The combined facts that Sulu was moving with him, that he was reacting in such a way as he was and that he was being so vocal about it were working together to drive Ianto crazy. He kind of loved this position they were in. Sure, they were sort of like this the last time, but. He hadn't really been able to do much himself, what with the situation that they had found themselves in.

And without the barrier of the condom between himself and the other man this time... Ianto threw his head back and let out a long, low moan before rocking his head forward again, breathing against Sulu's neck. Taking it slow, both because if he sped up, the pair of them probably would only last half a minute more at best, but also because... Ianto's emotions called for it, at that moment. Taking it slow; that intense, low, burning fire that he felt in the pit of his chest for the other man, hopefully being translated into his actions at that moment as he once more used his hands on Sulu's hips to work with the other man in slowly pulling back as much as he could before rocking his hips and thrusting upwards into the other man again, this time letting out a groan as he did so.
