Her word around here was law, and the interruptions ceased as soon as they began. Trying to relax and let her wrath subside, she refocused on the task at hand: her orgasm. Looking back down at Tania, she gave her an amused smirk, the Elf having not noticed a single thing, brain-broken by her cocks and cum. Resuming her rampage, Nix regripped Tania's hips, putting her all into fucking the Elven slut, reaming her, thumping herself against the fat ass in front of her. Cum continued to spill from their connected sexes, the floor utterly covered by the ball brew, the level of it rising steadily as more and more slimy seed fell onto it, her balls sloshing through the sea they created.

Cocks throbbing violently, they jackhammered relentlessly into and against Tania's body. Her outer-member was fully engulfed by the Elf's massive four tits, no longer visible around her face, her cock-pillows extending past her own visage. They hugged both of her monstrous appendages - the bulge in Tania's stomach equally as smothered by the ginormous mounds of soft flesh - cushioning every inch of Nix's pulsing plows they touched, which was the majority of them. The cock inside of Tania continued to pack her womb full of itself and further gouts of semen, her midsection inflated, widening her form until Tania in her entirety threatened to fall off the desk. She was turning into nothing more than hills and valleys of squishy flesh, exactly how her Mistress liked her!

Nix was going to attempt to cum again.

"G-Gonna cum," she repeated in a breathy gasp, her nostrils flaring, "get, get ready for my load Tania!"

Tania moaned and weakly jiggled herself against her Mistress.

"P-Please...!"

That was all she managed to get out, her tongue lolling out of her mouth, her blue eyes constantly rolled into the back of her skull as her cunt squirted endlessly. She had lost all the strength in her limbs, her arms draped across her massive, dual-bust, her legs hanging off the desk, jostling only from the force of Nix's powerful pistons; her whole body continued to squirm and writhe under the same outside pressure, her boundless flesh and squishy parts jiggling across the desk. Tania's cunt was no longer able to tighten around her Mistress's member either, as slack as it could be - which didn't matter much considering the circumference of the cock clogging it - unleashing her cunt honey with each thrust, her painfully erect clit constantly grinding into the Succubus's shaft.

Another deafening roar escaped Nix's lips as she started to cum, her back-and-forth movements halting as she buried herself to the hilt inside of Tania as deeply as she could, their bodies pressed together, molded against one another. Every part of her tightened as she came, flexing and bulging like the entirety of her existence went into this one climax. Her cocks lurched violently inside and under Tania, straining themselves, the knotted veins fervently pulsing; her balls finally reached the floor, four immense globes wider than her own torso weighing her down, the suffocating scrotum stretched between and against her legs like the membrane of a Cloud Dragon's wings.

There was a loud, wet splash of liquid on liquid as her cocks delivered their payloads.

In the same moment that Tania's stomach suddenly ballooned, cum gushed from every corner and opening in her tits and torso, pressurized blasts of white seed spraying into the air like numerous geysers erupting at once. The torrent of semen coated everything around around them, falling back onto Tania's body and positively saturating the Succubus's voluptuous figure, consuming her from her black-and-red hair to her already-ankle-drowned feet at once, splashing off of her, sending strands and dregs further around the room; several jets of potency even flew out of the window behind the pair, running down the stonework of the building and staining the grass below it. Ceiling, walls, doors - it was all recoated in Nix's powerful essence simultaneously, the sounds of the creamy fluid smacking against the various surfaces like the beat of a drummer in the midst of battle.

Letting out a muffled moan, Nix spat cum out of her mouth even as it was instantly refilled, her countenance coffined by her cascading concoction. Peeking through one eye she watched as her personal assistant's abdomen grew and grew, spreading out across the desk as far as her tits did, this load even more grand and voluminous than her first, and only from one of her cocks! Tania's giant tits were pushed upward by the bubbling expanse of her stomach, folding back in on themselves, excess titty-flesh collapsing onto her back and head, cum still ventilating from around them, her nipples nearly meeting across her figure. There was no stopping her bloating, gallon after gallon of awesome seed cramming into her, rearranging her organs and altering her body in ways it was never meant to be altered.

