Chapter Text
The party at the Candy Palace was insane. The music was so loud Fionna could practically feel the vibrations in the air as the speakers Prince Gumball had rigged up blasted out the music the band was playing. Fionna appreciated the old world tech souped up with science as she slipped inside the crowd of writhing candy bodies. The overstimulation and noise momentarily overwhelmed her but she soon found herself becoming infected with the crowd’s energy.
“You doing okay, Fi-Baby?” Cake yelled, which was necessary to be heard over the music. Fionna smiled at her and gave two thumbs up.
“Yeah,” Fionna yelled back. Cake looked like she wanted to say something else but was distracted, her fur poking on end and pupils dilating as she noticed the gray mane of Lord Monochromicorn in the distance. “Go for it!” she yelled, giving Cake a push. Cake winked at her before stretching out and disappearing into the crowd.
Fionna had been away adventuring the westernmost edges of the wasteland far past the Wizard City and Goblin Kingdom for the last year. She had been following rumors she had heard about a powerful magical artifact, something that shouldn’t exist in this universe. Being away from her home with Cake and truly alone for the first time in her life had been oddly peaceful and not something she would have thought she’d enjoy so much.
She hadn’t called Prince Gumball to let him know she was back in town and fill him in about her solo adventures, she had been looking forward to surprising him with her presence tonight. She could spy him on a balcony dancing away with a tight-knit group of candy citizens. The Biennial Gumball Ball was always an elaborate affair, and perhaps she had grown a little used to her time of solitude, because she couldn’t remember it ever being so loud before.
She saw a punch table near an open window and made a beeline for it, narrowly dodging a group of wildly dancing breakfast people and almost slipping in the puddle of excretions left from some slime citizens on her way. She ladeled herself a cup of cherry red punch into a crystal glass with a shaking hand, gulping it down thirstily. It was a bit quieter here due to the open window and she could again hear her own thoughts.
“Hey Fi, aren’t you a sight these sore demon eyes,” a smooth voice said directly in her ear. She whipped her head around so fast the bunny ears on her hat hit the invisible face that had to be hovering just inches from her own. “Pfft,” Marshall Lee said as a bunny ear hit him in the mouth and he visualized next to her. “Good to see you, too,” he said with a smirk.
“Oh my glob, sorry Marshall,” Fionna said, her face immediately heating up. She hadn’t seen Marshall Lee in years, since he had decided to take a more active role in helping his mom rule the Nightosphere as their residential Vampire King. “Why were you invisible?” she asked.
Marshall threw his arms behind his head and floated lazily, turning his body slightly to peer up at the balcony where Prince Gumball was still vigorously dancing.
“You two aren’t fighting again, are you?” Fionna asked. “What did you do?”
“It’s not me, that wad up there always has a problem,” Marshall said casually. “He even dances like he has a stick up his ass, just look at him.”
“If you hate him so much, why are you sneaking into his party all stealth-like?” Fionna asked with an eyebrow raised. Marshall held up a brown glass bottle, giving Fionna a smile that accentuated his prominent canines.
“I couldn’t miss the opportunity to spike the punch and see how his royal highness acts when his little Gumball Ball delves into drunken candy debauchery.”
“You want to ruin his ball? That’s not very nice of you, Marshall Lee,” Fionna scolded. Marshall scoffed, taking a moment to feign the appearance of being wounded at her words. He grabbed at his heart and twisted in the air to face her, blinking once to make his eyes turn into demonic black rings with glowing red pupils.
“I’m evil, baby, in case you’ve forgotten,” Marshall hissed at her, his snake’s tongue wiggling in her direction. Fionna smooshed his face away with her open palm, laughing.
“I’ve missed you,” she said. He blinked again and his eyes returned to normal.
“What did you miss most? My hot bod or my devil-may-care personality?” he asked. Fionna laughed nervously, not wanting to answer his question.
Marshall Lee had wormed his way into her horniest thoughts and fantasies since she had been a young teen, and now that she was a woman in her early twenties she was finding him positively irresistible.
Not like I have a lot of humanesque options, she thought, sparing a glance at the nearest candy citizen, Mr. Lollipop Man.
“You always flirted with me before, I thought now that I’ve grown up you’d finally drop it,” she said, trying and failing to keep her tone casual. She knew he was just messing with her, he was a flirty, creepy vampire. He had always been this way. He was just trying to make her uncomfortable, she knew that.
