A/N. Thank you! Warning: partial non-con. This is the reason why the rating goes up. Not the original reason why it should have. Not yet. :( Let's keep it nice and slow for now, yeah?

Previously...

Rose locked her eyes to his. But if it was a panicked 'run! or something entirely different… he honestly couldn't care less. Not when his proclaimed sweetheart was so impossibly close to him…

Black Light

So much more than you could ever give

Five months ago

Rose's mind was warning her against staying there for another minute… But she's had the Doctor with her. As long as they were together, nothing could have gone wrong.

Their proximity has suddenly hit her. It was nothing unusual for them… However, never before had her own senses been twisting within her so. She must have been feverish. "Doctor."

"Rose." His voice sounded wrong. She looked at him and would have backed away, had the Time Lord's embrace not kept her locked to him.

"Are you… are you okay?" She managed, hoping beyond hope he was at least sensible enough not to attempt something unacceptable there and then.

"Oh, yes," he breathed. "Has anyone told you just how attractive you are, Rose?"

The companion could see he was fighting the effect of whatever it was the room was filled with. She sighed, shuddering at the possibilities prolonged stay in that place might fill the Doctor's mind with. Not only that – Rose could feel the most dreadful part of the process - she was slowly getting affected herself. All of a sudden, the dangers began to seem more like a pleasant addition to this adventure.

"You just have," Rose assured him. "Although 'beautiful' would have sufficed," she muttered.

"Beautiful, charming, alluring… it all goes without saying, Rose."

She inhaled, fighting the wish to close the remaining barely-existent distance between them. It was becoming harder by the second. The remnants of her reason still unaffected by the unwished-for aphrodisiac suggested her one more way to postpone the inevitable. Even if this felt nowhere as unwelcome as before. "Talk to me. Tell me beautiful things. Tell me anything, just- keep talking. Please, Doctor…"

"Does the sound of my voice please you?" He breathed, still keeping from crossing the invisible Doctor-companion border so engraved in their subconscious not even some sort of an alien aphrodisiac was going to change that.

"Yes. Yes, it does," Rose whispered. "Very… much." Neither she nor the Doctor paid any mind to the people watching them curiously. They were both too involved in keeping the uninvited, boundaries-crashing desire away. The effort was excruciating.

"Let's get out… of this place?" She managed, almost physically feeling her reason slipping away.

"No. Not yet, Rose," the Doctor stopped her, able to fight the aphrodisiac well enough when it meant Rose's self-conscious decisions. Particularly ones so important for them both. "We should wait."

"Hm?"

The Doctor spoke in a tone no-one could ignore. "Mind granting us some pleasant, romantic environment, instead of keeping us in this hole of a place?"

"I'm afraid this isn't enough," the apparent leader of the company noted. "We should double the dosage."

"The blonde is human," someone else grimaced with distaste. "It's going to be too much for her. We shouldn't-"

"Pray, how many humans have you met in your pitiful simple life to know this, Subject-3081?"

"It's common knowledge."

"Not when her lover's a Time Lord," the one visibly above in rank shrugged. The Doctor visibly was nowhere as susceptible to the aphrodisiac as expected, but this could be changed easily. "Do you realise just how much this discovery, this possibility might give us? Our planet would go up in planetary rank by hundreds!"

"She is human, no matter the species of her boyfriend!" Subject-3081 objected. "You, above all, must know what is going to happen if we don't follow the unspoken rule to never harm our clients!"

"This is no harm. This is assistance! Improvement!"

With no further objections heard from whoever might have dared to oppose him, the one in command smirked. "Double the strength."

The effect was immediate. Both the Doctor and Rose have felt it, the increased sensation of – lust, to put it nicely – making them want to forget everything and snog… shag the other into oblivion… because that was what this whole life was about?

This has been the desired effect those responsible for this must have expected. But this was too much. Even for someone as weak as a human. Rose could not think clearly, only seeing the Doctor close to her. The wish to snog him has always been there… The human has long ago convinced herself their relationship was never, ever going to get any further than this.

"D-D-" Funny how even her vocal chords refused to work in this wicked place… Rose did not dare to move away from him, keeping both of his hands in hers… just in case one of them was going to give in to the effects of the aphrodisiac. She could not be sure if she were not going to be the one to give in to the seductive feeling first.

"Make a guess. Is she trying to tell her lover to remove her dress or all she wants is have his dick inside her?" The subsequent laughter echoed all around the place. "The increase in dosage is working, I'm telling you!"

