Kind of nervous about this one. I've never been comfortable writing sex scenes, especially m/m, so my apologies if it's awful. I'm using this fic to push myself into writing things outside of my comfort zone. This is actually the first AU fic I've ever written. :D

Castiel's mind was in turmoil as he followed Dean across the street to the Winchesters' house. He was overwhelmed by all he found out, and he was torn between wanted to discuss everything with Dean or drowning his problems in vodka.

A knot formed in his stomach as he realized that he couldn't discuss things with Dean. Sam had not yet had the chance to talk to his brother about Adam and Castiel was afraid that it would come up. He didn't want to lie to Dean, but it wasn't his place to tell.

They entered the house and went to the kitchen, Castiel sliding into a chair while Dean headed to the refrigerator.

Castiel had only been over to Dean's house a few times since they decided to become 'more than friends'. The mechanic, despite having more help at the shop, put in a lot of hours. Castiel worked late nearly every night to help Gabriel keep the bakery going. They were both in the kind of business that didn't close on the weekends, or ever really, and finding time to spend together was not easy.

A quick lunch here and there was pretty much all they got, as Gabriel, Sam, and Claire usually ate dinner with them. There always seemed to be people around, and neither was very comfortable with PDA. The intimate moments they had shared since their kisses at the creek had been nothing more than a few chaste kisses and longer than appropriate for 'just friends' hugs.

"You want to drink it straight, or mix it with something? I think Sammy has some juice in here somewhere," Dean said, leaning over and searching through bottles at the bottom.

Castiel was unable to respond, mouth going dry at the sight of Dean's rear, work-pants stretched tight as he leaned further into the refrigerator.

No, Castiel didn't want to talk or drink. He wanted to do something else.

Dean turned with a triumph smile as he brandished a half empty bottle of orange juice, but jumped in surprise when he saw that Castiel had come over to stand right behind him.

"No Dean, I don't want to drink," Castiel said, intentionally lowering his voice. He smirked when Dean gasped and flushed at the sound.

Castiel grabbed the bottle of juice out of Dean's hand and put it back into the refrigerator. Then he turned and backed the mechanic into the counter attacking the other man's lips as his hands ran up Dean's arms to caress his shoulders.

Dean froze for a second, then moved his hands to rest on Castiel's waist, tugging him closer by his belt loops. Castiel sighed in approval and continued his assault on Dean's mouth.

After a moment Dean had to pull back and take a breath. He let out a groan as Castiel began trailing wet kisses down his neck to the base of his throat.

"Cas, don't you think..." he began, but Castiel cut him off with another deep kiss to his mouth, nipping at his lower lip when he pulled back a moment later.

"I don't want to think, or talk, or even drink," he murmured, slipping a hand down to caress that perfect ass he'd been ogling a few moments before.

"What do you want?" Dean asked huskily. His green eyes closed with a moan as Castiel return to suck at his neck.

Castiel thought of Amelia, and how fragile she had acted during sex. She had always immediately protested anything that hinted at him being aggressive or taking charge in any way. He hadn't minded letting her lead things mostly, but occasionally he liked to try new things. She would never go for it. As if Castiel would ever hurt her or do anything she didn't want him to.

He resolutely pushed her from his mind, deciding to let go and do what he wanted.

"You. I want you," he said, then bit down hard enough to bruise. Dean let out a strangled gasp, and Castiel let go and stepped away afraid if he'd crossed a line.

Suddenly he was being manhandled down the hall to the living room, Dean holding tightly to his arms practically dragging him along. When they reached the room, Dean started ripping Castiel's clothes off. His coat fell to the floor followed by his dress shirt, now missing a few buttons. Before he could protest the rough treatment of his clothes, Dean pushed him down on the sofa and dropped to his knees between Castiel's legs.

"Damn, Cas, you have no idea how long I've wanted to do this," Dean said with a moan, moving his hands to unzip the other man's pants.

Castiel only just stopped himself from protesting, remembering how repulsive the idea of a blow job was to Amelia. He made himself stop and study Dean's face. He did not look repulsed at all. In fact, Dean looked like a kid at Christmas as he looked up at Castiel with a grin and saucy wink.

All thoughts flew from Castiel's mind at the feel of the hot wetness around him. At some point he slipped his hands into Dean's short hair, first gently rubbing his scalp then tugging as the sensations became more intense.

The harder he tugged, the more Dean moaned, obviously turned on by the rougher treatment. Still, Castiel did not want to go too far and took a breath to try and regain some control. As if in response to feeling Castiel pull back a little, Dean suddenly moved in closer.

It was pretty much over for Castiel at that point.

He would never have guessed what a turn on it would be to taste himself on Dean's lips as they shared a wet, sloppy kiss.

With Dean's help, he managed to stumble his way into the bedroom flopping down on the bed as the other man continued to remove Castiel's clothes and then stood up to remove his own.

