Fluff Endemic
In preparation for a Monster Hunter convention a couple and their dog use transformative magic to formplay as several monsters- but to avoid being harassed for choosing an unliked monster, or picking the same monster as someone else; they pick small monsters. Their choices unintentionally create a theme of a LOT of fur.
(M tf F Gown Goat, F tf M Wulg, Dog tf Marionette Spider)
Eli uses an app on her PC to put together a spell array for her dog Lewis as he sits in his lap happily panting and wagging his tail- not understanding what the spell will do for him but still acting as an emotional mirror, reflecting the energy of his masters. Eli's boyfriend Sven is sitting on the couch in the living room, only about ten feet back from the PC, watching what Eli was doing over her shoulder.
It is almost the Monster Hunter convention and not only will Eli and Sven be using formplay spells to take cosplaying to the next level- even Lewis will have a new body to attend with! Eli is a woman of average build- quite pretty but nothing especially noteworthy either. She has base blue eyes and straight brown hair to her shoulder blades and B cup bust. She is fit but not at all muscular. Sven is a bit on the chubby side but not quite fat. He has earthen brown eyes and short combed back black hair. Lewis is a scruffy terrier; his entire body a little bigger than a football, so he is easy to bring with you- you can just pick up and carry him.
Formplay is a type of transformative magic that gives you the body of characters from shows or games that do not exist in the real world normally. Originally they were made of hybridizing the traits of actual animals and then using makeup and practical effects to adjust them- so sort of a halfway point between current formplay and old school cosplay. A lot of people love using it at conventions though, so there was a lot of people working with the magic to refine it. Now not only are they able to give you fully functional fictional forms- some of them also enable fully functioning fun bits for frolicking and fornicating. Yup; real-life fictional characters with working sexual anatomy, oh what a future we live in! Of course, letting Lewis keep his bits in a public place might be problematic, so Eli chose a genderless version. He is fixed normally- but if she used a male specific form it would actually temporarily restore his nuts, so... best not do that, so he doesn't jump someone else's pet. Or since half the people there are likely transformed into a creature themselves- jump someone who was normally human, not knowing better.
Sven sighed a bit nervously, even though he was still grinning. "Well? About done?"
Eli spun in the chair to face him. "Yea, basically. Eager to see me transform, hmm?" She pointed at him and her expression became stern. "Remember, Congalala was off-limits. If you turn me into some foul airbag monster..."
Sven nodded. "Don't worry; I value my life. That isn't to say I went with an... interesting choice."
That was the surprise this year- Sven and Eli did not pick their own formplay; they chose each other's. Eli stood up, and Lewis plopped down onto the floor and started to dart around the room- excited without even knowing what he was excited about. Eli was about to unbutton her shirt but Sven stopped her.
"You probably don't need to do that."
She cocked an eyebrow. "Oh?"
"Well here is the thing... people have strong opinions about a lot of the main monsters because, well... you spend the entire game hunting them, so you either love them or hate them. You don't want haters coming up to you during the convention and trying to make you feel bad about what monster you like, yea? I also did not want to choose one of the more universally liked monsters though because chances are multiple other people at the convention will already be doing it already, making it redundant. Sooo, I chose a small monster."
Eli gasped and smiled at the same time. "So did I! Oh gosh- I hope we did not both choose the same creature, haha."
They both held up their cellphones- the transformation runic array already displayed on the screen. They both stared at one another with a mischievous grin and nodded at the same time, signaling the other to activate their change at the same time!
They both shivered immediately, feeling a subtle tingle through their entire bodies from head to toe- but Eli's remained a tingle to her toes, while in Sven the sensation became a bit stronger the further down it went, almost feeling like being gently poked by a million fingers for a split second. Neither knew what they would turn into, leaving the changes themselves to tell them what they will become.
Sven scrunched his face up, furrowing his brow at the sensation of a gentle but insistent pressure on the front of his skill. After a moment it concentrated into two points over his temples and then surged forward! The bone welled up and expanded into two lumps, stretching the skin tight. The color left the skin as the blood was forced out from lack of room before the bone mounds under it started to become slightly more pointed and immediately broke out of the skin! The blood had already been re-routed so the broken skin did not bleed, just simply stretch wider open forming a few taut folds at the base of the forming horns. The horns grew almost straight back without even projecting out from his head, causing it to push his hair out of the way and then the hairs it passed over fell away entirely- the horn followed the curve of his head exactly.
The horn paused its growth and there was a sound almost like groaning wood as the base expanded wider and then a smaller horn slid out from the expanded portion, getting longer again. Multiple tiers? Ribbed horns, like a caprine. He also felt a surge of movement down his spine as it prepared to grow, giving him goosebumps from the feeling.
At first his spine lengthened, pushing out into a proto-tail which felt rather cramped and pulled the skin uncomfortably tight, but then with a surge the muscles of his lower back branched and shoved themselves around the bone to be a better buffer between bone and skin. The tail seemed to be growing at a good speed, so probably an impressive one. He felt muscles seem to tighten in his upper crotch as well in the front oddly, then a slightly pleasurable pressure building there that made him blush.
Eli across from him also felt an impressive tail growing in rather quickly as her first change. It shoved its way down but her panties forced it forward between her legs and against her pussy, making her blush and squirm , pulling her pants and panties away from herself in the back to try and pull the tail out. Pinned against her by her clothing- the forming tail could not free itself. She did not even notice a stripe of black fur growing on her forehead in an arrow down from her hairline! Her ears shrank a bit, becoming rounder and quickly getting covered in black fur as well- the skin on their insides turning the exact same black!
