Peter Parker X Stiles, Stiles is the son of Tony Stark, Stony is a big part of this, skip if you don't like <3
(pic on the top was me sketching ideas for Stiles' suit because I couldn't imagine it right for the life of me)

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

Stiles Stark was ten years old when his father got kidnapped after a missile from his own company hit him. It was the longest four months of his life, he was being taken care of by his dad's driver/best friend Happy and his assistant Pepper. He loved them both, but he missed his dad every minute he was away from him. When Tony came back and became Iron Man, Stiles had never been more proud, but the new status brought complications to their little family.

In the next two years after Tony Stark became Iron Man, his son was in constant danger, bad people would use him to get to his father. Tony always took care of his son, and later when he met Steve Rogers and they started dating, they would both do everything in their power to save him from hundreds of situations and threats. It got so bad that Tony had to make the hardest decision of his life, he didn't want to be separated from his son again, but he was terrified that one day he wouldn't make it in time and something would happen to Stiles.

"Dad I don't get it, why are you sending me away? Did I do something wrong? Am I getting in the way of you and Steve? Because I swear I'll stop whatever it is, I love Steve, I don't want you guys to break up, but I don't wanna leave home either. Whatever you want me to do, I will just please don't-" a twelve year old Stiles was pulled into a bone crushing hug by his father, cutting off the rest of his sentence, and his breathing. "You did absolutely nothing wrong Sti, Steve loves you and you are in no way getting between us" he reassured his son before pulling away and sitting him down on the couch so they could be at the same eye level as they talked.

"I'm not sending you away because of anything you did, or because you're in the way of anything. I love you more than anything in this world and I would never do this as a punishment or to hurt you in any way. This is all my fault, ever since I became Iron Man people have been coming after you, you've been kidnapped so many times I've lost count. We've always been there to save you, but I'm terrified that one of these days I'm not gonna make it in time. I can't risk anything happening to you, I would never forgive myself if I lost you because of this. I promise this isn't forever, I just want you to stay with my cousin for a while. You can live a normal life, away from the fame and more importantly, the danger that comes with being my son. When you're old enough, and only if you want, you can start training with Shield or with us and learn to protect yourself, but for now you need to go."

Tony wiped a tear off of his son's cheek and pulled him into another hug, "I understand Dad, but you have to promise you'll call me almost every day and that you'll still come visit when you can." Stiles replied determinedly, making a small smile appear on his father's face "I'll call everyday until you get sick of me, and I'll bring you out here to visit whenever you have time off from school. I can't come to you in case someone follows me and figures out where you are." Stiles nodded in agreement, then furrowed his eyebrows in curiosity, "Where am I going?" he asked. "You're going to live with my cousin Noah, he's a sheriff so he can protect you in case something happens. He lives in Beacon Hills, California"

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

Stiles moved to Beacon Hills and made quick friends with another boy named Scott McCall, they became like brothers in a short time. The only secret ever kept between them was Stiles' real name and who his father was, in this town he became Stiles Stilinski, nephew to Noah Stilinski who adopted him after his parents died. He wanted to tell Scott the truth at first, but he knew he could never tell anyone. It got easier for Stiles to hide after three years of living in Beacon, he kept in contact with his dad but didn't get to see him for longer than a week or two at a time, and that was only a few times a year, but they talked on the phone constantly.

After Stiles' last day of freshman year, he got home and collapsed on his bed in exhaustion, he finally had a whole three months to relax without homework or studying. He smiled when his phone rang, knowing who it would be and not being surprised in the slightest when he saw the caller ID. "hey Dad!" he said as he answered "hey kiddo, how was your last day of school?" he smiled softly at the sound of his dad's voice, noting the excitement in it but choosing not to ask about it yet, "it was great, I passed all my classes with straight A's and me and Scott made plans for the next couple days, he finally agreed to watch all the Star Wars movies with me. I think he's just sick of me talking about them and not understanding anything I say" they both laughed at that, though Stiles stopped as he heard a third voice whispering "just tell him already" making him confused.

