Balros & Echoen
Balros just casually makes out with the lovely calm mutated Laylee-head, while the other grow-screams into Fierons' face

Fieron
the calm laylee just wraps her arms around the squirrel, one around his back the lower grabbing firmly at the squirrel's large rump, sticking her tongue down the squirrel's throat, you can feel her tongue firming up as it's quickly turning into a cock.  Fieron not saying a word as he's a victim to the other laylee's constant verbal assault, not really making sense about what she's yelling about, watching the growth and throbbing happening on the mutated laylee's left half.  The bunderg throbbing and growing as well as she's having a considerable effect on him

Balros & Echoen
The kisses are so soft, the tastes they share between them so sweet. His arm snuggles between her two arms on that side, big wobbling bat boobs smooshed to his furry chest. Warm chrrs spill from his throat as her tongue spills down it and grows. Soon he's gulping hearty quaffs of battyherm cum, while still pressing lips and rubbing warm noses. He cuddles a bit closer - pressed to that warm dome of pregnant belly, frotting sheaths and smooshing churning balls.
While the squirrel engages on some relatively calm canoodling with that half of Laylee, the other half of her is unloading her sexual insanity upon Fieron. She almost can't talk fast enough, screaming out pleasure and ravenous lust-need for him while growing uncontrollably. She 'grips' the bunderg with her torso-arm and shoves her cocksnout-hand between his legs, nose-cumming hard against his crotch. While the calm-Laylee is just sheathfrotting with Balros, the sex-crazed bat has an enormous erection spilling out of her side of the sheath, fat with veins and visibly pounding, POUNDING with pumping pressure. Her nose creaks bigger and starts to fire hot jets of seed into Fieron's face. His chest bulges as a Laylee heart grows next to his, getting bigger than his heart and thumping with enraged lust.

Fieron
The bunderg just squirms and clutches his chest as he feels that newly formed laylee heart beating insanely fast in his chest, then groans lustfully as that heart fully assimilates with his own, making an intensely large bulge over the entire front of his torso, thudding intensely loud, causing the bunderg to quickly mutate with each heartbeat, becoming half bunderg and half purple bat.  all of that hot nose cum that covers his face and crotch, causes his nose and cock to become long and hard, beating like hearts with massive bulging veins on each, just moments before his massive cock becomes a massive purple and gold bunderg muzzle, his nose turning into a massive red laylee nose which quickly takes the shape of a MASSIVE cock which beats like a heart, the massive bulging heart suplying his boners with an intense amount of blood, making them grow with each heartbeat

Balros & Echoen
When he clutches his chest, the big bulge of his heart pushes his fingers outwards. Those digits also begin to throb, and the rest of his arms start to rapidly swell, losing control of them. His left arm becomes a busty, heavy, lustful Laylee torso, while his right arm becomes a blushing, hyper-horny and similarly busty Fieron herm. They grope and play with his massive chest as it grows tits around the bulge of his mega heart, sucking on his nipples. The pleasure just keeps mounting when his shaft and shaft-snout grow to full intense erections and mutate further from there into much more muzzle-like, throbbing shapes. Laylee, the lust-maddened one, fervently thrusts every cock and nose-boner into Fieron that she can, stuffing into pussies on his 'elbows' between the 'thighs' of his torso-arms, cramming into a cunt in his sheath, shoving down his cock-tongue stretched muzzle, and reaching out with her own Laylee-arm to grab his widened ass and shove facecock and hermcock into both his tunnels.
With the other half of her body at this point half again bigger than the rest of her, the calm-side Laylee has lidded, distant eyes, cooly pumping cum from her cocktongue while Balros drinks. The squirrel has shifted slightly so that her leg is lifted over his lap and her balls rest atop his thigh; his cock buried several feet into her battysex. Her breasts have grown bigger and lushly pour with silken bat milk. Their shared pregnancy seems to be rapidly advancing as the squirrel's cum is added to her frothing corrupted womb. At the same time, Fieron feels a hot throbbing from within -all- of his wombs...
