In a world of soot-streaked rubble, where deep, jagged gashes from the earth vomited forth ichor and brimstone from the depths of Tartarus, the mightiest heroine in all Equestria raised her spear to the heavens. Bellowing a guttural, infernal howl, she caught a bloody spiked cestus in the glow of her unicorn magic and slipped it over her foreleg, trampling the desiccated corpse of the changeling who held it in the lock of its jaws. Armed only with her wits, her pride, and two worn melee weapons, she charged three-legged up a volcanic hill that had erupted out of nowhere from flat ground in time with an ominous repeating chorus of ’rectus dominus’. Marred with dirt and sweat, her ears clogged with the cries of victory and perdition alike, she vaulted for the summit, her blade held high, ready to plunge it into the yielding heartflesh of...
...a glass of orange juice.
Gleaming Shield snorted and shook her head, pulling roughly away from the color of harvest sunrise that had taken over her vision. Disoriented, she swiped at the offending swatch of orange until her ears carried a satisfying shatter to her brain, signaling that her foe had been vanquished. Mollified, she grinned a mindless, silly grin that persisted until another enemy slammed hard into her from behind.
Despite the force of the blow, she was not propelled forward. Confused, Gleaming blinked hard and drew the back of her hoof over her eyes, dismissing the sands of sleep from her vision until her focus came upon a clean, well-kept ceiling...and the purple face of a stallion, looking down at her with a certain bemused inquisitiveness curling about one raised eyebrow.
“Good job sis,” Dusk Shine held his foreleg up in a proper military salute. “You may have sacrificed yourself by the noble tipping of your own chair, but you sure showed that...juice golem what for!”
Gleaming’s brow narrowed. It occurred to her that she was now lying flat on her back in the kitchen, being looked down on by her physically larger, yet developmentally younger little brother. She folded her forelegs and blew a shock of cerulean mane out of her face.
“And the shattering was...” She held the sentence sardonically, cueing him to finish it.
Dusk made a dramatic explosive gesture with his hooves. “Smash. Your foe bled out his orange lifesblood all over the clean, linoleum field of battle. Mom will extoll your virtues in song throughout the land for generations to come. Or she’ll just yell at you.”
Gleaming could feel her cheeks heating up. She rolled her eyes, puffing out her cheeks in a pout, “Knock it off and go get the dustpan and the towels.”
Dusk moved off, but Gleaming watched as his swishing, raspberry striped violet tail sauntered over to the refrigerator instead. With a few simple swipes of his magic, the door opened, favored him with a tall glass bottle of milk, and closed again. The drink levitated up to his lips, and he enjoyed a long draw from it, the muscles of his throat visibly delivering the cool, refreshing liquid to his stomach. He spoke without looking back.
“Me? You made the mess. Your horn still works, doesn’t it?”
With a grunt, Gleaming Shield rolled out of the prone position on her back, planted her hoofs on the floor with a slight clack, and pushed herself up. Foregoing magic, she merely tilted the chair back into place with her hooves and paused to admire the fantastic mess of sticky juice and glass shards that was lying in an afternoon sunbeam from a nearby window.
“Because it’s your fault,” Gleaming snorted. “The glass broke because I’m exhausted, which happened because you interrupted my sleep.” She eclipsed the hold on the milk jug with the encapsulating glow of her own sapphire magic and yanked it away from Dusk before he could chug any more of it; succeeding mostly due to the element of surprise. The bottle came to rest on the ovoid table in the middle of the white kitchen before she added-
“And don’t drink right from the bottle. Mom told you not to do that I don’t know how many times. It’s disgusting.”
Dusk’s grin was infuriatingly mirthful, but he retrieved the requested items from the countertop that snaked around three walls of the room, stepped over to the mess, and saw to the chore of cleaning. “Alright, alright,” He chuckled. “But considering your morning, I don’t think you can complain much about drinking from the milk jug after me.”
Gleaming’s thirst outweighed her commitment to her point. She put power into her horn again, brought the bottle to her own lips and took a swig of it, sighing heavily as the cool liquid soothed the scratch in her throat. She fell silent after that - the only sounds in the room her little brother at his toil. Softly she placed a hoof on the trim tightness of her tummy and gazed down at the pure snowy fields of her coat, which were almost camouflaged in the blinding whiteness of the kitchen.
“...did we really just...?” She managed, her voice just above a whisper.
On his way to the wastebasket, Dusk reached down and favored his sister with a tiny peck on the cheek. “Sure did!” He sang as he trotted by, “And you were great, Sis!”
Whistling a merry tune, Dusk Shine did away with the offending shards of glass and replaced the cleaning implements. With little thought he ensorcelled a breadbox in a corner of the sky blue counter backsplash and drew forth a pair of fresh raisin bagels, setting them on a pair of elegant bone china plates that were much too nice for a light breakfast.
“Hey, you hungry?” Dusk smiled.
The lack of response drew Dusk’s attention. In the middle of the pure white room, his not-so-pure white sister was sitting with her forelegs splattered on the table, her chin resting atop them and her ears down like a wilted flower. Her eyes were lidded, and entirely too much of her attention was being taken up by a bowl of fruit in the center of the table. The ripe, stark spectrum of the fruit stood out in the relative ghostliness of the room, and each hue reflected in her cyan eyes such that if he didn’t know any better, he might have thought her hypnotized by the power of citrus.
Gleaming heard a clacking sound on the tile floor, followed by the sensation of a hoof stroking her shoulder.
“Hey,” Dusk began working his hoof in a circular pattern between Gleaming’s shoulder blades, “What’s up? You’ve gotta be hungry by now.”
