Slowly Growing into Her Kingdom

~ I ~

Bragging and Tagging

The stroll across Sweet Apple Acres had been a slow one, an awkward one, filled with nibbling at her lips, slowing the swaying of her hips, and doing her best to not look back. Rainbow was behind her, and literally, a step from being actually behind her.

“So when we snuck out during the Gala, you were actually trying to take some book... that makes you grow a little bigger.” Twilight could feel the gaze lurking on her ass, the attentive notice of her hefty cheeks rubbing against each other, slipping in and out and, try as she might, despite the injection of nervousness that welled in her veins—her thighs tingled at the attention. “Not sure why the princesses would lock something so cool away. Or why it only has to apply to princesses.”

“I can't say why the princesses locked the books away, but I do know that only an alicorn has the power and energy to use them.” A curving stream cut through the land ahead, a small stone bridge leading to the other side—closer to the Everfree. Twilight came to a stop. Should they go deeper, or should they—

“Whoa—nuh!”

Twilight shivered at once and clenched on the spot. Her eyes widened while her cheeks burned scarlet. The slipping of her cheeks was pleasurable while she walked, but now, she felt a tight blue muzzle shove itself into the crack of her ass, slipping in deeper by the second.

“Yaow! Mmhmm!” The voice and groaned came muffled from behind her, through her, the vibrations of Rainbow's voice, making her flanks quiver from their touching proximity. “W-Why did you stop walking? And let me out!”

Twilight froze for a second. That pleasuring shifting of another mare caught by something like her ass made her eyelids slide closer together, that tingling in her thighs coursing closer to her crotch. She'd clench her cheeks upon feeling the impact, and the grip of her flanks on Rainbow's snout was firm enough to keep her there.

No matter how much Rainbow tried, wiggling and shifting and pushing, she couldn't escape the confines of Twilight's butt. She was so small too! Her body came up to the top of Twilight's thighs and, when her face became caught in Twilight's cheeks, it was within the underside of the tight and heavy purple ass—where the dough of her purple flanks was the warmest.

Twilight lost herself for a second. How would it feel to have more of her slipped in back there? She lifted her butt slightly in a mock attempt to realize what was happening, hearing the fluttering of wings as Rainbow was lifted slightly off the ground by something like her rump.

“Ohmigosh! Rainbow Dash!” Twilight let her flanks relax in the next second, feeling the muzzle slip out from her crack. The hollowness struck at once. The feeling of her big ass having nothing caught between it, the only sensation of one hefty cheek jiggling into another, both desperate missing something in the middle. Don't think like that. It isn't right. “I am so so sorry about that!”

“Ugh! What did you stop for anyway?” Rainbow was sitting on her own rump while rubbing a hoof against her snout—its sight of it coloured in a faint pink. Had she perhaps... enjoyed that? She did compliment Twilight's backside. “Not that I don't mind getting a face-full of purple ass, but you gotta warn a girl a few seconds before, ya know?”

“R-Rainbow!”

“Aw! What are you complaining about? I'm the one that walked into your rump.” Rainbow stood with a shake of her head, the blush on her cheeks remaining the same. “And I still don't get why you're so uptight about all of this. So what if you stole some sacred book or whatever? It's not like you're doing it to do anything bad.”

Rainbow started to smile.

“Don't you say it,” Twilight said—a second too late.

“Unless you're smothering my muzzle in your butt.”

“Rainbow!”

“Sorry.” Rainbow chuckled. “Had to go for it.”

Twilight only dropped to her rump and lowered her head in response. She wasn't sure what to say or what to do. Her mind, much less her mind had been a paradoxical mix of sensations, producing feelings that she knew weren't quite right. But the more she tried to fight them, the more that itching, the heated pulsated grew from her crotch. Loins burning. Limbs Aching. Everything begging for a little bit more.

“Seriously, though.” Rainbow's voice floated from somewhere to her side and, when Twilight raised her head, felt prismatic strands of the smaller mare's tail flicking against her cheek. It touched her. The act something special. Teasing. Pleasing. Her crotch was heating again. “How about you and I go and talk over by that tree over there? Nopony ever goes out that far this late. We can be all alone if you like.”

It'd been a long time since the last time didn't have to take charge, where she could follow the lead of the smaller mare, and while she did so, she couldn't help but find her eyes on the same spot where she'd been so protective of.

Rainbow's rump shifted before her eyes and, even though Twilight did her best to avert her gaze, turning her eyes left and right whenever she had been staring for a second too long—they were always drawn back to the small, tight, blue backside.

