PUPPY LOVE (CERBERUS FISSION TG) (Patreon)

"I can't believe this! I paid 70 pounds and Amazon bungled the delivery!"

James was whining, looking at the cracked Cerberus statue he had ordered from a specialty shop a month ago. It was spooky season so he had wanted to get something neat since he didn't have many Halloween decorations. He ended up going with a really cool statue of Cerberus snarling, covered in summoning circles and various tiny runes said to be from real occult books.

"Told you this'd happen. We should have just picked it up instead of delivery."

Jack was on his way out, still needing some candy for the trick or treaters, and he was a bit exhausted by James’s whining.

"But it was a two hour drive! I didn't waaant to!"

"Aww..."

Jack gave his roommate a quick headpat, making him blush.

"I'll go pick up something fun for the apartment. Now be a good girl and stay."

"Stoooop! You're not helping!"

James yelled as his roommate laughed, bounding out the door before he could retaliate. Now he was in a mood.

"Maybe I can find the head and glue it together. How could they not ship the head?" He grabbed the statue to move it, ready to look through the packing peanuts and bubble wrap only to cut his palm on the decapitated middle head, the cut small but bleeding profusely as it dribbled over the statue.

"Dammit! What else could go wrong tod-"

As if answering his question the statue started to glow, runes shining a demonic red as the remaining two heads shook ferociously. James dropped it but the statue floated, both heads looking right at him, their eyes glowing. The lights began to flicker, papers were tumbling about in a sudden gust and James just whimpered as the demonic statue erupted in a burning red glow before thumping lifelessly to the floor. James stammered, unsure how to react, confused at what had even happened as the room settled back down. At least things seemed to be normal agai-

"Sister? Sister! Where is sister?"

"Arf dark cramped hmmph! Wanna get out wanna be free!"

"What is- Nngh christ my head m-my head is pounding it's SISTER? WHERE IS- AGGGH!"

It was like his head was crowded, the two voices barking and arguing inside, making him feel claustrophobic in his own body. Sometimes wires would cross as his lips mouthed someone else's words, his right temple throbbing fiercely as he could hear the one girl's voice yelling right inside his ear.

"A-Am I having a mental WANNA GET OOOOUT WHERE EXInngh b-break? SISTER?! THAT YOU? No nooo s-stop it stop-"

A bizarre sort of squirming began worming through his body, twisting in his guts as something wriggled down, stomach distending in uneven bumps like something was trying to get out, a few scratches making him yelp as he was poked from the inside, but even worse was his right hand. It was the cut that had started it, a long tear whose blood had coagulated rather quickly but the edges were throbbing, shaking, something worming through his arm inside the muscle, tenting his skin as the writhing lump reached the cut and pushed.

"Ohmygod ohmygod this isn't happening this isn't- S-SISTER YAY FOUND AN- AGGGH!"

Pain. Blinding pain, the side of his right palm splitting, tearing, two slender fingers wriggling out the cut like some kind of horror movie scene. They were wriggling, spreading open the gash, James feeling lightheaded as the shock of it masked the pain, a third slender finger wriggling out then a fourth, all of them clenching as they pulled out of his cut, the tear racing up his forearm as a girl's clawed hand tore its way out of the side of his own, sucking away mass as it pushed off his arm. There was an awful sounding meaty SCHLICK as more emerged, a soft palm, slender wrist, James crying and whimpering as the more the arm behind it emerged the limper his felt, his mass stolen as his twitching right hand slendered to a matching twin, his palms smoother, forearm thinning as more ripped out. It held his changed hand almost lovingly before yanking hard, James screaming as more tore out.

His voice kept switching between chirpy cheers, annoyed confusion and screams of horror, James begging to wake up from this nightmare as his shoulder blade grinded against his collar bone. It was the pulling, the second arm tearing more of his open like it was pulling off a suit, the lower edges sealing as his shoulder dislocated, then sunk. Another shoulder blade cut its way out, the other arm wriggling its fingers experimentally, James collapsing to his back from an overload of sensory information as he could feel the arm, hear the thoughts moving it, his lips giggling out, "AAAAAAAH HAHAHA FREE HAND IS FREE WILL HELP SISTER AHHHHHHH!"

