Shining Armor hummed softly to himself, the tune was some half remembered marching song from his days in boot but it hardly mattered, all he wanted was something to fill the quiet of the bathroom as he pissed. He sighed, relishing the sensation of his bladder finally emptying as the cool porcelain seemed to slowly bleed away the heat that had soaked into his very bones. His cock had grown larger than ever, making the position he was forced into an awkward one with one hoof on the lid of the toilet while another was on the back. Still, it got the job done, and after a good few bars of the marching tune his bladder was empty and he wasn't quite as hot.

Hopping down, the stallion turned and quickly washed his hooves, smiling softly as his gaze lingered over the five toothbrushes all nestled in a single jar at the edge of the sink. Things had progressed quite a bit over the last few months, and though he was still rather surprised by the whirlwind of activity he had found himself in, he had to admit it felt nice, right even. They were a strange family, but a family nonetheless, and their massive six pony bathroom was evidence of that.

The stallion shut off the water and briefly rubbed his hooves down with a cloth before landing with a smile, back on the floor. A peel of laughter could be heard from the room beyond, making Shining Armor smirk as he recognized Luna’s trademark cackle.

Pushing open the door, Shining Armor took a moment to simply stand there, leaning against the door jam while he gazed out over the room. To the right, his sister levi paced, which happened when one could no longer walk and was forced to self levitate in order to fulfill her desire to pace without actually being able to use her hooves to do so.

The mare herself had been particularly susceptible to her cravings and gained a considerable amount of weight not solely due to the foals growing inside her. Her belly was massive, though not quite as large as Celestia’s, Twilight’s foal filled belly easily dwarfed Luna’s more trim body, and was just a few inches smaller than Cadence’s titanic body. The sheer amount of foals growing inside her made walking nearly impossible, add to that the extra padding she had put on and Twilight’s hooves could barely even touch the ground anymore.

The rest of her had grown in proportion to her, with breasts easily large enough to feed over a dozen foals, and rounding out to roughly the size of a full grown pony, each. The purple alicorn had long since thrown her diet to the wind and had fully embraced her desires and as such her thighs and flanks had grown to truly enormous proportions. Shining Armor remembered vividly the way his body could sink into those delicious flanks of hers, only barely able to penetrate the mare and still see over her backside at the same time. Other then that her form had considerably filled out, with her cheeks, neck and the rest of her body gaining more definition.

While she floated back and forth in front of their shared bed, she nervously bit her lip before popping a cookie into her mouth and chewing. This repeated a few times, and though he was slightly worried by the odd expression she had on her face, something told him that her pacing was the product of just thinking about something deeply, rather than stress.

Luna was the next closest, the mare holding a comic book she was reading at the edge of their massive shared bed. The dark alicorn was laying on her belly, a wide smile on her face. Noticing the return of her mate, the alicorn lifted her attention and nodded to the unicorn, who nodded back with a smile. Shining Armor watched as she turned her attention back to her comic, his eyes drawn down her massively gravid form.

She had grown significantly over the last several months, but had not indulged quite like the rest of his mares had. Though she had gained a little definition to her body and lost a little of the muscle she had before, she was easily the trimmest, and was the only one of his mares that could still walk without assistance. Which meant that her belly was incredibly firm, making the small movements of the foals within easily visible, something both of them had grown to love.

There was one thing that stood out though, and that was how her breasts had grown far larger then even Twilight’s, despite being pregnant with the least amount of foals. They were each as large as a full grown adult stallion and then some, and constantly leaked milk, necessitating the use of one of the milking bras that Twilight had whipped up. Something she wore even now, though she had changed the initially bland bra to deep blue to better fit her coat.

Beside her were the largest of his mares, who were both taking up a good chunk of the bed, their lips locked in the heat of rather intimate make out session. Celestia was the largest, with breasts easily two to three times bigger than Shining Armor’s entire body. Their massive size made it necessary to specifically craft her a bra that could grow with her while keeping up with her titanic milk production. When not wrapped up by a bra the massive mammaries easily excreted a constant flow of milk at the speed of a half open tap. What was far more impressive than even her unparalleled tits was her truly enormous ass, the size of which could probably smother Shining Armor if she ever sat on him.

