The mermaid's words do not even faze you. You sucked in classes of literature but you know what to answer, assuming the mermaid is even telling the truth.
"Ha!" you scoff. "Poseidon's a Greek god so he must have so many kids he won't even notice you're gone. If he even knows you exist. I've seen all of your sisters too, and I am sure they're in the same case. He won't care or know."
"You cad!" yells the mermaid in utter outrage, which only makes you laugh more.
The mermaid screeches and yells but you try to ignore her. After all, you have a long way to go and you're not even out of the beach yet. The mermaid's screams are annoying and the wails and snivelling of her friends and sisters are not at all pleasant. She's getting heavy on your shoulders but you don't care. The idea of fucking her, selling her or exhibiting her - or several at once - is enough to make you put one foot forward after the other. However, you don't even leave the beach.
Because a sudden booming sound erupts and when you turn around, you drop the mermaid to the ground. In the distance, lightning erupts from very black clouds and thunder booms menacingly. And from the sea a huge figure rises, its beard like seaweed and its trident very much in evidence.
"Father!" gasps the mermaid in utter relief.
Uh-oh... That cannot be good... The figure flashes an angry stare towards you and booms in a deep voice, an impressive voice:
"You dare abduct my daughter, foolish mortal?"
"I thought... I thought..." you stammer. "I thought you would not care. Not notice... Because... Because usually... you don't..."
"Well, sometimes I do, and this is one of these times!" the voice thunders.
"I am sorry..." you plead.
"Oh, now you are sorry," growls the god. "But did you even imagine what you wanted to inflict upon my daughter?"
"I..." you start. "Yes! I am sorry!"
"Liar," argues the god. "You had no kindness until I made my appearance! To punish you, you will now how it feels to be a mermaid, and suffer what YOU wanted to allow for my child!"
Poseidon points his trident in your direction and after seeing flashes coming out of it, you black out as the magic hits you.
When you wake up, the sun is shining and the sky is blue. The sea is completely calm and no mermaids are around. For a split second, you think you've dreamed it all. But then you see your blue and green fish tail. Your dainty webbed hands. Hair that is bright red and falls in luscious locks. Your legs that are gone. Your enormous boobs. Your nakedness. You touch your face and feel delicate facial features like big round eyes and full lips that seem completely kissable. You shout in horror. You're a girl! A girl! And a mermaid! You can't be a hot girl! With boobs! You're a guy! This was not a dream and you're in a nightmare still! This is a nightmare! A pure horror!
Then you hear a sound behind you and realize things are about to get worse. Because behind you is a threat. A threat that is male. And that has clearly a massive erection.
