"God damn, I could get used to that!" Emily groaned happily, straightening herself as her climax reached its finale, "That was fucking intense!"

"It, like, really looked like it!" Jolene was hopping on the balls of her feet excitedly, anticipating her own turn, "I sooo want to go next though!"

"Well wait, what about Des-"

Clarissa cut herself off as she noticed the state the older futanari was in. Concern crossed her features as she stared at Destiny, eyes widening, pulling herself away from Chastity's hands in order to come to her student's aid if need be. Utterly silent and body slack, Destiny appeared as though she might tip over with the slightest provocation, swaying where she stood, her head down and shoulders slumped. Only the whites of her eyes showed from around several stray strands of curly hair, mouth drooping, saliva running down her chin. Having let go of her cock, her arms bounced aimlessly against her thighs, hands unclasped, fingers hanging; all that was stiff about her was her cock, which was still aimed downward and stuffed into the Succubus's face.

"Oh my God, Destiny, is everything okay!?"

"Is she, like..." fear returned to Jolene's expression, "what's wrong with her!?"

"I don't know, but I-"

Destiny groaned monotonously like a zombie.

A violent shiver ran through her body, shaking her naked figure. Stumbling backwards rapidly, Destiny moved as though she was on autopilot, feet shuffling around her own sagging scrotum until she hit the mirrored-wall behind her. Shaking against the cum-strewn reflective surface, it appeared as though the futanari was seizing, her limbs jiggling like a marionette. Her groan increased volume until it nearly became a scream, her face still expressionless; to the rest of the group she looked like a woman possessed, like she was no longer in control of her faculties. Clarissa took a step forward, making a movement to help her friend, only stopping when Destiny started to change.

It was like an invisible explosion emanated from her figure. Faster than any of the others she went through her magically-induced transformation, every part of her figure reforming itself at once; it seemed as though the energy that had flowed her from Chastity had somehow welled-up the entire time she was lodged in her throat, stuck and unable to release itself into her. Her limbs grew all at once until she was once more the tallest amongst the futa - tallest in the world is what it really looked like - shooting up nearly a foot in height, her arms and legs extending to match her new existence, now making her tower over everyone else in the small studio space.

And that was just the start.

Her moderately large, milk-engorged breasts ballooned, streams of the fluid flying from her enlarged, egg-sized, brown nipples, the dark mounds now massive and gravid, hanging over her rotund stomach and nearly catching up to Jolene's bust. For a moment it looked like she was standing up straight again, but the rest of the futanari realized that it was just her ass getting more gigantic; Destiny had already been the owner of a pair of absolutely pants tearing cheeks, but at their current rate of inflation, she would struggle to fit through any normal-width door! Clarissa, Jolene, and Emily could all see through the mirror her bulbous backside grow and grow, her hips following suit until she was about as peach shaped as a woman could get, each of the rippling masses of fat twice as humongous as they'd been only seconds before. Forget pants, Destiny would be hard pressed to find underwear that would fit anymore!

Then it hit her corpulent cum containers. Already hanging low and forcing her legs to spread, her enormous sack collapsed, thudding onto the ground hard enough and with so much extra weight that the entire room shook, the rest of the futa nearly knocked off balance from the sudden earthquake. All the wrinkles coating its fleshy expanse disappeared as the skin grew taut, incredible, protruding veins taking their places, a veritable maze of blood-pumping arteries popping into existence. It completely hid her calves and thighs - both of which had bulked up as well - everything below her groin blocked by sagging sack skin. Her scrotum stretched like it was being filled with water - but it was something much denser packing it full.

Destiny's testicles overtook everyone else's in the room combined, so fat she could use them as a pair of stools if she ever got tired! Forget exercise balls, they went beyond that size, taking up more space between her legs that existed and covering her feet, the tops raising above her lengthened knees, the backs up of them flattening against the mirror and creating more cracks across it. One alone had to weigh hundreds of pounds! They no longer gurgled with freshly-churned sperm, roaring instead, people in the next room over probably able to hear her enhanced, super-charged progeny production. If Destiny's legs were any closer together she would have been tripped by her own semen factories!

But that wasn't even the most horrifying part of her magnification.

Her cock, which had been sticking straight out from her groin now that it was no longer planted in Chastity's throat, developed to a degree previously unheard of. It actually managed to slam against the floor first, its thickening occuring before its lengthening, immediately struggling to stand up under its gained bulk. Cresting her sperm-stuffed sack, the giant glans bashed up and down as it inflated - along with the rest of her already-fattened shaft - reaching a girth that wouldn't be conceivable for anyone to be able to take - except maybe the woman who had intruded in on the class! Vibrating violently, more and more pounds of pure meat added onto its already preposterous-form, veins marbling it so completely that there was scarcely an inch of non-ridged flesh left. Hell, her urethra was so insanely wide by this point, Emily's arms wouldn't have touched the sides of it if she double-fisted her friend's fuck stick!

