The Doctor let out a sigh of pleasure. This was good, this was what he wanted. Sex could never be the end-all and be-all of the Doctor's life, but being with Jack made him want to think about it just a bit more than he normally did.

"How could you miss me?" the Doctor teased with a smile. "I'm easy to find. I'm the guy with two hearts, remember?"

He reached up, tracing his fingers this time from Jack's jaw down to his sternum, the same gentle, not-quite-touching movements he gave to his thigh just a moment earlier. With his other hand, he gave Jack's hand a gentle squeeze.
