Upgrades and Experiments

Summary:

Echo can't feel a hand on his skin, forget the ground beneath his metal feet. The latter causes issues in the field to the point Tech notices and offers to fix it... The latter and the former issues...
...and Crosshair is more than happy to assist Tech in his experiments to ensure the upgrade program he builds Echo is perfectly functional and pleasurable.

Made for The Bad Batch Holiday Exchange 2025

Notes:

Written for The Bad Batch Holiday Exchange 2025 and specifically for letshareapapou (both on tumblr)

Characters/Relationship: Tech/Echo/Crosshair
Prompt: Wireplay (seen here as programming-play), Crosshair submission to Tech, established CrossTech, First time (in this body)

Work Text:

Once was ignorable.

Twice and Crosshair was sassing him through the com line.

Wrecker picked him up after the third one with a playful pat on the back.

Hunter was lingering nearby after the fourth.

He was doomed after the fifth.

"Echo, the balance sensors on your prosthetic legs are faulty and in need of repair." Tech offered his hand to help him up and back under the cover of a nearby log.

"I'm fine, Tech." He put all his effort into the smooth delivery. Internally he was shaking like a leaf in a storm. "The underbrush is just a bit thick."

"This's nothin'!" Wrecker boomed through the com line. "You should've seen the other places we've been!"

"It is true," Tech's sharp eyes were looking him over; without the cover of a visor it was hard to ignore the strength of his gaze. "We are often in the field and crossing difficult terrain. If this is too thick, I will have to recalibrate your sensors."

"If you're all quite done chatting…" Hunter's voice strained through the line, "we have a mission to complete."

"Yes, sir. On it, sir." Echo moved out of cover and to the next point.

Just one foot in front of the other. Let the servos keep him up right and not overthink it. He had to make it through. He couldn't survive all what the Techno Union did to him just to fail at running on uneven ground.

He had to make it. He couldn't be decommissioned now.

Echo couldn't feel the ground, just the looming presence of gravity and had to have some faith. Trust in the Force and all that osik.

Just one foot in front of the-

 

Echo woke up on his bunk.

At the edges of his senses was pressure along his thighs. Deep, heavy, and warm pressure that coaxed an internal warmth out of him. Shifting up onto his elbows he discovered the source of the pressure; Crosshair was passed out in his lap. Sitting on the floor but leaning forward to doze across what remained of Echo's thighs.

When was the last time he was really touched? More than just for a medical exam or because he needed to be helped? Touch for the sake of touch?

More of that delicious heat poured into Echo's core, as if Crosshair's own warmth was flowing into him. On baited breath Echo didn't move, just watched the dozing sniper continue to breathe warm air into his lap. He could actually feel it.

Maybe whatever happened when he was passed out fixed him? Could he be that lucky?

Cautiously Echo pressed his sole hand to his chest and his heart sank. The only touch his body felt was from his palm, there was just a void from his chest. Pressing harder he started to feel something but it was vague and distant.

Crosshair shifted, that heavy pressure and warmth moving in his lap. At least Echo could feel that, granted it took nearly all of Crosshair's weight and warmth to make a difference but it was real and it was here. Before Echo could stop himself his hand was in Crosshair's short silver hair; slowly and gently scratching along his scalp.

"Don't do it again, Reg." A snarl from the sleepy sniper, golden eyes giving a single glare before closing and resettling himself.

Echo immediately withdrew his hand. It was no secret that Crosshair was Tech's and that was to be respected. He was wrong to give such a gentle and intimate touch to him.

"He is referring to tripping over the underbrush for the sixth time and hitting your head on a tree which caused a minor concussion and loss of consciousness." Tech appeared overhead, shifting his goggles. "He is awake, you may move now."

"Ask." Crosshair made no action towards moving.

Tech's eyebrows lifted above the goggles, a daring glare gleaming through the yellow lenses.

Crosshair only shifted to be more in Echo's lap and reiterated his statement with his trademark hiss. "Ask."

Echo immediately mentally began to recite the codes for cleaning barracks. Whatever was going on between Tech and Crosshair at this moment didn't involve him and he couldn't let himself show any preference towards Crosshair without getting himself in more trouble with Tech.

Overhead, Tech sighed while rolling his eyes. "Echo, may I have your permission to repair the pressure and balance sensors on your legs so you are able to navigate uneven and otherwise difficult terrain with ease?"

