Ianto's compliment did nothing to help Sulu tone down his smile, or his blush for that matter. He just grinned and leaned his head against Ianto's shoulder briefly before taking a longer and bigger drink from his glass. "Yeah, well." He laughed a little, "My mom always said I had a nice smile."

Then again, she also said that he only ever smiled when he was up to something. Which, he supposed, wasn't too far from the truth, because he found his free hand tracing random patterns down Ianto's chest. "I thought you liked my hands, though," he said, managing to sound as casual as he could in their situation. He was going to need a few minutes to rebound, but hey. It wasn't like they got nights off like this often.
