Author's note: This chapter took me forever to get just right, but I think I'm finally satisfied with how it turned out. I hope you guys agree!
Stiles let Derek pull him into his bedroom, watching the subtle shift of muscles beneath Derek's skin, the play of ink between his shoulder blades with every ripple of muscle, every shift and pull. Stiles could smell his own nerves, could taste the tang of excited apprehension on the air. He had no doubt that Derek could smell it too, which only served to intensify the feeling.
Being nervous was stupid, Stiles told himself. This was Derek for Christ's sake. He trusted Derek with his life. Trusting him with this, with his body and his heart, seemed like a natural progression, an organic extension of their past and a perfect place to start their future.
A blow job on the couch was one thing, but sex in his childhood bed meant something else entirely, something bigger. Maybe that's what had Stiles shaken, what made his stomach clench and flutter with the realization of just how colossal this whole thing truly was, how much was riding on them doing this right.
Sex with Derek meant more than just sex, more than just two people coming together in a moment of passion. Sleeping with Derek, knowing how they felt about one another, how their wolves felt, it simply meant more.
Crossing that last line, breaking down that final boundary was irreversible, something that they couldn't take back. Stiles knew, beyond a shadow of a doubt and with every fiber of his being, falling into bed with Derek was a decision that would change the course of the rest of their lives. Once they made that choice, chose to come together instead of falling apart, they'd belong to one another in a way they'd never belonged to anyone else, a way they never would.
Stiles felt like he was standing on the edge of a precipice, balanced on a razor edge where leaping one way would guarantee a safe landing and the other promised to be chaotic and possibly disastrous, could tear him into tiny, jagged pieces while simultaneously being the best fucking decision he'd ever made.
As if sensing the storm raging inside him, Derek turned in the middle of Stiles' bedroom floor, his eyes patient and so gentle it made Stiles' nerves smooth out and his heartbeat spike in the same span of a mere second.
"Hey." Derek whispered, stepping into Stiles' space and lifting the hand not twined with his fingers to one blotchy pink cheek, his naked chest emanating heat that drew Stiles in, made him want to roll around in it. "We don't have to do this right now, not if you're not ready. If you just want to crawl into bed and sleep, that's fine with me, Stiles."
"No." Stiles denied, leaning into the warm cup of Derek's hand, closing his eyes and taking a deep, steadying breath. "I want to." he murmured, opening vulnerable whiskey eyes to meet Derek's gaze. "I want you so bad it physically hurts, Derek. I'm just..." he trailed off, turning his head to push his nose into Derek's palm.
"Nervous." Derek supplied, disentangling their fingers to reach for Stiles' hip, sliding around his back to pull him forward, their bodies fitting together seamlessly.
Nodding, Stiles blew out a shaky breath and leaned his weight into Derek's body, circling Derek's waist with his arms and hooking his chin over his shoulder. "Sleeping with someone has never felt like such an existential choice before." he complained halfheartedly.
Derek smiled, fingers trailing gently up and down the center of Stiles' back. "Whatever happens, tonight or any other night," he promised, his voice sure and heartbeat steady, "I'm not going anywhere, Stiles. You and I will always be you and I. Got it?"
A soft smile curled one side of Stiles' mouth. "Promise?" he asked, hoping it didn't sound as needy aloud as it did inside his head.
"Promise." Derek's grin was obvious in his tone, the arm around Stiles' shoulders squeezing as if to solidify his word.
A long moment of quiet stretched between them; Stiles trying to smooth over the frayed edges of his anxiety while Derek waited patiently, his fingers massaging Stiles' nape with reassuring weight.
"I've never been with a guy." Stiles admitted softly into the still, not-so-silence of his darkened bedroom, aware that he'd already made his choice, probably made it a lifetime before. "I've thought about it, even fingered myself open a few times. But, actual sex with another guy seems like something that's totally different in practice."
Derek huffed a small laugh, sliding a hand up into Stiles' hair even as his body flooded with heat. "We'll go as slow as you want to." he soothed, kneading Stiles' scalp gently as he pressed a kiss behind his ear. "Whatever you want, all you have to do is tell me, okay?"
Stiles and his wolf both shivered as warmth bloomed in their belly, a thousand and one images flickering through Stiles' mind. He saw Derek on his knees, face buried in Stiles' ass while his tongue explored as thoroughly as one could manage. Derek fingering him open, slow and leisurely, teasing Stiles with touches too gentle to get him off. Stiles riding Derek's cock with abandon, bouncing in his lap with his head thrown back and Derek's teeth buried in his throat...
