Work Text:
“Can we come in, sir?” Fives asks, a fresh bruise high up on his neck showing over the collar of his blacks. Echo doesn’t say anything but his focus is sharp even as he tries to dull it.
They don’t step over the threshold into his quarters before being invited, but they crowd the doorway, making Rex want to step both closer and away. He should send them away. They haven’t been subtle—Rex doesn’t think they've been trying to be subtle—and Rex already knows how this will end. They’re a hard pair to want to say no to.
Echo backs Fives up against Rex’s desk, Fives’ hands splayed behind him, pushing the scattered items on Rex’s desk aside to make space. Each kiss they pass between them is deliberate, loud and wet, chasing each other when one pulls back to breathe. It’s all for the benefit of their audience—two shiny troopers wanting to put on a show for their captain.
Fives dares a glance over at him. He smiles, cheeky for all that it’s cautious, well aware that Rex hasn’t agreed to anything yet. He agreed to let them in, he agreed to let them try to convince him, but no more. Echo pulls Fives’ face back, hand going between Fives’ legs and—
The way Fives’ breath hitches is intoxicating. Rex could get the same sounds out of him. He could pin him like Echo has. He could have Echo pin him like Fives. They’ll give him anything he asks for and take as little as he offers in return.
It’s why it’s all such a bad idea.
Echo pulls his own shirt off first, dropping it to the floor. He has none of the doubts Fives has. He’s decided how this is going to go, and will see to it that it does. Fives lifts his arms and allows Echo to pull his shirt off too. Fives hooks a finger into the waistband of Fives’ lowers and pulls him back close.
Rex keeps his blacks where they are.
Echo and Fives look at him the same way he used to look at Cody, like he isn’t quite real. His reputation and skill are blinding, eclipsing any hint of the man behind them. Fives and Echo don’t know him, they don’t even know that they don't know him, they came here to seduce Captain Rex of the 501st, not Rex.
He should tell them to leave. Politely send them back to their bunks and forget about this whole thing.
Echo moans into Fives’ mouth as Fives’ hands wander. Fives grabs at Echo’s ass, fingers sinking in deep. Echo puts his hands in Fives’ hair and tugs. Fives groans Rex’s name. They can’t see the cracks under Rex’s armour. He could strip bare in front of them and have sex with them any way he wanted and they wouldn’t see anything but the version of him they wanted to see.
If he’s going to send them away it needs to happen now.
Echo breaks the kiss with a wet smack that fills the whole room. He keeps one hand on Fives, reminding him to stay where he’s been put, but turns to look at Rex, the unspoken question as obvious as the bulges in Echo and Fives’ lower blacks.
There’s a new tattoo over Echo’s chest, blue like his paint, a hand that could belong to any of them but is undoubtedly Rex’s. Rex hadn’t touched skin, only armour. It’s unnerving, a man he barely knows branding himself with Rex’s hand. It’s too forward and Echo looks at him, daring him to challenge it.
Rex swallows. It’s too much. He wants to touch it.
He doesn’t move, keeping his chin up and his arms folded, the immovable officer.
Fives pushes Echo towards him. Annoyance settles over Echo’s face—this can’t have been part of the plan—and even as he adjusts to this new situation, the expression lingers. His hands on Rex’s waist are firmer than Rex might have expected, and wander more boldly.
If Echo knew him, this might all look very different.
It’s simpler in many ways, to just be the captain and not have to worry about being Rex.
Echo kisses him, lips already wet from Fives, and Rex puts his palm over the tattoo, Echo’s pec twitching under his hand. He’s warm, and the edge of the tattoo is still slightly raised.
Rex and Cody saved their lives, but it was Rex who took them back to his battalion, Rex they’ve followed into battle over and over, Rex’s room they’re in, Rex Echo is kissing.
Cody had called them their troopers at first, and joked about the hero worship in their eyes. He calls them Rex’s now, in the middle of sentences about how impressive their performance is.
