Yandere One-Shots (Volume 6)

Enemy Turned Yandere Whip Hybrid X Male Optimus Prime Reader (Lemon)

(The city skyline stretched across the horizon, bathed in the warm light of a setting sun. From the ground, it looked peaceful, like any normal day. But high above, hidden from view, two figures were locked in a quiet confrontation, one that had taken place many times before. Optimus Prime, the leader of the Autobots, stood on the rooftop of an old, abandoned building, his human disguise concealing the power beneath. His youthful form—a boy with blueish hair, wearing a red hoodie—looked ordinary and his civilian name was Y/N Pax. But there was nothing ordinary about him.)

(Across from him stood Yui, a deadly Whip Hybrid, her lithe figure silhouetted against the fading sky. Her long, dark hair framed a face that was both striking and cold, but her eyes held a strange intensity, locked onto Optimus. For so long, they had been enemies, clashing in battles across cities and fields. But recently, something had changed. The way she looked at him, the way she hesitated during their encounters—it was no longer the gaze of a relentless foe. There was something more behind her sharp words and precise attacks.)

Something far more dangerous.

Y/N: You've been following me again.

(Y/N said, his voice calm but firm as he watched her. His disguise masked his true form, but Yui could feel the presence of the Autobot leader, the strength and resolve that always radiated from him. Yui's lips curled into a small, almost playful smile.)

Yui: I wouldn't call it 'following. Just... keeping an eye on you.

(Y/N frowned slightly, trying to read the emotion behind her words. Yui had been an unpredictable adversary, her whip-like abilities giving her an edge in combat. But lately, she had stopped pushing him to the brink. Instead, there were moments—fleeting but noticeable—where her attacks would falter, where she would let him go. And now, standing here in the twilight, it felt like their rivalry had shifted into something else entirely.)

Y/N: Why are you really here? What do you want?

Yui: I think you already know the answer to that, I've been thinking about you, Y/N. A lot.

(Y/N felt a strange unease settle over him. For so long, he had viewed her as nothing more than an enemy, someone to defeat in order to protect the humans and his fellow Autobots. But now, the way she was looking at him—it wasn't with malice or hatred. It was something deeper. And something he hadn't expected.)

(Yui reached out, her fingers brushing against the fabric of his hoodie.)

Yui: ou and I... we've been fighting for so long, haven't we? But it's not the fighting that keeps me coming back. It's you.

(Y/N's breath caught in his throat. He hadn't anticipated this, hadn't seen this coming. But the way she spoke, the way her eyes softened when she looked at him—it stirred something inside him, something he hadn't allowed himself to feel before. Could it be that beneath their battles, beneath their roles as enemies, there was something more?)

Y/N: I don't understand. We've always been on opposite sides. Why now?

Yui: (smiles softly) Because I realized something, I realized that I don't want to fight you anymore. I don't want to hurt you. I want to be close to you, Y/N. I want to be by your side.

(Y/N felt his heart race as he looked down at her, her eyes filled with sincerity. He had fought countless enemies over the years, but no one had ever said something like this to him. No one had ever crossed the line between adversary and something more. And yet, as he stood there, staring into Yui's eyes, he couldn't deny the truth.)

(He had felt it too.)

Y/N: I... I never thought this would happen. But I understand.

Yui: (whispers) You feel it too, don't you? This connection between us. It's not just about fighting anymore.

Y/N: (nods) I do. But I don't know what this means.

(Yui's hand slid from his chest to gently cup his cheek, her touch surprisingly tender for someone who had once been his enemy.)

Yui: It means you don't have to fight alone anymore. It means you belong to me, Y/N.

(Her words sent a shiver down his spine, and for a brief moment, Optimus considered pulling away. But then, something inside him shifted. Maybe it was the years of loneliness, the constant pressure of leadership, or the fact that, for the first time in his life, someone truly wanted him. Not as a leader, not as a symbol, but as a person.)

(She then pins him down, and removes her clothes before pulling his pants. She then rides his dick as he grabs her hips to help her to move faster.)

Yui: Oh, darling...

(They keep going for hours until they cum massively.)

(Some weeks later, Y/N and Yui are seen at the church as the priest speaks up.)

Priest: By the power vested upon me, I now declare you husband and wife. (to Y/N) You may kiss the bride.

(They then share a passionate kiss.)

(One month later, Y/N is seen in his true form as he leads his group against Makima and her associates who sided with the Decepticons.)

Optimus: Autobots, roll out!

(They then charge at Makima and the Decepticons. Y/N knows he doesn't have to fight alone anymore.)
