An Accountant And An Omega

Summary:

Stiles is about to start college when a rabid alpha tries to eat him and Peter saves him. When Peter realises that Stiles is becoming an omega he sees a perfect opportunity to keep him safe and provide him with an alpha, he's a charitable sort. If that alpha happens to be his nephew who would surely be much more bearable with an omega keeping him happy, well that's just a merry coincidence.

Stiles isn't too pleased to be locked in Peter's apartment waiting for this mysterious alpha to arrive. Even less happy when Peter strings him from the ceiling, aiming for Stiles to be "presentable" for the alpha.

When said alpha turns out to be scorching hot with a dick that deserves to have sonnets written about it though he might not mind so much.

Notes:

So I'm off sick from work and on a porn writing spree!

Used to read this fandom a lot back in the day but not sure how popular it is these days? Oh well if it's not I wanted to write this anyway.

Tagged mild dubcon cause Stiles is in heat and Peter does technically abduct him (but it's not played super serious like) but Stiles 1000% wants to get fucked by Derek and initiates it (and is totally clear headed after the first time).

Not beta'd and I hit a wall after a bit editing it. It seems to be in a decent state but I'm sure something slipped though. Feel free to point out any egregious errors and I'll fix em!

Thanks for reading!!!

(also forgive the title I just had no idea what to name this)

Work Text:

As he hung suspended from the ceiling, rock hard and desperate, Stiles reflected on how he ended up in this predicament.

When he'd been bitten by a rogue alpha, the wild eyed lunatic practically taking his arm off in the process, he’d thought that was as bad as his year would get. Two days later he’d had the startling realisation getting mauled was a warm up when instead of developing super strength and becoming a befurred superhero in the making he was bluntly informed he was developing into an omega . He got a little stronger sure and he started healing a bit quicker but those benefits paled in comparison to a beta and came with the low, low price of a fate as some asshole alphas personal toy. He’d refused to believe it at first — he should be starting college not becoming a halloween monster — but as the weeks past and he became hornier and hornier, feeling an inexplicable desire to find a powerful alpha and submit he realised he was fucked.

That’s how he had ended up at Peter Hale's apartment asking for help. He had been the one to save him from the lunatic and the only wolf he knew. Unfortunately the guy was unbearable. Stiles suspected he was physically incapable of speaking a plain sentence. He seemed to have truly convinced himself he was some kind of story book villain; complete with arch monologues and grins that tried desperately to be enigmatic. The man should be studied.

Still, beggars can’t be choosers and so he was saddled with the guy.

As unhinged as he seemed, Stiles really hadn’t expected him to stop him leaving. He’d wasted no time painting himself as some kind of hero all the while abducting him. He told him that walking about outside, any unmated alpha would launch themselves at him if Stiles didn’t do it first. He’d told him that binding to an alpha was an inevitability but Stiles could at least bond to a decent one. That's when he’d tried to sell him on his nephew and his description had certainly painted a picture: Broody, ill tempered, communicated mostly in growls. Truly, the full package but at least he’d been assured that this guy, Derek , wouldn’t hurt him and at this point what choice did he have. He just had to get through a few weeks for Derek to arrive. Not like he had much of a choice with Peter making it his mission in life to prevent him from leaving.

As shit as the situation was, Peter fed him and didn’t touch him. He pretty much just let him do his own thing, so long as his own thing wasn’t leaving the apartment. As time wore on and he felt that need for an alpha grow he started to see some sliver of logic in it. He realised that as hard as it was to admit Peter was, at least to an extent, right. He would have thrown himself at any alpha and he didn’t want to be mated — a lifelong arrangement he discovered — to some abusive asshole. He could only thank God that Peter wasn’t an alpha, that would truly be a fate worse than death, and pray his nephew didn’t take after him too much.

It had started to seem like a thoroughly shit but ultimately uncharacteristically generous deal. Then came that morning when Peter had kindly informed him that his nephew would be arriving and for the sake of there being any chance of success in whatever scheme he’d gotten pulled into he needed to be “well presented”.

Cue him trussing Stiles up naked like a thanksgiving turkey with complex ropework. He left him suspended from the ceiling above the bed, a spider web of ropes supporting his body facedown with his knees bent towards his ass. He’d completed the picture with blindfold and gag. He seethed as he hung there, helpless, horny as fuck and planning the day he would see how far Peter’s bullshit beta regeneration really went.

