You and Peter were on your way to the compound, your nerves making the drive feel like an eternity. Peter was gripping the steering wheel, his knuckles white with anxiety.
"I'm telling you, he's gonna kill me," Peter said, his voice trembling. "He'll blast me off Earth, and I'll never see my kid."
"Peter, stop being such a drama queen," you said, trying to keep the mood light. "Dad loves you."
"I'm serious, babe!" Peter's eyes darted around the road as if he was expecting an Avengers-level attack at any moment. "He won't be happy that I made his daughter pregnant."
"Peter, we're married," you reminded him with a teasing smile.
"I KNOW!" Peter practically shouted, his stress palpable. "But it's Tony Stark we're talking about! He's a genius billionaire with a high-tech suit. I don't even have a suit like him!"
You chuckled, reaching over to squeeze his hand. "Relax. It's going to be fine. Besides, you're not just telling him you're going to be a dad-you're giving him a grandkid. He'll love it."
Peter gulped. "I hope so."
As you pulled into the compound's driveway, you could see Tony's birthday party in full swing. The decorations were up, and everyone was mingling. Tony, Pepper, and Morgan were surrounded by the Avengers, with Happy looking over the festivities with his usual vigilance.
You and Peter walked in, and Morgan immediately ran over to hug you. "Y/n!" She squealed, her excitement almost palpable.
"Hey, Morgan!" You replied, giving her a big hug. "Happy birthday to Dad, huh?"
"Yeah!" Morgan nodded vigorously.
Peter was fidgeting beside you, eyes darting around nervously.
"Pete, you look like you're about to face Thanos again," Tony joked, noticing Peter's nervousness as he walked over to greet you both.
"Just a little gift, happy birthday, dad," you said, trying to sound casual.
"Oh, honey, you didn't have to but you know I love gifts."
You chuckled.

Dinner was served, and despite the delicious food and lively conversation, Peter couldn't seem to relax. He kept playing with his fork and glancing at the clock, as if hoping time would slow down or speed up.
Finally, it was time for the presents. You exchanged knowing glances with Peter and headed over to where Tony was opening gifts.
"Alright, let's see what we've got here," Tony said, grabbing your gift first, tearing into the wrapping paper with his usual flair. When he pulled out the onesie with "The Best Grandpa's Grandkid" printed on it, his face registered confusion for a moment.
Everyone else was busy chatting with each other, but you watched Tony's reaction closely. As the realization hit, his eyes widened, and a huge smile spread across his face.
"This is... this is..." Tony started, his voice cracking slightly with emotion. "I'm going to be a grandpa?" Everyone's attention was on you and Tony now.
"Happy Birthday, dad."
All the avengers started congratulating you. Natasha was the first to approach you. She enveloped you in a warm hug. "You're going to be the best mom," she said with a sincere smile.
Wanda joined in, her own hug equally comforting. "Absolutely. You and Peter are going to be amazing parents."
You felt a lump in your throat as their kindness washed over you. "Thank you, guys. It means a lot."
Pepper smiled at the display of support and stepped over to you, her eyes glistening slightly. She kissed your forehead gently. "Oh, honey, you grew up so fast."
Sam and Bucky, who had been watching the whole interaction with smirks on their faces, couldn't resist a bit of teasing. Sam clapped Peter on the back hard and said, "Looks like the kid's having a kid."
Bucky chuckled, adding, "Guess we'll have to start calling you 'Dad' now, Parker."
Peter laughed nervously, his face still a bit pale. "Yeah, I guess so."
Steve approached, giving Peter a reassuring pat on the back. "You'll do great, Pete. You've got this."
Tony looked at you with a mixture of pride and nostalgia. "My little girl is going to be a mom," he said, his voice cracking slightly. "You grew up so fast, Y/n."
He pulled you into a tight embrace, his tears betraying the emotions he was trying to keep in check. "I'm so proud of you," he murmured, kissing your forehead.
As Tony pulled back from the hug, his gaze shifted to Peter. Peter's face went pale. He had a brief moment of relief as he saw Tony's smile, but it quickly turned into a look of terror as Tony's expression shifted.
Tony's eyes narrowed as he turned to Peter, the smile gone. "How dare you make my little girl pregnant!"
"Dad," you said, trying to keep your tone calm, "let's not start with this."
"Um, Tony, sir, I-I can explain," Peter stammered, his face turning red.
"Tony, honey, calm down," Pepper said, stepping in with a soothing voice.
"Oh, I'm calm, Pep," Tony said through gritted teeth. "But Parker's gonna die tonight."
Peter's eyes were wide as he looked to you for help. "Y/n, say something!"
"Dad," you said, stepping in between Tony and Peter. "Do you want your grandchild to be fatherless?"
Tony huffed, looking between you and Peter. "Fine," he grumbled. "But only because I don't want to be a grandpa to a kid without a father. Peter, you better take care of my little girl or so help me-"
"I will!" Peter interrupted, trying to sound as earnest as possible. "I promise, Mr. Stark, I'll do everything I can."
"Dad, relax," you interjected, stepping between Tony and Peter. "Peter's going to be a great dad. He loves me, and he's going to love our baby."
Tony's face softened a little, but his protective instincts were still on high alert. "Alright, alright. Just... make sure you keep my little girl happy. And don't mess this up."
Peter nodded vigorously, his eyes wide. "I promise. I'll do everything I can."
"You better."
Everyone else, who had been watching the scene with a mix of amusement and concern, slowly started to relax as Tony's anger subsided. Morgan ran over to Peter and hugged him tightly.
"You're going to be the best dad ever!" She declared.
Peter looked at Morgan, his eyes misty. "Thanks, kid."
Happy came over and slapped Peter on the back, almost knocking him over. "Welcome to the family, kid. If you need any help with the whole 'being a dad' thing, let me know."
Peter managed a shaky laugh. "I'll definitely keep that in mind."
Pepper wrapped her arms around Tony, giving him a gentle squeeze. "See? It's going to be alright."
Tony took a deep breath, finally letting go of some of his tension. "Yeah, alright. I guess I'm just going to have to get used to this."
The rest of the evening was filled with congratulations and warm wishes. Tony seemed to be in a much better mood as he began to accept the news. The whole party eventually gathered around, with everyone offering their support and excitement.
As the night wound down, you and Peter found a quiet corner of the compound, away from the hustle and bustle of the party.
"See?" You said, wrapping your arms around him. "That wasn't so bad."
Peter let out a sigh of relief. "Yeah, it actually went better than I thought it would."
"Now we just have to get used to the idea of being parents," you said with a smile.
Peter grinned, his anxiety replaced by excitement. "Yeah, I think we can handle that."
You both stood there, imagining the future and the new life that was growing inside you. It was a perfect end to an eventful day, with love, laughter, and a new chapter about to begin.
