Bucky is 31 weeks and at home watching the mission the others were on a laptop.
Then he felt a hard kick, winced and put his hand on his stomach.
When it stopped he took a deep breath.
"Calm down buddy. They'll be back in a few days." he said.
Then he kept watching and saw things they would need him for so did what he could mostly to Steve.
For the next few hours he felt it and tried to ignore it but had trouble with it getting worse.
He was ending with one right now and took a deep breath.
"What's got you so active today?" he said rubbing his stomach.
Later while he was asleep he was woken up by pain and held his stomach with his eyes shut tight.
When it stopped he took a few deep breaths and groaned.
"You need to calm down, papa's not home yet and you're to early."
Then he looked at his clock and saw it was 2:30 am.
It had been going on since 9:30 yesterday morning and he was getting worried.
The whole day it had gotten worse and more often than usual.
He laid back down and shut his eyes to feel it go off again and grunted with his eyes tight.
Suddenly he felt himself get wet and opened his eyes when it stopped.
"Oh shit." he said. "It's to early! I can't do it alone!" he said panicking.
Then he slowly got up and grabbed his phone.
"Come on, pick up." he muttered but got the recording. "Tony, I need you to get home! My water just broke and oh God!" he said and felt a strong contraction go off.
When it was done he took deep breaths.
"Please get home. I can't do it alone!" he said and hung up. "FRIDAY?"
"Yes Sergeant Barnes?" FRIDAY said.
"Is anyone here?"
"Ms. Potts is here sir."
"Tell her to come here." he said and felt another contraction go off.
"Ms. Potts has been told sir and shall be here momentarily."
A few minutes later Pepper came in and saw his eyes shut tight.
"Bucky?" she said and waited.
A few seconds later he took a deep breath and looked at her.
"My water broke." he said. "I called Tony but he didn't answer!"
"Alright calm down. Cho is here so go take a shower to clean up and I'll go tell her." she said gently.
He nodded and went to the shower while Pepper told Cho.
Soon they were at MedBay and Cho was looking to see what was going on.
"I can't do anything. You're already 5 percent." Cho said.
"But it's to early!" Bucky said panicking.
"Calm down Bucky, it's the son of a super soldier so I'm sure he'll be fine." Pepper said gently.
"She's right Sergeant Barnes." Cho said.
He knew they were right so nodded.
"Now what?" he asked.
"Now we wait." she said and they nodded and she left.
"It'll be fine Bucky." Pepper said gently and rubbed his hand.
"I'm not ready for this Pepper." he said shaking his head. "Not without Tony."
"I know Bucky."
"He promised to stay with me and be there the day I have him!" he said with tears going down.
"I know he did."
"He was on break and Fury made him go anyway!"
Then he felt a contraction and shut his eyes tight.
Pepper rubbed his arm gently while it happened.
When it stopped he took deep breaths.
"Why don't we go for a walk? They're supposed to help speed things up." she said and he nodded.
Then he got up and they walked around the tower.
Every few minutes they stopped for a contraction and Pepper stayed with him.
For the next few hours he walked around, stopped to lay down and try and get some sleep and walk around again.
It had gotten worse and worse.
It was 1 in the afternoon and he was holding onto a door having a contraction right now.
When it stopped he took a deep breath and stood there quietly for a minute.
Then he looked at Pepper knowing he couldn't walk anymore.
"I have to lay down. I can't do it anymore." he said and she nodded.
"Let's go then." she said and helped him back to bed.
When they got there he laid down and fought the want to push.
Then Cho came in.
"How you feeling Sergeant Barnes?" Cho asked.
"I feel like I have to push." Bucky said and tried not to.
"Alright, let's see where you are." she said and checked.
"You're at 9. You can't push yet. Soon though." she said.
He started feeling another go off and put his legs a little closer together.
'I have to wait until Tony gets home to have him.' he thought and felt the baby get lower.
Three hours later he was fully dilated but fighting the want to push.
"Bucky, you have to push." Pepper said.
"I, I promised not to have him until Tony gets here." Bucky said fighting the pain.
"You have to." Cho said.
"No. I, I can wait."
"Please Bucky! You have to do it. I'm right here." Pepper said gently.
Bucky moved while fighting the baby from coming out.
"I can wait! I'm Sergeant James Buchanan Barnes and the Winter Soldier!" he said.
He felt the head go down deeper and had more trouble fighting it.
He took deeper and quicker breaths with his eyes shut tight and holding the sheets.
Then he grunted at the pain.
"You can't wait Sergeant Barnes. If you don't push you'll lose him." Cho said.
Bucky looked at her and knew she was right but didn't want to without Tony or Steve there.
Then he yelled in pain as the baby went down deeper.
"Alright! Alright!" he said and pushed hard.
"There you go." Cho said and he did it again.
He did it for half an hour and was exhausted.
"One more Sergeant Barnes." Cho said and he laid there panting.
"I can't do it." he said shaking his head. "I have nothing in me. Not even the strength I got after the serum."
"Yes you can Bucky." Pepper said and saw him. "You know what you can do. You protected Steve for years before he became Captain America and still do." she said and he looked at her. "You became an Avenger for a reason when you got control of yourself again. To protect the world. You can do this."
He nodded and pushed hard.
Then he heard someone crying and laid there panting with his eyes closed.
"There we go." Cho said smiling and went to get him checked on.
A few minutes later she came back smiling holding the baby.
"Here he is. Even though he's early nice and healthy." she said and Bucky held the baby.
"Hey." he said smiling.
"In coming call from boss." FRIDAY said.
"Answer it FRIDAY."
"Bucky! Are you OK?!" Tony asked worried and saw Bucky looking tired but smiling.
"I'm fine. I want you to meet your son." Bucky said and lifted him up a little. "He has so much hair." he said and chuckled.
"Hey buddy. I'm your papa." Tony said. "Hey guys, come meet someone."
"Who is it Tony?" Steve asked and froze at seeing Bucky holding the baby. "Oh my god."
"Meet uncle Steve, uncle Clint, uncle Sam, uncle Rhodey, uncle Thor, auntie Natasha and auntie Wanda." Bucky said smiling and gently waved the baby's little hand.
"What's his name?" Natasha asked.
"We decided to name him Peter James Stark when we found out it's a boy."
"He's so small." Thor said.
"He's got a lot of hair." Sam said.
"I know." Bucky said. "What I really wanna know is if he got anything I have after the serum."
"I don't know. But I don't care. As long as he's healthy I'm fine." Tony said smiling.
"I can't believe it's in such good shape for being early." Clint said.
"Maybe it's because of the serum?" Steve said.
"Maybe." Bucky said trying to stay awake.
"Why don't you get some sleep and we'll see you tomorrow?" Tony said gently.
Bucky nodded.
"Love you." Bucky said and looked at Steve. "Don't do anything stupid until you get home." he said smirking a little.
"How can I? You're taking all the stupid with you." Steve said smirking a little to.
Everyone looked at them confused.
"It's just something we do to each other. I call him a punk and he calls me a Jerk." Bucky said.
"Ohhh." they all said.
"Alright, see you soon."
"Bye." they all said and he hung up.
Then he looked at Peter and smiled.
"You'll meet papa tomorrow when they get home." he said and gave him a kiss.
Then he put him in his crib and fell asleep.
A few days later he was in the living room with the others and Tony was holding Peter.
"He's so small." Tony said.
"He's a baby, what do you expect?" Rhodey said smiling.
"True."
Bucky smiled and shook his head.
'This is one crazy family.' he thought.