 

***

 

Everything changed though when he started hearing voices from the living room. Two voices. Peter’s obnoxious one he recognised right away but the other one . It was deep, gruff, masculine and made Stiles’s cock ache. Something about it made him struggle against his bindings, desperate to get closer to whoever made that wonderful noise. Stiles couldn’t make out the words, even when the hot one — Stiles just knew he had to be hot to make those sounds — raised his voice in a shout. Eventually he heard the front door open and close and then silence for several minutes. Stiles feared the hot one had left, leaving him alone with Peter , but his worries were assuaged when the door to his room opened . Stiles couldn’t help the loud moan that passed his gag, or the shudder that wracked his body as the scent hit him. Alpha . He knew it instantly. The alpha would make him feel better.

Fuck ” he heard from by the door in a broken voice. Stiles was right, it was definitely the hot guy.

Stiles wanted to scream at him as he just stood there for several seconds. Weren’t omegas in heat supposed to be nearly irresistible to unmated alphas? And instinct told him this one was unmated. Yet he didn’t touch him for what felt like hours.

Finally the door closed and the alpha walked slowly towards him. “He fucking suspended you?” the guy said but he sounded a little out of it. A tentative hand landed on his thigh and Stiles moaned loudly. Jesus it felt good. His hand was large, warm, calloused and Stiles wanted it to move all over him. “God. You're a needy little thing aren’t you” the alpha said. His hand became less tentative as it moved over his ass, up his back and to the back of his head before pulling away. Stiles whimpered at the loss. “I didn't know he did this, you know” the alpha said “he's wanted me to take an omega for years but I didn't think he’d go this far”.

At that moment Stiles couldn"t really find it in himself to care about creepy asshole uncle hanging him from the ceiling. He just needed to find out if this Alpha was as hot as he sounded and get his dick in him. He moaned through the gag and thrust his hips as much as he could with all the rope to try to get his point across.

“Fuck, your perfect though” the alpha said, desire lacing his voice. There was another pause and some deep breathing before he began to walk away again and Stiles whimpered. “I'm just gonna let you down” he said and Stiles felt himself lowering until he was pressed against the bed. He wasted no time rutting down against it and moaning pitifully.

He could hear the alpha’s laboured breathing and his arousal was clear in his scent but he sounded like he was trying to keep control “I’m just gonna get all that off you and then we can talk”. He pulled the blindfold off and it took Stiles eyes a second to adjust to the low light in the room before he saw him. Fuck he thought, definitely hot . He was tall, older and looked a little wild. He had dark hair and a sharp, stubbled jaw line. He wore a black t-shirt that clung to his muscles and black jeans that hugged him sinfully. He could see chest hair peeking slightly over the neckline of his shirt. His scent was deep and woodsy. He oozed masculinity and dominance and Stiles wanted nothing more than to submit to him. He removed the gag next and Stiles wasted no time begging. “Please, please alpha fuck me. I need it. Give me your knot. Please ” he begged, continuing to rut into the bed.

The alpha’s jaw clenched and he seemed to force control over himself, “I’m gonna take these ropes off you but when I do you need to stay on the bed”. “Please alpha just - “ “you will stay on the bed and behave yourself” the alpha told him, his voice pitching deeper and eyes flashing red. Despite his desperate need for him Stiles' body went limp, a need to follow the alphas' command swallowing him.

“Fuck” the alpha breathed out. “Haven't even bit you and you're following my commands so well” he said, shaking his head in amazement.

Apart from the frantic grinding he couldn’t stop, Stiles stayed still as the alpha untied him until he lay prone on the bed unbound. The alpha lowered to a crouch down by his head and Stiles bared his neck instinctively.

He closed his eyes to collect himself for a second before looking back to the desperate omega. “I"m not going to rape you. My uncle planned to give you to me but I’m not going to take an unwilling omega” he told him and Stiles whined.

“I’m pretty fucking far from unwilling dude, look at me. What's wrong with me that you'd say no?”

“Nothing babe” he stroked the side of his head and Stiles leaned into it. “You're perfect but I can’t be that guy”.

“So what? I"m supposed to just stay like this?” he asked softly “Find some other alpha to fuck me?”

