Author's Notes: HighQueen here. 3DMG seems to be a fetish floating all around this fandom, and I've gotten quite a few requests for it. So here you go. This takes place after the events of Shingeki no Kyojin. Just assume it ends happily somehow and there aren't any Titans left.


3DMG


Eren had secretly wanted it for a very long time.


It started after the fall of the last Titan.

They didn't need the 3DMG anymore, but they preferred to use it. They were still soldiers, protecting mankind. They didn't kill Titans anymore, but they patrolled the villages at night often enough.

Thieves, murderers, rapists.

Even though the Titans didn't exist, there was a different breed of monsters that did.

And it was easier - ridiculously easy in fact - to catch them and stop them when on 3DMG.

After the efforts of the soldiers, crime decreased drastically. The criminals knew that they couldn't outrun skilled ex-Titan-killers on 3DMGs. Most towns were safe, and some of them had no such reported incidents.

Patrol duty became more of a formality. And for Mikasa, who had always been a natural, using the 3DMG was something of a habit.

She and Eren used it whenever they were patrolling, and even when they had a long journey to make. Most of the other soldiers who had survived preferred to as well, just for convenience.

But for Mikasa, there was something liberating, something refreshing, about flying through the air at a breakneck pace, the wind rushing through her hair.


Eren watched her, arcing herself as she leapt forwards, her body curving back like a bow. She moved so gracefully, so seamlessly. She made using the 3DMG an art form, and she was beautiful to watch.

An image flashed in his mind, of Mikasa, arching up against him in the same way, responding to his fingers as he touched her -

"Fuck," Eren cursed, as he felt himself go hard.

Damn it, this is not the time!

Still, he couldn't help it. She twisted her lithe body, her thin white shirt covering her waist - but Eren could imagine what was beneath it, imagine how her muscles would clench when she moved.

He imagined slamming her against the wall then, wrapping her up in the wire cords and restraining her - or riding her, as they whipped through the air - it was a sudden thought, a wild thought, an impossible thought...

But Eren couldn't help the desire that coursed through every fiber of his being.

Watching her maneuver herself through the air was suddenly appealing, so very appealing.

He was doomed, he realized.

Mikasa on 3DMG turned him on.


Mikasa noticed that Eren was being silent, which was unusual for him.

"Are you alright?" she asked, turning her head back.

Her dark eyes met his emerald ones.

"I - I'm fine," Eren choked out.

He told her about it, a few nights later, when they were making love.

The idea of it had tortured him, more than enough.

She was pliant and willing beneath him, her fingers scraping lightly across his back as he touched her, thrusting into her again and again, his lips hungrily attacking at her neck.

Once she finally came, Eren told her.


"I want to fuck you when you're on the 3DMG."

His voice was a rough whisper, and his brilliant green eyes were dark, so dark. He was staring at her predatorily, and she could hear the desire in his voice.

It sent a chill down her spine, but excited her, excited her to the core.

As for what he had just said - Mikasa could hardly believe her ears.

"Y-you're joking right?"

"I'm not."

He nipped at her bottom lip, his gaze intense as his hands squeezed her thighs.

"You're so fucking hot when you're using it, so perfect."

He pulled her closer against him, grinding into her, and Mikasa felt her entire body blush at his words.

"It makes me want you, so much. And I don't think I can take it anymore."

"That's not even possible." Mikasa kept her voice steady, trying to calm her thumping heart.

As wild, as crazy as the idea was, she couldn't help but feel more than a little turned on by it.

"Shut up," he growled at her, "It is. I can do it."

You probably could. I could too.

"Eren-"

He crashed his lips to hers then, ending the discussion. He didn't bring it up again.


Eren had always been an intense person. He had also been the kind of person who never gave up on what he wanted. After the Titans had been dealt with, Mikasa found that a lot of his passion was directed towards her.

It had made him an entirely thrilling lover.

Though he hadn't mentioned the 3DMG fetish after that night, she could feel his gaze, boring into her as they sped through the Forest of Giant Trees.

Mikasa had never felt like a prey before. She had always been the huntress.

And yet, at that moment, feeling Eren's hungry gaze on her back, she couldn't help but feel an anxious excitement creeping up within her.


Mikasa looped her body around a tree, flipping over midair to avoid a branch.

