Once the bus arrived, Jenny got off and started heading to the girls' locker room for her first class of the day, gym. Everything was as usual when she came in, with everyone changing and talking. As Jenny started changing, she noticed one of her friends, Amanda, arrive. Jenny, being bisexual, had always thought Amanda was hot, but had never brought it up to anyone. Now was her chance to really enjoy things.
Under her breath, Jenny muttered, "I wish Amanda's gym outfit was a bit smaller."
As Amanda started getting on her gym uniform, the changes were noticeable. Her shorts hugged her ass and gave her a bit of cameltoe, while her shirt framed her breasts well.
"...Huh?" said Amanda, noticing something odd. "Did this thing shrink?"
"...Maybe it shrunk in the wash?" proposed Jenny. "It's happened to me before."
"...I guess you're right," admitted Amanda, going out into the gym.
Jenny did her best to keep her glee secret, knowing that things could only get hotter from here.
