The Littler, Now Bigger, Hornier Sister

~ III ~

Two Sisters in the Same Tub

Applejack grew accustomed to the shifting of the walls, their rubbery surface slowly becoming pleasant. The filly's tush now hugged her tightly, sure, but it also ensured she'd never be let go. Those fuzzy dams of lax flesh would warm and hold her—no matter how much the distant hips above dared to sway.

She was faintly aware of the creaking of wood softening into something different. The opening and closing creak of a door long since neglected. Applejack had curled into a ball and taking the crushing of softness as best she could. It wasn't that she'd given up... but had begun its path.

Then came the creak of metal and the gushing of torrents composed of water. Though the sound was muffled by the walls, the subtle hiss of the falls could make any natural waterfall whimper at the thought of comparison. How a change of perspective could alter everything.

“You're a good swimmer—ain't you?” The voice resounded from beyond the flanks and within. Horrible whispers and echo of the same soft voice. “Don't see why my butt has to house you longer than needed.” Her hooves thundered closer to the pouring of tidal waves. “Hope you're ready to make a splash, once-big sister!”

Applejack was faintly aware of her body pushed out from the confines of the filly's ass. Lifting her head, she saw mile-crevice part greatly as the edge of the sunny hoof appeared over the edge of the sloped flank. Her body slid out, intentionally, her body too spent. She only managed to raise her head.

Both of the pert lemon globes were perched against a sleekness of whiteness, narrow though thick, spanning the length of sea contained within a bathtub. Both flanks were wobbling from opposite sides from each other, broadening the gap in-between them, allowing the mare to slide out.

Golden strands of mane flew out from Applejack's eyes as she barrelled forward, faintly aware of wings before the rising of something absolute then consuming her. A splash resounded as the weight of her body doubled. There was water, swallowing her as she sunk, its warmth a last comfort.

Applejack sunk on her back and gazed through the ceiling of the water, the bridge of metal, a once unremarkable tap made monolithic. The pouring of oceans ceased from its depths as a yellow hoof turned the vaults above it. Though all that blurred as the tiny mare sunk further.

Then something great came. Giant enough as seas of water were consumed in taking her monolithic form. Applejack had reached the middle depths in the realm that existed underwater, staring off into the distance, unable to make anything of the tub.

The whole of the filly consumed the area underneath the sea, the massive size of her body spanning the whole of its depths, her happy muzzle brimming at spotting the tiny mare. Bloom's body then slid forward, covering the bottom of the tub—before rising up.

Applejack felt a sudden force of softness crashing into the underside of her body, pushing her upward with near terminal velocity. Her stomach swirled with slicing knives as the amber lands lifted out from the waters. The tiny mare was hacking out water before realizing she'd broken the surface.

It took a few moments of coughing for her lungs to clear. Seconds longer for her eyes to adjust to actual light and air. The tired mare rose on shakily limbs in a vain attempt to stand tall. The splashing of waves over a beach filled the air with its melody.

That wasn't a sound to be heard around here.

Applejack stood on the patch of wet, blond furs, tossing her muzzle around, trying to find a basis for her location. The ground had risen in a subtle hill that could only faintly be called plump. She ambled over to the side of the strange flooring, peering over the edge like one would do high up on a ship, spotting the surrounding water so far below.

And how it periodically rose up in waves gently slapping the sides of the yellow barrel.

“Don't think you and I have shared a bath in a long time.” Applejack felt currents of air rushing beneath the grounding of her hooves, leading like bound electricity to the giant, distant voice afar. She gazed across the fields, raising her head while she did so, coming to gaze at the hovering muzzle of Applebloom. “Though I guess you and Rainbow take baths all the time, don't ya?”

Applejack wasn't sure what to say. What to do. She turned her head in shame, eyes closing and teeth biting on her lips, unsure of how all of this should play out. Despite the water that now blanketed them—musk lingered richly in the air.

“What Rainbow and I have... it's something different from what you and I are supposed to have.” Applejack dared to gaze as the monolithic muzzle that hung afar, at how the filly so causally filled and laid back in the tub, holding her tiny body on the mere pudge of her belly. “And it's supposed to keep that way for a reason. This ain't right. But... you already got your fill of that, haven't ya?”

