1 - Missed Connections

Twilight knocked on the door to Fluttershy’s cabin. “Fluttershy? Are you okay?” Of course Twilight was worried. Their plans for today had been set in stone for almost two weeks, or so Twilight had assumed. But here she was, almost an hour after they were supposed to meet up at the cafe, and no sign of Fluttershy. The only possibility that Twilight could think of was that something was wrong. And it had to be something big and sudden, or else Fluttershy would have told her somehow. There had to be some reason she didn't show up. She knocked again.

There was a shuffling sound inside the cabin, followed by a small commotion, and then the door opened a crack – only a crack. Twilight caught a glimpse of a blue-green eye and a sliver of yellow and pink and nothing else, not even the interior of Fluttershy's home. “Oh. Hello Twilight. I, um. Think I'm going to have to cancel our plans today. Sorry.” Fluttershy's voice was quieter, even moreso than usual, and had a rough, throaty quality to it, like she had a very bad cold.

“What? Why?” Fluttershy sounded sick, yes, but if it was just a cold, surely she'd have at least ventured out to let Twilight know, or at least sent Angel Bunny with a note. No, it had to be something more than that.

“Something came up.”

“Fluttershy, what's wrong.” It wasn't really a question, not the way Twilight said it.

“Something, um. Personal.” Fluttershy groaned, deep and throaty and much louder than was characteristic of her. “Very personal.”

“Are you sick? I've been reading up on common diseases and I think I can probably give you a hand if you'd just let me-” She grabbed the door and pulled, only to find herself stopped by a chain lock.

“Um. Sorry. I'll be fine. It's just a personal thing.”

Though Twilight couldn't actually get into Fluttershy's home, she could get a better look. Everything seemed in order, if a bit cluttered. But Fluttershy's home was always somewhat cluttered. But Fluttershy was a different story. More of her was visible with the door more open, but not much, especially considering the fact that she seemed to have shuffled her way to being mostly hidden behind the doorway. There was just enough of her visible to confirm that something was off. Her hair was dishevelled and wild, and her fur was almost soaked with sweat. She was wearing a bathrobe, clearly hastily thrown on as it was barely closed over her substantial breasts (or at least her right breast, which was the only one visible from Twilight's perspective.) A good third of her nipple was visible, bringing a slight blush to her face. But that was hardly the main reason for Twilight's blush. No, what really stood out was the smell.

The overpowering stench of sex oozed from Fluttershy's home.

“Sorry,” Fluttershy muttered, followed by another throaty groan that it dawned on Twilight was actually very much a moan.

“Oh. Personal. Right, heat. Sorry, I probably should have known.”

“Yes. Something like that. Sorry. Um, we can maybe try again next week? Sorry.”

“Right. Next week is fine. See you then.” Twilight forcefully shut the door, turned around and awkwardly marched off. Fluttershy let out a sigh of relief that very quickly turned into another moan. “Gnh. Took her long enough.” She took a step back from the door, letting the bathrobe drop and removing her other hand from her crotch. And not a moment too soon – there was absolutely no way that she could have held her three foot long, throbbing horsecock out of sight any longer. She glared down at her head, leaking a steady stream of thick, glistening precum inches from her face. “I swear, you pick the worst times to go into rut on purpose. What do you have against me having a social life?” she muttered at the beast through tightly clenched teeth, her head-sized breasts heaving with the effort of holding back her orgasm. “And of course she comes right as I'm in the middle of masturbating. Half an hour earlier, Twilight, really. Your timing couldn't be worse.” The flow of precum increased to a torrent, gushing from her urethra. And then she finally let go.

Her orgasm lasted twenty four minutes.

Author's Note

Fluttershy cannot hide her gargantuan boner and it's making her social life even harder to deal with.

Not too happy with that ending there, but all in all I think it turned out okay.

2 - Blind Date

“So, um... What do you do for a living?”

“I break rocks.”

“Oh.”

In retrospect, letting Pinkie Pie set him up on a blind date with her “hot sister” (her words, not his) had not been Caramel's brightest decision ever.

“With my penis.”

“Ah.”

He swallowed heavily. “And, um, do you always go around not wearing, you know, clothing?”

“Yes.”

“Ah.”

All available avenues of smalltalk exhausted (Caramel was not good at smalltalk), he stared in awkward silence at his drink, his meal, and basically anything other than Maud. She wasn't unattractive, really, besides the penis. The very large penis.

The very erect penis.

“It's because of my penis.”

“Hm?”

“I don't wear clothes because of my penis.”

“Oh.” Caramel stared intently at his glass.

“It doesn't go down.”

A drop of precum oozed from her head.

“I see.”

“So it makes clothing hard to wear. So I don't.”

Her penis twitched slightly and another bead of milky white fluid leaked from her urethra.

“Okay.” He turned his gaze to his plate. He could have sworn there was more food there. He certainly didn't remember really touching his meal, and yet there in front of his eyes was solid evidence that he was almost done. He wasn't quite sure whether or not that was a good thing. As far as he was aware, this was just a casual date that Pinkie Pie had set up because Maud was lonely (presumably because of the penis thing, he assumed), so hopefully she wouldn't expect anything more than a friendly goodbye. Hopefully.

He tried very hard not to look at her penis but he found that he had ran out of things to stare at that weren't her penis so he found himself staring at her breasts instead. They were fairly large; on a mare without a three foot penis, they would have been impressive, each one slightly smaller than her head.

But the penis kind of stole the show.

He forced his eyes up to make contact with hers. She was staring, unblinking, at him. “So, um. It doesn't go down? Ever?”

“No. Not since puberty.”

“That sounds, um, inconvenient.”

Maud shrugged. “It's not too bad. There's more inconvenient things than the erection.”

“Oh?”

“Well, sometimes it – hold on.” She closed her eyes tightly and bit her lip. “Do you have a towel?”

“What? Why would you need a-” Caramel's train of thought was interrupted by a very loud, liquidy gurgle noise that came from Maud's direction. “Um.”

“Too late. Get under the table.”

“But-”

“Now.” Maud's voice was uncharacteristically loud and intense. With that tone of voice, Caramel didn't need to be told more than once. He dove under the table, and found himself face-to-face with Maud's balls.

They were also large. Everything about her was large. Certainly larger than Caramel. He had never been particularly good at estimating heights, but he knew that he was five feet even, and that Maud was at least a head and a half taller than him, which would make her about 6'5”, emphasized by her impressive musculature.

Her balls contracted and her hands tightly grasped her seat as Caramel realized that he probably had higher priorities than philosophizing about Maud's largeness.

She let out a deep, primal moan that steadily got louder and louder as her hips convulsed wildly, her arms shook, her cock throbbed and her testicles pulsated inches from his face.

Caramel could swear that with each pulse the distance between his nose and her balls got smaller and smaller. In fact, he was certain that they were very slowly getting larger and larger, and her shaft was almost definitely pulsing thicker and thicker and (presumably, although it was a bit hard to tell from under the table) longer and longer with each passing second of orgasm.

