It was a sensory overload, focusing on taste and touch. The main sensations were warmth and smoothness and malleability, like if pancakes with butter and syrup had gained sentience and become a beautiful women with shining blonde hair. Marshall felt as if he'd been in here with her for hours, knowing full well it was a dream but beyond caring. He wanted her, needed her so much, and even if this wasn't real it felt real, which was enough. The illusion was only distracted by the scenery around them, which was blurred and formless, simply a pale mass of pastel colours. He had been wearing the clothes he had fallen asleep in when Fionna had first pulled him in here with her, but those had been lost quickly and were nowhere to be seen, proving the dream theory.
Doing this allowed him to fufil the desires without any consequence, but somehow the simple fact that he knew it was just a substitute was keeping him from being satisfied. No matter how many times he took her he came back for more, with virtually no break in between, linked together by touching and kissing and tasting.

The first time had been rough and possessive, tearing into the skin of her shoulder with his teeth and marking his territory as he thrust into her jaggedly and she groaned and panted. When he came, the feeling had been so, so much more satisfying than the night before, though that was a subconscious mental note. The demon girl couldn't have been further away from his thoughts as he kissed Fionna hungrily, treasuring the taste he had never had before. He had kissed her lips, but never her mouth in real life, so he knew this was just a mental approximation, what he believed she would taste like. It was indescribable, too complex and flavourful to explain with words.
The second, third and fourth rounds had been more gentle, more exploratory and curious, seeing how well he had mapped her out. She was so soft and pliable as he held her, completely at odds with her personality and perhaps at odds with how she would really be. But being here with her, like this, even if it was all in his head was definitely better than denying it and stressing. He a little ashamed of himself but he was tamping it down for the moment. He could deal with it when he woke up.

Marshall gently tugged Fionna onto her back from behind, his hand shifting from being splayed over her breast to sliding down onto her hip and pressing into her skin. Fionna sighed happily and turned over, stretching out beneath him and giving him a genial smile when she saw his face, reaching up and running her fingers from the corners of his mouth down his neck and tracing his collar bones, finally laying her palms on his chest. Marshall straddled her on his knees, sitting on her stomach and leaned over to kiss her, slow and hot rather than rough or fast. She purred appreciatively as he sucked on her bottom lip and ran his fangs over the inside, his fingers going into her hair and stroking the silky strands as they fanned out behind her head. In some ways she was behaving like a cat, pressing into his hands where he touched her and twisting her body until he was where she wanted him to be. She reacted to him so well, rebounded against him in ways that he didn't expect but were always, well... enjoyable.

He made a low thrumming noise in the top of his throat when she pushed her hands around on to his back, and rubbed down his shoulders to the base of his spine then up again. He rolled his shoulders, making the muscles flex beneath her fingers and growled appreciatively when Fionna's fingers pushed in and massaged delicately.
Fionna sighed and bit his lower lip, which made him grin as he broke away from her mouth and started to thoroughly violate her neck in payback. She moaned and arched up onto him, the sounds and sensations starting to arouse him again. Marshall bucked against her with a growing sense of urgency, moving his pelvis down until their hips met and grinding them together. Fionna's knee came up underneath him and he elevated his body as she pulled her legs out from under him and spread them wide, placing one of her heels just above his butt and exerting a subtle pressure to tell him to get on with it.
He was more than happy to oblige, groaning in pleasure as he sheathed himself inside her and she shook and gasped, an instant flash of heat warming her body in a matter of seconds and bringing with it a sheen of sweat on her skin. He paused for a second, deep inside her and traced the tendons in her neck with his upper lip, inhaling the scent of her skin and lightly brushing his tongue over her pulse. He could bite her. Take her in more ways then one. But he was distracted when Fionna's thighs clenched and she folded her legs across his ass and placed one hand on his shoulder.
' You okay, baby?' He murmured smoothly, his voice low and rich. Fionna didn't answer for a few seconds, mewling slightly when he licked up the side of her jaw and closed his teeth over her ear, careful not to break the skin.
'Marshall... please...' She breathed, her hand sliding over his skin and holding him closer to her. She sounded so fuckin' sexy when she said his name like that.
Marshall-lee rocked back and forth slowly, savouring how she felt and how he could feel her flexing and shifting beneath him so that they moved together, like a well-oiled machine, perfectly in sync. He didn't need speed to make her cum, only force and he was watching her face when her eyes fluttered closed and she released a high pitched series of moans, her mouth open in a small, perfect red circle. Her finger nails clenched in his back and she pressed herself against him , murmuring his name against his shoulder. Hearing her say that made his breathing accelerate and he sped up slightly, making Fionna squeak and her heart rate jump as his movement caused her to shift up and down slightly on the surface, although the sheen of sweat kept her stuck in place. Marshall groped her breast with one hand and kissed her needily, his tongue pushing into her mouth and coaxing her own into a deliciously imprecise dance while their lower torsos slid past each other in an unceasing rhythm. Their bodies together were like liquid, flowing and wet but also pushing and ricocheting off each other, still two different people but the line between them a little blurred.
His climax was heavy and powerful rather than fast or urgent, and he bit down on his lip and groaned loudly between his teeth to stop himself from cussing when he came inside her.
Fionna ran her hands down his locked elbows as he kept his weight off her, his eyes closed and sweat beads forming on his forehead as he panted heavily. She kissed the corner of his mouth and Marshall-lee turned his head slightly at the contact, searching. Fionna kept her mouth closed and chaste but soft as she pressed their lips together one last time.