Gleaming’s ear flicked under a wisp of errant breath from her brother. She kept her droll expression fixed on the bowl of fruit. “We should...talk about what happened. Earlier.”
“Yeah?” Dusk grinned, the pressure from his hoof constant.
“Yeah,” Gleaming huffed. “Dusk...I’m in heat. You came inside me.” She made a face, “I don’t really have to give you the birds and the bees talk at your age, do I?”
Dusk didn’t reply. Dipping his head down to the table, he wormed the tip of his muzzle into his sister’s locks and took a deep, audible breath from the unkempt jungle that pooled at her shoulders.
“C-cut that out--” Gleaming squirmed in a vain attempt to mash herself even further down into the table, the only route of egress for her upper body. “I haven’t taken a shower. I probably smell.”
“Mmmhmm,” The sound oozed out of Dusk like syrup over buttermilk pancakes as he drew another deep breath. “You sure do. I said it before - all our civility, and yet a stallion like me can still smell it on you like warm apple pie.”
“N-not that smell,” Gleaming pouted, worming ineffectually away, “I mean I probably...you know...stink. Sweat and all that.”
Dusk couldn’t suppress a giggle. He slipped behind his smaller elder sister and began to favor her wiry, tense shoulders with a proper massage. “You’d better get over smelling funny if you want to be a guard. You’re gonna be running around in hot armor all the time and I doubt they’ll let you shower whenever you want.” He drew in close to her ear and dropped his voice to a whisper, bathing her there in hot breath, “I’m not convinced it even suits you to be a guard, really. But what do I know?”
Before Gleaming could respond, Dusk levitated the plates of bagels over and sat them on the table. “You need to eat something,” He insisted. “It’s one thing for a guard to sleep in too long, but another not to get proper nutrition.”
Gleaming closed her eyes and allowed the circular motions on her back to soothe her insistent tenseness down into a buttery fluff, but she had yet to complain her last. “I-it’s your fault I slept in...”
“Ohhh no,” Dusk chided, working his sister’s back with as much gusto as he put into his speech, “You can’t pin that entirely on me, Sis. It takes two ponies to tango.”
The yin of Gleaming’s voice softened for every yang that her brother’s intensified. “I...told you no...”
“Mmhm,” Dusk hummed out his response through vibrating lips. He ducked down and touched the tip of his broad, equine tongue to the nape of Gleaming’s neck, until he could feel the slightly elevated pulsing of her jugular under his wet, protruding muscle. He ran it up, tracing her vein until he encountered her cheek, planted a kiss there, and worked his way up to her ear, where his voice dropped to a whisper again-
“But you didn’t mean no. You don’t even know yourself, Sis. But I do. You’ve spent way too long talking yourself out of what you really want out of life, in the name of responsibilty.” He let another breath wash over the wriggling flap of earflesh before him, “And it’s brought you here - three days away from a life of continual denial. I can’t possibly, in good conscience, let you make a decision like that without providing you with enough data to analyze. You know how I like having data to analyze.”
A barely audible whimper escaped Gleaming’s lips before she could swallow it down. Her ears wilted again - the right one splaying over her brother’s muzzle like a lily petal. “It’s not...that I meant no, it’s just...I said...and you said...” Her words became thick hunks of slag, clogging up the pathways of neurons between her brain and her lips. “...you’re my...we’re not supposed to...”
“Hungry?”
The jarring question threw Gleaming off of the narrow portion of her mental balance beam she’d managed to grasp. She blinked several times, not even realizing how long a ripe banana had been floating before her eyes. She studied the rather fat specimen of long, curved fruit as it hovered before her in a soft, transparent raspberry cocoon.
Gleaming’s stomach rumbled. Dusk let out another glittery chuckle, and the banana began to sway.
“You are getting sleeeeeeepy-” Dusk exaggerated his tone, “You will submit to the Tropical Imperium...looooook into my peeeeel....”
Gleaming allowed a jet of amusement to sputter its way out from the side of her mouth like the backfiring of an engine, covering it up quickly with a sour face. “G-geez, knock if off Dusk...”
Dusk’s hooves slipped down to his sister’s waist, just as his head came to rest between her ears. “You laughed.”
“I did not!”
“You totally did.”
Gleaming went cross-eyed trying to keep the banana in focus as it filled her field of vision. At length, the cool, smooth peel nuzzled her cheek, and Gleaming was left with nothing but a blurry double-image of it.
“I’m dirty too,” Dusk sang. “Let’s take a shower together.”
“What?” Gleaming’s ears perked up in alert, “No! We haven’t done that since I was four and mom was worried you’d pee in the tub or something!”
The banana kept moving, “What, you think I’m gonna pee in the tub?”
Frazzled by her brother’s annoyingly sharp wit, Gleaming rumbled, “Wha-no! Just...you can’t be serious, we’re too old to take baths together.” Her stomach growled again, “I’m gonna eat something, and then I’m going to take a shower. After that, you can go.”
Dusk snerked, dusting his words with playful sarcasm. “What a kind big sister best friend forever you are!”
Gleaming made to sit up, but found that she could not do so. In years past it would have been a pittance to lift her little brother up and move him around, but her growth spurts had ceased long before his. It was a point of self-conscious brooding whenever she looked in the mirror, wondering if a proper guard helmet would even fit her - but the idea that she couldn’t manipulate him so easily anymore stuck to her thoughts like peanut butter on the roof of her mouth. She muttered something under her breath. She was sure her brother was close enough to hear it, but he perked his ears and made a show of leaning closer anyway.
“What was that, dear sister?”
“...let me up,” Gleaming muttered.
