Work Text:

** takes place right after Marceline poofed her vampire servants**
“I have to talk to her, this- this just isn't her.” Simon whispered, pulling his face back from the hole when he and Fionna had been watching Marcy’s cruel treatment of her servants from.

“Dude? Are you crazy? She just killed those guys with her bare hands! We have a job to do.” Fionna shoved a few garbos around the hole and motioned for them to leave and finish their work.

“And I'll be right behind you, I promise. She’s not going to hurt me.” In the few seconds that Fionna was not by his side Simon had stashed his bag of bombs and crawled through the hole.

“Shit” Fionna watched where he had been for a few moments before deciding that she still had to finish this for Bonnie. She quickly left, leaving garbos in her wake.

“Ma-Marceline?” Simon announced himself from the hole in the wall, careful to not startle the girl.

“Wha-? You!” Marceline flipped around from the mirror to be greeted by the old man she’d seen Bonnie and what was left of her crew (heh) with, crawling through her doorway. In a matter of seconds she’d snatched him from the wall by his collar and held him high in the air, gasping and kicking his feet at the sudden capture.

“What do you think you're doing?” She growled, pressing her face close to his so he could feel her breathe against him. She should just suck his soul and drain him right now, this worm had already crossed the line by daring to enter her room without her permission, but something about him just made her wary of actually hurting him. Marceline could demolish this willowy, malnourished man with a snap of her finger, but is he worth the energy?

“I-I-I just wanted to ta-talk to you! Pl-Please!” Simon's face was going a bit red from the exertion of keeping himself up enough to keep his airway open in her grasp. He couldn't last much longer, this might have been a bad idea. Marceline did not respond to him immediately. Instead she just stared at him as he struggled.

He wasn't begging to be spared or fighting her grip or anything really beyond taking this. Hell, if she kept him like this he’d probably just let himself die without ever even trying to put a hand on her. It was… endearing.

“Hm.” She threw him halfway across the room onto her daybed. He struggled to get himself situated in all the pillows and blankets and plush that littered the whole bed, just another way this weirdo was establishing himself as unworthy. Cant even regain composition quickly, what could have possessed him to come in here?

“So who are you?” Marceline stopped watching him and returned to her mirror, fiddling with her head piece to make sure it was still pinned correctly.
“I am Simon. Uh, I know this is going to be hard to believe, sweetheart,” She looked back at him in the mirror, such an affectionate term for him to be using on a monster. “I am from a- another world, dimension actually. “ He eyed the floor, what had he wanted to say to her? What could he possibly say that could fix whatever this vampire king had done to his own sweet girl? He drew a deep breath in.

“I took care of you.” Marceline turned around and looked at him sitting on the edge of her bed.
“I made sure you were safe and loved and as…uh, I guess, as healthy as i could… with the whole world ending-” He frowned at that. He hasn't really talked about Marceline’s childhood with Marceline before, it was too sore of a spot. He’d made too many mistakes.

“Well, I've never seen you before.” Simon chuckled softly at her tone, so defiant, so bitter, so far removed from the nuanced and polite Marceline he’d gotten the pleasure of getting to really know in his own dimension.

“Yes,uh, I believe I died before I could find you- More than likely vampires, heh. You know in my world you became a great vampire hunter! Slaying all of Vampire King's inner circle and then him too! From what I hear it was, uh , epic.” He finally looked at her face, She’d meandered closer while he’d been talking and looked thoroughly unamused with him and his vampire hunter Marcy.

“So what? You want me to hear your little story and change my ways?” Marceline was now right before him, glaring down at the audacious small man. “Just give up my life and turn my back on everyone because some dude feels bad?” Truth be told, Yeah. He did want to convert her to good, he wanted to touch her heart and make her realize this was bad.

“Uh, well- I- I don't know, dear… I guess I just want you to know you are good regardless of what's happened.” Simon scratched at the back of his head, this wasn't going the way he wanted. This Marceline wasn't as receptive as he believed she would be. Above him he couldn’t hear anything, had she left? Grown tired of him and flew out to kill all his friends?

“The Fuck Do You Know About Me?” In an instant she was on him, pressing him into the bed with her body and clawing at his face with her talons. It felt like she was touching his bones with her nails and could feel beads of blood rolling down from when she had his face held. She had him held so firmly he couldn't even move his face to the side enough to see her face, let along respond to her question.

