You Knew This Was Coming (Non-Canon)
You Knew This Was Coming
Dusk's cheeks burned with embarrassment. Cadance had sat herself down on the bench at the train station and instead of letting him sit down next to her, she went a step beyond. She'd wrapped her hands around Dusk's broad, femmy hips and heaved him down onto her lap, sitting him on her legs like a mother and her child. This would have been embarrassing enough on it's own, as a twenty year old adult, but what made it worse was that he was a prince.
There were people staring at him, snickering as Cadance snuggled into him and refused to let him go. He was a royal, a public figure, being made to look like a coddled little child in front of the entire public. He looked back at Cadance, opening his mouth to protest, only to have her shoot the most beautiful, innocent smile he had ever seen grace her gorgeous features. His ears flattened against his skull, a weighty sigh billowing from his maw as he turned away from her.
Her smile had melted him, probably done intentionally, but she seemed too happy for him to even consider moving away from their snuggle-session. He relaxed his body, leaning back against Cadance's enormous breasts and feeling the faintest hint of her baby-bump against his own back. The foal had been growing healthily, from what they'd heard. She'd had her three-month check-up and was told that it had and would continue to be smooth sailing up until her due date, if the current situation was anything to judge by.
They didn't know what gender it was, had to wait another month before finding that out, but the fact that the foal, his foal, was growing as healthy and happy as it was made him feel warm inside. It brought on a sense of paternal pride that he'd carried out the only real reason any creature exists and had done it with a 'prime specimen'.
"You wanna fuck when we get home?" Cadance whispered into Dusk's fur tipped ear, keeping her voice low enough to hide the lewd conversation from the rest of the world.
Dusk's eyes widened in shock, looking back at Cadance with a disbelieving expression as the pink princess' sexually-charged expression sent a bolt of arousal through his body, specifically, to his loins.
"Cadance..." he muttered, feeling his cock begin to swell with unwanted excitement. "Gleam's coming home... we can't do that."
"Why not?" Cadance asked in a hot tone, gently dragging her tongue along Dusk's neck, this being an action that was caught by several other ponies. "You against the idea of a threesome?"
"Cadance, please stop talking," Dusk said, glancing down and noticing that his own bulge was visible in his pants, swelling out against the side of his leg and getting several shocked looks from passersby.
"I'm down for it," she sniggered, gliding her hand against Dusk's bulge and squeezing it gently. "What'd be a better way to welcome her home after a long, hard war than a nice, wet fuck?"
"Cadance," Dusk said in a begging tone, heart pounding, face red as a tomato, and cock throbbing in his pants, several ponies nudging each other and pointing at the two of them.
"Are you getting excited, Dusky?" she giggled, fingers gripping his tightly-wrapped cock. "The idea of ramming it home inside your big sister getting you all hot in the panties?"
Dusk gritted his teeth in sexual frustration, his mix of embarrassment, arousal, and anger at Cadance's teasing being almost too much for him to handle.
"If it's too much for you... I can help you take a load off, right here," she grinned, licking the inside of her his ear while continuing to massage his cock. "They're already staring... why don't we give em a show? Let Gleam's train arrive just in time to see you give me a cunt full of cream?"
That broke him.
He grabbed hold of Cadance's dress and teleported both of them, focusing on a back alley he'd seen on the way to the train station as their destination. They reappeared instantly, Dusk turning around on the much larger, grinning Alicorn as she stared down at him in victory, knowing she'd gotten him riled up enough to get nasty.
He gripped the chest of her dress, using a brief burst of magic to give himself incredible strength, shredding her dress straight down the middle and throwing it aside, leaving Cadance stood in her underwear, exposing her sleek curves and buxom form to the alley around them, and anyone that would poke their head down it.
"On your knees," Dusk growled. "Now."
