Queen Chrysalis kidnaps Derpy Hooves, intending to make her a broodmare, but then Derpy's boobs get very large and milky and things get out of hand. As is usual, really.

Derpy Hooves has found herself kidnapped by a changeling hive. Their goal; to use her as a broodmare. After the Canterlot Invasion, Chrysalis has found her hive has too many soldiers and not enough hunters, quickly resulting in a food crisis – one she intends to solve by breeding many, many, many more hunters. Unfortunately (or fortunately, depending on how you look at it) for Chrysalis, she has greatly underestimated Derpy's boobs. Presented with many, many, many starving changelings and a thorough breeding, Derpy's condition kicks into full gear.

This goes about as you'd expect.

Repopulation

Derpy Hooves had several questions, but it was one of those situations where she was pretty sure she wasn’t gonna be getting an answer to them. At least not without a fight. Chief among them, “Could you maybe let me down?”

“No.”

“Fair enough. Can’t hurt to ask.”

“Be quiet,” the changeling queen snapped. Derpy was pretty sure that’s what she was. Obviously she hadn’t exactly gotten a good look at one before, but she wasn’t sure what else this woman could be. “Having access to your mouth is a privilege that can be revoked. Right now I’m only leaving your mouth free in case we wish to make use of it later, but I can always glue it up now and unglue it when the time comes.”

“Duly noted.” Derpy elected to shut up, for now. She kind of liked having the option to talk if she wanted, and more to the point she kind of didn’t like the sound of having her mouth glued up. Frankly, there was already too much glue involved for her tastes. She could feel it sinking into all of her nooks and crannies and hard-to-clean places. And she was pretty sure it was already gonna be hard to clean by default, because it was glue. Or, you know, that’s what the as-yet-anonymous changeling queen called it. It was green, translucent, unsettlingly warm, glowed slightly, and there was a lot of it holding her firmly against the wall. It was almost certainly some sorta changeling bodily fluid, but she decided to pretend that it was, in fact, glue. Her arms and legs were completely encased, while her sides were also pretty firmly stuck. Only her head, chest, tummy, and crotch were exposed to the elements.

And speaking of which, her clothes were also gone. That was nice, considering how fucking hard it was to find clothes that fit her these days. Her breasts were well, well, well beyond the standard alphabet at this point, so basically everything she wore up top needed to be custom tailored. And waterproofed, too, because of the milk. She’d tried not waterproofing her clothes, and it ended up being more expensive in the long-run. Derpy milk stains were, it turned out, surprisingly stubborn, so if she ever wanted to wear things other than swimwear she had to waterproof it.All of that added up to a lot of fucking bits.So, y’know, she really fucking appreciated losing an entire outfit. Exactly what she wanted to happen on a Saturday night. Just swell.

The changeling queen looked her up and down hungrily. Clearly, she liked what she saw, licking her lips eagerly. “Yes. Yes, I can work with this.”

“Glad you approve, ma’am.”

“Be quiet.” Derpy rolled her eyes, but once again did not press her luck. The queen went back to eye-fucking her intensely, which Derpy did not at all mind. She liked it when people stared, it made her feel sexy. And that hungry look in her eyes just meant they were definitely gonna fuck at some point, which Derpy was down with. That was actually kinda surprising considering changelings were allegedly strange gross bug monsters, but actually seeing one up close? She was shaped closely enough to just a regular pony that Derpy could vibe with it. It helped that she wasn’t just shaped like a pony, but a very large and generously proportioned pony. Big tits, wide hips, jacked enough to have visible abs without impacting the overall softness, and a really big dick. Yeah, okay, said dick was green and kinda lumpy and glowed a bit, andthere were the insect wings and the weird jagged horn and instead of fur she had sorta shiny rubbery lookin’ skin and her legs kinda had holes in them. But if anything that just added a sort of exotic appeal to her. In short, Derpy definitely would.

“You will do nicely, yes,” the queen continued as though Derpy hadn’t interrupted her. “We’ve been in desperate need of a new broodmare, and you seem to be purpose built for it.”

“I aim to please.”

“Be quiet. It will take some amount of work, of course, but far less than normal. Have you ever been pregnant?”

There was an uncomfortably long period of silence. “Oh, am I allowed to talk now?”

“I asked you a question, slave.”

“My name’s Derpy.”

“Be quiet and answer the question.”

“Mutually exclusive orders! Also, I have two kids.”

“Good. Then we can skip past the boring biological reshaping and to the part where we fuck you until your brain breaks and then turn you into a living incubator.”

“Oooh, sounds fun.”

“Be quiet.”

“Oh, I’ve got work Tuesday through Friday, though. I can definitely work weekends, at least, is that okay?”

The queen clicked her tongue in annoyance. “Broodmares don’t get a say in their schedule.”

“No flexible schedules? That’s not going to be good for your Glassdoor score.”

“That would be devastating if you had the opportunity to say no.”

“Fair enough!”

“You seem awfully glib about this. You do realize that we’re going to turn you into a mindless fuckmachine.”

“You’re gonna try,” Derpy replied with as much of a shrug as she could manage (which was not a lot, given the sheer amount of glue encasing her shoulders.) “Many great minds have attempted, none of them have succeeded. I’m just along for the ride at this point.”

“Hmph.”

“I’m basically already a fuckmachine so really it’s just the mindless part you’re gonna hafta worry about, and if I was gonna get mindbroken at all it would absolutely have happened by now.”

“Be quiet.”

“Yes, miss changeling queen lady.”

“I have a name.”

“And I don’t know it!”

The queen let out a low, frustrated growling noise, and pinched the bridge of her snout. “My name is Queen Chrysalis.”

“Okay! Now we’re getting somewhere. Like I said, I’m-”

“Your name is now Broodmare number 56897323.”

“Wow okay I am definitely not remembering all of that. Waaaaaaaaay too many digits.”

“Lucky for you, you aren’t going to have to worry about thinking for very much longer.”

“Don’t threaten me with a good time.”

“Be quiet.”

“Have you even actually had enough broodmares to warrant that many digits?”

“Be quiet.”

Derpy decided not to push her luck any further, though she did give a playful little smirk that seemed to irk Chrysalis. “I’m going to enjoy breaking you.”

Derpy stuck out her tongue, still feeling playful, and Chrysalis continued frowning. Didn’t rise to the bait, though, which was fine. Derpy had been kind of pushing her luck. As unthreatened as she was by the threats of brain-breaking sex, she was pretty sure that if they wanted to physically hurt her then there wouldn’t be much she could actually do to stop ‘em. Better to just be kind of annoying because while her boobs were surprisingly durable,she was pretty sure they weren’t indestructible yet. Yet.

“Speaking of breaking you, it’s time to get started.” Chrysalis snapped her fingers, and just like that the rest of the hive emerged from the shadows. There were thousands of them, maybe even millions, countless pairs of glowing green eyes filling the vast underground cavern, more and more and more popping out of every nook and cranny until the whole space was lit by a dull green glow.

Two changelings stepped forward, flanking their Queen and trying their best to look ominous despite the fact that frankly they weren’t very good at it. Chrysalis was big and buff and busty, but these two... weren’t, was the simplest way to put it. “What are you feeding them?”

“Be quiet.”

“Because it looks like the answer is ‘nothing’.” They were practically skeletal, for one thing. Derpy didn’t know a lot about changelings – or anything about changelings, really – but she’d gotten the impression they were like horse-shaped bugs, so the fact that she could catch a hint of ribcage underneath their chests was odd. But, on the other hoof, they were shapeshifters, so for all she knew they were faking it. To what benefit, she couldn’t fathom, but it was a possibility.They were also extremely short. Chrysalis herself was very tall, which made it harder to judge. Derpy wasn’t exactly a short mare anymore, and she hadn’t been glued to the wall with her feet on the ground, and she still found herself eye-level with the changeling queen’s fat tits. The two drones, meanwhile, came up just about to crotch-level. Like malnourished children.

