Hidden Desire

Fluttershy felt her body. It was taught, everything about her felt stiff. She struggled to breath, every gasp coming in desperate short pants. Her insides twisted and coiled, like an over-tight spring, screaming at her for their eventual, needful, blissful release.

There was nothing. Nothing else mattered to her, but what her body wanted. It was screaming at her—begging her—lusting for nothing more than the loving touch of a stallion, and for him to fill her, quench her thirst with the hot, soothing, touch of his creamy white bliss.

She could feel her wings stretching out over her back. Almost painful to the touch, they twitched in the cool air of Twilight’s personal study, shuddering with each convulsion that trailed all the way up her spine, through her neck, and right to the tips of her mane and tail.

Her lips were parted ever so slightly from the probing long object, revealing her sensitive insides to the cool air of Twilight’s study. She bit her lip, and her voice came out in a low, wanton, needy moan, like the sound an animal would make when they, too, were in need of her special attention.

“Ooooh... P-please, Twilight—” She bucked her hips back—the first involuntary, the second intentional as she felt her puss lips kiss the shaft, pressing deeper by barely an inch before Twilight’s firm hooves stopped she.

“Sh-ssssh...” There was the slight tingling, that caused Fluttershy’s breath to catch, and her hips to hike up a notch as Twilight trailed both hooves over her flank, stroking them in a soothing, gentle, stroking motion—one she hoped would help—but to Fluttershy she only felt her need growing. “Just relax, Fluttershy. It’s okay, it’s almost over,” she cooed.

She could only respond with a gentle whimper.

Twilight Sparkle, the Princess of Friendship and all around too good of a friend—at least if you asked her—leaned away from her friend’s nethers to finish her inspection. She removed her goggles, wiping the sticky secretions off with a wet towel, and made a mental note to take a shower, a long, hot shower—perhaps with friends—as she did a final pass over her notes.

“Okay.” Twilight squeaked with a definitive tap of her hoof. With her other, she tapped her chin and nibbled at the end of the thermometer she’d just removed from Fluttershy’s... undercarriage. All things considered, the taste was quite sweet, more so than Rainbow Dash, at least. “And you tell me that the cooler didn’t work?”

Fluttershy hesitated. Her face flushed a slightly deeper tinge of red as her ears pinned back. “N-n-no...” She eventually said. Her voice was barely a whisper. Although they were together in Twilight’s personal study, she was still at least a little weary about coming out with her situation.

It took all of Angel’s convincing, and a swift kick to boot, to just get her to leave her cottage to come over her.

Fluttershy gulped, and eventually added: “I-I tried everything, Twilight, th-the burning just won’t stop.” She tentatively lowed her behind, stifling a gasp as the cool crystal floor came into contact with her wet and sensitive—uh—sensitive bits. “I—ah—” she gasped, “I-I think I broke your dildo, too...”

Glancing over to Twilight, the Princess didn’t seem to have noticed the last bit. She was still frowning as she pored over her notes. “I see... I see...” She nodded, her frown deepening as her eyes trailed further and further down the long list of symptoms. Her eyes didn’t leave the page, instead her voice following perfectly, unwavering from the scientific method. “And did you try anything else?”

“Well, um...” Fluttershy’s face burned anew, as her memories shot back to that morning, of how she’d first ridden the dildo to its limits, exhausted the supply of fake cum, lube, and then her special ‘mayonnaise’ stash. She couldn’t well said she’d tried anything less than everything. “W-Well... I asked Zecora first, but her hoof wouldn’t fit...”

Twilight Sparkle, the Princess of Friendship, and by all accounts too good of a friend for her own good, did not bat an eyelid. It did twitch though. “I see.” She dropped her clipboard, and before it could hit the ground, a flash of magenta magic sent it on a one-way trip to the garbage room for incineration—by the gods, Spike had better not read it when he does. “Fluttershy,” said, with utter conviction as she turned to look ‘Shy in the eye. “I can say, with absolute certainty, that your estrus, right now, is possibly the single worst case of heat that I have ever encountered, and possibly ever will encounter.”

“Eep,” Fluttershy let out a tiny squeal—one that quickly turned into a needy whine as her heat reinforced its will upon her body. “B-But—I can’t be that bad!” she cried, “Isn’t there anything you can do? Any spell? Something!?”

Sadly, Twilight shook her head. “You are leaking on my floor.” Twilight gestured, Fluttershy blushed and paddled a few inches to the lift—an act that only seemed to make the problem worse as she trailed a puddle of slime all the way. The worst part is she couldn’t even ask Spike to clean it up, not again after the situation with Rarity. She had to clean it up herself and just the thought of it made her migraines come back.

“You are beyond science.

“You are beyond magic, Fluttershy, I didn’t even believe it was physically possible for a mare to edge this fucking long. If there was an Olympics for not cumming on time you would have every fucking medal on the roster.”

Tears welled in the corners of Fluttershy’s eyes. She gasped, her pussy clenched, sucking in and clamping down on the imaginary stallionhood that the floor did not have. “But there has to be something, Twilight!” she begged. Fluttershy threw herself at Twilight’s hooves, clasping at them like a foal to her mother crying for that dear candy in the supermarket. “Pleeeeaaaaase! I’m dying from this heat. I’d do anything!”

Twilight was knocked off balance, and she wobbled in places as she struggled to extricate herself from Fluttershy’s choke-hold without looking directly in her—Oh Celestia. Her eyes grazed over Fluttershy, and she caught the shortest glimpse of her dear buttery friend, eyes watery, lip quivering, ears folded back like a vulnerable puppy. It was like a stab to the heart, and it took all of her trained conviction not to give in. “You know how mares in heat are, Fluttershy, you have to wait and it will run its cour—“

“Pleeeeassssssss...!”

Fluttershy’s stare hit like a ton of bricks, a piano, potted plant, and an anvil, in that order. Twilight could feel her faculties breaking down by the millisecond—her poly-dimensional calculus was already slipping away through the tips of her hooves. “I—Uh—A—There is one thing, but I don’t really think it’s a very scientif—“

“TELL ME”

Twilight cast out a ray of her magic. She scanned the multiple bookshelves around her for the object she desired. A tendril of her essence snaked past every tome, scanned the corridors of her castle, before a single newspaper cut-out appeared in a flash from the bottom of a cardboard box beneath Spike’s bed—if anyone found it, she had her scapegoat—“The-This—“ She levitated the scrap of paper out in front her in a wavering magical glow.

Fluttershy snatched it out of the air and began poring over the words voraciously. It was all in Unicornic, but Twilight very helpfully offered her explanation.

“M-Manehattan has this new facility. They offer ‘special treatment’ to mares with your type of affliction, no records and no questions asked. As a Princess of Friendship—ponies have kind of assumed I’m the Princess of ‘Relationships’”—her air-quotes practically dripped with contempt—“I’m required to visit them sometime this month to ensure they are safe for operation, but I could t—”

“Take me.” Fluttershy whispered.

