What She Loves The Most
by Dashiel
The treehouse was empty. Twilight had made sure, twice. Spike was out on an errand which would take several days and everypony else thought she was heading to Canterlot. The doors were locked, the windows shuttered and the lights were out. It was time.
-oOo-
It had been one of those weeks; frustration after frustration, no task successful, everypony short with each other... Twilight could feel the tension trapped in every muscle. She had found herself grinding her teeth at breakfast, merely at the thought of another day with her friends. It was, it had to be said, time for a holiday.
The scroll, then, had come at just the right time. In a small ball of mage-light, she read it again.
Dearest Dusk,
I miss you, big brother, and I need to meet with you again. We have so much to talk about, I'm sure plenty has come up that you need to share.
Love, Glimmer.
Twilight trembled as she placed the scroll face down and hastily scribbled on the back a reply. Code words, all of it, and as thin as ever there were. She knew what her brother wanted to share, and she was only too happy to provide it.
Dear Glimmer Shield,
I miss you too. I have so many stories to share with you. Through thick and thin, we push forwards. I'll bring a change of clothes and meet you at the cabin.
Love, Dusk Shine.
Her brother wanted to see her, eh? Well, Twilight wanted to see her brother too, very much. With one minor adjustment, that her brother loved more than he dared say. She sent the scroll on its way with a flicker of magic from her horn, and then set about preparing for the real spell.
-oOo-
Long ago, she had discovered just how much she loved her brother. He had been the most important thing in her life for many years. Many long, long years... and as he had grown up, so had she. It had started innocently enough: she'd asked him why girls peed from their behinds whilst boys peed from below, and he'd shown her the difference between colts and fillies. She'd devoured all the books, thereafter, on sex and reproduction in an effort to understand. Finally, she'd decided she needed a live subject.
She drooled a little even now, thinking about it, her tail twitching involuntarily as her velvety-smooth cunt dripped with mare-juice in anticipation. Her brother had been asleep, standing up in his dormitory. Even then, he'd been practicing for the guards. She'd snuck below him to get a better look, scooching around. Her brother's cock had been hidden deep within his sheath, but that hadn't stopped her. Nuzzling carefully, she brought her nostrils close to that musky crevice. Taking a deep breath as she examined him, the scent of male pony had aroused her deeply. She hadn't known what it was, back then. She'd been growing, of course, and was close to adulthood. A few seasons shy of having her own foals, nonetheless her bodily desires had been making themselves known in more or less obvious ways.
The attraction she felt for a stallion, strong and proud, was one of them. Her tongue, sweet and innocent, flicked out as she tasted her brother. It was bitter, powerful, and she wanted more. She couldn't help herself, she licked and fondled her brother's bulging sheath and balls with her tongue and lips until - wonder of wonders - his cock started to drop like when he wanted to pee. It grew, longer and longer, as the astonished filly looked on. Hesitant, but not willing to abandon her prize just yet, young filly Twilight had kept at it. Drawn to that stiff rod like a moth to a flame, she found herself taking the head in her muzzle, bobbing back and forth.
Soft whinnies had brought her back from whatever heights of passion she had been scaling. "That's... that's wonderful, Twily... but..."
She'd frozen, stock still, with the stiff and growing cock of her brother stuffed halfway up her muzzle, unsure of what to do.
"Shhh," her brother had said softly, "it's okay Twi, just turn around, I'll make you feel real good too, okay?"
Twilight had panicked, but had done as her bigger brother asked. After all, he was her brother. He'd never do anything bad, would he? And it turned out, he wouldn't. He'd carefully stepped over her, and then dove his great blunt muzzle into her behind. A hot, long tongue had wound itself sensuously deep into parts of her body she didn't know she'd had. Wracked with burning waves of ecstasy as they flooded her young body, she'd experienced her first orgasm at the lips and tongue of her brother. He'd smacked his lips noisily, dripping with her mare-cream, and then whispered in her ears, "you liked that, didn't you, Twily?"
"Uh huh..."
"So does Cadence. You wanna know what else Cadence likes?"
"Uh huh!" Young Twilight had shivered, still up on some cloud so high, she doubted even the most talented pegasus could reach it.
Her brother had jumped upon her back, his teeth fastening to her mane. "Hold still now, sis, this might hurt a little the first time... but you're nice and wet, even if you're a tight little filly, so we'll go slow, okay?"
