“I’ll do it.”

Casey’s words seemed to hang in the air, and she swallowed hard with a smile on her face. The power she’d used to change Kevin was… Well, it was intoxicating. She couldn’t think of a better word for it, and didn’t want to think right now. All she wanted was to revel in her newfound power.

And what power it was! She could feel it coursing through her body, a mystical energy that not only spoke of unearthly force, but also told her how to control it. She gasped, lifting a hand to her chest, then looking up to Martin with a smile. She didn’t know what he was, and she didn’t care.

“So? How is it?” He asked, a quiet smile on his face. He studied the black haired girl with an almost predatorial curiosity, like a tiger who’d just taught its cub how to fend for itself.

“It’s… Good. More than that, I can’t explain it, and I can’t thank you enough-” Casey began, only for Martin to hold up a hand to forestall the motion.

“No, no. Don’t try to thank me with words. Thank me with actions. I need new bitches for my kennel, after all. And I suspect you know just the bitches to turn.”

A slow, quiet smile dawned on Casey’s face.

 

The two of them walked into the Kenmark University locker room, and Casey smiled as all five of her victims looked towards the sound of the opening door. They were changing into their uniforms, and that’s where they froze at a click of Martin’s fingers.

“Hello, girls.” Casey purred, smirking. They weren’t entirely frozen-their eyes were still capable of moving, capable of showing the immense confusion each of the girls felt. “I know, I know. We’re such a good team that I really shouldn’t be doing something like this. But I found a new partner, as you can tell. And unfortunately for you, he’s asked me for a little favor. Martin?” She looked up to him expectantly. “Pick my prey.”

“Oh, I like that attitude.” Martin smiled calmly, pointing with a finger towards Felicia, the Latina of the squad. She was really beautiful, and Casey had always been jealous of that. It wasn’t a malicious jealousness-had Martin not asked, she’d surely let the girl remain human. But needs must, and all that.

Felicia shuddered as she regained the ability to move, and she looked up to Casey with wide, pleading eyes. “N-no! You can’t do this to me! Please, whatever this is, you don’t need to do it Casey, you know me!”

“Sit, girl. And shush, adults are talking.” Casey’s smile widened as Felicia fell onto all fours, her jaw snapping shut. “Mmm, that’s better. Now, Felicia… You’ve always been the strong, fearless one. And yes, you’re pretty. I think I’d like you to be something noble, something dignified. You’re smart, you’re protective… You’ll make a fine German Shepherd.”

The change began almost immediately, Felicia’s eyes widening as her tongue swelled in her mouth. It grew, grew larger and larger with every second until it nearly choked her with how large it was. Then it spilled from past her darkening lips, flopping beneath her chin as she began to pant.

“Crrassrrowrr!” She tried, her voice deepening in a matter of seconds. Her tone became harsh and guttural, and she whimpered like a dog as she fell onto all fours, her ample bosom heaving with exertion.

This change was Casey’s first to inflict, and it wasn’t nearly as gentle as the girl had intended. Felicia rolled onto her back with a whimper, her arms cracking and popping as they reshaped. She pawed at her clothes, squirming on the ground, looking up to her friend with a canine whimper of fear.

Casey knew that she should have been afraid of her power; of what she’d done. Yet all she could think of was how incredible it was that she had this power, and how easy it was to change her friend. She watched as the last of Felicia’s appearance gave way to that of a German Shepherd, her dark hair shrinking into her scalp until it was the same length as the rest of her new fur coat.

“Oh, that was… That was something.” Casey purred. She turned towards Kimiko next, the cute Asian on the cheer squad. “Martin… Her next.”

Kimiko shuddered as life returned to her, opening her mouth to ask… Something, anything. Casey didn’t spare her the thought required to guess what it would be. Instead, she let the transformation do the talking for the woman.

“Growf!” Kimiko barked, a canine whimper following the sound. Casey had worked fast with her voice, and for good reason.

“You know, your voice always annoyed me. Not the accent, the pitch. Like, I get that you think baby talk is cute, but… Honestly, I’d rather hear the barking of a dog.” Casey smirked cruelly, tapping the girl on her nose.

Kimiko whimpered aloud, her eyes crossing as she watched her nose begin to darken. It grew wet and spongy in a matter of seconds, just like Felicia’s had. Then she licked it, her tongue lengthening and slurping out of her mouth to facilitate the canine motion.

The Asian girl whimpered, distressed, her slanted eyes rounding into a more canine fashion. She scratched at her neck aggravatedly, an old habit that turned to be rather fitting for her current situation. Long fur was curling up from her collar, thick and bushy.

