Marshall Lee plucked at the stings of his ax at random, not able to focus enough to produce any particular melody. He was trying hard to force himself to relax, to do things that should have been mindless to occupy his thoughts and energy.

He tried and failed to reproduce the intros to some of his favorite songs, his frustration growing as his fingers stumbled over the strings when he found himself thinking about the one thing he was not to be thinking about. He stopped playing abruptly, slamming shut his eyes and throwing his head back, letting out a noise of frustration at the ceiling.

He ran a hand through his dark hair, gripping the roots and pulling as if he could rip these thoughts out of his mind. He was no stranger to temptation. Living as a half-demon vampire was like existing in a constant state of longing for things he shouldn't have. Life's darker pleasures constantly called to him from the recesses of his mind, begging him to partake in things that horrified his human-half.

He was no stranger to squashing down thoughts and desires. He had suppressed things his whole life in order to be able to live in a society as a person and not as some monster who hunted in the shadows and hurt people for fun. He pulled at his hair harder, filled to the brim with self-loathing. Why was this suddenly so hard?

He remained like this for several moments before slowly relaxing his hand, his eyes drifting open to look at the ceiling. He blinked a few times, an odd sense of calm washing over him. He had control over his demon-half. He would feed into this one more time to get it out of his system and then it would never happen again. He could do this. He would be prepared this time. He took in a shaky breath, feeling equal parts giddy and disgusted about what he was about to indulge in.

He floated out of the door, turning invisible the moment he drifted through his doorway. It was overkill but he didn't want to risk being seen. As he flew through the night sky he tried to tell himself it was just normal curiosity. He told himself he was just bored, it was just something to do, but he knew it was all lies. What he was about to do was perverted and wrong. He felt a throb as that last thought caused blood to rush south.

He felt a nervous anticipation building as Fionna's treehouse came into sight. He hovered around it, wondering if he had been too late. Was she already asleep in her bed? He almost hoped she was, then he could just turn around and fly back home and chalk this night up to a bad idea. He saw the light on in the bathroom window and smiled.

He was ashamed to admit he knew her routine. This new obsession of his had started innocently enough, he hid in her treehouse invisible with the thought of popping out and scaring her. It wasn't until she had stumbled in completely exhausted and began stripping at the door did he realize what a golden opportunity this was. He did not reveal himself to her, instead watching with a dropped jaw as she found her way upstairs completely nude and hopped in the shower.

He had hovered above the curtain, watching as she washed her body with darkened eyes. He felt urges to do very bad things to her that he was nearly unable to suppress. He had almost done something unforgivable to her on that night. How close he had come to that point of no return had truly scared him. That fear had given him the will to tear his eyes from her body. He flew out of the bathroom window and all the way back home at top speed, thoroughly disgusted with himself.

That had been a week ago and he hadn't visited her since but glob had he wanted to. He had never wanted anything more than he wanted her in his whole life, even blood. Thoughts of her had dominated his fantasies, each imaginative scenario more vivid than the last.

He shivered as he remembered all of the ways he had imagined having her. He wanted her in all the ways it was possible for one person to want another. Well, almost all. One thing was for sure, he didn't want to force her. He didn't even do that in his fantasies, he wouldn't allow space for thinking about that in his mind. The thought appealed to his demon-half more than he would like to admit, but he didn't allow himself to linger on it.

He liked the thought of her wanting it just as much as he did. He could make her want it, he did have the power to compel, afterall. He grimaced, forcing that last thought out of his mind, hating himself for even thinking it. No, he didn't want her way that, either. Anyway, it didn't matter what he wanted. He wasn't going to actually do anything. He was just going to watch. That was an acceptable amount of dark indulgence in his mind. The thought of getting to see her naked body again tonight made his skin prickle.

The bathroom window was cracked open to allow the steam to disperse into the night's air. Marshall slipped inside unnoticed, his desire to see her again outweighing his hatred of himself. He hovered above the shower curtain, frowning when he saw she wasn't there. The water was running, steam filling the bathroom. Where was she?

His invisible, pointed ear perked as the bathroom door opened. A predatory smile spread on his lips as Fionna walked in, clad only in a towel, humming to herself. Her long, blonde hair was flowing down her shoulders and back and he wanted so badly to run his hands through it. Slowly, carefully, he floated close enough to smell her hair. He inhaled as deeply and silently as he could, savoring the moment. If he wasn't so caught up in the ecstasy of it he would have been horrified at what a total creep he was turning out to be.

