"Ok! Are we ready? Steve?" Peter calls.

"Yup! Breakfast is ready! Everyone else in position?" Steve asks.

"Yup! Decorations all set!" Pepper says. Everyone goes into position at the front of the room.

"Great! I'll go wake him up!" Peter says excitedly as he runs to the elevator. It was Tony's birthday and everything was going to be perfect. He and the team planned a small party because they knew he would like it better than a big one.

The elevator dinged and Peter ran into Tony's bedroom.

"Tony! Wake up!" Peter says, shaking him slightly.

"Hmmm."

"Come on! It's your birthday!" Peter insists.

"Mmmm." Tony says, pulling Peter into bed with him.

"Tony! It's time to get up! Come on!" Peter says, pulling Tony up.

"Agh, why? So tired…" Tony says, closing his eyes.

"It's your birthday! Come on! Let's go to the common room!" Peter says discreetly.

"Oh right. That's today." Tony says, his eyes widening.

Peter stops for a second. "You-you forgot? Who forgets their birthday?"

"Trust me, kid. My birthday isn't that important." Tony chuckles.

Peter stops in his tracks. "Why?"

Tony looks down and rubs the sleep out of his eyes. "Well...when you have let the number of people die as I have, you tend to not want to celebrate much."

Peter sits down next to Tony. "Tony. You always tell me that I can't save everyone and that it's ok. Maybe you should start listening to your own advice more. You think about all the people you weren't able to save, but forget about the millions of people that you have."

Tony looks into his son's eyes and sees the endless trust and worship in his eyes. It's too much. Tony doesn't deserve Peter or his trust and love. "You'll understand someday. Someday, you'll understand that I'm not the hero you claim I am." Tony whispers.

Peter sighs. His dad was too modest and self-sacrificing for his own good. "That will never happen. I will never ever stop looking up to you. You are everything I want to be. That is never going to change...dad." Peter adds, reaching up to wrap an arm around Tony.

Damn. Tony didn't deserve this kid. Tony leans his head into Peter's shoulder, trying to blink back the tears.

Peter waits for him. He cards a hand through Tony's hair and occupies himself as Tony gets himself together.

"Let's go to the common room." Peter whispers quietly. Tony nods and gets up to use the bathroom.

He returns and puts an arm around Peter's shoulders.

"What would I do without you?" Tony asks softly.

"Well, you'll always have me." Peter says, looking into Tony's chocolate eyes.

"Not letting you go anytime soon, kid." Tony laughs as they get into the elevator.

.

.

.

"SURPRISE!" everyone shouts as the elevator opens.

"Jesus Christ!" Tony shouts, covering his ears.

"Happy Birthday Tony!" everyone yells as they make their way towards them.

Tony laughs as they all pat him on the back.

"Is all this really necessary?" he asks with a smile.

"Well, your feeding and clothing us so we figured this was the least we could do." Clint jokes.

"Happy Birthday honey." Pepper says, giving Tony a light kiss.

Tony smiles. "Did the one and only Capiscle make me a birthday breakfast?" he asks, raising an eyebrow.

"Enjoy the one time everything is IronMan themed." Steve says, chuckling.

"Yes! Victory!" tony says, pumping a fist in the air.

"Let us eat!" Thor exclaims.

After everyone is stuffed, everyone settles down to give Tony their presents. (Que Tony's complaining)

"Guys! I'm literally a billionaire! I can buy all this stuff!" Tony tells them.

"Hello? It's the thought that counts." Rhodey says rolling his eyes.

"Whatever Sourpatch." Tony says.

"I shall go first!" Thor announces. Tony opens the package to find a small red and gold bracelet with a small red stone that he could easily program into the IronMan suit. Tony raises an eyebrow and looks at Thor.

"If you are ever in need of assistance, press the red stone and I can blast some lightning down from Asgard to help you." Thor explains. Tony nods and thanks him.

"Woah! You can do that!?" Peter asks.

"I'm a God." Thor laughs.

"We get it!" everyone says at the same time.

Tony gets a bunch of cool stuff from the Avengers from funny cards, to a t-shirt with all the Avenger's symbols on them, to Ironman themed accessories. His favorite was Rhodey's, which was a coffee mug that said "Part-time superhero, Full-time Dad", which made Peter blush beet red. Even Loki gave him a dagger necklace with a card that said, "Keep's nightmares away- Loki."

Everyone turns to Peter after they give Tony their gift.

"I think we all want to know what the squirt got for Tony." Clint says, looking at them expectantly.

"Actually, I'm going to give Tony my gift in private, but I'll hopefully tell you tomorrow." Peter says nervously. The team nods.

"Hopefully?" Tony asks, confused.

"Later." Peter whispers, giving Pepper a look.

Tony frowns but nods, and pulls Peter into his chest.

"Thanks everyone. These are all pretty great. Now I intend to enjoy the day where you all have to be nice to me! Someone pick a movie!" Tony announces.

Everyone laughs as they start the Hunger Games.

.

They have a great day of lazing around and doing practically nothing. Tony had to admit it was nice hanging out with the team all day. They watched movies, played Monopoly with real money and other useless games Peter insisted they play. Soon it was nighttime and everyone started turning in early.

After everyone except Peter, Tony and Pepper left, Tony turned to Peter.

"Hey. You seemed kind of off the whole day. What's wrong Pete?" Tony asks.

Pepper got up, patted Peter's back, and turned to Tony.

"I'm going to bed. Peter, I think you should give Tony your gift now." Pepper says with a wide smile.

"Right. Goodnight Pepper." Peter whispers.

