Cadance strained against the giant crystal doorway trying to crash down on her, using the magical might of ten unicorns and the physical strength of ten earth ponies to keep it open just long enough. Even as an alicorn, she barely had enough in her to do that simple task.

“Go!” She shouted through clenched teeth. “Get the cube!”

The task of retrieving the cube would have to be up to her husband and her sister-in-law. If anypony could do it, they could. And they needed to do it. Legends said that this cosmic artifact – a strange crystalline cube from the sky – was the only thing powerful enough to permanently defeat the Queen of the Changelings. That it was, in fact, what had created the race of changelings in the first place. That it lay hidden in the catacombs deep underneath the Crystal Palace, guarded by a seemingly endless series of traps.

The door Cadance held open was one of the very last traps. She could see the cube now, suspended in some sort of strange angry-looking red energy field in the middle of the circular room beyond. Twilight and Shining ran toward it, ready to finally grab the thing and take it out of here.

Of course there had to be one last trap, though. Just one more. The moment Twilight reached out to grab the cube, that red energy field zapped her hoof, sending her flying halfway across the room. It left Twilight’s hoof blackened, but she seemed not to notice at the moment, instead completely focused on getting that crystal cube. She tried her magic – strangely, it looked almost green in contrast to this intensely red light – but that didn’t work either, her spell reflected harmlessly off the red energy field.

“Your shield, Shining!” she shouted urgently. “Give me the best shield you can, and maybe I can get close enough...”

Shining, ever the perfect soldier, nodded and did what she asked right away – no discussion.

And together, the two siblings slowly approached the energy field. It seemed to pulse redder and stronger, as if sensing their approach, as if trying to warn them away, or maybe threaten them. But they advanced nonetheless.

A terrible clash of magical energies played out as Shining’s spherical shield intersected with the red column. But his shield held. It was his special talent, after all. If anypony could hold a shield against something like that, it was her Shining! And Twilight took full advantage of that, squeezing close to Shining, reaching in and up, right into the flickering, constantly exploding interaction between the two magical fields.

It was too bright – Cadance couldn’t see what was happening. Was Twilight okay? Damn this door! But if she let it fall, all three of them would be trapped in here!

Yes! There was Twilight, flying away from Shining Armor ... with the cube held in her hooves! They’d done it! They’d really done it!

Showing uncharacteristic lack of concern for her brother, Twilight raced straight away, right past Cadance and all the way out the door before skidding to a halt and turning back to look. And then she laughed. Laughed! Why would Twilight stop and ... and cackle like that?

A moment later, Cadance’s questions were answered. ‘Twilight’ was engulfed in a column of green flame, and from that flame emerged ... Chrysalis herself, the cube still between her hooves.

“Fools!” she gloated. “For thousands of years I’ve been trying to get to this cube and I’ve been stopped by the traps every time. And now ... now you’ve led me straight to it and practically given it to me on a silver platter!” She laughed again. “Now, to seal the two of you in there and finally begin the reign of changeling-kind over all Equestria...” Raising one rear hoof, Chrysalis aimed to kick Cadance out from under the door and into the room, sealing her inside.

And there was nothing Cadance could do to stop her. Getting out from under this door would have to be done slowly, carefully. There just wasn’t any time to—

Just before Chrysalis’s kick made contact, Shining Armor came barreling out of the room. He barely made it past Cadance without crashing into her – he did crash into Chrysalis, very much on purpose. He tackled her to the floor in a crunch that sounded awfully satisfying ... assuming it was the changeling’s carapace shattering, not Shining Armor’s bones.

Whichever of them had been the source of that sound, it didn’t seem to slow either of them down. Both wrestled and squirmed against one anther, each desperately grasping for the cube.

Carefully and slowly, Cadance extracted herself out from underneath the heavy crystal door. If she could just...

Too late!

Both Chrysalis and Shining had their forehooves on the cube, trying to wrest it from each other’s grip ... and something happened.

Cadance couldn’t tell quite what it was that happened – the blinding flash of magical energy was just too bright for her to handle, not even with the vision of an alicorn. What she did know, though, was what resulted after the flash. After the flash, there was no more cube and only one ... pony. The pony, if she could even call it a pony, was about Shining Armor’s height and build, but Chrysalis’s colors – dark, dark grey and green. Even the mane was Chrysalis’s sickly blue-green color, as were the lacy, insectoid wings. What ... what had just happened?

“Sh-Shining?” Cadance asked, hesitantly, but hoping for the best.

The pony looked at her. “Uh-huh? Where’d Chrysalis go? Where’s the cube? ... What do you mean where’d I go? I’m right here! Where did you go, ‘Prince’? Where did you run off to with my cube?”

Looking confused to hear its own voice, the pony looked down. It stared at itself for quite some time.

Just as Cadance was starting to get an idea of what might have happened, the pony flashed green again. It wasn’t the huge column of green fire like before ... more like a smoldering green ripple. And, suddenly, the pony was in Twilight Sparkle’s colors again, though still exactly the same shape. It was very strange seeing Shining armor’s body type with his sister’s colors.

The pony looked down at itself again. “Drat! What have you done to me?” it spat venomously, then changed again ... this time to a perfect copy of Shining Armor’s colors, which actually fit the pony’s body size and shape.

Cadance took a cautious step backward ... only to bump her rump into the door she’d just been holding up. Nowhere to run... “Um... Chrysalis? Shining?”