He watched as she dropped the towel on the ground, her entire body on display for him. He swallowed a mouthful of saliva as he gazed at her breasts, the curve of her hips, the thickness of her thighs, and the swell of her bottom. He kept his hands in tight fists buried in his pockets so he wouldn't be tempted to touch her.

He watched as Fionna slipped behind the shower curtain, dousing her back and hair with the hot stream. She let out a little sigh, smiling to herself. Marshall watched the little beads of water that clung to her breasts with a single-minded focus, his jaw tight.

The little beads grew and connected to form a drop and he watched as it dribbled down her abdomen, past her navel, all the way down to her sex. He was completely aroused by now and trying to ignore the urge to grab himself and furiously jerk off over her. He was not going to do that here, there was no way he'd let himself fall that low. It was a line in his mind he would not cross.

He had to actively focus on not breathing hard or making any noises as she lathered up a washcloth and began washing herself. Soon she was covered in silky bubbles and he wanted so badly to put his hands all over her and feel as they glided over her soapy body. His hand drifted to the front of his jeans, where he could feel his erection through the layers of clothing.

He allowed himself to grip and release over the fabric in a slow rhythm, feeling a pulse of pleasure with each movement. He told himself this did not count as masturbation, which would have been creepy. This was just… keeping his hands busy so he didn't do anything stupid with them. He noticed a curious expression on Fionna's face he couldn't quite place. She looked a bit tense, maybe a little frustrated. He wondered vaguely what could have been troubling her as she rinsed the bubbles from her body.

She faced the shower stream and Marshall had to angle to get a better view, silently twisting in the air above her like a snake. After her body was clean her hands lingered on her breasts and for one fleeting, excited moment he thought she was going to begin touching herself. He gripped around the base of his cock, and paused, looking down in surprise. When had his hand found its way into his pants? He pulled it out quickly, feeling guilty. Her hands moved from her breasts to the tap and he frowned.

He watched in disappointment as Fionna turned off the water and stepped out of the shower. She bent over and picked up her towel giving him an amazing view of her bottom. When she did this he had to suppress an urge to grab her from behind and drag his tongue up the rounded cheek of her ass to collect the water droplets that had accumulated there. He grimaced and shook his head like a dog, wiling the thought to fall out of his head. A moment later she stood up, wrapping the towel around herself and stepping out of the steamy bathroom.

He floated behind her, watching as she walked into her room, leaving drips and wet little footprints in her wake. He had to make a split second decision to follow her into her room before the door shut, feeling like he was crossing another line as he did so but too enthralled by her to care. As Fionna began toweling herself off he began to second-guess his rash decision to follow her in here.

The sight of her body on full display to him as she rubbed the towel over her clean skin would have killed him had he been mortal. He had to admit to himself that he was now dangerously aroused. The temptation to grab her was too strong. He felt harder and more sexually frustrated than he had ever felt in his entire life. He glanced at her bedroom window, open and letting the fresh night's air inside. He had to leave now before he lost control of himself completely.

He drifted over to the window, pausing before he flew out of her room. He heard the gentle creak of springs behind him as Fionna laid down on her bed. One more look back wouldn't hurt, right? No, it was absolutely far past the time to leave, he never should have even come here in the first place. But, he was already here, he just wanted to look one last time. And, maybe touch. No, no touching. Absolutely not. He could make her forget. Fuck, he was such a damn creep! He didn't deserve to be alive. He grappled with himself about turning around, fighting waves of desire and revulsion and lust and guilt, a full-fledged internal war going on inside his head in those few moments. Then, suddenly, he heard his name and turned around.

"Marshall," Fionna sighed again. She was lounged back on her bed, her fingers hesitantly touching the skin of her breasts, lingering on her pert nipples. Her eyes were closed and a smile was on her face as she teased herself in what she thought was the privacy of her own room.

He froze in the air, every fiber of his being focused on that one word that just came out of her mouth. He couldn't even enjoy the view of her touching herself because of his razor-sharp focus on what she had just said. She was thinking of him? In such an intimate moment? He was so caught up on this that he lost concentration on keeping himself invisible. At the worst possible moment one of her eyes drifted open as her other hand traveled down her abdomen, reaching for her spread legs.