Dusk pinched Gleaming’s ear between his lips and gave it a single, short yank, before pressing his muzzle up to it again, his voice like honey-
“What do you say...?”
“...please,” Gleaming swallowed.
Dusk’s tongue traced the entire perimeter of Gleaming’s ear, pressing against every escape route it sought and rendering them all ineffective. “Take a shower with me.”
“...n-no...” Gleaming muttered again, her voice muffled by the mashing of her lips into her hooves on the table. Dusk captured her ear again - not that it could go anywhere anyway - and yanked harder this time before returning to her neck. He pressed a deep kiss into the thin, sensitive coat of her nape, while the banana began prodding gently at her lips.
“Open,” Dusk cooed, “Open for your breakfast, Sis....”
Gleaming felt the heat on her cheeks. It might have gone volcanic if not for the mitigating coolness of her brother. His hooves found purchase at her hip bones and his tongue found a sweet spot just at the hinge of her jaw. Asserting its dominance, the humble piece of unpeeled fruit wormed its tapered form past Gleaming’s lips and spread her cheeks, until it teased lightly at her uvula. Gleaming coughed.
“Shhhh,” Dusk probed against the grain of Gleaming’s mane, whispering into it, “I know you can take it deeper than this. Give me a nice show and you might get to have something better.”
Gleaming closed her eyes. In her mouth, the ensorcelled banana began to slide back and forth, drawing flavorlessly across her taste buds. She cupped it with her tongue, matching its shape, and formed her lips around it, producing a number of satisfying suckling noises as it pulled back and slowly invaded her again.
On the cusp of a deep giggle, Dusk Shine mussed his elder sister’s mane with his muzzle, traveling upwards until the tip of his snout touched the rounded, elegant keratin of Gleaming’s horn.
“You know Sis,” He oozed, “I’ve done the research, and because it’s me, you know my facts are accurate - only six point seven five percent of all adult unicorns in Equestria report having a horn as...sensitive as yours--” He touched his tongue to the snowy spire and gave it one quick lick, “--and it’s absolutely adorable.”
“Nghh...” Gleaming felt a thickness in her throat other than the banana. She managed to swallow through it, but her teeth came down on the firm peel, momentarily arresting the back and forth movement of her tropical suitor.
“Tsk,” Dusk paused in his machinations, “Treat it with respect...like the real thing...” Trailing off, he placed a hoof on the pack of Gleaming’s head and pushed firmly, encouraging her to dip her head down enough to provide him with a better vantage to his goal. Licking his lips, Dusk touched them to the rounded tip of Gleaming’s horn and made a tight seal, pushing slowly down - allowing the taper of the horn to pry him open as he went.
Gleaming felt a shiver run straight up her spine and rattle between her ears, threatening to unhinge her tenuous hold on temperance. Her tongue waltzed with the banana, lathering it with appreciation just for its presence inside her as it pumped in and out of her maw.
“That’s right Sis,” Dusk pulled away from his spiraled meal long enough to whisper. Gleaming felt a stiff presence at the small of her back, which her brother unnecessarily elaborated upon, “Feel what you’re doing to your big brother? Everypony calls me an egghead - my best friends swear I’m gonna marry an encyclopedia set someday. Look what you can bring out in me though.”
Gleaming Shield sent an instinctive wave down her back, pinning her brother’s erection between his fur and hers. She waited patiently for the banana to slip from her lips before taking in a sharp breath of air.
“Big brother indeed...” She commented sarcastically.
“We talked about that already,” Dusk chuckled, “I’m bigger than you. That makes me the big brother, right?” To punctuate his assertion, Dusk sent his tongue on a slow, deep expedition upwards from the thick base of Gleaming’s horn. When he conquered her arctic summit again, he wrapped his lips around her and proceeded to melt her snow-capped mountain. He could feel her horn trying to push in further, but he kept control of the situation, refusing to take her any deeper and even pulling away again to speak.
“You know, with your extra sensitivity up here, you sort of know what it’s like for a stallion,” Dusk grinned, stroking the aroused horn with his hoof just to make his sister squirm, “Want some more?”
Gleaming, her face now practically on fire, buried it in her hooves and shook her head. “...uh-uh.”
“I think you’re lyiiiiiing~” Dusk licked the horn again, savoring it like a popsicle. “What do you say?”
Gleaming didn’t even realize she was choking herself in the grasp of her own hooves. When she came up for air Dusk drew his tongue over her spiral again, and what was supposed to be simple oxygen replenishment turned instead into an arching of her neck as she let out an unplanned moan. Dusk’s ears twitched as he picked up a gratifying whisper on the cusp of his sister’s feral whine-
“...m-more please, big b-brother...”
Dusk traced the luscious curve of Gleaming’s right hip with one hoof. “See? You wanted to ask for that, but you were embarrassed,” He offered gently. “That’s what I’m talking about. Ever since you got this ‘guard’ thing in your head, you’ve been denying your nature. Now, how about you just let big brother make your wish my command, hmm?”
Dusk didn’t give his elder sister time to respond. With her head still arched back to a perfect angle, he wrapped the permanent hardness atop her head in his slippery embrace and took it down, down...until he was able to plant a kiss somewhere in the forest of her bedhead mane. He pulled back, purposefully loosening and tightening his grip to elicit smacking noises, and began to fellate his sister until a sapphire glow flared to life under his lips.
“Nngh...hahh...”
Gleaming squirmed. Dusk was not the largest young stallion, but she was on the smaller side of mares. Even with their age difference, it was little effort for ‘big’ brother to keep ‘little’ sister in place. With Gleaming pinned, Dusk continued to pluck the rest of her conscious thoughts away and replace them with the pulsing miasma of unbridled lust.
