Notes: Here comes a whole chapter of smut!

I squeezed as much as I could into this chapter: role-play, power play, spanking, restraints, orgasm denial, plus some old stuff with a new twist. I hope you enjoy!

Previously: Armin, Levi and Erwin discussed the possibility of staying friends once the threesome ends, as well as new things they want to explore in their sexual exploits.

Chapter 17: Power and Punishment

Levi

From the moment Armin Arlert arrived in Erwin's quarters that evening, Levi hadn't been able to suppress the jittery sensation in his stomach.

Like the Commander, Armin was dressed in his formal military uniform - high brown boots, black trousers, white shirt and a long green coat that reached his knees. In contrast to the other men, Levi was wearing a freshly laundered training uniform, minus the ODM gear. He'd been the one to request they dress up for like this for the role-play. Emphasising a visible power difference made things all the more exciting for him.

He studied Armin as they sat together in the living room, having a last minute talk about their impending activities. The librarian looked older and more serious in the formal uniform. Handsome in a refined and mature way. While he didn't possess the same air of casual authority as Erwin, Levi could easily imagine himself bending to this man's will in the bedroom.

Between the two of them, I'm sure they'll be capable of putting me in my place tonight…

The anticipation of the men teaming up to take charge of him was almost too much to bear. He tried focusing his attention on the obligatory pre-sex talk Erwin was giving their guest.

"Don't forget, you can tell us to stop at any time. Either by using the safe word red, or just by saying stop. But remember – if Levi says stop, you don't need to. He'll say red if he genuinely means it."

Armin nodded. He looked charmingly determined with his hands folded on his lap, like he was at an official meeting. In fact, with all of them in uniform and discussing important matters, it felt exactly like that.

Over the last few weeks, Levi and Erwin had demonstrated to Armin several role-play scenarios of varying levels of intensity. They'd discussed everybody's preferences, and casually tried out a few new things with him – including spanking, using restraints, and incorporating more dominating talk. From this the young man got a better idea of his limits and comfort zone. Last week, they'd devised a role-play scenario for the three of them to perform together tonight.

Armin was very interested in letting the other men take control of him. But Levi and Erwin felt it was best to start with a scenario where one of them was submissive instead. It seemed like the safer way to build up a level of trust, by showing they were willing to make themselves vulnerable first. And to demonstrate there was no shame in enjoying and embracing a submissive role.

"Just follow my lead if you're unsure," Erwin said. "And please let us know if you want us to tone things down."

The young man nodded. But his fidgety fingers picking at the fabric of his uniform coat betrayed his nerves.

On impulse, Levi added, "Just remember it's only a game. We want you to enjoy this too, so don't do anything you're uncomfortable with. Alright?"

Armin's lips quirked as he nodded again. His shoulders relaxed and he sat up straighter in his chair.

"Right then, are we ready to head in?" Erwin asked.

As they all stood up, he took Levi's hand, and reached out to grasp Armin's as well. Linked in this way, they walked down the hall to commence the first part of their planned activities for the night.

"Bend over the desk, Mr Ackerman."

Levi obeyed, the hard wood pressing against his stomach and chest. He squirmed, acutely aware of the two pairs of eyes on him. His own gaze was fixed on the dark grain pattern of the wood in front of his face.

He'd been in this position plenty of times – both in this very room, and also a few times in Erwin's official office. Given the mishap that had occurred last time they'd played around in the office, they decided it was best to use the private study in Erwin's quarters tonight.

Funnily enough, the scenario they were enacting now was similar to what Armin had accidentally walked in on all those months ago in Erwin's office.

Levi wished he could see Armin's face to gauge his current mood. I'd feel a lot better about this knowing he's still eager to participate. But I trust Erwin to take care of him.

During their practise sessions over the past few weeks, Armin had admitted his squeamishness about slapping bare skin. Hence why they'd agreed for Levi to be fully dressed for this scene. Armin had also been uncomfortable when he'd watched Erwin using a belt on Levi, so that was another thing they were forgoing for the time being. This role-play would just be a relatively light punishment scenario.

"This is your own fault, Mr Ackerman. You could have avoided this so easily…"

Erwin's deep, authoritative voice made Levi shiver. He pushed past his instinctive desire to give up control. It was always more fun to cause a little mischief first.

"Tsk. I know you love it when I misbehave. It means you get to show off your power over me."

"I suspect you're the one who gets the most pleasure out of this, Ackerman." He paused, heaving a dramatic sigh. "Armin, I'm sorry you have to see this. But I just can't seem to get through to this disobedient soldier. Perhaps having a witness to his punishment might shame him into compliance."

Levi snorted. "Good luck with that, Commander."