"Anything?" Stiles ventured curiously, shifting his pelvis against Derek's hip so that his quickly hardening cock was rubbing at the cut of Derek's hip and thigh.
Derek's fingers clenched at Stiles' waist, not to still his movements but simply to hold on while all the blood in his body rushed south and his head swam with arousal, both his own and the heady scent of Stiles' as it swirled around them.
"Qualifications are for the weak." Derek said, his voice going low and rough as Stiles' hands migrated down to the high roundness of Derek's ass, fingers exploring with curious but determined touches.
Stiles laughed, his eyes sparkling with excitement. "What if I wanted to cuff you to the bed and rim you 'til you cried?" he questioned, the tips of his fingers dipping beneath the waist of Derek's track pants to tease at the very top of the cleft between his cheeks.
Breath hitching, Derek unconsciously rolled his hips back into Stiles' loose grip, a low rumble vibrating in his throat. "You got cuffs?" he asked, not caring one way or the other if he was calling a bluff or granting permission.
A high whine escaped Stiles' lips and his pelvis jerked forward, his cock jabbing Derek in the belly "Fucking Christ, Derek." Stiles said, nails biting into Derek's skin. "Later, I swear to God we're gonna do that." he vowed breathlessly before surging forward to crush Derek's lips with his own.
Like a switch flipping, their tongues met, slow and careful shifting quickly into frantic and demanding. Derek hauled Stiles up by his ass, giving him no choice but to wrap his legs around Derek's waist. In a quick blur of movement Derek was dropping Stiles on the bed and climbing over him, fusing their mouths together and scooping the growl right off Stiles' tongue while his body rolled sinuously down into the eager cradle of Stiles' parted thighs.
Derek couldn't be sure who actually managed to divest them both of their pants but they were somehow both gloriously naked a few beats later and Derek found he didn't care who made it happen so long as there was no longer any barriers between Stiles' hands and his skin.
Downstairs, Stiles had been pliable and simply let Derek work his body however he saw fit. Here, now, Stiles was a hurricane trapped inside his own skin, all frenetic energy and constant, churning motion. His hands tugged and shoved at every stretch of skin they could reach, nails scratching at the sharp wings of Derek's shoulder blades, down the tight cords of his back, digging into the globes of his ass and pushing him closer as Stiles ground upward. His teeth and tongue explored Derek's clavicle, sharp and grounding as he moved to Derek's throat, clamped his teeth into the fragile skin until Derek growled and his wolf echoed the sound.
"Stiles." Derek moaned, ragged and sandpaper rough, his hands spread wide and pinning Stiles' hips to the bed. "Tell me. Fuck, I need to hear you say it."
Stiles whimpered, his head filled with hazy lust while his heart beat a chaotic rhythm, his skin feeling too hot, his body burning up from the inside out. "Please, Der." he all but begged, continuing to roll his pelvis up into Derek's hands, gasping and choking when their cocks finally, blissfully slid against each other. "Please. I want you to fuck me. I need it, Derek."
Stiles couldn't have cared less that he was pleading, that his voice crackled and broke with desperation. His body was lit up brighter than the sun, even the barest brush of Derek's skin against his feeling like a shockwave. Stiles' body was quick to respond, his nerves raw and sensitive when they sparked and caught fire, Derek's gentlest touch triggering an earthquake somewhere deep in Stiles' chest.
Growling, eyes flashing brilliantly in the dark, Derek kissed Stiles hard, ignoring the copper taste of blood where his slightly-too-sharp teeth cut the inside of his bottom lip. He tore himself away, panting into the nearly nonexistent space between them while he strived for control.
"Up on your knees." he commanded hoarsely.
Stiles scrambled to comply when Derek lifted his body off of him, flipping onto his belly and pulling his knees up so that his ass was thrust high. Derek groaned, exerting a herculean effort in order to stop himself from simply impaling Stiles on his cock then and there, saying fuck it to working him open and just plunging into his tight little hole without a second thought. Shaking his head to wipe away that image, Derek forced himself to reach for the nightstand, following his nose to find the bottle of lube Stiles kept tucked inside.
Over his shoulder he caught Stiles' eye and held up a condom, quirking one brow in question. Stiles didn't even pause to consider it, simply shook his head and then wagged his ass invitingly, grinning devilishly, his eyes bright and sparkling even in the dark.
Derek's wolf whined, the sound echoing around the inside of his head as he crawled back across the bed and positioned himself between Stiles' legs, dropping the bottle of slick beside them on the mattress.
