In cuve [Siren Fetish Perspective]

Waking up Katie was totally afraid. She had a long pipe system going down her throat. Fear of suffocation! But she had no trouble breathing. She was in a tiny vertical tank. Just the place to float. She wore a complex and complete set of siren in neo-latex. Her legs were joined together to form a tail and fins completed his armband. Her breasts and her crotch remained uncovered.

Quickly the water from the tank was sucked, leaving Katie in suspension, just held by the pipe in his mouth and headgag. The glass of the tank went down, revealing to him a room similar to a pumping room. A technician was standing in front of a console. He approached her to explain the situation.

"This is the beginning of your new life. You were commanded by a wealthy senator. He wants a mermaid to decorate his aquarium. He did not want a heavy siren type change. He wants you to keep a relatively human appearance. Your skin has been treated to bear long exposure to water as well as the constant wearing of your suit. Your stomach has also been reduced in favor of your lung capacity. You can hold it longer under water. Approximatly one hour. We have modified your vocal cords so that we can emit a marine melody, more in the theme. Nothing very bad. Look at that !"

He shows her a basin in which women evolve into true siren.

"But if the changes were mild, you will have to work hard to satisfy your new owner. We will train you physically to meet your expectations."
