Rex/Fives/Echo dom Rex subs Echo and Fives nsfw? If you’re comfortable with it Fives experiencing a sub drop?
(I’ll admit I’m not an expert on the subject but I tried. I hope you like it! Also oof this might’ve been the hardest prompt to fit in 1000 words or less...)
“I told you to be quiet, trooper.”
Rex voice is hard, vicious and sharp. It makes Fives shiver as he weakly nods, earning himself another slap.
Rex remembers the first time Fives and Echo came to him for this.
He didn’t have much experience in this - he was usually on the other side of things, shall we say - but he’s grown more confident time after time. After all practice makes perfect, doesn’t it?
He looks down through his visor, enjoying the sight of Fives fucking Echo while Rex’s cock is buried deep inside him. They both have their hands tied behind their backs and, unlike Rex, they’re completely naked.
At first he wasn’t sure about wearing his full armor, but he’s grown fond of the practice: it helps to separate himself from the scene, and also taking if off is a good indicator of when things go back to normal. Besides, he’d lie if he said that hearing Echo and Fives call him Captain during these moments doesn’t do things to him.
Mmmh, Fives is truly giving his all, despite how hard it is for him to move. He’s earned himself some help: Rex grabs him by the hips, grip solid and ironlike, and after a moment of stillness, begins pounding into him, putting enough strength behind his thrusts that he manages to push Fives into Echo. This time, however, Fives has no power for himself, no way to dictate the rhythm anymore.
“Captain!” Echo moans, causing Rex to slap Fives’ ass.
“I said quiet!” he exclaims, trying not to soften his voice at the way Echo flinches. There will be time for softness later. “Or do you want me to keep punishing Fives for your mistakes?”
Echo shakes his head without making a sound. Smart boy.
“Now be good if you want to come.”
Once they’re all done, every single one of them is incredibly spent. Still, Rex is aware of his responsibilities, and he would never shrink them: he helps both Fives and Echo get cleaned, he looks them up for any injury, he treats their bruises, kisses them, praises them and, after taking his armor off, lets them cuddle close to him and holds them as they recover.
“Are you sure you’re both ok?” he asks, because he’d never want to be - even indirectly - cause of discomfort. “Anything you need.”
“We’re fine…” Fives chuckles, burying his head against Rex’s chest.
“Just keep holding us?” Echo helpfully suggests.
Well, this is something Rex can absolutely do.
Something’s weird with Fives: during missions, he’s always focused and on the job, but today it feels different. Since Rex has stepped into the barracks, armor just polished and bucket already on his head to tell them men to get ready, he’s gotten weird vibes from him.
He barely reacted, first of all, and he kept staring at Rex with such an empty gaze that after he was done Rex even asked him if he was alright; that seemed to shake him a bit and he says yes, that he was just a bit tired, but nothing he wouldn’t have been able to handle.
Turns out, that was a lie.
“Do you know why I summoned you to my office?”
Fives just stares at Rex, impassive. “Yes, sir.”
“You almost blew up this entire mission, don’t you realize that?!” Rex exclaims, unnerved by Fives’ demeanor; he slams his palms against his desk, not missing the way Fives flinches at the sound. Ok, maybe it’s too much, but Fives needs to understand! “Look, we’re not always up to the challenge, I know. There are days in which we simply don’t feel good, it happens to all of us. Part of being a good soldier is also realizing when you’re not at your best and stepping out! You realize that we could’ve died if the General wasn’t there? Fives, I expected better from you…”
“I know…” Fives immediately mutters, swallowing, but then hardening his gaze. “I know this, Captain, but I…”
His body begins shaking, which causes Rex to immediately drop the angry act as he rushes to the trooper’s side.
“Fives, are you ok?” he asks, worried.
“I don’t know,” comes the reply, before Fives breaks down crying. “I’m sorry, I’m sorry…”
Rex doesn’t think about it not even for a moment as he gathers Fives in a hug.
“Are you feeling sick? Should I call Kix?”
Fives shakes his head. “No, I’m not sick.”
“What is it then, Fives? Please, talk to me.” Rex can’t intervene if he doesn’t know what’s wrong with him.
He helps Fives sit on his desk - the man could barely stand - and he stays there, in front of him, keeping his face gently in his hands, knowing that even the smallest touch will ground him.
“It’s just… After, you know, we did the thing…” he begins explaining. Alright, they’re getting somewhere.
“Did something happen there?” Rex doesn’t remember anything particular happening, but maybe from Fives’ point of view it did.
“No, it was great,” the other replies, shaking his head. “It was after: I don’t know, I was just feeling down, then you came in, strolling in your armor, and I thought back to that and I…”
Oh, now Rex thinks he understands. He should’ve thought about it sooner.
“You should’ve told me that you were feeling like this,” he says, mindful to keep his voice gentle.
“But I never felt like this after we fuck, Rex! I was so afraid that I hadn’t been good enough…”
“No, Fives. You’ve been good,” Rex immediately cuts him off, figuring that it’s best not to let that train of thought continue. “You were amazing actually, and I’m so very proud of you.”
He slowly leans in to kiss his lips.
“What you’re feeling is completely normal. It happens sometimes, even after a session, so there’s nothing wrong with you, alright?”
Fives weakly nods. Rex kisses him again.
“Do you want me to call Echo?”
Fives nods again, this time with more conviction. It takes very little for Rex to comm Echo, asking him to join them in his office, only to then turn towards Fives.
“Alright, what else do you need?”
Fives hesitates just for a moment.
“Could you take your armor off? It makes me think about… You know…”
Rex nods, already unclasping his bracers. If it makes Fives feel more comfortable, so be it.
By the time Echo arrives, both Rex and Fives have gotten rid of their armors.
It doesn’t take them long to explain what’s happening, which prompts Echo to immediately tell Fives: “You could’ve told me you were feeling like this.”
“I know, it was dumb… Sorry.”
“Oh well, at least we know now,” Echo immediately backtracks, unable to resist with Fives looking so down.
After Echo gets rid of his armor as well, they all cuddle on Rex’s couch. It’s not too comfortable - it’s an old thing that couch - but as long as they’re close, it’s good.
At least Fives has calmed down, Rex thinks, mindlessly caressing his hair; he always melts when he’s pressed between him and Echo, though this time there’s nothing sexual behind this contact.
In less that Rex could’ve ever predicted, Fives falls asleep, with his head on Rex’s shoulder, hands intertwined with Echo’s, who’s caressing his palms. The two look at each other just for a moment, then their gaze turns immediately towards Fives.
Rex can’t help but to feel guilty about this - he should’ve sensed it from the start. The least he can do now is to offer him all the support he needs, and hope that the next time he’ll actually talk to him instead of keeping everything inside.
“Mind if I take a nap too?”
“Go ahead,” Rex chuckles. Of course Echo would ask permission even for something like this.
After getting comfortable leaning against Fives, resting his head on his shoulder, even for Echo it doesn’t take long to fall asleep.
Rex can’t stop looking at them, his men, his lovers, and the more he looks the harder it is for him to fight the dumb smile off his face.
Actually, now that he thinks about it, Echo’s idea isn’t so bad. After all, this mission has been tiring.
Following his men’s example, then, Rex relaxes his body and closes his eyes; soon, he falls asleep too.