Derpy could feel a tingling sensation in her chest just from looking at them. And there were thousands, at minimum. This was going to be interesting.

“Be quiet,” Queen Chrysalis snapped.

“I’m just saying that they look like they could use a nice home-cooked meal. Or two. Or two hundred. Each.”

“Our beloved leader Queen Chrysalis rations out an even amount of harvested love to her subjects!” one of the drones interjected firmly.

“Everyone gets her fair share. It’s just that there are a lot of us.”

“We bulked up our numbers in preparation for the Canterlot invasion,” Chrysalis continued.

“So your solution is to breed more, then?”

“More hunter drones, yes. Right now the hive is mostly soldiers. Good at fighting, bad at collecting love. Which is where you come in.”

“Right,” Derpy said, eyes firmly on Chrysalis’s fat, full, decidedly not malnourished boobs. To be entirely fair, maybe changeling queens were just naturally that big. Or something. That was definitely something that Derpy could believe and not complete bullshit. Especially considering that Chrysalis didn’t even bother to make that excuse, or any excuse.

Chrysalis, if she had any idea about Derpy’s doubts as to her sincerity re; her ability to feed her hive, did not react. She probably didn’t actually care what Derpy thought – which, like, fair, she didn’t exactly expect much empathy from the lady who thought kidnapping a pony with giant tits and turning her into a permanent pregnancy slave was a reasonable thing to do. She snapped her fingers. “Get to work stimulating her while I prepare to Breed.”

“Yes, Your Majesty!”

“You don’t really need to stimulate me.” If anything, it was taking active effort on Derpy’s part not to flood the damn cave at this point. More stimulation might very well be beyond what she could handle, and she didn’t want things to get out of hand too early.

“Be quiet.”

“Is that like your catchphrase or something?”

“Be quiet.” Chrysalis snapped her fingers again, and the drones got to work before Derpy had a chance to make any more snide remarks. The two who were flanking Chrysalis moved first, clambering up her grey fur and latching on to her nipples like little leeches, eagerly sucking away, followed shortly by a stream of more and more and more equally malnourished looking drones that crawled onto her body, latched onto her breasts, and began to lick and squeeze and grope and hump until basically every inch of tit was covered by a changeling. She could feel it all, of course, but most of Derpy’s attention was on the ones sucking her tits. For obvious reasons. Very long story short, when her tits got sucked on they got bigger. That used to be the extent of it, but then Twilight had done some science to try and replicate the effect and in the process made it contagious. Her milk was so absurdly nutritious that drinking it made you temporarily bigger.

And then one day that temporary growth had started to be a whole lot less temporary. People who drank her milk and grew started to find that when they shrank down they didn’t shrink down all the way. Like their baseline had become very slightly bigger. And then, after a few months, not so slightly bigger. Then much bigger. And, recently, a few ponies had reported to her that they hadn’t shrank back down at all. And that was without being in the presence of tens of thousands of extremely hungry babies. Well, okay, probably not actually literal babies, but Derpy’s tits certainly didn’t make that distinction.Just the knowledge that they were there and hungry had been enough to make her tits gain an inch – and that was with Derpy actively attempting to hold back. And now they were suckling, which prompted a quiet rumbling noise.

Normally, she would have flooded the cave with gusto because that’d be hot as fuck. But Derpy hadn’t actually gotten impregnated in the time since her tits had started to really get out of control and, well, she wanted to see just what kind of effect that’d have on the girls. And she was pretty sure that if her boobs exploded with size and milk like they very much wanted to and it was taking every single solitary ounce of willpower and concentration to keep that from happening, Chrysalis would definitely hold off on the whole impregnation thing.

Speaking of which, Queen Chrysalis picked this moment to saunter forward and then get to work on exactly that. No buildup, no foreplay, she just aimed her cock and then shoved it the fuck in, all the way to the hilt, which was almost enough that Derpy lost her cool and grew. She wanted to hold off until at least she got creampied, but man that was tough because Chrysalis’s cock was very big and it felt really good to be filled by it, especially factoring in all the hungry changelings groping and squeezing and sucking her tits. “Mnnnnnffffff.”

“Do you like that, fuckslave? Don’t worry, there’s going to be much more where this came from. We’re going to overwhelm you until you can’t think of anything other than getting bred ever again.” Derpy elected not to mention that that wasn’t all that different from normal – though a lot of that was because she was pretty sure if she said anything she’d lose her concentration and stop being able to hold back.

And she was already pretty close to that point once Chrysalis began to thrust. She was getting closer and closer to her limit, she could feel it. That old familiar sensation of milk welling up in her chest, filling it to the point of bursting and then past the point of bursting, new flesh blossoming into existence as they began to grow in earnest. The changeling queen, for her part, seemed not to have noticed that yet, too busy railing Derpy like a jackhammer. But the drones sure did, more and more of them crawling up onto her breasts to cover the newly cleared space the growth had resulted in. Which felt good.

Really, really, really good.

Another quirk Derpy’s breasts had developed over the years was an almost supernatural sense for when people around her were hungry. That was a big part of why she wore exclusively bikinis, because being in the presence of ponies who needed to be fed made her leak. The more hungry ponies there were, the more her production ramped up. Even adults. Even if they already had food.It didn’t used to work like that – back in the day it was only breastfeeding and intimacy at the same time that made the condition kick in (though of course it was generally difficult to have the one without the other). But, well, now it did. Under normal circumstances it was yet another sexy inconvenience she had to work around, which was fine because she liked sexy inconvenience.

But these were well beyond normal circumstances. There were, to belabour the point, tens of thousands of starving changelings surrounding her. As far as she knew changelings only ate emotions so it wasn’t like her milk could sate that hunger, but her tits didn’t care about that. It was a novel sensation, really, one she had a hard time putting into words, but instinctively she knew what it was – the desire to feed the hungry. She had the breastfeeding, she had the intimacy, she was being railed, and there were an awful lot of hungry to feed. Every single trigger she had, significantly more intensely than she’d ever had it before. It was a miracle that Derpy held back as long as she did, but then Chrysalis pushed her body forward and completely buried Derpy’s face in bugtits which was the final straw.

Derpy opened her mouth, but no noise came out. Not even the croaking ghost of a moan, nothing. That was fine, though, because there was plenty of noise coming out of her tits, along with copious gouts of milk. They erupted, spraying frankly absurd amounts of milk directly down the drones’ throats. The little ones did their best, but no one could have kept up with the sheer volume of fluids that Derpy was producing, and so of course the cave was flooded with sweet smelling milk, quickly reaching Derpy’s knees – which, again, were higher than normal because she was glued to the wall. Oh, and of course they grew, convulsing and lurching larger in big bursts of size, very quickly reaching the ground and then continuing past that as more and more changeling drones continued to mindlessly swarm them.

Chrysalis, if she noticed this was happening at all, was too distracted by Derpy cumming to react. “A-ah! You’re, ah, certainly enthusiastic about this if nothing else.” The queen bit her lip as her thrusting became erratic and her breathing ragged. Derpy could feel the monolith throbbing inside her in a very familiar way – she had two kids, she knew what it felt like when a cock that was inside of you was about to- “Cummmmmmmingggggggggg!” Yes, that, thank you Queen Chrysalis.

Bitch came a lot, too. Derpy hated to admit it because she talked a big game, but she also came a big game. A very big game, geeze. It obviously didn’t compare to Derpy’s current Milk Output, but a normal pony’s average orgasm paled in comparison – and even ponies enhanced by Derpy Milk would have had a tough time keeping up. Naturally, Derpy found herself quickly inflating from the sheer volume of bughorse spunk, until it reached the point that Chrysalis literally couldn’t be inside of her anymore because there wasn’t enough room. Which, given the sheer size of Chrysalis’s penis, took a lot longer than Derpy would have thought. Eventually, Chrysalis’s output made the pegasus so rotund that she was physically pushed out.

