Prompts: Research + Loft
Summary: It all started at the loft, when Stiles was first stuck doing research with Chris and Peter. Over the months, Stiles notices the tension between the two and he thinks he knows exactly what it is. Sexual tension. He’s not wrong, but he’s missing one big part of the equation: Himself.
Longing at the Loft
Stetopher Week 2026
“Christopher,” Peter’s voice was a barely contained growl.
“Peter,” Chris’ finger twitched like he wanted to reach for his gun.
“Stiles!” Stiles yelped annoyed and waved his arms, startling both men out of their glaring contest. “Now that we finished roll-call, can we move on to the research?”
Peter’s lip curled to show some fang as he stared at Stiles. “There is a hunter in the den.”
Blinking slowly, Stiles looked from Peter, still standing on the spiral staircase, to Chris, still standing in the open door. “Wow. Nothing gets past those keen werewolf senses, does it?”
It earned him a low warning growl that, half a year ago, would have filled Stiles with dread, anxiety and the urge to flail and run. Since then, Stiles had faced the then feral Alpha multiple times, aided in killing him, had faced hunters, gotten kidnapped and tortured by said hunters, and dealt with a killer lizard. So Stiles was kind of over it. Peter Hale did not intimidate him anymore, they’d long since moved on from that first meeting in the hospital that had left Stiles with his heart in his throat.
“I know there is a hunter in the den, I let him in,” Stiles grabbed Chris by the wrist and actually pulled him into the loft, startling the hunter and earning another growl from Peter.
“Why would you do that,” Peter asked, voice sharper than his teeth.
Stiles closed the door. “Because Derek, our Alpha if I need to remind you, invited him.”
“And why would he do that,” Peter asked next. “And why would I not know about that.”
Stiles gave his most unimpressed deadpan. “Probably because of this exact reaction. Derek knew you would take this poorly and decided to not deal with that and leave it up to me. I don’t know at which point the pack collectively decided I’m the designated Peter wrangler, but here we are.”
That earned him a surprised snort of a laugh from Chris and a narrow-eyed, offended glare from Peter. Well, the wolf could just suck it up because it was true. Sure, there were multiple members of the pack who got along with Peter to varying degrees – Erica was a big fan of him, Peter and Jackson had some kind of fashion and judgment bonding going on, Cora and Peter had a moderately functional relationship (for two Hales, anyway…) – but when it came to needing to making sure Peter actually did what he was supposed to, everyone was suddenly looking elsewhere and Stiles got stuck on Peter sitting duty (mh, he wouldn’t mind sitting on Peter. Either on the man’s face, or his dick, Stiles wasn’t picky on that. Hey! That man was fine as hell, no shame in having two eyes and being able to admit that, especially now that he was no longer a feral murderous threat to everyone Stiles loved and instead was on their side. He could enjoy the view).
“Stiles,” Chris snapped his fingers in front of Stiles’ face, startling him. “You spaced out.”
“I’d love to know where your mind went there,” Peter cocked one eyebrow.
There was a leer on Peter’s face. Right. Werewolf senses. Stiles flushed and hoped his scent hadn’t given away too much. Glaring at the wolf, Stiles gave him a shove and headed to the couch.
“Research,” Stiles pointed at the stacks of books on the table. “Since we hit a dead end with the books from the Hale Vault, I suggested we tap into the hunter knowledge. Argent bestiary, hunter experience, new perspective. Derek brooded, eyebrowed and then growled his agreement.”
“And why would he agree to that?” Peter asked, shooting Chris a look at ‘he’.
“Oh my god, he is literally in the room and you could ask him yourself! We are not in first grade anymore and I am not passing on messages!” Stiles groaned and flopped down on the couch.
However, Peter seemed to not be the only uncooperative party involved. Chris still stood exactly where Stiles had put him before closing the door and he didn’t seem willing to answer either. This was great. Amazing. Derek owed him so hard for this one.
“Because our resident Argents agreed on a treaty with the Hale Pack,” Stiles looked from Chris to Peter, raising his own eyebrows. “As Derek’s newly appointed Emissary, I helped him negotiate it. One of the conditions both sides agreed on was to share knowledge and resources. We all have the same goal. Protect Beacon Hills from supernatural threats. This, surprisingly enough, works so much better when we actually work together instead of against each other.”