The floorboards creaked as someone took a step closer behind him. Then Levi felt the hard sting of a slap on his ass. It sent heat rushing straight to his groin, and his grip on the edge of the desk tightened.

"Mark my words - we will turn you into an obedient soldier, whether you like it or not."

"And you think Arlert will be able to help you? That boy's far too nice for your sick, twisted games, Commander."

He dearly hoped Armin would prove his teasing words wrong.

When the man stops second guessing himself about everything, he's got good instincts for this type of assertive, dominant role. But doing a proper role-play scenario is a whole other level. I hope he's not regretting taking part…

Levi would be mortified if Armin decided to call the whole thing off. But he also didn't want the man participating in anything that made him uncomfortable. Besides, even if this wasn't to his taste, he knew the man well enough by now to be certain he didn't judge him for his unusual sexual preferences.

Levi tried to amuse himself by imagining Armin's shocked expression at this very moment. Or more likely, the man was probably struggling to keep a straight face. He'd been prone to bouts of nervous laughter during their recent practise sessions.

"Do you hear that, Armin?" Erwin's voice became softer, melting like a block of ice over a fire. "The Captain doesn't think you're up to this." He heard Erwin move a pace away, probably back towards Armin. Levi could clearly picture him putting a comforting arm around the younger man, or squeezing his shoulder. "But you're such a good boy, aren't you? Do you think you can help me discipline this bad soldier?"

Armin replied in an exaggeratedly firm tone, "Yes, I'd be happy to help, Commander." There was a note of amusement in his voice.

Not wanting to spoil the scenario, Levi decided to embrace the man's nervousness. "I don't know what you're laughing at, Arlert. Maybe you're the one who needs to be bent over a desk and punished for not taking this seriously enough."

There was a rustle as someone stepped forward, and then another hard smack on Levi's ass. Fuck, Erwin's not going easy on me just because Armin's here, he noted with approval.

"You're the one who needs disciplining, Ackerman. Not Mr Arlert." Erwin's footsteps receded a few paces, over to where the younger man stood. "Armin, do you think you can prove the Captain wrong? Would you kindly assist me with his punishment?" The words were honey-sweet and inviting. As much of a dangerous weapon as his former authoritative tone had been.

"Y-yes," Armin said, more shakily than before. Levi heard a lighter step behind him this time. His pulse kicked up a notch as the scent of lavender drifted to his nostrils. From their practise sessions, he knew the man needed encouragement in moments like this.

"Don't fool yourself Arlert." Levi sneered. "You're much too nice to do something like this."

There was silence for a few agonising beats. Levi cursed himself. Had he unintentionally put the man off with his challenging comment?

He opened his mouth to break out of his 'disobedient soldier' role, and ask Armin if he wanted him to tone down the snarky dialogue. But before he got the words out, he felt a light slap on his backside.

Actually, it barely warranted the term 'slap'. It was really more of a gentle tap.

Levi was on the verge of laughter himself now. He didn't want to discourage Armin, but he also wanted a stronger effort from him. He knew from experience the man could do better.

"Is that all you've got?!" Levi turned his head to get a glimpse of Armin. The librarian was biting his lip, mouth twisting in agitation. "I like it hard," he growled, "so don't hold back."

He turned back to face the desk. Another slap landed on his ass – firmer this time.

"That's more like it," Levi panted, shifting his hips against the desk to accommodate for his growing erection. "I knew you could do better."

"You're such a brat, Captain. You're not supposed to be enjoying this."

Levi jumped as Armin delivered an admirably hard smack. There was a gasp from behind. "Sorry, was that too hard? Are you ok?" Hands roamed over his backside, caressing the aching skin through the fabric of his trousers.

"No, it's fine," Levi mumbled, face burning. Fuck, I didn't actually expect him to hit me that hard! He's surprisingly good at this game…

"If you weren't such a bad soldier, we wouldn't have to do this." Levi felt a second, larger hand wander over his ass, making his cock throb painfully against the hard surface of the desk. Erwin's hand squeezed the abused flesh, dragging a moan from his lips. It stung, but in the best way possible.

"Are you ready for more? Or have you learned your lesson, Mr Ackerman?" the Commander asked.

"Fuck you and your fucking lessons!" Levi spat, eager for more punishments.

And he got his wish. For the next few minutes, Erwin and Armin alternated between delivering the spanks. Armin, it turned out, was a goddamn tease. As he gained more confidence, he started stroking Levi's back, ass and thighs with gentle hands, muttering sweet words about how Levi could avoid all of this, if he just promised to be a good boy and do what he was told.

To which Levi replied, "Like you? Are you a good little slut for your Commander?"

