Stay With Me

Somewhere, in a far off place, a mighty pony presided dramatically over a field of battle. Her vanquished foes, nearly an entire army of changelings, were piled up under her hooves, and the rivers ran putrid green with their blood. With fire streaking the skies, those of her allies who still drew breath were all around her, chanting and singing songs in the glory of their leader’s name.

Her name.

Bedecked in the gleaming glow of her finely-plumed helm and sharp metal plates, she lit her horn and held aloft the spear and shield that had been her constant companions in victory. She threw her head back and called to the heavens, speeding the souls of the fallen into the promise of their next, exalted lives.

Everything went red then, as though she had closed her eyes against the sun on a clear, warm spring day. Addled with confusion, the warrior-princess accepted the new set of circumstances, her breathing beginning to relax...until the sudden pressure of a hoof over her muzzle snorted her abruptly awake.

“Mmwhah!?”

She coughed, pulling roughly away from the hoof until she came up against something solid just behind her. Still battling against sudden consciousness, she spun under her sheets and sent a foreleg flailing repeatedly at the object, intent upon living up to the might of her dream-persona and vanquishing whatever foe dared to stand in her way.

“Hey, hey!” A voice called through stifled giggles. “Gleaming! You killed the bad guys! All my base are belong to you! Stop already!”

Gleaming Shield finally found the wherewithal to crack the dry lids that contained her sandy cyan eyes. Her assault ceased, her eyes and mind focusing on the image that lay next to her in bed. Violet eyes with a face to match, a horn of his own, and an infuriatingly smug smirk.

Gleaming rolled her eyes and flopped back on her opposite side, facing away from the interloper again. She curled herself tighter into the fetal position, and took to staring blankly out into the quiet, peaceful image of Canterlot skies beyond the balcony of her bedroom.

“Go away Dusk,” She rumbled, buried now up to her neck in soft warmth. “I’m trying to sleep.”

“It’s like nine already!” The voice argued bemusedly. “Aren’t you guards supposed to be up with the sun or however that goes?”

Gleaming felt a hoof on her head. She shut her eyes tightly just for spite, returning her vision to the red haze of the sun showing beyond her eyelids. “I’m not going to be a guard if you keep bothering me when I’m trying to sleep,” she huffed. “Gimmie a break. I leave for basic training in three days and I would like to enjoy my last three mornings ever of sleeping in! So go bother mom or dad or something!”

“I broke my bed,” Dusk Shine, Gleaming’s little brother, offered by way of explanation. “So mom says I have to sleep with you.”

“Bad lie,” Gleaming muttered.

“My bed exploded in an earthquake!”

“Worse lie.”

“There was an accident!” Dusk ‘pleaded’. “A terrible flood! I forgot my keys! Somepony stole my cart! A famine! A plague! And I had to donate my bedroom for the good of all ponykind!” He pushed down with the hoof on his sister’s head. “Just like you would do! So can I stay now?”

Gleaming shook her head violently, tousling her long cerulean mane to shake off the hoof that had taken root atop her skull. “No you cannot stay!” She insisted, yanking around herself what covers her brother didn’t already have pinned down. “And if you so much as touch me again with those cold hooves of yours, I’ll buck you so hard that even your future sons will be born fillies!”

Dusk wedged his elbow into a crack between the pillows and rested his cheek in his hoof. “Oh come on. I’m sorry. You know you’re my B.S.B.F.F.”

Gleaming’s brow furrowed with the grumpiness of one who had been woken prematurely. “Just remember the big sister part.”

Dusk yawned and amused himself by glancing around his big sister’s bedroom. A perfect, obsessive order to everything, and everything in its place. “You know-” He smacked his lips on the heels of another lazy yawn, “I remember when this room was such a mess that mom was on you practically every day after school to get it cleaned up. Now it kinda reminds me of, well...me.”

Gleaming didn’t move a muscle. “Get used to it,” she admonished. “Guards live prim and proper, clean lives. I’m devoting myself to the betterment of Equestria. It has to show in everything I do.”

Dusk’s eyes traced the gentle curvature of his big sister’s small, wiry body. The sheet that contained her spread wide over every hill, and bunched down deep into every valley. It was...distressingly thin, and Dusk found he could make out nearly every contour of her curled up little legs.

