Everywhere the Light Touches

Atop her throne, sat Princess Celestia, glorious goddess of the sun and maternal mare. Like many alicorns, her body was large, powered by the energies of the sun. An amazonian frame, holding up an absolute pair of pillowesque buttocks, a horsecock easily described as titanic and hard enough to shatter mountains, and finally a pair of breasts so off the scale they had to invent a bra size just for her, the double CE's. Twice the size of her own head each, she bore them with pride. Or usually, she did.

This day, her fingers dug into the arms of her throne. A deep, throbbing need ran up and down her body, from crotch to blushing cheeks. She tried to take deep breathes, her body overheated and trembling. HER body! Overheated! She'd already cancelled court for the day, a noble mare's bust enough to make her want to bust. The only ponies left were her guard, and she was having thoughts about all kinds of holes.

Her musing was interrupted by the doors flinging open, her sister striding in. Like Celestia, Luna was heavily endowed, if not to the size of her *big* sister, and unlike the matronly Celestia, Luna was rippling with muscle from years of fighting nightmares.

"Sister! You cancelled day court?! Our nephew was most concerned about you. And losing his spot, I assume," she added in a grumble.

Celestia had to gulp down her saliva, her cock tenting her dress. Luna's breasts stretched her negligee to its absolute limit, the lift of her bust raising the fabric by a few inches, her buttocks hanging out and the very tip of her soft, supple pussy visible to her sister. Luna tilted her head as she watched Celestia struggle, before her eyes alighted on the...hard issue.

"Sister, really, in court?! Well, I can hardly blame you, the fashion of the nobles these days...or did Twilight come visit? She's coming along nicely as an alicorn, isn't she? It seems every week she's here to show you her 'new outfit' from Rarity." Luna teased. "A little bit tighter and more revealing each time!"

She laughed, "Shall I leave you to it-" Celestia could no longer hold back, pouncing on Luna, each wobble of her tits having worn down Celestia's will a little more. She straddled Luna's chest, thrusting her fat cock between Luna's soft bosoms.

Luna scowled in annoyance, "Sister! You are meant to ask first, in private! Why I-...I...? You...you are in heat," she mumbled, sniffing at the tip of the cock between her tits. She put her tongue out, allowing it to touch her tongue, closing her eyes in ecstasy at the very taste. "Delicious...forget our childish protests, dear sister! This is wonderful news-fill us up! Give more alicorns unto the world," she encouraged, now holding her breasts to help massage the hot flesh.

"Oh I will Sister...oh I smell that hot little pussy juicing up for me, I'll fuck you so good no other cock will touch the sides," she groaned, dripping precum over her sister's dark tits, rivulets running down the curved flesh. She moved between Luna's legs, tearing her negligee off of her body. She spread Luna's legs wide, admiring her dark labia and glistening, winking hole. She rested her hot cock on the soft flesh, sighing happily as she rubbed up against it. Their mingled juices made a puddle underneath Luna's prodigious bottom, Celestia pulling back to press her cock tip right against that wanting hole. Luna blinked. Despite their incestuous tendencies, they'd never actually done penetration.

"Sis...sister? That...it won't fit," she stammered.

Celestia grinned, close to demented, drool sliding down her chin. "Oh, don't fret little sister...I'll make it fit," she panted.

Luna blinked in panic before she felt Celestia begin to press forward. She gasped, feeling it slowly try to push in, spreading her lips wide, and her legs. She wriggled under her sister, Celestia's heavy tits resting on her own and pinning her in place.

"Mmmh...that's it, sister, play at struggling, we both know you love this," Celestia purred.

That, Luna couldn't refute. Something about her big, elder, powerful sister pinning her to the ground to breed her... she squealed, the lubrication the thought gave her enough to allow Celestia's cocktip to slip in and begin the stretch. Luna's legs trembled at the pleasured pain running through her pussy, as her sister pushed in further. At the size she was, she hit the cervix fairly fast, just short of the medial ring.

"Mmmh, oh sister, do you feel that? My tip kissing your cervix? Kissing you so deep and intimate?" she grinned evilly. "Ready for a french kiss? Maybe I should warm you up first," she purred.

She moved back slightly before pushing back in slowly, relishing every hard earned inch. Luna moaned, unable to move her hips, her sister's giant buttocks helping keep Luna pinned to the floor. Each thrust made Luna juice up further, helped by Celestia's own precum. Each thrust was easier than the last, and soon Celestia was pressing up against the cervix more and more.

"I'm gonna...gonna bust through that gate to your womb! I'm gonna fuck you right in your foal factory!" she cried, grabbing Luna's hips and fucking right up against the cervix, delivering punishing blows to force it to open up. She pulled out fully, before slamming in so hard and fast she broke down the cervix in one thrust and made her sister cum. Luna screamed in pleasure and pain as an orgasm ripped through her like her sister had.

