Summary
Michael Afton was only five years old when his world changed forever. Born from the love between William Afton and Roselle, an enigmatic woman with ocean blood, Michael inherited a secret: he is a merman. His mother taught him to love the water, to respect its power... but also warned him of the danger of revealing it.
Everything falls apart when William returns from one of his extended business trips with heartbreaking news: he has a mistress, is pregnant, and wants a divorce. Roselle, devastated, commits suicide. Michael is torn from his home and taken to another country, to a new life with his cold stepmother, two curious stepbrothers, and an emotionally absent father.
At just five years old, Michael is forced to hide his true nature. A simple drop of water can trigger his transformation in just ten seconds. His gills, his sea-like tail, his connection to the ocean... everything must be kept secret.
But the power of the sea is not so easily contained. Michael's emotions—anger, sadness, fear—threaten to overwhelm his abilities, and he's already lost control more times than he cares to count.

Summary
“Look. We keep doing this. You say it won’t happen again. I say it’s already happening. So here’s an idea...”
“No.”
“You haven’t even heard it yet.”
“I already know it’s going to be dumb.”
“Let’s make a deal.”
She stared at him. “A deal?”
“Yeah.” He stretched, completely unbothered. “Just sex. No strings. No feelings. No dating. We do what we’ve clearly got zero self-control about anyway, but without the guilt trip after.”
“You’re out of your mind.” -

Summary
I have several mermaid OCs swimming around in my brain, so I figured it would be a good idea to solidify their identities like this. These are some brief character bios for my six "bonded" mermaid OCs, as in all six of these characters are packaged together in my mind. They all grew up together as fairly close friends in a small but progressive beach town in the southeastern United States. One day, during the summer after their junior year of college, they were cursed (or blessed) to transform into mermaids when they touch water, or when they orgasm. A very H2O: Just Add Water-like situation. They each have adapted to this drastic change in their own ways and have relied heavily on their close friendships with each other to survive and maintain some sense of normalcy where possible.

Summary
Tommy has feared mers all his life - elusive creatures of the ocean, the only remaining form of magic in the world, only surviving because they were so far from the touch of man. But they were more than elusive - they were evil, merciless, human-killing machines that killed his mother and his brother when he was six.
At least, that's what he thought. Until he comes face-to-face with magic and, for the first time in his life, begins to question the world his father has built for him.
