If Riley lived through this, she was going to have some harsh words with her service provider. Cell Phones were explicitly invented for long-range contact in states of emergencies, so of course, there would be no signal out in the middle of a national wilderness park. Nothing like paying forty bucks a month for one of horror movies worst cliches.


That was just one of a laundry list of problems the young woman's impulse decisions created for her adventure. Riley had hiked through this park dozens of times every year, even camped in it during the warmer summer seasons. She knew the trails better than the freckles on her arms, which in turn made them incredibly boring. Even the rough rocky paths were starting to feel like a routine trip to her muscular fit body.


It was going to start being difficult to justify the gas and supply costs to keep coming out if a gym membership could have the same experience. Luckily, the discovery of an off-road tire trail dug into the soft earth looked like an excellent deviation from the norm. Driving was illegal inside the park, but the prospect of finding new places in nature to chill out entice Riley to follow it.


That was six hours ago. Somehow Riley had wandered straight into the only dead zone this whole forest possessed. Without help from a GPS or any signs of a familiar landmark, she became hopelessly lost in no time. Now with the sundown and a full moon hiding behind clouds, finding any familiar landmarks to navigate from in the dark would be a snowball's chance at best.


Going camping with nothing but light clothes and three energy bars did not seem ideal, but the muscular athlete had been through worse. The most professional athletes still had their limits, and the sweat seeping off her exposed skin was not doing Riley any favors in the chill breeze. Maybe another half mile before trying to find a groove or something to huddle in. Logically speaking, she was bound to wander back into coverage range eventually.


Or find other people out in the woods, apparently. That was an almost hopeful prospect, if not for the previous thoughts on horror movie tropes. As Riley squirmed her way through some tight clusters of ivy orange light beamed between tree trunks to illuminate the dark woods like an early sunrise. Shielding her sensitive eyes to this sudden brightness, the lost hiker wandered closer to find a small clearing with a log cabin being the source. Oil lanterns were set at its many windows providing the area with enough light for a city block.


Spotting the large jeep parked in front of the makeshift lodging explained one mystery to the trail, only to raise six others. Off-roading was severely restricted, while actually living in the park was most likely illegal. Whoever was trying to hide out here could not have a good reason for doing so.


Riley felt better about the groove camping instead, except the scent of grilled meat caught in her nose. Her stomach did a backflip as rock hard abs crunched in protest for some protein. Of course, there was always the chance these were just some casual folks enjoying a weekend out. At the very least, she knocked on the door confident enough her biceps were enough to overpower any creep skulking out here.


That feeling waned as the door creaked open. A dark silhouette washed over Riley, obscuring her vision with a wall of tan fur in a tight tank top and jean shorts. The human blinked dumbstruck at the dense layer of fuzzy abs before craning her head back, taking in the round globes of breasts straining their cloth covering. She continued gazing up to meet the equally surprised stare of an anthropomorphic fennec.


The bigger animal woman regarded Riley with a flick of her ears and then leaned out to peer around the clearing. Her human visitor promptly backed out of the muscular giant's shadow regretting many decisions made tonight. Normally there was never an issue with the 'furries' she encountered in daily life, but Riley was six-feet tall, could curl a hundred-eighty pounds, and jog twenty miles a day. This fennec had double that on her with an eight-foot tower of bulk.


Riley had no idea what they were scanning for, but when they did not find it, the fennec leaned back to regard her with deeper confusion.


"May I...help you?"


"...huggah baba wah?"


Smooth first impressions were one of many things Riley was not good at, right below her sense of direction and pathfinding.


"Yeah, I get that sometimes." If it was any consolation, the random gibberish blurted out made the fennec relax with a soft chuckle. She brushed her thick red bangs aside regarding Riley seriously again. "But really, who are you?"


"Who the heck is out here at ten PM, Robin?" Another voice cried from somewhere inside the cabin, making Riley nearly squeal in surprise.


The fennec woman, Robin apparently, never took her eyes off Riley as she leaned back to reply, "Uh, it's some girl. A hiker by the looks of her gear."


"Wait, seriously?" Another anthro woman shoved Robin aside to squeeze into the doorway. This time it was a wolf a bit more on the shorter side of the spectrum. A white shirt and jeans hung off her slender frame like a tent, except, of course, where ample hips and a titanic bust stretched them into a tight wrapper. "Who is she? How'd she get here?"


"That's what I just asked, ya goof!" Robin made another sweeping glance past Riley. "I don't see or smell anyone else. This might be dangerous."


