"C'mere, you." Ratchet catches your chin with a servo, bringing your lips closer to capture them in a long-anticipated kiss. His other servo holds your lower back, inching closer down to cup your ass.

Moaning into the kiss, you wrap your arms around his neck. Hard steel meets soft fingertips as you play amongst the seams. The medic groans with you as he presses his glossa against your teeth, a gentle command exuding confidence that makes your knees weak.

A new set of metallic lips meets your body. It's a welcomed one, inviting your other lover in by tilting your neck just enough. The Prime licks and sucks at your already bruised skin, reminiscing of all the previous bouts of love poured over you. His servos find the side of your ribcage, running the tips over and between where they lie under your shirt.

"We missed you today," Optimus says breathlessly against your ear, nipping at your lobes, "I apologise for our busy schedule."

Parting your lips from Ratchet, who responds with a groan and a small flick at your lips with his glossa, you turn your attention to the mech behind you, "I don't care," You lift your hand to caress his face, "Just fuck me."

"With pleasure," Ratchet mumbles into your neck, having seized the opportunity to nuzzle himself against you. He dips his servos down to tug at the hem of your shirt.

"Here- let me." Optimus strips the fabric over your head, dumping it on the ground. Ratchet is next, reaching behind you to unclasp your bra. With hands as dexterous as his, he quickly does so and lets it fall from your shoulders.

Optimus groans at the sight, snaking his servos in front to cup at your breasts. They fit against his palms perfectly, as if you were made for him. He kneads them together, squishing and squeezing them. It causes a soft moan from you, and you lean your chest into his touch. His metal is cold to touch and sends a shiver down your spine.

"I'm takin' these off." Ratchet focuses his attention on your pants and dips his digits underneath. He grips your underwear, too, and pulls them down to your ankles to let you step out of them. As soon as he does, Ratchet's dermas are attached to your skin, and he kisses his way upwards. No stone unturned; not one inch of your flesh is spared from his opened-mouth kisses, worshipping your flesh like it's the last time he'll ever get a taste.

You can feel Optimus' impatience poking at your lower back, surely pent up from the stresses of leadership. You can feel your own arousal start to build at the thought of his impatience plunging into you. Rubbing your thighs together to ease some pressure, it catches the attention of both hungry mechs.

"Come on, Optimus," Ratchet grips onto your hips, standing up to full height, which seems to be miles above your head, "Let's get 'em on the berth; I'm far too impatient for mere foreplay."

Optimus agrees entirely, wrapping his arms around your midsection and effortlessly picking you up. He steps back until the back of his knees hits the berth, hauling you up against him. With a small surprised shriek from you, he flops back to lay fully onto the berth, your back lying against his chassis. Your other lover closely follows, climbing up to plant himself between both yours and Optimus' thighs firmly.

"Who's spiking first?" Ratchet asks, placing both servos onto your spread thighs. His optics hold the weight of cement, and he cannot look anywhere but your exposed folds.

"I will allow you first, old friend," Optimus presses his face against the side of yours, "I am sure our little love does not mind either way, hm?"

You nod, a desperate whine dragged from your throat when Optimus snakes his servo around to circle at your clit, "Yes, yes, I don't care, just- just please fuck me."

"I love it when you beg like that," It takes no more convincing from Ratchet to unsheath his spike. It's much smaller than Optimus but large and thick enough to keep you begging for more. He brings a servo to his mouth and spits on it before working his oral lubricants over his spike. Once satisfied, he leans down to kiss the inside of your thigh before letting his lubricants well up in his mouth and spits on your pussy. Optimus chuckles lowly at your reaction, allowing the warm spit to lubricate his digits to spread it all around your folds.

Once he feels sufficiently hard enough, Ratchet presses the tip against the threshold. He's too eager and can hardly wait a moment longer, "Oh, Primus-" He pushes further, slowly working half of his shaft inside.

He's barely seated inside you, and you're already trembling, resisting the urge to cry out. Optimus holds you steady, whispering soft praises and encouragement through it all.

"So well," Optimus watches with hazed optics as Ratchet sinks fully inside you, his digits continuing to work on your bud, "You take Ratchet exceedingly well."

Ratchet lets out a rough grunt, "Though a rather tight fit, might I add-" He leans his body over, making a sexually charged sandwich out of you, "But you feel like fragging silk." He shivers above you, and you've got no choice but to stare into his optics as he withdraws his length and thrusts hard back into you.

"Oh my god-" Your speech falters, and you arch your back against Optimus. Though not as fast-paced as the Prime, the medics feel longer and more powerful each time and ring your vocal cords like a bell.

"That's it-" Ratchet buries his helm into your neck, his work of breathing increasing with every plunge into your plush pussy, "Take it- take all of it."

Optimus chimes in, his voice strained with anticipation and longing, "They certainly are-" The driving force of Ratchet causes your back to grind and rub against his spike. He breathlessly nips at your ear lobe, "Tell him how he makes you feel, sweetspark."

"S-So good-" You moan, stringing together whatever words you can claw at, "Feels so good- nghn-"

"Yeah?" Ratchet grunts as he increases his speed. His grip on your waist tightens with every thrust, all indications point to his overload inching closer and closer, "Gahh- Frag, say my name-"

A filthy rendition of his name falls from your lips, slurred and full of lust for the mech. His thick spike is grinding and pressing against every sweet spot known to humankind. Your hands find his shoulder plating, gripping on for dear life as your own orgasm breaches the horizon. Optimus holds you steady and keeps you from squirming, letting Ratchet indulge in your flesh freely.

"Oh, you sweet thing-" The medic sits upright, pistoning his hips while hungry optics gaze down on your wobbling flesh, "So fraggin' gorgeous."

It takes only a few more pumps of his spike before you call out each other's names. Ratchet presses his pulsing spike as far as he physically can inside you, his frame shaking as he pumps full to the brim. Your body tenses, and your hands shuffle to find Optimus' servos, gripping them as you cross the threshold. The Prime responds by comforting you, intertwining his digits with yours, and murmuring praises against your ear.

"Primus, just when I- guhh-" Ratchet pants, squeezing his optics shut as you clench around him, "Just when I thought you couldn't get tighter." He taps a digit on your other lover's thigh, "Your turn. Ready?"

"Whenever you are satisfied," Optimus says. He snakes his servo to your front once again to prepare for Ratchet to pull out. With a strained groan, he does, and as soon as his spike unsheathes itself from you, Optimus shoves a digit inside to plug you up, preventing the flood of transfluids from escaping you.

"Here, let me help." Ratchet slips Optimus' spike out from under you. He presses the tip against your entrance alongside Optimus' digits, quickly slipping it past your folds, "There you go."

The Prime underneath you groans, vibrating your entire body. He grips your hips with restraint but with enough force to push you down his whole length, helped out by the slick of your pussy and Ratchets' transfluids. The sheer girth has you keening as your walls stretch and clamp down onto it. Ratchets' dermas are automatically on yours to capture your moans and cries.

"Primus-" Optimus lifts you higher onto his hips for a slight adjustment before he begins to move within you. The warmth of your pussy mixed with the hot transfluids has him clenching his optics shut and burying his face against the side of your neck, "You feel wonderful."

"They sure do, don't they?" Ratchet kisses your tear-stained cheek after your soft lips, "You're perfect."

Your ability to speak leaves you when Optimus gives you a particularly harsh thrust, and you cry out his name. Shaky hands find the ones holding onto your hips as you, once again, hold on for dear life as you're fucked for the second time tonight.

Ratchet sits up again, his lust-filled optics trained on the way your pussy stretches around the thick spike, how your face twists in pleasure, and how the drool inches down your chin. You're a complete and utterly fucked mess, and the sight of it all has his spike standing tall and erect once more. He bites his lower derma as he takes his aching spike in his fist and pumps himself, moaning with you and Optimus.

The Prime glances up from your neck, noticing his friend masturbating to you being fucked, "Not- aghh- finished yet, are you, old friend?"

"Never-" Ratchets' hips stutter, gritting his dentae as he squeezes himself from base to tip, "Never finished."