Perhaps he should tone down his language, but it was hard to think coherently in his present circumstances. His cock ached abominably, and his ass was longing to be abused in an entirely different way…

Armin heaved a sigh, similar to what Erwin had done earlier. He removed his soothing hands, making Levi's body tense in anticipation. Then his hand came down in a solid smack across his buttocks.

Levi couldn't take any more of this exquisite torture, or he'd come right here in his trousers. And that would be mortifying.

He tried to rise from the desk, but a strong hand pushed him back down.

"Have you learned your lesson? Will you do what you're told from now on?" Erwin asked sternly.

"For fuck's sake!" He squeezed his eyes shut, and ground out the shameful words. "Fine, yes. I'll be a good soldier."

If he'd simply said the safe word 'red', Erwin would have stopped immediately. But there was an inexplicable pleasure in submitting himself completely to his partner as part of the game.

The pressure of Erwin's hand on his back eased. Instead, two strong hands gripped his hips; turning him around and pulling him upright at the same time. Levi's legs wobbled from so long bent over the desk. He leaned back against it, gripping the edge of the wood.

Erwin enveloped him in his arms and kissed the top of his head.

"Are you ok Levi?" Armin hung back a few paces, eyes huge with concern.

"I'm fine," the Captain said gruffly. He cleared his throat. "You were really good."

"So were you," Armin gave an uncertain chuckle, fiddling with the sleeve of his long green coat. "Your disobedient soldier act is very convincing."

"I'm just playing my usual asshole self."

Armin's eyebrows rose. "Oh no, you're much nicer in real life! Or most of the time, at least." He shot him a little smirk before glancing away.

Well… fuck. Five months ago when they'd started this arrangement, Armin would never have had the courage to speak to Levi like that.

"Maybe you need to be punished next Arlert, for your insolence towards your Captain. What do you think, Erwin?"

His partner was wearing an echoing smirk to Armin's. He tightened his grip around Levi and said firmly, "We're looking after you tonight, Captain."

The Commander reached out a hand to Armin, and he hesitantly stepped forward to take it. Levi lazily slung an arm around the young man, pulling him close. "I guess you're too much of a good boy to enjoy even pretending to be in trouble," he teased.

An irresistible image of the young man bent over the desk came into his mind – that perky ass just begging to be spanked by his two superiors. But if receiving punishment wasn't Armin's thing, then Levi wouldn't push the topic.

Besides, so far Armin had done an admirable job of throwing himself into a dominant role. Levi couldn't wait to see more of his hidden skills.

Erwin nuzzled his neck. "Do you want Armin and me to continue this scenario in the bedroom?"

"Y-yes," Levi breathed. He swallowed, staring straight into Armin's inquisitive eyes. Could the young man tell how much power he held over him?

And soon he'd be completely under the mercy of the other two men…

Everyone discarded their boots as soon as they entered the bedroom. Erwin and Armin removed their green coats, and they divested Levi of his short brown uniform jacket. Then the librarian and Commander languished him with their attentions, as if he were their most prized possession.

Levi's wrists were tenderly secured to the bedposts while a silky blindfold was slipped over his face. His shirt was flung open to reveal the pale expanse of his muscular chest. They left the crisp white cravat hanging at his bare throat, somehow making him feel even more exposed.

Erwin, by now an expert at this sensual game, trailed kisses and feather-light touches over Levi's body. All his most sensitive spots – the insides of his arms, his neck, nipples, behind his knees, inner thighs, belly, feet, and more - were wholly at his partner's mercy. Erwin deliberately steered clear of Levi's straining erection under his trousers. He squirmed against his restraints, the exquisite torture being almost too much to bear.

The Commander's loving assault was accompanied by intermittent kisses from Armin. He massaged Levi's shoulders, murmuring sweet praises of what a good, well-behaved soldier he was. Levi was defenceless as their two hot wet mouths caressed his skin. His blindness and inability to move created a delicious heightening of his other senses.

Just as the ache in Levi's groin reached an excruciating level, the Commander seemed to decide to offer him some relief.

"The Captain's being such a good boy for us, isn't he? Perhaps he deserves a small reward… Would you like to climb on top of him?"

Levi heard Armin's assent, and then the man's weight settled on his hips. He cursed the blindfold, robbing him of this glorious sight of the librarian astride him. Would he look shy and innocent? Or perhaps that mischievous smirk from earlier played on those soft lips…

As it turned out, Armin didn't seem at all bashful in this moment. Under instruction from Erwin, he gripped Levi's bare waist and started grinding himself against his Captain.

Fuck… His cock throbbed in his trousers, begging for release. No doubt Armin could feel exactly what his movements were doing to him. He clamped his mouth shut, refusing to give the other men the satisfaction of knowing the full extent of his arousal. But when Armin ground even harder a traitorous hiss escaped his lips.

