A = Aftercare (What are they like after sex?)

• Admittedly, Depth Charge isn’t the best at aftercare. He knows the basics, that he should clean you up afterwards and make sure you don’t have any internal damage, but that’s pretty much all you get from him. If you need something, you’ll have to sweet-talk him into getting it for you. Get it yourself, is how he wants to reply, but he did do a number on you, so… fine. Being that he’s only ever had one night stands, he’s not used to his partners sticking around. If they do, if they find themselves wanting something more serious, he pushes them away—he really can’t stand the clingy ones. He wouldn’t be seeing much of the bot he was with afterwards, if at all, so he really can’t bring himself to care about how they’re feeling.
• You two aren’t exactly dating. The best way to describe whatever the two of you have going on is an acquaintances-with-benefits relationship—you’re not even sure he’s familiar with the concept of “friends” anymore. Normally, he doesn’t let anyone get close with him, but you’ve wormed your way into his spark, haven’t you? Yes, Depth Charge does care about you in his own way, otherwise this little arrangement wouldn’t be happening. Yet, he’s still incredibly distant even though this is the closest thing he’s ever had to a proper relationship. You can’t exactly complain. Realistically, you know being caught between two warring factions in prehistoric times isn’t an appropriate time to be looking for your soulmate. At the very least, you’re able to get the craziest dicking down you’ve ever had in your entire life. Still, you can’t help but wish Depth Charge wasn’t so detached…
• Depth Charge tolerates you cuddling up to him, but don’t ever expect him to reciprocate. It’s already difficult enough for him to show any sign of weakness, and in all honesty? He’s just not an affectionate mech, never was. He shows that he at least gives a damn by running a careful digit through your hair—kind of like he’s petting you—but only when he’s sure you’ve fallen asleep beside him. He doesn’t want you thinking you’re making him soft.
• He told himself he couldn’t afford to form attachments. He would never forgive himself if someone unwittingly got dragged into the mess concerning Rampage—he doesn’t trust anyone but himself to deal with it. Despite knowing better, he finds he just can’t turn you away like he’s done with so many before. The “relationship” he has with you, no matter how insignificant it may be to you, is… nice. Foreign, and a little frightening, really, but nice nonetheless.

B = Body part (Their favourite body part of theirs and also their partner’s)

• He’s never really considered himself that way. If he had to pick, it would be his servos, as they’re obviously what he uses to handle his weapons. He likes it when you bite or rub his audial fins when you’re fucking, so he supposes he enjoys them, too.
• Depth Charge likes your mouth. I mean, he really likes it. Whether it's on him or just looking at it when you speak, it doesn’t matter.
• His affinity borders on something dangerously close to obsession—your soft lips forming words, your tongue flexible to a degree unlike that of any Cybertronian’s, your saliva-slick teeth glinting in the light, your jaw opened wide to accommodate his spike…
• He should be disgusted. He was a little at first, until you showed him what you can do with your mouth. At this point, he’s convinced you somehow managed to rewrite some of his programming without his knowledge.
• Not really a body part, but he’s also quite fond of your back dimples, if you have them. He finds it interesting that some humans have a sort of ‘hold on here’ spot on their frames. Your back dimples are where his thumbs rest when he holds your hips as he’s fucking you from behind.

C = Cum (Anything to do with cum)

• Depth Charge’s transfluid is pink in colour and glows, is slightly watery in consistency and runs a little on the hot side. It tastes metallic and slightly bitter, and tingles on your tongue not too dissimilar to a carbonated drink. I imagine his lubricant tastes very similar, if not exactly the same. Tasting his fluids definitely takes some getting used to, but don’t worry, it won’t irritate your skin and it’s safe to ingest/have inside you. Probably.
• Since making it his life’s mission to hunt down Rampage, he’s given himself little time to self-service. Before meeting you, he hadn’t even interfaced since before it all went down. I’ll be touching more on this in “J”, but basically, since he had a habit of ignoring his urges for so long, he ejaculates a lot. No matter where he ends up finishing, it’s a given that you’re going to get some of his transfluid on you.
• He loves seeing his fluids dripping down your chin from either sucking him off or eating him out. When he overloads in your mouth and you open it to show him you swallowed it all? Get ready to have your pelvis shattered. Too bad CR chambers don’t work on humans.
• Depth Charge prefers to overload on you or in his servo instead of inside you. He isn’t taking any risks. If there is a possibility of Cybertronians and humans interbreeding, no matter how small, he wouldn’t want to put you or his mini-me in danger while Rampage is still online. In a perfect world without Rampage, (and one where Depth Charge never blew himself up alongside him lmao), he still wouldn’t be keen on having sparklings. Not in the slightest. Settling down with a conjux and a sparkling or two wasn’t something he ever envisioned for himself—or wanted, for that matter. He doesn’t like the idea of someone having to depend that much on him. Say you were unlucky enough to get pregnant. Congratulations! Depth Charge is going to get the energon now.
• As for your cum, well… there’s not much he can do with it. If nothing else, he likes seeing it splattered on the insides of your thighs and smearing it on your skin with his digits.