"Tell me what? Was that Steve? Oh my God, are you guys finally engaged?!" He heard his dad groan and the beep of a button being pushed, no doubt putting him on speaker, "hey kid, I miss you, and no we are somehow not engaged yet" Steve replied with obvious fake annoyance in his tone. "Great now there's two of you" Tony replied, exasperated, making them both laugh "I miss you too Steve, now if the news isn't that I can finally call you Dad too, then what is it? Everyone's okay, right?" he asked, worried. "Everyone is fine kid, and we've both told you several times that you can call him whatever you want, you're the only one arguing against it. You keep saying it's not right until we're officially married, you and I both know you're just being stubborn so I propose sooner. Either way, that's not what I called to talk about. How do you feel about cancelling those plans with Scott?"

"I don't know I was really looking forward to making him watch Star... hold on, why would I have to cancel them?" he could feel a smile forming as an idea popped into his head about what this could be about, but he tried not to get his hopes up in case he was wrong, "well we were kind of hoping you would want to spend the summer in New York with us, maybe start the training we've been talking about now that you're fifteen, but if watching those movies with Scott is more important then-" "NO!" he cut his dad off, making the two on the other end of the phone laugh "I'll start packing right now, I'll tell Scott I'm spending the summer with other extended family or at camp or something, I don't know and I don't care, I'll figure out an excuse. I can't wait to see you guys and spend a whole three months there!"

All Stiles knew was that he wanted to spend as much time as possible with his dad(s) and getting to know the rest of the people living at the compound, he had no idea that making the decision to train this summer would change the course of his life forever. He took to training easily, learning hundreds of new moves and training techniques faster than anyone the Avengers had ever seen before. Natasha taught him hand to hand combat, Clint taught him how to aim and use different weapons and Steve taught him how to use his strength and size to his advantage, using techniques he learned in the army before he took the super soldier serum. Stiles and his dad spent long hours in the lab designing some things he could use if he joined on any missions, the teenager didn't want a whole Iron Man suit because he wanted to make his own identity as a hero, so instead they compromised.

He got to ride a motorcycle instead of flying, and he got to wear a kick ass outfit, black jeans and t-shirt, black and purple leather jacket with black combat boots. He helped his dad design him a helmet to hide his identity, though it looked more like a motorcycle helmet, it had all the capabilities of the regular Iron suit's helmet, AI included, it looked like nothing more than a black circle behind his ear normally, then it transforms into a helmet when he double taps. He also started working on a gauntlet type thing that goes almost to his elbow, the sleeve has a built in computer so he can put his hacking skills to use (also taught by his dad over the summer), he also didn't like the idea of blueprints or other important documents clouding his vision from his helmet so most of those features, along with non verbal communication features ended up in the gauntlet.

(He can hear the teams comms and phone calls from his helmet, he can also ask his AI to answer calls verbally, but he can answer/receive texts and emails on his mini-computer and he can use it as a phone if he doesn't have the helmet on)

Same outfit and helmet but the gauntlet is shorter, more like a long glove than a robotic arm (thanks AI)

Those were the only people he met in the first month as Thor was off world and Bruce was on vacation. Though at the start of the second month, he walked into the kitchen and saw one of the people he was the most excited to meet standing with the rest, his loud gasp alerted everyone to his presence but he only looked at one person. "Oh my God! It's you! I can't believe it took me so long to meet you, you're-" he was cut off by a slightly annoyed voice "yeah I know, I know I'm the Hul-" "You're Doctor Bruce Banner!" he continued excitedly, ignoring the interruption as if it never happened and not noticing the shocked expression.

"I've read your thesis on biochemistry and all of your research on nuclear physics like a thousand times! I would love to pick your brain if you have the time, I have a million questions for you about your work in gamma radiation, this is so cool, I didn't know if I would get to meet you this summer!" Everyone stared at him with open mouths for a few seconds, then turned to Tony "are you guys really surprised? He is my son." he said with an arm extended towards him "I don't care whose son he is, he's my favourite now. Kid, you're like the first person who has ever recognised me as a scientist rather than the other thing, we can talk about whatever you want for however long you want, I don't care how busy I am"

Bruce was the first to coin Stiles as his favourite, but definitely not the last. He quickly stole the hearts of everyone in the compound in the three months he spent there, and they all became his honorary aunts and uncles. It was hard for all of them when he had to go back at the end of his break, but he gave them all his contact information and promised to keep in touch as much as he could between school work. He had no idea how much his life would change when classes started again, he should have known that with everything he's seen in his life, it was more than likely werewolves existed too.

