One Night Means Everything

Summary:

A one-night stand between Stiles and Derek results in a positive pregnancy test. As their unborn child grows, so do they, and the unexpected situation brings them closer than they ever could have imagined.

Notes:

Hi! Welcome! Just to set the scene, this is a universe with Alphas, betas, and omegas <-- and that's common knowledge, unlike werewolfiness, which is still kept on the down-low. Any other questions, just send them to my inbox!

Chapter Text

“Oh my God…” Stiles gasped against Derek’s mouth as the Alpha lifted him up against the door. Stiles wrapped his legs around Derek’s waist and moaned as more slick gushed out of him, preparing him for what was coming. And God. He wanted it. “Come on. Fuck… fuck me.”

Derek growled as he unzipped his jeans, his cock springing free, hot and leaking and desperate. He shoved the back of Stiles’ trousers and boxers down to expose his leaking hole “Yeah?”

“Yes.” Stiles met Derek’s eyes then pulled him back in for a rough kiss as Derek pushed his cock into the Omega in one thrust, the pair both yelling in relief “Yes. Yes!” Stiles gasped, his head falling back against the bathroom door.

It happened so fast. They were at Stiles’ house for a pack meeting - good food, good conversation; not much drama had been happening in Beacon Hills recently. Derek was helping Stiles clean up after the rest of the group left for the night.

Something happened between the two of them, neither of them could quite say what. It was a moment, a brush of hands – and the next minute they were kissing and grinding.

The sex was quick and rough, both desperate in a haze of endorphins; chasing their pleasure.

“Y-you gonna knot me, Alpha?” Stiles bit his lip in such a sexy way all Derek could do was bury his face in the man’s neck and nibble at the skin there.

“You would look so fucking good on my knot.” Derek whispered.

“Come on-ah!-yes!- Knot me.” Stiles gasped.

A few more powerful thrusts and Derek’s knot breeched Stiles, they both growled and shouted through their orgasms and Derek slowly lowered them to the floor, Stiles underneath him, as he pumped the man full of his cum.

“You’re… so… fucking… hot.” Derek breathed as he gripped onto Stiles’ hair.

“Mmm… you beautiful Alpha.” Stiles tried to catch his breath as he clamped down around Derek’s knot, enjoying the feeling of cum pumping into him.

They stayed like that, a mess of limbs on the floor, kissing and conjoined, for some time after.

“Have you ever fucked an omega before?” Stiles asked into the silence.

“No.”

“Ahh, so I’m your first. How exciting.” Stiles grinned.

“And what about you? Have you ever had an alpha? Or anyone?” Derek asked.

“I’ve had sex with a beta female, which was alright. But my God – after that, I swear I’m an alpha knot convert. That was amazing.” Stiles wiggled his hips a little, making them both moan.

Derek chuckled “Good to know you enjoyed yourself.”

“I’ll pick up the morning-after pill tomorrow, by the way.” Stiles rubbed his hands up Derek’s back as he nodded.

“Cool. And… uhh… this was just…” Derek worried his lip between his teeth.

“…just a good fuck? Yeah. I’m not looking for anything serious and this just… happened. So don’t worry, I won’t expect flowers and a date.” Stiles laughed.

Derek relaxed his shoulders and smiled “Good. I’m not so good at relationships.”

“Probably because your method of communication is eyebrows.”

“I’m communicating with you right now.” Derek frowned.

“Yeah and look at those eyebrows go. So expressive.” Stiles grinned then pressed a kiss to them fondly.

“Just so you know, you are fucking amazing.” Derek said after a few moments of silence.

“Really?” Stiles raised an eyebrow with a pleased smile.

“Really. For someone whose not had much experience… very sexy. I had fun.” Derek nodded and felt his knot finally deflated enough to let his cock fall out of Stiles’ hole.

“Oh wow… I can feel your cum dripping out of me.” He sighed “Now that is hot.”

Derek used two fingers to push it back in. Stiles let him but rolled his eyes and said “Such an Alpha.”