"Marshall Lee!" Fionna shrieked, an audible clap sounding as she immediately slammed her thighs together.

She had a look of terrified embarrassment on her face and she threw her arms across her chest to attempt to conceal herself. Her wide blue eyes were locked onto his, a red flush rapidly developing across her cheeks and spreading down her neck. They stayed frozen like that for a moment that seemed to drag on for a century. His hand was still on the window, his grip so tight his knuckles had turned white. Needless to say his erection had seemingly evaporated on the spot. They continued to stare unblinkingly at each other. His mind had gone blank, he didn't know what to say or do.

"Uh, hey there," he finally said, flashing her a broad, fangy smile. "I love the look. You should dress like this more often."

Fionna blinked a few times silently, her chest heaving with the short gasps of breath which were all she could take in in her shocked state. Then, she surprised and alarmed him by letting out a wail, grabbing her knees and pulling them to her chest. Her damp hair curtained her body as she buried her face in her knees, sobbing freely. His face fell as he watched her cry. He felt like a monster, this was the absolute last thing he wanted to see her do.

He didn't know if he should just leave? What exactly was he supposed to do? He would rather her reaction to catching him creeping on her be anger. He would just let her claw at him to her heart's content and swear she had scared him off and he'd never do it again. It's not like she could actually do any real damage to him anyway. He would have preferred that, he knew how to handle that. This, however, left him confused and uncomfortable. Fionna was sobbing like there was no tomorrow, her cries only interrupted by a shaky breath here or there. He hesitantly drifted over to her, a look of horrified discomfort on his face.

He reached out to touch her shoulder then paused, closing his hand in midair. She lifted her face from her knees and wiped at her tear-stained face with her forearm, sniffling loudly. Her watery, red-rimmed eyes found him.

"Y-you just had to come in at the worst possible moment," she said, her voice shaky. His eyes widened. She thought he had just happened to drift in? She didn't know he had been watching her? "How much did you see?" she asked.

"I saw enough," he answered, not wanting to lie to her, but not wanting to be entirely honest either. She wailed again, burying her face back in her knees, curling her arms around them and tightening herself into a ball. He watched her cry for a few moments, the discomfort and awkwardness he felt being replaced by concern. "Please don't be sad," he said, slowly placing a hand on her shoulder. He expected her to flinch away from the contact, but she surprised him by allowing it.

"I'm not sad, I'm so embarrassed I could die," she said into her knees, her voice sounding strained. He stayed frozen like that for some time, his hand on her warm shoulder, unsure of what to say. Her tears hadn't stopped, and she was gasping for breath between her sobs.

"Hey, c'mon, relax Fi," he said, giving her shoulder a little shake, concerned about her breathing. "Look, I should be the one who's embarrassed, not you. You were just doing your thing, I shouldn't have just let myself in like that." She looked up at him, an incredulous expression on her wet, reddened face.

"You?" she asked. "Why should you be embarrassed? You weren't just seen doing… y'know…" she let her voice die down, not wanting to put what she had been doing into words. Her face scrunched up and silent tears leaked out of her eyes. It was probably a bad idea, but Marshall sat on the bed next to her, his hand never leaving her shoulder.

"Hey," he said, giving her shoulder a squeeze. "I'm sorry." It was the truth, he was so very, very sorry. He was sorry for creeping on her, he was sorry for the awkward situation he had put her in, he was just so unbelievably sorry. His guilt was so overwhelming he would have drowned in it if he wasn't currently so focused on her wellbeing.

She surprised him by collapsing against him, and his arms wound around her of their own accord. He held her as she cried, feeling conflicted. He had never held her so close or for so long before. They had only ever shared brief, teasing touches or the very occasional quick, chaste hug. He enjoyed the feel of her in his arms, it was actually literally everything he had ever wanted, but the situation was all wrong. Why was she seeking comfort from him, anyway? She should be punching his lights out. Was it just because he was the only person available?

He had no idea how to comfort a crying woman. Physical comfort wasn't his area of expertise as he had never been on the receiving end of it. He had been abandoned by his own mother, he wasn't equipped to deal with any of this. His hand wound into her long hair, gently cupping the back of her neck as he held her shaking form to his chest. He patted her back with his other hand in a controlled, robotic way, a poor replication of what he had seen other people do.

