Note: Here, have a sex scene a day early. Hopefully the second half will be up later today, but no promises.

Just a quick thing about the blog I write with this – when I say I 'review' the chapters, that doesn't mean I say how fabulously I wrote it. Actually it's more of a companion to the story – I talk about character motivations, and how it links back to the show (because in my opinion, RTD always implied this pair in his wonderfully sneaky, child-friendly way). Like did you notice how the Master echoed the Doctor last chapter?

'Because I've always had the greatest secret of all… I know you.'

Sorry. Rambling is one of my things. In any case, you might find it interesting. I try not to post spoilers, since for now this fic depends on you lot reading between the lines, but believe me when I say I don't write their lines and actions just because it seems like a good idea at the time: there is a reason behind every action between these two.

Blog post for this chapter is now up, although don't expect too much character motivation stuff up there - the motives here should be... ahem... rather obvious.

As always – thanks for all the support, and as always – please leave me a review when you read? They make me happy.

Chapter 36

The Doctor's fingers dug into the Master's chest, still pinned between them as they pushed against each other, both vying for control, both pouring their rage into the sudden, furious kiss. If the Doctor had been lucid, he would have known that fighting the Master for dominance was a battle he could never win; but those words had been the thing he'd most feared hearing since the phone call all those weeks ago, precisely because he feared the effect they would have.

Normally he would have been terrified of himself; of what he had given in to, but he was beyond that now: He'd lost control. Completely. Everything he was usually so careful to avoid; everything that he'd never wanted to let surface was out in the open, pulled out of him by the only person in the universe who could so easily have done it.

The Master dragged his fingers roughly down the Doctor's neck, leaving red marks in their wake on the otherwise pale skin. The Doctor didn't seem to notice the pain – everything but instinct and fury had slid away at the Master's words, and the only indication he made that he even felt the fingers was a twitch of his neck. He snarled and snatched at the other Timelord's lip once more, biting down on it hard. The Master growled louder and slammed his bodyweight into the Doctor, pinning him in place against the wall. On instinct the Doctor parted his legs, grabbing the other man's hair and pulling him forwards. Not that he needed to: the Master took advantage of the space and pressed himself even more furiously against the Doctor's body. The taller Timelord's teeth drew blood.

The Master jerked backwards against the insistent force of the Doctor's hand; against the clutching teeth. The Doctor tried to follow him forwards, but the Master's hand was still on his neck, holding him back. Both men were already panting, the Doctor's face still contorted in a snarl as he glared almost hungrily into the Master's face. The Master's expression was almost the perfect reflection, his eyes darting across this new, feral Doctor's face as he raised his free hand, swiping at the dark red blood impatiently. He sucked the rest away and lunged forwards once more, pressing the other Timelord back through the sheer force of the kiss.

The movement finally allowed the Doctor the freedom to move his hand, but instead of pulling it away he dragged it upwards. His fingers gripped at the Master's shirt collar, and a moment later a loud, violent ripping sound filled the small white room.

For the second time in two months, the Master's shirt lay in tatters on his chest. This time, however, neither Timelord seemed to notice or even care. The Master simply slid his fingers down from the Doctor's neck and followed his example, apparently deciding on some subconscious level that it was a much more simple way of dealing with the problem.

The Doctor growled into the other Timelord's mouth as the ripping of his shirt tugged at the back of his neck. He freed his hand from the Master's hair and tried to shake the material furiously from his shoulders, but the Master was planted firmly between his legs now, grinding against him animalistically, and the jacket and shirt simply became trapped between the Doctor and the plain panelled wall that he was pinned against. It made no difference, however: the Doctor was beyond thinking about technicalities. He let the material lie below his shoulders and snatched his head aside, jerking away from the kiss. A moment later, he was latched onto the other man's neck, teeth digging in to skin.

