Ianto's breathing really wasn't any better than Sulu's at this point. Almost every single nerve ending he had felt like it was on fire, and the worst of it was at his most sensitive part at the moment. Which was, thanks to Sulu's hand and the bucking of their hips, at least getting some attention. And it should have been enough, but it wasn't, and it was the damned pollen's fault, and god. "Dewch..." Ianto whined out, because it was pretty much a sensory overload by that point. "Dewch i ben... God, please..."

He wasn't even connecting what language he was speaking anymore as he begged for something to finish it, for it to be over. He was pretty sure that if it continued like this he was going to lose it. And that if it ended right then he might pass out or god knows what, he wasn't quite sure but just like Sulu said, come on, already.

Not really knowing what he was doing, not being really all that careful because of it because god was his mind elsewhere at that moment, Ianto did the only thing he could think of to try and end things fast. Letting go of Sulu's hips with one of his hands, he pressed a finger inside of Sulu and, not even bothering to be subtle about it, stroked it right over that bundle of nerves inside of him.
