Work Text:
In the weeks and months after Eren’s death, Mikasa grew to dread the setting sun, to view the encroaching darkness outside as a mirror of the darkness inside her mind. Without him, without answers to the questions she’d been too afraid to ask, she felt adrift, like a dead leaf tossed around in the currents of life, unable to control her direction. Her body seemed to accept this state wholeheartedly, denying her the comforts of sleep more often than not. Most nights she would lie awake, replaying the last moments of Eren’s life, trying to determine whether she could have done anything to stop his thread from being cut short. Sometimes she would be able to gain a few minutes or hours of light rest, though that came with the risk of now-familiar nightmares of blood and steel.
She made the mistake of letting slip her issues to friends and acquaintances and was bombarded with potential solutions, and in her desperation she tried them all: warm milk, deep breathing, bitter-tasting herbal tinctures, every pill and powder and potion available at the pharmacy. None of these remedies could stop her wandering thoughts or calm her body enough to give her the relief she so desperately needed from her physical and mental weariness.
One night, she lay in the dark, having dutifully choked down some valerian root tea whose taste of sharp herbs and dirt came through even after adding copious amounts of cream and sugar, cursing herself for her ability to withstand even the strongest sedatives.
“I would do anything to get some sleep,” she murmured to no one.
Anything? a ghostly voice responded.
Mikasa sat upright, adrenaline animating her body, more awake and alert than before. She definitely wouldn’t sleep at this rate. “Hello? Is someone there?”
I’m here, the voice said. She could not divine the source of the low, silky tone; intensely masculine but with an amused bent, as though the speaker were smirking at her.
Not here here, it clarified, as though it could sense her confusion. I’m not some intruder, but I can show myself if you want to speak face to face.
“Show yourself,” Mikasa demanded, her voice displaying more resolve than she felt.
The darkness in the room shimmered, moonlight and shadow undulating until they coalesced into the form of a man floating above her bed as though he sat in an invisible chair, his powerful limbs splayed in a posture of confident nonchalance. He wore a black suit and white shirt, open at the collar to reveal his collarbone and a hint of muscular chest, and held a delicate china teacup in one hand, taking occasional sips from it. But what Mikasa noticed most was his face: a strong, masculine jaw, a sharp slash of a noise, dark hair hanging over eyes that glowed an otherworldly silver, and a pair of curved, black horns atop his head.
“What are you?” she wondered in an awed whisper.
“Oh, don’t look so shocked. You’ve never seen a demon before?” the man said. Mikasa shook her head. “Then I suppose it’s your lucky day to be visited by a high prince of Hell.”
“I— I don’t understand.” She shook her head and rubbed her eyes, but the man — the demon — still floated above her bed with such ease that she felt as though she was the one out of place, not him.
The demon let out an exasperated sigh. “You want to sleep, I can help you sleep. In exchange, you help me.”
“Help you do what?”
“Are you just going to repeat everything I say?” he griped. He drained the last of his tea and waved the cup away, making it waver and vanish, the inverse of his entrance into her room.
“Well, excuse me for not knowing how to interact with a demon who shows up in my bedroom in the middle of the night,” Mikasa fired back, crossing her arms and glaring up at him.
Her annoyance piqued the demon’s interest; his lips curved into a small smile. “My name is Levi. I’m an incubus, which means I get my life energy through sex. The exchange is simple: you let me fuck you, and I’ll make you come so hard you’ll sleep like the dead.”
Mikasa frowned, holding his gaze with skepticism bordering on anger at his audaciously blunt offer. “Sounds like you’re trying to trick me into letting you drain the life out of me.”
“Tch. Not the best metaphor, then. Sleep like a baby? I just didn’t want to make you think of babies when I’m offering you as many screaming, gushing orgasms as your body can handle.” He shrugged as the filthy words rolled off his tongue, as unconcerned with his speech as Mikasa was scandalized by it.
“I don’t know. I mean… Eren…” she mumbled. Her gaze dropped to her hands, which lay clenched in her lap. My hands were meant for him, she thought. My touch, my body… they were supposed to be his.
“No, they weren’t,” Levi said flatly. “Where the hell did you get those ideas?”
Mikasa blanched. “You can hear my thoughts?!”
“Yeah, and they’re a huge fucking bummer. I get that you had a thing for Eren, but let me assure you, he is exactly where he deserves to be. Eternity isn’t long enough for that piece of shit.” He snorted, a soft sound of contempt punctuating his words. “I can make you feel very different. Maybe some things you’ve never felt before. I’ll show you if you want.”
