An Astrophysical Convergence

An Astrophysical Convergence

“My sister, you can’t be serious….”

“We are perfectly serious, Celestia. It would be in the best interest of Equestria. Given the dangers we face it’s essential to have strong warriors to ensure our security in the future.”

Princess Celestia shook her head and sighed. They had just spent most of the day helping a distant village recover from a rogue dragon attack, and then when they returned Luna had started insisting on the most ludicrous idea Celestia had heard in centuries. She understood well why her sister was making this idea, and agreed that the security of Equestrian was a problem, but the solution was very far-fetched. Out of everything they could dedicate their powers to doing, Luna’s master plan was for the two of them to...make foals.

“Absolutely not. We’re sisters, Luna, we can’t have foals together. Besides, how would we even accomplish that?”

“A few well placed spells would suffice. Regardless, our relation is irrelevant. Together we have some of the most powerful magic in existence, and my idea is the best way to combine our abilities. As a bonus, it could even be fun…” Luna’s voice trailed off as she took a moment to eye her sister’s flank, which was quite noticeable even from the front thanks to its profile.

Celestia bit her lip of the idea of her sister possessing something extra, and promptly rutting her with it. It didn’t help that there was a nagging heat in between her legs that was constantly prodding her mind to bring dirty thoughts to the forefront. How long had it been since she had a proper rutting?

“Uh-huh. Assuming I somehow decided to go along with this mad scheme, who were you planning on being the “father”?”

Luna seemed to be deep in thought as she paced a circle around Celestia, eyeing her in an almost predatory manner. “Well. I suppose we could have a drawn out competition to see who would fulfill the role. Although I’m perfectly willing to volunteer.”

“So you want me to be the mother then?”

“Well, you are already in heat afterall~”

Celestia blushed lightly due to her sister’s realization. Luna’s suggestion was becoming more tempting the more that Celestia stopped to consider it. A child created between the two princesses would be extremely powerful, and would undoubtedly grow up to be a champion of Equestria. On top of that, she had always wondered what it might be like being a mother. It certainly couldn’t hurt to try, could it? To top it all off, she’d get to experience a big,thick, throbbing…

“Distracted, Tia?”

Smack

Celestia gasped and jumped as Luna’s hoof made hard contact with her flank, sending her copious cheeks bouncing and jiggling out of control. Her mischievous sister simply snickered as Celestia turned around and gave her a slight glare.

“Getting a bit eager aren’t you, Luna?”

“My apologies, sister”Luna responded with a slight grin,”But it seemed the quickest way to recover your attention. Have you made a decision? “

Celestia nodded, “Y-Yeah. I think...uhhh….fuck it, let’s give this a shot.”

She was barely able to finish her sentence before Luna moved forward and pressed their muzzles together. After a quick gasp of surprise Celestia could feel Luna’s tongue force its way into her maw, wrestling down her own tongue in an impressive display of dominance. Celestia quickly gave up on any resistance, even giving out a few light moans as her sister passionately made out with her.

“I knew you’d make the right choice, sister” Said Luna with a wide smile, “Now let us not waste any time. Turn around and give us proper access to that supple rear of yours.”

Celestia quickly found herself blushing again. “W-What? Right here? But what if somepony walks in and sees us?”

“Then they shall get a fine show,” Luna’s reply came in an almost purr-like voice as she walked behind Celestia to get a better view.

And what a view it was…

In front of Luna was a positively glorious and massive flank. Two unbelievably plump and rounded plot cheeks sat atop Celestia’s legs, each one slightly larger than a beachball even. The fleshy globes jiggled ever so slight as their owner trembled. There was more to Celestia’s figure than just her rump though. Her rear was complemented by wide, motherly hips and some of the most full, luscious thighs Equestria had ever seen. Celestia had certainly put on a lot of weight over the years. However, it wasn’t her weight that she was known for as much as the way she carried it. Whether due to her Alicorn biology or some crafty spellwork, Celestia carried all her extra weight in the perfect places. There was no other mare in Equestria who could have an otherwise slim figure but maintain such massive hips,thighs, and flank.