When Marshall opened his eyes again, he was looking at the roof of his room, a Cheap Trick poster with a torn corner taped to the plaster. He could swear he could still feel that last kiss on his mouth, but when he flicked his tongue out and wetted the dry skin the echo disappeared.
He propped himself up on his elbows in the bed and pushed his fingers through his hair, unsurprised to find the locks sweaty and stuck to his forehead. The condition of his jeans probably didn't bear thinking about, as they were now stained with several of the fluids that his body could produce, seeing as they had gotten blood on them when Femme had cut him up earlier and he could feel a film of sweat going stale across his skin and coldly dampening his clothing. He slowly shifted his legs off the bed and onto the floor, wincing at how sensitive and sticky his crotch felt, then again as the shame he had been repressing suddenly broke through his mental dam and flooded his entire being. It didn't help that he suddenly became aware that he was starving, and his gut made a loud whiny cry for sustenance and began to hurt.

...
What. The. Fuck.
He had just done her five fucking times in his head.
That was beyond attraction, that was beyond obsession, that was fucking insanity. Or vice versa, rather. She was literally driving him sex-crazy.
He hadn't had a wet dream since he was like, fifty, and even then, it had never been more than once, and the same girl rarely showed up. The insatiable need he had to claim her was consuming him, taking over or interrupting every other need he had. He couldn't sleep without dream-fucking her. He had barely eaten, his appetite waning and his attention so occupied he wasn't even going into frenzy mode (his stomach growled again angrily, protesting this idea). He plain just couldn't think without that afternoon and the night that followed barging in like a fucking medieval raid and storming the proverbial castle of his mind.
This couldn't just be attraction run rampant. He had never lost control of himself like this before, at least not sexually (blood lust was a vampire thing, you got used to it). He liked being the one that threw out the frustrating, knowing wink, that pulled the strings and watched what happened in amusement (in that way, he and Gumball were similar, only Candyballs didn't do it for fun). But somehow he had become the marionette, tugged around and made to dance a mortifying dance. But why? What possible reason could there be for making him so... Fuck euphemisms, so bloody horny? He was a piping hot mess, but it all boiled down to one inescapable fact:
He had a gobdamned nuclear-strength thing for Fionna.

Marshall seethed quietly as he ghosted invisibly through the hallways to the bathroom, convincing himself that this couldn't be his fault, that it wasn't him and he wasn't like this. Cause he wasn't. He wouldn't choose this or let it happen. It was too much fuckin' work to like just one girl when there were so so many who could give him what he needed in the sheets without the emotional support/baggage that came with relationships. He didn't need that he did fine on his own. He wasn't afraid of falling in love persay, he just didn't see the point if he didn't need it. Too much effort.
Which was why this sudden, desperate attraction to a sixteen year old tomboy was creeping him the fuck out.

There just had to be some sort of explanation beyond a freaky-intense round of love (or rather fuck) at first sight. Sure, he liked her, quite a lot. She was fun to be around, and he didn't have to act out or in in order to make her accept who he was. She knew how he was when he wasn't being anything, and she didn't mind that guy, apparently. He appreciated that.
Yes, he had always thought she was hot, or rather he had started to when she had filled out around about her fifteenth birthday. That was when her curves had started to show through her cutesy little outfit, and he had begun to appreciate the view when she was running around doing all her athletic, flexible adventure stuff.
But this wasn't even ballpark to those emotions anymore. This feeling was much, much stronger than that. Almost... instinctual, up there with eating and sleeping (breathing would've been on that list if he still needed to). He needed food, he needed rest, he needed sex with Fionna. Knowing that he needed it, not just wanted it was what was making him so scared. It wasn't something he could just stop or change.
If this was what actual love was like, then fuck... Disney needed a memo so it could warn people about this shit. There was nothing remotely romantic about how much he wanted to bone her. He'd bet his left testicle that Snow White's prince had never wanted to do her so bad he would've jumped her without bothering with the true love's kiss first.

