Nuptial Flight

In the sleeping land of Equestria, three little ponies shivered around a dying camp fire, huddled in a gloomy cave. The night was cold and dark, the moon obstructed by rumbling clouds. A bolt of lightning ripped the sky open, the resulting boom echoing across the walls of the deep cavern, reaching the former sirens.

Sonata Dusk couldn’t help but squeak, her hooves fidgeting nervously as she stoked the fire. She and her sisters had been caught unawares by the storm, and it was by sheer luck they had found this cave. They had gone far enough to escape the biting winds, but the thunder still reached them. Adagio had refused to go deeper into the cave system, who knew what creatures could lurk in the underground. The sirens had been absent from Equestria for a millennium, they had to learn to adapt to a new world once again. And new bodies. Once again.

“I hate being a pony!” Aria spat. She had been the least enthusiast about their new form, and the slowest to adapt to being a quadruped.

Sonata couldn’t help but smile at the memory of her big sister face-planting every three steps as they sneaked out of the Crystal Empire. The security in the castle had been shockingly lax, the mirror wasn’t even guarded! All their planning for nothing, that sure had sent one of them into a fury. The azure earth pony glanced at their leader, currently deep in thoughts about their next move. Or Adagio could just be pouting, Sonata was never sure.

“Fuck!” Aria stumbled and fell , doing her best impression of a newborn deer. “I hate Equestria!”

“Keep it down.” Adagio snapped. “We don’t want anyone to find us.”

“Like who?” Aria stood on shaky legs, her purple fur matted with dirt. “There’s no one stupid enough to be out in a storm like this, except us!”

“Shut it.”

“Face it Adagio, coming back was a stupid idea. All those nights sneaking around that stupid school, testing that stupid statue, stealing guns…” Aria snarled in rage. “We didn’t get our magic back, we’ve been transformed into stupid earth ponies and our guns turned into pies!”

“At least they were tasty…” Sonata eeped as her sisters rounded up on her, Aria promptly stumbling on her side. She was used to being a little smaller than her sisters, in siren or human form, but her pony body was just tiny! It made her sisters much more intimidating.

“Be that as it may,” Adagio breathed, ignoring the fallen pony screeching curses “all is not lost. Can’t you feel it girls? We may have lost our powers, but they are slowly coming back."

"But our pendants are still gone..." Sonata whispered, rubbing her chest mournfully.

The source of their powers had been shattered by a group of humans led by two transformed Equestrians, Twilight Sparkle and Sunset Shimmer, names forever etched in their hit list; the red mystical jewels had fallen to pieces when the detestable magic of harmony had washed over them, the useless shards falling to the ground. They were then powerless, desperate, did awful things to survive, but one thing kept them going: without powers the curse keeping them out of Equestria had been broken, they could traverse the portal at the base of the Canterlot High statue and go back home. The sirens thought they would emerge on the other side in their original Hippocampus bodies, half equine and half fish. Adagio had been positive that when that happened their pendants would be restored, the jewels a natural part of their Equestrian forms. Instead they were turned into three earth ponies, their chest devoid of any magical jewels. And their backup weapons had splashed on their faces.

"It may take months, years, but one day our pendants will have regenerated," Adagio assured, looking into the fire. "and when that happens we can shed this miserable form!”

"I can't wait to have my fins back!" Sonata squeed.

"Our songs will wash over the land, our reign will be absolute!" Adagio rose, her fur bristling.

“We will make Twilight Sparkle pay!” Aria cheered savagely.

“I wonder if her magic tastes like grapes.” Sonata rubbed her chin, licking her lips.

“And then, we will take over Equestria!” Adagio boomed, forgetting her own advice on discretion.

A sinister voice cut through the happy mood, creeping from the surrounding darkness.

“Now that’s something I’ve never heard before.”

The ponies whirled to face the intruder, Aria flopping around like a fish. Sonata thought she could make out an imposing shadow amongst the blackness, just at the edge of the fire’s circle of light. She could see a pair of glowing green eyes, the slitted pupils focused on her.

“Hmmm,” the voice had a strange reverb quality, like the purring of a cat. The shadow sniffed, tasting the air. “delicious, you will do nicely.” Sonata suddenly heard a strange sound, like water dripping from a broken tap.

“Show yourself!” Adagio took a brave step towards the stranger, trying to make herself seem taller. “We aren’t afraid of you!”

“Oh?” the creature tilted its head curiously, staring at her. “Then I will take you first.” The unnerving eyes then sought Sonata once again, making her shiver. “And I will keep you for last.” It purred sensually. Sonata couldn’t help but whimper; she was sure she had seen a pair of sharp fangs, glinting in the darkness. She tried to make herself as small as possible, belly flat on the ground. The dripping sound intensified.

“Come and get us or fuck off then!” Aria challenged, sprawled next to Sonata. The clumsy pony managed to drape a hoof across her frightened sister.

“Such language.” The voice chuckled warmly. “You definitely are not normal ponies. I was right to track your scent.” Once again Sonata was the center of its attention, until someone stepped in front of the shivering girl.

“You won’t lay a hand on us!” Adagio shouted, shielding her sister with her body. “Now begone!”

“Hand?” the stranger sounded confused.

“Yeah!” Aria snorted. “And you can shove a fist right up your…”

“Enough.” The voice lost its seductive tone, and a sickly green magic erupted from the darkness. “Foreplay is nice, but I can only get so hard.”

Aria and Sonata were lifted from the ground, effortlessly carried by the emerald magic. They shouted, cried and cursed, but went silent when their captor stepped into the fading light. Sonata froze as she took in the strange creature, at first thinking that an alicorn had found them. It looked like a very tall equine (even Aria, the tallest of the three, would only come up to her withers) and it was covered in a black carapace covered in cracks and gashes. It had a ragged wispy mane, and equally ragged insect wings. Its wicked curved horn was glowing, illuminating the hungry face underneath. The walking horror licked its lips, covering its ivory fangs in saliva.

“I don’t know what you truly are, my little darlings, but you now belong to me." she cackled evilly, buzzing her wings. "From this day forward you belong to Chrysalis, Queen of the Changelings!”

“Lame!” Aria jeered, spinning in the air.

"Uh?" Chrysalis did a double take, not expecting such a reaction.

"You sound like a dumb Disney villain!" Aria openly laughed

"What's the hay is a Disney?" the changeling murmured in confusion. She wondered if the pony had lost her mind. With the way she had been stumbling like a drunkard maybe she had some brain damage.

“We are no one’s property!” Adagio shouted. She was still on the ground, but her hooves were magically held down. She squirmed to get free. “We are proud sirens, you would do well to release us you overgrown bug!”

“Sirens…” Chrysalis’ eyes widened and for a shining instant Sonata believed that the queen was afraid. But the smile that spread on the changeling’s muzzle dashed her hopes. “I thought that fool Star Swirl had finished the last of your kind ages ago. This is PERFECT!”

“What… what are you going to do to us?” Sonata whispered, her tail tucked between her legs. The hungry stare Chrysalis kept giving her was unnerving. Especially since the slitted eyes kept lingering on her behind.

“Don’t worry my dear.” Chrysalis gently caressed Sonata's face with a tendril of magic. “I won’t hurt you.” She gave the hopeful pony a fanged smile. “Much.” Sonata squeaked fearfully, hers ears twitching as the strange dripping sound got louder, followed by a wet *slap*. She realized it was coming from underneath the changeling... She didn't want to know what she was hiding down there.

“Just try it!” Aria barked as Sonata gave a mewl of distress. “Once we have our old bodies you won’t stand a chance!”

“Then I will have to break you before it happens.” Chrysalis stated matter-of-factly. “Let’s get to it, shall we?”

“You BIT… Hrmm!”

Aria tried to shout, but the magic surrounding them was quickly solidifying, taking the consistency of gelatin. The jelly surrounding Aria’s mouth hardened into a solid muzzle, while she and Sonata where pressed against the wall. The substance started to rapidly spread across the cavern, illuminating the refuge with an eerie green glow. Sonata was too shocked to fight, and soon enough she was stuck into a wall of green goo, her legs covered and firmly held in place. As the cave got brighter and brighter, the rest of Chrysalis’ body was revealed. Her long legs were perforated with holes, her green tail was swishing back and forth excitedly and her fifth leg was beating against her underside in wet *slaps*. Wait, fifth leg? Sonata’s brain short-circuited as she realized what the monstrous member was. A giant black horse cock, complete with a huge set of testicles, the shaft bulging with throbbing veins, the head leaking a syrupy liquid from its jutting urethra; the enormous dick seemed to twitch with the changeling’s heart beat. Chrysalis sauntered over, her eyes fluttering as her schlong bounced against her belly with another *slap*, spraying a long strand of its viscous white liquid on Adagio’s muzzle. The former siren’s hooves were stuck to the ground with slime, her mouth open in a silent scream as she realized what was about to happen. She clicked her jaws shut as the foul smelling fluid dripped into her mouth. The taste was unbelievably potent. It made her gag in revulsion but her body couldn’t help but respond, her nethers becoming hot and moist.

“I thought you were a Queen!” Adagio shouted, spitting repeatedly.

“Oh but I am." Chrysalis purred. She licked her lips with a disturbingly long tongue. "Normally I would oversee the health of my hive, looking over my children as a mother should. They can multiply by themselves after the first generation via ovipositon.” She smiled with nostalgia. “Sometimes I would even take the finest specimens to my bed; only a select few were allowed to deposit their eggs in me.” Chrysalis circled the bound pony like a shark, her member bouncing with each step. “But you see, after some… unfortunate events my hive rejected me. The little brats kicked me out in favor of Celestia.” She snorted with humor. “Good luck to her, they will drive her insane with their whining. Now, do you know what happens when a changeling queen is hive-less?”

“I don’t care about...”

“It’s called the ‘nuptial flight’.” Chrysalis purred, nipping at Adagio’s flanks. “The queen grows male parts and searches for potential mates, ponies with good breeding stock, to create a new generation of changelings.” She stopped behind the struggling pony, sniffing her dripping snatch. It was puffy and wet, a hint of pink quivering under the yellow fur. “Do try to enjoy this.” Her tongue lashed out, thick and slimy. The queen tasted her future conquest, slobbering all over the repulsed pony's backside.

“No! Don’t you dare!” Adagio shouted.

Chrysalis' tongue caressed Adagio's firm thighs, enjoying the pony's squirms of disgust. The changeling raised an eyebrow as her organ coiled around Adagio's teats. They were surprisingly large for a pony, and the thought of the mounds swelling with milk made Chrysalis snort in excitement. A strangled cry escaped Adagio's lips when the wet limb slipped into her without warning. The glistening flat tentacle quivered at her entrance, explored further, tested her depths. It slithered around every inch of her snatch, coiling around like a snake, coating her walls with slime. Seeing the pony wink uncontrollably, Chrysalis smiled and retracted the wet muscle. She seemed to enjoy the taste.

“No wait! You can’t do this…”

“Oh don't worry, I can.” Chrysalis said huskily. “Once my seed reaches your womb you will enter a forced heat.” She growled in anticipation as she reared up. Her barrel collided with Adagio’s shapely rump, Chrysalis squirming impatiently forward. "No need to wait for your natural cycle..."

“That’s not what I meant!” Adagio squealed as the strong black forelegs grasped her sides, embracing her with terrifying power. The changeling was surprisingly light for her size, but her weight still terrified the siren as she was mounted. “NO! We have a destiny…” her breath hitched as Chrysalis’ member teased her opening, the broad head squirting a jet of slimy juice all over her behind. “We have a purpose…” she tried to free her hooves, in vain.

“You have a new purpose.” Chrysalis growled into her ear. “Pleasure me.” Her rear hooves dug into the ground. “Serve the hive.” Her thighs quivered. “Breed.”

The Queen snapped her jaws around Adagio’s neck, ignoring the cries of pain, her fangs almost puncturing the skin. Her hips surged with savage purpose and her back arched; all of Chrysalis' being was bent on claiming her new broodmare. The slick head of her prick pushed against Adagio’s folds, then started to sink in. She hissed in satisfaction around a mouthful of fur, but the opening suddenly got astonishingly tight, her dick popping up and sliding between the pony’s ass cheeks. She grunted, loins burning with need as her dick was squashed between their bodies. Her length seized, veins throbbing as many spurts of goop slathered Adagio’s back, seeping into her poofy mane. Marking the pony in such a way made Chrysalis harder than ever, almost painfully so. This beautiful mare was hers, she would carry her scent inside and out, and before long she would swell with her brood.

Blinded by lust Chrysalis started humping like an animal, her cock ramming into the siren’s groin but never finding her target. Adagio was gritting her teeth with rage as she clenched her privates, trying to keep the dripping shaft out. It slid randomly between her firm buttocks or between her legs, where it slid between her teats. The changeling seemed to linger a little when her shaft was snugly pressed between her swollen mounds, enjoying the pressure before resuming her wild thrusts. Adagio hoped that if she held out long enough the changeling would come from the frantic rubbing. She smirked when Chrysalis started to aim for her jugs more often than her pussy, the queen whimpering in pleasure as her cock squirted all over Adagio's belly. The siren started swaying her hips sensually to make the teat-fuck more pleasurable, Chrysalis hissing at the unexpected action. She couldn't help but halt her humping, letting Adagio massage her shaft. Chrysalis even started to grind her length without pulling back, closing her eyes as she took her pleasure... Before growling in fury.

Realizing that she was being duped, the changeling redoubled in effort, looking to penetrate before she blew her load all over those heavenly teats. She drew back and positively hammered away, although she angled her hips to direct her cock downwards whenever is slipped away. She was about to give in to her pleasure and aim solely for Adagio's belly when one particularly powerful thrust found its mark: the blunt head of her desperate cock pushed Adagio's lower lips open just a bit, sinking instead of slipping away. The siren tried to shy away but the changeling just pressed harder. The turgid length started to bend like a bow as Chrysalis tried to punch through, her nose releasing frustrated snorts, her fangs biting harder, her hind legs straining with effort. She was using all her might to overcome the stubborn mare, she even considered biting her for real… Until the blunt head finally popped into Adagio’s dripping cunt with a disgusting wet *slurp*. The siren screamed in frustration as her walls rippled around the enormous intruder. Above her Chrysalis squealed in pleasure, her whole body quivering as she savored the velvety confines. The queen released Adagio’s nape, a depraved grin on her black muzzle, as she screamed victoriously.

“YES!” the shout was punctuated with a tremendous thrust, her cock barely sinking into Adagio. The length kicked and flexed, spurting slimy jets into the tight cunt, helping it slide in. Chrysalis’ hind hooves dug deep furrows into the soil as she tried to insert herself further. Sonata was looking at the horrible display with tears filled eyes. Chrysalis’ back was to her, so she could see everything as her sister was inexorably stretched. “Keep squeezing like that, I love it!” the changeling cried in ecstasy. Juices were squirting around the massive pole as it jerkily sank deeper, Chrysalis' emissions and her sister's arousal mixed together; they trickled down the siren's thighs and dripped from her drenched teats.

Adagio, for her part, was growing tired and hearing the Queen praise her resistance as pleasurable was the last straw. The siren closed her eyes and accepted her fate. As soon as she stopped clenching her muscles Chrysalis surged into her, the massive length careening into her to the hilt. A great spurt of liquid fired from Chrysalis’ cock as she hit Adagio’s cervix, painting the siren’s insides, coating her already well lubricated tunnel. Sonata held her breath when the translucent slime fired from her sister’s insides, and grimaced once it splattered wetly between her bound hind-legs.

“Coming already?” Adagio snarked. The changeling could take her body, but she would not take her will. If her womb was not breached she could still resist. “Not a very impressive stamina for a queen.”

“Oh, don’t you worry my little slut.” Chrysalis panted with a satisfied smirk. “That was only precum.” She withdrew slowly as Adagio tensed “I’ll tell you when I’m coming.” she shoved her dick with reckless abandon, laughing as she sank balls deep once again.

Chrysalis didn’t care about Adagio’s enjoyment; she was after her own pleasure exclusively. She almost pulled out, leaving only the head, before slamming her hips against the siren’s. Again and again she pounded the abused cunt, her heavy balls smacking Adagio’s swollen teats each time. The changeling felt her twins churn with their load, but she refused to come so soon after being taunted. She would wait until the siren begged for the end. So she sped up, jack hammering away. The sound of her sperm packed balls slapping Adagio's ample bosom was the most beautiful melody she had heard in her long life.

A whimper caught Chrysalis' attention, and she looked back at her two other prizes. Aria was still struggling against the changeling slime, but Sonata seemed to have completely broken down. Tears and snot ran down her pretty little muzzle, her eyes shut and ears pressed against her skull. The sight sent a thrill of pleasure down Chrysalis’ spine, her balls cramping prematurely. To Tartarus with pride, she would have time to deal with Adagio’s disrespect later. Right now she wanted to fuck the beautiful petite blue mare.

“It’s time, little slut.” Chrysalis stated breathlessly. She couldn’t hold on even if she wanted to. “Open up for mommy.” Her balls jumped to her body, her sperm traveling into her body where her seminal fluid was stored. The resulting semen was thick as glue, and it made several visible bulges as it started to travel down her long cock.

Adagio grunted as Chrysalis humped erratically before slamming herself one last time. She cursed under her teeth, wincing, as the head lodged deep within her started to flare. The siren could actually feel the blobs of cum expanding the underside of the changeling cock, slowly making their way to her womb. At this point the flare was obscenely large, spreading her furthest walls apart. Adagio cried out as her cervix was pried open, Chrysalis instantly rushing to press the pointed mouth of her dick into the breach.

“Just for your information” Chrysalis panted, holding her prey tightly, her sperm almost free “this is how it feels like when I cu… Uuuuh”

The rest of her jab was lost as she went slightly cross eyed, pleasure making her mind go blank. Her spunk suddenly rushed from her loins, erupting from her cock in a long and powerful jet. The heavy spurt sprayed into Adagio’s womb, the siren shaking her hips in a vain attempt to dislodge the flared head. Before long she started to feel flushed and weak, her uterus spasming as it was filled. She cursed loudly: she was going into heat while her belly was swelling with spunk, there was no way she wouldn't get knocked up. Chrysalis had won. Tears of defeat rolled down her cheeks as the rush of potent semen tapered out, leaving her with a visible bump on her belly. A few weak spurts later Chrysalis started to slowly withdraw her still flared head, scraping Adagio's walls, making the siren squirm with pain and pleasure. Nevertheless Adagio released a breath of relief, believing her ordeal to be over.

She yelped as the changeling took her mane into her maw. The changeling pulled the orange poofy mane, making Adagio cry out, and brutally humped ahead. The shrieks made her second release much more pleasurable. And the cycle repeated. Every time the flood of spunk subsided Chrysalis retreated, almost pulling out of Adagio’s cunt. She waited for a random amount of time, letting Adagio wonder if she had finished, only to furiously yank her mane and ram her cock into her, the gaping cervix accepting another helping of thick spunk as the pony screamed in pain. Her balls were still fervently producing the potent mixture, her whole body focusing on delivering it into the fertile pony.

Chrysalis didn’t know how long she kept filling her broodmare, but after some time she could no longer hilt, her own dense emission halting her thrusts. She exhaled deeply and stilled her hips, feeling the last of her cum travel down her length. Her flared cock deflated, but before she was completely soft she gave one last playful lunge, packing her spunk as deep as she could with an audible *squish*. Her cock then slipped out noisily, the organ dripping like a faucet as it swung limply. Chrysalis ignited her horn, healing Adagio’s insides and resealing her cervix, trapping gallons of spunk inside her womb. She took a step back, admiring her work.

Adagio had a haunted expression, tears matting her fur, but she still had a fire burning deep in her eyes. Chrysalis smiled happily. She was glad Adagio still retained her personality even after such a rough fucking. A dead minded mare was no fun to mate with in her experience. The former siren was bloated with her sperm, the excess trickling slowly from her restored pussy in heavy clumps that splattered between her trembling hooves. Her generous jugs were reddened after being bludgeoned by Chrysalis' balls repeatedly, trickles of sperm running down their mouth watering curves . The changeling pinched a nipple with her magic and twisted, enjoying Adagio's wince then, unable to resist, Chrysalis rushed forward, bent down and took one of the fat mounds in her mouth. Taking special care with her fangs Chrysalis suckled urgently, her tongue grasping the nipple, stretching it, milking it... She couldn't wait for Adagio to start lactating! For now her suckling only tasted like her own spunk. The scent of sex was overwhelming, making Chrysalis’ soft cock twitch. Her jaw unhinged wider, trying to swallow the whole thing as Adagio moaned despite herself. Chrysalis started to day dream about mounting the siren while their newborn children crowded under them to nurse, the little changeling foals slurping her milk while her cunt was ravaged. She put the thought away for later as she reluctantly released Adagio's teat with a *pop*, her tongue giving it one last squeeze.

“One down, two to go.” She sang as she turned to her next victim. Aria looked livid, her eyes promising murder. "Don't look at me like that, I promised your sister would be last." she chuckled darkly, her horn glowing.

Explosive Decompression

Adagio was plucked from her restraints and floated towards her sisters. The exhausted pony offered no resistance as she was pinned to the wall, her body sinking into the green slime. Chrysalis made sure her inflated belly was well supported; she didn’t want anything to happen to her children's breeding ground. With the way her womb had been stretched Chrysalis expected the siren to foal at the very least a dozen changeling-sirens hybrids on her first term. But in the end it depended on how many eggs Adagio’s ovaries had released when she entered her unnatural heat. Usually ponies would only carry one or two foals, but changeling young were smaller, she would have no issue gestating Chrysalis’ brood. Although she may have some problems with birthing them; Chrysalis looked worriedly at the siren’s hips, they were a little too narrow for her taste. It certainly had felt that way when her cock had stretched her insides. And there was one other siren that was even smaller.

Her gaze was drawn once again to the smallest sister, Sonata. She wasn’t the sexiest pony she had ever seen (that title belonged to a certain white alicorn she dreamed of breeding one day) but she certainly was the prettiest. The azure pony stirred something in Chrysalis, and not only her loins. Usually the perverted changeling's gaze was drawn to buxom females, ponies like Adagio with her magnificent jugs or Aria, with her wide birthing hips. She was a creature bent on breeding after all. But Sonata was different. Her diminutive stature and soft curves were strangely appealing in her opinion. Her lithe flanks were mouthwatering, with just enough meat to be firm. Her fur was perfect, shinny and soft. Even her little squeals of fear were titillating. And her features...

Chrysalis felt herself swoon. Sonata had the most inviting little muzzle, with a profile you usually only saw in museums, etched on antique statues and busts sculpted from the purest of marble. Considering sirens were immortal, like changeling queens, it was a real possibility that she had modeled for some of them, if her siren form was as beautiful as this one. Her cute pouty lips were full and glossy, begging for a kiss the changeling was dying to give. She had a delicate pointed nose, framed by a pair of alluring sexy lavender eyes with long and curved eyelashes. She was simply gorgeous. The perfect mate. The purest most innocent creature the long lived changeling had ever laid her eyes on. She couldn't wait to cover her exquisite face in spunk, let it mix with her tears, before licking it off sloppily.

