Notes: Here's Part 2 of the Second Night! Hope you enjoy it :)

Previously: Armin, Levi and Erwin kicked off their second night together with some intense kissing, cuddling, and Erwin showing off his oral skills. But now Erwin wants to focus his attention on his partner's pleasure… with Armin's help, of course.


Chapter 13: The Second Night (Part 2)

Levi

Levi watched as Erwin murmured seductively in the librarian's ear. A sly, crooked little smile danced across Armin's delicate features.

"What are you brats whispering about?" he grumbled, without any real bite to his words. He knew what Erwin was proposing to Armin – they'd discussed the matter earlier. But his stomach twisted with self-consciousness now it was time to actually go through with it.

"Why don't we show you?" Erwin pierced him with an appraising look. Then, adopting what Levi called his 'Commander's voice' he demanded, "Captain. Move into the middle of the bed."

"Oh, so you want to be the Commander now, do you?" Levi sneered. It was all part of their usual game – Levi would push Erwin's dominance at first, before completely giving into it later on.

This type of sexual play used to make Erwin uneasy. At his core, the man was a complete gentleman. He never wanted to hold his elevated military rank over Levi. In his mind, they were complete equals.

But once he discovered how much Levi enjoyed these games, Erwin was determined to satisfy his partner in any way he could. And as it turned out, he was actually pretty damn good at playing an exaggeratedly dominant role in the bedroom.

"I'm always the Commander," Erwin admonished his lover. He stood up, looming over the other two men perched on the end of the bed. A devious smirk lit up his handsome face as he surveyed them.

Armin turned his head away and fiddled with the duvet cover. Levi's chest tightened. The man isn't used to these games. Maybe we should tone it down?

"Arlert, is this type of talk making you uncomfortable?"

Armin glanced at him. To Levi's surprise, he was smiling bashfully. "No, it's fine. It seems kind of fun actually."

"This won't be a proper role-play, we'll keep it light," Erwin explained. "Just tell us if anything makes you uncomfortable."

When the librarian nodded, Erwin turned back to Levi with a heavy sigh. "Captain, I thought I told you to lie down in the middle of the bed?" His words dripped with authority.

Damn it, the bastard knows what his Commander's voice does to me!

Levi grumbled some more, but found himself powerless to disobey his partner's commands. The next part of the night would go a lot smoother if he trusted Erwin to take charge. A concoction of excitement, nerves and impatience bubbled in his stomach, making him jittery as he moved up to the top of the bed.

"Do you want to lie down beside Levi?" Erwin asked Armin, voice lowering to a soft and inviting tone. It was more of a suggestion than an order.

Armin scrutinised Levi, his face solemn in the flickering candlelight. "Are you ok with me taking part in this? And um… do you want me to play along with the game too? Should I call you Captain?"

"Call me whatever you're comfortable with," Levi said quickly. "And the same goes for what you call Erwin."

Armin nodded, those beautiful ocean-blue eyes wide with sincerity. "So, Levi… do you consent to me taking part?"

Embarrassment washed over Levi at this stiff formality. But a part of him also admired Armin's directness.

"Yes, I fucking consent Arlert," he grumbled, rolling his eyes at the ceiling. "But thanks for asking," he added in a mutter.

Erwin's eyes gleamed as they flickered eagerly between the other two men. He was on the verge of fulfilling one of his biggest threesome fantasies - teaming up with another man to pleasure his partner. Levi had been just as enthusiastic by this prospect when he and Erwin discussed it during the week.

And so far, Armin looked eager to participate, and Erwin wasn't struck by stage fright like he'd been last week. Things seemed to be off to a promising start...

Except for the fact that Levi's stomach was writhing like a den of angry snakes.

He gritted his teeth, mentally slicing through the doubts that were threatening to swarm him. No, he refused to let his nerves overwhelm him like last time.

The librarian was already crawling over the bed to settle beside Levi, while Erwin positioned himself on Levi's other side. He was forcefully reminded of last week, when the three of them had lain side by side.

Only this time, I'm the one in the middle, not Armin...

Levi focussed on his breathing, trying to calm his racing pulse. His fists tightened against the smooth bedsheets.

"Will you let us take care of you, Captain?" Erwin asked, voice thick and sweet as honey. He leaned over and brushed his lips on the top of Levi's head. The touch tickled pleasantly on his scalp.

When Erwin pulled back, Levi turned to face Armin. The man was still smiling shyly, his features shining with anticipation.