His nose was filled with the scent of sex and musk as her testicles slowly shoved themselves into his face.

He tried his very hardest not to lick them. Perhaps Maud expecting more than a friendly goodbye wouldn't be such a bad thing after all, although that was probably the pheromones talking.

Eventually, after an impressively long time, Maud's orgasm slowed down and then came to an end. She pushed her chair back, and awkwardly shoved her now person sized cock aside so that she could lean down under the table and talk to Caramel. “Sometimes it spontaneously orgasms. Also sometimes it gets much bigger.” She blushed slightly, although it was somewhat hard to tell under the thick coating of translucent fluid that coated her entire upper body. “Are you okay? My balls aren't crowding you too much under there, are they?”

“No, I'm fine.” Considering how huge her cock had gotten, he felt that he had gotten lucky that her balls only reached about half again the size of his head before stopping their growth.

“It should go back to normal after only ten orgasms or so. Although, um.” Her blush intensified. “I'll need some help getting home.”

“That's fine.”

“And getting through doors.”

“That's fine.

“And getting off when I get home.”

“That's fine.” Caramel's voice squeaked on the last fine.

Maud licked her lips, removing a small amount of cum from her face before lifting a hand to her chest and scraping a huge glob of cum off of her right breast with an index finger. “Would you like a taste?”

Caramel fainted.

Author's Note

Maud has trouble getting a date because she shatters rocks with her dick for a living.

this one was super fun to write. Awkward Loser Caramel makes for a fantastic porn protagonist and I definitely want to write more about him getting stuck in awkward situations centered around my various weird fetishes.

3 - Ordering In

“Okay, so five extra large mushroom and hay pizzas with mozzarella, parmesan, and cheddar with extra everything and a stuffed crust. That'll be 1600 bits.”

“Aren't you a Wonderbolt?”

Lightning Dust winced. Sore subject had been thoroughly found and hit. “And aren't you a bit to literally fucking royalty to be ordering five pizzas?” is what she wanted to say, but didn't because that would probably get her fired. Instead she just glared at the customer. “1600 bits, ma'am,” is what she said instead.

Twilight's gaze narrowed. “No, I'm certain that I saw you at the Wonderbolts' Academy. Lightning Dust, right?”

Lightning Dust suppressed a frown, instead just averting her gaze and blushing. “Why, yes, I was in the Wonderbolts Academy, until your stupid traitor friend got me kicked out over nothing,” is what she wanted to say, but didn't because that would probably get her fired. “Please just pay for the pizza, ma'am,” is what she actually said.

“Right, sorry. Hold on a moment.” Twilight turned around to rummage through a purse that, for reasons unfathomable to Lightning Dust, was lying on the ground behind her.

She lives in a crystal palace but can't be bothered to not just have shit lying around all over the floor. Or even to put pants on, Dust noticed, though that in combination with the whole bending over to rummage through her purse thing left Dust with very few complaints. Princess Twilight Sparkle has a very nice butt.

“Oh, dear. I seem to be out of money.”

“What.”

“I guess maybe I could pay you in some other way..?”

“What the fuck,” is what Lightning Dust shouldn't have said, but did anyway. She shouldn't have continued but did; “Are you seriously trying to offer me sex in exchange for pizza?”

“Um, yes?”

“Do you know who has to actually pay for the pizzas if you don't?”

“Uh-”

“Spoilers – It's fucking me.”

“Oh.”

“Also, if I showed up at work half an hour late and smelling of sex, my ass would be fired so hard it'd get scorched.”

“Oh.”

“What the fuck were you thinking.” Dust threw her arms up in exasperation. “Aren't you supposed to be the smart one? That's what Dash said the, like, three times she talked about her friends.”

Twilight shrank into herself, blushing and trying to pull her too-small-to-really-cover-anything t-shirt that was the only article of clothing she was wearing into a position that gave her a modicum more modesty (and failing miserably).”The book said that this was the best way to get laid.”

“... What the fuck books have you been reading?”

“Um, hold on.” Twilight's horn lit up and a book floated over. “How To Pick Up Hot Chicks by Tricky Dick.”

“Oh.”

“Is that bad?”

“Little bit, yeah.” It wasn't even a good pickup artist book, which actually explained a lot. “Why would you even need that kinda thing? You're a princess, you could have basically anypony you want. Just go 'hey, you, bed, now' and bam.”

“That's not what the book says, though...”

“Newsflash; books can be wrong.”

Twilight blinked in stunned silence. “... Really?”

“Well, that specific book sure as fuck is at least.”

“Oh.”

“Yeah.”

“So I should find a different book then?”

“I, uh, think this is probably something you shouldn't use a book for.”

“But then how do I know what to do?”

Lightning Dust buried her face in her hands. “Okay, look. You need to pay for these pizzas because if you don't, I have to, and I sure as shit am not taking a 1600 bit hit to my next paycheque because someone thought it'd be a good idea to try and reenact a bad porno because a book told them to. If I wanted to pay 1600 bits for sex, I'd go to a high-end brothel.”

Twilight sheepishly stared at the floor like a dog that had been caught doing something bad. “Okay.”

“And then after work maybe I'll come back and we can, like, talk about this or whatever.”

Twilight's gaze jumped from the ground to Dust in shock. “Wait, really? So you're not mad at me about this?”

“Well, no. I am kinda mad. Buuuuuut,” Dust shrugged, “I'd have to be an idiot to turn down sex with hot royalty.”

“You think I'm hot?”

Dust looked Twilight over. “Well, you've got big tits and a nice ass, and your face is pleasant to look at. Prolly helps that you're only wearing a t-shirt.”

Twilight blushed.

“So, yeah. Here's your pizzas.” She handed Twilight the stack of boxes. “Why do you even need five pizzas, anyway?”

“Oh, for the orgy.”

“what.”

“Well, you know, six mares need a lot of food. And anyway Rainbow Dash said that we could use a few fresh faces or else things'd get stale and the book said that this is the best way to get new people for your orgies, and so I figured I might as well order a lot of pizzas and kill two birds with one stone.” She smiled innocently “Of course, I guess the book was wrong about that. I should scrounge up some bits for the other eight deliverymen.” She handed Dust her bits. “Anyway, when do you get off work? I hope it's soon because Pinkie gets antsy if downtime lasts longer than an hour and trust me, you don't want to see antsy Pinkie Pie. It's not pretty.”

Author's Note

Back to basics: Lightning Dust delivers a pizza.

Nothing explicit in this one, or even really fetishy, but it's hardly safe for work. Also I am rather proud of that punchline.

4 - Griffon a Hard Time

At six feet even, Fluttershy was the tallest member of her small circle of friends, and one of the tallest mares in Ponyville period. She was used to being the tallest. It wasn't necessarily something she enjoyed – she would have much preferred being the smallest and standing out less. But she was tall. She was used to being tall, and, more relevantly, she was used to being the tallest, which is part of why she somehow managed to not see Gilda coming until she had crashed facefirst into something soft and musky.

