Main Story

Cloudsdale sets itself apart from many other areas of Equestria. Unlike most towns or cities, it has an excellent view of the surrounding landscape, peering even over the great Canterlot Royal Castle and the adjoining city. With a perspective high in the clouds produced there; not from a mountain top, of course as any Pegasus will tell you. Politically, it differed little but sought a necessity to elongate the lifespan of ancient arts and crafts made industrial; but without dropping the social flair.

For years it has been studied by Unicorns; that the Pegasi are without magic but somehow capable of sustaining a life in clouds by providing them with a pseudo solid nature, a magic only they possessed. Perhaps it was just having wings that gave them this power, but that seems so logically lacklustre and deficient. Although the natural anatomy of these creatures was intriguing, as they featured lighter bone marrow and a resinous coating through their fur giving them a biological streamlining.

After your; “chat;” with Twilight, she insisted that for your own development and current predicament, that you visit Cloudsdale and call on a one “Rainbow Dash.” From what you’ve heard she enjoys the athletic life and isn’t afraid to back down from a challenge.

"Great, just what I need; to be disparaged by a pretentious athlete while she mocks my little knowing of her world. Why can’t I stay with twilight and “study” ponies there?"

You think to yourself.

Twilight had given you a cloud walking spell, nothing to ostentatious; like wings or something, you’re not quite sure, but it will allow you to stay there for at least 24 hours.

"Remember Anon; it only works for 24 hours. So you’ll need to be back down by tomorrow. Unless you want to fall 6000 feet Hehe. And also if you get lost following the map, stay out of Galloping gorge, you could get stuck there. And beware of timber wolves."

"Geez, is anything safe in this; well utopia."

You make your way north, and out of Ponyvile, into some corn fields when you see Canterlot, situated high on a mountain face, proud and prominent.

"Hmm, impressive. Looks nice; will have to drop by there on the way back."

Bringing your gaze round from the white walls of Canterlot, you catch a glimpse of a cluster of cumulus clouds that seem slightly out of place. Not to mention the fact that they have rainbows pouring in a widely dispersed arrangement on to the ground below, riddling the landscape in an excellent spectrum of vibrant colour.

"Must be it then."

Making your way up was going to be tricky, as there seemed to be no stairs or; elevator at the base when you arrived.

"I guess twilight, wanted to see if I’m able to figure it out for myself then."

A hint of sarcasm piercing your voice. While looking around with bewilderment, and some questionable aggravation, you hear a sound above you.

"Hey there, what you up to mister!"

You stand erect, and look up peering into a low lying cloud. A cyan figure with the barmiest looking; somehow perfectly segregated rainbow coloured hair you will probably ever see.

"Is that a mullet, is this the 70’s."
"Can I help you, who; er, whatever you are. Cause you look like your staring at the ground from up here Haha."
"I’m a human, and I do understand that I’m new here. I might be quite frightening but you have to..."
"Bah, frightening. You’re about as scary as Fluttershy’s pet animals."
"(Who’s Fluttershy?)"

You think it must be another friend of Twilight’s.

"Sorry I’m trying to find a way into Cloudsdale, and I have no idea how to do that."
"Well, Pegasi can only get up there, and besides, you wouldn’t be able to trot there. You don’t have any wings!"
"(Fan-fucking-tastic.) Could you help me get up to the city then.. Sorry what’s your name?"
"My name? How could you not know my name? I’m one of the ace flyers for the Wonderbolts, and the best flyer in Ponyville, Rainbow Dash!"

She yells at you. Well that makes things a lot simpler. At least I’ve found Rainbow.

"Right Ok, well Rainbow, how do I get up to you then? Your friend twilight, has given me a spell to let me walk on clouds, so all I need to do is get up there."

Rainbow comes down from the cloud she is perched on and you can’t help but notice the surprisingly titillating sight in front of you. All your prerequisite thoughts on deciding her inevitable body shape immediately disappeared when the well endowed mare displayed the effect an accelerated puberty must have given her.

"(Geez, that thigh gap is, ... monstrous. She could probably swallow moons with that.)"

Her exceptionally curved hips gave her thighs, that challenged the jeans she wore; tightly hugging the luxurious mounds with an ethereal understatement. Just a foot or two above disproportionate, but from her waistline the top half of her frame seemed fairly normal for a sportsperson, slender and toned with a sharp neckline and curved tinted cheeks. Then you notice the wings. All of a sudden you realise that you’re not saying anything, ... let the ‘Prickles, Blurts, Headlaugh’ begin.

