At the end of the year 2019, rumours of a virus were spreading around the world. The only symptom at the time was slightly increased hair-growth, so its effects were hardly alarming. The cause for concern was how easily it spread; airborne, touch, fluids, and every other transferrable medium. Testing found that the virus was present in a majority of the population in every single country. A single, deadly mutation in the virus could spell the end of the human race, thus a pandemic was called and quarantine enacted.

Just a few months into 2020, the virus mutated, but not in a way anybody expected. Scientists reported a change in infected DNA, drastic change, enough to physically deform the host into something nonhuman. It was suspected and later confirmed that the virus mingled with local wildlife then transferred elements of their DNA over to humans. After infection, there was an incubation time of about a month- hence why nobody had detected the virus until it was too late- before the host's body began to change. The first few days started with the skin growing hairier, scalier, or whatever other skin surface their triggering animal had, as well as claws, teeth, and horn growth. The next couple days warped, dissolved, and added bones to give most victims tails and digitigrade legs. By the end of the week an infected individual would turn into an anthropomorphic animal, usually based on their local wildlife.

There were a few exceptions as the virus mutated wildly; some transformed into hybrids- a mix of multiple animal DNA- while others became something nonhuman and nonanimal, at least of this world. Many of these rare mutations resulted in new species, such as creatures that existed only in the imagination, though in rare cases the virus would tragically warp a victim into some misshapen form incapable of surviving without extreme medical attention. Other than that, the virus was shockingly non-fatal. Infected individuals gained some of the feral instincts of their animal counterparts, but were otherwise in complete control of their faculties.

The early days of the pandemic held great fear that 2020 would mark the end of the human race, and rightly so. Once vast amounts of humans started transforming into 'furries', there were mixed opinions. Most saw the change as little more than inconvenience, and continued their lives as altered beings. A surprising amount of people embraced the change, claiming they felt more comfortable in their new bodies. Later interviews and research would reveal that the psyche had a significant effect on the virus too; those who felt strong kinship with particular animals were almost guaranteed to direct their transformation into their preferred form, allowing infected individuals to become anthropomorphic versions of animals that lived nowhere near them, or creatures that didn't exist such as dragons. For others, the virus was not a blessing but a curse, which led many to despair or a permanent 'solution'.

A combined global effort worked tirelessly to find a vaccine or even a cure for the virus, dubbed “Corvid 19" after the first victim transformed into an anthro crow. Hope dwindled as more and more people became infected, leaving humans as an endangered species on Earth. Scientists lost motivation for finding a solution, and instead shifted to researching ways for returning society to 'normal' in the wake of Corvid 19. A few continued to study for a way to reverse the virus, funded by suspiciously wealthy humans trapped in quarantine bunkers.

Humanity wouldn't go extinct, there were far too many millionaires and billionaires for that. At the first sign of danger, they scurried into their holes like rats, living in luxury thanks to an enormous waste of resources. In a way, Corvid 19 provided another blessing by forcing a portion of these wealthy humans underground where they could be safely ignored. They would try to remotely direct their underlings from safety, but their influence was greatly dampened on the society that continued without them just fine.

A portion of the general population remained in isolation too, quarantining themselves at home and getting delivered supplies by sterilised drones. But all it took was one slip up, one improperly disinfected delivery, and another human was infected. Some radicals even infected humans on purpose, spouting nonsense about some “New World Order". These groups were constantly put down, and the decision to be infected or remain human encouraged. As the furless humans became more of a rarity, more care was given into preserving them. And as always, there was profit to be made.

Human shut-ins would stream themselves online, becoming hugely popular for those that longed for their old lives back. Half of the skin care companies shifted to fur care, every single clothing business had a nightmare of redesigning outfits for the unending new forms of their customers, and new business opportunities popped up in light of new natural strengths (and weaknesses) of the population. Deliveries could be made swiftly by avians, custom outfitters were in high demand, and deep-sea exploration became a whole new world of possibility.

The first several months of 2020 would still be a nightmare as a significant portion of population could no longer use tools designed for human hands, get into their cars, or countless other inconveniences that would impact society at large. The world slowed to a crawl as technology struggled to accommodate such a dramatic change, but it survived. This would not be the end of humanity, even if a majority of them were replaced by 'furries'. For the common folk, life went on, if a little stranger.

“So that's how the current global situation is, and things are likely to continue drastically changing for a while longer" said the goat at the front of the classroom, reading from a print-out to those still listening.

At just a month after the first reported transformation, things were still developing as life continued. Society had paused for a couple weeks in the hopes of a solution, but when it became abundantly clear that the virus was here to stay everyone went back outside to keep the lights on. The younger generation growing up in the global crisis still needed to be educated, and thus Ryder was back at high school listening to Mr Jenkins explain to his class the nature of the virus, being the high school's best science teacher.

The old goat went into the specifics, highlighting how Corvid 19 interacted with human DNA and the mysteries of willpower that seemed to influence the subsequent transformation. Mr Jenkins himself was known to have a pet goat, making it no surprise that the old man transformed into a patchy black and white copy complete with stubby horns and goatee. Ryder's classmates were all common cases, mostly transformed by their house pets or wild animals, with one notable exception being Josh; he had shifted into an anthropomorphic red dragon. Everybody fawned over him, and he explained with Mr Jenkins' help that he'd always held a deep love for dragons.

