Part 4 - Mates

Claire was overwhelmed, lost in her own lust. After she failed to find the release her body so desperately needed with James her thoughts had become disconnected, scattered. Her nervous system was overwhelmed by her bodies enflamed, throbbing desire. Only her most carnal heat-driven urges pushed through the fog.

Claire was an increasingly faint whisper in her own head. She was drowning in an ocean, the incredibly horny leaking wolf dragged her deeper and deeper into its depths. She growled and moaned from a place deep within in her heavy chest. Her body was driven to mate, but with no suitors available to meet her needs her hands could only do so much. They delved deep into the thrumming depths between her legs. But the claws that adorned her hands made them poor masturbatory tools as she yipped in frustration as the sharp points touched her sensitive inner lips. Her body tried desperately to find a satisfaction it could not achieve alone as she rubbed and pushed a thick padded paw across her wet sex. The fires deep in her enflamed nethers smoldered unrelentingly.

Her body laid prone at the foot of her bed. The soft rays of moonlight filtered through the cum-splattered glass across her voluptuous powerful curve as brought them into sharp relief. Her mountainous bosom rose and fell with her steady sporadically hitched breaths. Large dark, still-erect, nipples leaked the smallest beads of creamy milk onto her broad areola before the white droplets made their way into her soft-furred cleavage. Her chest was already a forest of fluid-matted fur.

Claire's thick hands were too occupied slowly massaged and plyed at her wet pussies folds to pay attention to her achingly full breasts. The wolf wanted relief the pressure, the heat. It had already tried to offer its overly full breasts to the weak human. His small mouth didn't even try to coax the milk from her teat. She had to force him. The relief was only temporary, it only served to make the persistent pressure in her tits worse as they stretched impossibly fuller. She writhed on the floor as she yowled softly. She leaked as the pressure built and built. As a few more sweet droplets pushed through her tight breasts' ducts her thick pussy temporarily intensified its leakage before ebbing again.

In her sex-addled stupor her erogenous zones had grown massively expansive. Any touch of her thickened wolf skin by her paws sent a electric shock into her still weakly leaking pussy, making her breathing catch and her nostrils flare. It stoked the heat inside, but it was frustratingly short lived. Claire growled in unmet need between huffing pants. Her wide flat tongue lolled out of her mouth. She almost climbed to the peak of orgasm only to have the heat die down back to an infuriating aching simmer again and again.

While she writhed James's nostrils flared as he took in the her musk. His massive lungs breathed the strong scent deeply as it filled his senses. The distinct flavor found its way onto his thick tongue as he tasted her strong sex pheromones. He could sense her heat, her fertility. Pre dripped out of the gulping urethra on the end of his quickly re-engorging penis. His tool jumped to attention between his legs, its soft length dragged over the fluid-stained floor.

His flow of pre sped up as he continued to breathe her in. His own musky lubricant cascaded down the ridges of his flaring head and long shaft, splatting onto the floor with increasing frequency and volume. He could feel his own pre-cum's slick liquid heat stream over his achingly full balls. His recent orgasm barely putting a dent into their churning reserves as their tremendous mass thrummed between his legs.

"Hhhnnnnhhh" he moaned as he separated himself from the abused wall with some effort. James staggered forward on unfamiliar digitigrade legs. His large chestnut-furred butt cheeks slapped together, their tight flesh jiggled slightly as they closed over his sensitive pucker. His balls dropped heavily in his tight sack as they smacked his thighs. Almost twenty inches of equine penis strained from between his thighs as it whipped a rope of steaming lubricant in front of him. His cock signaled the way as it paved a trail towards his prize.

Thick sinewy muscles moved under his furry skin as his large hooves clattered on the juice-soaked floor. His body managed his foreign and ungainly legs with an instinctual ease. His only priority was to make its way to the masturbating she-wolf as quickly as possible. His body lumbered as new but not unfamiliar to a strange new part of himself.

Claire's amber lust-glazed eyes were half closed, lost in the seemingly never-ending heat. All she could see through her heavily-lidded eyes was the moonlight on her throbbing tits, their twin rises obscured the large horse as he made his way towards her. Her breasts shuddered with milk as they swelled little by little, already the size of overripe melons, the liquid that sloshed inside stretched her dark bosom's skin even tighter. The mammaries quivered with every touch of her paws on her wet lower lips as they gaped open.

