Katie is in the hardest bike ride of her life, but will a shortcut give her the winning edge or take her to a whole new set of "finishes"?

I put this together because I wanted to write something female-focused and that integrated my love of all things cycling! :)


The peloton passed Katie with the power of a freight train. There was nothing she could do as the click of gears and heavy breathing of her competition whooshed passed her on the long open stretch of highway. Legs burning she tried to push harder, the feather-light carbon bike under her felt like it weighed a thousand pounds. Sweat poured down her face and onto her top-tube, her sweatband already fully saturated from her earlier sprint.

"Arrghh...damn it...go! GO!" She screamed trying to force herself to pedal harder. Standing on her pedals her bike weaved underneath her thin frame, breaking the near-perfect straight line she was cutting across the grassy landscape. The watch on her wrist began beeping, she was red-lining, reaching her maximum and unsustainable performance. It just wasn't enough! She didn't need the watch to tell her she was exceeding almost two hundred beats per minute, her heart felt like a hummingbird's. If she sustained this for much longer she could die...or worse. Looking up she saw the group of cyclists, at least half a mile away now, weave around a cheering fan like a flock of birds and over a hill entirely out of sight.

She had to keep pushing, she had trained too long and too hard to give up now. Something wasn't right, she was stronger than this. Cursing under her breath, unable to sustain the effort, she sat back down on the seat. Her heart was still racing. Taking a swig from her water bottle she barely tasted the concentrated sports drink. Placing the bottle back into its cage on the bike she looked at her cycling computer, she was dozens of miles from the finish but it may have been an infinity symbol on the black and white screen suspended on her bike's handlebars. Leaning down and grabbing the low aerodynamic parts of the handlebars she tried to straighten out her body to try to lower her wind resistance. But her legs were shot. Hot wind whipped across the grassy plains on each side of her buffeting her, pushing her like an invisible hand backward from the direction she needed to go.

"GOD...FUCKING...DAMN IT!" She screamed between gasping breaths, nobody around to hear her cry. There were no options left. It was then she felt a familiar and unwelcome pressure in the top of her head. No. No, not now. She thought she had this under control.

"No..no...no, no, no!" She gasped in increasing urgency, the pressure in her skull only increasing. The helmet strap around her chin was tightening by the moment. She could tell her head was bleeding, the sweat carrying a diluted mix of her own coppery-tasting blood to her heavily breathing mouth. She didn't have to see it to know what was happening. With a series of styrofoam crunches and a throbbing pain like her skull was being operated on she could feel the horns bursting through the helmet's protective grip on her scalp.

"Nooahhhh!!!" Was all she could gasp as the dark bony horns elongated and twisted above her. The helmet somehow still structurally sound enough to remain atop her head. She had to stop, hide somewhere until she could control it, get it to go down. But then a thought struck her. It was crazy. But there was a chance. She had never let herself go that far in public before. She didn't even know if the mechanics would still work with her legs being... Looking at her watch there wasn't enough time to stop and let it run its course, she would have to keep riding through it all if there was any hope of placing. Realizing she didn't care how she finished she only wanted to finish. She had to prove to her girlfriend that she could do it.

Taking a deep breath she let herself go, it was like un-clenching a muscle or letting her belly out when she still had one that wasn't flattened by years of non-stop training. The changes started near immediately, unstrained they began to wrack her body. It was all she could do to keep her bike straight and keep turning the pedals. Organs and muscles were reshaping inside of her, growing and moving. It didn't hurt when she let it go so freely, but there were other parallel worries on her mind now.

Face extending, she moaned. The bridge of her nose was lengthening in front of her eyes, cracking and crunching, her jaw extending forcefully outward. It didn't hurt but it didn't feel good either. The skin of her face raced to accommodate the shifting bones. Nose broadening her lips turned black and rubbery. Running her tongue over her teeth she could feel them broadening, flattening, pushing out of her distended gums

The world went silent, her head filled with ringing as her ears shifted upwards on her head. They traveled under her sweatband before lengthening and bunching up under the damaged styrofoam lattice of the expensive racing helmet. Fumbling with her ears she realized that she couldn't get down under the helmet so she improvised and managed to extricate them through the large lateral vent holes in the top. The bike almost fell over but she managed to do it, near perfecting the technique with her left ear before moving to her right. The wind noise was sudden and sharp, filling her still-lengthening ears with the sounds of the gears below her and the open fields around her.

Her face had finally stopped its outward expansion, leaving her with an animalistic muzzle, covered in very taut pink flesh. Knowing it was just the start she braced for the rest. If there was one good thing it was taking her mind off the pain in her calves and lungs, but the miles were still trudging by. As if her body knew where she needed the most help her thighs began to swell against the lycra of her bib-shorts. Sinewy muscles compounded and heaved under her skin. The aches and lactic acid built up from the long day of riding were no match for the changes rippling in her legs.

"Garghh...ahnnn!!!" Groaning she gripped the handlebars as widely and as tightly as she could to give her some modicum of stability against the wracking muscle spasms making their way through her legs. The grippy bands around the cuffs of the bib dug into her flesh. The tendons connecting to her knees swelled immensely, making the black lycra hugging her thighs near transparent in the process. The changes surged down her legs, her bones widening and becoming denser to support the increased strength. Her bare calves bulged, the muscle growing so fast she could feel her skin tighten around them like a rubber band before catching up.

"Uhnnn...Ok let's see...what you things can do!" She managed to gasp as the muscles around her legs settled. The fatigue was gone now, she felt so strong, so powerful. It didn't matter that her bibs were so tight around her thighs that they threatened to cut off circulation, the hard mass of her leg muscles wouldn't let that happen. Pushing down on the pedals she was suddenly rocketed forward. The bike's deep carbon-fiber front wheel lifted off the ground a couple inches with immense torque before landing again. So focused on her changes she had barely noticed that she had come to a steep incline. Hammering up the hill she barely had to stand and was actually feeling refreshed at the top instead of winded.

"Ok...I can do this," she said to herself with a smile. She just had to stop the changes there, it would be enough to at least let her complete the course. It was easy to explain away some overstretched bibs and a broken helmet. Nobody would even notice her face if she moved fast enough and kept her head down. Trying to re-clench the beast she was rebuffed. Trying again it pushed back harder.

"No...no please, that's enough," she tried to bargain, pleading with her body. But it wasn't a thing, it was her, a part of her she never wanted anybody to see. And now it wouldn't be put down as hard as she tried. Her body was wracked with more internal changes, it felt like somebody had punched her in her stomach. Catching herself on the lower parts of her handlebars she barely had time to react and keep herself from crashing into a berm.

"No....I can't...please...." She moaned through her elongated jaw, more unseen changes were happening, her back cracking and crunching so badly that she had to raise her behind off the seat before plunking it down painfully onto the narrow hard racing saddle. Her vagina pulsed against the padding of the bibs. No. This was the wrong place and time for this. She tried harder to push it back down but it only rebounded stronger.

Her petite pussy convulsed, throbbed between her legs. Her heartbeat began to thrum in every inch of its non-existent rise. Writhing on her seat she tried to press her thighs together over it but it was useless. With a pinching, tingling sensation she could feel herself growing thicker. The flesh of her shaven lower lips swelled with every pedal rotation of the bike's pedals.

