(F to Cow, F to Bimbo and F to Dog)

Hannah stared unblinkingly at the image before her. It was a cow, mindlessly chewing away at a mouthful of grass and dirt. Its tail swished behind itself absently, as though there could be no greater pleasure than finding the occasional worm in its food.

And apparently…

“Hahaha! You’re a cow, Hannah!”

… it was also her.

Hannah slowly turned towards Dani, forcing a smile through a supreme effort. “So… Uh… This whole… ‘Window to the Mirror World’ thing you invented…”

Dani adjusted her glasses, blushing as though she was embarrassed on Hannah’s behalf. Somehow that made it all worse. “W-well… I mean, there’s multiple universes out there, probably. This is just the first one that we were able to see…”

“Why do you sound embarrassed? You’re practically a porn star in the other world, live it up a little!” Carrie wrapped an arm around Dani, giggling. “Besides, it’s not all bad, Hannah. I mean, I was a total dog, right?”

Hannah sniffled. “But… Like… Samoyeds are cute.”

“And some people think fatass cows are cute. Not me, obviously. They’re way better as steaks.” Carrie kept chuckling, looking back at the screen. “Come to think of it, I’m starting to see a resemblance.”

Dani hurriedly tapped a few keys on her computer, glancing up to the screen. “N-now, it’s not like this is a hundred percent accurate. Maybe there was an issue with the… Aha!”

Hannah let out a sigh of relief. This was supposed to be fun. Dani had discovered a way to view an alternate universe, so they were supposed to see what exciting lives their alternate selves led. It was decidedly not supposed to be looking at some big dumb farm animal that apparently housed Hannah’s equivalent soul.

“Hm? You found something? We’re still on a farm, so… Maybe she’s a farmer?” Carrie looked over Dani’s shoulder, realized she couldn’t make any sense over the text that was displayed, and looked back up the screen, which panned across a farm, seeking Hannah’s alternate.

The picture settled on a cow that was somehow even fatter than the first, with a calf suckling at its udder for good measure.

“O-oh. Um. Well. At least you’ll be a mother, right?” Dani really tried to cheer up her friend, somehow selecting the exact wrong words.

“The hell with this!” Hannah looked down to Dani’s keyboard. There was a button Dani had pushed earlier to ‘prove the concept of the thin space between worlds,’ where she’d made an orange in the other world into an apple from this world. It looked like…

Hannah stabbed her finger at a key, grinning. “There! Like hell I’ll just let myself be a cow in that other world!”

Carrie laughed obliviously. Dani stared in abject horror.

“Oh, spare me the science talk about how we’re supposed to ‘not interfere with other worlds’ or that junk.” Hannah folded her arms.

“N-no! You need to hold the shift key before you press that!” Dani stammered, frantically moving her hands to the keyboard. Her fingers trembled inches from it as though she was unsure what to do. “Uh… I mean… Otherwise… You… Uh…”

Her short dark hair started to lighten and lengthen at the same time. Her pale skin took on a darker hue, nearly contrasting the blonde tresses.

“Oh. Otherwise it goes the other way, huh?” Carrie tilted her head. “Hey, at least that other you looked like a lot of fun, right?”

“Other… Me?” Dani blinked repeatedly, before tearing her glasses off. She shook her head, looking up pleadingly to Carrie and Hannah. “I mean! It’s not just something you can undo! You…”

She trailed off, her hands drifting towards her chest. Her petite chest puffed up obscenely, heavy fat spilling past her hands, popping the buttons of her shirt like a tsunami plowing over a sand castle. A moan slipped past her lips, a new husky undercurrent to her breath.

“You… Uh… Hehe…” Dani’s eyes focused and unfocussed, occasional panic breaking through the vapid expression she’d picked up. “I mean… Uh… Hannah, I don’t wanna be dumb! Do something!”

“Screw being dumb, you’re totally hot now!” Carrie gave Dani an attempt at a thumbs-up. Instead, her hand remained outstretched, like she was offering Dani a handshake.

Hannah’s eyes widened as Carrie’s palm darkened, swelling up into what looked like a paw pad. Thick white fur sprouted between the enormous pads, and Carrie looked down at her own palm curiously. She turned her arm back and forth, watching as the fur advanced up towards her shoulder.

“That’s… Not good…” Hannah gulped, looking to the computer next to an undeniably dumber Dani.

“Ooh, buppy!” Dani giggled, grabbing Carrie’s hand and pressing it against her cheek. She nuzzled into it affectionately, kicking her feet back and forth like an idiot.

“Probably not. But at least I won’t be a cow.” Carrie chuckled with a wink. Her spine wrenched with a loud pop, and the girl dropped face-first into Dani’s fat tits, letting out a quick yelp of surprise.

Hannah gawped, especially as Carrie didn’t make any motion to right herself. Instead, the girl started to wag her butt, cuddling their bimbofied friend. “You… What… How are you enjoying this!?”

“Well, that’s a silly question!” Dani chirped. “Lotsa people love snuggling my boobs, duh!”

“She’s turning into a dog, you nitwit!” Hannah scrambled to the keyboard, frantically thinking of what keys might be able to undo this.

“Don’t be mean,” said Dani with a pout.