“So you want to fuck me so you can show me what it’d be like if you fucked me?” She cocked one eyebrow at him.
“No, I mean literally show you.” She nodded and he reached out to her, two fingers extended like he was blessing her, and pressed them to her forehead for a moment. Images flooded her mind faster than she could process them: her throaty cries, his rasped moans and words of praise, skin slapping against skin, the squeak of her bed, the musk of sweat and sex.
Cold prickles of awareness broke out on Mikasa’s skin, goosebumps sprouting where she imagined he would touch her, contrasting with the sudden warmth and wetness surging between her thighs.
Levi watched as the familiar blush of arousal spread across her cheeks, coloring her gloomy countenance into something more lush and lively. “Don’t throw your life away for a dead man. Don’t give up one of the few things that makes life worth living.”
She was silent, still unsure, so he added, “Have you ever considered why the pleasures of the flesh are Hell’s domain and not Heaven’s? Because they’re too good. It would be so much harder to keep the weak little humans in line if they realized that their limited time on earth was much better spent fucking than praying.”
Mikasa’s breaths came heavily, her body’s restlessness melting into arousal. “Look, I want to say yes, but I just don’t understand what the downside is supposed to be. There’s no way I just get fucked and then go to sleep. There’s got to be a catch. And what if I can’t sleep tomorrow?”
“I don’t know if you’ve noticed, but the people who are out there speaking with great authority about Hell and demons are the ones who are trying to claim your souls in the name of Heaven. They don’t exactly have an incentive to tell the truth,” Levi said. “Sleeping with a demon creates a bond, but I only feed from you as often as you want me to, and I never take more than I need. If anything, I’m at your service. And your cervix.” His lips quirked into a brief smile; she grimaced and shook her head at his approximation of a joke.
“And this is really going to work? I’ll be able to sleep?” she asked nervously, grasping for more reasons to refuse him but finding none.
“You’ve never jerked off so many times you fell asleep? Or whatever the girl equivalent of jerking off is?”
She shook her head. “I haven’t even thought about touching myself since Eren.”
“But you’re thinking about it now,” he said, his voice deepening to a rumble, like the ominous yet strangely comforting sound of distant thunder.
“It’s kinda your job as a sex demon to turn me on, isn’t it?” she asked. The acknowledgement of her arousal combined with the knowledge that he could hear her inner thoughts as though she was speaking them made her bold; there was nothing to hide from him.
“Not all of us work that way, but it’s better for me when the other person enjoys it. Their energy tastes so much better.” Levi swallowed thickly, his own arousal growing along with Mikasa’s. There was power in her beneath the hardened sedimentary layers of her pain and grief, the hint of it already beginning to intoxicate him, and that power would only grow stronger once he unlocked the secrets of her body one by one.
“If you still have doubts, maybe this can convince you,” he said, opening his mouth and sticking out his tongue, flexing it like he was lapping at her now-slick pussy and not the air in front of him. Mikasa watched his tongue grow in length so slowly she thought she imagined it, until it thickened and grew a fork at the end, resulting in two prehensile shoots of muscle that undulated independently of each other.
Her mouth opened unconsciously, her breaths coming out in long, desirous pants. “I want that on my clit.”
“Not yet,” he said. “There’s a process. Just let me do my thing and I give you my word, I’ll blow your mind so many times you’ll forget your own name.”
She sighed, sadness tingeing her excitement. “I think I need that.”
Levi floated downwards, settling on top of Mikasa, his hands planted on either side of her shoulders, his weight pinning her to the bed. She shifted her hips beneath him, pushing her nightgown up her thighs as she sought out his bulge. She worried about staining his expensive-looking suit with her wetness, but she found herself sliding against soft, smooth skin that was diamond-hard when she pushed against it.
“Where did your clothes go?” she asked, trying to figure out when she stopped gripping the shoulders of his sportcoat and started gripping the firm, defined musculature of his shoulders.
“To Hell,” he replied with a smirk. “I can’t make your clothes disappear, though.” He reached down and yanked her nightgown over her head, leaving her naked beneath him. His skin was comfortingly warm against hers, as though he were a mortal man and not a demon, and she found herself completely unashamed of her nudity. She felt so bashful even thinking about taking her clothes off in front of Eren, and—
“No more Eren,” Levi interrupted her train of thought, and bent his head to kiss her.
Mikasa didn’t know what she was expecting from a demon’s kiss, but the lush press of his lips was not it. He kissed her like he was drinking her in, sucking at her lips and twining his tongue — now returned to its normal size — with hers. He stoked her arousal like a precious flame, letting her burn brightly but not out of control. He cupped her face in his hands as he kissed her, stroking her with his thumbs and marveling at the softness of her skin.
