Growth Spurts

Chapter Three: The Stallion in Me

Barely two minutes after her sprint to the schoolhouse, Apple Bloom was sprinting right back out of it, retracing the same old path she walked every day and putting as much distance as she could between herself and the shocked stares of her classmates. She felt the eyes of everypony in town on her as she ran, but it didn’t so much as slow her down, not even when she was clear of Ponyville proper and running down an empty road toward the edge of town. All that mattered was getting back to the farm, somewhere quiet, somewhere private, somewhere safe. She was fortunate that she had the route so completely memorized that she could follow it on pure, thoughtless instinct, because her conscious mind was raging uncontrollably.

A colt.

She was a colt.

How in Celestia’s mane had she become a colt?

Celestia? Mmm, so close, my dear, and yet so very far.

The ominous words immediately rang in her head, and the clear and obvious solution swiftly presented itself.

Discord.

Somehow, for some reason, he had done this to her. It had to be. Twilight Sparkle herself had said once, years ago in that magical duel against the Great and Powerful Trixie, that even as powerful as she was, she couldn’t change somepony’s gender. But Discord… he defied logic and reason and the very laws of physics on a daily basis. It was entirely within his power to do something like this; and she couldn’t ignore the convenient timing of her recent encounter with the creature the previous afternoon, either. It had to be him. There was no other explanation. But why? Why turn her into a colt on top of everything else he’d already done?

You want a new boy in your class. I can make it happen.

Oh no.

Estrus will be the last thing on your mind.

Oh goddess.

There will be a new little colt in your class when you arrive at school.

Of course.

Discord hadn’t known about Spike starting school with them after all. That had just been a freak, innocent coincidence. This… this had been his true plot. Spike wasn’t the new colt in class.

Apple Bloom was.

Of course. It explained everything. The extra muscle, the slightly larger body, the change in her voice… even how good she’d felt this morning. It all fit. Boys didn’t go through estrus. If she was suddenly a boy, all those needs and urges and mare-specific hormones would be gone in an instant. If she was a suddenly a boy, then…

…Then there would be a new boy in the class when she arrived at school.

Apple Bloom could barely think about it without snarling. She’d been tricked. Again.

Unbelievable. She’d really thought he’d changed. For the briefest of times, she’d truly believed he was actually turning over a new leaf and attempting to use his influence for the good of Equestria. But no. It had all been a lie. An elaborate hoax spun by a master con-artist, setting her up to become the butt of some absurd joke at best, or who knew what kind of sinister plot at worst. And now she was going to suffer for it. She couldn’t imagine the kind of punishment she was going to get for disobeying her sister and trusting Discord after being explicitly told not to. It wasn’t fair, she was trying to give him a chance to be nice and helpful, it wasn’t her fault he was still a no-good, lying, deceiving psychopath. To think that Fluttershy of all ponies would actually be friends with a creature like that--

Apple Bloom skidded to a halt.

Fluttershy!

Indeed, just ahead of her down the road, a familiar pink-maned Pegasus mare with a butter-yellow coat was trotting along toward the town marketplace, smiling to herself, calm and care-free. Fluttershy was easily the nicest, kindest pony in all of Ponyville, and if anypony in the world really could be friends with a creature like Discord, it would most definitely be her. She wasn’t the bravest pony around or anything, but when the safety and well-being of her friends was at stake, she would always step up to their defense.

Apple Bloom lit up in relief. That was the answer! Fluttershy would be able to rein in Discord and make him fix things! She could get back to normal right away, and nopony would have to tell Applejack what had happened and get her punished!

Unless they weren’t really friends, of course. For all she knew Discord had lied about that too. If that was the case she would be confessing for nothing, and Applejack would discover the truth just that much sooner. It was worth the risk, though. At the very least, Fluttershy would be understanding and sympathetic and not get angry at her, and might even promise not to spill the beans about what she’d done. She just needed to catch the mare before she got into a more crowded part of town…

“Fluttershy!” Apple Bloom called out, jogging toward her.

The older mare jumped a bit mid-stride and turned curiously toward the unfamiliar voice. Apple Bloom couldn’t blame her for being startled, she barely recognized her voice now herself. “Y-yes?” she answered in a near-whisper, her eyes landing on the young colt trotting up to her, and relaxed slightly. “Hello… um, can I help you?”

“Yes! Yes, please, Ah need yer help, real bad!” Apple Bloom pleaded.

“Oh, my, um… a-alright,” Fluttershy said after a moment of surprised pause. “How can I help you, um… erm… I’m sorry, I don’t think we’ve met before… have we? Oh but, wait, you knew my name… have we met before and I forgot? I’m sorry…”

“No, no, Fluttershy, it’s me!” she said, dropping her own voice and looking around to make sure nopony else was in earshot. “It’s Apple Bloom!”

“…Apple Bloom?” she echoed, blinking down at the filly-turned-colt. “…Um…”

“Ah swear, it’s true, ya gotta believe me! Ah got turned into a boy an’ Ah really need yer help ta get changed back!”

