Thirteen years of customer service had a way of sucking the joy out of the holiday season. The realization that putting your heart and soul into work that was never going to matter to corporations was something soul-crushing. That and they cared more about appeasing the stress-inducing customers finding any excuse to lodge complaints. Nothing like getting free shit if it only destroyed a man's job.

Chris had to pay for his own Santa suit even. An amazingly expensive purchase the black-haired man slowly regretted as he trudged up the steps to his apartment. The last thing he felt while wearing the signature red and white was jolly. Hell, he had half a mind to go back to that Wal-Smart with a bat to see how much he could smash before security interfered.

Avoiding paying a bail won out given that January's rent was going to be stressful already. There were enough wrongful accusations dished out at Chris' expense, no need to have an actual crime added to his Christmas festivities. He continued to mutter angry curses to those stupid parents regardless as trembling hands struggled to get the front door open.

"Rough day at work sweetie?"

Chris had barely gotten inside and resecured his door before an angelic voice rang out through his studio. The fact it was clearly relaxed and female was probably the only thing that kept him from bolting back out into the freezing night. A quick flick of the light switch illuminated things enough for him to discover there was indeed a feminine figure spread across his bed.

"Who the hell are you?" Chris could not keep his voice from shaking, especially when his eyes rocked back and forth to better exam his visitors form. "What are you?"

"Wow, rude!" The figure laughed unphased by Chris's response. She casually closed the manga she had been reading from his shelf before moving to stand up on cloven hoofs. "I'm a reindeer, you dork. Cupid to be precise."

"Um…" Chris's eyes once again swept down and up across Cupid's humanoid form. It was a body better than a lot of model's he had seen encased in a Santa-themed skirt and tank top. Yet she was covered in brown and white spotted fur. Aside from hooves for feet, she also had a bushy little tail and an adorable little muzzle. There were even small antlers atop her head between erect twitching ears. "...okay?"

It was one of those hard-to-decide moments when it came to Chris' mind. That inhuman face smiling at him was way too expressive to be fake, which made him very curious. That also made her a general definition of a monster by most human logic. Granted, she had yet to do anything to indicate unpleasantries, much less a threat.

"Would you like to sit down, silly?" Cupid motioned to his couch giggling in a bubbly way that melted much of Chris' apprehension.

Having an interrogation at the doorstep was fairly uncomfortable anyway. Without taking eyes off this deer-human, Chris trudged the short distance over to plop lazily into one seat. Despite the situation, he had to avert his gaze long enough to remove the muddy black boots cramping his feet. When Chris looked up again, it was startling to see his guest sitting beside him. She had been so light he had not felt the cushions shifting to her weight.

It was harder not to jerk back when she leaned in to pat the knee of his red pants. "So, I'm happy to let you know you've been a really good boy this year. A shame some grumpy parents had to ruin your best night for it."

"Huh?" Chris snapped out of his daze to make eye contact. The deer's cleavage had fallen on display with her lean. If she noticed his ogling, it was not implied in her patient smile. "Oh, yeah. Don't even get me started on that. All I did was help a kid that slipped on the ice and they freak out I'm not 'in character.' Wearing the damn beard on a smoke break is stupid. Not my fault the bitch can't even notice when she's left her spawn alone. Excuse my language."

"Oh, by all means. We don't judge a little venting." Cupid squeezed his knee reassuringly. "And a week before today was those two idiots ghosting out on Christmas. Your Ho's were still pretty enthusiastic trying to handle all those stressed out, prudes. Being the only Santa for the month is no easy task."

"Yeah…" Chris stared at his hands, balling them into fists. "And I still got my ass chewed out with all the loading problems in the back rooms."

"Your boss was a bit of an idiot." Cupid gave a sage nod. "It was especially unfair the way he threatened you for making sure that poor customer got a turkey dinner for Thanksgiving after he was mugged. You should have told him you already paid for it."

"Employee discounts apparently void corporate sale goals." Chris sighed, but then blinked as another thought crossed his mind. Whipping his gaze back to Cupid he finally returned the deer's smile, however faint. "I'm sorry, I think I might have hit my head. Why is a cute deer person in my home?"

"Oh, I'm so sorry for wasting time." Cupid handed a cup of steaming hot chocolate to a surprised Chris. She paused to take a sip from her own mug before speaking. "Thanks for calling me cute though. No one ever cares about little Cupid. It's usually Rudolph or Blitzen or whatever those stupid movies focus on."

"Um…" Chris stared at the warm mug in his hands, to Cupid, and then back to the cup. It was not one from his home, making it the second thing to spontaneously find it's way inside.