It didn’t take long for Luna’s restraint to break down, and soon she found herself walking up to her sister’s ass and wrapping her hooves around both sides of it. It wasn’t until she could barely reach both of Celestia’s cutie marks that she realized how truly large this flank was. She also couldn’t help but revel in the pleasing sensation of how far her hooves sank into the soft flesh. Soon she was rubbing, squeezing, and groping Celestia’s flank in a shameless manner.

Celestia wasn’t sure if she should be embarrassed or proud at the amount of attention her flank was currently receiving. Although it didn’t take long until Luna was able to entice a few light moans from her as those hooves deftly groped her soft and sensitive rear.

“For shame, Tia. Just how much of you been eating to get such a vulgar figure?” Luna spoke in a mocking tone, but the arousal in her voice was unmistakable.

“Perhaps I’m just naturally blessed with it,” Celestia retorted, “Why do you ask, Luna? Jealous?”

“My dear sister,” Luna replied, “I don’t envy your flank, I crave it,” She emphasized her point by giving Celestia a hard spank and sending her cheeks jiggling like an ocean of jello. She practically purred as she nuzzled that soft, cushioned rear and continued groping it. “This is quite fun, but perhaps it’s time to take it to the next level. “

Celestia heard the tell-tale sound of a spell being cast and turned around to see quite the stunning sight. Luna had just used magic to equip herself, well equip herself. In between Luna’s legs was a massive member, already over a foot in length and growing larger as its owner began to stroke it with one hoof. Beneath that massive shaft hung two equally massive testicles, each one nearly the size of a basketball and undoubtedly full of powerful seed.

Celestia gulped, “A bit excessive don’t you think, sister? That’s a fair larger than anything I’ve ever taken….”

Luna smirked, “I’m certain you’ll adjust. Besides, it’ll only increase the chances of successful breeding.” With that Luna approached Celestia and slipped her length in between her two prodigious flank cheeks. She couldn’t help but grown as Celestia’s massive rear clenched and trapped her new cock inside the near cavernous crack. It was impossible for Luna to resist moaning as every new jiggle and bounce of Celestia’s ass stimulated her shaft.

Luna wasn’t the only one enjoying herself though, Celestia began to shake more and more with anticipation as Luna’s length was hot-dogged in between her gigantic globes. “Mmhh...Luna, stop teasing me and get on with it,”she whined.

Luna replied by giving Celestia’s rear a hard smack, “I’m just getting ready. Keep shaking that fat flank and we’ll be starting real soon.”

Soon Luna’s member was throbbing at full length, an impressive 19 inches of stallion. She promptly mounted Celestia and lined it up with the intent of finding and penetrating Celestia’s marehood. She began to slowly push her hips forward, thrusting her cock in between her sister’s plot cheeks. A light groan emerged from her lips as more of her length was lost inside the ocean of soft flank. To Luna’s shock, she had already pushed nearly half of her shaft in and still hadn’t reached Celestia’s marehood.

“What’s taking so long, Luna?” Celestia asked with curiosity, right before she felt something hard pressing against her wet slit. There was barely time to gasp before the pressure intensified and Luna’s thick member was forcing its way inside of her, forcing her walls to spread wide with its impressive girth. “Ooooohh...Luna…”

“Mmmh. Hold tight, dear sister. You haven’t taken all of me yet” Inch by inch Luna continued to stuff Celestia’s entrance full of her shaft. By the time she had hilted herself the tip of her cock was pressing right up against her sister’s cervix. It was a mind-blowingly tight fit, but a fit none the less.

Luna was in heaven, the sensation of having half her member trapped between Celestia’s cushioned flank and the other half deep inside her marehood was almost overwhelming. It took all of her willpower to start thrusting at a slow and steady pace instead of just rutting away like a wild animal.