“Tch,” he huffed, brushing a bit of his short, straight mane out of his eyes. “Don’t try so hard to be somepony you’re not.”

Her only reply was soft snoring; the oscillating sound accompanying the melodious birdsong and distant sounds of ponies at their toil. Dusk put his attention on the hypnotic rising and falling of Gleaming’s side, and turned his thoughts towards the many days they’d spent together. Being the younger, he had never known a time when she hadn’t been there. He used to look up to her both physically and mentally, but even when all of that went into reverse, he still took comfort in her guiding hoof and her encouragement as he whiled away dark hours huddled around a bench with his studies in magic. His entire life, he could never remember being separated from his big sister for more than a few days.

And now, she was going away.

His rock. The light in his storm. She was going to be gone for months, possibly more, only to come back for a short time, vanish again for just as long, and then what? Dusk knew his sister as a fun-loving and easy-going type, but she always applied herself when it was important. Always met expectations. She would never fail, and that Celestia-be-damned reserve officer’s education in school had practically turned her into a cadet already. Before long, Dusk simply knew that he would be bidding his dear sister farewell to live in the barracks, and she would only come home for Hearthswarming.

What was he supposed to do without her?

His hoof found her shoulder, and he watched as it traveled down the first valley to her waist, up her ample, feminine hip, and down the taper of her hind leg. There was a softness there he had never really given her credit for, and he treated his hoof to skiing her slopes as they expanded and contracted rhythmically with her breathing.

He was waiting. Patiently waiting. When her snore deepened, he could feel the curl of his lip rise.

Lacking the bulk of stallions his age and size, Dusk slipped his lithe form under the thin sheet and drew his muzzle just up behind his sister’s ear. The warmth was inviting, and the faint scent of her lavender shampoo filled his nostrils from mere inches away. He reveled in it, indulging in memories tied to his sense of smell by burying his nose in the side of her head and taking a long draw of her mane.

“Gleeeeamy...” he sang, the soft tenor of his voice resonating in her snow white ear and making it twitch. “Gleeeamy...”

Gleaming snorted. Dusk’s lips were mere inches from her ear.

“Wake up, Gleamy...” he whispered. “Sleeping in is making you all weak. That’s no good for a soldier. Wake up for me...”

“G’way,” Gleaming muttered, her brow furrowing above her closed eyes. “Dusszk g’way. Mseepin’...”

Dusk’s foreleg passed under the surface of the sheet like a submarine until it came into its intended port - the fuzzy stillness of Gleaming’s shoulder. Something about touching her without a thinly-spun layer of cotton in the way skipped a beat of his heart, and he repeated his previous gesture, running down the length of her side and back up again. His hoof skimmed the surface of her coat, tracing her topography like a master cartographer.

Gleaming Shield was the type of pony most mares were jealous of. The gift of her strong metabolism burned off the calories without much effort, but it had the added effect of making her radiate heat like a phoenix. Dusk pressed his body up against his sister, enjoying the warmth and curling his hind legs with the sweep of the ball she was rolled into. He wormed his foreleg around her until he found a downy tuft of unicorn chest fluff to play with.

“I don’t know what good you think it’s going to do, putting on an act like this,” he cooed in her ear, drawing tiny circles on her chest with the tip of his hoof. “Wearing all that bulky armor and soldiering around just doesn’t...suit a body like yours.”

Gleaming wriggled her muzzle and sniffed at a wayward feather that had seen fit to poke its way through the case of her pillow.

“You’re adorable when you’re sleeping, sis,” Dusk murmured.

Gleaming Shield grinned. Far away, she was a conquering general - a one mare hit-squad that had earned the undying respect of her entire nation. She again stood atop a pile of her foes one moment...but in the next, she felt warm water being poured over her neck. She sniffed again, her ears and a foreleg twitching as Dusk ran his thick, equine tongue along her shoulder. He paused to plant a few soft kisses at the slack pool of flesh where her collarbone met her neck, and then wrote his name in cursive up her nape. He finished each letter with another peck until he found the stiffness of her jaw. As he drew his way towards her muzzle, her head instinctively rose, her eyes shutting tighter.

A nearly inaudible coo escaped her.

Smiling inwardly, Dusk brushed her lips with his just long enough to enjoy watching her pucker up and reach out - before pulling teasingly away to trace the outline of her ear with his tongue. He favored it with an experimental chew; caught between his teeth, the thin flap of flesh tried in vain to pull away.