Chrysalis' tongue quivered in anticipation. This one would have a special place in her hive. Chrysalis could feel herself harden as she considered never shedding her male genitals after the first few waves of changeling hybrids were born; like she had done ages ago. Like her predecessors had done since the dawn of time. Instead she could have Sonata every day, increasing exponentially the size of her hive instead of waiting for her children to multiply by themselves. This went against the natural order, but that only made it more desirable. Two immortals, locked in an eternal mating frenzy. Her sisters would have to be kept alive to make sure she remained happy, but that could have its benefits. They could be given to their own children as egg incubators for example. Or she could use Adagio's fun bags as pillows. Speaking of which, Sonata's teats were small and firm, her nipples just a shade darker than the rest of her fur. Chrysalis couldn't resist rubbing her snout against the little mounds.

Sonata whimpered when Chrysalis nuzzled her belly, wiggling to escape the touch. The changeling took the rejection in stride; she had time to work on their relationship. Relationship? Chrysalis had never thought about her interactions with anyone as relationships. She idly wondered if this was love. The fluttering in her dark heart whenever she looked the siren in the eyes. The desire to brush her mane, playing with her ponytail. The irresistible urge to shove her dick in her snatch, make her scream in pleasure and agony, watch her balloon with her seed, cover her in semen until she couldn't remember the color of her fur… Yep, definitely love. Maybe she would ask Cadance for confirmation when they met again: they could have a nice chat around tea and biscuits while the Princess of Love was speared on her dick. Oh, she didn't hate her: the pink bitch had thwarted her plans, but her hate was reserved for another alicorn. Chrysalis was just curious to see what hers and Cadance's offspring would be capable off. But that was for another time.

Chrysalis considered the last sister, Aria, the muzzled pony still glaring daggers at her. If she followed the list she was next. The purple siren would be a fun ride too, her ample flanks looked deliciously well toned, but she was not as appealing as her little sister right now. She had given her word Sonata would be last. But then again… maybe she could indulge a little. Just a little. The changeling’s magic took hold of Sonata’s face, making her look into her green slitted eyes. She smiled, trying to appease the panicked pony. It worked somewhat: at least she wasn’t crying anymore. Very carefully Chrysalis brought her muzzle to her ear.

“Do you remember when I said I would take you last?” Chrysalis whispered gently. Sonata nodded with relief, her eyes flicking to Aria with an apologetic grimace. She was worried about her sister? How precious. Time to reassure her. Chrysalis buried her snout in her mane, inhaling deeply before purring “I lied.”

Sonata’s eyes bulged in realization. She started to struggle and opened her mouth to scream. Chrysalis took the occasion to plunge her long wide tongue down her throat, closing her jaws around her delicate lips in a horrible mockery of a kiss. To Sonata’s horrified sisters it looked like Chrysalis was trying to swallow the small pony whole, just like a snake. The changeling reveled in what she perceived as a romantic moment, exploring her partner and enjoying her reactions. Sonata kept squirming under her grasp. She began to squeal in fear whenever the changeling’s razor sharp teeth scraped against her blunt pony dentition. She tried not to move when the needle like fangs grazed her fur. She dry-heaved as she started to choke on the fat oozing tongue still thrashing in her throat. Her tears ran freely down her puffed cheek. Everything she did made the changeling’s heart soar. Chrysalis’ cock was twitching madly with need, but she wanted to make the passionate moment last. For now she contented herself with beating her cock against her barrel, her length already leaking in anticipation.

Before long Sonata’s eyes started to roll back, her air supply exhausted. Just before she could slip into blissful oblivion the psychopathic changeling released her prey, her lengthy tongue slithering out noisily. The pony greedily inhaled, coughing on Chrysalis’ abundant drool. Meanwhile the changeling was happy to wait, cooing as she licked Sonata's tears from her cheeks. Everything about the little pony made Chrysalis unbearably hard. Her green eyes followed a stray drop running down the siren's cheeks, flowing to her neck. Captivated she leaned in, rubbing her nose on Sonata's collar, breathing in her scent; the scent of prey. Unable to stop herself she suddenly snapped her jaws around the siren’s slender neck, her deadly fangs sliding safely on her nape. Adagio held her breath, thinking that Chrysalis was going in for the kill, and looked away with a sob. Aria yelled in fear for her sister's life, her desperate screams muffled by her muzzle, trying with all her might to break free. Chrysalis whined softly as she felt Sonata gulp; the siren was deathly afraid, arousing the changeling’s predatory instincts. She couldn’t help but bite a little harder, her sharp teeth sinking into her coat without puncturing it. Chrysalis held on, leaving a lasting impression of her wolfish teeth on her mate’s neck. After what felt like an eternity to all the sirens, the changeling opened her maw, staring proudly at the bite mark on Sonata’s neck, a lasting mark of propriety.

Satisfied, her cock bounced against her stomach once again and she was astonished to feel her flare had already begun forming; flaring while outside of a mate, that had never happened to her before. Chrysalis had no intention of wasting her seed on the floor, not to mention embarrassing herself in front of her love. She freed Sonata’s hooves, intent on mounting her as fast as possible, but she had to jump away as the pony started flailing around in a panic, a buck just missing her black muzzle. The motion caused her balls to collide painfully with her thighs, making her grunt. The fat orbs began to constrict and pull up: she was out of time. Sonata found herself back on the wall, her legs stuck spread-eagle like before, but this time the changeling reared back and pressed herself against the bound pony.

Chrysalis’ back hooves shuffled drunkenly on the ground while her fore-hooves rested lightly on Sonata's shoulders, her wings buzzing desperately as she sought her equilibrium. Sonata didn’t understand what the changeling was trying to do until she felt something horribly hard and wide collide with her nethers. Looking down she saw the giant black dick kissing her privates, head glistening. She almost fainted right on the spot. Chrysalis’ cock was already larger than any normal pony, but without being constricted her flare had grown monstrous, its girth twice as wide as her shaft. It was so hard that it forced Sonata’s thighs apart, the restraints on her hooves stretching to accommodate her new position.

“I’m sorry my love.” Chrysalis’ honeyed words chilled Sonata to the bone. The changeling was staring at her with a dopey expression, a terribly sweet smile on her muzzle. She had seen that look before: when she was putting someone under her spell. The idea of this crazy monster having special feelings for her made her heart drop in disgust. “I couldn’t help it, I just want you sooo baaaad.” The changeling’s repuslive tongue leaped at her, coating her muzzle in ooze. Sonata clenched her jaw shut, refusing to let it into her mouth even when the tentacle pried her lips open. It retreaded after covering her clinched teeth in gunk. Sonata had no time to celebrate her small victory; she squirmed as the flat cock pushed against her little opening. There was just no way it could enter her, but it seemed Chrysalis had other ideas. “Don’t move, I don’t want any of it to go to waste.”

The changeling heaved, her dick pressed firmly against Sonata’s pussy, her green magic surrounding the shaft to hold it steady. The pony wondered fearfully what her captor was planning until she felt something slip between her lower lips. It was small and round, like one of those horrible tampons she had to use as a human, but shorter. What was that… She gasped when a terrible warmth started to spread inside her. The flared head was quivering, delivering a heavy load that splattered directly into her unused cunt. The changeling had pressed her protruding cock hole directly into her tight opening; she was being filled with thick changeling cum.

Sonata tried to scream but once again Chrysalis took the open mouth as an invitation for her trademark nightmarish kiss. Only this time the flat tentacle didn’t go down Sonata's throat, it was content on wrestling the small pony tongue into submission. She squirmed and hollered into the changeling’s maw, to no avail. The cock down below was still pumping incredible amounts of jizz into her pussy, the spurts powerful enough to blast the seed right against her cervix. Thankfully the barrier stayed firmly contracted, not letting any unwanted sperm past. But the spunk still pooled inside her, stretching her velvety walls painfully.

The flared head stayed pressed painfully against her honey pot, preventing any spills, until the pressure was too great: Sonata's small cunt couldn't expand like a womb, and the sticky seed started to spray from her lips, splattering her thighs and Chrysalis' abdomen. Yet the changeling still didn't stop cumming, her tongue wiggling in the siren's mouth, and she just ground here cock harder. Sonata’s jaw started to feel sore from the kiss, and she wondered how long this could go on for.

A few minutes later Sonata cried out in relief as Chrysalis released her mouth, but kept pumping into her over-stuffed cunt. Every spurt was now accompanied with a shudder from the changeling, a glance to her face explained why. Chrysalis seemed to be exhausted, her eyelids dropping as her tongue lolled about limply; she had hoped Sonata's cervix would open under the pressure, but the blue pony didn't show any sign of being in heat, and her precious spunk was escaping around her dick, splashing her belly. The changeling's hips shook with frustration, wishing she could just penetrate her mate. A few erratic jerks misaligned the flared head, and Sonata was promptly covered in strands of thick royal jelly. The stuff clung to her fur like glue, warm and dense, the smell making her head spin. She tried to only breathe with her mouth, but a gooey strand chose to land directly into it, making her gag.

Meanwhile Chrysalis took in the sight of her love covered in her spunk; in her twisted world views this meant that the blue pony was hers, body and soul. She owned this lovely mare, and next time she got around to fuck her she would do it right. The thought caused her balls to seize, her cock kicking as a powerful jet of cum blasted against Sonata's chin, spraying her hapless sister's in the process. Soon the surge tapered, and with a sigh she released her last pent up jizz, the weak spurt landing wetly on Sonata’s small perky teats.

The flare started to subside, the length growing soft as dribbles of semen escaped Sonata’s cunt. The siren sighed in relief and worked her lower muscles, trying to expel as much as she could. Chrysalis was disappointed as the dribble turned into a torrent; so much wasted seed. Looking up from the tragic loss, she took in Sonata’s red face, her eyes clenched. She mistook the siren’s look of concentration for one of grief, and trying to console her mate she moved her flagging cock to plug at least some of the wasted load.

It was with great surprise that the head of her dick popped inside Sonata with barely any resistance. She and Chrysalis stared at each other for a few instant, their shocked expressions comically matching. Between Sonata's attempts at opening herself up and the stretching she had received, her cunt was wide enough for the flared but slightly soft head to penetrate. Chrysalis realized she could still salvage this session, her dick starting to harden, and Sonata knew in her heart that she was doomed. The changeling muzzle stretched into a predatory grin, while the pony closed her eyes in acceptance. Chrysalis started to thrust slowly, her cock still a little soft but quickly thickening. She inhaled Sonata’s scent, blended with her own. She thought about their future children, thought about the still dry womb she had to water, and finally said a single word.

“MINE!”

Her cock sprang to life in a heartbeat, stretching the small pony painfully. Sonata winced and wept quietly, her distress unnoticed as Chrysalis only concentrated on impregnating her mate. Her balls still needed a refill and would not be ready to fire without some rest, but Sonata was already carrying more than enough in her stretched cunt. She would not be bloated like Adagio had been, but it suited the queen just fine. It would preserve Sonata’s appealing physique, if only temporarily. Chrysalis pumped mechanically, only inserting the head and a little of her shaft. She didn’t want any of the stored spunk to escape around her cock. Needing just a little push for her flare to grow completely hard, Chrysalis searched for Sonata's marvelous eyes, only to find them closed.

“Sonata?” Chrysalis hesitantly asked. The pony opened her eyes, but the changeling saw so much sadness and hurt in those orbs that she halted her shallow thrusts. She didn't even notice as the siren's eyes shone with power, a red twinkle blinking in and out of existence on her chest. A seed of doubt started to grow inside the usually uncaring changeling, her cock deflating rapidly. Did she hurt the pony she loved so badly? Had she been hurting her from the start? Did Sonata hate her? Why did Chrysalis care? Why did she care so much! The more she doubted herself, the stronger the red light shone, starting to solidify into sharp jewel.

Sonata for her part was tired of it all. Her hips were sore from being stretched apart, her lower lips felt raw from the rough prodding, and her pussy was almost too small to accommodate Chrysalis’ giant cock. She just wanted this to be over. She looked at the confused queen, thinking that the changeling was looking for a way to finish in a spectacular fashion, and decided to help her along the way, if only to be free of the alien presence down below.

Chrysalis was lost in a spiral of self realization about all the foul deeds she had committed when Sonata moaned loudly, the changeling gasping as her mate wiggled her hips. Chrysalis stared, not understanding this change in attitude. The siren’s eyelids fluttered, her gaze turning sultry. The changeling’s cock hardened. Sonata licked her lips. The head started to flare slightly. Sonata opened her mouth, letting her tongue out with another sensual moan as her eyes rolled back. The flare exploded, mushrooming out of control. Chrysalis carelessly destroyed any semblance of self doubt from her mind, her introspective thoughts forgotten forever. All that mattered was that Sonata wanted her. She wanted her cock. She wanted her children. And Chrysalis would not make her wait. The red jewel dimmed, sinking into the siren's coat, unnoticed by all.

Chrysalis kissed Sonata fiercely, but this time the small pony responded in kind, her tongue darting into the changeling’s mouth. The queen whimpered in happiness, carefully guiding her lover’s tongue away from her dangerous teeth. With a triumphant heave she thrust her flared head into Sonata’s love tunnel, catching all the remaining semen and pressing the sticky mass against her cervix. As the pressure made her last barrier crumble, Sonata lost herself in the slobbering kiss, forgetting for an instant with whom she was sharing it. She just tried to enjoy the horrible moment, and even began to appreciate the way Chrysalis’ cock distended her belly, the flare clearly visible under her fur as it battered her insides.

When the first drops of cum dripped into her womb, she disengaged from the kiss and cried in pleasure. Chrysalis joined her an instant later as the flared head was sheathed one final time. The wall of spunk was compressed against the siren’s wall, building pressure before popping her cervix like a cork on a bottle of champagne. The thick sludge gushed into her womb in an impressive display of explosive decompression, splattering powerfully against her internal walls. Chrysalis squealed in happiness when her flare kissed Sonata’s open cervix; her balls churned desperately but she could only fire a measly pint into her lover, the load traveling lethargically down her shaft before it plopped sluggishly into Sonata’s womb. Not realizing that her emission was very much respectable in comparison to a normal pony, Chrysalis vowed to make it up to her lover next time. Maybe by filling her up to her limit, then draining it all out, before stuffing her once again. That sounded like fun.

Panting, Chrysalis tried to extract herself from the intimate embrace, but her hooves slipped in the puddle of wasted cum and she fell on her ass. Sonata screeched as the flared head rushed out of her, seeming to pull her insides out. But before she could begin to feel any more pain a soothing sensation took away her discomfort. The siren peeked fearfully at her belly with her tear filled eyes, surprised to see it glow with an emerald shine. She turned her gaze to the sprawled changeling. Chrysalis was staring up at her with the look a prisoner gave the sky after decades of dungeon life. Her magic was working away at healing her mate, her limp cock lying in a puddle of her own jizz. The flash of green siren magic was lost amongst her equally green eyes.

“You are mine, forever.” Chrysalis said with her awestruck expression still intact. "Mine." Her twisted version of love was making her heart flutter. As far as she was concerned they might as well have just exchanged vows, their union sealed and consumed.

Sonata didn’t know what she could say to avoid enraging the demented changeling, but it seemed that Chrysalis didn’t care. Sonata's hooves were freed, her body carefully lowered to the ground; the crazy changeling even took the time to brush a wild strand of azure mane out of her eyes. Sonata was confused by the gentle treatment, and her heart stopped as Chrysalis threw her hooves around her head. Sonata shuddered: the changeling was leaning in for a kiss. She prepared herself for another traumatic experience, squaring her shoulders. But this was not the fang-tipped, jaw-unhinged-like-a-snake, tentacle-tongue-trying-to-tickle-her-stomach smooch that she had expected. It was just a quick closed-lip kiss, Chrysalis’ surprisingly soft lips brushing against her own. The gesture was so chaste (especially in comparison to what had just happened and the fact that she was standing in a puddle of pungent gooey spunk eeew) that Sonata's brain just gave up, shutting down. It almost made her miss the weak pull of magic that linked her to the changeling. She squeaked in surprise, testing her magic. It was fragile, but it was there. Somehow Sonata had managed to put Chrysalis under her spell. Now all she needed was to strengthen their connection.

As Sonata gazed at the infatuated queen she realized three things. One: the changeling was crazier than a bunch of raccoons high on crystal meth. Two: she seemed to genuinely care for her, and that meant that there was a nugget of good under all her crazy rapist exterior. She could use that unexpected weakness to her advantage. And three: if she could get Chrysalis totally under her control she would be a great benefit towards the sirens’ goal of taking over Equestria. Although if she wanted to avoid having her little pussy destroyed by the sex crazed changeling again and again she would have to play it smart. And that meant she needed her sisters’ help.

Sonata smiled confidently. She was a siren. She and her sisters excelled at manipulating all who fell under their spell. And Chrysalis was definitely under hers; without even having to resort to her singing the changeling had fallen head over heels. Since Chrysalis was so obsessed with her, Sonata was ready to give herself willingly to ensure Adagio’s and Aria’s well being, but she was sure it wouldn’t be necessary. With Chrysalis so lost in lovesick wonderment and her siren powers awakening, how hard could it be to make the changeling promise to never hurt her or her sisters again? It should be a piece of cake to turn the once proud queen into an ally, and before long Chrysalis could be bowing to her every command. She would have to be the most incompetent siren of all times to screw this up.

…

Ooooh boy.

Mid-Air Refueling

Sonata had never been considered to be the brightest of her siren sisters. Some would call her charmingly simple; others would say she was dumber than a sack of bricks. She certainly felt like it at the moment.

"and Aria is really not that hot anyway, I mean have you seen her face? I mean yeah, she's really tall and has great legs, and some really nice big hips but... I mean horrible, just horrible! Having sex with her would be a huuuge waste of time." Sonata rambled, sweat running down her brow.

Her plan had been fool-proof: sing, assert her control on Chrysalis, release her sisters, use their combined powers to enslave the changeling completely, take over Equestria and make some Twilight Tacos. Easy! Except her chant had alerted Chrysalis, the changeling’s mind steeling itself before Sonata could get to her. The tenuous link to the queen’s mind had been severed instantly, and her beautiful song had turned into the horrendous braying that was her natural singing voice. Using her siren powers without feedback from Chrysalis’ self loathing had exhausted her limited supply of magic. Without her powers Sonata could only try to use her head to convince the changeling to let her sister go unharmed, and that had never been her forte.

"Don't get me started on Adagio! Look at that hair, it's like someone blew up firecrackers in it; I'm sure you're not into ponies with fluffy hair like that. Or are you? You did play with it when you were stuffing her. Sure it's nice and soft, and her rack is huge even as a pony but..." she gulped, cursing her wandering attention span. Right now Chrysalis was staring at her, her head tilted and ears perked. She looked like someone witnessing a never ending train wreck. She peeked back at her bound sisters to ask for support, but only found an exasperated Adagio and an infuriated Aria. Nothing new there. "I mean, it's not like I'm saying that we want to escape or nothing, I just think they need to stretch their legs, catch some fresh air, run a few miles...."

“Of course you won’t escape, I trust you completely my dear.” Chrysalis suddenly beamed. The siren breathed a sigh of relief; it seemed the changeling had not realized what she had tried to pull… "And by now the exit has been sealed with my changeling resin, so you can’t get out without my permission, you little traitor.” Sonata’s heart skipped a beat as the changeling smirked knowingly. She was so busted! The crazy changeling knew she had tried to brainwash her! She had been utterly wrecked when the changeling was trying to be gentle, could she survive whatever Chrysalis considered angry sex? The changeling's horn ignited and her muzzle turned into a fang filled smile. Yep, doomed. She guessed she was about to get very intimate with mister tentacle tongue any moment now...

“Thanks.” Sonata almost jumped out of her fur when Adagio spoke from her side, standing on unsteady hooves, rotund belly swaying obscenely. The golden siren looked pointedly at her sister. “Isn’t Queen Chrysalis nice, choosing to release me? Eh Sonata?” Adagio’s left eyebrow wiggled three times, the signal for speak up, you look like an idiot. Or was it two times for shup up, you look like an idiot? It was hard to tell with all the congealed spunk clinging to her face. “It’s good to see she trusts you so much, you two make such a lovely couple… HmmMMMMM?” Definitely three wiggles now.

“Oh yeah!” Sonata put on her best smile as she turned to a smirking changeling. “Thanks a bunch! You’re the best rapey… I MEAN HONEY! Sweetie? Dear? Chryssi?” Sonata tried desperately to shut her mouth, and she distinctly heard Adagio face hoof. It was clear Chrysalis wasn’t buying it either, but at least she was still smiling. Sonata couldn’t help but blurt out one last idiotic line. “My love?” Even Aria voiced her opinion, her muffled mumbling clearly scathing. Sonata eeped as the changeling chuckled.

“You are lucky I want you so much.” Chrysalis considered giving the pony a demonstration of just how much she wanted her, but her tongue was still sore from over-use. “The last creature that tried to control the mind of a changeling queen with a song paid dearly, as did his race. Poor satyrs.”

“Satyrs? Never heard of them…” Sonata said cheerfully, her smile strained.

“Exactly.” Chrysalis purred, grinning dangerously. Sonata gulped and backpedaled until her rump hit the wall.

"I'm guessing we can dispense with the double talk then?" Adagio deadpanned. Unlike her little sister she took a step forward. Her belly sloshed noisily as she fearlessly approached the sitting changeling.

"Careful little slut." Chrysalis warned, her face darkening. "Do not think that you have the same status as my Sonata."

"Of course not." Adagio responded with a haughty tone. She stopped a step away from the queen. "I know I am not as 'special' as our dear Sonata."

"MY Sonata, MY mate." The changeling hissed, pressing her muzzle against Adagio's.

"And my sister." the siren didn't back down. "Like it or not, if you want Sonata you'll have to live with me and Aria. And I am willing to make a deal."

"Fine." Chrysalis' magic took hold of the siren, turning her upside down as she was hoisted like a piece of meat on a hook. The changeling leaned back on her haunches and frowned at the dangling pony. "Here's my proposition. Carry my brood, serve the hive, shut up and be happy I don't break your mind." she noted idly that Adagio's teats looked lovely from this angle. Her soft cock twitched as it remembered being trapped between them. Something that didn't go unnoticed by the floating pony.

"No." Adagio's smirk was infuriating. "We all have things the other wants" the siren closed her thighs, pressing her teats together in a very stimulating display "there's no need for us to be enemies."

"Whore..." Chrysalis spat. She cursed her cock for beginning to rise.

