Insceticon Bumblebee shenanigans

One day out of the blue Bumblebee was surrounded by eggs in a fairly comfortable nest. Poor Optimus is both confused and some what impressed that Bee was able to keep his carriage a secret as a whole.

So while everyone is gossiping about the possible sire or sires to all the eggs. Meanwhile Bumblebee is happily content tending to his nest purring away as he keeps his eggs safe and warm.

Bee 100% thought the seeds were duds only surprise surprise, Starscream has never laid a dud seed in just life.

[the-sheep]

Just curious, what was skyfire’s reaction when Starscream told him that he was carrying?

Skyfire actually told STAR that he's carrying.

and then they simultaneously remembered every complication that prevented them from doing it on purpose years beforehand. and had two very different flavors of panic attack.

[yayasvalveplay]

Imagine a scenario in which Starscream gets redeemed (thanks to Jetfire's efforts) and sides with the Autobots. But the funny thing is that they are actually a couple and have to hide it until the war is over. They're really good at it. They're so good that at one point someone asks Starscream, "Hey! Did you know that Jetfire became a father? He has such a wonderful sparkling, I would kiss the hands of the carrier who brought it to life! ," and Starscream, without looking up from reading, silently stretches out his hand to the speaker.

The fact that no one knew starscream was pregnant after the war is very funny to me. Like you would if thinked both of them would be bragging about it (mostly Star) but they'd been hiding their relationship for so long, they forgot to go public.

And him lifting up his servo to the bot who asked about kissing the carriers servo is even funnier.

There's a pause because the bot doesn't know what to do.

Starscream: "Well?"

Bot: " Well what?"

Starscream: " Go on. Kiss it like you said you wanted to do."

Shockwave goes into a sort of breeding frenzy and fucks a brood into Soundwave's forge (they're just role-playing its okay) (Soundwave will not walk after this)

>:D

Very supportive of this

TFA MegOplita makes very little sense but that ain't gonna stop me from thinking Blackarachnia would look very good sandwiched between Optimus and Megatron (the former spiking her, the latter getting spiked by her), and TFA Shocklita makes no sense whatsoever but that ain't gonna stop me from thinking Blackarachnia should kick Shockwave's aft and then lay eggs in him.

[cozzzynook]

A little NSFW bonus for the TFA Au ;)

Optimus felt like his whole frame was burning with how much charge ran in his lines. It also didn't help that he was currently wearing some frilly fabrics that Megatron requested. "Are you really sure you want me in this? I don't think it matches with my colors very well"

"Nonsense my dear~" Megatron purred using his free servo to gently lift Optimus into his lap. "You look stunning"

"Well, if you like it maybe its not so bad" The prime pouted as he slowly begin to run his servos along the broad grey chest.

A deep rumble escaped Megatron's engine as he relaxed into the light touches. His large servo drifted lower until one digit brushed along the prime's aft and panels. He began to slowly rub circles on the closed panels while his lips quickly got to work kissing and licking away at those cute finials.

Optimus moaned leaning back against the digit chasing after the friction. Charge slowly began to pool in his tanks making his valve clamp down on nothing as his optics drifted towards Megatron's own panels. Oh how much he wanted to ride that thick spike until his hip joints gave out, with needy servos he removed them from the grey chest and began to paw at the panels seems with a whine.

"Greedy little thing aren't we?" Megatron teased placing a light bite onto a finial. With a hiss he retracted his panel allowing his spike to pressurise, its slit already leaking with pre-fluid.

Swallowing thickly Optimus could hardly contain his excitement as he reached out to grab the spike. His servos barely touch as he leaned in closer to place his own kisses on licks. The tangy flavour of pre-fluid on his glossa sent a thrill down his spinel strut urging him to keep licking and sucking at the tip. He hadn't realised his own panels had opened until one large digit slowly ran against his wet folds drawing out another low moan.

"Mmm more~" Optimus panted his blue optics dark and heavy with lust.

"What's the magic word?" Megatron wrapped his servos around the prime's hips and waist just lightly stroking the seems and wires.

"Please"

With a smirk Megatron lifted Optimus up guiding him until the entrance of the valve sat just above the spike. Slowly and carefully he lowered Optimus onto his spike, his optics focused on the mechs face for any pain or discomfort until he was far as he could go. The warlord would place small kisses on top of the prime's helm as allowed Optimus's valve adjust. "You alright love?"

