Hearth Warming's Eve

Author's Note

Merry Christmas, you depraved people!

Hearth Warming's Eve

Twilight staggered as she hit the ground quite a bit harder than she had intended, stumbling a few steps and then quickly straightening to walk as calmly as she could, playing it off. Her wings folded neatly to her sides, and she grit her teeth at the numb sensation on her forehooves from landing too hard. She was still not used to complicated flying techniques like landing, taking off, or flying in a straight line.

The summer house stood on the edge of a steep hill overlooking the ocean, with wide front windows affording a spectacular view of the beach and the waves. The entire building was built of strong wood farmed from the surrounding forest many, many generations earlier, and had been in the Sparkle family for hundreds of years. Renovations had kept it up-to-date, and the sheltered cove it resided in was private and rarely travelled.

The front door was already wide open, inviting, and Twilight stepped through it, wincing slightly at the burning in her wing.

Shining Armor and Cadance were already sitting at the table, sipping at mugs of coffee. Both of them looked up as she entered, chirping a happy ‘Hi Twilight!’ in stereo.

Twilight blinked repeatedly at the odd echo, and then gave a helpless smile. “You two practised that, didn’t you?”

Cadance giggled, and Shining Armor gave a guilty smile and a shrug of his shoulders.

Smiling, Twilight pushed the door closed behind her, reaching back to take off her saddlebags, giving a wince as she tugged the strap from around her right wing.

“Are you okay, Twily?” Shining Armor asked, concerned.

Twilight nodded. “Just my wing is a little sore is all. I think I flew a little too far.”

“Well you did insist on flying,” Cadance chimed in. “I told you you should have taken the carriage.”

“I don’t like feeling all… princess-y,” Twilight said, wrinkling her nose as she slipped her saddle bags off and placed them on the counter.

Cadance gave a warm smile at that, nodding her head. “I was like that at first, too. But you get used to it.”

“I don’t hesitate to use my position to get a little help,” Shining Armor admitted with a shrug of his shoulders and a sly smile.

Twilight shook her head, stalking over to the table, pulling a chair out for herself with a touch of magic. “You should both be ashamed of yourselves.”

Cadance just smiled, offering a mug to Twilight.

Twilight took the mug, lifting the teapot to pour some hot water into it. “So when are mom and dad due to arrive?” she asked, turning to her brother.

Shining Armor gave an uncomfortable shrug. “Well, they should have been here already, but most likely got tied up somewhere.”

“You mean that they’re off enjoying some privacy,” Cadance said with a candid smile, her expression leaving no doubt as to what she was implying.

Twilight looked back and forth between a very nervous Shining Armor and a smug Cadance. “What? Why would they be worried about privacy?”

“I love you, Twily, but you are so naive,” Shining Armor said with a shake of his head and a soft chuckle.

Cadance smiled as well, leaning over to ruffle Twilight’s mane good-naturedly. “You’ll understand soon enough, I’m sure.”

Twilight paused, frowning down at her mug. “You mean… intercourse?”

Shining Armor spluttered, and Cadance giggled, shaking her head. “Sex, Twilight. It’s sex.”

“J-just because you’re the alicorn of love doesn’t mean that everyone is so comfortable with… with intercourse,” Twilight stammered, her wings giving an unconscious flick and flutter.

“Well, I—” Cadance paused in her response as there was a knock at the door.

“I’ll get it,” Twilight said, stepping down off the chair and stalking towards the door, pulling it open. A pegasus royal guard stood at the door, panting faintly, a rivulet of sweat dripping down his form.

Saluting, the royal guard offered up an envelope. “For Princess Cadance,” he explained in clipped words, panting heavily.

Cadance stepped up behind Twilight, taking the envelope and opening it with a touch of magic, pulling out the letter to read it. A long sigh left the alicorn, and she shook her head.

“What is it?” Shining Armor asked, peering over Cadance’s shoulder.

“The Crystal Empire needs me,” Cadance said, waving the letter with a wrinkled nose. “It’s pretty urgent.”

“Urgent enough to interrupt Hearth Warming’s Eve?” Shining Armor complained.

Cadance gave a heavy, long-suffering sigh. “No one ever said being a princess was easy.”

Shining Armor heaved a long sigh, shaking his head. “Fine, fine. I’ll get our bags.”

Cadance held up a hoof. “No, you should spent Heath’s Warming Eve with your family.”

Frowning, Shining Armor raised an eyebrow. “Cadance, you are my family now.”

Cadance giggled and then leaned in to whisper into his ear, “I find it hard to believe that you would do half of what you do to me to members of your family.”

Shining Armor’s cheeks flushed faintly with warmth, and he shook his head firmly. “But you can’t go alone.”

“I will have my guards,” Cadance soothed, waving a hoof. “I will be back in a day or so, at the most. There is no need to ruin your Heath Warming’s Eve.”

“Are… are you sure?” Shining Armor asked uncertainly. “Or is this one of those tricks where you want me to go with you even though you’re telling me to stay?”

Cadance smirked, bopping his nose with a hoof. “Stay, Shiny. I will return tomorrow and we’ll make up for lost time. Anyway, I can fly, you cannot. You’ll just slow me down.”

“Impeccable logic as always,” Shining Armor said with a long sigh. “Fine, fine. I’ll stay here. Go see to your kingdom.”

Cadance smiled, clapping her hooves together. “Good boy. I’ll be back tomorrow,” she said, giving him a quick peck on the nose before turning and hurrying out the door.

Twilight watched her go with a slight frown, before turning towards her brother. “Well… looks like it’s just me and you until tomorrow, or whenever mom and dad get here.”

Shining Armor nodded, pulling his sister into a hug and scruffing her mane up with a hoof.

Twilight shied away, squirming to escape. “Hey!”

Grinning, Shining Armor ruffled her mane a little more before allowing her to get free. “So, wanna get stuck into the eggnog then?”

“We have eggnog?” Twilight asked, bouncing slightly in place. “You should know that I babble something awful when I’m tipsy.”

“When you’re tipsy?” Shining Armor asked, giving her a significant stare.

Twilight scoffed, slapping his shoulder with a hoof.

Shining Armor grinned at that, tugging open the fridge and pulling out a jug of eggnog, sitting it down on the table. “Cadance made it this morning.”

Twilight nodded once, pulling out her chair again before sitting down, emptying her mug out the window and then filling it with eggnog. She sniffed it curiously, and then took a large gulp of it. Almost a full second later, she gagged slightly and wrinkled her nose, her eyes watering.

“Too strong for you?” Shining Armor asked with a smirk, taking an indifferent gulp of his own eggnog.

Twilight wiped the tears from her eyes with a hoof, swallowing thickly. “Oh sweet Celestia that is strong! Did you just start with spirits and add a few ingredients!?”

Shining Armor chuckled softly. “C’mon, you’re just being a lightweight!”

“I am not a lightweight!” Twilight protested, scowling as she picked up her mug and tipped the contents into her mouth, swallowing it all down repeatedly.

An hour later, and the sun was falling below the horizon, gilding the cove and the cottage in pink. Twilight was reading a book, head resting on folded hooves, holding the book in front of her with her magic, occasionally taking sips from her eggnog. She was wearing a silly hat with a bell on the end over her horn, giving her a festive look.

Shining Armor was making trips back and forth between the forest and the cottage, carrying wood the old fashioned way, without magic, splitting it with an axe and then dragging it inside to stack neatly beside the fireplace. He had refused to let Twilight help, and was doing it all himself.

Both Twilight and Shining Armor were quite tipsy, having imbibed enough eggnog to give them both a pleasant buzz. Twilight’s cheeks were flushed with warmth as she read through her book, citing facts seemingly at random.

With a long sigh of relief, the stallion sat down in front of the fireplace, picking up a match and starting to steeple some pieces of wood to start the fire. A chill was falling throughout the cottage, and Twilight drew her wings up about herself to relish in their warmth.

In just a few moments, Shining Armor had a decent flame going, and then carefully dropped a pair of wooden blocks onto the fire to start a nice, roaring blaze. Almost immediately, the room began to warm up.

Humming faintly to himself, the unicorn picked up his mug of eggnog and took a long swig of it, head tilting to an imaginary tune.

Twilight shuffled a little closer to the fire, stretching her wings out to warm the feathers, wincing slightly as she stretched over-worked muscles.

“Overextended yourself?” Shining Armor asked, smiling faintly.

Twilight gave a slight nod. “I believe so.”

“Should have taken a carriage,” Shining Armor said with a shake of his head, sidling closer to his sister.

Twilight harrumphed, rolling her eyes. “Well I did the research, and with the surface area of my wings combined with my natural proclivity towards fitness, and the stiff eastern breeze from the high pressure system, I was confident I could make it without much effort.”

Shining Armor blinked once and then chuckled. “You can’t turn fitness into math, Twily.”

“Sure I can!” Twilight protested, scowling and taking another gulp of the eggnog.

Shaking his head, Shining Armor shuffled closer to her, and then leaned over her a little, hooves lifting to begin kneading and squeezing at the base of her wings.

Twilight blinked once, giving a soft sound of surprise, her wings springing outwards immediately, slapping her brother in the chest and neck.

“Wh-what are you doing?” Twilight asked, giving a faint shiver as she peered back at him over her shoulder.

“Relax,” Shining Armor soothed, kneading more firmly. “I do this for Cadance whenever she overextends herself. You need to loosen up the muscles or you’re going to be in agony for days.”

Twilight frowned deeply at that, before giving a wooden nod and returning to her book, biting her bottom lip, her blush becoming more pronounced as her wings quivered. “D-did you know that an alicorn only burns a tenth of the energy a unicorn would while levitating objects relative to body weight?”

“I did not know that,” Shining Armor responded attentively, kneading out along the upper arch of Twilight’s wings, carefully kneading and pressing against each muscle in turn, finding the knots of tension in the sore wings and systematically soothing them all out.

Twilight gave a helpless groan, splaying out on her stomach, resting her chin on the opened book, starting to drool faintly. “Oh sweet Celestia that feels good…”

“I’ve had practise,” Shining Armor said with a slight smirk, rubbing out towards the edges of the wings, and then back towards the centre.

“No pony has… has really touched my wings before,” Twilight muttered, her breathing starting to increase in speed and intensity. “I never understood why the textbooks said that wings could be an erogenous zone, they were always just so awkward and ungainly to me… and far too odd to be rubbed… but now I understaaaand…”

Shining Armor gave a faint chuckle at that, kneading against the base of her wings carefully. “Erogenous zones? Careful now, Twily, it’d be really awkward for you to start getting riled up by your brother’s hooves.”

“I concur…” Twilight murmured, her cheeks flushing even further and her eyes widening just slightly. “D-did you know that in s-some cultures mistletoe is a… a… a kind of pact or instigator of a kiss for anypony beneath?” she pointed out, motioning towards the ceiling.

Shining Armor chuckled again, an eyebrow raising slowly. “And why are you telling me this, Twily? Scared that I’ll have to kiss you?”

Twilight’s blush became even more pronounced. “N-no… I-I mean… the mistletoe is not a... a pact… i-it’s more of an instigator in that the ponies are willing participants and completely consensual and it merely seems as though it’s an aid in shy ponies g-getting close to their chosen partner.”

“You’re babbling again, Twily,” Shining Armor said with a soft laugh, shaking his head slightly.

Twilight flushed even further, stammering, “I-I-I babble when I’m n-nervous…”

Shining Armor tilted his head to the left, leaning closer to her, hooves giving a firm little squeeze at the base of her wings. “Why are you nervous, Twily?”

Flushing deeply, Twilight tried to stammer a response. “B-because of d-direct s-somatosensory s-stimulation a-and a f-fear that I’m d-developing an i-iniquitous pa-paraphilia…”

Blinking slowly, Shining Armor stared down at her, head tilting a little more to the side. “You know I didn’t understand any of that, don’t you, Twily?”

Twilight nodded sheepishly, her heart thudding in her ears, very aware of the fact that her brother’s nose was almost touching her own. “I-I tend to use b-big words when I—”

Twilight trailed off, eyes widening as Shining Armor pressed closer to kiss her, their lips meeting. She froze, her entire form trembling and tensing up, wings springing outwards against her brother’s chest again, stiff and tense.

Shining Armor smirked slightly, drawing back from the light kiss, kneading at her wings all the more intently to get them to relax and lay back down.

Whimpering faintly, Twilight turned back to face the fire, her cheeks flared with a deep warmth that made the fire pale in comparison. “I can’t… I don’t… Y-you just…”

Shining Armor nodded, his own cheeks warmed with nervousness. “Do you… do you want me to stop?”

Twilight’s eyes widened at the question, and she felt her breathing hard and heavy in her own ears. Neck straining in anxiousness, she slowly shook her head, whispering a single, plaintive, “N-no…”

A low purr left Shining Armor at the consent, his eyes narrowing down at his little sister as he kneaded his hooves against her wings, relaxing enough to let his form press over her own.

A jolt went through Twilight as she felt a certain bump against the line of her haunch. She knew enough of pony anatomy to know exactly what it was. Shining was already becoming aroused, as evidenced by the warm, heavy weight resting against her flesh, throbbing faintly in time with his heartbeat. She bit her bottom lip as Shining Armor started to rock back and forth against her, slowly grinding that growing flesh against her haunch.

Shining Armor gave a low purr in the back of his throat, kneading firmly at her wings, even as he lightly rocked against her, the mottled black-and-white length of his cock growing against her rump, brushing against her soft tail. “You are so beautiful, Twily,” he hummed, leaning up to nose through her mane, inhaling her scent.

One of the hooves rubbing at her wings slowly trailed downwards, kneading down the length of her spine. Twilight shuddered and bit her lip all the harder, her cheeks flaring with warmth as she realised where the hoof was headed, swallowing thickly as she delicately spread her hindlegs just slightly to give it room at its destination.

An eager growl left the stallion as he pushed his hoof up under her tail, letting it brush right across the lips of her cunt.

Twilight flushed even further as her brother’s hoof found her already wet and swollen, a slow trickle of her liquid drooling down her inner thigh. Her hips pushed upwards automatically as a slow groan rolled out of her throat. Her wings fluttered, brushing against Shining’s chest again.

Shuddering, Twilight pushed her hips up even further, lifting her brother’s hips with the firm pressure, before she dropped down and rolled under him, her wings lifting automatically to cover herself self-consciously. She peered over the leading edge of one of her wings, staring down the length of her brother’s form to where his growing mottled cock was stiffening to life. She stared at it, entranced, eyes wide, gasping behind the feathers of her wing, her blush deepening, burning fiercely.

“Do you like it?” Shining Armor asked self-consciously, giving a helpless wince.

Twilight stared at it, slowly lowering her wing, swallowing thickly. Her hooves lifted, lightly rubbing against Shining Armor’s sides, squeezing them delicately as she fluttered her wings and wiggled down his form.

“Where’re you going?” Shining Armor asked, his ears pricking upwards, watching the festive hat on his sister’s head disappear between his forelegs.

“Studying…” Twilight murmured shakily, as she swept in underneath him properly.

Shining Armor frowned, opening his mouth to say something before fading out into a gasp and shudder as he felt soft hooves clasp around the middle of his member and the feather-light touch of lips at his tip. “T-twily?”

“Shhh…” Twilight whispered, feathering a series of tentative kisses all over the tip of her brother’s throbbing flesh, exploring his shape with her lips. Her soft lips closed over the very tip of his cock, not even stretching all the way over the rim as she suckled very, very delicately at the centre of his tip.

