Supernatural Supersizing Ch. 03

Her relentless assault on Tania's body and sanity was practically mechanically performed, even the slightest movements the Succubus made all done in the name of achieving climax - and she was right on the verge of it. The cocks rocketing from her groin to past Tania's head throbbed fiercely, the veins expanding, small amounts of girth and length added to its preposterousness. All four of her testicles gurgled and pulled up ever so slightly towards her, only managing to lift a few inches due to their insane weight and incredible heft. Urethra swelling, breathing becoming labored, her eyes flashing and changing to the deepest, horror-inducing blackness that existed, she was close. It was close. It was here.

With a scream that shook the walls and darkened the clouds in the sky, Nix came.

She didn't stop thrusting into Tania as her dual-loads raced up her members, using the Elf's caverned cavities like pumps to expel her seed faster. The initial voluminous eruption exploded from her piss slits as her cocks were sliding across Tania's face, two stretched patches of flesh ballooning in an instant and draping over her eyes like a warm towel at the hot springs. They grew rapidly, sloshing as a deluge of pearlescent baby batter streamed into the bundle of skin - though no pregnancy would incur from the seeding of virile progeny; Nix and Tania's races were just too different to mate naturally, representing opposite sides of the mystical alignment spectrum, only deep magics able to produce a half-breed. This was just pure, animalistic fucking without consequence!

Tania's womb and bowels were blasted simultaneously, creating separate but equally as enormous swells in her distended torso, each one side by side like her Mistress's cocks were. Her stretched-above-her-head skin down to her belly button was inflated all at once, Nix pouring literal gallons into her with each passing second, the first streams still geysering from her fleshy, throbbing volcanoes without pause. It didn't matter where the Succubus's members were inside of her during her incredible dousing, the results were the same: Tania's body grew and expanded into a jiggling ball of cum. The outpouring of potency was burning hot, scalding Tania's insides as they white-washed every inch of her depths, the lining of her womb and pit of her stomach receiving the same treatment, altered into the perfect caches for the unending ball cream.

Nix's rutted sharply and wildly into her assistant as she tried to force as much cum from her vast reservoirs into her. Her humongous heaving tits were steadily raised from the Elf's midsection, pushing her entire body upward with her own steaming, liquid force. Though the majority of her milky fluid was shooting into the platinum-haired girl - her hair having come completely undone from her bun during their coitus and splaying across the black desk surface - jets of the dense goop flung from her brutalized holes, splashing back onto Nix's thighs and chest. This just emboldened the CEO further, the basting of her own body causing her to moan and pound with even harder, uncontrolled thrusts.

"M-Mistress! I can feel it!" Tania announced like she had before, squirming in bouts of unbearable pleasure under the Succubus, "It's happening again!"

Suddenly shooting up in a standing position - though she didn't stop her swift pistoning - Nix looked down at her assistant. Her gaping, reddened-from-arousal cunt, twitched around her giant member, euphoric fluids spraying out of it and mixing with Nix's own thick ball brew. Tania's stomach was nearly as big around as the Elf was tall, the sides flowing over her ribs, the tops rolling over her huge tits, pushing them into the imprint of Nix's cocks covering her face; her enormously expanded midsection swirled and bubbled with each extensive gush of cum rocketing through her, her combined swell of her baby chamber and guts mixing into one giant sphere. Nix could see her arms flail, still pinned under contorted legs, the pleasure too much for her to handle. Lords Below she looked so hot!

And she was only going to get hotter.

Despite the fact that Nix was still unloading her cum inside of Tania at an alarming rate, the Elf's stomach slowly stopped swelling, maintaining the same size even when it should have been bloating more. True to Nix's magical abilities, the effect of her mystically-imbued swimmers began to change her assistant's existence - and not just from pleasure. Her already huge tits, each one the size of her own head, got bigger, flowing across her gurgling chest and pancaking against Nix's cocks and her own engulfed-face. At the same time she rose a bit higher on the desk, her ass meeting the same fate, her hips widening as the fat mounds below her filled out, giving her an obscene set of curves that only the Succubus's could put to shame and make look small - for now!