His response was cut in his throat by the warm breath that mirrored the pleased purr from Crosshair. Echo's internal system alerted to the spike in his heart rate- as if he didn't feel it pounding in his chest. Whatever game he was playing Echo for, he hoped Crosshair would stop so he wouldn't catch Tech's ire.

"Are you experiencing issues with your auditory processing capabilities following your concussion and loss of consciousness?"

"N-no" Echo stammered out between heartbeats. "If you think that is for the best, Tech, then sure."

"I would not suggest something that is not 'for the best.'" The engineer scoffed at the thought, nudging Crosshair with his boot. "He gave his consent, you can move now."

Crosshair slowly lifted away from Echo, it had to be a coincidence that his hands dragged across him. A part of his mind didn't agree with that- his pressure with the drag path was too strong to be anything but deliberate and the lingering glance didn't help.

"I will remove your prosthetics now." Tech's tone and words drained all the warmth Crosshair had pooled into him. "I expect to return them to you prior to our arrival on Kamino. I have tasked Crosshair to be at your side and get you whatever you need until I return your legs to you. Do you find this satisfactory?"

"Y-yeah…" Echo couldn't help the warmth that pooled back into him despite the unease of having his legs removed.

Tech was letting his Crosshair be in Echo's space. If that wasn't an outright declaration that Tech truly accepted him as one of the Batch, Echo didn't know what was.

Crosshair watched Tech carefully disengage the legs and gently pull them away. Echo tried not to flinch as the warnings popped up at removal of each limb. He quieted them in his neural network and breathed through it.

Just breathe… he could get through it. He would get through it.

A pressure returned to his thigh, warm and heavy. Crosshair had returned to his position on the floor next to his bunk. Instead of laying across him, it was his hand pressing into his thigh. A sideways glance, the flick of the ever-present toothpick, and a smirk on those thin lips….

Echo returned to mentally reciting the reg manuals. Anything to try and tamp down the tightness in his lowers blacks.

❇ ~ ❇ ~ ❇

Tech made good on his promise. Echo was back on his metal feet prior to dropping out of hyperspace over Kamino. Still Crosshair lingered in his shadow, a watchful eye as Echo finally stood after long hours of being stuck on his bunk.

"The hardware is implemented but I have not yet finished the programming for it." Tech cautiously supported Echo by his mechanical elbow. "You should feel a better balance sensor already though, that was just an upgrade to the existing code and hardware framework."

"It feels better, Tech." Each step was more responsive and stable under him. He still couldn't feel the Marauder beneath him, but there was a noticeable improvement to the minor automatic adjustments his metal knees and ankles did to keep him upright.

A faint smile on the genius's face, blink and you miss it. "I am glad, I will have the programming complete before tomorrow. I am sure of it."

"Really, don't rush or push yourself."

"Nonsense," Tech argued back, "I am only doing my duties as the engineer and ensuring all of our gear is ready and repaired."

"Right… gear…" Echo's legs were not a piece of him, but rather just a piece of his armor to repair to Tech. A reminder that he wasn't whole, that parts of him were removed and these additions were temporary and removable fixtures.

Crosshair shoulder checked Echo on his way past towards the cockpit. "Don't overthink it, Reg. Let him work. You'll like it."

Echo's new legs immediately responded to catch him, balancing him perfectly where before he would have ended up on his face. Still, Tech had moved to catch him; the grip on his metal elbow tightening and Tech's arm reaching across his chest to stabilize him.

Echo's brown eyes met Tech's, his breath coming fast for many reasons. "I think they work." Echo tried to laugh but it was breathy and rushed.

"Of…Of course they work. I repaired them." Tech's eyes darted away, like his arms, while his face reddened. "Please prepare for landing," and like that, he was swiftly moving to the cockpit and away from Echo.

Echo's heart rate alarm triggered again, he just had to be seeing things. Tech was probably blushing at what Crosshair had said or something. He couldn't have caused that. Tech had Crosshair… and Echo needed to stay out of it.

❇ ~ ❇ ~ ❇

Echo focused on breathing. In and out in even and consistent intervals despite the alerts that were being triggered internally. Tech was slotting in the new programming for pressure sensors for his legs into his neural network and the intrusion was difficult. The protective walls Echo had spent time building in his mind to prevent another invasive intrusion like the Algorithm was now fighting against Tech.