After taking a test sip, he no longer cared to question it. The liquids sweet warmth quickly broadened his grin and made him sank back in his seat completely relaxed.

"So, yeah, you may have a tendency to get...snippy, as one naughty deli lady puts it, but I'm here to give you a present from the big man himself." Before Chris realized it, Cupid was pushing her chest into his shoulder to give him a quick peck on the cheek. "And also, perhaps, ask for a bit of help."

Chris scoffed in spite of the beauty pressed into him. Cupid's breath smelled delightfully of peppermint. "Santa sent you? What? Is he a super fat deer too? Oh no, I bet he's a polar bear tied with Coke, right?"

"Mm! Close; he is big and white, but Coke is a bit too interested in stock prices to split his brand fairly. We give them a couple hundred pounds of coal every year out of spite." Cupid coughed, swallowing a big drink of cocoa meekly. "But I'm digressing again. You interested in a more conventional kind of Santa job?"

"Yeah, why not?" Chris emptied his own mug pretty sure this was all some kind of delirium of stress. "As long as I'm not getting paid in coal it's got to be better than fast food, right?"

"Oh?" There was an awkward pause as Cupid starred expectedly at him. She had come prepared for a long line of questioning instead of blind acceptance. No point encouraging it, though. Christmas was wearing on fast. "It most certainly does, big guy. But we'll get to the details after we've unwrapped your present."

"What present?" Chris asked while Cupid plucked the mug from his hands. It promptly vanished into thin air as the deer's finger came back to press into Chris' nose.

"Beep!"

"What the fu...aahh!?" Chris leaned away from Cupid going cross-eyed as his nose scrunched up. A strong force like a sneeze built up behind his face, nearly making him cry in the vain fight to hold everything back. "Mmphh? Ggrraa? Huuugh!! O...oh, what?"

The force built up with expected ferocity to its typical apex. What caught Chris off guard was how it suddenly reversed direction at the last second. Instead of expelling out his mouth, the pressure washed down into the rest of his body. Force abated into a rather pleasant tingling sensation that made his hairs stand on end.

"What was that supposed to do?" He looked to Cupid, who just continued to smile in response. There was a special twinkle in the deer's eye that left him wondering. "H-huh? Nnn NNGGH!!? The hell!?"

Chris suddenly had a lot to worry about when the tingling crushed down on his pelvis. Thigh's instinctively pressed together as hands flew between them. Neither action did anything to help alleviate the sensations. It just made him aware of how things under the fluffy red velvet were pushing back.

"Aah haa!?" Chris' mouth dropped as his crotch unwittingly began to pitch a tent. Within seconds it rose beyond his usual size and started pinching inside his formally loose Santa pants. He reached for the belt but cast a quick glance back to Cupid. Given her excited tail wagging, there seemed little need to enact chivalry over an increasing discomfort. Chris almost tore off his belt buckle in frantic wiggling to slide pants and underwear down to his knees.

It went without saying that a dick popping out had been expected. The part that alarmed Chris was how unfamiliar and animalistic his phallus had become with a full erection. No wonder his member was cramping after it had swelled thicker than a baguette and towered nearly as long. Its head tapered off at the end practically glowing with a bright red skin all the way down to a slight bulge at the base. That was where the foreskin had pooled up into some kind of sheath. It and his balls nestled in a beautiful white fur that fanned out across his inner thighs.

"What the fuck did you do to me?" Chris found the view of his reformed canine dick suddenly blocked by the antlered skull of Cupid leaning in for a closer look of her own. "Uh...what are you doing?"

"Just helping you unwrap your present, silly boy." She gave him no time to respond, making a show of opening her mouth to drag her tongue across the tip of his erection. A few of her slender fingers gently wrapped around the knot at his base to give it a testing rub. Both worked perfectly in causing the man to fall back against his couch groaning with pleasure. "The change is a lot faster if you relax and enjoy it. And it's my job to make you as jolly as possible."

"C-change? I really don't get...o-oh!?" Chris felt his stomach clench and looked back down. Fur crept up from his crotch to blanket across his stomach and chest. He quickly opened up his coat to find his entire torso altering under its thick pelt. The gut he had as a result of a decade of skipping exercises melted away into a solid wall of abs while pecs swelled up into a robust and proud chest. A hand felt along the thick ruff, eliciting another moan. Although that could have been from Cupid enveloping her lips around his cock for a proper blow job.

The deer added gentle stroking of Chris' enlarged balls to her bobbing along with his shaft. Fur had made them especially sensitive if his constantly shifting hips were any indication. With each surge of pleasure Cupid's stimulating performance brought, the bigger and fluffier her newest recruit became.

