Amp powered on and up? Yep.
Bass plugged in and tuned? Check.
Kick-ass song in mind? Uh-huh.
'Let's see if this helps-' Marshall-lee thought grimly, running his fingers lightly over the strings of the axe and listening to the distortion. After upping the gain just a few more increments, He started to play.

'Scotty doesn't know
That Fionna and me
Do it in my van every sunday

She tells him she's in church
But she doesn't go
Still she's on her knees
And Scotty doesn't know-'

She hadn't been on her knees though. She had been on her back, writhing and twisting underneath him. At first it had seemed sexy, but then she had kept shutting him out. She just wasn't letting herself go, and letting him in. He wanted her to relax, not completely but just to be okay with- No, focus!

'Fionna says she's out shopping
but she's under me and I'm not stopping

'Cause Scotty doesn't know
Scotty doesn't know
Scotty doesn't know
Don't tell Scotty
'Cause Scotty doesn't know
Scotty doesn't know-oh'

He had stopped. He had stopped because it felt.. wrong, and he could feel that she wasn't ready for it. He had expected some resistance, and in a way he had been looking forward to the point in time when she would finally yield to him and let him take her. When she finally acknowledged that she was his, and he owned her. But she just wouldn't.

' I can't believe he's so trusting
While I'm right behind you thrusting
Fionna's got him- Fionna...'

Marshall-lee sighed and gave up, fingers limply trailing off the strings as the last strains of sound died. Gob-fucking-dammit. He was so bloody confused.
He had gotten tired of fighting for a weak sense of morality that defied his own nature, tired of pacing back and forth. Eventually, he made it to the mindset of 'Fuck it' (apathetically and literally) and that's when he'd shown up at her house. Tied her down and forced his access without her permission. Tasted her creamy magic.
He knew that the simple fact she had allowed him to get as far as he had showed that she didn't really want to stop him, on some level. She was far too strong to actually let someone take advantage of her like that if she really, really didn't want them to.

But the fact that she continued to consciously resist even when she was obviously enjoying what he did to her had skewed everything from his perspective, and made it seem far too rapey. Creepy and wrong.
He had started to get that feeling as he realised how tense and nervous she was, felt how her body nearly cringed away from his tongue. She was turned on, but she was frightened. And that's why he had had to leave, right then and there, or at the very least to get away from her. Because if he hadn't, he wouldn't have been able to stop. He would've become too invested, too frustrated and he would've taken her whether she wanted him to or not. And while he wanted many things from Fionna, he didn't want to hurt her.

Marshall-lee burst out with an embittered growl, roughly pulling the guitar strap over his head and almost carelessly throwing his bass onto the couch. Fingers fisted in his hair, pacing back and forth.
The second he had gotten off of her, his mind ('mind') screamed at him to get back in there and finish what he'd started. That had been the biggest mental argument he'd inflicted upon himself in quite some time. And it didn't exactly help that the entire time, he was desperately trying and failing not to savour her flavour.
She hadn't been that wet. Just the beginnings of arousal. But it had been enough for him to taste, and damn. Smooth, creamy, a little salty but somehow sweet at the same time. Like... like salted caramel, but completely different. It had taken everything he had not to abandon the darkened corner he had concealed himself in as he panted and guiltily licked his lips. It had take everything he had not to give up on the faint sense of discomfort that kept him there and just succumb to his desires. (terrorising, stealing, manipulating, general dickishness? Fine. Sadism and Rape? No. He was evil, but he wasn't psychotic.)
If it had been anyone else, literally anyone else, he probably would have kept going. Sure, he would've felt bad afterwards but sexually frustrated killing machine here. On the scale between human and animal, vampires are definitely in the middle.
He would use people like playthings and sex toys when they meant nothing to him, because he knew they either couldn't or wouldn't stop him. But not Fionna.
He couldn't do that to her, because she meant more than nothing somehow. She had managed to worm her way past that realm in his list of priorities and become something he actually placed value in. And now, the way he wanted her, specifically her, was unfamiliar to him and he didn't know how to gauge it. How far he could push it without hurting himself too.

Marshall-lee resumed floating and sulkily went into the kitchen to look for something to eat. No matter how minutely he examined this, he still didn't understand. So there was no point in just thinking on an endlessly loop, it wouldn't achieve anything beyond making him remember the way she had tasted for the thousandth time. 'Cause she had tasted fucking amazing. She had been so warm, the occasional bolt of heat arcing quickly through her whenever he hit a new limit. Gob, if only he could go back there now, if only he knew he had enough self control and that she would open her legs willingly...

