Cadance’s eyes slowly fluttered open, a ray of sunlight shining through the window to illuminate the pile of peaceful ponies she was a part of in the middle of the bed. She wearily picked herself up, surveying the room as she rubbed her eyes and stretched out her stiff muscles. She found herself with a wing stuck underneath the slumbering form of Rarity, the fashionista lying on her side and hugging the Princess’s soft feathers as she slept without a care in the world. Cadance carefully worked herself from underneath the unicorn, replacing the cushiony appendage with a pillow that had been discarded onto the floor. Rarity mumbled something incoherent as her fluffy cushion was pulled away, but, other than that, gratefully accepted the new, unliving one as she continued getting her beauty sleep.

Cadance glanced down and realized that the white mare was acting as a pillow herself; the poofy pink mane of the party mare known as Pinkie Pie obscured her diamond cutiemark as she used her friend’s flank to prop the back of her head up. The hyperactive mare stayed surprisingly silent and still in slumber, the sight of a Pinkie not in motion a rare one in Equestria. Laying on her back had left her belly wide open for snuggles, and Cadance grinned at the peaceful smile on Fluttershy’s face as the pegasus nuzzled against the soft fur of Pinkie’s stomach. Peering over the edge of the bed revealed Applejack and Rainbow Dash, the two mares apparently unable to settle their ‘differences’ as they slept head to crotch with each other. Both ponies’ rears were a mess of matted fur and wet streaks, suggesting a night full of ‘arguments’ even after Cadance had fallen asleep.

Slowly the Alicorn crawled towards the edge of the bed, carefully making her way up and over the slumbering ponies so as to not wake them. Judging by the position of the sun outside of the window it was still rather early, and the Princess of Love and no intention of ruining the serene scene of slumbering mares. Cadance smirked to herself. ‘After last night, they’ll need all the rest they can get.’

Just before she reached the edge of the bed she paused.

‘What am I forgetting?’

She lowered her head, a large white stain on the sheets greeting her as she remembered what had happened just before she had fallen asleep...

Twilight couldn’t find an opening in the assault to catch her breath. Not that she would ever want the euphoric ride she was on to come to an end, so she simply continued moaning out the stallion beneath her’s name as he battered her gates with earth shattering thrusts.

“Oh Shiny... “

Her eyes rolled into the back of her head as the sound of her voice made the thick rod of flesh within her throb, stretching her out so satisfyingly that she wondered how she hadn’t tried this before.

“Mmm... Twily…”

She gasped once more, her pummeled pussy clenching around the assaulting invader burrowing into her depths as she groaned from hearing his voice. The deep, gasping tones of a stallion breeding a willing mare. Lifting her hips up as he pulled away gave her the leverage to slam her hips back down as he came up, almost the entirety of his shaft allowed to escape her leaking confines before forcefully filling her once more. The satisfying slap of white hips impacting purple rear echoed in her mind as she continued pounding herself into her brother’s lap, her third orgasm of the night quickly building to a crescendo.

She smiled down at her brother as she felt his balls pull up in her magic, trying to get as close to the stallion as possible to deliver their creamy payload inside of a mare prepared for it. And Twilight was more than ready to accept whatever Shining had in store for her, just the thought of her brother emptying himself deep inside of her almost enough to push her to the brink. But she held on, trying as hard as she could to delay the inevitable until both she and Shining could climax as one.

“Twily… I’m close…”

“Me too…” She rolled his balls around in her magic and leaned down towards his face, her nose tapping his with their lips just a hair’s width away from each other. Breathily, she whispered, “Fill me up, Shiny… Fill up you little sister…”

Shining’s eyes clenched and face contorted in a scowl as Twilight’s eyes opened wide and mouth opened in a scream. The first blast of heavy stallion spunk blasting against her inner walls was enough to tip her over the edge, uncontrollable spasms wracking her body that clenched her silken tunnel around Shining’s throbbing shaft. More and more of his warm sperm flooded her insides, the mind-numbingly pleasureable flare wide enough that it blocked any of her brother’s essence from escaping. Each spasm through his body caused his balls to clench, emptying themselves of their creamy contents directly into his sister.

Shining grabbed her face with both of his hooves and forcefully shoved his lips onto hers, digging his way into her mouth to silence his deep moans. It felt as though he was gushing out gallons of stallion spunk from his shaft, the rhythmic constrictions of Twilight’s velvet passageway milking him for everything he had. It was all perfect; the tight marehood constricting around his throbbing cock, the stream of marecum covering his thighs and balls in warmth and, as he opened his eyes to look at Twilight, the beautiful face of a mare in complete and total bliss as she climaxed along with him.

