you love your girlfriend
Sam’s a sexy rat girl, fit from parkouring almost everywhere
amazing ass, surprisingly busty
the most adorable little pink nose and smooth grey fur
sadly all tied up in a six inch tall frame, hence the parkour
she gets you off with intense, full form tugging and wrestling
and you’ve given her plenty of tongue, fingers and pinning her with your shaft back
it’s just a little awkward explaining things to family and friends
she has a condition, one in a hundred thousand anthros who’s body is sized like the base animal
giraffe girls that grow to 17ft in height, eight foot tiger amazons and three foot fox girls lead to a broad and diverse world
and anthro guys get away with one in a million somehow
you make it work, though
Sam pulls in a good wage as a model; tiny versions of bigger clothes tailored for all sizes
until one day she received a phone call about a twentieth anniversary of Final Fantasy 9 photo shoot and stage play thing
they wanted her to play, naturally, Freya Crescent
a little fur bleach and makeup and she’d look the part
the guy behind it is a major perfectionist nut job though
once he asks for someone, he’s set in hiring them, no price too high
she agreed in a heartbeat, assuming they’d researched her condition; she’s a minor local celebrity, after all
she even put in hours learning to fight with a spear; she takes her work with adorable seriousness
the outfits were already made
made for a rat woman who’s six feet tall, not six inches
”It’s fine. We shrank and grew people before,” he said over the phone
wait, what?
”I get what I want, and what I want always works.”
breaking square cube law, biologically impossible mass changes, ethical ru-
”Don’t question my methods! I’m a genius!!”
she’s sent a box a week before the shoot filled with syringes and a large bottle of ‘colossatol’
full instructions, no side effects
more research put in since that shrink pepper spray thing so mishaps are rarer
and breaking the contract will have her sued into oblivion
”Well, shit.” Sam says
you prepare the syringe, as per the instructions, which list a ‘theoretical dose’ to be adjusted until she’s six feet tall
and with a phone ready to call an ambulance, you reluctantly poke her with the needle with an adorable squeak
she pats her painfully perforated posterior, pouting, possibly preparing despite poor probability
neither of you expect anything
then she shivers
and moans and writhes on the bed
and by the long squeak and tiny squirt from her snatch, it’s not painful as you watch with amazement as Sam swells inches taller
she’s starts fingering down below and palming up high
and in a bout of jealousy, you lie down next to her and give her a helping hand as she hits a foot tall
fingers plunge into her growing and soaked passage
she’s getting louder by the second as climax is met with climax
the bed’s soaked as she hits the tenth orgasm in a minute at three feet tall
then, mercifully as you cram your face into her over-eager folds, she stops growing at four feet tall
her eyes are crossed, but as soon as you go to ask if she’s alright, her legs hook you back in and you’re having rat for lunch
and dinner
and dessert
she’s really damn strong despite how out of it she is
and it’s a surprise when she lets you go
only to flip you over, mount you, and she practices her ‘jump’ ability by bouncing on your dick, so slick yet so tight
and she helps clean your face with kisses and licks, eyes still full of lust
maybe it’s because your ‘full’ of her but you hold back cumming for a while as you take over pounding her back
you explode in her as she hits her thirty second, and final, orgasm
she finally calms down after four hours and passing out for another
she comes fully to her senses
you watch her look with wonder at a nearly normal sized world
after eating her body weight in pizza you get some proper sleep, cuddling on the sofa
she’s started to shrink overnight
one and a half feet tall and dwindling when you awoke
instructions state to wait until fully shrunk before trying again and increase dosage as needed to zero it in on six feet
in the meanwhile, you bathe together
Sam applies her fur bleach, and by the tine she’s back to six inches tall, you now have a white furred Freya lookalike as a girlfriend
the bed is cleaned and you get a rubber sheet
you expect a lot of happy little accidents
and a lot of BIG ecstatic ones too
you’ve got another injection of colossatol, slightly higher dose, ready to go
Sam wiggles her hips and shakes her ass at you, tail swaying suggestively
”Stick it in, lover. I’m ready for round two if you are.”
