Benny is a pureblood werewolf on the run from his pack to keep his 12 year old potential hybrid daughter safe after the torture and death of her mother, Andrea.
When Dean went to Stanford, Sam turned him down and Dean hunted on his own until the Wendigo tore him up. Now, all Dean has is a bad leg and some scars to show for it. He's just on the run from his life in general.
Two broken men end up in the same spot, but how will Dean react to becoming friends (and maybe more) with a monster? A story of pain, growth, family, and finding true love.

Past, present, future and everything in between

When a spell gets cast accidentally, 2005 Dean finds himself in 2015, in the bunker. With a vampire who's apparently his boyfriend and a world that's way bigger than he could have ever imagined.

I read one recently that was Mpreg but based in cannon post purgatory where Dean is pregnant with cas's baby and runs away to be with Benny on his boat but can't find it!

If you like abo this one is long and really well written

John is a bounty hunter and has dragged the boys around behind him. Omega Dean has pretty much raised Alpha Sam. John isn't abusive per se, but rather traditional (omegas are the homemakers, caregivers, weak). Sam and John have always butted heads, so Sam happily runs away to college, not really thinking about Dean. Now that his alpha son is raised John thinks it's too dangerous and too much worry to have Dean around, and thinks the best thing he can do is mate off Dean to one of his work pals. He doesn't intend to give Dean a choice, and Dean rather objects to this. He steals the Impala, some cash and hits the road.
