Spencer Reid x Stiles Stilinski
im dedicating this story to the two people who asked for a Spencer/Stiles story, i'm so sorry it took a million years but i hope you guys love it, i can't wait for your comments. <3

@SincerelyAngelBerry for the extended idea to the ship.
@24_WhoAmI_A5 for being my favourite commenter in this book, can't wait to see what you come up with this time.

I hope it was worth the wait (JK nothing is worth that long of a wait, sorry everyone :) but i still hope you enjoy reading it as much as i enjoyed writing it. let's see if my writing skills disappeared while i was gone)

-------------------------------------------------

It was Stiles' first day back at school after Christmas break and he was already late. He got back from Beacon Hills late the night before, after visiting the pack, and he overslept. Being in the pre-FBI program was easy for him with all his knowledge of law enforcement and his genuine curiosity for the field so normally he wouldn't worry but his teacher had informed them that a very important guest was coming to share his experiences and his knowledge with the class and Stiles didn't want to miss a single second of it.

He rushed through the door to his class and managed to be only three minutes late and it seemed like the lecture hadn't started yet. Stiles sat down with a sigh of relief, mentally thanking the pack because he could now run fast enough to escape a werewolf trying to kill him, in fact he had actually done that, multiple times. It all worked in his favour though as he sat down and waited for the class to start. 

His regular professor came up to the front of the class and all the students quieted down to hear what he had to say "Okay everyone, listen up. As promised, today we have a very important guest lecturer. Dr. Reid will be sharing some of his experiences from his time in the behavioural analysis unit of the FBI." Stiles could barely hold back his excitement, getting into the BAU had been his dream for years now. he was so glad he didn't miss a single second of this class. He had no idea that staying for this lecture would also change the course of his life forever.

He spent the whole hour asking as many questions as he could, participating every time the Doctor asked a question himself. When the lecture was over, Stiles couldn't help but be disappointed, so he decided to take a chance and go to the front of the room. "Excuse me Doctor Reid?" the young agent looked up from where he was packing away his belongings, a smile spreading on his face when he saw who had come up to him "Stiles, right? i have to tell you, i don't think i've ever given a lecture where a student asked so many questions AND actually laughed at my jokes. it was definitely a refreshing difference." he said with a laugh.

Stiles almost forgot the reason he even came up to the Doctor when he heard him laugh, it was genuinely one of the best sounds he'd heard in his life. luckily he only stared for a few seconds before regaining his bearings and speaking up "well i'm glad you feel that way, it gives me hope that you won't say no to my offer" he spoke nervously, rubbing the back of his neck. he was much less nervous before he came closer and realised how gorgeous this guy was, Stiles really thought he was done with getting Bi panics after his freshman year of highschool. "Offer?" 

"Yeah, i was actually hoping you would come get some coffee with me, i'd love to pick your brain a little more. Joining the behavioural analysis unit has always been a dream of mine, i hoped you could give me some advice and maybe tell me some stories or something. you don't have to of course, i mean you would get a free cup of coffee out of it. actually i don't even know if you like coffee, we could go somewhere else, or i could buy you lunch. or we could just not do anything, yeah just forget i asked, we don't have to go anywhere. you're probably busy and-" he stopped mid-sentence when he heard that beautiful laugh again.

"Sorry, sorry. i don't mean to laugh at you, i just finally realised what it's like for my friends when i start ranting about something. i would love to get a cup of coffee with you, my flight doesn't leave until tomorrow morning and i was just gonna do some paperwork in my hotel room tonight. also first piece of advice, i don't think you'll find a single agent who doesn't like coffee, we practically live off the stuff when we're on cases, me especially." 

Stiles let out a breath of relief at that, laughing slightly at his own ridiculousness "right, noted. well, shall we Doctor Reid?" he said, motioning to the door behind him, his breath stuttering slightly at the smile sent his way "Spencer, please" the slightly older man corrected. "Spencer it is then" the young student replied, turning around quickly so the man couldn't see the blush covering his cheeks at the immediate thought crossing his mind as the name left his mouth. "now that is a name i could see myself saying for the rest of my life" 

They had coffee together, talking non-stop the entire time. it started as just information about the BAU and what Stiles could do to get in, but after a while they just started exchanging life stories and getting to know each other better. Stiles hadn't made many friends in college, so it was weird for him to talk to someone for so long and not be able to mention his "other" life, but it was also kind of refreshing. Spencer enjoyed talking to him more than he ever had any other stranger, he didn't know what it was but something about Stiles Stilinski was just different.

