Chapter One:

A stifled murmur echoed the dusty room, gaining the attention of the only other occupant. The floorboards creaked lightly as the person walked over to the one that was just coming around. He tilted his head slowly as a faint smile graced his lips. They could now finally begin. He walked away slowly, putting space between them again.

Castiel groaned as he opened his eyes. His head spun and he blinked rapidly, trying to focus his vision. He knew there was someone near him although he had no idea who it was or even where he was right now. Before he had been observing Dean from a distance. He hadn't been doing much, sitting on his bed, drinking a beer. Castiel didn't want to disturb him. So he just watched.

Then things had quickly gone wrong before he even noticed anything had happened. It took him by surprise, caught him off guard. Nothing had seemed out of the ordinary though and then everything turned dark and black as night.

The other person in the room cleared his throat, gaining his attention. As his head began to clear he noticed he was sitting on a chair with his arms shackled behind his back and his legs were also shackled together on the floor. Castiel slowly moved his head and looked down at his feet. He could clearly see the thick, silver shackles that encased his legs.

Within seconds, Castiel felt his heart sink when he saw there were inscriptions on them that were glowing a faint blue. The inscriptions were clearly markings used to entrap an angel. Castiel instantly felt a wave of panic rush through him. As his head cleared further he saw he was in a room, filled with nothing more than a few rickety chairs, a table and a couple of other things that Castiel would rather ignore.

Castiel wasted no more time and he began struggling in a vain attempt to free himself. Laughter filled the room, apparently more than amused by his efforts.

'Now, now, Cas, you know as well as I do that fighting will not work against those shackles. Especially not with the inscriptions that I have used,' came a very familiar and disturbing voice.

Castiel closed his eyes at the sound but opened them quickly when the floor creaked. The person in front of him bent down so they were at eye level and Castiel felt his chest tighten with fear. It was Sam. He was dressed in his usual attire, jeans, shirt and jacket. A single strand of hair fell into his eye as he watched Castiel. His lips curved into a knowing smile but this one was different. There was an air of confidence surrounding him, as if this situation was normal.

'I'm so glad that you're finally awake,' said Sam quietly as he continued to looked down at the angel. Castiel looked away and when he refused to meet his eye again, it made the anger within him boil. Sam lashed out, kicking the angel's vessel in the shin.

'You may be an angel, but don't think you're any better than me,' Sam spat angrily.

Finally, Castiel looked up at Sam again. His blue eyes were large and innocent looking as they narrowed and his head tilted in confusion. 'I don't understand,' he said calmly.

Sam laughed. 'Yeah, I'm sure you don't.' He paused. 'Lately I've been questioning what's right and what's wrong because lately that invisible line seems to have blurred somewhere in time.' Sam paused again before he moved and walked around Castiel, looking down at the angel in pure contempt. 'Although I'm sure none of it escaped your notice.'

'So, Cas,' he continued in an almost friendly tone. 'Tell me, am I evil? Is what I'm doing wrong?'

'Yes,' Castiel said without any hesitation.

Sam came to a stop in front of Castiel and slowly, he reached behind his body and slipped a shiny, silver knife from his back pocket. Castiel noticed but said nothing. Sam brought the knife forwards and pressed the flat part of the blade against Castiel's pale cheek. He gasped lightly at the coolness of it but he still said nothing.

Castiel's eyes flickered down to the blade as the tip was dragged up beside his eye. The blade contained similar symbols as the shackles and they glowed a faint, shimmering blue. Castiel's face hardened. It was then that he realised what Sam had in mind.

'Why are you doing this, Sam?' he asked calmly.

'Because I want you to tell me things,' Sam replied. 'And I don't want Dean around and I don't want you lying to me.'

'I am an angel of the Lord,' Castiel stated firmly, his eyes flaring momentarily. 'I would not lie. It is a sin.'

'So is lust, Cas,' Sam stated cheerily. 'Or have you forgotten that?'

Castiel shook his head as he lowered it, resting his chin upon his chest. He sighed lightly. Sam chuckled carelessly as he exhaled. 'Forgetting bible classes, Cas?' asked Sam mockingly. 'For lust is a shameful sin, a crime that should be punished. It is a fire that burns all the way to hell. It would wipe out everything I own.' Sam paused and licked his lips slowly. 'True, is it not?'

