Costume Crush 2 Written by Leo_Todrius Commissioned by WolfieD

There was a magic in the air - most literally. Halloween night had unveiled a dormant and hidden magic wanting to get out, to be used, to spread. Careless use by one teenager had unleashed it, and an ancient grimoire had lanced out to taint the possessions of those attending the party. Spiral notebooks had been filled with ancient spells, tablet computers had filled with an app on magic that never before existed. The netherworld wanted to spread its dark ways, and on Halloween night it had finally found its conduit.

Still, the night was growing late, and the party had unraveled with the host disappearing into the bedrooms with one of the guests. The drinks had run out, the snacks had run dry and soon the students excused themselves from the party, unaware of the strange bounty in their bags, their pockets, or their phones.

Ryan moved out of the house, his backpack slung up over his shoulders, pretty satisfied with how the night had gone. His costume had, for the most part, held up fairly well. He still appeared to be a street punk version of Robin, his red torn up sleeveless flannel shirt emblazoned with the gold and black R, his green gloves matching the green rubber mask around his eyes. His black torn up jeans sunk into the boots he'd painted green, and his normally dishwater blond hair had been made a bit darker with some product, though that was wearing down a bit as the night came to an end.

He made his way over to the trellis where he'd locked up his bike, entered the combination and pulled out the chain, putting it away before he hopped on and pushed off. The gradual slope of the yard gave him momentum to hop the curb and sail down the street, the wind blowing through his hair. He smiled a bit, wishing that his bicycle was a motorcycle, that would fit a superhero far more... but it was late and most everyone was heading to bed, so maybe the bike was best.

Ryan sailed past houses that were dark, houses that were TPed, houses with the sprinklers on. He saw some houses still partying, others decidedly unfestive, and even a few that already... ALREADY had Christmas decorations out. He smiled a bit, knowing that it took all kinds, and he was glad that his family was the kind that enjoyed Halloween immensely.

As the teenager pulled onto his street, he grinned a bit, looking to the end. Past all the houses with measly jack-o-lanterns, past the houses with a few orange and purple lights, was his house. A massive inflatable moon was sitting on the roof of the house, casting a creamy white glow across the lawn. Six jack-o-lanterns with intricate carvings of the classic monsters sat on the porch, flickering away.

Ryan peddled all the way back home and brought his bike up to the house, lifting the garage door up enough to push it inside before letting the slats rumble back down to the ground. He moved up the sidewalk for the front door and reached for it as the door knob clicked and eased open with an exaggerated creaky groan.

Standing on the other side was a wolfman that looked like he was out of the classic movies; wavy brown hair, a short bushy brown beard, a black nose, pointed ears and exaggerated features. The prosthetic work was pretty nice, and in the dim light the seams couldn't be seen at all. The man was even wearing a torn up plaid shirt and blue jeans with fake fur poking out through the gaps.

"Happy Halloween. Did you have fun?" The wolfman asked. Ryan flashed a grin as he dug a hand into the candy bowl, fishing out a half dozen fun sized pieces.

"Yeah, it was pretty cool, although the host went missing part way through. Still, great snacks and music and pizza for days." Ryan said, reaching to peel off his rubber mask, leaving the black grease paint around his eyes. The wolfman reached out and ruffled Ryan's hair, though it stuck up in spikes and cowlicks with the product in it.

"Why don't you get a shower before bed. Don't want to destroy your pillow." Ryan's dad suggested. Ryan gave a nod and set his bag down by the coffee table.

"Maybe you're right, Dad." Ryan yawned, heading back for the bathroom. His dad watched him go before he locked the front door, turned off the porch light and closed the blinds. It wasn't long before the sound of the shower could be heard in the other room. Will stretched a bit, thinking back to Halloween years gone by. He thought about Ryan growing, dressing as Sponge Bob, a pirate, a na'vi. Each year he was that much taller, that much more mature... but he still had his love of Halloween.