“Hey! Watch where you're goin', shortstack!”

Fluttershy swallowed heavily, and then slowly turned her gaze up.

And up.

And up.

Gilda was gigantic. She had to be at least ten feet tall – Fluttershy had never been good at judging relative heights, but what was more relevant right now than any numbers was the fact that their relative heights aligned her head perfectly with Gilda's cock and balls.

Her very large cock and balls. Her bottom struggled impotently to contain her massive girth – although her bottom consisted of a pair of daisy dukes that Fluttershy was certain were at least half a size to small and a bright red thong, so “struggling impotently to contain her massive girth” was presumably the effect Gilda was going for. The zipper of the daisy dukes was on the verge of disintegrating from the strain of restraining her gigantic bulge, and the bottoms of her swollen balls peeked out from the legholes. Much like the undersides of her equally huge tits – each one at least twice the size of Fluttershy's head – jutted out from the bottom of her ill-fitting tank top.

Fluttershy found herself rapidly running out of synonyms for “big.” The only things about her that were even remotely small were her clothing. She swallowed nervously.

“What, is there something on my pants or what?” Gilda frowned, leaning down to get a better look at the (much, much, much) shorter mare. “You got a fuckin' problem with me, scrawny?” She prodded Fluttershy in the chest, her taloned finger holding enough force to send Fluttershy sprawling backwards onto her ass. “Fucking pathetic. Kinda cute though. You're Fluttershy, right? Dash's friend?” Fluttershy nodded silently, jaw slack in horrified awe. “Yeah, thought so. You look pretty much exactly how Dash described you. I still can't get over how fucking tiny you ponies are, though. Every time I come down to Equestria it's like stopping in to Midgetland for a visit.” Gilda rose back to her full height and stretched languidly, causing her clothing to creak dangerously. “Oh, and no one makes clothing in reasonable sizes without having to pay out the fuckin' nose, either.” She reached down and gave her balls an idle scratch as her tail twitched back and forth in irritation. “And, I mean, I bought this outfit only a month ago and look at it now! Barely fucking fits.”

Fluttershy swallowed laboriously, blushing furiously and futilely struggling to avoid staring at Gilda's prodigious package. “Um. Hi?”

Gilda raised an eyebrow. Her eyes drifted to Fluttershy's, and then followed her stare, and then grinned lasciviously. “Like what you see, shortstack?” She crouched down and leaned in close, her head dwarfing Fluttershy. “Wanna see more?” she whispered, before standing back up, and up, and up, as straight and tall as she was physically capable of, arms tightly at her sides and legs shoulder-width apart. She closed her eyes and inhaled slowly and languidly, and then opened one a crack, looking directly into Fluttershy's. “Keep your eyes on the prize, shortstack, because things are about to get fun.”

Fluttershy's gaze slowly travelled down, settling squarely on Gilda's cock.

It twitched.

Fluttershy had read in books about situations where something happened and everything seemed to slow down, like time had come to a crawl. What occurred next was the opposite of that. Gilda closed her eyes, clenched her fists tightly, there was a creaking noise, and then a ripping noise, and then suddenly her pants and underwear weren't.

“Aw, yeah. Zero to fully erect in eight point two seconds. New record.”

That was the other, probably more noticeable thing. Proportionally speaking, if Gilda had been the size of a normal pony, her penis would have been around two to three feet long. Gilda was decidedly not the size of a normal pony, and her penis, fully erect, was at least the size of Fluttershy. Probably bigger.

Fluttershy stared, jaw hanging slightly agape. This massive pillar of dark red flesh wobbled in the air before her, like nothing she'd ever seen before in her life. Well, that wasn't entirely accurate – it had elements of dog penis (which she was familiar with from her veterinary work) and it had elements of horse penis (which she was familiar with for obvious reasons). It jutted violently out of a sheath, thick and meaty, before widening into a massive, throbbing, veiny knot, at least the size of Fluttershy's head, if not larger. Slightly farther up its knot was another, smaller knot, and above that, about halfway up the gargantuan length was a third bulge, more like a medial ring than a knot. The rest of the length tapered slowly until it reached the head, which flared out again as wide as the first knot and then tapered to the point, like the head of a dogcock and the head of a horsecock all at once. It was absolutely gigantic – even shrank down to the size of a pony it would have been absolutely absurd, but on someone Gilda's size, calling it absurd was an understatement as immense as it itself was. And that was completely ignoring her balls, each one easily the size of a very large beach ball. The whole thing, from balls to shaft, bulged with throbbing, pulsing veins, each one at least as thick as one of Fluttershy's arms. Gilda's package completely and utterly dwarfed Fluttershy beyond what words could describe.

Gilda's vision moved from her penis to Fluttershy, her grin slowly widening. “Like what you see, shortstack?” Fluttershy could only respond by continuing with her dumbfounded stare, which prompted Gilda's grin to widen even further. “Man, I love coming down to Equestria so much. Makes me feel so fuckin' huge. Would you believe that up home I'm considered a runt?” She knelt down, once again leaning close to Fluttershy, her face inches from Fluttershy's own. The heat of her breath was dwarfed by the moist, musky heat of her cock, like fire and sex and power, overwhelming Fluttershy's meager senses with its sheer magnitude. Gilda whispered directly into her ear; “Well, just you fuckin' wait until you feel the whole thing inside'a you.”

Fluttershy's eyes shrank to pinpoints. “What?!?!”

“Well, yeah, what'd you expect? I'm not gonna destroy my only pair of pants just so you can give me fuckin' blue balls.”

“No!” Fluttershy shouted, desperate survival instinct overriding the sheer intimidation factor of Gilda's girth. “There's no way that will fit inside of me! There's no way even part of it will fit inside of me! It's bigger than I am!”

“And?” Gilda shrugged nonchallantly. “I've fucked smaller'n you, and they took it just fine. You sure you're not just being a little pussy?”

Fluttershy opened her mouth to once again object, but was immediately cut off by one of Gilda's clawed hands darting over her mouth. “Yeah, this conversation is getting old, and I am so fuckin' horny. Now, are you gonna fuck me? Or are things gonna have to get rough?” Fluttershy shivered. “Yeah, thought so. If it makes you feel better, you can just, like, blow me or something. But I'm getting off one way or the other. And trust me when I say that you don't want the other.” Gilda leaned even closer, her beak directly beside Fluttershy's ear, and her penis overwhelming Fluttershy's world. “I mean, unless you want me to just use you as a cock sock until I break you. Because those are your options. Either you be nice to me, or I be very not nice to you.”

Futtershy shivered again, though not with fear.

Gilda grinned.

“Now. Let's get started.”

Author's Note

Gilda episode only the problem is she is too sexually agressive and yeah, she's pretty good at dicking but it's exhausting trying to keep up and nobody can work out how to tell dash she's too pushy,

This one. Holy shit, this one. It took an epoch to finish but damn if it wasn't worth every day of work. At 1300+ words, I literally had to force myself to call it done or else it would have gone way beyond what could reasonably be called a drabble.