In Ryder's class of twenty-eight, three-quarters of them were some kind of animal while the rest, himself included, were still human. For now. There were no doubts that they were infected, and cases for natural immunity were so rare that they were in the double digits across over seven billion people. It was only a matter of time until those several humans lost their humanity, with some already showing symptoms of fur and claws. Ryder had no idea what he'd be. The young man didn't hold particular love for any specific creature, at least one he could think of, including his current form. It was impossible to tell which variant of the microscopic virus infected him, so he tried not to worry about it.

It would be at least a month, since this was his first day back in school. Ryder's family made the decision to hold on and isolate longer than the rest, but recently resigned to rejoining society and accept the inconveniences that would surely be far more tolerable than quarantine for the rest of their lives. And so, Ryder was back at school trying to catch up on the weeks he had missed amongst an ocean of animals, especially since it was his last year of high school – the most important year. As Mr Jenkins was analysing one of the humans with symptoms to guess what they'd become, the bell rang. School was over for the day.

“I know things are crazy these days, but your test is still next week!" Mr Jenkins called out to his class, “Those of you who have been away, I suggest you find some friends you can catch up on study with." The goat's strange horizontal-slitted pupils passed over the humans, landing on Ryder as he had been away the longest.

The eighteen-year-old shrunk, knowing he had quite a lot of science homework to do; instead of studying at home, he'd treated the quarantine like a surprise holiday and played a lot of videogames he hadn't had time for before. Ryder packed his things into his satchel bag and glanced around the room for potential prospects; he had plenty of friends he could ask to study with, but this was a good opportunity to get to know an anthro better, specifically one of the dogs- none of his friends were canines.

He'd always been fascinated by canines, not in the sense that he'd want to be one, but from an observing perspective. There were a few that caught his interest: a tall doberman, a friendly-looking golden retriever, some sort of mutt breed he couldn't name, and- glancing at the back corner, a wolf he was surprised he'd missed until now, given how big they were. A patterned brown wolf with a tan underbelly, who Ryder was sure was sitting in the seat of the class nerd, a lean and introverted kid whose name would not be remembered. If this was the same person, they were now a handsome wolf man with kind, green eyes and powerful physique. Ryder hesitated to call him attractive, since it was still a grey area being attracted to animalistic features, at least for him.

The wolf packed his things into a small backpack, which he then slung over one arm as it was clear the old bag would no longer fit comfortably across his broad back. Following the behaviour of the nerd he'd seen before, the anthro canine headed around the perimeter of the classroom and out the door without talking to anyone. Ryder followed after him.

He seemed like the perfect target: an interesting canine, nerdy enough to be good for studying with, and perhaps easy to befriend. Ryder caught up with long strides then matched his pace as he walked down the hall towards the front of the school. The wolf eyed him curiously, noting the human's presence but not stopping.

“Hey, you doing anything today?" Ryder asked, looking up at the taller teenager.

“No.." he replied with a look that meant I was going to relax all evening, but you have my curiosity- a look Ryder recognised well.

“It's my first day back, so I was hoping to do some study. I'm Ryder"

“I'm Duke."

“Sooo, would you be willing to help..?"

The wolf stopped in his tracks to think. He looked pensive, to Ryder, as if weighing up the freedom of an afternoon with whatever he had to offer.

“I guess.. But don't you have other friends for that?"

He needed to up the reward.

“Yeah, buts it like- I've never seen a wolf before! You're really interesting" Ryder said with a smile. It was simple flattery, but also the truth, ulterior motives included. He noticed the wolf's tail wag cutely. Success.

“Uhhm, sure! Where do you wanna study?"

The human smiled warmly, hiding his devious intentions, “Your house or mine"

“My family is going out for a thing tonight, so we should get a bit of quiet in the evening. Want to follow me home?"

“Sure!" he beamed. This is going perfectly, Ryder thought.

The pair walked out of the school grounds, Duke leading him a few streets away to his home. The two walked and talked, finding they had more in common than they thought; they loved video games and canines. Duke didn't play the same games that Ryder did, but the experience was transferrable enough that they could talk for hours. It was, however, a short walk to Duke's house – short enough that Ryder was envious of how close he lived. The brown dog fished a key out of his wallet and opened the way for them.

Ryder expected a family of wolves. Instead, a grey-striped feline woman welcomed them. The mystery was solved when a similarly grey-striped housecat rounded the corner to investigate. The small pet was happy to sniff and rub itself on Ryder's leg, until Duke approached. He noticed disappointment on the canine's features when the family pet scampered away from him. Ryder removed his shoes and watched in fascination as Duke did the same with his standard 'canine footwear'. It was a crude design, with lots of straps. He supposed the eggheads were still working on it.

The two headed upstairs to Duke's room, which was cleaner than expected. It was a little messy, as most boy's rooms were, but his was a sort of organised messy. Something else immediately noticeable was the smell- musky was the only appropriate word. Ryder had noticed Duke's faint scent as they walked, and now that aroma was all he could smell in this room. It was earthy and masculine, tinted with something that made Ryder's head feel warm. It was by no means unpleasant, even with the unmistakable lingering aroma of a boy's room after they'd jacked off in it enough times to infuse the walls with their musk. Duke stepped in and closed the door behind him, oblivious to his own scent.

