Lotte admired her reflection in the mirror, eyes drifting from the tight, latex collar that had transformed her, down across her feline form. The collar’s magic had sculpted and shaped her body, bringing out her inner female form, and manifesting latex clothing from her body. Tight, sexy, seductive; the latex was as much a part of Lotte as her fur, impossibly tight and revealing. All wrapped in a harness, an extension of the collar wrapping around her chest. Even her shoes were a part of her, down to the stiletto heels.



        The changes weren’t just physical, the collar subtly weaving its magic into her mind, drawing out her innermost desires. Being wrapped in tight latex, her body on display, collared and harnessed felt good. Damn good.



        Something caught her eye in the mirror, a crimson curtain behind her, cutting off a restricted part of the store. It was open slightly, perhaps left accidentally by the werewolf shopkeeper, and Lotte could see the shelves beyond. Each was laden with rows of collars, cuffs, harnesses, leashes, and myriad straps of leather and latex. Her hand subconsciously reached for the collar around her neck, fidgeting at the edge where latex blurred into her fur. If the collar would turn her into this, what else could those do?



        Curiosity got the better of her, and Lotte sneaked a quick glance around her, easily spotting the orange-haired wolf several aisles away. Careful to quiet her steps, Lotte snuck behind the curtain, pulling it shut behind her.



        Hands ran across the collars. Some were latex, some leather, some a bit of both. Many were like hers; simple and plain and hiding their magic. Others were more elaborate, studded with spikes and fitted with bone-shaped tags, gleaming metal rings with sturdy locks, and pink collars glittering with gems. Further in were harnesses of all kinds, tangles of straps and buckles, and cuffs dangling from chains. It was an item at the end that captured her attention. A bridle, short straps of toughened rubber, sturdy rings and rivets securing it together, and a gleaming metal bit shining in the light.



        Lotte lifted it from the shelves, awkwardly disentangling it from the nest of other straps and harnesses. Metal chimed against metal as she pulled the bridle free, holding it out in front of her. It looked, at least as much as she could tell, just like a horse’s bridle except built for a shorter face, and perhaps with a few extra straps. Her heart fluttered with excitement, desire welling within her as she held it up, spreading the straps apart, and pointing the bit ahead of her. Slowly, almost reverently, she slipped it over her face.



        The straps fell against her face, the metal rings catching and rubbing against her fur. The weight of it was oddly soothing and satisfying, hinting at just how good and tight it would feel wrapped around her face. Hands fumbled behind her, slipping a strap through a buckle, pulling the whole thing tight around her. Another tug, pulling the strap to its limit, and the bit slipped up against her lips, the cool metal tantalisingly out of reach.



        Lotte’s disappointment didn’t last long.



        Slipping out from the bridle, twin straps snaked down either side of her neck, looping themselves into her collar, the magics of both bridle and collar combining into one. A familiar warmth spread out from the collar, a tingling feeling of pressure growing in Lotte’s head. The straps seemed just a little tighter, pressing into her fur and flattening against her skin.



        Another heartbeat, a surge of heat. The pressure grew, and Lotte’s head grew with it. Her face pushed out slightly, a sensation like she was falling into the straps that now crossed over her forehead, running down her cheeks, pulling them tight against her face. The bit slipped into her mouth, an inch at a time, running under her lips and over her teeth.



        The heat flashed again, bones popping in her head, jaw pushing ever forwards. The straps tugged again, those behind pulling through her fur, snapping tight against the back of her head. The bit slipped further in, working its way closer to the edges of her mouth. Nostrils flared wide, stretched out slightly over her growing jaw, vision shifting a little as the subtly-equine muzzle started to fill the space between her eyes. They moved out to the sides, more of the storeroom coming into view around her, though sacrificing depth perception around her. No longer the vision of a predator, but prey.



        Hands reached up, carefully feeling along the edges of the straps, probing the edges of her changing face. It was still unmistakably feline, but there was no denying the hint of a horse, all the better to fill out the bridle. Her fingers caught the edges of her ears, higher and floppier than before. The magic was drawing them out, smoothing and flattening them, the tip of each stretching out to a tapering point. They instinctively flicked this way and that, catching sound from around the shop: the murmur of customers, the soft clink of bottles, something prowling about in the rafters.