“What are you dreaming about?” Dusk finally freed the ear and whispered into it. “Saving Equestria?” He shook his head and made a clucking sound with his tongue. “You know, when we’re all dizzy with sleep in the morning, our brains are too weak to keep up the battle against our bodies. That’s when we’re the most...honest.”

As he spoke, Dusk wormed his other foreleg under Gleaming’s pillow. His hoof surfaced under her cheek, and with a delicate push, he turned her face to the ceiling and pressed another kiss into the side of her muzzle. His lips parted, and his tongue matted her coat there, just as it had all over her neck.

In her mind, Gleaming Shield was the Buccaneer Valeria who had finally found her Conan on a rough, churning sea. Her lips twisted in a silly, dreamy grin, her eyelids slowly parting like space doors from her brother’s favorite sci-fi novel. Dusk couldn’t help but chuckle,

“Mmmmn...” Gleaming moaned groggily, fighting the second onslaught of sleep, “...whuh...?”

Dusk Shine took his cue. Slipping his forelegs from their strategic positions, he planted one hoof firmly on the mattress, just to either side of his ‘big’ sister’s head. Using the leverage to pull himself up, his hind legs were soon straddling her hips. He stood tall, the sheet fluttering from his back and sliding all the way down to her pasterns.

Gleaming Shield fought to bring the world into focus. Looming over her was an undefined purple shape, with eyes that were boring into her and hot breath leaking from its nostrils. She squirmed and made to bat at it; to drive it away. Dusk dipped his head and let the ineffectual blow hit him in the jaw. He giggled and pressed his muzzle into the stark white hoof that had attacked him, lowering it to the mattress and pinning it there with one of his own. Gleaming sent another assault at her target, but it was just as futile; soon both her forelegs were pinned to either side of her head by those of her little brother.

She struggled; pushed at her living bonds to no avail. Leverage was not on her side, and Dusk demonstrated her predicament by firmly pushing down on her pinned legs.

“Shhhh, shhhh...” Dusk chided. “You’re not as strong as you think. Not as strong as me.” He lit his horn, the raspberry glow of his magic catching her tiny midsection and pulling her out of the twisted, sideways bind she’d gotten herself into trying to fend him off, until she was all the way on her back. “Better.”

“D-Dusk...” Gleaming whimpered.

He bent his head until his muzzle was inches from hers and stared into her groggy eyes.

“You don’t really even want to fight me, do you,” he presented the statement as fact rather than question. “You’re all sleepy and weak, and your body is being honest about what you want.”

“Dusk, no...” Gleaming whined, struggling again, her cerulean mane pooled in scraggly waves around her head. “D-don’t--”

“Shhh,” Dusk made the sound again and reached in to nuzzle his sister’s cheek. “I know what you’re weak against. Don’t think I don’t know how you kiss the bathroom mirror sometimes. I wonder how long you can deny yourself before you just can’t stand it anymore? When will you reach your limit? How about…now?”

Gleaming Shield had always envied her brother’s coat. The lavender all over his cheeks made it easy to conceal how he was feeling, whereas her coloring made hiding even the slightest redness downright impossible. Now he was staring right at her, and even with her eyes averted she could feel his scrutinizing gaze, taking in her expression and knowing her mind from it.

His horn lit again. This time Gleaming felt a little push on her chin. Before she could react he buried his lips into hers. Her eyes opened wide and she let out a muffled yelp that he took full advantage of, pressing his tongue into her mouth the moment her lips parted. He fed her the damp, wriggling probe until she nearly gagged. She struggled, but her movements eventually slowed, and he murmured with approval when he felt her begin to suckle on his offering. A full minute felt to Gleaming like an eternity, and when Dusk finally pulled out, his departure was marked by a lewd smacking and swirling of their tongues together.

Dusk’s grin was broad. His big sister, perhaps not quite so ‘big’ as before, was panting up at him as though she’d just galloped a marathon, her cyan eyes lidded and heavy with exertion.

“I know, I know,” Dusk whispered. “You’re trying to find the energy but it’s just not there. I know how you are with kisses. How they just...sap the resistance right out of you.” He drew in close, letting his breath dance over the wetness still at her neck, “But you’re not quite weak enough yet...”

