Before Rex had a name he was a wanderer, adrift in the world. He was just over a year old, a shepherd mutt born on the streets. His tan fur was marked with dark shapes, their uneven form showing his mixed parentage. Triangular ears stood tall from a large head to match his sizeable body. To him every day was about survival, a constant struggle in a world above more than his basic understandings. The year was 1946 in a town far outside the city of Chicago, the world still echoing from a great upheaval, a conflict whose end would only bring about more doubt and uncertainty across the globe.

Everything changed for Rex when he fell into a trap, a steel cage where he spent hours, panicked and nearly insane. Then strange men carried him away as he clawed desperately to escape.

The young shepherd mutt would be the unwitting subject of a scientific experiment. He was given large heaps of food, scarfing it down with great satisfaction. But his peace was short, he was carted to strange, frightening places and shown odd things. Electric shocks jolted through him, men yelled and smacked the dog as he struggled to understand the patterns leading to such pain. He was out of his world, and nothing seemed to make sense anymore.

One day Rex was strapped down and placed into a strange, loud machine. For nearly three hours he was in agony, his mind and body warped by some tremendous power. He felt like he was being ripped apart and reformed as he lay trapped in a seemingly unending hell. But within the haze of panic and terror something more was dawning inside the canines mind. His senses became sharper, his mind and body honed tighter than before. Old memories of his life suddenly came back, patterns and images whose meanings were suddenly clear to him.

When it was over Rex possessed an intellect he was not prepared for. He blinked and looked about to his captors as they hovered over him. He now understood the world around him, people, items, gestures they all suddenly seemed to have meaning, pattern and predictability.

He looked into the eyes of the humans, he knew what they were, why they made noises to one another, who he was and what had happened to him.

In fact Rex's intelligence was greater than that of the humans who stared down at him now. His rewired brain was suddenly capable of putting together a clear picture of the world from even the merest hint, an unprecedented ability to extrapolate and observe at lightning speed. His DNA itself was rewritten, still a dog but adaptive and perfected. Even his canine senses had become greater, eyes sharp enough to keep up with his greater awareness. He was now a being of great potential, but he was trapped, a prisoner of uncaring, cruel men.

Only minutes into his new awareness he was beginning to understand the human's words. They called him R-E-X often shorted to Rex, a code name from the Recombobulation Experiment that nearly killed him. They all gawked at the helpless dog, squinting as they sought to see some kind of change in the canine test subject.

His powerful yet naive mind nervously glanced about, trying to take everything in as the men around him clapped in apparent success, their subject was alive and aware, unlike their previous attempts.

Standing out amongst the men was a uniformed man in a hat, listening in Rex heard his name, major Brandon. He was the one overseeing this project, a military man here to check progress on this dark sector research.

The man ordered the scientists to go about their work, to get everything they could out of this one, as he phrased it. At those words Rex was feeling a new kind of fear, one which only an understanding and foresight of one's doom could bring.

Rex's experimentation had only just begun. From simple puzzles to invasive scans and probes. They wanted to know just how altered their test subject really was. The scientists never trusted the dog, sedation, muzzles and straps kept him from fighting back. The men would not hesitate to punish the dog for his defiance, hoping to scare the creature into complacency when he defied them.

But Rex knew better, he would never let them know just how much he really understood, bearing the pain day after day. The dog was already able to grasp the concepts and tenets of science for his continued survival. He could delay his inevitable destruction by letting the tests be inconclusive and inconsistent. He teased them with glimpses of unprecedented genius that kept his life valuable enough to keep a little longer.

Rex was strapped to a wall, only a single forepaw let loose as a simple puzzle was set before him. He had seen this item before, a simple cube containing colored squares that rotated, he had solved half of it before to appease the men, before jumbling it, as if the alignment was a mere coincidence.

But today his large paw smacked away the toy, only staring back at the cold faced man as they locked eyes in the test lab. Today he would not play their game.

A hard fist smashed into the dog's muzzle as he yelped, bound and helpless as the man saw defiance in the animal. He cursed as he raised his fist again, frustration trembling through his arm as he struck the poor dog. Rex winced as he endured each successive hit, he was through complying with these monsters. Today it would end.

Rex hated them all, from the uncaring Major who had doomed him, to the vengeful man now beating him and the quiet observers who sat behind and watched it all without a shred of guilt. They cared nothing about this pathetic mutt. To them he was just an expendable victim, a small step on a larger goal. A worthless life to exploit and destroy.

The furious man turned about, rubbing his sore fist as he searched for a more suitable tool to beat the defiant beast and sate his anger.

But as he turned back to the dog he saw nothing but an empty harness. Rex had been slowly working his binds ever since he had been placed here in the lab hours earlier.

Each member of the lab staff looked up in disbelief from their notes, just as confused. Rex always knew his greatest tool was deception, they underestimated him and they were about to regret every moment of pain they had caused him and every dog before.

Too late the scientists saw a Jar of corrosive liquid falling to the floor, a fluffy tail whipping around the corner as toxic gas began to billow up into the room.

They rushed to the door, but Rex had already pushed the emergency containment button, heavy doors falling into place as the men desperately banged on the hard metal seal. Only the cold stare of Rex met them through the small window as he held the button down with a firm paw. They knew who had just sealed their fate.

As Rex watched them die his only curiosity was if they were actually capable of regret, or if those pleas they made were just another moment of selfish desperation.

His paw trembled as he let go of the button before he breathed out, knowing his hell was finally over, jaw still bruised and stinging from the beating, teeth clenched as he finished the deed.

The dog would move on, mind now looking forward as he walked freely in the labs, preparing to destroy every document about him and the tests, he would be a ghost.

After the lab staff was killed it took a full day for the outside world to come to check what had happened. Rex watched from the nearby woods as the lab was cleaned then sealed. Listening in on a stolen radio as he heard it all.

It was considered an accident, the lab was to be locked down, the bodies removed along with important documents and research before everything would be sealed. Lacking the staff to continue the program it would be put on hold until some unknown date or when the lab might find a new use.

Rex smiled as the military vehicles pulled away, padlocks and signs left on the soon forgotten building. The lab was now his, tucked away from the local town and prying eyes.

The old lab was now a comfortable place for the dog, no humans around and plenty of quiet so that he may read and study in the library. The dog was able to scan over the books, reading, digesting and turning the page in seconds as he siphoned as much data as he could from them.

The sensitive or dangerous materials had been removed as the building shut down, but Rex had been sure to bury many important compounds and items, he would need them someday.

Rex was now on a mission, a master plan he had been contemplating since the day he awoke into his new awareness. Rex knew his canine body was still mortal, he would die, and with him the most advanced mind on the planet would be lost.

He needed to breed, pass on his gifts so that his children may finish the work he sets in motion.

The nearby town sought to Rex's need, neglected bitches were easy to find.

Rex found three females, A sturdy rottweiler, a heavy coated husky and a soft, friendly black lab. Each lonely, chained and nearly forgotten in the back of a human's property. Rex sought them out, knowing such dogs would not be tempted back to their neglectful owners.

The bitches adored their saviour, following him back to the labs as he spent night after night in their company, breeding and grunting against each of them, his loyal little harem.

Rex enjoyed the female's company tremendously, slathering his tongue over and into their ripe pussies as they bucked and shuddered. Unlike a normal dog Rex was careful with every gesture he made, purposeful and direct as the females squirmed under his paws. He quickly learned their favored spots and touches, the bitches were hopelessly loyal to their new alpha, tails swinging aside eagerly.

Despite his incredible intelligence Rex eagerly drooled over the panting females as his bulging knot swelled deep inside them, shudders of explosive pleasure bursting in his mind. So visceral, so grand as it was.

Sex, pleasure, love, utter gratification, they were all his. The feelings that had once been vague drives and urges in the dog's mind were now practiced techniques and purposeful rituals he carried out each day. Each night ended as the three bitches nuzzled around him, ragged panting turning into quiet snores as they drifted off. Rex never felt so gratified.

The females even began to lift their tails for him out of their heat, knowing the pleasure their new master could bring them with careful paws and tongue. And Rex adored them back, they were simpler beasts, yet they were honest in their deficiencies. Their thoughts were simple, but pure, a feeling he remembered well from before his ascension.

Rex found humans arrogant and uncouth. Even if they were bright, even having the spark of creativity that made them capable of great things. They were hopelessly flawed, their unrestrained power bringing themselves, Rex and other creatures great pain. Their unquenchable scramble for dominance was already taking its toll, millions upon millions dead in the largest war to date, even now another looming around the corner, powerful men grasping for things they could never truly hold and bringing millions of lives down with them. One day, Rex would make them pay.

Even as a stray he knew they could be dangerous, and now he knew just what they were capable of. A single shot from a firearm could end him, or a stray human stumbling upon the lab jeopardizing it all before it really began. If humans knew what he was he would find no peace, hunted until the end.

Rex's bitches bore him many children, the new mothers nursing and adoring their unusually intelligent offspring as Rex smiled at his beautiful family. Over the coming months Rex tested each of his children as he raised them, they indeed showed far greater intelligence than a normal dog, already almost as sharp as he was.

