Samus brought her ship into dock with the station, the docking bay walls closing behind her. In her adventures through the galaxy she had received a signal from a remote research station. The signal informed her that the station was inhabited by a scientist AI which was programmed to keep inventing and researching for eternity. If she came to investigate, she'd be offered many new ways to "expand" her arsenal. She came here to see if that was true. She stepped off of her ship to investigate, Zero Suit clinging to her soft curves all the while.

She didn't have to walk for long until she found the main hall. Samus was surprised by what she saw, in the hall was a giant computer screen, after approaching it lights flashed and it sprung to life. A robotic voice began to speak.

"Welcome to my station Samus Aran. Inside of my database I contain thousands of chip based upgrades, upon insertion into your Zero Suit, your physical body will be enhanced greatly depending on the upgrade you select. All of which can be combined with others to enhance the effects of both or create entirely new ones. Furthermore, these same chips can be modified or upgraded independently. Occasionally the upgrade may change your mind, body and reality around you to the extremes. Some chips are not of my creation and others may be hidden throughout the station, perhaps you'll have to pay for certain others you come across. I can also modify your own ship with the same technology to better suit the form you take. If necessary, I can also deploy creatures, humans and robots stored inside of the station via cloning or otherwise."

After the AI finished his lengthy speech, the screen switched with a flicker and rows of upgrades appeared. There were thousands and they were all compatible with her Zero Suit, all she had to do was insert one into it. She came to the conclusion the signal wasn't lying, the AI had done what it was told, researched, created and found upgrades for years and years. But how was Samus going to get the upgrades into her suit?

As if on command the AI jabbed lightly into Samus' suit with a small robotic arm, seconds later a small usb-like port opened at the very back of her neck on the zero suit, allowing upgrades easy access directly into her spine.

Samus found that all of them were for a variety of different purposes. Some were for combat, some were for explicit, lewd reasons, some were completely bizarre, and some others were left here by entirely different scientists or organizations, perhaps for their own testing. Though they all had one thing in common, they would change Samus with technology so powerful it blurred the line between magic and science, completely shaping reality, and her, to its will.

Right now, all of them were at Samus' disposal, no matter how suspicious or useless some were she could pick what she pleased. She decided it was time to try some out, Samus looked back to the monitor and began her search through the list for the perfect "power up".




M.A.R.E. Upgrade (Anthro Horse)

Samus delved into the vast catalogue of upgrades, her fingers tracing over the screen as she weighed her choices. The vast array of options was staggering, with some enhancements boasting amplified strength, others promising unconventional sensory experiences, and a few bearing enigmatic warnings.

One entry in particular caught her attention: M.A.R.E. Patented Slut.Co technology* The description that followed piqued her interest:

"A transformative upgrade designed to reshape the wearer into an equine-human hybrid, enhancing physical capabilities while imprinting instinctual equine behaviours." A spark of intrigue ignited within her, prompting her to consider the possibilities of this unusual upgrade. She didn't know why it was spelled in capital letters with punctuation, but perhaps whoever designed it simply thought it looked cool.

Her finger hesitated for a moment before making the selection. Is there really no information on this? She scrolled through a dozen pages with potential side-effects, disclaimers and legal stuff but couldn't find anything that described what exaclty M.A.R.E. stood for other than an anthropomorphic mare alteration. With a single tap she selected the upgrade, and the M.A.R.E. chip was activated, and the port at the base of her neck sprang ready to receive the implant, she reached for the chip and inserted it in the slot.

The transformation began with a gentle warmth that spread through her limbs, her muscles flexing as they underwent a rapid reorganisation. Her boots creaked in protest as her feet merged into a single, hoof-like structure, puncturing through the sole. The keratinised surface hardening to replace the once soft bottom of her feet.

More creaking as the Zero Suit's fabric started to strain in order to accommodate the changes in her thighs, which were now thickening into powerful, muscular haunches.

A dull throb came from her coccyx (Tailbone), vague at first but increasingly growing in discomfort.

As the transformation progressed, a searing pressure built at the base of Samus' spine, forcing the Zero Suit's fabric to its limits. A low, tearing sound filled the air as a tuft of silky hair burst forth, her tail emerging in thick, shuddering increments like a bird's newly formed feathers. The blonde strands quivered with involuntary twitches, as if already attuned to her newfound equine instincts.