Dusk kept the maddeningly slow, teasing rhythm up until the only sounds in the room were the squishing of his lips, the soft moans of his sister, and the donging of the grandfather clock in the hallway as it sounded half past two in the afternoon.
“Mmm,” Dusk licked his lips, finally ceasing his assault to enjoy a nice stretch of his neck, “Funny, I didn’t know that magic could taste different from time to time. Yours is more like wintergreen this time around.” He stroked Gleaming’s shoulder, enjoying the feel of the minute tremors brought on by the opening fissures in her reason. “Shame you can’t get off just from that the way a stallion can, huh. But it’s not like there aren’t other ways…”
Gleaming felt nearly twice again the weight of her own body suddenly leave her shoulders, along with the hardness probing at the small of her back. She sighed, barely hiding her disappointment at the sudden freedom, but sat up at the table, working a few new kinks out of her shoulders, forelegs, and neck.
“So,” Dusk’s voice came to her unseen, as if through telepathy, “Ready for that shower?”
Gleaming closed her eyes and tousled her mane with a great sweep of her hoof. The movement felt clumsy, but she had seen models pull it off before, and she had a strange desire to show it off to him now. “That’s too much,” She huffed, “Besides, you don’t really want to take a shower, hornycorn.”
Dusk clucked his tongue. Gleaming blinked, and when she opened her eyes again, she found him sitting on one of the chairs, shaking his head as if to pity her. His hind legs were lewdly spread, and between them a great, curved, deep violet spire twitched nearly half the way up to his chest. “You know,” He commented, “you sink back into denial so fast it could be called a psychosis.”
Gleaming blew a wayward bang out of her eyes, but the weight of the sweat-matted bramble sent it swinging back into her face again. She narrowed her gaze as if to give her own hair a dressing down for its insolence, but the distracting image of her brother’s proud, tall erection persisted beyond. She turned away sharply.
“It’s not like that,” Gleaming complained, levitating an orange and inspecting it. “It’s just...you know. I’m going in for guard training. I have to maintain discipline.”
Dusk snorted. “There’s a difference between discipline and denial. I still hit my books hard nearly every day--” He reached out to openly stroke himself, “--but I still have time for this. I’d never be able to keep my concentration if I didn’t take care of my needs. But you - you seem to think you can just ignore them and they’ll go away. That’s a recipe for disaster, you know.”
It was Gleaming’s turn to snort. “You read too many novels and not enough textbooks. You’re being too dramatic.”
“Am I?” Dusk sat back. He touched his foreskin and let out a purposefully audible rumble as he pinned it against his stomach, only to let it snap back out again under its own inertia. “You know, I’m an observant pony. In the time it took you to say that, your eyes darted over here three times.”
Gleaming blushed, her eyes going wide, but she kept them stoically on the floating orange. “I...I did not.”
Gleaming noticed the raspberry glow of her brother’s horn spawning to life out of the corner of her eye. An instant later, one of the two fresh raisin bagels took to the air in front of the orange, and playfully bopped her right on the tip of her snout.
“You’re still hungry right?” Dusk queried, the bagel hanging tentatively in the air. She was about to shove the offending baked good out of her way, but she froze up at the sensation of an electric tingle that suddenly appeared at her rump, just under her tail.
“Wh...what did you...?”
“Not a thing Sis,” Dusk insisted as the banana began to slowly pierce Gleaming’s flower. “I just asked you if you were hungry - again. But you’re in training now,” he said nonchalantly, still petting himself with one hoof, “So I guess nothing gets past your guard, huh?”
Gleaming felt her shoulders slump. She gritted her teeth, locking her knees into a proud stance against the invasion of her already damp blossom. Dusk had managed to get the banana all the way around her and stab her with it, just because of token distractions. It was infuriating...but it was also enticing, and the siren song of lust began to rise in her brain again.
“Psst,” Dusk whispered, “Look over here.”
Gleaming’s tongue was just about to make contact with the crust of the bagel when it began to float away. She followed it through the air, charmed like a cobra by its silent gyrations, until the ring of bread came to rest against the broad tip of Dusk’s erection. Dusk held his sister’s gaze, grinning coyly until the banana fled from her depths and floated over to him. It began to paint her own lubrication over his length and the bagel hole; properly lubricated, his tip began to thread itself through the baked good. Gleaming watched as a bead of Dusk’s clear pre-seed appeared from the middle of the bagel, followed by the rising pride of his girth until the bread began to crack slightly from the strain of being stretched. The bagel came to rest just atop Dusk’s medial ring - unable to travel any further lest it be rent asunder by the powerful masculinity that pierced it.
Gleaming was staring, her mouth slightly ajar. The banana passed right before her eyes and floated patiently back under her slightly elevated tail, slipping back inside her without the slightest conscious restraint from the petals it pushed apart.
Dusk patted his thigh and repeated his question-
“Hungry Sis?”
Gleaming Shield felt the wayward fruit command her button again. Her ears pinned down to either side of her skull and she let out a whimper as she moved to respond to her brother’s patting hoof.
By her next breath she was close enough to take in his musky scent. It ballooned her lungs, filling her with a lusty buoyancy that drew her to him as easily as if she were bouncing on a cloud. She rubbed her snout against the smooth surface of the bagel, and then ran her tongue around the groove of its fully involved hole, lapping up both her own juices and his pre-ejaculate. Dusk brought his hoof down and ran it through Gleaming’s unkempt mane.
