I lot of people liked my last fic, so when inspiration hit, I started writing right away. This one will have a few chapters, but will probably be complete in a few days :)

I'm not affiliated with Adventure Time or Taylor Swift.

Put your lips close to mine

As long as they don't touch

Out of focus, eye to eye

'Till the gravity's too much

And I'll do anything you say,

If you say it with your hands

And I'd be smart to walk away-

But you're quicksand.

It was so, so dangerous to fall in love with a vampire. But Fionna always found herself running headfirst, fearlessly into danger, so it's not like this was anything new.

Of course, to Cake or Gumball, going out with that "bloodsucking creep" (they knew he never actually drank blood, why did they have to be so dramatic?) would be worse than fighting a dozen Liches at once. Which was totally blowing things out of proportion.

Not that Fionna and Marshall Lee were actually going out. After all, he was waaaaay out of her league for one thing, and for another, it didn't actually matter if they went out, though it would be nice. But it wasn't like she needed to be with him to validate her existence or some junk like that. Even so, she did always wonder what it felt like to kiss him, to hold him – and not just in a headlock.

She'd never tell him about her crush anyway, not because she was afraid of rejection, but because she didn't want their friendship to get all weird if he felt one way or another. Anyway, he was always messing with her, trying to get her to say the "L" word to him, so if she ever actually did, he probably wouldn't believe her anyway (...would he?).

And, Glob, how he loved to mess with her! Like this one time, for example-

"Nice, dude!" Fionna clapped after Marshall Lee had played one of his newest songs for her. He often came to play them for her to see what she thought – after all, she was the only musically inclined – meaning, she could sing well enough - person nearby (when Cake wasn't available, anyway. And Cake was a bit too critical anyway – apparently, dulcimers are so much better than guitars? Pft. Whatevs.). She always complimented him – which only boosted his ego – but wasn't afraid to give him criticism when necessary.

"Ya think?" he asked, setting his axe guitar down, leaning it against the couch in the treehouse's living room that the two were sitting on. "The second verse wasn't too...I dunno, cliché?"

"Maybe a little..." Fionna said thoughtfully, "But like, it really had some good emotions goin' through it! It was really good, I dunno what else you want me to say." She shrugged.

Marshall smiled, but it quickly became a smirk. "What do I want you to say?" Uh-oh. She knew that tone. "Maybe I want you to say how strongly it made you feel," he came nearer to her, "Maybe I want you to tell me how it made you feel something for me," that stupid smirk on his face grew as he came closer – now she was backed up, laying on the couch, and he was floating mere inches above her. "C'mon, Fi, didn't your heart beat just a little bit faster, because it made you think of me?" he laughed.

Ooh, he was one arrogant bastard. But...he was also a correct arrogant bastard. Not that Fionna would admit it...she swallowed – his face was mere inches from hers, and oh, how she wanted to just punch that stupid, knowing smirk off his face! But she couldn't. Why? She'd done it before, why was this time...why was her heart pounding, oh Glob, her face was turning red, she could feel it. Their eyes were locked – was is possible for your heart to beat so fast that it stopped? Fionna was pretty sure that was what was going to happen to her right now, because judging from the proximity of their faces, she was pretty sure that he was going to kiss her.

Unless, of course, she kissed him first...

'No, no! He's just messing with you, like always!' she thought, 'He wants you to react, he wants you to do something stupid so he can laugh at you or whatever!' But at the same time, she didn't care. Even if it was some joke or whatever, her body seemed to be detached from her mind. It ached to be touched – to feel his hands on her waist and his lips on hers and -

This was too much. She was actually about to close the distance between their mouths (mostly for fear that her heart would stop if this continued on much longer) when suddenly, letting out a laugh, he just stopped floating, flopping down on top of her.

"OOF!" Fionna coughed as he got off of her, regaining his spot on the couch, "Jeeze, dude, ya trying to make me puke?"

"Sorry," he laughed, putting his hands being his head suavely, "The way you were looking at me, I couldn't think of any better way to take you by surprise than just dropping like that."

"Oh, no," Fionna smiled slyly, "I meant putting your face so close to mine."

Marshall crossed his arms and rolled his eyes. Fionna stuck out her tongue, and they both laughed.

'I really dodged a bullet there,' Fionna thought. 'Would I actually have kissed him? Stupid emotions!' she lightly punched herself in the head, trying to clear it.

"Uh...Fionna...you okay?" Oops. Marshall was still there, giving her a rather concerned look.

"Uh...Y-yeah...Just uh..." before Fionna could come up with an excuse, Marshall's hand shot out over her mouth.

"Shh!" he quietly exclaimed, "I hear Cake coming home! C'mon, quick, let's hide and scare her!" he pulled his hand away from her mouth and instead extended it out to her. She looked at him, then placed her hand in his, and he flew them to the closet.

Never would Fionna pull a lame prank like this on her sister otherwise. But she wouldn't leave Marshall hanging, either.

And together, in the closet, in the dark, she couldn't help her heart beating a little faster than usual.

It was so dangerous to fall in love with a vampire. But Fionna, the strong, brave, stupid human did anyway.
