Applebloom struggles to fit in at college—literally, given her enormous size as a result of an oversized Apple family growth spurt. Her cousin Babs helps make her a little bit more comfortable.

Applebloom is a big mare. She can't help it. Apple mares have a tendency to grow much larger than the average pony, and Applebloom is one of the largest of them all. Unfortunately, this means she has a hard time fitting into new places (quite literally)…like Manehatten University, her new home away from home.

Fortunately, her cousin Babs Seed is living in the dorm room next door. And she just so happens to have the perfect plan to show her cousin a little bit of college fun—especially given 'Bloom's huge, sexy figure and her own feminine curves.

Tight Fits

Walking around was hard when you were eleven feet tall.

Oh, Applebloom had dreamed for years of what it’d be like. Covering yards with a single stride. Making the ground tremble beneath your feet. Smirking down at the little ponies who had to all but run to keep up with your walking pace.

Of course, now that she was actually enormous, she’d come to realize a somewhat hidden drawback of the whole “being gigantically huge” thing: Most buildings were pony-sized, and she was...anything but.

Applebloom winced as she stepped on yet another backpack. This one, at least, had been strewn lazily in the middle of the lecture hall’s staircase, but any other student would have stepped around it easily. Between the massive width of her size-sixty feet and the way her enormous breasts filled up pretty much the entire lower half of her vision, she hadn’t been able to see it. It crunched rather loudly beneath her one-tonne weight, and she flinched again when everypony turned to look at her.

“Sorry,” she hissed in a vague, downward direction, hopefully toward the student whose bag she’d crushed. Then, somewhat unsteadily, she continued making her way forward down the stairs, struggling to keep her mind off of the oodles of stares burning their way into the back of her skull.

Another other pony would have been able to trod on that backpack and get away with little more than a dirty look. But Applebloom wasn’t exactly most ponies. Eleven feet and change of huge, overgrown mare, she drew every eye in every room without even trying. All she had to do was duck through a doorway—a task which had only become more laughable when she’d realized that crawling through doors made it easier to fit her gargantuan bust than did crouching—and every gaze in the room would instantly be on her.

As she made her way down toward the front of the lecture hall, Applebloom knew that every eye was on her. She was acutely aware of every inch of exposed skin on her body, too—of which there was plenty. Rarity hadn’t actually had enough time to prepare a full-sized wardrobe for her before she’d departed for college. As such, Applebloom was stuck with some of Applejack’s old clothes. At nearly nine feet in height, Applebloom's older sister was nopony to sneeze at. But ever since her own growth spurt, Applebloom’s size had outpaced her “little” sister’s to the point where she looked rather as if she were wearing an outfit made for a foal.

Which she may as well have been, to be perfectly honest. Everypony was tiny to her now. Each one of her massive biceps was as thick around as a normal stallion’s torso, and that was without being flexed. It was a constant exercise in control to keep from tensing her muscles; Applebloom had enough experience in that department to know that Applejack’s shirts would tear like paper if she stretched them by so much as an inch. Even Applejack’s largest blouse only covered her chest, too, her titanic tits stealing so much of the fabric for themselves that her sculpted abs were on full display. And her nipples still showed through the material, far too big (and often, far too hard) to possibly be concealed.

The steps in the lecture auditorium had been built for a pony of ordinary size; to Applebloom, she may as well have been walking down a ramp. She was very careful not to slip, being acutely aware of just how loud a thud she’d make—and just how much property she was likely to destroy—if she slipped and fell here, right in front of everyone. A near-permanent blush was affixed to her cheeks; it was both a product of her constant concentration and a perfect consciousness of the weight swaying between her legs.

Her stallionhood. Her proudest possession, and certainly her most obvious one. It was large enough to make full-grown stallions feel short, rather than simply small. When fully erect, it reached above Applebloom’s head, and was wider than her neck. As it was now, it lay flaccid atop a pair of heavy, sloshing balls the size of exercise balls, nestled in a pouch that concealed only the lower third of her package, and revealed the top side of her shaft to anypony who bothered to look.

