'A couple adopts an endangered species, not realizing just how much of an investment is required.'

Been doing an annual winter transformation story the past couple of years to mix it up, and here's the latest addition!

Human to anthro mice.


“Didn't I tell you not to get me anything?" Lucy asked. From the couch, she saw her husband, Paul, in the kitchen doorway.

Holding a fancy giftbag, Paul tilted his head and smiled. “I believe your exact words were 'you don't HAVE to."

“Always looking for loopholes, mm?" Being an accountant, she supposed it came naturally to him.

“It's your birthday!" Paul exclaimed, as if she were unaware. “Your first birthday since we got married. That deserves something. Besides, I've watched enough sitcoms to know that 'don't get me anything' is universal code for 'surprise me'."

“Yeah, and how's that normally end on TV?"

“After a comical misunderstanding, some 'ooh's' and a big kiss."

“You're such a geek," Lucy teased, unable to hide a smile.

“Just be glad I didn't have the staff sing 'Happy Birthday' to you at the restaurant." They'd just come back from a nice dinner.

Lucy watched her husband swing his arm, making the bag move back and forth. He's trying to draw my attention to it.

“Alright, I'll bite," she said, shrugging her shoulders and placing her hands in her lap. “What is it?"

Paul smiled at her reaction, pulling out—

“A bag within a bag?"

“It's that handbag you were looking at," Paul said.

“Otherwise known as a purse."

“A designer purse," he emphasized. North of one hundred fifty bucks. “You'd been dropping hints."

“For Christmas," Lucy emphasized.

“Well, you'll just have to redo your Christmas list!" He walked into the room and sat beside her on the couch, handing the purse over to her.

“Heh." Lucy smiled, cheeks getting hot. She had really wanted it. “Thanks."

“There's one more thing," Paul said. “Inside."

She opened it and found an envelope. “A birthday card?"

“Read it."

She did so, removing the card from the envelope and reading it aloud.

“Congratulations! You (or someone on your behalf) has adopted an endangered species! At 'Save-A-Species,' we gather contributions from all over the world and direct them toward areas of ecological and biological need.

“Included is a password which will allow you special access to non-intrusive webcams in the habitat of your chosen animal. We'll also send you occasional electronic updates as to how your donation is being put to use."

Lucy smiled. “That's kinda neat." She did like wild animals. She also owned more plushies than was rational for a woman of her age.

“I hope you like the one I chose for you," he said, urging her to read on.

“The species you've adopted is the … Jaliscan spiny pocket mouse. Ja … Jaliscan? Am I saying that right?"

“I think so."

Lucy continued to read:

“Endemic to southeast Mexico, this brightly colored mouse is relatively large for its genus, averaging over five inches in head-body length." She paused Does that include the tail? “Fur is reddish brown on the backs and flanks, softer beneath … " She skipped over the rest. “Never even heard of a spiny mouse before! Makes me think of a cuter porcupine."

“I'm sure everyone adopts the bigger, 'name brand' species. I wanted something unique for you. Besides," Paul added, “I know you like cute, little critters."

She laughed brightly, looking at the high-quality glossy photo of this 'spiny' mouse. “It's adorable." Putting the photo down, she turned and hugged her husband. “Thanks."

“No problem. Happy birthday, sweetie," he replied, giving her a soft lip-kiss. “Also, I got cupcakes from that place you like!"

That's why he was adamant we skip dessert at the restaurant.

Getting up and going back into the kitchen, he returned with a pink box. Setting it down on the coffee table in front of the couch, he opened it wide. There were six cupcakes. Half vanilla, half lemon. The icing on top was intricately swirled, topped with sprinkles. And Lucy knew from experience that there was a cream filling on the inside. And they were hefty, too. Nothing dinky about these cupcakes. All decadence.

Picking up a vanilla, she gently peeled the baking cup off the bottom and took a bite. Crumbs tumbled about. “Mm!" She chewed and then pointed. “Hey, we should check this webcam thing," she said, fishing for the 'Save-a-Species' sheet.

