'This is it.' Finn stood at the foot of Marceline's porch. He'd been standing motionless for some time now, just staring at the wooden door. He didn't know why exactly he was delaying himself. Maybe some part of him still hoped he'd be able to talk himself back into reason given enough time. But that chance had long since passed. The temperature had lowered dramatically with the onset of the storm, and a cold gust blow into the cave. Finn brought his hands to his forearms and rubbed, attempting to recover a little heat through friction.

Dejectedly, he began to step up to the door. There was no hope of convincing himself to turn back, and Finn was sick of waiting out in the cold. Bringing his fist up, he'd barely tapped on the door when it creaked open just a few inches. Finn felt a mild sense of confusion, but decided to press forward regardless. He slowly pushed on the door and stepped inside. The interior was surprisingly dimly lit. Candles provided what little light was available, but largely only served to accentuate the shadows of the home. In a less ominous context, he supposed the whole setup could have almost been regarded as romantic. As it was, however, Finn felt this only added an additional eerie sensation to his ordeal.

What struck him as most questionable was not the lights, but Marceline's absence. In almost every other case, she'd always met him at the door. This time, he'd not actually been invited inside, and he couldn't see or hear any other indication that she was even home. Finn was almost starting to think that the resident vampire might not even be home at all. But as he made his way towards the center of the room, he heard the door softly close behind him. He turned about to find Marceline standing just by the door. Shadows danced across her form, masking much of her finer features. But even in the dark light, her expression was clear as she gazed upon him. A wicked grin played across her face and her eyes burned with a look he'd not seen on many other people. It was triumph, but not of the sort he'd shown when he'd defeat a monster and save a village. No, that was the look the monster would have when the hero failed, when the village was burning and the people lay it its' mercy.

Without even bothering to turn, she locked the door. Lifting off from the ground, she began to float over to close the already short gap between her and Finn. She came right upon him, mere inches from his face. She hovered relatively close to his eye level, but kept herself raised slightly above him, just enough that he was forced to gaze up to meet her eyes. Captivating as they were, how could he look anywhere but directly into them?

"I knew you would come." She breathed into his face.

"…Yeah."

There was not much else Finn could bring himself to say. He didn't have to, his presence was a clear indication that he'd given up, that Marceline had won. He didn't have to say it aloud to make it any more obvious.

Never losing her grin, she drifted past Finn and towards the ladder. Finn turned in place, never letting her escape his range of vision. She began to levitate higher, making it obvious that Finn was to follow her to the second level. So he walked over and gripped the handholds, dragging himself to the upper floor. The light was no better upstairs, perhaps even darker if anything. Marceline sat on the edge of her bed, silently beckoning him over.

Finn acknowledged her silent order, and made his way over, taking a seat right beside her on the bed. He kept his eyes down, as though by doing so he could somehow ignore whatever it was Marceline planned to do to him. He knew he was powerless to stop it, but a good deal of fear still gripped him in this knowledge.

He felt Marceline shift beside him and then felt her hand under his chin, guiding him to look up slightly. She held a fizzy drink before him in her opposite hand, gesturing it towards him.

"Drink this." She said quietly.

Reluctantly, he reached out and accepted the cup. 'She probably drugged this.' He thought, recalling similar instances in their past. Regardless of his concerns, he had little other choice but to relent. He downed the entire drink in a single, drawn out sip. The last few drops hadn't even left the cup when he started to feel the effects. What he felt, though, was not exactly what he'd expected. Finn didn't have a perfectly clear memory of how exactly he felt when under Marceline's influence in the past, but he could tell that something was definitely different this time. He didn't feel tired, necessarily, but very calm, relaxed in both body and mind. Maybe she had used a different sort of drug this time? Or maybe he'd just become used to the drugs. The glass slipped from his hand, but clattered harmlessly to the floor.

"Why don't you come back here?" He suddenly heard Marceline speak behind him.

He realized that she had at some point moved away from him, and turned around to find her kneeling towards the head of her bed, facing him. He blinked hard a few times and rubbed his eyes, feeling something was strange about what he was seeing. He was staring right at Marceline, but there was something slightly off about her. He couldn't actually determine any major difference in her appearance as opposed to just a few moments prior, but he was certain that something had changed.

