I honestly didn't mean to leave this half finished for so long, eek!

On with the fun! Contains a personal headcanon or two, I guess. And sort of maybe references Incarnations without being a sequel. Idk. This got very out of hand.

-DW-

The Doctor tapped her foot against the floor, which reminded her she needed new boots, and started thinking about clothes... yanking her brain back on course, she looked at River, then back to the Master, a memory sparking in her mind.

"Stormcage!"

"You are not locking me in the Stormcage!"

"Noooo, don't be silly. You'd cause a riot, then escape. That guy who was in the Stormcage, the rude one who didn't like Rosa Parks" both her current companions looked absolutely bewildered "as part of his parole, he had to have a neural restricter put in! Unable to kill or seriously injure any living thing. Probably burn up if you regenerated, I've never put one in a Time Lord before, but I happen to know you rather like the shape you're wearing."

He glared, attempting to scowl while still looking a bit off-colour.

"You are not putting that thing in my brain. Or getting near my brain at all!"

The Doctor dropped down to one knee in front of him, resting her forearm on her knee for stability.

"You've always been keen to get inside my head" there was a flicker in his face as he understood her weighted implications "and you don't get many choices. You can either stay here, on the TARDIS, in River's very lovely chains for the rest of your lives. Or, you can accept the inhibitor, and do whatever you like!"

He blinked.

"You'd... let me go?"

"After a bit. Just to make sure the thing took. Like I said, never been tested on a Time Lord."

The Master shook his head, as best he could with the chains on anyway.

"No. I'll escape eventually. I always do! And besides, you couldn't kill me on Gallifrey. You won't stop me now."

Quiet until now, River cocked her head in time with cocking her gun.

"Maybe she wouldn't kill you. But I would."

He growled up at River, and it was clear he knew just how deadly serious the woman was. The Doctor was a bit distracted, because apparently she still really liked it when River was a little bit naughty. Focus, brain!

"There will be no killing on this TARDIS!"

"Just making things clear dear."

River winked, and the Doctor felt her hearts quicken. Knowing River, she probably heard it. Essentially half Time Lord (or was it half something else?), River had two hearts and better senses than any human. That, and she probably just knew the Doctor was still very much affected by River despite the new body. Her previous regeneration had loved River deeply, but he wasn't much for physicality and so the heat of attraction was less towering inferno, more slow burning coals. And the one before that had been very physically interested in River, but effectively useless at getting past the flirting stage, even with River's forwardness.

Actually, she felt very much like that one now, forcing herself to focus back on the Master.

"Fine."

"What, really?"

He slumped, visibly drained, features painted with exhaustion.

"I refuse to die being shot by the mongrel time vortex baby you married. Get this over with so I can take these infernal chains off!"

Well, first the Doctor needed to get a neural restricter. If she'd been thinking, she could have stolen one from the Stormcage, but they were in a bit of a hurry at the time. And she was busy being surprised.

"You need a lie down anyway. Come on."

River refused to leave the Master alone, insistent she was fine to watch him while the Doctor went to sort out getting the necessary inhibitor. Not that leaving the two of them alone was ideal, but she asked the TARDIS to keep an eye on them, and she was only gone for an hour. Well, an hour and a bit. A couple of hours. Six hours, tops. She had to break in to an intergalactic hospital and steal a neural restricter, and she was almost out before remembering she didn't have the instructions. After the incident with throwing the TARDIS manual in a supernova in a tantrum and then struggling to repair her machine, the Doctor wasn't taking chances and had to go back.

That was when security spotted her. There was a lot of running. Some screaming. An incident where she accidentally disturbed a Slitheen getting stitches, and the stopping to apologise almost got her caught.

Basically, by the time she got back to the TARDIS, a few hours had passed and she was slightly concerned that River and the Master would have killed each other or something equally terrible. Surprisingly, she found them sitting in relatively peaceful silence, though the tension could have been cut with a blunt spoon.

"And what sort of time do you call this?"

The Doctor felt a smile cross her face at the nostalgia - that was what River had said to her right before the time she - well, she was a he then - flew the Pandorica in to a crack through space and time to reset the universe.

"Ok, I was gone a bit longer than anticipated. There was maybe some guns and a misunderstanding with a species or two... but I got out! And I got the thing. I even brought the instruction manual, just in case. See, prepared!"