The next nine months for him were filled with insane adventures and even more insane people and creatures, but come the end of his sophomore year, he was more than ready to go back to his training and see his family. His abilities increased exponentially with all the dangers he fought in Beacon Hills, so did his instincts. He only trained for another few weeks in New York before they told him he was coming on a mission with them, he couldn't get his gear on faster after that. It was a standard mission, taking down some hydra agents and recovering stolen SHIELD equipment from them, though he was told another hero was most likely going to join them as he'd been showing up whenever any sort of crime happened and helping out, whether he was asked to or not. That made Stiles laugh quietly, excited to meet this other guy that no one would tell him the name of just to mess with him, using his curiosity to annoy him.

As Stiles was in the middle of fighting three guys off at once, he saw another figure come towards him...swinging? The other guy helped him fight off a fourth hydra agent coming from behind him as he took down his opponents "Thanks Spidey" he called out as he recognised the hero from YouTube, the only reply he got was a two-finger salute as they both went back to fighting. When all the agents were down and the tech was recovered, Stiles went up to the new guy so he could introduce himself "Hey man, I'm Mischief. I'm new, well sort of" he let out a little laugh as he put his hand out, the other man accepted the handshake "I'm Spiderman, but seems like you already knew that"

Stiles was shocked at the sound of his voice, he sounded young, closer to his own age "Are you a teenager?" he couldn't help but ask, regretting it when the eyes on the suit grew larger as if his own widened in panic "relax, so am I" Spidey let out a sigh of relief, deciding to try and make a new superhero friend that was his age "Yeah I'm seventeen, sorry I just don't normally like to let other people know that because they start to think I'm incapable of doing this job" Stiles let a small smile slip under his helmet "I get that, I'm sixteen. These guys are pretty great though, at least when they're not stealing my Pop-Tarts"

"That was one time! Get over it!" he rolled his eyes at the yell coming from afar, Clint no doubt hearing him from the comms but thinking it necessary to scream from over the hill in answer, so he decided to yell back "It's been three times this week alone! Who are you lying to right now!?" he shook his head as all he heard back were mumbles coming from the speaker in his suit "Binks can you mute my mic on communications and let everyone know it's rude to listen to people's conversations" he said to the AI in his helmet, getting a verbal confirmation back before returning to his conversation.

"Binks? Like the Jar Jar Binks from Star Wars?" Spiderman asked him, clear joy in his voice "Yeah he's the AI in my helmet, I took some code from Iron Man's Jarvis to make him so I thought you know: Jarvis- Jar Jar, but I didn't want to say all that so I settled for Binks. You like Star Wars?" he asked excited that someone understood his reference "I love Star Wars! I just finished building a Lego death star with my best friend!" Stiles' grin was so big it almost hurt his face, he could finally talk about the movies with someone "That's so cool! My best friend still refuses to watch them...do you maybe want to go back to the Avengers compound with us? We can have a Star Wars marathon and get to know each other more?" he asked, trying and failing to keep the hope out of his tone. He needed friends that actually knew about this side of his life.

"I'd love to, I just have to let my Aunt know I'll be home late!" Spidey replied, equally as excited. Stiles turned his comms back on to ask permission and smiled when he got it, though a little reluctantly from his dad. they cleaned up the damage from their mission and went back to the compound together, Stiles and the newcomer going up to the residential floor while the rest had to go in for a debrief. As they reached the young Stark's room, he pressed a button on his mini computer and his helmet retracted back to its little device, he ran a hand through his unruly hair to tame it and started speaking, still turned away from the other teenager "don't feel pressured to take your mask off too, its just not exactly comfortable to relax and watch a movie in a motorcycle helmet"

