Man into Stallion Transformation Story

You didn't go to the city library too often, but sometimes it was a necessity. Not to mention the fact that some books were actually decently interesting to at least check out at the library, without the need to borrow them.

You examined your most favourite literature genres for a few moments. Going from shelves to shelves and exploring rows of them, looking for interesting titles.

With your attention on the shelves as you walked, you failed to notice an obstacle in your way. You tripped over the hard and heavy item, barely catching yourself with your arms.

"Fuck sake..." You cursed under your breath as you got to your knees and looked at the damned item. You realised it was just another book. Although unlike a regular book this one was huge and covered in a rather unique material - Some thick leather.

As you were standing up you took the heavy book. You carried it over to a nearby table and started examining it. It was written in a language you didn't know - It appeared to be some ancient language, but what would a book like this do in a common library.

Being unsure of what the book was about you decided to open it and find out hopefully. Immediately a stench hit your nose, the book reeked of dust and unpreserved paper. And it showed as the pages were torn partially and yellowed.

Despite those facts as you flipped through the pages, you realised the book was some sort of an ancient compendium on animals. That would generally explain why it was so thick, as you've checked out the pages you realised that the book probably stored information about most if not all animal species of the world.

Of course to your dismay the descriptions were still in the unknown language, but there were at least simple drawings depicting the animals. More curious were the symbols under the drawings, which almost seemed like glyphs of sorts.

You had a notebook with you and a pencil - You've never seen glyphs like those. For quicker access later you decided to draw a copy of one of them. You flipped through the pages looking for something more interesting than an earthworm or a rat. You finally found an animal that caught your attention.

On the page you looked at was what seemed like a species name, the animal drawing, an enigmatic glyph and probably a description of the animal. As you've planned you used the pen and notebook to sketch out the weird symbol. You planned to ask an antiquarian about its possible meaning.

You closed the compendium and wanted to pack it inside your bag, really curious about the book's secrets. You didn't go to the city library too often, but sometimes it was a necessity.

You closed the compendium and wanted to pack it inside your bag, really curious about the book's secrets. As you were about to pack your notebook, you noticed a very odd sight. The glyph you've drawn was glossy at first, but then started emitting a bright green light from its contours. You stared at it in disbelief, who would've thought that drawing a mythical glyph would actually cause some magical reaction - You chuckled at first, but the situation was actually increasingly more unsettling to you.

The light started to fade out, but you didn't wait for it to fully disappear. In one swift motion you closed your notebook and thrown it into your bag, sighing in relief that the aura seemed to completely disappear.

You didn't believe what you just witnessed, the book actually did contain some special knowledge. Your heart started beating faster - You thought it was because of the thrill. You realised you could get rich off this book. Maybe become some sort of a celebrity, showing its secrets to the world. Unbeknown to you, your body started to sweat. You instinctively wiped the sweat off your forehead as you thought about what to do about the revelations first.

"Unbelie-" You murmured, but stopped as you realised you voice sounded weird, deeper. This made you stop contemplating about the profit gains from the book and its magic as you coughed several times, trying to fix your voice.

"Got sick or... What...?" You muttered as you realised your entire body felt weird. You felt unnaturally heated up and sweated profoundly by now. You prayed your condition didn't change because of the book's magic.

Without thinking about it more, you reached out your hand to grab your bag and that's when you noticed it. The hair on your hand grew denser and changed colour to black. "W-What the fuck?!" You exclaimed as you felt the hair extend in length and spread across your entire arms. Feeling the similar itching on your chest, back and groin made you guess you were growing similar hair all over your body by now.

You started piecing the puzzles together and guessed that the symptoms might have been caused by the glyph's magic. "Noononono... Shit, wh-what to do...?!" You stammered trying to think rationally, but you constantly felt new feelings invade your body. You felt like your entire skeleton started aching, your muscles throbbing and flesh across your body swelling in a horrifically slow manner.

You started panting as you entire body felt hot and continued to sweat, your clothes getting completely soaked with your sweat. You felt your shirt and hoodie get tighter on your frame, something very wrong was happening to your body. You grimaced as your entire torso slowly broadened and strained your clothes.

"Ghn-Ghod... What's happening to- Mghhhhee!" You groaned in equine manner because of your discomfort and stumbled around in panic. You were thankful the library was very modern and automatic, which meant nobody around, especially at this late hour.

Your torso continued to balloon out into inhuman shape. Your rational thoughts to help your situation were interrupted constantly by new and bizarre discomforts. You felt like your insides churned inside you, growing bigger and reshaping - Making you feel queasy.