Rex was delighted to learn that he could communicate with his sons and daughters. When close they were able to call out to one another with their minds, and unlike humans who used sluggish words and sounds they spoke in pure thought. Rex and his children spent much time sharing thoughts, theories and stories with one another. An in depth conversation that took humans an hour to complete could be finished in minutes with their fast, efficient minds. The more Rex's brood expanded, the greater reach and understanding they would all gain.

Rex finally had equals. He told his children his master plan and easily trained them where to find the best foods and how to evade humans, sending them out to help gather supplies for his growing family.

His children were impressive in their ability, but like him, they too were limited in their potential, unable to manipulate items like a human, or communicate with them. They could never build the machines their minds could construct, test hypothesis without the tools and ability to do so.

Rex would need to find a new mother, one with the capabilities his children needed to thrive.

It was decided, he would copulate with a human female, seed her body and force her to bear a new breed of his children, for the future of his kind.

His abnormal DNA could accomplish the task, merging with the female's eggs to create a hybrid capable of everything Rex could not do. With strength, intelligence and ability there would be no stopping him, revenge would be swift.

But the act of breeding a human would not be easy, they were fickle, strange creatures. But luckily Rex was nothing if not persistent and resourceful, one way or another he would have his human bitch and seed her womb until it was bursting with the next generation of his children.

Rex had first considered taking a human bitch by force, his wits and strength would make it easy. But he would not stoop that low, not when there were many other, higher paths he could take. He would not be as desperate and destructive as the humans who had once terrorized him. He had considered all his options, and now was setting them into testable actions.

Rex would continue to use subterfuge, slip into town and play the dumb dog. There he would find a young, healthy female to be the unwitting mother of a new generation.

The large shepherd mix walked down the street, casually strolling as he set about his day. Rex was at home on these streets, he had spent his puppyhood here, now he was a master tactician on a very sensitive mission.

Rex and his four legged children had been scrounging the town for useful items and food. Rex had read many magazines and books on human mating and courtship. The big dog and his sons drooled as they looked at nude images of human bitches. Their furless, shapely bodies in strange mating displays across the printed page.

And within pages of flowery prose he read about their desires, fantasies and anatomy in raunchy books. The emotions, dark desires and perversions of the human female revealed to the canine.

Despite his disdain for humans he was gaining a real taste for human women, their softer bodies and kinder faces had never given him the harsh treatment human males had wrought upon him.

Many nights Rex dreamed of a human bitch between his thighs, his cock stuck deep as her body yielded to his bestial advance. He would lose himself in the fantasy as one of his bitches lapped at his engorged cock, a strong paw palpating himself as he prepared for that day, mind milling over all possibilities and complications.

Dead ahead on the sidewalk Rex saw his target, a young human bitch walking back from the local high school. She was clad in a formal school uniform, skirt down to her knees with a bag slung over a shoulder, holding books seemingly too heavy for her. Long brown hair hung down to her shoulders. She was on her final year of the local school, a prime age for fertility.

Rex could recognize the sway of the girls wide hips from a mile away, he had learned her name was Linda and she had become his number one potential female. The dog's eyes held on the girl's body as she walked ahead, paws silent as he approached, he had been meeting her on the walk back from school for over a week now.

But today there was something wrong, a human male was at her side, chatting with the girl.

Rex's teeth grit, listening in as he studied the male, a mere boy and a potential complication, a rival mate.

After only a few moments Rex's primitive fear was quelled, Linda held herself close, voice uninterested as she seemed to wish for him to depart. But the young lad didn't read the signs, instead he chatted about some kind of dance he seemed keen on.

Trotting tall Rex made a path straight down the middle of the sidewalk, surprising the young man and delighting the girl as he barged between them.

Linda quickly took the opportunity to shift attention, voice pepping up as she reached and pet the familiar mutt.

“How you doing boy? Who's a good boy?" She spoke, baby talking the dog as he leaned into her side, face pleasantly scratched.

“Whoa, your dog?" The boy asked, still a bit surprised at the sudden interruption.

“Well… kinda." She answered, feeling a bit like he was her's with how many times she had seen him recently.

“What is he?" The boy asked, perplexed to the dog's breed.

“He's a dog! And a cutie!" Linda replied, not knowing or caring about his lineage. Both her hands scratched up under Rex's neck, he loved when she did that.

Standing awkwardly for a few more moments the boy started to excuse himself, seeing Linda's attention completely pulled away.

“So… uhh.. I'll see you later, or something. Gotta catch my bus." He explained, running back along the sidewalk to the school and his waiting vehicle.

Rex sat smug and victorious, panting and wagging as the girl leaned down to pet his face. Rex knew many humans had a soft spot for dogs, an advantage he would exploit as much as possible.

Getting in closer Rex's nose gently pressed against her groin, inhaling as the strong scent of her human cunt hit his nose. The fabric did little to hide the scent of her body from him. Rex smiled wide as the girl did nothing to push him away, just petting his head. He was so close to just lifting that skirt and diving into her treasure. But the dog was in control, only lifting his muzzle to gently lap at her offered palm.

Within was a few scraps of meat he gingerly plucked from her hand while she smiled. She had begun saving a bit of her lunch for him, a gesture he did not need, but was happy to accept.

Rex's time with this girl was surprising, she treated him better than any human he had ever known, her touches were honest and kind, her voice peppy and excited when he was around. And in turn he too felt happy with her, the positive energy she held proving soothing to the canine.

Despite his fear and hate of humans there was a part of his species, this innate draw towards people he felt even now with his greater awareness. Every smile she flashed him, every candid moment they shared gave Rex a greater bit of satisfaction then he had ever expected to feel.

This girl was nearly perfect in many ways, an open personality and a young healthy body for breeding.

“Don't you worry, your my man." She giggled, resuming her focused petting.

“My special boy..." She whispered, directly into the dog's ear, not realizing he very much understood the context and meaning of her words.

Rex internally grinned at the remarks, the thought of this girl even casually equating him to a human lover was an important milestone.

Continuing down the sidewalk Rex casually walked at her side as she talked to him. She spilled her thoughts openly to the canine, unknowing the vast amount of information she was feeding to him.

She was aspiring to study life sciences, zoology being her favorite. And by the marks on her papers she could qualify for it. Rex admired her young mind, nothing to compare with his own but she was sharp for a human.

Nearing the edge of the town Rex saw the girl glance off into the woods, the trees stretching out past the edge of the neighborhood. Stopping for a moment she seemed to consider something.

“Hey boy… wanna take a shortcut today?" She rhetorically asked, glancing about in a seemingly nervous manor.

They had been taking this short cut for a few days now, the real reason Rex had stopped tailing his other potentials. He followed without hesitation.

They walked for a good while, making sure to be far out of sight. Finding a dry riverbed Linda descended as Rex sniffed about and took a full assess of the scene.

Then Rex patiently waited, the girl placing her bookbag against a tree and letting out a nervous sigh.

“This should work..." The girl spoke, glancing back and forth to make sure no one was walking across these woods to see what was about to unfold.

Expectantly Rex sat before her, making sure she saw his rapidly wagging tail and pink member poking from his body.

“Yeah boy? Does it make you happy?" The girl's voice quivered.

With nervous fingers she reached under her skirt, pulling her panties to the side, exposing her supple, young feminine lips under the hanging cloth. Linda's legs spread as Rex's head took no pause to dive up and under the skirt. Both her hands quickly grasp against the tree as she let the dog do his work.

His tongue struck hard against her moist slit, sliding up in an agonizingly pleasurable manor. The girl shuddered as she felt Rex's warm muzzle push so eagerly against her offered flesh.

OoOoOOh…" Linda moaned, feeling Rex's hot tongue press against her naked lips. Rex's head was fully stuck up her skirt, one last bit of concealment from the carnal, forbidden act she was letting him perform between her legs.

She stared down at the shape of Rex's large head pushing up the hem of the fabric.

“Mhhmmm… good boy… Lick this naughty girl..." The human moaned, stifling her voice as she choked back against the slow, deliberate caress her body was experiencing.

Nestled deep under the skirt Rex's tongue slathered over the human bitches cunt, feeling her lips quiver at every pass. Rex savored it as much as he had the first time under that skirt.

Rex had smelled it on her right away, she was a deviant, a pervert. Rex knew human females were meant to remain chaste, not even to touch themselves. Yet Lindas fingers and cunt held one each other's scent. He only needed to keep sniffing at her groin out here in the woods for her to have the idea herself. Then Rex happily and quickly showed her the most intense pleasure of her young life. Now each day she would grow anxious and excited, her body preparing for another lashing against his strong muzzle.

With Rex's attentions he felt her lips parting, vulva relaxing as the girls back pressed hard against the tree. Noting her advanced state he pushed harder, spreading her labia aside as his tongue dove in, licking from the supple entrance of her virgin vagina to the throbbing clitoris above.

After only three quick passes Linda gasped aloud, lungs pumping as she held in a heavy, pleasurable groan. She bit her lip, tensing as her body grew weaker, pleasure shuddering through every muscle. Rex's tongue felt amazing, the warmth pressing between her spread body, the soft fur brushing against her thighs and the perverse sight of the big dog stuck up her skirt.