Only when the spasms slowed did the siblings separate, a line of saliva connecting the pair before breaking off as Twilight opened her eyes. They stayed half lidded, weighed down from post-orgasmic bliss as she looked down at her brother. No words were shared between the two, Twilight unable to find the words to express the new-found feelings that wracked her nerves. Instead, she leaned down and kissed him on the lips before cuddling up against his chest, laying the top of her head in the curve of his neck.

She halted him as he made a move to withdraw, gasping from the feeling of his seed sloshing around within her lightly spasming depths. “Wait. Let’s stay like this for a little while longer…”

Shining placed a hoof on her back, calmingly rubbing her as he kissed the top of her head. “Okay, Twily…”

‘Hmm… I wonder where those two went…’

Gingerly the pink Alicorn stepped off of the bed, stretching her legs out as she checked the room for further clues. She kept her hind legs straight as she slid her forehooves forward across the floor, groaning as she stretched out her body. With a smirk she flicked up her tail, just in case anypony on the bed happened to be peeking at her as they ‘slept’. Looking back at the pile of mares offered no response, but did reveal another wet spot; this time, it was on the side of the bed...

“Mmm… getting brighter outside…”

Twilight lifted her head from her brother’s chest, turning her head to look out the window. The darkness of the night sky had brightened into a dull grey, Celestia’s sun waiting just underneath the horizon for the solar Princess to lift and begin a new day. She snuggled up against Shining one more time, rubbing her cheek against the soft white fur of his chiseled chest before sitting up in his lap. Her brother had been slowly rocking his hips as she rested, swirling his half-flaccid stallionhood around inside her warm confines to keep himself hard enough to stay inside her. She pressed herself into his groin, feeling her rear end press back into his pillowy balls one final time before starting to stand. Each inch of shaft that grinded against the folds of her marehood brought with it a wave of pleasure, the girthy shaft digging its way through her inner folds in an attempt to escape to the outside world.

Twilight stood up on her hind hooves, front end still bent over with her hooves on her brother's sturdy shoulders. Twilight took a peek between her forelegs, looking between the twin mounds of her teats to watch the stretched pair of purple lips wrapped around the head of her brother’s shaft. Only his flare connected him to her, the blood filled cork the only thing holding back the seed she could still feel flowing around her inner sanctum. With one last look at her brother, and one final peck on the lips, she watched in full detail as she raised her hips up one final time.

Her labia slightly distended from her body as the flare inside her tunnel tugged her plump lips in one final attempt to stay within its new-found home. Soon the pressure became too much, her lips slowly parting around the black member coming out of her. With a loud pop and a gasp from both siblings the head finally swung free, falling down to lay against the stallion’s white thigh as even whiter stallion cream began leaking from her abused lips. The feeling of sudden emptiness became too much for the mare, legs wobbling enough to force her to fall onto her back at her brother's side with a groan.

"Sweet Celestia..."

Shining turned over to his sister, bringing a hoof up to nudge a piece of her mane away from her face. “So… heck of a way to celebrate the holiday, huh?”

Twilight chuckled, playfully hitting him in the shoulder with her hoof. She weakly picked herself up, hooves shaking from exhaustion as she gradually made her way off of the bed. She turned to look back at her brother as he scooched his way down the bed, hind hooves hanging off the edge as he sat up and cracked his back.

“Ah… Needed that… Feel like I’ve been laying down for weeks…”

Twilight’s eyes slowly drifted down his body, locking in on the black flesh between his legs that hung over the side of the bed. Wet streaks of white covered the shrinking shaft, his balls and thighs particularly coated in a mixture of their combined sexual fluids. Shining had closed his eyes as he rolled his head around, more cracks popping from his neck as he worked his stiff muscles, giving Twilight a perfect opportunity to sneak up on him...

Shining gave a startled jump when something warm pressed against the sensitive head of his shaft. Looking down revealed Twilight sitting on the ground right in front of him, lifting up his flaccid cock with the tip of her tongue as she sensually stared at him. Slowly she dragged the wet appendage up the face of his flare, his member eventually flopping down to rest against his sack as she finished her lick.

“Wh… What are you doing?”

She gave him another lick, this time pressing the thick stallionhood against his balls as she slurped up the salty mixture of their combined orgasms. She made a show of licking her lips as she finished, still staring him right in the eyes. “Just cleaning you up…”

She didn’t wait for his reply, diving underneath him to pop one of his musky balls into her mouth. She moaned around the thick orb, licking the leathery flesh surrounding the warm foal-maker to wipe away the white streaks covering his black scrotum. His cock laid against her forehead, resting on her soft mane as she gobbled up the meaty fruits hanging between his legs. Once the taste of cum faded away to the taste of warm flesh, she switched to the other ovid stone to clean it as well. Shining leaned back, relaxing on the bed to enjoy the special treatment his sister was giving him below the waist.