“I'm... I... I'm just...” Applebloom's face then turned to the side, the blond cliff of her cheek composing the fluffiest of a cloud. It slowly tinted with red. “I'm just tired of being left behind. We ain't like how we used to be. And nothing I do gets you to want to play with me again.”

Applejack inhaled deeply, as one does when truth places weight upon their words. “That's just the way it goes, Bloom. I'm entertin' a part of my life I've never rightly enjoyed before. And... I shouldn't be gettin' drunk on it like a do. But.... but...”

“But you just want to follow your interest—only thing that seems right.” Bloom turned her muzzle back and glared down at the tiny girl. “Even Mac lettin' you off the hook cause you want to enjoy yourself like a mare. Seems like the only thing that's right. That ponies ever want to do with each other. Feel good in all those strange places.”

Applejack stared down on the stadium of fuzz she stood upon. The tickles of furs hadn't been lost on her soles. Nor had the slow expanding and receding of the mass below her. How skin beneath it all warmed her body. That all of this was greatness and wideness was composed of her little sister's body. How it was living, moving, reacting to them both.

“Guess I was hoping for you to come into this stage a bit later in life.”

“Well I'm glad it happened now.” The authority in the voice, a genuine boost not aided by the gained size. “You and I haven't had any reason to connect. No reason to do anything but work together. A-At this age... it ain't like I can suggest we take a bath together like we used to. Can't even sleep in the same bed no more.”

Applejack gave a weak smile to the giant. “Price of growing up.”

“But those things are still the same with you and Dash, aren't they?” Applejack watched to the side as an arm lifted out from the depths of the sea, waterfalls cascading across its length, the sudden crashing of torrents nearly deafening to endure. “Ya take showers and baths and play with each other. Rough housin' like all of us used to. Even share the same bed—don't ya?”

Applejack blinked while craning her head back, seeing the hoof pass through the sky overhead before slamming into the ground behind it. The impact jolted her into the air for a second. It then settled in place—directly behind her.

“I... I ain't sure what you're—“

Applejack was stumbled out of words as the barricade of the behind hoof then pressed upon her back. Not with any force—though none was really required in the first place—and at a slow pace. The tiny mare, breaking into a walk, could move on her own will—one enforced by the moving hoof behind it.

“All the things that we used to do together,” Applebloom said as the bottom of her body disappeared further into the depths of the water, keeping the tufts of her chest above the surface, all while her chin graced the waves, “are now the things you do with Rainbow Dash. Ya always say things are different, or they've changed. But all I see is you still doing the same things as before.”

Applejack wasn't sure what to say about that as the giant muzzle of her sister appeared at ground level to her now. It felt like approaching the cliff of a mountain that was set against the ground. She barely retained its mass within her gaze. That sprawling grin of succulent lips drawing her attention.

Though she walked on her own, the hoof behind ensured she went where it wanted her to go and that, somewhere in the back of her mind, a part of her craved to be closer to those lips. Another wanted to be closer to the filly as a whole. So many contradictions rushing throughout her body.

Things weren't supposed to go this way. Even if the round wall of hoof was sliding only feet behind it—it should have been pushing her toward the destination. Her limbs should have quit and her mind set in determination to fight every attempt around her. Fighting wouldn't change anything, that she knew—but at least it would prove something to herself.

But her hooves only came to a stop on the summit of the filly's chest, seeing the mass of her head hover so close, straining her eyes to keep the sight within her gaze. Those eyes were pools in of themselves, and those cheeks could be used as playgrounds if one pleased. The sheer size of the once smaller girl was now a turn on in of itself.

“The way I see it,” Applebloom began upon noticing the mare on her chest, leaning her head forward, bringing her lips inches away from her. “Is that you want all the same things we once had. Ya just want them a little differently. And I'm not gonna be like you. I'm gonna enjoy myself early.”

Applejack could barely raise her head. “And... what if I want those things with someone else?”

“Then you won't get the same feelin' you get when you're with me...” The tip of Applebloom's tongue poked out from her lips like a giant serpent. The mass of its front swept across the narrow plushness of the tender flesh. “But I'll make you a deal. You... help me with whatever this is. You enjoy yourself too while you're doing it.”

Applejack opened her mouth—but the gales of the filly's voice decimated her squeaks.

