How To Colossally Fuck Shit Up

Summary:

A story about Derek and Stiles building their family and trying to find their way to each other.

or

Stiles was looking at him expectedly.

Derek took a deep breath and prepared himself for the upcoming words. “But I wasn’t the only one he smelled like, Stiles.”

He looked pleadingly at Stiles, who'd gone deathly pale, and was now shaking his head.

“Stiles-, Eli is your son.” Derek forced out.

Stiles let out a small breathless sound of “Oh!”

He shot up from the couch and took his head between his hands, pulling his hair.

When that didn’t help to quiet the raging flood of questions in his head, he started pacing.

“What? -I mean…how? How is that even possible?"

"Why the hell would you keep that from me?” He was spluttering.

Stiles couldn’t believe what he was hearing.

 

Why would Derek do that?

Chapter Text

Stiles wiped sweat off his face.

There was no reason for the weather to be this hot since it was the last week of November already.

Stiles was back in Beacon Hills Preserve, which was not the way he wanted to spend his day off, but alas, what could you do when your idiot werewolf friend went and got himself killed.

It had been a long time since Stiles last went anywhere near the Nemeton. In fact, he couldn't quite remember how to find it again and thus, had been hiking in the woods since the early morning.

It was now 5 pm and Stiles needed another break so he sat down on a nearby rock to eat his protein bar and to drink some water. His backpack was filled to the brim since it had most of the things he had packed to travel. The stuff that he needed to bring Derek back was in a tote back laid in his feet.

It took some time to find the food from the full backpack and when he finally did, he bit into the protein bar hungrily, trying not to think about Derek, the Nogitsune or hellfires.

If Stiles had been smarter he would've probably asked one of the pack members to accompany him, but then again, he didn’t really want anybody to know what he was up to in case it didn’t work out. No reason for them to get their hopes up without a valid reason. Well, that was what Stiles told himself. The truth on why he wanted to do it alone, might have been a little bit more complicated. But he wasn't going to go there, not ever. If he could help it. Which, most of the time, he couldn't. It was totally his ADHD's fault.

Stiles winced when he realized his thoughts had, without his permission, drifted to Derek. The way he'd died had been unnecessarily cruel: burned alive, like most of his family, while his son watched and could do nothing.

Stiles blinked rapidly and took a deep breath redirecting his thoughts into finding the Nemeton.

After tucking the protein bar wrapper into his pocket, Stiles stood up and resumed his hike down the hill.

The leaves were rustling in his wake and the Sun was getting nearer the horizon, so Stiles picked up the pace.

Twenty minutes later he could finally see the stupid stump.

Stiles hurried to the Nemeton and rifled through his tote back taking out the seven herbs that were used to heal supernatural creatures, Derek's skull, salt, keys of Derek’s old Camaro, the black king chess piece, candles, incantation and two protecting feather necklaces that his mage friend Freddy had made for him.

“You owe me so much for this. This is the weirdest thing I've ever had to do.” Stiles muttered as he started making a salt ring on top of the tree stump.

He put on the necklace and set Derek’s skull in the middle of the ring with the keys and the chess piece.

Then he cut his finger, dropping three beads of blood on the skull's frontal bone. It was fucking morbid and Stiles grimaced.

After that he placed the seven candles on the salted edges of the circle and wrapped the different herbs around them.

Finally, he sat on the edge of the Nemeton and started waiting for the sun to set and the full moon to rise.

At 6 pm it was finally dark, if you didn't count the pale moonlight which was creating shadows on the tall trees surrounding the clearing.

Stiles lit up the candles and started reading the incantation that Freddy had made for him.

Per tenebras dominantium, per umbras reptans;
perditos e somno sempiterno voco.
Egredere, o spiritus, ignotis ab inferis;
Egredere a sepulcro tuo, ad quod missus es.
In virtute mortis, et in voluntate mearum.
Ad vivos redi, ut circulus imperat.
Redeat spiritus, incipiat pulsus;
Surge de cineribus, et exsurge, Domine;
De vita ad mortem, et de morte ad vitam,
Revoca formam, redi a lite.
Hanc ego noctem cum sanguine ligo ;
Nunc expergiscimini, nunc orimini, in pallido lunae lumine

Nothing happened after Stiles stopped receding the verses.

He looked at the skull that once was Derek’s head and started reading again.

Per tenebras dominantium, per umbras reptans;
perditos e somno sempiterno voco.
Egredere, o spiritus, ignotis ab inferis;
Egredere a sepulcro tuo, ad quod missus es.
In virtute mortis, et in voluntate mearum.
Ad vivos redi, ut circulus imperat.
Redeat spiritus, incipiat pulsus;
Surge de cineribus, et exsurge, Domine;
De vita ad mortem, et de morte ad vitam,
Revoca formam, redi a lite.
Hanc ego noctem cum sanguine ligo ;
Nunc expergiscimini, nunc orimini, in pallido lunae lumine

There was a small gust of wind and the candles flickered.

