The utter deadpan that Ianto spoke actually made Jack chuckle. "As long as they're not stone. Stone tends to chafe a bit. Better than wood though which leaves splinters in uncomfortable places." While Ianto could manage the professional tone, everything about Jack's expression said he was already cataloguing places and was undressing Ianto with his eyes. There also was the look that said he was figuring out how much time they had between now and the Rift alarm going off.
Should be enough. Was always enough.
Even if Ianto was keeping his face neutral, Jack knew what affect he was having on Ianto. And why the hell wouldn't he be a smug bastard. "For one, I'm surprised you haven't chastised me for the amount of dirt I've left on your trousers so far." Jack licked his lips, looking up at Ianto and smiling, looking like the cat who was about to get the canary. "I'm sure you can figure out some way to be of help." Jack let a bit of heat creep into his eyes, slowly looking his lover over.