Fluttershy stared down at her for a while, looking her over in honest surprise. “…W-well… goodness… you do sound a little like Apple Bloom… and you look a lot like Apple Bloom…”

“That’s ‘cause Ah am Apple Bloom! Look, Ah’ll prove it! Mah best friends are Sweetie Belle an’ Scootaloo, an’ together we’re the Cutie Mark Crusaders, an’ one time we all had a sleepover at yer house an’ you sang us a lullaby an’ Sweetie Belle totally took it over, an’ then we got lost in the Everfree Forest and ya came lookin’ for us an’ saved us from gettin’ turned inta stone by a cockatrice an’ ya almost got turned yerself but ya fought it off just by starin’ at it--”

“Oh my gosh, you really are Apple Bloom!” Fluttershy gasped, swiftly convinced by the story.

“Ah told ya!”

“Goodness, but… w-why are you a colt now?”

“It’s ‘cause of Discord! He turned me inta one!”

“Discord?” Fluttershy echoed, and then swiftly shook her head. “Oh no, you have it all wrong, Discord wouldn’t do that, not anymore. He’s changed. He’s trying to be good now. Actually, just yesterday we heard you shouting and he went to help you…”

“So ya really are friends?” Apple Bloom pressed. Apparently he hadn’t lied about that after all.

“Oh yes, we’re very good friends now. And I’m sure he was happy to help you… um… did he help you?”

“No! It--… well… sorta, but… Ah didn’t want this kinda help!”

Fluttershy frowned confusedly. “Um… maybe you should start at the beginning…”

Apple Bloom sighed impatiently, but complied, giving her a quick and – for both their sakes – slightly censored version of the events of yesterday afternoon. Fluttershy listened patiently through the whole story, and her frown slowly became more pronounced with each word. By the time she heard the end of the story she looked outright disappointed, slowly shaking her head back and forth.

“…An’ so that’s the only reason Ah can come up with, nopony else woulda done this, or coulda done it…” Apple Bloom finished. “Please Fluttershy, you’re friends with him… somehow… you gotta get him to fix me! …And, um, don’t tell mah sister about it?”

Fluttershy let out a quiet sigh of her own. “Well, Apple Bloom, I promise I won’t say anything to Applejack, and I’m very sorry Discord did that to you… he really has changed, I know he has, but… well, he just can’t resist playing pranks on ponies still, sometimes.”

“Pranks?! This is his idea of a prank?!”

“Oh yes, I’m sure of it… he never does anything harmful or dangerous, but… well, sometimes he does do silly things… and Rainbow Dash and Pinkie Pie have a bad habit of encouraging him now that they’ve warmed up to him. They like pranking ponies too, and Pinkie takes any opportunity she can find to get him to make chocolate rain…”

“Uuuugh,” Apple Bloom groaned and rolled her eyes. “Okay, fine, he got me, Ah went an’ embarrassed mahself in front of the whole class, now tell him ta put me back ta normal!”

Fluttershy blushed and hung her head slightly. “Um… I’m sorry, but… I can’t.”

“What?!” Apple Bloom exclaimed. “Why not?!”

“W-well, normally I would, but… unfortunately, he’s… not here right now. In Ponyville, I mean.”

“Not in Ponyville?! But he was just here yesterday! Where the hay else would he be?!”

“He left just this morning for Canterlot…” Fluttershy admitted with a truly sympathetic sigh. “He said he was going to help the princesses with something, and that he’d be gone for a couple of days…”

Apple Bloom’s eye twitched. “D-days?!”

“I’m sorry…” Fluttershy said again. “I’m sure it was something important…”

“Yeah right, he was probably just trying to hide and laugh at me!”

“Well… I suppose that might be true, and if it is, I’ll talk to him about lying on top of pranking, but either way, I’m afraid there’s nothing I can do until he turns up again…”

Horror filled Apple Bloom’s expression. “So Ah’m stuck like this?!”

Fluttershy gulped. “Um… from the looks of it… I’m afraid so, yes… f-for a little while, anyway… I’m very sorry…”

Apple Bloom’s head drooped low to the ground, and her heart sunk all the way down to the bottom of her hooves. It was official, her life was over. Even if her appearance at school could somehow have been explained away as some kind of joke or magical illusion, and that was certainly no guarantee… there was no chance of it now. The story was going to spread. Everypony was going to know what happened to her. Applejack was going to know what happened, and as soon as she did Apple Bloom would be grounded until the next school year. And that was just at home. She’d be a total laughingstock at school. Diamond Tiara alone would be insufferable, but now the whole school would be laughing at her. Even her friends had been unable to do anything but stare at her.

Fluttershy laid a comforting hoof on her shoulder, seeming to read her dejected and miserable expression like a book. “Oh, don’t let it get you down, Apple Bloom… I’m sure being a boy isn’t so bad… most colts and stallions I know certainly don’t complain about being boys.”

