A/N: We'll get back to Lucy in a bit. But for now have some tensimm smut. I know you've been waiting for it ;D

.

There was safety in the half darkness of the bedroom. Half concealed secrets and half revealed truths. And all of them could comfortably stay in eternal twilight.

And who needs light when you have a mouth and a tongue to explore? The Master held the Doctor down with one hand, preventing him from moving too much while he made a mental map of that unfamiliar body of his. He took a note of the soft whine when he let his tongue glide over a nipple and remembered there was no reaction at all when he did the same near the belly button. There were shapes and forms to discover, the lean muscles in the Doctor's too long legs and the rough bones in those nimble fingers.

"Master." That made him stop and the distraction brought his awareness back to his own groin and the strain against his pants. "Take that damn clothes off." It wasn't a command. There was a soft hint of amusement in it. And yes, the Master was fully dressed still, whilst the Doctor lay before him, bare and very obviously not controlling his body reactions anymore.

It didn't matter much. They were half hidden and one naked and one clothed still made another half. So it matched.

"Make me." This was a command.

Only then did he remove the hand from the Doctor's chest and sat on his heels, patiently waiting. Well, as patient as one could be in his state. He recalled how there had not been the slightest hesitation when he had suggested moving somewhere quiet. He throbbed when the image from before shot into his mind, of the other man opening the door to his own bedroom, cluttered and dim, allowing the Master only a single step inside before he tugged at him, before his hands were under his waistcoat once more as if they had never left, of how tentative he had lowered his head to steal a new kiss, sweet and careful and still demanding in a way no one else would ever manage. Or even dare.

And now those hands were back, opening buttons and pushing cloth aside. The Master watched, his nostrils flared. The Doctor took his time undressing him and there was joy on his face while doing so. He was unwrapping a present he had wished for, but had been denied for too long.

"I didn't think you'd actually let me," said the Doctor when he helped get rid of the Master's shirt. "Touch you, that is."

There was no need for them to do any of this. It was pure indulgence.

"Why? It was fun the first time." Even though his head had been foggy and the wooden ship had creaked too loud.

"Thought it was just… a drunk thing, you know? And just because I said… It doesn't mean… I don't…"

"Shut up." The Master smiled fondly. "I've been having too many fantasies about you."

The Master gladly slipped from the bed to get rid of his pants and shorts, finally free from the too tight confines. In the half light he could swear the Doctor's irises vanished completely behind black. Even the rise and fall of his chest had quickened. Control be damned.

"'bout… me?"

"Mhm…"

There wasn't curiosity any longer. Now those black eyes filled with nothing but hunger, desire. The Master hadn't been the only one to fantasise, as it seemed. And he wondered if the other one had been as deterred about it as himself.

There had been a point in all of his centuries when the Master had found sex to be nothing but disgusting. Primitive and so far below him that the mere thought caused him discomfort. He had seen what many species did to one another just because they had no control over their urges. And for the longest time it had been the only thing he had seen.

The Doctor leaned over and took the Master's wrists, dragging him back onto the bed with a half smile. The Master followed the tug and half knelt there, watching the Doctor's expression. A look as if he had never seen anything as fascinating as him. And when his lips trailed warm kisses down the Master's chest, he remembered when he had started to reconsider his opinion.

No, he had simply rediscovered it. There was nothing like the sensation of skin on skin, even without any mental contact. He allowed the Doctor to kiss his way upwards to his neck, warm and soft and so alive. He shivered as the tongue found his collarbone and knew when he had first felt sensations like these. Lips finding lips, tongues dancing. They had just been playing, exploring, in secret and hidden from judging eyes. A sigh escaped him, almost a groan, when a warm hand caressed his dick, not quite taking it, more a tease.

When had the Doctor ever gained such confidence? So shy and uncertain, then. Curious and even a little bold, now. The Master got lost in it and couldn't mind. He didn't struggle when the Doctor pressed a hand against his chest to make them both lay down. The freckled face above him, half hidden, the naked body atop him, swallowed by artificial night.

But he didn't need to see.

He remembered red sun rays peeking in through gaps in wooden boards. The creaking of an old shed, a hiding place. They didn't need to hide now and the Master grabbed the Doctor's hips to drag him down and grind against him. The first moment let them both groan and almost still, the sensation of centuries without touching each other now collapsing.