For some reason, he had become hyper aware of Marceline's actual figure. For the first time that night, he realized just how strikingly beautiful she appeared. Her attire was an ensemble he'd become quite familiar with over the years, and one of the earliest he could remember her wearing. She was just dressed in her old strapless black dress and pale purple leggings, yet there were several things he noticed that made him question how he could have possibly missed these in the past.

Simple little things, like how the purple belt around her torso lifted and accentuated her breasts, just barely covered as they were by the saw-toothed fabric. Or how the hem of her dress fell just a few inches above the tops of her stockings, leaving a tempting amount of thigh exposed to him. And it wasn't simply in how provocatively she was dressed. Her jet black hair fell luxuriously down her back, fanning out behind her on the bed and looking so soft and inviting, like a lovely blanket. Her pale skin, always so cool to the touch, captured the flickering shadows that almost made her flesh itself look alive. Her razor fangs, well, just the sight of those brought intense feelings to Finn's mind.

And then there were her eyes. Deep crimson punctuated by bottomless back holes. Finn could tell just from gazing into them that those eyes held the sum of everything Marceline felt for him. And more importantly, they reflected everything that she had had poured into his own mind. Every idea of love, lust, submission and obedience that swam around in his head was ratified, amplified, and revitalized.

"Well?" She said in an almost too playful tone.

Realizing that he'd been just staring at her for some time, he shook his head to remove the errant thoughts and then shifted his whole body towards the bed. H crawled forward over the soft quilt until he was kneeling just before Marceline. He wasn't entirely sure what Marceline would do to him. Would she berate and torture him for his attempted resistance, or just wipe everything out of his mind, leave his body a puppet to toy with at her own luxury?

He saw her reach a hand out towards him, and couldn't help but shut his eyes. If something terrible really was about to happen to him, he would rather not see it coming. But he was surprised to find that instead of a hostile strike or painfully invasive order, he felt only a gentle hand caressing his cheek. He cautioned cracking open an eye, catching a glance of the woman lovingly rubbing his face. There was no malice, no ill intent evident about her, but a truly sympathetic smile, of all things.

"I understand you're frightened. I realize how much anger, how much hate you must've felt towards me for what I've done." She spoke so softly, completely sincere.

Marceline's hand left his cheek, but only so she could close the gap between them, wrapping Finn in a tight embrace. He felt a shiver go down his spine, but not because of fear this time. Marceline rested her chin on his shoulder, her mouth just be his ear.

"But you know, I didn't do anything just so I could hurt you. You'll see, I did this so that you'd love me, because I can give you the happiest life possible. I'm the only thing you'll ever need. You'll understand soon, and you won't disagree."

Finn could barely even pick up her words, quiet as they were. Even so, he found he really couldn't bring himself to disagree with her. He could feel the truth behind them. Even if it was just the truth Marceline herself had fabricated, it was the truth he had to accept, he wanted to accept.

Finn trembled in Marceline's arms, eliciting a series of soothing sounds and coos from her. 'I guess, this really isn't so bad…' There was little point in trying to rationalize anger towards her at this point. Her embrace was soft and warm, her voice soothed and comforted his fevered mind. 'What does it matter that she did this to me?' Regardless of their origin, Finn's feelings were clear; he needed Marceline. 'Even if it's not my choice, she makes me happy.' There was no longer anything keeping Finn from acting on those feelings.

Finn's arms slowly crept forward, reaching out for their object of desire, desperate to reciprocate the love which she had already shown him. That one motion was all the more sign Marceline needed. There was no longer any doubt of Finn's thoughts, he'd truly and fully accepted her dictum. He was ready to fully accept her.

Marceline pulled back a bit from him, enough to look back into his face. She just had to confirm what she already knew, and his eyes betrayed the complete acceptance he'd just come to terms with. Now was the time when she would finally lay her permanent claim on him. 'And give Finn what he deserves.' Marceline pressed forward, capturing Finn in a deep kiss, which he was now more than happy to accept.

All too quickly though, Marceline had pulled away, relinquishing her grip on Finn in the process. Her departure seemed to come as a shock to the young man, who looked almost distraught at her actions, obviously desperate for further contact. But Marceline had no intention of leaving Finn wanting; not now, and not ever again. Still, she could help but chuckle at his display, only further proof of how essential she'd become to him. To ease him back, she put a finger up to his lips, urging his silence.