She relished it, closing her eyes absentmindedly as she silently mocked the boys who would never perform such a lurid act on her. She was glad to let this stray mutt savor her body, now pressing harder as he challenged her to stay silent. Linda's mouth now held agape as a desperate plea escaped as a long moan. The waves of pleasure were building, her body seeming to grow warm all over even in the shade of the woods.

“Don't stop… oh god please don't stop..." The girl begged. Rex could feel her climax building, the trembling of her muscles, the unsteadiness of her body, the sweet nectar slowly flowing from her. He knew a female releases bonding hormones on orgasm, each time he made the girl cum he drew her biology ever closer to his own. A thought he relished and savored, her flower would be his.

Rex knew he could probably let her fall to the ground and mount her right now, pushing his swelling cock inside to quickly pump her body full of his seed. A small primal part of him begged to indulge, but his nose knew she was not yet fertile, he would need to wait and prepare her more for that important moment. And at how fast she was experimenting with him he wouldn't need to take her by surprise.

Upon Rex's muzzle he felt the girl's hands press down through the skirt, not trying to push him away, but to steady her faltering body. She now gasped and moaned out, leaning forward as her hips slowly bucked into Rex's supporting muzzle.

Rex had a new trick for her today. Pressing his upper lip against her clit, Rex let his strong tongue spear straight into her virgin cunt.

“OH!" The girl gasped aloud, falling forward as she pressed against his neck for balance.

Within Rex felt her walls contract around his invading tongue, squeezing him for a moment as she adjusted to the feeling. With a short pull of his lodged organ he felt Linda gasp, body shivering in pleasure as he expertly rubbed her clit inside his upper lip to tweak her oncoming pleasure.

Rex's knowledge of anatomy and his experience with his own bitches prepared him well to touch any female mammals buttons. He delighted as he felt her react to the even more intimate touch, his tongue tasting her depths as he pulled out only to push back inside like a pistoning cock.

“Oh god…" She croaked, her body penetrated by the slimy organ, its shape almost twisting inside of her, an entirely alien feeling that was making her knees buckle.

Lindas eyes grew heavier, legs widening as her weight was held by the canine's strong muzzle. Rex took it on, his superior strength pushing up as he unbent her knees, taking firm control of the girls writing body, playing her like an instrument.

Linda stared off into the woods, mouth agape as she shook at each thrust and withdrawal of the slippery hot organ from her body.

She had thoroughly explored herself before, but her probing fingers never felt anything like this. Was this what sex felt like? Pinned against the tree she felt her climax peaking within a haze of wanton, unbridled pleasure.

Rex lapped and pushed even harder into her spasming body, his saliva and her juices mixing within her soaked cunt. With her legs spread wide he was able to reach far, making sure to keep attention on her throbbing clit.

Rex scoffed at human males, their meager mouths and modest organs were nothing compared to his own. What woman would want to bed with a man after a dog like Rex showed her what a canine was capable of.

Rex continued his pace, thrusting hard as he tongue fucked the young girl against the tree. Chest heaving, Linda's dam finally broke, a jolt of electric pleasure surging up and over herself.

“Ahh! AHHHHH!" She cried out, forgetting stealth entirely in her haze. The girls vulva trembled against the canine as she came and shuddered.

“Good… dog..." The girl moaned out, struggling with words as she bucked and rode out the peak atop Rex's muzzle.

Rex felt his tongue squeezed as her body begged to be seeded. Still under the skirt Rex's eyes rolled back in his head as his own organ throbbed, begging to slip inside. To bask in her soft flesh and be pulled into her body in a union of interspecies intercourse, but not today.

Rex's focus was not broken, pushing, mashing and probing into Linda's soft cunt. Her voice was ragged, overwhelmed as Rex pulled the last echoes of pleasure from her.

“Mphh… mphhh… oh god..." The girl called out, her body still shivering with pleasure, the powerful tongue never relenting as it slurped below.

Rex slowly lowered the dizzy girl to the base of the tree, gently lapping against her moist lips one last time to soothe the exhausted female.

Panting himself Rex stepped back, emerging from the now very warm alcove of the girls skirt. There he sat down, feeling winded himself as he looked to Linda, who smiled back in a dazed way.

“That tongue… oh gosh that tongue..." She smiled, breaking into laughter at the absurdity of complementing the dog, her juices still dripping from his muzzle. This had started as a simple curiosity, but she was growing attached to this strange canine who also seemed to take quite a shine to her.

Letting out a long contented sigh her eyes drifted down, noticing Rex's erection on prominent display from his furry groin.

Rex noticed the glance and subtly moved his paw to better expose himself to her, hips pushing forward proudly to display his hanging canine member.

“Boy… come here..." The girl called, patting along her body as her eyes held on the surprised canine. Rex had figured it would take another few days before she was brave enough to try something like this. But as always Linda proved a pleasant surprise to Rex.

Eagerly Rex stepped forward, straddling his body over the sitting girl. He eagerly watched as she reached out, supple human fingers brushing tentatively against his well swollen sheath.

“Did I make you horny?" She asked, letting her fingertips feel the soft fur of Rex's groin.

“Is this, ok?" She cutely asked, one hand just barely sliding over his genitals, not wanting to surprise the big canine.

But her touch was very welcome. Rex parted his legs farther, than sat down gingerly on her belly to give better access to his protruding sheath.

Linda stared at the males equipment, the large, fuzzy sheath and a healthy pair of testes resting on her belly below. She had never seen a man nude before, now staring and marveling at the big dogs masculine endowments he presented without shame or pause.

Rex saw the marvel in her eyes. He knew humans would be unfamiliar with canine genitals, the alien nature and lewdness of the shape normally causing unease in people. But as Rex predicted Linda reacted with curiosity and wonder, happily holding around the rim of Rex's pouched member as her palm closed about his bulging shape.

With a instinctive buck Rex squirt a large glob of fluid onto the surprised girl, her touch gripping firmly around his highly sensitive knot. A shot meant to slicken a breeding females cunt.

“Oh! Did you finish already? Poor, neglected boy..." She giggled, feeling the hot liquid dripping down her neck.

Internally Rex laughed, he was only getting started.

Suddenly growing quiet Linda stared as Rex's cock pulsed hard in her hand, growing rapidly as another squirt shot forth.

Carefully Rex thrust forward, pushing more of his cock free as Linda held the sheath. She did not know how canine anatomy functioned, he wanted to show her his full glory, unsheath and let her fingers run over his exposed knot.

Squeezing from the sheath Rex's knot came free with a few well timed thrusts, almost scaring the girl as the pulsing organ burst forth. But her eyes held, fingers gripping on as she began to follow Rex's slow humps, sliding along the slick shaft and bulbous knot.

Human hands on his cock was a unique feeling, having only his own paw, canine tongues and a bitches hot cunt to pleasure him. Her skin was so smooth, fingers so small and gentle as he felt himself firm and squirt under her palms.

Linda grasped with both hands around the sizeable organ, marveling at it. The tip grew firm, its jutting point spraying his watery seed all over as the entire organ pulsed with masculine energy. The girl just watched as she touched her first cock, letting it spray over her bewildered face and now soiled blouse. One hand held around the big shape at the bottom, the other tracing along the shaft as she took in the feeling of it.

Rex just seemed huge, the blood red dog cock slowly thrusting at her face. Her hands continued to slide over the fully engorged, pulsing member. The skin felt taut and firm under the girl's hands. Rex was as hard as he could be, pumping his seed with regular pulses.

Surprised, Rex saw Linda open her mouth, letting him shoot against her tongue before her lips closed around his squirting tip.

Such a devious girl, so passionate and bold Rex thought, watching her return the favor to a stray dog like him without even a bit of coaxing.

Rex could hear her sucking him down, feel her tongue running over the tip of his cock as she smiled at the sheer devilish nature of her indulgence. Rex willed his body to pump harder, wanting her to taste him in earnest. And she did, one hand reaching down into her skirt, teasing her own body as she moaned around the organ for a moment.

Mouth dripping the girl pulled back, swallowing without a second thought as she let the canine cock fall from her hands.

“Wow that tastes funny." She quietly laughed, wiping her mouth with a sleeve.

Then her attention fell back to Rex as she saw him standing, back arched as his still heavy cock swung below. A intermittent splash of his seed shooting against the dirt between her legs.

“Wow? Do you ever stop?" The girl gawked at the mildly frustrated canine. He wished she kept holding him, but he would not complain to the inexperienced female.

Linda suddenly grew concerned as Rex continued to pant and squirt, almost in a trance.

“Oh god! Is it supposed to do that? Are you ok?" She asked, looking closer at the hanging red organ that seemed almost stuck, full to the point of bursting.

But Rex was fine, he just needed a moment to calm and slip back inside his warm sheath. He leaned over and happily licked Linda's hand, trying to let her know he was fine.

“Good, you seem ok…" She said, sitting back against the tree and finding her breath. She took the time to study the massive, hanging cock of her doggy partner. He was very long, his cock and large knot impressing the virgin girl.

