Fluttershy can't wait for her special somepony to get home... because today is the day she and him get BIG.

Fluttershy's special somepony is White Heart. He's a guard at Twilight's castle, but there's more to him than his job; his magic has the power to make things grow.

Fluttershy loves to have fun with White Heart's magic; he can give her breasts so big they hit the floor, or give himself a dick like a tree trunk. But today Fluttershy wants more. She wants to test the limits of White Heart's power. She wants them to grow together, until they can't grow anymore.

But what if his power doesn't have a limit? And what if, once he starts, he can't stop?

Chapter 1

“Is it true what they say?” asked Silver Wind, sidling up to me just as I lifted a cabbage from the vegetable cart and turned it over in my hands.

At first, I wasn’t certain she was talking to me. Anyone in Ponyville can tell you that I used to be an anxious wreck - though I’m sure they would use much kinder words - and I always used to assume that no one wanted to talk to me. Lately, I’ve been trying to kick that habit, but it still doesn’t come naturally. Self-improvement is a process!

“Is what true?” I said, tilting my head a bit as I turned to Silver Wind. “What does who say?” I wasn’t just playing innocent, by the way. I really didn’t know what she was talking about.

“About White Heart!” she said, giving me a sort of conspiratorial grin.

Just the sound of White Heart’s name made me feel like I was floating. Which is much better than flying, by the way. Flying is work. You have to keep flapping your wings or you’ll fall. Floating is peaceful and relaxing.

Of course, sometimes floating is just a metaphor for the way your special somepony makes you feel. And White Heart is very special to me. I couldn’t ask to have a better stallion in my life! But I wasn’t aware of anything ponies were saying about him.

“I know his special talent has to do with being a royal guard, but the word is, he’s got a talent that’s even more special. Something magical,” said Silver Wind, nudging me with her wing. “Just something I heard through the grapevine.”

I felt my cheeks getting hot. “You shouldn’t believe everything Grape Vine says,” I said, looking down at the cabbage I’d picked out. “She’s a bit of a gossip.”

“But she’s usually not wrong,” said Silver Wing. “And she heard from some old friends of his that his magic is very, very good at making things grow. All kinds of things. Pony parts, for example.”

“Oh, dear,” I muttered. “I really shouldn’t talk about that sort of thing. Not in front of the, uh…” I looked around. There were no foals around, not even any baby animals. “Not in front of the cabbages.”

Silver Wind laughed. “All right,” she said, “I wasn’t trying to make you uncomfortable, Flutters. Let me know if you’re ever in the mood for some girl talk.”

“All right,” I said, relieved that that conversation was over. I paid for the cabbage, doing my best to ignore the look of intrigue on the face of the stallion who took my bits. He’d overheard enough, apparently, that he wanted to know more. But I wasn’t telling.

On my way out of the farmer’s market, I passed the same intersection I always do. To my left was Friendship Castle. To my right… well, not immediately to my right, but eventually… was home. And as always, I was tempted to pay the castle a visit. Twilight would be there, and Spike, of course… and White Heart.

Of course it’s bad form to bother your special somepony at work, but I could have swung by without causing too much of a disruption. White Heart tells me that most days at the castle aren’t terribly busy. He takes his job very seriously, but this is still Ponyville. There’s no invaders to repel, and the population is small enough that Twilight can pretty much keep an open-door policy.

It’s my job I’m worried about. If I decide to pass the time with White Heart, I’ll probably end up flirting with him for hours, and my animals will go hungry. Besides, I know I’ll see him tonight, and that’s when we’ll be able to have some real fun. The kind we can’t have while he’s working.

One of the most important things to keep in mind, when you take care of as many animals as I do, is this:

Nature has been around since before you were born, and it’ll be around long after you’re gone. In more practical terms, that means that animals can take care of themselves sometimes. So if you feel like closing your cottage door and pouring yourself a cup of tea, just go ahead and do it. As the Element of Kindness, I give you permission to be kind to yourself.

As for me, I was doing that very thing when White Heart came home. I finished my cup as he came through the door, and I rose and crossed the room to embrace him.

I’m told I give very good hugs. For the longest time I wasn’t sure what ponies meant by that, but one day Rainbow Dash sat me down and explained it. “Your gazonkers!” she said, and I must have looked confused by her phrasing, because then she put her hands on my breasts and sort of jiggled them around for a second.

I do have very large breasts. I’m rather curvaceous all over, in fact, and for most of my life I thought of it more as an inconvenience than anything else. When you’re a shy mare trying to avoid attention from other ponies, having breasts bigger than your head seems more like a burden than an asset. Since I started making more friends, I’ve been more comfortable being seen… and on top of that, nothing makes a filly more comfortable with her body than the attentions of a loving stallion.

From the way White Heart leaned into the hug, pressing himself into the soft pillows on my chest, I could tell he loves my body just as much as he did yesterday and the day before that. My chest actually gets in the way a little - we have to lean way in if we want to kiss - but the feeling of his body up against mine makes it all worth it. My breasts and sensitive, the nipples doubly so, and the warmth and firmness of White Heart’s chest were sending gentle waves of soothing pleasure through my body.

And as I pulled him closer into the embrace, I felt a sensitive part of his body touching me. He’s quite a stallion, and his stallionhood is very impressive. I could feel his penis stiffening inside his pants, and I reached down a hand to stroke it through the fabric. Sometimes I can’t help myself when I’m alone with him…

He leaned forward, closing his eyes, and I met him halfway in a kiss. I couldn’t stop my hand from feeling up his penis, and he certainly didn’t mind. There’s something so satisfying about the feeling of a stallion’s member growing bigger in your hands, and White Heart provides more of that satisfaction that any other stallion I could imagine.

The truth is, I like it a lot when things get bigger. It never ceases to amaze me that there’s a part of a stallion’s body that gets bigger and thicker when you touch it… which was why I was so pleased when White Heart shared the secret of his magic with me. You see, Silver Wind was completely correct about White Heart - he has the power to make things very big. We’d played around with the power before, but today was the day I wanted to do something really special.

White Heart leaned back, breaking the kiss. “Wanna take this to the shower?” I nodded, and backed off. I’d been about to unzip his pants, so that I could get my hands on that big white beast he keeps in there… but if we were going to shower together, I’d be able to get my hands all over him soon enough.

“So how was your day?” I asked, as I followed him to the bathroom. “I almost decided to come visit you while I was shopping, but the animals needed me back here.”

“I wish you had,” he said. “Pretty uneventful as usual. Twilight seems to forget I’m around, most of the time. As long as I follow the daily checklist, I don’t have much else to do.”

