Princess Cadence, and Shining Armor, had gotten used to deal with their daughter's magical surges. They had grown weaker as she had gotten older, making containing the surges just another part of raising a foal.

Though not all the surges can be contained, and a young mare that has just woken from a nightmare wants nothing more then a big strong mother to watch over her.

Quickly, Cadence finds herself outgrowing the castle, and Shining Armor is growing right along with her. So, they do the only logical thing, and sneak off into the mountains to enjoy each other until they stop growing.

Friendship is Magic: Big Mamma
By Winter Quill

Written for Klamnei

Cadence was right in the middle a working lunch with she felt a familiar surge of magic wash over her. “If you would please excuse me,” she told the city leaders, moments before the soft yellow glow encased her body and pulled her backwards out of the room.

She relaxed as she gilded backwards down the hallways of the crystal palace, around a tight corner, past a pair of startled guards, up the narrow servant stairs and into the royal apartments. Finally bringing her into Flurry Heart’s room.

That was where the spell broke, depositing right next to her daughter’s crib. She landed on all four hooves with practiced ease, then turned her attention to Flurry. The young alicorn was sitting up, sniffling as tears ran down her face. As soon as she saw Cadence she reached out to her with both forehoves and wings, babbling something that could have almost been ‘Mamma’.

“Did you have a bad dream?” Cadence asked, using her magic to pick Flurry up and bring her into her forelegs. Standing upright, she held her daughter against her chest and gently rocked her. “It’s okay, mommy is here and she will protect you from all those evil monsters.”

Flurry Heart babbled happily and pressed her face up against her mother’s pink fur, nuzzling it as she started to calm down. Just the presence of her mother was enough to help calm her down, her crying coming to a stop. It wasn’t often that she had a nightmare during naptime, but her mother’s touch was always enough to help calm her down and get her back to sleep.

Cadence gently stroked Flurry’s head with her hoof, reassuring the young mare as her eyes slowly drifted closed. “Don’t worry baby, mommy will always be here,” she whispered.

The foal cooed softly, relaxing against her mother as she sank back into her slumber.

Leaning over the edge of the crib, Cadence lowered Flurry Heart back down onto the bedding and brought over her whammy. Even sleeping she pulled it up against her chest, wrapping all four legs around the plush snail and tucking its head under her chin.

“Love you,” Cadence whispered, bending down to kiss her daughter on the forehead, right above her horn. Then, with a slight tug of her magic, she pulled the covers back over Flurry Heart. Her little baby was sleeping soundly again, her closed eyes already flicking as she returned to dream land.

She found herself standing over the crib for a few more minutes, just watching her daughter sleep, smiling at every little movement she made. Flurry had already grown so much in just the nine months, yet she still seemed so small and fragile.

Finally, Cadence pulled herself away from the side of the crib. She still had to return to lunch and deal with the leaders of the six city wards. Their constant whining was far more frustrating for her to deal with the her own filly. Carefully she tiptoed out of the bedroom, making sure her shoes didn’t make any sound on the crystal floor. She had just opened the door when Flurry Heart sneezed.

Cadence instantly tried to cast a contentment spell, but she wasn’t quick enough to stop her daughter’s magical surge. A lance of yellow magic blasted out from her horn towards the ceiling, but instead of impacting the crystal it made a sharp turn and shot straight towards Cadence. The magic hit her in the center of her chest and threw her back through the open door, to crash against the far wall of the hallway.

Her head spun from the magic as she slid down the wall. She could feel a complicated spell inside of it. There were layers of interlocking arrays moving as one, while other parts overlapped each other and even a few that were floating disconnected from the rest. There was an intent behind the spell, but she didn’t know what it was.

Climbing back onto her hooves, she took a moment to glance back into Flurry’s room. The foal was still sleeping happily, the tip of one wing in her mouth as she sucked on a feather.

Cadence smiled and shook her head, whatever spell that her daughter had attempted to cast, it didn’t seem to be having an effect on her. She could still feeling the magic moving around her, and if it didn’t fade by dinner time she would have Sunburst look into it, but for now she had more important things to do.

She took a moment to adjust her crown and hair, and then started down the hallway back towards the main staircase, holding her head high with each step she took. She had found that the best way to deal with the city leaders was to be confident and sure with them, and not let them see how frustrated they—

There was a loud crack as the tip of her horn embedded itself into the ceiling, the flecks of crystal raining down from the impact.