It wasn't the biggest of rumps. It wasn't the smallest of ones either. There wasn't a lot to the blue butt before her—but that made it cuter in the way. That there was only so much do it, a quantity so small that made Twilight want to hug and hold and claim it all.

It was tight, alright. Tight blue cheeks shifting left and right, in and out, a delicate slipping of fuzzy blue fur warm to the eyes, supple to the gaze, arousing to the place Twilight tried desperately to ignore.

“You can look at my ass as much as you like,” Rainbow said while keeping her head straight, a smile reaching back to the corner of her mouth. “Don't think you have to worry about walking into it from all the way up there.”

“I... wasn't looking.”

“Sure, you weren't.”

Twilight didn't try to fight that thought. There didn't seem to be a point in trying to do such a thing. Instead, they carried over the slope of the stone bridge while the light lapping of water from below filled their ears.

More than once, Twilight had to fight walking a bit quicker. If she wanted to, she could easily walk past and over Rainbow, having the smaller mare walk in-between her legs and underneath her barrel with relative ease.

It was a strange turn on. The scratching of the itch deep within Twilight's crotch. Knowing another mare, one as brash and doing as Rainbow Dash could walk her tallest directly underneath her—that at any moment, her long, purple legs could buckle and her barrel would come crashing on top of Rainbow, covering and smothering her entire body with a little room to spare.

And not only that. But the teasing would be cute. Oh, yes. Twilight did her best not to close her eyes as the mental pictures played through her mind. She was heavier now—not fat except in all the right places—due to the longer limbs, larger barrel, bigger frame. All that soft weight would come crashing down on Rainbow and, no matter how hard she struggled, shifting and rocking, she would be pinned underneath the larger mare.

No, no, no! You knock that out right now. Twilight breathed in through her mouth as stone transitioned to grass against her hoof. By the time she looked forward again, the taut muscles underneath Rainbow's flanks were gone from her gaze. A glance up confirmed Rainbow was already up against the tree, standing on her hind legs with her back against the bark, with a field behind her covered with many more trees. What you did before was already too much. You can't lose yourself to... feeling good.

“Enjoy the show I threw for you?” Rainbow tilted her chin up. “Cheer you up a bit? Give you something to think about?”

Twilight shook her head. “You know I didn't mean for something like that to happen. I... just wasn't sure where we should go next.”

“I know.” Rainbow went to lower her head while Twilight approached her, but as the mare was a few feet away, quickly gave up on that idea. Even when she stood up on her hind legs with her back to the tree, her gaze came only to the chin on Twilight. “You're not the kind of mare to be catching faces between your flanks. Not that it was a bad time.”

Twilight rolled her eyes. It felt strange to be face to face with Rainbow again. It made her feel like the older sister to a filly, almost. Right now, Rainbow was close to the size of one, with how short her frame was. “You're going to keep teasing me about that, aren't you?”

“You know I don't mean anything by it.” Rainbow shook her head. “And you know the girls are worried about you. I'm worried about you.” She waved out a foreleg. “Ditching us without saying anything wasn't a cool move.”

Twilight looked to the ground, her hooves on the ground looking far away—like she was staring at them from the second story of a building. She hadn't grown much, and yet, she was starting to feel that way about things. “I know, but I just... didn't want the girls to find out about this.”

“Nopony is perfect, Twilight.” Something touched her on the chin, lifting it slowly to a pair of ruby eyes staring back at her. Within their small reflection, Twilight saw herself, too big for the tiny frame. “With maybe the exception for me of course. You got into a little mischief with a book you weren't supposed to read. Big deal.”

“But it is a big deal,” Twilight fired back with wounded words, “when it's making me grow!”

“It's making you slowly grow—something you were already doing once you got the wings.” Rainbow pulled the hoof away, not with a smirk but a smile. “Not going to lie and say being even more in your shadow is the greatest feeling in the world. But it does give me one heck of a mare to look up to.”

Twilight smiled at the words, but also closed her eyes at them, knowing what to expect next. “Are you going to make another dig at my butt?”

“If I was towing something like that around, I would be checking in all the compliments I could.” Rainbow leaned to the left to get a better look at it—only for a purple foreleg to press itself against her chin, pulling her back. “It's a pretty impressive set back there. First hoof experience and all that. I don't know why you keep thinking it's a bad thing.”

Twilight dropped her hoof onto the grass, feeling the sweeping of evening wind swept across her back, lift strands of her mane, and doing nothing to ease her dread. Those sensations grew again. Rainbow slid down the bark of the tree by an inch, the slight quiver shaking her hind legs unable to expend the effort to keep herself tall—something Twilight did effortlessly.

