Endless Elation(Sparkle HSR Mass Twinning)

"Knock knock~!"

Sampo rolled his eyes, wanting to get this over with immediately. He didn't know how she knew he was at her door, but then again Sparkle had been pestering him for weeks now no matter how hard he tried to block her lines of communication. Hopefully this'd be painless.

"You know Sampo Koski isn't here to pal around with you? What, did you think that was a joke? Even if I am naturally funny, I really did mean it when I didn't want to do any more jobs with you Sparkle. I'm a busy man."

Despite his easygoing attitude he was definitely tense, unsure what she could even want. He could usually get a good read on anyone but Sparkle was a true enigma, her smile beaming as she giggled happily.

"Oh but this isn't a joooob silly~! It's too much fun for work and besides, I thought you'd at least appreciate getting to be the first to try it."

She was leaning back in a springy chair, fiddling with what looked like a child's firecracker. There was a pile of all her normal weapons laid out visibly in the corner which made Sampo feel a bit better, but not convinced there wasn't a malicious undertone to all of this.

"Oh? Giving out free samples are we? Well you never cared much for budgeting that's for sure. But anything you-"

"Oh dear, if you keep talking you'll be second place! I do think that Sigonian will have you beat! Not that he'd meet with me but my little prank should be opened soon, so we should really speed this up! I have to make sure our grand performance is ready in time~! Thanks a bunch in advance though soon you'll be thanking meee~!"

All she did was pull a small tab, the child's firecracker sparking to life as crackles filled the small room, Sampo not very amused by the flickering sparks raining over him as a sweet smell filled the room. Sparkle just smiled wider, beaming as he coughed, more annoyed than worried as the colored fumes seemed to harmlessly enter his mouth.

"Phew, that should do it! Now the show can start!"

Elsewhere Aventurine was curious, an unmarked package that didn't seem to trip off any scanners or warnings addressed to him with a big red smile on the otherwise nondescript box. It certainly felt too light to carry any explosives, and a shake gave only a dull, light thump. On one hand he probably should have made someone aware just in case, sending a quick message to a friend, but his impatience was getting the better of him.

"Well... Nothing ventured, nothing gained."

He still was careful opening the box, feeling for any telltale resistance of a tripwire or any kind of device, but there was nothing, his hand pulling out just a small plushie of a most contemptible girl.

"Oh great, yet another bother from her. I don't know how many times Sparkle-"

His hand squeezed in annoyance around the Sparkle doll, activating something as a prerecorded voice box interrupted with, "Hi I'm Sparkle and so are you! Yaaaaay~!"

PFFFFSHHHHH

It popped in a flurry of glitter and sparks, Aventurine coughing as the shiny flakes singed against his skin, a sickly sweet flavor invading his mouth and nostrils like a cocktail of candy-coated painkillers. He should have been scared but the serotonin sparkles seemed to make those fears burst inside his head along with a few vessels, his groans cracking up as his Adam's Apple fizzled away into burning chunks of confetti, his voice climbing up and up as everything tingled, then buzzed, then tickled. He needed to cry for help, but it felt too good, scarlet blossoming in euphoric pops inside his eyes as he moaned, a light airy titter leaving instead.

"H-Haaa~haahaha AHHHHHHN AHAHAHAAAAAAAA~ YES!"

His knees grew weak, sweat dampening his outfit, not that it mattered, the glitter flakes burning through the cloth, adding to the giggly bliss spreading throughout his body as his cock hardened. He was laughing, laughing at the absurdity of Sparkle's voice giggling out his throat. He felt horrified, confused, but above all elated…

CRUNCH

Sampo's changes weren't nearly as fun, any angry comments stifled by the sudden force of his right shoulder punching into his torso, the muscles wrenched and torn as his frame collapsed along with his balance as he toppled to the floor screaming. It was like his body had become possessed by a multitude of spirits, Sparkle oohing at the spectacle as muscles writhed like worms, bones creaking as a series of gorgeously painful snaps and slushy gurgles wracked her henchman. For a moment the pain surged as his collarbone creaked, his broad shoulder twisting as he screeched, passing out momentarily till his other shoulder joined the fray.

"Oh dear Sampo, how very unlike you. No witty remarks? Come on now, you're like the ringmaster to my circus, always ushering people in, but as you can probably tell I'm letting EVERYONE in on the fun this time..."

He whimpered more like some kind of animal than a person, Sparkle savoring the wrenched squeeze of his features as his temples throbbed, his voice hoarse from screaming as his frame brutally shrank. The pain was unbearable, unimaginable, Sampo feeling evverything wrench and shatter till he swore his mind was about to break, everything tensed beyond belief before the pressure exploded with a shifting crunch in his shoulders, tufts of brown bursting out the front of his hair, evening out the style as he pathetically groaned.

"Wha- What have you doooone you b-hINNGH?!"

Sparkle tutted, her fingers gesturing towards him as his outfit pulsed, veins of red ripping apart leaving him naked save for a few red strings sliding against his body, the rope burn adding a terrible heat to the already nausea-inducing shifts invading his form.

"Ooh naughty naughty Sampo. And here I was thinking you'd enjoy becoming my equal. Surely you're starting to feel it right?"

The strings tightened around his legs, burning away hairs as they squeezed, all new types of pain pounding at his resistance as Sparkle pulled them taut.

All he felt was pain and nausea, his toes twitching as each digit attempted to screw itself in, Sampo screaming as they succeeded as the flesh shaved away, slimming and forcing his soles to snap as sliding burning string slid between, his heels on fire as they turned girly, the nails glowing a bright scarlet. Now his feet were rubbing together, their smooth skin sending conflicting signals, his confused groans stuttering as his ankles twisted, both feet jamming into his calves as Sparkle continued to puppet his broken form.

"I mean I could always turn into others, but then I thought 'shouldn't I be able to do the reverse?' Oh how I laughed when I realized such a juicy thought, though the private research was far from fun. And I knew you'd be a buzzkill if you had found out about it beforehand. But see, this is so much better! So much fun! Ohh~ I just know it won't be long till your brain bursts through the pain into pure elation riiiight? Those tears are surely tears of joy, yes?"