Shining Armor gasped, his hindlegs tensing up and hips rolling instinctively under the stimulation. A single dribble of precum spilled from the tip of his throbbing member, drooling directly onto his sister’s tongue.

Twilight jerked in surprise as the sudden musky taste of her brother’s arousal flooded her senses, and she gave a helpless shudder, her cheeks flushing further with warmth as she slowly ground her thighs together. Her wings sprang upwards again, pushing stiffly against Shining’s chest as she shuddered and suckled all the more intently at the tip of his throbbing cock.

A soft groan left the stallion as he bit his tongue, eyes clenching closed and his breathing accelerating in speed and intensity. A shaking hoof lifted to stroke and knead at the stiff wings of his little sister, trying to soothe her and calm her down even as he became more and more agitated.

Shuddering faintly at the taste flooding across her tongue, Twilight lifted her hooves to rest on her brother’s haunches, right above his cutie mark. She squeezed lightly, feeling the strong muscles under the supple hide before tugging at his hips insistently, almost urging him to move against her.

Shining Armor gave a lustful growl, clenching his teeth as he leaned forwards slightly, starting to rock his hips back and forth, grinding the swollen tip of his cock against her lips repeatedly.

Twilight suckled all the more intently as Shining started to move, her hooves grasping and squeezing at his hips eagerly, even as she opened her mouth wider, eyes closing on reflex as the tip of her brother’s eager member sank into her mouth. Immediately, her lips closed behind the tip of the thick shaft, trying her very best not to let her teeth close around the flesh spreading her jaws. She shuddered helplessly, hindlegs twitching and kicking at the air slowly in excitement, one of her forehooves slipping down between her thighs to grind against her drooling cunny as she moaned softly around her brother’s shaft.

The stallion grunted faintly, a hindleg lifting and then stamping down on the floor reflexively, almost stamping on one of Twilight’s wings, and she snatched it out of the way quickly, pausing just long enough to extricate the length of her brother’s cock from her eager muzzle. “C-careful big brother…” she whispered, lightly stroking a hoof along the throbbing length, the words making her shiver in excitement. It made her feel young again, like she was just a little filly eager to please her big brother.

Shining Armor gave a low growl at that, his entire form seeming to tense up momentarily, another thick dribble of precum spilling from his member. It seemed that he, too, enjoyed the words. Twilight was there almost immediately to catch what spilled, muzzle parting and tongue extending to catch the thin trickle of precum across it, immediately curling up to drag a heated lick across the front of his twitching cock.

“I-I want to.. t-to taste you, big brother,” Twilight whispered, barely audible, her lips brushing against the tip of the stiffened flesh with each of her words. Her hoof ground all the more intently between her thighs, rubbing back and forth against her aching cunt over and over again as she leaned up and captured the tip of his flesh in her muzzle again, wasting no time in sinking the first few inches into her mouth.

Shining Armor bared his teeth, the hindhoof stamping against the ground again, one of his forehooves lifting to grasp her horn through the silly hat, starting to rock back and forth into her mouth, holding her steady with the hoof on her horn.

Twilight whimpered muffledly around her mouthful, eyes clenching closed, suckling in earnest around the length of her brother’s cock, her hips rolling and arching helplessly as she ground her hoof against herself. The scent of her arousal grew more apparent in the room, though she had no chance to notice it herself, what with her senses overcome by the musky scent of her brother’s potent arousal. Each firm hump into her muzzle just spiked her arousal higher, and she wanted to urge him to hump faster and harder, but with her muzzle full, she couldn’t. Her free hoof slid up to his haunch again, eagerly, almost urgently tugging at his hips, imploring him to hump into her mouth.

The stallion seemed to take the hint, groaning as he started to rock and hump into her mouth with an eager, rapid pace, his swelling tip spreading her jaws further and further as his arousal became more apparent. The dribble of his precum was almost a constant trickle now, starting to spill down from the corner’s of his sister’s lips, heralding what was going to happen when he dumped his load down her throat. His pace increased, growing in urgency and force as the male started to pant and bray in delight.

Several hard, urgent thrusts came from the stallion, before he tugged back suddenly, tugging the throbbing member out of her mouth with an audible pop!

Twilight gasped for air, panting and coughing faintly, shuddering, grinding her hoof between her hindlegs almost urgently. “W-why did you s-stop big brother?” she almost whined, panting, open-mouthed.

Shining Armor released her horn, panting himself, tongue sticking out, his cheeks flushed with exertion and a visible tremor passing through his cock every few moments. “I-I was going to cum,” he managed to pant out.

The rosy blush on Twilight’s cheeks intensified, and she bit her bottom lip, looking away. “D-do I make you that e-excited… big brother?”

Twilight watched with interest as her brother’s cock throbbed wantonly at her words, and he clenched his teeth, giving a jerky nod.

Biting her tongue, Twilight started to grind her hoof against her swollen cunny all the more intently, her free hoof lifting to tentatively stroke along his haunch again. Her head lifted, and she feathered the lightest of kisses along his tip. “I want you…” she whispered breathily.

“What was that, Twily?” Shining asked distracted, helplessly rolling his hips against her muzzle.

Twilight didn’t answer, lifting the hoof from between her thighs to lay on the side of his member, squeezing it lightly, spreading her own slick liquids along its length. Her tongue swirled firmly along the tip of his cock, before she engulfed the first few inches without warning, grinding her tongue directly against his tip while starting to suck, all the while jerking him off with the firm grasp of her hoof.

Shining Armor tensed up all over, his eyes widening and a breathless gasp leaving him as he humped on reflex, urgently trying to sink deeper into his sister’s muzzle. Twilight held on doggedly, keeping a firm grasp around his thrusting cock to keep the relative movement at a minimum, grinding her tongue against his tip repeatedly and suckling powerfully at him.

The entire tip of his cock started to throb and pulse, thickening and swelling, spreading his sister’s jaws wider and wider as he urgently rocked back and forth. “T-Twily!” he cried in warning, the hoof grasping around her horn again on reflex.

Twilight groaned faintly, trying to nod against him, to urge him to hump and spill into her mouth, only managed to translate the nodding of her head into a firm dip and bob along his stiff cock. Almost immediately, hot bursts of spunk started to spill into her mouth.

Eyes widening, Twilight gagged at the sheer ferocity of the stallion’s orgasm, the thick, sticky liquid spilling rapidly into her mouth with surprising force. It burst up against the back of her throat, volleys of the thick liquid filling her to the brim in an instant, like the one time when she was a foal trying to drink from the garden hose. A gush of the liquid spilled from her lips, washing back over her brother’s jerking, throbbing cock, spilling down her chin in sticky rivulets to meet at the centre of her chin and drip slowly down into the hollow of her throat.

Almost urgently, Twilight started to swallow, trying to keep up with the impressive volume of his spray, tongue pushing up against his tip to protect her throat from the forceful spray, letting the pulsing streams of his spunk splash directly against her tongue. More and more of his liquid spilled from between her lips, just making her muzzle even messier, until finally, his spurts slowed.

Ten full seconds of orgasm, though it felt like an eternity to Twilight. She suckled firmly around her brother’s cock, tongue grinding against his tip to coax out the last few bursts of his musky spunk, reveling in the primal taste inundating her senses.

The hoof grasping around his cock slipped down her form, pushing past her stomach to grind urgently between her thighs again, rubbing back and forth against her aching cunt as she slipped her lips from over his cock. The final burst of his seed spilled down over her chest and throat, even as she arched and quivered in her own orgasm, biting her bottom lip and arching underneath him, wings splaying hard against the ground.

Shining Armor panted heavily, taking a shaky step backwards to stare down at her, watching his little sister writhing in her masturbation-induced orgasm, eyes clenched closed, biting her bottom lip, splattered liberally with his spunk.

Twilight slowly came down from her euphoria, gasping and whimpering softly, licking at her lips distractedly, her tongue carrying a sticky white coating of her brother’s spunk. Her eyes slowly opened, and she stared up at him, catching him watching her. Her eyes widened and she lifted her wing to cover her mouth again, giving the faintest of whimpers, her cheeks flaring with intense warmth.

“I… I need to get cleaned up…” Twilight whispered, her voice cracking, rolling out from underneath him and bolting towards the bathroom. Shining Armor watched her go with a hazy stare, before collapsing onto his stomach.

Twilight whimpered helplessly, leaning over the sink, one hoof dipping into the basin to then brush over her lips and muzzle, trying to clean up the sticky mess that was coating her features. Her free hoof was stuffed beneath herself, pushing firmly up against her drooling cunny again and again, rubbing urgently back and forth.

There was a light touch at her rump, and she jerked in surprise, shoving herself against the sink accidentally, wincing.

“Hey, hey, calm down, Twily,” Shining Armor said soothingly, smirking faintly. “I’m just… decorating.”

Twilight blinked once, twisting to stare over her shoulder, to see Shining Armor holding the sprig of mistletoe in one hoof. “W-what?”

Shining Armor didn’t answer, just pushing her tail upwards with a hoof, and then hooking the mistletoe to the base of it, smirking at her over her rump. “So… you said that in some cultures… they kiss under the mistletoe?”

“B-but the mistletoe is placed somewhere up high to facilitate the kissing undern–” Twilight trailed off as she realised what her brother was implying. “I-I-I m-mean it’s h-ha-hardly,” she stammed brokenly.

Chuckling faintly, Shining Armor ducked underneath her tail and then laid a firm kiss right against her lips of her cunt.

Twilight gasped and whimpered, her legs going shaky, both hooves clutching onto the sink for balance, her eyes widening and wings springing outwards on reflex.

Shining Armor didn’t miss a beat, pushing his nose firmly up against his little sister’s tight cunny, a hoof lifting to grasp her rump as he dragged another warm lick against her, tasting her liquids.

Whimpering faintly, Twilight stuffed a hoof in her mouth, her wings quivering and jerking stiffly over her back as she rolled her hips, weight shifting from hoof to hoof.

An eager rumble left the stallion as his hoof slipped in, lightly touching at the side of her plump cunt, before applying firm pressure. The lips of her swollen cunt, covered in the soft purple fuzz that was apparent on the rest of her body, spread open, revealing the soft, slick pink of her inner flesh.

Twilight shuddered, peering at her brother over her shoulder, ears pinning back, the bell on her hat jingling softly as she quivered, feeling herself being spread open and watching her brother’s hungry gaze linger on her exposed flesh.

Without warning, Shining Armor leaned in and dragged a heated lick right across the exposed inner flesh, soft, velvet tongue grinding across the supple, smooth pink flesh of her swollen cunny.

Twilight fairly screamed, her wings fluttering and flapping on reflex as she arched and jerked helplessly under the firm stimulation of her brother’s tongue grinding against her inner flesh. Whining faintly, she slipped a hoof back to grasp her own rump, spreading herself to him, revealing the soft pink of her inner flesh. “M-more…” she panted breathlessly, a hindhoof stamping against the floor. “P-please lick me more big brother…”

Shining Armor gave an eager growl at that, pushing forwards to drag a heated lick against her swollen cunny, grinding his tongue against her firmly, the powerful muscle forcing her open to sink into her. Slick dribbles of her liquids spilled down across his tongue, coating it in her taste.

The alicorn whimpered helplessly, her entire form spasming as a small orgasm coursed throughout her form, her stiff wings quivering and jerking as her insides spasmed around his tongue, clenching against it repeatedly.

“B-big brother…” she whined, looking back at him with one large, wide eye. “I-I n-need you…” she whined heatedly, lifting her hips a little higher.

Shining Armor’s eyes widened, and he dragged one last lick against her, before drawing back slowly, straightening and staring at her, starting to breathe faster and harder.

“P-please…” Twilight whimpered, slipping a hoof back along her stomach to rub at her clit slowly, deliberately pushing with just enough pressure to cause those swollen lips to spread and reveal the soft pink of her inner flesh.

Shining Armor bit his tongue, looking away for a moment, swearing quietly, before striding up behind his sister, immediately wrapping his hooves around her hips, cheek resting against one of her stiff wings. “Are you sure about this, Twily?”

Twilight nodded anxiously, shifting her hips slowly back towards his own, seeking to grind against his member. “Y-yes… I need it!”

Nipping at her mane heatedly, he shifted to grind himself up under her tail, his stiffened member pushing right up against her rump, grinding across the mistletoe before finding his mark and pushing directly against the drooling lips of her swollen cunny.

Twilight shuddered, stiffening, her entire form quivering in anticipation as she delicately pushed herself back against him, pushing the tip of his cock right up against her aching cunny.

“T-Twily,” Shining Armor murmured, gritting his teeth for a moment as he ground himself directly against her. “A-are you sure about this?”

Twilight grit her teeth in response, glaring at him over her shoulder. “S-shining, if you don’t engage in intercourse with me right now, then so help me Celestia I wi—”

The alicorn stiffened and went rigid as her brother suddenly ground forwards, sinking several eager inches of stiffened stallion cock deep inside her, spreading her around him with warning. A scream of surprise and helpless delight left her, and she arched her back, collapsing against the sink which a shudder.

Shining Armor caught her around the middle, grasping her tightly to help keep her steady as she quivered weakly in his grasp. “F-fuck Twily,” he groaned against one of her ears.

Twilight flushed deeply at the profanity, her ears pinning back and hips pushing back against him on reflex, trying to get him deeper. “F-fuck me big brother,” she whined, fumbling over the dirty, unfamiliar words.

“You have no idea how sexy that is,” Shining Armor whispered into one of her ears, before taking it between his teeth in a lustful bite, grasping her hips tightly and then shoving himself deep inside her, rocking his hips against her eagerly.

Twilight arched and cried out, the bell on her hat jingling merrily with each firm rock of her brother’s hips, pushing her against the sink and spreading her around his stiffened cock.

Shining Armor growled around her ear, hooves squeezing her sides and hips as he started to hump and grind deep inside her, each firm push of his hips sinking a little bit deeper into his sister’s clenching depths.

Slick dribbles of Twilight’s liquids lubricated his cock as he worked back and forth, the soft flesh of her cunny squeezing and rippling around him in eager spasms, making it easier for him to hump, but also increasing the friction, rapidly driving up the pleasure the siblings were reveling in.

“F-fuck me harder!” Twilight snarled into the sink, her hindlegs straightening and stiffening, helping to hold herself up to be ravaged by her brother’s desires. She pushed her hips back against him in counterpoint to each thrust, trying to get him deeper.

“Fuck!” Shining Armor snarled, hooves grasping around her middle all the more tightly, squeezing her almost painfully tight, his hips starting to shove into her with urgent little eager motions. “Too t-tight!”

Twilight grunted helplessly as she pushed back against him firmly, hips rising to meet each of his powerful thrusts, the firm shoves of the thick cock overcoming her resistance bit by bit, until finally, he could sink into her fully.

It was a perfect fit, each inch of stiffened, throbbing cock buried deep inside her, with her swollen, clenching lips squeezing around the base of the twitching cock. His tip was pushed right up against her deepest barrier, brushing against it with each hilt-deep thrust, causing a delicious jolt to rock the female’s form with each firm hump.

Twilight screamed again as she came, her entire form tensing and convulsing repeatedly, wings fitfully fluttering against his chest. But it was nothing compared to the eager, intense clenching of her cunt, squeezing and rippling around her brother’s cock in repeated spasms.

“F-fuck, T-twily,” Shining Armor warned, grasping her hips tightly and starting to shove into her with powerful, rough thrusts, pinning his little sister to the sink with his superior strength. “Gonna… gonna cum…”

“Y-yes!” Twilight babbled, almost incoherent with the euphoria of repeated orgasms forced onto her by her brother’s powerfully thrusting cock. “F-fuck me big brother!”