"...Okay," she had whispered, as she felt something else poking under her tail. It felt a little like a hoof, though it was thinner, and at once both softer and harder. Her brother kicked a little, holding her tightly with his forehooves as he walked himself forwards. She gasped, working out what it was in an instant. Her brother's cock, his gorgeous, tasty, huge cock, was sliding deep into her filly cunny. For a brief moment it met resistance, a bare few inches past her taut lips, but then he pushed harder and took her virginity. She cried out in pain, but he gripped her even harder with his teeth in her mane and kept on pushing. Slowly, the pain turned to pleasure. She was sore, it hurt, but... it also felt right, and good. He was as attentive at rutting as he had been at cunnilingus. He moved gently, but firmly and with great purpose. That huge stiff pony-cock of his slid, eventually, all the way in, and his heavy velveteen balls slapped at her backside. Unbidden, another orgasm had wracked her body and she came in a forceful gush that propelled his own hot seed out to spatter on the stone floor of his bedroom. Spent, he'd dismounted, and she'd trotted off to bathe his scent off her flanks and wash the remainder of his seed from her inner-most sanctum, taking a long time and enjoying the glow of having a real stallion's musk upon her.
If the princess had seen a change in the filly who was rapidly becoming a mare, she'd never said anything, even though Twilight had taken an interest in some rather esoteric and rare spells. It had all been with a purpose though; an experiment which she would conduct with her brother. She had felt an incredible orgasm as a filly, but how did it feel for a stallion? When she'd first presented herself as her male alter-ego - which she'd named Dusk Shine - Shining Armor hadn't known what to say... but then curiosity had gotten the better of him. He'd heard that mares could have multiple orgasms, whereas stallions could generally only have one at a time. He'd learned the same spell, although it had taken him much longer than for his sister, and eventually had stood before his little brother Dusk as sister Glimmer Shield.
They'd tried it as stallions, they'd tried it as mares, and then they tried it switched... and just to make sure the results were definite, they'd tried it all again. And again. And again. Eventually, they'd given up all pretense of a simple experiment and just learned how to please each other, in whichever sex they desired.
And now, with all the tension Twilight had been through the previous week, the fact that her brother wanted to be her sister meant that she'd be able to work off some of that frustration by boning her bigger brother in his female alter-ego. She had to admit, there was a certain refreshing glow from being a stallion, thrusting into a willing and waiting subservient mare that quite washed away all the trials that life could throw at her.
The shack was small, but comfortable... and most of all, private. Nopony knew of it except her and her brother. Now, it would play host to Dusk Shine and Glimmer Shield.
The teleport was simple for Dusk. Growing up, they'd had to spend a couple of days getting to the remote cabin that they'd appropriated, cutting any time together rather short. Now, he could just pop and appear there, and spend so much more time in the hooves of his secret lover.
Dusk approached the cabin, nostrils flaring. Twilight, as Dusk, liked to get in touch with her baser nature. Bookish and prim was for Twilight. Studly and impulsive was for Dusk. He sniffed and snorted all along the path to the cabin; he could smell mare in heat, though... there was something else. After all this time, Dusk knew the scent of his willing mate, but now it was tinged with the scent of another. He recognized the smell, but just couldn't place it. It had to be something about male nostrils, they made everything taste different.
Knocking on the door, Dusk made himself known. "Are you there, sister?" Dusk called. He was sweaty and grimy from the trek through the forest that surrounded the hut, his fur matted with tree sap and his body exuding the powerful musk of a stallion. Teleportation straight to the destination was possible, but why spoil the fun of the anticipation? Dusk preferred the workout, to build his masterful scent up to spread all over his willing mare. What he heard next startled him.
"T-twilight? Is that... is that really you?"
Dusk stopped short as he nosed the door open. It was a nubile mare he could smell, and the voice was familiar... the only problem was, it wasn't Glimmer. It was Cadence.
"Cadence? Princess? What are you..?" Dusk began, before clearing his throat and asking in a demanding voice, "I mean, uh, who are you and what are you doing in my--"
"Oh, Twilight, it's alright!" laughed the pink alicorn princess. "My Shiny has explained everything to me, and... well, I just thought that... now we're family, we could..."
Dusk's heart skipped a beat. "We could... keep it in the family?" He swallowed, the lump in his throat refusing to go down, the lump between his hind legs also refusing to go down.
Cadence clapped her hooves together, "Oh! You do think it's a good idea! Oh I'm so pleased! And... oh my, you're so... so... manly! I can see why Glimmer here speaks so... highly of you." Cadence licked her lips, eyes roving all over Twilight's masculine body.
"Yes, well, I..." Dusk harrumphed, his cock swinging freely between his legs as the scent of an aroused mare in estrus assaulted his senses. It made it quite hard to think, even without the added pressures that had led him here in the first place. He felt quite weak at the knees, seeing Cadence again. Of course, seeing her like this was altogether new. He wanted her. She was lithe and trim, every curve succulent and juicy, her mane sparkled, begging to be mussed and bitten by a commanding male as she was laid out beneath him.