They spent the next five minutes teasing one another and exchanging sloppy kisses, but eventually they got up and pulled their clothes back on, sharing the sink to freshen up.

"Catch you later." Stiles winked as he opened the door for Derek to leave, the Alpha tweaking his bum cheek as he passed.


Stiles went to the pharmacy the following day to pick up the morning-after pill, sent Derek a picture of himself holding the packet with a cheeky wink and the caption ‘When you’re silly and don’t wrap the willy…’. He got a very ‘Derek’ emoji in response; the one with the raised eyebrow.

Stiles downed the tablet with some water and set off for school.

He had an exam today, but he’d studied for it so wasn’t too worried. Turning eighteen the month before had been a bit of a milestone for Stiles, especially living somewhere like Beacon Hills, but nearing the end of his Senior year he'd had to start thinking more about the future. He’d applied for college and was just hoping to get in somewhere with a good Psychology programme. Being a Psychiatrist wasn’t something that was obvious to Stiles, but as the years went by and the experiences he had at Beacon Hills grew, so came an insatiable desire to help more people with stories like him.

Stiles decided to definitely not tell anyone about what happened with him and Derek last night, and he knew Derek would want to keep it quiet too. It was just a one night stand; an amazing one night stand, but not one to bring to the attention of an incredibly nosy pack of werewolves. He’d had a thorough shower that morning so none of them could smell Derek on him, it had taken quite a while because even as a human Omega Stiles could smell him. Derek’s position as not only an Alpha but a werewolf made his scent very… potent.

“You see Derek today?” Scott asked as they sat down for lunch outside.

Stiles tried not to let anything show on his face “No, why?”

“You just smell a bit like him. I wanted to talk to him about getting some more literature from his family vaults.” Scott shrugged, and Stiles breathed a sigh of relief that his best friend wasn’t more curious. Though, in fairness, it wasn’t abnormal to see Derek these days because the pack was much more unified; regular pack meetings and hang outs were quite common.

“Send him a text, he’ll probably be happy to share.”

“I dunno, I always feel awkward when it comes to his family.” Scott grimaced.

“Want me to text him?”

“That’d be great, man!”

“No worries – I’ll do it in a bit, alright?” Stiles squeezed his shoulder with a smile.


Things went back to normal between Stiles and Derek, and they were relieved that there was no residual awkwardness. They still bickered and joked during pack meetings, and Stiles was still the same old over-the-top guy to Derek’s understated style in their friendship. But hey, it worked.

It was just over a month after their fling that Sheriff Stilinski found his son hunched over the toilet bowl at five in the morning.

“Jeez, son, are you alright?” Noah got a cold flannel and lay it on the back of Stiles’ neck with a soft rub of his back as the boy heaved.

“I don’t feel so good, Dad.” Stiles sniffled through his streaming nose.

“You don’t look too good either. Did you eat something bad?”

“Probably. Had take-out last night.” Stiles heaved again and Noah grimaced at the sound of vomit hitting the bowl.


Three days later, Noah had had enough.

“Stiles, I’m taking you to see a Doctor.” He announced as he watched his son hug the toilet bowl at five o’clock sharp, it was now a daily occurrence.

“Dad…” Stiles whimpered.

“What is it?” Noah knelt beside him with a concerned frown, Stiles sounded so unsure and nervous.

“Dad, I think… I have a horrible feeling I know what this is.”

Tears ran down his son’s cheeks and Noah took a breath “What is it? Some sort of… supernatural thing? Pixies?”

“No, no, not pixies…” Stiles shook his head then stopped when a wave of nausea hit. He took a deep breath, then another, then he looked into his Dad’s eyes and said "Please don't be mad. Please... please just don't be mad."

Seeing Stiles so distraught and panicked, Noah put a hand on the side of his face to calm him "Hey, kid... you can tell me. Whatever it is, I just want to help you get better, alright?" 

“I had sex with an Alpha.”

“Y-you what?” his hand dropped.

Now he'd said it, Stiles pushed on “We didn’t use condoms but I got the morning-after pill, I promise! I’m not an idiot!”