At that, Derek"s nostrils flared. He gripped his head tightly and his eyes flashed red again, he could see a hint of fang in his mouth. The wave of submission that went through Stiles was unbelievable before the alpha closed his eyes and breathed deeply again, when he opened them his eyes were back to pale hazel.

“Don"t talk like that. My instincts-”

Stiles could tell his own instincts were overwhelming him and if he had to use that to get this beautiful man to fuck him and give him some relief, at that point, so be it.

“I’ll go out of here and kneel for some other alpha. I’ll let them do whatever they want to me. I’ll beg and plead for their knot. I’ll bare my neck for their bite.” He told the alpha. He knew he was being underhanded but at this point he couldn’t care. He needed this alpha to fuck him and he could smell he wanted to.

Suddenly the hand on his head grabbed his hair and pulled him up harshly. “Don’t fucking push me boy” he told him but it did the opposite of scare Stiles off. He looked him in the eye “please alpha I’ll do anything. I’ll be so good. Please. I need it” he whimpered.

The alpha leaned down to the crook of his neck and inhaled his scent. Stiles could feel his stubble tickling against his skin and he whined as he bared his throat.

“What's your name”

“I-”

“Your name, boy. What is it” His voice took on that deeper quality again.

“Stiles” he said breathily

“Derek” the alpha — Derek — said.

“I’ll fuck you Stiles” he said and Stiles could have cried with relief. “I’ll fuck you and I’ll knot you but I’m not fucking biting you. We’ll go to mine after this and we’ll talk through everything while you can think clearly. Understood?”

“Oh god please Derek”

Stiles' hair was pulled sharply and he leaned into the flash of pain.

“Am I fucking understood Stiles? I’m not gonna be able to hold back for much longer with you like this”

“Yes. Yes. Please just fuck me”

“Stay on that fucking bed boy” he told him as he pulled away

Stiles could only watch, entranced, as the alpha pulled off his clothes. He clearly wasn’t trying to put on a show, just get them off as quickly as possible but it couldn’t help but be one with the way he looked. Stiles drank in his body. He was lean and muscular with dark chest hair tapering down to a tempting trail. As he looked at him he could’t help but think if being an omega means getting fucked by all of that maybe it wouldn’t be so bad after all.

He unbuttoned his jeans and shoved them down his sharply defined hips which revealed his cock. He was rock hard and Stiles couldn't help but swallow at the size of him. He wasn’t a virgin but he’d only been with one guy a couple of times and he'd been squarely average. Derek was anything but. The only word that could describe him was huge .

Stiles could see that a portion of his shaft at the bottom was a lighter colour although it otherwise looked like the rest. Stiles knew though, that would swell when he knotted him and he couldn"t help the apprehension that cut through him. He had a hard time imagining his cock fitting without it. He couldn’t imagine how he'd take it when he swelled up.

Derek noticed him staring, “having second thoughts boy?”.

“Your fucking huge dude” he told him bluntly.

Derek closed his eyes and breathed heavily “If you don't want to do this run now. I`m not gonna be able to stop myself in a second Stiles. Run now or I’m fucking you into that bed no matter what you say”

Stiles couldn’t help his whimper at the statement.

“No. No, I want it. I'll take it.” Derek`s eyes opened and Stiles looked straight at him “Make me take it alpha” he told him and knew that was it.

Derek climbed onto the bed, pushed his head down with his hand and lowered his head to his neck again. He took another deep inhale of his scent before growling — a sound that had no right to be as hot as it was. His body felt red hot against him and Stiles groaned as he pushed his hips against him, grinding the length of his cock into the seam of his ass.

“Is this what you want, boy?”

“Fuck. Yes. Please” Stiles gasped out. Already overwhelmed.

“Keep lying there like a good boy and I"ll get you ready for it”

Stiles wanted him to just put it in but clung to some shred of reason — he’d rip him in half without preparing him, maybe even with it.

Derek lubed up his fingers — he'd gotten a tube from the nightstand — and began circling his hole with one as he licked and nibbled at his neck. Stiles arched into it desperately begging him to just push in. Derek refused to rush it though.

He took his time circling before slowly pushing one finger in and enjoying Stiles' gasp. At his pleading encouragement he rapidly added a second and third before hooking them to rub right against his prostate.

Stiles keened as he pushed against the fingers. They’d gone to three so fast it burned but he needed it and the feel of him rubbing against his prostate had him gasping out Derek’s name.