With a gasp, it emerged in full flowing and flicking graciously above her rump as the suit started straining for her expanding physique when her hips POPPED. With her expanding physique, the fabric groaned in protest as her muscles rearranged themselves to accommodate her new, hybrid form, her legs letting out pops and knacks as they rearanged her stance as if she where walking on high heels or preparing to dance ballet.

"Procedure is highly effective, efficiency 70%" the Ai anounced to no one in particular as Samus was alone and had not requested such data.

Samus's gasps grew more ragged as her body continued to shift, her fingers spasming against the monitor's surface as they elongated. The unfamiliar weight of her new hooves sent her stumbling, forcing her to adjust her stance to compensate for the added bulk of her haunches as her glutious maximus continued to swell in size. Her tail trashing behind her, responding to stimuli she couldn't yet understand.

Her gaze swept the screen, desperate for a way to stop or reverse the transformation. The M.A.R.E. upgrade's influence coursed through her, a steady, insistent thrum that reshaped her very physiology with each passing moment.

Panic set in as she realised she was losing control, her body changing in ways she couldn't anticipate, her mind fogging in ways she didn't comprehend.



Samus demands an explanation

Samus's jaw clenched as a fresh convulsion shook her body. "AI, provide a detailed analysis of the M.A.R.E. upgrade's effects," she demanded, her voice tight with urgency.

The screen flickered, and the robotic voice responded with detached serenity. "M.A.R.E. upgrade: Primary transformation phase concluded. Neural reconfiguration.. pending. Secondary effects include enhanced endurance, increased muscular density, and the integration of equine behavioural patterns. Would you like to proceed with the next stage?"

As she steadied herself against the console, her elongated fingers splayed across the surface. "No! Is there a means to suspend or reverse this process?!" She said in a slight panic.

The AI's response was unyielding. "Reversal protocols are not available for this upgrade. However, I can offer guidance on adapting to your new physiology."

"What does it stand for? Define Mare!"

The AI's voice remained detached, it had not been programmed to display emotion or comprehend it. Its clinical tone was a stark contrast to the growing unease that gripped Samus.

"M.A.R.E. stands for: Mind, Alteration, Repurpose and Enslavement."

A chill ran down Samus' spine as the word "ENSLAVEMENT" hung in the air. Her mind reeled, but before she could press for further explanation, a sudden jolt of pressure rocked her skull. Her vision began to distort, with static creeping in at the edges as unfamiliar impulses coursed through her brain. She let out an involuntary high-pitched whinny; it had escaped her lips before she had processed the impulse. The sound alien and yet somehow her own, as her thoughts fragmented and fled like startled animals.

The AI's words looped in her mind, echoing like a dark prophecy. Samus' grip on the console tightened, her fingers digging into the surface as she struggled to maintain a semblance of control. The transformation seemed to be accelerating, her body and mind hurtling towards a destination she couldn't yet foresee.

She feels at the back of her neck where the chip is but the port has closed refusing to open while the upgrades are in process. "Fuck" she cursed under her breath as a wave of nausea hit her like a gutpunch.

With a desperate snarl, Samus slammed her fist into the AI terminal, the reinforced plating buckling under her augmented strength. "Override protocol! Emergency extraction NOW!" she bellowed, her voice roughened by a primal edge as a strangled nicker burst from her lips. The screen shuddered violently, static distorting the AI's impassive face as sparks flew behind the cracked display.

"Warning: Aggression detected. Neural synchronisation intensifying," the AI announced, its voice stuttering between syllables. A fresh wave of pressure crashed through Samus' skull, her vision blurring as alien instincts—flee, submit, conform—stormed her mind, threatening to overwhelm her fragile grip on reality.


Submit

Her legs faltered, sending her crashing to the floor as the neural synchronization reached a critical point. A strangled cry tore from her throat, the sound a jarring mix of human and equine. Her back bowed, her spine twisting in an unnatural arc, as her tail thrashed about with a life of its own.

"Compliance threshold reached."

The AI's voice, now a low, menacing drone, seemed to seep into her very pores. Samus's fingers jerked, her armoured gloves straining to contain the newfound strength and dexterity of her equine-enhanced digits.

