#if someone doesn’t write a fucking sterek drabble to this i will legit go out of my freaking mind
"Fuck it," Stiles said, advancing on Derek. He pushed him back into the stall, ignoring Derek’s huff of surprise as flicked the lock and rounded on him.
"Stiles, wha-" Derek tried to protest even as his hands tangled in Stiles’ shirt, dragging it up as the teen dropped to his knees.
"I want to suck your cock and you want me to suck your cock, so I’m gonna do it and you’re gonna try to be quiet," Stiles spat out through gritted teeth while he yanked on Derek’s belt and jeans, opening them roughly. It amazed Derek that someone could sound so angrily enthusiastic.
Not that he minded. He’d always thought Stiles was hotter when he was pissed.
Not that he thought about it, because Stiles was 17 and Scott’s best friend and -
"Fuuuck," Derek let out when Stiles tugged his briefs down just under his balls. Fuck, this was really happening and there wasn’t a single fiber in him that wanted to stop it.
"Shhhhh," Stiles warned, licking wetly along the underside of Derek’s quickly-hardening dick.
The club music reverberated in the walls as Derek bit down on his lip, trying to hold back the totally indignified whine that bubbled up in his throat. Stiles pressed one hand up against Derek’s abs for leverage and braced the other against the wall, drawing Derek into his mouth slowly with a low moan of his own.
Derek’s brain exploded with sensation, the heat and softness of Stiles’ mouth overwhelming him for a minute. He just tried to hold on as Stiles began to move, tongue swirling and his stupidly-erotic fucking lips wrapping around Derek’s cock like they were made for it.
"Stiles- fuck, Stiles, I’m not… gonna la- shit-" Derek gripped the back of Stiles’ head, tangling in his hair and squeezing in encouragement. He felt Stiles grin around him before taking him deeper, swallowing him.
Derek was losing it fast, heat descending sooner than he thought possible. Stiles just kept going and ignored Derek’s cut-off warnings, punctuating his movements with little moans of his own that fried Derek’s brain.
“Stiles-“ Derek came, digging his fingers into Stiles’ shoulder and knocking his own head back against the wall. Stiles just took it all, holding Derek in his mouth with his eyes closed in ecstasy.
When he was done, Stiles slipped off and stood, pulling his briefs back up and redoing his jeans and belt while pressing his tongue into Derek’s mouth slowly, lazily.
Dazed, Derek let his hands fall to Stiles’ hips, grunting into Stiles’ mouth when he pulled the belt too tight.
Breaking the kiss, Stiles met Derek’s eye with a smirk. “C’mon, we’ve still gotta find the succubus.”
"Yeah- wait," Derek started, grabbing Stiles’ arms as he turned to go. "What about… ?" He pointedly eyed the bulge in Stiles’ jeans.
Stiles’ eyes grew wide. “Yeah, my brain isn’t even remotely capable of handling that right now.” And with that, he walked out, leaving Derek there alone, trying to convince himself that he felt more guilty about what just happened than he actually did.