As her paws serviced the throbbing ache deep in her loins her strong sinewy arms pressed against the sides of engorged mammaries. This only served to further deepen her gently heaving cleavage. She twisted her muscled furry legs together, covering her wetness and delving paws with her voluptuous thighs. She pressed hard against her mound as her paws sunk ever deeper into herself, a constant stream of drool leaked from the sides of her muzzle as it groaned.

Thats how James found her. Claire's legs pushing her delving paws into her pussy, rolling back and forth slowly on the floor. A small steady trickle of her juices flowed out from between her twisted legs as she made low growls and moans. Claire was too close, riding the edge of orgasm, to notice his presence even as his throbbing shaft cast a long shadow over her writhing form. Drops of hot pre dripped onto her thighs, soaking into her fur. Her body shuddered involuntarily but was otherwise unresponsive to him. The wolves legs continued their slow twisting-grinding in sync with her moans. James's massive equine body shook with anticipation as his eyes sized her up. The flow of pre that leaked across the engorged head of his penis increased even further. The treasure trail soaked the underside of his jutting member down to his sheath. His body urged him on, urged him to mate.

He crouched down, his huge body loomed over her. His breaths were speeding up as he inhaled her even thicker scent. He was so close to the source now... James's large sac came to a rest on the floor, its contents rolling in its tight black skin. Hs rigid throbbing length hovered over her, hard as concrete, secreting his own potent musk. James's column strained, its immense length was barely enough to contain the powerful sex muscles just under the skin. He was just inches from her undulating canine legs. With thick-fingered hands he grabbed her padded feet, avoiding the vicious claws adorning each of her toes, and untangled her legs. His biceps bulged as he pulled her strong unwilling limbs apart.

Claire finally noticed. She bucked as her soaked paws withdrew slightly from her pussy, freed from under her grinding thighs. The cool night air licked her insides. Her hands attempted to dive in again, unable to be without something inside her for more than a moment. The heat simmered deep inside her, it threatened to go out and leave her need unfulfilled.

Slowly...slowly she became aware of the male that loomed over her, his imposing figure a blurry shadow in her lust-glazed eyes. She could barely see him over her overfull bosom as it rose with every breath. He was male, her senses could tell that, but didn't smell like her kind. She was beyond caring. He was male and his strong sex musk filled her nose and filtered into her strong lungs.

Should could tell, even across species, that he was virile and eager to mate. Part of the wolf told her to reject him, but the need was strong. "Grhnnn..." she growled defensively in warning, baring her teeth. Her paws protected her sex as her sex-juice drenched tail curled around her thighs to cover herself. As she rumbled her growl turned huskier and deeper. Her vocalizations quickly turned into a plaintive canine whine. The ache. She couldn't resist it. It was so deep inside, it burned her. Burned her with a fire that she couldn't put out. The wolf, subdued her ability to think and reason so completely, fought with her, but even their combined efforts were losing.

Hesitantly she spread her legs wider for him. Her submittal partially unwilling as her tail uncurled, revealing her sopping wet sex. She knew, at some level, that her hands and legs were a poor substitute for a real male's meat between her haunches. Even if that male smelled...off. Her female needs were just too strong. The males grip on her feet tightened but offered no resistance to her desire.

Her thick fingers prayed open her wet quivering mound as she thrust her hips into the air as best she could with her ankles gripped so tightly. She invited the male inside. Her overstimulated clit, as thick as a human pinkie, stood to throbbing attention atop the spreading wet folds of her pronounced leaking mons.

James's eyes widened and his mouth began to froth with excitement as he saw her soaked pussy spread for him. Her thick lips winking and spasming in anticipation her clawed hands pulling at her labia, trying desperately to keep herself open him. Her crimson inner walls pulsed with increased urgency as her pussy began to truly leak again in earnest. The trickle of slick juices that leaked out of the bottom of her gaping opening surged. A small stream of fluids splattering wetly onto the tail fur under her.

Large nostrils flared as James positioned his body. His hands pulling her legs even wider to allow him access to the furry engorged lips of her pussy. His straining shaft was made of steel as he was forced to release her right leg to guide himself downward to her shuddering hole. His hand pushed down on pulsing column with some effort as he maneuvered its head inline with her sopping passageway. It was made even more difficult by the copious amount of pre that had poured down his penis.

His length wet and slick and uncooperatively buoyant as he tried to steer it downward. He got in closer, his balls dragging across the floor as the slightly doming head of his cock was close enough that it skimmed the wolfs nether lips. Her labia sucking and grabbing at him as he struggled to position himself. James didn't have enough mental faculties at that moment to engage in foreplay. However the more he struggled with his cock the more he teased her. His cock's head dragged across her pussy, driving her into a needful frenzy as she struggled to thrust her hips to meet him. "Arrrwllllllll......rrrghhhhh" she grunted and moaned in frustration. Any hesitation was gone, she wanted to mate, wanted to mate with him so desperately.