“—Take you with, yes.” Twilight nodded. “If you can manage just a few more days I can make t—“

“Now.”

Twilight gulped. She forced a grin on her face as she pulled herself away from Fluttershy, stuttering as she went. “... I-I’ll go pack my bags then!”

A furious clomp, clomp, clomp, and a slap, slap, slap, then a loud slam, smash, and crash, announced the arrival of the deafening slam, as the aging dark oak wooded door of apartment 8B was blasted halfway out of its hinges, and through that door stepped—I say stepped, but it was more of a tactical retreat under the hellfire of a woman’s rage—a tall, pale-yellow pegasus with a smug-ish smirk, ratty disgusting man-bun of a mane, and the off-kilter topping of a broken lampshade.

Zephyr Breeze stumbled backwards, flailing over his own hooves as he ducked to avoid the flying shrapnel. An electric toothbrush just grazed his ears, leaving a visible red mark as it buzzed along its trajectory. A pillow—laden with bricks—left its indention in the back wall and the neighbours’ apartment. “Baby, baby, Flutterbutter, my deary Sherry Squeeze, honeybear!” He truly spared her no expense. “Please just let me expl—” He was cut off as a heavy-set leather Minotaurian suitcase flew out of the apartment and slammed directly into his face, flooring Zephyr instantly.

“Get you of my sight!” A mare’s voice screamed, and a petite Pegasus mare—pink coat with a soft lavender mane, and glare that could cut through hardened steel. “I want you out of my sight” she screamed. “I don’t want you coming anywhere near me, my family, or out kids ever again!”

“But baby!” With a heavy and a groan, Zephyr managed to dislodge the suitcase from his face long enough to flop onto his back. With practiced precision, he assumed the position—hoof to chest, one knee on the ground, and the other reaching out to his beloved Clementine to ask her forgiveness. With the addition of the puppy dog eyes and a pouting lip, his act was complete. Zephyr reached for her hoof. “How was I supposed to know she wasn’t actually eighteen!?”

Clementines’ face contorted into a display of absolute disgust. Her gasp was near imperceptible under the volatile frothing of her imminent rage. “FUCK OFF, ASSHOLE”

She slammed the door.

In his face.

There was the led clatter of metal as several locks were slid into place, then the angry clomp, clomp, clomp, and the screeching as something was dragged across the wooden floors inside. Finally the door swung open with a creek. A large chest was deposited outside in the passage, along with several magazines, hairstyling products, and sprays—cans that clattered and rattled loudly across the floor—and then the door was shut and locked once more, for the final time.

The lantern outside was flicked off. Darkness descended on the apartment block as Zephyr was left standing out in the open, alone, with nothing but his eight-pound trunk, and several thousand bits worth of hair care products.

Oh, and the adult magazines. At least he had those.

Zephyr took a moment to take in the situation. Sure, it seemed bad, it always did. He turned down to inspect his scattered belonging, choosing first to pick up the old—now slightly dented but still okay—Minotaurian suitcase. The shop keepers told him it was made from real minotaur skin, though now it was becoming clear that wasn’t true judging by how easily his teeth had cut through the supposedly ‘indestructible’ leather hide.

He righted the suitcase beside the trunk and began gathering up the magazines, beginning with all the smut and then moving on to the more casual vanilla anal stories.

Sure, she was mad. Sure, she had reason to be. Sure, he miiiight be on a few government watch lists, but what was a silly little felon between soulmate?

He set down the anal stories beside the smut and began picking up the incest fiction, by far the largest books among the lot. It took both hooves, and a great deal of grunting just to get the first one not to stick to the floor.

And she did say she was eighteen, just...she’d missed her grown spurt, and the school uniform was just a— Zephyr facehoofed. “...I totally messed up, didn’t I?”

Yes, nopony in particular replied.

His ears pricked to the low, echoing creak of another door slamming shut further up the hall. In the distance, ponies’ voices were heard whispering from within their own little cubicles, and a television thrust to life through the ceiling above.

Zephyr took a deep breath, held it in, and let out a long, pained, groan. “Uuuuuhhhh...” He slumped against his chest, dislodging the stacks of smut, and pushed his head between his hooves as he pushed out the longest, most pathetic moan in his life.

This was the low point. “Ffffuuuu...” His voice trailed off, as Zephyr recovered his composure, though only slightly. His ears flicked back and then forward as he turned to his old friends—the magazine. “Nooo problem,” his voice only slightly higher than he would be comfortable with other ponies hearing. “I’ve been through this before.” He breathed, and turned to the first page of the porn mag. “Last time I had dear older sis’ to help me, but this time I’m my own stallion now!

All I need to do was find a new job—” He mentally scribbled ‘bone the secretary...s daughter’ off the list of things to do, and promptly added a big old NOT at the top of that list.

Zephyr stuck his nose in between the musty old pages, scanning every word—which was, surprisingly, very little—so instead he diverted his attention to the adverts on the back of the cover. “No...” Her hummed to himself, “What is there that I can do with a Doctorate in—” he whipped his scrubby mane, dislodging the lamp shade in the progress—“Fabulous mane styles?”

The obvious choice was to cut ponies’ hair, though it was unfortunate that they had to ban him from every barber shot, stylist, and boutique in the northern hemisphere. Apparently ponies don’t like being told what their mane looks like.

Teaching was also out of consideration, for obvious reasons.

Thus that left only a few options.

He flipped the page over to check the wanted ads, grazing past the ones that were simply for ‘bone buddies’ and ‘cuddle cuthulus’ and instead focused on the established names: Stallionley Wells, Assly Maredison, Pornbarn and... He shivered. Equestria Daily.

That last one was way out of his league, which means only one thing...

“Welp.” Zephyr slammed the book shut and took a stand. “Looks like I’m going t’ be a porn star!”

.

The building was tall and foreboding. With tall black walls and pointed dark archways the likes of which even King Sombra would get his rocks on to behold, it was nothing short of a spectacle to behold, a blight against the landscape of Manehattan, and an affront to the pharmacy and children’s hospital that saddled it on both sides—left and right respectively.

There were no visible windows—at least as far as Twilight could tell, there weren’t—and any signs otherwise had been so thoroughly painted over she could have sworn whoever must have done it must have just taken a hose to the walls and called that the day.

But that wasn’t what had her attention—well, it did for a bit, but something else had so thoroughly drawn her eye that it was practically impossible not to notice the building, and utterly incomprehensible of how anypony could have even approved of this abomination.

She checked the address on her notes, double-checked it, and even asked a passing stallion on the way, and everything seemed to point to this same location.

Even still, she was having a hard time grasping the concept. That this. No, this. This building, the one with black walls, red curtains, and the undeniable smell of something wafting from the doorframe—the one that she could described as the utter, unfiltered, visual-audio assault of her senses could possibly be a ‘Mare ‘Till Health Institute’.