Cadance made no hesitation, showed no signs of a lack of willingness to continue to discomfort. She instead giggled playfully, getting down onto her knees and resting her hands on her thick, fuckable thighs while waiting for her next command. Dusk tore his own pants open, snapping his belt, tearing his zipper, and ruining the black dress pants he'd worn just for the occasion. He pressed the entire length of his massive cock against Cadance's muzzle, radiating heat through his enormous, fifteen inch shaft as he stared down at her.
Cadance batted her eyelashes in a seductive manner, slowly opening her maw and exhaling quietly, the wave of heat flowing from her maw enticing and arousing Dusk even further. He wasn't gentle with her, nor did he take his time. The big pink harlot knew exactly what she was going to get if she riled him up at the train station, so he gave her exactly what she wanted.
He took a handful of her hair, gripping tight at the back of her head, before ramming his cock as deep into her gullet as it would go. The noise Cadance's throat made as it was forced to accommodate fifteen inches of forearm-thick cock was as arousing as it was guttural. The hot little whore wrapped her lips around his length, keeping them taut and tight as the small, femmy Alicorn began to fuck her gullet. All the power in his hips went into ploughing her mouth, thick trails of spit gathering around the corners of Cadance's mouth as Dusk hammered his cock in and out of her throat.
He could feel her windpipe stretching and bulging as his cock hammered in and out of it, seeing Cadance's eyes roll back, her fingers snaking into her panties and toying with her dripping cunt as his crotch slammed into her muzzle again and again. He was huffing heavily in a matter of moments, his fringe hanging over his eyes as he stared down at the pink slut currently pinned against the wall. The lines of spit spilled down her cheeks, slopping over her chin and down onto her breasts.
He was pumping pre into that mixture as well, leaking like a broken pipe into her mouth, feeding her the cum she craved so desperately. He ran a hand through his mane, slicking it back over the top of his head as best he could before dropping Cadance's mane, settling for grabbing both sides of her head as he went into overdrive. Fingers gripped tightly, curling around the back of her skull, as he rammed her head harder and harder onto his cock, teeth gritted and muscles aching with the exertion of his actions.
Cadance's moans were stifled and mangled, rendered almost inaudible by a mix of thick spit, cum, and cock blocking her windpipe as Dusk ravaged her whorish little mouth, eager to cum a litre of cum into her throat for every teasing little statement she came out with back at the platform. He'd lost count of his thrusts at this point, eyes merely fixed on Cadance's glowing orbs, her tits bouncing from the force of the drilling her tight gullet was getting.
The scent of her wetness, a smell as familiar to him now as his own cum, was wafting up from between her legs. She'd soaked through her panties, fingers coated in her lady-lube as she fingered herself vigorously. She was riding close to the edge of her own orgasm, moments away from opening her floodgates and cumming hard enough to knock herself unconscious.
Cadance got off on pleasuring other people. Said it was part of her 'princess of love' deal, that she could tap into the pleasure of anyone that ever stuck it inside her and experience their pleasure as her own. So it came as no surprise that her maw and pussy were drooling as much as they were from the sensation of her own tight throat. Dusk grinned in an almost dark fashion, seeing Cadance groan and twitch on the floor as he approached his own orgasm, cock slicked with spit and precum as it banged into the back of her mouth, sliding in and out of her clinging throat and blocking almost all of the oxygen.
Soon, however, they were both at their limit. Dusk came in her gullet and pushed Cadance over the edge soon after, pumping hot cum into her belly, swelling her up within a matter of seconds. Dusk pulled back slightly, wanting to make a mess of the pink whore, and allowed his load to spill out from her mouth. She did his favourite thing at this point: she let it happen. She made no attempt to drink it anymore, nor any effort to pull away and avoid the stream.
She instead remained on her knees, fingers in her cunt while the alabaster river of cum flowed out of her maw, dripping down her chin and spilling onto her breasts, the loud, glue-thick muck audibly slopping as it hit Cadance's pink tits, then down over her bra, and then onto her thighs. It pooled around her, leaving the unholy scent of sex on her, the floor, and the air around them as Dusk finally pulled out of her mouth, cumming the last of his load on her face as she slouched back against the wall.
