A frame shifter, let alone one with such an extensive family history of Warframes having a child with the descendant of an insecticon was considered bad luck. It was also illegal due to the restrictions put in place on both of them, however, one such instance fell through, and a very peculiar child was born. This story, however, is not about that time. Instead, it is about the child, fully grown, and their less than normal experiences.
"Lord Megatron!" Shockwave was practically yelping around the fingers pressing into his neck and collarbones, rubbing softly.
Megatron's other hand was currently occupied elsewhere. His thumb was pressing on Shockwave's swollen node, index gently rubbing over the plump lips of his valve, and the rest of his fingers were tucked neatly inside, lubricant dripping over the barely exposed knuckle joints and down onto the floor in a lazy waterfall. "Easy now, you've been so utterly loyal to me, you really do need a prize."
"A - aaahn.... it is... it is my duty..."
Megatron pressed hard on the node, and Shockwave's legs gave out, nearly sending him to the floor, had he not been holding himself upright on a table.
"Yes, and for you my dear, it is a duty I wish to relieve you of. At least for tonight."
"Nnnh.. I-"
"Hush, I'll take care of you. You've nothing to fear."
Shockwave whined lowly as Megatron slipped his hand free, the emptiness was quite honestly depressing after the pleasant stimulation. He did not remain empty for long though, because almost as soon as he was, he could feel Megatron's spike pressing against his valve, nudging him softly but incessantly. He gasped and arched his back, only for Megatron's big, strong, rugged hands to gently manipulate his form to the most comfortable position for them both.
Then Megatron practically shoved himself inside, snapping their hips together sharply.
"Aaaah! My liege!" Shockwave gasped and threw his head back.
He was so full it almost hurt, straddling the line between pain and pleasure until it was a blur, he was panting, arching his back slightly, leaning into his liege and pressing his helm to the crook of Megatron's neck. They were practically gazing into one another's optics now. Shockwave's form was slick with sweat, and he was heaving with ragged breaths.
"Look at you Shockwave, so loyal. You are so good to me."
There was pressure on his abdomen, and he tilted his helm to look, antlers canting forward as he realized the pressure came from Megatron's hand, rubbing over the swollen bulge his spike made. Shockwave gasped softly and brought a clawed hand to meet his lord's. His protoform was stretched, and he had the faintest ping of warnings in the corners of his HUD. Internals shifting, warnings about the state of his baffles.
"My liege... I - I... oof."
"Are you hurt Shockwave?" Megatron gently kissed his neck and he whimpered.
"Full..."
"Ah," Megatron gently rubbed his thumb over the swell, "do you want me to stop? This is a reward after all, and I wouldn't want to hurt you."
"No! No... please, keep going. I will adjust, please..."
The warlord smiled, nodding, and he gently repositioned them, so Shockwave was resting on his knees, but his arms were bracing him on the table, and Megatron was behind him, if all else failed and he collapsed. He then began a rhythm, slowly at first, and as Shockwave seemed to adjust, he began to speed up, purring sweet nothings against his loyal followers audial. Shockwave was panting and fully allowing the motions of his master to jolt him, and he gouged the table with his claws, embarrassed, but so very happy.
"Lord Megatron... nngh.. m - my baffles, they-"
"Are of less certainty? You're worried about kindling? I suppose I don't blame you."
Shockwave panted softly, just barely at the edge now with how quickly his master had been moving, and how intense the stimulation of stretching was on his end. "I am less worried for my sake, if I did not want them, I could terminate them, if I wanted them, then I would raise them myself. I am just-"
"Are you worried I would not want them?"
The tank looked bashful and turned his helm, afraid to admit that was the truth, he was. He was very worried that his liege wouldn't want their spawn.
"Oh Shockwave, you've always been so good to me, any young we conceive would be welcome with open arms."
"B - but I am not... I am not like you. Don't you remember? My own parents could not keep me because of what I was, I would hate for you to lose them."
Megatron's gaze became soft, in the way that not many Decepticons - and certainly no human scum or Autobots - had ever seen before. His eyes no longer glinted with power, but became softer and sensitive, and his almost perpetual smirk instead became a warm smile. His hand brushed over Shockwave's belly once more and the tank whined. "You have nothing to be afraid of my love, I assure you. Would you like to attempt a kindling? The worst case is that we need to try again."