"Shin-- I mean, of course, Glimmer, darling... are you coming? I'm not sure I can hold your brother back much longer..." Cadence blushed, putting a wing over her muzzle. "I'm not sure I want to! You know... Shiny and I have been trying for a foal, but... he hasn't managed it yet. Do you think... no... I mean..."
Dusk gulped. His alter-ego's babysitter was before him, spread out on a large, frilly bed, drowning in silken pillows, hind legs artfully spread to reveal the briefest hint of her pink netherlips... and she was in heat. She was very much in heat. Glimmer would always spell herself to prevent accidents. This time... Dusk gulped again... his lover wanted... she could become... the intensity of the thought was almost a physical ache. Did he dare? Could he take that wanton creature, have her for his very own, bury himself in her folds and plant the seeds of their physical excess within the deepest chambers of her body?
Dusk found himself drooling. Of course he could. If his brother couldn't... but that was silly. It was obviously just a trick. She wouldn't let that happen. But if she weren't kidding... Dusk licked his lips. Eagerly, he clambered onto the bed. He sank into it; Cadence had done some remodelling, previously the bed had been little more than a rutting-post. This was... sensuous. Then again, Cadence was the alicorn of love. No wonder she knew a thing or two about how to do it right, let alone was open to the idea of herding.
Dusk fell forwards, nose inches from an exquisite hind leg. He stuck out his tongue, lapping at her fetlocks. Nimbly, he bit them. Crawling forwards, he nibbled all the way up her calf until his muzzle was under her tail. Laughing, she slapped him with her silken strands and rolled out the way. He caught at her wing, growling playfully. She arched her back, fluttering weakly like some caught bird. He crawled closer, dragging her delightfully clean and feminine body closer to his hulking, masculine bulk. Biting all over her body, little soft nips that reminded the mare who was the stallion, his powerful forelegs pulled her under him.
It was awkward, there on the bed. They were on their sides, entwined in a fighting mass of teeth and hooves; kissing, licking and and biting in equal measure as Dusk sought to own his princess. Slowly, he forced his way in, under her tail which the princess kept resolutely, playfully down against her haunches. She liked it rough, whinnying with pleasure when Dusk bit into an ear, pulling her head back forcefully. Finally, achingly, the alicorn lifted her tail and Dusk plunged his malehood into those tight, wet, hot folds. They both gasped sensuously, writhing together as Dusk's heavy, stiff cock penetrated her dripping slit.
Dusk heaved himself back and forth, neighing with pleasure, teeth gripping lavender mane as he mated with the mare. He grunted, crying out in short whinnying sobs as the need to release grew.
Suddenly, Cadence withdrew. She snaked herself out from under him, and his cock plunged up between her cheeks, painting her tail and backside in precum. "Steady, my love, your mare needs to be... mounted properly, for a mating such as this..."
Feeling almost a physical pain from being denied release, Dusk snapped his teeth. Cadence just laughed and rolled off the bed, flicking her tail high and free. Dusk drew back his top lip, inhaling the scent of mare. Oh, goddess, but she was in heat. Cadence, one-time baby-sitter to her alter-ego, was in heat... and she was needy as any filly.
Bounding to his hooves, Dusk plunged his blunt muzzle under her tail, tongue lapping at the sweet juices which flowed from his lover. Unable to stop himself, tasting the raw, untempered readiness, Dusk mounted, his heavy weight falling upon Cadence's strong back. She was... different to Glimmer. She was bigger, different proportioned, and of course those wings! Dusk hugged his mate with his powerful forelegs, rubbing himself against her. He was slick with sweat by now, salty drops spilling from his flanks much as they were spurting from his buried malehood. She was wet, her love-tunnel slick and welcoming, her muscles clamping down and massaging his mighty rod as he forced it deeper and deeper into her. Every thrust was heaven, a symphony of pleasure as his lover squeezed his cock in a rhythm as old as time itself. Cadence didn't moan like Glimmer - her brother was needy and loud as a mare - she merely grunted in animal passion. She was a feral beast, demanding service, demanding his seed, presenting her bounty and expecting her wishes and her tight, needy cunt to be fulfilled. Dusk was only too glad to assist.
Dusk felt that growing tenseness, that raging torrent building within him. It filled him, bursting from every orifice as the orgasm grew and grew. He tensed up, whinnying with every breath as he rutted, pure animal need now flowing through him. His teeth clamped hard upon her mane, his legs kicked spasmodically and he drew the barrel of his helpless lover tight against his body as his burning tide of love exploded into Cadence's innermost cavern.
Spent, Dusk fell against his lover, breathing heavily. He was strangely exhausted, drained. "Oh, Cadence, my love," Dusk moaned, "I am so glad my sister shared you with me..."