Optimus growls lowly into your ear, "Then we better give him a worthy performance-" He then wraps his arms tightly around your chest, causing you to forget how to breathe for a moment before he fucks up into you so hard you nearly black out. You no longer have control as he pinned your arms against you. He's unrelenting, rutting into you hard enough that the remnants of Ratchets transfluids spurt and dribble out of you. And the said mech groans in approval, jerking his cock faster and faster.

"C'mon, sweetspark," Ratchet edges closer to another overload, shuffling forward so his spike is within inches of your stretched-out hole, "Overload again- nghh- for us-"

"I- fuckfuckfuck-" You whimper out, unable to squirm or even move in Optimus' embrace. Your body starts to convulse, and your head falls back against the mech's neck as your whimpers bloom into sheer, unrestrained, and sinful cries, cumming around Optimus' cock.

"Primus, yes-" The Prime groans, his vocaliser strained. He pushes you down as far as you can take, dumping his load deep within your little organic valve. His own frame begins to tremble, jolting with every squeeze you give him. Your jaw goes slack, feeling every crevice within you filling up with with sticky transfluids. It causes a bulge in your stomach, a wonderous testament to how pliable your little human body is.

Ratchet is close by, desperately pumping his spike. His other servo finds your bulging stomach, caressing and pressing against it, "Frag yes, t-take it..." He moans wantonly, his second overload walloping him. Thick ropes of hot transfluid shoot out onto your stretched pussy, coating your outer lips and clit; some miss and shoot out onto your stomach. It causes another moan to leave your lips, the heat against your sensitive folds sending a tingling sensation up your spine.

He finishes himself off, squeezing every last drop from his tip before he sits on his heels, spikes brushing limply against your inner thigh. Optimus, once barely recovered from his overload, takes a moment to peer over your shoulder to gaze lovingly at the utter mess between your legs. A mess that they caused.

"Goodness," Optimus chuckles lowly, releasing his grip from your torso, "Look at the state you are in."

Your entire groin and everything in between is soaking in their sticky transfluids. It drips down your folds and along the shaft, still buried deep within you. It's a lewd sight, for sure, worthy enough for both of the bots to snap a picture and save it to their internal hard drives.

Ratchet breathlessly laughs with him, caressing your inner thighs soothingly, "Quite the mess, if I say so myself."

"It was..." You pant tiredly, your pussy still clenching around Optimus' dully throbbing spike. Your heart races, but you feel utterly relaxed against his frame as you soak in the afterglow, "Well worth the wait."

Optimus gives you an exhausted smile, kissing the side of your reddened and bruised neck, "I share the same sentiment."

"Speaking of, I hope we all share the same sentiment regarding getting you cleaned up," Ratchet shuffles back and leans down to bury his face between your thighs, licking a stripe up your drenched clit, "I'm peckish for dessert."

a ficlet for @cyberrose2001 and @azu-recentbrainrot . this is for u guys. U both infected me with him. I'm gonna sue. >:(

Ratchet/Human!Reader cunnilingus

painfully soft and fluffy compared to my usual writing. mostly just him eating you out until you fall asleep. mech was HUNGRY.

word count: 1,103

Ratchet was a bit of a hardass most of the time, and most people wouldn't deny that. But good god, he was incredible in bed. You'd heard stories about his party ambulance days, even seen photo and video evidence at some point much to your (very aroused) delight. Sure he was a little older and more battle hardened now, but he retained the passion. Not to mention… the battle scars only added to the appeal.

You spent more time than not at the autobot base. The other mechs had become more than accustomed to you at this point, and you'd even consider them all some of your closest friends. But, even though you loved them to pieces, your favourite time was when they were out on missions, or patrol.

It usually took no more than 10 minutes for Ratchet to start gently running his practiced servos over your form, and no more than 15 minutes for his mouth to be on you.

Today was one of those days.

His servos wrapped around your waist, slowly sliding up to caress your chest softly, squeezing the plush flesh softly. You immediately lean into his touches with an affectionate hum.

“Touchy already? It's been less than 5 minutes, you're so impatient…” You turn around so you can glance up into his optics. His usually bright, kind eyes have darkened ever so slightly and he has what can only be described as a cocky smirk on his face.

“I've been waiting cycles to have you all to myself again…” He mumbled, gently lifting you into his arms. Despite having mass displaced, he was still around three feet taller than you. He pressed kisses to your neck as he walked you to his berth, biting your shoulder gently, his dentae leaving a small red mark. You gasp in surprise, biting your lip to hold back a more embarrassing noise. He lets out a soft laugh “Primus… you're so soft and small… and so fragging sensitive.”

The medic laid you on the lightly padded berth, his servos trailing over your body with practiced delicacy. If there was one Cybertronian to trust with your squishy human form, it was Ratchet. Digits pulled at your clothes, fabric being pulled off with surprising urgency. He wanted you, and he wanted you now.

Your underwear were pulled off quickly, the damp fabric gently held between two digits before he slipped it into his subspace with a grin. You couldn't help but blush, and you felt yourself get wetter.

Ratchet's servos gently pushed your thighs apart, a digit trailing up your slick folds to gently ghost over your clit. He used two digits to spread you open, examining the glistening threads with a hum. “Dirty thing… you're absolutely soaked…” He held up his digits, spreading them apart. Strings of fluids practically dripped down his fingers onto the berth below. “and here you were calling me impatient?” He tutted disapprovingly, reaching up to slide his digits between your lips and into your mouth. You let out a shocked gasp, the slightly sweet, bitter and salty taste of your own fluids mixing with the sharp metallic taste of his plating on your tongue.

Ratchet's digits slipped out from your mouth, reaching back between your legs to rub your own saliva against you, before he leaned down to drag his glossa up your folds. Your back arched, one of your hands clasping over your mouth instinctively. His servos wrapped around your thighs, pulling you as close as possible. He moved his glossa against you like your slick was the finest energon.

Your legs clamp around his helm, and he growls. “That's it sweetspark… you taste so good…” His optics flicker as you meet his gaze, and you can feel him smiling against you. His glossa flicks against your clit, and you yelp. He chuckles again, one servo gently kneading your thigh as the other slides up higher. One large metal digit gently teases your opening, slowly inching its way inside. His glossa lapping against your clit the whole time.

His fingers are massive. Even in his mass displaced frame, his servos easily cover your entire abdomen. One of his digits feels like it could easily be the size of two of your own. The stretch isn't painful, but by god is it a stretch. His digit pumps slowly, but skillfully. He hits every spot inside of you with a surgical and practiced precision. You wouldn't be surprised if he mapped out all your sweet spots and kept a guide in his memory bank for times just like this. Which, to be honest, is a very Ratchet thing to do. He was a master of bringing you to your peak almost embarrassingly quickly. The way he looked up at you with that fucking look in his optics was not helping.

Your lower stomach twists, your thigh muscles clenching and twitching. You squeeze your legs around his helm tighter, and you can feel yourself clenching around his digit. You're so close. So painfully close. “H-hah… Ratchet…” You can barely recognise your own voice with how desperate you sound, and he chuckles softly.

“There, there sweet thing… you're taking my digit so well…” He mumbles, curling his finger up just right. His thrusts increase in speed, hitting your g-spot with each movement. His free servo moves up to your abdomen, pressing down slightly in a way that makes your eyes roll back. His engine purrs. “That's right… overload on my glossa for me sweetspark…”

You do just that.

With an embarrassingly loud cry of his name, your thighs wrap around his helm even tighter, to the point you're almost definitely bruised. You grind against his intake entirely unconsciously. He groans as he works you through your orgasm, relishing in the taste of your orgasm against his glossa. Your breathing slowly returns to normal as you relax your legs, trembling slightly. “F-fucking hell…” You curse, pushing the hair out of your face.

He chuckled again, pressing a quick kiss to your slightly overstimulated clit before he pulled away. His derma glistened with a mix of oral lubricants and your own fluids. “Good job, sweetspark. You're always so good for me.” He moved up to lay next to you, pulling you close to his chassis. His engine rumbled softly as he gently petted your hair, rather affectionately.