The celestial mare made no excuses for her wanton gluttony and easily ate more then both Luna and Twilight combined. This had the effect of significantly fattening her up, and adding to an already massive stomach that was nearly twice the size of the rest of her body. Her hooves had long since been unable to meet the floor and by now she was so large that she couldn't use any doors or even some smaller rooms. Her sheer weight made it necessary to reinforce everything with both mundane and magical means, just to ensure she didn't accidentally fall through the floor or destroy another bed. She also had the most foals within her womb and even through the padding on her belly Shining Armor could see movement just beneath as their foals twisted and turned inside their mother’s swollen womb.

The mare on the other end of Celestia’s lips was not quite as gravid, though was still easily the second largest of Shining Armor’s mares. Her breasts were each easily larger than Shining Armor’s entire body, and had a milk production to match the size. Her bra was the same pink as her fur, and the massive peice of clothing had grown tight over the last several days, signalling that she would need a new pair soon. Her legs had also long since said their goodbye to the floor, as her stomach had made it impossible for her hooves to touch the ground with even the utmost straining. Though she hadn't started out this way, Cadence had grown as ravenous as Celestia, and thus had gained a considerable amount of mass to her gravid body. This had the effect of giving her an ass large enough to just about smother Shining Armor whenever he mounted her.

The mare brought a hoof to Celestia’s chin, leaning forward as much as she could and deepening the kiss before pulling back, their lips parting, a small thin line of spit connecting them. She smiled faintly, before pressing her lips forward one last time, adding a final peck on the solar alicorn’s mouth before pulling back.

“I do believe our Shining Armor is back from his piss.” Cadence remarked.

Celestia giggled. “I do believe he is, and I think that cuddling with him would be a most delicious prospect wouldn't you agree?”

“Most definitely.” Cadence agreed.

Shining Armor rolled his eyes and relaxed his body, letting his wife’s magic lift him up, while Celestia lifted herself with her own magic, placing her gravid form beside his wifes and leaving just enough room for him to slide in between them. His body now wedged between his wife’s and one of his lover’s bellys, Shining Armor shook his head and laughed.

“You two are so predictable.” He muttered.

Celestia shrugged. “We just like cuddles, is that so wrong?”

Shining Armor rolled his eyes. “Of course not, I’m just teasing you.”

The stallion wiggled into a better position, taking turns nuzzling one belly then the other, earning him alternating coos of pleasure from each of the massively gravid mares. As time went on and several minutes passed, he started to feel a little cramped and looking down made him realize the little room between his wife and lover was now gone. Raising an eyebrow, Shining Armor was about to brush it off as one of them just leaning a little closer to him, but if he focused he could feel their stomach’s slowly expand, pressing against him as they grew in real time.

He was about to say something when he noticed Luna abandon her comic book and waddle across the bed, taking a spot next to Celestia and leaning against the larger mare. Shining Armor sighed contently, feeling a sense of peace wash over him, or at least tried to, before Twilight Sparkle began levi pacing in front of him.

With a frown on his face the stallion stood up. “Why don't you come relax next to Cadence, Twilight? I’m sure whatever your fretting over wouldn't mind being put off for another minute or two.”

The purple alicorn stopped, and sighed. “Sorry Shiny, I just can't seem to relax.”

“What's wrong dear Twilight?” Luna asked, raising an eyebrow.

Twilight shook her head. “Nothing is wrong, in fact this is kind of good but…” She bit her lip. “It is certainly strange.”

“Back up, what exactly did you find out?” Cadence asked.

“Haven't you wondered why we seem to get more and more pregnant?” She pointed out.

Luna tapped her chin. “That is a little odd, but alicorn physiology is… odd.”

Celestia glanced down at her sister. “Wait, so you girls haven't figured it out yet?”

“Figured what out?” Shining Armor responded.

“Do you mean…” Cadence’s eyes lit up. “Ooooh this is so great! I just assumed that what was happening but to have it confirmed!” The pink alicorn squealed in delight, clutching her massive belly in both forehooves.

“Confirm what?” Shining Armor asked, scratching his head.

“Yes, I am most perplexed.” Luna added.

“The more we engage in intercourse with Shining Armor, the more pregnant we get.” Twilight pointed out. “Which explains why we are pregnant with a combined seventy nine foals.”

Shining Armor’s jaw fell open, Luna gasped, Cadence squealed in delight while Celestia merely shrugged. “Seventy nine.” The male whispered, his eyes glazing over.

“I had assumed we had hit eighty already.” The solar alicorn remarked.

“How many do we each have? The last test we did was months ago.” Cadence asked giddily.

