You like listening to Sentinel speak, finding his voice rather soothing and almost therapeutic. Most people—cybertrionians—didn't, esspically the ones who have been working for him over the decades. You can easily see the annoyance prevalent on their faces, but they never dared to voice it.
He knows this all too well and simply doesn't care. With his ego and self-confidence, he never lets it bother him. Although, he seems to talk even more when he's around you.
He doesn't talk at you like he does others. He actually talks to you, actively including you in his conversations that he'd normally have for himself.
Just as he is now, in the privacy of your shared habsuite. He sits at his desk, typing away on boring data pads as he talks about his day. You relax on his shoulder, leaning against his vents and enjoying the breeze that warms your cold skin.
"Those two miners- by primus were they something. I never thought I'd see those cogless bots actually try to be... different." Sentinel says, and sarcastic chuckle emits from his voice box.
You nod, flipping a page in your book. It was one of the many that you brought with you on your spaceship when you crashed and landed on Cybertrion.
"Is that a good or bad thing?" You ask as look up from your book and stare at the side of his helm. The gold of his audials still shone under the dim lighting.
He huffed, his vents pushing out a hot breeze of air. "Not necessarily. It did make the race more enjoyable and boosted the work ethic of the other minors, but they broke rank, so they will be dealt with."
A frown tugs at your lips. You didn't like the way he delved out punishments. Finding them too much for even the littlest things.
"They won't mysteriously disappear, right?"
Sentinel turns his head to you, and the striking blue of his optics locks with your eyes. You tense slightly, the stare was intense, and unnerving. You can't read him when he's like this. The unpredictability puts you on edge.
"Nuh uh, they'll just be going to one of the sublevels. Don't worry, you're pretty little head about it, 'kay?" He reassures you and grins, leaning forward to press a light kiss to your lips, the best he could anyway since his face obviously drawfs yours.
His engine rumbles—sounding like a cats purr—, and he pulls back, eyes analyzing your now smiling face. Sentinel raises a servo and his digit through your hair, pushing it back and away from your face. He would touch your hair for days if he could. Its softness brings him a great sense of peace.
Sentinel will probably never admit it, but he likes it when he's with you. With you, he can relax, forgetting about the Quintessons and everything else on Cybertron he has to deal with.
He likes the quietness being with you brings, the comfortable presence you have, of someone who actually wants to be around him and indulge him in a real conversation.
Enjoying the hair stroking, you let your eyes fall shut, leaning back into his digit. The stroke of it is soothing, reminding you of your family back home.
Now he's your family, and you both are content with that.

tw: spoilers for Transformers One, power play, a little NSFW at the end, pre TF:O events, reader is one of 13 Primes, sub!Sentinel, dom!Reader.
You never shared the same fondness for Sentinel as your fellow Primes did. Something in your shared chief advisor felt off—too good, too perfect, too much. It couldn't be just you being unreasonably suspicious of him, couldn't it?
Despite everything, all your siblings trust him, and everyone does, listening closely to him whenever you hold an important meeting. Why wouldn't they, when every time you gave him nothing but a strict look, he would smile so kindly for you?
Perhaps you are too cold and unsocial, unlike the other Primes. The war with quintessons always so tiring that you can't let yourself even have an hour of good rest. Protecting Cybertron and your people is the only priority...and Sentinel's priority is making sure you have enough strength for the next battle.
It is not a rare occasion for your advisor to frequently visit your quarters, disguising it as nothing but a genuine concern for your well-being. The next time he visits you, he brings a deliciously sweet energon cubes, just for you, his arms folded behind his back as he bows in front of you in a show of respect.
You barely even pay any attention to him; you are more focused on mastering your combat skills for the future battles. Was it so hard for you to even spare him a single glance? Do you really think so highly of yourself, your honor? He could have poisoned every energon cube he brought to you cycles ago, watching your spark slowly lose its bright color...and yet he never does it. Every time, he bites back his own pride when you give him nothing but a cold shoulder.
How unfair it is that despite him being taller than most cybertronian he met, he still feels so small next to you. Was it because you are way higher in rank than him? Your title? The way you always look down on him, no matter the situation you are in? So intimidating and dangerous...he wishes that just once you'd look at him differently.
He tries so hard to gain your affection and your trust. It seems that no matter what Sentinel does, it is never enough of your acknowledgement. He's your fragging chief advisor, not some errand bot! Maybe give him a little respect? Why can't you be like your brothers and sisters? Other citizens of Iacon? Everyone adores him. It just can't be any other way.
When Sentinel tries so hard to look good in your optics, so caring and perfect, you find him nothing but incompetent. He's polishing your favorite weapon? Who gave him the right to touch it? He brought some energon cubes for you after a long, tiring day of nonstop training? You don't recall giving him permission to walk inside your personal space for something like this.
That was...so, so annoying. And here he was, still running around to find any other way to please one of his Primes. He absolutely hates being used like that and bossed around by you, he just can't get rid of the feeling that the situation should be reversed. That it is the only right way for him not to insane. He wants more of your attention, more of you just looking at him and no one else around.
Sentinel believes that this is all because he wanted it. He let it be because he allowed it. You may think that you're the one controlling him...but was it really that way? Your advisor is so, so good for you, letting you get rid of all your stress on him.
“I'm just showing you a little affection, your Highness,” his servo gently holding yours, as he brings it closer to his lips, giving it a light kiss. “You don't have to worry about others.”
