“Thanks for having us over on such short notice, Rarity. You really didn't have to go through all this trouble.” Twilight said as she took a seat next to her brother at the small circular tea table in the private fitting area of Carousel Boutique. Out of the way of the main shop floor, this room provided a more personal experience for a customer or in this case, host an impromptu fitting for Princess Twilight and Prince Shining Armor while the trio enjoyed tea, hors d'oeuvres, and some light small talk.
“Nonsense, darling! It's no trouble at all. I'm honored that both of you would ask me to make your attire for such a special occasion! Your parents 25th anniversary is nothing to take lightly and I will most certainly make sure you both look marvelous.” Rarity replied cheerfully as she carried the tea kettle, cups, and a plate of tiny sandwiches over toward the table within her blue magical aura.
After setting everything down neatly on the table, Rarity took her own seat across from the two siblings. Humming a small tune, Rarity began pouring a cup for each of them, steam wafted out of the kettle as she placed a tea bag in each cup, a special blend she had found at her favorite tea shop in Canterlot—enhanced with a little something extra by the other 'pony' taking up residence inside her body. Once finished with each pour, she sent Shining and Twilight's cups over to them, setting them down on the tabletop in front of them.
Rarity nonchalantly started pouring her own cup, but her focus was truly on the two she had just served. A small grin formed on her muzzle as she intently watched both Shining Armor and Twilight Sparkle take their first sip—if either of them had been looking at Rarity they would have noticed the shimmer in her eyes as they turned a lighter shade of blue.
Once the two of them had swallowed the tea, it was too late, their eyes began to take on the same color as Rarity's, fully glossing over into light blue. Their mouths hung open slightly, drool pooling and dribbling out on to their chins.
Rarity's grin grew larger and more malevolent. “So, Darlings, what do you think of the tea, Hmm?”
Both brother and sister sported a dopey, mindless smile, the duo nodded slowly in unison. “It's really good, Rarity. Even better than the last time,” Twilight said.
“Yeah.” Shining let out a giggle. “This stuff is good.”
“That's wonderful! I hope you two don't mind that I put a little obedience charm in both of your teas... Neither of you will be able to disobey any of my commands until it wears off. That's not a problem, is it?”
Both the charmed ponies dumbly stared at Rarity, their mouths still hung slackjawed. “Nope, of course not, Rarity. Why would I do that?” Twilight said cocking her head slightly.
Rarity snickered softly to herself and muttered, “Just like the last time.”
Shining shook his head emphatically while holding his own dumb, giddy grin. “No, I don't mind.”
“Fantastic.” Rarity said, her expression becoming more sinister, eyes narrowing. Her pristine white fur slowly began to change to a dark, dark-gray, nearly black. “Allow me to introduce myself then...” Rarity's form grew taller, her white fur she normally sported had fully converted into a dark, nearly black color that resembled the night sky, and her beautiful purple locks now had distinct white and silvery streaks flowing through her mane. “I am the Nightmare! I've taken residence inside of Sparkle's friend's subconscious... I've been fucking your sister every chance I get. Like the proper cocksleeve she is.”
“That's cool,” Shining Armor said. His half-smile and air-headed gaze still locked on to Nightmare Rarity.
Nightmare Rarity cackled. “This is simply too perfect... Do you know what we're going to do?” She asked both of them.
Shining Armor shook his head.
“You're going to annihilate my tight, sopping foal hole with your breeding spear and make my brother watch?” Twilight guessed.
“Not quite, pet.” Nightmare Rarity answered. She leaned back in her chair and spread her hind legs. With her horn lit, magic formed down by her nethers, in mere seconds, her stallionhood appeared. Already hard, the long, girthy, dark-skinned appendage thwapped against her belly as she let her magic dissipate. Looking down passed the base of her shaft, she sported a hefty sack filled with two tennis ball-sized nuts, their musk already permeating, slowly filling the room with their intoxicating scent. “I'd like to see how well your brother can use his mouth... Have you ever sucked dick before Shining Armor?”
Shining nodded happily, the thick musk he was inhaling caused his own member to begin poking out from his sheath. “Mhmm.”