"Helllloooooo!"

Cocking her head and brow while waving a hand abruptly over your face. You burst into words comprehending that you weren’t saying anything and just wishing that she didn’t notice the goggling of her form.

"Yes, Hi, Hello, I am, err, Anon Y. Mous, and err, it’s good to see you Rainbow, yes, yes of course it is .... err."

You then explode into a casual laugh rolling your head to make everything look ok. Dash just stares, sweat dripping down your face.
She has a stern look and scans you lackadaisically strolling around your mistakably rigid figure. Walking forward and round, her thigh gap was opening and closing with a rather pudgy motion, her hips swaying causing your eyes to drift with them in tandem like a clock weight. She eventually turns and smiles.

"Right, ok well Hi Anon. Why do you want up to Cloudsdale? You don’t look like somepony who would enjoy weather fabrication; or well flying? And how do you know twilight?"

You explain to her that you found your way here by falling in the night, as much as you had felt like you fell out of your bed. All of a sudden there were trees and wolves made of shrubbery, which was weird. Running away, Twilight found you near the edge of the forest and took you in for the night, and in the morning said it would be good to explore Equestria by visiting Cloudsdale.

She ponders for a second, surreptitiously nodding and smirking.

"So Anon, you want up into Cloudsdale huh? Well Mr, you can come up with me, but clench your legs when I... lift you up.’
"(Believe me, they are clenched.)"

You’ve managed to identify that the wings on her back gives her species a name that suits with excellent Greek intent. That is probably why they live in clouds, like the birds almost.

She tightens a hand around the hand strap of the rucksack you are wearing and flares her wings to their full reach, ready for take-off. And with that and little effort, you are hoisted off the ground.

"Holy crap, ARRRGGGHHH!"

You start to scream as the air gets very thin very quickly and the ground gets smaller developing an insane vertigo ridden thought in the back of your head. Rainbow looks back and smirks shouting.

"Scream if you wanna go faster ya scaredy cat!"
With great dread you peer up giving her a frightened expression. She laughs looking up and pumping a fist forward in a super-woman-esque manner hastening her pace, rocketing directly up. You close your eyes and before you know it, the air is, no longer rushing past your ears?
Tentatively opening your eyes, you examine your surroundings.

"Oh; my; GOD!"

The sight in front of you instils a deep and overwhelming awe; that encompasses your every sense. The previous thoughts in determining the etymology of the Pegasi has been doubtlessly confirmed by the sheer architecture of the surrounding marble-white buildings, sedentary on the poofy pale clouds. Each building had Greek like inspiration including Ionic Columns and Simas that quivered slightly in the wind, verifying the cloud material of construction. Waterfalls cascaded enormous volumes of epicene-coloured and viscous rainbow. Pegasi flew around with informal regimented intent going to jobs and shops. Some wore hard hats and Lab coats; carrying clipboards and barometers. From what you gathered previously in preliminary readings at Twilights library, Cloudsdale makes weather, tying in with the whole rainbow, pouring, thing.
Rainbow Dash interrupts your gazing.

"Here I’ll show you round."

“Pause”

Wandering around with Rainbow, she introduces you to various other mares and stallions out and about, being busy, as well as the variety of locations. The town square, the cloudseum and young flyers school. She is more than averagely bubbly about seeing the Wonderbolts academy.

"I’m currently training here to become a full member of the ace team here; it’s been a lifelong passion of mine."
She gets nervously giggly when a certain blazing crested orange mare passes you two.

"(Must be the top ace.)"

You begin to notice that in comparison to the Earth ponies on the ground, the Pegasi have a different structure, (as if Rainbow was any exception). The mares are slightly petite but also like Rainbow’s features; not disproportionately, but larger thighs and smaller frames.

"And this is the rainbow factory."

She says proudly. An immense structure again made out of the same malleable material, clouds. Featuring tall chimneys and floor-ceiling windows, like, you guess any other plant.

"I work here, we make all the clouds used throughout the rest of Equestria. Many ponies complain when we have to give them rain clouds, but we always explain that there needs to be water in order for crops to grow."

"(Wow imagine controlling the weather back home.)"

