There is a place where the sea is strangely white around where the Orca is anchored.
It is a place exclusive to Alcyone, where no other bioroids access it.
Once, or twice, or even three times a day, when Alcyone's sexual impulses reach their limit, she visits the White Sea.
And there she begins to show off her sexual prowess....
She ejaculates in the sea because the land is too small to hold the amount of semen she releases.
