Tossing and turning in his bed, body sweaty and exhausted, the Commander still couldn't fall asleep. No matter how tight he kept his eyes shut, he was ceaselessly presented with the image of a certain captain in all sorts of positions, each lewder than the last. Levi on his knees, sucking him passionately. Levi bent forward with his hands against the wall, muffling a moan. Levi on his back tied to the bed, begging to be fucked. Levi…

Erwin sat on his bed decisively. This had to stop. He could not let these futile fantasies get the better of his rest.

And yet… Every single one of his muscles craved Levi's skin and more. After all, everybody was supposedly fast asleep by now… He could certainly just walk straight to the captain's room without encountering anyone. Amidst his musings, he could already picture the short man's surprised and adorably angry reaction, miniature fists hammering the blond's broad chest with all their might. In the pitch blackness of this cold and unwelcoming room, the handsome commander couldn't suppress his warmest smile.

All clear to the left, all clear to the right. In this very moment, as he almost tiptoed cautiously along the corridor, the intimidating leader looked like a clumsy teenage boy. He was already halfway there when he noticed a faint light emanating from the communal showers. Suddenly regaining his seriousness, Erwin walked in, ready to scold the undisciplined cadet.

Yet in the bathroom was no cadet. Instead Erwin found himself faced with the curious sight of a little someone who was furiously scrubbing the floor on their hands and knees, a very tiny towel barely concealing their bum. The commander licked his lips in anticipation. He couldn't believe his luck.

'Well, what do we have here? If that isn't Captain Levi on all fours cleaning the bathroom floor.'

The aforesaid captain jolted and dropped the sponge he was holding.

His voice resonated in the room at last, low and surly: 'Tell me it's not what I think.'

Unfortunately for him, it was. Levi painfully turned his head to meet muscular legs in tight trousers and military boots. The tall Adonis was yet again smiling at him with great amusement and obvious concupiscence.

'I'm sorry I interrupted your cleaning. Please go on.'

'There's no way I would resume cleaning while you're here, get the fuck out' the short man spat, jumping to his feet.

But the blond giant blocked the other's way and effortlessly undid the small towel that fell to the ground. He then pressed a hand on the raven's shoulder before turning him around.

'What? Are you putting on the bossy commander act again?' Levi hissed.

He tried to look away, but his suspicious frown was met with inflexible ice blue eyes.

'On your knees', Erwin ordered.

The captain blushed but grudgingly complied, getting down on his hands and knees again with the worst possible grace.

'Are you happy now, you arrogant prick?' Levi snapped, overcome with redness and humiliation.

'Resume your cleaning', Erwin said quietly.

'What?! I'm going to show you some cleaning, you fucker!'

The commander's only reply was to press a foot against the pale back, rendering any move impossible.

'Do it.' Erwin's foot became more insisting on Levi's back.

Levi shivered but resumed his task, for once focusing less on cleaning with care than on trying to save face, his pride badly hurt and his round bottom up in the air. In reality, he was already more than half-hard from this little scene. Those were his favourites and Erwin knew it oh too well.

'What a view', the blond remarked, putting his hand to the bulge that had formed in his underwear.

'If you're going to stay here then at least shut the fuck up!' Levi barked, his face bright red.

But the commander ignored him: 'I can see everything from here.'

'Cut it out!'

In this instant, Levi felt Erwin's tongue entering his crack, and yelped at the invasion.

'Aah Erwin! Stop that right now!'

The skilled tongue was wetting his hole in such a lecherous way it made Levi whimper audibly, his hips twitching with every lick. Once he deemed his subordinate wet enough, Erwin inserted a thumb inside.

'G-aah..! What the fuck do you think you're doing?!'

Erwin withdrew his thumb and crooked two other fingers in: 'I want to hear your whines again, Levi.'

But this time the captain's pride took over and he clenched his jaw hard to suppress any sound.

'Oh, I see; trying to resist me, aren't we?'

Levi heard the sound of trousers being pulled down and soon enough hot, thick flesh was brushing against his rear. The raven did shiver keenly, his ass irresistibly pushing against Erwin's crotch. The blond patiently stroked the juicy cheeks in front of him with his cock, fighting the desire to enter them all at once.

'I'm going to fuck you so deep...' he murmured to an eager Levi, before wrapping a hand around the captain's cock and starting to pump him softly.

The short man couldn't bite back a moan this time, to Erwin's great delight.

'Turn around.'

Putting words into action, the commander cupped the other's small, tense jaw and turned it towards him.

Levi was now facing Erwin's almost terrifyingly lustful gaze, and his even more terrifying erection, hard flesh making its way to the corners of the raven's mouth as Erwin gently pulled Levi's bottom lip to slowly push his cock in. Truth was Levi was so amazed by the enormous member that had just entered his mouth it took him a moment to start bobbing his head up and down, his tongue accompanying each of Erwin's thrusts with slow licks as his mouth sucked rhythmically.

'Ngh- Levi...' After a few thrusts, he added: 'Pull back. I want to fuck you on the floor.'

He pushed Levi away lightly. The raven resumed his initial position, palms and knees on the cold floor. Erwin almost immediately slammed in, firmly holding the captain's waist before reentering him again.

Levi let out a hiccup, trying to relax to take the commander's full length in. Erwin's suave voice came to his rescue, his fingers rubbing one of Levi's already hard nipples as he spoke: 'On all fours doing your little cleaning, anyone could see you... '

'Which is why I do it in the middle of the night, you massive idiot!' Levi fought back.

'Of course. You were not hoping to get caught again, were you?'

'What?!'

Erwin leaned closer: 'But tell me, this ass is just for me, isn't it? ' 'Isn't it?' he repeated, clasping a possessive hand around Levi's neck as he thrust faster.

'Ah- y-yes!' Levi finally cried out, bending down, his face now pressed against the bathroom floor.

Erwin whispered into his ear again: 'How do you like the cold tiles against your burning cheek?'

'Fuck- you…' Levi replied, in a voice that sounded disappointingly more pleading than fierce.

Erwin started pounding him even deeper, balls slapping against Levi's ass relentlessly.

This was too much for the short man. He bit his towel in an attempt to conceal his loud grunts before coming hard on the floor. It didn't take long for Erwin to climax as well, unable to resist the sight of his flushed subordinate finally giving in.

It took all the chillness of the bathroom to help cool down their overheated bodies. Still panting and a little dizzy, the commander observed: 'Looks like you would need a good cleaning, Captain…'

He glanced at the showers and kissed the small of Levi's back before asking: 'Are you ready for round two?'
