He ought to be expecting it enough that it's less surprising this time, but he yelps again anyway. He's still not sure about the actual spanking part, but the aftermath is so ridiculously good he's having trouble figuring out which way is up already. There's something magic about moments where he's completely out of his head with something, a feeling he's always chased down on the ice, but having it catch up with him, somewhere unexpected, keeps throwing him for a loop in the best possible ways.

He's buried himself again, but it's clear to see this time that's just because he needs to cling harder, one hand fisting probably a little uncomfortably in Victor's hair, but he really just needs to hold onto something and Victor's the only thing available. The inevitable firmer grope afterwards has him moaning, writhing down more into Victor, both chasing friction and completely unable to be focused about it.

Victor's definitely going to have to talk him through freaking out a little bit about this later, but it's probably worth it for how desperate Yuuri sounds when he finally does manage to form words,

"Please... please," his voice almost breaks on the second one and lest Victor think for a second that he's asking him to stop, he's pushing his ass back into his hand again.