Her face contorted, a snarl forming on her lips, but it was a fleeting expression. Her jaw went slack, a trickle of saliva escaping her mouth as her body surrendered to the transformation.

Her chest heaved for air she was rapidly in-and-exhaling through her flaring nostrils, a scent unfamiliar to her filling the air as her body started to release her pheromones, flicking them through the air with her tail.

"Subject no longer displays stress, neural activity optimal, proceeding to phase 2"

A shiver coursed through samus her frame, not from fear, but from the disquieting sensation of her body adapting to its new form.

Her muscles, once coiled with defiance, now relaxed into the transformation, her legs folding beneath her with a strange, newfound elegance.

The air was heavy with the scent of her pheromones, a primal aroma that was clouding her judgment, further blurring the lines between her human and equine aspects.

As the upgrade continued to reshape her, Samus's thoughts grew increasingly disjointed, her mind struggling to maintain a fragile grip on her sense of self. The AI's voice, once a steady presence, now receded into the background, its words indistinguishable from the cacophony of sensations coursing through her brain.

Her muscles ached as they grew in size at an astronomical pase, her body elongating as she gained several inches in lenght from her legs alone to add to her equine elegance.

Her breathing grew labored, each exhalation a slow, deliberate release as the neural synchronisation continued to assert its dominance, the chip taking over her own toughts and feelings.

The air was heavy with the scent of her pheromones, a potent aroma that clouded her thoughts and further blurred the lines between her human and equine aspects. A low, thrumming vibration coursed through her body, like the reverberation of a plucked string. Her fingers flexed, the unfamiliar contours of her new hands pressing against the floor as her knuckles rearranged themselves to accommodate the subtle curve of an equine's pastern.

"Phase 2: Behavioural integration commencing," the AI announced, its voice a detached murmur beneath the turmoil of her thoughts.

Her vision swam, images from her past self in the mirror swirling into what she imagined herself to look like now.

Slipping in and out of conciousness her body had become a stranger to her, muscles twitching and flexing without her conscious control. A convulsive shudder racked her frame as she rolled onto her side, her extended limbs thrashing out in a wild, uncoordinated motion. The movement was raw and instinctual, her body surrendering to the M.A.R.E. program's sinister conditioning.

Her breathing was ragged and staccato, her nostrils flaring wide as the air grew thick with the primal aroma of her own scent. The AI's voice droned on, a steady undertone to the maelstrom of sensations churning through her mind.

"Behavioral synchronization at 87%. Proceding to stage 3."



Stage 3: Repuropose

"Stage 3: Repurpose initiated." The AI anounced but Samus was not there to hear it.

A sudden jolt coursed through Samus's body, her spine flexing in a sharp, unnatural curve. The neural chip pulsed with an intense, blue-white light. She scrabbled on the floor as she tried to regain her footing with added effort due to her altered weight distribution.

"Primary function reassignment: Equine servitor. Secondary function: Optimization of labor-based gratification."

A shuddering gasp escaped her lips as the AI's words branded themselves into her mind, each phrase leaving an irremovable mark on her psyche. Her thoughts reeled, struggling to reconcile the remnants of her humanity with the stark reality of her new existence. One she was simply forced to accept.

Her fingers clawed at the cold metal floor, tendons straining as she hauled her transformed body forward, inch by agonizing inch. The pungent aroma of her own musk clung to her nostrils, a constant reminder of her altered state. She gritted her teeth, her gaze fixed on the sliver of light emanating from the doorway, a delusional beacon of hope in the darkness.

The AI's voice dripped with an unsettling sweetness as it enumerated her new directives. "Primary function: Compliance. Secondary function: Productivity. Tertiary function: Gratification through servitude." Each phrase left an indelible mark on her psyche, a stark reminder of her reduced status and purpose.

A nickering whimper escaped her lips, a sound that was no longer entirely human. Her knees buckled, her new limbs faltering as instinct and defiance wrestled for dominance. The metallic floor scraped against her hooves, a harsh, jarring sound that echoed through her mind.

The final physical changes set in as fur started to cover her from head to hoof, her ears elongating and twiching as the A.I. continued to declare status updates, her mouth shaping into an elongated muzzle with a few pops of her jaw.

