Hypnotic Submission Dust and Mermaids

The Siren: Before being mind controlled, she is sleepy but cocky, she loves her beauty sleep and if she is needed for anything that interrupts that, she is not exactly cooperative. Whilst under mind control, she is way more cooperative and obedient as her brown eyes glow purple. With her seeing the POV character as her master and would to all she can to fulfil his desires. And once she gets her own slave, she becomes more lustful, confident, malicious and horny when talking to it and commanding it for mundane or sexual commands.

Mermaids: Before being hypnotised by the siren. Personalities may vary from mermaid to mermaid, but they share traits like being kind, relaxed and not all too bright. As they are being hypnotised, their eyes sink, their jaws slacken before reforming into a stiff, wide, closed grin across her face. Their movements slow as they stop what they were doing and swim towards the entrancing sound, stopping just underneath the water when they are close enough to the siren before simply sinking like stones to the sea bed, limp and near lifeless as they slowly submit to the powerful song. Finally, once they have fully submited to the son, their eyes widen as their grins remain as they are, creating a goofy, mindless image on their faces. One touch on the forehead by the siren and their bodies return to motion floating in place under the water unless to told to move. Their eyes remain wide and mindless with the occasional chance of their eyes being slightly lower if the mermaid was already tired before they heard the siren. Their responses are short and blank, with no real sense of a personality. Their brains have now been reprogrammed into serving their masters without any sign of any possible return from the spell. They are now mindless, empty vessels acting as slaves.