It took a few further minutes before Queen Chrysalis actually finished. For someone who was so concerned with breeding, she sure was wasting a lot of cum. “You know,” Derpy said – which took quite a lot of effort on her part considering that her boobs were in fact still being swarmed by changelings. “You could probably have gotten a lot more in me if you’d, like, not glued me to the wall?”

“Mnf.” Chrysalis shot Derpy a dirty look, but most of her focus was on her still ongoing climax. She had fallen right on her ass and was currently pounding the ground as her hips bucked in time with every copious release, resulting in big splashes of milk. Again; lotta cum going to waste.

“I’m just saying that, like, if I were horizontal facing down you wouldn’t have gotten pushed out by your own cum.”

“We need you restrained until you’re too pregnant to escape.”

“Fair enough.” Derpy probably wouldn’t have run away, but she could see how Chrysalis wouldn’t have believed her. “Couldn’t you have just used your goop to glue my hands and feet together or something?”

“Be-”

“Quiet, yeah yeah.” Derpy rolled her eyes.

“Anyway, it doesn’t matter if a few gallons of spunk end up on the floor,” Chrysalis continued, rolling her own eyes and giving a dismissive wave. “If you think I’m only going to fuck you once, you’ve got another thing coming.”

“I would absolutely have judged you harshly if you only fucked me once, lady.”

“Be quiet.” Derpy did as she was told, taking solace in the fact that “be quiet” seemed to be Chrysalis’s way of admitting she’d lost that particular conversation. Instead of continuing to needle the increasingly irritable queen, Derpy turned her attention back to the changelings that were still swarming her boobs. The ones that were actively doing the suckling could not, of course, even slightly keep up with Derpy’s output, hence the lake of milk. Most of it was spraying right back out and contributing to the flooding. But they were doing an admirable job anyway, considering that Derpy’s nipples were so fuckin’ engorged at this point that a grown-ass adult pony would have trouble fitting it in. Most of that was by virtue of the sheer violent force of Derpy’s lactation. At this point they looked more full of milk than Derpy was full of cum, bellies massively distended in spite of the knee-deep flooding. Again; it was actually quite impressive that they could keep up so well and she was surprised it was taking this long for them to get full.

Though, of course, as soon as Derpy turned her attention back to the changelings they popped right off of her breasts and rolled off, making room for more drones to immediately latch on to the geysers and get to suckling – or at least as close to suckling as was possible, given the sheer volume was pushing their faces away. Meanwhile, the two previous drones wriggled and writhed on top of their overfull tums in pleasured satisfaction.

“Hrmph,” Chrysalis grunted, pulling herself to her feet and walking in between the two changeling orbs. “Is that all you two can manage? Honestly, she’s just one pony.” The drones just moaned and burped in response, their bodies letting out loud and uncomfortable gurgles. “Well, whatever. We’ve got plenty of drones, you can afford to take a break, but I’ll be having some words with you about your attitude later.” She turned back and faced the swarm of glowing green eyes. “In the meantime, I want you to work in shifts. Make sure that she doesn’t ever spend more than a second without maximum stimulation.”

“Nice.”

“Be quiet.” Chrysalis turned back to face Derpy, placing her hands on the two overfilled drones. “Let’s see how well you can keep up, little pony. I have an awful lot of drones and they’re all very hungry.”

“Ooooooooh you shouldn’t have said that out loudddddd~” Derpy moaned as her tits lurched a few more cup sizes bigger.

Chrysalis’s confident smirk faltered once again, but she very quickly recovered her composure. “Let’s see how long you can keep this up,” she repeated, leaning more firmly on the drones. Which, really, was not the smartest idea. They weren’t exactly a stable surface, and there was also the obvious side-effects of drinking Derpy milk.

Though, on the other hand clearly Chrysalis hadn’t exactly done her due diligence when it came time to decide what pony to turn into a broodmare, as evidenced by how severely she’d underestimated Derpy. She wouldn’t be surprised if Chrysalis didn’t actually know that particular quirk of Derpy’s milk. It was absurdly, impossibly nutritious – hence the effects of drinking it. Your libido increased, your metabolism went into overdrive, and then your body grew as you digested the meal in a matter of seconds. Of course, on the other hoof, these weren’t ponies, so who knew whether that hyper-nutrition would even have an effect on them.

But on the other other hoof, Derpy knew better than anyone else how bad of an idea it was to underestimate her breasts. The grumbling and gurgling got louder and louder and the drones’ writhing intensified. “A-ah, your Majesty, I feel weeeeeeeirrrrrrd~” one of them moaned.

“Of course you feel weird,” Chrysalis snapped. “Now shut up, I’m trying to gloat.”

“Y-your Majesty, I feel weird toooooooooooo~” the other drone groaned. “Feels goooooooood~”

“Y-your Majesty, I’m- I’m gonna- I’m gonna-”

“I- I- I-”

“Hic!”

“Hic!”

FWOOMPH.

Chrysalis found herself abruptly falling face-first into the lake of milk as suddenly the surfaces she had been putting all her weight on disappeared. She pushed herself upright, green hair absolutely soaked through with a mixture of Derpy’s milk and her own cum. Very clearly put the fuck out, she shook off as much of the mess as she could manage and then turned around to chew out her minions for daring to not be perfectly stable surfaces for her to rest on.

Those complaints died in her throat. If she had skin and not chitin, the colour would have drained from it. Her jaw hung slack as she looked up and up and up.

The thing that most stood out about the drones was that they weren’t drones anymore. Their horns were longer, their wings were bigger, they had pupils and hair on their heads in addition to their tails which was green instead of grey, and most importantly they had the same little crown thingies as Chrysalis, making it immediately clear exactly what Derpy’s milk had done to them. Not exactly what she’d been expecting, but not unwelcome. And Chrysalis’s reaction was very, very, very funny. She sputtered indignantly up at the two former drones – way up, they had to be as much taller than her as she was taller than Derpy.

They were also very clearly no longer malnourished. That, at least, Derpy had seen coming. That was normal, expected. Ponies that drank Derpy milk got bigger, that was just basic scientific facts, extremely well documented, so it made sense that that extended to changelings. What wasn’t normal was for those ponies to also become alicorns. Or, you know, the changeling equivalent of alicorns. Were queens the changeling equivalent of alicorns? Well, if there was a pony equivalent of changing from a drone to a queen, it did not generally happen when they drank Derpy milk. Did it?

Well, whatever, the point was that they were very large and very curvy. Obviously their tits didn’t hold a candle to Derpy’s (duh) but they more than beat out Chrysalis in that regard. Their hips were also wider, asses rounder, waists narrower, and muscles more well defined. Proportionally, too, even if they weren’t almost twice as tall as her they’d still be bigger than her.

Oh, and also their dicks were bigger than hers, that went without saying. Had they had dicks before? Did changelings even have sexes? More questions that she probably wasn’t going to get the chance to ask and that honestly it was entirely possible that the sheer force of her boobs had just permanently changed the answer to. The room was silent, everyone staring up at the newly minted queens while they stood staring at nothing, dizzy and disoriented from the sudden change. The only one who was making any noises at all was Chrysalis, which mostly amounted to nonverbal expressions of irritation.

Which were just loud enough that she didn’t hear it when the rumbling started up again.

Derpy did, though, because she was at ground zero of the next pair of new queens, latched firmly onto her tits and feeding like crazy, sucking and humping and moaning as the rumbling got louder and louder and louder and their moaning also got louder and louder and louder, their humping and sucking more and more intense, their bellies bigger and rounder. Every eye in the cavern was on the two newly minted queens except for Derpy’s, which is why she was the first to notice the second pair of newly minted queens when they ascended. Was that the right word? They popped off of her nipples and cried out in pleasure before once more-

“Hic!”

“Hic!”

FWOOMPH.