The desk had only one chair, which the wolf pulled out for Ryder to sit on, then took a seat on the end of his messy bed. Duke seemed to then realise the state of his room and quickly tidied a bit. Ryder didn't mind, and found it cute how much the wolf cared. Eventually he was sat down before his books with Duke leaning over the side, observing and explaining when needed. Duke knew his stuff, and Ryder was learning a lot very quickly. There was some unspoken chemistry between them, and it made Duke very easy to talk to. The nerdy wolf seemed much more comfortable now that they were one-on-one, in the meat of studying, allowing him to capitalise on what he was good at.

Duke was cheerful, helpful, kind, and more interesting than Ryder had hoped for. The hours of baking in the wolf's oven of musky pheromones passed quickly until they stopped studying to have dinner downstairs with the rest of Duke's family. His father and older sister were cats too, though his father was orange-furred somehow. Ryder considered asking his new friend about it another time. After a nice, homecooked meal, the rest of his family disappeared off to some event claiming that they might not be back until midnight- plenty of time for the teenage human to satisfy his curiosities.

They returned upstairs to study, but did nothing of the sort. The schoolbooks remained open as Ryder asked a torrent of questions that Duke was more than happy to answer, if his swaying tail was any indication.

“I assume your family are cats because of your pet."

Duke nodded.

“So why are you-“

“A wolf?" he interrupted. “I've never seen a wolf, so I'm definitely one of those 'willpower' cases. Always had an unexplained fascination with wolves. I didn't realise how much I wanted to be one until it happened." He stretched out his arms and smiled, observing the fluffy fur that covered his body before adding, “This is fucking great."

“How long ago did you change?"

“I was one of the first in the school actually. It was pretty nice. For a while, the mean kids didn't dare go near me. One of 'em bragged that he'd turn into a dragon and set me on fire, but he ended up turning into a mole rat instead!"

Duke laughed to himself, and it was infectious. He had charm he didn't realise he had, and Ryder was being drawn into it. He found himself looking- no, staring into the wolf's sharp green eyes. Their gazes met and they glanced away, suddenly conscious about the chemistry they shared. After an extended awkward moment, Duke cleared his throat.

“Got any more questions-?"

“Uhm, yeah. Ah… What's daily life like for anthros, like your family?"

He crossed his arms and thought hard, imagining the routines of his feline family.

“Well, my dad works in a food factory, which was the biggest drama for us. They had a MASSIVE problem with fur getting everywhere, and several employees not being able to do their jobs. The factory needs a major overhaul, and they're still working on it I think. For now, they got dad wearing basically a hazmat suit to keep his fur in. He complains about the heat a lot. Thankfully he can still drive the car- he's not like some anthros that need seat adjustments to fit their tail through the seat, or god forbid a deer with antlers."

Ryder pondered the logistical and mechanical dilemmas every component of daily life was going through. They had it pretty easy as students, he thought.

“What about clothes? I saw your funny shoes"

The wolf let out a heavy sigh, “I hate those things. I'd rather go barefoot, but school is sticking with their dress code. Walking on pads is honestly great; I can see why dogs like running everywhere!" To demonstrate, the canine brought one of his legs up to bear, showing his foot's paw pad to the human. Ryder reached out to touch, getting approval from Duke's nod. They were soft and squishy, like on any other animal. Of course they were. He wasn't sure what he'd expected. Surprisingly fun to squish though.

“Shirts aren't too bad, unless you got a big head. Again, antlers. At least they got pants right. Long pants are a bit more complicated, but shorts are easy. They've got big leg holes for us anthros and-“ He turned around to demonstrate once more. “tail holes!"

Rather too enthusiastically, the brown wolf turned around and showed Ryder his rear. His tail poked through a gap in the back, similar to the fly of a man's pants, held shut by a button above the hole. Duke undid the button and pulled his shorts down slightly, unintentionally showing Ryder the top of his furry butt. The tailored apparel was interesting, but his gaze was drawn to that soft, brown fur. After marinating in it for so long, the scent of the room was getting to him, making his thoughts lewd and removing inhibitions as if he were drunk on the wolf's musk. His hands went for their tail, and with an approving nod, Ryder stroked along the fine fur, up then down, taking note of how Duke bristled when he rubbed it the wrong way. He smoothed the tail back down and pet the wolf for a while longer as his mind wandered, his eyes locked on their butt and his mind lost in a sea of perverted thoughts. This did not go unnoticed.

Ryder realised he'd been caught staring when he glanced up to make eye contact with the anthro, and turned to hide his blush. Duke hesitated and inhaled as if bracing himself, then in an unexpected move, he leaned in with sudden confidence and growled, “See something you like~?" The wolf didn't pull his pants back up, instead opting to tug them further down to reveal strained underwear. Ryder's dream of seeing a real equivalent to the toys he'd become addicted to recently was very quickly becoming possible. Likely, even, bordering on certainty. Duke leaned back on the bed as he kicked his pants away, allowing the stunned human to ogle him as much as they liked.

As if in a trance, Ryder sank to his knees before the big wolf with his gaze locked on that bulge. It was pudgy, like Duke's package overfilled the space to create soft lumps in the fabric. The bottom two spherical shapes were clearly his balls, but they seemed far too large to Ryder as they threatened to slip out the sides of the fabric, the hints of fur coating them visibly poking out in soft tufts. The more prominent lump was his fat sheath, hiding what could only be a monstrous canine shaft, though the human could spy a tip of rep poking out the top of Duke's waistband. He wanted more.