"Goodnight Peter, Tony." she says, kissing both their cheeks.

"Goodnight Pep." Tony says and turns to Peter.

"Ok." Peter says, taking a deep breath.

He turns on the couch so they are facing each other, with the envelope behind his back.

Tony looks at him confused, but doesn't say anything.

"After everything that's gone on in the past few months, I've been thinking about how much you truly mean to me. And I mean a lot has gone on. May died, I watched you almost die, I got kidnapped, a lot of stuff. And every passing day I realized that I loved you more and more, but more than that, you loved me. I realized that every time that you freaked out about me going out as Spiderman, or every minor injury you totally overexaggerated was because you loved me." Peter pauses to evaluate the look on Tony's face.

Peter could see the shine in Tony's eyes but he knew if he hugged him that he would never be able to finish his speech.

"I don't think you fully understand how much I appreciate you. I was just a random kid from Queens trying to make a small difference. You didn't have to take me under your wing, but you did. And when May died, you didn't have to take me in, but you did because that's the kind of person you are. It's just you don't let a lot of people see it. What I'm trying to say is that I'm honored to be your son. Every time you call me your kid, it reminds me of all the things you have done for me. And…" Peter trails off as he grabs the first document out of the envelope and hands it to Tony.

"Now, if you're ok with it, I'm even more honored to carry your name. Because I love you dad." Peter finishes. He looks up nervously at Tony and sees Tony's hands shake as he looks at the paper.

He puts it down carefully on the table and puts his arms around Peter. Peter hugs him back with everything he has.

"No one could be more honored than me. I have you for a son." he spring to Peter's eyes as he hugs Tony even tighter.

Tony pulls back and puts both his hands on Peter's face, brushing the brown hair out of Peter's eyes.

"Peter Parker Stark huh?" Tony asks, a tear making its way down Tony's cheek.

"It has a nice ring to it doesn't it?" Peter asks, wiping away the tear.

Tony nods. "God kid. I'm a water fountain." he laughs.

"I'm not done." Peter says, nervous again.

"Jeez. I've had enough crying for one night." Tony jokes.

"Then I'll make it quick." Peter smiles, clearing his throat.

"So you always say that I'm your son. And I already call you dad. I hope you know how much I love you and care for you. And...I was thinking about maybe making it official?" Peter asks, handing Tony the adoption papers with his signature on it.

Tony's eyes widen as he takes the paper from Peter, one hand going to his mouth. He sees Peter's signature on the line and the next thing he knows, he's full out sobbing, clutching Peter.

Peter laughs as he hugs Tony back. "Oh my God. Oh my God." Tony repeats, holding Peter like a lifeline.

"Is that a yes?" Peter asks, laughing.

"I-I just never thought you would actually want me as a-a dad. Of course, it's a yes." Tony says, through his tears.

"You were already my dad Tony. These are just a bunch of papers." Peter tells him.

"Oh my God. Peter your mine. You are my son. Mine. I probably sound like an evil genius right now." Tony laughs, clutching Peter.

"Yeah. Don't worry, it's only a little bit weird." Peter jokes.

"I love you so, so much kid." Tony says, finally getting a hold of himself.

"I love you more." Peter says, laying his head in Tony's lap.

"I love you most. And I always will."

"Should we wake them up?"

"No! They're soo cute!"

"Tony's never going to hear the end of this."

"Yup. This is awesome blackmail material."

"You guys are so mean!"

Tony groans as he starts to wake up. He opens his eyes to find the entire team grinning in front of him. Clint and Natasha are smiling evilly with cameras in their hands.

"Jeez!" Tony yelps.

"Wh'ts goin on?" Peter asks sleepily.

"Awww." Everyone coos.

Peter opens his eyes and looks at everyone.

"Oh, it's just you guys." Peter says, closing his eyes. Then, his brain processes the information.

"Oh my Gosh. What are you guys doing here?" Peter squeaks. Everyone explodes with laughter.

"You guys fell asleep on the couch." Wanda giggles.

"You guys are literally the worst." Tony complains, pulling Peter into his chest.

"So? What was Peter's gift? You guys sleep too long. We've been waiting forever!" Steve complins.

Tony sighs and brings his hand out of the blanket, where the documents were still clutched in his hand. He throws them at the team and closes his eyes again. As everyone reads the documents, they all squeal and wake the duo up again.

"Oh my God! Congratulations!"

"Finally! I thought it would never happen!"

"Wow! Peter Parker Stark! Sounds pretty damn good!"

"Language."

"Shut it Cap."

"Wow! I can't believe it's official!"

"Great! We're stuck with the kid now!"

"Guys! Will you lower the volume?" Peter complains, laughing a bit.

"Ok. Everyone give them some space." Pepper chastises.

Tony rubs the sleep out of his eyes.

"Congrats Tony." Pepper smiles.

Tony grins back. "Hey I officially got a son, but so did you!" Tony tells her.

"Yup. And I plan on spoiling him rotten." Pepper says, ruffling Peter's hair.

(Que the team's cooing behind them)

"Ok. We're going on vacation! And I guess the team could tag along. Everyone pack their bags! We're leaving tomorrow!" Tony says, getting up.

"Yes! Vacation!" Natasha exclaims.

"We need this. Avengers assemble!" Steve jokes.

"Welp, first family vacay kid. Might want to bring your phone." Tony chuckles.

"Ned and MJ are going to freak! Vacation with the Avengers and Tony and Pepper Stark are my parents now!" Peter says, bouncing off toward his room.

"I love that kid." Tony and Pepper say at the same time.
