The offer made Tony roll his eyes, wondering at the formality. If Tony wanted something, Pietro definitely wouldn't have to ask him or fuss over him in any way. He almost told Pietro to relax, but before the word was out of his mouth he was dropping his head with a wry smile at the hypocrisy that would be in it, and decided to focus on relaxing himself before he told anyone else to.
"Maybe for a little while," he said instead, reaching out to touch Pietro's jaw again, still at an arms length while he stroked his thumb over Pietro's chin. His smile was turned on the younger man then, his head still cocked, and it would have been inviting if Tony didn't accept the invitation himself, stepping in to nuzzle under Pietro's ear with a decisive hum. Pietro should keep it.
