[cyberrose2001]

Heyo! Can I request some stress sex with Op, fem reader and Ratchet? The two work so hard and maybe some.joking around when mentioning the readers name, the two stressed bots snap, and reader ends up railed into?

TFP Optimus x human!Reader x Ratchet

Hayy thank you for requesting! I've kind of just jumped right into the good stuff since I wasn't entirely sure what you implied with the joking around. Either way, I hope you enjoy!

"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."

__________

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,"

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.

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.

“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.”

So what about, Cybertronians react to perfume in the way humans react to Sex pollen hehehe. I love the idea of human perfume mix with skin contact makes an almost intoxicating scent and sends Cybertronians feral when they get a hint of it. They love how it makes humans skin taste, and it over rides their interface systems.

So enjoy.

_____________

The human moves around Ratchet's medical lab looking at different vials and flasks their eyes flickering over the difference Liquids. " Hey ratchet what are all of these different vials?" They call out to the medic. Ratchet looked up from his work when he heard the human call out to him. He put down the datapad he was looking over and walked over to where the human was examining the various vials on the shelves.

"Those are different medical compounds and chemicals I use in treatments and repairs," Ratchet explained. "The colourful ones contain powerful medications and sedatives. The clear ones hold things like bonding agents or nanite solutions. Others are a mix of experimental solutions" 

He pointed to a vial with a swirling pink and purple liquid. "That one is a broad-spectrum energon healing compound I developed. It speeds cellular repair and regeneration, within Cybertronian functions." His optical ridges furrowed as he watched the human carefully look over each vial. 

"You know better than to touch anything in here, less you break something and contaminate yourself with something i can't fix" Ratchet said sternly. "Some of this equipment and chemicals could seriously harm an organic being like yourself." Despite his gruff tone, his words held more care than scolding. Biology was complex, and humans were so small and fragile compared to Cybertronians. He hoped his favourite little patient and helping hand was being careful not to endanger themselves.

"It's just fascinating is all, kinda reminds me of a mediaeval apothecary" they chuckle. "Do you ever just take samples for fun, like when you're out and about on planets?" They ask, they were always curious over what things ratchet tended to keep.

Ratchet huffed a small laugh at the comparison to a mediaeval apothecary. "Fascinating perhaps, but also dangerous if mishandled," he remarked.

He considered the human's question for a moment. While most of his samples were acquired for medical necessity, he couldn't deny a certain curiosity about other life forms and ecosystems. 

"On occasion I have collected specimens from planets we've visited, simply for observational study," Ratchet admitted.  He walked over to retrieve a data pad containing photos and analyses of plant samples from their recent away missions. "Here, let me show you some I recorded on our last stop." Ratchet enlarged the images for the human to easily see. "This radiation-resistant lichen seems to secrete a natural antifreeze. And these fungi act as natural air filters in their toxic environment." The medic's optics glinted with interest as he discussed his findings. Perhaps exploration held some appeal, even for a skeptic like himself.

They stand close to Ratchet looking over different specimens, “some of these plants look like they would make really nice perfumes'' they mumble while flicking through the different photos reading the small information bubbles around them. As the human stood near Ratchet examining the data on his specimens, something about their scent suddenly registered in his olfactory sensors. An overly sweet aroma was emanating strongly from their skin, but it was clearly not the normal scent of an unadulterated human.“perfume?forgive me, I'm not accustomed to what that is?” he asked with a raised optical ridge

Their eyes flicker to Ratchet. “It's like scented alcohol or oil we put on our skin, most times it alters our scent. We humans happen to have a big fascination with them, and have millions of different perfumes.” they explain before tilting their head in slight amusement. “I'm surprised Cybertronians don't have something similar” they reply. 

“once millennia's back cybertron did try making things like that, but due to our metallic body's it doesn't stay on us, or it tented to cause rust spots from the ones they did try and make” Ratchet explained, sensors flared as he analysed the unfamiliar composition, immediately detecting unusual chemical traces that seemed to send strange pulses through his neurocircuitry. The smell was strangely enticing yet worryingly off-kilter at the same time. He tried venting deeply to clear his nasal chamber but the scent only grew stronger. 

"What in the Allspark..." the medic muttered, not meaning for the human to hear. His optics dimmed slightly as redundant calibrations ran, trying to make sense of why the scent was affecting his processor. Ratchet crouched down and focused his sharp gaze on the human in concern. They smile up at him offering for him to examine. 