“But Ah’m not a boy, Ah’m a filly!”

“I know… but try to look at the positives,” Fluttershy urged her. “It’ll only be for a couple of days, Discord can’t hide forever… and, well, really, you have a rare opportunity here… you can see how it feels to be the other gender. Nopony’s ever really gotten to do that before, as far as I know…”

“Well… yeah, Ah guess, but…”

“A-and at the very least, well, you get to spend a few days in the peak of mating season… not having estrus. A-a lot of mares would be really jealous of that… I know I am…”

Apple Bloom couldn’t help perking up slightly at that. As awful as everything else seemed, that was a really pleasant silver lining. Not dealing with estrus for a while, especially in the midst of all this other junk, was truly a gift from the goddesses. That would have been awful. And frankly she wouldn’t have put it past Discord to pull that on her anyway. She was certain it was within his power to do. But fortunately she seemed perfectly in control of her loins as a colt. The only thing they had to worry about was probably being out in public and getting an erection at the sight of a pretty mare. That sounded like a challenge all its own though, especially with mares as pretty as Fluttershy around and wanting to find somepony to--

A bright blush hit Apple Bloom’s cheeks.

Suddenly she really needed to be somewhere else. Anywhere else.

“W-well, uh, t-thanks for l-lettin’ me know what’s goin’ on, Fluttershy, but Ah gotta run!” Apple Bloom stammered out, turning to hurry away.

“O-oh, alright… I-I’ll keep an eye out for Discord and make sure to talk to him first chance I get… good luck, Apple Bloom!” Fluttershy called after her.

“Thanks!” she called back, picking up her pace and hurrying back to Sweet Apple Acres. She didn’t want to skip school, but there was no way she would be going back there like this, not right away, and especially not now that she was walking with a new, awkward sort of limp, courtesy of the strange and foreign appendage she could now feel dangling between her legs and brushing against her thighs.

For better or worse, she had a pretty good idea what it was.

In another minute or two she was back on Apple family property, hurrying through one of the more private and secluded acres and at last setting eyes on the sanctuary of her clubhouse, once built into an especially thick and sturdy apple tree by Applejack and later remodeled by Apple Bloom herself into the headquarters of the Cutie Mark Crusaders. She made her way up the ramp and inside the little house, shutting the door behind her and tossing her saddlebag to the floor before flopping back on her butt on a cushion in one corner of the room. She leaned back against the wall corner and stared at the ceiling, trying to pretend she couldn’t feel the lump of flesh between her legs and that it wasn’t making her freak out a little, but it was no use. Even if she hadn’t felt it growing and tingling at the thought of a pretty mare, she couldn’t not notice it anymore. Something was there now that wasn’t before. And she couldn’t ignore it forever.

Gulping down a heavy breath, Apple Bloom chomped the bit and dipped her head to take a look between her hind legs.

A long, long look that left her blushing to the tips of her ears.

Welp. It was official.

She had a penis now.

Sitting back on her butt against the wall as she was, the new appendage was sort of dangling half-erect out over the floor, just aroused enough to come out of its sheath but not quite enough to perk up like a flag pole. It looked to be a pretty normal size; not that she had much to compare it to, of course, but sex-ed class had certainly made note of average sizes for both male and female parts, and this one seemed about in line with that. Maybe a bit bigger, she guessed, on account of her slight increase in overall body size. That stuff was usually pretty proportional. Her hoof reached for the appendage, gingerly lifting and pulling it away from the floorboards as if afraid she’d get a splinter, and let it lay across her own chest instead where she could get a better look at it.

“W-wow…” she whispered.

The shaft of her new equipment tingled a bit where she touched it, but she was too busy taking in the sight to worry about that just yet. Much like the one she’d seen on Rumble, hers was a bright, fleshy pink around the nearly flat and slightly fatter tip, and down most of the upper half of the shaft. And as she glanced down the length of it, the colors became mottled around the medial ring, transitioning away from pale pink until it matched her own coat color closer to the base of the shaft, as if her natural pigment seeped right into the flesh. Just below that was her new pair of testes, which appeared to be rather generously-sized to Apple Bloom’s admittedly limited knowledge and experience, the protective pouch of skin there also shaded the same color as her coat.

“Okay now… don’t freak out…” she told herself out loud. “It’s just a… a-a penis… all boys got one… it’s totally normal… other’n the part where Ah’m a filly an’ Ah should have filly parts…”

She reached down suddenly at that thought, feeling around underneath her sack for a moment, but there were most definitely not any filly parts there any longer. All she really managed to do was whack her testicles with her hoof a bit too hard in her haste, making her gasp and wince in a sudden, sharp pain. Spike really hadn’t been kidding yesterday, those things were sensitive, and not in a good way. She’d have to be super careful about that from now on.

