Summary: Dean was pissed when Dad landed another new job in another new town that came with a tuition waiver for him and Sam. Just what Dean needed for his last five months of high school school, being surrounded by a bunch of spoiled rich kids he’d have basically nothing in common with. Don’t even get him started on the fact he had to wear a shitty school uniform.
When Dean walked into Chemistry on his first day, the last thing he expected was to find himself partnered up with basically the hottest guy he’d ever seen in real life; Castiel Novak. It was way too easy to like Castiel, and Dean was surprised by how quickly he got attached to him.
There was just one little kink he hadn’t seen coming: Castiel’s MIA lab-partner was his twin brother Jimmy. Doesn’t seem that bad? Did he mention the whole damn school knew they were together. Yeah, together, together. Which pretty much meant Dean was fucked, and not even remotely in the way he wanted.
Teaser:
“I’m serious, if you can’t pop the hood and fix it yourself without needing a degree in Computer Science then what the hell’s the point? The whole thing’s a conspiracy to make sure people keep buying new cars.” Dean said with a way too animated wave of his hand that nearly caught Castiel in the face.
“Huh, is it really that easy to fix older cars? I figured that since most newer ones just have to be hooked up to a computer to find out what’s wrong that it’d be easier. I mean, that’s what computers do.” Kevin said with a contemplative look.
“Oh yeah man, I mean one look under the hood of a classic and you’ll get it. It’s a different world. Sure you gotta know a little bit but nothing that a little reading and a lot of trial and error won’t get you. But the rest? It’s just… natural… intuitive… you just gotta get to know her and feel it out… listen to her respond.” Dean said with an almost glazed look.
“Dean are you talking about cars or sex?” Castiel’s gravelly voice asked next to him and Dean flushed bright red.
The table was quiet for a beat before every single person save Dean and Castiel burst out laughing. Charlie, the cute little redhead who was wearing a Harry Potter tie pin in defiance of the dress code, gave Dean a playful shove that broke him out of his embarrassment and had him chuckling along with them.
“But seriously man, come with me after school and I’ll let you take a peek under my Baby’s hood… promise she won’t mind.” Dean said with a wink that fed into the joke.
Kevin grimaced as he spoke, “Oh, I’d love to but I gotta catch the bus.”
Guess even when the buses were high end it still sucked to have to ride one.
“Poor little Kev won’t be able to get his license for another year and Mommy and Daddy won’t let him take the limo… say riding the bus builds character.” Balthazar said and slung arm around Kevin’s shoulder, pulled him into a headlock and ruffled his hair.
Dean didn’t miss the way Kevin’s cheeks flooded with color or the way he pulled away with a laugh that wasn’t entirely convincing.
“Hey man, I can give you a ride home if you want. If you don’t mind stopping to pick up my little brother.” Dean said as he shoved the last bite of his not entirely awful burger into his mouth.
A dainty hand slid down Dean’s shoulder to rest on his chest and he almost choked when an impressive set of tits pressed into the back of his neck.
“I’d love a ride Dean.” A feminine voice purred in his ear.
“You have your own car, Bela.” Castiel deadpanned from Dean’s side.
Only… was that a note of… possessiveness Dean detected under that careful neutrality? Also, when the hell had Bela vacated her seat. Dean must’ve been really caught up in the conversation.
“Maybe I wasn’t talking about a ride in his car, Castiel. Fresh meat looks like he’d be killer in the sack. Sounds like it too if he fucks as well as he takes care of his car.” Bela said as her hand dipped down lower, brushed just below Dean’s navel and caused an involuntary twitch in his pants.
The movement stopped abruptly and Dean looked down. Castiel’s fingers tightly gripped Bela’s wrist. Interestingly enough just the sight of Castiel’s handnear Dean’s crotch made his dick jerk even harder.
“Lunch is over, Bela. Time to go to class now.” Castiel said just as neutrally as before.
Bela yanked her hand away and straightened. Dean glanced around and saw the rest of the table were gathering their things and getting up.
“I’ll see you last period, Dean.” Castiel said before he headed off with Charlie and Jo.
Slightly puzzled, Dean dumped his tray and trailed behind Balthazar and Bela, who spoke to each other in hushed tones.
“…what the hell…”
“…Castiel… weird… playing at…”
“…Jimmy… pissed…”