“Celestia is pregnant with twenty five foals.” Twilight started, noticing the hint of pride that spread across the solar alicorn’s face. “You are pregnant with twenty one.” The purple alicorn pointed out, much to Cadence’s delight. “While I am pregnant with seventeen of Shining’s foals and Luna is pregnant with sixteen.”

The darker alicorn pouted, crossing her hooves over her chest. “Oh fi. I would have assumed we would at least be tied.”

Twilight rolled her eyes. “I don't really care how many of Shining Armor’s foals I’m pregnant with... buut it does feel nice to be so full.” A small blush crept across her features, a hoof slowly rubbing over the front of her massive belly.

“I’m just glad I stopped trying to keep up with Celestia.” Cadence remarked, throwing a wink to the other mare.

“I was worshipped as a fertility goddess after all.” Celestia remarked with a smirk.

Cadence was about to make fat joke when she noticed her husband still sitting there, his jaw hanging open. “Are you alright dear?”

“Eighty foals.” He slowly shook his head. “We have eighty foals.”

Luna chuckled. “Giving up already? Cus I was thinking I could take at least a dozen more.”

“More?” The stallion withered, nearly fainting before Cadence’s magic caught him at the last second.

“Hold on for a second dear. Twilight isn't done talking I think.” Cadence remarked.

Twilight nodded. “That's not all.” The mare continued her levipacing, tapping her chin all the while. “It seems as though all the fertility spells have molded together becoming a strange new type of magic.”

“Is that safe?” Celestia asked hesitantly, glancing down to her massive distended belly.

“For alicorns? Absolutely.” The purple alicorn shrugged. “I’m not sure about anyone else though.”

“So it's just a super fertility spell then?” Luna asked.

“Basicly.” Twilight began. “The pregnancy spells, coupled with all the other magic, and potions we have been using created a sort of feedback loop. I won't get into the details but basically this means that as of yesterday evening, every time Shining Armor finishes inside us, he is guaranteed to knock his partner up with another foal.” The purple pony scratched her head. “It gets stranger though, as this process also essentially resetts the pregnancy.”

“Resetts? What exactly does that mean?” Cadence’s features darkened and she glanced down to her stomach. “Is it safe for the foals?”

“Again, alicorn foals are different and they are actually in no danger all.” She smiled. “In fact they are growing to term very quickly before entering a sort of stasis. Which is why we haven't gone into labor despite carrying around at least half a dozen full term foals.”

Luna tapped her chin. “That does explain just how gigantic Celestia has gotten.” The smaller mare smirked, patting Celestia’s enormous stomach before her expression became serious once more. “Do you know what kind of affect this extended stay is having on the foal’s magic?”

Twilight nodded. “Nothing negative, that much is certain.”

“That's not what I would have guessed.” Cadence added.

Celestia nodded. “I have found that ponies that are delivered later than the estimated delivery date often have a slight advantage magicly.”

“Exactly.” Twilight agreed. “It seems that our alicorn physiology makes it possible to keep the foals inside us past the point that they normally would. My working theory is that our magic is making this possible so as to not endanger the other foals still gestating within our wombs.”

“That does make sense.” Cadence added.

“So what your saying is we could potentially be knocked up by a small horde of super alicorns?” Luna asked, innocently.

“Lulu! That's not very nice…” Celestia giggled. “Though I suppose your not wrong.”

“Well she is right, they would need to wear dampeners when they are young, as that amount of raw power would have some…” Twilight frowned. “Difficulties, that came with it.”

“Isn't this wonderful Shining?” Cadence blinked, looking down at her husband who was now pinned between her and Celestia’s belly. “Shining?”

“How many?” He whispered.

Twilight raised an eyebrow. “What did you say?”

“How many foals can you all get pregnant with?” He asked breathlessly.

The purple alicorn shrugged. “In theory an alicorn’s magical capability grows with demand, and this growth is seemingly without limit.”

“Does that mean what I think it means?” Celestia asked giddily.

“What are they talking about?” Luna asked, peeking around Celestia’s belly.

Cadence clapped her hooves together happily. “That means we could become pregnant an infinite number of times!”

“Infinite babies.” Shining Armor muttered, his gaze becoming distant as he stared off into space.

His wife rolled her eyes. “Not again.”

“Cadence is correct.” Twilight pointed out. “So long as Shining keeps inseminating us we could be pregnant forever with a near limitless number of foals which we wouldn't give birth to until he finally stops.”

