Castiel moaned quietly into the kiss, his lips parting to invite Dean inside. Dean slipped his tongue across Castiel's bottom lip before sliding his tongue inside the angel's mouth.

"Hmm..." Dean moaned softly, enjoying the taste of Castiel. He tasted of black coffee and honey, two flavors Dean never expected would go together.

Castiel's hand found the front of Dean's pants and rubbed the outline of his erection through the rough fabric. Dean groaned at the sensation, rolling his hips into the angel's hand.

"Cas..." Dean said breathlessly as he pulled back slightly, his green eyes gazing into clear blue ones.

"What're we doing?" Dean questioned, not entirely sure what he wanted Castiel to answer.

"I don't know, Dean, do you wish to stop?" Castiel responded uncertainly, his eyes searching Dean's.

Dean's mind was racing, high off endorphins as his heart felt like it was going to beat out of his chest.

He pressed his forehead against Castiel's, eyes closed as he contemplated his thoughts.

"I think we should slow down a bit," Dean finally spoke after a minute or two of silence, bringing his hand up to cup Castiel's face.

"I can do slow," Castiel nodded, his own hands coming to rest on Dean's hips as he gently pulled Dean closer towards him.

Dean returned his mouth on Castiel's, kissing him softly, with less urgency and hunger. The two sinking into one another as their lips fit perfectly against each other.

Castiel placed his hands on Dean's lower back as Dean's settled around Castiel's neck, their kiss deepening.

"Fuck it, Cas... I can't do slow, nothing about me is slow," Dean huffed pulling away from Castiel.

Dean moved his hand to the front of Castiel's slacks and began rubbing him, not surprised to find the angel sporting an impressive erection.

His other hand returned to the back of Castiel's head, fingers tangling in dark hair as he went in for another kiss, this one full of lust and desperation.

"Thanks for waking me up last night, guys..." Sam grunted when he entered the kitchen, his mane of hair messy and his clothes disheveled from having slept in the recliner all night.

Dean looked up from the stove where he was currently making chocolate chip pancakes and suppressed a laugh as he caught a glimpse of his brother in the kitchen doorway.

"Sorry Sam, you just looked so... peaceful, I didn't wanna disturb your slumber," Dean said with a chuckle as he flipped his final pancake onto the plate beside the stove.

"Here, maybe some breakfast will make ya' happy," Dean announced as he stepped around to set the plate stacked high with pancakes on the dining table.

Castiel sat opposite of Sam, his nose buried in the morning newspaper. He set it down as Sam joined the table, looking up at the younger Winchester.

"Good morning, Sam... How did you sleep?" Castiel greeted.

"Fine, Cas... Surprisingly," Sam responded, nodding a thanks as Dean passed him some maple syrup and butter across the table.

Dean came around to sit beside Castiel, stabbing a couple pancakes with his fork and placing them on the plate in front of him.

"Dean insisted we let you sleep, he mentioned you'd spent the day doing research," Castiel added, trying his best to sound nonchalant.

Sam looked between his brother and the angel, trying to figure out if something was going on before shrugging it off.

"Uh... Yeah, I might get back to that after a shower," Sam replied, drowning his pancakes in syrup.

"I gotta finish some work on Baby, you uh wanna help me, Cas?" Dean spoke up, glancing up from his food at Castiel.

"Yes, I can help you," Castiel replied with a nod, resuming his reading of the newspaper.

Dean had Castiel pinned up against the driver side door of the Impala, his hips pressed into Castiel's. The angel moaned into Dean's mouth, the feeling of the hunter grinding against setting his nerves on fire.

Dean covered Castiel's neck in hot, wet kisses as he moved along his jawbone and down his throat, sucking a spot below the angel's pulse point until a bruise formed.

"Dean..." Castiel begged, rolling his hips up to meet Dean's as he grabbed the back of Dean's shirt. Hands dipping beneath the fabric, running up the firm muscles of the hunter's back.

"Cas, fuck..." Dean moaned as his tongue slid across the angel's Adam's apple, causing Castiel to shudder under him.

Dean pulled himself off Castiel, running a shaky hand through his hair in a poor attempt to compose himself.

"Take off your coat," Dean ordered, his eyes dark as he stared into Castiel's own bright blue ones.

Castiel did as he was told and shrugged the trench coat off his shoulders, letting it fall to garage floor. He began to unbutton his white under shirt when Dean's hands stopped his.

"Not yet, angel..." Dean spoke as he reached up, wrapping Castiel's tie around his hand as he tugged it tight pulling Castiel hard against him.

Dean crushed his lips over Castiel's, claiming his mouth in a devouring kiss as Dean kept a tight hold on the angel's tie.

"Dean... Please..." Castiel panted when Dean let up from the kiss for air, his lips puffy and red. Castiel kept his gaze locked with Dean's, even when Dean gave a sharp tug of his tie, choking a muffled moan from the angel.

Dean slipped his other hand down the front Castiel's slacks, past his waistband until rough fingers curled around the angel's stiff cock through his boxers.

Castiel's eyes fluttered closed, head tilting back against the roof of the Impala as another strangled moan escaped him.

"Look at me," Dean punctuated with another tug of Castiel's tie, forcing Castiel to open his eyes to meet Dean's intense gaze.

"How's it going Sammy, you need a break? I made lunch," Dean announced as he casually walked into the library, spotting his brother at a table with various large old books scattered around him.

Sam managed to tear his attention away from the book in front of him, smiling at Dean.

"Yeah, I should probably get some food in me... Dunno how long I've been at this for," Sam responded standing up from his chair, stretching the soreness from his back and legs.

"Come on, Cas and I made burgers..." Dean grinned as he led Sam out of the library.

They entered the kitchen, where Sam was greeted by the sight of Castiel standing by stove wearing a 'Kiss the Cook' apron over his dress shirt, tie and khaki slacks.

"Well, this is certainly... new," Sam said with a laugh as he took a seat at the table, his gaze shifting from Castiel to Dean and back again.

"I figured since I don't eat, I could assist in making sure you two do," Castiel beamed, taking the spatula in hand and flipping a burger patty in the pan like Dean had showed him earlier.

"Uh, thanks Cas, that's very nice of you," Sam responded, a little taken aback as he watched Castiel flip the burgers frying on the stove.

Dean helped Castiel plate the burgers, putting cheese atop them and sticking them into buns before bringing them over to the table.

"Eat up, Sammy!" Dean said cheerfully as he bite into a particularly juicy burger.

Sam took a burger off the plate and took a large bite, mmm'ing around it as the flavors exploded in his mouth.

"Oh wow, that's a really good burger... My compliments to the chef," Sam said happily, nodding at Castiel who was sat beside Dean.

"Oh, I'd wondered if you both would like to watch another movie tonight?" Castiel began, looking between the two men as they ate.

"I would like to see Twister," Castiel added brightly.

"Can't tonight, I gotta get through those books... The sooner the better, but don't let me stop you two," Sam answered with a smile.

"Dean?" Castiel inquired, turning his attention to the older Winchester, who currently had a mouthful of his burger.

"Yeah, sounds like a plan," Dean responded with a nod, tipping his half eaten burger towards the angel.
