. Scootaloo's went into a second vial, while Apple Bloom's required two beakers. Sweetie Belle's, she reluctantly spat into another test tube. She hoped the cross contamination with her saliva wouldn't interfere with... whatever it was she was planning on doing with those samples. She realized now she had no plan for them, but she could always think of something fun if there was nothing to research them for.

Sweetie Belle finally returned to her place with the other two newly christened futa fillies. As much as she hated to admit it, the release did wonders for her mood, easing her anxieties immediately. And the other two Crusaders were too worn out to keep teasing her, even if they wanted to. Still though, this whole day had been a bit too weird for her liking, and she was eager to get back to normal.

Farewells

"Alright you three, I hope you've had fun today." Twilight said with a smile.
"But we didn't get our cutie marks!" Apple Bloom whined.
"Oh, I'm sure you'll get them soon." She tousled the little farm filly's mane. "It's time to get you back to normal though. Can't exactly have you running around with those things without knowing how to control them."
"Finally!" Sweetie Belle groaned.

Twilight stood in front of the trio and localized her magic around each of their members. As with most transformation spells, the return trip always takes far less concentration. The body just innately wants to return to its original form, and just needs a little push. But Twilight's face soon turned to a puzzled grimace as she couldn't feel any change. She tried harder, her magic glowing brighter beneath the Crusaders' bellies. She even broke into a sweat, but still, no matter how hard she pushed herself she couldn't get their dicks to go away.

"That's... odd..." She said panting slightly, punctuating it with a nervous chuckle as she checked over her notes. Zebra magic was quite a bit different foundationally than unicorn magic, and while she was able to adapt the effects of what was originally a cream into a spell, it was dawning on her that a spell couldn't just be washed off. Of course she'd have realized this if she'd tried to get rid of her own alterations first, but she'd simply assumed she could do it without testing in her hubris. She'd practically forgotten they were there anyway, the changes feeling more a part of her with each passing hour since the previous night. "I'm sorry girls, it looks like you'll have to live with those for a while. Not too long, just until I can talk to Zecora and work out the kinks of the counterspell."

All three Crusaders' jaws dropped.
"What's AJ gonna think when she sees?!" Apple Bloom exclaimed. Of the three, she'd have the hardest time hiding the change.
"It's gonna bulge in my flight school uniform!" Scootaloo complained. The scents that arose from the four hormonal ponies over the past couple hours were already causing her cock to stir into action again.
Sweetie Belle shuffled on her feet in silence. She was thinking about what her boyfriend Button would think.

"Girls, girls, settle down. I'm sure everything will be fine. The ponies of Ponyville are very understanding folk - I would know. And I'll be sure to get this fixed by Monday so you won't have to go to school like this or anything. Just... If anyone asks, tell them you got into some poison joke." Twilight grabbed three small coinpurses in her magic and floated them in front of the fillies - their payment for a job well done. each had a leather cord attached to easily hang around their necks. "Now here, two dozen bits each as promised, and a couple of chocolates as a bonus. Also, to help you out in the meantime, take these."

Twilight levitated down some condoms and a pair of lacy white panties down from her loft - both of which were very rarely used. "Apple Bloom, since you're a real leaker, wear one of these so you don't make such a mess." She instructed while using her magic to pull the squishy peen back out of its sheath just enough to put the blue translucent latex sleeve on it. It dripped into the reservoir tip before retreating, and Apple Bloom could only hope they were stretchy. They were, of course. This wasn't the first time Twilight had used sexual magic, and with the few flings she's had she discovered a fondness for boosting their cum supplies. "Sweetie Belle, it's not much, but it should cover you up and still blend in." She spoke in a sweet tone that didn't match the unceremonious magical lifting she gave her to slip the panties up her legs. They were heavenly soft, and on account of the lace, allowed the fur to poke through for better blending. They were tight, but they (un?)fortunately didn't have to contain much. "Scootaloo, uhhh... just keep your wings down." She said apologetically. She didn't have anything to deal with this situation. Usually she'd just 'go for round two,' but that would be a temporary solution that likely wouldn't last until she got out the door, let alone for two days.

And with that, the Cutie Mark Crusaders humbly left the library, tails tucked and knees together. The sun was setting, which meant it was time for each of them to head home. They were all anxious to see what new developments their changes would bring to their lives.

Author's Note

Don't worry, they'll adjust well enough, and everyone's going to be much more accommodating than they might think! I've got a sequel planned eventually, but this took a lot of time and I've got some other things I might want to write first, so it may be a while. Unless of course anybody would like to help out~

Regardless, I hope you've enjoyed my first foray into FimFiction! Feel free to leave any corrections, questions, or suggestions for other stories you'd like to see from me in the comments
