"I am making you better, making you even more perfect than you are now, from now on as you feel and give into pleasure, you will transform, if you orgasm you are lost forever." I said to her.
Mom sputtered and tried to push away but stopped with a moan when I increased my hold with the ring. I lifted her and pinned her to the wall.
"You can't resist it, I will conquer you, and make you my mermaid" I whispered in her ear. She shudders away with a small no. I caressed her breasts and sucked on her neck.
"Don't you love this mom, don't you want to give in. Just say it, it will be so good, call me master!"
Her hair was all blond now, and tears fell as she nodded.
"Make me a mermaid master, fuck me until I have a tail, please make me yours" she cried.