“Don't think now you'll suddenly be any good at lyin', sis.” The cliff of the ivory chin crashed into the field of the chest, setting the swells of those long lips closer, a tinge of red rising on their plumpest portion. “Why did you move around so much in my rump? Not many ponies would like being placed inside of there. But you sure did move around a lot.”

“Because you—“

“And when I rubbed you against my crotch earlier? How come you didn't move against that one bit? Face it, sis. Maybe you do like playin' with me like that after all.” Her grinned sprawled into a smile reaching the furthest portion of her muzzle. “You play with me now. Help me with this heat stuff. After that, if you don't like it... I'll take you back to Rainbow.” Her chin rubbed in place while her muzzle twisted. “That's what you want, don't ya?”

Was there any point in considering this? It didn't seem like an option existed regardless of the path she went. Plus... it was hard to fight stable burn licked across her legs. That expansion of heat welling beneath her skin. Or how she was in a bath, on the chest of a gigantic filly, one that was her sister, all with sex thickening the air.

Maybe if things were different, if she were better, steadfast, then things would and could have changed.

But Applejack accepted her fate. No more trying or words or fighting back what was to occur. Something within her, a deeper quality, long since repressed had now infected the rest. All she could do was submit. Do this deed not morally right. Something also disregarded by the other sister—so long as they could be together, and both of them genuinely craving such a thing, then she did not care what the world would see when it viewed the two.

It was her hooves that took her forward, now without the call of a threat, but done by her own volition. Applejack approached the welling of those juicy lips as they'd been lowered enough for her to reach. Both could easily take her size and, even with them bound together, was taller than her stature.

But the tiny mare lifted onto her hind legs and fell forward into the giant, pressed-together lips, sinking into their fluffiness. Their elasticity partly held her back, the warmth of their surface a pleasant glow on her skin. Giggles resounded from the cavern behind them.

The amusement of a filly that won.

The swollen pillows billowed beneath her frame. Some of their softness snaking against her chest and belly, kissing the place—like Applejack had done to her so many years ago. The contact was loving, the starting of a connection between them. Only now, however, it started a way to a different location.

Applejack couldn't see much through the golden locks strewn over her eyes. Only of the swell of the upper-lip rising and lowering nearly like a waterbed. Their plushness always kissed her skin without trying. Their warmth always warmed her in a way beyond temperature. And something else was beginning to build within her—the kind of build-up needing to be expressed before it exploded into something different.

Something big poked against her belly. Gravity changed, and Applejack clung all four limbs to the lips. The filly continued to giggle as her titanic head leaned back, forcing all the weight of the mare onto her lips. She sunk deeper into them. Her weight seemed delectable to the giant.

The lips then parted, slightly, though still massively to the tiny. Out from its depths came the pink of the serpent again. It poked against Applejack's belly and, if she acted on intrinsic, would have grappled to it instead. Rather it swept against the underside of her body. The taste of pumpkin coating her fuzz. Though the tongue dove to the place between her legs.

Applejack threw her head back and beat tiny hooves against the wide expanse of lips, the impacts nothing as they sunk mere inches into the clumps of softness, nothing but tickles to the giant. She clenched her hind legs together to bar the intruder—it dived inward all the same, parting her doughy thighs, finding the slit of an inch as a taste-bud crept inside.

The tiny mare lost. Her thighs wrapped against the velvety appendage, hugging it to the slope between her legs, pressing it tightly against her crotch. Its heat and moisture caused her hips to stride across it, a grind followed by another, losing her mind to the rhythm of her body.

Bloom watched with an arched eyebrow to the happenings of the little mare. Whenever she attacked her special place was when her body started to take over. It made sense. It felt mutually as good when she'd lodged her sister in her own personal chamber. That, and pleasure came that spot knowing she had stuck Applejack within the confines of her rump.

So all pleasure came from that place, and that most things were excused if one wanted to play with that spot with another—no matter the setting. Bloom kept clicking her tongue to strike that place, mindful of the different moans squeaking out, trying to net the ones that sounded pleasant—not the ones sounding pained.

While this was happening, however, one of her other hooves snaked down the length of her filly body. Creating waves in the water as caressed down the side of her stubby barrel. Touching herself didn't evoke any sensation. But imagination she was rubbing her tiny sister across her body, underwater, lit fires to the tips of her emerged furs.