“I am not some fragile child. I am dangerous and ruthless and I do not need reassurance from some pathetic old man.” He felt spit hit his face, indicating she had her face close up to his again.

“Mar-cy-” Simon struggled out, trying to grab at her wrists to gently move her hands from his face. She dug her nails in more, drawing more blood and filling her senses with the metallic smell. Before she really knew what she was doing she was licking a thick stripe up his face, cleaning some of the blood off him and egging herself on with the toy that had delivered itself to her. Pressing a little harder onto his face, she sat up and took her hands off his face once she was fully up. Beneath her Simon was trembling, a mixture of all sorts of contradicting emotions and fears flooding his brain making everything hard for him at this exact moment.

He was going to die to this girl, he could feel it. All he’d done since he came in here was make her mad at him and now she had him bleeding and restrained, two things you definitely don't want to be around a vampire.

“You are a bad caretaker-” Marceline grabbed his plush cheeks in one hand, forcing him to look at her. The fear, the dishevelment, the blood. It's been quite some time since she’d had something this~ delicious~ in her bed. Probably since she took Bonnie's eye all those years ago.

“ I am- I am, uh, I am like your Dad?” Simon sniffled and stared into her eyes, had Marcy always been scary like this? With the way her large, black eyes bore down into him he had to admit that he could see how this Marceline could be seen as a monster. The smile that broke across her face when he called himself her dad only added to his fear.

“Yeah? My Dad, huh?” Tears kept slipping out the corners of his eyes and joining the blood and spit on his face. So this man fancied himself her father? Well she already had a dad, buuuttt she’d always wanted to try a Daddy~ Marceline rolled her hips down over his a little before sitting squarely over his lap, feeling a slight bulge. He looked panicked, with his arms curled into his chest as a way to guard himself.

“What kind of Dad gets a hard on from his daughter?” She took her hand from his face, leaving a couple gashes as she pulled back, and grabbed both of his wrists on his chest.

“ I-I am not-” Simon didn't even get to finish before she pressed her hips to his again, this time slowly grinding against whatever she could feel down there. For a vampire, she was very warm between her legs. Even though all the layers he could feel how hot she ran and it made him want to sob. This wasn't how it was supposed to go.He was supposed to come in and have a beautiful conversation with her about how wonderful she was and she would become the good girl he knew she was.

“Yes, you are! Yes, you are! “ She giggled and humped him though his pants more, each stroke causing him to harden despite his best efforts of not. It’d been too long since he’d been in a situation even near sexual, he felt like he had no control over his lower half. Simon bit his lip to stop any more of the whines and sobs from escaping him and hopefully dissuade Marceline's toying of him.

“Hey.” She patted his face a few times making his scratches burn. “Make noises again, Daddy. I liked them.” Marcy tried to bounce a couple times on the tent between his legs, but he didnt not budge, staying silent and glaring at her.

“Even when I give you the opportunity to be a good father, you just can’t perform. Pity. “ She growled at him before letting his wrists go with a slight shove to show disapproval. Simon would have gotten to breathe a sigh of relief and regain some control of the situation if Marceline had not immediately settled down in between his legs that were hanging off the side of the bed. She started to undo his belt and make her way down to his skin which caused him to sit up quickly.

“No! No, No, NO!” Simon tried to push back at her hands, he couldn't kick at her out of fear he’d hurt her nor could he stand without having to push push her. His little pulls and pushes did virtually nothing to her progress and she just ignored his babbles of no. Eventually she got everything unbuckled and buttoned enough to grab his pants and underwear at his hip and jerk them down, tugging them far enough down to act as a restraint on his legs so he no longer even had the option to kick at her.

“Whoa… You must have some weird feelings towards your Marcy, huh?” His erection had sprang free and was openly leaking down its own length.

“No! I would never-” Tears were running down his face at full force now causing the blood to flow with them and stain the collar of the new shirt Winter King had just given him. So much for looking nice on this adventure. She watched his pitiful display for a moment, he didn't seem to really have a high tolerance for stress and approached everything with this idealistic perspective- falsely believing things will just go his way. That level of tenderness just made her wetter, she was the predator and he was the prey.