"Uhhh...Ahnnn!!!" She moaned, her sun-burnt face growing somehow even more flush. Unwelcome wetness erupted inside of her, sickening her inner folds. Katie could feel her love canal growing wider by the moment, her normally near-unfindable clitoris growing under a stretching hood of flesh. Her womanhood pressed into the padding of the bibs harder and harder, forcing her lower lips open, dragging her pronounced clitoris against the lycra. More wetness grew inside of her and spilled out into the bib. Looking down between her thighs she could tell the chamois was absorbing what it could. Sighing in relief she was about to look up again but noticed that the slick fluid had overflowed and was now straining through the fabric of her crotch. Her labia pulsed and grew again, pressing against the fabric giving her a pronounced camel-toe. A deep desire, what she could only describe as horniness, flared in the pit of her stomach. Thoughts of her girlfriend's pussy touching hers, her delicate fingers spreading her open filled her head.

"No, don't...not now...I can't! I...I....uuhhnn!!!" Moaning lustily she could feel her pussy deepening, burrowing into her body. It felt good. She couldn't deny it as much as she wanted to. It felt better than good. Without thinking she began gyrating her hips, pressing her lower lips into the nose of the bike seat. The bones of her pelvis were shifting and cracking now, her boyish straight-as-a-board figure cultivated from years of power-to-weight training was being destroyed. Hips widening with a sickening series of cracks Katie could only grind her teeth, she had hit a downhill so all she could do was steer the bike and try not to crash as her body rebelled.

The stretchy bibs were hitting a breaking point, the widening of her hips wasn't stopping, her pelvis growing to accommodate a massive baby. Pussy lips pulling apart by the stretching skin she couldn't help but issue another gush of fluids from between her legs. Swelling further, her cunt's muscles were clenching and strengthening, giving her a pronounced mound. Lycra began to tear across her thighs which were thickening again. Feet crunching, her toes curled on themselves in her expensive carbon-fiber-soled cycling shoes. With nowhere to go her heels pressed out of the fabric and extended upward. The bones and sinews of her foot tendons stretched and twanged like piano wire. Thickening bones shed much of their fatty tissue.

She couldn't see it but she knew what was happening in the immensely tight shoes. Hooves. Katie could feel the unwanted keratin pouring out her, coating her spreading toes. Bursting through the tips of the shoes were the ends of two cloven hooves. Hooves that were growing larger by the second. Reaching down to undo the velcro from her shoes before they burst she was only partially successful, even undone her hooves were too large for the shoes by at least double. Groaning in discomfort as much as the destruction of her four-hundred dollar cycling shoes she managed to strap the velcro back down enough to keep her new animalistic feet in place and pedaling

The heat was getting worse, her pussy throbbed incessantly between the pistoning motion of her thighs. Shocks of unwanted pleasure emanated from the thickened nub of her clit making her swerve all over the road. Too distracted by the pulsing need growing in her loins she only noticed her ass cheeks as they began to tingle.

"Uhh...Uhhhhnnnn!" Was all she could grunt out as all her precise calorie-counting and dieting was undone in mere moments. Fatty tissue expanded and piled onto her rear cheeks, pulling her bibs somehow tighter. Looking between her legs she could see the pink of her engorged fleshy lower lips through the fabric it had become so thin. Before long she was sporting an expansive spherical butt that jiggled with every bump and small divot in the road. The bibs fell into the deep well between her rear cheeks driving her wild, pressing against her anus. The walls of her vagina shuddered hard, issuing enough of her sweet-smelling lubricant that it began to leak down her bike's seat post. She was going to cum but she was about to steer into a series of switch-backs down the mountain. With all the willpower she had she forced the climax back down. Neck straining she tried to concentrate on the route, but her body was making it near impossible.

Somehow she made it down the mountain, her downhill speed incredibly fast with the increased mass atop the bike. Relaxing for a moment she moved her white-knuckled hands from the drops to the top of the handlebars. She had to undo this somehow. But there was no time, the clock on her bike computer readout that there was only about an hour left in the race at the pace the peloton was setting. Her calculations were superseded by the heat between her legs. Her pussy begged to be touched, but it was impossible while she was riding, which only drove the sensitive nerves of her flaring womanhood more insane. The changes had spared her while going downhill but thinking about the need in her loins only brought on the next wave. Everything was out of order, it never happened like this before.

"No...Huhhhnnn please... my back!!!" The nerves in her back pinched as vertebrae ground against each other. Spine thickening below her skin, it managed to grow long enough that it pressed out of her just above her copious ass cheeks, growing into a slender hairless tail. It was trapped pointing downward by her bib.

"Huuhnnn.. tiiiighhttt..." she whined, teeth grinding. Katie hardly noticed her voice had lowered several octaves. Her lower body had taken the cycling garment far beyond the extra-small size it was intended to contain. With a great tearing noise, her bibs finally gave up the ghost. Flying to pieces scattered along the roadway behind her as the garment tore along its stitched seams. Now freed, her thighs ballooned with additional fatty tissue, making them grow thicker and more pronounced.

Her inner thighs rubbed now when she pedaled. The only thing still attached to her of the expensive cycling garment was the leg stabilizers which now acted like make-shift thigh garters and the flapping mesh overalls that wrapped around her slender shoulders. The chamois pad was still held in place by her body's weight, if she stood it would fly off too. The soaked piece of blue padded foam the shape of a menstrual pad was all that was preventing her engorged dripping pussy from touching the bare seat of the bike. Looking at her crotch she could see inside of herself, her soaked snatch looked huge, its folds gaping from need and buffeted by the hot summer wind.

Looking at herself was a mistake. Visibly clenching her erotic pussy oozed slickness. She felt like a voyeur for her own body. Shuddering tried to look away before it was too late. Before she could divert her eyes her inner walls squeezed against each other, slick with lubrication re-soaking her entrance. Without thinking, near-instinctually, she ground her wide hips against the seat again eliciting an animalistic moan from deep in her chest. A clit the thickness of her pinkie, red and throbbing, stood at attention above her opening. Vagina clenching again, harder this time, her thighs tensed, stopping their pedaling motion leaving her in a rolling coast. Her rear hub buzzed loudly behind her, egging her to keep going. All her training told her to not let that sound happen, when the rear hub sounded she was being lazy, not pushing hard enough. But her training wasn't enough in the face of this. She couldn't hold it back, as much as she hated to admit it she needed it so badly. Her body was on fire, every muscle tensing.

So desperate for her spasming pussy to be touched she moved her hips off the seat of the bike and tried to use the top tube to spread her dripping lower lips. Straining to keep her body upright at such an unnatural angle her powerful digitigrade legs shook. Grunting in frustration she was barely able to drag her soaking labia across the tube before the tension in her thighs became too great. Despite the failure, the touch of the inert carbon against her clit was just enough to take her over the edge.

"AHH NUUUHH!!!" Head thrown back she issued an ugly animalistic below, her pussy squirting a misting of juices across the front of the bike, soaking her bare thighs. Her wide flat teeth bit her lower lip, her head whipped downward, pressing dangerously close to the front tire of her bike. It was all she could do to hold onto the handlebars as the pleasure rolled through her body. Shudders and aftershocks wracked her increasingly voluptuous frame. For all the rapturous pleasure it was a hollow climax, she felt a deep ache still inside of her, needing to be filled.

