Introducing, the Box AU @lets-try-some-writing and I have been co-developing, where it turns out that changing your body to blend in on an alien planet can have unexpected consequences
"Hasbro would never allow for MegaOp to be canon so I'm about to pull the funniest shit in Transformers history" -James Roberts writing Megatron and Ultra Magnus
something that was chewing on my head for a while... the sex appeal of Tarantulas. first time writing something like this so... uh... might not be so good. did not have any particular versions of him in mind, i was contemplating between beast wars and IDW so here's a ambigious smutshot that would work for both. but i'll be honest, his IDW design fine as fuck brah Prowl fumbled.
scenario: you're beast modes seem to have significantly altered your systems... and have added some additional functionalities, Tarantulas is thrilled to explore them with you.
warnings: filth. teasing. ovipositors. egg laying. freakish biologies. tarantulas is a FREAK. unhinged even? kinda half assed. TALLER READER.

Tarantulas has an... itch. Now, he's typically able to control himself well. He's never had an issue with that in his existence. However... this beat mode is really, really getting to him.
You were in his lab like usual. Minding your own business for the most part, he thinks of you as his... "partner", oddly enough— He's never really considered anyone to such a high degree before, most "partners" were dealt with once he got what he wanted out of them. Or they betrayed him.
But you, you're special. To him. Its not like you have any sort of scientific temperament he might've found useful but you know how to keep a secret and he values that. Besides, you're a partner to him. Who else would he want to explore this with? The more... animalistic sides all of you seemed to inherit from takes these new alt modes had their own impulses packaged with it. It was strange, carnal needs were not something your kind typically faced.
But it was different now. A hot need swept to his frame and naturally, he turned to you.
So here you are, splayed out before him after a gruelling... who knows how long session of being teased. Despite how he's attempting to drive you insane, there's clearly something off about him. You can tell. He's... gentler? Less cruel. Its unlike him. His touch, although heated and feverish, has a kindness to it.
A relieved moan leaves your vocalizer as you feel his heavy spike slide into your valve, your face burying into the work bench your bent over--- You're probably going to have to help clean this up but you can't even begin to even think about it. Though, he does feel... heavier than he would normally. Nothing your bigger frame can't handle. His pace starts off slow, teasing. Once again.
"Come on.." You've waited patiently for long enough now, Tarantulas laughs a bit, venting hard. You're starting to consider pinning him down and just-
"I suppose you do deserve better..." That... throws you off. No begging? No sadistic humiliation? No degradation? What.. What is wrong with him?
"Tarantulas, are you... h-hah... are you okay?" Your servo holds onto the nearest surface you can find tightly, digits digging in. His pace gradually quickening. You tend never prod into these sort of things, he's quite reserved when it comes to how he feels and such..
"I'm perfectly f-fine.." He says, vocalizer sputtering as he feels your walls clench down on him, a soft moan leaving your dermas. "Am I not supposed to.. nnghh.. reward you?" He says, going quicker, harder. you can tell he's almost there and so are you. Its getting progressively harder to think of replies, frag, to even think in the first place after being teased for so long. Helpless under him.
"Consider this a gift." He says, his tone was off. As if he were expecting something. He continues, speeding up slightly, going rougher. His spike hitting all the right spots, he's mapped out your frame now.
You're not sure what is going on but you feel... something solid. Something piercing through the entrance to your forge and a surprised moan follows, your temperature doubles— The heat from your vents starting to precipitate on your frame, the intrusion sends a warning to your HUD. Something... Something just went through. Your optics shot wide open and another strangled moan left you. It hurt. But why did it feel so good? It stung in a strange way, a strange pleasurable way. The amount of web-like pink transfluid he's coated your insides with was more than enough lubricant for this... what felt like a gelatinous mass to slide through. You're struggling against his grip but Tarantulas is determined to keep you here like this. Your back struts arch as you feel another one pass through, resting in your tank. Tarantulas practically revels in the sight.