“I don’t think she ever got used to the idea of hiring guards,” I said.

“Well, Ponyville might be small, but it’s sort of disaster-prone,” said White Heart. “One of these days she’ll be glad there’s someone guarding the castle.” Stopping in the bathroom, he reached down and pulled his shirt over his head, exposing the firm back muscles under his soft white fur. White Heart isn’t thick with muscle, but he does keep himself in excellent shape, and my mouth started to water when he began to strip.

He unbuckled his belt, and his pants dropped to the floor. White Heart’s butt is just perfect, and between his legs I could see his dangling balls, stuffed in the tight white sack that hung halfway to his knees. Not all mares have an appreciation for balls, and to be honest, I didn’t used to. But White Heart’s body charmed me from head to toe, the first time I saw him nude. I soon discovered how much fun it is to play with a set of balls that are so big and round.

White Heart turned around, and he frowned - a little playful disapproval - as he saw me still fully dressed. “Too busy gawking at me to take your shirt off?” he said. Then, smirking: “How about I help you bust out of it?”

His horn glowed, and his aura surrounded my breasts. For a moment it felt like warm hands were touching every inch of them - and then I felt a surge of growth as my breasts swelled. My hands shot to my boobs, and I rubbed my nipples slowly, feeling the increased sensitivity that came with the growth.

White Heart plays with me like this sometimes, and I love it. He never grows my boobs so much that they actually tear my clothes - when he teases me like this, he says he only grows them by about three percent, which certainly doesn’t seem like much. But the feeling is incredible. The skin is more sensitive, more receptive to touch afterwards - but the growth itself is the really fun part. I wish it wasn’t over so quickly…

White Heart pulled my shirt up, and I joined the effort, pulling the hem over my expanded breasts. It definitely helped to take two ponies doing it - my shirts are always tight even before White Heart makes my breasts grow. And as he helped me, I felt the tip of his penis brush against the underside of my breasts as it grew hard. I couldn’t see it - as with many things below my eyeline, my breasts got in the way. But the feeling of his soft tip against the skin of my boobs told me all I needed to know.

I pulled my skirt down and let it fall to the floor. “I’m ready,” I said, and I felt his dick begin to poke into the underside of my cleavage. If we stayed like this any longer, his growing erection would work its way between my boobs until the bulbous, silver-gray tip poked its way through the top. And if I let that happen, I would probably end up stroking his shaft with my breasts until he came. That’s one of my favorite things to do with White Heart, actually - as good as it is to have him inside me, it’s also fun to have him between my boobs - especially when he uses his magic to make us both big.

"Wanna get wet?" asked White Heart. He took my hands and stepped back, pulling me along with him towards the shower. The shower was a stall in the corner of the room, a very spacious one that we'd gotten installed shortly after White Heart moved in. He'd done a lot of the work himself, actually; he said it was important to him that the two of us have a shower we could comfortably share, and I must say it was a good idea. Even by myself, I take up a lot of space, and in a normal shower stall my breasts would be constantly pressing up against the sides. White Heart, of course, isn't curvy the way I am, but when he gets excited his penis gets very large... I can only imagine how frustrating it would be to maneuver a penis his size inside a normal shower stall.

At the edge of the shower, White Heart twisted the knob and tested the water. Once he was satisfied with the temperature, he stepped inside and pulled me along with him. My toes caught on the edge of the shower, and I slipped, stumbling into his arms. Fortunately, we were already holding onto each other, so he caught me easily enough - although he struggled to keep me on my feet. I don't usually think of myself as a heavy pony, but the truth is, between my breasts and my bottom, I do weigh a fair bit. White Heart stumbled back as he caught me - fortunately, he didn't slip on the shower's floor - and he ended up in the corner of the shower stall, pinned against the wall by my boobs.

"Oh, I'm sorry," I said instinctively.

White Heart waved off my apology, smiling. "Don't worry about it, Flutters," he said, lifting me back onto my feet. "I don't mind bumping into you, as long as you have this big soft cushions to bump into."

"Well, it's a good thing you made them bigger," I said.

"Want me to keep going?" he said, placing his hands on my nipples. "If I add a few feet to their circumference, you'll have cushions big enough to protect you from anything. Anyone bumps into you, you'll just bounce them into next week." His cock had calmed down briefly, but now it was coming back to full attention. I felt it brushing against my thighs as it rose up.

My imagination went to work on that image. We'd already played around with that kind of size - White Heart had given me breasts that hung past my knees, just so I could feel what it was like. It felt amazing - every jiggle of the soft flesh was like an orgasmic aftershock, rippling through my body. And when White Heart stuck his cock between them, stroking himself in and out - I came just from feeling him between my breasts.

"That would be nice," I said, leaning into White Heart's hands, letting his fingers sink into the surface of my tits.

"We could try it," said White Heart. "I'll give you breasts down to the floor, and you can live like that. Get Rarity to make you some bigger shirts. Maybe you could get back into modeling. No one else would have a body like yours, but you'd be impossible to ignore..."

"Mmm, maybe" I said. I reached a hand down and grabbed his cock, wrapping my fingers around it just below the tip. "But you have to do it too. Maybe give yourself... a five foot cock? A nice long dick dragging behind you when it's soft... and swinging around in front of you when it's hard."

White Heart leaned in, rolling his hips as I caressed his stiffening shaft. I maneuvered the growing member into the bottom of my cleavage - and this time, I was determined to take things further. "Flutters, I can't do that," he said, "I've got a job at the castle."

"I'm sure Twilight would order you a bigger set of armor," I said. His tip penetrated my cleavage, and I felt its length rising through the space between. "A big metal codpiece to hold in that nice big cock... you'd just have to be careful not to get hard at work... you'd have to try not to think about the busty, lusty mare waiting for you at home..."

"I couldn't," he whined. "It's so sensitive when it's big..."

"Well, we'll just have to do it here at home," I said. I looked down and say the tip of his cock emerging from between my breasts. Almost totally hard now. "Why don't you make yourself bigger right now?" I asked. "I'm going to clean off your cock, sweetie. Give me a big job to do." I grabbed a squeeze bottle of body wash, upturned it above my cleavage, and gave it a good squeeze. With a few jiggles of my tits, I turned the soapy goo into a ton of apricot-scented suds, slicking up my breasts.

"Okay," said White Heart, drawing in a breath. "I'll get big for you, Flutters." His horn glowed, and his dick grew thicker, pushing my tits apart. The head rose higher, pushing past my nose until it reached the level of my eyes. Now I couldn't see White Heart's face, not without tilting my neck; his fat cockhead completely obscured him."

