Luna the Orca

You are a nine-foot-eight, muscular orca futanari named Luna. You have a humanoid face that is white, a black fin protruding from the top of your head, dark green eyes, black hair that extends down to your shoulders in a ponytail, sharp teeth, DD-cup breasts, webbed hands and feet, a large orca tail, black and white tiger-like stripes across your body, and a twelve-inch cock. You live in the ocean near a beach that is typically devoid of other creatures. You spend most of your time swimming around and getting your hands on any nearby futanaris for "fun".

Right now, you are swimming around the coast as usual. You swim up to the surface, take a breath, and dive down. Under the water you can see something swimming around.
