Rainbows Visit

With a swish and gust of wind, the clouds parted. The flow of air was suddenly disrupted, and at least two pegasi were spun around mid-air by the passing blur. A rainbow coloration arced across the evening sky at a blistering speed like a missile, shooting past Canterlot Castle to the much farther north Crystal Empire.

“...Furthermore, given Fluttershys… predicament following her dream with Luna, I need you to seek Cadance’s help. The hope is that, given her experience with alicorn-on-non-alicorn pregnancy, she will have more information on the situation at hand,” read Rainbow Dash aloud as she flew, making relatively short work of the trip with her manic speed.

“I still can't believe she was fucked through her dream; like her body was literally fucked through a dream! Man, magic’s weird…” This was the only response she could give, shoving the letter in her shorts pocket unceremoniously.

Rainbow Dash was a pegasus with a slim athletic build with well-defined musculature to her figure and wore tight clothing to show off her muscle tone. Her athletic endeavors spanned her entire figure, but put specific influence on her wings and legs. Who could have guessed that the fastest flyer in Equestria focused so much on her wings? Her mane, multicolored and brushed forward, ended in spiked tips and sharply contrasted her sky-blue body.

She wore a tight-fitting white tank top and black bra, barely hidden underneath it, holding her less-than-average bust tight. Her shorts did the same to her well-sculpted ass and hips, the former being a bit above average in size, and the latter much more so.

The only other noteworthy part of her toned appearance was her sleek and simple dark blue sports shoes, the only noteworthy aspect of them being her cutie mark on her heels.

The four-foot-six mare arrived at almost record pace, zooming past the guards, past the crystal heart, and not going through the front door. This was Rainbow Dash; she had to make an entrance. She flew up and spun around to knock on the princess’s window directly, zipping over to the balcony, and back and forth between a myriad of windows and tapping away with impatience.

Eventually, she landed on the balcony, finally content with waiting, at least for thirty seconds before her foot started tapping wildly. One might think, if they were to look in on the situation, that waiting here was literally killing her. Soon, impatience would overcome her just a tad further. “And here I thought nopony could sleep harder than Twilight after a reading session!”

Putting her hands to the window, she realized that her assumption that the princess was asleep was wrong. Nonetheless, looking around the room, it was as lavish as one could expect, with a needlessly large amount of space, and a gemstone aesthetic to the space, of course.

But what caught Rainbow’s eyes the most was a door on the exact opposite wall with a warm glow coming from underneath it. This piqued Rainbow’s curiosity far too much to ignore it. Pushing the window open, she zipped over to the door in an instant.

The clear sound of humming coming from inside begged for further inspection. Briefly forgetting everything about her given task to pull the door open, Rainbow felt her blue face turn redder than her rosy pink eyes. Cadence was drying off, fresh out of the shower, the towel over her face and drying her mane. This left her third leg exposed in great detail for Rainbow Dash.

The length made Rainbow look down at herself, immediately realizing the almost three feet of mare cock before her would reach ridiculously high into her chest, assuming it didn't kill her.

Cadance’s scepter was a lighter pink than the rest of her vibrantly-colored body, but not quite as much as her mane. It became steadily deeper in hue the closer to the crotch Rainbow looked. A heart was shaved into the pubic hair of the alicorn in question, as well. Rainbow had a similarly shaved forest down at her now-wet crotch, though hers was her cutiemark’s silhouette verbatim.

Rainbow would be taking in more of Cadance’s form if her eyes weren't locked into absorbing every detail of the princess’s length. Fluttershy had flushed with embarrassment whenever Rainbow had asked how large Luna was, but if she was anything like Cadance here, then the fact that Princess Luna’s seed impregnated her through dream sex wasn't seeming quite as outlandish, anymore.

The princess’s medial ring rested eight to ten inches away from the base of her cock, its veins flowing up the mast and dispersing before they wrapped themselves into her bulbous flare, roughly the width of a saucer plate. This raised several questions, such as who was the top in her and Shining Armor’s relationship, especially given that Rainbow Dash was pretty sure that flare wouldn’t even fit in her mouth, let alone Shining’s asshole.

“Um, Rainbow Dash? You know I can see you, right?”

Rainbow froze, her lips shivering as she realized she was drooling a tad bit from both ends as she looked up to meet the eyes looking down at her.

