Anon slowly pushed himself up onto his elbows, his breath coming back to him one agonized puff after another - like he was a marathoner just starting to recover from completing a long run. Slowly, the blur of grey shapes and moving hair began to come into focus - and the dull sensation of his body began to sharpen.

Something wet, warm, and insistent was pressing against his length. Looking down his body, he saw the fierce emerald eyes of Limestone Pie, two orbs of deep green perched under her sharp silver hairline, staring straight at his half-erect cock… as she drew her tongue across his sloppy, cum-froth with long languid licks.

It was clear that she was enraptured with the taste of him… the way her eyes inspected his every fold and curve, looking for any missed splotches of ejaculate… then the way those same eyes ever-so-slightly rolled over in pleasure, savoring the flavors in her cheek before swallowing hungrily.

It made Anon’s heartthrob heavily, preparing to send a fresh course of blood to his half-hard tool for the benefit of the enthralled little rock-mare.

Pump after pump of hot blood coursed into his dick, quickly re-expanding it, inflating it like a hot flesh balloon in Lime’s hooves, until the tip began to bump against her wet snout.

She blinked, taking in the whole of the monstrous human cock, once again inflated to its full 8.5 inch length and considerable, firm thickness. It was cute, watching the usually edgy mare adorably size up the task in front of her, her eyes crossing over slightly as she tried to focus on the mammoth pole in front of her mouth opening slightly as if to gauge whether she would even be able to take all of Anon’s size into her.

Anon couldn’t help but throw in a jab.

“Wow Lime, you do know where that thing has been right?” Anon’s sudden quip caught Lime’s attention, and she followed the focus of the human’s eyes as he glanced over at her little sister, still mewling in delighted post-orgasmic slumber, a steady trickle of human cum pouring from her slightly gaping tailhole. “I mean I knew you were a real sh-”

“Ahem.” Cloudy Quartz’s throat clear, along with a flash of her eyes from her position next to her semi-conscious youngest daughter preempted Anon’s intended cursing.

It was like a thunderbolt striking the human… the cutting sharpness of that beautiful mother’s blue eyes - it wasn’t that he was afraid of her… it was something else. A mixture of respect and thrall… of obedience and caution… somehow she’d managed to tame him… and he didn’t mind.

But he was still Anon - maybe he couldn’t swear in her presence… but he could never stop trolling.

“Shh- I mean… I knew you had a potty-mouth, but I didn’t realize you liked the taste.”

Lime’s eyes sparkled with fury, and she stood up, walking forward until her hooves were planted on either side of his head, staring down at him with anger. “What did you say, punk?”

“I said - I think you like the taste of your sister’s butthole a little too much. Although I guess that would explain your breath.”

“Hey! My breath is fine. “ Her hooves pressed down into the bedspread on either side of the human’s grinning face. “And in case you weren’t paying attention, you moron, we took a potion that sterilizes everything down there and makes it smell like flowers.”

“Yeah, but how could that work, really?” Anon needled. “No potion can make a butt that delicious.”

Limestone’s features darkened briefly, another course of anger rippling through her face… before it turned into a wicked, mischievous smile.

“You know what, Anon?” Lime smugly replied, “You’re right.”

“I am?” Anon asked with surprise, not expecting her to crumble so easily under his trolling.

“Yep - I don’t think I’m ever going to be able to convince you just how effective Petunia’s potion is…” She leaned back as she spoke, starting to slowly turn around.

“Y-yeah?” Anon asked, uncertain… the mare was standing over him now, but with her rear hooves now planted on either side of his head. Staring up, he was looking right at Lime’s two teats - cute little average sized boobs wedged between her chiseled thighs… and those thighs were perfectly framing her plot.

Clearly displayed underneath her proudly flagged silver tail, Limestone’s pussy was already a swollen, drooling mess of a slit - her purplish-grey labia fattened with arousal, which could barely contain the darker and wetter inner lips, which had squeezed their way out of her vulva. Unlike her sister - Lime sported a big, fat clitoris - nearly the size of an Equestrian bit, and one that seemed to hang out in space in a constant state of wink - seemed to, that is, until Lime let loose an actual wink. The fat purple clit-head made its large size known then - sliding out of the mare’s pink interior, sending a gossamer strand of marecum shooting out as it did.

