The Wrong Winchester

Summary:

Demons captured Castiel to get Dean pregnant but end up knocking up the wrong brother...

Notes:

I've been thinking about this for ages lol

Chapter 1: I'm what!

Chapter Text

Cas popped in with a worried look on his face which made Dean look confused for his boyfriend.

“Cas? What’s wrong?” Dean asked, stepping in front of Cas.

Cas sighed “There’s going to be a Nephilim born soon”

Dean looked confused “I’m sorry, a what?”

“A Nephilim, half angel, half human”

Dean still didn’t know what was going on, and he needed some answers now.

“And…?”

“It means we’re having a baby”

Dean spat out his beer that he was drinking “I’m sorry, we’re having a baby?!”

Sam walked in hearing the commotion “Who’s having a baby?”

“You are Sam”

Sam’s eyes widened “I’m what now?!”

Dean was even more confused than he had been in his entire life, first Cas tells him that they’re having a baby but then says Sam is pregnant.

Cas sighed, demons and their awful games.

“Why did you think I was gone for so long? I was captured by a bunch of immature demons and they didn’t know exactly what they were doing, but wanted to put a baby in you Dean, but used us to put the baby in Sam”

Sam looked down at his flat stomach looking concerned “So…I’m pregnant?”

“Yes, but it’s mine and Dean’s baby”

Dean paled; he was going to be a dad. One thing was he was just glad he didn’t have to carry it.  

Sam didn’t have any words, but he was mad. Why was it always him that got punished? He was going to have the baby and it wasn’t even his.

“So, I’m just like an incubator for a baby now?”

Dean looked cross “It’s not just anyone’s child Sam, it’s your nephew or niece!”

Sam rolled his eyes “And I’m the one that’s fucking pregnant!”

Dean sighed “Guess the hormones have started to kick in”

Sam shoved Dean in the side, he couldn’t believe this was his life, he’d sacrificed enough and now he had to spend nine months being pregnant when he didn’t want to be.

Cas felt bad, but there was no getting rid of this baby, Sam would have to go through nine months of pregnancy just for them.

“Dean, can you not put yourself in your brother’s shoes? Imagine if you were told you had no choice in being pregnant with a baby you didn’t plan?”

Dean sighed “I’m sorry Sammy”

Sam shrugged “I guess I’m just used to my life being a load of crap now”

Cas came up to Sam and placed a hand on his flat abdomen, he touched Dean’s head in the process and Dean was confused at first but then he saw it. He saw his baby; he heard its heartbeat. Of course, it was just the size of a little bean but that was his son or daughter growing in there. He was grateful for Sam.

Cas then touched Sam’s head like he had for Dean, Sam saw it, there was a picture of his womb and there it was, his niece or nephew growing, he heard the heartbeat and his mind changed. It wasn’t the baby’s fault they were put there.

Cas looked between the brothers “I wanted to do that to ease the tension, this baby is family to you both, I know we didn’t plan this, but I already know that you guys would do anything for a Winchester”

Sam and Dean looked at each other and smiled, and then Sam felt it coming. The bile rising down his throat, he ran towards the bathroom to throw up.

He groaned after his stomach was empty “You better be worth it kid”

Dean felt bad, his baby was already being a menace.