They both laughed at his comment as he took off his jacket and threw it at his desk chair "No it's okay, we're supposed to be getting to know each other, might as well start with what we look like" Stiles turned around at the sound of fabric moving, stopping in his tracks as he caught sight of just what the other boy looked like outside of his suit and in normal clothing...he was gorgeous. "Umm I-I'm Stiles by the way" he stuttered through the introduction, cursing himself internally for letting his nerves get the best of him, if he hadn't had his bi awakening at a much younger age, he definitely would have now. "I'm Peter, Peter Parker. Are-are you Mr.Stark's son? You haven't been in the tabloids for a while but I could recognise you anywhere?" Stiles raised an eyebrow at that.

"Oh really? And why is that? I mean I am his son, but why could you recognise me anywhere?" he asked, slightly mocking Peter's words, revelling in the way the other boy immediately turned pink "Uh-I-Um did I say that? I don't think I did-must have heard wrong or-or something" he rambled nervously, rubbing the back of his neck "No, you definitely said that. Tell me Spidey, promise I won't make fun of you" he teased, enjoying the way he could make someone this cute, so flustered "Well um- when I was thirteen you had this paparazzi picture taken of you outside of this restaurant or something and you looked really good in it because you were wearing a suit, not that you don't look good right now in a T-shirt and jeans black is definitely your colour, but you just looked really good in that picture, not that I still think you look good in that picture obviously, not that I think you look bad but I'm seventeen, so I'm not really looking at a picture of a twelve year old in a suit and thinking 'oh hey he looks good' but at the time I was only thirteen and that picture was really good and you were kind of the reason I realised I liked guys back then. oh my God please ignore everything I just said, this is literally the first conversation I've ever had with you and this is so embarrassing oh my God I-" "PETER BREATHE!"

The young hero took a long breath at the suggestion and hid his burning hot face in his hands when he heard a short laugh escape from across the room "So what I got from that was, I was your first bi panic and you think I look good in my t-shirt and jeans." He repeated, slightly smugly and definitely flirtatiously, laughing louder when all he got in response was a groan and Peter nodding his head where it was still buried in his palms.

"fuck, you're so cute" he replied with a smile, making sure his voice was sincere as he knew it kind of sounded condescending even though it was a genuine observation. Thankfully, Peter just looked up with a smile, face still red as a tomato. "Come on, let's go watch the movies. Oh and if it makes you feel any better, this is our second conversation, not our first so you don't have to be too embarrassed" he smirked at the eye roll shot his way, walking past Peter and stopping when he was right at his side, putting an arm on his shoulder "For the record, I think you look great in your t-shirt and jeans too"

It only took them two weeks of getting to know each other and becoming friends to kiss for the first time, they knew they didn't have long before Stiles had to go back to California and they couldn't contain their obvious attraction to each other. They spent the next few weeks in the honeymoon phase of their new relationship, Peter still getting nervous around all the Avengers because of their protectiveness over their favourite team member. Stiles was scared of what would happen to them when he went back to school, but they still talked daily and any time they saw each other during breaks from school, it would be like they had spent no time apart.

Before either of them knew it, a year had passed and Stiles was going back to Beacon Hills for his senior year after another three months at the compound. They celebrated their anniversary and then said goodbye once again, knowing they would see each other again in a few months for Christmas break but still spending the entirety of their last few days together in each others arms. Though their sadness was quickly overshadowed by extreme joy when Tony and Steve announced their engagement two days before Stiles' flight. He was so excited he jumped into both of their arms and had to hold back tears as he hugged them, Steve had always been like a dad to him since they met but he was so excited to make it more official.

"Now that you guys finally took the hint, I can stop being stubborn. Steve how would you feel if I started to call you dad now, or maybe pops" Steve smirked at him "You already call me both of those things" he told him with a raised eyebrow "Yeah but that's only when I'm tired, or injured, or random slip ups, basically any time that my brain forgets that I'm trying to make a point and get you guys married faster so it just runs on instinct and calls you how I've seen you for years. How would you feel if I started always calling you that..you know on purpose now" he smiled, filing away the tears in Steve's eyes so he could make fun of him for it at a later date, like he didn't already know he's seen him as a second dad since he was like thirteen. "I'd love it kiddo" "great because I just changed your name in my phone" he held up the proof and walked away smiling.

