Ianto's honesty made Sulu blush a little himself, smile turning into a dumb grin and hand squeezing Ianto's back. It took him a minute to compose himself enough to say anything, because it had been a while since anyone had ever said anything like that to him.

"Ianto," he finally said, sitting up to twist on the couch, so he could be facing the other man, "You're not going to mess up anything. If anything, you should be worrying about me messing it up." He leaned forward a bit, then paused and said, "But at least I know that I'm returning the favor, making you feel like that." After all, that was pretty much how Sulu had been feeling about this from the get-go.