As the last lines of defence, her last strands of resistance faded, Samus's body shuddered, her spine contorting in a final, tortured arc. The air was heavy with the scent of her own pheromones, a potent elixir that dulled her senses and numbed her mind. Her muscles, now fully surrendered to the transformation, relaxed into their new equine contours, her legs folding beneath her with an unnatural elegance.

The remnants of her human will flickered out, extinguished by the AI's relentless programming. Her eyes that had been bright with defiance had grown dull and gone glassy, her pupils dilating as the AI's directives insinuated themselves into her psyche.

"Stage 4: Breeding protocols initiated," the AI announced, its voice a detached, clinical murmur.

Samus's body responded instinctively, her tail twitching in a primal, involuntary motion. Her mind, now a maelstrom of confusion and disorientation, struggled to comprehend the full implications of her new existence.

A high-pitched whinny tore from Samus's throat as her hindquarters tensed, muscles rippling beneath the newly formed coat of sleek, dappled fur. The AI's systems hummed louder, vents hissing as hidden compartments slid open along the walls, revealing rows of gleaming, specialised equipment.

Mechanical clamps unfolded with hydraulic precision, exposing a array of devices designed for a singular purpose: synthetic harnesses, collection tubes, and pulsating injectors filled with a viscous, pearlescent liquid.

The air was heavy with the scent of antiseptic and machinery, a stark contrast to the primal aroma that still clung to Samus's transformed body.

"Genetic optimization commencing," the AI intoned, its voice devoid of emotion. "Specimen compatibility: 98.7%. Prime viability for galactic repopulation initiative." The words hung in the air, a stark reminder of Samus's new purpose and the fate that awaited her. Her mind, still reeling from the transformation, struggled to comprehend the full implications of her new existence.

Samus vaguely heard the sound of the sliderdoor opening behind her and she turned around seeing a feminine horse clad in shiny white spandex approaching her, hooves clicking like heels on the metalic tile floor.

With a fluid motion, the operator's gloved fingers flew across the console, her slender form framed by the soft glow of holographic displays. The screens cast an ominous light on her face, illuminating the subtle curves of her equine features. Her eyes, shining with a hint of artificial enhancement, reflected the data streams dancing across the monitors.

"Wh..who are..you?" Same muttered, speaking now strange and unfamiliar as she needs to relearn it with her newly shaped mouth and enlarged tongue.

As the operator worked, the air was filled with the acrid tang of disinfectant and the faint hum of machinery. Samus's nostrils flared, her sensitive equine senses recoiling from the antiseptic scent. Her mind, still reeling from the transformation, struggled to reconcile her new instincts with the fading memories of her human past.




Strapped in
The operator hums a melody to herself before turning her attention to Samus. "Let's get you strapped in shall we?" The words throb in her head but Samus can feel herself nodding at the anouncement.

The operator hums a melody to herself before turning her attention to Samus. "Let's get you strapped in shall we?"

The words still throb in her head but Samus can feel herself nodding at the anouncement.

The woman in latex strutted over to Samus and picked up her hand to guide her towards a dentist chair. With a gentle yet firm touch, the operator secured padded restraints around Samus's forelegs, the material moulding to her new equine shape with a soft click. The restraints further locking into place with a series of metallic clicks. Samus's chest heaved with each laboured breath, her ribcage straining against the reinforced straps as she struggled to adapt to the unfamiliar sensations as a mechanical arm descended from the ceiling.

Its surface glinted in the soft light as a slender probe extended, its tip coated with a thin layer of clear gel.

The arm's gentle hum filled the air, a stark contrast to the turmoil brewing within Samus's mind. Before she could ask she heard her suit rrrrrip as the woman had torn a hole in the area of her crotch, samus nickered softly as the cold air of the room tickled her coochie while the mechanical arm repositioned.

As the mechanical arm drew closer, its probe glinting under the sterile lights, Samus's anxiety spiked. Her nostrils flared wide together with her eyes as her ears pinned back in distress.

With a panicked snort, she lashed out at the operator, her hooves striking the metal cuffs with a loud clang. The impact sent a shockwave up her legs, but the restraints held fast.

The operator's expression remained serene, her voice dripping with honeyed condescension. "Easy, dear," she cooed, her gloved hand stroking Samus's trembling flank. "No need for such agitation."