'Perhaps,' said Castiel quietly. 'What you are doing is also a sin, Sam. Torture is sin... Therefore all things whatsoever ye would that men should do to you, do ye even so to them...'

'But you have tortured before, Cas,' said Sam slowly.

'For reasons that were not my own,' he retorted quickly. 'If I had the choice I would not have done it. We are supposed to love thy neighbour.'

Castiel's statement made Sam stop for a moment. He lifted the blade off Castiel's face before plunging it into his shoulder deeply. Castiel cried out in agony as the in scripted blade pierced his flesh. The searing pain didn't leave until the blade was pulled from his body. Sam dropped it to the floor carelessly. Castiel glanced up. Something had changed.

Sam's eyes darkened. Castiel knew there was no demon within but he knew something was different, wrong. Sam's still body stiffly turned and glanced towards the other side of the room before he did anything else. Slowly, he casually walked around Castiel's immobile form. Castiel suddenly didn't like where this was slowly heading.

'Now, Cas, tell me, what are your angel plans concerning me?'

'Angel plans?' Castiel said, wondering if he heard correctly. 'I have no angel plans concerning you, yet.'

'Yet?' questioned Sam. 'I suppose none of you want me around. I remember the look you gave me after I killed Alastair.'

'I will admit, I was disturbed by your display of power and skill,' Castiel disclosed. 'But at this present moment we have no orders to do anything to you.'

'Hmm...' Sam hummed.

His anger exploded throughout his chest and he punched Castiel square in the mouth, splattering his hand and the angels face in blood. Castiel's head shook from the violent force but he quickly focused upon Sam again.

'What do you plan on achieving with these methods?' asked Castiel, spitting out the warm blood that rapidly filled his mouth. Sam's only answer was the beating that followed.

When Sam had finished, he was out of breath and panting. He wiped the sweat from his forehead and looked towards Castiel. He had been knocked to the ground in his chair and the angel's face was almost obscured by his blood and the bruises around his eyes and mouth came up quickly.

Sam walked away from Castiel, rubbing his sore hand and muttering to himself. When he returned, something else seemed different. He gently picked up the chair and placed it back on all fours. He faced Castiel and slowly wiped the blood from his face with his hands, smearing it onto his jeans.

'Sam,' Castiel gasped. 'What... what are you doing?'

'What do you mean?' Sam replied, feigning innocence, his hazel eyes wide. 'I was initially going to force you to tell me everything I wanted to know but I figured, I have time, it can wait and I can have a little bit more fun.'

'Where is Dean?' Castiel asked, trying to get Sam to think of something else.

Sam's head lowered as he chuckled throatily. 'Dean?' he questioned as though offended. 'Yes, of course. You don't like being alone with the boy with the demon blood.'

'I didn't mean it like that,' Castiel whispered gently.

'Yeah,' said Sam heavily, not believing his ears. Sam chuckled under his breath, his mind obviously focused upon something new. He moved closer to Castiel and slid himself onto his lap. Castiel's breath caught momentarily, slowly realising what Sam's true intentions may have been, but he didn't want to believe it.

'I watch you, Cas,' Sam said slowly. 'The same way that you watch Dean. Oh, don't be like that Cas. I know the looks between the two of you. It's almost sweet.'

Sam slowly ran his hand down Castiel's arms to the restraints around his wrists before leaning closer to him, bringing his face mere inches from Castiel's.

'I remember when I first met you,' he started softly. 'I felt so overwhelmed, so in awed by your presence that I almost felt pure. Before long all I could think about were all the things I wanted to do to you. I've wanted to be alone with you but for some reason, it never seems to happen. I never realised how stubborn you would be.'

He lifted his hand and slowly ran one finger, almost lovingly, down the soft skin. 'I've always known that you were a good little soldier.'

Sam leaned forwards to place a kiss on his lips, but Castiel quickly turned away, his heart hammering in his chest with trepidation. Sam merely chuckled again. 'Boy, you are stubborn, aren't you? Well, that's okay, I guess. But by the time I'm done with you, I promise you will be begging me for more.'

'What... what do you want?' Castiel asked shakily.

Sam tilted his head as his face broke into a broad grin. He studied Castiel's face, concentrating hard as though he were trying to solve something puzzling.

