Sasuke's face is painted in that cocky, easy smirk from the word go, entertained by Naruto's plight - but it's not long at all before his expression follows the other's suit, teeth showing a bit in a real smile, mirth sparkling in his eyes, and he's laughing just the same, if softer - Sasuke's always been quieter, even if he's learning to open up - as they half-spar and turn each other's strikes and exchange nothing-blows and just tussle like fucking teenagers, for once.

That palm to his stomach blows an oof out of him, makes just enough opening that he fucking blinks and misses it when Naruto slips out of sight. Curses under his breath because god damn it, when has he ever been without his chakra - and then he YELLS when he's grabbed and hoisted right the fuck off his feet into the ocean.

He comes up spluttering and cursing a blue streak, punching a splash of water at Naruto's face as soon as he gets some tread under him. "Cheap shot, Uzumaki!" But while there's bite and there's offense, there's still no ire and there's no bile. There's just Sasuke, snorting under his breath before using a push of his now-waterlogged wings to get some extra oomph into his pounce, aiming to push Naruto's head back under the water under his forearms.