Cadence frozen in place, one of the small pieces of crystal having landed right on her nose. Even at her highest, even with her head lifted as high as she could, there was still a few inches between the tip of her horn and the ceiling. She had no idea how she could have hit her horn on anything in the hallway.

Above her the ceiling groaned, followed by soft cracking sounds as more small flecks of crystal fell around her head.

With a hard yank, she pulled her horn free of the crystal, then lowered her head as she continued walking. She only got a few more steps before she felt the trip of her horn scraping across the crystal again. That was quickly followed by her hips brushing against the wall.

Cadence turned her head to look back over her flank, shocked to see that she was almost filling the hallway. While it wasn’t wide enough for two ponies to pass (unless they really liked each other), there should have been more room than that!

She was growing bigger, and fast. She had to get out of the hallway before she found herself trapped inside of it. Lowering her head, she clenched her wings tightly to her back and rushed down the hallway, her flanks bouncing off both walls as she moved. She was heading to the center of the apartments, a large public room with high vaulted ceilings and a balcony that overlooked the city. It would the fastest way for her to get outside.

The hallway felt shorter then she had expected it to be, and she came to the end of it moments. She rushed through the doorway, feeling it scrape against her cutie marks as she did so. Her wings snapped open the moment she was out of the cramped space, slamming into the couch and shoving it back to the side.

Now that she was free of the hallway, Cadence tried to take stock. The spell Flurry Heart had cast was still dancing around her, the magical arrays pushing power down into her body, power that was making her grow with every passing moment. She quickly looked at the doors to the balcony, but they were already too small for her, there was no way she saw getting through them to get outside. She was already more than double her normal height, and the spell was growing with her, allowing it to siphon even more magic into her.

While it was a fascinating spell, and she knew both Twilight and Sunburst would want to understand how it worked, she just wanted it to stop. With a flash of her horn, she sent a spell flying to Shining Armor and Sunburst, letting them know she needed them, and that it was an emergency.

Her wings fluttered as she lay down in the center of the room, the walls creeping closer to her nose with every passing moment. While she waited for the two men in her life, she searched the spell for an off switch, or failing that a gap in the arrays she could break with her own magic. They were the traditional ways to end an unfamiliar spell, but she couldn’t find anything to take advantage of.

A shiver ran through Cadence’s body as her right primary feathers brushed against the wall, cause both her wings to snap closed against her back. At the same time she had to fight to urge to fan them out as wide as possible to try and clear space in the quickly shrinking room. She wasn’t sure what would break first, her wings or the walls, and she didn’t want to find out.

Finally she heard hoof steps coming up the large staircase from the floor below, and the two tall doors that stood as the official entrance to the apartments were flung open as Shining Armor barreled into the room, followed a moment later by Sunburst.

Shining had about half a second to realize that his way was being blocked by his wife’s flank, which wasn’t enough to prevent him from charging face first into her cutie mark. Sunburst had time to come to a stop moments before impact.

“Oh my,” was all Sunburst could say as he leaned his head back to look up at Cadence. Even laying on the floor, she was towering over the pair of them. Her barrel was at least a dozen feet tall, and growing even larger with every passing moment.

Shining Armor pushed himself off of her hip, shaking his head as he looked at a version of his wife’s cutie mark that was almost as big as he was. He found himself tracing the shape of it with his eyes, admiring how it stood out against the pink fur, and highlighted the curve of her powerful hips.

“How did this happen?” Sunburst asked, using his magic to grab Shining by the tail and pulled him away from his wife’s hip and closer to her head.

“Flurry Heart,” was all Cadence needed to say, but with her new size it came out at a volume only slightly below the Royal Canterlot Voice. Both of the stallions quickly covered their ears as her words reverberated off the crystal walls of the room.

Sunburst took a moment to adjust his glasses, his horn starting to shine as he examined the spell while Shining Armor started to walk the length of his growing wife, just taking her all in.

Cadence continued to grow, the ceiling getting closer to her head with each passing moment. It forced her to lower her chin down onto her hooves, though only a moment after that her nose pressed into the far wall. All the furnishings that had been the room had been shoved back by her growth, becoming pinned between her body and the walls. The room itself was starting to feel very cramped around her and she had to fight to keep her wings from flaring out in a panic.