Just above that beautifully debauched cleft was Lime’s asshole. Unlike her little-sister, Lime sported fairly plump and large ring of ponut muscle - as Anon watched, it quivered with strength and lewdness beneath her wagging dock. Her tail was swishing back and forth like an excited puppy dog.

“...yeah, I’m not gonna be able to convince you with my words, Anon.” Limestone’s tail hiked up even higher, and she started to bend her rear knees, carefully looking back over her shoulder to gauge her landing point, “...you’re just gonna have to experience it yourself.”

“Eeeep!” Anon’s squeak was the last non-muffled thing to come out of his mouth, as the shadow of the muscular butt of Limestone Pie descended over him, moments before his entire face was buried in the sweaty, leaking, sexy flesh of Lime’s plot.

Hot. Wet. Musky.

No oxygen, only moments to breathe when the mare would grind herself a little too far forward or backward, giving his nose or his mouth a chance to suck in air before they were buried once again in Lime’s engorged genitalia.

It was rough and wild. She was using his face as a pillow - humping herself against his nose, his chin, his brow.

She was right, actually - the potion really did make her smell as fresh as flowers… her asshole, anyway. The butter-rich lemon-scent of her marehood couldn’t be masked by her fragrant tailhole, as she drooled the equally musky nectar in sticky strands all over his chin and neck.

It was a strange mix of excitement and fear - the survival instinct kicking in when one of LIme’s grinding humps would last a little too long - making Anon try to breathe in precious oxygen through an orifice currently embedded in her steamy plot, making his lungs burn and ache with need.

And he wasn’t the only needy one.

“Mmmm, yeah… betcha like my ass, now, huh punk:?” Lime groaned, arching her back upward to push even more weight onto Anon’s face.

Anon felt his nose slip into the slick, slippery confines of Lime’s cunt - the sharp tip of his snoot embedding itself almost an inch into her body - incredibly, he could feel her marehood grasping and clenching at him. Wanting to take somewhat more of an active role beyond ‘humpable pillow’, Anon hooked his hands over Lime’s hip bones, pulling her even harder into his own face…

Then he opened his mouth as wide as it would go, extending his tongue, to its utmost, reaching forward with it to tickle the upper bits of Lime’s squishy vulva. The citrus-tang of her delectable nectar made his tastebuds burst with delight, as he explored the different bumps and folds of her secret lips - little nubs and ridges that he could only assume were the upper cleft of her vaginal opening, a much tinier hole that had to be her urethra, little nubs that could be Bartholin’s glands… until finally, he found that fat throbbing bulb of pleasure.

“Oh… b-buck!” As soon as he made contact, only just able to touch the sensitive nub of nerve endings because his nose was still jammed in the lower part of Lime’s cunt, the mare groaned from deep in her belly, slumping forward to give the human a better angle at her clitoris. “Yeah, that’s it… right there... Lick it like a little puppy-dog!”

Anon obliged, lapping and teasing the thumb-tip sized clit - using his newfound reach to slip under her clitoral hood, delicately separating the throbbing purple clit-head from the prepuce of blood-fattened skin, sliding around the base, testing new areas that had likely never been touched before - buried so deep in such secret spots.

“MMMmmHNNGGGH!” Lime’s grunt was louder and more insistent, and she once again back mashing her hips down and back into Anon’s face, pushing off against the human’s knees for even more leverage to really mash her drooling holes against his head - driving him down into an indentation on the now soaked bedspread.

It was all darkness and sensation for Anon.

With a tight, generously-sized, rock-hard pony asscheek on either side of his head… his mouth and nose buried in earth-pony cunt… and a sweaty, hot pony-ponut practically suction-cupped to his forehead… all he had was the sensations of touch, and the sound of a pounding heartbeat in his ears - whether it was his or Lime’s, he couldn’t tell. This had a tendency to heighten one’s senses - losing sight and sound meant that taste, touch, and smell became so much more poignant.

