Mermaids are described as either mortal (with or without a soul) or fairies, so they may or may not command powerful magic. Some can see the future, turn their tails into hot legs, call up storms, sink ships with tidal waves, and do other cool stuff. Others can sing... and that's about it.
Contrary to popular belief, mermaids can in fact do more than give head. I'd do with a mermaid, because I'm a pirate.
A. A whale
B. A dolphin
C. A fish
D. Any other sea creature.
Mermaid sightings have been popular throughout the centuries. Some time ago in the 1800's, a fisherman reportedly caught sight of some sort of creature in the sea, having the upper torso of a woman with long brown hair and a white tail speckled with black. Around the 1890's, two women drying seaweed on the ocean shore found a childlike female creature naked and playing along the shores. Days later, the child's body was found washed up on shore. She looked to be about four years of age, with pale skin and a developed chest, and what looked to be a salmon's tail from the waist down.
Mermaids have a very seductive nature, and almost always make love with sailors. No one knows they do this, but there is a theory that they are simply attempting to produce more of their species. When turned down on an offer of sex, though, the mermaid will be thrown into a fit of rage and slay the sailor who refused her pleasure.
Jimmy: well.. youre pretty arent you.. yes. pretty pretty salmon.. shal we fornicate in this torrent of water and make a bastard child and call it a mermaid? half man, half fish? yes? good. brace youre self..
Mermaids are known for falling in love with human men, and many ships and sailors are said to have been dragged under the waves by the watery nymphomaniacs. Others are known to play tricks on seafarers. Still others are known for saving people who are in trouble at sea.
Then there is "the mermaid problem": despite being an enticing woman from the waist up, it is not known how these creatures procreate, which has led many human males to great frustration and many mermaids to great confusion. Still, if you don't think to hard about it, it works out well... especially if merpeople have the ability to assume full human form rather than half-fish, half-human.
