Flurry Heart's magic acts up again, and this time it makes Cadance's boobs grow uncontrollably.

Cadance discovers that being a mother—and the mother of an alicorn to boot—means doing things she thought she'd never do. Like taking care of a tiny, noisy, stinky person who demands her attention at the worst possible time. Or saving her kingdom from a wintery apocalypse.

Or dealing with the consequences of raw baby magic, blasted right into her groin.

[Fetish story. Contains crotchboobs, breast expansion, and crotchboobs expanding far beyond the limits of good taste. "Sex" tag is for a pony getting turned on by her aforementioned crotchboobs expanding.]

Mother of the Year

Parenthood was strange, Princess Cadance reflected. Even though her daughter had driven her nearly mad with worry—and cost her and Shining Armor countless hours of sleep—and honestly, she couldn’t remember anymore the last time the two of them had sex—and, oh yeah, who could forget the time her little angel threw a temper tantrum that shattered the Crystal Heart into a million shards?—she still couldn’t help but love that foal.

Maybe it was Flurry Heart’s beautiful smile. Maybe it was the boundless potential that the foal embodied. Maybe it was just hormones in Cadance’s brain—an evolutionary adaptation to ensure ponykind wouldn’t go extinct via infanticide. But whatever the cause, every time Cadance looked at her daughter, her heart filled with enough motherly affection to send the Crystal Heart into overdrive. It was one thing to know about this love—Cadance was, after all, the Alicorn of Love—but another thing entirely to be filled with it, filled to bursting.

Flurry Heart was nursing right now. As Cadance gazed down at her, she almost couldn’t believe that this beautiful alicorn infant suckling on her teat was the same child who almost reduced the entire Crystal Empire to a frozen wasteland.

“Yes, drink up, dear,” Cadance cooed. “You need lots of milk to grow strong and healthy.”

Cadance and Flurry Heart were alone in the nursery which was, thankfully, in order—quite a rare occasion these days. Flurry’s dozens of toys were all stowed in the toybox, and all evidence of her last potty accident had been thoroughly cleaned up. Both of Flurry’s cribs rested next to the wall—one of traditional Apple family design, and another utterly ancient, crystal pony crib, wrought from the living stone of the palace itself. Cadance lay on the sole rug in the center of the room, on her side so her daughter could easily reach her teats. And Flurry was very focused on them, apparently intent on milking her mother dry.

At long last, Flurry stepped away from her mother. She smacked her lips, and a little milk dribbled down her adorable chin. “Gah gabba dah,” she gibbered.

“Aw, is my little girl full?” Cadance extended one hoof to wipe off Flurry’s chin.

The foal laughed and smiled—a smile so beautiful it melted her mother’s heart. In fact, that smile probably could have melted a glacier the size of the entire city. And then she closed her eyes and reared back to sneeze. “Aah... Aah...”

Cadance had just enough time for a chilling thought to run through her head: Wait a second. How long has it been since I re-cast Fledgling’s Forbearance?

“CHOO!”

A foal’s magic is formless, undirected, full of limitless creative potential. And when Flurry Heart sneezed, a massive beam of that potential fired from her horn, straight into her mother’s groin.

“Oh!” Cadance exclaimed. Her daughter’s magic blast didn’t hurt at all, but it certainly was... surprising? Bracing? Yes, bracing was a good way to describe it. For the briefest instant, a shocking coldness covered her teats, haunches, and loins—but that quickly gave way to a more pleasantly cool sensation, with an odd sort of tingling added.

Cadance rose to her hooves—then paused, her eyes wide. She had jiggled as she stood up, in a part of her that had never jiggled before. She lowered her neck to examine her own underside, and boggled at what she saw. Her teats were larger. Before, they had been entirely average-sized, slightly perky mounds; now they were much rounder and nearly the size of tennis balls. And—Cadance gasped as she realized—they were still visibly growing, and showed no signs of stopping.

With a weary smile, Cadance turned away from her swelling mammaries and looked at her daughter. “Flurry, you rascal. Look what you did to Mommy!” She shook her hips enough to set her teats—now larger than baseballs—wobbling. “Ohhh...” Cadance shook a little more. The sensation of her teats brushing against each other, against the insides of her hind legs, was much nicer than she had anticipated.

Flurry’s attention was elsewhere, however. “Bah bah guh!” she exclaimed, then galloped right out the door.