Shining Armor snarled at the words, coaxing out his need to fuck his little sister into a stupor, starting to rapidly rut into the clenching female with rapid, unforgiving strokes. Each firm thrust sank himself deep inside her, spreading her right down to her core, until his swelling tip bumped up against her deepest barrier.

Twilight screamed repeatedly as she came again and again, rocking her hips weakly back against the thrusts of her brother, her hindlegs getting shaky and unable to hold her weight.

Powerful hooves grasped around Twilight’s hips, holding her aloft as he pounded into her with unrelenting shoves, the swelling of his tip deep inside her just causing a more powerful shove against her cervix at the end of each hump. The jingle of the bell on her hat sounded with each eager drive of his hips, becoming a sharp chirping sound as the pace increased.

After just a few more thrusts, Twilight collapsed onto her chest, a drooling, euphoric mess of repeated orgasms, her inner thighs quivering and splattered with her own liquids as her brother pounded down into her form urgently, letting gravity take over the work of spreading that supple cunt for him.

With a snarl, he shoved himself deep inside her, holding against her, his tip grinding up against her deepest barrier over and over again before sudden rapid splatters of spunk spilled across it, splattering warming across her insides.

Twilight’s eyes widened, and she froze, screaming out hoarsely as she felt her brother dumping the rich loads of potent spunk deep inside her. She swore she could feel each burst of it powerfully splattering across her inner flesh, coating it in the sticky, heavy burst. Each volley of her brother’s spunk coating her made her jerk and shudder, biting down on her tongue and tensing in helpless orgasm, clenching around him urgently to coax out as much of the potent liquid as she could get.

Shining Armor snarled as he spilled deep inside her, hips driving into her jerkily, each firm shove into her forcing a slick dribble of white to spill from around their interlocked bodies, drooling around his cock and dripping from Twilight’s clit, creating a messy puddle beneath them.

After several long moments of glorious orgasm, the two siblings collapsed onto the bathroom floor, Shining’s cock still buried deep inside Twilight’s spasming, clenching cunny.

The front door of the cottage opened, and Cadance, and the Sparkle parents stepped inside.

Shining Armor and Twilight were sitting at the table, playing scrabble and sipping coffee.

They both looked up, waving hooves in the direction of their parents and Cadance.

Cadance gave a long sigh, pulling out a chair and sitting down. “I trust you two enjoyed yourself while I was gone?”

Twilight and Shining Armor nodded as their parents pulled out seats at the table as well.

“We just ‘reveled in paraphilia’ while you were gone,” Shining Armor said with a smug smirk.

Twilight choked on her drink, snorting into her cup, her cheeks pinkening just faintly.

Cadance looked back and forth between them uncertainly. “You know I don’t know big words like that. Are you and Twilight creating a secret language so you can talk behind our backs?”

Shining Armor just gave his wife his most innocent smile, and Twilight shook her head.

“No, Shining and I were just Pontificating on the potential happenstance of furthered intemperate paraphilia,” Twilight said with a blank expression.

Cadance blinked, looking back and forth between the two siblings. “You two are probably glad I don’t have a dictionary, aren’t you?”

“Oh Celestia yes,” Twilight said, smiling faintly, while her and Shining exchanged a mischievous stare.

Hooves-on Experience

“Whatcha reading, Twily?” Shining Armor queried as he flumped down on the couch, sending up a tiny puff of dust.

Twilight looked up from her heavy book with a smile. “Unicorn physiology!” she said excitedly, giving the smallest of bounces in place on the other end of the couch.

The two siblings were now old enough that their parents didn’t feel it necessary to hire a babysitter to look after Twilight when they left for the evening. This decision was much to the rue of Shining Armor, as he couldn’t spend time with Cadance. Or more specifically, he couldn’t take her upstairs to his room after Twilight was asleep and screw her into the bed.

It was only an hour into the evening, and the sun was barely going down, and already Shining Armor was bored.

“Anything interesting in there?” Shining Armor asked, ears perking upwards hopefully.

“Oh, nothing much really,” Twilight admitted, frowning slightly. “I know most of this already.”

“I’ll quiz you,” Shining Armor offered, snatching the book from her grasp and turning it around to peer at the page. His eyes widened slowly and his jaw dropped.

A cut-away image of an aroused stallion was splashed across the page, in perfect detail, with various informative tags pointing at the different parts of the gigantic cock and testicles.

Shining Armor’s eyes boggled.

Twilight arched an eyebrow.

“You’re… wow, Twily,” Shining Armor said, looking from the page, up to his little sister. “Why are you… looking at a giant picture of a stallion’s cock?”

“It’s part of the curriculum,” Twilight said easily, shrugging her shoulders slightly. “I learned the anatomy of a mare last week, which was easy considering I am a mare. But the stallion is harder because, well, there are no stallions around willing to let me study them.”

Shining Armor pondered on that for a long moment, looking down at the page, and then up at his sister. “...I’m a stallion.”

“I’m aware,” Twilight said, deadpan.

“Well, if you need to study a stallion for school…” Shining suggested, trailing off slowly, raising an eyebrow.

Twilight gave a thoughtful hum, mulling it over. “You’d let me study you?”

“It’d be my pleasure!” Shining Armor attested with an eager nod.

Twilight smiled brightly. “Sure, then!”

“Just ahhh… we should keep this to ourselves, some ponies might think it a little weird that I let you study me,” Shining Armor cautioned.

Twilight nodded once. “Yeah, that might raise some eyebrows,” she admitted.

Shining Armor grinned at that, sitting up straighter on the couch and then turning toward Twilight, leaning back until his back was pushed against the arm of the chair, pausing a few moments before spreading his hindlegs to reveal his thickened sheath to his sister.

A thoughtful hum left the unicorn, and she peered in at him curiously, leaning in to inspect him closely. “From the colour, I suspect that it’s black when fully erect?”

Shining Armor gave a nod. “Yeah, kinda black and grey.”

“Can you get erect for me?” Twilight asked, peering up at him with inquisitive purple eyes.

Pausing for a moment, Shining Armor gave a slow nod, a smile spreading across his muzzle. “Sure… sure… just give me a moment to think of something.”

One of Shining Armor’s hooves slipped down his form, rubbing slowly at the rim of his sheath, coaxing out the hidden flesh.

“Why don’t you think of Cadance?” Twilight suggested with a thoughtful hum. “She’s quite attractive.”

“She is,” Shining Armor said with a slow nod, staring down at his litter sister, eyes narrowing slowly. “Could you… lend me a hoof?” he asked cautiously.

Twilight blinked once, biting her bottom lip, looking unsure and nervous for the first time since they had begun. “I… I guess so,” she said after a moment, lifting a hoof to place over his own.

Shining Armor grinned, sliding his hoof away and leaning back, watching his little sister with avid eyes as her hoof came to rest on the swelling length of mottled black cock.

Peering in at his growing flesh thoughtfully, Twilight started to rub her hoof over it, gently tracing its lengthening contours. “it’s kinda spongy…”

“It gets harder,” Shining Armor said with an earnest nod, watching with interest as her hoof coaxed him out.

Twilight hummed to herself, sliding her free hoof down to heft his testicles, gently lifting each one. “Quite heavy…” she muttered to herself, the faintest of blushes spreading across her muzzle.

“Are you… sexually active, Twily?” Shining Armor asked after a moment, panting just faintly as his thick length grew and swelled into the touch of her hoof, quickly throbbing to full size.

Twilight nodded slowly, staring up at him.

“Do you… masturbate?” Shining Armor asked, eyes wide, panting faintly, his stiffened cock giving an eager throb as he asked the question.

Twilight nodded once more, but didn’t answer verbally.

“What do you think about when you masturbate?” Shining Armor asked, his hips shifting on reflex, even as a dribble of precum slowly spilled from the tip of his stiff cock.

“Stallions,” Twilight said quietly, stroking her hoof delicately up the length of his cock, tracing his medial ring, and then smearing the dribble of precum across the underside of his thick, spongy tip. “Big… throbbing penis’…” she whispered, staring at the stiffened cock, almost entranced. “You and Cadance…”

Shining Armor blanched at that. “W-what?”

Twilight nodded once. “You and Cadance. I watch you sometimes, when you think I’m asleep,” she said matter-of-factly.

A faint shudder coursed through Shining Armor’s form, and he gave a nervous chuckle. “I didn’t think you knew about that…”

“She is quite a skilled lover, isn’t she?” Twilight asked, tracing the length of her brother’s cock with her hoof. “I’m done here,” she said suddenly, pulling her hoof away.

Shining Armor almost whimpered. “D-done?”

“I’ve learned all I can,” Twilight said with a nod. “Thank you for showing me, Shiny.”

Shining Armor flailed a hoof. “N-no wait!” he panted, giving a strained sort of smile. “Don’t you want to… uhm…”

“Want to what?” Twilight asked, an eyebrow raising slowly.

“O-oh just get some.. u-uh… hooves-on experience,” Shining Armor said with an earnest nod. “After all… if you want to be as skilled as Cadance, then you’ll have to practise… practise makes perfect!” Shining Armor said with a strained smiled, his expression hopeful.

“You’ll let me stroke you to orgasm?” Twilight asked, giving him a long stare.

Shining Armor nodded eagerly. “Yes!” he said, before clearing his throat and looking away. “I mean, yes. Yes I will.”

“Well… it would be a good learning experience,” Twilight said, scratching her chin thoughtfully.

Shining Armor was already leaning against the arm of the chair, propped up on his back, hindlegs spreading wide, thick cock throbbing upright in his lap. “Use your tongue…” he said breathlessly, watching her with an avid stare.

Twilight arched a brow. “All in the interest of studies, right?” she asked dubiously.

Shining Armor nodded earnestly, his stiffened cock giving an urgent throb. “Yes, Twily. In the interest of studies,” he purred, biting his bottom lip as he watched her with interest.

Twilight seemed to shrug, leaning in with a curious stare, judging the size of his cock. “It’s much larger than I estimated,” she said thoughtfully. Shining Armor went to answer, before fading off into a gasp and shudder as his little sister dragged a warm, tentative lick against the underside of his cock.

“Like that?” Twilight queried, peering up at him for guidance, tongue extending to lap at him again.

Shining Armor nodded in earnest, biting his bottom lip again. “Y-yeah, Twily, just like t-that!”

Twilight gave a soft shudder of arousal as she lightly dragged her tongue up the length of her brother’s stiffened cock, nostrils flaring as she inhaled his scent.

“O-oh geeze, Twily, that feels good,” Shining Armor groaned, watching his little sister with interest, teeth baring just slightly as her tongue flicked off the underside of his tip.

“You taste strange…” Twilight said, working her jaw thoughtfully. “But I like it.” With a low purr, the young unicorn leaned in and closed her lips over the very tip of his cock, tongue pushing up against the round nub of his urethral process, grinding against the sensitive little expanse of flesh as she suckled wantonly.

Shining Armor gasped aloud, his hips shifting on instinct, ears splaying flat and a hoof flying to her head, brushing through her mane. “H-holy g-geeze…” he stammered.

“My books are very informative,” Twilight purred, delicately lapping at the tip of his cock, idly swirling her tongue around the glans, closing her lips over it to suckle again gently. A spurt of precum spilled up over her tongue, and she whimpered faintly at the taste, swallowing thickly.

Shining Armor groaned helplessly, his hips rocking back and forth against her motions slowly. “O-oh fuck, Twily, that feels good,” he groaned, hoof clenching in her silky mane.

“Better than Cadance?” Twilight asked innocently.

Shining Armor nodded in earnest. “Y-yes!”

Twilight smiled up at him, her expression turning mischievous. “I’ll let you… ejaculate in my mouth, if you return the favour…”

Shining Armor shuddered helplessly, swallowing thickly and staring down at his little sister. “Are you… are you getting aroused?”

Nodding slowly, Twilight gave another slow lap against the tip of his stiff member. “Yes. Very.”

With a lustful growl, Shining Armor rolled forwards, a hoof pushing Twilight away just slightly, before pressing down against her chest, slowly pushing her over onto her back.

Twilight blinked once, struggling faintly at first, before allowing her larger brother to push her onto her back, until she was almost flat. Tentatively, she slowly spread her hindlegs.

Shining Armor stared down at her, giving a low, lustful growl, his eyes falling on his little sister’s already-drooling, barely-mature cunny. With a quick push of his hooves, he lifted his sister’s entire lower body, pushing a pillow under her lower back to keep her leveraged, presenting her soft cunny his gaze.

The soft purple fuzz of fur that covered her entire body persisted even there, slightly damp now with Twilight’s arousal, covering the entire outer surface of her plump cunt. The faintest glimmer of pink flesh was visible between the soft purple lips.

Shining Armor shuddered, leaning in and inhaling, smelling the sweet scent of his little sister’s arousal, before he dragged a heated lick right against the soft expanse of the slick cunny. The heated taste of his sister’s arousal flooded his senses, and he gave an eager, lustful growl, digging his tongue in against her wantonly. A forehoof slipped up, wrapping around her lower back to rest on her side, squeezing and stroking back and forth just gently, even as he stared down at her over the smooth swell of her stomach.

Twilight stared up at him, biting her bottom lip, her back arching a little further on reflex, pushing her hips up towards the brush of her brother’s tongue tingling across her aching cunt so wonderfully. A slick dribble of her liquid welled up from within her, quickly lapped up by the omnipresent tongue.

An eager growl left the stallion, and he dragged his tongue against her all the more eagerly, pushing it firmly up against the soft lips of her sex, digging into the sweet crevice of her cunny to push against her inner flesh. His free hoof lifted, pushing at her inner thigh, spreading her open just a little with the pressure to let his tongue graze directly against the exposed soft, pink flesh.

Twilight arched under the touch of his tongue, groaning helplessly, muzzle parting in a heated gasp, a hoof reaching forward blindly to grasp at her brother’s horn helplessly, tugging him against her eager, clenching sex all the more firmly.

Shining Armor gave a lustful growl, panting heatedly against the plump lips of his little sister’s spread cunny, his nose pushed rather firmly up against her clit while his tongue ground against the base of her spread lips. With a smirk, he dragged a warm lick along the length of her drooling slit, to find her little clit at the apex of her cunny, closing his lips over it.

Twilight’s eyes widened and she stuffed a hoof in her mouth as she fairly screamed, her powerful thighs clenching around Shining’s head repeatedly as he suckled at her clit. Almost immediately, a slick dribble of her liquids spilled up against his muzzle, coating his chin in her arousal.

A soft chuckle left the stallion, and he idly suckled at her clit a little more, before pulling back to slowly swirl his tongue against the drooling slit of her cunny. “As you can see, I have studied extensively.”

“I concur,” Twilight muttered distractedly, blinking several times in a hazy fashion. “I’d give that a passing grade.”

“I can’t think of any good school puns, Twily,” Shining Armor admitted, releasing her rump and letting her fall gently to the couch, even as he leaned back and sat down once more, the stiff length of his eager cock bobbing up in the air. “But I really, really want you to finish me off.”

“I’m definitely ready to pass my oral exam,” Twilight breathed, purple eyes narrowing on the twitching length of her brother’s cock. She rolled carefully over onto her hooves, before dropping down onto her stomach and chest, pushing her nose right up against the midpoint of the thick length. “This isn’t weird, is it?”

“Sweet Celestia, no,” Shining Armor assured, stroking a hoof through her mane in encouragement. “I’m just helping you study for your test.”

