As Sulu rolled his head back, Ianto shifted to lay an open mouthed kiss across the other man's throat, feeling the vibration of air through the other man's windpipe as he panted underneath his touch. As Sulu's palm pressed against his arousal, he needed to break that off as well, groaning and pressing his face into the crook of the other man's shoulder, his breath catching in his throat slightly as he did so. After a moment of steeling himself for that he pressed into Sulu's hand, pressing Sulu's hand against his other hand and effectively, Sulu's erection too, which was an odd sensation and probably shouldn't have felt as good as it did but it was great and yet...

Ianto needed to move. He needed more than they were getting and this was great but the leverage was all wrong and he needed. He needed more. So in a split second decision, he slipped both of his arms around Sulu's torso, wrapping his arms around his chest, and sat up with him, effectively pulling Sulu into his lap. Ah, yes, that was better.