The engineer had his datapad plugged into his legs and was muttering complaints under his breath. The words 'rudimentary' and 'pathetic' floated to Echo's ears from his clipped tone.

The weight in his gut flipped over, it wasn't as if Echo was specially made to think like a super computer like some people. Echo held his tongue though, trying to reduce his mental walls so Tech could just get on with this and leave him be.

All at once feeling crashed into him as if the Kaminoan sea had broken through the barrack window. Immediately overstimulated it was his automatic system breathing for him as Echo swam through all the new senses.

Tech's fingers were brushing against his left knee, pulling away one of the connector cords. One of Tech's knees was nearly overtop of his foot. There was no heat with these senses but the pressure was there, Tech was there.

But most of all, what had Echo on the brink of tears, was the floor. He could feel the ground beneath his metal feet, solid and strong.

"Breathe, Reg." Crosshair's hand pressed into his shoulder. He had been watching Tech work from his bunk but now he loomed over Echo.

Tech scoffed from his knelt position. "He is breathing."

Crosshair's golden eyes consumed Echo's swimming vision. "He needs to breathe, not his systems." Long fingers firmly held his jaw, lifting it to meet Crosshair's. "Breathe for us, Reg."

Somewhere distantly Echo heard Tech complain about not giving Echo enough space for breath but that close to the sniper- all of his attention was on the few points of contact they shared and his warm breath on his skin.

Every breath out for Crosshair was a breath in for Echo. In and out they shared breaths until the new senses settled and Echo came back into himself. A version of himself that wished that the few inches between them were nothing at all.

That singular thought burnt the contact points with guilt. Painfully Echo ripped himself out of Crosshair's grasp.

"Are your pressure sensors satisfactory?" Tech seemed indifferent about the proximity and the none the wiser of Echo's thoughts.

"They work." Experimentally, he lifted his heel from the floor and was soothed by the increase of pressure at the ball of his foot. "Exceptionally well, Tech."

Tech offered another one of his small and quick smiles before nudging Crosshair out of the way. "I will now test the full range of the sensors. Please alert me of any zones of inactivity or unsatisfactory pressure information relay."

That was all the pretense Echo got before his right leg was grabbed and pulled into Tech's lap. He was about to protest something metal shouldn't be in such a sensitive spot- but Tech's fingers floating over his metal calf stopped the words short.

'The finest legs in the GAR.' Fives stroked up his calf following the trail of kisses he left in Echo's skin.

Echo panted under his touch, 'We're clones, all of our legs are the same.' Something- anything to try and stop the onslaught of teasing Fives was putting him through.

Fives chuckled against his thigh, goatee scratching into sensitive skin. 'No Echo, to me you are unique in every way.'

Echo was pulled sharply out of the memory by the sharp change of sensation at his thigh. Tech's featherlight fingers that were loud against his metal skin were now absent from his thighs only covered by his thin lower blacks. The change of sensation pulled a sorrowful sound from his throat before he could stop it.

"Are you not satisfied by the pressure sensors?" Tech queried, hand still light on his thigh.

"No, they-" Echo took a breath and calmed himself. "They're great, Tech. Thanks."

Tech only cocked his head and furrowed his brow. "Then why are you making an upset expression?"

Internally he sighed, there was no way around this. Tech would bully the answer out of him if he didn't give it willingly. The engineer was persistent when it came to information and data. Nothing would stop his pursuit of knowledge.

Echo crossed his arms over his chest, something to try and hold himself together through this. "The legs sensors are great Tech- really they are…"

"But…" Brown eyes behind yellow lenses bore into him, leaving no room to hide.

"… It's not the legs, its me." Echo held himself tighter to feel the pressure of it. "I'm the one that can't feel anything."

Tech blanched, drawing back from Echo. "Your file noted that sensory feeling was returned to satisfactory values. Has this changed due to your recent concussion?"

Crosshair groaned, "It was satisfactory to the Kaminoans, not him."

Echo nodded an agreement, "Only sensation in my hand was fully repaired. Can't exactly shoot straight if I can't feel the blaster in my hand." Quietly he laughed, hollow and sorrowful. A sound to soothe himself more than lighten the mood.

"Would you like me to fix that?"

Echo blanched now. "You can do that?" It felt like Tech had asked if Echo wanted a ration bar- not to repair the part of him that was left most broken.

