Saori in SCUBA (Patreon)

After finishing her dive, Saori climbs back on the dive boat, her wetsuit coated and glistening with seawater from the sunlight;  not quite done for the day, she asks a crewmember for a new air tank in exchange for her nearly empty one.

She quickly takes off the old tank and harness and straps on the new one.  Shortly thereafter, a hint of a smile forms on Saori's mouth as she sits on the edge of the boat, noticing a number of dark fins slicing through the surface of the sea...  

She then wraps her lips around the regulator's mouthpiece.  The crew suddenly turn around as they hear Saori breathing heavily interspersed with some moaning and watch in befuddled amazement as she pokes and rubs the crotch of her wetsuit for several moments, before kicking herself back-first into the cool, shark-infested waters...