Then the section of cum-bloated flesh under her tits started to shimmer, a flowing wave of something unnatural - unnatural and not Nix's semen - wafting around the taut area. This was all that happened at first, the glowing aura dissipating as quickly as it appeared, a seemingly random occurrence that was without reason. Nix continued to fuck the Elven slut, sending her massive belly and tits careening back and forth, straining from being packed so utterly to the brim while the Succubus waited for what Tania had been referring to previously; it looked like she just meant her expanding bust and rear, but Nix knew better. Tania's giant breasts began to shift as they wobbled to and fro, the movement out of place with what was happening, hinting at something more, something unseen. Then they lifted, pushing up around the mix of cum and cock blocking their path, flopping as something beneath them slammed into their underside, the change in her figure making itself known.

Appearing under the bottom of her still-growing breasts were two large protrusions, initially scarcely noticeable amidst the mass of swirling skin and cock outlines, sandwiched between her vast titty meat and rumbling stomach; they popped up out of seemingly nowhere, unrecognizable as a normal part of the Elf's formerly-lithe body. Then, like the rest of her, they began to change. They spread out across the top of her stomach in the spots her tits originally occupied, getting wider and taller with each gout of sludge that piped into her depths, taking on a rounded shape, features forming across their surface. The growths became more familiar as they took up more and more space on Tania's torso, swelling, pushing at the top of her insane cum gut and spreading her breasts out of the way to make room.

Pink circles appeared across their expanse, a tiny protuberance of the same color forming in their centers. After a few more moments of growth, the identity of these odd mutations was without question: Tania had grown another pair of breasts! Right under her original set, in the same place they had hung off her skinny body previously, two others were jutting into existence, mirroring the exact shape as the first like Nix's cocks did. Her newly-formed nipples hardened and elongated as her bumpy areola spread across the pale spheres, which began fully squishing into the massive ones above them, fighting for dominance on her tiny chest. Expanding faster and faster, they quickly reached the size of the Tania's continuously-enlarging upper-mounds, matching their rate of expansion and mirroring them perfectly.

"T-Two more!?" Tania exclaimed in surprise, unable to see or reach her new udders, only able to feel their quick formation as it happened, "You've - oh Gods Above - never given me another pair before!"

Nix barely heard her, still bucking violently at the Elf.

"You'll, you'll become whatever I want slut!" Nix panted at her, eyes fixated on the quad-set of breasts, her cum factories surging with increased power, "Whenever I want! You're mine to play with and change and make into whatever I desire!"

Tania squealed, her high-pressure stream of girl cream splattering audibly across Nix's body.

"Of course Mistress! I'll do whatever you want! Always!"

"That's right little Elf, you will!"

Reaching out, Nix slapped a hand across Tania's fresh pair of tits, ogling them as they jiggled wildly before doing the same to the original set. They continued to enlarge as Nix planted more open-palmed smacks across their surface, all four of the humongous mounds wrapping around the Succubus's dual-poles, one for each pair of her oversized mounds. Tania's face was even more hidden than it was before, her body above her swishing, cum-dilated center obscured by cum-contorted skin, the outline of Nix's massive members, and the series of equally enormous cock-cushions, each of them topped by nipples as big as the Elf's thumb. Their growth didn't stop either, quickly reaching a roundness that eclipsed Nix's assistant's own skull.

Deciding a change was in order, Nix gave Tania's trembling, ripe hills a last whap before beginning to pull herself out of the curvy Elf. Gritting her fangs as she yanked her members backward, fighting the temptation to bash them back into Tania, her holes still gripping her shafts like undersized gloves, Nix took several long steps away from her assistant and the desk. Floods of semen followed her unsheathing, twin-waterfalls of pure white glue pouring from Tania's slackening entrances and adding to the pool that already encompassed the floor around them, slopping onto the dense puddles. With a cry of pleasure of her own, she jerked her cocks out, the massive poles swinging upwards the moment they were free.

"Time to get covered, Elf!"

With a hand on each cock Nix fisted her fucksticks furiously. Attempting to tame the spitting serpents that jutted from her crotch like the necks of a Hydra, Nix pushed their spraying-forms down towards her assistant; this wasn't accomplished before they were allowed to shoot their load wherever they pleased, cum jettisoning across the room and hitting the stone, glyph-enchanted door. They continued to eject enormous streams and salvos as she got them under control, stray blasts hitting the ceiling and adjacent walls, the tail-end of her lengthy strands layering over the floor. Hunching her body, her tits cushioning the top of her upper member, she aimed them right at Tania's writhing, cumming form, giving her what they both wanted.

A cum bath!

