Author's Note: In the last 4 months I re-watched all of Supernatural (seasons 1 through 6) and finished Season 6 this afternoon. I saw something new the second time around (possibly in light of the new supernatural season 7 promos lol) but I accept Cass and the way his character's going. If I don't I'll end up a crying puddle on the floor in a few weeks so I know I have to accpet it lol

Anyway about this fic, it's a one shot and, after a new interest in Crowley/Castiel, I wanted to write a sort 'reason why Castiel said yes to Crowley'. It's got slash and it things get rough so if you don't wanna see Castiel raped then don't read.

"Do we have a deal then?"

The angel's face looked pained as thoughts clearly ran across his mind. He had few choices, either he could give in and surrender to his big brother, losing all the progress he'd made. Or he could fight back. Fighting back required power, required strength that he couldn't muster on his own or ask of anyone else; especially Dean. Dean Winchester, who had given his life to a cause forced on him, who had never stopped fighting even when the world looked dismally broken and ready to crumble. Dean Winchester had lost everything in the last six years of his life and there was no way Castiel could tear Dean away from a family that finally loved him like they should. Like he should have.

Fighting back against Raphael required things that Castiel could never accomplish alone; this deal, this contract he was about to sign with the king of hell, was his only option. It was the only way he could keep Dean safe, and yet... It was also a clear path to pushing him away; to betraying a trust that had been beaten and abused by everyone Dean had ever loved. Cass squeezed his eyes shut and shook his head, "No." His gaze lifting back toward Crowley, "No deal-"

Crowley's hand over the angel's throat cut off the rest of his sentence, an anger burning in the demon's soulless eyes, "You don't have a choice, love."

Castiel struggled to protest but he felt cold metal pressed against his clenched jaw. He recognized it immediately; an angel blade. 'When did he...' Cass couldn't recall when he'd lost it or it had been stolen or what, all that mattered in that moment was what he said or did next. His gaze shifted to the Crowley's eyes again, the desperation present there reminded him of himself, "What will you do?" He choked out the words, his voice ever rougher than usual.

Crowley paused, as if contemplating his next move though he obviously already had something in mind. "I'm gonna change your mind, ducky." He grinned wickedly, "I got a hold of some of that 'holy oil' you feathery bitches are so scared of." With a wave of his hand a bucket slid across the floor to him and one more flick had it splashed all over Castiel, soaking him entirely.

Cass flinched, a skip in his chest told him that fear was getting the better of that arrogance he was feeling. He watched as Crowley waved a lighter back and forth, showing him that his demise was only a flick away. He shifted uncomfortably, his clothing clinging to his chilled skin in all the wrong places, or at least in his opinion.

Crowley had taken notice of Cass' wardrobe and smirked; he moved the blade from Cass' throat and tore it down the front of his shirt. Placing the blade down on a nearby table, Crowley ran his hand down the slick, exposed skin of Castiel's chest. The angel shudders in protest and tries to pull away but the light is lifted close to his face, "Wanna be a crispy critter?" Crowley's voice was soft and gentle though his tone was a frightening thing. Cass shook his head, swallowing hard as his eyes fixated on the tool that could kill him in seconds. "Then DON'T STRUGGLE SO FRIGGIN' MUCH!" He shouted angrily, grabbing Cass' hair and slamming his head into the wall.

Cass' knees gave out involuntarily, his mind racing to find a way out of this. If Crowley would let go of him for a second he could fly off easily, but he knew he couldn't rely on that happening. The demon forced Castiel all the way to the floor, using his weight to pin the angel down. Cass squirmed but he knew the lighter wasn't far off, his blue eyes stared in wide desperation, hoping Crowley wouldn't decide to fry him up anyway.

Crowley had something else in mind, something to bring this angel down from on high. He leaned in close to Castiel's unwilling ear, a foul grin on his lips, "I'm going to defile you, angel, and you're going to like it."

Cass' breath caught in his throat as he turned those fearful eyes on the creature pinning him to the dirty floor. He'd walked right into this, that was his first mistake. His second was following the demon straight to hell, where the King reigned. "No, wait-" Cass tried to protest but his mouth was covered immediately.

"Shut up," Crowley hissed, "You said no, I'm going to persuade you." His devilish smile didn't fade as he ripped the remaining clothes from Castiel's trembling body.

Cass' mind swarmed with thoughts though one came out to him predominantly; what would Dean think? Castiel being defeated, forced down and dirtied like this? Cass had imagined his first time. but only once, and it was with Dean. He shivered against the cold floor as his clothing was discarded. He mumbled into Crowley's hand but the new devil didn't care to listen. He took a firm hold of Castiel's small shoulders and forced him around, pressing his face against the filthy tiled floor of hell.