you respond to her dirty talk by pinning her down and giving her a good poke
and you put everything away as she shivers
but no organic squeak
just a smooth and steady growth
all the same, you snuggle her growing form
holding a kiss as she grows from one to two feet tall, enjoying the strange sensation
roaming hands and suckling her tits between two and three feet
three to four feet you spend making tender love, a gentle thrusting as you finally fit in her again
then she pushes beyond four feet
her legs, tail and arms hook around you and she suddenly climaxes despite the still budding arousal
she clings to you and begins humping like crazy as you at first struggle, then just let it happen
five feet tall, she stronger than you are by far
you cum easy enough, and you slam her against the bed and have to start pushing a hand in in her as her squeaks and screams fill the room
then with a massive gush, you’re covered in her femcum as she finally hits six feet tall
you both collapse, you flat on top of her, head buried in her tits as she holds you against her
you mumble she’s a bit busty for Freya
she laughs
two days of near constant sex, it’s nice to just talk and hug
maybe it’s a little disappointing, but you’re still exhausted from the last two days
it’s obvious that her hyper-arousal only covers crossing new sizes
you still spend the third day with Sam at six feet tall again
lots of cuddling
then practice with the wooden spear she’s been sent for her role
then she goes out and climbs all over town, revelling in climbing buildings instead of furniture
she finishes with ‘spear’ training
she doesn’t need two hands for that
you do some sheathing as well
day four comes and goes, and you ‘accidentally’ add a little too much colossatol on day five and cuddle as she grows
cuddling intensifies
Sam sprays your crotch as she rocks about and reaches six and a half feet tall and screw like rabbits to calm her down
it throws off her training, and you’re forced to swear not to so that again
she does promise to take as much as you want after the shoot
and she’s still subtly aroused by being taller than you are for the sixth day
the seventh day comes, and a phone call sends Sam staring at the colossatol bottle, then you as she answers her micro sized phone
she’s talking about her dosage, the amount she’s been using to hit her Freya size
”A-are you sure? Okay. How much!? I’m... okay, I’ll be there.”
she puts the phone down and you ask what’s wrong
”The actor playing Puck went overboard with his dosage yesterday and it’ll take too long to wear off. He’s... big.”
how big?
”Not sure, but I’ve been told to take a specific dose based on how much made me six feet, because the boss can’t reschedule so they’re making giant costumes on a rush. We’re all going big.”
what about the arousal?
”I’m taking it here and walking there as soon as the outfit is delivered. I’ll need some help keeping control.”
anything for her
”Hope you’re ready for a reversal in size...”
Sam’s a little familiar with public exposure
once during a live fashion thing, the tiny string bikini she was wearing was designed for a rail thin model against her fuller figure
snapped right at the end of the tiny runway and people got an eyeful
and she once streaked as a dare in college, climbing into the shoulder of a live news broadcast
she’s a bit apprehensive about growing into a ultra-horny rat giantess though
she keeps mumbling, “one million bucks,” beneath her breath as you prepare a full syringe
you’ve found a nearby field but you can see people watching from afar
a truck with a two shipping containers stuffed with red material finish unloading and drive away as Sam reluctantly gives you a nod
far less wiggling as she sticks out her tiny butt
you try to be as quick and professional as possible
she gasps with pain at the amount of liquid pushing into her
the smooth growth starts
then speeds up
she hits six feet in ten seconds
and her loud squeak as she violently punches past Six foot six inches
her eyes roll back and she falls to her knees as she hoses the ground with femcum
you can’t help but get hard as she forced herself to her feet and grows quicker and quicker
her pink feet cut expanding lines in the dirt that get filled with her honey
and her hands drive in as she hits ten feet tall
fifteen
twenty
she vibrates so hard it looks like an earthquake
then she outright falls on her back as she hits forty feet tall and causes a tremor for real
still spraying, still growing
you’re grabbed and plunged inside her
it’s hard to enjoy when you just know wetness, warmth and pain
but after what feels like an eternity, she pulls you free
you wipe the sticky juices from your eyes just as you get placed in her cleavage
“Shit, you okay?”
you say you’ll feel better when everything stops spinning
she’s gotta be about eighty feet tall
and the sight of her cute buck teeth hanging over you as she plants a huge kiss is something new
”Well, time for the show.”