"Oh, that is big," I said, shaking my soapy tits. "But now my titties look small by comparison. Maybe you could even things out?"

"Of course," said White Heart. His horn shone again, and I felt my tits get bigger. This time, White Heart wasn't messing around with three-percent increases - with a shudder of magical pleasure, they jumped in size, growing until they reached down to my knees. I moaned, spreading my legs to keep my balance.

"Was that too much?" asked White Heart, his voice unsteady. "It's... a little hard to control when... when I'm being groped..."

"No, that was perfect," I said. I let the water wash the soap off the tip of his cock, then leaned forward and kissed the bulbous head. "I like being your big girl." I wrapped my lips around the slit of his cock, kissing it deeply, tasting his pre with each flick of my tongue.

"Oh-" he gasped, and his cock jumped in size again, its tip rising over my head. "I don't know what's wrong with me today, I can't keep it under control..."

"It's okay," I said. "I want you big, White Heart." I leaned towards him, pinning him against the wall of the shower with my tits, lifting my slick, jiggling globes with my hands to stroke his shaft. I had him right where I wanted him now - even if he fought as hard as he could, he'd have a hard time escaping from my big yellow boobs. And he wasn't fighting back at all - I could tell he liked being where he was. "I want you big, and I want you inside me." I bent at the knee, mashing my boobs against him, pushing my tits together to squeeze his thick cock. "Do you want to be big inside me, White Heart?"

"Yes," said White Heart. "I want to be inside you, Fluttershy."

"Do you want to grow inside me, White Heart?" I asked. "I can't stop thinking about how it feels when your cock is deep inside me... when it's so big... I want you to get as big as you can. Show me your limit." I stepped back and lifted my breasts, exposing my pussy.

"I don't know if I have a limit," said White Heart. "I've never gotten much bigger than five feet."

"Is that so?" I said. "Not even when you were alone... and experimenting?" I grinned. "Get inside me, and let's finally test your limits."

"Okay," he said. He bent at the knee, legs apart, steadying himself as he grabbed his cock and angled it down. The tip of his cock was bigger than my head, much bigger than my pussy - but White Heart's magic did more than just make things big. He would fit inside me, no matter how big he got. I would stretch around his girth... and when he came inside me, I would swell up like a balloon, growing and bloating with his love.

The thought of White Heart's cum made my eyes shift downwards. He had a handsome set of balls, especially when they were extra big. His smooth white sack hung well past his knees now; when he enlarged his cock, he always made his nuts bigger too. And along with that came more wonderful cum. The shower was a great place to make a big sticky mess - it was fun to have White Heart's cum raining down over the two of us after a boobjob. But today I wanted all that inside me, a thick tide crashing into me, warming my body, filling me up.

In the extra-large shower, there was just enough room for White Heart to maneuver himself into me while we stood in opposite corners. The water washed the last of the soap from his shaft as he positioned his lip between my pussy lips, and he came closer, his nuts swinging as he stepped forward. I turned around, pointing my round yellow bottom at him, exposing my marehood. His fat cockhead slipped into me, and his magic tingled in my pussy lips as I stretched around him.

"Oh, White Heart," I groaned. My knees were quivering, but his cock supported my weight now that it was inside of me. "I need you deeper, please, go all the way in, give me all of your cock..."

White Heart stepped forward again, pushing another foot of his shaft into me from behind. I saw the shape of his cock bulging beneath my tummy - and more importantly, I felt it. My whole body widened as he entered me, making room for more of him.

"Fluttershy," he breathed, barely audible over the falling water, "you're so tight... so warm... I don't know if I can last too long..."

"It's okay, baby," I said. My hands were stroking my tits now, my palms circling the fat pink nipples, sending ripples of pleasure over the skin. "If you've gotta cum, just cum. But I'd love it if you could use your magic to make that last longer... after all, those big handsome balls don't have to run out of cum if they keep getting bigger, do they?"

"I guess not," laughed White Heart. Another foot and a half inside my pussy now, my body still stretching to take it all. I felt my ass growing, responding to his magic. It was a familiar feeling; "Okay, Flutters," he said, "I'll make sure I last a while..." He pushed himself further in, starting to move his hips back and forth - he didn't just want to be inside me, he wanted to fuck me. And I couldn't blame him; he was back there staring at my thick yellow bottom, watching me play with my tits. I'm a curvy girl, even before White Heart makes me bigger. And when my boobs and my butt start to grow... I don't blame White Heart if my body drives him a little bit wild.

"Fluttershy," groaned White Heart, "I'm close, I can't hold back... I'm gonna cum, I'm gonna cum, oh, I love you Fluttershy..."

"I love you too, White Heart," I gasped. "Please, if you're gonna cum... get bigger for me. Show me how big you can get. Make me big, fill me with that big fat cock... I want you to flood my pussy with cum, White Heart. I want us to grow until we can't grow any more."

"Okay!" grunted White Heart. "I'm gonna grow for you, Fluttershy... gonna hit my limit..." He was fully inside me now, his balls slapping against my thick, wet thighs with every thrust. I felt his cock grow thicker, spreading my pussy lips wider, His balls got heavier, slapping loudly against my thighs.

"Cum for me, White Heart," I moaned. I was pressed up against the side of the shower, my breasts flat against the slick tile. "Fill me, fill me, I want to be big..." White Heart came, shooting a thick, hot jet deep inside me, making my belly bloat. When he came, he shared his magic with me, shooting growth into my body. My breasts grew bigger, the soft flesh settling on my expanding belly. "Oh, that's good... oh, it's good, it's so good, oh White Heart... ahh... I love you!"

I can never hold out long once White Heart starts to come inside me. His climax isn't just a spurt of fluid, it's a powerful, thick rush inside my marehood. There's so much of it, so potent, an unceasing flow of love, pounding away inside me, touching even the parts of me that his long, thick cock can't reach. When I came, my pussy throbbed, grabbing hold of White Heart's shaft, milking it as it shot more and more cum.

"Oh yeah," said White Heart. He put his hands on my ass, steadying himself with big handfuls of the soft flesh. "You're so big and soft, Flutters... so big... we're gonna fill up the whole shower..."

"Keep coming," I moaned. "Keep coming in me. Make those big handsome balls bigger, so you never ever run out of cum..."

"I'll do it, I'll get bigger for you," grunted White Heart. "But I have to stop... before we break the shower..."

I didn't want him to stop. I didn't want him to ever stop coming. But he was making sense. He could just fill me until the two of us filled the shower with our big, beautiful bodies... and that would have to be enough. We were already getting close, though - my sloshing, cum-filled belly was already taking up about half the shower. And if I didn't miss my guess, White Heart's balls were probably almost as big as my boobs by now. Those big white nuts, growing every second and churning up more hot, thick cum for me...