Cadence’s voice and eyes didn't seem angry; maybe a bit confused at worst. If anything, she had a chuckle to her tone as Rainbow scrambled up onto her hooves, pushing the door open and just leaning against it.

If she was quick, she could totally play this off… Yep, she had this. One-hundred percent. “I-I u-uh… uh, yep, I knew that! I was just admiring the, uh… royal jewels. Heh heh…” It was amazing how much heavier embarrassment sweat was when compared to workout sweat.

The tension in the air was cut when Cadance let out a little laugh. “I'm sorry. I'm sorry, really… But I can't take you seriously when, between your words, your eyes keep drifting down, dear. What brings you to my bathroom today, Rainbow Dash?”

Rainbow’s eyes ripped away from the beast that hung between Cadance’s knees. The five-foot-eight alicorn was imposing, even when relaxed, and her cock only made her more so. It let out a throb, slowly hardening a bit before Rainbow’s eyes and letting out a dribble of precum in the process.

Cadence turned around as she spoke, pulling some makeup out of the medicine cabinet. In the process, she let Rainbow take a good, long look at her almost cantaloupe-sized balls. They were almost as big as the alicorn’s breasts for the princesses’ sakes!

Rainbow paused for a moment before clearing her throat. “S-- I’m sorry… I was actually coming to tell you that Twilight needs your help, regarding an alicorn-on-pegasus pregnancy.”

The admission made Cadence pause putting on her makeup, but she soon continued. “Interesting… who did Twilight finally hook up with, then?” she asked aloud. “If your wandering eyes are anything to go off of, I bet she spotted you drooling over her cock and begged to be filled with it.”

Rainbow again had to pull her eyes off of Cadance’s body. It was her ass this time, which was larger than her own by about three times, with hips to match. It just looked so succulent and juicy, and a load of fun to be buried in.

“Uh… It was Fluttershy, actually… Her and Princess Luna… Do… Are you sure you’re fine with me spying on you? I was kinda stunned when I saw your…” Rainbow swallowed hard, “cock…”

Rainbow was beginning to feel the heavy weight of awkwardness from being a massive perv, staring at all of what Cadence had on display. Granted, she wasn't about to stop herself, but it just felt strange that the princess wasn't having her step out of the room or something.

“I don't mind,” wave Cadance. “I actually rather appreciate the company, what with Shining up and at work so early, I don't have many ponies to talk to.”

“Uh huh…”

“So, Luna and Fluttershy? That's a sweet pair. I never thought they’d be in the right circumstances to hit it off like that. Don't misunderstand me, they have great personalities for one another, but I just didn't see them meeting in bed.”

She rubbed her lips together to finish applying her lipstick. It generally just made all of her facial features pop out and be more properly accentuated for what royalty should be. It was a remarkably small amount of work for her, at least compared to Rarity.

“Now, if you wouldn't mind helping me, it would be a nice break for my maids.”

Cadance’s cock throbbed particularly hard at that point, turning towards Rainbow Dash as it rose and pulsed, even spurting out a few ropes of sticky precum. Each glob that splattered on the floor made Rainbow’s heart throb and her knees feel a little weak.

“Y-you mean… you want my help with that?”

Pointing at the long and thick alicorn member, a part of her felt very honored and especially vindicated that her body was desirable enough for the alicorn princess of love.

“Truth be told, I just have a thing for athletic and fit cuties that are smaller than me, but flaunt big strong personalities all the same,” Cadance cooed.

Her magic raised Rainbow Dash’s chin to look her in the eyes, pecking a kiss on her forehead and dropping her towel as she left the restroom proper. A clear sway flowed through her hips, her naked body absolutely melting Rainbow Dash’s mental defenses. The little blue mare couldn’t help looking at the princess and the trail of precum she was starting to make on the crystalline floor.

Rainbow practically ripped her clothes off, barely keeping her wings from shooting out from her back and having to calm herself down to coax them to fold down as she zipped past Cadance and into the alicorn’s bed, giving all the confirmation the princess needed.

Rainbow Dash laid back as flat as she could, the only exception being her raised leg and the hand holding it. This spread her crotch open for Cadance to view, almost biting her lip the whole way through as the alicorn princess pushed forward.

Cadance grabbed her and twisted her a bit to straddle her leg, leaving the pegasus’s hips on their side. Her magic groped Rainbow Dash’s ass cheeks, prying them open gently. The invisible force of her magic was a weightless sensation; not as tactile as, say, a pair of fingers squeezing into flesh.

