It's not just a laugh but giggles, something carefree and unburdened and it makes Gladio laugh as well, soft and amused, rolling in his chest. He shifts his focus from kisses to rubbing his jaw against Ignis, grinning and intentionally letting his beard scrape over delicate skin. It tickles, Ignis is right that if they fall over it's going to hurt.

None of that means a damned thing when he can make Ignis laugh like that, though.