“Okay,” gasped White Heart. “I’ve gotta stop, gotta stop growing…” He panted, and I could feel him growing thicker inside me, still pumping cum rhythmically into my pussy. He whimpered, his fingers quivering on my ass, digging into my cutie mark. “I… Flutters, I can’t stop,” he breathed. “I can’t make my magic stop, I can’t stop growing…”

My belly, still filling with cum, was totally round now - and it, along with my boobs, was taking up almost half the shower stall. I could feel my body pushing White Heart back as I expanded… and soon there was no space left to push him into. His body hit the far wall of the shower, and I could feel his nuts pressing against the underside of my belly as our bodies fought for space.

“I’m sorry,” he grunted, “We’re gonna break the shower. I can’t pull out, there’s no room…”

“It’s okay,” I said. I turned my head, meeting his eyes as best I could. His handsome face was turned upwards, little moans escaping his throat as he came. “I don’t want you to pull out,” I told him. “I want you inside me. Getting bigger. Coming. I want us both as big as we can get.”

“I want that too,” said White Heart. “If it’s okay… we can stay like this forever.” He grunted as his cock shot another thick, warm jet of cum inside me. The biggest yet… but the next one would be bigger, and the next one even bigger than that. “I love you, Fluttershy…”

“I love you too, White Heart,” I said. I felt another climax coming, rising like a wave. “Let’s… let’s grow together…”

By this point, the shower had no room left to hold us. I felt tile walls pressing in on all sides, growing tighter. It didn’t hurt, though; when White Heart’s magic made things bigger, it made them a lot tougher too. We might have been in trouble if the shower was made of solid stone, but tile didn’t stand a chance against our growing bodies.

And it broke apart, the tile cracking and falling away from us. Water sprayed from the busted plumbing, soaking the walls. The two of us tumbled away from the broken shower and found our footing in the center of the room. “I can’t pull out,” said White Heart. “I’m too big. My cock… too heavy... “

“Don’t worry,” I said. “When I said I wanted us to get bigger, I meant it. Stay inside me, White Heart… I don’t ever want this to stop…”

I could feel us growing faster now. White Heart’s cock was as thick as a tree trunk, stretching my pussy wider each second - and it must have been eight feet long, pumping more and more cum into me with each powerful throb. He thrust his hips, sliding about a foot of his length in and out of my slick pussy. Each time he thrust forward, I saw the outline of his tip distending the skin, bigger and bigger each time I saw it.

It didn’t take long for the two of us to reach the walls of the bathroom. My belly was soft and sloshing with cum, and it smushed against the wall as it expanded. My breasts hit the wall too - and they were so big that they also touched the ceiling. I shook my body, gasping as my nipples rubbed against the wall - they were so big that I couldn’t reach the tips, and it was nice to have something to rub them against. But I underestimated the strength that White Heart’s magic had given me - my breasts began to bring down the wall as I shook them.

Looking back, I saw White Heart pinned against the opposite wall. His big, handsome balls were impossible to ignore now - they were as big as my breasts, bigger than the rest of his whole body. And they brought down the wall behind him easily, smashing through the doorframe that led to the hallway. The impact kicked a big load of cum out of his sack, and my belly swelled with the massive inrush.

And that bloat brought down the wall in front of me, letting in the early evening sun. “Flutters,” moaned White Heart, “Sorry about the house…”

“You can stop apologizing, dear,” I said, turning to face him. “We don’t need the house anymore. We’re too big for it now… and I want to keep growing… we’ll never need a house if we keep growing forever…”

“I’m glad you think so,” said White Heart. “I don’t know if… if I’ll ever be able to stop. We might be like this forever… and… I’m glad. I want to grow with you, Fluttershy. I love you…”

He leaned forward, and our lips met in a kiss. Behind us, his balls continued demolishing our house, crushing it into splinters as his big white sack expanded. In front of us, my sloshing belly rolled over the grass, pushing aside trees each time cum flowed into it. I was bigger than I’d ever been, my body shaking with pleasure, climax radiating from my pussy with each thrust. White Heart, my love, was inside me, deeper than anyone else could ever be. And each thrust brought him deeper into me, his long, thick cock opening me wide and shooting like a geyser. The thought that this might go on forever - that my love and I would keep growing together - made me happier than I’d ever been.

Chapter 2

My head rising over the treetops, I saw Ponyville as it usually is in early evening. A few ponies made their way from here to there, or lounged about in the pleasantly mild weather. None of them had noticed me and White Heart yet, but it was only a matter of time.

“Oh dear,” I whispered, “Everyone’s going to see us…” I heard my own voice quavering, not just from nervousness but from my ongoing orgasm. I had already known that White Heart’s magic had a way of extending climaxes; when he enlarged his cock in the past, it would cum for minutes at a time. And when it was inside me, it shared that magic with my body, making my orgasm last just as long.

But this was something new. Endless growth, it seemed, meant an endless orgasm for both of us. White Heart’s body would never run out of cum, not as long as his balls kept getting bigger. And with his cock stretching my marehood, pumping an endless load into me, it looked like I was going to be coming for just as long.

It wasn’t easy to speak - or even to think - with climax shooting all along the wide curves of my swelling body. I could have let myself sink completely into the feeling, riding each crashing wave along with White Heart. But the presence of Ponyville - and hundreds of ponies who would soon notice my cum-bloated body - forced me to stay alert.

“There’s nothing we can do about it, Flutters,” said White Heart. “They’re going to see us. But it it makes you feel any better, you’ve never looked more beautiful.”

That did make me feel better. When White Heart tells me I’m beautiful, I can tell he means it. But even if I did look beautiful, that didn’t stop me from feeling exposed. Each time my belly swelled with a fresh gush of cum, my breasts grew along with them, keeping pace with the growth. And now that I was past thirty feet tall, my bare breasts were bigger than any pony. Big enough that just one of them would barely have fit inside the bathroom that we had broken open.

Carrying around big breasts had been embarrassing enough back when they’d been their usual size… and when I’d had a shirt to put over them. Now they were growing bigger every second, with nipples bigger than my head. Would ponies stare at my breasts? Would they touch them? The thought made my marehood pulse with heat, and the next rising wave of orgasm made me cry out as the sensation coursed through the sensitive skin of my expanding boobs.

My head remained in more or less the same spot as my body expanded; I was just rising upward as my belly lifted me higher. But as my belly grew upward, it also grew forward. My sloshing, blobby yellow tummy lurched forward across the path that led from my house to ponyville proper, flattening the trees on either side as it grew rounder and wider.

