SURVIVAL OF THE FITTEST

"Almost there..." It wasn't out of the ordinary for Lago to be found mumbling to himself when on the verge of a breakthrough, and even his fellow researchers could tell when he was about to finish a project. The coyote leaned in close to examine a few micro-organisms beneath his microscope, then returned to his beakers full of different-colored liquids and stopped to ponder something. "Now, if I...no, that wouldn't work. Dammit!"

The company Lago worked for, Chimera Biotech, was a large research facility dedicated to technological development via biological applications. Just three weeks ago, a researcher next to Lago had completed a prototype for artificial plants that could produce oxygen without need for the sun or water. Lago's studies, however, were much more risky when it came to what the company would allow.

"Lago!" came the voice of the coyote's boss behind him, a bobcat named Sev who stood on the upper balcony with his arms folded. "My office, right now," the feline said with a scowl.

The coyote sighed and removed his sterile gloves, then discarded them on his way toward the stairs. When he entered Sev's office, the wildcat was already signing paperwork on his desk.

"Sit down," Sev instructed the coyote, who had already seated himself in the leather chair facing his boss's desk. Sev then massaged his forehead and set his pen down. "I received an anonymous tip that you're splicing hawk and lion DNA in your work area, right next to your chow mein. I don't know what kind of flying noodle monster you're creating but you'd better put a stop to it right here and now."

Lago rolled his eyes and twiddled his thumbs on his lap. "Anonymous? C'mon Sev, you're looking over my shoulder so much you might as well pluck out my eye and become a parrot. I'm merely comparing gene sequences for a base platform..."

"Base platform, my ass!" Sev growled. "This building nearly got condemned after you revived that dead manatee with an artificial brain. It's still locked up in cryo; hell, we can't even legally kill it because we aren't sure if the damn thing is self-aware or not. This Doc Frankenstein bullshit ends now, or your career does." The feline pushed up his glasses and resumed signing his paperwork. "You'll start from square one with the Bulgari project tomorrow and hand over any material pertaining to your current research over to me immediately."

Lago raised an eyebrow and leaned forward. "If my research wasn't allowed here then you'd have me get rid of it, not try to steal it. Unless you're trying to get both of us fired, that is. Also, Bulgari's way beneath my level. I could write a longer formula on my thumb."

"You might be talented," said Sev to the coyote. "But your misuse of your skills has made you a liability to this institution, and on top of that a pain in my ass. If I don't see all of that material on my desk by the end of today, you'll see a pink slip on yours in the morning."

Lago stood from his chair and turned toward the door. "Very well," he said to his boss. Leaving Sev to guess at what his next move was, the coyote ran hurriedly down the steps and continued his research. "Try to take my work from me," Lago muttered, grabbing two vials and extracting a drop of each before squeezing both drips onto the microscope slide. "We'll see if I let you." A wild smile crossed his face when the organisms reacted to the chemical mixture, their shapes morphing before his very eyes. One more step and he was there.

*****

Later that night, Sev opened up the door to the facility with his keys and glanced behind him cautiously before entering and locking it shut. Not often was the bobcat compelled to sneak places, but with Lago's newest project nearing completion he had to see it for himself. The coyote was stupid enough to leave his research materials out in the open on the table where he had been working on them all day. A scientific breakthrough like this would need a stronger mind than Lago's at the helm, Sev thought. This was his chance to become one of the wealthiest inhabitants on Earth, and the formula sat there unpatented and functioning.

"Complete transformation..." Sev had to say it aloud to force himself to begin to entertain the possibility. People who inwardly identified as a different gender or species would become what they desired with minimal pain and genetic restructuring. Limbs could be healed, cells could regenerate; perhaps even the dead would rise again. Lago had engineered a complete and perfect biological Philosopher's Stone, and Sev had the means to copy it and patent it himself.

The feline's ear flicked when he heard something in the building with him, and he quickly found a hiding spot in the corner beneath one of the other desks. Lago had somehow managed to get in, and the coyote was now looking left and right as he walked to his desk. If the coyote could create a means to harmlessly alter biology, Sev concluded he would at least be able to forge a keycard.

The coyote rubbed his hands together excitedly upon approaching his desk, then punched a code into the keypad by the top drawer and pulled out a syringe full of blue luminescent liquid. He stared at it in a trance, then procured an alcohol pad from the table and began cleaning an area on his shoulder.

He's going to test it right here? Thought Sev in a panic. What if Lago had already decided on something with uniquely heightened abilities or defenses? Worst of all, what if it actually worked?