"Fascinating.." He pants out, his servo moving to your abdomen— A heat present within, not of your natural frame but as a reaction.
"What.. What is that!?" You manage to vocalize, stabilizers shaking, almost giving out on yourself. Your servos desperately grasping for some support to calm yourself down, your actions are not surprising such as intimate area is usually left untouched... nothing is typically supposed to go up there.
"Oh, don't you worry." Tarantulas groans, his helm on the back on your neck supports. Inhaling your scent. His free servo working up your spike, the tip of his thumb rubbing gently around the duct had you mewling.
"Its-Its going inside me!" It was supposed to come out as a shriek when you felt yet another one slide up, his spike twitching & pulsing to get whatever it is inside you. His servo working harder on your spike, trying to distract you and it works. He's got you moaning out loud.
"And I'm already inside you." He's being cheeky, there's a playfulness to his raspy voice as he reaffirms his grip onto your hip struts, tightening it to make sure he's at the hilt of your channel. His servos going up and down your spike at a quicker pace, the attack of pleasure from both sides leaving you utterly weak to him.
"N-Not like that!" You whine out, trying your hardest to ensure that your stabilizers don't give out on you at this moment with him behind you as another he continues to give you his eggs. Despite the lack of a traditional intake, you can tell he would've had a cheeky grin.
"I meant... the.. haaah... wh-whatever is going up my tank!" Its hard to articulate with how overwhelming the experience is, the stretch, his attentiveness to your spike, the fullness of your valve... His servo continues to work up your spike and the way your optics roll back when your splattered your own transfluid over your chassis was to kill for in his opinion. You spike twitches in his servo as you overload nears.
"Ah.. yes, th-that..." He murmurs, raspy as your valve clenches down on him with the way you bulldoze yourself through another overload, a loud moan leaving your vocalizer. "You needn't worry yourself with s-something... as trivial as being an incubator." He buries him helm into the back of your neck, it takes a bit for his words to really register and you get what he meant with how hazy your mind was, still on a high. You pant, taking a moment to regain your bearings & get the heat out of your overworked systems-
But then it clicked.
Holy frag.
He's laying eggs in you.
Your optics are wide and you try to look back at a pleasure-drunk Tarantulas, slightly difficult from your position but you catch a glimpse. What the frag? He can lay eggs??? How??? Was it by the virtue of your alt modes?? Would you end up being a parent!??! What is he thinking??? WOULD IT HATCH IN YOU?
"Oh, don't look like that~" He teases, seeing your horrified expression. "These are just... some quirks we've gotten with our new alt modes, dear." He chuckles. "And there's no one else I'd want to test these features on than you."
"You're... You're horrible..." You pant out. Of course he'd use you as a test subject... He could've warned you at least when he brought you here for your usual activities.
"I doubt any of these... eggs would harbour actual life of any kind. Us Cybertronians are n-mmFF..." He feels your valve clench down on him even tighter with the rhythmic pulses of his ovipositor, the ridges striking against nodes as his eggs find their way into your tanks. Your claws are practically digging into this wall of the laboratory, processor dizzy with all this pleasure.
"Nhnn... Tarantulas..." You whine, feeling his eggs enter your forge one by one, taking its place within your tank. The gelatinous substance rests inside of you, steadily. Your optics look down to see where your frame feels heavy from the sheer amount he's planting into you. There's steam fuming from your vents, this whole thing is making you so, so dizzy.
Its... hot. In a weird, freakish way. You find yourself into this in spite of everything.
"Mm.. How delectable." He groans out, his voice slightly shaking. Primus, if you could see yourself through his visor... Full of his eggs & spike. He's made sure that there's not a single tank he hasn't filled of yours with his transfluids. His grip is shaky and one servo moves to your lower abdomen.