"I, um," Riley shook her head to snap out of the stupefied daze meeting two canines put her in. "M-my names Riley and yes, I was hiking this afternoon and got a bit lost. What do you mean by dangerous?"


Robin recoiled, but her companion quickly stepped forward with a friendly tail wag.


"This is a forest, obviously. You're lucky you haven't already been mauled by a cougar or bear." She gave Riley a comforting pat on the shoulder, black nose wiggling in rapid sniffs. "I'm Vivian, and that's Robin. I'll be happy to give you directions back to the main lodge from here. Shouldn't be more than another hour hike."


"W-what?" Riley blinked, feeling her heart land in her stomach. Just the thought of more hiking made her tenderized legs tremble in fear. Somehow resting with the giant talking animal women seemed a safer bet. "You just said there were dangerous beasts out here and it's freakin pitch black. Can't I just crash here with you? Please? I can pay or whatever."


Vivian bit her lip, her braided hair whipping about as she glanced into the sky and back to Riley. "W-well, we kind of hoped for a quiet evening alone. You know, being out here and all."


"...oh." Riley instinctively followed their gaze upwards in curiosity. A few patches of stars were visible in the breaking of clouds, with the first slivers of a full moon becoming visible. She really was not interested in pressing for elaboration on their plans.


"Don't be cruel, Vivian," Robin said, suddenly reminding Riley of her large presence. The fennec looked no less happy than her friend but was moving aside to make space in their doorway. "We can't just send her to sleep in the cold dirt."


Vivian whirled to face the fennec with her muzzle hanging open. "Are you serious!? The moon will be out any minute, and we...uh, she can find her way easily back in some fresh light."


"Not with predators about to become very active," Robin said, narrowing her eyes into Vivian's conflicting stare. "Might as well bunker down here and ride out the night to make things simple."


The canines stared each other down with such intensity that Riley almost volunteered for a midnight hike. Before that could be an option, Vivian gave out an exasperated sigh, latching both hands onto Riley's arm with a surprisingly firm grip. Despite her best efforts, the bigger human could not wench herself free while being half-pulled, half-dragged into the cabin.


Inside, the cabin looked about as practical as it could, with two people throwing it together in their spare time. Roughly cut boards made up a floor with several rugs laid about, set under essential furniture one gets at WalMart, folding table and chairs, cots, and a portable stove. At least ten barrels of water were piled into one corner. Next to them was an HDTV displaying a game of Smash on pause, of all things.


"I'll get that for you," Robin said cheerfully, relinquishing Riley of her backpack as they took in the simple accommodations.


"I'm not taking responsibility for this," Vivian grumbled as she released Riley. Her gaze drifted back to their guest with a grin, looking eerie in the many gas lamp lights. "But, I guess some fresh company couldn't hurt."


"W-what?" Riley rubbed the red spots Vivian's finger pads left on her skin. A loud grinding of wood yanked her attention back to the door, sending a chill through her veins. Robin had just set a what looked like a tree log cut in half across the door on two unevenly set hooks. "What the hell are you two doing out here, really?"


"Just minding our own business, I guess," Robin said while turning several smaller locks into place. Half-way through one, she gave out a sharp gasp, bracing both hands against the door as violent shudders jostled her tail wildly about. "L-looks like it's a bit too late to, aah, offer you some coffee. Heh."


"No, seriously, what the actual fuck?" Riley backed away, unsure of the things her own eyes were processing. It seemed like Robin's body gave a hard pulse that left her already pronounced muscles stretching out their clothes to the limit. She could see every ridge of the fennecs back poking through the cheap cotton, leading to a round fuzzy backside that also got significantly bigger. Plump cheeks spilled over the hem of some uncomfortable looking pants.


"We're, mh, werewolves, silly," Vivian said, sounding strained and a bit slurred herself. When Riley glanced over, the curvy wolf had set aside a plate of cooked steaks. It was a struggle to keep her hands steady while turning off the gas grill, but she managed before mimicking Robin's shuddering. "Guess we can...can, ah, nibble on cold meat later."


"You both are nuts." Riley backed away from the pair of anthro women, watching their tense spasms and moans become stronger. The windows looked too small to squeeze her thick frame through, and Robin's increasing bulk made it hard to even see the door, much less do anything about its lock.


"What did you think we were doing here?" Vivian gave off a course laugh with her heavy breaths. Sapphire eyes sparkled as she gazed out the window, hands constantly clenching into fists and uncurling with larger, thicker digits. Once draping clothes lost their slack even faster than Robin's. Sleeves drew in tight around bloating biceps while pant legs lifted like curtains around swelling calves.