Eli staggered back a step and had to brace herself on the back of the chair so she could pop her hand right down her pants to actually grab the tail, because now it was overfilling her panties and every time she tried to move it under its own power she unintentionally caused it to squirm firmly against her pussy, unintentionally working herself up! She pulled half of it out at once and had to re-adjust her grip to pull the rest out, as the tail is STILL growing. There is a layer of fur growing on it as well from the base out, but it is just a fine, powder soft fuzz at the moment- barely just starting to grow. The tail is already half as long as her legs and doesn't seem like it is going to be slowing down!
Eli is breathing heavily, feeling her clit twitch from the unintentional stimulus; but after a few moments it felt unusually tight even when it wasn't clenching! The skin started to itch a bit from internal pressure and the clit jut out of its hood, starting to take a soft point to it! Oooh, that isn't from the tail- it is actually changing! Eli furrowed her brow at Sven who chuckled nervously in reply, even as his face was still scrunching up from most of his more intense changes happening on his head first. What has he done?
Eli arched backwards over the back of the chair, holding herself up on it as her eyes widened from a feeling of pressure centralized on two points deep in her guts! There was a subtle groaning that could be heard as her womb suddenly shrank and seemed to collapse in on itself as her ovaries engorged massively in its place! The bigger, heavier ovaries sank lower in her as they mutated toward testicles! That fucker! He used a male gendered transformation!! Sven has always had a thing for futa- especially when they just turn half-gender, because then they do not know how to deal with their new appendage and end up being somewhat controlled by it as a result. So of course this would amuse him.
Eli was breathing rapidly now as she glanced down at the bulge under her pants snaking its way up toward the waist, pinned between her and the cloth prison. Her womb vanished entirely and the vaginal passage shrank as the balls grew inside of her and sank lower, smothering the passage to fight for room. For every ring of muscle that vanished from her vaginal passage, a new one formed in her clit. Her urethra stretched out from its base to follow it up! She breathlessly bowed forward and yanked her pants and panties down in the front to let it out when Eli already felt pre bubbling up out of it and lubing her panties.
Eli winced and cried out in brief pain- her testicles ran out of room and the path narrowed the further down it went, causing the two spheres to collide with one another! It was like two people trying to get out of a doorway at the same time and getting stuck. Her labia clenched and fused together, knitting together a scrotum in anticipation of catching her descending nuts. The very top of the labia however pursed up to the mutating clit and fused to the underside of her clitoral hood on either side- so that the skin formed a complete ring now and the pleasure receptors in it started to dull as the skin tone cooled from the normally neon pink- it is becoming a sheath.
Eli scoffed at Sven across from her. "I knew you wo-oohuld try something like this when you sugge-eeh ah! S-suggested we pick each other's form."
He shrugged. "I just thought it would be cute to see how you would react. Not like an--nnnnghyone else is going to be... lifting your legs to look at your junk at the convention so it doesn't matter in that context." The pleasure is growing in his groin, causing his dick to erect itself.
Eli just grinned wickedly, nodding toward him. "Then I guess you won't mind."
"Huh? Wait- what?!"
Sven quickly pulled his shirt up to see what the pleasurable feeling and tightness was in the front. He had thought it was an echo of all the activity growing his tail out, but that wouldn't be felt on the opposite side of his torso without any sensation between the two points. What he seen were two almost perfectly round hills pushing out of him on his upper crotch! At first he thought something was growing inside of him but there is no inward pressure, only outward... it isn't growing IN him, they are growing ON him. When the skin bunched up and started to darken, popping out almost perfectly centered on the hills he immediately recognized them as mammaries!! Well that sure as hell narrows down what he could be- there are not a lot of mammals in the Monster Hunter universe and dragons generally don't have tits. Eli predicted him gender swapping her- so she also gender swapped him! The biggest hurdle in learning how to hunt a monster after all, is learning how it acts and reacts- and cutting it off before it can.
Sven was going to protest but he sort of dug his own grave on this one by already having done the same to her. His tail had been growing down his pant leg, but now his leg was forced straight and the tail was still poking out the bottom by at least a foot and it is still growing, though starting to slow down now. It is covered in pale grey fur that is also still growing, even though it is already three inches long! The fur seems to shift color though- at the very base where it overgrows his pants slightly in the back it looks like pale gold- a platinum color, but then quickly shifts to an extremely dark blue-grey that looked black except where the light shines off it. Afraid for his poor manhood and having his tail vastly overgrowing them anyway- Sven undid and shimmied his pants off without getting up from the couch. His dick sprang out fully erect, completely ignorant to his worry. The forming tits in his crotch swelled bigger and plumper, eventually meeting in the middle- they are joined together... an udder. The skin on them also turned completely black at the nipples and the coloration slowly faded in over the rest of them too.
He was quickly distracted, looking across to Eli as she moans loudly and leans forward so suddenly she almost collapses! The chair has wheels so when her weight leans too far on it, it just slid out from under her, then several wheels left the floor and the seat of the chair hit the bottom of the table- thankfully the table caught them both and prevented her from tumbling over completely. She moaned so long with such a desperate tone that Sven thought she might black out from lack of breath. Her mutated mega clit was now a tapered grey-pink penis, but started to twitch and throb frantically, oozing pre almost constantly! One testicle and then the other finally forced their ways out into her already formed scrotum. Both scrotum and growing sheath though were both candy pink and black at the same time, mottled. She did not stop moaning when her nuts popped out though so that was not the problem. He could not see what was happening outwardly- just an odd throbbing at the base of the shaft.