Tech for his part pursed his lips and thought carefully for a long moment before answering. Maybe he had offered something too quickly or in jest. Echo hadn't known him to be so careless in offering though, and waited with careful hope for his response.

"I can," Tech finally said, his hand returning to Echo's thigh, the metal part where he could feel it clearly. "It will take time but if you desire sensory feeling in your body I can make that happen."

Echo sucked in a breath as that hope filled him completely. "I can't thank you enough."

Nearby Crosshair chuckled to himself, "You have no idea what you're getting into."

But Echo did, he was getting his body back. His feeling back. If it anything like what Tech had done with his legs, he would be more than happy.

❇ ~ ❇ ~ ❇

They were deployed out quickly into two back to back missions that left Echo with little time to think about Tech's promised improvement. The improvements Tech had already given him was the focus of his mind instead. Echo found himself thankful of the simple ability to feel the solidness of the ground beneath his metal feet.

He didn't trip once, despite the uneven ground and underbrush they tore through at breakneck speeds. Echo actually laughed while keeping pace with Crosshair. He didn't have the burning ache of his legs or lungs to hinder the pure thrill of feet pounding into the dirt and the grasses dragging across the exposed part of his knees. He almost wished he didn't put on the protective casing to his legs to feel the grass better. He couldn't feel the wind but he could imagine it.

The update Tech has will give you that feeling, surely it will.

Echo smiled under his helmet and continued running back towards the Marauder with Crosshair at his side. Carefully, Echo pressed himself harder, sneaking ahead of the Batch's best runner.

"Don't-" Crosshair was breathing hard through the com line. "Don't you do it."

Echo just laughed at the threat and extended the gap. Let Crosshair be mad a reg beat him for once.

❇ ~ ❇ ~ ❇

Echo walked out of the Batch's private 'fresher pleasantly warm. He always waited until the rest of his brothers were out in their post mission activities before finally showing himself. The process was long due to the mechanical part of it, doubly so since Echo would sit under the water set to the warmest and strongest setting until fingers pruned. He didn't want to put the 'fresher off limits to the others for that long… that's the reason why he always waited.

It definitely wasn't because his cybernetic riddled body was on display afterwards. He definitely wasn't ashamed of the metal that jutted from his paled skin.

Wrapped in a towel, Echo made his way to his corner of the barracks. He needed to apply the bacta infused lotion the medics had given him for his skin. The areas that kissed the metal implants was fragile and needed special attention that was too rarely given when out on missions. He really only allowed himself time to properly care for them while in the safety and privacy of these small times when he was alone in the barracks.

… The jar of salve was not in his trunk as normal. Could he have misplaced it after the last time?

"Looking for this, Reg?" Crosshair drawled from his bunk, the jar in his open palm.

"Cross- what are you doing here?" He pulled the towel higher up to try and cover the central circuitry he found the most alarming in the mirror to look at.

"Finished practice early." That damn toothpick flipped from one side of his mouth to the other, Echo's eyes following it.

"Give me the jar."

"Or what?"

Echo didn't know. He was at a severe disadvantage in just a towel if it came down to actually fighting for the jar. Honestly the thought of any physical closeness with Crosshair in this current state made his core tighten.

"Fine, keep it." Voice tight he turned away and retreated towards his corner again. The bacta gel alone would do in a pinch, he could get the salve jar later. He had to keep distance between them, be respectful of-

"I thought they taught regs better than to turn your back on a threat." Crosshair pinned him to the wall, his breath hot along the back of his neck. "At least the ARCs should know better."

This was not helping his resolve. "I-I didn't know you were a threat to me." Remain neutral. Respectful of the established relationships.

Crosshair's hands pressed into Echo's sides as his body pressed him flat to the wall. "Depends on what you consider a threat." Echo couldn't feel the lips fluttering across his neck, but the warm breath he could feel.

A threat to his self control. A self control that was weakening with what became obvious open mouth kisses to his exposed neck and shoulders. Crosshair was doing his best to apply as much pressure as he could to them, as if he had always been aware of Echo's lack of sensitivities when Tech hadn't.

A voice cleared behind them.

Echo stiffened and sobered up from the heat Crosshair had been dumping into his core. He would have removed himself from the compromising position of being squished between body and wall… if Crosshair would move. The sniper had stopped his assault on Echo's neck but refused to move away.

"I am disappointed."

