Word length: 2300
Prompt: Cas is a young, arrogant professor (subject up to the author, but something like theology or literature would be delicious) - Dean's the student. Sex in the office, however the author wants, but don't make it about grades. Maybe Dean is really smart and it's a huge turn on for Cas. Bonus points for academic dirty talk.
A/N: All religious texts referred to in this story can be found in Documents for the Study of the Gospels, David R. Cartlidge & David L. Dungan, Editors.
"And how are you finding your course with Professor Adler?"
"Okay, I guess." Dean shrugged his shoulders. "Honestly, dude's a bit of a prick."
Cas leaned back in his office chair. "This time last semester, I'm sure you thought I was a bit of a prick."
Dean barked a laugh. "Opinion still hasn't changed." Cas raised a cool eyebrow, and Dean grinned. "A prick who's an awesome professor."
"How kind of you," Cas said flatly. He rose abruptly to his feet. "I shouldn't keep you from your studies."
"Hey, man, I didn't mean anything by it," Dean protested. "I mean with the prick stuff, not the awesome part. That I meant."
Cas stared at him intently for a long moment, and Dean felt a trickle of sweat run down his back and his mouth go a little dry.
"My apologies," Cas said stiffly. "I am perhaps sensitive about being compared to Zachariah Adler."
"You're nothing like him," Dean answered immediately. "We're talking about the Maccabees right now, and he's managed to make it boring. Dude, it's pitiful, people dozing off during bloody revolt."
Cas favored him with one of his almost-smiles, and Dean felt heat coil low in his belly. He tried not to be obvious as he watched the stretch and pull of Cas's dress pants and vest as the professor sat back at his desk and faced him.
"Well. I do have a quite fascinating piece on the Maccabees here that I could loan you," Cas said, swiveling to look at his overflowing bookshelves.
"Yeah, awesome, Professor. I actually, uh, I had a question for you." Dean stopped and cleared his throat, marshalling his thoughts as Cas looked at him questioningly. "I heard Anna Milton decided to take some time off, and I know she was going to TA for your Gospels class, and I was wondering," he just needed to spit it out, Cas's face was going all closed-off, and maybe this had been a horrible mistake, but he'd thought, last semester - he'd never connected to another teacher like this before, and not just because he ached for Professor Castiel Novak to fuck him so hard Cas lost complete control and needed Dean to put him back together again, "Um. If you need a new TA…"
"Dean." Cas sighed and took off his glasses, clunky grandfather glasses that had come back in and out of style a few years ago but which Dean knew had belonged to Cas's actual grandfather. "You are a wonderful student…," Only in Cas's class, and this speech had rejection written all over it, "But it would be unethical for me to have you as my TA."
Dean blinked at him. "Unethical? Jesus, Cas, if you thought I'd suck, just say so, don't make up some ethics crap!" He surged to his feet and reached for his bag, but Cas's hand closed tight around his wrist.
"Stop. You know why it would be an ethics violation."
Dean's face flamed. Cas knew, about the crush, the daydreams, maybe even about the picture of him on Dean's phone that Dean jerked off to repeatedly.
"Fuck, I'm - I'm sorry, I didn't mean -" Dean babbled until Cas shut him up with his next words.
"On my part especially."
"Wait. What?"
Cas looked at him steadily. "It would be unethical for me to supervise a TA I harbored desire and affection for."
Dean went completely still. "You, uh, and me…"
Cas raised his eyebrow. "There's no need to be coy, Dean. I know how you feel."
Dean bristled slightly. He'd never been coy in his life. "Little arrogant of you, don't you think?"
Cas took a step forward and Dean shifted back until he was stopped by the heavy oak desk. "It's not arrogance. It's right."
Their mouths were so close, those pink chapped lips Dean had been longing to bite and lick since September. Cas smirked at him. He was an arrogant bastard, but he was also right. Dean leaned forward and crushed their lips together. It was rough and inelegant, and then Cas placed his hands on Dean's hips and pushed him onto the desk.
