Optimus Prime and Megatron but they're an old married couple <3

Megatron had waged wars, toppled empires, conquered worlds. And yet nothing — nothing — could make him hesitate like the sight before him now. Optimus Prime, the great Autobot leader, stood at the stove of their shared quarters, framed by the soft, golden light of the galley. An apron — a blue apron — clung delicately to his waist, tied into a neat bow at the back. Megatron almost laughed. Almost.

He had meant to pass through the galley. Truly, he had. But how could he resist when Optimus looked like that — helm tilted, posture perfect, waist narrow and hips moving ever so slightly with each turn of the spoon? The Prime was radiant, and Megatron, ever the warrior, had no defense against that kind of beauty. He crept closer, smirking to himself, servo reaching out— until his arms wrapped fully around Optimus’s midsection, chest pressed to his back.

Megatron chuckled against his neck plating. “Before you scold me... I’m not interfering,” he said, letting his claws ghost over the soft blue fabric of the apron. “I’m admiring craftsmanship.”
