.................................................................

Carrie rolls over in the double bed , and retrieves her smartphone from underneath her discarded black yoga pants on the floor . The beautiful brunette flips through a few screens before turning the phone over to you, so you can look at it. “I found this app a few months ago, and now that I know you’re interested in this stuff too, I know we can have some fun with it.”

With **** skepticism you avert your gaze from her lustful eyes, and instead look down at the phone. On the screen there is a low resolution graphic of Carrie, and a long list of different qualities. There are a whole range of attributes, like strength, intelligence, stuff like that, as well as skills, such as public speaking, tennis, and sex (which you notice that she has a very high level in). In a separate tab there are multiple personality traits, although ‘Slut’ sticks out to you like a sore thumb as it is not only turned on, but turned up to a high level.

“I already had ‘Slut’ on when I installed the app, but I turned up the intensity not long before we started going out, and well, you’ve seen what that’s done to me!" Carrie purrs seductively, before taking she her phone back from you. Her black painted finger nails fly over the clicks a few things, and suddenly you hear your phone vibrate from the nearby table.

“I just sent an invite so you can get the app too.” Carrie explains. “You’ll have full access to my body, my mind, everything. You can change my body, you can fuck with my mind, literally anything you want.”

You go grab your phone and quickly download the app, then pull it up and see she was correct: according to the app you’ve been given complete administration access to Carrie. As your eyes pour over the options, you immediately start getting ideas, but you feel that surely that this isn't real, that this is too good to be true. Perhaps Carrie has made this all up, and it is some sort of test.

Averting your gaze from your phone, and look back to Carrie, and stare intently at her, searching for wether she's being serious, or messing with you. In the time that you've been together she has demonstrated her mischievous side, and penchant for pranks on a number of occasions, and has on at least one ocassion made an ass out of you. “Are you a hundred percent sure? You’re okay with me doing whatever I want to you?”

"Within reason of course, but yes anything". Carrie nods enthusiastically, and you’re left looking at the app again, thinking of what you want to do to her. "I trust you. I'm going to the bathroom and freshen up. While I'm in there have a look, and see what tickles your fancy into turning me into your dream girl!"

With no further preamble Carrie picks up her yoga pants, turns around, and makes her way to the bathroom, exaggerating the sway of her hips, and drawing your gaze to her firm shapely behind. When the door shuts you're instantly back on the phone, and delving through the new app, and are still more than a bit sceptical that what Carrie is offering you is for real. The app allegedly could change pretty much every aspect about her physically and mentally. You find yourself wondering that if this app really worked then why hasn't she made herself the most beautiful woman in the world? Carrie is without doubt the preetiest girl you've been with, but she's on the average side of 'the hot scale' . She’s no busty blonde bombshell, Transformers era Megan Fox, or your second cousin's ridiculously stunning girlfriend Rachel, after all.

If this truly was a prank or a test of your loyalty to Carrie then you would be prepared. You begin to make two 'folders'. In the first folder you made a very small change. Something that would be noticeable if it worked, but something that Carrie wouldn't be able to badly mock you for if this one elaborate prank. In the second change folder you decide to go absolutely nuts, writing out your sickest most depraved fantasies, something that would change Carrie into a sex crazed creature absolutely devoted to you, as long as it meant her getting the pleasure that she would almost constantly craze. She would possess a body literally built for the most sinful and perverse things you could imagine.

When you finish creating each folder both times the app asks if you wanted to implement the changes straight away, but on both occasions you press on the option tab 'Don't implement now, but save for later'.

.................................................

"So then lover, what have you got for me?" Carrie purrs seductively as she enters the bedroom a few minutes later. She's wearing a lacy black bra , which show off those juicy c-cup breasts of hers, and her yoga pants of the same colour.

"This". You said simply in reply, and pressed the tab marked 'Upload and Implement folder one'.

The changes start right away Carrie gasps. Her hands instantly reach for her tits as her boobs swell a couple of sizes until they reach a mouth watering DD size. "Is that it?" Carrie asks, with an air of dissapointment that is mixed with a lustful moan as she fondles her enhanced fun bags. "I offer you the chance to make me your perfect fuck toy, and all you do is enlarge my tits? They are great, but I wanted you to go nuts. You could of at least given me a bigger ass!"

