Both werewolves?

[dayoneexposure]

I've just finished reading Of A Kind and was wondering if there were any other fics like that. Either both of them being werewolves and/or there being a significant age difference... but still being of age (nothing illegal, but one of them feels it's wrong).

I'm also looking for fics about werewolves mate for life. I read one where Sirius joked around about it, but it not actually being true.