Nightmare Rarity cocked an eyebrow, nearly dumbstruck by the response. “Oh really? Who's?”
“I sucked my dad's cock just last week when he came to visit the Crystal Empire. He came in my mouth, then fucked Cadence until she came twice. His cum tasted good,” Shining said matter-of-factly. As if what he just said was the most normal thing in the world.
“You two have quite a strange family.” Nightmare Rarity muttered. “Well since you're quite the experienced cocksucker, come over here and fill your muzzle with my rod, Shining Armor.”
“Yes, mistress,” Shining spoke.
“Hah! Just like your sister, I didn't even have to tell you to call me that.”
Shining stood from his own chair and trotted over to the presenting, cock-endowed mare. Taking his place right between her legs, his face was now only inches away from the enticing member he was commanded to please.
Opening his maw, Shining moved his muzzle toward his objective, compelled by the charm to happily and mindlessly obey Nightmare Rarity's orders—not that he would mind willingly stuffing his muzzle full of this mare's amazing cock.
A hoof pushed on his forehead, stopping him before he could engulf his mistress's leaking tip. He gave Nightmare Rarity a confused look.
“Uh, Uh, Uh. Wait just a minute, darling.” Nightmare Rarity gestured over to Twilight. “Come over here my little cocksleeve. Come watch me ravish your brother's throat and muzzle. ”
“Okay!” Twilight cheerfully said. Making her way over quickly, she found herself just beside her brother, looking at both him and her mistress's spear, giving herself a perfect view of what would soon be Shining's performance.
The musk of her mistress began to fill her nostrils quickly, signaling her brain to get her body ready. Twilight felt a warmth radiate through her, from her head to her nethers. Her tail started to twitch ever so subtly as her triggered arousal grew while her marehood glistened with her nectar.
Seeing Twilight in position to watch, Nightmare Rarity removed her hoof from Shining's forehead and smiled down at the eager stallion. “Go on, dear, You may continue.”
With a nod, Shining opened his muzzle wide and wrapped his mouth around the thick length of musk ladened meat in front of him, forcing a faint groan to leave Nightmare Rarity's own muzzle. His mouth and tongue quickly went to work, forming a warm, wet, and tight seal, Shining worked this cock better than most mares could. He happily licked and lapped at the shaft and tip, moaning softly onto the stallionhood as he enjoyed the euphoria-inducing taste. Each time, a viscous glob of precum formed at the head of his mistress's dick, he quickly took care of it with a swish of his long, velvety smooth tongue and swallowed it without a second thought.
Shining felt a hoof firmly plant itself on the back of his head, urging him to go lower. He looked up, muzzle still full of dick, wet slurps escaping his lips as he lathered this immaculate fuckrod with his saliva. His mindless, glassy, blue-tinted eyes staring up at his mistress with a questioning look.
“You've been neglecting the lower half, Shining. Be a good boy and stretch that throat around my dick like a proper cocksleeve.”
A muffled “Yffss, Mifphtrss” came from Shining Armor as he pushed himself down lower and lower, cock disappearing into his mouth, forcing another calm and delighted grunt from Nightmare Rarity. Eventually, Shining's muzzle reached its limit, his lips snugly sat just above the medial ring, the head prodded the entrance to his throat—causing him to suppress a loud choking gag sound the best he could.
Tears welled up in the corners of his eyes, blurring his vision, the mentally charmed unicorn would not be deterred though. He began to swallow repeatedly as he pressed down even more, allowing the first few inches to take up residence within his throat and stretch it even more than Night Light normally would.
With a pace slower than a glacier, Shining gradually sank himself deeper and deeper, forcing a delighted groan from his mistress and a slobbering gag from himself as he did his best to breath through his nose.
Finally, Shining's throat now sat tightly wrapped around Nightmare Rarity's stallionhood, his nostrils firmly planted against her waist, fresh air cut off from his lungs, and his olfactory system saturated fully by her musk. Shining could feel every inch and vein along the shaft, his neck bulged out to the point you could easily make out the vivid outline of the head and medial ring lodged in his convulsing esophagus.