“Sure," Paul said, fetching his laptop.

When he returned, he brought up the website and input Lucy's access code. It took them to the right address, but—

“That's weird," Paul said, tapping his fingers on the touchscreen. “Won't load. Just got this … circle thing going round and round." As he waited for it to load, he indulged in a cupcake as well. He chose the lemon flavor.

“I bet we're the first ones to adopt this species," Lucy reasoned. “It can't be super popular. They probably have the cam turned off to save costs? Or maybe it's down for maintenance."

“Maybe." Paul nodded. “I'll get in touch with them tomorrow, make sure they turn it back on."

“M'kay," she said, already finishing her cupcake and trying to talk herself out of having a second. So good! She saw Paul gazing at her. “What? Do I have icing on my face?" She wiped at her lips with a hand.

“I bet you taste like vanilla," was all he said.

She smiled. “Would you like to find out?"

“Wanna go to the bedroom?" he asked softly, knowing full well where this was going to lead. He put the remainder of his cupcake (and her new purse) on the table.

“Mm." She shook her head. “No. Let's stay here." It's my birthday. Live a little!

Boy, if having sex on the couch is 'living,' then I need some new life experiences …

As Paul leaned in for a kiss, Lucy hiccupped, resulting in a high-pitched squeaking noise. She blushed. “Sorry … don't know where that came from." _ _

“Cute." Paul mumbled against her chin, “You probably ate too fast." He kissed the corner of her mouth, sucking his way into a full-on lip-lock. A hand reached up to comb through her hair. Between kisses, his other hand slipped beyond the hem of her pants. “But I'll eat you slowly … "

Lucy felt her pulse quicken. He was rubbing her clit through her panties. His fingers curled, feigning as if they were going to penetrate her. But her panties were in the way. Arching in place, she sighed and sought to remove any and all obstacles.

“Good girl," he cooed as she began to strip.

She blushed submissively.

Paul raised his arms, pulling his shirt off. His wasn't ripped by any means, but his chest had enough definition to it that she always enjoyed touching it, running her hands up and down, all around.

Maybe we should've gone to the bedroom after all.

But it was too late for that. Clothes were dropping, being tossed. Soon, they were naked, hugging and kissing with passionate intensity.

Paul reached down to rub at her pussy, and then—

Wait, he stopped … why's he hesitating?

“You, uh … Lucy?"

“Yeah?" she emphasized, voice spiking with need.

Paul withdrew his hand and peered between her legs, at a loss for words.

Blinking, she frowned, sat up straighter, and looked down with him at—

“Your clit!" Paul finally blurted.

“Whoa," Lucy said incredulously. Her clit looked big, like it was swollen or something. Not with normal arousal, either. It was growing before her eyes, extending further and further from her body!

Paul, suddenly flushed, asked, “Do you feel a bit … I don't know, funny?"

“Do I feel funny?" she echoed. “My clit is the size of a pickle!"

“No, but I feel really funny. A little dizzy … y'know … "

Lucy squinted. “Did you put weed in those cupcakes? Are we high or something?"

“These were made before I bought them! How could I?"

“You could've replaced the icing."

“Like you wouldn't have noticed?"

“Well, they had to have been spiked with something," she said. Cause this wasn't really happening. Was it … ?

“Why would anyone waste their stash on a stranger? Besides, this is too vivid … that's too real!" he said, pointing at her genitals. The tip of her clit reformed. It was starting to look like … well, not like. It was a penis. Head, shaft, and everything. All that was missing were the balls.

Before Lucy could make further sense of the situation, she grunted as she felt her bones creaking. Her skeleton! Something was happening to it. Things were shortening, lengthening. Rearranging. Organs were changing. Her heart began to race! And not in the aroused way of before. This was pure adrenaline.

“Ugh … oh, I do feel different," Paul groaned. Whatever was happening to her was happening to him, too. Looking between his own legs, he yelped at what he saw.

