I certainly hope so, the Doctor thought in his direction, keeping his mouth occupied with kissing along the plane of Jack's chest. He traced his tongue around one nipple. He traced out the word for 'Doctor' above Jack's heart, and only mildly worried that it was too sentimental an action.

When did he start becoming sentimental? Really? Jack did bring out the worst in him sometimes.

He traced the cold through Jack's torso, now, sliding the sensation just below his mouth as it kissed down his ribcage and hip.

He felt Jack's moan rather than heard it, and the loop of sensation went through the Doctor as strongly as if he were the one lying on the bed. Really, there was absolutely no reason they couldn't do this more often.