“No, girl, quite the opposite,” he said smoothly. “I have to say I’m glad you haven’t ditched the thigh-high stockings, they still make guest appearances in my favorite dreams.” Fionna averted her eyes, her face heating up as she felt an involuntary throb of pleasure between her legs at his words. He had never said anything quite that explicit to her before. Marshall floated closer, whispering in her ear. “I can smell it, you know."
“W-what?” Fionna said, trying to take a step back, suddenly self-conscious.
“Your arousal, Fionna, and it smells so good,” he said, punctuating his words with a sniff behind her ear. She was sweating. “I can pick up on your pheromones, you know. You can’t hide it from me.”
“I-I’m going to punch you in your stupid face for that,” she said, reverting back to her old standby, punch first and ask questions later.
“I like pain,” he said. She seriously considered running from him, she was going to say or do something to make herself look like a total idiot in front of her long-time crush. “Listen, Fi, I’m not trying to scare you off, but I don’t know how to be any more clear about this to you. I want your thighs wrapped around my face.” She felt her heart skip a beat, her senses short-circuiting.
“I-I,” she stuttered out, trying to think of a snarky response and failing. He allowed himself a cocky grin before his tone turned serious.
“Look,” he said, reaching out and tucking a length of her blonde hair back into her bunny hat where it had escaped its confines. “Let’s get out of here, come back with me to my place. Not to fuck, but the offer is on the table. I can see you seem uncomfortable with all the noise here, and it’s quiet there. We can catch up. It’ll be nice, like old times.”
“You want to spend your night just talking with me?” she asked. She felt another throb between her legs at his very explicit offer, but she was still too nervous to truly let herself believe the crazy things he was saying. She had never even let herself pretend he wanted her in that way, and it would take a bit more time for it to truly sink in.
“There’s nothing I want more. Even if we don’t do it, spending time just talking to you is definitely better than spiking the punch and pissing off Prince BG.” Fionna hesitated before Marshall held out his hand, a knowing look on his face. “Look, girl, I already know you’re going to say yes, just c’mon.”
Fionna took his hand and he pulled her off her feet and through the open window by the punch table. Marshall transformed himself into a demonic bat, Fionna soaring through the air to saddle his back. She threw her head back and laughed openly, her wide eyes filled with the night’s stars and she soared through the cool air. She pulled her bunny hat off and let the rushing air run through her blonde hair, the strands flowing behind her in the wind.
Before she knew it they were going through the open mouth of the dark cave and to the familiar two-story structure of Marshall Lee’s house. Fionna jumped off his back in a single motion, coming down on the craggy ground in a braced position.
She stood up and dusted herself off, turning to see Marshall back in his normal form, floating up behind her. She went to put her bunny hat back on but he stopped her, holding the hand that held her hat gently.
“Leave it off,” he said. “I like seeing your hair.”
“Okay,” she said, running a hand through her long hair to smooth it out.
She expected Marshall to make a raunchy comment but instead he floated ahead, grabbing the door handle and pulling the door open for her with an innocent smile. He gestured with his hand, inviting her inside. Fionna walked inside and sat on his uncomfortable couch. She felt a bit nervous and wasn’t sure what to say but then Marshall’s zombie poodle Schwabl scurried up excitedly to greet her.
“Hey there girl,” Fionna said, sinking her hands into the fluffy black fur and scratching behind her ears.
“Here,” Marshall said, sitting beside her. It struck Fionna as odd Marshall was physically sitting beside her instead of floating above the couch as he usually did. She acutely noticed their thighs were practically touching. He had two cups filled with red liquid in his hands, and she accepted one.
“Thanks, Marshall,” she said, taking a sip from the cup. She grimaced when she detected the strong bite of alcohol. Marshall snickered, biting at his cup and draining out the red from it.
“Is that okay? I didn’t want the liquor I brought to Prince BG’s ball to go to waste.” Fionna took another hesitant sip.
“I just wasn’t expecting it, but it’s fine,” she said. “I’ve kinda developed a taste for Cake’s wine over the years. Can you even get drunk, Marshall?”
“Only with booze from the Nightosphere, which thankfully this is,” he said. “Tell me about what you’ve been up to, Fionna.”