She couldn't help but imagine what it would be like to have it inside her, the constant squirts filling her bit by bit. But she quickly dismissed the lewd image as impossible. Yet the idea had been planted, just as Rex wanted, to let her see his cock, marvel at it and let her inner animal urges crave it.

When the day was right he would mount her, the girl dizzy from orgasm and craving the next step. He wouldn't even need to knot her, a few healthy squirts of seed right down her fertile cunt would be enough to impregnate. But if he could he would give her the full treatment, knot her hard as she came around his overpowering flesh.

If that happened one day in these woods he would bide his time, watching from afar as her body took shape each day as he waited for the moment. The pregnancy would be quick like a dogs, by the time she could not hide it and before any girl could bear to tell anyone it would be due. Then Rex and his children would swoop in and whisk the pups back to the safety of the labs where they could remain hidden, the girl unlikely to even tell the absurd story. Rex could repeat this with as many fertile girls as he could convince to present themself sexualy in his presense.

But he really wished he could bring her to the lab, providing easy breeding for the dog and ensuring his new children's safety.

But that would be very risky, even if he got her there she would want to go back home, and if she talked it would ruin everything, forcing Rex and his children to abandon the lab and set back all their progress. But still Rex dreamed it could happen, stealing her away as she joined the family, belly full as she brought Rex many, many more children.

Rex could almost see it now, blouse pushed out as her belly swelled with a new blend of man and beast.

“We better just wait here." The girl spoke up, hoping Rex wouldn't wander off in his lewd state.

Minutes later Rex grew flaccid, slipping back into his sheath at the girl's relief. Her first adventure in dog anatomy was a bit of a learning experience.

Attention coming back to herself Linda noticed the wet splotches all over her once immaculate uniform.

“Oh no! You got it all over!" She said in a mild panic, realizing she had made a mess of herself in the most scandalous way possible. Her skirt had hid her soaked panties in the days prior but now she worried about walking back to the street with dog mess covering her.

But looking closer she realized it was not as bad as she feared, it looked like water stains more than anything else, and already it was drying. With a few wipes of her face and neck she felt better. If someone noticed she would say she got sprayed by the water fountain, it certainly looked like it.

“Ok boy, walk your girl home?" She said, sliding her panties back over her now drenched pussy and straightening the tilted skirt before grabbing the long discarded bookbag.

Rex wagged happily as he escorted Linda back to her house. The girl had asked her father if she could keep Rex. It was one of Rex's sub plans to secure her for breeding, he would gladly endure 'ownership' to get private access to the girl and closely monitor her developing pregnancy.

But her father did not like animals, refusing immediately to the girl's dismay.

Yet things were still progressing better than Rex had estimated, soon the plan would reach its next stage. She would be his.

Later that night Rex sniffed along the curb of the low class suburban street. It was trash day and a prime time to find devices and chemicals humans were throwing out. Rex was not above breaking and entering but he knew that such acts did not go unnoticed. So he and his children searched about, transporting back anything worthy of their attention.

But tonight his search was cut short as he heard yelling from down the street. It was coming from Linda's home. On high alert Rex rushed down the road, realizing one of the scenarios he had envisioned could be unfolding right now.

Upon reaching the home he heard the back door fly open as Linda ran out. Careful and silent Rex observed, seeing the girl crying as she rushed into the woods behind the house. Linda stopped behind a tree as she sobbed, legs tightening inward to her body protectively.

Padding over the dirt Rex got closer, listening as the girl sobbed pathetically against her sleeves.

Rex knew life was not good to Linda at home, long since losing her mother and now subjected to her frustrated single father. He drank a mentally corrosive liquid that often led to violent outbursts.

This was an unlikely opportunity, if her life at home was in turmoil she may run away from the house, allowing Rex to coax her to the labs where he could protect her and they could copulate in peace.

In the lab he could keep her safe and secret before and after the birth. This was a rare chance to unfold the plan with a great deal of security. Keeping a human pet for himself.

But as he looked to the sobbing girl something more primal stirred within him. He felt her pain, from the hopelessness, to the fresh bruise across her cheek. She was in pain, and she was calling out for help.

He realized it wasn't even about his plan, for the past few weeks he had grown fond of her, protective and almost parental. She too was a victim of an uncaring world, suffering pain at the hands of the recklessly powerful.

This world had failed her, and Rex was going to make it right. He put aside the odds he had calculated against this plan of action, if he played this right she would gladly stay at his side. And with her companionship he would have something he did not know he was missing until he met her.

Letting his paw fall onto a fragile twig Linda looked up from her soaked sleeves to see the large dog only a few feet away.

“Oh… it's You... Did you hear?" Linda struggled to say, wiping back her tears as she struggled to steady herself to the familiar friend.

“I'm… not okay boy." Linda admitted with a slow shake of her head, sniffling as she looked to the seemingly sympathetic animal.

Rex had read so many books about human psychology and sympathetic techniques. Yet as he looked at the tears streaming down her face, the tremble of fear and anger in her limbs he felt helpless himself. He couldn't stand to see her like this, He wanted to tell her he was going to protect her, show her things no human could ever dream of.

All the dog could do was step forward and give a gentle lick to soothe her bruised cheek. Under the touch he heard a struggling laugh from the girl, her emotions seeming now to spin about her head as the only one she could still trust in this world showed her a tender moment of canine sympathy.

“You're a sweetheart..." She spoke, struggling to smile as she pet the big dog, feeling herself calm on each stroke.

Then her arms fell around the dog's neck. Rex had a moment of feral panic as he felt her grab about him, restrained by a human once again. But he controlled himself, he could trust her, letting the girl wrap herself around him as her emotion broke again, crying into his soft fur.

Rex stood still, not knowing what else to do as he felt the girl let loose in his presence.

Behind the pair Linda's father could be heard yelling for her, his slurred frustrations echoing across the small neighborhood.

Linda cringed as she heard him again, a reminder to one of the many frustrations in her life.

“Damn this world… damn it all… leave me alone..." The girl weakly sobbed, she could not face him again. Rex protectively hugged back, eyes looking out to the house and the cruel man within. He had failed this girl, and Rex was going to take her away from it all.

“Everyone says I can't go to college… that I can't do anything..." The girl sobbed, getting to the triggering topic she had earned the fresh bruise for. Rex had heard humans were very picky about letting females do much of anything. Despite Linda's good grades and aspirations she was deemed unsuitable by many, another act of foolishness humanity perpetrated upon itself, to squander great potential with sheer arrogance.

“I hate it! I HATE IT!" The girl yelled out in an act of futile anger, not caring who heard, she was fed up with it all, she wanted it to just end. Her fingers tensed and dug into Rex for a moment before she calmed, feeling him hold fast against her.

A terrible shudder went through her, it was just as she had feared for years, her dreams were folly, she didn't have a future.

Rex held a paw about her, feeling the girl sobbing against him again. Strong feelings filled the canine, ones that no foresight could have prepared him for.

It was now clear to him, finding this girl wasn't just about Rex's master plan, he felt a real kinship with this weak creature. He now understood how some humans looked at their beloved dogs, wanting to protect them, see them happy and healthy, their mere presence a comfort. Perhaps she would prove even more crucial to him than he could have ever expected.

“What am I going to do..." Linda whined, voice exhausted and lost. It took a few moments for the dog to refocus and remember the plan, he needed to convince her to follow him. Everything else would fall into place from there.

Rex stood up, reaching out with his dexterous muzzle to pull at Linda's tear soaked sleeve. The girl almost unconsciously followed the gentle tug, rising to her feet.

“...You want me to follow?" She asked, Rex letting go as she heard the message.

“But Where?"

A loud yell from the house urged her forward, anywhere would be better than there.

So the girl followed Rex, drying her eyes as she walked. She looked up over the dark woods as the dog seemed to lead her on. She had heard of dogs leading people to important things before, and now she was prepared to go just about anywhere.

She was beginning to feel a bit nervous, the woods were dark and she seemed to be going further and further from town. But the destination was soon clear as the old laboratory building came into view.

On approach a short chorus of barks echoed from inside the fences. The excited voices welcomed their father as he led the young girl along.

A section of the fence had been removed allowing the girl to simply duck under to enter the yard. She smiled as the other dogs greeted her. She had always loved animals and their mere presence never failed to comfort her. And now she saw even more dogs looking out from the lab doors as Rex confidently led her forward.

She had never known where Rex came from, now she was surrounded by a colony of dogs, all seeming happy to see her.

The girl was surprised as she entered the lab, finding it clean and comfortable looking inside, the lights were on, carpeting laid across once cold hallways. Rex and his children had toiled to make everything as tidy as possible to please human sensibilities in the event of such a special guest. They had scoured the town and storage rooms for supplies, hooked the power back up along with running water through most of the facility after long labored efforts with their clumsy paws.

Linda stepped cautiously, afraid she was accidently invading someone's home.

“Hello..?" The girl called, looking about as only her echo and the sounds of panting dogs were heard.

Seeing how tense she was Rex moved over to a large record player. Grasping a certain record sleeve with his teeth until he carefully placed the vinyl onto the turntable. Then he hooked the record head with his tongue before jazz music began to play from the speaker.

