it had been a few years since Tom started dating Sara. At 20 years old and about 5’8 with a head of thick dark hair, Tom was a pretty good looking guy. His frame had a decent amount of muscle. It wasn’t winning him any strong man competitions any time soon but he kept in good shape. Sara, on the other hand, could easily handle herself. She was just over 6 feet tall and had incredible strength to go with her melon sized boobs and long blonde hair. The two had formed a close bond.

Before they had gotten too serious, Sara revealed to Tom the main source of her incredible looks and strength. She was descended from a long line of werewolves dating back to 16th century Poland. While that had scared off all of her prior lovers, Tom had accepted her and found it incredibly hot to make love to such a strong, gorgeous woman. It was especially fun around the full moon. Sara would become insatiable and they would spend several sleepless nights that left them both totally exhausted, sweaty, and satisfied. Sara’s wolf had grown to love Tom’s gifted, 10 inch human cock. However, that would all change during her most intense heat.

Tom and Sara sat on a blanket deep in the woods at the edge if town, gazing up at the orange sky as the sun began its descent below the horizon and the full moon became more visible in its wake. Tom nuzzled up to Sara and prepared for their usual evening ahead.

“I love you.” Tom said softly as he planted a soft kiss on Sara’s neck, his hand resting on her waist beginning to slowly travel up towards her supple breasts.

“I love you too, babe.” Sara said back through a soft gasp as she felt his soft lips on her skin, her hand on his back gently applying pressure. Her lust began to awaken and she instinctively pulled him closer.

She looked up at the sky, the sun dipping lower towards the horizon, her instincts becoming sharper as she felt her changes beginning. She closed her eyes and sniffed at the air, a faint scent suddenly filling her nostrils. This was not the usual scent of the woods at night. This was something different that she could not quite identify. She did her best to push it out of her mind as she opened her eyes, her irises taking their usual yellow glow as she snapped them open. She looked down into Tom’s green eyes gazing back at her, their gaze locking as he brought his head closer for the first of many kisses they would distribute on their full moon nights.

As their lips touched, a wave of lust suddenly spread through her body, an incredible heat filling her as her entire body rippled with intense need. Her body began to tense up, a moan escaping her mouth as her lips parted and she sucked his tongue into her mouth. Both of her hands were now on his sides as she rolled them over. She looked straight down into his eyes, a wild lustful look overtaking her face as she glared down at him, grinding her clothed crotch on his expanding bulge.

As the sun set below the horizon and the moon began to glow brighter in the sky, its warm light showered Sara, the intense heat growing into a raging fire deep inside her. Her pussy began to swell as it immediately soaked through her shorts, juices copiously flowing as her need seemed to amplify exponentially. Tom felt his crotch covered in her hot, sticky fluids as he looked down to see her soaked pussy seeping through her shorts.

“Sara…are you okay? What’s gotten into you tonight?” He asked as he watched in amazement as Sara rose quickly, using the sharp claws emerging from her lengthening fingers to shred through her clothes.

“I don’t know babe. The heat feels so much stronger this time. It’s like I can’t even breathe.” Sara barely finished her wondered as she struggled with her primal desires. She brought her long, clawed fingers to her swollen pussy glistening in the moonlight as its juices continued to flow. She pressed her padded fingers to her clit and between her lips, a loud wet noise filling the air as she pressed in. “It’s so strong Tom. I can barely think.” She said through a struggled low, growly voice, her humanity barely hanging on as her urge to mate continued to multiply with each thrust of her large paw into her engorged, wet cunt.

Her change began overtaking her much faster than usual as she stood and pushed her chest out, letting out a moan that descended into a long howl, her paw soaked between her legs. As she howled, her body grew to a height of about 7 feet, muscles rippling over her frame. Her breasts swelled to the size of watermelons. A coat of snowy white fur emerged from beneath her skin, cloaking her frame. Her ears poked through the blonde hair on her head as they rose and became pointed. As her voice changed, her face pushed out into a long, furred shout.

Her howl echoed through the night sky, her tail shot out from behind her, immediately sprouting a thick, bushy coat of fur. She looked down at Tom, a lustful grin spreading over her snout, accentuated by the sharp, deadly fangs protruding over her lips. Her jaw fell open as she began to pant from her insatiable need.

As she completed her change, Tom could only gasp in wonder and fumble to remove his pants as she positioned herself over him, her gaze fixed on him. She let out a commanding snarl as she began to lower herself, the fabric of his jeans still blocking what she desperately needed as her pussy throbbed with growing need. His 10 inches of rock hard meat finally sprung from its fabric prison just as her cunt approached. His tip was immediately swallowed by the soaked, swollen lips. Her hot juices leaked straight down his full length. She let out a growl, almost frustrated grunt as she put her paws on his shoulders and immediately began to grind her hips up and down, her furry ass cheeks slamming into his crotch as she forcefully rode him.

