A/N: Okay so I've had about five exams in the last week and I really should be studying for the exam I have tomorrow but I couldn't stand to leave it any longer and I really need to know what's going to happen as much as you guys. I hope you enjoy this and thank you for all the amazing reviews and favourites and follows they're truly inspiring. The song that inspired this whole chapter 'Transatlanticism- Death Cab for Cutie', seriously, listen.

Dean's hands shook as he wondered what to do with them, staring at his nervous but determined friend who had his eyes shut tightly as instructed. His mind was racing. This was the most impossibly ridiculous situation he could've pondered getting himself into. Castiel interrupted his panicked thoughts.

"Does.. Does it usually take a while, Dean?" He asked tentatively and Dean rolled his eyes.

"Yeah, Cas, it usually takes ages just, er, hang tight." He shook his head and silently reprimanded him for sounding like an idiot but Castiel was remarkably patient and nodded, standing still, eyes remaining closed.

Dean was now really at a loss. He really wanted to kiss Cas. It was embarrassingly obvious to himself now. He only hoped it was still completely opaque to Castiel. He moved slightly closer to his friend, his breathing erratic, his mouth dry. He fought with his limbs and better judgement as he edged nearer to the other teen, who waited without question, looking far too inviting to resist. He lifted a hand and then thought better of it, stopping himself at the last moment. He was barely inches from Castiel's face now, itching to just bridge the painfully small distance. Castiel shivered, noticing Dean's breath on his lips and gulping down the whimper that wanted to erupt as he attempted to be logical. Why would anyone play a game where the object was to get locked in a closet so they could kiss, how ridiculous. No, it was most likely something much more realistic, or maybe violent.

"D-Dean, are you going to headbutt me?" He asked, sounding adorably concerned and Dean couldn't stop the bubble of nervous laughter that arose from him. He put a hand on Cas' shoulder.

"No I'm not gonna' headbutt you, relax, man." He said gently and saw the way Castiel visibly, if subconsciously, leaned into his touch with a deep exhale, as if it were his anchor. Dean simply couldn't help himself. He let his hand move from Cas' shoulder, tracing a path up to his neck and then to shadow his jaw and hook around his ear. He heard the hitch in Cas' breath and Dean knew he could feel their dangerous proximity.

He watched as his thumb swiped gently across Cas' cheek and Castiel reacted instantly, turning into it almost. Dean opened his hand slowly, cupping his cheek, watching in stunned awe as Cas sighed in something akin to relief at the touch. It was terrifying new territory and Dean was somehow entranced, unsure of what was really happening, but couldn't find the strength to question or put a stop to it.

He experimentally padded his thumb across Cas' lips, they felt soft, a little scratchy, but in a way that made Dean want to investigate which only proved to frighten him more. It was a hypnotising exchange on both parts.

Castiel was painfully ecstatic with the turn this task was taking, even if he was misreading it which, knowing him, he probably was. Reading social signals wrong. He could feel Dean's breath, the warmth of his palm against his jaw, his thumb gently trailing patterns on his lips. He daren't open his eyes, or move, or even breathe for fear of ruining the moment. Finally he couldn't stop himself, he pushed his lips slightly back against Dean's thumb and heard the catch in Dean's breath and then he was gone. Reeling away like he'd been electrocuted.

Castiel cursed himself and tried desperately to calm down his heart as it raced wildly as if late for something and his pulse tripped and fell attempting to keep up. He remained still, his eyes closed. He tried to hear where Dean was in the dark room but Dean gave away no clues. He knew whatever they were required to do, it hadn't been done, and somehow now, he was eager to finish the job.

"Please, Dean, please," He pleaded and Dean bit down on his lip and pulled and ripped at his own hair as he span away from the boy, desperately trying to keep his head. Turning back he just looked at Castiel. Really looked.

This boy was just standing, completely vulnerable, waiting, entrusting in the centre of a dark, cold, oversized cellar closet. He was just so damn easy to want.

Without consciously making the decision to, his feet carried him back over to Castiel. He sucked in a huge breath.

Castiel was in a state of real panic now. He'd crossed some sort of line, some social barrier. He'd misinterpreted what was strictly appropriate and now he was worried he'd angered or disgusted Dean. Or worse, what if he was stood there in silent hysterics, laughing at his idiocy. What if Dean wanted nothing to do with him?