Eventually, with the day passing, you arrive at Rainbow’s home just in the south part of the town. A humble abode, tinted a slight purple with the water logged clouds laden above. She moves forward in front of you to unlock the door. Her assets in full view of your desperately frisky eyes. The turning motion of her key shifts the supple and copious derriere, delicately budging a days’ long lust in your trousers. The both of you enter, and you distract yourself with the scenery of a tidy home. Everything, as you expected, is made from clouds, which sitting down on a couch made of the material felt better than any settee ever before. In the kitchen you hear Rainbow bustling about moving mugs and tins you think, none sooner coming into the room carrying tankards of; Cider? Accepting the colloquial vessel you sip gingerly met with a distinct and superb taste as she sits spreading her buttocks on a velveted chair pushing the arms ever slightly.

"So, how do you like Cloudsdale, enough awesomeness for yah."

She gives you a gleeful expression, and you return the favour.

"Aww you kidding, it’s so amazing! The place is teaming with life and it just defies my interpretation of science."

She laughs, cheering her glass and you raise with her both of you taking a big swig.

“Prepare yourself reader...”

Still focused on her, you look up and down, the chair availing no unfamiliarity to you. Admiring the squatness of her sitting position, she notices and looks down for a second.

"Don’t think I haven’t noticed you checking me out there Anon!"

You are brought crashing back to ... well Equestria... and give a scarlet blush.

"Err, I well. Yes I was"

You mumble.
She giggles slightly, and stands moving over to the couch you sitting on and seats herself on the other pillow, the couch somewhat upending.
A sultry gaze passes over her, one eye brow cocked up and taking another sip of cider. You take yours with nervous disposition and trying to diffuse the situation

"You are very forward aren’t you"
"Well yes, I get very competitive about; who I choose."
"Choose what?"
"To play with."

The cider hits just a little to the left and you cough suddenly, establishing the amazing cliché of abrupt surprise. Spluttering you begin to gibber, thrashing your words with child like stutters.

She leans forward her plush behind rising from the sofa and her face comes close to yours. She lifts the timber tankard out of your hand and places them both on a fuzzy coffee table.

"Do you know what the amazing thing is about the liquid of a rainbow?"
You give a stifled shake of the head not unlocking your gaze.

She whispers in your ear,
"It’s an excellent aphrodisiac!"

You swallow hard realising that the tankards disguised the colour of the rainbow liquids sat in the bottom.

"Do you enjoy new experiences Anon, cause I can get very experimental."
"I am always open to new things."
"That’s awesome."

Closer still.

"And I have seen you staring at my behind, I’m guessing you like a round rump."
"Never enough."
"Well Mr. Unfortunate, you’ll have to foreplay until I tell you that you can play with it. But don’t worry you can’t ignore something so big for so long."

And suddenly, she presses forward closing her eyes and pouting her lips. Instinctually you pucker your own lips and feel a simple moistness swathe and interlock. Testing each other’s mouths, with light boxing sounds you tilt your head to get easier access and she coos flippantly and sighs. The tongues are set free and you begin to roll around hers tasting her delicate pallet, a mixing of cider, blueberries and hay oddly enough? She explores your mouth reeling in your teeth and toying with your tongue distracting it with waylay wrestling.

This continues for a time you cannot even count, lost in bewildered beauty and tentative tonsil tennis. Your hands trail south embracing Rainbow, pulling her up and closer to your body. She pulls herself in bringing her back upright and pushing her wide hips out, the jeans material stretching and straining. This whole time the yearn in your lower body continues to grow uncontrollably and the sound of straining fabric draws out a desire that your body refuses to quench. You begin to follow your original path, tracing her spine with your exploring hands ever closer to the plump bounty below. She stops pecking and draws her hand from your own back and brings it round clasping your wrist and announcing.

"Uh, uh, uh. Wait until I tell you too."
"Sorry, the tension is killing me."

She steals a smooch.

"Lets’ relieve some of that then."

Rainbow stands from the couch and pulls you round to the front, kneeling down, her legs clamping together and pushing cushiony goodness around them. She wraps a hand around your belt and caresses a swelling package located just below. You let out a sigh pulling your head back and she giggles. Opening the belt and fly, she slithers her hand in and pulls forth a girth that immediately begins to pulse a crimson colour.

"That’s so awesome."

She clenches your member with a caring compassion tenderly stroking, flaring the head and fondling your testicles.

"Oh my god!"