Fionna thought it would be awkward here alone with Marshall Lee but honestly it wasn’t. They only stopped talking in the small spans of time needed for him to bring their cups back to the kitchen to be refilled. He was really easy to talk to, and surprisingly caring although he would never admit it. He told her about the Nightosphere and a few notable events she had missed while she was away. She told him about traveling the wastelands in the west in search of a rumor about an Enchiridion from another universe ending up in Aaa.
“What’s the problem with another Enchiridion?” Marshall asked her.
“Well, you know they can be used to create portals into the multiverse. We got rid of this universe’s Lich but a Lich, or something worse, from another universe could crawl through if a portal is opened. If an Enchiridion is out there in Aaa I can’t sleep at night comfortably unless I know where it is so it can be guarded. It’s all I can think about. I… I’ve been having a really hard time, I’m scared we’re in danger, but there’s nothing I can punch. I’m scared all the time. I’m just scared of my thoughts, I guess. What kind of hero is afraid of their own thoughts?” The drink was making her words loose, she was admitting more than she meant to and she’d be very embarrassed if she was in a clearer state of mind.
“You sound a bit obsessed,” Marshall observed, his tone not unkind. “This doesn’t sound healthy, have you talked to Cake about this?”
“W-well, I mean, she knows I’m going through some biz and I asked her for some space and she accepted that I needed that.” Marshall shifted closer, casually throwing an arm around her shoulders. She couldn’t help but jerk in surprise at the motion, but he didn’t make a comment about it.
“Maybe space isn’t what you need. It’s okay to tell other people your fears,” he said. She squirmed a little, and he raised an eyebrow at her. “Is this okay?” he asked, giving her shoulders a little squeeze.
“Y-yeah, it’s okay,” she said. It was actually much more than okay, and if he had been telling the truth about being able to smell her arousal earlier his nose should be absolutely on fire right now. Uncharacteristically, however, he was keeping the flirting to a minimum. “I guess I do feel better after talking about it,” she said, which was the truth.
“You know you can talk to me anytime,” he said. “I care about you, Fionna.”
“I care about you too, Marshall. We should hang out more, when you’re not in the Nightosphere, that is.” He groaned, leaning in closer to her, their bodies sealed together. Fionna’s heart hammered against her chest at the contact.
“Don’t bring up that hellscape, the last thing I want to do is think about that place right now.” Fionna felt gripped by a sudden bravery, probably thanks to the alcohol.
“What do you want to do right now, Marshall?” she asked.
“I don’t know, do you want me to put on a movie? I have Heat Signature or,” he was silenced as Fionna closed the distance between their faces, gently pressing her lips against his.
Her lips moved against his unmoving ones for a few seconds before he responded with a jolt, grabbing her and kissing back with enthusiasm. Their lips moved together seamlessly, and she felt like a fire was burning under her skin as her body responded to his mouth. He sucked her bottom lip into his mouth and nibbled on it and she couldn’t hold back a moan.
“Fucking finally,” he mumbled against her lips when they parted for air, keeping their foreheads pressed together.
“Finally?” Fionna questioned, the word being lost in Marshall’s mouth as he pressed his lips against hers again. He licked his way into her mouth, moving his tongue against hers. When she shyly pressed her tongue into his mouth in return a moment later he sucked on it greedily, humming with contentment.
“I’ve wanted you forever,” he literally growled into her mouth. His hands began roaming as he spoke. They went to innocent places only at first, such as up and down the sides of her arms and the length of her back, but they were growing bolder by the second, and she was struggling to keep up.
“Really?” Fionna asked, feeling dazed, and Marshall chuckled lowly, working his mouth from her lips to down the corner of her mouth and lower still. He settled on the crook of her neck, licking and sucking, placing sloppy open-mouthed kisses wherever he could reach. Her skin burned like fire under his touch and she froze up under the unfamiliar sensation.
“You’ve gotta be kidding me, Fi, I didn’t think I could have been any clearer,” he said between the kisses he was lavishing on her. She slowly slid down to a lying position on the couch as he placed more of his weight on her, his body settling intimately in between her parted legs.
“Running around like a tease in these stockings,” he groaned, his hand finding her thigh and harshly slapping the flesh there before digging in his fingers. Fionna sharply drew in a breath as her thigh stung, this all beginning to feel like a bit too much too soon.
“M-Marshall,” she said hesitantly. He ground his hips down into the warmth between her legs, his other hand snaking under her shirt to find her bra, squeezing her covered breast.
“Don’t feel shy to say my name, baby, I’ll have you screaming it in a minute,” he said into her neck as she squirmed uncomfortably, feeling like she was on sensory overload.
