Coco Pummeled

The frantic clip-clop of Rarity's hooves filled the corners of Carousel Boutique. Between each half-finished dress she zipped, making quick adjustments, re-adjustments, and re-re-re-adjustments.

Something had to give. Either her willpower, ability to stay awake, or Coco's unannounced absence. At times like these, with the days to her next fashion drop ticking closer and closer, she needed help. Yet, the little earth mare she'd rescued from the clutches of that dastardly Suri was nowhere to be seen.

It was meant to be a temporary arrangement - a helping hoof lended while she sorted out this year's Spring line. Rarity paid for the train ticket and covered Coco's stay at the nearby hotel, and for the first few weeks everything went as smooth as the silks she sewed.

Then, poof! One morning, Coco simply hadn't shown up.

Rarity, polite and generous as ever, waited.

And waited.

...And waited.

When lunch passed by with no sign of the mare, Rarity resolved to do something about it. Coco's assistance was in sore demand, but she feared for the mare's well-being above all else.

The hotel seemed the first obvious place to check. She called, and yet - nothing. Coco hadn't checked out, let alone left the building - according to them, anyway. She wasn't in her room when they looked for her, either. Rarity had gone there herself to confirm, and returned to her Boutique disappointed and frightened.

That was three days ago now.

Afraid for her dear assistant - dear in more ways than a mere friend - and desperate for the expert aid she required, she had her friends search the town. All the while, she worked with a manic pace, hoping to Celestia that Coco was alright.

A soft, melodic rap on the door made her jump. She swore as her needle tore through the fabric, blinked away the ache in her eyes, and set her tools of the trade to the side.

"Hello?" she called, mortified by the croak in her voice. "Is anyone-"

Nopony was there.

She took a step forward. Her right hoof made contact with something, and without thinking she plucked it up with her magic.

Beyond its rectangular shape, she couldn't make out any finer details through the thick bubblewrap casing. Easing the material apart, she walked back inside and slid the package free.

It was a video tape. Slapped on the front, somepony placed a plain white label and wrote across it 'Coconuts' in bold black print.

Now what in Equestria could that mean? Coconuts? How silly.

The tape didn't feel very silly though. She couldn't begin to place her horn to why, but it gave off an odd, almost skeezy aura. She disregarded it for the time being, placing it aside while returning to the laborious artistic process.

Not until the crickets arrived did she pause for rest. Dinner consisted of re-heated pasta and a cheeky few glasses of red wine - something to keep her tanks fuelled for a few hours more.

By that point she'd forgotten the tape's existence entirely. At least that was before spotting it on her table.

In her tiredness, curiosity, and the desire to push away her obligations for a teensy bit longer, she picked it up. She hadn't the slightest clue what to possibly expect from its contents, but popped it in her television nonetheless.

The screen was dark for a good long while. She began to worry the tape malfunctioned or her TV had, before noticing the blinking red dot on the upper right hoof corner.

Light came through. Peeks of it crept in, exposing a more definitive shape and color.

Purplish-pink. Two large, ovoid spheres. Contained in a larger, distinctly... fleshy package.

Rarity's brain processed the sight before she could acknowledge it. She wanted to deny it, but the moist smears on the footage, the crease between those orbs, and the two large cheeks flanking either side of them was undeniable.

Obscured by the view of her voluptuous ass, the sneering, punchable face of Suri Polomare leered at her through the camera.

"Heeeeey Rarity," Suri said, in a voice just as grating as she remembered. With her plot stuck in the air, tail flagged, she waggled her hips and made her cheeks clap, balls jostle, and cock sway. Rarity could see but an inch of it, but from that peek and its girth she knew the monstrous proportions. Though, the orange-sized testicles jumping and pendulously swanging could have told her all she needed to know. "Long time no see. I hope you've been doing well."