"I think it's high time I give you a reward for your good behavior." She said deviously.

Lifting herself to the air, she again took Finn by the shoulders, but more forceful this time. In a not entirely gentle motion, she had shifted Finn across her bed so he now sat with his back against the headboard. He did not have a solid idea of her intentions, but courteously allowed himself to be manipulated.

Marceline delicately lowered herself to the bed, laying between Finn's knees and staring up at him with her cruelly playful smile. He could only return with a nervous smile of his own. Lowering her head, she brought her attention to a wholly different part of his anatomy. Confidant to the point of near zealousness, she moved her hands to grab at his zipper.

Finn's eyes grew wide as he suddenly realized just what Marceline had in thought for him. Blood rushed to his face, as much from excitement as embarrassment, as hazy memories of half-forgotten previous encounters resurfaced. He remembered how he'd been used, like a tool, but also remembered how incredible it had felt; how indescribably pleasurable and wicked those ordeals had been.

A soft 'vwooop' sounded before he felt Marceline's hand slowly creep into his shorts. His heart began to pump wildly while he felt her smooth digits take hold of him. By the time she released him from the confines of his clothing he was already fully prepared for her.

Although Marceline could keep a much more measured façade, in truth she may have been even more excited than Finn. She may have had him at her mercy in previous engagements, but what was about to happen today was in a completely different league. Now she didn't just have his body to act as a mindless slave to her lust; now Finn was an active and willing participant, ready to prove with his own power just how deeply he was devoted to her.

And she knew, the sweeter she made the pot, the farther Finn would fall into his obsession. Not willing to delay herself any further, she dipped her head forward, serpentine tongue hanging out of her mouth, and licked him, just across the very tip.

'Heeeehhh.' Finn let out a prolonged gasp as the strangely alien yet almost familiar feeling fleetingly sparked him.

Marceline had barely made a move and already Finn's senses felt overloaded. For her part, Marceline was rather pleased with his response. 'Heh. I wonder just how long he'll last when he's fully conscious.' Eager to tease him further, her tongue flicked back out, reaching inhumanly far. Displaying monstrous dexterity, she coiled her tongue down and along his entire length, capturing him like a python constricting her prey.

Finn groaned even louder at her action. He felt her tongue begin to writhe and squirm against him. The sensation was one she'd enacted against his own tongue before, but feeling those familiar sensations against a much more sensitive zone was practically surreal. Warmth began to well up in him at the pit of his stomach. And then he felt her envelope him completely. Her lips slid down nearly to his base and her tongue continued its ministrations, now enhanced by the new, much warmer environment. Finn took in sharp breath, not daring to break his silence for fear of embarrassing himself any further.

He had to force his neck to crane down so he might get a look at the temptress that was servicing him. Her head bobbed and swayed ever so slightly, and her great curtain of hair concealed nearly all of her body. Utterly caught up in the inescapably pleasurable sensations, Finn found his hands moving up to Marceline's head, gently entwining her locks in his fingers. This only seemed to spur her on, as she quickened her pace, making vast strokes across the entirety of his member, all the while continuing to lavish her tongue against it.

Finn's breaths became heavier and more labored, his only way of keeping from himself from groaning like an animal, and keeping at least a tiny shred of his dignity left. 'I can't believe… how good this feels…'

Marceline released her seal on him, deftly bringing her hand up to continue to stroke him onwards while her tongue continued its' work. As she carried on, Finn felt the pressure beginning to build, knowing he would soon reach his peak. 'Should've… broken down… a long time ago.' He made no attempt to communicate to Marceline, warn her of his impending climax. He was as drunk on pleasure as he was on the chemical cocktail coursing through his veins.

But she was as aware of the inevitable as Finn himself was. She was well aware of the subtle actions, having grown quite accustomed to his body language in her time spent with his mindless self. She made no attempt to stop or slow herself, instead taking him back into her mouth. This was actually her first time performing such an action, this being the first occasion where Finn's feelings actually mattered as much as her own. But she was quite eager to get a real taste if him for the first time, and intended to carry things through to the end.

"Marceline!" Finn grunted as his grip on her tightened.

