Kelly pantsed Isabel of her panties

(chapter originally by hanskumoekk at writing.com)

*GASP*

Isabel's body jumped and she gasped when she felt two hands grab her panties from behind out of nowhere. It took her too long to react before the next move happened. Isabel squealed. Kelly, Stephanie and Heather laughed.

"Wooooo!" Heather shouted out mid-laugh.

"Surprise attack! There's something you lack, 'cause we can totally see your buttcrack!" Stephanie taunted with a fitting rhyme, and she was absolutely right. Isabel realized that she was in fact standing with her panties pulled down to her knees, bottomless with her now completely bare butt exposed to three girls she just couldn't stand. At all.

As an instinctive reaction, Isabel threw both of her arms to cover what had to be covered, one hand shot to cup her crotch, while the other arm was placed along the buttcrack, attempting to shield what she could of her bare derriere from her three tormentors. The feeling of shame and embarrassment came rushing down over her. As a very modest girl, no one had ever gotten a glimpse of her bare butt before, let alone any naked part of her. Until this very moment.

"Nuh-uh! You're not hiding yourself this time!" Kelly said as both Stephanie and Heather began to pull at her arms, trying to **** her arms away from her naked butt and her crotch. Isabel fought back valiantly, but this was only a ploy to extend her humiliation: As Stephanie and Heather pulled at her arms, Isabel began to move her feet. Kelly proceeded to pull the panties further down Isabel's legs and made Isabel step out of them in her struggle to keep her arms covering her modesty. When they released her arms, she realized that she had moved several feet from her earlier spot.

She turned around in quick fashion, both her hands shifting to her bare crotch as she looked at Kelly, Stephanie and Heather in utter shock. The first sight that met her was Kelly waving her panties in the air right in front of her.

"You're bottomless and I've got your panties!!" Kelly teased, making Isabel almost shiver of embarrassment.

"GIVE THEM BACK!" Isabel yelled.

"Oh you'll have your chance to get them back, but you'll have to work for them!"

What are Kelly's options for Isabel?