Tom gasped as he felt his member become absorbed by Sara’s hot, swollen pussy. It felt so much wetter and tighter tonight than it normally did. As he tried to thrust his hips to keep pace, she looked down at him, a deep snarl escaping her muzzle as she continued to move faster and faster, her mind completely lost in her primal desire to mate.

Tom couldn’t help but notice something off. While she was all the time rough with him in this state, she was usually still loving and passionate. Tonight he felt more like her dildo than her partner as she furiously continued to lower her tight, soaked cunt onto his cock. He knew he wouldn’t last long at this pace as she continued to wildly ride and milk him.

Deep in Sara’s mind, what little humanity remained attempted to figure out what was happening. Normally Tom felt incredible inside her. But tonight, he almost felt small as she desperately tried to impale herself on him but was unable to get anywhere close to the relief she craved. Her animal instincts were in full control as she continued to ride harder and faster, feeling Tom’s poor, human cock getting so close even though she was nowhere near satisfied.

“Baby please. I won’t be able to last much longer at this pace.” Tom begged in desperation as he tried to hold on, his words not fazing Sara as she looked up at the moon again, her pace only increasing with her insatiable desire. She needed relief. She needed to feel it harder and deeper. She needed so much more than his human cock was giving her. Her pussy barely even felt stretched the way it usually would.

A few seconds later Tom felt his cock swell and twitch as he was sent over the edge, cum gushing from the tip. Sara was completely unfazed, feeling his cum rush in as she continued to buck her hips longer and faster. His cum rushed out of her pussy, leaking into his crotch and over his balls as her relentless riding forced it out of her.

As she felt him beginning to soften she looked down at him, growling in frustration as she rose up from his lap. Her pussy was still soaked, her lips leaking Toms cum. “Baby I’m sorry. I just couldn’t hold on. I tried to warn you.” He said as he noted the lust and frustration in her eyes, her feral need only intensified from her inadequate fuck.

Suddenly, her ears perked up, she lifted her nose and inhaled deeply, her heat intensifying further as she picked up the scent from before, finally identifying it. As it filled her, it made her whole body quiver, her pussy trembling with need from the beckoning scent. Her instincts took full control. Her humanity became completely buried in the deepest reaches of her mind as she turned and took off down the trail deep into the woods.

“Hey! Where are you going?” This was all she heard from her unsatisfying human as she neither stopped nor cared and kept moving towards the scent. After several minutes of running through the trees, she came upon a small, moonlit clearing. The scent immediately hit her much stronger as she emerged from behind a tree to see its source.

There in the middle of the clearing stood a muscular black werewolf. As she approached, he towered over her, seeming to be about a foot taller. Large muscles covered his entire frame, his eyes glowed a deep red in the moonlight as he looked over at her, a smirk spreading over his muzzle as he barred his long sharp fangs and glanced down at his crotch. Sara immediately saw one of his huge paws gripping the longest, thickest cock she had ever seen. It had to be at least 18 inches long and as thick as her wrist. At the base emerged a large knot atop two coconut sized balls between his legs.

She couldn’t help but lick her lips, her long tongue coating her muzzle as she continued to approach the magnificent beast in front of her. She was unable to stop herself as he gave his monstrously large meat a hefty stroke, his scent cascading off of the organ, a drop of pre glistening from the tip. Her soaked cunt leaked profusely as his scent engulfed her. She immediately turned, her instincts in full control as she lowered herself in front of him, her paws on the ground as she presented her needy cunt to him, inviting him to mate her. She turned her head, her eyes staring directly into his as she lifted her tail and exposed her swollen, dripping sex to him.

Any of Tom’s remaining cum had been shed to the ground during her frantic search for her new mate, her inner wolf instinctively rejecting it in spurts along the trail. Her inner beast longed to purge the insignificant human cum as she made her way towards something much better. She wanted nothing more than to be taken by the beast before her. Her body trembled in the anticipation of being mated to the incredible beast that now focused its eyes on her dripping sex, its red cock angrily pulsing as her pheromones washed over him in uncontrollable waves.

The wolf looked down at the female before him, immediately gripping her tail in his paw and pulling firmly. She let out a low growl in submission, lowering her body as she raised her hips. Her scent intoxicated him as it flowed from her soaked cunt. He inhaled deeply, taking in the sweet scent of his new mate. He stepped forward and pressed the thick, bulbous head to her entrance, his pre mixing perfectly with her juices as her lips spread to accommodate their new, welcome guest.

As his tip made contact with her lips, Sara felt incredible shocks of pleasure radiating throughout her body. The mere touch of her new mate drove her senses wild and sent a wave of pleasure and relief through her body. As he pushed inside her for the first time, she felt her wet cunt stretched well beyond anything she had felt before. Her walls clung tightly to his member as they hugged and soaked his huge cock.