You felt your ribs pop as they grew into bigger and rounder shapes, barrelling out your chest painfully in your clothes confinement. Until you felt several ripping sounds and your shirt tore in half because of your increasing body mass. Your unzipped hoodie still stretched on you.

"Iaaah...! I shouldn't have... Dr-Drawn that glyph... It huuurghts...! M-My chgeeeest!" You grunted as your chest slowly neared its final, humongous size spreading your shoulder blades apart as they elongated painfully. Until your hoodie's sleeves ripped in places and finally it too slid off your bulging frame.

You barely kept your weight on your two legs, feeling like you'd fall over any moment now. That moment came when you felt your stomach swell out and start to painfully stretch your pants. Especially as your hips and pelvis started growing. You felt your legs' stance shift and you were forced to drop onto all fours.

Your turned your head back and stared as your inhuman silhouette was sprouting coarse black hair all over. Not hair... Fur - You realised with doom. You've drawn a horse symbol, your body started to slowly resemble one.

"Ghnhnooo... Shit, I chant bechome an animal...!" You mumbled in panic as you struggled to form human words when you felt your shift grow bigger and wider inside your mouth. Your incisors were making it hard to speak. You felt a weird gap form between your teeth as your dentition was becoming gradually more equine.

You didn't feel like you even deserved that kind of fate, you weren't a bad man. And yet the transformation from a human into a horse felt extremely painful and like some sort of a punishment. Maybe the glyph was meant to punish people in the ancient times. - You pondered as you gritted your horse teeth from the pain. You had no comprehension of what you'd be able to do now to reverse the metamorphosis, so you just tried to endure it without passing out by now.

You felt your ass harden with new muscles as it became inhumanly big. Your sweatpants had enough of it, they started ripping apart - Holes formed in them exposing your darkening and toughening flesh. You tensed up your rear muscles, that along with your ass gaining mass made your pants finally tear to a point they slid off your body ruined. You glanced back and noticed your boxers fallen off you as well - All of its three pieces.

Your upper legs started readjusting on your wider lower torso skeleton and you felt powerful flanks form, slowly spreading your butt cheeks apart and humiliating you further as your butthole tasted the chilly air, resting exposed on your altered rear. You felt it change texture and pucker out making you blush.

You felt your limbs start to reinforce themselves with additional muscles. In the same time you felt intense aches in your bones as they felt like they bent unnaturally to make you fit for a quadrupedal way of life. Your arms lengthened in places to fit your changing legs. You gulped as you felt your hands and feet start to stiffen.

In the meantime you felt the base of your neck bones tense up. Suddenly they snapped and your neck was forced higher up on your torso, readjusted for four legged stance. "Ghhhhhhhnheeeoww...!" You weren't able to keep calm as you felt your neck start to broaden with muscles and painfully form new vertebrae as it lengthened.

As your neck slowly finished lengthening you realised you were able to bend it more. You turned your head back and whinnied distressed as you realised your lower body was almost entirely that of a horse. You shook your head feeling ashamed of not even being able to speak anymore with your altered vocal chords. Your body was almost fully covered in black fur, glossy with your sweat. You felt longer fur grow and form a mane along your spine and neck, reaching your slowly changing head.

You felt a splitting headache as your skull started changing shape. You kept shaking your head as you felt your head slope down and you cranium deflate painfully - Squeezing your brain into a more compact shape. Your human hair blackened, grew longer and became a part of your luscious mane.

Your ears were becoming thinner and more sensitive as they were pulled into moveable, pointy equine ears. Pitch black fuzz grew out of them. You felt an intense pressure in your jaws and cheekbones as they started swelling larger and pushing out, stripping your head of your human contours.

You neighed madly as your jaws painfully surged forwards. The bones stretched your flesh painfully and slowly formed a horse muzzle. Your nose was pushed further away from the rest of your face by your growing muzzle. Your nostrils flared out and widened as your nose reformed into its equine counterpart.

Your broad extending muzzle pushed your eyes apart. You blinked them devastated and you felt your pupils getting stretched wider into more horizontal shapes. You eye colour became duller and your vision became wider as you opened your eyes.

As your head was slowly getting remolded into that of a horse, you felt your limbs slowly finish changing. Your digits except for the middle ones melted down. Your middle digits on each limb grew longer in contrast. They swollen out and started to resemble hooves as what was left of your nails formed round, protective shapes around them. You stomped your hooves, clopping wildly as your transformation intensified.

You felt your thickened spine start to elongate and put a pressure on your tailbone. You felt a new appendage push out above your muscular rump, forming a short tail. Your tail grew more vertebrae and slowly took on its final shape. It slapped your ass without control, you hated to admit it felt sort of good. Your newly grown tail sprouted long black horse hair.

