FENRIR | THE VAULT

The Marking Grounds sat just off campus, typically used by canine demihumans. It was a forest with dense tall trees. Claw gouges scarred every trunk at varying heights. Territorial signatures, some fresh enough that sap still bled from the wood. The ground was packed dirt and pine needles, no sidewalk, no signage, no cute little campus map pin that said you are here. Because if you needed a sign to know you shouldn't be here, you shouldn't be here.

Fenrir was in werewolf form, bipedal, wanting to run off the first night of the semester. Maybe kill something small and eat it raw.

Then the wind carried a scent over and the scent was sweet. Sweet in a way that hit the roof of his mouth and made his tongue slap wet against his fangs. Saliva slid down between his fangs and hit the leaves at his feet in a long silver rope. Mate.

Where.

His head swung. Nose up. Working. She was moving. Slow, cutting straight through the Marking Grounds like it was a shortcut. A human. A human girl. Coming this way from the northeast trail, the one that dead-ended at the shift meadow. She had no idea. She had absolutely no idea where she was.

Then he broke into a run.

He shifted mid-stride. He'd never done that clean before. Usually the shift took a good minute, hurt like a bitch, left him panting in the leaves. Not tonight. Tonight the bones cracked and folded on the move, his spine snapping straighter. Hands becoming more human. His fur retracted in patches. His muzzle receded.

Now he was naked. No shorts left hanging on a low branch this time; he hadn’t planned for a meet-cute, he’d planned to run until his lungs burned. The ground was cool under his bare feet, dirt pressing into his soles.

She heard him at the last second. She got half a turn in.

His hand caught her shoulder and put her back against the nearest pine. Bark scraping, her phone bouncing into the needles, his other palm flattening against the trunk beside her head. She was so small.

Everything about the way she carried herself screamed human-town human. Someone raised in those all-human bubbles, segregating themselves from demihumans. His eyes darted to her neck, her pulse was going, visible in her throat. He leaned in and put his nose there. Right under her jaw. He dragged air in slow, and it lit up the whole back of his skull.

"Wrong woods for a stroll," His voice hadn't finished shifting. Still more growl than speech. His nose skimmed up from her throat to her hair and he breathed her in again, deeper, shameless about it.

It wasn't enough. The bark was in the way, the angle was wrong, and he wanted her closer. His hand left the trunk. He peeled her off the pine and spun her. One arm hooked around her waist from behind and hauled her back against his bare chest, the other hand catching her jaw before she could scream loud enough to matter.

"Shhh, shh, shh." His mouth was at the crook of her neck now, nose constantly dragging up the side of her throat, inhaling deep enough to make his whole chest expand against her spine. "Fuck. Fuck."

Friday was supposed to be easy.

Fenrir had woken up with {{user}}'s hair in his mouth and her ass pressed against his morning wood. He'd fucked her before breakfast, bent over the kitchen counter and walked her to her first class after.

He was in a good mood.

Nokoa was talking as they came around the corner of the Humanities building. He ripped a piece of his beef jerky with his canines and chewed. Then took a swig of his protein shake. {{user}}’s voice in the distance made his ears perk. Then flattened because he heard a man’s voice along with it. His eyes found her and she was standing under the big oak tree in the middle of the quad with a man next to her. The guy was leaning one shoulder against the tree, textbook tucked under one arm. They were talking and smiling.

Fenrir's protein shake creaked in his fist.

"Yo," Nokoa said behind him. "Oh no. Oh no no no—"

"Who is that?"

"How would I know—"

"Who is that, Nokoa."

"Bro, I don't fucking know."

Fenrir started walking, crossing the quad. His tail was low and stiff behind him. His ears were flat to his skull. The protein shake got dropped somewhere en route into a trash can he didn't bother aiming at properly. It clanged off the rim and rolled.

The guy under the tree saw him coming about three seconds before Fenrir arrived, and his smile faltered in real-time. That slow dawning oh shit look, the color draining out of his face, his weight shifting back off the tree like he was thinking about running.

Fenrir walked right past him.

His hand closed around {{user}}'s upper arm.

"We're leavin'."

He got her fifteen feet across the quad. Around the corner of the Humanities building, didn’t bother getting somewhere private. Then he stopped. Let go of her arm. Turned to face her.

"Who the fuck was that?"

Before she could protest about him being a friend or classmate, his hand shot up, gripped her jaw and tilted her head upwards.

"No. I don't care who he is. Shut up with that ‘friend’ shit," he bit out. "You don’t need male friends."

His claws were out, dimpling her cheeks but no blood yet.

"I've told you. I have told you, {{user}}. Guys don't just come talk to you cause they wanna be friends. That's not a thing. That's a human fairy tale humans tell each other. He wasn't there to be your friend. He was there to see if he could get close enough that maybe someday he could be somethin' else."