With some adjustments she was able to squeeze each of the plump stallion nuts into her mouth, lips closing around behind the twin orbs as she cradled them with her tongue. She gave them a soft tug, pulling the testicles away from their owner’s body until they fell out of her mouth and swung back to settle against the edge of the bed. She dove in once again, this time attacking the skin connecting balls to shaft with soft nibbles before dragging her tongue up the underside of his member. The entire length rubbed against her face as she made her way to the top, matting her fur with streaks of white and filling her senses with the scent of a male.

Without hesitation she wrapped her lips around the head of his stallionhood, moaning around the thick flesh that filled her mouth with a barrage of musky flavors. She brought her forehooves up and lifted his testilces, each meaty sperm silo enough to fill her hoof as she tested their weight. She groaned as the cock in her mouth began to expand, filling with blood and extending deeper into her maw as her brother became erect once more. In fact, she was moaning a whole lot…

“Shit AJ! Right there... Common, eat that pussy...”

Twilight paused her brotherly fellatio, pulling away from Shining’s lap to turn and look at the corner of the room. Applejack and Rainbow were laying on top of each other, each mare face-to-crotch with the other as they writhed with bliss on the floor. From her position by the bed, Twilight could see between the legs of the pegasus as Applejack went to town on Rainbow’s plump cerulean lips. Flashes of pink drew Twilight's gaze as the earth pony dug her tongue into her moaning friend, her slimy appendage thick enough to split Rainbow apart to reveal her moist depths to the world.

Twilight turned as she heard something else behind her. Cadance and the rest of her friends were sprawled out across the floor, a heap of multicolored mares snoozing away their post-climax exhaustion. She turned back to her brother, a sheepish smile on her face as she kissed the tip of his cock.

“Let’s take this somewhere more… private.”

Cadance made one last check around the room before starting to make her way to the door to see if Twilight and Shining had already gotten up. Just as her magic reached out towards the handle, she stepped on a wet spot on the carpet. Lifting her hoof and looking down, she could see a damp circle just before the door…

Twilight carefully levitated Fluttershy onto the bed, the last of her slumbering friends snuggling up against Pinkie Pie’s soft belly as she was placed amongst the rest of the mares. She left Applejack and Rainbow alone in the corner, neither mare paying mind to the purple Alicorn as they dug into each other’s crotches.

Shining had climbed from the bed, stretching out his weary muscles with his fully erect pride still standing between his legs. Twilight had been teasing him the entire time he waited, brushing his face with her tail as she passed and giving him an unobstructed view between her legs as she moved her friends from the hard floor to the much more comfortable surface of the bed. Drips of thick white cream still dripped from her lips as she walked about, creating a trail behind her. Twilight smirked as she felt her brother’s gaze glued to her rump, making sure to put a little extra sway to each of her steps to give him plenty of eye candy.

Finished, Twilight seductively made her way towards the door, half-lidded eyes staring back at her brother with her tail fully flagged behind her as she strutted. A smile broke across her face as she watched him trace her movements with his eyes, the half-deflated stallionhood between his legs starting to once again engorge with blood after being neglected for so long. “Alright, let's go… wouldn’t want to wake them up now, do we?”

Just as her magic reached for the door handle, a large mass tackled her into the hard surface before surging up her back and mounting her. Twilight’s face was mashed into the door, her horn scratching a gouge into its surface as it sparked from the sudden onslaught of pleasure radiating from her rear. Her tongue lolled out of her mouth as Shining shoved his shaft once more into her depths. She gasped as he went balls-deep in one smooth thrust, biting onto her hoof to muffle her pleasured screams as she was roughly pummeled against the door.

“Sh-Shining!? What if- ohhh…”

Shining bit down onto the scruff of her neck, hot breath washing over the back of her mane as he snorted. “If they wake, let them watch…” came his muffled growl of a reply, following the statement up with another full body thrust into the quivering mare beneath him.

Twilight spread her hind legs apart to give him more room, reaching down to her crotch to rub at her furiously winking clit. Every so often he would buck into her hard enough that his balls would swing forward like a wrecking ball and tap her hoof, at least until she wrapped them in her magic and began to massage the two heavy stones.

“Alright, just make it quick…”

Shining grinned around her neck, releasing his hold to bring his mouth to her ear. “Oh, trust me, Twily. I can make it quick…”

His entire body flexed as he heaved himself forward, the thunderclap of flesh impacting flesh ringing in each of the siblings' ears. Twilight had to bring her rubbing hoof from between her legs back in front of her to prevent herself from slamming face-first into the door, the forceful jab into her rear slamming into her with enough force to propel her up onto her hind hooves. Shining followed her, each of the siblings standing upright with their fore hooves holding them up on the door. Shining continued impaling her with full-length thrusts, pulling out far enough that just the tip sat among the warmth of her snug folds before sinking balls-deep back inside with one smooth motion. Twilight’s face grinded against the hard surface of the door with each of her brother's swings, tongue lolling out of her mouth as Shining ravaged her with all of his might.