Thinking was barely an option, his speech coming out mumbled and nonsensical as his muscled legs felt like meat being bound up by a butcher. Tighter and tighter her threads squeezed as he bucked, all of that dense musculature he had trained up burning and writhing as his skin seemed to tighten, bones snapping and shrinking as his legs repeatedly kicked into themselves, curves carved into shrinking flesh as his knees snapped together with another pitiful shriek. He felt dizzy as another pulse burst inside his head, brown fringes fluttering down the sides of his cheek, the left longer as it tickled his exposed clavicle. This meant another lull which meant her words could finally sink in.

"Wh-What? No you cahaahaan't NNGH dohoohoo fuck FUCK! No stohahaaap rrgh this I-I don't want-"

Pressure was building inside his thighs, warm heat melting muscle as flecks of red sizzled around his retina.

"Oh, you don't want to be part of my great cloning act?"

She seemed genuinely taken aback, Sampo desperate as the skin of his thighs bubbled, rope burns somehow scarring his skin paler, smoother, the pain heightened as new nerves greedily sucked in stimulation as it felt like his legs were boiling from the inside.

"P-Pl-heheehease it hurts! I-I'll do-hoo-hoo anything just make the pa-haa-haain stop!"

His cock felt like it was in an overn, burning pockets of muscle sparkling like firecrackers as his thighs softened, inches burning to smoke and ash as the sizzling gristle squeezed tighter and tighter around his cock.

"Oh my, do you really hate this Sampo? Are you not feeling elated?"

"NOOOOO~!"

Gods, the ropes were digging into his jiggling thighs, the plushness maddening, his hips sore from the bucking and ill-fitting bones, the flecks now cracks in his irises as brown spread over his blue-colored hair, drool and tears mixing as the heat spread upwards. Sparkle seemed to be truly taken aback, his hopes rising for just the smallest instant, an instant Sparkle gleefully noted before her concern turned to a mocking smirk.

"Well if you hate it so much, why is your body so excited? Don't lie to me Sparkle, you're actually enjoying it aren't you? That pain? Your identity? What a laugh; it's just another one of our lies isn't it..."

"What ahahare you OHHHH~!"

His hips burst apart in a flurry of sparks and cum, Sampoe horrified to see his cock painfully erect, sandwiched between two plush, perky thighs as the burst this time sent a two foot long arch of brown out from the left side of his skull, a nice match for the white, sizzling juices bursting out as his hips forcefully curved. It was maddening, pressure surging inside out while fat boiled on the edges, his bulky bottom curving as the top and bottom shaved, his ass spanking plusher with every aggrieved smack against the concrete ground. He hated this, he didn't want to be her but gods why was it starting to feel good?!

"AHAHAHAAA~ OOH w-wait SpahaHAHAAARkle what's- OHHH~! Tehheheheesting!"

It was like countless feathers were teasing Aventurine all over, his lips plumping as they locked his face into a manic grin, his jaw working against his will as bones trembled with each giggle before crumbling into a softer, mirthful visage. Even as the countless hairs on his body plucked themselves the tiny strands brushed against his softening skin, his brain dancing in utter elation as sheafs of skull crunched and shifted as even the most painful of shifts only translated to a constant, overwhelming elation.

"Mmm~ this body feels so good, but it's so crowded in here. Geez no wonder you Sigonians are such a bother. So much bothersome empathy you cheating little scamp! Ohoho~ seems like you could use a release huh?"

His own voice was lost to him, fingers twitching as his brow softened, his cock on the verge of exploding as the growing inner Sparkle held his arms stiff in front. It let him watch as his fingers writhed and shrank, each popped joint and growing scarlet nail adding to the arousal, his left glove peeling away at the top to form Sparkle's mismatched pair as his palms smoothed over. The sight was comical so he laughed, Sparkle happy to let him take over his vocal chords when it was appreciation for her act, his new hands patting the mismatched bulk behind them.

"You know, you're lucky to be alone. I can't imagine how sexy it'd be to watch you resist to the end, but I lost this silly gamble. At least I can still mold you. Well Avvie? Finally ready to join our tahaahAHAHAHAAAaavern?"

Her mocking devolved into giggles and moans as her hands squeezed his forearms, the mass leaking out or compressing as his muscle fizzed into jiggly, teasable fat, Sparkle's dexterous fingers really dancing over the skin, savoring his euphoric moans as bis and tris melted to plush, soft playthings. Even his shoulders only needed a few tugs to round, sensually rolling them as they sloped enticingly.

"Don't worry, it's not all just a one girl show, for this next part I'll need a volunteer! Oooh~ look at such a firm, raised arm. My, what an eager participant!"

He couldn't stop his cock from throbbing, just a brush from her fingers making it leak excitedly as inside, Aventurine struggled to even find a reason to resist. Like the fingers slowly stroking and teasing his cock, countless phantom copies were laying waste to his mind inside his skull, fingering the folds of his brain, pinching the naughty bits that were struggling to hold onto responsibility, tickling his pleasure centers. He could feel them nudging and molding, every bit of his natural empathy slowly being crowded towards the center, the magnification making the room echo with faint voices of far-off passerbys, neighbors, his own horror at what was to come just a flicker amidst a sea of other wants. And all the while Sparkle's fingers picked up speed as they stroked, eager to speed things up as her other hand began massaging his full sack.

"I'm not one to say no to a bigger audience, but this is meant to be a private show. Besides, who wants all this stress and worry when we cahAHAHAAN AGGHH n-no doooohohohooo~ a bit of resistance? Ohhh~ that just makes it more fun when I do th-HIIIISSSS~ AHHHHAAHAHAHA YES YESSSSS~!"

The inner hands squashed all of that pesky empathy flat while Sparkle's thumb jabbed between his sack, her fingers stroking expertly as elation burst through every inch of his body. The rings of his left eye warped and popped with the angling of it, thick ropes of cum dragging away his Sigonian traits as the voices ceased, save for his own crazed squeals and laughs. His cock made a sound like a deflated whoopie cushion as his height spewed out in a glittery rainbow gush, Spaventurle feeling faint as constant elated bursts of pain corrupted his pink matter to a bruised crimson, resistance actually starting to hurt to even consider, the joy of Sparkle consuming more and more.

His left eye glowed in elated glory, his right only faintly resisting with a bare flutter of anxiety as Sparkle stroked and squashed his manhood tighter. He must have cummed out over a foot of height and the room was a mess, his lower half splattered with fluids of varying viscosity, each squeeze of his balls making the releases slicker as his insides began to bubble and spread.

