"No no no Dean , this piece can't go there ." Castiel scolded the man , taking the piece from his hand and placing it on it's earlier spot . "Think ! Remember what I told you , try to anticipate the opponent's moves ."

Dean snorted , his mind completely confused from the amount of information he received throughout the game . Pawn , Knight , Bishop , Rook , King and Queen . Should seem pretty easy , right ?! Except Dean felt like Cas was stuffing a whole manual inside his brain . You couldn't move the pawns too far , the knights moved in the form of an L , protect the queen , don't use that , don't move this , anticipate here , think there , move now , stop and do it again … Ugh ! Dean wanted to throw the pieces around the room . Or burn them and stomp on the ashes . Dean fancied the latter .

"You're not touching my chess board . Now play . And try to do it right this time . You couldn't make a single smart choice from the beginning ." Castiel said , his eyes on the board . An impressive stack of white chess pieces stood by his side , trophies from a war that he knew he was going to win . Dean only had a pathetic pawn by his side . He was failing miserably , outnumbered and outmatched . But at least he took one piece from Castiel . Aside from his inner shame stood a small glimmer of pride . Maybe one day he could beat Castiel . Maybe …

But not today . He took the Bishop Castiel moved for him and took down another pawn .

Castiel's eyebrows rose in amusement . "You really are a lost cause ." He smiled . Castiel did that the whole evening . Dean entertained him . He appreciated the effort he saw on his face while he tried to comprehend the complicated rules of chess . Dean tried , and for a first time it was really impressive .

Maybe with a couple more chess sessions Dean could improve his ability . Castiel saw that Dean tried his best . Castiel challenged him with something that a normal person would not be able to go through . And Dean fought . Unexpected , but satisfying .

Despite his concentration on the game , Dean yawned . He rubbed his eyes with the back of his palm and tried to think about strategies . He really wanted to beat Castiel at chess .

"Dean , tired ?" Castiel questioned , his gaze now fixed on the human's face . Strong , determined green eyes met his . "We can postpone the game until you are ready to play again . It's late . You need your rest ." Castiel was right in his suggestion . He , as a demon , didn't need sleep , but Dean did . And he needed Dean to be healthy , not ill because of his own foolishness .

Dean nodded . he picked up his white King from the chess table . "Why did you do this ?" he asked , gesturing to his chess piece .

Castiel's lips twitched in amusement . He knew that at one moment Dean would ask him . "Because I enjoy your company Dean ." Castiel said , as if he stating something obvious .

It was true , Castiel did enjoy Dean's presence and attitude . He bought him two years ago . A long time for a human slave to be in the presence of a demon . Most got corrupted by the demon's aura , twisting and turning dark . Evil . That got them killed . Dean didn't change . He kept fighting Castiel , never bowing down to him . The demon got the feeling that Dean probably didn't know the extent of his powers or what he could do . Because Castiel wasn't an ordinary demon . The right hand of Lucifer , with many privileges that others would do anything for .

When Lucifer fell from Heaven , betrayed by his kin , Castiel stood by his side , along with others . Together , they built Hell . Together they created a strong empire , one that could rival Heaven . They were strong , fallen warriors working to reclaim their rightful place .

And Dean didn't know a single thing about him . An idea bloomed inside Cas's mind . He rose from his seat , moving casually towards his desk . He rummaged through the drawers for a few seconds until he found what he was looking for . An old looking , leather bound book . It was very precious to Castiel , mostly because he wrote a big part of it . Hell , who was he fooling , he wrote the whole book , only receiving a minimal amount of help from the other fallen angels . They gave him numbers , coordinates , dates and places to make this book a great fountain of information .

He heard Dean rise from his chair and place the chess pieces back to their place . This was Castiel's usual habit , to rearrange the chess table . He turned , book in hand , and walked back to the table . He helped Dean put the pieces back , their fingers brushing a few times as they reached for the same chess piece . Castiel would smirk and continue his task while Dean stiffened for a second or two before continuing .

After they were done , Dean straightened his back and took a step away from the table . His gaze dropped to the book in Castiel's hand . He was curious . Why did Castiel bring this book ? Maybe he wanted to read it ? But then , why would he flaunt it in front of him ? Dean knew from experience that Castiel was reserved with everything that involved research , books and information .

Castiel raised his hand, offering the book to Dean . "Here , read it . I guarantee you'll be fascinated ." he said , a smug look on his face .

Dean gingerly took the book from Castiel , careful not to drop it . It looked old , powerful , filled with secrets and immense knowledge . Dean would lie if he said he wasn't curious about what was inside . "Thank you ." he replied quickly , remembering his manners , something that he didn't seem to care for a long time . Now it seemed mandatory .

"No need . " Castiel said . Dean yawned again ."It is rather late Mr. Winchester , go to bed . Good night ." he said . Dean opened the door to the room . He hesitated . Turning around , he was faced with an impatient demon who wanted him out . "Why did you call me Mr. Winchester ?" Dean asked . Surely there was no need for such formalities . he was a slave , not a freaking landlord .

Castiel smiled , again amused by Dean's transparency and need for information ."Because I can and because I want to . Now go to bed ."

He ushered the other male out . This time de didn't close the door in Dean's face . He watched the human walk away , towards his room .

The one thing that Dean didn't saw on his way to the bedroom was Castiel lingering gaze on his arse .