She drew her head back as far as the pillow would allow, but he moved in and claimed her lips again with ease, her tense neck muscles slackening instantly as he continued to consume her resolve. Gleaming felt the steadfastness she had drilled into her mind for weeks seep away; draining like magic from one enchanted vessel to another. He lit his horn and touched it to hers, her sapphire magic coming to life and mixing with his raspberry hue as the two spires rubbed slowly into one another.

“Mmn....nn...” Gleaming murmured into the kiss, and Dusk felt a shiver run through her as the charge of her defiant batteries began to run low. He parted the contact just to listen to her lungs deflate, and then pressed in a third time, prying her open and filling her with his writhing organ.

Dusk pulled back to admire his handiwork. Gleaming Shield, his smaller, bigger sister, was flat on her back, her mane cascading forth in waves around her head and neck. Her chest heaved with entrancing puffs, and her coat was marred in places where he had kissed and nibbled on her.

His favorite reaction by far was in her eyes. She stared dumbly up at him through foggy, one-way windows that gave him a clear view of the soul within. He freed one of her forelegs and ran his hoof through her mane, bringing it down to caress her cheek and subtly keep her face forward; her eyes on him. Rooting her in place with his stare, he drew the hoof down her neck and across her chest, to the forbidden valley between her thighs that he had never before blazed a trail through. He lifted his hind legs one by one, stepping between hers and pushing gently to scoot them out past his own.

Gleaming’s legs, granted parole, didn’t try to escape.

“Come on…open up...” His syrupy voice encouraged as he pushed on one thigh and then the other. She slid her hind legs apart with little resistance, and he treated himself to another whiff of her mane, kissing her forehead by way of reward. “That’s it…good mare.” As soon as the snowfields parted, he dipped his hoof into the warm blossom they concealed, reveling in the slight jump and hard exhale the move elicited in her.

“You like that, don’t you?”

Gleaming bit her lower lip, stubbornly refusing to give away her words. In response, Dusk began turning his hoof in little circles, pressing it just a little bit into her flower and then out again…tracing her walls and letting her swallow him just a tiny bit.

“You like that,” he repeated coolly, “Don’t you?”

Gleaming shut her eyes tightly as a hissing whimper escaped through the sides of her mouth. Soft whines began to leak from her lips like air from a balloon – once set free, they were impossible to contain. Her cheeks flushing hotter, she had little choice but to open her mouth and let her reply free before the pressure made her burst.

“…o-oh…”

Dusk turned his hoof in slow circles for a while longer. When he was satisfied that his sister had lubricated it for him, he pulled away, brought the hoof to his muzzle, and made a show of taking a deep breath as he licked her juices from it.

“Oh ho, you’re in heat,” He casually observed. “We might be far removed from stone-age ponies, but I can smell it on you still.”

“S’why…” Gleaming muttered, barely audible, “…s’why you needta stop…”

Dusk ignored the request and went on, waving around the dampened hoof as he spoke. “The only real difference is our ‘civilization’, don’t you think? Movies, fireplaces, wagon wheels…but we’re still the same ponies.” He brought the hoof down and gingerly painted the tip of his sister’s muzzle with her own scent, as though he were applying stage makeup.

“We have so many first world concerns, sis, but we’re still ponies. Your needs take over, but there’s no stallion around to catch your scent. So before you know it, you’re lying in bed with your hoof between your legs, grunting and panting, hoping nopony hears you while you rub yourself, make a mess…” He kept the hoof there until Gleaming took her next breath, “…and dream about some big stallion standing over you, filling you and pounding you silly until there’s nothing but lust rattling around between your ears.”

Using his natural tendency to over-explain things, he continued. “Do you know why it’s easier for a mare to have a bunch of orgasms, while a stallion usually only has just one?” As he spoke, he dipped his hoof into her flower again, eliciting another series of soft moans and needy lubrication that he painted her cheeks and chin with. “Breeding, of course. Nature wants us to breed, and our attempts to resist are nothing but a losing battle. You climax over and over again because your body is whispering to you. It’s saying—” He drew near, “‘Psst, hey…you’re a ripe mare. It’s time to get pregnant. Let this stallion make you pregnant.’ Your body is keeping you interested. Keeping you in place, so he can root you as long as he needs to, until it’s time to…” he placed the hoof on her tummy, “…leave his mark.”

