Gripping the sides of the Doctor's face to get a better angle, he parted his lips and slipped his tongue inside. The Doctor moaned in response. The Master deepened the kiss even more and reached a hand down to unbutton the Doctor's trousers. As he found his way inside the Doctor suddenly came to come to consciousness. He began to push at the Master's chest, breaking the passionate kiss.

"What are you doing?"

"I should think that would be obvious, Doctor," the Master replied as he began to fondle the Doctor in earnest.

The other Time Lord gasped in response while he pushed half heartedly at the Master's chest, "We can't do this. It's not right."

"I beg to differ. We're perfectly alone in the confines of your mind. What better place to have a little fun?"

The Doctor's eyes rolled back in his head as the Master continued to stroke him. "You…you…hurt…them," he managed to gasp out in protest.

The Master let out a harsh laugh, "Of course I hurt them. They were getting in the way."

"Of what?"

"Of this," he replied, kissing him passionately once more, "Of us."

"You tried to kill Rose because of sex," the Doctor asked incredulously.

"Not just because of sex, although that's as good a reason as any. Not that I need a good excuse to strangle that annoying little bitch."

With a mighty shove the Doctor sent the Master sprawling to the floor. Quickly fastening his trousers he rose to his feet and stood over the Master, "How dare you talk about her like that? How dare you even think about harming her."

The Master lounged nonchalantly on the mist shrouded floor, "I think, for the moment, that I hold all the cards. You are incapacitated, all of your companions have been neutralized and I…" a sly grin spread across his face, "I am in control. So I do dare, Doctor. I dare quite a lot."

The Doctor looked down at him with a hint of pity in his eyes, "And then what? Do you really expect me to follow you all over the universe watching you torture and hurt people, after you kill my companions. If you go through with it…If you harm any of them in any way, I will fight you with every ounce of my strength for as long as I live. Things will never be as they were between us again."

The Master rolled his eyes exaggeratedly, but the Doctor could see that he sat up straighter, his eyes glinting with internal machinations.

"Ok…I promise I won't kill them," he said at last.

Now it was the Doctor's turn to roll his eyes. He didn't even deign to reply, but merely turned and walked away across the white expanse.

The Master scrambled to his feet and followed, "Didn't you hear me? I said I wouldn't kill them."

"It's not what you said," the Doctor shot back over his shoulder, "It's what you didn't say. You didn't say you wouldn't torture them, or maim them, or have someone else kill them."

"We'll just drop them off somewhere then," the Master replied.

"Where?"

"Uhhh…" The Master's brain flipped through a dozen planets occupied by those that would gladly kill humans for sport, but one look at the Doctor's face told him the answer he had to give.

"Earth," he said finally.

"When?" persisted the Doctor.

An image of a t-rex flashed in the Master's mind, "I don't know when," he answered vaguely, "Whatever time we come across."

The Doctor shot him an exasperated look.

"I can't just abandon them.

"Why not?"

"Because they're my friends," the Doctor answered simply.

"We're friends too. In fact, we've been friends since we were 8 years old."

The Doctor turned to face him, "Friends? After all the years of war between us, centuries of you trying to destroy everything that I love."

The drums abated, just for a moment and the Master's face showed such longing, such need. The Doctor was sharply reminded of his old school friend, before he was changed by the insistent call of the drums.

"I'd call us friends…we were so much more once," there was a long pause as the Master warred with himself. His next words came out on a sneer as the drums took over once again, louder and more insistent than ever. "You used to love me."

The Doctor reached out to him, his long fingers brushing down the front of the tailored suit. "We're…it's…complicated."

The Master shook his head emphatically, "No," he almost yelled into the deep recesses of the Doctor's consciousness, "You are mine."

Yanking the Doctor to him and trapping his arms in a vice like grip the Master took his lips harshly, punishing, bruising his mouth as he plundered. Biting and nipping at the tender flesh he had captured the Master was vaguely aware of a shape forming at the corner of his vision…No…three shapes.

As the Doctor's female companions came fully into focus just out of his line of vision the Doctor struggled for breath, his cock hardening against his will. He felt the Master's hand grip him, felt him take him in his mouth. As the Doctor threw his head back and cried out his release the Master's eyes twinkled. The blissfully unaware Time Lord had just shown Rose the true nature of their relationship. His gutteral moans and whimpers echoed around the zero room as Martha, Donna, and Rose faded from sight.

The Doctor was his.