That was when Dean pressed his lips to Castiel's. It was light, gentle, apprehensive, but sweet. Castiel's mind went utterly blank as Dean pulled his lips away after merely a moment. He knew better than to make any rash movement that might spook Dean but was also tempted to jump up and down cheering or dance or just completely tackle Dean to the ground. He really needed to work on his self-control. His power flared up into his lungs and chest as he breathed in a blissful feeling.

Dean was stunned at his own audacity, but more so at the lack of objection from Castiel. He hadn't shoved him away, or been revolted he'd just… stayed. Waiting for Dean to decide what he was going to do next. That was all it took.

He moved forward again and, bringing a hand to pull up Cas' chin, pulled their lips together. This time with more purpose. He meant what he was doing. Cas didn't know what to do, what he was allowed to do, what he expected to do. This was all still part of the task, right?

Dean felt his unsure nature and worked to put him at ease, wrapping a hand slowly around his waist as the hand moved from his chin more insistently to the back of his neck, begging for some reciprocation, but it was all so slow as he moved his lips against Cas' in a way that made it clear he'd stop in a heartbeat if that's what Castiel wanted.

Cas needed no further invitation and pushed his lips back in time with Dean's perfectly, capturing a moment of true ecstasy from Dean. They stayed like that, Dean holding Castiel gently whilst Castiel was unable to do anything other than lose himself in the moment. Of course, had they been outside they might've noticed the lightning striking from the heavens as Castiel kept no check over his powers. One particular crash from outside got through to Dean as he snapped back to reality and realised he was kissing Cas. He was actually kissing Castiel. Properly. He was overjoyed, he never wanted to stop but then one thought made his stomach drop, his eyes open, and his body pull away, not harshly, but with resolve. Castiel moaned at the sudden loss of contact and Dean mourned the loss of his lips already.

But Castiel had a girlfriend. Cas was in a relationship. He was Dean's best friend.

What the hell was he doing?

Castiel finally opened his eyes, gazing at Dean, confusion mixed with hurt in his eyes. Dean was grinding his teeth as he pulled a hand over his face, as if trying to rid it of traces that Castiel had been there.

"Did I, Did I do something incorrectly, Dean?" Castiel asked, his voice thick with emotion. Dean looked to him incredulously and winced when he saw the pain of rejection painted onto Castiel's features.

"No! I just, I can't.. I can't do this, Cas," He tried. Castiel was baffled, he couldn't keep up.

"What can't you do?" He probed. Dean let out a groan.

"This, I can't-" He cut himself off with another groan at his own stupidity. What self-respecting hunter let himself get in too deep without noticing until it was too late.

"I thought this was part of the game, Dean.." Castiel half-lied. It was true, he did think it was part of the game, but he also hoped it was something more. Something real.

"It is. I just.. You have a girlfriend, Cas, I can't, it's…" Dean had suddenly lost the ability to form coherent sentences. Just babbles of apologies and misleading signs that he knew weren't fair to Cas. Castiel blanched when he understood. Dean thought he was being immoral by playing, he really needed to set the record straight.

"Dean, this was what I was trying to tell you about-"

"No, I know, I was a jerk about it, and I'm sorry, I'm an idiot-" Dean objected, not understanding Castiel's train of thought.

"Dean, please listen to me, it's not you it was me, I-" He stepped closer, desperate to explain.

"No, don't defend me, Cas. I was a grade A asshole and I know I just totally crossed a line by not asking if-"

"Dean, stop, you don't understand!" Castiel was getting increasingly frustrated and desperate to obtain Dean's attention as he moved directly in front of Dean, trying to get him to look him in the eye.

"No, I do, I get it, I'm a shitty person, I don't know what's going on with me I really-" Dean continued and with a growl of frustration Castiel pushed himself upwards capturing Dean's lips demandingly with his own. Dean let out a noise of surprise as he was caught off guard by an infuriatingly perfect distraction. Castiel kissed him furiously gripping his shirt in his fists and Dean was genuinely fighting to stop. He tore his lips away.

"Damn it, Cas-" He managed through gritted teeth.

"I don't have a girlfriend. Or boyfriend. Or any other form of romantic partner as of yet." Castiel snapped into his face.

"So stop being so blinded by your moral compass and… just kiss me again." He said with vigour and Dean could've choked on his own air. He stared down at Cas, brow furrowed for a moment.

"You.. You don't.."

"I do not."

"…But you said-"

"I lied."

"..But I thought-"

"Dean!"