Gleaming twitched.

“Look at you,” Dusk smiled. “You’re sleepy, weak, soft, and needy. How do you think you’re going to get by at guard school if you can’t rub yourself silly every morning? You’re lucky I’m such an accommodating brother. Nature doesn’t care who the stallion is, after all.”

Gleaming blinked, her consciousness roused by a new sensation. At first there had been nothing but soft pony tummy against soft pony tummy. He pressed into her, and now she could feel the stiff twitch extending halfway up her stomach as Dusk let out a terse breath of his own.

“We c-can’t…” Gleaming whispered, the words fighting for control, “…c-can’t do th-that…”

Dusk rolled his hips, humping his erection into his sister’s yielding tummyflesh as he put his hoof to her cheek again. Despite her protest, she instinctively nuzzled the hoof while trying to make the move look accidental.

“Sure we can,” Dusk cooed. “We’re a mare and a stallion. You’re all wet and horny…” he humped her again, “…I’m nice and thick and hard…just what you’ve been wanting so bad. And we’re both alone in bed together. It’s just nature. Don’t fight it.”

Dusk Shine sat up and stretched dramatically, arching his back. His dark stallionhood, proudly curving out from its fuzzy sheathe, bounced out from its prison between them and prowled eagerly about his sister’s chest. He scooted up to straddle her waist, waited a few seconds, and peered down to see her throwing sidelong glances at the twitching flare that was pointed at her chin.

“Mmhmm,” Dusk grinned. “Here you go.”

He scooted forward until his wine-colored spire cast a shadow between her eyes, and then slowly sat, pressing his squishy testicles over her face.

“Nice deep breath sis,” he encouraged, reaching back to toy with her damp opening again. “Deep, deep breaths of stallion…that’s what you need right now…”

Enveloped in the velvety fur of Dusk’s scrotum, Gleaming’s muzzle dutifully sent breath after breath of his intoxicating musk straight to her brain. She wormed her snout deeper between the weight of his orbs, letting them spread around her as she drew deeply of his scent.

“That’s right, let it seep into your mind,” Dusk’s voice emanated from somewhere above. “But you can do more, can’t you?” She felt him digging at her marehood again; pressing in and fondling the spot just inside her channel, only to retreat and leave her wanting.

“Gotta work for more, sis…”

For a moment, there was nothing. Then, Dusk Shine felt the tiniest probing sensation somewhere between the tightening wrinkles that contained his testicles. It began as little more than a poke, but soon enough, a writhing wetness was caressing one orb, drawing it slowly into his big sister’s maw.

“G-good…” Dusk muttered, constantly changing the pattern of the pressure between Gleaming’s legs so she couldn’t keep up. “That’s it…take it in. Be a good mare and be gentle with it…”

Gleaming invited the musky scrotum into her mouth, squeezing what lay inside and caressing its oval shape with her tongue. Her thoughts were flooded with a gooey, creamy lust that congealed at the corners of her mind and stuck to her reason, dragging her down into a delicious, cloying fog. She favored one orb with playful hugs, set it free, and then slathered its twin in the same attentions.

“Show brother…how much you care for him…” Dusk managed. He pulled back his hips, his heavy sack slipping down Gleaming’s chin, and placed the base of his erection right between her eyes. She stared up at him, his taut member masking her expression. Her lips parted again, and he slid back more, her tongue molding to cup his penis as it traveled down her face, pausing at his medial ring.

“That part is to make sure your stallion stays inside you,” Dusk instructed, “So the seeding is nice and deep…”

Gleaming nibbled on her brother’s ring with undisguised glee. She traced the roughness of his flare, finding a tiny hole at his broad tip that she probed with the tip of her tongue. Her reward was a slippery, clear substance that oozed forth and passed into her. Dusk’s erection twitched, and he purposefully lifted it up just to gently bap her in the face with it.

“Gleaaaamyyyy…”

Gleaming Shield reached out to lick him again, but his toy changed positions until his dribbling tip was prodding at her lips. She closed her mouth and looked up at him.

“That’s…” she flattened her ears, “…that’s prolly too much…”

Dusk’s grin broadened. His hoof was in her mane again, soothing her with gentle petting. His tip resumed its prodding as his voice dropped to a soft, honeysuckle buzz.