"Oh don't worry, Carrie. That was only the test run. You'll have an ass alright!" You reply with a wolfish smile as you press the tab 'Upload and Implement folder two'. This time a warning screen pops up informing you that your file has a lot of changes in it, and asks for confirmation if you wish to implement those changes. You eagerly press the confirmation tab.

"Oh that feels nice!" Carrie remarks with a moan as her tits begin to swell again, and in the mirror behind her you can see her bottom swelling in her yoga pants. You requested that her arse would become a bubble butt so perfect that even the Kardashians would be envious of her and improved booty. All the while her face transforms subtly, removing all minor perfections, blemishes, and faint frown or laughter lines, turning Carrie's already pretty face into something that would make a super model envious. Her lips fill out into lips that look like they are designed for little else other than kissing, or sucking cocks, while her already long beautiful hair lengthens down to the small of her back, and becomes even sleeker.

"Now this is more like it! These clothes are getting too tight! Looks like I'll be needing a new wardrobe to make room for these titty monsters!" Carrie remarks with an approving grin, as she removes her now too small bra, unleashing her brand new tits which finally stop at an FF-cup. Despite their huge size you've made sure that they feel natural, do not sag in the slightest and do not cause Carrie any back ache. "I can't wait to get out of my yoga pants and see my new ass. If its like my tits then I can't wait wait for you to break it... " Carrie interrupts herself as she lurches forward dizzily, before leaning on a nearby chair for support.

"Are you alright, Carrie?" You ask, putting concern into your voice, whilst trying to hide your smile, as you await for the next round of changes to occur.

"Yeah, I'm alright. Those changes must have made me dizzy momentarily. I'm feeling OK now, although there's an... tingling sensation in my nose that I can't shake. I've got an urge to sneeze". Carrie replies, her cute button nose twitching, as she tries to sneeze, but is unable to. Time and time again the sneeze builds up, but never comes, in a kind of gentle **** that will seemingly never end for her.

"Are you sure you're OK, Carrie?" You ask the newly buxom brunette after a couple of minutes of her trying in vain to alleviate the tingling sensation in her nose, a frown is plastered over her lovely face as she's stuck in the misery of a half started sneeze.

" I will be once I fucking sneeze!" Carrie grumbles irritably, blissfully unaware that her ears have taken on a pointed shape as they start to grow larger, poking free of her dark silky hair as she as she rubs her suddenly swollen looking nose. "Here it comes!" Even after Carrie's declaration it still takes the best part of a minute before her tickling sensation reaches it's peak and she finally sneezes, making a loud noise that was anything but a sneeze. "Ahhh-haaaa-eeeh-haw-heeeh-haaaaaawww!"

"What the hell...?" Carrie murmurs. While it seems that the tickling sensation she'd been experiencing is gone, a bewildered expression is left on her her newly perfect face, while a wolfish grin tugs at the corners of your lips. The sound that Carrie had just made was a high pitch nasal sound followed by a dull harsh noise that almost sounded like an animal, albeit a very feminine one. " s-something's nnaaaawwwwt right...heeeh-haaaaaawww!"

"The app works!" You whisper in satisfaction and amazement upon Carrie repeating the harsh animalistic like noise, noting there is no pretense of a sneeze this time.

"Haaaaw hee haaawww!" A nervous sound that can't mistaken for anything other than a bray fills the silence of the room. "Haaaaaw heee haaawwww!" Carrie's beautiful eyes quickly fill with embarrassment and more than mild panic as she makes the noise for third, and a fourth time in quick succession. Seemingly unable to stop making the decidedly unladylike noises she places a trembling hand to cover her mouth only to feel a pair of exaggeratedly large buck teeth. Her hand recoils in shock and she continues to let out short feminine brays as she fights a loosing battle to keep her composure.