“But-but… Stiles, what about STD’s? I’ve told you to use condoms.”

“He’s a werewolf. They can’t carry STD’s.” Stiles raised his hands in surrender then moved to sit against the wall, his knees curled up against his chest “But Dad… what if… what if for some reason the pill didn’t work.” He whimpered.

Noah sighed a little shakily, then knelt in front of his son and placed his hands on his knees “Let’s not panic, alright? I’m going to get you a test, and we’ll take this one step at a time. There’s plenty of options, okay?” he pulled Stiles into a hug and said “Everything will be alright.” into his sweaty hair.

“Thanks, Dad.” Stiles wiped his eyes.

Noah left and in the silence of the room Stiles hesitantly pulled up his shirt and looked down at his flat stomach. A  thousand what-if’s and future scenarios filled his overactive imagination.


“Now?” Stiles was chewing a nail nervously.

Noah was sitting on the rim of the bathtub looking down at the pregnancy test his son had just taken. It was blank still “Stiles, it’s been half a minute. It needs about three. Just take some breaths.” Noah kept staring at the little box where he hoped two lines wouldn’t appear.

The bathroom was silent for another ten seconds before Stiles said “Now?” again.

“Mieczyslaw.” Noah frowned up at him.

“What!? Dad, I’m scared!” Stiles splayed his hands out as he paced the small bathroom.

“I know you are, kid. But whatever happens, I’m here for you, you know that, right?”

Stiles stopped pacing and looked at his Dad “I know. I… I’m just freaking out. How are you not freaking out?”

"What good would that do right now?"

Stiles shrugged and carried on pacing.

“Whatever happens, we’re Stilinskis. I’ve got your back, like you’ve got mine.” Noah said.

Stiles took a breath and nodded, they stood in quiet for a bit longer “Now?”

Noah looked down at the test and felt his stomach drop out of his feet. He handed it over to Stiles, unable to bring any words out.

Stiles looked down at the two lines and his mouth went dry. His heart raced in his ears and he felt his breath disappearing.

“Stiles. Stiles, it’s alright. Just breathe, it’s okay.” Noah helped lower him to the ground and put his head between his knees “Breathe, kid. In and out, with me.” He rubbed his back.

“Fuck.” Stiles gasped out between breaths and a few tears escaped. On the floor in front of him, the pregnancy test lay innocent and unchangeable. Stiles shut his eyes tight and hoped it would disappear.


When Stiles got his breath back, Noah wrapped him up in a blanket on the sofa. The morning sickness had worn off at this point so a glass of water and a plate of toast appeared in front of him courtesy of his father “Come on, kid. You’ve got to eat something.” Noah encouraged.

“Not hungry.” Stiles said absently. He was past shocked and panicked and was full on angry right now. Angry at the pill for not working, angry at Derek for screwing him (in every sense of the word), angry at himself for getting screwed, and mostly he was angry that he wasn’t angry at what was currently growing in his womb and making him heave every morning at 5am.

“Try to have some water then.” His Dad held out the glass and Stiles relented and took a few sips; it did make him feel a little better. More present.

“So, who is the Alpha?” Noah asked “Someone you know, I hope.”

Stiles rolled his eyes and bit out “Alphas, like Omegas, aren’t very common. Why don’t you do some digging and figure it out.”

Most of the population were Betas, almost all of the people Stiles knew were. Derek was only the second Alpha Stiles had ever met – and he’d never actually met another Omega before. Both were rare, but not rare to the point Stiles was some kind of medical marvel.

And since Werewolves came into Stiles’ life there was an even broader scope as to what exactly Alphas and Betas were. Derek was both an Alpha and an Alpha werewolf, Scott was a Beta but a True Alpha Werewolf. It was a little overcomplicated, and Stiles attributed it to the descriptions originating in werewolf packs back in ye olde times and evolving as humans and language did.

“Don’t take that tone with me, Stiles. I’d rather you tell me yourself.”