She felt him release into her eagerly awaiting oral cavity, ecstatic in the knowledge that this was a product of her handiwork. She graciously swallowed everything he'd given her, not necessarily because it gave her any physical pleasure, but because it further cemented the idea that everything that was Finn's belonged to her. She felt him release his grip on her head, and rose to meet back with him. She found him leaning back against the wall, eyes closed and trying to catch his breath. She let out another low, humming laugh.

"Well, that was certainly fun, but…"

She began before leaning back up to Finn's level. Once he felt her breath gently breaking against his face he opened his eyes to find her own staring back and that same, devilish grin. She began to trace a finger up the front of his shirt, enough force behind her claw to leave a notable scratch on the fabric.

"I think it's time you returned the favor."

"Anything." He returned, breathlessly.

"That's what I wanted to hear."

Marceline circled her arms about him and once more Finn felt himself being dragged through the air. This time, though, it was she who landed against the bed and he who lay atop her. This was not an angle he'd been privy to know before, and he had to say, it really provided an interesting outlook.

Being able to look down at the soft body lying under him, whose eyes were eager with a clear lust for him, filled him with a new sense of… duty. He realized, he wasn't just concerned with his own well-being any more. He wasn't just here so Marceline would make him feel better, he desired just as much to reciprocate those feelings, return the vast feelings she'd inundated him with.

'Now just… uh… where to start?' Despite all that, he was embarrassed to admit he had no idea on how to lead. It must have shown on his face, as Marceline couldn't help a good-natured roll of her eyes.

"I said, return the favor." She said, emphasizing the latter half.

As she spoke, her hands reached up to Finn's head, pressing down on his scalp from above the luscious roots of his hair. As she began to lightly encourage him down towards the lower part of her body, a spark of enlightenment went off in Finn's head. His face went even redder as he realized what she meant for him to do; to return the favor, in as literal a sense as possible.

Once his face was level with the hem of her skirt, he reflexively began to reach his arms up. Half his mind told his body to move with rushed enthusiasm, the other half tried to paralyze him with anxiety. The mix resulted in jittery, uncertain movements. Trembling hands gripped the edges of her dress. He slowly began to inch the fabric up her body, revealing more and more of her tempting skin. His eyes snapped up to her face to ensure that this was in fact what he was to be doing. Marceline just lay with her head back and eyes closed. With no obvious objection, he had little reason to suspect he was going about things incorrectly.

Focusing back on his work, he hiked the dress up the remaining distance to rest on her abdomen, just beneath her belly-button. A renewed sense of embarrassment hit him as he was faced with his lover's now nearly exposed nethers. A thin pair of silken purple panties was all that protected Marceline from the elements, and those did little to hide anything. A small but easily distinguishable wet spot had formed on the front, revealing the sheer, aroused state that she had been in for some time now.

Despite his total lack of experience (voluntary experience, anyway), Finn was not as ignorant as most thought him to be. Growing up with an older brother like Jake did leave him with quite a bit of, admittedly unasked for, knowledge regarding the fairer sex. He understood what the liquid was evidence of, and had at least a basic idea on what he was supposed to do. That knowledge, unfortunately, didn't exactly inspire a great amount of confidence in himself.

But frightened as he was of making a mistake, he was more afraid of making a fool of himself by doing nothing. 'Here goes something… I guess.' Breaking through that thin mental barrier, Finn again reached his fingers up, curling them around Marceline's waist. Gripping the light fabric, he slowly began to pull down. He had to bring his whole body back, Marceline assisting his efforts by raising her legs up and back. Now he knelt between her bent legs, her delicates in hand, watching for the first time as she fully exposed herself to him.

Despite his recent release, Finn felt himself began to harden again. He could smell her scent growing headier, more oppressive. Like a pheromone, it just seemed to flick a switch in the basest part of his brain. He was growing restless, the longer he just remained in her presence the more he wanted to just throw himself at her, let his most animalistic self take over. But overshadowing that was an even stronger presence in his mind, the certainty that he belonged to Marceline, and it was her happiness that came before his own.

Certain in that regard, he finally worked up the nerve to lower himself back down before Marceline. His head just beside her nearly-dripping opening, he breathed her scent in deeply, feeling his head swim. He had no real direction, but her request still rang sweetly in his head. 'Return the favor.' With no better ideas, he figured he'd just reciprocate her actions as closely as he possibly could.