The Master's rhythm faltered just slightly and his head twitched to one side. A shudder ran down his back as the Doctor's teeth dragged against his neck. Another loud growl made its way past his lips, but he made no attempt to stop him. Instead he clawed his fingers down the other man's stomach and pulled at the waistband of his trousers sharply. They slid past his hips and pooled on the white floor.

If the Doctor noticed that he was now naked, he made no indication of it. His face was buried deeply in the other Timelord's neck, biting roughly at the flesh there, his long arms wrapped up around the Master's back with his fingers clutching ferociously at his shoulder blades. Apparently though, the Master finally decided enough was enough: a hand snatched upwards from the Doctor's hips and twisted tightly into his hair. He yanked him backwards, fixing him with a lust-filled glare.

"Enough." He snarled, baring his teeth in the Doctor's face, though the word was thick with a peculiar mix of rage and lust, and it seemed almost as difficult for him to force the word out as it was for the Doctor to understand it: he ignored the tight grip in his hair and jerked forwards into another animalistic kiss, taking the hand with him.

The Master didn't remove his hand, but neither did he pull him back. He crashed his lips into the Doctors', snarling into it. The Doctor dug his fingernails into the Master's back and dragged his fingers downwards over the skin. The Master growled, pulling ferociously at the Doctor's hair as the other Timelord ripped his trousers downwards. The Master shook them away thoughtlessly and pushed himself closer to the Doctor, the sudden contact of hot, bare flesh eliciting a deep moan from the taller Timelord. The Master's muscles shuddered under his skin.

The Doctor then did something that – had he been in any other state of mind – he would never have even considered. It would have sent a shiver down his back just to think about it; but the part of him that the Master had so easily awoken wasn't even capable of self-reflection, or of understanding the dizzyingly fine line that the Doctor had so carefully been treading for two months – that line between overstepping the mark, and complete submission. He clutched at the Master's shoulders for support, braced himself against the wall, and wrapped his legs around the other Timelord's waist.

The unexpected movement made the Master – as caught up in the moment as he was – pull away. His lip was still bleeding, a dark red smudge staining his bottom lip. The Doctor's, too, was bleeding – the congealed result of the gag torn open again in the sheer savagery of the kiss.

The Master's dark eyes flashed across the Doctor's face, taking in the anger and the self-loathing that was normally so deeply hidden. Even as they glared at each other, the Master's lip twitched on one side and his eyes narrowed almost appreciatively. The act lasted less than a second, and the next moment the Master had lunged forwards once more.

The Doctor reacted instinctively, as though drawn to the other Timelord's mouth by some magnetic force, but this time the Master dodged: He nudged the Doctor's head roughly aside with his own and clamped his teeth down on the other Timelord's shoulder.

The Doctor screwed his eyes shut, panting furiously between clenched teeth as the Master bit down furiously into his skin. He slid his hand from the Master's shoulder and clutched at the back of his neck, not to pull him away, but to pull him closer. The other Timelord made a subconscious noise of appreciation against the Doctor's shoulder, the vibration of it travelling across his skin.

The Master shoved his hand down between them, grabbing his own erection and massaging it impatiently, sliding his fingers over his tip until he was slick: apparently the idea of a feral, furious and strangely submissive Doctor had excited him more than enough, and while he seemed quite happy inflicting other forms of pain on the other Timelord right now, some whisper of sanity or reason or the shadow of a memory – or something else completely - held him back from that sort of pain. The Doctor growled in his ear loudly and bit at it with his snarling teeth. The Master pulled his fingers back and slammed him violently against the wall once more, almost in reply. Apparently both were now too far gone to communicate in any other way.

The Master slid his hand out from between them, brushing the back of it against the Doctor's groin as he did so. The Doctor tightened his grip around the Master's waist almost painfully hard, scratching at the back of the other Timelord's neck as he felt hands grab at his hips, hitching him up. He felt the Master's hips rock forwards underneath him; felt the shorter Timelord's teeth press even harder into his shoulder, and the next moment, the Master was pulling him downwards impatiently, forcing his way past the Doctor's shuddering muscles.