Her hooves rested instead on the shaft of her new penis, carefully getting a feel for the strange and foreign organ. It felt a little weird doing so; it was of course technically hers, and there was really nothing wrong with exploring one’s own body, but still… it was brand new to her, unfamiliar, not at all the parts she was used to having, and in a lot of ways it felt like it wasn’t her own body she was exploring, but another colt’s, putting her hooves all over somepony that wasn’t herself, touching his penis, feeling it, getting aroused by it…

Apple Bloom gulped down a soft gasp, feeling the penis growing harder and more fully erect and blushing in deep, surprised arousal at the sight, which only seemed to make it harder. Wonderful, she was getting hard from watching herself get hard. That wasn’t weird or narcissistic or anything. But she couldn’t exactly help it; it really did feel like she was watching some other colt’s dick get all stiff and excited, and she hadn’t exactly stopped being excited by boys and their dicks just because she was one herself now. Except thinking about pretty mares was what had gotten the erection started in the first place, and her own memories of playing with herself the other day were suddenly much more appealing to recall and made her newly-hard dick twitch in building excitement.

Without really even consciously thinking about it, her front hooves curled gently around the shaft of her new colthood, sort of hugging it between them. The tingling arousal she was feeling grew stronger at the touch, until she was reasonably certain it was about as hard and erect as it was going to get. It looked bigger than before, all swollen and stiff. Certainly bigger than the last one she’d seen. It was at least a full foot long now, and big enough around that she wondered if it could even fit inside a filly the way it was supposed to.

Apple Bloom’s blush immediately grew stronger, and so did her arousal levels. Goddess above, was she really thinking about… doing that? About getting into bed with another filly while she was still stuck as a colt, climbing onto her back or laying her down and spreading her legs, and sticking this hard, twitching dick inside her? About holding some filly gently in her hooves and kissing her as she rocked her hips and pushed that dick in and out of her, over and over, in and out--

“Unnhh…” Apple Bloom let out a deep, low groan, feeling another jump of desire as she realized her hooves were actually moving now, stroking her dick between them in a slow and steady, up and down rhythm just as she’d been imagining. The feeling was incredible; pleasure was shooting through her body at every slight touch and rub, like she was stroking one big clit. Her mind had no trouble conjuring up helpful images now, and although her usual stand-bys of cute boys like Spike and Rumble and their wonderfully talented dicks still made her squirm in happy satisfaction, now she suddenly found herself much more amicable to picturing girls too, cute fillies and beautiful mares dancing through her thoughts like a parade.

There were so many of them to imagine, too. For a moment she wasn’t sure which filly she wanted to picture underneath her. It was the exact opposite problem from what she’d had as a filly; instead of no good colts to choose from, there were so many girls that she couldn’t settle on just one. Fluttershy had said she wished she didn’t have estrus… oh yes, Fluttershy was very beautiful, just the thought of getting a glimpse under her tail, let alone doing anything under there, made her body shudder and twitch, and especially her increasingly sensitive and excited erection. Or perhaps… Miss Cheerilee… ooh, that was dirty, filthy, Apple Bloom felt guilty for even thinking it, and yet it sounded so incredibly exciting to explore just what that whole ‘hot for teacher’ fantasy was about. Maybe her old friend Twist, with her big cute glasses and wild curls… or maybe the mailmare’s daughter, the cute unicorn filly in the Rainbow Dash fan club… or… or…

Oh, there were so many… and it felt so good, no matter who she thought of. Her hooves were pumping up and down the length of her shaft much faster now, making her moan and groan deep in her throat at the sheer satisfaction. At some point she’d started leaking some kind of thick fluid from the tip of the thing, a little sticky but at the same time very slick, just like the juices she used to get coated with when she got worked up as a female, and now it was smeared all over her hooves and her dick, lubricating both and letting her work herself that much faster. She could scarcely stand it, the pleasure was insane, and so much easier to achieve now. Goddess, what would Sweetie Belle and Scootaloo think of her if they saw her now, sitting here rubbing her big twitching colthood…

Apple Bloom’s blush grew stronger than ever. Goddess, what would they think? Would they be disgusted? No, they were her friends… her best friends, she adored them both, they wouldn’t be disgusted… they’d be supportive… maybe very supportive… maybe even help her out a little… yes, that’s what they would do, Apple Bloom decided, losing herself in fantasy completely. Sweetie Belle and Scootaloo would love to help out… it was their hooves on her dick rubbing her now, one from each of them, making her feel oh-so-good, because that’s what friends did for each other… and Apple Bloom would help them too, of course. They were still fillies after all, still suffering from heat season… she didn’t want to be the only one lucky enough to escape it, she would have done anything to help relieve them of it too. Except now she had the means to do so… she could help them…