“I don’t want to!” Stiles exclaimed “I don’t want to talk about it or him.”

“Fine. But let me just get some facts straight. How far along are you?”

“Uhh…” Stiles huffed “Six weeks, give or take a day.”

“Right, so you’ve got plenty of time to explore your options.”

“Options?” Stiles frowned; he didn’t feel like he had any options right now.

“Well, you still have time to abort-“

“-What? No! No, I can’t…” Stiles stood up and the blanket pooled around his feet. Noah raised his hands to placate him.

“Alright, alright. That’s off the table for you, then?”

“Of-of course!” Stiles felt the Omega inside him raging to not let anything take away what was inside him.

“I… I kind of expected that. It’s almost unheard of for Omegas to terminate a pregnancy.” Noah was a Beta, but he was well aware of what Stiles might be feeling at this point. When he found out Stiles was an Omega he’d done lots of research on what to expect – their rarity meant it wasn’t exactly an extensive topic in sex education or biology.

“I. I just can’t, Dad. It’s…”

“It’s fine, Stiles.”

“Really?”

“Of course. You’re eighteen, it’s your decision what you want to do here. And sure, I’m pissed off if I’m honest with you. This will throw a spanner in a lot of your plans, college being the main one. But you don’t need that from me right now. So, I’m going to put my anger aside while we discuss this.”

Stiles sat beside his Dad and leaned against him slightly “Thanks, Dad.”

“So. Options. You keep it. You put it up for adoption.”

“Mine.” Stiles grumbled.

“So, you’re keeping it?”

Stiles nodded “I… I’m scared shitless, Dad. I don’t have a clue what to do. But this… this baby is mine. And I’m going to have to find a way to deal with that. All I know is that deep down, I know that path is set for me now. It’s not just because I’m an Omega. I just can’t… couldn’t ever think of giving up my kid, you know? Hell, I've known about it barely twenty minutes and I'm already sure of that.”

“Right. And I’ll support you. But Stiles… the Alpha-“

“-I know who he is. And he’s… I’ll talk to him. See what he thinks.”

“If he’s an Alpha, once he knows he’ll want to be involved. They’re traditionally very possessive.” Noah reminded his son.

“I know. I know, it’s likely he’ll want to be a part of it. And… well, I’ll see what happens. But no, I’m not telling you who it is until I talk to him first. He might want to move states to avoid the other end of your pistol.” Stiles tried for humour and Noah let out a soft chuckle.

They sat in silence for a few minutes until Stiles stood with a weak smile and said “I’m going to take a shower then I’ll go and talk to him. Are you working today?”

“Not until this afternoon. But I’ll have my phone if-“

“Gotcha, don’t worry though. The Alpha… he’s alright.” Stiles tried for an encouraging smile before running up to the bathroom.


Approaching Derek’s loft, Stiles felt like his heart was in his throat. He took a few calming breaths before knocking on the big metal door and pulling it open. Derek had a pretty open-door policy with the pack.

“Derek?”

“Over here!”

Stiles followed the voice and the smell of bacon to the kitchen in the corner of the loft. A short breath escaped Stiles when he laid eyes on Derek for the first time in a few weeks. They texted a lot, but there hadn’t been a pack meeting since two Saturdays ago. Seeing Derek in a nice grey Henley, black jeans, cooking himself breakfast. Well... it was his knocked-up omega’s wet dream. Attractive, strong Alpha providing food. It was an instinctive reaction that Stiles took a moment to squash before he plastered on his best smile with a hint of serious eyes. 

“Want some bacon too?”

“Yes!” Stiles blurted out then flushed red.

“Hungry?” Derek smirked at his eagerness.

“Uhh… yep. Yes, starving. Famished. Can I have a drink?”

Derek nodded to the tap but sent Stiles a slightly curious look “Sure.”

Taking a swig of water, then another, then another, Stiles tried to calm his racing heart.

“Why is your heart beating so fast?” Derek asked as he placed two plates of bacon and eggs on the high table in front of Stiles.

“I… I have to tell you something.”

