Night shift

By The Shadow Demon

(Woman into Horse)

Amber let out a sigh, pressing the button to her car to lock it. With a simple turn Amber began to walk from the near empty car lot to the Equigreen Laboratories, the light post glowing softly against the dimming sky. Pulling out her ID card, Amber walking to the side of the two large glass doors. Placing her card on a scanner. With a moment she heard a click allowing entrance and the start of her shift. Walking past the reception desk, no one behind it. Only a computer and a phone on it. Walking past it, past the series of elevators, the stair case, to the lone door with the capitol bold letters of “SECURITY” written on it. Pressing her id on the scanner next to the door, hearing a low buzz, Amber open the door to the small room full of screens, a single table with a single man sitting at the large table.

“Afternoon,” Mark stated not even turning to Amber as she walks by and straight on one of the steel locker.

“Anything to report?” Amber ask opening the locker grabbing a walkie talkie, a torch and her holster.

“Same shit, different day!” Mark stated ending it with a yawn and a stretch of the arms.

“Alright, I’m going on patrol! Watch my six!” Amber stated clipping all her equipment to her belt as she leaves the security room.

“Sure!” Mark lets out another yawn, this one long and loud. A clear sign that once again, he won’t. The twenty-six year old never thought she would have a career in security, the way she looked. The long black hair, green eyes, double D cup breasts, slender frame. She could easily be a model, instead Amber wanted to be a cop. However this was not meant to be, being cut from police department during her rookie year. So here she was, a security guard for some billion dollar corporation. Continue on her routine, checking doors, looking through windows, seeing if anyone was still working. Amber sighs, knowing the routine, her path of her patrol. While it focus on the main areas, it didn’t go everywhere. Grabbing her walkie and bring it to her cheery lips she clicked it.

“Route one clear, moving to route two!” She stated getting no response, a typical thing she got on her patrols. “Yeah, no doubt he fell asleep again!” continuing on, Amber wonder what was the point of this job if she was the only one that took it seriously?

“Just have to wait another four months to retry for the police again!” Amber mumble, moving her flashlight to one section to the next, all again and again. Uneventful. Continuing on on her route, as she hits the end of T section, her usually route took her in the right section but never to the left. Turning down the left corridor, seeing the two security doors only few feet away from her. Through her time here, she never seen behind those doors. Always told to stay on her route. Amber just stared, her flashlight pointed at the doors slowing moving to the card scanner that sat beside it.

“I wonder,” Amber pondered, walking up to it. Grabbing her ID card, Amber just stared at the scanner for a moment before placing it on it.

CLICK

The two doors slowly swung open, giving her access to the secrets behind it. With an eyebrow raise, Amber slowly walk in the corridor as the doors swung shut behind her.

“Guess we will see what’s behind door number one,” Amber said to herself, her flashlight focus on the hallway in front of her. Walking down the hallway, seeing series of windows as she scan her flashlights over every room, seeing series of high tech machines in the rooms. Far more advance then she had seen in the rest of building she had seen.

“Wow, what do they do here?” Amber pondered, continue on soon coming across a rather large open room. Entering into it, Ember eyes scan with her light of her flashlight, the floor and roof seeming some kind of machine, focus mainly on a single small enclosure paddock with metal fencing around it. Amber curiosity grew, she knew that Equigreen dealt with horses and keeping them healthy with medicine, enhancements, but what had to do with what ever she was looking at. Walking into the room, trying to get a better idea on what this was build for exactly.

“Maybe some kind of scanner for horses?” Amber ask no one leaning against the metal fence the sat between her and the machine. “A test set-up perhaps!”

Leaning down to slide through the steel frame of the fence, her flashlight scanning around the floor seeing small circular closed holes through the entity of the flood.

“Defiantly some kind of test area!” Amber remarked. The sound of machinery waking catching her completely off guard, pulling her gun out aiming into the open air.

“New-New-New New subject detected!” A robotic voice echo from the speakers as Amber looks around hear metal turning and activating as the who room lit up, all the lights focus on her.

“Okay time to go!” Amber whisper as the second she took her foot off to run it slammed back down the feeling of hard metal against her leg. Looking down to see a restraining cuff had attach itself around her ankle.