James was straddled over her now, his massive frame supported by one heavily-muscled arm as the other was locked into a death grip around his medial ring. His heavy body shook with desire and anticipation as his too-long male-hood clumsily smacked into Claire's thighs and ass. What small amount of patience his desire to mate had maintained it just as quickly lost.

"WHINNNIEEE!!!" he bellowed loudly in frustration, his lips curling backward to reveal his broad teeth as he thrust more frantically. His cock blindly searched for her opening as it jammed against her. His nostrils flared, froth spewing from his mouth as his body was driven harder by the uncontrollable urge to mate, his balls lanced with urgency. Claire's hands were too occupied trying to keep her slavering labia parted to help as she yipped at the horse's clumsy thrusting.

Claire's breasts didn't help matters as their firm flesh was too large for her muzzle to properly see past. She could feel his enormous pre-drenched head prodding her as she tried to blindly reposition her hips to meet him, only to have James recalibrate to her previous position. Their sexual frustration built and built. Then, with one large thrust and a audible "squelch" of juices, he was suddenly in her. Both the horse and wolf's vision went white in agonizing pleasure as James's cock spread Claire. Their bodies were wracked with shudders as it overwhelmed their every sense.

James pushed his raging horse cock deep as he could into her wet grasping heat, sinking six inches of himself into the wolf. Their mouths gaped in unison as their eyes rolled backwards into their heads. Neither had ever felt something like this before. Muzzles opened and closed wordlessly, unable to form even an animalistic grunt or yowl. Their joining sent numbing electricity that overwhelmed their nervous systems, their bodies convulsed, joined at the crotch.

Even as their hips were finally joined the searing heat grew worse, it coursed through their bodies as James's one supporting arm gave way. The horse collapsed onto Claire. His substantial weight caused his broad muscled chest to slam against Claire's voluminous jutting breasts. Her swollen milk-leaking nipples pushed hard into his twitching pecs as they came muzzle to muzzle. They looked at each other lustily, needfully, both understanding what they could give each other. But there was no glint of recognition in their eyes. Their joining wiping away what little residue of their rational minds had managed to hang on through the onslaught. Predator and prey, carnivore and herbivore, the only things they shared were the ache, the heat, and that was enough. All that mattered was their union. They needed to mate, their eyes wild as they nipped and licked at each others faces and necks.

As he nipped her pointed ears James pushed himself deeper into Claire as his instincts took the wheel. His cock throbbed, demanding release, his balls roiling heavily between his thighs. With some effort he raised himself back up, off the wolf, making her moan as he further impaled her in one smooth motion. His hands, now free, dug into the soft wood floor as his arms supported his body above her.

"Hrrhnnnghh...whinnniieeeee..." he moaned through his long face as he began to pull out of her. She writhed, unable to take the absence of him. He pushed himself back in, deeper and further than ever. She responded with a plaintive yowl as she grabbed his elevated body for support. Her paws lifted her voluptuous form off the ground as she hugged the horse's broad torso.

James's hips began to powerfully gyrate, his massive spherical ass cheeks clenched, as he thrust into and out her. He moved slowly at first, his huge cock struggled to part her virginal love canal. He began to steadily speed up. Wave after wave of their combined juices gushed out of Clair's tight pussy opening with obscene wet splashes as his cock pushed against her strong inner muscles. Claire's labia clutched at him, unwilling to let go as her wet inner walls heaved and gripped his immense girth. Her strong vagina milked him for all he was worth. James could feel her body's resistance to his size and it only made him want to push deeper into her.

"Hurrr...hurrr....hurrrrr...nnngghhh!!!" James grunted as inches of his cock steadily disappeared into her with every heavy thrust. Her lupine pussy stretched wide for him, but he wasn't near done.

Claire thrust herself onto him in turn, her sexual plateau was at an end as she came alive underneath him. Her hands grabbed handfuls of the fur on his back as her claws raked across his thick skin. Using him as leverage she pushed herself onto his tool with ferocity.

"GRrrrghhHHHHHurrrrr" she moaned as he was stretched her with every thrust. She reveled in the fullness, it was an ecstasy the wolf had never known and she had to have more. The sensitive nerves in her pussy pushed her pleasure higher and higher as she leaked a river of steaming hot juices over invading column of stallion meat. Her clit raged as it dragged along the top of his slick throbbing length.