Her pussy's entrance was soaking, the flesh quivering under her. Regaining some composure after gliding to a near-stop she managed to pedal enough to keep forward movement going. She had never squirted before, that was something she saw in porn videos... even like this, that just didn't happen, not to her. The dripping slickness that coated the entire cockpit of her bike said otherwise. She could smell herself everywhere, her sex was pungent enough with her sensitive nose but the slick fluid dousing her bike was driving her mad. More thoughts of her girlfriend atop her, their balmy flesh touching. The horniness roared back with a vengeance, her body told her it wasn't enough. She needed more.

Head pounding she managed to look up again, her cycling glasses, which had somehow held on all this time fell from her face, crunching onto the hot black pavement below. She couldn't stop for them. The afterglow of the orgasm gave her a massive boost in speed Gasping for air she pushed forward, her legs propelling the bike at maddening speeds. Fingers spasming she up-shifted her gears, she was maxing out her normal climbing gear, her legs spinning like mad. Her knuckles crunched even as she held onto the hoods of her shifters for dear life. Her hands were growing in size, their petite fingers thickening before her eyes. Soon her hands were almost entirely compassing the shifters that she had specially sized for her diminutive five-foot frame. The tips of her fingers ached. She could only hold on while keratin pushed her fingernails from their beds, replacing them with thick hoof-like slabs. Ligaments in her arms tensed and spasmed, putting on mass and strength. She felt like she could rip her handlebars off the bike if she tried.

Distracted by her hands she felt the torn padding of her cycling bibs manage to worm themselves out from under her, flipping away, caught by the wind before landing wetly onto the road.

"No oh shiiittt...UHHHNN! Nuh...uhnnnn!" She cried out before moaning in pleasure. Her now unprotected pussy pressed into the nose of her saddle, her engorged lower lips spreading to let the hard synthetic material of the bike seat sink inside of her. Trying to extricate herself only made her hips grind against the tapered end of the seat, dragging it against her throbbing clit. Pleasure shocked through her frame, she wanted more despite herself. Fresh wetness gushed from her vagina, soaking the seat that ground against her entrance. Her full body's weight was pushing against the hard surface, so desperate for the touch of the inert object inside. But it could go no further. Grunting like an animal in heat she almost came again. As she ground herself needfully she kept cycling, faster and faster. Her thighs slapped each other, lubricated by her own love juices.

"FUCCCKK WHY WON'T IT STOPPHHNNN!!" She moaned as creamy white follicles pushed out from the rise of her lower lips. The new fur already sopping wet, absorbing the clinging slickness that soaked her nethers. The feeling of the fur pushing out of her sensitive lips was all it took to take her over the edge again. Bucking wildly on the bike it jerked forward, her pussy clenching like a fist. The squirt of juices from between her legs wasn't a mist this time, it was a veritable torrent. Slick love juices sprayed over her already saturated bike, soaking into her purposely thin bar tape. Accelerating with her climax the fur crawled up her torso and down her legs in concentric spirals. The pelt wrapped around her jiggling ass cheeks, their flesh swelling further as Katie moaned.

"HUHH...HUUH...AHNNN!!" She grunted with every shock of rapture through her throbbing entrance. The waves of the orgasm wouldn't stop ravaging her. The fur wrapping around her waist transitioned to a light brown, a dark stripe of black cleaving the border between the two colors. Diving between her thick thighs the dark line wrapped around her now pronounced ass cheeks. The dark stripe soon met her tail, flicking and extending in length behind her the fur crawled up its length, sprouting long coarse strands from the bony protrusion. Every strand pushing from her darkening skin felt like it was extending her climax. Thoughts of her girlfriend gyrating on top of her, her cute clit dragging along her stomach leaving a small trail of wetness down her stomach almost made her white out. The bike wove dangerously below her, her legs not stopping for a moment but her ability to steer severely impaired by the shocks of euphoria lancing over every sensitive nerve. Her pussy slammed into the bike seat over and over desperately trying to insert more of its aerodynamic length inside of her but it was no use, the flaring tail of the saddle was far too big even for her dramatically larger entrance to take.

The quiet revving sound of the gears below her changed, her dusty chain finding new lubrication from the dripping faucet that was her vagina. Looking down with lust-lidded eyes she could see her juices had coursed down her seat tube and were actively dripping onto the front rings of her bike. Nose flaring she smelled her own sex over the bike's sculpted frame. Even though she was still feeling aftershocks of her last orgasm she felt the need to cum again, the ache was still so bad. Shuddering, she let out a plaintive moan, the seat plucking at her engorged lower lips. Despite her best efforts to push down the thoughts she desperately wanted to feel something, anything inside of her. She couldn't help being entranced by her own lubricating juices still slowly trickling down the carbon fiber, tongue extending from her mouth she wanted desperately to taste it, but the heat of her sex was frustratingly far away.

Without warning her body jerked upright by an unexpected spasm in her back. Head craning skyward her ribs began to crunch and thicken in her chest, barreling outward one at a time. Her already boyishly flat breasts were flattened by the swell of her torso. Skin stretched thin over protruding bones.

"Noooahhhh! Ffff...uuuhnnn!!!" Groaning in discomfort her light lycra jersey tightened around her shoulders and arms. Breathing rapidly her breath caught in her throat. Gasping for air she could feel her lungs growing larger in her chest vacuuming up the hot air swirling past. Recovering her senses with the huge infusion of oxygen her mind cleared enough to notice the tightness of the form-fitting top. It was unbearable. Grimacing she fumbled for the zipper, even its pull was designed to be aerodynamic and was tucked into a small pocket near her neck. The thickness of her fingers and their protruding black nails made it near impossible to extricate. The jersey was getting tighter by the second as more bones crunched in her chest, her shoulders widening, sending her arm shooting out in a spasm. Tugging madly at the collar of the jersey was fruitless, it was too expensive and well made to be undoable so easily. Returning to the zipper she managed to finally goad the pull from its shelter and yanked downward with abandon. Managing to unzip the front of her jersey she let out a great sigh.

"Too tight, uuhnn...I can't..." she moaned through labored breaths, her newly efficient lungs couldn't help her. To add to her discomfort she felt her shoulder blades extending behind her, the twinge of them growing against the skin of her back distracting her from the ache between her legs. The unzipped jersey provided only temporary relief to her swollen torso. The remaining straps of her long destroyed bib unfurled from over her shoulders like frayed streamers. They dragged behind her for a moment before being caught by the wind and whisked off to join the rest of her ruined bib shorts somewhere along the course. Flapping in the wind her jersey hugged her shoulders and arms, the only things keeping it attached to her body. Despite it all, she cut through the wind with a terrifying pace. The muscles in her legs felt stronger with every change. Legs rotating faster and faster, the miles whipping by. Heart beating rapidly through the rise of her pussy lips she felt the need growing with every small hill she sprinted up and blazed down.

Her sports bra was still firmly wrapping her body, nearly cutting off the circulation of her chest. Fur radiating from her stomach was already making its way up her chest and around her back, stuffing the stretchy sports bra. Its usefulness was normally minimal but she felt naked without wearing one when cycling. That decision was coming back to bite her now. To add to the pressure an immense pressure began to pool and build behind her small nipples.

"Not my tits...not my tits! I...I..." She gasped, one hand letting go of the bar just in time to grip the swelling rise of fatty tissue building underneath the bra. Her entirely flat chest began to grow in definition atop the distended rise of her ribs. Without slowing the fur had already coated her chest and was rapidly crawling up the tensed rise of her neck. Head straining forward she tried to stop the changes, there was no way for her to remove her sports bra while in motion. Teeth clenching, spittle sprayed from her mouth. The need to be complete was too great. The heat. Oh god, the heat. It was everywhere. Throbbing through her nerves it was impossible to push down anymore. But she had to try. She could see the peloton in the near distance, the group of riders weaving through the landscape like a snake.