"Damn," Dean breathed, tangling his fingers into Cas's hair and pulling his mouth down, trying desperately not to break the kiss, his tongue fighting Cas's for dominance. And then Cas pulled away.
"Cas…" Dean whined, and blushed as the nickname escaped his lips. Cas arched his brow.
"How long have you been calling me that?"
"Since, uh, the Coptic Gospel of Thomas," Dean mumbled.
"Really?" Cas leaned in again, hands on either side of Dean, and licked at Dean's neck, pushing with the weight of his chest until Dean gave in and fell back against the desk, knocking over a jar of pens and sending several notebooks and papers to the floor. "When I said," Cas ran his tongue across Dean's jugular, "'when you make the two one,'" he nibbled slightly, "'you shall be Sons of Man.'"
"That is so out of context," Dean said, biting back a gasp that turned into a guttural groan when Cas snaked his hand between them to work at the button on Dean's jeans.
"Are you going to teach me now, Dean?" Cas's voice was thick with amusement and desire both, and he pressed one more kiss, quick and light, to Dean's lips, before dropping back down into his desk chair. "Tell me what you learned." He glanced up at Dean's face through his long, dark lashes before focusing his attention back on Dean's jeans. "Go on."
"Fuck, now?" Dean asked, pushing himself up on his elbows to watch Cas shove his pants and underwear down. He was already hard and leaking and he noticed, with no small thrill, that Cas's mouth was watering. But Cas had stronger willpower.
"Acts of Holy Apostle Thomas, Dean. What do you remember?"
Dean raked his brain. It was just so hard to concentrate when sex was right there - oh! "He convinced all those women they didn't want to have sex anymore!"
"A little simplistic," Cas said, but leaned forward in his chair and gripped Dean's thighs firmly as he closed his mouth around the leaking cock. "More," he mumbled.
Dean couldn't tell if he meant more cock or more gospel, so he gave him both, hips straining against Cas's grip as he fucked slowly into his mouth as he tried to remember. "Uh, it was about asceticism, right? The opposite of what we're doing now?"
Cas grinned around his cock and swallowed. Dean fell back against the desk, his head banging the hard oak as he moaned. That was it, his brain was offline. Cas was pulling off, pressing little slurping kisses against his shaft, and if he swallowed again, Dean was going to come down his professor's throat. Cas didn't, though, but when he got to the head, his tongue darted into the slit, making Dean cry out. He did it again, and again, and Dean's heels were drumming against the desk by the time Cas sucked him down. All the way down, his hands coming up to slide beneath Dean's t-shirt and stroke the soft skin there. And then Dean really did come his professor's throat.
Cas kept sucking at him until it was almost painful, lapping him clean and humming appreciatively before pulling off. Dean stared at him through half-closed eyes while he reached into a desk drawer and pulled out a bottle of water, while his throat swallowed the liquid down.
Cas gave him an amused smile. "I have to admit, Dean, I have wanted to do that since the moment you walked into Study of the Gospels."
Dean barked a laugh. "Glad I could help."
"And was there anything I could do for you?" Cas asked, and now who was sounding coy? Dean leaned back up on his elbows.
"I, uh, always wanted you to fuck me on your desk. Hard."
Cas's eyes widened in surprise and his breath came a bit faster. "I see." He fumbled open another drawer and pulled out a bottle of hand cream, and then his face fell. It was almost comical. "Dean, I don't-"
"I'm clean," he cut him off. "Had this embarrassing crush on my professor, a lot of dates with my right hand."
Cas crawled onto the desk to kneel over him and kiss him, his tongue fucking deeply into his mouth. "Thank you," he managed between kisses. "I'm clean, too, and I'm going to fuck you so hard. That's a promise, Dean."
Dean shivered as Cas pulled away, unbuckling his belt and stepping out of his clothes by the time Dean had managed to shrug off his t-shirt.