It felt so good but it wasn’t what he needed, “Please Derek just fuck me. God, please I need it”.

“You're not ready yet boy” he grit out as he began scissoring his fingers inside the pliant omega.

“I can't take it” he whined, sounding broken. “Derek I need it”.

“Soon boy” he reassured him as he began thrusting his fingers.

“Fuck your so tight” he told him, grinding harder against his ass. His own need to fuck him becoming hard to manage.

“Alpha please I-”

He broke off in a hiss as blunt human teeth hit down hard into the crook of his neck and he heard and felt a low growl against his skin.

A fourth finger entered him without warning. His fingers were longer and thicker than his own and he already felt so full. All he could think about though was it wasn"t enough. He needed more.

Derek"s teeth disengaged from his neck, "you’re not ready enough but this is as good as I can do. I can"t fucking hold back with you like this".

"God don't hold back please. I want it all"

Derek kept a firm hold of the back of his head keeping him pinned to the mattress as he reared back. Suddenly, Stiles could feel something hot and thick at his entrance. He arched into it as much as his position allowed.

He whined high in his throat and gripped desperately at the bed as the head pushed in. It stung, he was so thick. So much thicker than his fingers. Still he arched into it, he wanted more.

As he began pushing in he went slow, inch by inch. Stiles gasped through the overwhelming stretch till he felt like he could take no more.

He clawed at the bedding, "oh god I can"t. Wait. It's too much".

Derek lowered himself back down and put an arm across the bed beneath his neck, balancing his weight. Stiles promptly sank his nails into it, desperate trying to ground himself through the overwhelming sensation.

"You can take it boy, you will take it. You feel so good."

Derek continued pushing in and Stiles moaned and shuddered as it put pressure on his prostate — adding pleasure to the sharp burn.

"You wanna be good for your alpha don’t you boy?" Derek asked, sounding breathless. Stiles could feel him sweating where he lay over his back.

His heart sang at this man calling himself his alpha. "Oh god I want to. I wanna be good for you".

"Then just breath, I’m gonna give you the rest"

Stiles tried to brace himself but Derek wasted no time. He pushed forward with a single, sharp snap of his hips until he was all the way in.

Stiles wailed and bit the arm beneath him trying to withstand it. He felt like he'd been ripped in half. Yet still pleasure broke through the pain. Over it all though was an overwhelming feeling of possession and he sank into it.

"Oh god, oh god. You're so deep. Fuck ".

"I can give you a few seconds boy but then I"m really gonna fuck you" Derek panted into his neck.

Tears welled in Stiles' eyes as Derek ground his hips against him. He continued to cling to Derek’s arm, his one point of stability in the overload of sensation, as he tried to adjust to the massive cock impaling him.

He whined as Derek started to pull out, "I can't hold back now boy" he panted as he snapped his hips back into him.

He rapidly developed a punishing rhythm. All Stiles could do was wail as tears leaked from his eyes and endure it. He didn"t even know how to describe the sensation anymore, it was almost beyond pleasurable. So overwhelming he could hardly process it.

It only took a couple of minutes until he was cumming between his stomach and the bed without either of them stroking his cock. Derek growled roughly into his neck where he was biting and sucking bruises as he felt him clenching through it.

"God, you're perfect. Taking me so well. Such a good boy"

Stiles had never considered himself to have a praise kink but something about being good for this alpha made him hot.

Suddenly Derek pulled out his cock without warning and flipped him over roughly before shoving back in.

Stiles raked his nails down his back at the rough treatment, "wanna see your face when I knot you boy. Wanna watch you fucking break".

All Stiles could do was wail as he clenched his shaking thighs around Derek’s back. His cock was already hard again and leaking precum against his stomach.

Derek reached down and wrapped a hand around his length and started stripping it rapidly.

Stiles reached to his wrist to desperately try to push him away. He was too sensitive, he couldn’t come again so soon. His hand froze though when Derek’s eyes flashed red again, "keep your hands on my fucking back boy". Stiles complied, unable to deny his alphas command.

He tried to move his hips to ease the overstimulation but only succeeded in pushing into Derek’s hammering cock. He couldn’t escape.

"I can't Derek. I can’t".

" Yes you can, boy. You want my knot don't you?"

"Yes alpha please"

"You want to be a good boy don’t you?"