"You'll tell us when you're close, right Captain?" Erwin demanded, stroking the hair off Levi's sweaty forehead. "We can't have you finishing just yet."

Their game was to take him right to the brink of release, and then to withdraw. It was an activity Levi and Erwin enjoyed teasing each other with from time to time. Things were even more agonisingly pleasurable with Armin participating too.

After another minute, Levi was writhing against his restraints, bucking his hips against Armin's. Erwin muttered something to Armin, who stopped his movements. Levi groaned at the loss of friction.

Armin began stroking his chest instead, tracing the lines of muscles and scars with his fingertips.

"You're so strong… and such a good boy for sharing your body with us like this."

"Yes, you're our good, obedient soldier, aren't you Captain?" Hooking his fingers around Levi's cravat, Erwin claimed his partner's mouth in a long, possessive kiss.

After a few minutes, when the Commander seemed to think he'd cooled down enough, he decided to continue their onslaught.

"What do you think Armin, does the Captain deserve another reward?"

Levi strained his ears but couldn't catch the young man's whispered reply. It sounded like a question.

"You're in charge too. You decide what to do to him," Erwin said. Levi could imagine the amused smile on his face. His own lips quirked with affection for both of them.

"I'm – I'm going to touch you Captain. Is that ok?" Armin asked.

Levi had already consented to a list of sexual activities before they started. Armin didn't really need to ask his permission – he was supposed to be taking charge, after all. But it would take time for him to build up to Erwin's level of aptitude at these power games. Until then, Levi was happy to reassure the man.

In any case, it didn't fully break the immersive experience of their role-play fantasy. Armin's cautious behaviour quite suited the role he had fallen into playing – of a soldier being instructed by his Commander in how to dominate another man.

"Do whatever you want to me, Arlert," Levi growled in assent.

It wasn't long before his trousers were open and Armin's smooth hand was sliding up and down his cock. Levi's head pressed against the pillow, eyes squeezed shut behind the blindfold.

The bed dipped as Erwin shifted down towards Armin. "You're doing a great job. But I think you deserve some attention yourself, soldier."

The sounds of them kissing was soon followed by a rustle of fabric. Then Armin's grip on Levi slackened and low moans rose from his throat. His thighs, still straddling Levi's hips, made erratic movements. Levi conjured an image in his head of what was happening – Erwin with his large hand wrapped around the younger man's cock, mercilessly jerking him off.

"Do you want me to help you finish first, Armin? I'm sure the Captain won't mind waiting a little longer."

That fucking bastard!

Erwin knew just how to mess with his head and prolong his agony. First by offering to reward him, only to snatch the promise away moments later.

Levi held the power to use the safe word at any time he wished. The men would cease their torment, and focus on granting him blissful release instead. But that wasn't what he wanted. Denying himself now would make the pleasure infinitely more satisfying later on.

Armin seemed to have different plans from the Commander's suggestion.

"No, I think that's too cruel for Levi – I mean, the Captain. Is it ok if I rub against him?"

"You're such a nice boy, always thinking of others." The words might have sounded patronising spoken by anyone else. But Erwin's tone radiated genuine approval.

Once they'd moved from the study into the bedroom, Armin lost some of his dominating spark and had reverted into a role of letting Erwin tell him what to do. Which was fine – their plans for tonight were flexible, in order to allow Armin to stay within his comfort zone. If he didn't feel like sticking with the domineering role, they could work with it.

Levi knew Erwin was relieved to see Armin taking some initiative again. His own belly tightened, remembering the contrast of the young man's soft reassurances and hard slaps earlier.

Putting his idea into action, Armin lay on all fours atop of Levi; knees either side of his hips, and arms dipping into the mattress either side of his head. Levi fervently tried to picture it – Armin's flushed face, messy hair, and his open trousers revealing that pretty cock.

One of Armin's hands moved from beside his head down to between their bodies. It gripped Levi's cock briefly, before he pressed his own crotch against him and began stroking both of them at the same time.

"Do you enjoy Armin pleasuring you, Captain? Taking control of you?"

Levi whined in response; the sensations radiating from his groin were sinful. One of Erwin's palms ran possessively over his torso. He guessed the other one was busy petting Armin.

The motion of Armin's hand stuttered after a while – he'd never been able to manage this activity for long. He made a little growling noise, clearly frustrated. Levi's restrained hands longed to lend some assistance.

"Commander, would you assist us?" Armin's voice was brisk with impatience. It made Levi's cock twitch.

"Of course, what do you need?"

Armin didn't reply. But his hand moved away and moments later was replaced with one that was larger, and slightly cooler. Erwin's. With an electrifying jolt, Levi realised the younger man was guiding the Commander's hand over their cocks. Showing him exactly what to do.