“That’s Queen Chrysalis to—” The pony seemed to suddenly think better of it. “Oh, yes, right. What was I saying? Good work, honey. I think we’ve vanquished Queen Chrysalis forever. Let’s go back up into the palace to celebrate! ... Don’t listen to her! She’s Chrysalis! Or, I’m Chrysalis? Get out of my body! ... You get out of my body, wretched pony! ... It’s my body! I was here first! ... I will cut you out of this body inch by inch if I must – do not force me!”

As strange as it was, things were starting to make a little sense to Cadance. “Shining? Chrysalis? Are you... Are you both in there?”

“Yes! ... No! It’s only me, Shining Armor. ... Don’t listen to her! She’s lying!”

Cadance nodded. “I see...”

“Oh you’ll see alright!” The pony lunged toward Cadance, glowing horn first ... and then suddenly stopped. “Oh yeah? Take this!” The pony punched itself square in the face, knocking itself to the floor. “Ow! ... Idiot! ... I’ll do it again if I have to! I’ll never let you hurt her! ... You mean hurt her again?” The strange pony laughed maniacally. It raised a hoof to punch itself again, but then suddenly stopped, the hoof trembling back and forth in place. “Two can play at this game!”

For a moment, all Cadance could do was stand and stare, blinking, at the strange show in front of her.

But she soon recovered from the shock. She’d long ago learned how to handle strange and stressful situations. Time to get things under control. Or at least a little more under control than they were now. “So ... you’ve been combined into just one pony, Chrysilshine?”

“How dare you call me that? ... I hate to agree with her, but I really don’t like the sound of it.”

Well that settled it. “Chrysilshine it is! Now how about you change back into your true form. After all, you’re not fooling anybody here.”

“Make me!” Chrysilshine stuck out a long, very changeling-like tongue at Cadance ... but also stood up and shook the dust off. “Okay, sure.” The ripple of smoldering green fire flashed down that very Shining Armor-looking body again, leaving it back the way Cadance had first seen: charcoal black with changeling green accents, but still very much in Shining Armor’s shape. “Hey! How did you do that?” Chrysilshine shrugged. “Guess it comes naturally?”

For the first time since that flash, Cadance smiled. This was getting interesting. “So, Chrysilshine, are you a mare or a stallion now?”

“Mare! ... Stallion!”

Well that wouldn’t do. Cadance quickly trotted around Chrysilshine, keeping her head low to get a good look and find out for herself. What she found was ... a bit more complicated than she’d been expecting. Shining Armor’s familiar sheath and balls were there, though they’d also changed colors. But that wasn’t the end of it. She also spotted another strange little opening just above his sheath, as well as a very changeling-looking vulva under his ... her ... their tail. “Uh, actually,” she said slowly, “it kind of looks like you’re ... both. That cube really combined all of you, didn’t it?”

“It was supposed to subjugate ponykind under the rule of changelings for all time!” Chrysilshine seethed. “Actually, it was supposed to kick your butt once and for all. ... Fools! I put those legends in place! The cube could never harm me! This was all a ruse to get you idiots to deliver the cube right into my hooves! ... Well, you say it would never harm you, but look what happened to you now.” They shuddered. “You have to find some way to change us back!”

“Of course, of course.” Cadance nodded. But internally, she was thinking about something very different. This new body that her husband and her arch-nemesis shared certainly had some ... possibilities to it, didn’t it? “Come on – let’s get you back to the palace, and I’ll see what I can do.”

Without waiting for their confirmation, she started trotting out the way they’d all come in.

After just a moment’s hesitation, Chrysilshine followed. “So, let me guess,” they said, “the real Twilight is stuck hanging upside down in some sack of green goo right now? ... What? Don’t be ridiculous. There are far easier ways to get rid of that meddling sister of yours. I simply sent her a chest full of ancient changeling scrolls. They’re just old recipes, but she’ll be in her library translating them for days.” They laughed. “Yeah, that’s my Twiley. Wait – did I just...?”

Cadance grinned. Look at that – already starting to get along! Yes, this was going to work out nicely. Though... “Say, Chrysilshine, honey?”

“Can we revisit that name?”

“I was thinking, once we make it back up to the surface, you should probably change back into Shining Armor’s colors. We wouldn’t want to cause any undue alarm. It’s going to be difficult enough to explain why we’re coming back up without ‘Twilight’.”

“Sure. The less time I spend looking like this, the better! ... Never! I will never submit to your ridiculous pony notions of beauty. You cannot demand that I hide my true—”

“At least for now, okay? Come on. Changing into a pony in order to sneak into the royal palace – it doesn’t get any more changeling than that, does it?”

“Very well. For now.” Chrysilshine changed back into their Shining Armor coloration.

Cadance wondered if they still had their mare parts, and what mare parts in Shining Armor’s colors would look like... Well, that could wait for a little later, couldn’t it?

* * *

Once safely back in their suite at the top of the Crystal Palace, it was a little later and Cadance was more than ready to find out what certain things looked like. She circled Chrysilshine eagerly, but they were holding their tail low, blocking most of her view.

“Just what do you think you’re doing?” they said, with a very Chrysalis-like hiss to it.

She didn’t stop. “If I’m going to fix this somehow, I have to fully investigate what’s going on, don’t I?”

“Trust her,” Chrysilshine said. “Easy for you to say. She just wants to get rid of me. ... Actually, um, I think she might be getting pretty interested. ... Interested? What! No!” They rounded in place, facing Cadance again. “What do you think you’re doing with us? ... Aw, you called us ‘us’! ... Shut up! It means nothing!”

