“How about… him, in the Dracula costume?” Kiano uttered, that hyena pointing across the busy room towards a bull.
“Ehh… not really into bovines, you know that,” replied Jason, a red fox.  The two were a matching pair at the Halloween costume party; that shorter, and almost twinkish vulpine taking the roll of Little Red Riding Hood, while the stockier hyena decided to go as the grandmother from the story.  When he debuted that costume to a flabbergasted Jason, who had assumed Kiano would be taking the wolf, the hyena laughed loudly—claiming that if the fox was going to “dress opposite” than he might as well, too.
“Yeesh, picky, picky.  You better hurry up and pair up with someone, though, or you’ll just end up goin’ back home with me—and that kinda defeats the purpose of a swinger’s party, don’t you think?”  Even as he spoke, the hyena had cupped the fox’s ass, giving those pert cheeks a firm squeeze, lifting up that red skirt just slightly enough.  
“Ugh, stop it,” Jason grumbled back, rolling his eyes.  A hand pushed back and down at the one on his ass—but soon another smacked up against it from the other side, one that wasn’t the hyena’s.  
“Gyehehe, looks like someone else chose for you,” that grandmother-dressed hyena bark-laughed, slipping away into the crowd—probably to find a partner of his own… or to get another drink and watch Jason “flirt” with the new guy grabbin’ his ass.
The fox bristled a bit, and though his ears burned slightly at the hyena’s remarks, he turned to face his ‘molester’. Well, that other male’s chest, at very least.  The maned wolf before him was quite tall—a head and a half larger than the fox, despite having a frame that seemed to be no heavier than Jason’s own.  His costume seemed to be a doctor’s outfit of sorts—stethoscope hanging from neck, and a rather authentic lab-coat with some less-than-authentic bloodstains on the sleeves.  
“You’ve got a nice ass… what’s your name, or should I just call you Little Red?” the maned wolf uttered.  He had a smooth voice—even if those fingers didn’t leave the vulpine’s rear as he squeezed once more.  Jason was committed to his costume—he was even wearing a pair of crimson panties underneath that skirt, which conformed to the shame and curves of his hind snugly.  
“Jason.  Please,” the fox replied.  Little Red had been his nickname through middle-school—while he was still a runt of a fox, not that he had really grown out of that “runt” status by much, though.  “And you, Doctor…?”
“Doctor Frankenstein.  The one who created—“
“Frankenstein’s monster, yeah, I get it,” Jason interrupted.  “Where’d you get the lab coat?” 
“It’s mine—I’m a student at Hill Hospital,” the maned wolf—Dr. Frankenstein—replied.  Sure enough, on the lapel of that lab-coat was the hospital’s logo… and the canine’s real name, Kevin.  “Same with the scope, too—though I should’ve just brought a prop one.  These things are fuckin’ expensive,” he uttered.  
Kevin leaned in a little closer as he spoke, his taller body almost lurching over the fox’s own intimidatingly, despite the maned wolf’s thinness.  He exhaled a little breath over Jason’s ears and costume-hood, a toothy smile soon following, as he slipped his hand up from the vulpine’s rear and along the other’s back, just above tail.  He was quite a toucher, not that the fox minded too much.  Hell, it was almost expected at this particular brand of party.  
“Your place?” Jason asked after a brief moment of pause.  He still felt a little tense, glancing over his shoulder for the hyena he had entered in with, though that stocky fuck was casually chatting it up with a rabbit.  He still gave a wink when he caught Jason’s eyes with his own, at very least.  
“Eager? No need to rush things, there’s still plenty of booze left,” the maned wolf replied.  His other hand held a cup half-filled with the punch—the scent of vodka just barely hidden behind the fruit.  “But, hell, if you’re that ready to go, we can just slip off into one of the backrooms… that’s what they’re here for, aren’t they?” Kevin took a swig of that spiked punch—his Adam’s apple bobbing with each swallow as he finished his cup.  
Jason’s ears burned a little—he could hear Kiano’s raucous laughter even over the din of that party and background music.  It took him a moment to figure out why—his tail had flipped upwards once the maned wolf placed palm on his back, and he was flashin’ those panties to whoever cared to look.  Ears flushed redder—and now more than ever it seemed as if he wanted to leave.
“Fine, backroom it is,” the fox said, moving away from the maned wolf’s casual squeeze and dropping tail downwards.  He snatched up that hand with his own, pushing through a few costumed party-goers—a mummy and a ghost—both of them looking rather cheaply made out of toilet paper and a single sheet respectively.  