By the end of the night, they exchange numbers to keep in touch and go their separate ways. they keep in almost constant contact for months after that, though not able to see each other again in person until almost six months later. Spencer had a case in California, in the same city as Stiles' college so they made plans to see each other again. Spencer was supposed to come to Stiles' apartment for dinner and then a movie night when he was done with the case. Stiles, with all his near death experiences, had never been so nervous in his life.

they had been talking for six months, but other than the occasional joke flirting, Spencer had not shown that he was interested in Stiles in any way other than being his friend. they had both come out as bisexual to each other pretty early on in their friendship but that didn't mean the agent was attracted to him. Stiles was terrified of losing his new friendship, but he had to take his shot or he knew he would regret it for the rest of his life, he was planning on confessing his feelings to the doctor after dinner, but much like everything else in his life, the plan went out the window. 

Spencer had shown up to his door in jeans and a t-shirt, his hair messy and some strands getting in his eyes as he had been growing it out a bit lately. he wasn't wearing anything special, and it's not like Stiles hadn't seen him in pictures and video calls in the last six months, but the second Stiles opened the door he couldn't hold in his gasp. "I'm not under dressed am i? i know you said we were going to stay in, so i just decided to be comfortable. I can't tell if the way you're staring at me is a good thing or a bad thing, seriously please say something because i'm too tired to profile your expression right no-" he cut himself off abruptly when suddenly hands were on his face and Stiles was much, much closer

"can i kiss you?" the younger man questioned, his voice quiet and an octave deeper than Spencer was used to, but he didn't hesitate to pull him the rest of the way in, connecting their lips in a passionate embrace. Stiles pulled away slightly, letting out a breathless laugh "I had a whole plan to tell you how i felt after dinner, but damn do you look good right now Spence" they both smiled into their next kiss as they connected again, walking further into the apartment and closing the door behind them "I'm glad you didn't wait, now we get to do this all night" Spencer replied.

the reached the couch, still connected, until Stiles put his hand up the older man's shirt "We should skip dinner" he suggested as he tried to pull him back in, but Spencer stopped him "no, i'm starving right now. plus you'll need the fuel for later" that was the last thing Stiles expected to come out of the usual shy doctor's mouth, but he was definitely not complaining, especially since Spencer was right, he definitely needed that fuel. (A/N if you understood that reference, i love you and we should be friends) 

Their relationship for the next year and a half is almost perfect, they have to be long distance until Stiles graduates and moves to Quantico, but they make it work. neither of their friend groups know about their relationship, though they figured out a while ago that the both of them were seeing someone, just not who. Stiles never thought he could handle a long-distance relationship but he soon learned that his boyfriend was worth it, they called every night until they fell asleep and they visited each other as often as their crazy lives allowed. they told each other everything, well almost everything. Stiles felt guilty about it, but he couldn't tell Spence about the Supernatural beings that filled his life.

On one hand, he couldn't betray his friends' trust by telling their secret and putting them in danger, but on the other hand he was also scared. he couldn't bear the idea of his boyfriend not believing him, or thinking he's crazy and leaving him, so he decided to keep it a secret, he thought that maybe one day Spencer could meet the pack and he could tell him with their permission, and also with proof in front of him. until then though, he chose to hide the biggest part of himself, not knowing how much it would end up hurting him in the end. 

Spencer has a case in Beacon Hills at the same time that Stiles goes home for his summer break, and they plan to see each other as much as possible, while also maybe introducing their friends and family to the other. Reid's team was already working with Sheriff Stilinski so at least Stiles would have a few days to see how his dad felt about his boyfriend as a person, before telling him they were together. Noah already knew that his son was dating someone for a little over a year now, and he knew that it was a guy. Stiles had come out to his dad years ago, and he had always been very accepting about it, so he wasn't as scared as he thought he would be to introduce them. 

