[oh internet hivemind] OT3 fics?

I should be using Pinboard for this, I know, and maybe later this afternoon I will fire it up and take a look. But in the meantime I'm interested for people's recs, in any fandom, for OT3 fics. M/M/F, the crunchier the better (i.e. not just PWP, much as it pains me to specify that), though I admit I probably won't have time to read very long ones all the way through. But lay 'em on me, if you've got em.