"I wish you could see yourself right now." Derek rumbled, one hand grasping Stiles by the hips to angle his ass up higher while the other planted between his shoulders and pushed him down to the mattress. "See how fucking gorgeous you look like this, how perfect." he praised, thumbs hooking into the valley between Stiles' cheeks, easing them apart so he could get his eyes on the puckered hole begging for his attention.
Stiles whimpered again, pitched high and needy as a bright flush spread across the back of his neck, down between his shoulders to drip color all along the line of his spine.
Derek brushed the dry pad of one thumb over Stiles' asshole, pressing gently before easing back. "Can I put my tongue here, Stiles?" he asked, his cock jumping eagerly at the idea. "Do you want me to work you open with my mouth? Fuck you with my tongue before I stuff you full of my cock?"
"Jesus fucking Christ, Derek." Stiles didn't care that his voice came out reedy and pathetically whiny. He didn't care how frantic and needful he sounded, how brazenly he presented his backside for Derek. All he cared about was the feeling of Derek's hands on him, touching him in ways he'd only ever been touched by his own hand, making his skin hum and burn.
"Say it." Derek prodded, licking his thumb and then pressing it back to the knotted ring of flesh, swirling it gently.
"Yes!" Stiles nearly shouted, rocking back into the slippery rub of Derek's touch. "I want you to, okay? Just fucking do it."
Derek growled deep at the demand in Stiles' tone, buzzing tendrils of pure lust unwinding in his belly. He gave Stiles a sharp slap, his palm searing it's print into one mound of flesh and then soothing it away. The startled yip Stiles let out was darkly pleasing, had Derek's gut clenching and his heavy cock twitching interestedly between his legs.
"Asshole." Stiles gasped out, breath stuttering in his lungs and getting stuck in his throat when he felt Derek shift around behind him, immediately followed by the hot velvet glide of a tongue as it laved at his hole.
Derek made a deep humming sound that carried up Stiles' vertebrae like ivy vines, winding and twisting around his nerves. He mewled and cried out, his back bowing sharply when Derek pushed the very tip of his tongue into Stiles' body, licking wetly at his walls and slithering back out to circle his rim again.
Derek took his time, reminding himself over and over again that this was Stiles first time like this, that he had to make it good, had to make sure it hurt as little as possible. It didn't matter that Stiles was a wolf now, that he could heal. Derek didn't want to cause him any more pain than necessary. He ignored the begging whimpers and choked off demands tripping from Stiles' lips, gripped him tight by the hips and held him still while he swirled and rolled his tongue, lapping zealously at Stiles' puckered hole.
By the time Derek finally pushed one fingertip past the wrinkled skin of Stiles' rim, it was loose and drenched, pliable and receptive to Derek's seeking digit.
"Holy God." Stiles moaned, rocking up to take the finger in deeper. "More." he begged, spreading his legs wider to gain more leverage.
Derek obliged, delving deeper and twirling his finger against the satin smooth heat of Stiles' insides. "Do you like that, Stiles?" he asked, giving shallow thrusts inside him. "Do you like having me, any part of me, inside you?"
"Yes." Stiles nodded furiously against the pillow trapped between his face and the bed. "I love it, Derek. Please."
The second finger slipped in with only a bit of resistance, pushed right in beside the first, both of them crooked and unerringly finding Stiles' prostate. His body shook, overwhelmed with sensation and yet needing so much more. Breathing got more and more difficult with every push, every delicious drag of Derek's fingers in his ass. Derek murmured gentle words into his skin, mouthing at Stiles' cheeks, tonguing around the skin stretched taunt where his fingers disappeared inside Stiles.
"Do you want three?" he asked, already flipping the cap on the lube, unable to smell even the plasticy scent of it over the want and need pouring off of Stiles in spectacular clouds.
"I wanted three ten minutes ago, Derek." Stiles growled, shoving back hard on Derek's hand, shivering a little at the cold lube he could feel drizzling into his crack.
Derek chuckled richly, smoothing the flat of his free hand up the center of Stiles' back to grip his hair. He yanked, pulling Stiles head back as he draped himself all across his back, stretching Stiles open with three fingers, thrusting them more roughly than he had since they started.
Stiles keened, spine snapping into a hard curve as he arched into the penetration, his body clenching tight around Derek's fingers. His rim burned a little, nothing he couldn't handle but more than it ever had whenever he'd done this to himself.
Derek, scenting pain on the air, tried to gentle his touch but Stiles snarled his objection.
"I'm fine." he grit out through partially extended fangs, proving his point by rolling his pelvis up and back, his walls clutching at the fingers inside him. "Don't stop. If you stop I swear to God I will rip your throat out."