Tickling the underside of her muzzle it spread over her elongated head rapidly. Imagining this is what growing a beard must feel like she could only keep her mouth clenched as the fur pushed out of her. Creamy white fur coated her lower muzzle while a stripe of brown fur made a beeline for her nose. The same thing was happening to her arms, white fur underneath and brown fur on top. Shivering at the sensation of her body extruding the sleek pelt she knew it was almost over. Her eyes caught the edges of her distant wide pink nostrils as they turned black. The pressure in her bra decreased, leaving her with two barely noticeable mounds of flesh, not even enough to fill the cups of the smallest of bras. Snorting in air she let out a sigh.

"It's over...it's over..." she repeated, barely a whisper, disbelieving. The heat remained but for the moment it felt noticeably more manageable.

Concentrating on the riding for the first time since the changes began she really put the pedal to the metal. The deep rims of her wheels whirred through the air with a speed far in excess of anything they were designed for. Her watch beeped, asking her to turn off ride tracking while in the car. Smiling she accelerated faster, standing on the pedals with shaking, unsure legs she soon found her cadence. The carbon flexed below her, the overbuilt bottom bracket where the crank attached to the bike no match for the power her legs were pouring into the two-wheeled machine. Powerful heart pounding it felt like she still had power to spare. The gears were screaming, she had maxed out the highest gear on her already very-highly geared racing bike. The only way to go faster was to spin at some inhuman speed. So that's exactly what she did. Her legs became a near blur, her still-warm love juices matting the fur of her thighs acting like a vicious lubricant every time her thick leg's inner thighs grazed each other.

She would catch up with the peloton soon. At her current speed, she was on pace to set a world record. Remembering her body's current state she slowed. She couldn't finish like this. Everybody would see her, what a monster she was. Imagining the disappointed eyes of her girlfriend she groaned. Her girlfriend. She had promised her to never change again. There wasn't time to change back, even if she could she couldn't materialize new cycling clothes. She would know what happened. There wasn't a lie good enough in the world to describe the state of herself and her bike. Looking down at her bottomless voluptuously proportioned body she grimaced. Her pussy was still engorged and throbbing, the fur around it soaked through. Embarrassment and heat mixed in her gut. She wasn't strong enough to lose her. The walls she had built around the ache, the need were starting to crumble.

"I'm a monster...a monster," she sobbed, tears wincing from the corners of her eyes. There was no point in continuing, she had lost. She had lost everything. The bike slowed from its breakneck momentum. The heat took advantage of her weakness. There was no point fighting it. Maybe she was just a horny beast trying to be human. It was always there, she knew that, lurking under her skin. Fresh wetness was beginning to flood into her passage once again. This was all she was, all she deserved. She wanted to cry.

A pain lanced through her head so severe it forced her eyes to close for a moment. Quickly reopening them in an attempt not to crash she couldn't understand what would have caused it. Maybe it was... Maybe... Growing excited at the prospect she felt the wetness between her legs grow worse. Maybe she was changing back! She was on a bike, after all, she could go somewhere to get clothes, maybe skin her knee, give an excuse for the change. Contingencies and ideas on how to salvage the situation raced through her mind. The pain lanced through her head again. Something was wrong. This isn't how it felt when it receded. It was her horns. Something was happening to her horns.

"What's...happennngggg," she moaned. The cracking noise reverberated through her skull. She knew immediately that sound, it was how her changes always started but never this late. Her horns were growing! They never grew longer. The throbbing heat in her pussy flared massively, the strong muscles clenching between her legs. Sinewy strands of muscle in her legs tensed below her. Pleasure began to lance through her nethers. Immense pressure was building again behind her sports bra, the small domes of flesh pressing outward again.

"No...please...I can't take anymore, I can't," she tried to bargain with her own body. It refused to listen. The heat was getting worse, filling her mind with need. Feeling the ridged horns growing out of her head, thickening the weight of them was trying to tilt her head backward. The horns twisted as they grew above her, further spreading and cracking the vents in her helmet. Her breasts had started to develop cleavage, pressing into the sports bra with a heated insistence. They were swelling larger with every beat of her rapidly thrumming heart. Fatty tissue piling on the constrained mammaries. Unable to breathe she gasped for air. The tightness was impossible to put up with. Prying at the collar of the bra she tried her best to tug the taught garment down but it was impossible. Pulling at the bottom with her one free hand there was no way it was going to be folded up enough to make any difference.

"Oh fuck...oh fuuuuckkk..." she moaned, barely able to suppress a miniature orgasm from taking hold of her. Her body was out of control. But she didn't have time to think about that now. Getting the sports bra off was her highest priority. Reaching for her top-tube bag where she stored a few small gels and snacks. Throwing the snacks out with an urgent panic she rooted for anything to help. Her breasts were spilling out in every direction from the bra. Thoughts of impaling herself on the seat again were made real, her body acting on its own, angling itself to grind her swollen lower lips against the sticky seat. Finding what she was looking for she grasped her multitool. Unlike the rest of her kit, it was an old corroded thing, made of steel, handed down to her by her father when she showed an interest in cycling as a teenager. And it had a small knife. She remembered it distinctly, asking her father what she would need a knife for when cycling, he answered her that it was "better to have it and not need it than to need it and not have it". Now she was more than thankful for its inclusion.

Flipping through the hex keys with one hand was near impossible. Bringing it up to her muzzle she used her teeth to hold one end of the tool while her uncooperative fingers fumbled for the small blade nested at the far end after the flat head screwdriver. A shock of pleasure coursed through her body, her hand released for a moment, unable to maintain its grip. Dropping the tool she managed to catch it mid-air, her heart beating fast she could feel the heat threatening to make her cum again. Everything felt tight and hot. Her breasts were still growing, larger and larger by the moment. The fabric of the bra held tight despite it giving her a substantial amount of cleavage, pulling the straps into her furry back. The seat tip was inside of her again, her body unable to resist the sensation of something, anything, spreading her. With a herculean effort, she got the blade of the tool out.

With such urgency that she had no consideration for her own flesh, she stabbed between her breasts, piercing the stretchy immensely tight fabric, hitting the narrow air gap that had formed between them. Pulling upward the bra began to give way, tearing and bunching around the not especially sharp knife. Sawing madly the tip of the blade came precariously close to her sternum with every drag across the structure of the bra.

"Hnnghhh!!! Come on....uhnnn...come...on..." she moaned. Hot pulsing blood filled her cheeks, it felt like her whole body was pulsing. The fabric was shredding all over her chest but the bra held on. Shaking, her hand put more of her considerable strength into the sawing. She was almost there, just a few centimeters to go. Unable to breathe she worried that she may pass out atop the bike. With a *riipppp* the weight of her growing breasts finished her work, cleaving the garment in two.

Bobbing in front of her were two pert breasts, coated with white fur, each easily a handful. Her normally sized pink nipples topped the jiggling mounds. Sighing in relief she was able to gasp a full rich lung-full of sweet oxygen, even if the air was nearly as hot as fire between her legs. The skin around her breasts raced to catch up with their still-swelling size. Even relieved of the bra, she still felt great pressure behind her nipples. That wasn't right. They never got larger than this. They were as large as any reasonable woman would want. Crying out she bucked on the seat, the shudders of pleasure through her loins were getting worse again. It felt so good. She wasn't strong enough to fight it anymore.