“Oh, no you don’t!” Cadance cried as she set off in pursuit. With her much longer stride, she should have caught up with Flurry quickly, but something was throwing off her pace. Or rather, two somethings. Her crotchboobs were large enough that they shook with every step—painfully so, if she tried to gallop. So Cadance settled for a canter instead, which was still enough to set her mammaries a-jiggling in a most distracting manner. Not only did their smooth, soft skin brush against her belly and legs as they sloshed back and forth, but the more they grew, the more sensitive they became.

That feels... she thought. No! Mustn’t get distracted. I need to catch Flurry.

Up ahead, Flurry Heart teleported away, giggling as she disappeared.

Of course, Cadance thought.

Flurry was powerful, but her technique was sloppy (after all, she was just a baby), so Cadance had no trouble picking up her residual magic trail, then teleporting after her. She reappeared in the Great Column Chamber: a cavernous room with a three-story-high ceiling supported by rows upon rows of columns—like a geometric, crystalline forest. (As far as anypony could tell, it served no purpose except to impress important guests, or to ditch unwanted guests.) Cadance couldn’t see Flurry, and the room’s strange acoustics would make it impossible to follow the baby’s burbles and giggles. But Cadance could magically sense her daughter’s presence quite clearly, so she set off in that direction, dodging and weaving around columns as quickly as she could.

Cadance tried to focus solely on the task at hoof, but her teats were still growing, and thus growing harder to ignore. They were filling the space between her haunches—not only wobbling, but rubbing against each other with every movement of her hind legs. Her mammaries had stopped feeling cool some time ago; now, they grew pleasantly warm as they jostled and squeezed together.

There was no concern about this change being permanent. Cadance knew enough about Flurry’s wild magic that she had every certainty she could undo it. But unraveling this particular effect would take time—and in that time, there was no telling what mischief Flurry might get up to. Clearly, Cadance had to rein in the baby first, before doing anything to stop her own inflating crotchboobs. So, no matter how big and bouncy they got—how sensitive they became—how good it felt every time they wobbled—well, she would just have to grin and bear it.

Oh, the sacrifices I make for my family, Cadance thought wryly. Her teats were larger than cantaloupes now, and approaching the size of soccer balls—albeit, somewhat flattened ones, given how her legs squeezed them.

“Deeeeeebah!” Flurry Heart exclaimed, her voice coming from somewhere to Cadance’s right. But when the foal shot off another blast of magic, the flash came from the left, so that was the direction Cadance turned. As she rounded a crystal column, she noticed her own reflection in its surface, and couldn’t help but chuckle at what a ridiculous figure she cut. She looked like a prostitute from... how long ago was the last time huge teats were considered the ideal of feminine beauty, again? Three centuries? Her milk jugs would have fit right in, back then. Speaking of fitting in, they distinctly didn’t want to fit between Cadance’s hind legs any more—and they pressed harder against the inside of her haunches with every passing minute.

Cadance turned to the right, as she sensed Flurry changing direction again. Closer and closer she drew to her wayward foal.

After passing four more columns, she noticed her reflection again. Her teats were now so large that even those weird ponies of old would have considered them excessive. She had unconsciously spread her hind legs to give her crotchboobs more room—but even so, her smooth, soft mammary flesh squished around her haunches, both in front and behind. Her nipples hung well below her stifles. The teats were hefty as well, and growing heavier by the second, but they weren’t too much for Cadance’s alicorn strength. For now.

“Gooboo...” Flurry Heart said, and Cadance turned again towards her.

It occurred to Princess Cadance that she hadn’t seen or heard from any of the palace staff or guards since this strange incident began. Part of her brain hoped that this string of good luck would continue, that she could catch Flurry without anypony seeing her current condition. But another part of her brain hoped she would be discovered. Let them all see me, she thought. Let those crystal ponies wonder just how freaky their Princess of Love really is. Naturally, this was the part of her brain that was receiving near-constant pleasure signals from her mammaries. Every step she took—every jiggle or wobble, every time her teats squished together—was another wave of pleasure, slightly larger than the one before it. Wobble, squish, wobble, squish, wobble, squish. Oh, yeah, that feels good, she thought, biting her lower lip. Wobble, squish, wobble, squish—

Distracted thus, Princess Cadance—with all the grace befitting the Alicorn of Love—walked face-first into a column. Dazed, she flopped back and landed on her rump. She would have sprawled on her belly, but her mammoth mammaries cushioned her torso, propping her semi-upright. When she regained her senses, Cadance simply stared down. Her milk jugs were now indisputably milk barrels; they were almost large enough to fit a teenaged mare inside. And even though she wasn’t moving, those teats kept sloshing and churning as they grew larger and larger.