A sudden warmth surrounded Twilight's sensitive horn, the mare looking up to see her brother as he bent down and engulfed it into his maw. He began swirling his tongue around the spiral bone from base to tip, and Twilight found her worries about making too much noise utterly unfounded; she could not find it within herself to even mutter a squeak. What she did find was her brother was not lying; already the tingling of yet another orgasm was building inside of her, waiting for her to burst into climax.

Air rushed into her lungs as an unexpected bolt of pleasure struck her in a head-on collision. Shining had wrapped his magic around her clit and was massaging the bundle of nerves even as he drove himself in and out of her slick tunnel. Her hooves began to spasm, unable to find anything to hold onto as the influx of pleasure became too much for her brain to handle. Like watching a lit fuse she could feel an imminent explosion of ecstasy coming, all the muscles in her body clenching in preparation for the coming surge of climax.

One last powerful thrust mixed with a twist to her clit and a drag of tongue up her horn was enough to finish her off, the feeling of a bolt of lightning coursing through her body signaling the start of an oncoming storm. Her hind legs gave out, her brother the only thing holding her up against the door as he continued to excavate the spasming tunnel of her marehood. Marecum oozed down to the floor between his legs, splashes of his sister's feminine nectar splattering onto his swinging ballsack before falling to soak the carpet below.

Just as she came down from her high he entered his, bringing her right back into the land of euphoria with a single blast of warmth into her depths. Even after everything else that had transpired that night his load was still a full one, heavy shots of cream that painted her already used insides with a fresh coating of white. This time he did not pause inside of her, pulling out just as he finished filling her with his seed. His wet cock flopped out of her with a wet *schlorp*, releasing a splash of gooey stallion semen from her gaping lips that joined the wet spot on the floor.

He dismounted her, the mare’s body still spasming as she slid down the door to the carpeted floor. Her eyes were still rolled up into the back of her head, body giving slight twitched as her brain attempted to make sense of what had happened. Shining picked her up in his magic, opening the door and taking her with him as he stepped through.

“How was that for a ‘quickie’?”

Cadance rubbed her hoof on the gouge in the center of the door.

‘Hmm…’

Walking out into the hallway, she looked both ways for any kind of signs about the pair's whereabouts. In the end, an urge to go to the bathroom made her decision for her as she made her way down the hall. Opening the door revealed a grand master bathroom, the tile floor a perfect match for the toilet in the corner and the humongous shower at the opposite end of the room. Each step closer she got, an off-white streak could be seen clearer and clearer on the wall of the shower…

“Sweet Celestia Twily, that was amazing!”

Slowly he lowered her onto the ground, the mare standing on shaking hooves for a moment before finding her hoofing. The purple mare batted his face with her tail as she walked by, the offending appendage lifted up high to show off the white mess between her legs. His latest load slowly dribbled from her thick folds, white streaks of stallion sauce coating her swaying purple behind. She sauntered over to the shower, keeping her tail up high as she bent over to mess with the dials. Shining made a move to mount her, but her magic held him at bay as the shower slowly heated up.

“Uh uh uh, Shiny. We need to clean ourselves up for tomorrow.” She stood up and turned back towards him, shrugging. “Well, ‘for today’ I guess… Still can’t believe we did… THAT all night… one heck of a Hearth’s Warming story though, huh? Not that you'll be telling anypony about this, got that?”

Twilight stepped into the shower, the water cascading down her body and plastering her mane to her face. Shining entered behind her as she lathered up, reaching for some soap before it was pulled away from him in his sister’s purple magic. Turning to look at her, he saw the mischievous grin on her face before he felt her magic down between his legs. Before he could say anything, she crawled underneath him and popped the head of his hardening cock into her mouth. Shining sighed out, the mixture of warm water running over his back, the tingly sensation of her magic working the base of his shaft and his balls, and the tongue cleaning off the tip of his flare sending a mind-blowing mix of pleasure into his brain.

He reared up and placed his forehooves on her back, warm water running down his rear and dripping off his balls as he slowly rocked his hips into her face. “So much for getting clean…”

Twilight slowly pushed herself further down Shining’s lengthy pride, moaning as the warm rod of flesh worked its way into her throat. She found it easier to handle the second time around, experience and the position she was in underneath her brother making the passage a smooth one as she passed his medial ring. She could feel her throat bulging out as she swallowed around her brother’s thick cock, moaning from the sensation and from the delectable flavors coating his flesh.