Levi's stomach twisted in an entirely different way. Fuck it! I want to give this a go - both for my own sake, and for Erwin's. And Armin's, too.

"Fine, go ahead," he said gruffly.

His heart almost stopped when Erwin climbed on top of him, and swooped down to capture his mouth in a hard kiss. Levi closed his eyes, actively trying to forget about Armin's presence so he could relax.

Luckily, Erwin managed to work his usual magic. Forget about his Commander duties, the man deserves a fucking medal for his work in the bedroom…

This dominating approach was exactly what he needed. Caged under Erwin's body, he saturated Levi's senses – from his strong, calloused hands pinning him to the mattress, to the subtle scent of his sandalwood cologne, to the hot mouth on his own tasting of peppermint. It sparked a fire deep within Levi, making it impossible to think about anything other than his immediate physical needs.

Once, this would have all been too much for him. The level of trust and vulnerability needed to be intimate had been an insurmountable wall, barricading him from getting romantically close to anyone.

But when he joined the Survey Corps, Erwin had patiently coaxed him into sharing more of himself. And now, years later, he never felt safer than when he was enveloped by Erwin's comforting presence. The man's persistent friendship, and later love, had changed his life forever.

Within minutes, Levi had surrendered himself completely under his control. A raging inferno was consuming all his fears and reservations, until only a searing passion remained.

It's such a relief to be able to let go… to trust someone enough to take charge…

Skin itching for more contact, Levi helped Erwin shrug out of his shirt, and pulled off his own shirt and trousers. He kept his eyes shut – pretending it was just a normal night between the two of them…

Erwin's hand slid beneath his underwear. Levi's eyes snapped open, gasping.

And that's when he noticed Erwin's free hand was entwined with Armin's. The young man was lying on his side watching them, lips slightly parted. Right now his eyes were fixed on Erwin's large palm relentlessly stroking Levi's cock.

The cosy intimacy shattered, like a teacup smashing on the floor. His fingers spasmed with the urge to push Erwin's hand away and cover himself up. But the captivated look on Armin's face halted his movements.

Their eyes met.

Armin flinched backwards, eyes wide, breath quickening. Mortification doused Levi like an icy hailstorm.

Biting his lip, Armin mumbled a squeaky, "hi."

Levi's nerves thawed and he let out an impulsive snort of laughter.

"Hey yourself, brat."

The edges of the librarian's mouth quirked. His eyes softened, losing their panicky look. "Can I –" he began, but stopped and glanced between the two men, seeking permission. "Can I touch you, Captain?"

Fuck! What exactly does he mean by touching?

After gulping in a steadying breath, Levi replied on the exhale, "Yeah, alright."

Grinning, Erwin pulled off Levi and lay on his other side, giving Armin more room. The young man's expression was almost comically serious as he skimmed a hand along Levi's upper arm, and then slowly slid it over his bare chest and stomach. Erwin watched on greedily, while he resumed his motions on Levi's cock.

"You two look so good together," Erwin said thickly.

His obvious enjoyment eased some of the tension in Levi's body. But while Armin's feather-light touches were pleasant, they were more of a tease than anything else.

"That's so good Arlert," he murmured, hoping to bolster the man's confidence.

It worked like a charm. Armin's touch grew bolder, with both hands now roaming over Levi's chest, rubbing the nipples and tracing the planes of his taut muscles with curious admiration.

The combined sensations of Armin's soft palms gliding over his flesh, and Erwin's firm motions on his cock, forced Levi to throw his head back against the pillow. His eyelids drifted closed as he soaked up this double attention.

Erwin's right, there's definitely benefits of having another man in the bedroom…

"Are you ready for more, Captain?"

Erwin's deep rumble sent a fresh spark of excitement through Levi. Seriously, the power that man held in his voice alone was nothing short of dangerous.

Armin was similarly affected, Levi noted with amusement. His hands slowed their exploration, and he bit his lip and furrowed his brow.

Levi nodded to his partner, giving assent to continue.

"Armin," Erwin said, and the man's eyes widened as he turned to face him. "Can you help keep the Captain relaxed while I prepare him?"

"Oh – of course," he stammered. He swallowed, then repeated more firmly, "I'd be happy to, Commander."

"Good boy," Erwin said, shooting him a kind smile. Armin grinned and glanced away. As always, words of praise made him glow like the sun reflecting off water.

