Based on this College AU Professor!Dean/ Student!Cas
Dean is one of those really easy-going professors. He insists his students call him Dean and always shows up to class a little bit hungover (even if it’s an afternoon class). He’s loud and brash and calls students on their bullshit when he sees it, but at the same time he’s willing to mentor those whom he sees potential in. Obviously, he’s incredibly popular and his classes are very tough to get into. All his students admire him… except for one.
Castiel needs Professor Winchester’s (he refuses to call him Dean) seminar as part of a graduation requirement. He’s been putting it off for three years now, but his advisor Mr. Singer tells him he can’t avoid it and he’s “shit outta luck.” Castiel reluctantly registers for Professors Winchester’s upper level Ancient Mythology seminar. It’s clear from the moment he walks into the nearly-empty lecture hall, he’s going to hate this.
Prof. Winchester has no syllabus, preferring to have the class lead wherever the semester takes them. He calls on students without having them volunteer to answer, leaving Castiel stammering more than once. After the first exam, Castiel receives his essay back with a big, fat “C” across the top. When he approaches him later to contest the grade, Prof. Winchester just shrugs lamely.
“It’s wrong, Cas,” is the only explanation he offers.
“Wrong?” Castiel mutters. “It’s… an interpretation… You asked for our interpretation! How is there a right or wrong!”
“Well, it’s a wrong interpretation,” Prof. Winchester states coolly.
From then on, it seems like Prof. Winchester is out to get Castiel. Every seminar dissolves into a heated argument, almost exclusively between the two of them. Every paper gets returned bearing more red marks than black ink with pithy little comments like “Try Harder, Cas” or “Seriously, which textbook are you reading?”
It’s enough to make Castiel scream, and usually does.
Worst of all is the way that Castiel can’t seem to control his growing attraction to the Prof. Winchester. It’s amazing how sexy he is when he’s arguing. Dean’s… uh, Prof. Winchester’s eyes get so bright and passion. His voice gets deeper too, turning into a low snarl. When they are in the heat of an argument, Castiel finds himself hypnotized by the way Dean’s jaw clenches and he wonders what it would be like to run his tongue along it. More than once, Castiel has come over his fist with Dean’s name on his lips… not that he’d ever admit that.
Castiel is caught off-guard when, after a particularly bitter debate, Prof. Winchester asks if Castiel could stay and speak to him after class. He’s worried he may have gone too far, calling Prof. Winchester an “arrogant jackass”, but once the rest of the class leaves, he doesn’t look upset.
“I wanted to talk to you about your plans for grad school,” Prof. Winchester says.
“I’m sorry, what?” Castiel asks.
“There is a fellowship opportunity available,” He says, collecting his belongings and slipping them into his bag. “I’d like to throw your name in for recommendation, that is if you are up to it.” Castiel stares at him in stunned silence. He did not expect this at all.
“You want to recommend me… for a fellowship?” He finally mumbles out after a minute.
“Unless you have other plans,” Prof. Winchester says, “but I really think it would be a shame if you didn’t. You are one of the smartest kids I’ve ever taught.”
“But… But in class…?” Castiel trails off, completely confused.
“Look, I might not agree with all of your ideas, “ Dean replies. “but your support of your them is sound and pretty clever. I’d love to see you expand on your interpretation of the Code of Hammurabi.” Castiel huffs a surprised laugh.
“A fellowship?” He asks, “Seriously?” A fellowship would mean Castiel could actually afford grad school, something he’d thought was impossible before. It would mean more time to devote himself to what he loved, maybe even getting published.
“Well, I can only offer a recommendation,” Dean offers a small shrug, “But it does carry some weight with the board.”
Castiel can’t contain himself. He launches himself at Dean in a grateful hug, wrapping his arms around his neck. Without thinking he pulls back, planting an enthusiastic kiss directly on Dean’s lips. It takes him a second for the realization of what he’s just done to dawn on him and a second more to realize that Dean is, in fact, kissing back. It’s brief and frantic and Castiel can taste the remnants of mint and tobacco on Dean’s tongue.
The soft click of the lecture room door brings him back to reality. Castiel pushes back from Dean harshly, his expression bewildered. What the hell has he just done?
“Hey Dean,” his TA Charlie ducks her head into the room, “Did you still want to go to lunch?”
“I’ll be right there, Charlie,” Dean answers, slightly breathless. He looks back at Castiel, licking at his lips. The door closes with another click.
“I got to go,” Castiel blurts out. Pushing past Dean, he gathers his stuff and rushes up the stairs. He can hear Dean calling his name as he exits the lecture hall.