D = Dirty secret (A dirty secret of theirs)

• He’s been wanting to fuck you in his beast mode for a while now. Humans, he had learned, look ridiculous when they’re wet which for reasons unknown to him makes the energon in his fuel lines almost instantly flow south. Imagine him holding you in place with the tips of his wings, hehe. He has yet to bring it up as he doesn’t know how you would react. Mostly, though, he’s concerned about drowning you by accident.

E = Experience (How experienced are they? Do they know what they’re doing?)

• Depth Charge has some experience—far more with his spikes than his valve—from back when he was a security officer. He hasn’t interfaced at all since the incident on Colony Omicron, finding himself too focused on his mission to seek out any hookups. Fortunately, he still knows what he’s doing.
• As I’m sure you can imagine, he has absolutely no experience with humans, or organics in general. During your first time together, he was hesitant to even touch you more than what was necessary. He had never looked so unsure before. It wasn’t like your anatomy was all that different to his, he just didn’t think you would be so pliable. Like he could accidentally snap one of your joints without thinking. Seriously injuring you or worse was a real possibility with you being so much smaller than him and it took a fair bit of persuading that you weren’t made of glass.
• Although he was mass displaced to a more manageable size, he still wasn’t convinced, so you proved it the only way you could by lowering yourself onto him in one swift movement. In hindsight, maybe that wasn’t such a good idea.
• God—! You could feel him in your lungs! But you took all of him and you’re still intact, so that’s all that matters.
• Depth Charge let out a strangled gasp. A warning next time, for frag’s sake—he almost immediately overloaded like a youngling. He remembers the interesting rumours his colleagues used to spread about organics and never paid them any mind, but now that he was actually experiencing it? He wasn’t sure what he was expecting, but it wasn’t this. Your valve perfectly molds itself to his spike, you’re tight, silken, and most of all, you’re scorching inside. Slag, this doesn’t make him a xenophile now, does it?

F = Favourite position (This goes without saying)

• Assuming his back kibble won’t get in the way, Depth Charge is down for pretty much anything. Although he has a strong preference for being on top, he’s really a dom switch. He’ll act like he doesn’t like bottoming, but deep down, he enjoys it when he’s taken care of.
• His favourite positions are any that allow him to fuck you from behind. He likes the control it gives him and how deeply he’s able to penetrate you. Plus, he likes to pick on you every once in a while by delivering a single thrust so strong, it knocks you over and he has the nerve to chide you for being such a weak, little fleshbag who can’t handle what he gives you. If you have hair long enough to pull, it’s fair game for him when he has you in these positions. He’s also very fond of any position that lets him see the faces you make as he likes seeing what he does to you.

G = Goofy (Are they more serious in the moment or humorous?)

• Depth Charge is serious outside and inside the berthroom. He isn’t incapable of laughing, but good luck getting a small chuckle out of him, at the very least. If you make a joke or if either of you have an awkward moment, the most you’ll get out of him is the narrowing his optics disapprovingly at you or a slight shake of his helm accompanied by a tired sigh. Depth Charge doesn’t think that it’s the time or place to be making jokes while fragging.
• Once, you half-heartedly suggested he should keep letting Rampage get the upper hand if he meant he came back to the base angry enough to fuck you boneless and he genuinely considered getting up and leaving without so much as a word. He doesn’t know why he puts up with your slag sometimes.

H = Hair (How well groomed are they? Does the carpet match the drapes?)

• Depth Charge is a robot. He has zero hair. In terms of other forms of grooming, he doesn’t care about his appearance all that much; he has more important things to worry about. He likes to look tidy, but being the one with the shiniest paint job in the room doesn’t even make it on his list of priorities. Spending a few minutes in the CR chamber to sort out any scratches or dents is good enough for him.
• On you, he doesn’t care whether you shave or not. Not that you’d likely be able to in prehistoric Earth times. As a Cybertronian’s array doesn’t have anything remotely similar to hair, he might be a little surprised that you have hair down there as well and it would take some getting used to.

I = Intimacy (How are they during the moment? Are they romantic?)

• Depth Charge doesn’t see what’s so romantic about stuffing his spike (or both) in someone. He’s definitely not the bot to go to if you crave romance and there’s absolutely no chance of him pouring his spark out to you in the heat of the moment. He’s probably never uttered the word “love” before, and saying the words “I” and “love” and “you” in the same sentence would make his paint peel.
• Kiss him where his mouth would be as he’s fucking you when your foreheads are nearly touching, and watch as his optics widen slightly before he hesitantly presses his mouthplate to your lips. See, Depth Charge? Was that so hard?