Erwin wasted no time in obeying Armin's silent instruction. His bigger grip was more suited to this purpose, sliding over their sensitive flesh with practised ease. Soon both men were panting and making breathy little groans.

Levi was so close… He wanted to come right here and now, with Armin gasping over him, and his partner's hand pumping their cocks in unison. Erwin wouldn't mind – they'd broken out of scenarios before, it wasn't a huge deal.

But then tantalising thoughts of how powerful the delayed gratification would be flooded his mind…

"Fuck, I'm close," Levi spat out.

Erwin's hand released its grip and Levi fought to hold back a whimper of frustration.

"Armin? Do you want me to finish you off?"

This time the whine burst unbidden from Levi's throat. The thoughts of that little brat getting to come while he was forced to lie under him…

It was pretty fucking hot.

Armin released a low chuckle, and once again declined Erwin's offer. "No it's fine. I'll wait for later."

"The Captain's been such a good boy for us, I think he's learned his lesson." Erwin lay down beside Levi, stroking his aching bound wrists.

"I think he deserves a proper reward this time. No more teasing." Armin's voice was deep and demanding, with barely a trace of his hesitation from earlier. "Perhaps we can let him decide?"

"Good idea. How do you want us to reward you, Captain?" Erwin leaned close, hot breath tickling Levi's ear. Lowering his voice he murmured, "Tell us what you want, darling. Anything."

His partner's warm, inviting tone lulled Levi into a dangerous state of weakness. He wanted nothing more than to submit fully under these two men – to be turned into a whimpering, sobbing mess between them.

The words were out of his mouth before he could stop them.

"I want you both to fuck me."

Armin

Levi's request was met with a long silence from Erwin. His body stiffened, brows furrowed in contemplation. Armin wanted to do something to ease the tension. But he was still reeling from shock himself.

Levi wants both of us to top him? But we've never discussed me doing that before…

Feeling self-conscious, Armin did up the front of his trousers, since it didn't look like they'd be resuming their session straight away. Or perhaps not at all.

Levi looked completely debauched from their games - bare chested, trousers open, hair wild. His usually neat cravat hung askew on his neck, like a mockery of his former dignity. Only moments ago, he'd presented a tantalisingly sexy aura. Now he simply looked vulnerable, with his pale body exposed, arms taut as they strained against their restraints, and mouth gulping in panicky breaths.

"Red. Can you untie me?" he pleaded, using their safe word.

Snapping out of his reverie, Erwin untied one of Levi's hands. Armin moved up on the bed to tackle the other one. When Levi was free, he pulled the blindfold off his face, not bothering to untie the knot at the back. Then like Armin, he re-fastened his trousers.

He faced his partner, expression etched with apology. "Forget I said that Erwin. I wasn't thinking properly."

Armin's mind was still whirling. Why would Levi even want me to top him? He's never mentioned he was interested in it before. Is Erwin angry at him? Is he angry at me? Does this request put us in competition, like I'm invading Erwin's role or something?

Armin had never considered himself capable of being dominant in a sexual situation before. With Jean, he'd always let the other man take the lead in their encounters. He didn't expect other men would ever want him to play any sort of dominant role. Until he met Levi and Erwin, that is.

Topping didn't necessarily mean being dominant, although the two roles could work hand in hand. Knowing Levi desired him in this way made his stomach flutter. But was it a point of contention between him and Erwin? Armin dearly wished the man had kept it a secret.

The Commander turned his head to pierce Armin with an intense gaze. His features suddenly looked drawn, the lines of his face more pronounced in the flickering candlelight. He exhaled loudly, the sound full of weariness.

"Levi, you know I'm not wholly against the idea. But neither am I comfortable with it just yet. And it's not fair on Armin either - this is something we'd need to discuss properly first."

"I'm sorry, I shouldn't have asked for it. I didn't mean to put you on the spot." Levi rubbed at the red marks on his newly freed wrists, voice raw with emotion.

Erwin leaned over to the bedside cabinet to grab a bottle. He uncapped it, squeezed out some lotion and started rubbing it into Levi's sore wrists. His motions were gentle and efficient, as if well practised at this sort of care.

A rueful smile tugged his lips. "It's my fault too. I walked into a trap by saying you could ask for anything."

Armin felt like an intruder to this intimate moment. Teaming up with Erwin to tease and pleasure Levi had been an incredible experience. But he wondered if an invisible line had been crossed, and his presence was no longer welcome.

"Do you want me to leave?"

Both men glanced over at him in surprise and said "No!" almost in unison.