There was an audible squelching as her sheath was forced wider suddenly, then even wider... then even wider than that. There was something MUCH larger than her dick in there! It made a loud *shluck* sound when it finally managed to bombard its way out of the sheath far too small to house it in the first place- a four-pointed knot! Though the end of the phallus is tapered, its based is adorned with a canine-like knot. The shaft itself once fully formed is about eight inches long, but the tremendous knot adds another two inches at least and is easily four times the width of the actual shaft. Taking the shaft is story mode- taking the knot is a challenge quest. The knot indents steeply in the middle sectioning it off into four parts rather than two; looking like a grey-pink four-leafed clover if you look at it top-down. The spurt of pre Eli shot immediately after it popped out almost made it across the room to Sven! She gasped hard and then her entire body trembled at the pleasure from it being released. Generally it pops out fully BEFORE the knot is 100% engorged like that. Also the knot is so enormous that even fully out the sheath is smashed as far back as it can go by the steep curvature of it, so any movement of the shaft causes its own sheath to loosely suck on the underside of the knot- which is by far the most sensitive part of a canine phallus.
Sven looked down nervously as he felt the growing weight of the forming udder resting against the top of his shaft. His penis bucked, causing it to rub itself against the soft flesh of the udder cleft. He pressed down on it lightly to hold them still together but ended up thrusting gently against it while his hands held the udder in place! The hair on his tail was almost a foot long now and still growing! His tail itself is almost half again as long as his entire legs- that is an extremely big tail. Because the fur was so rampant on the tail it started to creep up his back now too, forming an arrow shape as it grew from his spine first before spreading out to the sides. His face had never stopped changing either, though progressed relatively slow in comparison to everything else. The skin of his forehead darkened as the keratin level increased and it hardened into a ridge, which was pulled out as his horns grew, causing their third segment and each section after that to be united in the middle by a plate straight across! This also started to progress DOWN now too- causing the skin to harden on the bridge of his nose, layering itself as it grows too hard to flex, and putting a pressure on his nose like it was trying to pull it wider!
Eli felt her hands and feet surge in growth, stretching them longer and she wobbled in place and finally fell forward, landing onto them. The nail polish on her fingernails cracked and broke off as her nails narrowed and lengthened into sharp claws- turning a dark translucent grey. She bowed her legs, putting her butt close to the floor as her dick bobbed fervently in the front, and the fur on her growing tail exploded in volume! Her tail is as long as her legs too, but was slowing down- so it would not be nearly as big as Sven's. The fur grew out and was pulled mostly down from its own weight, but remained fluffier and rounder than Sven's- his tail alone thanks to all the fur on it probably weighs almost as much as the entire rest of his body. Eli lets out a sound that is almost a growl as strands of her hair fall out- shoved out of the way by fur that formed around its base and then advanced into it. She was gaining two colors however, like Sven- the fur forming on her head is pitch black, but the fur on her tail is snow white.
Eli was distracted though, with how hot Sven growing and udder is. His blushing face, how he squirms in pleasure, thrusting his dick against his own tits. The transformations do not affect the mind in any way... at least, not directly. Swapping genitals however means Eli is now being flooded with testosterone and Sven is drowning in estrogen. Her pants flipped back up from under her junk but by the time that happened her balls were big enough to fill the front of her panties on their own- preventing her clothes from trapping her dick again. She walked awkwardly across the floor on all fours- though her limbs were not structured correctly to do that yet so her movement was a bit off. Sven did not notice her till it was too late. Her head came up between his legs and opened her maw- revealing her teeth are all sharpening into fangs as she latched onto one of the teats on his udder and started sucking! She held on tight with her lips and used her tongue to flick the teat back and forth rapidly. Both teats started to grow both longer and fatter from the stimuli!
Sven was too busy moaning to protest or try to knock her off. She remained on all fours on the floor so to latch on- she is pulling the entire udder down a bit, which is causing the bouncy smooth skin to rub into his dick! The udder gets bigger and bigger, and in spite of remaining exactly as hard as it was- his cock is getting smaller and smaller! The udder got heavier and wobbled more energetically as Eli sucked- the flesh now entirely glossy black! Each teat like a fat cone on the end. Sven could not even see his penis around the curvature of the growing udders now, but he could still feel it sliding back against the udder as the udder itself slid further out. His penis was only four inches as his balls regressed from the size of a large chicken egg to a ping-pong ball in size!
Eli used a deformed, elongated hand to cup his balls and taint, rubbing them gently just by crooking and straightening her fingers. Sven groaned and gasped, feeling his insides get a little gurgly and shift around, preparing to make space for a womb! Each segment of his udder now surpassing the size of a cantaloupe, the teats as long as his pinky finger and twice as thick! His penis now regressed to only two inches long, and his balls the size of grapes! From the inside out, muscles formed and gave structure to a forming path, a vagina for the womb. Each segment of the udder the size of a watermelon as they stopped growing- though the teats continued to tingle with electric pleasure for a few moments, stretching to the length of his entire hand- wrist to fingertip. They are almost the exact proportions of a large icecream cone, except squishy and rubbery. That is an ebon goat udder!