It was spreading all over her body, from head to toe. After all, Casey was in the mood for something a little furrier this time. An Alaskan Malamute would suit Kimiko well. The fur was getting so thick that her tight clothes were stretched taut on her form, a form that was broadening into the body of a large dog.

Kimiko whimpered and pawed at her shirt, her fingers shortening into the small stubs of a dog’s paws. Her nails lengthened into claws, and they soon dug into the fabric, tearing it. The small tears widened in a matter of seconds, and her clothe split apart, leaving her naked.

The girl fell onto the floor, her broadening palms slapping against the changing room’s tile. She whimpered and whined, but could do nothing as a tail burst from her backside, its thick and shaggy length waving in the air.

“Aw, look at that! Someone’s wagging. It’s almost like you’re enjoying this, you little mutt.” Casey chuckled, turning her back on the girl as her face stretched out into a muzzle, as her ears slowly widened on her head until they were the triangular ears of her breed.

“I think… You’ll be next.” Casey pointed to Kirsten, grabbing her ears in her hands. She pulled on them hard, stretching them out as though they were clay. A bit at a time, they lengthened and grew larger and longer and larger still. They widened and stretched until they hung almost to her shoulders, and brownish red fur that almost matched her hair raced out to cover them.

“Kirsten, Kirsten…” Casey spoke softly, watching as she shuddered, no longer paralyzed. “You really are cute, you know. Redheads, and all that. I know you always used to say you had the luck of the Irish, so what better body could you have than an Irish Setter?”

“I’m not a dog, I’m your friend!” Kirstin whimpered, reaching her hands out to Casey, recoiling as she watched them begin to change. Her slender digits bloated, red fur spreading out from the backs of her hands until it covered them. She turned them around and watched as her palms swelled as well, growing thick and dark.

“Well… For the time being. But that’ll change. You’ll change.” Casey said with a slow smirk, watching as panic began to set into Kirstin’s green eyes. She hadn’t noticed them changing on the other girls, but Kirstin had a bright enough gaze for it to be readily apparent.

Her green eyes were beginning to darken, an inky brown spreading across them like dye being dropped into water. Her irises widened and she shook her head in distress, clearly feeling this change. She rubbed at her darkening eyes with a whine, and by the time she looked up to Casey again her gaze was nothing more than that of a dog’s.

“See?” Casey purred, cupping Kirstin’s cheeks in her hands. She pulled slightly, humming as the girl’s face stretched out into the long muzzle of her breed-to-be. “Mn, how does that feel, I wonder? It must feel so odd to have such a long snout… Such a furry body.”

Kirstin whimpered, her frame shuddering as she felt the fur come in. Casey pressed hard on her shoulders, forcing her onto all fours. She let out a distressed whimper, but her body cramped and cracked, her hourglass figure regressing to a canine shape that left her trapped in that pose. Her tail came in along with the last of her long, thick fur, and she flopped her ears in distress.

“And then there were two.” Casey chuckled, letting the last of Kirsten’s changed wash over her. “And… What better form for the fireman’s own daughter than to make her a Dalmatian?” She looked to Melody, a pretty black girl who gasped as life returned to herself.

“Oh my God!” Melody gasped, looking up to Casey and narrowing her eyes. “You bitch! You think that you’re going to have your way with us, with this?” She glared. She reached for her purse, planning to grab her phone and call her family.

Sure, her dad wasn’t a cop-but that didn’t make him any less intimidating. She was going to have him bring over some of the boys from the brigade and… Her tailbone was aching, really badly. The girl’s eyes widened and she looked to her backside, a strangled whimper erupting from her throat.

“No calling for daddy, Melody. He’s not going to get you out of this one.” Casey grinned to the dark-skinned girl, watching as her towel was pushed from her frame by the slow growth of a tail. Melody looked to it with shock, whimpering as she watched it grow out longer and longer.

This tail wasn’t like her friends’. It was slender and shorter, with far less fur-enough for a coat, but not enough to be called bushy or shaggy.

Worse, an impulse was setting into her mind, one that she couldn’t deny. She wanted to run around, to chase it, and to act like a common mutt. She’d never been one for urges like this in her life, so she was singularly unprepared for this.

Casey laughed out loud as Melody fell onto all fours, starting to scamper in a circle like a dog. She’d hoped that the girl would take to the changes, but to think they’d worked so well! It was outstanding!

