Fire, Fury, and Flame (Sterek)

Stiles Stilinski was never going to be the omega who got knocked up right after high school, and then he's accidentally artificially inseminated with a stranger's sperm.
Awesome.
And the father of Stiles's baby just so happens to be Derek Hale. Half-feral, quite possibly a murderer, and pursued by a gleefully sadistic band of hunters who are only too eager to use Stiles and his baby to hit Derek right where it hurts.
Joy.

Notes:
I've never seen Jane the Virgin (though I hear it's great), but I'm like 99.9% sure it doesn't involve werewolves, hunters, kidnappings, insane road trips, and baby names inspired by Disney movies. So I'm just borrowing the most basic plot: young person gets accidentally inseminated with a stranger's sperm and decides to keep the resulting baby.
Basically I woke up at three a.m., had this idea, went back to sleep, and wrote it in the morning as soon as I woke up again.
In my little headcanon, everyone in this world is A/B/O, but only some are full-shift werewolves.