She laugh-snorted, placing a hoof to her wrinkled snout. "No, actually, that's a lie. You ruined my career. Or tried to! Turns out the right words, some cash, and some fat maredick gets you pretty far in the fashion industry, hmhm."

Rarity was livid. Jaw clenched so tight it might snap, she was prepared to rip that tape from her television and smash it to bits. She got within hoof's reach before-

"Now I'm sure you're tempted to yank this tape out, smash it apart, and hunt me down for bloodsport, mkay. But I wouldn't recommend doing that! Not if you wanna know where your precious little assistant's gone."

Her hoof stopped, trembled. Eyes wide, lungs breathless, she placed her hoof back to the ground.

"See, I'm back in the industry, mkay? But it's just not the same without my dear, sweet, precious Coco. Tchyeah sure, she takes forever to get me my coffee, but have you seen that ass? And that cock, mmfuck." Suri licked her lips, and Rarity saw the veins of her cock pulse. Rarity's face flushed, and she felt her own sex ache. She had indeed seen both, and very much enjoyed the view - among other things. "So I've decided I'm taking her back."

Suri stepped aside, revealing a well-lit hotel room. On the bed was Coco with her face down, ass up, blindfolded and gagged.

Most insulting was what she wore - Lavender lace lingerie hugged her tight, chased with red ribbons and trimming. All of it from the stockings to the choker and corset Rarity had made personally for the mare, for her own use or when Rarity so generously offered Coco those 'employment benefits'. Now, she was wearing it for Suri? Suri of all ponies!

From her position and the camera's angle, Rarity saw Coco's flanks on full display - huge ponut, seat-filling booty, and the longest, thickest, veiniest, most godfuck huge meatpole Rarity had ever witnessed in her lecherous life. If Coco wasn't a bottom anal slut she would have tried taking it, but just as likely it would have split her open. Something so large it brushed past the forelegs might as well have been useless when it came to actual penetrative sex. Dear fucking Celestia though, did she love to play with that thing.

The clothing extended to Coco's naughtier bits as well. Keeping her wrecking ball nut-factories nestled neatly between her thighs was a matching ball bra. On her cock, a lovely sleeve, woven with special fabrics and enchanted so Coco could use it like a condom.

Through the fabric, Rarity saw Coco's excitement. Each errant, earthshaking twitch made the dark spot at her urethra spread and distend. She'd been left there to drool for long enough a small sag had formed, filled with what Rarity knew was the most potent, virile she-cum in all of Equestria and likely beyond.

"Isn't she such a treat to look at? Lovely little outfit you made for her by the way. Too bad you'll never be able to truly satisfy her. Sure, strap-ons are an okay enough substitute, but nothing beats the real thing." Grinning, Suri paced back into view. Lifting a hindleg she exposed the full length of her monster maremeat. While unable to compete with Coco's colossal tool, Suri's still sent a flutter of fear and arousal straight to her cunny. "And she's such a good, obedient bitch too. Even after all this time away, her body knows its place. And that's with my dick inside of her, not some cheap plastic toy, mkay."

To illustrate her point, Suri knocked her head towards the bound mare. Coco's nostrils flared, and it became clear she was taking in deep, soulful whiffs of Suri's no doubt potent musky aroma. At the same time her barge-like bitchbreaker jumped and pulsed more eagerly, shots of pre-seed pouring forth into her pseudo-condom cocksock.

But the most obvious sign of enthusiasm came from her asshole. Large, puffy, only able to hide behind her tail and too thick for her cheeks to conceal, her squishy pony donut winked incessantly. The sphincter clinched not with rhythm like even a mare's pussy might, but rapidly like a thundering heartbeat. Rarity knew from experience that when Coco got that way, nothing short of earth pony strength could pull anything out.

The smirk on Suri's face made Rarity's blood boil. Yet she could only watch. The worst part was the ache between her legs, insistent as it was persistent. She should have been outraged, horrified. And she was.

But heavens above, was she also horny.