J = Jack off (Masturbation headcanon)

• Before meeting you, Depth Charge wouldn’t self-service all that often. Like with many things, he found it to be a waste of precious time. He has a lot of pent-up frustration, and though he managed to learn to control his urges, they eventually boil over, the resulting heat pooling in his array nagging him for some much-needed stress relief. He strokes both of his spikes with one servo or buries two digits to the knuckle in his valve to the memory of past flings, using a bit more force than most would consider comfortable with the single goal of overloading in mind so he can get back to what he was doing before.
• After meeting you, he feels the need to self-service even less, because why would he need to anymore? He has you now. That being said, he won’t force you to fuck if you’re not in the mood. Fine. In his opinion, though, his servo and digits can’t compare to your tight, human valve or soft mouth and nimble fingers, but he’ll take care of himself, anyway.
K = Kink (One or more of their kinks)
• You know how most of the BW characters exhibit traits of whatever creature their beast mode is based on? I did some research and read that manta ray mating rituals involve multiple males chasing down a female. I feel like Depth Charge would have a raging predator/prey kink because of his beast mode and considering what it is he does.
• It’s not something he indulges in often, as there always seems to be some sort of Predacon activity within 50 kilometres of the base at any given time. But after a period of no activity from them, he deems it to be safe enough. He’ll take you to a densely forested area, nudging you as gently as he can muster in a certain direction and watches as you take off into the brush, giving you a three minute head start—he knows you’ll need it.
• It doesn’t take him long to catch up to you. Humans may be endurance hunters, but this is a highly-advanced, alien robot you’re up against. His audials pick up on your rather loud footsteps, whether you’re aware of how noisy you’re being or not, and he’s attuned to your weak EM field enough by this point that he has little trouble seeking it out. Were you even trying? (No. No, you weren’t, not when you know what happens when he catches you.) How your species made it as long as it has, he has no idea.
• “Gotcha,” he snarls in your ear, already mass displaced so that when he pins you, he doesn’t completely liquify your bones. You’re already soaked. Depth Charge didn’t expect you to enjoy this as much as he did. It seems your primitive instincts, despite lying dormant for thousands of years, still revel in the thrill of the hunt, even if you are the one being hunted this time. His spikes are met with little resistance as he takes you then and there on the forest floor like the animal you are.
• Wet clothing kink? Wet clothing kink. Being in or around water brings out Depth Charge’s 𝓯𝓻𝓮𝓪𝓴. He especially likes seeing you drenched in it. Remember that in “D”, I said that he wants to fuck you in his beast mode? Well, he figures that seeing you soaked head-to-toe in water is the closest he’s going to get to living out that fantasy.
• He made the realization well before you became intimate when the two of you got caught in a rainstorm. And by Primus, despite having tried to scrub the image from his memory banks, he’s not sure he’ll be capable of thinking innocent thoughts when seeing you wet ever again.
• He’s never paid much attention to the coverings you wear, understanding that it was some weird organic thing about hiding your frames. Hunkering down at the mouth of a cave to wait out the storm (at your insistence, he didn’t exactly see what the problem was), Depth Charge is finally able to get a good look at the state you’re in.
• By the AllSpark, you looked so… pathetic. Your wet hair clinging to your face giving you an almost feral look, your thoroughly-soaked coverings hugging your frame, leaving nothing to the imagination, and worst of all? It seems you decided to forgo a—frag, what was it called again?—bra today. Oh, slag, no. Wings bristling, Depth Charge is made aware of a problem he now has if his pressurizing spikes and his aching anterior node were anything to go by.
• “Wow, that was something else! That storm really came out of nowhere, right?” You laugh breathlessly as you wring water from your shirt.
• Thud. Thud.
• “Hey, did you hear that? That didn’t sound like the rain falling.” You whip around and peer nervously into the darkness of the cave.
• “It was nothing,” Depth Charge replied, a bit more hastily than he intended.
• You raise a brow quizzically at him. “Huh? If you say so.” Why is he looking at you like that? “Anyway, I hope this clears up soon so we can go back to the base. Wet clothes really don’t feel good. As a matter of fact…”
• You shuck off your shoes and pants, leaving yourself in your underwear and shirt only. Depth Charge wouldn’t mind, right? He’s a robot. They don’t work like that. What could the sight of your bare legs even do for him?
• Despite the chill in the air, Depth Charge’s cooling fans spin to life at the sight of your rain-damp skin. He silently thanks deities he doesn’t even worship that you seem to be oblivious to the more explicit side of Cybertronian anatomy.
• Filthy little ape. You’re doing this on purpose. Of this, he’s sure.
• Since he can get pretty rough, you’re bound to end up with bruises from his handling of you and his frame colliding with your body, or scratches from the sharp edges of his armour. Depth Charge unashamedly developed a small marking kink because of this.
• He was fascinated, and a little disturbed at first, by how easily he left behind traces of what you did together. He thought he was aware of his own strength, but apparently, you’re more fragile than he assumed. While Cybertronians do tend to leave marks on each other such as scratches, dents, and paint transfers, it’s generally cosmetic damage only and nothing to be worried about. The marks he leaves on you, though? Those are actual injuries.
