Gladio was aware that it was teasing, but it still had made him grumpy on occasion. Getting Ignis to say the words now brought hin great pleasure, and he bites a mark dark on his skin once he is satisfied with his words.

"Fuck- Thats good, thats what I wanna here. You are all mine and I am all yours."

Gladio sighs happily and finally, finally rolling his hips up as he lets Ignis push down, sinking deep into him in a slow push. He takes his time in this particular moment, wanting his lover to feel good even as he feels the stretch, and he groans happily as he nuzzles into his neck.