You were half asleep by the time he slowly stood up from the berth. He planted a gentle kiss on your forehead, mumbling something that you couldn't quite hear, before he headed off back to the main room, leaving you to nap peacefully.

[transformers-spike]

"Is this why the Autobots are fond of humanity? To indulge their sweet heat cycles? How many human mates has Optimus taken for himself? It seems as though their motives to protect them were never altruistic, much less noble." PLEASE, PLEASE GIVE US A SUB-STORY WHERE THIS TIME IT'S OPTIMUS AND A HUMAN SO IN THEIR HEAT CYCLE PLEASEEEE

Idk am I creating a humans in heat universe for the TF Fandom? I know people like making the bots go through it but I think the humans being affected is so much funnier. Just begging these massive robots to fuck us lmao

How must it feel to burn from the inside out? Betrayed by your own body, rendered unable to function by the fire in your core. You described it as an aching, an insatiable need to appease the hormones overtaking your nerve endings. A mere touch is enough to worsen the ache, it’s what your body dictates in the throes of a heat cycle.

Cybertronians are forged by Primus Himself, their interfaces exist for recreational pleasure and bonding, but your species is biologically programmed to reproduce, like most of the fauna of your planet. It’s a systemic sacrifice, one rendered obsolete by the sentient status of your species. Drugs have been produced to suppress your heats, or at least lessen the effects. Unfortunately, among a dozen varieties of medication, you are either allergic or completely immune to them, leaving you susceptible to your hormonal whims. He is sorry. You must go through so much pain every few months, but you barely show it, brushing off his concerns with a laugh, saying “it is what it is” and moving on as though your body isn’t on a timer. He admires you for it. In spite of your discomfort, you haven’t given up. Once, you told him: “So what if they don’t work on me? I just gotta roll with the punches and hope for the best, it’s been my M.O. since I got the damn thing.” Meeting them for the first time… was turbulent to say the least, but you’re safe and sound, relocated to Jasper, having adjusted to your new life with the help of Agent Fowler. You’ve told them many times you’re infinitely grateful to be in their lives (barring the near death experience at the servos of an Insecticon). For them it’s a pleasure to ease your burden. You’ve eagerly established your consent, although only Arcee is the right size to properly take care of a human. Digits and glossas can only do so much compared to a spike. He tries not to pry, your privacy is yours to divulge at your leisure, but he cannot ignore the charge building up behind his interface when he sees you with the others. Yes, he is an occasional participant, but he will rather cover shifts and allow them some well-deserved respite in your berth. They deserve it. He dares not imagine Arcee’s spike pumping in and out of you, satiating your aching body, filling you to your limit as you beg for more. 

Your scent lingers in the air, caressing his sensors, a gentle hand tugging him along by the servo, pulling him in your direction. They try to keep it to themselves, but his team is beyond a doubt intoxicated by your presence alone. Thankfully, it has (almost) never impeded their judgment during missions; perhaps it has even served as motivation to make it back to base in one piece. He tries to ignore the gleam in his old friend’s optics after quelling your urges, if only for a night. Or Bumblebee's praises coming to you as a slow stream of beeps while he nuzzles your face. Or Bulkhead cradling you to his chassis like a precious artifact as you discuss what late night movies you should watch. Or catching Arcee kissing you over the mezzanine and pulling back with a smile she hasn’t worn since Cliffjumper’s death. You bring them together in your own special way, even if you blush and sheepishly deny it, claiming you should be thanking them instead  Recent discoveries have yielded an impressive increase in energon and brought forth new opportunities. With unparalleled quantities at their disposal, they can now mass displace. The transformation is no small feat, it exhausts their system and rapidly drains their energon level. But he will not forbid Bumblebee from using it to play with the kids as long as it’s not in excess. Nor to join you during heat cycles. Much like Bulkhead. And Wheeljack. And especially Ratchet. Primus forbid, his old friend has every right to enjoy himself to the fullest after all of his back-breaking work. He’s been meaning to pay you a visit, but he hasn’t found the time until now. In the temporary abode you set up in the base, away from the prying eyes of the kids, you prepare yourself for another heat. Some refurbishing was done to meet your needs (in no small thanks to June Darby and agent Fowler’s financial help); the mattress and the mini fridge was a given, but you’ve added a variety of personal belongings and entertainment; a television, a writing desk, a few “bean bags” here and there, and a pile of old magazines to scrapbook. He wonders if you consider this place your home more than your actual house in Jasper. You greet him while downing a bottle of water, holding up your hand to signal for him to wait. Once emptied, you place it next to the mini fridge, among a wide array of bottled water crates. That would explain the groceries June had brought in with Arcee’s help. As a medical professional she’s especially fretful over your condition, doing her best to prevent the risks of heat cycles, bringing you plenty of calorie dense fuel to combat the massive loss of nutrients. He has not forgotten the fear they experienced when they found you shaking from the deficit, having completely overlooked your hunger in a midst of desperation. In this form, he can appreciate the full extent of your body without fear of hurting you, kneading the supple flesh beneath his digits as you giggle and pull him into you. He does not tower over your reclined form as much as he encases you in a careful hug, hearing the rapid thrum of your human spark directly against his audials; he may sense your pulse rate, but experiencing it is a new wonder of its own. You tell him you missed him and you wish he would let himself go and come out to “obliterate your pussy” more often. He nods and apologizes for his absence even as you shush him and insist he enjoy himself as well. He is… the largest Cybertronian you’ve taken, you remark while adjusting to his size.

“Except maybe Wheeljack,” you add cheekily, already bucking into him. Your composure evaporates as he works you up, not to say that he is much better. He steadies himself over you, charge trickling down his interface as your walls clench around him in a vice-grip. You beg him for more, plead that he frag you until you can’t take it anymore, but he has grown used to your requests and knows when your body has reached its limit. You whimper and claw at his back plates, flush against his frame yet dragging him closer as though to merge your human spark to his.

If only he could.

Slow and steady, he frags you through your overloads, each one adding a new surge of spark down his frame until he comes to his end. You are small and shaking, but in this form he can properly hold you against his chassis and comfort you through the afterglow, bringing you another bottle of water and a Clif bar (chosen for the human scaling a mountain with “If you eat this you can kill God” in big bold letters).

You stir and sit up on shaky knees to accept his offerings. Halfway through your meal, you eye him up and down.

“Are you going to stay some more?” you ask with hopefulness, still chewing on the “ultimate nuts and banana power” concoction advertised on the packaging.

“I’m afraid not, Ratchet has been hard at work deciphering Decepticon encryptions, I will be taking on his duties for the night,” he tries to break it gently, expecting crushed expectations, not your bemused expression looking up at him.

“So you’re sending him my way?” You give a chuckle. “Wish we could have spent more time together, but work is work. Just…” you crawl into his lap and hug him as tight as you can, head resting against his chassis. “Please come back tomorrow. Or after tomorrow. I miss seeing you this way. I won’t get between you and… whatever you have going on, but please visit me more often. You have no idea how nice it feels to be around you.” His gaze softens, glowing faintly against your hair. “So I’ve been told,” he says, a smile on his lips. “As long as it lightens your burden.”

Ratchet x Fem!Reader

SMUT MDNI 18+

--------------------------

Description: Ratchet offers to pick you up after an "event" at a friend's house. Arriving and seeing you walk out after he initially said bye to you that night, he sees just what kind of party it was and what you wore to it.

Warnings: Maybe OOC, horny, lots of describing of the reader's outfit. No penetration, and not really descriptive of smut, but it is there, I promise.

A/N: It came to me in a dream, and I just had to write it; I hope I did our lovely doc justice. Also, don't be mad that I cut off the good stuff; maybe I'll do more like this if you guys actually like it.