With another deep and heated gasp she imagined them, the both of them, laid back before her, legs spread wide, making Apple Bloom blush and grin and jerk herself even faster. She’d seen them down there before, of course, they all had seen each other before, in passing at the very least, but quite explicitly that one curious afternoon after sex-ed classes when they’d spent far too long talking about all the exciting grown-up stuff they’d just learned. They’d even shared their self-pleasure methods with each other after a three-way spit-swear never to tell another living soul. And that was how she imagined them now, splayed out before her and attacking themselves in desperation. Sweetie Belle had really sensitive nipples and almost spent more time playing with her teats than her pussy to get off, but Scootaloo went right for the clit and nothing else, rubbing it for as long as she could stand without getting overwhelmed and resting an absolute minimum before rubbing it again. But Apple Bloom knew all too well that it wasn’t going to be enough, not in estrus season, and now they were asking her, no, begging her to help them quell their estrus, spreading their soaked pussies and--

It was too much. Several tons too much. Apple Bloom clenched her eyes shut and let out a deep, guttural groan as she completely lost control, succumbing to the new frontrunner for “Best Orgasm Ever.” Pleasure and relief and satisfaction flooded her senses and filled her with an incredible warmth, and the pressure that had been building in her hips suddenly found its release and surged up the length of her now-flared cock, her hooves still flying up and down the whole of it. She forced one eye open to take a peek at herself, just in time to see the first huge pulse of thick, off-white boy-cum explode out of the tip and draw a line from her belly all the way up her chest. She gasped in awe just in time for the second shot to sail through the air and paint another streak of semen up her neck and chin and even a bit right into her open mouth. Instantly she snapped her jaws and eyes shut again in shock right as her cock fired the third and fourth and fifth bursts, hitting her full-on in the face and splattering her cheeks and muzzle and forehead with the hot, sticky goo. The next couple of shots were weaker, slowly squirting out of her tip more than outright firing, and falling to join the first one on her chest. One last dribble leaked out and left a small splotch of white on her belly, and then it was over as quickly as it had begun, her hooves at last coming to a stop, her body slumping lower against the wall, and her pleased new appendage finally relaxing and gradually receding back down into its sheath.

“Mmmhh… holy horseapples…” Apple Bloom murmured as she heaved a deep, happy sigh. She was a complete mess, covered in her own expulsions, but she had never felt better in her life. The actual orgasm hadn’t lasted as long as she was used to as a filly, but that had been easily made up for with sheer intensity. And better yet, the relief and satisfaction still running through her were so strong she almost felt like she could pass out for a nap. It was a far cry from her experience yesterday, when self-pleasure had only made things worse. Boys had it so easy this time of year… or any time of year they felt like enjoying themselves, really. Stroking a penis was so much simpler than trying to satisfy a vagina that wanted something inside it when she didn’t have anything smaller than a big honking hoof. Maybe this time spent as a boy wouldn’t actually be so bad…

…Although maybe in the future she’d try to be more careful about where she relieved herself. She was in dire need of a washrag now.

With a groan she sat up a bit straighter and slowly blinked her eyes open, which were thankfully clear and untouched by the mess she’d made of herself. She blinked a few times to focus her gaze--

And then froze.

Scootaloo was standing directly in front of her, her eyes and her wings as wide-open as they’d been back at school, her cheeks a bright, radiant pink.

And she was staring directly at Apple Bloom.

“…Uh.” Apple Bloom gulped and forced a smile, trying not to freak out or look too guilty about the fact that she’d basically (literally) just jerked off thinking about the filly in front of her. “Hi… Scootaloo…”

“…Hey… Apple Bloom…” Scootaloo swallowed hard too, and her throat sounded dry as she spoke. “M-Miss Cheerilee… sent me to… find you… we were, uh…worried…”

Her voice shook as she spoke, and Apple Bloom couldn’t help notice her eyes were darting rapidly back and forth between Apple Bloom’s face and her crotch. How much had she seen? Apple Bloom hadn’t even heard her come in, it could have been at any time…not that it mattered, any amount of time was too much, and she’d almost certainly seen the big finish, and the evidence of it was all over her face…

“Can you… make it come out again?”

Apple Bloom nearly jumped out of her skin. “W-what?! M-make what come out?” she asked, though she was pretty sure she knew.

“That…” Scootaloo pointed at her sheath, confirming Apple Bloom’s suspicions. “Can you make it… come out again?”

Whether she wanted to or not became swiftly irrelevant. The mere thought of Scootaloo wanting to take a good look at her new equipment was all the encouragement it needed to reverse course, come back out and say hi.

“Oh wow…” Scootaloo whispered, stepping closer and staring unblinkingly as her penis slowly grew back to full extension. “You really are a boy…”

“A-Ah am not!” Apple Bloom insisted. “A-Ah just… got turned inta one… i-it’s a long story…”

Scootaloo didn’t seem especially interested in hearing said story at the moment, though. She was moving closer and closer, her hindquarters shaking with each step, and her gaze was slowly drifting up Apple Bloom’s body to focus on her face. “Can you…” she started, hesitating for the briefest of moments. “…Can you make that come out again too?”