Eli went to grab the free-hanging teat to twist and roll it between her fingers but stumbled forward, causing her to unintentionally yank on the udder and mash her face into the upper curve to catch herself! Fat deposits started to swell out under her hands and feet with enough force that they shoved her up, forming into plush black pads on her extremities, but also throwing her completely off-balance for a moment. Eli yanking down on the udder mashed it even harder into Sven's shrinking manhood, causing his balls to pop inside of him and yank up, turning to ovaries! As they pulled up the skin and muscle tightened and pulled inward too, collapsing into the vagina already forming under the surface! Because Eli had a demi-paw already massaging the scrotum and taint, her fingers immediately sank in and split the scrotum as the skin fattened and formed into the labia instead! When she tried to stand onto all fours properly again she unintentionally put too much weight on that limb and her entire hand shoved into Sven causing him to go cross-eyed from the sudden sensation of being penetrated for the first time... and with zero warmup.
When Eli's tail swished; it is so fluffy you can feel the breeze created from the force of it moving. Sven's tail is so enormous and ludicrously fluffy that he can't even lift it! The fur spreads so far out on either side of the tail that it almost looks like there is a smaller carpet under them. Flecks of bright yellow started to appear in Eli's normally blue iris- though Sven's brown eyes remained brown; his pupils instead shifted. His pupils started to deform, stretching wider and less round, becoming rectangular! The bridge of his nose popped and he unintentionally let out a bleat! His nose became almost twice as wide- finally succumbing to the pull of the armor plates that were growing down it right to the tip! What had started as horns was now more of a multi-layered plate over his head, covering where his hair used to be- forcing it to fall out. The plate had a slight point in the middle and a ridge that extended beyond the back of his head but only slightly- and then two points along either outer side, which is the actual horn formation. There was still a pressure in his nose even now though... except now it is threatening to yank it longer.
Eli licked and sucked almost frantically at the wobbly black udder, going from one teat to the other, pulling her wet demi-paw back out of Sven's new pussy to help steady herself. What had been his penis shrank even further without the balls to accompany it, regressing to one inch hard- now utterly buried in its own foreskin, then only half an inch when his entire pelvic floor collapsed into a new vaginal passage. The labia splitting and properly forming caused the foreskin to also get yanked back and part at the bottom- the remaining bulk at the very top now a clitoral hood! The urethra regressed back and flattened out onto the surface of the inner vulva over the vaginal passage, and what had been the glans- the only part of his penis left since the shaft shrank completely out of existence- is now the glans clitoris. No urethral opening, but not actually that different in shape from when it was part of a dick. It is functionally the same thing.
Eli's made a growling sound again and then a yip as her hands and feet made muffled crunching sounds as they reformed- since the tissue insulating the bone is relatively thin there so it can't silence the sound. Her feet became long and narrow- her toes bunching up as well as becoming wider and a bit shorter, making it impossible to spread them very far out. Nearly the same thing happened with her hands, except her thumbs regressed back as the rest of the hand stretched forward, becoming a mere dew claw.
Sven furrowed his brows at her shirt, thinking at first her breasts had somehow both grown and also fused together- but then he realized he wasn't looking at a boob at all. Her breasts have actually regressed into nothing at all- even the nipples stretched flat against her chest, but the coloration of them darkened further to black rather than fade, and then the darkness spread. What Sven mistook for a mono-boob is actually a growing bush of fur! Starting from her cleavage, a massive tuft of fur grew as her tits shrank and now it was both growing longer and spreading wider to consume her entire chest- and filled her shirt in the absence of her breasts.
She looked confused a moment herself, arching her back and then cooed in pleasure as several of her vertebrae popped loudly- but then looked startled as they started to pop in rapid fire without her doing anything else! Her spine was stretching longer! Her tail was getting a tiny bit longer but more distressingly both her neck and torso were also getting longer!
"W-wulg!" Her voice had a deep grumble to it now, making everything she says sound like a sort-of growl.
"Ye-e-e-e-e-eh!" He meant to say yes but his face immediately went red when all he managed to do was bleat like a goat in heat.
Wulg are opportunistic hunters- carnivores that only hunt in groups; they will not attack you if they are alone because they know they won't win. If you run into a group of them, or a larger monster is downed while they are around- they will take the chance to bite off whatever they can and then run again when their target recovers their footing. They are small enough that they can climb onto a person- wrapping their long bodies around the target to both attack and evade while essentially riding their prey, making them hard to knock off. They are still large enough however that a human can mount and ride the wulg as well however. Their extremely bushy and soft fur is because they make their home in frozen tundra.
Eli kept having to put her paws further up the couch along Sven's legs because her back was already arched back far and it kept getting longer but she had no room with the couch directly in front of her. She awkwardly rest her head on the top of his fat udder, her eyes rolling back at the feeling of the soft, hot, rubbery skin squish out under her chin. She was making micro-thrusts with her hips, her cock almost painfully hard, and shiny from all the pre it was flicking all over. The phallus- especially the knot- was covered in very thin but very visible violet veins. Her testosterone poisoned brain smelled pussy with her increasingly sharp sense of smell and she scrambled up Sven suddenly even as the popping in her spine was only just slowing down and thrust into him!