Ryder slowly fell forward, embedding his face into that soft wolf groin – Duke made no attempt to stop him, being just as horny as the other boy. The lingering musky, masculine scent that permeated the room suddenly intensified as he nuzzled into its source, filling his lungs with that addictive aroma. Ryder hadn't expected Duke to smell so good and found himself unable to pull away, but the insidious truth was that a side effect of Corvid 19 caused pleasant chemicals upon exposure. The intensity of the human huffing Duke's bulge was enough to make them crave more and more, urging them to pull that waistband down to their knees.

The wolf's fuzzy pouch was revealed, along with two hefty orbs hanging below. They were similar to oranges, Ryder thought, big enough to require a hand each. That crimson tip was steadily rising to reveal a length dripping with musky arousal. Upon seeing the glint of that oily precum, Ryder had the sudden urge to get closer. Duke watched with bated breath as his new friend sealed their lips around the opening of his sheath and gave a few eager licks. As the infected wolf precum touched Ryder's tongue, microscopic hairs began to grow on the human's cheeks. Duke leaned back as they slurped away at his emerging length, reconsidering his sexuality. The anthro wolf preferred women, but much to his surprise the eager boy was piquing his interest, or at least riling him up like a horny teenager unable to say no to a free blowjob.

Ryder felt the heated canine cock grow thicker as it emerged from Duke's sheath directly into his mouth. It seemed to taste better and better with every lick, which might have been a cause for concern if the human wasn't overcome with lust. The two young adults were oblivious to the minute changes happening to Ryder's body, starting small then accelerating the more infected fluids he ingested. He'd started this knowing he wanted to taste the wolf, and now that desire had turned into a craving as his brain rewired in subtle ways. He wanted even more, needed to press his lips to Duke's knot and suck the seed out of him. Ryder's cock was growing in his pants and beginning to stain them with his own pre, though his attention was fully on the wolf. His furless hands cupped those fuzzy orbs, feeling the heat and weight of a load he desperately wanted to swallow.

Little did they know that the virus caused rapid changes the more one was exposed to it, and the virus was most concentrated in fluids, especially sexual fluids. With each pulse of precum dribbling down Ryder's throat, waves of the virus attacked their human DNA to corrupt it into something else. Ryder was rapidly losing their humanity.

The human's cheeks bulged as he slurped and took every veiny inch into his mouth – it was slowly becoming too much. Duke was starting to get worried if Ryder could take it and considered helping them off when he finally noticed the human's skin was fuzzier than usual. Despite the thick distraction in his mouth, Ryder could feel a tingling throughout his body, and while it wasn't unpleasant it was certainly strange. It was hard to focus on anything in particular with how good it felt to suck the wolf off – a purposeful effect of the virus. Corvid 19 was not malicious and had no bad intentions, or any intentions in fact; like all viruses it simply survived and existed by being infectious and hard to deal with. A significant factor of its 'success' was attributed to being difficult to cure and the symptoms were not unpleasant, unlike every other virus. It was for this reason that Ryder was second to notice their body transforming through a swirling haze of pleasure.

“Ryder, you're changing-! T-this is supposed to take way longer!"

Duke could only watch in fascination as hair, or rather fur, grew all over their body. For the human it was a warm feeling, like sitting in a bathtub that gradually got hotter and more comfortable. In merely a few minutes, Ryder would complete the first couple days of transformation as he suckled on wolf meat. The anthro sitting on his bed observed a pelt of black fur coat the human's skin until there was no bare skin left and their hair morph into a red pattern that fanned down their back. Ryder noticed and felt his new fur coat, but he was far too enthralled by Duke's addictive fluids to stop gently bobbing his head.

“Wait! We should- wait..!"

Unknown chemical reactions began to flood Ryder's brain with pleasure in preparation for the next step of their transformation, causing them to moan and stain their underwear a little more as they ignored the anthro wolf's warnings. Almost imperceptibly the human's bones began to change shape and position while new ones were grown and others removed. What should have been an excruciatingly painful process instead had them humming pleasantly as if a heavenly masseuse were kneading their joints. As part of this, Ryder's skull deformed into something nonhuman, nor anything Duke could readily recognise. The former human's head pushed out as he slurped along the wolf's length to become angular, pointed and thin at the front then growing wider at the back. With an elongated muzzle, Ryder no longer had any issue swallowing the wolf's girthy length and even began to blissfully work on easing his knot into their maw. His tongue had evidently changed too, becoming far longer and manoeuvrable, allowing him to coil it around Duke's shaft. Ryder realised these changes should have been alarming, but he could not bring himself to worry – it felt too good, like the virus was giving him the body he never knew he wanted.

“Mrrff… Ryder" Duke gasped, torn between stopping the changing human and pulling them further onto his cock. It was incredible, almost magical for Duke to watch his new friend slowly shifting before his very eyes – the blowjob was nice too. With a coating of fur and a half malformed body, the anthro figured it was too late to stop; the transformation is half done, might as well be finish it, he thought. His canine knot was getting closer and closer to passing the threshold of passing through Ryder's lips as their skull finished reshaping – Duke thought it looked sleek, aerodynamic. For several minutes the wolf opted to enjoy the strange creature's warm maw and watch their body steadily rearrange itself, taking guesses at what Ryder was turning into. He definitely didn't look like a wolf, or canine, or anything else in Duke's mind.