Meanwhile Celestia could hardly believe the situation she was in. She would have never pictured herself standing exposed in the throne room, getting pounded by her own sister. It was like something out of her dirtiest fantasies. It was a fantasy she was happy to give herself over to though, she pushed back her hips and moaned every time Luna’s hard member rammed into her tight slit. Each impact sent her heavy flank jiggling and bouncing like an ocean of pure jello.

“Such a bountiful, motherly figure. You’ll make the perfect broodmare, Tia” Luna teased as she began to put more power and speed into her thrusts. All the while she was being treated to an amazing show as Celestia’s ass was in constant movement with waves of jiggle. The massive cutie-mark suns that stretched across her sister’s rear made perfect targets for Luna to spank. “I do hope this rump of yours keeps growing once you get pregnant. Although we may have to expand the throne…”

Celestia could hardly imagine her flank becoming even larger. She was already the most voluptuous mare in Equestria. However, she couldn’t deny the perverse appeal in brought to consider the possibility of her plot becoming even bigger and bouncier than it already was. The evidence of her fantasizing was noticeable, as she began to pant heavier and her marehood became even more lubricated than it already was.

“That’s right, sister. Take it like a good, submissive little broodmare. Mmmh, I’m going to put so many foals in you,” Luna began to increase her pace even further, causing her heavy balls to slap against Celestia’s cushioned thighs. The two massive testicles were practically churning with strong, virile seed. Her member began to throb harder and faster as Celestia’s tight inner walls clenched to massage her extensive length.

Celestia blushed heavily at being called a broodmare, but she was receiving such overwhelming pleasure from the large cock ramming her that she wasn’t able to form anything more complicated than pants and moans. Her senses were being overwhelmed by the feeling of her copious flank flesh jiggling and the deepest parts of her inner walls being plowed. All she could do was pant like a mare in heat and instinctively shove her hips back while tightly clenching the inner muscles of her marehood.

“Oooooh...keep it up, Tia...it won’t be much longer at this rate.” Luna groaned as she began wildly thrusting in and out, humping her sister with reckless abandon. Every moan that Celestia made, every bounce of her flank, and every clench of her inner walls encouraged Luna to go faster and harder. She could feel her heavy balls slowly tightening up, like pressure building behind a dam. She was just barely holding on, but it was only a matter of time before the dam would burst.

Celestia’s moans became louder and louder as Luna’s thrusting became faster and more erratic. Celestia could barely process the amount of pleasure she was receiving, she could feel every inch of that thick rod inside of her as well as every hard throb it gave off. Every pump of her sister’s hips was bringing her closer and closer to the edge. She bit her lip and braced itself, knowing that it was only a matter of time before Luna started blasting her massive load into her.

“Nnnnnng...sister….I can’t hold back…” Luna was on the edge, she could feel it. Her cock throbbed almost painfully hard while her balls continued to slosh with their heavy load as they began tightening inside their sack. She gripped Celestia’s wide flank with both hooves and began to plow into her with as much power as her muscles could muster.

And then the floodgates opened…

The pressure started at the base, only to move forward as the head of Luna’s shaft flared open to begin spraying a wide torrent of seed straight into Celestia’s fertile womb. That was only the beginning though, as every pump of Luna’s hips resulted in another wave of sperm spilling out deep inside of Celestia’s body. It became an automatic action of thrusting in and out as she worked hard to empty her massive testicles.

“Oooooh….Luna….it’s so much….” Celestia moaned and panted heavier than before as she felt the sheer volume of seed being pumped into her. Already her womb felt filled to the brim and Luna was continuing to spurt more and more batter into her. It wasn’t long before she felt her belly begin to swell slightly, growing a bit larger with every wave of sperm that was released into her.

Throb. Spurt. Throb. Spurt. Throb. Spurt

It was like a mechanical rhythm as Luna worked to breed her sister, with endless amounts of virile cum being unleashed into Celestia’s fertile womb. Her impregnation became more certain as each pump caused her midsection to grow larger and rounder as it worked to hold the incredible amount of fluid being released into it. It was already the size of a basketball, and continued to enlarge and become more taut as the onslaught continued.