Eyes glowing instinctually in response to Stiles' flashing Gold, Derek shoved his fingers into Stiles harder and bit down ruthlessly at the slope of his neck. Gasping and whining, Stiles tipped his head to one side, baring his throat submissively.
"Bastard." he panted, holding the position despite the epithet, bucking on Derek's fingers while they moved brutally inside him.
Derek was painfully hard, every molecule in his body straining to be inside Stiles, his wolf alternating between whines and snarls, urging Derek to take, to claim, to mark Stiles as theirs. He'd held back for fear of hurting Stiles, his mind still struggling to recognize Stiles as a wolf instead of the fragile human boy he'd left behind. He didn't want to scent pain on the air, clouding up Stiles' scent and covering the undiluted lust pouring out of his skin.
But when Derek's iron grip on his wolf's reigns slipped, when he gave into his instincts for a fraction of a second and buried his teeth in Stiles' neck, Stiles' scent hadn't gone murky with hurt. It hadn't rippled with the sour sting of pain, nor had Stiles so much as flinched. Instead, the aura of scent around Stiles went smoky and rich with pleasure, his pulse kicking up excitedly as he moaned and shoved his ass up higher, the hot flush of arousal flashing through him so savagely Derek felt it pulse along his skin.
Pleasure-pain apparently did it for Stiles, a fact that Derek was more than willing to explore for both of their benefit. Reminding himself for the umpteenth time that Stiles was a werewolf, was no longer human and breakable, Derek withdrew his fingers from his body without warning and flipped Stiles over, startling a high-pitched gasp out of him.
"Wha-" Stiles tried to ask, only to stutter off into a rumbling moan when Derek's cock replaced his fingers, sinking in and splitting Stiles apart without preamble.
Stiles felt like he was coming apart at the seams as his body stretched around Derek's considerable thickness. It hurt, a deep, visceral ache that seared through him and made his eyes water, but it was good, so fucking good Stiles never wanted it to end. The flare of pain faded quickly, morphed into pleasure that poured through him like liquid gold, coating his insides with delightful heat.
Derek grunted as he bottomed out, his thighs flush to Stiles' ass and his face buried in the hollow of Stiles' throat.
A soft gust of air puffed across Derek's shoulders, a gentle "Oh." carried on an awe filled breath.
He didn't need to ask, didn't need Stiles to tell him. Deep inside, in a place Derek never even knew existed, he felt it. He felt gravity shift around them, felt the Earth shudder with the weight of it. It was different, so devastatingly different from anything he'd ever felt. It was bigger, more intense than anything either of them had ever experienced. It was coming home and falling in love, it was finding peace and letting go and an endless free fall into forever. It was a volcanic eruption, a seismic event, a full blown tsunami that ravaged the land and laid everything to waste.
Being inside Stiles... It was finding the place where he belonged, the person he'd belonged with all along. It was honesty and passion and trust and Stiles; Everything Derek wanted but hadn't known he needed, all wrapped up into one world shattering package.
Guided by nothing but primal instincts, his coherency lost in the push of his wolf beneath his skin and the revelations taking place in every cell in his body, Derek began to move. Any intention he had to take this slowly, to draw it out and make it last, deserted him with the first torturously perfect drag of Stiles' walls around his cock. It felt like Stiles' body simply refused to release him, his clutching heat clamping down around Derek's shaft and drawing him back in.
Stiles' vocabulary was reduced to broken fragments of fumbled vulgarities and Derek's name, his entire form quivering with the release building deep within his core. Every snap of Derek's hips punched a shredded, fractured sound from somewhere in Stiles' throat. He arced into each punishing thrust, their bodies crashing together with enough force to knock the headboard against the wall with a sound like a whip crack.
Derek's mouth worked over Stiles' neck and shoulders, his tongue darting out to lave away crimson beads wherever his fangs caught and tore the skin, his fingers gripping Stiles' thighs, pulling them up and apart so hard that bruises formed and healed between thrusts.
Stiles' own claws were extended, raking deep lines into the sweat slicked expanse of Derek's back. His thighs clenched Derek around the ribs, heels digging harshly into the high roundness of Derek's flexing ass.
A deep baritone rumble was building in Derek's chest as they writhed together, their skin slipping and sliding, the heat between them building to a fever pitch.
"Harder." Stiles managed to gasp out, the fire in his bloodstream igniting the whiskey in his eyes until the only visible ring of color burned Gold. "Derek, I need-"
Derek snarled and pistoned his cock into Stiles with as much power behind it as he was capable, forcing Stiles higher up on the mattress with his momentum and ripping a strangled moan from his lips.