Dean's breath caught in his throat. He'd imagined, many times, what Cas would look like naked. He'd expected his body to be, not soft, exactly, but not lean, wiry muscles, not a smattering of scars that made him look rougher, more powerful in a different way than when he stood at the front of his classroom and fixed Dean with his intense blue stare. He hadn't expected the living equivalent of the Greek and Roman statues that adorned his religious history texts - broken and crumpled stone here made whole and vibrant flesh. Flesh that was eager to touch his own, as Cas used his body as a mattress, chest against chest and lips coming up to suck his bottom lip between them even as one slippery finger circled his hole before pressing firmly inside.
Dean couldn't help bucking up at the intrusion, and Cas nipped at his jaw, making a soothing noise before sliding down his chest to suck a nipple between his teeth. Dean whimpered, his hands coming up to hold onto Cas's head. Cas's finger rubbed inside him, soon joined by a second, and his teeth worked on Dean's other nipple. Dean was breathing heavily. He could feel Cas's hard cock against his thigh, and it felt huge. Maybe he should've had a different fantasy.
And then Cas's fingers found his prostate.
"Cas! Unh!" Which was not what he'd been planning to moan. He'd been thinking he'd say something worthy of Dr. Sexy, but Cas was - "God! Do that again, fuck, please, please."
Cas chuckled darkly and added a third finger. His tongue dipped into Dean's navel and his cock was smearing pre-cum all over Dean's thigh and Dean could not stop babbling.
And then Cas pulled his fingers out. Dean wanted to protest the loss, but he didn't have time, because Cas's slick cock was sliding into him, a slow dragging burn until Dean didn't think he could possibly hold anymore. Cas pushed in another half inch and stopped, fully encased.
They stared at each other a moment, both wild-eyed and slack-jawed, before Cas started to move. Slow at first, then faster. He fucked like he did everything else, firm and deliberate and intense. Dean couldn't look away from his eyes, pupils blown so wide only a thin ring of blue remained. And then Cas began to hit his prostate and Dean's eyes rolled up as he almost passed out from the pleasure. He was fully erect again, Cas's chest rubbing against his cock and driving him further towards the edge.
Cas gripped the edge of the desk above Dean's head and slammed into him hard enough to make his teeth rattle. He was panting, and Dean was making a rather undignified grunting noise, but Cas didn't seem to mind. Each thrust was more powerful than the one before, and then the angle changed.
Dean's eyes popped open as Cas pulled entirely out, Cas's feet hitting the tile floor, and then he was being dragged across the desk. Cas gripped his shoulders and thrust inside him.
"Dean," he commanded, "Tell me how much you want this."
"Unffff," Dean moaned. "Fuck, Cas, fuck me harder."
"Tell me," Cas said again.
"Okay! Fuck," Dean panted. "I want your cock to split me open and fuck my brains out. I want you to pull me out of Adler's awful class and fuck me in the janitor's closet 'cause you can't wait to get all the way back here to shove your cock in me."
The desk creaked loudly and shifted in its grooves as Cas growled, low and guttural, and slammed into Dean's prostate one more time before spilling into him, coming in thick spurts. His face was sheened with sweat, mouth open and lips glistening and cheeks flushed. Dean had never seen anything more beautiful in his life. He ached to come, too, but Cas was pulling away, sliding out of him and falling back into his chair, breathing heavily.
"Cas," Dean whispered. "Please."
Cas looked at him, sweaty and debauched, and rolled the chair the few inches he needed to suck Dean down again, lips sealed around Dean's cock. Dean came again with a grown as Cas swallowed around him, lapping him up before nosing up through his pubic hair to mouth at his stomach while Dean caught his breath and stared.
Cas left a smear of his own come on the desk when he pulled Dean into his lap and kissed him, thrusting his tongue inside until Dean was filled with the taste of both himself and Cas. His dug his fingers into Cas's hair and pulled him even tighter, their sweaty bodies sticking together as their tongues caressed each other.
Dean finally pulled back and rested his forehead against Cas's. Cas ran his fingers up and down Dean's back and nuzzled Dean's neck.
Dean huffed a laugh.
"Okay, you definitely convinced me I shouldn't be your TA."
Cas smiled, a full-blown one this time, and pressed a kiss to Dean's jaw.
"Of course I did. I'll convince you again later tonight in my bed."