Throb. Spurt. Throb. Spurt. Throb. Spurt

The room was filled with the two sisters’ moaning and lewd slapping sounds as flesh collided and sexual juices escaped to the floor. Celestia could only brace herself and enjoy the ride as her belly continued swelling to unprecedented sizes. It was now large enough to push her legs apart slightly and make her look beyond pregnant. The sheer amount of seed now inside of her was unbelievable, and Luna was still going! How much more could she possibly be holding?

Luna panted heavily as she continued to instinctively thrust in and out. Her balls were starting to feel lighter, but she knew there was still a little bit more baby batter to put into her sister. After a few more final spurts she pulled out of Celestia’s slit, allowing a copious amount of cum to spill out on to the floor, adding to the already large puddle of sexual fluids.

The two collapsed next to each other in a heap, breathing heavily as they recovered from their intensive mating. Celestia’s eyes went wide as she looked at how far out her belly had swollen. It looked very much like an over inflated beach-ball, it jiggled and sloshed as she pressed it with both her hooves. Feeling all that seed moving around inside her inflated womb made Celestia shake with a perverse sort of excitement. “My goodness, Luna. You made me so huge.”

Luna nuzzled her sister and smirked. “You think you’re big now? Just wait until the foals start growing.” She then laid down on Celestia’s squishy belly and sighed contently. “You’re the best, big sister.”

Author's Note

This was just a short little story to get me back into the flow of writing. To be honest, it didn't turn out fully as I wanted, but hopefully some people will find it entertaining.

I'm tossing around options for my next story, and I'm even considering ask for requests, but we'll see how this gets received first.

The Solstice is Nigh

“Alright, easy now. One step at a time. Be careful, you can do this. “

Princess Celestia grunted and panted as she made her way through the halls of the Canterlot. Her afternoon strolls had become increasing difficult as her pregnancy progressed. What had started as a small bulge in her belly had eventually ballooned to a taut basketball, and was now bigger than a beach ball. She had to spread her back legs far and wide in order to accommodate her swollen womb, which was packed with no less than four large foals. When she first agreed to have children with Luna, solely for the good of Equestria of course, she had no idea how virile her sister was. She sighed as she rubbed the massive swollen dome with one hoof. “Well, at-least we’ll have a strong dynasty now.”

Despite being swollen up larger than any mare before her, there were a lot of perks that came with the new situation. The entire country was now in a buzz about the news of four new royalty about to be born within the next few months. That meant Celestia was able to indulge herself in festivities, fine feasts, and other luxuries even more than she’d usually be able to. On top of it, Luna had taken it upon herself to do more and more of the workload, giving Celestia even more time to relax.

Too much relaxation came with some side-effects, however, as Celestia was reminded as she went to enter her personal quarters and found her hips brushing against both sides of the doorway. All that extra food she’d been eating hadn’t just gone to feeding the growing foals, but also found it’s way into all of her curves. Her hips, which could have already been described as “motherly” before she became pregnant were now the embodiment of fertility. Four foals would seem like an impossible task for most mares, but for Celestia it would be very achievable What grabbed the most attention, though, was her flank. It was already the bounciest, plumpest, rear in all of Equestria. Now it was that and then some. Her backside usually meant the end of any chair she’d try to sit on, and she already had to order a larger throne as her plot cheeks plumped bigger and wider in response to all the new calories she was taking in.

She heaved herself on to the bed with a sigh, and promptly glared as the piece of furniture groaned in response to her weight, “Curse you, I don’t weigh THAT much….”

There was a giggle from the doorway, “Putting curses on the inanimate objects now, are we?” The source of the giggling was soon revealed to be Luna, who was the cause of both Celestia’s dilemmas and her pleasures as of recent.

“Oh..um..just letting out some frustration is all”

“Mhmmm” Luna smiled approvingly as she made her way over to Celestia’s side and took in her sister’s maternal form. She began to rub her sister’s massively swollen belly with both hooves while smiling up at her. “So, how’s our favorite sister been?”

“Other than feeling like an over inflated balloon, I’m alright. Although it’s hard to stay focused on anything when you’ve got four foals kicking around inside of you.”