"I was taken aback by Levi's request. But it doesn't need to get in the way of the rest of tonight," Erwin said, seeming to have regained his composure. "And maybe we can discuss it another time. That is, if you're interested, Armin."

His first reaction was to say no. But so far he'd never regretted being honest with these men when it came to intimate matters.

"I am interested… but not if it causes any problems between you two. I don't want to overstep my role in this arrangement."

"You're always thinking of others, aren't you?" Erwin placed his hand over Armin's, his thumb tracing a light pattern on his wrist. He appraised him, expression full of approval. It made the younger man's pulse quicken.

"Sorry if I put you under pressure, Armin," Levi said, without a trace of his usual guardedness. A smile ghosted his lips. "Maybe you were just too good at the whole dominating act."

Armin glanced at Erwin – was he jealous at his partner's admission? But the man surveyed them with a crooked smile before leaning over to first kiss the top of Levi's head, and then Armin's.

"I agree with Levi; you've got an instinct for taking charge. You'll be bossing me around next."

The librarian laughed at the absurdity of this statement. Then he realised neither Erwin or Levi looked displeased with the notion.

"Don't worry, we won't start calling you Commander just yet," Levi teased, sliding his hand into Armin's.

The tension from earlier had completely dissolved. When Levi said he was thirsty, Erwin fetched a glass of water from the kitchen. His expression was thoughtful when he returned.

"I might have a compromise for your request Levi."

"Well, don't leave us in suspense. What is it?" Levi's words were edged with his old snark.

"We were originally planning for me to top you next, and for Armin to participate like he usually does. But what if Armin helps me to prepare you? More directly, I mean."

"You mean finger me." Levi's bluntness didn't conceal his interest. "What do you think, Armin?"

Is this a bad idea? Fingering isn't quite the same as topping him, but it's still extremely intimate…

"I'm fine with it. I wouldn't suggest it otherwise," Erwin assured him, sensing his concern. "I'll help you out, of course. What do you think?"

Heat flared in Armin's groin as images of Levi splayed out under him filled his mind. Watching Humanity's Strongest mewl and squirm in pleasure the way he did when Erwin was inside him.

But it was the enthusiasm in the Commander's voice, and the expectant look on the Captain's face, that made up his mind.

Heart hammering, he said, "Alright… I'll give it a go."

Erwin pulled both Armin and Levi close, so they were caught in a three-way embrace. "Great! Let's reward our Captain then. We've teased him enough tonight."

"Are you ready for Armin to have a go now, Captain?" Erwin asked.

Levi lay completely undressed on the bed, face flushed from his partner's ministrations between his legs.

"Y-yes. If he still wants to."

Armin nodded, pushing back the intrusive fears that he wouldn't be able to match up to Erwin's prowess. He instead focussed on his desire to give Levi as much pleasure as possible.

He allowed Erwin to guide him between Levi's legs, which were shaking slightly. Erwin squeezed his thigh. Armin followed suit and gripped the other one in what he hoped was a reassuring gesture. He traced circles on the skin with his thumb. It was hard to decide where to look – he was acutely aware of Levi's vulnerability being spread out like this to someone new.

I'm the only other man to touch Levi like this… He's putting so much trust in me.

Armin recalled how Levi and Erwin had acted when they'd performed this act for him. Summoning his courage, he properly absorbed the sight of Levi's glorious body laid out before him. The man's muscles tensed under his scrutiny. Reassuring words poured from Armin's mouth without thinking.

"You look so beautiful, Levi. I can't wait to make you feel good."

Levi didn't answer. His eyes focussed on a spot on the wall behind Armin. But his body relaxed and his legs stopped trembling.

Under Erwin's guidance, Armin slicked his fingers with oil and teased Levi's entrance. He was nervous to go any further, however.

Am I really capable of doing this? What if I hurt him? Surely it would be better if Erwin just took back over and-

"Please… Armin… I want you inside me."

Armin's heart did a flip. The Captain had never begged him like this before, with such candid rawness. This did not seem like the soldier who'd cut down countless titans in the past, the thug who had dominated the Underground's criminal world, the man who instilled dread and awe throughout Paradis.

And yet, there was an undeniable strength for such a formidable man to admit his desire so blatantly.

Levi Ackerman knew exactly what he wanted. And Armin had the power to give it to him.

With a start, he recalled Erwin's presence. He glanced at the larger man to see his reaction to his partner's pleading request.

"Go ahead Armin. Just enter very slowly, and give his body time to adjust." He rubbed Armin's back soothingly with one hand, while holding Levi's hand with the other.

When Armin's full finger slid in, he probed around like Erwin explained to do. He almost pulled his finger back out when Levi yelped and bucked his hips.

"Fuck, that's it! Keep touching there."