"I-I can't-" Another plea from your side, you can feel his helm by the side of yours as his spike remains firmly pressed against end of your channel. A small line of drool from the corner of your intake, positively spike drunk. This feels unlike anything you've ever felt. The constant pulsing of his spike striking against nodes in a rhythm, you might just overload on his spike while he's doing this.
"Nonsense." He hisses out, groaning. Tarantulas needs this. Badly. His servos are quite literally denting your hip struts, holding you tight. His mandibles grazing against the back of your neck supports as you remain panting.
He grabs you by your hip struts and sits down with you on his lap as you remain full of him, vents blaring out the heat from your systems. You're so warm... Tarantulus isn't sure if he'd ever want to pull out. Your insides are so warm... And you look so cute like this! Full of his eggs, you're drooling too. The small distention at your abdomen, he practically coos as his servo caresses the area. You involuntarily flinch, clearly not used to having your plating do that. Your optics remain wide as you try to process what just happened, the overwhelming pleasure wearing off.
But you... you want more. You like this feeling, its alien in every way possible but this is unlike anything.. and everything you could ever feel. You have no idea why you even want more, it feels like... instinct.
"Again. Please? J-Just... Once more?" You're pleading him so sweetly and Tarantulas would, he would all the time if he could. But it throws him off. He'd have guessed you're tired, or maybe even cuss him out without giving so much as a warning.
"I'd love to but I need a moment..." His servo gently presses against your distended plating and he gets your whimper as a response, he's surprised you want to go at it— He would've guessed something like this would feel at least uncomfortable given this isn't how Cybertronians typically... interface. But its a welcome surprise, that 'itch' in his systems feel relieved when those eggs made their way out of him.
"I can take more..." You whine and you feel his spike twitching at that. You're so good for him. You gently rub your stabilizers together just to tease him, his spike still inside you.
"How o-obscene!" He cackles, not expecting that. Sputtering a bit even. But if its more eggs you want then... he might as well fill you to the maximum.
"You like it when I'm like that.." You mumble out, kissing his face mindlessly as you remain with him deep inside you. The deepest anyone has ever gone....
And how could he resist you? Half lidded optics looking at him begging to be full, the vents working overtime on your frame and don't even get him started on your valve. He shudders, primal coding going haywire within him. Considering you're from a larger size bracket, you probably could take more and that... that entices him.
It's going to be a long, long night.
BONUS: graphic egg laying. like next level freak stuff.
"Shhh... Sh... we need to get them out." He has you on his lap, the gelatinous blobs have hardened slightly. They have been incubated enough within you. Tarantulas now believes its time to help you take them out. Poor you, walking around base so heavy, carrying his fluids and eggs. And the best part? Your mid-section plating seems to have distended a bit more than when the eggs were first left to incubate. They must have expanded a bit more within you, the covering must've gotten harder.... The sight was painfully arousing knowing that it was he who was responsible. Thinking about the changes that are happening within your frame only serves to excite him more. None of the others knew a thing but at this point, Tarantulas doubts he would care if they knew.
He would've grinned if he could, Tarantulas' digit gently makes its wave into your valve, going deeper than he usually does with his digits. He pressed down on a something and a sudden, sweltering heat hits you in your core, all the way down to your array. All your equipment coming online as your biolights pulse with a strong intensity. And you feel fluid... gush out of your forge... The seal overriding. You're squirming in his grip as his lap is stained with his own fluid, moaning as you feel his digits rhythmically hit that spot.
"Oh, calm down.." He mutters, slightly amused by your show. The other servo wrapped around you tight, gently stroking the distended area. You can feel the eggs start to slowly slide down. Its an odd feeling... His digits pull out of your transfluid soaked valve glistening and moves to your cute little node instead, his thumb gently rubbing the node, massaging it— He knows you'll need a lot more lubricant to get them out of you and what better lubricant than the one you can naturally produce.
Your moans follow quickly and you feel the first one slide out, its... harder and bigger than it was when placed inside you. You whimper, pushing your hardest as the spider continues to tease your node.