"Yes,yes,yes,yes"

"Then prove it", his eyes were a dull burning red now. Not the fire of when he ordered him but he was obviously losing control himself. "Cum for me. Show me what a good boy you are for me"

Stiles yelled as he shot over both of their stomachs. Derek’s thrusts didn’t slow as he reached his hand up and licked the cum off his fingers. The look of dominant satisfaction on his face had his overworked cock twitching on his stomach.

Derek leaned back down to his neck and spoke to him between kisses. "I’m gonna fucking knot you boy. I’m close." He groaned into his ear. "It's gonna be a lot boy, but you can take it. You're doing so good".

Stiles held Derek’s head to him with one hand as he broke off in a deep groan and his thrusts stuttered. He reached down with the other to feel his firm ass twitching as he filled him up. He gloried in the pleasure his alpha was finding in him.

That's when he felt the pressure. A dull ache spread through his ass as the pressure intensified every second. As Derek thrust into him, more irregular but just as hard, he could feel the forming knot catching on his rim. He turned his head into Derek's sweaty neck and wailed. His overstimulated body felt like it was never going to recover from this.

Finally Derek’s thrusts stopped and he pushed hard into him as his knot locked him inside. His moans were filthy as he shook on top of him, caught in a continuous orgasm as he filled him with his cum. It was so unbelievably hot but the pressure just kept building. Stiles could hardly think as he clawed at his back, his ass, desperately trying to withstand it. He felt like he was being ripped open but at the same time the knot pressed so hard against his prostate. Each wave of pleasure that crashed through him caused him to clench which only increased that pressure and caught him in a brutal cycle.

"Oh god Derek. Derek"

Derek gathered himself to pull up and look down at him. He took in the ruined expression on Stiles’s face, the desperate noises he was making, the tears on his cheeks. Derek didn’t look far off with wild eyes and sweat pouring off him.

"Your fucking perfect boy" he told him. "I want you to cum around my knot"

Then he started grinding his hips. Stiles could feel the knot pull against his rim with each small aborted thrust he made and rub hard against his prostate. It added a whole new dimension to the brutal stimulation.

He sank his nails into his shoulders, "I can't. I can’t. I can't"

" Yes you can, boy. Your gonna cum just from my knot" Derek panted at him as he went back to groaning into his neck.

Derek didn’t touch his dick, all he got was the small amount of friction from his abs pressing against him as the grinding continued.

It took twenty minutes before Stiles felt like he might cum. He’d begged to touch his cock but Derek was dead set on him cumming from his knot. Stiles pleaded that he couldn’t, yet in the end he did.

He shook and keened as he spilled yet again between their bodies. Every time he clenched around the huge knot Derek let out a broken groan as he panted praise into his ear. Stiles felt like he’d never be the same as he clung to the body that was wrecking him and tears ran freely from his eyes.

Derek continued to grind into his abused prostate as Stiles clung to him and steadily the knot went down. Eventually he pulled out and Stiles shuddered before Derek quickly got a cloth from the bathroom and cleaned him up.

He praised Stiles the whole time. Told him how well he did, what a good boy he was for him.

Stiles just continued to lay there feeling like his whole word had been rearranged along with his internal organs.

Finally Derek pulled on his clothes and prompted Stiles to do the same.

He was unsteady as he pulled on sweatpants and a graphic tee before sitting on the edge of the bed.

"Where are we going?" He asked Derek, slightly dazed.

"I live twenty minutes away, we’ll drive there and then we can figure out … this".

"You live twenty minutes away but you took weeks to get here?"

"I was in the U.K for work"

"Doing what?"

"I'm an accountant"

Stiles couldn’t help the chuckle that escaped him. "An accountant? An alpha werewolf accountant?". All the tension drained out of him as he rolled in the bed shaking with hysterical laughter.

"It's not funny" Derek said sounding defensive

"No, I'm sorry, just …" he started laughing again.

Derek grabbed an old hoodie off the back of the chair and threw it at his face. "The first heat hits in waves. We need to get going before you feel it again. I want to talk while you can still think clearly" he told him gruffly before going into the living room.

Grumpy indeed Stiles thought as he went in to join him, still chuckling.

This guy might really not be so bad he thought. I certainly wouldn't mind sex like what we just had for the rest of my life he pondered as he looked at him speculatively.