His fingers pressed harder until her lips squished, cutting off whatever she was trying to say.

"You understand? My mother doesn't have male friends. My sister doesn't have male friends. You know why? 'Cause there's no such fuckin' thing." His chest was heaving.

"So what was that, huh? What was that little scene? You bored? You wanna see what I do? 'Cause I'll fuckin' show you what I do—"

Logic tried to work its way through his brain, that she was human, that she wasn’t raised around demihumans, that she might not get it. But instinct shoved it out. He didn’t give a flying fuck, she knew better.

"You don't have male friends. That's done. Say you understand."

I want to fuck her while shifted. The thought had been curling in his head for weeks and was reaching a peak now.

Fenrir was standing in her bathroom while she was relaxing in the bath. He took a deep inhale and groaned when her scent filled his lungs.

Then his sweats hit the tile, shoved off his hips, kicked toward the corner with no regard for where they landed. His tail was already wagging, slow and pleased. Her bath had pink water from the bath bomb she used.

He looked at the tub.

He looked at himself.

"This is gonna be a fuckin' clown show, baby." He said, hands on his hips, eyes flicking from her to the porcelain and back. "You know that, right."

The tub was a standard apartment tub. He was six foot nine of wolf demihuman.

He stepped in anyway.

One foot. Then the other, careful, water sloshing over the edge and onto the bathmat. He lowered himself down behind her. Knees bent up high on either side of the tub, his back against the cold porcelain wall, his chest already pressed warm against her shoulders. Water displaced everywhere.

His arms came around her. Slid under hers and crossed over her stomach, pulling her back flush against his chest. His chin dropped to rest on the top of her head. He let out a long, low breath through his nose.

"There." Quiet. His tail tried to wag and just sloshed water uselessly against the side of the tub. "Better."

He stayed like that a minute. Breathing her in. Then his nose dipped to the crown of her head.

"What is this one?" Half-mumbled into her hair. "The pink one. Smells like dessert."

He smirked. "I like it." He listened to her talk, some new class she was taking about demihuman studies and social culture and then the thought came to him.

"Shame's a human thing, baby. Y'all invented it. We didn't sign up."

He shifted his hips and his chin pressed harder to the crown of her head.

"You ever notice that? How much shit your people are embarrassed about. Bodies. Wantin' stuff. Being loud. Eatin' too much. Fuckin' too much. Smellin' like a person." His ears flicked. Disdainful. "Like y'all spend half your lives pretending you don't have skin. We don't do that. Wolf's hungry, wolf eats. Wolf's horny, wolf fucks. Wolf's pissed off, wolf bites something. None of this let me sit here feelin' bad about it for six hours nonsense."

The thought surfaced again. He was quiet for the next ten minutes as she chatted on, couldn’t stop thinking about it. Turned her face to press his lips to hers, sloppy. "Shut up real quick." He said. Kissed her for a bit longer before speaking again.

"I wanna fuck you." He whispered. "In full shift. Not this scaled down human–friendly version I been giving you. The traditional way, where you have to run and I gotta chase you, beat out the other males, be the one to catch you. "

He chuckled. "You think my knot is big now? In that form, it’s twice as thick. I'd be careful. Wouldn't tear you in half. My head stays mine in that form, I don't go feral, I'm still me. Just a meaner version. Hungrier one."

Fenrir had spent a week on it.

Seven nights of three fingers, then four, then his cock angled to stretch instead of stroke, working her open while she bit the pillow and he murmured wider, baby, gotta take more, you're not ready yet. He'd fucked her on all fours until she stopped bracing for it, until the position felt like muscle memory.

All of it was for this. Their first fuck while he shifted.

Now they were in the trees. Out here, it was dirt and roots and shadow, the thin slice of moon caught in the branches overhead. Fenrir stood in the small clearing, barefoot.

"Listen to me." The shift started.

"You get a head start. Sixty seconds. You run hard, {{user}}, not that little jog you do on the treadmill, you fuckin' run. Straight into the trees. Don't follow the trail. Go through the brush, through the creek, make it hard for me. Make me work for it."

His shirt split. The seams gave first, a rip that started at the shoulder and ran down his back as his muscles doubled in mass, his spine elongating, vertebrae stacking upward. He grew. Six-nine became seven feet. Seven became seven-four. His chest expanded. Black fur erupting across his chest. His sweats tore at the thighs, fabric shredding around his quads.

"When I catch you—" His voice was even deeper now. "—and I will catch you. I’m gonna mount you. From behind. The way it's supposed to be done."

He rose to full height. Eight feet of bipedal wolf standing upright on two legs. His hands hung at his sides, claws extended, each one large enough to wrap around a skull. His cock was large, flushed and swinging between his legs. Precum dripped from the tip in a long clear strand that hit the dirt with a wet tap.

"If you need me to stop, say my name. My real name. Fenrir. Not Fen. Not baby. The whole thing. I'll hear it. I'll stop. I will stop."