When he pushed himself back into her she felt so full, so complete. As she was taken by the horse her overfull tits leaked faint white rivers down her substantial breast flesh. She couldn't hold onto him much longer, the pleasure was too great, making her body shake uncontrollably. As she fell back onto the floor her black nipples strained upwards towards the horse, more engorged and strained than they ever had been. Every thrust caused her to yowl and moan uncontrollably as electricity arced from her clit to her heaving mammaries.

"Awrlllll....AWRRLLLLL!!!" She moaned as her milk ducts filled, the liquid caused her nipples to swell even larger. The twin nubs puckered slightly as their flow temporarily staunched. She thrust out her massive chest as her nipples erupted like a geyser, fueled by the immense roiling pressure in her breast flesh. Her paws, previously occupied massaging her mons around James's girthy horse dick, moved to her massive spurting jugs. Every heavy thrust of his dick stoked her milk flow, spraying the horse's chiseled chestnut-furred chest. The sheer fur of his tensed pecs quickly became saturated, the milk leaked back onto her own heaving body, drenching her mammaries' fur in turn.

Unbeknownst to Claire she had taken only just over half of James's length into herself. His throbbing medial ring madly thrust against her as it attempted to spread her still-spasming labia. James was undeterred, he thrust faster and faster, his long mane flew around his muzzle as he pushed himself into her with a heat-driven purpose.

The long scratches on James's back began to leak small rivulets of crimson blood as his increased exertions made every sinewy muscle in his body tense. And yet he pushed. He was too overwhelmed with instinct and pleasure to notice the pain. When he pulled himself partially out her pussy moved with him, only reluctantly letting go as air got between her inner walls and his tool, breaking the seal. A torrent of backed-up love juices flooded out from between them onto the floor. Every additional inch of himself got progressively harder and harder to push into her. James's instincts told him to hilt, he needed to breed.

"NnnnneeiighhH!!!" He huffed as the powerful muscles in his neck bulged under his skin. His lips curled backwards, revealing his flat teeth as the rush of powerful equine hormones that pumped from his throbbing, roiling balls lit his blood on fire. His eyes rolled in their sockets as the need increased. The horse needed to keep his mate under his control so she would bear him many foals. No rivals would challenge him. His instincts didn't account for a species mismatch and there wasn't enough of James left to say any different. So he pushed.

"Aaaaaaarrrrrrwwwllllll" Claire yowled as his medial ring pushed against her madly leaking nether lips. Drool was dripping out of the sides her muzzle as she panted hard, her wide tongue rolled out of her mouth. Her fingers dug into her mammaries as his medial ring rubbed against her over-worked hyper-sensitive clit. Streams of hot milk jetted out of her as she hugged herself. The horse's thick ring forced her open with a wet squelching *pop*.

Sixteen inches of James's length was inside of her now. Her pussy was beyond tight as its muscles did their best to coax the immovably hard flesh of his shaft. His weighty sac was close enough now that as it dragged across the floor with each thrust it gained enough speed to slap her ass. As his testes began to impact her voluptuous jiggling butt their virile contents heaved. James cried out in lust as they caused spittle to spray from his gasping mouth.

His flat still-leaking head flared as it finally pushed against her needful cervix. He still had almost four inches of thick horse cock between his legs that he could not get fully inside of her. His blind desire to hilt made him thrust so hard he dragged her heavy lupine body a few inches across the floor, his cock's head forcing its way into her ovulating and fertile uterus.

"Hurrrr....arrhhh...hurrr...nnnnghhhh..." was all Claire could grunt out as her immensely strong walls rippled up and down his length, her own substantial heat mixing with the horse, her pussy an inferno. They were getting close, Claire's ministrations sped up, her pussy madly milked his rigid length. James's balls hitched up towards his crotch as his head's ridges flared deep inside of her, stretching her insides even more as it did its best to seal the entrance to her cervix. Claire's breasts jiggled and leaked copious amounts of milk as she wrapped her legs around James's lower back, using their strength to raise her ass off of the ground. Her fingers gripped his back tightly as she pulled herself into him as hard as she could. Their thrusts quickening, becoming frantic as they edged closer to release. Their muzzles agape as they moaned, connected with each other.

Then it happened, James saw stars as he reared his head. Huge flat teeth gritted, muscles tensed in his arms. His thighs spread as his balls pulled up towards to his crotch. The thick black skin of his ball-sac shuddered as his testicles tightened against each other. A column of cum up pushed through his engorged urethral tract at an excruciatingly slow pace. He could feel the seed as it moved up his massive two foot length, causing his length to swell even further. Claire's tight walls gripped him hard.