Levi smirked. I wonder what other secret kinks he's hiding… and would he be willingly to explore them with us?

But his amused curiosity vanished as Erwin grabbed the bottle of lubricant from the nightstand, and settled between his legs. Those familiar large hands tugged off his underwear and then rested on his thighs.

"You're being so good for us Captain," Erwin murmured, low and soothing. "You look incredible spread out like this for me."

Fuck. It might have been entertaining to watch Armin turn into a blushing mess with Erwin's praise. But Levi was defenceless against the very same trick. He wanted nothing more than to melt under the Commander's irresistible charms.

And yet, his fears were clawing their way back, twining through his thoughts like vines.

What am I afraid of? Levi asked himself viciously. Armin's already seen me getting fucked last week!

But this time was different. He'd be right beside them the whole time, and actively participating.

Did Levi truly want this? He'd enjoyed everything he and Erwin had done with Armin so far. But this level of intimacy felt like it was crossing a boundary. All the shining excitement and hopes he'd built up for tonight faded away, scrubbed raw by his doubts.

As much as I want this for Erwin's sake, I'm not sure I can go through with it.

"We decided that Levi wouldn't prepare himself earlier," Erwin was explaining to Armin, "So you could get an idea of what full anal preparation is like."

Yeah, and I'm seriously regretting that idea right now…

Levi opened his mouth to speak, but only air came out of his tight throat. A trace of that old panic seeped into his bones. He hadn't felt such trepidation over intimacy since the start of his relationship with Erwin.

"Darling, are you alright?" Erwin asked. The commanding tone from earlier was replaced with concern. He leaned over to squeeze Levi's hand.

Levi didn't answer. He avoided both of their gazes, trying to translate the chaos inside his head into words.

"Just tell us what you want," Erwin urged.

"Do you want me to go?" The pained disappointment in Armin's voice snagged at something inside of Levi.

He turned his head on the pillow, staring into those mesmerizing eyes - pupils huge and dark, swimming in a clear blue ocean.

"No," Levi croaked out. And it was the truth.

Armin's furrowed brow relaxed. But he still looked confused. "Is there anything I can do? Or would you prefer if I just watched?"

The kind sincerity in his tone jolted Levi. But he knew it was all just for Erwin's sake. By pleasing Levi, Armin was no doubt seeking to garner more praise and attention from his charming Commander…

And after all Levi's teasing and tormenting of him, could he really blame the young man for his preferences?

But Armin was staring determinedly at him right now, not Erwin. As if he'd forgotten about the Commander entirely. His hand tentatively stroked Levi's forearm, above where Erwin held his hand.

It's like those early days with Erwin all over again. But this time I'm not the angry, mistrustful soldier I used to be. This time I'm not ashamed of my desires.

And I can trust Armin. He's already proven he can be discreet, and he's been nothing but respectful the whole time we've spent together.

Besides, Armin's unrestrained enjoyment in watching Levi and Erwin fuck last week had been beyond gratifying. And that intent, glazed-over look on his face earlier as he observed them again…

Levi made his decision. Let's give this gorgeous little brat something else to drool over. After all, he's here now, why not make the most of him?


Armin

"Is there anything I can do? Or would you prefer if I just watched?"

Armin was desperate to help the man relax and enjoy himself. He wanted to repay Levi and Erwin some of the pleasure they'd selflessly offered to him.

Levi didn't respond. He studied Armin's face as if trying to read his mind.

Despite the Captain's assurance that he wanted Armin to stay, panicky thoughts swirled around his head like a swarm of energetic bees.

Is he telling the truth? Or is he only going along with this for Erwin's sake? And why is he staring at me like that?!

"Should we try something else?" Clutching his partner's hand, Erwin ran his thumb in soothingly circles over the skin.

Armin returned Levi's intent gaze. His eyes were dark with unfathomable emotion that the librarian couldn't decipher. Would he ever understand the Captain? Or was Erwin the only person he'd ever trust with the depths of his soul?

"No," Levi replied, his voice suffused with renewed certainty. He pulled his hand out of Erwin's. "Let's give this a go."

Then a strong arm shot out to grip the back of Armin's head. The breath caught in his throat.

"Come here," Levi murmured, pulling his face down.

Armin allowed himself to be guided down to the kiss. His heart fluttered in his chest like a bird trying to escape. He'd kissed the Captain before, but never with the man completely undressed. Somehow that simple fact changed the dynamics completely.