It kept cuddling against his own, his double socketed joint painfully stiff as amidst the pain his softened, slender forearm rubbed against its match. He felt disgusted at the blush on his face, his cock feeling hard and soft at the same time as bizarre pleasure coursed through the nuzzling conjoined sections. Why was he so horny all of a sudden, god his cock felt so weird it felt like, oh fuck wait the rumbling in his stomach the other voice that feeling traveling lower. No no please-

"OHHH~ OHHH GOD OHMYGOOOOD OHMY- Ooh opening. Think I found a way out."

There was a finger IN his cock, wriggling, probing, James' first taste of penetration causing him to spasm as he could feel something growing behind his cock, squeezing his prostate as his screams veered between horrified and horny.

"Too small. Find better exit."

It had been a brutal half minute, James swearing his body had tried to cum at least five times, her finger slowly sliding back with a wet pop as he gave a pathetic-sounding groan, hips bucking as he stammered wordlessly, finally cumming as he felt utterly spent.

"Maybe here?"

"UHHHN OHH F-FUUUUUCK~!"

Or so he thought, her fingers poking inside his sack, giving his testes each a squeeze as his cock squirted before sliding lower.

"Nooo p-please don't- Oooh~ better! AHHN NO I-I-I!"

He could feel the nails scratching inside, trying to push out below his balls, steadily carving their way out as they tore ribbons of muscle and skin away with every rake of their claws, his skin pushing, flexing, the pain ready to burst.

RIIIIIIP

There were no words to describe it, his cock in a horrific state of forced arousal, tubes and organs all twisting and squeezed as a matching hand to the one working more of its shoulder out now scrabbled about between his thighs, dragging him across the floor as it slowly found leverage to pull more of itself out. This was some fucked dream, some perverted nightmare he had cooked up from reading too many erotic stories online and any moment it would stop.

Yet it didn't, the first hand running over his sides, caressing them gently if awkwardly as it felt around, sliding up. James was rather distracted by the sensation of what could only be described as giving birth and bleeding out as more of an arm dragged itself out, a second set of fingers beginning to pull around the tear, easing it open, inadvertently fondling his balls as the fucked pleasure pain combo continued. He had honestly almost forgotten about the second arm till he felt it feeling up his face, groping around till it wrapped around a lock of hair near the top of his head and tore at it.

It was more than just pulling, the nails digging into his scalp, James screaming as something was starting to rip, the pain in his head growing worse by the second only offset by the feeling of new nerves multiplying and sewing into his mind, a confused buck of pleasure following the torn flap of skin sprouting white hairs as it firmed. It was stroking it, rubbing it, his groans curdling to confused barks as a tenderness that felt better than masturbation made him pant and groan like an animal in heat, the hand slowly shaping an erect, white furred dog ear as it stroked the finished ear before gripping and pulling.

"YENOS ITMYS WORHEAD IS KINGSPLIT TIIIIING!"

His darker locks unfurled to white with every violent tear, a crease forming down the middle of his head as the entire right half of his face distended. HIs eye was stretching, pupil splitting in half before reforming, the bone and muscle replicating as the bones shaved and softened, a cleavage splitting through his brain as it stretched like taffy. Speaking was impossible, a collection of two very different sets of thoughts making his lips fight for dominance, one half of them bloating as the angle worsened, another tug making it so every time he screamed his lips would pucker at one another as if he was kissing himself. With another yank his right eye separated, his face a third longer, two eyes whirling about, both of them slanted, wide eyed, crying as his head looked like some kind of cell undergoing mitosis.

"Ahhhrmosht thrrrr mmph mm~!"

The excited girl voice kept licking, his tongue partially split now, his right nostril feeling stuffed as cartilage replicated and bisected, half the mass of his nose split between the new and old as identical button noses wriggled on a head halfway through splitting. The hand was done with his ear, now grabbing the right half of his mouth, taking a moment to fondle his lips as they plumped before hooking around his cheek and chin and pulling as hard as it could. James passed out from the ungodly sensations of his head sprouting a second one, but the other two were conscious so it didn't stick. Nostrils sprouted and tore, his right eye leaking as it was split not once but twice as half of it inverted, forming a left eye for the sprouting head, his brain unsure how to handle the feeling of sprouting and grinding against itself so it just flooded him with every bit of dopamine and hormone it could.