Over the former human's dutiful slurping, Duke's ears flicked to the popping and grinding of bones; it was enough to make him wince, but going by Ryder expression it was anything but unpleasant. They seemed entranced in their task, enjoying his taste as well as whatever the transformation was doing to him. The wolf recalled his own transformation gradually taking place over a week, and being bedridden over the period of bone reformatting, so it was strange to see it fast-forwarded in a sense. For a while he curiously watched the position of their ears shift, their hands develop into claws, and the beginnings of a tail push out from their rear. It was bizarrely fast and slow at the same time, like watching a cloud shift high up in the sky. He placed an affectionate paw on the red fur that had once been Ryder's hair and gave them an encouraging petting.

Ryder felt heavenly. He couldn't get enough of that delicious precum, and the transformation was better than he'd ever imagined. The virus gave him what felt like a mouth designed to suck wolf cock, and he did so vigorously; Ryder took the entirety of Duke's length into his maw, working the shaft with smooth head movements and learning to use his surprisingly flexible tongue. He looked up at the wolf's half-lidded eyes and knew he was doing a good job. The transforming human redoubled his efforts to face-knot himself on Duke.

“Haah, I'm gonna cum~"

The brown wolf put his paws on either side of Ryder's head when he felt their long tongue squeeze around his length and tug him deeper like some sort of sea monster. Duke groaned, then pulled them onto him and gave a small hip thrust, finally popping his knot past their lips and causing his tapered tip to graze the back of their throat. That proved too much for the wolf. His toes curled and he bucked into Ryder's muzzle as his fuzzy orbs twitched within the former human's new claws. Ryder moaned as he gulped down wave after wave of delicious baby batter. The creamy pearlescent cum splashed against his throat and down, then absorbed into his body just as the precum had.

Whereas the wolf's pre was infused with the virus, his corrupted seed was thick with it; the accelerating changes to Ryder's body surged anew, announced by them cumming alongside Duke as dopamine flooded their brain. For the transforming human, it was like having two orgasms at the same time, running in parallel as he shot his last human load into his pants. The influx of chemicals to his pleasure centre effectively hid the pain of Ryder's tailbone extending into a long, serpentine shape – coated with fur like the rest of him and capped in a large fluffy tuft. At the same time, his legs reconfigured into the classic digitigrade shape of most anthros, ending in animalistic claws that similarly matched his hands. The changes were fast, yet slow. For a moment Ryder lost his balance as he kneeled on shifting legs, having to grab onto Duke's fluffy thighs.

The overstimulation wracked Ryder's nerves with pleasure, almost unbearably so. His body felt like dough as the virus kneaded and pulled it into a new shape – his true shape. In the throes of his transformation, it became obvious to him why some claimed the virus was a 'gift' for humanity. His legs felt strange, his tail felt stranger, both would take some getting used to. Simultaneous to the bone restructuring, Ryder felt a tightness around his chest and an incredibly strange sensation at his groin; he diverted a claw to each location to investigate.

The former human's shirt strained as Ryder grew larger, causing dozens of threads to snap and tear to accommodate. He thought the virus might be making him buff, but as he palmed his chest a spark of pleasure shivered through him. The hand between his legs felt the bulge of his cock, though it felt considerably smaller to him. There was also a very off-putting butterfly sensation in his stomach, or perhaps near it, but Ryder's attention was drawn away to his other hand. His pecs were noticeably larger, more sensitive, and pushing at the fabric. It didn't take a genius to realise that Ryder was developing breasts – a heavy pair if the ripping shirt was any indication. The tightness of the shirt was juxtaposed by his nipples bringing twinges of pleasure as they were forced to rub across the inside. Ryder made the decision use their new claws to help ruin his top, tearing it down the middle to reveal his growing tits. The extra mass inflating his chest was accompanied by a warm feeling that not only felt good, but felt right. His tattered shirt sloughed off to the side as he palmed his sensitive new mounds, feeling them continue to grow as he swallowed the last of Duke's load.

The wolf was left panting in the afterglow of his climax. His knot locked Ryder's jaw open, but they didn't seem to mind the discomfort with the way they purred as their tongue cleaned him. It was only then, in his post-nut clarity, that Duke realised his very seed had triggered the accelerated transformation, and his orgasm had finished it. He leaned to the side, getting a view of Ryder's strong tail, their black and red fur pattern, the strangely shaped head that reminded him of a cheese wedge, still containing his twitching red inches.

Duke had no idea what the hell his new friend had turned into.

The new creature's lips relaxed as he softened slightly, allowing Duke to pull his cock out with a pop as the knot came free. A strand of saliva connected his tip to Ryder's lips as they leaned back to inspect their new body; they now had a pair of breasts on their chest. They were large, easily handfuls, and each capped with a pretty pink nipple. The horny boys stared at those beautiful tits for an extensive moment before looking at each other in bewilderment.

“Are you-?"

“Am I-?"

Ryder's claws clapped to their mouth as the voice they produced was far higher than it had been. All pretence of modesty was lost as both young adults scrambled to inspect what had come of the transformed creature's cock. Ryder struggled to get their pants off their new animalistic legs, taking an awkward few moments to kick them away and then slip down his boxers to reveal-

It was gone.

