Celestia and Luna, two hyper-endowed alicorns, "collaborate" to impregnate Twilight Velvet with Equestria's next princess.

In a world where Luna never became Nightmare Moon, she and her sister Celestia share the Equestrian throne. And lately, they've been making plans for their successor: with the power of a magical ritual, they can impregnate a suitable mare with the child who will grow into the kingdom's next princess.

Twilight Velvet has spent the last two weeks living with Celestia and Luna, drooling over their six-foot-long cocks, and tonight is finally the night.

Chapter 1

“Ah, I could get used to this,” said Twilight Velvet, dabbing up the last crumbs of her chocolate torte with the tines of her dessert fork. “Castle living is everything I could have dreamed of.”

“We strive to be good hosts,” said Princess Luna. “Although our capable staff is responsible for most of the hospitality. And of course, your needs will be their highest priority in the coming months.”

“So… is tonight the night?” asked Velvet, looking across the table at the royal sisters. The dining room they shared was surprisingly intimate; they sat at a circular table not much bigger than the one in Twilight Velvet’s home.

“It can be,” said Princess Celestia. “Twilight Velvet, I should emphasize that my sister and I do not wish to put any pressure upon you. While we do feel that the time is right, and that you are an ideal partner in this endeavor, there is no need to rush. I am not exaggerating when I say that you could spend the next year with us, growing comfortable with our presence, and we would not consider it an imposition. You are doing us a great service, and the hospitality of our castle is the least we can offer in compensation.”

“And of course,” said Luna, “You are still free to change your mind.”

“No,” said Twilight Velvet, pushing her chair back from the table and standing from her seat. “I’m ready. I’m more than ready, actually…” She blushed, looking down at the tablecloth. “I’ve been spending the past two weeks looking at your beautiful bodies and I kinda need it tonight.”

“That’s wonderful to hear, Twilight Velvet,” said Celestia. She and Luna pushed their chairs back from the table as well - although they needed to push themselves quite a bit farther back, thanks to the enormous cock and balls that hung between their legs. The princesses took their dinner in the nude, Twilight Velvet had learned. They spent nearly all their time nude, in fact; once they were out of the public eye, their dresses came off.

It wasn’t as though their “masculine” assets were a secret, of course. No dress could conceal a ballsack that hung down to one’s ankles, or a cock thicker than the average pony’s waistline. But seeing them stride around the castle nude, displaying their bare bodies without a care in the world, was a privilege that most ponies never received. They were gorgeous, towering presences, standing at eight feet tall - which put Velvet’s eyes at the level of their immense breasts.

Velvet had spent the last two weeks at the castle, getting acquainted with the princesses whose child she had agreed to bear. Truth be told, she’d been unbearably horny the entire time; it seemed like every moment alone was spent touching herself, imagining what it would be like to be penetrated and filled by those enormous, beautiful cocks. Modesty, and a touch of nervousness, had held her back until now… but tonight she was ready. She wanted to bear the heir to the Equestrian throne… and she needed to get fucked by those giant royal cocks.

“Follow us to the royal bedchamber,” said Luna, “And we shall begin.”

The royal bedchamber was a grand room, with a bed big enough for at least five princesses, even though only two princesses shared it. Twilight Velvet had been there several times during the last two weeks; Luna and Celestia felt it would be instructive for her to observe their lovemaking, and Velvet had been a very eager student… once she got over the surprise of learning that the two princesses regularly fucked one another.

It made sense, though, in light of what they’d told Twilight Velvet when they first approached her: not everyone could handle getting fucked by an alicorn. Celestia and Luna could fuck each other freely, with no risk of harming one another… but if they became involved with a normal pony, special magic - and a degree of caution - was required.

“I suppose I should get comfortable,” said Twilight Velvet. She sauntered across the room, making her way between Celestia and Luna, and fell onto the bed. Striking a provocative pose, she gave the princesses what she hoped was a confident smile. “I’m ready,” she purred.

Celestia, returning Velvet’s smile, snapped her fingers - which was purely for show, since the spell she cast came entirely from her horn. Velvet’s panties, held in Celestia’s aura, slipped themselves down the mare’s thighs, tickling the sensitive skin as they descended her legs. Once they passed her ankles and drifted to the floor, Luna cast a spell of her own - and the rest of Twilight Velvet’s clothing - her dress, her bra, her stockings - simply faded away like mist.

