I think the idea of getting it on with the insecticons and hearing shrapnel’s vocal tick closer to your ear when he’s pressing down on you seems hot as fuck. I really like them all having that little thing with their voices that makes them sound different from the average cybertronian, same thing with Astrotrain :3
My sweet child, you just gave me the green light to ramble on about insecticons nsfw. We are not getting out of here alive.
Insecticon mating behaviors on Cybertron
Premise: this whole thing was built out of the "cabbage patch birth" general headcanon according to which it's the planet itself that generates the individual sparks. Imagine there are literal birth hot-spots in which sparks are generated and aggregate matter to form a body (protoform). Then, they emerge as sparklings to be adopted and taken care of by the community.
In this sense, we could say that cybertronians themselves are infertile, and their offspring are generated not by interface, but by the planet itself, or Primus if you may.
However, in my headcanon, there are some species that have a certain degree of fertility. These species are the most ancient and more "animalistic" ones, whose mating does not generate sparklings per se, but is able to make the terrain prone to generating and thus resurfacing spark-containing protoforms.
In cruder terms, the transfluid fallen on the ground would be re-absorbed into the earth, making it fertile.
(Maybe one day I'll wake up with a different idea and decide to make a separate fertility headcanon involving sires/carriers, who knows)
Before the war, the insecticons were one of the most prolific races on Cybertron, given they mated quite frequently and stayed in territories that they protected and fertilized. Insecticon larvae would spurt out quite often, compared to other cybertronian species who relied on pre-determined hot spots.
Mating hierarchies, much like anything else in Insecticon society, were established through physical prowess. The weaker ones often took up a passive role; although there were instances of dominant and submissive behaviors appearing regardless of strength.
The Queen, leader of symbol of the Hive, was expected to take on a dominant sexual role as well, potentially mating with all members of the hive during their lifetime. From my older insecticon headcanon:
Indeed, during the war, the insecticons who sided with Megatron saw him as their queen and expected him to fulfil certain duties, among which there was mating. But well, Megatron let the opportunity slip (oof) and this causes resentment among insecticon ranks, which then culminated into the remaining trio to leave and try to cut all ties with the Decepticons.
This will answer the question in the ask. Sooo, given they're not quite cyber-animals and not quite modern cybertronians, they get the best of both worlds. So, they can make mechanical noises with their vocalizers and frame (see vocalization headcanons to know how modern cybertronians speak), but their speech patterns and vocalizations are still a little different from common cyberspeak. Indeed, Insecticon cyberspeak is considered both as a dialect and as a separate language, much like Sicilian or Neapolitan are compared to standard Italian.
This happens for two reasons:
The fundamental anatomical differences make Insecticon dialect favor certain sounds over others. In common cyberspeak, anatomical structures such as turbines, shacks and other mechanical components aid the construction of sounds that are integrated in the language itself. Insecticons lack certain anatomical structures in favor of others. For example, a fluttering of wings or the opening of the elytra is a sound of its own, which cannot be interpreted in common cyberspeak if not by translation. The shape of their throats and intakes further complicates the issue, given that even simple intake-only vocalizations end up sounding different (more distorted, hissed).
The territorial nature of insecticons caused them to develop a set of grammatical and phonetical rules that have evolved alongside common cyberspeak, without the two languages having many chances to mix.
To organic ears, the noise sounds eerily familiar, like something from a distant past which we've learned to discern through evolutionary means. Thus, insecticon noises appear similar to those of wild animals, sounds we've learned to fear and stay away from, or arm ourselves in case we encounter a predator. To us, it's more of a learned behavior. To cybertronians, it's more uncanny-valley territory.
But not all organics and not all cybertronians are the same. Some may be wired differently, silencing their instinctual fear in favor or something else. Or worse, basking in that same fear.
Indeed, some may find their peculiar speech patterns and vocalizations quite… alluring.
Shrapnel of all insecticons takes particular pride in his quirk, as it allows his voice to be recognizable and travel far distances through its echo. How is he able to create the echo? No one managed to get close enough to ask him, but we assume it has something to do with his ability to generate electricity. Perhaps an organ inside him that acts as a generator of mechanical energy, which is the able to create consequent electric energy when needed.
What happens is that, whenever he talks, the echo travels. Common cybertronians don't have the auditory equipment to discern that noise as friendly, so it sounds eery and crooked, nestling in the back of their processors like a screechy horror movie noise. But any potential partner who's not turned off by that noise will have the time to study it thoroughly.
