A simple trade

Feeling a pit of dread beginning to well up in her stomach, Anna begins to text back.

"What do you want?" She typed in, sending it over. Almost instantly, the phone vibrated back with an answer.

"A simple trade; your panties, for the underwear of Emily Anderson, one of the school cheerleaders. I will guide you to your goal, all you have to do is follow my orders. Listen, and you will have these back in no time. Disobey..."

Another message appeared, this time only reading; "...and I'll take another item from you as punishment. And don't even think of telling anyone about this, or I will have to punish you for that as well. So? Do we have a deal?"

Anna stared at her phone, the cool air from the hallway making the bottom of her skirt sway slightly, reminding her of just how naked she was right now. So if she wanted to get those back, she'd need to steal the bra and panties of a cheerleader?! If this person could see where she was right now...they were either close, or had access to the school's cameras. Should she agree to the mysterious person's demands, or refuse and try to find where they are herself?