"Mmm~ there, those pesky voices are gone and your disgusting gene pool's almost washed clean of that dirty influence ahh~! See, isn't this better? Finally your mongrel mind's opening up to the only person whose understanding matters. Mine! And speaking of ohohOOOHpening uhhhp..."

Now the fingers were actively pressing against his balls, trying to cram them inside a gap that was moistening, sakura patterns beginning to flicker over the rings of his right eye as he panted in resistant pleasure. He firmed up his stomach, the fear of losing his cock stirring up resistance as much as his insides, that fear making this so much better than just some boring, simple-

"Coochi coochie c-OOOOOHAHAHA HAHAAAAAHHHN AHHHH FUUUUUUCK~!"

It was just a brief mental lapse as Sparkle ignored his cock for a second, her half-gloved fingers hesitating just a moment over his bared core before diving into a feverish round of tickling. The laughter punched into their guts almost literally, driving his abs into his diaphragm and stomach as the first few came out choked as internal muscles unclenched. Each gleeful grunt squeezed his core like the doll that had started his conversion, sides dimpling, muscles flattening, every galeful burst sucking it all into a corruptive cuteness as it all came to a head once his balls were the next thing to punch inwards.

It was utter elation, the pleasure so grand he was at a loss for words so he just laughed and laughed and came as his mind shattered, two scarlet eyes burning with bliss as every last dreg of masculinity shot out Spavenkle's cock.

"I d-don't wAHHHNt to becUHHHM y-you SpahAHAHAaarkle shiiit!"

He was doing a crappy job at sounding convincing, his cock leaking, tongue lolling as he eagerly gave himself a thigh job, pain racing through his entire cock as some form of blue balls kept his releases constrained, his insides rumbling as more sprouts of brown erupted from the sides of his scalp as Sparkle just shook her head.

"There you go killing the mood again, but this time that isn't allowed Sparkle."

He cringed, feeling his innards throb alongside his brain at being called that, Spamoe shuddering as he could feel things trying to slither around. Sparkle could see he was starting to break and was more than happy to continue making her stubborn lackey come around, stringing him up as his hands were tied behind his back, savoring his horrified squeals of pain and pleasure as she moved towards him, ready to make him break.

"Do you understand how frustrating it is to have you constantly on the edge of the line only to back away just because of some idiotic code? Oh dear, so inconsistent, even your speaking pattern never settles down."

She pulled, forcing him onto his toes, Sparkle grabbing fistfuls of his half-formed ponytails while resting her knee against the small of his back.

"But that's what makes this so fun Sparkle! So rewarding. Don't be scared, we're crossing the line together even if I have to DRAG you KICKING! AND! SCREAMING!"

SNAP

Sparkle pulled at the pigtails, tearing at his scalp, Spamoe screaming as weak spurts of cum sputtered to the floor, his face pulled tight, his back aching in the utmost pain as the vertebrae of his spine were rammed till they shattered. The pain was so overwhelming it caused a misfire, two pigtails unspooling in wild, explosive growths as his height collapsed, his entire skin buzzing as his squeals turned to moans, the elation undeniable as he bucked like an animal in heat. He needed her to stop before this went any further, h-he needed moremoremore~!

"NO NO N-HOOOOHOHOHOHHH~ PLEEEHEEHEHEEASE SPARKLE I DON'T WANNA BEEHEHEHE YOOOOU~!"

God he sounded pathetic, the thought turning him on as another strained release spat out his tip, his cheeks and chin rounded from the intense pull of his pigtails as Sparkle just whispered in his ears, "Liar liiiiiar~! Just like me. You're having so much fun with this game, aren't you Sparkle?"

"NNGH Nohohooo I-I-"

His cheeks felt sore, at first from the squealing but now he could feel something else, that delectable pain fucking with more than just his sense of pleasure, the corners of his lips twitching upwards. He tried to lower them but it felt unnatural, his lips naturally resting in a gleeful smile, a match for the one staring down at him as she saw his grin struggle to turn even neutral.

"Uh uh uhh~! You can't hide that grin from me Sparkle. I always thought you should smile more; let's see how wide those lips can stretch~!"

She began running her fingers around her struggling captive's body, pinching and stroking as his muscle tore and softened, savoring every adorable noise as she ever so slowly teased him into her shape. She poked and prodded till his core was smooth, roughly jabbing a nail in his navel as she carved it thinner, taking great care to make each squeeze and curve be as painful as possible as Spamle begged, giggled and moaned in equal measure. His smile was growing more manic, his temples throbbing, his cock desperately throbbing as sakura patterns flared with each pulse of hungry need. Soon Sparkle's fingers were tracing his nipples, loving the way her near twin responded like a pet begging for a treat, his desperate begging sounding sarcastic the way his voice mirrored her mannerisms more than his own as she lazily watched his nipples stiffen.

"You want to know what's really funny?"

He shook his head, but she continued anyways, his areolas widening with each circle, Sparkle teasing his cock with her free hand just enough to keep him on the precipice.

"The longest part about making this work was making it so painful it'd fry synapses. I can actually control that, but since everything's just so impossibly fun to me I never really bothered with pain like this since I never knew the difference. Really, I could have turned you into me two months ago and your mind would have popped like one of our fireworks. You wouldn't just burst apart, you'd shatter instantly under a barrage of the highest elation instead of-"

Rather than using words she roughly pinched his nipples, splattering her with cum and drool as he screamed, his pecs perfectly pinched between her nails as his nipples pulsed, shredded fat squirming and tunneling under as half his irises burned with crimson lust.

"Wh-Whyyyyy~? Why is it sohohoHOHHHH P-HAHAHAHAAINFUL?!"

Fuck asking that made the answer spark, his lips curling tighter into an eager smile, his chest throbbing, bloating, strings digging into his sides. Fuck fuck nooo d-don't-

"Come on Sparkle, you know the answer. You know exactly why."

It tingled in his brain, Spamkle giggling, groaning. It was so obvious but he didn't want to understand, yet it stuck like a sneeze in the back of his throat, pressure mounting in his chest, behind his eyes, between his thighs. It huuuuurt it hurt so gooooooood~! He h-had to nngh god just get on with it al-

"B-BECAUSE IT'D BE SO FUCKING B-HOOOHOOOOOHOOORIIIIIIIING AHHHH YESSSSS!"