"Oh so am I, Twilight Sparkle," Cadence replied, her eyes flashing green. "I do so love family reunions... and... family unions."
"What? What did you... wait..." Dusk found himself slipping. His cock was still buried deep within Cadence, but something odd was happening to his lover. Her voluptuous curves were sharpening, becoming... somehow more angular. As the purple coat shimmered and became black, he realized who this was. This wasn't Cadence at all.
"Chrysalis! What, but... how? Where's..?"
Queen Chrysalis, finally assuming her true form, laughed heartily. She twisted her head around sinuously to stare at Dusk Shine with her luminous eyes. "Oh, Twilight, your sister is safe. He's... sleeping it off. Or should I say she."
"Let him go! Let... let me go!" Dusk roared, kicking his legs futiley, but it was no good. The changeling queen held him most tightly.
"Oh, yes, my reluctant lover. Shining Armor won't be around for a long time, as Glimmer Shield is going to be very busy... much are you, after a few... modification."
"Modifica-? What are you... No! No! Let me go!"
"Oh yes, lover, I have you seed, now all I need is your equipment!" Chrysalis hissed in pleasure and lunged backwards. To his horror, Dusk felt jaws fasten around all parts of his wedding tackle, and then the burning, shooting terror of teeth clamping shut.
Dusk screamed. He fell to the floor, released from the nether-jaws of the queen, and curled into a ball. Between his legs was nothing but fire and blood; Chrysalis had bitten everything off.
Dusk could barely speak as he writhed in pain. "W-w-why? How? Oh Celestia, help me!"
Chrysalis laughed, kicking the injured half-stallion in the head before presenting her backside. "We changelings have an interesting life-cycle, Twilight Sparkle. We need the seed others to reproduce, and the freshest seed is always taken straight from the fruit."
Dusk looked up, through the tears, in abject horror as a beak and a pair of jaws snapped hungrily at a bloodied lump that was rapidly vanishing into the cavernous crevices beneath Chrysalis' tail. In moments, the remains of her cock and balls had been devoured by the unholy vagina dentata of the changeling queen, accompanied by Dusk's panicked, sob-filled tears and the queen's cruel laughter.
"Please... kill me quickly then... please... it hurts! Oh Celestia it hurts!"
Chrysalis almost looked shocked. "Kill you? Oh, my dear Twilight, whyever would I want to do that?"
"You-you're going t-to let me b-bleed out?"
"Oh no, my dear, you're going to live, and you're going to prosper... now hold still, I'm told this stings a little..."
Dusk furrowed his brow momentarily, before the hot, salty liquid started splashing on his flanks. He twisted and turned to escape the stream, but it was no good. It only led him to discover the whereabouts of Glimmer Shield. She was beneath the bed, immobile, encased in some sort of green sack. The same sort of sack, Dusk realised, as was growing around her, made from whatever Chrysalis was depositing on her. Dusk had to escape, he had to! He had to escape, tell everyone, do something, anything... but it all hurt to much! Before he could gather his wits about himself, the world faded into a dark green.
-oOo-
Dusk came to slowly, and he quickly glanced around at his surroundings through what appeared to be some sort of ropey film. He was in a darkened cavern of some sort, the walls were made out of what appeared to be blackened chitin, lit by some sort of chemical lights. His pain was gone. In fact, he realized, a lot of everything was gone. He was female again, but not from reversal of his own spell. It had to be the goop... goop which he was still fully encased in. The world outside was strange and green, and all the sounds were odd and distorted.
He could still recognize, however, the form of Chrysalis as she sidled up to the pod, and still hear the creature talk.
"Ah, Twilight, welcome back... I've been waiting for this. May I present your brother, Glimmer Shield?" Chrysalis beckoned, and a shambling creature plodded listlessly up to the queen. "She's grown quite used to her new duties, haven't you my dear?" Chrysalis asked, as she trotted around the docile mare.
The docile, heavily pregnant mare.
"She, and you, are going to be mothers to my newest brood," Chrysalis said, raising her tail and showing off her magnificently large penis and balls. They swung heavily, loaded with seed. The queen easily mounted what used to be Glimmer Shield, though the docile brood-mare beast showed none of the intelligence she had once posessed. The creature was beyond rotund, her belly scraping the floor as glowing blue spots of light oozed and moved around in her distended belly.
"I think I'll impregnate you with the larval stage, Twilight, it's so much more fascinating than growing the eggs... and you'll get to investigate every part of your eventual total consummation. I do know that investigating things is what you love the most."
Dusk screamed as fat tendrils wormed their way into her pod, wrapping themselves around her legs and easing themselves into her swollen pussy-lips. She cried, wordlessly, as she felt the first of thousands of larvae settle within her body, growing fat as she was forced to nourish them until-

It's an XMAS miracle!