The prompt was actually the first prompt I got, before sending prompts for flash-fiction to my tumblr was a thing, and it really lent itself less to a drabble and more towards being a complete pornographic rewriting of Griffon the Brush Off, with Gilda's problem being not that she was an asshole, but that she was overwhelmingly sexually aggressive. The macro and futa aspects are all me, because I have a fondness for those two subjects (in case you couldn't tell. I am rather subtle about it cough cough.)

Out of all the drabbles thus far, this is the first one I feel would benefit from being expanded to a full fic rather than being left on the punchline.

5 - Downsides of Divinity

“Celestia, why the fuck am I nine feet tall.”

“9'1”, by the look of things. A rate of seven inches a day, then?”

“Celestia why the fuck am I nine feet tall.”

“Language, Twilight.”

Twilight began taking a deep breath, but thought better of it when almost immediately her shirt (which she had originally bought four feet and seven cup sizes ago) began to groan ominously. It, along with everything else she was wearing, was already perilously close to ceasing to be, so she decided against pushing her luck. “Okay, fine, whatever, just – please answer my question.”

“Presumably you're nine feet tall because you've been growing.”

Twilight resisted the urge to sigh as that would require inhaling. Instead she just rubbed her temples. “Yes. I gathered. Look, please, I'm really not in the mood for cryptic princess advice.”

“Fine, fine. I don't really have the time to be cryptic anyway. Very busy.” She carefully shuffled her paperwork into a neat stack before removing her reading glasses and looking Twilight dead in the eye. “Now, your question.”

“Why have I gained four feet in the past week?”

“Four feet and one inch, Twilight. And really, you should be able to figure this out on your own, what with the timing and all.”

Twilight's first guess had been that it was an alicorn thing – the timing lined up too perfectly for it not to be related. “But it can't be, because you and Luna and Cadence are all normal sized.”

“Yes, well, Luna and Cadence and I aren't princesses of friendship, are we?

“What does that have to do with anything?”

“Historically, the Princess of Friendship grows very rapidly after her ascension.” She took a sip of her tea. “Really, Twilight, I'm surprised you didn't know this already, considering that it's at least as common knowledge as the fact that the Mare in the Moon was actually real.”

Twilight felt her eye twitch slightly.

“Anyway, you're going to have to do something about your clothing.”

“What?”

“Well, decency laws still apply to you, princess or no. As it is,” she gave a meaningful glance at Twilight's top, “I doubt your shirt will last until tomorrow.” Celestia's statement was punctuated by a ripping noise. Twilight's eyes widened in horror, and her whole body froze in an attempt to prevent her shirt from exploding right into Princess Celestia's face. Luckily whatever it was that tore stopped before any real visible structural failure, although that didn't really change that Twilight's shirt barely covered her breasts as it was. Everything below her nipples, including most of her nipples themselves, was completely visible. The shirt was the largest one Twilight owned – previously, it had reached down to her knees, and had been a dedicated sleep-shirt. Her pants, likewise, had previously been a baggy set of pyjama pants – the roomiest pair Twilight owned – now barely reached mid-thigh length. Flesh bulged out below and above as they futilely attempted to contain Twilight's increased mass.

“Right. Fine. I can do that, I've got Rarity. It'll probably cost a lot, but I can probably have some clothes that'll fit me by tomorrow.”

“Assuming you stop growing now.”

“what.”

“Well, the last recorded Princess of Friendship – honestly, Twilight, you of all ponies should know this – reached a height of about fifty feet before she stopped growing.”

The colour drained from Twilight's face. “I'm sorry?”

“But she grew much slower than you are. It took her a year of an inch-and-a-half of growth per day before she stopped growing.” Celestia took a sip of tea. “At the rate you're going, by that point you will be well over two hundred feet tall. Assuming you even stop at the same point as she did. What with your increased rate of growth, the assumption that everything else will be identical to the last Princess isn't really a very safe one.”

Twilight stared at Celestia in blank horror.

“I would recommend investing in a circus tent or two.”

Author's Note

Alicorns gradually but inexorably grow to about fifty feet over the first couple of years after ascending. Clothes don't come in those sizes. Twilight has to cope.

Nothing much to say here. Sorry for taking so long to post this, folks!

6 - One Night Stand

Magnum Load was no stranger to one-night stands. Just the opposite, in fact; they were practically routine at this point. Go to a bar, find some hot bitch who was plastered enough to have minimal inhibitions, show off his muscles and his bulge a bit, entice her into taking him back to her place, then have some fun. Typically from there he grabbed quick shower and then fucking off back home while she was asleep so he didn’t hafta deal with any romantic bullshit. But, well, the routine had been derailed before he’d managed to get to that point.

Tonight’s ostensible conquest was a maroon pegasus. Her name was Mask something. Masquerade? He typically didn’t put much effort into remembering mares’ names, since he typically didn’t intentionally interact with them more than once. She’d told him her name not that long ago, but it was already beginning to slip from his mind. He was much more concerned with her physical appearance. Reasonably large tits, nice fat ass, shapely hips. Good hair, smelled good. Demonstrated basic hygiene – which you wouldn’t think would be something he’d have to pay attention to, but you got all sorts when picking up random bitches from bars. She looked fit enough, but not stronger than he was, which was an important priority.

Things had mostly gone to plan at first. It had been maybe a bit unusually easy to convince her to take him to her place considering how sober she seemed, but that wasn’t out of place enough for him to notice and anyway she was all over him. If there was one way to get on Magnum Load’s good side, it was to play to his ego. A cute mare fawning over his muscles? Yes please. They’d barely been able to keep their hands off each other on the way to her apartment – they stumbled awkwardly through the door, making out all the while. He had both hands firmly on her ass while she was feeling his package up with one and operating the door with the other. By the time they reached the bed, his pants and shirt had been summarily discarded onto the floor, along with her blouse and bra. She gave him a gentle push, and he quickly picked up the hint and sat on the edge of the bed with his legs spread juuuuuuust enough to show off his bulge straining against his briefs.

Masquerade whistled her approval. “Now there’s a view I could see myself gettin’ used to.”

“Same here,” Magnum said with a big, cocky grin, taking in the topless mare before him. Her breasts were absolutely perfect, nice and big without being too saggy, and the crystal pendant she had on nestled nicely in between them in a tantalizing fashion. And beneath that softness was just enough muscle to be visibly defined.

“So, how big?”

“Foot ‘n a half.”

Another approving whistle. “Nice,” she said, reaching down to remove her skirt.

Which was the exact moment things went off the rails.

“Mine’s bigger, though.”

