Samantha swam up to Joey when he was on the side of the pool and asked him
"Hey Joey can you change us into the forms that we love most please?"
"OK Samantha. I wish that Anmanda and Samantha would have the bodies that they love the most."
With that Samantha went into the middle of the pool and went swimming then all of a sudden they both disappeared from view for a minute, Joey was worried that they both have died.
Suddenly there was a lot of thrashing around in the lake as Joey saw a form that was changing and growing bigger. Soon later he watched in awe as they both walked seductively out of the water and towards him. He saw that Samantha was covered in fine black scales. And had grown to a height of 15'8" with close to 1000 pounds of pure muscles and a impressive rack of FF breasts with a tail close to 9' long with long tentacles for hair and sharp jaggered talons on her elbows and for fingernails.
Joey then looked over to Amanda which was standing there at a height of 16'5" and muscled out to the max for the body thet she has Joey looked at her long reptilian tail. Joey looked at her skin to see it being scaled like a snake and saw her GG breasts. Joey looked at a glint that was on the fingers of both of them to see two rings identical to his he only realised too late that Samantha tricked him to make them the ultimate goddesses with power of all of matter.
Then he feels a tingley sensation in his body as the changes started