The party was hosted at one of the richer sections of town—a neighborhood where the houses had more rooms than sense—and once out of that main “living room” of sorts, a long, well-decorated hallway stretched along towards the far back of that house, several rooms lining each side.  Most of them had been closed and locked already, and what sounds that could be heard from within… moans, groans, and the wet smacking of sex.  
“You a moaner, too?” Kevin said—as they passed a door with a particularly vocal couple within.  His face seemed a little bit flushed under the fur—perhaps from dunking back that punch a little too fast—and he had a cocky smile upon his face, as if to say “because if you aren’t, I’ll make you one”.
“Get the right angle and I am,” the fox replied back, those noises seeming to spur him on a little more… or perhaps he was just loosening up now that he was free of the crowd.  They passed another door—almost going in before they spotted a lion inside, ramming a sheep balls-deep.  Perhaps another more adventurous coupling would join that pair, but neither Jason nor Kevin felt it in themselves to “intrude”.  
The next room was empty—curtains drawn open for a view of the lake behind that house.  It would’ve been a more magnificent view, had the clouds not decided to block the stars and moon above.  Jason made a move to take off his costume, only to have his hands blocked by the maned wolf’s own.
“No, no… keep it on a little while longer,” the canine said, a little bit of hunger in his eyes.  “It suits you well, y’know,” he said, pushing Jason backwards to the bed, almost tossing the poor fox onto his back.  
“More than you know,” Jason replied—a little smile split over his lips, his hands reaching down to keep his skirt from flipping up and exposing those sheath-bulged panties.  He wanted to squeeze his thighs shut, too, but Kevin had maneuvered himself right between those knees, keeping legs spread apart, as if he had read the vulpine’s mind. 
A hand brushed along Jason’s midriff, pushing up the cloak slightly, baring that red fox’s creamy tummy-fluff to the maned wolf.  The vulpine was thin for sure—that girlish figure only betrayed by the slight scent of masculinity coming from his fur, and the small bump upon that throat, which bobbed slightly as his stomach was half-tickled by the soft brushing of fingers through fuzz.  
“Fuck, you’re cute,” the maned wolf muttered—an almost dopey smile spreading across his face.  Damn, that punch was really kicking in now, it seemed.  With that cloak lifted up, both hands dropped down to the underside of that fox’s thighs, lifting them up towards Jason’s chest, taking skirt with it!
Jason flushed a little redder—not only from the compliment (not that he had any trouble getting those), but also from the positioning that maned wolf had put him in.  His ass was completely defenseless—save for the pair of panties currently wedging themselves up between cheeks, leaving little to the imagination as they snugged around sack and sheath alike, making that one bit of obvious masculinity pop out even further.  
Kevin let out a soft huff again, seeing the way that those cheeks framed red panties, the orange and white of fur just barely fluffing out from behind silken, girlish underwear.  A finger swiped along the cleft made by that wedging fabric, digit tracing from the underside of tail all the way to the bottom of sack—pausing just a half-second at the taut pucker hidden behind sleek silk.  
“I mean, fuck, really cute,” he repeated, practically licking across his own lips.  That perverted canine was staring right at the fox’s ass, and the dress-slacks he wore beneath his lab-coat were obviously tented with arousal.  He took a little inching step closer, before Jason spoke again.
“How about showin’ me what I’m getting’, hm? Before you bust a nut in your pants, just from gropin’ my ass,” the vulpine said.  Kevin may have taken offense, had he not been completely and utterly enraptured by the fox’s figure, and he quickly stripped of his lab-coat and underclothes, draping them over a chair.  When he had returned, the fox had hooked his fingers into those panties, tugging the fabric that rested against his taint and ass sideways, exposing that white fur and a taut pink pucker.  
“Holy shit…” the med-student muttered, his own shaft throbbing at full mast—a pleasant nine or so inches of canine masculinity.  Precum dribbled from the tip of it, unbidden, as he knelt down at the edge of the bed, one hand squeezing the backside of Jason’s thigh.  Lips pressed squarely against that ass so suddenly that even the fox was half-surprised, letting out a squeak as tongue flicked along tight pucker.  
“Nngh…!” Jason inhaled, his back arching a bit.  He could feel his arousal slowly slip free of that sheath, filling out those panties further, until that cockhead slid past the waistband and preseed drooled onto his upturned skirt.  It dampened the costume as each sweep of the maned wolf’s tongue brought about a new spark of pleasure through the vulpine’s body.  
