The first time he heard it, he wasn't quite sure he heard it right.

"Um, what was that Cas?" Dean looked at his former angel on the floor who was surrounded by pieces of a puzzle he had been working on for the better part of an hour.

Cas let out an exasperated sigh before he repeated himself, "I said, 'We should obtain a child'."

Yep. Even though Dean couldn't believe his ears, he had heard him right. What would've given Cas this idea? They had been officially together for about a month now and it took everything Dean had to not freak out about Cas' new suggestion. A few weeks ago Cas had suggested they get a dog, claiming that their little house was "one species short." Dean was partially on board with that idea, but the next week Cas seemed to have forgotten all about it and was cooking up his next plan. That was the week that he suggested they get a cat, and for the same reason. It was still fresh in Dean's memory how utterly disappointed Cas looked when Dean told him he was allergic to cats. When he saw that those big blue eyes were close to tears, Dean suggested that they still get the cat and forget the allergies. He could take allergy pills and heck, he would even wear a gas mask if it got to that. He would have done anything to wipe that sad look off of his angel's face.

Just like the dog idea, the next week the cat conspiracy was totally forgotten. However, the idea of having a little munchkin of some sort running around the house on all fours was not forgotten, according to Cas' new proposition.

Dean, completely dumbfounded, shook himself out of his trance and looked at his hands, suddenly finding them quite interesting.

"Well, uh, Cas, I, um," he stumbled, "I think we should- I mean, we're not even married yet for cryin' out loud!" Immediately after saying this and realizing he said 'yet', Dean's cheeks flushed a bright crimson as he twiddled his thumbs. All the while Cas watched him with complete fascination.

A small smile tugged on the corner of Cas' lips as he said, "We can fix that."

Dean started choking on air. Out of concern, Cas patted his back until he calmed down. When he was stable again, he looked to Cas with wide eyes and said, in disbelief, "Really?"

"Really," Cas said as he grabbed Dean's hand.

"When?"

Cas squeezed his hand to emphasize his point, "Right now."

This left Dean speechless. Sure he had thought about marriage with Cas dozens of times (per day) but he was always sure that he would have been the one to make the move.

Dean's speechlessness made Cas extremely uncomfortable. Was that too much to ask of him? Did he not want to marry him? His nervousness made him start to talk simply to fill the open space. "Of course, it doesn't have to be now. We can always wait a year or two if that makes you comfortable. Or if you don't want to get married at all, that's-"

Dean was kissing him before he could finish his sentence. Cas noted that his lips tasted of cinnamon and apples, and this made him crave applesauce.

After a long while, when they realized that oxygen was a necessity, Cas slowly pulled away.

"So... is that a yes?"

Dean shook his head and smiled, which gave conflicting messages to Castiel.

"Yes it's a yes my silly angel." Dean leaned forward, grabbed Cas' stupid tie that he insisted on wearing indoors and pulled him in for another kiss.