Eli had to now arch forward quite a bit because her body was longer than Sven is, as she thrust into him frantically- though not the knot... yet. The udder clapped softly against her groin as she thrust into him and she looked down at it, mesmerized as it entered a jiggling fit with every thrust. Sven just moaned and grabbed the growing fur on her chest, gripping it tightly for only a moment before he bleat again and his hands started to crack and crunch! His hands and feet were changing now- but in a completely different way. Rather than simply get longer, the bones were both getting longer and thicker, causing them to shove into one another and eventually fuse, becoming one huge bone- a cannon bone, of an ungulate. He held his hands up between their chests like a puppy dog's begging stance, and both watched them devolve. Thumb and pinky regressed, getting much shorter, losing a joint and the nails thickened and darkened so much they turned to pyramid shaped mini-hoof segments, the dew claws of an even-toed ungulate; cloven hooves. The index and ring finger grew in size but also simplified in joints and the nails became even more giant compared to the digits. The central fingers and toes regressed- devolving into absolutely nothing as its biomass was fed into the digits flanking it!
"Wha-a-e-e-h? Wha-h-haaht aa..aam I?" He was really struggling not to bleat and failing- admittedly that was more to do with the searing hot dick slamming into him than his actual physical ability to do so.
"Grrrow- g-grrrr, reeh..." She cleared her throat. "Gown Goat."
Gown Goat are herbivores- they will run at the first sign of danger as they have absolutely no combat prowess whatsoever. Their billowing, extravagant fur however allows them to slump themselves over and imitate the appearance of a boulder at a distance- and the mothers will use their gargantuan billowing ball-gown looking tails as a curtain to cover their kids, shielding them from view entirely while they still have access to her udders.
Eli grinned with her mouth full of fangs and put her paws up onto the back rim of the bone crest on Sven's head, and used it as a handle to pull herself further forward, ramming her knot into his pussy! The phallus of a Gown Goat is already not especially impressive, so a Wulg dick is already pretty damn good size for that opening- the knot is absolutely behemoth. Rocking her hips while she thrust into him, she managed to get a third of the knot in several times- but as soon as she tried to shove more of the knot in the part she already had in popped out. But the more she rubbed and shoved into the opening the more the skin stretched, and the more lube their combined genitals made.
Eli's own fur was spread spreading up her entire back, but also down from her head onto her longer neck. A separate patch formed on its own on her upper back to help link the two trails, and on her back the fur became so bushy that it almost made her look like she has a hunch back! Gown Goat fur is very long but it is also rather heavy- Wulg fur is very soft and long, making it bushy and fluffy looking. The backs of her hands and feet were getting furry now too. The thickest and bushiest fur on her is on her chest and back- but there is no place on a Wulg's body that isn't at least a little fluffy. The seams on her shirt were bursting not because of her size but because of all the fur trying to cram itself into it- making it look more like a pillow than a top. In all her thrusting her pants and panties slid a bit more down with every thrust, so they have long since fallen to the floor, forgotten. She is still technically wearing her bra too, but... it's effectively doing nothing.
Eli's eyes were half blue and half scattered yellow, but flared in surprise and the reflective yellow suddenly expanded, consuming her entire iris. With an almost *plunk* sound her brutally enormous knot finally popped into Sven! Once it got past the halfway point the roundness of the knot caused it to yank the rest of the way instantly! It was a bit too sudden for Sven who flinched in momentary pain, bleating again.
Sven's own body was being utterly consumed in fur now too- it already connected up his entire back, though you wouldn't know since he has been lying on his back the entire time. His spine popped and his neck lengthened, though not to the extent of Eli's neck. Platinum colored fur grew out from under the lip of the bone crest and covered his neck. Plumes of platinum fur grew from his fetlocks and just like Eli- he grew fur from his chest in great volume; though from his chest it is the raven black that took most of his tail. Long fur started to grow from the backs of his ears, which almost cloaked the fact that his ears were actually getting longer themselves! They were not structurally sound at all, and immediately flopped over, and as his ears grew longer they took on a loose spiral shape- like the ears of a Damascus goat, only with long wavy platinum fur on the outer side.
Eli loved teasing, and every time she felt the tremors of a female orgasm vibrating through Sven she would slow down and instead see how far back she could pull slowly before her knot actually started to slide out- shoving it back in fully before it got to the halfway point. She was really starting to pant though from the body heat building up under all that fur- Wulg live in the arctic, not houses. Her tongue became slightly pointed on the end, and she grit her fangs again as a dry grinding sound could be heard from inside of her head- her skull itself is stretching out, giving her a muzzle! She arched her upper body back a bit and all the buttons exploded off the front of her shirt all at once like a shotgun blast at Sven! Eli's body has actually gotten slightly smaller- so her shirt was entirely overloaded with fur alone!
As her face stretched her lips turned glossy black, as well as the tip of her nose which expanded to face forward. Wulg have pointed faces and rather subdued ears- which thanks to their heads being utterly black; you usually cannot see the ears at all. The entire head, a long diamond shaped stripe on the back, a thin stripe down the front of their neck and ending at their chest, their entire lower limbs from the wrist/ankle down, and a thin stripe of fur from their elbow and up over their shoulder; those are all the places on a Wulg that are black. The entire rest of the creature is snow white. The reflective yellow eyes really stand out in the utter darkness that is their head.
As Eli's transformation was completing her pleasure was spiking- she tried to tease back but it wasn't working- that part of her dick is the most sensitive and she was already too close to edge back now! With her newly formed muzzle she lunged forward and bit Sven's neck, digging deep enough to cut through all the fur and leave red marks along his neck with the tip of her fangs. The massive four part knot throbbed in time with the jets of cum as she filled Sven up. With Eli collapsed on top of him, his udders were squashed between them- the massive fat teats jutting out from the fur on either side of Eli's very long midriff. Fully transformed, her shirt remained on but only held in place by the sleeves, since all the buttons are torn off the front it cannot be closed. Her bra already worked its way loose, so it was sort of just free-floating in there till the shirt burst, and then it fell away.