Kevin’s eyes lidded shut, both hands squeezing the fox’s ass, spreading those cheeks a little wider.  It was hard to explain his sudden urge to French-kiss Jason’s ass beyond, well, it just looking too perfect to resist!  A soft, semi-salty taste of skin tingled upon his tastebuds as he slathered tongue along taint and pucker alike, pressing inwards for that fleshier flavor, and an almost richer musk from the vulpine’s silk-covered sack.  Spit and drool dribbled down his chin, his fur growing heavier with saliva before he finally pulled back from that rear, trails of fluid snapping from pucker to lips as he broke that connection.
“Haa… haa… fuck… I don’t know what came over me…” he huffed, his hands soon moving to hook at the waistband of those panties, and pull them clear off of Jason’s legs.  He wanted them as a souvenir, and took a deep, huffing inhale through those underwear, feeling his knees wobble just a slight bit from the rush that heady scent gave him.  “Nghh… why do you smell and taste so fuckin’ good,” he groaned, one hand dropping low to give his rigid malehood a quick squeeze and stroke—a knot already half-engorged at the base of his shaft.  
“A fox’s gotta keep his secrets, don’t you think?” Jason replied back—a coy smile upon his face.  A silvery light filtered into the room through that wide window, moon reflecting off the lake outside.  Seeing that maned wolf pathetically horny and huffing his panties only encouraged the vulpine further, stripping off out of skirt and cloak alike, until he was nude on the bed, illuminated by moonlight.  It made that orange and white fur seem almost silvery—and the fox’s blue eyes had an almost yellowish tint in the iris.  
Kevin fell atop of that stripped fox needily, sliding up between thighs, his nine inches pressing alongside a reddish six.  He couldn’t help but stare hungrily into that feminine face, leaning in for a kiss that he normally didn’t give.  Lips pressed against the maned wolf’s own, a tongue streaking into that canine’s maw and flicking along the backside of teeth.  A pair of arms wrapped around, squeezing Kevin’s back a little closer, with surprising strength, and the vulpine rolled hips upwards against that frotting length.   
A quiet growl left Jason’s lips, fed into the maned wolf’s own as he shifted to one side, and then rolled—flipping the taller male onto his back.  With their new position, Kevin opened his eyes again, meeting the fox’s yellowed-by-moonlight pair.  
“Hffhh… haa… gonna… ride me?” he said, breathlessly, feeling the weight on his hips grow heavier.  It was strange, the way the moonlight had cast its shadows on Jason’s face made it seem just a little more masculine, and his muzzle a bit blockier.  The fox bared his teeth in a smile.  “Hah… have you always… nnh… had such big teeth…?” Kevin muttered, starting to feel something slightly amiss… especially as he noticed how that six-incher that he had previously dwarfed was now drooling a good deal further up his belly than his own dick, despite those balls still touching together.  
“Oh,” Jason began—voice an octave deeper, not quite that falsetto from before.  “I’ll ride you for sure,” he rumbled.  His shoulders seemed broader too, as he leaned over the maned wolf.  Thin, feminine orange-furred arms had bulked into a buffer pair of silver, lacking that twinkish nature that had attracted the maned wolf in the first place.  That fox’s chest, too, which had started off looking more like a flat woman’s was packed with tighter muscle and a silver coat.  
“W-what… what… what…” Kevin stammered—starting to feel dwarfed by that fox, whose face certainly didn’t look foxish at all anymore, but that of a wolf’s.  
“Not what, were,” Jason growled in response.  His smooth, bushy tail lost its fluffiness in favor for a sleeker, shorter-furred coat of silver-gray, flicking doggishly from one side to the other.  “Werewolf, to be precise,” that former fox uttered, his yellowed eyes gleaming.  “You didn’t think I was just a stereotypical slut of a fox, now did you?” 
“Ba-ba-ba-,” Kevin babbled, his brain too fried and confused to actually form words.  He didn’t think werewolves were even real!  And now here he was, pinned down by one that seemed very horny… and he had called it cute!  Two thick, ripped thighs pushed his own aside as that werewolf took place between his legs.  “W-wait…!” he managed to squeak out, glancing down at that ruthlessly large dick of his partner.  Hot precum spattered from the tip of that massive thing—which had more than doubled in size from the fox’s former six.  Kevin had been pretty proud of his package, but in comparison to the werewolf’s it was like a pair verses a royal flush.  
“Wait? You were so eager to get started just a minute ago,” he said, baring his teeth in another smile—that toothy grin practically splitting from one end of muzzle to the other.  Another splurt of preseed gushed from that tapered tip, almost as thick as cum, glimmering in the moonlight upon that maned wolf’s belly-fur.   Jason shifted his hips backwards, dragging that cockhead from just below the poor wolf’s ribcage to belly-button and lower, taking his sweet time as he worked on getting that borderline absurd dick to line up with Kevin’s pucker.