“Come on, sis…open wide…”

“B-but...you’re my--”

“Shhh,” Dusk sang. “Open…let it inside you…”

The flattened tip of Dusk’s stallionhood mooshed against Gleaming’s lips. The moment she opened her mouth to protest again, he pushed his way inside, feeding her his length inch by inch until she could no longer speak. Pacified, she looked up at him, her brows upturned, until he completed his invasion; his balls sprawling once again over her chin. Her features contorted as if to gag, but he touched her forehead and simply smiled.

“You’re training to be a guard, aren’t you? Show me that discipline you’ve been building up.”

Gleaming mumbled something in a harsh tone. The meaning was lost on her brother, who received the message only as pleasant vibrations all around his girth. He leaned forward, placing his hooves on the headboard; forcing his sister to raise her head until her throat was one straight passage all the way down.

“Mnf!” Gleaming complained. Dusk replied by pushing down until her muzzle touched the purple fur over his stomach.

“Take it…” he instructed. “Take it nice and deep down inside you. Don’t you want it deep inside you?”

Gleaming said nothing. Her lips formed into a proper o-shape, and Dusk soon felt her tongue dancing lightly around his ring.

“There you go,” he offered. “Good sister. Deep down…let it fill you up, take your voice away, and give you dirty thoughts instead…”

With nowhere for her head to go, Gleaming found herself at the mercy of her little brother’s movements. He pulled back, let her breathe..and then pushed forward again on the cusp of her inhalation, letting her draw in both needed oxygen and his needed gift. All the while, she tasted him and felt his contours, breathing when he allowed it; slipping her lips around his ring and using it as leverage to make a tight seal for suckling.

“Nnh…” Dusk muttered, increasing the pace of his pistoning. “…f-feel good s-sucking on your brother…? You do that so well, I wonder what your dreams are really about...”

Gleaming flicked her ear at the comment - some passive display of annoyance - as she traced each throbbing vein with the tip of her tongue. She was finally feeling some small measure of revenge for the entire morning. The sudden transition from sleep had left her mind fertile with imagery, and she chose a fantasy to focus on - her rippled, chiseled stallion lover who was most definitely not her own brother, laying claim to her in a way most ponies would never know. His girth was a presence she could not deny, and she worked hard at his pleasure - drawing deeply of him and dutifully swallowing down each little offering he favored her with.

“Ngh...” Dusk’s voice utterly shattered Gleaming’s attempt to enjoy this while pretending it wasn’t happening. “Hey now, not so fast...we haven’t even gotten to the real prize yet.”

To her regret, his penis receded until Gleaming was left with nothing upon which to feed. She blinked, nearly going cross-eyed at the thick, bulbous flare staring back at her, dribbling fluid and twitching with appreciation for her work. Beyond it, slightly out of focus, was Dusk Shine - his hooves on his hips and a smart grin on his face.

“A-alright,” She managed as she sought to replace her stolen breath, “So I...think weird thoughts in the morning. Y-you’ve made your point. Let me up.”

Dusk folded his forelegs over his chest and didn’t move. Gleaming squinted.

“I...I said let me up.”

Gleaming Shield yelped when two thunderous hooves came heavily down to either side of her head a second time. Dusk’s muzzle was there, and before she could protest he captured her lips again, his kiss rougher and deeper than before. She murmured against it, but it was like a bucket of kerosene being dumped on a fire. She never even noticed him pressing her hooves down with his own again, but the force of the pinning and the depth of the suckling aroused in her a high-pitched squeal that she’d never be able to play down later.

When Dusk pulled back, his sister was again a mask of perspiration, blush, and softly-lidded bedroom eyes. He took her ear again, tugging on it with his teeth.

“Do you really want me to stop, sis? Nopony has to know.”

Gleaming hesitated.

“...no.”

“No?” Dusk asked.

“No...” Gleaming’s voice was barely audible, and it rode the craggy fissures of her broken breathing. “...d-don’t...stop.”

Gleaming instantly found herself no longer pinned to the bed. Dusk had slipped down to her side, and he was futzing with the thin sheet that had become tangled somewhere around her pasterns. She glanced at the window. A pleasant spring day. She could - she should get up, run through the shower, and begin the prim, proper, and stoic trot through her day that would soon become a requirement rather than mere practice.