Her pants were interspersed with laughs, a mix of the pleasure high and genuine amusement as Dusk stood there, staring down at her snow-white form with flecks of pink poking through her cum-coating. She took her fingers out of her panties, licking them clean before sighing in a relieved manner, looking up at Dusk with her hot, loving eyes before sticking her tongue out at him. She may have been the one covered in semen, on her knees, and in a dirty alley... but she'd won. He knew for a fact that this was what she'd planned from the get-go; frustrating him enough to fuck her in some kind of way, and her cum bath was her prize.
"You're so easy to play, Dusky," she giggled, getting up and wiping handfuls of cum off her, the practice looking like a large slate of snow falling off a roof as it splatted onto the floor at her feet. "Like a free fiddle... do you feel better, though?"
"I want your pussy," Dusk said, crossing his arms and glaring at her.
"Oh?" she asked in a surprised manner. "You still want more? My, aren't you greedy?"
Dusk reached down and ripped of Cadance's panties, casting them aside and pushing her up against the wall again. Cadance instinctively grabbed hold of his shoulders, eyes lighting up with sexual excitement and a sly, seductive smirk spreading onto her lips again.
"Gods, I love it when you get pushy," she giggled, looking him up and down as he pressed the enormous head of his cock against her dripping entrance. "You gonna put your pink little whore in her place?"
He didn't answer, instead ramming his cock as deep in her as it would go. Cadance's head rocketed backwards, her surprise causing her Alicorn strength to kick in as she smashed the brickwork behind her when her head struck the wall.
"Oh, Dusk!" she moaned loudly, wrapping her legs around his waist and stuffing his face into her cum-soaked breasts.
The larger Alicorn wrapped him up like a spider, limbs locking him into place and only allowing his hips to move as he fucked her dripping cunt. Her eyes rolled back immediately, his length, thickness, and speed feeling as good as it always did in her pussy, months and months of fucking him multiple times a day only making her fall more and more in love with his body. Her hand snaked around his waist, gently gripping his fat, femboy ass before two fingers made their way to his back entrance.
She felt his cock twitch and stiffen as she penetrated his asshole, fingers pushing into his tight cove, rubbing against his prostate and sending waves of pleasure through his body. She kissed him passionately, her taste mixing with his own and the remnants of his load, something Dusk had acquired a taste for in their more 'experimental' nights together. He swallowed it down with a shudder, pleasure running through his body as she could feel his heart hammering in his chest.
The poor little thing got nervous when he tapped into his gay side, but it was as adorable as it was arousing for her to push him further and further into it. Her fingers toyed with his boy-butt ever-faster, matching the bucks and thrusts of his titanic cock, the only thing about the stallion that brought an air of masculinity to him, as he moaned into her cum-stained mouth. His load coated both of them, clinging and grinding tightly against each other as the smell of sex over-powered both of them.
Dusk's girlish hips hit against Cadance's mothering loins, ramming his cock as deep into as it could go, nearly knocking on the door of the womb their child called home. Eyes closed and tongues lashing, the two of them fucked their minds out, loud, wet slapping sounds of sexual bliss filling up the alleyway for gods-knew how long. They became lost in each other, as they often did, time becoming a blurred mess that mattered not to them, focusing only on the pleasure in their loins and the pleasure of their partner.
That was until a loud cough, a clearing of a throat made to get their attention, sounded from behind them.
Their reactions were rather different. Cadance was an open mare and an exhibitionist at heart, so getting caught with a cock fifteen inches deep in her was on the same level of embarrassing as somebody watching her tie her shoelaces. But for poor little Dusk, this situation was paramount to the worst thing he could ever imagine. Here he was, Crown Prince of Equestria, caught in an alley with his cock in his sister-in-law, her fingers up his ass, coated in his own cum, and lost in cardinal bliss.
"Gleaming!" Cadance exclaimed in a happy fashion, eyes closed and smile wide at the sight of her wife.