“You smell like sunlight and strawberries,” he murmured against her lips, following his words with a soft bite.
She pulled away from him, looking at him with amusement. “I didn’t know you were so sentimental.”
“Shut up. I basically get drunk when I feed. Don’t mind the bullshit I say,” he grumbled.
“Don’t want to admit you want me really fucking badly?” she countered.
“Not as badly as you want me,” he replied, reaching between their bodies to grip his cock and rub its length up and down her spread pussy, waiting for her expression to register exactly how much length he had. His eyes flashed silver with excitement when her kiss-swollen lips formed a perfect surprised O.
“Can you make your cock change size like your tongue?” she asked, canting her hips so she could rub her soaked folds up and down his erection, coating them with her moisture.
“Uh huh,” he sighed. He wasn’t even inside her and he was already feeling feverish and frenzied. His lips stretched into a rictus grin and he kissed her to hide his excitement from her; he needed to warm her up before he could give her everything he had, and he didn’t want to scare her off with his intensity.
Once Levi managed to calm himself, he strayed from her lips, pressing hot, open-mouthed, desperate kisses along her neck, shoulders, and collarbone, finding that she liked a hint of teeth at her pulse point, but she cried out and squirmed beneath him when he sucked hard at the juncture of her shoulder and neck. He could actually feel her dripping on his cock while she moaned. Cradling her close with one hand, he let the other wander, tracing his fingertips over the lines of her body, the firmness of muscle and bone contrasting with the soft pliability of her breasts. He focused his efforts there, alternating between soft caresses and pinches, and the sting of his fingernails tracing around her areola and over her nipple. When he finally grasped her breast, she shrieked and bucked beneath him, her back arching as though he had branded her.
“More!” she demanded, her eyes shut tight so as to focus on the intense sensations. He obliged her, kissing her deeply and grabbing her breasts with both hands, massaging them roughly, pinching and pulling at her nipples while she devoured his tongue and soaked his cock. After a little while he wrenched himself away from her mouth and attacked her sensitive, swollen nipples, mindlessly sucking and biting at them, snuffling like an animal. Mikasa’s fingers grasped at his hair, tangling her fingers in it and occasionally pulling when pain won out over pleasure. She soon found he liked the pulling, and that he’d work her even harder when she threaded her fingers through his dark hair and yanked with all her might. When he looked up at her, his pupils were blown wide, a thin silver rim surrounding inky blackness.
“Don’t you ever fucking stop,” she admonished him after a few moments of staring.
He scoffed at her. “I haven’t even gotten started.” Before she could even comprehend what was happening, he had her legs spread and her knees touching her shoulders, his thumbs pulling her labia apart so he could kiss her pussy and swirl his lengthening tongue around her clit, surrounding and massaging it with the forked end. She trembled beneath him like he was electrocuting her, her entire body fluttering with unspeakable pleasure. Levi’s eyes rolled back in his head as her juices coated his tongue, sweeter and more powerful than even the finest wine. Within minutes she was coming, half-words and incoherent sounds spilling forth from her lips, a primitive language that Levi could understand nevertheless: Yes, more, I love this, I never want you to stop.
So he obliged her, backing off from her sensitive clit momentarily and snaking his tongue down to her entrance. Mikasa made a questioning noise, wordlessly asking him if he was going to fuck her with his tongue.
“Mm-hm,” he hummed, already excited to see how she would react to his tongue filling her pussy, its tip pressing against her g-spot and rubbing furiously. Her moans grew raspy, her throat raw and dry from overuse, but she still managed to let out a healthy wail at his internal massage, and somehow got even louder when he traced circles around her clit with his fingertip. He gave thanks to his demonic nature for allowing him to keep a superhuman pace; whereas a normal man would get tired from the repetitive motions, he drew strength from her frantic responses. This allowed him to keep going even as Mikasa’s inner muscles clenched around his tongue, denoting her second orgasm, then a third in quick succession.
The fourth came on much more slowly, but promised to be a big one when she started quaking in his arms. She was incoherent, her inner monologue completely switched off, her thoughts focused solely on Levi and the inhumanly wonderful things he was doing to her. Her nerves felt like they were frozen and on fire at the same time, heat and cold running through her in equal measure, her muscles alternately clenching and relaxing. Her skin felt cool and slick, though she could not tell if that was from her sweat or his, his saliva, or her cum. As he continued working her clit with his fingers and her g-spot with his tongue, she began to feel warm again in her chest and between her legs, shaking and keening as though possessed, then exploding and spurting cum all over Levi and herself as she screamed and sobbed through her climax.
