There was a slight sudden blankness in the Doctor's mind and Jack suspected (as much as he had time for suspecting in a situation like this) that he was blocking something off. That was fine though. Jack would never want to know all of the Doctor's secrets, just as he'd never give away all of his.

Jack moved back as the Doctor pushed against him, gently moving back to switch positions and turn himself to press his back to the bed. As he moved, he felt his body start to tingle, an almost orgasmic buzz from his toes up towards his torso and he let out a hum of a moan against the Doctor's lips.

His head moved and he caught himself in a heavy breath.

"Okay, clever," Jack said, and he balled a hand into a fist in the sheets beside him.

"You know I'm making--" another moan, "--mental notes on all this, right?"