“Can I actually have a minute,” she gasped, finding herself hungry for air. His mouth and hands froze and his head shot up, a horrified expression on his face. Her face flooded with embarrassment and she averted his eyes.
“Shit, do you not want this, Fionna?” he asked, propping himself up on his elbows to get some distance between their bodies. His black hair was messed up from where her hand had been tangled in it. She hadn’t even realized she had done that. “I got carried away, I didn’t mean crawl on top of you like this,” he said, looking down at their position as if he hadn’t even been conscious of what he was doing.
“It’s okay,” Fionna said quickly. “I liked what you were doing.” Marshall completely peeled himself off her, scooting back several inches away from her on the couch, looking down at her with an uncomfortable expression.
“I, uh, had more to drink than I realized,” he said awkwardly, speaking in an oddly vulnerable tone she had never heard him use before. As he was usually the pillar of confidence, it was very strange for her to hear him sound uncomfortable in any way. He surveyed the reddened marks he had left on her neck and thigh as he spoke, frowning.
“You didn’t do anything I didn’t want, it was just a bit, um, intense,” Fionna said. “I want to do this, I’ve just never done it before.” Marshall openly groaned, taking his head in his hands.
“Glob, I’ve fucked up,” he said, which hurt her feelings.
“You didn’t actually want me?” she asked, tears forming behind her eyes, which she hastily tried to blink away. He looked up in surprise.
“No, I want you so badly it hurts,” he said. He looked like he was going to reach out a consoling hand but stopped himself. “I didn’t know you were still a virgin, and you’re drunk.”
“Well, a human in Aaa doesn’t have a lot of options,” Fionna retorted, feeling suddenly embarrassed and defensive about her virginity. “And it doesn’t matter if I’ve had a few drinks, I wanted you even when I was sober.” Actually, she had wanted him far, far longer than that, for about as long as she could remember, but she wasn't brave enough to say all of that.
“It wouldn’t be right,” he said weakly, and she laughed.
“What happened to you being bad?” she asked, and he rolled his eyes.
“It’s different with you, I actually really like you, I don’t want to mess this up like I mess up everything else.”
“What if I want you to mess me up?” she asked, her tone innocent. Marshall groaned, squeezing his eyes shut.
“That isn’t funny,” he said. “Don’t tempt me, I only have so much resolve.”
“I mean it, Marshall Lee. I want you,” she said. “Just, just go a bit slower, maybe.” He ran a hand through his hair, considering her.
“I don’t know how to be gentle,” he admitted. “But I can try.”
“I’m a tough girl,” she said. “I can take it.”
A heartbeat later he was on her again, kissing her mouth deeply. He seemed to be exhibiting some restraint this time, as his hips and hands remained still while their lips moved together. It was... nice. She liked it.
“I, uh, I’d like to take you up to my room,” he said when the kiss broke. “Your first time should be in a bed. That’s the normal way.”
“Because everything is so normal about my life,” Fionna laughed, but accepted his hand when he offered it to help pull her off the couch. She followed him up to his room, not feeling nervous or scared of what was coming next, perhaps just a bit giddy with anticipation.
“You know,” Marshall began as he shut the hatch to his bedroom behind her. “We don’t have to like, actually fuck. We can, uh, just make out or cuddle or some shit if that’s what you want.”
Fionna smiled, choosing not to reply. His words weren't exactly polite, but she knew he was just trying to ensure she was comfortable, and she appreciated it. Instead of responding she pulled off her shirt and kicked off her skirt as she climbed onto his bed in just her bra, panties, and stockings. She pulled up a leg to start tugging off a stocking but Marshall stopped her with a strong hand around her wrist.
“The stockings stay on,” he growled, his pupils having turned a demonic shade of red.
She blinked up at him, feeling a throb of pleasure between her legs as she looked into those red eyes. Glob, how had she never noticed how hot they were? She nodded, her mouth having gone dry. He blinked a few times, his eyes returning to normal, and after a few seconds she began to feel a bit uncomfortable with the way he was staring at her.
“Is something wrong?” she asked, crossing her arms around her abdomen. Marshall looked taken aback.
“No,” he said quickly, shaking his head quickly as if he were trying to snap out of a trance. “I just never thought I’d get lucky enough to see you like this. Damn you’re hot. Can I take off your bra? I’ve always wanted to see your tits.”