“Yeah...” he whispered, working the banana in circular motions with his magic, “This is where you really want to be, right? What you won’t admit to anybody...even to yourself.” He took up a dollop from the new bead upon his tip and painted Gleaming’s snout with it. “It’s just you and me here now, Sis...don’t be shy...”
Gleaming could feel the heat on her face that her coat color could not hide as well as her brother’s. She followed Dusk’s hoof upwards until she met his eyes again. Trapped there, she pressed her lips to the flesh of the bagel, favoring it with a tender kiss until she broke its crust with her blunt equine teeth, drawing a hunk of the dark bread into herself as though she were trying to suck the juices from a ripe pomegranate. Dusk continued to stroke her mane affectionately, scratching her behind the ears.
“I knew you were hungry,” Dusk smiled wanly. “Go on. Get your fill. And then we’re going to take a shower together.” His voice dropped to a whisper, “But don’t hold back, Gleamy. Take what you really want.”
Gleaming Shield worked her way into the raisin bagel that encircled her brother’s penis, gnawing an uneven pattern all around it. She paused every few bites to flutter her tongue over his tip or lap at his base, collecting the mixture of his juices and hers to add some spice to her meal. On the third trip around, the bagel finally failed and dropped away. Ignoring it, Gleaming grunted and devoured her brother’s flared head, enveloping it with the same welcoming squeeze her nether walls used to invite the fruit into her weeping flower. She felt the satisfying twitch of his arousal as he fed her another few drops of his preparatory ooze.
“Nnngh...” Dusk hissed through his teeth, “You’re a natural with your tongue, Sis. Not a whole lot of mares can say that - I should know, because I’ve examined the research data.” He stroked the side of her head and neck, letting her control the pace of her own bobbing lips. Despite his control over the situation, Dusk bit his lip in gleeful anticipation every time his plum-colored girth vanished inside her.
“W-wanna know what you look like?” Dusk continued without waiting for an answer. “You fit perfectly down there, a-at your size...nng...all curled up with this angelic look on your face...” He brushed her bangs out of the way to admire her subtle expression, “You’re at peace. There’s no ‘conquering heroine’ in your mind. You just ended up t-telling yourself that’s what you want out of life...t-to live up to the standards others set for you. Nnng...y-you’re in worship down there, and you’re n-not ashamed to admit to it.”
Gleaming offered no response beyond the swaying of her tail and the muttering vibrations that escaped her throat. In her mind the kitchen was gone - replaced by golden Hyborean halls where her sandaled hooves held court. Her armor still adorning her breast, she knelt before the loins of some mighty stallion, who had fought and bled with her across ages of relentless battle. She was proud, powerful; an inspiration to all the ponies she protected from harm. But she was also a mare. Also had needs.
And only the greatest of heroes were good enough to sate them.
Gripping the banana so tightly that Dusk nearly lost control of it, Gleaming expressed how her image of herself clashed with his by suddenly swallowing him to the hilt. The impact of her snout against the thick tuft of tummy fur that presided over his stallionhood sent her into a flurry of internal motion, her tongue assaulting every engorged vein with a tantalizing onslaught of teasing probes and tracing licks.
Dusk let out a sharp breath, his back arching slightly, “Erg...h-hey Gleamy...n-not so fast...”
Gleaming Shield did not relent. Since the very moment her little brother had drawn back the cloak of sleep, he had been in control. It was her turn to assert herself as the elder sibling.
Dusk bit his lip and let out a gasp. He sat back, pushing his erection farther into its wet home as he rolled his eyes to the ceiling. He lost control of the banana, which slipped out of its target and landed with a muffled, yet still audible thump on the floor. “Ngh...Gleamy...”
Encouraged by her success in disarming her brother, Gleaming brought a hoof up to caress the tight flesh of Dusk’s, fuzzy scrotum - the testicles beneath churning noticeably in the constricted space. She knew the signs. Knew he was getting close.
“I kn-know...” Dusk muttered, his hoof coming down weakly on Gleaming’s head, “...know wh-what you’re t-trying to do, Sis...gonna drain me right now a-and go get that hot shower all to y-yourself...” Gleaming’s eyes widened, and Dusk laughed lightly. “Uh-huh...I’m a sh-sharp cookie, you know...”
Her plan discovered, Gleaming went with Plan B. Increasing her pace even further, she bobbed furiously on her brother’s tall erection, taking it in as far as her gag reflex would allow. Her sexual game played into a corner, she sought the simple expedient of overwhelming Dusk and pushing him over the edge.
The touch of Dusk’s hoof became firmer on Gleaming’s head. He could feel his desire to release coursing through him, making its demands of him...but he held it in, kept it under control, and took to whispering-
“Give up, Gleamy,” He cooed, stroking her mane now, “Come on, give up. Just slow down and sit back. I’m not gonna force you to stop. You’re gonna do it for me, right?” He let out a breath again, trying not to show how close he was, “Imagine how the water is gonna feel all over your back while you’re bent over the tub, accepting your nice big brother, hmm?”
Gleaming Shield let out an unintentional whimper. Dusk slid his hoof down and tapped her cheek.
“Come on...” He encouraged, “Up...off...you’re gonna have to be patient if you want it the right way...”
Gleaming’s eyes met her brother’s once again. His knowing grin quelled her as effectively as the organ in her mouth. Her movements slowed, and she allowed him to pull her back until his throbbing, blunted head was back to staring her in the face.
“H-hold still...” Dusk grunted.
Charmed by the masculinity before her, Gleaming’s mind filled with the images her brother had instilled, until her reverie was broken by a raspberry glow of magic. It surrounded his girth, taking over for her, and Dusk let out another deep grunt.