Marshall slipped quietly into the bathroom (really, the only thing that could've given him away would've been his scent) and locked the door once he was inside. It wouldn't actually stop anyone from coming in if they really wanted to, but it let people know he didn't want anyone fucking with him at the moment. He paused for a moment, fingers in his hair again- that was becoming a nervous tic, he needed to stop doing it- before turning on the shower and tugging his shirt over his head.
This couldn't be love, it was too lusty to be something that had a reputation for being so y'know, pure and selfless and all that. Lust was a selfish feeling, and it had a yin-yang dynamic with all the cutesy heart stuff. A dynamic that was completely off balance here, knowing that even though it would probably kill her, he still wanted to rail her so hard. He couldn't help it.
No, this couldn't be love. It couldn't be.

Fuck, the zipper on his jeans was stuck.
You'd think with all that...
Ugghh.

'Fionna, would you be a dear and get my catn- Fionna?' Cake yawned sleepily, stretching down the ladder into the living room and finding it empty. Beemo was sitting in a corner playing with a pair of sock puppets and a button, throwing Cake a reproachful look when the cat looked her way.
'Beemo, do you know where Fionna is?' She asked anyway. Beemo turned around and loudly made the sock puppets converse, giving a clear and rather rude gesture to the calico, who simply rolled her eyes, used to dealing with the contrary console.
Fionna was a big girl, so it wasn't like Cake minded if she decided to go off by herself. But she did like to know when it happened and where she was off to. It gave her a rough idea of whether she should bother checking up on her or not.
But she was in the mood for some catnip and eggs, so Fionna was just missing out, and she could take care of herself. Her loss.

' But... It makes me feel all exposed!' Fionna whined, two bright pink circles adorning her cheeks where they had been glowing in moderation all morning. She had her arms crossed over her chest, covering the rather ample cleavage displayed by the short leather bustier Femme had put her in.
After rifling through her wardrobe and picking the few items that Femme felt had some potential, she had dragged Fionna back to Marshall's house and promptly ignored his only ground rule, rifling through his attic for old girlfriends' clothing. She had turned out to be a dab hand at sewing, and had patchworked the bustier together from a pair of leather trousers that Fionna couldn't pull over her ass, and laced together the front with the ribbon edging of a poofy skirt. Femme had then cut several inches off of said skirt and used it to create a petticoat for an old navy blue pleated skirt of Fionna's that she never wore anymore because it literally barely covered her butt, and it still didn't, even with the petticoat. Femme had then given her a pair of black suspenders to 'keep the skirt in place' (keep Fionna from pulling it down).
' Good! That's what it's supposed to do, show you off to him, let him see what he's missing out on.' Fionna pouted and tugged on the back of the skirt, intensely aware of the fact that every step she took would flick up the back just enough that you almost, almost got a glimpse of her underwear. It was only that long.
' At least let me wear some shorts or something underneath this skirt!' She complained to Femme's denim coated backside, wiggling around as she rooted through some boxes.
' Oh, no way.'
' What d'ya mean-'
' No no, shut up, not talking to you. Look what I found!' Femme said gleefully, waving Fionna over to her. Fionna, grumbling internally, walked over to her and squinted over her shoulder into the box. There appeared to be a couple pairs of handcuffs, several long lengths of silky rope as well as cableties, a couple of small opaque black bottles, and several items Fionna didn't recognise. Femme was chuckling to herself quietly, but before Fionna could ask what was so funny, she shoved all of the stuff to the side and triumphantly pulled out a pair of black leather gloves and a pair of garter straps with lace on the sides.
' These gloves'll just look cool, plus I'm betting since Marshall has this stuff boxed up he ain't used it in a while, so he won't recognise it but he'll still associate it with sex.' Fionna frowned then looked back into the box.
' Wait, that stuff is for sex?'
' All of it. If you're lucky, this won't be the last time you see it, honey.' Fionna eyed the box with some apprehension, before putting the gloves on. The leather was soft and it had a faux zipper embellishment on the arm which made her feel strangely rebellious.
' Hey, gimme your sewing scissors.' Fionna said, taking the gloves back off. Femme raised an eyebrow but handed them over, and made a little noise in comprehension when Fionna snipped the tips off of all the fingers of the gloves.
' That way I can still do stuff while I wear them, but these'll also protect my hands. I actually like these.' She said appreciatively, flexing her fingers. Femme smirked smugly. She was coming around.
'Okay, now clip these to the top of your socks.' Femme said, giving her the garter straps. Fionna laughed out loud when she realised the clips were shaped like tiny rabbits wearing bowties.
' Dude, these are so perfect for me. Look, little rabbits!' She gushed enthusiastically, clipping them on. Femme put a hand on her chest for a moment, touched by how gobdamn precious the teenage girl in front of her was, before getting back to business.
' Then attach the clips on the top to the edge of your undies.' Fionna blinked at her, blushing harder again.
' B-but why? My socks stay up just fine.'
' Because it looks hot, Fionna. Trust me, I know how guys think, they like this. And I mean, we just found these in Marshall's personal kinkstash. He is going to be into it, one hundred percent.' Fionna mumbled snarkily under her breath, tugging on the staps but soon discovered that even though they were elasticated, they wouldn't reach.
' They're not long enough.' Femme frowned unhappily, then sighed.
' Hah. Okay fine, you get your wish. Put on some bike shorts under the skirt and clip 'em to that.' Fionna collapsed with relief internally, picking up the bike shorts Femme had taken from her wardrobe and putting them on beneath the ridiculously short skirt then clipping up the garter straps.

