The forest was dark, only light coming from the house they had just left behind and the full moon peeking through the trees. Harry rubbed at his arms, regretting not bringing a jacket. He glanced at Draco, his boyfriend cosy in a thick plaid shirt and a leather jacket.
“It’s gotten really cold,” he said, pulling the short cape tighter around his shoulders. At least it was made of wool, giving him some warmth in the cold October night. It was damp too, thick fog curling over the path they were walking down.
“You’re the one who wanted to be Little Red Riding Hood,” Draco said. Harry sighed, trying to tug his skirt down lower; it wouldn’t reach far below his bum, regardless of what he did. His socks only came up to above his knees and Draco had convinced him to wear panties, to complete the look. The thin material left him almost bare to the wind.
“I should have been the Wolf,” he sighed.
The Halloween party had been very fun, but Harry felt completely overstimulated after the drinking and music and dancing. He hadn’t worn a skirt outside of his own flat before, so jumping straight into the deep end with this short a skirt in public had probably been a bad idea. Draco liked it, though, hands always lingering low on his back when they had been dancing or standing, and high on his thighs when they sat down, which had helped Harry’s comfort.
“If you’d been the Wolf, you wouldn’t have gotten as much attention,” Draco said with a sharp smile and a lean towards him, and Harry rolled his eyes and pushed him away. It made him stumble to the side, almost falling off the path before he caught himself. He was still grinning when he rejoined Harry.
“You’re not very good at being the Wolf, Draco. He’s supposed to be a predator, if you’d forgotten, not letting Red push him around,” Harry said, stopping to lean against a tree and fix his shoe. His boots were red with a one inch heel, giving him that classic click when he walked on wooden floors. Draco snorted, stopping in front of him with his arms crossed. Then he frowned, dropping his hands and cautiously looking around.
The air was thick with fog around them, and when Harry looked down the path he could barely see the house anymore. A different kind of cold had crept in, and he straightened up. It felt like something was close, like it was circling them, and he spun around trying to find it, or them.
“Is there something—” Draco started, and then cut himself off with a groan. Harry turned to him, found him kneeling with his arms around his stomach and his head hung low, and he crouched down next to him. Worry pooled in his stomach.
“Is it your stomach again?” he asked, recalling the anxiety cramps Draco sometimes got, but he shook his head. Draco tried to say something but it only came out as a groan, and his body heaved like he was going to vomit. He didn’t, instead gasping and spitting on the ground.
The presence was getting closer to them, like another fog creeping in, and Harry felt his heart pound. Draco groaned again, and when he looked up at Harry his eyes were wide and glassy.
“Harry...” he panted. He dropped his head with a groan that was almost animalistic, and then he looked up at him again.
His eyes were glowing silver. Harry paled in shock.
“What the fuck?” he whispered, and Draco growled. He pushed Harry away from him and Harry scrambled to stand, pulling his wand from his boot in the process. He hesitated to cast a spell, he didn’t want to hurt him. Draco growled louder, slamming his hands on the ground and revealing how his fingers and nails were extending, growing. He stared up at him with gritted teeth, suddenly much sharper, and hissed;
“Run.”
Harry’s feet worked faster than his brain, turning and sprinting down the path before he could think. He felt blind for a moment, unprepared, unsure, but his body knew what was behind him now, and what was in front of him. He ran as fast as he could towards the house, feeling hope rise when he saw the brightly lit windows get closer.
A tree was his downfall, literally. His foot caught in a raised root and he fell face first into the ground, catching himself on an elbow and feeling the sting go up his nerves. Somehow he didn’t drop his wand. He spit out pine needles and stood up, but it was already too late.
A tall, dark shape stood in front of him on two legs, towering over him with razor sharp claws and a maw open in a low growl. Harry stood up but he felt stuck to the forest floor, knees trembling. He couldn’t hurt him. That was Draco, he couldn’t.
Draco stepped closer, showing all his teeth in a wide grin, and he silently lowered himself onto all fours.
“Run,” he growled, sending icy shivers down Harry’s spine. He took a quick step back but twisted his ankle, yelping as he fell again. Draco crept closer, huge paws silent on a mat of pine needles, but then stilled.