Linda stared at the canine, blinking in disbelief at the very specific action he had just performed.

“Did you… just do that?" She hesitantly spoke, watching the dog reveal himself to her.

To her continued shock Rex's head nodded twice, in a very deliberate looking way.

Linda's hand came to her mouth, letting out a subtle gasp.

“You… Understand me? Don't you?"

There was another set of quick nods from the canine as he tried to give a big human like smile to the shocked girl, hoping he had not showed his hand too eagerly. She would be the first human to know his secret, and survive.

“Who lives here?" The girl asked, wanting to know if some master dog trainer was living in this place.

Rex's paw came to his chest, standing up straight as he gave a proud tap inward to his body, indicating himself in a way that was unmistakable.

“Oh my god..." Linda gasped, looking right into the eyes of the highly intelligent canine.

Almost if on que one of Rex's daughters pushed a large cushioned chair forward, with no pause to question the offering Linda sat down into it, her head spinning a bit as she looked to her canine host.

Rex let her breathe, knowing her mind was in great upheaval, trying to put this all together.

After a prolonged silence she spoke up again.

“What are you?" Linda spoke out in concern, suddenly feeling as if the world had just turned inside out.

Rex turned about, pulling out a suitcase from a shelf, Linda stared as he opened it after a few whacks of his heavy paws.

Within were many scraps of paper, news clippings, greeting cards, torn pages of magazines, just about everything holding text.

Finding a specific one he fished it out and set it into Linda's lap.

“Canis Familiaris - the common dog." Read the clipping from an encyclopedia, a small sketch of a dog along with more information written to the side. Rex was indeed a common dog, though there was more, as Linda couldn't help but notice.

“But… you're not normal..." She bluntly stated, watching as Rex snatched the paper back, diving into the suitcase for another item.

Rex had long since devised this method to speak with a human if need arose, the most efficient way to communicate in words more complex than yes and no. He had found most any answer or possible question that might come up.

A headline from the local newspaper was handed to the girl.

“Scientific breakthrough-" Read the ripped newsprint.

“So you are a dog… but… someone did something to you?"

Rex was able to give a quick nod. Linda was a bright one, easily able to read the intent behind these phrases. Though he was afraid it may be impossible to go into much detail to her like this.

Before she could ask another question Rex grabbed another slip of paper. It was a partly torn name tag.

“Hello my name is..." Read the text, and underneath in poor handwriting was R E X. The dog had written it with a pen in his muzzle, awkwardly scrawling it out. Rex had been the only name he had ever been given. Rex knew it would make the girl more at ease if she could call him by something more than 'boy'.

“Oh, this is your name, Rex?"

Rex nodded once again, hearing the girls disbelief settling into an acceptance to the fantastic situation she was finding herself in.

“My name is Linda… it's good to finally know your name, boy." she said with her usual, condescending tone to him.

“Oh gosh… is that rude? I am so sorry, Sir..." The girl quickly apologized, realizing that speaking to him like that may be belittling.

Rex simply moved forward, one paw on the arm of the couch as he gingerly licked at Linda's face, tail wagging all in a very normal dog fashion. He hoped she would realize he was very much a dog, such affections from her were cute to him, besides his mind was far above misconstruing such innocent intentions as anything other than endearing.

“So… I have to ask, why did you start following me? Why did you… you know..." The girl tentatively asked, hesitating to mention something so taboo outloud.

“I hope you don't think me as a freak… You don't have to lick me… if you don't want to..." She said thinking back to the first time she guided Rex's big head under her skirt, wondering if he would actually do it.

The girl was very used to judgment, authoritative voices scolding girls for being out of line. And now her secret furry lover had a voice and mind she had not expected. He was far more than a curious dog licking a tasty girl as she squirmed and encouraged his adorations.

But she would face no judgment from Rex, he too was a freak and his kind was far above such frivolous feelings of deviancy. Humans were prone to rationalizing ancient, outdated urges that came to their minds, Rex and his children were beyond that.

Fetching another scrap of paper Linda took a look at the offered clipping.

It was torn from the funny pages. A cartoon moose gestured forward with a speech bubble.

“Everything is A-Ok!" Read the overenthusiastic text.

Linda giggled for a moment at the implied tone the dog was giving, it did seem to match the fervor he had applied to her offered body.

In front of her Rex rolled his hips in a slow humping motion, panting as he showed off his excitement.

“You dirty dog you..." She laughed, feeling playful deviant. He really was her partner in crime, pining for another dive under her skirt. She had already felt his passion, but the fact that he was intelligent, that he knew it was taboo and did it anyway, how very naughty of him.

His own deviance made those past excursions even more thrilling for her.

Fidgeting a bit in her seat Linda gave Rex a focused look, smiling nervously, knowing her words were being heard this time.

“I had a lot of fun with you, and your really big.. Down there." she smirked, wanting to compliment her male accomplice.

“I was thinking about what we did all evening… until, Well, I think you know..." Linda said, recalling the events not long ago. The thoughts brought her back into the moment, her flight from her broken home.

On the shelf the record continued to play, in her shock earlier she had not even realized it was one of her favorites, a southern Jazz group she loved to dance to when her dad was out. And looking to the tattered record slip she recognized that it was her own copy.

“Rex… this was my record wasn't it?" She said reaching for the paper slip sporting the art deco image of a saxophone player. It most definitely was hers.

“I thought i'd never see it again… dad threw it in the trash… he said it was not fit for young ladies." She said with frustration, remembering the small fit she threw when he tossed it.

“Did you know? Did you save it for me?" She asked, smiling wide at her little lover having the same taste in music.

In truth Rex had not been thinking of Linda when he grabbed it from the curb. He and his children were simply looking for any forms of human media that may be of use to grow their collection.

But his nearly foolproof mind remembered the home he had plucked it from, and the scent that had been upon it. He was glad she seemed to appreciate the impromptu selection.

Reaching forward Linda leaned down to hug about the canine, this time her tone was joyous, humming happily as she rocked against him.

“Oh I love this one!" She shouted, sitting back up quickly, beginning to shake her hips as she stood, hearing the band kick in.

Rex stepped back, watching as the girl shimmied along, smiling as she danced. He took her cue, tail swishing to and fro as he too rocked his hips.

He had seen dancing like this in an old film reel, one which criticised new trends in dance as deviant and immoral. Rex relished that man's words, knowing many thought of such pelvic motions as a prelude to sex. He would gladly play along, joining Linda in this human courtship ritual.

“Yeah! Shake that tail!" She giggled, clapping along to the music as they both got more energetic.

Rex followed her basic motions, watching as her skirt swished back and forth, feet tapping against the soft carpet. He found it intriguing and strangely pleasing to join her like this, seeing her smiling and laughing because of him.

Linda's arms pushed out, palms upward as Rex obliged the obvious invitation, paws landing in her hands as he stood up straight. Rex was nearly as tall as she was, his strong muscles letting him effortlessly balance as his feet shuffled along with hers.

“Yeah! Feel the music!" The girl shouted to her partner. Hand in paw as they danced.

Rex's children and his canine harem watched the pair with rapt attention, keeping back as the pair moved about, feet tapping, bodies spinning about one another as the girl led the dog along. Linda had never had a dance partner before, and Rex was a quick learner and a passionate participant.

Paw in hand they continued to dance, Linda smiling and giggling as she let herself forget the pain and hopelessness she had felt earlier, she was now in a strange new world where she could just be herself.

Picking up the groove Rex began to lead, testing the girl as she twirled and danced along.

As the music hit a crescendo Rex pushed forward, one strong paw holding on the small of her back as he dipped the girl backwards, hind paws jumping in to balance them both. Linda gasped for a moment as she fell back. But feeling Rex's abnormally strong paw and seeing his happy, panting face in front of her the gasp became one of awe. Looking to the passionate, capable lover who was now holding her with incredible grace despite his quadrupedal body.

“Rex..." Her needy voice called out, a hand stroking gently across his face. And then as Rex had seen in human film he leaned his muzzle in, tongue kissing against her lips in a show of romantic affection.

Exhilarated, Linda pushed back, sloppily diving into her first real kiss. Their tongues met, Linda's smaller organ overwhelmed by the canine as he opened his mouth wide, covering her soft face with his thin lips. Linda moaned in the dog's maw, her lips kissing rapidly before she too opened wide, letting the big dog dive inside. She continued to push as Rex led her on, tongues dancing between them as dog and human embraced. Rex was finding this very pleasing and comforting, letting the girl melt in his paws, her soft lips pressing against him eagerly, his pretty girl.

Rex let her gently fall to the carpet, standing on all fours as the girl gripped hard with both hands around his big head, kissing sloppily and passionately against his ever lapping tongue. She was in his power, and loving it, she had never trusted anyone more, giving herself to the beast.

Out of breath Linda laid back, gasping and smiling before she rubbed her eyes. It was way past her bedtime and the dance had sapped the last of the strength she had. Above Rex's cock pushed defiantly against its confines, a bead of precum dropping from it as he panted. He knew he was close, so very close. But she was still reeling from this all, not ready to take him. But he knew it would happen, it was only a matter of time.