The images of her flooded his mind and he leant back against the kitchen bench, trying his best to get through the button on his jeans but the fabric of his shirt kept getting in the way. He floated a few inches upwards and half-sat on the edge of the bench as he pulled the collared shirt off over his head, then let his shoulder blades hit the wall as he undid his jeans and pushed them down. They dropped down around his ankles as he pulled his semi-hard cock out of his jockey shorts and started stroking it with his right hand. He hadn't given himself any release since he was stuck in that bathroom, and considering all that had happened during the night, it was long overdue. Glob, that bathroom...

He wanted to catch her just after she had gotten out of the shower- or bath, whatever- but befored she towled off, when her body was still slick to the touch and the room was full of steam. She'd already be hot and flushed, a pinkish colour across her cheeks and her breasts. And this time, she would welcome him, she would want him as badly as he wanted her. She would moan and pant when he pulled her nipples into his mouth, biting on the tip and making her fall to her knees as she cried out.
' Ah! A-ahh.. Fuck-' Marshall suddenly hissed, unprepared for the shock of pleasure when he ran his fingers over the head, spreading precum to ease the friction. This was the hardest he'd been in a while, diamond-like in his hand as he grabbed the shaft and tugged. He arched his spine slightly and flipped his hair back when he tipped his head against the wall, resuming the fantasy.
Then.. then she'd lie back, leaned against the side of the bathtub with her legs spread wide open and her feet tucked under her butt so that her hips were pushed forward. She'd run her hands down her body and pant and beg for him to take her. And he'd be able to watch her drip, see her shine with her need for him.
'Marshall-lee.. Uh-uhh.. please, Marshall..'
And then he would lick and suck and drink, holy fuck- he would drink her dry. She would scream his name as he played her body like a fine instrument, bringing her higher as quickly or as slowly as he wanted. He would own her body, own her.
' Oh, Fuck me, Marshall.. aahh.. ah, M-Marshall-lee!'
And then he'd feel the shock of heat, he'd hear her say his name and watch the torture on her face turn to ecstasy as he made her come...
' Mmf... Uh, Fionna-AH! Hhhaah!... hah..'

Marshall-lee bit his lip as semen dripped down his fingers and splattered onto the floor, swallowing hard then opening his mouth as he inhaled deeply. F-fuck... that was more then usual. But then usual had kind of gone out the window in the past day. He didn't normally have to jack off more than once a week (Immortals feel things more intensely then mortal species do, comparatively. It prevents them becoming bored with existence.) But he'd needed to twice in the space of less than twenty four hours.
He had literally never been so horny, ever. It was fucking insane. He needed to get a grip on- on whatever this was so that he'd be able to function like a normal person. So that he could see, or even just pass by Fionna without immediately wanting to have sex with her. So that he wouldn't end up murdering someone he would regret killing just to help the frustration. And so he could get on with his life (death).
He hoped that since he'd taken the time to hurriedly untie Fionna and redress her (as clinically and with as much detachment as he could. He basically pretended to be Gumball) She might have woken up this morning and thought it was all a dream. Hopefully.
And even if she hadn't, if he avoided her for a little while then acted like it hadn't happened next time he saw her, she'd forget it or write it off as him being a d-bag. Which was preferable than her trying to pursue it, because by making him talk with her about it, it would only make him want to bed her again. And again. And again.
What the fuck was wrong with him?

'Hey Cake... I-I'm gonna go for a walk, okay?' Fionna said, shouldering her bag and walking nonchalantly over to the central tree-trunk. Cake was playing Beemo in the lounge, her little pink cat tongue sticking out in concentration.
' Yeah sure, baby. Be careful.' Cake told her absent-mindedly, before yelling at Beemo for killing off her character with a lava pit that 'totally wasn't there before!'
Fionna left hurriedly, heaving a sigh of relief when she was outside and saw the sun shining brightly. Marshall-lee never left his house when it was sunny unless he had a damn good reason. So she wouldn't have to confront him about her dream, or deal with thinking about what it had inspired her to do when she was in the shower this morning. She had a purplish semi-circle bruise on the inside of her forearm from using the flesh as an impromptu gag while she knelt in the bath and thought about what would've happened if dream-Marshall hadn't decided to bolt. Which actually, was kinda weird for a dream. They are all over the place, but having him disappear was still a fairly sharp 180 to make.
However, the alternative to an odd dream was that it had really happened, and that was completely insane. No way would Marshall have actually snuck into her room at night and tied her down like that. He was fairly daring, but she didn't think even he would have the balls to try with Cake barely three metres away.

