Summary
Any work at sea was dangerous because of the merfolk and you had learned early to be wary, to watch the water and the fish and to react fast the second something felt even a smidgeon off to you. You had no desire to get attacked again, to add to the scars you already carried on your body.
Mers were monsters in your opinion and the less you had to do with them the better - right up until the day you met one of the most dangerous mers of your life. A siren with eyes bluer than the sky and sea combined and hair the color of shimmering frost. Where others saw a divinely beautiful creature all you saw was death smiling back at you.

Summary
“Taehyun, you don’t even know what my theory is yet.”
“Then what is it?” Taehyun pressed. His brain was already hurrying to put the pieces together, speeding through different theories on how Soobin could possibly know who was involved with the murders. Did he overhear something? Was he close with one of the victims? Did someone confess to him?
“I just need you to make me a promise first,” Soobin said. He reached for one of Taehyun’s hands, squeezing it tight. “Promise that you’ll hear me out. If you don’t want to believe me, just forget I said anything.”
After a chance encounter on the beach, Taehyun begins to fall for Soobin, a siren who is connected to a mysterious string of murders in their small town.

Summary
In their Alternate Universe of It's a Terrible Life (Season 4, Episode 17), Dean Smith (Dean Winchester) and Sam Wesson (Sam Winchester) left their nine-to-five lives behind, and here they were in Massachusetts, by the ocean. They routinely traveled, saved lives, hunted monsters, and undertook various odd jobs for money. They were still figuring out how to live and have an income while saving people. They'd managed by selling off their belongings, giving them a small financial cushion until they could find more stable means, but they were now close to running out.
An opportunity arises to hunt a siren, and Dean jumps at it. Sam wanted to hunt something other than ghosts, and the small town is paying for their entire stay, so it's a win-win...Right?

Summary
Water. Cold, heavy, dark. A burning, in his throat and lungs. A song echoes below Kaveh, akin to the mournful call of a whale. The singer's voice is eerily familiar. Scales brush against his skin, the song pausing long enough for a single phrase, whispered in Sumerian:
"How has realizing your ideals gone for you?"
<><><>
Kaveh's unlikely friendship (and subsequent fight) with Alhaitham, a mer from the deep sea, leads to what might be the ocean's worst roommate situation after Alhaitham saves the architect from drowning

Summary
I told you I like these fish too much...
This is a smut collection of stories pertaining to my mer au fic, Over The Deep End. None of these are canon, but if you want them to be, then indulge!~
Some of these stories might take place during the main story or after the events of the story. I'll be sure to say so in the Summary and list any spoiler warnings and/or what chapters things take place during.
I won't be updating this regularly, as these are all pure indulgence, but I have a good handful of smut ideas I'd like to write for these goobers. So we all may feast on occasion hehe!
That being said, enjoy! Minors DNI!!!