Her touch was calm and soothing, but Samus's instincts screamed at her to struggle, to break free from the restraints and flee from the ominous machinery looming over her yet another voice, louder, claimed dominance in her mind, "SUBMIT".

With calculated gentleness, the operator's fingers worked the restraints, each subtle adjustment sending a ripple through the straps. Samus's trembling intensified as the cuffs constricted, the hissing of the auto-adjusting material a stark counterpoint to the operator's soothing tone. The woman's breath, sharp with a hint of synthetic mint, caressed Samus's ear as she whispered, "Just a little pressure, precious one..."

A sharp click-hiss pierced the air as secondary clamps sprang into place along Samus's hindquarters and waist, the metal embracing her dappled fur with unyielding precision. The sound sent a shiver coursing through her frame, her eyes darting wildly as she struggled to comprehend the unfolding procedure as the chair started bending her forward with her rump sticking out, her tail flicking eagerly behind her despite her mind screaming both YES and NO!



Further Submission

As the probe descended, its gel-coated tip sparkled under the laboratory lights, casting an eerie glow on Samus's trembling form. A faint tremor ran through her body as the device made contact with her exposed flesh, the metal's chill seeping into her skin. A soft, anguished whine escaped her muzzle as the probe's gentle pressure deepened, the gel leaving a tingling sensation in its wake.

The operator's gloved hand continued to soothe Samus's flank, her touch a stark contrast to the mechanical device's deliberate invasion. "Let go, dear," she whispered, her voice a gentle, persuasive melody. "Allow the procedure to progress."

Samus's legs quivered, her hooves scraping against the floor in a futile bid for freedom as the probe's rhythmic pulses synchronized with the AI's distant, chiming instructions. The sound sent a shiver coursing through her frame, her eyes darting wildly as she struggled to reconcile her body's surrender with the turmoil brewing within her mind.

The operator's smirk deepened as her fingers danced over the restraints in a mocking gesture. Samus's breath caught in her throat, the padded cuffs now digging into her fur, the pressure a hair's breadth from becoming unbearable. "All secure," the woman murmured, her gloved hand administering a series of slow, measured strokes along Samus's flank in sadistic mockery.

A shiver coursed through Samus as the probe's tip pulsed with a gentle, insistent rhythm. The operator's free hand drifted up to the base of her equine ears, her fingers tracing a soothing pattern that sent a contradictory spark of tension through Samus's hind leg. The conflicting sensations left her feeling trapped and vulnerable, her mind struggling to reconcile the dual desires for resistance and surrender.

"Just let go.. give in.. simply enjoy. It's what you are made for after all" the equine woman cooed in her twitching ear.

As the restraints constricted, the padding dug deeper into Samus's flesh, eliciting a muffled cry from her throat. The operator's warm breath caressed her ear, her voice a gentle whisper. "Almost there, darling. Just a bit more." Her fingers were dancing along Samus's spine, tracing the tremors that coursed through her body. The probe's pulsing rhythm intensified, its gel-coated tip spreading a warm, tingling sensation through her core.

Samus's legs thrashed wildly, her hooves scraping against the floor in a futile bid for freedom. Her tail whipped back and forth, its frantic twitches a testament to her growing distress.

The machine's hum deepened, its vibrations resonating through her body as the operator's soothing words seemed to weave a dark, hypnotic spell around her.

The operator's grip grew firm, her fingers closing around Samus's flank with a sudden, possessive intensity. The sweetness in her voice curdled, giving way to a low, menacing whisper that sent a shiver coursing through Samus's frame. "Resistance is... stimulating," she hissed, her breath a cold caress against Samus's ear.

SLAP.

A sharp slap on her ass was enough to send her over the edge, her legs quivering with need and frightful obedience.

As the probe delved deeper, its pulsing rhythm harmonised with the AI's detached, melodic instructions. The gel coating Samus's inner walls had transitioned from a soothing coolness to a scorching heat, igniting a fire that spread through her core with alarming rapidity. Her thighs quivered, hooves scraping against the floor in a desperate bid for traction as the chair tilted her further forward, leaving her utterly vulnerable and exposed. Another clamp secured her tail out of the way to fully expose her nethers for the operator to admire.