It was absolutely, incredibly obscene. The dean had been willing, though perhaps not happy, to accommodate her certain...difficulties with more modest clothing. The particular needs of Apple family mares, he’d told her and Applejack (with his neck craning back to meet their eyes), were not...unknown around Equestria. He’d let her off with a promise to try and keep her modesty as best she could...though not before she’d left a damp stain of precum on his carpet as wide as he was tall.

With an enhanced size came certain enhanced needs. And as much as the dean may have thought himself prepared for Applebloom, no Apple mare had ever been nearly as endowed (or, overall, large) as she was. As such, by the time she made it to the bottom step of the auditorium, Applebloom was doing her best to ignore the heavy sloshing of seed in her nuts, biting her lip as she pushed the whispering throbs of arousal out of her mind.

Distracted as she was by the thousands of little tenses, flexes, and throbs across her body—each one carrying with it the tingle of strength, of size, of arousal—Applebloom completely neglected to remember to sit on the floor when she took her seat. That was the entire reason she’d come down to the front of the auditorium, after all; she was just too damn big to fit in any of the regular seating rows.

And, she remembered in horror, mere instants before her amazonian rear touched down, too damn big to even fit in the seats themselves.

There was an awful crunching noise.

Her blush brighter and redder than ever before, Applebloom did her best to pretend not to notice the stares of her classmates, or the sudden glare of her professor. She could feel the crumbled ruins of the (now deceased) two—no, three—seats that she’d attempted to use crunching beneath her. Her ass was huge and muscled enough that she could barely even feel the debris underneath, but the seats had certainly felt her.

“Ahem.” The professor, an academic-looking stallion with a greying mane and rather severe eyes, stared at her for an additional few seconds before turning back to the board. “Now, the proper application of double integrals exists mainly within—”

Applebloom did her best to focus on the lesson. Her hands were too large to easily use a pen or quill to take notes nowadays—though Twilight had promised to mail her a special Griffon feather as soon as she got her hands on one—but she’d always had a good memory, anyway. And the lesson was interesting. There was only one problem. Her body seemed to have found a much more interesting subject to pay attention to.

Itself.

Her sleeves were tight around her arms, the overstretched threads ready to pop with the barest flex. Her nipples were pressed tightly against the fabric of her “shirt,” and every breath she took pushed them even further forward. Applebloom sucked in a breath as she felt the fabric of her blouse brush against one rock-hard nipple. At this size, every part of her was sensitive enough to be an erogenous zone in itself, and the tightness of her clothes was absolutely not keeping from reminding her of how hot her new size made her feel.

Her monstrous cock throbbed, and Applebloom nearly moaned. She’d overslept that morning, and had to rush out to class without eating a crumb. A body this big took lots of fuel to run...though it also needed another kind of attention entirely to work properly. She hadn’t emptied her balls that morning, caught between a rush to class and a sense of embarrassment over overflowing the bathtub the previous night. Yet from the half-drenched sheets she’d woken up to (multiple pairs, that was; at her new size, Applebloom slept across a quartet of full-sized mattresses laid directly on the floor), it was clear that going without unloading this batch of seed wasn’t a particularly wise move to make.

Sweat beaded on her forehead. Her lower lip trembled. She did her best to pay attention to the formula the professor was deriving on the board, but the tightness of her pants around her package just felt too good. She felt her mega-cock stiffening, slowly at first, then swelling longer and thicker by the second. She heard the threads of her pant legs creak, the pouch of her panties groaning as her titanic shaft nudged its way down her thigh.

Shivering with arousal, Applebloom found herself flexing her thighs, and whimpering as her tree-trunk legs bulged against her massive, churning nuts. She hadn’t even noticed when she’d begun, but she’d started stroking her balls, one big hand gently cupping the side of her four-foot ballsack as its contents sloshed and churned within. Her dick slipped further and further down her leg, its huge, black flare visible to the entire world as it drooled precum steadily onto the floor. Applebloom found her steady pants turning to stifled moans, her nipples stiffening in time with the rhythmic pounding of blood through her swelling cock—

“Miss Apple!”

