Luke always ends up staring at Reid's hands. It doesn't matter if he starts with looking Reid in the eye, or even that smirking mouth of his (though the smirking usually ends with Luke tackling Reid and showing him how he could better put those lips to use) but his gaze inevitably ends up with Luke following the graceful curves of Reid's shoulders, down to those adroit appendages that earn him his living.
On whole, Luke enjoys them, enjoys watching Reid do whatever he happens to be doing at the time with such dexterity, turning assembling one of his monstrosities he calls 'sandwiches' into conducting a symphony. Though sometimes it can become a little trying, he can think of one example when he was in the observation room of the OR watching Reid perform the first surgery in the new wing, and the little old couple next to him looked scandalized as Luke leaned against the glass and watched in utter fascination (and perhaps a small amount of lust) as his lover's hands held those gleaming metal instruments so perfectly.
A few weeks later, when Katie and Chris are throwing a party at their new house, Reid artfully curls his fingers around his wine glass and Luke blurts out an inane comment. Reid blinks at him.
"Play piano? I did…when I was a kid. I doubt I could find middle C now." He quirks an eyebrow. "Where did that come from?" Even after eight years of Reid, Luke is apparently still capable of blushing.
"Just curious." He shrugs, taking a sip of his soda.
When he sneaks up on Reid later, playing 'Fly Me to the Moon' on the grand piano (the extravagant housewarming gift from Lily) with so much soul that Luke can't help but join in on the chorus in a low voice close to chuckling.
"In other words, darling, kiss me…"
Reid almost jumps, and turns toward at Luke standing in the doorway smiling almost guiltily. As guilty as Reid ever looks. Luke bursts out laughing, looking delighted.
"You big phony! I bet your parents dragged you to all sorts of piano recitals when you were a kid."
Reid's still looking at him as his right hand play the opening strains of "I Wanna Sex You Up", his smile turning dirty. Which really makes it only fair when Luke bends him over the piano and shows him how to really sing.
