Ianto stopped his hands in their movements as soon as it was clear that Sulu was spent, instead bringing his arms to wrap around the other man and hold him up as he realized he was starting to slump. Sulu's breathing was still coming fast and heavy, so Ianto rubbed his back gently, cradling him to his chest and supporting him there while he recovered as much as he could, given the situation.

"Christ, that was..." He waited a little to finish his thought, so that Sulu could catch his breath a little more. "Are you alright?" he asked, gently. "I mean... Straight from the pollen to the sex and then..." Well. Sulu's troubles getting off,as it were. "That was pretty rough. Just tell me that you're alright, yeah?" He ducked forward and pressed a light kiss to Sulu's shoulder in front of his face, trying not to sound too worried as he posed the questions.