He could feel, for instance, the wispy touch of hair tickling the tip of his throbbing, fully erect cock. Like a dancing, naughty paintbrush tickling at him. Sometimes it would be followed by a soft fur-cushioned thwap against a strangely featured surface… Anon correctly guessed that his massive pillar was millimeters from Limestone’s face, just underneath her straight-edged brow, and every time the gasping mare humped particularly violently, she would bounce against his shaft.

Flexing his abdominal muscles, Anon managed to make his cock jerk and flex, playfully smacking it against the groaning mare again and again.

“MMnnngh... B-bucking annoying… th-thing…” Lime groaned.

A moment later, Anon felt the tip of his cock slip into something hot, wet, and slimy. Once he felt a swirling, inexperienced snake of muscle darting around his head, lapping eagerly at the pre coming out of his slit… he knew that Lime had taken him into his mouth.

He had to reward her for that.

Pursing his lips, Anon managed to catch the grumpy mare’s clitoris during the course of one of its winking extensions, suckling on it like he was trying to draw a thick milkshake through a tiny straw. He could feel the resistance of the elastic tissue as it tried to pull the bulb back into its fleshy sanctuary - but he wasn’t about to let it do that.

“MMMMMMNG!” A muffled groan came from Lime’s chest, rumbling through Anon’s own abdomen where she had pressed her fluffy chest in order to get more reach and thereby engulf more of his human manhood. Her tongue had stopped swirling and thrashing inexpertly around his head - a clear indication that she was being overwhelmed by sensation and was not able to continue focusing on her first fellatio.

Anon sucked harder, drawing more of the fat, quivering, clit-head into his mouth, keeping it trapped in a state of permanent extension - a never-ending wink of pure ecstasy, combined with a potent suckling suction and a darting, massaging, aggressive tongue.

Lime never stood a chance.

“MMNNGHHHHHh….. Mmmm…. Mm…..m…” The mare’s gasping moans rumbled around Anon’s dick, her exhortations coming in bursts that coincided with the powerful spasms of her orgasm. Each time she came, Anon felt her drawback and forth, her cunt milking at his nose insistently, the clit in his sucking lips going wild with tension and release.

And the spray.

It was almost like he was being waterboarded - thick, juicy, splattering splashes of sloshing marecum rushing across his face, a sticky natural lubricant that made it hard not to inhale the lime-scented aphrodisia directly into his respiratory system.

Spasm after spasm racked her - drained her - literally and figuratively - as the usually tense and ferocious mare emptied onto him. And still, he didn’t release her - didn’t let her clit go…

Not until she completely surrendered, the moment when she gave in totally, her muscles going atonal, her body relaxing and pooling over him like a bundle of melted bones and skin and fur… her head slumping on his cock supported only by the prodding of his cockhead against the roof of her mouth.

Only then did he finally stop sucking. But her clit had already given up - it remained extended, throbbing an exhausted, completely out of strength to retract and recuperate. Anon had managed to go from being completely dominated underneath this young mare, to conquering her. Lime had a lot to learn from her mother.

But now he was going to own her.

Scooping up a good tongue-ful of mare-juice with his tongue, Anon used his hands to shift the limp, pleasure-paralyzed rock farmer’s bottom ever so slightly, repositioning his tongue so that he would have better access to a… lower part of her body.

Anon blinked his eyes clear of fluid, taking in the first light he’d seen for minutes as he stared at the pony plot mere inches from his eyes.

It was time to find out if Petunia’s potion really did work as advertised.

Lime’s delicious tailhole was right off his nose, a tight, but powerful ring of muscle that quivered and shook with the small aftershocks of Lime’s powerful orgasm. He could just see the taboo bright pink of Limestone’s insides when the rosebud would clench and unclench, hinting at what was within.

It certainly smelled amazing - like fresh spring flowers in a meadow, a blossom he might actually stop to sniff on a summer hike. But Anon was still suspicious - he’d never eaten… ass before.

But there was a first time for everything.

His tongue slid around the fat muscular ring, the strange texture of slick skin tantalizingly alien to him. The bud on his tongue was a living, breathing thing - quivering and twitching with Lime’s heartbeat, reacting to his delicate encircling probe. Once he’d made one full circle, he slid his tongue up and over the ridge of her ponut, delicately tracing down one of the wrinkles of her dark-gray starfish… until he reached its center.