Will smiled with relief, glad that they hadn't gone through the stress and strain a lot of teenagers had with their parents. Maybe it was just because it was the two of them, maybe because they were in it together... but Will was glad. He moved to sit down on the couch, but something caught the corner of his eye.

With the rest of the living room dim, most of the lights turned off, there was a faint glow coming from Ryan's backpack. Will leaned over and unzipped the bag, looking inside. Sure enough, it was Ryan's tablet. He gave a soft smirk and pulled it out to turn it off, but the image on display surprised Will. The screen was filled with what looked to be a parchment background with intricate drawings of some sort of monster and strings of words.

It looked like a digitized book of some sort, although it was more than just a scan of an old book. The letters were in high resolution, clearly placed over the parchment background. It was like a program meant to look like an old book. Will swiped his finger across it, and rather than just flashing to another page, the letters swirled and spiraled away before new ones bubbled up. Will looked up, still hearing the sound of the shower. His eyes went back to the tablet.

Will wondered if it was from some D&D campaign, but the spells were broad and detailed, covering a variety of topics. Will flipped from one page to the next before he froze, seeing a large illustrated werewolf perched on a rock, howling at the moon. The image was not only detailed, it was anatomically correct. Will was staring at it when he heard the bathroom door click open.

The embarrassed father stuffed the tablet between the cushions of the couch before the door opened all the way and Ryan stepped out, dressed now only in his shorts. His hair was back to its natural dishwater blond, his face free of greasepaint. He leaned one hand on the door frame and leaned into the living room.

"Goodnight dad." Ryan said. Will blushed beneath his mask and smiled.

"Goodnight Ryan." Will said. Ryan headed down the hall to his room and shut the door. There was silence for a few moments before the gentle, steady hum of a box fan filled the room. For the first time since the bathroom door opened, Will breathed, taking in a gasp before he pulled the tablet out of the couch cushions. The 'book' or whatever it was had changed pages. Will flipped back a few before he came back to the illustration of the werewolf.

The image was floating over what appeared to be a spell of some sort. Will read it in his head a few times, though his eyes kept drifting back to the picture, the werewolf with the rather impressive member. He could feel a stirring in his pants, something that he hadn't really indulged in a while. Will leaned back on the couch, looking at it, exhaling a bit.

He had so many questions... and some of them he wasn't sure if he'd be able to ask. After all, it struck rather close to home. One of the reasons Will liked Halloween so much was that he could dress up as other things, especially... werewolves. He'd always had a liking for them, maybe too strong of a liking. Back when the internet was young, he'd been what many would consider to be a furry. Life had moved on, but the instincts, the drives, the interests remained.

For a brief moment, Will wondered if his son might have been a furry too. Was that something they shared in common? But flipping back and forth through the spell book, he couldn't find any more examples that seemed closed. Will kept returning back to the spell, reading the words. They seemed so applicable, so perfect. A small smile crossed his lips. What harm could it do? It was Halloween after all. Will reached down, running a plastic werewolf claw along the screen.

"Darkness make what I long for real, desire burn to brightest flame. Through that wish that breaks the seal, in your magic we all proclaim." Will said out loud, surprised that as he said it, the words turned red. It was a pretty sophisticated program. Still, as he finished, nothing seemed to happen. The drawing of the werewolf didn't even change.

Suddenly Will felt like an idiot, indulging in such fantasy. He shook his head and held his finger over the tablet's power button, letting the device snap off. He slid it back into his son's backpack, zipped it up and left it alone. It was such a breach of privacy, but he'd meant to just turn it off to save battery. Surely it wasn't too big of a grievance. Will got up and moved over, turning off the last few lights, turning to head to bed when he paused. There was still a warm creamy glow washing over the front lawn.

"The inflatable..." Will murmured, groaning. He walked back across the living room, unlocked the front door and moved out under the porch. One by one the candles in the jack-o-lanterns were extinguished and he stepped out onto the lawn to get the extension cord running to the inflatable moon. As he stepped out into the light, Will started to feel a little warm, a tingling spreading across his back.