Guilt burned into every place Crosshair had kissed as recognition dawned on Echo. The voice belonged to Tech.

"I-I-" Echo couldn't form a good excuse, he hadn't asked for this but he should have stopped this. Put his foot down.

"He didn't tell me no." Crosshair practically purred across his neck.

"You expect me to ask for consent and yet do not hold yourself to the same expectations and standards." Tech was cross at Crosshair, not Echo. "I understand your impatience for this experiment but you will ruin the data set with this behavior."

Crosshair pressed three more unhurried kisses to Echo before finally peeling his body away from him. Echo was shaky on his metal legs, as much as he didn't want to be. It had been far too long since he was put in this lust drunk state. He turned around to put the wall at his back and inspect the engineer.

Tech was accosting Crosshair at length, namely about consent, variables, and data purity. None of his anger was pointed at Echo. At least that's a positive in all this. He got a taste of pleasure for a moment, maybe he could use it to pull something out of his body quietly in the night. A hard task since the normally overly sensitive length couldn't get hard when barely any feeling was registered by it or the rest of his body.

"Echo," Tech's call snapped him to attention and beckoned him forward, "are you still interested in the body sensory improvement?"

"Of course." If nothing else it would assist in helping those middle of the night private sessions with himself.

"I am glad, I thought Crosshair's actions without prior explicit consent as a new partner would turn you away from such activities."

"New partner?" Tech couldn't be implying- "What does restoring feeling have to do with…" Even speaking it aloud, saying Crosshair could be a sexual partner felt wrong with the guilt still burning holes in his skin.

Tech for his part only looked confused. "Why else would you want such a program to restore feeling to your body if not engage in intercourse with us? There is no better feeling that can be felt based on hormonal and chemical exchanges that occur during such activities and you have shown. You have shown preferences to our space and companionship, is it not us you wish to engage with?"

"Us?" How many loops could Tech throw him through in a row? He was a mess of metal, inside and out. He couldn't possibly be comfortable to be with.

And yet…

Crosshair silently appeared at his back, warm hands pressing into his sides with just enough pressure that it registered. "Don't over think it, Reg." The words breathed under his headpiece. "Let Tech work, it will be enjoyable for both of us."

If Echo had any lingering doubts on Crosshair's unease with his implants, they were promptly wiped away as his hands wandered shamelessly across the many ports that littered his torso. There wasn't a hint of unease in his touch, if anything the sniper was lingering around them. Testing the sensitivity of the scarred skin and metal.

"You are poisoning my data set." Tech grumbled on his approach.

"What a shame." Echo shivered under the heat of his breath and words.

Tech peeled Crosshair's hands away from Echo to unceremoniously cage the ARC trooper into his own arms. Not tightly, just sheltering away from the continued onslaught of Crosshair's advances. "Are you consenting to this arrangement and partnership? It is polite and wholly appropriate," he glared at Crosshair, "to receive clear verbal consent prior to any such activities."

Enough bad things had happened in Echo's short life to look any Force-given boon too closely, he agreed immediately.

And that's how he wound up in Crosshair's bunk between engineer and sniper. Tech at his back, supporting and cradling him between steady arms and legs; Crosshair in his lap, doing whatever Tech instructed, and more.

It was a prototype program, Tech had barely called it an Alpha status build. He had forced Echo to remove his headpiece, "I do not need you out thinking my programming," the excuse he gave. He had to run it off his datapad, wires connecting the treasured device directly to Echo's central circuity panel. That panel had direct override access to his heart and lungs, the amount of power Tech currently held over Echo's literal life was not unnoticed… but it also left him breathless in a pleasant and needy way.

Tech's blacks were warm against his naked body. "This is an experiment on the functionality of the program and your body. I will not be a variable in it." Words cold and clipped… but still leaving Echo wanting. Tech watched him like a show, a calculating eye that focused on each shiver and gasp.

If Echo was the show, Tech was the director of it. His neutral tone of directions to the sniper lit a fire of anticipation inside Echo's core. Crosshair had stripped off his upper blacks, Tech had protested until Echo had all but melted with the feeling of Crosshair's chest along his thighs.

Now Echo was splayed across Tech's front at Crosshair's mercy. Tech's program tracked a special set of gloves Crosshair wore along his skin, passing simulated stimuli to the processing center of his brain. Tech had to manually set the pressure but it was still heavenly. Echo was breathless mess with just Crosshair's wandering hands and heady kisses laid into what remained of his thighs.