“What the hell?” Amber cries out as another restraint cuff wrap around her other ankle, locking her in place.

“Hey, Hello?” Amber calls to see anyone was out there. Nothing. Quickly she for her walkie, and bringing it to her face.

“Mark! Mark come in! Do you hear me Mark?” Amber call into the walkie, letting out a scream as a restraining cuff launch up and clasp around her wrist and pulled it down so fast, it causing her fling the walkie out of the metal paddock, far from her reach.

“No no no no!” Amber pulled against the three restraints locking her in an awkward all fours stance with her ass up in the air. Amber turns to her only hand free get locked down leaving all four of her limbs in her standing all fours stance.

“Hey let me go!” Amber cries out as beam of light shot down, scanning her for a moment for vanishing.

“Subject: Female. Numerous errors detected. Barriers nodded. Beginning phase one!”

“Phase one the hell is phase- umpphhhh!” Amber questioning getting cut shot as a metal gag with a tube running down to base of the floor slammed in to her mouth as she feels a plastic tube be push into her open mouth.

“Mmmmph…. Mmmmmph!” Amber muffled screams went no where, pulling against the gag, but with her body locked into place, this resistance was pretty much mute.

“Beginning Phase One!”

Amber could only watch as series of mechanical tendrils burst from the ground surrounding, but with the gag she couldn’t express her objects as they tear away at her clothing.

‘No no stop!' Amber thought still her muffled screaming coming from the metal gag. With limit movement, Amber all but just stand as her security uniform was torn way. Her belt that held her gun slid off with ease leaving her in her underwear, her black bra and panties fully exposed to the open air.

"Mmmph... Mmmmmmph!" Amber muffled as the robotic arms then remove her bra and panties. Leaving her completely naked.

"Phase One Complete! Beginning Correctional Re-figuration!"

Amber could do nothing but stand on all fours feeling a surge pulse through her entire body, like every muscle, every cell was being energised. As every inch, every part of her, even her soul was pump by something else. Something more. Something wrong.

"Mmmmph!" Amber whimper as it started at her tail bone. Pushing out further and further, developing longer. hearing each crack and pop every new bone, every tingle of new muscles developing. Turning her head to see a tail forming from her backside as black hairs start sprout, long and lushest just like your hair. Pure black haired horse tail forms behind her. feeling a flicker in her mind, of new neurons, new muscles forming into her mind as with a sudden muffled gasp she felt it move. She had made it move.

'No way, this- this can't be happening to me, is this machine changing me into a... a-" Amber's mind race watching her tail grow to a full length. suited to be on the end of a horse than a human. Her thoughts cut off as another surge hit her, this one focused on her legs.

The bones in her feet started to stretch and fuse. Her toes elongated and merged, the nails darkening and thickening into a single, hard surface. The arch of her foot rose, transforming into a solid, elongated structure. The skin tingled and crawled as coarse, brown hairs began to sprout, spreading up her calves. She could feel the muscles swelling and reshaping, her knees bending in a way that felt both alien and yet strangely natural. Her heels lifted off the ground as her legs lengthened and restructured, her thighs thickening with new muscle.

"Mmmmph!" Amber whimpered, the sound vibrating through the gag. She tried to fight it, to will her legs to stay human, but the transformation was relentless. Her ankles shifted, her foot twisting back until she was standing on the tips of what were once her toes, now forming a single, solid black hooves. The brown fur spread rapidly, covering her entire lower legs in a sleek coat.

'Not my legs, please stop! Somebody please help me!' Amber mentally pleaded helpless to do anything but watch watching her hips now start to shift, growing wider and wider as her ass develop along with giving her one hell of a back end to make any woman jealous. yet they still grew pass any human limit and into animal. Equine.

'Please stop! Please stop! Please stop!' Amber repeated over and over as her spine started to crack and pop. Each new vertebrae formed adding length to her growing body as her rib cage started to expand. Her torso lengthening as her insides start to rearrange. She could feel her stomach twist and churn, her organs shifting to accommodate her new, larger frame as vagina shift moving behind her, darkening, growing, shifting, giving her the full behind of a full grown mare. Feeling a strange pressure in her chest, a deep, resonant hum that seemed to vibrate through her entire being. Amber face somehow got more red for the feeling was overwhelming, a mix of pain, pleasure, and a terrifying sense of rightness.