“Look, look. I’m just trying to get a sense of how your bodies merged. I have to figure it out before we can think about how to un-merge them, right?” Of course, she had certain other motivations, but those didn’t need to be mentioned right away, did they?

“Right.” Chrysilshine snorted, rolled their eyes, and looked away. “Hey, don’t be like that. ... Be like what? Oh, I’m supposed to be thrilled at being trapped in the same body with one of the ponies I hate most in all of Equestria, am I? ... You really hate me the most?”

Silence. Apparently, Chrysalis – if Cadance was guessing the two identical voices correctly – didn’t see fit to answer that. Cadance did hope the changeling – or former changeling? – would at least see a little bit of reason, though. “So you’ll let me take a look, then?” Cadance asked.

Chrysilshine raised their tail.

Whether it was both or just one – and which one – who had done it didn’t matter. The important thing was that Cadance could now see her husband’s – no, her spouse’s – cute little vulva.

Wow! He was cute as a mare! Since they were still in Shining Armor’s coloration, their vulva was the same lovely shade of palest pink that she was used to seeing her husband’s cock and balls in. Almost entirely white, but with just a slight flush of pink hinting at the warmth within. In fact, she could see their balls hanging below, the same perfect soft color and also hinting of warmth held within. If everything went well, some of that warmth would be inside her instead very soon!

But that was only scratching the surface of the interesting changes, wasn’t it? “Can you revert to your true colors?”

“Since when do ponies want to see our true forms?” Chrysilshine huffed. “Okay, um... Let’s see if I can figure this out. ... Wait! No! You can’t do that! That’s changeling magic you’re playing with!”

The familiar green glow flowed over their body ... leaving them still in the same shape, but entirely blue from hoof to horn. Cadance snickered a little.

“Huh... This changeling magic takes some getting used to, doesn’t it? ... Incompetent pony!” They changed again, this time into the proper changeling colors. “Do not meddle in my magic! It is beyond your simple mind! ... Oh, so that’s how it works.” They changed again, back into Shining Armor’s colors. Then again, back to the changeling colors. “Neat. ... I told you not to meddle! ... Figured it out easily enough, didn’t I? ... Shut up!”

Cadance did her best to ignore the argument. It felt so strange to hear them talking to themself, both in the same voice. Instead, she focused on something much more pleasing to consider. After all, in their enthusiasm to fight over magic, they hadn’t thought to lower their tail. And now Cadance had a very interesting view. This was not a changeling’s chitinous exoskeleton, despite sharing precisely the same color. This was soft, warm-looking pony fur ... in Chrysalis’s almost-black color. Their vulva, too, wasn’t changeling-like at all. Cadance had become all too familiar with a changeling’s parts when she’d been held in captivity by Chrysalis. But now ... these teardrop-shaped pussy lips were very much like any pony mare’s, soft and supple looking ... still dark, almost black, but with a slight hint of pink inside, not a changeling’s venomous green. She licked her lips.

“Are you quite done yet?” Chrysilshine asked.

Oh, right. Maybe she had gotten a bit distracted. “Not yet!” she said cheerfully, moving around to get a good look under Chrysilshine’s belly.

Things were interesting down there! Of course there were the familiar sheath and balls – very familiar: despite the new coloration, they were exactly the same shape and generous size as Shining Armor’s. Exactly what she was used to, though the new coloration would be a novel change of pace. She wondered if their shaft would still be the same very light pink or if they’d have a new color now. What was entirely new, though, was the subtle slit just above their sheath. If she wasn’t looking so closely, she might not have noticed it at all amidst their almost-black belly fur. Anypony else would probably be entirely clueless as to what it was. But not Cadance. She’d had experience. It looked a little different covered in fur rather than chitin, but she’d recognize an ovipositor slit anywhere. She’d been made to service Chrysalis’s thoroughly enough ... though she’d rarely seen it in this entirely sheathed state.

“Are you quite done staring at us yet, pony?”

Cadance popped out from underneath them. “Almost. I might need to see you in your aroused state first.”

Chrysilshine stuck their tongue out at her. But then said, “Oh come on – just do what she wants. I’m sure she wants the best for us. ... The best for you, more like it. And the best for her own perverted self. ... Like you have any room to talk about being perverted.” They stuck their tongue out again.

Never mind their words. What got Cadance’s attention was their tongue. It was giving her wonderful ideas about just how to get them into that aroused state she wanted to see. “Say ... how about I find a use for that tongue of yours?”

They stuck it out further for a moment. Way out. To the point where it waved in front of their face so they could see it better. Then it shot back into their mouth in an instant. “This tongue?” They made a face. “It’s not even my tongue.”

“But it’s still you using it, right?”

“Well, us using it. ... Hmph! As if I would deign to sully my changeling tongue to pleasure a mere pony. ... It’s not your tongue, it’s our tongue. ... Oh, so it belongs to you now, does it? ... I said our—”

Cadance turned suddenly, facing her rump toward them, spreading her hind legs slightly, and raising her tail high. “Give it to me!” She hadn’t come here to listen to her spouse argue with themself. It was time to get things started.

“... Okay.”

Which one of them had said that? Both? It didn’t matter. What mattered was that they lunged for her, almost taking her off guard with their newfound enthusiasm. Of course, she couldn’t blame them. Her flanks did tend to have that effect on ponies – and changelings – and she very well knew it. That’s exactly why she’d displayed herself so lewdly.

And it couldn’t have been only Shining in control. Because instead of plunging desperately into her pussy like Shining always would, they used their tongue to tease around the rim of her tail-hole.

