My god I love your harem universe. Especially the Autobots and Decepticons having little piss fights over their precious human!

Now I’m just imagining poor Thundercracker and his “secret” crush on the human and how infatuated he is. Like a big love sick puppy

I can see him trying to shyly woo the human, possibly finding out where the human lives (from Skywarp cuz he couldn’t keep his mouth shut from his trine), sneaking over at night when they’re sleeping and doing something cheesy like throwing pebbles (small rocks) at their window to get their attention.

Poor guy probably fumbles and is blushing and he would just be so darn cute trying to ask the human out!!

I love thundercracker so much, thank you for this.

Thundercracker knew he shouldn't be here, he knew it well too, if the autobots won't have his head then the other decepticons would, the very thought should stop him in his tracks.

But here he stands just outside your habsuite, he's not sure what humans call it, but it looks nice, and is further away from town so he won't run into more humans, just you. Just you is all he wants, yes he's seen the footage Laserbeak caught, yes he watched it over and over and over again, imagining him as your lover.

Yet his spark yearned for something more.

You seemed so sweet, so funny, so considerate, that maybe, just maybe he'd have a chance with you, you already have s bunch of lovers, what's one more, right? He couldn't face you, but what could he give to make you know he wanted you?

Each morning when you'd awake, ready to head back to the autobot base, there would be quite the gift waiting for you.

First it was a big thing of energon, something you couldn't drink, though you've tried.

Next it was a massive geo cluster that had you in awe, you could barely manage to get it into your house, it was half the size of you! Next were some large sunflowers, root, dirt, and all on your porch.

A part of you wondered if you should ask around base, but maybe that would ruin the surprise? Or maybe it'll get them paranoid that someone else wants you, you don't feel threatened so you don't mention it.

It's not every night, but it's every other weekend, so it makes you wonder what their schedule is like.

Thundercracker can't believe himslef, he's like a sparkling all over again! When had his spark last pumped like this? The nervousness that ate away at his confidence, his anxiety rising each time he snuck away from the ship, and landed a little ways away from your habsuite, just as he's done every other weekend.

Walking as quietly as he could, making sure the groun beneath him crunched very little, he made his way up your driveway, ready to place yet another gift of flowers at your doorstep. His red optics look around, stopping when he saw the other flowers he gave you planted in your front yard.

You liked them! His wings twitch behind him, fluttering happily, he can't stop the smile forming on his face plate.

He looks at the very delicate flowers in his servos, the plants nearly as tall as the last bunch he gave you, but in reds, purples, and pinks, maybe you'd like the variety more? He hopes, he can already feel his spark racing.

Thundercracker carefully lays the flowers on your porch, making sure they are neat and out of the way so you won't step on them. He leans back eyeing his work, pleased with himself.

Your planet has many weird resources, but he's happy to have found something you liked! Normally on cybertron he would've found and gifted you shiny metals, or maybe even rare ones.

He wonders for a moment if you'd like an aerial show, and let him show off for you? Nah, that's too much, at least for right now-

"So you're the one leaving gifts for me."

You have to bite back a laugh as the giant bot jumps, flinching at the sound of your voice. His optics wide and staring at you like a deer caught in headlights. There you stand on your roof, in your sleep wear, with a tired smile.

Thundercracker tries to control himself, but little does he know he wings are giving him away, shaking as he calms himself.

"Oh..I..uhh..I didn't mean to wake ya?"

His face plate is heating up, flushing a deep blue from the energon going to his helm.

"You didn't wake me up, I was staying up in hopes to catch you. I was wondering who was leaving me these things."

Oh Primus, he made you miss a rest cycle? Frag, he feels so bad.

"Thank you."

.....huh?

You smile once more, chuckling at his baffled expression.

"Thank you for the gifts, it's very sweet of you, Thundercracker."

You wish you could take a picture with his stiff his body gets, how his wings wiggle up and down, and just how adorable such a normally intimating con could be.

You knew his name, you remembered him! That means you think of him, right? He could melt right where he stood, he could offline right now and die happy.

"Don't mention it." He carefully sits down on yout lawn, allowing his face to be more level with yours, "On Cybertron it was common practice, mostly for us seekers, to gift items like this."

"To start a courtship, I take it?"

You can't hold back laughing now, nearly wheezing at how he sputters and trips over his words trying to explain no but yes, but also-

"How did you-"

"Wild guess, but your reaction was too cute."

He's going to die, this is how it ends for him, the cute human he's taken with flirting with him.

"I wouldn't mind."

Truly you wouldn't, you know your agreement with the autobots, they all agreed to be your lovers and not fight over who else you date, but you'll have to have a talk with them about at least Thundercracker.

He seems so sweet under that gruff exterior.

Even if such a big scary con shakes under getting a few compliments.