Shining grabbed a bottle of shampoo and applied it to Twilight’s lower back, squirting out a decent amount of lavender scented soap onto her coat. Slowly he massaged her back, working the stiff muscles as she worked his own stiff muscle between his legs. Grasping her rear got a gasp from the mare, a warm wave of air coming from her nose to brush across his balls. Slowly he kneaded her cheeks, teasingly slipping a hoof into the crevice between the twin mounds of soft flesh to brush across her marehood. He moved his hooves away before she could get too worked up, however, to clean the fine hairs of her tail. Many of the purple strands were encrusted in white, fluids from their earlier activities that had dried up and made a mess of her rear end making it tough to clean.

He continued to balance himself with his forehooves even as he used them to bathe Twilight, working back up the curve of her rump to start ascending up her back. Gradually he stood up straighter and straighter, hooves going from the small of her back to her wings as he scrubbed her down. He took a moment to really work the sensitive muscles betwixt her feathery appendages, smiling as he got a moan that vibrated around his cock in response. He had a final destination in mind, however, so rather quickly he moved on to work the area between her shoulders.

By then Shining was standing almost completely straight up on his hind legs, almost in a perfect breeding position if not for the fact that Twilight was facing the wrong way. Not that he minded; her mouth felt amazing wrapped around his member and her throat was as tight as any marehood he had ever known. His gently thrusting hips began to pick up speed, weak taps to the tip of his sister’s nose with his balls progressively becoming stronger. Within moments he was treating her face to a rough round of face fucking, his hips almost pulling his shaft completely from her maw before burying itself back down her throat.

Twilight closed her eyes and moaned, letting her brother use her mouth any way the stallion saw fit. The warm humidity from the shower put her in a daze, her world reduced to the confines between his white thighs that surrounded each side of her head. The sounds of the water sprinkling down around her was not enough to drown out her brother’s groans, a sound that had become the finest music to the mare over the past several hours.

And then she felt the cock in her throat bulge once, twice, three times before a pleasing warmth shot directly down her throat into her stomach...

Cadance had no idea where to look after exiting the bathroom, so she decided that she might as well wander the Castle of Friendship for a while. She hadn’t really had the chance to check the place out while running her own Empire, and the magical structure reminded her a lot about the architecture back home. As she wondered if the Crystal Empire and the Castle of Friendship were somehow connected, the smell of something burnt crossed her nose. Following the scent, she found herself in a large kitchen towards the center of the Castle. Everything here looked for the most part untouched, Cadance laughing to herself as she thought about her sister-in-law trying to cook anything with all the large appliances that surrounded her.

She eventually reached the source of the smell, a small toaster on the counter slowly smoking with a pure-black piece of bread still inside. On the counter next to the toaster, silverware and plates had seemingly been haphazardly pushed aside in haste. Cadance even had to watch her hoofsteps as a plate had fallen and broken on the floor…

“Crap, Shiny! It’s already almost morning! We gotta stop and get ready for Hearth’s Warming!”

Twilight untangled herself from her brother, picking herself up off the cold tiled floor of the kitchen to make her way over to the coffee-maker. She swiftly set up a pot to brew before bringing a loaf of bread from the cabinet over to her with her magic. “Toast fine? I’m still not used to all this new stuff here.”

Shining plopped onto a seat at the kitchen table, sighing out and leaning back in his seat. “Yeah, toasts fine.” He grinned at his sister, Twilight not noticing the glint in his eyes as he spoke. “I could use something to drink, though. I’m parched!”

Without turning around, Twilight opened up the loaf of bread and placed two pieces inside of the toaster. “Well, coffee will be ready in a couple minutes. Do you want some water or something? Just grab some out of the fridge over there.” Just as she hit the lever to start making the toast, she was lifted up into the air by magic and roughly plopped down on her back on top of the counter. Plates and silverware were pushed aside by her body, one plate falling off the edge of the counter before crashing onto the ground below and shattering into pieces.

“Shining! What the- “

She never got to finish scolding him as he pulled her hind legs apart and shoved his muzzle into her plump folds. She gasped, leaning her head back onto the cold surface of the counter as she spread herself apart even more for Shining as he sated his thirst. Her thick labial lips were no match for the hungry stallion, nibbles along the edges leading to succulent folds of flesh being sucked into the stallion’s mouth. As soon as he had cleaned out her tunnel of her sweet nectar he moved up and suckled on the bulb of her clit, looking to replenish the stockpile of the slightly grape-flavored drink.

The lashes to her button of pleasure quickly had the desired effect. A scream that devolved into a moan was all the sign the stallion needed to move back down, fresh rivulets of marecum streaming out of her quivering marehood for him to sample. Once more he slobbered over his sister’s cunt, slurping up her sweet ambrosia as if it was the only oasis in a never-ending desert. He shoved his muzzle against her opening, hard enough that the tip of his nose entered her slick passage and filled his senses with the scent of a needy mare.

Twilight writhed on the counter, silverware clinking around and falling to the floor as her legs spasmed from pleasure. Her brother’s tongue just kept going deeper and deeper into her depths, finding new pockets of mare juice to devour before pushing further. He had no rhyme or reason to his methods, no pattern that she could settle into to calm herself down. Her breaths came in short gasps, her voice growing higher in pitch with each moan that escaped her lips.