"By my scanner  it seems as if you've been contaminated with something. Are you positive these ‘perfumes’ are safe? I need to analyse your system for potential toxins." He asked while trying to figure out why the scent was having such an effect on him, it was as if his processor had thrown care to the wind. 

They let out a laugh as his optics try analysing, he moves closer taking another inhale of their scent "haha yes Ratchet, it isn't harmful, humans have been using it for hundreds of years" they state. “Ratchet are you alright?” They ask while cupping his face. 

Ratchet's sensors were in disarray as the potent scent overwhelmed his circuits. He vented heavily again, coolant failing to properly flush the heated energon now racing through his fuel lines. His optics flickered with minor instability as calibration errors cropped up across multiple systems.

Though lacking his usual gruffness. Ratchet leaned in closer, trying to pinpoint the source, but only succeeded in inhaling more of the intoxicating aroma. A rumble rose in his chassis against his better judgement. “ your scent...", he struggled to find words between fragmented logic protocols. "It's affecting my sensor net. Overloading my functions. I need to...run a full examination. Determine why this perfume is making your scent overwhelming..." 

His field pulsed with uncharacteristic confusion and static electricity. Ratchet knew he should contact someone for assistance, but found himself unable to call out in his muddled state. The human's safety was his top concern, yet he feared touching them in this condition. Some natural, impossible chemistry was at play here, and the medic had no control over his compromised systems.

As gently as his shaking grip allowed, Ratchet grasped the human in his large palm to properly scan them from close range. His detailed medical scanners searched every inch, They gasp as Ratchet glossa meets their throat, fingers shootout to grip the side of his faceplate. 

A throttled moan escaped his vocalizer against his will. That light touch from their hands nearly shorted out his already fritzing systems. vents plume in hot exhaust. His interface panel felt too hot and tight , barely clinging to integrity protocols as the pleasure centres of his processor went haywire. 

“your scent...overloading my sensory net...cannot...resist...” Ratchet calls out through groans,his grip unconsciously tightened around the small organic in his hand. His free hand scrambled for purchase on the table, denting the metal. Something primal and powerful part of him was unravelling his mental restraints, and no calibration or forced shutdown seemed able to stop it.

Their eyes go wide. "Ratchet! Are you alright do in need to get a Perceptor or first aid?" They ask as the medic leans down into their shoulder, denta nipping at the skin as his digits try removing their shirt as quickly as he physically can. They yelp as he pulls them back together with him, his lips work along their smaller frame desperate to taste the sweet flavour and scent that had taken to their skin. capturing them against his heaving chassis. His optics blazed with static and uncontrolled charge.

"No...don't leave," Ratchet growled through clenched denta. Every fibre of his being screamed for more. His panel snapping open with an echoing click, massively engorged cables twitching in the open. Coolant and lubricant poured from his interface array, drenching the human involuntarily as he grinding against them, bright glowing pink stains their pants and paints their skin in his transfluid. 

His hands trembled, barely able to restrain their desire to claim the tiny body before him. Rational thought was impossible under the onslaught of chemical signals frying his cognition. Ratchet bucked erratically against them, whole body illuminated by dancing electricity. 

"Need you... interface protocols are in-gauged, can't fight it...please,!" he pants to the human as his spike presses against their back. Blunt node swelled monstrously at its tip.

Their back arches into each grind of Ratchet's spike. “Ratchet!” They whine out. 

Their soft noises egg ratchet on, his servos move quickly, trying to discard the pants sticking to their form, he hisses out in annoyance before finally getting them off their legs, throwing them across the medical room. Twisting them around so he can see thier eyes. 

Ratchet growls eagerly spike swiftly sliding between their thighs and against their stomach. His spike is already dripping with lubricant. As he ruts against them. Each inhale of their scent has him spiralling more. 

"Is this what you want, sweetspark? My spike filling you up?" His voice is rough with lust. Gently spreading their legs wider. Watching the bright pink stick to their legs "Primus... I bet you feel amazing." 

He moves slowly pressing his spike against them, tormenting as he presses into them inch by inch. Needy moans leave their lips, hands clinging to him desperately as they roll their hips. “Ratchet!” They cry out. 

 Their stomach bulges from Ratchet's spike, the bright pink splatter across their skin nearly has ratchet overloading from the mere sensation, not to mention the intoxicating scent of their skin. Ratchet groans deeply at the sight of his spike bulging their abdomen, his engines rumbling with feral satisfaction. One hand strokes almost reverently over the taut swell.