Crack!

Perking up, Nix searched frantically for the source of the noise, her first instinct leading her towards believing that Tania had somehow been actually damaged by her load or her cocks, something that hadn't happened before - though it was quickly clear that wasn't the case. The Elf was still cumming and moaning but now her body was beginning to sink towards the floor, bending against itself like something was sucking her up. The desk, shit! The weight of all of Nix's semen and Tania's expanding mass was breaking the desk in half, the tough obsidian demolished under the combined heft. Thinking quickly, wanting to avoid replacing the expensive piece of furniture or hurting Tania, she muttered a spell as quickly as she could; a shimmering portal appeared on the ground, one that looked similar to the one she entered this realm in. The desk disappeared along with a flood of the Succubus's progeny that flowed into the mystical opening, Nix cutting off her words at the last minute before it consumed her assistant as well.

Nix wasn't sure where it would all end up, but that was a problem for another time!

The moment the desk and gallons of Nix's cum were removed from the office, Tania went hurtling towards the floor; she hit the ground with a resounding thud, the semen that replaced the amount racing through space and time providing a small cushion for her body. Her body provided the real cushioning however, her massive pairs of tits and inflated-gut landing long before she did, flattening for a moment before bouncing back up like they were made of rubber. All of the virility flowing inside of her kept her ass sticking up in the air, Nix barely having to move at all to re-bury herself as deeply as she was before, her stance only becoming slightly more hunched in the process.

Unperturbed at the destruction and potential loss of her desk, Nix carried on like nothing had happened. She continued to rut into the Elf shallowly, jerking her hips back and forth, drawing more cum from her over-bloated seed brewers and engorged members, her potent gunk splashing back onto like a pearlescent storm. Tired of spitting out her own milky essence, Nix began to swallow it instead, finding that option much more appealing, the taste of her own sexual refuse sweet on her tongue and warming her stomach. Through the one eye she managed to keep free of cum she watched Tania's constant, steady expansion, nothing blocking the gigantic four tits path as they now consumed all the space in the entire room.

Seemingly at random, Nix's orgasm intensified like she was cumming for the first time in weeks. The blasts launching themselves through Tania's womb and against its back wall were pushing her flesh outward in swirling, gurgling pillars, extensive expanses of skin that looked like Greg's tentacles were trying to escape her body. More and more salty-sweet sperm drenched Nix, the Succubus too lost in the growth of her climax to consider where it was coming from even with her magical amounts of self-control and awareness. She felt a new tightness in her chest, ass, and genitalia, one immediately different from the kind that heralded her lurid peek.

There was a sudden surge of magic in Nix's body.

A rumble vibrated in her naturally-humongous breasts first, causing the Demoness to look down at her own chest, distracted from the absurd display of sexuality she was putting on and creating. She suffered through a moment of confusion as she watched her preposterous breasts begin to swell, unsure of what was going on. Then the realization dawned on her of what was happening and more importantly, what she'd done: she'd drank her own cum while it was imbued with her powers! Breaking out of her sexual reverie for just a second, long enough to shake her head at herself, Nix sighed and made the executive decision not to fight it or reverse the changes that were about to occur to her, though she had the abilities to do so. It's not like she didn't have the means to fix it all later!

Closing her eyes, she followed the enchantment through her body, able to view the glowing essence as it traveled in a space others couldn't see, not surprised at all where it had directed itself to first. She was almost disappointed at its predictability, but that didn't stop her from enjoying the sensation of growth taking hold over her; it was another reason her products were so popular, the transformation people went through as pleasurable as it was erotic - and Nix was no different. Her moans increased in intensity as the normally-grandiose weight on her chest got heavier, taking up more and more space across her torso, squishing into Tania's just as enormous ass and the middle of her spine.