It just wasn’t possible. No clinic look like this, and no clinic would ever have its name emblazoned in burning yellow-and-gold neon lettering across its façade like a common whorse house. And it certainly didn’t need the incandescent blue stallion cock flaring from the top of the ‘Y’ in ‘Assley Maredison’ to stretch all the way to kiss the bottom of the last ‘n’ at the farthest corner of the building.

At the very least, they could have made it anatomically accurate—maybe more detail on the flared head, she didn’t know, it was a bucking neon dick on the wall for Celestia’s sake!

Every two the front door inside would revolve and a new stallion would come trotting out with a box of various objects balanced precariously on his back. Some of them were sporting moustaches and some particularly handsome sets of leather chaps, others had cowboy hats, and at one point a stallion covered head to toe in loin cloths trotted directly between herself and Fluttershy like it was a perfectly normal thing to do.

They both waited for the last stallion to be out of earshot before Twilight finally spoke up.

“...well,” she said. Twilight smacked her lips. She continued staring at the sign—seriously, the shape of that thing is not even close. A kindergartener could draw a better prick than that. “This is... Not quite what I expected.”

She eventually tore her eyes from the sign. There was no reason to every look at it ever again. There was no reason to. It was burned into her retinas. She will see that dick for the rest of her life, every time she closed her eyes, or even blinked. It might even haunt her in her nightmares.

Twilight blinked.

A shiver ran up her spine as she retched at the memory of the image.

“I’m sorry, Fluttershy. I honestly thought this was going to be a more legitimate establishment.”

Looking to Fluttershy, the mare seemed to be frozen in shock. Her face was flushed red, and she hadn’t moved a muscle since they’d come around the corner. The mare was like a statue, the only sound to be heard was her panicked breathing, and the sound of her pupils constructing into tiny pinpricks was almost deafening to her ears.

Twilight reached across, continuing as she began to usher Fluttershy away. “I’m really, really, sorry this didn’t work out the way it was supposed to”—At first Fluttershy didn’t seem to move. Her right hoof lifted but she was hesitant—“I promise, as soon as we get back to Ponyville I’ll start looking through my books again to—”

Fluttershy jolted back to attention. She blinked and her ears splayed back. She pushed against Twilight, shoving a hoof in her face as she cried. “Wait!” She squealed, then quickly recoiled back using her mane as cover to regain her usual unsure self. She blushed deeply beneath the pink locks as she quietly whispered. “I... I—I-K-Kind of want to go inside,” she said.

“Y-You do?” Starlight stared incredulously. She blinked, and the cock quickly flashed across her face in ultraviolet. “Aahhh!” She buried her face in her hooves to hide from the monstrosity, which only seemed to exasperate the problem, so she was forced to ignore it and put on a half smile as she turned back to Fluttershy. “I mean—” she coughed “Seriously!?”

Fluttershy nodded. “Y-Yeah—” Her face was starting to look like an over-ripened tomato, to the point that Twilight could have sworn she saw the stem—or maybe it was sweat, it was hard to tell with the amount of fidgeting the pegasus seemed to be doing. “I mean, y-You have to review it, right?” As-As a princess?”

“...”

Twilight dared one more look at the building, and they both stepped aside to let a mare past. Twilight bit her lip as several stacked layers of latex fabric passed between their eyes, and then a tall, nervous-looking stallion trotted after draped in a thick black shower curtain. Fluttershy’s eyes followed after him as he passed.

“It’s not that type of facility, Fluttershy,” Twilight said.

They both trotted aside where nopony else was likely to interrupt them, and Twilight leaned in closer next to Fluttershy so they both could whisper without being overhead. “Seriously, I don’t think I’m needed here. There’s nothing for me to ‘approve’ here. Brothels are permitted under the freedom of sex act, and I’m sure they’ve already gotten their license.”

“Oh, come on, Twilight,” Fluttershy pushed back, slightly more insistent. She leaned into the huddle, closing off the outside world as she put on the sad eyes. “Won’t you do it for me? Please?”

An added flutter saw Twilight’s heart begin to melt.

“I’m sorry, Fluttershy,” She squeezed her eyes shut—but quickly opened them again for previously discussed reasons. Now that is a pain worse than death. She just had to put up with the leser of two pains. It was either that, or this. “—but this place is not the kind of—“

As she shook her head, Fluttershy doubled down on the assault, biting her lip asn looking at Twilight with blurry eyes like she was ready to cry.

“No, no, no, no!” Twilight doubled down on her stance. She stamped her hoof as she recited her mantra. “No, no, no. I’m not falling for that again, Fluttershy. We are not going into a brothel just so you can sate your heated desires.” Fluttershy’s stare intensified. “A-And need I remind you that you’re in heat? If something goes wrong, I’m not going to be responsible for—“

Fluttershy added a little whine, lowering her ears as she let the tears shimmer and shake. Her bit lip began to tremble.

“—whatever happens to you.”

“Oh...” ‘Shy let up on the stare long enough to glance to her own hooves. Her face softened, and her eyes were hidden again behind her pink locks as she breather a long sigh f resignation. She scuffed at the ground and whispered, “I—I guess you’re right...”

Twilight let out a long breath, her back and muscles relaxing as the tension slowly left her. She hadn’t even realised she’d been holding her breath, and even now she could feel her heart palpitations acting up at the memory of Fluttershy’s cuteness onslaught. Any long, she assumed, and Equestria might just be down one princess. “Gooood...”

She dragged out the word, taking a moment to recollect herself. She set a hoof on Fluttershy’s shoulder, steadying the mare’s shivers as she began to usher her away from this horrible place; this horrible place and that horrible—Twilight blinked. EUGHTtHTTEFNOIG

“I’m glad you could see it my way, Fluttershy. Now let’s go home and we caaann— “

Fluttershy suddenly dropped out from under her hoof. She tumbled to the ground, tripping Twilight as she clasped her hooves. “Oh, please-please-please-please, please, pleeeeasse take me, Twilight!” Fluttershy’s voice reverberated across the square as she cried out, screaming with pleading agony as he looked up at Twilight, tears streaming down her face. Her cheeks were red and her ears were splayed back as her massive blurry eyes tore into her soul.

“Fl-Fl-Fluttershy!?” Twilight blurted out. Her voice cracked and she instinctually ran a scan across the surroundings, her face burning bright red with embarrassment. Stallions and mares had just stopped to stare, and she could already make out the circle of ponies forming at the edges of her vision.

All this while, Fluttershy still continued to sob and cry at her hocks, as scene only made worse by the rising scent of a mare’s arousal wafting from her dear friend. “Twiiiiilight,” she whined between sobs.

Some of the stallions turned to their significant others and whispered into their ears, flashing a mischievous grin towards herself and Fluttershy. Some pumped their hooves in the air, and others gave the thumbs up gesture, all of which only served to make Twilight’s face turned an ever deeper shade of crimson. She couldn’t even close her eyes to hide away from the embarrassment, lest she face IT again.