“Can you stop this?” she asked. Even though she was whispering the words, they still sounded like a shout to the ponies next to her.

Sunburst reached up to stroke his goatee with his hoof, a move that always made him look even cuter then he naturally was. “I think so, but I would like more time to study the arrays before I try anything.”

“I don’t think we have the time,” Shining Armor said, standing by Cadence’s rump, watching as it started to press up against the other wall of the room. He had no scale to tell just how large she was now—other than huge! If he had to guess she was probably tall enough to look into the castle through the balcony while standing on her hooves.

With a nod, Sunburst took a step backwards, his horn growing brighter as he concentrated on the spell, the glow of his magic starting to shine in his eyes as well.

Shining trotted back around towards her head, wanting to be closer to her—or at least her face—when Sunburst cast the spell. At the moment there wasn’t any place in the room that wasn’t close to her.

“Okay, I think this should do it,” Sunburst said, his horn flashing bright yellow, a thread of magic reaching out from the tip to touch against the spells encircling Cadence. The other spell started glow in response, the shape of the flowing arrays starting to become visible against her pink fur.

Then, with a sound like a static shock, the stallion’s magic was thrown off the spells. It shot back down the thread of magic, right towards Sunburst.

Without thinking, Shining Armor threw himself against the smaller stallion, pushing him away and allowing the power to strike him instead. It impacted without any force, instead washing across him and making his fur stand on end. It took a few moments for the glow to fade from his body, giving him a feeling of pins and needles over his whole body.

“That didn’t work,” he stated.

“Oh, no. No, I wouldn’t say that,” Sunburst replied as he climbed back to his hooves, his cape sitting askew across his back, revealing his cutie mark to them both. “It allowed me to read some of the arrays. There is a inbuilt limit to the spell, so you will eventually stop growing, but I don’t know how big you will be.”

Shining nodded, turning his attention back to his wife. “You should teleport yourself to the outskirts of the city,” he suggested.

Cadence felt a blush burning in her ears as they sank down against the side of her head. She hadn’t thought about that at all, focusing on flying out of the room instead of using her magic.

“Although, there does seem to be an… unexpected side effect ,” Sunburst said, walking up to Shining Armor.

“And what was that?” Shining asked, turning his head to look at the other stallion. While he had always been taller than the wizard, I was only by a few inches. Now he found himself having to crane his head down to see Sunburst. He stared down at his friend for a few seconds, the size difference between them increasing as they watched.

He turned back to Cadence, his eyes scanning across her form. Running from the slightly upturned tip of her muzzle all the way back to her perfectly rounded flanks. His mind raced with the possibilities. “Maybe we should teleport farther away than just the outskirts,” he suggested.

Cadence nodded, though it was more of a tiny little motion of her head as there was no room for anything else. Her horn started to glow with magic, the blue aura wrapping around both herself and Shining Armor.

Sunburst smiled at the two of them. “Have fun!” he said, giving them a small wave with one hoof.

A moment later her magic grew even brighter, then with a flash of light the two ponies teleported away. The force of the spell almost knocking Sunburst off his hooves, as did the sudden gusting wind as the air rushed to the fill the void left by their departure. As the storm calmed he found himself looking at the space where the couple had been. The furniture in the room were flattened against the walls, and the crystal floor had actually buckled under her weight.

“Next time Shining, don’t push me out of the way,” he said with a slight shake of his head, then started trotting down the hallway to check on Flurry Heart.

* * *

Shining Armor had always enjoyed the feeling of Cadence’s magic when it was wrapped around his body. It was intimate in ways that a simple touch never could be. It washed over him, stroking along the edge of his ears, across his withers and all the way down to his dock. It might have been his imagination, but it always felt different than any other pony’s magic, like being wrapped in a warm blanket that he could snuggle right up against. It made him feel warm and safe even as she teleported them both across the Crystal Empire.

The teleport lasted only moments, the power gathering around the pair of ponies before winking them through the darkness between. The spell took them far north of the city and into the mountain range that marked the border of the Empire. All the way to a long valley that hung between two of the towering ranges of mount. Surrounded by tall mountains in every direction, it was nearly impossible for any pony to reach without using magic. It was here that Cadence and Shining Armor popped back into existence, half a mile above the valley floor.