Words: 874

--------------------------

He didn't know what made his helm hurt more: the thumping music from the giant house he was currently parked in front of or the strobing lights bleeding through the windows and open doors. He's getting more irritated by the minute of the thought of his cover being blown; it's a bit odd for an ambulance to be sitting outside of a human habisuite, especially if it is not there to take care of the injured or for an emergency. He almost texts you again until he sees you strut out with multiple locals surrounding you; he has to do a double take and just about reset his optics. His engine revs up at the sight of it, a high-collared white latex nurse uniform that stops above your thigh, paired with the medical cross in orange, his orange. Your nurse's hat has the same cross in orange; your white tights lead down to a pair of black heels. Primus, seeing you just made him want to grab you in front of everyone here. Your head turns in his direction at the sound of the engine, and you wave at him. The people surrounding you looked over at him as well. He flashed his lights a few times, and you smiled back. You waltz up to him with a few others still trailing behind you, amazed that you had an ambulance for a ride.

"How the hell did you get an ambulance?" One of the boys by you asked while you started touching the hood of Ratchet.

"My lover owns it, and let me borrow him for the night." You tell him while pushing your body more into Ratchet before hopping up and sitting on his hood. You continue to rub him while you chat with the last few curious people about your ride. All the while, Ratchet was trying not to overheat from having your ass directly on him and not being able to do anything about it. You say your final goodbyes and slap Ratchet before jumping off and entering the driver's seat. You drive in relative silence, waiting for him to complain or even fuss.

"Is your underwear my orange as well?" He starts evenly, and you have to steel yourself not to drop your jaw at his boldness.

"Did you take a hit of synth-en before you came and got me?" You tease while gripping the steering wheel; you can feel his gaze on you even though you don't know where he's looking from in his alt-mode. His engine hums a bit louder before he speaks again.

"Are you even wearing a bra?" he asks lowly. That dress looks so tight." You are grinning so hard at his crassness tonight; you love it when he drops the 'I don't care about anyone' attitude.

"Wanna see the answer to your first question?" You ask as he stops in front of your garage, and never have you been more grateful to live a bit farther from town than now. He turns off his headlights, and you take that as your cue to spread your legs; he moves your seat back a bit, which makes you let out a little squeak. He lets out a little sigh while looking at you. You run your hands down your chest to give him a little show before you show him the answer to his second question. You drag your hand back up your chest and then to your neck; you grab the zipper and slowly pull it down your body. You stop halfway down your naval, slightly pushing the fabric away from your chest. You heard him let out a soft gasp.

"So, doctor, what is your diagnosis?" You ask him sweetly while leaning further back into his seating, spreading your legs a bit further while playing with the edge of your dress.

"Well, I'll have to take a closer look," he tells you. You unbuckle the seat belt, fixing your dress just a little bit, and he transforms back to his bipedal mode. He leans down to your level and then scoops you up in his hands, holding you close to his face, smelling you, and rubbing you against his intake, giving little nips to the bare area of your chest where you opened it originally.

"Mhm, such a pretty nurse you are." He whispers close to your face while giving you little kisses.

"Every doctor should have one." You giggle back before moaning when he nudges his faceplate between your legs; he moves the fabric to the side so he can taste you better. Arching your back into his large glossa, you grind into him while he uses one of his digits to rub your chest. He keeps rubbing and licking and sucking until you gasp and let out a shout of his name. He slows down his ministrations on you; while you catch your breath, he moves to lay against the side of your house. You watch him while you calm down before patting his servo, holding you, and sliding down to his modesty panel. You give him a few grinds, and he groans in response before you stop and smile up at him.

"Care for me to give you a little check-up?"

______________

"Hey Rat, got your equipment!" A voice calls out from the entrance of the medical lab, multiple sets of optics shoot to the human who reads through the list of equipment that was needed.

Ratchet's vocals crackled with static as their sweet voice tortured his processor, the haze of his rut had made it nearly unbearable to be around any of the other mechs on base without him wanting to rip their helm off. His plating clamps uo agonisingly as he turns to the human.

Optics watch their every move as they walk through the lab, every mech's optics flicker over their form. Dimly he registered a medkit, blood samples and other equipment clutched to their chest.

A soft whine escaped his venting as the sweet yet nearly sickening scent of hormones waft from their frame. They smile, making their way towards the medical staff with the supplies. "Here those blood samples you requested, hopefully this can help you understand what about our biology seems to keep making you guys go into rut" they call out while checking over their list. “I wasn't able to get any Electrum samples after that fight with the Cons. There wasn't much left at the scuffle” they call back, Ratchet optics focus In on Perceptor and Hoist as the two begin sniffing the air.

Through the haze of full-blown interfacing protocols, Ratchet lefts out savage snarl peeled from his vocalizer at the collected optics of his cohorts. Hoist, Starscream, Perceptor and Shockwave back off, but they sling around the lab, trying to make themself look busy.

Dimly he registered supplies in tiny hands, he took them as softly as he could from them, his frame shuttering in delight at the slightest contact. A harsh keen escaped as servos servo lifted them up onto the table. It makes them laugh softly as they shake their head at him "Settle Doc, they aren't doing anything" they call out while moving about with different vials, looking at the different colours and liquids in them. Once again the others in the lab try sneaking closer.

Another savage snarl tore from Ratchet's vocalizer at the gathered mechs, plating clamping up as his servos dent the table. "Back, the lot of you!" he bellowed, a dampening field flickering with repressed urges. His Optics cycled rapidly between the crowd and their movements.

His vocalizer spat harshly "get out Now," he rasped through grit denta. The others didn't stick around after Ratchet snarled, all of them quick to leave the medical bay. A low keen escaped his vocals as he slams the door locked, servo pressed against the metal as he cycles another vent while pressing His helm against the metal trying to calm his systems down. He stands there for a moment trying to get a hold of himself before his optics shoot open as he marches himself back over to them.

A gasp leaves them as Ratchet grabs them by the hips pulling them closer "Easy Ratchet, easy!" They call out through a shaky breath as their fingers dig into the Ridge of his plating eyes focusing on his optics, watching the way they shift and flicker as he looks at them than the lab.

Ratchet shuddered violently at the proximity yet dared not release his deathgrip on their hips. Every part of his coding was calling for one thing.

Claim. Breed.

His helm nuzzled against them unconsciously, massive frame quivering with repressed force that could crumple their fragile body. The scent, the warmth and the softness has Ratchet keening softly into their shoulder, nipping and sucking the skin.

" That's bad huh?" They ask softly, one hand trailing his neck cables as they hold onto him, they knew the rut cycle was chipping away at Ratchet's sanity and restraint; they just hadn't realised How badly it had affected him. Their other hand moves his faceplate, leaning up catching his lips in a kiss as they hold him in place.

"Please." His voice box grated a ragged plea, servos trembling with a need to touch to claim. "Can barely contain protocols - damage you, never forgive myself.." His engines snarled in need. It's a miracle either of them make it to the medical berth, but the moment they do Ratchet is on them. A savage snarl tore free as he seized their delicate frame, servos tearing through clothing as if it was nothing.

His intake trails across their body kissing, licking and savouring the taste of their skin. His frame caged them against the berth, A guttural rumble leaves him as he admires their naked body.

"Ratch lay down now" they demand. He follows the command without a second question, servo guiding them to sit atop of his frame. their fingers run across the seams of his chassis and further down his body. "Mmm good boy" they praise, leaning down to press a kiss to his frame.

Their hand moves to his interface panel, running along the hatch. "Come on handsome, you know you want me on your spike you don't need to hold back anymore, let me look after you" they coo as they move further down his frame. A tortured keen ripped from Ratchet's ragged vocals His optics flickered, fields pulsing in need. His interface panel snaps open, Ratchet hisses as the pressure finally releases, a deep moan follows as smaller hands wrap around his spike.

His servos curl around their hips as they slowly work his spike with their hands and mouth. optics fixate on their backside as he squeezes the flesh of their ass, adoring the small gasp that leaves them. they pull away enough as transfluid runs down their chin and Ratchet's spike. They watch the way the shimmering liquid leaks and pools into the seams of Ratchet's frame.

"Use your words baby, can't help you if you don't tell me what you want" they chuckles as they press a kiss to the side of his spike, running their tongue up the length, lapping up the pretty pink fluid that leaves his frame. "Please - ah, please!" he managed to force through gritting denta, grasping desperately for a coherent thought. His spike throbbed in need with each touch.