• While you insist that you’re fine, that you’re not at risk of dying—he wasn’t concerned, for your information—it puts things into perspective for him. It all seems so contradictory to him. How can your frame be so delicate yet so resilient? A human’s protoform is thin and they have no armour; he’s amazed you aren’t constantly getting injured by your surrounding environment. You’re just so soft, and the way your flesh gives under his servos makes his spikes stir.
• The fact that he can mildly injure you from just holding you a little too tight, or cause you to shed a few drops of blood from brushing up against the pointier bits of his kibble has Depth Charge acting unwise. He’s grateful for the fact that humans have such inferior self-repair systems that it takes days for his marks to fade away; it gives him longer to admire them.
• I genuinely find it so funny when the fandom gives Transformers who don’t have mouths an oral fixation. But I honestly think it fits Depth Charge so well.
• He’s actually a little embarrassed by how hard and wet it makes him. His optics never leave your face when you go down on him and his intense stare never ceases to fluster you.
• Depth Charge couldn’t decide his favourite thing you do with your mouth if his life depended on it. Whether it’s when you drag your tongue painstakingly slow up one spike while you work the other with your hand, the wet, slurping sounds of you devouring his valve, the glow of his biolights in the dark cavern of your mouth or that trail of saliva that connects your tongue to his spike when he pulls it away… there’s no way he can choose.
• Sometimes, Depth Charge likes to seat you on his lap and explore your mouth with his digits as he ruts into you. It’s a bit of an odd feeling having the cool metal of his large digit press down on your tongue or sliding against your teeth. If you want to tease him a little, gently nip his digits or curl your tongue around them while making eye contact to elicit a quiet in-vent from him and cause his spikes to twitch inside you.
• Plant sloppy kisses to his spikeheads after he overloads, dribbling a mixture of your saliva and his transfluid over his softening spikes and watch him snap out of the stupor he’s in so damn fast. “Don’t tease me like that.” A growl emanates from deep within his chassis as he pushes you onto your hands and knees, spikes rapidly pressurizing again. You’ll feel like you got hit by a bus the following morning.
L = Location (Favourite places to do the do)
• I always wonder where Depth Charge goes in the show. Like, he’s never at the Maximal base unless he has to be there for whatever reason. I honestly think he just chills in the ocean so for the sake of convenience, let’s just assume he has his own quarters somewhere in the Maximals’ base.
• It’s not like he has many options on where to fuck you. He’s not on the friendliest terms with his fellow Maximals so the less he has to interact with them, and the less time he has to spend in that miserable hole they call a base, the better. True, he does spend most of his time out in the wilderness, but he does need to head back there every now and then for repairs and to refuel. Plus, that’s when he gets to see you. He refuses to fuck you anywhere else in the base other than the privacy of his berthroom. He’ll be damned if he’s caught panel-deep in someone, especially if that someone is an organic.
• You probably saw this coming, but Depth Charge really likes fucking you in the water. It’s almost like it invigorates him, he feels like he could fuck you for hours. He can’t exactly do it in his beast mode—he curses the fact that you need to breathe—but that doesn’t mean he can’t fuck you in the water at all! He understands the danger of submerging yourself underwater, even if it’s just for a few seconds. It’s one of the reasons his beast mode is off limits, despite the fantasy living rent-free in his helm.
• He’ll seat you on a rock just deep enough underwater that the lower half of your body submerged and pull you towards him as the panel covering his spikes retracts. Though he stands on much lower elevation to be level with your body, he’s tall enough that the water comes up to his midsection and you can just barely make out his pressurized spikes in the dark water. The water makes the stretch somewhat easier as he guides his spikes into you, lifting your leg and bending it towards you to allow him to go deep. With one arm holding up your thigh and the other by your head, you’re utterly caged against him like this. It’s strangely intimate the way you’re pressed so tightly together, and you swear that you can sometimes see what you think is fondness in his optics when he’s staring down at you—though you wouldn’t dare say it out loud.
• The little splashes of water the pumping of his hips create as he pounds into you sometimes spray you in the face which is mildly annoying—but then you think back to how Depth Charge looked so entranced by the rivulets of water running down your face and neck and dampening your hair. It isn’t so often that you see him like that, so maybe you’re willing to put up with it.
M = Motivation (What turns them on, gets them going)
• As has already been established many times before, Depth Charge has a not-so-subtle thing for seeing you wet. No, not like that, I mean literally wet. He can’t exactly put his digit on why that is. He figures it has something to do with the way being wet changes an organic’s appearance so drastically, something that doesn’t happen to Cybertronians. But also because your clothes become see-through. Do NOT let this mech see you after you’ve just finished bathing because there’s a high likelihood you’re going to get dirty all over again.
• Tying into his marking kink, show him your still-healing bruises from days ago if you want to provoke him into fucking you.