She stiffened instantly—as did the rest of her. With a loud ri-i-i-i-p, her monster of a member tore its way up half of her pant leg. The rest of her pants, thankfully, stayed on. All the same, a full half of her left nut was now visible to the front of the room. Even resting on the ground, it came up past her professor’s waist, and the rest of her (sitting down!) found it all too easy to look down on him as he approached, fuming.

She stifled another gasp as a glob of pre bigger than most ponies’ heads splattered onto the floor, her shaft lurching between her legs as another surge of pleasure tingled up her spine. She groaned helplessly, her eyes fluttering as her red-faced professor stalked up to her.

“I will not,” he bit out, “allow this manner of...lewdness in my classroom! Is that clear?”

Applebloom swallowed another moan. From here, she could make out just how tiny the teacher was compared to her—compared to her cock, even. He was a little thing, even for a stallion, barely hitting five and a half feet wearing shoes. She doubted he’d even come up to her medial ring if she were fully hard. Her cock throbbed again, and she bit her lip, struggling to push away images of the cute little stallion wrapping his arms and legs around her shaft, his pitiful erection grinding against her own as she groaned in pleasure, the floor rumbling beneath her as she grew and grew and grew—

At least snapping out of that particular fantasy wasn’t too difficult. “Yes, sir,” she said quickly, blushing redder than he was. He scowled and wagged a finger up at her. If she hadn’t felt so embarrassed, it might have been rather amusing: this tiny, skinny little stallion trying to discipline a hulking amazon of a mare easily twice his size, equipped with a pair of breasts that each weighed more than he did and a cock that would have made him look short. “Sorry, sir.”

“Sorry, indeed!” he sniffed. “Now, I’ve been informed of your condition, but I will not have you taking care of it in my class! You may use the facilities if you require it, but not my lecture hall floor!” He glared at her over his spectacles, his face redder than a cherry tomato. “Is that quite clear?”

“Y-y’all got it,” she stammered. Her cock throbbed again, and another jet of pre splattered onto the floor. Trembling, Applebloom realized that she had to get out of there—before she exploded all over the chalkboards, the desk, and the professor himself. “I’m really sorry.”

“I expect so!” he mumbled. It was only the barest luck that kept her from noting the bulging tent in his own pants. “Now,” he continued, turning back to the board, “with my previous theorem in mind, we can see—”

Applebloom fled the auditorium.

Going to one of the bathrooms wasn’t an option. She’d barely even fit into the stall the last time she’d tried, and she did not want to leave a small lake of jizz flooding the math department’s public restroom. Home, it seemed, was the only option.

She made her way across the cut, a square of green surrounded by the grey towers of Manehatten. Pushing her pace to a light jog left her more confident that she’d at least make it to her room, but in the meantime, the rest of her was on full display. She passed couples that came up only to her waist, professors that could scarcely keep their eyes off of her bouncing, throbbing package, and students that looked like she could snap them like a twig. And she could, probably, if she weren’t careful. Applebloom had uprooted entire apple trees during the last harvest by mistake; to a mare of her size, everything was small and weak.

The Manehatten skyscrapers, at least, were the one thing left that could make her feel small. And they provided something for her to look at—something up, above her, so that she didn’t have to see her massive jugs blocking her vision of the ground, something to distract her from the constant sloshing of her nuts as they grew and swelled with seed. She felt her shaft pushing further down her leg and bit down on a moan as her sizeable ass bounced and flexed with the tensing of her thighs.

Every part of her was in constant motion, from the pony-sized pouch that bounced and swayed between her legs, to the hundred-pound tits that jiggled and rippled with each smack against her belly. Each collision between her feet and the ground send ripples of motion through her body, her muscles tensing reflexively and her cock and tits reverberating with waves and counterwaves of pure, unadulterated size. Everypony on the cut could see every part of her moving like a drunk filly at a dance party, could see her cock throbbing larger, longer, stiffer with each splurt of precum she left on the sidewalk behind her.