“Because it's something that's not natural, Rainbow Dash.” Twilight knew that wasn't the truth; she also knew that wasn't a lie either. “Nopony isn't supposed to change like the way I have. It isn't right.”

Rainbow rolled her eyes. “Right! Because growing and getting a pair of wings out of thin air is natural.”

“It isn't like that!” Twilight stepped toward the mare, blanketing half of her body within her shadow. Her ruby eyes had fallen to the height of her chin, forcing Rainbow to tilt her head back slightly. “It's through a magical progression and completion that made me into an alicorn! Why do you think my body grew then? To become big enough to store all that power.”

Rainbow blinked. “But isn't that what's happening now?”

Twilight also blinked. “W-What?”

“Think about it.” Rainbow came off the tree, her hooves clopping against the ground with her head tilted all the way back. Her head came at Twilight's chest, the tufts of purple fluff there something she could easily be smothered with. “Casting that spell makes you bigger, right? Your horn looks longer by the looks of it. That must kick off some extra damage.”

Twilight's eyes flew up to the tapering length of her horn, the images of Cadance's horn flashing in her mind. “That was a rather complex spell to be cast so easily...”

“See? The spell is totally just making you bigger so you can contain more of that magical power stuff.” Was Rainbow onto something here? Twilight confusion and inner-conflict worsened while she thought about it more. It didn't help that Rainbow Dash was so tiny. Twilight almost felt like she could step on the smaller mare. “Just think of yourself as a vessel for awesomeness. The bigger you get, the more you can hold, and the more butt-kicking you can do when you need it.”

Rainbow came to the side of her right foreleg, gazing up from its side like one staring up from the bottom of a towering column. Twilight nibbled on her bottom lip. Fighting the urge to wrap a foreleg around Rainbow's neck and bring her in for a tight hug grew harder by the second.

“And don't get me wrong.” Rainbow slipped into the gap between the pillars of Twilight's legs, coming inches beneath the sky of the taut, purple belly above. The soft slope of the ceiling, that right amount of pudge, nothing but a comfortable and delicious sight to the one below. “Not only is getting superpowers from a super spell to do some super butt-kicking super noble and all that—but I won't be letting any other mare tower over me like this... unless I really liked her... and thought... y'know... she was incredibly sexy.”

Twilight stiffened into stillness and kept that way out of sheer fear. Beneath her was not quite the mare of her dreams but the one she thought of most when staring out to the clouds. Brave and bold and able to confess something so fragile with ease.

And the power from it all... that faint sense of lust dripping, foaming around the both of them. Twilight shook her head as she kept herself propped up high on her long legs. Rainbow was still below her. The height of her limbs tall enough to tuck another beneath her; the length of her barrel more than able to cover the whole of Rainbow's frame.

That knowledge intoxicated the brain.

“S-So, you like this, then?” She might as well have been talking to none since nopony was around her except for the field. The mare who made her voice stumbled blocked and tucked away by her own body. Like her growth allowed her to speak freely, her own size keeping away the one that made her so nervous. “Being beneath me, then? A-Actually having a mare taller than you?”

“H-Hey hey! Don't get the wrong idea just yet.” The voice floated out from somewhere between her forelegs. They were joined by a muzzle brushing against the soft slope of her tummy. “More often than not, I'm the one on top. But there's... something exhilarating about so easily being over matched by your body alone.”

Two mares, alone together, separated but touching.

“This spell... it does more than grow me, Rainbow.” Twilight blinked her eyes while the quickening of her heart ushered out a harsh breath. This felt like a crime to share—but keeping it to herself had more than cracked her heart. “It makes me feel good. Like, really really good! And I want nothing more than to have more... but something about it just feels wrong!”

“Tons of things look wrong if you keep glaring at them,” Rainbow counted from beneath her, the edge of her blue muzzle popping from between Twilight's legs. She titillated her head, looking shyly up at the taller mare. “But maybe you need someone to try it out with? We're both alone. You've got a thing for me, and I've already spent some time behind and below you.”

Twilight shook her head with a smile. “You're really are a cheeky one, Rainbow.”

“Helping my friends is half of my element,” Rainbow said, “and getting to help myself while I'm at it proves just why I'm the best of us all! Hehehe. Except for you, of course, since you're towering over me and all that.”

“Sometimes, I love the way you lose your way with words.”

“You gonna cast that spell and have some fun or what?”