She let out a low, feral moan as he pushed completely inside her, his knot touching her entrance as her pussy stretched around his thick shaft. It was the most incredible she had ever felt as her new lover’s huge cock fired off waves of pleasure deep inside her that Tom could never dream of touching. It was as though her soul was being pleased for the first time.

A satisfied grin filled her muzzle as she felt his huge paws grabbing hold of her hips as he began to pull back and then began thrusting into her. Each thrust sent incredible waves of pleasure through every inch of her body as her new lover forced his huge organ deeper into her, immediately reaching an inhuman pace as the sounds of his hips smacking into her ass echoed through the trees, muffled only by the equally loud moans and growls uncontrollably escaping Sara’s muzzle as she felt herself being truly fucked the way she needed for the first time.

With each thrust of his huge cock she threw herself back even harder, giving herself completely to him as she lost herself in the pleasure that now filled every cell of her body. She wanted to give him as much pleasure as he gave her. She needed to satisfy this incredible alpha male inside of her.

As Tom made his way down the path, he froze in horror at the sounds coming from the clearing. Feral growls and howls invaded his ears as ge approached. He parted the trees only to be met with the sight if his girlfriend being completely taken by the large, deadly black wolf. The feral moans coming from his girlfriend were ones he had never heard even during their hottest, roughest sex.

She was completely taken by him, her eyes looking back into his with a satisfaction he had never seen. Her long tongue was hanging well below her jaw and over her lips as she was fucked senseless and pleasured well beyond any limits she had ever believed efficient.

The male wolf looked to the edge of the clearing, Sara following his gaze as they both stared directly at Tom, not slowing down their furious pace at all. The male grinned at Tom as it moved a paw up Sara’s side and snaked around her. She happily rose into his arms, her back pressing into his huge pecs. His arms closed around her, his huge clawed paws grabbing at her watermelon sized tits. She let out a deep coo and licked at his thick, furred muscular arms. She looked over at Tom for a brief moment. Any feelings she may have had lingering for him being fucked away by the beast now mating her as the idea of even thinking of stopping her new mate repulsed her.

She turned her head back, looking up into his red eyes as she opened her muzzle. He looked straight back into her yellow eyes, his muzzle also spreading, both of them closing their eyes as their tongues darted into each others mouths and the sound of a sloppy, passionate kiss radiated briefly as their hips momentarily stopped moving, their mating nearing completion. Their eyes snapped open, Sara’s eyes now darkening to reveal an amber color as she became mated to her new partner. She inhaled deeply as she took in his scent now sinking into her fur.

As she pulled back from the kiss, the wolf reached between her legs, spreading them as if to show Tom exactly what was happening. Tom watched in horror as they resumed their torrid pace, Sara’s body trembling as her powerful orgasm built. Her pussy suddenly stretched wider than it ever had. She howled loudly as she forced herself back onto his knot, a loud slurping sound echoing through the clearing as his knot slid in and tied the newly-mated pair together. Tom could see the outline of his huge member inside her as it pulsed and began to flood Sara’s womb with gush after gush of hot cum.

Sara let out a loud, inhuman moan as she felt herself being properly bred for the first time in her young wolf life. Her entire body shook uncontrollably as her orgasm rippled from her crotch and filled every efficient inch of her body. Sweat coated her fur as she tilted back her head, a loud howl rising above the trees. She was joined shortly by her new mate as they formed a chorus of loud howls.

As she came down from her earth shattering orgasm, Sara paid no mind to Tom, completely in bliss as she felt her lover’s cock pumping his seed into her. As the male wolf came down from his howl he barred his long, sharp fangs. Sara instinctively tilted her head, exposing her neck to her mate as he sank his fangs into her. She cooed as another jolt of pleasure pulsed through her, her legs now weak as her mate tightly held her. As he pulled his fangs from her shoulder, two visible red holes glowed proudly in the moonlight. She nuzzled back into him as he licked at the wound, her paw reaching back and grabbing on to his ass as he lightly bucked his hips, still engaging with small thrusts as he remained tied to her.

They remained in their rut for several minutes before the male felt his knot finally start to shrink. With a loud pop, he pulled himself out of her, cum and juices spilling on to their thighs.

She gave one more lick to his muzzle as he released her from his arms and they both stood up. She immediately began to feel empty, her heat beginning to rise as they got to their feet.

She looked over at Tom, no feelings remaining as her now-amber eyes glared at him, growling as he slowly tried to approach. He stopped and backed away. She needed more, but not with this human intruder watching. She needed to be alone with her new mate. She turned her back to Tom, facing a trail that went deeper into the woods. As Tom gazed between her legs, she lowered her tail, shielding her pussy from his view. Her new mate smirked over again as the realization hit Tom. Sara glanced forward at the trail. Her new mate got down on all fours and trotted off into the woods. She lifted her nose, got down, and immediately took off after him.