At this point, at least, she’d become fairly adept at squeezing through her dorm’s double doors. The stairs proved a bit challenging, having been sized for a pony half her size, and the elevator was absolutely out of the question, but she managed nonetheless. Thankfully, her room was just on the second floor; had she been confident in her ability to do so without breaking the window (and shattering the rest of the wall), she might have been tall enough to just heave herself up into her room from the ground outside.

She recognized the smell of her dorm instantly. College had proved itself to be full of a very particular kind of musk...and one that was unfortunately very interesting to her new biology. With so many ponies crammed together, it was inevitable that there’d always be the scent of a mare in heat somewhere on the floor. Sweet, feminine smells just begging for a good rutting mixed with spicier, masculine musks that Applebloom’s stallionhood yearned to put in their place. The Hendercolt dorm had never seen a stallion quite like her, but her body knew it was the biggest, strongest, most virile thing the building would ever see.

Somewhat shakily, she turned away from the common room—once or twice, she’d tried to force herself to ignore the sound of moaning coming from there just past midnight, and found herself jizzing all over her bathroom not minutes later—and toward her own room. The dorm had tall ceilings, but even so, she had to bend over to avoid scraping her head on the ceiling. It still scraped along the top, of course—she’d never fit inside a normal room again, not without crawling on her hands and knees (a position which, amusingly enough, put her eye-to-eye with most normal ponies)—but at least she didn’t break through to the third floor when she stood up. Which she would have. The ceiling tiles seemed awfully fragile.

Occupied with the mounting tightness of her shaft, and the sloshing of her balls, it took Applebloom a moment to notice that somepony else was standing outside of her door, working a key into the lock beside it. It took her another moment to recognize that pony. Not everypony was distinctive from the back, but she’d have recognized that half-colored purple mane anywhere.

“Babs?” she gasped.

Applebloom’s voice may have been an octave or so lower than when she’d last heard it, but the smaller mare seemed to recognize that familiar country twang just fine. She paused, her key halfway in the lock, and turned to face her. Babs Seed looked up—and up, and up—to meet Applebloom’s eyes and gaped.

“No way,” she said. Her eyes lit up. “Lil’ AB?”

“Not so little anymore,” Applebloom replied with a chuckle. She gave her right arm a light flex, and then instantly remembered just how tight her sleeve was around her bicep. Too late. The fabric tore right up to her shoulder, ripping loudly around her bulky muscle like tissue paper. She blushed.

Babs eyed her arm approvingly. “I can see that,” she said. She was a stocky mare, not fat, but solid, built with layers of muscle and a trim layer of fat around her chest and belly. Her hips, though...those hips could have laid waste to an army. Wider than her shoulders, and looking plump, supple, and soft, they were the kinds of hips that any stallion would have loved to get his hands around.

As Applebloom scanned Babs’ figure, she felt a twitch at her crotch. Her stallionhood, evidently, had not forgotten that it still had certain needs of its own. Already, she could feel another puddle of pre pooling around her left foot, mere inches below where her fat, black flare hung lazily above the ground. She forced a grin onto her face and hoped that she’d be able to take care of it soon.

Babs smirked up—or rather, across at her. The bulging pouch containing her balls was big enough for her to lay on, and there was an unmistakable note of interest in her bright green eyes. “I didn’t even know that you were going to Mane U,” she said, her clipped city accent showing through. “Or that you’d hit your growth spurt.”

“Well, I am,” Applebloom said, only somewhat awkwardly. She tried to grin down at Babs. “And I did.”

Babs whistled slowly. “You certainly damn well did.” Applebloom blushed.

“I didn’t even know that you were living next to me,” she said. “I mean, I know that I’m only a freshman, but I figured I would have at least noticed.”

Babs shrugged. “Eh. I’m a night-workin’ gal,” she said. “And I’d wager that you’re a good lil’ country filly, right?” She winked. “Up by sunrise, beddy-byes by ten?” She snickered at the pained look in Bloom’s eyes. “Thought so.