        The tightening straps ran awkwardly through her hair, strands of teal caught under the black latex, bunching and sticking out. A small portion of the bridle’s magic weaved its way through her hair, starting at either side and working upwards. With a faint glow, her hair vanished, leaving the straps resting much more comfortably on her patterned fur, letting them slip tighter still. Only a band of hair remained, running across the top of her head. Brilliant teal hair cascaded down one she of her head, mimicking a horse’s mane, running back to the thick braid falling down the back of her neck.



        The heat emanating from the bridle intensified, and pressure with it, her face surging forward again. Finally, the metal bit slipped through, settling itself in the corners of her mouth. Her teeth shifted slightly, making room, clamping down securely around it. The straps were pulled to their limit, so tight that they started to sink into her fur. Becoming one with her, just like the collar; fur and latex mingling together.



        “Wow…,” Lotte grinned, the word awkward and muffled thanks to the bridle. She ran her broad tongue across the cool metal of the bit, now snug in her mouth, anchoring the bridle to her. Fingers ran across the straps that were now just another part of her face, tugging even more tightly as she smiled.



        The wave of heat rolled down her body, a tingle running across her skin. Where her head had felt tight, constrained by the bridle around her, the rest of her body felt suddenly… free. The latex clothes that had once hugged her body relaxed, tingling as they melted into liquid. Lotte looked down as her top melted away, tickles of latex running through her fur, vanishing like waves on a beach. Her skirt pulled back next, freeing her legs, her tights sinking back into her fur.



        Lotte braced herself against the wall, picturing what was coming next just before her shoes sank away. The once solid heels collapsed underneath her, suddenly dropping her height 3 inches, landing with a slight thud. The latex of her shoes slipped around her feet, revealing her toes, drawing back under her paws and… was gone. The only part of her old ‘outfit’ that remained was the tight wrapping of purple latex around her braid, falling between the bridle’s straps and cascading down her bare back.



        “Okay, magic bridle,” Lotte whispered to herself, “what are you planning next?” At least, Lotte tried to whisper to herself. Her lips and tongue ran awkwardly against the metal bit now stuck in her mouth; the straps of the bridle wrapping around her face, holding her mouth shut. She couldn’t help but smile, running her tongue across the metal bit, now warm in her mouth. Despite how tight and restrictive the bridle was, the sensation was oddly comforting. Reassuring, even; like the bridle was made for her.



        Her fur bristled with anticipation, an electric tingle of static travelling down from the bridle to the collar. Tightness grew around her neck, skin pushing outwards, the collar spreading out wider and thicker. Brushing fingers along it, the slick latex slowly became dull and soft, echoing the texture of the bridle around her face. A matching set.



        The prickling feeling across her skin spread down, a weight forming in her shoulders. Her skin began to transform, furred skin changing into latex. The effect was similar to her transformation before but made so much more intense by the thickness of the latex emerging. It started out with her skin swelling; not some natural, gradual rise, but deliberate and sharp-edged backs of swelling, pushing up below her fur. Lotte’s fur then flattened, as if pressed under glass by the rising skin, swallowed by the rising tide of inky-black latex washing ashore. individual strands pushed together, melting and merging into a single, smooth, gleaming surface. All the while her skin and fur alike darkened, rich red ochre and teal turning an inky back to match both collar and bridle.



        Two thick bands started to emerge, running both directions, over her shoulder blades and down towards her breasts. The beginnings of a harness, thick and sturdy, resting firmly about her shoulders, perfect for carrying the weight of loads on her changing body.



        Perfect for a workhorse.



        Deep black even in the bright lights of the store, more and more of her skin swelled, more fur matting together to form the black latex harness steadily taking shape. The weight of it was strangely intense, impossible to ignore as it weighed down her breasts, flattening them slightly. Soft flesh bulged out on either side, as the thick bands swelled under her nipples. Fingers tentatively reached for them, sending her heart racing as shivers of pleasure ran through her body. Rising on the black latex of the harness, each nipple stiffened, impossibly sensitive as the chill air played across them. Instead of turning black, each turned a bright silver, tugged and twisted by invisible hands. Working out wider, a rough D-shape, a hole slowly forming in each and drawing out wider as each settled as D-rings on the harness.



