Okay this is my very first Supernatural fic. I've just recently become a fan of the show and instantly fell in love with Castiel and Dean. This idea just wouldn't leave me alone even though I have other unfinished stories. I couldn't help it; they are just so hot together. Please review and tell me how I've done. This is unbeta'd so all mistakes are mine.

Sam Winchester was in love. Not just in love, but head over heels you're -the-reason-I-wake-up-in-the-morning love. The object of his affection was none other than professor, one Dr. C. Novack. No one knew what the C. stood for, which just added to the mystery that was Professor Novack.

Sam hurriedly made his way to class, knowing that if he didn't arrive early that all of the seats closets to Dr. Novack would be taken. He paid scant attention to the stately halls of the Humanities Building of the prestigious Belford University. He cared nothing for the marble pillars and floors, nor for the antique oak bookcases. All that Sam cared for was reaching Theology 304 before any of Dr. Novack's fan club did. Finally reaching the lecture hall, Sam was grateful to discover that only two other people had beaten him there.

The first recognized as one of his best friends Brently Masters. The 6'2 red head was one of the first people outside of his brother Dean to befriend Sam. The other person was a willowy blonde whom Sam can't recall seeing before.

"Hey Sam, I saved your seat" said Brent in greeting. The seat he was referring to was directly in front of Dr. Novack's lectern. Throwing his friend a smile, Sam slid his massive. Frame into his seat. Brent introduced the blonde as Chelsea Gifford, a transfer from Rockford University. She kept throwing flirty smiles Sam's way, but he couldn't have cared less. More students started to trickle in. Any many now the object of many lust filled fantasies would walk through the door.

"So I hear that Dr. Novack is a real ball breaker" said Chelsea, obviously trying to break the ice with Sam. Brent sent her a sympathetic look, while Sam's snapped back in her direction so fast his shaggy brown hair fell over his eyes. "He only seems like a hard ass to those not willing to put in the work" he practically snapped at the poor girl. Her pale blue eyes widened and she wisely turned her attention to her text book. Brent gave him a knowing smirk.

Sam's obsessive fangirling over the professor was nothing new to Brent. While Brent was straight as an arrow, even he found Dr. Novack attractive.

"Chill out Winchester. She doesn't know any better. Anyhow have you had any luck in your search?" he asked Sam, turning the conversation to Sam's favorite pastime. For the past three years Sam had been finding new and inventive ways to search for Dr. Novack's first name.

Sam gave a massive sigh. "No...and I was sure that payroll would have him listed as something other than C. Novack."

"Dude, I can't believe that you hacked the schools mainframe just to learn his first name. You didn't check your grades or anything…you are so sad!" exclaimed Brent.

"It just kills me that I've been his class for three years and I still don't know his first name!" griped Sam, not to mention that he wanted something a little more personal to mentally scream when he jerked off.

"Well I've been giving it some thought, and I was wondering why don't you apply for his T.A. position? I know you're not a grad student or anything, but with his rep I bet nobody wants the job" suggested Brent. Sam's eyes lit up at his friends words. Why hadn't he thought of that?

By then the rest of the class had made it in. Sam's gut clenched in anticipation of Dr. Novack's entrance. Sam knew that he always entered the class a 8:00 sharp, no matter what. Finally Dr. Novack entered like he always did, quietly not acknowledging anyone's existence. Sam's eyes drank in the dark beauty of the professor.

Windswept chocolate locks that looked as if they'd never seen styling product, long sooty lashes that framed shocking blue eyes, full pouty pink lips, and just the merest hint of stubble, all set in a face that would make the heavens weep…at least Sam thought so.

Dr. Novack made his way to the lectern, the class instantly fell silent. Sam felt his breath hitch as he watched long graceful fingers remove a pair of designer frames from an inner pocket. The square black frames magnified already intense eyes, making them completely captivating. Then for Sam the real magic began, Dr. Novack began his lecture. His voice, that gravel smooth honey voice sent shivers down Sam's spine. By the end of the class, Sam was painfully hard. It was his usual state upon leaving this particular class. He'd gotten very good at disguising his body's betrayal.