Harry’s legs were splayed open, skirt riding up to his hips, and he felt the cold air against his crotch. He grabbed the skirt and pulled it down, breath coming in short pants as he stared at Draco’s powerful frame and the teeth that could tear him to shreds. He only barely noticed how his wrist pressed weirdly against his genitals, all of his brain power focused on staying alive.
Draco was staring at him like he was prey, and Harry crawled backwards before turning over on all fours and trying to stand up. Trying being the key word, because Draco wrapped long fingers around his ankle and kept him down. Harry choked on a scream, kicking at him to no avail.
“Sweet,” Draco murmured, in more of a purr than a growl, and then something happened that Harry did not expect.
Draco stuck his snout under his skirt and sniffed him, nose pressed to his damp crotch and breathing deep.
It was then that Harry realised something had changed down there, and when Draco hooked his sharp claws through the fabric of the panties and shredded it until it fell off his body, he gasped. That was a cunt between his legs, now dripping down his inner thighs with arousal. In the back of his mind, where he could still reason, he reasonably assumed that whatever magic had turned Draco into a werewolf had probably done this to him too. The rest of his mind was still in alert, panicked mode.
He tried to tug his leg away again and succeeded, Draco letting him get up and back away from him. He was watching him still, but there was something in his eyes that made Harry not turn on his heel and run away.
He pressed a hand to his chest, feeling his heart pounding against his ribs. If he ran, Draco would run too. But if he stayed, Draco wouldn’t hurt him. He didn’t look like he wanted to eat Harry... except maybe in a sexual sense, going by how he was licking his lips and staring at Harry’s crotch. That was surprisingly exciting to think about.
“Don’t hurt me,” he said quietly, testing the waters. Sweat was pooling on his skin and chilling him, and he pulled the cape a little tighter around him. Draco leaned his head to the side.
“I won’t,” he said, and now that he wasn’t so afraid Harry could recognise his voice better, even deep and roughened as it was. Draco crept closer. Even on all fours he was eye level with Harry, and it sent instinctive terror down his spine. “You smell so sweet,” he added, lowering his head to scent. Harry pulled at the skirt in embarrassment.
“Why did you tell me to run then?” he asked, ignoring Draco’s latter statement. Draco leaned his head to the side and curled into himself, like he was making himself smaller.
“I didn’t feel in control of myself,” he said. Harry could see his body better, saw the sleek dark grey fur and the lean muscularity of his torso and legs. His tail was long and shaggy. Harry thought about petting him, and then immediately waved the thought away.
“And the second time?” Harry asked, ignoring how his pussy clenched around nothing when Draco’s growled ’run’ echoed in his head. Draco smiled again, and he carefully padded closer. Harry stood as still as possible, tried to breathe evenly, as Draco circled him tightly, tail brushing against his legs and back. Fuck, he was so big, palms so wide he could easily hold both of Harry’s ankles in one hand.
“It made your scent thicker,” Draco said, and dipped his head down to rub his nose against Harry’s leg. He yelped, but there wasn’t much space to move away when Draco was all around him. “I know what you want,” he added, and Harry swallowed. His mouth was dry.
“You think you do,” he said, stubbornly defiant. Draco would not let him live it down if he just threw himself at him. Fuck, they were still close to the house, anyone could be walking in their direction.
“I can smell your wetness,” Draco purred, and before Harry could stop him he’d pressed his snout between his legs and licked. Tightening his legs did nothing, Draco’s long tongue sliding against his folds regardless. Harry held back a moan, staring intently in the direction of the house to see if anyone was close.
“Someone’s coming!” he hissed, spotting someone short walking down the path. He tried to push Draco towards the trees, so he could run away and hide, but Draco had other plans. He stood up suddenly, scented the air, and then wrapped his arm around Harry’s waist to pick him up. Only barely did Harry hold back a sound of surprise, not wanting to alert whoever it was. Draco walked fast, disappearing behind the trees before they could be spotted, and Harry clung to him with his arms and legs. It was only when he was put down in a small clearing that he realised he’d dampened Draco’s fur where his crotch had been pressed. His ears felt hot, internally begging that Draco wouldn’t notice, but of course he did. He bent his neck until he could sniff the wet spot, and then grinned at Harry.
