Ginny looked to Pansy out of the corner of her eyes. she squirmed self consciously as Pansy looked disinterested or even bored. "Is this...what you wanted?" Ginny asked, her voice soft and weak and a little shaky. As weird as this was, and the hint of shame she felt, Ginny was remarkably aroused. She blushed as wetness clung to her fingers and was easily visible as she touched herself.
Slowly, Ginny nodded. She took a deep breath and closed her eyes. Pressing her fingertips to the swollen button atop her folds, she began to stroke in slow, firm circles. It was hard to pretend she wasn't being watched.
It took a few minutes but soon her breathing was quick and ragged. She dared to open one eye to make sure Pansy was doing what she said she was going to do. Meeting her gaze, Ginny pulled her fingers away so Pansy could see how wet and swollen she was.