Her skirt fell to the ground, and Magnum’s jaw very nearly did the same. Her cock was gigantic, straining her delicate pink panties well beyond what should have been the breaking point. Big and thick and drooling, its dark length glistening with moisture. A simple flex of her hips, and her panties snapped, floating uselessly to the floor, unleashing her length in all its glory. Bigger than her god damn torso, easily twice the length of his own member. Complete with big fat fertile balls that very nearly matched her tits. Celestia’s beard, where the fuck was she hiding that monster?!”

“You’re prolly gonna wanna open wider, babe, it ain’t gonna fit otherwise~”

“N-now hold on just a fuckin’ minute here,” Magnum stuttered as he attempted to regain his composure. “You didn’t tell me you had a fuckin’ dick.”

“Wow, he has basic observation skills. I’m almost impressed. Now stop talking and get to sucking.”

“Hell no! I ain’t a fag, I’m not putting your fucking cock in my mouth!” Magnum stood up and stormed his way to the door, grabbing his clothing in the process. Or at least that was the intention. In actuality, he didn’t get beyond standing up before Masquerade calmly placed a hand on his chest and effortlessly pushed him back onto the bed. Naturally, he attempted to get back up, but found himself unable to. Masquerade had placed a foot on his chest and was holding him in place as effortlessly as she’d knocked him down in the first place.

“I don’t think so,” she said, pressing down just hard enough that it started to get uncomfortable without hurting. Magnum found himself caught off guard – he wasn’t exactly small. Built like an earth pony, and an ideal specimen of an Earth Pony to boot. Several hundred pounds of raw bulging muscle. And yet here was this five foot two mare, overpowering him without even the slightest hint of effort. “I’m not done with you yet. Hell, I’ve not even gotten started.”

“I’m not suckin’ your dick, you crazy bitch!”

“Fine, fine, then we’ll skip the foreplay, since you’re so eager,” Masquerade replied with a roll of her eyes. “You kinda look like you’d be bad at blowjobs anyway.” The smaller mare sat down on his abs, quickly grabbing his arms before he had the chance to even try to resist. Once again, he found himself effortlessly restrained in spite of the apparent difference in size and strength. And, of course, this specific position left her cock directly on top of him. It was even fucking bigger this close – long enough to prod him in the face as she began to languidly thrust. He squirmed as best as he was capable of in an attempt to get it out of his personal space. Somewhat unsurprisingly, it responded by growing even bigger. He could feel it pressing heavier and heavier on his torso as it lengthened and thickened and drooled. “Get off of me!”

“Shut up.”

“Mnf!”

“Oooh, yeah, keep talkin’, it feels good against my dick.”

“Mph!”

Masquerade didn’t react to Magnum’s continued indignant grunting. Maybe she didn’t notice, or more likely she didn’t give a fuck. She seemed content to press down more and more heavily on his torso. The bed creaked and groaned beneath their combined weight – her member had to be as big as some smaller ponies by this point. She was heavy, too, enough so that he found himself having difficulty breathing.

Filled with a new sense of urgency, he increased his futile attempts at struggling. All it really seemed to do was make him tired. It felt like all of his strength was just flowing away into nothing. Or, quite possibly, into Masquerade. The weaker and more tired he felt, the firmer her grip seemed to get and the heavier she seemed to weigh on his chest. Likely the result of his dwindling energy leaving him without the ability to properly fight back. But, then, on the other hand, her dick was getting bigger so why not the rest of her?

“That should be good enough!” she said, slowly lifting off of him. “Don’t want you to be too small or there’s no point!”

“What the fuck is that supposed to mean?”

“Why don’t you tell me?”

Magnum gave her a confused and angry glare. What the fuck was this crazy bitch talking about? Dimly, he felt a sinking horror in the pit of his stomach. A deep, primal dread. Knowing that there was something deeply, profoundly wrong before he’d properly taken in the situation.

And there was a lot to take in at once. Masquerade had indeed grown, for starters. He didn’t exactly have a fucking ruler on hand, but the fact that she was kneeling and still very nearly hit her head on the ceiling was telling. It wasn’t just raw height, either. Her breasts were bigger, hips were wider, and she was fuckin’ ripped. Gone was the lithe, athletic figure she’d had at the bar. Were it not for the giant fucking tits she’d look like a god damn bodybuilder. She made him look like a four foot nothing stick figure.

It was at that point in his train of thought that he realized that she didn’t just make him look like a four foot nothing stick figure. “What the fuck?! What did you do?!”

Masquerade casually fiddled with her pendant. “Magic artifact, lets me steal size and store it for future use. You’d be surprised how little of this came from you, actually!”

“Give it back!”

“Nah.”

“What the fuck do you mean ‘nah’?!”

“I mean why in Equestria should I? What are you gonna do, fight me? I’d like to see you try.”

She had a point, unfortunately, but Magnum wasn’t really willing to admit that. “Okay, fine,” he said after a moment. Best to be cautious – as much as he hated it, he was technically at a disadvantage. “You’ve got what you wanted, then? This was some kinda weird sting operation so you could steal my size or whatever?”

“Something like that. I never said I was done with you though.”

“Great,” Magnum replied with weary resignation. At this point if she wanted to fuck him there wasn’t really much he could do to stop it. No matter what he did, he was gonna hafta have a big fat dick inside of him in some permutation. “Fine, whatever, do whatever you want to me.”

“I don’t need your permission. Now hold still.”

He could, he supposed, attempt to fight back against her, somehow. Attempt to come up with some clever way to get around her. It probably wouldn’t even be hard. She was so big, he could probably make it to the door before she could manoeuvre herself to stop him if he really booked it. But, ultimately, there didn’t seem to be much of a point. He had to be at least a few feet shorter, and years of work on his perfectly chiselled figure were just gone. He had to hold his underwear up, lest it fall down and reveal his brand new micropenis to the world.At this point, being forced to do gay shit barely registered on the indignity meter.

Which was an attitude he almost immediately came to regret as Masquerade calmly reached over and grabbed him. He could have handled being fucked, but that wasn’t what she did. Instead, she opened her mouth unsettlingly wide and unceremoniously shoved him in.

Magnum went down quickly and surprisingly easily. He didn’t have the time to resist until it was already far too late. Masquerade had gotten her entertainment out of him, so there wasn’t really much point in lingering, lest he somehow manage to escape. She crawled over to her bed and sat down, causing the frame to creak dangerously. It wouldn’t break, of course – she wasn’t stupid enough to buy a bed that couldn’t handle a significant amount of weight. But she did so love the sound of it struggling to hold her up. She reached down and rubbed the sizable bulge of her stomach. Sadly, it wasn’t as big as it maybe could have been. She might have gotten a little bit carried away with the growth. Stealing his size would probably have been more than enough. But it wasn’t quite as intimidating as filling up most of the room.

“That was- urp!” she was interrupted by a small bit of gas as digestion kicked in, accompanied by Magnum’s briefs. She pulled them out of her mouth and tossed them aside. “That was fun,” she finished. “Now, since someone decided to skip the foreplay, I’m all worked up and need to deal with that.”