No one but him and his boyfriend had to know that he only changed it from 'basically Dad #2" to just "Dad #2". He waited until he was alone in his room with Peter to let his own tears fall, he was so happy for them, and for himself, he could finally call Steve 'Dad' instead of stopping himself every time. He was already his other father, marriage or not, but he wanted to continue being petty as long as possible until one of them finally popped the question. Though knowing his dads, they probably waited so long just so they could be equally as petty back. His boyfriend just pulled him down so they could lay cuddled together as he let his emotions out.

They all celebrated properly when Stiles came back for Christmas break, talking about their plans for a small ceremony, with only close friends. They would wait until After Stiles graduated and would be living with them full time, the teenager also talked about his plans to apply to NYU so he could live in the city with them. Peter couldn't wait until Stiles graduated and joined him in university, they would never have to spend another day apart. Their love never diminished for a second while they were apart, but they still missed each other every second of every day in the months where Stiles was back in school in California.

Stiles had been gone over a month after New Years when Peter got a new mission, normally he hated missions where he would have to leave the city because he had to transfer all his classes to online learning and he would be away from his friends for a long period of time, but when he learned the location of this one, he couldn't bring himself to be upset. He didn't tell Stiles about this new mission like he normally did, he wanted it to be a surprise.

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

Stiles was sitting with Scott on a picnic table outside School, waiting for the girls to join them and wondering what was taking them so long. He got his answer when they rushed back to the table squealing "Oh my God, and did you see his arms? He looks nerdy but those muscles!!!" he laughed at Lydia's excited ranting "I know! And his hair!" Allison joined in, sending an apologetic look at Scott when he looked slightly offended that his girlfriend was fawning over another guy "Who are you guys talking about?" Stiles couldn't help but ask, he had never seen them act this taken by someone at their school, especially since they were both in great relationships.

"There's a new kid, he just transferred in and he is so cute. Oh my God Stiles!-" he groaned before she could even continue, already knowing where she was going with this "Don't start plea-" she continued, pretending she didn't hear him "You should totally go talk to him, he's definitely your type. He's cute and nerdy, definitely smart judging by the way he answered some of the questions in class, and he's probably ripped if his arms are any indication of what's under that baggy shirt" Malia laughed as she sat down with them, having heard her girlfriend's entire conversation as she was walking up, kissing her cheek and not commenting on the situation.

"I don't care how good you think he looks or how much he's my type, I'm not interested." he replied, already annoyed at the conversation as he took a bite of his apple, "Hey babe. Come on Stiles! You won't even give him a chance? You haven't seen what he looks like!" he hoped the arrival of her girlfriend would deter Lydia from her comments but he should have known better "It doesn't matter what he looks like, my decision won't change. Even if you never believe me Lyds, I've told you a hundred times I have a boyfriend, you need to stop trying to set me up." he repeated the same argument he always gave her, not noticing the new kid walking up to them.

"I never said I didn't believe you, but come on you say he lives in another state, we've never met him and you've never even told us about him. All you say is that you have a boyfriend whose name is Peter, nothing else" she tells him, he rolls his eyes and lets out a sigh, a fond look taking over his face "If knowing more about him is what gets you to back off, I'll tell you. He is the dumbest, most adorable, clumsy idiot I have ever met while somehow also being one of the smartest people I know. The day I met him, I felt like I could finally breathe, like something had been stopping me from getting oxygen. It felt likely I was drowning my whole like and he pulled me up, he gave me a reason to swim to the surface and take a deep breath. His eyes are brown and he thinks they're boring, but I have never seen any eyes, blue, green, grey, or any other colour you could think of as beautiful as his. His eyes are probably one of my favourite things about him to be honest, not that he believes me. What he doesn't realise is why, looking into them, getting lost in them is like nothing I've ever felt before and I know I'm going to do everything in my power to make sure that they are the last things I look into before I got to sleep and the first things I see when I wake up for the rest of my life. Because I see our future in them, I see and feel home in them. He is my home, he's my soulmate, my best friend, and the love of my life all rolled into one and I can't imagine my life without him."

