Nuptial Flight

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.
