High school seniors: First day of the curse.

The curse began exactly one week after Jill and Tracey's 18th birthday. In the middle of a school day. Jill and Tracey were two of the most popular girls in school, and much of the time, they wouldn't give their "lesser" classmates the time of day.

This made one classmate quite resentful. Amanda had been a friend of the twins in their youth, but was now a social outcast, considered by Jill and Tracey to be beneath their notice. Said resentment had been boiling up inside of Amanda for years, and had recently led her to witchcraft.

When Jill and Tracey were changing into her gym clothes, Amanda saw her chance.

As Jill put on her gym shirt, both Tracey's gym shirt and bra vanished, leaving her topless. However, she didn't immediately notice, instead focusing on putting on her gym shorts. Which made Jill's shorts and panties disappear, leaving her bottomless.

Soon after, the twins turned to look at each other. And started snickering.

"Surely you aren't planning on going out like that?" The twins said to each other, almost in unison. "What do you mean?"

Then Jill and Tracey finally looked down at themselves. And screamed, Jill moving her hand to cover her womanhood, while Tracey covered her nipples with her arm. Jill was the first to speak up.

"Umm.. have you seen my pants?"

The clothing that had vanished off their bodies was nowhere to be found, and gym class started in less than five minutes. The way the twins saw it, there were two possible courses of action. They could either attempt gym in their normal school uniforms. Without their underwear. Or they could try and break into one of the other lockers and steal someone else's gym uniform.
