Gladio chuckles as Noctis whines, flushes and then bats his fingers away, cat like as ever. They wouldn't be his close friends unless they teased the king so, but Gladio isn't going to spend much more time on it when Prompto has eagerly and willingly scooted into position for him.

"Good enough for you, Iggy?"

He asked, gloved hand running through Prompto's hair and down his back, all while Gladio leans in to kiss the top of his spine.

"I'll leave the decision up to you, if not, then well..."

With his free hand he offers Ignis his belt, brushing it against his shoulder to let him know it is there. Wouldn't be the first time they've bound Noct up, after all.
