Sulu couldn't care less on whether or not he was missing sleep at that point, turning his head to kiss Ianto back briefly before trailing licks and open-mouthed kisses along Ianto's jaw, pausing at his throat. He didn't use much force; his lips mostly rested against the skin there, feeling Ianto talk as much as he heard him. He loved that voice and that accent, and damned if he wasn't going to say so - eventually.

"I would never," he said, trying for scandalized and just sounding pleased - so pleased that he got to practically sink against Ianto and put his hands wherever he wanted. He wished he'd known this had been a possibility sooner; he would have jumped on it. "I'll have plenty of sleep. But first - I have a promise to keep, and a Welshman to keep happy." He rocked his hips again, just a little, and asked, "Any idea accomplish the latter?"