Oh no.
"I thought you guys said you were gonna wait for me at the train station?" Gleaming Shield's usual rough tone asked from behind Dusk.
Nonononononono.
"That was the plan, but Mr 'Gets an erection when the wind blows' decided he wasn't stallion enough to dick me down in front of an audience, so he decided to slink off here to get his rocks off," Cadance said with a shrug.
"I was wondering why I could sense the both of you down here when I had a look," Gleaming shrugged, placing a hand on the shoulder of her younger brother and yanking him literally out of her wife.
Dusk was turned around and faced with his older sister. His cock was still stiff, dripping with the lady-lube of Cadance's cunt and his own pre, he was soaked from the chest down in a mix of cum and sweat, and couldn't have pulled his pants up if he tried due to the fact he shredded them. His eyes locked onto Gleam, the burning blue of her soldier's expression settled nicely with the wide, arrogant grin she had on her face.
"Hiya, Twink," she said with a playful growl in her voice. "Enjoying yourself?"
"I... I'm... uh..." he stammered, his dick twitching in regretful arousal as Gleam stared down at it for a moment.
"Oh... fuck," she purred, putting space between the two of them to admire his length for a while longer. "When did it get that fucking big?"
"G-Gleam!" Dusk stammered, his cheeks red as a tomato at his sister's brazen, incestuous flirtation.
The larger mare, standing over a foot taller than himself, looked down at him, noticing a small smear of white on his jaw, cocking her head playfully as she pointed at it.
"You gotta little... just a bit of..." she said, shrugging her shoulders after a moment with a sigh. "Don't worry, I'll get it."
She dragged her large, wet tongue over her brother's jaw, not stopping once she'd lapped up his load, but instead locking lips with him and pushing her tongue into his mouth, sharing the sauce with a quiet giggle as she pulled him into a passionate, aroused kiss.
Dusk's brain nearly melted out of his ears at this. Questions, emotions, hormones, and all kinds of other things rocketed through his body, confusion battling arousal, arousal battling disgust. His brain was a fried mess, and seemed to be in no shape to fix itself at any point, even as Gleaming backed away and looked down at him.
"So..." Cadance asked, traipsing over to her wife and wrapping an arm around her waist, both of them staring down at the stunned Alicorn in the same way a cheetah glares at it's prey. "What are we gonna do with him?"
"I don't know about you," Gleaming grinned, licking her lips in a hungry fashion. "But I'm gonna fuck him dry."
"Such a pretty little mare, aren't you?" Gleaming asked with a grin, burying her face in Dusk's thick ass as she pinned him to the bed.
His head rocketed up, mouth open and tongue lolling out of his maw as his sister's thick, strong tongue ran over his asshole. His tail was grabbed and pinned over his back, Gleam's enormous form hanging off the side of the bed as she toyed with his ass. Her tongue found its point, jabbing at his tight, femboy asshole with a snigger of enjoyment. Her hands moved up his thick thighs, squeezing and toying with his ass as she forcefully licked his back entrance.
"Look at you squirm, kiddo," Gleam giggled, pushing two of her large fingers down to the second knuckle into her brother's tight little asshole.
Her tongue slid downwards after this, focusing on his enormous, apple-sized balls. Spit soon slicked the smooth, warm flesh as Gleaming wrapped her lips around one of his balls, sucking it gently as her continued to pump her fingers into his back end. His toes curled up and his fists balled, biting down hard on the bed sheets as his sister's strong, rough fingers had a field day with his innards.
"Gleam... be gentle," he begged as she continued to blast his asshole, the force of impact of her rough fingering physically rocking Dusk forward as it happened.
"Nah, son, you've got a booty made for pounding," she giggled, slapping him on the ass and watching the thick, purple flesh jiggle as she did so.
