Summary: Human!AU. Castiel never expected to see Dean again, the man from one marvelous one-night stand. However when Dean walks back into Castiel's life on the arm of his twin sister, Anna, a year later, Castiel's world is turned upside down as he realizes just how much Dean affects him. UPDATES SUNDAYS

He was never supposed to see him again. It had been a one-time deal borne out of loneliness and one too many fruity drinks that had left him with more bad ideas than good ones. While the encounter had been enjoyable and an experience that Castiel looked back on fondly, it was also one that was never supposed to see the light of day, something he could have kept secret and safe from prying fingers and judging eyes.

Dean had apparently not gotten the memo and had sauntered back into Castiel's life as easily and confidently as he had sauntered into his bed over a year ago. Castiel had thought for a moment that the man had forgotten him, that his secret would be safe, that he could keep that night to himself. But when Dean's green eyes met his they lit up and the smile he had been wearing turned into a knowing smirk, one that remembered how Castiel had felt, had fallen apart beneath his hands, and Castiel knew that his secret would no longer be just his. When Dean crossed the street to stand directly in front of him, eyes full of mirth and a smile that begged to be seen, to be kissed, and uttered Castiel's name in a way that had his knees buckle, Castiel knew his world would never be the same again.

Anna had been the reason for Dean's sudden appearance in Castiel's life, both a year prior and then now. Castiel found it kind of funny that his sister had brought them together considering if she knew how much Castiel knew of Dean and vice versa, she'd probably flip a shit. At least Castiel was sure he'd find it funny were it not for the fact that his mind was yelling 'jump ship!' while his hands were begging him to drag Dean to the nearest bathroom and have his wicked way with him.

The circumstances for both meetings were quite different. Castiel had met Dean at a bar over a year ago driven for some much needed alcohol by Anna's betrayal. Walking in on his twin sister riding his then boyfriend had left a nasty taste in his mouth which had him downing margaritas courtesy their elder brother, Gabriel, until Dean had made his way over to the bar and Castiel decided to get well and thoroughly fucked. Dean had done his job marvelously and Castiel had spent the night very satisfied and well distracted from the failed relationship he'd face in the morning. Castiel had thanked Dean for a great night and left, knowing he'd never see the other man again.

Fast forward a year and Castiel was staring at Dean whose arm was wrapped lightly around his sister's waist as if it belonged there. Castiel had been waiting to meet his twin's mysterious boyfriend for the past two weeks when he first learned of him. When Anna had told him that his name was Dean, Castiel had never thought for a second that it would be his Dean. Now Castiel wished he had asked more questions, been better prepared for the possibility. He wasn't' prepared. Not at all.

"Castiel." He cringed at his knees and shifted his weight, trying to hide the effect Dean's voice had on him. Judging by Dean's expression, the subtle shift in his smile, he wasn't fooled. Anna however remained unaware and beamed at Dean before turning her bright gaze on Castiel as Dean offered his hand. "I've heard a lot about you." Castiel stared at the proffered hand before letting his gaze travel up to the face of its owner. Only when he felt a gentle shove at his shoulder and his brother Gabriel whispering his name did Castiel take Dean's hand and shake it, hiding his disbelief behind a blank face.

"I'm so glad I finally have my two favorite people in the same room!" Anna exclaimed, adding a quick "three!" at Gabriel's hum as Dean gripped Castiel's hand tightly. He held on longer than necessary and Castiel's fingers tingled long after he let go

"Yeah," Dean replied, slowly tearing his gaze away from Castiel to look down at Anna by his side. "It's nice to finally meet you guys, you're all Anna talks about." Dean smiled at Anna, pulling her closer before returning his gaze to Castiel, barely glancing at Gabriel who huffed and nudged at Castiel's shoulder, pulling a lollypop from his pants pocket.

"Wish we could say the same about you," Gabriel snarked, slipping the sweet between his teeth and twirling it, closing his lips around the candy and sucking before pulling it out with a loud pop. "We only just learned about you two weeks ago and you've been dating my sister for what," Gabriel paused and turned his attention to Castiel who tore his stare away from green eyes and looked at his brother, frowning. "Four months? Did she say four months, Cassie?" Castiel's frown deepened at the nickname but he answered with a nod. Gabriel smirked and turned back to Dean whose grin had faltered slightly.

