be anthro dude
like to go on nature walks
even with macros in the woods
start to regret that after some feint thuds stop
then ominously start back at a quicker pace
getting louder with each Thud
you're already hiding under a fallen tree when her footfalls are loud crashes
a red squirrel woman, so large that her hand could easily wrap around you
she's kneeling down and using her razor-sharp senses to scan for you
the tree is easily thrown into the sky
she belts a "HA!" that stuns and deafens you
you're effortlessly swept up in that hand
feel your feet dangling under her pinky while your head thrashes
it's harder for her to keep her arm in the air than it is to keep you in her grip
she patiently lets you tire yourself out before thoughtfully lowering her voice
to talk like a ditz about how adorable of a fuck toy you are
she's actually gentle and quiet enough to be max comfy as she strolls to her grove
she even uses her thumb to stroke your head
then you're precisely stripped naked and massaged until you're putty in her hands
meanwhile, she's parting her dripping wet lips
you can only take a deep breath as you're stuffed feet-first all the way into her womb
can barely get your bearings but you're not going out like this
start to claw your way back out and dig into her g-spot along the way
she crashes into the ground from ecstasy and helplessly moans at your struggle
by the time you pop out and gasp for air, she's gasping with you
but she's able to slide her finger in with you and your dick's pressed firmly into her g-spot
and a curl of that finger forces your mouth onto her button
you can't believe you're getting into this, but you're rock hard
so much that you cum just as she's squirting you out
you can't really tell if her deafening squeal or flying through the air was worse
but she picks you up and sneers
she planned to fish you out and release you, but she knows when she has a keeper
you're plopped on a ledge
you'd protest, but you're exhausted from giving her seconds
you try to get some rest, but you slowly feel like you're on fire
your entire body aches and you're even in pain
it's takes everything to simply think
on the fact you just caught something from a giantess keeping you as a pet
you dose in and out for a couple hours
it feels like it takes everything you have to look over at a large puddle of water
then everything to drag yourself to it to cool yourself off
you heave yourself onto your hands and stop
the you in the puddle is a much bigger, beefier you
you don't remember your traps and shoulders being so big
but finally looking at yourself reveals thickly corded arms and legs
your pecs became dinner plates you have to look over to see a brick road for abs
and your junk is larger than what you claimed it was online
the shock's enough to ignore your aches and stand up
and the ground gets farther away than it should
you're pulled away from thinking about what's happening to you by a loud yawn
and a massive, fuzzy hand wrapping around your body
then briefly drop you in confusion before you're pulled down
the squirrel macro is outright dumbfounded as you're spilling out of her hand
you gather that the countless furs she's played with hasn't started to turn macro
especially from how excited and happy she is in how your growth is tickling her palm
she smiles and licks her chops from getting an idea
and you're dropped dick-first on her tongue before she closes her mouth
she shifts you around and enjoys the subtle shifts and changes if your growing form
your mind is being blown by the most overwhelming bj of your life
she almost chokes from how much you dump into her mouth
which only makes her laugh at full volume
you're more concerned it didn't hurt your ears than her volume
she gently drops you back on your ledge and leaves
you do feel better now
and when she gets back hours later, she grins
she looks... smaller
this time, she needs both her hands to pick you up
you're tossed and turned around, but you can actually put up a little fight
and she only needs a thumb to rub you hard and cream on it
which she licks before rubbing herself wet and grinding you into her slit
except this time, you're enthusiastically into pleasing her
and you can feel how powerful you've become, how easy she is to push and pull now
you don't have any real problem making her moan and cry in joy with your arms and tongue
and when you're done making her pant and giggle, she's burying you in her chest with a smile
the two of you talk a bit and laugh together before she puts you away
she giggles a "grow for me" before a cute yawn and curling up
which is exactly what you did, not like you had a choice
the next few days follows a cycle
you're pulled down from a ledge that's less of a home and more of a shelf
please her less like a plaything and more like a mate
and left alone to get bigger and stronger for the next go