“This seems a bit more intense than just some simple studying…” Twilight admitted, before shrugging inwardly and then leaning up to drag her tongue against the tip of her brother’s cock with an eager growl.

Shining Armor winced slightly in surprise and delight, spreading his hindlegs further to give his little sister the best access possible, panting down at her, watching with avid interest.

A soft giggle left the female unicorn, and she lipped delicately at the underside of his tip. “I haven’t seen you stare this intently since the first time Cadance took a bath with the door open.”

Shining Armor flushed just faintly at that, lifting a hoof to rest in her mane, even as his hips rolled against her muzzle, grinding himself against her lips heatedly. “Shush, Twily. You have studying to do.”

Twilight gave a derisive snort, trailing a hoof up the length of throbbing flesh. “I bet I could make you finish in record time…”

“This is hardly a race… but I would prefer you start sometime soon,” Shining Armor admitted with a slight frown, grinding against her lips pointedly.

Twilight giggled devilishly, one of her hooves unconsciously slipping down to push between her thighs, rubbing slowly over her still-drooling cunny as she spread her lips and then slipped her brother’s stiff cock between them.

Shining Armor gave an eager growl at that, watching with unguarded interest as his little sister stretched her jaws wide around his swollen cock, capturing his tip to suckle and lip at slowly. He leaned backwards with a soft, contented groan. “O-oh fuck, Twily, you have no idea how good that feels…”

Twilight nodded once, causing a slight dip over his cock and a swooping sensation in her brother’s stomach at the sensation. “I have some idea,” she purred around her mouthful, before smiling up at him.

Blinking curiously, Shining Armor kept his eyes on her own, watching as she smiled rather harder than usual, seeming to strain to keep the expression as she suddenly slipped down him far, far further than she had any time previously. His eyes widened and his back arched on reflex as his tip slipped down her throat, swallowed up by the intense tightness, and the soft, urgent tugging of his little sister’s convulsive swallowing.

Twilight shuddered, feeling her throat stretching around the thick length of cock, a whimpered exhalation brushing against the base of his flesh as she continued to smile hard around her mouthful, unable to stop the convulsive swallowing, but noting the way each firm tug of her throat muscles caused her brother to twitch and shudder.

“O-oh sweet Celestia!” Shining Armor gasped, his hindlegs twitching and kicking on reflex, his hoof grasping at her mane in a helpless scrabbling. Not even Cadance could do that!

Shuddering faintly, Twilight shifted her hoof to the base of his cock, working her muzzle back and forth for a few long seconds, before tugging back with a gasp for air, panting hard, tongue hanging from her muzzle, several strings of saliva hanging from her lips and tongue.

“T-that is a lot hard than the book said it would be,” Twilight panted breathlessly, cheeks flushed slightly with the exertion, before she leaned back in to suckle and lip at his tip almost playfully. “G-give me a moment to catch my breath.”

“You don’t have to keep doing that,” Shining Armor suggested, panting faintly as he watched her, his cock throbbing almost painfully. “Don’t hurt yourself on my account.”

Twilight peered up at him, grinning wildly. “But I want to get perfect marks,” she protested, even as she grasped the base of his cock again, and then shoved her muzzle back down around him. Almost immediately, her nose was buried in against the base of his cock, and purple eyes, eager for approval, were peering up at him from the bottom of his aching cock.

Shining Armor nodded urgently down at her, biting his bottom lip and then clenching his eyes closed. The image of his little sister deepthroating his cock and seeking his approval for the act was too much.

Twilight purred eagerly around him, a hoof wrapping around his hips while the other slipped down to idly play with her drooling cunny, even as she started to bob and thrust her head back and forth over the stiff length of his cock. Even few bobs, she would pull back to breath, panting faintly against the tip of his length, tongue idly lapping at the throbbing tip in between rapid panting.

“T-Twily,” Shining Armor warned almost urgently. “I-I’m getting close.”

“Will I get extra marks if I let you ejaculate in my mouth?” Twilight asked, perking up almost instantly.

Shining Armor clenched up at that, growling lustfully and grasping her mane in his hoof, eagerly humping towards her muzzle. “Y-yes! All the extra marks!”

Twilight gave a muffled ‘mrrfmph!’ of happiness, the hoof from between her thighs, slick with her liquids, slipping up to grasp around his testicles, squeezing gently while she bobbed along his stiff cock almost urgently.

Shining Armor shuddered, his eyes rolling back and a forehoof grasping at the back of the couch, while his other shoved hard into the cushion, giving a few firm humps into his little sister’s mouth as his eager cock stiffened and jerked wantonly.

Even with her foreknowledge from the textbooks, Twilight wasn’t quite ready for the explosion of eager, potent spunk that suddenly inundated her. One moment her brother’s flaring cock was spreading her jaws open, and the next, she was just drowning.

Burst after urgent burst of heavy, sticky cum spilled across her tongue, filling her mouth to overflowing almost instantly. Twilight swallowed on reflex, eye widening at the rich, heady taste of her brother’s arousal slipping down her throat in a thick, sticky stream. But then came the next burst, and the next, rapidly overwhelming the volume of mess she could swallow down. The young unicorn started to panic, patting at her brother’s hips with her forehooves helplessly as a thick dribble of his gooey mess started to drool and spill from the corner of her lips, meeting at the centre of her chin and trickle down the fur of her throat in a messy stream.

Shining Armor gasped heavily as he tugged backwards, a hoof rapidly stroking at his still-spurting cock, spilling several eager spurts across his little sister’s face. Twilight winced backwards, one eye closing as a line of mess spilled across her cheek and another caught across her muzzle. She shuddered, needing to breath, and opened her muzzle up with a whine of distaste, having to let a gooey streamer of her brother’s mess spill from her open mouth and drool to the couch as she panted heavily.

In a hazy afterglow, Shining Armor looked down at his little sister, catching sight of her, open-mouthed and panting, tongue and lips coated in his spunk, with lines of his eager emissions across her face and cheeks, staring up at him with wide eyes.

“Oh that has to be worth top marks, Twily,” Shining Armor said, before giving a helpless chuckle and a shudder of delight.

Twilight panted heavily, jaw working slowly as her brother’s taste inundated her senses. She closed her mouth, swallowing thickly, the mess in her mouth shifting down her throat in a visible lump. “I was not ready for that,” she admitted, lifting a hoof to wipe off her chin. “I’ll be ready for it next time.”

“N-next time?” Shining Armor squeaked, his eyes widening slowly and his tail starting to swish back and forth in anticipation.

“Well… I hardly passed the grade this time, did I?” Twilight asked, motioning towards her messy muzzle.

Shining Armor gave a soft laugh at that, scratching at his chin, a mischievous smile spreading across his features. “Well...y’know… you might need a few more private lessons.”

Twilight nodded with a slow smile, beginning to idly lick her hoof clean. “I intend to get full marks for my oral exam.”

Mistaken Identity (Nightmare Night)

Nightmare Moon looked at herself in the mirror, eyes narrowing slightly, inspecting her form. Her helmet was fitted perfectly, her wavy blue mane was just the right colour and density, and her sleek black fur was perfectly smooth.

Behind her, a second Nightmare Moon watched over her shoulder, giving a smile that revealed her two elongated canines. “These are so perfect!”

Even her voice was that of Nightmare Moon, even if the pony ‘underneath’ was not.

Twilight looked back over her shoulder, giving a nervous smile, her new black wings flexing anxiously. “Are you sure it’s okay? I got them as close to Nightmare Moon as I could.”

“They’re perfect,” Cadance responded, stretching out one of her own wings to inspect it curiously. “You said this magic will last hours?”

“Forever, if it’s not reversed,” Twilight said with a slightly nervous giggle. “But it’s simple enough to dispell. You do remember how to dispell it, right?”

“Just a simple spell,” Cadance said with a toothy smile, stepping in a slow circle, examining herself in the mirror. “You’re absolutely sure Luna doesn’t mind?”

Twilight nodded once. “I made doubly sure. She’s not even going to be Nightmare Moon tonight, she’s going as a Shadowbolt.”

“A Shadowbolt?” Cadance asked, inspecting her hoof, lightly tugging at one of the coverings with her new longer teeth. “Copying Rainbow Dash from last year, I presume?”

“Well, the suits are rather nice,” Twilight admitted, giving a helpless shrug. “To each their own. So… I’ll go terrorize Ponyville, and you can stay here and terrorize Canterlot?”

“Sounds like a plan!” Cadance said, before frowning to herself, brow furrowing thoughtfully.

Twilight looked back over her shoulder again. “What are you thinking?”

“Me? Oh. Just, you know, wondering where your brother is,” Cadance said with the slightest of wicked smiles spreading across her muzzle. “I could terrorize him with this form.”

“What’s he going as this year?” Twilight queried.

“A batpony,” Cadance said with a smile. “He’s got these goofy wings glued to his back, and he borrowed some armor. Keeps trying to creep up on me and pretend to suck my blood.”

“Batponies don’t… really drink blood do they?” Twilight asked blankly, wracking her mind for anything she had read on them.

“Not that I know of,” Cadance said flippantly. “He just thinks it’s funny.”

“Goofball,” Twilight said, shaking her head. “Well, you terrorize here. I’m off to Ponyville!”

Twilight was moving towards the window when Cadance stopped her. “Twilight, wait.”

Pausing, Twilight looked back over her shoulder, wings half-unfurled.

“Don’t fly,” Cadance said firmly. “You’re… relatively new to wings and flying in different forms could be… awkward.”

“I flew just fine as a breezie,” Twilight countered.

Cadance arched one of Nightmare Moon’s eyebrows. “And if you hit terminal velocity as a breezie, would it shatter every bone in your body on impact?”

“Point taken,” Twilight said, nose wrinkling slightly as she turned and headed for the door instead, giving a weary sigh. “But it’s so far to Ponyville…”

“Nopony ever said that being a trickster was easy,” Cadance said with a wry smile. “Maybe you can frighten some colts and fillies on the way there?”

Twilight kept her head down as she walked down the Canterlot streets. Occasional colts and fillies crossed her path, and she made sure to smile and widen her eyes under the cloak whenever eye contact was made.

The eerie glow of her eyes and teeth in the shadowy recesses of her cloak made each and every one of them bolt down the streets, screaming in terror.

Twilight’s smile became more real as she watched the foals bolt away, and she felt slightly better about her plan for the night as she headed for the long, long path down to Ponyville.

The path to Ponyville was lit with the eerie orange glow of a thousand burning jack-o-lanterns, with bats occasionally swooping past the lights, and fake spiders hung from the trees. The twists and turns of the path were hardly vacant of ponies, but each individual stretch that didn’t have any ponies in it seemed utterly empty and devoid of any life.

“My Princess!” a familiar voice called, and Twilight blinked once, snapping to attention, looking back over her shoulder.

A batpony stood on the path behind her, dimly lit by the jack-o-lanterns, his features indeterminate in the gloom.

Twilight opened her mouth to tell the batpony that she was just in disguise, and not actually Luna, when the batpony stepped forwards and her eye caught the black-painted spire of a unicorn horn poking up from his forehead.

Blinking once, Twilight tilted her head to the left, before giving a toothy smile. It had to be Shining Armor!

His makeup was immaculate, and with the special armor set of the dark guard, he looked exactly like a batpony in low light. The wings, drooping listlessly at his sides, and the horn poking from under the askew helmet were the only things that gave him away.

“Yes, my subject?” Twilight asked, playing along, rounding on the stallion. She was taller than him now, and it was very strange to look down at her brother’s face. Even when she had become an alicorn, she was still at his height. Now she towered over him by several inches.

“I have done what you asked, your majesty,” Shining Armor said, bowing low, making his wings flop pointlessly.

Twilight suppressed a giggle. “Very good, my subject. You deserve a reward.” She reached to her side, about to slip her hoof underneath the cloak to find a bag of candy.

“Not here, Cady!” Shining Armor hissed, making a motion with a hoof.

Twilight arched an eyebrow, a slow, wicked smirk spreading across her muzzle underneath the hood. Shining Armor thought she was Cadance!

“Very well,” Twilight said, waving a hoof imperiously. “Pray lead us somewhere more adequate,” she said commandingly.

All she had to do was play the part for a few minutes, drop her spell and return to her normal self, and she would have a prank worthy of Rainbow Dash for no effort at all!

Shining Armor gave a smile at that, immediately stepping into the trees. The sound of his eager hoofbeats travelled away into the darkness.

Twilight frowned, but followed after him, tugging at her cloak when it snagged on twigs.

“Shining?” she called, brow furrowing. It was quite dark this far off the path, and even the moonlight struggled to light the leaf-littered ground.

“Shining?” Twilight called again, a little louder.

“Your majesty,” Shining Armor said, bowing with a smile.

“My subject,” Twilight said with a smirk. “I have a confession…”

“Have you been… naughty?” Shining Armor asked with a wicked smile, pressing closer.

Twilight opened her mouth to respond, her cheeks flushing at her brother’s obvious innuendo. “N-no—”

“Do you want to?” Shining Armor cut across before she could say anything else, pushing in to give her a sudden heated, eager kiss. “You are so hot like this, Cady!”

Twilight was stunned, eyes wide at the sudden kiss. She hadn’t even had time to push him away or stop him!

“You mentioned a reward,” Shining Armor purred, nuzzling at her neck and then brushing past to push down her cloak slightly, beginning to nibble and bite lightly at the leading edge of her wing.

Twilight’s wings stiffened slightly under the cloak, and she almost melted under the bites and nibbles. It was sublime. Her mind wandered for a moment, trying to conceive of where her brother had learned to do such things to wings.

Warmth rose in her face as she realised exactly where he had learned to do such things. With Cadance, the princess of love. Probably all of those times he rutted her. The blush intensified as the mental image of her brother fucking Cadance flashed through her mind. It was crystal clear in her mind. Perfect white flanks heaving as he humped deep into the princess, grasping one of her wings in his mouth, giving those maddening nibbles and tugs as he crammed inch after inch of his stiff cock deep in—

Twilight gasped, eyes widening as a hoof suddenly rubbed right up against her moistening cunny, grinding in against her slowly. It wasn’t her own cunt that her brother was rubbing his hoof against, but rather, Nightmare Moon’s. Instead of purple, it was black, with a glimmer of eager, soft pink between the pliable black lips.

“Fuck you’re hot,” Shining Armor groaned, giving a firmer rub up between her thighs, spreading some of her own gathering wetness over the soft lips of her cunt. “I’ve been wanting this all fucking day,” he growled lustfully.

Twilight’s mind snapped into overdrive. Cadance had planned this? They had sat down and planned her brother rutting a simile of Nightmare Moon? This was something they had discussed and decided upon? It was so depraved...

...And arousing.

“Sh-Shining—” Twilight started urgently. She had to make some excuse, think of some reason for her to leave. There was now no way for her to let Shining know he was rubbing his little sister’s drooling cunt. But the stimulation was driving her nuts, and each rub chased out any coherent thoughts that might have been forming. “Y-you need t-to…”

“Yes?” Shining Armor asked expectantly, biting heatedly at the side of her neck, giving a firm little rub right over her clit, making her hips jerk and lift slightly.

Twilight whimpered softly, ears splaying back heavily, her new wings stiffening slightly. Her head lowered and she quivered in delight, trying to focus. Her new angle silhouetted something far more distracting than just a hoof rubbing at her aching cunt.

Shining Armor had been anticipating this for white a while. He was already ‘aroused’. Inch after inch of her brother’s stiff cock stood proudly, visibly throbbing with anticipation at the thought of getting to screw Nightmare Moon.

