Ianto watched Sulu move, watching him prepare himself, lying back and willing himself to relax as Sulu got ready. He breathed in and out once, slowly, before Sulu was pushing forward and Ianto's head was rolling to the side involuntarily as he panted to keep himself relaxed and accommodating for the other man. The simple action of Sulu pressing into him felt good, but it was the noises that the other man was making that set Ianto's blood on fire, and he had to keep his eyes clenched tight and his breath coming in short pants as he kept himself from coming right there and then to the sound of the other man's pleasure.

As Sulu pulled out, Ianto had just enough time to pull in another breath before the other man was moving again and this time, Ianto couldn't help a low keen that flowed up from his chest and out of his mouth. His hands moving to grasp onto the other man's biceps to hold on as he tried not to move too much in response, pretty sure that if he did he could end it right there and then, and he wanted to make this last, as tortuous as it was not to just go ahead and do it anyway.
