Glorp, glorp, glorp. The weight gain was slow. The sound was heavy, lingering in your gut as it pushed out rounder, bigger and fuller, full of fat and womb and girl. It was only a couple pounds - for now, the squirrelboy's thickbig handpaws too big to cover your mousebelly with both hands. He had to settle for just one, slipped down your hoodie sweater, your newly swelling breasts piling around his wrist. Your head was nestled into the crook of his arm, muzzle pushed to his armpit to endlessly inhale the potent squirrelmusk, addicting chemicals that made your young brain fizzle and pop with too many hormones.
With his other hand, he held onto a steering wheel, the squirrel ostensibly driving you to school. For some reason, your mousemommy had hired him as a personal driver instead of letting you take the schoolbus.

A client in more ways than one, seeing as her immediate request upon seeing you was to tie her up in the backseat while you did whatever you wanted to her daughter.
Muffled squeaks emanate from within the depths of fuzz and 'pitmusk, the glorpings becoming deeper and more aggressive the longer she's left inhaling your sharp and musky odour. Plastics groan and creak as the car seat struggles to support the massive mass of mice-within-mice CHURNING into existence, and as you turn the corner into the road with the school's drop-off point, many of her classmates are treated to the sight of mouse puss and ass SMOOSHED against the car window, seemingly engulfing more of its surface at an alarmingly increasing rate.

He glances briefly to the back seat while at a stoplight, meeting eyes with mommymouse, seeing that she too has filled up nicely from being tied up with his long 'n' floofy squirreltail wrapped around her. Her corruption was a bit of an odd one; she seemed obsessed with and getting off on not her own body, but on what happened to her sweet squeak of a daughter. Well, he wasn't going to turn down her requests!
That daughter, though, just, wow. Could there be someone so damn cute? Even as you grew and grew and grew, you managed to exhude adorability and sweet, youthful need. Your side of the car began to dip lower as you keep gaining weight, the shocks straining to hold the vehicle up by the time he pulls up to your schoolyard. The door is bending outwards as your butt 'n' puss press against it, pink petals surrounded in silky white fuzz, and a bright pink donut tailhole 'neath a large long pink mousetail. The squirrel's big paw is still sunk into the softness of your girlgut; when he pulls it away to actually try to drop you off at school, addiction withdrawel pangs begin to ache within you hard.
He looks down at your cute face, muzzle stuffed into his pits and one eye peeking out up at him. "Alright, sweetysqueak, we're here. Schooltime."

Hardly able to move in such a state, she thankfully has some help! A little mousepaw, then an arm, reaches out from her puss and moves downward, feeling around until it find the door handle...
The moment the door is opened, the cute moans turn into desperate cries as her pussy and pucker are stretched wide and bulged obscenely outward, taking up the entire frame of the doorway as they begin pumping out little mousedaughters, each of which have obscene pubic and armpit floof which radiate a sweet, musky and addictive scent from them.
The daughter of the phantmom in the car closest by is forced to watch as the AC blasts her in the face with pure floofmouse, sending her into a writhing fit as every part of her, inwards and outwards, is forced to mutate into the very same. Phantdaughter's clit beneath her skirt starts throbbing and squeakgiggling, describing in every detail how her mom's limbs and features and organs are squeaking in protest of coming into existence, and how it's all going to happen more agonisingly, deliciously slowly for herself...

Pregnant just by huffing him and touching squirrel? He's so damn potent, even mommymouse in the back seat can feel squirming fuckmice roiling in her womb. His eyebrows shoot up as he hears the door open, thinking at first you kicked the handle with your foot, but swiftly disabused of that notion as you start muffledly moaning and squeaksquealing into his floof and armpit, clearly sounds of pleasure and rampant hormones. Pressed against him as you are, your chest swells and fills out with big, bigger mousefurred breasts, flooding your hoodie with tit and smooshing his lap too. He's getting jammed into his driver's seat, the car tilting even further towards the curb...
Those mousedaughters are, well, short. Short, and plump, silky ivory fur on their bodies but with bushes of pubic and pit fur that pump with a pink mist. One girl scurries up to the front of phantmom's car and mashes her sex to the radiator, gigglesqueakmoaning as pink muskfumes pour into the car. Phantdaughter looks on with shocked horror as her bigbig phantmom mousifies - only to start moaning and squirming herself, feeling a pressure build in her panties, throbbing need pumping into her clit. She looks down only for a mouseface to look back up at her and make her cum