"The power of transmogrification in the palm of my hand," said Lago aloud, as Sev guessed he'd been waiting to since he first dreamed up the idea. The coyote then turned to address an invisible audience, pacing with the needle held high in his hand as if he were giving a public demonstration. "I'd like to thank my fellow researchers, for staying out of my business of course." Lago no doubt imagined that would be a point when the audience laughed. "I'd also like to thank my family and friends, my mentors, hmmm why not God, the great minds of the past, and of course..." Lago had stepped out of Sev's view, and then he heard the coyote's voice speak right next to his ear. "...My lovely assistant."

Sev's scream was muffled by Lago's hand when the needle pierced the bobcat's shoulder fur, and Lago made sure every drop of the glowing blue liquid was pushed into his boss's body. The coyote then tossed the syringe absent-mindedly and backed away, watching Sev writhe on the floor.

"Now you get to see what I've been working on up close," echoed the coyote's voice in Sev's ears as the bobcat's vision blurred, and the feline's nose erupted into a beak. Wings sprouted from Sev's shoulders and his clothing tore away as he knelt in shock, feeling his toes rearrange into talons and his tail become more lion-like. Sev screamed while Lago laughed. "It's no wonder you wanted to steal this information for yourself. You were smart to covet my accomplishment. Unfortunately for you, I saw this coming years ago."

Lago pulled a smaller glowing green syringe from his shirt pocket and disposed of the cap, then drove it into his own shoulder and roared. He transformed into a similar creature as Sev, but much larger and stronger, and a lot more quickly than Sev was changing.

"I perfected this formula a long time ago," said Lago from his beak as his clothes ripped to shreds and his wings stretched magnificently behind his back. His whip-like tail knocked a few beakers from a nearby desk as he strode toward Sev, who was cowering on the floor. "The only question was how I would protect my work before I made it relevant to consumers, and I think you know the answer already." Lago's glowing green hawk-like eyes peered maliciously down at Sev, who was still completing his transformation with a look of disbelief and dread on his face. "I gave you a different compound," said Lago.

"A different...one?" Sev gasped, panting on his hands and knees while staring at his vague reflection on the floor. They had both been transformed into anthro griffins, and Sev's form was considerably weaker-looking than Lago's. "What do you mean?" the former bobcat asked with nearly a sob.

Lago strode up to Sev and glared down at him fiendishly. "I reprogrammed my original formula to make you smaller and weaker, if you hadn't noticed that already. If you want to know what gap there is between our strengths, then allow me to offer you a demonstration." Lago pried a solid metal desk affixed to the floor which held another researcher's progress for the Bulgari project sitting on top of it and let the fragile contents slide off and break as he held the desk high above his muscular form, then swung his body around and launched the desk up at the balcony in front of Sev's office. The table broke through a marble corner of the balcony and the glass guard on front of it, then through the glass door of Sev's office and into his workspace.

Sev backed away from Lago, scooting across the floor and holding up a hand. "Jesus...what are you going to do to me?"

It disturbed Sev that Lago's wild-eyed smile was recognizable even as a mythical avian crossbreed, and the larger gryphon replied with a hope-drowning sneer. "That's the beauty of it, Sev; I don't even fucking know yet."

Sev turned away to stand up and run, but Lago's form crashed to the ground in front of him. Lago had moved so fast that Sev hadn't even heard the other gryphon's wings flap.

"Don't bother trying to fly away from me," said Lago, looking down at the weaker male. "It took me days to learn how, but your brain gets used to it."

"You can change back?" Sev asked with a faint ray of hope in his mind as he stood. "Then please, I'll do anything for you to change me back too!"

"Let's not start with the bargaining just yet," said Lago as he circled around the smaller male, inspecting him closely and sliding a hand down Sev's back. "You turned out better than I'd hoped. It would be a shame to see you get damaged before I use you how I intended." Sev felt the more powerful male's hand grope his surprisingly round ass and poke a finger into his hole, and the smaller gryphon cried out with a start as a glowing blue cock that matched the color of his eyes spilled from his sheath and pointed straight up, already aching to ejaculate.

Sev quivered in unimaginable pleasure from Lago's finger up his ass while staring down at his throbbing luminescent gryphon cock. No doubt he'd be able to cum just from bouncing up and down a little. "What...what is this?" Sev asked, wading through the miasma of pleasure in his brain in order to remember how to speak.

"An unexpected side-effect of the transformation," Lago answered him. "When my first attempt was successful, I discovered that I had granted myself extraordinary power, heightened awareness, and one more thing...an impossibly uncontrollable desire to mate." Lago tightened his arm around Sev's neck and pushed his finger deeper into the smaller gryphon's rectum, causing a small amount of precum to spurt from Sev's twitching blue member.