“I-I—” She started backwards, dragging the slobbering mare along with her. She glanced left, then right, then left again, the panic only rising by every second she refused—“Ok—Okay, fine, fine!” Her defences crumbled like a castle of shortbread in the wake of an oncoming hurricane. She held out her hooves to placate the poor thing at her hooves. “I’ll do it, Fluttershy, you can stop now, please, please stop crying!”

Fluttershy’s sobs continued for a second, and then slowly diminished as her ears perked back up. Her back stiffened and, with hesitation, Fluttershy look back up to lock eyes with Twilight’s. She sniffled. “R-Really?”

A thin smile spread across her features. The tears still welled below her shimmering eyes, but the slow ebbed to a gentle trickle as Twilight gently nodded. “Y-Yes. We’ll do it—”

Fluttershy’s face lit up at the words and she leapt off the ground to pull Twilight into a massive hug.

“But!” Twilight held her off with a hoof. “We’re doing this for medical reasons. We go in, we go out. We’re not staying for any reason, and as soon as your estrus is resolved, we’re going back to Ponyville. Capiché?”

Fluttershy nodded. “Capt-Cumpth—Y-Yes, Twilight.”

Twilight kept her face stern for a moment. She looked Fluttershy up and down, then, eventually, she relaxed, letting out her own sigh of resignation. “Okay...” She turned around, waving for Fluttershy to follow her inside. “Fluttershy, you really need to stop hanging out with Rarity in those spa dates. She’s starting to rub off on you...”

‘Shy hummed her agreement as she followed behind. “Y-Yes Twilight...”

The heat.

Oh the heat. Celestia, it was so unbearable. If anypony had told her it could get worse she would never have believed them.

Somehow the insides of Assley Maredison had this distinctive smell of a stallion’s musk. It wasn’t overtly noticeable, but enough to send her sense—and other anatomy—into a whole new wave of fervour. Whenever her care books had told her how bad it was when her animals would go into heat, how they would go so far as to hump nearly anything, including the sofa and her own legs, she’d questioned the legitimacy of the book.

I mean, how bad could it be?

The answer: Pretty fucking bad.

Right now if she saw anything—and if she could trust her nose because it was pretty dark in this place—anypony roughly phallic-shaped she’d hump the bit out of that thing and ask questions last.

It didn’t even help that she was currently stuck in a particularly precarious scenario: jammed into the middle of the swivelling entrance, shivering with her hooves clamped to the edges of the doorframe, her head inside, and her marehood on full display to the world on the other.

She felt herself wink, a rivulet of fluids splattering across her dock and flanks, and her insides a somersault. They twisted in on themselves, forming tight, hot, fiery like the depths of Tartarus that screamed at her for some kind of release. Any release.

At the same time the butterflies in her stomach were staging a haiku. Not a coupe, a haiku. Apparently they were already finish with the hostile takeover and were just cleaning up the spoils.

Her stomach wretched. “I—I—I don’t know about this, Twilight.” She swallowed the butterflies and squeezed her eyes shut, trying all her best to ignore the scent of several stallions—and sound of moaning in the distance, and that gently thump, thump, thump coming through the wall. “I-I changed my mind, I don’t want to—“Eeep!”

Something brushed against her flank, causing her entire body to stiffen. Fluttershy’s eyes shot open, and she looked all around her. The lobby, luckily was mostly empty, through the dim lights were making it hard to be certain. She blushed all the same.

“Uh-T-Twilight?”

Another motion and a soft tingling accompanied the tickling sensation of somepony moving her tail.

“Twilight!?” she repeated again, louder this time. “Is that you?”

The motions stopped for a second, then quickly resumed.

Fluttershy swallowed. Surely it had to be Twilight. What kind of pervert would come to accost a mare who’d gotten stuck in a revolving entrance? Certainly not the type to regularly visit a brothel, right—

A sharp poke and a shot of electricity ran up Fluttershy’s spine, causing her to squeal as she was forced through the entrance. She practically flew—for about an inch before Fluttershy face-planted directly into the plush carpet below.

“Sorry about that, Fluttershy...”

Twilight’s voice all out over her, and shy caught a glimpse of two purple legs straddle her on both sides as her face sunk deeper into the comforting embrace of the, admittedly sticky, welcome mat. She was hauled back to her hooves and made to stand beside a smiling Twilight—the princess levitating a bottle of lubricant paste in her magic as she looked Fluttershy up and down.

“I had to go get some gel from the convenience store, and when that didn’t work, well...” Her cheeks turned red and Fluttershy felt her own blush returning as she followed Twilight’s gaze up to her horn. Twilight licked a hoof and extinguished the last sparks of her spell, then did a quick once-over of her friend. “So...” She waved a hoof, and ‘Shy retracted behind her mane as she felt Twilight’s eyes scan over her body. “...What did you say earlier?”

“Um, uh...” The floor suddenly became very interesting—soft, red carpet with a slight speckle to it, with a slight spring to it that gave way beneath her frogs. It was nice, certainly a perfect fit for bedroom, or her grand-mare’s living room. Really, it could almost be put anywhere, except the bathroom. That was out of the question no doubt. “N-Nothing,” she squeaked, “Let’s just... get this over with.”

Fluttershy pushed back her mane, tentatively giving Twilight a smile as she began to inspect her surroundings. The reception area wasn’t large, quite the opposite, her cottage living room had more room than this.

There were couches and potted plants dotting the corners, with the incandescent haze of several blue and red glass gems that hang over them. One of them flickered and buzzed loudly, adding a shimmer of blue light to its surroundings.

The carpet, of course, led the way, parting off down two directions: a passage to the left, leading off... somewhere. The end of the passage was too dark to make out past the first few doors, though the sound of ponies’ moans and mare’s groans was more than enough to placate her curiosity—a tickle her interests.

Swallowing, Fluttershy steadied her breath and put her back to that passage, instead joining Twilight as they did their rounds, trotting down the soft carpets.

They both arrived together at the reception desk—a large phallic object that looked more at home in a shoebox under the bed than on public display, it practically commanded for any mare’s attention. From its mottled veins and its flared head that sunk into the soft carpet, to the stack of papers and potted plant that wobbled precariously atop the misshapen balls, the only words that could make their way through Fluttershy’s head—and her mouth, was. “...Wow.”

Twilight gave her that smirk—the one as if to say ‘I know, right?’ and she wiggled her eyebrows. Fluttershy almost gasped and she quickly covered her mouth to stifle the giggles as Twilight reach out and gave the bell three quick chimes.

Ting, ting, ting

Nothing at first.

She frowned and rung it again.

Ting-ting-ting

Still nothing.