Scootaloo pointed at her face this time, and Apple Bloom went as red as the ripest fruit in the orchard. “W-w-wh… what’re ya talkin’ about?” she stammered, though again, she had an incredibly good idea.

“Y-you know… that… stuff,” Scootaloo said again, blushing just as hard and pointing more directly at the stain on her cheek, again proving Apple Bloom right. “That comes out when a colt has an orgasm… s-semen, or whatever it’s called… t-the stuff that makes estrus go away…”

Scootaloo reared up suddenly and planted her front hooves on the wall, on either side of the other filly’s head. Apple Bloom’s eyes widened, suddenly afforded a much clearer look at Scootaloo’s lower half, and even standing stock still her hips were shaking, quivering even. The fur on the insides of her thighs was matted down with a familiar-smelling liquid, and there was an intense, damp heat just above Apple Bloom’s back legs. Even if Scootaloo hadn’t just brought it up, there was no mistaking those signs; Apple Bloom knew them all too well.

“Holy ponyfeathers, Scootaloo…” she gasped, a wave of sympathy rushing through her to join her arousal. “Ah thought ya didn’t ever feel estrus that bad…”

“I told you before, I do too!” Scootaloo shot back. “I just don’t make a big deal out of it… doesn’t mean I don’t hate it as much as every other filly…”

Apple Bloom blushed and nodded vehemently. “Ah know, it sucks, Ah had a real bad day of it yesterday too…”

Scootaloo moved even closer, until she was almost fully upright, hovering over Apple Bloom’s body with that damp heat poised directly over her waist. “But you’re… you’re a boy now, right?” she murmured, staring down at the telltale dick. “You’ve got… you can…”

Apple Bloom nearly lost it again right then and there. Scootaloo’s hips were moving lower, like she was trying to sit in her lap, and the tip of her freshly-hard-again shaft was mere inches from getting in the way of that, pointing right at Scootaloo’s clearly-drenched fillyhood. The heat she felt was incredible, especially with her sensitive erection so very close to the source. If Scootaloo lowered another couple of inches…

“Can… can we? Please?” Scootaloo almost begged. “We’re friends, right? I can’t take this anymore, and you can help, Apple Bloom, you can make it go away, you gotta help me, please…”

Scootaloo shifted even closer. They were less than an inch apart now, and Apple Bloom could literally feel droplets of Scootaloo’s aroused juices dripping right onto the tip of her dick. But even that didn’t make her shudder as hard as Scootaloo’s actual words. Not even five minutes after she’d fantasized about nearly this exact scenario all the way to orgasm, here it was happening for real; Scootaloo, one of her best friends in the whole world, pleading for her to put her new dick to use, to put an end to the hormone cocktail that on any other day she would be too proud to admit was crippling her. And she really could do it, too; she could help Scootaloo. Everything seemed to work the way it was supposed to for a boy, as far as she could tell. Scootaloo was miserable, and Apple Bloom had the power to put an end to it.

Yes. She could do it.

She could have sex with her best friend.

“S-Scootaloo…” Apple Bloom gulped heavily, staring at the point where their bodies were about to meet. “A-are ya… are ya sure about this?”

“Yes!” Scootaloo insisted, moving lower still, and whimpering outright as Apple Bloom’s dick just barely brushed her outer lips. “Yes I’m sure! Please, Apple Bloom!”

“W-well… o-okay… i-if yer sure, then… okay, y-yeaAAAHH!!!”

Apple Bloom let out a shocked yelp as she felt a sudden intense heat and wetness engulf the entire length of her member. Scootaloo’s hips had dropped all at once the moment she’d gotten the go-ahead and impaled herself on Apple Bloom’s dick in one swift motion, apparently not wanting to wait even a second longer than absolutely necessary. Her hips landed in Apple Bloom’s lap with a wet smack, and she howled in some primal mix of pain and pleasure, her whole body shaking now.

Apple Bloom was barely aware of her though, because her own body was also wracked with truly mind-boggling levels of pleasure. However incredible playing with herself had felt, it was nothing compared to the depths of Scootaloo’s pussy, absolutely nothing. It was warm. It was wet. It was throttling her dick from base to tip, hugging and squeezing the sensitive flesh tighter than a cinched lasso. And it was absolutely wonderful.

“Oh wow…” Apple Bloom groaned. “Scootaloo… Ah had no idea… sex felt this good…”

Scootaloo whimpered something unintelligible, her front hooves still braced against the wall on either side of Apple Bloom’s head. Her muzzle was turned down and her eyes were closed as she gasped for breath, looking more overwhelmed than even Apple Bloom herself felt.

“S-Scootaloo? Y’alright?” she asked, prodding her friend gently in the cheek.