He carefully kept his hand at shoulder-level as he patted. She seemed to be calming down. The patting motion didn't quite feel right and after a while he tried rubbing circles instead. That felt better. He did this for some time, and slowly Fionna quieted. With a final sniffle she went silent, but she didn't pull away from him. He continued to hold her and rub circles into her back, unsure of the protocol here. He realized the hand that had been cupping her neck was now carding through her hair, petting and smoothing out the blonde strands. He wasn't entirely sure when he had started doing that.

"Why did you come here tonight, Marshall?" she finally asked, speaking into his chest. He felt a shiver run up his spine at the sound of his name despite the waves of heat radiating off her body in his arms. He glanced down at her and looked back up quickly, suddenly very aware of how naked she was.

"I just wanted to see you," he said, which was not exactly a lie, but not exactly the truth, either. How could he admit he wanted to creep on her in the shower?

"I'm sorry that you saw a bit more than you wanted to," she said, and he could feel the heat from her face through his tear-dampened shirt.

"It was the most amazing thing I've ever seen," he admitted. He wished he could take the words back as soon as he said them, he was such a fucking idiot. She tensed in his arms, and he tensed too, waiting for her to start hitting him. She didn't. He looked down at her and she nestled deeper into his chest in response.

"Why would you want to see me doing that?" she asked into his chest, refusing to look up at him. He had no idea how to respond to this.

"Because it was fucking sexy? Who wouldn't want to see a beautiful woman naked and splayed out like that, moaning their name?" he had to stop talking as he felt blood surging south, remembering how she had looked lying on her back and touching herself.

"You think I'm beautiful?" she asked in a strange tone. She finally looked up, meeting his eyes.

"Yes, absolutely. You're beautiful, hot, sexy, all of the synonyms," he said quickly, feeling like he was burning up under her unbelieving stare.

"You're messing with me," she accused, pursing her lips as she considered him. Momentarily forgetting the delicate situation they were in he openly scoffed at her.

"C'mon bunny-girl, you do realize what's why I'm always teasing you, right? I'd prefer kisses and hugs, but I'll settle for shoves and punches. I'll take a beautiful woman's attention anyway I can get it."

"Why didn't you tell me this before?" she asked. He shrugged, feeling uncomfortable.

"I pretty much did," he said, feeling suddenly defensive.

"No you didn't," she retorted, her tone accusatory. "You've never told me I'm beautiful. You never told me you wanted me to kiss you. You never said any of that."

"I did too! That's basically what I've always said to you!" She let out a noise of frustration, pulling away from him and crossing her arms. He was too irritated at her to even care about her state of undress.

"It is not, you little liar! All you ever do is pester me!" she said, her voice rising with each word. He rolled his eyes.

"Of course I pester you! Were you even listening or do you have too much damn hair covering your ears to hear what I just said? I said I'll take your attention anyway I can get it."

"If you wanted me to kiss you so badly why didn't you just ask?"

"It's not something you just walk up and ask a person!"

"Why not?"

"Because you would have said no, obviously."

"How would you know what I would have said? Is this one of your vampire powers you've chosen not to share? The ability to predict how I'd answer a question you didn't ask me? Do you also by chance have an ability to sense when the worst possible moment is to show your face?"

"Because I, well, because it's just not what people do. How would that conversation even go? Would I just walk up to you and ask, 'Hey Fionna, crazy weather we're having. Say, I'd just love to taste your spit. How about we give it a go?'" He opened his mouth as if he were expecting someone to spit in it, his fangs glistening. "See? It's ridiculous."

"Oh, kissing me would be ridiculous, huh?" He took his head in his hands, groaning. She was so damn frustrating, always ready to pick a fight with him over every little thing.

"I did not just say that! You are an absolute sea lard!" He didn't mean to say that, but he didn't regret it, either. Her mouth dropped, a look of great offense on her pretty face.

"Oh! So you'll call me a sea lard but you won't ask me to kiss you," she said angrily.

He realized in annoyance she was not going to drop this. Was this her sick payback for him creeping on her? To make him ask for a kiss only to be humiliatingly turned down? He supposed that would be getting off easy to some, but he'd rather she just kick the shit out of him and call them even. He sighed, his face heating up. He had to admit he deserved this torture more than she knew.