"Muhhh tittssss..." she slurred through the slabs of her teeth. Her breasts plumped before her eyes, growing increasingly heavy on her chest. The larger they became the more of the wind caught them. The pressure was relentless, fatty tissue stacked on fatty tissue. The soft short fur on her boobs was thinning with their expansion before filling in again. Soon her growing jugs had grown as large as her head. The sides of the expansive mammaries pressed into the upper parts of her arms. Clit throbbing like a freight train her pussy clenched. She wanted to cum so badly.

"Uhnnn puh...please..." The pressure was so great in her chest she thought she may explode. Her tits bounced while they grew fatter and unnaturally buoyant. New nerves flared along their length. Her body, once boyish and thin, was now something beyond a wet dream for most men. A body was made for sex and sex alone. It wasn't only her body, the thought of it filled her mind. Her thoughts were overcome with ravenous hunger. She had never taken a male... a man. She wasn't wired that way, but she kept a small rarely used dildo in her bedside table. The ache was so intense it hurt. Needing something, anything in her she frantically looked around the bike. Below her top tube there it was. The water bottle. Still half-filled with sports drink, the diameter a fair bit larger than a coke can. No male...mate...was a match for its girth. But it was all she had left beside the unfulfilling and abused nose of her bike seat. Plucking it ravenously from its cage she brought it quickly to her lower lips, in her rush she neglected to turn its tapered end sporting the spigot towards her.

By pure happenstance, the bottle braced itself in the anatomic cutout of the seat, its spigot jammed in the tapered hole that the manufacturer had put in to relieve pressure for long rides. Now it served as the perfect leverage, giving her body something to push against. The bottle was all the liquid she normally carried on rides so she made sure to pack the longest bottle that would fit in her bike's bottle cage, an extra-large.

"HUUHNNN...UHNNN!!!" She moaned, her swollen lips pressing hard against the plastic base of the blue-green sports bottle. Breasts the size of small gourds they kept swelling between her arms. The erotic feeling of the jiggling flesh sent fresh shocks of wetness to coat the bottle below her. The maneuver she was engaged in with her hips forced her to stop pedaling. Gliding down the road her rear hub screamed, she was still going faster than most people could pedal at their maximum effort. Using her body's weight she pressed on the bottle. The rational part of her told her there was no way it was going to fit. The animal in her said otherwise.

Just as she got the first few centimeters of the bottle inside of her gaping, but somehow still excruciatingly tight pussy her breasts surged outward, growing the size of overripe cantaloupes. The furless expanse of her areola swelling so large that no reasonable bra could fully hide them. Eyes rolling in her head, her areolas distended and engorged below her pencil-eraser-sized nipples. Her still changing body would not let such small inconsequential nubs remain atop the twin peaks of her beyond ample bosom. Twisting and swelling the changes spread to her teats, the pink nubs protruding outward while thickening beyond the circumference of her fingers. Their flesh pinching and further inflaming as they turned the same shade of black as her puffy areola The pinching pleasure emanating from her new swollen breasts was indescribable. Arms shaking she thrust her chest outward, letting the wind buffet the sensitive nerves. Her pussy clenched, unintentionally forcing the bottle out of her entrance.

"EEIIIHHHHNNN!!!" She whined with a guttural lusty moan full of frustration. Toned stomach sucking in. The breath knocked from her lungs. Her love canal was strengthening, widening, burrowing even deeper inside of her. The already engorged labia guarding her entrance swelled between her thighs, flattening themselves against the blunt end of the sports bottle wedged against the seat. The furry expanse of her mound pressed noticeably into her thighs. Whole-body shaking, her entrance slavering juices over the bottle.

Choking out an animalistic moaning from her muzzle the excruciatingly sensitive nerves of her clit lit up all at once, the fleshy throbbing nub swelling swell so large that it stretched its fleshy hood. Her inner walls clamped together over and over. Massive tits bouncing wildly on her chest, their soft flesh buffeted by the torn sports bra and the unzipped jersey which they had far outgrown. Reveling in the weight of her heavy breasts her large rock-hard nipples throbbed with electric energy. Her body driving her insane. Hands twisting against the bar tape she began to tear the thin cork covering, revealing the taped cables and aluminum of her curved handlebars. She wanted so desperately to pull them away and grip her teats and dive between her legs. It was taking all her willpower to not touch herself and avoid crashing at whatever insane speed she was currently traveling.

The third orgasm of the ride hit her like a bus. Muzzle spreading and tilting upward her eyes rolled in her head. Her horns felt so heavy, so right. Bones in her face began crunching and extending longer. Breath temporarily caught in her chest the muscles in her chest and back tensed hard.

"UHNN...UHNN...UHNN!" She heaved. Every nerve was on fire. Mouth gaping a fresh gush of pussy juice sprayed from her nethers, bouncing off the bottle to create a massively wide fan of steaming-hot spray in front of her. The fluid splashed her arms and the underside of her breasts. The feeling of the fluid leaving her pussy only increased the white-out pleasure pulsing through her body. Every thought was pushed out of her mind except for the ecstasy. Breasts pulsing her inner walls undulated, milking the vast emptiness inside of her.

"HUUUAHHH!!!" She screamed at the top of her lungs, lurching forward. A second spray of juices followed the first, much less powerful and voluminous but just as deliriously rapturous. The smell and wetness of her sex were everywhere. Blind animalistic desire ruled her actions. Instinctively grinding her hips, riding out the climax the bottle pressed on her flaring lower lips. The weight of her wide hips pressed incessantly against it. Without understanding, her mind was so clouded by euphoria the fluid-soaked bottle was inside her again. Squealing at the sensation her pussy squirted again, clamping and holding the bottle inside of her. The girth of the sport-drink conveyer was spreading her wider than she had ever been spread. Greedily accepting the foreign object she needed more of it inside of her. Immediately. Oversensitive nerves that laced her entrance were lit ablaze by the object's merest touch. Hissing through her teeth the feeling threatened to send her toppling head over heels on the bike. Only the deeply ingrained instincts she had cultivated from years of training kept her upright.

Inches of the bottle sank between her legs, what she hadn't yet pushed inside dripped with her pungent juices, the plastic pressing into her tensing thighs. Her pussy went insane, the intrusion everything it so desperately wanted. Drool leaked from the corners of her mouth, powerful puffs of air snorting through her wide animalistic nose. Whole-body humping the bottle she shoved more and more of the extra-large bottle inside of her. Its circumference much thicker than any human could ever hope to be. The plastic along with its contents hot from being in the sun all day, along with the sport-drink mixture sloshing inside it all added up to giving her an analog to a thrusting lover every time she ground her body against it. It was a weak analog but she didn't care. It didn't matter if it wasn't entirely right, she needed it. The primitive and needful pounding at the back of her head told her the ache in the pit of her abdomen wouldn't go away without being penetrated. Even after three mind-shattering orgasms, the ache was worse than ever. She needed something inside to massage the throbbing gnawing need away.