The dirty smirk on Rainbow’s face says it all for you and with wordless proposition, she lulls her tongue and with lust filled eyes, she sweeps the base all the way to the tip with exaggerated deliberation. Your mind explodes with unprofound and ill reputable thought, as the dampness hugs your shaft causing further litres of blood to drill into the still extending length. Rainbow continues to slowly go the length up and down your shaft and lets out moans and purrs each time she turns. Eventually she stops.

"Are you done with your service sir?"

You look forward gazing into her eyes. Pulling upright you embrace her once more and kiss her. You stand up taking her with you. No more pretense.

"Shall we..."

She looks lovingly and; starting to walk out of the room she takes your hand leading you away and up the stairs. Her swaying of her hips was definitely more exaggerated, the banister intermittently being nudged by her width. In the bedroom, you take her in your arms, grabbing the plush plot first. She gasps surprised, which is stifled by your next kiss. Rubbing her behind you move the glorious butt flesh about jiggling and caressing. She giggles effeminately and continues to moan into your mouth as she steals small pecks and smacks. Her wings begin to flare; slightly opening to measure her building hunger for more.

"Wow, you taste awesome."

She puts her hands back and places them on your own, pushing them further into the pillow-like goodness, stroking the bubbly tissue and pushing it about tensing the denim. You break the kiss and opening her eyes; Rainbow throws a sultry gaze and nuzzles her nose on your own. Her command is wordless, but lucid.

As you crouch down, she steps back a few paces, balancing her thighs against the bed and creping them against a fluidic brume bed. Lifting yourself up on your knees you look up at her with a final smile and as she returns it with confirmation to proceed, you draw your hands across her ankles and winding round feeling her nimble fibula and tibia, buried in broad plump suet. She sighs, lulling her tongue and raising her chin. You give a delicate squeeze, educing a moan most audible, revealing the foreplay was effective. Squeezing some more you pull in, pushing your face into her pelvis feeling your cheeks abrading her thick midriff. The pining begins to intensify as Rainbow nibbles her bottom lip looking down as you fondle your nose round her inviting Eden, now groping her fat thighs with tentative fingers, irregularly polishing her plot. Short drawn breaths are now emanating from both of your lips, and as much as you can feel the excitement growing inside Rainbow, a distinct smell and taste tingles your nose and mouth. A strange mixture of sports sweat, blueberries and a hazardous guess at pre-cum.

"Why; are you teasing me."
"You want me to stop?"

You say with a confused tone. She grabs you violently and hauls your face close

"Uh, no mister, I want it now, just be a bit more radical."
"Radical?"
"But be cool..."

Oh really? Well if it’s a dive she wants, then let’s plunge.

Adding pressure, you topple her to the bed, upending her legs and flattening her back against the quilt. Lunging for her jeans she throws her head and arms back:

"Oh yes, oh yes!"

And as you un-button the waist, the jeans breath freedom popping open with a burst of loose skin. Your member has drastically stiffened as you look upon her exposed lower tummy and a pair of pink panties peeking over the top of her fly. She lightly writhes as you clamber over her cautiously placing hands at her sides. You lean down near her lower solar plexus and inhaling deeply you take her fly in your teeth and looking up, tug gently. She begins to pant as you pull down gripping the fly and releasing more fuzzy fur and stretchy panties. Stopping at the bottom, you reach a hand up and push the length of your index finger smoothly along a vague outline. She giggles lightly and then moans with lust purpose. As you lift your finger away, you drape your tongue and trail it over her panties, bridging the slit and accentuating the Munro of her lower stomach. Flipping the muscle, you glide back down, wetting her even more and taking in the beginnings of pleasurable excitement. She moans with bliss, groping her chest mounds and tugging at her t-shirt with strife. You repeat the motion gliding up and down, adding a gentle flick near the top and bottom causing her to tense each time with anticipation.

"Omigosh, omigosh, oh-my-gosh!"

She yells loudly bringing a hand down and pushing the back of your head deeper, until you can feel the velvety vulva. You pause and push your tongue in sensing a button-like stiffness which you eagerly push. She screams a passion that rings around the bedroom, verifying the success of your motion.

After what seemed like 10 minutes, you lift your head up and away, the taste of her nethers stinging your senses and gripping your throbbing desire. She lifts her head up and staring at you with covetous libido pulls her jeans off her feet immediately resolving with her panties, while raising one leg and tilting to hide her sex for a big reveal. As you gaze down at her, the angle of vision only highlights her thick curvy body. Her bubble butt and colossal thighs.