"Fine! If it'll make you so happy," he cleared his throat. "Ahem, my darling Fionna, will you permit me to lick your teeth?" he asked in a formal voice. She let out a noise of disgust.

"Say it right!" she demanded. "Don't make it some big joke!" He sighed, taking a moment to compose himself. Of course she wouldn't let him off easy, she wanted him to suffer the same embarrassment he had just put her through. This was going to be painful. He looked down at her, meeting her angry blue glare with soft, vulnerable eyes.

"Fionna, can I kiss you?" he asked quietly, hating how pitiful the request sounded. He forced himself to maintain eye contact, waiting for her rejection to come. Her angry gaze softened slightly after a moment.

"Yes," she finally said in a clipped tone, and before he had time to even process what that meant she had leaned forward, pressing their lips together.

It was a strange kiss, as far as first kisses went, but for Marshall it was perfect. She was still angry and her lips moved against his roughly, dominating his mouth, her teeth occasionally clanking against his. She had her hands gripping hard on his shoulders, her chest pressed against his, pushing her weight against him. He leaned back slightly and she climbed onto his lap, straddling him without pulling away from the kiss.

Marshall let her manhandle him, feeling her hand winding into his hair and pulling at the roots. He gasped and her tongue slipped into his mouth, rubbing against his. He felt her absolutely everywhere and she was naked and he was uncomfortably hard again and confused as she explored his mouth, leaving no part of him untasted. She tugged at his hair again, harder this time, and his head was thrown back. The kiss broke and she kissed down his neck, stopping at the one scar that would never heal. She lavished licks and open-mouthed kisses on his bite marks.

He gasped for breath as his skin tingled and burned under her mouth. His erection strained against the confines of his jeans and the weight of her combined with the way she was squirming around in his lap as she sucked on his neck was going to drive him insane. He gripped at her back, looking up at the ceiling and praying to glob for strength. He didn't trust himself to move. He was fighting the urge to flip her over and take her, to hold her down and use her body again and again until there was nothing left he hadn't done to her.

Fionna shoved him back and he didn't resist, letting her lay him flat on the bed. She was still kissing him and her hands found their way up his shirt, feeling his abdomen. Marshall was beside himself, laying paralyzed on his back and staring up at the ceiling, gasping for breath as she used him. In all of his considerable fantasies he had never imagined her behaving quite like this. He always had to coax her or work at it or trick her into this exact situation, never had he imagined just asking her for it.

He had never before pictured her climbing on his lap and literally pushing him into the bed, throwing him around to get what she wanted. He was the one who was supposed to be doing all that. Instead he was just lying here and taking it. Wait, why exactly was he just lying here? Oh, right, so he didn't hurt her. Fionna appeared to have a similar thought as she ground against him and kissed, unable to garner a response despite her best efforts.

"Everything okay?" she asked, sitting back to look up at him. Her thighs were spread over his hips and she had her hands on his chest to brace herself. Her breasts were on full display to him, her pink nipples puckered. He couldn't seem to pull his eyes off of them. They looked so jiggly and soft, he wondered what their weight would feel like in his hands. "Hey," she said, giving his shoulders a little shake. "I didn't mean to like, traumatize you or anything Marshall, I kind of thought after everything you said you'd want this too."

"What?" he asked, shocked. She pulled herself off him and he noticed a warm, damp spot where her pelvis had been resting on him. She was wet for him. He groaned, gripping his hands into the sheets and twisting. "Don't be an idiot. I fucking want you so bad."

"Then why are you just lying there like a beached sea lard?" she taunted.

"Glob, because, fuck, I don't think I'll be able to stop once I start," he admitted, his voice strained. "I kind of lose control over myself when I get like this… I don't want to hurt you."

"You're not going to hurt me. I'm a tough girl, I can take it." He let out a shaky breath.

"I don't think you understand what I want to do to you right now, my good little girl."

"I said I can take it," she said stubbornly. He felt his resolve cracking. He sat up slightly, lounging back on his elbows as he considered her. She glared at him, and he smiled. He thought that she was the most beautiful when she was mad.

"I would wreck you," he said.