It was almost too much. He needed to take the Doctor's face between both hands and kiss those stupid lips again. He needed to feel as much skin as possible and all of the fantasies he ever had got vaporised into thin air. He wanted to mark the Doctor, he wanted to defile him, he wanted to claim him and make him scream and bleed and sweat. Instead he pressed him closer, dug his fingers into the burning skin and rocked his own dick against the Doctor's, completely unable to stop. Not now, not when he finally had him, not when he was able to make him stay, to not run, to just be his.

It was primal and a little feral too. And the Master didn't care at all. Couldn't. It was red grass and creaking wood and the scent of autumn. It was the Doctor's laboured breaths and his own racing hearts and it was the flames that burned in both of them.

The Doctor groaned and pressed his lips against the Master's neck, rasping out his name, shuddering, so close, so close. And the Master pressed against him, slowed the rhythm to make each movement more intense, more precise, more, more, more, more.

He couldn't stop the groan when he came hard and sudden and shuddered, still moving, unwilling to stop. Too much, not enough. And the Doctor pressed his lips on his once again to stifle his noises when his own orgasm hit soon after. Their minds bristled, barriers crackling. The Master held tight, focusing on the pulsing between their bodies to ground himself, to not allow him to slip and the strain let him groan once more, gasping for air. The danger was thrilling, the balance on this edge would have made him hard again if it weren't for a last hint of willpower.

"You're beautiful, you know that?"

Every sinew in his body screamed, with pleasure, with heat, with the desire to kiss the Doctor and to wrap his hands around his throat. This idiot.

"Nothing about me is," he gasped.

"You just can't see it." Those warm lips ended on his neck again and the Master couldn't help but raise his head to give the Doctor access to his throat, only thinking, bite me, bite me, bite me, bite me. "So much fire." Muffled words. "So much blood." Hot hands wandering lower. "So much smoke." Control was no option any longer. "And screams." Warm fingers wrapping around him, hard and throbbing before he could so much as consider preventing it. "And chaos." The precision of the Doctor's hands, the soft tone of his voice, the praise and admiration, all those things had the Master near the edge again in no time. "So much, so much." Drowning in those sensations was so easy. "You are so much, Master."

He came again with a gasp, clutching the bed sheets with both fists, helplessly bucking upwards into the Doctor's hand. The world went black for many seconds, drowned in heat and sensation and soft words until a cold shiver brought him back to his senses. The Doctor rolled down from him, a hand sneaking its way back above his chest, drawing small circles.

And for a moment the Master thought that now there were no halfs anymore. Only one whole. But he didn't linger on the thought.

"You really think that, don't you?" he whispered. "What you said."

"'cause."

"Idiot."

The Doctor chuckled, not objecting. There was no way he didn't know how stupid it was to try and see any good in the Master. Or something beautiful. He had made sure to erase all of it, to squish and rip and tear and suppress all those things. You get nowhere by always caring too much about others. That he had learned quickly. No… not quickly.

The Doctor's soft breathing against his shoulder distracted him. From his thoughts, from being angry at the whole universe, from the slight bitter taste on his tongue from thinking about how much control he had willingly allowed the Doctor to assert over him just moments ago.

"What are you thinking?" A little muffled and by far too content.

The Master huffed. "That I could kill you right now and you wouldn't even move."

"Not true." The Doctor chuckled, then raised himself on an elbow. "Do you regret it?" He pointed between them. "This. Us?"

"There is no us." The Master scowled.

"Right now. There can be. You accepted my confession just like that and I didn't think you would and now we even-"

"Stop babbling or I'll leave."

The Doctor grinned widely. "No, you won't."

Oh this stupid, stupid… The expression reminded the Master too much of the boy the Doctor used to be, so many lifetimes ago, when their world had still been glowing orange and they had not known misery like they did now. And the Master's hearts did a painful jump at the sight.

"We can never return to an us. It's gone. It's been gone forever."

"Yeah."

The Master couldn't help it. He took the other man's face between his hands and kissed his dumb lips that were too soft and too delicious.

"We can be something, though," the Doctor breathed against his mouth. "Just something."

"Aren't we already? Am I not your dearest enemy?" A glint in his eyes. A smirk.

"We can be that and something else too."

"Mhm…" The Master hummed amused and maybe, maybe also a little hopeful. "Yeah. I'd like that."

It was better than being nothing. It was better than the emptiness that had him in its grip since days. Something new. A beginning. A promise, not for anything, but for something. The Master didn't trust it. Not even a little.

For now, though, it was enough.