        As each D-ring settled into place, Lotte could feel parts of her latex skin tensing and drawing together. Tendrils of inky black rising out from her shoulders, intertwining, forming loops to match her transformed nipples. Soft latex hardened, black fading to gleaming silver, growing heavier, settling comfortably on each shoulder. Then, the same feeling again down her back, pairs of gleaming metal hardware ready for reigns, straps, or anything her master might desire to be clipped into them… perfect for guiding her along.



        The thought played across Lotte’s mind, the prospect strangely appealing, a sense of belonging and purpose.



        The harness continued to spread, the wide bands of solid latex hugging her body - it was part of her, after all - matching the curves and contours of her body. The straps embraced her body, reassuring and tight.



        As the changes progressed down her torso, the thick bands of the harness reaching below her breasts, the tide of black latex began to spread. Running out across her belly, tendrils of black reached out and around her sides, mingling together as they looped around her back. Gradually, this wide band of latex started to take shape, neat edges curving gracefully just below her chest, and just above the tops of her hips. A corset, hugging her body tightly.



        It squeezed her torso, latex skin shrinking and pulling together, growing thicker and smoother as it drew her waist in narrower. It gave her body hourglass curves, the feminine shape slightly at odds with the utilitarian hardness, yet Lotte knew it served a purpose, too. Already she could feel the heavy forms of metal hardware forming. Thick loops of metal, solid and sturdy, a pair hanging ready at either side of her corset, perfect for hitching herself to any cart or wagon her master might need pulling.



        Something stirred below. Spreading down from the corset, her flesh began to swell out again. Her legs quaked a little, her heart skipping, a rush of pleasure as the black latex rose out from her body - so much more intense than any change that had come before. Reaching down, gingerly, Lotte could feel nothing but the shape of the harness now running between her legs. It pushed the soft flesh of her thighs out slightly, encasing her ass as the latex spread back up to join the rest of her harness. Yet the slightest touch against the smooth latex almost brought her to her knees, and it was all Lotte could do to stifle a muffled moan in the storeroom.



        The changes reached up over her ass. Swelling, latex skin wrapped tight around the base of her tail, pushing out slightly as if anchoring it to her. Along the length of her tail, her fur bristled, quickly growing out longer - while the tail itself grew shorter. A pulling sensation deep within her body drew it backwards, changing her slender leopard’s tail into a more equine form. It flicked about, graceful curls of hair swishing behind her. Looking back over her shoulder, Lotte thought it a little odd, the thick band of latex around its base making it look more like it was part of the costume, not a part of her… just like the rest of the harness, she thought.



        With the harness now complete, Lotte took a moment to regain her composure, looking down at her body with a mix of admiration and anticipation. The harness at once alluring and revealing, yet perfectly utilitarian, her body built for work as much as for pleasure… though now she wondered if they were the same thing.



        Familiar pressures grew around her wrists, skin pushing out to form thick bands of latex, perfectly matching her collar… cuffs, of a sort, tightly gripping each arm. Then two more pressures, around her ankles, swelling and transforming to match. Though these had no rings, no fasteners, and no buckles. Each was a solid and unmovable part of her body, anchored firmly.



        A different sensation came next. Swelling, but oddly dull, numbing. Her hands started to swell all over, the soft flesh of her fingers pushing out into each other, squashing and flattening against themselves. Her palm swelled too, rapidly growing outwards between her fingers, sticking them together. She tried to flex them, her pudgy fingers struggling to flex. Her soft flesh just stretched as she tried to pull them apart, though with each second she felt them drawn back together more intensely.



        As flesh continued to swell, it became harder to tell individual fingers apart, all slowly lost in a rough marshmallow shape. As the swelling reached its limit, fur matted together into familiar black latex. Her palm, if it could be called that, finally stopped swelling as it pushed past the tips of her fingers, forming a near-perfectly flat surface at the end of them. The rest of her hand formed a smooth and rough cylinder, narrower at her wrist, with a clear edge around her palm. The shape was simple, smooth, but unmistakable: a hoof.



        Her wrist could still turn it this way and that, with a little stiffness as swollen latex stretched and crumpled, but it was impossible to move her fingers - if she even still had fingers under the thick mass of latex. Just about all she could do was squash them into things, maybe pick something up with both hooves if she tried really hard. Yet the skin was still characteristically sensitive like the rest of her, sending a thrill through her as she squashed them against her chest.