"Do you promise?" she asked, and that was it. She was on him, shoving him into the bed by the shoulders, her mouth crashing against his. The way she moved her mouth on his wasn't so much a kiss as it was a fight for dominance. He allowed this for a moment as the last of his resolve crumbled like a failing dam. It unleashed an ocean of sheer desire that crashed upon him in waves as he grabbed her hair and jerked her back, hard. "Finally," she breathed as her back slammed into the bed.

He was on her, licking and sucking, dragging his fangs against her skin threateningly. She moaned openly, her thighs spreading and making a perfect place for him to put his body. He pinned her down, sealing their bodies together. He ground his covered length against the wet warmth again and again, feeling as her wetness dampened the material between them.

A hand snaked up and groped her breast, the flesh bulging around his spread fingers. His mouth made it to her chest and he took one nipple into his mouth, sucking hard. He toyed at the other one, flicking at it with his thumb. She squirmed and said something, but he couldn't quite catch it. His heart was pounding in his ears and his lust overwhelmed him, driving everything else out.

He continued his assault on her breasts, his face buried in the soft flesh as she writhed, her thighs clenching around him. Her hands were twisted into the fabric of his shirt, pulling and straining as her back arched. She might have said something else, but he was so focused on devouring her nothing else mattered. She jerked, attempting to get his attention by kneeing him in the gut, hard. He groaned, pulling his mouth off of her, just enough fleeting control over his body to manage this.

"What's wrong with you?" she screamed into his face. He was immediately irritated, slamming the breaks on his body in a way that was exceedingly painful for him.

"I tried to warn you," he yelled back, forcing his grinding hips to still. He shivered as he fought for control over his body, his demonic half screaming in protest. "You're lucky I still had enough control over myself to stop." She threw her head back, growling at him like an animal.

"I didn't say I want you to stop! I said I want you to take these off," she said, grabbing at his clothing. "Your jeans rubbing against me like that is going to give me a rash."

"Oh," he said, looking down at himself and realizing for the first time he was still completely dressed. Fionna jerked her hips up to nudge him expectantly when he didn't move on his own.

"Are you going to take them off?" she supplied.

"Yeah," he said, faintly embarrassed as he pulled away from her and shrugged his arms out of his shirt. She began scrambling for the button and zipper of his jeans as he pulled his shirt over his head. She shoved his jeans down to his thighs and he kicked out of the material, her desperate mouth back on his. He shook his leg, having trouble getting the clothing off completely with most of his mind honed in on the way her hand had just slipped into his boxers.

She grabbed him at the base and jerked him, the rough, irregular rhythm of her hand suiting him just fine. He grabbed and squeezed at every part of her body he could get his hands on, lost in the feeling of her body against his. He had to get inside her, like right now. He loved the feeling of her hand on him, but he had been waiting long enough to take her, he was not waiting another moment. There would be time in the future to slowly make love and explore each other's bodies. Right now was not that time. Right now he just wanted to give in to his urges and fuck her desperately.

He hooked a hand behind one of her knees, pulling it up to her abdomen, forcing her body onto her side. She had one leg pulled up and the other straightened out, which he mounted, lining himself up against her entrance in a single, fluid motion. He rested her raised leg against his shoulder and rutted against her opening, bumping the head of his cock off her tight hole.

Fionna moaned, and he leaned down to capture her mouth in a kiss. Her leg on his shoulder moved with him, spreading her legs open impossibly wide. He didn't worry about overstretching her leg, as he knew how bendy and agile she was from seeing her in fights. He was worried, however, about just shoving his entire length in and pounding her. He fought against his urges to slow down and work her open as gently as he could manage.

Their mouths hungrily moved against each other as he grabbed himself at the base and began wiggling his cock against her hole, coating the head with her wetness and teasing her. She seemed to like it, based on the way she was moaning directly into his mouth as he moved. Once the head was slippery he rolled his hips, slowly working it inside her inch by inch.

Marshall moaned as he experienced the feeling of being inside her for the first time. She was almost too tight, but she was moaning and eager and her legs were spread so wide it helped her accommodate his length. He filled her completely, stopping once his hips ground directly against hers. He reached a hand down and ran his fingers over her clit, groaning when she clamped down on him in response.