Celestia hooked her arms under Luna's muscular thighs, lifting them and pinning them on top of Luna's tits and under Celestia's own suns. This position allowed her to piledrive her sister's pussy right to the womb, stretching her from lips to back. As she fucked her sister's cunt like a sex starved pervert, the doors swung open yet again to admit Prince Blueblood this time.

"Auntie! I-I...oh goodness," he mumbled, yanking his button up shirt away from his neck. Celestia glanced up at him, still busy pounding.

"Ah, nephew! Good. Come here. Help me pleasure your other aunt," she ordered.

He approached, unsure, but unwilling to refuse her. "What...do you..."

"Come put your tongue to work. I've seen your cock, even a normal mare wouldn't feel that,"

"Au-auntie!" he spluttered, shocked and mortified- more that she certainly wasn't wrong. Even with most of it buried deep in Luna, he could see her bulging cock veins- they alone put his nub of a cock to shame.

"Did I stutter? Come lick Luna's moonpie," she demanded, and he nodded, getting into position behind them both. He knelt, Celestia's massive, swollen ball sack swinging above him, her cunt just behind that dripping delicious smelling, fertile juices on his head. He sighed, but leaned forward, pressing his tongue to Luna's asshole. The mixed juices made it taste delicious, he had to admit, diving his tongue in further to lick deeper.

"Go ahead and stroke that tiny cock, nephew. Give praise to the rising of my sunray," she chuckled, as he ashamedly reaching down to undo his pants, palming his mushroom cock. He was ashamed of the size, and somehow, also got off on being put down for it. He wanted his aunt to demean him-the sexy alicorn paying attention to him lustfully at all would have been arousing even without his fetish.

Each thrust of Celestia's cock drenched him in fluid, precum and Luna's arousal matting his mane and facial fur. His tongue helped Luna reach orgasm once more, coating him from head to chest this time. He kept tonguing, afraid of his auntie's reaction if he stopped. After all, he'd never had anything up the royal rectum, and a massive godly futa cock was not a starting point for anal. Not, he felt, that it would ever actually stop his auntie.

"Nephew, move that tongue to my asshole- I'm ready to blast a load into my sister, and I want you to debase yourself to help me get there," she demanded.

He flushed, nodding, pulling his tongue from Luna and moving back to stand up, having to spread Celestia's cheeks to find her hole. He had to hold her cheeks apart as he tongued her to prevent her mighty suns from crushing his head. He had to move his head with her movements to both keep pleasing her and not run the risk of, again, being crushed.

His tongue moved in and out of her, tongue fucking her in a surprisingly acceptable manner. His tiny cock twitched and he shivered, a paltry spurt of cum now mixing with the mess on the floor.

Celestia grunted, snorting as she got closer and closer. "Here it cums, sister! Here comes the full force of the sun!" she cried.

With a massive contraction of her balls, which Blueblood felt against his chest, she shot hot cum right into her little sister's womb, and another shot, and another, and another...she had to sit up, her sister bloating with cum, stomach becoming round and full as it grew. The cum flooded Luna's system, filling her womb and shooting right up into her ovaries, the fertile cum and deep breeding ensuring an incestuous union. The last shot back washed out of Luna's now loose cunt, around her sister's massive cock. Celestia pulled out, letting the torrent flood the floor, her tail smacking away Blueblood as she massaged her length, spurting more cum shots onto Luna's limp, after-glowing body. She moved up her sister's body with the shots, the first drenching Luna's thighs and pussy all over again, the next painting her swollen, impregnated belly white, the next two were splashed on her heaving tits each, and the last drenched Luna's head, nothing but the very, very tips of her mane and tail escaping the penile hosing.

Blueblood, trying not to slip and fall face first into the cum sea, noticed with great shame that even Celestia's cockhead head across flared longer than his entire dick. He looked over at Luna, and couldn't see even her prodigious chest over her cum bloated belly, inspiring another jolt of thrilling jealousy as he glanced at where his tiny drop had landed.

She got up, staggering to go sit in her throne, her cock just barely limp and soaked in fluids. She left Luna soaking in her sister's cum, the alicorn more than content to bathe in the warm virility. "Blueblood! Come lick me clean. I have some letters to write," she smirked, her sister's early teasing about her former student having put ideas in her head.

Blueblood managed to crawl to her, his tongue lapping up the cum and juice from the breeding. "What...what did you have in mind, auntie?" He asked, suckling on the tip of her engorging member.

Her eyes glinted. "A very special party..."