Dusk yelped in pain, looking back at Gleam with a scorned expression, only for her to hike him up to his knees and bend him over again, burying her mouth in his ass once again before wrapping both hands around his shaft. Despite being a mare as strong and as rough as she was, Gleam had a surprisingly soft touch. Her soft squeezes and rapid stroking of his cock, not to mention the thorough lapping she was giving his sensitive back end was enough to send him cross-eyed.
He was dripping pre onto the bed in a matter of minutes, panting heavily as he rested on his elbows. He bit down on his bottom lips, instinctively rolling his body forwards with each lap of his sister's warm tongue, losing himself in the pleasurable pressure of her experienced maw.
It was too much for the svelte stallion to endure, gritting his teeth and feeling his eyes roll back as he came deep into the bed sheets. He soaked the snow-white linens with a torrent of his own colourless muck, pumping his hips forward into Gleaming's hands as she continued to stroke him through his orgasm.
"Holy fuck..." she chuckled in an amazed manner, watching her brother's balls ferociously twitch as they worked overtime to fill each and every drop of his semen to the brim with hyper-fertile sperm.
Once he'd finished his orgasm, Gleam wasted no time getting to the good stuff. She wrenched him over, settling him down on his back before gliding up his body and planting her fat, round ass right on his face. The scent of her pussy was mind-melting, barely able to restrain himself from cumming a second time at the scent of it alone.
"Cadance says you're pretty good at this," Gleaming smiled, looking down at him as she ran a hand through his sweat-slicked mane. "Gimme a good time, Twink."
Dusk obeyed and did so gladly. He used the flat of his tongue to spread her sweet cunt, an overwhelming taste of blueberries as delicious as they came danced along his tastebuds. He moaned as audibly as she did, feeling pre already bubbling up and out of his cock and sliding down the length of his lavender tool.
He snaked his hands over her hips, fingers digging deep into that mountainous ass, adoring the feeling of trained muscle in her glutes mixed in with her 'natural talent' that she'd clearly gotten from their mother. He felt a shiver run down Gleam's spine as his mouth made it's way to her clit. Sure, it lacked the flavour he was dying to get a taste of, but he was a professional. He had a job to complete and a quota to hit, so he wasted no time getting to the pleasure centre as fast as possible.
He heard her giggle in a way that she almost never did: effeminately. Gleam was as butch and as burly as they came, not being a dresses and frills mare, so for her to make a sound so mare-like, for her to lose herself in her gender for even the slightest moment... especially by his own actions was something that made him feel as pleased as her tongue had against his asshole. His sucked her clit gently, feeling Gleam's impressive weight shift as she began grinding her cunt against his maw.
She was panting now, tongue lolling out of her mouth as a heavy-blush made itself at home on her cheeks. Her hands went from slicking and pulling his mane to a much gentler motion, stroking him in an attempt to soothe. Dusk gently gripped her thighs, pulling her further down for a harder licking. He could feel the shivers bolt up and down her body as he hit sweet and sweeter spots, stealing moans from the dominant mare as he continued to kiss, lick, and suck his way closer and closer to her orgasm.
She swivelled her hips, grinding in a circular motion against his mouth, the adorable mewls she was letting out making Dusk's cock ache with a burning desire to be inside her. It seemed that Gleam and himself were on the same level at this point, as she quickly and suddenly removed herself from his mouth, sitting down on her haunches and looking at him.
"C'mere," she beckoned in a soft manner, holding her arms out gesturing for him to come towards her.
He did as told, getting onto his hands and knees to crawl over to her. She met him halfway, leaning down on her arms and kissing him as she'd done back in the alleyway. Her hand once again made it to the back of his head, toying with his long, girlish ponytail as her tongue snaked back into his mouth. She used her larger size and superior strength to position him the way she wanted.
He was resting on his knees with his legs spread good and wide, allowing Gleam perfect access to his cock for whatever plans she had for it. She then soon straddled his waist, squeezing his cock between his soft, flat stomach and her hard, chiselled abdomen as they continued to kiss.