Rex steps forward, just to make Echo step back. He keeps one hand on Echo’s chest, but abandons the tattoo in favour of twisting his nipple until Echo gasps, hips twitching. Fives smiles in the corner of Rex’s vision.
Echo doesn’t kiss him like he kissed Fives, all attempts at putting on a show gone in favour of making certain Rex knows exactly how sweet Echo’s mouth can be when he’s not talking.
It’s compelling. Echo’s mouth is soft, and his tongue curls against Rex’s. He could put Echo on his knees and fuck his mouth and afterward Echo would say ‘thank you, sir’ more sincerely than he ever has before.
Rex’s cock starts to swell against Echo’s hip.
“I was impatient, sir,” Fives says, the first words that have been spoken in a while. Echo breaks the kiss but doesn’t move until Rex touches his shoulder, guiding him to the side.
“You were,” Rex says; it was supposed to be a question, but his voice doesn’t lift the way it should. Fives flushes, ever so slightly, looking down and then back up.
“I’m sorry, sir. I saw an opening. I had to— I thought I had to take it. It won’t happen again.”
“He’ll follow orders next time,” Echo says, and he feigns unquestioning obedience so much better than Fives can. He quotes the regs and snaps to attention without being told, but all the time his mind is slowly turning over any situation, feeling out all his options. The pair of them are still green, but they have the capacity to go far.
Rex drops his hands from Echo’s hips and Echo takes a step backwards, closer to Fives.
“Fives and Sergeant Appo have already discussed this.” Rex had skimmed the report and moved on to other things, trusting Appo to manage his own men. “Why bring it to me?”
The pair exchange a look. They’ve talked this through, planned how to present their case.
“We have a system,” Echo says. “For when one of us is out of line. As it was your orders that he disobeyed, we wanted you to be involved.”
Fives bites his lip and looks at Rex with unabashed want.
Rex stares him down. He’s going to agree to whatever they have in mind, everyone in the room already knows that, but he’s not one to turn his nose up at recon.
“What system,” he asks. He folds his arms over his chest, a clear line that they aren’t to push their luck by moving back into his personal space. They wanted the captain, they’ll have to deal with him.
Echo over-prepares, it’s a flaw he’s improving, but it comes out now as the beginnings of a prepared speech. “We’ve been using it since Kamino, its effectiveness likely contributing to—”
“What system, Echo?” Rex repeats. Echo’s mouth snaps shut.
“I spank him, sir.”
It’s so simple, so far from the heights he’s sure their imaginations can reach, and Rex is pulled in all the same.
“Does he enjoy that?” Rex asks. He knows the answer.
“Yes, sir.” They say it at the same time, with no shame, only lust cut with growing optimism that they’ve convinced him.
“Doesn’t seem like much of a punishment, then.”
“It’s not a punishment, sir,” Fives says hurriedly, earning the flash of a frown from Echo. “Appo has already punished me.”
“We ask for it, sir, not prescribe it.” Echo’s clarification dips hot down Rex’s spine to settle between his legs. Rex would have thought it a hard act to follow, but Fives can never be underestimated.
“Would you spank me, sir?” he asks.
They’re so dangerous.
“Show me,” Rex orders.
The pair don’t waste time, leaping into action.
Fives pulls down his own blacks. There’s no graceful way to do it—Rex has tried—they cling too tight, and Fives is left balancing on one leg, using first one foot and then the other to shove them the rest of the way off. He has no hand prints of his own, but while he may look like any one of their brothers, the subtlety of how he inhabits his body is uniquely Fives.
He likes the way he looks and he likes the way Rex looks at him.
If it were anyone else, or if they weren’t all bound up in the rules their actions had established, he might comment, might tell Fives how attractive that confidence is, but as an officer Rex is deliberate about his praise. When he tells someone they’ve done a good job, he means it and he wants them to know that. He won’t tell Fives he looks hot just to settle his nerves.
“Do you have cuffs, sir?” Echo asks.
“In my locker.”