        Her feet shifted beneath her, bones stretching out awkwardly, drawing her feet out longer with them. Her heels began to lift again, though this time there were no solid stilettos under her to support them. It was all her body, warping and reshaping with the bridle’s magic. The same swelling that had overtaken her hands started to work its way down her feet. Faster, this time, working with shorter toes. They blended together, the edge of her feet pushing out into a perfect curve, the balls of her feet flattening out into a perfect hoof.



        Her heels continued to rise, feet still stretching upwards, fur turning inky black as it flattened into latex, stopping at her ankle cuffs. The rising feet forced her to shift her legs, bending them more at her knees to compensate, matching the look of a horse’s legs more and more with each passing moment. As her feet pushed out even higher, she shifted her torso slightly, pushing her ass out further behind her. She felt bones and tendons shifting inside, making the pose more comfortable, more natural. Muscles swelled and adjusted, thighs bulging with increased power. Flexing from hoof to hoof, she tested the power of her new limbs. A desire to be out there, running through the forest, grew within her.



        Lotte took a moment to study the changes, holding her behooved hands out in front of her, taking a few more steps through the store room. Each step echoed slightly, smooth latex slapping against the stone floor, a slight shudder of vibrations carrying up her smooth limbs. Yet, as oddly natural as her new limbs felt, Lotte knew to a regular observer they would seem like just another part of a horse costume: just strangely crafted gloves and boots fashioned after hooves. Then again, maybe that’s what they were, her whole self the embodiment of a ponyplay costume…



        Lotte’s ears flicked, swivelling to catch a sound behind her, the familiar pad of the werewolf shopkeeper, and her heart raced a little with primal fear — or was it anticipation?



        “Ah, I see you found our forbidden collection,” the witch’s voice called, tone heavy with amusement, shaking Lotte from her thoughts. Evie stood by the open curtain, a smirk on her face, taking in the sight of your more equine form.



        Lotte could just stand there, and blush, the bridle making speech impossible. Though, that felt right. She was just a working animal now, after all.



        Evie stepped closer, reaching out to Lotte. The air sparked between them, black reigns materialising, stretching out from Evie’s hand to Lotte’s bridle. She felt a sudden click, a slight weight pulling at the rings anchoring the bit running through her mouth. Then a sharp tug as Evie pulled on the rein, Lotte instinctively stepping forwards towards her.



        Lotte could feel her heart fluttering, something about the simple act of being pulled forward, of immediately obeying bringing a thrill of pleasure and satisfaction. If it weren’t for the bit running through her equine mouth, she would have been grinning, giddy with pleasure.



        “Good girl,” Evie smirked, clearly noticing - and enjoying - the effect she was having on Lotte. She slowly stepped around the latex ponygirl Lotte had become, taking in every part of her form. The shape of her body, now wrapped in that solid harness. The way her legs had shifted to accommodate her hooves. The blend of feline and equine features the made up her face. The way the bit of her bridle was solid and secure between her teeth.



        “Now, what will I do with you?” it was a question, but Lotte wasn’t sure she should answer, even if the bridle would let her. It didn’t seem right for a horse to talk, after all.



        “A harness like that, no bridle, you’re clearly not built for riding,” Evie continued, as Lotte gave the slightest nod. The idea of being ridden definitely had its appeal, but Lotte felt happy to do any work. Of course, Evie would just as quickly change Lotte again, fit her with a harness, and tweak the length of her limbs so they were more even, but Evie had a better idea, “maybe I should hitch you to our cart. It’s pretty heavy, but I’m sure you’ll manage nicely.”



        Lotte nodded, much more vigorously, hair cascading about behind her. Evie just smirked.



        “We used to head out to markets, village fairs, that sort of thing… bring a few of our more subtle magical items and potions to sell, but it always seemed a bit too much trouble. That was before we had a pony to help out, of course.” Another smirk, and Evie knew Lotte was enraptured by the idea.



        Evie paused a moment, looking over Lotte again, “though I think you can manage with just your legs for that…”



        A quick incantation and magic surged along the reins, a warm rush of electricity cascading through Lotte’s bridle and down her body. Her arms grew numb and sluggish, slow to move as Lotte stared down at them. The air grew bright with glittering motes of light, swirling about the end of each hoof. They began to drift upwards, hooves vanishing into the air as the spell worked its way along her arms.