"I still can't get over how big you are," she chuckled in a soft, loving manner. "If I'd have known... I'd have done this with you earlier."
"So... back in the alley," Dusk said, sucking her neck gently inbetween words. "Was that spur of the moment?"
She hesitated for a long moment, eyes unfocused and looking past her brother, merely placing a hand on his large ass and squeezing gently. Dusk's eyes fluttered, gently grinding his cock against his sister's rock hard stomach while jutting his backside out to really let her get a grip on his voluptuous curves. Fear bit into him for a moment when Gleam didn't answer, but she soon soothed his worries.
"No. I say your size swayed me, but..." she said, straightening her back and pressing Dusk's face into her enormous breasts. "I wanted to do this for so long. I just kept it a secret because I was scared."
"Scared?" Dusk joked. "You?"
"Heh," she said with a snigger, now using both hands to massage her brother's ass. "Seriously... I've come so close to telling you how I've felt for years now. Heart always felt like it was gonna burst, though. Could barely get the words out without feeling like I wanted to vomit. I wanted a piece of you, more than any mare should ever want a stallion, but I could never say it."
"What changed?" he asked.
"I got too horny to think straight watching you in the alley," she answered almost instantly, a small smile on the corner of her lips. "Was like watching an animal. So visceral, on such a base level. You'd really lost yourself to your lust and... and it was fucking hot. With how I'd felt, I was always on the edge of losing myself... but that was all I needed to push me over. I want you to rut me like that. I want..."
She fell silent, eyes falling away from his once again as her words caught in her throat. Dusk looked up at her, head cocked and confusion plastered on his soft features.
"Gleam?" he asked, eyebrow raised.
"I..." she said, bunching her cheeks up before sighing loudly, clearly throwing caution to the wind and confessing. "I want your baby."
Shock shot through him instantly, then confusion, then arousal, then disgust, and finally back to shock. His eyes were wide and his face was nothing more than a signal of confusion that someone could probably see from space. He thought for a brief moment, thinking back to how Cadance had said it to him months ago, mentally scanning over every word his sister had just said to him, and finally thinking about the sensations he felt when looking at the baby bump Cadance was beginning to get.
"Okay, Gleam," Dusk nodded, smiling widely at his older sibling.
"R-Really?" she asked in surprise, her hand going to her lip in a shocked gesture. "I thought for sure you'd be... I don't know, scared, or freaked out or something."
"Hey, now," Dusk shrugged. "I'm quite the freak myself."
"Yeah?"
"Yeah. Want me to show you?"
"Until the end of time," Gleam said, wrapping her arms around his neck and kissing him as he lay her down on the bed.
Dusk positioned himself at her entrance, heart thundering in his chest as he looked down at his older sister. For one of the first times in his life, he could see something he rarely ever did. Her mane wasn't tied back in her usual soldier bun, her body wasn't covered in stallion's clothing, and she wasn't wearing a smug expression or some other kind of macho posture.
She was nude before him, even with all the muscle, baring her enormous breasts, showing off her wide, motherly hips, and her cute little pussy. Her mane was long and splayed across the bed, two-tone blue locks radiating a beautiful form of femininity. And her face... she was blushing, hard and true. Cheeks as red as a tomato, not resembling the boisterous badass she usually came across as.
She was exposed, vulnerable...
Beautiful.
He pushed inside her, gritting his teeth at the sudden tightness clamping down around his cock.
"Fuck, you're tight," he moaned, eyes screwed shut as a quiet groan of pleasure came from Gleaming.
"I... I don't fuck stallions all that often," she whimpered, her masculine growl gone entirely from her voice. "I don't... I'm not a huge fan of..."
Dusk leaned down, burying himself in her chest as he got into his rut, the tightness of his sister's near-virgin cunt almost taking his breath away. He kissed her collarbone, feeling her hands running through his mane once again as he got to rutting her. Her voice was higher-pitched than normal, mewling and moaning in a way he'd never heard from her before. He lapped the sweat from between her breasts, kissing one of her nipples before running his tongue along her areola.