Unfortunately, his plans were put on pause for a while because there was a new Supernatural creature attacking people in town, again, so the whole boyfriend meeting everyone thing was in the back of his mind for now. it took Stiles longer than he would like to admit to realise that the guy they were trying to stop, was the same serial killer that the BAU were here to find. he spent the whole case trying to avoid running into his boyfriend at a crime scene or anywhere else that would seem suspicious, but when had luck ever been on the young Stilinski's side. 

(A/N: to make it easier to understand, Derek = Derek Hale, Morgan = Derek Morgan, unless otherwise blatantly stated, for dialogue) 

It didn't take the pack long to realise that it was another werewolf in town, though he was clearly out of control or just full on insane. Stiles and Derek decided to track down a lead together, for a possible hideout for the creature. when they got there, the alpha picked up a scent but it was too faint to be able to use, so he decided to shift into his wolf form to heighten his senses, leaving to another room so he could strip off his clothes. a few minutes later Stiles tripped on a random piece of wood in the messy cabin, tumbling down to the floor with a yelp. Derek, as a wolf came back into the room and tilted his head, as if in question, which made the younger of the two smile at his friend as he stood back up "I'm fine Sourwolf, just messed up my clothes a bit. go find something we can use" 

Stiles tried to fix his shirt as the wolf turned back around, but he had no luck, his clothes were covered in dirt and somehow his hair had gotten all messed up too. just as he was about to call out to see if his friend had found anything, he heard a car door slam outside. "Sourwolf! we got company, might be time to change back!" he didn't know if it was the rogue wolf coming back home or someone else, so he tried to stay quiet, only letting out a quiet "crap!" when he realised who walked through the door. "don't come out yet, it's the feds, let me think of a good excuse" he whispered, knowing Derek would hear him anyways. 

Stiles comes out from the corner, facing his boyfriend and his best friend, Morgan, his mind supplied from the descriptions and pictures he's received. He can see Spencer about to open his mouth to question him, when the other agent beats him to it, taking his gun out of his holster but not raising it yet. "who are you, what are you doing here?" he instantly questions, with an aggressive tone. Stiles is normally great at thinking on his feet, especially when it comes to quips and ridiculous explanations, but the sight of his boyfriend stops him short. he hadn't seen Spencer in over three months because of their schedules, and god he missed him so much. he didn't realise he was quiet for too long until he heard footsteps coming out of the other room, probably thinking he needed help with an excuse.

His jaw almost dropped when he saw Derek coming out with his shirt halfway down his torso and his belt unbuckled "oh god, please don't tell me he's about to say what i think he's about to s-" "sorry i took so long Babe, i have no idea where you threw my shirt and i had to clean u- oh hi" "god fucking damn it Derek Hale, you couldn't have come up with any other explanation, i'm gonna fucking kill you the second we're alone" Stiles thought bitterly as the wolf turned to smile at the agents innocently, as if he hadn't just imploded the best thing to ever happen to his friend. "Oh my god are you guys those FBI agents working with Stiles' dad? crap we're not in a crime scene or something are we? this is just where we always go when we want to be alone, it's a great place for-" he tried to hold back a grunt as Stiles elbowed him in the stomach, instead putting an arm around him. 

"Were you two...?" Spencer couldn't even finish the question, looking back and forth between who he thought was the love of his life and this random guy he had never heard of before. He knew the answer, but he was still holding out hope that Stiles wouldn't break his heart, not like this. "yes" "no" Derek and Stiles replied at the same time, the older of the two not noticing the desperation in that one word coming from his friend, instead pinching his side subtly to get him to shut up. "we're sorry agents, we really didn't know this place was part of your investigation. we'll leave you alone to do your jobs, we wouldn't want to keep you long." Derek continued, still smiling at them. 

