She begins to blush
"You sure? Theres no going back. You won't be able to walk amd you will no longer be a male either."
You tell her you are certain.
Before you can even finish she kisses you and you feel you body begin to change.
Your hair grows long and becomes light blue.
You shirt morphs into a seashell bra and you feel you chest swell until it feels just right up against you skin.
You feet fuse into a tail with blue scales.
She giggles "You look amazing!!"
She then grabs you hand.
"Cmon lets swim together Aqua!!, is it okay if I call you that?"
You smile as you enter the water
"Thats a perfect name for a mermaid".
You swim with pure bliss knowing the two of you will be together as mermaids.