Riley swallowed the hard lump in her throat, letting out a squeal when her backside bumped into the cabin wall. "W-well, I figured the best case scenario you were moonshiners."


"Mmh? N-not a bad idea," Robin mumbled before another rush of changes forced her to lower onto all fours. An arching of her spine caused her t-shirt to explode along bulking back muscles, setting free a pair of creamy medicine ball breasts.


As impressive as Riley found such mammaries, it was Robin's backside that truly captivated her. Both butt and legs were becoming the biggest part of the fennec, rising into the air while their swelling fat and muscle slid jeans off into a pool around her ankles. Ankles that popped into a high arch, putting weight on toes that doubled, then tripled in size. They hardly resembled the legs of a person anymore, being pushed slowly back while Robin's lower half appeared to be growing unusually longer.


Light thumping turned the human's attention back to Vivian. In that few seconds of inattention, the wolf had bulked enough to rival her changing friend. She walked toward Riley in a clumsy gait, no doubt to the result of her feet taking on a matching digitigrade stance. Each heavy fall of paws towards Riley seemed to add more to her height, a gap between shirt and pants hem widened to show off a rigid wall of black furry abs. Granted, they looked more like a sports bra and shorts straining tight around respective boobs and hips that were beyond mortal comprehension.


"Fuck this!" Riley had no idea where she found a rush of courage with a wolf built like a tank looming over her, but she was not set to be a late-night snack. Her athletic body burst into action with a hard jump off the wall, hoping to trip around Vivian's excessive girth to get at a far window before the pairs changes could finish.


Too bad plans work out better in one's head than in practice. Riley got five steps around Vivian when a heavyweight slammed her to the floor from behind.


"You shouldn't try running either," Robin's voice growled from about Riley. "Instincts are hard enough without being baited into a chase."


Riley managed to twist enough under the fennecs pressure to see she was being pinned down by a paw bigger than a lion's. Another animal leg rested beside her shoulder, lightly racking the floor with its sharp black claws. It took a second to realize these were not Robin's hands, those were being used to render her breasts free of the cheap t-shirt. Everything from the fennec's hips had changed drastically, gaining four massive animal paws with a thick barrel between them like a feral animal. A rich, fluffy tail swept the floor as her plump quadruped backside rested on its haunches.


"Oh my god, you guys really are monsters!"


"Wow! Rude!" Vivian said but sounded more amused than offended between grunts. The wolf was also starting to appear oddly stretched around the waist, looking slightly taller while she tried to remain standing on shifting legs. Little nubs grew up a few inches below her ribcage, lengthening out into proper forepaws while fresh joints and muscles formed. A soft snap rang through the cabin, finally forcing Vivian to take the same four-legged stance with an animal-like lower body. "We prefer to be called wolf-taurs, thank you very much."


"Sheesh! And we're even trying to be nice about this too." Robin shook her head with a mock chuckle. She rose onto her hind feet, using claws to slice through Riley's shirt as she stepped away.


"Gaah!" Riley squeal from the flash of pain that jolted through her being. A bit of wet coldness tickled at her now naked back were small drops of crimson seeped through the rips Robin had dug in. "The hell was that for...h-hey! Stop!"


"Trust us," Robin said, smugly watching Vivian use her forepaws to tear off Riley's shorts. Several more light cuts decorated the human's muscular legs in fresh blood. Being in an airtight cabin drove the werewolves wild at the scent. "You won't need those in a few minutes."


"Ugh! Speaking of which," Vivian trailed off looking back at her now feral behind. The idea of changing in extra-large clothes had backfired, and now the stubborn material was hugging her uncomfortably, especially around a gently forming bulge between her thighs. "Could you...um…"


"Pffft! Told you that wouldn't work." Robin giggled as she padded around Riley's sprawled body to get behind her fellow taur. Thankfully there was still enough space to tug the denim off around her thighs. Once Vivian gave the useless garments a kick free, Robin could not resist slipping a giant hand across her friend's feminine nethers.


"Grwar!" Vivian's looked back, unable to keep her toothy grin suppressed as Robin gently fingered the tender fur of a sack hanging in front of her slit. "Cheap shot, Robin! We haven't even broken in the new girl yet."