She reached down and began to stroke her enormous length, letting out a low groan. Best to take things slow for now. She had all the time in the world, after all.

7 - Repopulating the Species

Chrysalis was a lost cause. That was something that most of the small handful of remaining drones had come to realize almost instantly. Too absorbed in her very specific vendetta against Equestria to actually be in any way an effective leader. She had been a lost cause ever since the invasion, but now that Thorax had turned almost everyone into a technicolour nightmare, she was outright a liability. Those few who managed to escape being made into abominations had quickly come to the unspoken agreement that it was time to find a new queen. They had stolen the remaining unhatched eggs and then ran off without any word to the former queen. The plan probably wouldn’t have worked had it not been for Thorax acting as a (ugh) king, interfering with the hive mind; Chrysalis was probably blissfully unaware there were any remaining unchanged changelings.

Of course, the damage had already been done. The hive was a shadow of its former self. It had already been a shadow of its former self ever since the failed invasion, really, but Thorax’s rebellion had been the final nail in the coffin. Literally transforming the vast majority of changelings into an entirely different species, as though that wasn’t basically dooming their race to extinction. Not that he would admit to that, of course. They’d heard rumblings that this was the changelings’ “true form” or some such nonsense. And in the meantime, the actual changelings had been left to rot.

It wasn’t impossible for them to bounce back from this, of course. But it would take time, and just a bit of luck. The first step was to wait for the stolen eggs to hatch in the desperate hope that at least one of them was a juvenile queen. The odds hadn’t been in their favour – there weren’t exactly many eggs, and juvenile queens were rare. But luck had been on their side, and exactly one of the eggs had been what was needed. It meant they only had one shot, and if anything went wrong then that was it; no more changelings. But it was better than nothing.

The next step was to ensure no one starved to death while they waited for the larvae to reach maturity. It would have been easier if they’d left the other, non-queen children to die. But, well, they needed every warm body they could get for eventually rebuilding the hive.

“Which brings us to the third step,” Regent Spiracle said, adjusting her glasses slightly. “Actually breeding a new generation of Changelings.”

“Okay.” Queen Elytra – or Future Queen Elytra, to get technical – wasn’t quite entirely sold on the whole thing. “Why do you need me, though?”

“Because normal drones can’t get pregnant. Only juvenile and mature queens. And we need you to be pregnant before you can go from the former to the latter.” Spiracle let out an exaggerated sigh, pinching the bridge of her nose in mild frustration. “We’ve been over this. Several times. You should know all of this, child.”

“I do! It’s just... I dunno if I’m ready, is all.”

“It doesn’t matter if you’re ready,” Spiracle said succinctly. “This needs to be done now, so unfortunately you don’t have the luxury of coming to terms with being royalty.”

“Right, right.” Really, she probably should have done all that coming to terms shit in the eighteen years of her life leading up to this point. She knew this was coming the instant she reached sexual maturity, and yet now that it was here she found herself utterly unprepared.

It didn’t help that the initial breeding had been... an ordeal, to say the least. Elytra was a very small person, only four feet tall. Apparently, this was likely the result of food being very scarce given the state of the hive, especially during her formative years. This would also apparently be rectified once she became a mature queen, which was another thing that worried her. The other changelings, or at least the ones not from the same brood as her, had not been severely malnourished in their formative years.

And so Spiracle was a good solid two feet taller than Elytra. She had very severe, sharp features, accentuated by the glasses – the only article of clothing she was wearing. Not that she was unattractive, far from it. As sharp as her features may have been, she was still soft in all the right places. A pert, round ass, wide hips, and large, perfectly formed breasts. A far cry from Elytra, who aside from the soft swell of early stages of pregnancy was very waifish. Small breasts, no real hips or ass to speak of.

And, most importantly, no big fucking horsecock. It was huge, hanging almost to her goddamn ankles and not even hard yet, with an equally impressive set of balls, fat and full and reaching to her knees. Thankfully, the drone they’d gotten to do the initial breeding was slightly more reasonably endowed – only two feet hard. That was the big difficulty that Elytra was having to overcome. Spiracle was just huge and she was gonna hafta take that monster very soon. And she was terrified of it.

But, well, there was no more delaying the inevitable. “Okay, so... how does this work?”

“First, obviously, you need to be pregnant. This triggers your body to produce certain hormones that, when exposed to royal jelly, will trigger your metamorphosis into a mature queen.”

“And, um, I get that royal jelly by...” Elytra trailed off nervously, but Spiracle picked up where the young future queen left off.

“By sucking my cock, yes.” She reached down and jiggled her balls, which let out a loud gurgle in response. “I’ve rewired these to produce quite a lot more than is strictly necessary. Hopefully that will compensate for your... somewhat stunted upbringing.”

“Okay.” Elytra swallowed heavily once again. “Let’s... let’s just get this over with quickly, okay?”

“Okay,” Spiracle replied with a gentle nod. “Open wide, your majesty.”

Elytra, after one final nervous swallow, did as she was ordered. Her regent walked forward and, as gently as was possible, crammed all two and a half feet of flaccid bugcock down her tight throat. “My apologies, your majesty. I’ll try and make this quick.”

“Glrk!” Spiracle’s cock was big, as had been established, and she could feel it pulsing bigger and thicker and harder in her throat. Massive blobs of hot, thick precum flowed directly into her stomach – or pre-jelly, she supposed? Whatever it was, the amounts were almost certainly enough to put any normal cumshot to shame. It felt oddly good, even as she felt her belly beginning to bloat.

“Just allow me to do the work, your majesty,” Spiracle said, her voice showing signs of strain. “You should have enough royal jelly in you shortly, and from there your metamorphosis should begin in about an hour.”

Spiracle’s words just barely registered. It almost felt like she wasn’t even hearing them. They floated in her ears where they drowned in the tingling, almost burning sensation, and the tightness, and the need. She wanted more. She fucking needed more. And she had a sneaking suspicion of how to get it.

Elytra’s body shifted into autopilot, which was fine; it let her focus on other, more important things, like that delightful fullness. Kneeling down as she was left her roughly head level with Spiracle’s balls. Which was good, because it left her hands free to reach over and grab her regent’s big juicy balls and give them a good squeeze.

“A-ah! Y-your majesty, what are you doing?”

“Mgnf,” was Elytra’s response, her mouth far too full of cock for anything more articulate. Not that she was feeling particularly eloquent at the moment anyway – she was more interested in savouring the increase in flow that resulted from the direct attention she was giving Spiracle’s balls. She closed her eyes and relished the sensation. The fullness, the heat, the taste of Spiracle’s flesh, the way Spiracle’s erection was pumping bigger and bigger. It was already so big that it almost hurt in the most delightful way – and a little bit of changeling shapeshifting magic later and her body easily stretched to take whatever Spiracle was capable of. Mostly her belly stretched, swelling bigger and bigger as Spiracle’s output increased with her size, but also her throat was filled with even more cockflesh as her regent’s shaft rapidly came to full mast. A big, meaty knot filled Elytra’s mouth, the flow of precum doubled and then redoubled as her stomach bulged out obscenely, and her balls felt bigger and heavier in her hands as they prepared a climactic release of jelly.