Giving a little bark Rex gained the girls attention, facing down the hall as she rose and began to follow. She was surprised to find a comfortable looking bed room, complete with comforter and fresh pillows.

She quickly realized she did not have her bed clothes, standing for a moment before Rex opened another suitcase to the side. In it was a number of female clothes, including a nightgown.

“You did all this..." She spoke, hoping to compliment her gracious host.

She didn't hesitate to undo her blouse and skirt, stripping down as Rex sat to the side.

Rex watched as the girls undergarments came into view, bra and panties blocking his view of her most tender skin. He had never seen her fully nude before, only getting his view from inside her skirt. He watched her bound breasts jiggle, the soft fabric holding them gingerly against her chest in a tantalizing way.

Then the show ended as the nightgown slipped over her head, it wasn't exactly her size but the girl was not one to complain. Perhaps she could sneak back into her house while her father was at work to get her things later.

Yawning the girl found the bed, lifting the blankets before looking back to the patient canine.

“Rex, can you sleep with me tonight? I'll feel better if your close." The girl asked, wanting to take him home ever since meeting him.

Rex didn't need to be asked twice, he eagerly came over, laying down next to the girl. His paws gently held to her front, curling slightly as she pulled the covers over them both.

“Thank you..." Was all the girl could muster as they both sighed and began the journey to sleep. Rex was used to sleeping with his harem and children, the dogs huddling together on the many soft blankets and mats they had gathered. Perhaps he could convince her to try it later, but for now he let his muzzle push against the girl, feeling her petting his neck as her motions slowed and then ceased, her gentle breathing in the telltale pattern of sleep.

The next few days Linda grew more comfortable with her new home. Rex had started using a chalkboard to write words out for her. The technique was slow but it allowed them to explicitly communicate.

He was able to introduce his children, explaining they too were bright, brighter than words could accurately explain to her.

She learned this was the lab where Rex was experimented on. He showed her to the large machine, its components long since gutted. Linda saw the canine shaped harnesses, the muzzles and flecks of blood dried on the wall.

It was something Rex hesitated to reveal, to explain so much to a mere human, such a thing could backfire. But he felt safe, and moreso vindicated to share his story with a sympathetic ear. Rex explained all that he endured. And with empathy Linda leaned down, hugged about the big dog and cried for him. Rex was touched in a way he had not expected, she apologize for the men who hurt him, hoped he never had to endure anything like that ever again.

These past few weeks with Linda were quickly altering Rex's beliefs and theories on humanity. Perhaps they were not all beyond saving, perhaps, the plan required an important revision.

On the second day Linda invited Rex to lick her again, feeling more secure in the walls of the old lab.

Her body nearly vibrated from excitement, hand caressing the canine as he went to work between her completely bare, spread legs. Linda looked down and saw Rex at his task for the first time, panties discarded as she sat on the edge of the bed.

Then Rex looked up to her, tongue slurping into her soaked pussy as his eyes held on her. She shivered at the feeling, he knew exactly what he was doing to her. She called out, encouraging the mutt as he sped up, hard eyes piercing her as his tongue reached deep, lips mashing about her trembling clit.

For the first time in her life Linda shamelessly moaned aloud, not stifling her voice as she gasped, shouted and came on Rex's relentless tongue. Outside the door Rex's sons listened in envy, their father had promised the time would come when they too tasted and plunged into their own human's. The survival of their kind would depend on it.

It was a week later Rex smelled what he had been waiting for. Linda's eggs were released, now traveling in her body, waiting to be seeded.

The girl was unaware of the fact, human estrus was much more subtle than a canines. But to Rex her body was exuding it, the smell an open invitation to the warm blooded male.

Rex bided his time for the moment, setting everything up while the girl slowly read her way through the library. Rex was thankful the military had seen the collection as not worth the effort to move.

In the old kitchen area Linda helped prepare a simple dinner for herself and the dogs, having a deadbeat father she was well used to the job, but now she found a special delight in the task, frying up meats for a small pack of thankful dogs. Rex was used to eating raw, cooking was just too cumbersome and risky for his paws.

Letting the meal settle Linda sat in front of the radio, listening to one of her favored programs as Rex laid on her lap. As the show came to a conclusion Rex made his move, leaning in to lick at the girls supple neck.

The sensation of his tongue never failed to peak Linda's arousal, she knew well how much pleasure it could bring.

She lifted her mouth, kissing against her canine lover as he drew her lust forward, the heat between them rising.

Feeling pangs of need Linda reached down the hem of her own skirt, slipping under the panties as an eager finger rubbed herself. But even that was not enough, she pulled at the clothing, fidgeting as she slipped the skirt and panties down, eagerly opening her crotch to the air as she kicked the garments away. Her other hand found Rex's groin, feeling the heavy testes as his own arousal grew.

“Mhh… Such a big boy..." She cooed, having handled his organ several times now. She delighted in it, the raw canine flesh pulsing in her hands as she returned the favor to her special lover.

Linda leaned back and spread her legs, letting the scent of her arousal and fertility wash over his nose. But Rex had other plans tonight. Now was time to ask the big question.

Linda was puzzled when Rex pulled away, standing in the doorway before he gestured her to follow.

Linda rose, finally stepping out of her dangling panties as she followed the big dog down the hall in only her blouse. She felt very naughty walking the halls like this, but the canine eyes on her bare crotch paid her no worry.

Rex reached up and opened a door, holding it for the girl as she stepped inside. The room was dark, save for nearly three dozen candles burning around the edges. In the middle of the room was a large mattress, red sheets on it. And upon it were rose petals strewn about, fresh looking and aromatic to the girl. In the air was music from the record player, a soft saxophone suite that cooed sweet intimacy to the girl's ears.

Behind her the door swung closed, Rex moving forward as he sat on the large bed.

“For me?" she asked, a bit shocked at the spectacle a dog had prepared for her.

Rex grinned as he saw the girl smile about the scene. He had taken the imagery from many books and magazines about female fantasies. He knew a girl's frist time was supposed to be special, almost ritualistic. And he wanted Linda to relax and offer herself, take the final step with him.

Linda stepped forward and knelt on the bed, seeing the red sheets glimmer in the candlelight, Rex's fur and bright eyes showing cleanly within the dark shadows and crimson light.

“Is this, a message? Are you wanting to say something?" The girl asked, knowing well Rex worked with intention and purpose.

Rex nodded, hips pushing forward as his pink tip showed prominently from his dangling sheath.

Bare knees on the bedding Linda could read the message loud and clear.

“You want to make love… have, puppies?" she asked, Rex having explained they were genetically compatible.

Rex slowly nodded, hoping to convey the seriousness he meant in the question.

In truth Linda had thought about it too, she had gone pretty far with Rex, gotten comfortable exposing herself to him. But she had concerns, licking was fine, but could they do it? would it hurt her?

“…Can it even work?" The girl piped up, unsure if that dirty little fantasy could be real.

“You know… your parts are very different, I don't know what would happen..." The girl continued, feeling a little lost trying to explain her concerns.

Rex had prepared for this, reaching to the side he grasped a magazine in his jaws.

Looking down Linda picked up the bound paper book, It's title and headlines were in spanish, but its contents were made clear by the image on the cover.

There was a drawing of a woman, clad only in lingerie sitting on a wide bed, a big hound dog at her side, their lips moving together in a frozen moment of intimacy.

Rex had been overjoyed when one of his sons had found it, a rare sight amongst the scores of conventional pornography discarded by jaded men and paranoid youths.

Opening the magazine Linda quickly scrolled to the page listed on the cover. Passing over similar drawn images and photos of women with various farm animals.

She stopped and saw the short story comic of the woman and her loyal hound. She could not read the text but Rex had learned the story well.

Her eyes went wide as she saw the drawings progress, The dog eagerly diving between the woman's legs just as Rex had done to her.

Then the woman rolled over, ass high in the air as the dog mounted her like a rutting bitch. The drawings showed the canines large, shapely organ pushing inside as the woman moaned and called to the animal. Then she saw drawings of the dogs organ swollen inside, stuck deep as he turned to finish cuming inside her.

Eager for more Linda kept turning, gasping as she then saw photos of women with real dogs on their backs, the animal's hips curled in the telltale posture of intercourse.

Linda felt her body getting wetter, it was possible, it was very possible. The girls attention quickly turned back to the present as she set the magazine down.

She was surprised once more as Rex held a roughly cut paper heart in his teeth. On it was Written the words 'I Love You' in his pained writing. The dog sat tall and wagged, using his canine charms to woo the girl in further. It worked.

“Oh Rex… I love you." She smiled. Reaching for the heart as she held it to her chest for a moment in a symbol of gratitude. She knew how hard it would be for him to cut and write something like this.

Rex had been very good to her, still the nicest boy she had ever met. She always knew her first time would be something special. And in this moment she couldn't feel any more special. She would do it, she would give her virginity to this extraordinary canine. The thought made her giggle, she really was going to do it and the funniest part of all it didn't seem odd to her, who wouldn't love this big handsome mutt she thought, this marvel of biology.

“Rex, let's do it! Lets bump nasties!" She almost shouted, giddy at the thought as her hands came together in a playful giggle.

