It was just another after-school training day for Melissa and her teammates. They always had a free hour after school before their training since the pool was scheduled for another elementary school which pissed her off.
As a girl in junior year in high school, just like her teammates Melissa was a hot one. Standing 5'8, she had nice B-cups, long and curvy swimmer legs, wavy black hair cascading down her well toned body and a cute half-asian face, she was a babe dressed in her school uniform.
Waiting for her annoying training in the cafeteria was another torture for her. She really liked horsing around in the campus with her 'bff' Andrea when it was warmer outside but she was stuck here for the moment due to the harsh winter. Good thing Andrea was also in the swim team so Melissa had a companion to suffer this boredom. Most of her teammates usually studied in the library during this time but it was not her preference at all. Just like Melissa, Andrea could easily pass as a model if it was not for her height. She was a very petite one, standing 5'3 she was very jelous of her teammates. Blond hair, sky blue eyes she was a miniature german girl.
When it was finally time to go to the lockers to change Melissa continued her daily routine and made her way.
Locker room was a chaos as always. 12 years old girls everywhere dressing up after their practice. The school indeed had a small locker rooms that couldn't even support two teams at once.
There was one blond girl that caught Melissa's attention. She was still dressed in her swimsuit, sitting on the bench holding her stomach, bending over and breathing heavily. Getting both disgusted and annoyed Melissa pushed her away from the bench.
'Move it dumbass! Hurry up and leave!'
Falling on to the ground from the bench to her knees she still didn't move at all.
'Didn't you f*cking hear me? COME ON!'
Just then Melissa Realized thick black hair growing out from the girls shoulders. A high pitch scream followed as the little girl completely fell on her back and holding her privates. The entire locker room became quiet and watched the little girl transform.
Breathing heavily, the girl was rubbing her privates. An unmistaken buldge started poking out of her swimsuit and kept growing and growing until it was a 9 inch beast ripping out of her swimsuit. The girl was crying and moaning at the same time as she didn't know what to do with the large hairy penis sticking out of her groin.
She grabbed her new penis with both of her hands and started pumping. Huge amount of cum sprayed out everywhere just when her balls dropped and arms gained weight and muscle. Her torso finished growing, completely destroying her swimsuit. Well defined abs formed as her feet and legs gained muscle and hair to support her new upper body. Lastly her hair retreared back to a buzzcut as her facial features transformed to a 18 years old male.
Cleaning the jizz on her face, Melissa was more than shocked to see what just happened. There lay a 6'2 guy on the ground with a penis on his hand where a 12 year old girl had been.
Everyone screamed and ran away from the lockers as Melissa started feeling dizy...