"I - Oh Megatron, yes. I would like that very much."
A nod, and he was suddenly once again subjected to Megatron's pace. It was bordering on brutal, but he was ready, panting as his liege thrust into him, one hand rubbing the small of his back, and the other still cradling the spike bulge of his abdomen. Shockwave could hear Megatron panting and groaning behind him, and an involuntary moan slipped from him at the sounds.
This had been, for so long, a fantasy of his. Not just the sex, but the sex was amazing. But having a relationship, however intimate, with his lord. A dirty, filthy secret he gratified himself to at night on Cybertron. Late, after he was finished with his duties as Longarm, and after he and Megatron were done relaying information he'd gathered, he would spread his legs and multitask. One hand, gently toying with his outer folds, the other wrapping around his spike, with just the barest amount of pressure when it came to tracing his biolights. Gratifying himself to fantasies of him and his lord laying together, in a delightful post-coital bliss, was something he would keep close to his chest, because it was so filthy, so secretive-
"M - my liege! You know..." he was wheezing, trying to look over his shoulder to face his lord, "I have always dreamt of this moment, every night it's kept me awake, just how badly I wanted this."
Megatron gasped softly, less in surprise at the statement itself, but with the details, and Shockwave gave a strangled cry as Megatron tipped over the edge and brought the tank with him. Sharp dentae were biting into his neck and he wailed as Megatron pumped him full of transfluid. His gestational forge spiraled open, and he could sense the draw into it, but it continued to fill him, until his forge was bulging out.
"Frag, Shockwave, do you know what that does to me? Knowing you've kept yourself busy on Cybertron, thinking of me?" The hand on his belly - so full of his leader's fluids - trailed down and gently grasped the tank's spike, thumbing the head. Shockwave whined, he didn't think he had a second overload in him, not in this state. But the touch burnt like a fire, and he began to breathe heavily.
"Megatron... please... I can't. It's too much..."
"One more overload my darling, for me. And then you can have all the transfluid your greedy, greedy forge desires. We'll kindle tonight, and if we don't, then we're going to try every single night until you return to Cybertron. You'll surely be kindled within that time."
Shockwave gasped, letting Megatron thumb over his spike and slowly pump the length with his hands. His antlers were twitching helplessly as he kept his helm thrown back in an exhausted pleasured haze.
"My liege, I would need to lie to them. Even moreso than I am already, nngh... perhaps that agent could be persuaded to spend some time with me, and I could convince everyone it was his." He moaned softly, as Megatron gently rubbed his groin, before going back to indulging his spike with attention.
"Very clever of you, though I expected no less from anyone half as talented as yourself."
"Flatterer." Shockwave snorted with the barest beginnings of laughter, only for Megatron to cut him off by thrusting, just once, and forcing the tank to overload.
Shockwave practically screamed, transfluid splattering his belly and his thighs, and the warlords' hand, pooling on the ground with the lubricant from their earlier foreplay. Megatron smiled, gently spreading his mate's thighs and continuing to thrust once Shockwave settled back down, though the poor scientist's breathing was still heavy and frantic.
"Better?"
"Yes, my liege... thank you."
"Tsk, this is about you, please, indulge."
Shockwave moaned breathlessly as Megatron kissed his neck, over the bite marks, and continued to thrust, both hands having moved now, to his waist, anchoring them together. The fact that Shockwave could feel his hands, but they weren't so close to where he was also used to his waist being meant he must have been so stretched out. Megatron's pace was somehow, even more brutal than it was before, but it felt divine, and he could vaguely hear the slosh of fluids in his forge, against the spike. He was starting to feel that post-coital haze he'd always longed for, but he knew he was to remain awake until Megatron was finished, so he let his mind wander, completely unoccupied with anything but complete and utter bliss.
Though it was likely longer, to him it felt like barely more than two klicks, Megatron was overloading again, pumping Shockwave full of transfluid, and this time, Shockwave tried to look back at his frame to see. His abdomen was stretching, the protoflesh achy and tender, and the warnings in his HUD were more visible than before. That, or he was paying more attention to them now, but he could see that they were warnings about frame structure, organ displacement, internal shifting, maximum capacity of his forge, but he dismissed them all. This was his one deepest desire, and he refused to squander it for something as insignificant as organ displacement. Though when Megatron pulled out, and stuck a short, thick plug into his valve to keep all the fluid inside he groaned.