“But anyways,” Babs went on, taking a step forward. She had a rather...large pair of breasts on her, and they bounced enticingly against her chest as she moved. They were each wider across than both of Applebloom’s fists put together, and she had big hands. She could almost make out the outline of Babs’ nipples pressing against the fabric of her sweater. “I’m glad to see you ‘round my hometown now. And not just ‘cuz you’re my cousin.”

Oh, gosh. The way that Babs was looking at her right now could only be described as hungry. Abruptly, Applebloom was reminded of a time in their childhood when Babs had dressed up in a wolf costume and chased the Crusaders around town for an hour. That look was that of a mare who knew what she wanted—and what she wanted was a prime cut of thick stallion meat. Applebloom gulped.

It didn’t help at all, really, that Babs’ figure was just as...enticing as her own, albeit in a completely different way. Applebloom’s tits may have been nearly comically large, but Babs’ drew the eye in an easy, confident way. They were a nice, round pair of melons that jiggled enticingly whenever she stepped forward, and strained at the bounds of her sweater. Applebloom wondered privately just how much they oozed out of her undoubtedly too-small bra when she took the sweater off.

And her hips… By Celestia, she just could not get over those hips. They were incredible. Those thighs, so thick that they rubbed together when she walked, putting any possibility of a thigh gap firmly to rest. Babs Seed had a true pear shape, with an ass, hips, and thighs to die for—and Applebloom found her dick really liking what it saw.

“Seriously,” Babs was saying. Applebloom barely even heard it, caught up as she was in a reverie of lustful fantasy and a deep, throbbing need for release. “You’ve grown up all over. You Apples get so ridiculously huge, and I don’t even think I’ve seen a single one of ‘em get nearly as big as you. You’re fuckin’ enormous, AB, and I sure ain’t embarrassed to say that it just makes me feel a little bit—“

With a moan, Applebloom felt her pants give way. After a full morning of straining, the fabric had simply been stretched too much. Her hard shaft, now fully engorged and throbbing, tore its way out of her pants and rocketed up into the air. It was tall enough that it actually smacked against the ceiling at the top of its arc, just after its girth had lodged itself firmly between her massive breasts. Unable to stop herself, she groaned with a throaty, needful pleasure, a fat glob of precum bursting right over her muzzle.

“—turned on.”

Babs blinked. Applebloom groaned—and then froze. She’d had her share of “accidents” by now, but somehow, doing it in front of her favorite cousin made it seem all the more awkward.

And then Babs smiled.

“Damn,” she drawled. “You are a big filly. Dunno if I could even fit that thing through my front door.”

Applebloom chuckled awkwardly. “Um...yeah. It’s, uh, a lil’ big.”

“A little?” Babs scoffed. “S’bigger than me! Damn, Bloom, just how pent up are you?” She quirked an eyebrow at Applebloom’s look of surprise. “I know how bad Jackie can get at family reunions, and you’re a good two heads taller than she is.”

Applebloom blushed. “...It’s pretty bad,” she admitted. “I didn’t, er, take care of it this mornin’. And I always feel so darned self-conscious about it in class, ‘cuz I can feel everypony staring’ at me. S’not like the farm.” She stared at the floor, which was admittedly a long, long way away. “Guess there’s just way too much of me, ‘cuz I can’t help but likin’ it...and that just makes it worse.”

Babs chuckled throatily. “Now that’s a problem I wouldn’t mind havin’,” she said. “I gotta say, Bloom—I don’t mind catchin’ a few eyefuls myself. And I’m liking what I’m seeing.” She gave her much larger cousin a wink.

“So if you’re so pent-up,” she went on, smirking, “why not crash in my room for a bit? I can’t say I haven’t helped out some of you freakin’ huge Apple mares before. And besides”—she licked her lips—“you’re much bigger than your older sister was.”

Applebloom’s blush only deepened. “R-really?” she asked. Stammering didn’t quite fit a hulking amazon of her stature, let alone one with a cock more than half as big as she was. Somehow, it managed to sound somewhat adorable nonetheless. “You—you’d wanna—“

“For my fillyhood best friend?” Babs smirked, gave her oversized rear a slap, and turned the key in her door’s lock. It swung open invitingly, and she stepped inside, making sure to give Applebloom a good, heaping eyeful of her substantially endowed figure. “Bloom, it’s takin’ every ounce of willpower I got not to just pin you right now. So why not squeeze in here so you can pin your big ol’ self to the floor for me?”