"Is this where you give me the hurt my sister and you're dead speech?" Dean asked, challenging. Both Anna and Castiel cringed as Gabriel's smirk melted into a snarl.

"No, this is where I pum-"

"Gabriel!" Castiel grabbed his arm, pulling the shorter man away from Dean who had stepped back, surprised by the sudden malice. Gabriel turned to Castiel, eyebrows raised before popping his lollypop back into his mouth and shrugging. Castiel sighed and turned towards his sister. "We should get a table," he suggested, gesturing to the restaurant they stood in front of. Dean nodded, eyeing Gabriel warily who chomped down on his lollypop and began crunching loudly.

"Shouldn't we wait for Balthazar?" Anna asked. Dean looked down at Anna questioningly and she answered "Castiel's boyfriend," with a sweet smile. Dean looked over at Castiel then, frowning slightly as Castiel shook his head.

"No, he's currently working." Gabriel huffed and flicked the now bare lollypop stick into the street before shoving his hands into his pockets and bouncing lightly on his feet.

"Come on. I'm hungry and I want a drink." He hauled the door open and swept his free arm outward. "I know I'm not the only one," he quipped, directing a pointed stare at Castiel who frowned and entered the building, the others following suit. It was going to be a long night and Castiel knew no amount of alcohol would make it any better.

"Well that was a barrel of fun!" Gabriel flopped down onto the couch and Castiel wasn't surprised to see his brother biting into another sweet, by the looks of it, chocolate. Castiel shrugged out of his overcoat and hung it on the small coat rack by the door, dropping his keys onto the sideboard and making his way into the small kitchen. "How you managed sex with that is beyond me."

"It was easy," Castiel replied, his lips turned upwards in the first smirk Gabriel had seen from him all night. Gabriel shook his head and stared at his brother. Castiel slunk about the kitchen, pulling a beer out of the fridge and downing half of it within the first gulp. He stood at the counter, running a hand through his hair before pressing his fingers to his closed eyes.

"Are you okay?" Gabriel asked. Castiel nodded, picking up his beer and grabbing another before making his way into the living room. He handed Gabriel the second beer and sat down on the overstuffed chair, taking a small swallow of his own. "You sure?"

"Yes Gabriel. It was just a shock is all." Gabriel hummed and nodded, watching as Castiel slumped back in his chair, toeing off his shoes and propping his feet up on the coffee table, wiggling his socked toes.

"I noticed he didn't seem that shocked to see you." Castiel frowned and stared at his feet.

"You think he knew? Before?"

"Well yeah. Not many people running around with the name Castiel out there," Gabriel huffed, sitting up on the couch. "Probably knew the first time Anna mentioned you which brings up a whole slew of questions." Castiel sighed and shook his head. He would rather not think about those questions and their possible answers at all.

Gabriel frowned and leaned back into the couch, eyes roaming the apartment, cataloging Castiel's books stuffed on the multiple shelves, and cluttered on the coffee table, the pictures hung up on the wall and the well stocked bar off to the side, Balthazar's touch along with the 50" flat screen, DVDs, and sound system. Gabriel looked back at his brother. "How is Balthy?" Castiel whipped his gaze to his brother at the sudden change of subject, frowning.

"Not tonight, Gabe," he sighed, pressing once more at his eyes as if to hold back a migraine. Gabriel continued as if he hadn't noticed.

"Don't Gabe me. Where is that asshole? You could have used him tonight. Shoved him in the oaf's face." Castiel rolled his eyes and took another swallow of his beer. "Isn't he supposed to be your boyfriend? He does live here, right?"

"Yes he does and you know we're not monogamous, Gabriel."

"Only because he doesn't want to be! You know you would be, you basically are!" Castiel finished his beer, refusing to meet his brother's gaze. "When was the last time you had sex with someone other than Balthazar?" Castiel's frown deepened, not liking the answer he was about to give.

"Dean." Gabriel's eyes widened, before he nodded and continued on.

"Okay and when was the last time Balthazar had sex with someone other than you?" Castiel sighed and looked up towards the ceiling.

"I suppose that's what he's doing right now." Gabriel nodded once as if Castiel had proven his point. Castiel shook his head and stood, making his way back into the kitchen to throw his empty beer bottle into the recycling. "I don't see your point."

"My point is you dump that ass you call a boyfriend and find a better one, one who's gonna treat you right and incite a bit of envy in that douche you couldn't keep your eyes off of tonight. And yes I noticed. Pretty sure he noticed too."