"So are you going to ask him now?" asked Brent as he gathered his belongings. Sam saw how Dr. Novack was surrounded by scantily clad coeds each vying for his attention. The barely checked annoyance on Dr. Novack's face made Sam think that later would be a better time to ask. "I think I'll wait" answered Sam as he grabbed his newsboy satchel to cover his impressive erection.

The rest of Sam's day passed in a flurry of lectures and notes. Sam loved school, he really did. He found his major on in Pre-Law (with a minor in Religious Studies) to be challenging and rewarding. He was however very glad this day was almost over. He was waiting for his brother to pick him up. Normally Sam drove himself, but today his car was in the shop. That meant waiting for Dean.

Sam didn't mind the wait. Dean worked for an engineering firm all the way across town; which he wouldn't if it weren't for Sam. Sam had been pushing Dean to do things his entire life. When it was time for Dean to go to college Sam pushed for Belford, because if Dean went first he would be there to take care of Sam. When Dean graduated with his Bachelor of Science degree in Mechanical Engineering, Sam pushed him to get his Master's, because Sam was not ready to be on his own. When Dean got his Master's degree and wanted to move back to Kansas to be closer to their parents, Sam talked him into staying and getting a job at an engineering firm, and buying a huge loft downtown. Which of course he let his baby brother live in rent free.

Dean always put Sam's needs above his own, but that was just Dean's way. The familiar rumble of Dean's pride and joy broke Sam from his thoughts.

"Come on Sammy I haven't got all day to play taxi" said Dean in greeting. Sam rolled his expressive brown eyes as he opened the door. Before he could get into the Impala, a flash of color caught his eye. Dr. Novack's blue scarf trailed brightly behind him as it was caught in the wind. Sam blushed as he realized that Dr. Novack was going to pass right in front of him. Now would be the perfect time to ask about the position.

"Uh Dean I need like five minuets" he said tossing his bag into the car. Dean gave a huff, but cut the engine anyway. Sam steeled himself before calling out to the professor. The dark haired man stopped at the sound of his name. Up close Sam found those jewel toned eyes paralyzing, he couldn't hold his gaze for long.

"Uh…I'm…uh" stammered Sam.

"You're Winchester, Samuel. What can I do for you?" asked the doctor impatience coloring his tone. He shoved his hands into the pocket of his black peacoat. Sam took a deep breath, still unable to meet the other man's eyes.

"I…I was uh...wondering about the T.A. position…uh that is have you filled it?" Sam asked in a rush.

Dr. Novack regarded him in silence. Sam felt seat start to trickle down his back. Before the silence became unbearable, Dr. Novack spoke. "Are you asking me or the sidewalk Mr. Winchester?" he snapped. Sam's eyes flew to the professor's face.

Sam was dimly aware of Dean getting out of the car, and casually leaned against it. "Is the T.A. position still available Dr. Novack?" Sam managed to ask. Again the professor gave an assessing glance.

"It is…come by my office Monday if you are truly interested" he finally answered. Sam knew he was grinning like a madman, knew that a blush stained his face. This was it, this was his chance. Sam lost himself in thoughts of working lunches, staying late to grade papers together; maybe even dare he think it learning the doctor's first name. Images of spending long hours behind closed doors with his crush whirled through his head.

He was abruptly pulled from his thoughts by his brother's voice. "So Dr. Novack, you have a first name?" asked Dean, his trademark smirk in place. Sam's eyes widened in dread, he'd born witness to many verbal smackdowns given to people who inquired about the doctor's first name. He watched as those sinfully blue eyes were turned on his brother. Sam had little pity for Dean. All his life he watched as Dean used his charming good looks to his advantage.

With his jade green eyes, sandy blonde hair, muscular frame, and overall rugged good looks, Dean Winchester was rarely denied anything. "Of course I have a first name…do you?" demanded Dr. Novack. Sam noticed that Dean didn't seem to have trouble meeting Dr. Novack's gaze. Sam mentally sighed. Dean never did heed signs of trouble. It would be up to him to keep his brother from embarrassing himself and therefore Sam right along with him.