"I think I've made my point well enough by now, mhm, so let's get that gag out and hear what the strumpet's got to say for herself."

Rounding to Coco's front, Suri first undid the blindfold, then the gag. Coco's baby blues went wide as saucers at the ramrod flare staring her right in the face, and as though on instinct her jaw dropped and tongue fell out.

She shook her head quickly after, shutting her eyes as a full-body shudder wracked her legs - all five of them. Her hefty flanks tremored in response, the subtle clap of her cheeks barely audible through the recording equipment.

"I-I-I'm sorry Rarity. I-I didn't want to, b-but-"

In a flash, Suri wheeled around and mashed her ass against Coco's face. Snout directly inside the star, right above the sweaty taint, and lips kissing her sack, Coco's eyes snapped open. The look in them went hazy, and a second quake rocked her from head to hoof followed by a squeaking moan.

"I just...: Mwah, slurp, sclorp. "Can't-" Schlurp, slarp. "F-fight it." Mwah, mwah, mwah, schlurp, schlirrrp, sssssccluuuurrp!

By the time Suri peeled her plump periwinkle plot away, Coco's face had gone red, and a series of stringy, spitty bridges connected her chin to Suri's flexing ring. Her taint and scrotum, likewise, shone and glistened, strands swaying idly in the hot hotel air. Rarity found herself almost hypnotized watching them move, the most low-hanging fuckropes breaking off and plopping onto the otherwise pristine white sheeets.

Suppressing an undesired whimper, Rarity pressed her velvety thighs flat. She could just so easily imagine being underneath those two dickmares, opening her mouth and accepting every drop of obscene, vile fuckgrool that dribbled out. It would fall into her greedy, waiting maw. Taint her tastebuds with foul degeneracy. Then she'd swallow, letting it slide down her throat and corrupt every inch of her on the inside on its way down, forever marking and changing her as nothing more than a useless jizzdump for horrifically hung she-mares-

The obnoxious, sneering voice of that bitch Suri snapped Rarity from her trance. For once, she was thankful for its grating edge.

"Good girl, Coco. What a shame your new 'employer'," Suri spat. "Doesn't have the right fruits to satisfy her assistant."

All Coco could manage was a pitiful whimper. Nevertheless, she gave Suri's asshole a dainty, loving peck when Suri brought it back in. Rarity swore, through the fuzzy video feed, that Coco's pupils turned to hearts.

"Now how's about we get you ready, hm? Give Little Miss Pompous a good show. Maybe she'll learn something from watching how shemales do shemales and she won't be quite as much of a pathetic, dickless cuck."

Once more trotting to the opposite end, Suri put added emphasis on her stride. Like those of a sensual dancer's Her hips swung back and forth, side to side, keeping Rarity's gaze locked on her bubble butt and all the other naughty bits that went along with it.

Rarity heard the mare's hoofsteps much as she did the moist, nasty slaps of her nutfactories and the plip-plap pitter patter of potent pre-slop onto the carpeted floor. Hearing the sounds, seeing the sights was one thing. Rarity struggled to imagine what it would be like to be there, especially with the smell, no doubt feral, primal, and brimming with deep-seated virility designed to entice fertile equine pussies like her own. Certainly, through visuals and audio alone, Rarity struggled to keep from teasing her own moist, supple folds. The only thing that kept her from doing so was the sheer principle of defiance.

On reaching the right bedside, Suri climped upon it proper. Briefly she stood above Coco before hunkering down, both their turgid masts twitching and sputtering out their sticky sperm-fluids.

Lower, lower she craned herself until her ass stuck high in the air, muzzle mere inches from the musky depths of Coco's wringing asshole. Rarity first saw Suri's nostrils flare, pulling in the unbridled stink of dickmare musk, followed by her tongue slipping out and drooling unbidden.

