AN: Here's my first full sastiel/sassy story! I'm excited!

Warnings: mpreg, possible mild language, slash, and rape of a minor in later chapters. (I know, spoilers, but I have to put them in here)

Disclaimer: If I owned it, you would be watching this instead of reading it.

I didn't really place this in any particular season, because I don't want to deal with some of the issues these boys have. Besides, this doesn't completely fit in with the series, and all things considered, part of this is technically set in the future of the show. I have made this pretty AU, so I made two lists for you guys:

Living characters: Bobby, Charlie, Keven, Jo, Ellen, Ash, Rufus, Balthazar, Gabriel, Pamela, Gordon Walker, Alastair, Meg, Garth, Jody, Chuck, Sam, Dean, Cas, and the Samulet (yes, I just list it as a character)

Dead characters: Lucifer, Michael, Raphael, Naomi, Zachariah, Anna, Uriel, Azazel, Ruby, John and Mary, Samuel Campbell, Adam, and Jess

I know there are a lot I didn't mention. If I didn't mention them, either they don't matter to the plot of this, or I didn't care enough to gloat over their death. Although, I did throw in some names in the 'living' list just to throw you off. This story is basically me putting to paper my perfect made-up version of my favorite show. Also, the apocalypse happened, but Sam has his soul now as well as his hell-memories. No Mark of Cain. No Metatron (as in, not ever), no purgatory, no trials… Sam and Dean are both fully human, and Cas has never been without his grace.

Title because this story is a lot about family and because of this quote from 3X16 (No Rest for the Wicked):

Dean: "This isn't your fight!"

Bobby: "To hell it isn't! Family don't end with blood, boy!"


Rainy nights were always long for Sam because he found it extremely difficult to fall asleep with droplets of water tapping incessantly against the windowpanes. Tonight was no different as he lay in Cas's arms in the room they were sharing. Ever since they had started sleeping together in the non-literal sense of the word, they always got a motel room separate from Dean, whether they planned on doing anything or not. Cas still didn't sleep, but he didn't leave every night like he used to. He would lay beside Sam and rest as he kept Sam safe. Even though Sam was bigger than Cas's vessel, Sam was the one who was wrapped in his boyfriend's arms most of the time.

"Sam," Cas said, "why have you not fallen asleep yet?"

"The rain's keeping me awake," Sam replied.

"Ah yes, you do have difficulties with that, don't you? Is there anything I can do?" Cas was always more than ready to offer assistance with any of Sam's needs.

"Not really. We can talk, though. I don't think sleep is going to come to me unless you knock me out, which I'd rather you didn't."

Cas smiled, although Sam couldn't see it. He always enjoyed talking with Sam. "Is there anything in particular you would like to talk about?" he asked.

"Well, there is one thing I've been meaning to bring up in the last few weeks." Cas didn't say anything, waiting for Sam to say what he wanted to discuss. "We've been… dating for over a year. I know I'm happy, and as far as I can tell, you are, too. Dean hasn't complained about it either. I was just wondering if you'd want to get married?"

"Sam, you couldn't have timed this more perfectly. I had just begun to consider asking you the same question. I love you so much, more than I thought I would ever be capable of, and I want to spend the rest of our lives together. I cannot think of anything I would like more than marrying you."

"So, do you want to do the mating ritual before or after we get married?"

"You would do that with me?" Cas asked. He was honored. It was perfectly natural for angels to do it with one another, but Cas would have understood if Sam hadn't wanted to do the ritual. Sam was a human and it was a foreign concept to him. Marriage might not have been something Cas had anticipated in his future, but as far as Cas could tell, there was no real physical, emotional, or mental change in someone during a marriage ceremony. In other words, Cas was doing nothing much out of the ordinary if he were to marry Sam, but for Sam to be mated to Castiel was a foreign concept.

"Well, yeah. Like you said, it will strengthen the bond we share. I know I'm looking forward to that feeling," Sam stated with a soft smile.

"So, does this mean we are… engaged?" Cas asked, having had to search for the right term.

"Yeah, it does," Sam said, feeling happier than he had thirty minutes before. Sam reveled in the moment until he realized something. "Oh great. I just thought of something," he said to Cas.

"Is there a problem?" Cas asked, somewhat concerned.

"Maybe," Sam said. "You see, it's sort of a human custom of sorts. The only way I know to explain this is to make up an example. Let's say there's a guy who wants to marry a girl. Before he proposes to the girl, he would ask her father's permission. If the father was unavailable he would go to the girl's mother, or uncle, or brother. The point is, I think it would be wise if we checked this out with Dean. I'm sure he won't have a problem with it, but he'll want to be asked first, and probably by you."

"Yes…" Cas said.

"What is it? You seem like you're thinking about something," Sam said.

"I am just not sure how much your brother trusts me when it comes to you."

"What do you mean?" Sam asked.

"Well, it's just, after we decided to become boyfriends, Dean gave me a very… serious threat regarding what would happen if I ever 'screwed with your heart'," Cas said, using air quotes, which Sam had noticed the angel seemed fond of now that he'd learned what they were.

"Of course he did," Sam muttered. Leave it do Dean… "Alright, well in that case, definitely ask him. I'm ninety percent sure he won't have a problem with this, but ask him about it, and pretend we didn't have this conversation. Don't let Dean think you asked me without asking him first. He might get a little mad, or something."

"Alright. I'll ask him the next chance I get," Cas said.

"Good. Let's talk about the mating ritual. I mean, how does that work exactly?"

"Well," Cas said, "part of it requires at least one person to speak in Enochian. I can do that part. I already have already memorized what must be said. While I am speaking in Enochian, we will be facing one another with a bowl between us. In that bowl will be dust from the lowest cave beneath Mt. Everest, three feathers from my wings, which must be pulled out by you—"

"Will that hurt you?" Sam interrupted.

"Only as much as if you were to pull out a few hairs from your head all at once. The pain will be small and brief. Also in the bowl will be three strands of your hair, pulled out by me. We'll need the blood of another human and another angel – to signify that someone from your species and from mine approves of what is being done. I believe Dean and Gabriel would be good candidates for this. When I have finished speaking the Enochian, we each drop a match into the bowl and once the contents have all been burned, the mating will be complete."

"That was a little simpler than I was expecting, but that's good," said Sam. "I'm tried and it's stopped raining, so I'm going to sleep now."


AN: There's chapter one! Thanks for reading. Reviews are my favorite. I need to know how I'm doing! And I've said in the past that I won't post anything until the entire work is completed, but it's taking me a while to write this one, so I decided to post a chapter even though I'm not even halfway done with this story yet. It may be a while before I post chapter two because I don't want to get ahead of myself. So, yeah, I guess that's all. Tell me what you think!