Nightmare Rarity grunted, pleased by the wonderful feeling of the stallion's throat bottoming out on her rod. The cacophony of wet, sloppy, choking coming from Shining Armor was music to her ears. “So, Sparkle... What do you think of your brother's performance so far.” Nightmare Rarity closed her eyes, contently humming from the extremely tight and wet massage her length was receiving.
“My big brother's throat is being swabbed by your big fat cock.” She placed a hoof onto his neck, tracing the outline of the distention. “I can see the outline of your dick in his throat. It's molding itself to become a perfect little cockwarmer, just like me, mistress.”
Nightmare Rarity cackled at Twilight's proud declaration. “You have become quite the perfect fuckpet, Sparkle.
“Thank you, mistress.” Twilight said with glassy-eyed a smile.
Nightmare's stallionhood throbbed on a particularly tight swallow performed by the alabaster stallion, stifling a moan with one hoof while the other held down firmly on Shining's head as a jolt of pleasure ran up her spine.
Not much could surpass the situation she found herself in right now. Two mentally charmed 'pets' under her complete control, leisurely relaxing while her entire thickness was worshiped by the Prince of the Crystal Empire while his little sister—the Princess of Friendship excitedly watched. Just the fact that she had pulled it off was enough to get her cock to twitch and deposit another glob of pre into Shining's stomach.
“I'm almost there, Shining. I'm going to paint your stomach, throat, and mouth whiter than your fur...”
The statement made the poor stallion moan in excitement, his own dick twitched so hard it loudly slapped his stomach. Shining pulled himself back halfway, allowing a quick moment to breath in fresh air. Just as soon as he finished inhaling, Shining slammed himself back down to the base, gulping and swallowing a few times before coming back up for air once again. With the rhythm established, the stallion began to facefuck himself with all the force and skill he could muster.
“Hahahaha, Ohhhhhh excited for my seed, are we? I expect not a drop to be spilled.” Nightmare looked over toward her fuck-puppet, Twilight, noticing the small puddle of arousal staining the carpet below her marehood—an idea came to her mind. “After I blow my load down your throat, Shining... I think I'd like to watch you ravage your little sister!”
Twilight's face perked up with excitement. “Th-thank you, mistress! I'll gladly get fucked by my own brother if It'll make you happy!”
“You and your brother hnng deserve a fun little reward after all you've done to please me.” Nightmare Rarity grabbed the back of Shining's head with both hooves and pulled him down hard onto the base of her throbbing length. “Here it comes.”She said through her own pleasured moan. The head of her cock flared as it bottomed out in Shining's throat, bulging his neck even further.
With a grunt, her warm, thick, white, sticky discharge burst forth from her magically-crafted stallionhood. Loud gulps could be heard coming from Shining's throat, swallowing quickly to make sure not a single iota of his mistress's precious seed wasn't wasted. Her heavy balls happily churned as they produced more and more fuck-fluid to be guzzled down by the seemingly desperate stallion milking the dick in his airway.
Pulse after pulse of cum poured it's way down into Shining's stomach, slowly filling him up until his flat, toned barrel, became a round, bloated, cum-filled balloon. With his stomach reaching its limit, he felt his mistress begin to pull herself back, the flared head gently scraping and swabbing his esophagus as the last few jets trickled out and lined his mouth and throat with her semen.
Once Nightmare's cock popped free from Shining's mouth, he gasped and panted for air, the salty and semi-sweet taste of her cum imprinting itself on his tongue. Shining stood there, looking up at Nightmare Rarity, the same dopey, mindless smile stuck on his muzzle. The feeling of his bloated stomach sloshing and gurgling with cum made him groan in bliss as his own stallionhood throbbed happily, the veins running along it pulsed in time with his increased heart-rate. “Th-Thank you Mistress for filling me with your seed like the stupid cumdump I am,” Shining said, through a tiny cum-burp bubbling up and out past his lips.