Then, with her eyes shut, she sealed her lips around the broad girth of Coco's ponut, sucking upon it lewdly as though it were a delicious lollipop. She continued like that for some moments, filling the air with the most gruesome, sloppy sounds of wetness and juice. It came out the speakers of Rarity's television muffled, faintly underlined by static, which seemed only to heighten the raw, uncut and pornographic nature of what she was watching. All that it missed was some cheesy disc track and the feature would truly be complete.

That, and an alabaster-furred, purple-maned mareslut to guzzle their dripping cocksweat.

When the twisted act concluded, Suri's lips parted from Coco's backdoor with a near deafening pop. One long, thick bridge of saliva connected the two hungry maws, til an errant flex of Coco's hole broke it. It fell, and proceeded to drape across the immense, dark cream length of her laid flat shaft with absolute perfect precision.

Rarity laughed, quietly. In a sick, deeply perverse way, it was almost akin to art.

She would know, having made the very cocksleeve Coco wore - among other private collections.

If Rarity believed that to be the end, the next second proved her grievously mistaken. Without a word Suri dove back in head first, pushing her snout into the now slick, shiny ring of Coco's entrance. Tongue slithered out, and Rarity watched as the pink muscle disappeared into the dank, dark depths. Suckling, schlorping and moaning, Rarity was left to guess on any number of twists and turns that tongue was making. She got to see a few it made though, as it dipped or hooked inside, spreading the ring horizontal or vertical until it was less shaped like a circle and more a zero.

With a final, shuddering breath, Suri retreated. A mixture of spit and Coco's sweat coated her mouth, stained shades darker. It only took a heartbeat and breath before Suri regained her composure, and the old cocksure sneer Rarity loved to hate. Suri had every reason to grin, because beyond the shudders and sounds of rapture she'd plucked so freely from Coco's lips, if anything was sure in that room it would be their cocks.

"One more thing before we proceed, my dear, sweet, precious Coco~" Pulling open the nightstand drawer, Suri produced a tall plastic bottle. "Because my expert oral skills can only do so much."

As she said the words, she turned an eye towards the camera and winked.

"I'll get you all nice and slicked up. Betcha like the sound of that, don'tcha? I know you do, I can see your hips and asshole squirming from here, don't deny it. You fucking love getting your ass filled, whether it's with some fake-ass lube or strap-on." Showing teeth, Suri leaned down and bit Coco's ear. The earth mare wailed, wriggling, and several audible splurts of pre further soaked her dicksleeve. "But you and I know you prefer the real deal. Meaty, pulsing marecock and rich, creamy spooge. Say it. Say my dick's better than her fake, plastic wannabes."

Coco whimpered. "N-no. I can't. I won't," she whispered, squeaking in tone.

Snarling, Suri clamped on Coco's neck. The response was immediate, ripping a high-pitched squeal of pleasure from Coco's throat, and a shot of pre so powerful it punched through the fabric.

"Yes! I love your cock and cum the most. Mnnnh." Whining, she wriggled, unable to control her fidgeting rump. "Fuck me hard! I need a real dick in my pussy! Please!"

"Please what?" Suri growled.

Rarity hoped for a retraction. A denial. Even a pause or stutter.

Instead, Coco blurted out a single, devastating word, hesitation the furthest thought from her mind.

"Mistress!"

"Good girl."

Biting Coco's neck a second time, she returned her attention to the prize. Uncapping the bottle, tipping it over, she stuck it right inside the waiting pucker and squeeeeezed. A length of time far longer than Rarity would perceive to be necessary passed before she yanked the bottle free. Half the lubricant had gone, and the second the seal broke a messy, noisy gush of clear fuckfluid erupted out like a jet. It splattered somewhere offscreen, on Suri's dick, the sheets, last dribbling lazily into the crease of Coco's balls where it could pool into some sort of rank, raunchy reservoir.