While in the middle of bulking up like it was preparing itself for a bodybuilding competition, Destiny's colossal organ began snaking farther along the floor, still not quite strong enough to rise on its own. Previously tied for second as the most hung futanari in the room, she steadily approached first, each lurch of her cock coming out in gargantuan expanses rather than slow inches; it didn't take her long to measure up to Jolene's nearly body-tall length, and she still wasn't stopping! It grew and grew and grew, extending out from her body like another person was forming from her hairy crotch, retracing the path she'd taken to get to where she was now like it was hunting for Chastity once more.

By the time it did finish its conversion into something incredulously terrifying, it was longer than Jolene was tall, just a few inches shy of matching Destiny's height pre-transformation. Only then did it rise on its own, lifting into the air like a battleship aiming its artillery, throbbing violently as it awoke; it stopped when it was mostly perpendicular with Destiny's body, only sagging a bit due its sheer immensity. Now that it had hit its apex - the biggest it would hopefully ever get - it was something out of the most perverse, unholy fantasies, longer than Clarissa and Emily's members stacked atop each other, and easily girthier, somehow shaming all of the onlooking trio, making them nothing more than dwarfs in the shadow of a true giant.

The other futa gawked at it in dread and arousal.

"A-Are you guys seeing what I'm seeing?" Emily asked dumbly, her breathing heavy.

"I... I think so?" Jolene questioned, taking a step back, "But I'm like, not sure if I'm dreaming or something."

"Guys we um..." Clarissa's eyes bulged in their sockets as it dawned on her what was going to come next, "We need to move!"

Jolene and Emily looked at her questioningly.

"Come on!" She grabbed their hands and jerked them to the side of the room, "She's gonna fucking cum!"

As soon as the two understood, they followed her hastily.

"We've got out of the way or we might actually get hurt!"

After seeing the force of all of their orgasms - especially Jolene's - there was no question the three futanari needed to remove themselves from the blast zone as quickly as possible. With the size of Jolene's pumped up genitalia, her climax would undoubtedly be dangerous, and would easily stretch out the entire length of the room. The threesome pinned themselves to the wall by the front door, putting them both closer and far away from the radius of Destiny's coming explosion, huddled up together as if to help protect themselves from the liquid onslaught that was only seconds away from detonating. Clarissa realized that she'd left Chastity behind, but it was far too late to go back for her now...

...because Destiny was cumming!

She grunted and her hips thrust out, sending her cock bucking fiercely, her balls far too heavy to move from their place and follow her member's lead. Destiny's brutal, purple cockhead pulsed wider, her piss slit more like a piss crater, the opening gaping wide enough to swallow an entire human head, the expansive tunnel running the length of her shaft widening obscenely. The roar from her cum factories loudened to an extreme, deafening decibel level, the veins across it bulging out like her scrotum - which was spacious enough to smuggle a body inside of - was coated in cocks, the skin across her sack continuing to stretch and creak. Eyes still white and body slack, her chest heaved, her tits and pregnant belly stomach shaking as her first salvo raced up her massive Howitzer.

When Destiny came, it wasn't in a single stream; no, her cock had grown far past that point, her potency in a league of its own. One Herculean blast fired from her cum cannon initially, but several others followed it simultaneously, using up all the extra room in her urethra, multiple hoses rocketing from her member at once. The main expulsion was the largest by far, but the others were undeniably voluminous, shooting out in every direction in front of her, the main flood exploding straight forward. Like Clarissa had predicted Destiny's beam of pearlescent paste arced across the entire studio space and smashed into the mirrored wall opposite of her, immediately shattering it and revealing the surface behind it, shards of glass lost in the torrent of futa cream.

Just the beginning of Destiny's orgasm overtook - like every other part of her transformation - the others in maddening excessiveness, the entire quantity Jolene's explosion contained in her grand opening. Despite impacting just a single, albeit huge spot on the far wall, the dark-skinned futanari's cum managed to engulf the entire surface corner to corner and then some; incredibly thick as well, it didn't even pretend to fall back to the floor, sticking onto the surface it landed on like it was completely solid. The extra streams didn't make it quite as far, splashing down in random sections of the matted-floor, creating deep pools instantly, dotting the studio in her virility. One of these added additions to her climax struck Chastity, dousing her head to toe for the umpteenth time that night, her also expanded figure buried in the reality-shattering fuck fluid.

Not that she was awake to feel any of it.

Sometime during Destiny's transformation Chastity had been driven to unconsciousness. It wasn't from all of the orgasms she'd experienced from Emily's fucking. It wasn't from her second bodily growth of the night, her figure more obscene than it had any right to be. It wasn't from seeing Destiny's ridiculous remolding either, her eyes pasted shut before she could bear witness to it for herself. What had knocked her out was the aura that had emanated from the currently-cumming futa, one that had been so overwhelming in its potency that she couldn't mentally or physically handle it, her brain shutting down as if to save herself from what it might do to her or how it might affect her if she was present to witness it!

In a way she had sensed her abilities working on Destiny, and that was enough. The power radiating off the futa came in the form of unfiltered musk, a visible-only-to-her cloud that washed over her, encompassing her body in its pungent essence. That was all Chastity needed to know, to be given some hint about how just extreme the changes were that Destiny had gone through, and she couldn't grasp it, plain and simple. So as this overbearing scent weighed down on her she went into survival-mode, something she didn't even know she could do, an ancient trait of her race that hadn't been used in eons. Brain going blank, she slipped into a deep slumber until her very being could adjust to what was happening to her.