And with that, she slipped inside, leaving Applebloom staring after her fat, bouncing ass, her swaying hips, and her grinding thighs. A splurt of pre against her face brought her back to reality, and she followed Babs inside.

And squeeze in she did. The doors in the building hadn’t ever been sized for a giantess of her caliber, and Applebloom really didn’t want to make a bad impression by shattering Babs’ entire doorframe...especially because if this went any further, they’d have a hell of a hard time keeping things private. Not that she especially minded, she realized, flushing. Trotting around town with an amazonian body and cock that not even the largest clothes could conceal tended to make even the most conservative Apple mare into something of an...exhibitionist.

Before she could stray any further down that particular line of thought, she turned her attention to squeezing herself through the doorway. Her massive, soft tits got caught on the door—as expected—but she managed to shove them through with only a few cracks to the frame. Crawling was pretty much her only option at this point, and she had to say that it was really something how her seven-foot cock stuck out in front of her, all but announcing her entry into the room with its fat, throbbing erection and constant drool of precum.

She would’ve felt almost bad about staining her cousin’s carpet with pre if Babs hadn’t been drooling at the sight, not-so-subtly fingering herself through her sweatpants. And the way Applebloom’s heavy balls dragged against the floor as she crawled just felt...unf. She could feel them growing heavier, swelling larger and fatter with seed with the lightest breath of stimulation.

Oh, yes. This was definitely going to be...well, explosive.

After cramming herself into the tiny little dorm room, Applebloom leaned herself up against the far wall, which thankfully held up under her weight. Even sitting down on her (admittedly very large and very muscled) rear, her head was two-thirds of the way up toward the ceiling. If she’d stood up, not only would she have broken through the floor, she very well would’ve stood up into the next floor up to boot.

Applebloom groaned. Her cock bobbed below the shreds of her ruined pants and pouch. Her shirt tensed around her arms and breasts, the fabric drawn tighter than ever around her bulging body. Babs eyed her with sultry eyes from beside the door, then withdrew her hands from her pants.

Somehow, she’d managed to extricate her panties from her legs—while still wearing her jeans. “Lookit ya,” Babs said with a smirk. She stepped forward, her thick thighs grinding together as she lazily spun her lace panties around her pointer finger. She closed the door behind her with a kick, though it was doubtful that it’d even do anything to conceal the sounds they’d soon be making. “Fillin’ up the whole damn room. How do you fit anywhere, Bloom?”

“I...dunno,” Applebloom admitted. Admittedly, she was having a hard time processing any coherent thoughts at the moment. Her eyes were glued to Babs’ hips, a pear-shaped doughnut right above a pair of soft, chunky thighs that she didn’t doubt would feel like heaven squeezed around her dick. Her stallionhood lurched in evident agreement, splurting a fat glob of precum onto the carpet before her. Babs just chuckled as she sauntered forward, her swaying step causing her huge, fat ass to slap gently against the backs of her legs.

“Whoa, there, cowpony,” she snickered. “Looks like somepony’s a lil’ overeager.” She gave her rump a smack, causing it to jiggle wildly behind her. Applebloom found herself drooling a bit, eyeing her cousin’s prime figure with unconcealed lust. “Can’t say I don’t got the same, though. It’s been ages since I’ve had a real stallion in me.”

She was at Applebloom’s cock already. Her amazon cousin’s flare sat heavily on the ground, a fat, black cylinder that came up to her thighs and throbbed steadily, drooling precum onto the ground. Babs stroked it gently and Applebloom went completely stiff.

“Yeah,” Babs murmured, her smirk widening. “You’re pretty big. I wanna see just how big y’are, though.”

Applebloom groaned. The stimulation of Babs’ hand on her cock felt...indescribable. This mare knew what she was doing.