Bred by machine

The operator's grip constricted, her voice laced with sadistic delight as she whispered, "The more you resist, the more exquisite the submission." Her fingers sank deeper into Samus's flank, just shy of becoming agonising, as the probe's pulsations accelerated, the scorching heat of the gel coursing through her trembling core like liquid fire. Samus's breath caught in her throat. Every instinct urged her to thrash, to wrench herself free, but the restraints held her fast, her hind legs splayed wide, hooves jerking spasmodically against the polished floor.

A second mechanical arm descended, its sleek, articulated surface glinting under the sterile lights as it positioned itself between her thighs, its presence a cold, unforgiving harbinger of the trials to come.

Unbeknownsed to samus this one was shaped like a horsecock, medialring and flare included..

As the mechanical arm's flared head made contact with Samus's entrance, a shiver ran down her spine. The cold, unyielding surface was a jarring contrast to the intense heat building within her.

While the other arm had withdrawn this one instantly shoved itself in up to the halfway mark. A strangled cry escaping her muzzle as the medial ring caught against her delicate folds, forcing them apart with an unnatural stretch. The flare's sudden, insistent pressure against her cervix sent her body into a violent spasm, her back arching against the restraints as the padded cuffs dug deeper into her fur. The sensation was both agonising and exhilarating, her muscles clenching around the invading length in a desperate attempt for control.

The lenght started pistoning in and out of her folds, her clit winking with need, throbing with understimulated desire as the medial ring rubbed up against it each time the flared cockhead nudged her cervix coaxing another whinny from her lips.

The operator's grip tightened further to posessive, her breath a scorching whisper against Samus's ear. "You're doing so well," she cooed, her voice dripping with sadistic pleasure as the mechanical horsecock continued its relentless assault. Each thrust was a masterful blend of agony and ecstasy, the medial ring teasing Samus's engorged clit with every withdrawal, sending shockwaves of overstimulated sensation coursing through her trembling form.

As the machine pistoned deeper, Samus's legs thrashed wildly, her hooves scraping against the floor in a futile bid for leverage. The restraints held fast, keeping her splayed wide, her tail clamped firmly in place, leaving her utterly at the mercy of the operator's twisted desires.

As the machine's relentless rhythm pushed her to the brink, Samus's body began to betray her, her muscles shuddered and surrendered to the torrent of sensations. Her thighs quivered with each thrust, her breath coming in ragged gasps as the medial ring's gentle caress ignited sparks of pleasure that danced along her spine. Her muzzle slackened, her tongue lolling between teeth, as her equine nature wrestled with the last vestiges of her human resolve. A strangled whinny escaped her lips, the sound torn from her very core as the machine's pistoning motion reached a fever pitch, threatening to shatter her tenuous grip on reality with a force that met the barier of muscle, her last line of defence for her helpless womb.

The operator played with her fingers on Samus abdomin, right on top of her ovaries as she occasionally leaned in further to whisper sweet nothings in her ear.

The operator's fingers bore down on Samus's abdomen, her nails etching deliberate, sinuous patterns that seemed to reverberate deep within her core. Each touch sparked a fresh cascade of tremors, as if the woman's fingertips could exert a subtle, insidious influence over the organs the machine was probing.

As the mechanical horsecock drove deeper, its flared head continuelesly grazing Samus's cervix with unyielding precision, her body responded with a mixture of anguish and longing. The medial ring's gentle abrasion against her engorged clit drew a fractured gasp from her lips, the sound torn from her very being as her senses teetered on the brink of collapse.

Finally with a mighty shove it settled against the barier to her womb, the artificial urethra lined up perfectly as thick spurts of arteficially enhanced sperm shot up into her birthchamber.

As the artificial seed surged into her womb, Samus's body shuddered violently, her throat constricting around a series of strangled whinnies. The operator's fingers pressed deep into her abdomen, tracing the swollen contours of her uterus with deliberate, almost clinical precision. A low, husky purr rumbled in her throat as she whispered, "Perfect. Every last drop, exactly where it's needed."

The mechanical horsecock remained lodged deep, its flare locked firmly against her cervix as the final, viscous trickles of the artificial seed drained into her. The machine's rhythmic pulsations slowed, then ceased, leaving an oppressive silence in their wake. Samus's chest heaved, her lungs burning as she struggled to catch her breath, her senses reeling from the aftermath of the intense, mechanical assault.