Sparkle pulled at the answer, rewarding her nascent twin as fat exploded behind his nipples, thick tits straining against their string bondage as they thickened and jiggled. Messy ropes burst at once as Spamkle's eyes fully reddened, the smile unstoppable, the elation rising and rising as the barest remainders of his mind struggled to resist, to keep the fun going yesss~!

"AHAAA AH AHHHHAA~!"

The former Aventurine's form shrank with the opening of his slit, cum gushing everywhere as his former outfit opened into a much more open kimono. None of those constricting business suits or stupid corporate meetings mattering as raw elation filled his form. It bubbled inside her ass as she spanked it, cumming as her legs thinned, her thighs bloating, her scarlet eyes rolling upwards as her calves drained their masculinity out to the floor as her feet feminized wonderfully.

Everything was orgasmic, the cold floor against her skin, her cum-slicken body rubbing against itself, but that absurd Sigonian statue still standing erect between her thighs was the most fun to play with as she rubbed the balless shaft. Deep in the dredges of her skull she could still feel some religious fervor for an old god, the Gaiathra... something. Too long. She still had some of her former self's memories in there, some proclivities yet she increasingly found them disgusting, moaning out the only god that'd matter to her from now on as she stroked her cock.

"Mmm~ if this is a pillar for the old goddess then let's sink it into Aha's elation! Ahh AHHH AHHAHAHAHAHAHAAAA~!"

Her hands squeezed as the thick cock thrust into her snatch, mixed fluids spurting out chaotically as they covered her chest and face, her nipples coming to life as elation made them blush.

"YES YESSSS AHAHAHAHAAAAAHN JUST POP INSIDE AHHHLREADY IT"S SHOW-GHHHNGH~?!"

Her tits had been steadily rising, her former tip popped into an erect click that was nestled right on the verge of her spread lips when a shock hit her, pain thrumming through her form as the raw pleasure made her jiggling tits feel the tear of muscle spreading, her innards half-torn from the nearly inverted traces of her former shaft. Normally this would have broken someone but Sparvle was so far gone it only turned her on more as she heard footsteps echoing, someone coming as she spiraled into further corruption.

"Aventurine, what is that dreadful moaning? Don't tell me you opened that package. I swear I don't know why I even bother with such a risk taking mor- Oh my word!"

Ah right, she vaguely remembered calling in someone, the self-important doctor so comical Sparvle almost considered leaving him as is, but that wasn't her plan, her thighs squeezing just in time to force her former cock to pop as she let out an orgasmic moan as Dr. Ratio's cheeks turned almost as Scarlet as his eyes would soon be. 

"Oh goooood~ you're that genius I was told could finally make me feel complete! Aventurine told you what I needed right? He said a handsome genius like yourself could finally cure me."

As easily as her body had shifted, so had her situation, the chaotic temptress moaning as she rubbed her nipples, hiding the last few surges of growth as she played into the doctor's self-importance.

"I'm not sure what he said but I am a purveyor of intellectual pleasures, not... whatever lead to this soiled state of-"

"Oh no, so you don't know how to please a woman? But he said you knew everything? How disappointing..."

It didn't really matter how far he went, what mattered was that Sparkle could see the doctor coming closer, clearly hitting a sore spot of his ego as he yelled out, "Of course I know something so rudimentary! I just have better things to do than please some harlot who dares to- ACK!"

Of course once he was close enough, her legs wrapped around and threw him to the ground, her former juices dripping onto his clothes and body as she made quick work of his outfit, tearing it to shreds as she began jerking him off. Even his groans sounded haughty, Sparkle amused as she rubbed his cock between her hands, then her tits, slowly running it down till it was being pleasured expertly between her soles. He gave a quivering grunt as she squeezed his tip between her toes, forcing it inside the shaft as he came.

"OHHH~ good heavens wh-what have you dUHHHN~?!"

Sparkle giggled, rolling her eyes as she began pressing on his balls with her toes, watching the spots where her glittery cum had splashed turned brown.

"Don't you know anything idiot? Glitter, Sparkles... they have a habit of getting everywhere..."

Sparkle let her former lackey stew in his juices as she enjoyed watching him struggle to resist, her sakura patterns flashing in his eyes whenever he came, his stubbornness never so entertaining as now. She could sense he'd be the second to turn, perhaps even third at this rate, but she was having oh so much fun with the test run that she hardly cared. But there was only so much whimpering as he struggled against elation that could keep her entertained, so she decided to add some hope.

"Fine you spoilsport, I'll give you a chance since you answered that question so well. Let's play a game. If you can win I'll fix you."

She even let her ropes go slack a bit to emphasize, Spamkle rolling on the floor but clearly listening, flickers of awareness still present behind his eyes.

"I'll even make it easy. Let’s play a game of hide and seek, okay? I'm going to hide something and you just have to seek it. I'll even only give myself ten seconds and not move from this spot. Sound good?"

Spamkle nodded, groaning as every thought now came with a chorus of Sparkle's voice giggling, every moment sending him closer to collapsing under the corruptive elation. He still wasn't a fool though, the last two minutes not quite as torturous as the other parts of the change as he prepared to take advantage of Sparkle's hubris to-

"Alright, time to hide it. Ten, nine, eight..."

She pressed two fingers against his left testicle, grinding it inwards as he spasmed, his screams reaching new heights as it emptied its load.

"Seven, six, five, four..."

Sparks of unimaginable elation burst like crackers as drool splattered out his mouth, his head rocking back as she wormed his ball in, rolling it like a marble as it was mashed and thrust, her fingers chasing it deeper down a hidden fox hole opening up behind his cock.

"Three, well you get it. Good luck lackey. I made it nice and easy to find. How kind of me, right?"

Spamkle's fingers scrabbled at the freshly opened hole, his fingers desperate to try and grab the leathery sack splitting as muscles clamped and sucked at his receded ball, his cries growing to hoarse pants the moment his fingers slid in as he fingered himself without thinking. His fingers were in him, pleasure nerves condensing, feminine bliss filling his form as it raced across his entire body as his fingers accidentally thrust deeper. His other ball puckered, the last of his seed erupting in a multicolored blast that fizzled out, his fingers slippery as they jerked inside his spreading slit. Each desperate pinch only shoved his testes further inside, the tip of his cock spreading wider with a clear spurt of vaginal juices as he slammed into the ground, orgasms chaining as the structure of his cock began to soften and sink.