Derek noticed it and asked what he was thinking about.

"I was thinking I wasn’t too happy to turn into an omega and get abducted by your lunatic uncle" he said bluntly.

Derek looked a little flustered. "Yeah I"m sorry about Peter, he’s… I don't really know. Not well."

After the turn things had taken Stiles found it hard to actually be mad at Peter, "eh he's mental but he wasn’t that bad to me until he hung me from the ceiling”.

Derek looked uncomfortable at the reminder of how he’d found him and a slight blush touched his cheeks. It was surreal to see this man who had just fucked him better than he could have imagined was possible, looking a little shy.

“I was also thinking your crazy hot, that sex was incredible and maybe being fucked by you on the regular wouldn’t be so bad” Stiles threw out impulsively.

He watched Derek’s blush deepen and he swallowed as a hint of red returned to his eyes.

“You don’t regret it?” He asked Stiles, sounding a little unsure of himself.

“Why would I regret it? I’ll regret you not doing it again though” he said, a cheeky grin touching his lips.

“We…we need to get back to mine” Derek decided, taking Stiles’s hand and pulling him out of the apartment.

They went downstairs and got into a black camaro sitting outside.

 

***

 

“Nice car”

“Thank you” Derek said as he started the ignition and pulled out.

As they slowly drove towards town, to wherever the hell Derek lived, the tension in the car was palpable. Stiles couldn’t stop looking at him and Derek seemed a little uncomfortable with it.

“Between these waves of heat or whatever you're not driven nuts by my scent right?”

“No. I can control myself fine right now”

“Ok, cool. So like, objectively, without my scent, am I still someone you’d fuck normally?” Stiles asked, genuinely curious. He knew he was kinda cute in a gangly sort of way but Derek was straight up top tier hot .

“Yes” Derek said with a hint of a growl in his voice.

With such a blunt confirmation Stiles felt some renewed confidence.

“Can I suck your dick?” He asked Derek.

“What?” Derek looked a little startled by the question.

“It’s a yes or no question dude. You say you're into me and I want to suck your dick. I mean why not right?” Stiles said simply.

The steering wheel creaked as Derek tightened his hand on it and his breathing deepened.

“You shouldn't be feeling your heat yet” the slight, sexy growl had returned to his voice.

“I’m not, I-” he decided to be a little vulnerable “Look your super hot and that sex was incredible. I might not be feeling my heat right now but surely you can smell how turned on I am. I wanna suck your cock and find out what your cum tastes like dude”.

Derek was borderline panting now with a slight flush on his neck and cheeks.

“I- Ok” he said finally giving in and Stiles didn’t hesitate.

He leaned over the central console and unbuttoned his jeans to pull out his already hard cock. He was able to properly admire it this time, and it deserved to be admired. “God your so fucking big dude. So thick” he said as he leaned down and circled his tongue around the head.

Derek shifted his hips forward slightly into him and his breathing stuttered. The steering wheel creaked again from his grip. “I- thanks” he said, still sounding unsure. It was so strange but kind of hot, this combination of shyness and the dominance he knew he was capable of. He wondered how long it would take till he took control.

Stiles had sucked dick before but not much and nothing this big. He knew he wasn’t going to be able to take it all but he was certainly eager to see how much he could manage. He wrapped his lips around his teeth and went down until he could feel him pressing against his throat. Doing his best to relax, he went deeper and heard Derek groan as his throat wrapped around him. He kept pushing even when he started to choke before he was forced to come up for a breath.

Pulling off he returned to his side of the car to quickly shove down his sweatpants and grab his hard cock, stroking himself with one hand as he leaned over and took Derek into his throat again.

“Fuck, you like sucking my dick that much?” Derek asked, heat in his voice. He wasn’t sounding so shy now.

Stiles pulled off and stroked him with his other hand as he spoke to him, “Yes. I love it” he panted “Can you cum without knotting? You're huge already, I don't think I can take that in my mouth”.

“Yeah” Derek said as one hand left the wheel and grabbed his head, guiding him back onto his dick.

Derek pushed him even deeper and hitched his hips up into him at the same time. It made him choke more but he just rubbed his cock faster, turned on by the show of dominance.

“Jesus you fucking love it” Derek groaned out as he shoved Stiles down hard on his cock.

