[Story]

The deep ocean is beautiful.
It is a mystical world that can only be known by people who have been to its depths.
It is a world where, in addition to satisfying your curiosity, you can be submerged by danger or swallowed by fear.

You know that sometimes fish can attack humans, right?
Sharks in the sea, piranhas in lakes - you have heard of fish that attack humans.
It is not well known, but men and women are attacked differently.
Men are just caught like bait.

However, women are seen as vessels (raped).
In biological terms, this is known as "fish rape".

We still do not understand this scientific mechanism.
Do their diver suits which show a clear body line excite the creatures in the sea? Does the love juice excreted from the crotches of the girls spread in the sea, and do they smell that odor? There are many theories.
However, if we think that all creatures, including humans, come from the sea, it may not be such a strange thing.
Female genitals progressed in abalone, and it is deny to say that their squirting function is remnants of that.

So how are women fish-raped?
When women are attacked by the fish, nearly always the fishes genitals enter the female genitals.
In particular, killer whales and sharks have large genitals, and if human women have those genitals inside them, they won't stand a chance.
Swimming in the water, they use up all their oxygen and die.

Octopus and squid catch women with their strong tentacles, and steadily rape them.
Of course, finally women run out of oxygen and die.

You can't even underestimate small fish.
It is said that as many as 150 women divers are raped by fish and die every year.

Now we are in an age where it is easy to go diving, so knowledge of the deep ocean and the guidance of experts is required.
