Ianto could feel Sulu's arousal pressing against him and grinned at the feeling of it, pleased that he'd gotten worked back up into such a state already, rolling his hips back gently to show him that, if it wasn't readily apparent from Sulu's pressing alone, Ianto was very much up for it as well.

"I would," he said, breathily, looking up at Sulu from where he was laid out underneath him. "I...want, I mean. I do. Very much so," he said, smirking in amusement at himself and the fact that he was stumbling over his words slightly. "Do you..." he started, but then started over again. "...have you ever done this before, then?" he asked. He didn't mean the sex bit, of course. He meant penetration, with another man. It was different than what things were like with women, and while Ianto trusted Sulu not to hurt him, he really would like to know whether he'd ever done it before or not.