Fluttershy licked her lips. “Um...” she squeaked. “Are we sure they’re—

“Yes, welcome!” A young mare popped up from behind the desk, sporting an unnaturally welcoming grin and a—Fluttershy could almost swear it was a slightly psychotic look in her eye. She almost jumped out of her skin, squealing as the mare leaned over the desk to greet both of them. “Sorry I’m so-so-so, so I’m late,” she said. With her left hoof, she began shuffling through the papers, using the other to straighten out her mane. She squinted and her muzzle scrunched up as she began reading from her page. “Welcome to Assley Maredison! Speciality in Sass, Ass, Crass, and Grass, where the mare’s dreams become more than a reality!”

She slammed the page down with a definitive slap against her dick desk, making the whole thing wobble and lurch. The other papers slid to the floor and the pot plant—Fluttershy watched it closely, still struggling to catch her breath and keep from having a heart attack—wobbled with a weighty threat.

The receptionist didn’t seem hardly as concerned as she hampered the desk’s movement with her upper weight and leaned across the desk. “How may I help you miss...” For the first time in the few second’s they’d been together, the mare laid eyes on her customers and immediately cut herself off with a gaps. “Princess Twilight Sparkle!” She faltered, almost falling off the dick. “Oh my Celest—” she gasped again, slapping her hooves over her mouth. “I’m so sorry, I didn’t mean t—”

She shook her head, further knocking more papers off the desk. “Y-You must be here for the inspection! I’m so sorry for keeping you waiting, I-It’s my first day and...”

“Actually...” Twilight leaned back, albeit just enough to keep their noses from touching. For the rest of the way, she pushed the receptionist back into her own side of the desk with a hoof to the chest. She flicked an eye to Fluttershy, and the receptionist’s gaze followed—attention from both setting square on her. “...We’re here for her...”

The receptionist gasped oh. “Oh.” She blinked, then gave Fluttershy another, closer looked, and her ears lowered slightly—that’s not a good sign.

Fluttershy took as her queue to say something. “E-E-Eeeee—” She cowered behind her mane under the combined scrutiny.

The receptionist nodded, her face becoming deathly serious. “I see,” she said, and produced a stack of papers, a quill, and an inkwell from beneath the phallus—no idea where she keeps this stuff. “You can take care of the paperwork later. She’d going to need immediate attention—“ she said this with a wink to Fluttershy’s corner—“This is possible the worst case of hyper-sensitive estrologynocholysis I have ever seen.”

“You can tell that just by looking at her?”

“Princess,” she said, flatly. She levelled Twilight in her gaze and pressed the hoof with the quill into her chest as she said, “With all due respect, I can tell that just by smelling her. I’m quite surprised you hadn’t noticed.”

“Well,” Twilight’s eyes shot to Fluttershy for a split second, and then back to the receptionist. “She does work with animals...”

“No, no, no... Not that smell, the other smell. She’s stinking up the whole whore house, the entire building is practically reeking of sex!”

Fluttershy looked between the two mares. She leaned in close and reared up on the desk, whispering in her most urgent of. “Um, girls?”

“How are you even able to make such an assessment? You’re not even a physician!”

“I am too!” the receptionist shouted back. She crossed her hooves and gave a proud nod in Twilight’s direction, pointing to the wall of plaques hanging behind the dick—counter. Dick-counter. “We are an accredited institution.”

“And a horse house,” Twilight shot in jest.

“Um, girls?” Fluttershy interjected. She was promptly ignored as the receptionist nodded.

“And a horse house,” she said. “It’s on the sign.”

Twilight opened her mouth to object, but then the receptionist’s words sunk in giving her pause. She frowned in thought, rather choosing to proceed with a little more tact. She cautiously continued. “Uuuh... What sign?”

“The one out front. It’s underneath the dick. Did you seriously not see it?”

Twilight blinked. A shiver of revulsion ran all the way up her spine and she cringed. She also resigned her defeat. “...oh.”

“Twilight!” Fluttershy shouted, giving both mares a jolt. She caught Twilight’s eye, and the mare flinched.

Twilight’s ears pricked back as she locked eyes on a very much peeved Fluttershy and sucked in a breath through her teeth. “Oh, oh—” Her attention darted to the receptionist, to Fluttershy, and then back to the receptionist. ‘Shy began rapping her hooves against the misshapen counted. “Right, right,” she nodded, “H-How much is this going to take? To, um”—She swallowed—“To help my friend?”

“For you?” the receptionist’s eyebrows rose. She nibbled the end of her quill in thought. “Mmm... Nothing.” She then pointed to Fluttershy with the other end of the feather, sending a splattering of ink all the way across her stack of papers. “For her: it’s about an afternoon. You can leave her with us and pick her up in an hour.” She quickly scribbled a few details down on top page from her stack, and shifted it across the phallic table, rotating it as she did so to let Twilight read over the details of the contract. As she did so, she fluttered her eyes, musing with a sultry smirk. “That’s juusst enough time to consider us for approval as a medical institute.” With the other hoof, she slid a stack of bits across the desk to rest beside the page, just close enough to be within the Princess’ field of view.

Twilight remained expressionless, watching with bemusement as the money pushed well past her side of the desk. She lifted the page in her magic, just moving it out of the way as the bits slid down the slope, teetered, clattered, and rolled to the ground at her hooves, where she promptly ignored them. “...I’ll consider it,” she said. Twilight promptly scribbled her signature on the page and handed it across the desk—sans any royal decrees, and turned to her friend. “Fluttershy!”

“Yes!” Fluttershy jumped to attention, letting out a startled eep as she toppled backwards onto her haunches. Her lips grazed against the soft carpet, sending a tingle up her spine that only served to worsen the matters—adding an extra tremor to her normal shaking demeanour. Curse this place and their good taste in rugs!

“Since you’re going to be a while, I might as well go run some errands—Rarity mentioned to me a few days ago that her boutique was on fire, and I’m supposed to go put it out. I trust you can stay here and get everything sorted out.” She turned to the receptionist and inclined her head. “Thank you, miss, um...”

“Device.” She bowed behind the desk. “Plot Device, Princess. And think nothing of it. It’s an honour to assist the acquaintances of Royalty.”

Twilight fidgeted her wings. “Yes, well...” She puffed out her cheeks and turned to leave. “I’ll be back in an hour then...”

With Twilight gone, Fluttershy returned to sitting on her haunches looking around the room feeling more or less like a lost puppy. She swallowed, glancing back at the desk. “Um, where do I—“

Plot Device gestured to the hall to the left—the same one that made Fluttershy’s stomach turn. “First door on the right, our assistants will get you sorted, and the doctor will be with you shortly.”

“Oooooh...” The moan was drawn from her lips with a hearty breath, like all of the stress and tension leaving her body in one, pent up, agonizingly long, heaving sigh of relief. Her body was like butter, soft and malleable, melting in the deserts of the sun’s baking heat. Every aching bone, every sore muscle, tendon, and spine, were like putty to be shaped and moulded by the expert touch of her master masseuse.