"W-what are you...going to do to me?" Riley had managed to raise her naked body onto all fours shuddering from the heat her multiple scratches sent rippling across her body. The pain had surprisingly dulled, but now her head swam with a feverish haze that left her gulping for breath. Getting up did not seem like a good idea with two wolves the size of horses padding around her.


"I can give you a hint?" Robin said in a teasing growl as she stopped in front of Riley. Forepaws pressed forward into pillars against the human's waist, leaving a warm fuzzy underbelly pressing into their back.


Warm hot musk burned at Riley's slim nose. The red wolf taur made sure to keep the human weighed down to stare into her crotch as another change took place. Just in front of Robin's dripping clit came the ruffling of dense fur, as if things were moving underneath. A lot of slack skin built up until, with a hard shake of her hips, the whole thing fell down to dangle as a tender sack. From above, it opened another hole from which emerged the tapered tip of a rapidly swelling red muscle.


"Oh my god!" Riley cried out in alarm at the canine penis erecting before her. Attempts to instinctively recoil were halted by the hard pincer Robin's forepaws had on her waist. A glance at Vivian saw the other wolf-taur had her own full erection bobbing about with her movements.


"Aw, don't be shy," Robin teased, bucking her hips to so the growing canine member stamped Riley on the cheek, much to the human's disgust. "He doesn't bite, unlike us."


Riley tried again but had no hope of breaking out of the wolf-taur's mounting. They were both practically the size of horses, after all. She was also worried to admit that the increasing scent of male pheromones filling the cabin was not helping her glazed thoughts any. Every second she spent forced to watch the throbbing Robin phallus dance inches from her face, the less disgusting it appeared.


"Go on and say hi, at least?" Vivian giggled in her journey around to Robin's backside. Both werewolves were rather pleased to see the minor injuries they had inflicted were healing under a coat of grey hairs. Lowering her belly to the floor, she was all too happy to drive her snout into the humans snatch, finding it pretty moist.


An adorable yelp echoed off the wooden walls making both wolf-taur's chuckle. Riley's panting grew heavier with every stab Vivan's tongue made at her exposed pussy. Hands clenched hard against the floorboards, peeling back flakes of wood with the increasing strength of her growing black nails. Without even realizing it, one hand shot up to grip Robin's thick girth, guiding it's pointed head directly into her drooling mouth.


"Ah, haa!" Robin gave a hard shudder, her feral butt jiggling from the rapid waves of pleasure as Riley sucked her off. "T-that got her going, all right. Aah! W-watch the fangs, girl."


"They always need a little push," Vivian smirked unseen with Riley's own butt in her face. The werewolf loved feeling their backside swell into her hands. Her long red tongue lavished Riley's clit while claws gently racked the fine pelt of grey fur spreading across her cheeks. "Yip!"


Riley gave a hard shudder feeling every muscle in her body flex at once. She was way too enraptured by the hunk of salami Robin offered to notice her body pulsing.


Robin and Vivian sure noticed when their new friend began growing. Well exercised muscles pulsed in rapid growths, doing in minutes what Riley needed years of weight lifting to obtain. Robin had to adjust her own stance to accommodate the growing mass between her front legs. She probably should have gotten off Riley's back when it began to broaden with harsh shoulder pops. However, the changing human's ability to give head was uncanny. Robin could not help stroking the wide curve of her massive breasts, rolling head back in long feral growls from the pleasure seizing her pelvis.


Vivian was not so fortunate when a thick tail busted out above her delicious snack of Riley butt, giving her a muzzle full of fur to choke on. Gagging, she staggered back onto her paws frantically trying to brush loose fibers from her tongue.


"Oh, shut up!" Vivian snapped to a laughing Robin. Looking down, the other werewolf beamed at the fine set of enlarged wolf paws Riley's feet had swollen into. They were nowhere near as big as hers, but that juicy ass sticking out from between Robin's front legs seemed to beckon her with its rapid bouncing. The fluffy tail on top of it was waging faster than a flag in a hurricane.


"Hey!" Robin barked when Vivian moved into a mounting position atop of Riley. Their bulky taur frames quickly put them at odds, even with Riley becoming a much bigger prize for them to share underneath. "Who said you get to have her?"


"You did when you shoved your cock into her face." Vivian gave Robin a raspberry, shifting her feral hips until certain that was the right whole her manhood was poking into.


"No. I was just teasing her, it doesn't count if she grabbed my, mmmppphhh!?"


Any protests Robin wanted to make were cut short by Vivian leaning in to give them a kiss. Their enlarged breasts squished together as front paws became intertwined, Robin quickly melting into the embrace as their hands roamed across each other's fur.