Thundercracker rut cycle

Thundercracker x human

Rut cycle masterlist

Word count: 1.9k

Warnings: NSFW, Smut, giant/tiny, praising, sub Thundercracker.

This mech needs so much more with smut fics but gods did I have fun writing him getting treated to some praising.

_______________

The little human from earlier had Thundercracker's full attention. They are peacefully unaware of his burning gaze on them despite the sweet scent that came from their smaller frame, making him nearly snarl with want. His vents hitch slightly each time they shoot him a slight glance.

Venting deeply, the Seeker steadied himself. Fighting a losing battle to purge heated lines each time his frame caught a whiff of their scent, it was truly maddening to him, most times during rut he had Starscream or Skywarp, but as of recently neither of them had the time nor the interest.

"Hello, can I help you?" They call out to him their voice sounds so sinfully sweet to him that his digits dig into his servos as he watches them. They weren't afraid like many others of their species. Thundercracker vented sharply as the sweet scent of the little organic's arousal hit his olfactory sensors. His valve clenched and spike throbbed behind its panels at the alluring smell.

He reigns himself in enough to talk. Leaning down, his optics roved hungrily over the small creature's form. "Hello, fleshling," he rumbled, fans whirring loudly. The seeker cycled several intakes, struggling to override protocols screaming for him to claim a mate, he knew he should go and find one of his Trine or just another Decepticon but he was getting sick of getting sidelined over his needs.

"Your scent, it's very intoxicating" Thundercracker said gruffly. His plating felt too constricting against his frame, everything was screaming at his processor he needed to interface. The seeker loomed closer. They continue to watch him warily but relax slightly. "Oh, um thank you?" They feel rather exacerbated by the strange comment from the cybertronian. Their eyes flick to his vents that cast out loud whines with air as his plating shifts uncomfortably.

"Your species bears no reproductive cycles?" He questions helm tilted, most times all it took was remarking about their scent for Thundercracker to get someone in a berth during his rut, but now he's starting to question if humans actually have cycles. His panelling felt molten.

"Oh no, humans do have a reproductive cycle, we just don't tend to um.. smell it. Sorry you just took me off guard, I was aware that the Ark was on somewhat of a lock down due to your people experiencing some problems" They fluster slightly over saying it.

Leaning closer, the Seeker met their gaze. gritting his denta, as he tries to figure out the best way to broach the subject. "Are you alright, do you need me to get someone?" They ask softly. Thundercracker vented sharply as another wave of their scent washed over him. "Fraggit," he growled, fans whirring into their highest setting.

"I...apologise for my lack of control, it's getting to me. And no I doubt the other would be interested in helping" he vented. They look around for a moment, going quiet. "Close the door and sit down, you have to stay quiet though" they instruct while quickly making sure that they are the only ones in the room. "Do you want help with your problem?" They ask while motioning to his now leaking interface panel.

Thundercracker cycled a heavy ventilation as a whine leaves him, wings flicking at their words. "Primus, yes," the seeker growled, fans whirring loudly. He pressed the button for the door to close with a click, then lowered himself to sit on the floor. His optics burned hungrily as they roved over the human's smaller form.

The seeker cycled several intakes, fans howling as another surge of the organic's scent rolled over sensors. The moment they climb up onto his lap it has the seekers servos wrapping around their waist pulling them flush against his panel.

"Easy big guy, don't want you breaking me" they chuckle trying to make light of the situation. "Gotta be gentle with me, I'm human remember, I'm happy to help but you have to be gentle, tell me what you want pretty mech" they coo softly at him. Running their hands up his plating teasingly. Thundercracker managed to chuckle, though his voice carried a husky edge, betraying his own need.

"Alright, alright, I'll be gentle," he replied, his words laced with a mix of desire and restraint. He knew the importance of control, especially with a fragile being like this one.

They gasp as his servos cup their hips, feeling the way the metal digs into them through their clothing, They look up at him. " Is this alright?" They ask while slowly grinding against him.

The feeling has him nearly moaning as they grind against him. "Yeah, it's... it's more than alright," Thundercracker managed to reply, As they continued their slow, deliberate grinding, Thundercracker felt himself teetering on the edge of restraint. The sensation of their body moving against him, the heat and friction building between them, has groans and heavy vents of air falling from him.

Transfluid slowly leaks from the seams of his interface panel, as he continues to grind them against his heated plating. They gasp when the pink fluid begins to stick to their skin. "Didn't take you as one who liked humans" they chuckle softly,getting more comfortable as they continue to move against him.

"Oh, you have no idea," Thundercracker replied, his voice tinged with a hint of amusement. The pink fluid that now adorned the human's skin and clothing has an almost primal part of the mech wanting to just rip the fabric off them. As he continued to guide them in their movements, the sensation of their bodies moving together sent shivers of pleasure through him. "You humans have your ways of surprising me," Thundercracker remarked, a playful smirk playing on his lips.