That isn't to say the sniper stayed away from his metal legs. No, he teased that connection point. Threading the line between perfectly programmed pressure sensors and the simulated senses Tech was orchestrating.

For the first time in this body, Echo was fully hard, and Crosshair had yet to actually touch the needy length. Tech ordered him not to, repeatedly.

Crosshair took offense to the restriction and laid more open and heavy kisses into Echo's thighs and lower body. His mouth wandering away while his precise hands diligently obeyed Tech's commands. The combination was a fire in Echo's core.

"You may begin," Tech breathed across Echo's neck… maybe he was kissing him but too softly for Echo to really feel outside of the warm wetness that was seeping into his awareness.

Cross immediately dipped his head towards Echo's length at the command- only to have his hair caught in Tech's free hand.

"We are not yet at that data set. Patience or you will be excluded for data poisoning."

Echo should have been turned off with how much he was an object to Tech's scientific study. Probably to anyone else he would have been, but the controlled tone and Crosshair's grumpy submission only increased his arousal. Whatever Tech wanted to do, Echo was willing to relent to if it meant continuing to be this breathless and full of fire and feeling.

That fire burned white hot and left him gasping as Crosshair took his cock in hand.

Inexplicably, his arousal and sensation dulled immediately. A peak at the datapad in Tech's hand explained why, he artificially turned it down.

"We can not have you ending this experiment too early." Tech whispered in his exposed ear, "I have data to collect still."

Echo's entire body was at Tech's disposal; vitals, hormones, sensations- all laid out in careful charts and data points on the screen. All able to be manipulated with just a touch of his finger.

Echo shivered as he visibly watched his arousal state increase on the graph despite it all.

"Fascinating…" Tech's voice was a touch breathless and he pressed a few heavy kisses into already bruising skin.

Echo's attention was brought back to his lap as Crosshair's hand returned to his cock. This time glove-less and slicked with warmed lube. He was applying firm but gentle pressure with his languid strokes, just enough to feel but still distant. The warmth of skin was the true bliss point of the action.

"That is not what we discussed, Crosshair." The engineer was back to clipped and neutral for his scolding.

Echo's hand latched into Tech's free one. "Please," a beg as he turned to try and look Tech in the eyes. He needed this, he needed the raw feeling of skin against him.

Tech relented with a soft and chaste kiss to Echo's mouth. "I do not tolerate deviations often. Since it is your first time with us, I will allow for some flexibility. Do not expect to always have your way."

Crosshair hid an amused laugh in a kiss to Echo's thigh, never stopping his even strokes.

"Keep that pace, Crosshair." Tech directed as he returned to his position of looking over Echo's shoulder, applying small kisses and nibbles into the flesh under his mouth.

Echo could only breathe and relent to the new onslaught as Tech manually sent the simulated strokes to his system. It was not perfect, slightly out of sync but it only made Echo breathless and needy that much quicker. Left hand gripping Tech's, his right hand automatically reached out towards Crosshair before he knew any better.

Watching the scomp approach Crosshair's face sobered him enough to try and draw back, he wouldn't submit Crosshair to that kind of touch. Before Echo could fully pull back though, Crosshair had taken the tip of scomp in his mouth. Hunger in his golden gaze that locked tight to Echo. His strokes of his cock now matched with long drags of his tongue along the metal fixture.

Echo in Tech's lap with wires connected to his central circuits connected to Tech's datapad while Crosshair is in Echo's lap hand on his dick and mouth on his scomp. Echo is naked, Tech in full blacks, and Crosshair in only his lowers. - all three are in Crosshair's bunk

Echo was reduced to whimpers between them. Echo opened his mouth and a moan came out with Crosshair's name. The sniper's eyes had been dancing between Echo's and Tech's, but now firmly locked on the ARC trooper. Echo needed him, needed to feel that deep pressure he was constantly applying.

"Cross- please," Tech's previous warning forgotten, "C'mere, I need you."

Tech pulled away from his shoulder but Crosshair immediately slithered up to Echo's face, "Whatever the Reg wants…" he murmured with a smirking smile. Crosshair pressed a kiss along Tech's jaw over Echo's shoulder, squishing him between sniper and engineer. "You said this was for him and not me after all."

Just how much had they discussed about this encounter before hand?