He slowly rocked his hips and counted the seconds as he gave her time to adjust, running his fingers over her clit again and again until they were soaked. He pressed his open mouth against the calf of her leg that was resting on his shoulder, biting at it to prevent himself from hammering into her. He didn't bite hard enough to draw blood, but it was a close thing.

She jerked her leg in surprise and reached up to shove his face away from her leg. He grabbed at her, easily pinning both of her wrists together with one hand above her head without really meaning to. She cried out at this as it caused her spread legs to be pushed open a bit more and for subsequently his cock to somehow push further in.

He began thrusting into her, perhaps harder than he should have, but he really only had so much control over his actions at this point. He was only human, after all. Well, sort of. He was using every ounce of self-control he still possessed to make sure he didn't sink his fangs into her exposed neck and drain her dry while he fucked her raw. He licked and sucked at what he could reach of her breasts to keep his mouth otherwise occupied, completely losing control of his body.

His hips began moving of their own accord, pounding into her rapidly. She was clenched around him so hard, gripping him so tightly that every time he pulled out it was nothing short of a miracle that he could manage to slam it back in. But, he did so again and again, his reward being the purest form of pleasure he had ever felt. He wasn't sure how long he pounded into her like this, but he didn't want it to ever end. His vision flickered in and out as the waves of pleasure accompanying each thrust threatened to peak inside him. She was so tight, so wet, so hot all around him, it didn't feel real.

His thoughts were muddled and hard to formulate, but as his orgasm approached he vaguely remembered he needed to ask permission to ejaculate inside her. Right, they hadn't talked about that. He looked up from her chest and saw he still had both of her hands pinned above her head with one of his. She was on her side the way he had positioned her, but her face was tilted to bury into the mattress, a pained expression on what he could see of his face.

Contrary to what he believed, he did in fact have control over himself, because when he saw her like that something clicked inside him to stop. He immediately froze his hips, let go of her hands, and cupped her jaw gently. He was upset to see her fingers had turned white from how hard he had pressed her wrists into the mattress. She made little fists and rolled her wrists as soon as he released her, pulling her hands down from over her head.

"Are you okay?" he asked, alarmed to see fresh tear tracks on her face. He took her raised leg off his shoulder, helping her off her side so she could rest on her back. He remained buried inside her the whole time but was suddenly numb and disconnected to the sensation of her moving around him. He brushed the hair out of her face, his thumb tracing a wet tear track down her cheek.

"I'm fine," she said, but she didn't look fine. "Go ahead, I'm tough, I can take it." He shook his head, frowning.

"I don't want you like that. I want you to enjoy it, too. Was I too rough?" he asked, already knowing the answer. Fionna hesitated for a moment before answering.

"A bit toward the end," she admitted, averting her eyes. "I meant it, though. I can deal with it. Just go ahead and finish." Her words disgusted him, like actually revolted him to his core. He pulled out of her, ungluing his body from hers.

"I don't want you to deal with it. I don't want to hurt you. I'm not some monster who gets off on something like that." His eyes ran over her and he saw little red marks all over her collarbone and breasts from his fangs scratching against her flesh. She couldn't contract vampirism from shallow flesh wounds like that but they disturbed him all the same. It looked like she had been ravaged by some sort of wild animal.

"Why didn't you tell me to stop?" he breathed, running his hand over her angry skin as if he could brush the imperfections he had caused away. He flinched when he noticed a scratch mark running up the length of her side accompanied by some early onset bruising in the shape of his hands.

"I did," she said. The horror he felt upon hearing her say that was indescribable. He tried to jerk away from her to put some distance between their bodies but she grabbed him, holding him in place. He could have easily shoved her off him but he didn't want to hurt her. "Marshall Lee, I wanted this, and I still do. I'm the one who initiated this."

"You didn't ask for this," he said, staring down at how he had marked up her beautiful chest.

"You tried to warn me, I knew the risks, this is on me, not you," she said soothingly. Why was she trying to comfort him? He couldn't wrap his mind around this. "It… It got a bit too rough, but I did enjoy most of it," she said. "I'd like to finish what we started."

"There's no way you enjoyed that," he said flatly. She found his hand and brought it between her legs, pressing his fingers against her. He felt the hot wetness there and was ashamed to say how turned on he felt from it.

"I did," she said, sighing softly as his fingers began to move, gently stroking and rubbing her clit.