Nightmare chuckled and gave Shining a light pat on the head with her hoof. “You're quite welcome, darling.” Her horn lit, her magic quickly returned her nethers back to 'normal' as she glanced over toward Twilight. “My adorable slutty pet, Sparkle. Why don't you turn around and present yourself for your brother... I'm sure he's ready to demolish your sopping wet foal hole.”
Twilight nodded. “Yes, mistress.” Turning around, she braced her two front-hooves upright on top of the small circular table the three of them were enjoying their tea just moments ago. Twilight flagged her tail as high as it would go, giving anypony a clear and unfettered view of her soaked, shiny outer lips and tight, puffy purple ponut. With a small wink, her clit poked out into view, exposing itself to the brisk air as a tiny spurt of marecum trickled down her hind legs while her body trembled from the minute pleasure.
“Well, Shining... I think your sister's ready for you.” Nightmare looked down toward the prince's groin as he stood and made his way over toward Twilight, taking a quick peek at what kind of equipment Shining was packing. Her eyes nearly popped out of her head as she saw what must have been one of the biggest stallionhoods she'd ever laid eyes upon. It paled in comparison to her own, its length at least two or maybe even three inches longer, and its thickness was nearly larger than the circumference of her own hoof. His hefty sack was nothing to ignore either, each grapefruit-sized testicle jiggled and swung freely with each stride he took—at this point, it was hard to tell whether the sloshing sound was his balls yearning to unleash their reservoirs of spunk or just his still cum-bloated gullet splashing back and forth.
Once Shining reached Twilight, he hoisted himself into mounting position, front-hooves and his weight on the Alicorn's back, the head of his cock barely poking the dripping entrance to her marehood.
“Oh, Shining.” Nightmare sang with an overly pleased smile on her face.
Shining held himself just on the verge of impaling his sister's folds, turning his head to meet Nightmare Rarity's eyes.
“No need to be gentle... I'm sure Twilight wants you to be as rough as possible.”
“Yes! Big brother, I want you to wreck my pussy for mistress's pleasure!” Twilight exclaimed, waiting to pierced by the scarily large prick beneath her.
With a snicker, Nightmare leaned back in her chair ready to watch the two siblings go at it. “Well then, I think your sister has waited long enough, Shining.”
Hearing that was all he needed to hear, Shining faced the back of Twilight once again, and without warning jerked his hips forward, swiftly driving as much of his cock as he could into her well-lubricated cunt. He barely made it up to his medial ring, her tight cunny denying him further access to her depths as his thickness spread her marehood wide.
The suddenness of Shining's first thrust still caught Twilight off guard, her eyes went wide for a few moments as she gasped with her mouth hanging open, her attempts at screaming, moaning, or making any sound whatsoever were temporarily stuck in her throat. She'd never taken anything this size—even though she fantasized about her brother on nearly a daily basis. Instinctively, she clenched down, trying to mold her folds to her brother's shape. Jolts of pleasure overwhelmed her body, forcing her eyelids to flutter, her legs to tremble, and the shocked expression on her muzzle turned into a dumb, beaming open-mouthed smile.
Shining let out a pleased grunt as part of his length was wrapped up by a hot, silky-smooth, wet tunnel. His member twitched under the ministrations of Twilight's vice-like cunt clenching, a large glob of precum deposited itself inside the alicorn of friendship's pussy.
Not wanting to disappoint Nightmare Rarity, the Prince gripped tightly onto Twilight's shoulders, giving himself more leverage as he forced his mammoth length deeper with a thrust of from his legs and a pull on Twilight's shoulders.“Damn, you're fucking tight, Twily,” Shining groaned out as he strained to push himself further inside.
A small, pained squeak escaped the poor mare's muzzle, interrupting her dog-like and ragged panting. Drool had begun to dribble out from her lower mouth and hang from her chin, his medial ring spread her wider than she thought possible. The pain quickly transitioned to pleasure as she moaned in bliss from the euphoric fullness she was receiving from being impaled by her brother's cock. Her head snapped backward, vision brought toward the ceiling as she screamed out with glee, “Oh Yes! Fuck me Shiny! Stretch my slutty fuck hole until every inch of big brother's cock is inside me!” Her wings stood at attention, fluttering and flapping out of sync every so often, the extreme sensations obviously causing some sort of disconnect with certain motor skills.