"Mmmmmph..." A new moan escaped from behind the gag, a deeper, more guttural sound than before. Her double D cup breasts start to move south, gaining a darker tone, moving underneath her now two equine hind legs.

'Not my breasts, they're becoming... they're horse teats!' Amber just only watch her double D breasts now sat handing from her hindquarters ready for any foal. With tears running down her face, as her chest barrels outwards while her shoulder blades widen and an adjust popping and crack. Then a series of popping cause sudden muffled squeak from her as everything no long felt off, but normal. like her body was no longer being forced into a position is wasn't built for but for something on four legs. Quadrupedal.

'Oh god, oh god, i am standing like a horse now!' Amber let out a muffled whimper feeling the pricking of her brown coat of fur moving over her body, over her stomach, chest, back, shoulders and move down her elongated arms as a familiar growing numbs hits her hands and fingers. Amber sob staring in horror as her fingers merge together, the nails darkening and thickening. her palm stretch. A pop as she screams in the gag as her wrists twist, her arms reshaping to become forelegs as her hands become hooves. Just like her feet had become.

'No! My hands! Not my beautiful hands!' Amber stared at them, transfixed, as her elegant fingers, the ones that had once held a pen, a gun, a lover's hand, fused into solid, useless black hooves. Her arms now matched her legs in length and structure, completing her quadrupedal form. The brown fur swept up to cover them completely.

'Mmmmmph... mmmmmmph" Amber tried to state looking over her body to see from the neck down she was fully a mare. a mature brown coated, long black tail, beautiful mare

"Phase two complete! Beginning Phase Three: Olfactory, Auditory and Vocalisation enhancement!"

'No! No more please! Just leave me be!' Her mind races, as she tries to move her head only for it to be held still as the restraints now hold her neck in place. A feeling of stretching and pulling on her ears as they travel up her head, elongating, becoming pointed and covered in the same brown fur. The sounds of the room suddenly sharpened, became clearer, more distinct. She could hear the faint hum of the lights, the whirl of the machinery, even her own frantic heartbeat as if it were a drum. And then they moved, she felt them move. Capturing everything around her.

'Everything is so loud!' Amber thoughts where cut short as her nose and upper lip started to push out and merge, her nostrils flaring wide as her jaw realigning with a series of painful pops and cracks. The changes were agonising, a symphony of reshaping bone and stretching cartilage. She could feel her teeth shifting, growing, flattening into the molars of a herbivore. Her tongue felt thick and clumsy in her mouth, pressed against the new, elongated shape.

'My face! Please not my face!' The gag, still lodged in her mouth, was now a tight, constricting presence in her newly forming equine jaw. She tried to scream, to beg, but all that came out was a choked, gurgling sound. Her face continued to push out, the skin stretching and tingling as it transformed. Her once beautiful, human features were vanishing, replaced by the long, expressive muzzle of a horse. With a series of pops her neck joined growing longer and thicker. Her long black hair tied in a ponytail a single mechanical hand removes the hair tie, causing her fall down as it form down her elongating neck. Becoming her new mane.

'My eyes... what's happening to my eyes?' Amber eyes were next to change, feeling a strange pulling sensation as her eyes moved further apart and slightly larger. The world took on a different quality, a wider panoramic view, with a blind spot directly in front of her nose. She could see the entirety of the paddock around her and the majority of her body without having to turn her head.

Finally the same brown fur sprouted across her face and down her now long neck, with a singe strip of white down her muzzle. The transformation was complete.

'Phase Three Complete! All barriers removed!' the robotic voice echoed. The gag retracted from her mouth with a slick, wet sound, the cuffs released her hooves with a soft clang.

Amber stumbled forward, catching herself on her new four legs, each one shaking by fear and the experience of the experience of the transformation. Amber now free from the gag first instinct was to scream, to run, to do something. She took a deep breath to let out a human cry of terror, to cry out for help but what came out was a high-pitched, panicked whinny.

'Oh god my voice, my voice it took my voice too?!'

Amber snorted her large head turning to look over herself. Nothing. Nothing remained from her human existence. Taking an experimental step, hearing her hoof clop against the steel, one hoof after another, each careful step after another.