"You seem to be handling yourself rather well for being in rut" they tease, playful touches continued to stoke the fire of his arousal. "Well, what can I say? I've had plenty of practice," Thundercracker replied, despite the overwhelming sensations coursing through him, Thundercracker found himself oddly at ease in the human's presence, much more than he would be with Skywarp or Starscream. He didn't feel like he had to put up the Decepticon facade.

"Don't get many chances for release?" They inquire, as Thundercracker begins to trace their body through their shirt, enjoying how soft and delicate they feel. "Though the Decepticons would want their troops in tip top shape " they discard their shirt for him to have more access to their skin.

"Release? Ha! You have no idea," Thundercracker grunted, his voice tinged with a mix of frustration and desire. "Peak condition? Yeah, right," Thundercracker scoffed, his movements growing more urgent as he touched their chest and stomach caressing and admiring. "The Decepticons don't care about our well-being, just our obedience," Thundercracker remarked, his tone laced with bitterness.

"Why do you stay with them then?" They hum as the cool metal of his servos trace down their chest and stomach, a deep hungry growl leaves him as the hormones and pheromones from their body make his own arousal more visible. "Why did I stay with them? It's complicated," Thundercracker began, his voice tinged with a hint of hesitation. The memories of his loyalty to the Decepticons, despite their lack of care for his well-being.

"Starscream and Skywarp are why I stay, they are my trinemates" Thundercracker explained, his movements growing more urgent.They move back enough to pull their pants off, throwing them to the floor and moving back to sit spread across his lap. "Come on pretty mech let me see what you've got hidden here, ill take care of you" Their bold actions sent a surge of desire coursing through Thundercracker's circuits, his systems humming with anticipation as they straddled his lap.

With a deep growl of longing, Thundercracker's interface panel opens his spike surge forth, transfluid leaking from it and down into his lap. "Oh woah" they stutter looking over the details and colours of his spike, the pink transfluid leaking through the ridges of his spike. they run their hands along it while moving closer for Thundercracker to grind against them. "I don't know if that will fit " the state shyly

"I assure you, it will fit just fine," he reassured them, his words carrying a hint of mischief and desire. As he lifts them up, slowly letting them get comfortable as he slowly presses into them. A loud moaned whine leaves them as Thundercracker presses his spike into their tight sex, his servos holding their hips as he grinds his spike deeper.

It is a tight grip and sinful feeling of how tight a human is wrapped around his spike. "Mmm, fuck never thought I'd be fucking a Cybertronian" they mumble thought a shaky breath. Gasping loudly as he thrust and rocks against them, never too rough with his movements.

As he grounds his spike deeper, feeling their body react to the tight grip, Thundercracker couldn't help but let out a low growl of satisfaction. "Mmm, that's it," Thundercracker's voice is a husky whisper, filled with desire. "You feel so good wrapped around me, human. Never thought I'd be indulging in such pleasures with one of your kind," he murmured, his tone laced with a newfound appreciation for the human before him. Despite the general disdain that Decepticons held towards humans and organics, he is rather enjoying himself.

Thundercracker found himself lost in the intoxicating sensations picking up his pace as he leaned back on the floor, wings twitching and stretching each time he tilted in them. feeling their tightness compared to Skywarp and Starscream, Thundercracker couldn't help but be amazed by how different it was, they are so much warmer and softer than a Cybertronian but took just as much of his spike.

"Mmm, you're something else," Thundercracker's voice was filled with admiration and lust. "You take me so well, frag im close," he confessed, his optics flicking off as he begins to buck into them. Their fingers scratch at his plating as Thundercracker growls lowly. He is so close to overloading despite not wanting to, his frame is pent up and this sweet little fleshling has him nearly a puddle on the floor due to how soft they are.

A primal moan escapes his vocalizer as he overloaded, grinding deeper into them as he holds them flush against his frame rutting into them trying to make sure they take as much of his transfluid as possible, little praises leave him as he holds them close. Loud moans leave them as they grip onto his plating as the bright pink fluid begins gushing from them, leaking into Thundercracker's plating and onto the floor. “ fuck..” they whine as they press their forhead to his frame.

“Are you alright?, your not hurt?” Thundercracker begins only for them to press back down onto his spike earning a mix of legitimate mix of words. “I'm more than alright blue but it looks like you need a lot more than just one go” they tease. Feeling how pent up he still is. He goes to move only for them to press a hand to his middle section. “Ah, ah no, I'm not done yet, pretty boy, you and I have some more getting to know each other to do” they coo at him onyk for his thrusters to flick on from their words.

Thundercracker could get used to this, he realises.