“Bigger than any Apple ever, huh?” Babs said, chuckling. “Twice the size of your big brother? Not-so-Big Macintosh? How’s he feel, bein’ shorter than his baby sister’s cock? A cock that’s gonna rut his lil’ city cousin silly in around thirty seconds…”

Applebloom moaned. Her cock flexed, and she flexed with it. Her muscles bulged, flexing to their full size as her body tensed in arousal and need. The rest of her clothes instantly tore off, ripped to shreds as her body expanded far past their capacity. Her enormous boobs flopped down onto her chest, her biceps swelling hugely as they were exposed to the air.

“Much better,” Babs purred. She straddled Applebloom’s shaft and gave her hips a little jerk. Applebloom found herself groaning faintly, too overcome with arousal to even put together a coherent sentence. “Now that’s my big ‘cuz.”

“...Babs,” Applebloom grunted. Another thrust of Babs’ hips forward made her bite her lip; as Babs flexed her huge thunder thighs, choking her enormous shaft, another splurt of pre the size of Babs’ head burst over the carpet. “You...you wanna take me? All of me? I—I’m awful big.”

“Oh, you bet I am, girlie,” Babs purred. “No worries, Bloom. I know what I’m doing.” She pushed herself back and rotated, her fat butt cheeks squishing out over the pre-slick surface of Applebloom’s flare. “And I’m gonna take every last drop of your cum, y’hear?”

Applebloom wasn’t in any reasonable state of mind to argue. Once Babs had lined her marehood up with Applebloom’s shaft, she nodded to herself, grinned, and slowly pushed back.

Her thighs flexed, her thick legs extending as she pushed herself back and downward. Applebloom felt one edge of her flare stick inside of something hot, dripping, and moist, and then the full head, as Babs forced her cunt to stretch over the entirety of the flare’s curve. By the time she was done, Babs was squatting, an entire three inches of Applebloom’s cock shoved impossibly into her snatch.

Babs groaned, rubbing her belly. “Fuck. Now that’s the stuff.” Applebloom moaned, a low, rumbling sound, and a huge glob of pre burst in Babs’ belly, distending it. Babs licked her lips and patted her gut, grinning when it sloshed.

“Good start,” she grunted. “But not enough. Pick up your cock for me, wontcha?”

Applebloom blinked. “Uh—”

“S’too big,” Babs said. “Can’t pick that monster up myself, can I?” She smirked. “You’re gonna have to do it, big girl.”

Slowly, her mind still drowning under the hot, aching need of penetration, Applebloom picked up her shaft in both hands and picked it a foot off the ground. Babs grunted, steadying herself and moving her squat up a few inches. Then, taking her tongue between her teeth, she began to walk herself backward, taking in inch after inch of Applebloom’s monster cock. Her belly kept bulging out further, more and more of her cousin’s member dominating her frame by the second.

There was a look of vacant, mindless pleasure in Babs’ gaze. Her tongue lolled out of her mouth, a line of drool slipping down her chin as she pushed her cunt back. Her eyes were half-lidded, and she panted in time with the steady, resounding beat of Applebloom’s shaft. Unfortunately, though, she soon found that she could go no further.

“I—nggh.” Babs grunted in frustration, glancing back over her shoulder. Before her, a good two and a half feet of Applebloom’s cock jutted out from her stomach. She curled her hands around it protectively, stroking it gently as her insides stimulated Applebloom’s flare further. “Dammit. That’s barely a third. Gonna need your help for this one, AB.”

“Help?” Applebloom grunted. Her massive arms trembled, her balls sloshing as they filled further with seed. Oh, gods. She needed to cum—she needed to jizz so badly. There was just so much; her nuts felt so full.

Babs shot her a smirk. “Cocksock me, girl,” she said. “Celestia knows AJ’s done it to me enough times. I want you to rut me like a fleshlight, y’hear? I want every inch of your fuckin’ cock inside of me, even if you have to force it in.” She patted her belly, and grinned when she felt it slosh with another spurt of Applebloom’s pre. “Now fuckin’ shove it in me, okay?”