It would be that way for the rest of her life.

At his bidding, she rolled onto her side and allowed him to wrap his warm, spooning body around hers, his foreleg coming down over her chest securely. At the small of her back, she felt the barb of his penis, poking eagerly; looking for a cozy, wet place to call home. His muzzle was at her ear, and he breathed warm air over her cheek.

“Just let it happen...” He encouraged again, licking her neck as the hoof on her chest traveled down her side. He hooked it under her hip and pulled, raising her hind leg until her hoof pointed towards the silent window.

“Th..the drawer.” Gleaming sighed with mortification.

“Hmm?”

“The drawer,” she repeated, a certain timidness in her voice. “They’re in the nightstand drawer.”

Catching on, Dusk chuckled frustratingly. “And why do you have those in your drawer, hmm? You don’t even have a stallionfriend.”

Gleaming bowed her head in surrender. Eyes closed, she admitted, “Guards are supposed to be prepared for anything.”

Dusk did his best, but in the end he simply couldn’t suppress a chortle. He received a shot in the ribs from his sister’s elbow for his trouble, but he was there at her neck again immediately, drawing his tongue along her coat until the elbow retreated.

“We aren’t going to need those,” He stated plainly.

Gleaming’s horn was already glowing, and the handle of the drawer had already been pulled back. Her eyes widened. “Wh-what...?”

“You heard me~” Dusk sang into her ear. “Close the drawer, Gleamyyyy...”

“D-don’t be ridiculous,” Gleaming’s eyes darted between her outstretched hind leg and the drawer, where she kept a short strip of condoms hidden under her guard training manual. “Of course we need--”

She watched as the magic aura around the drawer handle shifted from sapphire to raspberry. She concentrated, furrowing her brow and pushing more of her aura into the task, but the drawer would open no further.

“Dusk...cut it out...”

“Sis,” he cooed, “You know you can’t beat me at magic.” He pulled his punches, letting her keep the drawer open as he reached up to draw his tongue the full length of her horn, from base to tip.

Gleaming shuddered. Fought for concentration.

“Turn it off, Gleamy...” Dusk sang. He slipped his head up and swallowed the tip of her horn, fellating the tapered magic device as though drinking her magic from a straw.

“...a-ahh...”

Much to her chagrin, Gleaming Shield was among those select unicorns in Equestria who were unfortunately oversensitive in the horn area. By the time her brother was halfway to kissing her forehead, both their ears swiveled to the satisfying click of the drawer closing again. Dusk pursed his lips and squeezed his way off of her, eliciting another involuntary squeal from the little mare he had enveloped.

“Better,” he whispered. His hoof was on hers, and he pulled her leg down, hooking it around her hip where his had been a moment before. “Your magic tastes like spearmint, you know. Hold yourself open for me.”

She tightened her grip around herself obediently when she felt his spire poking at her depths, so slick now that she nearly swallowed him the instant they touched.

But Dusk wasn’t ready yet. He was there again. At her ear, his voice like saccharine.

“I’m going to slip inside you now. Just me. No protection. No barriers between us.”

She felt the wet pop of his flare stretching her. She whined sharply and pressed her head back into his neck.

“Shh...let it happen. We’re gonna make love, sis. Just like this. Every morning from now on...”

He sank deeper. She jumped when his ring tickled her button in passing.

“...nngh...D-dusk...”

“Shhhhhh...” Dusk Shine repeated. “You’re a strong mare, but you work too hard, and you deny yourself too much. Your brother is going to help you find your release, every day, and every time you need it. Just come to me, and I’ll know.”

His hips finally met hers, his testicles dampening with her lubrication. Ever so slowly he drew back, popped his ring out, and thrust it back in again to the tune of audible slaps.

“Hahh...” Gleaming breathed, pulling on her hip to hike her leg up more. “...o-okay, b-but...” she swallowed. Tried again. “...I-I’m in heat...y-you can’t...f-finish...”

Dusk took Gleaming’s ear into his mouth and held it as he hilted her again, cutting her words off with stammered cries.

“You don’t have to worry about that,” Dusk slipped his hoof down to his big sister’s yielding tummy. “It’s just nature. You don’t need to be a guard. Soon you’re gonna have a nice fresh batch of warm, fertile semen inside you. We’ll put a new one there every day until your tummy swells up and you stay with me forever.”