“Wow.” Luna muttered, glancing from Celestia’s distended gut to her own. “That certainly is a lot to take in.”

“That it is.” Celestia remarked.

“It might be a little… strange, but I think this particular area needs additional study.” The purple pony smirked. “What do you girls think?”

“Now that I think about it, I could go for another twenty or so.” Luna remarked, staring fondly at Celestia’s massive belly, while rubbing her own comparatively smaller one.

“I could go for another thirty foals.” Cadence added, giggling, while rubbing her belly before turning to Celestia. “What about you?”

The alicorn tapped her chin thoughtfully. “I don't know. I had thought I was about at my limit but after Twilight mentioned it would be safe to keep going.” She smirked. “Another thirty foals would be fine by me, what do you think Lulu?”

Luna’s grin grew larger and she rested her head on Celestia’s stomach, rubbing her hooves over the larger mare’s stomach. “I think that would be lovely.” She whispered huskily.

Twilight blushed. “I wouldn't mind being as big as Shining wants.”

The four mares all turned to Shining Armor who looked at each of them in turn. “Are you girls sure about this?”

“It's not that big of a deal. I did figure out how to potentially dismiss the spell whenever we want.” Twilight smirked. “But I think we could all be a bit bigger. What about you girls?”

All three alicorn’s nodded their ascent, eying the male hungrily before Luna suddenly raised her hoof. “Dibs!”

The other three mares all groaned. “Oh come on that's not how this works!” Cadence whined.

“I don't know Cadey, I think Lulu has you on that one.” Celestia said with a giggle.

Twilight crossed her forehooves over her belly. “Oh come on, that's not fair. We should at least draw straws or something.”

Luna puffed out her chest, smirking. “Your just mad because your going to have to wait till last again.”

The purple alicorn’s eyes suddenly snapped open and she gasped. “Maybe not!”

Cadence raised an eyebrow. “What do you mean?”

Shining Armor blanched. “Please don't tell me you are going to try that double dick spell again.”

Twilight rolled her eyes. “No, but I did have a different idea…”

“What exactly are you implying Twilight?” Celestia asked pointedly, eyes narrowing.

“Well…” Twilight tapped her forehooves together awkwardly. “I may or may not have modified the time spell just a teensy weensy bit.”

Luna grimaced. “I thought we learned our lesson about time spells after last time.”

Twilight blanched. “N-no, not like that! I limited it this time with no possibility of accidental time loops or grandfather paradoxes.”

“Explain.” Celestia said sternly.

“Well… This spell can only go a few minutes back in time, two hours at the absolute most, which means we could get fucked all at the same time, by the same Shiny. From his perspective he would end up fucking all of us in turn but for us it would happen all at once.”

“That is the hottest thing I’ve ever heard.” Cadence muttered, mouth watering at the thought.

Luna nodded. “I concur.”

“I don't know Twilight, did you ever think of asking Shining if he was alright with this little plan?” Celestia asked sternly before smirking. “That does sound hot though.”

Twilight winced, looking up at her brother. “If that's alright with you Shining.”

“That does sound like fun, but-” Shining Armor started, before a sudden bang made him jump to his hooves.

There in the center of the room was three other Shining Armor’s in various states of erection. The furthest to the left grinned, licking his lips and eyeing up Twilight hungrily, while the rest eyed up the rest of the mares minus Luna.

Seeing this, the original Shining Armor rolled his eyes. “Let me guess, her dibs wins out huh?”

The other Shining’s all nod, with the leftmost one walking over to Twilight. “Just Fyi you cast this spell in about twenty minutes from now.”

“Then you cast an endurance spell thirty of your seconds after that.” The Shining next to him added.

“How do we manage to-” the original Shining started, before the rightmost one cut him off.

“The mares are all moved in a circle, allowing us to use the entire bed.” He rolled his eyes. “I’ve sat through this three times already, now let's go already, there isn't much time on this super endurance spell.”

The other ponies all laughed, before Twilight lit her horn and picked herself up off the ground and placed her massive, bulky body on the bed, with the rest of the mares following suit. Their sheer bulk made the bed groan, but the well constructed peice of furniture did not break, even as all four Shining Armor’s all joined them.

The original Shining mounted Luna, his hooves slipping snuggly on either side of her body as he draped himself over her well muscled back and sighed contently, his semi hard cock prodding against her hole. The mare smirked, grinding her hips back against him as she wormed her way into a more comfortable position.

