Arthur was always told what he could and couldn't have, sure he would get it anyway but he still was given rules to break, so to him Merlin was no different.

The first time he saw Merlin he couldn't careless about the man and his neglecation to know his place infuriated him to the point of him wanting to show him how he should act, how he should be scared and know to let the prince do whatever he wanted. But that fight, someone trying to show him what he couldn't do first started this need off.

Each time Merlin told him that he was a "Prat" the need flared up and he never felt and he wanted nothing more than to quench it and fast but ,like everything in the princes life, his father noticed, saw the longing looks at that creatures milky white neck and the raven hair, the way his eyes linger on the beasts hips more than they should, to him Merlin couldn't be human..no that is impossible...merlin is a creature sent from Heaven hell to taunt him, show him the reason why he should break the one rule he has yet to break, God his legs...his neck...God even his ears are teasing him and how he cant have Merlin was frustrating

"Arthur, you cannot persuade this fantasy with your man-servant" How did Father know what he wanted to do both amazed and infuriated me. 'How can he tell me what I can do, its a little late to start play father.' "Father I do not know what you are on about" 'Perhaps if you want this conversation you should of started a long time ago instead of teacher after teacher'
"Arthur, you are heir to Camelot, how would the people feel if you have this with your servant? The other kings would take note and use him against you and Camelot will fall" ' Of course Camelot cause I always the reason that Camelot will fall.'

"Arthur.....oh god....Arthur....faster......harder" Merlin's broken moans echo around the armor room were Arthur couldn't take anymore, this control broke and he took Merlin's hands off the sword and...Arthur....Arthur ....ARTHUR!?!

The clatter of pots arose Arthur out of his daydream and meet the scared face of Merlin