It made her gasp for a moment, her tail flicking. She had not expected that. Shining had always been off-put by the idea, and Chrysalis had never concerned herself with Cadance’s pleasure in any way. Combined, though ... combined, it seemed to lead to some very interesting results.

Though that initial tease had been delicate to the point of making her fur stand on end, Chrysilshine was not gentle when it came to the rest. They plunged their tongue into Cadance’s unprepared asshole, quickly snaking deep inside. If it hadn’t been so thin and silky-slick, that probably would have hurt. As it was, though, it felt incredible. They were already as deep as she’d ever felt anything in her ass before, and they showed no signs of stopping! All the while, the whole length of their tongue writhed inside her, rubbing every last sensitive bit of her.

Surely, she thought, they’d have to stop soon ... right?

But no. It just ... kept ... coming. Their tongue snaked into her, through her, moving inside of her in ways she’d never dreamed of feeling before. Things had gone quite beyond the realm of pleasure. It would have only felt strange ... if not for Cadance’s perverse nature. Sure, the physical sensations were more akin to something having gone horribly wrong with a recent meal ... but the idea of being so deeply violated tickled her inside more than their forked tongue ever could. She leaned back against them, urging them deeper, urging them for more. This might not be something she’d want to experience over and over again, but it definitely was something she loved the idea of experiencing at least once.

And of course, there still was some physical stimulation to accompany her perversions. Quite nice, in fact. The way their tongue slid in, in, and in was like that sensation of first being penetrated, except that it just kept going and going. Her pussy winked helplessly – and probably a bit jealously – beneath, thirsting for the same deep, endless penetration. It splattered Chrysilshine’s chin a little.

Just when Cadance truly thought they certainly couldn’t be any more coming ... she felt a little flickering contact way down in the base of her throat.

No. It wasn’t possible. They couldn’t possibly have gotten that far, could they?

And yet, there it was. The motion had slowed now – they must have been reaching the limits of their tongue – but the feeling of that thin tendril winding its way up her throat was unmistakable. “Chrysilshine, I—” was all she was able to get out before the rest came out as a garbled mess. It was not easy to talk with two tongues in her mouth.

Finally they stopped pressing inward. Their tongue flickered and danced across Cadance’s own. She tried to play along, to dance her tongue with theirs, but theirs was just so much more nimble and flexible. It was literally able to wrap in circles around hers. And, of course, she absolutely wasn’t used to wrestling tongues with her mouth closed.

Not that it seemed she’d stay that way for long. Already the forked tips of Chrysilshine’s tongue played around the barrier of her teeth, seeking her lips.

So they wanted to go all the way through, did they? Of course Cadance wanted them to. That would perfectly complete this perverse feat of lovemaking! But she didn’t want to give it to them so easily. Where was the challenge in that? So she kept her mouth shut tight, imprisoning the tips of their tongue within.

It didn’t take them long. Shining couldn’t have any clue, but Chrysalis certainly knew what she was doing. She might scoff at the idea of ‘servicing’ ponies, but there was no disguising her level of experience. She certainly knew how. That knowledge was on full display as they began moving their tongue inside her. Inside all of her.

The sensation was incredible. She felt it everywhere from her lips to her tip. Coiling, writhing, waving. And just enough pleasure near her clenching entrance to make her already-perverted mind interpret all of that intense sensation as pleasure. She couldn’t help it – she’d never felt anything like this before – she gasped. Loudly.

That was all the opportunity Chrysilshine needed. Their tongue sprang free from her now-open mouth, shooting outward until it waved proudly in front of her face.

Watching it, Cadance felt like she was being hypnotized. Perhaps she was. Chrysalis’s knowledge would give Chrysilshine many unexpected talents. It moved in time with the churning that filled her whole body, making her feel almost dizzy, as if she was floating on a cloud of tongues, all of them licking her, everywhere, except – somehow – from the inside out. It didn’t make any sense. It didn’t need to. She was far beyond ‘sense’ at this point anyway.

What really did her in, though, was when Chrysilshine’s horn lit up. She couldn’t see it, of course, not the direction she was facing. But she could hear the slight hum – a strange and slightly discordant combination of both pony and changeling magic. More importantly, she felt it: a fast and absolutely merciless vibration against her pussy lips, quickly working its way toward her clit.

That had to be Shining’s doing. It was a spell she’d taught him herself, when they’d first started dating. And it was as effective now as ever. More effective than ever.

The sheer decadence of being penetrated all the way through by their ceaselessly moving tongue, the mesmerizing sight of it waving in front of her face, the perfectly-applied magic of their spell. It all overwhelmed Cadance instantly. She came – she came harder and faster than ever before. It felt like her whole body, from mouth to pucker, was squeezing down on Chrysilshine’s tongue ... and their tongue squeezed back! Instinctively, her lips closed down around their thin tongue, suckling at it as if it was a cock. Her ass spasmed tightly, clenching down on the base of their tongue and sealing it perfectly inside her from both ends. She’d never felt so whole, so one with Shining ... or Chrysilshine. Whichever. At least it was half Shining. At this point, she was well beyond the capacity to care about such petty distinctions.

It wasn’t easy to recover from her orgasm, not with their tongue still dancing through her entire body, snaking through every last twist and turn inside her. But she wasn’t the Princess of Love for nothing. A single orgasm – no matter how intense – wasn’t about to ruin her for an entire day. Not a chance. As her legs finally regained the strength to stand normally, as she finally caught her breath – breathing only through her nose, of course – the tips of Chrysilshine’s tongue brushed along her muzzle, caressing her lips in something like a kiss ... before slurping back into her mouth, down her throat, and beyond.