Marceline licked up the trail of pre along the underside of his cock. She’d never had this type of human fluid before, it was intoxicating. A musk flavor, similar to how humans smelt, but also a heaviness, similar to the typical blood she drank. She needed more- and covered him with as much of her mouth as she could. Simon was still trying to stop his noises resulting in strangled sobs and whines while he curled his arms once again to his chest. He couldn't admit this felt good. He couldn't admit the reason this felt good wasn't because she was necessarily good at it, quite the opposite really- she was bad at it in the way one would imagine a teenager was bad at it.

She had no sense of pacing or depth. A truly shocking lack of rhythm for any dimensions Marceline, just going at him for the sake of. Simon made the mistake of looking down at her and promptly closed his eyes after. If it felt disorganized, it looked sloppy. She had spit and his fluids all over her face and hands, every time she moved either sticky strands stretched out and snapped under their own weight. A heat started to break out under his skin and he feared that this hack job of a blowjob was going to make his blow his load over Marceline.

He didn’t mean to release such a primal sound, but this was far too much. He’s going to cum on this Marceline's pretty, terrifying face and have to carry the mental weight of that action with him forever.

“Were you gonna cum?” Marceline laughed, pulling off him and leaving him covered in spit and fluids that felt like they froze the second she removed her mouth.

“No-I-Its-” Simon could even hear how weak and wet his voice sounded.

“I-its? Stop stuttering. You were really just going to cum and I’d get nothing? What a dude-” She rolled her eyes at his pitiful display of gasping for a response to her. He had nothing. That’s exactly what this loser was going to do to her.

“Move back on the bed.” She flicked the head of his cock before standing up between his legs. Simon didn't do anything but gape up at her more, still having a hard time catching up after all the emotional confusion he’d been through and the aborted orgasm. Everything was just muddled, it's like he wasn't even a participant in this.

“I said MOVE '' Marceline's face contorted into something more akin to a demon with sharp, snaggle teeth and large red eyes. He moved up on the bed, up amongst all her cutest plushies and soft blankets, as she took off the black overalls she had just had her subordinates put on her. Technically that was a waste of perfectly good vamp slaves, what with them being poofed and all, but she had a new type of subordinate now. One who seemed to be attached to her in a very deep and emotional way unlike the usually shallow and fear filled way her fathers servants were.She didn't bother taking off her top before climbing up on the bed with him, sitting just a little below his dried member.

“Okay- Li-listen to me, Marceline. This is bad. You are a good girl! I know you! I know you here and I know you back at home and you ARE good.” Simon had to try. He couldn't let himself be pulled into the concept of having such a lovely and forbidden teenage girl milk him in her cozy little twin bed. It was scandalous, it was wrong, it was indeed bad.

“I am just trying to be good for you~ isn't that what you like?” She lifted herself over his cock, stroking it lightly as she hovered above. “Good girls?” Time slowed down for Simon as he watched himself disappear into her slowly. She took each inch like it was the first, going excruciatingly slow till she was fully seated on him. She panted a little and dug her hands into the fabric right above where she was seated.

The stretch wasn't what she expected. When she’d had sex before she’d just had fingers in her, twisting and rubbing along her inside. This? This was so much more. This was carving space in her that she didn't know she could give. Reaching beyond what she thought was her end and rubbing what felt like the bottom of her stomach.

Simon just watched from below as her entire demeanor changed. Gone was all her bravado, her eyes were clenched tight and her hands dug into his vest. She, uh, she wasn't a virgin? Right? All that confidence lead him to believe that she did have a level of experience, but when compared to the skill level she displayed with her mouth and her current reaction to his modest at best size.

“Your, uh, you're doing a good job sweetheart~” He unclenched his hands from his chest and rubbed her shaking thighs. Maybe he didn't fully want this, maybe he did- that didn't seem to really matter to him when faced with Marceline feeling any discomfort.

“Ugh, st-stop doing that. I am forcing you, you should be crying.” She slapped at one of his hands, The sting of being penetrated fully for the first time starting to melt away.

“I am still crying, dear.” He smiled up at her when she looked at him. He was still crying and covered in blood, but had such a kind look on his face. No one looks at monsters like that and it made her insides twitch around him. Simon exhaled and let his head fall back into the pillows at her twitching. He’d put off enjoying her heat but now that she was adjusting he could enjoy the tight warmth that enveloped him.