“Is that so?” Luna looked over Celestia’s middle with curiosity as she began to rub a bit more intently, feeling up every inch of her belly’s slopes. She could feel her heart flutter slightly as she felt a definite kick against the edge of Celestia’s womb, and then another a few seconds later. Meanwhile Celestia herself began to moan lightly thanks to Luna’s administrations.

“Enjoying yourself?” Asked Luna with a smirk.

“You have no idea. This belly rub feels like heaven after carrying around this giant dome all day.”

They spent a few moments like that, with Celestia gratefully enjoying the tender belly rub she was receiving from her sister. Then Luna began to get a bit more creative. She stretched out her hooves to the limit and managed to grab hold of Celestia’s belly from both sides. She then gently rocked it back and forth while holding her ear up to it and enjoying the sounds of sloshing amniotic fluid and swimming foals kicking against the walls of their mother’s womb. Luna was still in awe of this whole situation. To witness her sister’s fertility in action, and to be the “father” of her children on top of it.

“Now who’s enjoying themselves?” Asked Celestia in a cheeky tone.

Luna blushed, not realizing how distracted she became, “Heh...sorry sister. It’s just not hard to get entranced by your new figure..”

Celestia smirked, “Do tell more.”

Luna smiled in response, having played this routine before. “How could we not be distracted by such a form? After all, you have the biggest, most rounded womb in all of Equestria. A true display of superior fertility. Not to mention the most motherly hips any of us have ever seen, topped off with such a...prestigious flank.” Luna smiled lecherously at the end of that sentence as she grabbed large hoof-fulls of Celestia’s plump flank; squeezing and groping shamelessly. She couldn’t help but smirk as Celestia squirmed with arousal. Speaking of arousal, she was beginning to feel her own flare up along with a throbbing between her legs. She could pounce Celestia and rut her right now, but it would be so much more satisfying to let the lust build first.

“And let us not forget the newest feature,” Luna smirked as she made her way lower to gaze upon Celestia’s burgeoning breasts. They had swelled rapidly since the onset of her pregnancy, and now resembled two plump melons. There was no doubt that the two mounds were filled to the brim with milk for their upcoming children. It was so tempting to lean down and suckle from those supple teats, but she restrained herself. That milk would soon be required by some very needy foals.

However, there was something much more naughty Luna COULD do to those delightful breasts. She reared up slightly and slowly slid her quickly hardening and lengthening member in between Celestia’s tits, enjoying their soft and squishy embrace.

“Oh my, sister...what are you…?” Celestia struggled to see over her massive belly before she realized what was going on, “Oh you naughty little Parasprite…” She responded to this realization by bringing her legs closer together and tightening the hold her breasts had around Luna’s shaft. Luna promptly groaned in response as she began to slide in between the milk jugs faster and more fluidly.

Celestia could only pant with growing anticipation as she felt that big, meaty shaft throb in between her breasts. She longed to feel it deep inside her once again. Despite already being pregnant, she just couldn’t get enough of having Luna’s seed pumped deep inside of her. “Luna, you tease me too much. I know you’re having fun, but isn’t it time for the main course?”

“Patience, my dear sibling,” Luna replied as she gave the side of Celestia’s right flank a heavy smack, watching with delight as it jiggled in waves. “I need time to take in this glorious sight and get prepared”. With that she re-positioned her member near Celestia’s wet slit, prodding and rubbing against it to get her rod lubricated. Beneath her member she could feel her balls churn with a heavy load of seed. Of course, there was seldom time when they weren’t. Luna had been forced to boost her production heavily to keep up with Celestia’s hormone boosted sex drive.

Celestia grabbed hold of the bed sheets and spread her legs wide, getting herself prepared for Luna’s size and usual roughness. Not that she was afraid though, she couldn’t be any more excited. After all, there was nothing like a good rut from her sister to distract her from the growing pains of such an extreme pregnancy. There was also a bit of fun added by the suspense. Since she was unable to see anything except her big, white dome of a belly, there was no way to know just when Luna was going to penetrate her. At-least, not until she felt a building pressure at her entrance, followed by the intense feeling of her marehood’s lips being parted and her inner walls being forcibly spread by the girth of Luna’s cock.