"Yeah i'm sorry, i'm so fucking sorry" Stiles said, clearing his throat to reel in his emotions as he looked away and continued "...you know for interrupting the scene and everything" They walk past them and out the door, but not before Stiles could catch the look of complete devastation on his boyf- probably ex-boyfriend now's face. He wouldn't be able to forget that look for the rest of his life, and he will never forgive himself for breaking the doctor's heart, even if it was never his intention. the second they were out of earshot of the cabin and almost to the car that they had parked further away, Stiles pushes Derek away from his side "What the FUCK was that?!" 

"That was me covering for us, you weren't saying anything and i had to come up with something before the both of us were arrested!" Derek replies defensively "and that's the best you could come up with? do you any clue what you just did?!" Stiles yells back as he rubs his face with both hands, trying to stop the tears that will inevitably fall at the fact that he just lost the love of his life, over a dumb lie. why couldn't he have just told him the truth a long time ago and saved them both from this hurt. he doesn't say anything else as he walks to his jeep and slams the door shut, waiting for Derek to climb into the passenger seat while seriously contemplating just leaving him there to walk back to the loft. 

The car ride is silent for a while until Derek finally speaks up "does the reason you're so mad at me right now have anything to do with the fact that as we walked out that guy with the brown hair reeked of sadness and heartbreak?" Stiles flinched at the confirmation of what he already knew to be true. he let out a long breath to calm himself, wiping a few tears that had started to fall, knowing that it wasn't actually Derek's fault, he didn't know the consequences of what he was doing. "His name is Spencer and he's my boyfriend...or i guess he was. He's never gonna forgive me after today, no matter how i try to explain. I met him at one of my lectures at school and we just clicked i guess, he was the most adorable, sweetest guy i had ever met. i was gonna tell you guys soon, when i was ready, we've been together for a year and a half. i love him with all my heart, with every fiber of my being, i was gonna spend the rest of my life with him but now he's never gonna wanna talk to me again."

Derek tries to comfort him with a hand on his arm, "I'm sorry Stiles" he shakes his head in reply "Don't be, you didn't know. it was probably never gonna work out if i had all these secrets between us anyways. i should've known better than to fall for someone who doesn't know about all this bullshit in our lives. Whatever, let's just go back to the loft and talk to the rest of the pack, see if we have any new information" Stiles and Spencer continue to work on the case separately, though neither of them could stop their minds from drifting to each other, or the last text conversation they had. 

-----------------------------------------------------------

Spence (LOML and my future husband)
            -How could you

Sti <3
           - I'm sorry
           - I love you 

-----------------------------------------------------------

The BAU is able to track down the Unsub before the pack does and they chase him until they get to the middle of the woods. When they finally get close enough to see him face to face, they all freeze. Either this guy has had hundreds of cosmetic surgeries or....he's not human. In their shock, they didn't notice the thing getting closer until it jumped on top of Reid and tackled him to the ground, the rest of the team shouting his name but not knowing how to help. Spencer could see his life flash before his eyes as a clawed hand moved quickly towards his throat, but then he heard a familiar voice let out a shout. "Get the fuck off my boyfriend Wolfy!"

The yell was accompanied by Stiles swinging a big metal bat to the head of whatever was on him, making him fly to the side. He recovers quickly, too quickly, and goes to grab the bat, only to pull away instantly as if he had been burned. "That's right bitch, got a new upgrade. Made from mountain ash and dipped in wolfs bane asshole" Stiles smirked at the creature as it got angrier by the second "Stiles?" the doctor asked incredulously, as he finally started to catch up with what was happening in front of him "get behind me, now Spence!" he yelled, not taking his eyes of the threat.

"This is my town and it is protected territory, you chose the wrong pack to fuck with kid" the wolf growled in reply and tried to lunge at him, Stiles backed away at the last second "Scott! Derek! Now!" on cue, they both jumped down from a tree and flashed their red eyes, letting out load roars to weaken the omega, bringing him to his knees. Stiles rushed over and injected him with a strong sedative, laced with enough wolf's bane to knock him out without killing him. "That should keep him down for a few hours, call the others to take him to Eichen, i need you two to stay here and help me explain all of this. Go check on the other agents in the mean time, i got this one" he finally turned to look at Spencer as he said the last part, waiting for them to leave before he started talking, even though he knew they could still hear every word.