She was at their complete mercy, and their mercy was good. “Good, Mrs. Shy.” A mare’s voice, thick with a Perinian accent, wafted over her back dancing across the air on the current of jasmine rocket that just tickled the senses. She whispered soothingly, careful not to break the blissful tranquillity that enveloped them, with a melodic lull as worked her silken frogs into the crux of Fluttershy’s back.

Every motion alone elicited a tiny, tingling jolt of excitement that tickled every nerve right from their core to their tips. “Let it aaaall out,” she whispered.

“Ooooo...” Fluttershy responded in kind, with a long heated moan as a shiver ran up her spine. “Oh...” Her back arched involuntarily. The joints in her back jostled and loosened, jostled apart by the steady, rhythmic thrumming of the vibrating bed. Its sculpted surface shaped itself to her form. It fit perfectly to her body, caressing it in a gentle embrace as the gentle shakes shook her to the core, putting just the right amount of pressure on just right spots.

Another moan escaped her lips before she bit it off, into the soft and squishy mat.

All she could do now was ride it out, lie there and bask in the warmth and the comfort, the absolute bliss of being waited on hock and hoof. Unclenching her teeth, ‘Shy let go of the mattress and allowed her tongue to drape out over her open maw, panting with hot and tired breaths

Tartarus itself could rip itself open—Equestria could be drenched in flames and misery, her friends defeated and enslaved, and none of it would—None of it could interrupt her from this one perfect moment, or even stand to attempt to sour this sweet cozy glow.

The edge of the bench tilted and decompressed, the springs ringing their protest as the other mare moved from her own position. Her hooves—that blissful touch, parted from ‘Shy for but a moment, causing her lip to quiver, a gentle whimper as she craved for her gentle embrace for just one second longer.

The vibrations kicked up a notch, pushing a torrent of fresh sensations through her lower body and abdomen. Fluttershy’s breath got trapped in the back of her throat as the vibrations drilled deep into new recesses she hadn’t even known existed, and then her breathing hiked up in response and ending in a low, agitated groan as the vibrations slowly peaked and descended back to their original state.

Her masseuse—she didn’t know her name, but Celestia she was a genius—leaned in beside the bench. Her lips grazed the sensitive hairs beside Fluttershy’s ear and she could hear her smack her lips, almost invitingly so. “Before we begin...” she said.

A moment of pause as the bed’s vibrating went through another rise, mound, and descent. Fluttershy’s own panting and the gentle humming of the bench filled her room, and again the mare continued. “Would you like to be with the blindfold?” She smacked her lips, breathing directly across Fluttershy’s ears, causing them to twitch. “Many of our special ‘clients’ have expressed an interest in being deprived of their senses. They... enjoy the sense of—how you say?—The sense of helplessness that comes with.”

N-Not to mention the excitement of—Fluttershy felt her blush return in full force, her marehood aching against the vibrating bed at just the thought, of the implications—of not even knowing who it was that would be dominating her.

The room around her gradually grew warmer, and Fluttershy became aware of a motion against her back—a stiffening in her muscles as her wings began to unfurl of their own accord. It was, admittedly, once a nightmare she’d had: one where she’d wake up tied down, helpless and blind, whilst somepony went around touching her body, stroking it, teasing it, doing whatever they wanted whilst she was helpless to even move to stop it or event cry out for help.

Those nights she would wake up crying in her sleep, but her cheeks would be hot and her wings were stiff as card. She had no idea why, but she always went back to sleep hoping she would have that dream again. It wasn’t until much, much later in her life that it started to make sense. After her second and third heat, only then did she realise what it actually mean, but it was never something she could ever consider as more than just a dream, a nightmare of a dream, a fantasy.

“Y-yes, please.” Fluttershy quickly jerked her head, squeaking out the words as quickly as she could, before any form of common sense could kick in ant tell her how bad of an idea this could be—she’d be putting herself out there at the mercy of a complete stranger.

The mare returned with a satisfied hum, her voice turning coy as her breath tickled across Fluttershy’s sensitive right ear.”Oh, you’ll be in for a treat...” She could imagine the mare’s smirk, even as she disappeared away from her for a second.

There was the dim glow of magic, and a ribbon of black fabric flittered past the corners of her vision, then everything went black—not even the barest signs if light could be made out through the pitch black abyss. The last remnants of light were quickly snuffed out around her as the knot was tightened behind her ears and the corners of the blindfold laid flat over her cheeks.

Now, with nothing else to see, all other senses were heightened. The buzzing of the bench against her barrel, etching away at her insides and drilling home little rivulets of pleasure to her very core, the constant humming turned then thum, thrum, thrum as the mechanism of the bed worked away underneath her, and the gentle clip-clop of hooves against the floor as a mare trotted circles around her unseen.

“Mhm. Good.” A door creaked in the background. Another slammed, and somewhere far away another mare moaned through the walls. Another pair of hooves joined the first not far behind. The bench tilted, and the mare’s breath was again by her side. “Now that we are ready, the procedure may begin...” She paused, the door creaked behind them. “...Doctor Breeze will see you now.”

Somepony gasped, and Fluttershy’s ears pricked to the sound, locking on and swivelling to the source behind her as best they could. Her mouth folded into a frown, then a sly smile as she arched her back. Her hooves were preoccupied beneath the bench, but that didn’t stop her squirming to raise her tail, flash her flank high, freeing her clit just long enough to shoot out and kiss the cool fresh air.

She breathed out, humming in one long breath. “Oh, that voice sounds...”

.

.

...Familiar.

Something was familiar, very familiar; too familiar. Zephyr Breeze has frozen on the spot as soon as he stepped into the room. He’d almost dropped the clipboard when he set eyes on her—the only thing stopping it from falling now was his shaking, stiffened, grip that was threatening to crush the delicate plywood card in his hooves.

He swallowed again, and closed his mouth. “Oh, that voice sounds familiar...” Fluttershy cooed, giddy almost, as she lifted her tail and wiggled her but, flashing Zephyr with the last thing he ever thought her would see—her clitoris was bright and engorged, like a puffed out bead of pink flesh. Her wings were stiff, throbbing almost whilst the rest of her yellow form was laid out prone against the form of the massaging table.

A second mare, a pale, washed-out pink with an almost white mane, flashed him a wink from her position against the side of the bed. She waved to Zephyr, and her felt himself slowly drawn further into the room. “She is ready to see you now,” Aloe Blossom said, smiling coyly as she trotted past. The tips of her tail flicked past Zephyr’s nose, giving him a quick peck on the chin as she passed. “We will leave you two alone,” she sultrily growled.

The door softly clicked shut behind them, followed with the faint click of a lock.

Zephyr was let alone—well, not alone—he was left starting, wide-eyed, at what he could have sworn was his own sister, splayed out against a massaging bed with her pussy on proud display, ready and willing for any stallion that came along to take her right then and there.