I could hear a series of dry cracking sounds from behind me, and it took me a moment to guess its source: it was White Heart’s balls, equal in size to my breasts, reaching the edge of the Everfree Forest. His quivering, endlessly full nuts were overtaking the wild woods, crushing the gnarled trees to splinters. I have mixed feelings about the Everfree; it’s home to many fascinating natural specimens, but they’re all rather unfriendly…

But when I heard my special somepony’s big white balls crushing the Everfree underneath, I didn’t have such mixed feelings. I was in awe of the power of his magic - and of his body. His balls were like boulders rolling over the fragile forest, and that display of power was incidental to their real purpose: to churn up an endless supply of warm, thick cum to fill me, to grow me bigger.

And Ponyville was starting to take notice of my size. Down the hill, among the outskirts of town, I could see ponies pointing fingers and starting to flee. I imagine they didn’t even know what they were looking at; the bright yellow of my fur would be familiar to them, but not when it was stretched across a belly some fifty feet tall. Even if they made out the shape of my enormous yellow breasts, wobbling with each wave of orgasm, I imagine most of them didn’t realize they were seeing little old Fluttershy. And even if they did, would they have guessed that they were seeing an act of love? Would they have guessed that it was White Heart’s huge, powerful balls and his big thick cock that were making me grow?

The surges of growth came in a relatively steady rhythm, but each one was bigger than the last. My belly, crawling towards Ponyville, overtook three feet of land in one surge… then five feet… then ten. And in no time at all, my big yellow tummy was pressing up against the nearest home in town. For a moment, I felt my soft, bloated belly deforming around the structure - but the weight of my body was too much for the little house, and it crumbled underneath as I expanded.

“Oh dear,” I said, “I hope everyone will be okay… we’re going to crush everything, White Heart. We’re going to outgrow the whole town…”

“There’s no stopping it now, Flutters,” said White Heart. “There’s nothing we can do but enjoy each other…” he moaned as his cock throbbed and shot its load inside of me. “Oh, Fluttershy, it feels so incredible to be big inside you… I can feel your pussy growing all around me…”

“Mmm, it’s wonderful to have you inside me,” I agreed. “I always loved to watch you grow… and feel you grow… and now I get to have that feeling forever. Whatever happens to the rest of the world… we have each other.”

Down at ground level, Ponyville seemed to be treating my encroaching belly like any other disaster: by calling on Twilight. She came charging out of her castle, ready to face the “threat” head on… but it looked like she hadn’t anticipated how much my growth was accelerating. First she was charging at me… then she was backing up… then sprinting away, casting the occasional look behind her. I called down to her, trying to keep my voice calm and steady - but I was hundreds of feet up now, with no hope of my voice reaching her. Just before my body overtook her, I saw her horn beginning to glow, and a warm tingle flowed through my body. It wasn’t sexual - it was the feeling of being enchanted.

I couldn’t tell what Twilight was trying to do with her magic. But whatever it was, she didn’t get a second chance at it; my body was expanding quicker than she could run, and it rolled over her, knocking her flat before the swelling yellow flesh covered her completely. I could feel her squirming under there, but the weight of my body didn’t seem to be hurting her… maybe that’s what the enchantment was doing? That was a nice thought. I was still crushing Ponyville’s buildings underneath my growing body, overtaking another building each time White Heart came inside me, but it would be nice if I wasn’t actually hurting any ponies.

There were only a few hundred yards of Ponyville left to conquer with my growing body, and I found myself excited by the idea. We weren't just growing, we were outgrowing everything around us. First the shower, then our house, and now Ponyville. Not to mention that White Heart’s balls were well on their way to crushing the whole Everfree forest.

I've never had what you might call an appetite for destruction, but I was starting to become addicted to the feeling. My body was becoming so powerful that nothing could contain it, and the feeling of a wall briefly resisting my growth, pushing back against my soft, squishy tummy until it finally crumbled… that feeling was almost orgasmic by itself.

So, eager to grow faster, I clenched the muscles of my marehood around White Heart’s shaft, trying to coax a bigger load from his enormous nuts. I could feel every inch of his cock inside me - and by this point, it stretched all the way from the site of our demolished house to the center of Ponyville. The tip of his dick was as wide as Applejack's barn - and I knew this for sure because when I cleaned my marebits down on his cock, he began to thrust. His hips were normal-sized, but they still had the power to move his immense cock in and out of me… and when he thrust all the way forward, I could see the outline of his thick, bulbous tip through the surface of my skin.

As I looked down at myself, admiring the size of my special somepony’s stallionhood, I saw the skin of my tummy distend a little further. Cum was flowing from his tip, pouring out of him, shooting like a geyser- and with my pussy closed tight around his cock, I could feel the strong, rumbling flow of thick warm cum through his quivering shaft.

His outpouring of cum spurred my own endless orgasm, triggering a series of throbbing pulses so intense that they drove all conscious thought from my mind. I couldn't think of Twilight, still squirming beneath me. I couldn't speculate about how much bigger we would get and what else would get crushed underneath our bodies. I just closed my eyes, curled my toes, and felt the climax ripple through my enormous body in rolling waves. Every square inch of my giant yellow tummy shivered with ecstasy - and as my body shook, my tits began to wobble with enough force to shake the ground beneath me. My swollen yellow boobs slapped against the top of my belly, making the soft, bloated flesh ripple and slosh as it overtook more and more of Ponyville.

“Oh…” groaned White Heart, wrapping his arms around my shoulders. “There’s so much, Fluttershy... I can’t stop…” He reached his hand forward and ran his fingers over the top of my right breast, stroking the soft yellow fur. “Flutters, you’re so big… you’re so beautiful like this… I just want to make you bigger…”

“Mmm, I can tell how much you want it,” I whispered. I felt a prickle under my belly, and I realized I had grown over Twilight’s castle. It was all sharp crystal edges, but it didn’t hurt; I suppose there wasn’t much in Equestria that could hurt me now.

“Fluttershy,” White Heart moaned, “Mnngh… oh, you’ve never been more gorgeous than you are now. Soon you’ll be a big, beautiful mountain… with all my love inside you… and more on the way…” He squeezed the flesh of my breast. “You’re the biggest, most beautiful mare in Equestria, Flutters… you’re bigger than Ponyville now… and Canterlot’s getting closer…”

“I can see it,” I groaned, feeling another wave of climax rise up inside me. “I can see it!” I couldn’t control the volume of my voice now; everything that came up from my lungs was an impassioned cry. “I’m going to grow until my big soft tits touch the tops of Canterlot Castle! And… until my belly rolls over the city… just like it rolled over Ponyville! Just keep coming, White Heart, please don’t ever stop coming… I need your love, I need it thick and hot in my pussy, I need it forever, forever and ever...”