“I’m not done with you yet, but let’s take a break,” he suggested, curling up next to her and pulling her against his solid, muscular body.
“Water!” she gasped, and he produced a glass of perfectly cold water from thin air, which she gulped down in such a frenzy that rivulets escaped from the sides of her mouth and dripped onto her breasts. Levi lapped the water from her skin and conjured another glass for her, refilling it until she was sated, capturing any errant drops with his tongue. She buried her face in the crook of his neck, her warm breath stirring his arousal, but he told himself to stay still, to let her decide when they could get back to it.
“I feel like I haven’t touched you at all,” she said after a while, lifting her head so she could bask in the shining silver of his eyes.
“Touch all you want.” He rolled over onto his back, opening himself to her. She propped herself up on one elbow and let her eyes and hands rove over him, from the softly amused, almost affectionate look on his face, down to his corded arms and thick chest, his segmented and defined abdomen, and then the flat, slightly sloping plane that led to his pubic hair and the largest, most beautiful cock she’d ever seen. It was half hard, resting against his thigh, with a streak of moisture adorning the tip.
“Is this where the term Leviathan comes from?” she asked with a grin, wrapping her fingers around its impressive girth and working up and down his length.
He returned her smile, excited by her excitement. “Uh-huh. People think it means a sea monster, but—”
“They haven’t gotten a chance to see this monster?” she interjected.
Levi snorted a laugh. “I didn’t realize my shitty jokes could be transmitted through our sex bond.”
“I guess we’re both gonna learn some new things tonight,” Mikasa replied, looking down at him with a heavy-lidded gaze and tightening her grip. He soon grew fully erect, his huge cock pointing at the ceiling, drops of precum forming and spilling over her fingers.
“I need your mouth or your cunt, something, just… more…” Levi panted, desperate for contact. “It’ll fit, I’ll make sure it doesn’t hurt.” He willed his cock to produce more precum, the massive organ becoming slick and shiny as Mikasa stroked him. She nodded, her energy returning, growing along with her enthusiasm to take his cock inside of her. Without a word she gripped him by the base, lifted herself up, and lowered herself onto him, sliding down as though she was made to fit him.
“Oh, fuuuuuck,” she groaned, her eyes sliding shut in bliss. She stayed still, trying to get used to the sensation of being so completely filled, of having his cock igniting every nerve ending inside of her, but Levi couldn’t wait any longer. His cock began to move inside her, thickening and stretching her, rubbing her inner walls the way his tongue had done. Mikasa went off like fireworks, lapsing back into her feral, languageless state, broadcasting every sensation as sighs and gasps and yelps. Levi grasped her by the waist and thrust up into her as fast as he could, slamming his hips into hers so fast it sounded like applause.
She tipped her head back and howled at the overwhelming rush of sensation, being filled and fucked within an inch of her life. Each thrust felt like he was spanking her pussy with each impact, making her come a little, her pussy clenching around him, emitting little spurts of cum every time he retreated. In the midst of this he rolled her over, landing on top of her, still pistoning in and out of her without missing a beat. She bent her legs back before he thought to do it for her, taking him even deeper.
“Fuck, Mikasa!” Levi moaned over the sounds of her fevered howls and skin slapping skin. “I’m not gonna last much longer.”
“Behind,” she managed to say; he didn’t understand, so he searched her mind for the mental image he hoped to find: him on his knees behind her, driving into her even faster and harder than before, his tongue snaking down to tease and fuck the tight bud of her asshole, her pussy dripping with cum and saliva, soaking the sheets beneath them.
“Whatever you want, my dirty girl,” he groaned, trying not to come just from the thought of him inside her twice over. He flipped her over and replicated the mental image exactly, thickening and lengthening his cock so he could fill her up completely, bending down and doing the same with his tongue on, then in her ass. Mikasa shook and sobbed beneath him, her body wracked with an ecstasy beyond comprehension, each cell in her body singing in perfect harmony.
Levi felt his orgasm building, starting in his balls and inner thighs, coming on fast and uncontrollable, more intense than anything he’d ever experienced. Usually he’d siphon a little of his partner’s life force while coming, still able to maintain his rationality during the transfer of power. This was something else entirely, a ball of white light and energy growing inside him, threatening to engulf him once it exploded.
Please, please don’t let me kill her, he pleaded with himself as he tipped over the edge, just before his thoughts faded into utter incoherence. I need to have her again.