The Doctor knew pretty much how they worked, she'd just never put one in before. But she'd definitely done trickier things... probably. The real trick was going to be keeping her hands steady, as they had a tendency to fly about all over the place whenever she was excited. Which happened a lot. Her fam compared her to an oversized puppy sometimes.

"Do you know what you're doing?"

"Mostly. If I was gonna kill you, I'd let River do it. She wanted to dig a diamond out of someones brain with a sonic trowel once."

"I did?"

The Doctor winced.

"Oh. Whoops. Spoilers."

She'd forgotten about the fact they never met in the right order. Hell, the Doctor wasn't even entirely sure what point in River's timeline it was. She'd never mentioned meeting female Doctor, but then she had been very good about not divulging knowledge of future regenerations before.

"Ok, I've programmed this. I think. We'll find out when you wake up."

The Master rolled his eyes.

"If I wake up."

"Well, the test when you wake up is you get to try and kill me, so I thought you'd be happy about that."

The Master let out a short bark of a laugh. River blanched.

"Doctor! What if it goes wrong?"

"Oh. I hadn't thought that far ahead. Well... I'll figure something out while he's resting. I'm good at plans on the fly."

With her wife rolling her eyes in the background, the Doctor dosed the Master so he'd sleep through the admittedly short procedure. Holding the restricter carefully so it wouldn't try and absorb itself in to her instead, the Doctor placed it on the Master's forehead. It made a noise, hissed up at her, then seemed to disappear before her eyes. River leant over, magnificent hair brushing the Doctor's face.

"Is that it?"

"What, were you expecting scalpels and cracking open his skull?"

"Ideally, yes!"

Now the Doctor was rolling her eyes.

"I forgot how infuriatingly murderous you can be."

"Well, you can be murderously infuriating yourself. It's why we're a good match."

Was now a good time for pouting? Probably not.

"Let me know if he wakes up."

"Who are you talking to?"

"The TARDIS, obviously. Let's let him rest, that knockout lasts a couple of hours."

River looked dubious, but then something crossed her face that the Doctor was slightly concerned about. River's moods could be a little... turbulent. That was probably the work of the Silence team trying to turn her into a murdering psycopath. They couldn't totally rewire River Song, but enough damage was done that the Doctor knew her wife would always be in shades of grey when it came to good versus evil.

Then again, the Doctor herself could hardly judge.

"That's a very good idea."

And with that, River grabbed her hand, dragging the Doctor from the room, with a ding from the TARDIS to let her know the Master was being watched over.

"Where are you going? Do you even know the way around this new one?"

"No, but she likes me."

After a few more twists and turns, they ended up in what turned out to be a bedroom. It seemed the TARDIS had designed it with River in mind, the decor feeling like the perfect backdrop for someone to be seduced to their death. Not that she expected River to kill her...

"So, while you were gone, the Master... do I have to call him that?"

"That's his name. I think he'd gut you if you called him Koschei, even if you said it in Gallifreyan."

The fact River knew Old High Gallifreyan was still quite magical to the Doctor, a tongue otherwise almost completely lost. She still wasn't sure how River knew it, but assumed either the Papal Mainframe or the TARDIS gave that to her - both had the languages in their knowledge banks.

"Urgh. Fine. He kept trying to get to me, though he was so lazy about it most of the time I think it was more for show than actually intending to get under my skin. At least, until he tried to make me jealous."

"Jealous? Of what?"

River's hands came up to rest on her own hips, eyes raking down the Doctor's body.

"Well, to be blunt, he said he'd 'gotten there first' when it came to your current regeneration."

She was going to kill him. Her cheeks burned, undoubtedly giving her away even if she'd planned to try and lie. Not quite able to look at River, she focused on a particularly pretty part of teh wall.

"It's... not something I'm proud of, but that's sort of happened with most of my selves and him."

"Oh, I know. I just thought it was funny that he thought I'd be jealous. Our marriage has always been more fluid than monogamous."

Well, that much was true. River had mentioned having at least two wives, and then there were all the times she'd flirted or talked about dating, despite her love life having been eternally entwined with the Doctor ever since she'd regenerated from Mel to River.

"You know?"

"Oh, of course. I know your type, and I know how the Master has always pushed your buttons. Is it true he was a woman?"

"Yeah, that was Missy. I never... with her. My last self wasn't big on the touching."

She had to remember that River hadn't met him yet. Which makes it weirder that she knew about Missy. Time travel lifestyles got complicated.

"What about this one?"

