Leaving it open, she lied in wait, head barely above the water. She watched as Jennifer opened the door, a pondering look on the other girl's face as it was shut and locked. Then, instead of using the toilet, she watched as Jennifer leaned against the door, grasping her skirt and pulling it up.
Felicity didn't know what was going through Jennifer's head, having barely enough visibility to watch as the girl stared at her shorts for a moment, gaze drifting to her chest before moving back under her skirt. Then, nervousness and uncertainty on her face, Felicity watched as Jennifer ran a hand across her covered crotch, hand between her legs. "What's she doing?" Felicity thought to herself, making sure she didn't say that out loud.
Curious what her friend was doing, Felicity stayed quiet, and simply watched. Jennifer pressed the palm of her hand against the cotton covering her crotch. A grimace, more disapproving, crossed Jennifer's face as she adjusted her hand, sticking two fingers deeper, the fabric penetrating her privates momentarily. The peeping tomboy couldn't help but wish Jennifer was mumbling to herself, so she at least had some idea of what was going on.
Felicity saw an unsatisfied look cross her friend's face, before the girl removed her hand and dropped her skirt with a huff. "Dammit," Felicity heard her whisper, before Jennifer grasped the hemline of her skirt, peering at her crotch. The unsatisfied look was replaced with relief, before a blush joined it, as if she was thinking of something inappropriate.
Jennifer tugged her shorts down further, a bit more of her crotch revealed, before the girl walked over to the toilet. Felicity held her breath, hoping she wouldn't be spotted.