They stumbled backwards, each one awkwardly attempting to stay upright in the face of the sudden radical change in their centre of gravity. One of them managed to stay standing; the other fell flat on her ass, right on top of Chrysalis, which Derpy tried her very best not to laugh at and mostly succeeded. In her defence, it was very funny. It was also probably the only reason Chrysalis didn’t immediately order the drones to stop sucking her tits – the next set had already taken their place, eagerly drinking away. More drones climbed on to her body as her breasts continued to grow from the ongoing stimulation, and even more flooded the cavern, wading their way into the knee-deep lake and partaking of whatever the breastfeeding drones couldn’t keep up with.

Chrysalis herself was completely submerged, in addition to being thoroughly sat on. Derpy very briefly worried for the original queen’s wellbeing – as much as getting her comeuppance was very funny, she didn’t really seem to quite deserve to drown in milk. She very obviously agreed, visibly struggling beneath giant changeling ass, thrashing and smacking the larger queen’s body in a desperate attempt to escape. Did changelings breathe? Yet more questions Derpy was probably not going to get the answer to. Either way, Chrysalis was struggling and the larger queen seemed to very much enjoy that. She bit her lips, wiggling her hips to wedge Chrysalis in deeper and deeper in spite of her muffled objections.

“Mnnnnnfffff, s-sorry, your Majesty, it- it just feels sssssoooooo gooooood~” The larger queen, arms shaking, grasped her penis and began to gently pump and then not so gently pump. Panting and bucking her hips which resulted in big splashes of milk. “Oh fuck oh fuck oh fuuuuuck~” she groaned before one of the other new queens wandered over and loomed over her, eyes locked on her shaft, licking her lips hungrily. Chrysalis’s annoyed noises got even louder and even angrier as the two queens did the obvious and began to have sex on top of her. The other two, not to be left out completely, got to making out, rubbing their tits and cocks against each other which was honestly really hot.

Derpy suddenly found herself having a hard time concentrating on that, though, because once again her own body was making itself known. In a way that was basically impossible to ignore – her boobs and belly had gotten so fucking big that they finally blocked her view of the action. “Ah! Oi! Down in front!” Naturally, her body did not listen to her and continued to rise in front of her, further obscuring her view. Annoying. Though, on the other hand, the fact that her belly was also getting bigger at such a rapid pace meant she was very likely gonna have much more pressing concerns sooner than she’d expected. Apparently changelings had a much, much, much shorter gestation period than ponies? Or maybe it was some sort of magic. She wouldn’t be surprised if Chrysalis had cast a spell to make things go quicker, or if the various bits of magical bullshit that had happened to Derpy over the past few years were interacting weirdly with changeling pregnancy. Or both at the same time. Or maybe it was some nebulous third thing, she didn’t fucking know. All she knew was that she really didn’t look forward to laying a massive pile of eggs while still stuck to the fucking wall. “Hey, would one of you mind too terribly helping get me down before I pop?”

“Mnf!” Chrysalis interjected, just barely audible over the sound of fucking.

“Lady don’t even pretend you’re in charge of this situation anymore. Anyway, I don’t think I could run away if I wanted to. Look at me.”

“Mnf!”

“Whose fault is that?”

“MNF!”

“That’s right, yours for not vetting your broodmares more carefully. Really, you should have seen this coming, lady. Anyway, anyone else want to gimme a hand here?” Chrysalis continued to make disgruntled noises. Derpy ignored her, and so did pretty much everyone else. At least she probably wasn’t drowning, or else she’d have stopped complaining by now. “You! On my tits! I know you’re there, I can feel you sucking! When you’re done, get me down from here!” Time was rapidly running out. Derpy could feel something building and building, deep inside of her. It wasn’t a familiar sensation, but she was absolutely certain that she knew what it was. What else could it be besides the feeling of being about to lay a shitton of eggs? Yeah, okay, it felt nothing like when she’d gone into labour with Dinky or Sparkler but also Dinky and Sparkler hadn’t been clutches of eggs big enough that it was obscuring her vision.

And, speaking of which, man Derpy was not mentally prepared to lay a clutch of eggs. She could handle a normal pregnancy easy, she’d done it before and it got easier each time. But eggs? She didn’t know how to handle eggs. Were they eggs? She was pretty sure they were eggs. They kinda felt like eggs. What did eggs even feel like? This, she supposed? It didn’t feel like how Dinky and Sparkler had felt, so she assumed it was something different and that probably meanteggs. What else would it be aside from live birth or eggs?But Chrysalis hadn’t actually said anything about eggs. Did changelings lay eggs? “Do changelings lay eggs?”

“Mnf!”

“Oh, okay, thanks for the clarification.”

“Mnf.”

“Yes, yes, be quiet, I know.” She was, she noted somewhat ruefully, very much still on the wall. Suddenly she could more strongly empathize with Chrysalis’s annoyance at being ignored by the drones. Not that it really mattered, because it was already too late. She could tell. She could feel it. This, at least, was the same as a normal pregnancy. Or, you know, close enough that Derpy could recognize it. Felt a hell of a lot better though. Like a big, thick, hot, wet, throbbing cock getting shoved inside of her, stretching her to her limits and then beyond those limits, except in reverse and multiple times in a row. There were, it turns out, quite a lot of eggs inside of her. Big fuckin’ eggs too. Derpy came, of course, and then came again with every one that forced its way out of her – practically drowning the poor unsuspecting changeling drones that were latched to her tits. Served ‘em right for not helping her down. They were very quickly washed away by the sheer force of Derpy’s lactation, and this time the replacements didn’t immediately latch on because the force of the milk was far too great. Like trying to suck on a firehose turned up to the maximum. They tried admirably but it was a doomed effort.

Not that they actually needed to suck directly on ‘em to get just as much milk in them as the earlier ones, thanks to the sheer volume. Derpy couldn’t see them, because her tits were just too big at this point (and still getting bigger!), but she could definitely feel them ballooning out against her. And also she could feel more of them shoving their faces into the streams, too. Way more than two at a time now – like eight or so per tit, although it was getting harder to count because that was a lot of ‘lings and the eggs were still comin’ and as a result so was Derpy.

Thankfully, as she laid the eggs, her belly got smaller and she actually started to sort of see what was going on. Just in time to see the newest queens sneak up behind the frotting pair and shove their dicks right in there, which they visibly and audibly appreciated quite greatly. That very quickly devolved into some rigorous fucking, which Derpy appreciated quite greatly. “I’d appreciate it even more if I could move my fucking hands,” she said, still somewhat bitter about that.

“Do not let her down!” Oh, hey, Chrysalis had gotten free from under the fuckpile at some point. “You are not going anywhere until I have this situation under control!”

“Good luck with that, lady.”

“Be quiet!” Chrysalis stormed over, sloshing her way through the milk and climbing over the pile of eggs so she could jab her finger into Derpy’s chest. “You may have... transformed a handful of my drones into queens, somehow, but that changes nothing! They’re probably still loyal to me. And even if they aren’t, I’ve got the numbers advantage! There are tens of thousands of drones that are instinctively loyal to me and there is no way you can feed them all!”

“Oh wow that was definitely the worst thing you could have said in this situation lady.”

“Shut up!”

“Oh, hey, you came up with a new line! Good job!” It was, of course, far too late to warn her, so Derpy didn’t bother. She wouldn’t have listened anyway, and also frankly it seemed like she kinda deserved it. She’d been all but asking for it this whole time, and now she was gonna get it. Derpy’s tits rumbled, which was a frustratingly familiar sensation at this point. Thankfully, in this particular instance, they didn’t drag their dang feet. There was a fwoomph as they lurched bigger by a frankly absurd amount, officially reaching the point where they were bigger than Chrysalis and Derpy combined – and by a good margin, too. The changeling queen found herself completely pinned between the massive milkers, and in the meantime even more drones swarmed Derpy’s tits. Her breasts were so sensitive that she could feel every single square inch, even at their current overwhelmingly massive size. There were so many, and they were so enthusiastic about it that honestly she was surprised she could still think straight. But no, not only could she very much think straight, she was almost completely aware of what was going on with her tits just by feeling it, even the parts she couldn’t see. Like echolocation but with her boobs. That probably wasn’t normal, was it. Maybe. She didn’t actually know, she’d never had this many ponies on her at once, all starving and horny. For all she knew, this was how it always worked and she’d just never noticed it before.