He stuck his tongue out, much shorter and more blunt than Marceline's, but thicker too. Closing the last small gap, her pressed his tongue at the base of her slit and trailed up along its' length, as slowly as he could manage. Marceline let out a sharp breath. She'd been waiting for this moment for so long, going over every possible detail in her head a hundred times over, but nothing could prepare her for the real, physical feeling of having her long-desired lover worship her in such an intimate way.

Finn heard her gasp and her body reacted in kind, almost seeming to clench up. He liked the effect he had on her, even so immediately. Bravado rising, he set about recreating that feeling for her a thousand fold. He pressed himself as close to her as he physically could, his lips connecting with hers in an entirely new breed of kiss. He poked his tongue back out, feeling Marceline begin to give as the muscle pressed forward into her.

That definitely had a pleasing effect on her, as Finn's actions forced a squeal from her. But he was certain that sound only signaled the pleasure that she was feeling, and was vindicated when she reached down and buried her fingers in his hair, just as he had done when the roles were reversed.

Much more confidant in his actions, he began to wiggle his tongue about inside of Marceline. He may have lacked for experience, but he certainly seemed to make up for that in sheer eagerness, and Marceline wasn't about to complain. Finn was finding more and more quickly that just listening to his natural instincts seemed to be the best thing to do. He felt his arms reaching up to grip Marceline's thighs, giving him a better support.

For her part, Marceline never stopped encouraging Finn, panting and moaning all the while Finn was servicing her. Whenever he hit an especially sweet spot, he was rewarded with an extra scream or sudden jolt of her body. And Finn seemed perfectly pleased to be providing her with his service, never once relenting in his lovely assault. But despite his efforts and utter enthusiasm, Marceline realized that this simply would not provide her the stimulation she needed to reach her climax. She had been hoping to just let Finn work things out on his own but it seemed…

"AHHH!" Her thoughts her interrupted by an intense burst of pleasure.

Finn had been happily lavishing her when he noticed a small bump near the top of her opening. When he reached that spot, Marceline let out the loudest shriek she'd released so far.

"Finn…Keep… Doing tha…AHHH!" She didn't even have to finish her sentence.

Finn had already realized that the spot he'd just hit was even more sensitive than the rest of her. He didn't need her to tell him twice to focus his attention there. Encouraged to double his efforts, he began to swirl his tongue all around her small bud, alternating that between placing light kisses atop her.

Marceline looked like she was going crazy, thrashing about and crying out in pleasure. She began to softly mewl out Finn's name between rapturous shrieks. Hearing her acknowledge him, Finn started to get even more inspired. He wanted so desperately to bring her to the same peak that she herself had shown him, and suddenly got an idea on what he could do to get her there.

He removed his left arm from Marceline's leg so he could bring his hand close up by his face. Bringing his mouth away for just a second, he gently pressed the pad of his finger on the small button he'd been paying such rapt attention to. Marceline felt the sudden change, and was hopeful that Finn was about to follow through with what she'd had in mind. He began to softly rub his finger up and down the length of her slit. The pressure wasn't quite as intense as what Marceline had just grown accustomed to, but that was not truly the purpose of Finn's action. Once he felt the digit had been sufficiently lubricated, he brought it down to her base, and then slowly began to insert it as far as he could.

"Yessss, Finnnn…" She hissed out, signaling her approval of his action.

Pleased with himself, Finn retuned his attention to the small bud that seemed to act as a direct line to Marceline's nervous system. Pressing his tongue back against her, he began to slowly scrape along her inner walls with his finger. Marceline all but lit up, squirming perpetually beneath Finn. Her grip on his hair became almost painfully tight, but Finn gladly bore through it. She could feel how close she was, and felt herself losing control of her body. Her legs shot out, wrapping around Finn's head and pulling him as close to her as was physically possible. He was slightly caught off guard, but never ceased his actions, continuing to lick and rub against her most sensitive spots.

Finally, everything burst forth from Marceline at once. She let out an ear-piecing shriek. Almost fortunately for Finn, her legs squeezed tightly around his head, muffling her sounds and trapping him in place. He felt her lower body go stiff beneath him as her opening quivered ceaselessly around his tongue and finger. She tugged viciously at his hair, but he'd never do anything to dissuade her, despite his own discomfort.