His intake fluttered futilely, field pulsing arrant pleas for the relief he drags them back away from his spike. Spreading their thighs, his glossa runs between their thighs before he pulls them back onto his face. A deep guttural moan leaves him and he works his glossa into them.

Gasp and moans leave their lips as the hunch over face pressed into his chassis as Ratchet eagerly eats them out as if it were his last meal. "Inside - need to fill you up! Frag, need you" he mumbles against their trembling body.

Ratchet emitted a pained keen as he withdrew his glossa, spike throbbing with a need to fill and claim. He lets out a purr as he positions them, A stuttering exvent escaped his vents as he slowly presses in, his engine roars in delight, intake snapped open in a soundless cry, frame clamped rigidly as he begins to grind into them.

“fuck Ratchet!” they cry out as he holds them in place. His optics focus on their stomach bulging from the size leaving a very visible outline of his spike, it makes an old part of his coding coo in delight seeing them so full. He slowly begins to pull out and press back in each movement as he holds back snarls as he tries desperately to be gentle.

A desperate keen tore from Ratchet's vocalizer as they slowly rose, then sank once more upon his throbbing spike, transfluid already leaking from their body running back down his spike as he pulled them down hard. A sharp yelp leaves them which makes Ratchet cease up for a moment. “I'm alright, I'm alright, please don't stop feels so good!” They call out trying to reassure him.

His servos curled tightly upon straining thighs, guiding each plunge to fully sheathe his spike within them. Optics blazed transfixed on their body and how used they looked, stomach bulging, his transfluid gushing from them yet he hadn't even overloaded yet.

Another guttural moan leaves him as he frantically grinds into them, each thrust leaves them breathless, thighs quivering with each movement. Gasp and cries leave them as Ratchet ceases up, their name falls from his lips as he pulls them close. They whine loudly as transfluid floods their smaller body, gushing out onto ratchets' lap and the medical berth. A deep purr echoes from Ratchet's chassis as he holds them steadily against his frame.

Ratchet vented ragged exhalations as they lay against each other, condensation and sweat coating both their quaking frame moulded closely to each other, his little lover's breaths are just as ragged as they whine into his plating, cuddling close to each other as Ratchet holds them close.

His spike remained fully seated within them, throbbing and twitching involuntarily with aftershocks of interfacing. His Sensory nets drunk on the mingled scents now permanently coating their body. They smelt like him, and it made a part of him content.

One massive servo curled tenderly against the small of their back, cradling them against his chassis.

"Feeling better?" They tease softly, only to gasp as he pulls them back against his spike making more trans fluid gush from them. A deep rumble leaves him in delight. "More peaceful than I've felt in millennia," he rumbled softly, palming their stomach now swollen with transfluid

They tense and squirm before finally settling, snuggling back into his arms enjoying the warmth that radiates off his frame. "Mmm well work on the blocker tomorrow i wanna cuddle" they mumble to Ratchet.

TF NSFW Headcanons #3 - Ratchet

warnings: sub/bottom Ratchet + oral fixation + praise + dumbification + face sitting + body worship kink + manhandling + Ratchet is literally my wife + the love of my life right here<;33

a/n: ratchet's design when he came back from saving his boyfriend>>>

-> Frame Ratchet has a frame that attracted all sorts of mechs during his academy days. He's a boxy frame, a bit short but none the less attractive. He has a wide and heavy chassis and a wide midsection. His hips are wide and load-bearing, with thick powerful thighs to support them. I know I was praising Optimus' thighs in the last one but 100% Ratchet beats him in that department. He has a warmer frame than most mechs. Ratchet's berth partners love to push their helms onto his chassis, his midsection, his warm embrace, or his big thighs. They nuzzle into his frame while listening to his half-hearted grumbles, admiring the flush on the medic's face.

Ratchet's array seems to be average at first sight but don't let looks deceive you. Most of his berth partners get fooled by his standard valve, dark, plump lips with a pretty red node. But the moment someone slips their spike into Ratchet's valve, they had better prepared themselves or they might overload on the spot. Ratchet's valve clamps down like a vice once his partner bottoms out. His extra warm frame makes his valve run hot like lava, but it's only so much more pleasurable for the one spiking his. His greedy valve sucks in his partner's spike, unwilling to let go. While Ratchet moans lowly, his partner will be biting their own glossa trying to control themselves and to not start bucking into him like a wild mechanimal.

-> Oral Fixation Ratchet likes to suck things. Like, a lot. Something that will always get him in the mood is his partner rubbing a digit against his lip, and pushing into his intake slowly, slowly adding more as they watch Ratchet drool all over them. His optics glaze over, a fuzzy feeling filling up his processor. He's easily brought into a deep subspace as he noisily sucks on his partner's digits. The charming wrinkles on his faceplate soften as his body fully relaxes and leaves himself in his partner's care. While his glossa sloppily swirls around his partner's digits, his panel had since been retracted and his neglected valve is dripping wet. He's too far gone to even give his soaking pussy any attention.

-> Praise/Body Worship Ratchet would rather die than admit it, but he absolutely loves being praised and showered with affection. He may act annoyed when his partner sits him in their lap and begins caressing his body, but he can never keep up the act. Ratchet can't help but whimper as his partner's servos roam his chassis while the intake his on his throat cables leaving small dents on them, all the while they're murmuring sweet nothings into his audials. It's almost therapeutic for Ratchet. It just makes him feel so loved to have his partner run their servos all over his frame, dipping their digits into seams and pulling on bundles of wire that has his thighs trembling. Ratchet lets out small whines as his partner leaves sloppy kisses along his jaw, only for his noises to be swallowed up when his partner closes the distance between their faceplates. He just can't help but hope for the moment to never end.

-> Face-sitting With enough pestering, Ratchet will grant his partner's wish for him to sit on their face. He grumbles about how he's too old for this and how he's too heavy until his partner grabs him by the hips and pulls him to their intake. Ratchet whimpers as his valve is thoroughly eaten out, the mech underneath him lapping up all his juices. Ratchet's big thighs instinctively clamp down on his partner's helm, an embarrassing yelp leaving him. Yeah, maybe he slightly crushed the helm of the mech under him, but his partners know the risks. Anything is worth it to get a taste of Ratchet's valve. His partner will thrust their glossa into Ratchet's quivering hole and Ratchet will only be able to moan as his pussy is being ravaged, unable to tear himself away from the onslaught of pleasure he's receiving. He'll grind his hips into the intake he's riding, until he feels that familiar heat in his lower regions bloom. Even when Ratchet overloads with a loud cry, his partners stay glued to his pussy, lapping up all the juices from his valve. He'll protest weakly but will end up finding himself rocking his hips again, hoping to get another overload from the skilled glossa under him.

-> Dumbification This poor mech is so stressed out. During the war, he had to treat hundreds of thousands of mechs with gruesome injuries, and even after everything is "over", he just can't catch a break!. It's why one of Ratchet's favorite things for his partner to do is to fuck him dumb. It doesn't matter how his partner does it, with a false spike, a vibrator, he doesn't care. He just wants to be pounded so hard and deep, grinding on the ceiling of his valve and watching a slight bulge form, manhandling him into all sorts of positions and keep fucking him so stupid that he can't even create a coherent thought, let alone speak out loud. All that's filling Ratchet's processor is lust as he feels that wonderful spike just keeps slamming into his wrecked pussy until they overload in him once again, the transfluid in his hole barely having enough space to stay inside of him causing some of it to dribble out. He's slurring his words, making 0% sense as he's fucked silly. If you were to ask him what his own name was he wouldn't even begin to thin of an answer. All Ratchet can manage to think of with that fucked stupid processor of his is that he won't be walking for some time after that.

[uselessmicrowave]

I saw a post of yours a while ago and decided I want to request it. Tfp Ratchet cockwarming a bot!reader while they work.

“C'mon, Ratchet... Please...” you whine, sitting on his lap while he sits at his desk, just waiting as he does busywork with the synthen formula.

“You can wait.” he says dismissivly, a frown on his faceplates as he taps at the datapad. "You've made it farther before."

"But I don't want to make it as far today, I want an overload," you whine quietly. "please..."