Freed of the restrictive space of the castle, Cadence’s wings snapped out as wide as they could go. The magic in her feathers flared to hold her now massive weight, so much power that it made her primaries glow with an eerie bluish-white light. She flapped her wings, allowing herself to gracefully sink to the ground, landing gently on her hooves… only to have them sink through thick snow that covered every surface and into the ground itself.

Shining Armor, lacking wings of his own, was able to quickly catch himself in his own magic. While he wasn’t skilled enough to fly with his own horn, he was able to ride the dark pink magic all the way to the ground, touching down a few moments after his wife.

He took a moment to compose himself before turning to look up at Cadence. She towered over him, almost as tall as the crystal place itself, and she was still growing! Even her hoof was a third as tall as he was, and her knees towered above him. He found himself craning his head back to take her all, just looking at her gigantic form. From where he stood, about half way down the length of her body, he could watch as her chest expanded with each breath she took, or the way her feathers fanned out as she tucked her wings to her side, or even the thick strands of her tri color tail as they shifted and swayed against her hind legs.

He could also look up between her hind legs, her nipples were easily visible from that angle, each one big enough that he could use them as a pillow.

With a smile on his muzzle, Shining turning back towards her forehooves, only to discover that he was being watched. Cadence had lowered her head down to look at him from between her forelegs, her hair pooling out over the snow. There was a small flash of gold from inside the mass of hair; her crown, unaffected by the spell and now almost lost in her mane

“Like what you see?” she asked

Shining took a few steps towards her head, feeling his length starting to slide free from his sheath, the cold mountain air feeling rather nice on the bare flesh. “Always,” he said, approaching her upside down nose and giving it a boop with a hoof.

That made her laugh, then stuck her tongue out and licked him. Her tongue lifting him off his hooves for a moment, even as his face and chest were covered in her salvia. As kisses went it wasn’t the weirdest one they had shared.

Shining found himself laughing along with her as he dropped back to his hooves, shaking his head to get rid of the worst of it. “Now what to do about it?” he mused, glancing back up at her face, then over towards her forehooves. It was clear that he was growing, his head now closer to her knees then her hooves. At the same time she hadn’t stopped her own growth, all four hooves pushing outwards as her size increased, causing dirt and snow to pile up against them.

“I can think of a few things,” Cadence replied with a wink, then dropped onto her side in the snow. With how larger she was, it seemed to take ages for her to reach the ground, or maybe that was just because of how much Shining Armor enjoyed watching her move. Her whole body rolled to the side, her right hooves coming up off the ground as she tilted to the left. She fell gracefully, her mane trailing out behind her as she crashed into the ground with enough force to throw Shining back into the air.

She didn’t stop there, continuing to roll her body over until she was sprawled out on her back, her wings fanned out under her while her forelegs were tucked against her chest. Her hind legs were spread out wide on the snowy ground, framing her tail and leaving nothing to the imagination.

Shining Armor galloped around his wife, moving up to her hind legs. He paused for a moment to look at the underside of her hooves, nuzzling gently at the frog before slipping up between the legs, each one almost as tall as he was. He worked his way up towards her crotch, his hard shaft starting to slap against his belly with each step he took.

He could see her pussy ahead of him, the dark skin of her crotch standing out against the pink of her pelt. She was clearly excited as he was, the full lips of her sex were already damp and the nub of her clit was just visible peeking out from between the folds. Small dribbles of her arousal were starting to run down her crotch and collecting on the underside of her dock.

The size different was such that Shining could have easily push his whole head up inside of her cleft, but decided there were better ways to please his wife. Coming up to her pussy, he used his magic to stroke around her nether lips, teasing them with just the lightest of touches.

It was enough to cause Cadence to moan above him as her arousal grew thicker. He stepped carefully around her dock and finally took a long lick over the length of her cunt. The skin felt soft and supple against his tongue, and while the taste was stronger than ever before, it still had that little bit of sweetness that every single part of her seemed to have.

Shining licked his way up to where her clit was, the shining nub of flesh a brighter pink then even her fur. He teased his tongue across it before trying to wrap his mouth around it, only to discover that it was just a little too big to fit inside. Not that Cadence seemed to care, letting out a whimper and kicking one of her legs against the ground, causing it to shudder under his hooves.