"Shockwave, are you okay?" He could feel Megatron moving him, slowly and gently.
"Yes, why?"
The warlord had moved him so that Shockwave was leaning against the frame of his master, no longer on his knees, but resting comfortably against another frame. They were both still on the floor, however. "You seemed quite uncomfortable, was it too much?"
"No, I - the pressure is intense, but good. Very good, my liege."
"Tsk, my dear, tonight is about what makes you feel good. I am glad I fulfilled that goal."
Big, strong, gentle hands came to rest on the apex of his swollen belly and began to rub soothing circles. It was very fair to call it swollen, as it jutted out far enough to obscure the sight of half his pedes. And his pedes were not small. Megatron had him so full that he could feel the pressure of the transfluid that hadn't yet been absorbed or made it into his bloated forge pushing against the plug, and any small movement of his legs nearly dragged a strangled cry from his vocalizer.
"My leige, I came as quickly as I could!" Shockwave was panting, claws rubbing his belly.
How funny, he would have thought, that every time my lord and I meet, I am in such a state.
Though right now nothing was funny.
Megatron guided him to his quarters, and he locked the door from within, easing Shockwave onto the floor in a makeshift nest. It was made of parts gathered from the humans, bits of metal for framework, and soft warm fabrics to help ease Shockwave's discomfort.
"A - ahh my liege..."
"Easy, there's no need to speak too much, what should I do."
"The eggs... they'll need to be wiped clean, and then settle them here, next to me..." he paused, wincing as he felt the eggs shift lower, one lining up in the upper portion of his valve, waiting to be laid, "I - I'm so sorry, this was stupid of me..."
"Shockwave, my love, this was not stupid."
Shockwave whined and looked away, suddenly throwing his head back and practically wailing as the egg nudged forward into his channel. It hurt, there was no pleasure in laying, but conceiving them had felt so good. The eggs were huge, he was afraid they were going to tear him in two. Another egg was slowly shifting into place behind the first, and he tried to push, just like how he remembered. Just like how every Cybertronian had to when in labour, but it hurt, and he was so afraid.
Even through the haze of his vision he could see a hand, and he grabbed it in his own, squeezing it tightly, just as he pushed, and the first egg slipped free of him with a sickly squelch, coming to rest safely in the nest. As soon as the first was free, the second took its place in his channel and the pressure abated for as second, and then returned with a force. The hand tried to retreat, and he growled. The audacity.
"Shockwave, my love, I need both hands to wipe them down, my hand will return to you."
He groaned and managed a weak nod, allowing Megatron to wipe down their eggs, as he pushed in tune with the pressure in his valve. The second and third eggs slid free without much fanfare, and he could feel where Megatron set the first, before cleaning them both in order, and setting them next to their sibling.
However, the fourth egg was the last, and with nothing pressing on it to help start the process, he could simply feel it shifting contently in his forge, and he whined.
"Megatron... I - it won't come out."
"Here, let me help you up, I've looked into it, walking can ease you into it."
"Well, it was not easy getting here."
"I hardly doubt that." Megatron smiled, gently kissing Shockwave's neck and helping him to rise to his pedes, which he could see a bit more of. Shockwave wobbled on his pedes but managed a few steps on his own, a clawed hand gently cradling the remainder of his belly, where he could feel his last egg as it began to shift once more, this time, into a better position, right up at the top of his channel.
"Ah, it - it's shifting, you're right. H - help me back to the nest, would you?"
"Of course." Megatron took his arm and led his wobbly mate to the nest, helping him to lay back, and re-positioning the eggs to Shockwave's liking as the tank pushed.
The last egg slid free with the most fanfare, as it appeared to also have been the largest, and Shockwave threw his helm back and sighed. He was done, he was absolutely never going to have any more sparklings after this, it was just too much to deal with... well, at least until they won the war, then he could modify his frame to his liking and if he and Megatron so chose, they'd have however many sparklings they desired.