You snorted hard with your muzzle as you felt it slowly grow out long enough for your head to be done changing. You felt your body thicken with muscles and grow some more to finally be the size of a mighty... Stallion.

Your equine eyes went wide as you felt a warmth surge to between your athletic hind legs. It centered at your manhood which was mostly unchanged until now. You stomped your powerful legs as you felt your balls swell with virile horse seed. They churned and became bigger, your ballsack skin became more leathery and covered in black fur which stimulated you more.

You walked around in a circle on your wobbly legs because the pleasure slowly started to overwhelm you. You felt your cock further alter and grow longer underneath of you. It lengthened to match your new form. It was painfully erect, but pulsed and broadened further into its tube-like shape.

You weren't able to control yourself with your lust-addled mind. You fallen onto all fours, thrusted your hips a few times feeling your cock enlarging beneath you and making you whinny in bliss. You rolled over onto your strong back and thrashed your legs in bliss as your cock further shifted.

What remained of your human foreskin receded. In its wake black flesh started forming at the base of your growing cock and slowly enveloping it, you realised with a pounding heart that you were growing a horse sheath. You watched your cock swell larger and longer as it bobbed and slapped your stomach making you snort in bliss. Its flesh changed colour to darker, your cock was becoming partially mottled and animalistic.

With a wild whinny of lust you bent over and craned down your neck. You managed to catch your cock with your muzzle and started licking it with your thick equine tongue. As you lapped at it, leaking precum you felt your cock head change shape. It widened and grew taking on a mushroom shape almost. You caressed it with your plump lips and you felt your genitals finish changing.

You felt your massive cock start to throb, your onyx balls clenched and your heart skipped a beat. You threw your head back as you felt your massive stallion orgasm washing over you. Your balls clenched multiple times forcing out several huge streaks of cum that hit your muscular ribcage, neck and head staining them with lust.

You humped the air for a while as you felt the ecstatic spasms. Your huge shaft spurted out last loads of cum and you laid on your back with your appendages splayed out. You felt amazing - Careless and free as your orgasm got to your head.

The lust lingered in you for a while, but soon you felt like you calmed down enough to get up at least. Your consciousness came back to you and you realised what situation you've gotten yourself into. You rolled onto your four legs and slowly stood up. You just transformed into some purebreed black stallion by the looks of it.

You wanted to turn around and look for the bag with the mystic book, but as you moved you started comprehending how ungainly you were between the rows of shelves. Your hard ass hit a shelf, you watched it start to collapse and kicked your hind legs in panic. You dashed forwards and the shelves behind you tumbled down like domino.

You realised what you've done, turned back and understood that your bag was probably under all those knocked over shelves. You didn't have hands anymore, you had no chance to dig out the magical book. You whinnied silently as you realised you had no way to turn back from this nightmare. Not to mention the ruckus you've caused - You really hoped nobody heard you.

Your ears perked up and you quickly turned towards the sound. Two meters away from you stood a young woman, you recognised her - She was the librarian's assistant, but why was she- You stomped your forelegs in fury as in her arms you noticed your bag with the book sticking out of it. She must've known! Did she leave the book on the floor on purpose for somebody to find it?! You shook your head to get the mane out of your sight and started marching towards her.

"I-I didn't k-know you'd find it. I didn't e-even think it would ch-change you..." She started trembling and stepping back as your intimidating silhouette was coming closer to her. How dared she?! She knew it was going to possibly transform an innocent human into an animal, and yet she tried her luck?!

You snorted angrily and reared up, standing on your hindlegs you wanted to teach the insolent woman a lesson. "I knew you'd be mad. NOW!!!" She shouted in the direction of the entrance disorienting you. You suddenly felt a sharp sting in your hip. Whatever stung you, started working immediately and you limply tumbled down.

You turned your head back and noticed a tranquilizer dart sticking out of your side. That bratty bitch... - You thought as your head went limp and hit the floor. In your last moments of being conscious you watched as some veterinarian looking man came over to you and patted your head.

You felt like you slept for hours if not days, maybe those assumptions were all wrong. Nonetheless you finally slowly came to your senses. You wanted to stand up as you usually would. Just to clumsily fail and crash your massive body over the cold ground. You realised with sorrow that you were still a horse.

You blinked getting used to the bright light and slowly stood up onto all fours. You noticed some weird door in front of you and a sort of window above them. You realised you woke up in a horse stall in the stables.

Suddenly you heard a woman's voice. "You're finally awake! How do you like your new home, shy guy?" Farmer girl questioned you as you walked back away from her, shocked of your new location. You felt like in some kind of a nightmare. It seemed like you'd have to spend the rest of your years alive as a horse living on a farm...