In its place was the vagina of a woman, though not a human woman of course- there was some strange extended part that Ryder touched cautiously. With eyes like saucers, they looked to each other again with the realisation that the virus had robbed him of his humanity and his manhood. Ryder was, without a doubt, a girl.

“I think I'm a sergal-!" she said with rising excitement.

“A what?"

“They're not a real thing, they're like dragons. I think I get it now, the willpower thing-"

“Deep down you wanted to be a sergal?"

She nodded.

“And you wanted to be a girl?"

She paused, the weight of her transformation suddenly hitting her. Her penis was gone, and in its place there was presumably a fertile pussy and an elongated clit that she realised she could control to some degree. It flexed under her command – that would take some getting used to. She thought about what her insides looked like and realised that butterfly feeling from earlier was likely new reproductive organs growing amongst her other innards. Ryder brought her hands, tipped with pointed red nails, to her breasts to squeeze. They were extremely sensitive; enough so that the newly transformed girl made an involuntary gasp. Duke's softening length twitched.

“Is this even possible?" she breathed, looking to the more experienced anthro for guidance.

He made an unsure shrug in response as he called upon his memory, “I think I've heard about some cases like that online. Didn't believe it, but…" Duke looked down at his friend's beautiful breasts, their supple roundness hypnotising the male part of him. He shrugged again, “Guess that's one way to crack your egg. Congratulations."

Ryder kept feeling herself up, one paw playing with her tits and the other probing between her legs. Duke watched enraptured as the sergal pushed a finger into her virgin pussy, the tightness of it squeezing her knuckle. Given the sounds accompanying her masturbation, Ryder was quite wet already. The warmth of a horny teenage boy hadn't diminished, only grown into the flame of a horny teenage girl in the presence of an increasingly sexy wolf. While the virus made its final touches to her DNA, Ryder realised how right it all felt, how many of the 'victims' of Corvid 19 felt after being given their ideal bodies. All the confusing thoughts and feelings Ryder had grown up with as a boy finally made sense from the female perspective. She'd never felt comfortable in her human skin, like something was missing, as if there was a flavour she didn't know or a colour she'd never seen.

Now it was all crystal clear; Ryder was a sergal, a girl, a 'sergirl' if you will, and she knew what she wanted. She glanced to the wolf's crotch and saw that he was far from soft- he wanted it too. Getting up from her knees, she realised she was quite a lot taller now, a bit taller than even the wolf stud. She leaned over the astonished wolf, grabbing him by the shoulders like caught prey with a hungry look in her eyes, and asked, “Please, can we..?"

Duke gulped. He wanted to touch her so badly, to take his friend's curves into his paws and claim their luscious body. And why shouldn't he? She seemed to be offering, and damn was it harder than ever to say no to a sexy sergirl trying to get laid. He grinned, a streak of confidence lacing a shy chuckle.

“I'll be honest, it was fun to fool around with a boy, but I wasn't interested in taking it further. This changes things…"

His twitching paws reached out to Ryder's sides, feeling the soft skin underneath a pelt of fine fur. He traced up her sides, watching the approval beam from the sergal's face, then rounded on her front to fully grasp her heavy breasts. She made some sort of pleased purr and fell on top of the wolf. He shimmied up further onto the bed as Ryder followed on all fours, crawling above the handsome canine. With some help Duke tugged his shirt off and kicked his bottoms away, leaving both anthros naked on his bed, their sexes almost touching as the sergal hovered above him.

Some part of Duke wanted him to take the willing female and rut them into the bed, leaving them full of pups. He blinked that thought away. The sergal was above him, which was perfect; Duke was more than happy to let Ryder take control. There was an appealing aspect to laying under a horny girl and letting them take control.

“Take it slow. You're probably really tight, and I'm uhh-“

“Fucking huge?" she said with a smirk.

Seeing it fully out of his pouch and not sheathed in her mouth, Ryder finally had some scale to work with. It was comparable to the length and girth of her forearm, perhaps even thicker. It pulsed with angry veins as if alive and eager to breed. As Ryder lined herself up with his thick red inches, she found herself unable to close her paw around the midsection. The tapered tip was much thinner of course, and would be the only reason she'd actually be able to spread herself on him. The knot was something else entirely; it was the size of a softball, though that comparison still didn't do it justice. The shape was irregular, veiny, built for pleasure and sealing a bitch with his seed.

Yesterday, or even this morning, Ryder hardly knew a thing about Duke- now she was wondering what it would be like to be tied and impregnated by the handsome stud, made to carry wolf pups, or sergal young. Maybe a hybrid mix. This early into the pandemic there were a lot of unknowns, and a lot of discoveries to be made, starting with what a real canine cock would feel like inside her freshly minted sergirl pussy.

Ryder knelt above his waist, ready to descend onto that firm rod. His strong paws were at her sides, but only to give reassuring rubs; he didn't trust himself not to go too hard on his new friend if he were on top, so she'd be in control. At least for now. The tip of his pointed cock was leaking again, displaying his eager teenage virility as Ryder guided it to her lower lips. Almost as a second thought, her prehensile sergal clit wrapped around it to the surprise of both anthros. Duke flinched and let out a nervous laugh.