He braced a hand on Levi's chest as their mouths met. To his surprise, the heart under his hand was pounding as fast as his own.

He's so nervous… Will I really be able to help him relax?

Armin resolved to give it his best go. He focused his full attention on Levi, pushing aside his curiousity as to what Erwin was doing below them. Their lips and tongues clashed in a fervent battle, before Armin yielded to Levi's dominance. His hand flexed through Armin's hair, holding him in place securely, but not forcefully.

Armin trailed his fingers in spiral patterns over Levi's chest and abdomen. They finally broke apart when Levi made a little gasping noise, and Armin pulled back to let him breath.

Glancing down at Erwin, he saw his hand was extended between Levi's legs. He couldn't see exactly what he was doing, but from the way Levi's mouth twisted in a grimace, he could guess.

"We're both going to make you feel so good, Captain." Erwin's eyes were hazy, boring into the other two men with undisguised lust.

Armin's pulse stuttered. How many times had he dreamt about the Commander looking at him like that?

Trying to emulate Erwin's performance, he swept his palm appreciatively over Levi's chest, and said, "You look so beautiful, Captain."

Levi flitted his gaze away from both of their ardent stares. His lips twitched furiously, like he was trying not to smile.

"You manipulative little brats," he grumbled under his breath.

Satisfaction trickled over Armin at Levi's evident pleasure. Then he recalled how the men had reacted well when he'd seized some initiative last week. Could he try that again now?

Swallowing back his fear, he dropped his gaze over Levi's chiselled chest and flat stomach, and down to his neglected erection. "Do… do you want me to touch you… there?"

Heavy silence engulfed the room. Armin's stomach clenched, preparing for the other man's teasing onslaught over the timid phrasing of the question.

"Y-yeah." The simple word escaped Levi's mouth in a rasp, surprising Armin.

His delight was swiftly smothered in a tide of nerves. What if I'm bad at this? The two of them have so much more experience than me… Why the hell do they even want me here at all?

The chasm between his own meagre skills and Erwin's seemed laughable. Who was he to try to assume the Commander's place by pleasuring Levi? Surely he'd only embarrass himself in the attempt…

Stop pitying yourself! I'm not Erwin, and I never will be. But judging by how Levi kissed me just now, he's definitely attracted to me. So stop doubting yourself.

Painfully aware of the two pairs of eyes burning into him, Armin slid his hand down Levi's torso and stomach. It had been months since he'd last touched a man like this. But Jean had always enjoyed their encounters, so surely he wasn't awful at it?

He wrapped his hand tentatively around Levi's cock, stroking him with gentle motions.

"Harder," Levi breathed after a few moments. He reached down and grasped Armin's hand; tightening his grip and demonstrating a steady pace.

When he let go, Armin's grasp went slack. The strange intimacy of this gesture left him paralysed. It had been delivered with the Captain's usual forthright manner, as if he'd been adjusting Armin's grip on a sword during a training session.

Cautiously, Armin resumed his task, copying the technique Levi had shown him.

A sigh hissed from Levi's lips. "That's it, Arlert."

"You're so good at that, Armin," Erwin groaned. His hand continued moving between Levi's legs, out of Armin's sight. "How do you like being the centre of attention, Captain?"

Levi didn't need to reply – the rough little moans he was making were answer enough. Seeing the gruff, formidable Captain reduced to this state was surreal. And knowing he'd contributed to it sent a surge of self-satisfaction through Armin.

He imagined being in Erwin's place, expertly fingering Levi until he made those exquisite noises for him too. But given the man's nervousness only a few minutes ago, he didn't dare suggest something quite so intimate.

However, there was something else he was willing to ask for…

"Can I…" he searched around for a polite way to say this. Then he recalled how Erwin has phrased it earlier. "Can I use my mouth on you?"

The Captain's eyes flew open. He glanced in surprise at Armin, and then Erwin. He swallowed.

"Y-yeah, alright," Levi said, sounding more shaken than Armin had ever heard him before.

"Do you want me to demonstrate first?" Erwin asked. His eager tone fractured the calm, controlling act he'd maintained up until now.

It must be exhausting for him to always play the Commander. Surely he doesn't do this around Levi all the time… does he feel pressured to keep it up for my sake?

Armin nodded, grateful that he wouldn't need to go into this blindly. He hadn't exactly been taking notes while Erwin was giving him oral earlier – he'd been too overwhelmed to pay attention to the specifics of what he was doing.

