Yuuri doesn't last, doesn't try to last, lets all of his tension go with it, all of the difficulty and embarrassment and how unsure and uncomfortable he was. He doesn't need any of it, not here, not with Viktor taking care of him. He's loud leading up to it, but almost silent when he finally releases, air breathed out in a sigh of relief that leaves him boneless and, unless Viktor has other grand plans, sinking to the ground into his arms when he's done.