• The thought of you hiding the marks he left on you underneath your clothes and everyone is none the wiser haunts his processor. It’s like a secret only you and him know. And, oh—your bruises are a different colour now? That’s what they look like when they’re in the process of healing, you tell him. Organics and their inefficient self-repairing system. In a weird way, he’s grateful because to reiterate, it gives him much longer to admire the marks he made.
• Simply asking him “Want to fuck?” is enough to get him charged up, honestly. He likes when you get straight to the point.
N = No (Something they wouldn’t do, turn-offs)
• Depth Charge is a pretty reserved mech, so any situation that could result in getting caught receives a hard no from him. So nothing public or semi-public. Having complete privacy while being intimate is very important to him. The mortification at the thought of being seen or heard makes his plating crawl. He might not show it, but he’s pretty protective over you and is absolutely not open to sharing you with anyone. He isn’t even willing to discuss it.
• He won’t do anything you tell him not to do and he keeps a mental note of things you don’t like. He’s an asshole but he’s not a monster. Also, I mentioned previously that he likes marking you but he would never seriously injure you, even if you plead with him to. He always ensures he never gets too lost in the moment that he loses control over his own strength.
• Depth Charge already has an aversion to PDA and he strongly; dislikes it when you tease him in public. There’s no way he would willingly give any indication that he’s fragging an organic, not on his life. Besides, it’s just plain humiliating. Are you trying to embarrass him? Because it’s working. Attempting to get a rise out of him outside of the berthroom is one of the only times you’ll actually have Depth Charge mad at you.
• You stood near Depth Charge in the Axalon’s command centre, listening to Optimus drone on to him about something you really couldn’t care less about.
• Sensing his own boredom, you yawn in a slightly over-exaggerated manner, sidling up to him to trail your fingers up his inner thigh armour. Though you’re barely listening in on their conversation, whatever it concerns hardly sounds important. Feeling Depth Charge stiffen, you hope your wordless message conveys to him that he could be doing so many better things right now. Namely, you.
• Applying more pressure the higher up your fingers travel, you stand on your tiptoes to reach his modesty panels and trace the transformation seams. You barely make contact with the panel that covers his valve before Depth Charge seizes your arm in a near-bruising grip, digits completely encircling your wrist as he fixes you in place with a pointed glare.
• “What the frag do you think you’re doing?” his expression demands and you’re barely able to stifle the yelp that leaves your lips.
• You both quickly cast your gazes to where Optimus is standing. Thankfully, he’s still carrying on, reading something on a console and clueless to the little exchange that just went down.
• The wicked smile on your face tells Depth Charge that you think this is funny. Do you have any idea how close that was? How badly that could have ended for him? He’s lucky if he isn’t subconsciously projecting a flurry of emotions through his EM field right now.
• He ended up avoiding you for a while afterwards.
O = Oral (Do they prefer giving or receiving? How skilled are they)
• Depth Charge doesn’t have a mouth, so any possibility of him going down on you is completely off the table. Even if he did, he would much rather receive than give. He won’t ever object to receiving oral from you, having such a strong attraction to your mouth. As with most things when it comes to the berthroom, he prefers his spikes over his valve, but you won’t hear any complaining from him if you offer to eat him out. Either way, he has your mouth on him. Unfortunately, even if he mass displaces, he’s still too big for you to take both his spikes in your mouth, though you know how to make up for it.
• He prefers if you swallow his transfluid. Whenever he overloads and you clamp your lips around him and keep sucking, it’s like he’s offlined and joined the AllSpark every time.
• It was no secret that Depth Charge encouraged you to be rough with him whenever you took control. As if you could do any real damage to him, anyway. Well, one time when you were eating him out, you took it upon yourself to bite his anterior node. Hard.
• What followed were a series of the harsh electronic noises of that alien language of his, reverberating so sharply against the walls of his rudimentary berthroom you’re certain there’s no way the Maximals didn’t hear it—and he promptly overloaded so hard it was as if someone dumped the entirety of a bucket of glowing, pink paint over your head.
• “Shit, I–I’m so sorry, I hurt you, didn’t I?” Ears ringing, you withdraw from his valve as panic courses through you. You frantically search his faceplate for an answer, placing a hand on his cheek and staining it with his transfluid in the process.
• “You… I…” Depth Charge starts before going limp, steam visibly rising from the gaps between his armour and his optics offlining. Your anxiety is slightly assuaged when you realize he looks strangely… relaxed? As if that overload took years of stress off his pauldrons, his seemingly permanent scowl melting away and you dare say he even looks soft.
• But the moment doesn’t last very long as his optics online once more after a couple minutes pass—you can only assume he underwent a system reboot of some kind. Depth Charge sits up, looking around as if he’d forgotten where he was and what happened until his optics meet your eyes and… yep. There’s the scowl again.
• “…I have to go. That was a slagging waste of time. I shouldn’t keep X waiting.” He averts his gaze upon making eye contact with you.
• Standing to set about looking for something to clean yourselves with, he lifts you off him and sets you aside with an uncharacteristic tenderness. Okay, you’re starting to think you fried his circuits.