"So stunning like this... stretched wide around me, primus so small and tight”

Slowly he draws his hips back, then thrusts forward, grinding deeply into them. setting a steady pace, rockin into the slick heat enveloping his spike. Ducking his head, he captures their shoulder between his denta, glossa flicking against the sensitive skin as he tries to lap the perfume from their skin.

Ratchet growls deeply, thrusting harder at the way they clench around his spike. The table creaks and trembles under the force of his movements but he can't bring himself to slow down. 

"Yes, just like that," he rasps. "Keep that sweet valve squeezing me. Feels so good..."

captures their cries in a heated kiss. "Want you to overload for me," Ratchet purrs. "Let me feel you come undone around my spike, sweetspark..."

His engines are roaring furiously now, spike swelling and throbbing powerfully inside their smaller body. Ratchet groans deeply as they clench around him again, the feeling of that slick heat clenching and rippling around his spike is incredible. 

"That's it love, overload for me... you feel exquisite. So good" 

The sensations quickly become too much for his own systems to bear,the feeling, scent and the pure primal heat running through his system hits hard. With a staticky shout of Julian's name, he buries himself to the hilt and overloads powerfully. His transfluid gushes hot and thick, pumping deep into their smaller form. 

His engines vent heavily as he leans over them, face pressed into their shoulder, a deep guttural moan leaves him, Shuddering with aftershocks. When he finally leans stack to take in their exhaust and truly used form their lungs desperately inhale and exhale drawing in air as if it was their life line. 

Bright pink transfluid pudding around them as Ratchet's systems finally subsided. His optics flicker on them. “ Are you alright?” he asked softly, his human companion replied with a soft whine and nod. “ Remind me not to wear my perfume out in public” the call out in shuttered words. It makes ratchet chuckle as he leans back down to them. “a wise decision”

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.

[cybertronian-cupid]

oooh, um, is it weird to ask for some cockwarming headcannons? 👉👈 with the best docbot around? (cant get enough of the Ratty tat tat) i think i may leave the continuity up to you if that’s chill

Not weird at all anon! We decided to go with tfp and the headcanons include him keeping a cock warm as well!💥~Gregoria🏩

............................. ....................... ............................

Reader being a cockwarmer:

He starts out doing it at night during recharge

He was unsure about it when his s/o brought it up in an attempt to seduce him into fucking and then recharging more often.

Back in his younger days this wouldn't have been a thing. But he’s older now and he ends up enjoying it more than he expected.

He eventually starts using it as a form of foreplay.

He slides in with some difficulty, but the longer s/o sits the bigger his spike feels

Is it just because they're getting impatient? All they can really do is clench, and try to distract him from work.

He'll hold back as much as he can because he wants them to be more desperate than he is.

He gets a bit twitchy, but a grumbled “sit still” and a distracted pat on their head usually does the trick.

If he’s mass displaced he might drum his fingers on their thigh.

If he’s the cockwarmer:

His valve is not really used to the stretch since he doesn’t use it often. Spike overload is faster, less messy and in general much more convenient.

But he can and will indulge his partner from time to time.

He is surprisingly loud when his s/o slides in and is incredibly grateful for the weight displacement chip. This is a treat for both him and his s/o and he is not getting off that dick anytime soon.

He usually does this on an off day, when both of them know they can take it slow.

He’s squirmy and teasing, and takes special delight in ordering his partner to keep their hands on his thighs.

[zenniet]

Hello! Can I have TFP Ratchet tied up with a human fem s/o lovingly teasing him, complimenting him, telling him how much they love him, and edging him before they let him overload?

You’re not entirely sure on if he could actually break the ropes if he wanted to, but one way or another, he’s keeping still for you. Servos tied behind his back and his thighs spread as he kneels. His spike twitches and bobs with his sparkpulse and the energon rushing through him.

“Such a nice spike,” You say, your hand barely ghosting over it, “Feels so good in me when I ride it.”

His vents hitch. He can’t say anything, naturally, since you gagged him as well. You know that if you hadn’t, he’d be trying to object to everything you say. You’ve already been working him up for the past twenty minutes, letting him teeter on the edge of his overload. You’ve gotten awfully good at telling when he’s close just by his body, the way he shivers, when his engine purrs, you know when to back off.

“And it belongs to such a nice mech, too.” Your hand closes around his member and you stroke it. “So strong, attractive, and the kindest person I know. Can you feel my eyes on you when you walk around the base? I sure hope so, I hope you know how much I just can’t keep my eyes off you.” You lean down and press a kiss to the head of his spike. He twitches, but keeps himself still and his legs spread.