With the widest part of his stallionhood enveloped by her wetness, he was determined to make her take the rest of it.
He pulled himself out slowly, inches reluctantly leaving the space that felt like heaven around his shaft. Twilight whimpered, her inner walls squeezed him tight, an attempt to keep him inside. With most of his soaked cock feeling the tingle of the brisk air in the room, he thrust back into her as hard as he could. His rod brutally plunged deeper into Twilight's cunt, making her gasp and scream as she felt like the air was being fucked out of her. He stretched her insides even more, allowing her to nearly take his entire length, only a few more inches remained dry and unlubricated by Twilight's own cunt cream.
Seeing himself nearly bottom out into his sister, Shining tried to finish his journey, pushing with his strong hind legs and pulling firmly on Twilight's shoulders. He was met with the alicorn's cervical wall resisting and denying his attempts at sinking himself into her deepest depths. The head of his dick pushed and rubbed against the wall to Twilight's womb, forcing another mixed scream of pain and pleasure to leave her muzzle.
“It hurts so good, B.B.B.F.F.! Please don't stop!”
Twilight's legs trembled, struggling to keep herself upright as her body was continuously wracked with jolts of rapturous bliss, she had rapidly become sweaty and out of breath in the short time her brother had taken her. Not that it mattered since she was happy to get fucked by Shining's battering ram of a cock for as long as her brother or her mistress desired.
“I-I-I'm so close.” Twilight moaned. She could feel herself edging closer and closer to her peak, warmth radiating all over her body, her marehood furiously leaking all over her brother's length, and her stomach coiling and tightening up like a squeezed spring, its pressure begging to be released.
Feeling her brother pull back again, she clenched down even tighter. It felt like her insides would be dragged out as the massive stallionhood left her stretched hole. “No. no. no. S-s-stay in meEEEEEEEEEE!” Twilight's plea crescendoed with a long orgasmic scream. Her eyes rolled back into her skull, only the whites of her eyes were visible. Tremors shook all across her form, the muscles in her front legs gave out to fatigue, her barrel and face collapsing on to the table she had been bracing herself on. Her jaw hung slack with her tongue lolled out, saliva slowly pooling on the tabletop and wetting her cheek.
Her brother held nothing back with this orgasm bringing thrust, feeling filled completely, his stallionhood forcefully pushed passed cervix, into her womb, and bottomed out inside her. Her entire marehood convulsed, marecum bursting forth from her plugged cunt, covering Shining's endowment with an even thicker coating and showering his balls and the fur just above his groin, creating a wet, matted, mess as his hips slammed her flank.
Her walls massaged his length while she continued to scream from the top of her lungs, an octave or two higher than normal. She felt Shining hold himself inside, grinding himself up and down, hearing him groan and his cock twitch inside, he was obviously enjoying her pussy's contractions.
“Holy shit, Twilight... Don't tell Cadence I said this, but your marehood fits me perfectly.” Shining said as Twilight's orgasm carried on.
“She's quite the screamer, isn't she?” Nightmare Rarity asked Shining with a grin.
“Yeah.” He nodded with a grunt, his hips began retreating halfway, leaving his medial ring still inside. “And her climax feels amazing on my cock.”
“Did you know your little sister is multiorgasmic?”
Shining slammed his hips forward, easily sliding himself back in fully with a loud, rough slap of hips hitting ass, causing another marecum-filled orgasm to rock Twilight's body. “Oh... Looks like you're right, mistress.” Shining felt confident that he could finally get into a rhythm and truly fuck his sister to pieces.
His hips drew back again and swiftly pounded back in with more force than before, spattering Twilight's nectar on to the floor and his groin as his balls slapped against her winking clit. Another euphoria-filled scream echoed through the room, a sound both Nightmare Rarity and Shining Armor greatly enjoyed.
“That's it, Shining!” Nightmare praised, her own hoof idly playing with her own leaky marehood. “Fuck my stupid little cocksleeve's brains out.”