He thought little of it until he reached for the cord and turned, looking up at the massive moon sitting on his roof. As the creamy white light washed over him, Will was transfixed. He gazed up at it, the light reflecting in his eyes, pouring into them as the hazel brown got brighter and brighter until it was a vivid amber in color.

Will was frozen there in the fake moonlight, feeling very real and very strange sensations. The fake fur sticking out from the holes in his jeans tingled and even stung as the hairs embedded themselves in his flesh, sinking back into the skin. Once they had taken root, new hairs began pushing out of the skin around it, growing out little by little, spreading up and down his legs.

The thirty six year old man shuddered suddenly, panting hard as his fake teeth felt oddly gummy in his mouth, feeling almost too big. The plastic veneers got hot, almost melting as they fused to his teeth, turning into real bone. His canine teeth elongated in his mouth, pushing his lips out around his growing maw.

Will reached up to claw and tear at his shirt, doing too good of a job. His fake claws had gotten longer, thicker and sharper as they fused to his fingernails, melting down over them, rooting deep into his fingers. Buttons popped and the shirt split open, revealing an unruly forest of hair as it softened and lengthened. His nipples were as hard as diamonds, but his flannel shirt was getting tighter by the second.

His ears popped and then burned, the heat dying back as the rubber over his ears became flesh, connecting and merging with him. Suddenly he could hear everything in his house... Is son falling asleep, the fan going. He could hear every cat in the neighborhood, even the neighbors sleeping. He was the only sapient creature awake for at least four houses.

Will panted, his heart racing, groaning as his mind started to process the sensations. It had been so many years since he had fantasized about this, but it was just like he imagined it to be... His senses were coming to life, his body was waking up and becoming something better, he- The next thought burned out of his mind as his face ached and throbbed and tingled, the wolfman prosthetic he had made connecting to him, becoming part of him. His nostrils flared as they pushed forward into a short muzzle, his nose becoming black and moist as the paint sank in to the flesh, becoming real.

The revelation and reverie of the change came to an abrupt end as Will felt a tightness growing around his chest. The flannel shirt he had been wearing was getting tighter and tighter, or rather he was getting bigger. A button popped, then a second, a narrow window opening up to show off the hair on his chest - hair that was getting softer, thicker, longer. It was a salt and pepper mix, lighter than the hair on his head... or his face.

Will had usually kept a beard since he was Ryan's age, thick but well groomed around the jaw line, a little thinner on the mustache than he would have hoped for. When he'd been putting on the prosthetics, he'd blended his natural hair with a bit of synthetic hair to try and match up the cheeks better. It had looked okay, though he felt soft stinging pokes as the hair from his mask dropped down into his skin, taking root as the magic turned them from fake into real hairs. They filled in his cheeks all the way up to just below his eye line, becoming soft and wavy.

Hot, moist breaths passed in and out over the fangs in Will's mouth, becoming hotter by the second. As the air moved in to his lungs, his shirt split open all the way down, revealing a furry chest and a hairy stomach that was getting furrier by the second. His pecs were huge and his nipples were growing wider, thicker and longer. He snarled softly, his ears stretching high into points.

He growled softly with a deep, reverberating bass that filled his chest as his face throbbed and burned in a strangely delightful way. His well groomed beard started to stretch. At first it was in patches, longer in the cheeks, then the chin, but soon it was growing all over. Centimeter by centimeter, it extruded out of his face. Even the mustache he never had been able to cultivate was thickening, getting bushier, growing down over his upper lip until it disappeared from view.

The beard grew out and down and to the sides, inch after inch. It hit his adam's apple, the base of his neck, then his collarbone. He'd gone from a dad to a daddy in moments. It was thick, luxurious, immense, like a mane more than a beard. Will threw his head back and let out a moan, a moan that grew into a soft, subtle howl. As he did, his mouth pushed out more around his sharp teeth, taking on a more distinct muzzle shape.