Even if that stallion was her brother.

He gulped.

It was loud enough that the mare’s ears pricked. Her whole body stiffened, and chains below the bed rattled as her hooves reflexively pulled against their restraints. “H-Hello?” Oh lords, even her voice sounded the same.

Zephyr’s hooves were like putty below him—The ground pitched and heaved below his. His head was swimming, and the room began to spin as his heart beat higher and higher into his chest. Her coat was yellow, her mane was pink, flowing even, with that cute little curl that he always wondered what it felt like to touch.

Her ears perked and twitched with every motion, her entire body stiff and tense, as if waiting for something. Slowly, Zephyr made his way to the bench. Her was forced to lean against it—his mouth dry and his legs unable to work as his eyes slowly took in what he was seeing in front of him.

This couldn’t be. It’s just—It couldn’t. She couldn’t—He looked at the clipboard.

It didn’t mention anything about a name. There were no identifying features clearly made out. Whoever had filled it in had chosen the ‘non disclosure’ clause on almost everything, with a quickly-scribbled signature at the bottom in pale blue ink.

A cursory glance back to the mare had Zephyr’s heart racing. The curves of her body looked... alien, almost. To see her in this position, to see her here and so vulnerable, so... lewd... The only other time he’d even seen Fluttershy in anywhere close to this condition was the time he’d accidentally caught a glimpse of her sleeping in her room, and even that was just a few seconds. As soon as he’d realised she was having another of those wet dreams, he’d run away blushing deeper than ‘Shy at her play recital—a colour one could only imagine let alone describe.

“Mhmmm...” She groaned, and Flutter—No, not Fluttershy. This was some other mare. It had to be a coincidence. She groaned, agitated and impatient, as she lifted her backside higher into the air. Her wings were stiff as they could possibly be, spread out and shaking as if crying for relief.

The buzzing of the table snapped Zephyr back to the moment, to his task at hoof. He was a doctor, kind of, and he had a patient to take care of, kind of... It didn’t matter if she looked like his sister, or even h—h-had the same cutie mark.

“Oh sh—” He gasped, and slapped a hoof over his mouth. A shiver ran up his spine as the realisation dawned on him. The pieces came together and they were all pointing to the same conclusion, not one her particularly liked. This could be his sister. It was very likely that she was, but at the same time—aren’t there several ponies with wheels as cutie marks?

If there were other ponies with wheels for cutie marks, then it stood to reason that there had to be other ponies with pink butterflies who just so happened to be also good with animals. And maybe they also had pink tails with pert behinds.

After all, maybe this was all just another one of those crazy coincidences.

Yes, it had to be. He silently nodded to himself. She whined insistently, and Zephyr’s eyes were glued to her behind as she arched her back, spreading her legs out ever so slightly to give him another quick view of her dripping wet marehood.

Her heat was bad, possibly the worst he’d ever seen. Fluttershy wasn’t the kind to go into heat like this—at least not that he’d ever seen. If she did, she was too much of a wallflower to dare leaving the house in that condition let alone coming to a hoarshouse-slash-physical health clinic to get it taken care of.

No. She’d have her own remedies. She’d know how to take care of it herself, like the big sister she was. She wouldn’t come here, and this definitely wasn’t Fluttershy... which left only one thing.

Zephyr unclenched his eyes. His grip on the edge of the bench loosened and her slowly pushed himself up, and to the side, aligning his gaze more directly with the back of the mare’s behind. She was in need, he thought, and there was only one stallion that could get the job done.

“Celestia, save my soul...” He silently whispered under his breath and then, biting his lip, Zephyr lifted his head and whispered just loud enough for the mare to hear. “Ma’aa—” Her bit his tongue. Ma’am wasn’t good enough. He was supposed to be sexy, more intimate, the interviewer told him—a phrase he’d heard far too many times in the context of a marriage counsellor.

“My dear...” he began again, voice low and sultry. She couldn’t see him, but he added the patented Breeze Eye Wiggle and Shit-Eating Grin™. The success rate was... Objectionable. It worked perfectly in clubs, and anywhere else? They always either ran away screaming, or whipped out the bear mace, sometimes both. After the fifth time it stopped burning, so who can complain? He cooed, “My dear little Flutterbutter”—A twang of regret cut through his heart, and Zephyr silently cursed himself for not coming up with any pet names that weren’t a play on his own sister’s name.

Slowly, he reached out to grasp both sides of the mare’s flank, squeezing her cutie marks between his hooves. “Please relax,” he breathed. Her body tensed for a moment, but the vibrations of the table worked quickly and she was soon again putty under his hooves. Her pert behind was soft, her fur warm and prickly. Little tremors rippled through her muscles under his touch, energy shimmering through her body as he slowly lowed himself down behind her. “Let ooooold Ze—Doctor Breeze take care of you”—As he dropped to his knees, her behind rose up to come in line with his face.

Still arched and ready, her tail was flicked aside to give an unobstructed view of her perfect behind, and oh what a behind it was.

If this were anywhere else—in their house, or a picture somepony was showing him and they told him this was his sister, he would have no doubt believed them. It was that perfect a match. Her yellow, soft, fur thinned and gave way to the delicate pink folds of her feminine flower. Her anus was twitching, clenching and tightening in perfect rhythm with the ripples and pulses that passed over her engorged lips.

He counted. One, two, three—Wink—one, two, three—wink. It was like a perfectly times clock. Every three pulses, her clitoris would pop out, kiss the air, and then suck back in between her folds. One, two—Wink—One, two—Wink. The pace increased as he tightened his grip, a too did the clenching of her anus change from a beating pulse to a constant, flat-line tension.

Zephyr licked his lips, and took a deep breath, letting the musk scent of a mare’s heat envelop him, cloud his mind, and wash over him with the thoughts of thrusting deep into her fertile depths.

He let his tongue poke out form between his lips, and pushed all other thoughts out of his mind. This wasn’t what he thought it was, he wasn’t about to pleasure his sister, he wasn’t about to make her scream with pleasure as her thrust his tongue deep into her pussy and massaged her inner depths.

This was a complete stranger, a mare he didn’t know, with absolutely no relation what-so-ever and there was no way he could possibly have a raging hard-on at the thought of ploughing this mare—a mare that resembled in every way possible his older sister—into this bed until she screamed his name.

There was just no way.

.

.

She was poised and ready. Her body worked on autopilot, back straining ever further—tail flagged and winking clit exposed to the world. Everything about her screaming rut me, rut me now and yet nothing was happening.

Her back was bent almost to the point of being painful, she could barely feel her wings, they were so stiff—practically throbbing against her back with every pulse of her heart, and yet the stallion didn’t seem have made any move since he approached the bench.