Stiles’ heart was hammering in his chest and he swore he could hear something as he started receding again.

Per tenebras dominantium, per umbras reptans;
perditos e somno sempiterno voco.
Egredere, o spiritus, ignotis ab inferis;
Egredere a sepulcro tuo, ad quod missus es.
In virtute mortis, et in voluntate mearum.
Ad vivos redi, ut circulus imperat.
Redeat spiritus, incipiat pulsus;
Surge de cineribus, et exsurge, Domine;
De vita ad mortem, et de morte ad vitam,
Revoca formam, redi a lite.
Hanc ego noctem cum sanguine ligo ;
Nunc expergiscimini, nunc orimini, in pallido lunae lumine

The small gust of wind turned into a big squall that blew the candles out.

The moon that had been lighting up the forest disappeared behind a storm cloud and Stiles blinked, trying to get used to the darkness that now surrounded him.

Someone coughed and Stiles saw something moving in the salt ring.

“Derek?” He whispered.

Red, glowing eyes snapped open.

“Oh, shit” Stiles whispered again. “Are you Derek?”

The figure in the salt ring stood up and cleared their throat. “I think so.”

Stiles’ tensed up shoulders dropped and he breathed out a sigh of relief.

“Oh, thank God! Welcome back, Sourwolf. I missed you.” Stiles sniffled after saying it.

He subtly wiped off the escaped tears and the edge of the salt ring and crashed into Derek, wrapping him into his arms.

Then Stiles remembered the feather necklace and put it on Derek's neck, after which he hugged the man again. Derek let him do so without protest.

“I hate you so much, you self sacrificing, stupid, fucked up idiot.” The relief Stiles felt made his knees weak and he clung to Derek more desperately.

Derek smelled earthly, like forest and sandalwood, he always did, and it calmed something in Stiles, making Derek feel more real than he had before.

“You are a liar.” Derek mumbled as he hugged Stiles back, his big arms engulfing Stiles as he buried his nose in his neck.

They stood there for a good amount of time, just clinging into each other and breathing the other in.

Finally Stiles took a step back enraged. “I’m so mad I don’t even know what to say to you.”

And then Derek was kissing him.

Derek Hale was kissing Stiles Stilinski.

And Stiles was opening his mouth and moaning into the kiss, pressing his body against Derek’s naked one and raking his fingers through his hair, pulling him in, in, in.

And then Derek pulled away from him, panting and looking flushed, and so delicious Stiles wanted to fucking devour him.

Stiles curled his hands around Derek's back and pulled him closer again. "Oh, don't you dare to stop now, Derek."

Derek leaned in again and pressed his mouth onto Stiles' and he noted, to his absolute delight, that it wasn't the only thing Derek pressed against him.

Stiles groaned and wrapped his hand around Derek's shaft.

“Stiles.” Derek moaned, thrusting up into his palm.

"Mhm?" Stiles got out, out of breath and desperate to keep being there, keep having Derek in his hand.

“Stiles, fuck me.” Derek rasped, his voice rough and wanting and so damn perfect.

And never in his life had Stiles imagined that those words would be leaving Derek’s lips.

Well, fine, -he might have imagined it, but he hadn't thought that the day would actually come.

Not that he was complaining. In fact, he thought it was the best idea Derek had had in the history of ideas.

In his shock, Stiles had let go of Derek's cock. He swallowed violently. “Are you sure?”

Derek nodded and started kissing him again, pressing against him, his cock rock hard and feeling huge against Stiles' thigh.

Stiles was acutely aware of the state of his own, equally desperate dick when he answered the kiss, hungry and desperate.

Stiles rocked against Derek for some friction, and as a reward, he felt sparks of pleasure shooting through him.

“I have lube in my backpack.” Stiles panted.

And fuck was he grateful for his past self that had wanted to jerk off comfortably.

He detached himself from Derek to riffle through his bag and pulled out the half empty bottle of lube. “Do you want me to use a condom?”

Derek shook his head no and pulled Stiles on top of him, wrapping his legs around him and helping him get rid of his t-shirt.

Stiles kissed him again and opened the bottle, squeezing lube on his fingers. “Tell me if you want me to stop.”

Derek licked his lips “I will.”

Stiles kissed his way down Derek’s stomach, all the way to his groin. Fuck, having a body like that should be illegal.