After that, she stood in front of Femme for a moment, letting the older woman assess her visually in the same manner she had been the entire morning.
' Hmm. Missing something. Try on my boots while I go get a thing.' Femme said, quickly pulling off her suede grey boots and handing them to Fionna, then turning into a cat and scampering away. Fionna shrugged and sat down on the edge of a box. She pulled on the shoes, surprised at how well the fit her, and wiggled her toes. The boots had a hard, dark silvery toecap, and Fionna grinned when she pictured how much pain she could bring if she kicked a bad guy with these.
Femme returned a moment later, something denim in her mouth. Fionna watched as she turned back into a person and showed Fionna a denim jacket. The adventuress reach for it, but Femme held it away from her then promptly tore off the sleeves and passed it to her. Fionna raised an eyebrow but said nothing, noting that the jacket had a hood on the back.

She put it on then stood up in Femme's boots, pleased that they had a flat bottom instead of high heels.
Femme looked her over again, then nodded shortly.
' Yeah, I like that. Not too complex, but there's plenty too look at, and just enough kink that he'll have all sorts of dirty scenarios going on when he looks at you. Perfect. I won't bother with make-up, you'd probably sweat it all off anyways, and you're pretty enough without it.' Fionna ignored Femme's monologuing, instead patting at her chest (she wasn't worried about her behind anymore, it was covered).
' I still don't like this top. It doesn't even cover my stomach, I could get stabbed so easy, and my boobs feel like they'll fall out any second.'
' Good. That means it's exactly low enough. And you may have noticed that at least I've dressed you in stuff you can still run around in, 'cause you said that's kind of your thing.'
' Well, it is.'
' And I took note of that.' Fionna twisted her mouth to the side and decided to let it go. She would get used to the precarious top, and it wasn't like she'd have to wear this all the time.
' Well, what do I tell Cake when I come home like this?'
' Just do up the hoodie and say you're trying out a new style. She's you're older sister, not your mom. She should be cool with it.' Fionna laughed once.
' Uhm, you don't know my sister, she practically is my mom now. Though, she has been getting better recently.' Femme shrugged, walking out of the attic and gesturing for Fionna to follow her.
' Even so. A little teenage rebellion is only healthy Fionna, she should be expecting it.' Fionna thought about this for a moment then aquiesced. She was sixteen, she was old enough to make her own decisions, especially around boys. And Cake had agreed with that whether she liked it or not by giving her the book, she had all the information, and it's not like Cake could expect her not to go out and... investigate. That's just what she did with anything new. So If she didn't like the fact that Fionna was going to try something a little different, well she could go get stoned on some catnip. Not her problem.