Twilight sighed. It still felt wrong to go through with what felt like a crime—but nothing could stop her now. Not when her body yearned for it, and the small mare tucked between her forelegs begged for it. She could only cast it a few times anyway. Trying something new was always encouraged by Princess Celestia before.

So why should this be any different?

Twilight closed her eyes and surged her horn with power. Multiple colours swirling and merging and becoming a splash of one that pulsed through her. The effect was intense despite lasting only a few seconds. Her bones aching as her legs grew longer, the length of her barrel curving as it expanded.

And the concentration on her rump. That's what made Twilight roll her head back, eyes closing tighter and tongue moving across her lips. Her sensitive flanks swelling with a subtle wobble, a soft weight then turning hefty. The way they ballooned in perfection, broadening their curve, the pleasantly swelling sensation always drawing a wiggle from her hips.

“Whoa now...” Rainbow's voice came speechless as she lowered to the ground, rolling on her back to watch the spectacle. Her entire frame cast in the shadow of the larger mare, feeling ever smaller despite no difference to her own size. “N-Never thought I'd ever find growing pains attractive. But from the looks of it. It's not painful in the slightest, is it?”

Twilight had stumbled out of the glow, seconds after it had finished, the size of her body caught in the sunlight. She was perfect evermore for the inches tacked on to every inch of her. It wasn't that one part or place had become bigger—but all had done so in an identical fashion.

And Twilight returned to the world in a daze. Blissful airs kept within her head as the start of the high was only starting to rise. That tingly feeling tickled beneath her skin and other areas of softness. So many days repressing that goodness only for it to build.

The small blue mare laid on the ground in a way that left her open, her lithe frame ever so tiny. Twilight gasped her next breath as they came in low panting. Hotter and hotter. It was too easy, with this mare caught in her shadow, to drop herself upon her, covering every inch of her frame, of course, with nothing by the length and width of her barrel.

“E-Eh? Twilight?” Rainbow giggled to herself on raising onto an elbow, a hot blush emerging to her blue cheeks. “Kinda looking at me like a snack here. Everything good inside there?”

Twilight didn't bother with a response as she simply licked her lips. She strode toward the other mare in silence, secretly enjoying how not only was Rainbow washed within her shadow, but that it now became darker the closer she approached.

And without any words, she stomped her hooves on either side of Rainbow's head, one second after the other, each impact making Rainbow flick to them in panic. She writhed her body closer together, a tail catching itself between her forelegs, something which she stroked upon gazing up.

Up into the sky, where the muzzle of Twilight loomed, staring down at her, the sudden shift of control terribly arousing to them both. Twilight buckled her legs with a grin, the weight of her flanks slamming down on the girl, both of them filling and spanning over the fuzzy blue crotch.

“Ooof!” Rainbow arched up from the sudden weight pinning her torso to the ground—not enough to crush or harm her—only for her muzzle to become caught by something. Lips. Long, soft and slim. “Mmhmm?”

Twilight had arched her forelegs to lower her muzzle, catching Rainbow into a kiss, a direction planned from the start. She moaned at the feeling of something soft and warm now meshing against her. Countless years gone without the romantic connection to another—controlled now by a virgin heart.

Rainbow didn't struggle beneath her, although her frame kept wiggling underneath her weight, trying to get comfortable or something akin. It felt cute. Nice even. Knowing this mare had to move and struggle beneath her weight—something which she was nearly unaware of how much of an impact it had.

It helped both girls melted into the kiss. Rainbow soothed after a few seconds, her shifting dying to little wiggles, all of which reminded Twilight of how much bigger she was, of all everything led in her direction. All she knew was that she was hot and making out with Rainbow was making her warmer.

And she craved evermore.

Twilight started slow. While exhaling sharply through her snout, the roll of her hips covered the whole expanse of fuzzy belly beneath her flanks. She delighted in the flicked beneath her, the other not trying to escape, but rather, milking out more of that sensation.

“Mmhmm... y-you... like that, don't you?” Twilight broke their kiss with those words. She pulled inches away, panting. “Having a bigger mare pin you to the ground like this? K-Knowing you can't get away.”

Rainbow wiggled from underneath the thighs of the bottom-heavy girl—only for Twilight to smirk and then sit down, harder. Groans escaped her. Her signature smirk still upon her. “Not like I'm the only one gettin' off to this. Hey, Twi?”

“I suppose so.” Twilight continued rocking her hips, smothering more of the girl beneath her, delighting in something as low as rubbing her rump over the belly and crotch of the other girl. This was warming her more in a specific place. “I think you may have opened up something you shouldn't have, Dashie.”

