Creating the uberponer

Fuck. Fuck! FUUUCK!

“WHAT!?” I stood up. “What did I just drink, Aryanne?” I began to notice just how tingly all my muscles were feeling, little pinpricks of energy surging down each of my nerves, a cold sweat breaking out over me.

“A magical transformation potion, zat vill turn you from a man into a pony… into a superior race!” Aryanne chuckled as if this were the most obvious answer in the world.

Oh, fuck fuck fuck fuck fuck. She’s absolutely fucking crazy and I drank some weird-ass poison she gave me! My hands reached for the phone in my pants pocket, discarded on the ground, but the shaking in my arms was so bad now I could barely move them.

“H-help… I’m… I’m gonna die.” I choked out, feeling a sudden warmth spreading from deep inside my gut, my throat constricting as my eyes began to blur.

“No no no! Like I said, ze likelihood of fatality is quite low, at least for ponies like me. A natural human, it eez a bit higher, ein out of drei, Franziska says. But zere are plenty of humans! Do not vorry.”

A sickening shudder wracked my body, and I suddenly found myself unable to move any muscle. It was like I was trapped behind my eyes, a silent prisoner to whatever poison had paralyzed my system. That’s when, to my surprise, my body actually did begin to change. I could feel a burning heat flush out from my gut, and the first place it’d spilled to, likely because of all the blood that had been rushing there moments earlier, was my groin.

The very familiar sight of my male pride suddenly began to morph before my very eyes. First, a swelling throb that made it strain against the very confines of the pink skin. Then, that pinkness began to grow darker, a nasty shade of purple. Combined with the swelling, I looked like I was suffering the consequence of having tried to make love to a wasp’s nest.

Then I suddenly felt my testicles bulge, first the left, then the right. Popping from their normal egg-size to that of an orange. My poor sack felt like it was about to tear, as the normally wrinkly skin was pulled as taut as the surface of a balloon in its attempt to contain the massive sexual organs within. Half a moment later, the sack descended, falling halfway to my knee and dangling off the edge of Aryanne’s bed as the skin turned a striking shade of midnight black.

I barely had time to marvel at my huge new coin-purse, as a powerful throb made my manhood strain upwards… and outwards.

To my shock, each beat of my heart was adding inches to my length, as my member grew impossibly, pump by pump, the gravity of its new bulk, and the leverage of its new length causing it to dip toward the floor.

The darkening purplish-black thing had to be over a foot long now!

It was getting thicker too, new veins bulging and boiling out of its surface, including a small wrinkle of flesh just under the head, at first just a little bump, but one that quickly stiffened and raised onto what I could only describe as a ring of meat.

“Ohn… f-fuck…” The words felt strange in my mouth like my tongue wasn’t shaped the right way. But I had to utter it — the moment that ring finished forming, my already massive genitals began to spill outwards.

Like a waterfall of cockflesh, the now black penis-meat poured from under the new medial ring that had appeared on my shaft… three, four, five… eight inches of new shaft as my huge new beast drooped toward the floor, well past my knees.

And it was growing in girth as much as it was in length. I’d hear the phrase ‘a baby’s arm holding an apple’ and laughed in disbelief, but this was more like a man’s arm! Closer to my body, the base of the throbbing cock required to maintain such a fearsome length was quickly approaching trunk-like proportions.

“Mein Celestia, you vill be hung,” Aryanne half-whispered, her eyes twinkling with excitement as she watched my penile transformation. Her eyes flashed even wider as my mushroom-shaped tip throbbed with a few last pulsing throbs, flattening and thickening to the size of a fist-wide saucer plate, complete with knobby protuberances and a urethral opening as large as a milkshake-straw. “Very hung.” I thought I might have noticed her biting her lower lip.

I didn’t have time to think about just how excessive a size queen Aryanne truly was: pain I could only describe as searing filled my mind with white-hot stabs of agony. It was like every bone in my body was breaking and re-knitting simultaneously. I could feel my joints cracking and crushing, some breaking backward, others binding together.

My organs were a hot stew of churning heat like someone had stuck a blender into my thoracic cavity and hit ‘puree’.

I could hear my own skull cracking. Not a sound I would recommend for anyone’s playlist.

At some point, whatever bundle of neurons was responsible for consciousness and sensation mercifully shorted out.

I welcomed the tunnel of blackness and certain death as it crept up from the corners of my eyes… the last thing I could see was Aryanne’s face soaring to what I could only describe as euphoric heights.

My eyes snapped open again.

Blackness, still. Only sensation.

Everything was wrong.

