Bad-Father!John Fics

[acqiel.livejournal.com]

I'm on a bit of a bad-father!John kick at the moment (mostly because I love the angsty h/c it causes for the boys), hence my two requests:

1. Are there any fics out there where John mistreats or abuses Sam (physical, mental, etc.), yet when Sam tells Dean about it Dean doesn't believe him (at least initially)?

2. Conversely, are there any fics where John is hard on Dean or treats him unfairly and Sam protects him/stands up for him? This can be physically or verbally protecting Dean from John's actions, or just backing Dean up when John pushes too hard. Not looking for age-regression fics. I've seen this theme come up in deaged!Dean fics, but never in scenarios where their ages are kept unchanged.

Really appreciate any recs you send my way! Any pairing and timeline are accepted.