At the same time her tits grew, her ass did as well. The chair-breaking cheeks stretched out behind her, changing from a shelf where people could place their food on, to an entire table that a family of four could eat at! Her hips widened in sync with her posterior, now unable to fit through the doors that were custom-made for her natural wideness, giving her the appearance that she could birth a litter of spawn without issue. Nipples unspared as well, they grew until they eclipsed the size of average dicks, huge and long enough now that they would need to be deepthroated if someone wanted to suck on them; while she was nowhere near the size of her assistant, Nix still reached the point of enhanced sexual absurdity.

Shuddering as the exploded harder and more forcefully into the Elf below her, her hands pawing at her magically, overdeveloped body frantically, Nix quickly found that her magical expansion was affecting all of her. The tightness of Tania's hole started to feel painful around her upper-member, like it was squeezing the life out of it and could crush it at any second. Fighting against the ecstasy of expansion and the grip of her assistant's pussy, Nix pulled out of her, staggering backwards, feet slipping and sliding through the cum all over the floor; yanking her cocks free of their separate prisons she grasped at them both, groaning as they pounded with power with between her fingers, pumping potent progeny into the air at an alarming rate.

She felt incomplete now that her dual-appendages were unburdened by flesh or hole, and, looking for a different place to put them, smacked them down between Tania's colossal cheeks; her ass had grown so much it was able to consume both members with ease, the Succubus's twin-rods disappearing into the canyon of ass-cleavage. Putting her hands back on Tania's ass, she slapped them together like she would a pair of tits, instantly thrusting at them, running her engorged glans and palpitating shafts across the Elf's back and against her head, Tania's body-sized tits cushioning them. Nix hammered herself against her personal assistant, cum still rocketing from her mouth-sized piss slits and drenching the room in its entirety.

"Fuck, fuck, fuck!" Nix managed to yell, spitting up her own seed as she did, her being burning, "Feels so fucking good! So intense! Fuck!"

It felt like her whole body was being sucked into her crotch, all of her nerve-endings fixated on her genitalia. They were growing like the rest of her was! Nix's ginormous set of testicles were first, swelling beyond their regular means, infused with magic. Her scrotum went first, making room for the undulating spheres within it, the fleshy, weighty sack wrapping around her legs and sinking over her feet, her muscular, long legs completely obscured by its encompassing form, veins and arteries popping out across it, each on longer than her forearms. Slowly but surely her balls followed suit, spreading across the floor and raising towards her groin without lifting, becoming as big as her tits were now - her tits that extended from her chin to the base of her upper-cock while also resting against her biceps and obscuring her muscled waist.

This lurid enchantment seemed to affect her cum production as well, her extremely-bloated balls releasing an amount that befitted their deformed size; the incredibly-altered, overweight orbs gurgled so loudly, so violently that it was vibrating Nix's entire body, nearly throwing her off balance from their ferocity. Her semen launched across the room in two unbroken streams, arcing over Tania's head to hit the wall across them nonstop, leaving over a foot of the dense goop layered against the wall that continue to build and grow even as more of it slopped onto the floor and splattered onto the ceiling. These high-pressured salvos turned into spraying fans, her cocks unable to release them fast enough, her urethras split to almost tearing.

Her cocks finally grew.

As they did, Nix's cocks expanded in time with each other, mirroring themselves perfectly. They snaked across Tania's back, slithering and sliding up her spine to her head until the swelling glans pushed past her skull. They fattened as well, synchronized in their girth growth, spreading Tania's ass cheeks farther and farther apart, her cum tunnels turning into veritable chasms for her ball cream to travel through, each one wide enough to fit two arms inside of. Nix continued to curse and howl, struggling to stay standing as her members inflated, size surging through them, her fingers bruising Tania's rear, her nails digging into her semen-soaked, soft skin.