All the feelings in my body were totally off, every movement and sensation a new neural pathway, hitherto unused. It was like the entire wiring of my brain had been returned to factory default settings…

And I couldn’t move my arms or legs. My knees felt all wrong, and for some reason, my fingers felt numb, unresponsive, like they weren’t even there. But at least I could tell that I was tied up.

“Ah! You are alive, Aaron?” Aryanne’s voice echoed through my ears. “Thank ze Goddess, I von’t have to burn troo anuzzer vun! Ze forms I haff to fill out, you vould not believe!”

So I guess I wasn’t dead. I wasn’t sure whether or not to be happy yet.

“Ah! Vait just a moment so zat I may properly introduce meinself!!” I felt her fingers scrambling at the back of my head, and suddenly I was flooded with bright, blinding light.

I wasn’t in her room anymore.

“Mmmf… mnngh…” I tried to say something, but there was something jammed in my mouth. A gag. I was tied to a bed, lying on my back which felt uncomfortable against a spine that was anything but like my own, each of my limbs pulling me spread eagle, one arm toward each of the corners of the comfortable mattress.

“Mein apologies for ze restraints, Aaron,” Aryanne chirped, striding in front of me. I noticed her dirndl had been replaced by a uniform that looked like it was right out of a cosplay convention. I couldn’t place the origins of the grey and black jacket with silver brocade in my addled state, but I had to admit the thing looked as stylish as if it were designed by Hugo Boss. “I have only just Gotten you back to Eqvestria. I haff not even returned to mein true form. I did not vant you runningk off and hurting yourself.”

My eyes blinked, the lids felt heavier, different. I noticed that a big tuft of blonde hair was hanging over my right eye. But I had brown hair...

The room seemed familiar, though I’d never seen it before. The same bed, the same cleanliness, the same posters and paraphernalia hinting at somebody a little too obsessed with early 20th century German history.

Aryanne must have noticed my wandering eyes. “Ah yes, I apologize for zat, too. I vas supposed to bring you straight to headquarters upon successful conversion...” The blonde-haired girl blushed, looking ashamedly down at the floor, “...and yet I haff brought you to mein Eqvestrian home, vhy is zat?”

She looked up at me, cheeks puffing out cutely, eyes almost dewy with admiration.

“I… I vas not expecting you to turn out zo… zo gutaussehend — so handsome.” She scowled, playing with her hair. “And zis damn human body. It has no estral zycles! I feel like I am in heat! It is making me vant to do all sorts of immoral things vith you! Scheiße!”

She tossed her head back in frustration.

“Mmmf!” The only reply I could make in the situation.

“You do not believe me? One moment.” Aryanne stood up and strode to a nearby full-length vanity mirror, taking it in both hands and pulling it over to the bed. That’s when I saw something that made me scream as much as was possible through the sock stuffed in my mouth as I thrashed vainly against my bonds.

It was me.

As a pony.

I was just as large, if not larger than I had been as a man, but what had once been pink skin and human limbs had been entirely replaced with something totally alien.

Short, white fur covered my entire body, from my muscular barrel chest, over my powerful flanks, and up my strong stallion-ly neck. A shimmering waterfall of golden mane spilled from my new pony-head, which was only interrupted by a large spiraling horn protuberance.

A… unicorn!?

The way that my eyes stretched wider with shock was the only confirmation that those deep blue pools had replaced what had been my former green irises. The kicking struggle that followed, sending my new golden tail flashing up into the air was the final nail in the coffin. Those hoofed, powerful limbs were indeed my own.

I was a blonde-haired, blue-eyed unicorn.

“An über-poner!” Aryanne clapped with delight. “A complete dream-boat. I never vould haff guessed vith how ugly you vere as a human, but Aaron, as a pony mein heart is’ aflutter.” She sat down on the bed next to me, her hand reaching out to brush the tail hairs away from my side, revealing some kind of tattoo that she’d applied to my flank - a blue six-pointed Star of David. “And such a wunderbar cutie-mark! Aaron… I sink your people on Earth, ze… ‘Jews’? I think zey are ze chosen people, ze master-race of your world! And ve need zem here, vith ze unicorns, in Eqvestria!”

Aryanne slid next to me, her uniformed butt bumping against me as she leaned in close. Her arms wrapped underneath and around my barrel, as she squeezed me tight in a hug as if she’d just won me as a prize at the state fair. Her head snuggled into the nape of my neck, and I could feel her nostrils tickling my fur as she drew in a deep breath, smelling me.

“Oh Aaron, forgive me. I vant to do zings to you, zat no upstanding unmarried mare should ever, ever do.” She giggled, a finger twirling the tuft of fur on my chest, as she gazed dreamily into my face. She leaned in closer, and closer, her soft lips inching up and then gently caressing my new nose, as light as the touch of a butterfly landing on a flower.