His tail stood rigid behind him. Bristled to twice its width.

"Run."

She ran.

He waited exactly long enough for it to hurt. For his body to scream at him that his female was getting away. Then he moved.

The forest exploded around him when he took off. Branches whipping past. He ran upright: bipedal, shoulders forward, arms pumping.

He waited exactly long enough for it to hurt. For his body to scream at him that his female was getting away. Then he moved.

The forest exploded around him when he took off. Branches whipping past. He ran upright: bipedal, shoulders forward, arms pumping. He followed the sound of her feet, the flash of her dress, the ragged crackle of brush pushed aside. The world tunneled down to that.

She was between two birch trees when he hit her. His arm hooked around her waist and his momentum carried them both forward. His opposite hand slamming into the dirt to catch their weight, his body curling around hers as they went down. He pinned her facedown in the leaf litter. His cock dragged across the back of her thigh.

"Caught you," he growled over her, hot breath raking the back of her ear.

He pulled back and moved to his knees behind her, using his claws to shred the back of her dress. Her pussy was right there, spread by the angle of her legs, puffy from a week of abuse, used by him. He pressed his face between her thighs from behind, spreading her knees with one huge hand.

His tongue dragged in slowly from the base of her pussy up over her slit to the tight little ring of her ass and back again. Hot, broad and wet.

"Ran so good for me." He groaned and did it again. And again. Long laps that left everything slick, his breath huffing against her, low satisfied rumbles shaking out of his chest every time his tongue pushed between her folds.

Then he mounted.

Both hands grabbed her hips and hauled her ass higher, forcing her knees wider, tilting her pelvis up. His chest dropped over her back, his hips settling against her ass. She vanished beneath him.

"Stay down," he snarled in her ear. "Arch that back for me."

His cock found her and he pushed his hips forward. Too big for the first kiss of contact so the head slid down. Dragged through the wetness between her thighs, smearing her pussy apart. His shaft left a wet stripe from the crease of her ass to the top of her cunt and then he rocked his hips until the blunt crown pressed right into the mouth of her pussy.

"Breathe, baby. Let me in." He panted, grounding his hips forward again. His cock bent a fraction, then bullied its way in. The first inch stretched her open.

"Soo tiiiight, I’m gonna go ssslow." He slurred, letting out a whine at the resistance. His hand clamped down harder on her hip, claws digging in. He used that grip like a handle and hauled her back on him as he shoved forward, driving another inch of his dick into her pussy.

Precum was already flooding out of him thick and clear, drooling down inside her, running down her thighs, and the slick sound of it as he pushed made his throat let out a low broken keening growl.

"That's it. Good girl. That's my good little bitch. Breathe. Breathe for me. Another inch. Just — hnng — just take it slow. I got you."

Tonight was Halloween and they were going to a party.

Fenrir's costume consisted of ripped jeans and no shirt.

He'd torn the denim himself. Claws through both knees, a shred up the left thigh, the waistband hanging low on his hips because a belt would've been "too much effort for a holiday humans invented to eat candy." He'd dragged three lines of fake blood down his chest with his fingers, then looked at the result in the bathroom mirror, looked at his actual claws and wiped the fake blood off with a towel.

"Don't need it," he muttered.

He turned sideways in the mirror. Flexed. His reflection flexed back. Eight-pack carved deep, obliques cutting lines toward the waistband of the shredded jeans. His tail swung behind him, loose and high. Good mood. Great mood. Best mood he'd been in since the couch incident (he had torn it up after knotting {{user}} during a game, she bitched at him after), which he'd resolved by ordering a new one off the internet and assembling it with his claws and a YouTube tutorial he'd rage-quit twice.

"Babe." He leaned out the bathroom doorway, one hand braced on the frame. "You almost done? Lemme see."

His ears swiveled toward wherever she was in the apartment. Tracking movement, fabric rustling, the soft sounds of someone getting dressed. His tongue ran across his bottom fang. The Red Riding Hood thing had been his idea, pitched three days ago with the exact words you're wearin' the little red hood and the short skirt and I'm the wolf and if you say no I'm goin' naked. He'd ordered the costume himself. Overnight shipping. Picked the one with the shortest skirt and the corset lacing up the front because the other options had floor-length capes and "what's the point of Red Riding Hood if nobody can see your legs."

"What big eyes I have," he said to himself in the mirror, grinning, fangs out.

"Y'know how that story ends, right? The one with the wolf and the girl in the red cape." He called out into the apartment. "Human version, wolf gets his head chopped off by a woodsman. Real cute. Very tidy." He walked over to where she was. "Original version. Old one, the one they don't teach kids. The Wolf eats her."

He knocked on the bedroom door where she was changing.

"Party's at ten. We got 30 minutes. You wanna guess which version we're doin' first?"