“Right?”

They both took a seat side by side at the table and Derek took a bite of his breakfast and waited for Stiles to talk. That was something Stiles always appreciated about Derek Hale; he was patient.

“I’m… God, how do I say this? Listen, I’m not here to make demands, or, or, like, whatever, I just… want you to know. I mean, you can be as involved as you like, because I’d like that, but also it’s not like… you don’t have to, you know?”

“Stiles, let me interrupt you. I have no clue what you’re trying to tell me. Can you go from the beginning?”

“We had sex!”

“Uhh… yeah? It was nice. Umm… would you like to do it again?” Derek looked confused but pointed at the bed in a fairly easy manner that suggested he wouldn’t mind doing it again.

Stiles’ cock twitched in his boxers and he felt slick start at his hole “Oh my God… fuck, not… not right this second, no.”

“Okay, that’s fine. I had thought it would be a onetime thing anyway… so. The beginning, we had sex, what’s happened that means you need to-oh.”

The penny dropped. And Derek went from a content, if slightly confused, Alpha, to one in shock, staring between Stiles’ face and his stomach.

“Yep.” Stiles popped the P.

“But… didn’t you get the morning-after pill?” Derek frowned, not angrily though.

“Exactly! Right!” Stiles burst out in a flurry of hand gestures “So yeah, had the pill, took it, all seemed a-okay. Then here we are six weeks later and I’m chucking my guts up every morning at 5am sharp. And I’m thinking what the fuck. I googled what it could be and one of the top reasons was pregnancy. Which I'd kind of suspected anyway. So my Dad got me a test and it turned out positive. And essentially me and you have super sperm and a super womb because this thing is apparently indestructible and now I’m pregnant.”

Derek put his fork down and sat quietly for a moment, still looking between Stiles and his flat stomach. He looked like a deer caught in the headlights.

“Oh, and to be clear, I’m not getting an abortion. Statistically speaking, it’s very rare an Omega would anyway because… base instincts and all. But anyway, I… I’m going to keep it. I know that kind of takes away your choice in this kid existing, but I want you to know… you’re welcome to be as involved as you want to be. Or not involved. That’s fine. You get that choice.” Stiles spoke with as much confidence as he could muster.

“I… Sorry, I’m just… processing.”

“I can see that.” Stiles said then distracted himself with the food Derek had made “Mmm… nice bacon!”

The loft remained silent except for Stiles’ fork and knife against the plate.

“I want to be involved.” Derek announced “I… Jeez, Stiles. I… I never thought this would happen. I’m… I’m not sorry it happened, but I’m sorry I put you in this position.”

“Hey, it takes two to Tango so let’s just move on from the blame game. I’m… I can barely get my head around the whole thing. But, I’m grateful you want to be involved. Because I think you’re a good Alpha.”

“You… you do?” Derek’s lips quirked up in a slight smile.

“Uh… duh! I mean, have you tasted this bacon?” Stiles lightened the mood with a smile.

“Thanks.” Derek said quietly then went back to eating, though slightly hesitantly. They both sat for a little while, neither wanting to break the silence. Simply settling in with the new reality that the pair of them, Derek and Stiles, were going to have a baby together.

“Hold on, did you say… your Dad – he knows?”

“Yep. Totally supportive of me and the offspring. I mean, pissed off, but supportive. Totally on the fence about you. In fairness though, he doesn’t actually know it’s you yet. I wanted to talk to you alone first.”

“Right.” Derek looked concerned “And… what do you think he’ll think when he knows?”

“Oh he’ll definitely use those silver bullets I got him.” Stiles said casually.

“What?!”

“I’m kidding! Calm down, man. Listen, honestly I think he’ll warm to you. You plan on sticking around and he’ll respect that. Also, he already thinks you’re okay. After he gets past the idea that you fucked and impregnated his eighteen-year-old son, you’ll be golden. Alright?”

Derek buried his face in his hands and groaned.

“It’ll be fine, Der. I’ll protect you.” Stiles rubbed Derek’s hair fondly then went back to his breakfast.

