His shirt and belt are dragged off and end up on a pile on the floor. He kicks off his pants along with his shoes (fortunately the king didn't have to wear the large boots that his companions had). He was now nearly naked save for his boxers and he was more than happy to be.

He hisses as Gladio's bites against his neck. His fingers dig into tanned flesh in surprise and he lets out a groan. His free hand continues to pet through Prompto's hair, down the side of his cheek and presses at the other corner of his mouth. If he didn't want to let Gladio do this, maybe he'd let his king.