"My name's Dean. Dean Winchester. And what about you doc, got a name?" replied Dean flashing another boyish grin.

As Sam watched, it seems as if Dr. Novack was appraising his brother. The dark haired professor took a step closer to Dean. They engaged in a staring contest, neither looking away. Sam started to feel really uncomfortable. Finally the professor gave a subtle smirk and held out his hand.

"Castiel. Castiel Novack" he answered. Sam's brain sputtered. He barely noticed Dean take the professor's hand, holding it a little longer than necessary. Sam couldn't believe that Dean had gotten Dr. Novack to give his name. After all he'd gone though to get the doctor's name all Dean had to do is ask! Sam tried not to freak…on the one hand Dean got the hot doc to spill his name, but on the other now Sam knew his real name. And what a name it is. Castiel, a fitting name for an angel. Maybe he'd thank Dean later.

If Sam had been a little more aware, he would have recognized the look in Dean's eyes and pulled him as far away from Dr. Novack as possible. Dean Winchester was on the prowl. "So Cas, you busy Saturday night?" asked Dean, still standing far to close to the professor.

Sam sputtered, surely his brother did not just ask out HIS Dr. Novack! "No, I am not" answered Castiel, not noticing Sam's indignant sputtering. "Would you like to be?" smirked Dean, looking down at the dark haired man. Sam's heart hammered in his chest, he knew that look. The wide eyes (to show off the beautiful jade coloring), the boyish grin (showcasing perfect white teeth), and the tiny head tilt (so that the sun hits him just so showcasing the smattering of freckles on his nose)…Dean was looking to get lucky!

Sam couldn't believe his ears, surely Dr. Nov-…Castiel wouldn't accept such a crude invitation…right? Sam could only watch as Castiel reached into an inner pocket and pulled out a card. Quickly he scribbled something on the back.

"Here is my number and address. You may pick me up at seven sharp, not seven o five or seven ten, but seven. We will go to that new Thai place on 3rd , is that acceptable?" said Castiel.

Dean took the card with a smile. "No problem at all Cas…I'll see you Saturday" answered Dean. "At seven sharp Dean Winchester, I abhor a lack of punctuality above all things" said Castiel as he turned to continue his walk. As he did, he looked at Sam as though surprised to see him still standing there. "Good day Samuel" he said briskly walking away.

Sam couldn't move or speak. He was frozen. It was as though he witnessed a mac truck run over a bus full of nun and orphans, and the whole fiery mess was hurled into a homeless shelter…for the blind. The horror left him mute.

"Yo Sammy let's go!" yelled Dean, already back in the Impala. In shock Sam got in the car. This had to be a nightmare thought Sam.

"Man, Castiel is hot! Hell if I'd known they had professors like that in religious Studies, I would have changed majors" crowed Dean. Sam shot him a venomous look. Dean was taken aback.

"What's got your panties in a twist Samantha?" demanded Dean. To Sam Dean was just as clueless as always. Sam forced the words past the lump in his throat. "That's…that's….he's my…mine…" he stammered.

Green eyes widened in understanding. "Oh…Sam…Sammy…say no more I get it" said Dean. Sam turned to Dean, the tightness in his chest unclenching. Dean was his big brother, the one who always looked out for him. If Sam wanted Castiel for himself he was sure Dean would step aside, that's just the kind of brother he was. Now Dean would break his date with Dr. Novack, and maybe he would put in a good word for Sam.

"Dude I get it, don't worry about it. I'm sure Cas will let you be his T.A. even if our dates sucks balls, which it totally won't. You know I'm going to pull out all the stops for this one. I mean sure the staring is a little weird, but the view more than makes up for it" smiled Dean. Sam couldn't speak. The look on Dean's face told him that he wouldn't break his date. That meant it was up to Sam to put a stop to things. Silently he began to plot.

Okay that's it. I might leave this a one shot…or I could be persuaded to continue…what do you think?
