Sorry for the short chapter

Chapter 3

Dean wasn't able to sleep at all last the night before. He was so used to sleeping beside someone that he wasn't able to get comfortable even to get some rest. It didn't help that he kept thinking about what exactly was growing in his lover's womb.

If Sam didn't sleep with anyone else than there's a good chance that some kind of supernatural being most have done it. Dean's mind was all over the place with what that thing in Sam's body could be-a supernaturally demonic parasite that they never knew about, some kind of weird curse, or he even thought about how a shape shifter could have taken his form and slept with Sam without Sammy ever realizing.

He needed to find out what exactly was growing in Sam so they could take care of it before something bad happened to his Sammy. With that is in mind, he called the one person he thought could help before heading to the kitchen.

Sam was already there, eating some fruit and a bagel for breakfast. Kevin was at the stove making scrambled eggs. Dean walked over to the coffee machine and poured himself a hot cup before sitting down across from Sam. Sam didn't look at him but Kevin turned to him with a smile," You must be excited."

"About what?"

Kevin gave him a weird look," You're going to have a baby."

"No, I'm not," Dean replied coldly.

"Dean!" Sam snapped at him.

"Well…you're not the one who's pregnant but you're the father…I mean other father," Kevin said nervously.

Dean looked directly at Sam," You told him?!

"Of course I told him, it affects him to because we're all going to live together!" Sam snarled at him.

Kevin looked uneasily between the two," What's going on?"

They both ignored Kevin as they stared angrily at each other. Dean barked out," You forgot to tell him that I wasn't the father!"

"I didn't tell him because you are the father!" Sam screamed at him.

"That's not possible!" Dean yelled.

"It has to be because I'm having a baby!" Sam screamed back at the older man, trying hard to not to give into his urge to cry.

"It's probably not even human!" Dean finally growled at his brother, he didn't mean to bring the subject up to Sam like this but the heat of the moment got to him and it was out of his mouth before he realized what he was saying.

"What?!" Sam shrieked out as he finally gave into the urge and let the tears form in his eyes. Kevin watched both brothers with interest, his food left forgotten on the stove to burn. Dean calmed down a little when Sammy started to cry.

"You're sure you never slept without one else?" Dean asked softly, wanting to do nothing more than to hold Sam in his arms until he stopped crying.

"Yes!" Sam screamed at him.

"It's the only reasonable way you could have gotten pregnant," Dean reasoned with his little brother," It must have been some shape shifter or Crowley must have done something."

"Are you accusing me of sleeping with Crowley?!" Sam yelled in disbelief.

"No! No!," Dean said holding his hands up in defense," I just thought because he knows he's way spell he could have put some kind of weird curse on you."

"I don't believe you!" Sam yelled at him," It's a human baby, I know it is!"

Sam threw his bowl of fruit at Dean and stormed out of the kitchen. They watched him go and Kevin turned to Dean," Could it really have happened?"

Dean nodded," We hunt the strange world of supernatural creatures, anything could happen."

"What do we do if Sam isn't having a normal pregnancy?" Kevin asked finally turning off the stove and threw his burnt food away.

"First we need to find out what he really is letting grow in side of him," Dean asked.

"How do we find that out?" Kevin asked.

"I already called someone who can tell us if he's pregnant with a human, shape shifter, demon, or hopefully anything else."

"Who?"

Dean ignored the question and carefully stepped over the fruit on the floor before exiting the room," Clean up the mess, I'll be back later."

"Is it Castiel?" Kevin called out but got no response.