The flavor was neutral - a mixture of the petunia-like potion and the sweaty-musk from Lime’s marehood, but the heat was something entirely different. Like a magma tube at the bottom of the ocean, the tight pinhole at the center of Lime’s rosebud leaked pure, boiling heat.

Curling his tongue into a thinner shape, Anon plunged forward - poking into the mare’s anus.

“MNNNFFF….” Lime’s cock-gagged grunt rumbled through his organ as he pierced her.

The sphincter gripped and clenched on the invader, clearly unsure and unfamiliar with having objects going through it in the wrong direction, but the clean taste and exciting reactions his first probing dip elicited only inspired Anon to drive in even further.

Gripping Lime’s buttocks with his hands even more fiercely, he pulled the solid mare as hard against his face as he could, trying to drive every bit of his available tongue into her rear. It wasn’t easy - the powerful coiled muscles in her bottom were pushing against him, trying to expel his snaking, thrashing invader from her taboo garden… but with the help of his arms, he was able to persist.

“Mmllrkk… Gglllrkk…!” Strange choking, swallowing sounds were coming from his groin. Lime had accidentally ingested a good few inches of his behemoth when she’d likely meant to shout out in alarm at the sensation of human-tongue up her butt… Anon could feel the inexperienced mare’s esophagus clenching and grasping around his fattened head.

He moved his tongue left and right, up and down… the puffy and muscular ring of flesh resisting his movements- it felt as if he were trying to punch and expand a hole in a marshmallow made out of dense taffy.

But damn was it fun to feel the mare’s reaction to his movements. She couldn’t help herself - grinding her ass into his tongue like an animal, as she moaned like a whorse around his cock - slobber splattering down into his lap and all over his balls.

The once fearsome Lime was like a toy in his hands… and on his tongue.

“MMM! MMMGN! Mmmmm….”

Anon felt her body shudder, felt her asshole clench down hard… a spill of juice splattering over his neck and collarbone as Lime’s pussy gushed a fresh dollop of lubrication - clearly a desperate offering for a stallion-cock that wasn’t actually penetrating her. The poor mare’s body was in such a state of confusion - a needy and desperate piece of malfunctioning biological hardware.

Anon slid his right hand off of Lime’s hip bone, carefully maneuvering it underneath her plot, casually tracing his fingers over her hardened nipples, like they belonged to him… before sliding his middle finger up and against the spot just under his chin, beneath where he was still tongue-fucking the mare’s asshole… lining up the tip of his digit with her swollen vaginal opening.

Instantly, his finger was marinated in Lime’s honey, still pouring from her in dripping strands. He didn’t even need to push his finger in, either… Lime humped herself back onto the middle finger in the throes of her grinding and reckless abandon… his tip slid in easily.

It wasn’t as tight as her ass but it was just as needy. Her greedy cunt-muscles swirled and milked at the new penetration, drawing more and more of his finger in with each of her plaintive backward thrusts… until he was at the second knuckle.

“MMfff! MFFF!” Lime’s head began to bob faster on his length - slamming the fat head of Anon’s penis against the narrow bottleneck of her throat. And that wasn’t the only thing that had met impassable resistance…

Anon could feel his digit pressing against some strange, spongey barrier inside Lime. He’d fingered plenty of ponies over his years in Equestria - but this was something new… it could only be…

So she really wasn’t kidding about being a virgin.

Anon grinned internally. There was something undeniably a bit sexy about being the furious mare’s first, and he wanted to make sure her first fingerbang would be extremely memorable.

Sliding his digit deeper wasn’t in the question now… but adding one or two more certainly was.

First his index joined his foundering finger, then on the very next stroke, his ring finger… And what had once been a somewhat tight but needy pussy, quickly became a strained, stretched, stuffed marehood. The swell of Lime’s inner and outer labia with blood mashed Anon’s digits together, as delicate inner pink skin stretched to accommodate the human’s invasion.