"NEEEIIIIIGHHHHHHHHHH!!!!" he roared deeply as he erupted into Claire's fertile pussy. His head thrown back as foam flew from his mouth. His pecs convulsed as his arms and legs shuddered. His balls convulsed between his thighs as they visibly pumped below his throbbing taint. The pressure reached his cock's flared head as his over-engorged cock pushed rope after rope of his equine jism deep inside of her. All his senses went numb, he couldn't see or hear, everything became noise. All he knew was the ecstasy and need.

Claire felt him getting close, his balls pulling up to his deep-set crotch as she rubbed herself against him, her body shook in anticipation. Her breaths quickened as she felt him swell inside of her. "nnnnnnaaaaARRRRRHHHHHHHH!!!" she cried through sharp canine teeth as she was stretched even larger, his flared head pushed her cervix open. She felt him tense as he finally began to cum. Her whole body jerked under him as she felt him start filling her with an impossible volume of semen. Whatever small parts of her weren't filled with his monstrous cock were quickly filled with scalding jism. Her fertile womb was being filled with everything he could muster. The feeling of being filled...the pleasure... was...was...indescribable. She couldn't take it anymore. All her myriad muscles pulled taught as she threw her head backwards as she finally came.

"YOWLLLRRRARRHHHHHARRRR!!!!" she roared as her pussy clamped down on her horse lover like a vice. Her slick lubricating juices boiled as they mixed with massive amounts of virile cum, the mixture backed up out of her love canal as it became saturated. The mixture splashed the base of James's cock, soaking his stretched sheath and balls in their combined sex juice. The orgasm washed over her body. Shocks of orgasmic electricity jolted her as she lost all control over her body. She became a frantic sex-crazed machine, her only driving purpose was to squeeze as much out of James as she could. Her instincts told her she wanted to be pregnant. The wolf needed to be pregnant.

James's immense weight fell on-top of Claire as the orgasm washed over them both. If Claire wasn't so strong and well-built James would have crushed her, his equine weight substantial. Their legs pressed and kicked as they intertwined, unable to control their strong muscles. Both James and Claire weakly humped and ground their furry bodies against each other, riding the orgasm's powerful and seemingly unending waves.

James's balls sagged as they twitched between his thighs. They pushed smaller and smaller spurts of his semen deep down his expansive horse flesh. His cock was still hard inside her as it throbbed dryly. Claire moaned, unable to do anything but hold on as her body was continuously wracked by the orgasm. James's broad chest mashed against her breasts only made it worse as her sensitive nipples dragged through his fur. Each of the jutting sensitive nubs sent shocks into her still convulsing pussy. Her insides were so full, she couldnt...she couldnt.... Any thought she was able to hang onto was quickly washed away as James pumped his still-erect cock inside of her. They laid there like that, collapsed in joined sexual bliss, for hours. They needed each other. The searing pleasure still lanced through their bodies which made it impossible to separate even if they wanted to.

---

After what seemed like eternity James raised his head his heavily lidded eyes blinked slowly. He huffed through his wide nostrils as as he tried to get up. He caught by his still buried cock. With a moaning whine he wriggled his hips. Eventually he managed to pull out of her. A wet sucking audible "shhhloccck" sounded as his cock pulled out of the wolf's deep love canal. Globs of cum and juices poured out of her, like an uncorked bottle. Claire's heavy breasts rose into the air as she breathed deeply, no longer constrained by the immense weight of the horse on her body.

Claire convulsed and writhed weakly as the last aftershocks of their orgasm still washed over her, exasperated by the log of horse meat that dragged against her walls. James flopped back onto the floor and laid there next to her. They felt each others body heat on their fur, James turned to the wolf for a moment, his dazed eyes attempted to make sense of what was in front of him and were unable. The heat was slowly receding like a low tide. The fuzziness in his head was growing clearer and clearer by the minute as he laid there staring at the milk-drenched rise of Claire's bosom, the cum leaking slowly from the bottom of her still partially-spread lower lips.

"Hrrrnnhhh," he groaned as he tried to flip himself over, his heavy body ached. After numerous failed attempts he did it. His hands found purchase on the juice-soaked floor as his hoofs slipped and finally grabbed hold behind him.