The implications were laid on so thickly River might as well have just leapt on her. There was something so magnetic about the other woman, and honestly the Doctor wasn't sure if it was her hair or her hearts, the swirl of Time Lord DNA wrapped around her human double helix mixed with her incredible charisma.

"Well, there's only been him, but... this one likes it."

Closing the space between them, River didn't waste time. She never did. Well, except for dramatic effect sometimes, but given that she herself could be guilty of the same, the Doctor couldn't judge. River had just enough of the right DNA to smell a little like home to the Doctor, burying her face in River's neck and inhaling the scent of her wife as nimble, mischief-making fingers slid into her hair, using the grip to tip her face up. Their heights were about the same, though River's amazing hair made her look taller.

The first sweep of lips was exploring, tasting, but it was quick to become sloppy and heated. It wasn't really hard to guess what was on River's mind when she hauled the Doctor to a bedroom, but that didn't change the almost overwhelming rush of still-new feelings in her new anatomy. Tingles in places she wasn't used to. That pervasive sensation of slickness as she grew wet. The needy clench of muscles she'd not had before.

River still affected her so much, even if her body didn't - well, couldn't - respond in the same way it used to. Or would in the future, for River.

"Much as I love the coat, take it off or it might get ripped."

"You wouldn't!"

She slipped off the coat anyway, folding it and placing it down protectively before letting River near her again. River took in the braces on her shoulders, threw her head back and laughed aloud. It was a very pleasant view.

"Of all the things to make a return."

So this was almost definitely post bowtie-Doctor River.

"I can't find trousers that fit and stay up! I don't know how earth women do it."

Still laughing, River twanged her braces playfully before pushing them down off her shoulders, and already the trousers seemed to sink an inch or two on her hips, the hem of her t-shirt peeking out and making it look like she'd never tucked it in in the first place. River, on the other hand, despite some form of theft followed by chaining a Time Lord and breaking the Doctor out of the Stormcage, being chased by Judoon guards, looked perfectly put together. It was quite rude of her, really.

Except for the flush on her cheeks, blood pumped up by two hearts always quicker to display that tell-tale arousal. Feeling as though it was terribly unfair she already looked so rumpled while River looked fresh from a runway somewhere, she pushed at the snug leather jacket, gratified when it fell to the floor with a thunk! that was far too loud - pockets bigger on the inside, clearly.

"What's with the rainbow stripes, really?"

"OI! I love this t-shirt. I got it in a few different colours. The t-shirt, not the rainbow. Although I suppose rainbows do come in a few different colo-mmph!"

River silenced her with a bruising kiss, and any irritation at being cut off was soon melting away under the heat of her mouth, lips only seperating to move on to removing more clothes. Both her t-shirt and undershirt hit the floor, and River slowed down then to take in the new shape of her.

"Ohhh, you really did well out of this one."

With her shirts pulled out, her trousers had no incentive to stay up, slipping a couple more inches down her hips and threatening to leave the Doctor in nought but boots and underwear.

"Let me just get these off, theres a lot of laces!"

River didn't stand idly by, opting to continue undressing herself while the Doctor fiddled with her boots, distracted by increasing amounts of tanned skin on show but managing to undo the laces and kicking them off. Her trousers fell down completely when she stood up again, but River seemed very much approving.

The Master was rough, violent even when they'd fucked. River wasn't gentle, but it was all passion and desire that fuelled her as she pinned the Doctor down, one hand holding her wrists above her head while the other gripped tight at her hair, biting kisses on her mouth and jaw bringing out those whines and whimpers that River seemed immediately taken with from her. Little more time was wasted before River came down to explore her new curves, thumbing a pebbled nipple through her bra and smirking as the Doctor bucked and moaned under her.

"Oh, a sensitive one. How delightful!"

Gulping, the Doctor squirmed as River's hand squeezed her more firmly, palmed her through the fabric and sucked teasingly at her collarbone. Which, as it turned out, was quite sensitive. Still getting used to the wet sensation spreading between her quivering thighs, the Doctor managed to dislodge River's hand on her wrists and roll them over, discovering just then that she'd forgotten how to remove bras other than her own. Her lovely wife was only too happy to help, both discarded to some distant part of the room before they were kissing again.

River's skin was so hot, adding to the general feeling that she was on fire the whole time as she shimmied down and pressed the length of their bodies together. Hands ran down her back, squeezed at the side of her hips. kissing lazily as hands began to map the routes their eyes had already picked out. One of her hands couldn't resist River's hair, a handful of those wild curls absolutely essential to her in that moment.

