Kurt needs comfort in d/s relationship

[nikkiglitz01.livejournal.com]

I've just read Late by nightrose and now I'm looking for any other fics where Kurt is in a dom/sub relationship, with Kurt being the sub. 

I want fics where Kurt has to use his safeword or something happens that makes him upset or insecure and his master(dom) has to comfort him while Kurt keeps trying to apologize.