The longer Sven's fur became the more wavy it became, and just like Eli it completely filled his shirt, billowing it far out in the front and starting to poke out gaps in the seams! Unlike Eli however- he did not grow fur on his back. Most of his arms and legs, his entire backside, and almost the entirety of his face never grew fur- Gown Goats are bald there; instead platinum colored scales grew to cover these patches! The scales are slightly rounded and overlap one another so they project off the hide a bit, but are not sharp in the slightest.
His entire body grew a bit, causing his shirt to groan even more and bushels of long raven fur slither out the expanding gaps as the threads in the seams start to snap one loop at a time. Eli smiled and placed a paw on his chest, shoving back into the fluff, but then extended one claw against the shirt. The moment her claw point touched the shirt- it completely exploded, blowing off him like a burst balloon! The long wavy locks of raven colored fur on his chest unraveled after being freed- easily over a foot long! The fur tapered off on his midriff but then suddenly increased again in length at the base of the udder! Unlike a normal goat- the fur actually grows on the udder itself! Not MOST of the udder though. The very long fur advanced up onto the udders in the cleft that divides the two segments, tapered off almost entirely in the middle, and then increased in length again in the same cleft on the opposite side of the udder. So he is extremely shaggy on his underside, yet smooth and scaly on his upper back.
He almost foolishly asked if his transformation was done, but was interrupted immediately by a loud pop in the bridge of his nose and then the same dry grinding sound of his entire skull expanding that Eli already experienced! His nose was already shaped like a Gown Goat's, but the pressure still slept there, and now finally let loose- yanking his face outward. His upper lip became cleft, his teeth became thicker and blockier. The teeth at the front upper portion of his mouth vanished entirely and his upper jaw dipped slightly there. Only now did his iris finally change color, instead of a progressive transition like Eli. It looked like someone blasted food coloring into a spinning glass of water- from his rectangular pupils out, his brown eyes turned cyan!
It took him a minute to catch his breath. "You can... get off now."
"I already did~"
He lowered his brows. "I mean get off of ME."
"Oh, yea no. I can't."
"What do you mean you can't?!"
She lifted her hips and his hips lifted with them- her knot is too giant to get back out!
"We are tied. Till my knot goes down, we ain't going anywhere." Eli scanned the room with her bright yellow eyes, spotting her cell phone by the chair still. "Ah. We can give Lewis his form though while we wait."
She slid off the edge of the couch- she was only half-on in the first place- and onto the floor, immediately causing Sven to also fall off onto the floor, except he is on his back! She started walking across the room, dragging Sven on his back!
"S-stop tha-haaaaht-t-t. Stooop, you fucking goon!"
"Oh stop having such a pussy."
She arrived at her phone on the other side of the living room- having dragged Sven across the entire room entirely by her cock alone. Lewis had jumped onto the two-seater and had been rocking his head from one side to the other in an expression of confusion while watching them change. It certainly hasn't been the first time he seen them change, but they turn into something different every time, which also changes their scent and confuses him.
Eli activated the runic array with a nod, sitting down on Sven's lap again, resting her soft front pads on his fat titties. "For Lewis I went with Marionette Spider. I was looking for endemic monsters so his size would remain conveniently small- but hunting helpers are actually known for being portable. You can literally pick up a Marionette Spider and carry it with you after all!"
"... won't that also make him terrifying?"
She shrugged. "If you're arachnophobic, sure. As far as spiders go- Marionette Spiders are adorable."
Lewis yipped and turned around quickly, thinking something was touching his butt- but it was his tail and butt changing shape. He tried several times to turn around and catch what was touching him only to spin in circles. His normally unimpressive tail started to bulk up fast- but grew in girth faster than in length! It very quickly became so thick in fact that it consumed his anus, which slid across the increasingly bulbous structure to stop at the very end of it- a forming arthropod abdomen! Rather than his fur falling out as you might expect with an arachnid transformation- it became softer and continued to grow over the newly expanded mass, keeping it completely covered even as it grew. Marionette Spiders are entirely covered in frizzy soft fur!
Lewis unintentionally booped himself in the nose several times- still trying to see behind himself, but also still trying to wag his tail; even though it is no longer a tail at all- causing it to bop him in the face when it swings. He stopped trying to turn around when his legs started to shift though, and half-bowed his limbs to stabilize himself. He is not smart enough to understand transformation so when his limbs start to transform he thinks it's the ground moving under him, when it's his own muscles shifting.
His arms and legs started to become bulbous and freakishly muscular looking, but as they widened a divot formed down the middle and it became increasingly obvious that he was developing two more sets of limbs- dividing off the original limbs in mitosis of body parts. They did not split evenly however- as the second limb grew from the first, it robbed the first of some of its biomass, regressing its shape. A spider does not have paws after all. So as the form bloated with more muscle and bone than the limb is supposed to be able to have, the shape of the paw was lost entirely into the shuffling mass. Lewis' entire body rocked slowly with the movement of his limbs. Even the pads of his paws stretched out and the fat was re-absorbed into the rest of the body, as the dark skin tone on them faded into his normal flesh before being covered in fur too.