It didn’t take long until Stiles came, moaning desperately around Derek’s cock. Derek groaned as he felt the vibrations of it and started fucking his face even faster.

“I’m close Stiles” he told him, breathing heavily. “Swallow it all boy. Every fucking drop”

Stiles did, as Derek filled his throat with a groan. He could hear a sharp screech as Derek’s firm grip bent the steering wheel. He savoured the taste of his alpha as he sucked him through the aftershocks until he pulled off, panting.

He tucked Derek back into his jeans and then returned to his side of the car to pull up his sweatpants.

He looked from his cum across the front dash to the bent wheel in Derek’s grip, “uhhh, sorry about your car dude”.

His eyes raised to meet Derek’s and he found them burning red. He didn’t seem at all bothered about the state of his car, “When we get home I’m gonna explain things to you and you’ll have one chance to leave Stiles. If you don’t I’ll be keeping you” he told him, his gaze intense enough to make Stiles shiver.

“O-Ok” Stiles said. Gathering himself, he tried again, “I already know my answer though” he told him.

Derek looked forward again and took several deep breaths, the red in his eyes fading. “We’ll talk it through” he said simply.

 

***

 

Stiles whisted as they walked through into Derek’s apartment. He lived on the outskirts of town in a large but mostly nondescript building. His apartment was huge though, he clearly made good money as an accountant.

“Nice place. Like, really nice place” He said as he looked around a little. The whole place was saturated with Derek’s scent, he found it comforting.

Derek seemed to puff up with pride that Stiles liked the place but quickly directed him to the couch.

“I can smell your heat starting to build again so we need to talk now” He told him as he took a seat beside him.

“What do you want to happen tonight Stiles”

“I want you to fuck me again and bite me” He said honestly

Derek seemed taken aback by how bluntly he said it.

“Do you know what that actually means, Stiles? Me taking you as my mate?”

“It means I’d be yours forever. You’d make me scream on your knot on the regular, hopefully daily and you’d be pretty possessive”

“I’d be extremely possessive. You could still have your normal life and go to work or school though. But yeah that’s basically it in a nutshell. You seem surprisingly calm about this.” Derek told him.

“Well sorta seems like I’m gonna be bound to an alpha no matter what and you seem like a decent option so…” Stiles shrugged.

Derek looked downcast and Stiles realised he’d painted a bit of a bleak picture. He put a hand on his thigh.

“I don’t know you well obviously but so far I’m actually starting to think I got lucky getting turned. You seem really nice and kinda funny. Your super hot and seriously amazing in bed. You say you’ll let me still be independent and you clearly care about how I feel. I’m happy to be your omega Derek” He told him, voice soft.

Derek seemed touched and he could see a softness in his eyes but he still seemed hesitant.

“I just, I’m sorry I-, I should have had more control, I shouldn’t have-”

“You didn’t rape me Derek” Stiles stated, understanding what was bothering him.

“I one thousand percent wanted you to fuck me and still do dude. Do you think I’d have asked to suck your dick, and came doing it, in the car if I didn't want you?”

Realising that being forward seemed to be the way to go with Derek he straddled his thighs and kissed him. As his lips met Derek’s he realised they hadn’t actually done this yet. His lips were soft and hesitant but as he pushed his tongue in he took control. His hands landed on his hips and he grinded against him as he devoured him. By the time he pulled away they were both panting.

Stiles wiggled his hips and could feel Derek’s growing hardness beneath him. “Fuck me Derek. Knot me. Bite me. Claim me. Please” he said looking him in the eyes and watching them bleed red as he talked.

“You're sure?”

“Yes”

Derek didn’t ask again, simply picked him up and carried him to his room. He threw him on the bed and told him to take off his clothes as he did the same.

“Don’t worry I should be able to be gentler this time” Derek said as he joined him on the bed, laying his body over his.

“What on earth makes you think I want gentle?” Stiles asked as he began kissing him. “I mean I’m not opposed to gentle later but if you want to fuck me rough, fuck me rough Derek”. He arched his hips against him, rubbing himself against Derek’s now hard cock.

“I-No I don’t wanna hurt you again” Derek said but Stiles could tell from the rough tone of his voice, the glowing red of his eyes and the way he was grinding hard against him that he wanted to rail him.

“Fuck me rough Derek”

He still looked hesitant so Stiles decided to push him a little. He wanted him to really lose control.