A deep, dull but growing sense of power was welling up in the man. It was a deep seeded power, a heat, a drive, an instinct... He had done what any good parent did, and tried the best he could as each situation came, learning from past experiences. It had never gotten easier, there had always been an uncertainty, a feeling that it was improvised. He was in his mid thirties, and he had still felt like he was figuring it out... but somewhere deep down, that was changing.

He was an alpha, a beast, a creature of the night. That power got stronger, creeping down his chest, through his stomach before settling in his groin. Will shuddered as he felt the heat, the throbbing, the pulsing creep that far down. His clawed hand dropped, fumbling with the button to his pants, then the fly, whipping out his manhood. It was already hard, so hard, but it was getting harder.

Will started to stroke himself off in the glow of the fake moon, letting it wash over him. The skin on his cock moved liberally, slipping up and down as it stretched, sliding up over the cock head in ways it never had before. Blood was flowing into the cock as it stretched longer than ever before, but still there was a lot of give to the skin... until the reason became clear. While the cock beneath was getting redder and redder, the outer flesh was starting to get fuzzy. Soft downy clear hairs emerged, creeping up the base as the skin got tougher and more leathery... until in one slick move, it pulled free, turning into a sheathe.

A hiss escaped Will's wolfy lips as his sheath pulled back, revealing his massive red cock. He pushed the sheathe back out of the way and grabbed on to his real rod, feeling it swell and tighten. With each thrust of his hand, the tip pushed more into a point, leaving the human mushroom shape behind. It took on a slight, faint curve and the base began to plump on either side. Will growled, his cock pushing past twelve inches, then fourteen, then sixteen.

His abused pants began to sag, revealing his balls - balls that had been covered with the same salt and pepper fur that covered his chest and stomach. It also revealed his muscled, meaty, thick furry ass cheeks - cheeks that slowly pushed apart from one another to reveal his plump, thick hole. It was a black ring surrounded by brown fur, and one quivering nub that was wriggling as it began to change.

It had been a subtle change at first, but slowly new bones formed, pushing each other apart, forming one after another as ligament and muscle wrapped around it all beneath the skin. The nub was his tailbone, and soon it was just that. Inch after inch stretched out as the fur got thicker and bushier, growing out as his tail dropped down behind him. It stretched down to his knees, his ankles, and then finally brushed the ground.

Will's ears popped again as they pushed out from his head, fur covering the entire backside as they went full wolf. He flicked his tail, wriggled his huge shoulders, and then groaned as his feet started to ache and throb. The cartilage popped as his feet spread out across the grass, his toenails darkening and curving, growing out into claws. The soles of his feet got puffy, developing into paw pads as his feet got big enough to support his increased weight and size.

Small changes finalized, sweeping over Will from head to toe. His hair was bushy, his beard huge, his face a combination of man and animal. His chest was broad, his cock long, his tail thick... He had become something else, something more. The magic had blended his Halloween costume and himself, creating something new... but it wasn't without consequences. The wolfman grunted, his head swimming with confusion, with heat, with lust, with the desire for dark magic to spread... for his kind to spread... He lifted his head, hearing the sound of the box fan in his son's room, a grin crossing his muzzle.

****

Even with the cool weather of Fall, Ryan's box fan brought him a deep restful slumber. He was a bit of a furnace when he slept and it kept him cool, but it also made it easier to breathe, bringing in lungs full of air with ease. Ryan was deep asleep, breathing in and out, but even in an unconscious state he could sense the air was changing... It was getting a little warmer, a little muskier, spicy, earthy, peaty. He shifted a little, his nipples tightening and his cock getting a little harder in his sleep.

Will stood on the other side of the fan, wearing only his torn, split open plaid flannel shirt. His tail wagged behind him, his huge feet dug into the carpet, his clawed hand slipped up and down his huge cock. He looked down at Ryan, his son, his pup, his legacy. He licked his lips slowly. It wasn't right that he was still human, still weak. He had to help his boy.

"Ryan..." Will said, moving closer to the bed. Ryan murmured but did not wake up. Will moved closer again, "Ryan, wake up..." Will growled. The blond teenager murmured again, eyes opening. They were blurry at first, but as they opened to see a cock, his blue eyes snapped open wider. He rose up in confusion, looking up, surprise and fear mixing together as he looked at a furry stomach, a furry chest, a huge beard and... and... his father's eyes?