Cadance could only wonder at what kind of flavors Chrysilshine might be tasting on the way through, but they didn’t seem to mind. As for herself, the whole ordeal left her feeling a bit sore inside and slightly sick to her stomach, but that was a small price to pay for the bragging rights to such a sexual feat.

When she looked behind herself with pride, though, she saw that she wasn’t the only one with her pride showing. Or prides as it may be. Both Chrysilshine’s cock and their ovipositor were fully erect, standing proud underneath their belly.

Cadance licked her lips. She remembered that ovipositor all too well, and Shining’s cock – though now almost black-colored – was as mouth-watering as ever. It was tempting to dive down there and return the oral favor ... but she couldn’t. This was their first time in this new body, and she wanted it to be special. And that meant nothing going to waste. She could have her face plastered with cum and changeling goo later. For now, though, they could be put to better uses.

“Well come on, then,” she said, grinning. “I can tell you want to.”

There was no argument now. Both halves of Chrysilshine's mind seemed to be in perfect agreement about what to do: mount their wife.

Their chest against her rump, their hooves around her waist, their breath against the fur of her back right between her wings ... that was all comfortingly familiar from many nights with Shining in the past. What she felt under her tail, though ... that was a bit more unusual. She had been double-stuffed before, of course, far more often in her college days before getting married. But she’d never before felt two tips touch her with such perfect simultaneity, from the same angle. And, of course, the slick, rounded tip of their ovipositor felt nothing like the blunt warm tip of a proper horsecock.

That didn’t stop her from moaning very agreeably as both slid in at once, though. Never before had it been possible for her to feel two at the same time at such agreeable angles to each other. Their ovipositor slid in easily, aided by the slickness left by their tongue and its own natural lubrication. Their cock was a bit more of a challenge, but Cadance’s wet, winking pussy lips made short work of swallowing it. And that allowed her spouse to slowly, gently slide both shafts into her.

Yes! So warm! So full! Though she knew their cock was bigger than their ovipositor, the ovipositor felt bigger when crammed into her tight ass, despite the oral preparation. Again and again, they thrusted both, both sinking in a little deeper each time until they’d finally double-hilted her. “Oh Chrysilshine!” she cried out. “You feel so amazing inside me!”

“I’m still not sure about that name...” They pulled back slightly, then thrusted back in, hard. “Oh really? Because I’m starting to like it. ... You just like fucking my wife in the ass. ... Jealous much? ... Of course not! Her pussy is way better. ... We’re both feeling the same things, imbecile.” They gave her another rough thrust. “And I think we both know which one feels better.”

Cadance looked over her shoulder at them. “Is ... is that true? Is my ass better? But you always told me...”

They gave her a slow, gentle push, holding themself deep inside her for a moment. “I – I don’t know. I’ve never had an ovipositor before. ... Oh, you’ve had one before. But you might not remember it after all the brainwashing magic I was using on you. ... I mean I’ve never used one before. After I woke up from the brainwashing, I could feel the soreness and I put two and two together. I’m not an idiot. ... Could have fooled me. ... Wouldn’t be the first time. ... Why you—”

“Hey, Chrysilshine!” Cadance flapped her wings, buffeting against their face. “Less arguing and more fucking!”

“As my princess commands.” Chrysilshine laughed. “You got it, honey.”

It was nice to see Chrysilshine getting along with themself. It was even nicer when they started truly giving her the best of both shafts again. And it was so very obvious that they were finally paying attention to her pleasure now, rather than thinking about which of their appendages felt better – there would be time enough later to experiment with that! For now, though, Cadance could enjoy them giving it to her as good as they possibly could. Which turned out to be quite good. Chrysalis had hundreds of years of built-up experience. Shining knew Cadance perfectly and knew exactly what she liked best. The combination of both was just devastatingly effective.

They moved perfectly together, squeezing her waist tightly just like Shining always had when he got excited enough, while also giving her smooth, measured thrusts that hit all the right spots inside her with exacting precision.

Breathing heavily, Cadance gave into it. She even let her tongue hang out a little. No shame here. Not with Chrysilshine. They’d both already seen her in worse states, after all. She could simply brace herself against their thrusts and thoroughly enjoy one of the best ruttings she’d ever received.

The twin shafts moving in perfect sync with each other inside her was one of the best ruttings she’d ever had. If not the best. She certainly couldn’t think of a better one, not in the moment. Both her holes squeezed down in appreciation ... and in growing anticipation of her next orgasm, which surely couldn’t be far off.

Of course, Chrysilshine’s orgasm wasn’t far off, either. Couldn’t blame them. It was their first time in this new body, after all, and they were getting twice the stimulation they were used to.

Just to help push them over that edge, Cadance levitated one of her favorite dildos from the naughty little box beside the bed, quickly aligning it behind Chrysilshine and quite easily inserting it into their already-winking pussy.

Though taken completely by surprise, it seemed to be exactly what they needed. “I love you Cadance!” Chrysilshine said breathlessly into her ear from just behind her head. “We love you,” they said into her other ear.

Cadance’s eyes went wide ... almost as wide as their flare deep inside her. In that moment of incredible revelation, she did an impulsive – and likely quite irresponsible – thing: she used her magic to quickly switch off the contraception spell she always kept on herself. She and Shining had been talking about a baby. Nothing definite yet ... but somehow, the time just felt right. It only took a moment. “I love you too, Chrysilshine,” she said, already feeling her body start to pulse around the twin shafts inside her, instinctively milking them for their special life-giving juice. Did her body somehow know that she’d canceled the contraception spell? It sure felt like it.