Castiel gasped as Crowley's cruel hands roamed his cooled flesh, searching out little crevices and nerves to push the angel closer to the edge. "Wait," he pleaded, trying to lift himself to at least be supported by his forearms, "Please wait,"

Crowley paused for a second; Castiel's breathless voice begging wasn't something he intended to put an end to immediately. "What's wrong, angel?" He asked mockingly, roughly gripping the soft skin of Cass' hips and forced his ass upward to present that beautiful entrance.

Castiel winced and clenched his hands into fists, "You don't need to do this,"

"Oh contraire, ducky," Crowley mused, lowering his own pants and underwear. His eyes shifted to the limp dick dangling between Castiel's shaky thighs, a quick lick of his lips told him he wanted a taste of it, though that could wait a moment. "I have to teach you what it means to turn down an offer you can't really refuse in the first place."

With those simple words, Crowley plowed inside. Castiel threw his head back with a cry, as he started to lift himself onto his knees hell's new king slammed him back down. Cass squirmed and whimpered in protest, reaching back weakly to stop the process with little success.

The friction between them was staggering, no lube whatsoever and Crowley wasn't being too nice about it. He leaned back and slammed in again, pummelling the angel's prostate relentlessly. Cass slid against the floor inelegantly with each thrust, Crowley pinning his head to the floor with his free hand, the other ruthlessly slapping his ass and yanking painfully at his stiffening cock. "Somebody likes it rough, yeah?" Crowley growled. He started stroking Cass' swelling member, thumbing at the foreskin playfully.

Cass couldn't help the erection; it was an involuntary reaction due to the ferocious stimulation he was receiving. He wished he had the strength to stop the moans and cries, he really wished he could quit whimpering. But what Cass ultimately wished he could do was keep his dignity, not enjoy it and certainly not come from it. He wasn't able to do any of the things he hoped for.

In unending humiliation, Castiel lay in a pool of his own secretions while Crowley had his way with him, pounding him repeated against the cold, filthy floor. Tears fell from those baby blues as an image of Dean living comfortably with a loving girlfriend came to mind. Castiel sniffled audibly, his body trembling violently from the cold, pain, and sobs. "Please..." he managed to choke out through staggered breaths, "Please stop... I'll do it, I'll work with you. Please stop." Cass sobbed erratically, turning his head to face the demon who seemed to have paused to listen to him.

Crowley slammed him one more time, ripping a scream from Castiel's hoarse throat and splashing a white, hot mess all over his anal canal. "Alright," he sighed, pulling out carelessly and watching the mess drip out of Castiel's used, ruined ass. "Let's discuss details then."

Cass lowered himself to the floor, attempting to collect himself, though the harder he tried the more he fell apart. He let out a distressed cry; his eyes squeezed shut as he curled into himself. Crowley knelt next to him and lifted him up so they were nose to nose, staring into one another's eyes. Castiel sniffed, his shaking hadn't stopped but his eyes remained locked with the demon's. Crowley was oddly attracted to the tear-stained face, those pudgy cheeks and those hunger-inducing lips. He leaned in and took a taste of them, passionately and gently as if consoling the abused angel.

Cass' body shook though Crowley's arms wrapping around him gave him comfort, at least someone would have him now that he was defiled, disgusting and unclean. Cass' arms flung around Crowley's neck and the demon took him into his lap, comforting a desperate soul. After their lips separated Castiel lowered his head against Crowley's chest, curling into the man who hadn't looked at him like he was the filthy, pathetic thing he felt like. "I'm sorry," Cass whispered, his voice sounded ruined and broken.

"No worries, angel." Crowley spoke softly, reassuring. "It's over now, you'll be fine."

Castiel's hand closed on Crowley's shirt, clinging to him. Cass couldn't stop thinking about Dean, how he'd walked away from the hunter. He knew this path would hurt Dean, he knew he had to keep it a secret for as long as possible. If it all worked out then he'd be rid of the threat in heaven and could go on with life like before... couldn't he? Would Dean have him around, now that he was deflowered and used? Cass shook his head; he never wanted Dean to know about this, what happened here. He'd rather Dean think him a liar and a betrayer than look at him that way.

'I love you Dean.' He though helplessly, wishing his thoughts could reach his human, 'I wish I could tell you... I hope you won't hate me when this is all over.' Cass squeezed his eyes shut and curled further into the warmth of Crowley's chest, trying to imagine he was in Dean's arms instead.

Remember, reviews are made of love! So leave me some :)
