Regulator trouble(?) (Patreon)

Akari and a dive buddy of hers find the remains of a sunken ship beneath the waves;  exploring the wrecked passageways and cabins, she inexplicably finds herself in a certain mood...

She points at her regulator;  thinking she's in some kind of trouble, her companion prepares to share his air with hers.  However, she swats his hand away, and instead kneels onto the deck until her face is level with his groin.  Akari then quickly unlocks the fasteners of his wetsuit's jacket - the beavertail pops free, exposing the relief zipper of the suit's trousers.  It shouldn't take much imagination as to where this will lead to next.

You'll find this illustration without any annoying sea fog in the Dropbox;  enjoy!