The worst part is she couldn’t even find out what he had in mind. The chains allowed precious little movement, and the blindfold forced her senses to hone in on even the slightest little details—the sounds of her own ragged breaths, the sensations of the vibrating bed beneath her was now a gentle, soothing hum. She could hear his breathing, and she could feel her whole body aching, screaming out for some kind of relief.

And she would have ask for it, too, but then, before she had her mouth fully open—or rather her tongue back inside it—something changed.

Two hooves griped down on her cutie marks, sinking into her flanks and spreading them. The sudden touch sent a shockwave of tremors through her entire body, and a lightning bolt of terror to arc through her. Fluttershy gasp. “Ah—” She swallowed, and let out her breath as the wave of pleasure washed over her. “Ahhh...” Somepony’s tongue had just danced across her lips. Not enough of a touch to do anything much, she wasn’t sure if they had even parted her labia, but it was just enough for her to notice, to leave her wanting more...

.

~ ~ ~

.

Zephyr’s eyes were screwed shut as her dragged his tongue along the mare’s hood, lapping up the thick dribbling of arousal that was dripping from her entrance. It was strangely sweet, with the faintest hint of pineapple, far nicer than Rainbow Dash’s, to be certain.

But there was also something familiar about it, something he’d tasted before but couldn’t put a handle on exactly where it was.

He licked again, this time delving slightly deeper. Zephyr gently parted her lips using his grip on her flanks as leverage to give him pass. They resisted for a moment, the subtle flesh pushing back against the soft tip of his tongue, almost kissing it as her lips clenched around the intruding invader.

He sucked in a deep lung-ful of air and held his breath, pushing on deeper past the outer lips and down through the soft, tight confines of Fl-this mare’s innermost sanctum. They pulsed and flexed around his muscled, slowly tightening and loosening, gradually adjusting to his presence and moulding itself around Zephyr’s tongue.

More fluids dribbled forth. A small trickle of sparkling nectar dabbed against the bristling hair of his chin. Her pussy lips tightened, the clitoral hood flinched, and the bulb of her clitoris shot out, nuzzling against the underside of his chin, before retracting back slick with her juices.

Fluttershy’s whole body shook. Her pussy tightened, spaying a fresh layer of her cum across Zephyr’s nose as she moaned. “Ooh—Oooh...”It was a little squeak, like candy, that tickled Zephyr’s ears as his tongue explored her interior.

Everything was soft and velvety, smooth and slick. It was hard to find anything that resisted his advances and what little did, trembled and retreated, away deeper down into her depths. Zephyr instinctively felt himself being drawn in, pressing his face all the way into her flank—his chin grinding against her crotch as he began to eat her out proper.

Fluttershy’s wings were twitching and shaking, her legs trembling and tense as her voice squeaked with heavy, sharp, pants. Every time he’d reach that hard nub, he’d give it a quick flick with the tip of his tongue. Her pussy would tremble, and it would snake away, further out of his reach.

He adjusted his position, his own breath picking up as he pulled his body in closer against the bed. Somewhere below, he could feel his own arousal calling to himself—something long and hard, urging him to rut this mare into oblivious. The end of his cockhead bumped against the underside of the bed, ready and dripping with arousal as Zephyr worked his tongue over her.

“Mhmmm...” He moaned. His eyes drifted shut, all his attention on the task at hoof. Several images passed through his mind, of different mares—some he’d known, other’s he’d wished he’d known, but no matter what, he always came back to the same image, that of Fluttershy, tied over this bed and begging him for release.

He pulled back, gasped for breath—she whimpered with disappointment, a sound that quickly turned into a scream as Zephyr returned in full force. Her drove his tongue deep into her crevice, bumping his chin against her clit just as it came out to meet him, and then as he draw out again, he caught the end of its wink between his lips and gave it a good long suck, drawing out every bit of pleasure there was to take.

.

~ ~ ~

.

Fluttershy was in utter bliss. Nothing could possibly compare to what she was feeling right now. Her eyes were covered, but her mind was awash with bright images, of sensations and stallions, of pleasure coursing through her body like no other she could have ever experienced.

Her body was sense, despite the bed’s best efforts, and the chains were beginning to dig into her hocks. Her head leaned back as she moaned out in another guttural squeal.

He was good, he was damn fucking good, and there she was going to ever let him stop. Her stomach clenched down against the invader, trying with all of its might to milk the stallion of all of his life-giving seed. It didn’t matter if it was a tongue, or a mouth, or even a hoof. Her body didn’t care. It wanted this. It needed it. There was nothing else more important in this world right now than the urge to have a foal pumped deep inside her.

The heat was rising—it had been growing non-stop since the first moment his tongue had touched her, and had only been building faster with every added movement. It was like the rising edge of a skyscraper, an oncoming cliff-edge just beyond her reach.

It was close. So close. Too close.

She attempted to rotate her hips, to egg him on just a little more, but the stallion held her firm under his strong hold. She was at the mercy of his tongue—that magnificent tongue and his mouth as it gently and roughly grazed against the sensitive flesh of her pussy’s lips.

She couldn’t help but whimper when he withdrew from behind her. That sensation of fullness was quickly overtaken by a helpless longing, and emptiness that nopony could hope to fill. “Mmmmhmm...” She groaned, pushing back in hopes he would return, but the chains and his hooves held strong. “Please...” she whispered with her ears splayed back. “D-Doctor Breeze, pl-please, I need yooouuuu-OOOOOOHHH”

His tongue slammed back into her pussy, stretching it full and grinding against her insides like a pleasure rod crafted by Princess of Lust herself. Something hard and rough grazed against her clit, adding a shock of hardened pleasure to the jolts that ran through her body, rocking her to her very core.

The skyscraper crumbled. The cliff-face rushed over her and slapped her across the face, and orgasm washed over her destroying everything in its wake as Fluttershy moaned out at the very tops of her lungs. “AAAAHHHH...” She squealed, her voice cracking, “Z-Zephyr Breeeze...”

The quakes subsided and the world shook around her as the throes of pleasure turned into a torrent of endorphins and lethargic bliss.

.

Zephyr held his face against her crotch, his lips clenched around Fluttershy’s love bud and his hooves tightened around her flanks as she violently rode out through the force of her orgasm. The mare shuddered and shook against the bed, and her fluids spurted out across his nose, painting it white with a glistening coating of clear liquid.

As her panting subsided, and her trembling lessened, Zephyr slowly extracted himself from the mound of trembling yellow fur and feathers.

He pushed away from the bench and stood to his full height. His wings were stretched to their limits and his face—dripping wet and sticky—was also glowing with a bright red sheen. His eyes were wide, staring, as he looked over the state of the mare with a mixture of pride and horror.

She looked like Fluttershy; his dear elder sister. She couldn’t be, he’d convinced himself it wasn’t, but there was no denying that the resemblance was uncanny, scary, almost. If anypony else were to look at her now, they’d say it was one and the same pony. His sister.

And he’d just brought her to the best orgasm of her life.

His sister.