"You ready, cause I can’t wait for much longer."
"Don’t worry. I’ve been dying to scale those mountains all day."
"This is going to be so awesome!"

Dash rolls over, bearing all. You shudder slightly and pose as a rabbit caught in bliss filled headlights. She gestures a finger drawing you in and clamber back on top of her flaunting your member for her. She smiles and with split second athletic reactions pushes you to one side, and with a tumbling motion and a few gasping, you end up on your back.

"My turn first buster."

Barking with a commanding voice. You go along with the horse-play, and watch carefully as she pushes her sopping broad labia down ever closer to its mark. The head of your shaft twitches in anticipation as it finally breaks through. The soft flesh feels amazing and as entry transpires and Rainbow gasps and sighs closing her eyes and looking to the stars. Slowly and consistently, she continues to force down amassing more of your stiff dick, and gathering more volume in deepening sighs. Reaching the base, your eyes lock while tilting your heads and you both know how the other is feeling. You buck your hips upwards, thrusting a little deeper inside pulling forth a long drawn out pant from Dash. She responds knowing that you are both ready to start the nights round of high jinks, and begins to slowly oscillate with a magnitude sufficient in tenderly increasing the desire up and down the length of your baby maker. You both are now responding to each other’s cries of craving, moaning to let loose the pent-up aching. Rainbow attempts to suppress the sounds by leaning forward and connecting your lips, whining a ravenous drive home as you respond in kind, while lifting her flank up to get a better range and allowing you access with your own hands. Placing one hand upon each hemi sphere, you grope lightly and push the fat in large circles.

"ah, oh, ah, oh"

She obviously enjoys it, teasing her flesh around her lips appears to be effective. You realise that despite their size you could push all of the paunchy skin in her butt and thighs to air her clenched rectum. As she continues to peck your lips making tentative smacking sounds, you lightly push one finger into her second hole; and all of a sudden she stops kissing and screams straight into your face and then immediately shifts to your pillow realizing she may have burst your eardrums. She stops the pounding and pants heavily into the pillow next to your face. Her wings have now begun to flap furiously, cooling each of your bodies, their hardness still apparent.

"Why’d you stop?"

You question her and she turns to you.

"Sorry I got a little lost."

She says still panting. Getting an idea, you lift her up and to one side pulling her around to assume the doggy-style position, while pushing her shoulders gently into the mattress. You are up on your knees with a straight back, poised over her as she presents her butt, with her arched back pulling the flesh around, making her thighs even bigger. You pull your hand back along from her shoulders and trace the base of her wings. The feathers near the end begin to twitch as you continue to trace along her humerus. She sighs enjoying the sensation of having her wings massaged. You lift your hands away, Dash still panting, and bracing your cock with one hand and steadying yourself with the other on her rump; you push the head very slowly into her anal cavity. She squeals into the covers gripping the duvet and wrapping into her fists. Her breathing quickens as you push as slowly as before into the hole, her yells amplifying and giving in to a primitive instinct. You start to thrust, slapping your testicles against her slit while hammering her depths with violent passion feeling her pressurize the muscles working with and against you to maximise both of your enjoyment. Sensing that your climax was approaching, you pull her body up and kiss her neck and she returns, tilting her own head back permitting more love-making. Your thrusts have not slowed, but if anything have quickened and she bloody loves it, as she pants with a mouth wide open and a smile that curled at the edges, you realize your goal.

Your seed bursts from your balls, heat tracing the length of your cock until its set free into Dash’s squishiness, so much so that dribbles have broken the dermis seal between yourself and her mounds. Her eyes cross and dart from the top of her head to your own as she steals a kiss. She pulls herself gently away parting her butt with her hands and with a straw-like slurp, is set free, more juice ebbing onto the bed. Looking down you realise that Dash has hit her climax as well, as she lightly rubs her cliterous with two fingers and then begins to suck them, making her way to the bathroom. She comes back in a towel and throws you a spare.

"We’ve made a mess of the bed, wanna “cuddle” some more and the sofa?"
"I’d like that very much."

You stand up wrapping the towel around you to shield from the light cold air in the surroundings. You make your way over to her as she stands with amorous intent, raising a leg around the door skirting. With a final embrace and long and lusty peck. You both make your way downstairs.