Cadance had the sudden, almost overwhelming urge to... well, play with them. After all, for the past few minutes she had been groping herself, more or less, with her hind legs every time she took a step. So why not let her forelegs get in on the fun? She could already imagine how it would feel—her legs sinking into that soft flesh as she reached around, the whole mass wobbling as she squeezed.

In her mind, she could almost feel her own tender massaging, and her nipples’ hardening in response, their tips digging into the soft underside of her hooves. Then, there was the weight as she lifted one teat up—the way it sloshed back and forth in her grasp. She pressed it against her torso, until the nipple pointed right up at her, with a single bead of white liquid perched invitingly atop it. That imaginary Cadance leaned down and licked the milk up, her nipple electrified with pleasure as her warm, wet tongue slid across. Then, she pressed her lips to it and suckled, drawing more out. Cadance savored the sinfully sweet, obscenely creamy taste of her own milk—then, all too soon, found her mouth was full. So she swallowed—the slight motion of her jaw making the whole teat wobble again beneath her—and continued suckling. Between the flow of milk and the touch of her soft lips, her nipple was practically singing with pleasure, while Cadance swallowed mouthful after mouthful...

Back in reality, Cadance shook her head and scowled, dismissing that lewd fantasy. Now wasn’t the time.

Her face still flushed, Cadance stood up, only to discover firsthoof that it truly was possible to have teats too big. Their sheer size was pushing her hind legs even further apart. Even while squeezing her haunches as tightly as she could—squishing them maddeningly into the side of her teats—her stance was too wide. If she could still walk in this state, it would only be at a slow waddle.

Blushing harder, her pink face somehow becoming even pinker, Cadance spread her wings and took to the air. She wobbled in midair from the weight at her crotch—and her teats, hanging free, shook even more than before.

Cadance rounded the column—the same one she had smacked into mere minutes ago—and suddenly found Flurry Heart. She, too, was flying. She collided with her mother’s face, then held on tight, squealing with joy all the while.

Cadance reacted quickly. In a blink, she enveloped Flurry in a strong telekinetic field; in a second blink, she cast Fledgling’s Forbearance on her daughter. Then she let out a long sigh.

Crisis averted, Cadance thought. Aloud, she said, “I got you now, you silly filly!”

Flurry waggled her stubby legs in the air and replied, “Bee bee bah dah!”

“Yes,” Cadance said. “And don’t you forget it.”

Flurry yawned.

“Aww,” Cadance said, “are you tired? Is my precious little Flurry all tuckered out from running around and recklessly casting magic? Well, I know just the thing for that.”

She teleported both herself and Flurry back to the nursery. Flurry made no protest as Cadance laid her down in her crystal crib; less than a minute later, she dozed off. Cadance gave the sleeping foal a warm smile while she activated the alicorn-containment runes that Twilight Sparkle and Sunburst had very helpfully installed on the crib.

Cadance finally landed—and a sudden bite of coldness made her eyes widen. It took all of her self-control to refrain from yelping at the sensation (which might have woken Flurry). The cause was obvious. The crystal floor of the castle was cold, as usual; Cadance’s teats, which had grown more sensitive with every inch they inflated, were now massive enough to touch that floor, even while she stood up. In fact, as her boobs continued to grow, squishing further against the floor beneath, they were beginning to push her hips up.

Yeah, I really need to do something about those, Cadance thought. But she would have to do it in another room, or she risked waking up Flurry. And Cadance didn’t dare teleport away or even fly—again, for fear of waking the foal. Which meant the only option was to walk out, dragging her udders across the tantalizingly cool floor every step of the way.

So she set off towards her own royal bedchamber, while her face lit up with an even more furious blush. And, as she anticipated, her walk was really more of an awkward waddle, thanks to her boobs. She swung her hind legs as far out as she could, but even so, she had to squish those teats out of her way with every step. Moving at such a slow pace, who knew how long it would take her to get to the next room—and how much bigger she would grow in the meantime?

So many sacrifices, Cadance thought with a smile. Mother of the year: that’s me.

The floor was just as cool, but her teats were growing warmer. Her nipples were rock-hard, now; Cadance jokingly wondered whether they were carving twin grooves in the floor as she went. Then she glanced back and boggled at what she saw. There were two lines on the floor—but a second glance showed that these weren’t gouges. Rather, they were thin streams of white liquid: milk. Cadance noticed, for the first time, the moisture where her teats pressed against the floor. On a whim, she flexed her hips, squishing her boobs even harder against the crystal below. She savored the pressure inside, and the spreading wetness beneath. She resumed her waddle towards the door, leaving a slightly wider trail of milk behind her—and her rear hooves no longer landing as heavily on the floor.