Stiles licked Derek's shaft from root to tip, simultaneously circling his fingers on the edge of Derek’s hole and pushing one inside.

Derek let out a punched out shout and Stiles took the man's cock in his mouth while slowly pumping his finger in and out of him, taking his time opening him up.

After Derek had had time to adjust to the intrusion, Stiles added another finger and started searching for Derek's prostate.

Derek whimpered as he found what he was looking for.

Hearing that noise was Stiles’ new favorite thing in the world and it had him moaning on Derek's cock. That in turn, made Derek jerk and Stiles choke a little bit.

Stiles kept grazing Derek's prostate every time he pushed his fingers back into him and Derek kept making the noises every time Stiles hit his target. Hearing them made Stiles' own erection throb almost painfully.

“If you keep doing that, I’m going to come before you get in me.” Derek bit out and Stiles pulled his mouth off Derek's cock with a loud pop.

“That’s okay by me.” And he sucked Derek back into his mouth, bobbing his head faster and adding a third finger.

Not a minute later Derek was coming down his throat, gasping.

Stiles fingered and sucked him though it, until the stimulation became too much for Derek and he squirmed off Stiles.

“Fuck that was good. I need you to get inside me now.” Derek panted unevenly, tucking Stiles upwards to kiss him again.

The kiss was open-mouthed, frantic and dirty and Derek could taste himself on Stiles’ tongue.

The taste was making his wolf rumble contently and Derek tried to distract himself from the fact by putting even more effort into each kiss and by leaving red marks on Stiles' back.

After a minute Stiles stood up, struggling to take off his shoes and jeans.

After winning the fight with his pants, he went back into kissing Derek.

“How do you want to do this?” Stiles asked Derek in between the kisses.

Derek wrapped his legs around Stiles’ waist. “Like this. Just, get in me already.”

“Okay, okay, I can definitely do that.” He babbled and lubed up his cock, slowly starting to push inside Derek. “Fuck, you are so tight.”

Derek hummed impatiently and pulled Stiles all the way inside him by tightening his legs around the man.

Stiles let out an undignified yelp as he was surrounded by Derek.

It was so good he had to squeeze his eyes shut so he wouldn't come immediately.

Derek had never in his life felt so full.

He loved the thought of Stiles filling him.

Derek's dick was hardening again against Stiles’ stomach and he let out a whimper at the sensation that was almost too much, but at the same time, not enough.

“Move.” Derek ordered roughly, his brain not allowing anything more complex to pass his lips. It lacked the ability to form any intelligent thought at the moment.

“You have to wait a little while longer, big guy, or this is going to be over before it starts." Stiles grunted. "Fuck, Derek, you look so beautiful, and you feel fucking perfect.”

Derek was suddenly glad that it was dark, because Stiles saying that to him made his face redder than he could remember it ever being.

And fuck if that wasn't a revelation Derek didn't want to have. Because nobody made Derek Hale blush.

Then Stiles started to move. First it was slow but gradually Stiles picked up the pace. Derek couldn't think of anything, except for the litany of “faster, more, please, harder” that escaped his lips in varying degrees of desperation as Stiles kept fucking him, from the perfect angle. Every time Stiles thrust in, Derek could feel a jolt of pleasure climbing up his spine.

Stiles wrapped his long fingers around Derek’s cock and started jerking him off in the same rhythm he was moving inside him.

It didn't take long before Stiles was coming with a guttural groan and Derek followed him, ropes of his cum shooting onto their stomachs.

After a little while Stiles pulled out of Derek slowly and rolled off of him onto the tree stump.

“I can’t believe we just did that.” He panted, trying to catch his breath.

His fast beating heart was finally slowing down, and he looked at Derek who was laying next to him on the Nemeton.

Derek was feeling strangely empty now that Stiles wasn't inside him anymore.

Holy shit, what had they done?

Stiles wiped himself down with his used t-shirt and handed it to Derek who did the same.

“Derek, you okay, buddy?” Stiles asked, sounding unsure.

Derek realized that he’s been quiet for a while.

“I’m fine.” He said roughly, without being sure that he actually was.

His body was tingling in a strange, overwhelming way and he felt like he wanted to shake his skin off his bones to rid himself of the feeling.

Derek had just had sex with Stiles, who he'd been in love with, unrequitedly, for over a decade.

“Do you have any spare clothes for me?” He asked.

Stiles sat up and tossed him a t-shirt and grey sweatpants.

Derek dressed up and Stiles followed suit.

Stiles looked unsure and cleared his throat. “You know, Eli is in LA, he is living with Scott and Allison. Nobody knows you are back, so I brought your phone and you can call them.”

Derek paled and his heart missed a beat. Eli.