Twilight swallowed thickly, staring at the outline of the throbbing length. She had seen it before, one time when she had walked into his room without knocking. But that had been years ago, before she had been interested in colts at all. She hadn’t understood what it was. But now, she definitely knew.

If she didn’t do something soon, her brother was going to cramming that entire glorious length inside her cunny.

Or maybe even down her throat…

Twilight’s mind was instantly overtaken by the image of Shining on his back, watching Cadance blowing him, pink muzzle bobbing eagerly in his lap. Maybe even holding her mane, urging her up and down…

Did Cadance swallow? Did Shining Armor hold her down as he came right in her mouth? Did she pull back and open her muzzle, extending her tongue to accept the eager spurts of her brother’s spunk?

“Well?” Shining Armor asked, smirking at her, rubbing his hoof even more firmly against her, spreading her own wetness over the mound of her eager cunt. “You look like you want this more than I do, your majesty.”

For a split second, Twilight considered staying. Saying nothing and just staying, allowing her brother to screw the facsimile of Nightmare Moon…

Immediately, a gush of her liquids spilled down from her clenching cunt, drooling over her brother’s hoof. Her heart rate increased rapidly, pounding in her ears, and she quivered weakly.

“Y-you need to… n-need to… ha-have to…” Twilight whimpered, dancing from one hoof to the other, wings stiffening heavily. “N-need to w-worship m-me… w-with your t-tongue…”

“So long as you repay the favour…” Shining Armor smirked, stepping around her eagerly.

Twilight was stunned, staring into the darkness, eyes wide, unable to believe what she had just said.

A hoof touched at her rump, and she jumped slightly as a firm pressure spread her open. She was vaguely aware of her aching cunt being spread with the firm pressure of her brother’s hoof on it, and then the tickle, and then firm grind of his tongue along with a heated exhalation, right against her inner flesh. A helpless groan left her quivering lips, and her hooves went weak. She found herself on her chest in short order, rump lifted for her brother’s eager licks at her drooling entrance.

Shining Armor’s hooves grasped at her rump, squeezing and rubbing over the firm expanse of smooth black flesh, helping to spread her open so that his eager tongue could dig into the exposed inner flesh.

Twilight whimpered in delight, her wings stiffening rapidly, fluttering lightly above her. Her cloak slipped off entirely as she pushed back against her brother’s eager licks, her hindlegs quivering and eager cunt clenching at his tongue. Tilting her head slightly to one side, she caught sight of Shining Armor’s eager erection, bobbing underneath him. Her horn lit up, and she licked her lips lewdly as a band of magic encircled the end, just underneath the swollen crown, and began to work up and down.

A heated gasp against her drooling cunny made her flush with embarassment and a certain pride. “Y-yes S-shiny… Lick me…”

“Yes, your majesty,” Shining Armor groaned, lightly rocking his hips back and forth with the pressure sliding up and down his stiffened cock, drooling a slick dribble of precum onto the ground. He returned to lapping at her with a will, forehooves now spreading her open properly so his tongue could dig right in against her depths, sending her absolutely crazy with the intense stimulation against barely-touched flesh.

Twilight caught sight of the slick dribble of his moisture, shining in the moonlight, and she was overcome with the sudden urge to taste it. She pondered on it, on how it might taste, and feel against her hungry tongue, devoting half of her mind to that while the other half was whisked away by the sublime sensation of her brother eating her out so eagerly. The magic around his throbbing length started to work up and down faster, trying to coax out more of the slick precum for her viewing pleasure.

One of his hooves lifted to rub at her clit, and she just lost it. Her entire form tensed and spasmed, and she clenched her jaw as she arched, the firm depths of her eager cunt clenching at his tongue almost urgently as she spilled a gush of moisture over her brother’s lips and mouth.

Shining Armor smirked, chuckling against her faintly, tongue slowly drawing up the length of her spasming, clenching, firm black cunny. “You taste good…” he growled, giving her rump another firm squeeze. He rose to his hooves properly again, though, slowly circling around her again, licking his moistened lips. “But I wanna see that sexy muzzle streaked with my cum…”

Twilight looked up at her brother, eyes widening, heat rising in her cheeks and wings stiffening on reflex. “W-what?”

“I want to cum in your mouth,” Shining Armor repeated with a wicked smile, stepping over top of her, letting the stiff length of his cock dangle right in front of her nose. “Your loyal subject wants his reward…”

Twilight flushed deeply, entranced by the sight of her brother’s urgent, stiffened cock right in front of her nose. One of her hooves crept down her stomach, slowly rubbing just shy of the slick, aching cunny. She licked her lips weakly. “I-I’ve got f-fangs now, S-Shiny… a-are you s—”

Shining Armor cut her off however, a powerful hoof grasping her newly-enlongated horn and dragging Nightmare Moon’s soft lips right up to the spongy tip of his stiff, throbbing cock.

Twilight whimpered softly, her nose and lips suddenly slick with her brother’s precum, the slimy substance sticking to her black fur. She licked her lips anxiously, accidentally lapping up his precum and brushing her tongue against the tip of his cock in the process.

The hot, musky taste of her brother’s precum flooded her senses, and she quivered weakly, the hoof pushing all the way back to begin rubbing urgently at her inflamed cunt.

“Fuck!” Twilight heard her brother hiss, and a pair of hooves grasped around her muzzle, tugging it upwards. “Open up for me, your majesty! Show me that sexy mouth!”

Twilight flushed deeply at the implications, whimpering in the back of her throat, rubbing almost fervently at her drooling cunny. Her muzzle opened, lips parting and tongue extending past her pointed fangs, presenting her muzzle for her brother’s intent gaze.

Shining Armor gave a low groan of delight as he peered down into Nightmare Moon’s open mouth, biting his own tongue and giving a shudder. “Fuck that’s hot…” he growled, even as he tugged her muzzle down and slipped his cock directly into her mouth without any warning.

Twilight’s eyes widened, and she quivered in surprise, giving a muffled sound around the thick cock tip spreading her jaws. The heated taste of her brother’s arousal flooded her senses, and she shivered once more, rubbing urgently at her drooling, spasming cunt.

“S-suck on me, Cady…” Shining Armor whimpered needily, tugging at her muzzle to encourage her to move. “N-need to cum in that sexy fucking muzzle.”

Flushing furiously, Twilight closed her lips around the tip of his cock, giving a slow, gentle suckle. Her fangs grazed along the bottom and top of it, but there was just no way to avoid brushing the ivory points over him with how much he spread her jaws. Her hoof rubbed insistently at her clit, sending shocks of pleasure through her system as she began to slowly grind her smooth, sinuous tongue right along the underside of her brother’s thick cocktip.

Shining Armor groaned faintly, giving a slow roll of his hips against her muzzle, working the fat head of it against her smooth tongue, drooling musky precum directly onto her tongue.

Twilight whimpered softly, quivering in another miniature orgasm as she tasted her brother’s eagerness on her tongue. With a wanton groan, she pushed a little bit further down him, eyes slowly opening to stare up at him.

Groaning faintly and rocking back and forth, Shining Armor gyrated the eager stiffness of his cock within her muzzle, grinding it over her tongue. He glanced down at her, catching her expression, making eye contact.

Twilight looked up at him, lightly swirling her tongue along his underside, before giving a toothy, eager smile and beginning to suckle at him eagerly.

Shining Armor almost lost it right there, a hoof grasping her wispy mane with a long, quivering groan escaping his muzzle. “O-oh f-fuck… like that… yes…”

Twilight hadn’t expected her brother to be quite so vocal or use such crass language… but she liked it. Every eager twitch of his throbbing cock and every dribble of precum that graced her hungry muzzle with its presence just made her rub at her aching cunt all the more eagerly.

“Oh… fuck…” Shining Armor groaned, taking a step forwards and starting to hump almost urgently into her mouth. “I-I’m gonna cum Cady…”

Twilight flushed again, eyes widening slightly. She had been intending to pull back, to let him spill on the ground, but with every throb of the eager stallion flesh splitting her muzzle open, with each grind and push of his hips into her willing mouth, she started to like the idea of tasting him all the more.

Flushing furiously under her magically altered black cheeks, Twilight leaned forwards and swallowed more of her brother’s flaring cock. She pushed down him, bobbing eagerly, feeling his tip thickening, swelling and spreading the back of her jaws, almost buried in her throat.

“Ngh… f-fuck!” Shining Armor hissed, grasping her muzzle in either hoof, starting to hump urgently into her mouth.

Twilight’s eyes widened, and she shuddered, pushing her nose towards the base of his cock, gagging faintly as his spongy tip pushed up against the back of her throat with each of his eager humps. He was already starting to tense and thicken further, and she had mere moments to change her mind and pull back, or get a fresh load of her brother’s essence deposited right in her mouth.

And then it was too late. The cock throbbed hard, and then sudden volleys of her brother’s gooey, sticky spunk were being pumped directly into her mouth. Again and again the heavy spurts escaped him, firing in sticky ropes right across the back of her throat.

A wanton groan left Twilight’s stuffed muzzle, and she almost choked as she shuddered her way through a minor orgasm at the sensation and taste of the rich, potent spunk flooding her senses.

Again and again she swallowed, almost urgently suckling at the throbbing cock as it continued to fire directly into her hungry muzzle. Shot after shot of the rich spunk filled her mouth, until it was leaking from the corner’s of her lips and down over her chin.

With a gasp for air, Twilight tugged back, panting hard and quivering, cheeks flaring with heat as the last few sticky ropes of her brother’s urgent cum splattered over her black cheeks, standing out starkly against her black fur. A thick, sticky waterfall of stallion spunk drooled from her open mouth, coating her tongue and the inside of her muzzle.

Shining Armor stared down at her, giving a low groan of delight and slowly collapsing onto his rump.

Twilight pulled back, blushing furiously, swallowing thickly and giving a faint, helpless groan at the taste still flooding her senses. It was everywhere! Completely inescapable. Her mouth, her tongue, coating over her teeth, her lips, her chin, and with several ropes of it warm and heavy on her face! It was disgusting, deplorable, repulsive, and easily the single most arousing thing she had ever partaken of.

“Sweet Celestia… that was so good, Cady,” Shining Armor said, grinning down at her. “Do that thing…”

“What thing?” Twilight asked, voice muffled by the not-insignificant amount of spunk still sticking to every surface of her mouth.

“That… uh… thing,” Shining Armor said nervously, making a motion with her hoof. “Y’know... where you open up for me…”

Twilight blushed again, and, thinking about just how much of a freak Cadance was, she lifted her nose and opened her muzzle, tilting her head slightly so that the moonlight could shine on her mouthful of her brother’s spunk. She extended her messy tongue as well, laying it between her cum-stained fangs.

Shining Armor gave a low whimper of delight. “Fuck… I should have brought a camera…”

Twilight shuddered at the implications of that, before closing her muzzle and swallowing thickly to clear it. The warm, gooey mess of Shining’s spunk slid down her throat, and she quivered, her wings fluttering slightly as it hit home exactly what she had just done.

“I… I need to go. Clean. Clean up. Need to clean up,” Twilight said jerkily, motioning with a hoof.

“Go and get cleaned up, Cady,” Shining Armor said with a smile, inclining his head. “I’ll see you back in Canterlot.”

Twilight nodded, rising to her hooves and then galloping away into the darkness.

Twilight sighed faintly, stretching her wings a little as she clambered up into the carriage bound for Canterlot. Technically, she was supposed to have slept in the Canterlot castle, but after getting a mouth—and face—ful of her brother’s spunk, she had retreated to Ponyville. A sleepless night in the library rife with vigorous masturbation, and she was back to her usual fang-less purple self.

But that still left a few unanswered questions… no doubt Shining Armor would realise he hadn’t screwed Cadance the previous night. It was only a matter of time before awkward questions were asked. But Twilight would just say she tried to fly, fell, injured herself, and spent the rest of the time alone at the library, nursing her wounds. Her hoof was certainly sore enough to convince anypony that she had sprained it. But that was a masturbation-induced injury.

The carriage started to move forwards, and as it did, the door opened, and Shining Armor barged in, kicking the door closed behind him and locking it, pulling the blinds for privacy.

Twilight’s eyes widened, and she felt her cheeks warming, her wings giving an anxious little flicker. “Oh h-hi Shining,” she stammered, trying her best to keep her voice level and nonchalant. “Fancy seeing you here this early.”

“Twily,” Shining Armor asked, eyes narrowing slowly.

Twilight suddenly felt like she was being interrogated.

Shining Armor stared into her eyes, seemingly looking right through her, examining her very soul. “The spell you used to make Cadance look like Nightmare Moon. Did you use it on anypony else?”

“What? No. That would be horribly irresponsible.” Twilight spoke before she thought, and then blinked once, realising that she was talking herself into a corner.

Shining Armor frowned deeply, staring at her still. “Where were you last night? At the start of the night?”

“In pain,” Twilight said coolly. “Tried to fly. It didn’t work. Hurt my hoof and limped all the way to the library.”

“Which hoof?”

“My right hoof,”

“Well when you came in here, you were favouring your right,”

“I mean my left hoof,” Twilight corrected, snorting once. “Why are you giving me the third degree?”

“Something happened last night and I want to get to the bottom of it,” Shining Armor stated flatly. “Somepony was Nightmare Moon, and I ran into them. They tricked me into thinking they were Cadance and I might have divulged information to them that I want to keep private.”

“Divulged information?” Twilight asked innocently enough. “What kind of information?”

“That’s immaterial,” Shining Armor said, waving a hoof. “So, did you see anypony else dressed as Nightmare Moon around?”

“A few,” Twilight said carefully. “She’s a popular costume.”

“This was a full-body makeover, like your magic,” Shining Armor said with a wise nod.

“How could you possibly know that?” Twilight asked bluntly.

Shining Armor’s cheeks flushed imperceptibly. “I have my ways.”

“Did you kiss her?” Twilight asked in a hushed tone. “Is that why you’re so determined to find them?”

Shining Armor stiffened slightly, before deflating and nodding once. “Yeah. I kissed her. Whoever she was. Cadance would kill me if she found out.”

And that’s not even the half of it, Twilight thought to herself, a wry smile spreading across her features. “Don’t worry, we’ll find out who it was. Ask everypony who was on the fringe of town if they saw anypony come wandering in?”

Shining Armor’s ears perked up at that, and his eyes once more found her own. Twilight suddenly felt as though she had made a mistake. “Why… on the edge of town?”

“Well… somepony would have to go through the fringe of town to reach the interior of the town,” Twilight said blankly, confused.

Shining Armor nodded once, looking down at the floor of the carriage again.

Twilight assumed she was in the clear, and tried to still her beating heart.

“...I never told you that it happened in the forest,” Shining Armor said quietly.

Twilight’s eyes widened, and she quivered slightly, a hindleg kicking reflexively. “N-No. S-see, you said that i-it happened and I a-assumed because of verbal queues that y-you meant—”

Shining Armor held up a hoof to halt her stammered, incoherent rebuttal. “Why.”

Twilight was taken aback, her ears splaying and wings giving an uncertain flutter. “W-what?”

“Why?” Shining Armor asked again, his expression blank.

Twilight was confused. She had expected yelling, tears, anger, disgust, outrage… but this was just… emotionless questioning.