Sev then slid out from under Lago's grip and darted away, quickly taking flight up toward the glass ceiling with blinding speed. He couldn't explain it, but along with his new biology something in his subconscious gave him the instinct to know how to fly, and to escape as fast as he could. Sev burst through the glass ceiling of the research facility and flew high up in the air toward the nearby skyscrapers of the city around him, but before he made it very far he felt the wind leave his lungs when a kick to his ribcage sent him tumbling onto the rooftop of an old brick building below him, right next to a grimacing gargoyle statue perched on the corner of the structure's roof.

Lago landed carefully next to Sev so as not to burst through the roof with the force of his landing, then stepped on Sev's chest and held the injured gryphon in place under his talon. "Trying to get away won't do you much good," said Lago to his victim. "The new serum gave you more weakened abilities the original one gave me. Not only are you physically inferior, I also ensured that you were given more...feminine attributes." Lago rolled Sev over with his talon and gazed down at Sev's curvy buttocks beneath his swishing lion tail, inspecting the small glowing blue hole in the middle. "It'll be a little while before I perfect my 'gender-bender' formula, but for now you're as close as I need to have my way with you properly."

The less powerful gryphon lifted a hand and tried to crawl away, but Lago's hand grabbed Sev's head and roughly pressed the side of Sev's face against the ground. The larger gryphon leaned in closer to Sev, and a thick glowing green gryphon dick spilled from his sheath. It was twice as big as Sev's and pulsated with activity, looking twice as desperate to banish the load from Lago's balls.

Lago slid against Sev's slender, effeminate figure and ran his lion-like hands up and down the smaller gryphon's flat chest from behind, then pressed the pointed tip of his glowing green shaft in between Sev's plump butt cheeks until he found the hole. "You want my life's work?" Lago asked him menacingly. "Then take it, every inch of it, and know that you've been outdone." With a fearsome screech, Lago drove his hips forward and rutted his throbbing gryphon cock deep in Sev's anus all the way to the hilt, and the smaller gryphon gasped from the agony of the forceful entry. "Am I a pain in your ass now, Sev?" Lago asked before laughing uproariously, holding his boss down and taking advantage of him right there on the roof of the building.

Sev's vision blurred every time he felt Lago's monstrous cockshaft pound into him, stretching open his sensitive blue rim as the pointed tip of the glowing green dick nudged his prostate. Soon overcoming the immense pain were unstoppable waves of indescribable pleasure beyond the limits of Sev's imagination. As much as he despised the idea of being taken by force, especially by his subordinate and as a gryphon practically in public, Sev could do nothing to fight his increasing desire to be fucked even harder. This was better than any drug he'd ever tried, any orgasm he'd experienced; this was the pinnacle of ecstasy for him, and he hadn't even been driven to climax yet.

"Something tells me you're enjoying this even more than I am," said Lago from above him, dominating the smaller gryphon with his hips slamming against the other male's rear. "After you get a taste of what it's like, nothing will ever satisfy you again. I might as well keep you alive for my private fuck toy...mmmggghhh!" Lago's beak opened with a screech when he suddenly came, gushing a bucketload of gryphon sperm deep into Sev's ass and decorating his boss's rectum with his seed. Lago panted and recovered, keeping his dick buried inside of Sev for a moment longer while he felt the other male's rim clench around his throbbing green cock. "So, how about it?" Lago asked him. "Do you want me to stop?"

Poor Sev was on the verge of cumming and he was afraid that feeling that good might kill him, but every instinct compelled him to beg for more. "No, please!" he whimpered, and his answer embarrassed him but the instincts he was given were more than knowing how to fly; they were urging him to be used for breeding. "Please, mate me!" Sev cried out desperately, swallowing his shame to admit defeat. "This feels too good, I'm begging you...make me yours, Lago!" Sev had never been interested in the coyote to begin with, or anyone for that matter, but this new transformation had changed more than the bobcat's appearance. He wanted the larger gryphon to fuck him as if it was his very purpose in life.

The taller gryphon's menacing green eyes lit up victoriously. "So, you'll be my slave?" Lago asked him. "You'll exist to make me cum, and after I change you back I'll still have my job even if you lose yours?"

"Yes, anything!" cried Sev, feeling his erect blue cock twitch beneath him urgently. "I don't care if I ever do change back, I'm yours to use how you want!" It wasn't the threat of Lago being able to kill him with his bare hands that convinced Sev to make this change, but his very DNA to submit to the greater gryphon's power and please him to the extent of his desires. "Please, Lago...no, Master...please, breed me!"

