In her mouth?

"Here it cums!" the Doctor moaned.

Clara got off him and backed down his body, taking his throbbing cock into her hands. It was already shooting streams of spunk, and she took it into her mouth. She swallowed everything he had to offer, amazed at the amount of cum. When he finally stopped cumming she took her mouth off his dick and smiled up at him.

"Wow," she whispered.

Clara stood and looked at him; her face was flushed partly with excitement and partly now with embarrassment. She was surprised at how much she had let go and given in, and to this stranger too. Though now that her head was clear, she began to put some things together and she thought she knew who Vance really was. She kept this revelation to herself however.

When his breathing began to return to normal, the Doctor was about to say something to Clara when the lighting in the room began to dim. Soon items were disappearing; the sink, the wall fixtures and paneling, the tub. Soon he and Clara were wet and naked in a dark empty space.

"What's happening?" Clara asked, and then she too was gone.

The Doctor began to look around and was going to launch into one of his famous rants, when his vision soon went black and he was aware no more.

He awoke in his (dry) clothes, lying on the floor of his TARDIS. He stood quickly and checked himself in the mirror. He was still in the guise of the good-looking young hunk.

"So the game is still afoot?" he asked no one in particular. "Excellent."
