Walk on the Wild Side [Man to Anthro Hyena Woman]

Tier reward for Awesome Bro

The war against the alien menace isn’t going well for humanity. Poor and desperate not to become another faceless soldier dying on the battlefield, Alan signs up to join the Mutant Corps, only to find things don’t quite go how he planned. They go better. 

~

The scent of oil was in the air, and the screeching sound of rusted exo-armour kept his hair standing on end. The hangar bay was quiet in all the worst ways; there were only the mechanical sounds of maintenance, none of the camaraderie or bravado that meant a battle well fought. They’d been decimated in the last fight, the Xendra’s were turning the tide of the war and it was only a matter of time before the alien menace was at their doorsteps. 

Alan looked down at the paperwork before him and bit his lip. It was amazing how one little sheet of paper could change his entire life; whether it would be for the better or for the worse was yet to be seen. Joining the Mutant Corps was no small decision, but everybody knew their existence was the only reason this moonbase hadn't been overrun already. 

The hangar bay opened, and in trudged yet another platoon of soldiers, with greatly diminished numbers. Behind them stood three figures: their Mutant Corp members. All three looked like they’d gone through the ringer, but they were alive, and their accelerated healing was already stitching their wounds closed. They were still humanoid, but were now taller, stronger and had taken on a more animalistic appearance thanks to the mutagen introduced to their system. A great, muscle-bound gorilla man, a rhino and a lion. Despite their strange appearance, everybody lauded them. 

Despite everybody's respect and gratitude for the Mutant Corps, though, there were still too few members. Joining meant being conditioned and mutated permanently. Even with the extra pay and power, only the most desperate troops applied. 

And Alan was getting desperate. 

His exo-suit was practically falling off, the last few battles, his laser had jammed and almost cost him his life. It was only a matter of time before he joined the ever-growing and disturbing death statistic. Just another grunt, lost to time. His credit account was basically empty; his army pay barely enough to pay for meals out here on the base above Earth. Even if the war were to end tomorrow, he’d have nothing to show for it but a few interesting scars. 

He’d filled in all the boxes, the only thing left was to select which animal to be merged with. Alan would have liked to be a lion as well, but they only had so much of each mutagen. His options were limited.

“Hippo, not likely,” he muttered, “Ostrich? Why is that even an option? Hyena…”

He didn't know much about hyenas, aside from the fact that they were famed for their viciousness. He’d seen a few at the zoo as a kid; honestly, they looked pretty cool. Being half hyena would certainly look better than being half hippo, that was for sure. 

Across the bay, the lion man roared, and half the room quaked in fear before jumping up and cheering. The regular camaraderie was coming back, fueled by the Mutant Corps' power. The regular soldiers gathered round as the rhino man scooped two easily onto his shoulders. They were shining stars, and they could probably afford as much food as they wanted. 

He ticked the box and signed the papers.

Alan stood tall in the sterile white chamber, shoulders squared, chin lifted, boots polished so clean they shone under the harsh fluorescent lights. He was in his best uniform with the insignia of the Earth Defence Coalition, and below that, freshly sewn on, the blood-red claw mark of the Mutant Corps. The patch was supposed to symbolise sacrifice, transformation, and ultimate loyalty to Earth.

But for Alan, it mostly symbolised hazard pay—not that he was going to let any of the scientists know that. Ever since he handed in his paperwork, people had been treating him like some sort of self-sacrificing hero; he could get used to it, honestly. He could almost forget that it meant being sent to the front lines the next time a battle happened. 

Alan swallowed nervously and tried to think of the extra credits. They’d make it worth it, plus, he’d be stronger, faster and better in every way. Still, he couldn’t shake the fear that came with knowing in a few seconds, some stuff nerd would walk through those doors and change his life forever. The door opened, and Alan flinched despite himself, but it wasn’t a stuffy-looking scientist who opened the door; it was the most gorgeous woman Alan had ever seen. 

Her white lab coat was buttoned tightly, showing off her curvy figure. Even though it was buttoned over her clavicle, he could see the buttons straining, hinting at the incredible bust that was barely being held back. Her dark red hair was held back in a tight bun, with a few strands loose to frame her face. Behind her clear glasses, sharp green eyes assessed him with clinical detachment. A shiny silver nameplate across her right breast read: Dr. Selena Voss. 

“Private Jaques,” she said, “You’re early.”

“Alan, please. Figured I'd show some initiative,” he said with a grin. “Anything for Earth.”

She arched an eyebrow. 

“That’s admirable. You do realise the survival rate for Mutagen Integration is only seventy-two per cent?”

This procedure had a failure rate? 

“Seventy-two?” he said, trying not to sound like he hadn’t done the reading. “Hey, I like those odds.”

She didn’t smile.

 “And the long-term effects are unpredictable. You’ll no longer be human, not fully. You’ll be stronger, faster—but different.”

