Ianto was starting to notice that something was wrong. It took him much longer than it should have, to make the connection that they weren't doing this of their own accord. He'd experienced aphrodisiac's before. Hell, Jack's pheromones were pretty much really mild aphrodisiacs themselves, plus they had that cologne... But he'd never felt this overcome by anything, not without spraying that cologne, not without both parties willing. Not only was there something wrong with the fact that they were being overcome by whatever this was, though...

Something was wrong with Sulu, Ianto thought, as he arched against the other man's pressing his hips against his own. Something was wrong. He sounded... He sounded distressed. Not good. Really, really not good. Ianto struggled to get his head about him, struggled to concentrate and pull back and open his eyes, and god. It was so much harder than he had ever anticipated, but he did it. "Sulu," he said, his eyes wide, his pupils dilated slightly, "what... What's..." Almost against his will, he ground against the other man again, hips pressing into hips as he waded through the fog in his mind, trying to focus.