"D-Dad?" Ryan asked, the cool air from the fan blasting across his bare chest. Will grinned, taking the hand from his cock to caress his son's cheek, though it was a bit moist from pre. The musky smell swam around Ryan's head, making him feel dizzy and his cock get even harder, standing right up in his boxers.

"Ryan... I've awoken as my true self... and it's time for you to wake up too. We're a family, you are my son, you are my pup... and I want to give this gift to you." Will growled. Ryan murmured, feeling almost impossibly horny but still confused.

"Dad, how? H-how did... this happen?" Ryan asked. Will grinned a little.

"I found the spell book in your tablet... I'm sorry for reading it without your permission, but look at this gift that it gave us..." Will grinned.

"Spell... book?" Ryan asked. Will growled.

"It doesn't matter Ryan... All that matters is us. You are a man now, but I want to make you more than that... Drink from me, my pup, let the beast in you come out. Be like me, be with me... and we will start a pack of our own." Will said. Ryan looked up at his father, confused from the pre, turned on by the musk, and feeling strange... strange feelings.

Ryan loved his dad, his dad had always sacrificed and worked hard to take care of him. They never fought, they shared good experiences, and here he was, reaching out, looking... oddly... amazing. He was huge, strong, ripped, shredded, manly as fuck... That beard alone. Ryan bit his bottom lip, looking up at his dad, panting softly as his own cock started to leak clear pre.

"I love you dad..." he said softly. Will grinned.

"And I love you son." Will said proudly. Ryan leaned forward of his own volition, opening his mouth. His tongue slipped out and he gently licked his father's cock. The pre was like an explosion of flavor on his tongue, smelling of sex and power and nature. Ryan's eyes fluttered shut and he slipped his lips around the head, starting to suck and slurp.

Will threw his head back, letting out a growl as spurts of pre splashed out of his cock. Ryan gulped at them, letting them coat his teeth and tongue and throat, spilling down to his stomach. He slipped down another inch, then another, letting his dad's wolf cock fill his mouth, bumping the back of his throat. As Ryan started to bob his head back and forth, Will started to thrust in and out, picking up speed, growling happily.

The changes that happened first were subtle. The roots of Ryan's blond hair started to darken from blond to brown until they matched the same shade as his father's hair. It crept out little by little until his blond locks were fully brown, his eyebrows coming to match. Several genes from his mother had been altered, bringing Ryan more in line with his father, making him truly his dad's son.

Ryan moaned around the wolf cock, sending vibrations down the length, sucking and slurping. Peach fuzz started growing out across his upper lip and his chin, the clear hairs getting longer and thicker and softer until brown pigment swept into them. In moments Ryan had his first mustache and a little bit of a goatee... a goatee that was getting longer, stretching down to half an inch, then an inch, then two.

The eighteen year old's mustache got thicker and longer, curving down the sides of his mouth. His cheeks got fuzzy next, sideburns sprouting out, getting thicker, creeping down inch by inch until it hit his jawbone. Ryan's newly brown hair was getting longer too, going from well groomed to shaggy, dropping down across his forehead, over his ears, down the nape of his neck.

Will looked down at his son, his true son. Of course his boy would have a beard, just like him... hairy and fuzzy all over, and he'd never get rid of that beard. It would just get bigger and bigger with every year until he had a mane like his daddy. Will growled happily at that and shuddered as his pre became something else. The clear fluid got thicker, coming in globs, turning to pearl and then yellow. Ryan's slurping became more desperate as he tasted his father's cum and the dark magic really started taking root in the boy.

A patch of fur sprouted from Ryan's chest, then his pits. Arm hair became thicker and softer, leg hair sprouted. One plump ball slipped out of the leg of Ryan's boxers as new hairs grew across it, the sack getting thicker and heavier and fuller by the second. Ryan bobbed his head faster and faster, sucking his dad off, filling his belly with cum. Will growled, then howled, grabbing his son's head with his clawed hand, pulling him closer.