After several seconds, her body went limp. The only sounds that filled the room were her ragged breaths. As her legs fell from his shoulders, Finn raised himself up on his hands to get a look at her. Her chest was heaving greatly, further embellishing her breasts, which seemed only seconds away from bursting out from behind the fabric of her dress that now seemed wholly insufficient for containing them.

Raising up higher, he got a good look at her face. She continued to breath harshly, but wore a bright smile that seemed far more sincere than all her others had been this night. Finn couldn't decide if it was actually her demeanor that'd changed or if it was just his perception of her growing more and more skewed. Either way made little difference to Finn now, and he quickly dismissed the though upon once more meeting her eyes. Half lidded red orbs seemed to almost glow at this point, and he could feel them boring into his head, displaying the intense gratitude she was feeling.

He couldn't stop himself from crawling back up her body. As soon as he had come close enough, Marceline's arms snatched him lighting fast, bringing his face down to her own so she could give him heated kiss. Finn relinquished himself to her control, happily obliging her and enjoying her demonic tongue as it ravished his own.

Marceline felt herself welling up with such love for Finn, she couldn't possibly articulate it in words. It was much easier, and much more fun to show him her feelings this way. He'd more than shown how devoted he'd become, an even now she felt certain he wouldn't ever regress from his current state, no matter what she did to him. But still, she needed one last display from him, one last piece of proof that he would always be hers.

Finn felt more than a modicum of pride for having provided Marceline with such intense feelings. He knew she'd established a permanent place in his mind, and he felt as though he was being rewarded for his good behavior as fuzzy and warm feelings began to course throughout his head. This was the reason he'd come back to her, that feeling that everything was right in his life that he could only receive from making her happy.

Eventually he began to note a shift in gravity. Opening his eyes, he found that Marceline had once again twisted them in space. Now she lay atop him on the bed, but she never once let their mouths unlock. Finally, she drew away from him, scraping her fangs lightly against his tongue as it vacated her mouth.

"You did good Finn." She said softly.

It was funny, she felt like she was extoling a pet for performing a trick, offering him the proverbial 'good boy.' But then, there really wasn't a more appropriate analogy. Finn had surrendered himself to her, establishing the notion that they were not on equal terms. He really was closer to a pet than a partner. But that was what she had truly desired all along, to take Finn for her own in a way that would ensure he'd never be able to leave her. And it wasn't like he was being hurt by this. Frankly, he was coming to terms with his fate much faster than she'd been anticipating. And the longer her stayed with her, the more content he'd become. She knew in her heart it was the right thing, for both of them. Her motives might have been largely selfish, but she knew in the end things would work out for the best for Finn as well. At least this way, she could personally assure that.

"But you're not quite done."

"Whatever you want." Finn spoke, a notable hint of excitement present behind his voice.

Marceline was ecstatic to hear him speak, hear how he was rapidly falling to his desire for her. Settling herself down on Finn, another sign of his clear cooperation became evident as it brushed across her thigh.

"You know what I want." Her voice had grown quite low.

Finn did indeed understand what she was asking of him. He felt like his mind was overloading, but unlike previous similar experiences, it was not a painful turmoil that was plaguing him. It simply felt like many things at once were jockeying for position at the forefront of his mind. Part of him just wanted to lay back and accept whatever pleasure Marceline would gift him, but a stronger part of his warped mind began to argue that that would be selfish. He was starting to believe more and more strongly that he was here for Marceline's sake, not his own. Whatever good befell him was just a side effect he wouldn't mind enjoying, but it was Marceline's happiness that truly mattered. So he came to a decision. 'I'll show her right now how much she means. I'll prove I won't just be a burden.'

"As you wish." He spoke with an odd inflection that Marceline wasn't expecting.

Before she had a chance to even cast him a questioning glance, he had reached his hands up and under her arms, reaching around her back to grip at her shoulders. Forcefully, he brought her back down to him, initiating a kiss with her for the first time. Marceline was caught completely off guard, not expecting that Finn would dare to act so bold after everything she'd done to him. In mere moments, though, she'd simply melted into his embrace, feeling too good to argue against this breach of contract.