Shining pulled away just before she reached the pinnacle of pleasure, lazily licking the leaking labial lips to calm her down and pull her from the edge of orgasm. He moved up past her clit to find the small bumps of her breasts, latching onto a nipple and viciously lashing it with his tongue. He softly grasped the perked stub between his lips and gave it a tug, a bolt of pleasure racing up Twilight’s spine as her brother masterfully worked her over.

She lowered a hoof to his head, weakly pushing him down in the hopes of maneuvering him to where he was most needed. He simply gazed at her with heated eyes and a smirk on his face as he switched teats, suckling on her other nipple as the first gleamed in the light of the rising sun that shone through the kitchen window.

“Shiny...”

With one last pull he moved back down to her weeping lips, smiling up at his sister as he paused above her honeypot. Waves of warmth washed over her privates as he waited, waiting for what Twilight did not know. The heated blush across her face and heavy pants coming from her mouth betrayed her lust as she begged him with her eyes to finish her off.

“Please…”

Shining’s hooves suddenly shot up and split her legs as far as they could go, stretching her thighs apart and leaving her marehood completely undefended from the approaching assault. The stallion opened his mouth wide, lowering his head and engulfing the entirety of her twitching lips within his maw. His nose pressed into her winking clit and his chin pressed into the bulge of her anus as he dug his tongue as far inside of her hot insides as he could go. Several inches of slimy, saliva-coated muscle extended like a spear straight into her sacred passage, scraping against her spasming walls as the stallion sucked her succulent juices straight from the source. His horn lit up to massage her breasts as he ate her out, tweaking the erect stubs of her nipples and kneading the flesh of the teat itself as he worked his sister into a frenzy.

Twilight was stunned. Eyes wide and breath held in her chest as the sudden barrage of bliss battered her insides. Shining was like a viscous animal between her legs, devouring her most private of areas like a hungry beast that had not been fed for ages. There was no slow buildup, no feeling that warned her of the coming tidal wave of pleasure, just a sudden explosion of euphoria that caused her entire body to spasm in an abrupt climax.

Her hooves flailed around the counter as all the nerves in her body fired off all at once. Her hips tried to buck up into the face of the stallion wriggling his tongue around her clenching tunnel but were held fast against the cool countertop, Shining Armor's strength too much for the mare to handle. Her chest heaved, hindlegs kicking about wildly as her marehood was drained of its sweet essence, bursts of marecum never seeing the light of day as they moved from clenching tunnel to swallowing mouth. By the time Twilight began to descend from the heights of pleasure her entire body felt tired, the mare feeling as though she could pass out at any moment laying on top of the counter in an orgasm-induced coma.

Shining pulled away from his sister’s crotch, dragging his tongue one final time from her abused depths with a loud *schlurp* and licking his lips of any excess fluid. Twilight’s legs twitched as he gave a quick couple laps on her quivering lips, cleaning up the last bit of liquid bliss that leaked from her insides. Not a single drop of her orgasm was left, her entire climax swallowed by the voracious stallion to satiate his thirst. With one final kiss on her lower lips he backed away from the counter, returning to his seat at the kitchen table and sighing out.

“Ahh… refreshing…”

He wasn’t given a moment's rest before a purple mass tackled him, tipping him and the chair he was in onto the floor...

After cleaning up a little in the kitchen, Cadance restarted her search for the M.I.A. ponies. She was a little disappointed to find that there was no feasible way of extracting the toast from its steel prison, the bread so burnt that it almost seemed to have fused with the bars around it.

'Leave it to Twilight to destroy a toaster...'

She dumped the toaster in the trash as she left the kitchen and began to go door to door looking for the siblings. They weren’t in the hallway closet, not the astronomy room, nor were they in the guest bedroom. Eventually she found a room with a large table in its middle, surrounded by a circle of grand chairs emblazoned with the cutie marks of the Mane Six. Looking closer, she saw that Rainbow’s cutie mark had a large scorch mark across its face…

The door to the map room flew open, violently banging into the wall as two entwined ponies backed into the room through it. The two were standing upright on their hind hooves, connected together at the mouth as they shared a deep kiss. Neither were paying attention to where they were going, eyes closed as they wrestled each other into submission within their mouths. As soon as Twilight backed up into a chair she lost her balance, falling over with her brother landing on top of her. Still they stayed connected, and now Shining was in perfect position to rub his slowly hardening shaft against the inside of her hind leg.