“Have you forgotten who you're dealing with here?” Rainbow seemed comfortable with having her whole body grinded a little too easily, those purple hips rising and falling across her. Paths of blue fuzz made slick. “You may be bigger now, but don't you forget, this is still the same, more awesome than awesome itself, Rainbow Dash here.”

“That so? Little mare like you is able to do anything?”

“Getting a little cocky now? Love this t-transformation you've got going on.” Rainbow put on a brave face, but beneath it, anxiety brewed in nervous shudders. Being bossed around by a big sexy mare had been one of her kinks. And Twilight fit the persona much more than she'd been expecting. “You may be a mountain now—but don't think I can't climb you with ease.”

Twilight only arched her head back and moaned, leaning more mass onto the smaller mare, getting her fill with dominating her body against Rainbow. Heat sauntered from her crotch with slick strands of her tail catching in-between her flanks.

“Think your small little body is able to scale me now? Certainly the brave explorer, aren't you?” Twilight smiled upon falling back, cushioning her fall with the extending of her wings, spreading all of her legs apart. The bed of her barrel, chest and belly, fully exposed. Her horn glowed a subtle violet—its aura thicker and dense despite no added effort. “But let's see how your body reacts to being placed on me, shall we?”

Rainbow hardly had sat up to drink in free oxygen until the whole of her frame floated into the air. She tumbled in the bubble and witness her destination below. Twilight looked so large lying on the ground, easily twice the size of her, close to Luna and half of Celestia.

And she had just agreed to climb that.

Rainbow was spinning her hooves by the time she was falling, the landing beyond soft, although the ground dipped in a wave, one that wiggled away, slowly rising around her again. The purple flooring was unstable, but, after pressing her forehooves against the chest of the being, she was able to lift herself a bit easier.

All she saw was Twilight's muzzle in the distance. She sat up slightly, looking down at her from a foot above. “Having trouble with my body there, Rainbow? And here I thought you were a good climber.”

“You're attractive when you're confident.” Rainbow then chuckled. Even though she another mare's body spanned around her body like a bed, she continued to speak, despite being upon another living thing. “Just a shame you're going to lose it once I scale you.”

“Pfft! Says the climber who's falling.”

“F-Falling?”

Rainbow wasn't sure what to make of that when, from either side, the two soft, slender pillars of purple came down upon her. They settled on her shoulders, each big enough to cover them whole, their strength immense.

“Y-You cheat!” Rainbow wiggled against the hooves, although there was nothing she could do. Afar and above, Twilight only watched, giggling drunkenly to herself. She wasn't even giving it her all! While Rainbow struggled against a consistent fraction of force. “Push me down, a-and I'll... always get back up!”

“Missing my body even before you're off it? Who would have thought my new form would be so loved!” Twilight laughed to herself in a way that was strange—even for her. Her eyes drifted to somewhere else while she pushed Rainbow from her chest to all the way down the slope of her taut tummy. “Mhmmhm. Why was I even worried in the first place? Everypony admired Celestia for her stature, don't they? Now why would things be different with me?”

Rainbow wanted to voice something but felt her hind legs slip of the curve of the purple crotch. Her flanks were pushed to the grass while her chest and forelegs kept atop the belly. She gazed up to see the hooves leaving her shoulders—only for the plushness of thighs to come striking from either side.

“What's this? It would appear our little explorer has found a cave!” Twilight said in a tell-tale voice, one silly and fake, far more much like her. Her cheeks set alight with a blush, beads of sweat streaming down her muzzle. “Why d-don't you rest there for a bit, Rainbow? You must be tired! Y'know, i-if you treat that cave right—maybe you'll have a bigger mountain to explore once you come out!”

Rainbow wasn't in much of a place to fight that as the thighs locked around her neck, diving her face closer to the exposed crotch of the larger mare. The scent twitched her snout at once. Heated wisps of lavender with a spice of musk filling the undertones. This wasn't her first meal of this sort—but never had a smell been so strong.

Truly it hooked her. The richness of the warm texture palpable to be tasted on the tongue. Subtle weight tacked to the air. Rainbow closed her eyes and inhaled heavily, devouring the most potent and most personal smell of Twilight's Sparkle sex. It filled her lungs, wreaked her body, and drove for the single urge to only capture more of its taste.

Even if that meant burying her muzzle deeply into Twilight's crotch, like a pig at the trough, hungry to an animistic degree for pussy. Utterly humiliating—especially to a girl like Rainbow—and yet, she dived in, seeking her humbling reward.

