Hello lovely people and thank you for taking the time to read!
I hope you enjoy this story, inspired by Eruri sex with my boyfriend as always.

Apologies in advance for any mistakes, English is not my mother tongue :)

Also please note that, due to 's writing constraints, I may soon not be able to post works anymore –my stories are not exactly K-rated as you can tell.
FYI all my works are available on Archive Of Our Own though :)

Twelve days, Erwin reflected. Twelve days he hadn't slept with Levi. Twelve days he had come up with the twisted idea of starving the little raven of sex. The commander's insatiable thirst for knowledge had always brought out the most Machiavellian ideas in him. And he was so curious to see how long he would resist fucking the short captain… How long he would fight the desire to tell him how much he loved him and how powerfully attractive he was. Yet truth was a darker part of him had also the vicious desire to see Levi abandon his proud composure and crawl at his feet.
In the first few days though, none of that had happened. The little man, seemingly not noticing anything, had merely ignored him. And yet, after a week, Erwin had started to witness the most unusual things. Levi staring at him during meetings, brushing against him when they ran into each other in the corridor, touching his hand when handing out documents, even rubbing against his thigh under the table! Erwin, who was smiling to himself at the thought of it, got pulled out of his daydreaming by a loud noise.
Levi had just come in, without knocking. That and the massive scowl on his face did not, to put it mildly, augur well.
Witnessing the small man already break down after less than two weeks was so entertaining the tall man had to conceal an amused smile behind his hands folded in front of his face. Regaining his commanderly composure, he raised an interrogative eyebrow:

'Is anything the matter, Levi?'

The other flatly disregarded his question and made his way to the desk. He ran a scrupulous finger along the dust that was piling up on the desk and snorted, wrinkling his nose: 'This place is as fucking dirty as ever.'

Erwin knew Levi was genuinely obsessed with cleanliness, but this was just some obvious excuse for coming closer, dark bangs brushing against the blond's face. Erwin calmly replied, putting papers aside on his desk: 'And yet God knows how feverishly you had cleaned it last time.'

The remembrance of his recent cleaning adventures in the commander's office, where he had ended up being fucked on the desk, brought a light colour to the captain's cheeks. He yet deadpanned, bending on the surface under the pretext of brushing dirt away, his back dangerously close to Erwin's face: 'But I can see that cleaning isn't one of your priorities.'

'You seem to have other priorities yourself. Don't you have anything better to do than coming to my office? Shouldn't you be working on at least one of the five reports you owe me?'

Levi snapped back: 'Don't lecture me like some shitty underling.' Seeing the disapproving frown on Erwin's face, he went on, brushing a hand against Erwin's arm as he pretended to leaf through the pages of a folder: 'What are you working on, anyway?'

'A report for the higher-ups, mind you.'

'I thought you just sucked them off.'

'Not everyone uses the same methods as you.'

Before Levi could come up with a cutting reply, Erwin continued: 'You're doing a great job at pretending you're here to complain about the lack of cleanliness, Levi. Unfortunately, I have a clear view of your erection from here.'

Levi blushed with a mixture of shame and glee. It wouldn't be long now before Erwin would start one of his deliciously perverted power plays and screw him on the table. The raven's cock twitched at the thought.
But Erwin, looking away from the crimson bundle of nerves that was insensibly rubbing against his desk, opened a folder and seemingly gave it his full attention: 'Leave me alone, now; I need to work. You are quite mistaken if you think you can get what you want by just wiggling your ass. Other topics require my attention and action.'

Levi gulped at the frostiness in the commander's voice. But he stood up to the affront and put a hand to the erection Erwin was trying to conceal under his desk: 'Looks like someone doesn't think so.'

Erwin, afraid his body would show his extreme arousal, collectedly replied: 'Don't be so full of yourself. You shouldn't be mistaking a simple physiological reaction with irrepressible desire.'

Levi, in a fit of anger and pique, straddled the blond and seized him by his jacket collar to kiss him wildly. Yet this time Erwin's impassive lips did not kiss back. The little man pulled back, disconcerted.
Erwin, for his part, was quite simply amazed. To think that the ever-so-scornful Captain would shamelessly relinquish all dignity just for a hasty fuck... This experiment was definitely getting very interesting.