"No, I don't want to hurt you again," he said, but his actions betrayed his words. He continued to rub her clit, and she pressed closely against him, which he allowed. Her hand found his hardness and wrapped around it, pulling at it in slow, thorough strokes.

"I don't think you will. I feel like you'll be more careful this time," she said. He believed her, he did feel more in control. The risk was still there, but he found he cared about it less and less the more she played with his cock.

"Okay," he said against his better judgment. "But this time, you should ride me. You'll have more control that way… I don't think I trust myself to be on top of you right now."

"Alright," she said, pressing her hands on his chest, urging him to rest back on the bed.

She mounted him like it was the most natural thing in the world, which he supposed technically it was, in a sort of world history, human reproduction way. She lined him up and sank down on his length. His mind was immediately overwhelmed with pleasure and there was simply no more room for thoughts of world history as she began to move.

She rested her hands on his shoulders as she rode him slowly. His hands flew to her ass but he simply held it. He gripped it roughly here and there but overall he maintained a good control over himself. It felt amazing to recline back and watch her work, grinding and bouncing on him, her face flushing from the effort.

She was beginning to pick up the tempo and he watched as her breasts bounced with the motion of her hips. He felt the urge to lose himself and let his demon-half take over but he resisted it. All he had to do to stay present was glance at the red marks all over her chest.

His hands moved from her bottom to gently cup her breasts. She flinched slightly before relaxing into his touch. He took each of her breasts into his mouth in turn, licking and teasing them to peak, being extra careful of his fangs. Fionna seemed beside herself, she had her eyes closed and a look of determined concentration on her face as she rode him harder, chasing down her release.

He had to turn his face away from her breasts as he felt his orgasm building up, not trusting himself. He grabbed her hips instead, helping her maintain the frantic rhythm she had worked her way up to. Her walls were tightening around him and he felt overwhelmed by the pleasure of feeling her like this. His eyes flew open, he had forgotten to ask for permission to come inside her. He was so close, he had to warn her.

"Ah, Fionna," he began, groaning as she squeezed around him. It felt so impossibly good, it was like her walls were trying to actively suck the come out of him. "Fionna, I'm going to… I'm going to fucking come."

"Go for it," she said, and she didn't stop riding him. She gripped his shoulders, bringing herself down on him a few more times before her walls began rhythmically clenching and pulsing around him, crying out as her orgasm hit her. He followed her, having no chance of holding back, his balls tightening in a familiar way as he ejaculated deep inside her. He didn't think he had ever come harder in his long life.

She collapsed on him and he wrapped his arms around her, holding her close. They were both sweaty and gasping for breath, completely overwhelmed in the pleasure they had just shared. She continued to pulse around him for some time, his cock giving a little twitch in response to each one. He held her through it, rubbing her back in that way that just felt so right and kissing her shoulder, which was right in his face.

He remained inside her for a long time. He was completely soft by the time she shifted off him, the sweat coating their skin having dried them together in a way that was unpleasant to separate. She sat up and looked down on him, smiling.

"I'm glad you came to visit me tonight," she said. He felt a pang of guilt, not for the act they had just shared, but for his actions leading up to it. He was a disgusting creep, he didn't deserve to experience what they had done.

"I-I was actually coming to kind of… creep on you," he admitted, his orgasm's afterglow dampened a bit by his self-loathing.

"I'm glad you came to creep on me tonight," she said without missing a beat. She had a playful smile on her face, which was beautiful, but he didn't deserve to see it. He frowned, feeling as though she must have misunderstood him.

"Fionna, I'm a bit obsessed with you," he said desperately. She cackled obnoxiously in response.

"Marshall Lee, I'm more than a bit obsessed with you," she retorted. He groaned. Why was she always picking fights with him about the dumbest things? He wasn't trying to tease her, this was a serious confession, dammit.

"Fionna, I came here to watch you shower like a pervert," he blurted out, his heart hammering away in nervous anticipation. She was silent for a moment before getting up and grabbing his hand, pulling him to standing.

"Okay Marshall, and now I'm going to watch you shower like a pervert," she said, pulling him toward the bathroom with a devilish expression. He followed her, a bemused smile on his face as he considered her. No matter what she always seemed to find a way to fill him with joy despite his best efforts to wallow in misery.
