LF Au Dean raises Teen!Sam

[azzyj]

       Okay, I'm not really sure if this exists, but I'd love to read a story where Cas brought Sam back in Season six with his soul, but he wasn't able to get Sam's body right, and Sam ended up still in the body of a teenager.  Then Dean ends up raising Ben and Sam together, or any other variation like that.  
       Anything where Dean ends up raising Sam would be great though.