• “Hey, wait! So you’re not angry—?” You reach out to stop him so you can find out what the hell just happened but Depth Charge, the paragon of good communication skills, had already high-tailed it out of his berthroom before you could make contact with him.
• You get your confirmation that your activities were overheard when you enter the main living area of the base and are met with bewildered expressions flitting from Depth Charge, down to you, trailing behind him. Shit, even Rhinox looks appalled.
• No one says a word as Depth Charge storms out of the base, having given you an obviously half-assed excuse minutes ago about how much time he wasted when he could have been hunting down Rampage.
• Oh, you get it now. He’s not mad, just a little embarrassed, is all.
• A slagging waste of time, he says, as if he didn’t have the most mind-shattering overload since he came online, though he’s too proud to admit it. It’s not like it was your fault everyone heard, right? You never knew he was capable of making such a loud noise; you’re not even sure he knew.
• You don’t know where the hell he ran off to, but days go by until he returns to the base and acts like nothing happened. Later that day, in the privacy of his berthroom, you ask him what it was he said in Cybertronix that day. He doesn’t answer, instead dragging a servo down his faceplate while heaving a sigh which you take as your cue to drop the subject. Preferably forever, if you had to guess.
• Depth Charge knows he’ll never hear the end of it from Rattrap.
• A fucked up part of me considered that maybe it would be possible to ride his chassis but I don’t think it would be all that pleasurable. Manta rays don’t have tongues and the shape of his chassis-mouth wouldn’t be able to do much, so it would just be… nipping at you, ugh. Also, I know that the Maximals/Predacons can still emote with the head of their beast mode in robot mode (Megatron’s t-rex head-hand, and I think there was an instance of Tigatron’s tiger head rolling its eyes or something) but the thought of them doing that while you’re fucking is really unnerving to me for some reason, lol.
P = Pace (Are they fast and rough? Slow and sensual?)
• “Gentle” is not in Depth Charge’s lexicon. He’s rough with you, wants you to be rough with him and he has a tendency to manhandle (mechhandle?) you even outside of the berthroom. You are able to talk him into taking things a bit slower and softer every once in a while, not without him grumbling some sort of complaint under his vents, though. It’s probably just because he’s allergic to the intimacy of gentle lovemaking that fucking like it’s going out of style lacks.
Q = Quickie (Their opinions on quickies, how often, etc.)
• You generally end up having quickies more frequently than proper sex. It’s what Depth Charge typically prefers, him constantly being on the move. Usually, this involves you trying to get each other off as quickly as possible, with you jerking him off or fingering his valve (or both), and him fucking you with a single digit, which is already basically the size of a human cock. Sometimes, when he comes back to you in a particularly bad mood, he doesn’t even have the patience to fully unclothe you, content on just tearing your pants off and pushing your underwear aside to shove one of his spikes in—mass displacing not even being in the forefront of his processor. That is, until you're forced to make him partake in at least a little foreplay for your own sake, to avoid him tearing you in half.
R = Risk (Are they willing to experiment? Do they take risks?)
• In terms of experimenting? Not really, no. If it already works for him, Depth Charge doesn’t feel the need to try anything new. “If it ain’t broke, don’t fix it” and whatnot. He has his share of boundaries, as listed in “N”. He’s open to experimenting with positions or kinks that you bring up, but he typically isn’t the one to suggest anything.
• As for taking risks? Yeah, that’s a flat out no. Depth Charge already feels he’s like taking a risk by being so involved with you—he’s firm in his stance that you’re putting yourself in danger by being close with him. Plus, he feels like he can never get any damn privacy. His sad excuse of a berthroom is just a tunnel in the cave the Maximals call their base with very basic amenities—it doesn’t even have a door, for Primus’ sake. He’s well aware that any amount of noise is amplified in there.
• All this considered, the secrecy of his entire interfacelife is at risk, as far as he’s concerned. The risk of getting caught or the idea of fragging in public causes him to completely lose any charge he has built up. I mean, it’s not like none of you haven’t heard Blackarachnia and Silverbolt going at it into the late hours of the night, but the thought of someone overhearing him? With an organic? No fragging thanks.
S = Stamina (How many rounds can they go? For how long can they last?)
• What’s a refractory period? Depth Charge has insane stamina and endurance and you can’t convince me otherwise. At first, he didn't last all that long on account of not interfacing for a while, but he made up for it by being able to go round after round with next to no breaks in between. On average, he can last four to five rounds. At least, you think it’s around that amount because you’ve never actually been able to tire him out… that’s the maximum number of rounds you last with him before passing out from exhaustion.
• It’s kind of disturbing how he never seems to get tired—sometimes, just as sleep is about to claim you after an intense fragging session, you’ll notice that his panel hasn’t shut yet and… he’s still hard?! You understand that with Depth Charge being Cybertronian, he can far outlast you physically at basically anything. But even after that many rounds and after that long? That’s a little ridiculous, if you’re honest.