“Oh, um, yeah,” Fionna said, biting her lip. He reached behind her for her bra clasp but hesitated upon seeing this.
“You can say no,” he said.
“I want this, I just, um, feel a bit exposed,” she said, glancing at him. “In comparison.” He looked down at his own body, looking surprised to see he was still fully dressed.
“Oh glob, shit, sorry,” he said, shrugging off his shirt and throwing it into a corner of the room. He unfastened his jeans and kicked them off, leaving himself clothed in just his tenting boxers. “Is this better?”
“Yes,” she said, gazing down at his lean, toned frame. He reached behind her and unclasped her bra, freeing her breasts. He went to reach for them but paused. “Can I?” he asked. Fionna nodded, blushing furiously.
His strong hands found her breasts and he groped them carefully, trying to hold back his urge to flip her over and nail her into the mattress. His thumbs brushed over her pert nipples and she shivered.
“I liked that,” she said.
He gave her a wicked smile and repeated the motion, his thumbs repeatedly rubbing over the sensitive nubs of her nipples. He brought his fingers in and gave a gentle pinch, making her arch her back into his hands. The pleasure was building and pooling in her groin as he worked her and she began panting. They kissed a bit but he kept pulling away to gaze down at her with hungry eyes.
“You’re really sensitive,” Marshall said with a smirk as he watched her squirm.
“Yeah, well, I really, really like that,” Fionna all but moaned. He was kneading with one hand and had a sensitive nipple between the fingers of his other and was giving it a few teasing little tugs that were absolutely setting her body on fire. She allowed this a few more moments before bringing up a hand to brush his grabby hands away from her chest.
“Had enough of that, baby?”
“It got a bit too sensitive,” she explained. “Can I touch you, too?”
“Please do,” he said.
Fionna hesitantly brought her hands up to touch Marshall’s toned chest. He gave her a reassuring smile and she returned the expression shyly. She wrapped her arms around him and pulled him on top of her, lying back on his bed. She brought their lips together and closed her eyes, losing herself in the feeling of his lips moving against hers. Her hands roamed around his body, feeling the muscles of his back moving beneath his skin.
She slowly brought her hands to his front and rubbed his chest before slipping lower, hesitating at the downy hair sprouting below his belly button. He broke the kiss at that and smiled devilishly at her, his gleaming fangs doing something very, very hard to describe to her.
“Wanna see it?” Marshall asked, hooking a thumb into his waistband. Fionna nodded, watching with wide eyes as he pulled down his boxers and threw them into the same corner as his previously discarded clothes. His erection sprang free from its confines and she couldn’t keep her eyes off it.
She had always wanted to see one, and found that while she could admit it was big, it wasn't intimidatingly so. Even if it were, she wasn't going to back down. She was a fearless adventuress after all, but still she was relieved it appeared manageable. The swollen head of his length was reddened, but the rest was the same pale, undead shade as the rest of his skin. He had a patch of soft-looking dark hair at the base and there was a vein running across the top that caught her eye.
“You can touch it, if you want,” he said. She found that she wanted to touch it very much, in fact.
Her hand found the bulging vein and she traced it with a finger, causing him to hiss. His hips gave a little buck in her direction. Feeling more confident she grabbed around the base, pumping him with different speeds and gripping with different pressures, trying to see what he liked. His lips found hers again and he began slowly rocking his hips in rhythm to her moving hand.
She had to be doing something he liked because eventually he began making little moaning noises into her mouth as she jerked him. She found this was nearly as pleasurable to her as his hands on her had been. Knowing she was causing him to make these noises was driving her wild. She seemed to find a rhythm he really liked because Marshall broke the kiss with a low groan, burying his face into her hair as she stroked him, his hips bucking wildly.
“Fuck, Fi,” he said, grabbing her around the wrist to stop her. “Fucking let me eat you right now, please.” The desperate sound of his voice ignited a new passion in her. She gripped at his cock and tried to keep pumping him but he held her wrist firmly in place.
“Okay, yeah,” she said, letting go of his cock and spreading her legs a bit more. He had found his way between them again but was kneeling, his hard cock hovering several inches above her panty-covered sex.
He grabbed her panties at her hips and tore them off of her, the fabric straining and tearing before he got them off her ankles.
“Hey!” she said, indignant. She had really liked those! He didn’t respond, instead grabbing her thighs and roughly shoving them apart in his haste to get at her.
