"Castiel?" Dean asked quietly. The name tasted differently in the harsh light of the lecture hall. He watched the other man's face change from terror white to scarlet in mere seconds. The blush from embarrassment wasn't so different from the red of exertion. Dean's lips quirked in a silent smile. This could be fun!

A breath of air forced its way through Cas' lips, followed quickly by a steadying inhale. "Hello Dean." That deep pitch was not just the result of sex roughened vocal chords, Dean noted. His cock twitched briefly.

"It's good to see you again, Cas." Dean's response was loud enough for the entire class to hear. He glanced up through the rows of students, their faces ranging from disappointment to confusion to envy. He smirked at them all. "He's an old friend," he explained jovially. Castiel glared at him through his eyelashes, but still refused to lift his head. Dean gave Cas' shoulder a squeeze before returning to the front of the room.

"You're friends?" He heard Gabriel hiss.

"Shut up," came the growled reply.

Dean giggled to himself. Oh yes, this was definitely going to be fun. "I'm just going to leave these papers on the front table. Grab one on your way out!" With that order in place, he launched into the first lesson.

The 75 minutes passed quickly for the professor, but he could tell Castiel was barely making it. Dean pulled out all of his old tricks. He dropped his pen at least eight times, rolled up his long sleeves above his elbows, tapped his lips every time a question was asked, and pointedly ignored the dark haired man in the first row.

There was a moment of frustration when Dean finally chanced a look and the blue eyes were everywhere but on him. It only took a second for the ire to evaporate because while Cas was carefully studying the exit sign above the doorway, he rubbed absently at the wrist Dean knew had been tied to the headboard. The grin that knowledge brought to his face really couldn't be attributed to Native American spearheads, but he pretended anyway.

"Heads up, there will be a quiz on chapters 1 and 5 next class, so since we only made it through half of 5 it is up to you to complete the reading! See you in two days!" Dean dismissed the class, but watched Castiel closely. His short friend was talking his ear off it looked like, and was hindering the intended flight from the room. Dean's amusement at Castiel's discomfort was bordering on sadistic now.

His attention was pulled from his bickering students by a loud, "Professor Winchester?" Dean whirled around at the familiar voice behind him.

"Jo!" he nearly hollered. A genuine smile broke across his features. The petite blonde grinned back before jumping into Dean's waiting arms. "What are you doing here?" he asked after he spun her around a few times.

"It's your first day of school! I haven't missed one yet," Joanna Beth replied smugly.

"Were you in the class?" Dean hadn't noticed her and immediately felt bad. Torturing a nearly perfect stranger shouldn't distract him so much.

"Yep. Right in the middle. You were too busy teasing a helpless dork to notice your bestest friend though, and now my feelings are hurt." Jo pouted, but Dean knew she was mocking him.

He rolled his eyes and scanned the classroom, but it was now empty. "I'll make it up to you tonight. My last class is out at 7:45 and I can meet you at the Roadhouse by 8:30. I will buy all your drinks while you regale me with stories about your hairbrained road trip. Sound good?"

"You are going to regret that offer, Winchester!" Jo cackled. Dean winced because he knew she was right. She may be little, but the girl could drink any trucker under the table and still walk a straight line. Jo grinned wickedly before giving Dean a kiss on the cheek and heading towards the door.

He grabbed his papers before following her out, slapping her ass before bolting towards his office. "I can still beat you down, asshole!" she yelled down the hall after him. Dean just flashed his dimples before ducking into his office.

After a second of thought, he locked the door.

His smart ass grin fell when he saw Castiel sitting in one of the chairs in front of his desk. "Hey, Cas…tiel," he added the last part at the warning look shot his way. He eased into the office chair the college had supplied for him. It sucked.

"Hello, Professor." Castiel replied coolly. "Who was that?" The ocean colored eyes flicked briefly to the closed door. Dean's followed, even though he knew what Cas was asking.

"She's just an old friend," he shrugged, not sure how to play this situation yet.

"Like me?" The tone was neutral, but Dean could have drowned in the words unspoken.

"Not quite," he answered carefully. "We've known each other literally our entire lives. Our dads were like brothers, so we grew up together. She and my brother are the only family I have left." Castiel's eyes narrowed, obviously trying to understand what the warning tone in Dean's voice meant.

By the headshake, Dean assumed Cas hadn't come up with anything, so he put on his professor hat. "What can I help you with this morning, Mr…?" Dean's gut twisted a little. They had to break the no-last-name rule, he supposed. But it still felt like violating some kind of code.

"Novak. Gabriel is my brother." The last was said through pursed lips.

Dean couldn't help the bark of laughter. "Well, Mr. Novak, I apologize for that." Castiel bobbed his head briefly in agreement. "I have no class for another hour and a half, so what can I do for you?" Dean folded his arms on the desk and leaned forward. The damn chair was already making his back hurt.

"The door is locked?" Castiel tilted his head, puzzlement furrowing his brow.

"I-yeah. Sorry. Hiding from Jo." Dean stood up and started cross the office. Castiel stood and blocked his path before he made it around his desk. "What…what are you doing?" Dean wasn't sure he could have been understood, because suddenly his lips were busy pressing against Castiel's.

The kiss burned its way down and his body began aching with need. Dean grabbed narrow hips and pulled them flush together. Castiel licked the seam of Dean's lips, and Dean welcomed the intrusion. Their tongues slid together wetly, licking and tasting. Dean held tight to Cas' hips and started rubbing their lower bodies together. The metal on metal sound of their belt buckles clashing together brought his upstairs brain up to speed with his downstairs brain, though, and he pulled the smaller man away. "What are you doing?" he repeated, panting.

"A repeat performance," came the dark rumble in reply.

The two men stared at each other for several seconds. Dean's mind flew through the million reasons this was a bad idea, and quickly decided none of them mattered more than getting to replicate their time at the motel. Maybe even come up with new stuff.

Dean eyed his office hungrily, already making plans. He brought his attention back to the person making his demented fantasies happen. "Ok," he huffed, and dove back into the kiss.