“H-hey! Stop that! Let me go!”

“Literally couldn’t if I wanted to,” Derpy replied tersely. “Which I don’t, by the way.”

“That wasn’t a request!”

“If it weren’t for the fact that you’re not the first person I’ve met to be this absurdly obstinate about underestimating my boobs I’d think you were doin’ it on purpose, lady.”
Chrysalis intensified her struggles to escape, although Derpy wasn’t optimistic about her chances. Chrysalis was visibly muscular, yes, and also quite tall. There was no doubt that she was fairly strong. But Derpy’s breasts were very, very, very big. Not just in terms of size, but also in terms of density. They were full of milk, after all, and liquids were often heavier than they looked. And they were getting bigger as well, too fast for Chrysalis to keep up with. Every time it seemed like she’d gotten some leverage they just grew and suddenly she was wedged in again. “Let me go!” she shouted again.

“I think that we’re beyond the point where that’d be possible,” Derpy replied. “Maybe, if I could move my arms and legs, I coulda let you go back when they were only as big as me. Now, though? I don’t think I could move even if you did free me. Which is obviously gonna make freeing you a lot harder.”

“B-be quiet! Let me go! That’s an order!”

“You know, couldn’t you just like shuffle backwards?”

“I’m trying that!” Chrysalis snapped. “I can barely move!”

“Okay well, uhhhhhh... that’s bad? Maybe?”

“What do you mean maybe?!”

“Well, my boobs have never actually hurt someone before, but they’re pretty big right now. If you’re actually stuck, and I’m stuck, then we might have a problem on our hooves.”

“No shit! That’s why I’m telling you to fucking solve it!”

“Yeah you sure do just keep repeating the same things over and over no matter how obvious it is they’re not going to work,” Derpy replied rolling her eyes. “Have you maybe considered tryin’ to get the peanut gallery’s attention? Maybe?”

“I have already tried getting their attention! They keep ignoring me even though I’m the queen and they’re not supposed to be able to do that!”

“I mean, lookin’ at ‘em it kinda seems like they’re queens, too?”

“Not possible! You can’t just become a queen! You’ve got to be born one!”

“Tell that to them.”

“Mnnnnnfffffff,” Chrysalis grumbled, which honestly felt pretty good? Derpy decided not to say anything about it, but all the shouting and the wiggling was really stimulating, especially when she factored in the increased sensitivity. She came a few times, which also made her boobs get bigger, which was really dangerous because it was getting close to an endless feedback loop. As though there was any chance her boobs would stop growing any time soon otherwise. “W-well, maybe they just transformed to look like queens.”

“Can they normally do that?”

“No, but it makes more sense than randomly becoming a queen because they drank some milk,” Chrysalis retorted. “That would be like a pony just... randomly becoming an Alicorn! It can’t be done!”

“Yeah sure,” Derpy replied, thinking of Twilight. “That’s definitely never happened before.”

“You’re being sarcastic,” Chrysalis said, narrowing her gaze.

“Me? Sarcastic? Perish the thought!” She was, of course, being sarcastic. Mostly because she’d given up on the possibility of getting through to Chrysalis. So she’d just embraced chaos. “I’m just sayin’ maybe you should pick up a newspaper once in a century or so to keep up on current events. That’s all.”

“Stop with the snide commentary and let me go!” And that was a sign that Chrysalis had lost the conversation, again. You could generally tell because she started to repeat herself.

“Actually, you know what? Being in my cleavage is probably safer than being outside of it at this point.”

“What the fuck does that mean?!”

“Well, when my boobs get really riled up, they tend to just start goin’. And, uh, at this point? Between all the very hungry changelings and the stimulation and the fact that I was just pregnant and you antagonizing them repeatedly? I think there’s a good chance they might outgrow whatever cave home y’got goin’ here.”

“WHAT”

“Wouldn’t be the first time! Like I said, you guys really need to vet your broodmares more carefully.”

“No! No no no no no! Not happening! Not fucking allowed! You!” she snapped, turning her attentions back to the ongoing orgy. While she and Derpy had argued, it had significantly expanded in scope. There were an awful lot of newly minted queens, and quite a few of them looked to be conspicuously round in the tummy. “You idiots, pay attention! Stop fucking and start working on fixing this fucking mess!”

They did not, in fact, stop fucking and start working on fixing this mess. Derpy was not particularly surprised by that, though Chrysalis seemed incensed. She began yelling incoherently at the drones, at the newly minted queens, at Derpy, and no one paid any attention to her. Everyone’s mind was elsewhere, for various obvious reasons. The drones were entirely focused on Derpy, of course. Whatever feeding frenzy they were in was more than strong enough to override whatever control Chrysalis had over them. And Derpy, for her part, was mostly focused on the drones and the way they were still swarming her boobs. She was, frankly, a little surprised that they hadn’t run out of drones yet. Not that she was gonna complain about her tits getting swarmed, of course! If anything, she was impressed about the sheer population of the hive. And Chrysalis thought the solution to the food crisis was to make more? Although, in a weird way, she had actually stumbled into a much more sustainable food source. Sort of. They’d hafta wait and see if Derpy milk was actually a viable long-term solution for that particular problem, especially considering its tendency to turn changelings into queens.

Although, speaking of queens and overpopulation, the newly minted queens sure were in the process of making that overpopulation problem much more of a problem. Their climaxes weren’t happening in perfect unison, but one after another each participant in the increasingly large orgy came – each one faster than the last, and all of them inside another one. Chrysalis got increasingly angry with every orgasm and each visibly inflated queen. “Stop! No! Not allowed! Forbidden! Bad!” Again, no one listened to her. They were too busy cumming and fucking and fucking and cumming and also now there were a lot more queens.

More than Derpy had expected there to be, actually? She presumed that at least some of ‘em were the result of drinking milk off of the cave floor rather than directly from her tits. In theory, it shouldn’t have made a difference – according to Twilight, the effects were the result of residual magic plus the natural extreme nutritional content of the milk, which meant that even after a few weeks it would still make ponies that drank it bigger which meant that no Derpy you cannot make an extra buck selling it and no, Derpy, you cannot sell it labelled as regular milk that’s false advertising and is supper illegal, no matter how hot you find it.

Derpy made a point of occasionally sneaking unlabelled bottles into the supermarket anyway, much to Twilight’s mild chagrin. Not that she actually stopped her. The point, to put that digression aside, was that technically, according to the usual rules of how her milk worked, drinking it off the floor should still make you grow. But also at this point she had absolutely no idea what the rules even were anymore. Just the one, small change of the drones turning into queens had thrown everything into question because if that worked differently then fuck it, as far as Derpy knew everything worked differently. Or maybe it didn’t. Maybe there were no rules and what she thought were concrete mechanics of how her tits worked were really just Twilight desperately clinging to some sort of rational explanation because she was pathologically incapable of taking anything on faith. Maybe her boobs were just doing whatever was hot in the moment.

In which case, hey, you know what’d be really hot in this particular moment? If all the changeling queens got super pregnant at once, right now. Just full to bursting. Fuck you if that’s not how it works because it’d be hotter if it was! And while she was at it, maybe some sort of amusing karmic retribution for Chrysalis would be nice, too. She had gotten submerged in milk for a while, after all. Fallen on her face after the first two queens transformed and then got sat on for a while, surely she had gotten some milk in ‘er by now, right? Frankly, Derpy was surprised she hadn’t transformed yet. Maybe because she was well-fed enough that whatever nebulous will was behind the effects of her milk had decided she didn’t need to be transformed. Which was well and good enough, losing control of her hive was probably already a huge indignity. But Derpy just couldn’t help but feel like it’d be kinda lame if she didn’t also have to go through some sorta physical transformation by the end of this.