Squeaking mewls were all that Lime could respond with at this point… any semblance of trying to speak through her cock-stuffed throat given up entirely to animalistic grunts. Her whole body was constantly trembling now, an excited rumble that sent the gray mare’s sweat and juices flinging off of her as she wiggled and writhed on the first two inches of the human’s fingers.

Her tail was wagging up a storm, too.

It was stuck way up in the air, of course, the wispy hairs flashing about like some elaborate feather duster - but it also waved from left to right, something whacking Anon’s in the forehead, or providing him with a cool breeze as some modicum of relief from the hot, sticky, volcano of lust he was buried in.

On one particular thwack, something came back to Anon… something Pinkie had mentioned to him before she’d darted off like a banshee… her dock… remember her dock.

Anon brought his left hand from its perch, losing some of the purchase he held against Lime’s butt, which let her thrashing and grinding become even more violent, as the mare bounced her ass with intensity against the human’s face and fingers, painfully knocking into his nose and head. It was no easy task to grab hold of the mare, but he somehow managed, taking hold of her tail with his left hand, pinning the excited dock.

Anon composed himself - taking a brief moment to appreciate where he was: knuckle deep… tongue deep in Limestone Pie, a mare who had never had anything for him except a cruel word and a bitter send-off. But who was now a kitten in his grasp, her maidenhood literally at his fingertips, and her weak spot a heartbeat away.

Could he really do this to her?

Memories of the mare calling him a punk, pushing him into the mud, throwing rocks at him (though Pinkie claimed it was part of the traditional ‘rockball’ fight instead of snowball fights), and screaming bloody murder at him every time he looked at her big dumb boulder.

Yes he absolutely could.

In a coordinated movement, Anon pressed the fingers of his right hand deeper, and jammed his left thumb against the delicate patch of skin under Lime’s tail.

He felt the delicately give of supple, spongy flesh as his digits took her virginity, and felt a powerful throbbing pulse from the bundle of nerves under Lime’s tail.

Then he felt the rock-farming mare explode.

…

It was like she’d been hit with a cattle prod - each and every one of the gray muscles jerking to full tension in the same instant. With his tongue still buried deep in Lime’s tailhole, for a brief moment Anon wondered if it was possible for a ponut to snip right through a tongue… or for a cunt-squeeze to crush three fingers. Earth-pony strength really was terrifying.

Lime’s spine arched as well, her strong back tensing under her orgasm, the motion causing the mare to jerk her head off of Anon’s dick, throwing her mane wildly back, leaving only a long thin strand of saliva connecting her gaping tongue-lolled mouth with Anon’s thick cockhead. She’d thrown her head so far back Anon could almost see her eyes staring back at him for a moment - wild, heart-shaped pupils that sparkled and danced with lust-craze… another mare broken by Anon.

There was no controlling the mare’s bottom anymore, which slammed up and down with impunity, humping itself like mad on his fingers. The human could feel the tremendous winks crushing his fingers in powerful convulsions, sending her fat-purple clit shooting in and out with copious gushes of mare-juice as it throbbed the lovebud against the back of his hand. Her asshole was doing much the same thing - pushing and pulling against the strange foreign invader inside of it, unsure whether it wanted more of Anon’s tongue in it… or all of it…

And where Anon had heard some mares have loud, heavy, ceiling rumbling orgasms… he’d never heard one quite so… vocal.

“OH FUCK, FUCK, FUCK YES.” Lime brayed, almost whinnying before her words began to cascade into one another. “YES, YES, YESYESYESGRABMYFUCKINGDOCK… ANON! ANON! NONNYNONNYNONNY YANK MY TAIL, RUB IT THERETHERETHERETHERE!”

Anon did as he was instructed, clenching the mare’s dock and pressing his thumb deeper into the soft indent he’d found, which clearly was the ‘crazy-mare on/off switch’ for Limestone Pie.

“YOU’RESOFUCKINGGOODNONNY… I WANNA WANNA I WANNA IT SO BAAAAAD.”

Disturbingly, Anon noticed that the mare’s usually straightlaced and sharp hair was starting to get quite… curly, random… volumized… poofy.

The silver sheen took on a more colorful tint… was this the opposite of the ‘sad Pinkamena Diane Pie effect’?