"I see it as using every advantage I can get." the siren jiggled her mounds, snickering as the black cock jerked in response.

"I won't let you go, if that's what you want." Chrysalis warned. Since her black cock had already betrayed her attraction, she might as well indulge. She surrounded her shaft with an emerald glow, letting her magic solidify into a green cock-sleeve. She began telekinetically stroking it slowly. "I'll admit that you have some... 'assets' that interest me." She gave her growing dick a powerful squeeze, making the head swell for an instant. "But that only means I am even less inclined to release you."

"And what if you could claim these assets freely." Adagio used her forehooves to pinch her dark nipples, giving the queen quite a show. "You could have this," she slapped one of her teats gently, the changeling's cock doubling in girth instantly, fully rigid "without having to restrain me."

"What do you want." Chrysalis groaned reluctantly, her whole attention centered on Adagio's erect nipples.

"To be treated as allies, not prisoners.” Adagio pulled her fat udders in opposite directions, before letting them slap back together. “We are not holes waiting to be filled, respect us and I will personally please you whenever you want. "Adagio covered her mounds with her hooves, the teasing making Chrysalis' breath hitch. "One last thing: give us the assurance that you will help us get our revenge on Twilight Sparkle." As soon as she said that name the changeling's cock bulged obscenely. Chrysalis let her telekinesis falter as she grabbed the cock-sleeve with her forehooves and went to town. If there was one pony she wished she could ravage with particular savagery, it was Twilight. "I'm guessing that's a yes?" Adagio snorted, a smug grin on her face.

Chrysalis considered her options as she stroked herself furiously, dreaming about the lavender alicorn screaming under her. Normally the three sirens should have been broken, either spiritually or physically, but her attraction to Sonata once again made her reconsider the old changeling ways. Adagio wanted to be an ally, an interesting idea; sirens and changelings were very complementary, one feeding on animosity and the other on love. If their offspring inherited both abilities they would be the most powerful breed yet conceived, but they would also need teachers to master their new powers. So be it, the sirens could have some of their freedom back in exchange for their cooperation. They would remain her sexual toys, of course; Chrysalis had never been serviced willingly by a pony, and she was impatient to see what Adagio had in mind.

“You three are free to do as you please, even leave this cave if you want.” The changeling decided to compromise, at least for now. “But I will always keep at least one of you as insurance. If you are gone for more than a week, I'll hunt you down, bring you back and our deal will be over. In preparation for my… our children's arrival I will be busy building a temporary hive in the underground, so I’ll need some comfort.” She licked her lips, eyes traveling to Sonata. “And I want to enjoy your bodies as they are now, so no transforming into sirens when your powers come back. I'll tolerate wings, but I have no taste for fish.”

"Fine." Adagio agreed. They would still be able to project their true forms when necessary anyway. She stopped playing with herself as Chrysalis' attention turned to her sister. "But remember this: we will be powerful again one day, and if you hurt my sisters..."

"Oh I'm sure you'll try to fight me." Chrysalis seemed excited by the idea, pumping faster as her gaze devoured Sonata whole. "But by that time you won't be able to live without my cock, little slut." A squirt of precum landed on Adagio's impassible muzzle, the siren not even flinching.

"I doubt it." She deadpanned.

"How about this" Chrysalis looked back to Adagio, smirking. "I will try to hold back whenever I take you or your sisters, and I do mean try" another well aimed squirt "and I won't punish you for fighting back. Deal?"

"Deal." Adagio nodded, already planning on ways to make the queen pay for what she did.

The siren knew Chrysalis was aware of her mutinous thoughts, and the changeling clearly was aware that she knew. The two opponents smiled, the challenge recognized, both sure of their own eventual success. If Chrysalis thought that she couldn't fall completely under their spell, Adagio would just have to show her what sirens were truly capable of working together. The telekinesis holding her in the air shifted and the siren was carefully lowered to the ground. She rolled her eyes and clicked her tongue impatiently as Chrysalis started to magically fondle her udders; it seemed the perverted changeling just couldn't help herself.

“Hmm.” Sonata hesitated, not sure on how strong her pull on the queen really was. She was also a little unnerved at seeing the changeling grope her sister. “If I promise to be your... lover, willingly" that got Chrysalis' attention, she even stopped jacking off to stare at her hungrily "can you promise not to touch my sisters anymore?” she squeaked uncertainly. Adagio shot her a surprised look, a hint of gratitude in her eyes.

“I will consider it." Chrysalis murmured. She released Adagio's jugs, a massive yawn making her jaw unhinge (to Sonata's great horror). She needed a nap. But before she could rest she had to take care of her mates. "Both of you follow this tunnel.” Chrysalis nodded to the path leading to the underground. “You will find a pond of spring water there, wash yourselves.” She frowned. “And know that my consciousness is linked to my magic.” She warned, pointing to the green muck covering everything. “I know about all that goes on between these walls. Try to harm the children growing in your womb and I will know.” She threatened, looking specifically at Adagio."Now go."

“What about Aria…” Sonata squeaked.

“As I said, insurance.” The dismissal was clear, the sirens shooting their bound sister one last look before departing. As Sonata and a wobbling Adagio were about to disappear around the bend Chrysalis called them. “And I will accept you calling me ‘your love’.” She smiled as Sonata froze in place, only to be yanked out of sight by her inflated sister. It was strange; she knew the petite siren didn’t care for her like she did. Chrysalis had instantly realized when Sonata had tried to use her feelings to manipulate her, yet the changeling wasn't furious about it. Maybe Chrysalis took it as a challenge. Maybe love was a thing that surpassed even her own fury. Maybe she was changing. Or maybe she just didn't care as long as she could tap that perfect blue ass for the rest of times. A muffled snicker caught her attention. Aria was openly laughing at her, her cum splattered body shaking with mirth. Chrysalis’ horn ignited, and the pony was suddenly freed. She fell in a graceless heap, but still found the strength to grin mockingly.

“Never seen a villain fall in love before.” Aria tried to stand, only to stumble on her ass. “It’s pretty pathetic actually.”

“You are going to abuse Sonata’s request that I don’t touch you, aren’t you.” Chrysalis said dully, before yawning again. She turned her tired eyes to the walls, her horn glowing.

“Yep.” Aria beamed. “You fuckwit.”

“What makes you think I won't rip out your insolent tongue?” Chrysalis asked lethargically. She concentrated on manipulating the green goo, stretching a solid rope across the cavern path. The changeling then widened it, sculpting herself a comfortable place to take a nap.

"Cause you are a big fucking softy apparently." the siren snickered. “Vanquished by a pair of boobs.”

"You have a big mouth, you know that?" Chrysalis clambered on her improvised hammock, lounging on her back with a sigh, her cock standing like a mast. She let her hind-legs dangle lazily and crossed her forehooves over her chest.

“So what is it like, being Sonata's bit… HEY! What the fuck are you doing!” Aria screeched as she was levitated over to the smirking Chrysalis. “Wait don’t! You BIT… GLURK!” Aria’s taunts were suddenly trumped by the best response Chrysalis had to an insult: a big cock down the throat.

“Aaah.” She sighed as her magic forced a flailing Aria down her dick. “That’s better.” She felt too tired to move, and decided to let her magic take charge. The gurgling pony was impaled until her chin touched her balls, her hindlegs held in the air. As promised Chrysalis didn't stop Aria as she struggled to free her windpipe: the siren grasped the solid shaft with her forehooves and pushed herself up. It was like an hilarious reverse of trying to climb a rope; if you were trying to swallow the rope while you climbed that is. After a few minutes of desperate struggle, the large head slid free from Aria's mouth, saliva dripping everywhere. "You know, I never did promise I wouldn’t touch you two." Chrysalis said matter of factly. She kept the panting siren suspended over her, slapping her slimy cock all over her reddened face. As soon as the siren caught her breath she was forced to swallow the huge shaft once again. "Oh and keep biting, it only makes it better.” The changeling closed her eyes peacefully as her cock distended the siren's throat, her retching and gagging lulling her to sleep.

The game kept repeating until Aria couldn't push herself up anymore and had to wait for Chrysalis to levitate her. Of course the changeling waited as long as she could, the siren almost passing out in the process. The queen had to admit that it was quite relaxing to lay back and let her magic do the work. She opened one of her eyes, and was pleased to see Aria staring back with an infuriated expression, her reddened tear filled eyes quivering with rage. She still had the head of her cock in her mouth, having to breath through her nose, but she made up for her muteness by trying to chomp down wolfishly on the offending organ, to Chrysalis' pleasure.

“I’m sure Sonata will understand I can't keep my affection just for her, that would be selfish." Chrysalis snorted, giving a little reflexive hump of bliss as the siren chewed on her dick. " I do have an empire to sire after all. Speaking of which…” She lifted Aria up, her cock popping out of her mouth with an incredible quantity of saliva strings still connecting them. The visible teeth marks on her shaft and head made Chrysalis pause. She was used to mark her mates, but this was the first time she had ever been marked; never before had anypony staked their claim on her body. She expected to be mad, but it just made her hornier. If this was a battle for dominance, she would do everything to come up on top. She flipped Aria around, held her hind legs apart and dropped the gurgling pony on her massive cock.

“YOU BITCH!” Aria roared as the massive shlong battered her insides.

“Oh, finally got that out of your system?” the changeling grunted, savoring her new conquest. Chrysalis stared at Aria's mane, the twin ponytails thrashing as the pony cursed up a storm. She had thought that if she took the noisy pony from behind, closed her eyes and tuned-out her prattling, she could have dreamed she was fucking Sonata; but alas, her walls were not as velvety; they were rougher and more muscled. Not too bad actually. Wanting to finish quickly and go to sleep she started to jerk the purple pony up and down like she was nothing more than another cock sleeve, waiting to be used. She had never fucked a pony that had the gull to talk back while she took them, and she had to admit that the constant barrage of insults was kinda turning her.

“and I will shove your fucking horn up your fucking ass before putting a fucking shotgun up your fucking cunt and blow the fucking trigger!”

Yep, this was working for her very well, even if she had no clue what a shotgun was, and her head was already starting to flare. Probably feeling her cock expand, Aria took it upon herself to contort as much as she could, twisting her length painfully. Chrysalis admired her spirit, wondering what would have happened if she had tried to shag the wild pony without her magic. She was curious to see if she could even manage to mount her... Her lewd thoughts brought her very close to the edge, her flare very sensitive after the rough treatment in Aria's mouth. She began to bring the siren down with more force, the siren's wide hips colliding with Chrysalis' lap so hard that the purple fur started to bruise. The changeling was trying to break her, but Aria had other ideas.

The siren had noted that the changeling's large gonads were resting on the hammock, the bulging mass spread just under her, incredibly vulnerable. Smiling diabolically she raised her hooves over her head and waited. Unaware, the changeling pulled her down in a mighty plunge, and just as the black cock violently rammed her deepest wall Aria swung forward and used the momentum to hammer her hooves on Chrysalis's ballsack, nailing the precious twins with a rock-shattering smash. The resulting scream of pain was music to Aria's ears. The siren took so much pleasure in the changeling’s agony that she spontaneously came, her walls rippling, mare-squirts landing on the black nuts she had just cracked. Her cervix opened wide as her orgasm ripped her body apart, insuring she was about to be knocked up unless she completely destroyed the changeling’s testicles. Moaning sensually at the thought she raised her shaking hooves, preparing to deliver the coup de grace.

Before she could land the second blow Chrysalis magically yanked her ponytails backwards, making the siren arch back and stare at the ceiling. Chrysalis snarled as she violently resumed her pounding, trying to hold back from biting her neck and ripping it to shreds. Then Aria started laughing, taunting her, and the changeling decided that she was going to taste her blood. She opened her maw and lunged at her unprotected neck, but just before she could gore the siren something purple and blue collided with her nose.

Sensing the changeling’s attack Aria had reacted quickly, throwing herself back and delivering a powerful headbutt to Chrysalis’ snout. Dazed, the queen fell back on her back, her magic blinking out of existence. Aria, still shivering from her still incoming multiple orgasms, swiftly spun on the changeling’s dick like a top. The siren was now facing her foe, a blindingly bright red pendant shinning on her chest, fueled by Chrysalis’ pain and hatred. Straddling the changeling, Aria roared with victorious laughter, and then she started to sing.

This was not a melodious aria meant to charm the queen, nor a lullaby to put her under the siren’s spell with gentle persuasion; it was a harsh shanty promising pain and plunder, a horrible tune about rape and torture that would make the most hardened sailor blush. Aria wasn’t trying to bewitch the changeling; she was trying to break her mind into a million pieces, make her experience the pain she and her sisters had been subjected to in a concentrated dose. She was mindfucking the changeling into submission, growing stronger and stronger as the queen squirmed in pain. No sane mind could endure such a treatment.

But Chrysalis’s mind was far from sane. Roaring in rage the changeling broke free from the siren’s mental domination, her magic seizing the insolent little shit. Thankfully for Aria the pain had brought the changeling to a new high, any thoughts of killing the siren forgotten over the feeling of her vengeful balls starting to deliver the thickest load they had ever produced. Gritting her teeth Chrysalis didn’t stop to hilt and claim her unprotected womb, instead she squeezed the siren and jerked Aria on her dick faster than before. The sperm ran fervently up the changeling’s over-stimulated shaft and gushed messily as the pony still bounced up and down in a blur. Spunk exploded everywhere, squirting around Chrysalis’ convulsing shaft, the spurts punctuated by Aria cursing like a drunk sailor, her voice shaky as her continuous orgasms made her delirious.

“I HAD YOU, you fucking *spuurt* take your stupid cock *spuuuurt* with a fucking wrench *spuuuuuuurt* mounted by a pig! *spuuuuuuuuuurt* Ah shit, you got some in my mouth you fucking *spurt* I hate you!”

“Me too...”

Chrysalis sighed heavily as she shoved Aria down one last time, keeping her pressed against her lap as she unloaded directly into her welcoming womb. She did want to make sure the siren carried her brood after all. Her magic faltered, Aria landing heavily on her hard chitinous chest. They laid belly to belly in what could be misinterpreted as a loving embrace, both too exhausted from their respective orgasms to do anything. Down below Chrysalis' cock still spewed the white gelatin into the siren, her unforgiving balls working fervently; the monstrous length kicked robustly, making the siren's body jerk every time a new burst traveled up her cunt. Aria’s temperature rose, her nethers itching with need as she went into heat, but she didn’t care. That was the best sex she had ever experienced, the mindblowing orgasm still making her spine tingle. Her rough cunt quivered as streams of unbelievably thick spunk escaped around the spasming shaft; with her stomach pressed against the changeling her womb couldn’t grow very large.

After her balls finally relented, Chrysalis rose on her elbows, panting hard. The siren was gasping with shallow ragged breaths, translucent fairy wings fluttering on her back. The changeling stared at them, cocking a spunk covered eyebrow. Aria had managed to regain her full powers faster than she had thought possible, but there was a simple way to deal with that problem. She smiled and opened her jaws, locking-on the siren’s lust, and started to drain her power. Aria’s love for their brutal exchange was delicious; Chrysalis could even taste her own hatred on the pony’s aura. Before long the siren wings were no more, but the changeling didn’t drain all of Aria’s reclaimed power; leaving her with just enough to fight back was more interesting. Her strengthened magic levitated the siren into a sitting position, her black shaft still hilted and hard. The red pendant was still blinking away, promising fun times ahead. Chrysalis suddenly realized just how messy the siren was, splatters of cum radiating from her groin all the way to her caked mane. Looking at herself she saw that she too was positively covered in her own semen; they needed a bath, badly. That gave Chrysalis an idea: she carefully spun the siren back to her original position, back turned to her, then her wings started to buzz.

“Oy, what the fuck are you doing?” Aria mumbled as Chrysalis took flight, keeping the pony snugly hilted as they flew down the caverns.

“Multitasking.” Chrysalis smirked. She embraced her new broodmare with all four legs, keeping her secured against her cock. "You seemed to have difficulties walking, I'm only doing you a service." She chuckled as the siren squirmed in her grasp, stimulating her further. She felt that contrary to her previous belief, Aria was going to be a very interesting toy. Thinking about it Chrysalis decided that all three sirens would remain her mates after the hive was created, not just Sonata. She scrunched her face in concentration as she spurted another load deep into her mate. Coming while flying was not as easy as she had thought. “You could call this mid-air refueling.” She joked as her cock burst with a particularly potent spurt.

“Do you come harder when you are flapping your yap or something?” Aria snarked, her belly starting to grow. She actually didn’t hate the feeling.

“Apparently.” Chrysalis tilted her head. “Can you call me a bitch again?”

“You fucking degenerate rotten to the core queen of all bitches.” Aria recited eagerly.

“Wow.” Chrysalis’ cock seized, her flare reaching record seizes as her balls seemed hell bent on making the pony go pop. “And apparently I do it when someone’s insulting me too.” She winced as her sensitive flare was massaged by Aria’s walls, a moan escaping the siren's lips. “Are you enjoying this?” Chrysalis gave a powerful hump, losing control and crashing sideways. She quickly corrected her course, leaving a white impression of her flanks on the green wall.

“Fuck you.” Aria responded with a smile.

“Uuugh.” Another big spurt. Maybe she ought to be afraid of dehydration with the sirens around. Between her obsession with Sonata, Adagio's mighty rack and Aria's feisty spirit Chrysalis was in for an interesting breeding cycle. And the purple pony in her grasp had one last trick in her bag: the siren started to constrict on the fat cock inside her without mercy, her internal muscles much stronger than Adagio's.

"I'm going to do my best to ruin your fucking life you pathetic little shit.” Aria rumbled darkly, working her powerful hips into a veritable cock compressor. “I'll let you fuck me just because I enjoy your ugly little prick. You like it when I squeeze you?" Aria wiggled, trying to get more of Chrysalis' spewing cock in her, before tightening even more. "I don’t even need my siren powers, I'll bash your skull open in your sleep!"

Chrysalis's body was hunched over the pony, desperately trying to get more of herself into the tightest pussy she had ever penetrated, her balls now emptying in one long ejaculation that was fueled by the siren's words. The changeling's tongue lolled out of her mouth, the long organ brushing against Aria's snout. Chrysalis squealed in pain when the pony bit down on it with all her strength, her cock only getting harder, still compressed in its velvety prison. Her flared head had been squashed into submission, and when Chrysalis gave another powerful hump her cock-head unexpectedly rushed past the pony's stretched cervix.

"AH! You BITFT!" Aria growled around the meaty organ she was chewing on. She bit harder and harder as she was filled with stronger and stronger bursts of incredibly dense semen. Her belly was bigger than Adagio's now, but she didn't care. As far as she was concerned the first one to let up lost this battle. So she just kept on tugging at the wiggling tongue, contracting her nether canal, while the changeling kept thrusting into the painfully tight sheath . Chrysalis for her part was lost to the world, all her thoughts centering around the fact that her flare was currently freely mushrooming inside her mate's very womb. Such a penetration was hardly natural or advisable, possibly harmful to her future brood but she just couldn't get her flare out, too wide and much too hard to pass the cervical wall. The thought of mating like a dog, stuck to her bitch with a pseudo knot, only made her thrust harder, her flare bumping against the far wall of Aria's uterus then on her cervix as it continuously fired. She didn't know how her cock was going so far, and she didn't care. Trickles of lumpy seed escaped Aria's destroyed womb, the shaft ramming into it without pause.

The pony and changeling tandem flew a haphazard path down the cave towards the other two sirens, colliding with walls and leaving a trail of spunk behind them.

Rough Ride

“And I will accept you calling me ‘your love’.”

Sonata stopped in her tracks, the words making her head spin. Chrysalis still had a thing for her, even after she had discovered the siren’s plans? What should she do now! String the changeling along? Rebuff her? Tell her I’m not interested and please don’t rape me again? She was no mastermind manipulator, she wasn’t even a competent siren as it turned out; she just had no idea how to deal with this. The eternal air-head hadn’t been in a relationship for more than a thousand years! A relationship that lasted for less than a week! She didn’t know how to deal with unwanted attention. Her sisters had an impressive collection of past suitors and kinky adventures, Adagio and Aria being no stranger to romance or booty calls alike, but Sonata had always been too absent-minded to be interested in romance. Or anything sexual really. Oh she was no virgin, that boat had sailed in her youth back when there were other sirens around, but since then she couldn’t remember ever sharing anything more intimate than a hug with anyone; it’s not that she was devoid of urges, it’s just that she cared more about the finer things in life. Like puppies, rainbows, food… She could do food. She couldn’t do this.

“Eeeep!” Sonata was yanked from her reverie as her sister tugged on her leg.

“Come on.” Adagio whispered, her eyes gentle.

They both trotted down the path slowly, the green muck on the walls providing ample illumination. The sirens were lost in their own thoughts; Adagio planning ahead, calculating risks against gain and setting up contingencies while Sonata wondered what the changeling resin tasted like. Anything to avoid thinking about what had just happened to them, even if it was hard being covered in stinky spunk. After a few minutes of silent trekking, Adagio suddenly tripped on a jutting rock, her heavy burden making her collapse with a loud sloshy noise. Sonata was instantly at her side.

“You okay?” Sonata asked, then winced at the stupid question; of course she wasn’t okay.

“I’m fine.” Adagio grunted, trying to lift her encumbered weight. Soft blue hooves helped her up, and she accepted the help with a grateful smile. A smile that fell quickly as the siren looked at her sister’s face, tears silently running down Sonata’s cum stained cheeks.

“Adagio…” Sonata was on the verge of another break down, her lips trembling.

“Don’t start.” Adagio cut in abruptly. She pushed herself up and set off immediately at a brisk pace, leaving her sister behind. It seemed cruel, but one of them had to keep a level head, a task that had been hers amongst their little group for as long as she could remember. Before long she heard Sonata scrambling to catch up. Good, that meant her littlest sister was moving instead of letting her worries anchor her down. They would go to the pond, get cleaned and go back to make sure Aria was okay as fast as possi… “BLOODY HELL!”

The inflated siren fell once again, harder than before because of her hurried pace; her massive belly was squished under her violently. She heard Sonata cry out, but she was more concerned about the rumbling in her nethers. It seemed her womb had decided that enough was enough, and she grumbled darkly as she realized what was about to happen. With a painful sting her cervix popped open and released the flood gates, a veritable torrent of sperm gushing out of her, splashing against Sonata’s hooves. The diminutive siren almost slipped on the gooey tsunami as she rushed to her fallen sister. She stopped just behind Adagio, taking in the strangely hypnotic spectacle of the thick geyser rushing out of her sister’s insides, the smell of fresh spunk making her nostrils flare. She was horrified to find that the pungent odor didn’t repulse her; on the contrary she felt her little pussy quiver, begging for a taste. And boy, was she hungry.

“Brilliant…” Adagio snarked.