Head lowered down she settled into a regular thrusting cadence. Her legs began spinning again, energized by her body's bouncing on the bottle. Breasts swaying heavily between her arms she was on the tail of the peloton now. Cutting through the air her bike's finely-honed wind tunnel aerodynamics were invalidated by her voluptuous form atop it. Screeching under her, chain whirring, she propelled the bike forward through sheer power. The pleasure between her thighs drove her to go faster and faster. Standing on the pedals in a powerful sprint she slammed her hips down shoving another couple inches of the bottle inside of her, a gush of fluid pressing out from around its circumference. Her vagina suckled greedily on the bottle, powerful muscles gripping and prying at the unresponsive plastic.

She was so close to the group of riders ahead of her she could smell their sweat, the deodorant they used, the acrid chammy butter they used to reduce friction in their bibs, and even which women were on their cycle. The sharp clicking sounds of their gears shifting in pretreating for a steel upcoming hill reverberated through her long ears. Grunting in pleasure, pronounced clit throbbing with her heartbeat she pushed harder. Her bike zipped behind the slowing group as they began the grind up the grade. Quickly gauging the terrain she knew it was at least fifteen percent. Purposely hanging back she followed them up the hill, applying the brakes. She could see the back of the other riders' calves bulging, legs straining. The slim bodies of the women in the peloton bounced on their pedals as they pushed against their bikes. Her own legs were barely trying at a cadence that felt more akin to walking compared to the sprint she had just engaged in.

The rider's trim toned physiques reminded her of how much she had changed, her own body now intended for breeding not cycling, excelled at it just the same. She had never changed so much before, her breasts were never so large nor her pussy so cavernous and gushing. The ache never so sharp. Unable to see them she was sure her curled ridged horns were a good bit larger as well by how much they weighed on her head. But there was no time for that now. Her heartbeat fast in her chest while she slowly, purposely gained on them. They hadn't even noticed she was trailing them, less than fifty feet away. Using every chance she got slowly following the other participants she pushed her body against the bottle, trying to sink more of it inside of herself, it was becoming a struggle. The hill had changed the angle of her hips to the bike, along with her own slick wetness she had lost some ground, the container slipping a few inches back out of her entrance. Breasts bouncing akimbo she moaned in frustration, unable to get the bottle back into her until they had cleared the hill. It took all her willpower to not race ahead of the slow riders.

The snake or riders crested the hill. Sitting down on their seats they zipped down the other side. She could see some riders at the back putting their all into staying with the group. If they left the cleft in the wind the group created they could get dropped and never catch up. She knew she had no need for the draft the peloton created, the strength in her legs felt limitless. The group of cyclists began pressing harder than usual. Looking at her fur-flanked tight sports watch she realized they only had a few miles left to the finish. It was time. She had to pass them.

Creaking below her, the pedals churned with all the power she had in her legs. Her bike accelerated sharply, coming alongside the group of riders. Their heads down, tracing the tire in front of them to avoid crashing. Coming alongside them she became intensely self-conscious. She was more or less naked save for the cracked helmet and the unzipped jersey that only accentuated her jutting mammaries. Her entire chest was varying levels of soaked with her sweet juices. Pressing her legs together she tried to hide her gaping pussy with half a water bottle protruding from her swollen lips. The ache only grew worse.

"Uhnnn....Fuuuuckkkk....." She moaned without meaning to, drawing attention to her. Several cyclists glanced towards her, their heads barely turning trying to maintain their position among the pack. Mouth agape a woman in a red jersey stopped pedaling, her bike slowing rapidly, the rider behind her narrowly missing her bike as she swerved around. Their eyes on her only made her body tense and throb more intensely. More looked at her, taking in her huge exposed breasts. The swell of her protruding nipples tingled and pressed outward with an unwelcome renewed pressure. Her tits were filled with pulsing energy and growing heaviness. Her teats begged to be handled, to be touched. The shocked scrutiny of the few riders that had noticed her only made the tingling in her knockers worse.

She tried to muffle another whine of pleasure, but was unsuccessful, the gurgle leaking out from between clenched teeth. The muscles of her pussy were filled with nervous excitement built out of the awkwardness of the situation. Pressure growing inside her breasts she couldn't help but resume her gyrations on the bottle while still weakly attempting to shield her privates from the passing riders with her legs. Fresh slick wetness gushed from her nethers. Somehow her body coaxed enough of the bottle inside of her that her lips grasped around the inset divot in the circumference that made it easier to latch into the bottle cage on her bike. Knowing her bottle well, she realized she was a good three-fourths the way down its length now. It was so big. So. Big.

"FUCK so full! So fuuuULLLL!!!" She whined, her voice lowering in a mix of fierce desire and frustration. The feelings were building in equal measure. Her inability to relieve the pressure in her cunt and boobs drove her wild. Inner walls gripping the bottle mercilessly her breasts swelled atop her chest. They couldn't get bigger, could they? But they were. Drops of clear liquid coalesced on the tips of her nipples. Eyes bugging out of her head her embarrassment at the scene she was making was immeasurable as the heat whipped through her frame. The jiggling weight of her swelling tits pressed past her locked elbows while their furry flesh stretched excruciatingly tight.

"What's hap...hap.,.happenuuhnnnn!" Groaning, gasping for air, her breasts pressing together between her arms like immense fleshy balloons. It felt like the ruined sports bra was constraining her chest again. More of the clear liquid began to leak from her jutting teats. Trying to pedal faster, to get away from the group she couldn't make her legs work properly. Thoughts of taking her girlfriend's muff lowering onto her face, the sweet juices of her pussy washing over her face filled her mind. Trying her best to push the lewd thoughts away her own eyes were fixated on the rise of her breast. It was taking everything she had not to pinch and pull their erogenous flesh like massaging out a muscle spasm. It would only take one hand... But no, she could barely keep the bike straight as it was. Her grip on the handlebar tightened, fingers scratching the black coating of the aluminum leaving silver gouges in the metal. The clear liquid began to grow more opaque with every drop. Hissing through her teeth in pleasure she realized the fluid was turning white, the beads pearlescent in the afternoon sun.

"Mi...milk? No...it's not posi-" her words cut short by a spasm in her vagina that coordinated with an increase in the volume of the sweet mixture issuing from her nipples. Mouth gaping, throbbing pressure made it impossible to coordinate her body. Bucking wildly atop the bike she didn't know how but she could feel ducting swelling in the expansive fatty tissue of her tits. Her already-hard nipples grew even more concrete-like, engorging with the drumbeat of her scalding blood. Their flesh shuddering, tingling, twisting in the air, their girth thickening atop the swell of her areolas. Creeping in among the shocks of pleasure and discomfort that wracked her physique was a feeling...like...like she needed to pee very badly from her nipples.

Moaning in frustration unsure what to do, her body took action with the only thing it could control. Thighs pressing inwards, furry knees touching the top-tube of her bike, her hips ground needfully, urgently against the bottle sunk inside of her. Shifting the bottle's position made the pressure between her legs feel more manageable. She still needed it deeper inside of her, badly.

Clearing the divot her pussy stretched once again, taking the full circumference of the top of the bottle. More wetness oozed from her stretched lips. She had a good ten inches of the approximately fourteen-inch long bottle inside of her. The blunt end pushed into her, stretching her already expansive pussy to its limit. Clit angrily pulsing above the intrusive object she could only pound the bottle end against the seat like a jackhammer, fighting for every new centimeter.