“As we’ve explained,” said Luna, approaching the foot of the bed, “The magical preparations for impregnating you are no simple spell. We will be performing a ritual - although my sister and I will be handling the more complex aspects. Your role is largely passive… although you can help us begin by arousing our stallionhoods.”

Luna and Celestia hefted their weighty cocks and set them down on the bed, making the mattress shake. Velvet started with Luna, crawling over the bed and pressing her face against the flared tip. The deep blue, musky flesh of Luna’s cock was spongy and soft as Velvet rubbed her cheek against it. When she dragged her tongue across its surface, tasting its intoxicating flavor, it began to grow and stiffen.

“Ahh, I see that your affection for our cocks was genuine,” said Luna. “That is important, young Twilight Velvet. Your enjoyment is a crucial component of the ritual. The more powerful your arousal, the more easily your body can accept our immense alicorn cock… and the better our chances of success.”

“Well, I have good news for you,” said Velvet. “I have never been hornier in my entire life.” She licked at the head of Luna’s cock, wrapping her lips around the edge of the princess’ flare, running her hands over the smooth skin. She watched the shaft grow longer and thicker, the flesh expanding until it was nearly as large as Velvet’s entire body.

Velvet lifted her face from Luna’s cock, once she was confident it had achieved its full size. She crawled on top of Celestia’s half-erect shaft, draping her body over it so that her ass was up against Celestia’s chest and her mouth was kissing the rim of Celestia’s cockhead. Velvet embraced the huge shaft with both arms - humping it, rubbing her tits against the ivory-white skin, kissing the flare as it expanded. Her pussy poured with juice, wetting Celestia’s colossal cock as Velvet rubbed her marehood against it. The regal musk of Celestia’s cock filled her nostrils with each breath, and every pump of her hips sent sexual fire through Velvet’s engorged clit. She could have cum, easily, just by humping Celestia’s divine dick, but she held herself back. Her only goal was to get the princesses hard.

“Excellent, Velvet!” groaned Celestia. “You have made my sister and me wonderfully rigid, Twilight Velvet. There can be no doubt that you are the right mare for this job; you adore cock, don’t you?”

“It is clear that she loves cock, sister,” said Luna, laying a gentle hand on the white and purple locks of Velvet’s mane. She stroked her soft hair, scratching behind Velvet’s ears affectionately. “Look how her senses feast upon your stallionhood. She adores its beauty, she savors its taste, she basks in its scent… I have found a kindred spirit in Twilight Velvet, for she loves my sister’s immense cock just as much as I do.”

“And I was overjoyed to see the love she gave your cock, Lulu,” said Celestia. “Your great blue beast inspires fear in so many mares; it was wonderful to see how Velvet threw herself fearlessly upon it.”

“Twilight Velvet’s husband must be a lucky stallion, don’t you agree?” asked Luna.

“Very lucky, to have a wife who is so passionate,” said Celestia. “And very kind, to agree to let two massively endowed alicorns fuck his beautiful wife.”

The princesses observed Velvet’s behavior, watching for signs of hesitation. They’d made plans in advance to mention her husband; it was a sort of test, a final chance for Velvet to exhibit regrets or express second thoughts.

There was none of that. Twilight Velvet was completely in love with Celestia’s cock, kissing and stroking it as her pussy gushed over its surface. She was ready - and so the royal sisters nodded at one another, their horns illuminating with swirling light.

The class of magic known as a “ritual” was a type that most unicorns never learned. Few spells called for the structure of a ritual: spells too complex for a single pony’s mind, or too powerful to be channeled through a horn, were distributed into sigils or artifacts and then activated magically.

The bedchamber was already set up for the fertility ritual, with sigils discreetly scribed on the floor beneath the bed. All Celestia and Luna had to do was join their magic and set the ritual in motion. Power flowed into their bodies, each beat of their hearts pumping arcane energy into their colossal cocks. Twilight Velvet, her arms embracing Celestia’s shaft, felt the huge dick growing even bigger.

“Worry not, Velvet,” said Luna, lifting her expanding cock and dropping it onto Twilight Velvet’s back. “Even though our cocks are growing far larger, the rigid flesh lengthening and thickening to a scale beyond your imagination… have faith that your body will be able to accommodate our girth. The ritual’s magic will permit you to stretch and swell, so that you may feel and enjoy every magnificent inch of our mighty cocks.”

“I didn’t know you’d get… bigger…” moaned Velvet. “I never imagined that I would ever have so much meat inside me.” Celestia and Luna were slowly pumping their hips, grinding their cocks against the mortal mare who was pinned between them.