"W-what the hell is happening to m- m-m-m-meeeeee haaaaaw hee haaaww!" Her eyes go wide as she let's out more panicked braying. "Haaaaw heee haaaaw! The f-fuck is going on? " She groans, as she tentatively pokes at her mouth with her index finger, seemingly unable to ignore the feeling of how foreign her suddenly oversized front teeth are in her mouth. It seems that it is like an itch, once she is aware of it she seemingly couldn't stop noticing how big they felt.

"Heeee haaaaaw! " Carrie can't help but to lean forward with each bray. As she focuses on the raspy animalistic noises she can't control, she fails to notice that her ears are beginning to grow even larger, and are starting to grow fur. They push outward until they stick out nearly a foot from her head, no longer human in appearance, but more resembling the long furred ears of an ass.

The hand not tentatively exploring her new teeth suddenly reaches up to the side of her head, and touches her ear. Carrie lets out a soft bray or two without seemingly even realising it, as she rubs her ear. Both ears steadily are being covered in soft looking fur as she softly caresses her ear, and it is no less than a minute passes before she freezes, and her eyes grow as big as saucers as she finally realises that there is a lot more ear than there should be. She turns around giving you a first good look at her new bubble butt in her tight yoga pants, allowing you to come to the conclusion that the app certainly delivered on giving her an ass that even the most bootylicious ghetto girl would be envious off.

A prolonged fit of braying causes you to avert your eyes from Carrie's new booty Glancing back to the mirror you can see the panic in Carrie's eyes. Her jaw drops as she catches her reflection in the window, exposing her over sized front teeth in their full glory, as she finally realises just how big her ears they have grown. How her ears are no longer human at all. How they are angled all wrong, covered in soft grayish brown fur, and stick out from under her silky brown hair.

" What the fuck! Heeeehawwwww!* In desperation Carrie grabs hold of both foot long ears with her hands, and pulls on them hard in an **** attempt to remove them from her head, but to no avail. Carrie screams in pain as the ears don't give way despite how hard she pulls on them, only for her scream to transform into the longest and loudest “Heeeehawwwww!” yet.

"John, What’s heehawwppening to meeehawww? ! Oh my geeehawwwd! I look like a freak! Heeehawww!” Carrie valiantly tries to snaps herself out of her horror, and calm herself by regulating her breathing. Instead of rapid shallow, panicked breathing she manages to take slow deep breathes, which makes her nostrils flare. Just as she begins to calm herself down her eyes soon widen again upon noticing that when she breathes her nostrils seem to stay flared, slowly stretching larger until her entire nose is much thicker than it had been previously.

"Haawww" She lets out a muffled bray, and whimpers as she tries to keep herself quiet, and figure out what's going on . She looks herself over in the mirror again, and you can see the barely controlled fear in her eyes as she takes in her big teeth, wide nose, and furry ears. "Heeeeeee haaaw hee haaaaw. I-I-I look s-so... Haaaww... I look like a....a don... haaaww heee haaw!" Carrie stops herself from finishing the word 'donkey', as if not admitting what she looked like would help her get out of her predicament. If her face wasn't already red with embarrassment it would have surely turned so now.

"A donkey, Carrie!" Your words make your transforming girlfriend look back at you over her shoulder. Her eyes are wide with fear and anger, as she realises that not only what she's becoming, that it is in fact you that is responsible for it. "You look like a donkey!" Your eyes glide down towards her magnificent yoga pants clad ass, noting that something is going down at the base of her spine. "You're not done yet though!"

"Hhh... H-help" She croaks pitifully. "Someone... help meeeeee-haaww! Heee--heelp meeeee-haaaw!?"Carrie's eyes widen with fear again, and she brays loudly, while you watch and listen to the bones in her spine shift and tug with unpleasant cracking and popping sounds. You watch Carrie lean against the nearby chair as she seems to experience another bout of dizziness. She brays in what seems to be a mixture of pain and horror as you watch the base of her spine twist and push outward in a odd lurching forward motion, as if it is being pulled by an unseen **** as it lengthens out into a new appendage with enough **** to rip through her new yoga pants like the garment is made out of wet tissue paper. Her brand new tail, while short in length, is swaying as it quickly grows not just size, but fur too. Carrie's new appendage wags frantically back and forth across her ass, tickling her heart shaped booty. In a daze the transforming girl reaches behind herself, and grabs hold of what was tickling her magnificent ass.