His orgasm overtook him, the entire world going blinding white except for himself and Mikasa, flashes of intense color flying past him. Then even she disappeared in the blinding glow and his vision went entirely white. A tiny, rational voice wondered whether he was dying, but he found himself okay with the prospect.
When he came to, he sat upright, panting as though waking from a nightmare. Mikasa lay a warm hand on his chest, rubbing it in absentminded circles.
“You’re okay,” she said softly, letting out a deep yawn. “You just fell asleep for a few minutes.”
“Oh,” he sighed. “You’re alive.”
Her smile was crooked, loopy with exhaustion. “Very much so.”
“I came so hard I was worried I killed you.” His hand sought hers, squeezing it once, unwilling to vocalize the fact that killing her suddenly seemed like the most heinous taboo when she’d been a complete stranger a couple of hours earlier.
“Well, if you did, I would’ve died the happiest I’ve ever been.” She brought their clasped hands to her lips and pressed a soft kiss to his knuckles. He pulled their hands back to him, kissing her hand in return, as if to tell her that affectionate gestures were his job, not hers.
He looked around the room, suddenly disoriented, the surroundings and this woman both familiar and unfamiliar. “Was that flower always there?” He gestured towards a small clay vase on her nightstand that held a single bright blue bloom.
Mikasa poked her head up and furrowed her brow. “It was dead before, or at least dying. I was thinking of throwing it out. Did we do that?”
“I think we did,” Levi replied, letting out a confused sigh of a laugh. He pulled the blanket over Mikasa, tucking her in as she curled up on her side in preparation for sleep, her eyes already closing. He reached over to pluck the blue flower from its vase, inspecting its unfurled petals and the soft dusting of pollen inside them. Struck by an overwhelming urge, he nestled the flower in Mikasa’s hair near her ear, pleased by the contrast of blue on black, of the flower’s delicacy and the strength of the woman whose mind and body could disarm a prince of Hell. His usual protocol was to slip back through the closest portal that would take him to his quarters, but the thought of sleeping alone — without her — made him shudder. Instead he cuddled up next to her and brushed his lips against her forehead, drunk on the combined scent of flowers and sex and this wounded woman who’d somehow ensnared him. Smiling at how fortunate he was to come across such a precious mortal, he closed his eyes and allowed himself some much-needed rest.
When Mikasa woke the next day, she was alarmed to find that the clock on her nightstand read 1:47 in the afternoon, and even more alarmed to find that she felt refreshed and awake, ready to start what was left of the day with a clear head and an elevated mood. She flopped back onto her pillow, staring at the ceiling with a bemused smile on her face. The sheets were cool and dry beneath her, a far cry from her soaked bed a few hours earlier. The vase by her bed was empty; perhaps she’d thrown out that old flower like she’d meant to, and her demon lover was just a strange, vivid dream.
She waited for Levi’s voice in her head to tell her otherwise, and was disappointed when she did not receive a response. Sighing with disappointment, she got up to shower, trying to determine a productive activity for the remaining daylight hours: maybe weeding the garden, or stopping off at the market for more eggs and milk. Undressing in the bathroom, an azure blur caught her eye in the mirror: a crushed flower, as blue as the sky, tucked behind her ear. She cast her gaze down her body, inspecting herself and finding a bruise — no, two — no, dozens of them. Fingertip-sized on her breasts, larger and deeper ones on her neck and shoulders and thighs, and even a couple of scabs in the shape of Levi’s teeth where he had bitten her.
Her fingers skated over her wounds, making her shiver and whimper at the combination of pleasure and pain that radiated throughout her body. One hand drifted between her legs, spreading her free-flowing fluids around, circling her clit and fingering her pussy in a poor imitation of Levi’s supernatural prowess, while she replayed the previous night in as much detail as she could remember.
Not once, not even in passing, did she think of Eren.
I need Levi, she thought, fucking herself with desperate intensity as she braced herself against the sink. I need to feel him again. I need his hands on me and his tongue wrapped around my clit and his cock stretching me until I feel like I could burst. I need to come on him, all over him, as much as I can handle it.
“Come back tonight,” she whispered as she chased her peak. “Please.”
About fucking time you said something, Levi’s voice echoed in her head. I was starting to think you didn’t want me back.
Mikasa laughed aloud, joy and surprise and blessed relief enveloping her, pushing her over the edge. She came, her pussy pulsing around her slick fingers, her lips crying out for her demon lover.
Levi let out a deep, rumbling moan. That’s my girl. I’ll be there at midnight. Don’t bother wearing clothes this time.
She smiled at her reflection in the mirror, her mind buzzing with anticipation, and her eyes flashed silver in the afternoon light.