Suddenly Lewis' front legs started to grow, making him panic a bit because he did not know how he is supposed to be standing and its tilting him further back as it becomes more disproportionate. He staggered back a bit, but the moment he stepped back his legs finally divided- the divot forming between sections went all the way through and the now four back legs all spread apart; immediately giving him enough stability to stand properly on those limbs alone. The fur on his back legs became a diffused blue-grey, as did the turned fur on his increasingly big rump. Like with Sven before; Lewis' genitals shrank away, but he was already without balls, so it was only his sheath visibly shrinking and rather than invert into female bits, it simply phased out entirely to a blank crotch- since his transformation was not gendered.
His arms grew in size quickly, making him think he was going to be toppled over backwards by them unintentionally. They became twice the size of his four back legs and then finally split. Lewis lifted the bowed the front limbs to prevent them from toppling him over, but then discovered he could stand on the back only- so he could just lift the front limbs up off the ground and not put any weight onto them in the first place.
Under the fur, much more drastic changes were happening that were not outwardly visible at all. His bones for one are dissolving into jelly- the calcium jelly rises to the surface and stiffens his flesh into chitin, but because the Marionette Spider is covered in fur, the chitin is not hard and brittle but rather stiff and flexible- like a hard rubber. He can still feel perfectly fine through the chitin carapace- it is like tapping on a fingernail; more solid than skin, but you can still feel everything. After his spine dissolved, the nervous core swirled his organs around as it pulled taut a moment and yanked down to his underside rather than his back! Because insects are so close to the ground- it makes more sense to have their spine below them where it is least likely to be attacked. They also rely on hydraulic pressure of bodily fluids to operate their limbs- so their muscles do not tire like ours do. That is why they can often lift a disgusting amount of weight for their body size.
Then the change Sven was looking forward to the least- Lewis' entire head seemed to ripple like it had become a dense putty. His head expanded much shorter and rounder, swallowing his ears so they were merely holes before the entire skull shrank. The shape of his nose was lost entirely. His eyes folded together for a moment in a ripple during the amorphous shift, but then started to glow a diffused orange before they spread out- and as if his eyes themselves were also a liquid, spawned several smaller eyes as they drifted back apart! Two big eyes, two tiny eyes and two reeeeaaallly tiny eyes in a row across his face! The eyes looked solid orange, no whites and no pupil- if you were to look at them closely enough they are actually made up of thousands of near-microscopic pentagonal lenses; compound eyes. Because the entire eye is made up of nothing but lenses- he does not need to turn the eye to change where he is looking; he can see in every direction all of the time. The only downside is the image resolution is terrible- the world looks rather blurry to a bug. Each of a spider's sets of eyes can actually see certain colors better than others, which is why they have so many. They each give the spider a slightly different picture- and putting those pictures together in its brain gives it a better understanding of what it is looking at in spite of the low resolution.
The ripple in the head structure once again reflected off itself at the back and came back to the front- for a moment looking like his muzzle was going to reform... except it split into several sections! What had been the cheeks of his face before now spread out into two small limbs of their own! These are the palpus, and act as hands for a spider... or, if the transformation had been gendered, this is actually where his genitals would have ended up. The mandibles of his lower jaw reformed but then split entirely in two two sections- but like the rest of his body now the bone and flesh fused into chitin so there was no distinction of fang from jaw. The jaw ended in an upward hook that was formerly his lower canine teeth, and the rest of his fangs were now a serrated upper edge of the mandibles. His upper jaw broke free of the skull entirely, and gained several joints where they linked where formerly there was none. They inflated with muscle and all of his former fangs on that jaw were forced forward and fused together into two colossal fangs! These are its method of attack- these are the fangs it will ram into its prey first to drag them into its mouth. Together these four segments are known as the chelicera.
The final touch of his head shifting was the return of his ears- emerging as solid, curved triangles absolutely covered in fluffy fur. His front arms apparently were not done growing and continued to expand till they were twice the size of his secondary arms... which were already twice as big as all four of his legs. When threatened- a Marionette Spider will raise all of its arms, hiss, and wave his arms back and forth as an intimidation tactic... though due to their size, this rarely works. Through all these drastic changes; Lewis' overall mass has not changed at all, he was already exactly as big as a Marionette Spider is.
His mass certainly shifted around a lot though- his torso became smaller and smaller and as his spine essentially melted and his skin turned to chitin- his head drew back and his neck was basically phased out of existence entirely. His head could still move separately from the body so there IS a neck- but It's extremely short to the point where it's basically just a buffer of muscle between the two. His body shrank so much that his head was the same size his torso is! But his overall mass never changed- so all that missing biomass went straight to his butt. His abdomen grew massive, and took a loose teardrop shape- but unlike most spiders the 'end' of the abdomen faces almost straight up into the air by default. Marionette Spiders can lower it when they need to use the bathroom obviously- but when relaxed it faces up, not back. This allows them to launch their webbing into the air and depending on wind currents- launch their thread quite some distance from their body, allowing them to use it like a grappling hook to swing from.
The fur on most of his body was pretty short, though also dense and very soft. This fur took a diffused, pale blue- almost looking white in bright lighting. This is only interrupted on the upper abdomen (that faces forward when raised) by several arrow shaped stripes of orange that act as a caution sign to predators that the spider is irritated. The fur on the sides of its abdomen grew nearly four times as long as the rest in a strip along either side, forming a sort of crest which makes the spider look larger than it actually is. Similarly- the fur on its four front limbs is extremely long and because it is so soft and light- looks rather wispy. The underside of its abdomen, all four of its back limbs, and its head is a near-black shade of blue in contrast to the rest of its pale fur.
Lewis ran in circles again, and then just skittered around the entire room while looking at his own legs in fascination- trying to figure out what happened to him. His abdomen bobbed almost in time with his breathing- he was still trying to wag his non-existent tail.