Eren's eyes remained fixed on her form, the way her hips twisted and rotated when she moved, the way the tight white pants accentuated her legs...

She leapt off of a branch, arching up and thrusting her hips forward to propel her ahead.

That bitch. She's deliberately being a fucking tease. She's had it.

Eren picked up his pace, shooting off the nearest tree like a bullet, straight towards Mikasa.

You are the prey now. And I am the hunter.


Mikasa gasped, when Eren's form suddenly hurtled into her from behind. His arms wrapped tightly around her, and he crushed her to him.

"Eren-" she yelped, blushing heavily.

She shot her grapple hook into the bark of a tree, and they landed heavily on a branch.

"We have to-" Mikasa began, but was cut off as Eren turned her around so that she faced him, and shoved her, none too gently against the bark.

He pressed himself against her, so that she could feel the hardness in his pants, rubbing against her. He attacked her mouth with his lips then.

It was a demanding kiss, and Eren grabbed Mikasa's wrists, slamming them back on to the tree trunk over her head.

He started touching her then, and Mikasa gradually felt her resistance ebb away, until she was writhing and moaning under his hands.

He had torn her jacket off, and ripped the buttons of her white shirt open.

"Eren. Eren. Eren," she cried his name again and again, as his lips travelled downwards over bare skin.

His green eyes glinted in triumph.

She knew he loved overpowering her. It gave him some sick pleasure. And this time, she was too into him to care, and was more than willing to let him do whatever he pleased.


There was nobody in the forest but the two of them, bathed in the silver moonlight that filtered through the trees. The branch they were on was high, very high, but neither of them was afraid.

Mikasa didn't quite know how long they had been there. She had lost all sense of time. Everything was just Eren, the touch of him, his lips, his hands, his scent.

She let him ravage her, giving herself into him, until he finally pulled back.

"Mikasa..." he said softly, his eyes half-lidded as he gazed into her own.

"Mm."

"There's something I want you to do for me."

He didn't leave her gaze, and his hands were softer, gentler now, as he caressed her sides.

"What is it?"

Eren's hands moved down, and he pulled off the harness that held her 3DMG swords, though he left the rest of the gear on.

"Eren, what are you-"

"Shh." He pressed a finger to her lips. "They'll only come in the way."

Mikasa's eyes widened, as Eren loosened his own harness as well.

"Eren... you can't possibly mean to-"

"I want you to do it, Mikasa," he told her. "We both know how talented you are with it. You can."

"Eren..."

Mikasa's stomach fluttered wildly. She couldn't believe what she was hearing.

"I've wanted it for so long," he told her, his finger tracing down her stomach, her abs, circling her bellybutton.

He flicked the button of her pants open, and Mikasa gasped.

"Mikasa," he looked deep into her eyes as he slid a finger into her.

She moaned.

"Eren!"

He moved his finger against her, his nose brushing against her.

"Please. For me," Eren whispered, kissing her softly.

She was losing her mind. He was kissing her so tenderly, so sweetly. Eren slid a second finger into her.

He had even said 'please'. Eren never had said 'please' to her for any such thing. He always had too much ego.

"Mikasa, come on," he urged her, "I can tell you want it too, you know."

He was right. She was wet, so wet. She was ready.

"You can do it," he traced her lips with his other finger, kissing her cheek, "Mikasa?"

And then she lost it.


CRASH!

The branch they had been standing on toppled to the ground. Mikasa had slashed it away with one of the swords, before letting the rest of them fall to the ground.

They would have fallen without the support, but Mikasa had Eren pushed tightly against the tree bark, the wires of her 3DMG, and his, anchoring them to the tree.

Eren's eyes glinted as they met hers, and he smirked, feeling rather happy with how the situation had turned out exactly the way he wanted it.

It was crazy. The entire situation was crazy. Here they were, suspended hundreds of feet of the ground, with nothing but their 3DMG to hold them up.

He loved it.

Mikasa's chest was heaving, and her eyes were narrow.

"You don't look to happy," Eren teased.

"Shut up, Eren," she growled at him.

He grinned cheekily, his hands trailing teasingly up her sides.

Mikasa flushed, but gripped the firing piston of her 3DMG, adjusting herself over him.

This time, Eren didn't mind her dominating him, not even a tiny bit.