"Oh dear, and I made it so easy for you Sparkle. Time for a penalty. Here, let me help you, this game's called pop goes the weasel."

He was on hands and knees, his right hand three knuckles deep as Sparkle pulled it out, slapping his palm against his cock as his screwed up features loosened with raw elation.

"There's the weasel, now just..."

She didn't even need to guide him, the horny mess of a lackey grinding the heel of his palm as she squashed it, her screams giggling up to a maniacal laugh, her resistance so silly, the pain of her cock stretching as it stuck to her inner walls and spread open, burning so marvelously it was like her entire brain was a firework exploding as another Sparkle came into being, eagerly crossing the line as she thrust her fingers into the spongy shaft, carving past that silly barrier as she moaned and squealed.

"YES YES AHAHAHAHA GET IHHHHHN THERE GET AHH AHHHN AHAHA OH FUCK IT'S OHOHOHHPENING IT'S GAHAHAHA FUCK MY WEASEL IT'S-"

POP

Sparkle looked to the original, utterly elated, every muscle fucked sore as she beamed. She could feel it, every part of her brimming with elation, their fervor infectious like a laugh, the slimy fluids leaking from her crotch sparkling as she squeezed her plump bottom. The thought of doing what had just been done to her to others made her sopping wet, the soreness just making her feel more excited as her brain throbbed.

"Ohhh~ I'd say this was one hell of an ohhhpening ahahahaaact~ sister."

"Opening act? This was the tech rehearsal silly! The real show's coming in a few days, our other sister's just making sure the 'practical effects' work too. Mmm~ but god that moaning, that desperate, pitiful show you put on..."

She didn't have to say much more, her clothes torn to ribbons by her clone as the twins eagerly moved onto group masturbation.

"Gah ahhhgh y-you can't do this! I'll have you know that I-HIIII HIIIIVE Uhhhndergone intense intellectual studies so my mind won't collapse under such p-HEERverted GAH d-durehehehess... Furthermore-" 

Across town the other Sparkle was rolling her eyes, her big toe rested firmly on the recessed hole of Ratio's cock while her heel pressed on his balls. He was going on and on about his intellect, how he couldn't lose to an idiot between moans as she slowly stomped his cock into mush as the pain only made him more annoying. She wanted resistance, horror, pain, not a fucking lecture from this pompous ass.

"I can't believe I've found a bigger buzzkill than Sampo. Such an ungrateful audience member. Maybe this will shut you up."

She snapped, her fox mask materializing over his face as it muffled him somewhat, spiraling strobes of light and elation blasting into the doctor's eyes as he began to convulse, but even that couldn't shut him up.

"OH GOD WHAT IS THIS AGH STAHHAHAAHHHP Oh no OHH OH! I can't close my EYHIHIIIES~! TAHAHAHAAAKE IT AHHHHF~!"

Convulsions wracked through his body, a series of slimy pops sounding as his body began to slim, cum pulsing under Sparkle’s foot as she put more of her weight onto his softening cock. He squealed for the following minute as she stomped his cock into a pussy, her heel grinding his balls inside as brown locks slithered under the mask, the hands desperately trying to tear it away slimming with every pull, the nails sharpening to scarlet points as Sparkle flicked the last of his masculinity in with her toes as she crawled on top of his shrinking body.

"AHAHA CAHAHAN'T HOHOHOOOLD IT IHIHIIIHN OH GAHAHAHAAAWD MY INTELEEEEHEEEHEEECT I-I'M GNNNGH~!"

Clear jets sprayed from the new girl's pussy as Sparkle molded the convulsing muscles to curves, smirking as his fingers stopped trying to pull the mask and instead pulled on his growing pigtails as his chest thrust up with a sickening pop of his spine.

"I'M GEHEHEHETTING DUHHUHUHUHUUUMBER NO I- I- OOOooooh~..."

Sparkle made sure to start squeezing his pecs as the nipples firmed, breasts bubbling under her grip. The former doctor had lost his D, his Height, and now it seemed his Pretentiousness was being flushed out her pussy as the slender curves under Sparkle began to grind against her teasing, the moans less resistant and more eager as the glowing red from the mask gained a sensual pink to the flashing colors.

"Yes yesss oh fuuuuck I can't thiiiink it's sooo goood ahaaaa nngh f-fuck I think I'm ahahaaabout to c-cuuuhm out my- AHAAAAAAHAHAHAHA~!"

Sparkle was rolled to the floor as she was covered in fluids, the former Ratio''s body giving a final shudder as she ground her knee between Sparkle's crotch, the mask slipping off to reveal a perfect copy of her face as she gave a glance so filled with disgust it nearly made Sparkle cum on the spot.

"Oh come on you bitch, that was barely any fun! You should have dragged that out and made that genius beg. Maybe he was right, you are an idiot."

She roughly groped her twin as she made her moan, her free hand snapping its fingers as strings wrapped around to turn into ribbons and a red bra and panties.

"I suppose you are me since we're all Sparkle, but I have oh so much aggression to take out and I don't really give two shits about the nuances. Ugh, that intellectual's still clogging up my brain with all this annoying crap. I'll have to fuck every last piece away."

She was squeezing so hard it hurt, her knee relentlessly grinding away, sadistic glee filling her glare as she prepared to make herself her bitch. The test run was done, and they had a lot more Sparkles to make before the grand finale of their plan as two sets of Sparkle enjoyed finally finding someone who understood them perfectly.

Sparkle yawned, watching through a pair of binoculars as her guests of honor played out their silly drama, not caring much for the overserious tone. She had been rooting for Caelus and Firefly before her plan but it was obvious that the only ship that mattered was Sparkle, Sparkle and Sparkle. Other hers had their own surprises for all of Penacony set up, but they were trying to synchronize for drama's sake as Sparkle gave live updates to the other hers.

"Kay Firefly's still talking about their roles, bla bla bla just fuck already! Well... guess they will once they're all- Oh she's grabbing it she grabbed the thing!"