Dean took his cue and slammed his lips into the delicious embrace of Castiel's. He wrapped one arm against his waist and his other hand pulled through his hair, writhing it this way and that. Castiel's insides were on fire as his heart ricocheted against his ribs painfully as he kept one fist in Dean's shirt and his other hand made its way to the back of Dean's neck, pulling him even more closely against Castiel shirt as they wildly craved the others touch more with each passing second.

Dean's arm pulled Cas' waist upwards and into him drawing a glorious moan from both boys as they kept as close as they could to each other. The whole thing was incredible and delectable and they could barely keep their hands from gripping and exploring wherever they could reach, both trying to solidify the other, make sure this was really happening.

They'd somehow moved and were tripping slightly as they went but neither could find the energy to care about anything other than the other. Castiel wasted Dean's name on his lips time and time again making Dean's chest pound as his heart thudded in his ear as he was pressed against a stone wall.

Castiel moved his lips from Dean's shattering his world slightly as he moved across his jaw and down his neck, not letting go for a moment. Dean let his head slam back against the wall and the contrast of the cold of the wall and the heat of Cas made some distant unclear memory spark in the back of his mind. He was staggered by the nauseating nostalgia from a memory that was hiding from him. His stomach turned as his head span.

"C-Cas," He breathed. Castiel immediately looked to him and near gasped at the look of fear on his face. It slowly gained more emotion as suspicion was added, which quickly morphed into confusion and then anger, all the while, the human base fear stayed dominant. He suddenly shoved Castiel away, who stumbled back. The memory was fleshing out the more he thought of it. His bedroom. Castiel. Wind. Leaving. Wall. Bed. Black.

"Why can I… Has this.. I remember.. This hasn't happened before, but, but it's, what's…" His breathing started to quicken as his hunter instincts kicked in that something here wasn't right.

"Why can I remember something that didn't happen?" At first he whispered it and Castiel's face paled in true horror as he saw what was happening.

"…You?" Dean saw as the look had dawned on Castiel's face. He knew.

"You did this?" He croaked. Castiel began to shake, his powers flaring like they'd never done before.

"D-Dean, I-"

"What did you do to me?" He demanded loudly. Castiel couldn't respond.

"What did you do to me!" He bellowed and thunder crackled outside from Castiel's fear as he jumped at Dean's shout.

"Dean, it's- I didn't.. I can explain," He whispered. Dean thought he was going to be sick as he finally recognised what'd been plaguing him for a while.

"W-What are you?" His voice shuddered as he stared straight into Castiel's eyes.

"I, I, I'm-" Castiel tried, did he try, but he couldn't. He lifted his hand into the air and lit up the room, the bright white light that erupted from him made Dean back up against the wall again.

"You're- you're an angel!" Dean whispered, heartbroken.

"You know what I am?" Castiel choked, tears falling fast now.

"I… hunt you."

"You're a hunter," Castiel breathed, the light going out as it was his turn to back away.

"But you didn't hurt me." Castiel whined, terrified into the dark.

"I thought you.. I liked you! I thought we were friends." He sounded disgusted that he'd been so easily fooled.

"Dean, we are!"

"You kill people!" Dean yelled and Castiel felt sick.

"No," He said barely audibly. He'd never hurt anyone.

"You were just pretending to be my friend, to, to get close to me, because then you can get to my Dad!" It all made sense in an agonising way.

"No!" Castiel shouted. Dean stormed over to him, grabbing his shirt, raising his fist, ready to strike. It was stupid and uncalculated and in a hunter's eyes, suicide. But Castiel made no defence. He just remained limp, staring into Dean's eyes like he'd just tore down his entire world. He couldn't do it. He couldn't strike Cas. His Father wouldn't have hesitated a second but this wasn't just some angel, this was Cas. He let Castiel fall from his grip and moved away.

"Open that door." Dean snarled.

"Please, Dean-"

"I said open the door!" He raged and Castiel, with a flick of the wrist, opened the door.

"Come near me or my family again and I will kill you." He fumed and with that he left.

Castiel stared after him, feeling as if someone had plunged a ragged knife into his chest and twisted it around sadistically. He thought he was going to retch as he crumbled to the ground.

Dean was a hunter.

Dean hated him. He thought it was all a lie. How had any of this even happened? Choking on his own sobs he heard the storm outside and felt his own power and stretched. Not caring. He raised his head and let out an almighty shout that shook the floor and barrelled the winds and creaked the trees and fractured the windows and he was sure Dean would've felt it and known.

Dean just ran. Through the wind. Through the rain. The lightning. The thunder. The howls of nature. Only it wasn't, it was Castiel.

Don't you stop Winchester. Don't you stop.
