Today was the great day for Tom. He had prepared everything: he studied the currents, traded stories with fishermen, brought his most trusted pair of swim fins, and even bought a (grossly overpriced) breathleaf. Today he would catch the biggest boobfish - ever.
But what is a boobfish, one might ask? Well it probably has an official, boring and presumably Latin name but the locals prefer the more colorful terms like fisherman's mistress, cock-thief, and of course boobfish, the last one being the most common.
Despite the name, the boobfish is not actually a fish, though it does live in water. The easiest way to describe it is to compare it with a mermaid: the mermaid is half girl and half fish; well the boobfish is half girl and half boob, but on a smaller scale.
The human part of the creature is about 6 inches tall, and looks like a miniature woman, with legs that merge together at feet level. Both legs are very flexible and act as labia that lead towards a large digestive sac floating behind her. This digestive sac is what gives the boobfish her name, since it has both the size and appearance of a female breast, up to the nipple at the rear end.
The boobfish is a predator that hunts small to medium size fishes, and uses the powerful suction of her breast-like pouch to catch its prey. Once the prey is sucked in, the front labia/legs close tightly, and the water swallowed along with the prey is drained though the nipple. The victim is then doused with digestive enzymes mixed with a light narcotic to prevent any undesirable squirming or biting.
Men being men, it was soon discovered that the boobfish often mistook a penis for one of her prey. Very shortly after that, it was also discovered that the insides of a boobfish were soft, warm and that the peristalsis motions of her flesh felt heavenly.
'Boobfish hunting' became a popular activity among the young male population of the island, and is quite harmless as long as you follow this rule to the letter: once your member starts tingling, you take it out.
Those that do not follow this wise piece of advice risk severe burns: the boobfish digestion process is painless and actually increases sexual pleasure, making it impossible to tell how far the digestion progressed. For the foolish few that persist for more than a few hours, there will be no warning until the boobfish starts swimming away, what's left of their penis safely digesting in the breast of their new owner.
But let's get back to Tom and his quest. Tom had been a wise boobfish hunter ever since he learned what the thing between his legs was for. Unfortunately for him - or fortunately depending on the point of view -- his member had grown to such a size since reaching adulthood that the boobfishes he loved so much could no longer swallow it in its entirety.
Recently though, he had overhead sailors that drifted too close to the coral reef brag that they had spotted boobfishes there that were twice the size of those you could find near the shores. He would have dismissed that as senseless boasting if the captain hadn't told the same story.
It did made sense. The coral reef provided plenty of game in en enclosed space, making the hunt easier for the slow moving boobfish. Also ships couldn't approach the coral reef without risking getting stuck, and at the same time it was too far from the shore for the average swimmer, isolating it from human contact.
So if boobfishes of uncommon size could be discovered somewhere this would be the place.
The day was perfect: a spotless sky, the bright summer sun, an emerald sea. In the distance Tom could distinguish the shape of the coral reef through the crystal clear water, which was about 3 miles away. He could have borrowed a small raft to cover the distance, but his daily boobfish hunting trip had made him an excellent swimmer.
One last time, Tom checked the heel straps of his swim fins, placed the breathleaf under his tongue, and set off.
It took him a little more than an hour to reach the reef, by then his muscles were starting to ache. So he let himself float face down in the water, arms spread wide, enjoying a view that was impressive both in size and colors.
He got lucky a few minutes later as a school of boobfish passed below him. It was the first time he saw that many together, there must have been at least three dozens of the creatures. He launched after them in a swift motion, catching up effortlessly.