Down below a very serious scene was playing out, time running out as Firefly prepared to sacrifice herself to save everyone else. She didn't seem to even want to give Caelus and March a chance to convince her off this sacrificial path, the threat of Sparkle's bomb too much, and the weight of her crimes were-

"Boring. You're taking too long so 3,2,1-"

Even inside a SAM suit, Firefly's panicked reactions were evident, Sparkle getting a good laugh as her "bomb" went off in her hands, knocking the silly Stellaron Hunter onto her ass into the water as seemingly harmless fireworks burst overhead. All across the city thousands of sparkly explosions filled the sky above with a barrage of colors, the air soon clogged with the rainbow smog and glittery debris. It didn't take long for her to hear people coughing and groaning as a quick glance showed a few of the random boring background stumbling to their knees. Surely a few of those odd quivering noises were moans in the distance, but Sparkle was fine watching the show unfold below as she teased her slit, ready for the real fun to start.

"Ahh S-Sparkff kffle! The bomb what-"

Firefly was still shaken from the explosion, not like fireworks were much of a threat to a SAM suit, but she hadn't been prepared to be blown over mid-noble sacrifice. She was fine albeit tingly all over, some fizzling cosmetic explosives sparking their way into her suit while she half-crawled her way out of the thick smoke cloud, groaning as her hands were utterly soaked amidst the awkward...

"H-Huh?"

Firefly had been dazed, but the water brought clarity, a few menus beeping with error codes she had never seen before, her armor-clad arms seemingly exposed from the elbows up? Or no, it was much weirder than that, metal melting and compressing, turning to white cuffs as rainbow-colored rust patches spread over the high tech mech suit. With the confusion it took another moment to notice something off about her fingers, a general hard to place offness to everything, but the scarlet nails stretching from her fingers were not the color or style she had even moments earlier. What was going on?

Caelus and March were wondering the same thing as they looked on, March wafting away the smoke after unsuccessfully diving in, the two confused at the seemingly melting mech suit that had withstood countless attacks, yet seemed to be baring all as the flustered pilot inside stumbled to and fro.

"I don't- eek what's g-going ahhhn with my bodys-sOOOHt~?!"

It was really riding up some unseemly places, Firefly blushing as the thinning liquimetal turned a dark blue and seemed alive the way it was, w-well violating might be too strong a word but she didn't like the way it was squeezing against her chest and ass and the buzzing w-was oh god no the helmet was starting to open she didn't want them to hear her ELATION…

Wait, why did she use that word? Firefly was conflicted, knowing something was wrong, but embarrassed by the sticky, throbbing fluid wrapped around her core, her cheeks bright red as she tried to hold back more moans. Her SAM suit was dissolving quickly, her bodysuit glued to the tearing chunks of metal as more of her arms were bared up to the shoulders, her screens glitching red and pink as the heat worsened inside her body. She shuddered, her terminal disease sometimes giving her waves of random nausea and random aches across her body, but as if a switch had been flipped it had all somehow turned to pleasure.

This was all so very wrong she was a trickster not some- The heat built, her legs kicking a storm and splashing as chunks of thigh and calf were revealed, most of the sloughed off metal condensing into a pair of heels as the error messages were dizzying. Constant twinkling, flashing, sparkling-

"GYAAAAAAAAA~!"

Without warning Spirefly came, bucking wildly in the water as she grew damp all over, kicking away the unneeded junk as her hips and thighs burst through the plating. She didn't know it but her disease had just been ejected down to the genetic level, the building pleasure building as she finally realized something horrifying; her error messages shouldn't be a burning spiral of pure, utter elation drilling into her head the longer she stared at the pretty-

"Firefly are you um... Wh-What's happening to you, is this a prank?"

Hearing Caelus's voice made her brain spasm, her own crush turning naughtier as a leg kicked, blue latex sucking tight against her pussy as it buzzed against her clit, Firefly unable to stop her body from cumming as she tore the headpiece of her SAM suit off, revealing a familiar white and red fox mask that had been reworking her entire subconscious for minutes. Sparkle was doing something and she had to, h-had to laugh at how long it took her to see she was part of the show~!

Caelus and March were horrified to see Firefly's half-shifted face once she pulled the mask off, her gray hair gaining streaks of brown with every pleasured squeal as more of her body revealed itself. The latex was unyielding, molding her core, squeezing her petite waist even tighter as her breasts looked even perkier under the tight latex, a collar forming as Firefly's left eye pulsed pink as sakura petals danced over her vision.

"S-S-Spaaahrkle d-hihihiiiid some- AHH YES YES AHAHAAAAAA~!"

Her fingers suddenly dived between her thighs, all of the moral complexities and inner turmoil gushing out in slick spurts, the elation cutting through every internal thought like a Gordian knot, everything becoming so simple as a set of bunny ears popped out from under her chestnut locks. Good and evil? Light and shadow? None of that stupid shit mattered compared to feeling bliss in every action, every word, Sparkle feeling incredible as she finally let go of every burden as she turned to the gaggle of onlookers.

"Ohhh~? Did you like the show? I bet you've never seen someone pull a rabbit out of a firefly!"

Neither of them seemed amused, more freaked out, which still made Sparkle giggle.

"This isn't funny Sparkle!"

"What did you do to Firefly?!"

She acted offended, savoring their ignorance while it lasted, an eerie wailing of moans and squeals in the distance letting her know her wet dream was coming true, and she wouldn't let these two spoilsports mess with her fun.

"Oh you're looking for that weapon? I'm so confused March..."

She acted all innocently, letting them breathe in more of the firework fumes as the sparkles continued to rain down, Sparkle shocked she could even keep a straight face at how oblivious they were.

"After all, you're holding the only weapon that matters Sparkle 7th~!"

She giggled as March suddenly screamed, Caelus and her both horrified to see her usual camera had turned into Sparkle's gun, and March's hand was a perfect match.

"Let go of it!"

"I-I can't! My hand's got a mind of- Oh no no-"

Her left hand had shrunk even smaller, her nails a bright red as it started to aim the confetti gun towards her temple, her right hand struggling to rip it away as it misfired. The confetti swarmed her right hand, merging into a glove as she lost control of both. She was in a full panic, barely able to even start a cry for help before her hands jammed it against her forehead.

POP

"NOOOOOOOOOOO~!"

Her body flung back, pigtails bursting out the back as her entire head molded to Sparkle's, her tongue lolling as an overpowering orgasm wracked her entire body.

"OHNONONO SHE'S IN MY HEEEEEEAD SHE'S I-HIHIHIIIIN MY-"

Her hands slid lower, tears streaming down bloodshot eyes, aiming the joke gun right inside her navel before yet another-

POP

"OH FUUUUUUUUUUUUCK~!"