Shining reached between his legs to line himself up with her puffy folds but suddenly found himself tumbling over the edge of the chair, falling onto the floor and bumping his head. He looked at his sister as he wearily rubbed the back of his head. The young Alicorn had turned over onto her belly with her hind legs hanging over the armrest of the chair, wings reaching behind her to spread her cheeks apart. He didn’t think about the offer for a moment, immediately forgetting about the bump he had taken as he reared up and mounted the prone mare.

Brother and sister moaned out in unison as he once again filled her, her tunnel so used to the familiar intruder that it felt as though it had molded to be a perfect fit around it. Hard thrusts rocked the pair on the chair, Shining’s low hanging balls swinging forward to slap against her winking clit. He looked down at the mare beneath him, her beautiful face twisted in pleasure and eyes glazed over as she panted in pleasure. Looking just above her forehead, he could see her horn bobbing up and down in time with his thrusts as if beckoning him towards it, so he complied.

Twilight lost all the air in her lungs as her horn was enveloped by a warm and wet sensation. The thousands of nerve endings usually used to give her a feel for her magic was now blasting her brain with a constant barrage of pleasure. Her eyes got wider and wider as a static charge began to build up around the bone, soon strong enough that Shining had to pull his head back. It turned out to be good timing as a bolt of magic arced out of his sister’s horn and struck the seat next to them, the magic striking the bolt of the lightning emblem on the seat next to them. Then, the tunnel wrapped around his member began to clench around him and his world descended into white bliss...

Finally, Cadance had a clue on the whereabouts of the two ponies. A clue that consisted of a white trail leading from the seat over to a large wooden door at the end of the room. The door stood slightly ajar, a warm orange light glowing from the open crack as Cadance approached. Silently nudging the door open, she took a look around the room.

It was a grand library, stacks of all kinds of books reaching up towards the ceiling on each of the walls. A table was over by the side of the room, stacks of books piled high on top of it from whatever her sister-in-law had been researching recently. The middle of the room had a large, comfy looking carpet placed in front of a grand fireplace. On top of that was where the two missing ponies were now laying. Twilight and Shining were side by side, his foreleg draped around her waist as they cuddled in slumber. Cadance couldn’t help but smile at the cute scene before her, the blues and purples of their tails entwined together as the siblings slept.

Twilight briskly trotted around the library, grabbing books and quickly perusing them before levitating them over to the chair. Every so often she would have to pause as her body locked up, moaning in place for a moment before gathering herself up and continuing her search.

"Hold up, Shining... I'm looking for it...

Her brother was relaxing in the large chair in the corner, a shimmering ring sitting in his lap and blocking the view between his thighs. A matching circle shimmered between his sister's legs, tucked up underneath her tail right in front of her marehood. It was a special teleportation ring Twilight had told him about in passing as they walked to the library, one that allowed a user to do something in one spot while they were in a completely different area. It was an easy jump for the stallion to take; why not use it for sex?

Now Twilight was on the search for another spell, one that could be used for more pleasurable activities than it was originally designed for even as her brother slowly rocked his member in and out of her passage. It was certainly a different sensation, being able to freely walk around even as his thick rod split her open. Shining couldn't complain either, the mare's movements creating new sensations around his cock as her muscles flowed around him. Plus, it wasn't very often that he got to catch up on reading the newspaper while thrusting into a warm mare at the same time.

"Hmm... says here that Celestia's thinking about holding the summer sun celebration in Appleloosa next year..." He continued to absentmindedly rock his hips into the shimmering portal in his lap even as he read, humming to himself in thought.

Twilight had to pause again as another wave of blissful contractions rocked her body, her legs spread apart to keep herself steady as she spasmed around Shining's cock. The book she had been reading had fallen to the floor in front of her, opening up to a random page on the floor. With half lidded eyes Twilight gazed down at it, taking a second to fully register what she was looking at.

"H-hey!" She took a moment to dispel the portals, Shining lowering the newspaper with a frown to look over at her. "I found it! Come over here..."

The stallion placed the paper on the stand next to the chair and made his way over to Twilight. She motioned him to lay on his back in front of her, happily compiling as he rolled around. He kept his legs spread apart, giving the mare full access to the slick rod between his thighs.

Twilight closed her eyes and concentrated, her horn starting to cast an eerie glow around the room as she began the spell. "OK, this might feel weird for a moment, but it SHOULD work... hopefully..."

Shining Armor rolled his eyes at her. "Well, THAT certainly inspires confidence..."

Her magic gently flowed down his body and surrounded the pillar of flesh sticking up towards the ceiling. Waves of static flowed across the slick surface of the veiny shaft, swirls of purple creating a cone from the tip of the member down to the base. It even wrapped around his balls, lightly tugging on the sac as the spell began picking up strength. The magic began to lose its opacity, glowing a bright enough white that Shining had to avert his eyes away from what was happening to his stallionhood. A surge of warmth flooded his system, centralized at the point between his thighs. With one last groan from his sister, and a moan from the stallion himself, the spell completed with a bang, leaving Shining stunned for a moment before glancing between his legs to see the results.