“Maybe I should have stayed with Peter? He said if you didn’t want me there were other alphas he knew” Instantly the dull red in Derek’s eyes became burning and his hand went around his throat.

“Don’t do that Stiles I can’t stop my reaction. I told you I’m possessive”

Stiles felt a little hesitation but he was too turned on too stop.

“I bet they’d fuck me rough. I wonder if they’d fill me up better than you. I wonder what I’d look like with their bites on me” he said and saw the moment that Derek snapped.

He got right in his face “I know what your fucking doing boy. You want to push me? This is what happens when you push me” he growled before flipping him forcefully onto his stomach.

He reached over and pulled some lube out of the nightstand before covering his fingers and immediately shoving three in. Barely a second later he added the fourth.

“Oh god. Oh god” Stiles whined. It burned. He’d been stretched so much before but he’d mostly recovered from that, benefits of being an omega, so straight to four fingers was a lot.

Derek thrust them roughly before pulling them out and rubbing lube over his cock.

“Der I-” he cut off on a yell as Derek shoved his whole length in him immediately.

“You think another alpha would fill you like this?” he growled out deeply.

“No. No-” He began thrusting and Stiles wailed.

“Your fucking mine Stiles” Stiles could hear the wet thwack each time his hips hammered into his body.

“Oh god. Oh god. Oh god.” he was whimpering desperately.

“Say it boy. Fucking Say it. Who do you belong to?” Derek's pace didn’t slow at all.

“You. You. Oh god. I belong to Derek.”

“That’s fucking right”

“I want you to see” he growled and picked him up to shift his body sideways across the bed before pulling him up into a trembling line against him with his hand around his throat, claws digging in. Stiles reached back to his thigh and felt the powerful flex with each thrust.

“Look boy” Derek said and angled his head to the mirror beside the bed.

Derek’s eyes were burning red and there were fangs in his mouth. They were both already coated in a sheen of sweat and Derek seemed to tower over his smaller, lithe body.

“Oh fuck” Stiles whined seeing it. “Alpha” he moaned, seeing the absolute dominance of the man behind him.

As he looked into his eyes in the mirror, as he slammed into him so brutally, he came untouched. Derek held him in place by the firm grip on his throat as he spasmed against him, overwhelmed by how intense it was.

“That’s a good boy” he growled. “Beg for my knot” he told him.

“Oh god Derek please. Please. Please knot me” he wailed.

It formed quicker this time and Stiles shook as it locked inside him. The stretch was no less intense the second time.

“Do you want my bite boy?” he asked him, rocking his hips.

“Yes. Please”, He looked into Derek's red eyes. “Please bite me, make me yours Derek”.

Derek pulled his head to the side harshly and sank his teeth in.

Stiles shouted. It was agony, his fangs slicing through the skin of his neck like a knife through butter. Yet at the same time a euphoric feeling of complete possession and profound submission came over him. As Derek kept grinding his knot into him he took Stiles’s cock in his hand as he bit down harder. Stiles screamed as another orgasm ripped through him.

“Your mine now” Derek said darkly in his ear as he pulled his teeth out and Stiles could see the bite mark in the mirror, small rivulets of blood running down his chest from it.

Derek moved him back to his original position, pushing his head into the pillow as his thrusts intensified. The pull against his rim was intense.

“Could another alpha stretch you like this?” He growled as he pulled out harshly and Stiles could feel himself stretch around part of the knot. He screeched into the bed. He didn’t even know he could stretch that wide.

Ahhhhh - I can’t, Derek I can’t!”

“You can” he growled pulling out again

Stiles continued to scream and thrash as each thrust pulled his knot out farther until he was thrusting slowly but powerfully into him, each thrust pulling out until he was stretched around the full knot before pushing back in.

Stiles didn’t know how long he lay there being ripped apart, tears streaming from his eyes until he came again, untouched beneath him.

Finally with a contented groan Derek pushed back in and stayed there, twitching atop him.

He whispered praise into the ear of the omega, his omega as his knot slowly went down.

Stiles was ruined by the time it was done but already hoping that he’d do it to him again one day.

As Derek bundled him up in his arms and sleep crept up on him, his heat ending with the claiming, he turned to Derek and asked softly “who do I belong to Derek”. “Your mine boy, all mine” he told him and Stiles curled into him, content with his alpha.
