Pairing: Derek Hale x reader
Rating: Mature for heavy swearing, graphic sexual content
You looked up from your Chemistry homework as you heard a cough behind you. Derek Hale was leaning against your doorway with his head cocked to the side, staring at you thoughtfully. You rolled your eyes and resumed your schoolwork, already knowing why he was here.
“Go away,” you mumbled.
“No, I’m good right here,” he announced. You ignored him.
A few beats of silence passed.
“[y/n],” he pressed. You gave him nothing, absentmindedly scanning your notes.
Suddenly, you felt yourself being jerked backwards and around, coming face to face with your intruder.
“What the hell?” you rebuked.
“That’s better,” Derek chimed. “Now, tell me what’s wrong.”
“I don’t know what you mean,” you deadpanned, somewhat surprised you could still deflect his questions, given his persistence. Then again, you were always good at avoiding things, a skill useful for dodging the rest of the pack’s investigation. You didn’t back down when Scott offered to give you a ride home just as an excuse to prod you, when Isaac cornered you at your locker with his sad puppy eyes, or even when Allison tried to literally hug information out of you.
You crossed your arms over your chest and stared stonily at Derek, unimpressed by his interrogation tactics.
You couldn’t even process the next few seconds as he swiftly grabbed the arm of your swivel chair and abruptly pulled you towards him, backtracking to your bed. He sat down so you were eye-level.
Your eyebrows nearly disappeared into your hairline.
“Let’s try that again,” Derek enunciated slowly. You crinkled your nose at him because what the fuck is his problem?
“What the fuck is your problem?”
“What the fuck is your problem?” Derek scoffed. “Even without the pack telling me you’ve been weird and distant lately, it’s obvious you’re not yourself.”
You cursed inwardly. The pack had ratted you out. You shouldn’t be surprised since everyone basically flocked to Mommy Derek at the first sign of trouble. They were cute that way.
“Still,” you huffed, shifting uncomfortably in your seat under Derek’s scrutiny. “You didn’t have to manhandle me–”
“Just tell me what’s up,” Derek continued nonchalantly, glossing over your complaint. “Your heart’s beating really fast and you’ve reeked of anxiety for days. If there’s a problem, you’re supposed to tell me. I’m your Alpha.”
Goosebumps rose along your spine at his words. I’m your Alpha. The phrase echoed in your mind. It manifested in images of Derek whispering it in your ear while he fingered you from behind, rasping it out while he held your head down to fuck your mouth. You closed your eyes, frustrated by how much Derek’s authority affected you. Fucking Alpha.
Your eyes shot open. You hadn’t meant to say that out loud.
“No! I–that wasn’t, um…” you stuttered, fumbling for ways to reverse this conversation, reverse time itself. But there was nothing you could do. Your mind went blank, not granting your mouth any usable intelligence. You felt pressure in your brain, like a blood clot that would explode if you didn’t say something soon.
In a surge of word vomit, you hurriedly blurted out, “IthinkI’minlovewithyou.”
And that’s when things came to a screeching halt. So much for deflection. Smooth move, genius.
Derek looked baffled as his shoulders elevated in tension, eyes the size of saucers.
“You’re… what?” Derek brows furrowed, seemingly searching your face for any cues that you were joking or high.
If only. Fuck it, nothing you say at this point could make this any worse.
“I think I’m in love with you,” you enunciated carefully. “Or–it could be something else. I don’t know. I’ve never felt this way before and it’s really freaking me out. I didn’t know what to do, so I just avoided you. And the pack. And just all of it, in general,” you rambled, wringing your hands together.
In response, Derek’s mouth parted slightly, his two front teeth peeking out like he was about to say something, but retreated again.
And then emerged the quintessential Derek frown. He was so adorable when he was mad, even when you were the reason.
“Look, [y/n],” Derek coughed, continuing sternly. “You don’t have to… explain. It’s okay to be confused. I’m not–I’m not mad at you.”
It was comforting that he was also stuttering over his words. Meanwhile, you tried not to swoon at how young and boyish he sounded when he was frazzled. But why wasn’t he more freaked out. He should’ve at least been a little angry. It usually took less than this to set him off.
“You should be mad!” you assured. “Get mad. I totally deserve it. For avoiding you, then lying about it. And for… being in love with you? Because I know what you’re thinking, these teenagers and their hormones,” you said gruffly, wincing as you accidentally did a poor impression of Derek. He raised his palm up incredulously, communicating that yes, you should indeed be embarrassed.
