The Doctor felt guilty, so very, very guilty. How could he be so stupid? He was an old, thick man who had had his brains completely scrambled by a beautiful woman and her unbelievably soft lips. He had unintentionally hurt that fantastic woman, with whom he was rapidly falling in love. He couldn't remember the last time he had felt so conflicted and confused. He'd felt grief on so many occasions for so many different people, but this was different. He mourned the woman who had died in the Library, at the time he had found her to be infuriating and now he looked back in awe of her. She had seemed upset that the man she loved didn't know her; she had such strength and courage and just carried on like normal, flirting with him and saving everyone in the Library. He was afraid then when it was his turn, when she looked at him blankly with those incredibly deep blue eyes, usually filled with love and humour, he wouldn't be able to hide his pain as well as she had.
He felt so guilty because he couldn't save her and even guiltier about that kiss, it shouldn't have been like that. He didn't even realise the significance of his words "There's a first time for everything" and that expression on her face, like her soul was being crushed. It was two hours after he he'd flown the TARDIS away from the stormcage facility, after he had spoken to Amy about the pregnancy thing (now that had him really worried), the Ponds had gone to bed, and the Doctor was left alone with the TARDIS. She seemed very attached to River Song, he was sure that he had taught her to fly well, but it wasn't just skill that made the TARDIS travel through space and time, she had to want to do it. He was sure that whoever River was and whatever terrible thing she had done, she had a good soul, and the TARDIS was an excellent judge of character.
It was while he was musing on this that the realisation struck him, "your firsts are my lasts". He stopped dead in the middle of the console room; that was her last kiss with him, he had been rubbish and then couldn't run away fast enough! The guilt shot through him like ha had been stabbed and his knees nearly gave out beneath him, he understood the look on her face now and his heart broke for her.
He got that nagging feeling in his stomach telling him he was about to do something extremely stupid, but he didn't care. River was very good at getting him to do stupid things.
He leapt into action as he plotted their destination and the TARDIS was so cooperative with this plan that Amy and Rory weren't even aware that they had moved. He mad sure to land half an hour or so after he had left, River would not be amused if he turned up and found her in tears, she would be embarrassed and angry and take it out on him! He landed silently, took the brake off and everything!
River was sat on her narrow little bed in her cell, with the storm outside mirroring her mood. She had had a good cry as the TARDIS dematerialised. She had always known this day would come, in her timeline their romantic relationship was over, with one rather haphazard kiss. It had still made her skin tingle and her stomach do somersaults as kisses with the Doctor always did, and although he did kiss her back (which was something she supposed), he didn't loose him self in it and just flailed his arms around wildly.
After a few minutes of tears for the man she loved and would never kiss again, she pulled herself together and opened her diary to write her account of their latest adventure. Though writing about his death was hardly going to cheer her up.
That was how he found her when opening the TARDIS door. She had changed her clothes; the stormcage was too cold for that dress. She was now wearing those tight black trousers he liked and a big red jumper. It took him a moment to realise that the jumper had been a favourite of one of his previous incarnations, it definitely looked better on her. River was sat cross legged on the bed with her back against the wall, writing in the blue diary. He had tried to be stealthy but she knew he was there; she briefly shut her slightly red and puffy eyes and took a deep breath before looking up at him with a smile that didn't quite meet her eyes.
"Um, hi." The Doctor had made this impulsive plan but had completely forgotten to plan what he should say.
"You came back because you feel guilty." She stated flatly.
"Yes, no, sort of. It's complicated."
"We're always complicated." She closed the diary and moved over so that he could sit next to her.
He lent back against the wall and sighed. "I had a thing, but I forgot I would need to know what to say. I do feel guilty that I cause so much pain. You could so easily tell me change the future so you wouldn't spend your life caught up in the madness of a stupid old man and his blue box..."
"NO! Don't say that..."
He smiled and tapped her nose "Don't interrupt. I've offered to re-write time for you before and you said the same thing. So I figure that for you to still say that after how much this must hurt you, my future must be pretty good."
He was expecting the usual answer of "spoilers" instead she smiled and said "The best".
He grinned back "Ok then. Let's get started."
He grabbed her hand and tried to pull her off the bed.
"Doctor! I can't come with you now!" she tried to free her hand.
"Why not? And don't say because you made a promise, because chances are that promise was to me. In which case I will take full responsibility for making you brake that promise as I am kidnapping you against you will." He smiled broadly at his clever argument.