"Yeah" Optimus nodded a flirty smile on his lips. "Come on big mech, you want an heir right? Then frag me until I'm full of your transfluid~"

A growl escaped the grey mech's intake as he tightened his grip around those waist. His thrusts started slow but long ever being so careful as not to break his precious love. Now if Optimus was a warframe, he was sure they would be fragging like feral mechs in heat. With another low growl he clamped his teeth over those sensitive wires in the prime's neck drawing out a keen from the smaller mech.

All Optimus could do was tightly brace himself as his whole frame shook with each thrust. Each node cluster was struck over and over building charge quickly making his plating buzz, his cooling fans whirled loudly doing their best to cool his rapidly heating frame. His valve greedily squeezed and fluttered around the thick spike already trying to draw it deeper and deeper. "Oh frag! Mm- more I getting close!"

Megatron sped up his thrust until the head of the spike pushed against the entrance of the gestation chamber. He would support Optimus weight by bracing one servo against the primes back and with one very slow and deep thrust his spike slipped inside. A cry escaped Optimus as he threw his helm back in overload, his valve squeezing while his frame shook making his cooling fan whirl. The sight was beautiful and was the push he needed until he too overloaded with a deep groan, his spike throbbed as it flooded the chamber with thick transfluid.

As exhaustion slowly kicked in Optimus watched how his tanks slowly swelled both full and heavy with precious fluid. With a content sigh he rested his helm on his lovers chest, happily listing to the gentle hum of Megatron's spark. He didn't fight the call of recharge simply shutting his optics letting those large servos take care of him.

"Sleep well my love" Megatron whispered before placing one last kiss onto the helm.

Thank you tfa anon! I love this story!

I just know their bitty is super cute and megs can’t wait to spark him up again..Optimus pretends to fuss hut he loves it 👀 hehe

Now..i wonder if angst will come or be revealed about his past & his mysterious sparkling? 👀

[brawnsleloenigmadoublesonic]

*sees you reblogged that mychlapci post with chubby pregnant Optimus* Oh 👀👀 you're also a person with refined taste? Petition to make Oppy a sexy plump milf that's always shocked to find out he's pregnant because his cute chub is always hiding the baby bump until the last hour.

Absolutely!! He's so chunky and squishy, how could you notice the bitty? They always stay undetected until he's already pushing them out... He's used to it, at this point.

[valvehuffer]

yknow, I don't think that Cybertronians can really get pregnant.

of course, in a valveplug setting, then yes, absolutely, it's hot.

however, in canon material? depending on the iteration, I think it all has to do with the sparks. Two bots pressing their sparks together, and one of them (or both) will end up with a little spark forming in their own spark chamber.

after it gets big enough, it gets put into a frame the two creators made. (I think it'd be cute if both creators put a piece of their own armor or protoform to help make it)

and then boom! newspark!

but mechpreg is absolutely fantastic in valveplug scenarios

[radio-wavelengths2]

Imagine if Longarm, after seeing Bee for the first time since he disappeared on Earth, decides to baby trap him.

Like, he doesn't want to be away from his little Sweetbee anymore, so he gets Bee to spark him up so Ultra Magnus would let him stay on Earth

BABYTRAPS HIM BDHSHAHHAHA

Obviously the Autobots need new soldiers, and if a mech sparks another up then it's his duty to stay and take care of his partner! So, if Longarm gets sparked up by Bee, it would make sense for him and Bee to stay together!

He needs to be able to be around him all the time! Always able to ride his spike and let Bee kiss and hold his swollen belly whenever he wants 🙏

[starscream-is-my-wife]

Real messy sketch but although I like to joke about Megatrons seeker fetish, he’s like, the ideal female bird, seekers probably love him too

Muted colors to blend into the environment easier, larger to sit in a nest (female birds of prey are like, 30% larger then the males), tanky to protect the nest, has great thighs

Long legs

Sorry for posting about breedable megatron again I recently rediscovered me being in denial about myself 4 years ago and my friends being right

[yayasvalveplay]

I know Optimus is submissive and breedable, but when it comes to TFA all I can think of are those beetles where the males are just normal looking guys while the females are huge and monstrous in comparison. Like Optimus sees Megatron and immediately pops the hardest boner of his entire life.