The second Shining Armor eagerly hopped up onto Twilight, his already hard cock pressing against her hole and making the purple alicorn squeak in surprise. The stallion chuckled at the sound, his hooves going to her waist and gripping her massive flanks and squeezing tightly.

The third Shining Armor mounted Cadence, dipping down and planting a small kiss on the pink alicorn’s posterior. “You tease.” Cadence remarked with a giggle.

The third Shining chuckled. “You know it dear.”

The first Shining Armor eyed the other awkwardly. “Is this weird for anyone else?”

“Nope!” Yelled the fourth Shining Armor who eagerly leapt up onto Celestia’s ass.

The solar alicorn giggled. “Such an eager colt aren't you?”

The last Shining could hardly be seen behind the massive mare, with only his nose and horn visible over the top of her gargantuan ass. Celestia moaned, feeling the stallion eagerly line up his cock and squeeze her enormous flanks. “That's right, fuck me good and hard!” Celestia moaned.

The fourth Shining thrusted forward, nearly burying himself in the mare’s titanic flanks. “Sorry sweet cheeks, I had to wait through hearing you get fucked three times already.”

Celestia giggled. “Don't worry Shiny, I’m always ready for your cock.”

The fourth Shining Armor chuckled, before thrusting away, already burying himself in the mare’s enormous plot, his cock bottoming out nearly instantly.

The rest of the Shining Armor’s all rolled their eyes before the original leaned down and whispered. “Are you ready Luna?”

“I was born ready.” She whispered back, thrusting out her hips and forcing nearly a third of his cock into her pussy in a single swift movement.

Shining Armor smirked, noticing his doppelgangers all doing similar actions before thrusting forward. Following their lead, the original Shining Armor did just that, burying his cock into Luna’s generous pussy and easily bottoming out inside her in a single, deep thrust. He couldn't help but smirk as he heard the rest of his mares all moan aloud, their pussy’s no doubt getting fucked by his future selves at this very moment.

The idea was at first a strange one, and the sight of the other versions of himself standing there had been a little off putting, but now that he was getting right down to it, he had to admit it was kind of hot. Logically he knew those versions were all him, just him from a few minutes from now, which meant he was about to do everything they were currently doing. Thinking it like that made it easier whenever he caught a glimpse of his wife getting railed by someone who was both him and not him at the same time. He shrugged, noticing that the other stallions didn't seem bothered by this fact, and were eagerly fucking their mares with wild abandon.

Pushing these ideas to the side Shining Armor regripped Luna’s ass, squeezing her flanks tightly and drilling her pussy with every ounce of strength he had. Something Luna seemed to enjoy immensely as her moans joined a chorus of similar sounds that now filled the air. Shining focused solely on the mare before him, falling into the fast and brutal sex that he and Luna had come to know and love.

Despite the fact that she had easily put on a hundred pounds since they had first had sex, Luna still kept up the competitive spirit she had before, her alicorn physiology enabling her limbs to remain strong despite how much weight now hung on them. Even as her ass grew to titanic proportions, with her mate only barely able to wrap his hooves around both of them at the same time. The dark alicorn still had strength to spare, turning their love making into an almost violent fight for dominance in which both pony’s threw themself into the act, neither admitting out loud just how much they loved the feeling of the other pushing back just as enthusiastically.

It was a dance they had done a hundred times already yet it was one they never tired of. With each thrust Luna threw her hips back, her lip held tight in her teeth as she stifled a moan, not wanting to give Shining Armor the pleasure of hearing hers. Slowing her hips, the mare felt a sudden caress across her chin, drawing her attention up to the other mares.

Celestia was on her right, tongue hanging out of her mouth as she moaned loudly, long since having abandoned her princessly mask. Twilight was across from her, the purple pony biting her lip tightly as she rocked her hips back and forth, the Shining Armor behind her barely visible over her ass, with only his head able to crest the lip between her massive flanks. Cadence was to her left, wearing a knowing smirk, and a wide hungry look on her face, an expression that Luna knew well.

With a giggle, Luna leaned to her left, her lips meeting Cadence’s at the halfway mark, the kiss instantly deepening as the pink alicorn hungrily dove into Luna’s mouth. The dark alicorn had come to expect this by now, as the princess of love had an implacable desire to kiss when making love. Due to the fact that her belly was now so large as to make any such action impossible to perform with the stallion fucking her, she thus resorted to inevitably dragging one of her fellow mares into a deep and hungry kiss.