Holding themself as deeply inside her as they could possibly go, Chrysilshine finally released. Their cock was the fastest, throbbing as it pumped that familiar cream deep inside her needy pussy. If she concentrated on it, she could feel the warmth of their spreading inside her as they filled her up. She’d heard other mothers say that they could feel it the moment they were impregnated, and now Cadance believed that with all her heart. She could feel the glowing spark of new life inside her.

But that wasn’t to be the only new life inside her. Their ovipositor was a little slower in orgasm, but far more noticeable. She felt the shaft of it swell, stretching her asshole open wide as the first egg slid through, propelled by the powerful muscles inside. Her contraception spell had protected her against changeling pregnancy the previous times ... but not this time. Not after canceling it. She shuddered as she felt the bulge of that egg traveling up through her ass. She gasped when she felt it release deep inside her, a noticeable mass deep within. But the first was only the beginning. As their cock spasmed and unloaded the last of their cum, their ovipositor went on. Another egg. Another.

Another orgasm exploded inside Cadance. The feeling of warm cum pooling inside her, a thick cock filling her pussy, and – above all – bulge after bulge of changeling eggs working their way into her ass ... it brought her to her limit and beyond. Though she collapsed down to the floor, Chrysilshine held her tight, ensuring that they didn’t slip out of either of her spasming holes, ensuring that all their new babies would be planted right down deep where they were supposed to be.

When they finally pulled out of her, Cadance was still shaking a little, both of her holes sill clenching as if trying to keep them inside her just one sweet moment longer.

But, of course, she couldn’t keep that warmth inside her forever. With one last caress of their softening shafts against her inner walls, they slid free. Both their ovipositor and cock popped out at the same moment, freeing a deluge of cum from her pussy and a splash of green changeling goo from her ass at the same time. She shook in place for a moment as she felt the sticky warmth ooze its way down both of her inner thighs.

“I take it you had a good time?”

Difficult to tell which one of them said that. Maybe both. Were they growing closer now? But the answer to their question was easy. Cadance simply nodded. Her body gave another little spasm, and a little more leaked from both her holes.

But what kind of Princess of Love would she be if she let the mere fact of two mind-blowing orgasms slow her down? Already she was recovering, planning her next move.

“Honey, are you okay?” Chrysilshine laughed, smirking down at the leaking princess. “Looks like we ruined her.”

Chrysalis should have known better. Smug bug. Overconfidence had always been her greatest weakness.

Taking advantage of their momentary pause, Cadance suddenly whirled around and lunged at them. Apparently, neither of them had seen this coming. They cried out as she pushed them back toward the bed, and it was all too easy to tackle them back onto it, pushing them over onto their back, with their hind legs hanging off the edge of the bed, leaving them bent backwards at a helpless and uncomfortable angle. The dildo fell out of their pussy, landing wetly on the floor between her hind hooves.

“Unhand me, pony! ... Trust her. She knows what she’s doing.”

Well now it wasn’t hard to tell which one was which. Cadance held them there against the bed just a moment longer, looking down at her captured prey. So strange to see Shining’s face so dark grey, looking up at her with alternations of knowing anticipation and distrustful rage.

She kissed them. “Just leave it to me. One last little ‘test’ I need to do.”

“We have already orgasmed, obviously. I would think you felt it. Perhaps I should have given you more eggs? ... We should have given her more eggs. They’re my eggs too now.” They shuddered. “You must separate us! This cannot stand! ... I’m getting kind of used to it, actually. And you have to admit that triple orgasm felt really good. I felt the same things you did. ... You know nothing of what it is to feel good! ... Oh, well then why don’t you show me?”

“How about I show you?” Cadance said, sliding her way down their body, kissing as she went. Their neck, their chest, their belly ... and then finally right against their two soft, half-withered shafts.

“This is not necessary! We already impregnated you!”

With her hooves, Cadance held both their ovipositor and their cock against her face, one on either side. “Oh, but you were so good with your tongue before that. I have to repay the favor, don’t I?”

Chrysilshine rolled their eyes. “If you must. ... Are you crazy? Cadance’s blowjobs are legendary. ... Even the best pony is nothing compared to the Queen of the Changelings! I’ll have to prove that to you at some point, some point when you can remember it. ... And how exactly is that supposed to work when we’re combined like this? ... What? Does the spoiled prince have an aversion to sucking cock?”

Rather than let them continue to banter, Cadance figured she’d quiet them by showing her own lack of any aversion to sucking cock. Especially her spouse’s cock. She took the head of their cock into her mouth and went straight to swallowing it down.

Quite gratifyingly, Chrysilshine’s argument hushed immediately, replaced by an appreciative moan.

She skillfully worked her tongue and the muscles of her throat to swallow their cock deeper, despite it still being entirely soft. The mix of her own juices and their cum still coating their cock didn’t bother her in the slightest – in fact, she very much enjoyed the heady mix of sexual flavors ... and the changeling ooze from the ovipositor didn’t bother her either. Despite its strange chemical smell, she knew from her experiences in the crystal catacombs that the gooey green stuff actually tasted floral and sweet ... and it was highly addictive. She’d had to quit cold-turkey last time when she’d lost the source of it, but she was looking forward to getting addicted again in the days to come.

