In his human form, Aidan is slower under water than Kai is. The tickle makes him laugh as he dives, twisting under water to circle around Aidan, his back curving as he makes a circle around the man, then comes up in front of him, not quite surfacing. His arms go over Aidan's shoulders, legs slowly wading water beneath.

Kai leans in close, as if he's going to press another kiss to Aidan's nose. It wouldn't be all that unusual if he had been in his seal skin. But when he gets close enough, he blows bubbles on Aidan's face, laughing, his voice more like clicking under the water.
