"Yeah just like that."
Derek stops abruptly and cranes his head to listen. He was just going for a run past the Sheriff's house, (an innocent run okay, he was not actively hoping to run into Stiles, or hear Stiles, or even smell Stiles for fuck's sake) fine maybe he was secretly hoping to get a tiny peek of the boy. A miniscule peek really, not even a peek, more like a fleeting glimpse.
Alright fine so sue him. Derek wants to see Stiles.
He can't be blamed though, the boy is dangerous. With his golden eyes, flailing limbs that never seem to stay still for any amount of time and his devilish mouth that would constantly spout sarcastic remarks to anyone within a one foot radius. Not to mention his boundless loyalty and complete inability to give up in the face of death. The kid was one of a kind and Derek grew increasingly more fascinated with him every single day. So when Derek hears the focus of his musings making what sounds very much like sex noises Derek listens.
"You like that baby?"
Derek's teeth come fully out of his mouth, tips sharp and deadly.
"Nice and wet huh?"
Derek growls deep and guttural.
"So smooth."
Derek's eyes glow red.
"You're all mine."
Derek runs as fast as he can towards the voice. He'll kill whoever Stiles is with! He'll rip out their goddamn throat and then shove it up their ass! Stiles belongs to Derek, no one else can have him.
Derek turns the corner and dashes into the garage where he comes face to face with Stiles…
and Stiles' Jeep.
Stiles has a rag in one hand and a hose in the other. His left leg is lying on the hood of the car where he was trying to get a better angle and his mouth is hanging open in shock. Because Derek just surged into the boy's garage where he was washing his Jeep, not having sex. Damn.
To top it all off Stiles is soaking wet, there's soap suds sticking to his hair and his shirt is positively drenched.
The universe is out to kill him.
"Uh hey Derek," Stiles says. "Come to get your car washed? Cause I don't know what you heard but this is not an actual bona fide establishment and ompfffffff-"
Derek crushes Stiles to his chest and kisses him with all the intensity that has been stirring in his veins since the first time the brat talked back to him. Stiles goes slack at first then he takes the leg that's not on the car and wraps it around Derek's waist pulling him in even tighter. Stiles hand smooth's the stubble on Derek's face so gently and lovingly that Derek feels his breath hitch.
"So you want to help me finish up here where we can both get soapy and wet and then get even more wet by watching off in the shower together?" Stiles asks, while wagging his eyebrows theatrically.
Derek answers by pulling him in for another kiss.
They make it a weekly routine to wash the Jeep together.

Later On:
Stiles: I can't believe you thought I was having sex! In my garage! With the door open! Where anyone could hear! Where my dad could hear!
Derek: What was I supposed to think? You sounded like some actor in a low budget porno.
Stiles: Wait, you watch pornos?
Derek: What no! I just mean you were really obscene.
Stiles: You totally do. You watch pornos and then take care of Derek Jr.
Derek: -glares at Stiles-
Derek: Derek Jr.?
Stiles: Would you prefer Little Were? Were Stick? Senior Werenis?
Derek: I don't know why I like you.
Stiles: Cause I'm your big hunka human lovin.
Derek: -Rolls eyes- Go buy more soap.
Stiles: Fine
Derek: And sponges.
Stiles: okay.
Derek: And lube.
Stiles: Lu...oh hell yes.
Author's Note: Yes, "hose" was an innuendo.