'You should already know that, Cas,' replied Sam. 'I want you to look at me like you do with Dean... I am curious however to know, how far have you two gone?'

Castiel stuttered. 'What are you talking about?'

'You may be an angel but I know you're not so innocent,' said Sam with a smirk.

'There is nothing going on with Dean,' Castiel said more confidently.

'Oh, really, and why is that?' asked Sam, feigning curiosity.

'This body is not mine. I would never force Jimmy to bear witness to... my desires,' he whispered under his breath.

Sam laughed. 'But you're not denying your feelings,' he said, his eyes twinkling. 'I'm amazed. I truly am. You have guilt and much sin.'

'Love in any form is not wrong...'

'But with another man is,' said Sam interrupting. 'But I suppose I can sympathise. I have, experimented, I guess you could say and it's quite interesting.'

Sam sat up straighter on Castiel's lap and he sighed. 'There are many human things you have yet to experience. Trust me when I say that I am more than surprised that Dean has not offered himself or jumped at you yet. His loss I suppose.'

Sam slowly got back to his feet and he moved across the room, quickly coming back into view, dragging a large, silver table with him. Castiel's blue eyes turned wide.

'Sam, this is not necessary,' said Castiel desperately. The realisation of what was really going to happened weighed him down heavily. Castiel licked his lips lightly, waiting for Sam to say something.

A strangled cry echoed the room as Castiel was forced from the chair and pushed onto the silver slab. Before Castiel had no time to think as the shackles removed themselves and strapped him to the table. Castiel lifted his head to see Sam standing there, with his arm stretched out at him. He didn't think the younger Winchester would go this far.

Sam panted for several moments before striding towards the silver table. He swung one leg over Castiel and straddled his waist, getting into a comfortable position. Within seconds, Sam ripped the trench coat from Castiel's body and threw the tattered fabric to the floor; his shirt and tie quickly join it. Castiel gasped at the sudden rush of cold air that surrounded his skin and the feeling of the cold table beneath him.

He let his fingers trail across the bare skin causing a tingling sensation. Castiel then felt real fear flood him. 'Please, Sam, stop this,' he whimpered.

Sam glanced up at him seductively. 'Oh, come on Cas, you don't really want me to stop. You want to know what it's like to be human and I'm going to show you. It feels so good. Trust me.'

Castiel shook his head desperately. 'No! It's wrong. Stop this now!'

'I don't think so, my little angel,' said Sam gently. 'We cannot stop now, we're just getting started.'

Sam straightened for a moment and lifted the hem of his shirt and slid the fabric up and over his head, revealing his tanned, musclier chest. The corner of Sam's mouth curved knowingly. 'I saw that, Cas,' he said seductively. 'You naughty thing you, watching me.'

His smile quickly filled out when Castiel turned his head, pink tingeing his cheeks in slight embarrassment. Sam's eyes twinkled as he reached between them and began stroking the front of Castiel's pants, causing the angel to gasp at the sudden sensation.

'Sam! Stop!' he pleaded, trying to shift but unable to.

His heart hammered in his chest. Why was Sam doing this? He couldn't get his head around it. It didn't make any sense. He also didn't understand these strange sensations running through his body. He believed it to be desire, lust, need but Castiel knew that it wasn't Sam that he wanted to do this with, especially not against his will.

'Stop, please, Sam,' Castiel pleaded once again, desperate to make him understand. 'Please, I'm begging you, Sam, don't do this.'

Sam stopped his ministrations against Castiel's chest and looked him in the eye. Castiel's large blue eyes, so trusting, almost so innocent, if not for the lust trapped deep within their blue depths but for a moment, Sam couldn't miss the tears that filled the space, making them gleam in the dull light.

'Hmm... Cas,' Sam breathed heavily. 'You don't seem to be enjoying this as much as I had hoped. Talk to me. Tell me what's wrong.'

'You know what's wrong,' Castiel breathed dangerously. 'This is wrong. You must stop before it's too late. I will not be forgiving when this is finished.'

'Really?' asked Sam confidently. 'How do you think Dean will respond to that? He loves me. He wants to save me, protect me. He wouldn't let anyone hurt me, not even you.'

Castiel's face hardened as he grinded his jaw together. He knew Sam spoke truthfully. Dean would die before leaving Sam to any fate, despite anything he had done.