Her whole underside was now positively drenched as the splooge started to run down the slight incline, flowing around her. Her womb constricted one last time before sealing itself up. She turned on her side, appraising the slightly flabby look of her belly: her golden coat had been stretched to its limits but the fur was already smoothing itself back to normal. Ponies were just weird that way. She massaged her stomach with a hoof, making sure everything was in its place, and frowned at the bump she found. Her womb may have expelled gallons of seed, but there was still a lot left inside. She pressed harder and was satisfied as a splutter of spunk rushed into her cunt, pooling into it. She worked her pussy into pushing the load out, lumps of white muck dribbling from her lower lips. She tensed with fright when she heard something sniffing at her crotch. She braced herself, sure that Chrysalis was behind her, aiming to refill her. She turned slowly and froze: she was not ready to find her innocent little sister back there, face almost pressed against her sperm encrusted rump, breathing in the stench with a dazed slutty expression.

“Sonata?” Adagio whispered, careful not to startle the entranced pony. Sonata’s lidded eyes fluttered open, her dopey grin slowly meting into one of surprise, revulsion, then despair. “Hey, cut it out, now!” Adagio put as much authority in her command as she could, but to no avail. Sonata’s eyes welled with tears, silent sobs racking her body as she realized what she had almost done. “Hey… No…” Adagio tried in vain to shake her sister out of her spiraling thoughts, but it was too late, a wail escaped the distraught pony, tears running freely. Adagio sighed, sitting on her soaked haunches, and opened her forelegs wide. “Here, common.” She said gently.

Sonata launched herself into the offered hug, their bodies colliding with a wet slap. She bawled into her sister’s shoulder as Adagio ran a cum stained hoof over her head, petting her lovingly. Adagio would have been afraid of soiling Sonata’s pretty two toned blue mane, if not for the fact that the ponytail was already drenched in drying lumps of spunk. They were both absolutely covered in semen. Chrysalis’ heavy scent was everywhere. And it seemed to be driving Sonata crazy.

“Shhh, it’s okay.” Adagio cooed, nuzzling the side of her sister’s head. “That monster won’t touch you again, I promise you.” She lied softly.

“But I can't stop thinking about her!” Sonata whined needily.

"You want sex, not her."

“Why do I want that?”Sonata moaned, squeezing her sister tighter. “I’m a slut!”

“Sonata, how do you feel?” Adagio asked calmly.

“I’m hot, my kitty is all tingly and I can’t stop thinking about eating lots of changeling jelly!” Sonata cried, on the verge of hysteria.

“Sonata...” Adagio yanked on her sister ponytail with a sharp tug. She ignored her squeak of surprise. “Do you remember in what kind of body you are right now?”

“A… A pony?” Sonata sniffled. “A dirty pervy pony that wants to get wrecked by a huge black di…”

“A pony in heat.” Adagio interrupted, an edge of annoyance bleeding into her voice.

“Oh… Oooooh yeah.” Sonata’s tears dried, her face turning from distraught to pensive. “But what about you? Aren’t you in heat too?”

“Of course I am, didn’t you see how much that bug pumped into me?” Adagio’s voice returned to her haughty self, and she pushed her sister away. Not too roughly though. “Look at that!” She pointed to the stream of spunk traveling down the tunnel. “How in the world could she produce so much?!”

“But why aren’t you, you know,” Sonata twirled a hoof in the air, her face flushing as she looked at the delicious treat running across the ground. “horny?”

“I am aroused, oh believe me I am.” Adagio frowned, hating how her body was hankering for another dose of changeling cream. “But my self control is stronger; after centuries of paramours and lovers it ought to be. This isn’t my first rodeo.”

“Welp, that’s no help to me.” Sonata kicked her hoof dejectedly.

“Sonata,” Adagio sighed, reluctant to have this discussion with her innocent sister “when’s the last time you had sex?”

“Well just now! Didn’t you see Chryssi stuffing me like a turkey?” Sonata’s tongue ran over her lips, searching for a companion.

“I MEANT BEFORE THAT!” And that was why Adagio usually reserved ‘girl talk’ with Aria. It already was mortifying enough without having to repeat herself. She then frowned, whispering to herself, too low to be heard. “Chryssi?”

“Hmmm...” Sonata scratched her chin, thinking deeply. It took a while. “Do you remember Pizzicato?”

“Pizzicato? Pizzicato Shivers?” Adagio asked, really hoping she was hearing wrong. “That nerdy hippocampus that kept hitting on you back in school?”

“Yep. That’s him.” Sonata beamed, clopping her hooves together. Her nostrils flared, and she brought a leg to her snout, her eyes derping as she sniffed the spunk glazing her fur.

“You can’t be serious. That was more than fifteen centuries ago!” Adagio couldn’t believe this. She knew her sister wasn’t as outgoing as her and Aria, but this was just ridiculous. “And before that… Stop it!”

“Hmm?” Sonata’s eyes refocused and she stopped licking her coat clean. “Oh, there was no before. He was my first.”

“And your last.” Adagio deadpanned, incredulous. “No wonder you’re so worked up, centuries of pent up sexual frustration and now you are experiencing equine heat for the first time.”

“So what’s going to happen to me?” Sonata asked, her tail wagging to cool her burning nethers.

“Lets just say you are in for a rough ride.” Adagio exhaled and turned away, resuming their route to the pond and carefully avoiding the spunk carpet. “Maybe you should just let yourself go wild next time you… ‘meet’ Chrysalis.”

“But… But she’s evil!” Sonata cried, trotting after her sister, choosing to walk on the white sticky path.

“And we’re not?” Adagio looked back, frowning at her sister as Sonata jumped in the white puddles, splashing her hooves in cum with a happy face. She rolled her eyes. “Chrysalis is obviously after more than just your body, so I’m positive she won’t hurt you if you take the initiative. And you are wound up tighter than a guitar string, your heat will make you go crazy if you don't indulge a little. If you can make Chrysalis care about you even more it will solidify our bargaining strength. And it will make her more susceptible to our powers if she turns out to be an unsatisfactory ally.”

“So you’re saying that I should get on her good side?” Sonata was a little disapointed that the ground was dry again, the massive cum-spill exhausted.

“As long as that bug doesn’t hurt you again.” Adagio growled with malice. “If she does, we either get her under our spell or we kill her.”

“Sounds good to me!” Sonata said happily, her ears perking up as her voice came back with an echo.

The two sirens emerged in a vast chamber, the walls glowing with a bright green sheen, revealing a large basin of clear water nestled against the far side. The natural pool was fueled by a spring source in the ceiling, the changeling resin forming a tap to let the stream past, the water gushing into the pond in a gentle drizzle. Small cracks on the lake’s bottom let the water escape, giving the surface a placid and limpid aspect. The cave was riddled with tunnel entrances, some going up and some going down, all of them glowing softly. Before the sirens could take advantage of the beautiful scenery their ears swiveled backwards, hearing a strange commotion. The two sisters turned, gazing at the tunnel they just exited.

“What’s that?” Sonata piped up.

“I don’t know…” Adagio narrowed her eyes, her ears perked. “I think that stuff on the wall absorbs noise like studio insulation.”

“Kinda sounds like one of those old flipper machines.”

“That would be just silly… What the hell!”

The two sirens had to jump aside as a ball of black and purple cannoned into the chamber. The writhing mass collided with the ground and collapsed in a heap, revealing an unconscious changeling queen mounting a panting siren. Aria had Chrysalis’ tongue in her jaws, and was doing her best impression of a wolf trying to rip out a morsel of meat. Too bad her pony teeth were blunt and soft. When she realized that the queen had stopped moving the siren spit out the crumpled tentacle, laughing viciously.

“I WIN!” Aria shouted from under the changeling. “Take that you BITCH! Oy what the fuck, why are you still cumming?!”

“Aria!” Sonata ran to the downed duo while her sister followed slowly, a calculating expression on her muzzle. “Are you okay? Did she hurt you? Oh wow your belly is huuuge! Can I have some… I mean that’s awful!”

“Shut up and get her off of me.” Aria grunted, trying to buck the sleeping changeling away.

“Right!” Sonata nodded. She looked at Chrysalis' imposing mass. “How?”

“Do you want me to draw you a picture?” Aria shouted. “Start by making her roll-over you dolt.”

“On it!” Sonata put her forehooves on Chrysalis sides and pushed. The interlocked pair rolled easily, Aria’s round humongous belly easily supporting their combined weight.

“That’s better.” Aria breathed as she laid on her side, the pressure in her womb decreasing.

“I knew I felt something familiar.” Adagio approached, staring at the glinting pendant embedded in her sister’s fur. Sonata gasped as she saw it, her hoof rubbing her chest to check for her own jewel, but it was still hidden under her coat. “How did you do it?”

“Easy.” Aria smiled smugly. “I gave this bitch the ride of her life.” She sent an elbow into Chrysalis’ sides, the queen still unresponsive.

"And what else?" Adagio pressed impatiently. If she was to beat Chrysalis in a battle of wits she needed all the information she could get.

"Oh nothing much." Aria grinned wolfishly. "Just busted her balls with a sledgehammer blow. Her pain and anger were delicious."

"Just physically hurting her was enough?" Adagio schemed furiously.

"Sure was. I really should have transformed right then, but I was having too much fun, now it's too late." Aria frowned slightly. "I think she drained most of it somehow.”

“Did you try to use your singing?” Sonata inquired, grabbing the changeling's back legs, pulling Chrysalis from her sister's insides. She tried to avoid starring at Chrysalis' balls, but failed miserably. She also noted that they kinda looked battered, an angry red shine burning over the black skin.

“Yes, and it didn’t work.” Aria grumbled as the cock imbedded in her was dragged out.

“Two times our singing has failed now.” Adagio narrowed her eyes. “Maybe if we all sang together we could still have a chance to bewitch her, but I’m starting to think she's just too resili…”

“AOUCH!” Aria shouted, wincing. “Stop it Sonata, you’re pulling my insides out!”

“Eeep!” Sonata stopped pulling, dropping Chrysalis’ legs. Her last heave had dragged her sister along with the queen. It seemed that the changeling’s cock was stuck.

“Dumb bitch shoved her flare into my womb.” Aria growled.

She grunted as the black shaft jerked and fired a weak spurt into her overstuffed womb. Sonata started drooling as she stared at the jerking member, a trickle of smelly seed creeping around her sister’s entrance. The last spurt seemed to take a lot from the turgid member, and it suddenly started to flag. Aria smiled. If Chrysalis’ cock was failing, all she needed to do was make it cum some more and she would be free. She opened her mouth to insult the changeling but she was distracted when Sonata moved closer to her groin. She stared at her little sister with raised eyebrows.

“What’s up with dummy?” Aria nodded to her flustered sister.

“In heat.” Adagio said impassively.

“So? We're all in hea...”

“And hasn’t been laid in fifteen centuries.”

“Seriously?” Aria’s head jerked back, searching her older sister’s face to make sure she wasn’t joking. She grinned. “Hear that Queeny? You were the first to fuck my little sister since the last ice age!” She chuckled when Chrysalis’ cock weakly spurted, getting even smaller. Her flare was still too large though. She needed a little more. Her ears perked at Sonata’s desperate sniffs, and she got an idea. Aria got a wonderful, awful idea. “Hey Sonata!” her sister barely registered her call, answering with a small mumble. “I’m sure you are hungry, why don’t you have a taste?”

Aria grinned widely, ignoring Adagio’s scandalized expression. The older siren didn’t have time to protest before the youngest had pressed her muzzle into her sister’s groin, letting out a whine of excitement. Sonata began to lap the oozing pussy lips eagerly, her tongue bringing the pungent seed into her mouth just like a cat drinking milk. Adagio cringed with disgust, backpedaling away from her littlest sister eating Aria out, almost retching when she saw the satisfied look on Aria’s face. Adagio knew that her younger sister was into some kinky stuff, but she had never imagined that she would be interested in incest. Adagio thought about all the times she had agreed to share a shower or a bed with her little sis back in the human world. The requests had seemed innocent at the time, just sisterly bounding moments between Aria and her. But now Adagio wasn’t so sure about her sister, especially considering all the times Aria had 'accidentally' touched her, the siren's wandering hands often straying between her legs and over her breasts, groping and squeezing in her 'sleep'. She had never considered it an issue, since they were sisters, but now she regretted sleeping in the nude.

“Hey Queeny, you feel that?” Aria laughed, enjoying the spectacle of her little sister pressing her snout into her small teats while Sonata’s tongue cleaned her cunt. “That’s your darling Sonata licking your cum out of my pussy. Looks like she’s ready for another ride.”

Aria smiled widely as Chrysalis’ cock jerked powerfully, a surprisingly strong gush of cum erupting into her womb, before it was completely spent. The flare deflated as the length softened, and an instant later the sagging dick slithered out of Aria’s cunt, retreating into the safety of its sheath. A deluge of seed rushed from her womb, her cervix still destroyed. The spunk was incredibly thick, the goo clinging together like gelatin, and it splattered heavily into Sonata’s mouth. As soon as Aria’s pussy had been uncorked the lusty siren had pressed her lips against Aria’s pussy, trying to eat as much as she could. Adagio dry heaved at the sounds of slurping and sensual moaning. She thanked the stars as the gush tapered out, Aria’s belly returning to normal. Sonata lapped the dying stream urgently, and sighed as it stopped.

“Tasty.” Sonata said with a dreamy expression. Her chin was covered in lumps of seed, the thick strands swinging as she talked. She burped daintily and rubbed her stomach contently. It took a few seconds for her brain to catch up with reality, but when it did… “EEEEEEEEEWWWW!”

“Quite.” Adagio said from several paces away, green in the face.

“I always knew you were the most fucked-up of us all Sonata.” Aria chuckled, getting on her hooves. She managed to stand on shaking legs, before sitting down heavily on Chrysalis’ crumpled form. “So,” She said, as if nothing out of the ordinary had just happened. “what do we do with Queeny here?”

“Eeew eew eew eew eew!” Sonata was running around like a cat surrounded by vacuum cleaners.

“We could kill her, she seems vulnerable enough.” Adagio approached, still repulsed but willing to be pragmatic.

“Eeew eew EEEEEW…”

“Nah, she has her uses.” Aria brushed a hind hoof on Chrysalis’ sheath, watching it quiver.

“You perverted bitch.” Adagio said with a disgusted expression.

“Hey, we still have a world to conquer. Two worlds actually.” Aria shrugged, nonchalant about the whole thing. “And I don’t know about you, but I do like the idea of razing Canterlot High to the ground at the head of an army of changelings.”

“Changelings that we will have to bear.” Adagio groaned, repulsed by the idea.

“Maybe. Maybe not.” Aria whispered mysteriously, massaging Chrysalis' ample rump with a forehoof.

“In any cases we need a way to control the bug.” Adagio huffed. “Sonata has some influence over her…”

“EEEW, it's sticking to my throat!!”

“… but I don’t think we can count on her.”

“Relax sweet tits.” Aria laughed at the glare she received. “I got her figured out. You just have to flash your boobs and she’ll be putty in your hands… hooves whatever.”

“I can hear you...” Chrysalis grumbled, eyes still closed.

“Good.” Aria didn’t let it faze her. “Cause you have to carry me to the water.” She slapped Chrysalis’ ass, the shock making the surprisingly soft buns jiggle. “Mush mush Queeny.”

“As you wish, little bitch.” Chrysalis smiled, her horn lighting up. Aria flew into the air, surrounded by an emerald cloud she was very familiar with, and was promptly tossed across the cavern. “Look out; I think the water’s a little cold.” Chrysalis called just as Aria splashed into the pool, the pony screeching like a banshee.

Chrysalis chuckled then rose ponderously, shaking her head to fight the torpor. Her battered tongue retracted quickly, whipping her snout on the way up. She opened her eyes to find a cautious Adagio staring angrily at her.

“What is it little slut?” Chrysalis asked with a fanged smile. They both ignored Aria’s insults amongst the splashing. “Surprised to find out your sisters want my essence so much?” she purred. She started to circle the siren once again. “It’s not surprising, of course females want to bear my children, it’s only natural to search for the strongest male there is, to lust for his seed.” The queen dragged her snout on Adagio’s back as she reached her backside, letting her fangs drag across her coat, leaving a slight scratch mark. “I am only doing my best to answer your deepest desires, even if you don’t want to admit them.”

Chrysalis suddenly reared up and mounted the siren, whinnying softly as her tired cock slowly emerged, limply slapping Adagio’s rump. Before she could coax her exhausted member into action she was thrown off, landing on her side. She huffed heatedly, staring hungrily at Adagio’s haughty expression of contempt. Chrysalis then smiled wider; the siren had hesitated before bucking her aside, and before long she hoped Adagio would not even try to resist.

“Fine, I’ll fill you up another time.” Chrysalis snorted, getting to her hooves. “Sonata?” she called sultrily. The siren in question was rolling around on the ground, trying to forget what she had just done, but she looked up as her name was called. Her eyes widened and her nostrils flared as Chrysalis sauntered towards her, the changeling’s hips rolling sensually. She stopped just before her, her snout brushing hers. “Come with me, let’s get cleaned up my love.” The queen then turned, letting her recovering balls slap Sonata’s muzzle.

“Gaaaah…” Sonata followed obediently, her eyes locked on Chrysalis’ fat orbs and her limp swinging cock.

“Holy fuck this water is cold!” Aria had managed to reach the edge of the pool, her inept motor skills making the short wade through the shallows an adventure. Good thing ponies were buoyant. But now that she had stopped struggling she could appreciate just how chilly the spring water was. The residue of her ‘battle’ with Chrysalis was being drained away, the white clouds of spunk disappearing into the fissures at the bottom.

“Oh, is it really?” Chrysalis feigned surprise. “Let me heat it up, I don’t want my Sonata to catch a cold.” Her horn lit up, the walls in contact with the water first shining pink, then red. The pond began to steam softly, the crimson light reflecting all over the surface. It gave the cave a more sensual vibe, the warm glow making Sonata’s heart run wild. Chrysalis slowly waded into the improvised hot-spring, sighing contently as the water washed her exhaustion away; the walls of her new hive bled a little magic into the water, turning it into a potent regenerative bath. She ignored Aria’s death glare and laid down, letting the water cover her withers. “Are you coming?” Chrysalis asked huskily at a frozen Sonata. The siren rushed forward and put a hoof in the water; then she hesitated.

“Are you in my head?” she asked fearfully, not recognizing the emotions running through her mind, or the need burning in her body.

“No, I don’t need to.” Chrysalis smiled reassuringly. “Ask your big sister here.” The changeling smirked imperceptibly when Sonata cringed, the siren not daring to look at Aria. “What you are feeling is perfectly natural; your body is clamoring for a strong male, begging for release.” Chrysalis sniffed at the air, licking her lips. “I can smell your arousal, you must be hurting so much, you poor poor thing.” Sonata put a second hoof in the water, tense like a cat about to pounce. “I can help you make the burning go away.” Chrysalis murmured, watching her prey’s resistance crumble. She just needed a little push. “And don’t worry my love, I will be gentle.”

Sonata had heard everything she needed, and she launched herself into a mad scramble to reach the changeling. Chrysalis’ breath quickened as she gazed at her favorite mate splashing into the water, a desperate need etched on her blue muzzle. She used all her willpower to stop herself from jumping to meet her halfway, it was crucial that the siren came to her by her own will. Sonata panted with need and exertion, stumbling many times on the way, the warm water splashing against her burning pussy. She was finally about to reach her goal, and with a desperate whinny she cried out.

“MINE!”

Hearing Sonata repeat her own word, Chrysalis lost her tenuous grasp on her desires and lunged like a tiger, diving towards the approaching pony. Sonata didn’t even flinch; she just opened her mouth wide to accept the monstrous tongue that shot down her throat. She started sucking on the oozing tentacle as Chrysalis devoured her muzzle in her maw, her small hooves embracing her mate. The changeling and siren kissed desperately, the little pony carried by the queen’s forelegs, hooves groping her lithe flanks, all notion of self-control forgotten. They both explored their respective bodies with erotic urgency. Chrysalis didn’t even try to penetrate the slobbering pussy with her hardened mast, for this was not for her own gratification, this was about Sonata. She sat on her haunches and went to town.

“Wow, look at them go.” Aria whistled. She shot Adagio a quick look, the siren just now entering the water. “I guess Sonata wins, she’s got Queeny totally under her control.”

“Don’t kid yourself.” Adagio said somberly. She dodged a stray spray of changeling slobber with a disgusted wince. “Sonata is as much under her control as Chrysalis is under hers.” She sat in the water, amazed as her sore nethers began to heal; Chrysalis had only healed her insides after all.

“Aaah, lusty love.” Aria’s statement was punctuated by a loud moan, Sonata grinding her pussy on Chrysalis length, her thighs squeezing it tight. “It’s the best kind of love.” Aria ducked under the water as a burst of precum burst from the changeling’s thrashing cock, soaring over her head. She frowned as she emerged, and shouted at the writhing pair. “Oy! Look out for collateral damage, you pricks.”

“I’m surrounded by perverts.” Adagio sighed, making the mistake of closing her eyes just as the turgid length kicked again, this time in her direction.

“Well yeah,” Aria rubbed her groin to clean it of any residual stains as Adagio yelped. The water was taking away her soreness and fatigue. “And good thing too, if we are to deal with Queeny we better be ready to live a life full of cocks and facials.”

“Why are you so okay with this,” Adagio grumbled, splashing her muzzle. “I thought you would be the last to bend over and raise your tail so easily.” She dived, rinsing her poofy mane as well as she could.

“And you’re right.” Aria smiled dangerously. “But I’m gonna need your help.”

“Of course.” Adagio sighed, her limp mane dripping. “What do you need?”

Chrysalis could hear the two other sirens planning something, but she could not care less at the moment. She sat on her haunches, water splashing over her spread hind legs. She held Sotana steady, the siren’s forehooves pressed against her chest. Down below her dick was rubbing Sonata’s groin, the siren thrusting her hips frantically as her pussy coated her length with feminine arousal. The smell made her want to bury her cock into the siren’s small pussy and stake her claim for good. She wanted to hear her moans and her screams of pain mixed together, wanted to make her yell out her name as she would yell out hers. But first she would make the siren fall for her. Chrysalis ran her hooves all over Sonata’s body, she levitated globs of water to wash her fur, making the azure coat shine. She bathed every inch of her lovers body as her tongue played with her throat, Sonata sucking on the tentacle urgently. Their bodies were pressed together, Chrysalis’s mind slowly losing the battle with her breeding instincts. She wanted to put her cock into something, and she wanted it now.

Her wishes were granted when her cock-head sank into something warm and oh so soft, a generous squirt gushing out of the stimulated organ. Chrysalis stopped kissing the delirious pony in her grasp, and stared at Adagio. The siren's mane was limp, dripping with water, the long hairs clinging to her curvaceous body in a jaw-dropping display. The normally curled mess now sensually draped her flushed face, some strands stuck between her full bodied lips as she bit them with a lewd smile, the golden curtains falling all the way to her navel. Adagio pressed her gigantic teats together over her quivering cock, standing on her hind legs while her forehooves squished her udders together.