'This so weird, i am walking on all fours and it feels so natural as well' Amber thought walking around in the paddock with no issue of any kind.

"Subject showing signs of movement! Transferring subject into paddock!" The robotic voice states as a part of the steel fence retracted into the floor, allow her to walk out into a fence corridor lead out to the paddock outside.

Amber hesitates for a moment, her large equine ears twitching at the sound of the machinery, her new, powerful senses picking up the faint electrical hum of the room. Taking another step out, she moves into the larger space. The floor beneath her hooves changing to solid harsh of metal to the solid ground of earth and grass. the cool night air nipping at her flank. Hearing a clank of metal, the gate to the paddock now closed leaving Amber now standing in a paddock, as mare, at night with no one knowing what happened to her.

'Okay, okay Amber just think this through, soon or later Mark will notice i haven't return and start looking for you, and with all these cameras it won't take long until he will figure out that you are not a horse but Amber!' Amber told herself, her tail flicking behind her in annoyance as she knew all to well it be morning until Mark might. MIGHT. Notice. If he didn't than the morning shift would. All she had to do was wait.

'I might as well take this body a test ride while i have it before i turn back, no harm in it right?' Amber thought walking deeper into the paddock unbeknown to her a screen on a machine that read: PROGRESS COMPLETE.

Underneath reading.

ESTRUS LEVEL AT REPRODUCTIVE STATUS. IMPREGNATION POSSIBILTY: 100%

Amber continuing to move deeper into the paddock, her pace from a soft walk to near gallop feeling every muscle in her body, the difference that her body could do. It was impressive, remarkable and scary all at the same time. Finally coming to a stop, feeling her larger heart and lungs doing what they are built for.

'Wow, just wow, this is so... wow!' Amber thought on just how much energy this body had and how much you still had left. Standing feeling the energy in her, Amber's ears flicker to a whinny as her head followed to the sound of a black horse trotting his way towards her.

'Oh hello there,' Amber thought trying to say hello which on came out a whinny. as the black stallion slows to a walk, his nostril flaring no doubt smelling her her, as she did the same. His scent strong and musky. a scent that seem to sent warm shiver down your spine to your vulva feeling it moisten.

'The hell? Did i just get turned on by just smelling him?!' Amber thought letting out a snort of defiance, she had control over her body not the other way around. Yet with each breath she took in was another another shot of warmth that cause her vagina to moisten and wink. It's primal lewd need growing with each passing moment.

'get a hold of yourself Amber! you a human, a human not a horse! Not some mare to be mated and produce fouls!' Amber thought taking a step away from the approaching stallion.

The black stallion let out a soft nicker, a deep, resonant sound that seemed to vibrate through the air and straight into Amber's new body. He took another step closer, his dark eyes intelligent and curious. His musky scent washed over her again, stronger this time, and a fresh wave of heat pooled in her loins.

'No, no, no... get away from me!' Amber screamed in her mind, but her body betrayed her. Finding herself taking a step back, not in defiance, but in a gesture that was instinctively inviting. Her tail involuntary lifted slightly, exposing herself to him. A soft, whinny escaped her lips. She could feel her vulva winking again, a rapid, rhythmic pulsing that sent jolts of pleasure through her. Her human mind recoiled in horror, but the mare's body was singing a different song, a song of readiness and need.

The stallion seemed to understand her unspoken invitation. He moved closer, his powerful muscles rippling under a gleaming black coat. He lowered his head, his warm breath ghosting over her flank, and then he nipped her gently, just above her hock.

'No Amber control yourself, you can't let this happen! You are a human not a mare! A human!' Amber mentally shouted as she feels his hot breath against her needy vulva her body fluids already slicked it for easy entry. Amber whinny the sound of stress and arousal even her vocals sounding she wanted him.

'No I don't a stallion fuck me, I don't want a stallion in me! I don't want a stallion even near me!' Amber thought as her body took over, her tail lifting fully out of the way, presenting herself fully to him. Her new body knowing exactly what to do, her legs adjusting position to brace for the increase weight.