The wolf cock hit the back of Ryan's throat, then the boy tilted his head, letting the cock slide down the throat almost all the way to his stomach. His face was mashed into his father's furry bush as he gulped and drained the cum his Alpha had to offer. As he was held there, his pecs tightened, his abs hardened, his biceps and triceps grew. Just from drinking down his dad's jism, he was growing heavier, thicker, tougher.

Ryan's fit, fine body was now a powerhouse, like a wrestler... but more than that. Fur sprouted out across his bare shoulders, his back, coming in patches that spread out until they connected and thickened. The fly on Ryan's pants parted and a smaller but distinctly wolf cock began poking out, the red pepper shaped tip emerging, dripping with pre as the base fattened and lengthened, his sheathe forming at the base.

Will growled and came harder and harder, giving his son more cum to work with as he looked down. The shaggy hair had hidden the fact that Ryan's ears had been reabsorbed into his head, deafening the boy for a few moments before new, fuzzy points pushed up from the top of his head, emerging from the hair. Wolf ears stretched up, twitching, fully functional as new channels formed inside his skull.

Ryan murmured happily, feeling warm and fuzzy all over. The fur closed across his torso, his legs, his balls. His toenails caught in the blanket, snagging as his toenails grew out, darkening and sharpening into claws. Will tried to pull back to thrust into that throat sleeve, but Ryan stubbornly held on.

The tug of war coming from it began to stretch out Ryan's face. Each pull made his jaw and nose push forward, making room for his teeth to swell and sharpen into fangs. His nose distended, the nostrils flaring and tilting up, the flesh getting dark and moist. Will growled and tugged back, his cock accidentally popping free from his son's mouth, giving his face a thick sticky spray of yellow wolf cum.

Ryan licked up the cum as best he could with an abnormally long tongue, but the cum hung on his mustache and goatee as his sideburns crept forward, new hair emerging, pushing out on his cheeks until the beard covered his face - just like his daddy. The wolf pup let out a demanding growl of his own and lunged forward, wrapping his mouth and throat around his father's cock once more, his clawed hands grabbing onto Will's waist to anchor.

As he moved, Ryan's ass hiked up in the air, revealing his growing tail nub. He sucked and slurped, guzzling his dad's cum down, filling his stomach with it until it felt close to bursting, but still he wanted more. Will watched with pride as his son's changes cemented themselves, linking together and intensifying.

Will couldn't have felt prouder. His pup, his boy was a true wolf just like him. His wolf cock and balls were big, his tail was right there, his muscles were immense. He was strong and fit and dedicated... and such a good lover. Will moaned, throwing his head back, letting out a howl that grew in intensity until the windows, and even the fake moon tacked onto the roof, shook. Hearing his dad howl, Ryan slipped over the edge into orgasm as his newly changed wolf cock unleashed his own seed. Every last drop of human cum was expelled, leaving only the yellow spooge of a true werewolf.

The tempo of their love making began to slow. Their breathing softened, their heart rates decreased. Will was spent, sweaty, happy and content. Ryan still had energy, but it had been depleted for the most part by his growth spurt. Will pulled back, his cock pulling free of his son's bearded, muzzled mouth. A long sticky string of cum connected the two for a moment until it broke.

"Come, son, you sleep in your father's bed now." Will said, turning. Ryan hopped out of bed, trotting after his father, heading into the main bedroom. The door eased shut as the two climbed into the mattress, curling up against one another, furry body to furry body. The two cuddled, falling asleep, the wash of creamy white light flooding the backyard through the window.

In the quiet house, silent save for one neglected box fan, a small chime sounded - coming from Ryan's backpack. The tablet turned itself back on for just a moment, the grimoire app's icon changing to a full moon on the menu screen before it turned itself off again. The ancient magic, used irresponsibly only once, had claimed two more souls. It was taking root again in the mortal world, and there was nothing that was going to stop it this time.