“Damn,” he said, gazing down at her on full display to him. “You’re really fucking wet.” He prodded at her experimentally with his thumb until it was coated in her wetness, and then he brought it to his mouth to taste. Fionna groaned, feeling far too turned on by this than she thought possible.
Marshall shoved his face between her legs at that, licking and sucking at her without warning. Fionna cried out at the unexpected pleasure, a hand finding the back of his head and burying in his hair. It was so intense and sudden it was borderline painful but she didn't want it to ever stop. She cried out as two of his fingers probed inside her, roughly stretching her open. She was no stranger to fingering herself so the sensation was not new to her but it somehow felt entirely different with Marshall’s fingers in comparison to her own.
“Oh my glob, Marshall,” she moaned, practically seeing stars. His fingers pumped in and out of her, setting a frenzied pace as he licked which suited her just fine. He found her most sensitive parts and lavished them with his tongue, lapping unrelenting over and over, building up her orgasm dangerously fast.
Fionna was a moaning, incomprehensible mess beneath him. One hand was balled up in the bed sheets and the other was pulling Marshall’s hair harder than she intended as his mouth closed up around her clit, sucking her like she was giving him life. She bucked her hips at this and cried out, practically kicking him off of her when the pleasure became too much to endure.
“Too good, Marshall, oh my glob,” she cried, her hand finding her oversensitive clit and covering it to keep him away from it. “Give me a second, that was just, too good,” she gasped. She hadn’t orgasmed yet but it was close. Her inner walls actually throbbed with the need to be filled under her hand and her mind felt fuzzy. She had never been so turned on in her life.
Marshall’s hand found his own cock and he began pumping it as he watched her recover from the onslaught to her senses he had just caused her.
“Are you ready for me to fuck you now, or do you want me to eat you a bit more first?” he asked with a cocky grin.
“Please,” she said. “How do you want me?”
“I’d love to see that ass of yours if you’d let me,” he said.
“Like this?” Fionna asked, turning onto her stomach and propping herself up on her knees.
“Fuck yeah, that's so hot,” he said, and he was behind her in a second, his cock pressed up against her ass. He rolled his hips a few times, rutting against her. His hands found the cheeks of her ass and he gripped them as he explored. He brought down a hand and spanked her, making her cry out. The flesh of her ass rippled in response and he watched it with a smile. “You like that, Fi?”
“Y-yeah, I do,” she admitted, her cheeks flushing.
“You ready for it?” he asked, his fingers snaking between her legs to tease at her clit a bit more just for fun.
“Yes,” Fionna said, burying her face into the mattress to moan loudly as he played between her legs with his talented fingers.
Marshall lined up the head of his length with the slit of her entrance and gave a little thrust. He found her wet and warm and unbelievably tight as he worked the head of his cock in. His hands were gripping her hips tightly and he threw his head back as he was overwhelmed with his first taste of the pleasure of being in her. It was so, so good, and he tried to shove more in but just couldn’t. She was too tight.
“Relax, Fi,” he said, rubbing her hips in what he hoped was a soothing motion as he pulled the head of his cock out and pushed back in, trying to fit in another inch or two.
He rocked his hips like this, trying to slowly work her open, his overzealous demon half screaming at him all the while to hold her down and forcibly take his pleasure out of her. He could ignore it for now, though. She was worth it. Eventually she relaxed, sliding down from her hands to her elbows as he buried himself completely inside her.
“Marshall, oh my glob,” Fionna panted, looking back to gaze at him with lust-clouded eyes. He met her gaze, his dark pupils blown with desire. He leaned forward, his chest sealing against her back as he captured her mouth in a kiss.
He pulled out completely and filled her again and again, her tight walls feeling like they were crushing him to death in the best way possible as he buried himself in them. His thrusts were getting rougher as he felt his orgasm building and he gripped her hips with more force than he intended, making her cry out. He forced his tongue into her mouth when she cried out and licked at her greedily. He let go of her hips and buried one hand in her hair and the other on her upper back, shoving her face down into the mattress to get a new angle.
“Marshall!” Fionna screamed, clawing at the sheets as he rammed into her. This new angle caused her so much pleasure her thighs shook and they almost gave out on her. He tugged at her hair so hard it hurt, and a wet slapping sound filled the air as his pelvis slammed against her ass with each thrust. It sounded obscene, and she loved it.