“I do know what you want,” he said, and Harry crossed his arms over his stomach.
“We’re less than two hundred metres from the house,” he said, ignoring how that fact made his stomach clench. “We’ll be caught immediately and they’ll try to ‘rescue’—” he made exaggerated quotation marks in the air, “—me from you.” Draco dropped to all fours again, grazing his nose over Harry’s chest and stomach. It made him shudder reflexively, being that close to his maw.
“I can take you deeper into the woods,” he said, sitting back on his haunches to run his hands over Harry’s arms. He was very warm. “I can take you somewhere no one will hear you scream.” Harry swallowed back a gasp, but it was useless. Without underwear, even those thin panties that Draco had convinced him to wear, he was dripping down his thighs. He felt almost dizzy with arousal, a sensation so familiar yet so foreign at the same time.
“Where are your clothes?” he asked, trying to stall so he could regain his composure. “Did you rip them all when you transformed?” Draco shook his head, which looked strange for a werewolf.
“I managed to take them off before I fully turned.” He caressed Harry’s cheek, claws resting gently on his hair. “They’re near the house, you don’t need to worry.” Harry sighed quietly and leaned into his hand, and then stepped closer, between his legs, to hug him. His chest was huge in this state, too wide for Harry to wrap around, and he was emitting body heat like a furnace. He didn’t smell half bad either, a pleasant and light musk. Harry hummed when Draco carefully enveloped him too.
“Okay.” Harry stepped back to look him in the eyes. “Kidnap me then, Big Bad Wolf,” he continued with a teasing smile, and Draco grinned at him.
“My,” he murmured and gripped Harry’s hips, “what is that scent?” Then he hefted Harry into the air, pulling a choked back scream from him, and held him aloft with his legs spread. His skirt had flipped up again and it was easy for Draco to drag his tongue up Harry’s cunt, sending an electric shock through Harry’s stomach. It felt amazing, held in in midair with a wide tongue licking him, firm over his entrance and the tiny nub above it. He held onto Draco’s hands when he was lowered down, so he wouldn’t fall over with his knees shaking. After letting go of him Draco got on all fours and laid down, and Harry stared at him before taking the implied invitation and climbing on. He dug his legs into his sides and his hands into his thick fur, and he was happy for it once Draco stood up and started running.
He was so strong, easily carrying Harry as he darted between trees and jumped over bushes. Their surroundings rushed past them so Harry buried his face against his neck, clinging on until Draco slowed down. When he looked up they were in front of a cliff, maybe ten metres tall, by an outcropping that formed a shallow cave. Draco laid down and let Harry slide off, laughing a rumbling laugh when Harry fell to his knees immediately. He reached back and touched the wet spot in his fur, smiling when Harry flipped him off. Draco helped him up and brought him into the cave, which was a few metres deep. It was more than enough for Harry, whose entire body felt electrified and hot, and as soon as Draco crouched down he wrapped his arms around his neck.
“Please,” he whispered, ignoring Draco’s amused huff. His unspoken wish was granted when Draco directed him to bend over against the wall, legs wide. The air was cold against his dripping wet cunt for just a moment before Draco laved his tongue over it, warm breath puffing against his skin. His hands wrapped around his thighs easily, holding him open while he licked, and Harry was glad for the steadying grip. Otherwise he would have fallen right down on the ground. It probably wouldn’t have been bad, though, if Draco continued licking him out.
It was an obscene noise coming from him, every rumble and groan overpowered by how wet Harry was. He was gushing onto Draco’s tongue, moaning loudly when his clit was stimulated. He’d known intellectually how sensitive the clitoris was but actually feeling that heat run up his nerves and his cunt tingle made his brain melt.
“That feels so fucking good,” Harry mumbled, looking behind himself at Draco. His eyes were closed, muzzle wet with Harry’s fluids, but he opened them to look at him. He pulled back and panted, tongue lolling out between his teeth, and Harry twisted to reach back and pat him between the ears. His fur was silky. Draco pressed into his hand with a low grunt. He flicked his tongue against Harry’s bum cheek and then rested his his chin on it.