Too bad for the ones experimenting on them (and luckily for the two time-travellers) they have had no idea about the real situation between them…

Apparently, the Doctor could not find his tongue as well. This was enough for him to attempt fighting the unknown forces… But not enough for some of his wildest desires to go away. "R-"

"They have asked for romantic. As you appear to know humans so well, give them moonlight. Give them music."

The man in command, Ri-2 (for Ri-1 was long gone… possibly for three hundred years) was already nourishing the upcoming success this union of two species would bring him. The room was illuminated in natural-looking moonlight at once. "Not here, you imbecile! Outside!"

The Doctor pulled Rose closer to himself, only half-realising this was the first step in letting go of everything the unwritten Time Lord –companion relationship rules might have said. But Rose was so beautiful and clever and enticing and admirable and sexy and- He freed his hands from hers without a word – it was unlikely he was going to be able to say something out loud, anyway – and led her outside.

Nobody stopped the couple from going out. It has all been a part of the bigger plan.

The almost sticky thickness of the atmosphere was gone the moment they were no longer in the room. The sudden sensation of freedom has made the Time Lord remember his gob at once. "Rose- The full moon is beautiful tonight! Come, let me show you…"

Rose exhaled in relief. At least some fresh air was undoubtedly going to clear her thinking… right? The wish to stay close to the Doctor has but intensified… as has the wish to kiss him. And more, but this much was forbidden. This must have been the effect of their bodies touching. Nothing else.

"Doctor…" Rose looked around in admiration and distrust. She has made out this was still the same place, the same building, some sort of a garden, something like the TARDIS could create. "This… isn't real, yeah?"

"Nope, it isn't. But what does it matter?" He breathed into her hair. "We could just-"

"It matters. I want some real moonlight. Some proper music. Not-"

She started at his following words. "You are the most amazing being in all of creation, Rose Tyler."

"Really?" The girl smiled at him fondly. It can't have been his idea to land them in the middle of something so- so- revealing? Disturbing? The effect of the aphrodisiac seemed to have only been growing stronger. This entire place - including the outside – must have been fake. However, Rose did not care half as much any more. She loved him. He must have fancied her somewhat as well. Nothing else mattered.

"Of course, Rose. I have meant every word I said." Because it is this place, and this place only, where we can do anything we want. Rose must have been too ignorant to notice… or refusing to.

The Doctor changed the subject instead. "Can you hear the music, Rose?"

"Strangers in the Night?" Seriously?"

"I know! Can anything get more cliché than that?" The Doctor shrugged. "At least they must have some recordings to fit our cause, right, love?"

Rose shuddered, suddenly feeling responsible for both herself and the Doctor, who seemed to have been enjoying this impossibly disturbing situation the drug has placed them into immensely. The weird change in the atmosphere surrounding them has only made her more self-conscious. She needed to get them both out.

Meanwhile, the ones in charge of creating a sensation were growing uneasy. "Human. Unable to take it, hm?"

"I'm sure this can still be fixed!" It couldn't, as it has all started wrong. But all there was left for them to do was watch their clever plan fall to pieces.

"You should take me to that planet where the moon is-"

"Of course, Rose. Anything." The Doctor understood exactly what was happening… They were being toyed into making love, likely with everyone watching… He could never allow this to happen. But one kiss, just one, it wouldn't hurt… Before he could utter this request, Rose spoke, her voice no louder than a breath.

"Take me back to the TARDIS? Please?" A new wave of barely controllable desire has made Rose do the most foolish thing in this complicated situation, the closeness making her tremble in need. She whispered into his ear. "Please?" She repeated.

"Right now?" The Doctor sounded hurt. So much of the incredible expectations.

"We need to return first. Need to find out what we really feel for each other."

The gravity of her voice has reminded him of her situation. "It's a good thing I have pockets," he giggled bitterly, his breath brushing her ear, a sonic screwdriver in his hand. "Hold on!"

They have materialised on the steel console room floor in the TARDIS. Rose smiled at the Doctor sadly. "Have I ruined your plans? I think I have?"

"Only one, Rose."

"Sorry," she muttered. "This trip has only made me feel all sorts of dirty. I am off to take a bath." Her tiny and sparkly TARDIS-blue dress was off her in a moment.

The Doctor gulped. It was now or never.

"Rose?"

She froze.

"If it's of no difference to you- my bathroom is closer and is much more spacious. Generally, one much better than the tiny one in your room-"

The companion bit her lip. The effects of the aphrodisiac were gone as soon as they have entered the ship… Or were they?

"Sure. I don't really see why not."

A/N. I know this is nowhere as drastic as I could have made it. Please, tell me what you think. :) It means everything to me.
