In the ancient times, when Greek was at it's finest, legends and stories were told about the Strait of Messina, where two sea monsters would guard that passage between Sicily and Calabria. Well you were on a boat of merchants that without any choices it had to go through that dangerous path, You were chosen as one of the six human sacrifices for Scylla, the six headed sea monster.
When you got inside the dark and humid lair, many Wrecks of other boats were scattered around in the waters, that sight alone made some crew members doubt that the six sacrifices wouldn't satisfy the monster now swimming under your own boat. Suddenly something bumped under the ship making you fall into the dark waters, the other proceeded without looking back, but soon they would be repaid for their infamy.
You started sinking down as the shock of the moment made you stood completely still to try and avoid getting spotted by Her. However two pale eyes looked at you through the darkness of the abyss as they got closer; from above some light came as the ship light on Five torches, slightly illuminating the sea monster that was close to you: the Bust of a woman, from the waist up, with palmed hands, siren like ears, sharp teeth typical of abyssal fishes and long dark hair, was all attached to a gaping like mouth with several petals like appendages full of razor sharp fangs; that part was connected with six other giant Moray Eel heads (big enough to eat a man whole) which had four eyes each; you couldn't see lower than that but you presumed that the rest of the would would resemble a sort of amphibian creature with claws and a long tail.
Anyway... Scylla was right before you, having a wide creepy smile that made you tremble more, if that was remotely possible, and closing up to you in the water, however she was quite slow as she seemed more interested in you than seeing you just like another prey. She got closer enough that the bust of the woman was almost embracing you, the thought of lashing out to her crossed your mind, however the gaping mouth beneath the bust wasn't going to allow you any way out.
The monster kept staring you for some other moments before embracing your body with her arms and gently closing the fleshy petals around you and the bust of the woman, trying not to crush you in a blood puddle. Then you felt everything moving as she swam somewhere else; you started losing oxygen, however she finally opened the petals letting you out onto the rocky shore of another part of the cave.
"Stay here, little fish~"
She said with a strangely seductively before disappearing back beneath the dark veil of the waters. As she was gone you started looking around for a way out of the cave, however, apart from some cracks in the ceiling that let some light breach in this secluded zone of the lair, there was nothing else, probably the entrance of this zone is underwater, from where you were brought by Her. In the meantime you started hearing screaming and crying from the crew of the boat that let you die in the lair, it seems that Scylla is devouring everyone on board, but you could only hear their screams.
15 minutes passed and the scream suddenly ended, then the bust of the monstrous woman appeared from the pool that connected this side of the cave to the rest (The bust of the woman is of a normal size, while the rest of the body is enormous underwater). She looked at you with the same smile of before and those pale eyes, two of her Moray Eel slowly came out of the water looking at you.
"Your companions were quite the appetizer, little fish~"
She said sadistically before laughing amused by your terror.
"But you don't have to worry though, the goddess Aphrodite has blessed you with a beauty that is quite appealing to me~"
Her tone become more sultry as she licked her lips with her long tongue.
"I'll keep you alive as my final dessert."
The giggle that came from her made your blood freeze in your veins for the fear of what it has to come.