Shining Armor watched as Luna leaned over and kissed his wife, his hips surging as he saw the kiss deepen and Luna yield to Cadence’s dominant tongue. He wasn't sure why but something about watching Luna give in to her lust and simply let Cadence use her mouth as she saw fit was endlessly arousing and was the one thing he regretted being able to see when he got trapped between Cadence’s prodigious flanks. He made a note of installing a mirror on the ceiling, as this was not something he wanted to miss out on seeing after Luna’s ass grew too large to see over.

But for now, the stallion merely did his absolute best to keep up the brutal, hard hitting pace that he knew Luna loved while watching the dark alicorn slowly melt into the kiss she shared with his wife. It was something to behold, Shining Armor realized, and only his extensive experience serving as the mare’s lover could hkk
ave given him the experience necessary to spot when the change occured. Luna’s shoulders sagged, her neck turning a little more towards Cadence, her back relaxing slightly as she really got into it.

Shaking his head, the stallion forced his attention back down to her pussy, regripping her hulking flanks and really throwing his weight into every thrust.

The second Shining Armor smirked when he noticed his past self get absorbed into the make out session between the two mares. Even though he was here now, and the spell had evidently worked, he was still a little blown away by the sudden turn of events. Sure he knew from his past experience that it worked, and worked well, but to actually be here, in the past was a little mind blowing to the stallion. The nerdy part of him wondered what kind of time traveling rules there were, like if they were time cop rules, or timesplitters rules, or maybe even back to the future rules? Thankfully the horny side of him won out and he directed his attention down to the mare he was currently railing instead of pondering various movie time travel rules.

Cadence had always liked it rough, but not quite as rough as Luna, leaving the second Shining Armor to reign in a bit of his overeagerness that was still lingering from recently fucking the dark alicorn. His thrusts had to be measured, with each forward push of his hips having to meet the backward thrust of the pink alicorn. His wife loved reaching that state of harmony where their hips met with a wet smack but due to the fact that she was no longer able to use her legs to move herself, he had to move her hips for her.

Using his hooves, he gripped her waist and brought the mare’s hips back against his thrusts, slapping his massive testicles against her breasts and making her moan lewdly. He couldn't help but laugh at the slight bit of force that the mare could actually muster, valiant though the effort it was it did little to actually move his wife’s titanic weight one iota. Still, it was nice to know that she still put everything she had into the act and cared enough about his enjoyment to always keep trying.

Not like she really needed to though, between her massive pillowy thighs, enormous tits and flanks that he could drown in, he was enjoying himself about as much as a stallion was physically able to. No matter how many times he fucked that enormous ass of hers Shining still loved every second of intimacy with his wife. The sheer familiarity they had coupled with the fact that even with her tongue in Luna’s mouth she still managed to make the sexiest moans around which ensured that he loved every minute of it.

The stallion squeezed his eyes shut, drilling his wife’s pussy for everything he had, feeling the tight confines grip his cock in turn. Her inner muscles had grown incredibly powerful over the last few months, the mare having adjusted for her lack of maneuverability by becoming a master of milking his cock without even having to move. The way she gripped his cock tightly one second, before releasing him a second later as he pulled back from the thrust was something to behold. Shining Armor was perpetually amazed by the skill and love Cadence put into their love making, and with a massive grin on his face, the second Shining Armor threw himself back into the act, bound and determined to make her enjoy this just as much as he did.

The third Shining Armor was perhaps the most subdued out of his various time displaced selves. Twilight Sparkle had gotten over her desire to be ‘as good’ as the rest of Shining Armor’s mares awhile ago. Finally allowing herself to fall into a niche that she and Shining Armor enjoyed, that the other mares rarely seemed to relish as much as her. Compared to the frantic pace of the other time displaced copies, the third Shining Armor was moving at a snail’s pace.

Twilight had been new to the whole intercourse thing when they had begun to fuck and together the brother and sister pair had learned a lot about one another, including what they both liked and disliked, including how Twilight loved nothing more than a slow, sensual session that lasted for hours. Shining Armor wouldn't complain, especially as the only other mare that truly enjoyed this more slow pace was Celestia and even then only rarely. So it was that the third Shining was using the slower pace that Twilight loved, to take a breather of sorts during his marathon fuck session.