It wasn't long before Armin had three fingers inside, and under both men's instructions he began pumping them in and out in a steady rhythm.

"Ahhh…. Armin," Levi whimpered, writhing against his fingers.

Armin was suffused in a blanket of affection and intoxication. And then alarm bells rang in his head, dousing him with an icy warning. Was it dangerous to feel such an intimate connection to Levi?

Maybe slipping back into the role-play game will make this feel less romantic…

"You're so tight Captain," he said gruffly.

Erwin caught on immediately. He was lying beside Levi, surveying the action below while he lazily stroked the man's leaking cock. "You look so good fucking yourself on Arlert's fingers. I bet you'd love to have his cock pounding into you, wouldn't you?"

Levi's eyes shimmered with overstimulation. "Yes," he whined.

"Well, if you keep being a good boy for us, maybe Armin can fuck you another time."

Armin's cock twitched at the prospect. But he knew the words were simply dirty talk, aimed at stimulating Levi. The matter still needed to be discussed properly between them.

"Fuck, I'm close," Levi panted.

Armin slowed his movements, looking to Erwin for guidance on what to do next.

"Do you want me to fuck you, Captain?" The Commander demanded.

"Yes… please…" Levi's voice was barely above a whisper. He murmured something else which Armin didn't catch.

Erwin's mouth tilted in a frown. For a moment, Armin feared Levi had made another request that his partner wasn't comfortable with. But then the man smirked.

"Arlert, your Captain has a suggestion - to reward you for your hard work tonight. He wants to suck you off while I fuck him. Do you want to try that?"

The suggestion was shocking in its bluntness. But something else struck Armin. By speaking crudely and calling me 'Arlert', is Erwin trying to distance himself emotionally from me too?

He searched each man's gaze in turn, making absolutely sure this was something they both wanted.

"Yes, let's try that," he agreed.

After a brief discussion over what position would be best, Erwin and Armin undressed. Levi got onto all fours, while Armin sat in front of him. This would allow Levi control over the pace at which he gave oral. Erwin stood at the edge of the bed, right behind Levi's ass.

They tested out first if this position was comfortable for Levi. Erwin held onto his hips while he lowered his front half so his forearms were resting on the bed either side of Armin's legs. Now Levi's face was inches away from the other man's cock. Supporting himself on one arm, he used his free hand to slide up and down it until it was fully erect.

Armin squeezed his eyes shut as the Captain's hot mouth enveloped the tip, and gradually worked its way further down. He knew Erwin was watching hungrily from behind Levi. That made the whole thing even hotter. He threaded a hand through Levi's soft hair and murmured encouragement. Due to his more manageable size, Levi was able to take more of Armin than he could with his partner.

"You're such a good boy, looking after Armin like that," Erwin crooned. Levi made a whimper in his throat at the praise. "Do you want me to fuck you now?"

Levi popped his mouth off Armin, wiping his lips with the back of his hand. "Yes, but take it slow. I don't want to choke."

Erwin entered him carefully like instructed. Armin watched as Levi's face scrunched up first with slight discomfort, and then with pleasure. He panted over Armin's lap, warm breath teasing his wet cock.

Once Levi adjusted enough and they reached a regular rhythm, he dipped his head back down to resume his previous efforts. He moved slower this time, trying to match the bobbing of his mouth to Erwin's thrusts.

Armin closed his eyes again, unable to take in the overwhelming sight. But his thoughts prickled at him. You need to make the most of this. You might never get to experience something like it again!

With great effort, he opened his eyelids. The lascivious motion of Levi's mouth over his lap almost forced them closed again. Behind him, Erwin was panting with his own pleasure, greedy eyes absorbing his partner's efforts to satisfy their guest.

Each time Levi moaned around his cock, the vibration shot sparks through Armin's body. He struggled to regulate his own breathing.

"That feels amazing Captain," he encouraged him.

"You're such a good little slut for us, taking our cocks so well," Erwin growled.

Levi's face was dripping with tears, saliva, and probably Armin's precum. Knowing how the man felt about mess, Armin wondered should he ask if he wanted to stop. Even though Levi was in control of the pace, he didn't want him to overexert himself.

"Take a break if it's too much for you, ok?" he pulled Levi's fringe off his sticky forehead, caressing his dark hair.

Soon afterwards, the man did just that. "Red. I need a second," he huffed, face red and shiny.

Erwin stopped his actions and rubbed along his partner's flanks. "You did such an incredible job, darling."

Armin scooted over to grab a towel from the bedside cabinet. Levi accepted it gratefully. "Thanks Armin." With a grimace he wiped at the mess on his face. When he finished, he said, "I'm not sure I can keep that up any longer."

"Do you want to try something else?" Erwin asked.