His cock hung semi-erect between his legs as he rose, drenched with their drying juices, its broad tip touched the floor as he struggled to get to his feet. Carefully he brought himself upright, relying on his hoofs to anchor him on the slick floor, his weight shifted onto his legs. HIs legs shook as he straightened his back, his head rearing up as he let out a long huff.

He took a few steps, and then a few more, his hoofs clacked wetly against the floor. He didn't know where he was headed, but he felt compelled to move. He was unsure of himself, without his instincts to guide him the more rational parts of his brain had no experience with the strange new body that he now possessed.

James approached the door but suddenly his right hoof slipped sideways on the floor in a congealed pool of his own cum. He whinnied in surprise as he staggered backwards. His body became unbalanced as he struggled to stay upright given his immense torso. His legs kicked powerfully under him as he stumbled. Everything moved wrong. He tried and failed to catch himself as he lost more and more ground as he slipped backwards. Finally the angle of his body became too extreme and he fell in earnest. His breath caught in his chest as his body was caught by a soft, if not thoroughly soaked, mattress. Breathing hard he sat dumbfounded on the edge of the bed, he had no idea how he had made it all the way back. His broad ass cheeks sunk deeply into the soft material as his tails' long hair swept over the sheets. He nickered as his balls pendulously slapped the edge.

As he sat there recovering his faculties began to become his own once more. His eyes sharpened and became more focused as they shook off the glaze of lust.

"Huh..." James looked at his large thickly-nailed hands. He turned them over as he clenched and unclenched their strong muscles. His mind was ill-equipped to understand what he was seeing. "Wha....what happened..." James muttered as he unconsciously brought them up to his muzzle and rubbed his temples with his thick fingers. He looked down and saw himself, really saw himself. Jutting pecs partially blocked his view of something huge and wet that hung between his legs. It was impossible, he couldn't..this wasn't... His limp cock slowly receded into his thick sheath as he stared. The flat deflated, but still domed head of the shaft tucked itself into its fleshy home.

He wasn't thinking as his strangely large hands moved from his head to between his legs. The fingers inquisitively traced the outline of his sheath. He could feel the rubbery texture of the skin, the heat came off of it onto his digits. He pulled at the flesh, its edges revealed a wet interior, coated in the remains of slick sex liquids gleaned off his cock. The skin was surprisingly springy. He couldn't stop himself from nickering as he explored, felt the weight of the strange flesh between his thighs. He progressed upwards as his thickly nailed fingers traced his tight six-pack stomach muscles before diving back down to his pronounced male-hood. As he gripped his sheath he moved lower. His hand prodded the taught skin that connected to his ball-sac as it followed it ever downward. His hand carefully wrapped around the tightly-packed orbs dangling below as he attempted to heft their weight in his palm. He was unable to get his hand fully around one let alone the pair.

His delicate prodding and poking began to become rougher, more urgent. His mind began to be assaulted with reinvigorated animalistic desire as tantalizing pleasure coursed through his crotch. His left hand delved into his hot damp sheath as his fingers coaxed and squeezed his quickly engorging cock. His right hand preoccupied as it kneaded his balls.

"Unnnghhh...feels..." he whinnied, "Feels so...gooooddd..." he moaned, his voice rough and deep as it rumbled in his chest. His cock grew with a urgent insistence, his heart pumped fast in his perked ears. "Nnnnghhh...nooo...I cant...." he gasped as he attempted to stop himself. This was all wrong. He didn't know who he was anymore. He didn't know what he was. The panic rose in him like a tidal surge as he attempted to push his cock back into its home between his legs. His thick, still clumsy hands, only made it worse. Soon his flaccid length was easily a foot and a half long as it sagged towards the floor. He wasn't even fully erect and he had a log of cock flesh that was simply impossible. His right hand released his balls as it joined his left. Together they pushed at his mottled flesh, trying to force it down while he nickered from the stimulation. Shocks of pleasure lanced down his long length as it jumped with his fast heart beat.

While James was playing with himself he was too unaware to notice that his sister was on her long, padded feet again. Her voluptuous lupine body struggled the same as James as she had a hard time standing up, the deep ache of sex hard to get out of her muscles. Her thickly clawed toes found easier purchase on the soaked floor than James's hooves had. Her lupine nimbleness worked in her favor over the unwieldy horse. Her deep vagina further emptied itself as she stood. "Uhhnnn...Urrrrrhnnnnn!!!" she yowled as a cascade of still-steaming hot cum splattered out of her onto her thighs and the floor. Her hands pried at her mons, rubbing the ache out of her labia as she pushed out the overflow.