"Tarantulas..." It comes out so needy, so desperate, so... unlike anything he's ever heard & the way you're looking at him.. Are you asking to have more eggs in you? Because he could & would if you kept acting so-
Tarantulas is snapped out of his thoughts when he sees one of them, slowly coming out of you, stretching you valve open. Cursing under your vents as your stabilizers shake. The egg is slimy and moist as Tarantulas watches keenly, no longer hitting you with a witty quip.
The mad scientist finds this obscenely arousing. Oh Primus, he's just going to have to stuff you with eggs more often now, won't he? Primus knows how many he's managed to place in you. Though, he doubts you'd be happy to know that.
"Nnghh..." You whimper as Tarantulas gently pulls it out of your valve with a wet, pop sound. Another wet, slimy egg sliding its way out.
"H-How many are there...?" You mutter, the discomfort was... something and pushing the eggs out was not easy, your poor gaping valve ruined.
"A lot more. You wanted to be full yesterday." Tarantulas breaks his silence, recalling the night before. You whine when you hear that, there is a subtle embarrassment flashing across your features. This is going to take a long while. You have an expression he could only call a pout across your face, he cackles.
"If you don't take them out now, they'll harden significantly and this process will be a lot more painful." He explains, his digit drawing a circle around your abdomen and your blinking node, making your channel even wetter, back curving slightly against his frame as you try your hardest to push out the remaining.
"Besides, what if they hatch within you? We wouldn't want that..." His tone goes low in a way which concerns you.
Oh, how he wishes you didn't have to take them out... He wanted you to walk around like this so so badly. So full, so needy for him & so willing. It was almost like a primal need.
Your face, despite the fact that its metal becomes pale and panicked.
"I THOUGHT YOU S-SAID THAT WASN'T POSSIBLE!!!" Awww, your optics are all wide... Tarantulas enjoys messing with you, maybe a little too much. Your servos holding onto his arms even tighter.
"You never know." Despite the lack of a traditional intake, you can very well see the smile on his face.
Maybe next time, he should have you trapped in one of his webs before having fun.
@bean-with-a-knife and mystery info anon the goat. ik this isn't accurate as to how spiders use their equipment but i deadass got a bit too horny also HOLY SHIT YOU GUYS REALLY WANT HIM.
whoever you are, know that you are the goat.
i HC that tarantulas has pink transfluid and it kinda shoots out like webs... mmmm
Loving the Structibugs! Do you think that they'll keep sneaking in because they see Prowl being maternal towards Bluestreak and slightly bigger than them, and think, "Hm, what a perfect Queen!" Looked up termite facts, and apparently, the King and Queen rule together and mate for life as the king fertilizes the eggs, so Scrapper could be King as the boss unless the Structies all share it. It would be perfect to match and explain the 2 sets of Triplets! They keep sneaking in to steal Prowl away to their nest, and Jazz keeps having to rescue him. Hm, what if they see Jazz as a possible king?
i think that cybugs have their own societal structures (e.g. seekers and whatever is going on with trines) but that's very fun to think about shfjfhdk,, they aren't Truly a 1-1 comparison with any real life species (praxians have also been compared to bees in the past i think. if not ive been thinking about that too lol)
ive been thinking of the structibugs as more like. a miniature colony of their own or a smaller group that intended to split off to make their own colony... scrapper is still very much the leader, and if anything, they see j+p (&b) as the leaders of a neighbouring colony/group of bugs.
also while im a constructiprowl enjoyer, thats pppprobably not in the cards for this au? however. saying that... i also think itd be funny if prowl just. keeps accidentally wooing other bugs without intending to.
(im assuming by two sets of triplets you're referring to the constructicons... ? personally i tend to lean towards the structies being unrelated "biologically" but i also think them being brothers is very fun! im curious as to which of them u think of as triplets :0...)