Like how a fresh coat of shiny white hairs swarmed over Chris' expanding ass. The glutes underneath gave several hard flexes as they grew to overflow the cushion supporting them. Their energy flowed downwards into his thighs in a waterfall of mounting strength.

SHRRT! SHRRT!

Even when intended for an 'extra-large' man, Chris' thighs filled out his Santa pants in seconds. Their seams shredded in a symphony of tears allowing bushes of white fluff to bulge out.

"Ah fuck!" Chris rolled his head back in a prolonged growl. One hand absently rested upon Cupid head, giving her little scritches behind the ears. A token of reciprocation the deer seemed to enjoy with his first droplets of pre. He was too lost in pleasure to notice how his hands were puffing up in size, growing sharp white claws and soft paw pads to provide even better pets.

Though he did open a curious eye when his feet cringed at the changes cascading down his legs, his socks contorted and then puffed up around the toes like little round balloons. Claws easily shredded through the material as the foot itself elongated into proper canine paws. They gently settled back down with heels arched high, forcing Chris to walk on his meatball toes.

"Are you…" Chris coughed, surprised by the deeper tone of his voice. Even his neck was getting beefed up as fur slithered along it towards his head. Something about the feral rumble behind each word made things click together. "Are you making me a werewolf?"

"Mmmh! Surprised?" Cupid dislodged her face from Chris' cock to beam up at him. It was a great vantage point to watch large chunks of his hair bleach snow white. Most of it grew out into the beginnings of a rich mane down the man's back. "The boss is a hit with the kids and furry conventions. It's all about the whole 'big puppy' look that makes them light up with joy."

"Ohh… aah...t-that's kind of….really cool!" Chris' words fumbled when his tongue fell out of his mouth. The wet muscle suffered a slight growth that left it too long to hold inside a still-human face. "Shanta ish a weer woof?"

"That he is, big boy! Also, you're going to be a near matching image of him in a bit." Cupid surprised Chris by suddenly rolling off the couch. She took his enormous hands in hers to help get him up as well. It left him in awe to be looming over the cute deer by several feet. "What do you say about finishing your first change with a bang?"

There was little need for Cupid to explain as she sprung towards the bed while sliding out of her skirt. She emphasized her intent by bending over the mattress to present a raised tail to Chris. The wet fur around her aroused sex made it obvious she did not care for panties right before the smell of heat burned at Chris' surprisingly sensitive nose.

"Damn!" Chris tilted his head in admiration of the deer's amazing ass. After a second his canine cock twitched in need, making him give a goofy shrug. "Ah, what the hell."

Walking the few feet to his bed proved amazingly difficult on pawed feet. Chris waved his arms with each awkward step trying to keep balanced. It did not help that they were bulking up in another surge of raw power. By the time he was resting his hands on Cupid's hips, both sleeves had exploded off biceps the size of boulders.

"Mmh!" Cupid rested her chin in her arms folded atop the bed. Her booty bounced feeling the wet tip of Chris' member tracing its way along the folds of her sex. It was hard not to show tension waiting for the big moment, but getting to watch a transformation was always her favorite part of the season.

So it was a real surprise when she felt that throbbing wolf cock press against her lips only to withdraw.

"Uhm?" Cupid's ears perked as she waited a few seconds. When nothing further touched her naked rear, she glanced back to find Chris clumsily lowering onto all fours. His face vanished from view behind her fat hips, although pointed wolf ears soon poked out over the top. "W-what are you..o-oh! Haah! Aahh ngggh!!"

"Just repaying a favor," Chris said between long licks across the folds of Cupids pussy. His canine tongue relished her sweet taste as he grew used to moving it around, prodding her lips to tickle the sensitive pink insides.

"Aah! Aaah! Oh, fuuuuck!" Cupid panted and giggled sinking into the bedsheets and raising her rear into Chris' face. Her whole body shook with each stab of his tongue, finding it able to probe deeper as his face stretched out to become more canine. "I...mmhh...T-thank you forrr...ohgod...such a nice present. YEEK!"

Cupid's back arched as something cold and damp shoved its way against her tight anal ring. That had, of course, been Chris' nose being pushed out with his extending jawline. The skin's texture had already turned a rough black while nostrils could take in and single out every scent coming off the deer's fur.

"S-sorry!" Chris pulled back slightly unsure of what to do with his muzzle nearly formed.

Cupid gave a hint by shoving her butt back onto his face, and hard. "Fuck, take me now, you beast! I'm going to pop so harrrrrd!"

