Try to clear her thoughts (and fail).

Despite how risky the situation was, Anna still couldn't trick herself into doing anything about how she was bottomless. She could slide her panties back up. She could attempt an improvised repair to her skirt using paperclips and hairpins.

Instead she allowed the lower half of her wardrobe to sit loosely atop her lap. She liked how it was just sitting there, not on her body. It seemed like she was getting away with something truly risky, bold and naughty. It was like she was still covered, but at the same time she wasn't. That clothing was covering her, but it wasn't on, which made a world of difference to Anna.

"..." Anna was red faced and hesitating. She opened up the book in front of her, and glanced around, before grabbing her thin panties and placing them on the pages. She then shut the book, hindering her access from proper cover.

She gulped, trying to keep her breathing steady. If she needed to get redressed, if she got caught, the process of getting decent again just got slightly more complicated. It meant she would spend a longer time exposed, a longer amount of time undressed.

She squeezed her legs against each other tightly. The heat was getting more and more intense. Anna slid a hand under her skirt to inspect herself. Her sensitive skin was feeling slick and a little moist. She was turned on for sure.

Anna took a look to her left. Students were either sleeping or watching the movie. She looked to her right. It was the same situation. Anna's hands shook as she picked up her skirt, and folded it as silently as she could, before placing it underneath her book. It was a small, additional amount of isolation from her clothing. She still had them, but again her redressing time was increased.

What would happen if she were caught like this? How would she explain it? Could she explain it? Her hands slowly traced over her bared thighs. Everything from her hips to her ankles were exposed.

Taking more off was tempting, but also risky. Could she do it? There was still plenty of time to do an improvised repair on her skirt. However, there was also plenty of time to explore the feelings she was experiencing.