Sam gets dressed and applies a bathtub filled with body paint on her hands, feet, nose and ears, whiting out her pink skin
within minutes, you have an eighty foot Freya
she gently picks you up and places you on her shoulder, then heads towards the venue
a light police escort clears the roads
even so, Sam's clearly worried about damaging anything
and despite her best efforts, the road surfaces crack underfoot
eventually, though, she gets out of the town and into the country, and you can see the venue
it’s a huge auditorium build just outside of town, and you can see other actors and models already, each near enough to the scale of Sam
the mad man in charge is barking at people to get in place; camera crews, set dressing is out but they make clever used of forced perspective for some shots
as fun as watching a group of giant cosplayers do their thing, Sam's too busy for the following couple of days to really give you any attention
that said, Sam really gets into her role and most of the crew dig her performance
not bad for a model amongst what were mostly actors
so you lurk about as much as you can
then you find the tent they keep the colossatol in
boxes and boxes of the stuff
so naturally you start collecting and stashing
one bottle stands out though, although it looks very similar to the others
colossotol P.C.E.
untouched, still sealed, put next to a note for sending back some pharmaceutical company
deemed 'too experimental'
mysteriously goes missing before the shoot finishes
at last, it's over, all parties head away
you and your seven foot and shrinking girlfriend head home
she's been so big for so long, it's taking a long time for her to get back to normal
so you cuddle up for another night
cuddle and gently coax her button
and she cuddles back while stroking your length
a nice, comfy, no thrills shared climax
plenty of kisses as she continues to shrink
until you both fall asleep as she hits two feet tall, snoring gently on your chest
you eye the suitcase you loaded with colossatol
tomorrow's gonna be a BIG day
"Uh... dude? You realise you just stole about a years worth of colossatol."
you tell Sam you're well aware.
"Fucking score."
she points her well proportioned for six inches tall ass at you.
"Surprise me, big boy. I did say you could use as much as you wanted."
you'd love to go ham with it, but she still wasn't super happy about being naked in public for the third time
then you see the fancy stuff, the Colossatol P.C.E
experimental growth material
Sam's phone goes off and she heads out of the room to answer it so you decide to act quick
about nine and a half foot of normal and what would be a half a foot of the new stuff to see if this stuff works the same way
you wait for Sam, which takes a while
she runs into the room with the biggest smile on her face, then climbs up you as she always does when she wants a hug
as soon as she reaches your torso, you lay back on the bed, concealing the syringe under your hand and she stands on your chin
"I'm gonna be an actress! The execs loved me as Freya and someone wants me to be Mrs. Brisby in an adaptation of Secret of Nimh!"
so she won't have to be big any more?
"Oh, don't be like that. We have a load of colossatol, and we got on just fine before we ever had it, big bo-."
her squeak of surprise as you jab her butt cuts her off
then you press the plunger and hope you don't have to make an emergency phonecall
she gasps as she begins to grow
"ooh... that's tingly for some reason. How much did you use?"
you say enough for six foot, hoping to surprise her.
which comes and... stops?
"Felt like going classic? I can dig it."
you make out with her, feeling her firm body and soft fur
you eventually let slip you did actually put a little extra in it.
she looks at you in confusion
"How much extra?"
you wonder...
twenty feet
"Then why did I sto-"
Sam shudders violently and gasps as she stretches and swells in all directions
the floor creaks and she has to bunch up to not wreck the room.
"Fuck fuck fuck!" she panics
it's clear she's afraid to move
you enjoy the moment and give her as big a kiss as you can
somewhat awkward since she's three times your size plus change
it still snaps her back to you, and she calms down
"What's happening?"
you tell her what you think; she can control it.
Sam looks at you, confused
then she goes wide eyed and shrinks at a rapid pace
once she hits three feet tall, she stops, then grows back to six feet
finally, with a pained grunt, she shrinks back to six inches
Sam grunts with effort, but nothing
just classic, tiny, sexy rat girlfriend
"I... guess it's temporary? What's the name of that stuff?"
you tell her and start setting up another syringe
it's time to experiment with the experimental
as you plunge the needle into the P.C.E stuff, you hear Sam call your name
"Rumours of a new chemical in the Colossatol line, quietly used by the special effects industry to make giant monsters in tinsel-town, have circulated...Permanency and Control Enzyme."