The sneer returned to Peter’s face and Stiles was honestly five seconds from throwing mountain ash in his face or something. Derek was so going to buy him the new Call of Duty for this shit. When Stiles had agreed to become Derek’s Emissary, after he figured out that his ‘Spark’ meant he had actual real literal magic, he had somehow imagined that to be more badass witch fights and less playing mediator between two stubborn, deadly, hot old men who clearly had personal history. Stiles just wasn’t entirely sure what it was; just the general hatred between hunters and werewolves, the overall bad blood between Hales and Argents, the indirect ‘your sister killed my family’ and ‘you killed my sister and my father, and your nephew killed my wife’ type, or if it was something more personal, if the two of them had tried to kill each other in the past.
“Just sit down, both of you,” Stiles ordered annoyed. “The sooner we start, the sooner all of us can go back home and not be here and not do this.”
/break\
So there may be a secret fifth option that hadn’t occurred to Stiles. In Stiles’ defense, all the bad blood and murder-y vibes on both ends, so something on that spectrum was the more obvious conclusion. However, over the weeks of research meetings at the loft, Stiles noticed that the growling and the tension between them was of the sexual kind. The ‘we used to fuck and it ended badly’ kind. So, in a way, Stiles had been right after all! All the murder-y vibes were most likely the reason why they had ended whatever they used to have. Stiles didn’t exactly see Gerard waving a rainbow flag and going on a Pride Parade with Chris and Chris’ werewolf boyfriend.
“Can you two cut it out?” Stiles groaned annoyed, glaring at both Chris and Peter.
The two men paused in the middle of their foreplay-esque bickering and stared at him in surprise. Stiles was fairly sure they didn’t even realize what they were doing, that their ‘I want to bite your head off’ had turned into ‘I want to bite you (sexually)’.
“What do you mean?” Chris asked, looking up at him.
“We’re merely discussing the most likely suspect,” Peter added on, eyebrows furrowed.
Stiles stared dumbly at them. Were they serious? So not only did they not notice the sexual tension between them, they didn’t even notice the biting words and fighting? Sighing, Stiles ran his fingers through his hair and shook his head. Would this get better or worse if those two fucked…?
“You two practically bite each other’s head off verbally at all times,” Stiles heaved a sigh. “I’m not sure if it’d help or make matters worse if you fucked about it, but at this point, as the poor, innocent and uninvolved party somehow stuck in the middle of this, I say, please give it a try.”
Both men stared at him in surprise. Rolling his eyes, Stiles returned his attention to his reading. Letting them stew in that. When it remained suspiciously quiet for a long time, Stiles looked up. They were still both staring at him the exact same way, like they were frozen.
“Oh, come on,” Stiles snorted and made a show of rolling his eyes. “The rest of the pack may not have noticed, because they spend a bare minimum of time with the both of you in the same room, but I am stuck here with nobody else but you two, multiple times a week. I notice the… tension between you two. Now, I assumed it was just general ‘I wanna murder you’ vibes, but… the longer we’re working together, the more that changed into ‘I wanna fuck you’ vibes. Though I am very convinced it’s still a bit of the former too. But how kinky you get in bed is your business.”
Chris cleared his throat, looking somewhat flustered and avoiding Stiles’ gaze. “So… you noticed.”
“Again, super hard to miss when one spends as much time one on one on one with both of you,” Stiles raised both his eyebrows pointedly. “I don’t know what is keeping you from continuing where you left off – egos, trauma, self-loathing, overall angst on what your respective daughter may think – I also don’t think I want to know, or should know. But I am very invested in reducing my Chris-and-Peter-induced migraines. If fucking about it will reduce the growling, snarling and barking that you both do? Please, I am begging you to fuck.”
/break\
“’I am begging you to fuck’, he said,” Peter huffed as he collapsed onto his bed. “So close to what I wanted to hear him beg for, just one little two letter word missing.”
Chris snorted and rolled over onto his back. “And somehow, he manages to say something I never expected him to say. Then again, he does excel at that.”
Peter chuckled and scooted closer, until he could rest his head on Chris’ shoulder. It was a calm and serene moment, the kind Chris and Peter hadn’t shared with each other in nearly two decades. Peter rested a hand on Chris’ chest, gently tracing tattoos he remembered Chris getting – some of them on a dare, others just to be contrary to his father. His handsome rebellious hunter. Chris had only complied and obeyed Gerard when Gerard went after Peter’s family. Not… Not that Peter knew that, at the time. He just knew that his father was dead and his boyfriend decided to dump him.
