You are finally home. You look up at Katie before she knows what is going on. You pull her straight into the water and kiss her that while you are kissing her some of your energy transfers into her which means she will be like you soon.
"Why did you pull me in and kiss me. Not like it I didn't like it? " Katie said.
"You will find out. "You say.
You see her face going from happy to worried and about to try and get away.
You grab hold of her tightly and keep her where she is.
"What are you doing? Let me go!"Katie shouts at you.
"No. I did say you would be rewarded for returning me. This is your reward from the human world they are destroying." You say like the real you has finally been released.
You can see the terror on her face as she keeps trying to get away. Then she stop looking down at her legs to see them merging together and shaping into a golden tail. She notices that she is now naked. You continue to look at her and she starts looking at you. Then you kiss her again. But this time she didn't resist you. Instead of trying to push away. She kissed you back . You feel more energy transfers from you to her and you watch as her breasts turn bigger to your size and the same scale Bra like yours appears on her.
Her transformation has been completed. She looks at herself and turning towards you and say.
" I'm a mermaid. "
"Yes you are a mermaid forever. " You say
"Why? "She asked
"Because I wanted you as my mate and together we can change this world and make it ours. Mer kind rising again.
You are now one of us now. You belong here with us forever and free from the human race. " You say.
She looks at you for another second before you reliase her mermaid passion released from captivity. She then kisses you making her wanting you to take her as your mate.
Without knowing it you both was having mermaid sex and you both climax. You both know that you are carrying babies you will protect each other together.
She then loves her new body she doesn't even remember her human life or care for it. She is wanting the same as any mermaid does. The whole world changed to mermaids forever.
