That pinch earned John a sharp growl, glaring briefly before giving a nip in return. He wouldn't take nicely to that any more than John was taking to his bites. Still, his smaller Guide has already proven to be able to urge him around, and even if he doesn't realize it, the command-reward system is already starting to set in his mind as he does as he's told, his eyelids fluttering as John's approval surges through him.

It's a damn fine choice as John's hands wrap around him, leaving Gladio to look down with hungry eyes to John, rolling his hips in the time that John set. With John's hands busy, though, he had every ability to be able to speak, dipping his head down to rumble. "Do you have any idea how good you smell? Better than any Guide I've ever scented... you smell like a fighter. Like gunsmoke. I can taste it on your skin, every time." His mouth finds John's shoulder and sucks gently.