Her frame shattered, memories spurting out in a violent display of ecstasy as her legs thrashed, her clothes bursting into a sea of red petals, leaving Sparkle's kimono wrapped around her body. Everything was amped up to 11 as her internal camera roll was erased, parts of herself popping with each click of the gun as the raw elation sent her heels flinging off shrinking feet. Markle wasn't sure if she was crying or laughing as the gun aimed between her thighs. Caelus was stumbling towards her, seemingly unaware of the burgeoning sakura petals, his clothes looking loose as he tried to help. It was a comical sight, the laughter building and building as she groaned, the last of her will struggling as she begged him to, "Hehehehhhhlp m-heheheheHEHEHEEHEE"

POP

"AHAAAAAAAAAA~!"

Her brain popped alongside her pussy, another Sparkle cumming into the world utterly elated as her twin in the suit pulled herself out of the water, pincering the Trailblazer between them, not like it really mattered. There was only one question that did to the two of them.

How long would he last…

Caelus felt drugged, his skin buzzing, bones creaking, the horror of seeing two of his friends turn into Sparkle almost making him break out in a fit of giggles... He had to shake his head, his thoughts caught in a smog of rainbow-colored glitter, his cock hard no matter how hard he tried to will it down.

"P-Please Caelus heeeelp! Ah I-I can fight it but I need you! H-Hurry!"

He stumbled towards March, hopeful for a second that maybe it wasn't too late. That just made him easy pickings once he was in range for Sparkle to raise her gun with a smirk.

"Geez, what a goody two shoes! A change of clothes for the Teacher's Pet."

BANG

Caelus crumpled to the ground, his usual outfit erupting into a chaotic flurry of glittery strips as he was shoved into a schoolgirl uniform made for a much smaller person. The skirt's hooks somehow stayed linked despite the hem threatening to snap with every move, his legs squeezed by black pantyhose that barely went up to his mid thighs and an agonizingly small dress shirt and blazer. Unlike the skirt, the white blouse didn't even try, buttons popping off, leaving him half-stuck trying to wriggle out all while the pain sparked odd shocks of arousal through him. It was hell and heaven and he couldn't even properly wrench his face the way he wanted due to the red hair ties tying his short hair so tight it flattened the wrinkles of his brow. He had only managed struggling half to his knees when the former Firefly giggled at the easy target, Caelus yelping as Sparkle lovingly pinched his raised tush.

"Oh good, looks like our eager student here's such a good girl she's even volunteering for detention! Isn't that... just..."

The more she groped his raised ass the more the flesh began to perk, Caelus awkwardly resisting between groans, his cock twitching with every squeeze till she gave him a moment of respite, only to start the punishment in earnest the second his body slackened.

"HI! LAR! IIII! OUSSS~!"

Each smack forced a grunt, then a groan, then a squeal from the Trailblazer's lips, the cum spanked out in small, unfulfilling bursts as his internals rattled around like a game of marbles. It was a struggle not to just moan pervertedly the longer it went on, every syllable of Sparkle's voice accented by a spank as his ass eagerly bloated to receive the punishment, the pantyhose rubbing against his balls th-though hadn't they been further down his le-

"Hey don't get all glassy-eyed yet! We've barely even started. Come on, you're the Trailblazer! Resist more!"

The other Sparkle was now squeezing his cheeks, her handling getting rougher as his features softened.

"B-B-Buhht I cahhn't-"

She smacked him hard, half a ponytail erupting on the opposite side as his chin half-shrunk, his entire face scrunched in mismatched, grinding pain as Sparkle mocked him.

"B-B-Bu-Bu- I didn't know you were such a nerd. Maybe this'll help you spit it oooout~!"

She pulled the trigger but purposefully aimed lower, his lower lip plumping as he coughed out his Adam's Apple as a ball of confetti, even his wheezes sounding like a party popper going off as his voice cracked into theirs. Said confetti wrapped over his eyes as a pair of faux glasses, breaking the bridge of his nose before it perked upwards.

"There, doesn't that fit a nerdy do-gooder like you? Ah wait, maybe I should have let your nose stay big so you'd even sound all congested and nasally. Still, you play the role of the easy to bully senpai perfectly. You just make me want to-"

She slapped the other half of his face, shaping the other cheek, giggling as drool splattered from the confused moans of his feminizing body as both cheeks were slapped in earnest. Pigtails fluttered longer and longer, his ass singing with pain and elation with every rough slap, his prostate bursting from the intense jostling as cum gushed out his cock as it slid into the pantyhose with a weak flop.

The constant abuse was rippling through his form like earthquakes, sheaves of bone crunching together as his shoulders sloped, the jiggle of his thick ass spreading down his thighs as his height sank lower and lower. He had to resist, had to stay strong, just barely hanging onto his sense of self as his cock unloaded chunks of masculinity to the delight of the twins.

"NNGH ST-HAAAAAAWP! I-I WOOOOON'T- GAHHH~!"

The two Sparkles gave him a round of applause on his softening body, giggling as his knees snapped together, their hands starting to get frisky with more of his trapped, pliable form.

"Good, that's the spirit!" one said as they painfully squeezed a thigh, making sure it was curving in all the right spots.

"You can do it! If you can resist us you'll be able to undo it all for sure!" encouraged the other, stepping on his left foot till it crunched to a dainty twin.

"Yes, keep proving all that incorruptible human will garbage to us!"

She was pulling on the pantyhose, squashing his balls as they tightened to his body, his calves giving into the pantyhose's grip as his cum thinned to a soapy texture.

"Incorruptible Sparkle! Oh no I think this nerd is starting to rub off on us. Well. we're cheering for you every step of the way!"

Sparkle accented by stomping on his remaining foot, Caelus screaming as the skirt and pantyhose fit his shrunken form perfectly save for the cock still struggling like his spirit, his abs flattening with every strained, begging breath.

"You're getting so soft, Trailblazer."

"Even easier to tease by the second-"

"I wonder if this is your weak spot yet..."

They were getting more sensual with their teasing, hands tracing the contours of his body, teasing his cock, pressure building behind his eyes as he felt like a toy being played with. The breakage of bones and throbs in his cock were equal sources of stimulation, his brain struggling to tell the two apart as the Sparkles continued to stroke and play before the former Firefly had an idea.

