Five kissed like he couldn't quite believe it really was happening. Which, when you thought about it, made sense considering the amount of time that passed since they've first met, and the number of years he had lived since they first kissed, back in his third body.
He kissed her at the most random of times, usually just a small peck but, occasionally, a long, consuming one that took her breath away. These kissed had her leaning closer, but he always pulled away first.
He left it with a small smile that made her stomach twist in excitement, butterflies making themselves known as her heart skipped a beat.
Six was a tease. Eva had learned that quite early along their relationship. She accepted that – not that she had much choice on the matter. And that was without talking about their kisses.
He liked to bite her lip as he tested her mouth, checking how much could he deepen the kiss before Peri cleared her throat, bringing their attention back to the situation they were in.
When he pulled back, it was with a smirk and a mischievous look in his eyes that left her wanting more.
Seven's kisses were always short – but they also always got the point through. It was the same point she was trying to pass on every time she kissed him.
You are mine. I am yours. Nobody but me gets to kiss you, just as nobody but you gets to kiss me.
She suspected it had something to do with the events immediately following his regeneration, but knew better than to comment on it when he pulled away with a short nod.
Eight was the one who first learned the truth about the potential quality of long kisses – how satisfying a kiss could be, even if it started slow.
In fact, it was with this Doctor that Eva would say they have completely stopped kissing and had started making out, especially with the way his hands travelled all over her body – something that only his sixth self had attempted before.
She slapped his hand away, once or twice, but did nothing more as he put it back in its place.
The War Doctor not once initiated a kiss, but he always returned it once it had started.
His hands never dared to travel over her body, and he never tried to deepen the kiss, but Eva knew him well enough to know he was cherishing every moment of it.
He was always the one to pull away, saying he didn't deserve her, and though often she would let the kiss fade, sometimes she would simply tell him to shut up and pull him closer.
Nine kissed like he was scared she's run away any moment. With the horrors of the Time War still fresh in his mind, he still found it hard to believe that she hadn't yet.
He would hold her tight, pulling her so close that she could feel his hearts beating faster. She would wrap her arms around his neck and he would pause, disbelieving she would choose to be so close to someone like him.
He would pull away reluctantly, but she would smile with the promise of more.
Ten always hesitated for a moment before kissing her. It only grew stronger after they lost Rose, and even stronger after Martha left.
Eva didn't even notice that short pause at first, but she was unable to ignore it once she did. The way he paused, only for a moment, before capturing her lips with his.
When he pulled away, long moments later, Eva was left confused and slightly dazed.
Eleven kissed so often that if she didn't know better, she would have thought the kissed were meaningless. Luckily, she did.
There was a look in his eyes that she couldn't quite translate as he pecked her lips, pulled her close or allowed his lips to trail her neck.
Still, whenever he pulled away with his signature smile, the thought seemed to fade away from Eva's mind.
Twelve kissed her like she could fade away any moment.
His hands ghosted over her arms, scared to hold her too tight lest she'd disappear from between his fingers.
When he pulled away, a sad smile tugging at his lips, he refused to talk about it. It didn't stop Eva from wondering what could have possibly changed.