It's even better when you consider that he wants to make his partner come undone with his voice, and his mouth, for that measure. He has an oral fixation (who can blame him) and if he doesn't have his intake on something he's not happy. So, there's the chance he will purposely push his intake close to your ear, nibbling it or pushing his face against your shoulders on nape. But you're going to feel those teeth either way.
His voice comes soon after, creeping into your ears or audials to make the thin hair at your nape, or the edge of your finials, prick up with instinctual fear and static. And he'll lick them, the fiend he is.
Of course, insecticon noises allow a vast array of chittering, chirping, and cooing. All clicking noises that tickle your audials deliciously if you can get your fear instincts to quiet down for a moment.
Bombshell's low voice is perfect if you're into low, guttural noises. If he keeps the mouthpiece on, his voice sounds muffled and the vibrations do the rest. His large frame allows for a great reverb, too. Textbook standard of the "deep, husky voice" hehe.
Kickback's way more varied array included a lot of chirping noises, sounds that despite their animalistic and uncanny nature, are meant to coddle you and make himself look less dangerous. There's a possibility he might want to use his outlier ability; in which the inaudible vibration of his antennae or wings influence the electromagnetic waves of your brain/processor, much like binaural tones are able to influence mood. His is not quite mind manipulation, but an ability based on the physical properties of sound. If his queen is moody or upset, he knows how to calm them down. With the sound equivalent of fruit stimming videos, ha.
Bombshell likes to drive deep before overloading, growling as he does, so much you feel like helpless prey (god I have EMBRACED this kink of mine). He overloads slowly, but likes to keep you there for a long time. If you're on top (and he likes it if you are), he'll thrust up to be as deep as possible. But will let you choose if you want to keep moving or just let him fill you.
Very obedient if you manage to show him who's the boss, despite having taken the role of temporary parent friend of the group for longer than he can remember. Considering this, he's been waiting for the role to be finally lifted, as he's convinced his precarious fill cannot be sustained in the long run. That's what you get for being the braincell of the group (Kickback also has one, but Kickback uses it for his own gain).
Can and will manhandle if you allow him. If he gets carried away, he'll understand what he did wrong and do better next time.
Most likely to give you active aftercare, helping you down if you're on top and carrying you to bed to let you rest. Will bring you food the next morning because his queen and partner deserves it.
Shrapnel is playful. Surprisingly sweet after you've tamed him, but also, he's the most feral. Will keep thrusting as he overloads, and he overloads hard. Will snarl and god help you if your skin is within reach of his talons, poor boy needs to grasp something.
Likely favorite position: doggy. Come on, he gets to frag you like the animal he is. But you need to keep him in control otherwise he might go too deep. Also, your shoulders and neck are within reach, which means he gets to nibble.
Oral fixation. Oral fixation. He needs something in his intake asap and this makes him particularly needy. If your hole is within reach, he'll find a way to put his muzzle on it.
Fuckboy energy. Lacks braincells, tact and finesse, but makes up for it with passion and enthusiasm.
Feed your damn insect, bitch.
Is also likely to purr while eating it, which adds a delicious array of vibrations to his ministrations.
Will definitely want to recharge afterwards, not giving much aftercare if not warming you up with his body.
Little shit. Plays the "love me I'm bapy" card to get cuddles and sex.
Kickback wants it fast and shallow, but also, holds you tight against him so it also feels deep. Is very attached and WILL keep you there until he's done and will demand aftercare too.
Is the most vocal among all, with an array of noises going from high-pitched chirps to growls and snarls. Normally he doesn't snarl unless lost in the sauce.
Speaking of sauce, I bet he'd love to be sat on.
You can do anything you want to him, really.
Despite his smaller and less physically imposing frame, he's one of the few insecticons that survived under Megatron's rule, which means he was cut out for survival in respect to many others who didn't make it. Back in the day, his position within the hierarchy was fairly decent, which allowed him more active sexual roles. After only three insecticons remained, he mostly took passive roles.
Which means that among all, he's the most likely switch.
Surprisingly enough, insecticons are very good at aftercare. If you're the queen, expect to be pampered and served, and have warm food on the table the morning after (which might consist of a bleeding carcass, but I mean it's fresh and the entrails are fuming, so feast on!).
They also tend to form cuddle piles to preserve body heat, especially if they perceive their queen to be running colder than they are. It's in their code to provide for their queen and protect them, and they tend to become very cuddly after they've been pacified.
Expect to hear purring and chittering noises while you sleep. Deaf silence is not a thing to be expected when dealing with the insecticons, but sooner or later you'll begin to find those noises calming (I mean, does no one here sleep with a white noise machine on?)