“I won’t,” said White Heart. “I can’t! My cock is so big, I don’t think anyone could stop it… it feels like there’s a dam bursting inside me, over and over… and no matter how much I cum, my balls are always full… they’re so full, Fluttershy, they’re so full of cum, and I want to give it all to you. I’ll never stop giving you my cum, Fluttershy. I’ll make love to you forever… I can’t ever stop…”

White Heart’s cock pumped another load deep into my marehood. He was unloading entire lakes worth of cum at a time, swelling my belly and my tits, making my body grow and flow across the rolling hills between Ponyville and Canterlot.

“White Heart,” I said, finding myself in a period of calm between climaxes. “I’m so jealous of you… you can see me, but… since you’re behind me, I can’t see your strong, handsome body so well…” I turned my head, trying to see as much of my special somepony as I could. I could see his lovely face, and the top of his powerful chest - and behind him, stretching out just as far as my belly and my tits, was his big, handsome ballsack. It looked like two huge, rolling white hills, twitching with each intense pump of cum.

“Tell me,” I begged, “Tell me what those, big, full balls are feeling, White Heart. How much have they grown? Have they rolled over the whole Everfree yet?”

“I don’t think so,” said White Heart. “It’s a big forest… and… oooh… even though the trees feel so small now… I think there’s some more acres left to cover. And… I think my balls crushed a castle at some point... “

“The princesses’ old castle,” I said. “And… it just so happens their new castle is quite close now…” Far ahead of me, past the wide round hills of my boobs, I could see Canterlot Castle. Even though my body was growing closer to the royal city, my eyes were still above the former site of my house - and so I could barely see the city I was about to crush. I was growing quickly, but the ponies of the city must have noticed me at least a few minutes ago. Were they fleeing? Mounting a counterattack?

Whatever was going on in the city, I knew it wouldn’t stop me from growing. The love that White Heart and I were sharing was so good, so wonderful, so powerful, that I knew nothing could stop it. I knew that friendship and love were strong, but what White Heart and I had was beyond that. It was everything good about friendship, but more intimate, more physical. More fleshy and thick and hot and intense. No princess could stand in the way of this. Of us.

With a surge of cum, White Heart bloated my body until it bumped up against the base of Canterlot. The royal city is cantilevered off a tall hillside, higher up than most ponies realize - and it happened to be at just the right altitude that my belly could slip underneath it and my breasts could embrace it from either side. “Ohhh,” I moaned, “White Heart, I can feel Canterlot between my tits… it tickles…” As more cum flowed into me, I watched the city sink into my cleavage, disappearing into the deep yellow canyon. The tall towers of Canterlot Castle tickled the sensitive skin - and there may have been some ponies squirming and struggling as my breasts enveloped the city. By this point, I was too big to tell.

White Heart thrust inside me, moving his cock with enough force to make my whole body shake. My tits, still holding Canterlot between them, began to shake - and I felt the castle’s towers rumbling and collapsing between my breasts. “White Heart,” I groaned, “we’re breaking Canterlot, I can feel it… oh White Heart, we’re too big for this world… we’re going to outgrow everything, aren’t we?”

“We are,” said White Heart. “We’re growing faster… we’re going to grow past the sky… past the moon… I don’t know what’ll happen to us…”

“I trust you,” I groaned. “Your magic will keep us safe… and make us bigger, forever…” He came inside me again, and I felt Canterlot snap off from its base as my belly lifted it up. It was lost between my breasts, disappearing into my cleavage. Maybe it would stay there forever.

Each burst of cum was bigger than the last - and at this scale, that meant I was covering entire square miles at a time. Once my body grew over the mountains beside Canterlot, I couldn’t see anything in front of me but myself - just a horizon of soft yellow, wobbling gently with each pulse of orgasm. Beneath me, there were trees and rivers - and ponies - but the more I grew, the less I cared about Equestria. It was so small, and getting smaller by the second… but White Heart and I were big, and getting bigger. At this rate, it wouldn’t be long until my sloshing, cum-swollen belly was bigger than the whole world. My tits, bigger than the moon.

And White Heart would be right there with me, just as big, fucking me, filling me, with a cock that even now was miles long. I looked back, and past his moaning face and his golden hair I saw his ballsack, every bit as massive as my belly, dominating the landscape. There were mountains in that direction, I knew; I saw them out my kitchen window every morning. But now all I could see was my special somepony’s big fat balls, those wonderful white globes that would feed my pussy with oceans of cum.

White Heart opened his eyes and saw me staring back at his mountain-sized nuts. “They’re big, aren’t they,” he groaned, giving me a smile. “I know you liked stroking them… licking them… and now they’re bigger than ever, but they’re so far away…”

“It’s okay,” I said. “I like looking at them too… and I know that all the cum inside them is going right inside me… Oh White Heart, I’m so full but all I want is to be bigger…”

“I’m full too,” said White Heart. “No matter how much I cum, those big balls are just so achingly full… and I want to give it all to you…” he leaned forward, and our mouths met again. It was an awkward angle to be kissing at, but feeling his lips on mine and his tongue in my mouth was just as good as always. Better, in fact, with miles of thick, hard cock filling me up.

We went on kissing, moaning into each other’s mouths as we grew. The geographical features of Equestria felt smaller and smaller as my body expanded; at some point I felt dry earth under my belly, and then a few surges of growth later, I felt a cold wind making my nipples stiffen. That must have been the Crystal Empire - but it gave me nothing more than a brief shiver before it was completely underneath me.

And with spurts of cum that could have filled oceans, I grew past parts of the world that I’d never been to. I grew over lands I knew nothing about, I grew over oceans, I covered nameless islands with my expanding belly. And eventually, although my body was heavy with White Heart’s cum, I felt a strange feeling of weightlessness come over me.

I pulled back from the kiss. “White Heart,” I said, “I feel like I’m floating…”

“Me too,” said White Heart. “I think we’re getting so big now… the world can’t hold us down anymore…”

“I always feel like that when I’m with you.”

