The Doctor knew that he should push his human self away, but he couldn't make himself do it. He wanted this too much; he couldn't say exactly why, but it was heady in a way that nothing else had ever been. He felt as if he was drowning, sinking into a sensation that he never wanted to be released from.

Were his own lips this soft? he asked himself, almost whimpering when his human self pulled away from their heated kiss and raised his head. One hand stroked through the Doctor's hair, his other hand still inside the Time Lord's pants. The Doctor moaned aloud as those long, slender fingers stroked his erection, his hips jerking up against that warm hand.

"I think you want me just as much as I want you," his human side whispered, lowering his head again to nip at the Doctor's earlobe. "There's no sense in beating around the bush, is there? There's no one here to know -- and neither one of us is going to tell. This may be --" Here, he stopped, swallowing hard and blinking rapidly.

"This may be what?" the Doctor queried, his voice hoarse and ragged with desire. It was hard enough to wrap his brain around the fact that this was actually happening; he couldn't be expected to keep up some pretense of coherent conversation.

"This may be our only chance to be together," his human self said softly, an expression of infinite sadness spreading over his features. "I don't know what the future holds in store for either of us -- but I have the dreadful feeling that we aren't meant for each other. Not in this realm, or in any other."

The Doctor's stomach clenched; he hadn't thought of that. He'd been so caught up in the heat of the moment that he hadn't thought of what the future might bring to each of them. Of course he couldn't have any kind of relationship with his human counterpart; it just wasn't possible. He couldn't take him as a companion, both of them travelling out amongst the stars.

And why not? a little voice demanded belligerently in the back of his mind. What was there to stop him? Was he only worried about how others would see the situation? He didn't give a hang what other people thought of him; he never had. Well, that wasn't necessarily true, but he didn't want to think about that now.

No. It couldn't be done -- and his human self seemed to know that. Still, that was something they didn't need to wrestle with at the moment; right now, the only thing the Doctor wanted to focus on was the delicious warmth of the hand between his legs, the sensation that was starting to spread through his limbs, over his entire body.

"Whatever you want to do -- do it," he whispered, arching his back and tightening his arms around his human self's neck. "But for fuck's sake, don't stop touching me. I think I'm going to explode if you don't keep on with that."

"Your wish is my command." His eyes widened as his human side flashed him a cheeky grin before lowering his head, his hands pushing the fabric of the Doctor's trousers down his thighs, that soft, warm mouth moving between his legs. He cried out when that exquisite warmth surrounded his cock, his fingers tangling in the human Doctor's hair.

Another soft moan left his lips when that mouth moved off his cock after only a few moments; he wanted to push the human Doctor's head back down, but he refrained, wondering just what his other side had in mind. He found out quickly when he was turned onto his stomach, his thighs pushed apart, his ass lifted into the air.

Warm breath on his bare thighs, gentle fingers spreading his cheeks. Then a soft, warm tongue licking down the cleft of his ass, circling his entrance before pushing inside him, making him moan and writhe under the other man's ministrations.

The Doctor buried his face in the pillow, his fingers clutching the tumbled sheets of his bed. This definitely wasn't something he'd expected, but he wasn't going to turn it down -- not when his desires seemed to match his human counterpart's so perfectly. He pushed the thought of any consequences to the back of his mind, refusing to think about them for the time being.

What could possibly happen? he asked himself, moaning again as that warm, wet tongue plunged inside him again. No one was going to know about this. He was fairly sure that neither of them would talk about it; he himself was too cautious about what his friends would think, and he was nearly positive that his human self would feel the same way.

After all, he reasoned, they were literally the same person, so they would probably have the same attitudes and views on this situation. And if they didn't .... well, he would cross that bridge when he came to it. But now wasn't the time to think about such things.

He could feel his trousers being pushed down his legs, his human side pulling them off and sliding his hands under the thin fabric of his shirt. The Doctor lifted his arms, wishing that it were possible to pull his shirt off -- but given what he was wearing, that wasn't going to happen. He'd have to turn over to be undressed, something that he definitely didn't want to do.

He was almost surprised to hear himself whimper when that deliciously warm tongue drew out of him; he didn't want the sensations taking over his body to stop, didn't want to come crashing back down to the ground from the dizzy heights he was being taken to. He almost cried out when his human self sat up, those hands turning him over onto his back.

The human Doctor leaned down, his hands starting to unbutton the Doctor's shirt, pausing for a moment before clutching the fabric in his fists and ripping at it. The Doctor gasped, eyes widening as his shirt came away from his body in shreds, buttons flying in all directions.