But the weirdest thing was dream-Marshall had agreed with her when she had accused him of being in the treehouse with her. She would've thought he would deny it, just because her mind would want to put her back at ease.
Considering it now, it really did seem like the only possible way he still would've been bleeding. But if he healed so fast then why did he ask for a bandage in the first place? Why didn't he just run off and wait to heal, without having the whole awkward confrontation that meant she now knew he had been there while she was uh.. busy? Not to mention his whole speil about support structures. Puh-lease. He had to have heard, there was no way he could be that unintentionally terrifying.
But then that begged the question: How did he even hurt himself if he was just hanging/ hiding in the treehouse? He had become offended and hissed at her when she asked, so it was probably something shameful. Thinking of this particular trait triggered a memory for Fionna, but before she had time to fully realise it she was surprised by the sensation of a cold droplet hitting the back of her neck.
' Ah! What-' Fionna squinted up into the sky and realised she was walking right into a sunshower. Grumbling under her breath, she hoisted her backpack over her head and sprinted over the hills towards a small group of trees a little way away from the edge of a forest. The sunshower became heavier as she ran, pelting her with penny-sized drops of water before she managed to reach cover.

When she reached the grove of trees she sat down against one of the trunks and pulled off her rabbit hat, wringing out the water into the damp grass.
Fionna believed she was alone, but after putting back on her hat and inspecting the area surrounding her, she realised that this was in fact not the case. She could see the tip of a brown boot poking out from behind one of the other trees and figured that it was probably someone else who was taking refuge from the rain. However, she stealthily reached into her backpack and drew her thorny sword, just in case.
Fionna crept forward in a crouch, slowly poking her head around the corner of a bush at the foot of the tree this other, unidentified person was resting on. As soon as she recognised him though, she dropped the sword and stumbled over to him (she tripped as she stood up).

' Flame prince!? When- wher.. what are you doing here?' She exclaimed worriedly, noticing the darkish brown amber he had faded to instead of his usual bright orange. Flame Prince looked to be almost comatose. When she touched his shoulder, trying to shake him awake, he was worryingly cold. Only about the temperature of a warm bath.
' Flame prince? Hey, FP c'mon!' He showed no reaction beyond a faint groan, though Fionna noticed he was steadily heating up, responding to the contact. Encouraged by this, Fionna wrapped her arms around his waist with some difficulty and pulled him up against her, reasoning that her body heat might help him dry off faster. He had gotten heavier- actually it felt like he'd gotten bigger all-round since she had last seen him. Which had admittedly been a while. He'd gone off to 'figure some stuff out' after their rather luke-warm (ironically) attempt at a relationship. Nobody blamed anybody though, and she held no animosity towards him. And right now, an old friend was a welcome distraction.
' Fionna, what... I'm either dreaming or stupidly lucky.' Flame Prince murmured a few moments later, just when Fionna was about to back off. The temperature of his skin was starting to become painful.
' Dude, what're you talking about?' She questioned, then cringed and finally let him go before he burnt her. He still looked a little less fiery than usual, but he'd be fine soon.
' That as soon as I'm flaming out, you happen to show up. The one person who knows exactly how to fix it. That's so unlikely.' Fionna laughed, and sat down cross legged next to him as he finally moved, leaning forward and pressing a hand to his forehead as he winced. His hair fell over one eye, still damp. Even that had gotten longer. How much time had passed since she'd last seen him?
' Hey, don't question the gifts of the universe.'
' What, like nearly passing out 'cause it rained when it was sunny? That seems more like an assassination attempt then a gift.' Fionna rolled her eyes as he shook his head and his hair suddenly flamed up brightly, turning into a mohawk that brushed his shoulders near the bottom. Wow. Looked good.

' Anyway, how ya been? I haven't seen you in forever, Pocket-rocket.' Flame Prince raised an eyebrow at her, an involuntary smile appearing on his face.
' You still call me that? You haven't changed at all, Blondie.' Fionna punched him in the arm then accepted when he stood up and offered her a hand. Almost immediately his eyes widened slightly and he looked her up and down.
' Wait, I take that back.' Fionna crossed her arms self-consciously, and Flame prince grinned at her knowingly.
' I mean, now you're even shorter.' At her immediate thunderstruck reaction he laughed, and copped her retribution-punch without complaint. However he was right. They'd been roughly the same height when they parted, but she barely came up to his chin now. Though those boots did have heels.
' Oh, everyone's a comedian.' Fionna griped and Flame prince shook his head.
' No, but seriously, you look really different- in a good way. Don't actually know what I expected when I haven't seen you for a year and a half.' Fionna paused for a moment at this, looking at him incredulously. A year and a half? Really?