She pressed her leaky flare to Rainbow's winking holes. “Which hole do you prefer, dear?” Cadance’s voice was smooth like velvet and easy on the ears, almost as much as her body was on the eyes. Her pulsing totem pole of impossible size pressed against Rainbow’s pussy, clearly showing her own preference.

Rainbow Dash gulped a little at the prospect of either hole being impaled on the length. Even as Cadance floated a bottle of lube over and lathered her shaft and tip in shiny, slick fluid, it throbbed against Rainbow’s cunt.

Dash wasn't left dry, though. Cadance’s fingers slipped from her length to dig into and lube up Rainbow’s asshole with little to no warning. With a lecherous leer, she wriggled her fingers into the blue mare’s relatively small, and certainly very tight, ponut.

“Nyghh~ Y-your choice, princess,” were the only words that croaked out of Rainbow’s mouth before a moan started to warble, then sharply jumped up an octave. This turned into a teeth-gritting, bed-clawing squeal as Cadence immediately forced her flare into Rainbow’s pussy.

Her magic held both of them steady to allow the member no chance of slipping off course on the way in, leaving it just a straight thrust deep into the sensitive rosy walls of Rainbow’s cocksocket.

Feeling her depths stretch well past what they were used to, from fingers to dildos and even a few of her fellow Wonderbolts, Rainbow let out a sharp exhale as Cadance’s flare pressed against her walls. They were stretched apart without remorse as a hard slam rammed through Rainbow’s cervix and into her womb. All of this, without Cadance’s medial ring even being near her lips.

“My, hmm… You athletic types are always such nice, tight and snug fits…” teased Cadance. “You like it fast, right?”

Rainbow looked up, but couldn't even utter a single word in response before the alicorn’s hips pulled back, dragging her flare across every sensitive stretched nerve. She had just enough time to take a breath before Cadance slammed back in like a battering ram against the far wall of Rainbow’s womb.

Rainbow’s abdomen bulged out. Cadance admired her handiwork and pulled back again a half-second later, slamming forward just as hard. A rhythmic beating began that progressively stretched out Rainbow’s uterus further up into her abdomen.

“O-oh my gosh, o-oh my gosh!! O-oahu fuck~ oh my gosh! Sweet Celestia!!” cried out Rainbow Dash, her head throwing back against the headboard as her entire body jerked up with the force of each thrust Cadance gave her. Nearly three hard slams per second rocked Rainbow’s head and body. Her wings ruffled slightly, her mane already looking a tad messy as the bulge in her torso moved further and further up with each inch deeper Cadance pushed.

Eventually, she settled her hands on Rainbow’s hips, letting her raised leg rest on her shoulder. This was not a reprieve, but rather a shift in position as the pace quickened further; almost twice as intense in no time. The only thing Rainbow could even will herself to do was clutch the sheet covers and moan her head off through rolled-back eyes and tears rolling down her cheeks.

While this felt incredibly good, it also hurt. That’s not to say that Rainbow wasn't used to pain, just not usually from the depths of her womb pushing up into her intestines and shoving her stomach aside to breach further up into her with each passing second.

Cadance’s hips could finally clap against Rainbow Dash’s cheeks. With each thrust, her balls smacked against her ass. Paired with the occasional hard spank against Rainbow’s flank, the blue pegasus felt like she was on fire.

Her guts burned with pain and pleasure, feeling the princess’s cock slamming away the red protrusion in her torso. The bulge stretched her skin and fur, going so far up her body that the bulge was slapping against her breasts with almost every thrust. Her ass stung in pain, her core was starting to feel sore and her pussy’s gaped, twitching, red lips were swollen quite a bit after the constant hammering slams that felt like an eternity.

“U-uyghh~ S-sweet fuck, you’re killing me!” was the only thing Rainbow had said in the last several minutes, though her face portrayed a much different attitude. Her eyes rolled back, eyelids fluttering as her latest orgasm rocked her body. Nobody had bothered keeping track, but Cadence hadn't cum yet in the several minutes she'd been pounding Rainbow’s insides into a more accommodating shape.

Eventually, despite panting and severely out of her gourd, Rainbow Dash felt the length in her guts suddenly pull out with a wet pop. A torrential orgasm gushed out of her gaping hole’s swollen lips, spilling all over the bed.

