#knockout headcanons

A = Aftercare (what they’re like after sex)

You. Will. Shower. After.

As soon as it’s over you can bet he’s immediately going to go wash and if you want him to consider ever touching you again, you will too.

Otherwise, it depends on how much you’ve got him wrapped around your finger yet. Early on you can bet he’s stoking his own ego while also shooing you away like a stray dog.

“Yes, yes. I know I just blew your mind and ruined you for anyone else, but if you don’t mind, I have work to do. Don’t give me that face I know you’ll be crawling back soon enough. If I’m bored, I might just humor you again, pet.”

If you have managed to wriggle under his plating after enough time, you’ll get to experience his version of doting I’m sure. Hidden under the gloating will be a softness and want to have you near.

“I knew you’d be perfect for me when I first saw you. I especially loved the noises you made for me, pet, the kind only an expert such as myself can draw. Come, I’ll even let you buff up all the grubby finger marks you left.”

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

His: he’d obviously say ‘everything’ but if pushed to choose he loves the curves of his waist and hips. He knows how to move that thang and boy does he know it. Of course he can’t forget the buffed paint job he spends hours perfecting.

Yours: this sounds weird but he would love your inner mechanisms. Holding you around your waist just to feel your rib cage expanding and contracting with every breath or your heart fluttering from within. Holding a servo to your wrist while he bends and moves your delicate hand just to feel those tiny thin bones twist and move under layers of skin and fat. Tracing the lines of your veins. So alien and fragile to him.

C = Cum (anything to do with cum, basically)

When using his spike, he won’t release as much as other mechs. His valve is what he makes the most mess with, even when not using it.

You will be painted with thick steaks of that glowing blue fluid as he pulls out, wondering why there wasn’t more, before looking down and seeing the puddle leaking from his valve under him. Don’t point it out. He will sulk.

D = Dirty secret (pretty self explanatory, a dirty secret of theirs)

Hypothetically, he’d love to just open you up. To touch and feel your insides working and moving like the internals an alien machine. To hold your heart and watch your lungs inflate then deflate with every viral breath. To be the only one to lay eyes on this sacred part of you. There’s something so fascinating about it to him and the thought of it has definitely haunted his dreams and fuelled some lonely nights fisting his spike.

E = Experience (how experienced are they? do they know what they’re doing?)

This bot fucks. He has fucked. He is fucking. he’ll fuck again. Need I say more?

F = Favorite position (this goes without saying)

Loves holding you as you lean back, eyes rolled, riding him. Or at the edge of his desk, legs wrapped around that slutty waist of his.

Anything where he feels in control while not having to put in the effort because that’s your job :)

G = Goofy (are they more serious in the moment? are they humorous? etc.)

I could see someone goofing around would make him sulk. He’s supposed to be blowing your mind and ruining you for anyone else and his ego would feel bruised if you’re not reduced to a whimpering mess.

On his end, you can bet he’s going to be purring the most filthy shit to you and laughing at your cute attempts to respond.

H = Height (do they prefer to play with you mass shifted or at their natural size)

Both for their owns boons. Enjoys the intimacy and additional dexterity of playing with you while closer to your own height but loves occasionally making you grind yourself against his spike at full size. It’s a reminder of you of how small and alien you are compared to anyone else he’s experienced.

I = Intimacy (how are they during the moment? the romantic aspect)

Without time and trust, expect him to be clinical and detached. It would be easy to mistake his taunting and degradation as genuine disgust and mocking. With time, however, you’d start to recognise the fascination and awe in his face as you take him so well. He’d begin littering you with just as much praise as mocking. Underneath it all, he would be loyal and obsessive. Needs to make sure to remind you regularly about how much you need him, how good he makes you feel, how you were made to please him, and him only.

J = Jack off (masturbation headcanon)

Knockout always feels ashamed to masturbate. Not because of any other reason than he feels he shouldn’t have to. Why isn’t someone doing this for him? I mean look at him. He’d always do it in the shower. Less mess and it’s usually followed by some self care (buffing his paint and watching a movie/car videos)

K = Kink (one or more of their kinks)

- It goes without saying, he has a medical kink. You’re alien to him and there’s just something so fascinating about exploring you inside and out and pushing your limits. You don’t want to know how many ‘medical journals’ he’s published with his findings.

- Stuffing. Pushing your holes to their limits with a smug, fascinated smirk. If you have a Vagina, he’d have a fascination with posterior fornix play/training. Depraved thoughts about how much he could stretch you out without tearing you.

- Public play. He’d love having you in his alt and ruining you while speeding down the road or even at drive in movies. His windows are tinted enough nobody can see you riding his shift stick but he loves how shy and humiliated it makes you. Would absolutely threaten to roll down the windows if you aren’t being good.

L = Location (favorite places to do the do)

A) his medbay. So many toys and tools at his disposal and that’s where all his best research takes place. It’s boring but eh, it’s his safe place and where he’s the boss.

B) at his street races. You’re either bound in the drivers seat, toys stuffed in every orifice or, as mentioned, around his shift stick. Loves to make you go play driver and greet the other racers after he’s won so you better hope you’ve finished by the time his door is swinging open.

“Nicely done. Now get your jacket on and show these guys the face of a real winner.”

Loves watching your flushed and tear stained face as you awkwardly shake hands and take compliments from the other racers and trying to (badly) answer their questions about your driving techniques and car mods.

M = Motivation (what turns them on, gets them going)

- Compliments and neediness. Loves someone with good taste, of course.