Rex was pleased, he had known the topic was on her mind, and his patience had finally paid off, tonight the fate of the world would be sealed.

“Just, be careful… a lady needs to be eased into this." Linda whispered, hand finding the buttons on her blouse as she began to undo the last bits of clothing she had.

Rex didn't need to be told, he was going to make love to this girl, let her feel what it was like to be loved by the greatest creature on the planet. He would be gentle, protective and kind, she was very precious to him and he wanted her to feel it. He adored this girl and wanted her to be at his side, to help him shape the world to come.

Rex watched as Linda's blouse came off, the fabric pulled back as her bra came into view. The dog scooched closer as the music played on in the background, making the girl giggle to herself as she unhooked the bra.

Holding the loose cups against her breasts Linda laughed to her partner, she had not actually stripped her top for him before, Rex's interest so firmly focused between her legs.

Unable to hold the tease for more than a few moments she let her hand fall with the bra. Her breasts settled down with gravity on her chest, large nipples jutting out from the human mammaries. Rex panted, gazing upon the fully nude girl as her legs spread outward, hands on her thighs as she posed for the dog and let him take it in.

“Good boy..." She said with playful mockery, watching as he held himself back, waiting for her permission to touch her.

She pushed forward, hands combing through Rex's toned shoulders, feeling the fur slide between her fingers.

“Such an amazing dog." The girl whispered, leaning in as Rex tilted his muzzle, locking lips with the girl as he gave a slow caress with his tongue.

Reaching in Linda put her arms around the dog, inviting him close as he moved in. Linda cooed into Rex's lapping muzzle when she felt his fine fur brush against her pert nipples.

Seeking more she hugged firmer, feeling Rex do the same as his paws fell to her bare back. Her whole nude front pushed against the big dogs barreled chest, her breasts squishing between them as she felt the soft warmth of her lovers coat around her body.

One hand rose to his head, running her fingers along an ear as they continued to kiss, keeping the tempo slow as the music continued to play, its soft melody working to get the girl in the mood for love making.

Her skin pressing firmly into him Rex led her backwards, setting her down onto the waiting bedding like the delicate treasure she was. The fresh rose petals spread around her as the young girl relaxed. The candlelight flickered over her bare skin, her legs spreading wide as her canine lover laid himself across her body, his warm fur like a blanket upon her.

One last flick of his tongue to her chin and Rex moved down, letting little affectionate pecks of his tongue trace down her neck to the collar and onto a sensitive nipple.

Rex closed his entire mouth around her pert breast, holding it and gently squeezing the girl's flesh as his tongue probed at the prominent nipple and her sensitive areola. Despite his strength Rex was exceptionally gentle with his mouth, switching breasts as he kneaded the flesh in his jaw. Linda pet his head, smiling as Rex savored her nipples.

The ever licking tongue then moved south, the dogs warm paws now gliding over her thighs as he balanced, licking down her breastbone and taut little belly.

Linda leaned back, arms rising above her head as she let the dog in, feeling that warm wet organ pecking lower, her body trembling in anticipation.

Rex knew humans often favored this thing called foreplay, a bit of teasing and mood making to prepare a female's body. He was finding it quite enjoyable himself, assured to his success this night.

“Ohhhhh..." The girl moaned out, body turning slowly as the dog reached her groin, sliding down one thigh as he licked near her sensitive vulva. She felt him lap along each thigh, her muscles quivering as she got wetter on each stroke. He was teasing her, each lap moving one step inward until she felt him land squarely against her aching lips.

“MHHH!" She gasped in surprise, nerves lighting up as the dog hit her with that strong tongue, her body practically flying open to him.

“Make me a woman… make me yours..." She cooed, strong feelings getting the best of her, needing to express her inner most desires to her furry lover.

The initial steps completed Rex reached over to the side of the mattress for a moment. He dug his tongue into a jar of medical lubricant, cupping it with his tongue like he would water. He held the dripping, warmed mess until he pushed back into Linda's lips.

Aided by the slick concoction he slipped down right into her vagina, unfurling his tongue as the lubricant spread.

Working his tongue to spread the liquid gel deep Linda lay back, eyes closed as she smiled at the little jolts of pleasure he was giving her.

Rex pulled back, tongue slipping from her pussy with a wet pop. He watched for a moment as her walls clenched in his absence, working to spread the lube and ensure her first time was comfortable for the girl, Rex was rather large after all.

Eyes still closed Linda let her long body slowly writhe against the bed, legs spreading wide as the dog looked down upon his prize. Even for a human she was cute, a sweet girl he was about to claim.

Other humans would shriek in terror at the thought of what he was about to do to her, a violation of nature, the ultimate perversion. But Linda didn't care, she was with her lover, a capable and passionate male who she happily laid her body bare for.

Sensing Linda's arousal and anticipation at near maximum he moved in, Large paws hooking under her rear. Lifting her he angled the girls spread hips as Linda held her eyes closed, focusing on the powerful male that was positioning himself between her spread legs.

A pang of fear flashed through the virgin girl, it was really going to happen. He held her so strongly, the big male inches from claiming her. She could feel the heat of his body against her, her thighs pressed against his. Any moment and it would happen.

Suddenly she felt Rex's tongue lap across her lips, the dog seeing the nerves bubbling up in the girl. He wished he could speak to her now, tell her how much he cared and put her at ease for this special moment. But his simple gesture did the trick, the girl leaning up into the dog to return the kiss.

Rex held her lower body aloft, licking affectionately even as his hips curled into hers, fur against skin and flesh into flesh.

It was slow and gentle, starting with a warmth against her lips, its firmness apparent as it began to slide inside. Rex continued to kiss her, easing her nerves as he pushed further, her feminine lips pressed against his slowly retracting sheath.

Inside Linda felt the dog's hot member spreading her. It seemed so much easier then she had feared, the lube making the slide easy as Rex took everything carefully.

A normal dog would go mad with lust, thrashing and pumping to engorge himself as quick as possible. But Rex was here to make love, to ease the girl into womanhood and treat her body with tender care.

His canine cock was thin at first, engorging more by the moment as it began to fill the girl's tender body. Rex had already squirt inside her, the odds of a pregnancy increasing with each successive burst of canine seed flowing down into the girl's unprotected body. But Rex was going to make it one hundred percent, to seal her and pump all he had to offer.

Rex held the trembling, gasping girl in his paws, his hips making slow thrusts in as he felt his swelling knot slip into her lips, bottoming out inside the girl's spread pussy.

Rex held still for a moment, letting the girl take in the moment, her flower gone as the dog's engorging cock grew larger by the second.

“Oh god… it's in..." The girl stammered, almost not believing it, she looked down between them, Rex leaning back to let her see.

She saw her spread groin, Rex's fur pressed hard against her pubic bone as his bunched sheath held against her lips, his cock now engulfed in her young body.

Inside she felt Rex's cock pulsing with his masculine energy, his size now pressing hard against her body. The girl felt a tinge of pain, stretching for the first time as her muscles fought against the intruder in her body.

Above her Rex panted like a feral dog. His own mind was lost momentarily in the pleasure, his cock engorged and pumping larger and larger as he held awash in the primitive yet overpowering sensation. His first time mating with a human, not bad at all, as he would confidently say.

But he heard Linda wincing bellow, struggling to take the dogs big cock as her body fought it.

Rex expected this reaction, but he knew she could take it. Holding still and laying his body closer to her Rex let his warm fur cover her, his muzzle pressing against her neck as he invited the girl to hug him.

She did, wrapping her arms around and petting the big dog's smooth fur. Cooing she pressed her head against his cheek, steadying her breathing. Rex had her, her trusted companion. Being so close, feeling his fur worked quickly to calm the nervous girl.

“Oh Rex..." she moaned, feeling her tense muscles relax, surrendering to the canine member embedded inside of her.

Rex was fully engorged now, stretching the young girl's body as much as he could, he felt her sensitive flesh hugging around every inch of him, his knot sealing every drop he pushed towards her fertile womb.

A feral dog would have been done by now, just waiting out the tie as he grooved on the feeling it was pulsing into his brain. But Rex was crafty, he was going to use this time to give Linda her share of the pleasure. His hard cock could last longer then he would ever need.

Slowly and carefully Rex's hips began to move again. Linda's tight pussy struggling to follow along. Her feminine flesh flexing and contorting as Rex started into a slow rhythm, his large head now pressed hard into Linda's neck he arched over her nude body.

Shuffling and angling Rex's bunched sheath pressed against the girl's lips and up into her sensitive clit. A twinge of soft pleasure flew through the girl as she felt Rex's hot furry sheath rub against her, his massive cock slowly contorting her body. Her clit was well simulated, the knot pushing out from inside as Rex's fur pressed down outside in squeeze in a way she had never experienced.

It would be a challenge, to build her pleasure like this, careful not to move too fast and tweak her nerves, causing a painful clamp. All the while hitting her buttons and tuning her pleasure into a climax would be a challenge Rex was prepared for.

Rex tested his possible motions, left right, up down angles and patterns. Each one he analyzed her reactions, finding the best combination as he set forth.

