A sound of door sliding open pulled Zero out of sleep. He groggily rolled from the middle of the bed to make some space, scowling at how cold mattress was there. But it was fine, cozier spot was for someone more important. Blond waited, not even opening his eyes. He didn't need to, only one person knew his passcode.
Main door closed and familiar footsteps followed. Than the bedroom door opened and closed, footsteps got closer. And than someone sneaked in the bed, nestling in the warmth.
Blue eyes opened with a little smile.
"Got lonely again?"
"Mhm."
Zero tucked the cover around them to keep cold air, and probably rest of the world, away. X snuggled to him with a content sigh, letting blond hold him close. Smaller reploid smiled, feeling Zero nuzzling his hair.
"You know, why won't you always just come to sleep here instead of sneaking around in the middle of the night?" Zero murmured, combing his fingers through chocolate locks.
"As if the entire HQ didn't have enough gossip fuel."
"It's none of their buizness. They can talk all they want. Not that they would be wrong, anyway."
Zero gave X a short, loving kiss to prove his point. Having X immediately pull him in for another, longer one was just a nice bonus and blond happily went with it.
