So this is just something that started off as a 11/Clara one-shot set just after Nightmare in Silver but will more than likely turn into a series. Note- I do not own any part of the Doctor Who series, no characters, concepts or storylines. Enjoy!
"Do you think I'm pretty?" The question had lingered in The Doctor's head ever since Clara had asked him. Of course he did. He had just thought of an almost insulting comment to cover up for his true feelings. The Doctor was good at that, always covering up his true emotions. But with Clara, everything is different. She's the impossible girl, and there's just something about her, something The Doctor just doesn't know how to deal with. All he knew was that his feelings were dangerous. Those feelings could destroy galaxies. It was a place he didn't want to be put in, and yet he longed to be placed in that precise location. He wasn't sure what to do, which was something that perplexed him. Just talk to Clara, or leave it alone, to rot in his mind and turn into a ball of regret that drives him crazy until his last word. And then, and only then, would he be free from the burden of his own feelings and emotions. The Doctor hastily decided to talk to Clara about his emotions, maybe against his normal judgement.
"Clara! Great to see you again!" The Doctor exclaimed, nervous beyond belief.
Clara just smiled and looked at The Doctor. "So where are you whisking me off to this time, space-man?"
"Well, I don't know. Actually- no, never mind." The Doctor was stuttering.
"Spit it out" Clara said, slightly suspicious as to what The Doctor was going on about.
"Alright, here goes. Clara, you-" The Doctor sighed. "There is something about you, Clara, and the fact that I can't pinpoint exactly what it is frustrates and intrigues me at the same time. You're impossible, everything good in this universe in one little brunette package, the most amazing woman I've ever met." The Doctor was staring, almost gazing, into Clara's deep brown eyes.
Clara looked away to the side, in a contemplating gesture, and quickly turned back to face The Doctor. She took him in a surprising, passionate kiss. For a few seconds, The Doctor was stunned. But he was sharply pulled back into reality when he realised what this meant. The kiss broke off and he stared back into Clara's eyes, in an almost confused demeanour.
"Clara, I-" He was cut off by Clara's index finger tenderly put over his lips.
"Shhh…" Clara quietly whispered. "If there's anything you've taught me, it's seize the moment, and don't be afraid." With this, Clara hastily undid The Doctor's tie, pulled off his coat, his vest, and soon unbuttoned his shirt all the while still kissing him. He brought her closer with every breath, unzipping her dress from the back. Soon, Clara was leading The Doctor into his bedroom. They fell onto The Doctor's bed, in a tight embrace. Both of them knew what was to happen next, and both of them were anticipating it.
