To be fair, this wasn't Kise's idea either. He spent a couple seconds brain dead from embarrassment before his brain rebooted and he jumped back from the wall, accidentally taking Kuroko with him because the other had wrapped his arm around him.

So, there they were, standing in the middle of hot spring, Kise naked and certain parts of his anatomy taking notice of being in close proximity of a cute boy attached to him. "Fuck," he groaned and gently pushed Kuroko back before parts of him became too... too much everything. His brain going 'oh shit, oh shit' and convinced Kuroko had noticed his body's reaction.

And then he ducked under the water, covering himself. Half tempted to drown himself while he was down there.