His teeth were sharpening, jaw splitting, his neck gurgling as words failed. More scalp tore as white hair swirled and spread like a wildfire, flaps of half-torn skin twitching and rising as they turned conical, a malformed dog ear wriggling that was double tipped at the top. Another pull and now there were two half-merged together, his throat spread to twice its usual size, only an illegible gurgle of horrified ecstasy as the spreading head nuzzled more and more with his, smiling, the corners of their conjoined lips separating as their cheeks stretched apart. She was kissing him, James moaning as her playful nibbles plumped the other half of his lips, her eager kissing and licks pulling their cheeks apart.

James could taste his own lips, feel her excitement like an infection as it turned him on too, his body reciprocating as they continued to make out. Her hand kept stroking his all white hair, fondling the single dog ear he had as it stroked and rubbed it, James feeling like jelly as the headpats made his brain throb, their necks nearly split. There was an awkward set of groans and barks as his Adam's Apple rested right between the two, neither side taking it as it ended up sliding out the fissure spot, splatting to the floor as Kirb drowned in her eyes, another throbbing dog ear pulsing up from his head as his overactive hormones kept the orgasms coming. It was half the size of his right, but still ungodly sensitive to her teasing as he remained like playdoh in her hands. She was separating more and more, stealing his mass as she pulled more of her top out, conjoined at the collar bones, then the other shoulder, James's right side crumpling to an effeminate curve as their tongues danced, but the painful crunch between his hips finally brought him out of their intense makeout session.

"FEELS GOOD RIGHT SISTER?!"

"Wh-What are you talking about I'm not- EEEK~!"

James didn't realize quite how far his head had changed, almost a fifth of his body corrupted, his voice coming out identical to the other two, that unbearable narcissistic lust still crossing wires in his head as he had to force his lips shut when the other one talked. He could see overlapping images, his own face fearful in her eyes, her filled with lust, all of it slightly dim minus a crack of light from the one trying to crawl out of his hips.

"Leverage sis give me leverage!"

"KAY KAY SISTER!"

"Wait what are y-oooh~! AHHH AHHHN OHH~!"

The top one pushed herself out further, James feeling his right nipple throb, grind and separate just like his features had, leaving his right a blushing salmon pink, the flesh puckering as Cerberus pushed more of her flat chest out from his. His right arm flailed, more of his frame collapsing, a solid half foot of height sucked into her forming body as her waist separated, still connected at the hips, James's right arm tearing open one final time to release her left.

"YAY NOW CERBERUS CAN HUG CERBERUS!"

She squeezed him, yipping as she ran her hands over his asymmetrical body, making sure to give both of his ears plenty of attention as James found himself panting and barking like a well trained pup. The hands between his thighs were slapping at the floor impatiently, wanting to get out.

"DOING IT NOW SISTER JUST A SEC! HNNNNNNGH!"

James felt dizzy as she exerted herself, muscles spasming outside of his control, his body rolling back and forth as something wriggled above his ass, pushing, growing, tearing.

"MMPH N-NO TAIL AHH WH-WHY DO I KNOW I'M ABOUT TO GROW A-"

A black arrowhead tore through his coccyx, James squealing as a black slippery tail thrust and grew, the new muscles alien to him, yet familiar to Cerberus as she piloted it down to the groping hands of their trapped sister, James knowing what was coming as his hips shattered.

Somehow knowing made it worse, their thoughts and excitement making his mouth keep twitching into a smile, his ears perked and swishing in his long hair, the knowledge of what was going to happen giving him enough time to try to prepare and having all his expectations shattered, just like his hips. Another Cerberus's head was forming, splitting him open, his hips forever fucked as enough room forced its way in to fit her wriggling dog ears, her smirking features and her shoulders as she pulled herself out. The more of herself she pulled out, the smaller James became, another half foot shrunken off his body, his left side curving as his stature went from a bit above average to the twinkiest of femboys.

There was a concave bend to the way his pelvis rested, his cock squirting at random now, the side Cerberus feeling up his new curves as her nipples throbbed, James giving exhausted arfs as the Cerberus below pulled herself out up to her waist. H-He could feel their stares and smug smiles, satisfaction at how the conversion was going, the summoning ritual irreversible due to the broken head, his blood replacing that of their trio, forever binding him to their collective will. And worst of all their joy was overwhelming his fear at that, James's lips moaning, wiggling into a smile even as his pelvis felt like it was being unhinged, even as the pain was terrifying because he wasn't alone in feeling or thinking, and the majority was definitely starting to win.