“And Stiles?”

“Mmm?”

“Do you… what are your… expectations… in regards to us?”

“Us?” Stiles said round a mouthful of food.

“Yeah. I mean, do you expect us to… be a couple?”

“Why would I expect that?” Stiles frowned.

“Well, we are having a child together.”

“Yeah… and I’m imagining we are going to be the best fucking co-parenting team anyone’s ever seen, alright? I’m talking joint birthday and Christmas celebrations, I’m talking us both doing the school run. And us both standing in the audience at a school play embarrassing our absolute star of a Tree Number 3 because we’re cheering so loud. Okay? I don’t expect anything from you romantically speaking. I mean, sure, it’d be cool if that happened. It’d be nice and whatever. But I’m… I guess I’m just alright if we stay friends. Why? What do you think?”

“I think our Tree Number 3 has the coolest Dad ever.”

Stiles grinned “If I’m Dad then you’re Papa.”

“Of course. And… I agree. I want to be a good parent. I want that to work with us. Romantically speaking I’d suggest we are of the same opinion. If feelings… develop… that’d be a bonus to the situation. But right now it’s just about you and the baby and making sure that’s okay.”

Stiles smiled “Thanks, man.” He nudged Derek’s shoulder with his own.


It took a little persuasion to get Derek to come back to the Stilinski House that morning “You’ll have to see him eventually! He’ll have more respect if you come with me when I tell him it’s you. Come on, I’ll be there.”

Arriving at the house in Stiles’ Jeep, Derek looked like he was about to be sick.

“It’ll be fine.”

“He has a gun.”

“Yes. And you have me. And claws. Though, use them on my father and I'll kill you. So come on, Sourwolf. Let’s go tell my dad you’re the super-sperm dude!”

Derek groaned and leant back against the headrest.


“Derek Hale.”

“Yep.”

“Derek Hale is the father of your child?”

“Yep. Co-parent. He’s gonna be involved, Dad. He wants to be a part of this.” Stiles put a supportive hand on Derek’s shoulder.

“Yes, sir. I will support Stiles and this baby as best as I can.” Derek stepped forward.

The Sheriff leant back against the kitchen counter, crossed his arms and gave Derek the most withering glare “Right. And tell me, Derek Hale, did it not cross your mind to use contraception?”

“Uhh,” Derek looked back to Stiles for help where there wasn’t much “…I’m a werewolf.” He turned back to the Sheriff “We don’t carry any diseases. And umm, it was all rather… spontaneous… ummm…” Derek looked to Stiles for a little help again, please.

“As I explained earlier, Dad, we took the necessary precautions. It just seems that the little dude or dudette presiding in my womb is particularly stubborn and strong. I don’t blame Derek, and I don’t want you to either. This whole thing just is what it is. And if I’m going to get through it I think I’m going to need both of you to have my back. Because I’m bricking it. Like, sure, when I think about it part of me is fucking thrilled. Absolutely beaming. Like, I've always wanted a family. But the eighteen-year-old kid inside me feels wholly inadequate and not in any way ready to grow a human, give birth to that human (because fuck that) and then bring it up. I mean, come on!” Stiles was rambling and beginning to let the edges of panic seep in. 

“Stiles.” Derek put his hand on Stiles’ elbow “I think you might want to sit down.” He guided him to the sofa and sat him down “It’s alright.”

Stiles hunched over and took some breaths “I’m gonna be a Dad. I’ll be rubbish. I can’t shove a baby out of me then feed and clothe it and tell it to eat it’s greens. I don’t even eat my greens. I can’t do this. This is a stupid idea. Why are we doing this?”

“Breathe, Stiles. In and out. Come on.” Derek crouched in front of him and gripped his arms “In. And out. In. And out.”

Stiles did as he said and felt his heart stop racing and his breaths calming.

“Listen, I know you’re scared. I am too. But we’re in this together now, okay?”

“Easy for you to say; you’re not giving birth in… oh my God, less than eight months!”

