So I read a Johnlock fic some time ago and I cannot, for the life of me, find it...
It's an A/B/O with John as an Alpha sub who gets discarded from military service to London, and Mike makes him meet Sherlock, an Omega dom; it's a bit heavy in smut, and it also recreates (if I remember well) the pool scene from TGG.
If a nice soul knows what I'm talking about, please tell! (I'm not that desperate in finding it but I randomly remembered it lol)