“It's getting smaller!" Lucy noticed, of her husband's cock.

“It's n-not … not that small," he defended with an embarrassed squeak. Wait, why was he squeaking? He covered his mouth with a hand.

“Well, mine's bigger," Lucy said, impulsively thrusting her hips toward him. Her clit-turned-penis dangled, ticking ever-upward.

Paul's balls began to shrink. At the same time, bulges formed below Lucy's new penis. Testicles. His wife was growing testicles?

“Oh, no … no," he said, pleadingly. “No … "

Lucy watched, rapt, as her husband's balls were absorbed into his body, completely vanishing, a slit forming in their wake. A fully formed vulva. What used to be his cock? Was now his clit.

“Wow," Lucy whispered, her throat suddenly dry. Was it wrong that all of this was turning her on? I never realized I was this kinky!

With Paul's shirt off, Lucy could see … breasts? They were developing on that once-masculine chest. Meanwhile, Lucy's own breasts were practically gone!

“You're becoming a girl! And I'm … I'm turning into a guy!"

“No fucking kidding," Paul replied, not sounding nearly as excited as her. Or him? He, or she, whimpered helplessly as his reproductive tract was reformed inside her. The testosterone in her blood was replaced with estrogen. “I don't want to be a girl," she said, almost pleading, as if Lucy had any power to stop it. Her voice was much higher and lighter now.

“What's wrong with being a girl?" Lucy asked, his own voice getting deeper.

“Nothing! I like girls … as a guy."

“I don't see the difference."

“Hello?!" Paul said, gesturing wildly at herself.

“No, I meant, desire is a fluid—"

“Lucy!"

Paul seemed so delicate, sensitive, and vulnerable.

Oh, man. Paul's the submissive one, now. I feel kinda dominant. Mm. Hot …

Control yourself, Lucy!

This should be freaking you out.

Yes, it should've.

Also, Lucy … didn't quite fit? Not anymore.

Luca.

She was Luca, now. Yes. And Paul was … Pauline! That sounded better. Much better.

Pauline made that squeaking noise again.

Seconds later, an ocean of fur sprouted across her skin in a quick wave, like grass on a lawn growing overtime. Poof! She was fluffy. Just like that.

Same thing happened to Luca. Bright, reddish-brown fur on his back and sides, white on his abdomen.

The fur didn't extend to their hands and feet. Those remained flesh. Tails, too. Cause they had tails now! Ropy, fleshy, whipping tails. The changes were happening too fast to keep up with. Faces became pointier, buckteeth protruding. Maws, paws, claws!

Luca saw a layer of stiff, spiky fur grow atop the soft pelt Pauline now possessed. Not on her belly. Just on his back. Almost like spines. Almost like—

“Ooh, Pauline!"

“Y-yeah?"

“We're becoming the species we adopted! Those spiny mice!"

“This isn't a good thing, Lucy."

“Luca," she corrected sternly.

“L-Luca … we can't let this happen. We need help!"

“Too late for that, isn't it?" Luca took a deep breath. “Mmm … I think it's done? I feel complete. What a rush!"

“Luca," Pauline pleaded again, her whiskers twitching.

“Hey, at least we ended up humanoid and not feral," he told her.

Pauline rubbed her newly furry face with her mousey paws, trying to concentrate, trying to figure a way out of this. But it was so hard! Something was distracting her. Something deep inside. Something that made her hot all over, out of breath even though she hadn't been doing anything.

Luca sniffed. “You … you have a scent," he noticed.

Panting, her body looking so gorgeously demure, Paul insisted, “I don't smell anything … "

“You're giving off a scent, alright. Mm … mmm!" Luca sniffed, his whiskers stiffening. “It's so … spicy." He didn't know how else to explain it, or even what it meant. But he really liked it. It was affecting his judgment. Almost like he was tipsy or something. Talk about getting high! _ _

“We need to stop and think about this," Pauline said.