Megatron being the equivalent of the hottest female beetle is so funny to me.

But he'd work it, being all sly, getting into Ops panels so he can get sparked. Op doesn't realize what's happening until it's too late, and now he has sire duties. But on the plus side, he has a hot scary wife.

Maybe if he's good enough he'll be breed once their first batch are born.

Mer formers dratchet finding a sparked Rodimus who was abducted from his home and can’t go back because it was destroyed?

Now they have a sparked distrusting & traumatized mer they are slowly falling in love with

oh yes

The way this idea just gripped ahold of me and I love this idea but got a little caught up in plot and it got pretty long.

I've got another related ask, too. It's probably a bit less horny than intended, but I'll do more in a bit. Happy mermay!

Rodimus grew up in the Nyon shoal and was very social and comfortable and happy. Their shoal was settled around an uninhabited island from which they took their name which spent most of the time submerged and has complex reef system around it. It was considered one of the most beautiful places on Cybertron with pink sands and fiery colors mers matching the reefs surrounding it. It was Preserved and people weren't supposed to travel there but that didn't stop an occasional wealthy mech from hiring someone to go there as they considered fees to be "entrance payments" more than punishment. While wary most of the people who came regular, marine biologists who studied them, were friendly and the shoal was a much more social and less aggressive one than most.

At least partially due to the fact the island used to be inhabited and they had a shared community until a disease that the mers were immune to wiped out the island population. They still passed down stories and remembered them. The "strange" rituals that the biologists studied are the ones passed down to honor their former friends. Rituals that look religious in nature because it was as their former neighbors worshipped Primus.

All this adds up to Rodimus seeing Tyrest, who was slightly obsessed with it since he recognized a long defunct religious gesture in one of the videos a Senator showed him of "visiting" the island and believe it to be a sign, and swimming right up to him. Rodimus sees him do the gesture and returns it enthusiastically, swimming much closer than he would normally and even perching up on the boat's edge which led to him getting snatched.

Rodimus suffers during his time with Tyrest, who treats him like a pretty toy, and punishes him when he "acts up". It only gets worse the more time passes and Tyrest gets handsy. Rodimus becomes incredibly hostile to all mechs and Rodimus starts to get drugged daily to keep him placid.

Then he has his first heat and Tyrest is eager to take advantage of it to arrange for artificial insemination. It required getting him out of the tank though. The drug burns out quicker than Tyrest realized and Rodimus begins to become more lucid and once Tyrest dismisses his guards and staff for the day, Rodimus rips out his throat. Tyrest kept Rodimus in his private island, letting him look out at the sea but never touching it.

Rodimus drags himself through the house and across the sand into the water. He's hurt and bleeding and exhausted but he's free even if he's somewhere new.

Rodimus is not a very sturdy breed of mer or one meant for long distance or deep ocean travel on top of still smelling like heat. He encounters a lot of dangers from predators and other mers, reacting with almost feral aggression not allowing anyone, even friendlies close. He follows old stories and constellations to eventually find Nyon, or where it was. There was an accident and a ship carrying oil wrecked and the leak destroyed Nyon. There are mechs working to try and clean it, but the reef and shoal are dead and the pink sands stained.

Rodimus now heavily pregnant and strained with grief wonders blindly, avoiding the large stretches of territory or inhabited areas he goes through, and finds an island that looks mostly untouched, no mechs or mer shoals obvious and just falls asleep exhausted in one of the underwater caves.

The reason it is untouched is it is neutral territory where the "sea witch" Ratchet and his mate Drift live. Who find Rodimus, so exhausted he doesn't even wake up when they touch him, clearly having starved himself, undersized and with poorly healed injuries. They take him back to their cave and Ratchet quickly cleans his long neglected wounds and treats them, while Drift helps him feed Rodimus via mouth-to-mouth until he has enough strength to respond and swallow when they put it in there. He sleeps for days with their tending, tense and curled up even in his sleep until on the fifth day he wakes up.

Rodimus is incredibly wary of the two other mers when he wakes up. He is hissing and bristling and ready to fight, though instinct has him pushing himself back into the back of the cave and curling around his swollen belly. He is full and healthier than he has been in ages, and everything is screaming to nest.