Gleaming let out a high-pitched whinny, lathering her brother’s penis with moist, satin caresses even as she voiced a weak protest. “...n-no...Dusk, y-you can’t...”

“Shhhhhhhhh. Quiet now...let your big brother take care of you. I am a bigger pony than you, after all. Doesn’t that make me--” He thrust in sharply, “Your big brother?”

“..ngahh...!” Gleaming tensed and bore down, gripping him tightly. “...ahh...y-you...”

“Doesn’t it?”

He pistoned, plunging in and out in rapid succession half a dozen times before returning to a shallow and maddeningly slow pace. Gleaming swallowed hard and gave up holding her own leg out of the way. Instead, she slipped her hoof behind his rump and pressed him home, until his flared tip kissed the barrier of her cervix.

“...o-oh...b-big brother...”

“Big brother best friend forever,” Dusk exhaled, picking up the pace and filling the room with the rhythmic noises of their lovemaking. Gleaming’s fantasy stallion had gone away. Now there was only her ‘big’ brother, carrying her away on a wave of ecstasy she’d never before allowed herself to know.

“Y-you gotta...sto...stoahh...a-ahh...”

“N-nope,” Dusk replied through a series of grunts. Gradually his thrusting took him over her back, and he rolled her body until her chin and stomach were flat against the mattress. He lifted her rump and mounted her properly from behind, gripping her hips for support. From his new position, Dusk reveled in the clear view down his sister’s lithe back, all the way to her slender white neck; her tail lifted in the manner of mares being bred. His pace increased, and he could feel the welling, churning sensation within him, like a canon ready to fire his essence all the way to the moon.

“Nngh...” Dusk grunted, “...t-time for that f-first batch of cum in your tummy, sis...r-ready...?”

Gleaming’s face was pressed into the pillow. Her muffled voice came to him in a broken chorus. “...w-warm cum...i-in my tummy...b-big brother...”

Dusk’s pistoning hit a fever pitch. Gleaming bit down hard on the pillow, stuffing downy fluff into her mouth to keep from letting out a cry that was sure to embarrass the neighbors. Their civilization stripped away, the two rutted like beasts, joined in secret places neither sibling was meant to know. Passion welled, and for a critical moment, neither one of them cared about the consequences of their actions. Unfettered and unobstructed, Dusk enjoyed the welcoming caress of his sister’s velvety insides until his claiming abruptly ceased. With one great thrust, he mashed his tip hard against her cervix, pausing to instinctively hold himself and her in the deepest breeding position while his pulsing testicles pumped fertile seed through his body. Gritting his teeth hard, he fought in vain to stifle a whinny that broke from his lips - just as he began involuntarily ejaculating rope after sticky rope of his essence past the point of no return.

In seconds, the deed was done. His seed sown, Dusk flopped down upon his sister, scrunching her into the mattress. He wrapped his forelegs around her midsection and used his momentum to drag her back onto her side, where he could spoon her with his body and nuzzle her shoulder with his cheek. He tasted her ear again, still caught up in the feral show of dominance.

“…hahh…hahh…” He paused to collect his voice, “…y-you ok sis…?”

Gleaming didn’t reply. She was still trying to catch her breath. “..ah....ahh......hahh....” Her heart began to slow, and she lit her horn. Dusk felt an unseen force ruffle his short, stripy mane. Inside, she gripped his refractory erection and milked it for the rest of the creamy gift that lay inside.

Dusk nosed his way into her cerulean mane and placed a gentle kiss somewhere on her scalp. He didn’t need her words.

“I love you too, sis.”

“...needta...getup...” Gleaming muttered. Dusk reached out his hoof and began to massage the spike of tension in her shoulders back into a warm, dull, relaxing fog.

“Shhhh. Sleep with me.” He smiled and pumped into her absently gripping walls once, just for good measure. “No being a guard today. I’ll leave this here, deep inside you, so you can play with it again when you wake up.” His voice muffled as he buried his face in her familiar scent. “…then you can be mine again.”

Gleaming Shield, secured by sheets, her brother’s grasp, and the impalement inside her, couldn’t remember the last time she felt so...delicious. Her eyes closed, and she drifted back to snoring with a somber smile.

Outside, the world continued.
