Evolving as a Human-Pokemon

Sunset found herself being called out of her ball. A sensation she had gotten used. It was like going to sleep and waking up refreshed once you were used to it. All of her injuries were healed after a good rest. In this case she found herself in the middle of a battle. She was only mildly annoyed that Mass didn't give her swimsuit back after last night.

"Sunset use Mega Punch and finish off that Pikachu" Mass ordered.

She punched the Pikachu and knocked it out. A cold hard blow. The pokémon was knocked out and recalled by the purple haired lady who commanded the pokémon.

"Well it seems I have lost" said the lady.

"You know what that means" Mass said, taking out a pokeball.

"I do. Is there anyway I could talk you out of it?" ask the woman.

"Nope" Mass said, tossing the pokeball at the woman.

She was sucked inside the red and white ball. Sunset watched in excitement as she helped capture someone else. The sense of horror she once felt was long gone. This was the exciting reality of being a pokémon now. After a moment of shaking the ball clicked shut and disappeared. It was sent off to the storage system.

"Good job Sunset. You did great work" Mass said, his words filling her with praise.

These words triggered something in her. A change of some kind. She felt herself erupting with some kind of energy. Her vision was enveloped in some kind of light. Her body was changing. Her chest grew larger. Her hips grew wider. Her legs became longer and her thighs became thicker. Her rear developed a nice bounce. Her waist became slimmer and more toned. Her blond hair grew longer.

"Oh my Arceus! Sunset! You evolved into an even stronger human. This is amazing" Mass said, in excitement

"Okay... This was completely unexpected" Sunset thought, as she took in her... evolved body.

All she knew at this point was that she was sexier and that she needed a new swimsuit.
