Levi groaned deep in his throat as Mikasa tightened her grip on his hair and surged upwards, flipping him with a twist of her body. The breath left his lungs as he was thrown onto his back, taking in the sight of Mikasa chasing her release above him.
Hips gyrating and her head tilted back, she took him in deeper. Mikasa exposed the soft, sensitive flesh of her neck that he loved to taste. He tried to sit up, tempted by the pale, smooth skin, only to be stopped by her hand pressing firmly on his chest as she arched and canted her hips forward to take her pleasure.
They were both covered in a sheen of sweat, and the room reeked of sex, the air redolent of pheromones, reflecting their mutual desire. Levi had lost track of the time that had passed since she stood at the door of his office; she had finally returned from a month-long training with the new recruits. He knew her absence was necessary for their defenses, but he had missed her, missed the feel of her body clutching around him.
The first coupling had been savage and messy; they hadn't even made it beyond the door. Levi had pulled her in and locked the door, the pair only undressing each other enough for him to sink into Mikasa with her back pressed against the door. She had bit down hard enough to mark him as she came, and he was fairly sure he had returned the favor of marking her body. Levi knew that he must have left fingerprints along the backs of her thighs where he had gripped, trying to keep them upright as he rode through his release.
Now, as she glided atop him, no light came in from the windows. Only the blaze of lamplight played off of their bodies as they moved together, writhing and grasping. Levi brought his hands up to reach for her hips, but she denied him, hands as quick as lightning. She pinned his own hands above his head; he growled his frustration, wanting to sink his fingers into her hips and press into her deeper.
It was a deserved torture, he knew; Levi had brought her to the edge and pulled back one too many times before she had enough and flipped them. He tried to squirm free anyway, stopping when Mikasa leaned forward to press down on his wrists more firmly, the heat in her stormy, half-lidded eyes sending arousal straight to his groin.
Instead of struggling further, he took advantage of the position, darting his head to catch a nipple in his mouth. The action made her gasp, and him groan as her muscles tightened around his cock in reaction. He did it again and felt the stuttering motion of her hips telling him she was close.
Mikasa abandoned her previous position, leaning into his chest as she came closer. The grind of her core against the base of his cock gave the stimulation she needed to end her own torment. He lifted his hips to meet her thrusts, feeling a savage pride at the weakening of her grip on his arms. Only they could do this to each other; only they could disassemble and wreck each other, over and over again, to the point of exhaustion.
A broken cry poured from her mouth as she started to shake, approaching her climax. Tearing his hands free, Levi held her to him as he pounded into her from underneath, guiding her over the edge. His spine tingled as her contractions bore down around him. The tightening and the cry of his name sent him toppling over as well. Burying his face in her neck and pressing her to him, he rode out the waves of his orgasm.
They lay like that for a minute, catching their breath in a calm before the storm. Levi knew it wouldn't last; the hunger was too powerful. This wouldn't end until they were both too exhausted to move. Even then, he somehow knew he would wake hard and pressed against her, his body seeking to be joined with her own even in sleep.
Still shuddering as she pulled away, the shock of the cooler air on his cock caused him to jump after being buried in her heat for so long. Mikasa lay on her side next to him, looking wholly debauched and undeniably stunning.
Her fair skin was flushed and sweaty, strands of her disheveled black hair sticking to her face. Reaching out, Levi ran a thumb over her kiss-swollen lips before cupping her face in his hand. The fire in dark, grey eyes told him their activities were far from over, but he took in her beauty during this small armistice.
Levi wasn't sure what he had done to earn her love, and he sure as hell didn't feel he deserved it, but he would be damned if he threw the chance away. He would gladly burn for the chance to spend another moment buried inside of her. The uncertainty and risk ahead were great; he didn't know if they would make it out alive, but he did know one thing: the image of Mikasa like this was what he wanted to see behind his eyelids as he died.
Desperate need rising again, Levi pulled her towards him and turned her so his chest was against her back. He pressed open-mouthed kisses against that spot on Mikasa's neck, which he loved so much, and felt his body begin to rise to the occasion. She gasped at the sensation and arched back against him. Levi thanked whatever greater power saw fit to bless them both with this quirk of ancient bloodlines, her own stamina a match for his.
The pinpricks of her short nails digging into his arm didn't quell his ardor when he rubbed circles around the nub at the apex of her thighs, drinking in her gasps and mumbled sounds. The aim of this round wouldn't be denial, Levi thought. He wanted to bring her to completion as many times as she could bear and reduce her to the same ashes she burned him to.
As Mikasa bucked her hips back against him, seeking relief from the fire he stoked, Levi slid himself inside. He remained unmoving as his fingers continued their work, undoing her. He used his forearm to stop her hips from thrusting, pinning it across her hips while his hand increased its speed. She was swearing and arching as she came and tore an involuntary groan from him at the pressure surrounding his length.
Not giving her a chance to recover, he turned her onto all fours. Molten arousal surged in his stomach as he took in the wetness smearing her and the contractions of her entrance, visible as she was spread before him. With a slowness that was counter to his own desires, he entered her again, drawing out the friction.
Levi stilled when she started thrusting against him, enthralled by the sight of her fucking herself on his cock. He watched while each roll of her hips made him disappear inside her, entrance stretching to accommodate his girth. Breaking his gaze away before the sight sent him into another release, he stilled her movements with his hands on her hips.
He could read her body like a book by now and set a rhythm that had her balling up the sheets into clenched fists, crying out unintelligible words swallowed up by the pillows. Reaching down, he pulled her strong, slender frame up against his chest. Her legs spread to accommodate the new position, and he stabilized her with an arm across her chest.
One hand worked her nipple, and the other migrated down from her stomach to where they joined. Levi pressed his thumb firmly against her and was rewarded with an arch of her back and a cry of his name. He moved the thumb slowly, feeling the dampness leak from her entrance.
Levi didn't let up when she came, sensing she had another left in her before he needed to let her recover. One of her hands reached back and buried itself in his hair, tugging his mouth more firmly to her skin. The other left deep marks as she gripped him, utterly losing control as she fell into another orgasm.
He slowed and brought them both down, knowing she needed time to recover from the twitching of her muscles. He propped himself on his elbows, filling her with languid thrusts while he waited for her eyes to open again. They kissed deeply, enjoying the feeling of being entwined with each other. Levi knew she'd want payback for the pleasure he had wrung from her, but he was content to continue the slow pace for as long as she let him.
Time passed in a haze as they took turns being the aggressor, pushing each other to their limits. They devoured each other, not holding back; they were safe in knowing the marks and strains would disappear quickly owing to their uniquely matched abilities.
The sun shone again, lighting up Mikasa's fair skin by the time they were ready for a respite. A knock on the door broke them apart. He didn't move, instead sending the unfortunate soul scurrying with a hissed demand that Jean cover training with the squads today. Levi pulled Mikasa's form greedily against him. He knew they would have to collect food at some point at least, but he was not yet prepared to let this short bliss end.
The sleepy, murmured 'I love you' against his neck drove him to pull the blankets over them, wincing at the filthy state of the sheets they lay on. He would probably need to burn them. No amount of washing would remove the evidence of their night. Levi couldn't bring himself to care, returning Mikasa's sentiment and settling for a brief rest. A nap would recharge them enough to finish scratching the itch left by a month apart. The rest of the world could wait.