“Huh?” Gleaming blinked, “Wai--”
The first hot rope of seed splashed against her cheeks so suddenly it cut her words off. She jolted with surprise, but Dusk placed his hoof behind her head and pushed her face in closer.
“Nnngh...j-just take it...” Dusk muttered, “Y-you need a good...face painting...trying to outdo big brother like that...”
Gleaming closed her eyes again. She might have argued the trick her brother had played on her, but the next hot splash across her forehead drew up a contented sigh from somewhere deep inside. She turned her face to it, warming herself by the squirting seed as though in the glow of the sun on a pleasant afternoon. It felt liberating to give herself over to such a debased act, and she reveled in it, her world reducing only to herself and the trembling release of her own kin. She tried to envision her Adonis once again, but the only face that revealed itself from the desert throne above her was that of her little brother, who was by no means quite so little anymore.
“Gleamy...” His voice leaked honey into her ears even as the tip of his hoof gently painted her lips with one remaining bulb of of his seed. “You’re a mess...”
Gleaming licked her lips, suckling lightly on the tip of the violet hoof. “...uh-huh...”
“What would your trainers say about you, if they saw you like this?” Dusk went on, watching as his sister automatically touched her lips back to his flared head, just to claim what was left there. “You’re hardly presentable. I think you need a bath.”
“...uh-huh...”
Dusk affectionately patted Gleaming, enjoying the slight pout on her puffed up cheeks. “Wanted it inside you, didn’t you.”
Gleaming looked away. Coming back to herself slightly, she blushed. “...I thought that’s why you wanted me to stop...”
“Nah,” Dusk continued to pat his sister like a puppy, “I just wanted to see your adorable face with my seed all over it. You’re forgetting that you’re in heat, Sis.” He couldn’t help revisiting his clinical explanation from the morning, “It’s like I told you before - it doesn’t matter who the stallion is. Nature is nature. And you smell lovely when you’re in heat.”
Gleaming felt the fire on her cheeks turn volcanic. Out of the corner of her eye, she noticed her brother’s lively stallionhood already brimming with new life. Dusk caught the glance and tilted his head, favoring her with an wry look.
“See? I’m not empty yet. Not by a longshot.” He rose to his hooves, making sure to give her a fine view of the bouncing erection beneath him. “It’s time for your bath, Sis,” He sang. “Come along.”
Dusk left the room with a delectable swagger in his hips. His tail swished in a perfect arc, providing his sister with a deliberately intermittent view of his heavy, dangling testicles.
Gleaming gritted her teeth in annoyance, but she fell in with him all the same.
By the time the two ponies made it down the empty hall, they had changed marching order. Gleaming entered the sterile bathroom first, with her brother in hot pursuit. Dusk filled the doorway, pausing there on purpose just to demonstrate the inaccessibility of the room’s only exit. When he did finally cross the threshold, he left the door slightly ajar.
Gleaming made a face, “Aren’t you going to close the door?”
Dusk grinned. “Why? Afraid somebody’s gonna hear you crying out, Sis?”
“That...that’s not what I...” Frazzled by the smug comment, Gleaming spun towards the ample sink area and stared at herself in the large, well-lit mirror mounted to the wall. The coat hairs of her face were turned up in tracks matching the pattern of the dried semen that irrigated her, while her frizzy, bedhead mane made it look as though she had been sleeping for days. Her cyan eyes were sharp, but there was a certain starry gleam in them - as if she were looking upon the face of a friend, and seeing there the signs of girlish infatuation.
Dusk was suddenly there behind her, his hooves back to massaging her shoulders. “Tsk. Looking like that at three in the afternoon,” He scolded. “What a slut mother raised.”
Gleaming made as if to protest, but the large hooves that worked her shoulders dulled her edge, encouraging her instead to lid her eyes by half and stare dreamily into the mirror.
“I didn’t forget how much you love my massages,” Dusk said softly. “I was barely out of magic kindergarten, lying on your back in your room, rubbing you with my little hooves...you remember it, don’t you?”
“Mmhmm...” Gleaming murmured, guided easily back to the memory.
“That was pretty innocent back then, wasn’t it?” Dusk pondered. “It took a couple years before I started humping your back. Come to think of it, you yelled at me whenever I tried that.”
Gleaming knitted her brows, a lost look on her face. Dusk drew closer, washing her neck with his breath.
“A good big sister would let her little brother explore more. Would help him learn.” His hooves slipped down her back, kneading her coat on the trip down her spine. “A good big sister would offer her body up to the experience. Don’t you think?”
“...offer m-my body...” Gleaming cooed. She could feel herself sinking, her light dimming. It was the same transformation her brain went through whenever she lay alone at night in her bed, shamelessly rubbing her flower. Now, as then, writhing tendrils of lust coiled around her thoughts. Placing her hooves on the sink for support, she parted her hind legs, raising her tail for her brother’s wandering hooves as though she expected them to plunge into her.
“Uh-uh,” Dusk shook his head. “Not here. Not yet. But you know,” He began to stroke under her tail, finding the blooming petals with ease, “There’s a term for ponies like you. Oversensitive horns. Weak against deep kisses. Easy to overwhelm with a few good button pushes, until you sink so deeply into your depravity that you’d happily give yourself to me, when you know for a fact that I’m not gonna put a condom on. They call ponies like you ‘perverts’. You know why you’re a little pervert? Because you love every minute of it.”
Gleaming’s heart skipped a beat. “N-no, Dusk..we talked about this before...we should be using protection...”
Dusk shook his head. He reached around to stroke Gleaming’s stomach. “Nope...I think you need another nice warm batch of cum in your tummy. We’ve gotta make sure you take, after all.”