“That'll take some getting used to…"

“Tell me about it." She replied, tensing unfamiliar muscles to give the wolf a crude 'hand job' before sinking down. Ryder's paws went to her thighs, now using her sergal clit to guide him in. She lowered, feeling that warm tip part her folds, lower until she met firm resistance, then lower still.

Something in Ryder gave out and the first couple inches sunk in, forcing a gasp from both late teens. The sergal was suddenly hit with the sensation of having a hole they didn't know needed filling as the empty space in her abdomen slowly took on wolf cock in the most pleasurable way possible. Ryder eased down further into Duke's lap, moans growing loud as delicious curves and veins rubbed her insides in all the right ways. In only a few seconds, her virginity was taken and yet she wanted more. A new feminine yearning called out, demanding that she take the stud's seed into her body and carry his young; induced heat was another side effect of the virus altering her body's chemistry.

Ryder finally came to rest in her partner's lap, the curves of her butt almost hiding the fat knot her clitoral hood was trying to wrap around and tug in. It felt so right, so fulfilling, like a key sliding into its designed lock; turning the key would be taking his knot and opening the door to motherhood. It was so difficult to know how much of this the old Ryder wanted, and how much was caused by an influx of hormones from taking on the form she'd always meant to have. As that perfect cock stirred her insides, the attached wolf wiggling to show his impatience to continue, Ryder realised it no longer mattered.

Human boy Ryder was essentially gone, replaced by Ryder the sergirl, and now she wanted to carry Duke's pups.

“Mmmm you're so big~" she breathed, groping her tits and gyrating her hips.

“Not too big-?"

“Perfect."

Her upper half fell forward over the wolf, catching herself on elbows and touching her lips to his own. Duke responded by opening up to accept the kiss; they weren't lovers – maybe they were depending on who you asked – and there would be time to explore romantic questions later, but for now it was entirely carnal desire. Their elongated maws locked around each other, their heads tilted opposite ways to explore deep within their opposite's mouth. Duke discovered sergals have quite a long tongue as he deepthroated hers- not something he'd usually be in to, but the unfiltered passion was erotic and hard to say no to.

The brown wolf's paws scratched at Ryder's back, pulling her in closer, then moved to trace her soft sides, and then around the front to fill his palms with sergal breasts. Ryder was moving her hips again, steadily lifting off his slick spire until the cool air kissed everything but the tip before sinking back down just as slowly. She was taking her time, enjoying it, savouring the sensation of a real knotted cock stretching her real cunt; that thought alone felt almost as good as knowing she was about to get bred. Ryder went from sliding to bouncing as the tightness was fucked out of her, allowing for smooth penetration. They were still inexperienced when it came to sex of course, so sometimes the angle went down wrong, or his cock slipped out to instead spear along the outside of the sergal's belly, getting a shy giggle from them both.

They enjoyed each other's forms for what felt like hours, making out and exploring furred bodies as Ryder worked on spreading herself around that bulbous knot. It was taking too long- and Duke figured she'd had enough of a reprieve- so he grabbed her shoulders and rolled the sergal over on the bed, putting them from cowgirl into missionary with his cock still buried up to the knot. The wolf growled with a devilish grin that had Ryder merping in submission, then began to fuck the woman in earnest. He'd enjoyed watching the former human fucking herself on him, but now it was time to get the job done- to breed her.

Duke towered over her, arms on either side of her head like pillars trapping her in a prison of pleasure as he pounded her pussy with the strength of a professional breeding stud. The sudden change from her own controlled insertions to being taken by a strong wolf and helplessly fucked forced Ryder's first orgasm. She writhed under him, grabbing those arms for support as she struggled to regain control of her body while screaming through gritted teeth. He didn't even stop when he saw her eyes rolling in her head and instead kept fucking like a machine, encouraged from the way her inner walls squeezed him. He was close to climax, but not yet, not without knotting her properly.

Earlier Ryder had said “perfect", but she was really feeling the consequences of his size now; her powerful digitigrade legs felt like jelly, and an ache of soreness could be felt through the overpowering pleasure of having her pussy reshaped around Duke's cock. That first orgasm left her sensitive and weak-limbed, unable to stop the wolf from claiming her body even if she wanted to. Now that she'd tasted it, Ryder wouldn't trade the pleasure of being ploughed by thick canine cock for anything, not for masturbating with her old meagre dick or using it to fuck someone else; there could not be anything better than this, she thought.

Duke's bedroom smelled of sex, carnal breeding sex. It sounded like macaroni being fucked by a horny dog, accentuated with the creaking of a bed that would surely snap if they kept it up. Both anthro's had fur dampened with sweat and sexual fluids: the cause of the intense scent that filled their minds with thoughts of breeding. To Ryder it smelled of masculinity and virility, convincing her partially animalistic brain that this was a suitable mate to be claimed by. To Duke she smelled sweet and.. something else. Something addictive that made his mouth water and his cock hard, something he would later recognise as the scent of a bitch in heat.

As Duke's knot battered against the sergal's outer lips, she finally began to feel her formerly tight tunnel submit; her outer lips clung to the curves of his knot every time he pulled back, making a sticky suction effect that had Ryder whining for final penetration. Underneath a haze of orgasmic bliss, the sergal's fantasies flashed in her mind, suggesting a way to get impregnated she hadn't realised she'd wanted before becoming a woman. Ryder looked up at the wolf's glazed over eyes and worked up the breath to snap him out of his rut, despite how easily he was slamming the air out of her lungs with each thrust.