He stood up and leaned casually against the medical gurney, flexing his arm just slightly. 

“Different’s never scared me. Besides, someone’s gotta stand between Earth and the alien hordes, right?”

She didn’t respond right away. Instead, she set her tablet down and moved to the injector tray. 

“You’ve passed all the screenings. Once I administer the mutagen, the transformation will begin within minutes. I will then have to leave the room so that the conditioning can begin.”

Alan swallowed. He didn’t let the nerves show. Not in front of her.

“Don’t worry, doc. I’m made of tough stuff. This uh, conditioning though, is that really necessary?”

“Absolutely. A human being suddenly filled with animal instincts need guidance. This will help the two halves become whole and help you come to terms with your new body to avoid any dysmorphia. Once it’s finished, you’ll feel as at home as a hyena as you did as a man.”

Alan did his best to look excited, rather than terrified. Maybe this was a mistake, maybe it would be better to be penniless and human than half hyena. 

“I have to say, I’m impressed you chose Hyena. We’ve had the sample for a while now, but nobody wanted to take the risk.”

Her eyes sparkled, that keen scientific interest made her whole face glow and Alan felt his knees go weak. Screw it, if she thought this was impressive, maybe he could woo her with all the extra muscles he was about to get. 

“I like to live dangerously, and uh, serve my planet of course.” 

He gave Selena what he hoped was a charming smile and rolled up his sleeve. As she pressed the needle against his skin, he said, 

“You know, once this is over, maybe we grab dinner sometime? For... scientific discussion, of course.”

That made her pause. Just a flicker. Then the needle slid into his arm.

“You’ll need meat. Lots of it. Raw, preferably. Your digestive system is about to become... unconventional.”

Alan opened his mouth to make a witty retort, but the fire hit him fast.

The mutagen scorched through his veins like lightning. He gasped, clutching the sides of the gurney. His muscles spasmed. Bones cracked. Alan grit his teeth and breathed heavily; the sound started to become more guttural with every breath, taking on an almost animalistic edge. Selena watched from the side of the room with wide eyes that had a hint of hunger to them before somebody reached inside and pulled her through the door. 

Alan wanted to give her a wink as she left, but his vision blurred—then sharpened. Every sound in the room became a piercing echo. He felt his jaw elongate, teeth erupting into jagged canines. Fur sprouted along his arms and chest. His hands curled into clawed paws. His tailbone split and grew. He dropped to his knees, panting, half-aware of the thick, inhuman growls that clawed their way from his throat.

Alan could feel other changes happening, too. His legs buckled for a moment before becoming digitigrade. That thick fur coated his swelling muscles, and he rose almost a foot in height. Despite the spikes of pain, Alan grinned: He may look a little strange, but he was an alpha male in every way now, especially the one that counted. 

He could feel his cock swelling, becoming longer and heavy between his legs, even though it was still soft. He could only imagine how incredible it would look once he got hard. Selena would be throwing herself at him. 

Then something else began to change. His chest started to swell. At first, he thought it was his pecs growing, but instead of turning into hard muscle, they started to look soft. They took on a rounded shape, and his nipples grew longer and darker pink, a stark contrast against his dark fur. 

“Wh-what?”

But…he had a cock, why was he growing breasts? It didn’t make any sense. Neither did the pleasurable warmth bloom in his lower stomach, watching them grow. 

When the transformation ended, Alan knelt in a puddle of his torn uniform, breathing heavily. His reflection in the polished metal floor stared back—a hyena-like muzzle, mottled fur, and slitted yellow eyes. Muscles rippled beneath his altered skin. He looked like a nightmare—a weapon. And in a strange way, he felt... good.

A sudden flash of light dazzled him, but when his vision cleared, he was met with an odd, swirling screen that instantly captured his attention. 

“Shhhhh, watch the spiral.” Whispered a voice, Selena. “Watch it, let your instincts calm.”

Alan blinked a few more times in confusion, each time his eyelids grew heavier as Selena’s sexy, soothing voice flowed into his ears. 

“You’re a hyena, a mighty warrior, but you must channel your bloodlust, all of your lust, in the right direction.”

That was the heat in his lower half, arousal. His hormones were going crazy, and the urge to rip and tear was there, but also to mate. The screen kept him locked in place though, hopelessly staring as Selena’s voice soothed his new instincts. She spoke of his body and how strong and powerful he was now. How he was a hero. Every soft word was like a stroke to his ego and his new huge cock. 

“As matriarch, you must protect your clan, your planet.”

Wait, matriarch? He was male, that didn’t…make…sense.

“Your powerful pseudopenis must be treated with care; you will rule.”

Pseudo…wait; in the back of his mind, Alan remembered something about that visit to the zoo when he was a kid. Hyenas were matriarchal; the females were bigger, stronger and meaner than the males. It was them that made the kills and led the clans, which means…when he took the serum…he became female too! No wonder nobody else has signed up to take it!