As Erwin lowered his mouth onto his partner, Armin was struck by a realisation. This offer was a typical act of kindness from Erwin; an acknowledgement of Armin's innate shyness and limited experience.

But was it also a sign of Erwin's dominance, a reminder to Armin that Levi belonged to him? Was he staking his claim with this gesture, marking his ownership?

If he was, Armin understood. Jealousies were a risk in this sort of arrangement. If Levi and Erwin needed to assert their relationship in front of him, he couldn't exactly blame them.

And he was thankful for Erwin's demonstration. He watched it with a voyeuristic thrill - his mouth sliding up and down Levi's length, hand grasped firmly at the base. He moved slower than Armin expected, maintaining a careful, steady rhythm. His cock twitched in memory of Erwin between his own legs earlier in the night.

Indeed, Levi seemed to be enjoying the act just as much as Armin had. He writhed against the bed, fisting the sheets beneath him.

After only a minute or two, Erwin pulled off and swiped his wet mouth with the back of his hand. Seemingly unperturbed by the fact that he had just sucked his boyfriend off in front of another man.

"Just take your time Armin, and stop whenever you need to," he said.

Reassured, Armin shifted down the bed so his face was level with Levi's hip. Erwin was still between his legs, an expectant smile consuming his face as he glanced between the other two men.

Not that size really mattered to Armin, but he noted that Levi was smaller than Jean. Which would hopefully make this task a bit less difficult.

But the two pairs of greedy eyes tracking his every move made him painfully self-conscious.

How the hell did Erwin do this so casually, and make it look so sexy?! My attempt is going to be pathetic in comparison…

Levi bucked his hips slightly, a seemingly involuntary movement. But it indicated to Armin how much the man wanted this.

Emboldened, Armin adjusted himself so he was reasonably comfortable, and leaned his head over Levi's cock. It glistened with a coat of Erwin's saliva. Knowing that he'd be tasting both men at once made him shiver.

Circling his fingers around the base, Armin sank his mouth down. He took Levi's oral advice from last week and didn't try to fit the whole thing in. Instead, he found a manageable amount, and focussed on sliding his mouth up and down in a steady motion like Erwin had shown him.

Levi hissed from above. Armin almost pulled off, assuming he'd done something wrong.

"Fuck Arlert," he whined. "That's so good."

Erwin's hand brushed Armin's hair, smoothing his fringe away from his face.

"You're doing great, Armin," he said huskily.

Giving oral wasn't exactly Armin's favourite thing in the world to do. But the sinful noises coming from Levi, and both men's ardent praise, was reward enough.

From what he'd gathered, Levi had never been with anyone except for Erwin. So Armin was probably the only other man to perform this intimate act for him. That thought, along with the Captain's encouraging reaction, made his own cock grow hard in response.

He kept his eyes closed to stop himself from feeling overwhelmed. But he could tell Erwin had resumed fingering Levi, making the man's body judder and tremble in response to the double stimulation.

Suddenly, a loud groan spilled from Levi's lips and his hips jerked upwards. His cock shoved against the back of Armin's throat. He pulled off him spluttering.

"Shit, sorry Armin," Levi gasped. He rubbed a hand soothingly over his shoulder. Even through his coughing fit, Armin's heart did a little flip at the Captain's use of his first name.

Erwin's free hand snaked around Armin's back. "I hit his prostate," he said with an apologetic wince. "Are you alright?"

Once Armin got his breath back, he assured them he was fine. Levi insisted he move back up on the bed beside him. Armin awkwardly wiped at his mouth and chin with the back of his hand.

"Here," Levi said gruffly, grabbling a towel from the bedside cabinet and handing it to him. "Sex is so fucking messy, right?"

"Yeah," Armin chuckled. He still couldn't believe he'd just given oral to Humanity's Strongest Soldier. And earlier had received oral from the Commander of the Survey Corps himself. But Armin would never be able to share these incredible conquests with another soul...

Levi toyed with the frilly edge of the pillowcase. "That was really good Arlert. But you're never obligated to do it unless you want to, alright?"

Armin nodded. He felt as though he could burst from happiness. He definitely wanted to try it again sometime, but perhaps not until another night.

Erwin watched them, face shining with affection. "Are you ready for more, darling?" he asked.

"Yes." Levi set his shoulders with resolution. All traces of his previous nerves had vanished.