This was getting out of hand. You were all over the place and the more you tried to clarify, the more agitated Derek seemed to become.
“This is ridiculous. I don’t know what I’m saying. I’m too young for you and I need to stop kidding myself. I know that… I know,” your voice strained. You weren’t sure what burned more, your cheeks or the stinging behind your eyes.
The truth is, you did have feelings for Derek. And it was rather terrifying.
Because it would be obvious to anyone that Derek Hale was the perfect human specimen, with his tall, burly frame and Greek God jawline, armored in leather jackets and boots. That was your first impression when you met him. You, on the other hand, must have looked disastrous.
Before the pack and Derek, you were in a foster care system that left you abused and broken. When you decided to run away, you had no prospects or money. It was Derek that had found you, lost and dying in the woods. All you saw were sharp teeth and red eyes before you blacked out.
When you’d woken up, you were warm and safe. He had given you the bite, but also so much more. He had taken you under his wing and polished you off, given you guidance and shelter. It took a while to trust him, but when you did, he promised to turn you from a scared runaway into a warrior. And he delivered.
He introduced you to the pack, the family you never had. He taught you how to defend yourself, showing you strength you only dreamed about. But he also told you to use the bite to help other people, that power didn’t have to be destructive.
When you were human, you cowered away from people, fading into the background. You couldn’t trust anyone, couldn’t even trust yourself. But with Derek’s help, you learned to fight, speak your mind, and trust your instincts.
And therein lies the problem. Every time you were around Derek, every instinct in your body told you to jump his bones. You physically ached for him, your body buzzing with anxiety whenever you tried to stifle your need.
It wasn’t even just the physical stuff. Underneath his tough exterior, Derek had a heart of gold. You’d seen enough cruelty to know that Derek was the opposite. He was the most generous person you’d ever known, sharing his home with a bunch of misfit teenagers, nursing lost puppies back to health.
Even though Derek had rescued you, he’d never indicated that he was remotely attracted to you. He just regarded you as another annoying Beta through lectures and demands. Every once in a while, if you reached a new milestone, socially or physically, he would pull you into an awkward hug or stiffly pat your head while you tried to cough away your laughter.
It was obvious he would never return your feelings, so you spent an embarrassingly large portion of day figuring out ways to avoid Derek, which led to avoiding the pack because they were always together. But attendance was required at pack meetings, so you sat as far away from everyone as possible and looked down the whole time, only speaking when directly addressed.
Everyone was bound to notice your strange behavior eventually. You just didn’t expect Derek to confront you about it directly, assuming he wasn’t into pack drama.
Once again, you’d underestimated his capacity to care.
And judging from the way he was clenching his fists and gazing a hole into his jeans, apparently he’d underestimated your capacity to complicate his life.
The last thing you wanted to was to make things harder for Derek, but this confrontation resulted in exactly that.
“Look, let’s just pretend this didn’t happen, alright? Everyone has psychotic episodes sometimes,” you laughed nervously. “I won’t avoid you anymore–unless you want me too. I’ll leave you alone. Or, should I move out? Yeah, I’m going to move out. I’ll just go now, sorry.”
Without even looking at Derek, you rushed to your door, wiping the dew that had gathered at the corner of your eyes. You reached for your doorknob, but staggered backwards as you felt a hand close over your wrist. You yelped and closed your eyes as you gracelessly collided into something solid.
Your arms tucked into your chest, instinctively protecting you from the impact. You opened your eyes when you felt a breath fan over your forehead, and realized that Derek had you cradled against his chest with an arm locked around your back.
“You’re not going anywhere,” he grunted as he slammed his lips to yours.
Your went catatonic with shock, body rigid in Derek’s arms.
You were in Derek’s arms. Derek Hale’s arms in that blue Henley shirt that felt so soft and warm against you and his mouth, full and moist, pressing against yours–
You were broken out of your trance when you felt Derek’s wet tongue graze your chapped bottom lip. Oh.
You unfolded your arms and threw them around his neck, lunging forward to finally comply with his movements. Your tongue snaked out to meet his, eagerly applying pressure and then retreating again, battling then teasing. Derek signaled that your efforts were fruitful as he growled into the your mouth, the sound traveling from the back of his throat to your core.
It was all dueling tongues and gnashing teeth. Of course this is how Derek would kiss, intense and ardent, almost clinical in the way he switched between squeezing your hip and biting your lip.
And then oxygen was becoming an issue. Your body felt warm, too warm. Too much was happening too fast. You placed your palms against Derek’s chest, using all your strength to shove him away.