“I-I-I-I can't s-s-stop CUMMING!” Twilight half babbled, half stammered out, her brain clearly straining from the nonstop pleasure chemicals overloading her body and mind.
Nightmare merely chuckled. “What is that? Three now? Won't be long before she passes out from the continuous climax.”
The unicorn prince grunted, his pussy destroying length enjoying the constant undulations of Twilight's spasming uterus. His thrusts grew stronger, brutally pounding away at his sister's cunt, the slaps from his hips hitting her flanks caused her rear to glow bright red like she had been spanked several times. Shining's pace quickened, drawing out a mind-shattering orgasm from the purple, pleasure-drunk alicorn each time he hilted inside her. He was truly ruining her now, the blindingly fast speed of his lower body was quite a marvel to watch, the slick, slimy coating of juices his entire stallionhood was steeped in helped facilitate his current tempo.
The sounds of labored breathing came from Shining while coming from Twilight was incoherent and unintelligible gibberish with a groan, grunt, or gurgle mixed in. By the sixth consecutive orgasm, her face had the 'thousand-yard stare' set in, and it spoke volumes. Her brain had shut down, her body was essentially on 'autopilot', just along for the ride until her brother finished using her. At the rate her brother was going, she wouldn't be able to walk normally for at least two weeks.
Shining was nearing his end, after fucking her sister for who knows how long, the telltale signs of his own release bubbling and bursting out of him were showing through as they became tougher to suppress. He was readying himself for his final few thrusts until the distinct feeling of magic wrapped around his ballsack broke his laser-like focus.
“Uh uh uh uh.” Nightmare Rarity chided, her magic squeezing down tightly on to Shining's nuts. “You weren't going to cum inside your sister's pussy, were you?”
Shining whimpered as he gave a dumb, glassy blue-eyed, pleading glance toward his mistress. “Y-y-y-yes, mistress, I was.” He said between breaths.
“Well, we can't let that happen, now can we?” Nightmare Rarity pulled the poor denied stallion back by his balls making sure the clamp on his sack held firm. With a wet pop, his drenched member was removed from his sister's marehood. The dripping, stretched, gaping hole from where his dick had just resided did it's best to close, clenching down on nothing but air, it still held most of the shape of Shining's cock, Twilight's clit was still visible in what seemed like a permanent wink.
“That hole is reserved for my seed only, darling... You should know better.” Her magic slowly engulfed his genitals as he dismounted the unconscious princess, a dull yet pleasurable vibration pulsed through her magic, keeping the prince on edge, making his sperm factory continue to churn out more spunk waiting to be released.
Shining groaned, this time from the gradually escalating discomfort. “B-b-but m-m-mistress... I n-need to cum. It-it-it's starting to hurt.” The pent up pressure in his balls only increased, he didn't know how he had not popped already.
Nightmare Rarity still held a hoof to her nethers, playing with herself while sitting in her chair, her magic buzzing away at Shining's groin. “Oh, I'm sure you can wait another few minutes, Shining...Besides, my little obedience charm doesn't wear off for another forty-five minutes.” Another orb of magic traveled to the tip of Shining's throbbing, desperate, precum-weeping flare. Gathering up a large, sticky muzzle full-sized glob of the stallion's pre, she levitated it in front of the prince, his eyes transfixed on the orb. “Open wide, dear.”
Shining did as he was told, opening his maw.
“Now, don't swallow until I say, I want you to enjoy the taste of yourself for a little bit while my fuckpet recovers.” The orb of pre floated into Shining's muzzle, landing squarely on his tongue as the magic dissipated and allowed the liquid to flow freely, filling the rest of his muzzle swiftly.
Shining clamped his mouth shut, not wanting to spill a drop of his own seed. With his cheeks puffed out wide like a chipmunk, he swished his pre around in his mouth, the all too familiar taste sending a euphoric buzz down his spine. His cock twitched happily, hitting his still cum-bloated stomach, causing the undigested cum to slosh around against the walls of his gut again.
“Do you enjoy the taste of your own seed too, Shining?” Nightmare Rarity asked with a grin.