- When you’re dolled up. That can be a risky outfit exposing your soft skin as much as tight leather racing gear

N = No (something they wouldn’t do, turn offs)

Don’t degrade him. His ego is delicate. Treat him like the king he is.

Also won’t ever put you in real danger. Takes pride is keeping you satisfied and safe because nobody else could, of course.

O = Oral (preference in giving or receiving, skill, etc.)

Likes both. There’s something so delightful in watching you gag and drool around him, jaw painfully stretched to fit him. Will purr encouragements and mock you the whole time from how much prettier you are with your mouth doing something useful for a change to how your dribbling saliva is disgusting and messy. Don’t worry, his spike is throbbing at the sight of it leaking around him.

Teasing and cruel when giving. Knows exactly how to keep bringing you to the edge without giving you release as you feel him chuckling against you.

P = Pace (are they fast and rough? slow and sensual? etc.)

It always starts painfully slow. Watching your every expression as he slowly stretches you out then leaves you empty again. Likes to watch you fluttering and clenching around the empty space he’s left inside of you. By the end, you can expect him to laze back and tell you if you want to cum, then you have the stage. Lets you ride against him as hard and fast as you want until you’ve both cum.

Q = Quickie (their opinions on quickies, how often, etc.)

Likes to take his time. It’s a game to him to tease you and bring you to your limit.

If you want a quicky, expect to deal with rolling eyes. You’ll be doing the work.

R = Risk (are they game to experiment? do they take risks? etc.)

Will absolutely experiment on you in every literal sense of the word. With enough time spent together, there’s little you won’t have tried. His favourite research is finding what does and doesn’t make you tick. The rule to this though is that he needs to feel in charge of it. Even your ideas must somehow have been his. Again, as said above, if he’s doing something, the risk has been calculated. Even if his idea of safe percentages is different to yours, he’s adamant about whatever he does that he did the research, and with his skills and knowledge you were completely safe.

S = Stamina (how many rounds can they go for? how long do they last?)

Certified edging king. Knows every trick and tactic to delay both of your releases long enough to leave you exhausted and Bambi legged after hours of play.

T = Toys (do they own toys? do they use them? on a partner or themselves?)

Yes. He owns as many ‘mundane’ toys to niche kink items items no same person would consider to be sex aids and he will use them all on you.

Hismiths, Sybians, dildos, eggs, clamps, gags, spreaders. You name it knockout is giving you a look before pulling it out without even needing to look. Similarly, you can expect him to lay out things like speculums, syringes filled with who knows what (don’t worry you’re about to find out), an exam table complete with stirrups, and scalpels like they obviously belong in the collection.

U = Unfair (how much they like to tease)

Mean. Rude. Evil. He’ll do it all with a smile too.

Loves watching you struggle to stand on shaky legs after. That’s ok. He’ll carry you to the shower.

V = Volume (how loud they are, what sounds they make, etc.)

You can’t tell me this boy doesn’t purr and whimper. You know you’ve won when his smug comments and teasing falls to those.

W = Wild card (a random headcanon for the character)

Once while pounding into you asked you what your favourite thing about him is. Expected you to say his spike or his glossa or his purring voice but you smiled up at him and without hesitation answered “everything. You’re my favourite person.” He rolled his eyes at you but after, he cried about it in the shower, spark throbbing.

X = X-ray (let’s see what’s going on under those clothes modesty plates)

I like to imagine his spike is average size for a cybertronian. What sets it apart is that it’s pretty just like him. More biolights than average adorning the length and a dainty curl to it.

Y = Yearning (how high is their sex drive?)

He is always ready and eager. Initially, he couldn’t ever see himself getting tied down with one person. Always thought that being able to find endless people who wanted him would bring him worth and confidence but discovered that finding someone who will always come back and choose him again and again is what made him feel valued instead.

Having a partner doesn’t diminish his drive through. Now that’s all on you. Good luck.

Z = Zzz (how quickly they fall asleep afterwards)

Starscream

-You've picked up a lot of Cybertronian swear words thanks to all the talking he does to himself. He is surprised when he hears you use them, but then offers to teach you even more of the language.

-If you stim, he might stim as well (but only when he's alone with you). Moves his wings, and bounces his heels, messing with all the little spiny parts of his frame. It's a self-soothing stress reliever he definitely needs.

-He may act like any questions you have are annoying, but secretly he's glad to answer them. He missed home more than he would ever admit, and it's nice to pass those memories down to someone who seems to genuinely care.

-If he's going to supply you with information about your interests, you can expect to listen to his long rants from time to time. It's only fair, right?

-If there's anyone on board (cough, Megatron) who might give you a hard time for asking questions or anything at all that you do, expect him to wordlessly sit with you afterward.

After your safe return, Knockout basically put you on lockdown in his lab. He gave you everything you wanted in exchange for a promise that you'd never go near the dragon again.

"I was worried about you."

"I'm sorry, I didn't know he wouldn't let me go."

He watches your favorite movie with you while you buff his finish due to the nonexistent scratches he claims Predaking gave him.

Breakdown

He...tried. He would fight Predaking, but the second he dove for you, the dragon practically threw him off the ship. Knockout had to pull him off the ledge.

After several rounds of shouting at Predaking (he didn't even roar back), he started tossing vehicons at him. Of course, he aimed them away from you, so they mostly just thudded whole yards away from Predaking.

"I'm sorry, nothing I'm doing is working right!"

"It's okay, I think he just wants cuddles!"

"Sweetheart, nothing with those claws is going to be good at cuddling."

After KO and Screamer's plan worked, he basically collapsed from exhaustion next to you and Knockout in the lab. He wakes up around halfway through the movie, giving you a quick hug.