Twilight shivered in her spine from feeling the muzzle of the other girl dive into her crotch, a place previously undiscovered by any before, now a face completely covering it. It drove a trickling of warm honey from her flower at the thought alone. The entirety of Rainbow's muzzle was needed to cover the expanse as something as once small as her crotch.

But she gazed down the lane of her chest and belly to the pegasus locked against her bottom, muzzle before the place where her heat escaped, no doubt drinking in the scent of her cunt. It bathed her face, and yet, she kept there.

Was she going to do it? All doubt was wiped out when Rainbow's muzzle leaned in, granting a tentative lick to the folds of Twilight's sex. It was like water dripping onto a stove and proceeding to sizzle. Her thighs tightened together at the explosion of sensation—one she desperately strove more for.

And Rainbow Dash was willing to grant her that wish. Her muzzle lodge in the parting between her folds, her tongue continued to lick, collecting the bittersweet slickness coating the place—faster than more lubrication could settle in.

Twilight writhed. Attempts of strength lost to the evoking of her weakness. The most her crotch had experienced were trembling, inexperienced hooves, rubbing shallow circles over her tummy and dipping an edge of her hoof barely an inch into her cunt.

But now?

She was having another mare stuck into the untended place, tufts of pubic mane long and down the sides, clean but locking in her scent. The tightness of Rainbow's muzzle pushed her folds apart, each limp against the sides of her snout, which then buried itself into her cunny.

There was a kick in her left leg, evoking shame. It twitched every other second while the tongue lapping behind her folds was starting to get lower and lower. It almost felt mechanical, not at all unpleasant, but rather like a servant forced to commit.

And for whatever reason, that got Twilight off even more.

“T-That's a good girl... y-you're... mmhmm... r-r-really good at this!” Twilight wasn't aware her hips were rolling back and forth until feeling the effect they had on Rainbow. Her snout bumped into something small and round and terribly blissful. “A-Ack! T-There! Do it more there! Please!”

Rainbow kept her muzzle locked in place, but her eyes travelled up the expanse of Twilight's underbody, direct eye-contact. There was a shine to them, confidence brewing her seemingly passive expression. Like it was her way of letting Twilight know she'd found one over her.

Which Twilight didn't mind in the slightest.

Well, so long of course that she continued to eat out her cunt like a good little filly.

“Like that! More! Please Rainbow, e-e-enough teasing... g-give me more!”

That was enough for Rainbow to win their subtle battle, allowing her lips to press around the fuzzy, purple ball, taking it within the warmth of her mouth. There, it was moist, a difference easily felt by the numb dense with nerves. It loosened it, setting it on edge, so high for contact that it shivered in its absence.

Then she attacked. Her lips closed upon it at once, nestling it upon the two lanes of softness, suckling on the nub with all the delicacy it demanded. Extra pressure came only in the licks, flicks after flicks, earning quiver after quiver—under a slow, broad one, then struck.

“GAH!” Twilight arched her towering form into the air, nearly flying into the air were it not for the mass of her ass set upon the grass. That, and the tiny pegasus that weighed her crotch to the ground. She assaulted her clit with long licks and the suckling of plush lips—the skin-bursting euphoriashaking her body into a state of nervous never ever inflicted by anxiety. “Nnngnnh! Nnagh! Y-You're... you're so cheeky!”

Rainbow grinned while keeping with her work. Below her chin, vines of thin white leaked from the base of Twilight's cunt, dripping onto the round swell of her flanks, the subtle boiling within setting upon the softness and skin of her tush. Pleasant fires needed to held back and put out.

Twilight gazed over at the mare with a grin. With the back of her hindleg already resting on Rainbow's neck, she pushed down upon it, forcing Rainbow—who gasped—to the bottom of her cunt. She forced her head low, enjoying the sight of the plump blue bottom swaying in the air, left and right, the loose strands of prismatic accentuating the show.

“W-Well? What are you waiting for, Rainbow?” Twilight was panting when the words came out of her, sweat dampening her fur. Her perfume of richly musk dominating the air. There wasn't a trace of the other mare upon her snout at all. “You created this mess, a-and now, you're going to clean it up!”

Rainbow was poised before the entrance of her cunny, though it was only her exhales that entered the clenching, steamy depths. Something had caught her. But whatever was going through her head could be saved for when Twilight wasn't in an agony of arousal.

“Unless you're the kind to l-leave another mare hanging!” Twilight continued with a bitter taste plaguing her tongue. It was mere teasing and egging on. Mares in steamy books did it all the time. “Maybe I am too large of a challenge for you anyways? Don't worry about it then. I can tend to it myself, and you can watch if you—“

That'd done the trick.