“W-well… I-I was going to surprise you…” Twilight admitted, frowning deeply and chewing at her bottom lip, cheeks flushing deeply. “I was going to prank you. Just play along long enough for you to think I was Cadance, and then I was going to surprise you, and it would have been a prank worthy of Rainbow Dash… b-but then…” She made a motion with her hoof in the vague direction of her lower body. “A-after you pushed your hoof up between my thighs I couldn’t tell you it was me! T-that would have been awkward…”

“More awkward than blowing a load in my sister’s mouth?” Shining Armor asked flatly, glowering at her. “What were you thinking, Twilight?”

Twilight’s ears lowered, and she bit her bottom lip again, tail giving an uncertain flick back and forth. “I-I wasn’t thinking. Or I w-was… Thinking about you and Cadance…”

Shining Armor blinked at that, his cheeks flushing slightly. “Well that… that was hardly… I don’t even know what to say, Twilight.”

Twilight looked up at her brother, ears pinning and wings drooping slightly. He was glowering at her, hooves crossed, looking incensed, confused, and most of all, awkward. What could you even say to a relative after you were tricked into literally fucking their face?

With a slight frown, Twilight looked back down at her hooves, and then, she made the one decision that could dispel the awkwardness before it became near-permanent.

It was time to double down.

“Did you enjoy it?” Twilight asked quietly.

Shining Armor blanched at that, eyes widening.

“Did you enjoy it?” Twilight asked again, slowly slipping off the seat on her side of the carriage, and moving to sit on his own side. “Does it… does it excite you to have had your little sis b-blow you?”

Shining Armor’s eyes went as wide as dinner plates, and he sucked in a breath, giving an anxious quiver. “W-what are you t-talking about?” he stammered, his cheeks beginning to warm noticeably.

Twilight felt herself flushing as well, but she pushed through it recklessly. “I-I masturbated so hard last night… I rushed home d-dripping your…” she bit her bottom lip, unable to bring herself to name it. “Y-your stuff, and I rubbed myself absolutely silly remembering the taste of it… and the feel of it spilling into my m-mouth…”

“S-stop…” Shining Armor whimpered, his own ears splaying back, a hindleg twitching, kicking slightly.

“It made me so hot, Shiny,” Twilight whispered softly, leaning closer to her brother, close enough to nibble heatedly at the base of his ear. “I-I was disappointed that I didn’t stay long enough that you could f-f…” She bit her bottom lip again, pushing a hoof into his ‘lap’ to rub lightly at the growing length of stallion cock. “That you could fuck me.”

Shining Armor gave a gasp. “Oh f-fuck…” he whimpered, arching slightly and squirming in his seat.

Twilight gave a slight smile at him, nibbling at the base of his ear lustfully, her hoof stroking and coaxing at the cock. “I-I know you enjoyed it, Shiny. And if… if you want me to…” she gave a pointed rub against the crown of his stiffening cock with her hoof. “Just… just say the word.”

A soft whimper left the stallion, and he quivered helplessly.

“Did you know that I orgasmed?” Twilight asked softly, looking up into his eyes earnestly. Shining Armor made eye contact, held it for less than a quarter of a second, and then looked away, blushing hotly.

“W-when you… when you c-came in my mouth,” Twilight stammered, licking her lips anxiously. “It tasted and felt so good that I came…”

With a faint shudder, Twilight leaned over, meeting the now-stiff tip of Shining Armor’s cock with a soft, delicate kiss, right against the very, very tip.

Shining Armor bit his tongue, eyes wide, watching his little sister kiss the tip of his cock. “T-Twily…” he whined.

“If you ask me to stop, I will,” Twilight panted, her eyes misting slightly as she inhaled the scent of her brother from point-blank range. She nuzzled down past the stiff length of stallion cock, and nosed in against the base, pushing against his balls. Her soft little pink tongue trailed along the underside of his cock, working right up to the very tip of it, capturing the dribble of precum that was already appearing.

“F-fuck!” Shining Armor swore, unable to tear his eyes away from the sight of his little sister toying with his stiff, eager length.

Twilight groaned faintly, nibbling at the edge of his thick tip, letting her blunt teeth work over it, even as she pushed a hoof between her own thighs, beginning to rub at her once-again drooling cunny.

Shining Armor glanced to where her hoof was, and then back down to where she was amorously nibbling and licking at his cock. He gave a pathetic whimper, his cock flexing slightly and spurting a droplet of precum so powerful that it spilled up onto his chest.

Twilight groaned faintly, crawling up his form and then leaning in to lick the precum from his pristine white chest fur. She sandwiched his cock between them, making sure to sit right against the base, letting the wetness of her aching cunt grind right above his heavy testicles.

“T-Twily…” Shining Armor whimpered, lifting a hoof to touch at her shoulder before returning to clenching it at his side. “T-this is so f-fuck wrong!”

Twilight nodded urgently, climbing further up his form, standing with hindlegs spread on either side of his haunches, her smooth purple pussy hovering right over the fat tip of his cock. She leaned forwards to kiss her brother heatedly, tongue pushing against his lips before sinking between and meshing with his own.

After a few moments, she pulled back, carefully aligning their bodies so that she could push the heated mound of her drooling cunny right against the swollen tip of his cock. She slowly gyrated back and forth, staring down at him, biting her bottom lip. “I can stop if you want…”

“F-fuck…” Shining Armor whimpered, squirming underneath her, his ears splaying back heavily. “This is too wrong… this is bad…” he whined, even as he wrapped both powerful forehooves around her rump and then shoved her downwards, sinking inch after inch of thick cock deep inside her without warning.

Twilight almost screamed, stifling the sound with her hoof, eyes clenching closed as she felt her brother’s stiffened cock buried inside her. The thick tip of it was spreading her so wide, and she was completely unprepared for the rush of sensations.

Gravity dragged her down her brother’s cock, forcing inch after inch after glorious inch inside her, spreading her further with each moment until she managed to get her hindhooves under herself and halt her downwards motion. She panted hard, forehooves on his shoulders, nose pushing into the side of his neck. “M-mnnf… S-Shiny…” she whimpered.

Shining Armor only responded by grasping her hips and using his surprising strength to lift her up and then sink her back down.

Twilight really did scream this time, but Shining Armor quickly caught her muzzle in a heated kiss, locking her lips against her own. His hooves wrapped around her middle a little bit further, pushing her rump down with a firm pressure just above the base of her tail, working her up and down the amazingly stiff cock.

“Fuck!” Twilight snarled, surprising her brother with the outburst. He smirked slightly, panting and grasping her rump with both hooves, lifting her all the way up and then letting gravity drag her back down over him.

Twilight’s hindhooves scrabbled for purchase, but she tilted too far back, losing her balance entirely and ‘falling’ into her brother’s lap, sprearing herself on every single delicious inch of his cock. She quivered, shuddering atop him as he crammed her entirely full, his tip jolting up against her cervix with a soft impact, making her jerk like she received an electric shock.

“I-its s-so b-big…” Twilight whimpered, looking down at her stomach, expecting to see some kind of bulge. The smooth line of her stomach was unbroken by any bumps, which perplexed her. How could anypony take that much cock without breaking?

“Y-you’re f-fucking tight, Twily,” Shining Armor murmured against her ear, his cheeks reddening further.

“S-so good,” Twilight murmured, biting at the side of his neck lustfully, pushing hooves against his chest for balance as she gathered her hooves underneath her. She slowly rose upwards, stretching up until the tip of his cock almost left her clenching cunt, only for her to relax her legs and slam herself downwards with a squeal of delight.

Shining Armor gasped and cried out in delight too, quickly leaning up to kiss her again, stifling the groans of delight leaving the siblings.

Twilight started to bounce enthusiastically in his lap, sliding up and then shoving down over his cock again and again. Each impact crammed her entirely full of her big brother’s cock, spreading her deliciously wide. She could feel the slick warmth of his precum drooling across her insides, helping to lubricate their union, even though she was producing enough moisture by far.

“Mnnf… h-hah… s-so big…” Twilight whimpered into her brother’s mouth, before kissing him urgently again. “I-I’m g-gonna orgasm S-Shiny…”

“W-wait…” Shining Armor groaned, pushing her hips down over him to the very base, cramming his little sister full of every inch of his throbbing meat, and holding her there with his powerful hooves, panting hard. He made eye contact with her, blushing furiously. “T-Twily… I-I’m getting close.”

“Good…” Twilight groaned, pushing powerfully against his chest with her forehooves, freeing up enough motion to begin bouncing on him in a frenzy again.

“Oh sweet C-celestia…” Shining Armor whimpered, staring up at the ceiling in a daze, his horn starting to glow.

Twilight pushed her nose into his neck heatedly, bouncing on him over and over again, her heated depths clenching around him harder and harder with each passing motion. Her spread purple cunt visibly clenched around him, slicking the entire length of his cock with her moisture as she started to tense. Her forehooves grasped weakly at his muzzle as her own horn began to shine, urgently trying to get him to face her.

Shining Armor looked down at her in a haze, only for her to kiss him urgently, shoving her muzzle hard against his own with a wanton, muffled groan. Her hips began to rise and slam down harder and faster, urgently fucking her brother to an intense orgasm.

A particularly powerful shove of her hips rocked their bodies, and their horns touched.

Twilight stiffened, eyes widening as the purple light from her horn found the blue light of Shining Armor’s, and a flash of brilliant gold arced between them.

They both convulsed, screaming their delight into each other’s mouths, even as they were both pushed instantly over into tumultuous orgasms.

The heated pink depths of Twilight’s clenching cunt squeezed in earnest around Shining Armor’s spasming cock, clenching around the base in a rhythmic motion that travelled upwards, milking his throbbing length.

Shining Armor grasped his little sister’s hips, shoving her right down to the base, grinding up into her and snarling into her mouth as the entire length stiffened and jerked. His flaring cock was crammed up against her cervix like a plug deep inside her, spreading her deepest reaches open around him. The first heavy burst of spunk splattered directly across her deepest barrier, inundating her clenching pink depths in a flood of gooey white.

But Shining Armor was still humping up into her jerkily with each urgent burst of his spunk that splattered deep inside. Twilight was rocked up and down, screaming into his muzzle in delight as she clenched and milked around him. Each time her hips came down, a fresh burst of his spunk was fired up into her hungry cunt, and a slick dribble of it was forced out around their union, drooling from around the base of his throbbing, jerking cock.

Twilight whimpered into her brother’s mouth as he filled her to the absolute brim, and she shakily lowered herself down into his lap, splaying across his heaving chest, her wings laying limply over both of them. “O-oh… S-sweet Celestia…” she groaned hazily.

Shining Armor groaned faintly against the side of her neck, wrapping his hooves around her, slowly stroking a hoof up and down her wings. “I-I agree…”

“T-that was... “ Twilight trailed off, giving him a significant look, waiting for him to finish the sentence.

“A mistake… A horrible… disturbing mistake…” Shining Armor panted, grasping her rump with a hoof, looking past to where he was buried deep inside, his spunk slowly drooling from between their bodies, making a mess of them both.

“Y-yeah… a mistake…” Twilight murmured.

Shining Armor snorted once, capturing her muzzle in another kiss, giving a soft sigh and then staring into her eyes for a long moment. “A mistake that… I think I’m going to end up making again…”

“Are you sure?” Twilight asked, trying not to sound too hopeful.

Shining Armor flushed slightly, nodding. “I-I’ve never came like that before… I-I would like to do it again sometime…”

“Next weekend?” Twilight asked breathlessly, eyes widening slightly.

Shining Armor bit his bottom lip, looking away. “I-I’m due in town on Friday for a guard meeting… W-we could share a carriage or something…”

Twilight nodded earnestly, leaning in to kiss him heatedly again, squeezing her big brother with a wide grin.

“It’s a date!”

Shining Glory

By Shakespearicles

“Twilight!” Princess Cadence greeted the purple mare entering her throne room. “I’m so glad you could make it!” Twilight trotted merrily into the waiting hooves of her old foalsitter. No matter what else happened around them, she knew she could always take comfort in her reassuring hugs. And by the sounds of things, she was going to need it.

“I received your urgent message, Cadence. I got here as fast as I could.” Twilight said. “But you didn't specify what the problem was.” Cadence looked to either side of them. Her guards stood vigilant, eyes forward, unflinching. But they could not help but overhear the conversation.

“Follow me Twilight.” She said, stepping down from her throne. “Let us go speak somewhere more private.” Twilight followed her through the halls of the Crystal Palace. The structure had an overwhelming beauty beyond words. But if Twilight had to pick one, it would be ostentatious. Each window bore a skyline view of the whole of the empire. The land glistened with tiny lights in the late evening. Others windows were filled with exquisite stained glass memoriams to historical events a millennium ago. Elsewhere the walls were adorned with lush tapestries.

The guards following took up their posts at either side of the entrance to the royal chambers. The two princesses stepped inside, closing the door behind them. Twilight had never been in their new bedroom after they’d moved to the Crystal Empire. It was just as decadent as the rest of the castle. The bed was enormous. And above the headboard was a replica stained glass window to the one in Canterlot Castle. It depicted Twilight’s brother, Shining Armor, and Princess Cadence using the power of their love to repel the changeling invasion of Canterlot.

“So where is Shining?” Twilight asked. Cadence gave her a nervous look and called a spell to her horn, causing it to glow blue. The doors shimmered for a moment.

“Guards, come in here.” Cadence called out. There was no response. “Guards help! I’m being murdered!” She screamed. Twilight panicked. Still there was no sign of anything happening outside. “Sorry Twilight. I didn't mean to scare you.” They both relaxed. “It’s just that, this is a sensitive issue and I want to make sure that there are no prying ears.” She settled onto her bed as Twilight listened intently from the sofa. Whatever this was, it was a big deal and it had something to do with her brother.

“Twilight, I’m so scared.” She said. “Your brother- Every week, at some point he just vanishes. He leaves the palace and refuses a guard escort. He goes out into the night where anything could happen.”

"That's- that's awful! Doesn't he know what he's doing to you? Making you worry like that? Have you talked to him about it?"

"I've tried." She said, on the verge of tears. "He said he gets bored of being stuck in the palace all the time and he needs his personal space." She said. Twilight nodded. She could understand that at least. "But I wish he would take a couple of guards with him. Who knows what could happen?"

"Cadie, I've seen him get into a scrape. I know he could handle himself in a fight."

"Oh, I know." Cadence said with the slightest smirk that faded as quickly as it appeared. "But even if he insists on going alone, I wish he would at least tell me where he's going." Twilight passed a handkerchief to her. "It's awful. He disappears for hours at a time and then just shows up like it's nothing. But I know it's not nothing." She paused, wiping her eyes. "Twilight, I want to trust him. But I need the truth. I need you to follow him. Find out what he's doing for me. Please."

"But why me?"

"Twilight, I don't know who I can trust to keep this matter a secret. I'm afraid that if he's doing something... illicit, it would destroy his reputation. The ponies need to believe in their leaders. You know how fast rumors circulate through the barracks." Twilight nodded. "And more than that, after you told me about your exploits about sneaking into the Canterlot Archives undetected... I need a pony who understands the concept of subterfuge, a subtlety that my guards seem to lack." Cadence let her words hang in the air, awaiting a response. Twilight considered what was being asked of her.

"Okay. I'll do it."

Twilight Sparkle sent home a notice of an extended leave of absence. The rest of the week, she studied what little information Cadence and the guards could offer regarding Shining's behavior. She stayed hunkered down in one of the small guest rooms, her presence known only to Cadence and a trusted handler to bring her some necessities. She wouldn't have to wait long. It was Tuesday. Shining had done his best to make his little constitutionals seem random. But she had discerned a pattern. If his modus operandi held, tonight would be the night. Twilight donned her cloaked disguise and laid out her tools for the night. She had no idea what he might try to do. She'd need everything available at her disposal. She put her ear to the door, listening for a sign.

