Lust.

It was such an odd thing, The young Earl of Phantomhive mused as he caught the flash of demonic red in his butler's ruby eyes, it could control the thoughts of any beast. It could be quite the devil, if you would excuse the pun, to deal with.

"Sebastian." the young master said with a smirk. He could see the bulge in the demon's trousers despite the fact the butler was trying desperately not to draw attention to it. "Come here."

"My Lord?"

"Don't make me repeat myself."

Sebastian swallowed nervously before cautiously approaching his master.

"Sit."

The demon sat on the desk in front of his master, breathing slightly faster that usual. Ciel looked up to Sebastian's face as he pushed apart the demon's legs. He stood between Sebastian's legs and gently ran his hands up the elder's thighs. "Young. . . Master. . .what are you. . ."

"Not another word." Ciel said unbuckling Sebastian's trousers, releasing the elder male's stiff member.

Sebastian watched with large eyes as his master lowered his head and licked up his hard length. The butler hissed in pleasure, his hands clutched the desk and the young master engulfed the member into his small mouth. "Ah. . .young. . .M-master. . ."

Ciel pulled back suddenly. "I said no talking."

"My apologies." Sebastian said wanting nothing more than for his master to continue.

And continue the younger male did, using his hand to help his mouth bring Sebastian pleasure. It was when Ciel began deep-throating the elder that he really got a reaction. Sebastian obeyed and said not a word, only letting out groans of pleasure. Then, letting out a low moan of warning, the elder came, spilling his juices into his young master's mouth.

Ciel pulled away, looked up at Sebastian to make sure the elder was watching, and swallowed.

'Shit.' was all Sebastian could think.

For some reason (like we all don't know what reason THAT was), Sebastian felt a whole lot more relaxed through out the day.

However, it appeared that the young master recalled nothing of the event that took place inside his study.

'Hmm. Curious.'

Over the next few hours, Sebastian began to suspect that he had imagined the whole thing. The young master acted as he usually did, filling in paperwork and drinking tea. He made no indication that there had even been an intimate moment between the two of them. Or that he had sucked Sebastian off.

Ciel smirked into his tea.

Oh, he had been very cleaver. He was currently driving his butler up the wall. It was so easy to act as he normally did in front of Sebastian and make out like the whole 'sucking Sebastian's cock' thing had never happened. He knew Sebastian wanted him and that's what made this little game such fun.

The only problem was how hard he got whenever he thought of the lust that was clear in Sebastian's eyes.

Needless to say, Ciel wanted Sebastian too.