He teased the huge nub of flesh one more time, trying to lick over every inch of it before pulling away. She was dripping heavily now, thick rivulets of her arousal dripping down from her pussy to soak his hooves. He started to nuzzle along her cleft, covering his muzzle in her juices while allowing the smell of it to fill his head.

Cadence brought one of her forehoofs down to start rubbing at her nipples. The large hoof hung over Shining Armor’s head, moving in circles above him. He reached out with his magic and rubbed gently against the frog while he went back to licking her pussy, teasing the tip of his snout inside while working his tongue in even deeper. Of course he could only reach so much as his head was half the size of her cunt.

“Oh, Shiny,” Cadence moaned, rocking her hips back against him.

Shining smiled, and continued licking her, his horn shine pulling away from her hooves in order to join him on her pussy, using it to tease her deeper then he could lick while he nipped gently at her nether lips. At the same time he lifted his hoof to start to rub at her clit, working it in slow circles as he pressed his tongue deeper, his growing size making it easier to pleasure his wife it sank into her silky depths.

He could feel Cadence’s legs starting to press against his flanks as his growing form filled more of the space between them. She squeezed them tight around him, holding him in place for a moment before relaxing slightly.

A moment later the familiar tingle of Cadence’s magic washed over him, rolling across his back and through his tail before reaching under his belly to cup his balls. He couldn’t help but shiver at the intimate touch, loving how the slight tingling of the magic teased the skin of his sack. It only lasted for a few moments before the magic pulled away from his balls, but only to wrap around his cock.

Shining Armor frozen at the touch, the magic dancing along the length of his shaft until it was rubbing over the head. As the field started to stroke his length, a second field squeezed around the base of his cock, right up against his sheath, making him moan happily into his wife’s pussy.

Cadence kept teasing his shaft, the grip of her magic alternating between firm and soft, sometimes one of the magic fields reached back to play with his balls and other times it would concentrate on teasing the head of his shaft. A steady dribble of precum was leaking from the tip, falling right though the magic to pool on his wife’s tail.

For his part, he stayed focused on her cleft, running his snout along her soaked nether lips, while working his tongue deeper inside. The fur on his face was mated with her juices, the intoxicating scent filling his head with every breath he took. He worked his tongue and magic deeper inside of her, gently brushing the lightest touch of his aura across the soft folds of her depths, causing her leg to kick at the ground, dirt and rocks up into the air to rain down over his back.

Her magic squeezed at his shaft, stroking him faster as she let out a high pitched whimpered, the sound echoing across the mountains around them. Cadence squirmed and kicked her hoof again, starting to gasp out as her magic squeezed him tighter and tighter as she rose to the brink of her climax.

Shining Armor stopped his ministrations, leaving her teetering on the edge. He gave her a few moments to stew before he leaned forward and ran his tongue along the full length of her pussy, then nipped his teeth against her clit.

His wife let out a cry, her back arching against the ground as she was pushed over the edge and right into an orgasm. Her whole body rocked, her wings fanning out and slamming against the ground, throwing snow up into the air as her hind hooves dug into the earth. Her pussy clenched tightly before opening again with a spray of her juices, soaking almost every inch of his upper body.

Her orgasm only lasted a few wonderful moments before it finally came to an end, Cadence’s body falling limp as she crashed back down. “Oh… that was nice,” she said.

Shining let out a chuckle as rose up onto all fours, looking over the curve of Cadence’s belly up to her head. Her eyes her half closed and she had wide smile on her lips, one leg resting across the top of her head. There was a thin layer of froth along her neck and barrel, soaking into her fur.

He guessed he was a bit more than half her size, but while he was catching up to her she hadn’t stopped growing. By now, she almost filled the whole valley they were in. The back of her head was propped up against one of the mountains, her horn reaching above the top of the ice covered peak. Her wings were stretched out as wide as they could go, rising up against the taller peaks on either side, the primaries lacing between them.

She must have been two miles long from horn to dock.

“Sun and Moon, you look amazing,” Shining Armor said, his cock slapping against his belly.

Cadence lifted her leg away from her head and gave him a smile. “So do you, even more so when you’re covered in my cum.”

He smirked and flicked his tongue up to lick over his nose, getting another taste of her juices.

The gigantic mare looked down over her husband, a smile started to play over her face. “You know what I want now?” she asked, her wings pulling back to her sides. The force of the feathers against the mountains caused a number of avalanches, sending snow and ice tumbling down into the valley below. For the two royals it was hardly more noticeable than falling sand.