“Thank you. Can I have it?” He asked gruffly.

“Of course.” Stiles chewed his lip and handed him the phone.

“Are you sure you are okay?” He added, eyebrows furrowed.

Derek nodded. “I’m fine. I just have to call Eli.”

“Okay.”

Derek found his son’s number and pressed the call-button.

It rang four times before Eli answered. He sounded devastated. “Who is this?”

“Hi, kid. It’s dad.”

There was a sob from the other end of the line and hearing it broke Derek's heart.

“I’m okay, kid. I’m in Beacon Hills and I’m getting the first plane ticket there. You can send me the address.”

“Dad, is it really you?” Eli asked, sounding a little bit hysteric.

“I promise you, it's me. I love you, kid.” Derek said, desperate to let his son know that he was, actually, well, -him, but not sure how to do it.

Tears stung Derek's eyes and he swallowed back his own sob, only sniffling a little.

“Okay, okay, I believe you. How are you back? You were…” Eli choked on another sob and Derek grimaced. His death must have been horrible to watch.

“I know kid, I’m all better now, Stiles did something and I’m okay. I promise you, I’m not leaving again.”

It felt so hollow to say that, like Derek had just been on a long business trip and not burned to death and brought back to life. And it wasn't as if he could actually be sure that he could keep his promise either.

“Okay, dad.” Eli sniffled.

“Is Scott or Allison there? You probably shouldn’t be alone now kid. Can you go find them?”

Derek heard rustling from the phone as Eli moved out of the room he had been in.

“Scott is here. Scott, my dad is back! I’m putting you on speakerphone.”

“What’s going on Eli?” Scott's gruff voice carried through the air.

“I'm putting you on speakerphone too. Hi Scott. I’m not dead anymore.” Derek said and winced.

“Derek?” Scott sounded suspicious.

“It’s really Derek, Scott. I totally did something bad-ass to bring him back. We are in Beacon Hills.” Stiles putted in from where he had been watching.

“Holy shit, dude! That’s awesome! Nice to hear from you Derek. I can’t believe you are real, that’s awesome! Eli, your dad is really back!” Scott gushed. “Are we coming there, I can get the car now and we can start driving there!"

He didn't wait for the answer. "Eli, pack a back, we are going back to see your dad.”

“Well, if it works for you, it sounds good. I was going to come there but that works too. I’m going to go to our house so I’ll be waiting for you guys there.” Derek smiled.

“Okay, I love you dad. I’m gonna go pack now.”

“I love you too, kid. Thank you, Scott. See you soon.”

Eli ended the call.

“Okay, let’s get going, sourwolf.” Stiles grinned forcefully and started heading out of the forest.

“Stiles, you are going in the wrong direction.” Derek pointed to the fastest route out of the Preserve and smirked when Stiles flailed, redirecting himself into the right direction.

They walked in silence and Derek could practically hear Stiles overthinking things.

More than once Stiles opened his mouth to speak, but he never got to the point of actually saying anything.

Derek sighed. “You know you don’t have to worry about it, right?”

“Worry about what? I’m not worried!” Stiles squeaked, his heart rate jumping and exposing the lie.

“It was a mistake and it’s not going to happen again, so you can just forget about it.” Derek forced out roughly, swallowing down the stupid feelings he had towards Stiles.

Stiles was quiet for a while. “Why?”

“Because it didn’t mean anything.” Derek said through gritted teeth.

What the hell else was there to say? By the way Stiles, I have been hopelessly in love with you for the last fifteen years? Yeah, right! Derek would rather keel over again than open that can of worms.

Stiles’ shoulders slumped. “Okay.”

They kept walking in silence.

After what felt like forever, they came up onto the road.

Derek turned to the left.

Stiles cleared his throat. “My car is actually in the other direction. Do you need a ride to your house?”

“I think I’m fine just walking. You are leaving?”

“Yes. I'm working in Sacramento and I have to drive back there by tomorrow anyways.” Stiles said smiling. “I’m very glad that you are back Derek.”

“Thank you, for bringing me back, Stiles.” Derek looked at him with a serious expression.

“No worries!” Stiles’ answering smile was super bright and the fakest one he could remember himself ever making. He grimaced, looking at the blacktop.

Derek frowned looking at the other man-, Stiles didn't really seem all that glad that Derek was back. Derek forced himself to stop thinking about that.

Stiles hadn’t felt as lonely as he did in that moment in a long time.

And before Derek could see the tears in his eyes, he whipped around and started marching toward his car.

Finding the car took about ten minutes and Derek was, thankfully long gone by then, so Stiles could climb into the driver's seat and let his tears fall freely.

He was probably the stupidest man on earth.