Wriggling under her, River managed to wedge her thigh between the Doctors' own, and the pressure of that tight thigh muscle against her soaked cotton shorts (she hadn't stopped wearing boxers just because she'd regenerated) was enough to make her body shudder all over, to tear a needy moan from her throat. River was smug as could be, splaying her hand against the Doctors lower back and using it to encourage her to rut against River's thigh, no matter how pathetically desperate it might have made her seem. A penis seemed so... central, like it was super clear where to touch, where was sensitive.

But now everywhere felt so tender, the grind enough to have her own thighs spasming each time River tensed under her. With the Master, it hadn't been so much foreplay as him satisfying his own curiousities about her new body. River was all about the seduction, the tease, the breaking through nerves over inexperience until she had her lover trembling atop her. Those damned fingers of hers were back around swollen nipples, the visual alone of River's bare chest beneath her enough to knock the breath from her chest and the steady pressure against maddeningly sensitive spots just too much.

The shake and squeeze of her thighs as she comes is still unfamiliar, but the rush of it all is unparalleled, River's scent in her lungs and the shared thump-thump thump-thump of double heartbeats pushing her higher, dimly aware of how soaked her shorts are as she slumps, River's hands moving to hold her hips and keep her upright while the Doctor tries to catch her breath.

She realises River is giggling, and it's admittedly a small knock to her confidence at a rather vulnerable moment.

"What's so funny?"

"Oh, nothing, nothing. Just... you make the exact same sound when you come as you did before. I suppose I expected that to change, since your voice and accent have."

"Oh."

River moved, arms circling her as she rolled the Doctor back on to her back.

"Did you think I was laughing at you sweetie? Absolutely not!"

The reassurance was welcomed, as was the little pet name, but the feel of her wet shorts getting cold wasn't entirely pleasant. Somehow, she didn't expect River to mind her next request.

"I really need to take these off."

"Allow me."

River slid them down her legs happily, removing her own to "even the score" before shamelessly taking in the bared skin, kneeling between the Doctor's legs so she couldn't close them and hide, shy when it wasn't such a rush like before. It was very rare she cared whether or not a regeneration came out conventionally attractive, but it was different with River. River was bewitching and she knew it, had weaponised her natural beauty and seduction for both good and evil cause alike. The Doctor wasn't sure whether the capability to knock out her higher brain function counted as good or evil.

It was hard not to get transfixed by River's hair, honestly, but the Doctor managed to push through as she found her nerve - maybe she'd regenerated and had a whole host of new things to learn about her body, but she knew River's body already, and that was a much-needed confidence boost to her racing mind.

And, with the filthy sounds she made between breathy, lewd encouragements, River certainly knew how to refresh her memory. That spot on the side of her neck still made River clutch the sheets when the Doctor sank her teeth down, one hand coming up to grip at her hair when she sucked a bruise into golden skin. It sent shivers down her spine, the flickers of pain, the memory of rougher hands on her. Shaking off those thoughts, she focused on River, soothing her tongue over the bruise, thrilling in the ragged panting breaths of her wife.

Fuck, the woman was all curves, with those criminal hips and, in River's own words, "cleavage that could fell an ox". If River thought the Doctor had done well out of regeneration, personally, the Doctor felt like River won the regeneration lottery. And she was effectively stuck that way, having given up all her regenerations to save the Doctor. After trying to kill him. Her? Oh, it was confusing.

Her hands were smaller than she was used to, but the way River's breasts were just a little too big for her hands didn't seem like much of a hardship, and River responded to her touch in all the right ways, fingers still flexing in her hair, the little sharp tugs against her scalp turning her on even more. It's hard to decide what to do, where to go, how best to arouse and watch her wife writhe under her.

River's two hearts thundered in her chest, strong enough to feel when the Doctor pressed her lips down on the skin there, tasting the faint tang of sweat. River's taste was unique; Time Lord enough to affect parts of her humans couldn't, human enough that she couldn't mistake it for anyone else. Her scent edged slightly more to Time Lord, but only just, and it was still undeniably River.

Her instincts were a little off; old habits made her want to press between River's thighs with her hips, or hike River up on top of hers, but they didn't quite fit together in the same manner anymore. Well, at least she was very happy to learn to get past that.