Lago was satisfied with the other gryphon's compliance, and so he resumed fucking Sev on the ground. "Then you'll be my pet, and you'll answer my every call, fulfill my each and every command," Lago said before standing and lifting up the smaller male by his hips. He then slammed his dick upward into Sev's ass, lifting the smaller gryphon's talons from the ground and bouncing Sev's ass up and down on his twitching dick. "I'll test my new prototype on you next week, and then you can be a female for as long as I want," Lago said, thinking aloud. "I'll breed you and see if you can make little gryphon babies for me, and we can raise them."

Sev moaned ecstatically at the thought of being impregnated with Lago's sperm and carrying his young, his blue cock bouncing up and down in front of him as Lago walked to the edge of the building. "Oooh...ohhh yes, Master, I'd love to!" he eagerly replied with a surge of estrogen through his veins. "Please, let me carry your little ones! It would be so gracious of you...OOOH!" Sev gasped and steadied himself in the air by flapping his wings, hovering in front of the stronger gryphon who held him by his hips and fucked him on the edge of the roof. The weaker male looked down at the busy traffic in the street below, watching the cars honk at each other beneath the streetlights in the middle of the night, and right then his climax finally arrived.

A chorus of heavenly feelings rushed through every corner of Sev's body when he came, ropes of gryphon seed arching out from the tip of his glowing blue member and falling down onto the busy scene below. The pleasure was so intense it set his nerves on fire and nearly made him delirious, but he counter-thrusted against Lago's powerful dick buried inside of him as the hands-free orgasm continued launching cum from his twitching shaft.

Lago then came a second time, encouraged by the sensation of Sev's perfect anal walls clenching around his green shaft and massaging every millimeter of the sensitive flesh as jets of his sperm painted Sev's prostate white. It was Sev who screeched loudly this time, gaining attention of some of the pedestrians far below who didn't have time to dodge the sticky gift from above. Lago roared and fucked his mate with loud, firm smacks until the pleasure had subsided, then slowly pulled out of Sev and set the weaker gryphon on all fours beside him.

The sight of Sev's gaping blue anus doused with cum excited Lago, even more so when the submissive gryphon turned to look at Lago with a blissful smile as if the two had just enjoyed their first honeymoon sex. Sev then crawled before the taller gryphon and began licking the cum from Lago's shaft, careful not to poke it with his beak.

"I can't wait to try you out when you're in female form," Lago said, running a hand along the side of the submissive's face. "Whenever I want to, I can call you out of your office and inject you with the serum, then fuck your tits and pussy wherever I feel like doing it. When I get you pregnant I'll keep you at my house in a birdcage until you're ready to have my young. You're nothing but my little slut now."

Sev's glowing blue eyes looked up at Lago sensually in agreement, and the smaller gryphon swallowed down every drop of his master's cum that he'd licked from the cock that would one day sire their offspring.

"Stacy to the manager's office, please," came a voice over the intercom at Chimera Biotech. Several weeks later, the facility had been repaired and work had gone on as usual. Lago had been given a significant raise, and Sev had taken a devastating pay cut; nobody quite knew why, but they all suspected that Lago's "classified project" had something to do with it one way or another.

Sev's secretary walked into the bobcat's office and straightened her glasses. "Yes, sir?" she asked him.

"Stacy, I need you to redo my schedule for the next nine months," said Sev to the attractive young mouse.

"Again, sir?" she asked him with a sigh as she pulled out her work tablet. "And a whole nine months this time? What for?"

Sev exhaled slowly and closed the briefcase on his desk. "I'm going on maternity leave."

"Maternity leave?" Stacy lowered her glasses and stared at Sev blankly, waiting for an explanation from him. "Sir, I don't think your benefits will cover that."

"Just think of some loophole and make it work," Sev said impatiently. "I need to be leaving right away."

Stacy glanced at her tablet and pulled up Sev's digital calendar. "You could use up the rest of your vacation and sick days, but I'm afraid that would mean three whole months of unpaid absences. Is something the matter, sir?"

The bobcat grabbed his coat and briefcase, then walked toward the office doors in a hurry. "I guess I'll just have to make do." Stacy, although confused, complied with her boss's request and began clearing tasks and events from his schedule.

While Sev made his way down the stairs, he overheard Lago conversing with a fellow researcher. "It's really quite simple once you know what you're looking for," Lago told his colleague, neglecting to cast a glance at the bobcat walking by. "I mean I can't give you my whole recipe in one sitting, but if it works then this could be quite revolutionary. Natural selection doesn't merely apply to the evolution of a species, it's in our very genetic code." When Sev made it to the door, he looked back to make brief eye contact with the coyote and Lago gave him a smile that was almost sickening. "Some of us are built to succeed, and others are not."