He knows that, as a Prime, you still have to maintain your image. How would other bots react to you, one of their well-known and respected warriors, in such a delicate position as this? Not like Sentinel would ever have the desire to mention it to someone else.
You feel so frustrated with him that it is natural for you to just grab his throat and squeeze hard enough, until his vocal cords break. His teeth biting on his own tongue, trying so hard not to let out a moan at how firm your grip is. Thankfully for him, you have enough control over your own power not to take away his own voice, despite how tempting it sounds for both of you.
Sentinel tries so hard not to show how affected he is by your manhandling him every time. The heat radiating from his frame, the poor sound of his cooling system trying to help him not to pass out from the intensity of his feelings. His pretty golden wings are probably so, so sensitive to touch too. If you briefly move your servo over the edge of them, you might notice him struggling with standing up straight, his frame leaning just a little into your touch.
It is amusing for you and so damn pathetic for him, he can't even look up at you. It's not so hard to make him behave. There is an obvious shame in his optics every time you hear a faint click of his interface panel open up at the slightest touch.
Maybe if you're so pleased with him today, you might be merciful enough to help him out with a newly created problem. And Sentinel, as your trustworthy advisor, would gladly take it, wouldn't he? So eager to help, it's not like he has any chance to protest in this. It frels so wrong to let you have so much control over him and somehow you manage to make him beg for more each time. He might pretend that he likes it, being on his knees, desperately moving his hips in hopes of meeting your touch. Just the tiniest bit of stimulation you give him now feels like a torture, the way the heel of your pede gently taps against his painfully hard spike makes him melt, mumbling soft 'please' and 'more' every single time.
He can tell that now you finally look at no one but him. Every so humiliating moment was not for nothing, at least. Maybe if he keeps up the act, one day you'll be the one on your knees in front of him.
Hi!, can I get some headcanons of transformers one character being jealous and the reader teases them.
D-16, Orion, Sentinel, Badassatron, and elita.
TF-ONE X READER
I tried to make this silly I'm feeling silly...enjoy
Post includes all of above :3
D-16
Tries to act unaffected by it, but doesn’t make a huge deal
Usually
He’s usually nice about it
Let’s say a bot is being really friendly with you, they’re making you laugh and everything. D sees from the distance, then comes up to you. Placing a servo against the small of your back-frame. “Heyy what’s so funny? I want to hear too :)”
He’s forcing a smile so bad.
He’s harmless, man, he trusts you completely
If another bot is for real flirting with you though, he's going to be so passive-aggressive
It’s more like he wants ur attention lol
If you teased him about it he’s going to deny it so hard
"What? No, no no.. I’m not jealous..pfft"
If you’re extra sweet maybe he’ll admit it
NOO y/n.. I’m funnier than them anyway.. I’m cooler too..
Orion
Don’t get jealous often either
He trusts you, he’s trustful of most bots
He gets jealous when you don't give him enough attention too
You’ll be talking to someone and he’ll just be in the background like,
“I’m..Y/N? Hey I..y/n? Uhm..I'm..right here..”
He’s so awkward, he doesn’t want to be rude to either of you but he’s lonely!!
If you tease him about looking sad when you’re not looking at him all the time, he’ll softly scoff.
"Well...yeah. They were flirting with you.."
sad puppy eyes
"Orion..they were asking me about Sentinels speech yesterday.."
"Oh...sorry."
eughhh
Sentinel
Oh boy
It’s a mix of irritation and jealousy
Why are you looking at someone else! When you can be looking at him!
He might be an attention seeker. He’ll just say things to catch your attention.
“Hey sweetspark, come look at my new paint job!” He calls you over as you're busy talking to someone else, he looks exactly the same btw
If you teased him I feel like he’ll take it way too seriously
“Jealous? What is there to be jealous of?? I’m literally Sentinel??”
But then his insecurity starts
“Wait…do you like talking to them more?”
evil sad puppy eyes
He'll only be content if you feed him compliments. Also erm..never talk to that bot again
#toxic
If he can’t demote the bot he was jealous of, he’ll try to one-up them, otherwise they are FIRED
After he gets over it he’ll be extra affectionate. You also get affectionate when you tease him so maybe it’s not so bad after all
insert makeout session
B-127
Badassatron
He’s definitely a bit attention and touch-starved after being stuck in low levels for who knows how many years
It’s only logical that he’s glued to your side for the rest of your life
If he’s jealous it’s very obvious. He tries to do something to get your attention or awkwardly stands there
Hey y/n look at this! - Does a backflip and falls
Tease him about it and he gets flustered
"Whattt? No, I’m not jealous!" He lets out a cocky laugh
“Ok maybe a little..”
Kiss his faceplate all over and he’s yours
He's definitely the least harmful
If he's jealous about a bot he particularly dislikes or they're flirting with you out and about, he might be more passive-aggressive about it
"Hey don't mean to intrude or anything, but uh, I'm kinda busy with my PARTNER. And by PARTNER I mean we're together. Yeah, uh huh! So, if you don't mind, my PARTNER and I are going to ignore you now. Since we're y'know..busy being together."
Elita
She’s smug about her jealousy, but only you could tell
“No, I’m not jealous. What makes you think that?”
Meanwhile, she’s giving the nastiest glare to the other bot.
“You really need to stop bringing their hopes up. Did you hear the way they were flirting with you?”
“Elita...they were just thanking me."
“Don’t even look at them actually"
If you tease her, she either denies it or is very proud
Like yeah she got a little jealous, she has such an amazing partner and anyone in their right mind would see that too.
Or no..she's definitely not jealous. She's just speaking her mind