Chest thrusting outward she couldn't do anything to stop the increasing flow of milk. The sensation of the liquid pressing out of her tits, aided only by gravity and her terrible horniness made her only feel hotter and hornier. Riders were speaking now, somebody yelled. Despite the acute hearing, her long ears afforded her she couldn't make out the voices above the din of her own heart pushing the need through her veins.

"Uuuhnnnn!!! So FUULLLL!" She moaned unable to take the inability to touch her swollen breasts a moment longer. Her body was so tight it felt like it may explode. She had to do something. An idea pushed through the cloud of lust that fogged her mind. Leaning forward, lifting her body off the seat, she went into her most aerodynamic position. Her large hands gripping the drops of the abused handlebars, forearms flattening parallel towards the ground. Bountiful ass cheeks sticking into the air, her tail waved like a flag behind her. Head leaning over the bars, her wet throbbing nipples touched the flattened top of her handlebars. A bolt of electric pleasure shocked her body, pussy spasming at the sensation. Moaning, she let more of her weight rest on her breasts, their bouncing expanse dragging the sensitive nubs across the torn bar-tape. The white sweet-smelling liquid flowed with an increasing volume, quickly coating the top of the handlebars with the thick substance. The fur coating her mammaries was saturated from the nipple down. In addition to her own sex, she could smell how sweet her own milk was. It was only adding to the ache that felt nearly unquenchable. Even in her tucked aero position, she could feel the milk pushed along her stomach by the wind to join the liquids continuing to assist in the ongoing effort between her legs. Every shudder and jiggle her harsh bike frame transferred from the tarmac underneath her tires pressed more milk from her breasts, but it wasn't enough.

She could feel through her pussy that the bottle's spigot was sporadically touching the tip of the saddle behind her. Every time it caught it made her gasp in pleasure, milk issuing from her teats. Eyes half-lidded in a daze of lust and need, she almost didn't have time to react to the cyclist tumbling end over end in front of her, their bike skidding down a grassy incline. Jamming on the brakes she didn't even need to think, all her training had honed her reflexes to a razor's edge. Disc brakes squealing her bike narrowly dodged hitting the crashed cyclist. The sexual cloud that hung over her mind was lifted temporarily by pure adrenaline. The rapid deceleration had pushed her buxom body forward, almost off the bike. When her legs resumed her acceleration it pushed her backward with almost as much force.

The bottle's top few inches that had been dangling from her pussy like a half-inserted dildo caught on the cutout of the seat as she accelerated. Her entire body's weight was pushed onto it, jamming the entire bottle into her gaping cunt, only the spigot managed to push past her thick lower lips. Head rearing to the sky, she saw god. Lightning crackled through her spine, vision going white. The bottle touched the ache for the very first time. She couldn't hear, she couldn't see. Every nerve in her body fired at once. Fireworks exploded in her head.

"UUHHNN AAAAARRRRRRHHHHH!!!" She roared to the sky, her entire body clenching like a fist. Hands letting go of her handlebars they latched onto her immense breasts. Her frame sitting upright on the saddle, back arching she came harder than she had ever before. Spasming powerfully the walls of her pussy hammered the fully-submerged bottle, a spray of fluids forcing itself out of her like a water cannon, soaking the already drenched bike beneath her. As soon as the first blast had finished she squirted again. And again.

Dynamic powerful muscles tensed and released beneath her skin. Milk shot in twin streams from her tits, the white fluid arcing in the air, coating her chest and face as it was caught by the wind. It was like she was cumming from her breasts as much as her pussy. Unable to stop screaming in indescribable pleasure she bucked like a wild animal atop the bike. Madly squeezing her nipples with her hands she shot stream after stream of the thick liquid into the air, the pressure of the fluid causing miniature eruptions from her teats between needful pulls. The bottle sloshed inside of her, the muscles in her pussy desperately milking the ungiving plastic. Thighs squeezing together the container's spigot popped out, unable to take the pressure any longer. Sports drink squirted out from between her legs as she came again from the sensation.

The structure of the bottle collapsed inside of her without the liquid to push back against the powerful muscles that grappled at its structure. Hips bouncing madly atop the seat she felt the massive girth of the container collapse to a fraction of its size, the smooth surface imploding under the assault of her orgasm. With a *pop* the top of the bottle came completely off, the underlying bottle too contorted for the threads to hold. A few last sloshes of the sports drink leaked out between her lips before her pussy unwillingly released the crushed bottle. Its immense circumference reduced to something akin to a churro made of green-blue plastic. The powerful muscles of her vagina were unable to hold onto such a thin twisted twig between orgasmic spasms.

The orgasm seemed to last forever. Her body convulsed with the aftershocks. Fur thoroughly soaked with her own juices she began to come back to reality. The ache was diminished, but not gone. Wincing at the fresh emptiness between her legs, she could feel the hot air filling her gaping love channel. Muscles beneath

Somehow, if by a miracle she was still upright and moving forward on her bike. It was only then she began to take in the surroundings. There was yelling behind her, glancing backward there was a massive pile-up of cyclists and bikes. Grimacing at the scene couldn't linger on it or even fully process it, she had to get back control of her bike. She was surrounded by balloons, flags, and metal fences that contained a throng of onlookers. It was the finish line.

Grabbing the brakes hard on her bike she skidded sideways to a complete stop. Her labia flicked across the top tube of her bike in the process, making more milk gurgle from her nipples. A fresh splash of wetness smeared its way across the top tube trailing her pussy. Doubling over in pleasure she could feel herself almost cum again, every erogenous zone was dialed to eleven. Hearing a crunching noise beneath her she looked down. Her enormously expensive cycling shoes had just broken underneath her hooves, the carbon cracking in half, leaving her feet to rest on the hot pavement. It was then she noticed that the white line signaling the race's end was behind her rear tire. She didn't know what place she had come in, it hardly mattered to her now. Huffing for air, still shaking from her multiple climaxes she looked behind her. The peloton was a wreck, a few stragglers weakly approached the finish line, before coming to a stop thirty or forty feet from the line. Despite the obvious exertion, their faces were near-white. Looking down at her body, her hands, her tits... she realized fully what she had just done.

"Katie! Katie! Over here! KATIE!" A voice called out from the crowd.

Somebody was pushing their way through the swell, she couldn't smell them, there were too many people. But she knew that voice anywhere.

"Katie! Oh god....What did you do?" Amanda said as she made her way to the front of the crowd, her lanky body pushing against a metal barrier. Eyes a combination of concern and horror. The red locks of her hair frazzled, falling in front of her face.

"Oh...oh god..." Amanda gasped, her eyes widening, taking in her figure.

"I...I can explain..." she stuttered as an aftershock made her grasp the bike for support. Hooves clacking against the pavement only accentuated their monstrous nature. Despite all her efforts, the ache was still there, pounding at her head and in her pussy. Looking up she saw that the crowd around her was dead silent, their eyes transfixed on her. Hands gripping the banister of the barrier, her girlfriend was the only animated figure.

"Doesn't matter, meet me at the car, it's in the field by the buses! Hurry!" Amanda said in a panicked tone, her body visibly shaking. Amanda's knuckles were turning white.

"Hurry!" She said again to emphasize the urgency before she disappeared back into the crowd, the throng of motionless people, most of their mouths agape, swallowing her lithe form.

Taking a deep breath she looked around herself, it was as if the world had gone silent.