you quickly become big enough to escape your ledge to explore
she was amazed when you were thigh-high to her and able to leap into her arms
and only a day later, you could easily poke her firm, tight belly to make her giggle
then the next day, you were a mighty macro yourself, strong enough to tackle her into an earthquake
but not mighty enough to resist her squeezing your chest-high head between her massive breasts and shake them
tomorrow saw you easily pick her up in a hug to her belting out laughter as your paws sink into the earth
then her thrusting her hips into your chin to send you both crashing down, flattening trees
you would have cared about the earthquake if hadn't lost count of how many you made after rolling her on her back
in the afterglow you thought about how you had "normal" sex with an anthro who engulfed most of you in her hand days ago
and now she's staring at you with lidded eyes and a loving smile
she fell asleep using you as a bed
your squirrel awoke in disbelief the next morning
overnight, the tables turned on her as you grew just a smidge taller than her
she meticulously ran her fingers over your now-larger muscles and organs enough to wake you
when the two of you stood, you playfully teased her about the height difference
which only grew along with your strength and vitality through the day
by the night, you were a head taller than her
but she says that subtle shifting larger is gone after some earth-shaking cuddling
you give her a soft kiss but knowing how big you really are makes her insatiable
you devastate her with every ounce of power you can give
it makes her roar out in joy when she orgasms
her walls crushing you causes your own climax and you show her how to fucking roar
you sit up and bathe in the full moon and she just studies every feature of her new mate
and after rolling over, she crawls on you, kisses you not long enough, and uses your pecs as pillows
the next day, you playfully push her around
and bask in the fact you're now bigger, stronger, and tougher than her
so much that she's now powerless in your embrace for a change
you can't help but grin, and she can't help but join you
within days, you have embraced being a macro with no problems
chalking your growth spell up to being some power you always had and she just brought it out
and she's delighted to show you all the big and small things about being big
like the fact you can take and do what you want provided anti-macro weapons aren't around
which is how you introduced your mate to beer by stealing a tanker and thanking the driver
you even managed to steal a pair of Amy Schumer's underwear before they were worn
you developed that macro disinterest in clothes but she thinks they're cute
so you kept them as a way to butter her up into a pre-sex romp
what's surprising was they were a size small on you
what's more surprising is she asked you to put them on today
your mate is a loving ditz of a red squirrel, but she's been plotting
it started over a month ago when she brought home a plaything
a little vixen who she wanted to be a itty-bitty third party that night
she thought you'd hesitate, but a tiny made you nostalgic and eager
last thing you said before shoving the vixen in your mate's slit was "you don't know how lucky you are"
her tiny got squished between the top of your shaft and her g-spot
and while you were both a little rough on the poor thing, she managed to walk it off
and after a quiet bath in a puddle, the vixen dressed herself and you carried her to camp
you and your squirrel laughed your asses off at what happened
so both of you were stunned silent when that vixen appeared and asked to be a willing party this time
turns out her awakening wasn't as much as transformative like yours, just sexual
but she did find a few kilotons of friends to visit
and let slip that the town she lives in has on defenses against macros, just sirens
and your mate is proudly telling you they test them once a month at noon
this month's is in less than an hour and she's timed it
so they're going off as the two of you thunder into the town's limits
with the "false alarm" masking your footfalls, you find a crowd before it can scatter
admittedly, you're unsure as a squirrelly hand manages to gather a half-dozen anthros
she giggles as you pull your tight briefs open at her command
with a "WHEEE!", she loosens her grip and they begin to tumble onto the reinforced fabric
a couple of them desperately cling to her strong digits, but her natural motions are too much for them
after a valiant attempt to hold onto her thumb's fur, the last one tumbles into your sack
you let the elastic go and seal them in, unconvinced
then their squirming gets you right into it
especially with her hand massaging everything to her lidded eyes and knowing grin
you smile to the knowledge that you're the luckiest bastard ever
