LUST (Lust & Unresoved Sexual Tension) by theroguesgambit
"'Derek⌠Incubus, remember? This isnât⌠we arenâtâŚâ Derek cuts off his words with his mouth (itâs fucking effective, why hasnât be been doing this since the day theyâd met?) and breaks away again long enough to growl âIâll send it a fruit basket later.â -- The pack has to deal with an incubus. This was going to be a PWP but I'm a giant mushball so ended up being about feelings." Words: 8,278

Let It Burn Fast by RurouniHime
"'So.â Stiles rubs his thighs, snaps his fingers again restlessly and looks around. âThoughts? Comments? Revisions youâd like to submit for consideration?â Derek weighs it. âStiles, are you asking me to have sex with you for the good of the pack?â âIâyeah.â Stiles blinks a couple times, then smiles again. âYeah, I guess I am. That is the thing that I am doing.â (or, the one where Stiles proposes no-strings-attached sex for Magical Reasons and Derek somewhat unwisely agrees.)" Words: 32,562

Gonna Write A Classic by jezziejay
"The sexploits that Stiles writes about arenât autobiographical. Thereâs never been anything overtly salacious about his own sexlife, nothing that was ever going to be screenplayed for a porno, but he still has a very creative imagination to work with. Usually. Tragically, and frighteningly, his imagination has gone rogue on him. Itâs broken, flatlined, missing. âI have writerâs cock,â he whines at Scott over the phone. Or the AU where Stiles writes porn to help him through college and Derek becomes his muse." Words: 6,067

Will To Follow Through by owlpostagain
"'It depends entirely on how you look at it, I guess,â Stiles shrugs. âOn the one hand, instant healing and the apparently inherited ability to pull off leather at all times. On the other, serious attitude problems and a suspicious disappearance of eyebrows.â âEven Derekâs?â Danny snorts, âthatâs a lot of eyebrow to lose.â âI know,â Stiles agrees. âYou should see, itâs so weird. Every time I want to ask him where they go, except heâd totally eat my face off.â âThere are worse ways to die.â' Words: 42,411

"Derek. Stiles thought about him the most. Something told him that it wasnât the last time, far from it. He thought about his softness and his open desire to kill. Stilesâ hands remembered the heat of his hands. His neck longed to feel the coating warmth of Derekâs breath. His lips burned from the kiss that never happened. Everything was so fucking complicated. Except one thing. It was the only clear thought in his head. The one that made his stomach clench from fear, his heart stutter from hope, and his lips stretch in a smile. He was unconditionally and irrevocably in love with Derek." Words: 67,799

The Seven Lives Of Stiles Stilinski by glorious_spoon
"Stiles disturbs an abandoned temple and catches the attention of a goddess of time and fate. When he starts time-traveling involuntarily through the past, he's not sure if she means it as a curse or a lesson--but no matter when he travels to, he always seems to end up at Derek's side."

Saturday Night At The Movies by aussiebee
"After running into Stiles at the late night movies, Derek realises just how badly Stiles is handling the post-nogitsune fallout. He knows the feeling." Words: 7,349

We Should Be Lovers by stilinskisparkles
"Theyâre both more frantic this time, and Derek hopes itâs in part because Stiles has been thinking about him just as much as Derekâs been thinking of Stiles. He doesnât want it just to be because theyâre drunk, or because the partyâs mostly a bust. And, if it is, heâs determined to make it about him. He wants Stiles to remember him." Words: 6,643

And here, my honorable mention:
No One Chooses This Life by lapsus_calami
"Stiles wasn't running from his problems. Except he kind of was, but at least he was being productive while doing it. He gave himself one year. One year away from Beacon Hills, away from the pack, away from his dad. One year to get himself pulled together, to stop spiraling into panic attacks, to stop falling into pits of despair, to stop screaming himself awake every night. One year to learn everything he could about his spark, about hunting, about the supernatural. One year so that when he went back maybe, just maybe, he could do more good than harm." Words: 253,586
A sprinkling of Dean/Stiles in there, but it's not the focus. This fic is going 10 years strong, and they just posted a new chapter dec2024.