Rainbow's muzzle dove in seconds before the thighs tightly kept to the sides of her head, most of her snout past the parted folds, her tongue entering the hole that was supposed to be tiny. It must have been strange for her to take on a pussy so large and yet so proportional. The fact that such a place was bigger than certain areas on Rainbow.

But the pleasure was intense. Twilight was finally able to lay back on the grass while her pussy was assaulted by every possibility of perfection possible. She'd never felt more control in her life. Holding someone like Dash between her thighs and locked against her crotch, her muzzle and tongue deep within her cunt, that slender tongue tending to every inch of her dripping walls, all of which squeezed when they pleased upon the intruder.

It still wasn't enough. Even while Twilight rubbed hooves from her chest down to her belly, tending to the expenses that equally needed care, she soon realized that her body was becoming too big even for herself to care rightly for. As should be the case. Within her was a slowly growing perfection.

And perfection, due to how rare it existed, always needed to be praised.

Twilight unfurled the greatness of her wings and set its dips upon her belly, the sensitive places rubbing together, fur standing up from the contact. Her forehooves kept to her chest, drawing better circles over the tuft of purple fuzz as if directing the direction of the fires beneath.

And her hips. They kept arching, beating against Rainbow's face, diving into Rainbow's muzzle. Her eyes were closed as her face kept buried in the squishy portion of Twilight's groin. Moans. Low but long. The swaying of her cyan hips delightful to watch. Their little jiggle a tingly delight.

“Nnnghmm... R-Rainbow?” Twilight rolled her long neck against the grass, the rest of her body doing the same, unable to repress the gooey goodness building within her. The peak of the heat ready to explore as sweat cooled her coat enough to reveal the bliss of it all. “You may want to be careful. T-Think I'm—“

Rainbow had a strange way of taking revenge.

All of this had been more than strange for her but, when in the company of Twilight Sparkle, things sorta became that way. There always seemed to be a logic to it; all the larger mare could easily explain once all was said and done.

But Rainbow's mind had focused on only one thing.

Pleasing this lavender mountain of a mare.

That's why she didn't mind the smacking of pure crotch against her face, of the tufts of pubic mane reeking of sex whipping against the sides of her muzzle or, much more immediate, how deep her tongue was being dragged into the desperate snatch.

But she didn't stop her efforts, but instead, redoubled them. Licking and lapping and tweaking her muzzled up and down to work against the sensitivity of the folds themselves. The way the larger mare curved against the ground spoke of the effect she had. How doing such small actions could make the ground of purple start to quake.

Of course, however, in pleasing such a mare, she now also needed to take the hit for it.

Twilight outright arched herself forward from the added efforts, her colossal frame washing over her own. Rainbow stopped swaying her rump upon feeling not only thighs but a forehoof pressing into the back of her head.

Rainbow's eyes flitted up to see the larger mare leaning over her own body, bringing a foreleg over the arch of her hind, the hoof pressing down into the back of her mane. With the slightest of pressure she pushed down. Where the plushness of the thighs had been locking but vague in the pressing of their desired direction—that single hoof didn't struggle with any of the above.

She fought. Bucking her head back and wiggling her body around. But all of it... it was pointless! The thighs absorbed her movement, and the hoof only pressed her harder and deeper into Twilight's pussy. All while her hips buckled and fucked her muzzle in.

Rainbow wanted to cry and scream, to call foul and fly away, and despite her image, bravery and bravo... the plit-plat dripping from between her hind legs had given herself away. Being forced and pushed around by a bossy mare, all with trying her best to undo those effects, had made her dripping wet.

How could she not be? Being held by the weakest and sexiest parts of a mare, forced to pleasure her pussy with the whole of her face, kept and beaten there by a crotch alone, made to serve in such a humiliation fashion. It was rare to be on bottom. Even more so to be pinned there as well.

Rainbow closed her eyes as she continued to eat delicious violet carpet. Munching and munching almost not for her own sake but rather to serve. Her own hooves struggled beneath her under-body, inching further and further against the soft slope of her blue belly, trying to reach that inflamed place between her legs.

“Mmhmm? O-Oh. Is my subject getting off to this?” Twilight muttered the words like they were delicious treats creamy with alcohol. “Worshipping my pussy the way it deserves. Neglected for far too long! But a—mmhmm—princess always rewards good subjects.”

Was this foreplay? Rainbow's mind was drunk on musk to consider if the character being played was for real or for pleasure. Either way, it got her off. Scary enough, if it was the former rather than the latter... it seemed to please her even more.