Like with her ears Carrie too began yanking the tail in order to get it off, only to quickly realise that she is tugging on to herself She cranes her neck to look over her right shoulder to find and a fur covered tail hanging over her huge ass. It is already big, and is growing longer still by the second. There is a tuft of hair growing at the end which matches her own hair color, and less dense gray fur on the rest of the tail.

Carrie's breathing is ragged, and she grips the arms of her chair with one arm. Her eyes are wide open with disbelief, as she struggles takes in the changes that have happened to her body, while her other hand still tentatively tugs at her new tail, which angrily swishes between her fingers, while you watch with glee through the mirror's reflection as a small bulge appears in the front of her yoga pants.

“W-ww-what the f-fuck is heehawwppening now!?” It is a long minute before Carrie becomes aware of the newest-and in your opinion most radical-part of her transformation taking place. The transforming donkey girl's right hand abandons her new tail, allowing it to swish exuberantly around behind her, and tentatively touch thr front of her yoga pants, which are being stretched tight by something in the crotch area that wasn't there a minute or so ago, and is clearly growing bigger too.

"Noo... It can't be a... a... Caaaawwwwk!?" Carrie brays fearfully as she pulls down the waistband of her yoga pants revealing that she has what looks to be a very respectable sized human looking penis and matching set of balls to go with.

"That's right, Carrie. You're not just a donkey, you're a hot Jenny, but a Jack where it counts!" You announce with a grin as you watch absolutely captivated as she tentatively touches the latest foreign appendage to her newly curvaceous body which swells larger and stiffer, quickly becoming rock hard and gaining inch after inch.

" Hhh... H-help! Help me, John.... Someone... help meeeeee-haaww! Heee--heelp meeeee-haaaw!? I don't want a caaaawwkk heeeee hawwwww!" Carrie pitiful whines turn into loud brays as the newly formed dick between her rapidly increases not just in length and girth, but it starts to change in shape, and colour too . Within a few moments it starts to match her other features better, becoming blunt tipped, with a thick ring around the middle, a mottled gray and pink color, and growing bigger than anything you've ever seen out of hentai.

When it finally stops growing Carrie's new cock is at a length and thickness that any Jack Ass would be proud to sport, for it stands at a mind boggling eighteen inches long and several inches thick. Carrie's eyes are once wide open with shock, her other transformations seemingly forgotten as she stares disbelieving at the gigantic foreign object nestled between her thighs. "This can't be heehawwppening!" The donkey dicked girl says fearfully, and brings her right hand down between her legs her to touch her gigantic length, as if to make sure that it is real. Carrie gasps and takes a sharp intake of breath as her fingers make contact caressed the somewhat silky looking skin.

Your own cock is absolutely rock hard as you watch her hand slowly trace the length of of her brand new enormous length. Soft gasps escape Carrie's lips as her curious fingers feel the firm equine shape of her donkey dick, causing it to twitch with need, and her long tail curls around her left leg.

Carrie begins trembling, and lets out a small moan despite herself as her hand gently, and then firmly grips her new dick, her fingers barely able to wrap themselves around the top of the huge thick shaft. With great trepidation Carrie's dainty hand starts to glide down the huge shaft, causing a barely stifled moan to escape her lips.

Carrie is soon moaning deeply as unfamiliar sensations **** her overwhelmed body. Her hand is now working its way up and down with much more vigour. Despite the fearful expression on her lovely face the busty brunette seems unable to stop herself from stroking her huge cock. It seems that her hand is moving like it has a mind of its own, and it is in tune with throbbing beat of the huge shaft between her legs.

"It looks like that you're enjoying that, Carrie!" You remark with a wolfish smile.

Carrie's eyes widen in surprise, and she tears her gaze away from her equine dong to look you in the eye. So lost in what she has been doing it appears that she forgot that you are still there."S-shut up.. It’s just strange feeling.. it’s not like I’m enjoying this!"