The stallion didn't hesitate. He mounted her with surprising speed and gentleness, his powerful forelegs gripping her sides, the weight of his body settling over her. Amber felt a surge of panic mixed with a terrifying, undeniable thrill. This was real. This was happening.

'This isn't happening! This can't be happening!' Her mind was a frantic mess, a torrent of denial and fear. But her body... her body was a traitor. A deep, guttural moan escaped her lips as the stallion began to probing around, her mind frantically as she felt him circling closer and closer unti-

The stallion found his mark. He entered her with a single, powerful thrust, and a wave of intense pleasure, so sharp it was almost painful, shot through her. He was huge, filling her completely, stretching her in a way that felt both alien and exquisitely right.

'NO!!! Get out of me! Get out of me you beast!' She screamed internally, but the sounds that came from her throat were anything but protests. They were whinnies of pure, unadulterated ecstasy. The stallion began to move, his hips thrusting in a steady, primal rhythm that echoed the ancient dance of their kind. Amber breathing began to grow loudly, heavier, layered. with each thrust into her, he went deeper into her, each thrust was another wave or pleasure her body had no control over feeling.

'No... no please...' Amber mentally pleads as she lowers her head, finding herself pushing back into him. Wanting ever inch of his massive penis in her. Wanting him deeper. Wanting to be filled with everything he has to offer. Amber's resistance was fading into the background, those twitches of trying to buck him. to stop him fading with each thrust leaving on the pleasure of the action she was taking part of. Thrust after thrust Amber felt it build with each pleasurable intake, every moment building to something she knew that came with any sexual intercourse.

'No... no.... please... stop...' Amber mind plead, to the stallion, to herself, to maybe even to the pleasure it self. Thrust after thrust she took him. Each one more then the last, Her breathing now heavy as the stallion continues his thrust rhythm. The heat of his body, the smell of his sweat, the feeling of his strong legs holding her in place.

'No... stop... please... no... stop...' Amber's mind slowly breaking with each wave of pleasure. A distant memory surfaces. A memory of a boyfriend. A memory of a memory of her on a bed. On a different kind of fours.

'No... this is wrong... wrong... wrong' She thought, her mind trying to pull away from the pleasure. To hold on to her humanity.

'Wrong...' her thought fading as another memory surfaces. A memory of a different boyfriend. A memory of being taken from behind. The pleasure was... nice. But nothing compared to this.

'No... no...' Another memory surfaces of another lover. Another encounter. Each one a fleeting ghost, quickly consumed by the overwhelming reality of the present. Each past pleasure a pale imitation of this raw, primal act. She was being claimed, possessed in a way she had never experienced.

'No... stop... no...' The thoughts were losing their meaning, the words dissolving into the raw sensation. Her mind was a ship in a storm, her human consciousness the last flickering lantern on the mast. The stallion's thrusts grew more urgent, more forceful.

'Please... please...' the stallion continue to thrust. slower. harder. She could feel it throbbing in her. feeling her own limits reach it peak.

'P...Please...'

Another thrust as the two horses whinny loudly reaching their climaxes as the stallion fill her equine womb with his hot wet seamen. Amber's mind went blank nothing but the sheer pleasure of the climax overflowing every sense that is human. only the primal satisfaction of animals primal need remand. Having completed his task, the stallion dismount, letting his penis to slide out of her with a sickening sound as he walks away and starts grazing. Leaving Amber standing their, her mind blank and body shaking.

"Is that all the recording?" Lucas the head and CEO of Equigreen Laboratories ask looking up to the head of security,

"There's... additional times of her... being mated before we discovered the recording and the machine's records"

Lucas nods as he turns back to the security recording of the whole event, the transformation, the mating sessions, all of them.

"And how many people know about this?"

"Including us, just five sir!"

"Make sure they don't talk about this, this is something beyond we are capable of... and how is Miss Casterdin?"

"Panic, scared, as fast as we can tell she still her- just now a horse, sir!"

Lucas saving the footage to a private server before deleting it. "Good that is good! That means she can be reason with, communicate with! We can't let this get out... the news would kill us."

"And what about Amber sir?"

Lucas stand up from his desk as he looks out massive office window.

"We monitor her, get out best scientist on this, I want to know exactly how this happened, no doubt she would want to change back, just maybe after a foal or five!"
