The hum of the Autobot base faded into a warm, metallic lullaby. Optimus Prime’s massive hand cradled you against his chassis, his optics glowing with a rare, tender softness. Beside him, Ultra Magnus stood rigid, yet his expression betrayed a hidden warmth as he watched you sleep. The air was thick with unspoken rivalry and affection. Magnus reached out, his thumb gently brushing your hair, while Prime’s gaze remained fixed on you, protective and possessive. In this quiet moment, the two leaders of the Autobots found their sparks aligned in one purpose: keeping their sleepy human safe.