Scootaloo lifted her head with a grunt, giving Apple Bloom a slightly shaky smile. “I’m great… I’m really… really great… I feel better already…”

“Oh… heh, good…” Apple Bloom returned the smile, trembling herself in awe. “Wow… we’re… we’re actually… doin’ it…”

“Sure are…” Scootaloo agreed. “Mnnhh, holy Celestia, you weren’t kidding… it kinda hurt at first, but now… wow… it feels way better than doing it by myself…”

Apple Bloom nodded in vehement agreement, her front hooves finding Scootaloo’s hips and taking hold. “S-Scootaloo… should Ah… ya know… start?”

“Oh hay yeah…” Scootaloo answered, nodding frantically. “H-here, lemme help…”

Scootaloo moved her front hooves down to brace them on Apple Bloom’s shoulders, and shifted her back legs until she was on her knees, coiled like a spring ready to bounce. And a second later ‘bounce’ was exactly what she did, gripping Apple Bloom’s shoulders tighter and pushing off with her back legs. She slid all the way up Apple Bloom’s shaft, until it was more than three-quarters out of her again and made Apple Bloom shiver a bit at the feeling of cool air against the length of her dick, coated now in Scootaloo’s plentiful juices. And then just as the teenage Pegasus’ legs reached nearly full extension, they fell limp again, driving the entirety of Apple Bloom’s cock back inside her and making both of them cry out in sheer, shocked ecstasy. Her legs coiled again to repeat the motion, and this time Apple Bloom helped her, tightening her grip on Scootaloo’s hips and lifting her up at the same time, and relaxing when Scootaloo did, letting her drop and meet her hips with another juicy slap. Together they repeated the motion several times, finding a comfortable balance and rhythm, and soon they were sharing the exertion about evenly, thrusting against each other at a calm, steady pace that had both ponies gasping for breath after pleasured breath.

“Oh my Celestia, yes…” Scootaloo whimpered. “This is freaking amazing, Apple Bloom, holy ponyfeathers…”

“Yer tellin’ me…” Apple Bloom groaned back. “And Ah thought just doin’ mahself felt good…”

“Yeah, I noticed…” Scootaloo agreed with a breathless snicker, pausing their thrusting for a moment and leaning closer to poke a hoof against her cheek. “Made a real mess of yourself in the process…”

Apple Bloom flushed a bit as Scootaloo’s hoof pulled back with a sizeable glob of cum stuck to it, one of many that were still decorating her face. Apple Bloom thought it felt a little weird and slimy, and smelled even weirder, if she was being honest, kind of musky and sweaty. Scootaloo however seemed to be having an entirely different reaction, as though it was just one more thing about Apple Bloom’s new male-ness that was instinctively turning her on. She blushed even deeper than she already was as she brought the little sample of male essence close to her muzzle, taking a curious sniff and then, to Apple Bloom’s immense shock, outright licked her hoof clean.

“Eewww, Scootaloo!” Apple Bloom blurted out, flushing. “That… that’s…”

“Not that bad, actually,” Scootaloo finished for her, glowing brighter still. “Kinda exciting, really…”

Apple Bloom had no idea what to even say to that, her brain was so fried with disbelief, but she wasn’t one to stop Scootaloo from doing something she enjoyed. So when she leaned in even closer than before, Apple Bloom simply sat there and stared in awe as Scootaloo brought her muzzle right up to Apple Bloom’s cheek, stuck out her tongue, and licked all the way up the side of her face, taking every trace of cum she touched with her. Apple Bloom shuddered with arousal as Scootaloo repeated the motion on her other cheek, and then up her chin, and then across the bridge of her nose, and even over her forehead before starting it all over again, covering every spot where Apple Bloom had managed to cum on herself. By the time she finished the second pass Apple Bloom’s face was clean as a whistle, and when Scootaloo at last leaned back again, grinning and blushing like a fool, she tilted her head back and swallowed her mouthful, cum and all, in two loud, obscene gulps.

“Heh, see?” Scootaloo insisted. “It’s not bad at all. I’ve tasted way worse…”

Apple Bloom wasn’t listening though, because her cock was twitching and throbbing more excitedly than ever after Scootaloo’s display, and there were very few thoughts left in her brain that didn’t relate to the fact that she was very horny, and she really needed to cum again. She took a firm hold on Scootaloo’s hips again, and with much more insistence this time around she resumed their earlier motions, lifting her up entirely by her own strength and slamming her back down onto the stiff, soaked cock between them.

“AAHHH!” Scootaloo cried out, loosing track of whatever she had been saying. “O-oh, buck, Apple Bloom…”

“Shut up an’ help me finish…” she grunted back.

“Y-yeah… you got it…”

Scootaloo let her forehead rest against Apple Bloom’s and swiftly resumed her share of the work, legs pushing off as Apple Bloom lifted her by her butt and dropping onto her lap again with a satisfying squish every time she relaxed. Their pace was faster now, less consistent and more frantic, both knowing what was coming just around the corner. Scootaloo was completely drenched by this point, and by proxy so was Apple Bloom, their lower bodies a mess of matted fur and sweat and girl-cum that was only getting messier. And despite that making it slightly easier for Apple Bloom to push her way back into Scootaloo’s pussy at first, her internal walls were squeezing her much harder now, desperate to keep hold of the thrusting totem of male virility ramming its way into her and making it that much more difficult overall to split Scootaloo open. Apple Bloom could feel the head of her cock flaring too as she neared the edge, making Scootaloo’s pussy feel that much tighter right where it mattered most and forcing her to work extra hard for those all-important final thrusts.