"You don't think-"

"Anna?" At Castiel's nod Gabriel shook his head. "No, she didn't notice. Too busy staring at him like the sun shown out his ass." Gabriel frowned and swirled his beer within its bottle. "You two are a lot alike. It was creepy watching you two fawn over him. Same expression, yuck. I don't see it." Gabriel finished is beer and looked over at Castiel who was wiping down the already spotless counters, his eyes taking on a far off look that had Gabriel jumping out of his seat and bounding into the kitchen. "No Cas- bad idea. And this is me telling you it's a bad one." Castiel looked up at Gabriel, his face the perfect mask of confusion but Gabriel knew better. "I know what Anna did was shitty. What happened with her and Crowley-"

"Don't." Castiel growled. Gabriel sighed and nodded.

"Still. Getting back at her through Dean a year later is a bad idea and not one that would end well for anyone, including me."

"I wouldn't-" Castiel began, his expression one of revulsion before Gabriel cut him off with a wave of his hand.

"Yes you would. Maybe not intentionally but you would. Do you really want to go through that again? She was miserable without you and you were miserable without her. And you'd be doing it out of spite Cas, not because you got drunk and her boyfriend was a dick." Castiel frowned. What Gabriel said was the truth. He had gone three months without speaking to Anna and it had sucked, losing them both. He realized he wouldn't wish that hurt on anyone, especially Anna.

"You're right."

"Damn straight I'm right!" Gabriel exclaimed. Castiel sighed and stared down at the granite, frowning. "I guess there's still the issue of the fact that you and Dean had sex. That shit is not going to stay secret forever." Castiel nodded.

"I guess I'll have to tell Anna. She won't be happy."

"That's an understatement!" Gabriel laughed, "Personally I think you should tell her. She'll drop Winchester in a heartbeat once she learns that juicy tidbit." He chuckled gleefully.

"I don't want to break them up. Maybe I should talk to Dean, convince him to tell her." Gabriel's face fell as if Castiel had dashed all and any hope of fun.

"Don't want them to break up? You're telling me you'd be fine if they stayed together, got married, had kids?" Castiel blanched. "That's what I thought. Better that they break up now. Besides, the honeymoon phase should be over soon. It'll definitely be over once she finds out about you two." Castiel huffed. He knew Gabriel had a point. However he also noticed Anna at dinner, saw how she looked at Dean, how she beamed. It had been a while since he had seen his sister so happy and Dean seemed to return her feelings. It had been hard to watch at some points and confusing when Dean turned his gaze on him. He would have to talk to Dean and perhaps if they broached the subject with Anna carefully, no one would end up hurt.

"I should talk with him."

"Who?" Gabriel queried. "Dean?" At Castiel's nod Gabriel threw his hands up as if in surrender. "You're hopeless, you know that? You're walking yourself into a whole mess of trouble and while I am all for trouble this is not one I want to see you in." Castiel shrugged in answer. His brother was probably right. "Just be careful, okay? Don't get in too deep. And for the love of all things sweet and delicious do not fall in love with him."

"He's with Anna, Gabriel! And besides I am quite happy with Balthazar." Gabriel raised an eyebrow signaling his disbelief.

"Don't lie to me Cassie, you were never good at it." Gabriel heaved a heavy sigh and made his way to the door, digging out a jolly rancher from his pocket. "Just be careful. I would like to avoid another family breakup." Castiel followed him to the door, watched as he unwrapped the sweet and popped it in his mouth. Gabriel turned to him and looked him over, sighing yet again at whatever he saw. "You're my favorite, you know. I'd hate to actually have to take a side in the fight, especially if it wasn't yours."

"You're not supposed to have favorites, Gabriel," Castiel chided but the corners of his mouth quirked upwards.

"Everyone has favorites! Dad loves Michael, Mother's is Luci, and due to the freaky twin bond you and Anna have, well-" Gabriel faded off looking at Castiel and shrugging his shoulders as if to say 'what can you do?' Castiel let himself smile fully and wrapped his shorter brother in a much-needed hug.

"You are my favorite." Gabriel chuckled and pulled away.

"You're lying again but I appreciate the sentiment all the same." He huffed, shaking out his arms as he turned and opened the door. "Now to go home alone, with no one to hold me close," he lamented. Castiel chuckled, closing the door to his brother's crooning voice.
