Balros & Echoen
Judy.
Tell me your thoughts, sweet bun. You've been having dreams.

RabidBadger
Well, I mean.. last night it was this weird thing about being adrift in a space probe with no hope of rescue but then it got into weird places where I was seeing reflections of a badger? And like.. a big one. Something felt awkward and horny about that but it's kind of fuzzy, I forget these things after I wake up preeeetty fast.

Balros & Echoen
rufflescruffles your thickfat cheeks warmly "Tell me about the emotions you felt, or feel even now about it."

RabidBadger
Reaches up and puts a paw against one of yours while looking around in mild confusion.
"W-well, I remember being confused and maybe a little scared but not about what, and then the uh.. the awkward and horny part kicked in? I don't know why that happened either but it was kind of a whole lot stronger. Like I was just.. hungry for something, or everything?

Balros & Echoen
*The bat's hands are large, motherly, soft, but Tiger-Mom strong. Somehow, everywhere you touch hir ends up thicker, fuller, softer, plumper. "It sounds like desire, undirected."

RabidBadger
And getting plumper just makes sure more things touch. There's a goodround* bit of bunny cop, looking more like someone who's been at Clawhauser's side at the front desk for a decade or so than someone on the streets for a year or two. 
That confusion is getting worse.*
"Definitely undirected, whatever it was. I think it was good, though..? I kind of wish I could just re-view it, you know? To check? But once it's gone it's gone.. I-"
A body-wide shiver runs through me, and a loud belly rumble.

Balros & Echoen
Feeling you soften, thicken, swell within hir caresses, shi is even more supportively stroking you to round you out and fill you fat. Shi helpfully perches you up on the seat that used to be Clawhauser's, but had to be enlarged for engorged bunbun butt.
"What would you most wish to find, if you were to check. Or to have another just like it?"
A wingpaw strokes your gut, making the chair creak from the weight you gain from a few seconds of hir fondling your belly.

RabidBadger
"I- I mean.. I want to know what happened in it, so - so another like it I guess? But I guess I have things I'm hoping it is too."
More bun. Just so much more bun. I reach down and try to pull my uniform over my belly but it hasn't fit over that in months, and it's not like I can even reach past my sides. Getting to the first two fat rolls is hard enough with how thick my arms are. Reaching the actual edge of the space I take up on that special chair? Ridiculous.
"L-like.. how big he was, and heavy? Dense? But never quite big enough. I- how.. do I get up, again?"

Balros & Echoen
When you reach down to grasp your uniform, you see the great girths of fat that swaddle your arms and paws. Your profoundly round gut feels so full, so dense, and protrudes from your middle at a distance further than you can reach. "Density. This is a good descriptor. Thicker in substance, even as you're huge in shape." Shi leans in, the bat's body warm against your bulk, your chair protesting as it has to deal with some of hir prodigious density, too. Hir warmth on you fuels hir words to you, feeding your weight gain all over you. "Judy, get bigger. Like that badger. Grow and cum until you're as dense and heavy as you dream him to be."

RabidBadger
Maybe it's the choice of words. Just a little twist of intent and that fantasy catches like an ember tossed into dry kindling. All that bunny starts to quiver and the tenuous grip on that belly is gone moments into the ordeal. Into the sudden deluge of bliss and juices flooding out onto the seat beneath. My eyes roll back in my head and my mouth hangs open, a slow building sound in the back of my throat turning into a resonating moan. At some point the chair just isn't enough, there's just too much bun for any such thing to suffice. A landslide of blubber in every direction, feet ensconced in layers of fat rolls that imprison them as little useless reminders of what had once been an extremity, arms not much better off. And the eyes? They look a bit on the glazed and vacant side.
Denser. All over. Through and through. And still growing, bit by bit.

Balros & Echoen
Echoen sighs in deep, rich contentment as your flame of passion flares and you begin to just, fucking, cum and cum and grow and cum. Shi relishes the decadent expression of your lidded eyes and lowered ears, open muzzle and full-throated groans. Hir ears drinking in the sounds of your rotund bunnyflab body bloating bigger, fuller, fatter, and heavier with more and more mass. The chair complains so much until it is simply flattened by fattened rabbit ass. With a THUNDERBOOM that shakes the entire precint, a million kilograms of you sits down on the floor.
But, your head and shoulders stay relatively where they were, pressed against Echoen's embrace. You've grown downwards, become massive, taking up all the space the chair's perimeter once had. Echoen croons sweetly and strokes the fat-folds of your thickening chins.
"Close your eyes and imagine the badger, Judy. Think about him and how much he will cum if he looks in a mirror and sees... you."

RabidBadger
Every fresh surge of growth seems to just add fuel for the next one. I sprawl out a little further, something breaks somewhere, a person gets flattened into the wall by bunny ass and it makes me want more. A fresh wracking orgasm sends all that flesh into a torrent of jiggling and things get slower and simpler upstairs at the same time. It's impossible not to just let your voice guide things now, to suggest where to go next. 
Another body-wide shiver, a sluggish nod of my head even with it encased in fat rolls-
"J-just never stop. Like.. ever~"

Balros & Echoen
Anyone, everyone, who gets shoved aside or smothered under billowing bunny flab soon finds themselves bucking and jerking as they start cumming too, needing and lusting for more weight and pressure to be applied upon them. A need for more of you to press against them. The bat's vocalizations reaching them through reverberations in your fat, though you bear the brunt of hir weight-gaining words.
"Make yourself fatter, Judy. For him, for your badger. Fill your fat gut even bigger so he can cum harder when he sees it." Shi pushes hir paws into your immense swell of belly. The bat's hands are pushed back by the rising roundness of your stomach, your pleasure-snuggled mind feeling your belly growing with more and more mass and fullness. The bat leans in so hir lips press close to where your ears meet your head. "Keep cumming and keep gaining, you have so much more to release from within you."
With hir power, shi has linked your orgasms to your weight gain. A positive feedback loop, feeding you more mass the more intensely you orgasm. Building as a pressure deep within you, so satisfying, so -relaxing-, to growgasm as hard as fucking possible.

RabidBadger
It's not like I can do much of anything else, is it? Even if it weren't for the absolute state those words cause. No more words come out of my mouth, just an escalating shuddering moan. A ragged noise that sings its own story of sorts. A ballad about an avalanche of fat rolls that knock down walls, of a thundering ass crack that devours an entire queue of people waiting outside the precinct, of everyone currently in lockup being imprisoned in walls of lard and fur and sweat and cum. For a few seconds of it I squeeze my little bunny hands and feet, but those vanish into thick dimples of rolls before long. It's just fat cheeks jiggling in that ragged endless moan and the orgasm that was fueling it.