“I am," Luca replied, reaching for one of her breasts.

Pauline's tail lightly whipped at Luca's wrist. “Not this-this. This … situation!"

Luca sighed and crossed his arms.

“We started changing when we entered that access code," Pauline said. “Maybe we can enter it again to change back?"

“Mm?" Luca went.

“We need to get back on the website," Pauline enunciated, growing increasingly frustrated. But, again, there was something else … gnawing at her, deeply. An itch that screamed to be scratched.

“It'll still be there later … and don't tell me," the male mouse whispered, a paw caressing the doe's chin. “That you're not the horniest you've ever been."

“W-wha … " Paul's breasts rose and fell as she struggled to control her breathing. It dawned on her, then. “I … I think—"

“Spit it out," Luca murred.

“I think I'm in heat?"

“Fertile. Yes. I can sense it." He squeaked lowly. “Don't worry, I'm on birth control."

Were," Pauline reminded. “You're male, now."

“Oh. Heh, right!"

“We aren't seriously talking about … doing it? As spiny mice?"

“Your spines are beautiful," Luca said, stroking a paw down his mate's back. Wife was such a human term. Mate. That's what Pauline was.

“S-stop it … you're just saying that."

“I'm not. And those big, dishy ears? I want to nibble on them. They look sensitive. Should we find out?"

“Luca!"

“There are condoms in the house. From, uh … a few months ago?" They always kept some around 'just in case.'

“Yeah, but they're designed to fit human dicks, not … whatever that shape is," she said, nodding at Luca's erection. It had a gravity to it. Even when Pauline wasn't looking at it, it pulled at her thoughts. Just knowing it was there made her wet.

Luca crossed his arms. “Are you making fun of my dick?"

“No," she insisted.

“Good." He started to grope at her. “Cause I can tell you want it. And, you'll be happy to know, it wants you, too."

Pauline squeaked! They were both fighting a losing battle against instincts more powerful than they'd had as humans. “But if you c-can't use protection … "

Luca gave her a bucktoothed grin. “Afraid of getting pregnant?"

“Uh, yeah!" she insisted emphatically.

“That's cute." He traced his claws over Pauline's new figure. Curvier, more petite. Such pretty fur. Such twitchy whiskers. “But you've told me you want to have a family someday?"

“I do. With you."

“Yeah." Luca nodded. “I'm still me. You're you."

“But we're not!"

“Pauline," he said, getting tired of this. He traced the other mouse's ears. “We came to the couch to fuck. Remember?"

“Did we?" Pauline shivered and squeaked. Oh, her ears were sensitive.

“Whose birthday is it?" Luca whispered lowly.

The female spiny pocket mouse looked up submissively, squeaking, “Yours?"

Luca nodded. “Mm-hmm. This whole mouse thing was your gift to me."

“Yeah, but it was harmless! It wasn't supposed to result in … in … ah!" Pauline squirmed, jaw dropping as Luca rubbed at her clit.

“Bet you wish you'd had one of those all along, mm?"

“Ah, ah, we … we s-shouldn't … "

“That's what makes it fun." Luca grinned, testing his mate's new submissive streak. “Now, lean back."

Pauline obeyed.

“Spread your legs … "

Pauline tried to keep them closed, but she opened them. It felt right. It felt like what she wanted. But she didn't! But she did? The mouse was so confused!

“Good girl," Luca cooed, standing up and moving to the arm of the couch. Gripping the doe's hips, he pulled her to the armrest, rubbing the tip of his stiff cock against her hot, silken pussy. Their bodies perpendicular, he couldn't wait any longer. It was his birthday! Luca thrust! Firmly, once, to an immediate hilt.

Pauline squeaked, eyes boggling!

“Oh, oh … hoo … that's good," Luca huffed. “Y-you … you never told me," he panted, pulling back so he could do it again, “it felt like this."