The same kept true when that hoof reached her bottom. Not only was the angle different, but the touch didn't net the same pleasure as before. What gives? Applebloom contemplated the feeling of cutting a warm, slice of pie upon pulling back one of her flanks before.

But that was only she knew her sister was down there too, watching, knowing that her place was soon to be inside the giant butt once more. Her cheeks only became sensitive in knowing the minuscule body of her sister was struggling against them. Pleasure arose from that. But simply touching them now didn't do such a thing.

Bloom kept watching her sister. She'd closed her eyes when the rest of the tongue rose out from her lips, a broad spire composed of warm and wet flesh, the surface of which the tiny mare was riding against. Applejack had been lifted from the lips, holding to the tongue like it were some pole, kissing and filling her mouth with it, biting every now again—which, surprisingly, didn't hurt... but felt really good.

This sex stuff was weird.

But the filly was set to learn it. To understand it to understand her sister. In learning this, the two could be closer, in a way that was different but, ultimately, the same as what they once had before. Her hoof ceased playing with her butt when nothing rose from that. But the feeling of a tiny hanging from her tongue stroked fires beneath her underbelly.

Applebloom brushed a hoof to her crotch, stroking the spot, finding the source to the tingly sensation. While it felt good to touch that place. It... wasn't in the touching itself where bliss derived from. Rather in was resting her eyes on the tiny, in holding her up with her tongue, in seeing how vast her body looked in comparison. It was in the stoking to all of the above that numbing heat of utter euphoria causing her inner-thighs to twitch.

But the pleasure was spastic. Never concerted and coming all over the place. Bloom sloshed the back of her into the gaping waters at moves done wrong, pain mingled with pleasure, the wrong thing done at the right place. Her teacher was clinging to her tongue as she pleasured herself. That was only half of the deal there.

“Muawha!” Applebloom tilted her head forward against, retracting her tongue while bringing her lips together, using their spongy surface to push off the clinging mare. She'd caught her on their outer read and, in inching over her own chest, bloom spat her sister out. “For an apple—ya sure taste like a pumpkin.”

Meanwhile and diminished, a twitch rocked against Applejack's hips as she laid against the fluff, so close, so burning and full and ready for release—all for the giant to spit her out before climax. Hardly could she stand on legs wobbly, set to collapse. Her pussy quivering in need of release.

She'd been so close.

“Seems like you've been enjoying yourself,” Applebloom leaned back in the tub as her body overtook miles once more, a landscape of fur and chest becoming once more. Her head in the distance once more and watching on. “But don't forget you're supposed to be doin' the same for me. I still don't have a clue on what I'm supposed to be doin'!”

Applejack coughed as her mane was slick from saliva and made into a wall. She swung her head, allowing it to clump over her neck and onto her back. She gazed at the giant face of the filly—aware of the round cheeks fully red. “And just what are you expectin' of me then?”

The filly need not answer. Not when torrents of waterfalls crashed from behind. The tiny mare turned around on the chest, gazing over the expanse to the belly—where legs rose from the depths of the ocean. Same of the land in-between. Foliage of scarlet, dampened and darkened, from being submerged.

“You already know what to do down there, don't ya, sis?” Applebloom giggled while her other hoof sloshed out from the waters. She nudged its edge exactly into the backside of the mare. Only a little push forward. But the promise of force reminded the two who bore the power now. “Why don't ya go down there now and work your stuff? Better than me forcin' ya in there again.”

Applejack stumbled forward on her own, held by hesitance, forced to work through it all the same. She peered over her shoulder from the subtle grounding of the chest to the complete pudge of the vast belly. The filly's eyes were half-lidded, her grin a drunken smile, every few seconds her tongue taking a lick at them.

Her words had inferred so much more than the words spoken. The filly obviously had little issue with parting the lips of her pussy and stuffing the mare deeply inside of her herself. She'd pushed her into the crevice of her ass with ease. Bloom didn't fret taking control.

But that's not what she craved here. Applejack reached the where the pudge beneath her hooves slimmed into the smooth padding of the filly's groin. She paused only to drink in the sight. To stare up high at the many vines of rich reds. The base of the forest parted enough that, with a little force, she could push through.