Although, on the other other hand, making her bigger wouldn’t exactly be very undignified. That’d just give her more of a chance of getting the situation back under her control, and obviously that wouldn’t actually help anything. Best case scenario it’d result in a queen fight, which didn’t sound very hot at all. Nah, it’d hafta be something that’d leave her still helpless, at the mercy of the chaos that Derpy’s presence had created. As for what the best way to do that would be, though? Derpy didn’t have any ideas, not off the top of her head. That was fine, though, she had confidence that something fun would happen – it always did.

And anyway she once again found herself with higher mental priorities because she could feel her eggs starting to wiggle underneath her boobs. “Wait, already?”

“Already what, breedslave.”

“Outta curiosity, how long does it usually take for Changeling eggs to hatch”

“Generally one month, why?”

“... Why the fuck do you think I’m asking that.”

“Don’t talk back to me, breedslave!”

“Lady, at this point I’m not sure if you’re stupid, delusional, or both, but you really aren’t in a position to be calling anyone a slave right now.” Chrysalis made some indignant sputtering noises, but frankly Derpy hardly felt it worth paying attention to her at this point. Her head was extremely far up her own ass, or else she would have given up and embraced the chaos by now. “Anyway, what I mean is that I think the eggs I laid earlier are hatching.”

“Wait what? No they’re not.”

“Sure feels like they are!”

“That- that’s not- It takes time for the baby inside of the egg to develop!”

“Well I mean it’s been like ten, fifteen minutes since I laid ‘em.”

“More time than that! There is no way your eggs are hatching any time soon without outside magical interference! And even then there’s a high chance it’d result in weird birth defects!”

“I mean... this would hardly be the first time something weird’s happened because of my milk.”

“Oh yes the eggs magically drank your milk and then hatched minutes after being laid. That makes sense.”

“D’you have a better explanation, lady?”

“Yes! My better explanation is that you are full of shit there is no chance your eggs are hatching.”

“If you say so, lady.”

“They are not,” Chrysalis repeated, although she sounded maybe less than certain about that fact.

“Look. I don’t know any more about how this shit works than you do. There’s some basic rules that things generally follow but beyond that stuff just happens and you kinda gotta go with the flow.”

Chrysalis frowned. “I don’t like that.”

“Yeah, that tracks.” Derpy rolled her eyes. “Anyway, I’d brace myself if I were you.”

“What on earth are you on about now.”

“I mean that, in spite of you being in denial, my eggs are definitely hatching now.”

“So?”

Derpy rolled her eyes. “Do I hafta literally spell it out for you? Oh Celestia I do, don’t I? Okay so remember when I said there’s basic rules my boobs follow? Basic rule number one – when something happens that might cause my boobs to get bigger, it will cause them to get extremely bigger.”

“... And?”

Honestly, like explaining things to a child. “Hey, lady, what happens to your boobs when you have a baby?”

“I don’t fucking know, I’m not a mammal!”

“You’ve got tits, though.”

“Of course I’ve got tits I’m a changeling. We’re shapeshifters that feed off of emotions and especially love did you think we would look like giant bugs? But in spite of appearances we are, in fact, giant bugs.”

“Yes but I’m not a giant bug. If you’re gonna have breedslaves you’d think you’d at least have a basic understanding of how pony pregnancy works?”

“Clearly that would not have been helpful in this situation.”

“... okay, yeah, fair enough, I’m kind of not a typical case.” Still, didn’t actually refute Derpy’s point, but... well, it was a bit too late for warnings. Oh well, couldn’t say she didn’t try and warn her before the eggs hatched. She could feel them crawling around under her chest, slowly making their way out. There was also, of course, a deep rumbling noise from her boobs because of course there was, and it meant exactly what it usually meant. They took their time to actually start growing, thankfully – probably to give her offspring time to scramble out from under them. And there were a lot of offspring. Clearly Chrysalis was a very virile changeling, for all her faults. They were all fairly big and healthy looking, in comparison to Chrysalis’s drones. Very big and extremely healthy, actually. Especially the boobs – they took after their mom in that regard.

And actually, now that she thought of it, they took after their mom in a lot of regards. Their skin was slightly grey, their hair was yellow – and also they had hair at all – and their eyes were also yellow. If Derpy didn’t know any better, she’d have said they were exact clones of her from before she got bred except Changelings. And Chrysalis seemed to agree.

“Why the fuck are they you?!?!”

“What part of ‘sometimes stuff just happens’ did you not get? Anyway, hold on, my tits are gonna grow bigger again.”

“Wai-”

Fwoomph.

“Mnf!”

“Hey, now. Watch your language, young lady.”

“MNF!!!!”

Derpy elected to ignore the rest of Chrysalis’s redundant indignant grumbling. Everything she was saying, she had very much already said. A lot. She was frankly a very repetitive changeling and Derpy was not sorry at all to have consumed her with tits the size of small buildings. Besides, she had other priorities right now. Like, for instance, the fact that she couldn’t actually see. Again. It wasn’t quite as bad as it could have been, she supposed – at least she still had that strange hyper-aware boob sonar thing going on. She could sort of tell what was going on on her tits, if nothing else, but that wasn’t exactly an ideal substitute for seeing what was going on not on her tits. At least she didn’t have to worry about bumping into things because her tits were too big for her to walk under her own power and also because she was still glued to the fucking wall. “Hey! You! Offspring that are apparently also me! Get me down from here!”

“Mnf!”

“Ignore your father and get me down!”

“Yes, mom! Right away!” Well okay that was good, they were at least sort of obedient. Or at least they weren’t immediately ignoring everything else in favour of having lots and lots and lots of sex. Not that she was judging the other changelings that weren’t her offspring for that, of course. Were she in their shoes she would also probably be just a little bit overwhelmed. She could understand where they were coming from, it was just also really fucking annoying in the moment.

“We’re also going to try and get dad out from there before she gets crushed.” Okay well Derpy was less enthused by that, but fair enough. Chrysalis had very obviously not learned her lesson? But also if she hadn’t learned it by now then keeping her in there probably wouldn’t help speed up the process. Letting her out also wouldn’t speed up the process, of course, but fuck it. She just wanted off of the fucking wall.

“Oh, yes, speaking of which. Be careful not to crush the drones.”

“We’ll do our best, but they’re kind off in their own little worlds, you know?”

“We’re only not also off in our own little worlds because we’re a bit more used to, you know, this.”

“Since we’re you, sorta.”

“Mm, yeah, speaking of which, d’you all have any idea what’s up with that?”

“Nope!”

“We think we might be a hive mind, but we haven’t figured out the nuances of that just yet.”

“Fair enough.”

“Good news is we’re pretty sure you’re a part’a that hive mind, btw!”

“Oh, sweet.” Derpy could already imagine many, many, many situations where being a hive mind would be useful to her. She could go to work, parent her children, and have lots of sex. All while being too big to do any of those things properly! A great deal with no downsides, if you asked her. Not a single one, nope. “... Hey, do you guys need to eat?”

“We’re changelings, we eat emotions.”

“Also you of all ponies should know that we come with our own built-in food supply.”

“Right, right, just wanted to check. What about shelter?”

“Ah, that’s going to be a problem. Caves?”

“I’d rather not live in caves, if we’re going to be a hive mind.” Derpy frowned, giving it further thought. “Not that I’m going to be able to fit inside. Or in my house. And you guys probably grow too, don’t you?”

“Probably.”

“We haven’t tried yet, obviously.”

“Obviously,” Derpy replied. Honestly, she was kinda impressed that they hadn’t started growing yet? It was an impressive show of willpower on their part and also by extension her part maybe she still wasn’t sure how that was gonna work. Maybe they were just trying really hard not to think about all the hungry changelings that were still, in fact, swarming her boobs. Derpy could probably stand to follow their example, considering that thought resulted in her gaining a few cup sizes (as though she wasn’t waaaaay beyond cup sizes at this point). She also decided to pretend that they weren’t hungry, despite the fact that they had literally just been born and hadn’t had a chance to eat yet, because otherwise she was definitely going to outgrow the damn cave. Which was going to happen, don’t get her wrong. There was no avoiding it, just delaying it. The goal here wasn’t so much to avoid growing at all, but to at least hold off long enough that she could get a little more sex in.