“Oh, look at the dumb dog, chasing her tail like a bitch! Go on honey, let’s make it a little easier for you. How about… The more you chase, the more you change?” Casey cooed, grinning as Melody’s dark eyes widened in fear.

Her brown skin began to lighten in areas and darken in others, until she was coated in a black-and-white pattern that befit a Dalmatian. Her lips thinned, darkening from their light pink in a matter of seconds. Worse, her tail kept wagging, taunting her just out of the reach of her human jaws.

She could feel her body changing, could feel her arms and legs thinning. Her shoulders and hips popped, and she stumbled and fell onto her face. She writhed on the ground, looking down to her limbs as they dwindled away.

Then her breasts, her large and ample bosom, began to pull back into her frame. She whimpered, pawing at them with both hands, eyes widening. It was hard to make her hands reach her breasts with her arms so changed, she could barely turn them at the wrists enough.

Still, she managed enough to feel them losing their heft; to feel them shrinking away to almost nothingness. Her palms were beginning to change as well, swelling and getting coarser. She pressed them against her chest, choking out a sob only to choke on her tongue a second later.

It had swollen in her mouth, erupting from past her lips along with a canine exclamation. “Rorf!” She barked, whimpering and groaning as new teats settled along her chest. The impulse to chase her tail somehow still existed, and she forced herself to roll onto her paws.

Then she began to chase her tail again.

It was easier this time, every circle of her body feeling more and more natural to herself. Soon her ears were flopping with every bound of her body, and her hair fell out from her scalp in curly bundles. Finally, her nose and mouth stretched away from her head, her new muzzle snapping around her tail. She wagged her tail madly with a whimper, proud despite herself.

“Oh my God, this is just too funny! It’s such a shame that the fun’s going to have to stop here.” She looked to Mia, chuckling. “Oh, don’t give me those puppy dog eyes, they remind me of my old puppy. Who… Come to think of it, was a Black Lab…”

Mia shuddered, gasping with relief as she was able to move again. Then she gasped once more, feeling a pleasure that she couldn’t quite reconcile with her current situation. Her heart pounded in her chest and she looked down, down to her sex.

She was wet, wetter than she could remember being in her entire life. Her pussy was hot, and her clit ached with need. Desperately, she began to pleasure herself, thumb trailing against the nub as her fingers dipped into her sex.

“Just like my old dog.” Casey hummed. “She never could stop teasing herself, you know. At least once a day you’d find her lapping away, loudly slurping with that tongue of hers again and again. You know… Let’s have you do that. It’s not very fair of you to be able to use your hands now, is it?”

Mia whimpered, feeling her fingers begin to stiffen and shrink. They were getting stubbier and clumsier still, until she could barely move them. It made sense, dogs weren’t known for using fingers. Nor were they known for resisting their impulses.

Without her hands to tease herself with, she had to resort to acting more canine, which meant… The girl whimpered, licking at her lips. Unlike the others, her tongue didn’t seem to have changed. Her hips and her back, though, were beginning to shift to something completely canine.

Her back cracked and popped, and she looked down to her pussy, falling flat on her ass. A tail snaked out from her backside, long and covered in black fur. She wagged it against the floor, lowering her head to her sex and trailing her human tongue along her darkening folds.

It was amazing, better than anything she’d had in her life before. The girl had never been eaten out, and to do it herself like this was exhilarating. She could feel her teeth sharpening in her mouth, and she leaned down to her sex, lapping at it harder and harder.

Dark fur cascaded from her pores, and she was soon covered from head to toe in midnight black. It only made her hotter and hotter still, and the pleasure grew as she pressed her wet nose hard to her clit. It sent waves of bliss running through her body, and the girl whimpered in absolute ecstasy just like a dog.

“You remind me just like her, Mia. Just a dumb, Black Labrador Retriever, with her muzzle buried in her pussy. I’m sure you’ll be a good dog, just like her.”

Mira couldn’t spare the effort to be insulted. Instead, she could only lick at herself harder and harder, whimpering as her pleasure seemed to increase tenfold. It was finally happening: her face was beginning to stretch into a muzzle and her tongue was beginning to expand.

She shoved its hot wet length into her as deeply as she could, turning her head and rubbing her whiskered snout against her lips. Her clit seemed to swell with her changing sex, and she whimpered with absolute ecstasy.

Then, finally, she came. The last of her human features were overwritten by the countenance of a canine, and her black hair shed from her head.

Casey looked on in awe of her powers, a slow smile dawning on her face. “Wow… This is… This is something else.” She smirked, turning towards Martin. “So, now that your bitches have been made… What’s next?”