He faltered backwards, a look of astonishment twisting his features.
“What the hell?” he asked. He glared at you, but you could only focus on his chest as it heaved up and down, trying to calm your own breathing.
“Are we doing this?” you asked, voice wavering with emotion. “Because you’re still my Alpha. And I’m still a teenager.”
“You’re 18,” Derek deadpanned.
“I’m still in high school!” Derek’s gaze softened as you raised your voice.
You just couldn’t just rush into this. This was too important. You needed to know Derek’s intentions, because you didn’t just want a hurried groping session, a one night stand. You wanted all of it, all of him. Anything less would just cheapen your feelings.
For once, you actually believed that you deserved better than a guy just using you and throwing you away. And this is what Derek taught you, to stand up for yourself. It’s not that you believed Derek would take advantage of you; you just needed some confirmation that this was real.
“I know that,” Derek approached you again. You promptly straightened out your back, trying to hold your ground.
But your voice betrayed you, folding under the weight of your next question, “Then, why did you kiss me?”
“Because I don’t care anymore. I can’t keep pretending there’s nothing here,” he confessed, reaching up to tuck a loose strand of hair behind your ear, delicately caressing your forehead in his path. You leaned into his palm.
“Oh… wait, then, what are you saying?”
“I mean… I don’t know. It wasn’t always like this. I mean, don’t get me wrong, I always knew you were strong, I knew it the moment I found you. Then one day, something changed. You changed. You weren’t that same girl anymore. All of a sudden, you became this intelligent, self-possessed, beautiful young woman. And I couldn’t just keep patting your head and pretending things were still normal between us.”
You bit your lip and looked down.
“So, it’s not just me, then? You felt it too?” you asked shyly, too afraid to look at him.
Derek nudged your chin upwards with his knuckle, using his thumb to stroke your jaw.
“Definitely.” He granted you a small smirk, his eyes twinkling.
That was all the confirmation you needed as you charged forward to press your lips against his and snaked your arms around his waist, pulling him flush against you. Derek responded immediately by fisting your hair and cupping your jaw, enveloping you into his warm embrace.
You felt around for the hem of his shirt, lifting the edge of the material. Derek pulled away as you raised it over his head and threw it aside. You panted while you took him in, admiring the smattering of dark chest hair that decorated the hard planes of his chest. The rest of him was smooth, aside from a treasure trail that disappeared behind his jeans.
In a surge of confidence, you decided you wanted him to see you too. You stepped back and lifted your tank top over your head, leaving you only in a red bra.
You heard Derek inhale a sharp breath. You were slightly disappointed when he maintained eye contact with you, the veins in his neck straining against his skin, like he was still trying to be respectful.
You walked towards him and grabbed his wrist, guiding his palm between the valley of your breasts. You eyelids fluttered shut as Derek’s hand slowly drifted down your torso, fingertips grazing the sensitive skin just below your belly button.
“I’ve wanted this for so long,” you admitted airily. “I finally have you.”
“God, you’re so beautiful.” Derek’s said, voice gruff with earnestness. No one had every spoken to you this way.
You felt your chest flush as you scoffed, whispering, “Not as beautiful as you.”
When you opened your eyes, Derek was looking at you somberly. He reached forward and brushed your hair away from your face and kissed you tenderly, much softer than before. You were pliant against him, curving and arching into him every time he moved. Your hands found his hips, squeezing the defined flesh before you started to unbuckle his belt.
You palmed Derek over his boxers, his hips bucking involuntarily into your hand as he groaned into your mouth. Pulling away, you trailed your mouth over his jaw and neck, sponging open mouthed kisses down his chest and abdomen until you were on your knees, eye-level with his erection.
“[y/n], you don’t have to,” Derek protested. He palmed your jaw upwards to look at you. You grinned up at him.
“I know,” you said, slowly stroking him. “I’ve just always wanted to know what it’s like to suck off Derek Hale.”
You gave no warning before you took the head of his shaft fully into your mouth. You watched Derek throw his head back and hiss.
“Fuck, [y/n],” Derek cursed. He reached down and placed a comforting hand on the back of your head, his fingers combing through your hair.
Any sort of encouragement was highly appreciated at this point, because even looking at Derek’s cock was intimidating. You weren’t exactly surprised by his considerable size, especially since his bulge always gave him away. But nothing you’d imagined could’ve prepared you for the real thing.
Noticing the prominent vein underneath his shaft, you lifted his cock vertically. You satisfied your urge to kiss him along the feature, trailing your mouth up to his tip.