“A-ahn! Your majesty, please, I’m going to- going tooooohhhh fuuuuuuuuckkkkkkkk!”

Spiracle erupted, like a god damn volcano. Clearly she’d not been exaggerating when she said that she’d rewired her balls to produce more than was necessary – if anything that felt like an understatement. Elytra felt her body filling out with gallons of gallons of sweet, sticky royal jelly.

And not just her stomach, she realized. But everything. It felt less like she was being filled with cum – or jelly, whatever – and more like Spiracle was directly injecting her with size. Her hips widened, her ass and breasts filled out, and her whole body grew. Her exoskeleton creaked and groaned as her proportions shifted. Even beyond her body’s overall growth, her limbs got longer. Her horn surged with new length, and with it new power flowed through her veins. She felt like she could do anything. Like a fucking god. She closed her eyes tightly as long, pale green hair flowed down her face like gossamer spider webs, and when she opened them again her vision was different. Deep, shimmering green irises with dark slits for pupils. A queen’s eyes.

Elytra wasn’t entirely sure how long Spiracle’s climax lasted. Hours, days, weeks? She didn’t know, they didn’t have fucking clocks! All she knew was that at some point her growth had knocked Spiracle onto her back, the suddenly much smaller drone’s hips thrusting weakly with the final dregs of orgasm. “I-” she exhaled, before interrupting herself with a grunt and a fresh burst of jelly that slid down Elytra’s eager throat. “I apologize, your majesty.”

“Mn, no need to apologize.” Elytra paused. Was that her? Was that her voice just now? She sounded like a completely different person. Deeper, echoing with power that hadn’t been there before. “It certainly seems to have worked wonders.” It took some effort – her limbs felt like jelly – but slowly, Elytra pulled herself away and stood up.

And up.

And up.

“Oh my,” she said, her confidence briefly slipping as she took in just how huge she was. She towered, an absolute colossus, her horn and ears brushing the cave’s ceiling to the point where she could barely stand up at all. She was taller than some buildings in Canterlot, and probably every building in Ponyville. To say nothing of her figure. Everything about her was huge. She reached down and gave her fat ass a squeeze, relishing in the fact that it was probably big enough that someone could get lost in it forever. Thighs thicker around than five normal sized ponies standing together.Her breasts were easily three or four times the size of her head, big and fat and leaking a sticky, amber nectar ready to feed her coming brood.

And speaking of her brood, her massively pregnant belly practically reached the ground. There had to be thousands, maybe even millions of eggs inside of her, just waiting to be fertilized and laid.Not that it seemed to impede her movement, of course. Were it not visibly obvious, she’d barely even be able to notice it was there.

And she was, she realized as she suddenly found herself having to duck slightly, still growing.

An eager grin spread across her face as she let instinct take over. She allowed her body to fall backwards, her fat ass colliding with the ground like a small earthquake, enough to knock Spiracle off her feet as well. The queen didn’t give her former regent any time to collect herself, spreading her thick thighs wide to show off her eager cunt. “Don’t just sit there, get the others. We’ve got a lot of work ahead of us if we want to repopulate the species.”

She licked her lips eagerly. “And let me tell you, I can’t fucking wait.”

8 - Delicious and Nutritious

There were certain concessions one had to make when one had tits as big as Derpy’s. Certain doors that were too small for her to fit through, places she just plain ol’ couldn’t go. Physical limitations that she couldn’t overcome without cutting down on the boobmass – which was simply unacceptable. It was just a fact of life that her colossal sweater puppies took up more space than most entire ponies. Each. Though “sweater puppies” was a bit of a misnomer because she mostly just wore bikinis. That was another reality of her boobs; they leaked. A lot. The slightest stimulation ran the risk of setting them off, and if another pony got involved it ran the risk of them getting bigger as well. And so Derpy had to avoid tight, crowded spaces as much as was possible.

Or at least that was the case in theory. But, well, Derpy was only equine, just like everyone else. And, just like everyone else, she had her kinks. And the big one was her boobs being too big to fit in a space that she was in anyway.

To her credit, she tried not to engage in that particular kink too often. It was a bit rude to the various passerby and random strangers that it inherently required. And, while Derpy was certainly a very assertive and forward pony, she wasn’t rude. But, well, sometimes she just needed that very specific kind of stimulation. Nothing else would do; she needed a physical, tangible reminder that she was fucking huge. And what better way to get that physical, tangible reminder than to go into a space that was just plain ol’ too fucking small for her and just fucking existing.

The first step was to pick a place. Somewhere with limited space and lots of people. An exceptionally busy shopping mall was a good one, but Ponyville wasn’t super close to any malls so it wasn’t convenient and anyway she couldn’t predict how busy any given store would be on any given day. Which was important because this wasn’t exactly something she could engage in on a daily basis. Or even a weekly basis. So she preferred a more consistent venue, which is why this time she’d decided on a train. Normally that was just the end of it. She bought a ticket, got on a train, and then just waited until she was satisfied she’d been enough of a nuisance to get off a bit. But sometimes even that wasn’t enough for her needs. Sometimes she needed to be a bit more... proactive.

This was one of those times.

The train was not particularly crowded, but that was fine. It was a Saturday morning, it had all day to get crowded and she didn’t plan on leaving any time soon. The good news was that it was exactly crowded enough that she could justify electing to stand rather than sit, and also that there were a bunch of people who had elected to sit rather than stand. Derpy manoeuvred her way through the train, putting in exactly enough effort into dodging other ponies that she didn’t quite succeed but it looked like she was trying her best, before settling on a victim.

Ugh, she really didn’t like using that word. But, unfortunately, it was the right word. There was no denying that she was kind of the asshole in this situation. But that was something she could feel guilty about later. Right now she was more focused on the pony she’d decided to make use of. They had to be sitting, and obviously she’d prefer someone attractive. She’d decided on an athletic looking pegasus with bluish green fur and a yellow mane. She was buff but not too buff. Which Derpy could see because, much like herself, the pegasus mare wasn’t wearing much in the way of clothing. Just a sports bra and some daisy dukes that were just tight enough to dig in slightly to surprisingly ample hips and ass and tits. Not even comparable to Derpy’s massive milkers, of course, but impressive in their own right. Were they not juxtaposed against a literal freak of nature Derpy might even go so far as to call them huge.

And, as a nice little bonus, there was a sizable bulge in the crotch of her daisy dukes, too. Not likely to come into play, but there was always the chance she might turn out to enjoy this and want to come home with her for some more.

Derpy quickly settled into position, looming over the smaller mare – whoever she was looked to be fairly tall, but generally speaking in any given comparison there was going to be more of Derpy than there was of any given other pony short of Princess Celestia herself. There was a moment of silence while the pegasus continued to focus on her phone, not quite noticing Derpy at first. Eventually a frown spread across her face and she looked up. “Excuse me, could you-” whatever words the stranger had dried up as she made eye-contact with Derpy’s mountains.