"Come at me with all you got, Mikasa."


An hour and a half later, two soldiers trudged slowly through the forest in silence.

"Damn, Mikasa..." Eren finally said after a while.

"What?!" she cried defensively.

"That was good," Eren breathed, "Really really really good."

Mikasa flushed heavily.

"Best yet, I'd think," he said.

"I - I didn't think it would actually work," she admitted.

"We pretty much destroyed that tree," Eren said, though he didn't sound like he regretted it one bit.

"We destroyed a couple trees," Mikasa muttered.

"Plus your 3DMG. How'd ya manage to do that?!"

"I don't know!" Mikasa snapped, looking down at her damaged 3DMG, which was the reason they were walking. "It's not my fault! They're not meant to be used for..."

She trailed off, unable to finish her sentence, still slightly overwhelmed by what they had just done.

"For sex?" Eren finished for her, grinning, "Don't blame the 3DMG, Mikasa. You're the one who lost control."

"I - what - Eren!" Mikasa went bright red, though she couldn't argue with him.

He did have a point. She had lost control. She couldn't help it - he had been so insistent before, and Mikasa had always liked the 3DMG.

"The way you were going at it, I'd think you wanted it more than I did," Eren said, his grin widening when she blushed harder.

"Wow, Mikasa," he began, when she didn't say anything.

"Shut up, Eren!"

He laughed.

"You were awesome, though, you know. We should try that again."

"No!" Mikasa looked scandalized, though a part of her mind was thinking off a hundred different ways in which they would be able to use it again.

"Not right now, of course. We'd have to get your 3DMG fixed first."

"And what am I supposed to say when they ask me how I ruined it?!"

"Oh yeah," Eren smirked at her. "Is this the first time you've broken it?"

"Yes. Even while killing Titans, I never had, not even once."

"Huh. The famous Mikasa, finally broke her 3DMG. If only people knew how..."

"Eren," she cried, "Why are you getting such a kick out of this?! This is all your fault! We should exchange gears, and you can say that you broke yours."

"It's not my fault," Eren said, laughing again, "You're the one who went - crazy with it."

Mikasa didn't respond, until she felt his arm around her shoulder, the other one under her knees.

"Eren! What are you doing?!" Mikasa yelped, as he picked her up in his arms, bridal style.

"I'm not switching with you," he said, "But given it is partially my fault that you broke yours, I can at least do this much."

"Put me down! I can walk!"

"This is better," Eren winked at her, before leaning down to press a kiss against her forehead, sending her heart fluttering all over again.


"Hey Mikasa," Eren said, three days later, as he walked into the room where she was eating dinner with the other soldiers. "Picked up your 3DMG for ya. It's fixed now."

He placed it on the floor next to her, before sliding into the seat opposite. Mikasa refused to meet his eyes, her cheeks heating up as she remembered the incident.

"How the heck did you manage to break it anyways," Jean asked. "Especially now given there aren't even any Titans around."

Eren coughed into his drink, and Mikasa glared at him.

"Oh - just an accident," she said.

"But you're Mikasa!" Connie exclaimed. "You don't get into accidents."

"Gee, Mikasa," Eren piped up innocently. "If you're still crashing into trees on that thing, it probably means you need practice. If you want, I can help you out tonight."

The other laughed at his joke, but Mikasa felt her face go red.

Eren's hand found hers under the table.

When she met his eyes, they were gleaming, and she could practically read his thoughts.

Tonight. Again.

He squeezed her hand, and she gave him a small nod, her heart hammering.

Eren broke into a grin.


Author's Notes: HighQueen here. I hoped you liked that, it was the best I could come up with for this prompt. I'm sorry if people wanted a more explicit scene with details of them actually doing it with the 3DMG. To be honest, I tried, but I couldn't figure out how exactly I would write it, and how that would even work. So I guess some of it can be left to your imagination.

HurricaneKatty has a couple of prompts she took dibs on. I've read bits of what she's written so far, it's great, so you have that to look forward to!

The next one I'm taking up is probably Titan!Eren x Mikasa though it'll be tough. Let's see. I've seen it written before, exceptionally well at that. Or I may do one of the other prompts. Keep sending us your requests, we'll try to do as many as we can!

Thank you so much for all the reviews and support! You have all been wonderful!