Erwin clambered away from him and off the bed. He washed his hands in the bathroom before returning. Then he started undressing – pulling off his shirt to reveal his broad, muscular chest, and then his trousers. Face burning, Armin averted his gaze.

From the edge of his vision, he saw Erwin return to the bed, and felt the pressure of the mattress dip beneath his weight. Armin kept his gaze focussed on Levi with a steadfast determination.

The Captain smirked. "Don't be nervous. I'm the one that's about to get fucked by that massive cock."

Speechless with mortification, Armin didn't reply.

"Could you maybe keep touching Levi?" Erwin suggested, voice laced with amusement.

Without looking down, Armin dutifully gripped Levi's cock again, stroking it the way he'd been shown earlier. He jumped when a large hand covered his own.

"You're doing great, Armin," Erwin said earnestly.

His stroking movements stalled at the shock of this intimacy. Was this another possessive gesture? Was the man trying to remind him that Levi's cock, as well as every other part of him, belonged to Erwin?

"Sorry, I didn't mean to throw you off." The Commander calmly guided Armin's hand back into a steady stroking motion on the erection under his grip. Then he let go, allowing the younger man to resume control.

Armin couldn't resist it any longer. He glanced down at Erwin positioned between Levi's legs. He had opened the bottle of lubricant again and was pouring some onto his hand. Then he slathered the oil over his fully erect cock. Armin's heart froze at the sheer size of it.

I still can't believe how that fits inside Levi… even after all the preparation.

Erwin lined himself up at his partner's entrance; gripping his hips to level him up at an angle. Armin's already erratic heartbeat went into overdrive. His stomach clenched in anticipation.

Realising both men were looking at him, Armin decided to actually do something instead of ogling like an idiot. He leaned over Levi and claimed his mouth again.

This time, Armin managed to take control of the kiss – throwing all his focus into it, even as Levi's body juddered underneath him. Soon the Captain was making little incoherent noises in his throat. Suddenly he broke the kiss, panting, his eyes dark with pleasure.

"Erwin!" he moaned. "Fuck, right there."

Armin's head swivelled irresistibly back towards the larger man. And discovered he couldn't tear his gaze away.

Gone was the calm, courteous, gentlemanly Commander; replaced with a man who drove into the Captain with deep, demanding thrusts. Sweat glistened on his face, his usually combed-back hair hung in clumps over his forehead, and the veins on the backs of his hands and arms bulged with how tightly he clutched Levi's thighs.

Trapped under this relentless assault, the Captain stammered incoherent pleas, face screwed up and lips quivering, head thrown back against the pillow.

Erwin continued sliding in and out of his partner, while his eyes bored right into Armin's.

Realising his mouth was hanging open, Armin hastily shut it. His head was filled with intoxicating images of the Commander fucking him. He could tell from Erwin's predatory gaze that he was thinking the exact same thing.

"Don't neglect your Captain," Erwin admonished him with a smirk.

Armin quickly turned back to Levi beside him. The man was squirming with pleasure, seeming to have forgotten about Armin entirely. Noticing his fringe was plastered to his temples, Armin brushed it aside.

Levi's stormy grey eyes snapped open. "Can I touch you Arlert?" he growled.

Armin's breath caught in his throat. "Yes," he managed to whisper.

Levi lifted his head slightly off the pillow to survey Armin. He glared at his trouser-clad legs, like the sight was a personal insult to him. "Take those off."

Armin licked his lips. Sure, he'd been naked in front of them before. But somehow it would be worse this time, with the other men undressed too. Their physical differences would be very obvious.

All his failings stacked up in his mind. I'm not like either of these men – not as confident, experienced, or as physically impressive. Why do they even want me here at all?

But the earnest glint in Levi's eyes challenged Armin's inner turmoil.

They don't want me to be like them… they like that I'm different, he realised. And with that, his doubts crumbled into smoke.

He wriggled out of his trousers and underwear, tossing them at the far side of the bed. Feeling the most vulnerable he had all evening, he crawled back over to Levi.

"Damn it brat, you're rock hard again." Levi smirked as his cool hand gripped Armin's cock. "You must really love watching your superiors fuck."

Trying not to think about the view he was presenting to Erwin, Armin braced himself on his hands and knees so he was half lying over Levi. Soon his lingering nerves melted away, and everything hazed into a blissful blur.