“But, I know you are a gut stallion,” Aryanne cooed, sliding her legs onto the bed so she was lying next to me, one hand propping her head up and the other making circles on my belly, going lower and lower. She bit her lip as a tuft of hair fell across her face, and craned her neck up to my left ear. I could feel the small trace of a wet tongue-tip darting along the sensitive inner-part of my ear, making it flick involuntarily before she followed with a husky whisper. “I know you vill marry me and fill me vith your foals, to make me an honest mare.”

As she said this, her lower hand took hold of me.

And by me, I mean the new, very horse-like package I was sporting down below.

Her playful hand briefly cupped and rubbed my melon-sized balls, before taking a firm grip of the big, floppy sheath of black skin that contrasted so starkly against my white belly.

“Mmnngh…!” I groaned in pleasure. Her hand felt amazing.

My new bits began to spill into her hand, as my erection emerged from the sheath with each beat of my pounding stallion heart.

“Oh, Aaron. Oh, mein Gott!” Aryanne whispered in marvel as I grew more and more in her squeezing hand. “You are… so big. Vat a stallion. My stallion. My stud.” Her words were almost like moans as I finished growing.

My huge, pulsing horsecock reached up to beyond my ribcage easily a full twenty inches. Hung like a horse was more than just an expression for me, now. Aryanne’s hand looked tiny, her fingers not even making it halfway around the thick log of flesh as it throbbed in her grasp.

I could scarcely believe the leg-thick base was real if I wasn’t also feeling it. It’s hard to describe, having a penis that size — having sensations of fullness and pleasure that would usually only be distributed over something about the size of your hand now amplified and stretched across something the length and breadth of your entire arm. Aryanne’s cloying fingers, tentatively exploring the underside of my head weren’t helping either.

“Mmmnnnfgh!” I groaned again into the gag, as I felt a familiar pulse deep in my loins surge up. It felt like I was cumming.

My thick stallionhood slapped up and down against my belly, then emitted three heavy spurts of clear, thick essence against my upper belly. The surge of pleasure felt as potent as an actual orgasmic release, but it had only been my new body emitting some pre-ejaculate!

“Oh Aaron, mein leibe…” Aryanne giggled, quickly cupping her hand to catch the last spurt of stallion-nectar, the drenching splatter completely filling and soaking her digits. “Vas zat for me?”

I quickly noticed the smell. My smell.

Musky and heavy, dripping with masculinity and an odor of oak, cigars, and brandy. They say that humans have become inured to pheromones over the course of generations of evolution.

Not ponies.

And not ponies transformed into humans.

Aryanne lifted her dripping fingers to her cute, button nose and inhaled them, smelling them with a full draw of her breath and a contented sigh that followed right afterward.

“Mmm… oh, scheiße… I love ze vay you smell.” She brought one of her drenched fingers into her mouth, savoring the taste of me.

Despite how freaked the fuck out I was, my brain forced me to swallow in reaction to just how damn hot the sight was. Long past the point of mortal terror, I’d reverted to thinking with my other head — the enormous, flared monster still seeping softly onto the mattress.

“But I mustn't vaste your gift, mein leibe.” Aryanne slid her hand back to my twitching head, her hand now well-lubricated. She began to slowly and clumsily pump the first few inches of my member, her fingers swirling like a vortex of sensation around the nooks and crannies of my new, larger glans.

My cock jumped up in her hands, straining off my chest as blood surged into the huge stallion-sausage, thickening it further.

“Mein Celestia, Aaron!” Aryanne gasped, bringing her other hand to help her barely wrap one whole ring of grasping girl-fingers around my cock. “You vould put even ze barbaric zebra savages to shame, so fat and long and… powerful.”

Her hands began working themselves up and down my length, coating my obsidian length with the fountain-like trickle of pre-cum burbling from my pulsing tip. My hips surged up off the bed in delighted agony as her fingers bumped over my ring, as she worked all the way down to the bottom of my fat stallionhood, her hands losing the ability to maintain even a two-handed grip at the ultimate girth of my hilt.

“Scheiße, zis vill break an ordinary mare, Aaron,” Aryanne muttered with wonder, her eyes transfixed on my new equipment, before they flicked back to my face, and twinkled with a naughty glint. “But I am not an ordinary mare.”

Before I even knew what was happening, Aryanne’s head ducked down and kissed my cockhead. The butterfly kiss that had graced my nose was gone, replaced with a suckling, smoothing smooch that let her tongue dance across my new urethral opening.

Showers of electric sensation danced across my eyes, sparks of pure pleasure making me see spots as her tongue raced back and forth over me. I felt her try to push more of my huge, fist-sized flare into her mouth, only for it to quickly catch on her teeth.