Ratchet shakes his head no, cradling your helm into his neck cables in an effort to quiet you down. "Shh..."

You whine again, more quiet this time as you try to grind down on his spike, exterior node aching against his stomach paneling. You take a deep intake, breathing in his scent as if to calm yourself. You grip at his kibble, his spinal strut, his shoulders, anything, really. Anything to remind him that you need him now, and that you're not so happy with his stamina at the moment.

He'll give in to your clenches and whines and shakes eventually.

[cyberrose2001]

"Just relax... and let me taste you..."

NSFW UNDER CUT!! Minors DNI

okay i was severly debating on posting this but fuck it how could i deprive my audience, im not a monster

enjoy some synthen ratchet eating you out

(will most likely update this with different skin tones so watch out for that)

[moriarty-i-s-back]

“I don’t particularly like seeing you in pain, you know. I... I care about you,” he whispered in your ear. His other hand began to move up your thigh. “And it seems I caused you to neglect taking care of yourself this morning.”

You gulped and looked down at his hand on your thigh. It was wet from the ocean, but you swore you were catching fire from his touch alone. “Ratchet,” you breathed out. Your heart was beginning to pound beneath your chest.

He moved his mouth closer to your ear and nibbled your earlobe. “If an orgasm helps relieve the pain, then it seems as though I owe you one.”

[transformers-spike]

Since you were so graceful to deliver us that magnificent Optimus (and autobots) x Human in their heat cycle, another question arises. What are the autobots' thoughts on eating pussy? What about their styles?? Please and thank u

Good god, I’m going to assume this is general TFP pussy eating and nothing to do with the heatverse. For now I’ll stick to the main cast and add Wheeljack/Ultra Magnus/Smokescreen when I get a better feel for how I want to write them. (also fuck making gifs, thank you for existing, Tenor)

Back when he went by Orion Pax, he was as chaste as a lily. Not from lack of fuckability, oh no. His small frame at the time made him especially cute to onlookers, but it was nigh impossible to hang around him when he was too busy working as a clerk or researching Cybertron’s history in his downtime. There's certainly a possibility he ate at least (1) valve back on Cybertron. Whose? Who fucking knows. My bet would be on Megatronus, but he wouldn’t have horribly fumbled the bag if that was the case. Maybe cunnilingus could have saved their planet… Having, to an extent, merged his consciousness with the thirteen primes, he has gained their wisdom and become something akin to a demi-God by Cybertronian standards. Except with none of the praise, and the weight of the world on his shoulders. Anyway, let’s cease philosophizing about his nature as a Prime, what we’re looking for is how good he is at eating pussy with that extra knowledge. Answer: it depends on the receiver. Considering the size difference, he makes it work without catching your clit between his glossa’s mesh plating. He prefers supporting you in his massive servos, carefully wrapping his digits around your frame in case you start squirming too much and fall off. He applies slow languid licks between pauses, waiting to gauge your reaction in case he’s hurting you. It’s sweet of him, but please Optimus, you need to make your partner cum else they’ll die.

Ratchet has been alive for Primus knows how many slutty millenia. Of course he can eat valves. And if he can eat valves, he can eat human pussy just fine. The hard part is dragging him away from his workstation. Don’t get him wrong, he would love to bury his face between your legs, but he’s got things to do, nevermind a whole ass team to keep alive on top of manning the ground bridge and fixing whatever alien technical bullshittery Raf can’t help with (seeing as the little guy only takes care of the human technical bullshittery). He’s perpetually exhausted, and if Cybertronians had an equivalent to coffee, you’re sure he’d be downing it like a single father after losing everything in the divorce except the kids. So when he gets the chance to eat pussy, he takes his damn time with it, pressing his face against your groin for so long you think he’s fallen into recharge. When he gets to work, he’s savoring every inch of you, making a point to complain there isn’t enough energon to mass displace and taste you completely. The size difference is especially annoying to him, but he makes due nonetheless by slipping the tip of his glossa between your folds, pushing it as far as it can go without hurting you. His engine growls from desperate hunger as he grinds his spike against the ground, grunting and scoffing against your pussy as he has to contend with the smallest sample he’s ever received. Ratchet is going to kill Megatron.

Bulkhead is a complicated case. Yes, he’s tried valves. Any wrecker worth their weight in energon has eaten valves like no tomorrow. But the point is, when you look at his jaw, things get a bit complicated. An overbite in humans is mildly bothersome for a giver, but it gets even worse when you look at Cybertronian anatomy and realize that oh, he’s going to do some major jaw exercises to stick his glossa out properly and eat you out. Thank fuck you’re so small in this case, you have no idea much easier this makes his job. To be fair, his main worry is hurting you. Optimus is careful, yes, but Bulkhead has known destruction for the vast majority of his life, not only as a career, but as a way of life. So when he finds you naked in his servos, smiling up at him, his spike retracts into his panel from anxiety alone. If he so much as bruises you, he will shrivel up and offline. He can handle humans just fine, but during interface? He already has to take a breather before he tries anything in the Cybertronian equivalent of a panic attack. His cooling fans are screeching, and if he could sweat, he’d be causing a major flood in Nevada and all its neighboring states. In conclusion, yes, he can eat out. Not perfectly, but he puts in some valiant effort that’s sure to pay off sooner or later.

At first glance, you may exclaim “Wowzers! Bumblebee doesn’t have a mouth! How can he eat pussy without glossa or lips?” – well guess what! Take a vibrator and stick it between your legs. That’s Bumblebee right there. They should add him as a synonym for it in the dictionary. He may not be able to lick up your juices, but he can buzz incessantly against your groin at a near illegal setting until you come undone. He is so proud of himself. And for his own sake, let’s hope he never got to experience valves before he lost his oral equipment. He tries to be comforting, beeping words of encouragement that you absolutely do not understand but get the gist off anyways. Chances are, he’s either helping you balance on top of his face to get the full hitachi magic wand duct taped to the floor experience, or you’re both lying down while you’re cupped in his servos as he buzzes excitedly between your legs; equal parts cute and overwhelming. You feel bad for using him like this, but he beeps reassuringly and urges you to lie back in his servos and enjoy the ride. He’s such a hitachi toy it’s not even funny anymore. You start giving him setting levels which he eagerly follows like the boyscout he is, keeping the same vibration pace even as you start humping his face plate. You pray to Primus Raf isn’t looking for his guardian, else he’s going to overhear things you would rather die than explain.

Arcee is… way too good at eating out. On Cybertron, she could eat a valve like her life depended on it, sucking on the anterior node and wiggling her glossa inside of it well after her partners would overload, begging her to stop from overstimulation alone. Nowadays, she still has it. With her two-wheeler frame type, she can easily access a human pussy without any trouble, treating it like the cutest minicon valve she’s ever seen. She’s all rapid licks and wandering digits, stuffing you to the brim when she’s busy torturing your clit between her lips, then circling around it as she pushes her tongue between your folds. Arcee’s a fucking menace. She leaves you a crying hyperventilating mess as you plead with her to let you breathe. Yes, she’ll take your words into account and stop at some point. Key word: some. You get a break whenever she fancies. This, or you go into cardiac arrest and she has to deal with your metaphorical blood on her juice-soaked servos, all from eating pussy too good. No one should have that sort of power. But Arcee does, because she’s an unstoppable force. Prepare yourself from some light pillow talk after she takes mercy on you, stroking your cheek and leaning in for a kiss. You can taste yourself on her intake, and she wants you to contemplate the flavor as she wraps her arms around your squishy body in a protective hug, the blue glow of her optics dancing over your skin.

Masterlist

This is more just some more information of headcanons I have and how I like writing the bots. So I hope you enjoy it. This one's more on the differences and similarities between humans and Cybertronians.

Word count: 2.5k

Warning: mentions of reproduction, and exploration of body's. Valveplug.

__________

So this is just a continuation for Human effects. This one also delves into some more information on biological, cultural and different frames and how they interact with each other, humans and other organic Creatures. 

Biological Humans and Cybertronians are vastly different even with quite a few similarities. 

