Note:Here we go. We're getting really close to the interlude I really want to write (where this weird relationship will finally begin to make sense), in the meantime have some sexy bits.

I will try to get the next chapter up soon, but if I don't post before: have a good Christmas :)

Blog post is up. Hooray.

Chapter 37

The Master clutched possessively at the Doctor's hips, pulling him downwards roughly until he was buried completely inside him. He buried his face in the Doctor's shoulder harder, biting down on the flesh there until he drew blood; panting furiously against his skin.

The Doctor's hand slid up into the other Timelord's hair, clutching at it furiously as he felt the Master press himself inside. Despite his protesting muscles; despite the sudden discomfort he nudged roughly against the other man's bowed head, snatching at the Master's ear with his bared teeth as a low, loud groan forced its way past his lips. The Master grunted in subconscious reply to the sound of the other Timelord's voice.

The Doctor clutched his legs desperately hard around the Master's waist, jerking him forwards. The Master hadn't needed a prompt to move, but the Doctor's reaction seemed to spur him into action: He growled darkly, the vibration of it travelling through both of them, and then thrust forwards.

The Doctor let go of the Master's ear, screwing his eyes shut at the sudden impact as his neck jolted instinctively into a backwards arch. He let out a rasping breath and tugged even harder at the other Timelord's hair. As if in retaliation, the Master bit down harder on his shoulder, but the Doctor barely even flinched. He was too lost in himself; lost in the achingly familiar presence of the Master; in the feel of the other Timelord inside him. Self-control no longer had any meaning. All that seemed to matter was pouring all the long years of anger, frustration and self-loathing into this; pouring everything he'd ever hated about himself into the Master.

They fell into a furious rhythm, the Master jerking the Doctor's hips downwards against his thrusts, dragging his teeth across the other Timelord's shoulder until he latched onto the Doctor's exposed neck instead. The clutching hands were unnecessary, however: the Doctor pushed down against the Master's thrusts faultlessly, meeting the increasingly furious pace just as hard, as if on some level still vying for control, trying to set the rhythm himself.

The Master's face was twisted in concentration as he bit down on the Doctor's neck, his brow furrowed at the intensity of the pace. He was groaning gruffly, muffled against the Doctor's skin as the other man kept his fingers tight in his hair. The Doctor's free hand had slid beneath the Master's tattered shirt and around his back, grabbing at his shoulder tightly, his nails digging in with every jerk of the other Timelord's hips. His head was arched back almost painfully hard, the sinews in his neck quivering through tensing so desperately. He let loose a deep, feral moan from between his gritted teeth with every movement, matching the Master's almost perfectly as they moved roughly against each other.

The Master finally removed his hands from the Doctor's hips, leaving deep red finger marks in his skin. He leaned further forwards, crushing himself against the other Timelord's chest to keep him in place, and then raised one of his newly-freed hands to slip around the Doctor's arched back. The Doctor's skin seemed to twitch at the new area of contact, but the Master was beyond any type of mockery or vanity now. He seemed almost as subsumed by the act as the Doctor, as though he too had lost whatever self-control he had, pouring his own demons into the furious pace.

With his arm around the Doctor's back, he suddenly jerked the other Timelord's body forwards as he thrust into him. The effect it had on the Doctor was as though a lightning bolt had run down his spine: His entire body jolted, every muscle visibly shuddering under his pale, sweat-soaked skin. His head lurched forwards out of its arch and found the Master's shoulder, pressing himself into it desperately hard as a sharp, loud, deep cry tore its way up his throat and into the still, sterile air. The Master finally let go of the Doctor's neck, instead burying his forehead against the bitten skin. All movement halted for just a moment as the Master felt the other Timelord's muscles tighten around him. He bared his teeth and hissed loudly.

They resumed, the pace no longer as furious as it had been, but the movements still as rough and full of that strange mixture of lust and anger. The Master jerked the Doctor forwards with his thrusts, the other man reacting each time with another deep moan; another desperate shudder of his muscles. He was practically tearing at the Master's hair now, clutching to it as though to a cliff face. The Doctor's face had lost its sinister snarl, but had instead contorted into an almost painfully deep look of intensity: his eyes screwed tightly shut against the other Timelord's shoulder; his mouth open and his teeth bared almost wildly as he pushed back against the Master.

His whole body was now beginning to quiver furiously. His muscles clenched around the other Timelord. The Master was hissing at the sheer intensity of the moment, his breath against the Doctor's neck, but the taller man barely registered it; barely even noticed that his own voice was growing louder with each move of their hips, each jerk of the other Timelord's arm around his back. He pressed his forehead even harder into the Master's shoulder, apparently at a loss as to how else to deal with the sensations that were now racking every inch of him. He clutched his legs around the Master's waist almost painfully hard, pushed the other Timelord closer into his neck, and with one final, desperate jerk of both men's hips, the Doctor came.

He let out an almost deafening shout against the Master's shoulder, every inch of skin shuddering, flecked with sweat under the fluorescent light as he felt the space between them fill with warmth. The Master reacted to the shout; to the sensation of the Doctor's hips jerking uncontrollably against him, and barely a few seconds later he made a noise into the Doctor's neck that seemed a curious combination of a furious hiss and a moan. He snatched at the other man's hip with his free hand, pulling the Doctor down against him as he climaxed.

A moment later both of them were finally still; both of them resting their foreheads against the other man's skin, and both chests heaving desperately after the exertion of what had just happened. The Master's face, even though it was hidden in the Doctor's neck, for once seemed to relax. There was no sneer, no snarl, no mocking smile. He simply panted against the other Timelord's neck, taking his bitten lower lip into his mouth to suck away the blood.

And very slowly, as the intensity of the moment began to slip away; as the Doctor regained his breath, and the long-hidden fury and self-loathing began to slide back into his subconscious, his face began to change. Every second, he became more aware. Pains suddenly tore at every inch of his shivering body, and his stomach churned. His hearts, though already pounding inside his chest, began to flutter in fear – the kind of fear that the Master would never have been able to instil in him on his own.

He rested against the other Timelord's shoulder – their connection and the long-dormant memories that went with it offering at least a low level of comfort – and hid his face, waiting for the Master to regain his breath, and for another wave of whatever level of insanity took the other Timelord next.

He only hoped that the next one wouldn't take him with it permanently.