“Do be a dear and help me out.” Adagio said with a sultry gaze. “I can only stand on two hooves for so long.”

Chrysalis was so lost in a lust induced haze that she didn’t question Adagio’s sudden reversal. She surrounded the siren with magic and made her hover just at the right height, her flaring head nestled between her heavenly mounds. Adagio smiled and started to rub her jugs together faster and faster, refusing to stop even when Chrysalis precum started to spray her face continuously. The changeling moaned from the unbelievable teat-fuck, but she had not forgotten about her favorite mate. She turned Sonata belly downwards, the siren's forehooves on Chrysalis knees and her haunches in the changeling’s grasp. The changeling eyed her beloved’s honey pot for a single heartbeat, then dug in.

Sonata cried out in pleasure as the huge tongue was buried into her pussy, instantly making her orgasm. The tentacle didn’t stop until it hit her cervix, prying it open experimentally. The changeling was disappointed to find that the siren’s womb was still accessible, which meant she wasn’t yet fertilized, and her tongue started to thrash around like a snake in frustration. The smell of cock made Sonata come down from her high, and she realized that Chrysalis’ dick was just in front of her muzzle, pressed between her sister’s drenched teats. She didn’t hesitate one instant and started to suck on one of Adagio’s perky nipples, the taste of precum making her head spin. Adagio let a wince of revulsion escape her slutty facade, but Chrysalis didn't notice, too lost in the exploration of her mate's behind. The changeling’s fangs were threatening to pierce Sonata’s firm ass-cheeks as her tongue wiggled harder and harder, until the siren’s belly started to bulge visibly from the tentacle coiling in her cunt.

Adagio tried her best to maintain her charade as her baby sister nursed desperately on her udders. That had not been part of the plan, but she had to go with it. It made her teat-fuck slow down, but you didn’t see Chrysalis complain. She winced again as Sonata suckled more forcefully, her nipple disappearing into her sister’s mouth; the slurping sound was almost as loud as the wet sloshing noises coming from Sonata’s cunt. Finally Adagio saw movement behind the lounging queen, a purple hoof raised in an approximation of a ‘thumbs up’. She moaned, giving the signal, squishing her teats together more forcefully. The udder in Sonata’s mouth popped free, the siren opening her mouth and sticking out her tongue to let the teat slap her in the face repeatedly. Her look of utter contentment almost made Adagio falter, but thankfully Aria made her move.

The clumsy pony had taken a lot of time to skirt around the pool’s edge, avoiding Chrysalis’ gaze. She had felt a moment of panic when she couldn’t touch the bottom anymore, but as it turned out she was a better swimmer than a walker as a quadruped. She swam behind the preoccupied queen and dived, looking for a big rock. Finding one, she emerged silently and sharked closer. Once she was close enough she gave her signal, and as soon as she heard Adagio’s moan she lunged, grabbing Chrysalis’ wispy mane in one of her hooves. The Changeling gave a gargled scream as her head was yanked back, her tongue still deep inside Sonata. Aria swung her other hoof, holding the big stone tight, and bashed Chrysalis’ horn with a brutal impact. The green magic holding Adagio air-born instantly popped out of existence, the siren throwing her hooves around the rock hard mast. Chrysalis screamed in pain, her tongue slithering out of Sonata, and before the queen could do anything Aria yanked her confused and dazed sister from the changeling’s grasp.

“I’M GOING TO KILL YOU!” Chrysalis roared, holding her useless horn, sparks firing from its tip.

“Well, I better make my last moments count then.” Aria smirked, swimming to the shallows with her dumbfounded sister in tow. She was about to teach the changeling a much needed lesson: don’t underestimate sirens, or they will take everything you hold dear. Aria licked her lips, her hooves curling around Sonata’s body. Right now the little siren was Chrysalis’ most important treasure, and Aria was about to plunder it. Thoroughly.

Mile High Club

The placid surface of the subterranean lake rippled as Chrysalis tried to lunge at the retreating Aria, but the pain made her stumble, forehooves hitting the water heavily as her hind legs collapsed. The blow had rattled her horn to its base, sending vibrations all the way to her brain; her vision swam with double Arias pulling double Sonatas out of the water. Chrysalis tried to stand up and pursue her prey, but her head exploded with a symphony of pain, spots dancing before her eyes. She tried to clear her mind but another burst of sensations washed over her, making her head spin. Pleasure, this time, was radiating from her cock and making her dizzy. Chrysalis’ eyes focused on her groin, uncomprehending. She must have been seeing things, because there seemed to be a pony clinging to her length like a monkey.

Chrysalis tried to speak but her face contorted from sensory overload, all thoughts forgotten when the pony embracing her dick started to pleasure it. Adagio had begun to noisily slurp on the head of the giant cock, hugging it tight. The siren was adept at giving head, she knew the weak spots on the cocks of many species, and she transcribed her knowledge on Chrysalis’ member. She opened her mouth as wide as she could, managing to pop the blunt head inside. Her jaws were forced open painfully, but she soldiered on. The plan was still ongoing. She sucked on the giant cock like a massive lollipop, running her tongue all over the edge of the soft flare. Precum drizzled onto her tongue, and she winced as her pussy started to burn in need. The taste was awful, and she couldn’t help but try to swallow more. The more she gulped down, the more her cunt begged for a dick, her womb gaping open, thirsty for more spunk. In desperation she began grinding her dripping nethers on the pole she was hugging, her slit slobbering all over the turgid length. Her swollen teats were pressed against Chrysalis’ balls, the contact making them both squirm. The changeling was dazed from the agony and bliss, but a loud voice cut through her disorientation.

“You like that, don’t you sis.” Aria chuckled.

Chrysalis’s slit-eyed gaze zeroed in on the hated voice, one of her pupils a little slower and wider than the other. She inhaled sharply, then hissed with venomous hatred. Aria and Sonata were sitting on the edge of the pool, dripping and flushed. The two sisters contorted together, their forms interlocked in a sensual embrace. The bigger siren was hugging her sister from behind, Aria’s hind legs holding Sonata’s thighs wide open in a lewd wrestling move. Sonata’s fragile slit was fully exposed, dripping with her own arousal and Chrysalis’ slobber, but you could barely see under the purple hooves rubbing all over her groin. Aria smiled wickedly as her forehooves dug into her sister’s crotch, finally fulfilling one of her most depraved fantasies. She played with Sonata’s small teats, tenderly pinching her dark blue nipples, enjoying her sister’s little squeaks of confusion.

“A… Aria?” Sonata mumbled, her mind still fogged by pleasure.

“Shhh, just enjoy this.” Aria whispered, pressing her muzzle into her ear.

“What are you doing?” Sonata squirmed, but she was held too tightly. “No… NO!”

Chrysalis’ frayed mane bristled as her love tried to get free, her rage making her concussion more painful. She watched as Aria reached for her sister’s lower lips, making Sonata mewl in protest. She lightly brushed against Sonata’s dripping sex, humming a sweet little tune. Aria stroked her hoof in circles over her sister’s pussy, petting it with extreme gentleness. Before long Sonata was winking uncontrollably, squirting juices in the water, in the direction of the changeling slowly falling into insanity. Aria took advantage of her sister’s contraction to dig a little deeper, the edge of her hoof sinking into her fragile glistening slit. She carefully searched for Sonata’s clitoral hood, found the quivering little nub and grinded more vigorously to uncover her sister’s love button.

Sonata’s moans of conflicted pleasure pushed Chrysalis’ to instinctively appeal to her magic, wanting to pry her mate from her rival, since her limbs were still too numb. Magic concentrated at the base of her horn, but the sucker punch had severely cracked its surface, making spell casting unstable. Power surged into her brain like an electric shock, the backlash making her cry out in pain. Aria heard her, looking up from her perverted exploration. She found the changeling’s mismatched eyes staring, brimming with tears and hatred. She smirked and rubbed on Sonata’s clitoris furiously, making the little siren shriek in bliss. Aria's smile widened as her sister came under her forceful hooves, then she mouthed one terrible word.

Mine.

Chrysalis’ howl was the most feral cry of rage that Adagio had ever heard, but she still held on. She didn’t know what Aria was doing to get to the changeling, but boy was it working; she was happy Aria had insisted on taking their sister to safety. She yelped as Chrysalis managed to stand on four wobbling hooves, making the siren fall in the water. Thankfully the berserk changeling’s head was still swimming with pain, and her forelegs buckled under the strain, falling face first into the pond. Aria laughed mockingly as her rival stumbled, with her head down and ass up it looked like she was bowing to her. Adagio emerged and shook her long mane out of her eyes just as Chrysalis’ head sank under the water, and her heart rate skyrocketed: the water was regenerative, the blow to her head would be healed in a just a few instants. Without wasting time Adagio scrambled under the hunched changeling, positioning herself carefully. She had just lined up her cunt with Chrysalis’s cock when the infuriated changeling rose explosively, water spraying everywhere as her furor was revealed.

Aria felt a thrill of abject fear, afraid for her own life for the first time in a long, long time; she hugged Sonata like a teddy bear as the changeling’s true nature emerged. Chrysalis was not angry. She had completely and utterly lost her damn mind. The changeling’s mane was crackling with latent power, hairs rising around her head like a neon green halo. Her muzzle was drawn back in a feral snarl, her chops revealing her rows of sharp predator teeth, ready to sink into the siren that had been foolish enough to encroach on her territory. Her feline pupils had completely dilated; her eyes were now completely black, just like a shark. This was not the sophisticated villain who loved to scheme, divide & conquer from the shadows and took time to goad her enemies. This was a bloodthirsty demon hell-bent on destruction, a beast that would have ripped the wedding participants apart before destroying Canterlot three times over.

Chrysalis gave a thunderous roar, the savage howl promising pain and death. The ravenous monster lunged forward. Adagio couldn’t stop the sharp wail of pain that ripped out of her throat: the flared head had plunged into her without mercy. She was pretty sure she would have been ripped open if the healing water wasn’t keeping her whole. Chrysalis was anchored down as she hilted, falling on Adagio with a wild snarl. The raging changeling tried to push herself back, but her flared head was bathed in the warmth of a fertile womb, begging for her semen. Unable to combat her instincts in her feral state the changeling started humping urgently, releasing her packed sperm in a rush as she stared at Aria, her eyes promising gruesome murder. The siren felt the waves of hatred hit her, and she cheered internally as her pendant grew stronger and stronger. She just needed one last nudge.

“Oh, are you choosing Adagio over Sonata?” Aria wondered aloud. “That’s so saaaad.” She grasped Sonata’s head between her hooves, making the confused pony look at Chrysalis pounding relentlessly into their sister. “Look at that, in the end you couldn’t even be her fucktoy for long before you screwed-up, like always.” Sonata’s eyes brimmed with tears. “She prefers your big sister, like everyone does.” Chrysalis’ hate was fueled by the hurt on her love’s streaming eyes. “But don’t worry sweetie,” Aria looked at Chrysalis with a maniacal grimace, grinning ear to ear “you can be mine!” she dragged her tongue over Sonata’s tear soaked cheeks.

“NO!” Chrysalis shouted, finally regaining control over her body, her berserk state subsiding as her rage was drained away. She shoved Adagio away, the siren too shocked by Aria’s actions to hold on; this was not what she had signed up for, she would never agree to hurt Sonata like that. The siren went flying into the water, leaving a trail of spunk as she went. Chrysalis charged her rival, but she was stopped on her tracks when a bright burst of light blinded her, before a shockwave of magic made her stumble. Aria started cackling, her fur shinning red as her siren powers awakened fully. Sonata fell limply into the water, knocked-out by the magical surge.

Aria’s body exploded outwards, her limbs shifting and stretching. Her hind legs fused together in a long and powerful fish tail, as the rest of her expanding body was covered in armored scales. Her teeth grew serrated, razor sharp and huge, the unholy offspring of a piranha and a wolf. Her size grew tenfold, as did the radiant jewel imbedded in her chest, fins sprouting from her back as she grew longer and longer. And to Adagio’s great disgust Aria chose to alter her body in one last sickening way. Adagio decided there and then to slap her little sister after this was over, see if she could put some shame into that girl; one-upping Chrysalis in that particular way also hadn’t been in their plans. Aria roared in triumph, the great flying half-horse half-fish soared through the air, a hippocampus reborn.

Chrysalis had sprung into action as soon as the transformation had begun, but not to stop it. Instead she rushed to Sonata’s floating body, bit gently on her scruff and hastily carried the unconscious pony away from the dangerous magical outburst. She heard Aria’s savage cheers but she was too focused on Sonata’s gentle breathing. The changeling was depositing her precious charge on dry land when something incredibly heavy landed on her back. Chrysalis’ head whipped around, and the queen found herself nose to nose with a familiar and terrible face.

“Hiiiiii!” Aria said cheerfully, showing off her huge canines. Her maw was now much larger that the changeling’s, the siren could probably swallow the queen’s head whole. Her bulk was twice as wide as Chrysalis’ body and thrice as long, dwarfing the usually imposing queen. “Aren’t you a sweet little thing?” She brought her huge forehooves around Chrysalis’ neck, immobilizing her.

“Clever girl...” Chrysalis growled, recognizing she had been had. All her hatred had been drained to fuel Aria’s transformation. It had all been a show, and now she felt emotionally exhausted and empty of all her residual magic.

“You’re mine now, little Queeny.” Aria laughed, dragging the changeling into the air, away from the pool’s edge. She constricted her fish tail around Chrysalis’ shapely behind as she flew close to the ceiling. “And I’m about to rock your world.”

“You don’t scare me.” Chrysalis smirked, keeping calm. “You were wise to neutralize my magic, but I don’t need it to win in a fight with you. My carapace is hard as steel, my fangs sharp as spears, my wings powerful as a hurricane!” Chrysalis started to buzz her wings, intent on showing this little upstart what it meant to be a changeling queen, but her concentration was shattered when something wet and pointy made contact with her behind.

“I know one place where you carapace is very soooooft.” Aria hissed, her serpentine tongue teasing the changeling’s ear. She contorted her lower body, arching her tail to bring her loins closer to Chrysalis’ rear.

“What the hay!” Chrysalis yelped, surprised despite herself. The suspicious barb impacted between her buttcheeks, making them jiggle. It also left a strand of viscous fluid behind; poison? “Since when do sirens have stingers?!”

“Since absorbing changeling magic can make you get freaky with your transformations.” Aria chuckled. She made some last adjustments, her new addition pushing Chrysalis’ ballsack out of the way. She licked her lips as she found the changelings dripping cunt, and readied herself to thrust. “Also, that’s not a stinger. That’s my dick you fuckwit.”

“What?” Chrysalis eyes shot wide open, not believing what she had just heard. But the thing teasing her fat slit open could only be one thing.

“Thank you for flying Aria Air International, and welcome to the mile high club.”

“WHAT?!” Chrysalis had just enough time to shout before Aria’s huge tapered penis speared her insides.

“FUCK YEAH!” Aria roared in pleasure. She did a loop of celebration before choosing to fly on her back, Chrysalis’ wings tickling her belly as the queen was pressed against her. She held on with her strong forelegs then started to roughly hump into the screeching changeling. Aria’s cock was enormous, its girth on par with Chrysalis’ flare, maybe even bigger. But the head was narrow and flexible, making penetration much easier; the rest of her widening length could just slide-in to stretch the changeling’s insides gradually. “Hey Queeny, can you get preggers right now?” The changeling went silent, and the siren saw Chrysalis’ eyes widden fearfully. “I’ll take that as a yes...” Aria squeezed her hooves tighter around her prey and gave an excited shove, making Chrysalis’ black cock swing like a pendulum, the length pointing up like a mast on their love boat.

If there was one thing Chrysalis avoided at all cost, it was being around males during her nuptial flights. It was the only time a changeling queen could be impregnated by non-changelings, giving them a larger choice of partners since they were able to breed with males and females alike. But Chrysalis was disgusted by the idea of being knocked up in such a way; she only saw her womb as a nurturing ground for changeling eggs, not hybrid foals. To be carried by the queen was a mark of superior stock in her hive: she selected the best drones to be her lovers, and only the ones she deemed worthy could fill her with their eggs. She had always seen her royal slit as a sacred ground. She idly remembered the last drone she had taken to her bed, D20-2001, such a sweetie, strong and passionate, a prime example amongst changeling drones. And now she had a filthy siren inside her, pounding away like a mad dog. She yelled and tried to free herself, but the over-charged pendant on Aria’s chest gave her the edge she needed. The siren smirked and opened her fang filled mouth wide.

Aria began to sing, her siren powers flowing from the pendant, twisting her vocal cords. Her contralto purr turned into a baritone rumble, a new voice emerging from the siren’s muzzle. It was a voice like warm cocoa on a cold winter night, a voice that could melt the most frigid and bitter female into a dripping hot mess, a voice that could transform the most inept male into a goddam sexual tyrannosaurus. A wave of erotic energy spread across Equestria as the world was graced with this song for the first time, and all over the world mares spontaneously went into heat without any reasonable explanation. It was deep, it was sensual, it was sexy, it was Barry White.

“Stop that noise!” Chrysalis squirmed madly but she was quickly overwhelmed by the powerful song. “We are not making love! And what is not enough?!” Normally she could have shrugged off the siren compulsion, but with Aria ramming her fat cock into her sensitive walls the words assaulted her mind, shattering her concentration. “Don’t call me your darling you miserable wretch!”

Aria continued singing merrily, pounding the queen with gusto. She timed her thrusts to the beat of the song, using Chrysalis’ rump as a percussion instrument; she rammed the changeling about twice every second, the obscene sloshing from hitting Chrysalis’ balls marking the tempo. She compensated her relatively slow pace by putting all her strength behind each humps, making the changeling jump into her constricting hooves. Maybe she had made a miscalculation when she had given herself a dick, because the changeling felt much too tight. Her cock struggled to get deeper, most of her shaft sliding under Chrysalis’ heavy balls, she only had sunk a small portion of her length; but that just made her thrust harder.

“I don’t care how you should feel, release me!” Chrysalis screeched, wincing as her cunt was stretched more and more by the unrelenting siren. Her eyes widened fearfully as the siren approached the chorus, Aria’s voice growing in proportion to the strength of her pounding. “No, don’t scream my name!” She barked. “Sonata’s the only one I…”

Aria exploded into the refrain with renewed vigor, and her girth finally overcame Chrysalis’ tightness. The changeling screamed bloody murder as the siren’s massive cock rushed into her, to Aria’s great satisfaction. The tapered end crashed into Chrysalis’ cervix, instantly prying it open. The narrow head wiggled into the changeling’s womb before retracting, only to come back and pry her open a little more. Aria increased the strength of her thrusts to avoid losing the tempo.

Feeling her last sanctuary invaded Chrysalis’ saw red; she would not let herself be taken so easily. So suddenly that it was almost impossible to see, she struck like a cobra, twisting her neck to get at the siren. She was surprised to find that her fish scales were more than a match for her, hard like dragon hide. If she had good leverage she could probably pierce Aria’s armored skin, but from her position it was just impossible. And to make matters worse she was starting to enjoy the pounding she was receiving, her womb responding positively to the siren’s intrusion.

With a shiver of dread Chrysalis realized that the siren’s song was starting to seep into her mind, the promises of love-making sending her heart aflutter. She was truly falling under the siren’s spell. She wiggled around in a panic and her horn unexpectedly ignited, finally recovering from the siren’s cowardly blow. Magic rushed into her veins, and with a triumphant smile she pointed her horn towards Aria’s muzzle, grinning at the surprise she found there. She charged a deadly beam of magic, took careful aim for the siren’s panicked face… and let the magic fizzle out, a moan escaping her throat. The song had her completely.

Everything was love, everything was pleasure, she could only think about that deep beautiful voice and the cock ravaging her insides. She couldn’t go against the melody’s compulsion, the siren’s powers ordering her to enjoy the rough fucking and think of nothing else than her own gratification. Just before she could fall into total oblivion she made one last ditch effort: instead of fighting the song she embraced it, and decided to ride it to the bitter end. She ignited her horn once again and focused on the siren’s feelings.

Aria was too busy enjoying the changeling’s cramped oozing insides to realize that her song was being corrupted right away. When she did it was too late: Chrysalis was not just a victim of her powers, she was now part of the song. The changeling used her returned magic to feed on Aria’s lust and bliss, while the siren absorbed Chrysalis’ hatred and pain. The feedback loop turned into Chrysalis’ favor, the queen giving the melody a new goal. Aria experienced a moment of panic when the changeling took complete control, but she quickly realized that Chrysalis wasn’t trying to go against the song. The changeling had taken the reins by embracing its message completely: make love. And she was going to obey; with a vengeance.

Adagio had Sonata in a loving hug, trying to console her littlest sister as the blue pony stared at the unfolding events looking anxious, ringing her hooves together. It was distressing to see how much Sonata cared about that damn changeling now. They watched with conflicted expressions as Aria and Chrysalis flew high in the air, and they didn’t see the green mist pooling around their hooves, taking hold of them. They were suddenly dragged, screaming and kicking, into the air. The changeling magic brought them into Chrysalis’ view. The queen was sweating and wincing, but she had a nasty smile on her muzzle all the same. Aria was watching the unfolding events curiously, and she too started to smile as she understood what the changeling had in mind. She went on with the song, attacking the last part with savage intent, her cock wiggling into Chrysalis’ womb with more and more ease.

Sonata squealed as she was dropped unto Chrysalis’ lap, the quivering black cock between her legs. She could feel the changeling’s desperate balls rubbing against her pussy, and she exchanged a look with Chrysalis. The queen was looking at her with pleading eyes, but she was leaving it up to her. Sonata was free to choose what she wanted. The changeling’s loving eyes were obstructed from view as Adagio floated in, the oldest siren flailing to escape. Chrysalis had no qualms about forcing this particular siren, and her black hooves took hold of her thighs, bringing the pony towards her unhinged jaws. Adagio tried to protest but the changeling’s tentacle slithered all over her leaking cunt, the remains of Chrysalis’ last ejaculation dripping into her maw. Sonata watched with horny interest as the tongue she was so familiar with ravaged her sister, Adagio going cross eyed from the pleasure. The little siren was presented with a choice: she could do nothing, she could use her mouth to pleasure the black shaft in front of her, or she could ride this beautiful dark beast. Her decision was easy.

As the song gained in intensity the four participants writhed with pleasure to the beat. Aria was delirious with unfamiliar bliss, her cock now hilting inside the changeling with each mighty thrust. Not wanting to finish too fast she extended the song, starting from the first chorus many times over, avoiding the last verse. She was cheating a little, but her long cock had struggled to penetrate fully, so she wanted to completely destroy the changeling’s insides before giving the queen her own gift. She kept ramming her cock with a savage rhythm, feeling her release rumble inside her body. An unfamiliar instinct took hold of her mind, clamoring she had to mark the changeling’s insides, claim the dangerous mare as her mate, and fill her with her spawn. Chrysalis could have her sisters, as long as Aria owned her body.