"Are you hurt anywhere? That looked like a pretty nasty tackle before i reached you." Tears started to form in Spencer's eyes as he came face to face with Stiles, only days after what happened. He couldn't bring himself to reply until the younger man came closer and put a hand on his cheek, "Hey talk to me Baby, are you hurt?" he reacted instantly now, pushing the hand away from his face "don't call me that, you think just because you saved me i'll suddenly forgive you for cheating on me for who knows how long? I'm grateful, don't get me wrong, but i can't just forget what you did, you broke my heart Stiles. So no, physically I'm not hurt, thanks for asking" he tried to walk away but Stiles quickly stopped him with a hand on his arm.

"Please just let me explain, i thought i would lose you forever because i couldn't tell you the truth, but now that you've seen it, i actually get a chance to make this right. i know you hate me right now, but just let me tell you what you really saw, and if you don't believe me or you still want to leave i won't stop you" the young doctor just nodded in reply, not trusting his voice anymore and Stiles sighed in relief at the chance he was getting. "I have never and would never cheat on you, not in a million years. I love you more than you could ever imagine, you are my entire future, i wouldn't throw that away for anything. Me and Derek were at that cabin running down the same lead that you guys found, i tripped and my clothes got all fucked up, which i now realise just made everything worse. It took me a second to come up with a reasonable excuse for why i was there in the first place because it was my first time seeing you in person for months and i got a little distracted. Derek didn't know that and he thought i couldn't figure anything out so he came up with that stupid plan because apparently his horny little wolf brain can't think of anything on the spot other than sex"

"Hey! i heard that!" came from the short distance, "Shut the fuck up Sourwolf, i'm trying to get my man back and fix the mistake you made!" he heard mumbling but didn't give it any attention "Spence, Baby, you are the love of my life and i wouldn't give that up for anything. Please tell me you believe me? tell me i can still call you mine. tell me that i didn't fuck up the best thing to ever happen to me. i understand if you still hate me, if you believe me but still can't forgive me for keeping all this from you. i'm okay with you hating me for everything else, well not okay, i'm gonna be heartbroken and i'll never find someone like you again. but all of that doesn't matter, i don't matter right now, just please tell me you believe that i would never cheat on you. i will never forgive myself if i'm the reason your heart stays broken, if i become the reason you don't trust anyone anymore. i can't stand the idea that you might blame yourself for it later in life, think it's something you did or didn't do. you have been the most perfect boyfriend anyone could ever ask for, and the next person you fall for is gonna be so damn lucky to have you. oh God now i'm thinking about you with other people, which is totally fine! actually no, it's not, but again, my feelings don't really matter right now, no matter how crushed and possibly suicidal i'll be, as long as you're happy and they treat you right and- and- are you laughing right now!?"

Spencer nodded as he tried to catch his breath between laughs, holding onto Stiles' shoulder for balance "Sti, Sweetheart, somehow the conclusions you reach while rambling are even worse than when we met two years ago. how did this go from you apologising to you basically telling me that it's okay if you kill yourself because i'll be happy in another relationship?" Stiles opened his mouth to reply, but before he could he had hand on his hips pulling him closer "You're ridiculous and i love you so much" Spencer said before pulling him even closer, connecting their lips in a kiss that soon turned desperate by the younger man "i love you too. Does this mean you believe me? because this is gonna be really awkward if you're about to break up with me" 

Spencer rolled his eyes, but stayed smiling as he did. he wiped away the few tears from his boyfriend's face and gave him a light, chaste kiss.

"yes Sti, i believe you" 

--------------------------------------------------------------------------

Stiles ends up joining the BAU when he graduates and finishes the academy, the team solves a lot more cases now that they know about the Supernatural world and what to look for, as well as what to do when they come across one, having Stiles on the team boosted that number even more. The team were very fortunate that SSA Stiles Reid became a part of their team, and their family.

A/N: i make no promises that i'm gonna return any time soon, but let's hope i can finish these finals and get back my love of writing. this definitely helped remind me how much i love it <3
