Stiles the Weird Demon
Peter shouts the last words of the exorcism ritual and looks up expectantly. The demon sitting on his kitchen counter just blinks and him, then yawns. Peter's tempted to just chuck the book he'd been reading from at him, but that wouldn't accomplish anything but earn him a ruined book.
Based on the prompt "I accidentally summoned some sort of demon and now it's just kind of hanging around my flat".
- Part 1 of Stiles the Weird Demon
Peter and Stiles start with Timothy and Amelia Argent, the power behind the east coast hunters. Peter tries to take it slow, he wants to savor this, but he smells the werewolf blood on their knives and can’t stop himself. He tears into Timothy, shredding his body to bloody ribbons while Stiles cleanly breaks Amelia’s neck.
“I thought the goal was to not make it look like a werewolf attack,” Stiles says with a smirk, watching Peter wipe off his bloody hands. Not that it helps; he’s covered in red to the elbows, with splatters decorating his front.
“That’s what I have you for, my dear,” Peter says.
Stiles and Peter go after the Argent family, tearing it down brick by brick.

"Talk to me," Stiles murmurs. "Can you control it? Is it too much?"
"I can control it," Peter says breathlessly. "It's...a lot. It's strength, and power, and...I can feel you."
Stiles looks startled at that, and Peter is too, honestly. Yes, they've spent months together almost exclusively with each other besides the company of the Argents they've hunted. But physical closeness and a sexual relationship don't mean pack. But here Peter is, with a white hot bond between him and the demon in front of him.
Peter and Stiles find an alpha.