Sparklings and children 

There is a very big difference in the body function of Humans and Cybertronians. Size for one but also Organic DNA and CNA. There are many things which can Line up with the other species but also function very differently 

Such as. 

structure and organ comparison 

Plating - skin

Helm - head

Processor, brain module - brain 

Faceplate- face

Audio Receptors, Audials, Receptor orifices - ears 

Nasal ridge, enstril, olfactory sensors- nose

Optical ridge - eyebrows

Optics, visors  - eyes and glasses sometimes visors are used as optics

Intake- mouth, throat or a breath. 

Denta, denta plating- teeth 

Glossa- tongue 

Mandibles (insecticons) - jaw 

Vocalizer- voice box 

Chin or chin plating are the same 

Chestplate, chassis- chest and higher stomach (abs area) 

Fuel tanks- stomach. 

Backplate, back struts, binary system,  bipedalism - back and spine, spinal cord. 

Servos and digits - Hands and fingers 

Sounder plating - shoulder blades 

Pede - feet 

pump and Spark - heart and soul 

Energon lines - arrays veins. 

Vents - lungs, breath. 

Pelvic plate - pelvis

Aft, tailpipe, skid plate- butt

Interface panel - covered reproduction organs

Spike - penis 

Value - vagina 

Carrier chamber, Gestation chamber - womb

Helm and head

With the fact one is filled with circuitry, coding and wires and the other is filled with flesh, fluid and other organic matter. Humans' heads are covered in hair most times. And even those who aren't their head Is still rather soft and smooth. And the bots love playing with human hair and facial hair when they are allowed too. 

It also leads to humans giving the bots head scratches, and it's something so man you the bots had never thought of and they love it. They will lay their head in their human lap and just enjoy the gentle touches to their Finial, audials, and helm crest. It becomes. Causal thing of the humans using soft little microfiber cloths to clean out dust and dirt from the small crevices in the bots Plating. Head pats and scratches really becomes something that Cybertronians love alot and it makes a lot of humans consider the bots large cats.

Faceplate and Faces. 

One of the things which is very different between humans and Cybertronians is how they show affection to each other. Cybertronians do a thing called a helm hold. Where they each hold their partner's helm in their servos while looking into each other's optics, it's how they show how much they care, because they are focusing only on that one person. And it means alot more after the war, to focus all your attention on just one bots servos shows a lot of trust, affection and love for someone.  

While humans have Hugging, kissing. So the bots are rather confused the first time they are hugged, tensing up not wanting to hurt their human. And they nearly short circuit when the human kisses them it's more out of fear. 

“Do you know how dangerous that is! What if I crushed you!” The bot hisses in panic while looking at their lover. “not to mention the fact that is my Energon Intake! Do you know what energon can do to Humans!” It nearly sends the bot into meltdowns as they hold their lover's face staring into their eyes trying to show them how much they love and care for them. It would break their spark if they accidentally hurt them. 

“it's called a Kiss, I was kissing you” the human tries to explain, their hands cupping around their bots servos. 

“a kiss?” the bot inquired. “Yea I'm sorry if you didn't want it, it's just I thought we were in that part of our relationship” the human begins rambling out of anxiety thinking they had messed up. In the end they both settle for a small gesture in-between. Pressing their head and helm, together as they cradle the other. 

Eventually they will come around to accepting kisses but it is only for very special occasions. Because the bot will make sure that there isn't a trace of energon in their system for their partner's safety. Over time it becomes them pressing soft kisses to each other's noses. 

Skin and Plating 

These are all the parts which somewhat are similar to humans, but also work vastly different than the human body does. So with this listed here are many of the things that vary with the similarities. 

Plating and skin are vastly different due to one being metal and the other being flesh, it's one of the things a lot of the Cybertronians love is how soft Human skin is. They really enjoy just fondling their human companions, pulling their checks, and enjoying how their skin moves. How pliable, warm and squishy they are. Cybertronians finding out about human breasts really takes them by storm. 

“What are those?” the bot asks while pressing a finger to their breast feeling how soft and squishy they are. 

“breast, boobs, tits they have a lot of names” 

“What are they for?” The bot continues to just slowly play with them out of curiosity, not knowing what the human would need them for. 

“they are used for feeding babies, they fill with milk, it's not a constant thing and not everyone's do but they are for feeding babies.” the human tries to explain and it just leaves the bot shocked. 

“You're with Sparkling?” The bot asked as they began fussing over the human more, gently pressing their digits to the human's body more. 

“no, no I'm not pregnant!” They laugh out loud while rather embarrassed. “‘but wouldn't they deflate?” The bot shoots back as their digits begin needing the flesh which makes the humans sigh and lean into the touch. “human babe, don't have the same functions as you.” They tease softly.

 It ends up with one bot having their human lover back pressed to their Chassis. The bot's servos just cupped around their partners breast slowly massaging them as the human leans back just enjoying the feeling because it takes the weight off their back and the cool touch of the metal feels delightful against their skin. 

Heart and spark

The difference between a human heart and spark aren't that different at all. They both pump blood/energon to where it's needed, it's the life provider of the body. Each has a beat or pulse. And the said beat and pulse sounds different. A human's heart beat feels like a thump but to Cybertronians it's an echo. Each beat they can feel and see like A beating light. And they love how it feels laying against them, their spark will actually fall in tune With their heart beat as a way to calm the human.  While for humans a Cybertronians spark pulse feels like electricity dancing across their skin it's like the build up of static but it doesn't zap. The vibration of a spark is like energy building and releasing, the buzzing sound that just resonates through their body as they lay against their bot. 

olfactory sensors and nose

Unfortunately humans don't have the enhanced scent sensors that a lot of other species do, and Cybertronians have one for the most advanced ones, they don't just smell it but they can break down the chemical compound to its base and are able to tell humans emotions based on how they smell. It also leads to bots becoming rather touching with their lovers when they can smell their cycle. It also leads a lot of bots realising they have a breeding kink after being with a human, because the moment they can feel their partners change in hormones they are hovering. It becomes an even bigger thing when they smell the scent of a young spark, they feel the EM Field. 

carriers and pregnancy 

There is a major difference between human pregnancy and cybertronian pregnancy. Humans can only be born from reproduction.  a new spark can be formed in multiple ways. 

-Forged.  

-Cold construct. 

-split spark

- Sparked 

Forged new sparks are bots that are formed in hotspots across cybertron and on occasions sparklings can also be formed from these hot spots. 

Cold constructs are bots that have been made by others for a purpose and were originally classed as 2nd class citizens, miners or lower than other bots, 

Split Sparks made from splitting your spark into another form. It was very rare due to multiple laws being inplace against it. 

Sparklings were formed through spark merging with another and creating enough energy to form new lifeforms. A carrier would then have to host said spark in their Gestation chamber until the spark could grow its own protoform. Then from there they are moved into the carrier chamber where they learn off their carrier's coding, and also receive food, coding and personal information from their Sire via Transfluid. As sparklings are still not able to consume normal energon and it has to be processed down enough for the sparkling. (Similar to how humans breastfeed) from there once they are ready the sparkling will be ‘birthed’ and from their they will need to be carried in a spark chamber until they have fully developed but gives them time to learn the world around them but still have the safety of a parent to protect them. 

This leads the bots and humans to both be horrified at the differences of the others' reproduction. The bots are horrified over the fact a human's pelvis bone breaks just to birth a baby. But also the fact that humans can carry more than one child. They eventually watch a documentary over human birth; it makes a lot of bots short out and crash. 

Humans on the other hand are shocked over the time it takes for a bot to have a sparkling. 100 years is longer than a lot of humans ever live but it's how long it takes for the full process of a sparkling to be formed and born. That's without all the issues with CNA, temperature, spark energy, energon. A Lot of Cybertronian pregnancies don't make it to term due to these factors. 

