Smiles and squirrelsnuggles to the firm tum of a pregbatty, lets his heartbeat soothe her ears.
I know it's late. You doing good?

Fieron
yeah i'm doing good, sorry i was in the middle of something
the pregbat snuggles in return, listening to the squirrel's corruptive heartbeat, which quickly makes her even more pregnant with extra breasts and heads and arms

Balros & Echoen
He so loves the feel of her warm, plush body growing taut with pressure, a tightness like rising blood pressure that fattens veins and fills out curves. While his heart thump-thumps a steady rythm, he feels her body pulse and grow, creaking with tense mutations and constant, involuntary orgasms. Sweet squirrel purrs start up when her mutating arms grab him and pull him close against her huge breasts, shoving more taut pregnant bellies against his body.

the mutated bats pant and moan as they constantly cum and throb in time with the squirrel's heartbeat, nipples soon turning into massive throbbing cocks and muzzles, noses getting bigger, butts getting bigger, all throbbing in synch with the squirrel, building up more pressure and constant orgasms rock their bodies, birthing full grown laylees in time with each beat which also grow and get bigger, fucking eachother

Balros & Echoen
Every orgasm that erupts through the corrupted Laylee feels hotter, more potent, more productive than the last. Balls refilling and refueling and fattening larger with each time they're drained. The potency of her cum increasing rampantly, causing bellies to fatten with fuckneedy and cumming herm bats nearby. Balros gleefully nuzzles and smooches alongside a transforming muzzle-teat, helping it cum hard from both its snootcock and tonguecock. His own tremendous, aching cock throbs against that hugely plush and growing batty ass, teasingly grinding in - until a plush Laylee is birthed right onto his shaft, squelching herself alll the way down to the root of his cock. His pumping hips thrust her up against her mother's huge balls and butt, the Laylees breeding to make each other bigger.
Yooka walks in, only to get splashed with some of Laylee's seed. The chameleon groans as his crotch bulges out into a large Yooka head, nose inflating with throbbing, aching cock-shape. He tries to wipe her seed off of him but his arms turn purple and begin to swell with breasts, heads and arms of their own, Laylees that swiftly show off their growing bellies. Yooka shudders and his eyes roll up in his head as his pregnant bat-arms force their offspring up his arms and into his own belly... his forearms and shoulders stretch around the shape of busty herm bats pushing up his limbs and into a belly, where they start to fuck each other and inflate him pregnantly. The chameleon's crotch-head grows in size and takes over his body, forcing him to walk over to Laylee and the squirrel.

the newly birthed Laylee moans as her entire body is stretched all around that pulsing squirrel shaft, her own body squeezethrobbing all around that shaft, wanting to become massively pregnant with your seed, the thought instantly causes fully grown laylee herms grow into existance, which they rub and lick all over the massive squirrel shaft, hoping to make it even bigger with their lust and intentions.  They clones are already cumming hard just from feeling the squirrel's hot shaft, causing their mother's stomach to distent further and beat like a heart.
The yooka shaft looks on in awe then soon throbs violently, growing out further and forming an upper body which hugs against the laylee's hot self cum inflated belly, its body throbbing and pulsating with excitement, then cum drooling thickly from his maw and nose, veins getting thicker along his body.  Soon the yooka begins to birth hybrid lizardbats which are 10 times more potent, fertile and bigger than the others and are soon breeding themselves into the mix, the horny bunch still being affected by the squirrel's heartbeat, all of them throbbing in time with it

Balros & Echoen
There's less and less room as fuckbreeding runs rampant, more and more bats, lizards, and their hybrid progeny pushing out into the room, growing rampantly, and making more of themselves. The squirrel's powerful heartbeat dominate the soundwaves, forcing growth and mutations into anyone that hears it. The hybrid Yooka-Laylees grow with uncontrollable speed, becoming massively curvy, hyper-swollen, and urgently cumming hard.