Both of them gave a mischievous look to one another, their hands fondling James' nip- n-no their nipples uhhn i-it was getting so hard to differentiate. James could feel them rubbing, pulling, more cum sliding out as Cerberus used the lubricant to pull further, nearly out to her hips. Both of them made that face when the top one had grown a tail, James moaning with them as he could feel his chest heaving, breasts beginning to form.

Too much pleasure, too much stimulation, James's mouth switching from one sister's pleasured barks to the other, feeling the fat bunch and firm, flicking behind their nipples as each set of perky flesh jiggled pleasurably, both of them groping and teasing as James couldn't help but follow along, his hands ready to cup... air?

Looking down his chest was still flat, his senses fully hijacked, the sensation of growth just an example of how strong their connected systems were. For a moment he was disappointed at his flatness, the horror of what that meant coming in, only for the next major change to happen.

"Agh my hips are stuuuck!"

"STUPID SISTER DID YOU GROW THEM BEFORE YOU SEPARATED?!"

"Nuh uh! It's just a tight mmgh f-fit ahhn wait I think I-"

"OHHH AH MY BALLS NO MY-"

Thin, boyish hips grinded against his innards, the pain tremendous, but beyond that was the real problem, the emerging Cerberus nearly free as she wriggled her pussy left and right, the sensation of having one already nearly shorting out James's brain before one particular swivel sent his left testicle diving into the tight slit.

"HWAAAA~!"

"HWAAAA~!"

"HWAAAA~!"

All three felt it, both fucking and being fucked, Cerberus's pleasured spasms only worsening it as it sucked the testicle deeper, further, pressure running up the nerves that connected it to James.

"OHMYLUCIFER!"

"OHMYLUCIFER!"

"OHMYG-LUCIFER!"

It plunged, tethers of nerves, sections of scrotum all swallowed by Cerberus’s pussy as her hips broke past James's, the ball deep inside as it began to squirm and probe Cerberus's slit. They were powerless to do anything but take it, James shrieking like a banshee as her boyish hips spread out, a hole sucking down James's still attached testicle as the connection severed, causing the separated nerve endings to rebound as they snaked into his left hip. In a matter of seconds, two ovaries had formed in two different people, felt by all.

"YESSS~!"

"YESSS~!"

"YESSS~!"

Top Cerberus still had some control, yanking on bottom Cerberus's left ear, James's head shooting back as he felt the same grip finally tug it out to equal size, both ears twitching as innards churned and opened. James's had sprouted, Cerberus's had plugged, both of them cumming as the bottom Cerberus popped out first, her legs wrapped around James's left as she humped it needily, working away its hard lines to curves, his foot scrunching between her thighs as nerves connected and James felt his first female orgasm by proxy. It spread across his whole body, his erect nipples humming, his skin singing, warmth flowing inside his spread hips as the nestled ovary began to go into overdrive.

His ass was bloating, far beyond reasonable size, especially his right cheek, the pleasure blocking out any logical part of the three's heads as the separated Cerberus fingered herself from the shared feelings of the two still merged ones. James only realized what was going to happen when he felt a smaller foot inside his right, forcing him to kick, to spasm, his toes tapering with each wave of heat as his mega-sized ass cheek gained an odd crevice down the middle, three even sized segments now jiggling and clapping against the floor together. Another asshole tore open, clawed toes tearing open his foot as his merged partner tried to separate, both groaning and yipping as James could feel her thighs forcing his to inflate, bursting out the side as a pussy began to form.

It was a preview of his future, the bottom Cerberus popping out fully formed, this one having to let it carve a channel open, nerves and estrogen rolling about her right ass cheek and their shared one, a sucking sensation beginning to pull on his remaining ball. Her remaining tunnel carved inside their shared cheek, both bucking and cumming as it strained at their privates, parts never meant to interlock struggling to resolve the internal clusterfuck as their shared ball tried and failed to slip inside.

