All you need to know about this series is that the doc is titled "The Sex Buddy Fic". A series of 'made-them-do-its' which ended up telling a much bigger story.

The thing is, Derek’s really, really hot. Like, insane levels of attraction. What with the leather and the cheekbones and the stubble and the ass — oh god, that ass — Stiles can’t really be blamed, at all for freaking bragging. Now if only his college friends actually believed Derek existed.

If Derek’s life were a romantic comedy—which it’s really, really not, what with all the murder, mayhem, and supernatural elements—it would inevitably feature the moment when Erica brings Stiles home and he and sees, for the first time ever, not a gawky, uncoordinated teenager with a penchant for graphic tees and plaid, but a young man, taller than Derek now, with broad shoulders and large, capable hands that finally match the rest of him. Stiles would be walking down a staircase in slow-motion and Derek would feel the world tilt on its axis while his entire perspective on life underwent a paradigm shift. Stiles would be looking at something or someone else, and he’d laugh before his gaze shifted back to Derek and when their eyes met, it would feel like being struck by lightning. Like getting hit by the thunderbolt.

They find the baby under a butterfly bush, a sweet smelling buddleja with purple flowers and narrow, green leaves. The baby is dirty, wet and hungry, wrapped in a fur blanket, and this close its squalling is loud enough to wake the dead. -- Or the one where Stiles' mom was a harpy and passed certain genes along.

If he were being honest, it all started that first year, when Stiles called him Miguel and told Derek to put one of Stiles's shirts on. It sat in the back of his brain for two years after that, a quiet whisper he scarcely acknowledged. But they're fucking now, and it's brought it all back out.

Stiles goes to a Halloween party on campus to blow off some steam after a stressful week of midterms. He doesn't expect the party to be crashed by both a supernatural predator and Derek Hale.

Derek’s had a rough life up until this point. He’s beginning to learn perspective, and in the scheme of things, being a temporary woman is pretty minor.
