Congratulations! You are the Conjunx Endura of Optimus Prime on post-war Cybertron. But there is a problem. You never wanted this.
Pairing: yandere! Optimus Prime x human! reader
You're looking at someone else's sky from someone else's window. And your gaze is sad. Cybertron is beautiful. Its two moons, its incredible sky, its beautiful architecture. It's all just great. It affects the human brain like the best work of art.
But it's not yours. No. Not yours. It will never be yours.
Your beautiful Earth, your beautiful home, your beautiful family… Everything was left behind, thousands of light-years away from Cybertron. You'll never come home. Because now you have a new home and a new family.
That's what your Conjunx Endura tells you. Optimus Prime.
Being human is a modest fate by the standards of the universe. Being a human who was appointed as a partner by Optimus Prime himself is something that countless beings dream of. Many. Except for you.
You hate Optimus. And your hatred is so blatant, so open, that no one doubts that if you had the strength, you would have killed Prime. Unfortunately, Optimus is almost impossible to kill. Even a great warlord like Megatron couldn't do it. And you're just a stupid weak organic person. Your punches, even on a Spark, won't do any harm. They won't do anything against this mighty metal body.
You hate your weakness. Because if you were at least a little stronger, you would be able to refuse Optimus. Optimus Prime is for you… He was blackmailing me. Oh yes, it was vile blackmail, unworthy of Optimus Prime, the leader of the Autobots and a fighter for the freedom of every living being. Optimus told you that either you're with him, or the Autobots won't protect Earth. It was a personal conversation. It was a difficult conversation. It was a conversation that resulted in you saying yes. Not because you were scared by Prime's threats, but because you knew they weren't threats. He's really going to do it. He refused to cooperate with humanity and the Decepticons destroyed the Earth.
You didn't want this to be the end of your planet. To all those billions of wonderful people. They shouldn't have died just because of your pride. Your fate, your life, your honor, meant nothing compared to the life of an entire civilization.
You hated your fate. Because your life with Optimus Prime is fate, an evil fate. There was nothing you could do. Should I say no? … no. Could not. That's why you're here, thousands of light-years away on Cybertron. Are you waiting for your Conjunx Endura in your shared compartment and thinking that maybe you should kill yourself? Why: it's an idea. If you die, you will no longer suffer for the whole world.
But you are too weak to end everything here and now. Too weak. Criminally weak. And you wait, like a devoted dog waits for its master.
Precisely! Master. That's who Optimus Prime is. Your master- and may he never accept such a designation of your relationship, you know it's true. Once Optimus says something to you, asks you for something, you will do it without asking unnecessary questions.
Not because you want to. Because you know the true price of rejection.
You didn't know why one of the most noble and high-ranking Cybertronians in the universe turned out to be the most primitive… A xenophile! A pervert! A nobody who directly threatened someone who was billions of times weaker.
But it was like that. Probably, everyone in this world had their own sins. And even a holy being like Optimus Prime was no exception. I wonder if the Decepticons still existed, would they use this situation for propaganda? Probably, yes.
The automatic doors open, and the only person who could enter the compartment enters. The blue optics of the Optimus Prime shine with a soft, calm light. After the Autobot victory in the war, Prime was… He's calm. Almost peaceful. He's always been like this. You've never seen Optimus Prime angry.
You hated being treated like that. Actually, it was one of the most intimate love affairs on Cybertron. Literally, "my Soul." Literally "my everything".
You would like Optimus Prime to consider you just one of billions of people.
But he called you his everything, and you nodded good-naturedly, welcoming him.
I wonder if Stockholm syndrome has developed in your organic brain? Optimus has never beaten you - if he dared, you would have died at the same moment. Optimus has never insulted you - if he had, you would have been morally destroyed. Optimus… He behaved very well. Respectfully. Except for the moment he took you into fucking slavery.
Optimus asks, coming closer to you. There's greed in his eyes. Prime shouldn't be greedy, but because of you, he's just like that.
"Just like anyone else. You know."
Of course he knew. Because you were under round-the-clock surveillance. Because you didn't have a chance to escape at all. Not even hope. Even…
"I've read the story of Cybertron. Thanks for the translation."
"It's the least I can do for you."
You hate him. You hate it because Optimus Prime doesn't behave like a typical rapist or maniac. He's behaving very well, but you know that's a lie. And the others? Do others understand this?
"Please don't call me that. I have a name."
Name. Not an animal's name.
"I know about it. I'm just honoring you as my Conjunx Endura. Don't you understand that?"
Optimus comes closer, looms over you, and you realize that you have nowhere to run. Your knees are shaking, and you're ready to cry.
"I'm sorry. I… don't deserve these honors."
"Nonsense. Who told you that? They always honor their partners on Cybertron. I, as Prime, do it too."
Metal fingers touch your back, lifting the edges of your clothes. You hate it. You're afraid of that. You know you're going to enjoy it, but at what cost?
"Optimus, I'm tired. I don't want intimacy, I…"
And you're silent. You keep quiet obediently and cowardly. Optimus looks at you carefully, almost getting his eyes under your skin. Into the very Soul.
"You're beating me up, my Spark. Did I hurt you? Did I offend you in some way?"
Yes! Yes, yes, yes! You want to scream that Optimus raped you, that he enslaved you, that you hate this planet, these creatures and this Prime, but… But instead, you just lower your head like a guilty child.
"It's hard for me to get used to Cybertron. And our interaction. This is human psychology, Optimus. I can't adjust to Cybertronian standards so quickly. I'm sorry about that."
You don't have to apologize, but you do it over and over again. Like an obedient trained animal.
"I understand. I'm sorry."
The touches don't go away. Optimus touches you more boldly, more strongly, more dangerously. You can hear the inner hum of his mechanisms.
"I'll help you adapt. Will you let me?"
Tears are streaming down your cheeks, but you nod convulsively. You take off your clothes yourself: Optimus never tears them, but you can't let him take them off you. It's humiliating.
"Thank you, my Spark. You'll never regret it."
You're already regretting it, but you still obediently spread your legs and let Optimus Prime call you his Conjunx Endura. Because you don't have a choice.
Probably, Optimus Prime with his madness has no choice either.
