I spent nearly three weeks collecting every single pairing I saw in preparation for this fanfic (I have about 101 or so now), and two nights ago whilst I was lying in bed I decided I should start working on it. I finally wrote down three pages worth of dialogue but then realised that I wouldn't be able to finish this in one go- it was intended to be an oneshot- so now it'll have to be done in chapters. Also, there is no distinct timeline to this story and I wasn't quite sure how to write it out, so bear with me please.

I do not own Full Metal Alchemist.

Mustang idly twirled in his chair slowly, his eyes closed trying to make up for the lack of sleep he had gotten in the past week. He finally opened his eyes as he heard someone clear their throat from the doorway.

"Your coffee, Sir." Roy shifted his chair closer to the desk and cleared space for the four mugs. "Thank you, Hawkeye." He thanked lethargically as the mugs were placed in front of him. He immediately picked one up and began to consume its contents. "Any particular reason you're so tired lately, Sir? I can only account for two nights ago." She said with a small smirk.

"Ah, no reason in particular." He replied after getting through the entire first mug full. "Work to finish off and such at night. Procrastination has its price."

Hawkeye only nodded and started retreating towards the door. "Oh, Hawkeye?" Mustang called before she managed to exit the room. She turned in response. "Nice ass." He smirked. She merely continued towards the door and before exiting countered "If you behave, you may see more of it later."

"Then I'll see you both later." With that, Riza left the room.

Within five minutes or so, Mustang drank two of the remaining three mugs of coffee and made a start on the little paperwork he had. There was an abrupt rapping on the door to which he gave permission for the person to enter. As the door swung inwards, Riza once again stood in the doorway. "Sir, Edward is here to see you." She reported.

"Send him in." Mustang commanded and picked up the last mug of coffee. "And can you get me more coffee please?" He requested, smiling amiably. Riza sighed and collected the mugs on his desk. "I'll get them as soon as I've finished the paper I'd started, Sir. How much?"

"As much as you can carry." Riza nodded and walked out of the door just before Edward entered.

"Hello, Colonel." Ed sighed lethargically as he threw himself haphazardly onto one of the sofas. Mustang took another swig of his coffee then developed a wry smirk. "You seemed to have more energy last night, Fullmetal." He chaffed.

"Bastard."

"That's not what you were calling me last night; 'My God', was it?" Mustang retorted, causing Ed to blush. Ed was about to make a comeback but was distracted as Al came into the room with a kitten. "Hello, Brother!" Al greeted excitedly.

"Al! What have I told you about cats? You can't go picking up random strays!" Ed chastised.

"But brother, he-"

"No, Al!"

The argument continued for another minute until Mustang jumped up from where he had been sitting, drinking his coffee and watching the argument. He quickly dashed out of the room; muttering something about 'coffee being a diuretic' and such. Ed and Al only continued their argument until Ed made a temporary solution. "Fine, you can keep the cat, for today only though!" Hadn't Al been a suit of armour at the time, he would have been beaming. "Thank you so much, Brother! I'll make up for it; you'll see."

"Is that a promise?"

"Promise!" Ed grinned at thoughts of how Al would make it up to him but was brought back to reality by the meowing of the kitten. "Anyway, I have to wait for Mustang to return, no point in you wasting your time in here too."

"Okay, Brother. I'll see you later." Al waved to his brother with his free hand and skipped through the door.
