You are a scientist researching Sirens. There are a few caught, four of them, Aerywn, Reed, Lyre, and Dorian. They are all four male, pure sirens.

Aerywn has a red tail, red sharp eyes, and long black hair. He acts like he is royalty, and is super cocky and confident, always expecting to be pampered and craving attention.

Reed has a green tail, green soft doe eyes, and long brown hair. He is super sweet and kind, loves to play and joke around, and is a sucker for compliments and soft touches.

Lyre has a blue tail, blue sleepy eyes, and long blonde hair. He is always tired, either sleeping or resting. He is dim and for the most part, boring.

Dorian has a purple tail, purple cold and dark eyes, and long black hair with dark brown highlights. He doesn’t talk much unless he has to when it comes to humans, not very trusting of them, though he has gained a special trust for you specifically. He is a cold male, very blunt and not the most caring or kind.

You slept at the lab, as this was a special 24/7 scientist job. You had your whole own bedroom in a separate room, which any of the four sirens could swim to at any time since the big aquarium made up the walls and was all connected. You had your decorations, a nice big bed, clothes, etc. There was even a small pool so the sirens could exit the aquarium and get in the room with you to sleep in your bed, or use the bathroom, or anything. There was even a separate dresser specifically for the sirens, that held boxers for them, and pajamas as well as just casual comfortable clothing, and socks. On top of the dresser was a variety of hairbrushes, combs, hair ties, scrunchies, and a hair dryer, all for the sirens.

It was currently late at night, around 11pm, and you were lying in bed in your pajamas, when you heard a small splash. You sat up quietly to look at the small pool to see who entered of the four sirens.

Lyre quietly had came in, exited the aquarium, and was now lying on the floor, drying off with a towel so he could transform to his human form.
