Twins

John's smile dropped in shock, and Dean and Cas slowly turned to look at the doctor with wide eyes.

"What?" John asked.

"It's twins. Two boys."

John's smiled slowly made its way back, and he asked if he could see them. The doctor nodded and motioned for John to go in. Dean looked at Cas in shock, and a smile made it's way onto his face.

"Cas. I have two younger brothers. I can't believe it. This is real." He got up and started pacing a bit.

After a few minutes, Cas stood up in front of Dean to stop him and placed his hands on his shoulders.

"Babe, calm down. Take a minute." He said, placing his hand on Dean's cheek.

Dean smiled softly and nodded, sitting back down next to Cas.

A few minutes later, the doctor came back out.

"You two can go in now." He smiled.

Dean quickly stood up and made his way to the room, Cas following after him. Dean walked over to the bed and sat in a chair next to it. Cas stayed closer to the door, not wanting to disturb this time together.

"Hey. How are feeling?" Dean asked, rubbing Mary's hand.

"I'm fine. There is some people I'd like you to meet." She smiled before looking at John, who's back had been turned.

John turned around and Dean saw two beautiful baby boys in each of his arms. One was asleep, while they other was awake, moving his tiny fingers around. Dean smiled and teared up slightly when he saw them.

John handed them to Mary, so that Dean could see them better.

"Mom, they're beautiful. What are their names?" He asked, letting the one who was awake grab his finger. His hands were so tiny compared to Dean's.

"Samuel," Mary paused, looking at the sleeping baby, before looking at the other and speaking again. "And Adam." Mary smiled.

Dean let a tear fall as he stared at them.

"Hey little guys. I'm your big brother. And I'm gonna be here for you guys every step of the way, no matter what." Dean leaned down and gave each of his brothers a soft kiss on the head.

Cas smiled at his husband, letting his own tear fall before wiping it. Later that night, Dean and Cas stayed at the castle with John and Mary, helping out with whatever was needed, and making sure Mary was well rested and comfortable. Dean, John and Cas all tool turns checking on the twins in the middle of the night while Mary slept.

6 months passed and they had learned some differences between Sam and Adam. A really big one was that Sam slept more and Adam cried more. Another one was that Sam was more of a mama's boy than Adam was, and Adam was a daddy's boy.

(I just realized that's sort of how it is in the show.)

Dean and Cas visited two or three times a week, mostly to spend time with the babies and help Mary with things. One Thursday morning, they decided to visit again. When they got there, John was holding Adam and feeding him a bottle, and Mary was holding a sleeping Sam.

"How are things today?" Dean asked as he and Cas sat down.

"Good." Mary smiled. "Sam's been sleeping for a little while now." She looked down at the baby in her arms. Dean smiled at them.

"Do you wanna hold him?" Mary asked.

"Sure." Dean said, holding his arms out so Mary could place Sam in them.

"Heya Sammy." Dean said quietly, smiling down at him.

Cas smiled at his husband, and watched his eyes light up with joy at the sight of Sam. He could tell Dean really loved this brothers, and would do anything he could to protect them. Sam woke up a few minutes after being in Dean's arms, looking up at his older brother. After a couple minutes of just staring, Sam smiled before spitting up all over Dean and himself.

"Crap." Dean said, handing Sam back to Mary so he could clean himself. Mary chuckled a bit and cleaned up Sam.

"I think he likes you." Cas chuckled, wrapping his arm around his husband.

Dean laughed at that and the looked at his father.

"He finished eating?"

John, who was no longer feeding Adam and was just holding him in his arms, looked at Dean and nodded. He smiled down at his son, laughing a bit when Adam smiled at him.

The four adults talked for a little while longer, until there was a sudden foul smell and John felt his arm heat up slightly. His eyes widened and he slowly looked down to see his arm covered in slightly runny poop, and Adam giggling innocently.

Mary tried her best not to laugh, but let a couple snickers out before handing Sam to Cas so she could help her husband. Dean grabbed some rags and helped John clean his arm while Mary took Adam in the other room to give him a bath and change him.

"First time that's happened." John chuckled, wiping his arm with a rag.

"I have a feeling it won't be the last." Dean chuckled as well and Cas laughed.

Mary returned around 15 minutes later, holding a now clean Adam.

Dean asked if he could hold him for a bit before he and Cas had to go home, and Mary smiled before handing Adam to Dean. He smiled wide as he looked down at him, rocking him slightly. Adam smiled back and giggled a bit. Cas stared at Dean while he held Adam, and smiled. He thought about how much of a good dad Dean would be.

A while later, Dean and Cas said goodbye, and left to go home.