Just as she was settling down into a comfortable mental state, she felt Finn begin to lift abruptly beneath her. Her mouth otherwise occupied, a muffled cry of bewilderment was the only objection she could make as Finn threw himself completely forward bringing her back with him. All of the sudden, she was on the bottom with Finn forcefully pressing against her. She'd grown so accustomed to him acting so mindlessly obedient, she'd forgotten just how powerful he was, that he was in fact a hero. Or used to be, anyway.

Finn pulled away from Marceline, finding she appeared totally flushed. He chuckled inwardly, 'kinda nice to not be the embarrassed one for a change.' Once Marceline had composed herself enough, she did her best to put a scowl on her face, but the effect was lessened with her face appearing so bright.

"Finn! How dare you…" She attempted to vocalize her anger, but was silenced by Finn once more sealing her lips with his own.

Pulling away rather quickly, Finn loomed over her and tried to make as sincere an apologetic a smile as he could manage.

"Sorry Marceline, but please…I, I just wanted to show you how I feel, how much you matter to me. So please…" With a hopeful smile and desperately pleading eyes, he gently took hold of her hands in his own.

"Let me prove it. Let me prove that I want… I need to be with you."

Despite all the cockiness he'd shown in his actions, now he looked to be all but begging for her understanding in his reasons. Marceline might've almost found the whole thing comical if not for the utter sincerity she could feel practically emanating from him. She could tell he really did mean what he said. Everything he did, everything he'd ever do from now on would be without concern for his own thought and being. Everything he'd ever do would be for her sake.

"Finn…" She said, forcing Finn's eyes wide in fear and anticipation.

"Just shut up and fuck me already."

Her blunt demeanor shocked Finn a bit, but he was far away from being dissuaded. A few seconds later, he'd brushed off the momentary hesitation and let out a small laugh. 'I'd better enjoy this now. I'm not sure if I'll ever get her to say that again.' He looked back into her eyes, and could see them growing impatient, needy even.

Finn knew he could not put this off any longer, as much for his own sake as Marceline's. 'I just hope I don't screw this up.' Eager as he was, he didn't really have any true experience to work off of, only half-memories and several of Jake's ramblings whose credibility should've been immediately called into question.

But his performance anxiety immediately began to dissipate as soon as he felt Marceline shift beneath him, bringing herself closer to him. He felt her presence close in on him, sending a shiver up from his waist and throughout his torso. He was certain now, this wouldn't require any extensive knowledge or talent. Nothing but his basest senses were necessary for the act they were about to commit.

His body moved of its own will, trained much better than his mind had been. Closing the insignificant gap, he ground his length along the outer lining of Marceline's opening. Feeling Finn slide across her most sensitive region sent a flush of warmth coursing through Marceline, who groaned in equal parts joy and frustration. The anticipation was becoming too much for her to handle. He continued to make several sliding motions, back and forth atop her, issuing almost pained groans from both of them. Even though Finn was as growing as impatient as his partner, he was determined to draw things out for as long as possible, make the experience as blissful for them both as possible. It was the vampire who cracked first.

"Enough teasing Finn! Just do it already!" She demanded of him.

Finn had sunk so far into the pure physicality of the situation he couldn't even be sure if her words had really reached him or if his body had just driven forward by its own decision. Regardless, as soon as Marceline had cried out for him, Finn reared back until he stood poised just before her, and then plunged into her fully. He groaned through clenched teeth as the evil woman beneath him let out a cry of heavenly anguish.

They both lay motionless for several moments, shuddering quietly in uncontested happiness. But before too long, the sensations that each felt began to dull, drawing the desire of both to rekindle those feelings. Finn slowly began to pull himself back, scraping along Marceline's inner walls. Just before he'd left her completely, he stopped himself. He drove himself back into her, not quite as forcefully as his initial entry. This time, he wanted to drag things out, create as much friction as he could.

As Finn continued his movements became more measured as well as more confidant. Marceline began to gyrate her own hips, doing her best to try and match Finn's own motion. Eventually the two were moving in rapturous harmony. When one would speed up the other would quicken to match their pace, and when one would slow the other would restrain themselves to keep the frequency. Pleasant moans and quiet whimpers filled the room, serving to spur each participant to push their lover to new heights.

