*whispers* This is super cute and I hope you don’t mind that I’m taking it as a prompt?? Because I love it so and I wanna expand on the ‘verse (instead of working on stuff i should be working on aw yeah go me)
According to half the school, he and Sam are dating, and honestly, Castiel doesn’t blame them for the misunderstanding. Every day at lunch, on the bus to school, and in both Chem and Spanish, they’re inseparable. He’s openly gay, and Sam’s openly bi, and… he can’t say he’s never thought about it. But as much as he loves Sam, his feelings are platonic.
His feelings for Sam’s older brother are less so.
Dean Winchester is twenty years old, just over six feet tall, with green eyes and rough hands from shop work and killer taste in everything, at least, Castiel thinks so. Sam would beg to differ. Dean also loves teasing him and Sam, winking suggestively, and tussling Castiel’s hair and calling him “Cas”. Seventeen year old ‘Cas’ can’t talk right around him-and here he’d thought he was done with not being able to talk right a few years ago when voice cracks finally stopped.
The continual doodles of “Castiel Winchester” on the edges of his homework do nothing to stop the “Sam and Cas are dating” rumor. Perils of brothers, he thinks. He should know, as he has four of them.
Sam is completely aware, he’s sure- because Castiel isn’t exactly subtle in his admiration of the older boy. When Sam invites him to sleep over one weekend, Castiel narrows his eyes and asks, “Will Dean be there?” Sam rolls his eyes and confirms that yes, Dean will be around. “Good. I am a year past legal and haven’t gotten any sexual ‘action’ yet.”
Sam snorts. “And you’re not gonna, if you keep your heart set on Dean.”
Castiel shrugs. “The heart wants what it wants, Sam. But don’t be worried. I won’t be sneaking off with your brother this weekend.
Neither of them can sleep, maybe because sleeping bags on hard floors aren’t the most comfortable thing in the world. But it’s a noble childhood tradition, so here they are, sixteen and seventeen, sprawled on the floor with empty coke cans and half-empty chip bags scattered around them. Somehow it’s four in the morning and they’re playing ‘never have I ever’ and giggling like small children.
"Never have I ever… kissed Jessica Moore in the library," Castiel whispers.
"You dick,” Sam whispers back, lifting his middle finger before putting up a finger on his other hand to indicate another point for Castiel. “You can’t just list different places you know I kissed Jessica for pointage.”
Castiel rolls his eyes, not caring if Sam can see it or not in the light of the nightlight. “Fine, fine, you get one free one on me. Something you know I’ve done.”
Sam scrunches his nose. “I can’t think of anything,” he whispers, then stifles a laugh that springs up sheerly because they’re playing this stupid game at four a.m.
"Okay, how about…" Castiel glances up to the stairs, where the door to Dean’s room is hanging half-open. "How about ‘never have I ever wanted to kiss my best friend’s older brother.’ That’s an easy point for you."
"Come on, Sam. I could have made that one a lot raunchier. There are.. a lot of things I’d like to do to your brother. Accept it and we can move on.”
Sam drops back onto his pillow, facing the ceiling. “Yeah, but that’d be lying.”
Castiel watches him for a second, trying to figure out if Sam is bluffing or not. Because Cas has a lot of older brothers, and if this is a reference to the time Lucian had declared angrily that he might as well take Sam to prom, Castiel is going up-fucking-stairs because he doesn’t need any more of Sam’s jokes tonight. He’s trying to win a game of ‘never have I ever’ and he’s too sleepy to care about much else.
Castiel hunches forward, resting his elbows on his knees and his chin on his hands. “Would you care to explain that statement?”
Sam sighs visibly and rolls over to face his best friend, propping himself up with his elbows. “So, I think I’m in love with your brother.” Dead-panning? Referencing Lucian again? Or is he genuinely… interested in one of Castiel’s dumb older brothers?
"Which one?" Castiel whispers questioningly.
Sam doesn’t even answer, the moron, he just drops his head to his pillow and giggles like it’s the funniest question he’s ever heard, and Castiel, watching him, ends up stifling his own laughter as well, hand clapped over his mouth.
As they start recovering, Castiel whispers more insistantly, “No, seriously. Who are you talking about here?” Somehow his seriousness sets Sam off again, because he can’t even lift his head from his pillow this time. “Dammit, Sam, look at you.”
"I’s late," Sam gasps out as best as he can, the aftershocks of his laughing fit still in effect. "Cas. Cas, you like my brother, right?”
Castiel sighs- he just wants to know which brother he should make inappropriate comments about in front of Sam, which brother he should be purposefully seating Sam next to when Sam comes over for dinner, which brother to ‘accidentally’ have walk in when Sam’s half-naked. He honestly doesn’t know- Michael’s a real looker, Lucian has that long running gag about Sam and prom, and Raphael is freakishly intelligent, which he knows Sam loves.
"Yes, I like your older brother, Sam. I would just like to-"
“Which one?” Sam whispers, then bursts back into hysterical giggles.
Castiel grabs his pillow and physically whumps it onto Sam’s back, but it does nothing. Sam is too far gone. “I hate you, Sam,” he whispers, but the grin is obvious is his voice.
Sam finally pulls himself together and rolls over to look at Castiel again. “I mean it, though. I… have a really dumb, pointless crush on Gabriel.” Gabriel? As in the wildly inappropriate, snarky, messy, devious trainwreck of a brother? That was the one Sam was interested in?
"I thought you’d pick up on it and never let me live it down, honestly," Sam says softly. "Because it’s been forever, and… I really, really like him. I know you’re never gonna let me hear the end of it, but… if you could not tell anyone, I’d appreciate it."
Castiel nods, then flops down on his own sleeping bag, head nearly hitting the floor because there isn’t any pillow there any more. “I certainly learned something tonight.”
Sam smiles sheepishly. “I’m in love with your brother.”
"Same," Castiel sighs, and somehow that’s all it takes to send them both back over the edge into fitful, belly-aching laughter.
The fact that Sam now doodles “Sam Novak” on the edges of his sketchpad does nothing to help stop the “Sam and Cas are dating” rumor.
Maybe more people in this school could stand to ask which one.