“Our cocks are the biggest in Equestria, and they’re still growing larger,” said Celestia. “And we will stretch your pussy over our cocks, filling you with hot throbbing meat… and then a thick load of extraordinarily potent cum. You will swell with our seed… and you will bear our royal child.”

“Mmmm, your seed…” Velvet moaned. “I have to feel your big, swollen balls…” She squirmed out from between the princess’ cocks and wriggled her way onto the floor, kneeling in the shadow of the royal sisters’ nutsacks. Celestia and Luna’s balls ordinarily hung down to their ankles, and now - swollen with the ritual’s magic - they rested on the floor. Velvet buried her head in the taut skin between Luna’s balls, moaning as she breathed in their fragrance. She dug her feet underneath Celestia’s balls, using her toes to tickle the underside of her big white scrotum.

“Oh, Lulu, dear,” said Celestia, placing her hand on her sister’s shoulder, “Look how Velvet worships your balls. Once again I must compliment the mare’s taste; I know better than anyone how good it feels to rest my head against your enormous nutsack, and Twilight Velvet seems to love it just as much as I do.”

“And her kisses are just as sweet, sister,” said Luna. “I can feel her soft lips against my scrotum, and there is such love in them… It must be agonizing for her, knowing that our balls house the potent alicorn cum she craves. Worry not, Twilight Velvet, soon you will be full of our seed.”

“Yes, soon we will fill you so full of our spunk that you will be more a balloon than a mare, Twilight Velvet,” said Celestia, shivering with pleasure as the soles of Velvet’s feet massaged her ballsack. “We two will release an ocean of cum into your marehood, and you will bear our foal.”

“Tia,” said Luna, “I believe I have stopped growing. My balls are swollen with cum, and my cock is aching to slip between Twilight Velvet’s lovely thighs and part the folds of her marehood. Shall we?”

“I believe we shall,” said Celestia. “Velvet, would you rise? Your affection for our nutsacks is much appreciated, but something greater awaits.”

Twilight Velvet crawled out from under the princess’ cocks and climbed back onto the bed, backing up to the headboard in order to fully take in the spectacle that stood before her. She’d been so enamored with the alicorns’ nuts that she hadn’t bothered to look up at their cocks… but now that she saw them, her cunt pulsed with need… and perhaps the slightest big of apprehension.

The princess’ cocks, in their natural state, were nearly as large as Twilight Velvet herself when they were hard. But now they were far bigger - so large that, standing upright, their tips overshadowed the heads of the two royal sisters. Even their long, spiraling horns didn’t reach as high as their cocks. And their girth… it was unreal. Wider around than Velvet’s shoulders, so big that it seemed more plausible fer her to go inside one of them than the other way around. And yet the thought of being penetrated by something so massive was still irresistibly appealing.

“I see that you are still fearless, Twilight Velvet,” said Luna, pushing her stiff cock aside so that she could see past it. “Now that our stallionhoods are at full size and our seed is at full strength, we will breed you, and our seed will mingle in your womb to produce the heir we desire. So… which of us would you have first?”

Twilight Velvet stammered, looking between the two immense cocks before her. One was a shining column of ivory, the other a pillar of moonlit blue. To be fucked by either one would be the greatest honor of her life. “Your majesties, I cannot possibly choose,” she offered weakly.

“Ah, Celestia, she does not wish to injure my pride,” said Luna, placing a hand against the shaft of her sister’s cock and caressing a thick, raised vein. “Your heavenly stallionhood is irresistible, and she surely would wish to have it first.”

“You are both too kind to me,” said Celestia, returning her sister’s affection and running her fingers along the thick blue medial ring of Luna’s cock. “Your regal dick is so grand that I am certain she desires it more.”

“Well, when you put it that way,” said Luna, smirking, “I suppose my cock is better than yours, dear sister. Very well, I shall fuck our Velvet first.”

“Goodness, Lulu, that ego of yours,” chuckled Celestia as Luna climbed atop the bed, her dick bobbing above Twilight Velvet’s head.

“I suppose I do have a high opinion of myself,” said Luna, using both hands to point her cock down at Twilight Velvet’s cunt. “But after I get done stretching your wet little pussy around my cock, I suspect you will think just as highly of me.”

Twilight Velvet spread her legs as far apart as they would go… but even that seemed insufficient for the girthy blue beast that drew closer. “Do I need to… do anything?” she asked.