“I wish I could finger you,” he sighed, flexing his claws against Harry’s thighs. Harry bit his lip, running his fingers along Draco’s soft lips. He felt his teeth under them, and Draco smiled a little, making his stomach jump.
“I think you can use your tongue,” he said, and Draco’s eyes widened. He sat up from his crouched position and ran his hands up Harry’s thighs before gripping his hips. He crept closer and draped himself over him, and Harry gasped when he felt the thick shaft push in between his legs. He looked down, grabbing his skirt to pull it out of the way, and stared at the twitching red tip.
“You’ll need it,” Draco said, reaching around to press his palm flat over his cock, showing how it would almost reach his belly button.
”That won’t fit,” he said, slowly shaking his head. It would burst through him, he’d break. Draco rumbled a laugh, noise vibrating through Harry’s chest, and pulled back to crouch again.
“I’ll make it,” he said, and before Harry could protest that he pressed his tongue into him. It was thick and flexible, so hot it almost burned, wiggling its way up his pussy. Harry almost screamed, clenching his fists against the rough cave wall. His knees would have given out if Draco wasn’t holding him up with his strong hands, weak with unbearable pleasure.
“Draco!” He tried to push down on his tongue but couldn’t move his hips farther than an inch. Draco was ruthless, thrusting his tongue in and out, fast and deep. His teeth grazed Harry’s lips, against soft plush skin, and it lit up his nerves. He felt hot all over, sweat slipping down his spine and arms and thighs, but his stomach went cold when Draco growled. It was so close to this most vulnerable part of himself, teeth one sharp snap away from digging into his guts. He shuddered, head swimming. He couldn’t understand why the fear made him wetter, why it made his knees weak. It made him want to lay back for Draco and let him do anything.
Harry dug his fingers into the wall when he came, stomach squeezing, and his trembling voice echoed in the cave. His cunt spasmed around Draco’s tongue and his thighs were hot, wet. It took a moment for him to realise he was squirting, and when he looked down he saw the puddle growing under him and his white socks soaking up the fluid. Draco didn’t stop eating him out and Harry slid down, bending in half but scrambling to hold himself upright. His eyes rolled back in his head and he screamed again, and Draco finally stopped moving after it faded into whimpers. He pulled his tongue out and gently lifted Harry up, sitting up so he could cradle him in his lap.
“You’re soaked,” Harry said, running his limp hand over Draco’s damp chest. Draco licked his lips and squeezed him closer, and Harry sighed. He wrapped his arm around his thick neck and pulled himself up, so he could kiss Draco on the cheek. Draco flicked his tongue against Harry’s chin and then bumped his nose against his cheek.
“I think I’ll fit now,” he said, carefully trailing a finger over Harry’s pussy. His body trembled at the light touch, and Harry fisted his hands in his fur.
Draco was too tall for Harry to stand bent against a wall and being on all fours hurt his hands and knees. Instead Draco crouched down and held him against his chest, Harry wrapping his legs around his waist as well as he could.
“Can I put it in?” Draco asked, hands tight over Harry’s hips. Harry nodded, reaching down to help guide the tapered head into his pussy. It was easy to the take the first few inches but it quickly widened to a point it hurt. Draco noticed his discomfort and pulled him up, and then lowered him down again. When it stretched him for just a moment before giving him reprieve it felt good, and Harry’s tense insides slowly relaxed. He pressed his face to Draco’s chest, fur thick and soft against his skin. He rubbed his hands over his collarbones and up his shoulders, feeling his muscles play as he lowered and raised Harry on his cock.
“Shit,” he hissed, toes curling in his boots. Draco didn’t move his hips, staying still while Harry was moved up and down like a toy. His legs slipped from Draco’s waist and he had to tighten them around him, even though it was hard to focus on anything but the thick cock slowly making its way deeper into him. “Shit, Draco.” Draco groaned loudly, dipping his head down and nosing Harry’s hair.