The three of them decided on a new position. Once Levi was ready, they moved into it – with Armin lying on his back, Levi on all fours over him, and Erwin kneeling behind his partner on the bed. This time Erwin picked up a brisker pace than before.

Levi used one hand to support himself, while the other stroked Armin's cock beneath him. He couldn't keep this up for long, and soon had to brace himself on the mattress with both hands.

"Touch yourself, Arlert," the Captain ordered. "Show us what a slut you are for your superiors."

Erwin gave his partner's backside a light smack. "I think you're forgetting who the real slut is here, Captain. You're the one who begged to be in between us."

Armin snorted out a laugh at Levi's indignant expression. He reached up a hand to stroke the man's swollen cock, while touching himself with the other.

"Armin…" The single word escaped Levi's mouth in a gasp, before his face scrunched up in ecstasy at the double stimulation.

He was the first to come - cheeks glistening with tears, whining out their names in a long, guttural plea. Hot splatters of cum dripped onto Armin, and a few moments later he came too into his own hand.

Through the crashing waves of his orgasm, he closed his eyes, captivated by Levi's desperate whimpers and the slap of flesh on flesh as Erwin slammed into him with relentless force.

"Are you our little slut Captain?"

"Yes, I am! Please… Commander…"

With a low growl, Erwin finished inside his partner. Levi released a feeble moan and collapsed on top of Armin, his body wrecked with convulsive, breathless sobs.

He knew that the tears were from overstimulation, not anguish. Still, Armin's heart tore in half to see his Captain so fragile and broken. He wrapped his arms around the man's strong back and offered soothing reassurances and praise.

When Erwin pulled out of Levi, he grabbed the towel and moved up on the bed beside the other two men. He smiled gratefully at Armin's efforts to care for his partner.

"You were so good for us," Erwin told Levi, rubbing his back. "Why don't we get you cleaned up now?"

A few minutes later, after cleaning up and pulling on pyjamas bottoms, the librarian, the Captain and the Commander cuddled on the bed together. Levi nestled into his partner's embrace, while Armin's arms cradled him from behind.

"You were both great, thank you," Levi croaked out.

"Was any of it too much for you?" Armin asked in concern, squeezing his shoulders.

"Don't worry, I'd have used the safe word if I wasn't enjoying it."

"How about you Armin? Would you prefer us to tone anything down the next time?" Erwin asked, reaching an arm over Levi to include the younger man in his embrace.

Is he referring to his dirty talk about me fucking Levi? "No, it was all fine," Armin assured him.

Levi tensed between them, shoulders hunched. His sobbing had subsided, but he was still trembling as if from cold.

Erwin pulled his partner in tighter. "What do you need darling? Something to eat or drink? A massage?"

"No, I'm fine. You should go finish up those meeting notes you were working on earlier."

"Never mind about my work Levi. You're more important."

"Erv, with how busy you are lately, I wouldn't have blamed you for cancelling our plans tonight. I really appreciate you making the time for me. And I honestly just want to wash, I'm too tired for anything else." Levi turned his head to glance at Armin behind him. "How are you feeling? Do you want to shower here before you go?"

"Oh no, it's ok. I don't want to take up any more of your night."

"Are you sure you don't want tea, or some food?" Erwin insisted. The man looked exhausted, barely able to keep his eyes open. "Tonight was intense for you too. We don't want to kick you out without looking after you."

"Do you want a bath?" Levi suggested.

Armin had been ready to protest again that he was fine. But Levi's offer was too tempting to refuse. He'd only used the bath in Erwin's quarters once before. And he hadn't been in the best mindset to fully appreciate it at the time.

"Actually yes, that'd be nice. Unless you were thinking of using it?"

Erwin glanced between both men, a mischievous expression playing on his handsome, tired features.

"Why don't you have a bath together? That'll give me a chance to finish up my work. I could give you both a massage afterwards too?"

As amazing as this sounded, Armin held back a laugh. There's no way Levi's going to agree to this!

Indeed, the Captain was silent for a long moment. Then he shrugged his bare shoulders. "Sure. What do you think, Arlert?"

Notes:

Alternate titles for this chapter were: 'Between my Librarian and Commander'; and 'Who Do You Think The REAL Slut Is?' (based on Erwin's 'who do you think the real enemy is?' line from canon 😆)

I tried something new this chapter by using little timeskips between the smut, because there was so much I wanted to squeeze in! What did you think of it in the end?

Next time we get an aftercare bath scene between the Librarian and the Captain. But don't worry, there is something very special coming up for our Commander too. He will finally get the attention he deserves… (Also, spoiler Arlert for more dom Armin!)

Until then, THANK YOU for sticking with this story!