The big dog's hips made small pecks forward, little jabs ending with a circular motion of his hips and an opposite motion pulling back before repeating.

The girl gasped, legs spreading wider as the big dog humped strategically, each motion building up into a lip quivering pleasure.

She never felt anything like it, Rex's massive powerful body on top of her, pinning her as his over engorged member filled her pussy, each motion now making her moan as he plowed into her with his massive cock.

She couldn't speak, only staring to her canine lover as his piercing eyes looked down at her, studying her emotional state and level of pleasure as his hips picked up speed, sensing her peak closing in.

Linda panted like a dog as the canine had his way with her, her chest heaving against his, her fingers like claws, scraping against his well toned back as she arched back against him.

And then with a strained gasp it hit her. The well overflowing as the girl gasped, out of breath as her whole body lit up, the peak of sexual pleasures.

Gasping, the girl regained her breath before she lost it again, moaning out Rex's name as his hips continued to hump, twist and pump. Rex stared down into the girl's desperate face, pleasure well beyond her control as he took her away.

The dog smiled, she was very cute to him, writhing against the sheets as her own primitive sexual urges took over, in these moments wanting nothing more than the sweet pleasure rocking her body.

And she got it, Rex not relenting as the girl grew dizzy, smiling madly as she pushed, arched moaned and trembled against him as her mind reeled, words escaping even her thoughts.

He was rocking her world, grasping and pushing her as her face contorted in screams of pleasure, moans of desperation and cries of ecstasy.

Linda grew weak, nearly passing out as the dog kept pumping into her. Rex wanted to push her far beyond her normal limits. He was an expert tactician, a scientist and the world's most capable lover.

Nothing more than a weak whine escaped the girl's lips, spittle falling down a cheek as she rocked lewdly against the sheets. After a few more moments of pumping Rex finally relented as he let her hips fall, his own carefully following as he lay across her belly.

Rex was submerged in her hot flesh, his heavy testes resting against her body as each pulse filled her a little more.

Rex stood his neck tall, paws falling to her heaving chest as he posed above, looking down to the girl as she looked up with bleary eyes.

Rex cocked his head, one eye looking down as a toothy grin crossed his muzzle. He looked absolutely smug, self assured and to the girl's eyes, deserving it all.

The girl felt her body tremble again as she watched him sitting victorious over her conquered body. And what a sweet victory it was.

“Rex… you handsome dog… you stud.. You GOD!" The exasperated girl called up to the ascended animal. She was in the throes of emotion, the pleasure taking over her thoughts as only these moments seemed to matter.

Rex got even prouder at her words, she had called him a god, the highest title any human could give to someone. A being of great power, far greater than mere humans. Rex would take the apt compliment with pride.

Wanting to show his own appreciation he leaned down, meeting the girl's lips as he gave a slow, gentle kiss to his beloved human. Rex let the mood calm as the girl sat back and caught her breath. Her body still trembled, the echos of pleasure still reverberating as Rex's rock hard cock held inside of her. Rex could have kept going, his stamina unmatched, but he would have mercy on the poor girl tonight.

Linda lay, relaxing as she pet the dogs shoulders, it was a full ten minutes later that she felt Rex get up, pulling his well spent cock free as his own fluids dripped obscenely from the hanging organ.

Linda adjusted herself against the bed as she felt the sudden vacancy in her loins.

Rex observed the slow drip of canine seed from the girls well stretched lips. He had given her a full load, her eggs already being swarmed by his abnormal canine sperm. Inside they would penetrate the cells, their nature shifting and bending the DNA to suit them. It would pick useful traits from the human, molding it before their DNA would fuse, bringing another form of life to the world.

Rex was never happier, his plan unfurling, and now a human girl he adored was now hopelessly attached to him, her hormones going wild in her mind, bonding her to her canine lover.

The girl reached up, stroking the proud dog as he stood next to her, the flicker of the candle light setting the scene as the young woman sat up.

“Rex… Rex..." she repeated, reaching out again to hug him. She was almost like a child, desperate for his attention.

“I love you.." She spoke, body nearly humming as she stroked the dog even more. She had given her virginity to this wonderful mutt, and she was grateful for it.

Rex held himself against the soon to be mother. He would treat her like his queen, anything she wanted, needed would be hers. She would have every comfort and curiosity that fit her fancy. And soon her belly would swell with life, the next generation of his evolving kind.

Attention shifting back to the present Rex felt the girl push her lips against his erect ear.

“Would you like to go again..?" she whispered with a rising lust Rex could already smell.

His only response was a firm wagging tail slapping happily against the bedding.

Letting go Linda turned around and got on all fours, her knees spread eagerly, pussy still dripping as the girl's shoulders hit the bed, head craning back in utter surrender to the dog as her hips jut back.

“Take me… " She begged.

The girl's breath got ragged as she saw Rex saunter forth, grinning with his sharp teeth as he considered the girls presented rear.

She was practically hyperventilating, the mere anticipation driving her utterly wild as he slowly stepped, stalking her like a feral beast. Rex could afford to forego foreplay this time.

Gingerly climbing up and hooking hard around her hips Rex let his cock push in gently once again. He still didn't want to overwhelm her, her human pussy still accommodating itself to his impressive member.

Rex and Linda panted in near unison as he slowly and expertly drilled her from behind. Cock surging again as he filled her to the brim, rich cum sloshing inside as the girl moaned, her body vibrating with his quick powerful thrusts. Rex was sure she would bear him many children, her body crying out for more and more.

With his senses and intellect Rex was able to mold her pleasure in each moment, tweaking her as easily as one would tune a radio.

Under the targeted assaults Linda's body caved again and again, shaking as she gasped, arched and moaned for her lover. She called to him, voice desperate. His precise motions extending her pleasure while her body screamed out in joy. Some part of her knew this was a special time, the hot cum spraying into her and fueling some primal fire that was filling the girl with unbridled ecstasy.

The record had long since finished playing, the room filled only by Linda's impassioned moans and Rex's panting as the candles burned low.

The girl laid out with her rear high, head against the sheets as she felt the canine holding deep inside her body. Rex's forepaws squarely pressed down on her upper back, her pussy hanging from his thick knot. He had found this position useful, having spent many long minutes pistoning into her as he pushed down, Linda moaning and gasping at mercy of his tireless motions.

The tie weakening the girls hips began to fall, sliding down and off Rexes long cock as he remained standing above her.

She lay flat on her belly, a thick string of seed connecting her genitals to Rex as he once again lauded over his victory. He wanted to go again, his experience with his trio of estrus crazed bitches having well prepared him for the duties of a stud. But he would withhold, the girl too exhausted to even ask.

Seeing the girl utterly spent Rex moved to grab a blanket, and pulled it over to the girl as she rolled over groggily. He then fetched a pillow as Linda placed it under her own tired head.

Then he lay down, nestling up to her nude, sweaty body as he pulled the blanket over them both. She hugged around the canine again before she fell right to sleep, soft breath against her lover. Rex grinned as he too settled.

A month later Linda hummed in the library, relaxing with a book in her hands. She had adjusted well to this new life, Rex nestled against her pregnant body.

It had come as a surprise to the girl, noticing her expanding belly one day as Rex handed her a “Congratulations!" greeting card with a stork, confirming her suspicions that it had actually worked.

She was shocked it was true, a scientific impossibility now happening in her own body. She was freaked out at first, hormones and thoughts bouncing in her head. But Rex's commanding presence put her at ease, letting her know this was planned, that she would be taken care of.

In the coming time the girl got comfortable, reading, listening to the radio and “talking" to rex with the help of the chalkboard, he had much to teach her. All the while Rex watched as she walked about with her swollen belly and tits, leaving herself bare as Rex studied the development of his new children, the key to everything.

They had been continuously making love and the pregnancy gave no pause to it, Rex now holding the mother to be gently as her belly pushed up, swollen breasts bouncing as she moaned to her lover. All the while they prepared for the big day.

And then it finally happened, Rex soothing the girl with medicines and his comforting presence as she gave birth. Thankfully for Linda Rex's pups were born smaller and less developed than human baby's, letting the experience being much less traumatic as pup after pup emerged.

With help from his children and loyal bitches they cleaned the wiggling pups, marveling at their form.

Laying down they looked like newborn pups, little shepherd mutts. But their bodies had a different shape, paws and torsos made for walking upright, digits grasping out and clinging to their mother as she fed them with the help of Rex's loyal bitches, still nursing their own pups and having nipples to spare for the hybrids. Even as simple dogs the bitches adored the new life, licking affectionately at the growing family.

Everything had fallen into place, soon the new pups would grow, learning quickly as they mastered their bodies. The world would never be the same.

Author's Notes: This was an interesting one, may even write more if I can find the time.

As always tell me what you think, I like writing zoo stories and It would be neat to follow Rex's sons and daughters in their own quests for new genetic material from the unsuspecting populace.

Edit: I made few modifications to the text, added some extra details and fixed grammar issues. The characters/plot is exactly the same but I wanted to add a few details that will be relevant as the story goes on. I considered updating some other elements after critique but have decided to just move on and let the story be as it is, hard edge, initial misanthropy and all.