At last, capping the bottle, tossed aside, Suri was ready to fuck. She positioned herself above the writhing bundle that was Coco Pommel, who at that point shamelessly wagged her double-wide donk in anticipation and sent the cream-colored cheeks clapping and bouncing. Suri's meaty she-shaft poised to plunder her booty, but held still for drawn-out breaths. Each time it twitched the force would send the oversized spear smacking into her belly, making the balls jostle before settling back down to its idly oozing, throbbing state.

No warnings were given. No sentences spoke. Instead, the wait drew on as Coco's feverish, desperate state further devolved. When by the point she'd grown so restless as to try looking back - in spite of the blindfold - and open her mouth to speak?

Suri slammed home.

"Nyaaaaaahhhh!"

In a loud, wide-mouthed shriek, Coco made a sound somewhere approximate a neigh. Her balls spat out wads of milky gunk, and her spread sphincter clenched erratically.

Suri, meanwhile, grunted - sheathed every rich and pulsating inch of shemale fuckmeat inside the furthest reaches of Coco's premium cockpocket. As she bottomed out her own low-hung fruit swung forth, smacking into the larger twin orbs attached to Coco.

"Mmmm, fuck yeah. It's been waaaay too long since I got to have a piece of you. You were always my favorite fuck."

Coco said nothing. Her head had fallen to the bed, cheek flush with it and mouth open, tongue flopped out, drooling. She might have fooled a pony for dead, were it not for literally everything else, and bury the mention of her rapid breaths and panting moans. Rarity couldn't see her eyes, but she could imagine all manner of idiot expressions contorting her face.

Not bothering with any more fanfare, Suri seemed as eager as her pet to get the show on the road. She no longer, as her hips began to piston, spared a glance or barb towards the camera. Rarity had for her lost reason to acknowledge. What mattered was the shivering, slobbering mess beneath her - the one with the cutest face and the most fear-inducing fucktool.

A fucktool, no less, reduced to a subservient spunkpipe. No holes would be shattered by that beast. No minds would be broken. No decent, innocent mare's sense of innocence corrupted. Coco proved, without the faintest shadow of a doubt, it didn't matter how big your dick was.

If you had a goliath cuntbuster between your legs, but not the attitude to use it?

You were as good as a fleshlight.

To Suri, at least.

Or, in Rarity's case, a good dildo for practicing BJs.

Soon, Suri's back half became a blur. Her heavy, thudding sack whap-whap-whapped over and over again with Coco's bloated own. To Rarity it seemed whenever the two pairs collided they milked ropes from Coco's spigot, but that might have been the case either way. She'd had enough experience toying with that greedy tunnel to know just a calmly buzzing buttplug was enough to leave Coco's faucet gushing.

Then, without warning, Coco came. Halfway through a harsh thrust her head snapped back, and a drawn out whorish whinny left her throat. From balls to brow she jerked, spasmed, spine arched and hindlegs kicked like a dog's.

In comparison, the activity of her junk felt less impressive.

At least, until it got the memo.

Her already massively inflated seedbanks swole larger. The sack tightened, and in her own mind Rarity heard their oceanic churn. Second a bulge appeared in Coco's cumpipe, gaining in size before shooting off with blinding speed. A blink later and the urethra yawned open, allowing a pressurized stream of steaming, pure white foalbatter to shoot out with the force of a firehose.

The first salvo painted the bedsheets. The second soaked them. The third flooded. By the fourth, the microphone could pick up on something thick and creamy plopping against the floor. Plup, plop, plohp, plop.

Several gouts of spunk later, Coco's first orgasm died down.

First, because Rarity knew what those kegs were capable of putting out.

First, because of intimate experience having to power wash her boutique.

And first, because the second arrived seconds later.

The amount Coco dispelled gradually waned, climax after abnormally long, absurdly productive climax. But when a small load for Coco was comparable to a large stallion's, that didn't mean for jack. And Suri, cackling, was all to happy to milk the living daylights out of her former assistant.