' So now what?' She asked after she had jumped down the ladder. The skirt picked up the air and fluffed up around her hips, making her pause for a moment and smooth it down.
' Now... I think you should take me on an adventure.' Femme replied, turning into a wolf and giving Fionna a rather unsettling grin. She was unfazed though, desensitized because of Marshall's many and varied 'scary' faces.
' Really? Why?'
' Because, Fionna. I still don't know all that much about you, so I have no idea what exactly about you makes Marshall like you. Or what about you makes you like him as more than just bed fodder. Not that you could like someone like that anyways, seeing as you're totally inexperienced.' Fionna was getting fed up with Femme's constant insulting (even if it was correct) comments on her lack of experience and decided to give her what for. Femme noted with surprise the pose Fionna unconsciously adopted, sticking out her hip and tilting her head to the side in an obviously confrontational but also undeniably sassy manner.
' I'm not totally inexperienced, thank you very much. Just 'cause I've never had sex doesn't mean I didn't do stuff with my last boyfriend.' Femme sighed and turned back into a person, sitting on the arm of Marshall's couch and leaning on her hand with a bored expression.
' Did you ever touch his cock?' Fionna blinked at her and blushed violently, taken off guard by her blunt question.
' N-no. No! I couldn't anyways, he was the prince of the Fire Kingdom. I mean, just yesterday I could only kiss him because it was raini-' Femme frowned at her and raised a hand, cutting her off.
' Wait, wait. I thought you said this was an ex-boyfriend.' Fionna knitted her fingers together and rocked back and forth on her heels, looking down at the ground.
' Well yeah, But I hadn't seen him for a year and a half, and I missed him. It was just y'know, for old time's sake. And because I was frustrated about what Marsha- Actually, what he did means that I'm actually more experienced then you give me credit for!' Fionna said triumphantly, folding her arms and grinning smugly at the shapeshifter, who only appeared mildly interested.
' Yeah yeah, he tied you up and tore off your clothes. Big whoop.'
' That's not all he did.' Femme raised an eyebrow at her, and Fionna suddenly realised that she was bragging about something that she wasn't even sure if she had wanted to happen. At least not as quickly as it had.

' Actually wait, forget I said anything.'
' No no, you started, now you have to tell me.' Femme replied, leaning forward with a glint of mischief appearing in her eyes.
' Uh...'
' Oh come on.' Fionna looked down at the ground again then sat on the floor with an ungainly thump and crossed her legs, holding on to her ankles.
' He uhm... He put his mouth on m-my boobs and... lower.' She admitted after a few seconds, becoming more and more anxious as Femme failed to she couldn't take it anymore, she looked up and found Femme in the midst of a silent laughing fit, greatly confusing her.
' W-what's so funny?'
' No... No wonder you c-called me... a perverted creep! Oh, that's just too funny.' She giggled, shaking her head. Noticing Fionna's complete lack of comprehension, Femme wiped away a faux tear and adopted a business-like manner.
' Look honey, what I'm saying is Marshall used to be a lot smoother than that with girls he likes. He'd cajole and coax and court until they were the ones breaking into his bedroom. I never would've guessed he'd meet a girl who he had to have so badly he would jump her without her permission. He's acting completely out of character from the clinically sexy bad-boy attitude he puts up. It's formulaic, measured y'know. Something about you has made him throw that shit out a second story window, you're messing with his judgement. He's always been impulsive, but I don't think he's ever been this risky with his feelings for the sake of poontang.' Femme mused out loud, before looking down at Fionna and winking conspiratorially.
' I think you an' me might not have as much work to do as I thought. Maybe I should just teach you what to do when he's using that box of stuff on ya. I've been around the block, I'll keep you safe, honey.' Fionna blinked at her, still somewhat shocked by the assertion that Marshall wasn't just being a horny bastard or an ass. That he might actually find her sexy already, and he wasn't playing with her for the sake of it.
That he might like her back, really truly.

Author's note: Y'know, I was actually intending to make this chapter another two thousand words long, flashing abck to Marshall 'cause some big stuff is about to happen with him, but then I realised that that would make this single chapter almost as long as one of of my oneshots, and I thought hmm, Naaah. This is a good place to end it. I have drawn up What Fionna's new outfit looks like, and I really like it. Once I've coloured it I'll upload it too my Deviantart and put a link in the bottom of the next chapter. I might also draw up Femme, just so you guys can see what she looks like. Gumball will be making an appearance soon too, because as I've hinted, he and femme have history and I wanna play around with it. So, obviously I've already got two thousand words worth of the next chapter, so you guy shouldn't be waiting too long, but like I said, big stuff is gonna happen So it may take a while for me to get it juuuust right. Nothing but the best for you lovelies ;3