For now, though, she just focused on pleasing her spouse’s cock. After all, her experience with ovipositors was limited to only a couple weeks, and she really wanted to impress them during their first blowjob as a combined pair. And, of course, she had her own little plans on what to do with their cum. For that, she’d need a nice big mouthful of it, not have it splattered all over her as she sucked down another clutch of changeling eggs!

Their cock, of course, was responding very nicely to the attention she was giving it, stiffening and growing in her throat. Despite the new and darker color, it was still exactly the same shape and size as Shining Armor’s cock ... which meant that as big as it was, it felt perfectly at home in her throat. She’d overcome her gag reflex when she was only a filly, and this cock was the most comfortable and familiar one she’d ever had in her mouth.

The ovipositor rubbing against her face and her horn was new, though. That added an interesting new wrinkle to things. She played into it, angling herself to give it more contact as it hardened right alongside the cock in her throat. She looked up at her spouse lovingly, despite the bulk of the ovipositor’s shaft mostly obscuring one eye.

Chrysilshine reached down with two hooves. One caressed her, brushing her mane out of her face just like Shining always had. The other grabbed her horn and shoved her downward in a way only one creature had ever dared do to a princess: Chrysalis.

Cadance didn’t mind. The strange combination of tenderness and rough face-fucking as Chrysilshine humped their hips against her open mouth ... it was actually turning her on more than she’d like to admit. But if Chrysilshine wanted to play rough and use dirty little tricks like that ... then why shouldn’t Cadance respond in kind?

She looked up into Chrysilshine’s face and raised her eyebrows slightly, in a way Shining would know to interpret as ‘are you ready?’

Chrysilshine gazed back with a loving smile and nodded slightly. Shining knew what was coming, and he was ready to blow Chrysalis’s mind. Time to show them what the Princess of Love could really do!

Cadance would have taken a deep breath to prepare herself ... if her throat wasn’t otherwise occupied. Still, she took a moment, pausing with her lips against Chrysilshine’s sheath. This took concentration. First came the spasms of her throat. It was like gagging, and also sort of like swallowing ... except that it was completely under her control. She used her years of cocksucking experience to caress each and every little contour of that lovely warm cock with the inside of her throat, paying special attention to all the best spots – not only the best spots that every stallion liked, but the spots that always set off Shining in particular. Right down to the very base of their cock, just past the sheath, where she swirled her tongue in slow, sensual circles. That was only the beginning, though. With her hooves, she gently held up each of their balls, caressing and massaging them with just as much vigor as she knew they could take without feeling any pain. Her horn lit up. Normally, she’d send a tendril of magic up Shining’s ass to complete the picture with a little bit of a prostate massage ... but if her guesses about their anatomy were correct, she now had a much more interesting way to milk their prostate – she slid the tendril of magic into their pussy instead. Just as she thought, where she’d expect to feel the g-spot of a normal mare, her magic felt an all-too-familiar little bump. She rubbed it mercilessly, making sure to caress their clit a little in the process. But that wasn’t the only new addition, was it? If she stretched her wings far enough forward, she could just reach the ovipositor towering in front of her face ... and that was perfect. She lightly brushed up and down its shaft with the very tips of her feathers, knowing the slight stimulation would drive them crazy.

Even she was surprised at how fast the full talents of the Princess of Love had their effect. They cried out, “Cadance, I’m—” And that’s all they were able to get out. Out of their mouth anyway. Out of certain other orifices, there came quite a lot more.

Once again, their cock was the fastest, flaring deep inside her throat and throbbing as it pumped a thick jet of cum straight down into her belly. Normally, she’d plant herself there against her spouse’s sheath and let them enjoy the warmth of her still-spasming throat as they spilled their load inside her ... but she had other plans today. So by the time the second spurt came, she pulled back enough to hold the sticky deluge entirely in her mouth, letting her cheeks puff out in time with the pulsing of their cock.

Their ovipositor soon caught up, spewing huge streams of green slime onto Cadance’s face. As expected, there were no eggs this time. Cadance knew – as few other ponies could – that a changeling’s ovipositor would never waste eggs outside of a pony host’s body. Unless it was sheathed in warm, welcoming flesh, its orgasm would only emit delicious green goo, with not a single egg to be seen. It was a little disappointing that she wouldn’t get to see the bulges of eggs traveling down the length of its shaft, but she had to admit that the warm smothering of changeling ooze pouring over her face had charms of its own. She’d have to get a nice big taste of the addictive substance she’d missed so much ... after she was finished with the cum in her mouth, of course.

Sadly, her mouth wasn’t big enough to hold it all. She had to swallow a little. But she was sure one mouthful would be enough, and she always enjoyed the feeling of cum sliding down her throat anyway.

When Chrysilshine was finally finished, Cadance pulled off of their cock with a lewd slurp, making sure to get every drop of cum she could ... though of course a little still leaked out and dribbled down her lips.

“Wow, honey,” Chrysilshine said between panted breaths, “you – you really outdid yourself that time! ... Yes, even I must admit, your sluttish talents are impressive.”

She wanted to reply, ‘Oh yeah? Well I’m not done yet!’ ... but of course she couldn’t risk spilling the precious load of cum sloshing in her overfilled mouth. Instead, she’d have to let her actions speak for themselves.

With an alicorn-strength twist of her hooves, she flipped Chrysilshine over onto their belly, letting their messy cock and ovipositor hang down against the side of the bed this time. She used her magic to lift up their rump until it was raised right in front of her face.

“Honey, what are you—? Mmm!” Chrysilshine’s leery question faded into quiet bliss as Cadance’s lips mad contact with their clit.