"Hey, Iron Wing, I'm just gonna hit the restroom before I lay down for the night. Go ahead and move your post to the bedroom door." Shining said, dismissing the guard. This was it, she decided. He had a moment unobserved to make good his escape. She dove out of her window, spinning in air, facing the wall from the outside. She fired off a couple of grappling hooks from her belt rig. As she fell, she arched toward the crystalline wall, skittering to a halt, standing sideways. She walked up the wall as she slowly reeled herself upwards.

Twilight replanted a hook to her left and swung like a pony pendulum, running across the wall. Her silent hooves came to a stop just above the window of the restroom. Twilight braced herself, hoping she was correct and that she wouldn't find him inside sitting on the porcelain throne. She rolled backwards and lowered herself down. The room was empty. He'd escaped and it wasn't out the window like she'd suspected. She kicked off of the wall and swung back toward the window, kicking her hooves through.

In an instant, the door to the bathroom was kicked in. The guard in the hall checked to see what the broken glass commotion was, only to find Shining Armor missing and an assassin cloaked in black who'd clearly thrown the prince out of the window to his death.

"ASSASSI-" The guard was cut off as Twilight struck him in the face with a thrown burst-pouch of sleeping powder, knocking him unconscious. She knew she had only seconds to spare before reinforcements would arrive. She ditched her grapple harness and felt around the walls of the room looking for any kind of button, switch or lever. Nothing. But then, in a flash of serendipity, she lifted the cover to the toilet tank. Inside was a fulcrum release! She pulled the lever as the wall behind the toilet opened in eerie silence. She replaced the cover on the tank and slipped inside the alcove before the wall closed behind her.

She didn't want to give away her position by calling light to her horn. She pulled from her bag a pair of night vision goggles. When she was first tasked with the assignment, she'd sent home a list of things she'd need for the task with her notice of absence. As they warmed to life, the pitch blackness was revealed to her in an eerie green image. It was a narrow stairway following a set of pipes. Twilight realized that she was in and old service access point to the palace's wet wall. Twilight quickly made her way down the staircase. The padded stockings silenced her hooves on the hard crystal steps. The confined space gave her little in the way of visibility.

She rounded a final turn and froze in place. She'd caught up to him faster than she'd planned. He stopped moving and turned around. Twilight stood there, stalk still, as he peered into the pitch black darkness right at her. She held her breath and prayed that he couldn't hear her heart pounding in her chest. He reached out into the darkness at her where he felt the presence. She leaned away, narrowly avoiding his hoof by a hair's breadth.

He waited a second longer before turning and quickening his pace down the stairs. After he was sufficiently far enough away, leaving fast and loudly, Twilight took a panicked gasp of air that she'd been holding. She followed after him, keeping mindful of the distance to the sound of his hooves.

At the bottom she heard the grinding sound of stone on ancient stone. She carefully peered around the corner as he slipped through a second false wall out into a large hallway. Twilight slipped through after him just before the wall closed behind her. From this side, there appeared to be no other way to open it. The hallway she now stood in turned out to be a main waste line for the city. A sewer.

Shining had already taken off down one of the elevated walks beside the river of filth. Twilight abandoned her search for a means to reopen the wall. One-way trip tonight. She thought to herself moving after him. He stopped at the foot of a ladder and opened his bag. Twilight watched him throw on some plain peasant's coverings and head up the ladder, opening the cover to the street above.

Twilight held her place for just a moment. She couldn't afford to lose him now, but she couldn't risk him seeing her open the cover behind him either. The instant that the cover was closed She ran to the ladder and teleported herself high above the street. Her wings burst out through the velcro closings putting her into a controlled glide as she watched him move below her in the darkness. She lofted down to the rooftop behind him. "Where are you going?" She wondered.

He bobbed in and out of alleyways, weaving through different streets, actively avoiding the street lamps. Twilight leaped from one roof to the next. She didn't know the empire's layout well enough to make any kind of prediction as to where he was going. He trotted down a particularly narrow alley. About halfway in there was a single, unmarked door. Outside stood a rugged stallion with large sunglasses, despite it being night. Shining gave the pony a pouch and knowing nod and stepped inside when he opened the door for him. Twilight quickly surveyed the perimeter of the structure. While she did, a crystal pony walked into the building in much the same manner as Shining. There was no other way in or out it seemed. So now that she knew the only way he could go, she pondered her next move.

Twilight chose the direct approach.

She ditched her extra equipment on the roof and lofted down to the ground level around the corner. She tried her best to seem casual as she walked up to the door giving the pony a nonchalant and tried opening it.

"Whoa there. Cover?" He put his hoof out, looking at her. He noticed that she was a mare under her hood. "Oh, new talent? Go on in." He opened the door and waved her through. She still had no idea what was going on. She kept her eyes peeled for Shining but he was nowhere to be seen in the small lobby.

"Oh there you are." A slender stallion behind the desk said eyeing the mysterious mare. "Um, head down to..." He flipped a page on his clipboard, "Uh, head down to booth three." He instructed, pointing to the hallway to the right. Twilight wasn't sure who she was supposed to be to these ponies. She hesitated a moment. The stallion let out an irritated huff. "Down the right hall, third door on the left! Got it, Missy?" Twilight just nodded, keeping her face hidden under her bangs as she headed past him. "Dumb fillies. Gotta explain everything." He groaned behind her.

The doors on the left side of the hall were clearly marked one through six. She tried the knob of the door with the number three on it. She pulled it open and looked inside. It was a plain room, dimly lit, and no larger than a big closer. In the middle of the floor was a low sitting stool. On the far wall as a hole slightly smaller than her hoof. She stepped inside and closed the door behind her. This was where she was told to go. She could find out as much as she could by just playing along for now.

She sat down and tried to look through the hole. On the other side was a small room, just like hers. But there was nopony in it. Inspecting her own room She flipped a small, hitherto unseen switch to see what it did. The light in her room turned red. The door in the opposite room swung open and the crystal pony from outside stepped in.

"About time." He groaned. She watched him rear up and then something jammed her in the face. She almost fell back off of her stool. She almost couldn't believe it, thinking she was seeing things. But there it was. The crystal stallion's penis was sticking through the hole in the wall at her. She heard a banging on the wall. "Come on lady, it ain't gonna suck itself!" He said through the wall.

"Wha!? N-no I I can't!" Twilight babbled.

"Oh what the hell?" He complained. "If I wanted that shit, I woulda stayed home. Now get to work!" He ordered. She watched it bob at her, demanding her attention. In a panic, she teleported out onto the roof of the building. She sat there, hyperventilating on the shingles. She was still trying to wrap her mind around what she'd just witnessed.

"I can't believe that my brother, a married stallion, would go to a sleazy place like this to- to-" She threw up on the tile. She didn't know what she was going to tell Cadence. But she knew that she needed to confront him about this. She gathered her composure and waited on the roof across from the entrance. Another stallion walked in after a few minutes. A different one exited a short while after that. Then she recognized the peasant disguise that Shining was wearing.

Predictably, he made a general route back to the palace. About a block away, he opened the lid to the sewer he'd escaped from and stuffed his disguise into his bag, dropping it to the bottom of the ladder and closing the lid. Lastly, as though he were just out for a stroll, he waltzed up to the guards at the main entrance. Instantly recognizing him, they let him through.

"Well, that answers that." She muttered, teleporting herself back up to her room.

"And then what happened?" Cadence begged excitedly. She was in the middle of debriefing Twilight the next morning in her soundproof bedroom.

"I followed him out of the sewer and then..." Twilight hesitated. "Then he gave me the slip." she lied.

"Oh."

"Don't worry, I'll find out for sure next time, now that I know how he's getting out of the palace."

"So where exactly is this secret door?" Cadence asked. Twilight bit her lip.

"I... shouldn't say just yet. It could compromise the entire plan." She lied. She didn't like lying to Cadence. But she found it becoming more and more easy for her to do it. "Besides, I think I can solve the root of it before too long." She said, unsure if that was a lie as well or not. "Now if you'll excuse me..." Twilight jumped out of the window, gliding down to the front entrance of the palace.

"Halt, who goes there- Oh, Princess Twilight!" One of the guards addressed her.

"Yes. It is I." Twilight said, feigning a haughty demeanor. "I have decided to make an unofficial casual visit to the Crystal Empire. Be sure to inform Princess Cadenza of my arrival. And I require an immediate audience with the Prince as well."

"Yes Ma'am!"

"You certainly know how to make an entrance. Are you sure this princess thing isn't going to your head?" Shining asked. Twilight looked at him from across the table. She'd requested a brunch meeting with the prince on the palace balcony. Once the food was served, the staff left them to their privacy as per her instruction.

"I'm just trying to fit the role." She said.

"I know what you mean. I've been doing it even longer than you and I still haven't gotten used to it." He said, taking a bite of his muffin. "Always having handlers and guards following you everywhere, serving on you. Then there's the publicity. I can't go anywhere without being hassled. I just wish-"

"That you could get away from it for a while?" Twilight finished.

"Yeah exactly." He said. "But it's hard, you know?" He frowned. "And Cadence isn't helping things with her being..."

"What?"

"No I, I shouldn't talk about her. It isn't fair."

"Did she do something bad to you?" She asked.

"No, it's nothing like that." He said quickly. "It's just, it's personal."

"Shining," Twilight put her hoof on his, "I'm your sister. And this is clearly something important to you. And if it's important to you, it's important to me. And so what if it's personal? We shared a bedroom until I left for magic school. Remember when you had your first wet dream and I needed to help you wash the sheets so Mom and Dad wouldn't find out?" She asked. Shining nearly choked.

"I can not BELIEVE you remember that!"

"My point is, whatever the problem might be, it's okay. I'm just trying to help. I'm not going to judge you." She said. He looked in her eyes. He could tell that she was sincere.

"Oh my gosh." He groaned. "Okay fine. But you need to swear that this stays between me and you."

"Of course."

"Okay, um... you know how married ponies, um when they're in bed, they do... stuff?"

"Shining, I know what sex is. Don't treat me like I some stupid foal." She shot back.

"Right. Sorry." He blushed. "Okay, so you know how married ponies have..."

"Sexual intercourse. The term you are searching for is sexual intercourse. Or sex for short. Some even prefer rutting. Shall I go on?"

"Right. Sorry. Again. So you know how married ponies have sex?" He asked.

"Yes. I believe we've established that." She deadpanned.

"Yeah, well... we don't." He muttered. Twilight blinked for a second. Certainly there was more to the statement. Was there a punchline that she'd missed? She was usually so good at getting jokes, which is what this surely must have been. She replayed the statement in her head. No, nothing about it was funny.

"Wa- wait, what?"

"We don't have sex." He repeated.

"But- that doesn't even make sense." Twilight stammered, still trying to get her head around the concept. "Isn't she the Princess of love?"

"You know it's funny you say that because I said the exact same thing. But she said that it just meant that I was another ignorant stallion."

"She can't say that to you!" Twilight fumed.

"Easy now." He tried calming her. "She was sort of right. She explained that she was the Princess of Love, not lust."

"Well I get that, but I mean come on, Mom isn't the Princess of Lust and she still has sex."

"Really Twi? That's the first example you go to?"

"Well, Shining, when you say never, you mean like never ever?"

"Our wedding night, our anniversary, and my birthday."

"Oh."

"Yeah." He groaned.

"Well, can't you, you know, take care of things yourself?" Twilight asked making a jerking motion with her hoof.

"Oh believe me, I did at first. But I mean come on! I made a commitment up on the altar. I should at least get something out of it?"

"Do you not get anything out of it?"

"Twi, you're making me feel worse about this than I already do."

"Oh, sorry."

"I mean yeah, of course I get plenty from our marriage. The rest of the time it's great! We laugh, we play and cook and cuddle and kiss. But it's just that one thing. It's like the whole idea of sex just repulses her."

"That is just... not at all like I thought she'd be." He arched an eyebrow at her. "I mean I figured that she'd at least be open to things. Are you sure she's not gay?"

"Pfft! I wish! That'd sure explain a lot but no, unfortunately. She just has no drive at all." He sighed. Twilight looked down at her hoof on his and then back up at him.

"Shining, I'm not gonna lie to you. Cadence actually asked me to come here to talk to you about you disappearing some nights." He didn't respond. "Does it have anything to do with your marital problem?" She asked. He didn't flinch. "Shining? Are you having an affair?" She asked, knowing full well that he was not. At least, not in the classical sense of the term.

"Is that what she thinks?" He asked. There was no defensive or accusatory tone to the question. It was as neutral as if he were asking the current time.

"She doesn't know what to think, to be honest." She stirred her tea. "But given what you've told me, I suppose she shouldn't be surprised if you are."

"I'm not." He said immediately.

"Well, that begs the question." Twilight began. "What are you doing?"

"Just- relieving some stress. Blowing off some steam, you know?"

"Look, Shiny, if you don't want to tell me what it is you're really doing, I'm not going to try to force it out of you. I respect you too much for that." Twilight spread her forehooves open in front of her. "But I've got to tell Cadence something." Shining stared out over the balcony.

"Tell her..." He looked back at Twilight. "Tell her not to worry. Tell her I love her." Twilight picked up the napkin and wiped her mouth before crumpling it and tossing it on her plate.

"You should tell her yourself." She said, excusing herself from the table.

"I do. Twilight? I do! Twilight!" he called after her.

"So did it work?" Cadence asked excitedly on her bed. "Did you get him to tell you what he was doing?" Twilight settled back into the sofa.

"Not exactly. This situation requires a bit more cunning than such a blunt approach." She said. Cadence looked disappointed. "But the clues are starting to fall into place." She added. "I just need a bit more information from you."

"Oh? Like what?" Cadence asked.

"Well I think the root of his disappearing problem might be tied in with your marital problem."

"What marital problem?"

"Well, how often are you two... intimate?"

"Oh all the time. We hug and kiss whenever we see each other and we cuddle and snuggle all night in bed."

"Okay that's good. But I mean, how often do the two of you get busy... like, sexually." She asked.

"Oh, ugh." Cadence grimaced as if Twilight had farted the word at her. "Is that what this is about?"

"Yeah, I think so."

"Well come on Twilight, you know how stallions are." Twilight arched an eyebrow at her. "Don't you have a coltfriend?"

"No."

"Oh, I'm sorry, I didn't mean to assume. Are you of the... alternative persuasion?"

"No I'm just- unattached."

"Ugh, I can't say I don't envy you. It's just all the time with them wanting it. It's like it's all they can think about."

"And you don't!?" Twilight asked.

"Please Twilight. You're starting to sound like one of them. Those sort of base desires. They're... well they're beneath me quite frankly."

"Well I'm sorry Cadence. But not everypony is as enlightened as you are. Your husband for one!"

"Well that's just too bad then." She said. Twilight was truly taken aback at that.

"You can't just punish somepony for something they have no control over! For being who they are!"

"Well then how are they ever going to change?" She said. Twilight didn't even know how to respond to that. She was going to ask how Cadence ever planned on having foals. But now she prayed that she never did. If this was how she was going to treat her husband... There was a knock at the door.

"Cadie, it's me!" Shining opened the door, wearing an apron. "Come on, it's Wednesday cooking fun time."

"Oh my goodness! I almost forgot!" Cadence said smiling, jumping to her hooves.

