Sulu imagined that it wouldn't be too hard to get some coffee while on shift, really. There was a replicator on the bridge, for the times when it might be needed, but he couldn't imagine how bad the coffee would be compared to Ianto's brew. He smiled. "With any luck, I won't need it to get through the day shift. And then I won't have to worry about suffering through bad coffee, if I can come down and have some of yours."

He could feel Ianto sinking just slightly against him and knew that the other was starting to get sleepy. In any other position, Sulu would be telling Ianto that maybe it was time to get out, but the water was still hot enough that it was only going to help, and he was holding Ianto so that he wouldn't sink under the water. So he just continued to rub Ianto's shoulder, figuring that letting him sleep for a few minutes wouldn't be too bad.