The pair don’t hesitate, opening Rex’s locker like it’s their own. They don’t get a chance to dig, his cuffs are exactly where they should be, along with the rest of his kit.
Echo puts Fives’ hands behind his back and Rex’s cuffs click into place. Fives’ muscles tense under his skin as he tests the strength of them, but that’s the only thing he tests. Echo bends him over Rex’s desk with the lightest touch to his shoulder. He makes a lovely sight. His station on Rishi had made him lazy, but with the 501st he’s flourishing, pushing himself to keep up with the honour he’s been given. His and Echo’s time in the gym is paying off, and they’ve both filled out.
It’s never been more apparent than with Fives bent over his desk, his tight ass displayed to the room. Fives looks like that because of the chance Rex gave him. He looks like that because he’s been striving to meet Rex’s expectations.
He shouldn’t have let them into his quarters.
Echo plans for everything. He knew Rex would have cuffs, but he’d brought everything else he’d need: a packet of lube; an almost finished roll of medical tape, the edges worn and the end curling; and two small vibrators, with an equally small remote. Echo places the tape, controller, and one of the vibes down on Rex’s desk. He glances once at Rex to ensure he’s being watched and rips open the lube.
Clear lube oozes from the packet down onto the vibrator, glistening in the light. Fives is still, showing a patience that Rex wouldn't have suspected he’d see in such circumstances. He shouldn’t be so surprised, Fives might act when he sees an opening—orders or otherwise—but he’s more than capable of sitting and waiting for that opening to appear.
Echo pushes the vibrator up against Fives’ ass, pushing it in deeper with his fingers until only the short cord hangs out of Fives. Echo wipes the lube off on his blacks and moves onto the next vibrator. He attaches it with the medical tape to Fives' cock, up near the base, and he does it as efficiently as any medic has ever used that same tape.
Echo’s focus is something Rex admires even if he thinks Echo would benefit from being more reactive in the field. He’s never imagined how that focus would look in a situation like this. It’s hot. Rex wants to kiss him again.
He’s giving them too much rope and they’ll hang him with it he doesn’t stop them.
“Give me the controller,” Rex says. It comes out as an order without him even thinking that it should be, and Echo snaps to obey. It’s a small thing, simple with only one button. Rex presses it with his thumb.
Nothing happens.
He presses and holds and Fives jerks against the desk, his cock bouncing between his legs. A soft buzzing fills the room, and Fives’ breathing quickens.
“In your own time, trooper,” Rex says.
Echo doesn’t hesitate to obey that order either. His hand comes down on Fives’ ass with a crack, no gentle warming up, nothing to ease Fives into it. Fives gasps, arms tensing against the cuffs.
Echo spanks him again, hand landing on the same side, over the same spot. Fives’ hips twitch and precome beading on the edge of his cock falls to Rex’s floor with a splat.
Rex clicks the button again, the buzz changing from steady to short, sharp bursts. With Fives’ legs spread, the clench of his asshole is obvious to anyone who’s looking. Rex is looking.
Echo is methodical, five on the right side, five on the left and then back. Fives’ stillness cracks after the fourth strike. He wriggles and moans, pushing his ass up to meet Echo’s hand and then flinching away. His cock bobs and leaks, and every time Rex changes the pattern of the vibrators he reacts with his whole body, squeezing around the vibrator.
They’re a gorgeous pair.
Rex isn’t naive, he knows they’re still putting on a show, still showing him what they think he wants to see. But they aren’t as far off target as they could be and how can Rex not be flattered at the effort they’ve put into this?
Fives’ ass goes from brown to red.
It’s rhythmic in a way that Rex wouldn’t expect something like this to be, Echo holding the tempo, but even Fives’ responses are on beat, slowly building in intensity. Rex is the only source of change, tapping his thumb on the button before pressing it. Fives can’t predict it like he can with Echo and his responses are so much more honest for it.
“Fuck,” he groans. “Sir, please, I—”
Echo’s hand comes down right on schedule. Fives lets out a beautiful wet gasp and Echo glances at Rex and then back to Fives.