“I never stopped loving you,” Peter whispered, not looking at Chris. “I was… I was so angry, for so long. And then I lost my family and learning that your sister did it…”
“Yeah,” Chris’ voice cracked a little and he wrapped his arm around Peter’s shoulders to pull him close enough to kiss the top of his head. “I never stopped loving you either.”
Peter buried his face in the crook of Chris’ neck and inhaled deeply, before laughing humorlessly. “How is that boy so clever and can solve our issue for us, yet he doesn’t notice that you and I were mostly so… antagonistic toward each other because we’ve noticed each other’s interest in Stiles.”
“I still think you can’t blame me for it,” Chris muttered. “After all that happened when you became Alpha, the deaths and threats, I… I couldn’t trust that you were really better, I thought you would be a danger for that boy, were trying to use him.”
“Oh, because you, with your holier-than-thou hunter attitude, threatening him and the sorry excuse of a pack that existed at the time and being the one to kidnap the two pups he cared about? You were a better choice for him?” Peter asked, lifting his head to show his incredulity.
Chris remained quiet, which was all the confirmation Peter needed to settle down again. They had both met Stiles under less than stellar circumstances and they had both fallen for the boy, leading to them looking at the other as a threat to Stiles. So even while they started getting along more and reigniting old, long since buried feelings, they kept fighting over Stiles.
“What do we do now, wolf?” Chris asked, nosing along Peter’s temple.
“Well, this is… not exactly resolved yet,” Peter motioned between them both. “A lot happened, many years passed and we both changed. We may still love each other and we definitely still work very well together in bed… well, also outside the bed, I have to admit what warmed me up to you again was working together with you and Stiles to protect our territory. But… we have a lot to work through still, don’t we, Christopher?”
“Absolutely,” Chris nodded, his fingers running along Peter’s arm. “We’re a work in progress, but at least we took the first step. But I wasn’t talking about us. I meant the clever pretty boy we both got our eyes on. What are we going to do about him.”
“Mh…” Peter tilted his head thoughtfully. “Now that we are on the same page, perhaps we could pursue him together. But I do think that before we do that, we have to solve some of our issues first. Clearly, our fighting and tension have negatively affected him already, he deserves better than to be romantically dragged into our mess.”
After a moment, Chris nodded. “You’re right. He was really agitated when he yelled at us. It wouldn’t be fair to him to try and get him involved while you and I are still… dysfunctional.”
“Nicely put, dear,” Peter drawled sarcastically, but he smiled a little. “We agree, then.”
Chris grabbed him by the neck and pulled him into a slow, deep kiss. “We agree.”
/break\
Mh. Stiles had made a miscalculation. When he had told Chris and Peter to fuck it out, he had… not accounted for how it would make him feel seeing them fall in love and get gentler around each other. There was a weird ache in his chest every time they smiled at each other, their touches lingered, or worse yet when they kissed. Somehow, somewhere along the way, Stiles may have developed feelings for them both. Both. Not even just one dangerous, emotionally constipated older guy, no, two. Because why would Stiles ever do anything the easy way?
“You smell sour, sweetheart,” Peter pointed out, his fingers curling around Stiles’ neck.
Without meaning to, Stiles relaxed into the touch. It was so nice when a wolf siphoned his pain. And even without major injuries, something somewhere always hurt. Perks of running with wolves and also of being a curious, greedy Spark who pushed himself too far too often. He just wanted to finally be really useful. So far, his magic was mostly protective. He wanted to do more.
“You push yourself too hard, doll,” Chris noted with furrowed brows, looking at the black veins snaking up Peter’s arm. “You need to rest and take care of yourself.”
Stiles hummed noncommittally, knowing directly lying to either of them wouldn’t work anyway. Closing his eyes, he enjoyed the feeling for another moment before pushing off. He grabbed a glass of water and then returned back to the couch that, at this point, had a Stiles-shaped dent from all the research they did there. Both Chris and Peter followed him and sat down on either side of them. Maybe the Stiles-shaped dent needed to be moved, because now that Chris and Peter were actually officially dating, they didn’t need Stiles to physically separate them and keep the peace.