'Stop this!' Castiel said loudly in frustration, repeating himself for the hundredth time.

Sam sighed lovingly and ignored his pleas. He gave Castiel a shrewd smile. 'Just think... imagine if Dean were in my place right now,' said Sam, studying his reaction. Suddenly, a more knowing smile graced his lips. He leaned in close to Castiel's face. 'I know your dirty little secret, Cas.'

Castiel froze under him. His breath caught in his throat as guilt stabbed through him like a knife. Castiel had hoped that no one would find out about what he wanted. Sam had mentioned it before but Castiel hadn't admitted it but there was no hiding it now. It was out in the open.

Sam knew he hit the sweet spot and he chuckled knowingly. 'I'm sorry I cannot give you what you want, but I guess I'm gonna have to do, this time.'

Castiel swallowed hard, his mouth dry as he shivered involuntarily as he looked up at Sam.

When Sam's hand movements started again, Castiel hissed through his teeth, making Sam smile. Sam quickly felt himself become impatient and he shifted off Castiel, ripping off the rest of his clothing easily.

'Deep down, you want to experience this,' Sam whispered.

Minutes passed and Castiel said nothing. Sam took Castiel's silence as a yes and he began kissing the angel's neck while running his hand through the dark hair. Castiel's eyes closed and he couldn't help but moan as the sensations travelled through him. Sam slowly made his way up Castiel's face before finally pressing their lips together in a heated kiss. Castiel moaned in pain and pleasure since his lips were sore and tender. He eventually opened his mouth, giving Sam access to his mouth and allowing him to plunge his tongue inside.

Sam quickly removed the constricting tightness of his own clothing before thrusting his now naked body against Castiel's; causing friction that was both a torment and relief. Sam finally broke the kiss and looked down at Castiel's pale face. The pink on his cheeks had deepened and the bruises were bright and shiny. His lips pouted outwards, making Sam watch them intensely.

'Tell me what you want, Cas,' Sam whispered in a husky voice.

'No,' Castiel gasped, his voice catching in a sob. Castiel attempted to fight it again. He couldn't agree to this, no matter how good it felt and no matter how badly he wanted it. 'NO!' he shouted.

'Shh....' Sam said pressing a finger to Castiel's lips. 'This is what you've always wanted and I'm gonna give it to you. You're gonna beg me...'

A single tear fell from Castiel's eye. 'Please,' he whispered fearfully. 'I never... I don't...'

Sam chuckled. 'Relax,' he whispered tenderly. 'I'll make this feel really good.'

Before Castiel could say anymore Sam kissed him again deeply. Sam moved his hand and slipped it between them again, grasping Castiel's throbbing cock. Castiel let out a strangled cry as pleasure exploded through him. As Sam began stroking his cock's length, all of Castiel's rational thoughts went out the window.

'Oh,' Castiel moaned, caving in.

Sam smiled wickedly. 'You like this, don't you? You like me jerking you off. Such a dirty little angel. I think someone needs some more bible lessons.'

All of Castiel's self control was now gone, replaced with a desperate, clinging need. A need that had to be taken care of. Sam smiled smugly, knowing that he had finally won.

Sam slowly slid down Castiel's body, his mouth coming close to the cock in his hands. He glanced up at the angel before taking the swollen member into his mouth, sliding it deep into his throat. Castiel screamed at the unexpected but incredible sensation. He strained against his restraints and his hips thrusted wildly. Sam continued to work his member, running his tongue along it.

Castiel quickly and desperately began to sob and moaned Dean's name. Sam eyed him when he realised what Castiel was saying. He slid the angel's cock from his mouth and stroked it painfully slow as he glanced up at Castiel. He smirked again.

'I knew it,' he whispered triumphantly before pausing. 'You want some release?'

Castiel nodded frantically. Sam's teasing didn't stop. 'Huh-ah, I don't think so. Beg me and I'll give you what you need.'

Castiel shook his head violently. 'I... will... not... BEG!' he shouted in torment.

Sam growled low in his throat. 'Beg me and I will give you what you want,' said Sam fiercely.

Castiel fought within himself, to stop himself, to not say anything, to not beg for this. But deep down he knew it was a losing battle. He sobbed quietly. He caved in again.