She was almost too tight to pick up the pace with, the resistance and grip of her gorgeous little pussy against his monster cock made it nearly impossible to move properly. She kissed the top of his head, her soft, wet lips leaving a stain of blue on his forehead, marking him as hers, even if for one night only. He could feel his cock bulging through her stomach, the heat of his length radiating through her, even with all that muscle on the big mare, he could still feel his warmth.
There'd be another kind of warmth in her soon enough, one that would make it's home in her womb for the next eleven months before lighting up all their lives. Cadance would be due before Gleam was, so there'd be a three month period before the second one arrived, but it didn't matter. He'd care for them both and love them both just as much. His own little progeny to bounce on his knee, to tell stories to, to spend time with, and to show just how much he loved them both.
Gleam moaned loudly as Dusk managed to get it going inside her, hips striking against hers with a dull, fleshy thud. The bed knocked against the wall loudly, sweat clung to both of their bodies as a testament to their exertion. Gleam wrapped her legs around his waist, her muscular thighs clinging to his wide hips and locking him in place; as if he'd ever dream of going somewhere else.
His attention was stolen by a third presence in the bedroom. Cadance had made her way over to the bed, using magic to disrobe herself and lying down next to her wife. She didn't say anything to Gleam, and neither did Gleam speak to her. She merely snuggled up alongside the larger white mare, watching intently at Dusk's cock burying itself inside her over and over again. She took hold of Gleam's hand after a moment, gliding it down to her stomach, allowing her to feel the baby bump on her own belly as a kind of clairvoyant act, eager to show Gleaming what she would gain from this venture.
This had gone from an unholy tryst between siblings; a raunchy, sinful romp through sexual bliss. But it had become something more. A wife had joined in, the moaning and dirty talk had died out entirely. There was no desire for sexual pleasure, no elation gained from incestuous acts, nor any egos to be boosted or prodded from sexual prowess.
This had become a wholesome conception ritual. That was all it was, and yet, everything it needed to be. Dusk lay with his sisters, one womb already filled with their happiness, and he was eager to make it a second. He closed his eyes, focusing entirely on the scent of his older sister, the noises she made as he rutted her soft, tight cave. He groaned quietly, feeling a hand, Cadance's smaller fingers, pressed against his chest. Cadance was the princess of love, an icon of fertility throughout all of Equestria. There was no better being in existence to watch over such a perfect conception as her.
And the conception soon came. Dusk whinnied loudly, breaking his dam and ejaculating deep inside his sister. If the force of his pounding wasn't enough to make her cum, than the flow of his orgasm did it in a heartbeat. She moaned as loud as she'd ever done, uninhibited by fears of being heard or discovered. Her toes curled, fingers dug into the bed sheets, and bit down on her bottom lip almost hard enough to draw blood as her brother impregnated her. It was almost as if the two of them could feel it, the surge of sperm rushing through her insides, the lucky one finding it's way home and creating a being that would make their lives even more perfect than they could ever imagine.
He straightened himself up, opening his eyes and looking at his sister's belly stretch and expand, swelling and filling up to the brim with his hot, thick cum as it fertilised her. Cadance's hand rested on Gleam's stomach, feeling the cum slosh and gurgle around inside her as Dusk continued to inflate her. She reached her peak, looking as if she were ready to give birth to their child at any moment, before he pulled out. She spurted like a fire hydrant, cum jetting from her innards with a great amount of force. The heavenly bulge in her belly began to shrink as she emptied herself, staining the bed sheets and floor around them with Dusk's mighty load.
They didn't care, though. Nothing else mattered to the three of them as Dusk snuggled up against his sisters, a wash of exhaustion rushing over both himself and Gleaming Shield as they snuggled against Cadance's buxom form, the fertility goddess smiling at both of them as their eyes slowly closed, a single sentence being said between the three of them before sleep took them from the world of consciousness:
"I love you more than anything else in this world."