Castiel watched Dean, struggling against the exhaustion that threatened to claim him as the long day caught up to him.

Dean seemed to understand, and soon they were both in bed sharing lazy kisses and caresses. The mechanic could do nothing but moan and writhe as Castiel whispered encouragement between kisses and small bites to Dean's throat. He did not last long.

After taking a quick moment to clean themselves up, they were snuggled in bed with Dean spooning Castiel. He vaguely remembered Dean asking him a question, but sleep quickly claimed him. It was the best night sleep he'd had in months.

Dean and Castiel spent a blissful morning together lounging in bed then sharing a shower. They both cooked breakfast made a huge mess, cleaned it all up, then took another shower together. It was after ten before Dean dropped Castiel off at the bakery.

Castiel hesitated, taking note of the small crowd of people milling around shops then looked back at Dean and shrugged. Giving Dean a smile that rivaled the sun, he leaned over and kissed him quickly but firmly.

"See you tonight," Castiel said and turned to leave.

Dean looked at the people around them. A couple of women were staring at him in open mouthed shock. One older man and woman were smiling at him, and no one else seemed to be paying any attention at all. He waved at the 'shocked' ladies and headed for his shop.

Claire greeted him with a knowing smile, and started giggling at him later when he began whistling as worked. The day passed smoothly, and soon it was time to start locking up and head home.

Garth had been working very hard, and Dean was planning to give him a promotion and a raise. The fact that he had come in this morning after receiving Dean's text twenty minutes before time to open really helped his case.

He sang along to the radio on the short drive home, and then headed inside to change before he went to the Novak's for dinner. He was surprised to find Sam waiting on him in the kitchen.

"Hey Dean, how was work?" His brother asked, peeling the label off a beer bottle.

This couldn't be good.

"It was fine Sam, what's going on?" He asked, crossing his arms and leaning against the doorway.

"I have something to tell you and I'm not sure how you're going to take it..." Sam began.

"Is this about me and Cas? Look, I'm sorry you felt like you had to stay over there last night..." Dean started but Sam interrupted him with a laugh.

"No, Dean! I'm perfectly fine with you and Cas hooking up over here. Just give me warning in the future if you can. Gabe has offered to let me keep some clothes over there just in case."

Dean's entire posture relaxed.

"Oh. Well, better pack a bag tonight Sammy," he said, giving his brother a wink.

Sam huffed and Dean grabbed a beer out of the refrigerator before joining his brother at the table.

"So, if it's not about me and Cas, is it about you and Gabe? Cause you know I'm cool with it right?" He said, popping the bottle top off.

"What? No! Gabe and I are just friends," Sam insisted, but turned very red. Dean just grinned at him. "Sure, okay. Just friends..."

Sam cleared his throat and frowned.

"No Dean, I'm trying to tell you that we have a little brother."

"What?" Dean blinked, sure he hadn't heard that right.

"I went by Dad's grave on my lunch break yesterday and he was there. His name is Adam Mulligan. Apparently Dad met his mom at a bar when he and Bobby went on that fishing excursion in Louisiana a couple of years after mom died."

Dean took a moment to process that before snorting.

"Yeah right. What's he after, money?" Sam frowned.

"Right, cause we're loaded," he said, sarcastically.

Dean took a swig of his beer, not sure what to say. The brothers sat in silence for a moment.

"We really have a little brother?" Dean finally broke the silence several minutes later.

Sam nodded. "I'm pretty sure he's legit. I mean, he looks a lot like Dad in the face."

Dean nodded absently, feeling a wave of fresh pain that came from missing his father.

"So what's he want?"

Sam shrugged.

"I think he wants to know us. His mom just passed and he only found out about who Dad was from a letter she left him. He's nineteen. That's really all I know. That and he's supposed to have dinner with us Sunday night."

"Dinner? Here?" Dean asked, an unknown fear gripping at him.

Sam shook his head.

"No, I think it would be better to do it at Gabe's. He, Cas, and Claire can take some of the pressure off. Unless you want it to just be the three of us?" Sam asked, suddenly unsure.

Dean frowned.

"No, I like your idea better," he admitted.

The sat in silence again after that. Sam broke it with a sigh.

"I'm sorry for knocking the smile off of your face," he said.

Dean waved it away, focusing on the uncomfortable knot that had formed in the pit of his stomach.

"So, I should still pack a bag? You and Cas want the house to yourselves tonight?" Sam asked.

And just like that, Dean's smile returned.

A/N: Next chapter will be the family dinner. Plus Claire's promised 'run-in' with Gavin.

I'm not sure when it will be up. I've started a couple of other fics, which will slow this one down a bit, but I promise I won't abandon it. I'm actually working on a new BBT fic, gasp! ;D