Eli finally managed to yank her hips up off Sven- her slowly regressing knot finally popping out of the tight pussy with a loud *smeck* sound. She plod over to Lewis and pinned him down with only one paw to get him to settle down. She grinned and pet his soft fluff with the bare pads of her paw. Lewis' fur is very light and fluffy, Eli's is bushy and soft, and Sven's is dense and heavy.
While she was petting Lewis- Sven walked up behind Eli and dropped his massive tail over her- pinning her down under the weight of the canopy of fur jokingly. She grinned and turned though, booping her moist nose against the back of his udder, startling him. She gently kissed the smooth round skin to tease him but then her mind clouded by her own hormones and she could not help but latch onto one of the teats and suck again. Sven was not ready for it and the sudden pleasure drained the strength from his back legs and he almost sat on her head!
"He-e-e-ey, s-stop that! We got t-a-a-a-a-a to get ready for the convention already."
She nodded, but did not take the teat from her mouth so all she did was tug on the udder several times before finally willing herself to let go.
"We don't harrrve to be there exactly when it st-ARKs..."
"Lewis- attack!"
Sven lifted his tail and without even thinking about what he was doing; Lewis blindly followed the order and hog-tied Eli with a spool of spider silk! Marionette Spiders are not very strong and not at all threatening- but their silk is strong enough to incapacitate a monster a hundred times its body size.
Once they got cleaned up and Eli finally just used her claws to shred off the remains of her useless shirt; they set out for the convention! Thanks to the influence of the female hormones in his system; Sven was a bit intimidated by the larger forms at the convention where normally he would be completely unaffected. He also found himself blushing and thinking some dirty thoughts at the buffer men at the convention- including some formplayers, like the Rajang, or even better still... one guy came in the form of a Kirin. Though still classified as an elder 'dragon' a Kirin still has a relatively mammalian form- including external balls and sheath bobbing below it as it walks. Not to mention its lightning aura creates an area of high static electricity when you get even remotely close to it, making your hair stand on end and skin tingle.
Because of their size differences- Eli could ride on Sven's back, and Lewis could ride on her back, so there was just a three-monster stack wandering around that was still only half as tall as most of the other formplayers. Aside from a woman in a Kelbi form- no one else at the convention thought to use the form of a small monster or endemic life.
They had a bit of an advantage because of their size though; when not stacked up they can very easily go unnoticed, because everyone has their eyes on the impressive huge formplayers- especially since they could accidentally get stepped on if they don't pay attention. That means while they are still in these forms, they are all dressed up for the occasion and still get complements and people wanting to take pictures with them... but they can disappear off the radar when they want to.
Just like in Sven's futa fantasy scenarios- Eli does not know how to cope with male hormones and absentmindedly almost wandered off to follow a cute woman without even realizing- or constantly trying to nip at the huge fat teats dangling under Sven. So eventually he suggested they fuck again on the second day at the convention- going to the upper level when most of the crowd is in the main foyer on the ground floor. Thanks to tripwires set around them by Lewis they were able to make sure no one got the jump on them, and they managed a quicky right in the middle of the convention, in public. Sven's face was blushing pink the entire time, looking down at all the people on the lower level all around them while Eli crammed the too-big knot into him again, stretching his pussy around her dick like a tight rubber band while his udders swung violently below him, clapping against her balls as they swung together.
They had their fun and got away with it easily enough, though they did neglect one detail- Eli can't pull out. Her quad-knot is so huge they are tied together for over ten minutes AFTER they finish fucking. Sven was really embarrassed, having several people walk past directly by him with Eli still firmly plugging his pussy. Lewis skittered around on his back and around the floor acting as a distraction which worked for the most part. No one actually seen Eli- because Sven's tail is so gargantuan, he was able to use it to completely cloak Eli. Over thirty people walked past close enough to practically brush up against Sven, and none were aware he was tied with a horny Wulg under his goat's gown!
Though distracted thanks to their altered hormones, the two had a blast at the convention, and Lewis always has a blast, because he is always given the cutest, smallest form so he ends up being the center of attention. Even in the form of a spider, you could still tell by the way he acted that it was obviously a dog in there. Sven was glad he did not run into anyone he personally knew there- so he did not have to explain why he has huge tits that barely clear the floor. When Eli is not erect, her junk is mostly packed away so it would be real hard to tell at a glance that she has male bits- but Sven's udder is hard to miss; every step he takes makes them wobble around because they are so big they bounce off his inner thighs in order for him to walk, and the teats are so close to touching the floor that he can feel the coolness off it.
They did not even need to find a place to sit and rest like the other conventioners. Their bodies are all so fluffy that they can just rest on top of one another. Lewis is like a pillow, Eli is like a springy mattress, and Sven is like a massive heavy blanket! When they brush up against each other, the fur on fur is even more impossibly soft, and Sven often has to shrug aggressively to knock Eli off, resting her chin on him with her face buried in fur. He could tell when she started to breath deeper- she was starting to get horny off his scent again so he was quick to bat her off before she loses control again. Seeing their extravagant pelts and petting the exotic creatures- Sven and Eli are pretty sure they convinced several people at the convention at least to come next time in a small monster form themselves.
When they returned home they had yet another romp to enjoy the pleasure of the opposite gender, but were quick to undo the spells after that. As fun as the convention is, it is good to be home and in their own skin again. Although- it also did not take them long to start wondering what forms they should take in the next convention.