She felt absolutely exposed and vulnerable with her ass in the air, completely at his mercy as he pounded into her. She opened her eyes for a second to peek back and saw the blackened irises and reddened pupils of his demon’s eyes looking back at her. She closed her eyes quickly, shuddering with pleasure. She didn’t think he could stop himself at this point even if she asked him to, not that she ever wanted this to end.
The pressure was building in her lower abdomen and she knew this wouldn’t last much longer. He spanked her again, causing her to cry out into the mattress and pushing her over the brink. He swatted her a few more times punctuated by hard thrusts and her orgasm finally exploded around her, stronger and more vibrant than anything she had even been able to produce herself.
She swore she saw new colors as her walls contracted around his invading cock. Her toes curled and she had no idea what she was trying to say and if it was even comprehensible. Tears welled in her eyes from the sheer overwhelming onslaught of pleasure. She felt him ram into her a few more times before he suddenly pulled out, leaving her feeling frustratingly empty, immediately followed by the feeling of a hot wetness splattering across her ass and thighs.
Fionna actually did collapse at this, dropping down to lay on her belly on his bed, panting for breath with her hot, sweaty face buried in her arms. As she came down from the high of her orgasm she found herself feeling more content than ever before. The blissful calm after such a hot rush was surprisingly nice, and she wanted to do nothing more than linger in the feeling. After a few moments she felt Marshall grab the cheek of her bottom, his hand smearing in the mess he had left here.
“Fuck, Fi,” he said over her, his voice sounding pained. She felt him pawing at her hips and moving her hair to examine her back. She peeked an eye open, wondering what he was doing. “Fuck, fuck, I’m sorry,” he said, his fingers tracing lines on her back and shoulders. Her skin was tender where he touched.
“What for?” Fionna asked, turning to look at his horrified expression.
“You’re all, all marked up, shit,” he said. “I told you I don’t know how to be gentle, are you okay? You didn’t ask me to stop, did you? My, my demon-half took over for a second there at the end.” Fionna was almost too shocked to respond, did Marshall actually just stutter?
“No, it was perfect, Marshall,” she said quickly, trying to turn to face him. He groaned when he saw her front, her neck was covered in little hickies and bruises he had left.
“'Perfect?' Who fucks a virgin from the back like that? Ugh, I’m sorry Fi,” he said, gently rubbing his thumbs over the little marks and bruises he left on her as if they could be brushed away. “You should have had Prince Gumwad do this for you, he would have lit candles or some shit.” Fionna actually laughed, turning completely to face Marshall and grabbing him, pulling him in for a close embrace.
“Marshall Lee, I came home with you, not him,” she said, silencing him with a kiss. He returned the kiss, working his lips against hers in a way that was slowly becoming familiar. “You just gave me the best orgasm of my globbing life, quit ruining the moment with your apologies.”
“You’re right, I just wanted to make sure it was good for you, like I said, Fionna, I care about you,” he said. “We should, uh, do this again soon, if you want. No pressure.”
“I will definitely take you up on that,” she said.
He went silent, holding her close to him for several moments, her body fitting against his like a puzzle piece. It would be really easy for him to fall asleep like this. Time stretched on as they held each other and simply existed in the same space, breathing the same air and reveling in the lingering intimacy of the act. One of Fionna’s hands found his hair and was gently running her fingers through it while the other slowly rubbed up and down his back, soothing out tension he didn’t even know he had.
Marshall had never just stayed and cuddled someone like this after sex, and he found it surprisingly nice. He had always been a get in, get off, and get out kind of guy. Even the prior girlfriends he had had, none of them had been exactly cuddly. He had no idea what he had been missing, because this... this shit was good. Really good. So good he didn't want it to end, and yet all too soon Fionna shifted away, her eyes scanning the room for her discarded clothes.
“I should probably-” she began, but Marshall cut her off.
“Can you stay the night?” he asked quickly, internally cringing at the desperation of the request. “Y’know, if you wanted, it would be cool if you slept here, or whatever,” he added, trying to sound casual.
“Oh, yeah, that would be nice,” Fionna said. “Do you mind if I shower? I kinda feel sticky.”
“Only if I can join you,” Marshall said automatically. To his surprise, Fionna grinned broadly.
“Sure, Marshall. Sounds fun,” she said, pulling him in for a kiss. He kissed her back, feeling an odd sort of fluttering in his chest for the first time in his life.