Twilight took a look too, bouncing up and clapping her hooves in glee as she saw that her spell had worked. "Success! Oh, this would make a great report on the magics of body transmogrification!"

Shining's already impressive shaft was now an awe-inspiring tower of masculinity. The spell had been a simple growth spell normally used for simpler objects, but worked perfectly for what the siblings had intended. Engorged veins ran down the surface of the enlarged member. Shining estimated he had gained several inches in length with plenty of girth to boot. Even his balls seemed to be more bloated out than before, a pair of churning fruits dangling between his legs that promised a juicy finish to what the two planned to do next...

'...'

Cadance looked between her husband's legs.

'...Are his balls bigger?...'

“Celestia… I wish we had done this sooner…”

Twilight and Shining were laying on the library carpet in front of the grand fireplace that covered them in soothing warmth. Twilight absentmindedly threw another log into the fire with her magic, stumbling slightly as another hard thrust from her brother almost broke her concentration. She sighed out from the now familiar sensation of Shining’s thickened member burying itself deep enough inside of her to kiss her cervix, a sensation she had never dreamed that she would ever feel in her life. With the fire fed, she looked between her legs to see how another fire was being tended to.

Both ponies were laying on their sides, Shining with his belly to her back. She had her top hind leg propped up with her own hoof, giving her brother enough room to thrust between her thighs. Both of his fore-hooves were wrapped around her waist, both to give him more leverage in his thrusts and to rub at her medium-sized teats. She watched as his black rod drove a wedge between her purple lips, splitting her open and revealing her bright pink insides to the world. His heavy balls appeared at the apex of his thrusts to slap at the bubbly cheeks of her rear before disappearing behind them when he pulled out. She reached down and began to rub at her winking clit with a hoof, leaning her head back as her eyes closed in bliss.

Shining had quickly found that the increased length and girth had also come with an increased sensitivity. Her moist tunnel was so deliciously warm, almost to the point of being hot as her folds snuggled around him. He could make out each and every detail of her insides whenever he paused fully sheathed inside of her, each bump and each clench shooting another shot of pleasure up his spine. He could feel his seed churning in his balls, building up for an impenitent release into the mare milking him for all he was worth. With one final full-length thrust he hilted inside of his sister for the last time, holding himself still as his member throbbed inside of her.

Her wall was broken down when the first salvo of Shining’s thick white cream blasted into her depths, her body instantly entering a state of climax from the feeling alone. She had lost count how many times she had reached the peak of pleasure that night, and now she once again pressed herself back into her brother as they finished together. She realized that it could no longer be considered night time after looking at the clock on the wall, the sun more than likely already peaking over the horizon as her brother filled her once more with seed. Luckily this far into winter her heat cycle was virtually nonexistent, so she could fully enjoy the sensation of his unnaturally large load building in her womb without worry. Of course, she would take extra precautions once they wrapped up, but for now she simply relaxed against his chest and sighed.

Once she felt her brother’s shivers calm, she reached behind her with a hoof and rubbed at his cheek. With one last kiss, her lids slowly descended over her eyes, blacking out the world around her while leaving the sensation of the warm body pressed closely to her back. Just as she felt herself drift off into slumber, she heard her brother whisper into her ear.

“Happy Hearth’s Warming, Twily.”

Cadance couldn’t help the blush across her face as she reached the slumbering pair. The tip of Shining’s sheath sat right against Twilight’s lower lips. Most of her rear end was covered in dried up white streaks, the smell leaving no question as to what they had been doing throughout the night. Still a small amount of cream leaked from her abused labia; clearly a lot already had judging by the wet spot underneath them.

Even with the lewdness of the scene, Cadance found the pair to be utterly adorable. She had known about Twilight’s deep seated feelings for her brother for a long time, and it brought a smile to her face to see that her sister-in-law had finally been able to express those feelings even if just for a night. Feeling as though the pair could use more rest, Cadance levitated a blanked from the table over and tucked the pair in as best as she could without waking them. Walking back to the kitchen and grabbing a glass of water, she heard a commotion coming from the direction of the guest rooms. With a smile, she downed the glass in one gulp and made her way back to the bedroom.

'Might as well have a little fun while those two rest...'

Author's Note

And with that, Happy Hearth's Warming!

*looks at the calendar*

I prefer to think of myself as very early instead of late...

With that, the holiday special comes to a close. Hopefully everyone enjoyed this 'little' story of mine, I certainly enjoyed writing it! My biggest problem certainly seems to be estimating the word counts of my stories; I had originally intended this to be a one-shot with around 10 to 12k words. Off by just a teeny tiny bit...

Now, back to work on Cadance and the Art of Diplomacy! If you haven't, be sure to vote on the pairing for Chapter 4 here!