Gleaming whimpered. “....b-but...”
“Shhh,” Dusk gently nipped his sister’s ear. “You know you want big brother’s cum in your tummy again, Sis. Don’t fight it. Don’t be ashamed of what you want.”
Gleaming was panting now. “...c-cum in my tummy...”
“That’s right, good girl,” Dusk smiled. He began to grind his penis into the small of her tiny back. “You really wanted that humping way back when, didn’t you. You were just being prim and proper.”
“...I...I wanted it...”
“Yes you did,” Dusk agreed. “Don’t you think it’s kind of ironic how we don’t wear clothes, yet for some reason shower time is so private to us? It’s something of a social abnormality, don’t you think? As if there’s some distinction in being naked and wet.” His hoof began to draw squishing sounds from beneath her, “Remember when you used to throw me out of here if I ever peeped?”
“...yeah...”
“Well, now you’re going to make it up to me. Be a good little sister and get in the tub. Brother’s going to peep on you. Watch you bathe. And you’re going to let me.”
“Y-yes...” Gleaming fluttered her eyelids. Nothing was in focus anymore, and she turned deeper into the room, away from the escape of the door, her attention on the large, tiled tub and showerhead.
“Even when you were shooing me away,” Dusk continued his oratory, “You wanted to let me peep. Wanted to let me in with you even, when I was old enough. Wanted to let nature take its course. Well, I’m your big brother now. No more shooing me away.”
“Big brother...” Infected by the precision application of her brother’s words, Gleaming stumbled over the lip of the creamy beige bathtub and planted her hooves into the far wall to keep from toppling over. With no thought for preparation, she lit her horn and turned the familiar knobs she didn’t need to look at until a stream of icy cold water assaulted the most sensitive areas of her spine.
“Nngkk-!”
Dusk had to stifle a giggle. “I love how eager you are, Gleamy.” He closed his eyes and activated his own sorcery. In his mind, he could see the entire delivery system for the water supply. He enchanted the flow, altering it from an icy sting to a simmering warmth faster than the plumbing could. Gleaming arched her back, sticking out her rump to maximize the soothing contact of the spray.
“...nnn...”
“You’re welcome,” Dusk smiled. He stood back and feasted his eyes on the image of his soaking sister, leaning on the wall with her rump pointed at him. The stalk of her tail was pointed straight up, but the hair was weighed down with water, leaving her with a cascade of cerulean locks framing both her flanks.
“Brother’s watching...” Dusk sent out the verbal reminder, and then quieted.
Gleaming shield turned to face the showerhead. Her profile now in view, she turned her face up to the flow, her eyes closed in worship as the water began to work at the semen-tracks on her face. She brought her hooves up and ran them through either side of her soggy mane, sorting the strands down her back. She stood tall on her hind legs, her entire body curved towards the water as it trickled down her collarbone and flattened the tuft of fur at her chest.
Dusk watched silently as Gleaming summoned her magic. The shampoo bottle ran in a solid pink trail from a few inches above her head, until she was working her locks into a great bubbly fluff. She replaced it with the body wash, upturning the new bottle and letting it leak out a long, viscous trail from the back of her neck to her tailbase. Setting the second bottle aside, she pushed her head completely under the water, rubbing her hooves through her soapy mane as flow engulfed her and began to turn the bubblegum pink liquid on her back into new sudsy lubrication.
Dusk sniffed the air. “Strawberry. I bet they don’t use stuff like that in the barracks much. It makes you feel like a mare,” He observed, “doesn’t it.”
Gleaming replied with little more than a high-pitched, excessively feminine whine. The sound was a subtle signal - one Dusk knew well.
“Mmhm, that’s the sound you make when you’re just about to rub yourself silly in here.” He moved to the lip of the tub and stepped over it, coming up behind his sister with no warning of his presence until she felt his hooves resting on the fleshy cheeks of her backside. He massaged the body wash in, slipping his hooves up the small of her back and down again as he worked the fragrance into her.
“Show me how much you want big brother to make you a mare,” Dusk cooed.
Gleaming pressed her hooves to the wall again, this time just under the showerhead. She stretched out, her head passing the flow until the water was beating down her neck, smoothing her mane to either side of it and down her shoulders. The movement pulled her slightly away from Dusk, but if gave him a perfect view of the tip of one of Gleaming’s hooves, which had fled from the wall and was worming between her hind legs from below. She parted her legs further, shamelessly displaying her marehood for her brother’s inspection as her hoof settled into a circular petting just over her engorged button.
“...ahh...”
Dusk treated himself to the show, stepping forward only long enough to rub his proud erection between the cleft of her rump to coat it in slippery bubbles. He stepped back again, and began to pet himself as well, stroking his length in time with her spinning movements.
For a time, they reveled in the throes of mutual masturbation. Each masculine grunt that alighted Gleaming’s ears put an extra arch in her hips. The one remaining hoof she had on the wall lost ground; her front end dipped with it, thrusting her rear further up and spilling her heavily matted tail over her new slope in her back. Her lips found the small, low-hanging mirror mounted under the showerhead. It fogged up easily and was of limited use, but she kissed the hazy reflection of herself in it anyway, making love to her brother’s lips by proxy.
Dusk felt his composure finally start to crack. His mind strayed back through the past week, to the time he had spent lamenting the loss of the sister he wasn’t sure he could get by without. He was clever and good at keeping up appearances, but the truth he had yet to admit to was a near-total inability to concentrate on his studies ever since she announced she would be living in the barracks. As bright as he was, even his vocabulary was insufficient to put the depth of their bond into words.
