Ianto moaned slightly into the kiss. Just because he needed recovery time before he could become actually physically aroused again didn't mean that Sulu wasn't having any effect on him at all. He always had liked to know when he was doing a good job, and now he had a clear-headedness that he usually didn't get when they were up to things like this. Granted, the circumstances were less than ideal, especially for Sulu. Ianto could only hope that he could bring him off before Sulu started to get too tired of it all. God only knew how exhausting it must be, to not be able to get there.

Ianto kissed him back, deeply, tilting his head to get the right angle, before biting at Sulu's lower lip, gently. He kept his hand going slowly, steadily on Sulu's arousal, and he ran his finger over that spot as well, gently at first, and then pressing firmer. "Good," he said, against Sulu's lips. He wanted this to be good for the other man, and over-stimulating him definitely would not be the way to go about it.