“So tight and wet,” he muttered, hands squeezing tighter for a moment. Harry let out a long, keening moan when Draco pushed him down a little rougher, a little faster. “Does it feel good?” He asked and Harry nodded fervently, eyes rolling back in his head. Draco was deep inside, the widest part of his cock having stretched it way past his entrance, and Harry blindly reached down to feel the rest of him. His fingers grazed the bulbous swell of the base and his breath hitched.
“That’s going inside me,” he said, determined and aroused out of his mind. Draco growled quietly. He thrusted, and Harry saw stars. The pointed head stimulated him so perfectly, jabbing against something so sensitive it was almost painful. Draco did it again, and a cacophony of noise left Harry, interspersed with choked swears. He’d never even imagined anything close to this and he couldn’t believe how good it felt.
“You’re taking it so well,” Draco said in an awed tone, and Harry looked down, seeing the bulging in his stomach through the shirt.
“I’m full,” he mumbled, slipping a hand down to rub over his abdomen, heart jumping when Draco loudly growled.
Harry was suddenly horizontal in the air, Draco leant forward on his hand. He slipped out so quickly it made a loud squelching noise, and Harry shook his disoriented head. He felt the tip of Draco’s cock slide into his cunt again and without warning, he started thrusting fast into Harry. It was relentless, battering his cunt without mercy and making his body seize up as he orgasmed again, but Draco didn’t stop this time. He kept going, through Harry’s climax, balls slapping against his bum and his claws digging into his back. It was terrifying, painful, completely humiliating— and Harry loved every second. His hands scrambled to find purchase in Draco’s fur, legs spreading around his hips, crying out whenever his tip jammed against that spot inside him. Draco was growling loudly, the noise echoing against the cave walls, and Harry felt like a beast, any human thinking completely sinking down to give way to the animalistic instincts of fucking and fear.
Harry had come once more when Draco changed his pace, not pulling out as far before slamming back in, grinding deep inside him. He pressed his snout to Harry’s ear, still snarling.
“Now you’ll be full,” he said, and before Harry could try to make sense of that statement Draco pushed the thick base into Harry’s pussy and held him tight. For a moment he wasn’t sure what was happening but then he felt the stretch, the unnatural heat spreading inside him, and Harry’s eyes rolled back in his head. He wanted to reach down and touch himself but his arms were like jelly, and he jumped when he felt Draco snake his hand in between their torso and rub a rough finger pad over his clit. The fast and concentrated stimulation quickly brought him over the edge and as Harry screamed his orgasm, his voice cracked. Draco mercifully pulled his hand away and instead wrapped both arms around him, holding him close while he laid down on his side. Harry wanted to say something, but the exhaustion stole his words, and he curled into Draco’s chest, hoping the shaking would stop soon.
Draco kept making a low rumbling sound in his chest, like the precursor to a growl, and Harry felt soothed by it. He was almost purring, and Harry found himself petting Draco’s thick fur.
“You are the Big Bad Wolf,” Harry said, voice strained and rough. Draco laughed, licking his forehead gently before sighing.
“I don’t remember the fairytale ending like this,” he said, making Harry snort.
“It’s the new version for adults,” he said. Draco had laid down with his back to the exit of the cave, protecting Harry from the cold. “You’re so warm, like a furnace,” he added and buried his face in his chest. He had to move carefully or Draco’s cock would shift against something inside him and make his limbs weak.
“I wonder if they’re looking for us,” Draco asked with a yawn. “I don’t think they could have heard it was you screaming, if they even heard it.” Harry sighed and shrugged.
“Who cares. Your cock is amazing,” he said, and Draco laughed again.
“You’ll never want to have sex with me after we break this spell,” he said, making Harry’s cheeks heat.
“If I screamed until my voice broke and almost passed out every time we had sex, I wouldn’t want to have sex with you." He slid his hand down to his stomach, finding that Draco’s breath hitched if he stroked the bulge. “This isn’t the worst, though.”
After a long time, longer than Harry could keep track of, he felt Draco’s cock twitch a little and then a torrent of liquid gushed out of him. It soaked into his clothes and Draco’s fur, the musky scent rising around them.
“Gross,” Draco muttered, sitting up and carefully helping Harry into his lap. His body was completely boneless, limbs like jello, and Harry sighed.