“That’s not gonna fit at all!” the fearful maned wolf finally said, voice almost cracking.  He struggled a little more beneath the werewolf, but every part of Jason’s transformed body was like pushing against a solid rock wall—and it exhausted the maned wolf of his stamina.  “You’ll… you’ll split me in two!” he cried.  
Jason laughed, boomingly.  His eyes glinted a bit, dick pressing snug against that pucker, preseed slowly soaking into that hole, seeping deeper and deeper along that passage as he leaned forward.  Even just the tip of that prick was intimidatingly thick—like a thumb and a half in diameter!  His breath, hotly and humid, washed over the maned wolf’s face before he slid muzzle towards Kevin’s ear.  
“Oh, it’ll fit alright… don’t you worry your head off, you’ll love it,” he rumbled.  
There was a flash of pain and heat in Kevin’s neck as that werewolf bit down.  Teeth broke the skin, and something went in—though what it was, that med-student couldn’t tell.  All he knew was that it felt hot—like his entire body was in a sauna.  He arched his back, as if getting a little bit of air between himself and the bed would help—but instead it only pressed another inch of that werewolf’s monstrosity into his rear, stretching that ring further.  
“Aah!”  Kevin crossed his eyes.  Rather than the sharp twinge of pain he had expected, a rush of pleasure sparked up his spine, and that sweating heat swirled lower in his body.  Only two inches in and he could feel every pulse of precum spurting into his bowels, that maned-wolf hyperaware of the former fox’s masculinity dumping slickening fluid into his body.  As his eye-crossed vision returned, he tried to turn his head, only to feel the pinch of teeth against his neck again, and another pulse of pleasure streak along his back.  “Oooahhnn…!” he moaned. Another inch—no, two, had sank inside—stretching his rim beyond what he had thought possible.  His toes curled tight, balling up.
“You’re a moaner, huh?” the werewolf rumbled deeply, finally taking his lips off of that bitten neck.  A bit of crimson glinted on his teeth, the outline of those chompers bruising to a dark mark beneath the maned wolf’s fur.  Precum spilled out from Kevin’s shaft, puddling up into a complete mess on his belly as that “toxic” bite did its work—transforming the sensations of pain and stretched pressure into pleasure.   
“Ghaah… ohh… hhaahhh…!” Kevin panted—the maned wolf hardly able to speak, let alone comprehend what that werewolf was saying.  Nerves were sparking in his hind and brain, eyes about to roll up once more as he splayed his legs apart a little further, in a submissive gesture he had never made before.  “Tuh… take… hhhh… fuhhh… fuck me…!” he managed to huff out.  How could he think with that brutal dick squishing inside, practically pulverizing his prostate once another few inches had intruded into his rear?
Consenting or not, that werewolf wasn’t about to stop any time soon.  The maned wolf’s legs were grasped by the ankles and pinned up to his shoulders in an exaggerated ‘v’, while hips pressed inwardly to the canine’s rear.  Somehow that pinkish pucker strained and stretched to contain that entire girth, each inch that sank inside sending more howls and moans of pleasure from Kevin’s lips.   As soon as Jason’s knot had kissed up against that pucker, a drooling spurt of cum leaked from that maned wolf’s cocktip, spilling out slowly from that compressed prostate.  The only difference between it and his precum was the cloudy-white coloration of seed. 
The maned wolf’s toes curled again as he hit orgasm, mouth hanging slackly—except for when he squeaked and groaned in ecstatic pleasure, feeling those inner walls shift around to accommodate the werewolf’s large size.  Post-orgasm he felt a brief moment of lucidity, gazing down at the obvious bulge of dick in his belly—almost in horror—before it shifted again, and that refractory period was forgotten by his body.  
Inch after inch of dick slid outwards as Jason pulled back for the first, formal thrust into his evening cock-sock.  He could feel those walls clinging to that slick shaft, as if begging for it to remain inside, and hear the soft whimper of that maned wolf beneath him as another tingle of growing orgasm coiled in his loins.  He paused at the middle of his length… a “mere” seven inches still remaining within that canine, before reversing course and cramming his knot hard against that pucker once more, practically sucker-punching the underside of Kevin’s diaphragm.  