“I love you so much, Ratchet.” You look up at him. His engine stalls then roars at the sight of you, eyes full of adoration and your hand on his erect spike. His spike throbs in your hand and you pick up the pace of your movements. Prefluid coats your fingers and slicks your strokes, his vocalizer giving you a low moan.

“You’re close, I know, I can feel it.” You kiss his spike again. “You wanna overload? Get me all messy? Mark me as yours? Because I am yours, just as much as you’re mine.” Your pace only gets quicker. His hips start to rock, thrusting into your hand, unable to stop himself at the prospect at getting to get you filthy with his transfluid.

“Overload for me.”

And he does. Hot, heavy spurts of transfluid fall across your chest and hand and face as he moans, thrusting into your still moving hand. His engine gives a whine and a growl and his vents stutter, optics squeezing shut as he rides out that pleasure.

When he finally manages to come down from that high and open up his optics, just the sight of you covered in his fluid is enough to have his spike stiffening again with renewed interest. Not that you mind that, though, you still have to get your fill.

[bots-and-cons]

your blog is great and the most interesting one I know on this site! ❤❤❤ Ratchet/Ultra Magnus/ Megatron notice that their o/c is a sadomasochist

I don't really do NSFW so this isn’t really explicit. I guess this can be human or bot reader and I’d say mass displacement is a thing (aka Megs, Ratch and Magnus can change their size to fit better with their human s/o). Thank you, I’m glad you find my blog interesting.

~Megatron~

•So Megatron is definitely a sadist, and he likes inflicting pain on others, be it in the berth or just plain torture for intel

•He really enjoys the fact that you’re a masochist, but he doesn’t really like the sadist part, unless it’s someone other than him you’re inflicting pain on

•He likes to bite so hard he draws blood and there are always scratches on your back after a good fragging

•He is definitely up for trying all kind of stuff as long as he is the dominant one

~Ratchet~

•He has an idea what sadomasochism is but you’re definitely gonna have to explain it to him

•His face is priceless and you can’t help but laugh when you’re done with your explanation

•Cybertronians have a different word for it so when you explain he has a bit of an “Aaa” moment

•He hates hurting you, but I think he wouldn’t be opposed to you being a bit sadistic towards him in the berth, just something light and not anything too hardcore

•Ratchet is very gentle in the berth and it’s very soft loving if that makes sense

~Ultra Magnus~

•He is so authoritarian (idk if that’s the right word) normally that in the berth he is very much a sub and a bit of a masochist as well, but he can be the dom too if you want him to be

•Anyway he needs to be punished, for being a bad mech ;)

•Or maybe he’ll punish you

Ratchet masterlist

Rut cycle masterlist

______________

"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.

Could I get a headcanon for Ratchet and his human s/o trying to find ways to have some uhh.. adult fun, while navigating around their huge size difference?

Sorry this took so long! Wasn’t sure how adult you wanted it so, I kept it real soft. If you want a little more N///S///F///W Send in another request and I’ll def write more! - Mod Shy

                                    Kiddos! Keep scrooling! 

When you both agreed to try it out, both of you were nervous af

Ratchet did research on human anatomy

He was the one that was the most concern

In the berth, it’s small trust touches in places the other hasn’t explored. 

Ratchet likes to feel the smooth human skin

Mostly to see what you like and how you react

His attention is on you!

Kissing your small body and running his digits down your skin

Shivering and wiggling make him feel like he’s doing it right

Prodding your lower parts to hear you is his intent

There is no being quiet with him, it lets him know you’re okay and like it

If you try to focus on him, he’ll deny

“I just want to make you happy.”

You have to convince him to let you try some stuff

When he finally let’s you, you can feel his engines rumble under your hands

Just the slightest touch from you, turns him into putty

If you press onto a sensitive spot, you can hear a soft sigh and a smile grow on his face.

If you start stroking and plucking at the wires, he’ll turn into a mess. 

The venting starts and his systems starts heating. 

He’s just very sensitive from your touches

Switching back to you, he’ll start to touch you down below

Thanks to research from before, he knows how to please you

He loves seeing you squirm and beg for him to continue

The small vibrations going through him can be felt and it helps enlighten the experience

After everything, he’s mumble in your ear softly how much he loves you

Makes sure your comfy before sleeping

He’ll stay by your side, making sure you’re okay

He definitely plans to find other ways to please you

Mass displacement?? 

Definitely will try that!