They needed to separate, even his tail maddeningly interlocked at the base, splitting apart unevenly like some kind of planarian as the throbbing tails coiled and rubbed one another, working their systems into a frenzy. They kicked, identical feet pressing together, trying to push the other apart, their ass cheeks trembling as the tangled caverns of James's vas deferens and Cerberus's own tubes kept them locked at the hip, James certain this was it for his mind as the two yowled to the hells for relief.

It was the separated one who ended up resolving it, thrusting her tail deep inside her own pussy, James and Cerberus both bucking as new muscles clenched and pulled, James's ball sucked in and bisected as the two finally separated, his cock spilling the last seed he'd ever make as a man.

He slumped over utterly exhausted, certain it was over. It had to be, the two demon girls successfully born, their separation not complete till there's three of us silly. He stared at the two sisters as they smirked, back to back, panties and undershirts forming over them as they giggled.

"Huh? B-But c-can't I keep my mind? I mean I'm Cerberus~!"

"Cerberus~!"

"Cerberus~!"

They spoke in sync to show how easily they could override his mind, snapping their fingers as a matching set of panties and undershirt formed, James trembling at how aroused they were at becoming complete, his cock rock-

"HARD!"

Top Cerberus giggled, feeling up his cock as black gloves formed over all three's hands, suit pants next to appear as they slotted well atop James's hips.

"Flat..."

Bottom Cerberus rubbed at his nipples with a gloved hand, palming the still shapeless pec, James whimpering like a lost puppy as the two began to rub him.

"P-Please I'm a Demon~!"

"Demon~!"

"DEMON~! AND YOU KNOW WHAT ELSE WE ARE SISTER?"

"Triplets. Don't you want to be-"

"Complete sister? Ah no s-stop putting words in my ahh~ ah g-haa aaw L-Luuucifer?"

It burned to say god's name now, or maybe he was just hot from being the center of a Cerberus sandwich, the twins fondling and stroking their lost pup into a proper triplet.

G-Getting harder to think, James feeling the hand on his cock and nipples like they were his own, feeling as he nuzzled his own face? N-No he was stroking his sister's cock ah fuck w-wait t-tweaking his sister's itty bitty-

"HWAAA~!"

They were rubbing all over, squeezing him, James feeling just how short he had become as the two girls easily dominated him, petting his ears as they kept calling him sister, making his lips repeat the words as his chest began to rise.

"PLEEEEASE I-I'M YOUR SISTER STAHHP NO OHHH~!"

His breasts were rising, each hitched breath in finding more and more jiggle, more squish as they rubbed against his sis- nngh c-corrupters' bodies. H-He had to fight through the haze, two sets of thoughts swimming in his mind, how fun this all was to make himself give in, James grunting as he came at the thought of making himself Cerberus. His cock was being stroked with more force downwards, easing it in, his chest swelling further, bouncier, rounder, his nipples rubbing against one of theirs as for one blissful moment his mind couldn't tell the difference, so much shared, so much the same a constant feedback loop of-

"GAH GET OFF MEEEEE~!"

He pushed them off in a final burst of strength, praying the connection would fade over distance, desperate to-

"CUUUUUM~!"

He toppled over, screaming as top Cerberus thrust three fingers into her pussy, James screeching as the sudden hard fucking made his cock compress, another feedback loop of pleasure starting as he landed on his newly perkened tits.

"AHHHHRF~?!"

"AHHHHRF~?!"

"AHH AH S-SIIISTER NNGH OOH I TH-THINK IT'S ABOUT TO-"

All three of their tails sprung up, James's cock sliding against phantom fingers, all three feeling it as his shaft was pulled apart as it sucked inside, lining the walls of his widening pussy as each inch was its own building orgasm. All three fell to the floor when they felt it pop, a chorus of barks, moans and screams filling the apartment from a shared cock inversion.

"B-BAD SISTER!"

"You stole our fun!"

"Ahh cahhhn't thiiiink oh fuuuuuuck ahh i-it's so weeeeet~!"

They dragged their moaning soon to be sister to the central couch, undressing as they moved, tops pulled open as they each grabbed James by a leg.

"NOOOO I'M SOOOORRY I'LL BE A GOOOOHD GIIIIRL JUST NOT THE INFINITE LOOP~!"

"INFINITE LOOP~!"

"INFINITE LOOP~!"