she rails off a news article from a hack news site, but the more she says, the more you realise they might be on to something
it mixes with colossatol and burns it up quickly, but gives size control to the user
a rising starlet went missing after abusing it, famous for being a massive bitch behind the scenes
apparently was set for a budget sequel to Honey I Shrunk the Kids
the drug was made so that, when given, it allowed permanent control over size with only a few bottles of the normal stuff afterwards
when she realised she had control, she tried to stomp on a rival actress and go on a rampage
the whole thing was covered up, but apparently the military got involved
you look at each other, then the bottle
the only question on both of your lips is what you'll do with the other forty or so bottles of colossatol
one syringe of colossatol PE coming up
and a number of the regular stuff as chasers
you'll need more needles before long and approach her awaiting ass
with the million bucks in the bank, and more on the way, you and Sam took a vacation
the old house felt a bit cramped
although she wore it like a bikini before it totally crumbled
so here you are
a rented private island
sun
sea
a beautiful rat girl who's currently eight feet tall
the two of you in an open space a thousand feet long, away from the villa
Sam squeezes your ass as you fill a large syringe of colossatol and hand it to her
"We're gonna be so raw after this," Sam giggles
you shrug and wiggle your ass at her
a prick, a warm tingly sensation
then moments later, you have the hardest erection ever
Sam's bigger and stronger than you, but you pounce at her with enough force to knock her down
and you fuck with abandon
you swell larger, and Sam keeps up as she squeaks with pleasure
you cum in seconds, but far from feel finished, a moments later, you're even harder
Sam's having to divide attention between growing to keep up and fighting through each climax
the ground starts shaking as your tongues fight for dominance
your being rough with her, but she's loving every second
and you can honestly say that you now understand the multiple orgasm thing
the beach gets drenched, the pale sands darkening from your cum and her own gushing
you aren't even aware of anything any more
just you and Sam
nothing else matters
it's getting dark by the time your brain turns back on
both of you are well over a hundred feet tall
just the sound of gentle waves lapping against your massive bodies
it's heaven
after spending a day huge, you spend a day normal
you ask Sam what size she wants to stick to
currently at six feet tall, she gives you a wink
then shrinks
"Just because I can be as big as I feel like, doesn't mean I wasn't happy with how I was, dude."
you shrug; if it makes her happy
"Yep. now lay down."
you feel her scurry along your legs and she yanks your zipper down
then wrestles your dick out
"Besides. How else do I get to have fun with a dick bigger than I am. I need my workout!"
your starlet tugs away
and you've gotta admit... it's pretty fucking amazing.
you can't believe you missed it so much
the tiniest little claws on your thickening dick
the little line of wetness as she licks you and circles your girth
and her strength as she rubs her fur over the full length of you
the pressure as she squeezes her arms and legs, occasionally standing on your balls
Sam flexing her little feet sends a tingle up your spine
with an expert pumping, locking her legs around you and running her arms up and down, you finally peak
and with a rapid climb, you watch her mount your tip as you clench and cum
she's sprayed from beneath and gets glazed like the worlds sexiest pastry
one eye covered, she looks at you with a huge smile
"You have no idea how much I missed that. Alright, your turn."
you groan about having to lick your own juices off of her.
"You've got two options, buster. You clean me like this, or you're licking every inch of me when I'm as big as the island."
tempting, but okay, fine
you take your medicine like a man and clean her off
nothing like the taste of salty, sticky you
but with that done, you settle into fondling her with your tongue
the pleasant give of her tits
the firmness of her toned body beneath the smooth fur
and the little parting lips that you can barely squeeze your tongue tip into
her writhing, squeaking, blissful form enjoying every moment of it
then a tiny spray of her femcum to help wash away your own
Sam gives you a final gift before you settle in for the night
as you fall asleep between her soft tits as she grows as big as the villa allows
a year and a half later, you're attending the Secret of Nihm remake premier
and you've gotta say, it's awesome
Sam's a natural actress
a shame they had to make her wear a suit that covered her 'best side'
but you have to admit, she looks great in dyed brown fur and a red cloak
after the showing, the standing ovation and your little turn in the spotlight as the out-of-film Mr. Brisby come and go
of course you tied the knot
though if anyone asks it's for the money
and totally not because having a girlfriend that can grow bigger than a skyscraper and shrink as her classic six inches
work lines up for her, so you're all over the place most of the time
but you make it work
after all, you only need room for one to get each other off
thanks to that, she's at her preferred, natural height a lot
and it makes those times when she's huge all the more special
like today
you're up to your shoulders in her and grasping her button for dear life
her insides are clenching you hard as her screams echo through a disused quarry
you're there 'inspecting the filming location'
you followed her everywhere anyway, so now you're part of the film crew
a geyser of cum pumps you out and she sighs with relief
"Y'know what? I could go again."
you say you need a minute
"Ah, you'll be fine."
she hands you a familiar briefcase
you chuckle and set up a syringe that'll have you pushing two hundred feet
not like you need to worry about quantity any more
Sam bought shares in the company and has a regular supply
they discontinued the P.C.E colossatol, but she's fighting to get it back
"Actually... how about we replicate the scene where I wrap myself around your dick."
you wait for her to shrink
"Nah, dude. Other way. I think you'd look good as part of the skyline."
you gulp and line up ten syringes
time for your day in the limelight

End