White Heart laughed. “I meant gravity. We’re so big that we’ll be like our own planets soon. We’ll float off… and leave Equestria behind…”

“As long as we’re together,” I said. “I’m going to miss Equestria… all my friends… all the animals… but being with you means more to me than all that. Besides,” I chuckled, “it’s not like I had much of a future taking care of animals, with a body this big…”

“They’ll be okay,” said White Heart. “Equestria will be okay without the two of us. We’re destined for bigger things, my love… and the more I fill you, the quicker we’ll lift off…”

He thrust his hips, going at me with all his strength. I usually had to beg him to fuck me this hard - on the nights when I was in the mood for it, that is - but now pure determination was driving his cock into me. And the force his thrust was multiplied ten thousand times over by the size of his cock. If it wasn’t inside me, his penis could have reached up from Equestria and knocked the moon out of its path. It could have flattened mountains. And all that mass was rock hard and hammering deep inside me - but my pussy could take all of it and still beg for more. After every thrust, my body wanted the same thing, only bigger and harder… and each time, he gave it to me.

As my special somepony railed me from behind, I felt us at last lifting off the planet, leaving Equestria behind. Saltwater dripped from the underside of my bloated belly, where I had dipped into the oceans - and then I wasn’t touching the world at all.

Of course, I still couldn’t see below me. There was too much me in the way; my breasts stretched out almost farther than I could see. I wanted one last look at the world I was leaving behind, but if I couldn’t have that… at least I had immeasurable volumes of cum pouring into me, and an orgasm that was neverending. And ahead of me was just space, a dark expanse speckled with beautiful white stars. I was used to thinking of this view as “the night sky”... but now it was my new world. I was a planetary body now, drifting along with my special somepony.

And just when I felt like I was getting accustomed to all these feelings - the size of my body, the sensation of floating, and the endless, throbbing release in my marehood… something changed. I barely know how to describe it, except to say that I felt like light was filling my body. Filling my belly, swelling my tits, flowing through my veins… and focusing at the crown of my head.

“White heart, something’s happening…” I groaned.

“I feel it too,” said White Heart. “My back is tingling… it’s like magic, but… different… more magical…”

“Like magic, but more magical” was actually a fairly good description of what the feeling was like. I felt the power centering on the crown of my head… then extending up and out, spiraling to a point.

“Fluttershy,” moaned White Heart, “I think I just grew wings…”

“Me too,” I said. “Uh, I mean... “ I put my hand to my forehead and almost poked my hand on a long horn. “I think… I also became an alicorn.”

“That’s wonderful, Flutters,” said White Heart. “I suppose a pony can only hold so much power inside her before she… ascends.”

“Do you suppose we’re bigger than the whole world now?” I asked.

“I don’t know,” said White Heart. “Let me make sure…” He thrust quickly, his balls wobbling in the weightless abyss, and a thick, powerful flow of cum burst inside me. I grew again, and while I still couldn’t see the world, I felt certain that I’d outgrown it. As we drifted, we slowly turned - and then I got my last look at the world. The blue ball looked so terribly small and fragile from here - partly due to how far away we’d drifted, and partly due to how big we’d become. I gave the world a little wave, and then we turned away again.

After that I started to lose track of time. There was no sun or moon to mark its passage, just the long, powerful thrusts of White Heart’s cock inside me. But I was still amazed by how quickly the two of us grew. I learned in school that the nearest planet was millions of miles away, but each splashing, crashing wave of cum made my body close more and more of the distance. In what felt like an hour, my left breast bumped against the little orange planet, bouncing it aside. Whatever its usual course through space, my body knocked it out of its path, maybe forever.

And in time, the stars didn’t seem so far apart. White Heart told me that a star bumped into his nutsack - but the way he said it suggested that it didn’t hurt. The heat of a star was no much for our magic, and our size - just like the cold of outer space didn’t bother us. And eventually we could see the shape of the galaxy all around us, swirling stars in a long spiraling arm. As we made love among the stars, our bodies disturbed countless stars, innumerable planetary systems. A single jiggle of my tits moved the stars out of alignment forever. The tensing of White Heart’s giant ballsack changed the shape of every constellation in the sky. Back in Equestria, ponies must have been looking up at us. One huge yellow shape, round and swollen with cum, and one white one, with a ballsack draped over the whole sky.

And we grew, alone together but perfectly content in each other’s company. For years we fucked, feeling each other in the most intimate way possible. White Heart loved me more longer and more deeply than anyone else could, as stars spun beneath us and galaxies dwindled in size until they were nothing more than pinpricks of light. He thrust inside me with enough force to make stars collapse, pounding at my marehood with a cock that was light-years long. Each load of cum could have submerged countless galaxies in thick, flowing white, but I held every drop inside myself. I grew so large that stars clung to my fur, their orbiting planets rebounding off my soft yellow breasts or my fat pink nipples.

I could barely even comprehend how big I’d gotten. The tips of my breasts were millions of light years away, but I felt everything - every star that bounced off my sensitive flesh, every galaxy that sunk into my swelling cleavage and was lost forever between my immense breasts. White Heart’s nuts, forever churning up an infinite load of thick, warm, wonderful cum, slapped against my belly with every thrust, smashing stars into stardust with the force of its impact.

Sometimes we spoke, and sometimes there were long silences where we simply felt each other. And sometimes we slept. Nothing could stop the endless orgasm we were sharing, but from time to time we drifted off, even as our bodies came and expanded in every direction. And one morning - although there were no mornings anymore, not when our bodies were bigger than any sun - White Heart woke me up with a kiss on the cheek.

“Fluttershy,” he said, giving me a gentle smile, “something happened while you were asleep. Do you see what’s out there?”

I turned my head and looked out ahead of me. There was an odd swirl of color all around us, a formless swirl that I hadn’t seen before. “What is it?” I asked.

“I think it’s the end of the universe,” said White Heart. I think we outgrew everything, Fluttershy. We filled up the whole universe, and we’re still growing. Every time we grow… we’re not just making ourselves bigger… we’re making the whole universe bigger.”

I laughed. “We’re finally bigger than anything,” I said. “I’m so glad we decided to test the limits of your magic, White Heart… and I’m even happier that it doesn’t have any limits. I love you, White Heart.”

“I love you too, Fluttershy,” said White Heart. He wrapped his arms around me and sunk his shaft deep into me - and when he came, my swelling body pushed the limits of the universe. “I’m so happy it’s you and me, growing like this… forever.”

Chapter 3

“Do you think it’s like this for Luna and Celestia?” I asked White Heart.

“I don’t know,” said White Heart. “I mean, there are rumors, but I never got the impression that they were actually… intimate.” He thrust his hips, slamming a few thousand light-years of cock into my pussy.

I laughed. “That’s not what I meant. I mean, it’s been millions of years, hasn’t it?”

“It has,” said White Heart. “I mean… there’s no night or day when you’re bigger than any sun…”

“But you can still tell, right?” I said. I leaned my head back, and White Heart nuzzled the back of my neck. “I can tell too… I was just wondering if this is what it’s like for other alicorns. Living this long, feeling time pass… and yet every moment feels entirely new.”