Twilight sat on the stool at the breakfast bar watching them cook. It was surreal. They looked genuinely happy together. Shining mixed some batter and dabbed some on her nose, licking it playfully. She giggled and teased him back. There were plenty of kisses too. Twilight had never felt more conflicted. She spent the rest of the afternoon just casually observing them. They seemed so good together. She didn't know who to side with. There was no right or wrong side. It was a fog of moral ambiguity.

On the one hoof, Shining was a stallion with needs. Real physical needs. But on the other hoof, the way he was going about dealing with them was dishonest, and downright reckless. There had to be something she could do.

The following week, Twilight was on high alert. She knew it was a danger night for him. When the report came to Cadence that he'd vanished again, Twilight took off out the window after him. She knew where he'd be headed to sate his need anonymously. She pitied the physically deprived stallion. But at the same time, she didn't want him just getting with any old mare of the night. Tonight she put her three-part plan into action to turn him from this dark path. Even leaving after him, by air, she arrived long before he did. Just as before, she staked out the rooftop waiting for him to enter the building. This time she entered immediately after.

"Ah, Missy." The maître d' waved her through as she walked by. "Full house tonight. Head down to room six." Twilight kept her head low and did as she was told. As before she walked into the dim room and checked the hole. The room on the other side was empty just as before. She hesitated to push the light switch, knowing full well what it would mean. But she loved him. And in her heart of hearts she knew that there was nothing she wouldn't do for him.

She flipped the switch, turning on the red light. The door to the other room opened and closed quickly. She recognized the white fetlocks on the cloaked stallion that had stepped in. She backed away, ready for what would come next. Even though she expected it, nothing could really have prepared her for it. But there it was, her brothers erect penis standing before her.

She'd seen it from time to time growing up. It was a fact of life when ponies generally didn't wear clothes. She never really made a point to gawk at it. But the blue mottling on his pale white skin had a distinctive pattern to it that she recognized.

It was bigger than she remembered. It bobbed in time with his heartbeat, aching for the tender touch of a mare. She could hear his hind legs stepping anxiously on the far side of the wall.

"Please?" Came a whimper from the other side. "Please? I really need this." It was muffled and off-pitched from his discomfort. But a lifetime of growing up beside him let her still recognize Shining's voice.

She reached out with a hoof, gently touching his shaft. It jumped at the contact. She could hear him moan on the other side. She took his shaft with both hooves. She understood the basic mechanics of the act. She'd done it before a number of times with a plastic simulacra that she was not too proud about purchasing. She caressed his shaft slowly, being careful not to be too rough with it. Already, precum was dribbling from his head. She worked her hoof across his sensitive tip, smearing the lubricant all along his length. She leaned forward, taking a deep whiff of his aroma.

She was overwhelmed with a powerful rush of pheromones, triggering her deepest, animistic desires. With his scent came a strong sense of nostalgia, filling her mind with the memories of an adolescent colt, with whom she once shared a bedroom. Maybe Cadence was onto something about transcending this kind of base desire, Twilight thought as she slowly felt her self control fading away. But she didn't think she needed to abstain from this to reach some kind of metaphorical nirvana.

She was already there.

She leaned in closer, running her tongue over his tip, and down his length, and back again. Her saliva, mixed with his precum kept her hooves moving smoothly as she continued to massage him. By the time she slid him into her mouth, is wasn't out of pity, but desire.

She could just barely make out his muffled cry as she took more of him into her warm mouth. She nearly gagged when he suddenly lurched forward, revealing his full length through the hole. She recovered quickly, keeping his position under control as she continued to suck him and work his shaft with her hooves. She got herself into a pretty good rhythm.

"Ngh, ooh that's sooo good!" She heard him moan. Part of her felt proud that she could please him so well. There was only so much one could know about technique without practice. And she never really had the opportunity before. Well, except for last week, but she didn't seize it.

She thought about that for a moment. Would it really have been any different? Sucking one dick through a hole in the wall versus another? Logically, it shouldn't have made a difference. But even so, last week she was repulsed by the idea. And now... she could feel her seat getting wet from her excitement. She'd actually been looking forward to this. She wanted to suck a dick tonight. But not just any dick. This dick!

"How dare she?" Twilight thought. "How dare Cadence turn down this wonderful dick? This beautiful phallus?" Twilight took in more and more, continuously swallowing as she tried to take him into her throat. "The smell! The taste!" She was in ecstasy. Her anger at Cadence fueled her gusto. "To hay with her! She doesn't deserve this dick!" Twilight redoubled her efforts. She was intent on giving her brother the best blowjob he'd ever had in his life. She'd suck his dick right off!

Shining's leg couldn't stop twitching. He felt his dick being inhaled by a cock-starved mare sucking dick like she invented it. Twilight timed her breathing as she choked herself with her brother's cock. Her throat burned as she let him ravage her esophagus. She didn't stop swallowing until she felt her horn hit the wall.

Shining felt his abdominal muscles clenching. Twilight pulled back a final time taking a last quick breath before practically swallowing him whole. The last bulb in his mind blew out. Any utterances from the stallion were little more than a string of incoherent vowels. His balls tightened. Twilight felt his cock flare in her throat, crushing against her airway. His entire cock swelled, filling her mouth and stretching her jaw. Tears ran down her cheeks. She felt him pump load after load down her throat, filling her stomach with his hot seed. She struggled to pull him from her throat, but she has held hostage by his flared head holding him in place. Her lungs were on fire, in dire need of oxygen. Her vision started to fade into a dark tunnel.

The thirty seconds of him down her throat felt like an eternity. But before she passed out, he was able to withdraw. Twilight gasped and sputtered, sharply inhaling again, to catch her breath. Almost like a balloon losing air, she watched him wither and vanish back out through the hole before she had one more chance to touch it or kiss it goodbye. She tried to look through the hole again but was surprised by something else. She almost got a paper cut on her cheek as he fed the one hundred bit-note through.

"That- that was- most amazing- I've ever- here." He said. Twilight didn't realize this was a paid position. But she was never want for money as a princess.

"I do it for fun." She said. She'd tried to disguise her voice. But she found it was already quite ragged after what she'd just survived.

"Oh, are you sure? Okay." He pulled the money away. She wanted to say something. But by the time she did, he'd already exited his booth. Twilight collapsed off of her chair, savoring the flavor of his cum, still freshly smeared on her lips. She turned off the red light and teleported away. Back on the roof, she quickly cleaned herself of the mess she'd made and discarded her robe. She could always get another. But she refused to show up back at the castle covered in her brother's semen.

Twilight was greeted with the sight of her brother walking out of the building. But this time, unlike last week, he was barely able to walk. Strange as it was, she felt a tremendous sense of pride. And now, jealousy. Jealous that after all that work, he'd be going off to some other mare's bed.

Twilight didn't sleep that night. Her mind kept replaying what had happened. Everything that led up to it. And how she felt after. Every time, it always circled back to jealousy. It was like the night before his wedding all over again. But this time she knew why. She didn't know how she'd be able to wait an entire week before being able to have him again. But luckily for her, she wouldn't have to.

"Twilight!" Cadence shouted. It was the early evening of the next day. Twilight had finally dozed off just before dawn that morning and ended up sleeping through the whole day.

"Wh- what is it?" Twilight asked, her voice still somewhat raspy.

"Shining's gone! They just reported him missing a few minutes ago!" She said. This was something that she did not anticipate. A double event. Something had changed. Suddenly the last twenty four hours came rushing back. She knew very well what had changed.

"This is it! Today's the day I can end this!" Twilight said. She pulled the dark sheet from the bed, rolling it into a ball in her bag. She did some quick stretches and shook herself awake. "Geronimo!" She jumped from her window off into the night. She dropped down to ground level near the infamous house of ill-repute, pulling the sheet out and clasping it over her shoulders into a new cloak and walked in.

"Ah, Missy, there's a client requesting you down in room four." He said as she passed his desk. She quietly stepped into the booth and peered through the hole. Sure enough a familiar form was waiting on the other side. He looked like he'd be pacing if there was room enough. Twilight was practically giddy. She pushed the red switch. She heard him practically rush over.

"Um, I- I know we're not supposed to talk but, are you the mare that was here last night? I mean I know you're probably here every night. Um, I don't mean that but um, I tried to give you a big tip last night but you said that you do it for fun? Is that you?"

"Mmhmm." Twilight confirmed.

"Oh, oh my gosh, uh I was hoping we could, um if you could uh, again?" Twilight practically giggled. She'd never seen her big, confident brother so flustered before. She must have left quite an impression on him. She leaned back and opened her mouth.

"Aaaaaaaa." She said as though she were opening her mouth at the doctor's office. Shining practically tripped over himself trying to get his swollen member through the hole. Twilight didn't waste any time getting to work on him tonight. She licked and sucked all over the surface of his member, getting him good and slick. Once again Twilight's own wetness made its presence very known. She decided that she wouldn't wait another moment to put off her own desires.

Shining whimpered as his cock slipped free of her warm mouth. The air on his exposed stallionhood felt extra cold. Twilight turned around hiked up her cape. She lifted her tail away and backed up against his steely rod. Shining's knees nearly gave out as he felt himself become enveloped by her hot marehood. She pushed herself all the way back until her ass was pressed squarely against the hole in the wall. Holding herself there, she waited for him to react.

Shining's eyes rolled uncontrollably in his head. It was the first time he'd felt the touch of a mare's love tunnel in almost a year. He did not expect this rare treat tonight. His hips began to move all on their own. Twilight did her best to brace herself, holding onto the wooden stool in front of her as he started to buck uncontrollably. He was like a wild rabbit, jack-hammering away in rapid succession.

He was practically foaming at the mouth with raw, unadulterated lust. There was no pretense of rhythm or pacing for mutual pleasure. He wasn't making love to this mare. He was fucking her through the hole. It was the perfect word for the act. He fucked her hard. He fucked her fast. He fucked her for all the nights of pleasure that he'd missed out on. He fucked her for every 'no' that he'd accepted. Each thrust vented his emotions. He poured into them his frustration, desperation, and regret. He used the mare for his pleasure. HE was in control now. HE decided that he was going to have sex now. Twilight's hoof moved in a furious blur on her swollen mound as he railed her with all his might.

WUMP WUMP WUMP

Each time he slammed into the wall it caused her to bounce off of it and slap back against it. Her pussy gripped and rippled again as she came a second time, soaking his cock with her wetness. He'd fucked right through her first orgasm without even missing a beat. She didn't mind working to get herself off. She was here for him. He needed this. And she wanted to be the one to give it to him. She felt him begin to swell inside her, his head flaring wide. She got ready to pull away so she could swallow his delicious cum.

WUMP WUMP SMASH!

After years of being sucked, fucked, bucked and rutted, the thin drywall separating the stalls finally gave out as Shining careened through, landing on top of the mare he was fucking. He was so close, he didn't even pause, wrapping his hooves around her waist. He took a step forward to steady himself and slipped in her wet puddle of marecum. Falling backwards, he pulled her with him, landing square on his back with Twilight impaled on his staff.

With the width of the wall removed, Twilight arched backwards, sinking clear to the hilt, deeper than he'd ever gone before. She didn't have time to react as she felt his first, powerful jet of cum blast from him forcefully against her insides. She moaned as she felt him stretching her tummy as his cum exploded forth in a hot torrent against her innermost depths. Filled to the brim, he kept pumping more of his potent seed deep into her as it forced its way past his swollen tip, spraying out of her stretched marehood from around his shaft, mixed with her juices in rivulets of hot, white cream.

The muscles in Shining's face relaxed just long enough for him to be able to open his eyes and see the maître d' standing over him.

"What the buck did you do?" He shouted at him. Shining looked down at the mare still impaled on his rod, squinting in the dim light. She flipped her violet bangs out of her face and looked back at his eyes. They were the size of dinner plates. He shook his head and did a double-take. His sister was sitting on his lap with his cock buried in her.

"What the buck did I do!" Shining repeated. Twilight panicked. They needed to get out of there before the growing crowd recognized one of them. In a purple flash, the both vanished from the scene, leaving behind only a sticky stain of their shame.

The entwined pair reappeared on the roof of a building a few blocks away. Twilight's tired knees lifted her off of him as his cock finally slipped free with a wet plop, and then slapping against the sticky fur of his cum-smeared belly.

"Wha- wha- wha..." Shining babbled incoherently on the rooftop. He'd crossed some kind of impossible threshold. Up was down, black was white, reason was insanity. Twilight feared that she'd broken his mind. This was not at all how she'd planned on revealing her plan. Something this big required the careful timing of subtle clues to let his mind slowly accept the possibility. This was too sudden.

"Shining, I know you feel really confused right now and I know you have a lot of questions." Twilight tried to plead with him. He looked at her, but his eyes didn't really focus on her. It was more like he was looking through her at something a thousand yards away.

"It's... kay... Twi..." He whispered. She stepped over him, letting him lay down. She leaned down close, checking his vitals for shock. "Twi?"

"Yeah?" Twilight asked, happy for some responsiveness.

"Dripping." He said. Twilight looked underneath her. More of him was still leaking from her, getting on his leg under her.

"Oh, sorry." She moved aside. "Are you okay?"

"Oh. Yeah. Fine. How about you?"

"I'm okay." Twilight said.

"Are you sure? I was pretty... rough."

"It's okay. I liked it." She said.

"I liked it too." He said with a drunk smile.

"Let's get you home."

"Cadie's gonna be mad."

"Let's not tell Cadie about this okay?" She said.

"Okay."

Shining Armor walked out to the balcony. "Good morning sleepy head." Twilight greeted him from her brunch table.

"I was told to meet you out here again." He sat down beside her. "I had the weirdest dream last night." He said.

"Shining..."

"Sorry. I wasn't sure how we were going to deal with... what happened." He said.

"Well I'll start." Twilight said. "Cadence asked me to figure out where you'd been going off to at night. I followed you to... that place. And when I figured out what it was you were doing there, I wanted to figure out why. That was when I found out about you and Cadie's problem. The first time I was on the other side of that wall, it was out of pity and protectiveness." She paused. "But then it turned into something else." She blushed. "We had sex last night, Shining. What happens next depends on how you feel about that." She let the words hang there in the air, giving him something to think about. He lowered his head.

"How should I feel about it?"

"I don't care what you or I think you should feel, Shiny. I'm asking what you honestly feel in your heart. I enjoyed last night. And I think you did too. Didn't you?" He could barely look at her in his shame. "Hey, look at me. And be honest. Didn't you?"

"Yes."

"Shining, I know you love Cadence. And I know you want to be faithful to her, but you shouldn't have to live in a sexless marriage." She put her hoof on his. "But I don't want you going out like that and making everypony worry. You should only be doing that sort of thing with a pony who really cares about you. If you would let me, I could be the one to help with your... needs."

"But what about Cadence?"

"We'll talk to Cadence. I think I have a plan that will fix everything up just right."

"Shining Francis Armor! I can't believe you'd do this behind my back!" Cadence fumed. "And then you have the nerve to lie to me about it!"

"I'm so sorry Cadence! I never meant for it to get this bad! I just wish Twilight had intervened sooner!" Shining cried.

"It's okay Shining. I'm going to make sure that you're taken good care of from now on." Twilight said.

"Thank you so much for this Twilight! You have no idea how much this means to us both!" Cadence said.

"It's okay Cadence. I'm just glad I was able to help before it was too late." She turned to Shining. "From now on, when you feel tempted, you just let me know and I'll come help! Twilight said. Even if I have to stay up with you all night in the guest room or bring you back to Ponyville myself! I'll do what I must."

"Thank you again Twilight. You may have saved our marriage!" She hugged Shining. He winked at Twilight over her shoulder. "But really Shining, you're better than this. A gambling addiction?"