They spread James's legs open, theirs following as they slid their slits together and pressed. Next were their tits, the other two keeping James held tight as they formed a triangle of endless pleasure, their bodies shivering as the warmth began to build.

It only took a minute for James's mind to start to break, feeling Cerberus's slit against Cerberus's against Cerberus's against h-his? Hers? Ah no th-they were the ones grabbing Jamus or was that her a-all three visions were shared all that heat of their heaving, sweating bodies rubbing and touching and bouncing ahhh ah fuuuuuck. Someone was screaming w-was it Cerberus? Oh ohh h-he was cumming ah but his cum was shooting into himself or was it his sister or her other sister oh god oh fuck Cerberus's nipples kept rubbing Cerberus's which kept rubbing Jamerus's-

FUUUUCK OH FUUUUCK OH GOD WHO WAS SCREAMING WHO WAS CUMMING IT KEPT LINKING SHE WAS MELTING MELTING AHHN AHH CERBERUS WAS FUCKING CERBERUS FUCKING JERBERUS FUCKING CERBERUS FUCKING CERBERUS FUCKING CERBERUS FUCKING FUCKING FUCKING CUM CUM CUM ENDLESS FUCK FUCK HAAAAARDER!

Cerberus shoved her tail into the sister to the left's pussy which she reciprocated which she reciprocated which she continued as Cerberus's pussy spilled over into Cerberus and Cerberus, Cerberus's chests really scraping against Cerberus and Cerberus while Cerberus's tongue really did a number on Cerberus who Cerberus Cerberus Cerberus Cerberus Cerberus

"YESSSSS~!"

"YESSSSS~!"

"YESSSSS~!"

Cerberus and Cerberus and Cerberus collapsed as Cerberus and Cerberus and Cerberus came.

Jack meanwhile was stuck in traffic, annoyed that a twenty minute trip had turned into two hours but it happened. Hopefully James wouldn't still be moping when he got back and they could enjoy a movie or something. As long as it wasn't about that stupid statue cause the last thing he needed as he got to their door was any more-

"Hi!"

"HI!"

"Hi!"

"Uh... hi? Did I get the wrong- wuhoooah~!"

The triplets pulled him, the one in the middle smiling the widest, one on the side a bit timid, the other with a fainter look of smugness.

"SO YOU CALLED SIS A GOOD GIRL IF SHE STAYED RIIIIIGHT?"

Was, was he on like a prank show? Why were these three hot girls surrounding him? Wait what happened to their apartment the living room was a complete-

"GWAAAH~?!"

One of their tails shot into his ass, the other through his pants to slot into his cock tip, the third plunging into his navel as their incisors all nipped away at his shoulders, something hot flowing in, his blood dotting over James's broken statue as it began to glow.

"YAY SISTERS MASTER IS GONNA COME!"

"Good girls need a good master don't you agree?"

"Aww I think his brains are already scrambled. Well, any last words Master Modeus?"

The room was spinning, Jack's body on fire, his hair spilling in thick clumps, his body trembling as he was teased and petted, a thick red sludge gushing from his cock as it formed leggings around his trembling thighs.

"Th-The tails are REEAAAAAL~? AHHN AHH LOOOVE OH GOD BRAAAIIIIN UHHM AHH G-GOOOOD GIIIIIIRL~?"

Oh god something was filling him, changing him b-but screw all that boring side filler just get to the part where her cock-

"YESSSSSS~!"

Modeus collapsed as the Cerberus triplets pleasured her, her eyes spreading to hearts as her form curved, committing every moment of her cock's collapse as she lost her virginity to herself... well theoretical virginity, sh-she was just so horny all the time, so needy, her pussy so wet as the triplets continued to rub her, black horns poking out as she came away her past self.

"Alright Master-"

"MODEUS YOU'RE THE ONLY ONE WHO-"

"Can keep up with three girls-"

"At once! So Master-"

"Do you think you're up-"

"FOR HELPING US BE-"

"Good girls?"

"With good girl rewards."

"AND LOTS OF FUCKING!"

"Yes but I think of all people-"

"Modeus knows thaaat~!"

It wasn't like she had much of a choice, all three dog girls almost feral as they groped her, panting with excitement.

"I'll t-try my best?"

It was a very loud, very eventful Halloween night for all.