“Sorry,” Derpy said with feigned innocence. “Not enough space to sit.” That was a lie – there were still plenty of seats free. If the other pony pressed her on that front she’d feign concern for any potential elderly or handicapped ponies who might get on in the near future. “I can move, if you want?” This was her extending an Out. If the other pony elected to have Derpy stay in their personal space, it was tantamount to consent. Or at least that’s what helped her sleep at night.

The other pony’s frown deepened. She didn’t look angry, per se, though. More... conflicted, especially with the way her face had flushed slightly. “... Fine, whatever, it’s almost my stop.”

“Thank you!” Derpy replied, before settling back into silence for now. The other mare continued to frown, but sort of returned her attention to her phone. Sort of, because she very obviously kept stealing glances at Derpy’s scantily clad tits. That was partially an intended effect on Derpy’s part – she liked the sensation of eyes on her body. But also it was another necessity of her anatomy. She was a growing girl, after all, and she could only afford to buy bikinis that fit so often.

The train lurched to life, the inertia setting her tits wobbling slightly. With a smirk, Derpy leaned forward ever so slightly, leaving even less clearance between the stranger’s face and her chest. “Um,” the turquoise mare said, her voice tinged with annoyance and also something else. “A little breathing room, please?”

“Hm? Did you say something?” Of course, that was a lie. Derpy knew exactly what the stranger had said.

“... Never mind.” The stranger’s slight blush turned outright furious as she tried to look anywhere besides Derpy’s cleavage – a difficult task considering it was inches away from engulfing her head. Swaying gently, back and forth. Almost hypnotically. She swallowed heavily, leaning back in the hard plastic seat in a futile attempt to gain some more breathing room when faced with the enormity of Derpy’s tits. She had, at this point, abandoned any pretense of fiddling with her phone, and after a moment of what was probably thought, she slid slightly in her seat in an equally futile attempt to reach her bag, which sat on the floor in between the two mares.

It quickly became clear to her that that wasn’t gonna work, or at least not without her leaving her seat entirely. No, if she wanted her bag, she was going to have to lean forward.

Which was a problem because Derpy was in the way.

“Um, could you please-”

“No.”

“Oh.” Pretense had been abandoned, it seemed. “It’s just-”

“I know. You can reach it without me moving.”

“Yeah, but I don’t want to-”

“Yes you do,” Derpy interrupted again. “Go ahead, I don’t mind.”

“... Right.” The stranger swallowed heavily – at this point Derpy couldn’t really get a good look at her face, but she could hear her swallowing before carefully leaning down and forward in an attempt to get at her bag without burying her face in Derpy’s boobs.

An attempt that was also futile, as Derpy picked that exact moment to pretend there’d been a bump in the tracks and collapse forward on top of her. “Oh, my,” she said. “Somepony’s being assertive. You could have just asked, dear~”

“I’m- I...” the smaller mare stuttered slightly. “Oh Celestia they’re so big.”

“And they’re all yours for now~”

“It, um. It really is almost my stop, ma’am.”

“I know. I just don’t care. And I don’t think you do either.” Derpy leaned in closer, reaching down to grab the stranger’s hands and slip them under her bikini. “If you really want to leave, I won’t stop you. But I don’t think you do.”

“... No, I don’t,” the stranger muttered before leaning deeper into Derpy’s cleavage and beginning to squeeze her nipples.

“Good girl,” Derpy cooed. “Get momma Derpy nice an’ warmed up before mealtime.”

“M-mealtime? Wait, you don’t-”

She didn’t need to finish her sentence. The stimulation from her nimble, athletic hands and the way her body was pressing into them was enough stimulation to get a good trickle going. Of course, a trickle by Derpy standards was gallons by normal pony standards. And this was just the beginning.

“What’s your name, dear?”

“It-it’s Lightning Dust, ma’am.”

“It’s nice to meet you, Dusty. I’m Derpy Hooves, but you can call me Mommy.”

Dust swallowed heavily. “Y-yes, mommy.”

“Now,” Derpy said, licking her lips eagerly as she leaned back just enough to let out Dust’s head. Still gently holding the smaller mare’s hands, Derpy used them to move her bikini top out of the way and unleash leaky nipples onto the world. “Drink up and grow nice and big and strong for momma.”

“I- I- oooooh fuuuuuuuck~” Dust groaned in response. There was a loud tearing sound as the zipper of her daisy dukes failed miserably and something big and long and thick emerged, sliding in between Derpy’s boobs and out the top. It was a darker green than Dust’s fur, and drooled a thick stream of cloudy precum that was very nearly a match for Derpy’s own milk output in terms of volume.

And, as Derpy stared at it, it slowly pulsed bigger.

The smaller pegasus let out a low groan, no longer capable of coherent sentences. Her body slipped into autopilot, reflexively thrusting her hips to titfuck the massive mounds of flesh her cock was wedged between. “Aaaaahngggg~” she moaned, in conjunction with a spurt of precum.

“Don’t worry, baby,” Derpy cooed gently as she leaned into the massive leaky flare, licking her lips hungrily. “You just drink up, momma’s gonna kiss it and make it aaaaall better~”

With that, all of the buildup was over. Derpy took Dust’s shaft into her mouth and began titfucking in earnest, while Dust quickly did the same to one of Derpy’s teats and suckled eagerly.

That was enough stimulation and enough intimacy for Derpy’s condition to kick in. There was a tightness. A warmth. A fullness as her production began to outstrip her output and how much storage she had and her boobs began to grow. And grow. And grow.

And they weren’t the only things that grew. When Derpy had told Dust to drink up and grow big and strong, that hadn’t been entirely euphemistic. Ever since the... incident with Twilight, her milk had gotten significantly more nutritious than it already was. Everything a growing filly needed to grow big and strong. And if you weren’t growing anymore, you would. The effects were sadly not permanent, but usually they lasted just long enough to have some fun.

Dust’s body let out a low creaking noise as her bones lengthened and thickened from all that calcium. There was a low rubbery stretching sound as she got taller, and as more flesh blossomed into existence. Her already ample chest quickly began to strain against her sports bra as her own milk production started to kick in. Her hips widened and her ass swelled and her muscles went from defined to bulging.

And, most pointedly, her balls swelled even more rapidly than Derpy’s tits. They went from cantaloupes to the size of her head and then bigger with no sign of stopping as their cum production kicked into high gear. Fat and fertile and aching for release into the nearest fertile mare.

Which Derpy was perfectly fine with. She was probably going to have to pay to replace the train car once they outgrew it, but she could pretty easily afford that at this point – her milk sold for a lot, it turned out. And anyway, it had been a while since she’d gotten a good breeding. She kind of liked the idea of a foal or two or ten. Or more. Lots more.

After all, there was more than enough milk to go around.