"Ok. OK," she said to herself, trying to get herself under control. She could make it. She had to. Amanda's eyes haunted her. There was a girl's scream from the crowd, somebody finding their voice. And then all at once, chaos erupted. People were scrambling over each other. Some flipped over the fences towards her while most were tripping and flailing to get away. She had to go now. Adrenaline pumping she shouldered her bike and ran towards the parking lot. Breasts swaying and bouncing she bounded through the crowd. A chain-link security barrier blocked the finish line from the outside world, the white check-in tents shook with the throng of people barreling through them.

Muscles tensing in her legs she ran at full speed towards the fence. It didn't matter that she could feel her mound between her legs or that her tits were still throbbing, laden with what she was sure was much more of the sweet liquid. All that mattered was escape. Rapidly approaching the fence she pushed down towards the earth with all her power. Launching into the air she easily cleared the fence, the g-forces of her own jump making her feel motion-sick mid-air. Landing in the long but car-tire trampled grass her hooves found purchase in the soft soil. The bike caught at the last minute from impacting and destroying her expensive carbon wheels. Breasts bouncing against her arms she ran towards the part of the field that was the team staging area.

Scanning the area near the busses she felt a panicked dread. Amanda wasn't there. Running circles around the grand tour-busses that sported the team's logos she couldn't find her anywhere. A sudden honking made her ears flicker towards the entrance. Sprinting past the busses she spotted Amanda's small silver sedan at the entrance, ready to make a getaway. Leaning out of the driver's seat Amanda waved frantically at her. Waving back she ran towards the car, her hooves digging muddy trenches in the grassy field.

Reaching the car they looked at each other briefly, the look in Amanda's eyes said everything to her. She knew what she needed to do. Lifting her bike onto the rack suspended from the trunk of the car she tried to secure it but her thicker hands couldn't quite work the rubber straps properly. Seeing her frustration Amanda pushed her aside and cinched the bike that cost more than her car to the rack suspended from the trunk. The touch of her hand on the fur of her arm sent unintentional shivers down her body. The ache growing worse.

"Get in! Sunroof's down!" Amanda barked tersely, sounding entirely unlike herself.

Trying to maneuver her way in was an unforeseen challenge. Having no idea how long her antlers had become she tried and failed to get her head into the small car. She could hear the tips of the pointy protrusions puncturing and tearing the headboard liner. Moaning in frustration, tears began to form in the corners of her eyes.

"To the left, down...down...ok turn right," Amanda, seeing her frustration, guided her. Grimacing at the sound and feeling of her antlers ripping two long lateral tears in the car's upholstery her head finally cleared the obstacle. The sides of her antlers banged into the trim of the sunroof like a plinko token as she tried to maneuver the rest of her body into the seat. Her normal seating position was far too forward and too high. Barely able to fit her digitigrade legs into the footwell and still wriggling in the seat, trying to adjust her tail she managed to get enough of her inside to close the door.

"Go! Go!" She urged Amanda, the door slamming shut, she could tell that she didn't have to tell her twice as the car accelerated out of the field like a bat out of hell. The tires dug small trenches into the wet soil before careening them onto the country road that led to the race venue. Finding a position that was comfortable enough she took a deep breath. Amanda was facing forward, jaw clenched.

"Hey...I...don't know what to say..." she said after sitting in silence for a few minutes, only the noise of the sedan's economical engine and the tires against the pavement filling the void.

"Do you realize what you did? I..I can't believe you would do something so...so..."

"Stupid?" She offered, sheepishly.

Amanda nodded.

They sat there in silence again for miles. The wind whooshed above them, buffeting her antlers. She could only look forward for fear of further destroying Amanda's car.

"You know... I have never seen...this side of you before," Amanda said so quietly it was almost a whisper.

She looked at her girlfriend confused. She had shown her this side of her on their fifth date. That was more than two years ago.

"What do you mean? You knew-"

"Not like this, you are...you look..." Amanda cut her off. "Really hot," she said, cracking a faint smile. "Since when did you have tits? And milky ones at that?" She asked, her tone softening.

"I...don't know, I just got so hot and they got so big. It's never happened before, I swear" she admitted while hefting their soft flesh in her hands. Milk began to leak from her nipples at the touch, a shudder of pleasure coursing through her body making her clit pulse. They were immense, feeling bigger in her grasp than they even looked on her chest. Legs squeezing together she could barely stifle a small moan. Unable to remove her hands from her chest she felt herself grow wet again, the hot slick fluid leaking onto the leather car seat below.

"Are they really that sensitive?" Amanda asked, her body language relaxing. She could only not, her teeth gnashing against each other trying to hold back the heat. Hands pressing into the soft fatty flesh of her melon-sized breasts she gasped at the pleasure they could elicit.

"Hey, watch my seats!" Amanda said sniffing the air, her eyes going wide before giving her a knowing glance.

"I'm s...sorry I can't help it," she could only moan lustily, her hands beginning to knead her breasts, extracting gurgles of milk from their swollen nipples.

"I should be the one getting you wet," her girlfriend said mischievously, her face turning to hungrily look at her body. One of Amanda's delicate hands detached from the steering wheel and landed on the broad flesh of her inner thigh.

Shuddering at the touch she could only moan, her legs instinctively spreading for her girlfriend...her mate.

"Oh wow...oh wow..." was all Amanda could utter, glancing at her engorged dripping pussy and back at the road several times.

"Puh...please...inside me," she whimpered, needing to feel her girlfriend's touch. Her arms full of her leaking bosom which was starting to speckle the inside of the windshield with small droplets of white sweet milk. Amanda's hand slid downwards towards the oven between her legs. Her svelte hand explored the firm flesh of her pussy's lips. Amanda's digits were almost immediately soaking wet.

"Oh god, Katie...what are you doing to me..." Amanda moaned, her voice growing lower and needier. Her long ears could hear the bones in her face rearranging and stretching before she saw the muzzle begin to stretch the skin of Amanda's face. Thick whiskers sprouted quickly from her developing muzzle. Lips parting, immense feline fangs stretched her gums wide. Letting out a plaintive growl she shifted in the driver's seat. Even as she changed, her spasming hand managed to immerse itself in her pussy, squelching the slick juices soaking her cunt audibly. The feeling of her girlfriend's fingers crunching and cracking inside of her, growing larger and more vicious was indescribable. The prickle of blooming claws on Amanda's hand was all it took to make her cum again.

"I can't hold it...I can't..." she shuddered before screaming in rapture. Sucking on her girlfriend's growing paw, her pussy clamped down hard on the changing digits. Milk sprayed the passenger windshield, aided by her own vice-like grasp on her nipples. Bucking and grinding in the chair she felt like the orgasms would never stop. She never wanted them to.

"Grrrrghhh...Should have waited till we got home, but this will have to do," Amanda growled, her face extending further outward as she steered the car onto a gravel shoulder. Moments after she put the car in park, her simple blue blouse began ripping and shredding around growing muscles and bulk. Even in her own rapture, she could see that Amanda's cleavage was deepening, pressing against the cups of her bra. Golden yellow fur raced to coat her girlfriend's growing face. Wincing closed Amanda's eyes reopened to reveal piercing lusty yellow feline eyes.

"Let this kitty put those milkers to good use..." Amanda growled, ears migrating to the top of her head. Taking one of her heavy teats into her mouth she began lapping it with a huge sandpaper-rough tongue. "It's time I congratulated you properly for your win today," Amanda purred looking up at her, their muzzles intertwining. It was only right that her girlfriend gave her the first taste of her own milk.