She was close enough now that Applebloom could reach her with either arm. Wrapping one oversized hand around Babs’ waist, Applebloom picked both Babs and her shaft into the air. The simple force of the motion forced Babs’ impossibly stretched marehood another two feet down Bloom’s length, the loud schlick mixing with Babs’ cries of pleasure as her belly bulged with four feet of gigantic, fat marecock.

“Yes…” Babs groaned. Her eyes fluttered, as did Applebloom’s above her. “F-fuck yes! Yeah, keep goin’!”

Applebloom was happy to oblige. Still holding Babs in one hand, and massaging her exercise ball-sized nuts with the other, she began to pump her little cousin up and down her length. Babs’ stomach bulged out hugely around her cock, even as jet after jet of pre forced her belly into a more spherical shape. It bounced and sloshed every time Applebloom shoved her back down and up her length, filling up further by the second.

Soon, Applebloom felt it: that mounting, inevitable, incredible tension. She grit her teeth, closed her eyes, and let it seize her. Babs squirmed atop her shaft with each pump, her constant groans and writhing only turning Applebloom on further. Her balls churned louder than ever, swelling up another third in size as they prepared for the ever-sweet moment of release—

With a primal cry, Applebloom felt herself erupt inside of Babs. Fully hilted inside of her cousin, she could see her cock rising far above Babs’ tiny form, distending her belly massively with a pillar of meat taller than she was. All the same, the first geysers of jizz only distended her gut more, volleys of spunk exploding inside of Babs’ cunt and painting her insides white. Babs screamed in pleasure, shouting as she came as well. Her already tight insides clenched and spasmed around Applebloom’s cock, milking the base of her giant cousin’s shaft for every drop of cum she had.

And every drop she wanted, she got. Applebloom groaned, twisting and writhing as she came an ocean of jizz inside of Babs. Gallons of her hot baby butter burst inside of Babs’ snatch, filling up her cunt with more seed than she’d ever dreamed another pony could take. She held Babs firmly around her cock, her cousin’s tight marehood acting as a perfect seal to keep every drop of cum inside her. Each pump of her cock sent Babs’ stomach soaring larger, at first plumping out, then rounding out, then swelling, exploding outward in size as Applebloom gushed enough jizz inside of her to fill a small pond.

By the end of it, Babs’ stomach was absolutely enormous, full and sloshing with cum. She groaned, tried to hug it, and found that it was even bigger than her. Gently, Applebloom lifted Babs off of her cock and placed her on her sculpted abs, each of which would have been the size of Babs’ fist. Babs’ soft body, from her thick, chunky thighs, to her huge ghetto ass, and to her now enormous belly, stretched so taut with cum that it looked ready to burst, was a sharp contrast to Applebloom’s perfectly muscled, bulging figure.

Babs groaned. She could barely move, being pinned to Applebloom’s torso by the weight of her own belly. Her legs twitched, her feet wrapped tightly around the base of her cousin’s shaft. “F-fuck,” she groaned, drooling slightly. “Now that’s what I was lookin’ for, damn it.”

Applebloom chuckled. She stroked her cousin’s belly lightly, feeling it squish, jiggle, and ripple in her big hands. “And that’s what I needed. Thanks, Babs.”

Babs grinned up at her, over the twin mountains of Applebloom’s breasts. “You—you got it,” she slurred. Then she glanced over her own mountain of a belly.

Or tried to, at least. “Fuck,” she grunted. “Don’t think I’m gonna even fit through that door like this.”

“Maybe it’ll digest overnight?”

“It damn well better,” Babs said. She slipped a hand under her belly and gave her succulent thighs a squeeze. “Gonna need to get these bad girls bigger. So thanks for all the protein, Bloom.”

She sighed, snuggling her head against Applebloom’s soft tits. “Say,” she said after a moment. “How long d’you go before fillin’ up again?”

Applebloom blinked down at her. “Uh,” she said. “One, maybe two hours, I think?”

Babs licked her lips and grinned. “Great,” she said. “How’d you feel about a round two in a bit, then? I can always like gettin’ even bigger.”
