Steel and Skin Part 2 (Bayverse TLK Optikus Prime X Fem!Human Reader)
The night stretched on, heavy with the weight of what had just transpired between you and Optimus. His frame still trembled slightly, vents releasing uneven bursts of heated air. He held you carefully—almost too carefully, as if the sheer force of his emotions might break you. But he didn’t let go.
His massive servos curled possessively around your waist, pulling you closer, his helm resting against your smaller form. You could hear the deep, rhythmic hum of his spark beneath his plating, pulsing hard and erratic—far from the controlled, unwavering Prime the world knew.
He was still lost in you.
Optimus had spent centuries keeping himself composed, controlling every emotion, every urge. But you… you shattered that control. And now, he couldn't—wouldn’t—let you go.
His optics followed your every movement, hyper-focused, obsessed, drinking in every shift of your expression, every breath, every tiny quiver of your lips. You were his now. Completely.
His servo tightened slightly around your waist, just enough for you to feel the weight of it. His voice, deep and raw, rasped against your skin: “You belong to me.”
The words weren’t a question. They weren’t even a request. They were a statement of fact. A vow.
If another Autobot dared step near the outpost? His glowing optics darkened, his entire frame going rigid, positioning himself between you and them. They were no threat, not really—but the mere thought of someone else even looking at you made his circuits burn.
Jealousy settled deep in his spark, something he had never allowed himself to feel before. But now? The idea of you giving attention to another—laughing with someone that wasn’t him, touching someone that wasn’t him? It infuriated him.
“No one else,” he murmured, pressing his helm against your shoulder, his massive frame coiling around you like a shield. “Only me. Say it.”
You swallowed hard, fingers brushing the seams of his faceplate. He leaned into your touch desperately, his vents shuddering. “Only you, Optimus,” you whispered.
He exhaled sharply, and if he were human, you swore he would have moaned.
But even in his possessiveness, his devotion—fear crept in.
Had he been too much? Had he let himself go too far? The thought made his grip on you loosen slightly, his optics dimming with something that almost looked like regret.
He wanted you so badly, and for the first time in centuries, he had taken something for himself. But now, the weight of it terrified him.
He was a warrior. A Prime. A machine built for battle, for war. And you? You were everything he was not. Soft. Warm. Human. How could you ever truly belong to him?
“I should not have…” His voice wavered, and you had never heard it sound so fragile.
You reached for him, your hands brushing his battle-worn plating. “Optimus,” you murmured, commanding his attention. “I chose this. I chose you.”
His optics flickered, uncertain, searching. “Even knowing what I am?”
“Especially knowing what you are.”
And just like that, his resolve snapped all over again.
He crashed into you—holding, cradling, devouring.
This time, when he kissed you, there was no hesitation, no restraint—only pure, unfiltered devotion.
Optimus had fought every battle, faced every enemy—but nothing had prepared him for this.
The instinct was primal, something ancient buried deep within his coding. Now that he had you, his entire being demanded more.
He had always known about sparkbonding, the Cybertronian act of permanently linking one’s spark with another’s essence. It was irreversible. Sacred. And now…
His fingers trembled as they traced your skin, optics burning with something deeper than desire—something eternal.
“I want to bond with you,” he admitted, voice raw. “To make you mine, forever.”
You felt the weight of those words. Cybertronians didn’t bond lightly. It was a lifetime commitment, a merging of souls, a connection that no force in the universe could break.
“What does that mean?” you asked softly.
He gently cupped your face, his digits careful, reverent. “It means my spark will recognize you as its mate. That I will always feel you. That no matter where you go, I will be with you.”
His vents hitched, his body trembling with restraint. “But if I do this, I will never be able to let you go.”
The weight of his words settled deep in your chest, but there was no hesitation when you whispered: “Then take me, Optimus.”
His entire frame shuddered violently, his optics burning with unrestrained devotion.
He pulled you flush against him, his servos curling possessively around your body. His chest plating shifted, parting slightly, exposing the faint, pulsing glow of his spark. You gasped as the warmth of it enveloped you, a sensation like nothing you had ever felt before—like pure energy, raw and electric, pulling you in.
And as you reached toward it, allowing yourself to be claimed by him, Optimus whispered your name like a prayer.
Because tonight, you were not just his lover.
You were his bonded love. His forever.