Though Shining Armor couldn't see his sister’s face over her massive ass, he knew she was enjoying herself. The subtle way her pussy spasmed, while her wings fluttered, were all easy clues but the way she whimpered in pleasure was the cherry on the top and the most obvious clue. Every time he thrusted forward she moaned, in a soft, half whispered way that never ceased to arouse him. There was an innocence in the way she moaned that the other mare’s lacked, and something about it made the rest of the room fade away as she became his only focus. Sure there was a part of him that wanted to be the fourth Shining, and to rail Celestia, but Twilight’s pussy was beyond compare and he wouldn't trade this moment for anything.

Using his magic, the stallion gripped his sister’s breasts, squeezing them tightly as he thrusted forward, making her moan a little louder. Her enormous ass shook, making Shining Armor’s cock twitch with need. He knew she needed this, from the way she tried her best to push back against him, to the desperate, needy moans it was obvious that Twilight was enjoying the fact that she could be knocked up with even more foals.

Shining Armor felt her pussy clamp down around his cock, her legs twitching as a powerful wave of pleasure washed through her.

It wouldn't be long now.

The fourth Shining Armor snorted like caged bull, his unbound lust finally having an output in the form of princess Celestia’s gargantuan ass and perfect pussy. The stallion hardly even minded the fact that his view was almost completely ass, because it was the most massive, perfect ass in equestria. The solar alicorn’s flanks were a sight to behold and no matter how hard he thrusted into his mare’s plush tush, it always had more give to it. Sure it was a little awkward because he had to physically stand on Celestia’s stomach due to her sheer size, and being unable to get away with utilizing good angles, or other tricks with the rest of his mares.

Celestia was different, her truly astronomical size making for even the act of intercourse to be a careful dance. He clung to her ass as best he could, utilizing his magic, and her naturally pillowy soft butt to keep himself from falling over backward and slipping out of her. Sure it was a little awkward at times, but Celestia had grown used to having her tits and stomach stood on while he fucked her, meaning she hardly even noticed as a slight shift of his weight made a surge of milk shoot from one of her breasts.

She was, after all, a tough mare, one who relished her gravid form and accepted all the complications that came with being so enormously pregnant.

Shining Armor grinned, feeling Celestia’s pussy begin to clamp down on his cock, the mare finally having recovered from the brutally fast pace that he had set from the first moment he had thrusted inside her. He couldn't help but grin to himself, feeling the mare squeeze his cock as her hips moved back as much as they could. The mare had long since been rendered completely and utterly immobile after all, and had begun taking lessons from Cadence in the art of milking cocks dry without even having to move.

She wasn't an expert quite yet, but that hardly mattered as she more than made up with it by having the most perfect ass around, and moaning like the absolute whore she was. The mare cried out suddenly, arching her back as much as possible while her wings shot out from her sides.

“I’m so close! Don't stop!” Celestia cried at the top of her lungs.

Every Shining Armor in the room grinned to themself, increasing their pace at the sound of Celestia’s pleasure filled voice.

Luna was next, moaning loudly and yelling out. “I’m close as well, fuck me full of your foals!”

Twilight whimpered, gripping her already foal filled belly tightly. “Yes, stuff me with your babies my love, I need to be bigger!”

Cadence giggled. “You know I’m close and you know what I want, give it to me lover boy.”

Every Shining Armor in the room grinned a little wider, snorting their affirmation as they threw their hips forward at the same exact moment. All four of them gripped a little tighter, fucked a little harder, pouring everything they had into drilling his mare’s into absolute submission.

Within seconds the four mares tensed, before crying out in unison. “I’m cumming!”

The four Shining Armor’s didn't have to say anything, as they knew exactly how this was going to end. Throwing their hips forward one last time, they buried their combined eight feet of cock into their mare’s tight bodies. His balls clapped against their breasts, before pulsing as they began to unload litre after litre of hot cum directly into his mare’s already full wombs. His face screwed into a tight mask of lust as he collectively let out a moan of pleasure, his balls finally emptying into his mares bodies.

He wasn't sure how, if it was some sort of time shenanigans or what, but Shining Armor felt his balls contract, squeezing out more seed then he had ever managed before in his entire life. Beneath him his mares stomach’s grew in real time, each Shining Armor feeling their mare grow with each pulse of their cock. Stomachs distended, wombs filled, and over a dozen more foals were conceived right then and there. All of which served to further increase the mare’s pleasure, making them reach new and untouched heights of pleasure.