She glanced around the room as she still leaked from between the legs. Her eyes took in her surroundings as the fog began to lift off her mind. Her eyes found the horse almost immediately, just a few feet away on the bed, his cock standing to attention under his hands as they struggled to contain it. Her crotch began to leak as hot breath pushed out of her lungs. She felt the skin of her cheeks heat up. As small needful whining noises escaped her esophagus. The wetness in her crotch soon became a veritable waterfall of juices as she gazed at his engorging rod. The heat in her loins rekindled as it throbbed through her body. Her pussy washed the remaining cum out of her love canal. Wetness flowed down her legs in twin steaming rivers as it began to wetly splat onto the floor. Any hesitation about their species difference was washed away sixteen throbbing inches ago.

James saw a figure moving in the corner of his eye and looked up only to find the she-wolf at the foot of the bed. Her tits leaked down her toned body as her pussy throbbed visibly between her legs. She was...something. He couldn't quite remember as he shook his head. Sis...sister...his brain managed to eek out from behind the lust.

"N...Nnnoooo" he stammered through lust-filled fog quickly enveloping him again. "Sis...You have to...stop...I wont be able to..." he managed to choke out.

"To...oh...oh god..." he cried as he breathed her in, his cock jumped with every word as it aimed skyward. His body and mind were at odds with each other as his member quickly hardened. The flat head of the beast began to leak clear slick beads of pre over his hands as they tried to push organ back down.

"oohhhhh...you...smell..." he gasped as his nostrils flared as they unwillingly took her scent in. "Ss..smell...goooooodddd..." he cried as he couldn't help but luxuriate in her musk. His cock became fully erect under his hands as the flow of pre began to trickle down his length, pooling is it reached his thick medial ring.

Claire was much less conflicted as she wasted no time, her body nowhere near satiated by the session. If anything she needed him more now than before James had impaled her on his equine rod. She pounced on him with a playful and lustful growl.

"Grrrrhhnnn...so big...hnnnngghh!!!" she managed to moan as she knocked him over on the bed. She was on top now as she used a mix of her wide hips and her paws to guide his rock hard shaft to her engorged vaginal lips. She was too impatient to let the clumsy horse have a problem with aim again. As she slavered her pussy's lips with his slick pre she was satisfied with her guidance. She pushed her body onto him needfully. Claire gasped, her muzzle parted along with her thick walls as they gripped at his immense cock. She added his heat to her own. Inches upon inches disappeared between her powerful legs. Her pussy was still a tight, but it was easier this time. Soon he as deep into her as she could go, his throbbing head meeting her cervix as several inches of him protruded from her leaking lips.

The wolf collapsed forward onto James's chest, her breasts leaked all over him as they pressed into his broad muscled torso. She once more felt so full, so complete. The pleasure of him in her wracked her body. She growled in a deep satisfaction as her hips began to gyrate and grind. The horse was unresponsive to her body's movements at first but began to move with her after the first few thrusts.

They began to hump in earnest, slowly at first and then picked up speed, the horse doing his best to thrust as she bounced on his shaft. "Aaaarrwwlllllll!!!" Claire yowled as she was stretched over and over. "Urhhghh...tooo...too!!!" she cried between pleasure-saturated moans and growls, unable to complete her thought. Her juices flowed out of her unabated as they soaked James's crotch. She felt like she was being impaled, the horse's shaft was just too large for her to fully fit. Yet she persisted. She ground her body against his heat with everything she had. She felt him throbbing inside her, his domed head flared against her uterus, it drove her insane as she reared upright. Her hands gripped her heaving breasts as she rode his pole with wild abandon. Her clit dragged up and down the slick length as almost a foot of horse cock left and entered with every mad thrust.

James was being worked into a sexual frenzy. Thick foam formed on his lips as his eyes rolled wildly in his head. Any resistance had broken down the instant her vagina wrapped around the sensitive nerves of his jutting penis. The need was too strong and too primal for James to fight. He would take his mate. That's what she was now to his lust-addled mind, his mate. All too soon he felt his huge balls pull up towards his taint as a column of red-hot cum climbed up his long horse shaft. The magma reached the obscenely flared head buried deep in Claire as it swelled even further. He began to cum violently. Rope after rope of his seed pushed deep into her pussy as it filled her once more.

"nnnnNNNNNAAAAYYYY!!!" he bellowed as his huge penis saturated the werewolf with white sticky cum. He pulled her tightly against himself, his muscles bulged in the sexual release. The ropes lessened for a moment until his balls drew up towards his body and he came again, just as powerfully as the first time if not more. After the third orgasm her vagina could hold no more and it back-flowed out of her thick lips as they heaved with a fury, their juices splattered onto the overworked bed.

