It'd taken days, Millie stuffing Lily full of fast food non-stop, feeding her the delivery drivers on top of it, rubbing and kneading to help her pet churn all of that food into more wonderful, pliable fat and adding height to her frame to carry it all.
And spending the time between the deliveries fucking her senseless, making sure that the bloated behemoth of a woman never spent even a moment empty - not out of fear, but out of pure, gluttonous greed.
The mouse wasn't trying to keep a ravenous predator sated.
She was fattening up her New Year's feast.
Every inch of flesh, every wobbling pound or jiggling fold of fat was just more calories for Millie to claim.
Twenty-one feet tall, were she able to stand. She couldn't reach a scale that could handle her weight, but thirty tons would be a reasonable estimate.
Mille walks around her prize, running her fingers over Lily's soft flesh, the mouse's stomach roaring as she imagines having all of this meat stuffed into her stomach. Even now, her pet was drinking a mix of melted butter and heavy cream, pumped from a tank through a hose, making herself just that much more succulent for her gluttonmaus.
"Mmmm, it's going to take me hours to even swallow you up, pet," Millie coos, reaching up to gently rub the underside of Lily's bulging, rippling throat, "Days for me to properly digest you."
She keeps walking around, the mouse giving her pet's nipple a squeeze, licking at the thick cream. "And I can't wait to bring you back afterwards," she continues, "Let you see just how big you're going to make your mousey mistress~"
Her paws shuffle softly on the carpet, Millie walking around behind the mass that was Lily's body now. "Mnnnn, I just can't help myself," she coos, reaching up and grabbing her by the ankles, "You're just too delicious to resist any longer~"
The mouse shoves her feet into her maw, quickly gulping them into her throat before starting to drag her way up the mountain of flesh. Her jaw quickly unhinges, the gluttonmaus's flesh stretching as she inches her way forward.
Her thighs are the first real obstacle, each one nearly as big around as an oak tree. Then her ass, each cheek the size of an SUV. That alone took the mouse two full hours. Then what she knew would be the real sticking point - her gargantuan, blubbery belly.
Millie's flesh had to stretch wider and more than it ever had before, but through sheer determination over the next eight hours, she manages to swallow up every inch of soft gut, her jaws advancing on Lily's tits.
Each breast was twice as big has her ass had been, slowly swallowed up by the insatiable mouse. That left only her soft shoulders, her dozen chins, and finally, her head. An hour later, Lily was gone, her body sealed away inside the mouse, Millie lifted nearly to the ceiling by her massive, bulging stomach.
"Ohhhh, fuck," she groans, her eyes crossed in absolute bliss, "Ohhh...mmmm...you're gonna take me days to digest." Her stomach, working harder than ever before to cope with the sheer size of her meal, grumbles and groans. Her hands roam over the small patch of her belly that she can reach, before...
BHHHUUUUOPPOOORRRRRRPPPPP
The deep, roaring belch breaks windows in the mouse's home, shards of glass flying outwards as she announces her triumph to the world. After a few moments gasping for breath, sleep takes a firm hold on Millie, the mouse laying down for a long winter's nap atop her churning hill of a belly.
"Mmm, g'night Lily," she coos as she settles down, "Bring you back in the new year~"