“I won’t be able to walk back,” he said. “Or Apparate,” he added, and Draco hummed. Standing up, he hefted Harry up to rest against his chest, holding him up with just one hand. Harry blushed when he felt his pussy try to squeeze around nothing, and he buried his face in Draco’s chest. Draco made sure he was held securely and then stepped out of the cave.
Harry felt in between asleep and awake as Draco walked, mostly hearing his steps on heavy soil and the wind rustling in the leaves. From his head to his toes, his body ached, all of it concentrating in the bottom of his stomach. His clothes were wet and probably ripped, and he dimly wondered how they were getting home, if Draco didn’t become human again.
When he finally looked up he recognised their surroundings, walking a few metres from the path to and from the house. He looked up at Draco, his eyes set in a focused frown, face framed by the full moon. Noticing Harry looking at him, Draco paused to graze his nose over his cheek.
“I put my clothes near here,” he said, and they only had to walk for maybe a minute before they reached the spot. Draco set Harry down on his feet but didn’t let go, which Harry was grateful for. The bonelessness was mostly gone but had been replaced with a tremor, and he slowly sunk down to his knees. His clothes were so dirty, but he didn’t even care at this point. Draco took his clothes out of a bush, his wand tucked into them. He frowned, setting them down on a fallen tree and then sitting down in a crouch. For a moment everything was still, and then Draco’s ears perked up and he stared wide eyed around them.
That fog was creeping in again, that cold and slippery feeling surrounding them, and Harry held his breath for a moment. Around them the forest stilled, and then something snapped, sounding like a tree branch. Draco whimpered, falling to his hands and knees, and Harry watched with horror-tinged curiosity as the fur shedded from him, falling off in droves as he shrank and contorted and bent. It was over in less than a minute, seeming less painful than the first transformation, and it left Draco naked and sweaty in a pile of fur. Something squeezed in Harry, and he stuck his hand between his legs just in time to feel his cock and balls appear from his crotch.
“This is the weirdest Halloween I’ve ever had,” he declared, and Draco didn’t protest.
They cleaned up and Draco got dressed, and then Harry stood leant against a tree while Draco transfigured his cape until it covered more skin. Where it previously reached his hips it now brushed his ankles, and he gratefully swept it around his body. Slowly they walked back to the path and continued where they had been interrupted, walking out of the forest to the Muggle bus stop. Draco ended up giving Harry his arm so he could steady himself on it, and Harry squeezed it in a hug.
The bus stop was tucked in between several pines, a mat of pine needles covering the ground. Harry sat down carefully, since there was still a strange soreness in his core.
“What could have done that?” Draco asked, sitting down with an arm around Harry’s shoulders. Harry sighed, yawning and shrugging his shoulders. His eyelids were drooping. “I’ve never heard of magic that could temporarily change someone’s body in such a drastic way.”
“Maybe it’s the Halloween spirit,” Harry mumbled. “I read about trick or treaters experiencing things like swapping bodies or getting monstrous features in Ireland in the 1600’s.”
“Where did you read that?”
“In a book about Halloween. I borrowed it—”
“—from Hermione,” Draco finished for him, and Harry snorted. He cuddled closer to Draco, looking down at their feet. They wore the same size shoes, and the boots Draco was wearing for his costume actually belonged to Harry. Though his heeled red boots were decently comfortable he was not used to wearing them for this long, and he propped his leg up on his knee.
“Swap shoes with me,” he said, tugging at the knot of his laces. Draco raised an eyebrow, but then he pulled his arm from Harry’s shoulders to take the boots off.
Harry had just finished lacing up his shoes when the bus arrived, and he was happy to step into the heated interior and sit down on a cushioned seat. He sat by the window and Draco sat next to him, Harry leaning his head on his shoulder.
“Happy Halloween,” Draco mused, putting his hand on Harry’s thigh, and Harry sighed. He put his hand on top it, closing his eyes with a quiet yawn. Draco turned his hand over to intertwine their fingers, and Harry picked it up to kiss it, mumbling against his skin;
“Wake me up when we reach my flat.”