Claire maintained her grip on her breasts through it all. Her hands squeezed her nipples as hard as she could as she felt herself be filled. The pleasure overwhelmed her as fresh torrents of her hot cream pushed past her throbbing nipples. James grip on her tightened as they came together, he pressed her deeper onto him. Claire's eyes rolled into the back of her head, her long canine tongue rolled out of the side of her mouth as she was somehow further stretched, if only a little. He came again and again into her, a relentless beast built for sex. But so was she. Only four inches of him remained outside of her now. Her vagina was going crazy as it sucked and pried at the meat filling its every cavity and crevice. Splats of their combined juices and jism shot out onto the floor and streamed down their legs.

Claire followed her brothers lead as she came too. She thrashed as her body tensed, all her muscles hardened at once as she orgasmed. The orgasm was like nothing she had ever felt, as a human or a wolf. As it washed over her she felt an immense pressure from her stomach. Three new sets of nipples had formed on her tight furry stomach below her breasts. Her vision turned white as she continued to buck and drive her body on against James's gargantuan convulsing shaft. Her back cracked loudly as she grew in size, her body becoming more massive and feral. Large vicious teeth extended from her gums, her canines outpaced her mouth's ability to hold them. Breast flesh pushed out behind her new nipples as her rows of nipples became full-fledged teats below her main pair. Their sensitive furry flesh rubbed against one another as they became swollen with milk. The teats settled only a little smaller than her original pair. She had lost complete control of her body, it was no longer just an orgasm, but a heat frenzy.

"Guhh..guhhh..GUURARHHHH!!!" she roared more deeply and animalistically than ever had before. Her body thrashed, heaved and convulsed as she lactated uncontrollably from all eight of her breasts. A thick mane of fur grew around her neck and chest. Deep fur pushed out from between her cleavage as her body grew to almost match James'. Her pussy spasmed as it swelled large enough between her legs to fully hilt herself on James's huge tool, her body finally entwined with his. Her inner muscles grew stronger and thicker as she swallowed two feet of horse cock between her massive thighs.

James cried out in a series of high-pitched whinnies as he underwent similar changes. His orgasm-wracked body grew larger and larger under the huge wolf. His muscles tensed as thick veins snaked under his skin. His already large frame issued a series of cracks. Bones shifted and extended as his cock thickened deep in Claire. He quickly approached nine feet tall. His equine features became more wild and pronounced as his balls swelled larger between his thighs. His jaw jutted, it was too large for his muzzle as his long face struggled to catch up. His mane grew larger and longer as it pushed against the bed. The wrecking balls smacked into Claire's ass as she dragged her body along his length. His eyes rolled backwards, he couldn't stop himself, the cum spilled from him over and over.

The orgasms wouldn't end as their crotches splashed wave after wave of juices and cum onto the bed and each other. They could only hold onto each other as they rode each wave of painful ecstasy. They both reared their heads as the pleasure built and built. It was torturous. Their swollen bodies jerked against each other as a huge wave of pleasure washed over them. Claire's breasts splashed the last of her sweet wolf milk against James's chest while her crotch overflowed with a torrent of her brothers' thick horse cum. His huge, now empty, balls convulsed below her. The orgasm seemed like it would last forever as they both almost blacked out. Their minds were unable to handle the pleasure, the stress. Their breath was ragged and uneven as their bodies jerked against each other. Thankfully it began to end, their bodies thoroughly spent, having expunged the last of their substantial energy and sexual reserves. James's cock heaved dryly inside Claire as her dark engorged nipples still visibly throbbed. Claire's nipples managed to only form small beads of milk at their tips, their reservoirs exhausted.

Claire collapsed onto James once more. Her furry breasts jiggled as they settled on his chest, the boobs released the last few drops of milk onto his even more muscular chest. They both passed out almost immediately, the pair of lovers rested in a flood of their own juices. As they slept their bodies slowly receded into their human forms. Claire's huge mound and breasts receded into her frame as it shrank smaller and smaller. Her fur and wolf-like features gave way to her fair but fairly average complexion. Her vagina pushed out an obscene amount of horse cum onto the bed's frame as it shrank. Her multiple rows of breasts flattened into her body as her main pair shrank into a modest A-cup again. James's muscular physique gave way to his lanky and short human body as his massive cock twisted down to its original five-inch length. Both of them too deep in sleep to notice or care.
