Fingers wrapped around the end of his hair, and before Ed could even process it, he was being yanked backwards. "O-oow—" Edward stumbled back several steps, more startled than hurt; he grabbed the base of his braid indignantly, spinning around as soon as he regained his balance.
He spun right into Mustang's lips. "!?"
Mustang smirked as he pulled away from the brief, closemouthed kiss. "Watch your braid, Fullmetal— you never know when someone might use it against you."
Ed growled under his breath, color high in his cheeks, and pulled away. "Only you, Colonel," he snapped in reply.