Derpy wasn’t optimistic on that front. But also she was pretty sure that outgrowing whatever cave they were in wasn’t going to be enough to stop any potential future sex. Again; it was all an inevitability. Derpy was just finagling with the exact order of operations. It’d also be nice to be able to evacuate the hive, but she wasn’t even going to pretend that was an option that was on the table. The hive was fucked and frankly it was their own dang fault. Or at least Chrysalis’s own dang fault.

“There we go! You’re free!”

“We’re just gonna-”

“Ack!” Derpy really should have seen getting rolled over coming, at least enough to brace herself, but her mind was elsewhere. And now her mind was even more elsewhere, obviously – specifically, on the fact that her nipples were now On The Ground and it felt weirdly good. The still very intense flow of milk made ‘em sorta rub against the ground via friction, and also there were in fact still changelings on her tits and they were still suckin’ and wrigglin’ and also getting rubbed by that same friction and some of ‘em had grown into queens so they were very big and very horny and also, again, she could feel everything with perfect clarity and frankly it was A Lot.

Speaking of feeling things with perfect clarity, she could also tell that the Derpylings had gotten Chrysalis out from her cleavage. That was good, she supposed? Right now she was more interested in fighting past the feelings of arousal to take in her surroundings because she could actually fucking see them because she wasn’t glued to the damn wall anymore. She’d been unable to see what was going on for a while now, so there were a lot of surroundings to take in. Many developments while stuck to the wall and blinded by tit. Chief among them were, obviously, the Derpy-clone Changelings. Derplings? Derplings. It was actually kinda creepy? But also kinda hot. It helped that they were extremely busty, of course. Big fat leaky changeling tits did a lotta work. They were sorta shiny, too. Grey rather than black, but it was still clear that they didn’t have fur. Gold eyes, solid without pupils or whites. Weirdly they still had hair? Derpy thought that was a queen thing but also she wasn’t exactly an expert when it came to changelings so whatever. Bug wings, weird spiky lookin’ horns, holes in the limbs, but otherwise they were the spitting image of their mom.

And, of course, big dicks for breedin’. That kinda went without saying, considering that they were shapeshifters. Honestly Derpy was kinda surprised they weren’t bigger. If it were her, and she could shapeshift herself a dick, she’d go with a big fuckin’ dick. But also, now she thought about it, she didn’t need to worry about being mobile right now. “Yeah, part of the whole appeal of the hive mind thing is that some of us can actually fit through doors.” Yeah okay fair enough. She didn’t even need to say anything for them to respond, and they didn’t need to respond for her to intuit the reason. They really were a hive-mind, weren’t they? She was going to have to spend some time testing the mechanics behind that.

Not necessarily right now, of course. She had other priorities at the moment, mostly related to the fact that she was still growing and there were a lot of Derpylings and a lot of non-Derpy changelings who were turning into queens and getting pregnant and laying eggs that were starting to hatch and oh boy were those newly born ‘lings hungry, she could feel it. The point being that the cave was getting more and more cramped at an upsetting pace. They were rapidly running out of room. “Speaking of actually fitting through doors, it might be prudent to start evacuating?”

“Be quiet!”

“oh for fuck’s sake.”

Chrysalis fumed, stomping around like an indignant child throwing a temper tantrum. “I am the queen here! Not you! I get to decide when we evacuate the hive!”

“Look, lady, at this point it’s no longer funny. You can get back to your impotent attempts at regaining control of the situation once it’s no longer actually literally life-threatening. Okay? Okay.”

“Not okay!”

Derpy pinched the bridge of her snout. “Celestia give me strength. Can someone please shut her up for like ten minutes?”

“How dare you! I’ll have you know that hey let me go!!!!!”

One of the Derpylings had, while Chrysalis was ranting, circled behind her and picked her up by her midriff, which was really quite impressive. Derpy was pretty sure that, back before she’d gotten kidnapped, she wouldn’t have been able to manage that. She wasn’t exactly weak, but Chrysalis was big and the Derpyling had effortlessly picked her up off of the ground. “Sorry, your majesty! This is for your own good, we promise. We’ll let you reclaim a shred of dignity after we ensure you don’t get crushed by our tits.”

“We shall do nothing of the soaaaaaaahhhhhhhhhh!”

Derpy struggled to put what happened next into words. It felt very much like a complete random left turn, but here it was, happening before her eyes. Chrysalis’s abdomen inflated with new life like a balloon. Somehow. Despite the fact that, as far as Derpy could recall, she’d never actually gotten a dick in her? “Wh-why am I pregnant?!?!” she cried, clearly just as confused about the development.

“I dunno,” Derpy replied with a shrug. “Probably ‘cause you drank some of my milk? I guess?”

“Drinking milk can’t get you pregnant!” Chrysalis snapped, stating the obvious.

Derpy turned her attention to the other Derpylings and to the changeling swarm, briefly. “Right, you lot. Everyone who can get to the exit, do so. Try and stay calm about it, though? Panic isn’t going to do anyone any good and rushing is just gonna slow things down. If you’re not sure, then head into my cleavage instead. You’ll be safer in there than out.”

Right, okay, there, she’d done the responsible thing. Now she could focus on whatever the fuck was going on withChrysalis. The Derpyling wobbled unsteadily. She’d been able to carry the queen surprisingly easily, but apparently a pregnant queen was more than she could handle. Several other Derpylings swooped in to help hold her steady, but Chrysalis’s body reacted to the extra stability by getting bigger and fuller until her belly eventually hit the ground – and then it kept right on going. “Wh-what’s happening to meeeeee~” she cried as she was slowly lifted up, up, up.

Her belly wasn’t the only thing to grow, either. Of course her boobs got bigger, too. That was the least surprising thing about the whole development, frankly. They swelled right along side her belly, taut and full of Changeling Milk in preparation for her new clutch. Whether or not changelings actually lactated under normal circumstances was up in the air, but this would hardly be the first time that drinking Derpy’s milk had Changed The Rules. Derpy’s boobs had a mind of their own most of the time. She couldn’t predict what they’d do, they just sorta did what they wanted. But, at least, their tastes generally aligned with Derpy’s, and making Chrysalis very pregnant and very milky definitely aligned with Derpy’s earlier desire for Chrysalis to get some sorta comeuppance. She’d kidnapped mares (or, you know, at least the one mare, but it kinda felt like she’d done it more than once) in order to force them into pregnancy and now here she was, forced into pregnancy. Nice and poetic.

Although Chrysalis didn’t seem to appreciate the poetry. “St-stop this at once! I’m not supposed to be the one that gets pregnant, you are!”

“I’m not doin’ anything,” Derpy replied simply.

“Don’t pretend this isn’t your fault!” Chrysalis snapped. Still, even as she complained – and oh boy did she complain, Derpy was surprised she was still finding new ways to phrase her indignity – she was also playing with her growing tits. Squeezing them together, which resulted in a lot of milk spraying forth. She seemed to be having a good time, at least. Certainly seemed to be enjoying herself.

A thought slowly formed in the depths of Derpy’s mind. “Hm. I wonder...” she muttered to herself. Chrysalis didn’t seem to notice, now fully absorbed in fondling her breasts. “Hey! If they’re so inconvenient, why don’t you have some ‘a your many many many hungry offspring help drain them?”

“Be quiet,” Chrysalis snapped – again. “You! Drone! Get over here and drain your queen’s tits before they get too big for her to move!”