Chrysalis was moaning with the unprecedented feeling of a cock penetrating her womb, she had only allowed eggs in there until now. She knew what the burning in her belly meant; her body was changing to prepare for her inevitable pregnancy. Frustrated by her inability to escape the song she focused on twisting her tongue over Adagio’s dripping cunt. Chrysalis took her time to slobber all over her slit, pushing her lips apart before diving in. She searched for the siren’s hidden pearl, her fat tentacle teasing Adagio’s clitoris until the siren gushed explosively into her mouth. Satisfied for now, Chrysalis sent her tongue further, idly checking the siren’s womb. The changeling was surprised to find that her tongue could not penetrate Adagio’s cervix: it was magically sealed after her last filling, which meant that some of her eggs had been fertilized and had found a nesting site, a litter of changeling foals already beginning to grow inside her nurturing womb. Chrysalis’ heart soared despite her current predicament: Adagio was the first of her conquests to accept her seed. But the proud siren still hadn’t accepted her as a mate. It made Chrysalis more desperate to mount her and bring the stubborn mare into her herd.

Adagio was openly moaning in pleasure: the expert tongue slathering her insides was hitting all the right spots. Her womb was surprisingly spared from the changeling’s exploration, and she was thankful; her deepest chamber felt incredibly good as it was. She hummed as the tentacle coiled around her love button, pulling on her nub until she hit a powerful orgasm. And Chrysalis still wasn’t done, gobbling all her juices with apparent delight. Adagio decided that she could live with being serviced by the changeling in such a way, her mind going blank as she came once again, Chrysalis pressing her jaws around her groin to swallow everything she squirted. She leaned on her littlest sister’s shoulders to avoid falling on her face.

Sonata was riding the cock of her dreams with a dazed expression, the fact that she was in control made it much easier to take pleasure in the painful stretch she was receiving. She could even take it out before being filled and avoid any more risks of pregnancy. So she rode her lover, her little pussy gobbling the giant shaft rhythmically. Her big sister was right in front of her, limp beautiful mane cascading behind her, sweating and panting, her eyes unfocused. Sonata’s gaze followed a drop of sweat rolling down her heaving chest, until it splashed on her fat teats. And that’s when she realized that the changeling she was riding was undergoing a transformation. She watched with fascination as Chrysalis’ belly started to soften, the dark chitin becoming see-through. She could actually see her sister’s cock demolishing the changeling’s transparent womb. She rubbed a hoof on the clear surface, marveling at the way the strong hard carapace had turned into a soft pliable material. She squeaked as Aria gave a mighty shove and her cock distended Chrysalis’ womb, actually bumping against her hoof. The changeling’s muffled cry of pain made Sonata wince, so she redoubled her efforts, trying to pleasure her lover and help her bear with her crazy sister.

All four creatures were lost in a torment of euphoria as the transformed siren finally relented and let the song hit its last verse. Adagio and Sonata were already subject to powerful orgasms, their pussies constricting around Chrysalis’ tongue and cock, the changeling both anticipating and dreading the end of the song. On one hoof she would be allowed to cum at last, on the other Aria would be too. And with the way her womb was being battered there was no way she would escape being knocked up. She thought desperately for a way to escape such a fate, whinnying softly into Adagio’s rump, there had to be a way… But the song gave its last note. It was too late.

As soon as she was free from the song’s influence Chrysalis tried to shove Aria out of her with her magic, but the siren was holding onto her too tight, her cock pressed too deep. They all crashed into the pool below, Adagio and Sonata holding on to each other for dear life. As soon as they hit the water Aria’s cock throbbed, the whole length kicking as a jet of watery seed was fired from her loins and impacted into Chrysalis’ womb with the force of a fire hydrant. Chrysalis screamed in rage as her loins accepted the siren’s seed, releasing eggs to be fertilized. Sonata was enraptured by the sight of her lover’s insides being filled so completely, her sister’s cock spasming endlessly before disappearing from view under the milky liquid. As captivated with her sister’s orgasm as she was, she had forgotten to dismount the changeling. Too late did she feel the flare stretching her farthest walls, her eyes widening as her womb was opened. She brought her hooves to her distended belly, feeling the flare’s clear outline. She didn’t know if she was scared or excited, her confusion making her eyes tear up. Before she could break down her big sister rushed to her aid, like she always did, in the only way she could at the moment. Adagio tenderly kissed her sister full on the lips, holding Sonata’s head with extreme care and love as Chrysalis’ tongue still slithered in her insides. Sonata was too lost in a lusty haze to care she was kissing her own sister, she just knew she was someone that deeply cared about her, and that as long as Adagio was there the siren would always be okay.

Chrysalis snarled as her own release rumbled in her balls, the orbs jumping on the siren’s quivering shaft below. She could feel the disgusting siren sperm swirling in her womb, and she was enraged by knowing she would be impregnated by suck a weak bodied spunk: it was too diluted, not heavy enough and clearly had no adhesive quality. But she was no fool. Her changeling constitution would do everything to use the measly release to fill her with a host of changeling foals. This would be the first time she would actually give birth, and not expel eggs ready to be hatched. It scared her out of her mind. But she would not be alone. Sonata was still impaled on her shaft, the siren had not tried to pull out as she flared, so she had made her choice. Sonata was truly hers, and that alone could make up for everything. The fact that Adagio had already begun to gestate was the cherry on top. Of course she would still destroy Aria’s smelly fish cunt later, her siren body not immune to her changeling spunk. Her vengeful thoughts were interrupted by the feeling of Sonata’s hooves caressing her flare through her coat, lovingly hugging her hilted cock. She didn’t care about anything else anymore besides filling the siren with her brood.

Sonata hiccupped in surprise as the first gush of seed hit her insides. She deepened her desperate kiss, her tongue bumping against Adagio’s reticent teeth. A powerful jerk from the embedded cock made her collapse against her sister, the two of them holding on to each other as Adagio finally decided to unclench her jaw, letting Sonata explore her mouth. She still guarded her own tongue though. She almost bit down as her sister’s hooves started playing with her teats, fondling them, massaging them. She didn’t have to endure it for long as Chrysalis hooves found Sonata’s, offering a gentle embrace that the little siren was happy to accept.

The changeling and pony held hooves like true lovers as Chrysalis unloaded all her syrupy love into Sonata. The queen’s lower body rose with jerky lurches, humping into her lover everytime she spurted or whenever Aria pounded inside her. The large siren’s eyes were dazed, instinctually trying to cum as deep as possible, making Chrysalis’ swelling belly turn white under her translucent carapace. Adagio’s head was jostled as Sonata bounced on her lover’s lap, the older siren barely conscious as her sister sucked on her tongue. Sonata was swaying her hips sensually in harmony with Chrysalis’ every motions, taking great care of staying hilted as deeply as possible, loving the feeling of her swelling womb. If she wasn’t knocked up from this they would just have to try again. Sonata and Chrysalis shared that thought, their hooves squeezing in unison, their hearts swelling with love and lust.

Crazy Turbulence

Moans and ragged breaths were the only sounds in the large chamber, the group of interlaced mares slowly losing their last forces. Everyone soon collapsed in a panting heap, exhausted and satisfied. Adagio was the first to extricate herself from the pile of bodies. She was feeling light-headed and happy, and not just from her multiple orgasms; something had happened inside her and it made her strangely fulfilled. She stumbled in the water, letting the pool’s regenerative powers rebuild her strength, her long mane gliding around her in a halo as she lazily swam belly up.

She almost dozed off but a wet *slurp* got her attention. Looking over she saw Sonata flying in the air in a flickering cloud of emerald, Chrysalis carefully dismounting the small pony from her still spurting shaft. An incredible amount of spunk dribbled from the siren’s gaping slit, falling on the changeling before oozing into the lake. Sonata was gently lowered into the water, where she floated on her back peacefully. Her muzzle was stretched into a contented grin, her eyes gazing at the ceiling blissfully. Her belly was just slightly distended, but not much; Chrysalis didn’t want to spend all her reserves just yet.

That just left Aria. The full on siren was still trapped under the changeling, her gasps for air louder than anyone else’s. The continuous unfamiliar orgasm had been too much for the recently turned hermaphrodite, and now she was paying the price. Passing out with a deep rattle, she unclenched her hooves and released the changeling resting on her belly. Finally free Chrysalis rose ponderously, her wings buzzing to extricate herself from the siren’s cock; the long shaft slid out from the changeling’s black slit, and Adagio noted that her sister had been somewhat imaginative with her new addition. Aria’s cock was much too large and the shape completely wrong. It looked more at home on a giant dolphin than a hippocamp. Chrysalis frowned when no gush of cum followed the fat length. Aria had pumped her spunk directly into her womb, Chrysalis’ cervix sealing the whole thing deep inside her. She idly rubbed her transparent swollen stomach, watching the cloudy spunk swirl inside. Her body had accepted to be bred, to her great displeasure.

“I really should kill you.” Chrysalis hissed, eyeing the downed giant siren. She looked under Aria’s softening shaft then smiled; she could still level the playing field with her rival. “But you owe me a couple of litters first.” The changeling flew jerkily to Aria’s groin, landing with a stumble over her cunt. The siren’s slit was very long and narrow, a hint of pink flashing between her purple scales; it was also the biggest snatch Chrysalis had ever seen. The changeling bent down, carefully sniffing Aria’s cunt, and she was happy to find that no, it did not smell like raw fish. It smelled like a mare in heat. She stepped over the siren’s vulnerable pussy, drunkenly positioning herself. Chrysalis’ cock was still spurting from her flared head, and she used a hoof to aim her spasming cock while her magic pried the tight slit open, the lips parting with great resistance. “I’m going to fill you with my foals you little bitch.” The changeling hissed, her thick splooge hitting Aria’s pussy, sliding inside.

Chrysalis was too tired to do anything but let herself fall, her spewing cock battering through Aria’s narrow slit and plunging inside. The changeling was surprised to find that the siren’s inside, while not very tight, were as muscular as her pony self, instinctually massaging her cock and pulling it deeper. Aria’s pussy rippled around her shaft with an incredible grip, coiling around her spurting flare; it was like receiving the most pleasurable blowjob from a mare with a thousand tongues, all slathering around her length. Chrysalis came harder, the stimulation making her hump, but she didn’t need to: the siren’s cunt convulsed, like a throat swallowing, dragging her black shaft deeper. Chrysalis’ eyes glazed over, and she just relaxed, lounging on the giant siren’s belly as her shaft was assaulted by Aria’s oozing walls. Her balls fired rope after rope of thick semen, the siren’s amazing cunt draining all her seed before bringing it to Aria’s thirsty womb, lodged deep in her body.

“Wow…” Aria mumbled; coming to. She winced as she felt Chrysalis gushing inside her. She stared at the exhausted changeling and raised an eyebrow. “I thought you didn’t like fish?”

“I don’t, it’s awful.” Chrysalis lied, her cock spurting more potent streams of spunk.

“Yeah, I can tell you hate it.” Aria smirked. She raised her body slowly, flying upright.

“I’m not finished here.” Chrysalis snarled, holding herself steady by hugging the siren’s huge body. She took Aria’s limp cock in her muzzle, threatening to bite it off.

“Aaah don’t be like that.” Aria grabbed the changeling, holding her in her hooves like a doll. She was careful not to extricate Chrysalis from her insides, not wanting to lose her brand new cock. The size difference was clearer than ever, Aria’s body was twice as large as her counterpart, and three times as long. “I don’t want us to fight, not when we have so many reasons to celebrate.” The siren gave a fang-filled nightmarish smile, but Chrysalis wasn’t impressed, holding a straight face as she continuously came. She did blush heavily as the siren traced circles around her now transparent and soft lower belly. “So many little Arias…” The siren groused, watching her cum swirl around the changeling’s sealed womb. Her cock started to grow inside the queen’s jaws, until the changeling gave a warning growl, biting a little harder.

“I’ goin’ to kil’ you swowly.” Chrysalis promised around her mouthful, almost sounding aroused by the idea.

“You can try.” Aria breathed huskily, she then dragged her draconic tongue on her personal broodmare’s black muzzle. Her cock grew longer and harder.

“Wift mah mawic at itft fulleft…” Chrysalis released Aria’s length, her breath hitching. The changeling’s tongue darted to twist around the siren’s in a strange tug-of-war. It lasted only a few instants, the changeling’s burly tentacle much too strong for Aria’s wiry ribbon. Chrysalis smiled with crazed eyes. “… you won’t stand a chance.”

“I know.” Aria muttered. The two of them stared hungrily at each other, Chrysalis’ cock spurting harder than ever. “I’ll just have to be smarter.”

“I hate you.” Chrysalis whispered eagerly, her length kicking in agreement.

“Me too.” Aria sighed, enjoying the thick cream filling her insides.

“Just kiss already.” Adagio deadpanned.

They both jumped at the interruption, Aria dropping the changeling. Chrysalis flailed as she fell backwards, her hooves sliding on the siren’s smooth scales, and her shaft gushed out her Aria’s slit; she splashed in the water with an undignified *yip*. As she emerged sputtering, Aria looked around. Adagio was keeping a respectable distance, watching them with a sour epression. Sonata drifted lazily nearby, lost in a peaceful slumber as she sailed across the pond, not a care in the world. Chrysalis sat on her haunches, the water up to her translucent belly, looking at her love with dreamy eyes. Her cock slowly retracted into its sheath, satisfied for now.

“Uh...” Aria followed Chrysalis’ eyes and gazed at the bump in Sonata’s belly. A strange instinct made her loins stir; it felt just like the rush of competition. She experienced a mad need to fuck the petite blue mare and fill her with her own cum, washing away the changeling’s sperm, taking her sister as her own. She cringed at the idea. “This is going to take some getting used to…”

“Touch her again and I will really kill you.” Chrysalis rounded up on the massive siren, totally serious this time. She noted with satisfaction that Aria’s pussy had gobbled all her semen up, only a few drops escaping the tight slit and falling into the water.

“Oh, so you were only going to pretend kill me before?” Aria chuckled. She flew through the air slowly, circling the changeling. “Don’t worry, I’m not going to do it with my own sister.”

“Could have fooled me.” Adagio called angrily, wading in closer with authority. She had her best ‘you are going to get spanked by your older sister’ face, ignoring that she was now tiny in comparison to Aria. “Did you have to make her cry?”

“Well since Sonata is a weak point for Queeny here,” Aria slapped the changeling’s head as she flew above her, making Chrysalis hiss. “it was the best way to get her angry. And it worked, didn’t it?”

“It was a nice plan,” Chrysalis admitted grudgingly “but if you try to hurt her again to get to me…”

“Yeah, yeah, you’ll kill me, rip out my dick yadi yada.” Aria waved a hoof dismissively. “All is fair in love and war, and this was about both.” Aria narrowed her eyes “But let’s get one thing straight: I love my little sis. I had to get you mad enough, so I did what I had to do; but only because you left me no choice.” Aria was a firm believer in tough love, but even she had her limits.

“So you aren’t just a huge pervert sexually attracted to your younger sister?” Adagio said accusingly.

“Oh, I never said that.” Aria smirked “I didn’t like hurting her feelings, but playing with that sexy little body of hers was almost worth it.” The huge siren licked her lips, chuckling when Adagio took a step back, looking outraged.

“Don’t even think about touching my mate like that again.” Chrysalis growled, her chops retracting to show her serrated teeth. “Learn your place, you lowly bitch.”

“A lowly bitch that just beat you at your own game.” Aria corrected, pointing to the changeling’s belly. “I’m thinking the see-through is not an esthetic choice, so I’m guessing I just got you knocked the fuck up.”

“And you’ll pay for it for the rest of your life.” Chrysalis grinned evilly, her eyes never leaving Aria as the huge siren flew around. “I’ll use you every day, again and again; I won’t stop even when you are round with my foals. I’ll let my children watch us when they are born, I’ll make them stuff you full of their eggs.”

“You can try, little Queeny.” Aria chuckled derisively. “But you’ll have to do better than last time.”

“You got me by surprise you coward!”

Adagio rolled her eyes and turned from the rising conflict. She waded to the side of the pool and clambered on dry land, shaking her fur. She began the arduous task of drying her long mane while her sister and the changeling bickered like foals.

“We’ll see what happens when the kids I stuffed in your cunt are born.” Aria pressed her muzzle into Chrysalis’ face, smiling. “Maybe my children will find your holes more to their taste.” Aria rubbed a gentle hoof on Chrysalis’ belly, looking her grumpy rival in the eyes. “Even if you win this little war of ours, I’ll always have the fact that you are going to carry my first spawn.”

“First? Truly?” Chrysalis’s head jerked back. She stared up at the siren with disbelieving eyes, forgetting her annoyance after the unexpected news. “You never had any offspring?”

“Nope.” Aria said, doing a careless backstroke through the air. “Same for my sisters.”

“Really...” Chrysalis rubbed her chin. She looked at Sonata, the siren doing her best impression of a paper boat, and she felt her heart race. She would father the beautiful siren’s first-borns; now that was very exciting. “I thought that you had seen your fair share, since you are so old. Especially considering how fast my seed quickened in the little slut’s womb.”

“WHAT?!” Adagio screamed at the top of her voice, making SS Sonata capsize with a squeak.

“I think she’s saying you’re preggers Adagio.” Aria informed helpfully.

“I HEARD!”

“What’s happening?” Sonata inquired, water spraying from her nose.

“Adagio is preggers.” Aria repeated.

“Already?!” Sonata shot her sister a surprise (and a little jealous) stare. “Congratulations?”

“NOT HELPING!”

“I should have known you would be the most fertile of your sisters.” Chrysalis grinned, sauntering to the fuming siren. “You were born to be a fine broodmare.”

“Don’t forget our deal.” Adagio snapped as the changeling rose from the water. Chrysalis approached slowly, rolling her hips sensually. “I’m not just your sexual toy…”

“But you are so tasty looking...” Chrysalis breathed sultrily. She rubbed her snout on Adagio’s cheek, sniffing her, ignoring the siren’s wince. “I wanted to mount you ever since I first saw you back in the forest; I can’t help but want to ravage you again every time I see you. And now that I know you are carrying my brood...” Chrysalis followed Adagio’s jaw line, peppering it with little kisses. “I don’t just want you…” the changeling’s cold snout traveled down the siren’s chest, kissed her shoulder, tickled her ribcage and dragged across her underside. “I need you.” Chrysalis finally reached Adagio’s flanks, and she hunched down to press her muzzle into the siren’s precious teats. Her face was pressed between the siren’s thigh and her belly, like a foal trying to nurse.

“You perverted bug.” Adagio breathed, trying to stay sill as her mounds were suckled one after the other, Chrysalis’ horn rubbing against her side as the changeling tried to swallow one of her fat udders urgently. “Have you no self control?”

“No.” Chrysalis mumbled, her mouth full. “Usually don’t have to hold back when I’m in heat.” She released Adagio’s teats and cantered to her rear, her cock showing its blunt heat as it emerged. She positioned herself behind the siren, her hooves kicking impatiently, almost rearing up a couple of times out of pure instinct.

“What are you doing?” Adagio shot the fidgeting changeling a dirty look, her flanks tensed to buck Chrysalis off as soon as she touched her back. “What are you waiting for?”

“You are the last.” Chrysalis panted, carnal need making her voice shake. “Sonata is mine, as I am hers.” The azure pony’s eyes widened at the assertion, her loins starting to burn once again. “The little bitch accepted her role; she will bear my foals as I will carry hers.” Aria smirked smugly, flying over the both of them. “You already carry my brood, but you still resist me!” Chrysalis snorted furiously, staring at Adagio’s tail, tucked between her legs and hiding herself. Her gaze travelled to her quivering flanks; she knew the siren would push her away again. Her wings buzzed and her jaws snapped in a territorial display.”What do I need to do for you to give yourself to me you little slut! Tell me!”

“Say my name.” Adagio sneered. “Say my name and tell me how much you need my body.”

“Adagio.” Chrysalis breathed, her cock beating against her barrel with violent *slaps*. “I need you Adagio, join my herd, I need to own you…”

“Pathetic.” Adagio’s word pushed the changeling into a frenzy. But the siren ignored the raging snorts and whinnies. “You call yourself a Queen? You are a slave to your own urges!” She whipped her tail away from her dry nethers, slapping Chrysalis’ snout. “I’ll allow you to use my breasts for your sick pleasure.” Adagio shook her hips, making her teats jiggle. She slapped the changeling one more time as Chrysalis rushed forward, making the crazed queen stop in her tracks. “But know this: if you continue, it will be because I allowed you to. You will take your pleasure because I was feeling kind. If you mount me, you will be confessing your weakness, you will be surrendering to me. You will be accepting my charity. Are you sure you want tha…”

Adagio didn’t have time to finish her taunt before Chrysalis jumped on her back, clambering on top of her with desperate whines. She laughed haughtily as the changeling’ cock rammed between her fat udders, her fur receiving a healthy coating of viscous changeling lubricant. The siren swayed her hips in opposite to the changeling’s thrusts, making the black cock miss her jugs. Chrysalis whinnied in desperation, trying to hold the siren steady, but failing. The changeling snapped her jaws around Adagio’s flowing mane but before she could pull Chrysalis grunted, opening her mouth. The siren’s firm backside had collided with Chrysalis’ softened belly, making her stumble back. When she reared up again her cock almost sank into Adagio’s slit, but the siren danced away, making the length slide under her once more. And the torture continued.

Sonata had been horny before, but when Chrysalis had mounted her sister her mind had thrown itself to her lust’s mercy. Her cunt was burning, dripping with slimy secretions that fell on the floor in abundant strands. She wagged her tail needily, the hair-strands brushing against her pussy lips. The thrashing tail spread her scent everywhere, the arousal of a mare in heat heavy in the air. And Aria inadvertently caught a strong whiff of it. The huge siren’s eyes widened, her cock rushing out of its pocket. Aria’s instincts shouted that there was a female nearby that was ready to accept her seed, and it was her duty to answer the call and breed her. Without thought she lunged at the source of the heavenly perfume, her mind blinded by the need to spread her spawn.

When Aria regained her senses she found herself nose to nose with a dazed Sonata. Her little sister was lying on her back, immobilized by Aria’s bulk, the pony moaning in need. Aria suddenly realized that she was thrusting into something incredibly tight, and she froze as she understood what had happened. Not used to her new reproductive urges, she had thrown herself at her own sister, pinning her to the ground as her cock tried to find her little pussy. And she had just succeeded, the tapered end narrow enough to penetrate her tight cunt. But the rest of her cock would undoubtedly tear her apart. Sonata whined loudly as her burning pussy was teased, desperate for more. Under the haze of her lust she didn’t recognize who was holding her down, but she dreamed about her changeling. Her beautiful, sexy and caring Chrysalis had seen her in need, and had come to satisfy her with her beloved huge black cock. So she moaned, begging to be filled.