So consuming was Chastity's comatose current state, she didn't stir even when her body was moved by Destiny's cumshot. The pressure from the futa's climax sent her cock into a frenzy, kicking up and down violently, and therefore made her off-white geyser do the same; her unbroken still first stream undulated between the ceiling and floor, and what was in between them: Chastity. Its force was so monstrous that it propelled the Succubus forward, her body spinning across the room like an absurd, sexy top. Semen splattered into the air around her as she rapidly revolved, her torso-shadowing tits and weakened limbs flopping crazily until she slammed into the wall below the initial point that Destiny had destroyed it.

Several gasps erupted from the corner of the room.

Jolene, Clarissa, and Emily were all positively frightened of what they were witnessing. To the onlooking trio Destiny seemed like another animal utterly separate from themselves - or perhaps even the next step in humanity's evolution. Though she resembled a human being, albeit an incredibly statuesque and rubenesque one, what was hanging below her pregnant stomach didn't. Destiny had a cock that looked like it could eat any of them if it so chose, and still have room for seconds, while her balls were gravidly rotund enough to be used as beds! There was no way to describe her extra appendage now, even the most poetic, verbose strings of words and phrases failing to do it justice. It was, in the most simple of terms beastly, in every way, shape and usage of the descriptor, and none of them could stop staring at it.

How could they? It was as magnificent as it was grotesque, a member truly worthy of worship, demanding that anyone and everyone kneel before it in lurid veneration. Destiny had the most virile, prodigious cock that had ever existed - and probably would ever exist - a single drop of her semen enough to impregnate the entire world hundreds of times over. And she didn't just have a single drop. The amount that their companion was bombarding the room with was enough to wipe away any traces of their own loads and pre, literally flooding it, the gooey, pearly slime rising higher and higher even as it attempted to escape through the cracks in the one door of the studio; all of the futa were up past their ankles in it, and Chastity was closing in on being completely submerged!

Though over a minute had passed since her ultimate eruption had initiated, Destiny's first blasts were still going strong; Clarissa wondered if in an orgasm so powerful there would even be pauses between her salvos. Semen continued to rain down over the studio space, somehow touching nearly every inch of wall, ceiling and floor, scarcely a section unstained by the futanari's volcanic eruption; there was even cum behind Destiny, her own body and the mirror impacted by her gooey detonation. The other futanari winced as the boiling hot fluid splashed down onto them, the temperature of Destiny's hot enough to feel like it was scorching their flesh.

And it still didn't stop.

Though she had lost control of her faculties, Destiny's body jerked harshly as she unloaded. The only reason she hadn't toppled over from the force of her slimy bombardment was because of her incredibly swollen testicles, the obese orbs keeping her propped up. Her cock was doing all the moving for her, slamming up and down and back and forth, practically helicoptering itself, her cumshots coming out in massively twirling ribbons. Each thud of her climax hitting a person or surface sent a small quake through the room, threatening the integrity of the entire building. She was creating an actual ocean of cum with her output, the exit to the studio groaning as tidal waves worth of pearlescent goop bashed against it.

The smell of her virility was enough to flare nostrils and water-eyes, Clarissa, Emily, and Jolene struggling more and more to continue watching their companion; it was like someone was holding a pair of unwashed panties to their noses that'd been used as a cumrag for months on end - and one of their cumrags at that. They had no idea how Chastity was still breathing through it all as she was the one who was taking the brunt of Destiny's onslaught. There was no way to tell how far into her orgasm Destiny was either, her streams erupting unabated, her cock seemingly permanently swollen with seed, grotesquely bloated and distorted from the amount of fuck fluid flying through it.

Time was completely absent from the room as Destiny put on the most raw, brutal display of potency ever seen. Destiny's climax could have lasted an hour or just a few minutes - there was no way to tell. Dose after dose of semen spilled from her fleshy crown, her cum factories insanely engorged and seemingly growing even as they attempted to empty themselves. At one point Clarissa tried opening the door to help drain the room - the gym thankfully mostly empty at this time of night - but found herself struggling against the tide of semen pushing against it, Emily having to use her new-found musculature to aid her; even when they did get it ajar, the result wasn't what they expected. The cum poured into the hallway, but not quickly enough, too thick to do much else but slog into the free area. But it was better than nothing!

Sometime during this perpetual progeny pissing, Destiny's climax began to wane, showing that she was still human. Her multiple streams died down to a single-but-still-massive spew, gushing onto the floor like an opened valve of a dam; even this smaller quantity of baby batter was preposterously enormous, continuing to overshadow the others. It lessened and lessened, pouring out closer to Destiny's gigantic glans, no longer reaching the same distance it had before. The other futanari relaxed once they realized their safety was assured, the shock of their friend's enhanced abilities wearing off, even if their minds were reeling from seeing it. Finally, it looked like Destiny had calmed down.