But before anything could be pondered, something long and broad prodded at her hole, lifting the curtain of her tail and settling on the base of her vulva. Thick and full, soft but hard, a precision aided with feathers granting aid to a tunnel clenching for any sort of substance.

And when that wingtip finally entered the tightness of her cunt, slowly but filling out upon arrival, she lost it. Rainbow didn't give a single fuck as those long and delicate feathers continue brushing across her throbbing clit while filling and flicking her from the outside out.

She'd be happy to serve only Twilight's pussy for life if to retain this level of satisfaction.

Twilight grinned upon having the mare. She was lost now, Rainbow, that was, to the pleasure around her. Why shouldn't she lose herself to the greatness of her own humiliation? Her pussy needed to be teased by a wing while a crotch bucked into her face and a hoof pressed her against it upon every thrust.

This was why Twilight needed to become a princess. All the good she could bring to the world! She panted, and her head swayed back and forth in the air, humping the muzzle of the other girl, watching how she ate and ate without any complaint. If she could reduce the great Rainbow Dash to nothing more than a mere sex toy due to the increase of her size and power and pleasure—then the same could be made for those around her.

The... spell!

Twilight Sparkle knew it was beyond cheeky to do, especially with Rainbow where she was now—but such a thing ceased to be a concern when the other was comfortable with her place in life. Without any drop to the thrust of her hips, Twilight closed her eyes and charged the spell again, sooner than any time ever before—but this overriding intake of pleasure had granted her the fuel to cast again.

The tip of her horn shimmered, although this time, not only had more colour joined the swirl of the casting—but the magical layer dipped and washed in the fluidity of the sea. Despite its lazier appearance, something different had come from it. A hurricane of power contained within the sphere of her horn.

“Are you still with me down there, Rainbow? Because I think you're going to wanna listen to this bit.” Twilight gained power as strength flushed through her system. The spell cast and blast through her. The tingly delight of growing limbs thrusting her crotch ever harder and longer. “You're going to get to experience me grow! And you're going to feel smaller and weaker while it happens.”

Rainbow's eyes were closed as she more or less laid in the canyon between Twilight's legs. Space opened up around her, although the legs keeping her became broader, and she much smaller in-between them.

Twilight couldn't get enough. It wasn't enough to see her body grow for how normal it then seemed to her, but rather, how Rainbow's body went from lazily leaning on her broad bottom to now being able to lie upon it.

Much more was her cunt, now more spacious without losing an inch of tightness, taking more of Rainbow into it. Her body caught and made small by something like her bottom. Shrinking and shrinking while parts of Twilight's body grew into lands.

Finally, that was enough to do the trick. Twilight couldn't help herself as the next thrust became violent. She kept her hips arched into the air while pinning Rainbow's muzzle in place, flicking her pussy quickly while the dam of her cunt then broke to a stream of gooey rewards.

Splash after splash of heated honey doused across the muzzle of Rainbow, creamy white sticking to short furs of blue, keeping there and appearing clean. Thicker goblets leaked like drool while the aroma of the innermost parts of Twilight baked the area. Once more, her scent lingered over all, able to make even herself drunk upon it.

Love for perfection, regardless of its form, wasn't narcissistic.

By the time they were done, both were tuckered out, each with their own reasons, yet left in the same kind of state. It was a bit of a surprise that, once the thighs had spread from Rainbow's muzzle, and the legs around her gone wide—she kept in place.

The wing within her cunt stroking its last strike, causing the smaller mare to shrivel and then finish, her personal juices striking against the grass. Wetting herself like that in public. Coming nearly to command without any shame. Losing herself for a moment, letting herself go, and briefly returning from it once she had come back.

Without word or command, and despite all that occurred, Rainbow Dash walked across the side of the larger mare, who had rolled the same, watching her while panting. She approached the broad chest of purple tuft and, snuggling herself against it much like a kitten, then collapsed beneath it.

Twilight smiled. She laid some of her body onto the mare, blanketing her body with heat and softness, tucking her close to a place where her heart beat. It soothed the tuckered out lover, the slow breathing pushing out against her chest.

They laid together and, while Twilight wrapped her forehooves against the smaller mare, pulling her ever closer, everything had been doused in a sleepy-time perfection. Although something, fundamentally, had changed.

Something Rainbow Dash summarized in a single feeling.

Although she loved the way how Twilight blanketed over body, she wished the larger mare wasn't hugging her so tightly and, no matter how much she shifted or wiggled, there wasn't anything she could do about it.

Not that she minded all that much.
