Balros
Balros diligently sucks his knocked-up girlfriend's dick, trying to keep her calm. His face is smooshed into the soft curve of pregbelly girlgut; faces hidden by big fullfirm tits.

The diminutive, but obscenely pregnant bat clutched at her belly, palms splayed wide over the immense dome so that she might feel the countless daughters squirming within. To say that her tits were merely 'full' was an understatement. Milk streamed endlessly from each hefty nipple, backed by even fatter, full areola. "Hmmff... So many."

Balros
The squirrel's throat clenched and quaffed deeply around spouting gouts of batsperm, the hormones of pregnancy dictating a dangerous productivity. To his worry, as his heavy handpaws kneaded and stroked her fuzzy ballsac, they seemed to grow with each larger pulse of cum. The chubby brood of hermbats within your womb swelled and spilled, too; in his kneeling position, his huge shaft was sunk deep up your sex and worsening your changes when he came, too. Soon your tum rested atop his head.

Every twitch of her girthy prick, no matter how subtle, was met with a deluge of increasingly potent, unimaginably thick cum that struggled to be forced out of her clenching, twitching nutsack, distending the underbelly of her cock into a prominent balloon with every lurch of ultra-virile bat-jizz that was launched down the squirrel's gullet. 
Despite her size, her sex was a large, pillowy thing that all but smothered Balros' lap, well suited for handling not just a hefty squirreldick, but the daughters that were even now beginning to swell with their own broods, compounding her pregnancy until Balros was utterly smothered under the curve of that immense belly and the massive brood-chamber within. Save for his paws, of course.

Balros
As the fat underside of your cock bulged, so too did his throat, your shaft sunk so deep into his muzzle that his snout is sniffing your sheath. Every load fatter and bigger, demanding a larger cock through which to unload all of it. His cute buck teeth digging into the throbbing flesh felt kinda nice, too. His own loads sloshed within your welled-out womb, absorbed into your flesh or adding mass to daughters within, cumming harder as he feels shortstack hyperherms grinding their own engorging girl-tums against his pillar. As bred as you were moments before. Their stiffthick shafts hosing down his prick and adding their cum to your wombwash as well.
Your sheath finally has grown large enough that the furry ring is pushing over his head. Your taint bulges and vas defrans bloat thicker than your arm to support the sheer flood of spunk roaring from your balls. Your ass and hips finally meet his lap when your sex swells juuuust large enough to sink him all inside you, profound belly thrust up into the air on display. Your own spraying milk raining down on you, letting you taste it for yourself.

The bat has become an icon of hyperfertility and hypervirility in the the span of just minutes. Her belly wobbles and shifts with the nonstop thrusting and grinding of her pregnant daughters while Balros himself is lost beneath her swelling form, engulfed to the shoulders in a sheath with plush, squishy walls that seem to be several inches thick even despite the girth of the shaft emerging from it.
At the opposite end, however, even that plush sex of hers can't quite compare to the fantastically bloated taint that even now throbs against the squirrel's thighs, the oversized plumbing within coupled with a prostate that would assuredly leave her appearing pregnant all by its lonesome, makes for a lurid groan and gurgle with every heave of her cock, each pulse taking several seconds to deflate that fuzzy perineum. Her daughters, too, experience similar effects, digging their fingers into hypersensitive taints, kneading thick deferens, and going so far as to grind against that slab of squirreldick occupying their only way out.