• Poor guy. I wonder how long he went without having his needs taken care of, you blearily think to yourself before you slip away into what feels closer to a coma than sleep.
T = Toys (Do they own toys? Do they use them? On a partner or themselves?)
• He owns none—he doesn’t have many possessions to begin with—and it’s not as if he can acquire any even if he wanted. His own servo and digits are enough for him, anyway.
• If you have your own toys, expect Depth Charge to protest if you ask to use your strap on him—not being in control puts him off a bit. C’mon, he’d scoff. What could that flimsy, human false-spike ever do for me? You don’t even have a spike, yourself. You sure you know how to use that thing? Then you make him eat his words, a particularly hard thrust from you has him gripping his makeshift berth so hard it dents, not trusting himself to speak as cries of harder and don’t stop threaten to leave his vocalizer. Depth Charge doesn’t beg. Fine, so you know what you’re doing. But it’d be a cold day in the Pit before he’d let himself moan and scream for more like a pleasure drone. He won’t give you the satisfaction.
• He’s a bit more open to using toys on you, though he doesn’t really see the point. Are his own spikes not good enough? You know his aft is the type to get jealous over your toys. He’s a little insulted that you asked him to use a tiny, human false-spike on you. He will say, though, that he has a mild interest in watching your pussy stretch to take the toy—he’s never been afforded this good a view when it’s his actual spikes inside you, that’s for sure.
U = Unfair (How much do they like to tease?)
• It depends on his mood, really. Most times he just wants to get straight into it, but he’s fully capable of being a little mean to you if he really wants to. He might delay your orgasms by pulling out just enough so that only the head of his spike is barely inside you—he gets some sort of sick enjoyment having you nearly crying out of frustration, begging and pleading with him to sheathe himself back in you fully. If he’s feeling especially unfair, he likes to ruin your orgasms completely, either by fully pulling out of you or his digits abandoning your clit just as you’re about to cum.
• You’re literal seconds away from coming undone when Depth Charge gets a certain glint in his optics.
• “You know, it looks like you’re not enjoying this all that much. Guess I’ll just get going, then.” He straightens up and begins to pull out of you, but your legs tighten around his waist because how dare he threaten to leave you like this?
• “N–no! No, don’t… don’t leave, please!” you sob, pitifully trying to grind yourself against him because you were so close. “You can’t—I was so… I need y–you back inside now or… or I’ll die!”
• Depth Charge rolls his optics. “Can’t have that. I didn’t think you needed it that bad,” he leers as he throws your legs over his pauldrons, nearly bending you in half as he buries himself to the hilt in one thrust.
• On the rare occasion you can actually convince him to stay put for a while, he even enjoys it when you tease and edge him, too. You’ll kneel between his legs or have him lie on his back, forcing him to keep his modesty panels shut as you lick and suck on his plating, only to pull away when you sense he’s close to overloading. You repeat this until his vox is laced with static and pre-fluids literally start leaking through.
• “Depth Charge…” A wide grin spreads on your face as droplets of glowing pink fluid begin to leak through the transformation seams of his panels. “You’re that desperate that you’re leaking for me?”
• “…No,” he denies, weakly rocking his hips as if to implore you to continue. His vox takes on that same growled inflection whenever he gets defensive and the sound of his cooling fans beginning to spin faster tells you all you need to know. That yes, he is that desperate that he’s leaking for you.
V = Volume (How loud are they? What sounds do they make?)
• Most of the sounds Depth Charge makes are quiet grunts, soft ex-vents, and the whir of his cooling fans. He isn’t all that loud when he overloads, either—a strained groan or a curse is what leaves his vocalizer. He’s pretty quiet, always able to maintain a good amount of control over his own volume. That being said, sometimes he just won’t shut up when he’s fucking you.
• This mech is a bit of a bully and some of the things he says to you are a little mean-spirited, but he doesn’t mean anything by it. “Annoyed” is kind of his default mood. Just like how he calls other bots snarky names more often than their actual designations, expect him to call you various names related to you being human, and fleshy—you’re not sure if he realizes he’s basically calling you organic slurs.
• Depth Charge rolls his hips, grinding his concealed array against your ass. “I know you were self-servicing when you commed me today. Couldn’t fragging think of anything else since then,” he hisses next to your ear, his chassis flush against your back as holds himself up with one arm, the other snaking under your waist.
• He doesn’t give you time to reply before his panel retracts and his fully-pressurized spikes slot themselves against your pussy. “Slag, you see what you do to me?” A low groan sounds from deep within his chassis as he ruts between your thighs.
• Unable to form any coherent words, you let out a high-pitched keen as he reaches a servo down and presses harshly on your clit, then withdraws it. “This is almost sad. Primus, you’re such a mess. You can hardly control yourself near me, can you?” Depth Charge tilts his helm, scrutinizing you.
• “You want me to treat you the way you want to be treated, is that it?” He places his servos on your hips to turn you on your back when you nod frantically. Now kneeling between your legs, he’s easing his spikes into you—something that’s actually possible when he’s mass displaced.
• This isn’t the first time you’ve taken both of his spikes, yet he still continues to watch with something akin to wonder when they leave a visible bump in your lower abdomen. “Frag—look at that,” he murmurs, reaching down to feel himself inside you.