Finn's brain was in sweet chaos. Neurons fired off in rapid succession, stretching to the very peak of their limits as they worked strenuously to interpret the onset of feelings emanating from his body. All the while the veritable slurry of chemicals that had collected in his head continued to fry all rational thought and any sense of his past self. Above everything else was the deep psychological scar that Marceline had carved into his mind, ever driving him to do whatever he could to please her. And the higher he saw her climb into ecstasy, the greater reward his twisted mind provided.

Marceline's experience was no less intense, but not for the same reasons. Like Finn, it wasn't just the physicality of the moment that kept her mind edging closer and closer to nirvana, but the psychological implications behind the act. Everything she'd worked to achieve, put so much time, effort and hope into, was all coming to fruition right now, in this very moment. Finn, the man she'd desired so incessantly to possess, had fallen right into her clutches, exactly in the way she wished. She'd claimed him as more than a partner, he was her possession. She'd forced into his mind an unnegotiable, inarguable, uncontested obsession of her. She'd taken his mind and molded it like clay, and he'd seen fit to thank her and BEG for her to continue. Finn would never be the same person because of her, would never desire the company of another living soul. And that thought, that she had taken absolute control of his heart, mind and soul; that was her drug.

Lost in the act, the two continued to collide together in harmonious delight. Carnal desire drove their bodies in a mutual, nearly mindless rut that had steadily become more and more wild and frenzied. As their physical selves strived to sate themselves, each was lost in the hazy void of their respective minds, relishing in complacency, each having their own reason for feeling so self-gratuitous.

All at once, everything came to a blinding head. The vampire and the young man were drawn out of their inward bliss and brought back to the full reality in the wake of their mutually approaching climaxes. Finn's senses returned to him, and he gazed down to the gray woman who was panting and heaving beneath him. She opened her eyes, her brilliant red eyes that he found so beautiful, so inescapably captivating. Seeing her gaze back at him he could sense the desire, the obsession she felt for him that mirrored his own. That silent acknowledgement finally tipped the scale for Finn.

He let out an unrestrained cry as he felt his essence empty into Marceline. Feeling Finn release himself was the slight push that she needed to fall over her own precipice. She met his cry with one of her own. Her legs wrapped around his lower back to ensure they never separated while her hands went to his back. Her claws etched vicious markings into his back, tearing through fabric and flesh just as easily; just one more mark that denoted Finn as hers.

Neither spoke immediately, leaving their elevated breathing the only sound filling the room. Marceline was perfectly content to allow this silence to continue and bask in her lingering feelings. The peace that always followed was one of the most soothing times she could ever enjoy, relishing the feelings as her body cooled from its feverish high and the endorphins slowly left her mind in a pleasantly mild stupor.

Finn could've hardly made any attempt at action even if he'd wanted too. The overwhelming force that had gripped his mind in the midst of their passion had left it virtually fried. So mentally fatigued was he that he'd all but lost track of his own body. He could no more tell where any part of him was than he could tell where Mars was at that moment. The only thing he could register was the soft sounds still emanating from Marceline, and the faint sensation of the softness of her body against his own.

Both lay complacent together, Finn still atop Marceline, his head having fallen atop her pillowy chest. As his finer senses began to return to him, he became aware of Marceline ideally twirling her fingers though his golden hair, now somewhat matted with sweat. 'Man… she really… likes to… play … with my hair…' The clearer his thoughts became, the better he found he was able to make senses of what he was feeling. And he realized that he felt happy; perfectly happy. He felt no regret for having left his life behind for Marceline. If this was how he would feel all the time, then he could be perfectly content knowing nothing but her kindness for the rest of his life; or far more likely, the rest of her life. He fully understood that nothing he felt was truly a product of his own will, but he didn't care. Marceline could keep him drugged or hypnotized or in chains as long as she cared to, and he wouldn't ever be happier in any other situation.

The rest of his life was clear to him, and regardless of the reason why, he couldn't be happier. Forcing as much weight as he could to his side, he just managed to roll off of Marceline, not wishing to discomfort her any further (even though that had never been the case). At his absence, Marceline rolled onto her own side so that she could meet back with his gaze. As their eyes met again in dichotomous union, Marceline graced Finn with her sinfully sweet grin. He returned with a truly gracious smile.

"So now you understand? You belong to me for the long haul." She spoke in tone that matched her smile.

Even though she needed no answer, Finn was still more than happy to oblige her, as he always would be.

"Perfect."