"You know well that is not what I meant." Tech was frustrated, but it was hard to dwell on that when Crosshair's weight on him included what had to be his own hard arousal pressing along his groin.

"Then be more specific with your words." Crosshair now pressed kisses on Echo's jaw. "I'm just following orders."

Whatever orders Tech tried to give was lost to the flurry of kisses Crosshair pressed into Echo. Biting at his lips and tasting his tongue; kissing Crosshair was heady and nearly feral with want.

The datapad with the program had been pushed aside so Crosshair could meld against Echo's body but at some point Tech got a visual angle on it again and the program started anew. This time there was no connection to Crosshair's deep pressure wandering hands, this was stimuli wherever Tech wanted it to be. The new sensations had Echo arching up into Crosshair, pressing their cocks together and grinding his ass back into Tech's lap.

"Tech-" Echo panted practically into Crosshair's mouth, "what- what are you doing?"

"Is it not pleasurable to have more simulated points of contact?" Tech's tone was casual, as if asking the weather and not sending waves of pleasure through Echo's body. "Should I keep it to just what is being touched?"

Crosshair ground his hips along Echo's his bare length rubbing in delicious friction, however distant it was, with Crosshair's clothed one.

"No…" Echo breathed as Crosshair repeated the action and Tech worked magic on the program, "you can do as you want." Anything to keep this going…

Crosshair chuckled against his ear, "Now you're catching on, that's the best thing to do." He pressed his cock again against Echo's savoring the feeling himself. "He has yet to disappoint in his 'experimentations.'"

As if that was the magic key to Tech's involvement, the admission of complete free reign to his body; Tech freed his hand from Echo's grasp to press between sniper and ARC. Precise fingers pulled Crosshair's cock out of his lowers and take it in hand with Echo's. Immediately the sensations synced up and Echo pulled Tech's head tight to his shoulder as he gasped under the new sensations.

As much as he wanted to let this go on, to stay firmly the object of desire of these two… it was all too much. Crosshair's heady kisses, his cock firmly pressed along his own, Tech's hand and program working in tandem- it was a deadly combination he was powerless against.

Echo fell into his orgasm with a desperate sound that Crosshair swallowed. Tech's hand did not relent, continuing to stroke both of them until Crosshair moaned his own release into Echo's mouth and also spilled into Tech's hand.

Breathing hard, Echo relaxed backwards against Tech with Crosshair pressing into him from above. He couldn't remember exactly what it felt like before but it surly felt this good too; warm, calmed and content. Carefully, Tech eased himself out of from behind Echo despite the protests from both sniper and ARC. He let them both stay snuggled on the bunk, continuing to come down from their bliss high.

Completely horizontal, Crosshair took the chance to lay across Echo, blanketing him with his long body. Echo eased into the grounding pressure. He wasn't sure when Crosshair had noticed he needed pressure but he would forever be thankful.

Slowly his mind cleared enough to realize an oversight. Tech hadn't finished and was now sitting at the table looking over his datapad as if nothing had occurred.

Noticing the gaze that lingered on him, Tech caught Echo's eyes. "Do not trouble yourself. Crosshair will assist me later with my own needs. For now, you need rest and grounding pressure. Rest with him while I catalog this data and make adjustments for next time and the next set of variables."

Echo swallowed hard, "Next time?" it was squeaky. He while he hoped it wasn't a one time thing, he had prepared himself to be okay with that.

Crosshair left a trail of soft kisses to his ear, "Oh yes." His characteristic hiss a whisper for just him. "Science requires lots of data and repeated experiments, Echo. What lucky lab rats we are."

Carefully Crosshair drew back and pressed a softer, chaste kiss to Echo's lips. Not desperate nor needy, but reassuring and affirming. His golden eyes holding that same softness in this singular moment. There was no sass or snark in his voice. His words were as soft as his actions.

This wasn't a fluke, or just an experiment with no feeling. Echo belonged between them, and was cherished; ports, prosthetics, wires, and all. They were here, they were real, and there was a silent promise for Echo to stay.

Echo pulled Crosshair closer, returning that softer kiss back. "Oh how lucky indeed…"

Notes:

I have some more ideas for this trio and the possible other experiments Tech has to continue the dev process and data collection of Echo's new upgrades... <.<
I enjoyed writing and making this piece and hope to expand on the idea more eventually <3

I hope your holiday season is bright letshareapapou <3
