Sulu's hand reached up to hook across Ianto's shoulders, not quite fitting because of their height difference, but he really didn't care. He liked keeping his hands on Ianto, and if it was in relative public (even though there was basically nobody around), it was all the better. Little steps, anyway, he figured.

"I'm a pretty heavy sleeper when I'm tired," Sulu said, raising an eyebrow at Ianto in curiosity - smiling a little. "You'd better have some really persuasive ways to wake people up, if I end up sleeping through any alarms." ...And maybe he'd play at sleeping through it just to find out what they were. Ianto didn't strike him as the jump-on-the-bed sort of guy that Sulu himself was, after all - he was a little too... sly for that.