But she had more ulterior motives at play than simply making her spouse feel good one last time for the night. Patiently, she nuzzled and rubbed her lips against Chrysilshine’s dark grey vulva, reveling in its warm, supple softness ... and reveling in what she was about to do. Chrysilshine’s pussy gave one wink, a small one. Not enough. She kept going, teasing them with all the skill of the Princess of Love – at least all the skill she could muster with lips tightly sealed over a mouthful of cum – until she got a proper wink. When their pussy finally winked gapingly open like a truly slutty mare desperate to be filled, Cadance filled them. She planted her lips right against their entrance and forcefully spat their cum into their own pussy, forcing it back inside them with all the pressure her cheeks and tongue could muster.

“Cadance!” Chrysilshine cried out. They must have known what that warm feeling flowing into them meant. But it was too late now. She and they would be pregnant together.

Just to be sure of it, Cadance levitated over the dildo she’d used on them before. It was still slick and wet from the last use, which made it all too easy to plunge into their pussy, pushing much of their own cum into them as it went. She shoved it all the way in, then latched her lips mercilessly against their clit as she moved the big rubber shaft slightly inside them.

It didn’t take long. She wondered if the knowledge that they were impregnating themself had anything to do with how fast they came again. Just their pussy this time, a little squirting orgasm that washed a little of the green goo from her face as their passion spattered over her.

Only then, after they’d properly drawn their own cum in with that orgasm, did Cadance finally withdraw the dildo from their pussy and set it aside.

Exhausted, Chrysilshine flopped down onto the bed. Cadance flopped down next to them. She wasn’t worn out yet, not with the resilience and stamina of an alicorn princess, but she was glad of the opportunity to take a little rest nonetheless.

Chrysilshine’s long tongue hung out of their mouth ... though it didn’t actually seem to impair their ability to speak very much. The flexibility of that tongue was so great that the base of it could form words just as well as the tip. “So, you’re going to work on changing us back now that you’ve had your fun, right?”

“And ruin your pregnancy?” Cadance smirked.

“Oh my goddess,” Chrysilshine said, “I can’t believe we let you impregnate ourselves ... ourself?” They rolled their eyes. “I can’t believe you let her impregnate us with our own seed! ... Hey, you were there, too. I didn’t hear you complaining.” They were silent after that, neither of them wanting to admit how much they’d enjoyed it.

Fine. Let them be in denial. It would just give her more opportunities to tease them about it. “And anyway, why would I want to change you back?”

“Because I’m half disgusting changeling bug now? ... You’re calling me disgusting? You’re the one who shoved our tongue so far up your wife’s tail-hole that we could taste what she had for breakfast!”

“You’re immortal now,” Cadance reminded them. “I’d always been worried about that, having to live forever and losing you after only one lifetime. I’d been secretly consulting with Celestia and Luna to find a solution for that, but so far we hadn’t found anything that could possibly work. But now we have! Look at you! We can be together forever now!”

“But together with Chrysalis forever, too? ... Oh please. I can already tell you’re getting us aroused again just by thinking about it.”

“I’m sure it won’t be too bad. After all, you’ll always be there to keep an eye on her, won’t you?” Smiling sweetly, she whispered, “And besides, I bet she knows a lot of really nice tricks to use in the bed, doesn’t she?”

“More than you could possibly imagine.” The gleam in Chrysilshine’s eyes was pure Chrysalis.

“Really?” Cadance’s smile grew wider. “You might regret saying that to the Princess of Love. I have a very active imagination.”

“Please. How old are you? Twenty? Thirty? ... She’s actually fifty-seven. ... Ha! Only fifty-seven? I’ve been the Queen of Sex for thousands of years. I’ve forgotten more about it than an upstart like you could ever know.”

Cadance didn’t stop smiling. “Is that a challenge?”

“As if you could possibly present a challenge to someone like me. ... Uh, why do I feel like I’m really going to regret being in the middle of this challenge?”

Cadance and Chrysilshine spoke in perfect tandem: “Hush. You know you’ll love it.”

They both laughed. Chrysilshine blushed, but gave an admitting nod.

“Now,” Cadance said, getting back to the business of things, “how should we start this challenge? Blowjob contest?”

“How is that supposed to work? I can’t fellate myself anymore. This new body isn’t nearly as flexible as my old changeling body.”

She shrugged. “We’ll just call in a few of the Crystal Guards. We’ll let them judge our talents.”

“Yep, definitely regretting this. ... You’d better not slow me down, Shining Armor. I do have a reputation to uphold.”

Cadance looked down at their body. “You should probably change back into Shining’s colors, though. We wouldn’t want the guards to be too alarmed.”

“Ugh, fine. But don’t expect me to keep up the disguise forever. You ponies are such gaudy colors. I can’t stand it. ... Hey! I don’t want to spend the rest of my eternal life being all grey either!” Despite the disagreement, they did obligingly change back into Shining Armor’s usual colors, making themself look almost normal.

Nodding her approval, Cadance got up and trotted to the door of their suite, quickly opening the door and poking her head out. As expected, two crystal stallions stood guard just outside.

“Guards, do you think you could come in here and help us? Me and my, um, husband ... we have a little bit of a dispute we need you to settle.”

Author's Note

There's one foal in Chysilshine's womb, two foals in Cadance's womb, and eleven changeling eggs in Cadance's ass (and of course Cadance, Shining, and Chrysalis still) ... in case you were wondering where "17" came from.
