Supernatural Story Finders

Ok, I feel a little awkward doing this. but I'm not having any luck on my own... so here goes.

Sub/Bottom Castiel only.

1) Gagged Castiel. For any reason.
2) A fic where someone uses sextoys on Cas, fully consensual or dub-con fine.
3) A fic where someone punishes Castiel (ideally I'd love one where he breaks some kind of rule someone has put in place because they don't trust him, or because of the nature of their relationship D/s maybe, and he is punished for it, but whoever is punishing him doesn't reach the "forgiving" stage because they're too angry, are distracted by a hunt, or just assume Cas knows he's forgiven once the punishment is over, only to have to comfort him later when they realise he's been really hurting over it... I think people call it sub drop aftercare or something)
4) A fic where Castiel is an unwilling participant in a D/s relationship, would majorly love some public bondage.

and lastly, a slightly different (but still sorta the same)

5) Any fics where Castiel's wings are restrained. I'm talking actual tethering, maybe special demonic chains that don't let him uncurl his wings. Can be consensual (Maybe Cas does it to show his willingness to submit to them) or non/dub-con.
