Growing in Love

“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.
