Ianto tried not to laugh at the combination of both the look that Sulu was giving him and the mumbling that he was doing. Ianto ran his hand over Sulu's hair again, biting his lip to keep from smiling at how sleepy Sulu was in that moment. He hadn't even kept him up too late, he didn't think. It was just a pretty rare occasion that Sulu was sleeping in past him, or that they both weren't waking up at roughly the same speed as each other.

"Sorry," he said, unable to keep from smiling a little at him. "I could leave you to sleep some more? I just...would need you to let me up, first." He quirked another little smile, nodding to indicate the fact that Sulu was pretty much sprawled on top of him, pinning him exactly where he was.
