In this fantasy, mermaids are beautiful and gorgeous creatures, possessing a long lifespan and are exclusively mono-gender females (so no such thing as mermen) who have the ability to reproduce with a partner of any other race or species, though they mostly prefer human males to procreate since only with whom they can produce more mermaids. Longingly referred to by sailors and disdainfully by human women as "sea sluts", they're known to lure men at sea with their melodious voices, and once in sight, the men are ensnared by their beauty. Contrary to some beliefs, spread by women and the celibate, mermaids are not intentionally malicious nor do they have a taste for human flesh. A mermaid instead takes a man of her choosing to an isolated location and would spend the rest of his days having sex with her. He was essentially kept to fulfil her insatiable sexual appetite and milked daily of his sperm, subsisting mostly on her breast milk that could keep any man virile and ensure a steady supply of his cum for her.
Depending on the health of the mermaid's partner and that the mermaid managed to restrain her voracious sexual appetite to not exhaust him to death (happens more often than not), she would eventually give birth to another mermaid, inheriting some traits of the father but mostly resembling the mother in beauty and longevity. On certain ideal circumstances a man can end up creating a new pod of mermaids if he managed to do so with each generation.
This is partly due to mermaids having an accelerated growth period from birth to maturity compared to humans, transforming from a child to a fully developed and mature mermaid within half a decade, and by then their ageing process drastically slows to the point that they retain their youth and beauty for the rest of their long lives.
Mermaids are naturally and inherently promiscuous, having many sexual partners throughout their long life and have bisexual relationships among themselves in between. But customary of mermaids they are not permitted to have their first sexual intercourse with a human male until they've "come of age". And this is where Ariel's story begins.
Ariel is the youngest of her seven mermaid sisters. She has voluminous flaming red hair, big aqua blue eyes, fair skin with a smattering of freckles on her nose, cheeks, and shoulders and full ruby lips. Her breasts are exceptionally large for mermaids at her age but characteristically perky and supple, tipped with sensitive pink nipples. Her slim waist spills out to wide hips and a juicy peach bum. Like all mermaids, Ariel's sea green fish tail begins from mid-thigh joined together, leaving a sufficient pussy gap that allows her kind to be taken from the front or the rear. As customary of mermaids, Ariel wore no clothing except for a few bracelets and pearl earrings.
Ariel was close to her mating stage, and she had seen her sisters each time take men away from their boats or the seashores and, depending on how long the man lasted, be away for months and even years in their honeymoon lagoon or cove, only returning after their partner had expired but not before depositing all their seed into them. She had watched longingly as their bellies swelled with new life, as a thicker trail of milk flowed from their swollen breasts wherever they swam.
