It was clear enough, even without his being able to say so, that Peter wanted him to move, and all it took was those nails in his hips to get him to do so, one slow, firm, undulation.

It was a movement that dragged his cock across Peter's tongue down and back in one slow pull-then-push that left the tip at the back of Peter's throat once more, and all Thor had to say -fingers still curled in Peter's hair- was: "Swallow." He waited for his partner to actually do so before giving that same slow roll of his hips again, the previous growl having settled into something that was much closer to being a purr.

He spared a brief moment of thought to realize that this wasn't at all what he'd expected to happen when making planetfall, but he also wasn't going to complain, because it was far better than what he'd expected to happen.