“What do you want now?” he asked, his ears perking up.

“You,” Cadence replied before lifting herself up enough that she could roll over in place. The force of her dropping onto her belly caused the whole mountain range to shake as the earth below her compressed a few feet, conforming to the shape of her wonderful body. With her rear now pointed at Shining Armor, she flagged her tail high, and winked at him.

Never one to turn down such an invitation, he reared up and dropped his hooves onto the soft cheeks of her ass. Walking forward, he used his magic to guide his shaft into her eager twat. At his current size there was hardly any resistance, allowing him to sink his whole length inside of her.

Cadence let out a moan, her cunt clenching around him, the soft flesh growing tight for a moment before she relaxed. “Oh…. that’s it Shiny, just like that. Now, fuck me!”

Shining wasn’t going to ignore an order like that. With a smirk on his face he started thrusting. Thrusting and growing. It seemed like each time he hilted himself into her, he went a little bit deeper and the passage became a little bit tighter. It was an amazing feeling, helped by the way she would work her skilled pussy around him.

He started pawing his hooves against her cutie marks, pressing firmly against them each time he thrust forward, bring a gasp from his wife. They were always so sensitive when she was horny, and he knew just the right place to touch them to get her even hotter.

Each wet slap of his crotch to hers sent another wave of growth through them both, the valley getting smaller by the moment, as the mountains closed in on the two ponies. This time though, Shining Armor was growing much faster, his body rushing to catch up with his wife’s.

The best part of it was, the bigger he got the tighter Cadence’s became, which made fucking her feel ten times better. He couldn’t help but let out a low moan, reaching down to bite onto her tail, tugging on the pink, purple and yellow strands as he shifted his position to better plow her. He was only a third her size now, and it was getting awkward to fuck her while she was laying down. “Stand up, hon,” he said, gasping out the words.

Cadence moaned in response as she started to rise onto all fours. She took it slowly, allowing him to keep up the pace of his thrusts even as she rose up to her full height. The two ponies both stood above the mountains around them, the once towering peaks now only reaching the height of their flanks, and quickly growing smaller by the moment.

Then suddenly, Shining thrust himself into Cadence only to discover that she fit perfectly around his cock. The warm walls of her pussy pulling tightly around his shaft, sucking eagerly against the flesh as he pulled back, trying to keep him inside. It also allowed him to lean his head forward and nip gently at his wife’s ears, which caused her to lean her head back, exposing the underside of her neck to him.

Shining wrapped his head around her neck, nuzzling against it as he plowed her. Their growth was now in sync with each other, the pair towering ever higher with each he sank his cock into his wife. He wrapped his forelegs around her barrel, holding her tight as they fucked. His thrusts started to grow harder, slamming into her, rocking both their bodies as one.

Cadence let out a low moan, her horn starting to glow bright as her magic stroked all over Shining’s body, teasing and touching him everywhere at once. Brushing across his chest, over the base of his horn, along his cutie mark, and even under his tail.

It was enough to finally push him over the edge, his balls pulling tight up against his crotch as the head of his shaft flared inside of Cadence. Thrusting hard, he sank inside of her as deep as it would go. He wrapped his forelegs around his wife, pulling them tightly together as he came. His cock bucked inside of her as his cum blasted deep into of her fertile womb.

Throwing her head back, Cadence let out a cry of joy as her body was rocked by another orgasm, her pussy spasming around Shining’s cock, milking out his seed while at the same time her own juices gushed out around his shaft, the tight fit causing it to spray out over his balls.

The couple rode out their shared climax, one last surge of growth rushing through their bodies, pushing them even higher as they outgrew the valley, the mountains sinking down below them.

As their passion finally waned, Shining slumped against Cadence’s back. A moment later her legs gave out and she collapsed to the ground, falling across the mountains. The million year old peaks were easily crushed under the titanic mare, the whole of the frozen north shaking under the impact.

They panted together, breathing in time as they nuzzled each other, noses touching for a few moments as they composed themselves. “We have to do this again,” Shining finally said.

“Definitely,” Cadence replied as she looked out over the whole of the mountain range, able to see all the way from the Crystal Empire to Yakyakistan and even further beyond. They had to be twenty miles tall, but sadly were no longer growing. “Though maybe next time we can get even bigger?”
