Sulu's eyes closed as Ianto's hand found his hair, realizing belatedly that Ianto seemed to have figured out one of his weak spots. Not that he minded, considering how nice it felt. "Well, if you're going to use that tone on me, I guess I can't," he murmured. He had to take his hand away after a few long strokes, ducking his head to kiss Ianto's neck as he reached for the tube he'd briefly abandoned beside them.

He had a feeling Ianto wasn't going to need too much working over before he was ready, but he wasn't going to skimp on the preparation because of that. He made sure a few of his fingers were coated and leaned over to kiss Ianto's neck again, his hand going back to wrap around his erection as he shifted enough to move his prepared hand, a finger pressing almost lazily against Ianto's entrance, working him over until he could press it inside.