“Just be your beautiful, fertile self,’ said Luna. “The ritual’s magic is empowered by desire, Twilight Velvet. So if you desire to be penetrated by my colossal blue stallionhood, fucked until you are delirious with pleasure, and filled with my potent seed… then you will be.”

“I do desire it,” breathed Velvet. “Please, princess of dreams, ruler of the night, fuck my unworthy pussy, breed me with your royal heir…”

“Well, if you absolutely insist,” said Luna - and she touched the head of her cock against Velvet’s wet lips. “Let me grant you pleasure so transcendent that not even dreams will compare. Your pussy will sing out in bliss, and you will become a creature of pure, perfect joy.”

With the tip of her cock resting against Twilight Velvet’s glistening pussy lips, Luna pushed her hips just a little further. It seemed impossible that any amount of force could get a cock that large inside a mare’s pussy - and yet, even a gentle push slowly parted Twilight Velvet’s lips. She felt her legs spreading further apart as Luna’s cock effortlessly widened her cunt and penetrated deeper into her body. “How soft you are,” moaned Luna, “And yet how tight… ah, deeper, deeper, I must go deeper…surround me with your love, Twilight Velvet, take all of me and be my broodmare…”

Twilight Velvet was pawing at the bedsheets, her chest rising and falling with heavy breaths as she watched her body become a huge gray cocksleeve for Luna’s giant dick. It was as though there was nothing inside of her that stood in the way of that colossal cock; the fertility ritual’s magic had turned her body into a stretchy instrument of pleasure, built to take a cock of any size. The more of Luna’s cock was inside her, the more of her body became a living cocksleeve - and every square inch of her velvet walls was a landscape of sensual pleasure. Wherever Luna’s cock touched her, Velvet felt fireworks… and with each passing second, it touched more and more of her.

“Oh, you are wonderful,” groaned Luna, gazing into Twilight Velvet’s eyes. “Your kisses were affectionate, my dear Velvet, but your pussy… it’s pure love, deep and warm and wet, surrounding me, embracing me… I’ll give you every inch of me, Velvet.”

Luna reached out with both arms and grabbed Twilight Velvet’s thighs, pulling the mare closer, impaling her inch by inch on her long blue cock. “Heavens, it is good to be this big,” groaned Luna. “If only Tia and I could do this ritual more often. We could stretch every mare in Equestria over our cocks, and sire a generation of future princesses… Ah, it would be great fun…”

A throb shot through Luna’s shaft - and Twilight Velvet’s body, stretched tight over Luna’s cock, throbbed along with it. The underside of the shaft bulged as fluid rushed through it, and a gush of thick precum shot from Luna’s tip. “Let me fill you,” moaned Luna. “Grow and stretch until I can all of myself inside you…” Still gripping Velvet’s hips, she straightened her arms, pushing the mare away from her and pulling her back. She repeated the motion, sliding Velvet’s body up and down the length of her shaft like the living cocksleeve she was. Her thick blue dick throbbed again and again, pumping more pre into Velvet’s pussy - so much pre that her body began to bloat. And she she swelled with pre, her body stretched further, becoming little more than a cock-shaped column of gray skin with two tits, four writhing limbs, and a moaning face at its tip. Finally, she stretched far enough that all of Luna’s cock was inside her.

“Oh, finally,” groaned Luna. “Everything before this moment was merely foreplay, Twilight Velvet. Now we fuck.” She pumped her hips, pushing and pulling Velvet’s cocksleeved body over her trobbing shaft. More precum spurted from her slit, progressively bloating the mare’s body as it filled her. Luna threw her head back, her mouth hanging open in a long, blissful groan and her enormous blue tits shaking with every thrust.

“Oh, Twilight Velvet, I cannot tell you how hard it was to restrain myself these past two weeks. How I wished to tear your dress from your luscious curves and part your marehood with my long, hard dick.” She pumped her hips harder, thrusting three feet of cock in and out, in and out of Velvet’s body. “We could not have chosen a more lovely, graceful mare to bear our royal foal… and how fortunate that that same mare is an admirer of our gigantic alicorn cocks.”

“Tell me,” asked Luna, “Tell me how much you want to be filled with my cum, Twilight Velvet.”

