A Wild Heart's Desire by mikkimouse
If there's one thing Stiles Stilinski knows, it's that Deputy Derek Hale absolutely Does Not Like him. The only reason Derek even tolerates him is because their kids are worryingly codependent.
So Stiles is understandably confused when a very feral Derek shows up in his backyard after a call gone wrong and proceeds to move in with him.
Cute story from "hate" to love! Plus it has parent Stiles and parent Derek in it! This is about my 3rd time reading this story and I really enjoy it. If you like Stiles and Derek being parents, plus weird situations getting them together then you will like this story.