Dusk Shine could discern his sister’s moods and desires from cues so slight that even their parents couldn’t catch them all. He wanted her to be happy. But no matter the lip service she paid to it, he knew she was merely trotting the path set before her - convincing herself of a desire for some nebulous future in high-profile propriety.
He leaned back in, blushing deeply in his own right, and again ran his length between her slick cheeks. “It’s okay to want this, Gleamy,” He whispered, stroking her back affectionately. “It’s okay to love your brother in a deeper way.”
“Ngh...hahh...” Gleaming fought against the whinny in her throat, giving voice only in part to it. “...ahh...l-love...hahh...b-bit brothahh...”
Dusk’s smile was more genuine now. “I’m going in now Gleamy,” He placed his hooves properly on her hips and repositioned his tip to kiss gingerly at her soft, moisture-weakened walls. “Time for another batch of nice warm cum in your pretty pony pussy~”
“P-pony...pussnnngahh!”
Slowly impaled to the hilt, Gleaming found that her lips would no longer obey her commands. The wall clacked as she thrust her other hoof back against it for support. Every word she tried to produce was swept away on the river of her passion, replaced with the melodies that fueled the fires of her stallion mate.
“Oh...ohh Dusk...y...”
Honesty chipped away the cunning edge of Dusk’s smile. He took note of the extra syllable Gleaming added to his name, and the adoration in her voice that came with it. Buried deep inside her, his hips bucked - quickly he began to build his painfully throbbing organ into the rhythmic pounding that the scent of estrus demanded.
“Mom and dad could...b-be home at any minute,” Dusk sang softly. “I-it’s too late to stop now...too much risk they’d find us here and wonder why we’re coming out of the shower together. But you don’t really care, d-do you...”
“...uh-uh...”
Dusk kept pumping, “I-if anything it’d be a load off your mind, not having to hide how much you l-love this, anymore...”
“Mmhmm...”
“No condom, no protection,” Dusk hiked up his speed, his knees nearly buckling at the shocks of pleasure from each spasmodic grip of the walls all around him. “Just m-mare and stallion...j-just what nature wants from you...” He stroked her again with surprising lightness, given the savagery of his thrusts, “Y-you’re such a good mare...”
Gleaming no longer cared for her facade, “...ahh...hahh...g-good m-mare...o-oh Dusky...d-deeper...faster...”
Dusk accommodated all his sister’s requests. He felt the churning inside him reach a fever pitch; his testicles tightening with imminent release.
“...t-time for your seeding, little sis...” Dusk barely got the words out, “T-time to make your pony pussy happy...swell up your tummy...” He managed a chuckle as he felt his analytical nature forcing itself into the fray, “D-did you know...? Semen can live for seventy-two hours inside your womb...e-every time we do this, you get to carry around a p-piece of your brother wherever you go...and if we keep it up, you’ll never be without me...”
Gleaming slammed a hoof against the wall and let the uncivilized whinny that had developed in her throat fly. Orgasm took her, and the uncontrolled assault on her brother’s penis sent him hurtling towards the same fate.
Dusk reared back and rammed his sister hard, pushing her further against the wall. He held her there, all movement stopping as his instincts kept him in the deepest, best place for fertilization. He boiled over, and scorching trains of young, virile seed planted themselves deep in the snowy fields of the womb that was so biologically close to him.
He arched his neck and smiled dumbly at the active showerhead. Somewhere in the caverns of his mind, misfiring synapses made him think fondly upon dusty tome of decrepit lore he’d found in the archives two days ago. The book had been his inspiration for this entire day – between its covers he had found the proper spells to ensure healthy offspring from a very close genetic union. It had been intended for use only by royalty and high aristocracy to sate their desire for purity in their bloodlines, but the practice had fallen out of Equestria’s vernacular, and the marvelous tome had been forgotten.
Dusk vowed to bring it back. Starting right here, with the pony he loved more than any in life.
Rewarded by orgasm for their adherence to nature’s breeding program, both ponies sank to the bottom of the tub. Dusk slipped out of his sister, found a comfortable position to rest his back, and laid her head on his shoulder. He then lit his horn and manipulated the drain controls, switching the water flow as well, until the showerhead fell silent and the faucet filled the tub with comfortably warm, soothing, bubbly water.
There they lay, soaking themselves in the bathtub, their breaths slowing in perfect time. They were together, and in Gleaming’s vivid fantasies there was no longer a battle to be fought or an enemy to vanquish. She saw a blue, salty sea on a clear tropical day, with white sand and gentle breezes. Her ears twitched at the sound of ice clinking in an imaginary glass. She lay against her big, broad brother in a warm lagoon, her mane matted and mingling with his. She ran her hoof across his chest, drawing silly circles there, and giggled like an inebriated filly with the warmth of her afterglow.
“Shh,” Dusk cooed, planting a kiss on his sister’s forehead. “You’re a very good broodmare for big brother.” He reached down to stroke her tight tummy, “You’re going to be beautiful when you start to swell up with foals by me, and when you deliver, we’ll fill you up again and make ourselves a lovely family. Then we can be together forever. Big brother loves you very much.”
Gleaming’s eyes were closed, she giggled, the hero in her mind now firmly sporting the image of the colt she’d grown up with. “Mmhmm...love you too...”
Another sound came to both their ears. Gleaming Shield heard it as nothing but the thrum of her lover’s heart. Dusk recognized the din as hooffalls on a staircase.
“Dusk?” A familiar voice called from down the hall. “Gleaming? Kids? Are you here?”
Dusk smiled. Stroked Gleaming’s mane. Committed himself.
“...in here mom!”