They’re all waiting for something, waiting for Rex to take Echo’s place.
Rex presses the button again and Fives’ whole body jerks. Echo hasn’t moved, has made space for Rex to step into. Rex fiddles with the button, until the vibrators buzz softly, building and building and then cutting off, just to start all over again.
Rex had even had to ask for the controller.
Echo isn’t going to invite him to get closer.
Rex is the officer here, he’s running this show. He told Echo to start, he has to be the one to tell him to stop. It’s obvious, but Rex had forgotten the game.
He cycles quickly through the settings on the vibrators, leaving it on the most powerful, the one that makes Fives pant through his teeth and his toes curl on the floor.
“Echo, that’s enough. I’ll take it from here.”
Echo steps back quickly, but it’s not his characteristic promptness, but unabashed eagerness. When Rex offers him the controller he takes it, but doesn’t retreat to the same distance as Rex, staying close. For the best view or to supervise?
Fives’ ass is hot to the touch. He shudders as Rex runs his hand over the curve of it.
Rex takes the cord of the vibrator in Fives and pulls, tugging until it’s right at Fives’ entrance, pulling Fives’ hole wider around it. Rex lets go and it sinks back into him. A line of lube slides down the cord to Rex’s finger.
The crack of a hand hitting Fives’ ass is a very different sort of compelling when it’s his hand.
“Thank you, sir,” Fives gasps.
Rex steadies himself with a deep breath, forcing himself to be slow, to not let how powerful he feels go to his head.
He spanks Fives again, hand coming down flat on his other cheek.
This time Fives takes a moment, shoulders trembling, before repeating himself. “Thank you, sir.”
Rex has played games like this before, played them with different people in different positions. He’s not sure he’s ever been with someone who believes the role he’s occupying as much as Fives and Echo do, and it makes the lines blur.
He doesn’t follow the pattern Echo had set, bringing his hand down on a random side with no rhythm to speak of. Fives though, is consistent.
“Thank you, sir!” he hisses, pain colouring his voice as much as the obvious arousal. Is it the pain he enjoys or the submission? Is it Rex himself?
Rex’s hand already stings, Fives’ ass must be burning. Still, his cock is durasteel hard and still Fives gratefully takes each spank.
Rex's hand smacks down onto Fives’ ass, the fat bouncing.
“Thank you, sir!” Fives wheezes, voice straining, back tense, cock leaking. Rex wants to push him, wants to see what too much looks like on Fives, to see how that abuse of power and trust looks on him.
He looks questioningly at Echo—trusting Echo more with Fives’ limits at this moment than he trusts Fives. Echo only nods, eyes wide, staring at his brother.
Rex brings his hand down again with a crack that fills the room and Fives breaks the pattern.
“Shit.”
Liquid splashes against tile. It’s not come, but what else could it be?
Rex is hit by the smell and realisation all in the same moment.
Fives has pissed himself. It’s just a little, a spurt of urine escaping him, splashing to the ground in front of Rex’s desk.
Rex is dizzy. His cock throbs and the urge to hit Fives again roars like a hungry beast. He can’t. He shouldn’t.
“Please, sir,” Fives gasps. “Again.”
It’s all the encouragement Rex needs, and this one bursts the dam.
Fives is tense under the flat of his hand, straining to avoid making more of a mess but with a gasp and another curse, that effort is rendered moot.
It’s not just a little spurt this time either. The stream is loud on the floor, yellow on dulled white. Fives moans with an intensity that could have been mistaken for an orgasm if not for Rex’s eyes being locked on the liquid escaping him. Rex steps back from the puddle forming at Fives’ feet, hand burning, cock unsure where this leaves them.
Did they plan this? It’s a hell of a risky plan. Fives is blushing, face as red as his ass, avoiding Rex’s eye. Echo’s face is almost blank, but his eyes are fixed on Fives, and opened wide. Neither reaction provides a clear answer. Everything here has been a carefully controlled act, but the troopers aren’t yet as good as they think they are—they’re more than capable of miscalculating.