Immediately the double-dose of dousing drenched Tania. They impacted her swollen stomach first, the giant globe of cum steadily deflating as it exited the Elf's slack holes and the magical properties of the Succubus's progeny transformed her figure, diminishing the amount inside of her; but it was still massive enough to block the view of the rest of her above it, though her tits were quickly matching its enormity. Moaning, Nix fired her pressurized torrent onto her assistant, creating dents where they impacted her swollen size, specks splattering across both of their bodies. Shaking her hips as she stroked herself, Nix didn't spare any part of Tania, hitting her twisted-up limbs and even the desk around it, painting the once glittery, black surface in her own special brand of white paint. Rivers flowed over its sides, the lake of virile sludge filling the room soaking the Succubus's feet.

Tania groaned and sputtered as her outer-self was made to match her inner-self. As she was being absolutely immersed in her Mistress's potency, her body continued to expand, a unique sensation in itself. Having her breasts grow so rapidly was pleasurable enough as it was, but having a second pair do the same brought her ecstasy to another level. She could feel the quad-set of wobbling spheres bloat more and more, eclipsing her engorged stomach, the flesh across them pulling and stretching as they grew; she could see them as well, nearly suffocated by her original pair, the sides of the soft, plush mounds mashing into her cheeks. They quickly became as stained with sperm as the rest of her was, buried under the piles and piles of seed that didn't stop drenching them for even a second.

Her cunt convulsed again and again as her Mistress blasted its sagging, swollen lips, the run-off of cum sliding across them almost as amazing as being fucked. She was quickly being pasted to the desk, her limbs glued to the smooth surface by the tacky, sticky sperm encompassing her ridiculous figure, even her growing-form not large enough to take every drop of testicle fluid from the Succubus. Cum started raining across her face, smearing across her eyes and flooding into her open mouth, bathing her tongue and teeth in squirming swimmers; Tania immediately drank the mouthfuls with no hesitation, relishing the taste of Nix's potency. Over and over she was lashed with burning ropes of sexual excess, the dense, long strings whipping across her being.

Breathing heavy, Nix didn't stop unloading. With two cocks and four balls, her orgasms were even more explosive and lengthy as her oversized, dual-genitalia would suggest, going on for minutes on end without pause. Taking a brief second to stop her rapid jerking, she snapped her fingers, her throne careening towards her, pushing waves of cum around as it moved; it spun and zig-zagged across the room until it was right behind the Succubus. Letting her legs give out under her, Nix dropped onto her chair, her squishy body sinking into the cushioned seat, her immense scrotum flopping over the edge of it, each of the engorged pumpkins nearly reaching the floor. Throwing her head back, she resumed her intense caressing, flinging more of her gooey onslaught onto and over Tania, covering everything in front of her in her baby batter.

"Oooh that's better," Nix murmured, her strokes slowing ever so slightly, "so, so much better!"

Comfortable in her throne, Nix's orgasm began to slow - though that didn't mean the quantity of cum she unleashed was any less impressive. Ropes from her throbbing, purple tips shot out, each one longer than an average human was tall and voluminous enough to fill a chamber pot to overflowing; speaking of overflowing, everything about Tania was positively congested with her pearly syrup. Cum gushed from her cunt and asshole simultaneously, both orifices yawning, attempting to make use of her regenerative nature to close, but failing to do so. Tania was barely even present under the mountain of cock-sauce, the occasional gurgling moan or twitch of weakened limbs the only indication that there was someone lying amidst all the semen. It had been a good load!

Relaxing as her climax turned into a trickle - occasionally burps of cum still launching from her gaping urethras - Nix rubbed a hand across her forehead, wiping off the dregs of cum that had specked her countenance; Succubi didn't sweat due to the nature of their home realm, but if she could have she would! Her cocks didn't soften in the slightest, ready and eager to go another round or five, her titanic testicles rumbling in agreement, the blood-hued poles still pulsating, the gnarly roots stretched across them keeping them aloft with her life-giving essence. Chuckling to herself, Nix crossed one of her legs over the other and stared forward, ready to wake up her assistant.

"That was pretty good, Elf!" She complimented, getting no response from the comatose woman, "Give me a few minutes, and we can start aga-"

There was a sudden melodic buzzing from a cum-covered mirror that had been discarded when Nix had cleared her desk, its surface lightning up with a swirl of glowing green brightness that shone through the muck.

"Mar'Thull be damned! I forgot about the meeting!"
