For real we need more fics where Stiles crushes on Deputy Parrish and Derek is jealous.
"Wait, wait, wait," Stiles said, hauling Derek back. "Let me do it this time."
"Do what?" Derek asked.
"The seduction routine. I can absolutely flirt with that hot deputy.”
"And he can absolutely roll his eyes and tell you to beat it, because you’re his boss’s son.”
"Uh." Stiles paused. "Forbidden fruit is the sweetest? Also, he’s into Star Wars. We could always bond about Star Wars.”
Derek sighed and pushed gently at Stiles. “Forget it. I’m doing this.”
But Stiles didn’t budge. “Nope. C’mon, man. It ain’t gonna hurt if I, y’know, try to charm him. I’ve been told I’m very charming. Maybe he’ll fall for my flailing instead of my non-existent suave flirting, but he’ll still fall.”
"And I’ll rip his throat out," Derek muttered, under his breath, as Stiles turned to blink at him.
"Nothing," said Derek, letting his grin turn toothy and menacing. "But if you fail - and you will fail - then we’ll have to break into the police station the old-fashioned way, and if we get caught doing that, it’s be your fault.”
"My fault. Gotcha." Stiles cleared his throat, straightened his shirt and ambled confidently into the station.
Derek watched with narrowed eyes as Stiles leaned against the front counter, quirked a smile at Deputy Parrish, and got another smile in return. A far too friendly smile.
"Fuck it," Derek said, and marched in after him.
"Wh-what are you doing here?" Stiles said, when Derek materialized at his shoulder and dug his fingers into Stiles’s shoulder.
"I just remembered we have something to do."
"Yeah," Stiles hissed, low enough for only Derek to hear. "And I’m trying to do that something, so maybe you could scram?"
"Oh, hello," Deputy Parrish said. "You’re Derek Hale, the ex-con, right?" His voice was a little too polite. “May I ask what you’re doing with the sheriff’s son?”
"None of your business," Derek spat, pulling Stiles closer against him as Stiles spluttered.
"Allow me to remind you that Stiles is still underage."
"Yeah? You didn’t seem to recall that, a couple seconds ago.”
"On the contrary, I have a photographic memory." Parrish’s tone was downright icy. "I don’t forget anything. Especially faces. I never forget faces. Particularly those that’ve been on Wanted posters.”
"Why the hell are you guys talking about me being of age?" Stiles squawked, and then followed that up with, "Hey!" when Derek literally dragged him out of the station without so much as a word of goodbye to Parrish, who followed their departure with a suspicious gaze.
"What the heck were you doing?" Stiles said accusingly, the moment they were out, shoving Derek off him. "I thought you were the one who didn’t want to break in the old-fashioned way!”
"Change of plans," Derek said, without bothering to explain himself any further.
"Change of plans, he says," Stiles mumbled to himself, running a frustrated hand over his hair. "I get it. You don’t think I’m sexy enough to seduce anyone, or cute enough to, I dunno, distract them, or whatever, but - ”
"Shut. Up," Derek said, and yanked Stiles in to kiss him.
Several minutes later, Stiles was plastered against the hood of Derek’s car, with his legs trembling and his scent thickening with musk and sweat and his mouth a soft, bruised red.
"Oh," Stiles said, eventually. "Oh.”
"Yes, ‘oh’." Derek drew away and walked across to the driver’s side. "Now get in the goddamn car. We have a breaking-and-entering to plan."