Turns out a pair of wolf-taurs could be very heavy. Then again, Riley's muscles had enhanced so much under the imposing lycanthropy that she barely noticed their strain. Heck, she could almost be comparable to Robin's amazing guns, right down to the beachball breasts scraping the floor, if she cared about that at the moment. The budding werewolf was more delighted to feel her slit get pierced by Vivian's throbbing rod, unaware of the sheath rising up under the loose folds of skin between her own legs.


"Grrrrr!" Robin recoiled from her embraced with Vivian, hands clenching tight onto the black wolf's thick biceps. It took a second for her friend to figure it out, but Riley could already tell with the way her cock was tensing up between her lips what was to come. Robin's whole body grew tense as she barked in sharp needy breaths. It lasted almost a full minute before the flood gates broke, and she reeled her head back in an orgasmic howl.


"Bull eyes," Riley sang smugly even as her face became basted in several shots of wolf cum. She did her best to lick up every bit she could, which got progressively easier with her face stretching out into a proper canine snout. Pointed ears tipped in the grey fur flicked out from under her messy blond hair as she looked back at Vivian's hips smacked against her ass. "Shall we go for two now?"


"Oooohhhh...I like her…" Robin chuckled, going limp in Vivian's arms with the waning of her orgasm.


Vivian did not get a chance to respond unless a surprised yip counted. The fresh wolf girl under her had rocked forward, driving most of her cock out before plunging it back in with a slam against her feral legs.


The cabin quickly filled with pleasured moans once more as Riley fell into a grinding pace against Vivian's meat. With the weight of a tired Robin pressed into her, the wolf-taur realized she was at this clever bitches mercy. Luckily she could make due squishing her friend's mammaries in between kisses that Robin soon got enough wind back to reciprocate.


Riley could not believe the power now at her disposal, grinding against Vivian for every inch the veteran werewolf had. Now she really understand the drive of natural instincts. Everything felt pleasurably amplified; the smells, the sounds, the urge to just crush a rock with her bare hands. It was hard to tell exactly how big she got, but the horse-sized taurs piled onto her back sure did not feel that imposing anymore. Not with the way Robin began to whimper when Riley saw fit to give their spent knot a tongue cleaning.


"Uuuummph! Oh, god!" Vivian growled, curling front paws around Riley's solid abs. The wolf-taur was bucking her hips, trying to meet Riley's in loud smacks.


It was clear why she felt a sudden burst of enthusiasm, as Riley could feel the wide girth of a knot struggling to squeeze past her taut lips when their hips met. She tried to reach back in hopes to help guide it in, only to grab hold of something she did not expect; her own throbbing wolf cock.


"Aw, fuck!?" Riley had to struggle to look around her dangling breasts and bulging muscles, but sure enough, she had grown a phallus just like the wolf-taurs. Vivian either did not notice or care about her current mate's bewilderment and continued pounding into Riley's fat butt. The constant grinding into her dripping pussy also massaged a new organ Riley could not recognize. Still, it sure helped make her knot swell fast. Curiously her meaty fingers curled around the tender shaft to give it a gentle stroke with their soft pads. "Aw, fuuuuuuck!"


Riley almost toppled herself over, trying to jerk off while getting ridden by Vivian at the same time. Somehow her one free hand managed to handle all the stress. There came a sudden pressure, and Riley felt herself give, welcoming Vivian's knot with a wet pop. The extra girth stretched in just the right way to climax. Riley's whole body shuddered in several hard spasms. Her snout howled into the underside of Robin's taur belly while her cock painted the floor with cum for the first time.


Vivian was not too far behind, groaning into Robin's face feeling warm flesh milk at her cock in hard contractions. She was all too happy to unleash her load into their newest werewolf, all three joining in a howl of harmonious unity for their respective satisfaction.


"She's...fantastic!" Vivian declared, her plump breasts accidentally smacking Robin with each heavy breath.


"No kidding," Robin said, taking a step back so they could admire the werewolf under them. "Shame she didn't become a taur, though. That would have been really fun."


Riley, for her part, was practically out cold. Between the stress of her first change, getting banged, and experiencing two kinds of orgasms at once, she was content to lay on the floor matted in semen from Robin and herself. Thoughts were an incoherent stew between her fuzzy wolf ears, she would still recognize the words her fellow werewolves were barking later.


"Think she'll want to hang with us again next month?" Vivian asked, hopefully.