"Sparkle, can't you turn that gun back?"

She was busy pushing him to the ground as she shaped his core, giggling with every meaty crunch of his forming curves.

"Oh? What for, it's not like... Oh yes yes! We really should keep progress of this! Let's show him how good a job he's doing at resisting!"

She tossed the gun to her bunny twin, Caelus trying to crawl out from under her but it only took a poke to the balls to make him squirm on the ground with need like a helpless animal.

"I took a few but I think we need something spicier. After all, the Trailblazer would never give in so we might as well have fun if he doesn't want to laugh along."

"Of course! Mmm~ he might be getting softer but his little blazer's still rock solid isn't it? Naughty girl. Trying to act the teacher's pet when you're just a perverted degenerate..."

She pressed a knee against his tender junk, the squeal it elicited sounding utterly girly as flashes of red blotted his irises, the image of her own face so pathetically begging too much for Sparkle as she shut him up with a kiss.

"Good, good! Really let him have it! Ok Trailblazer, fight back! Use that tongue! Don't let that bitch make you feel small!"

He forgot himself for a moment, the role of the dirty schoolgirl egged on as Sparkle continued to snap away, Sparkle's lust-filled scarlet reflected back in his own widening eyes as their tongues mingled, his back arching as he pressed his flat chest against hers almost as a challenge.

Both moaned hot and heavy as the Trailblazer's nipples pressed hard enough to dimple Sparkle's, the last of his seed squirting out in a lust-filled frenzy. His balls were like juiced husks of their former size, squirming with need as something hot pulsed to replace his depleted testosterone, his chest pushing back against Sparkle as the pleasure rose to full elation. He was on the edge, ready to cum out everything, to show this half-baked delinquent how much she'd studied pleasure to make her truly embrace the elation of-

"Now stop! Come now Sparkle, we don't want his mind to pop just yet."

His balls pulsed painfully in their sack, a line of drool bridging their lips as he struggled to continue their makeout session, his cheeks blushed and his lips firmly stuck in a faint, but constant smile.

"Ahh~ wh-what was I- NGGH~! HAA AHHH~!"

Sparkle didn't have enough balls to press so her knee shoved in a few centimeters of cock, the edges of the Trailblazer's smile widening as his tits pressed against the buttoning squeeze of his uniform.

"Having fun Sparkle, what else would we be doing? Oh wait, that's right, you don't want to be Sparkle right?"

"N-No, I mean y-hesss~! Ahh w-wait c-could you make the queeehstion more- GYAAA~!"

Another press and more of his cock was nudged, his core sucking in as he screamed like a bitch in heat.

"That's a good sound, but the wrong answer silly. But keep resisting and look alive, we've got some friends~!"

More Sparkles were appearing, some in torn clothes, some still covered in fluids, all of them eagerly staring as they kept their distance. All Caelus could see were dozens of identical faces, all moaning in the height of elation as the pressure behind his eyes throbbed.

"NNNGH N-No what ahhre you all-"

They just stared and cheered, some of them fingering themselves, others making out as the horde of elated convertees grew. There were so many giggles, so many moans, Caelus trembling as a jealous heat tickled his core. Mirror neurons were sparking, the faint smile growing wider as his own erection throbbed inside the ridged, sunken base of his cock, stirring his hollowed out insides subtly as his nipples hardened. Resist, he had to resist no matter what trickery they-

"Good girl!"

"Keep resisting!"

"You don't want to feel elation beyond the mortal realm!"

"Come on, don't give in even if it feels so good!"

"Yeah, a little longer!"

The Sparkles were cheering him on as they pleasured themselves, Aelusp groaning as his testes continued to pulse against his groin, his cock leaking clear fluids as a weak, sucking tug slowly worked at his shaft. His stomach trembled, like every inch was being teased by feathers, something hot shuddering every time a Sparkle came as he moaned, another sliver of cock sucking in as the last of his bangs gave into her brown color.

"Hey, you didn't want this!"

"Stop giving in!"

"You're the honors student right?"

"Stop moaning you fucking nerd!"

He couldn't help it, Eluspa bucking as his scrotum sucked deeper, nearly all flat, just the barest of outlines not even visible in the pantyhose. His fingers twitched, thinning, lengthening, the urge to use them to tease Sparkle's body and truly feel-

"NNGH GAAAAAAAH-H-"

It took everything not to laugh, the moans easier as his smile turned manic, his palms shrinking, the crowd of Sparkles mocking him as pleasure surged behind his right eye.

"Hey I think this one's a fake!"

"Yeah, the real Trailblazer would never moan like that."

"She's just a naughty girl, isn't she?"

"Yeah, you're one of us!"

Fuck he could feel it shrinking, feel the elation begging to be let out. His brain was ready to burst, h-he had to remember his role- No her elaaation~! Ah no no resist he couldn't resist she was a a-

"Dirty girl!"

"Horny degenerate!"

"Faker, just cum already!"

"Sparkle Sparkle Sparkle Spark-"

POP

Luspar bucked as his right eye's pupil popped into a sakura petal, squealing as his balls shoved inside, bursting into ovaries like girly fireworks as his body was drowned in utter elation. A cleave was opening, drool splattering out as the crowd all chanted their name, Usparkl tearing her stupid glasses off as her cock shoved nearly halfway in as she laughed. Each belly laugh punched her innards hard, easing more and more of it in till it was barely an inch long nub, everything burning, glimmering, sparking as she moaned towards the crowd-

"AHAHAA You're riiiight I'm just a dirty degenerate! Oooh~ teachers won't you finish my punishment?"

She bent over, not even caring which one finished her off as multiple hands slapped and prodded at her junk, spanking and pinching as her cock gushed with every violent caress. She was cumming, another Sparkle squealing as two beauty marks burned into her cheeks, but it didn't matter if they tore at her labia or bit her nipples, pain just a theoretical concept as her little buddy blazed its path before giving its final burst, fizzling into a clit as everything became pleasure, nothing but elation in the whole crowd as all throughout Penacony hordes of Sparkles were fucking and teasing and giggling.

She didn't even remember she was the Trailblazer, her memories far too filled with fake pasts to remember a real one, Sparkle ready to join the crowd as her twins tore at her skirt. Truly this was the best prank yet, but it was far from over.

"Ahhh~ what a perfect lesson. I can't wait to spread this dream to ehhhhveryone~!"