Even when the rest of her figure stopped growing, her cocks didn't, like her magic was working extra hard to make them as massive as possible. Her purple, gushing crowns were well past Tania's countenance now, over a foot away from the rest of her body, with no end in sight. Shooting out farther than even the Elf's expanded-four-tits did, they grew and grew and grew, the skin across them pulled taut as veins filled every space they could across her shafts, visibly throbbing, sticking out several inches from the tough flesh. Their combined circumferences fought for room on Nix's crowded crotch, pressing into the sides of her thighs and the bottom of her stomach, her endowment nearly too much for her own body to handle.

"I can't, I can't..."

Nix panted wearily, pulling her cocks free once more to get a better view of their enlargement. Pointing up towards the ceiling, they reached towards it like they hoped to break through it, both of her shafts grinding across the Succubus's expanded, colossal chest. Watching through bleary eyes, cum drizzling down onto her body, Nix groaned with each new inch added to their length and girth, her hands still squeezing Tania's fatty pillows. When they did come close to touching the ceiling, they suddenly stopped, giving a last lurch as the spell faded, painting the surface above them in ball brew; if Nix had the energy to, she would've gasped at their size, scarcely believable to her own eyes.

"M-Mistress...?" Tania muttered, hardly audible over the sexual storm around her, "W-What's going on?"

Her words fell on deaf ears, Nix too consumed by her now uncontrollable lust brought on by her self-inflicted development. The cocks towering over her and jutting from her crotch were ridiculous, even more so than they were normally. Each one was as tall as Tania was and almost just as wide, Nix possessing poles that were person-sized; her own hands wouldn't be able to wrap around one of them, and pleasuring more than half of her shaft at once was an impossibility. They were incredible! Nix turned her eyes - cloudy and black - to her assistant, her breathing heavy, seeing the Elf as nothing but a set of holes to use - to use and abuse and ruin permanently, every other thought vacated from her brain.

"Nix?"

Nix pounced on the Elf once more.

"Gonna fuck you hard Tania!" She grunted, lining up her head-sized glans with Tania's cunt and asshole, "Need to fuck you hard!"

Though Tania couldn't see her and wasn't aware of what had occurred during her climactic-coma, she could feel the craving dripping from her Mistress's tongue.

"Do it! I'm yours Nix, you know that. Just don't stop fucking me!"

Growling, Nix rammed her cocks home. With their nearly doubled width and length, they mashed against Tania's gaping holes, respreading them, digging into the openings that were now even smaller in comparison than before. Tania moaned, life flowing back into her, her legs stretching across the floor, partially blocked by her tits that flowed out around her like a series of pillows fit for royalty; she braced herself on them as well with her hands, her palms molding into their enormity like clay. She cried out, her sperm-laced locks clinging to her countenance, seed flowing down her features, trying to relax even while it felt like someone was trying to shove tree trunks into her.

"Open up slut!"

Pulling back, Nix plowed forward once more, her whole body jiggling, tits bouncing in a circle, her ass cheeks clapping against her back, thighs and themselves. This attempt was more successful than the first, her constantly-leaking tips aiding the penetration, Tania's holes saturated with the steaming seed billowing from them. Both entrances yawned open to an unnatural degree, putting the Elf's natural-born resistance to the test, perfectly rounded circles formed in their place; she screamed as Nix's gnarly glans gouged her out, knocking into her walls, pushing them together until they were nearly unified into a single hole. Nix screamed herself as she lodged the enormous mushroom-shaped ends of her cocks into her assistant.

"You, you feel so big Nix!"

Nix didn't just feel big, she was big! Each cock was at least one and half times as large as it had been previously, and almost half of that in added length - but Tania wasn't quite aware of this yet. To the Elf, her Mistress always felt preposterously endowed, and she simply assumed that the sensation of being gaped more and ever before was a consequence of the magic that constantly altered her being. She would quickly learn different, Nix's member surging into her, pushing her insides to capacity, creating bulges across her torso; her entire torso was deformed now, each cock distending her stomach and chest to new heights, pushing cum out of the way to fit themselves within her.