Rarity shuddered. At some point she didn't know she'd quit resisting. Maybe it was when the mascara started rolling down Coco's cheeks. Maybe it was when a cumshot so big and quick sprayed out it backsplashed onto the bed. Maybe it was when Suri started mocking her again, telling her she could never bring Coco to the withering heights of pleasure Suri could when she only had some wimpy plastic cock.

Either way, Rarity's lust won out. One hoof reached between her velvety thighs, and probed at her velvety lips. Bright blue magic teased and toyed at the inner and outer folds alike, drawing a wealth of juices and delighted groans in tandem. She rubbed, she stroked, she even tugged.

But she didn't cum, thank the Princesses. Degenerating to the point of masturbating in front of such an insult was mortifying enough. She counted herself lucky that Suri's climax impeded upon her own.

"Here's, hahhh. Another thinggg you'll nnneverrh be able to do." Suri, spittle foaming at the mouth, PLAP! PLAP! PLAPPED! her ballwreckers into Coco's haunches. She drov forward, lodging herself to the hilt and refusing to move aside. "Fill! This! Bitch! Uuuuuuuuup!"

Mistress and Pet brayed together. One moment and Coco's belly was bulged solely by the log of maremeat inside. The next, it was rotund with pints of sperm.

Audibly gulping into her ass, cum steadily inflated Coco's tummy to new levels. It sloshed, groaned, bubbled, and pushed her up. Once she looked a good eight months pregnant, the swelling ceased.

Only for a wide, fanning wave of spray to spew out Coco's mouth. Simultaeneously it poured down and shot out, like a broken main and tipped cauldron both.

Finally, as the white rapids tapered, Suri pulled herself out with a disgusting, sloppy sssshrrrlop! The jet of jizz that followed made the previous ejection of lube look like a trickle. It splashed against the sheets, the walls, the carpet, soaking into every thread of fabric it touched.

If Coco's clothes weren't ruined, they'd stink of sex forever.

Sex. Cum. Musk. Coco and Suri's overpowering dickmeat combined.

If it turned out to be the latter, Rarity decided she might keep those clothes.

The doorbell rang, as Suri resumed speaking.

"Fuh, fuh... phew! That's the best orgasm I've had in years!" Retaking her stance, Suri pressed her still rock-hard prick to Coco's oozing eclaire. "I'll give her back to you later. You can have her as much as you want, but know that I can take her back whenever I want, mkay? Consider it an act of, oh... generosity, that I'm willing to lend you my personal fucksleeve. Tata for now! Because I'm ready for round two~"

The feed cut. The doorbell rang again.

Stunned, silent, Rarity blinked at the blank screen for centuries. Behind her she felt her sodden pussy wink, its fertile nectar pitter pattering to the floor.

She turned, on shaky legs, and went to the door. She did it on complete instinct - didn't call out, didn't so much as look back to the TV. Her whole body felt on strings, piloted by ghosts more than herself.

She unlatched the lock. Drew the chain back. Eeeeaaaased the door open.

Shaking, trussed up like a present, was Coco. She lay on her back, hooves tied in place with black ribbon. In her ass thrummed a massive dildo, the seeming size and shape of Suri's cock. Coco's own cock, meanwhile, had been tied to her belly flat, the blossoming flare stuffed into her stretched jaw. Without the blindfold - though wearing the reeking, sodden remains of her lingerie - Coco's wide, shimmering, hazy eyes gazed up into Rarity's, faintly apologetic.

Around Coco's neck wrapped a new, black leather collar, bearing Suri's cutie mark. Attached to it a small tag, written on it text, which Rarity pulled into view.

"The dildo is custom made to match my own. Attach it to one of your strap-ons, and maybe you can make her feel a fraction of what I can.

Love,
Suri Polomare"

Rarity's hindlegs buckled. Her tail flagged. Her pussy winked.

And right on top of Coco's face, she fucking came.