He and Levi shared hot, wet kisses; soft moans mingling in their mouths as they touched and stroked each other. They broke apart for good when it became impossible to regulate their rapid breathing. Their moans filled the air instead, blending with Erwin's guttural groans.

Both men's hands roamed over Armin, mapping out his body like uncharted territory. Through the mounting pressure building in his every nerve and muscle, he lost track of who was touching him where. Hands raked through his hair, massaged across his shoulders and back, gripped his waist, hips and thighs, pumped his cock, squeezed his ass…

His orgasm crashed over him like an unrelenting wave. He had just enough presence of mind to pull away from their greedy grasps to grab a towel. He came into it, and collapsed panting on his back.

Armin's body floated in a heavenly state of transcendence. He watched Erwin pick up the pace, pounding into the Captain relentlessly, as the smaller man whined and writhed. Their shared cries and the slap of skin-on-skin filled the room. Armin leaned over to give Levi a few more teasing strokes, circling his thumb over the leaking tip.

Something that sounded like "Ermin!" burst from the man's lips, and a hot rush of liquid covered Armin's fingers. The slightly uncomfortable sensation was overcome by his satisfaction. He'd just helped to get off the infamous Levi Ackerman. He couldn't help feeling a little smug about the achievement.

Erwin thrust into his partner a few more times, before stuttering to a halt deep inside him with a final groan.

Armin grabbed the towel again. He wiped his sticky hand, and, after a brief hesitation, began wiping the wet patches on Levi's belly.

Levi flinched as if burned. "I'll do that," he said, snatching the towel. After a few seconds he added in a softer tone, "Thanks though."

Sometime later, after they'd all cleaned up, the three of them lay together under the covers of the bed.

Armin lay enveloped between the two men, sleepily answering their endless questions - Did he enjoy the night? Was there anything he'd like to do differently next time? Did he want some tea? Or to shower here before he left? Was there anything at all he wanted to discuss or ask them about?

The murmur of their voices grew softer and softer, as Armin sank deeper into a pool of hazy contentment.

Moments later, a hand shook him gently. He startled and opened his eyes.

"Armin?" Erwin's handsome features were twisted in an apologetic grimace. "Sorry to wake you, but…"

He was too kind to finish his sentence – but it's time for you to go.

Armin's heart clenched. After everything they'd done together tonight, he was being unceremoniously kicked out?

Stop feeling sorry for yourself! They've treated you with nothing but respect so far. You have nothing to complain about.

He couldn't deny that they were right - sleeping in their bed was overstepping the boundaries of their arrangement.

"I better go," he said.

He wouldn't embarrass himself by asking to stay on a little longer, no matter how warm, cosy and secure he felt. Those types of feelings would surely lead into dangerous territory. This threesome was about sex after all - not seeking comfort or companionship.

He clambered over Erwin to reach the edge of the bed. As he fumbled around in the dim light to grab his discarded clothes, Levi's dry voice cracked the silence.

"Same time next week?"

Buttoning up his shirt, Armin turned back towards them. Levi had moved into the gap vacated by Armin, with his arms wrapped around Erwin.

It was an unmistakable message - Levi and Erwin belonged to each other. While they both enjoyed having a bit of fun with him, he had no long-term place in their relationship.

He hardened his bruised heart. That's fine with me. It's best we all know where we stand.

"Yes. Next week suits me too," he confirmed.

"I'll walk you to the door." Erwin began disentangling himself from Levi to get out of bed.

"Oh no, it's fine," Armin assured him. As much as he'd enjoy another few stolen moments with Erwin, he wouldn't be that selfish. His time with these men was over for tonight.

After saying goodbye, he left their bedroom, and made his way back through the Officer's Building to his own empty quarters.


Notes: I hope you didn't mind the Second Night being split into 2 chapters – this story takes a lot of time and energy, and it was easier for me to cut this long scene in half.

So we'll be getting some progress on Armin's 'normal' life in the next chapter. (Yes, that means more Floch!) Prepare for angst… but also smut and comfort.

Let me know what you thought of this chapter – did you like the three-way sex? How are the Eruri, Rivarmin, and EruAru shippers all feeling about the mix of dynamics so far? (I try to balance things overall, but some chapters might lean more heavily towards certain ships).

I have lots of exciting things planned for this story - both in terms of kinky smut and soft romance. And of course, DRAMA. So stay tuned, and please share your thoughts! Also this story is over 50k now, it's officially the longest thing I've ever written.