'All right,' Erwin sighed, 'if I give you what you want, do you promise to get out of my office?'

'Wh-what?' Levi stammered.

Erwin undid Levi's trousers, unleashing the short man's straining erection before adding: 'You could have thought of a more subtle way of expressing what you wanted. Because this is a bit… rough, even for you.'

Levi let out a loud gasp before replying: 'It's true that I am not a master of manipulation like you.'

Erwin rubbed his thumb against the head of Levi's cock. 'Indeed, and you'd better be working on your tactics instead of coming here waving your ass around.'

The captain replied by biting mercilessly into Erwin's collarbone, earning him a grunt from the tall man. But the latter grabbed Levi by the throat, forcing the raven to look at him: 'Listen to me. I will make you come, and you will leave right after that.'

This was the only warning Levi received before being flipped over onto the desk by two strong hands that removed his trousers, leaving him in a fairly humiliating position, his bare bottom offered to Erwin's implacable gaze. Next thing he knew, two fingers coated in some greasy and viscous substance entered his ass.

'What the fuck was that?!'

'Oil.'

'O-oil? You had it ready at your desk?!'

'Yes. You see, I knew you would pop in eventually. I haven't failed to notice your rutting cat glances and ass-wriggling lately. It's funny how only a few days after I have stopped fucking you you've started developing such a wanton behaviour.'
As he spoke, he curled his fingers deeper, making the small man yelp. The captain extended a futile hand towards Erwin's crotch, but the commander held him down with a hand pressed against the back of his neck.
After a few more thrusts, Erwin pulled his fingers out. Levi knew this was a sign the tall man was finally giving in. Soon enough, the blond would take his own trousers off and fuck him roughly.
But to the short man's dismay, Erwin turned him around, and the raven found himself lying on his back on the desk. Erwin wrapped a hand around the captain's neglected cock before entering his ass again with two fingers. Levi, his eyes rolling back, squirmed eagerly, lewd sounds escaping his parted lips.

'One orgasm and then you're out of here, are we clear?'

Levi's eyes shot open: 'What?!'

'Are we clear?' Erwin repeated, putting more pressure on Levi's prostate.

'Aah- yes! Crystal!' Levi gave in.

Both of Erwin's hands were working him so deftly he knew he wouldn't be able to hold back much longer. He attempted to unbutton Erwin's shirt, but the blond grabbed his hand and slammed it onto the rough surface of the desk.

'Eh?'

'Don't you even try.'

'What the fuck-? Aren't you going to-aah!' Erwin gave his wrist a vicious final twist, making Levi spurt out involuntarily. The captain, covered in his own cum, tried to come to his senses. Erwin was still looking at him in his cold and disinterested manner. 'Now put your clothes back on and let me get back to work.'

'W-what?' Levi uttered in disbelief. Seeing no reaction from the commander, he clenched his fists and protested furiously. 'You... fucking sadistic sociopath!'

Erwin raised a silencing hand: 'Stop thinking that you are irresistible. I can't satisfy every single one of your animalistic impulses.'

'Yeah well maybe I will end up satisfying them with somebody else', Levi retorted, readjusting his clothes.

'That's a very hypothetical 'maybe', I'm afraid', Erwin simply replied, now supposedly focusing his attention on a report in front of him. 'Make sure you close the door when you leave.'

He didn't have to say it twice. The infuriated captain darted towards the door where he stopped and turned abruptly:

'Next time you can clean your office yourself, and shove the broom deep inside your ass you sick bastard!' he barked, banging the door behind him.

Alone again at his desk, Erwin let out a stifled laughter. 'Well', he pondered, as his thigh brushed against his own erection, 'I suppose something needs to be done about this now.' He undid his trousers and started masturbating, his head still full of memories of Levi's reddened cheeks and lascivious cries. In this instant, a new idea came across his mind. Oh, this was going to be a good week.