“Mmmhmm,” Shining nodded, a barely visible embarrassed blush poking through on his cheeks.
“Such a naughty cumslut you are.”
Shining's blush deepened. The pre in his mouth still swirled around, his tongue danced around trying to enjoy the taste as much as he could, it coated every inch of his muzzle with the viscous, sticky ichor.
Twilight began to stir, taking both ponies attention. The pair looked over toward the mare, listening to her groan and her body weakly shuffle down on the floor.
“Looks, like my pet is recovering quicker than I expected...Sparkle, you continue to impress me...” Glancing back to her current object of 'torment' Nightmare Rarity smiled. “Go on and swallow, Shining. Tell me how much you liked it.”
With an audible gulp, Shining swallowed his seed, smacking his lips and opening his mouth as all of it traveled down his throat. “Thank you, mistress. It tasted great but not as yummy as your seed.”
Nightmare Rarity laughed. “I expected no other answer, pet.” Her magic let go of Shining's rod. “Go on and have a seat on the floor, dear. You won't be needing to do much work to get yourself off... I think you've earned this reward.”
Shining took a seat on the floor, away from the table they had all been gathered around. His titanic cock still stood tall and proud, glistening from the thick coating of Twilight's marecum.
Once Shining had taken his place on the floor, Nightmare Rarity turned her attention back to the groaning and disheveled alicorn. Her horn glowed, magic shot from her horn and surrounded Twilight, a mix between a pain suppression spell and an energy restoration spell hit the princess like a ton of bricks, jolting her upright and awake in a fraction of a second.
Twilight's eyes still held the same traits as her brother, glowing blue and glass-like. Her body was a complete train wreck, her fur was matted and sticky from the sweat and sex fluids, her mane was a frazzled unkempt mess, and her lower body was lightly sore and sopping wet.
She glanced around the room, her eyes falling upon the disapproving look of her mistress. “What's wrong mistress? Is everything okay?”
Nightmare Rarity shook her head. “Tsk, tsk, tsk, you've been quite the selfish little sister, Sparkle.”
“What do you mean, mistress?” Twilight asked, her expression growing concerned.
“I let your brother fuck you until your brain is mush and YOU can't even make him cum... What kind of terrible cocksleeve are you?”
“I'm sorry, I'm sorry, I'm sorry, mistress. Please let me try again, I promise I won't let you or my brother down this time,” Twilight groveled at the hooves of Nightmare Rarity.
“I know you won't, Sparkle...” Nightmare Rarity said with her smug grin. “But how do you suppose you're going to go about making your brother cum? Your cunt is basically useless right now, I bet your brother wouldn't feel a thing now... And your mouth certainly wouldn't be able to fit half of him...”
Twilight's brows furrowed in thought, trying to figure out a way to make her poor brother cum.
After a few moments of mental problem solving, Twilight came to a solution she thought was fool-proof, and hopefully one her mistress would approve of. “I know! I can use my tail hole...I'm sure big brother would cum after popping my anal cherry.” Twilight said proudly as if she'd just solved the hardest problem known to all ponykind.
A pleased nod came from Nightmare Rarity. “Go on then, Sparkle...” A burst of magic snaked its way to Twilight's ponut, cool, soothing lubricant lathered itself all over her untouched and tightest hole thoroughly. “Don't let your brother down.”
Twilight made her way over towards her brother, his stallionhood throbbing and standing upright as he sat patiently on the floor. She stood between his groin and turned around, giving him a perfect view of her tight, puffy anal ring with her tail flagged. Slowly, she squatted down on her hind legs, lining the entrance to her ass up with his wide head. Her ponut finally settled itself atop the tip of his cock—like it was giving it a kiss.
Twilight closed her eyes as she began to push more weight down against the tip prodding her entrance. A hiss escaped her lips, the intense sensation of her anal ring stretching around her brother's flare sent sparks flying from her horn, wings flaring out stiffly—she didn't know why she wasn't feeling any pain but that didn't matter, all that mattered was making her brother cum.