Still gushing in every way possible, Lime pronked up to all fours, pulling Anon up to his knees as she did so, jerking his tongue out of her butt, and his fingers out of her marehood, as the human desperately hung onto her dock for dear life.

Anon suddenly found himself on his knees, cock rock hard and ready to go, and right in front of him, with her now poofy and Pinkie-like tail clenched in his hand, was Limestone PIe: sticking her ass up in the air - presenting her needy, drooling marecunt to him.

She looked over her shoulder, fixing him in the eyes. Anon couldn’t help but notice how much Lime looked like her younger, pinker sister in the midst of a cupcake-induced sugar rush. The farmer’s eyes were giant wingding-style hearts, her face was plastered with a dopey-drooling ear-to-ear smile.

“A-A-anon…” Lime grinned, shaking with happiness. “I l-love to see you SMILE… while bucking me senseless!” She wiggled her ass in the air, with a ferocity and intensity that Anon would have deemed impossible for anyone without Pinkie’s fourth-wall-breaking ability.

“Now…” Lime’s eyes glazed over as she started to push backward, bringing the tip of Anon’s swollen cock and her plump, drooling snatch close enough that Anon could feel the steam rising off of her, “...you’re gonna gimme plow my rock fields with that big, yummy, human co-”

Anon felt a sharp sting in his left hand, making him wince and release the thrashing and crazy dock. A sharp strike, expertly delivered by Cloudy Quartz, just in time.

Almost as soon as he released his hand, the bizarre changes in Lime faded away. Right before his very eyes, Anon watched as the color that had been entering her coat and mane drained down to her hooves and faded, as her tail hair straightened and fell to the floor… her curly poofy bangs deflating and returning to their sharp bang-line, as if the force of gravity on Lime’s hair had just increased ten-fold. The mare’s bouncy, energetic twitches melted into exhausted nothingness, and the corners of her crazy smile dropped instantly, leaving her mouth a gasping, tongue-out mess as the mare collapsed to the bedspread, panting as hard as if she’d just finished a marathon…

About the only thing that stayed the same were Lime’s eyes… still heart-shaped (though smaller_ irises that cavorted wildly under her sweaty brow.

“Mmnnno...no… f-fair mom…” Lime moaned, struggling to lift her exhausted head up from the faceplant she’d just done to look at her mother. “I… w-was… I w-wanted… Anon to be my….”

“Shh… shh…” Cloudy comforted, brushing her daughter’s sweaty mane comfortingly. “He will, he will… don’t worry.”

“I… don’t… w-wanna become a wizard.” Lime gasped out, her eyelids drooping lazily, one more than the other.

“A wizard?” Cloudy craned her neck back, looking at her daughter with a wry grin. “Now you’re being even more ridiculous than when you were getting all ‘Pinkish’. Everypony knows that if you got magical powers from being untouched at thirty, you’d have a lot more alicorns running about. It’s on old mare’s tale, Lime.”

But lime had already drifted into a stupor-filled, post-orgasmic sleep, not far from her baby-sister’s nap in a similar nest of pillows.

Cloudy sighed, patting her eldest’s head lovingly, before turning away from her and looking at Anon.

“I apologize for striking you, Anonymous... but I do believe we had an arrangement.” Cloudy grinned. Turning toward the human slowly and with a creeping smile on her face. She reached up, taking her glasses carefully off of her face.

“You were quite right in pointing out to me that a head mare’s responsibility to her herd is to go first.” She placed the spectacles into an eyeglasses case, snapping the lid shut as she did so.

“And with such a wild, uncouth stud as you, and what you’ve done to my little girls…” Cloudy removed her collar and necklace, also placing them delicately on her nightstand as if she were preparing for nothing more than to go to sleep on a normal night.

Anon could only gulp with fear at the dominant older mare as she eyed him down.

“I can see that before I let you have my girls... it will be my job…” Cloudy pulled the hairpin from her mane, letting the whole of her tight and well-maintained bun explode out into the wild cacophony of green, tousled strands that Anon had seen when he’d shouted his pick-up line at her before. Her big blue eyes were filled with hunger - confidence - and passion… like a lion about to chow down on a wounded gazelle.

He was screwed.

“...my job… to break you.”