“What are you doing? Are you… fuck, that’s so hot,” Derek complimented, his tone gravelly. You smirked, looking up at him through your lashes.
“You’re too pretty not to kiss,” you teased, but it was completely true. You licked a stripe up his shaft. Taking a deep breath, you stretched your mouth open as far as you could, taking in all of him. Or really, as much as possible, which was about half. You pumped the remaining portion, palm twisting up and down.
“Oh my god, [y/n], where the fuck did you learn to do that?”
You giggled. “What, this?”
Gripping Derek’s thighs to anchor you forward, you bobbed your head back and forth, sucking him off while you continued to stroke him.
Derek’s responded with a fist tangling in your hair, guiding your head against him.
It was turning you on so much that you were affecting Derek that you slipped a hand into your shorts, rubbing yourself over your underwear.
You reminded yourself to breathe through your nose while Derek filled you. Derek Hale was inside of you and nothing else could ever be this important.
You couldn’t help but moan against Derek’s cock as you pleasured yourself, using your other hand to fondle his balls. Profanities tumbled incoherently from his lips as your moans vibrated against him.
You stopped suddenly when you felt him tug your hair backwards. Derek fell out of your mouth with a little pop! as you pulled away. Derek grasped your shoulders and pulled you up to stand.
“If you keep doing that, I’m not gonna be able to hold back,” Derek warned, pressing his forehead against yours. He affectionately stroked your cheek with him thumb.
You felt giddy, beaming with delight and a twinge of pride.
“Who says I want you to hold back?”
You could’ve sworn you saw Derek’s eyes flash red.
“Trust me, sweetheart. I could make you regret those words.” Derek’s voice was rough and scratchy, the tone sending shivers up your spine.
“You sure about that? Let’s find out,” you challenged, the thought of Derek dominating you jolting your senses.
Derek softly chuckled. “Let’s save that for next time.”
Next time. Derek wanted a next time.
“Right now, I want you to undress.”
Your mouth went dry at his command. There was that authority you loved so much.
Hooking your thumbs into your waistband, you bent over and slid the material down your legs, stepping out of them. You were now clad only in a pair of black panties and a red bra. You passively regretted your choice to forego matching underwear.
But Derek didn’t seem to mind as he blatantly stared at your legs, giving you a once over. He walked towards you, staring directly into your eyes.
You whimpered when Derek’s thumb pressed to your bottom lip, folding the flesh under, the gesture prompting you to part your mouth.
“So beautiful,” he whispered. He leaned forward to kiss you, slowly and softly. This was a sharp contrast to the way he suddenly swooped down, still attached to your mouth. You yelped at his sudden movements, arms wrapping intuitively around his neck. He grabbed the back of your thighs to lift you up into his arms.
He held you to him as he started walking, an arm locked around your waist, the other grasping your neck to keep you in place. You were ridiculously turned on that he could carry you so effortlessly.
Derek descended and you felt your knees touch the mattress. He sat down with you in his lap. You continued exploring his mouth, your hands trailing his back. You scorched his shoulder blades with scratches you knew would heal seconds later.
Your actions elicited a grunt from Derek, who was also engrossed with your back. You felt the rough pads of his calloused fingertips knead forcefully, his aggression causing you to arch away in bliss. With a tweak of his fingers, you felt him undo your bra.
You broke away, observing Derek while you nervously slid your bra straps down your arms, your hands shaking. Derek’s tongue flicked out against his lips as he admired you, his immediate reaction easing your worries. He wasted no time, littering kisses down your chest, palming your breasts. You threw your head back and moaned.
“You’re so perfect, sweetheart,” Derek rasped as he nuzzled your neck. You felt over-stimulated with Derek rubbing you and kissing you simultaneously. Needing to relieve tension, you involuntarily started grinding on Derek’s lap, pressing your panty-covered sex over Derek’s thick erection.
You moved together, Derek guiding you back and forth with his hands on your ass and lips on your collarbone. You clung to his broad shoulders for support.
When Derek suddenly bit down on the juncture between your neck and shoulder, you gasped in pain and surprise. You were already healing. The gesture actually felt intimate and romantic instead of violent, a throwback to the first bite Derek ever gave you. Even now, when you were tangled in his limbs, he seemed afraid that you would slip away.
“Mine,” he whispered into your neck.
He was trying to mark you.
“All yours, always been,” you promised.
You burrowed your face into his neck, returning his affection by lapping at his skin, not feeling brave enough to bite your Alpha.
“Please, Derek,” you pleaded, trying to communicate your desire.