        As her fore-hooves faded away, Lotte could feel her legs shifting slightly: Evie’s spell redistributing her mass, her strength. Muscles bulged under her skin, a warm ache spreading through them, growing thick and powerful as more of her arms faded away. Thighs pushed outwards, thick and powerful. Letting two legs perform the work of four. Under the corset, Lotte felt new muscles pushing outwards as the swirling magic reached over her elbows. Her chest rose out, muscles swelling, ready to support whatever load or cargo was fastened to her.



        Soon, the ache in her muscles died down, and all that was left of her arms was a slight bump at the end of each shoulder… but that was right, wasn’t it? After all, what would a horse do with arms?



        “Good girl,” Evie repeated, as if sensing Lotte’s thoughts, “another slight change, can’t have you getting distracted along the road.” Another cascade of magic, washing over Lotte’s face, concentrating just behind each eye. Another twinge of pressure, flesh pushing out, blinkers forming at either side of her vision. They blocked out everything except what was dead ahead: Evie, smiling warmly at the sight of her.



        She tried to turn her head to either side, take in more of the view around her, but something seemed to restrict her, holding her head steady. The collar, already grown thicker thanks to the bridle’s magic, was spreading up and down, covering more and more of her neck. Skin stiffed, changing to stiff latex, almost completely encasing her neck. A posture collar, resting just below her chin, limiting how much she could look away. Each movement the collar allowed seemed exaggerated, swinging her head from side to side like a real horse, her mane and braid swishing gracefully behind her. Her heart fluttered a little, the changed collar reinforcing both her role as a horse and how much she was under Evie’s control.



        “Come along, now, let’s get you harnessed up and ready for your test run.”



        Evie tugged at Lotte’s reins, a firm pull on Lotte’s bridle, urging her to follow. Evie kept pace ahead, Lotte trotting along behind, settling into a steady gait. The witch led the way, winding between shelves towards the back of the store. Occasionally, customers would notice, staring at the pair with mixtures of amusement, surprise, and occasional envy. Not that Lotte noticed, of course, the blinkers doing a perfect job of keeping her focused on the way ahead.



        Stepping through a door, Lotte squinted a little in the bright sunlight, gazing out into the Emporium’s small yard. The cart was already there, as if waiting for her, Lotte’s heart beating faster with anticipation.



        Evie guided her along, a firm hand nudging Lotte to turn around, facing away from the cart and staying patiently in place. Lotte’s ears twitched, hearing Evie busying about with the cart behind her. Then, fingers gripping the back of her harness, warm fingers brushing against her latex flesh. Evie carefully passed heavy straps through the D-rings at Lotte’s shoulders, fastening them with clips along their length, letting the rest of them fall against her chest.



        Evie stepped around Lotte, humming to herself as she worked. With a deliberate (if playful) roughness, Evie clipped the end of each strap into the D-rings that had been Lotte’s nipples, sending waves of pleasure through Lotte’s body. She shook her head slightly, a moan of pleasure escaping her mouth, almost like a whinny of delight.



        “Steady,” Evie commanded, only a slight smirk betraying how much she was enjoying herself. One after the other, Evie lifted up the cart’s wooden poles, carefully fastening each to either side of Lotte’s waistband. Satisfied with her work, she stepped back, watching Lotte gently shifting about, now firmly secured to the cart.



        Inside, Lotte was giddy with anticipation, the feeling of purpose and satisfaction growing within her. Growing impatient, she started to scratch a hoof against the ground, tugging at her reigns.



        “Steady,” Evie repeated, more firmly, deftly flicking the reins back over Lotte’s shoulders as she stepped up onto the cart’s footboard.



        “Okay, girl, let’s see what you can do.”



        Lotte felt a sudden flick of the reins behind her, instinctively urging her on. She stepped forward, latex hooves digging against the stony ground, pulling against the cart fastening to her body; more securely and intimately than any horse before her. The weight of it pulled at her sides, straps pulling tight and heavy against her shoulders, pulling back against her chest. The harness lifted slightly, pulling the soft flesh of her breasts with it, before the tension was caught by the clips at her shoulders: leaving just enough of a tug to tease her transformed nipples.



        A surge of sensations rocked her body as she stepped forward again, the wheels of the cart slowly turning behind her. Such visceral feelings of the weight of the cart pulling against her body, stone brushing against her latex feet.



        The pleasure and satisfaction of being a good pony for her mistress filled Lotte as she carried them both off into the forest…
