Found: Fics with twins: Sam and Jared, Dean and Jensen

[wonderfoo.livejournal.com]

Hi - I'm looking for fics where Sam and Jared are twins, and Dean and Jensen are twins - could all four be from same family or not. Or, all four are brothers, not necessarily twin pairing. If Misha and Cas are brothers too, the more the better.

I know I read one specifically where Misha or Cas was crushing on Dean (I think). Other details are spotty at best - I remember someone was on a date and there was mistaken identity because of all the twinnage.

Any hoo - any directions to fics like this would be great. Probably AU by definition.

Edit: Some good recs in the comments. Thanks everyone.