A flash of panic was instantly soothed by Selena’s voice. He was still staring at the spiral, letting her slowly program his new brain to adjust to his instincts. He couldn’t look away; he couldn’t tell her this was some sort of mistake. Was it a mistake? Alan wasn't even sure anymore. He was feeling more and more okay with it the longer he stared at that pretty spiral and let Selena’s voice flow through his ears. 

Yeah…being female meant being powerful. Being female meant being a leader. Being female was…great! The spiral slowly faded, and Alan blinked. She could feel the rippling muscles under his skin tense as the door opened and Selena walked in, eyes wide. 

“How do you feel?” She asked quietly. 

She grinned with a mouthful of fangs, her self-doubt was gone now. She was perfect. 

“Hungry.”

For a moment, she studied her. Then, finally, she smiled.

“Good. Then we’d better get you something to eat.”

“I wasn't talking about food.” Alan grinned, giggling. The sound had a manic edge to it; it made her sound dangerous, but judging by the way Selna’s pupils dilated, she liked dangerous. 

Alan took a few steps forward and reached out a clawed hand to trap the scientist between the wall and her new hulking, mostly naked frame. Her new pseudopenis was getting hard, and Selena licked her lips nervously. 

“You know, it’s actually a clitoris.” She whispered, trying hard to sound professional. “It’ll take some getting used to.”

“Why don't we practice with it?” Alan growled. “Touch me.”

“We shouldn’t…”

“But you want to.”

“...yes.”

“Then touch me, the matriarch has commanded it.”

Selena whimpered with want and gently reached out to grasp the cock, running her hands up and down gently as it got harder. Alan rumbled in delight as pleasure slowly filled her. The power, the control, it made everything feel so much better. A shiver ran down her spine, sending her mohawk-style fur bristling as Selena’s breathing got heavier.

“I’ve been waiting so long for somebody to take this serum.” She whispered. “Hyenas are so…intense, so wild, so…”

“Sexy?”

“Yes!”

Selena’s free hand came up to cup Alan’s new breasts, kneading them gently and making him groan and rumble. Those wild instincts were bubbling just beneath the surface. If it weren't for the conditioning Selena had given her, Alan would have thrown the woman down and fucked her roughly then and there. Something told her Selena would be more than willing, but she didn't want to rush things. She wanted Selena to enjoy this as much as she did. 

Gently as she could, Alan reached a clawed hand to the scientist's coat and cut away the buttons. Selena was naked underneath, and the hyena woman chuckled.

“You were hoping for this.”

“Yes.” The woman whimpered, “Oh god, yes.”

Alan slowly trailed his clawed finger down to her folds, pressing it inside so gently. Selena clenched around him, clearly getting off on the taboo and the danger. 

“Oh, your finger is already so big…”

“Just you wait.”

Alan was so hard now it almost hurt to think; she withdrew his finger, making Selena shudder with need before wrapping the fragile woman in her arms. They rolled back onto the floor, Alan’s tail thumping, and she sat the woman on her lap, holding her just above the now hard length.

“Ready?”

“Please!”

Alan was all out of mercy; he pulled Selena down to engulf her in one quick movement, fully impaling her. Selena let out a gasp of pure pleasure, her head falling back as her eyelids fluttered. 

They stayed that way for a moment, but Alan’s instincts could no longer be denied. She lifted the woman’s hips up until only the tip remained inside, then plunged her down again. Selena rose to the occasion and began to ride hard and fast, gripping herself on Alan’s wild hair. The tug made pain mix with pleasure, it was the best thing Alan had ever felt. 

Selena was already on the edge, gasping in need as she squeezed her tighter and tighter till finally;

“Oh yes!”

Alan felt her cum around him. The pressure made her own ecstasy swell, and she came as well. It felt strange, to have a cock and not cum the way she was used to, but she didn't care; it felt better than any orgasm she’d had as a man. Selena kept riding, cumming twice, then a third time before she was finally exhausted. Alan rumbled fondling, petting the scientist on the head as though she were the animal. 

“I’ve wanted that for so long.” She whispered. “You’re going to be incredible.”

“Those xenos won’t know what hit them.” Alan grinned. 

“But I will.”

Selena ran her hand over Alan’s muzzle, and he leaned into the touch. She’d be shipping out to another battle tomorrow, but there was none of the usual dread. She knew they would win now with her power. And if not, there was no way she’d die. Her days as a faceless mook were done; she was a matriarch now. A powerful hyena warrior, and more importantly, she had somebody to come back to. 

“I expect you to be loyal to me, pretty,” Alan growled, nipping at Selena’s ears.

“Of course. Who else could even compare?”

She had a point; there wasn't a person alive, mutant or not, who could tempt Selena away from her now. 

“We should get dressed, they’re waiting to confirm the serum worked so you can be approved for extra pay.”

Alan scoffed; extra pay was the last thing on her mind.