When her mouth reached a swollen, straining nipple, River cursed colourfully in a language that even the TARDIS could barely translate, and the low groan of the machine herself told the Doctor she certainly didn't even want to try to, because it was utter filth, and her TARDIS probably considered herself above such things. Did everyone get such attitude from their somewhat-sentient home/vehicle?

Focus, brain! Why does this one have such scattered tracks for trains of thought?

It wasn't that River wasn't captivating, because she definitely was, it was just her brain wasn't very good at staying in one place. If there was ever a good place to stay, it was probably on River.

The rough tugging in her hair was a little distracting too, making her ache and throb and shudder. Lifting her mouth from River's breast, she looked up in case the tugs were a request for her attention.

"What's wrong?"

"Nothing at all, as you were!"

Chuckling, the Doctor resumed her 'work', hearing more multi-lingual expletives above her in between encouragement for her to go on and feeling those incredible hips bucking under her. She thrilled in River's gasps and moans as she continued down, leaving another mark just above her hip and watching goosebumps erupt across her body.

When she looked up, the naked desire in River's face was positively obscene just to look at, sending a pulse of heat through her belly as she took in the messy curls and hooded eyes, the pink flush that stains her skin from just below her collarbone all the way up to the apple of her cheeks. She brushed her lips just below River's navel, her hips tipping upward in clear invitation, shamelessly spreading her legs wider. The heady scent of River's arousal filled her senses, had her own hips pushing against the bed underneath and feeling a sense of frustration that it didn't feel like it used to.

The hand not still in her hair had already moved, River thumbing her own nipple and watching with those smouldering eyes as she waited patiently for her lover. Unable to help herself any longer, the Doctor moved in, moaning at the taste of River filling her mouth as she dragged her tongue along her wifes slit, remembering to flick over the very tip of her clit. The full-body shudder it inspired was incredibly satisfying, as were the little zaps of pain in her scalp when River's hand tightened again.

This, she could do no matter whether her form was male, female or any other possible sex. River was as responsive as ever, a constant "yes, yes, yes!" falling from her lips as the many hours dedicated by the Doctor's previous selves paid off, tongue tracing memorised paths, lips brushing the most sensitive spots to tease with the barely-there sensation. The warmth and slickness coating her face had the Doctor squeezing her own thighs together, body seeking relief from the searing heat built between the two of them.

River was so wet, she took two fingers without resistance, and while it wasn't quite the same to feel muscles clench aroundher fingers rather than her cock, it was immensely satisfying all the same, feeling River shake all over and try to push down on her fingers. The hand in her hair pulled as hips pushed down, pressing herself harder against the Doctor's tongue, River's back arching up when lips sealed around her clit and suckled gently, thighs tightening when fingers curled up and tongue traced firm circles, the pressure on all her sensitive nerves combined with the way River still played with herself.

The Doctor came up just as River started to spasm, unable to help but need to see her wife climax, and every aspect of River in the throes of an orgasm was utterly riveting, from the way her hips bucked wildly to the way her head tipped back, baring the proud lovebite on her throat as her thighs twitched and her toes curled into the sheets. Actually, the Doctor only noticed just then as she ran her eyes down her quivering body, that River's toes were painted. With TARDIS blue nail polish. Oh, she really was something else entirely.

Panting, flushed and looking the picture of debauchery, River watched with that same heated stare as the Doctor licked her fingers, savouring the musky taste of River there. She crawled up the length of River's body eventually, slumping happily next to her and feeling River run a hand down her back, tracing the bumps of her spine. If she closed her eyes, she could pick out the sound of River's hearts pounding in time with her own.

They stayed there for a little while, catching their breath, looking at each other. The Doctor still wasn't sure where in River's timeline this was, as she'd never mentioned to her other selves about a Stormcage breakout that wasn't River's own, but then River was exceptionally good about spoilers.

The TARDIS cloister bell rang at her, just once, and she remembered asking it to keep an eye on their convalescent guest.

"I should go check on the Master."

Putting on a great, reluctant pout, River lifted her hand from the Doctors skin.

"Do hurry back, I'm not done with this new body of yours yet."

Grinning and feeling the pulse of anticipation low in her belly, the Doctor nodded before something occurred to her.

"I do have one question for you about him though."

Pushing sweat damp curls off her face, River quirked one slim eyebrow.

"Yes, sweetie?"

"Why do you always have handcuffs?"

-DW-

Like I said, out of hand. It got kinda long. Turns out I ship 13/River harder than I thought. It's cool. Third chapter can happen!

(If you've never read my writing before... this happens a lot more than I care to admit)