“Yuh, dunnn be mheeen,” slurred Carrie around her stretching face. Carrie’s nose had already darkened at an alarming rate, and her smile revealed sharpening canines. “Buh-bheesides… If I dhrrridn’t like it, whrruff’m I suppROOF tuh duhrooOOF!”

As the girl barked, her chest barreled out, letting the sound reach a deep baritone timber. It sounded exactly like the bark of a big, heavy dog – and yet was so much lighter than the moos Hannah dreaded might soon spill from her own lips.

“No, no, no…” Hannah fumbled with the keyboard, realizing it was already too late for her. Her fingers weren’t moving the way she wanted, clenching in towards her palms and leaving her half-punching at the keys.

“What’s the matter?” Dani tilted her head, absently scratching Cassie’s canine cheeks. Cassie grew a tail just to wag it, panting in Dani’s face. “I mean, I’ll totally take good care of the buppy, it’s fine.”

Hannah hiccupped, still struggling to deny what was about to happen to her. Her panic quickly turned to anger, and she glared at Dani. “Just say puppy! With a p!”

“But… It’s spelled with a b, isn’t it? Just like. An upside-down one that’s all packwards.” Dani giggled obliviously.

Hannah didn’t know how to reply. Her mouth moved independently of her brain, as though she might be able to somehow come upon the exact right response. “You… You… YOOOOOO!”

Her eyes widened and she cupped her hands over her mouth. It let her feel the distinctly unpleasant sensation of having her lips thicken and grow a thin layer of stubble at the same time.

“Don’t have a cow!” Dani giggled a little at Hannah’s expense, only to outright laugh at the look of disbelief Hannah followed it up with. “Just because I’m dumb doesn’t mean I don’t like puns.”

“Woof!” Carrie barked like an idiot, wagging her tail and squirming against Dani’s oversexualized body.

This was it. Hannah had seen her two best friends turn into a walking wet dream and a dog, and she was going to become a cow. … Funnily enough, knowing it was happening did not make it better.

“Gnnuuuh!” Hannah slammed her fingers against the keyboard, only succeeding in knocking some of the plastic keys loose. “Please! Stop this before I MOOO!”

“Well, probably couldn’t even do that if I tried now…” Dani muttered, looking at the keyboard with a small frown. “Pretty sure I need that to stream…”

“It’s not fair!” Hannah sobbed. “How come MMOOOO have to be a cow!”

Dani played with Carrie’s paws, looking up to Hannah with a frown. “I mean, your buddy here turned into a dog, so is being a cow really that bad?”

“Yes!” Hannah exclaimed. Her stomach gurgled and she whimpered. There was something building inside of her, a bubbling pressure that made her feel taut, claustrophobic in her own skin. She held her breath as though that might stop it, but that only made the bubbling feeling even worse.

Then, with an awful, stretching sensation, Hannah’s world turned upside-down. Her stomach stretched out and out, with so much force that it shoved her onto her fattening ass. A tail exploded from her backside, rolling Hannah onto her side with a heavy thump.

Her cheek was shoved against the carpet, and Dani felt the fuzz against her cheek as it stretched out into a cow’s muzzle. Her tongue in particular bulged unnaturally, flooding her mouth before bursting past her lips with a humiliating spray of drool.

“Oh, gross. I guess I kinda get it.” Dani muttered.

“OO gleth!?” Hannah slurred a little bit, groaning as her arms and legs slowly rotated perpendicular to her body. She really tried to keep them from moving, but the effort exhausted her to the point where she soon found herself snorting through her nose into the carpet. She couldn’t breathe around her tongue, not with her mouth at its current half-human size.

To make things even worse, a new pressure built up between her legs, a vast new balloon of flesh inflating and spreading her thighs. At the same time, an invisible vise squeezed at Hannah’s chest, flattening away her human femininity.

“Well, sure. I mean, cows are cute, but… Was that rhetorical?” Dani asked, tilting her head.

The word stuck in Hannah’s brain stubbornly. It was so familiar, yet she couldn’t quite place it. It was like years ago when she tried to learn German, because… She… Uh… Did that happen? No, it had to have happened, she wanted to… speak? Instead of mooing?

Hannah gagged around her tongue as pressure build in her head. It wasn’t painful, but it was uncomfortable, feeling things move that shouldn’t be moving. Her hooves scraped against the carpet as she tried to right herself. Instinct had her tuck her legs towards her belly and roll a little.

Her head swam with vertigo, and her ears drooped at the sensation. She wiggled them a little before feeling a bit of panic for a reason that she was having trouble understanding. Her mouth stretched out a little, just enough so she could maybe ask the person.

“Duh... Dhhuhhnee… Wha… Mrrroooo…” The cow groaned, that pressure still clogging her thoughts. What was that first not-moo she made?

“Huh? Oh, I guess you’re brain’s gonna get all,” Dani said, followed by some other not-moos that only confused the cow more.

She definitely shouldn’t panic, then. It looked like the dog (the cow was quietly proud of herself for remembering the name) was happy, and that meant there couldn’t be danger nearby. She plopped idiotically onto the ground, trying for a few moments to chew at the short grass. It was too short though, and the bites she managed were gross.

The cow huffed, looking around for grass. Her eyes focused on what looked like another cow in a field, but she didn’t smell the other cow so it had to be not real. Still, she was jealous. That cow looked like she was having such a good day.