“Shh,” he murmured. “Don’t worry, I got you.”
Giving your ass one final squeeze, he slid his fingers into your underwear, spreading your wetness along your slit. In response, you dug your fingernails into his shoulders as you desperately rode his hand, your desire becoming frantic.
Suddenly, he pulled his hand away. You whimpered at the loss of contact, but then cried out when Derek slipped your panties to the side and entered you in one swift motion.
“Fuck!” you exclaimed as Derek filled you to the hilt. After letting you adjust, he moved slowly, holding onto your hips as he glided in and out. You felt his cock stretch your walls, clenching your thighs every time his tip grazed your g-spot. Derek was everywhere, around you and inside you.
His hands were restless, alternating between gripping your hips and tugging at your hair. His teeth grazing against your nipple left you a squirming mess above him. You cradled his face and leaned forward to kiss him. Arching your back, you gave your hips leeway to meet Derek’s movements.
“That’s it, baby. Ride me,” Derek urged.
His command rang in your ears. It thrilled you that Derek was giving you control.
You braced some of your weight on your knees, ascending from Derek’s lap. Using his shoulder’s for leverage, you raised yourself just until you reached his tip, then slammed your hips back down. You picked up your pace, trying to match Derek’s earlier momentum.
“Is this how you want me?”
Derek growled his approval.
His encouragement made you feel sexy and wanted even in your fervid state. You could hear the distinct slap of your ass against Derek’s thighs reverberate through the expanse of your bedroom. The assault from Derek’s mouth left your chest decorated with red bruises. Your breasts bounced in rhythm with your exertions.
One of Derek’s hands gripped the flesh of your ass. The other reached behind you to clamp down on your shoulder, helping you descend down his enlarged shaft.
“Are you close to coming?” he asked. He reasoned with you so calmly that you were actually embarrassed by just how close you were. You felt a knot tighten just below your stomach and you knew you would burst soon.
You couldn’t even formulate an coherent response, resorting to just emphatically nodding your head.
He relinquished his hold, reaching down to rub your clit. His rough
fingertips fervently moved against your sensitive nub, the stimulation
breaking your rhythm. Derek took over again as he wrapped an arm around
your waist to hold up your thrashing form as he pounded into you.
You cried out as your walls contracted, your eyes screwing shut as you reached your orgasm. A few erratic pumps later, Derek was joining you at your peak. You climaxed together, him groaning into your chest while you hung on to his shoulders.
Your body shook as you came down from your high, your head hung low on Derek’s shoulder. Your body felt so numb, you couldn’t even figure out where you
ended and he began. Your sweat, breath, even skin seemed to melt
together. Derek rocked you back and forth in his lap, combing his fingers through your hair and cooing mantras of “shhh” and “I’m here, baby” into your ear.
Derek did what he always does–he took care of you.
“So,” you mumbled, finally breaking the silence. “That just happened.”
You sat up to look at Derek.
“I’m in love with you, too.”
You merely blinked at Derek’s admission, completely caught off guard. Were you still delirious from your orgasm or did Derek Hale just say he loves you?
“You heard me,” Derek quipped, avoiding your gaze, opting instead to fiddle with a strand of your hair.
“But… you know you don’t have to say that, right?” you nudged his face to look at you. “I know we just had sex, but I didn’t put out to force you into saying ‘I love you’ back. Like I said, I don’t even know for sure if I love you–”
“That’s fine,” Derek interrupted you, cracking a smile. “Really, it’s okay. I still love you. And you can say it back when you’re ready. I can wait for that.”
“Really?” you asked shyly.
“Of course,” he rolled your eyes, his attitude evoking a giggle from you.
“Aww, what a sweet Alpha,” you playfully taunted as you ruffled his hair.
Derek immediately stiffened, his hand lashing to grab your wrist mid-ruffle.
“You know what? I take it back,” Derek heckled, smirking. “I don’t love you.”
Your jaw dropped at his quip. You were sitting in Derek Hale’s lap, naked, while he made flirty banter. You faced murderous supernatural creatures on a daily basis and this was the most bizarre moment of your life.
“Is that so?” You squinted your eyes at him. “Well then, I’ll just have to find myself new man. Actually, I think Scott just came home, and since he’s the true Alpha–”
Derek suddenly grabbed the back of your neck and pulled you forward, pressing his lips to yours in an impassioned kiss. You smiled against his mouth, slightly entertained by his possessive nature. Even though your favorite werewolf couldn’t take a joke, you wouldn’t change a thing.
Derek Hale was finally yours.