“I need it,” groaned Velvet, running her hands over her soft, bloated flesh. “When I kissed your ballsack, it was so big and so full of cum… I need you to drain those big blue balls into my pussy, I need to see how much my body can stretch…” Her legs twitched, her pussy clenching around the enormous shaft. “Please, Luna, breed me, fill me with your seed…”

“Well, Velvet, if you are ready,” grunted Luna, hilting Velvet repeatedly on her cock as she pistoned her wide blue hips. “Then here it comes…”

Luna yanked on Velvet’s hips, penetrating her with all six feet of her immense cock. There was a rumble like a distant earthquake, then the sound of thick, churning liquid - and then a fleshy throb shot through the length of Luna’s shaft. Power surged through Velvet’s body, and the rush of cum touched every inch of her stretched pussy walls, making them resonate with mind-melting pleasure. Velvet came - and since her body was basically one big pussy at this point, she was struck by a full-body climax, an orgasm that electrified every nerve.

And Luna came just as hard, shooting gallons upon gallons of thick, hot spunk into Twilight Velvet’s body. The load came hard and fast, unevenly bloating Velvet’s stretched skin. Each fresh geyser made her grow larger and rounder; her body ballooned, and her tits expanded, and the climax hitting her pussy in waves grew stronger and stronger. Velvet was used to orgasms fading in strength over time, but this one grew beyond what she would have thought possible. Along with the size of her body, her capacity for pleasure had expanded - and she was experiencing a climax better than most ponies could even imagine.

Twilight Velvet was still coming when Luna shot the last of her load and dragged her cock out of Velvet’s pussy. As the huge blue cock slid out of her, Velvet’s body returned to something like its normal shape. The structure of her body reasserted itself, and the huge load of cum gathered in her belly. As her climax finally receded, she put her hand to her overgrown tits and pressed her palm into her cum-filled belly. Her big, round belly, too big for Velvet to see past, made her look pregnant already… although she was far bigger than any normal pregnancy could ever make a mare.

“Oh, Luna,” moaned Twilight Velvet, “I can’t believe you made me so big… but I’m ready for more, I’m ready for anything… Celestia, please, come and breed me…”

“Actually, Velvet,” said Celestia - from somewhere Velvet couldn’t see, due to her enormous belly - “I’d like you to come to me.”

Velvet laughed. “I certainly would, your highness,” she said, “But your sister made me about five times heavier when she came inside me. I suspect I’ll be bedridden for quite some time.”

“Not so,” said Celestia. “Stand from the bed, Twilight Velvet; you will find it easier than you imagine.”

Twilight turned her body and swung her legs down from the bed - and once her feet hit the floor, she discovered that she was able to stand. She still felt enormous - but her belly wasn’t as heavy as its size would suggest. It was so big that it dragged on the ground, big enough that the rest of her body could easily have fit inside it - and it sloshed heavily with Luna’s load. But when she shuffled her feet, she found that she could gradually move herself forward.

“The ritual’s magic helps to support you,” said Celestia. “It would be no good if you were just lying helplessly beneath your cum-swollen belly, struggling to draw breath. And I would be pleased if you would remain standing, Twilight Velvet - I wish to enter you from behind.”

Twilight Velvet turned her body, pointing her backside at Celestia. “Well, go on,” she said, casting a sultry look over her shoulder. “Breed me, your highness.” She leaned forward, putting all her weight on her enormous round belly, and used one hand to reach back and pull open her slick pussy, exposing its glistening folds.

“Oh, young Velvet,” said Celestia, lifting her six-foot cock and advancing on the cum-swollen mare, “It was agonizing to step aside and watch my sister bury her cock in your fertile body… but she has made you so beautiful. I think I will enjoy fucking you even more, now that your body is so big and round.”

The tip of Celestia’s long white cock arrived at Velvet’s pussy lips - and, just like Luna’s cock, it parted her folds with only the slightest push. “Ah, heavenly,” Celestia gasped, as Velvet’s pussy embraced her shaft. “Twilight Velvet, we asked you to carry our heir because of your magical compatibility… the width of your hips… your experience as a mother… and it was just marvelous luck that you also happen to have a wonderfully tight pussy.”

“I’m honored to serve you, your highness,” Twilight Velvet moaned, groping her swollen tits. “With my life, with my body, with my slick, hungry pussy… I want to belong to you. Conquer me, rule me with your cock… And fill me with your fertile, royal seed.”

When Luna had fucked her, Twilight Velvet’s body had been forced to stretch around the entire length of the princess’ cock. Now that she had her big belly out in front, she could take the first few feet of Celestia’s cock without visibly stretching any further. But she was stretching on the inside; even though her marehood had just been filled by a cock of equal size, Celestia’s shaft felt tremendous, and being penetrated was so overwhelming that she would have collapsed to the floor… if her big, soft belly weren’t keeping her upright.