“Oh!" was all Pauline could manage. “Please … "

“Please … " Luca started to hump the mouse girl, big, fuzzy rodent balls audibly slapping against her. “Please what? Stop? You want me to … stop?" he huffed.

Pauline knew she should say yes. She wasn't really a girl, let alone a mouse. Was she? Even if she was, she didn't want to have pups! Or whatever mouse babies were called. But, oh, being filled with a cock, with her mate's cock, having it slide in and out of her? The way it reached so deep inside her body, stimulating her in ways she never could've imagined? And her clit! Oh, her clit …

“Would be a shame to feel this much of being a girl … and not get to orgasm as one," Luca teased.

Pauline's ears flushed.

“But, if you want, I can just pull out and we'll settle down instead." Luca let his erection leave the doe's body. It bobbled upright, pulsing with blood, glistening with Pauline's juices.

Pauline whimpered pitifully, reaching for Luca with both of her paws.

“Mm?"

“I … I n-need … "

“Say it." When Pauline faltered, Luca supplied, “You need to be bred."

“I need to be bred … "

“And I need to breed you," Luca insisted, reentering her pussy. “Ooh … oh, you're so wet. And hot!"

Luca humped, rutted, hammered at the female mouse. Slick, slap, slap! He wanted to last longer, but the sensations were so powerful and new. He was weakening already. Burying in his mate's clenching vagina, Luca's penis was suddenly tingling. Not a little. A lot! He didn't want to move. His whole body was tensing up! And he knew. He just knew he was going to lose it.

“Ah, ah! HAH!" Luca moaned, ejaculating for the very first time. He gasped. “Ahhh … "

Pauline whined beneath him, wriggling desperately. “L-luca, I … I think I'm … I'm! I'm!" Her body arched, wracked by muscular spasms. She was actually having her second orgasm. The pleasure came at her in endless, crashing waves! She was overcome with blinding bliss, barely able to breathe.

“Oh … Pauline … hah!" As they were both descending from their highs, Luca pulled out of her. “Damn. Best birthday present ever. Like, it's not even close."

The doe looked dazed. “Y-you're welcome … "

“Heh. We should get on the computer, I guess. See if we can reverse all this." Luca sat back down on the couch, next to his mate again. He grabbed his laptop off the coffee table. Tap-a-tap-a. “Hmm … "

Pauline sat up, breasts jiggling with the movement. “You getting that blank screen again?"

“Uh, no … "

“What's wrong?"

Luca swiveled to laptop to face Pauline.

The doe gulped. “Did … did you turn on the—"

“No. I didn't. I swear," Luca promised urgently, tapping at the screen.

A dialogue box popped up. It said:

'Welcome! You are observing spiny pocket mice in their natural habitat.'

Pauline's whiskers quivered. “But … but we're not really mice. This isn't a habitat! Who … who's watching us right now?"

Luca found the stat-line and said, “Seven hundred forty-nine viewers."

“Seriously?!" Pauline's ears went rosy-red with embarrassment. She hugged herself to hide her breasts, clamping her thighs shut to hide the mess Luca had left. “When are we going to change back?"

“How do I know? You're the one that subscribed to this. Mommy should've read the fine print," Luca accused.

“Daddy shouldn't have made me into a mommy," Pauline shot back.

Luca smirked. “You know you liked it."

Pauline's eyes darted.

They sat for a moment, quiet as the mice they were, considering their next moves.

“We could do nothing? Just … you know, lay low. Maybe it'll wear off?" Luca said.

“And if it doesn't?"

“Well, it is Save-A-Species. And there's only one way to do that," Luca whispered huskily. Whatever had changed them must've supercharged their libidos, because he was already erect again. “Agreed?"

“Well." Pauline laid back, preparing to be taken all over again. How many pups was she going to have? Just one, right? She wasn't going to have twins or triplets or anything … was she? “I guess it's for a good cause … "

Luca chuckled as he laid atop his willing, needy mate, already easing inside her as he replied, “We wouldn't want to disappoint the viewers at home."