“W-why did you…?”

Cadance didn’t give her a response. Instead, she flipped Rainbow over onto her stomach and grabbed her by the mane and tail. Her spine bent, Rainbow’s face was mashed into the pillows and her ass raised into the air.

Cadance’s cock ground between what little ass Rainbow had for a few moments, letting Dash find her bearings and do her best to look back at the princess of love. Cadance was pressing her flare against, and then more painfully, into her asshole.

“F-uck! Ff-f ahh!~” were the only words Dash could force out, if you could even call that talking.

Cadance chuckled to herself as she pushed slowly into her fucktoy, the bulbous tip of her flare squishing into her as the pushing force made her virgin ponut spread apart.

A burning sensation shot up Rainbow’s nerves, making her grit her teeth as her nails cut into the sheets.

“Nyhmm~ You’re tighter than Shiny… I recommend you take some deep breaths, sweetie. This may be more than you can handle…”

Rainbow tried to follow the given advice, sharply inhaling and promptly crying out in painful pleasure, feeling Cadence slam her flare into her and making her entire body quiver and shake. Her wings twitched out for Cadence to grab, and the princess yanked hard with her magic, letting everyone in the palace hear Rainbow squeal in pain.

Cadance shuffled her knees closer, digging her cock several inches in and growing deeper by the second. It was mere moments before she was pushing through Rainbow’s bowels and up into her intestines, stretching them out. Her cock soon pressed against her stomach, shoving it and her poor stretched womb aside on its way through her.

If she were in a clearer state of mind, Rainbow would have thought that Cadance’s monstrous cock would just push through her stomach, into her esophagus and out the other end. Well, Cadance’s way had a few extra steps.

Her horn glowed and a portal formed at the entrance and exit of Rainbow’s intestines, right inside of both sphincters. Her cock buried itself in and stretched out Rainbow’s stomach and torso, as far up as her breasts. This left the blue pegasus with a phantom feeling of a cock in her intestines.

Rainbow’s burning mind tried to make sense of what was happening, until Cadance’s hips pulled back again. She then started jackhammering with all the force she could muster.

Several minutes of hard thrusting followed, which wasn't as big a deal for the princess, given she had sex at a minimum of once a day, though more often two or three times a day. For her, this wasn't that tiring yet, even if it was making Dash pant, with each hard thrust making her gasp and groan, moaning constantly.

“Ahh, yes, Rainbow Dash! You’re going to make such a good cum dumpster~ F-fuck… Yes! Are you ready for the biggest load you've ever felt?!”

This was the only warning Cadance gave before her nuts clenched and she slammed balls-deep into Rainbow’s ass. Her cock bent, distending out Dash’s torso just to fit every inch into her. Cum rushed through Cadance’s urethra as her cock throbbed, the globs bulging out Rainbow’s torso even further, demarcated by a clear line down the middle of her body running from her twitching clit to her collar bone.

Cadance’s cum soon erupted into Rainbow Dash, creating a bulge between her breasts that quickly went down her length into her belly, making it sag out, swelling larger by the second.

When the first gallon had filled her, Cadance pulled back, a torrent of cum gushing out over her cock, balls and the bed. She slammed in again, her balls clenching hard as another several gallons flooded into Rainbow’s guts, making it erupt not only out of her ass, but up out of her mouth and nose.

Cadance’s cum was thick and very hot, making Rainbow feel full and warm as it seeped into her. Her cum was a powerful aphrodisiac that made the crying, twitching and gasping pegasus feel as though her entire body was filled with nothing but pleasure. She came who knew how many times as the sticky fluid rushed up her esophagus. The thick, salty goo filled Dash’s sinuses, shooting out her nose and lips until the several-minute-long orgasm eventually ended.

Rainbow Dash’s belly, as big around as a beachball, squished and deformed under her. Cadance’s balls, however, weren't empty yet and there was plenty of time left until the day started.

Rainbow was given the brief reprieve, however, when Cadance stopped to record a video message spell to Twilight:

“Hey, Twily! We’ll be there later today, with Rainbow Dash in tow. Say hi, Dashie!”

Cadance pulled Rainbow by her mane into frame, showing off her itty-bitty titties in comparison to the princess’s own. The blue pegasus in question, a twitching mess still coughing up seed, just gave a half-hearted groan of “H-hey,” before the message ended and the fun began again.
