Sulu paused his movements for a moment as Ianto's hand gripped his knee, taking an involuntary breath at the unintentionally intimate contact. "I hope it does too," he said after a moment, taking more palmfuls of water over Ianto's unsubmerged skin. It would be a shame if this didn't end up working and Ianto remained cold and unhappy throughout it; he didn't want Ianto's discomfort to be the only thing either of them got out of this.

"And I'd appreciate it," he added, matching Ianto's tone as best he could, "Trying to be warm before you get in. It'd save us both a lot of heartache. Especially you, really. After all, you're the one who has to get used to the water now."