"Get that 'aren't I clever' look off your face. It doesn't work like that!" River literally dug her heels in to try to stop being dragged into the TARDIS.
"I will even let you fly on the way back so that we land almost immediately after we leave, that way you're not really breaking any promises if you don't loose any of your sentence."
The Doctor looked her over for a second, checking for weapons. He wasn't leaving her here, even if it was just for a few days adventuring, they all needed to do something fun after that weird business with the Silence.
Somehow, with coordination he hadn't thought this body possessed, he grabbed her legs and hoisted her over his shoulder.
"DOCTOR! What the hell do you think you are doing?"
"Kidnapping you. Now do stop shrieking and wriggling, I might drop you."
He set her down in the console room; she darted around him and ran towards the doors, which slammed shut in her face. She pulled and pulled at them but they wouldn't open.
She turned to him, leaning on the doors "That was mean".
He laughed "That wasn't me. I guess that's the problem with the TARDIS liking you!"
She looked sad "You don't even know who I am."
He walked down to the doors and stopped in front of her. "Maybe I don't care that much, though I am very curious. Every time I have met you, you have tried to do the right thing, sure you lie and steal and are far too gun happy, but I've been around long enough to know the good people from the bad. And I trust the TARDIS, she is an incredible judge of character as she gets into the head of every passenger so she has probably always known who you are and doesn't care, in fact I think she likes you better than anyone."
"I don't really know what to say to that," she lowered his eyes.
"Say you'll forgive me for kidnapping you and stay for a little while?"
River smiled and met his eyes "I don't really have much choice, do I?"
He moved a bit closer "You could always knock me unconscious and force the doors open. But you won't do that."
She leaned forwards slightly and put her hand on the front of his tweed jacket "What makes you so sure?"
"Because you don't want to leave." He was so close now she could feel his breath. She didn't move any closer, this was his moment and she didn't want force herself on him, again.
"I'm sure we shouldn't be doing this so early in your timeline." She whispered.
"I've never been one to follow schedules." He smiled and closed the gap between their lips. He had been caught off guard last time and panicked, but he wasn't completely inept and he wanted to make up for that kiss. She let him lead the kiss initially until she was sure this was what he wanted. His arms that had been flailing around during their last kiss went around her waist. She was so perfect, the softest, most kissable lips he had ever encountered, just the right height that he wouldn't get a sore neck leaning down to kiss her. One of his hands slid up into her incredible hair. He had been dying to touch it since he met her, even in the Library he had wanted to know if it was naturally like that or all crispy from styling products. He sank into the kiss, forgetting all of time and space; he couldn't remember the last time he had been so focused on one thing without mentally drifting off on a tangent. The arm around River's waist pulled her closer.
River then forgot her inhibitions about kissing this Doctor, he was kissing her like her Doctor now, and he should know that she was in charge, always. She moved the hand on his jacket up to his shoulder and buried the fingers of her other hand in his ridiculously floppy hair, pulling him even closer to her and kissed him with all the passion she normally would. The kind of passion that often led to clothes being strewn around where ever they were. River pulling him closer meant that he was now pressing her up against the door. He hadn't felt a physical need for anyone like this for the longest time, and he demonstrated this by pushing his hips into hers so she could feel his hardness. He gasped slightly and she moaned, pushing back into him.
Despite his lack of recent experience his hands seemed to instinctively know what to do, but he was certain he was not in control of them! He kept one hand in her hair; his fingers were obsessed with her soft, unruly curls while the other mover up from her waist to cup her breast.
River moaned again and arched into him, breaking the kiss, leaving them both gasping for breath. The Doctor suddenly became aware of where his hand was and quickly moved it away, looking a bit sheepish and a bright crimson blush colouring his cheeks.
She laughed softly "Not that I'm complaining, but really too early in your timeline!"
His blush deepened "Maybe we should consider this trip to be one of those magical moments that exists outside of time and therefore has no bearing on past or future events."
"Whatever you say Sweetie. I do however think that it's just an excuse to get away doing things you wouldn't normally do. But I do remember you quite happily kissing me last time I saw you, so it wouldn't hurt for you to get in the habit of doing it." She smiled cheekily and gave him a quick peck on the lips before stepping away from him and walking towards the centre console.
The Doctor stared at her walking away; surely it should be a criminal offence to have those legs and that ass. She turned, catching him staring and smirked.
He coughed and tried to regain some of his composure. "So next stop?"
A beautiful smile lit up her face "Everywhere."