Have they miscalculated?
Urine drips from Fives’ cock to the puddle below. No one speaks, but it’s far from the only sound: the vibrators still buzz and Fives pants.
Rex does the only thing he can do, rendered speechless as he is. He folds his arms over his chest and lets his silence be deliberate, lets them stew in the mess they’ve made.
Fives squirms, literally and figuratively, shifting his weight, squeezing around the vibrators, looking anywhere but at Rex. Echo remains perfectly still, but he’s the one that breaks first.
“Sorry, sir,” Echo says.
“Sorry, captain,” Fives adds.
“Was this intentional?” he asks.
“It happens sometimes,” Echo says, which isn’t an answer. Rex doesn’t think he wants to push for one.
“Would you like to come, Fives?” Rex asks, eyes still on the urine. He caused that. It makes him feel hot in a way he hadn’t expected.
“Yes, sir.”
“How?”
“I’d like you to fuck me, sir.”
Rex steps back up to Fives, stepping into the piss, letting it soak his socks.
He shouldn’t have let them in. He doesn’t know what to do with this.
He can picture himself in Fives’ place, spanked and teased to the point of humiliating desperation. He can picture pulling Fives up and ordering him to lick up the mess he’s made. He can picture too much, wants too much. He’s not the person they think he is and they aren’t the people they’re pretending to be.
He brings his hand down for a final time, lighter than at any other point that night. Fives hisses, but doesn’t pull away.
“Are you going to thank me for that one, trooper?”
“Yes, sir. Thank you, sir.”
The vibe slides out of Fives’ ass without resistance. It hangs by its cord from Rex’s fingers, buzzing angrily. Fives’ hole is shiny from lube and it would take a stronger man than Rex to turn down something so willingly offered. He passes the vibe to Echo, pauses only long enough to shove down the front of his blacks, and putting his hands on Fives’ hips, pushes into him.
Fives thanks him for that too.
The abused skin of Fives’ ass is almost as hot against Rex’s groin as his insides are around Rex’s cock. Both are impossible to ignore. He’d been right that Fives and Echo would take whatever he was willing to offer them. He fucks Fives selfishly, caring more about his own release than Fives, but Fives takes every thrust like it’s the best thing that’s ever happened to him.
“Please, sir. I’m close, captain, please, I—” the rest is lost in a groan, but he picks right up again. “Captain, sir, harder, thank you.”
It’s not an act, not really. This is how Fives sees him, how they both see him. Rex fucks deep into Fives and Fives thanks his captain for the privilege.
Rex’s feet are soaked, and the sharp smell of piss is taking up increasing space in the room. It will be a problem later, but for now Rex can’t say he minds.
Echo shifts closer, hovering at Rex’s shoulder, hand in his lowers.
“Captain, please, thank you, please, please.” Fives is so tense, so tight around Rex, words spilling out in an endless stream.
“Could you keep the dribbling from just one end?” Echo asks, and Fives abruptly stops talking.
Echo can be mean. This isn’t the first time Rex has noticed, but it’s the first time he’s been involved enough to respond in kind.
“Do you wet yourself when Fives spanks you?” he asks.
Echo stiffens, back straightening, shoulders pushed back. There’s a set to his jaw, the persona he’s so carefully curated for Rex slipping.
“No, sir,” he says, cold as ice.
Rex is too close to Fives to not notice the way he shifts, differently from the way he’s been wiggling.
“Fives?” Rex prompts.
“He cries, sir,” Fives says.
Echo flushes at least as prettily as Fives does. “No, I don’t.”
Rex doesn’t believe him. He bets Echo looks even prettier when he cries. He snorts derisively, and Echo’s nostrils flare at being doubted. He doesn’t have time to argue because Fives has a very different reaction. The vibrator still taped to his cock and everything else they’ve put him through finally combines into too much and he orgasms, come landing wetly into the piss between his feet.