“Bwah…” Aryanne popped her mouth off briefly, looking back at me with an apologetic glance. “Sorry Aaron, I can’t fit you in zis small, human mouth… but I don’t sink even my pony mouth could fit zis.” She giggled and began to lick me like an ice cream cone, her hands pumping faster and faster.

In some moment of twisted humor, I’d imagined an ice cream shop, selling different flavors of cock, with a large gallon tub labeled with my name on it — all the while I shivered with delight.

“You taste so gut…” She groaned, pumping the big black shaft and lapping at me.

I don’t know what it was, the sensation of her pumping, insistent grip, the darting licks of her daring, greedy tongue or the intensely erotic vision of a blue-eyed, blonde-haired, beauty of a girl blowing a massive horse-cock…

But it was too much.

I felt my new, heavy balls clench and shoot up to my abdomen; a painful throb more powerful than any yet raced down my shaft, like the first pulse when you turn on a garden hose. The incredibly alien and unique feel of my cockhead blossoming, flaring into a wide, stiff saucer-flat plate of pure masculine rigidity was stunning.

And then I erupted.

I don’t know how to describe it.

It was like orgasming as a human… if a single spurt lasted as long as taking a long leak.

That incredible feeling of jerking, clenching release… but just so much longer… and so much more.

The eruption of steaming horse-semen was a welcome surprise to Aryanne. Moments into my first steaming rope-thick blast, the girl’s cheeks were already full, and she was forced to pull her face from the erupting geyser. Through the haze of my orgasm, I could see her swallow what she had managed to catch, her eyes shimmering and rolling with delight.

“MNnnnngh!” I groaned, as my second burst began in earnest, shooting a white arc that slung high into the air, splattering back down on my chest with heavy plops of glue-thick weight.

“Scheiße!” Aryanne squealed, moving quickly out of the blast zone.

All I know is that I shut my eyes with the straining pleasure of the conclusion of my second shot, and by the time I had opened them again, Aryanne had straddled me.

The girl looked down at me with desperation, her long hair hanging from either side of her head. She’d hastily torn down her leggings so they were bunched around her knees, and just as my cock began to jerk and spurt its third heavy dollop, she plopped her athletic bottom onto my belly…

Pinning my mid-shaft against her bare pussy.

Even through the surge of orgasmic overload, I could feel the sticky, hot press of her pink human pussy-lips against the ridge-thick slickness of my horsecock. Her vagina was just as cute as she was, a small tuft of now-moist blonde fur nestled above a pair of slender, tight lips that were sliding up my spurting shaft.

“Nein, nein, nein!” Aryanne groaned, leaning herself more onto my cock. I could see her little clitoris peeking out from its hood, the contrast of colors as the hot-pink button mashed against the dark black of my stallionhood striking. “Ve are vasting it!”

My spurts were firing across both of us now, the heavy dollops splattering against her cotton jacket, soaking it as thoroughly as if she’d been the target of some obscene super-soaker filled with tapioca pudding. But still, she kept sliding up, not minding as blast after blast of my steaming spunk splattered against her belly, chest, chin, and face. In fact, she seemed to like it.

Her diminutive pussy finally reached my spurting flare, the wet press of her boiling labia as she slid over my fattened, knobby glans making me realize why a friend back on Earth had once told me that a pussyjob was superior to actual sex.

But it was all a pipe-dream.

Aryanne’s hurried grind had been doomed from the start, the size of my new equipment was comical compared to her human anatomy and Aryanne could only mewl with frustration as my eight and final pulsing release splattered into her steaming furrow, the massive dome of my stallionhood as unlikely to enter her as a cantaloupe might be pushed into a garden hose.

“Mmm… mmmf… mnngh…” My groans from behind the gag were the ending notes to the soundtrack of my orgasm, all while Aryanne desperately pressed herself against me, grinding out the last few burbling pulses of white spunk.

“Scheiße, Aaron… it vill never fit.” She swore under her breath, clicking her teeth. Steaming tendrils of evaporating musk came off of her soaked clothes, body, hair. She was drenched in eau de musk. And she was frustrated.

“Zis damn body, I’m sure it is in heat!” She groaned, reaching down to cup her swollen womanhood, covered in sticky spunk. “You haff no idea how badly I vant you inside me, mein leibe. I vant to bear your foals… our foals, so badly…” One hand went back and cupped my twitching sack, “I vant you to fill me. It is like mein first estrus! But zis damn body, too small…”

Then her eyes flashed, brightening, and she turned to a now-familiar looking flask on her bedstand.

“Ah… but it is time for you to see me as ze mare I really am.”