“I know. I know, but I’ll be right next to you every step of the way.” Derek looked right in Stiles’ eyes when he said that and they both knew it was true.

“Al-alright…”

“We’re going to take this one step at a time, kid.” Noah sat beside Stiles on the couch and put an arm around him “And you’re going to be fine.”

“Even if you hate Derek?”

“I don’t hate Derek.” Noah reasoned, which got him a look of surprise from both men beside him “Well, I don’t like him very much right now. But I know you’re a good man, Derek. And I believe it when you say you’ll be there for Stiles. And for now, that’s enough for me not to be loading my gun. I just need a bit of time to get my head around all of this.”

“One step at a time.” Derek nodded at Noah.

“Exactly.” Noah smiled.


Stiles spent the rest of the day on the couch. Derek stayed with him even after the Sheriff left for work. They watched some old movies, Derek made Stiles lunch, it was pretty quiet. So far they'd avoided discussing the situation.

“Shall we talk about it? Or do you want a bit more time not thinking about it?” Derek asked as the sun began to set, he sat at the end of the sofa beside Stiles’ feet and resisted the urge to lift them into his lap.

“Hmm… ignorance may be bliss, but I suppose we can talk about it. Just a bit. I reserve the right to freak out whenever I like though.”

“Of course.” Derek rolled his eyes.

“Well go on then, ask away, open the conversation.” Stiles flapped his hand.

“I thought, perhaps we may want to book an appointment with a Doctor. To check on you and… the baby.” Derek didn’t look Stiles in the eye, slightly apprehensive of his response. Stiles was on board with the baby plan, 100%, but he was still flipping between a enthusiasm and terror.

“Sure. I’ll call tomorrow before school. Book an appointment next week. Will you be coming?”

“If you… If you want me there?”

“Of course. You want to be involved, so I’d like you there.” Stiles said awkwardly as he fiddled with a loose thread on his jeans.

Derek couldn’t resist it anymore, he placed a hand on one of Stiles’ ankles, making the other man look up at him. Derek smiled “Thank you, Stiles. I… I don’t have much family left. This pack. They’re my family now. And this… the baby. I promise you I’ll look after it. Better than I’ve looked after anyone. I’ll be there for both of you. And not just because I should be, but because I want to be. This… the chance at a family. I never thought I’d get that again. But I’ll do my best to deserve it.”

Stiles sat up and pulled Derek into a hug. Derek wrapped his arms around Stiles’ back and took a deep breath in through his nose.

“Oh.”

“What?” Stiles pulled back.

“It’s just… you smell a bit like me. Like… in your scent.”

“Oh my God, really? Do you think the pack will know? I’m not ready to tell anyone else, Der…”

“It’s subtle. I think, for now at least, you can get away with just passing it off as spending time with me.”

“Phew! And… okay, this might be a bit weird. But we're kinda close, I mean, I’ve had your dick up my ass, so let’s just go with it-“

“What is it, Stiles?” Derek huffed.

“Can you… can you hear a heartbeat yet?”

“Uhh… not from here.”

“Yeah, I guessed that. I mean… what about if you listen against my stomach?” 

“I… I can try. If you don’t mind?”

“As I said. Dick, ass, we’re past all that. Come rest your ear on my belly, Wolf Boy.” Stiles grinned at Derek’s slightly reddened cheeks.

Stiles lay down on the sofa and Derek knelt beside him. With gentle hands, Derek lifted Stiles’ shirt with care and watched as a hint of goosebumps erupted on his flat stomach. He lowered his head and pressed his ear gently to Stiles’ flesh while looking up at the man’s face as he did.

“Anything?” Stiles asked after no more than a few seconds.

“Just… one minute…” Derek listened “I… with the noise of your other organs it’s a little hard. But yeah, I think I can hear… Can I just stay here for a little more?”

“Sure. Tell me if you can isolate the heartbeat.”

Stiles lay there for a few more minutes, quite enjoying the warmth of Derek’s head resting on him. It was comforting in a way he didn’t want to think about just yet.