Just a few feet away from the door to her own room, Cadance tried to take a step, but found her rear hoof just kicking against the side of her mammary. A second later, her other rear hoof also lifted off the floor, of its own accord. Her teats were now large enough to push her hindquarters into the air, while also pushing her hind legs out until they couldn’t reach the floor at all. Cadance wasted about a minute kicking her legs in a futile effort to get those hooves back on the ground. She only succeeded in squishing her legs into those teats, setting them wobbling harder than before—and her own backside bobbing up and down atop them.

With a sigh and a smile, Cadance continued towards her bedroom, by planting her forehooves on the ground and pulling herself and her huge boobs forward. Now that her hind legs were just hanging uselessly, the weight of Cadance’s entire backside rested solely on those huge, fleshy globes. The pressure of her teats, sandwiched between her haunches and the floor—and the cool smoothness of the crystal below, as she dragged her teats inch after wonderful inch across it—was clouding Cadance’s mind now. Her breath came out in pants, and sweat darkened her coat, as she pulled her jiggling, sloshing self right up to the door.

Even though this was a double-wide doorway, Cadance could tell that it would still be a tight squeeze. She dragged her withers past the threshold before she felt resistance. Her teats, predictably, were caught: at their widest points, they squished out a foot past the edge of the door on each side. It’s now or never, Cadance thought, because they’re not getting any smaller. With her forelegs, she pulled again, harder. With her hind legs, she kicked and squeezed her boobs, keeping their wobbling mass in motion. It worked. Slowly but surely, her mammary flesh sloshed and squeezed through the constricting doorway. The pressure made Cadance pant even harder; she had to fight the urge to moan lewdly at the waves of pleasure washing from her teats into her brain. Finally, the last resistance gave away, and she slid all the way into the bedchamber, closing the door behind her.

Cadance simply rested for a bit, panting while her teats continued wobbling, and her backside wobbled with them. “Oh, Princess,” she moaned, “why does this feel so good?”

Then she took a deep breath, lit up her horn, and began casting the counter-spell. “Let’s see... Mmmmm... form the casting circle... Oh yeah... add three vertices... Mmmm! ... convert to hexadecimal ... Mmmmmmmm... close the polygon, and that’s it!” The light from Cadance’s horn circled around her, then surrounded her mammaries in a gentle glow. The effect was immediate... and not what she was hoping for.

Cadance’s teats grew even faster, at an explosive rate. They tripled in size in the few seconds it took her to realize this wasn’t supposed to happen; they doubled again on top of that, in the few seconds it took her to recall the spell. Cadance shook her head and took stock of this new development. She was resting atop a pair of teats, each one five or six times the (previous) mass of her entire body. Walking was completely out of the question, now. Thanks to her new size, Cadance couldn’t reach the floor with any of her hooves anymore—her forelegs simply dangled against her teats, while her hind legs squished deep into their sides. Her whole body rocked back and forth slightly, from the sloshing inertia of her boobs beneath. A puddle of milk had formed beneath her, and was still spreading. And Flurry’s original spell was still in effect: Cadance could feel they were still growing at that original pace.

It was obvious what had gone wrong. Cadance had botched her counter-spell because she was mentally compromised: distracted by her own arousal. So the solution was equally obvious. She just needed to scratch that itch, then her mind would be clear enough to use magic properly. So Cadance dropped all restraint, squeezing and kneading at her teats with reckless abandon. “Oh, yes, I’m a naughty girl,” she moaned while thrusting her haunches, setting her entire mass wobbling harder than before. “Naughty, naughty...” She squeezed, savoring the sensation as her hooves sank deep into her soft mammaries. “Naughty, naughty, naughty...” She scrunched her eyes shut, arched her back, and...

“No,” Cadance said with a sigh. She could tell this just wouldn’t be enough. All this self-groping was fine for getting her fire burning, but it seemed that her relief could only come from something long and hard between her nethers.

And as luck would have it, Shining Armor chose that precise moment to enter the bedchamber through the other doorway. His sleep schedule still hadn’t recovered; his baggy eyes and disheveled mane were evidence of that. And now, if he was at all surprised to see his wife perched on a pair of ten-foot diameter crotchboobs, he certainly didn’t show it on his dazed face.

“Darling!” Cadance nearly shouted. Then she put on her most sultry smile. “I could really use your help with this, dear.”