Echo’s annoyance vanishes, turning to a small smile instead. His thumb hovers on the vibrator controller, stringing Fives out until he’s clenching and twitching around Rex’s cock before finally turning it off.
Rex could keep fucking him, ride him through the over stimulation for his own benefit. Rex isn’t that sort of man, and he’s certainly not that sort of captain.
Rex pulls out, taking himself in hand and finishing over Fives’ ass, adding white to red. Rex is still, unable to do anything but admire the view.
Fives shifts, and the cuffs click against each other. Rex almost forgets who they’re convinced he is and jerks to find the key, unlocking Fives’ hands. It breaks the last remains of the fantasy where this wasn’t an awful mistake.
They’ve made a mess and the floor of Rex’s quarters are the least of it.
“Clean this up,” he orders, because orders are a comfortable thing to fall back on. Echo moves, and Fives stays where he is; Rex can’t say he blames him. Echo finds wipes and cleaning spray without direction.
Fives’ skin is still hot to the touch, red starting to bruise. This was careless and part of Rex wants to spank him again. He withdraws his hand, curling it into a fist and crushing the temptation.
“Do you have something for this?” he asks.
“Yes, sir. I’ll take care of it,” Echo says.
Rex could insist he be the one to do it, but he’s relieved at the chance to step away from Fives and put his back to both of them. Behind him his desk creaks as Fives finally pushes himself upright. Echo drops to the floor and starts mopping up the piss, pausing only to spray cleaner down.
Fives murmurs to Echo, and Rex does his best not to hear it. He peels off his socks and shoves them into the laundry chute. He’ll need to shower. He’ll need to wipe the floor down again after they’ve left, to clean up his own damp footprints.
He can’t refuse to look at them for long before it becomes obvious. He turns in time to catch the end of Fives redressing, pulling his blacks back up with far more care than he’d removed them, wincing as they snap over his ass. If they get bacta on it quickly the worst of it will be caught before it can take hold, but either way Fives will be sore tomorrow.
Rex will know to look for it now, even if he’s never invited to join in again. When Fives is lagging in regular training, standing when it would make more sense to sit, he’ll know.
Echo too, though Echo might sit just to make a point of it.
If Rex wants to, he could push Fives tomorrow, make him run extra laps, do extra sparring; Fives would likely enjoy it for all that he’d hate it.
Echo has taken care of himself somewhere in the proceedings. Should he have been more involved in that? Should he offer to help Echo out now? It would probably be the polite thing to do, but now his cock isn’t hard, the reality of the situation stretches out in front of him. This was a bad idea.
The troopers stand awkwardly in the middle of his room, shoulder to shoulder. Neither of them manage anything close to the soldier’s posture he’s come to expect from them, Fives sore from his spanking, and Echo having not taken much care with how he’s put himself away, leaving an unprofessional bulge in his lower blacks.
He’ll get Echo off personally next time, maybe make a liar of him and make him cry.
“Thank you, captain,” Fives says. He really means it.
“Yes, sir. Thank you.” Echo too.
He thinks he might let them put him over the desk and find out how he handles it all. He might if it wouldn’t change how they see him, dent the illusion of him they’ve created. He’s not ready for them to stop seeing him as the captain of the 501st yet.
“Go to bed, troopers.”
Fives hesitates as he passes, for a moment considering kissing Rex, but the intention flickers off his face just a moment after it appears.
“Goodnight, sir.”
“Goodnight, captain.”
They’re gone as suddenly as they arrived, but their presence lingers. If it wouldn’t mean explaining himself he’d reach out to Cody for advice, but Cody’s judgement is the last thing he needs right now.
Rex leans against his wall, head dropping back against it. The smell of piss is gone, replaced with cleaning fluid. His hand stings. He still has work to do.
How long until they show up at his door again?
Rex will let them in, won’t be able to help himself as long as they look at him like that.
They’ve got him exactly where they want him.