So when by some chance a human gets pregnant by a Cybertronian it has the whole planet up in a tissy. Not just the fact of how genetically different they are but how it happened. The first human Cybertronian sparkling is a miracle watched by man and documented. And it turns out the human womb is actually the best possible hosting spot for the start of a sparkling, it's the perfect temperature, and it's not a temperature a lot of bots can keep their own frames. The human womb actually short cuts a lot of time over the birth Due to the sparkling Not needing to be shifted from one chamber to another. It comes down to being pregnant for 3 years. It's a long time for a human but it's decades Less than what it normally takes for a Cybertronian if they made it through the full progress. 

And when the sparkling is born it's discovered that the sparkling doesn't have any human traits, defects or appearance. Due to the human body mainly working as a host, the CNA and DNA don't mix when it comes to creating a sparkling but they work perfectly in sync When it comes to helping the sparkling grow. And it also turns out humans are able to sustain more than One sparkling. 

That also brings me to the function of spike and Valves. For Cybertronians spikes and Valves aren't how Sparklings are created, sparklings are created from two sparks merging together and creating enough energy for a sparkling but interface is needed to start the process of how they form. Sparkling needs Transfluid to begin and that is what Cybertronians use interfacing for outside of sharing memories, information and emotions. Most times Cybertronians interface for fun, feeling close, sharing information with a loved one, or to help feed a sparkling the necessary data, fluids and programming. 

so When a Cybertronian and human interface it has a lovely mix of a 50/ 50 chance of getting pregnant due to how the human and cybertronian heart and spark link in a frequency that is almost essential Spark merging. And a human doesn't even need to interface with a Cybertronian to get pregnant.

Here is a list of ways humans have gotten pregnant/ a bot has gotten pregnant. 

-interfacing 

-spark bonding 

-a human touching a bots spark. 

-having enough hated for another you get them pregnant by sheer Anger

- spark And heart syncing 

-A human being on their cycle will make a bot pregnant.

Megatron entered the medbay of the Lost Light, feeling unusual warmth and pressure in his chest. "Ratchet," he said gruffly to get the medic's attention. "Something is...off. I feel as if I have consumed fool's energon again, but I know that is not the case." 

He looked down at the medic, his optics betraying slight concern beneath his usual stern demeanour. "Examine me and determine what ails me. I need to be at full function." His pride did not allow him to admit weakness easily, but he trusted Ratchet's skills. 

Ratchet nodded to First Aid and They as they stood ready to assist. He turned back to Megatron with a scrutinising gaze.

"When did you first notice the symptoms? Any other anomalies in your systems?" he asked gruffly, scanning the Decepticon warlord from head to foot with a diagnostic tool. The scans showed unusual activity in Megatron's Gestation chamber.

"Hmm...it appears your spark is pulsing more rapidly than normal. And the pressure you described suggests a buildup of energon flow." Ratchet paused, analysing the data. "This could indicate...no, it's not possible. Or is it...?" He leaned in closer, inspecting Megatron with keen optics.

"We'll need a more detailed scan. Over here, lay back - this won't hurt but may feel peculiar. First Aid, fire up the resonator. Ambulon you're in charge of monitoring vitals."

"What's wrong, ratchet he was fine this morning?" The human asked in concern. 

Megatron lay back on the medical berth as directed, his massive frame dwarfing its size. his expression softened ever so slightly. As the detailed spark scan began, Ratchet's optics widened in surprise. "By the Allspark...it can't be..." He motioned First Aid "Look here. What do you see?"

First Aid peered at the monitor in amazement. "Two distinct spark pulses...but how is that possible?" Ratchet glanced over at Megatron, then back at the others. "It would seem Megatron himself is carrying sparkling. The increased energon flow and pressure were signs of protoform development beginning."

He chuckled wryly. "Well Megatron, it seems that fool's energon was not to blame after all. Congratulations...you're going to be a creator." Megatron's optics widened in disbelief at Ratchet's announcement. Carrying sparkling? It made no sense as far as he knew, spark merging could only occur between cybertronians and he had only been intimate with a human. 

He sat up abruptly, almost knocking First Aid over, and glared down at Ratchet. "Explain yourself, medic! How is this possible? The human and I have been intimate but they clearly lack our means of conception." Ratchet held up a calming hand. "Peace, Megatron. I have a theory,"

[uselessmicrowave]

i really wanna suck TFP Ratchets dick HGGGGGHH i want to edge him with my tongue for hours until i fall asleep with his cock still in my mouth please GOD it’s all I want in life

“You have to- mmh- to finish me off sometime, kid.” Ratchet stutters. You hum sleepily, running your tongue along the bottom of his spike, gently teasing the slit at the top. It hadn’t registered in your mind yet, but you’ve been mouthing at his spike for hours, it’s well into the night now.

It could be the next day for all you care, as long as you get to keep him in your mouth. You look up at him, eyes half mast and cheeks dusted in a cute blush. He looks a bit frustrated, but he’s still blushing hard. His intake is slightly open, heavily venting from your actions. You want to tell him how pretty you find him to be in his flustered state, but you can’t bring yourself to lift your head or take his spike out of your mouth. He loves you, but he wishes you would just make him overload.

You close your eyes, now smiling around him, gently sucking on his spike. He bites his derma, whining quietly and clenching his servos around the sheets.

“Please, Y/n.” He whispers, trying to grind his hips up into your warm mouth. You squeeze the wiring on his thigh, making him stop. He whines again, knowing that you won’t stop till you fall asleep.

AYYYYYY! Do you remember that request I sent a while ago of the Ratchet x Fem reader? Ya know where Ratch gets to frag the reader to blow off some steam?

Reader is Cybertrionan btw if that's okay!

Stress Relief

TFP Ratchet x fem! cybertronian! reader

whoaaa you can tell I started this months ago eheh… apologies for the long wait I hope y’all can forgive me 👉🏼👈🏼

“I’ve been waiting all day for this,” Ratchet huffs, tossing you off his shoulder and onto the berth, “Too fraggin’ long, if you ask me.”

You refrain from making a smart aft comment about how he had actually been waiting all week, but you’re too preoccupied with how he’s pulling your hips closer to the edge of the berth.

It’s always the same with Ratchet. He would have a busy week (aka working his processor to near power down), barely seeing him all day, then apologise profusely for coming to berth late. And by that time, you’d already be in stasis, waking up to your frame gently tucked into his while he spoons you. It annoyed you, having to wait days; hell, even weeks sometimes before Ratchet had a chance to lay a digit on you.

But you’ve quickly learned throughout your relationship that the longer Ratchet goes without interface, the harder he fucks.

His digits are pressing into the seams of your hip plating, calculated and efficient with aeons of experience against your frame. A low moan escapes your throat as you feel your modesty panel easily click open. You’re already dripping wet at the anticipation, and it hasn’t gone unnoticed by Ratchet.

“Then why don’t you frag me then, hm?”

“Oh, I intend to,” Ratchet kneels on the ground, two servos keeping your thighs spread as his hot breath teases your valve, “Only if you can suppress your smart commentary and let me indulge in you first.”

You crane your neck as you watch his dermas latch onto your exterior node and subsequently throw it back against the berth with a clang as he starts sucking and flicking against your node. It’s electric and oh so sensitive as he scrapes it against his dentae.

“Oh, Ratchet.” A filthy mewl escapes your mouth, bringing a servo to his helm when he starts drawing slow circles with his glossa, “Please, I can’t- I need-“

“You need what, exactly?” Ratchet lifts his helm from your heat, and primus, your fluid already coats the lower half of his face in a pink sheen.

“Need your spike- ahhn.”

“What do you want me to do with my spike?” A harsh kiss to your abused node sends shivers up your back strut, which turns into clamping your thighs around his helm as he plunges his glossa into you.

“F-Frag… do you need to ask… nghh… so many questions?”

“So impatient, aren’t you?” Ratchet rolls his optics with a groan, either out of frustration for your impatience to hasten things or his desperate need to shove you face-first into the berth, “Turn around, let me see that pretty aft of yours, sweetspark.”

You obey his command, pedes firmly planted on the ground as you bend over the berth. A weak whine vibrates the bed as Ratchet presses your helm into the silky sheets, another servo pushing his engorged spike against your cunt.

“Now be a good femme and stay still for me,” He groans, sheathing his entire spike into you before pressing his body weight against your back, “my little stress toy…”