“Kehhaahhh!” the maned wolf yelped, and, oops, another orgasm oozed out from dick.  The poor doctor-to-be’s balls would be aching by the time Jason finished, should this pace keep up!  He could only hope that the werewolf was quick to tie and shoot… but his last hope of a cute fox to fuck had ended up poorly.  
Another gut-punching slam of hips against ass made Kevin howl out.  He had lost track of the number already, but was certain that it was close to fifty.  That werewolf was fucking him slowly, practically savoring every squeal, howl, whimper and whine that he made—balls long since emptied of their contents, and the only thing sputtering out from them was a weak stream of clear, saline precum.  
Again, there was that deep, internal suction as that shaft slid backwards from his depths, pulling inch after inch after inch of malehood from walls that had long since been adjusted to the size and shape of his werewolf stud.  This time his belly didn’t divot inwardly from the removal, Jason’s constant pre-dribbling having filled that particular void… though each thrust seemed to slosh nearer and nearer the maned wolf’s belly.  
Kevin’s breath slowed, feeling that pull-back stop.  It was the same every time—the werewolf paused for just a brief moment, barely, just barely, adjusted angle, and then crammed inside, drawing out an orgasm from the maned wolf beneath.  He had almost long since forgotten what he was waiting for—each single thrust seemed to take minutes—minutes that dragged out into half-hours as Kevin rode the throws of orgasm after orgasm.  That cock lurched, and the maned wolf let out a breath, ending just as that knot smacked against his rear, and his body arched up once more in a futile effort to expend its non-existent seed.
“Hgghhkk!” he vocalized—long forgetting words and syllables at this point… but that slightly changed angle was new enough to pop in a few inches deeper, and the maned wolf let out a howl of pleasure despite his emptied lungs.  It was all in.  Hands, which had laid exhaustedly palm-up on the bed suddenly clenched into fists as he felt that first, thick spurt of spunk erupt into him.  It was drastically different from that precum that had soaked and flooded his inner walls long earlier: heavy, hot, and thick as tar.  Another gush spilled deep into his bowels and body, and Kevin’s eyes dipped down at his belly, seeing it bump outwards almost an entire half-inch.  The third, and he could feel that hot semen spilling further up into his belly.  The maned wolf tried, and failed, to bring his hands up to that bumping stomach, but all his stamina had been drained.  Another throb, and the poor canid hit a second (dry) orgasm from that single thrust, his eyes squeezing shut and throat tensing in a yowl of pleasure.  Again.  Again.  Again.  
Kevin’s jaw slackened as he felt each pulse of cum gush from those heavy, lupine balls churning against his rear—cum flooding his body, bloating out his belly and splattering the back of his teeth.  Fuck, that werewolf’s potency was absurd, even if that orgasm was a few hours in the making!  Another throb, and more of that semen drooled out of Kevin’s lips, the maned wolf weakly coughing up that cum, tasting the rich musk of his partner.  
Two broad paws swept down the maned wolf’s sides—curving out for that plump, almost pregnant-looking belly.  Jason seemed quite pleased with his “pick” for the night, at very least—his nuts emptying away, a good portion of that batter somehow remaining within Kevin’s bowels… though it’d be a different story for when he pulled out.  He shifted just a slight bit, feeling (and hearing) the bed creak beneath him as he slowly, slowly pulled upon that knotted shaft, feeling rim clench meekly against his bulb, but not nearly strong enough to overpower the werewolf’s hip flexors.  As that knot popped free, it sounded almost like a champagne bottle being opened, cum splooging out of that de-knotted pucker—slowed only a slight bit by that thick shaft still remaining.  
Inch after inch after inch slid out of the maned wolf’s ass—more semen slopping free of that rear as Jason pulled himself completely free, and that ruby-red wolfhood twitched in the air, covered in a lacquer of warm cum.  The maned wolf below could only pant loosely and squeeze that pucker weakly—the muscles in it burnt out from their ordeal, leaving him gaped and cum-drooling, soaking semen onto the bed below.  
“Uuhhnn…” Kevin groaned, unable to say much more than that as he felt that utter void in his bowels—the werewolfian heat that he had grown so accustomed to vanishing, along with that gooey filling.  Even his legs were too tired to return down from his shoulders, leaving him a ruined, sticky mess—dazed and confused.  He could taste that seed in his mouth, feel dribbles of it rolling along muzzle and cheek, even after swallowing.  
“See you next Halloween, big guy,” the former-fox rumbled—still in that canine form.  His dick hung between thighs heavily, shamelessly swaying as he gathered his costume and left the room—that door staying open for whomever felt like using the maned wolf next.  Of course, they wouldn’t be getting much out of him.
