Ignis is quiet and Gladio does not mind, knowing that was how the other just was. It took a lot more than just getting him to submit, and he loves those few breathy and catches noises as much as he loves it when Ignis can't hold back voicing himself.

He can see Ignis' cock hardening with interest, but now isn't the time to touch quite yet. He presses his mouth to the top of his head again before standing, moving behind Ignis now. They have always done this in a certain way, and he knows the little stages of it where Ignis needs to be touched softly and lovingly, or when he needs Gladio to be purely focused on spanking him.

Another crack of his hand hits his ass, layering them over each other now to blur pleasure and pain. He undoes the shirt garter on one side and spanks the other for each clip that needs to come off, less time between hard smacks this time that net him neatly eight in a row, four for each garter as he tosses then off to the side of the bed.