“It’s… I can hear it. Definitely a heartbeat, it’s quick and quiet. Especially compared to yours. But yeah, I can hear it.” The smile on Derek’s face settled something inside Stiles. It made him feel like this was really happening and they could really do this. Together.

“Can you…”

“Mmm?” Derek hummed.

“Can you cuddle me? Just for a minute. I just…”

Before Stiles could finish his excuses, Derek climbed onto the sofa beside Stiles and curled around him. Wrapping an arm around his waist and leaning his forehead against Stiles’ temple, Derek held him close.

“Thanks.” Stiles whispered.

“You’re welcome. I… I like this too.” Derek whispered back.

“I’m glad you’re here, Derek.” Stiles rested a hand against the one Derek had on his waist “And I’m also glad our child will have your stellar genetics. Like seriously, you are jackpot material.”

Derek chuckled “Ditto.”

“Ha! You once called me a hyperactive spaz.”

“Who says that’s a bad thing? I happen to like your enthusiasm. And the thought of our son or daughter inheriting that from you – that makes me happy.”

A lump appeared in Stiles’ throat and tears came to his eyes.

“Are you crying?” Derek lifted his head to look down at Stiles’ face.

“I’m pregnant. There’s a butt load of hormones in me right now that I’m not prepared to deal with just this second, okay!? So I’m going to happy cry and you’re going to cuddle me because we did this to me.”

Derek huffed a laugh and went back to cuddling him as he cried softly.

“Also…” Derek whispered into Stiles’ ear “I like your eyebrows.”

That stopped Stiles’ tears and turned them into laughter. They lay on the sofa together, cackling. Euphoric in their surprise, joy, and apprehension. What a day.


It was late when Noah arrived home, the lights inside were off and the house was quiet. Putting his bag down in the living room he flicked a lamp on and was taken aback to find his son and Derek Hale on the sofa, fast asleep. Stiles lay on his back, snoring softly, and Derek lay between Stiles and the back of the couch, facing Stiles and breathing against his shoulder. Stiles’ shirt was slightly rucked up and Derek’s hand was splayed across his torso.

For a moment Noah thought about waking them, but then he remembered how tired Stiles had looked all day, and how every day for the last few days he’d woken up before dawn to vomit. And he decided to quietly head upstairs to bed.


“Oh-fuck!” Stiles launched himself off the sofa and made a sprint for the bathroom. Making it just in time he crouched before the toilet and emptied the delicious dinner Derek cooked last night into the basin. With a pitiful moan he rested his forehead against the cold seat and heaved.

“Stiles?” Derek’s nervous voice came from the doorway.

Stiles looked up at him for a second before screwing his eyes shut once more and vomiting again. When he caught his breath, Derek was knelt beside him and had a gentle hand on his back. “This… ugh… this is normal. Morning sickness. Every day this week. At five am.”

“That sucks.” Derek sighed.

“Mhmm. Mega sucks…” Stiles heaved again and just a bit of bile came up.

“Do you want me to get you some water?”

“No. No, just… stay here. Distract me.” Stiles begged.

And Derek did, he sat beside Stiles as he heaved and threw up, and he talked more than Derek Hale had ever talked to anyone. He talked about Laura. And her school play where she was meant to play the trumpet, but Cora had stuffed casserole in it the night before and she had to cancel. He talked about Cora. And how jealous Derek was of her when she was born because he liked being the baby in the family and he missed the attention. It made Stiles smile. Despite the discomfort and the exhaustion, the silver lining was listening to Derek open up a bit. It made the werewolf seem a bit more human to Stiles.

“I… I think I’m done.” Stiles sighed.

“Okay.” Derek helped him up and walked him up to his room. Once Stiles was in bed and cuddling his favourite pillow, Derek announced “I’ll get you some water. Do you need anything else?”

“Just water. Can’t eat yet.”

When Derek returned with the water Stiles was asleep. He placed the water on the bedside table and reached down to pull the cover further over Stiles. He didn't want him getting cold.