“I feel that way too,” said White Heart. “But I think that’s because I’m with you, Fluttershy. Whether or not we’re bigger than the cosmos, every day with you was always perfect.”

“And I bet it doesn’t hurt that you also have an endlessly growing cock, does it?” I said, “A cock that stretches from one end of the universe to another, shooting bigger and bigger loads of cum into my cosmic pussy?”

My words made his cock pulse with arousal, shooting a gush of cum big enough to extinguish a galaxy’s worth of stars deep into my marehood. White Heart was always coming, just like me, but there were still things I could do to make things even better for him.

“Nnngh,” grunted White Heart. “Yeah, it’s not bad. I’m glad we can be big together…”

At that moment, I saw something new. Cracks were beginning to form in the swirling color around us, exposing brilliant light on the other side. “White Heart,” I said, “We’re breaking through the edge of the universe… what do you think is going to happen?”

“We’ll keep growing,” said White Heart. “You and me, growing bigger and more powerful, making love forever. No matter where we are, that’s what’ll happen.”

The cracks in the edge of the universe grew bigger, like a pane of glass breaking in slow motion. And then it shattered, and the light from outside the universe flooded in, bathing the two of us in colors more brilliant and beautiful than any I’d ever seen. The whole rainbow was more vivid than it had ever been before - and I would have marveled at it with White Heart, except that something else started happening at the same time.

“Wh-White Heart…” I groaned, my whole body quaking, “We’re… we’re growing faster…”

“Oh… oh wow…” gasped White Heart. “Something happened… when we broke through the edge of the universe… my magic’s getting stronger… oh, oh, m-my cock… I’m cumming so hard, Flutters, I can’t…”

“Ooh, fill me,” I moaned. “I can feel it all… your cock is as long as the whole universe, and I can feel every inch in my pussy… shooting enough cum to fill all the darkness with hot, thick, white… make me big, fill my belly...”

I reached my hands out over my breasts and felt them expanding. I could never reach all the way around my tits, because my nipples were light years away and getting farther every second - but I could feel them growing faster than ever. My round belly was growing right along with them, swelling bigger as White Heart’s cock launched geysers of cum so big that they could sweep away galaxies. Those big, handsome balls of his were forever churning up more wonderful white cum for me - and we were growing so fast that just one of his balls was already as big as the universe we had just broken out of.

I could see other universes out there, dim spheres that gave off a bit of inner light. In time, the two of us would decide to call the space outside of universes “hyperspace.” But in the aftermath of outgrowing the universe, we were too overcome with growth to have much of a conversation. In the millions of years since we started growing, we’d adjusted to the feeling of constant orgasm. It never got less intense - quite the opposite! But we’d managed to get accustomed to it.

But now, outside of the universe, out in vivid swirl of hyperspace, we were growing faster and coming harder. In a little over a minute, White Heart’s cock was so big that one gush of cum could have drenched hundreds of the little universes floating all around us. And all that cock, all that indescribably long and thick and wonderful cock was inside me, thrusting and coming over and over again in my pussy.

And I was coming just as hard as him. My pussy pulsed with endless climax, each throb producing enough energy to bring entire universes into being. For the first billion years after we broke through into hyperspace, White Heart and I barely spoke in more than moans. The climax was simply too intense, even for us, and so we simply held onto each other, crying each others’ names, feeling each other grow.

A billion years is a long time for two ponies to barely speak, but when they share the kind of connection that White Heart and I have, no amount of time can come between them. And it didn’t hurt that we were fucking the entire time, experiencing an eternal shared orgasm.

Throughout all that time, the universes floating around us dwindled in size, smaller than pinpricks, smaller than atoms. But I could feel each one rebounding off my skin - some bumped gently against my swollen, sloshing belly, others against my sensitive pink nipples. The tickling sensation was slight, compared to the orgasm that was perpetually rolling through my colossal body, but it was a pleasant reminder of just how big I had become.

Sometime in the first million or so years, I had the idea to reach out into one of those universes with my magic. I was unaccustomed to using magic, having only become an alicorn after leaving the planet, but there was so much power in my immense body that I found it easy to hold onto a tiny little universe. It was remarkable how much of it I could feel, just by holding it in my aura - my magical senses could touch all the love and life inside of it.

And with so much power at my command, I wanted to do something for the tiny little creatures whose universe I was holding. All throughout that little universe, women’s bodies began to grow. Without warning, across every galaxy, their curves ballooned outward, breasts and butts swelling to tremendous sizes as they tingled with pleasure. For a brief moment, I was a goddess to that universe, sharing the blessing of size with the little people within… and then I released it, letting it drift back into the vibrant glow of hyperspace.

For hundreds of millions of years, I repeated the process with the universes that floated my way, blessing them with growth and pleasure. With only an infinitesimal fraction of my power, I sowed love and passion and magnificent growth through countless universes… all while White Heart’s godlike cock pumped bigger and bigger loads of cum into my divine marehood.

And at the end of that billion years, the two of us released long, heavy breaths, our faces flushed, and we found ourselves once again able to speak. The intensity of our eternal orgasm was still growing, but our minds and our mouths had finally caught up.

“Oh my goodness,” I said, turning my neck to look back at White Heart. “That was… really something, wasn’t it?”

White Heart gave me a smile. “You haven’t lost your knack for polite understatement, I see.”

“Well, I could hardly overstate it,” I said. “There simply aren’t words to describe how wonderful it feels to make love with bodies this big. And there’s no word that can describe how long and thick and fantastic your cock is, my love.”

“Then we can continue to let our bodies do the talking,” said White Heart. “Your pussy is very eloquent, in its own way.” He turned his eyes upwards, towards my long yellow horn. “By the way,” he said, “I saw you started to hold onto universes with your magic, so I started to try the same thing… and I found out I could share a little of our fun with the people living in them.”

“That’s what I’ve been doing too,” I said. “The two of us can be gods to those little people… giving their universes a little push, whenever they need a little more love… or bigger boobs…”

“That’s the Fluttershy I know,” said White Heart. “Always looking for ways to help.” He looked out at the bright glow of hyperspace. “Maybe someday we’ll outgrow this too,” he said, “And we’ll be big and powerful enough to share this blessing with everyone who exists, everywhere.”

“Of course we will,” I said. “We’ll outgrow everything. We’ll grow together, forever.” He leaned forward to kiss me, and I pressed my lips to his. It was a wonderful kiss, warm and passionate, good enough that I wanted it to last forever. Or at least for the next million years.