“Oh, Velvet,” gasped Celestia, “Years of waiting, searching, finding just the right mare to bring our heir into the world… every moment was worthwhile, just to feel my long, hard pillar of cockmeat in the embrace of your marehood.” She pumped her hips, fucking Velvet so deeply that the surface of her enormous belly distended with the shape of Celestia’s flared head. She worked herself deeper inside Velvet, fucking harder and faster as more of her cock slipped inside her.

Twilight Velvet draped her arms over her cum-bloated belly, feeling the skin beneath her fingers stretch as Celestia’s cock pounded deeper into her pussy. She felt something heavy smacking against the backs of her thighs, slapping and sloshing against her with each thrust. It was Celestia’s nutsack, she realized - the storehouse of all her wonderful, potent alicorn spunk. And if it was smacking her thighs, that meant Celestia was all the way inside her.

“This fertility ritual has made me so big, Twilight Velvet,” purred Celestia - who was now close enough to lean her body into Velvet’s back, resting her warm, soft tits against the the mare’s back. “So big and so full of cum. I suppose you know how that feels, now that Luna had filled you with her load… but while your body aches to be filled, mine years to be emptied.” Panting, she pumped her hips faster, hammering her cock into Velvet’s bloated body. “My alicorn nuts are so terribly swollen, so full of potent magical seed, and I desperately need to unload them… give me relief, Twilight Velvet, take my cock in your tight unicorn pussy and let me erupt inside you…”

“Tia, dear,” said Luna, sneaking up behind her sister, “Your talk of swollen nuts has reignited my passions. This damnable ritual is forcing my nuts to churn up another load, and if I do not seek another release, my balls may end up painfully blue. More so than usual. I don’t suppose you have room for one more, sister dear?”

“Always for you,” said Celestia. She widened her stance, clearing a path for Luna’s cock to enter her pussy. “Fuck me, Lulu. I’ll come twice as hard with your lovely cock pounding my cunt.”

Luna rested her cockhead against her sister’s pussy lips - which, given the size of her cock, meant standing six feet back front her - and practically charged forward, hammering two feet of dick into Celestia’s cunt with one motion. With Velvet, she had taken it slow… but Luna knew that Celestia could take a pounding, and she wasted no time. Soon she was fucking Celestia harder than Celestia was fucking Velvet… but Celestia was not to be outdone, and she gradually accelerated the pace of her thrusts. Soon they were in perfect rhythm, and the force of both their massive cocks was pounding its way into Twilight Velvet’s body.

Velvet was swimming in bliss, pounded by thrusts that hit her pussy like tidal waves, resting upon a bloated belly that wobbled like a waterbed as six feet of alicorn cock slammed into her again and again. Groans turned to cries as the tension in her pussy reached astronomical heights, becoming a white-hot star inside her… and then it burst, releasing thundering pulses of pleasure through her body, rippling through every delighted nerve ending, making her pussy clench tight around Celestia’s thrusting shaft.

It was Luna who came next, groaning and gushing, pumping a fresh load of spunk into Celestia’s cunt. And Celestia, caught between two climaxing lovers, joined them in rapture. Her pussy throbbed and clenched, and that orgasmic release rode the length of her shaft, deep into Velvet’s pussy… where it erupted in a ceaseless gushing burst. Velvet shuddered, her cries catching in her throat as Celestia’s thick royal load bloated her even bigger. Her tits swelled until they were bigger than Celestia’s, and her belly - already so big and so wonderfully round - expanded further with each colossal gush. Velvet felt herself being lifted higher, held aloft by the wobbling, sloshing belly beneath her.

Velvet must have been ten feet off the ground when Celestia finally pulled out. Her belly was a waterbed, and the waves of cum within it gently rocked her body as climax gave way to afterglow. “The ritual is complete,” said Celestia, placing her hand on Twilight Velvet’s bloated tummy. “Our seed has mingled, and you will bear a child who is both mine and my sister’s.”

“In time,” said Luna, “Your belly will reach a more manageable size. But for now, Twilight Velvet, you must merely rest. Your comfort and health will be our priority in the coming months… and we will strive to adequately convey our gratitude.”

Twilight Velvet sighed happily, feeling her eyelids grow heavy. “I should be thanking you,” she said, stroking the skin of her bloated belly. “You’ve given me more than I could have dreamed…”