“D-Duke! Let me roll over, fuck me like a dog-!"

The wolf gave a few more sharp thrusts before finding the will to stop fucking the sexy sergal, even for a moment. He pulled his throbbing length free to inspect the mess he'd already made of Ryder's pussy; a trickle of pearlescent fluids snaked out to ruin his bedsheets even further. Had he cum already? No, it was all pre and the sergirl's own arousal, he realised. It was a lot though, and he wouldn't be surprised if the girl was pregnant already. No reason to stop then.

“You want my dog dick? My knot and my pups?" he growled, helping Ryder to roll over on shaky legs. She struggled to all fours, presenting her rear to the horny wolf on hands and knees with her strong sergal tail hiked all the way to the side, exposing her loosened sex and eagerly lowered prehensile clit.

“Please~! Please breed me Duke~"

“Good girl."

Duke grabbed her by the hips to ease her unsteady legs, then lined himself up. He would have liked to tease, to make her beg a little more while he rubbed his cock across her outer lips, but he was far too deep in a rut for that. The first heavy thrust sent Ryder collapsing onto the soft bed covers, only held up by the rear thanks to Duke's strong grip. He sunk every thick red inch into her fertile pussy, causing his swollen knot to slap against her entrance in time with his heavy balls smacking her thighs. He held there for a moment, allowing the sergirl to feel up his knot and sack with her snaking clit as he adjusted his stance. Once the proper position was found, his paw grips firm, Duke went all out.

Pounding her in missionary had turned Ryder into a drooling mess, but doggy style was the wolf's favoured position for a reason. It was all the access he needed and the leverage to utilise every part of his body to pound another orgasm out of the sergal almost immediately. Ryder whimpered into a pillow that smelled just like the man fucking her as she came around his cock a second time. Her cunt tried and failed to squeeze him inside since his hips were a blur, that perfect wolf cock entering her spasming tunnel multiple times a second. It was the kind of overstimulation that got people hooked on drugs, and made Ryder an irreversible addict for knotted canine cock.

She screamed “Duke" into his pillow while he rutted like an animal, every hip slam stretching her tunnel wider around his knot and bringing her closer to getting bred. That twinge of pain mixed amongst the ocean of pleasure returned as her outer lips finally accepted the fattest part of him, then he popped in- literally with an audible pop - to lock himself completely within a sergirl in the throes of a third sudden climax. Her clenching tunnel milked him properly while her clitoris appendage subconsciously caressed his twitching sack. Ryder's constricting walls and exquisite warmth brought Duke over the edge, finally getting him to empty his balls in the eager sergirl.

On instinct he snarled and hunched over the girl to bite the scruff of her neck in a claiming bite. His balls churned, his thick length throbbed, then ropes of white wolf seed painted Ryder's womb directly. She felt the cum slap inside her, followed by a blissful warmth that spread from her womb to every adjoining chamber. The female heat that had blossomed within rejoiced as it detected a bounty of semen drowning the flames of lust, delivering a surge of pleasurable chemicals straight into Ryder's brain – she would become addicted to this feeling, too.

Ryder moaned and writhed underneath the wolf, who hugged the sergal as close as possible while he deposited the contents of his sack into her fertile womb. The high of their mutual climax lingered for several minutes while they steadily slumped down, still locked and pulsing with pleasure. The tightness of Duke's knot in her formerly virgin pussy left the wolf's excessive load nowhere to go, causing it to push Ryder's belly out. Though neither of them could see it, the outline of the canine's length in her abdomen was slowly replaced by a bulge of cum, making the sergal look a few months pregnant as he continued to spurt small amounts of seed for the entire duration of their tie.

They panted and gasped in a semi-lucid state until finally Duke's jaw relaxed, then he licked the good girl's neck. Ryder felt like she was glowing, stuffed full, exhausted, on cloud nine- so many things. She had been impregnated by the sexy wolf and made to carry his offspring, yet the difficulties of childbirth or motherhood didn't faze Ryder at all. In the moment she lay there, the weight of the handsome canine pressing into her back and his entire cock pulsing with even more life-giving seed, the sergirl could not find a reason to regret any of it. In fact, she was wondering how often Duke would let her drain his balls in the future. The post orgasm clarity began to settle in, and she turned her head to ask a question.

“How long are we stuck together?"

“I don't know, never done this as a wolf before."

“So now what?"

He pondered that for a moment. “Study?" he suggested, leaning over towards his desk to retrieve the forgotten books.

What a silly, nerdy, cute thing to say, Ryder thought.

“Sure, why not!" she laughed.

The strong wolf rolled them over onto their sides and put her textbook in her paws, mindful of the various fluids staining the sheets below. They read together, Ryder asking and Duke explaining while they studied and waited for the canine's knot to soften a bit. Ryder hoped she would be able to study enough to pass the coming exams, despite the 'distractions' her new friend would no doubt provide. It was important to balance work with play anyway.

Duke hoped they would be unstuck by the time his family got home. It hardly mattered since his room smelled like sex, and probably some parts of the house too. The nerdy wolf's life was about to get a lot more interesting.