“I nearly had it last night,” Stiles muttered with a frown. “I know my Spark relates to lightning, I should be able to summon and control storms with ease but all it does is… fry the electrics in the house. Dad is currently not talking to me because I killed the coffee maker.”
Chris chuckled and rested a hand on Stiles’ thigh. It sent a shudder down Stiles’ back, because urgh, he wanted them to touch him so badly, but not like this. Not drawing his pain out of pack obligation, not friendly, reassuring pats to make him feel better.
“How about we go to the store and buy a new coffee maker, before dropping you off at home?”
Stiles shot Peter a look. Them being so nice to him was not helping his stupid crush any. Besides, it was already bad enough that he had to rely on them to drive him home because Roscoe was in the shop, again. Turned out chasing a pack of manticores through the preserve was not the best idea because they had claws and stingers that could pierce poor, unsuspecting Jeeps. Chris and Peter had easily offered driving him around, Chris drove him to school and picked him up, claiming it was on the way when he drove Allison anyway. This was all super not helping him get over his growing feelings for them, which was a problem, especially considering how often they worked together! But they were both so competent, strong, thoughtful and badass. He had a type.
/break\
Chris smiled softly as he watched Stiles curl together on the couch in the loft. It was getting late – well, no, it was getting early – and they had been at it for hours. Part of Chris loved when Stiles got so tired, his walls went down and he got soft. Chris felt privileged to be one of the few people who got to see Stiles that way. The bigger part of Chris hated that Stiles worked himself to the bone like that though. The boy should be allowed to focus on school, friends and stupid parties or video games or whatever kids these days did, instead of being forced to grow up so quickly.
“Someone is all tuckered out,” Peter teased as he pulled a blanket up to Stiles’ shoulders.
“Shut up, Idiot Wolf,” Stiles grumbled and jerked up. “I’m awake. I’m totally awake.”
“You’re exhausted, is what you are,” Chris pointed out, removing the book from Stiles’ hands. “And, quite honestly, so am I. It’s time we call it a night.”
“Food and a movie to unwind,” Peter declared, after a quick look at Stiles.
Chris ran his eyes down their boy and nodded his agreement. Stiles was too tightly wound to actually sleep, and he definitely needed to eat something. Smiling, Chris pulled Peter in to kiss him briefly before the wolf headed to the kitchen to make a quick dinner for them.
“Dinner and a movie. Feels like I should head out and leave you to date night,” Stiles huffed.
“No, we’d rather have you here with us, sweetheart,” Peter called out. “As I said, you need food, and you definitely need to unwind. If we let you go home now, you’ll just continue our research.”
“Oh, great, so I’m interrupting date night by making you babysit me,” Stiles snarked dryly.
It was impulsive of him, very unlike Chris, really, but in that moment, as Stiles glowered so petulantly, while the scent of Peter’s garlic-tomato sauce started to fill the loft, with Stiles’ defensiveness about Chris and Peter’s relationship, Chris knew it was time. Things between them had settled, it was hard to pinpoint the exact moment they would have been ready, but in that moment, Chris decided it would be now. It was time that clever boy became theirs.
“As much as I’d love to call you ‘baby’, it definitely has nothing to do with wanting to babysit you,” Chris said, cupping Stiles’ neck and bringing him closer. “How about you stick around, and it’s still date night? But instead of just Peter and me, it’s all three of us? Would you like that, baby?”
Stiles’ breath hitched and his cheeks turned dark-red at the pet-name, making Chris smirk pleased. Big doe-eyes darted over to the kitchen for a moment, just in time for Peter to march out of the kitchen, wearing his apron and scowling at Chris, which only had Stiles tense.
“I thought we would talk about it first, before making any claims, Christopher,” Peter huffed. “I would have preferred making our pitch to Stiles while I’m not wearing the pink Beast in the Kitchen apron Erica bought for me. Darling, relax. You’re not in trouble. Chris and I both like you very much. In fact… We have liked you longer than we have rekindled things between us. The growling that you complained about when you told us to figure our things out was about wanting you, competing for your attention and trying to protect you from each other.”
“...Huh,” Stiles blinked doe-eyed. “Okay. I… will need more brain-power to digest that. Can we just… kiss, for now, and eat dinner and watch that movie…?”
Chris gladly obliged that request. He also gladly watched Peter oblige. Finally, Stiles was theirs.
