Here's a story where omegas are virtually worshipped, and it's hilarious to boot: Nature Is An Evil Bitch (http://archiveofourown.org/works/876091/chapters/1684101) by MaryRoyale. Enjoy!

Thank you this was exactly the type of story I wanted and it was very funny too :3

I think the Dawnbringer verse fits your first request and there are several stories in the verse: http://archiveofourown.org/series/26846

Thanks for the rec but I read that story.

Got another one. This has a/b/o, but omegas aren't exactly worshipped here. I would point it more toward the dark!Jensen side where he's a crime boss. Still an excellent story.

That was a perfect rec a/b/o +mob jensen+ well written = awesome Thanks so much ^^

For your last request, I would recommend "Red Like Blood In Veins of Blue" (http://rlbivob.livejournal.com/): it's dark!mobster!Jensen/Jared and it's really wonderfully written. It does have mpreg and it is a WIP, though, so be warned.

Thanks for the rec, I did read this before and it did perfectly fit number 3. But it's always good to reread stories.

For the first one, I'd check out fatebegins. She writes a LOT of a/b/o and only bottom!Jared, and usually the omegas are meant to be cherished.

My personal favorites are these two

This one is Jared being harassed when he goes into heat at school but Jensen takes care of him and it's very hot/sweet.

This one kind of fits one and three, with omega!Jared and mob boss!Jensen

This is a really wonderful verse where both Dean and Cas are in love with Sam and they end up in a poly relationship. Not really destiel though since it's mostly focused on Sam.

Thanks for the recs, although while the first four links were alpha and omega it wasn't what I was looking for. I did try to read them but I couldn't quite finish them.
the fifth link was a 2k oneshot and I couldn't...
The last rec I really enjoyed though.

I know it's been a while since you asked, but for the second category, The Bright Waters Meet by The_Bookkeeper (http://archiveofourown.org/works/842575) is a marvelous story.