“Scootaloo…” Apple Bloom gasped out, opening eyes she hadn’t even realized she’d closed and looking up at her friend. “Ah’m almost there again! Are ya… absolutely sure--”

“Yes!” Scootaloo hissed right back at her. “Yes I’m absolutely sure, don’t stop now Apple Bloom, don’t you dare stop now!”

Apple Bloom gave her what few more thrusts she could manage, but she had at last reached her threshold again, the thought of holding back nowhere to be found. Her hooves left Scootaloo’s hips on the final up-thrust, wrapping instead around her midsection just beneath her tiny, outstretched wings, and just as Scootaloo’s legs fully extended and went limp again, Apple Bloom kicked them out from under her and let the Pegasus’ full weight land unchecked on her twitching cock.

“AAAAAAAAHHHHHHHH!!!!!!!!”

Apple Bloom didn’t really know or care which of them had screamed. She was as far inside as she could possibly go now, pressing into the absolute depths of Scootaloo’s pulsing, clenching pussy and holding there, and the sensation was more than enough to send both fillies to their mutual orgasms. Scootaloo screamed her name, twitching and bucking and cumming her guts out, and Apple Bloom was doing the same, holding tight around Scootaloo’s waist and bellowing her friend’s name into her neck and shoulder as her cock shuddered and convulsed. A second later there was a splash of warmth on her lap as Scootaloo released a small torrent of filly-cum just about everywhere, and Apple Bloom’s cock responded in kind, spitting volley after volley of fluids right back into her and coating the back of her pussy with every bit of semen she could muster.

The effect was nigh-instantaneous. Scootaloo’s shrieks of pleasure skyrocketed in volume as soon as the first blast of cum splattered inside her, as though it were a soothing balm on a nasty burn. Then another puddle joined it, and another, and another, every burst of warm seed that cascaded out of that throbbing, pulsing cock becoming another cry of relief that escaped Scootaloo’s throat, filling her and filling her and filling her until Apple Bloom just had nothing left to give. It was enough though, she was certain, and only became moreso when the two exhausted fillies flopped to the floor and pulled apart, and Apple Bloom saw that Scootaloo was stuffed so full of her load that cum was actually trickling out of her, now that she wasn’t stuffed full of cock too. If that hadn’t been enough to quell a bad case of estrus, nothing would be.

“W-well… S-Scootaloo?” Apple Bloom managed to say between gasping breaths, her erection at last relaxing and receding for good. “How… how do ya feel?”

“Like a million freaking bits,” Scootaloo answered with a tired grin. “I am never gonna waste my time on tea and ice packs again…”

“Really?” Apple Bloom brightened. “So it really worked, then? Yer estrus is gone?”

“Out like a light,” Scootaloo confirmed. “I haven’t felt this good since I figured out what a clit was…”

Apple Bloom’s eyes widened a bit again. “Wow, that good?”

Scootaloo nodded back. “Yeah. That good. You were freaking awesome, Apple Bloom.”

“Aww, shucks… Ah was just goin’ on instinct, Ah didn’ know what Ah was doin’,” Apple Bloom answered, blushing modestly.

“Hey, you did great,” Scootaloo insisted again, rolling up beside her and hugging her. “Seriously, I… I dunno how I can thank you enough.”

Apple Bloom hugged her back tightly. “Ya don’t gotta thank me, Scoot, yer one o’ mah best friends, if there was anything Ah could do ta help ya, ‘specially with estrus, a’course Ah’d do it…”

“Still…” Scootaloo murmured, a small blush reappearing on her cheeks. “Thank you. Really. It means a lot to me.”

In the blink of an eye Scootaloo’s head swept inward, and planted the smallest of kisses on Apple Bloom’s lips. It lasted only a second, but it created an exciting and electric tingle on her lips nonetheless, warm and wet and full of honest affection that Scootaloo rarely showed outright and left a surprised splash of crimson on Apple Bloom’s cheeks.

And then the second passed, and the sentiment was gone with Scootaloo’s lips. “If you ever tell anypony about that, I’m gonna buck you in the balls,” she warned. “Clear?”

Apple Bloom reflexively winced and crossed her hind hooves. “Heh-heh… crystal.”

“Good,” she said, standing up on wobbly legs and tucking her tail tightly down over her backside. “Anyway, we better go clean up… and then you are gonna explain to me how in freaking Tartarus you’re suddenly a boy.”

Apple Bloom heaved a weak sigh. “Like Ah said, it’s a long story…”
