Tony's reaction just makes Thor laugh louder. Thor found all humans adorable, but this one, even spewing up nuts into the sand like there's no tomorrow --

-- is definitely the most adorable of them all.

Especially when he makes threats.

"Good luck with that," he challenges, still tickling Tony. And since he can't trust more nuts (were there more? Thor wasn't sure) to spew from Tony's mouth, he plants an affectionate kiss on Tony's forehead instead of his lips.