With a gasp, Twilight's anus made the head of Shining's cock disappear, sliding in with relative ease due to the plethora of lube on both Shining's cock and inside Twilight. The entrance to her tail hole clenched down snugly on the shaft, forcing a moan from her muzzle, the unfamiliar feeling sent her brain's pleasure center into a frenzy.
Inch by inch, she lowered herself down, spreading her anus and snaking her intestines with her brother's girth, the chorus of pleased grunts and groans filled the air as Shining sat there enjoying her sister's efforts. It wasn't long before she felt her ring bump up against his own, if she could fit his medial ring in her then nothing would be holding her back from riding her brother fully. There was no doubt in her mind that she would milk him dry if she took his full length up her tail hole.
With a deep breath, Twilight let her weight push against his medial ring, feeling her asshole struggling to spread wide enough to accommodate him. What should have felt painful was only a dull tingle to her pain receptors. In an instant, she felt Shining's ring pop inside, setting off a mixed moan between the two siblings.
With her brother's medial ring conquered, plugging her tail hole like a true wanton slut was now a breeze. She was determined to give her brother the ride of his life, she held herself up, over half of her brother's shaft filling her rectum, her hindlegs shaking from the strain and pleasure. She turned her head to look back toward Shining. “How's it feel, big brother?”
“Ohhhh.” He grunted, his eyes closed, biting his lower lip, enjoying the strange rhythm of convulsing her ass was massaging his length with. “Your ass is so fucking tight, Twily. I'm gonna pop soon.”
Spurred on by the prospect of her brother's cum, Twilight plunged herself down, taking the remaining length of Shining's shaft with ease, causing Shining's eyes to nearly pop out of his skull in shock and a spurt of precum to glaze her rectal walls. Her flanks slapped loudly against her brother's groan, the mounds of fat jiggling from the impact. She sat there grinding his cock inside her tight little ass, the outline to the head of his stallionhood was just barely visible in her stomach. She shuddered at the sight, eyelids fluttering as her belly was prodded outward from the complete stuffing she was taking.
She could feel her brother getting close, if the spurt she just felt inside her was any indication, then she wouldn't be waiting much longer to have her ass filled with his foal batter. A slippery, wet 'Schlick' could be heard as Twilight lifted herself up, the massive length impaling her flank slid out of her smoothly until just the first few inches remained.
With any warning, she dropped herself back on to it, taking it in one deep thrust. Both brother and sister gasped, the air taken from their lungs as the sudden bolt of pleasure shocked their systems. The pair shivered in unison, Twilight's marehood spurted excitedly, her juices staining the floor and fur along her thighs while Shining's stallionhood shot another dollop of pre up inside her.
Twilight continued this pattern, up and down she went, quickly riding her brother's entire length for the next few minutes. The wet sounds of her brother's member sawing in and out of her stretched and abused tail hole graced the room. She couldn't get enough of this feeling, the feeling of complete fullness while she mercilessly pounded her rump.
One final hilt brought out a scream from Twilight and a loud groan from Shining. Twilight felt her brother's balls begin to empty themselves inside her, unleashing a thick torrent of seed shooting into her anus. Twilight closed her own eyes, riding the wave of pleasure and grinding herself down as deep as she could on to her brother, milking him for all he was worth.
Twilight lost count of how many pulses of jizz exited Shining's pent up rod, but by the time he had tapered off into his final few weaker spurts, she had a little round bulge coming from her stomach and the felt like she had just added five pounds on.
She looked back to her brother, cock still stuck in her butt. He was passed out, quietly snoring, exhausted from the marathon-like fucking session.
A wave of fatigue crept its way on to Twilight body as well, she leaned back, closed her eyes, and sighed, her ass still plugged by Shining's length as she prepared to nap within his embrace.
“Go on, my pets. Sleep well... By the time you wake up, each of you will be cleaned up and have no recollection of what happened.” Nightmare Rarity laughed. “Any memories will be written off as just 'strange' dreams.” Her magic began cleaning up the room, removing stains and clearing the table of the dishes that still sat atop it. “I'm sure we'll all find another time to have some more 'fun' together.” She said, walking out of the room, leaving the two siblings to stew in their juices.