Marceline huffed at him and started trying to set a pace on him. Lifting herself up and dropping back down in an unorganized fashion, attempting to get into rhythm and failing to maintain anything of note. Simon, meanwhile, was in a type of heaven he thought he’d never get again.

As with the blowjob, she was not exactly good at this. But she had all the charm in the world, naively bouncing and whining on him with what appeared to be no set goal in mind. He closed his eyes and just stayed in the moment. The plush bed swallowing him, the slick girl wrapped around him leaking kitten noises, the feel of her unblemished thighs under his aged hands.

When he opened his eyes he could see the frustration on her face. She wasn't hitting her own spots as well as she was his. Heh, he doubted she even knew what her spots really were.

“Do you want me on top?” Simon ran his hands past her thighs and up her hips, dipping under her loose blouse.

“ You're not even crying anymore!” She snarled at him, her face entirely lavender from exertion. She was doing this right, this was how male and female sex works. How dare he imply she needs help!

“Okay, okay. Uh, sorry for not crying anymore…” He chuckled a little as she let out several irritated grunts.

“What about if I just-” Simon changed the grip on her that he had. Digging his thumbs into her hips bone and changing her riding from a deep up and down to shallower grind and pull.

“Oh-” Her whole body jerked forward when he hit something in her, she just barely put her arms out to keep herself from laying on him. Now, her eyes closed and her head sagged, everytime he moved her hips he managed to get that one spot in her again and again and again. Each time more coos and whines she should be ashamed of leaving her mouth and dripping over him, being met with words of encouragement from him that she couldn't make out with all the lightning coursing through her currently.

Marceline nearly choked when he started thrusting up to meet her hips on the down swing. It was getting to be too much. Her head was swimming and her legs were starting to feel like jelly.

“Marcy~ “ He sighed “Oh, O-oh, My little girl~” Her walls were beginning to flutter and grip him tighter making it hard to hold off on peaking in her. This situation was beyond fucked up, he knew that. He also knew that he was fucked up, meeting her hips with his and openly enjoying her like this, and she was fucked up too, shamelessly mounting him in order to play at some power fantasy she clearly had. But you know what would be really really bad fucked up? If he came first and left her to have to quickly catch up on his deflating dick. He pulled and pushed into her at a quicker rate, desperate now to finish her off.

“Dadddyyy~” Marceline practically screamed in a tone he’d never heard her use before in any dimension and dropped to his chest, burying her face in the crumbled and bloodstained fabric of his dressing shirt, while her insides convulsed around him. Simon had no reason anymore not to wrap his arms around her twitching body and fuck up in to her convulsing pussy to reach his own peak. In fact he’d spilled himself in her before she’d even truly come down from her own orgasm.

They stayed attached for a moment, both breathing heavy and full caught up in their own thoughts. For Simon it was the obvious post nut clarity, the feelings that he had defiled his little girl contrasting with the feelings of never having been so content with a sexual partner making him want to never have to leave this moment and deal with the actuality of either school of thought. Marceline, on the other hand, needed to leave and leave now.

She could feel, what she assumed, the fluid she had tasted earlier deep inside her and leaking out between them. It made her feel sticky. And even worse it made her feel claimed in a heartfelt and intimate way she hadn't expected from this. She had wanted to scare this man and destroy him, making him tremble before her and sob for her to stop, stop, stop!

Instead he, uh, he took care of her? He showed her how to move her hips without making her feel like he was controlling her, he made her see stars behind her eyelids and let her lap up his blood. Marceline jerked up, ripping herself from his arms wrapped around her and looked down at him. Wide eyes, blood with little canals cut through it from the tears she caused and a little smile. What a fucking moron she’d just bedded.

She chuckled at him and leaned down to kiss him. The action must have shocked him since he took a moment to meet her kiss back, but he did return the kiss. It was just like the rest of him, soft and tailored for her. Marceline pulled back and kept her face close to his.

“ If I see you again I’ll kill you” She breathed against his mouth before snatching one last kiss and getting off him. He didn't have time to respond, his brain was still too fuzzy and by the time he’d so much as sat up she was redressed in her overalls and flying out of the room via the hole he had entered from.