Drift and Ratchet are soft. They've never managed to carry more than duds despite their long courting. They suspect they are wither infertile or incompatible. They have more than enough to support a carrier, and both have gotten a little attached while carrying for him.

They give Rodimus space, leaving him food and not forcing themselves close. Slowly, warily, he creeps out. They both freeze when he does, letting him make the first moves. When he creeps out further, Drift trills at him hopefully, which startles him and sends him rushing back into hiding.

It's slow progress with Rodimus watching them warily from where they've tucked him into an inner cave, and their instincts are acreaming to take care of him more and barely sated by glimpses and food and occasional glimpses of him sleeping and smelling content. Both are patient though.

One day, when it's just Ratchet, Drift, having gone out to hunt and patrol to settle some of his "expecting babies" instincts, Rodimus finally creeps out. Ratchet's own instincts to prepare have led to him overprepping in medicine and gathering a bit. He's been trying to prepare for any eventuality. He doesn't freeze or react when he feels Rodimus moving behind him and forces himself to remain calm letting him approach and watch Ratchet curiously.

Rodimus, meanwhile, has gotten curious about his not-captors. He has become absolutely certain they don't want what most have wanted from him and don't appear to be a threat. Mostly, they seem to want to feed him. He's been listening to them interact and talk but still doesn't understand why. He doesn't feel safe, but he also doesn't feel actively in danger.

So he's decided to approach the safer looking one alone. Drift may be smaller, closer to Rodimus’s size, but he's all predator with prominent fangs and claws and spines. Ratchet, meanwhile, is bigger than him but has duller claws, practically just nails and grinding teeth as well as non-prominent fangs and eats kelp as much as any fish. Rodimus is pretty sure his main defense is his thick hide, size, sharp tongue, and Drift.

They talk, and while it is tense, it soothes things. Ratchet explains how they found him, what he is doing, and briefly a bit about himself and Drift. He also offers Rodimus safety in their home as long as he wants to stay. When asked why Ratchet nods to his swollen belly and says he can't just let a school less first timer go at it alone when he can help and that Rodimus will need suport and be unable to hunt for himself soon enough. Rodimus has bee filling more and more the instinct to den down and prepare but is still suspicious.

Rodimus demands what exactly Ratchet wants in return, and he says for Rodimus to let him treat his wounds and make sure he and any pups or healthy before Rodimus leaves. If he wants to leave, that is. He also confirms Drift feels the same way. Rodimus still doesn't trust it, but Ratchet hasn't lied so far and had plenty of time to take advantage.

Drift comes barrelling in, freezes, and gets excited, sending Rodimus back into hiding. Dratchet talks about taking things slow. Or at least that's what they think until the next day. Rodimus is nervous at first but gets comfortable very quickly, and by the end of the day, he is acting like he owns the place. Which is at least 65% bravado, but he is forcing himself to be comfortable in order to convey confidence. Drift, of course, is thrilled and very friendly and readily spoiling him, eager to show off their home and area, and Ratchet is very tolerant and fussing at him to eat or drink.

Rodimus is surprised how quickly it turns to genuine comfort with them. He swims with Drift acting as sentinel, but always gentle and cooing as he shows them small wonders and races and dances around him in warm shallows that look perfect for pup. He hangs around Ratchet on his tired days lounging and pestering him when Ratchet makes medicine, and Ratchet huffs but explains or tells stories about his travels, which are interesting and pretty wide. Other times, they go to gather medicinal things. It's further than Drift usually takes him but Rodimus stubbornly demands to come and inevitably ends up dozing on Ratchet's back being gently carried home between them

He realizes as his room (den) becomes filled with pretty rocks and decrotive plants and soft sponges for a bedding and fine sand perfect for burying eggs and carefully selected rocks that both have given him that they've been acting both as sire and community and he cries and realizes he may be rwally and truly safe.

He starts being more open with them and laughing and smiling, and things get warmer and affevtionate as all three start falling for each other. Now that Rodimus is safe and his body isn't stressed he enters a new stage of his carrying and finds himself curling up against Ratchet in the cave not wanting to leave and purring or dragging Drift to his berth to cuddly and clunsy try and wrap his tail around him. Both of them pick up on it and smell it, but after what Rodimus said, they are reluctant to force the issue. Finally, after he half tucks himself under Ratchet and just vibrates while chirping, they do, and Rodimus realizes he's been making moves and decides rather than be embarrassed to go fully in.