“Don't think you'll be going around this part, sis.” The resulting giggle from the giant cause the ground beneath Applejack's hooves to rumble about. She was able to ride it out with ease. Though she stepped closer to the sprawling bush of her younger sister's crotch. “I... like the idea of seeing you go through there. But for a strong mare like you—it shouldn't be an issue, right? All you have to do is walk through all my little hairs there!”

That confirmed it! Applejack had no choice but to push forward, swatting aside pesky branches of wine upon settling into the base of the towering bush. The scent was richly Applebloom. A fragrance lightly of strawberries intermixed with the richness of musk. Everything consumed the mare as she disappeared into the depths of her sister's bush. She was left nearly wondering if she would come out on the other side.

What the tiny mare contemplated during her journey through the scarlet forest, however, was confidence her sister was gaining. Her mind focused on it while her body pushed through thick strands and hooves pushed away lighter ones in the way. Her sister had commanded this. Bloom wanted it. And she didn't have any fear in demanding it either.

That meant Bloom could have taken plucked her tiny tail between her teeth, part the folds of her crotch and simply let go. But asserting her power wasn't what she desired. Rather this wasn't about the filly simply throwing the mare into her snatch.

But getting Applejack to crawl inside of her own will.

She broke through to the other side with this in mind, feeling a thick shadow pass over her once more, glancing up to see the dome of hoof patting the ceiling of the fuzzy trees. The filly was pleased as she stroked the area. The place made more sensitive by little hooves travelling through it.

“Seems like you made it to the other side, sis,” Bloom moaned the name than anything else. If saying of the word made her drunk on something related to it. Those hooves then dipped into the water on either side, swimming underneath the sea with ease, going to wrap underneath the legs and pushing against both thighs. “But now it's time you started making me feel good.”

Applejack turned to say something. The towering bush of red prevented any chance of that happening. Rather, in not wanting to risk the giant, she carried forward, careful for the slope of the crotch, spotting the start of two familiar mounds.

“Now, it's a bit harder for me to see you—but I'm gonna assume you're doing your best to make me feel good.” More drunken laughter as the monolithic body shifted within the seas, bringing dread to the little one. Applejack nearly craved to be inside the slit. It was better than going overboard. “Now, I promise not to do anything while you're there. Just gonna ride out everything you do the best I can. Kinda like what you were doin' on my tongue.”

Another moan came, low and longer in length, its pitch, threatening.

“B-But... since you're smaller now... y-you... may need to do a better job than you usually do.” Applejack came to the side of the bound slit, finding a familiar, fleshy boulder winking out from the hood. It was a nub fully exposed. “C-Cause if I don't feel you... and I'm already feeling really good myself... I-I... might send a hoof down there to help.”

Another giggle. “And you may not like having my hoof rub all over my privates. That's something you want to do all by yourself, right?”

Applejack nearly didn't consider the distant words as the protruding nub earned her gaze. Lying on her front, she edged left across the slope of the crotch. She was careful not to slip downward, for there was only one place where her actions could feel like a normal size mare doing them.

Upon reaching directly beneath the hood of the filly's clit, the tiny mare climbed toward it, coming to its underside curve. Trusting the grounding beneath her, Applejack rose onto her knees, hugging the underside of the fleshy object—much to the closing of the thighs around her.

“W-What was that!?” came the enthusiasm of the filly unaware of what was about to occur. Her thighs closed in like wobbly walls that darkened the world. Though no matter how much they closed, however, they came inches short of reaching the climbing mare. “K-Keep doin' it, sister! I-I didn't know... mhmhmmh... y-you could still do things like this!”

Maybe it was in being ordered and lodged within filly butt that the competitive side of Applejack flourished to the surface. Even though her splayed body wrapped around the spread of the boulder of a clit, she bore amusement in being able to turn the power dynamic back around, of her every shimmy upward sending tremors for the thighs in the distance behind her.

Could she take it back here? Any dread of this being her younger sister left as the power play of sex returned. The completion embedded in pleasure constantly held between her and Rainbow Dash. It was a matter of who could win despite both achieving victory by the end. But something of that element now.

To show this massive filly who the real big sister was.