"Yes. Fuck." Stiles cried through bared fangs, fingers scrabbling at Derek's back as he bucked up into his unrestrained thrusts, chasing the orgasm he could feel coiled tightly in his belly.
"Come, Stiles." Derek said, the command falling from his lips on a growl he couldn't even hope to control. "I've got you, just let go. Wanna feel it."
Stiles shuddered, a gravely whimper tearing up his throat. He couldn't reach between them to stroke himself off, the claws on his fingers making that more dangerous that it was worth. Instead, he made it work with the friction of his leaking head against Derek's abs, the shift and roll of their bodies together almost enough.
"I can't-" he choked on the words, Derek's cock hitting his prostate head on. "Need more." he begged, clawing into Derek's shoulder blades, holding on while Derek fucked into him with chaotic, desperate thrusts.
Without so much as a moment's thought, Derek pushed himself up, pulling his face out of Stiles' neck so he could tilt his head and bare his throat.
The sound that clawed its way out of Stiles' chest was inhuman, shattered and destroyed, a wounded sound that echoed through Derek's bones, ricocheted around the inside of his rib cage. "Derek."
Stiles' orgasm slammed through him with a ferocity that stole the air from his lungs, shredded him into tatters and left him ruined. His vision went blurry as wave after wave of pleasure crashed through him, coming so hard he striped his own chest with thick, sticky lines as he arched against Derek's chest, his muscles shaking with the force of his release.
Derek's eyes rolled back in his head when Stiles gripped him by the hair and jerked his head to one side, his fangs sinking through Derek's skin like molten lead through ice. Stiles' hole spasmed around Derek's cock, his scorching, velvet walls closing around him, pulling his own orgasm from somewhere near his toes. Derek shot his load buried as deeply as anatomy would allow, filling Stiles' up and marking him from the inside, a fucked-out shout reverberating in the room, mixing beautifully with the tiny whimpers and breathy whines tumbling from Stiles' lips.
Derek shook his way through it, shuddering ceaselessly as pleasure rippled through him, white hot and seemingly endless. He felt Stiles' teeth slide out of his throat, caught the satisfied gleam in liquescent amber as he licked the last traces of Derek's blood from his, once again, human teeth.
Arms trembling too violently to hold him up, Derek let his weight fall onto Stiles, pinning him to the bed without even bothering to pull out. He sank onto Stiles, face mashed into his throat so he could nose at his skin, mesmerized by the way their scents mingled.
"Holy fucking shit, Batman." Stiles heaved out, still trying to catch his breath.
Derek snorted, snuffling into Stiles' skin. "I thought you were Batman." he mumbled lazily, too content to muster the energy to make it a question.
"Shut up and let me bask in the afterglow." Stiles admonished, swatting limply at Derek's head. "Why did no one tell me werewolf sex was so intense? That should be in a pamphlet or something. I was in no way prepared for that."
Derek grunted, somehow not at all surprised that Stiles could talk his way through post-coital bliss. "It's not always like that." he mumbled, dry lips catching on Stiles' skin, drawing a shiver out of him. "Never was before, at least."
"For me either." Stiles admitted, fingers carding through Derek's damp hair contemplatively. "Sex as a human was nothing like that."
Derek hummed noncommittally, though he agreed. In the brief time he'd been human and sharing his bed with Braeden the sex had been good, but it was in no way comparable to what had just happened between him and Stiles. Sure, sex had always been pretty good, but it never felt like the Earth's poles were reversing, the entire universe turning inside out around them.
"Shit." Derek could feel Stiles cringe below him, evidently realizing that talking about past sexual experiences while your current one was still inside you was right up there with the very worst of all the terrible ideas. "Sorry. That was stupid. I shouldn't hav-"
"Stiles?" he interrupted, lifting himself up to look down at the gorgeous boy spread out below him, still spread wide around him.
"Yeah?" Stiles grimaced, bracing.
Derek kissed him, slow and wet, as possessive as it was soothing. "Shut up." he whispered onto Stiles' tongue, catching his bottom lip between his teeth and biting down gently.
"Right." Stiles agreed immediately, fingers finding their way back into Derek's hair. "Shutting up."
Werewolf refractory periods being what they were, not to mention the high they were both riding right then, Derek wasn't at all sure they'd be able to make good on the Sheriff's request that they sleep. Especially when Stiles, little shit that he was, was writhing under Derek, smirking against his lips and rolling his hips down on the rapidly filling cock still buried inside him.