Wow okay that was easier than Derpy had expected. Not that she was gonna complain about Chrysalis being cooperative for once. And speaking of miracles, some of the drones that hadn’t evacuated yet actually decided to listen to her majesty for the first time since the feeding frenzy began. Now that Derpy looked, there weren’t a lot left that weren’t queens or buried under her own tits or Chrysalis’s still-swelling pregnancy or in the process of evacuating under the supervision of the Derpylings. Maybe that was why she hadn’t actually outgrown the cave just yet – although she certainly hadn’t stopped, or even really slowed down. Destroying the cave was an inevitability, especially with Chrysalis also growing thanks to her pregnancy.

Several drones crawled their way up the queen’s increasingly absurdly pregnant gut and to her breasts. It was, at this point, bigger than Derpy’s had been when she gave birth, and was starting to firmly jostle against Derpy’s tits. “Ah. Ha! Ha ha ha!”

“What on earth are you laughing about.”

“I may be suffering under the indignity of pregnancy, but my hive still obey me! And there’s more of us than you!”

“Well, I mean, some of your hive still obey you.”

“That’s more than enough! Especially once I lay these eggs! Which should happen any minute!”

“Yeah sure. Good luck with that.”

“Hmph,” Chrysalis grunted with a smug smirk as the drones settled on her breasts and began to suckle. “Just you wai-ah!”

Whatever gloating Chrysalis had was interrupted by her breasts abruptly doubling in size. “Ah, there we go. Called it.”

“Wh-what do you meeeeeannnnnnn~”

“What I mean is that you’re not just abruptly pregnant,” Derpy replied, taking her turn to be smug. “You’ve also got the same condition I do. While pregnant, and getting your tits sucked by very hungry changelings.”

A lot of things happened at once. Chrysalis attempted to reply, but all that came out was a long, low moan. Her boobs grew, of course, as did Derpy’s. The two of them began to press against the walls of the cave. And, most saliently, Chrysalis began to lay her clutch. There were a lot of eggs, more than Derpy had lain, and she was very clearly enjoying herself. It also, apparently, was enough to trigger her boobs to grow faster. Derpy had sort of expected that, but also sort of hadn’t. It made sense, considering how lactation normally worked. But also bugs normally don’t lactate? But also were changelings even bugs? And also also there was the fact that, again, logic hadn’t really played much of a role in things so far so much as horny.

In this case, horny dictated that the changeling boobs get bigger, and far be it from Derpy to complain about that. Naturally, Derpy’s boobs weren’t gonna let themselves get outdone by some bug, and also grew – rapidly. Especially once the many, many, many newly minted queens started to lay their own eggs. Which meant many, many, many more mouths to feed. Chrysalis grew, Derpy grew faster, and within less than a minute they had finally collectively filled the entire cave. Then, less than a minute after that, they un-filled the cave. It was actually a lot less cataclysmic than Derpy had expected, though that wasn’t to say it was underwhelming. Just that she had assumed the cave would put up a bit of a fight before crumbling in the face of the inevitable might of her tits.

“Ha.”

“Oh, I thought you’d gotten distracted by your boobs.”

“Be quiet! I did not get distracted by my boobs! I was just... focused on getting bigger.”

“Sure you were.”

“Be quiet,” Chrysalis snapped again, before doing an admirable job of regaining her smug composure. “And also taking a moment to appreciate your catastrophic mistake!”

“What mistake.”

“Have you not figured it out yet? You said so yourself, I now have the same abilities as you!”

“What are you talking about.”

“My breasts! My invincible, growing breasts!”

“Oh, that? That’s not an ability, that’s a medical condition. Or at least that’s what Twilight says.”

“So small-minded! Appropriate from a Pony, completely unable to grasp the power afforded to you by your natural gifts! But that just means that I’ll be able to put them to much better use! And I’ll start by turning the tables on you.”

“Man you really do lean into the whole supervillain bit, don’cha,” Derpy said, tilting her head. “Alright, you’re clearly having fun so I’ll bite. How do you intend to turn the tables on me?”

“Are you stupid? I’ll use my magic milk to make an army of loyal changeling queens! No more population crisis if everyone can lay an army’s worth of eggs! And then I’ll take over the world!”

“Ah. Okay, I see where the misconception is comin’ from.”

“wait what do you mean by that”

“So, like, remember when I said there were rules? I’m pretty sure I said there were rules. Did I?”

“You said nothing of the sort.”

“Well, okay, there’s rules. Sometimes they’re kinda abstract and go more on vibes than anything, but there’s a couple of specific things that are consistent, even when my condition spreads to other ponies. Which, by the way, you’re not the first person who that’s happened to. Not even the third.”

“Hmph. I wasn’t under the illusion that I was.” Chrysalis awkwardly crossed her arms over the massive boulders on her chest. “Fine then, what are these so-called rules.”

“Well, for starters, all the contagious growth and the spontaneous pregnancy and turning into changeling queens shit? That’s not a part of the condition. That’s just me.”

And, just like that, Chrysalis deflated. “Oh. You- you’re sure?”

“Yep. One hundred percent. It’s only ever been me. Even when Twilight actively tried to replicate all of those effects it just carried over the base condition. Nothin’ else.”

“Oh.”

“Sorry to put a damper on your plans for world conquest.”

“Hmph. Very well.”

“You know, you’re taking this awfully well.”

“Be quiet. Of course I’m upset, but my hive is still loyal to me. I can just order them to suck my tits and take solace in the fact that I’ll end up much bigger than you.”

“Ah, nope. That’s another one of the rules, no one ever ends up bigger’n me.”

“Oh come on.”

“Hey, I don’t make the rules! My boobs do.”

“Well fuck your boobs then!”

“You’d like that, wouldn’t you?”

Chrysalis went back to blushing furiously and stammering in indignant rage. “F-fine! I won’t be able to get bigger than you! And I don’t have your powers! But I don’t need your powers to breed an army because I already have! Look at all these fucking eggs, and those are just the ones I laid! Now that the new queens have calmed down I’m sure they’ll go back to obeying me, and by extension so will their clutches!”

“Fair enough! Speaking of which, it looks like they’re hatchin’.”

“Of course they are,” Chrysalis said, voice dripping with irony. “Fine. Whatever. Your boob magic shit made them gestate faster. Fine. They’re still decidedly mine.”

“Oh, I’m sure they are,” Derpy replied. She had an inkling that Chrysalis was jumping to more than a few conclusions there. That those offspring weren’t gonna be quite as loyal as she assumed, at the least. Chrysalis’s smug grin faltered, just a little, at Derpy’s response, but she quickly regained her composure as all of the eggs began to hatch.

Only for it to immediately fall again once she saw what was hatching.

They were not, to be fair, all Derpylings, or even mostly Derpylings. A solid twenty, twenty five percent or so? Enough that Derpy wasn’t worried about the changeling species getting overridden by Derpy, but also enough that she was pretty sure that specifically all of Chrysalis’s clutch were Derpylings. Or at least she hoped so. Because it would be very funny.

Chrysalis stared down in abject horror as the newly born changelings and Derpylings alike immediately began to make out. Of course they did, that’s what Derpy would do in the situation and strictly speaking they were Derpy. “Well, there ya’ go. Your army. Very intimidating.”

Chrysalis made a series of very complicated facial expressions – the only real thing that Derpy could say for sure about the emotions being conveyed was that there were a lot of them and that they probably weren’t positive ones. “I- you- Mnnnnnf.” Eventually she settled on a furious blush and petulantly puffing out her cheeks, like a child throwing a temper tantrum. Which, really, wasn’t too far off. She wasn’t a child, but frankly this whole event had just been one big temper tantrum on her part. “Mmmmmmmnnnnnfffff!”

Admittedly, Derpy didn’t have to rub it in quite so hard. She was just in a bit of a bad mood, that’s all. As much fun as she’d had, the whole thing had absolutely been very inconvenient. So she was snippy, sue her. “You look like you’ve got something to say?”

Chrysalis stammered and stuttered some more, returning to the angry facial expression roulette. “Y- Youuuuuuuuuu-”

“Be quiet?”

“...” Chrysalis settled on a simple frown. “You took the words right out of my mouth.”