Luna’s eyes rolled back into her head, her tongue hanging out of her mouth as her entire body quivered in pleasure. The way his body draped over hers, his massive, over two foot cock occupying so much of her body that it felt like she was little more than a baby factory for the domineering male, was amazing. The feeling of being so thoroughly violated, dominated and inseminated was beyond compare and the knowledge that she was being knocked up with potentially multiple foals at this very moment turned her on in a way that she had never experienced before in her long life.

Cadence was only slightly more subdued, a deep shuddering moan coursing through her body as her wings flapped uselessly at the sides of her body. She could feel every last inch of her husband’s cock as it twitched and pulsed inside her, depositing a seemingly endless stream of cum deep inside her. Though she relished his moans and sounds of his lust, she was utterly enraptured by the feeling of being impregnated so thoroughly in a single go and knew then and there that this was something she would crave for the rest of her immortal life.

Twilight Sparkle was completely overwhelmed by the feelings assaulting her mind. Through the months of near constant sex with her brother she had been shown new worlds of pleasure that she could have only dreamed of. Vistas of complete and utter joy that shattered her naive notions of what making love truly entailed. This experience was compounded after she began becoming intimate with the rest of Shining Armor’s little herd. But even with all that in mind, nothing compared to the way she was being fucked at this very moment. Like the other mares, she too had completely fallen in love with the feeling of being impregnated so thoroughly.

Celestia was not surprised by much, her list of lovers being long and storied through the centuries of loneliness spent waiting for Luna’s return. She had sex with just about every kind of pony of both genders over the years and yet even she was caught completely off guard by the amount of pleasure she felt in this moment. The moment of impregnation had always been one she relished above all others, but even compared to all the other times, there was something about this time that placed it above all others. In this instant she stopped being the princess of a country, stopped being even a pony at all. Right now she was little more then a broodmare, whose only purpose in life was to be fucked and filled with life and to give birth endlessly.

The four mares all shuddered in unison, their bodies quivering as they experienced the single greatest orgasm of their entire life. Each one falling utterly head over heels for the male currently pumping them full of semen and knocking them up with even more foals.

Their bodies grew in proportion, with each one being able to feel themselves rise a little higher as their stomach distended. Each mare was only barely aware of this change, so utterly blown away by the mind shattering orgasm that they hardly even noticed as their breasts and bellies became larger still.

By the time all four stallions were out of breath, and were laying half on their chosen mates over fourteen foals had just been conceived, and over seventy litres of cum had been shot inside them. The first Shining Armor was so taken aback by this that he looked around at his duplicates, noticing how the all flashed him a knowing grin.

“Oh I’m looking forward to this.” The first Shining Armor muttered.

His doppelgangers all chuckled before fading away, disappearing completely in a matter of seconds. Leaving behind his four exhausted, mares all lying their in mixed expressions of exhaustion.

“So, did you girls have fun?” He asked with a smirk.

“Oh you have no idea.” Cadence muttered, followed by a chorus of muttered affirmations.

Chuckling to himself, he lay on Luna’s back, giving the mare’s neck a soft kiss. “So, who's up for Donut Joe’s after this?”

And just like that the mood changed and all four mares exchanged a knowing look with Celestia giggling. “I think the guard can grab us some snacks. In the meantime I’m just about ready for round two.”

“That would be amazing!” Twilight exclaimed giddily. “That was the single best round of intercourse I’ve ever experienced.”

Luna rolled her eyes. “What Twilight said but less adorkable, more sexy.”

Cadence raised an eyebrow at her husband. “That is if you think your up to it.”

He smirked. “Oh I think I can keep going a little longer.”

Hours later, an exhausted, utterly empty, and now completely satiated Shining Armor lay with limbs sprawled in all directions atop a mound of belly. Below him his mares were all laid on their sides, bellies presented towards the center, where Shining Armor now lay.

For a moment he listened to their soft breathing, noting the content way his mares slumbered peacefully. A massive smile slowly crossed his face as he noted the way he was slowly rising, the mare’s stomachs growing fast enough that he could feel it.

He sighed, a deep, fulfilling sigh that could only come from a stallion that was so incredibly fulfilled that he was almost positive he had died and gone to some sort of heaven. As his eyes closed he couldn't help but laugh as he thought of how this had all started those many months ago.

In all his wildest imaginings he would have never thought that he would have been brought to this moment, all because of a single, tiny white lie.