Aria tried to shut out her sister’s calls, shaking her head to clear her mind. She loved her little sister, despite the way she acted towards Sonata she loved her innocent and bubbly nature. And she had to admit that she always had dirty thoughts about her and Adagio. But this was not what she had fantasized about. She had dreamed of heavy petting, kisses, rubbing, tongue play… The way she had explored Sonata’s body when she had taunted Chrysalis had been everything she had ever envisioned between her and her sisters. She wanted to have them sensually, make them squirm against her, hear them moan her name; she didn’t want to fuck them like a dog in heat. She ordered her body to move away from her little sister, the pony ridiculously minuscule next to her great bulk, but she didn’t budge. Instead she found herself thrusting urgently in shallow humps, the wider parts of her cock approaching Sonata’s tiny slit dangerously.

Sonata started to moan louder, and Aria had no other choice but to put a hoof on her sister’s muzzle, keeping her quiet lest Chrysalis saw them, the changeling thankfully too focused on Adagio at the moment. The giant siren tried to stop her thrusts with all her might, but her cock was unrelenting, stretching Sonata’s slit more and more as it sank deeper and deeper, her girth wider and wider. Her tapered head was desperately trying to reach her sister’s womb, she could feel its warmth teasing her pointed end, promising a fertile land to sow her seed. Aria winced when a careless lunge went too far, making Sonata’s eye bulge as her tight pussy lips were spread too wide. Her sister’s muffled cry of pain snapped Aria out of her stupor. Her great body jerked back, leaving Sonata spread eagle on the ground, the little pony panting. Aria shook her head once more, but Sonata’s scent was still strong in her mind, instinct overpowering her thoughts gradually. She needed to fuck someone. She needed to stuff her cock into a warm pussy. She needed her broodmare.

Chrysalis was fighting desperately against Adagio’s delicious torture, when a shadow fell over the both of them. The changeling had no time to prepare herself as Aria rammed her cock into her black slit, making her scream gutturally. Adagio grunted as some of her sister’s great weight pressed upon her back, stopping her swaying. Chrysalis took the occasion to enjoy her fat teats, thrusting between them while Aria tried to push all of her length into the changeling. But with the queen’s womb sealed, Aria’s cock could not go deep enough to hilt, and the length started to bend under the great siren's powerful humps, coiling inside Chrysalis’ cunt. Adagio cursed her sister’s interference, but she went positively white as she saw Sonata come over, a look of desperate need on her muzzle. Before the older siren could protest her little sister’s lips were on hers, followed by a wiggling tongue darting into her mouth.

Stuck between a thrusting changeling being ridden by a crazy siren and a pony eating her face out, Adagio threw her metaphorical arms in the air and waited for the crazy lusty storm to be over. She let her tongue be licked by her moaning sister, even allowing herself to kiss Sonata back gently, giving her sister all the love she could. Seeing her two sisters making out was too much for Aria, and her next orgasmic hump threw Chrysalis into Adagio, making the older siren yelp as she stumbled forward. Cum rushing into her cunt, the changeling held on to Adagio’s flanks desperately, grinding her length with high pitched whines as her flare grew, spurting precum everywhere. Sonata yipped as her sister was shoved into her, and she fell on her belly. She was about to stand up and resume her incestuous kiss when a pungent odor hit her nostrils. Chrysalis’ cock was covering Adagio’s belly with gooey bursts of precum, and Sonata couldn’t resist. She crawled under her sister, not registering her protests, and started to lick everything she could get her tongue onto: Adagio’s fur, her teats, and of course Chrysalis’ wonderful leaking member. Sonata didn’t know what she really loved more; the changeling or her cock. She soon decided that it didn’t matter, and started to make out with her lovers flare.

Feeling someone servicing her cock down below, Chrysalis started to hump frenetically, like the animal in heat she was. The frantic wiggling dislodged Aria’s spewing length, and her next thrust missed the changeling’s pussy. The long cock plunged against Chrysalis’ ballsack, finding itself sandwiched between the huge heavy testes, continuously spouting its watery seed. On her next hump Aria’s eyes rolled back, her tapered head sliding under the changeling and finding a pair of huge teats to slap against. Playing with Adagio’s breasts was one of Aria’s deepest fantasies, so having her cock slide between her udders turned into her number one priority.

Sonata was blindsided as her sister’s cock appeared alongside Chrysalis’ length, and she didn’t have time to blink before she was showered in siren spunk. She inhaled drunkenly as her sister’s semen splashed against her muzzle, the thin spunk running down her chest. The scent was much less pungent than Chrysalis’ semen, but it had its own charm, smelling spicier; Sonata couldn’t help but open her mouth, bring her muzzle close to the spurting tap and swallow just a few mouthfuls. Aria’s cock clashed with Chrysalis’ length, almost as if they were fighting for the right to nestle into Adagio’s bosom. Wanting to preserve the peace Sonata grabbed a cock in each of her forehooves, and started to pump. The effect was instantaneous as Aria’s length spurted her watery seed more urgently, a great deal of it slurped down Sonata’s throat, and Chrysalis’ flare mushroomed out of control. Sonata could actually see her lover’s balls constrict and jump to her body, so she knew what came next.

Not ashamed about her preference she completely abandoned her sister’s cock, the gushing length springing up to nestle between Adagio’s sopping teats. Sonata held Chrysalis’ cock with both her hooves, making the length bend towards her face. She licked the flared head with desperate need, flicking her tongue on Chrysalis’ quivering cock hole, lapping the last few drops of precum. Her hooves felt the surge run through the underside of the black cock, the huge release rushing to meet her face. Sonata squeed in happiness and opened her mouth wide, just as the powerful jet of heavy spunk gushed out. It was so thick and smelly, so much better than Aria’s, and it made Sonata’s head spin. The gooey flow impacted against her throat, filling her mouth instantly. She tried to swallow as much as she could, but before long most of the spunk was running down her chin, pooling between her thighs. As her pussy was bathed in spunk Sonata realized how hot and bothered she was feeling down there, and she had the perfect tool in hoof to water her flower.

Adagio was cringing in distaste since her littlest sister had disappeared under her, the slurping noises giving her a good idea of what was going on down there. She could feel Chrysalis’ length grinding between her teats before it started to hump harder, impacting with her belly painfully. She was about to complain when she felt something else slide between her udders. It was long, smooth, had a tapered head… Adagio screamed her disgust as her sister’s cock joined Chrysalis’, the length shooting its light seed all over her underside. Everything below was promptly covered, her fur turning white. She was about to try and escape the horrible warm shower when Sonata’s head reappeared between her front hooves, the pony squirming strangely. Adagio’s eyes widened when she felt her little sister grind her rump against her belly, and she understood: Sonata was pressing the changeling’s spurting cock against her pussy, like Chrysalis had done before. The siren stood frozen as she felt her darling little sister rub her butt on her belly, like she was asking Adagio to somehow mount her. The fact that it aroused her made it so much worse.

Sonata was squealing with happiness as Chrysalis filled her little pussy up. Getting the flared head aligned with her slit had taken some time, getting her back and mane covered in thick strands of spunk, but in the end it was worth it. The spurts of thick cum that made it in were clinging to her velvety walls, slowly trickling deeper inside, her cervix happily slurping it all up. She had a strange feeling, an instinct that told her that this was the one; this was the moment she would be inseminated by her lover. And chrysalis shared that intuition. Unable to stop herself the changeling tried to penetrate the much too tight opening, and her flared cock sprang up, sliding between Sonata’s buttocks. The careless hump pushed Adagio forward, the pony doing her best not to fall to avoiding flattening her sister.

Aria continued her careless thrusts, following the group as it shifted, her cock changing angle as Chrysalis’ balls pressed her length down. Aria moaned in pleasure as her length sunk into a tight opening, her tapered head prying open the little slit. She was too lost in her orgasm to care about who she was screwing; all she wanted was to hilt and spread her seed. So she thrust excessively hard, her tail pushing Chrysalis’ legs apart, her massive cock spurting as it tore the little opening apart.

Sonata’s shriek of pleasure startled everyone. Adagio’s pressed her ears against her skull. Chrysalis snorted excitedly as she tried to find her lover’s behind to answer her call. And Aria suddenly realized what she had just done. She stopped thrusting, but her cock was still firing, spurting a gush of thin spunk in a long drawn out ejaculation. She was filling her sister up with her seed, her pointed head lodged deep inside Sonata’s womb, as her massive girth destroyed her dainty little tunnel. The loud moan that followed from below only made her squirt harder. She could feel her semen swirling around Sonata’s baby maker, washing the thick changeling seed away.

Aria’s animal instincts roared in approval as she conquered her rival’s mate, marking her with her own scent. But her mind rebelled against that idea, her sisterly love clashing against her lust. After a few instants that felt like an eternity of bliss, she regained her senses and laboriously extracted herself from her little sister, spewing more than ever, her length slipped away just as Chrysalis realigned with Sonata’s raised rump.

Aria flew off the changeling’s back, Chrysalis too preoccupied with pleasing her mate to notice, the siren’s length retracting into its pocket from shock. Aria’s gaze was drawn to her sister, the pony's face pressed into the ground, her grinning muzzle swimming in a veritable ocean of mixed spunk. Her ass was raised in a very provocative way, tail tucked away, revealing her little pussy, completely wrecked. It seemed that in her haste to hilt she had positively obliterated Sonata’s cunt, her tight slit now gaping obscenely. Her cock was perfect to pry open and stretch any opening safely, so she hadn’t actually torn her sister’s flesh; but she wasn’t sure if Sonata would ever be tight again after this. Aria couldn’t help but feel a burst of primal satisfaction as she saw her sister’s distended belly. She had not pumped as much as Chrysalis could, but she still had filled her rivals’ prized mate with her own seed; there was no better feeling. And she felt sick for feeling so proud.

Her musings were interrupted when Chrysalis finally aligned her cock and tried to ground herself on Sonata’s tight slit. The changeling didn’t expect her flared head to plunge into her mate so effortlessly. Taking the occasion in stride Chrysalis’ horn ignited, levitating a battered Adagio from the pony sandwich, before properly mounting her unresponsive mate and thrusting away. Adagio grumbled darkly and approached her transformed little sister. She vowed to make the changeling pay one way or another, and she fretted about the new lives growing in her womb. Coming closer she realized that her sister was frozen in shock, eyes staring fixedly. Curious, she followed her sister’s gaze.

At first Adagio thought that Aria was being a pervert and was checking out her sister’s muff being ravaged, but her eyes soon widened. Every time Chrysalis hilted and filled Sonata’s womb, a spray of thin white spunk sprayed around the queen’s shaft, the watery liquid easily recognizable amongst the changeling’s thick jelly. That wasn’t changeling semen; it reminded her of the thin spunk that had bathed her underside, spurting from Aria’s brand new cock. She rounded up on her sister with a sickened expression. The guilty look on Aria muzzle was all the confirmation she needed.

“You sick pervert!” she hissed. Adagio slapped her little sister’s muzzle, having to rear up to reach her. Her hoof throbbed painfully, the siren scales hard as rock, but it was the gesture that counted.

“I didn’t mean to!” Aria recoiled from the blow, even if she most definitely didn’t feel it. She whispered, afraid that Chrysalis would hear her. “It just slipped inside with all the crazy turbulence!”

“That’s the most ridiculous thing I ever heard!” Adagio jabbed her sister’s chest; it was like punching a brick wall. “Stop lying to me!”

“I’m serious! I was busy fucking your boobs,” Aria was slightly rocked by her sister’s vengeful buck. “and before I knew it I was in her! I took it off as soon as I realized. I mean after I got over how amazingly tight her pussy is… was.”

“You are disgusting!” Adagio managed to grab one of her sister’s ears, dragging her massive head to her level. “This won’t happen again, do you hear me?!”

“Hey, I told you!” Aria winced in pain. She actually didn’t feel the ear pull at all, her reaction only ingrained in her mind from all the times Adagio had lectured her. “It was an acci…”

“Touch Sonata or myself again and you will have another unfortunate accident!” Adagio hissed, looking her sister dead in the eyes. “Am I clear?!”

“Crystal.” Aria meeped, cowed by her tiny sister. She breathed in relief when the fuming little pony looked back to Chrysalis and their sister, letting go of her ear.

“Oh my lord…” Adagio held the sides of her head, watching in abject horror as more and more siren seed sprayed from Sonata’s insides. “How much did you put in her?!”

“Dunno.” Aria said, fascinated by her production despite herself. “Felt like a lot.”

“Wait… Ooooh this is bad.” Adagio started to pull on her drying mane, the hairs starting to puff up. “With Sonata in heat…”

“What?” Aria looked at her panicking sister with confusion. “It’s not like sirens and ponies are compatib…”

“Tell me you didn’t directly use Chrysalis’ magic to grow your dick!” Adagio grabbed her sister’s chin, looking her in the eyes again. “You only used your own transformation magic, right? You weren’t stupid enough to use changeling queen magic to grow your thingy, right? Not when changeling queens can knock up anything that moves with their own young, a trait that you could have easily absorbed. You wouldn’t do that, RIGHT?!”

“…” Aria looked frightened, thinking about her magically altered siren sperms assaulting Sonata’s womb. “Fuck…” Her face fell with fear but her body responded in a very different way. Aria’s huge cock sprouted from its pocket, jabbing her sister’s cheek.

“Gah! Keep that thing away from me!” Adagio slapped the offending organ out of the way, only for the length to swing back and hit her jaw.

“I can’t help it!” Aria grabbed her dick, trying to put it back inside. The stimulation only made it worse. After a while she just gave up, her dick quivering at full mast. “You don’t think it’s going to happen, right?” Aria rung her hooves worriedly. “I mean, with all the spunk Chrysalis is putting in her there’s no way one of my little Arias could… Right?”

“Maybe not...” Adagio looked back to the coupling pair, Chrysalis dismounting with a satisfied expression. “But we have to be sure.”

“What, you have an idea?” Aria asked desperately. “We can’t tell Queeny, she’d kill me!”

“We have to clean Sonata’s insides, drain her out completely.” Adagio winced, thinking about the task ahead. She looked away as Chrysalis pressed her enormous tongue into Sonata’s pussy, the gaping tunnel brimming with thick seed. “I’ll distract Chrysalis and you get all of your disgusting fluids out of your sister. Your tongue should do the trick.”

“Wait, you’re saying I get to… I mean I have to eat her pussy out?“ Aria whispered, blushing. The sound of Chrysalis’ tongue thrashing around Sonata’s filled honey-pot made her cock quiver in anticipation.

“I can see how distraught that makes you.” Adagio winced, avoiding getting slapped by her sister’s jerking cock again. “As long as her womb stays open you’re saf…”

“YES!” Chrysalis cheered suddenly, her tongue retracting into her mouth. She hugged a dazed Sonata to her chest. “It’s sealed! We did it! Our foals are going to be beautiful!”

“Yaaaaay…” Sonata said weakly, before passing out completely.

“Yes!” Chrysalis started to buzz around, holding the unconscious pony in her arms. “Yes yes yes yes!” She danced a sensual tango with her sleeping partner. “Yes!” She did a loop with her lover in tow. ‘Yeeees!” She sat on her haunches and brutally impaled Sonata’s limp body on her cock, humping into her in celebration. “Yes! *hunf* Yes! *huunf* YES!! *UUUUH*”

Adagio and Aria shared a look of dread as Chrysalis fucked their passed out sister, Sonata’s limbs flailing with each thrust as the changeling came explosively. After a rough hump the sleeping siren fell flat on her face, the changeling instantly throwing herself over her unmoving form. Chrysalis had to press her barrel on the ground, her hips twerking as her cock rammed into Sonata’s prone body. The two sisters didn’t know for sure what was growing inside Sonata’s womb, changeling or siren, and they would have to wait to find out.

Aria was already thinking about where she would disappear to in case the worst happened. Maybe she would go back to the human world, or to Tartarus, or even the moon. Nothing seemed far enough to avoid the changeling’s wrath. But in the mean time she would enjoy herself, starting with reafirming her claim on a certain changeling queen. She ignored Adagio’s disgusted look as she started beating off, watching Chrysalis ram Sonata into the ground. If these were to be Aria’s last mouths, she would not spend them fearing for her life. Resolute, the huge siren flew straight to the changeling, eyes locked with her jiggling rump, preparing to give her own personal broodmare the ride of her life.

Epilogue: Six months, two weeks, five hours and three seconds later.

Aria flew through the hive at break-neck speeds, the cavern walls just wide enough to accommodate her great bulk. Her fins scrapped against the green changeling resin from time to time, but she didn’t slow down. Sweat kept running down her brow, dripping into her panicked eyes as she barreled into her sister’s private chamber. Adagio looked at the proud hippocamp fly around her room like a dog chasing its tail, one of her eyebrows disappearing into her clean poofy mane. She didn’t move from her great canopied bed, lounging on her side, but she did pull her silk linen to cover her swollen breasts. She had a laced pure cotton doily folded on her side, the picture of a smiling moon made of crushed gemstones woven into the fabric.

“What did you do this time?” Adagio asked impassively. “Please tell me you didn’t try to set her throne on fire again.”

“No!” Aria rounded on her sister, panic in her eyes. “It’s time, it’s coming, SHE’S ABOUT TO BLOW!”

The outburst caused the sleeping black foals surrounding Adagio to squirm, some of them starting to wail softly. The pony shot her sister a dirty look, then cooed softly to her children, using just enough of her pendant’s powers to lull her first borns to a peaceful sleep. The dozen little changelings all curled up against her fur, searching for their mother’s warmth, except one who stood up groggily. Adagio ran a loving hoof through his orange frill, the foal stumbling on his stubby black legs to reach her stomach. The mother didn’t hesitate to uncover her udders, letting her little one nurse to his heart’s content.

“I am so glad I don’t have those anymore…” Aria mumbled, wincing as the little changeling suckled noisily. “Doesn’t it hurt? They’ve got those sharp little fangs and all.”

“They are very careful, they wouldn’t hurt me.” Adagio smiled, nuzzling her charge. The foal opened his bright yellow compound eyes, gazing at his mother with unconditional love. “It has been two weeks, and I still haven’t felt one little bite.”

“Mine bite me all the time.” Aria did a loop, chuckling. “I wonder why…”

“It’s because yours are a bunch of ruffians.” Adagio said, frowning. “The fact that you have so many doesn’t mean you have to neglect their education.”

“Hey, I take care of my spawn!” Aria huffed.

Her assertion was punctuated by a strident scream. The sisters turned to the chamber’s entrance, and the next instant a bunch of giggling and shouting young changelings stampeded through the tunnel outside Adagio’s room, their lavender fins and neon-purple eyes blurring as they raced past the door. They were of various sizes, the biggest were just under the size of a young colt or filly, the smallest just a little larger than Adagio’s foals, clinging to their brothers’ backs. The cohort streamed past noisily for almost a minute, before only the echoes of their excited shouts could be heard. Adagio and Aria exchanged glances, the older siren snorting irritably.

“What?” Aria tilted her head. “They are just having fun!”

“Hooligans.” Adagio huffed. Her frown melted into a kind smile as her foal chirped softly, milk running down his muzzle. “Mine will be educated and sophisticated, thank you very much.” She grabbed the expensive doily and dabbed it on her child’s snout, cleaning him gently.

“You do know they don’t really need that gross stuff, right?” Aria piped up. “I only feed my kids with love and they don’t complain.”

“Chrysalis says that they still benefit from maternal milk.” Adagio cooed softly to her young, letting him curl up against her barrel. She embraced her foal with a careful hoof, keeping him close as he fell asleep. “If there is one thing we can trust that bug with, it’s the health of her children.”

“True, she really loves all her little tykes. Remember when I spawned for the first time?” Aria reminisced, flying on her back. “Never thought Queeny could cry so much from happiness. It was the same thing with you too.”

“That’s nothing compared to when she birthed yours.” Adagio smiled. “She was quite hysterical when the contractions started.”

“Yeaaah.” Aria beamed at the memory. “One moment she’s trying to strangle me, accusing me of doing this to her. Then the first Aria junior pops out and she’s trying to kiss me, thanking me for doing this to her.”

“Did she ever agree to let you… You know…” Adagio looked unconformable, her ears pressed against her skull. “Do the thing again?”

“She said, and I quote: ‘I’ll bear your pups again if you stop spoiling the ones we already have, you bitch.’” Aria shrugged. “I don’t see what I could do better.” She blinked as the screaming column of purple highlighted changelings rushed by the door once again. “Hey! Keep it down!” She barked. Her children responded by yelling even louder, then running faster. “See? I try.” Aria said with a satisfied smile.

“And to think this is only the beginning…” Adagio sighed, nuzzling a foal that was running in his sleep. She smiled as he calmed down. She then flicked her chin to Aria’s rounded belly. “This is what, litter number seven already?”

“I think so?” Aria rubbed her swollen stomach. “It’s pretty hard to keep track off.”

“Well your gestation period is only a month long, being a siren an all.” Adagio kissed a yawning foal. “I’m not surprised the bug is all over you constantly.”

“You could transform too, that way you won’t have to wait so long to have new babies.” Aria floated closer, rubbing her massive snout on her older sister’s tiny head. “I miss being the same size as you two.”

“I don’t know...” Adagio frowned. “I don’t mind being a pony, and it just feels…” another foal chirped, then crawled towards her belly to nurse. She gave her child a motherly smile. “It just feels right.”

“Well I guess it’s up to me to build our numbers up. Good thing I spawn more than twenty at a time.” Aria groaned. “I had to wait three months for Queeny to deliver and now she won’t let me knock her up again. At least not until I do something about all the Aria juniors destroying the hive. That’s gonna take a long while, and she’s been blue-balling me for more than three months already. And you sure took your sweet time with your babies, didn’t you? I mean, six months? For just twelve?”

“The bug said that’s the perfect gestation period for a pony with changeling foals, be thankful that it wasn’t eleven months like usual.” Adagio grumbled. “And she’s already trying to get to me again.” She nodded to a small doorway, leading to her personal bathroom. “Can you believe she tried to jump me in the showers when I left my foals for the first time?”

“Did you distract her with your tits?” Aria laughed.

“No.” Adagio snorted. “I bucked her in the balls. It was funny how she did her best not to scream to avoid waking up the children. She learned her lesson for now.”

“Oh, that’s weird.” Aria smiled like a shark. “She loves it when I’m the one busting her nuts. She cums super hard too.”

“You’re disgusting.” Adagio grimaced. “In the meantime I hope Sonata’s okay, she’s already two weeks late…”

“Oh CRAP!” Aria launched into the air, ignoring Adagio’s shushes. “I forgot!”