They start assisting him, and when they do, they can't stop. It's a near constant pausing what they are doing to push him down and gently fuck into him while he purrs and clings to them, long pretty tail wrapping around them and clinging as much as possible. Both becime reluctant to leave him and he is firnly in the den napping most days and rarely venturing far. They prepare in earnest not to leave for awhile and the last two weeks of his carrying is just slow fucking, cuddling and constantly rearranging things to be perfect.

By the time Rodimus lays the eggs, they are all thoroughly mated and pleasantly surprised to find they hatch a mix of Rodimus's broght colors and white and red patterns.

That swerve angst I posted about like a day ago? Yea I made it worse.

The sire is IronFist, but he left before Swerve or him knew. They were sorta friends with benefits with romantic tension underneath. That shit flys out the window when IronFist just leaves one day. Shit really hits the fan though, when Swerve finds out he’s having a baby, then loses said baby to the DJD (aka Dominus Ambus).

So when the wreckers come abroad the lost light, swerve is hella pissed but just ignores IronFist as best as he can. Eventually he’s got no choice but to talk to him at his very own bar. This ends with IronFist probably saying something or joking about him just up and disappearing, which Swerve immediately dislikes and tells him off, saying how much he hurt the minibot. IronFist starts saying stuff defensively, like “we weren’t even really together why would it even matter now?”. Swerve goes blank for a second, then pulls a photo from his subspace, slams it on the bar table and just says, “it mattered to me and it would have mattered to them”. And it’s an ultra sound like pic of Swerves gestation chamber, with a barely formed sparkling clear as day.

IronFist has no words, and just looks at Swerve is disbelief and confusion. And when he finally manages to move his mouth , a breathless and strangled croaking noise escaping him, swerve cuts him off. Cold and hurting. “You left, and all I had was them. Then the DJD came and I had nothing. You leaving mattered the most to me, it hurt the most. But it’s fragging clear it didn’t really matter to you.”

Swerve leaves (his own bar!), leaving IronFist and the other patrons/wreckers to deal with the fallout.

Au where Kiloton is lowkey a mad doctor after his darling wife Megatron dies after birthing Overlord. Kiloton takes care of their son by day but goes crazy scientist mode at night and tries to bring his wife back. He does but something is clearly wrong. That is not your wife, Kilo, that is an eldritch horror(er- think Megatron as the unknown from dbd kind of)

Overlord is freaked out by his dads weird experiments in the basement

AGHH I love your cyberverse Hot Rod and bumblebee siblings stuff so much 😭 They remind me so much of lilo and nani! I need more of them fr!

Thank you gurrl2000 😊

- bumblebee is the short older sibling in some lifetimes

- hot rod is the taller chaotic younger sibling in dome lifetimes

- both have an extreme aversion to green energon. They don’t know why, the sight and smell just makes them disgusted.

- both have the same sire and carrier, Shockwave & optimus.

- they both have a love of sports. Roddy loves meteor shower suffering ( his outlier makes him attracted to hot things by nature and he’s pretty heat resistant ) while bee loves street racing and skateboarding

- both love a good car chase. They love to chase each other and play car tag.

- roddy used to act as a nightlight for bee when they were sparklings and bee would check in the closet for monsters for roddy

- both can’t stand mechs touching them. Bee frowns and looks visibly annoyed before saying back off. Roddy tries to play it cool and remove himself before disappearing with a joke and a smile. It works.

- they both have their carriers temper, its just with the matrix optimus chilled out a lot lol

- both sparklings took after their carrier in liking odd partners. Bee has starscream & roddy…he’s still in his slut phase till later on. Neither know about their carriers more “friendly mech” phase and optimus keeps it that way while lecturing roddy lol

- both know how to patch up a bot and revive them because of ratchet and uncle ironhide

- bee is prowls favorite between the two and Jazz doesn’t have a favorite but Roddy calls him out on it being Bee. Roddy isn’t mad tho because Bee is his favorite too lol
