Optimus hesitated for a moment, scanning the streets. The city hummed with life, but the tension in his spark made him grip Megatron’s hand tighter. They entered the base through a hidden entrance. Immediately, Optimus froze. Guards patrolled silently, weapons gleaming, optics glinting with suspicion. His spark raced.

Megatron noticed and chuckled softly, wrapping a protective arm around Optimus’ shoulders.

Optimus blinked, trying to calm his racing thoughts, and allowed Megatron to lead him deeper. Despite the danger all around, there was a flutter in his spark—a strange mix of fear, excitement, and something… intimate.