“What?” Adagio whispered fiercely, trying to get her sister to pipe down.

“Sonata!” Aria hissed back, circling the bed. “She’s gone into labor!”

“Oh, finally. I was starting to worry…”

“Have you seen how huge she is?!” Aria pressed her muzzle against her sister’s snout. “And changelings are so small; so either there are at least twenty foals in there…”

“Or a few sirens.” Adagio winced. With the magic protecting their pregnant wombs there had been no way to see what Sonata was carrying, but the kicks she felt sure seemed a little strong for changeling foals.

“Queeny is gonna kill me!” Aria shout-whispered. “Or at least she’s gonna chew on my dick like it’s beef jerky!”

“She won’t kill you.” Adagio hissed. “Not when you are full with her foals. But she will rip out your disgusting phallus, yes.”

“But I wanted to fuck her again!” Aria whined.

“We’ll just have to wait and see.” Adagio laid down her head amongst her children, her ears perked up.

*******************

Deeper in the maze-like hive, Chrysalis was holding a panting Sonata in her gentle black hooves. The wincing pony was lying on her back on a specially prepared bed, her hind legs held apart by two arms of hardened resin. The Queen was sitting on her haunches next to her suffering lover, trying her best to help. The changeling’s magic was flowing all over her mate’s bulging frame, soothing her pain, helping her relax. The siren’s breaths were ragged, her face red and strained, her chest rising and falling quickly as the red pendant embedded in it shone brightly. Suddenly Sonata clenched her teeth and squealed in pain, her body seizing as Chrysalis hugged her tight. The contractions were coming quicker and quicker; the pony would deliver on the hour. But instead of being euphoric the changeling couldn’t help but fret for her lover’s well being. She had been right all those months ago; Sonata’s hips were too narrow, even for foaling changelings.

“I’m sorry my love…” The queen whispered. “I shouldn’t have done this to you.”

“I’m fine Chryssi.” Sonata lied. “It’s just a little *Hnnng* … a little rough.”

“I swear to you, I will never put you through this again.” Chrysalis vowed, kissing her lover’s neck.

“Wait, what?” Sonata panted, her eyes widening when another contraction rocked her body. “Aaaah, holy molly that hurts…”

“I won’t breed with you again.” Chrysalis clarified. “Not until you return to your hippocamp form.”

“But I like my pony body!” Sonata whined, hiccupping from a kick in her womb.

“You are too small my love.” Chrysalis murmured, pressing her snout in her ear. “But if you wish to stay this way I understand. One brood from you is enough for me; we can still make love without me hurting you…”

“But I want you to hurt me!” Sonata huffed, as if explaining the obvious. She winced with another contraction. “That’s the whole point of me staying a pony!”

“Wha…”

“So you can wreck me with your giant cock!” Sonata cried, euphoria making her tongue flop from her mouth. Her body jerked with unprecedented agony.

“But you would get pregnant again!” Chrysalis said, flabbergasted.

“Yeah! You’ll fill me up good, won’t ya?” Sonata slurred, looking half delirious from the pain.

“You’ll have to go through all of this again!” Chrysalis’s eyes began to shine, tears threatening to spill. “Aren’t you in pain?”

“Oh yes…” Sonata rattled. “I hurts so goooooood!”

“Uh?” Chrysalis froze, letting her mate writhe against her. “Are you… enjoying this?”

“Like you wouldn’t believe!” Sonata’s face was contorted in an obscene grimace of pleasure. “I want more!”

“I knew you had developed a liking for some rough riding…” Chrysalis said, regaining her senses. “But I hadn’t realized you had become so… debauched.”

“Shut up and pinch my nipples!”

“I miss my innocent little Sonata.” Chrysalis murmured, but she obeyed anyway, her magic tweaking Sonata’s swollen teats gently, milk dripping on her thighs. “She was so sweet and uncorrupted…”

“Hey, I’m still here,” Sonata said kindly between pants. She lovingly brushed a hoof against her partner’s muzzle. “I’m still your ‘little Sonata’, I still like rainbows and kitties and everything, you know that.”

“Oh yes, I do know that…” Chrysalis thought about their bedroom, awful posters covering the walls, cats everywhere, bunnies, flowers… The chamber was more pink than green! Chrysalis would never live in such a room if it wasn’t for the bubbly pony she shared her life with. She was still innocent and pure… Except when they were fucking like wild animals. Then Sonata turned into a raging masochist with a potty mouth to rival Aria. The contrast was striking. “I just didn’t think you would enjoy the birth of our children in such a way.”

“You sound disappointed.” Sonata breathed, enjoying the strongest contraction yet. “But what’s this?” She used her tail to stroke the large cock bumping against her side, the length harder than rock. “You didn’t get one of these when it was Aria or Adagio’s turn to give you little changelings. Am I so special?” Sonata panted, already knowing the answer from the many nights they had spent just holding each-other, kissing and talking.

“Don’t toy with me.” Chrysalis hissed, grinding her cock on Sonata’s flanks.

“Or what, are you going to punish me?” Sonata breathed huskily. This was the sort of game they often played, most of the time ending with Chrysalis pounding Sonata into a wall.

“Your little cunt already has enough on its plate.” Chrysalis ground herself harder, the scent of Sonata’s excitement driving her crazy.

“I do have another hole you could use…” Sonata sang, hiccupping again.

“You have enough difficulties breathing, I won’t…”

“I wasn’t talking about my mouth.”

They both stayed silent, letting the proposition hang in the air. Sonata kept moaning with bated breath, her body preparing for the upcoming ordeal. Chrysalis’ thoughts went spiraling out of control; she had always rebuffed Sonata’s pleas for trying alternate routes of penetration, afraid she would hurt her love. But the pony was now as dilated as she would get. Her cock throbbed intensely as she slowly accepted the idea.

“This is going to hurt.” The changeling said, head spinning with lust.

“I hope so. Don’t hold back.”

“Your hips, they are so narrow…”

“Well you better stretch them so I can push out our babies.”

“You are unbelievable…”

“Thank you. Now fuck my asshole before I pass out.”

Chrysalis scrambled to position herself between Sonata’s open thighs. From there she could see the usually tight slit gaping open, juices running freely, both prenatal fluids and Sonata’s arousal. The river ran over Sonata’s puckered star, her little doughnut quivering with anticipation. It looked so small and fragile, so appetizing. Sonata suddenly squirted, the changeling directly in the path of the pungent shower. The mixture hit Chrysalis’ nostrils like a haymaker, and before she knew it she was rearing up, mounting her love.

“Careful with the babies!” Sonata squealed, protecting her belly with her hooves as the changeling clambered on top of her.

Chrysalis shook her head and shuffled forward, placing her black forehooves on each side of Sonata’s body. She took great care of not putting any pressure on her round stomach. The magic shielding her womb could withstand anything, but they were taking too many chances as it was. Sonata relaxed, lying on her back, as they both stared into each other’s eyes. Chrysalis’ cock instinctually searched for her soaking cunt, but the changeling surrounded the jerking length with her magic, angling herself lower. They both shuddered as the blunt head made contact with her pouting little hole, Sonata squirming as she realized just how much of a stretch this would be. Chrysalis pressed herself more forcefully, but the siren’s ponut stayed resolutely constricted. Huffing the changeling drew her hips back and unleashed her magic, reason leaving her mind.

“Uh, on second thoughts maybe we shouldn’t…” Sonata’s hesitation was cut short as her lover whinnied and humped forward.

She screeched as Chrysalis’ huge cock barreled through her anus, magic preventing any tearing but doing nothing for the searing pain it caused. Sonata’s eyes rolled back as she experienced the most intense orgasm of her life. If she had though Chrysalis’ girth was uncomfortable in her pussy, it was nothing compared to the delectable agony she was now being put through. Her lover’s cock sank a few inches then stopped, but instead of drawing back and thrusting again Chrysalis just jumped into her, hilting deep inside.

Chrysalis had imagined that Sonata’s ass would be very similar to her pretty cunt, she had never tried anal before. So when her cock sunk into her love’s puckered hole she couldn’t help but stop herself mid thrust: the walls were nothing like she expected, the tightness almost painful. Where Sonata’s pussy was velvety and welcoming, her bowels were rough and dry, the walls irregular and grooved. And It was hot. Hotter than Chrysalis thought possible. If plunging into Sonata’s cunt was like putting her cock into a pot of honey, her ass felt like when she grinded her length on the covers of their bed, whenever they decided to have a little heart to heart and not bang like animals. And Chrysalis decided that she had to have more of this incredible sensation. She shuffled her hooves then sprang forward, burying her cock to the hilt.

Both changeling and siren screamed in excruciating pleasure, Sonata stretched way above her normal limits thanks to the magic, Chrysalis squeezed more tightly than even Aria had ever managed. The changeling soon began to thrust jerkily, each motion agonizing for her and for her love. But the pain was slowly ebbing, each new hump taking away the discomfort as they both got used to this new sensation. The two anal virgins panted in unison as Chrysalis’ cock spurted a generous helping of precum, resolving the dryness issue. The next hump was much smoother, but the siren’s ass still squeezed with an iron grip, the grooved walls sticking to the intruding length like a fleshy suction pad. Each and every motion were both blissful and painful at the same time, Sonata’s powerful anus constricting around Chrysalis’ cock without mercy.

Chrysalis retracted her length until only her flaring head stayed inside, enjoying the squeezing from the siren’s sphincter, then plunged as hard as she could. The lack of cervix against which she could hilt made her thrust go much deeper that she anticipated, her mushrooming head finding itself lodged into the tail end of Sonata’s intestines. The changeling’s balls collided violently on the bed frame, carried by the unstopped hump; sperm brewed vengefully as Chrysalis’ orbs shot into her body. Chrysalis felt her orgasm come at a gallop, and she collapsed on her lover, careful to sustain her weight and not push on her swaying belly. Sonata squealed as she came continuously, her pussy squirting onto the changeling’s belly, and she climbed to new highs when the love of her life brought her black muzzle to hers. At first the siren thought that she would get a visit from mister tentacle tongue, or Lenny as she liked to call it, but Chrysalis contented herself with rubbing her snout against her nose, a chaste eskimo kiss while she pounded her love’s ass into oblivion.

The changeling’s semen rushed into her shaft, intent on filling this new hole with its potent scent, but the onslaught came to a sudden stop. Sonata’s anus was so tight that it formed a restricting band around Chrysalis’ cock, the sphincter denying the changeling her orgasm. Chrysalis snarled at the feeling of her pleasure being kept one breath away from fruition. No matter how much she pushed her cum was too dense to pass through Sonata’s tight seal. Screaming in frustration she tugged at her length to get it out of the constriction sheath, but nothing happened. Sonata was holding her hilted by the sheer force of her anal walls, denying Chrysalis the luxury of escape but also taking away her right to cum. Chrysalis whined as she was tortured into madness, her semen packed at the base of her cock, only a few drops crawling past Sonata’s puckered hole.

Chrysalis’ wings started buzzing frenetically as she tried to extricate herself from the tortuous situation, her flare slowly dragging Sonata’s walls with it. The changeling’s compacted spunk traveled a laborious path down her length as her dick emerged lethargically, the siren’s walls trying to suck it back inside. The flare finally reached Sonata’s powerful anus, and Chrysalis tugged at the last resistance with the energy of desperation. Her semen was just inches from release, but the siren’s sphincter was still holding it back. Chrysalis screamed in frustration as she jumped back. Her flare finally was freed from the crushing confines with a loud *POP*, a torrent of spunk spraying into Sonata’s gaping asshole instantly.

As her puckered hole sealed itself Sonata came down from her unbelievable orgasm, and she felt the changeling’s gooey treat splash against her nethers. She whined softly in protest and Chrysalis was instantly at her side, presenting her spewing cock. Sonata smiled as the thick spunk splattered against her face, before she sealed her lips around the spurting cock hole. She swallowed urgently, now very proficient at dealing with her lover’s mammoth ejaculations. Chrysalis enjoyed watching the bulges go down Sonata’s throat as she gulped down her seed, the insatiable siren clamoring for more as her tongue teased her urethra.

Not even a minute had passed before Sonata unexpectedly released the changeling’s spurting cock and hunched over, wincing in pain. Chrysalis suddenly remembered what they were here to do. The changeling scrambled in a panic, her magic cleaning her lover thoroughly; she could always cover her with more spunk later. When everything was squeaky clean Chrysalis embraced her love again, waiting for the right time.

“They are coming…” Sonata mumbled through her agony.

Chrysalis was instantly between her legs, her magic ready. She watched with bated breath as Sonata’s dilated labia undulated, before the head of her first born appeared. It was a minuscule black foal, worryingly small even for a changeling newborn; in another hive he would have been deemed too weak to be useful. But to Chrysalis he was the most perfect little baby she had ever seen, and the queen started to cry uncontrollably. Chrysalis held the infant carefully as it emerged, his electric blue eyes opening for the first time, blinking owlishly. She carefully severed the umbilical cord with a quick bite, her magic healing the small wound as her precious child started to wail plaintively. Chrysalis kissed his little blunt horn, nuzzling his itty bitty azure frill. She smiled as the wails subsided, then did her best to clean the little foal, being as gentle and caring as possible. Sonata groaned and Chrysalis’ eyes widened when a second black head appeared, coming too quickly: her anal romp had definitely pried Sonata’s hips open, she would have to heal them after this was over. Chrysalis quickly bundled the undersized child in a cocoon of warm resin, before levitating him towards Sonata’s reaching hooves. The siren embraced her first born, cooing, her aura saturated with love. Chrysalis hoped it would be enough nourishment to save the little foal, he was so fragile... She was relieved when she delivered the second foal, a normal sized little changeling this time. She washed, bundled, and lovingly kissed Sonata's second child just like the first.

The process repeated itself seven more times, a decently sized litter of nine. Chrysalis thought that her heart would burst from pride and love, watching her lover cradle the many changeling foals, softly chanting to them with her beautiful siren voice, pendant shinning softly. But something was wrong. Sonata’s belly was still a little swollen, like she still had two or three foals inside, but if that was the case they should have been pushed out already. The painful thought of having stillborns made Chrysalis wince: it had never happened to her before, and she knew her heart would be irremediably shattered if this was the case. Carefully, she sent her magic into Sonata’s now unsealed womb, trying to help her last children, show them the way out.

She was astonished when she found not a couple of changeling foals, but something much larger. She quickly realized that Sonata had been carrying a siren spawn alongside the changeling foals. This was unprecedented: no race had ever produced anything else than changelings during the nuptial flights. The thought of having a siren daughter made Chrysalis’ heart race with excitement, and it was with great care that she helped its greater bulk through Sonata’s passage. Finally Chrysalis could see the minuscule siren’s snout, blue like her mother. The changeling was impatient to see if some of her own features had been transferred to her unlikely offspring, and it was with the greatest care that she helped the newborn siren slide free, looking at the beautiful little miracle, her heart soaring when she saw that it was a cute baby girl.

The newborn siren had her mother’s predominant colors, blue scales all over her little body except the armored plates of her belly which were a deep lavender, and a tiny little red pendant in her chest. She had lovely little purple fins, and when she opened her eyes Chrysalis smiled at her precious purple irises… Wait purple? PURPLE?! PURPLE?! Looking closer the changeling started to see familiar features: the shape of the little siren’s snout, the cut of her fins, the frilled end of her tail… And above all a cute dimple that made the siren look that she was always frowning. Those were not Sonata's features. Those were definitely not her own features. She had seen that dimple in only one other being, in her pony form or her siren form. This was not her offspring. This was her rivals spawn. This was Aria’s ultimate insult.

Chrysalis started to shake with rage, but she was distracted when the newborn siren giggle-snorted, reaching her little blue hooves towards the changeling’s snout. The little thing smiled, a smile oh so similar to Sonata’s. It made Chrysalis' hearth throb painfully, knowing what she had to do. The changeling ways were set in stone: children from rivals were to be terminated, without mercy. They could be a threat to her own progeny. Suddenly she thought about Sonata's first born, so weak and small. Chrysalis realized she had just found the cause for his stunted growth: the siren intruder had parasited him, stealing the energy that should have been his. And suddenly killing the little siren wasn't so hard. The changeling opened her jaws, fangs dripping and ready to sink into the newborn. Chrysalis snarled then struck, jaw closing around her prey. She sunk her teeth into the soft flesh and ripped it apart, blood spraying into her mouth.

The little siren shrieked weakly, but she soon quieted down as Chrysalis healed the umbilical cord she had just bitten through. The changeling cleaned the siren like she had done her own, even kissing the bastard child with reluctant love. She was completely incapable of hurting one of Sonata’s children, even if it wasn’t one of her own. She thought about using her magic to change the malleable newborn’s colors, but she had to admit that she looked very cute as she was. She levitated the little siren to her mother, Sonata gasping when she saw her.

“Oh my gosh!” Sonata gushed. She carefully put the changeling she was holding with the rest of its brethren, lying curled against her side. “I thought we only would have changelings!” She peppered the giggling siren with kisses, hugging her lovingly.

“Yes.” Chrysalis said curtly as Sonata embraced the giggling little siren. “This is unprecedented.”

“Wow she’s so precious! She looks just like me!” Sonata cheered happily. Then her head jerked back, surprised. “And just like… Aria? What?” Sonata’s surprised look slowly morphed into a cringe of disgust as she understood the implication. “That’s impossible!”

“That day in the pool chamber, when you were under us.” The changeling hissed angrily. “You became so loose all of the sudden. It was that bitch!” She snapped her jaws at her own stupidity. “She even smells like your sister!” Chrysalis snarled despite herself, tensing up. She winced when Sonata shot her a panicked look, holding onto her child protectively.

“What are you going to do to her…” Sonata whispered, frightened. Her pendant began to shine dangerously.

“You know me,” Chrysalis rumbled with a straight face. “what do you think I’m going to do?”

“You’re gonna eat her?” Sonata squeaked, almost inaudibly.

“No.” Chrysalis relaxed her stance, then smiled. Sonata instantly became more at ease, used to reading her companion's mood. “I’m going to care for her like I will care for all my other children, and do you know why?”

“Because she’s my kid?” Sonata said gently.

“Because she is our child. Us two. No one else.” Chrysalis proclaimed. “Because I am yours, and you are mine.”

“What about Aria?”

“Not a factor.” Chrysalis growled. “My mate. My child.”

"For realsies?"

"Yes."

“Hmm…” Sonata tilted her head, then smiled. “Hey there, Chryssi junior.” She cooed softly, nuzzling the little siren. “Welcome to the family! Say hello to your mommy.” She held out the newborn to Chrysalis, who smiled despite herself and leaned in, rubbing her snout on her purple belly, making the child giggle again.

“Are you really naming her Chrysalis?” the changeling snorted, strangely not opposed to the idea.

“Junior!” Sonata cheered. She then pouted. “If you would just let me name all the others too…”

“Changelings are named after the initials of their mother, their rank of birth and then their iteration.” Chrysalis shook her head.

“That’s not fun!” Sonata gently lowered the siren amongst her smaller brothers, and then picked her minuscule first born carefully. “I don’t want to call him SD01-00, I want to call him Allegro!”

“If you want you can give our children nicknames.” Chrysalis sighed. “Adagio already gave all our foals one. But don’t forget that before long you will have more children and grand children than you could imagine. Trust me, the changeling system works best.”

“Well I’m still naming them.” Sonata beamed, the changeling chuckling.

She and Chrysalis exchanged a loving kiss, bathing their children in love. The changeling then levitated Sonata towards the nursery bed, where she would be able to let her children suckle while she recuperated from the ordeal. The foals and baby siren followed, floating in the emerald cloud as the cocoons around the little changelings dissolved into thin air, letting them able to crawl around. The pony mother noted that Chrysalis took extra care to position the littlest foal nearest her swollen breasts; she would take extra care of Allegro. Sonata expected the changeling to join her but Chrysalis marched purposely to the nursery exit.

“Where are you going Chryssi?” Sonata called groggily, quickly falling asleep.

“I’ll be right back my love.” Chrysalis glanced back with a smile, but the siren noted that her eyes were once again completely black. The shark-like gaze made Sonata exhale in exasperation. “I’m just going to kill Aria and I’ll come back.”

“Again?!” Sonata mumbled, eyes closing. “You say you're going to kill her at least twice a week, it’s getting old.”

“This time I mean it.”

“Sure.” Sonata slurred, instinctually holding her thighs open to let her little rascals nurse. The newborn siren was more interested by Sonata’s red pendant, rubbing her snout on its surface. “Just tell her to stay away from Junior after you’re done playing, I don’t want her near our little girnnrrrrrh” Sonata fell soundly asleep, snoring softly.

Chrysalis gave her mate one last loving look, then she lunged and raced like a cheetah, tearing through the hive, her magic locating her prey.

*******************

Back in Adagio’s chambers Aria was gnawing on her own hooves in worry, under the unamused gaze of her sister.

“Think it’s over?” Aria asked, rocking back and forth.

“I don’t know.” Adagio sighed. “Being so small, Sonata could have some issues giving birth. Especially to a siren.”

“Don’t say that!”

“Relax, if that had happened I’m pretty sure we would have heard…”

“ARIA YOU BITCH!!!”

“Oh, there it is.” Adagio said calmly. She didn’t bat an eye as her sister zipped out of her room, fleeing for her life in what had become a regular occurrence. Adagio sighed and went back to care for her little foals, smiling as she nuzzled each and everyone of them. She may still dislike the changeling queen, but she had to admit that the little drones were now the most important thing in her life. Just next to having her revenge of course.

Her ears perked when she heard Aria scream like a little girl as Chrysalis howled, followed by the ovations from the army of little Arias, drawn to the chaos like moths to a fire. The little changelings always enjoyed their mothers' brutal fights, taking sides, cheering for one or the other. They fueled the conflict with their magical voices, all the while absorbing Chrysalis and Aria's energy, leaving the both of them exhausted before they could really harm one another. Then the herd of purple changelings would crowd around the downed combatants, lovingly snuggling with their passed out mothers. It was the only time they were quiet. Adagio sighed irritably, but the presence of her children soon calmed her down. Smiling contently she closed her eyes and hummed a lullaby, finding peace amongst her foals, drowning out the distant murderous roars, cries for mercy and cheers for blood.

One particular high-pitched scream was heard all the way to the surface, startling a sleeping blue jay. The bird twittered and flew into the rosy sky, the sun beginning to rise over the horizon. The land slowly awakened to a beautiful new day, ignorant of the impending disaster brewing under the earth. The hive would grow strong and numerous, the uneasy alliance of changelings and sirens announcing Equestria’s inevitable doom. But the peaceful nation wouldn't go down without a fight. A group of ponies were already doing their best to prepare for Chrysalis’ eventual return, warned by a drone trying to do the right thing. But that’s another story.
