Sally sighed to herself as she sat underneath her umbrella. She was at the beach, and appeared to be the only one there. She had gone there in the hopes of spending some time with her friends. It was summer vacation and she wanted a beach day, so she called up her friends and told them to meet her at the beach. Alas, here she was. All by herself.

She was in her bikini and everything. She even brought her purse with her so they could grab something to eat. Instead, here she was, sitting underneath a beach umbrella all by herself.

Not wanting the day to be wasted, Sally decided to just go swimming anyways instead of mope around until it got dark. She stood up and walked over to the ocean with the intent of having fun. As she walked she had noticed something shiny in the sand.

She crouched down and dug the shiny object out of the sand. In her hands was a shiny blue stone resembling that of the water she was going to swim in. She walked back to her umbrella and placed the stone in her bag. Perhaps she could use it in the future.

She walked back over to the water, not noticing the stone had now lost its shine. As Sally walked to the water, she began to change. Her skin began to change color, becoming this light blue tint. Sally noticed this and gasped at her new skin tone. She also noticed her skin had became very smooth and shiny.

She then began to feel an odd tingly feeling from the waist down. Sally's but then began to grow, making the poor girl gasp and panic. He thighs also began to grow, becoming thick and plump. Her ass also very big and bubbly, desirable amongst most women.

She then felt her tailbone beginning to extend as a large tail protruded from her behind, with frills to make it look more aquatic-esq.

She then began to feel the tingling affect her from the waist up. She moaned as she felt her breasts beginning to grow from C-Cups to DD-Cups, with her nipples turning a dark blue.

Sally's hair then fell out, with yellow frills taking its place. Her head then stretched to a semi-canine shape. Her fingernails and tone nails began to fuse with her toes and fingers respectively, turning the same light blue color her skin was. Dark blue pads also formed underneath her feet, similarly to those of a canines.

The final change was a big frill that surrounded her entire neck.

Sally stood up and looked at herself. She had transformed into a Vaporeon Pokémorph.

Sally looked at her new body and felt her "enlarged" features. Despite what had just happened, she couldn't help but feel slightly aroused by this. Something she rather liked. She looked at the ocean water she just remembered, and thought that since she was a Vaporeon now (an anthropomorphic Vaporeon, but a Vaporeon none the less), she was probably better at swimming.

...

A couple hours later, Sally's friends finally arrived to the beach. One of them bought lunch, even making sure to get Sally's favorite since she was probably pissed that they didn't arrive earlier.

They found her things underneath a beach umbrella, but Sally wasn't anywhere to be seen. They then looked to the ocean to see a Vaporeon Pokémorph exit out of the ocean; completely nude. "Hey girls!" Sally greeted.