'Please... please,' Castiel begged. 'Please, give me release, please!'

'There's a good angel,' Sam purred. He took Castiel's member back into his mouth, and took it all the way down to its base. The feeling was too much. A wave of indescribable pleasure passed through him. He cried out as he came, releasing it all into Sam's waiting and eager mouth. He sucked it down greedily. When he finished, Castiel went limp, weakened by the experience.

'Well,' said Sam, licking his lips. 'I'm guessing that felt good...'

The feelings of pleasure that Castiel had experienced quickly vanished, to be replaced with nothing but heavy guilt. His deep blue eyes filled with tears once again and they slowly trickled down his cheeks. Sam immediately reached up and gently wiped them away, shushing him quietly.

'Don't get me wrong, Cas,' said Sam slowly. 'Part of me wants to stop but the other part of me wants to finish what I've started. It's not nice to start something and not finish it.'

Sam leaned forwards and kissed Castiel passionately, allowing his own frustrations and feelings of pleasure almost boil and tip over. He grunted as he forced his tongue into Castiel's mouth and dominated. When he broke the hard kiss he pulled right back and persuaded Castiel to look at him. Sam took hold of his own leaking cock and he slowly stroked himself.

Castiel moaned involuntarily before placing his head back onto the table and exhaling sharply. Sam smiled wickedly, knowing that Castiel could no longer contain himself and Sam's own feelings were almost the same. He wanted nothing more than to touch Castiel, to make him know what it was to be human.

He reached between Castiel's parted legs and his ghosted over his entrance, making Castiel whimper and gasp in surprise. Sam placed a hand to his mouth and sucked on them, making them wet. Slowly, Sam pushed a single finger into Castiel's body. Castiel's eyes closed tightly at the initial pain.

'I'm gonna make you scream,' Sam whispered thickly.

Castiel whimpered, keeping his shut. Before long a second finger joined the first and then the third joined in, slowly working inside Castiel's body, stretching and readying him for what was to come. Suddenly, Sam pulled out all three fingers, causing Castiel to whimper but before he completely realising what was happening Sam positioned himself and thrusted his cock deep into Castiel's hole, causing the angel to scream in a mixture of pain and pleasure.

Quickly, Sam began roughly thrusting into and out of Castiel's body, hitting the single sweet spot inside of Castiel. New shocks of pleasure ran through him, causing his mind to blank and his body to react accordingly. He screamed, just as Sam had wanted and Sam smiled. He jerked his hips, moving faster, wanting to feel more of Castiel, wanting to fill him deeper. Sweat ran down his face as his thrusting turned faster and harder in order to reach the orgasm he so desperately wanted.

'Please...' Castiel begged unexpectedly.

Sam smiled calculatingly. He knew what Castiel wanted. He reached down and took hold of his now hard cock, pumping it in time with his thrusts. Castiel pulled against his restraints once more, desperately wanting to hold something, even if that something wasn't what he wanted.

It soon all became too much. Castiel lost control again and orgasmed, screaming and eventually sobbing with relief and anguish. Sam quickly followed, grunting in pleasure. Castiel opened his eyes and watched as Sam finished. Everything had now changed. Castiel's eyes darkened.

When Sam finished he quickly removed himself from Castiel's body. Castiel's darkened blue eyes watched him, wondering what his next move would be. 'Sam,' he croaked weakly.

As Sam finished dressing he turned to face Castiel one last time. He smirked when he looked at Castiel. All he saw was a falling angel. Without warning, the restraints holding Castiel down disappeared but he did not move. He wanted nothing more but his body would not do as it was told. His strength had been depleted.

'Sam,' he groaned once more.

'Thanks for everything, Cas,' said Sam cheekily. 'You are quite the angel. Give my regards to Dean when you see him.'

Sam turned and walked towards the door. He grabbed the brass knob and turned it slowly. The door creaked opened noisily and Sam took one step out before stopping and turning his head half way. But whatever he was going to say never came. He had changed his mind.

As Sam walked out he closed the door behind him, leaving Castiel alone. Castiel sobbed to himself. He felt nothing but guilt as he relaxed his body, ignoring the sudden soreness that he felt. As Castiel felt his body go limp and numb another tear left the corner of his eye and disappeared into his dark hair. He closed his eyes.

What was he to do now?