Stiles wipes a few tears off his cheeks, thinking about how much he misses his boyfriend, He doesn't notice that the strawberry blonde wasn't even looking at him and the rest of his friends followed her gaze. They were all staring at the new kid in confusion, he had a fond look on his face and his own tears streaming down his cheeks after standing there and listening to the whole speech silently. Stiles decides to deflect with some humour to stop himself from thinking of his boyfriend until he gets home so he can FaceTime him "He's also like really fucking hot, so there's that too" he laughs but it's cut short as he realises no one is looking at him, then he feels someone stand closer to the bench, behind him. "You're not so bad yourself baby"

"Peter!" he yelled as he jumped into his arms, his boyfriend easily catching him with his super strength and pulling him into a deep kiss. They smiled against each other's lips before pulling away "Did you mean all of that?" the young hero couldn't help but ask, tears still shining in his eyes at the amount of love he felt for the boy in his arms "every word, sweetheart" Peter didn't hesitate to pull his boyfriend into another kiss, putting all his emotions into it, but it still wasn't enough. He put Stiles down, keeping one hand on his waist and the other on his face, sweeping his thumb across his cheekbone.

"I'm not nearly as good with my words as you are, but I don't even have to try when you're the one I'm talking about. Sti you are the best thing to ever happen to me, this last year and a half has brought me more happiness than I ever thought I could have, or even deserve for that matter. You said you were going to do whatever you could to make sure you had me for the rest of your life, Baby don't you know that you being you is all I will ever need. Keep looking at me with that smile on your face, keep talking to me with that soft tone you use when you're tired and you're barely paying attention to what's coming out of your mouth, keep being the amazing, sweet, compassionate, sassy, sarcastic and gorgeous guy I fell in love with and you will never lose me. Seeing my Aunt and Uncle together showed me what soulmates looked like, but meeting you showed me what having a soulmate felt like. You flirted with me until my face felt so hot I thought it would melt off and then we sat on a couch, watched Star Wars and talked for hours, I think I fell in love with you right then and there and I haven't looked back since. I've always thought you were attractive, but your smile and your passion when you went on a twenty minute rant about how conflicted you were about Anakin and Padme's relationship because of how they met, but you couldn't help liking them after watching Clone Wars, that's what got me. I knew I could listen to you rant for the rest of my life and never complain once, my heart has belonged to you since that night and I wouldn't want it any other way. I love you more than I could ever put into words baby."

They were both crying by the end of the speech "I think you definitely came pretty close to putting it into words, that was beautiful. I love you too." they connected their lips once again, oblivious to anything and everything around them, all that mattered in that moment was the feeling of safety they always got the second they were together. They pulled away from each other awkwardly when they heard a throat being cleared from the table behind Stiles. "So you know the new kid" Lydia said, a smug look on her face "I guess you were right Lyds, he is definitely my type. I told you my boyfriend was hot as fuck" he replied with a smirk, introducing his friends to the love of his life, gaining comfort in knowing this was the first and last time he would have to introduce someone he was dating to his closest friends. There would never be anyone else to introduce. Peter Parker was his beginning, his middle, and his end, he would love him until his last breath.

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

A/N: I was going to make this longer, adding the reason Peter was there for his mission and having them fight the thing together, getting the pack to join for help and then realising they need more reinforcements and bringing in the Avengers to help. then stiles realises that he actually has enough credits to graduate early and going back to NY with them but its 6am, I have class in a few hours, and this is already super long (5500 words).

PLEASE READ!

A/N: how did you guys like this style of writing instead? I usually suck at dialogue but I tried to incorporate it much more in this oneshot. also I know I focused much more on the family dynamics and Stiles with the Avengers instead of the relationship but I hope the big speeches at the end compensated for that. ok I love you guys, lmk if you liked this one and if you prefer the dialogue heavy more than my usual style.