Luna let out a long, loud groan as she pushed her shaft all the way in to the hilt. She then smirked down at Celestia as she readied herself to begin thrusting, “Better hold on tight, sister. I don’t know if the bed will hold out this time~” Luna than shifted her hips back before eagerly plowing forward, smirking as the bed whined from the combined weight of herself and Celestia pressing down. She then began to repeat the process over and over, being rewarded with the rich lewd sounds of their hips slamming together. What was even more rewarding was the way that every thrust rocked Celestia’s body, sending every voluminous part of her figure bouncing or jiggling. Her massive,gravid womb bounced gently forward and back, with her heavy teats slapping against the underside of it. Meanwhile her plump thighs and heavy flanked jiggled in connected waves, cushioning Luna’s heavy thrusts.

Luna leaned down to gaze happily into Celestia’s eyes, panting with pleasure as she began to thrust even harder and faster. “Mmmh, you’re so amazing, sister. Truly the most fertile mare in the land. With the largest, most motherly figure on top of that. Your hips and posterior are almost wider than the bed, and that belly of yours could almost serve as a small chair~”

Celestia blushed even deeper than before, moaning passionately as her sister rocked her world in more ways than one. “Are you sure about that? Maybe you can get me even bigger the next time, can’t leave any records un-toppled after all”

“Now there’s a thought,” replied Luna in a husky voice. Her cock began to throb even harder as she imagined what Celestia would look like if she had an even more fertile form, and was laden with even more foals. Just the thought of filling Celestia full of more and more offspring drove the more animalistic parts of her wild. She began putting all of her power into pounding away at Celestia’s slick snatch, ruthlessly plowing her with abandon. She imagined her sister’s belly swelling bigger, and bigger, and bigger. She’d be so large and fertile that any other mare would drop with envy.

The bed creaked and moaned as Luna pounded away at Celestia like a feral animal. The sounds were only contested by Celestia’s wild moans and screams of pure pleasure. She couldn’t do anything more than hold on and enjoy the ride as Luna’s rod slid in and out at such a heavy pace; along with her large,heavy balls slapping hard against her soft rear.

“Hold on tight, sister. Mmmhh..not much longer now~”

It was their most intense rutting yet. Luna’s shaft throbbed hard and eagerly while Celestia’s slick inner walls clenched ever tighter, as if trying to milk Luna of all her seed. It was seed the Luna was eager to provide, as every erratic thrust made her testicles ache for release. Meanwhile Celestia began to scream louder and louder, until she finally screamed Luna’s name in pleasure while her marehood clenched up tight as can be.

“Ohhhhh, Luna!”

“It’s coming, Tia!” Luna tightly held Celestia in place as she finally began to release her pent up load, spurting thick cup fulls of splooge deep into her sister’s tunnel. Then another, and another. Celestia could only squirm with ecstasy as she was pumped full of the same foal batter that left her so unbelievably pregnant in the first place. However, she couldn’t help but feel a warm contentedness as Luna emptied nearly immeasurable amount of seed into her, but was surprised as Luna’s thrusts began to slow down.

“Finished already, Luna?”

Luna smirked, “Not nearly, but I had an idea” she then slipped her cock out of Celestia’s snatch before taking aim and shooting out heavy streams of sticky fluid over Celestia’s body. She worked to coat every inch of Celestia’s ample curves with her seed before collapsing next to her sister and panting heavily, “That was….quite excellent….sister.”

“Easy for you to say,” replied Celestia,” “You’re not the one who has to deal with that in your fur. But I’ll forgive you, if you’ll help me with the bathing~”

“I’d be delighted.”

Finally got around to posting chapter 2. I feel like tackling a 4th story soon, but I'm not sure what. I'll probably make a blog post with a poll to see what people would be most interested in.