His human self looked down at him from where he straddled the Doctor's thighs, placing his palms on the Time Lord's chest and rotating them over the Gallifreyan's sensitive skin. The Doctor couldn't keep himself from moaning again, his eyes fluttering closed. Nothing had ever felt this good; at least, nothing that he could remember.

But of course, his human self would know exactly how to pleasure him, he reminded himself; he would know everything about his likes and dislikes, know every sensitive, tender spot on his body. He'd know exactly how to touch, how to kiss, how to fuck. This would be the ultimate pleasure; being made love to by someone who knew everything about him.

He couldn't keep himself from sighing with pleasure as the other Doctor stretched out on top of him, their bodies molding against each other. Those arms slipped around his waist, those lips seeking his. The Doctor's lips parted under that insistent kiss, his own arms raising to wrap around the other man's neck and pull him down.

"This can't be wrong," his human self whispered to him, soft lips brushing against the sensitive shell of his ear. "Nothing that feels this good can possibly be wrong. It can't be wrong to be a part of someone like this. It can't." That voice was almost pleading, begging him to agree with the words.

How could he say no to that? "No, it can't," he whispered, giving in to the inevitability of what was happening. He didn't care if it was wrong. He didn't care what anyone might think. This was his, his alone; his and the man on top of him, who was a part of him, more than anyone else could ever hope to be.

His hips arched upwards, another soft cry leaving his lips when the other man's cock slipped between his thighs, rubbing against his entrance. He spread his legs, feeling more wanton than he ever had in all his many lives, wanting nothing more than to be filled and taken by this man who was him, and yet wasn't at the same time.

The Doctor reached up to clutch at his other self's shoulders, seeming to startle the other man; he paused in his movements, looking down at the Doctor with wide eyes. The Time Lord's voice was almost a growl when he spoke, his words coming out in a rush.

"If you're going to take me, then do it. I can't stand this teasing." He almost couldn't believe that he was saying this; it wasn't that he didn't enjoy foreplay, but enough was enough. He needed this, needed it more than he'd ever needed anything in his life. He would spontaneously combust if this man didn't take him -- now.

The other Doctor smiled down at him, leaning over and reaching for the small table beside the bed. The Doctor knew what he was looking for, but he was surprised that his other half would know that he always kept a small tube of lube there. Why should he be surprised? he scolded himself belatedly. This man was him, for all intents and purposes.

How could he have forgotten that? For a few seconds, the nagging worry of what people might think if they knew that he'd had a sexual relationship with someone who was essentially himself made him want to break away from their embrace, push the other Doctor away and get his clothes back on as quickly as he could.

But he didn't. He couldn't have forced himself to move away, even if his limbs had possessed the strength to do so. Instead, he propped himself up on his elbows, watching the other man as he coated his fingers with lubricant, then leaned over the Doctor again.

Their eyes met, but no words passed between them. They didn't need words; it was as though each of them knew exactly what the other was thinking. The human Doctor's hand moved between the Time Lord's legs, fingers first stroking over his entrance, then pushing inside him, making the Gallifreyan squeeze his eyes closed and moan softly, his head falling back against the pillows.

Those fingers felt amazing, moving in and out of his body, probing deep, scissoring and stretching him. The thought flashed across his mind that he wanted to be taken from behind; hardly anyone had done that with him before, and it was something he enjoyed more than he'd ever admitted to any of his former lovers.

The human Doctor seemed to know exactly what he wanted, without him having to put it into words. Without a word, he drew his fingers out of the Doctor, turning him over onto his stomach and spreading his legs, settling between them. Within seconds, those fingers were back inside him, pressing against his prostate and drawing a prolonged moan from his throat.

The Doctor stretched out under his lover, closing his eyes and letting himself sink into the sensations taking over his body. He gasped when those fingers pushed deeper inside him, and again when his ass was lifted into the air; he could feel warm breath on his thighs, that wet tongue curling around his balls.

He was going to go mad if this kept up. He couldn't stand it any longer; he needed more than his human counterpart was giving him. His voice was husky and guttural when he spoke, the words formed with difficulty; he could barely push them out of his throat. His voice sounded alien, as though it wasn't a part of him.

"I need you," he growled, the words sounding garbled and indistinct even to his own ears. His voice gave out; he couldn't have formed any other words if he'd had to. All he could do was feel, his body poised on the edge of a chasm that he was more than willing to let himself fall into if he was pushed off the precipice.

"Then you'll have me," his own voice murmured into his ear, that breath hot on his skin. His body tensed, waiting, those hands trailing down his sides, an exquisite torture that he didn't want to stop. The anticipation stretched taut, almost to the breaking point; the Doctor held his breath, waiting for whatever his human self chose to do next.
