In her pussy?

The Doctor's legs began to shake as he started to cum inside Clara's hot pussy.

"Oh, yes, Vance!" Clara moaned. "Fill up my pussy!"

He pushed deep inside her and held himself there while his cock pumped a stream deep into her and then he thrust in and out a few more times as he continued to cum.

Clara shook as his hot jizz filled her pussy. It was a long, hot orgasm and when he finally pulled out of her, his cum dripped out of her hot snatch. When his lengthy orgasm finally subsided, he stood and took a step back and realized that finally his hard on was softening and his urges were at least somewhat abated. Clara stood and turned to 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."