She certainly made a convincing case. Chris licked along the lips of his fresh wolf muzzle enjoying the remnants of Cupids taste before rising back onto his feet. Claws clamped more purposefully onto the deer's hips so he could steady his aim. His length of cock practically glowed like a Christmas light as it lined up with the well-worked deer's pussy.

"MMMHHH!!" Cupid bit her lip to stifle a moan as she took the whole length with one slick thrust. As expected it stretched her insides so tight that her eyes saw flashes of gold and silver decorations.

"Yip!" Chris felt a similar amount of joy until his knot slammed against the edge of Cupid's lips. Oh yeah, he had one of those now. At the same time, there came a strange popping sensation in his spine, promptly followed by a peculiar fluttering across his backside. Glancing back almost made him laugh to realize he had sprouted a very rich, fluffy, tail. It was already wagging vigorously to his happy pleasure high, while also making it easier to balance on two paws.

After a few more seconds of letting Cupid stretch to his girth, the werewolf leaned in across her back with a playful growl. The position was much better to rock his hips back and thrust in with a quickly building rhythm.

Thwp! Phom! Thwp! Phom! Thwp! Phom! Thwp! Phom!

"Aah! Aah! Aah!" Cupid breathed in cute little gasps. The bed groaned in protest as her body ground against it. Their motions quickly popped her tits out of the small top forcing them to rub violently against the fleece sheets. All she could do was clench a pillow riding the fire that wolf cock stoked inside her.

Chris' bed had been a hand-me-down, but at least it was a sturdy one. The steel frame seemed more than up to the task of holding his enormous frame while he performed his first act of Christmas joy. Seeing Cupid's top slide down to her stomach, he did not hesitate to reach around and grasp the deer's breasts in his large hands. The soft pads of his palms were even better than the fleece as he let the soft mounds to bounce against them.

Chris felt his balls slowly pulling tight under his cock, the start of tension rising deep inside him. Using the hugging embrace he had on Cupid, he tried to get a better position for the final plunge.

SCHLLLLOP! POP!

"Oof!?" Cupid's mouth fell open in a startled daze of euphoria. A strand of drool fell from her chin unnoticed. That one hard push had been just enough to stretch her already strained lips around the wolf's knot and envelope it into her warm embrace.

Trying to pull it back out proved to make things worse for Chris. The continued humpings only made the bulb balloon out further, locking the pair of anthro lovers together. Not to mention helping Cupid hit her plateau before she could fully grasp what just happened.

"Oooooohhhhh fuck!" Cupid buried her face in one of Chris' pillows to muffle the cries of her climax. Inner muscles clenched in hard contractions along the length of the wolf member embedded deep inside her. The puffy little tail stub above her trembling ass tickled Chris' belly button with its frantic wagging.

It seemed only polite to go for broke. Chris grasped onto Cupid tits with another flurry of hard, if slightly restrained, humps. The whole apartment seemed to tremble from the effects before his knot swelled one more time and finally released it's load into the woman under him.

"AaaaAAAWWOOOOO!!"

Unfortunately, he had no pillow for his muzzle, and the resulting howl would cause every pet in a two-mile radius to awaken their owners in a panicked frenzy. His member pulsed again and again sending out thick streams of cum that warmed Cupid in a very satisfying manner. So much so that it made the deer gasp when she felt her stomach and found it pushing into a small bulge thanks to the knot plugging it all inside.

It was almost a full minute before Chris finally came down from his climax. The bed gave a pained groan after taking a giant werewolf falling onto it but still managed to stay up. As usual for a good orgasm, the poor wolf almost went straight to sleep. It was only when he realized there was a rapid tapping against his chest that he remembered his company.

"Aw crap! I'm so sorry." He rose back up onto hands and knees, trying to move gently when his knot tugged at Cupids pussy too tightly.

"It...it's fine." Cupid looked over her shoulder a bit ruffled and all smiles. "You feel nice and warm both inside and out. I could stay under you all night."

"Heh, but I bet that's not the plan?" Chris ran a claw along the deer's back as she nodded. "So, what happens now?"

"Mmmh!" Cupid's body shook, getting a small orgasm from having her spine stroked. "What's say after that meat stick pops out we visit your old employers? I'm sure a few naughty ones are deserving your first bites."

"Seriously?" Chris laughed with a shake of his head. Even after all that this girl had ways to still catch him off guard. "So Santa is a werewolf that bites naughty boys and girls, huh? Dare I ask what it does to them?"

Cupid bounced her rear once against his knot and winked. "I'd tell you, but I think it's more fun not to ruin the surprise."
