Dear friends hi! I am relatively new to spn fandom and still (mostly) trying to navigate myself in this HUGE fandom. First time posting a request here and i want to thank anyone, who will even read this, in advance. 
I read a very nice short story a couple of days ago and i didn't save the link (idiot!). The story goes as follows:

Sam and Dean enter a bar to hustle some pool but the waitress informs them without delay that no poker games or pool hustling is possible in that bar and instead points at their mechanical bull who can win to whomever stays the most on it, five hundred dollars-the establishment's offer. Sam tries but manages only a couple of seconds on the bull, while Dean lasts a lot longer and wins the money. Afterwards Dean tells the surprised waitress that he has had plenty of practise from riding Sam! 
Detail: The waitress - in her mind - refers to Sam as "Shaggy" and to Dean as "Pretty".

I'm looking around for some alpha/omega sabriel fics, preferably omega!Gabe with alpha!Sam, also I'd really like for Gabe to still be an angel.

Also looking for some Sam/Cas or Sam/Dean/Cas mating fics. I've been looking everywhere and I can't find any even remotely close to mating (as in the boys become Cas' mate). Nesting and mpreg to go with would be super appreciated but isn't a must. Thank you!

There is actually a very specific fic I am looking for and I remember most of all that it had absolutely no quotation marks in front or at the end of the dialogue. There was another version provided that included them for reader convenience but the author originally wrote it without ANY "..." marks.

The story has Sam going to a gas station by himself and then never coming back and Dean's struggle over the years with dealing with this. It was a very long fic and I believe part of a big bang or some other event, but I would very much like to find it again. The key things I remember was at one point Sam's jacket is found by some people by a lake and I don't believe any angels or demons made an appearance and that it takes place sometime around s1 or s2 as I don't recall Dean having died or gone to hell, but I could be wrong.

The lack of quotations is the key trait of this fic that made it stand out to me.

Are there any fics out that has Dean running away from Sam and John either because they hardly notice Dean when they're butting heads or because he just can't take it anymore when they fight. When they notice that Dean is gone - it could take them awhile to take notice if you want- they get worried and I want them coming to Dean and not the other way around plus I want Dean to be doing well without them. If Dean doesn't come back I want the fic to focus on John and/or Sam and they feel guilty and Dean's absence being really obvious to them. It can be slash or gen, doesn't matter

On a completely different matter can you find me some Destiel fics with a very submissive!Dean/possessive!Cas. Dean can be one of those petite and delicate kind of guys or just needs to feel loved and Cas feeling suddenly very protective of him the minute he sees him.

Any potential triggering content is under the cut!