• “Depth Charge!” you gasp, heat blooming across your face. “P–please, mov—”
• “Spikesleeves don’t talk,” he snarls, and he snaps his hips against yours so strongly it stings. You have a feeling you’re going to be here a while.
W = Wild card (A random headcanon for the character)
• He likes your jiggle physics. You couldn’t torture that information out of him, though. Never in his millions of years of existence did he think an organic body could have such an effect on him. He hadn’t come across too many organic species before and never considered that gravity could affect them in such a way. As Cybertronians are mechanical beings, this was a completely new concept to him—he shouldn’t be attracted to it, it shouldn’t do anything for him.
• Anytime you saunter around wearing form-fitting tops or barely-there shorts, you’re unintentionally giving him an opticful. And, Primus, it makes him feel like he’s sick in the helm for looking. He is not that kind of mech but his optics are kind of just… drawn there.
• Were he a lesser bot, he wouldn’t be able to hide his eagerness whenever you climb on top of him to ride him.
X = X-ray (Let’s see what’s going on under those clothes)
• Depth Charge has two spikes because I said so. But mostly because it just feels right. You don’t sound or act like him without packing some serious heat, know what I mean?
• They’re blue with smooth ridges, with the undersides having larger ridges the same purple colour present on his arms and wings. They’re both decorated with bands of yellow biolights trailing up to tapered heads. When fully pressurized, they stand straight out instead of curving towards his abdominal plating. The lips of his valve are purple and his anterior node is yellow.
• One spike is longer than the other, the longer being around 16 inches long when fully pressurized, and the smaller is about 12.5 inches long. You can’t wrap your hand around either at his full size. It’s possible to take his smaller spike safely without him mass displacing, but only around half way and after some size training. If you have any hopes of taking it all, some mass displacing would definitely have to be involved. You will not survive both of his spikes, otherwise.
• He won’t force you to take both of them at the same time—he knows it’s a lot for someone so small. As was implied in “E”, you definitely weren’t able to take both the first few times. Having one of his spikes rub against your inner thigh or stomach as he fucks you is adequate enough stimulation for him. His aft almost overloaded instantly the first time you took them both in their entirety—no valve he ever had felt anything like yours did.
• There really isn’t much I can say on the size of his valve. I guess it’s the size you would expect for a bot his height? You can definitely fit your forearm in it at his full size. Just be careful that his contracting calipers don’t snap it off in there.
• I struggled a bit trying to determine the size of his spikes, to be honest. I wanted them to be realistically-sized to someone of his height so I hope the measurements make sense. I linked the height references I used at the very end if anyone’s curious. However, I don’t know how accurate the latter link is because it says that Silverbolt and Blackarachnia are the same or a similar height, which is NOT correct, lol.
• A bit of trivia for anyone who cares—before doing some research, I wanted to be creative and base the design of his spikes off of whatever male manta rays were packing until I found out that their dicks, if you can call them that, are… kind of weird? Maybe it’s just me, but the idea of him not having a traditional spike and instead, he inserts one of his claspers into your pussy is pretty unsexy. Anyway, I decided to compensate by giving him two spikes. But mostly because two is better than one, right? Of course it is. Don’t even bother answering.
Y = Yearning (How high is their sex drive?)
• The irritation of having to deal with the constant annoyances that are the other Maximals, being stranded on this organic mud ball of a planet, his sheer hatred of Rampage, and being constantly on edge gets converted into a fair amount of sexual frustration. Depth Charge has always had a decently high libido which has only increased now that you have… whatever it is you two have going on. He’s raring to go more often than he isn’t. Just say the words and he’s on you.
Z = ZZZ (How quickly do they fall asleep afterwards?)
• Apparently, manta rays don’t sleep. Depth Charge is one of those “recharge is for the weak” bots, because he could be doing so many better things with his time—like trying offline Rampage for the nth time. He’ll recharge when he offlines, he says, and you really don’t like when he speaks like that because he seems so certain it’ll happen sooner rather than later. Hmm…
• On the rare chance you’re able to make Depth Charge get a few hours’ sleep with you, it isn’t without him putting up a bit of a fight first. What, are you my carrier now? At least he has the decency to make sure you’re the first to fall asleep.
• He always tended to have trouble falling into recharge, but with you next to him? His thoughts end up drifting as he stares at your peaceful form with an unreadable expression. Contemplating whether he could have done anything differently that day on Colony Omicron, the friends he’s lost, his mission, the war with the Predacons, and of course, you. Frustratingly, Depth Charge finds he can’t shake you from his processor sometimes. He wonders where he went wrong in life that you’re able to lower his guard to such an extent, how you manage to make him almost feel at ease—he can’t put it into words but it’s alien, and it confounds him.
• Grumbling to himself, he shutters his optics, trying to will his processor into quieting down so he can get some much needed recharge.




Here are the height references I used:
