Work Text:
It was supposed to be a good day off, with Mirage only needing, or better worded, wanting to get some new pieces.
Noah delivered, ordering them, and their arrival was just on his off day. Working for the government had its perks. Noah was under him, ignoring the blabbering that came out of the bot's vocalizer.
He was just adjusting the mod when he peeked into a compartment, something hidden directly under what he always assumed was Mirage's face module. Prying it open, out of curiosity, Mirage went dead silent when he discovered the shiny piece.
"Hey, Rage?" What does this do?" He tried circling around the hole that held the piece in, his curiosity got the best of him, and he traded the rim of it before being blinded by the light. He hit his head on the top of Mirage's alt form before bumping on it, and he felt his finger being enraptured by warmth. It felt like some type of slime on his finger, and suddenly Mirage was transforming away and pushing him back.
Mirage stared at him with still optics, pushing himself back and protectively covering his chest piece.
"I'm sorry, did I hurt you?" Noah lifted his hands in surrender, cleaning his nose briefly and folding his work sleeves. Mirage just shook his helm, staring back at him before deviating his sight to the floor and scurrying back.
"I am sorry?" Noah tried an expression of sadness before the bot shook his helm again.
"¡No! It's not that I'm-I just remembered I had to do something important. Be right back." Mirage said it so fast Noah almost didn't understand him, and in a few blinks he was driving out of the garage.
Odd, Noah thought, but no matter, he had the rest of the day for Criss and himself
...
Mirage fidgeted with desperation, balancing from one pede to the other as he hid himself in a dark, sole alleyway, a servo circling over his spark chamber. He tried touching it, dipping it in, but he just couldn't, and it was so frustrating, his big fingers didn’t fit, they just weren’t like Noah’s, he cursed in the dark of the night.
....
"What is it?" Noah asked while he had his welding mask on, working on a piece for a customer, mod’s weren’t his specialty, but this was a friend of a friend asking him for a custom.
The towering bot fidgeted like a little kid, leaning in and butting on him, utter chaos while he worked on such a delicate composition. Noah normally woulndn’t be annoyed at the cybertronian for wondering what he was doing, but this was surely a little exescesive, and when he shivered for the last time, Mirage didn't seem to notice how his vent system blowing cool air into the back of Noah's neck made him shiver.
"Alright. What's wrong?" Noah tried, dropping his tools and turning off the power source. He spun in his chair to look back at the bot, who now stared wide-eyed at him.
"No-no thing!" Mirage tried, but Noah was still staring at him like that. With a deep sigh, the bot tried to put his thoughts together, slowly coming up with something, anything, and failing horribly.
"Do you, ugh! remember when you were putting that mod in a few days ago... You touched something..."
"Yes..."
"Well, you touched my... Spark?" Mirage tried, but the human didn't understand that last word.
"Was that the shiny thing?"
"Yeah, you basically fingered my soul." Mirage gave an awkward laugh, but then it turned even more awkward, and Noah was looking at him, not even surprised, just expectant.
"What do you mean?" Noah tried, taking his gloves off and going to reach for a snack. Mirage couldn't help it; during the past week he just prayed that Noah didn't realize it, that he didn't notice it, but every time he felt his rough, padded hands, calloused and soft and meaty, he thought of them on his spark, how they would feel, how they were warm and cool at the same time, and how the rough texture would feel against his spark’s outer layers.
Would it sting for Noah? or feel pleasant to the touch as well? At last, Noah seemed to notice, motioning him to come closer, and while still munching on his cereal bar, motioned him to open his spark chamber.
"What? Right now? here?" Mirage questioned, looking around as if they weren't closed right now.
Noah nodded, motioning him to sit down on the floor and open them. Hesitant but equally aroused, Mirage sat down, leaning back a bit as the mechanic stood up, walking slowly to him and examining his seams. Noah nodded, slowly but surely tracing the seams on his armor carefully as he traced back to the circle that pulled away, that hid under his plating, and he witnessed his spark being exposed, bared completely and without regard to the humans' curious eyes.
Noah shook off his hands on his dusty pants, and Mirage screeched as he saw the human intent on bringing those dirty, dusty fingers onto his spark, the most fragile of his components, his spark.
Mirage almost closes his panels on Noah's fingers, probably snapping a few if he had, Noah, startled, stepping back.
"What?" he said, a little startled and defensive. Mirage mimicked clearing his throat; he found it soothing, even if bots didn't have to do it.
"Could you wash your hands and dry them at least? before... touching the most fragile of my components?" He tried; he didn't know why he felt so shy asking. Had Noah been another bot, he wouldn't have survived that unscathed.
"Oh, sorry, yeah, I'll get to that right away..." The human rushed to thoroughly rinse his organic servos; he dried them and shook them in the air before returning to Mirage, who, after seeing him again, a little refreshed, finally opened his spark chamber again. He watches anxiously as Noah focuses in on his spark, the glow of it radiating on his face.
Finally, a finger traces onto it, and, given his other warning, Mirage lets himself melt into the experience, moaning freely when Noah touches his spark with a finger, he really couldn’t help it, it felt good!
It is such a strange sensation; it is akin to charge peaking, merging, but nothing like it at all. Mirage grasped at the floor and moaned as Noah pressed in, making him quiver and separate his legs, cupping him closer so he could touch more.
"Are you really... getting turned on by this?" Noah questioned, and when Mirage looked back down, meeting his eyes, he was just as red and hot as Mirage, both looking at each other.
Mirage gave a weak, awkward nod, a strangled sound squeezed out of it as Noah smirked, his finger toying with the liquid stuff around his spark. It was blindsiding, and in no time Mirage was grasping at the floor, hips moving erratically, searching for a connection that he knew wasn't there, his optics rolled upwards, and before long he was overloading on Noah’s fingers.
Noah snapped back as the ticklish static hit him, enwrapping him and making him giggle as it seemed to go through him. Mirage went taut, hydraulics straining until finally he melted flush to the floor at last.
"You okay, 'Rage'?" Noah finally asked. Oh, he wouldn't be able to take the image of Mirage, massive as he was, overloading on his finger, optics rolling back his head, vocalizer glitching as he moaned.
Mirage gave a groan and sprang back to sitting immediately. He was making that face again, the one that told him he was about to say something awkward. While the human checked his finger, feeling the gooey stuff on it, he drew it to his mouth, tasting a bit of it. It tasted sweet and crackly like popping candy.
"Wait! Why did you-!?" Mirage panicked a bit when he saw him engulf his finger in his mouth, licking it clean. Just when he thought Mirage couldn't get redder or caught off guard like that. Suppose it takes one to know one.
"What? You think I didn't realize how you look at me when I'm working around shirtless, not very subtle, Mirage..." Noah said, playing it cool, but he couldn't help but sigh on the inside when Mirage confirmed by his expressions alone that he was right; it was hard to know if he was just imagining it, seeing the bot almost sweat, when bots didn’t sweat was enough to confirm his.
"You... Are you, what was the word Cris taught me the other day? , uncomfortable?" Mirage tried, nervously gesturing. Noah shakes his head, wondering how the bot in front of him had come to be so close, so intimate with him.
"How can I be when you look so good melting off my fingers?" Noah taunted, wriggling them for dramatic effect.
"Then... can we... do it again?" Mirage leaned to him, almost butting their heads together, looking absolutely excited.
"Again? hm..." Noah pushed him down to sit back, crawling over him.
"Can we?" Mirage looked too excited. If he had a dick, which he probably didn't, it would be rock hard for him right now. "Lay down and open up, but if you move, I'm pulling out and leaving you like that.
”Noah felt empowered when the big robot moved under him, staying dead still under his legs and opening his spark chamber.
"Please, please, please..." He tried, resisting the urge to flex his hips. Noah breathed slowly, trying to calm his excitement. Fuck if this ruined their friendship. Mirage really wanted him, and he Mirage.
Slowly, he straddled his middle, pulling the welding cover off his body and throwing it away. He unbuckled his belt and shook off his pants and underwear.
He sat down again, coming closer to his spark.
Noah leaned forward to kiss his jaw piece, all warm metal under his lips as he rooted forward, he spit on both his palms and rubbed them together, grabbing his dick in his hand and two fingers circling Mirage's spark chamber, only tracing the lines.
It was absolutely lewd and dirty for the bot.
Noah moaned against his jaw, resting his chin in as he urged his hips.
"Forward," Mirage whined, feeling the soft, warm skin over his chest armor. He was dead still, knowing how easy it would be to pinch Noah, to hurt the human, and then Noah pressed his finger in, and Mirage had to fight his own brain module to stay still.
The human dipped two fingers inside, grabbing a bit of the gooey liquid around it and rubbing it on his own dick. Human, organic, Noah was organic, right? Mirage reminded himself. Finally, and with a long whine, he felt the tip breach the outer layer slowly, and Noah was speechless over him; his spark shined even brighter, both of them melting on each other as the static seemed to circle them both. He felt something deep in his being, way better and more intense than spark merging, and he couldn't help but think he wanted to feel this euphoric all the time.
Noah thrusted inside, getting into a slow, grinding rhythm, and slowly falling into it, he went weak over the bot, both hands holding him up the bot, shaking uncontrollably as he thrusted inside and out.
Noah groaned, a deep growl that made him go taut.
"It feels so warm... I've never..." he tried, losing his voice as his thrust grew out of pace.
"Yeah... just like that, baby!" Mirage grasped at Noah's knees, pressing him harder against his frame and giving him more room to thrust in. A well-aimed thrust made the robot crackle with static. Suddenly there were stars in his optics as he gave worked breaths. He could feel something weird coming out of his park, like pulsations, that just grew until they had his whole frame shaking erratically, almost like convulsing.
Noah caressed his robotic face, watching the robot under him convulse in ecstasy until he fell unmoving, still on the cold garage floor. Noah pulled out as the robot took his time to collect himself, rebooting, most likely. He licked at his own palm, reaching for his hard, red-tipped dick and thrusting it into his hand, forming a tight circle and thrusting into it. He moaned and whined, calling for Mirage before finally spurting a tight line just on Mirage's spark. His cum floated slowly into the tight circle of energy. Just as he kept milking his dick, red from the friction, and fully enjoying the thickness of Mirage's Spark lubricant, his dick drawing up tight with a contraction and spurting another two lines into his Spark, it dawned on him.
Noah sweated cold as he looked at his seed sinking slowly into the spinning system of inner particles of Mirage's spark.
Did he just come into his partner's soul? Mirage looked out of it, hips thrusting into nothing, plating swollen under the panel covers; it leaked transfusion pink onto the floor from the side.
He kept rubbing against his plating on the floor, thrusting slow circles into the air. After finally calming down, both of them, Noah hoped Mirage wouldn't notice, but just as he was going in for a kiss...
"Did you... inside?" Mirage said, with hot faceplates.
"I'm sorry, I did." Noah got red all over, embarrassed as he looked down to the floor.
"No! No, I-I-I-I like it; it's just that I can feel it inside." Mirage swung his front from side to side, enjoying the fullness of its heaviness, just on his spark.
"Clean up time; get up and sit for me, baby..." Noah muttered, after a while, giving a quick peck to Mirage's cheek
…
"Hey Noah, I feel kind of weird. I might need to go over to Ratchet's base over on Detroit..." Mirage tried, clutching at his chest.
"But you have a mission on Friday; you can't leave," Noah reminded Mirage with a scowl.
"Oh, that 's right. Well, no matter, I'll go later..."
…
"Oh, fuck!" Mirage clutched at his chest, knee joints giving way under his feet as he fell to the garage floor.
"What's wrong?" Noah tried.
"Does it hurt? where?"
“It feels weird..." Mirage muttered, not letting go of his chest plating. Noah was quick to turn on his headlamp and instruct Mirage to lie down.
"Let me see, come on, open for me, baby," Noah said, trying to comfort Mirage. Instead, Mirage gave a weak sound and opened immediately.
The human leaned in, kneeling at his lower chest. Noah shined around his spark chamber, checking for anything out of the ordinary, any faulty piece, but everything was normal, or looked normal at least.
"If only we had a scanner like Optimus does..." Noah said between his teeth.
…
"Noah, I think I know what's wrong with my frame, and we'll need a bigger garage..." he said, fingers put against each other in a nervous manner. He was red in the cheeks, and he looked like he was hiding something.
"What? But this garage is perfect. It's spacious and—and—what is it?" Noah crossed his arms, awaiting a clear answer.
"I'm sparked." Mirage said, barely containing his anxiety, fear, and excitement. "What's that?" Noah suddenly looked deeply concerned.
"I'm... pregnant...?" Mirage tried, still nervous.
Noah dropped the key he had in his hand, mouth agape in surprise.