"Oh, I'm no so sure, Carrie". You reply in a teasing tone of voice, as you avert your eyes from her face to the huge cock throbbing angrily between her dainty fingers. "You seem to be enjoying stroking your new cock. Your huge.... donkey cock!"

" I'm not enjoying it! You don’t know haaaaw hard it is to- *Uhnnf* control it … it’s so heeehaaaaawt… so hawwwwwd.. I can’t... my balls are so full... please make it stop.... I… please, you have to help meeehaaaw!” Carrie takes a step forwards, and grabs hold of your wrist- with the hand not jerking herself off-with surprising strength, and pulls you in close.

"I just neehaaawd... to cum!" Carrie whimpers as she puts your hand on the massive donkey dick, just beneath her other hand. You can feel the beastly tool throbbing between your fingers. It’s almost burning hot, and the pulsing is rapid and urgent. She gives you a **** look, and you have the distinct feeling that this is the time to make her not only accept, but embrace the changes that she has just gone through.

"Do you like that? Do you like me stroking your huge donkey cock, you sexy ass?" You ask Carrie with a nasty grin, as you begin to work your wrist up and down her enormous shaft.

"You're the ass! I'm.... I'm not a donkey!" Carrie's words themselves are defiant, but they sound hollow to you , as the tone of her voice is one of arousal and confusion, and she sounds more than a little lost.

"That's right, Carrie. You're not just a donkey, you're a hot Jenny, but a mighty Jack where it counts!" You declare before planting a kiss on Carrie's luscious lips. Carrie resists your advance, and doesn't reciprocate, but you begin stroking her huge shaft with your hand at a much faster rate, making her moan loudly, allowing your tongue to slip into her mouth, and let you feel Carrie's oversized front teeth with your wet muscle. Moving on to locate Carrie's wet muscle with your tongue you place your spare hand on the hand the horny donkey-girl is using to she to stroke her huge equine shaft. It's almost certainly the best, most passionate kiss you've shared with her. As the pair of you make out you take control of the hand she is using to stroke her brand new cock, dictating the pace of her pleasure, bringing it down to a slow teasing pace.

It's not long before Carrie is unable to take the teasing any longer, and pushes away, breaking off the long tongue twirling kiss. "Please... I can't take it, I-I need to cum! "

You chuckle in satisfaction, for the moment of Carrie's new life is at hand. "What a desperately horny donkey you are, Carrie! Bray for me!"

You didn't know that it was possible, but Carrie's face turns an even brighter shade of crimson. "W-what...? no I..."

In a blur of motion you grab hold of Carrie's wrists, and secure them behind her back with one hand. The curvaceous dark haired animal girl whimpers, partially in discomfort, but mainly - in your opinion- because her huge shaft is no longer recieving any stimulation." If you want to cum, if you want any sensation whatsoever, you know what I want. Bray for me. Tell me what you are!"

Carrie's donkey-cock throbs visibly, and with a pained sigh she mutters out a feeble half hearted attempt at a bray to your disapproving glare. She tries in earnest the second time, and she let out bellowing heehaw much to your delight, so you reward her by wrapping your fingers back around the thick trunk of her cock.

"Much better, Carrie. Much better!" You say approvingly, making your transformed girlfriend bray louder in reply, and once again speed up the rate of your hand pumping up and down her equine shaft. "Do you see how much better things can be for you if you cooperate?" You feel that she's so close to embracing her new form. Her new life."What are you, Carrie?"

The transformed girl whispers something that you can't hear over wet sounds caused by your hand practically flying up and down her magnificent throbbing length. "What are you, Carrie?"

Carrie's eyes meet yours, and you can see anger, shame, and arousal mixed together in her beautiful eyes. The brunette opens her mouth, and although its extremely hard to hear, due to her speaking so quietly the words that you've been longing to hear Carrie say pass though her luscious lips."A.... a donkey".

"What was that, Carrie? Say it again, please. Louder. Tell me, and the world what you are!" You demand, your hand is almost a blur as it flys up and down her turgid length. "What are you, Carrie?"

"I'm a doneeeeehaaawww! A big dicked daaaaawwwwwnkeeeeeey!"