'...Wow. I hadn't realised.. wow.' Fionna said, looking down at the ground and laughing at herself. She felt bad for losing track of him like that, especially after how he had left. Flame prince touched her shoulder and she looked back up at him. There was nothing blaming her in his smile, just a painful look of familiarity.
She hadn't realised how well you could still know someone when you hadn't seen them for such a long time. It hurt to comprehend just how much she still cared about him, and placing that on top of the stress she was experiencing thanks to her confusion with Marshall- Maybe an old (boy)friend really wasn't the best kind of distraction right now.
' I was the one who left Fionna. But yeah. Maybe I disappeared for longer than I should've. I missed more about this place then I thought I would... I really missed you.' Fionna held his eyes for exactly a milisecond after this revelation then looked back down at the ground, feeling something drop through her stomach and writhe around in her intestines. Jeez, what was it these days with men affecting her lower digestive system? It was an extraordinairly uncomfortable sensation, so she surreptitiously folded one arm across her belly as she minutely inspected a tiny pink flower next to Flame Prince's foot.
' I... Do you regret it? Do you wish you had stayed w-with.. Uhm, stayed here?' She found herself asking and almost immediately wishing she hadn't. The moment of silence that followed made the squirming gnawing sensation increase tenfold and start to devour her kidneys.
'... No. And yes.' Fionna waited for him to explain, feeling like the anxiety monster in her gut was attempting to climb up her trachea. Flame Prince's feet shifted slightly and Fionna risked a quick glance upwards, before determining it was safe to look at his face when she realised he wasn't watching her anymore.

' You wouldn't believe some of the stuff I've seen, Blondie. There's just so much stuff you can't find out by being told and staying in the same place to dream about it. But then when you're away and seeing it for yourself, you're dreaming of the people back home.' Flame Princes looked back at her and Fionna manged to hold his eyes this time, determined to stop being such a wimp. He was the one that chickened out this time, looking down at his nervously twisting fingers.
' I'm... I like that I've been places, seen and done it all before I had to make my decisions about what I'm gonna do with my life. But I kinda wished I had waited too. So that I could've maybe... ' He sighed in frustration and Fionna saw his brow furrow and an apricot-coloured flush appear on his cheeks.
' Fi, I don't want to start anything with you again. I've barely been back a week, and I don't want everything to just go back to the way it was. I want to move forward in the same place. I-if that makes sense.' Then he sighed and smiled at her in a somewhat bashful manner.
' But I'd be lying if I said I didn't wanna kiss you one more time, even though I know that's stupid because I'll burn you. Just for the sake of it. I really, really missed you.'

Fionna smiled at him, thinking about what he had told her. What it would mean to him, and how great it would be to forget about all the complicated happenings she was wrestling with internally and reconcile with a boy she used to love.
' Just one last kiss? For old times' sake?' She questioned, and Flame prince looked at her in surprise.
' Yeah, but Fi.. I'll burn you. It's just-' Fionna grabbed his hands and tugged him out into the rain. While they had been talking, puffy grey clouds had slowly closed in but their tiny grove of trees was still in the middle of the patch of sunlight.
Fionna saw him wince as the water hit his skin, and the heaviness of the shower soon soaked her through. He cooled down very quickly as she dragged him further out onto the hills.
' One last kiss, and you promise that no matter what happens and where you decide to go, we'll stay friends?' Fionna asked him, stepping forward and wrapping her arms around his waist. She knew that he heated up when she got closer to him, but hopefully the combination of being with her and the rain would keep him at a temperature she could manage without him burning out.

Flame Prince replied to her question by leaning down and kissing her firmly. It was like drinking burning hot tea, but Fionna didn't mind. She immediately went back for more when he broke away, letting him know that she was okay and he didn't need to worry about her. As their mouths synchronized, like old dancing partners recovering half-forgotten steps, she heard him give a tiny sigh. Then his hands moved from where they had been placed chastely on her waist and wound around her shoulders, surrounding her in a pleasant warmth despite the rain that continued to drip on to them.
There was a sense of nostalgia, and that painful familiarity that Fionna simultaneously hated and adored. It felt bad to know that she was essentially using him as a channel for her frustration while constantly being reminded of how incredible doing this with him used to make her feel. But that same familiarity meant there was no unease, because they both remembered that incredible feeling and how to provide it.
He was a distraction, and he was her friend. She trusted him. For now, that's all she needed, and she suspected that was all he needed from her too.

Author's note: Whoo, this was a long chapter. It could've been even longer, but I felt like this was a good place to end it. Man, I wish I could see all you hard-core Fiolee shipper's faces right now. I'll bet your shooting daggers at me through your webcams xD I do ship Flameonna to a certain extent, but it's not my favourite ship and if you've read the original for this, you know who ends up banging. I'm throwing FP in here as a side character, possibly to torture Marshall just a little bit more and possibly to make Cake's presence even annoying-er. You'll just have to wait and see :P
